Description
Technical Field
[0001] This utility model relates to the field of edge trimming structure technology, and in particular to a positioning edge trimming structure for school uniform production. Background Technology
[0002] School uniform fabric trimming equipment is a type of specialized machinery used in the school uniform manufacturing process to precisely process the edges of school uniform fabric. Structurally, it mainly consists of several key components, including a frame, cutting system, positioning system, power system, and control system. In large-scale school uniform production, ensuring the consistency of size and pattern for each uniform is crucial. Utilizing a precise positioning system, the school uniform fabric trimming equipment can precisely trim the fabric according to the designed dimensions. For example, for areas such as sleeves and trouser legs, the equipment can accurately control the length and width of the trimmed edges, resulting in minimal dimensional errors in the cut fabric. This ensures that the final produced school uniforms are of uniform specifications, meeting schools' requirements for neat and uniform student attire.
[0003] The positioning and cutting structures currently used in school uniform production have many obvious shortcomings. The most prominent problem is poor positioning accuracy. In existing structures, the positioning scales mostly use a traditional marking method, requiring workers to visually read the scales for fabric positioning. This is highly susceptible to positioning errors due to visual bias. Furthermore, the fixing effect of the positioning clips is not ideal. During cutting, the fabric is prone to slight displacement due to vibrations or external forces, affecting the final cutting accuracy. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to propose a positioning and cutting structure for school uniform production, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of this utility model provides a positioning and trimming structure for school uniform production, including a base. A processing table is fixedly mounted on the top surface of the base by bolts. A C-shaped ring cutter is fixedly connected to one side of the base. The processing table is located inside the C-shaped ring cutter. An L-shaped connecting plate is fixedly mounted on the frame of the C-shaped ring cutter by bolts. A cylinder is fixedly connected inside the L-shaped connecting plate. A lifting plate is fixedly connected to the output end of the cylinder. Two symmetrically arranged first springs are fixedly connected to the top surface of the lifting plate. One end of each first spring is fixedly connected to a connecting rod that is slidably connected to the lifting plate. A positioning pressure plate is fixedly connected to the bottom end of each connecting rod. An extension plate is fixedly connected to one side of the lifting plate. An assembly frame is fixedly connected to the top of the extension plate. An assembly plate is snapped into the inside of the assembly frame. A laser lamp is fixedly connected to one side of the assembly plate. The emitting end of the laser lamp is perpendicular to the processing table, and the laser lamp corresponds to the cutting part of the C-shaped ring cutter.
[0007] Preferably, in any of the above solutions, a second spring is fixedly connected to both the left and right sides of the assembly frame, and a snap-fit pin is fixedly connected to the end of the second spring away from the assembly frame. Both snap-fit pins pass through the assembly frame and snap-fit with the assembly plate.
[0008] The top surface of the extension plate is fixedly connected with a number of symmetrically arranged positioning pins, all of which are located inside the assembly frame and are inserted into one side of the assembly plate.
[0009] Two vertically arranged guide rods are fixedly connected to the top surface of the lifting plate, and both guide rods are slidably connected to the L-shaped connecting plate.
[0010] The L-shaped connecting plate has two symmetrically arranged stiffening plates fixedly connected inside, and the cylinder is located between the two stiffening plates.
[0011] The top surface of the lifting plate has two symmetrically arranged clearance slots, which correspond to two connecting rods respectively.
[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When trimming school uniform fabric, first place the fabric on the processing table, turn on the laser light, and the laser light emits a laser beam perpendicular to the processing table and corresponding to the cutting part of the C-shaped ring knife, forming a clear positioning mark line on the fabric. The worker adjusts the fabric position according to this mark line to complete the initial positioning. Then, the cylinder is activated, and the output end of the cylinder pushes the lifting plate downward. The lifting plate drives the connecting rod and the positioning pressure plate to move down synchronously. After the positioning pressure plate contacts the fabric, the connecting rod slides inside the lifting plate, and the first spring is compressed. Using the elastic force of the first spring, the positioning pressure plate is pressed tightly against the fabric, completing the fixation of the fabric. At this time, the C-shaped ring knife can perform the trimming operation on the fabric. The laser beam emitted by the laser light provides accurate visual positioning marks, solving the problem of positioning deviation caused by visual errors in traditional scale markings; at the same time, with the help of the cylinder-driven and first spring-elastic positioning pressure plate, the fabric can be stably and tightly fixed, avoiding displacement of the fabric due to vibration or external force during the cutting process. The combination of these two methods significantly improves positioning accuracy, ensures the accuracy of edge cutting, reduces fabric waste and defective products caused by inaccurate positioning, and improves the quality of school uniform production.
[0013] 2. When installing the assembly plate, align it with the slot in the assembly frame and insert it. During insertion, the assembly plate presses against the locking pin, compressing the second spring. When the locking hole on the assembly plate aligns with the locking pin, the second spring extends, pushing the locking pin into the locking hole, thus securing the assembly plate to the assembly frame. Simultaneously, the positioning pin on the top surface of the extension plate inserts into the positioning hole on one side of the assembly plate, further positioning it. To disassemble the assembly plate, simply pull the locking pin outwards, compressing the second spring and disengaging it from the locking hole, allowing the assembly plate to be removed from the assembly frame. Utilizing the locking structure of the second spring and the locking pin, along with the positioning pin, facilitates convenient assembly and disassembly between the assembly plate and the assembly frame, ensuring accurate positioning of the assembly plate and thus guaranteeing the laser light's positioning precision. This design allows for quick replacement of assembly plates with different laser light specifications to suit various school uniform styles and trimming requirements, enhancing the equipment's flexibility and adaptability to different production scenarios and reducing equipment adjustment time and labor costs.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.
[0017] like Figures 1 to 5 As shown, a school uniform production positioning and trimming structure includes a base 1. A processing table 2 is fixedly installed on the top surface of the base 1 by bolts. A C-shaped ring knife 3 is fixedly connected to one side of the base 1. The processing table 2 is located inside the C-shaped ring knife 3. An L-shaped connecting plate 4 is fixedly installed on the frame part of the C-shaped ring knife 3 by bolts. A cylinder 5 is fixedly connected inside the L-shaped connecting plate 4. A lifting plate 6 is fixedly connected to the output end of the cylinder 5. Two symmetrically arranged first springs 7 are fixedly connected to the top surface of the lifting plate 6. A connecting rod 8 that is slidably connected to the lifting plate 6 is fixedly connected to one end of each first spring 7. A positioning pressure plate 9 is fixedly connected to the bottom end of each connecting rod 8. An extension plate 10 is fixedly connected to one side of the lifting plate 6. An assembly frame 11 is fixedly connected to the top of the extension plate 10. An assembly plate 12 is snapped into the inside of the assembly frame 11. A laser lamp 15 is fixedly connected to one side of the assembly plate 12. The emitting end of the laser lamp 15 is perpendicular to the processing table 2, and the laser lamp 15 corresponds to the cutting part of the C-shaped ring knife 3.
[0018] As an optional technical solution of this utility model, second springs 13 are fixedly connected to both the left and right sides of the assembly frame 11. A locking pin 14 is fixedly connected to the end of the second spring 13 away from the assembly frame 11. Both locking pins 14 penetrate the assembly frame 11 and engage with the assembly plate 12, enabling quick locking and fixing of the assembly plate 12 to the assembly frame 11. When installing the assembly plate 12, the locking pin 14 automatically inserts into the corresponding hole of the assembly plate 12 under the elastic action of the second spring 13, completing the fixing without the need for additional tools. During disassembly, simply pull the locking pin 14 outward to compress the second spring 13, and the assembly plate 12 can be easily removed. This structure not only simplifies the assembly and disassembly process of the assembly plate 12, but also ensures a tight fit between the locking pin 14 and the assembly plate 12 through the continuous elastic force of the second spring 13, preventing the assembly plate 12 from loosening during equipment operation, ensuring the positioning stability of the laser lamp 15, and thus maintaining the trimming accuracy.
[0019] The top surface of the extension plate 10 is fixedly connected with several symmetrically arranged positioning pins 19. These positioning pins 19 are all located inside the assembly frame 11 and are inserted into one side of the assembly plate 12. During installation, the positioning pins 19 are precisely inserted into the holes on one side of the assembly plate 12. This design allows for precise positioning of the assembly plate 12, preventing lateral or angular deviations during the snap-fit process and ensuring that the laser light 15 on the assembly plate 12 is always in the preset positioning position, maintaining a corresponding relationship with the cutting part of the C-shaped ring blade 3.
[0020] Two vertically arranged guide rods 16 are fixedly connected to the top surface of the lifting plate 6. Both guide rods 16 are slidably connected to the L-shaped connecting plate 4. When the cylinder 5 drives the lifting plate 6 to move up and down, the guide rods 16 can provide stable motion trajectory constraints for the lifting plate 6. This can prevent the lifting plate 6 from swaying or tilting during the lifting process, ensuring that the lifting plate 6 drives the positioning pressure plate 9 to move down smoothly, so that the positioning pressure plate 9 can be evenly pressed onto the fabric surface, preventing wrinkles or displacement of the fabric due to uneven local pressure caused by the displacement of the lifting plate 6.
[0021] The L-shaped connecting plate 4 has two symmetrically arranged stiffening plates 17 internally fixedly connected, with the cylinder 5 located between the two stiffening plates 17. This significantly enhances the structural strength and load-bearing capacity of the L-shaped connecting plate 4. Since the cylinder 5 generates a certain amount of impact and vibration during operation, the stiffening plates 17 can disperse the force exerted by the cylinder 5 on the L-shaped connecting plate 4, preventing deformation or cracking of the L-shaped connecting plate 4 due to long-term stress. This ensures that the cylinder 5 remains in a stable installation position and does not affect the accuracy of its drive of the lifting plate 6.
[0022] Two symmetrically arranged clearance grooves 18 are provided through the top surface of the lifting plate 6. The two clearance grooves 18 correspond to the two connecting rods 8 respectively. When the connecting rods 8 move with the lifting plate 6 and slide along the lifting plate 6, the clearance grooves 18 can provide sufficient movement space for the connecting rods 8, avoiding friction or jamming between the connecting rods 8 and the lifting plate 6 due to movement interference.
[0023] A school uniform production positioning and trimming structure, the working principle of which is as follows: 1): When trimming the edges of school uniform fabric, first place the fabric on the processing table 2, turn on the laser lamp 15, and the laser lamp 15 emits a laser beam that is perpendicular to the processing table 2 and corresponds to the cutting part of the C-shaped ring knife 3, forming a clear positioning mark line on the fabric. The worker adjusts the position of the fabric according to the mark line to complete the initial positioning.
[0024] 2): Then start cylinder 5. The output end of cylinder 5 pushes the lifting plate 6 to move downward. The lifting plate 6 drives the connecting rod 8 and the positioning pressure plate 9 to move downward in sync.
[0025] 3): After the positioning plate 9 comes into contact with the fabric, the connecting rod 8 slides inside the lifting plate 6, and the first spring 7 is compressed. Using the elastic force of the first spring 7, the positioning plate 9 is pressed tightly onto the fabric, thus completing the fixation of the fabric.
[0026] In summary, this school uniform production positioning and trimming structure involves placing the fabric on the processing table 2 and turning on the laser lamp 15. The laser lamp 15 emits a laser beam perpendicular to the processing table 2 and corresponding to the cutting part of the C-shaped ring knife 3, forming a clear positioning mark line on the fabric. The worker adjusts the fabric position according to this mark line to complete the initial positioning. Then, the cylinder 5 is activated, and the output end of the cylinder 5 pushes the lifting plate 6 downward. The lifting plate 6 drives the connecting rod 8 and the positioning pressure plate 9 to move downward simultaneously. After the positioning pressure plate 9 contacts the fabric, the connecting rod 8 slides within the lifting plate 6, and the first spring 7 is compressed. Using the elastic force of the first spring 7, the positioning pressure plate 9 is pressed tightly against the fabric, completing the fixation of the fabric. At this time, the C-shaped ring knife 3 can perform the trimming operation on the fabric. Laser light 15 emits a laser beam to provide precise visual positioning marks, solving the problem of positioning deviation caused by visual errors in traditional scale markings. Simultaneously, the positioning pressure plate 9, driven by cylinder 5 and elastically supported by the first spring 7, stably and tightly fixes the fabric, preventing displacement due to vibration or external force during cutting. The combination of these two features significantly improves positioning accuracy, ensures accurate edge cutting, reduces fabric waste and defective products caused by inaccurate positioning, and improves the quality of school uniform production. When installing the assembly plate 12, it is aligned with the slot in the assembly frame 11 and inserted. During insertion, the assembly plate 12 presses against the locking pin 14, compressing the second spring 13. When the locking hole on the assembly plate 12 aligns with the locking pin 14, the second spring 13 extends, pushing the locking pin 14 into the locking hole, completing the locking and fixing of the assembly plate 12 to the assembly frame 11. Simultaneously, the positioning pin 19 on the top surface of the extension plate 10 is inserted into the positioning hole on one side of the assembly plate 12, further positioning the assembly plate 12. To disassemble the assembly plate 12, simply pull the locking pin 14 outwards to compress the second spring 13, causing the locking pin 14 to disengage from the locking hole of the assembly plate 12, allowing the assembly plate 12 to be removed from the assembly frame 11. The locking structure of the second spring 13, the locking pin 14, and the insertion positioning of the positioning pin 19 enable convenient assembly and disassembly between the assembly plate 12 and the assembly frame 11, ensuring the accurate positioning of the assembly plate 12 after installation, thereby guaranteeing the positioning accuracy of the laser light 15. This design facilitates the quick replacement of the assembly plate 12 with different specifications of laser lights 15 according to different school uniform styles and trimming requirements, improving the flexibility and adaptability of the equipment to different production scenarios and reducing the time and labor costs of equipment adjustments.
