Description

Technical Field

[0001] This application relates to the field of cutting equipment, and more particularly to a cutting apparatus for producing release paper. Background Technology

[0002] Release paper, also known as silicone paper or anti-stick paper, is a special functional paper with a surface coated with an organosilicon release agent. The production process of release paper includes: imprinting the pattern, manufacturing the printing process; feeding the paper blank, extrusion lamination, cutting, and winding. After the extrusion lamination process, the edges of the release paper need to be trimmed using a cutting device to ensure their smoothness.

[0003] Existing cutting devices typically consist of a support, a positioning seat, a swing arm, a cutter, and a drive structure. The support is installed at both ends of the conveying mechanism used to transport the release paper. When cutting the release paper, bolts are used to fix the positioning seat to the support, and the drive structure drives the swing arm to rotate until the cutter at one end of the swing arm contacts the edge of the release paper on the outside of the conveying roller. As the release paper is continuously transported, the cutting of the edge of the release paper is completed.

[0004] In the existing technology, it is not convenient to adjust the position of the cutter or replace the cutter, especially when the cutting position needs to be changed frequently or the cutting width needs to be adjusted. This will not only affect the efficiency of the cutter position adjustment, but also affect the production cutting efficiency of the release paper, thus reducing the practicality of the cutting device. Utility Model Content

[0005] To facilitate the adjustment and replacement of the cutter and improve the cutting efficiency of release paper, this application provides a release paper production cutting device.

[0006] The release paper production and cutting device provided in this application adopts the following technical solution:

[0007] A release paper production and cutting device includes a conveyor frame for conveying release paper, supports installed at both ends of the conveyor frame, a swing arm installed on the upper side of the supports, and a cutter installed at one end of the swing arm. A locking member for locking the cutter is installed at one end of the swing arm. A driving member for driving the swing arm to rotate is installed on one side of the supports. A hinge is connected to the lower end of the swing arm. A positioning seat is fixedly connected to the lower side of the hinge. A limiting member for limiting the positioning seat is fixedly connected to the upper end of the supports. An adjusting member for adjusting the position of the positioning seat is installed on the upper side of the supports.

[0008] By adopting the above technical solution, the swing arm is connected to the positioning seat via a hinge, which ensures the stability and flexibility of the swing arm rotation. The positioning seat cooperates with the bracket through limiting and adjusting parts, which not only prevents the positioning seat from being misaligned during sliding, but also allows for quick adjustment of the position of the swing arm and the cutter. Furthermore, the locking part facilitates the user's replacement of the cutter, reducing the time and effort spent on replacing and adjusting the cutter position, thereby improving the cutting efficiency of release paper and enhancing the practicality of the device.

[0009] Optionally, the locking component includes a locking plate and a knob. One end of the swing arm has an opening groove for the locking plate to slide. The opening groove and the side adjacent to the locking plate have an installation groove for the cutter to be installed. The outer wall of the knob is threaded to the inner wall of the swing arm and one end is rotatably connected to one side of the locking plate.

[0010] By adopting the above technical solution, the cutter can be quickly fixed or loosened by tightening and loosening the knob, without the need for complicated tools or cumbersome operating procedures. This makes the installation and replacement of the cutter more convenient. Even when the cutter needs to be replaced frequently, the replacement can be completed quickly, reducing downtime and improving production efficiency.

[0011] Optionally, the limiting component includes two sliding rods and two limiting blocks. The two limiting blocks are respectively fixedly connected to the two ends of the two sliding rods, and the lower side of the limiting blocks is fixedly connected to the bracket. The lower end of the positioning seat is provided with a sliding groove that is slidably connected to the outer wall of the two sliding rods.

[0012] By adopting the above technical solution, the positioning seat can move within a certain range through the sliding connection between the slide groove and the slide rod. At the same time, the limiting block can prevent the positioning seat from disengaging from the slide rod, making the adjustment of the cutter position more precise and avoiding cutting deviations caused by the instability of the positioning seat, thereby improving the cutting quality of the release paper.

[0013] Optionally, the adjusting component includes a handwheel and a threaded rod. Bearings are fixedly connected to the outer walls of both ends of the threaded rod. The outer walls of the two bearings are respectively connected to the inner walls of the limiting block, and the outer wall of the threaded rod is threadedly connected to the inner wall of the positioning seat. The handwheel is fixedly connected to one end of the threaded rod.

[0014] By adopting the above technical solution, the threaded connection between the threaded rod and the positioning seat allows the rotation of the handwheel to be converted into the linear movement of the positioning seat, thereby achieving fine adjustment of the cutter position. This not only meets the needs of different cutting widths and improves the adaptability and flexibility of the cutting device, but also ensures the accuracy of the cutting position and avoids cutting quality problems caused by inaccurate position adjustment.

[0015] Optionally, the driving component includes a driving cylinder and two connecting blocks. One end of the piston rod of the driving cylinder is fixedly connected to one of the connecting blocks, and one side of the other connecting block is fixedly connected to one side of the swing arm. The adjacent ends of the two connecting blocks are hinged to each other. The other end of the driving cylinder is rotatably connected to a fixing rod, and one end of the fixing rod is fixedly connected to one side of the bracket.

[0016] By adopting the above technical solution, the piston rod of the drive cylinder is connected to the swing arm through a connecting block, enabling the swing arm to rotate quickly and stably, thereby driving the cutter to perform the cutting action. This not only ensures the reliability of the cutting action but also allows for adjustment of the stroke and speed of the drive cylinder as needed, achieving control over the cutting speed and force, further improving cutting efficiency and quality.

[0017] Optionally, the end of the swing arm opposite to the cutter is connected to a fastener that is threadedly connected to the hinge, and the hinge has multiple positioning holes for the fastener to be turned in.

[0018] By adopting the above technical solution, the connection between the hinge and the swing arm is made more secure and reliable. Through the cooperation of fasteners and positioning holes, the swing arm can be fixed in the appropriate position of the hinge, preventing the swing arm and the hinge from loosening or shifting during use, thereby ensuring the stability of the swing arm and the cutting accuracy of the cutter.

[0019] Optionally, the locking plate is fixedly connected to two limit rods on both ends of the side near the knob, and both limit rods pass through the inner wall of one end of the swing arm.

[0020] By adopting the above technical solution, the movement range of the locking plate can be limited, preventing the locking plate from shaking or shifting during the tightening or loosening of the knob. This ensures that the locking plate firmly locks the cutter, avoiding the loosening of the cutter due to the instability of the locking plate, thereby improving the stability of the cutting process.

[0021] Optionally, a limiting strip is fixedly connected to one side of the locking plate, and a limiting groove is provided at one end of the swing arm for the limiting strip to be inserted.

[0022] By adopting the above technical solution, the limiting strip is inserted into the limiting groove, which can ensure that the locking plate is accurately positioned in the swing arm, further improving the stability and reliability of the cutter installation, and preventing the cutter from tilting or misaligning due to force during use, thereby further improving the cutting quality and efficiency.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. This application allows for quick fixing and loosening of the cutter by tightening and loosening the knob. Furthermore, through the cooperation of the limiting and adjusting components, the positioning seat can move stably within a certain range, enabling rapid adjustment of the cutter position. This reduces downtime and improves the practicality and cutting efficiency of the device.

[0025] 2. The swing arm of this application is connected to the positioning seat via a hinge, which enables the drive component to achieve rapid and stable rotation of the swing arm, driving the cutter to perform reliable cutting action, ensuring the stability of the cutting process. Furthermore, the locking component can firmly lock the cutter, preventing the cutter from loosening or misaligning during the cutting process, further ensuring the stability of the cutting process and improving the cutting quality.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a release paper production and cutting device.

[0033] Reference Figure 1The cutting device includes a conveyor frame 1 and supports 2 installed at both ends of the conveyor frame 1. The conveyor frame 1 consists of a U-shaped frame and two guide rollers, which guide the release paper to pass stably through the conveyor frame 1. The supports 2 are L-shaped frames, and the two supports 2 are symmetrically arranged to ensure structural stability. Positioning seats 8 are installed at the upper ends of both supports 2. A hinge 7 is fixedly connected to the upper side of each positioning seat 8, and a swing arm 3 is fixedly installed on one side of each hinge 7. The hinge 7 ensures that the swing arm 3 can rotate flexibly on the upper side of the positioning seat 8. A cutter 4 for cutting the release paper is installed at one end of each swing arm 3. A fixing rod 11 is fixedly connected to the side wall of the support 2. A drive component 6 for pulling the swing arm 3 to rotate is rotatably connected to the outer wall of the fixing rod 11. The drive component 6 pulls the swing arm 3 to rotate until the cutter 4 contacts the release paper outside the guide roller, thus cutting the release paper.

[0034] When cutting the release paper, the cutter 4 is first installed at one end of the swing arm 3. Then, the swing arm 3 is controlled by the drive unit 6 to rotate along the hinge 7 until the cutter 4 contacts the outer side of the upper guide roller. As the release paper is conveyed between the guide rollers, the cutter 4 can continuously cut the edge of the release paper to facilitate subsequent processing of the release paper.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The upper end of the bracket 2 is fixedly connected to a limiting member 9 for restricting the movement range of the positioning seat 8. The limiting member 9 consists of two sliding rods 91 and two limiting blocks 92. The two limiting blocks 92 are fixed to both ends of the two sliding rods 91 and their lower ends are fixedly connected to the bracket 2. The lower end of the positioning seat 8 has a sliding groove 81 that connects to the outer wall of the sliding rod 91. The inner wall of the sliding groove 81 is slidably connected to both sides of the two sliding rods 91. The positioning seat 8 is located between the two limiting blocks 92. The two limiting blocks 92 can prevent the positioning seat 8 from detaching from the sliding rods 91 and the bracket 2 during the sliding process, and can also limit the sliding range of the positioning seat 8.

[0036] Reference Figure 1 , Figure 2 and Figure 3 Both blades of the hinge 7 have multiple positioning holes 71. One blade is fixedly connected to the upper side of the positioning seat 8, and the inner wall of the positioning hole 71 of the other blade is threaded with a fastener 32 that connects to the swing arm 3. The fastener 32 passes through the swing arm 3 and rotates into the positioning hole 71 to fix the swing arm 3 to the blade of the hinge 7, ensuring the stability of the connection between one end of the swing arm 3 and the hinge 7. The multiple positioning holes 71 allow the user to adjust the connection position between the swing arm 3 and the hinge 7 according to their needs, improving the practicality of the structure. In this application, the fastener 32 is a bolt; in other embodiments, the fastener 32 can also be a screw, rivet, or other types.

[0037] Reference Figure 1 Figure 2 and Figure 3 The adjusting component 10 includes a handwheel 101 and a threaded rod 102 fixedly connected to the handwheel 101. Both ends of the threaded rod 102 are fixedly connected to bearings 103, which are also fixedly connected to the inner walls of the limiting blocks 92. The bearings 103 ensure that the threaded rod 102 can rotate stably between the two limiting blocks 92 and prevent misalignment or slippage during rotation. The outer wall of the threaded rod 102 is threadedly connected to the inner wall of the positioning seat 8, and the rotation of the threaded rod 102 can move the positioning seat 8. By rotating the handwheel 101 to rotate the threaded rod 102, the positioning seat 8 can slide along the slide bar 91 on the upper side of the bracket 2, allowing for adjustment of the position of the positioning seat 8 and facilitating user operation.

[0038] Reference Figure 1 , Figure 3 The driving component 6 includes a driving cylinder 61 and a connecting block 62 fixedly connected to one end of the piston rod of the driving cylinder 61. One end of the connecting block 62 is hinged to another connecting block 62, and one end of the other connecting block 62 is fixedly connected to the side wall of the swing arm 3. When the driving cylinder 61 is activated, the swing arm 3 is pulled to adjust its angle through the hinged rotation between the two connecting blocks 62. The rotational connection between the end of the driving cylinder 61 and the fixed rod 11 prevents the swing arm 3 from jamming during rotation, thus ensuring the flexibility of the swing arm 3's rotation.

[0039] Reference Figure 2 , Figure 3 and Figure 4A locking element 5 for locking the cutter 4 is fixedly installed at one end of the swing arm 3. The locking element 5 includes a locking plate 51, a knob 52 rotatably connected to one side of the locking plate 51, and a limiting rod 53 fixedly connected to both ends of the locking plate 51. One end of the swing arm 3 has an opening groove 31 for the locking plate 51 to slide, and the outer wall of the knob 52 is threaded to the inner side of the swing arm 3. Rotating the knob 52 allows the locking plate 51 to slide on the inner wall of the opening groove 31. The limiting rod 53 passes through the swing arm 3 and slides inside the opening groove 31. When the locking plate 51 slides, the limiting rod 53 slides on the inner wall of the swing arm 3 to prevent the locking plate 51 from becoming misaligned during the sliding process. An installation groove 54 for inserting and installing the cutter 4 is provided between the locking plate 51 and the side wall of the opening groove 31. The installation groove 54 is used to position and install the cutter 4 to ensure the installation position of the cutter 4. A limiting strip 511 is fixedly connected to one side of the locking plate 51. A limiting groove 33 is provided on one side of the swing arm 3 for the insertion of the limiting strip 511. The limiting groove 33 is connected to one end of the mounting groove 54. The cooperation between the limiting groove 33 and the limiting strip 511 is used to further ensure the stability of the connection between the locking plate 51 and the swing arm 3, and to prevent the cutter 4 from being misaligned during use.

[0040] When installing the cutter 4, first turn the knob 52 to slide the locking plate 51 inside the opening groove 31, exposing the mounting groove 54. Then, move the cutter 4 between the locking plate 51 and the side wall of the opening groove 31. Next, turn the knob 52 in the opposite direction to slide the locking plate 51 inside the opening groove 31 until one side of the locking plate 51 pushes the cutter 4 against the inner wall of the mounting groove 54, thus fixing the cutter 4 in the mounting groove 54. Reversing the steps above will then complete the disassembly of the cutter 4.

[0041] The implementation principle of the release paper production and cutting device in this embodiment is as follows: When the device is running, the release paper after the extrusion and lamination process is conveyed to the next process through the guide roller of the conveyor frame 1. When the release paper passes through the guide roller: two drive cylinders 61 are activated to pull the two swing arms 3 to rotate until the cutter 4 at one end of the two swing arms 3 simultaneously contacts the two ends of the release paper. As the release paper is continuously conveyed, the cutter 4 continuously cuts the edges of the release paper to complete the cutting work of the release paper edges. When it is necessary to replace the cutter 4: start the drive cylinder 61 to push the swing arm 3 to rotate, so that the cutter 4 is disengaged from the release paper and guide roller; then, loosen the knob 52 to release the lock on the old cutter 4 and remove the old cutter 4; then, install the new cutter 4 in the mounting groove 54 between the locking plate 51 and the opening groove 31, and then tighten the knob 52 in the opposite direction to push the locking plate 51 to lock the new cutter 4. After the replacement of the cutter 4 is completed, start the drive cylinder 61 again to drive the swing arm 3 to rotate until the cutter 4 is in contact with the release paper and guide roller again to continue the cutting work. When the position of cutter 4 needs to be adjusted: start the drive cylinder 61 to push the swing arm 3 to rotate until the cutter 4 disengages from the release paper and guide roller; then, turn the handwheel 101 to drive the threaded rod 102 to rotate, so that the positioning seat 8 moves along the slide rod 91 between the two limit blocks 92, thereby driving the swing arm 3 to move and adjust the position of cutter 4; during the movement of the swing arm 3, the drive cylinder 61 will slide along the fixed rod 11, so that the drive cylinder 61 and the swing arm 3 are always in a horizontal state; finally, start the drive cylinder 61 again to drive the swing arm 3 to rotate until the cutter 4 re-contacts the release paper, completing the adjustment of the position of cutter 4.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
