Description

Technical Field

[0001] The utility model relates to the technical field of clothing production, and more specifically to a cloth edge cutting device for preventing burrs. Background Art

[0002] Chinese Patent Authorization Announcement No.: CN212199788U provides a cloth slitting device for clothing production that prevents the generation of burrs. The scheme uses the meshing connection of the first fixed block and the second fixed block to enable the mounting rod to drive the connecting block to rotate, thereby driving the connecting plate and the buffer pad to rise and fall through the movable rod to press the cloth tightly, so as to avoid the loosening of the cloth during slitting and the generation of burrs. By pulling the adjusting rod, the mounting block and the cutting blade are stably lifted and lowered under the action of the connecting rod with a "C"-shaped structure in the longitudinal section, so as to perform cloth slitting, so as to ensure stable cutting. When the blade needs to be replaced, the pressing block is manually pressed to rotate the adjustment block with a groove-shaped structure on the left and right sides, thereby driving the limit rod to extend and retract inside the mounting block, so as to facilitate the loading and unloading of the cutting blade, thereby achieving the purpose of facilitating the replacement of the blade.

[0003] However, this solution sets up a structure that is convenient for tool replacement, but the blade used for cutting needs to be replaced once it is worn, which will inevitably lead to an increase in processing costs and waste of materials, which is not conducive to the long-term development of production. Therefore, in order to solve the above problem, a cloth trimming device that prevents burrs is proposed. Utility Model Content

[0039] Clothing is one of the essential daily necessities for people. In the process of clothing production, rolled cloth needs to be cut into required sizes using a slitting device to help people produce high-quality clothing to meet people's needs. During the cloth cutting process, burrs are easily generated at the incision, which affects the appearance of the cloth. This solution is provided with an anti-burr component. Through the setting of the liquid storage tank 704 and the extrusion tube 705, cutting fluid can be applied to the cutting line before the cloth is cut. Cutting fluid is an auxiliary tool for sewing and cloth cutting. It is usually a liquid that can be applied to the cutting line of the cloth to help fix the fiber and reduce the generation of burrs. The main function of the cutting fluid is A thin film is formed on the cutting line of the cloth to keep the fibers tightly combined and reduce the looseness and shedding of the fibers, which helps prevent the cloth from burring or tearing during the cutting process. The principle of using the cutting fluid is the existing technology. In addition, the present solution is set up through the sharpener body 706 and the columnar whetstone 707, which can grind the cutting knife 602 after cutting, so that the user can regularly grind the cutting knife 602 during the cutting process to maintain the sharpness of the cutting knife 602, which helps to reduce the burrs generated during cutting. Compared with the existing solution of regularly replacing the cutting knife, the present solution is more cost-effective to regularly grind the cutting knife 602.

[0040] See also Figure 1-2 The cutting assembly 6 also includes a first electric push rod 601, which is installed on the bracket 2, and the output end of the first electric push rod 601 is fixedly connected to the cutting knife 602. The cutting assembly 6 also includes a pair of symmetrical limiting columns 603, which are fixedly connected to the inner end of the bracket 2, and the two ends of the cutting knife 602 are respectively slidably connected to the pair of limiting columns 603.

[0041] In this solution, when cutting the cloth, the user can place the cloth on the processing table 1. The guide plate 5 can help the user to align the cloth. The user places the cutting line of the cloth on the upper end of the cutting hole 3 so that the cutting line coincides with the cutting hole 3. By starting the first electric push rod 601 to push downward, the cutting knife 602 is driven to move downward. The cutting knife 602 penetrates the cutting hole 3 to complete the cutting of the cloth. During the movement of the cutting knife 602, it slides on a pair of limit columns 603, which can improve the stability of the movement of the cutting knife 602.

[0042] See also Figure 3-5The anti-burr component 7 also includes a pair of support plates 711, a first servo motor 712 and a screw rod 713. The pair of support plates 711 are respectively fixedly connected to the two ends of the processing table 1, and the two ends of the screw rod 713 are respectively rotatably connected to the pair of support plates 711. The first servo motor 712 is installed on the support plate 711, and the output end of the first servo motor 712 is fixedly connected to the screw rod 713. The anti-burr component 7 also includes a base 701, the base 701 matches the movable hole 4, and the base 701 passes through the movable hole 4. The upper and lower ends of the base 701 extend to the upper and lower sides of the processing table 1 respectively. One end of the base 701 is fixedly connected with a screw sleeve 710 matching the screw rod 713, and the screw sleeve 710 is installed At the outer end of the screw rod 713, a second electric push rod 702 is installed at one end of the base 701 close to the cutting hole 3, and the output end of the second electric push rod 702 is fixedly connected to a mounting block 703, and a liquid storage tank 704 is installed on the mounting block 703. The extrusion tube 705 is installed at the lower end of the mounting block 703, and the extrusion tube 705 is communicated with the liquid storage tank 704. The sharpener body 706 is installed on the base 701, and a second servo motor is installed in the inner cavity of the sharpener body 706. The output end of the second servo motor passes through the side wall of the sharpener body 706 and is fixedly connected to a cylindrical whetstone 707. The bottom end of the sharpener body 706 is fixedly connected to a frame 708, and a matching collection box 709 is installed on the frame 708.

[0043] Before starting the first electric push rod 601 to cut the cloth, the user can first start the first servo motor 712 to drive the screw rod 713 to rotate, thereby driving the screw sleeve 710 and the base 701 to slide in the movable hole 4, and the base 701 drives the liquid storage tank 704 and the extrusion tube 705 to pass over the cloth. The liquid storage tank 704 is filled with cutting fluid, and the extrusion tube 705 passes along the cutting line of the cloth and squeezes the cutting fluid onto the cutting line, thereby reducing the generation of cutting burrs during the cutting process. When the cutting assembly 6 as a whole reaches the other end of the movable hole 4, the user can cut the cloth through the cutting assembly 6. After the cutting knife 602 passes through the cutting hole 3 and reaches the lower side of the processing table 1, the blade of the cutting knife 602 will be inserted and squeezed between the columnar grindstone 707 and the sharpener body 706. At this time, the user starts the second servo motor to drive the columnar grindstone 707 to rotate. The rotating cylindrical grindstone 707 can grind the blade of the cutting knife 602, and then the user can start the first servo motor 712 to rotate in the opposite direction, driving the screw sleeve 710 and the base 701 to return along the original path of the movable hole 4. During the return process, the sharpener body 706 and the cylindrical grindstone 707 can grind the entire blade of the cutting knife 602. In order to prevent the mounting block 703 from being blocked by the cutting knife 602 during movement, before the first servo motor 712 is reversed, the second electric push rod 702 will automatically shrink, thereby driving the mounting block 703 to move backward. After moving backward, the mounting block 703 is distanced from the cutting knife 602, so it will not be blocked by the cutting knife 602. When the cylindrical grindstone 707 grinds the cutting knife 602, the waste generated by grinding will fall into the collection box 709 for collection, so that the user can centrally process the cutting waste.

[0044] Working principle:

[0045] When cutting the cloth, the user can place the cloth on the processing table 1, place the cutting line of the cloth at the upper end of the cutting hole 3, so that the cutting line coincides with the cutting hole 3, and then start the first servo motor 712 to drive the screw rod 713 to rotate, thereby driving the screw sleeve 710 and the base 701 to slide in the movable hole 4, and the base 701 drives the liquid storage tank 704 and the extrusion tube 705 to pass over the cloth. The liquid storage tank 704 is filled with cutting fluid, and the extrusion tube 705 passes along the cutting line of the cloth and squeezes the cutting fluid onto the cutting line. When the cutting assembly 6 as a whole reaches the other end of the movable hole 4, the user starts the first electric push rod 601 to push downward, driving the cutting knife 602 to move downward, and the cutting knife 602 passes through the cutting hole 3 to complete the cutting of the cloth. After the cutting knife 602 passes through the cutting hole 3 and reaches the lower side of the processing table 1, the blade of the cutting knife 602 will be inserted and squeezed between the columnar grindstone 707 and the sharpener body 706. The user starts the second servo motor to drive the cylindrical grindstone 707 to rotate. The rotating cylindrical grindstone 707 can grind the back of the cutting knife 602. Then the user starts the first servo motor 712 to rotate in the opposite direction, driving the screw sleeve 710 and the base 701 to return along the original path of the movable hole 4. During the return process, the sharpener body 706 and the cylindrical grindstone 707 can grind the entire back of the cutting knife 602. In order to prevent the mounting block 703 from being blocked by the cutting knife 602 during the movement, before the first servo motor 712 reverses, the second electric push rod 702 will automatically shrink, thereby driving the mounting block 703 to move backward. After moving backward, the mounting block 703 is distanced from the cutting knife 602, so it will not be blocked by the cutting knife 602. When the cylindrical grindstone 707 grinds the cutting knife 602, the waste generated by the grinding will fall into the collection box 709 for collection, so that the user can centrally process the cutting waste.
