Technical Field
[0001] This utility model belongs to the field of PET sheet production technology, and in particular relates to a cutting device for PET sheet production. Background Technology
[0002] PET sheets, or polyethylene terephthalate sheets, are a high-performance packaging material with excellent transparency and smoothness. They are excellent for display purposes, easy to emboss patterns and undergo metallization, giving products more aesthetic appeal and personalization. The production of PET sheets is a complex and meticulous process, in which cutting and processing PET sheets is a crucial step. By cutting PET sheets into different sizes and shapes, different fields and application scenarios can be met, satisfying diverse needs.
[0003] The problem with existing technology is that if no positioning measures are taken when cutting PET sheets, the PET sheets are prone to shifting or moving during the cutting process, resulting in uneven cut edges and inaccurate dimensions, which leads to a decrease in the cutting accuracy of PET sheets. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a cutting device for PET sheet production, which has the advantage of pressing and positioning the PET sheet to be processed to prevent deviation during the cutting process. It solves the problem that if the existing PET sheet is not positioned, it is easy for the PET sheet to shift or move during the cutting process, resulting in uneven cutting edges, inaccurate dimensions, and a decrease in the cutting accuracy of the PET sheet.
[0005] This utility model is implemented as follows: a cutting device for PET sheet production includes a base, a conveyor belt, a moving block, an opening groove, and a positioning structure. A fixed seat is fixedly connected to the bottom of the base, and the conveyor belt is mounted on the top of the base. A cutting table is fixedly connected to the right side of the top of the base, and a support arm is fixedly connected to the right side of the base. A moving cylinder is fixedly connected to the top of the support arm, and a cutting blade is fixedly connected to the output end of the moving cylinder. Fixed arms are slidably connected to the front and rear sides of the left side of the base. Moving grooves are formed on the sides of the two fixed arms that are close to each other, and several positioning grooves are equidistantly formed on the inner walls of the two moving grooves that are close to each other. The inner walls of the two movable slots are slidably connected to movable blocks, and the inner walls of the two movable blocks are respectively provided with open slots. Buffer seats are fixedly connected to the sides of the two movable blocks that are close to each other. Buffer springs are fixedly connected to the bottom of the inner walls of the two buffer seats. Buffer strips are fixedly connected to the bottom of the two buffer springs. The two ends of the buffer strips are slidably connected to the inner walls of the two buffer seats. Rotating rollers are rotatably connected to the bottom of the buffer strips via a rotating shaft. Movable openings are provided on the left and right sides of the two movable blocks. Sliding rods are fixedly connected to the left and right sides of the inner walls of the two open slots. Positioning structures are provided on the inner walls of the two open slots.
[0006] In a preferred embodiment of this utility model, the positioning structure includes a sliding bar, which is disposed on the top of the movable block. The bottom of the sliding bar extends and penetrates into the inner wall of the open groove. A movable component is fixedly connected to the top of the sliding bar, and a sliding rod is fixedly connected to the bottom of the sliding bar. By setting the sliding bar, when the movable component is pulled upward, it can drive the sliding bar to slide upward on the top of the movable block, thereby driving the sliding rod to move.
[0007] In a preferred embodiment of this invention, the sliding rod is disposed on the inner wall of the open groove, and the end of the sliding rod away from the buffer seat is fixedly connected to the bottom of the sliding strip. Two rotating arms are sleeved on the outer surface of the sliding rod. By setting the sliding rod, the sliding rod can be driven by the sliding strip to move upward on the inner wall of the open groove. The sliding rod that moves in this way can drive the two rotating arms to rotate respectively.
[0008] In a preferred embodiment of this invention, the two rotating arms are respectively positioned left and right on the inner wall of the open slot, and the two rotating arms are respectively positioned front and back on the inner wall of the open slot. Rotating slots are respectively formed on the surfaces of the two rotating arms at opposite ends. The inner walls of the two rotating slots are respectively in contact with the outer surface of the sliding rod. Linkage arms are respectively fixedly connected to the bottom of the two rotating arms. By setting the rotating arms, the sliding rod moves upward while pressing the inner walls of the two rotating slots, causing the two rotating arms to rotate relative to each other in a staggered manner. Thus, the two rotating arms rotate while simultaneously driving the two linkage arms to rotate.
[0009] In a preferred embodiment of this invention, the tops of the two linkage arms are respectively fixedly connected to the ends of the two rotating arms that are far apart from each other. The bottoms of the two linkage arms are respectively provided with openings, and the bottoms of the two linkage arms are respectively provided with displacement arms on the sides that are close to each other. By providing linkage arms, the two linkage arms can be staggered by the sliding rods through the openings during rotation, and push the two displacement arms respectively, so that the two linkage arms push the two displacement arms to move closer together.
[0010] In a preferred embodiment of this invention, the two displacement arms are slidably connected to the outer surface of the sliding rod at their midpoints. A positioning spring is fixedly connected to the side of the two displacement arms that is close to each other, and the positioning spring is sleeved on the outer surface of the sliding rod. A positioning block is fixedly connected to the side of the two displacement arms that is far apart from each other. By setting the displacement arms, the two displacement arms are pushed by the linkage arm and slide closer to each other on the surface of the sliding rod, compressing the positioning spring. The sliding of the two displacement arms then drives the two positioning blocks to move closer to each other.
[0011] In a preferred embodiment of this invention, the ends of the two positioning blocks that are far apart from each other extend out of the inner wall of the open slot through the moving port. The ends of the two positioning blocks that are far apart from each other are respectively inserted into the inner wall of the positioning slot. By setting the positioning blocks, when the two positioning blocks move closer together, they can be disengaged from the positioning slot and retracted into the open slot, thereby releasing the fixation of the moving block and allowing the moving block to slide up and down in the moving slot, thereby driving the buffer seat to adjust its height.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a base, conveyor belt, moving block, through slot and positioning structure, achieves the effect of solving the problem that if the existing PET sheet is not positioned during the cutting process, the PET sheet is prone to shifting or moving, resulting in uneven cutting edges and inaccurate dimensions, thus reducing the cutting accuracy of the PET sheet.
[0014] 2. This utility model, by setting a conveyor belt and moving blocks, enables the open slot and positioning structure to work together. The two moving blocks slide up and down in the moving slot to drive the buffer seat and buffer spring. The rotating roller compacts the PET sheet on the positioning conveyor belt, ensuring that the PET sheet remains in a fixed position during the cutting process and does not shift or move, thus ensuring the accuracy of PET sheet cutting.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 4As shown in the figure, a cutting device for PET sheet production provided by this utility model includes a base 1, a conveyor belt 2, a moving block 3, an opening groove 4, and a positioning structure 5. A fixed seat 101 is fixedly connected to the bottom of the base 1, and the conveyor belt 2 is provided on the top of the base 1. A cutting table 102 is fixedly connected to the right side of the top of the base 1, and a support arm 103 is fixedly connected to the right side of the base 1. A moving cylinder 104 is fixedly connected to the top of the support arm 103, and a cutting blade 105 is fixedly connected to the output end of the moving cylinder 104. Fixed arms 6 are slidably connected to the front and rear sides of the left side of the base 1, and moving grooves 601 are respectively opened on the side of the two fixed arms 6 that are close to each other. A plurality of fixed grooves are equidistantly opened on the inner wall of the two moving grooves 601 that are close to each other. The inner walls of the two movable slots 601 are slidably connected to the positioning slot 602, and the inner walls of the two movable slots 601 are respectively provided with open slots 4. The sides of the two movable slots 3 that are close to each other are respectively fixedly connected to the buffer seats 7. The bottom of the inner walls of the two buffer seats 7 are respectively fixedly connected to the buffer springs 701. The bottom of the two buffer springs 701 is fixedly connected to the buffer strips 702. The two ends of the buffer strips 702 are respectively slidably connected to the inner walls of the two buffer seats 7. The bottom of the buffer strips 702 is rotatably connected to the rotating rollers 703 through the rotating shaft. The left and right sides of the two movable slots 3 are respectively provided with moving openings 301. The left and right sides of the inner walls of the two open slots 4 are respectively fixedly connected to the sliding rods 401. The inner walls of the two open slots 4 are respectively provided with positioning structures 5.
[0023] refer to Figure 2 and Figure 4 The positioning structure 5 includes a sliding bar 8, which is located on the top of the movable block 3. The bottom of the sliding bar 8 extends through the inner wall of the open groove 4. A movable part 9 is fixedly connected to the top of the sliding bar 8, and a sliding rod 10 is fixedly connected to the bottom of the sliding bar 8.
[0024] The above solution is adopted: by setting a sliding bar 8, when the moving part 9 is pulled upward, it can drive the sliding bar 8 to slide upward on the top of the moving block 3, and the sliding bar 8 can drive the sliding rod 10 to move.
[0025] refer to Figure 4 The sliding rod 10 is set on the inner wall of the open slot 4. The end of the sliding rod 10 away from the buffer seat 7 is fixedly connected to the bottom of the sliding bar 8. Two rotating arms 11 are sleeved on the outer surface of the sliding rod 10.
[0026] The above solution is adopted: by setting a sliding rod 10, the sliding rod 10 can be driven by the sliding bar 8 to move upward on the inner wall of the open groove 4, and the sliding rod 10 can drive the two rotating arms 11 to rotate respectively.
[0027] refer to Figure 4Two rotating arms 11 are respectively positioned on the inner wall of the open slot 4, and two rotating arms 11 are respectively positioned on the inner wall of the open slot 4, with rotating slots 12 respectively opened on the surface of the two rotating arms 11 at opposite ends. The inner walls of the two rotating slots 12 are respectively in contact with the outer surface of the sliding rod 10, and linkage arms 13 are respectively fixedly connected to the bottom of the two rotating arms 11.
[0028] The above solution is adopted: by setting up a rotating arm 11, the sliding rod 10 presses the inner wall of the two rotating grooves 12 while moving upward, which drives the two rotating arms 11 to rotate in a staggered relative manner, so that the two rotating arms 11 drive the two linkage arms 13 to rotate at the same time.
[0029] refer to Figure 4 The tops of the two linkage arms 13 are fixedly connected to the ends of the two rotating arms 11 that are far apart from each other. The bottoms of the two linkage arms 13 are respectively provided with openings 14, and the bottoms of the two linkage arms 13 are respectively provided with displacement arms 15 on the sides that are close to each other.
[0030] The above scheme is adopted: by setting the linkage arm 13, the two linkage arms 13 can be offset from the sliding rod 401 through the opening 14 during the rotation, and push the two displacement arms 15 respectively. In this way, the two linkage arms 13 push the two displacement arms 15 to move closer together.
[0031] refer to Figure 4 The two displacement arms 15 are slidably connected to the outer surface of the sliding rod 401 in the middle. A positioning spring 16 is fixedly connected to the side of the two displacement arms 15 that is close to each other. The positioning spring 16 is sleeved on the outer surface of the sliding rod 401. A positioning block 17 is fixedly connected to the side of the two displacement arms 15 that is far away from each other.
[0032] The above scheme is adopted: by setting displacement arms 15, the two displacement arms 15 are pushed by the linkage arm 13 respectively, slide close to each other on the surface of the sliding rod 401, and compress the positioning spring 16. The two displacement arms 15 slide and then drive the two positioning blocks 17 to move closer to each other.
[0033] refer to Figure 3 and Figure 4 The ends of the two positioning blocks 17 that are far apart from each other extend out of the inner wall of the slot 4 through the moving port 301, and the ends of the two positioning blocks 17 that are far apart from each other are respectively inserted into the inner wall of the positioning slot 602.
[0034] The above solution is adopted: by setting positioning blocks 17, the two positioning blocks 17 can be disengaged from the positioning groove 602 and retracted into the open groove 4 when they move closer together, thereby releasing the fixation of the moving block 3, allowing the moving block 3 to slide up and down in the moving groove 601, thereby driving the buffer seat 7 to adjust its height.
[0035] The working principle of this utility model:
[0036] In use, the PET sheet to be processed is placed on the conveyor belt 2. Then, the moving part 9 is pulled upward, causing the sliding bar 8 to slide upward on the top of the moving block 3. At the same time, the sliding rod 10 moves upward in the open slot 4. As the sliding rod 10 moves, it presses against the inner walls of the two rotating slots 12, causing the two rotating arms 11 to rotate relative to each other in a staggered manner. While rotating, the two linkage arms 13 rotate synchronously. When the two linkage arms 13 rotate, they are offset from the sliding rod 401 through the opening 14, and push the two displacement arms 15 to slide closer on the sliding rod 401. The two displacement arms 15 slide and compress the positioning spring 16, causing the two positioning blocks 17 to disengage from the positioning slot 602 and return to the open slot 4, thereby releasing the fixation of the moving block 3. At the same time, another moving part is pulled. 9. Release the fixing of the other moving block 3. Then, the two moving blocks 3 slide down in the moving groove 601 at the same time, and simultaneously drive the two buffer seats 7 to move down, causing the buffer strip 702 and the rotating roller 703 to press down on the top of the PET sheet. At this time, the two buffer seats 7, through the two buffer springs 701, cooperate with the buffer strip 702 and the rotating roller 703 to press and position the PET sheet. Then, release the two moving parts 9, so that the positioning spring 16 pushes the two displacement arms 15 to slide, and drives the two positioning blocks 17 to be inserted into the positioning groove 602 respectively to fix the moving block 3. At the same time, the other moving block 3 is also fixed by the two positioning blocks 17. Then, the conveyor belt 2 moves the PET sheet to the cutting table 102, and drives the cutting knife 105 through the moving cylinder 104 to cut the PET sheet.
[0037] In summary, this PET sheet production cutting device, through the coordinated operation of the base 1, conveyor belt 2, moving block 3, through slot 4, and positioning structure 5, solves the problem that if PET sheets are not positioned during the cutting process, they are prone to shifting or moving, resulting in uneven cutting edges, inaccurate dimensions, and a decrease in the cutting precision of PET sheets.
