Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a quick-release structure for a composite tape slitting cutter of a slitting machine. Background Technology

[0002] Composite tape is a strip material made from rubber, plastic, paper, cloth, etc. as the base material, through processes such as coating with adhesive and covering with a release layer. It combines the characteristics of multiple base materials with adhesive function. Since composite tape is usually produced in large rolls, and different industries and application scenarios have different requirements for its size specifications, it is necessary to use a slitting machine to accurately cut it into widths and lengths that meet specific needs, so as to meet diverse actual use requirements, improve production efficiency and product adaptability. A slitting machine is a special mechanical equipment that cuts wide materials longitudinally or transversely according to predetermined size specifications to obtain narrow materials of the required width.

A motor is fixedly connected to one side of the base, and a control switch is fixedly connected to the surface of the base. A chip collection groove is formed on the top surface of the base. A rotating shaft is rotatably connected to the other side of the base, and a cutting assembly is provided on the top of the rotating shaft. The cutting assembly includes a crossbar, which is fixedly connected to the other side surface of the base and is located on the top of the rotating shaft. A fixing plate is fixedly connected to the other side of the base and is located on the top of the crossbar. Multiple sliders are sleeved on the crossbar, and each slider has a dividing blade fixedly connected to its bottom. By designing the cutting assembly, it is convenient to slit large rolls of tape during tape processing, and it is also convenient to process large rolls of tape into smaller rolls of tape of different sizes during processing, thereby effectively improving the practicality and applicability of the device.

[0004] In the aforementioned prior art, since the cutting blade is fixed to the crossbar by a slider, and the top of the slider is connected to the fixing plate by a threaded head, nut, and fixing plate, this design ensures the stability of the cutting blade. However, when it is necessary to disassemble the blade, the nut must be loosened first and then the slider moved. This process is relatively cumbersome and not convenient for quick disassembly and assembly. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 7 This utility model provides a quick-release structure for a composite tape slitting cutter of a slitting machine, including a cutter holder 1. One end of the cutter holder 1 has a disassembly port 2, and a locking component 3 is provided at the disassembly port 2. The cutter holder 1 has an adjustment groove 4, and a sliding rod 5 is provided in the adjustment groove 4. Multiple sliders 6 are slidably arranged on the sliding rod 5. A sliding cutter body 7 is provided below the sliders 6. One side of the cutter holder 1 has a fixing groove 8, and a fixing plate 9 is slidably arranged in the fixing groove 8. Two screws 10 are provided on the fixing plate 9, and the fixing plate 9 abuts against the outer side of the multiple sliders 6. A fixing seat 11 is provided on one side of the cutter holder 1 via a connecting rod. Two threaded sleeves 13 are rotatably mounted via bearing 12, and the two threaded sleeves 13 are linked by a synchronous belt 14 and a synchronous pulley 15. One of the threaded sleeves 13 is provided with a driven gear 16, and the screw 10 is threaded into the corresponding threaded sleeve 13. The end face of the fixed base 11 is provided with a protective cover 17, and the threaded sleeve 13, the synchronous pulley 15, and the synchronous belt 14 are all located inside the protective cover 17. An installation cover 18 is provided on the outside of the protective cover 17, and the driven gear 16 extends into the installation cover 18. A driving gear is provided inside the installation cover 18 through a motor 19, and the driving gear meshes with the driven gear 16.

[0023] In this embodiment, the movement of the fixing plate 9 is controlled by a linkage system of the threaded sleeve 13 driven by the motor 19 on the tool holder 1, which realizes the quick assembly and disassembly of the slitting blade body 7. When the blade needs to be disassembled, the motor 19 is started, and the driving gear drives the driven gear 16 and the threaded sleeve 13 connected thereto to rotate. Under the linkage of the synchronous belt 14 and the synchronous pulley 15, the two threaded sleeves 13 rotate synchronously, causing the screw 10 to drive the fixing plate 9 to slide, releasing the resistance to the slider 6. There is no need to manually loosen the nuts one by one, which greatly simplifies the disassembly process and improves work efficiency. Similarly, during installation, the motor 19 can be reversed to make the fixing plate 9 return to its original position and resist the slider 6, completing the quick installation of the blade. The overall structure is easy to operate and effectively solves the problem of cumbersome disassembly and assembly of traditional blades, improving the flexibility and production efficiency of blade replacement in the slitting machine.

[0024] Furthermore, the disassembly port 2 is connected to the adjustment groove 4, and the slider 6 abuts against the two inner sides of the adjustment groove 4.

[0025] In this embodiment, this design enables the slider 6 to slide stably within the adjustment groove 4. The two inner sides of the adjustment groove 4 provide good guidance for the slider 6, ensuring that the slider 6 will not deviate during movement, thus ensuring the accuracy of the installation position of the slitting blade body 7 and thereby guaranteeing the quality of the slitting tape.

[0026] Furthermore, a scale 20 is provided above the tool holder 1, and each slider 6 is provided with an indicator arrow 21, and the indicator arrow 21 points to the value corresponding to the scale 20.

[0027] In this embodiment, the operator can quickly and accurately adjust the position of the slider 6 by observing the position of the indicator arrow 21 on the scale 20 according to the required cutting width, thereby precisely controlling the spacing between the cutting blade bodies 7 to meet the cutting requirements of composite tapes of different specifications.

[0028] Furthermore, two polygonal rods 22 are provided on the outer side of the protective cover 17, and the screw 10 has a polygonal groove 23, and the polygonal rods 22 are inserted into the polygonal groove 23.

[0029] In this embodiment, when the threaded sleeve 13 rotates to drive the screw 10 to move, the cooperation between the polygonal rod 22 and the polygonal groove 23 restricts the rotational freedom of the screw 10, ensuring that the screw 10 can only move in a straight line along the axial direction.

[0030] Furthermore, the locking assembly 3 includes two locking members and a locking seat 24. The locking members include a locking spring 25 and a locking rod 26. One end of the locking rod 26 is provided with a pull ring 27. The locking seat 24 has two locking grooves 28. One end of the tool holder 1 is provided with two locking blocks 29. The locking spring 25 is fixedly disposed on the outside of the pull ring 27 and the locking seat 24, and sleeved on the locking rod 26. The locking rod 26 is slidably connected to the locking seat 24 and is located on the outside of the locking seat 24. The two locking blocks 29 are respectively inserted into the locking seat 24 and are located in the corresponding locking grooves 28. The locking seat 24 is disposed at one end of the tool holder 1. The locking rod 26 is also inserted into the corresponding locking block 29 and passes through the locking block 29.

[0031] In this embodiment, when it is necessary to disassemble the slitting blade body 7, simply pull the pull ring 27 to disengage the locking rod 26 from the locking block 29, and the locking can be easily released. At this time, the slitting blade body 7 can be moved out through the adjustment groove 4 and the disassembly port 2. When the slitting blade body 7 is installed, the locking seat 24 is inserted into the locking block 29 at one end of the blade holder 1, so that the locking block 29 enters the locking groove 28. Then, the pull ring 27 is released. Under the action of the locking spring 25, the locking rod 26 automatically inserts into the locking block 29 and passes through it, thereby firmly connecting the locking seat 24 to the blade holder 1, preventing the slitting blade body 7 from coming out during use, ensuring the stability of the slitting blade body 7, and thus ensuring the slitting quality.

[0032] When using this utility model, first observe the scale 20 above the cutter holder 1 according to the required tape specifications. Adjust the sliding blade body 7 to a suitable spacing by sliding the slider 6 on the slide rod 5 and according to the scale 20 value indicated by the indicator arrow 21 on the slider 6. After adjustment, start the motor 19. The motor 19 drives the drive gear to rotate, which in turn drives the driven gear 16 and the threaded sleeve 13 to rotate. Under the linkage of the synchronous belt 14 and the synchronous pulley 15, the two threaded sleeves 13 rotate synchronously, causing the screw 10 to drive the fixing plate 9 to move towards the slider 6 and abut against multiple sliders 6, thus fixing the sliding blade body 7. When it is necessary to disassemble the blade, start the motor 19 again in reverse to rotate the blade body 7. The fixing plate 9 moves away from the slider 6, releasing the resistance. Then, the pull ring 27 at one end of the locking rod 26 in the locking assembly 3 is pulled to overcome the elastic force of the locking spring 25, causing the locking rod 26 to disengage from the locking block 29 at one end of the tool holder 1, thus releasing the connection between the locking seat 24 and the tool holder 1. Then, the slider 6 and the slitting blade body 7 are taken out together from the disassembly port 2, completing the quick disassembly. The whole process is simple and efficient. This method solves the technical problem that since the slitting blade is fixed to the crossbar by the slider, and the top of the slider is connected to the fixing plate by the threaded head, nut and fixing plate, although this design ensures the stability of the slitting blade, when it is necessary to disassemble the blade, the nut must be loosened first and then the slider moved. This process is relatively cumbersome and not convenient for quick disassembly and assembly.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
