Description

Technical Field

[0001] The utility model relates to the field of cloth cutting, in particular to a positioning structure of a cloth cutting machine. Background Art

[0002] When cutting the cloth, the operator places the cloth on the processing platform and then installs the appropriate cutter head. At this time, through the positioning structure on the cutting machine, the driving motor drives the slider to move on the guide rail, and the sliding drives the installed cutter head to move and cut the cloth. The positioning structure can design the cutting path through computer control software to achieve the effect of cutting the cloth.

[0003] Currently, when a cutting machine is used to cut cloth, the cutter head may cause the cloth to move slightly during the movement and cutting process, which may cause the cloth to fold or wrinkle. Continuing to cut will cause the cut pattern to deviate, thereby affecting the cutting quality. Therefore, a positioning structure for a cloth cutting machine is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and avoid the problem of poor cutting effect, the utility model proposes a positioning structure for a cloth cutting machine.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a positioning structure of a cloth cutting machine, comprising a processing table, a conveyor belt is provided on the top of the processing table, a front and rear guide rail is slidably connected to the surface of the processing table, a left and right guide rail is slidably connected to the surface of the front and rear guide rails, a cutting head is fixedly connected to the front end of the left and right guide rails, a limiting component is provided on the rear side of the top end of the processing table, and a pressing component is provided on the bottom of the front and rear guide rails;

[0006] The limiting component includes two vertical rods fixedly installed on the left and right sides of the top of the processing table, the surfaces of the vertical rods are slidably connected to sliders, the ends of the sliders away from the edge of the processing table are fixedly installed with pressure blocks, and the surfaces of the vertical rods are wound with a pressure spring.

[0007] Preferably, the bottom end of the pressing block is in adaptive contact with the top end of the conveyor belt, the bottom end of the pressure spring 1 is fixedly mounted on the top end of the processing table, and the top end of the pressure spring 1 is fixedly mounted on the bottom end of the slider. Under the action of the elastic force of the pressure spring 1 itself, the pressing block will be driven to move downward. At this time, the pressing block presses the cloth on the surface of the conveyor belt, and then pulls the cloth in front. At this time, the front and back sides of the cloth are pulled and straightened.

[0008] Preferably, the clamping assembly includes two pressure springs fixedly installed on the left and right sides of the bottom ends of the front and rear guide rails, a presser foot is fixedly installed on the bottom ends of the two pressure springs, an electromagnet is fixedly installed on the bottom ends of the front and rear guide rails, a magnetic block is fixedly installed on the top end of the presser foot, the internal sliding connection of the presser foot is connected to a driven rod, a bottom groove is provided at the bottom end of the presser foot, a buffer spring is fixedly connected to the surface of the driven rod, a push rod is hinged to the top end of the driven rod, a hollow rod is fixedly installed at the bottom ends of the front and rear guide rails, the internal sliding connection of the bottom end of the hollow rod is connected to a solid rod, a slot is provided on the surface of the solid rod close to the driven rod, and a block is connected to the internal sliding connection of the hollow rod close to the driven rod.

[0009] Preferably, the adjacent ends of the electromagnet and the magnetic block are opposite magnetic poles. The operator can control the presser foot to be energized. At this time, the electromagnet attracts the magnetic block and drives the presser foot to move upward. At this time, the presser foot no longer presses the cloth, so that the cloth can be removed easily. The bottom end of the presser foot is slidably connected to the top of the conveyor belt.

[0010] Preferably, the bottom end of the driven rod is adapted to be clamped inside the bottom groove, the bottom end of the driven rod and the bottom end of the presser foot are adapted to be flush, and the end of the buffer spring away from the driven rod is fixedly installed on the top end of the presser foot. When the presser foot moves downward to press the fabric, the driven rod moves upward under the reaction force until the driven rod is clamped inside the bottom groove, and the bottom end of the driven rod is flush with the bottom end of the presser foot, which will not affect the presser foot's pressing and smoothing of the fabric.

[0011] Preferably, the bottom end of the solid rod is fixedly mounted on the top end of the presser foot, the block and the slot are adapted to be engaged, and the end of the push rod away from the driven rod is hinged at the bottom end of the block. When the driven rod moves upward, it pushes the push rod to swing, and as the driven rod gradually approaches the block, the block is pushed by the push rod and is subjected to a component force toward the side away from the driven rod. At this time, the block is pushed and engaged inside the slot, and the solid rod is restricted by the friction force of the block, so that the solid rod cannot continue to slide inside the hollow rod, and the presser foot cannot continue to move downward to avoid over-pressing the cloth, thereby facilitating the cloth to slide on the surface of the conveyor belt and at the bottom of the presser foot.

[0012] The utility model is beneficial in that:

[0013] The utility model provides pressure blocks on both sides of the rear side of the conveyor belt to press on the top of the cloth, and then uses a traction device to pull the cloth to move on the surface of the conveyor belt. At this time, the cloth is straightened by the traction device and the pressure blocks, so that when the cloth is cut, there will be no errors in the cutting pattern due to folding, thereby ensuring detectable quality.

[0014] When the cutter head is driven by the front and rear guide rails to cut the fabric, the presser foot moves downward and presses on the left and right sides of the fabric. At this time, the presser foot can limit the fabric to prevent it from pulling the fabric to move during the cutting process, further ensuring the cutting quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1 —5 provide further details of this application,

[0024] The embodiment of the present application discloses a positioning structure for a cloth cutting machine. Figure 1 A positioning structure for a cloth cutting machine includes a processing table 1, a conveyor belt 2 is provided on the top of the processing table 1, a front and rear guide rail 31 is slidably connected to the surface of the processing table 1, a left and right guide rail 32 is slidably connected to the surface of the front and rear guide rail 31, a cutting head 33 is fixedly connected to the front end of the left and right guide rails 32, a limiting component 4 is provided on the rear side of the top of the processing table 1, and a pressing component 5 is provided at the bottom of the front and rear guide rails 31;

[0025] Reference Figure 1 - Figure 2 The limiting component 4 includes two vertical rods 41 fixedly mounted on the left and right sides of the top of the processing table 1. The surface of the vertical rod 41 is slidably connected to a slider 42. A pressure block 43 is fixedly mounted on the end of the slider 42 away from the edge of the processing table 1. The surface of the vertical rod 41 is wrapped with a pressure spring 44. The bottom end of the pressure block 43 is adapted to contact the top of the conveyor belt 2. The bottom end of the pressure spring 44 is fixedly mounted on the top of the processing table 1, and the top of the pressure spring 44 is fixedly mounted on the bottom end of the slider 42. Under the action of the elastic force of the pressure spring 44 itself, the pressure block 43 will be driven to move downward. At this time, the pressure block 43 presses the cloth on the surface of the conveyor belt 2, and then pulls the cloth in front. At this time, the front and back sides of the cloth are pulled and straightened.

[0026] Reference Figure 3 - Figure 5The pressing assembly 5 includes a second pressure spring 51 fixedly mounted on the left and right sides of the bottom end of the front and rear guide rails 31, a presser foot 52 fixedly mounted on the bottom end of the second pressure spring 51, an electromagnet 53 fixedly mounted on the bottom end of the front and rear guide rails 31, and a magnetic block 54 fixedly mounted on the top end of the presser foot 52. The adjacent ends of the electromagnet 53 and the magnetic block 54 are mutually different magnetic poles. The operator can control the presser foot 52 to be energized. At this time, the electromagnet 53 attracts the magnetic block 54 and drives the presser foot 52 to move upward. At this time, the presser foot 52 no longer presses the cloth, so that the cloth can be removed. The bottom end of the presser foot 52 is slidably connected to the top of the conveyor belt 2, and the inner sliding part of the presser foot 52 The bottom end of the presser foot 52 is provided with a bottom groove 552, and a buffer spring 553 is fixedly connected to the surface of the driven rod 551. The bottom end of the driven rod 551 is adapted to be clamped in the inside of the bottom groove 552, and the bottom end of the driven rod 551 and the bottom end of the presser foot 52 are adapted to be flush. The end of the buffer spring 553 away from the driven rod 551 is fixedly installed on the top of the presser foot 52. When the presser foot 52 moves downward to press the cloth, the driven rod 551 moves upward under the reaction force until the driven rod 551 is clamped in the inside of the bottom groove 552, and the bottom end of the driven rod 551 and the bottom end of the presser foot 52 are flush. The top of the driven rod 551 is hinged with a push rod 554, and the bottom end of the front and rear guide rails 31 is fixedly installed with a hollow rod 555. The bottom end of the hollow rod 555 is internally slidably connected to a solid rod 556. A groove 557 is provided on the surface of the solid rod 556 near the side of the driven rod 551. A block 558 is internally slidably connected to the side of the hollow rod 555 near the side of the driven rod 551. The bottom end of the solid rod 556 is fixedly installed on the top of the presser foot 52, and the block 558 and the groove 557 are adapted to be engaged. The end of the push rod 554 away from the driven rod 551 is hinged to the block 558. At the bottom end, the driven rod 551 pushes the push rod 554 to swing when it moves upward, and as the driven rod 551 gradually approaches the block 558, the block 558 is pushed by the push rod 554 and is subjected to a component force toward the side away from the driven rod 551. At this time, the block 558 is pushed and connected to the inside of the slot 557. At this time, the solid rod 556 is restricted by the friction force of the block 558, so the solid rod 556 cannot continue to slide inside the hollow rod 555. At this time, the presser foot 52 cannot continue to move downward to avoid over-pressing the cloth, so that the cloth can slide on the surface of the conveyor belt 2 and at the bottom of the presser foot 52.

[0027] Working principle: The operator places the cloth on the surface of the conveyor belt 2. At this time, the front side of the cloth is pulled by a traction device such as a traction machine. At this time, the slider 42 slides downward on the surface of the vertical rod 41 under the action of the elastic force of the pressure spring 44. At this time, the slider 42 drives the pressure block 43 to move downward and abut against the cloth on the surface of the conveyor belt 2. At this time, the traction device pulls the cloth, which makes it straight, and the cloth will not be wrinkled during subsequent cutting.

[0028] During the cutting process, the operator first installs the appropriate cutter head 33 on the front end of the left and right guide rails 32. At this time, the presser foot 52 will move downward under the action of the rebound force of the pressure spring 2 51. At this time, the presser foot 52 will drive the solid rod 556 to slide downward inside the hollow rod 555. At this time, the presser foot 52 presses down on the left and right sides of the top of the cloth. When the presser foot 52 contacts the cloth, the driven rod 551 will move upward under the reaction force of the cloth. At this time, the driven rod 551 will push the push rod 554 upward. As the driven rod 551 gradually approaches the block 558, the push rod 554 pushes the block 558 gradually away from the driven rod 551. At this time, the block 558 is pushed by the push rod 554 until it is locked in the inside of the locking groove 557. At this time, the solid rod 556 cannot continue to slide inside the hollow rod 555. That is, the presser foot 52 is now in contact with the surface of the fabric in its current position, preventing the presser foot 52 from excessively pressing the fabric and causing it to be unable to be pulled further. The fabric can then be cut by the cutter head 33.

[0029] When cutting is completed, the operator can control the electromagnet 53 to be energized and attract the magnetic block 54. At this time, the presser foot 52 is driven upward by the attraction, and the presser foot 52 is separated from the cloth. Then the operator can quickly remove the cut cloth.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
