Description

Technical Field

[0001] This utility model relates to the technical field of coated paper slitting device, and in particular to a coated paper sizing disc slitting device. Background Technology

[0002] The coated paper sizing and slitting device is a high-precision automated processing equipment designed specifically for coated paper materials. Its core function is to accurately slit coated paper rolls into circular sheets of a specific diameter. Coated paper, as a composite material with polyethylene (PE) and other polymer films coated on the paper surface through a special process, combines the flexibility of paper with the waterproof, oil-proof, and high-temperature resistant properties of film. It is widely used in food packaging, pharmaceuticals, electronic component protection, and industrial sealing.

[0003] When a coated paper slitting device is in use, in the scenario of batch slitting of coated paper, traditional disc slitting devices usually use two side clamps to linearly clamp and fix the coated paper. During the slitting process, the stability of the material is controlled only by the holding force in a single direction. During the slitting process, the edge of the coated paper is prone to curling, displacement or local damage due to uneven force. Especially in high-speed continuous operation scenarios, due to the limited clamping area and lack of vertical constraint, the slitting accuracy is difficult to guarantee. The disc edge burr rate is high and the size consistency is poor, resulting in a lower finished product qualification rate. This technical defect is particularly prominent in automated production lines that require high-precision disc slitting. Because the traditional clamping method cannot form a three-dimensional fixation of the coated paper in all directions, the dynamic stress during the slitting process is easily transmitted through the material body, causing unexpected tearing or deformation in non-slitting areas.

[0004] Therefore, to address the issue of inconvenience in improving the slitting quality of coated paper in batch processing scenarios, a sizing and slitting device for coated paper can be designed. When this device is in operation, the coated paper is first securely clamped from all directions by the cooperation of the cylindrical clamp and two sets of semi-circular clamps. Then, the slitting blade precisely slits the coated paper into round pieces. Finally, the slitting frame presses the slits down to the bottom of the inner cavity of the two sets of semi-circular clamps. Compared to traditional devices that only securely clamp the two sides of the coated paper, resulting in a high breakage rate during the slitting process, this device can significantly improve the slitting quality of the round pieces. Utility Model Content

[0005] To overcome the problem that traditional disc slitting devices typically use two side clamps to linearly hold and fix the coated paper, the slitting accuracy is difficult to guarantee due to the limited clamping area and lack of vertical constraint. This results in a high burr rate on the disc edges and poor dimensional consistency, making it inconvenient to improve the disc slitting quality when used in batch processing scenarios.

[0006] The technical solution of this utility model is as follows: a sizing and slitting device for coated paper discs, including a frame, a bracket fixedly connected to the top of the frame, two sets of retractable semi-circular clamps symmetrically arranged on the top of the frame, a lifting cylindrical clamp above the two sets of semi-circular clamps, the two sets of semi-circular clamps being of the same size as the cylindrical clamp when combined, and a rotating rod rotatably connected inside the cylindrical clamp, a slitting blade fixedly connected to one end of the rotating rod, and a lifting lower pressure frame inside the cylindrical clamp, the lower pressure frame being C-shaped.

[0007] Preferably, when the coated paper sizing and slitting device is working, it first drives the two semi-circular clamps to slide towards the center until the inner walls of the two sets of semi-circular clamps are in contact, forming a complete cylindrical structure. At this time, the bottom surface of the coated paper contacts the top of the two sets of semi-circular clamps. Then, it drives the cylindrical clamp to descend until the bottom of the cylindrical clamp is in contact with the top of the two sets of semi-circular clamps. At this time, the coated paper is fixedly clamped by the cylindrical clamp and the two sets of semi-circular clamps. At the same time, the cylindrical clamp drives the slitting knife to descend synchronously and pierce the inside of the coated paper. Then, it drives the rotating rod to drive the slitting knife to achieve circumferential rotation, performing the circular slitting operation on the coated paper. When the rotating rod is in the C position inside the cylindrical clamp, it can move up and down. When the lower pressure frame opens, it is driven to descend, pressing the slit discs down to the bottom of the two sets of semi-circular clamps. According to the program settings, when the intact part of the coated paper is above the semi-circular clamps, the discs are slit again following the above steps. The slit discs are temporarily stored in the two sets of semi-circular clamps. After all the slit operations are completed, one side of the semi-circular clamps is driven to separate, and the discs can be collected. In summary, this coated paper sizing disc slit slit device is ingeniously designed. The entire device realizes the integrated operation of batch disc slit ...

[0014] The beneficial effects of this utility model are:

[0015] 1. When the coated paper sizing and slitting device is working, it first drives the two semi-circular clamps to slide towards the center until the inner walls of the two sets of semi-circular clamps are in contact, forming a complete cylindrical structure. At this time, the bottom surface of the coated paper contacts the top of the two sets of semi-circular clamps. Then, it drives the cylindrical clamp to descend until the bottom of the cylindrical clamp is in contact with the top of the two sets of semi-circular clamps. At this time, the coated paper is fixedly clamped by the cylindrical clamp and the two sets of semi-circular clamps. At the same time, the cylindrical clamp drives the slitting knife to descend synchronously and pierce the inside of the coated paper. Then, it drives the rotating rod to drive the slitting knife to achieve circumferential rotation, performing the circular slitting operation on the coated paper. When the rotating rod is in the C position inside the cylindrical clamp, it can move up and down. When the lower pressure frame opens, it is driven to descend, pressing the slit discs down to the bottom of the two sets of semi-circular clamps. According to the program settings, when the intact part of the coated paper is above the semi-circular clamps, the discs are slit again following the above steps. The slit discs are temporarily stored in the two sets of semi-circular clamps. After all the slit operations are completed, one side of the semi-circular clamps is driven to separate, and the discs can be collected. In summary, this coated paper sizing disc slit slit device is ingeniously designed. First, the coated paper is stably clamped from all directions by the cooperation of the cylindrical clamps and the two sets of semi-circular clamps. Then, the slit knife is used to accurately slit the coated paper into discs. Finally, the lower pressure frame presses the slit discs down to the bottom of the two sets of semi-circular clamps. Compared with the traditional device that only stably clamps the two sides of the coated paper, resulting in a high breakage rate of the coated paper during disc slit ...

Secondly, during the slitting process, the drive motor drives the slitting blade to rotate circumferentially, which can efficiently complete the slitting of the discs. Thirdly, the setting of the lower pressure frame can promptly press down and collect the slitting discs, avoiding the accumulation of discs and affecting subsequent operations.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 and Figure 3 This utility model provides an embodiment of a sizing and slitting device for coated paper discs, including a frame 1, a bracket 2 fixedly connected to the top of the frame 1, two sets of retractable semi-circular clamps 3 symmetrically arranged on the top of the frame 1, a cylindrical clamp 4 that can be lifted and lowered above the two sets of semi-circular clamps 3, the two sets of semi-circular clamps 3 being of the same size as the cylindrical clamp 4 when combined, and also including a rotating rod 5, the rotating rod 5 being rotatably connected inside the cylindrical clamp 4, a slitting blade 6 being fixedly connected to the bottom of one end of the rotating rod 5, and a lifting and lowering pressure frame 7 being C-shaped inside the cylindrical clamp 4.

[0025] Please see Figure 2 and Figure 3Side plates 8 are symmetrically fixedly connected to the top of the frame 1 on both sides. Each set of side plates 8 is internally fixedly connected to an electrically controlled telescopic rod 9. The telescopic ends of the electrically controlled telescopic rod 9 are fixedly connected to the outer wall of the semi-circular clamp 3. Guide rods 10 are symmetrically fixedly connected between the two sets of side plates 8. Guide blocks 11 are symmetrically fixedly connected to both sides of the semi-circular clamp 3. The guide blocks 11 are slidably sleeved on the side walls of the guide rods 10. When the electrically controlled telescopic rods 9 on both sides are activated, their telescopic ends push the semi-circular clamps 3 on both sides towards the center. Because the guide blocks 11 are fixedly connected to both sides of the semi-circular clamp 3 and are slidably sleeved on the side walls of the guide rods 10, the guide blocks 11 slide towards the center. The guide rod 10 is fixedly connected to the side wall of the side plate 8, so the semi-circular clamp 3 can slide smoothly along the guide rod 10 until the inner walls of the two sets of semi-circular clamps 3 are in contact, forming a complete cylindrical structure. The top of the bracket 2 is fixedly connected to the hydraulic lifting rod 12, and the telescopic end of the hydraulic lifting rod 12 is fixedly connected to the fixed shell 13. The fixed shell 13 is fixedly connected to the top of the cylindrical clamp 4. When the hydraulic lifting rod 12 is started, the telescopic end of the hydraulic lifting rod 12 drives the cylindrical clamp 4 to descend through the fixed shell 13 until the bottom of the cylindrical clamp 4 is in contact with the top of the two sets of semi-circular clamps 3.

[0026] Please see Figure 3 and Figure 4 The cylindrical clamp 4 is rotatably connected to a rotating shaft 14. The lower end of the rotating shaft 14 is fixedly connected to the other end of the rotating rod 5. The inner wall of the cylindrical clamp 4 is fixedly connected to an annular slide rail 15. One end of the rotating rod 5 is slidably sleeved on the side wall of the annular slide rail 15. The rotating shaft 14 can drive the rotating rod 5 to achieve circumferential rotation along the annular slide rail 15. The top side of the cylindrical clamp 4 is fixedly connected to a drive motor 16. The output end of the drive motor 16 is provided with a drive shaft 17. The end of the drive shaft 17 is fixedly connected to a drive gear 18. The upper side wall of the rotating shaft 14 is fixedly connected to a rotating gear 19. The drive gear 18 meshes with the rotating gear 19. When the drive motor 16 is started, it can drive the drive gear 18 to rotate through the drive shaft 17. The drive gear 18 can drive the rotating shaft 14 to rotate through the rotating gear 19.

[0027] Please see Figure 3 and Figure 5 An electric lifting rod 20 is fixedly connected to the other side of the top of the cylindrical clamp 4. The telescopic end of the electric lifting rod 20 is fixedly connected to the lower pressing frame 7. The rotating shaft 14 is installed inside the lower pressing frame 7. When the rotating rod 5 is at the opening of the C-shaped lower pressing frame 7 inside the cylindrical clamp 4, the electric lifting rod 20 is activated. The telescopic end of the electric lifting rod 20 drives the lower pressing frame 7 to descend. The lower pressing frame 7 presses the cut circular pieces down to the bottom of the inner cavity of the two sets of semi-circular clamps 3. An unwinding mechanism 21 is set on one side of the top of the frame 1, and a winding mechanism 22 is set on the other side of the top of the frame 1. A controller 23 is fixedly connected to the side wall of the bracket 2. The coated paper is first wound and wound through the unwinding mechanism 21, and one end of it is wound and set on the side wall of the winding mechanism 22.

[0028] When the coated paper sizing and slitting device is working, the coated paper is first wound and wound by the unwinding mechanism 21, and one end of it is wound and set on the side wall of the winding mechanism 22. When the slitting operation begins, the two electrically controlled telescopic rods 9 are activated. The telescopic ends of the two electrically controlled telescopic rods 9 push the two semi-circular clamps 3 to slide towards the center. Since the guide blocks 11 are fixedly connected to both sides of the semi-circular clamps 3, and the guide blocks 11 are slidably sleeved on the side wall of the guide rod 10 fixedly connected between the side plates 8, the semi-circular clamps 3 can slide smoothly along the guide rod 10 until the inner walls of the two sets of semi-circular clamps 3 are in contact, forming a complete cylindrical structure. At this time, the bottom surface of the coated paper contacts the top of the two sets of semi-circular clamps 3.

[0029] Next, the hydraulic lifting rod 12 fixedly connected to the top of the bracket 2 is activated. The telescopic end of the hydraulic lifting rod 12 drives the cylindrical clamp 4 to descend through the fixed shell 13 until the bottom of the cylindrical clamp 4 is in contact with the top of the two sets of semi-circular clamps 3. At this time, the coated paper is fixedly clamped by the cylindrical clamp 4 and the two sets of semi-circular clamps 3. At the same time, the cylindrical clamp 4 drives the rotating rod 5 connected inside to descend synchronously. The bottom of one end of the rotating rod 5 is fixedly connected to the slitting knife 6.

[0030] When the cylindrical clamp 4 and the semi-circular clamp 3 are in contact, the slitting blade 6 pierces the inside of the coated paper. Then, the drive motor 16, which is fixedly connected to one side of the top of the cylindrical clamp 4, is started. The output end of the drive motor 16 drives the drive gear 18 to rotate through the drive shaft 17. The drive gear 18 meshes with the rotating gear 19, which is fixedly connected to the upper side wall of the rotating shaft 14, thereby driving the rotating shaft 14 to rotate. The lower end of the rotating shaft 14 is fixedly connected to the other end of the rotating rod 5, and one end of the rotating rod 5 is slidably sleeved on the side wall of the annular slide rail 15, which is fixedly connected to the inner wall of the cylindrical clamp 4. Therefore, the rotating shaft 14 can drive the slitting blade 6 to achieve circumferential rotation through the rotating rod 5, and perform circular slitting operation on the coated paper.

[0031] When the rotating rod 5 is at the opening of the C-shaped lower pressure frame 7 that can be raised and lowered inside the cylindrical clamp 4, the electric lifting rod 20 fixedly connected to the other side of the top of the cylindrical clamp 4 is activated. The telescopic end of the electric lifting rod 20 drives the lower pressure frame 7 to descend, and the lower pressure frame 7 presses the cut circular pieces down to the bottom of the inner cavity of the two sets of semi-circular clamps 3.

[0032] After completing a set of circular sheet cutting operations, first activate the hydraulic lifting rod 12 to raise the cylindrical clamp 4, then activate the winding mechanism 22 to wind and rewind the coated paper. According to the program set by the controller 23 fixedly connected to the side wall of the bracket 2, the winding stops when the intact part of the coated paper is above the semi-circular clamp 3. Then, repeat the above steps to cut the circular sheets again. The cut circular sheets are temporarily stored in the inner cavity of the two sets of semi-circular clamps 3. After completing all the cutting operations, activate the electric telescopic rods 9 on both sides to separate one side of the semi-circular clamp 3, and the circular sheets can be collected.

[0033] Firstly, the opening and closing of the semi-circular clamp 3 is controlled by the electrically controlled telescopic rod 9, which, together with the hydraulic lifting rod 12, enables the lifting and lowering of the cylindrical clamp 4. This allows for precise clamping of the coated paper, providing stable conditions for the slitting operation. Secondly, during the slitting process, the drive motor 16 drives the slitting blade 6 to rotate circumferentially, efficiently completing the slitting of the discs. Thirdly, the lower pressure frame 7 can promptly press down and collect the slitting discs, preventing disc accumulation from affecting subsequent operations. In summary, the entire device achieves integrated operation of batch disc slitting and disc collection of coated paper, reducing manual intervention, greatly improving production efficiency, and lowering production costs. It has high practical value and application prospects in the field of coated paper processing.

[0034] In summary, this coated paper sizing and slitting device is ingeniously designed. First, the coated paper is securely clamped from all directions by the cooperation of the cylindrical clamp 4 and the two sets of semi-circular clamps 3. Then, the slitting blade 6 precisely slits the coated paper into round pieces. Finally, the pressing frame 7 presses the slit round pieces down to the bottom of the inner cavity of the two sets of semi-circular clamps 3. Compared with traditional devices that only securely clamp the two sides of the coated paper, resulting in a high breakage rate of the coated paper during the round piece slitting process, this device can significantly improve the slitting quality of the round pieces.

[0035] Through the above steps, when the coated paper sizing and slitting device is working, it first drives the two semi-circular clamps 3 to slide towards the center until the inner walls of the two sets of semi-circular clamps 3 are in contact, forming a complete cylindrical structure. At this time, the bottom surface of the coated paper contacts the top of the two sets of semi-circular clamps 3. Then, it drives the cylindrical clamp 4 to descend until the bottom of the cylindrical clamp 4 is in contact with the top of the two sets of semi-circular clamps 3. At this time, the coated paper is fixedly clamped by the cylindrical clamp 4 and the two sets of semi-circular clamps 3. At the same time, the cylindrical clamp 4 drives the slitting blade 6 to descend synchronously and pierce the inside of the coated paper. Then, it drives the rotating rod 5 to drive the slitting blade 6 to achieve circumferential rotation, performing the circular slitting operation on the coated paper. When the rotating rod 5 is in the C position inside the cylindrical clamp 4, it can move up and down. When the lower pressure frame 7 opens, it is driven to descend, pressing the slit discs down to the bottom of the inner cavity of the two sets of semi-circular clamps 3. According to the program settings, when the intact part of the coated paper is above the semi-circular clamps 3, the discs are slit again according to the above steps. The slit discs are temporarily stored in the inner cavity of the two sets of semi-circular clamps 3. After all the slit operations are completed, one side of the semi-circular clamps 3 is driven to separate, and the discs can be collected. In summary, this coated paper sizing disc slit... The cutting device is ingeniously designed. First, the cylindrical clamp 4 and two sets of semi-circular clamps 3 work together to firmly clamp the coated paper from all directions. Then, the slitting blade 6 precisely cuts the coated paper into circular pieces. Finally, the pressing frame 7 presses the cut circular pieces down to the bottom of the inner cavity of the two sets of semi-circular clamps 3. Compared with the traditional device that only firmly clamps the two sides of the coated paper, resulting in a high breakage rate of the coated paper during the circular piece cutting process, this device can significantly improve the cutting quality of the circular pieces.
