[0003] The existing film laminating machine has disadvantages such as complex operation, high preparation and operation costs, and its structure and
layout need to be further optimized, which is specifically reflected in the following aspects
[0004] 1. The structure of the extruding device in the existing film laminating machine is complex and the production cost is high: first, the glue outlet of the extruding device (screw extruder) is connected to the extruding device through a
thermal insulation hose. The length is about 1200mm, and it has special production requirements, and the production cost is relatively high; while the glue dispensing device is fixed on an up and down movement mechanism. It is convenient for the
extrusion nozzle of the glue
discharge device to be inserted into the film for glue application, and a set of film
hooking mechanism is also set to hook the film rolled on the material
guide tube; when not applying glue, the up and down movement mechanism moves upward to squeeze the glue The
nozzle is far away from the material guide
pipe. Since the
extrusion action cannot be stopped when the glue is applied or not applied, the speed can only be slowed down, otherwise the
extrusion nozzle will be blocked, which requires a glue connection mechanism. The existing The glue splicing mechanism is driven by a set of rotating mechanism to turn over for glue splicing. Its structure is relatively complicated, which increases the production cost and the difficulty of debugging.
[0005] 2. The material in the existing mold clamping machine is driven by two synchronous
belt drive mechanisms, and the two synchronous
belt drive mechanisms are only driven by one motor. Tooth skipping, poor equipment stability
[0006] 3. The working efficiency of the gluing device in the existing film laminator is low: the gluing wheel used for gluing in the existing laminator is cylindrical, and the upper part of the
guide tube that fits the gluing wheel is flattened to make it It has a small surface, and then presses the glue through the flat contact pressing wheel. However, there has always been a big problem for small-
diameter charge machines, that is, how to increase production capacity, and the
bottleneck of increasing production capacity is the inner
diameter of the material
guide tube. Size and length, because the outer
diameter of the guide tube and the collar shaper are limited by the size of the
drug roll itself, if the outer diameter cannot be increased, it is possible to increase the production capacity only by increasing the inner diameter, but as mentioned above, the upper part of the guide tube should be flattened The glue pressing method makes the tube wall of the guide tube must be made thick, so that the upper part of the guide tube will not be
cut through when the upper part of the guide tube is
cut, and the result of thickening the tube wall under the premise of the same outer diameter is to make the The inner diameter of the guide tube is smaller, which greatly affects the passing capacity of the filling material, and also greatly reduces the production capacity and production efficiency of the laminating machine.
[0007] 4. The forming device of the existing film laminating machine includes a collar former and a material guide tube, but the collar former and the material guide tube are respectively fixed on the vertical plate, and installation and replacement need to be performed one by one, which is inconvenient to install and replace ,low efficiency
[0008] 5. The speed synchronization device between the film conveying device and the rotary
punching and
cutting device of the existing film laminating machine drives the eccentric wheel fixed on the rotating shaft to rotate through the swing arm rotating mechanism, and then senses the distance between the eccentric wheel and the eccentric wheel through the sensor Change to feedback speed, every time the swing arm rotation mechanism rotates a certain angle, the distance between the eccentric wheel and the sensor will change to a certain extent, the conversion device of this kind of eccentric wheel has the
disadvantage of
slow response speed, and its synchronization effect will not good
[0009] 6. In addition, in the existing
production line for film laminating and filling, the film splicing machine, automatic deviation correction device, and laminating machine are basically arranged along a straight line. The equipment space takes up a lot, and the distance between the laminating machine and the laminating machine is large It is inconvenient for operators to control and operate two devices at the same time
