Description

Technical Field

[0001] This utility model relates to the field of release film technology, and in particular to a release film preparation and slitting device. Background Technology

[0002] Release film preparation and slitting equipment is a specialized mechanical device used to process release film. Its main function is to process large rolls of release film raw materials into finished products of the required width and specifications through unwinding, leveling, slitting, and rewinding processes. This equipment typically includes core components such as an unwinding device, a tension control system, a leveling mechanism, precision slitting blades, and a rewinding device. High-precision slitting of the release film is achieved through automated control. The slitting process can employ circular blades, flat blades, or lasers to ensure clean, burr-free edges while maintaining the integrity of the release surface. This equipment is widely used in industries such as adhesive tape, die-cutting, and electronic materials, and is a key production piece in the post-processing of release film. However, existing release film preparation and slitting equipment still suffers from problems such as the inability to adjust the blade position according to the thickness of the release film and the inability to perform separate collection of release film strips.

[0003] Therefore, it is essential to invent a release film preparation and slitting device. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a release film preparation and slitting device, which solves the problem that existing release film preparation and slitting devices still cannot adjust the blade position according to the thickness of the release film and cannot perform diversion and collection of release film strips. A release film preparation and slitting device includes a worktable, a sliding plate, a positioning plate, a support frame, a leveling roller, a slitting structure, and a guiding structure, wherein: the sliding plate is fixedly installed on the surface of the worktable, and the positioning plate is fixedly installed on both sides of the sliding plate surface; the support frame is fixedly installed on the outer side of the rear of the worktable; the leveling roller is installed on the inner side of the support frame; the slitting structure is fixedly installed on the outer side of the middle position of the worktable; and the guiding structure is fixedly installed on the front side of the worktable.

[0005] The slitting structure includes a sliding bracket, a sliding block, a rotating shaft, and a slitting blade. The sliding bracket is fixedly installed on the outer side of the middle position of the worktable, and the sliding block is slidably installed inside the sliding bracket. The rotating shaft is rotatably installed on the inner side of the sliding block, and the slitting blade is fixedly installed on the surface of the rotating shaft.

[0006] The guiding structure includes a support base, a horizontal conveyor plate, a limiting plate, and an upward guide roller. The support base is fixedly installed on the front side of the worktable, and the horizontal conveyor plate is fixedly installed on the surface of the support base. The limiting plate is fixedly installed on both sides of the surface of the horizontal conveyor plate, and the upward guide roller is rotatably installed on the inner side of the limiting plate.

[0007] The sliding support inside the sliding structure consists of two sets of rectangular steel metal frames, and the sliding block can reciprocate vertically inside the sliding support. The movement of the sliding block is driven by a screw transmission structure. The rotating shaft can drive the sliding blade to move along with the sliding block, and one end of the rotating shaft is connected to a drive motor, which drives the blade to rotate. The sliding blade consists of several parallel annular metal blades, which rotate along with the rotating shaft.

[0008] The horizontal conveyor plate inside the guide structure is made of a smooth steel plate, and it can carry the release film strips at odd positions to be conveyed horizontally outward. The upward guide roller is a rubber roller that cannot be rotated actively. The upward guide roller can convey the release film strips at even positions diagonally upward after contact. The guide structure conveys the release film strips at even and odd positions separately, and then winds them up separately.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This invention features a slitting structure that precisely slits the release film using a high-speed rotating slitting blade. The sliding block is vertically adjustable within a sliding support to accommodate release films of varying thicknesses, while the rotating shaft drives the slitting blade to ensure a clean, burr-free cut. The modular design allows for quick replacement of different sized annular slitting blades, making it suitable for various release film materials. Precision adjustment via a screw drive ensures slitting accuracy and stability. The slit film strips are then guided by a flow guide for efficient winding, resulting in a significantly improved overall design that enhances slitting efficiency and product quality.

[0010] The guide structure of this utility model enables the orderly diversion and precise guidance of the slit film strips. The smooth steel surface of the horizontal conveyor plate enables the horizontal conveying of single-number film strips, while the passive rubber roller design of the upward guide roller completes the oblique guidance of double-number film strips. The lateral limiting function of the limiting plate prevents deviation and ensures that each film strip is accurately conveyed along the preset path. This effectively solves the problem of winding up multiple film strips after simultaneous slitting, and significantly improves production efficiency and product yield. Attached Figure Description

[0018] The slitting structure 6 includes a sliding bracket 61, a sliding block 62, a rotating shaft 63, and a slitting blade 64. The sliding bracket 61 is fixedly installed on the outer side of the middle position of the workbench 1, and the sliding block 62 is slidably installed inside the sliding bracket 61. The rotating shaft 63 is rotatably installed on the inner side of the sliding block 62, and the slitting blade 64 is fixedly installed on the surface of the rotating shaft 63.

[0019] The guide structure 7 includes a support base 71, a horizontal conveyor plate 72, a limiting plate 73, and an upward guide roller 74. The support base 71 is fixedly installed on the front side of the workbench 1, and the horizontal conveyor plate 72 is fixedly installed on the surface of the support base 71. The limiting plate 73 is fixedly installed on both sides of the surface of the horizontal conveyor plate 72, and the upward guide roller 74 is rotatably installed on the inner side of the limiting plate 73.

[0020] The sliding support 61 inside the sliding structure 6 consists of two sets of rectangular steel metal frames, and the sliding block 62 can reciprocate vertically inside the sliding support 61. The movement of the sliding block 62 is driven by a screw transmission structure. The rotating shaft 63 can drive the sliding blade 64 to move along with the sliding block 62, and one end of the rotating shaft 63 is connected to a drive motor, which drives the blade to rotate.

[0022] This release film preparation and slitting equipment uses a base support on the worktable 1, along with a sliding plate 2 and a positioning plate 3, to achieve precise positioning of the film roll. The leveling roller 5 first flattens the release film, eliminating wrinkles, and then conveys it to the slitting structure 6. The slitting structure 6 uses an adjustable sliding block 62 to drive the slitting blade 64 to complete high-precision slitting, and the rotational cutting of the rotating shaft 63 ensures a smooth cut. The entire system adopts a modular design, realizing automated continuous operation from leveling to slitting.

[0023] After slitting, the film strips enter the guide structure 7 for intelligent diversion. The horizontal conveyor plate 72 handles the horizontal conveying of single-number film strips, while the upward guide rollers 74 provide oblique guidance for double-number film strips. The limiting plate 73 ensures the accuracy of the conveying path of each film strip. This bidirectional diversion design effectively solves the problem of multiple film strips entanglement, and works in conjunction with the subsequent winding device to complete the final material collection. Through the coordinated operation of various functional modules, the equipment significantly improves production efficiency while ensuring slitting accuracy, meeting the needs of industrial production.
