Description

Technical Field

[0001] The utility model relates to the technical field of EPE board production, in particular to a new type of EPE board cutting machine table. Background Technique

[0002] EPE is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene resin. It overcomes the disadvantages of ordinary foaming glue, such as being fragile, deformed, and having poor restorability. It has many advantages, such as water-proof, moisture-proof, shock-proof, sound-insulating, heat-insulating, good plastic properties, strong toughness, recyclable, environmentally friendly, and strong impact resistance. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.

[0003] In the existing EPE board cutting machine table, during the cutting process, the EPE board is manually pushed under the cutting machine and then cut, which easily causes the EPE board to wrinkle and bend, resulting in the offset of the cutting surface after the EPE board is cut, affecting the cutting efficiency.

[0004] Therefore, we propose a new type of EPE board cutting machine table. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of EPE board cutting machine table to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A new type of EPE board cutting machine table, including a workbench, a support frame is fixedly installed in the middle of the top of the workbench, an electric push rod is fixedly installed on the top of the support frame, a lifting plate located inside the support frame is fixedly installed at the movable end of the bottom of the electric push rod, a fixed frame is fixedly installed in the middle of the bottom of the lifting plate, rotating seats are fixedly installed on both sides of the fixed frame at the bottom of the lifting plate, a cutting knife is fixedly installed at the bottom of the fixed frame, tension springs are fixedly installed on both sides of the fixed frame, a connecting long rod is rotatably connected in the middle of the rotating seat, swing rods are fixedly installed at both ends and in the middle of the connecting long rod, limiting blocks in abutting contact are arranged on the outer peripheral surface of the connecting long rod and on both sides of the rotating seat, a rotating rod is rotatably connected to the bottom of the swing rod, a roller is fixedly installed on the outer peripheral surface of the rotating rod, and the other end of the tension spring is fixedly installed with the swing rod.

[0007] Optionally, an activity groove is opened in the middle of the swing rod in the middle, a threaded sleeve is threadedly connected through the top of the activity groove, a sliding rod is slidably connected through the middle of the threaded sleeve, a knob located inside the activity groove is fixedly installed at the bottom of the outer peripheral surface of the threaded sleeve, a pressing spring is sleeved in the middle of the sliding rod, a pressing rubber block is fixedly installed at the bottom of the sliding rod, and the bottom of the pressing rubber block is in abutting contact with the outer peripheral surface of the rotating rod.

[0008] Optionally, both sides of the pressing rubber block are in sliding contact with the inside of the movable groove. The top of the pressing spring is in pressing contact with the bottom of the knob, and the bottom of the pressing spring is in pressing contact with the top of the pressing rubber block.

[0009] Optionally, a cutting groove is formed in the middle of the top of the workbench, and the cutting groove is located directly below the cutting knife.

[0010] Optionally, the limiting blocks integrally provided on the connecting long rod are located on both sides of the rotating seat, and the maximum included angle between the swing rod and the lifting plate is 75 degrees.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the novel EPE board cutting machine table, by providing the swing rod and the roller, after the EPE board is fed under the cutting knife, the electric push rod pushes the lifting plate to descend. The roller first contacts the top of the EPE board. As the lifting plate descends, the roller rolls on the EPE board. At the same time, the swing rod rotates around the connecting long rod, so that the roller spreads out the wrinkled EPE board and tightens the EPE board. When cutting, the situation of skewing will not occur, and the cutting quality of the EPE board can be always guaranteed. At the same time, the cutting effect on the EPE board is also improved.

[0015] In the novel EPE board cutting machine table, by providing the movable groove and the pressing rubber block, by rotating the knob, the height of the bottom of the threaded sleeve is changed, and then the distance between the knob and the pressing rubber block is changed. Further, the compression amount of the pressing spring is changed, so that the acting force of the pressing spring on the pressing rubber block is changed. Further, the frictional force between the pressing rubber block and the rotating rod is changed. When the frictional force between the roller and the EPE board is less than the frictional force between the pressing rubber block and the rotating rod, the EPE board is stretched. When the frictional force between the roller and the EPE board is greater than the frictional force between the pressing rubber block and the rotating rod, the roller can rotate, preventing the EPE board from being broken due to excessive frictional force.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4, the present utility model provides a new type of EPE board cutting machine table, including a workbench 1. In the middle of the top of the workbench 1, a support frame 2 is fixedly installed. On the top of the support frame 2, an electric push rod 3 is fixedly installed. The movable end at the bottom of the electric push rod 3 is fixedly installed with a lifting plate 4 located inside the support frame 2. In the middle of the bottom of the lifting plate 4, a fixed frame 5 is fixedly installed. On both sides of the fixed frame 5 at the bottom of the lifting plate 4, rotating seats 7 are fixedly installed. At the bottom of the fixed frame 5, a cutting knife 6 is fixedly installed. On both sides of the fixed frame 5, tension springs 9 are fixedly installed. In the middle of the rotating seat 7, a connecting long rod 8 is rotatably connected. At both ends and in the middle of the connecting long rod 8, swing rods 10 are fixedly installed. On the outer peripheral surface of the connecting long rod 8 and on both sides of the rotating seat 7, limiting blocks 11 in abutting contact are provided. At the bottom of the swing rod 10, a rotating rod 12 is rotatably connected. On the outer peripheral surface of the rotating rod 12, a roller 13 is fixedly installed. The other end of the tension spring 9 is fixedly installed with the swing rod 10. By providing the swing rod 10 and the roller 13, after the EPE board is fed under the cutting knife 6, the electric push rod 3 pushes the lifting plate 4 to descend. The roller 13 first contacts the top of the EPE board. As the lifting plate 4 descends, the roller 13 rolls on the EPE board. At the same time, the swing rod 10 rotates around the connecting long rod 8, so that the roller 13 spreads out the wrinkled EPE board and tightens the EPE board. When cutting, the situation of skew will not occur, and the cutting quality of the EPE board can be always guaranteed. At the same time, the cutting effect on the EPE board is also improved.

[0023] In the middle of the swing rod 10 located in the middle, an activity groove 14 is provided. At the top of the activity groove 14, a threaded sleeve 15 is threadedly connected through. In the middle of the threaded sleeve 15, a sliding rod 16 is slidably connected through. At the bottom of the outer peripheral surface of the threaded sleeve 15, a knob 17 located inside the activity groove 14 is fixedly installed. In the middle of the sliding rod 16, a tightening spring 19 is sleeved. At the bottom of the sliding rod 16, a tightening rubber block 18 is fixedly installed. The bottom of the tightening rubber block 18 is in abutting contact with the outer peripheral surface of the rotating rod 12. Both sides of the tightening rubber block 18 are in sliding contact with the inside of the activity groove 14. The top of the tightening spring 19 is in abutting contact with the bottom of the knob 17. The bottom of the tightening spring 19 is in abutting contact with the top of the tightening rubber block 18. By providing the activity groove 14 and the tightening rubber block 18, by rotating the knob 17, the height at the bottom of the threaded sleeve 15 is changed, and then the distance between the knob 17 and the tightening rubber block 18 is changed. Further, the compression amount of the tightening spring 19 is changed, so that the acting force of the tightening spring 19 on the tightening rubber block 18 is changed. Further, the frictional force between the tightening rubber block 18 and the rotating rod 12 is changed. When the frictional force between the roller 13 and the EPE board is less than the frictional force between the tightening rubber block 18 and the rotating rod 12, the EPE board is stretched. When the frictional force between the roller 13 and the EPE board is greater than the frictional force between the tightening rubber block 18 and the rotating rod 12, the roller 13 can rotate, preventing the EPE board from breaking due to excessive frictional force.

[0024] In the middle of the top of the workbench 1, a cutting groove 20 is provided, and the cutting groove 20 is directly below the cutting knife 6. The limiting blocks 11 integrally provided on the connecting long rod 8 are located on both sides of the rotating seat 7. The maximum included angle between the swing rod 10 and the lifting plate 4 is seventy-five degrees. The bottom of the roller 13 is lower than the bottom of the cutting knife 6. A rotating rod 12 is sleeved with two rollers 13, and the two rollers 13 are located between two adjacent swing rods 10. Chute grooves are provided on the front and rear sides of the support frame 2. The front and rear ends of the lifting plate 4 are integrally connected with convex blocks, and the convex blocks of the lifting plate 4 are slidably connected to the inside of the chute grooves.

[0025] Working principle:

[0026] By rotating the knob 17, the height at the bottom of the threaded sleeve 15 is changed, and then the distance between the knob 17 and the abutting rubber block 18 is changed. Further, the compression amount of the abutting spring 19 is changed, so that the acting force of the abutting spring 19 on the abutting rubber block 18 is changed, and further the frictional force between the abutting rubber block 18 and the rotating rod 12 is changed. After the EPE board is fed under the cutting knife 6, the electric push rod 3 pushes the lifting plate 4 to descend. The roller 13 first contacts the top of the EPE board. As the lifting plate 4 descends, the roller 13 rolls on the EPE board. When the frictional force between the roller 13 and the EPE board is less than the frictional force between the abutting rubber block 18 and the rotating rod 12, the EPE board is stretched. When the frictional force between the roller 13 and the EPE board is greater than the frictional force between the abutting rubber block 18 and the rotating rod 12, the roller 13 can rotate, preventing the EPE board from breaking due to excessive frictional force. At the same time, the swing rod 10 rotates around the connecting long rod 8, so that the roller 13 spreads out the wrinkled EPE board and tensions the EPE board, and the situation of skew will not occur during cutting.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
