Description

Technical Field

[0001] This invention relates to the field of polyethylene sheet cutting equipment technology, and in particular to a segmented cutting equipment for processing polyethylene sheets, a polymer material. Background Technology

[0002] Polyethylene sheet cutting equipment is a common type of equipment used to cut polyethylene sheets, a type of polymer material. In order to meet the needs of subsequent use of polyethylene sheets, cutting equipment is used to cut polyethylene sheets into sections according to specifications.

[0003] Existing technologies, such as CN113021437B, disclose a segmented cutting device for the production of polyethylene sheets, relating to the field of cutting equipment technology. This device solves the problem that existing segmented cutting devices mostly require manual operation of the top-pressing component to clamp and position the sheet during cutting, making operation cumbersome and inconvenient. The segmented cutting device for the production of polyethylene sheets includes a worktable, which includes limiting plates. Two limiting plates are symmetrically welded to the top of the worktable, and a support frame is welded and fixed at the middle of the top of the worktable. An electric push rod with a horizontal support is suspended at the middle of the bottom of the worktable, and a sliding groove is formed through the middle section of the worktable and the two limiting plates. This invention uses a row of teeth at the top of the support frame; when the slider slides left and right, it can engage with and drive the driven gear to rotate, providing the power for the saw blade to slide up and down for sawing. This eliminates the need for an additional drive motor for the saw blade.

[0004] The inventors discovered the following drawbacks of the cutting equipment when cutting polyethylene sheets into sections: First, after cutting the polyethylene sheets into sections, the operator needs to manually remove the cut polyethylene sheets from the workbench, which wastes a certain amount of labor; Second, each time the polyethylene sheet is cut into sections, the operator needs to measure the polyethylene sheet and then cut it, which is cumbersome and has a low degree of automation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a segmented cutting device for processing polyethylene sheets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a segmented cutting device for processing polyethylene sheets, comprising a pad, a support frame mounted on the upper surface of the pad, a drive wheel and a driven wheel respectively mounted on the upper end of the support frame, a conveyor belt drivingly connecting the arc surfaces of the drive wheel and the driven wheel, a fixed plate welded to the upper surface of the pad, a motor B fixedly connected to one side of the fixed plate, the output end of the motor B fixedly connected to the drive wheel, the fixed plate having an adjustment structure, the adjustment structure including a fixed shaft and a conveying assembly, the fixed shaft fixedly connected to the fixed plate, the conveying assembly including a collar, the collar rotatably connected to the arc surface of the fixed shaft, four arc blocks fixedly connected to one side of the collar, a reserved groove opened at one end of the fixed shaft, the size of the reserved groove being adapted to the gap size of the four arc blocks, a gear ring fixedly connected to one side of the collar, a motor fixedly connected to one side of the fixed plate, a gear fixedly connected to the output end of the motor, the gear meshing with the gear ring.

[0007] Using the above technical solution, the polyethylene sheet is placed directly in the gap between the four arc blocks. After the polyethylene sheet is cut, the motor can drive the gear to rotate, which in turn drives the gear ring and the collar to rotate. The arc blocks drive the polyethylene sheet to rotate. When the sheet rotates to connect with the pre-reserved groove of the fixed shaft, the cut polyethylene sheet can slide directly onto the conveyor belt, and the conveyor belt can be used to transfer the cut polyethylene sheet.

[0008] Preferably, the arc surface of the fixed shaft is fixedly connected to two connecting plates, and the two connecting plates are respectively fixedly connected to a feeding hopper and a receiving hopper. The included angle formed by the feeding hopper and the receiving hopper is 90°.

[0012] Preferably, a positioning frame is welded to one side of the feed hopper, and a conveying hopper is fixed to one end of the positioning frame. The end of the conveying hopper away from the feed hopper is a flared end.

[0014] Preferably, a limiting component for limiting the polyethylene plate is provided on one side of the conveying hopper. The limiting component includes a connecting frame, which is installed on one side of the conveying hopper by means of bolts. A cylinder is fixedly connected inside the connecting frame. A slot is opened on the side of the conveying hopper near the connecting frame. A pulley is fixedly connected to the output end of the cylinder.

[0015] By adopting this preferred solution, after the polyethylene sheet is placed in the conveying hopper, the pulley driven by the cylinder can be used to squeeze the polyethylene sheet, thereby limiting the movement of the polyethylene sheet during the conveying and cutting processes.

[0016] Preferably, the surface of the slip ring is provided with a measuring component for estimating the cutting length of the polyethylene sheet. The measuring component includes a rectangular hole, which is opened on the slip ring. A pointer is fixed to the inside of the rectangular hole, and a scale groove is provided on one side of the ear plate.

[0017] By adopting this preferred solution, the operator can easily observe the blade distance when the servo electric cylinder moves the blade position, thereby better controlling the cutting length of the polyethylene sheet.

[0018] Preferably, the lower end of the positioning frame is provided with a chip collection structure, the chip collection structure includes a connecting block, the connecting block is welded to the positioning frame, the lower end of the connecting block is fixedly connected to a connecting rod, the lower end of the connecting rod is welded to a sliding bucket, one end of the sliding bucket is slidably inserted with a collection box, the lower surface of the sliding bucket is fixedly connected to a buckle plate, the short arm end of the buckle plate is fixedly connected to a locking block, the locking block is a rubber block, the surface of the buckle plate is slidably fitted with a retaining ring, the upper end of the retaining ring is fixedly connected to the collection box.

[0019] Using the above technical solution, after cutting the polyethylene sheet with the cutting component, the waste generated from the cutting can be collected in a collection box. Operators only need to periodically move the collection box to transfer the waste.

[0020] Preferably, a filter plate is slidably inserted into the collection box, one end of the filter plate is fixedly connected to two elastic ropes, and the other end of the elastic ropes is fixedly connected to the collection box.

[0021] This preferred solution achieves the effect of separating and collecting waste and scrap materials.

[0022] Preferably, the upper surface of the pad is provided with an auxiliary structure, the auxiliary structure including a mounting plate, the mounting plate being fixed to the pad by bolts, a screw being rotatably connected to the upper end of the mounting plate, an adjusting block being threadedly connected to the arc surface of the screw, an adjusting frame being fixed to one side of the adjusting block, a limit wheel and a brush being fixed to the upper and lower sides of the inner side of the adjusting frame respectively, and the arc surface of the limit wheel being connected to the conveyor belt for transmission.

[0023] By adopting the above technical solution, the position of the limit wheel can be quickly adjusted to adjust the tightness of the conveyor belt, and a brush can be used to clean the small amount of debris and waste adhering to the surface of the conveyor belt.

[0024] Preferably, a guide rod is fixedly connected to the upper surface of the mounting plate, and the upper end of the guide rod slides through the adjusting block.

[0025] By adopting this preferred solution, the rotational position of the adjusting block can be restricted.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. In this invention, by setting an adjustment structure, the position of the motor A and its blade can be adjusted first with the help of the metering component, thereby adjusting the segmented cutting length of the polyethylene sheet. Then, the motor B is started, and the motor B drives the conveyor belt. After the polyethylene sheet is put into the feed hopper, the moving polyethylene sheet can be limited by the limiting component without affecting the normal conveying of the polyethylene sheet. After the polyethylene sheet moves to the gap of the arc block, the polyethylene sheet is directly cut by the cutting component. Then, the segmented polyethylene sheet is conveyed by the conveying component. The operator only needs to adjust the blade position once. Afterwards, the long strip of polyethylene sheet can be manually inserted into the feed hopper to cut the polyethylene sheet into segments according to the specifications, saving labor and allowing for rapid conveying of the segmented polyethylene sheet.

[0028] 2. In this invention, by setting up a chip collection structure, when the polyethylene board is cut into sections using the cutting component in the adjustment structure, the waste chips generated by the cutting will fall directly onto the chute and finally slide down the chute into the collection box, thereby quickly collecting the waste chips and keeping the working environment clean.

[0029] 3. In this invention, by setting an auxiliary structure, the tension of the conveyor belt can be quickly adjusted, improving the conveyor belt's conveying stability. At the same time, a brush can be used to clean the surface of the conveyor belt. Attached Figure Description

[0042] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, such as Figure 1-11 As shown, the present invention provides a segmented cutting device for processing polyethylene sheets, including a pad plate 1, a support frame 2 mounted on the upper surface of the pad plate 1, a drive wheel 3 and a driven wheel 4 respectively mounted on the upper end of the support frame 2, a conveyor belt 5 connected to the arc surfaces of the drive wheel 3 and the driven wheel 4, a fixing plate 6 welded to the upper surface of the pad plate 1, a motor B10 fixedly connected to one side of the fixing plate 6, the output end of the motor B10 fixedly connected to the drive wheel 3, the fixing plate 6 is provided with an adjustment structure 7 and a positioning frame 748, the lower end of the positioning frame 748 is provided with a chip collection structure 8, and the upper surface of the pad plate 1 is provided with an auxiliary structure 9.

[0045] The specific settings and functions of its adjustment structure 7, chip collection structure 8, and auxiliary structure 9 will be discussed below.

[0046] like Figure 3 , Figure 4and Figure 7 As shown, the adjusting structure 7 includes a fixed shaft 71 and a conveying assembly 72. The fixed shaft 71 is fixedly connected to the fixed plate 6. The conveying assembly 72 includes a collar 721, which is rotatably connected to the arc surface of the fixed shaft 71. Four arc blocks 722 are fixedly connected to one side of the collar 721. A reserved groove 723 is provided at one end of the fixed shaft 71. The size of the reserved groove 723 is adapted to the gap size of the four arc blocks 722. A toothed ring 724 is fixedly connected to one side of the collar 721. A motor 725 is fixedly connected to one side of the fixed plate 6. The motor 725... A gear 726 is fixedly connected to the output end. The gear 726 meshes with the gear ring 724. The polyethylene sheet is placed directly in the gap between the four arc blocks 722. After the polyethylene sheet is cut, the gear 726 can be driven to rotate by the motor 725, which in turn drives the gear ring 724 and the collar 721 to rotate. The arc blocks 722 drive the polyethylene sheet to rotate. When the polyethylene sheet is connected to the reserved groove 723 of the fixed shaft 71, the cut polyethylene sheet can slide directly onto the conveyor belt 5. The conveyor belt 5 is used to transfer the cut polyethylene sheet.

[0047] Two connecting plates 727 are fixed to the arc surface of the fixed shaft 71. The two connecting plates 727 are respectively fixed to the discharge hopper 728 and the feed hopper 729. The included angle formed by the discharge hopper 728 and the feed hopper 729 is 90°. A receiving groove is opened on the inner side of the feed hopper 729. Several round rollers 73 are evenly rotatably connected to the inner side of the receiving groove of the feed hopper 729, which can appropriately extend the feeding and discharging length, thereby improving the support strength of the polyethylene board.

[0048] A cutting assembly 74 for cutting polyethylene sheets is provided on one side of the feed hopper 729. The cutting assembly 74 includes an ear plate 741, which is installed on one side of the feed hopper 729. A slip ring 742 is slidably sleeved on the surface of the ear plate 741. A fixing frame 743 is welded to one side of the slip ring 742. An electric push rod 745 is fixedly connected to one end of the fixing frame 743. A motor A746 is fixedly connected to the output end of the electric push rod 745. A blade 747 is fixedly connected to the output end of the motor A746. A servo electric cylinder 744 is fixedly connected to one side of the connecting plate 727. The output end of the servo electric cylinder 744 is fixedly connected to the fixing frame 743, so that the position of the blade 747 can be adjusted by means of the servo electric cylinder 744. After adjustment, the blade 747 can be moved directly by means of the electric push rod 745 to cut the polyethylene sheet in sections. A positioning frame 748 is welded to one side of the feed hopper 729. A conveying hopper 749 is fixed to one end of the positioning frame 748. The end of the conveying hopper 749 away from the feed hopper 729 is a flared end, which allows polyethylene sheets to be directly placed into the flared end of the conveying hopper 749, providing a convenient way for operators to convey polyethylene sheets.

[0049] A limiting component 75 for limiting polyethylene sheets is provided on one side of the conveying hopper 749. The limiting component 75 includes a connecting frame 751, which is installed on one side of the conveying hopper 749 by bolts. A cylinder 752 is fixedly connected inside the connecting frame 751. A slot 754 is opened on the side of the conveying hopper 749 near the connecting frame 751. A pulley 753 is fixedly connected to the output end of the cylinder 752. This achieves the effect of limiting the polyethylene sheets during the conveying and cutting processes by using the cylinder 752 to drive the pulley 753 to squeeze the polyethylene sheets after they are put into the conveying hopper 749.

[0050] The surface of the slip ring 742 is provided with a measuring component 76 for predicting the cutting length of the polyethylene sheet. The measuring component 76 includes a rectangular hole 761, which is opened on the slip ring 742. A pointer 762 is fixed to the inner side of the rectangular hole 761. A scale groove 763 is provided on one side of the ear plate 741. This allows the operator to easily observe the distance of the blade 747 when the servo cylinder 744 is activated to move the blade 747, thereby better controlling the cutting length of the polyethylene sheet.

[0051] The overall effect of the adjustment structure 7 is as follows: by setting the adjustment structure 7, the position of the motor A746 and the blade 747 can be adjusted with the help of the metering component 76, thereby adjusting the segmented cutting length of the polyethylene board. Then, the motor B10 is started, and the motor B10 drives the conveyor belt 5. After the polyethylene board is put into the feed hopper 729, the moving polyethylene board can be limited with the help of the limiting component 75 without affecting the normal conveying of the polyethylene board. After the polyethylene board moves to the gap position of the arc block 722, the polyethylene board is directly cut with the help of the cutting component 74. Then, the segmented polyethylene board is conveyed with the help of the conveying component 72. The operator only needs to adjust the position of the blade 747 once. After that, the long strip of polyethylene board can be manually inserted into the feed hopper 729 to cut the polyethylene board into segments according to the specifications, saving labor and allowing for rapid conveying of the segmented polyethylene board.

[0052] like Figure 9 and Figure 10As shown, the chip collection structure 8 includes a connecting block 81, which is welded to the positioning frame 748. A connecting rod 82 is fixed to the lower end of the connecting block 81, and a hopper 83 is welded to the lower end of the connecting rod 82. A collection box 84 is slidably inserted into one end of the hopper 83. A buckle plate 86 is fixed to the lower surface of the hopper 83, and a locking block 87, which is a rubber block, is fixed to the short arm end of the buckle plate 86. A retaining ring 88 is slidably fitted onto the surface of the buckle plate 86, and the upper end of the retaining ring 88 is fixed to the collection box 84. After the polyethylene sheet is cut using the cutting component 74, the waste chips generated from the cutting can be collected into the collection box 84. The operator only needs to periodically move the collection box 84 to transfer the waste chips. A filter plate 85 is slidably inserted into the collection box 84. Two elastic ropes 89 are fixed to one end of the filter plate 85, and the other end of the elastic ropes 89 is fixed to the collection box 84, achieving the effect of separating and collecting waste chips and scraps.

[0053] The overall effect of the chip collection structure 8 is that, by setting up the chip collection structure 8, when the polyethylene sheet is cut in sections using the cutting component 74 in the adjustment structure 7, the waste chips generated by the cutting will fall directly onto the hopper 83 and finally slide down along the hopper 83 into the collection box 84, so as to quickly collect the waste chips and keep the working environment clean.

[0054] Example 2, based on Example 1, such as Figure 1 and Figure 11 As shown, the upper surface of the pad 1 is provided with an auxiliary structure 9, which includes a mounting plate 91. The mounting plate 91 is fixed to the pad 1 by bolts. A screw 92 is rotatably connected to the upper end of the mounting plate 91. An adjusting block 93 is threadedly connected to the arc surface of the screw 92. An adjusting frame 94 is fixed to one side of the adjusting block 93. A limit wheel 95 and a brush 96 are fixed to the upper and lower sides of the inner side of the adjusting frame 94, respectively. The arc surface of the limit wheel 95 is connected to the conveyor belt 5, which allows for quick adjustment of the position of the limit wheel 95 to adjust the tension of the conveyor belt 5. At the same time, the brush 96 can be used to clean the small amount of debris and waste adhering to the surface of the conveyor belt 5. A guide rod 97 is fixed to the upper surface of the mounting plate 91. The upper end of the guide rod 97 slides through the adjusting block 93, which can limit the rotation position of the adjusting block 93.

[0055] The overall effect of the auxiliary structure 9 is that by setting the auxiliary structure 9, the tension of the conveyor belt 5 can be quickly adjusted, the conveying stability of the conveyor belt 5 can be improved, and the surface of the conveyor belt 5 can be simply cleaned with the help of the brush 96.

[0056] The overall working principle is as follows: Before using the equipment to cut polyethylene sheets into sections for the first time, directly rotate the screw 92. The screw 92, through its thread, drives the adjusting block 93 to slide along the arc surface of the guide rod 97. The adjusting block 93 drives the adjusting frame 94 to move, causing the adjusting frame 94 to drive the limiting wheel 95 to press against the inner side of the conveyor belt 5 and move together with the conveyor belt 5, thereby adjusting the tension of the conveyor belt 5. While the conveyor belt 5 is moving, the brush 96 slides along the surface of the conveyor belt 5 to perform simple cleaning. Next, the retaining ring 88 of the collection box 84 is put onto the rubber retaining block 87, and then the collection box 84 is pushed so that the retaining ring 88 is locked onto the buckle plate 86.

[0057] After adjusting the conveyor belt 5, start the servo cylinder 744 to move the fixed frame 743. The fixed frame 743 drives the motor B10 to move the blade 747. At this time, you can observe the pointer 762 to obtain the cutting length information. After adjusting the blade 747 to the appropriate position, turn off the servo cylinder 744. At this time, the segmented cutting length of the polyethylene board is adjusted.

[0058] Next, the polyethylene sheet is directly placed into the feed hopper 729, and pushed so that it passes through the feed hopper 729 and is wedged into the gap between two adjacent arc blocks 722. Then, the cylinder 752 is activated, causing the pulley 753 to press against the polyethylene sheet, achieving the effect of limiting the polyethylene sheet without affecting its normal sliding. The roller 73 can change sliding friction to rolling friction, which reduces the friction between the polyethylene sheet and the feed hopper 729. Then, the electric actuator 745 and the motor A746 are activated. The motor A746 drives the blade 747 to rotate, and the electric actuator 745 drives the rotating blade 747 to press against the polyethylene sheet. The polyethylene sheet is cut, and the waste generated during the cutting process falls directly onto the hopper 83 and eventually into the collection box 84. The filter plate 85 can separate the waste and scrap, making it easier for operators to classify the waste later. After the cutting is completed, the motor 725 is started, which drives the gear 726 to rotate. The gear 726 drives the toothed ring 724 of the collar 721 to rotate with the help of the saw teeth. At this time, the arc block 722 rotates. When the cut polyethylene sheet rotates to the position of the reserved groove 723 of the fixed shaft 71, the polyethylene sheet will slide directly along the reserved groove 723 and slide from the position of the discharge hopper 728 onto the conveyor belt 5. The conveyor belt 5 directly transfers the cut polyethylene sheet.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
