How To Choose The Right Dispenser.

Dispensers are used more and more on production lines, so how much do you know about dispensers? Xiaomai will introduce to you the working principle of the glue dispenser and how to choose a glue dispenser. Xiaomai hopes that everyone can better understand the dispenser when using it.

Glue: Ordinary glue one-component dispenser, AB glue two-liquid dispenser, PU glue special dispenser, UV glue special needle dispenser.

Our products also include Glue Dispensing Machine, programming, saving time, effort and labor; PVC Dispensing Machine, which are professional machines to do professional things; and Silicone Dispensing Machine, which are specially designed for products that deal with silicone. machine; there is also an ab Glue Dispensing Machine, which is a double-liquid dispenser. Named because of the nature of glue, it can adapt to two-component glue mixing and dispensing; there is also an 8 Colors Dispensing Machine, a fully Automatic Dispensing Machine, which saves time and labor. If you want to know more, welcome to consult us, we have a large stock in stock and will serve you wholeheartedly!

Dispensing technology: ordinary Dispensing Machine adopts semi-automatic dispensing machine (such as pedal control), accurate positioning and marking select desktop, three-axis, cylindrical and other automatic Dispensing Machines. In fact, the automatic function of the dispenser is an auxiliary function. The glue dispenser plays an increasingly important role in the control of glue, and other functions can be realized by the automatic manipulator.

Work efficiency and environment: few products, low efficiency, manual glue gun is used. Work outdoors, use a glue gun. Accurate control of the race and use of the machine is required. For automatic dispensing, use a machine with automation.

Cost: There are many different dispensing options. Not all dispensing requires a machine, and not all automated dispensing must be attached to a dispenser. In terms of cost, if the glue requires the use of a machine that is too expensive, consider replacing the glue. If the price of a dispenser with automation is prohibitive, consider moving the product instead of the dispensing head.

How the glue dispenser works
How it works: Compressed air is fed into the bottle (syringe), and glue is pressed into the feed tube connected to the piston chamber. When the piston is on the upstroke, the piston chamber is filled with glue, and when the piston pushes the glue drop needle down, the glue is forced out of the needle. The amount of glue drop is determined by the impact distance of the piston, which can be adjusted manually or controlled in the software.
Features: fast speed, low sensitivity to glue viscosity.

Introduction to the working principle of other types of glue dispensers:
1. Dispensing machine - Archimedes dispensing pump:
How it works: The compressed air is fed into the plastic bottle (syringe), the glue is pressed into the feeding tube, and the glue flows through the screw at a fixed time and a specific speed. The rotation of the screw creates a shear force on the glue, so that the glue flows down the thread, and the rotation of the screw continuously pressurizes the glue, making it flow out of the dispensing needle.

Features: Flexibility with no fixed limit on the diameter of the glue point. It can be adjusted by software. However, when a larger point of adhesion is dropped, the screw rotates for a long time, which will reduce the output of the whole machine. In addition, the viscosity and flow characteristics of the adhesive also affect its stability.

2. Dispensing machine - non-contact dispensing pump:
How it works: Compressed air is fed into the bottle (syringe) and glue is pressed into the feed tube connected to the piston chamber, where the temperature is controlled for the best consistent viscosity. With a ball seat construction, the glue fills the void left by the ball retracting from the seat. When the ball returns, the glue flow is interrupted due to the acceleration force, so it is ejected from the glue needle nozzle and drips onto the board to form glue spots.

Features: Eliminates the traditional rubber tip trailing method, the needle drop has no wear, no interference with other parts, no damage to the pin nozzle, no waste caused by the bending of the body, and no damage to the pin nozzle.
