Description

Technical Field

[0001] The invention relates to the technical field of cloth cutting devices, and in particular to a cloth cutting and pressing mechanism in a raw material cutting device for producing slippers. Background Art

[0002] In the prior art, in the mechanized production of slipper fabric cutting, multiple layers of fabric are stacked on a workbench, and a cutting knife of a cutting mechanism cuts while translating along the X-axis and the Y-axis along a cutting trajectory above the workbench. The pressing component of the fabric is an integral pressing roller located outside the cutting trajectory. For the soft fabric of disposable slippers, the cutter needs to rotate and move during cutting. When the cutter moves during cutting, the fabric will be offset or wrinkled in the area around the fabric that is not pressed by the pressing roller due to the influence of the cutting force of the cutting knife, which affects the cutting quality of the fabric as well as the cutting efficiency. Summary of the invention

[0003] Aiming at the problem in the prior art that the disposable slipper fabric is not pressed properly during cutting and is prone to deviation and wrinkling during the cutting process, the present invention provides a fabric cutting and pressing mechanism, in which a follow-up pressing mechanism is arranged on the periphery of the cutting knife of the cutting mechanism to stably press and hold the fabric in the area around the cutting knife to prevent displacement and deviation during cutting.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention provides a cloth cutting and pressing mechanism, comprising a hollow frame assembly, wherein the hollow frame assembly comprises a hollow frame, wherein the hollow frame is fixed on a power seat of the cutting mechanism, wherein the hollow frame comprises a circular top frame and a ring portion extending downward from the periphery of the top frame, wherein a center hole is provided at the center of the top frame for facilitating the passage of a cutting blade component of the cutting mechanism, wherein a plurality of radial sliding grooves are evenly distributed around the top frame, wherein a sliding frame is slidably connected to the interior of the sliding groove, and a pressing component is connected to the sliding frame; wherein the pressing component comprises a pressing swing arm, wherein a pressing surface of the pressing swing arm rotates The cam is connected to the sliding member by a plurality of rollers that are in rolling contact with the cloth. The upper end of the press-material swing arm is connected to the sliding frame in a swinging manner. The sliding frame includes two parallel slide bars, one end of the two slide bars is fixedly connected by a connecting shaft, and the other end of the two slide bars is connected to a T-shaped rod, the top rod of the T-shaped rod is fixed between the two slide bars, and the vertical rod of the T-shaped rod is vertically downwardly arranged. The groove walls on both sides of the sliding groove are respectively provided with slideways for slidingly installing the slide bars. The upper end of the press-material swing arm is rotatably connected to the connecting shaft, and when the press-material swing arm contacts with the cloth, it swings outward around the connecting shaft and opens to the inner side surface to press and tension the cloth.

[0005] The cloth cutting and pressing mechanism of the present invention is installed on the power seat of the cutting mechanism according to the set cutting route, and is synchronously translated with the cutting mechanism to realize dynamic pressing while cutting. When the cutting mechanism smoothly cuts the cloth according to the predetermined cutting route, the outer periphery of the cutter is driven by the hollow frame to press the cloth while cutting through the synchronously moving pressing parts, so as to realize dynamic pressing and prevent the cloth from deflecting or wrinkling under the action of the cutting force, so as to ensure the accuracy of the cutting route. When the cutting mechanism reaches the starting position of the cutting route, the hollow frame drives the pressing swing arm downward under the drive of the power seat, and the pressing swing arm gradually opens toward the periphery and contacts the cloth until the balls on the pressing inclined surface are completely in contact with the cloth, so as to realize pressing around the cutting position.

[0006] Furthermore, the lower part of the inner side surface of the material-pressing swing arm is inclined outwards for contacting the material when opening outwards, the ball bearing is arranged on the inclined surface, the upper part of the inner side surface of each material-pressing swing arm is hinged with a supporting link, and the other end of each supporting link is hingedly connected to a chassis for pre-pressing the cloth, and when the hollow frame moves down with the power seat of the cutting mechanism to press the material, the chassis contacts the cloth in advance to press the material and supports and pushes the material-pressing swing arm to open outwards. In this structure, before the material-pressing surface of the material-pressing swing arm completely contacts the cloth, the chassis first pre-presses the cloth, and supports the material-pressing swing arm to gradually open outwards through the supporting link to achieve pre-pressing.

[0007] In order to facilitate the timely resetting of each pressing component after cutting is completed, a number of upwardly extending spring rods are evenly distributed on the circumference of the upper side of the chassis. The upper ends of the spring rods penetrate upward to the top of the power seat and extend to the top of the power seat. The top ends of the spring rods are provided with springs and pressure caps for guiding the resetting of the chassis.

[0008] To further assist in pressing the material, a rotating mechanism is provided inside the hollow frame, and the rotating mechanism includes a toothed disc rotatably connected to the top inner wall of the hollow frame, a plurality of arc grooves are evenly arranged around the disc surface of the toothed disc, the arc grooves are symmetrically arranged relative to the center of the toothed disc, and the arc ends are radiated toward the periphery, the vertical rod of the T-shaped rod is slidably connected in the arc groove, the teeth of the toothed disc are downwardly arranged and meshingly connected with a plurality of gear shafts, the shaft ends of the gear shafts are rotatably connected to a limiting frame, the outer surface of the limiting frame is fixedly connected to the inner wall of the hollow frame by a plurality of radial connecting plates, the axial direction of the gear shaft corresponds to the central axis of the toothed disc and the outer peripheral wall of the shaft end is connected to a right-angle connecting rod, the other end of the right-angle connecting rod is provided with a horizontal axis, the horizontal axis support is connected to a lifting plate, the lifting plate is vertically arranged and the lower end is fixedly connected to an auxiliary pressing mechanism. In this combination, during the opening of the pressing swing arm, the sliding frame slides radially inward along the sliding groove, driving the T-bar to move synchronously. At the same time, the vertical rod of the T-bar drives the gear plate to rotate, and the gear plate engages with the gear shaft. When the gear shaft rotates, it drives the movement of the right-angle connecting rod to make the lifting plate move obliquely downward, driving the limit frame to rotate and descend, and synchronously driving the auxiliary pressing mechanism to move downward to press the material.

[0009] To facilitate the auxiliary pressing action, the auxiliary pressing mechanism includes a limit plate fixedly connected to the bottom of each lifting plate, a plurality of fixed shafts are fixedly connected to the lower side of the limit plate at equal intervals in the circumferential direction, two radially corresponding rotating inclined grooves are opened on the outer circumference of the fixed shaft, and an insertion rod is slidably connected to the inside of the rotating inclined groove, and a spring frame is fixed on the insertion rod. The spring frame can slide and rise and fall along the rotating inclined groove with the insertion rod, and a return spring is mounted on the fixed shaft on the upper side of the spring frame. The return spring and the limit plate are elastically pressed together, and a roller is rotatably connected to the bottom frame of the spring frame. The roller is used for rolling and compacting the material, and an arc-shaped through hole is provided at the position where the chassis passes through the roller for lifting and lowering.

[0010] The present invention has the following beneficial effects: When the power base of the cutting mechanism moves downward, the power base drives the hollow frame and the material pressing swing arm to move downward synchronously. The material pressing swing arm contacts the material when moving downward, and then the power base continues to move downward to squeeze the material through the chassis. The reaction force generated by the squeezing of the material pushes the chassis and the material pressing swing arm upward. When the chassis is pushed upward by the material, it pushes the material pressing swing arm through the supporting connecting rod, so that the material pressing swing arm drives the sliding frame to slide radially in the sliding groove. Then, when the chassis continues to move upward, the supporting connecting rod pushes the lower contact part of the material pressing swing arm to expand outward on the surface of the material, and an outward force can be applied to the material before the cutter contacts the material. This force can make the cutting area around the material in a taut state, reduce the lateral force generated by the cutter on the material when cutting, keep the material in a relatively stable state, help reduce the deviation and wrinkling of the material caused by the force of the tool when cutting, and reduce the cutting deviation caused by wrinkling of the material during the cutting process.

[0011] 2. In the present invention, when the material pressing swing arm is pushed by the supporting connecting rod and drives the sliding frame to slide outward inside the sliding groove, the sliding of the sliding frame will drive the T-shaped rod to slide synchronously, and when the T-shaped rod slides, it will slide synchronously in the arc groove and drive the gear plate to rotate by sliding inside the arc groove, and when the gear plate rotates, it will drive multiple gear shafts to rotate, and when the gear shafts rotate, they will drive the lifting plate to translate downward through the right-angle connecting rod, and when the multiple lifting plates translate downward, they will drive the limit plate to translate downward, and when the limit plate slides downward, the spring frame at the bottom of the limit plate will move downward synchronously, and then when the limit plate continues to move downward, the downward movement of the limit plate will squeeze the spring frame through the fixed shaft, and the spring frame will be pressed downward. After the spring frame is squeezed, the two insertion rods inside the spring frame will slide inside the inclined groove and drive the spring frame to rotate under the guidance of the inclined groove. When the spring frame rotates, it will drive the roller at the bottom to rotate synchronously. At this time, the spring frame drives the roller to pass through the arc-shaped through hole on the chassis to contact the surface of the cloth. Then, when the cutter moves to cut the material, the roller and the material are in rolling contact and press the material. It can also prevent the cloth from moving during the cutting process of the cutter, help maintain the flatness of the material, reduce the material in the cutting area due to excessive friction resistance during the cutting process of the cutter, resulting in distortion or tearing, thereby improving the precision and accuracy of cutting.

[0015] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0016] like Figure 1 - Figure 6As shown, the cloth cutting and pressing mechanism of the present invention includes a hollow frame assembly 3, which is the installation base of the cloth cutting and pressing machine as a whole, and specifically includes a hollow frame 301. The hollow frame 301 is fixed on the power seat 2 of the cutting mechanism and moves synchronously therewith. The power seat 2 is slidably installed on the cutting mechanism mounting seat 1. Before the cutting mechanism starts working, the power seat 2 can move up and down along the mechanism mounting seat 1 to drive the carrier knife downward to contact the cloth, and at the same time, the hollow frame assembly 3 also moves downward as a whole. The hollow frame 301 in this embodiment includes a circular top frame and a ring portion extending downward from the periphery of the top frame. A center hole is provided in the center of the top frame of the hollow frame 301 for the cutting knife component of the cutting mechanism to pass through. A plurality of radial sliding grooves 302 are evenly distributed around the top frame. A sliding frame 303 is slidably connected inside the sliding groove 302. A pressing component 4 is connected to the sliding frame. The pressing component 4 includes a pressing swing arm 401. A plurality of balls 409 that roll in contact with the cloth are rotatably connected to the pressing surface of the pressing swing arm 401. The upper end of the pressing swing arm 401 is connected to the sliding frame 303. Swing connection, the sliding frame 303 includes two parallel sliding bars 303A, one end of the two sliding bars 303A is fixedly connected by a connecting shaft 303B, the other end of the two sliding bars 303A is connected with a T-shaped rod, the top rod of the T-shaped rod is fixed between the two sliding bars 303A, the vertical rod of the T-shaped rod is vertically arranged downward, and the groove walls on both sides of the sliding groove 302 are respectively provided with slideways 302A for slidingly installing the sliding bars, the upper end of the pressing swing arm 401 is rotatably connected to the connecting shaft, and when the pressing swing arm 401 contacts with the cloth, it swings outward around the connecting shaft and opens to the inner side surface to press and tension the cloth.

[0017] In this embodiment, the lower part of the inner side surface of the pressing swing arm 401 is inclined outward for contacting and pressing the material when it is opened outward, and the ball 409 is arranged on the inclined surface. The upper part of the inner side surface of each pressing swing arm 401 is hinged with a supporting link 404, and the other end of each supporting link 404 is hingedly connected to a chassis 405 for pre-pressing the cloth. When the hollow frame 301 moves downward with the power seat 201 of the cutting mechanism to press the material, the chassis 405 contacts the cloth in advance to press the material and pushes the pressing swing arm 401 to open outward through the supporting link support 404. When the power seat 2 moves downward, the power seat 2 drives multiple material pressing swing arms 401 to move downward synchronously. The material pressing swing arms 407 will come into contact with the material when moving downward. Then, when the power seat 201 continues to move downward, the cloth will be pre-pressed through the chassis 405. The reaction force generated by the pressure on the material will push the chassis 405 and the material pressing swing arms 401 upward to push the material pressing swing arms 401 to expand toward the periphery.

[0018] There are several upwardly extending spring rods 407 evenly distributed around the upper side of the chassis 405. The upper ends of the spring rods 407 pass through the hollow frame 301 and the power seat 2 in sequence and extend to the top of the power seat 2. The top of the spring rods 407 is provided with a spring 408 and a pressure cap for guiding the reset chassis 405.

[0019] The hollow frame 301 is provided with a rotating mechanism 5, which includes a toothed disc 501 rotatably connected to the top inner wall of the hollow frame 301, and a plurality of arc grooves 502 are evenly arranged around the disc surface of the toothed disc 501, and the plurality of arc grooves 502 are symmetrically arranged relative to the center of the toothed disc 501 and the arc ends are projected toward the periphery, and the vertical rod of the T-shaped rod 304 is slidably connected in the arc groove 502, and the toothed portion of the toothed disc 501 is downwardly arranged and meshedly connected with a plurality of gear shafts 503, and the gear shafts 503 are connected to the toothed disc 501. The shaft end of 03 is rotatably connected to the limit frame 504, and the outer surface of the limit frame 504 is fixedly connected to the inner wall of the hollow frame 301 through a plurality of radial connecting plates. The axial direction of the gear shaft 503 corresponds to the central axis of the gear disk and the outer peripheral wall of the shaft end is connected to a right-angle connecting rod (506), and the other end of the right-angle connecting rod (506) is provided with a horizontal axis (506A), and the horizontal axis (506A) is supported and connected to a lifting plate 505, and the lifting plate 505 is vertically arranged and the lower end is fixedly connected to an auxiliary pressing mechanism 6. When the pressing swing arm 401 is pushed by the supporting connecting rod 404 to drive the sliding frame 303 to slide outward inside the sliding groove 302, the sliding of the sliding frame 303 will drive the T-shaped rod 304 to slide synchronously. When the T-shaped rod 304 slides, it will slide in the arc groove 502 and drive the gear plate 501 to rotate by sliding inside the arc groove 502. When the gear plate 501 rotates, it will drive multiple gear shafts 503 to rotate. When the gear shafts 503 rotate, they will drive the lifting plate 505 to deviate downward through the swing of the right-angle connecting rod.

[0020] The auxiliary pressing mechanism 6 includes a limit plate 601 fixedly connected to the bottom of each lifting plate 505, and a plurality of fixed shafts 602 are fixedly connected to the lower side of the limit plate 601 at equal intervals in the circumferential direction. The outer periphery of the fixed shaft 602 is provided with two radially corresponding rotating inclined grooves, and an insertion rod 604 is slidably connected inside the rotating inclined groove. A spring frame 603 is fixed on the insertion rod, and the spring frame 603 can be slid and lifted along the rotating inclined groove with the insertion rod. A return spring is mounted on the fixed shaft on the upper side of the spring frame 603, and the return spring is elastically pressed onto the limit plate 601. A roller is rotatably connected to the bottom frame of the spring frame 603, and the roller is used for rolling and compacting the material. An arc-shaped through hole 406 is provided on the chassis 405 at a position corresponding to the roller lifting and lowering. After the spring frame 603 moves downward and is squeezed, the two insertion rods 604 inside the spring frame 603 will slide inside the inclined groove and drive the spring frame 603 to rotate under the guidance of the inclined groove. When the spring frame 603 rotates, it will drive the roller at the bottom to rotate synchronously. At this time, the roller will pass through the arc-shaped through hole 406 and contact the surface of the material to achieve rolling pressing.

[0021] The cloth cutting and pressing mechanism and the cutting mechanism of the present invention perform synchronous translation and lifting movements as a whole. The translation drive unit and the lifting drive unit are not involved in the Chinese text. They are conventional X-axis, Y-axis and Z-axis translation drive structures. The cloth cutting and pressing mechanism of the present application is limited to the realization of the pressing function when cutting cloth. During the fabric cutting process, the cloth to be cut is laid on the workbench. It can be laid in multiple layers according to the thickness of the cloth and the cutting ability of the carrier knife. The entire periphery is pressed as a whole in the non-cutting area by the limiting roller. Then the power seat is translated to the starting position of the cutting route. When the cutting mechanism smoothly cuts the cloth according to the predetermined cutting route, the space frame assembly 3 reaches the loading position at the same time as the power seat. The downward movement of the power seat 2 will drive multiple material pressing swing arms 401 to move downward synchronously. The material pressing swing arms 401 will contact the material when moving downward, and then the material will be squeezed through the chassis 405 when the power seat 2 continues to move downward. The reaction force generated by the squeezing of the material will push the chassis 405 and the material pressing swing arms 401 upward. When the chassis is pushed upward by the material, it will push the material pressing swing arms 401 through the supporting connecting rods 404, so that the material pressing swing arms 401 drive the sliding frame 303 to slide inside the sliding groove 302, and then the chassis 405 When the upward movement continues, the upward movement of the chassis 405 will push the material pressing swing arm 401 to expand outward on the surface of the material through the supporting connecting rod 404, and can apply an outward force to the material before the cutter 204 contacts the material. This force can keep the area around the cutting area of ​​the material in a taut state, which can reduce the lateral force exerted on the material by the cutter 204 when cutting, so that the material remains in a relatively stable state, which helps to reduce the displacement and wrinkling of the material caused by the force of the tool when cutting, and reduce the cutting deviation caused by wrinkles in the material during the cutting process.

[0022] When the pressing swing arm 401 is pushed by the supporting connecting rod 404 and drives the sliding frame 303 to slide outward inside the sliding groove 302, the sliding of the sliding frame 303 will drive the T-shaped rod 304 to slide synchronously. When the T-shaped rod 304 slides, it will slide in the arc groove 502 and drive the gear plate 501 to rotate by sliding inside the arc groove 502. When the gear plate 501 rotates, it will drive multiple gear shafts 503 to rotate. When the gear shaft 503 rotates, it will drive the lifting plate 505 to rotate synchronously through the right-angle connecting rod. Then, when the right-angle rod rotates to the lower dead point of the original position, it will drive the lifting plate 505 to slide downward at the same time. When multiple lifting plates 505 slide downward, they will drive the limit plate 601 to rotate and translate downward at the same time. When the limit plate 601 translates downward, the spring frame 603 at the bottom of the limit plate 601 will reach the arc-shaped through hole 406 of the chassis 405. When the spring frame 603 is squeezed, the two insertion rods 604 inside the spring frame 603 will slide inside the inclined groove and drive the spring frame 603 to rotate under the guidance of the inclined groove. When the spring frame 603 rotates, it will drive the roller at the bottom to rotate synchronously. At this time, the bottom side of the spring frame 603 and the roller 606 will pass through the arc through hole 406 and roll in contact with the surface of the cloth. Then, when the cutter moves and cuts the material, the roller will provide a certain rolling force between the arc through hole 406 and the material, which can also reduce the stringing of the material during the moving and cutting process of the cutter, help maintain the flatness of the material, reduce the distortion or tearing of the cutting area of ​​the material due to excessive friction resistance during the moving and cutting process of the cutter, and improve the precision and accuracy of cutting.
