Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable tape processing technology, and in particular to a hot melt cutting device for hot melt adhesive on the edge of heat shrinkable tape. Background Technology

[0002] Radiation-crosslinked polyethylene (RCPE) heat-shrinkable tape is a strip material composed of a radiation-crosslinked polyethylene (RCPE) substrate and a hot melt adhesive. The substrate is a crosslinked polyethylene material irradiated with high-energy particles. Compared to ordinary polyethylene, it possesses higher mechanical strength, better resistance to heat aging, chemical corrosion, environmental stress cracking, and ultraviolet radiation, and has a longer service life. The hot melt adhesive exhibits high bonding strength and good resistance to high and low temperatures.

[0003] The first step in the production of heat shrinkable tape is to heat and plasticize the polyolefin material, extrude it, crosslink it through high-energy electron beam radiation, and then coat the inner layer with hot melt adhesive. When coating the adhesive layer, in order to ensure that the inner surface of the heat shrinkable tape substrate is fully coated with hot melt adhesive and the thickness is uniform, the coating width of the hot melt adhesive must be greater than the width of the substrate. In order to ensure the appearance of the heat shrinkable tape substrate after coating, the excess heat shrinkable tape substrate on both sides needs to be trimmed.

[0004] The existing trimming devices are all in relatively fixed positions, making it inconvenient to adjust their positions at any time to trim the edges of shrink tape of different sizes, resulting in low practicality.

[0005] Therefore, it is necessary to provide a hot melt cutting device for the edge hot melt adhesive of heat shrinkable tape to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

Figure 4 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 6 for Figure 3The enlarged schematic diagram of section C is shown. The hot melt cutting device for the edge hot melt adhesive of the heat shrinkable tape includes: a conveying device 1, on which the shrinkable tape 7 is uniformly conveyed on the inner wall of the top of the conveying device 1; pushing components 8 are installed on the front and rear sides of the top of the conveying device 1; the pushing components 8 are connected to a rectangular plate 3; rectangular groove 9 is opened on the front and rear sides of the top of the rectangular plate 3; rectangular groove 10 and rectangular groove 12 are opened at the center of the top of the rectangular plate 3; a driving component 11 is installed on the inner wall of rectangular groove 10; a moving component 13 is installed on the inner wall of rectangular groove 12; the moving component 13 is connected to the driving component 11; a limiting component 6 is connected to the moving component 13; two sets of mounting plates 5 are connected to the limiting component 6; a cutting component 4 is installed on the top of each of the two sets of mounting plates 5; and the mounting plates 5 are located inside the rectangular groove 9.

[0018] Preferably, the pushing component 8 includes a second cylinder 81 and a slider 83. The second cylinder 81 is fixed to the rear side of the top of the conveying device 1. The top front and rear sides of the conveying device 1 are provided with grooves 82. The inner walls of the two sets of grooves 82 are in close contact with the two sets of sliders 83. The output end of the second cylinder 81 is fixedly connected to the outer right side of one set of sliders 83. The corresponding sides of the two sets of sliders 83 are fixedly connected to the rectangular plate 3.

[0019] The output end of cylinder 2 81 pushes the slider 83 connected to it, thereby causing the rectangular plate 3 to move above the shrinkage belt 7, so that the cutting component 4 can cut the edge of the shrinkage belt.

[0020] The drive assembly 11 includes a motor 111, which is fixed to the inner wall of the second rectangular slot 10. The output end of the motor 111 extends into the interior of the third rectangular slot 12, and a second bevel gear 113 is fixedly installed at the output end of the motor 111. The moving assembly 13 is connected to a first bevel gear 112, which meshes with the second bevel gear 113.

[0021] When the output end of motor 111 drives bevel gear 113 to rotate, bevel gear 113 will drive the moving component 13 to run through bevel gear 112.

[0022] The moving component 13 includes a bidirectional threaded rod 132. The front and rear ends of the bidirectional threaded rod 132 are rotatably connected to the inner walls of two sets of rectangular grooves 9, and the bidirectional threaded rod 132 passes through rectangular groove 3 12 and is rotatably connected to rectangular groove 3 12. A bevel gear 2 113 is fixedly installed on the outer wall of the bidirectional threaded rod 132 located inside the rectangular groove 3 12. Threaded blocks 133 are threadedly connected to both the front and rear ends of the bidirectional threaded rod 132.

The left side of the two sets of threaded blocks 133 is connected to the limiting component 6.

[0023] When bevel gear 113 drives bevel gear 112 to rotate, the bidirectional threaded rod 132 drives two sets of threaded blocks 133 to move relative to each other along the guide rod 131, so that the limiting component 6 moves inside the rectangular groove 9.

[0024] The limiting component 6 includes a limiting plate 61. Two sets of limiting plates 61 are fixedly connected to the side walls of two sets of threaded blocks 133 respectively. Each set of limiting plates 61 has a sliding groove 62 on the side away from the center of the conveying device 1. The top of the limiting plate 61 is fixedly connected to the mounting plate 5. The sliding groove 62 is connected to the cutting component 4.

[0025] The two sets of threaded blocks 133 drive the two sets of limiting plates 61 to move relative to each other at the same time, thereby positioning the limiting plates 61 to the position where the shrink tape 7 needs to be cut according to the cutting requirements.

[0026] The cutting assembly 4 includes a cylinder 41, which is fixed to the top of the mounting plate 5. The output end of the cylinder 41 extends through to the bottom of the mounting plate 5, and a connecting plate 42 is fixedly installed at the output end of the cylinder 41. The other end of the connecting plate 42 is movably connected to the inner wall of the slide groove 62, and a blade 43 is fixedly installed at the end of the connecting plate 42. The blade 43 is in close contact with the side wall of the limiting plate 61.

[0027] When the limiting plate 61 moves to the position where the shrink tape 7 needs to be cut, the output end of the cylinder 41 pushes the connecting plate 42 so that the blade 43 automatically cuts the shrink tape 7.

[0028] A control device 2 is fixedly installed on the side wall of the conveying device 1. The control device 2 is electrically connected to the motor 111 and the cylinder 41 respectively. The control device 2 is a PLC controller.

[0029] The working principle of the hot melt cutting device for the edge hot melt adhesive of the heat shrink tape provided by this utility model is as follows: After the conveying device 1 moves the shrink tape 7 to be cut to the cutting position, the driving component 11 will drive the moving component 13 to run, so that the moving component 13 will drive the limiting component 6 and the mounting plate 5 to move inside the rectangular groove 9. When the limiting component 6 drives the mounting plate 5 to the cutting position, the cutting component 4 will accurately cut off the edge of the shrink tape 7 under the positioning of the limiting component 6.

[0030] Compared with related technologies, the hot melt cutting device for the edge hot melt adhesive of the heat shrinkable tape provided by this utility model has the following beneficial effects: When the output end of motor 111 drives bevel gear 113 to rotate, bevel gear 113 will drive the bidirectional threaded rod 132 to rotate through bevel gear 112. The bidirectional threaded rod 132 drives two sets of threaded blocks 133 to move relative to each other along guide rod 131, so that the two sets of threaded blocks 133 drive two sets of limiting plates 61 to move relative to each other at the same time. Thus, the limiting plate 61 is positioned at the position to be cut on the shrink tape 7 according to the cutting needs. Through the interaction of the above components, the edge of the shrink tape 7 can be freely positioned according to its size.
