Description

Technical Field

[0001] The utility model belongs to the technical field related to film processing, and particularly relates to glue storage equipment for film glue coating. Background Art

[0002] Film coating is a process for evenly applying adhesive to a film surface. It is widely used in packaging, labeling, medical, electronics, building materials, automotive, and household products. The purpose of coating is to improve the film's adhesion and barrier properties or impart specific functionality. The adhesive selection, coating method, drying and curing conditions, and final application requirements all affect the coating effect. During film coating, the adhesive needs to be stored in a storage barrel. When used, the adhesive is pumped into the film coating equipment using a pumping device. However, in actual use, this method still has the following disadvantages:

[0003] During the storage process of the film coating glue storage equipment, a certain amount of glue is contained in it. However, as it is used, the glue content decreases, so it is necessary to replenish the glue. However, the replenishment of glue can only be done manually, which is cumbersome and inconvenient to use.

[0004] During the working cycle of extracting glue from the glue storage equipment and inputting glue into the glue storage equipment, air in the glue storage barrel will flow in and out of it, causing some of the solvent in it to evaporate and solidify glue to adhere to the inner wall of the glue storage barrel. After the glue solidifies, it affects the composition of the glue in the glue storage barrel. During the transportation process, the solidified glue falls off and causes accumulation in the filtering equipment, causing the efficiency of the filtering equipment to drop rapidly and affecting the smoothness of glue coating. Utility Model Content

[0005] The purpose of the utility model is to provide a glue storage device for film coating. By arranging a platform scale, a glue delivery barrel, a top cover and a glue storage barrel, the utility model solves the problem that the glue storage device for film coating requires cumbersome manual operation to replenish the glue liquid, and the top of the glue storage device is connected to the air, which easily causes the glue liquid solvent to volatilize.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a glue storage device for film coating, comprising a platform scale, a glue delivery barrel, a top cover and a glue storage barrel, a movable sleeve is fixed to the top center of the platform scale, the glue delivery barrel is sleeved in the movable sleeve, the bottom end of the glue delivery barrel is fixed with a compression spring, the bottom end of the compression spring is fixed to the top of the platform scale, a top cover is fixed to the upper portion of the outer peripheral surface of the glue delivery barrel, the top center of the top cover is fixedly connected to a vent pipe, the top end of the vent pipe is fixedly connected to a hollow rubber ball, a glue storage barrel is provided above one side of the glue delivery barrel, when working, the movable sleeve is fixed thereon by the platform scale, the glue delivery barrel is movably connected thereto by the movable sleeve, the top end of the glue delivery barrel is closed by the top cover, and the glue used in the glue delivery barrel is stored by the glue storage barrel.

[0008] Furthermore, a push switch is fixed at the center of the top of the scale in the movable sleeve, and a pressure rod is fixed at the center of the bottom end of the glue delivery barrel. The bottom end of the pressure rod corresponds to the position of the push switch. After the movable sleeve is pressed down by the pressure rod through the push switch, the electric control valve is closed.

[0009] Furthermore, the compression spring is arranged in the movable sleeve, and the compression spring is arranged outside the pressure rod. After the compression spring is fixed on the scale, it assists in supporting the glue delivery barrel.

[0010] Furthermore, a return pipe is fixedly connected to the top of the top cover on one side of the ventilation pipe, and a glue delivery pipe is fixed vertically through the return pipe on the side away from the ventilation pipe. The bottom end of the glue delivery pipe is arranged in the lower part of the glue delivery barrel. The ventilation pipe returns the glue liquid into it through the return pipe, and the glue liquid is transported to the glue pump connected to the film coating equipment through the glue delivery pipe, and then pumped to the film coating equipment through the glue pump.

[0011] Furthermore, a feeding hose is fixedly connected to the lower part of the side of the glue storage barrel, and the end of the feeding hose away from the glue storage barrel is fixed to the top of the top cover. An electric control valve is fixed on the side of the feeding hose, and the glue storage barrel transports the glue therein to the glue delivery barrel through the feeding hose.

[0012] Furthermore, a fixing hole is vertically provided on the top of the top cover of the vent pipe away from the reflux pipe side, and the fixing hole is arranged in the feeding hose, and the vent pipe is connected with the glue storage barrel through the fixing hole.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the glue storage equipment for film coating needs to be manually operated to replenish the glue liquid, by arranging a platform scale, a glue delivery barrel, a top cover and a glue storage barrel. The glue liquid in the glue storage barrel is transported to the glue delivery barrel through the feeding hose on the glue storage barrel, so that the weight of the glue delivery barrel is increased, and the glue delivery barrel presses down the compression spring, so that the pressure rod is pressed onto the push switch on the platform scale, so that the push switch is pressed down, and the electric control valve closes the feeding hose. During operation, when the glue liquid content in the glue delivery barrel decreases, the compression spring is lifted, the pressure rod leaves the push switch, the push switch is released, and the electric control valve is started. At this time, the glue liquid in the glue storage barrel is transported to the glue delivery barrel through the feeding hose, so that the glue delivery barrel is replenished with glue liquid, so that the replenishment of glue liquid does not require manual operation, and the use is more convenient.

[0015] The utility model solves the problem that the top of the glue storage device is connected to the air, which easily causes the volatilization of the glue solvent, by arranging the glue barrel and the top cover. The glue in the glue barrel is pumped into the film coating device through an external glue pumping device. After being used in the film coating device, the glue flows back to the glue barrel through the reflux pipe. When the glue content in the glue barrel changes, the hollow rubber ball is connected to the glue barrel through the vent pipe, so that when the glue content in the glue barrel changes during operation, air will not enter or exit, thereby reducing the solidification of the glue in the glue barrel due to solvent evaporation, and better maintaining the smoothness of glue transportation.

Specific embodiments

[0025] See also Figure 1-5 The utility model is a glue storage device for film coating, comprising a platform scale 1, a glue delivery barrel 2, a top cover 3 and a glue storage barrel 4. A movable sleeve 101 is fixed to the top center of the platform scale 1. The platform scale 1 is used to weigh the weight of the glue in the glue delivery barrel 2. The movable sleeve 101 is used to limit the movement of the glue delivery barrel 2 on it. The movable sleeve 101 is sleeved with the glue delivery barrel 2, and the glue delivery barrel 2 is used to provide temporary storage for the glue. A compression spring 201 is fixed to the bottom end of the glue delivery barrel 2. The bottom end of the compression spring 201 is fixed to the top of the platform scale 1. The compression spring 201 assists in supporting the glue delivery barrel 2 on the platform scale 1. A top cover 3 is fixed to the upper portion of the outer circumference of the glue barrel 2, and the top end of the glue barrel 2 is closed by the top cover 3. A vent pipe 304 is fixedly connected to the center of the top end of the top cover 3, and a hollow rubber ball 305 is fixedly connected to the top end of the vent pipe 304. The hollow rubber ball 305 is connected to the glue barrel 2 through the vent pipe 304, so that when working, when the glue content in the glue barrel 2 changes, air will not enter or exit, thereby reducing the solidification of the glue in the glue barrel 2 due to solvent evaporation. A glue storage barrel 4 is provided above one side of the glue barrel 2, and the used glue is stored through the glue storage barrel 4.

[0026] Specifically, a push switch 102 is fixed at the center of the top of the platform scale 1 in the movable sleeve 101, and a pressure rod 202 is fixed at the center of the bottom end of the glue barrel 2. The bottom end of the pressure rod 202 corresponds to the position of the push switch 102. When the glue in the glue barrel 2 is pressed down by gravity, the compression spring 201 is compressed. When the compression spring 201 is compressed, the pressure rod 202 is pressed onto the push switch 102, so that the electric control valve 402 is closed during operation. When the glue content in the glue barrel 2 decreases, the compression spring 201 is lifted, the pressure rod 202 leaves the push switch 102, the push switch 102 is released, and the electric control valve 402 is started to replenish the glue in the glue barrel 2.

[0027] Furthermore, the compression spring 201 is arranged in the movable sleeve 101 and outside the compression rod 202 , so that the compression spring 201 maintains the position of the glue delivery barrel 2 above the platform scale 1 when working.

[0028] Furthermore, a return pipe 302 is fixedly connected to the top of the top cover 3 on one side of the vent pipe 304, and a glue delivery pipe 303 is fixed vertically through the return pipe 302 on the side away from the vent pipe 304. The bottom end of the glue delivery pipe 303 is arranged in the lower part of the glue delivery barrel 2, and the top end of the return pipe 302 is connected to the return end of the thin film glue coating equipment, so that after the thin film glue coating equipment coats the glue, it is refluxed into the glue delivery barrel 2, and the top end of the glue delivery pipe 303 is connected to the equipment for pumping the glue, so that the glue in the glue delivery barrel 2 is transported to the thin film glue coating equipment.

[0029] The operation process of this embodiment is as follows: during operation, the glue in the glue barrel 2 is pumped into the film gluing device through an external glue pumping device, and after being used in the film gluing device, it flows back to the glue barrel 2 through the reflux pipe 302. When the glue content in the glue barrel 2 changes, the hollow rubber ball 305 is connected to the glue barrel 2 through the vent pipe 304, so that when the glue content in the glue barrel 2 changes during operation, air will not enter or exit, thereby reducing the solidification of the glue in the glue barrel 2 due to solvent evaporation.

The feeding on and off of the feeding hose 401 is controlled by the electric control valve 402.

[0031] Specifically, based on the first embodiment, a fixing hole 301 is vertically opened at the top of the top cover 3 on the side of the vent pipe 304 away from the return pipe 302. The fixing hole 301 is set in the feeding hose 401, and the top cover 3 is connected to the vent pipe 304 through the fixing hole 301.

[0032] The operating process of this embodiment is as follows: when working, the glue in the glue storage barrel 4 is first transported to the glue delivery barrel 2 through the feeding hose 401 on the glue storage barrel, so that the weight of the glue delivery barrel 2 increases, and the glue delivery barrel 2 presses the compression spring 201 downward, so that the pressure rod 202 is pressed onto the push switch 102 on the scale 1, so that the push switch 102 is pressed down, and the electric control valve 402 closes the feeding hose 401. During operation, when the glue content in the glue delivery barrel 2 decreases, the compression spring 201 is lifted, the pressure rod 202 leaves the push switch 102, the push switch 102 is released, and the electric control valve 402 is started. At this time, the glue in the glue storage barrel 4 is transported to the glue delivery barrel 2 through the feeding hose 401 to replenish the glue in the glue delivery barrel 2.
