Description

Technical Field

[0001] This utility model relates to the field of release paper production technology, specifically to a release paper production and trimming equipment. Background Technology

[0002] Release paper is a special type of paper coated with silicone oil or other anti-stick materials on the surface of ordinary paper; it is also known as silicone paper. It possesses isolating and anti-stick properties, allowing objects such as tapes, labels, and stickers adhered to its surface to be easily peeled off without leaving adhesive residue. Release paper can be classified by color (e.g., natural color, white), by weight, and by surface treatment (e.g., single-sided or double-sided). In the packaging industry, it is used in the production of tapes and self-adhesive labels; in the medical field, it serves as a backing paper for plasters and dressings; and in the electronics industry, it aids in the adhesion and protection of electronic components. Release paper plays an important role in multiple fields due to its unique properties, providing convenience for the processing, use, and storage of goods.

[0003] After initial production, the release paper is a large roll of base paper. During production, due to factors such as equipment fluctuations and material tension, defects such as serrated edges, wrinkles, or tears are prone to occur at the edges, and the width may also not match the specifications of subsequent slitting equipment. Therefore, pre-cutting is required. Currently, most scenarios rely on manual operation: workers first visually mark the cutting position and width on the base paper or use tools, then transfer the paper to the cutter and manually press down to cut. Although this method is flexible, it is greatly affected by human factors. Errors in marking and positioning, inconsistent pressure and angle can easily lead to insufficient width accuracy after cutting, or even cause new edge damage, affecting the efficiency of subsequent slitting and the uniformity of the finished product. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a release paper production edge-cutting device that uses mechanical clamping for better fixation and mechanical movement for cutting, resulting in smaller errors.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a release paper production and trimming device, comprising:

[0006] The support includes a base plate and a cutting frame, wherein the cutting frame is fixedly mounted on one side edge above the base plate by a support rod;

[0007] A fixed carrier plate is slidably mounted on a base plate and driven by an electric push rod fixed on the base plate. The fixed carrier plate is symmetrically provided with clamping bars, which are slidably mounted on the fixed carrier plate and driven to move closer and further apart by a double-headed screw driver fixed on the fixed carrier plate.

[0008] The cutting blade is located below the cutting frame and is driven by a lead screw driver that is fixed on the cutting frame.

[0009] Furthermore, the base plate is provided with support feet at the four corners below, and the support rods are symmetrically fixed at both ends below the cutting frame.

[0010] Furthermore, the fixed carrier plate is symmetrically provided with a sliding strip on both sides, the base plate is provided with a guide groove matching the sliding strip, a moving block is fixedly provided in the lower center of the fixed carrier plate, the lower end of the moving block slides through the base plate and is connected to the electric push rod, and the base plate is provided with a through groove matching the moving block.

[0011] Furthermore, the dual-headed lead screw driver is embedded in the fixed carrier plate, and the bottom surface of the clamping bar is attached to the fixed carrier plate.

[0012] Furthermore, a second slide bar is symmetrically provided below the clamping bar, and a groove matching the second slide bar is provided on the fixed carrier plate.

[0013] Furthermore, the lower end of the cutting blade is fitted to the side wall of the base plate.

[0014] Compared with existing technologies, the advantages of this invention are as follows: Symmetrically arranged clamping bars, driven by a double-headed screw driver, achieve stable fixation of the release paper. This mechanical clamping method, compared to traditional manual fixation, can apply pressure evenly, preventing displacement or wrinkling of the release paper during cutting, ensuring precise paper positioning, and laying a reliable foundation for subsequent cutting processes.

[0015] In the cutting process, the equipment uses a lead screw drive to move the cutting blade mechanically for cutting. Compared to manual operation or simple mechanical structures, the lead screw drive has higher transmission precision and stability, and can accurately control the movement trajectory and cutting force of the cutting blade. This significantly reduces errors during the cutting process, ensuring that the cut edges of the release paper are neat and smooth, accurately controlling the cutting size, reducing release paper waste caused by cutting errors, and significantly improving production efficiency and material utilization.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 2 Appendix Figure 3 A release paper production edge trimming device includes: a support, including a base plate 1 and an edge trimming frame 2. The edge trimming frame 2 is fixedly mounted on one side edge of the base plate 1 by support rods 3. Support feet 10 are provided at the four corners below the base plate 1. The support rods 3 are symmetrically fixed at both ends below the edge trimming frame 2, which can improve the stability of the device and prevent shaking during operation. At the same time, the support rods 3 are located close to both ends of the edge trimming frame 2, which also facilitates the movement and cutting of the edge trimming knife 8.

[0023] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 A fixed carrier plate 4 is slidably mounted on a base plate 1 and driven by an electric push rod 5 fixed on the base plate 1. A sliding strip is symmetrically arranged on both sides of the fixed carrier plate 4. A guide groove 11 matching the sliding strip is provided on the base plate 1. A moving block 12 is fixedly mounted in the lower center of the fixed carrier plate 4. The lower end of the moving block 12 slides through the base plate 1 and connects to the electric push rod 5. A through groove 13 matching the moving block 12 is provided on the base plate 1. The sliding strip and the guide groove 11 cooperate to restrict the movement direction of the fixed carrier plate 4. The moving block 12 and the through groove 13 ensure smooth sliding under the drive of the electric push rod 5, guaranteeing the accuracy of the release paper feeding.

[0024] Combined with appendix Figure 1 Appendix Figure 4 The fixed carrier plate 4 is symmetrically provided with clamping strips 6. The clamping strips 6 are slidably disposed on the fixed carrier plate 4 and are driven to move closer and further apart by a double-ended lead screw driver 7 fixed on the fixed carrier plate 4. The double-ended lead screw driver 7 is embedded in the fixed carrier plate 4, and the bottom surface of the clamping strips 6 is attached to the fixed carrier plate 4, which enables the clamping strips 6 to stably clamp the lower release paper, resulting in a good clamping and fixing effect. The clamping strips symmetrically provided below the clamping strips 6 are provided with sliding grooves 14 on the fixed carrier plate 4 to match the sliding strips 2, so that the clamping strips 6 slide more smoothly and at the same time prevent them from shifting during movement, ensuring the accurate clamping position of the release paper.

[0025] Combined with appendix Figure 2 Appendix Figure 3The cutting blade 8 is located below the cutting frame 2 and is driven by a screw driver 9 fixed on the cutting frame 2. The lower end of the cutting blade 8 is attached to the side wall of the base plate 1, which helps to improve the cutting accuracy and reduce the waste of release paper.

[0026] The specific implementation of this utility model is as follows: Connect the device to an external power source. Neatly stack the release paper onto the fixed carrier plate 4, aligning the position to be cut with the edge of the fixed carrier plate 4 near the cutting blade 8. An external pressing device can be used to hold the release paper in place. Activate the double-headed screw drive 7 on the fixed carrier plate 4, causing the clamping bars 6 to slide within the slide groove 14, thus clamping the release paper closer together. Next, activate the electric push rod 5 on the base plate 1. The electric push rod 5 pushes the moving block 12 to slide within the through groove 13, thereby moving the fixed carrier plate 4 along the guide groove 11 on the base plate 1, conveying the release paper to below the cutting frame 2, aligning the position of the release paper to be cut with the cutting blade 8. At this time, activate the screw drive 9 on the cutting frame 2. The screw drive 9 drives the cutting blade 8 to move, and the lower end of the cutting blade 8 cuts the release paper against the side wall of the base plate 1. Throughout the process, the support rod 3 fixes the cutting frame 2 above the base plate 1, and the support feet 10 support the device, ensuring its stability. The fixed carrier plate 4 cooperates with the guide groove 11 through the first slide bar, and the moving block 12 and the through groove 13 ensure smooth movement. The clamping bar 6 cooperates with the slide groove 14 through the second slide bar to ensure accurate clamping position, thereby achieving precise edge cutting of the release paper.
