Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape gluing equipment, in particular to a gluing equipment for adhesive tape processing. Background Art

[0002] The production and processing of adhesive tape is to apply adhesive on plastic film, paper, cloth and other substrates, and make a tape product with adhesive function through a certain processing technology. In the production and processing of adhesive tape, dipping is a key step, which is usually to soak the tape in glue to glue the tape.

[0003] At present, the existing dipping method usually adopts a static dipping method, adding glue into the box body, and then controlling the tape to pass through the glue, so as to achieve the effect of coating the tape. However, during the dipping process, the glue will continue to decrease. As the glue decreases, some glue will adhere to the inner wall of the box body. If this part of the glue is not processed, it will solidify on the side wall of the box body, and the subsequent cleaning is more cumbersome. In addition, during the dipping process, since the glue above is basically in a static state and is in contact with the air for a long time, the cooling speed is relatively fast, and a layer of flocs is easily solidified on the surface. At this time, if the flocs are attached to the tape, it is difficult to fully and evenly immerse it during dipping, affecting the processing of the tape. Summary of the invention

[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] A gluing device for adhesive tape processing, comprising a box 1 with an open top:

[0024] A bottom plate 2 that can move up and down is arranged at the bottom of the box body 1, wherein the bottom plate 2 is connected to the bottom wall of the box body 1 through a water bag 3, and the water bag 3 is connected to the water tank 5 outside the box body 1 through a hose 4, and a waterproof cloth 6 is arranged on the top of the bottom plate 2, and the edge of the waterproof cloth 6 is bent upward and the top end thereof is bonded and fixed to the corresponding inner wall of the box body 1, and a contraction mechanism 7 is arranged in the waterproof cloth 6, and two groups of transmission rollers 8 are arranged in parallel in the box body above the waterproof cloth 6, wherein support rollers 9 are arranged on both sides of the top of the box body 1 above the two groups of transmission rollers 8, and a cleaning mechanism 10 and a circulation mechanism 11 are respectively arranged on the inner and outer sides of the box body 1 between the transmission rollers 8 and the support rollers 9, and a dust removal mechanism 12 is arranged in the box body 1 between one group of transmission rollers 8 and the corresponding support rollers 9;

[0025] The cleaning mechanism 10 includes an electromagnet 1101 disposed on both side walls of the box body 1, a circle of skirt 102 is disposed in the box body 1 below the electromagnet 1101 and abuts against the inner wall thereof, a metal frame 103 magnetically connected to the electromagnet 1101 is disposed in the opening of the skirt 102, and the metal frame 103 is fixedly connected to the skirt 102 via a connecting block 104;

[0026] The circulation mechanism 11 includes an overflow box 111 arranged on the outer side walls at both ends of the box body 1, and the top of the side wall of the overflow box 111 is provided with an overflow port 112 connected to the box body 1, and the bottom of the side wall of the overflow box 111 is provided with a one-way liquid outlet pipe 113 connected to the box body 1. The overflow box 111 is also provided with a baffle 114 driven by an electric push rod 115, and the baffle 114 is composed of a strip plate I1141 and a strip plate II1142. The strip plate I1141 and the bottom of the strip plate II1142 are hinged by a hinge 1143, and the strip plate I1141 is provided with an electromagnet II1144 located above the strip plate II1142 and in contact with it.

[0027] like Figure 4 As shown, the baffle 114 divides the overflow box 111 into two parts, the internal opening height of the overflow box 111 above the overflow port 112 is greater than the thickness of the baffle 114, the overflow port 112 is located above the metal frame 103, the output shaft of the electric push rod 115 is connected and fixed to the top of the strip plate I1141, and a baffle 13 is provided on one side of the bottom of the strip plate I1141 on the same side as the strip plate II1142.

[0028] In this embodiment, the straight line formed by the two groups of overflow boxes 111 and the straight line formed by the two groups of water tanks 5 are vertically intersected, and the top of the water tank 5 is flush with the top of the overflow box 111.

[0029] The one-way liquid outlet pipe 113 is located below the transmission roller 8, and an L-shaped plate 14 for fixing the two ends of the corresponding transmission roller 8 is arranged in the opening of the metal frame 103. The horizontal end of the L-shaped plate 14 extends to the outside of the top of the box body 1 and is fixedly connected to the top surface of the box body 1 by bolts. A rotating shaft 15 fixed to the vertical end of the L-shaped plate 14 by a bearing is arranged at the end of the transmission roller 8. A motor 16 is arranged on the top of the L-shaped plate 14, and sprockets are arranged on the output shaft of the motor 16 and the end of the corresponding rotating shaft 15, wherein the upper and lower corresponding groups of sprockets are connected by a chain 17. A rectangular tube 18 fixedly connected to the side wall of its vertical end is vertically arranged on the horizontal end of the L-shaped plate 14, and the rectangular tube 18 is located in the opening of the metal frame 103, and the chain 17 passes through the inner opening of the rectangular tube 18. When the motor 16 drives the product on the driving roller 8 to move through the sprocket, chain 17 and shaft 15, since the above components are all located in the opening of the metal frame 103, they will not affect the normal up and down movement of the metal frame 103 in the box body 1.

[0030] The waterproof cloth 6 is bonded and fixed to the bottom plate 2 at the middle area of ​​the bottom. The shrinkage mechanism 7 includes a protrusion 71 arranged at the middle of the bottom of the waterproof cloth 6. The outer wall of the protrusion 71 is inclined upward and provided with an elastic rope 72 connected to the bending part of the edge of the waterproof cloth 6.

[0031] In this embodiment, the upper and lower end surfaces of the water bag 3 are respectively bonded and fixed to the corresponding bottom plate 2 and the inner bottom wall of the box body 1. A limiting column 19 is arranged at the bottom of the water bag 3, and a limiting tube 20 is arranged at the top of the water bag 3 and is sheathed on the limiting column 19.

[0032] The dust removal mechanism 12 includes a strip box body 121 longitudinally arranged at the top of the box body 1, and the box body 121 is located above the overflow port 112. The upper and lower side walls of the box body 121 are provided with strip openings 122, and cleaning rollers 123 driven by a driving mechanism are respectively arranged in the box body 121 on both sides of the straight line formed by the two groups of strip openings 122, and flexible bristles 124 are arranged on the outer side walls of the cleaning roller 123. Dust suction pipes 125 connected to the exhaust fan through pipes are also arranged on both sides of the bottom of the box body 121, and suction holes are evenly arranged on the side walls of the dust suction pipe 125.

[0033] The working principle of the present invention is as follows: when in use, the glue is heated in the box 1 and heated by the heating wire, wherein the adhesive tape is stretched by the supporting roller 9 and the driving roller 8, and at this time, the motor 16 drives the product on the driving roller 8 to move and transport it through the sprocket, chain 17 and rotating shaft 15, so that the glue is applied on the adhesive tape;

[0034] like Figure 1 As shown, the cleaning roller 123 is rotated to drive the bristles 124 to clean the end surface of the tape, and at the same time, the dust and other impurities obtained by cleaning and diffused in the box body 121 are extracted through the exhaust fan, the dust suction pipe 125 and the suction hole, thereby achieving the purpose of pre-treatment of the tape, so as to facilitate the subsequent gluing work;

[0035] In the above process, due to the squeezing effect of the weight of the glue in the box 1 above the waterproof cloth 6, it will squeeze the liquid in the water bag 3 through the bottom plate 2, so that the liquid flows into the water tank 5 through the hose 4, thereby causing the water bag 3 to shrink and the bottom plate 2 to move down. At this time, a large amount of glue can be loaded in the box 1. When the amount of glue in the box 1 gradually decreases due to the gluing of the tape, the gradual decrease in the amount of glue in the box 1 will cause the squeezing force on the water bag 3 through the bottom plate 2 to decrease accordingly. Then, under the squeezing of the gravity of the liquid in the water tank 1, the liquid will slowly be injected into the water bag 3 through the hose 4 to make it slowly stretch. When the water bag 3 slowly stretches, the waterproof cloth 6 will be lifted up through the bottom plate 2 to push the glue above it to move upward, preventing the glue level in the box 1 from dropping so that the glue can always soak the tape inside the box 1. The reason why an elastic member such as a spring is not provided under the bottom plate 2 to replace the water bag 3 in this embodiment is that the elastic member is prone to mechanical fatigue after long-term use, which eventually affects the use.

[0036] Because the glue in the upper part of the box body 1 is far away from the bottom heating position and in contact with the air, it cools quickly and is easy to flocculate. When the waterproof cloth 6 is pushed upward by the bottom plate 2 to push the glue liquid level up, it will push the liquid level over the overflow port 112, so that the flocculated matter and the excess glue on the top of the box body 1 will overflow the overflow port 112 and enter the overflow box 111 above the baffle 114. Of course, the liquid in the water tank 1 can also be pushed into the water bag 3 to stretch it through forced human intervention, and then the glue level in the box body 1 above it can be pushed over the overflow port 112 through the bottom plate 2. At this time, the electric push rod 115 pushes the baffle plate 114 downward and sucks the excess glue and floccules in the box body 1 through the overflow port 112, so that the excess glue and floccules quickly enter the overflow box 111 through the overflow port 112, preventing the floccules from floating in the middle of the top of the box body 1 and not easily flowing into the overflow box 111 with the glue. When the excess glue and floccules enter the overflow box 111, the electromagnet II1144 is powered off, so that the strip plate I1141 will not be sucked by the electromagnet II1144 to the strip plate II1142. The glue on the baffle 114 will exert a gravity squeeze on the strip plate II1142, so that the strip plate II1142 rotates with the hinge 1143 as the center. At the same time, the rotation angle of the strip plate II1142 is limited by the baffle 13. Then, the glue on the baffle 114 will flow downward through the gap between the inclined strip plate II1142 and the side wall of the overflow box 111. When the liquid above it is drained, the magnetic attraction generated by the operation of the electromagnet II1144 will guide the strip plate II1142. The hinge 1143 is rotated upward, and finally the strip plate II1142 is magnetically connected with the electromagnet II1141, so that the strip plate I1141 and the strip plate II1142 form a baffle 114 in a horizontal state. In the above process, a heating wire is arranged in the overflow box 111 to heat the glue and flocculants inside it to prevent flocculants. Then the electric push rod 115 drives the baffle 114 to move downward to push the glue in the overflow box 111 to be forcibly introduced into the box body 1 through the one-way liquid outlet pipe 113 for recycling.

[0037] When in use, the electromagnet 1101 can be powered off. Then, when the magnetic fixing force on the metal frame 103 is lost, the skirt 102 moves downward under the gravity of the metal frame 103 and the skirt 102 to scrape and clean the adhesions on the inner wall of the box body 1. When it is necessary to drive the metal frame 103 and the skirt 102 upward, the magnetic attraction force generated by the electromagnet 1101 exerts an upward pulling force on the metal frame 103, and the one-way liquid outlet tube 113 discharges glue and exerts an upward pushing force on the metal frame 103. The metal frame 103 drives the skirt 102 upward to scrape the inner wall of the box body 1, and finally the metal frame 103 contacts the electromagnet 1101 so that the two are magnetically fixed.

[0038] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
