Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive production, in particular to a shearing device for hot melt adhesive. Background Technique

[0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, belonging to an environment-friendly chemical product. Because the hot melt adhesive product itself is solid, it is convenient for packaging, transportation, storage, solvent-free, pollution-free, non-toxic, and has the advantages of simple production process, high added value, large bonding strength and fast speed, so it is very popular. When producing hot melt adhesive, the hot melt adhesive is extruded into strips through an extrusion device. After forming, the strip-shaped hot melt adhesive still needs to be cut into the required length. When cutting the strip-shaped hot melt adhesive, a shearing device is correspondingly needed. In order to prevent the strip-shaped hot melt adhesive from shifting during movement, a structure for limiting the strip-shaped hot melt adhesive is arranged on the shearing device. However, at present, the width of the structure for limiting the strip-shaped hot melt adhesive on the shearing device cannot be adjusted, and the sizes of the strip-shaped hot melt adhesives are different, so there are inconveniences in the use process. Therefore, we propose a shearing device for hot melt adhesive to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0024] Embodiment

[0025] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a shearing device for hot melt adhesive proposed in an embodiment of the present utility model includes a bottom plate 1. Two mounting seats 19 are fixed on the top of the bottom plate 1. Two mounting holes are respectively opened at the bottom of the mounting seats 19, which makes it more convenient to operate when installing the bottom plate 1 at a suitable position. Two cross plates 2 are fixed at the bottom of the bottom plate 1. Two support rods 3 are fixed between the two cross plates 2. The surfaces of the two support rods 3 are slidably connected with eight side baffles 4. Elastic bands 17 are equidistantly fixed between adjacent two side baffles 4, which is convenient for blocking the strip-shaped through groove opened at the top of the bottom plate 1, avoiding the collision between the strip-shaped hot melt adhesive and the strip-shaped through groove during the movement. The side baffles 4 all slidably penetrate through the bottom plate 1 and extend above it. A first cylinder 5 is fixed at the bottom of the bottom plate 1. The ejecting end of the first cylinder 5 is fixed with a moving plate 6. U-shaped blocks 7 are respectively fixed at the bottom of the side baffles 4. The U-shaped blocks 7 all slidably penetrate through the bottom plate 1 and extend below it and are rotatably connected with a connecting rod 8 through a pin shaft. The other ends of the connecting rods 8 are respectively rotatably connected with the moving plate 6 through a pin shaft. Two brackets 9 are fixed on the top of the bottom plate 1. Second cylinders 10 are respectively fixed on the top of the brackets 9. The ejecting end of the left second cylinder 10 slidably penetrates through the corresponding bracket 9 and extends below it and is fixed with a U-shaped plate 11. A feeding roller 12 is rotatably connected between the inner walls on both sides of the U-shaped plate 11 through a bearing. An annular anti-slip rubber sleeve 18 is fixed on the surface of the feeding roller 12, which can increase the friction between the feeding roller 12 and the surface of the strip-shaped hot melt adhesive, so as to facilitate the feeding of the strip-shaped hot melt adhesive. The ejecting end of the right second cylinder 10 slidably penetrates through the corresponding bracket 9 and extends below it and is fixed with a sliding plate 13. A cutting knife 14 is fixed at the bottom of the sliding plate 13. A sinking groove for making way for the cutting knife 14 is opened on the top of the bottom plate 1. A limiting component 15 is arranged on the top of the sliding plate 13. When using this hot melt adhesive shearing device, after installing it at a suitable position, one end of the extruded strip-shaped hot melt adhesive can pass through the lower part of the feeding roller 12 and be placed between the corresponding two side baffles 4. Then start the left second cylinder 10 to drive the U-shaped plate 11 to move downwards. After the U-shaped plate 11 moves downwards, it will drive the feeding roller 12 to move downwards. When the feeding roller 12 moves downwards and fits with the strip-shaped hot melt adhesive, the feeding of the strip-shaped hot melt adhesive can be carried out. When it needs to be cut after being fed to a suitable length, start the right second cylinder 10 to drive the sliding plate 13 to move downwards. After the sliding plate 13 moves downwards, it will drive the cutting knife 14 and the limiting component 15 to move downwards. At this time, the limiting component 15 first contacts the strip-shaped hot melt adhesive and limits it, and then the downward moving cutting knife 14 can cut the strip-shaped hot melt adhesive. Finally, the cut strip-shaped hot melt adhesive can slide down along the inclined plate of the bottom plate 1 for collection.

[0026] As Figure 6As shown in the figure, there is another structure for the limiting component 15 provided at the top of the sliding plate 13 in the present utility model. It mainly includes two U-shaped rods 20 slidably penetrating through the sliding plate 13. At the bottom ends of the U-shaped rods 20, pressing plates 21 are fixedly provided. Elastic pads 22 are fixedly provided at the bottoms of the pressing plates 21. Second springs 23 are fixedly provided at the tops of the pressing plates 21. The top ends of the second springs 23 are fixedly connected to the inner wall of the top of the sliding plate 13. When in use, when the sliding plate 13 moves downward, it will drive the U-shaped rods 20 to move downward. After the U-shaped rods 20 move, they will drive the pressing plates 21 to move downward to contact the strip-shaped hot melt adhesive. When continuing to move downward, the second springs 23 will be in a compressed state. Therefore, it can realize pressing and limiting the strip-shaped hot melt adhesive, and the elastic pads 22 can play a role in protecting the hot melt adhesive strip to avoid damaging its surface.

[0027] As Figure 5 shown, in some embodiments, the limiting component 15 includes four guide rods 1501 slidably penetrating through the top of the sliding plate 13. At the bottom ends of the two corresponding guide rods 1501, limiting plates 1502 are fixedly provided. Rubber pads 1503 are fixedly provided at the bottoms of the limiting plates 1502. Two first springs 1504 are fixedly provided at the tops of the limiting plates 1502. The top ends of the first springs 1504 are fixedly connected to the inner wall of the top of the sliding plate 13. When in use, when the sliding plate 13 moves downward, it will drive the guide rods 1501 to move downward. After the guide rods 1501 move, they will drive the limiting plates 1502 to move downward to contact the strip-shaped hot melt adhesive. When it continues to move downward, the first springs 1504 will be in a compressed state. Therefore, it can realize pressing and limiting the strip-shaped hot melt adhesive, and the rubber pads 1503 can play a role in protecting the hot melt adhesive strip to avoid the limiting plates 1502 damaging its surface.

[0028] As Figure 1 shown, in some embodiments, two T-shaped rods 16 slidably penetrate through the tops of the two brackets 9. The bottom ends of two of the T-shaped rods 16 are fixedly connected to the U-shaped plate 11, and the bottom ends of the other two T-shaped rods 16 are fixedly connected to the sliding plate 13, which can play a role in guiding and supporting the U-shaped plate 11 and the sliding plate 13, so that they will be more stable during the up and down movement process.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
