Technical Field

[0001] The present invention relates to the technical field of pillow core production, and more particularly to automatic pillow core production equipment. Background Art

[0002] During the production process of pillow cores, the pillow cover is usually produced first, and then the filling is added to the pillow cover, thereby realizing the automatic production of the pillow core. Usually, the above two steps are manufactured on different machines, which seriously restricts the efficiency of pillow core production.

[0003] Chinese patent publication number CN111268187A, published on June 12, 2020, is titled "A Continuous Pillow Core Production Apparatus." The application discloses a pillow core production apparatus in which a sealing machine is provided to automatically seal the pillow core after filling it with down, thereby achieving automatic sealing of the pillow core. This solves the problem of manually sealing the pillow core cover after filling it with down in the prior art. Although the above application can improve production efficiency, it still requires the pillow core cover to be prepared in advance and then filled with cotton, and does not achieve a full set of automated production functions for the production of the pillow core cover, the filling of the pillow core cover, and the sealing of the pillow core cover after filling with cotton. Summary of the Invention

[0004] The present invention overcomes the problem in the prior art that, during the pillow core manufacturing process, the pillowcase needs to be made first, then filled with cotton, and finally the pillowcase is sealed; the entire pillow core production process is cumbersome and complicated, which restricts the insufficient production efficiency of the pillow core. The present invention provides an automatic pillow core production equipment, which can realize all the processes of pillowcase production, pillowcase filling, and pillowcase sealing, realizes the automatic production of pillow cores, and improves the production efficiency of pillow cores.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: an automatic pillow core production device, comprising: The pillowcase production assembly includes an upper cloth roller and a lower cloth roller, both of which are wound with cloth; and a sewing assembly sews the edges of the two layers of cloth together; A cotton filling assembly includes a cotton filler and a cotton filling tube, wherein the cotton filling tube is arranged between the two layers of cloth; The sewing and cutting assembly moves along the width direction of the two layers of cloth and includes a sewing device and a cutting device. The sewing device sews two seams at the opening of the two layers of cloth; and the cutting device cuts between the two seams.

[0006] When the present application is in use, the upper cloth roller is wound with the upper layer of cloth, and the lower cloth roller is wound with the lower layer of cloth. The upper and lower layers of cloth overlap to form two layers of cloth, and the cotton filling tube is located between the two layers of cloth. Under the action of the sewing component, the two sides of the two layers of cloth are sewn together, so that the upper and lower layers of cloth form a "sleeve shape". The cotton filling tube then fills cotton into the sleeve-shaped cotton filling tube to fill the pillow core. After the cotton filling is completed, the sewing component sews two seams at the opening of the two layers of cloth, and then uses a cutter to cut between the two seams. One of the two seams is used as the seam edge of the newly made pillow core, and the other is used as the sealing seam edge at one end of the new pillowcase to prepare for the subsequent pillow core production. Therefore, the present application can simultaneously perform the pillow core production, pillowcase filling and pillowcase sealing work, realizing the work of fully automated pillow core production.

[0007] Preferably, the cotton filling assembly further comprises a sliding plate, and the cotton filling tube is arranged on the sliding plate; the sliding plate drives the cotton filling tube to slide back and forth along the length direction of the cotton filling tube.

[0010] The second nip roller group includes a second lower nip roller and a second upper nip roller that can approach each other; the second driving device drives the second lower nip roller or the second upper nip roller to rotate.

[0011] When the pillowcase needs to be cut, the first roller cylinder drives the first upper clamping roller to move downward, so that the first upper clamping roller and the first lower clamping roller are clamped on the upper and lower sides of the two layers of cloth, thereby cooperating with the first upper clamping plate, the first lower clamping plate, the second upper clamping plate and the second lower clamping plate to clamp the two sides of the pillowcase, so that when the sewing and cutting assembly sews and cuts the pillowcase, the edges of the stitched and cut pillowcase can be smoother.

[0012] When the pillowcase at the end is being filled, sewn, or cut, the second lower clamping roller can rotate independently and drive the pillowcase to move, so that the two sides of the pillowcase are sewn first, and the sewn pillowcase is stored between the first clamping roller group and the second clamping roller group. After the sewing and cutting of the pillowcase at the front end are completed, the first lower clamping roller can rotate independently and quickly to send the pillowcase stored between the first clamping roller group and the second clamping roller group to the space between the first upper clamping plate, the first lower clamping plate, the second upper clamping plate, and the second lower clamping plate for filling, sewing, and cutting, thereby improving the efficiency of pillow core production.

[0013] Preferably, the first lower clamping roller and the first upper clamping roller are both provided with a first meshing gear. When the first lower clamping roller and the first upper clamping roller are clamped, the first meshing gears on the first lower clamping roller and the first upper clamping roller mesh with each other for transmission.

[0018] The first annular groove does not affect the conveying of the pillowcase and does not affect the filling of the pillowcase by the filling pipe. The second annular groove does not affect the conveying of the pillowcase and does not affect the filling of the pillowcase by the filling pipe.

[0019] Preferably, the invention further comprises a cloth inserting assembly provided at the outlet of the cotton filling pipe; the cloth inserting assembly comprises: a first transverse movement rod, and a first transverse movement cylinder driving the first transverse movement rod to move along the width direction of the cotton filling tube; A first upper clamping plate and a first lower clamping plate are slidably arranged along the first transverse rod, the first upper clamping plate is connected to the output end of the first upper cylinder, and the first lower clamping plate is connected to the output end of the first lower cylinder; a second transverse movement rod, and a second transverse movement cylinder driving the second transverse movement rod to move along the width direction of the cotton filling tube; A second upper clamping plate and a second lower clamping plate are slidably arranged along the second transverse rod; the second upper clamping plate is connected to the output end of the second upper cylinder, and the second lower clamping plate is connected to the output end of the second lower cylinder.

[0020] By controlling the movement of the first transverse cylinder, the second transverse cylinder, the first upper cylinder, the first lower cylinder, the second upper cylinder, and the second lower cylinder, the first upper plate, the first lower plate, the second upper plate, and the second lower plate can be clamped around the filling tube during filling, tightly clamping the pillowcase and preventing cotton from leaking out during the filling process. When filling is completed, the filling tube retracts, and the first transverse cylinder drives the first transverse rod to move, thereby simultaneously moving the first upper plate and the second lower plate. The second transverse cylinder drives the second transverse rod to move, thereby simultaneously moving the second upper plate and the second lower plate. The first upper plate and the second lower plate are clamped on one side of the pillowcase, and the second upper plate and the second lower plate are clamped on the other side of the pillowcase. When the first upper plate, the second lower plate, the second upper plate, and the second lower plate move away from each other, the pillowcase opening can be tightened and flattened, thereby making the pillowcase opening more flat during sewing. Furthermore, by coordinating the first driving motor and the second driving motor to drive the ultrasonic suturing device and the ultrasonic cutter to rotate, the opening of the pillowcase can be sutured and cut more smoothly.

[0021] Preferably, the first upper splint and the second upper splint are both provided with upper notches; the first lower splint and the second lower splint are both provided with lower notches; when the four splints are combined, the two upper notches and the two lower notches cooperate to form a cotton filling hole, and the cotton filling tube extends into the cotton filling hole to fill the pillowcase with cotton.

[0022] The two upper notches cooperate with the two lower notches to form a cotton filling hole, and the cotton filling tube extends into the cotton filling hole to fill the pillowcase with cotton. Therefore, during the cotton filling process, all openings of the pillowcase can be blocked to prevent cotton from leaking out.

[0023] Preferably, the tailoring assembly further comprises: Upper mounting seat and lower mounting seat, A transverse movement device that drives the upper and lower mounting seats to move synchronously; The suturing device comprises an ultrasonic suturing device rotatably mounted on an upper mounting seat and a suturing wheel rotatably mounted on a lower mounting seat; the edge of the suturing wheel is provided with two suturing convex edges; The cutter includes an ultrasonic cutter rotatably mounted on an upper mounting seat and a cutting wheel rotatably mounted on a lower mounting seat; the edge of the cutting wheel is provided with a cutting edge; The moving track of the cutting edge is between the moving tracks of the two sewing convex edges.

[0024] The present invention provides a stitching and cutting mechanism, both mounted between an upper and lower mounting base. Synchronous movement of the upper and lower mounting bases allows for simultaneous stitching and cutting. Furthermore, during stitching and cutting, the stitching mechanism is positioned at the front of the cutter's movement direction, with the cutting edge's trajectory tracing between the two camming edges, thereby enabling stitching to occur first, followed by cutting.

[0025] Preferably, the traverse device comprises: An upper transverse belt is fixedly provided with an upper transverse plate, an upper mounting seat is slidably provided on the upper transverse plate, and the upper mounting seat moves toward or away from the lower mounting seat; The lower transverse belt is fixedly provided with a lower transverse plate, the lower mounting seat is slidably provided on the lower transverse plate, and the lower mounting seat moves toward or away from the upper mounting seat; The transverse driving assembly includes a main driving rod, a slave driving rod and a transverse motor that drives the main driving rod to rotate. Both ends of the upper transverse belt and the lower transverse belt are connected to the main driving rod and the slave driving rod respectively.

[0026] The lateral motor drives the main drive rod to rotate, and the main drive rod drives the upper lateral belt and the lower lateral belt to move synchronously, thereby synchronously driving the upper lateral plate and the lower lateral plate to move horizontally, and then synchronously driving the upper mounting seat and the lower mounting seat to move horizontally.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present application, the upper cloth roller is wound with the upper layer of cloth, and the lower cloth roller is wound with the lower layer of cloth. The upper and lower layers of cloth overlap to form two layers of cloth, and the cotton filling tube is located between the two layers of cloth. Under the action of the sewing component, the two side edges of the two layers of cloth are sewn together so that the two layers of cloth form a "sleeve shape". Then the cotton filling tube fills cotton into the sleeve-shaped cotton filling tube to fill the pillow core. After the cotton filling is completed, the two seams are sewn at the opening of the two layers of cloth under the action of the sewing component, and then the two seams are cut by the cutter. One of the two seams is used as the seam edge of the newly made pillow core, and the other is used as the sealing seam edge at one end of the new pillowcase to prepare for the subsequent pillow core production. Therefore, the present application can simultaneously carry out the production of the pillow core, the filling of the pillowcase, and the sealing of the pillowcase, thereby realizing the fully automated production of the pillow core.

[0028] In addition, when the pillowcase at the end is being filled, sewn, or cut, the second lower clamping roller can rotate independently and drive the pillowcase to move, so that the two sides of the pillowcase are sewn first, and the sewn pillowcase is stored between the first clamping roller group and the second clamping roller group. After the sewing and cutting of the pillowcase at the front end are completed, the first lower clamping roller can rotate independently and quickly to send the pillowcase stored between the first clamping roller group and the second clamping roller group to the space between the first upper clamping plate, the first lower clamping plate, the second upper clamping plate, and the second lower clamping plate for the next filling, sewing, and cutting, thereby improving the efficiency of pillow core production.

[0039] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 9 As shown, an automatic pillow core production device includes: The pillowcase production assembly 1 includes an upper cloth roller 11 and a lower cloth roller 12, both of which are wound with cloth; a sewing assembly 13 sews the edges of the two layers of cloth together; The cotton filling assembly 2 includes a cotton filler 21 and a cotton filling tube 22, wherein the cotton filling tube 22 is arranged between the two layers of cloth; The sewing and cutting component 3 moves along the width direction of the two layers of cloth, and includes a sewing device and a cutter; the sewing device sews two seams at the opening of the two layers of cloth; and the cutter cuts between the two seams.

[0040] When the present invention is in use, an upper cloth layer 111 is wound around the upper cloth roller 11, and a lower cloth layer 121 is wound around the lower cloth roller 12. The upper cloth layer 111 and the lower cloth layer 121 overlap to form two layers of cloth, with the filling tube 22 positioned between the two layers. Under the action of the sewing assembly 13, the two sides of the two layers of cloth are sewn together, so that the upper and lower layers of cloth form a "sleeve shape." The filling tube 22 then fills the sleeve-shaped filling tube 22 with cotton to fill the pillow core. After the filling is completed, the sewing assembly 3 sews two seams at the opening of the two layers of cloth, and then a cutter cuts between the two seams. One of the two seams serves as the seam edge of the newly made pillow core, and the other serves as the sealing seam edge of one end of the new pillowcase, preparing for the subsequent pillow core production. Therefore, the present invention can simultaneously produce the pillow core, fill the pillowcase with cotton, and seal the pillowcase, achieving fully automated pillow core production.

[0041] In one embodiment, the cotton filling assembly 2 further includes a cotton filling frame 23, on which a sliding plate 24 is slidably provided, and the cotton filling tube 22 is fixedly provided on the sliding plate 24; the sliding plate 24 drives the cotton filling tube 22 to slide back and forth along the length direction of the cotton filling tube 22. Specifically, a cotton filling cylinder 25 is fixedly provided on the cotton filling frame 23, and the setting direction of the cotton filling cylinder 25 is parallel to the cotton filling tube 22. The movable end of the cotton filling cylinder 25 is fixedly connected to the sliding plate 24. Under the action of the cotton filling cylinder 25, the sliding plate 24 is driven to move, so that the sliding plate 24 can drive the cotton filling tube 22 to move along the length direction of the cotton filling tube 22. Since the cotton filling tube 22 needs to move along its own length direction, the connection end of the cotton filling tube 22 and the cotton filler 21 in this application is connected by a hose so that the cotton filling tube 22 can move freely.

[0042] In one embodiment, the sewing assembly 3 is arranged at the outlet of the cotton filling tube 22, so that the sewing assembly 3 can sew and cut the pillowcase after the cotton filling is completed. Figure 8 As shown, the tailoring component 3 also includes: The upper mounting seat 31 and the lower mounting seat 32 can simultaneously move in a horizontal direction perpendicular to the cotton filling tube 22. The upper mounting seat 31 and the lower mounting seat 32 are synchronously moved laterally by a transverse movement device 33.

[0043] The stitching device 34 comprises an ultrasonic stitcher 341 rotatably mounted on the upper mounting seat 31 and a stitching wheel 342 rotatably mounted on the lower mounting seat 32. The edge of the stitching wheel 342 is provided with two stitching flanges 343. In this embodiment, the ultrasonic stitcher 341 and stitching wheel 342 cooperate to achieve ultrasonic stitching. As the cloth passes between the ultrasonic stitcher 341 and stitching wheel 342, the ultrasonic stitcher 341 stitches the upper cloth 111 and the lower cloth 121 together.

[0044] During the suturing process, the ultrasonic suture device 341 is rotatably mounted on the upper mounting base 31. A first drive motor 311 is mounted on the upper mounting base 31. A belt drive is provided between the output end of the first drive motor 311 and the ultrasonic suture device 341, driving the rotation of the ultrasonic suture device 341. This prevents the ultrasonic suture device 341 from operating continuously in one position, extending the service life of the ultrasonic suture device 341 and the suture wheel 342. Correspondingly, a second drive motor is mounted on the lower mounting base 32. A belt drive is provided between the output end of the second drive motor and the suture wheel 342, driving the rotation of the suture wheel 342. During the suturing process, the suture wheel 342 rolls along the two layers of fabric, completing the suture process.

[0045] The cutter 35 comprises an ultrasonic cutter 351 rotatably mounted on the upper mounting seat 31 and a cutting wheel 352 rotatably mounted on the lower mounting seat 32. The cutting wheel 352 has a cutting edge 353. In this embodiment, the ultrasonic cutter 351 and the cutting wheel 352 cooperate to achieve ultrasonic cutting of the cloth. As the cloth passes between the ultrasonic cutter 351 and the cutting wheel 352, the ultrasonic cutter 351 separates the upper cloth 111 from the lower cloth 121.

[0046] During the cutting process, the ultrasonic cutter 351 is rotatably mounted on the upper mounting base 31. A third drive motor 312 is mounted on the upper mounting base 31. A belt drives the ultrasonic cutter 351 through its output end, thereby driving the rotation of the ultrasonic cutter 351. This prevents the ultrasonic cutter 351 from operating continuously in one position, extending the service life of the ultrasonic stitcher 341 and stitching wheel 342. Correspondingly, a fourth drive motor is mounted on the lower mounting base 32. A belt drives the cutting wheel 352 through its output end, thereby rotating the cutting wheel 352. During the cutting process, the cutting wheel 352 rolls along the two layers of fabric, effectively cutting the fabric.

[0047] The present invention provides a method for synchronizing the stitching and cutting functions by positioning the stitcher 34 and the cutter 35 between the upper and lower mounting bases 31 and 32. The stitcher 34 and the cutter 35 move synchronously with each other, achieving synchronization of the stitching and cutting functions. Furthermore, during stitching and cutting, the stitcher 34 is positioned at the front of the cutter 35 in its moving direction, with the cutting edge 353 moving between the two stitching flanges 343, thereby achieving stitching first and then cutting.

[0048] In one embodiment, Figure 8 As shown, the transverse movement device 33 includes an upper transverse movement belt 331, a lower transverse movement belt 332 and a transverse movement drive assembly 333. The upper transverse movement belt 331 and the lower transverse movement belt 332 are arranged in parallel, and the two transverse movement belts are arranged along a horizontal direction perpendicular to the cotton filling tube 22.

[0049] The upper transverse belt 331 is fixedly provided with an upper transverse plate 3311, and the upper mounting seat 31 is slidably provided on the upper transverse plate 3311, so that the upper mounting seat 31 can move toward or away from the lower mounting seat 32. Specifically, an upper lifting cylinder 3312 is provided on the upper transverse plate 3311, and the output end of the upper lifting cylinder 3312 is fixedly connected to the upper mounting seat 31. Through the action of the upper lifting cylinder 3312, the upper mounting seat 31 can slide in the vertical direction, thereby adjusting the distance between the upper mounting seat 31 and the lower mounting seat 32, and further adjusting the distance between the ultrasonic stitcher 341, the ultrasonic cutter 351 and the stitching wheel 342, the cutting wheel 352.

[0050] The lower transverse belt 332 is fixedly provided with a lower transverse plate 3321, and the lower mounting seat 32 is slidably provided on the lower transverse plate 3321. The lower mounting seat 32 moves toward or away from the upper mounting seat 31. Specifically, a lower lifting cylinder 3322 is provided on the lower transverse plate 3321, and the output end of the lower lifting cylinder 3322 is fixedly connected to the lower mounting seat 32. Through the action of the lower lifting cylinder 3322, the lower mounting seat 32 can slide in the vertical direction, so that the distance between the lower mounting seat 32 and the upper mounting seat 31 can be adjusted, and then the distance between the ultrasonic suturing device 341, the ultrasonic cutter 351 and the suturing wheel 342, the cutting wheel 352 can be adjusted. Specifically, there are two lower mounting seats 32, and correspondingly, there are also two lower lifting cylinders 3322. The suturing wheel 342 and the cutting wheel 352 are respectively arranged on the two lower mounting seats 32, so that the distance between the suturing wheel 342 and the cutting wheel 352 and the ultrasonic suturing device 341 and the ultrasonic cutter 351 can be independently adjusted.

[0051] The transverse drive assembly 333 includes a main drive rod 3331, a slave drive rod 3332, and a transverse motor 3333 that drives the main drive rod 3331. The ends of the upper and lower transverse belts 331 and 332 are connected to the main drive rod 3331 and the slave drive rod 3332, respectively. The main drive rod 3331 and the slave drive rod 3332 are disposed on either side of the filling tube 22. Upper and lower drive wheels are disposed at both ends of the main and slave drive rods 3331 and 3332. The ends of the upper transverse belt 331 are connected to the upper drive wheels on the main and slave drive rods 3331 and 3332, respectively. The ends of the lower transverse belt 332 are connected to the lower drive wheels on the main and slave drive rods 3331 and 3332, respectively. The transverse motor 3333 drives the main driving rod 3331 to rotate, and the main driving rod 3331 simultaneously drives the upper transverse belt 331 and the lower transverse belt 332 to move synchronously, thereby synchronously driving the upper transverse plate 3311 and the lower transverse plate 3321 to move horizontally, and then synchronously driving the upper mounting seat 31 and the lower mounting seat 32 to move horizontally.

[0052] In one embodiment, Figure 6 and Figure 7 As shown, in order to improve the stability of the sewing component 3 in cutting the pillowcase after filling with cotton, a cloth clamping component 4 is provided at the outlet of the cotton filling tube 22, so that the cloth can be cut more accurately and the edges of the cloth can be cut more neatly.

[0053] The cloth clamping assembly 4 includes a first transverse rod 41 and a second transverse rod 42 .

[0054] The first transverse movement cylinder 43 drives the first transverse movement rod 41 to move along the width direction of the cotton filling tube 22 .

[0055] A first upper clamping plate 411 and a first lower clamping plate 412 are slidably mounted on the first transverse rod 41. A first upper cylinder 413 is mounted on the first transverse rod 41, and the output end of the first upper cylinder 413 is connected to the first upper clamping plate 411. A first lower cylinder 414 is also mounted on the first transverse rod 41, and the output end of the first lower cylinder 414 is connected to the first lower clamping plate 412.

[0056] The second transverse cylinder 44 drives the second transverse rod 42 to move along the width direction of the cotton filling tube 22.

[0057] A second upper clamping plate 421 and a second lower clamping plate 422 are slidably mounted on the second transverse rod 42. A second upper cylinder 423 is mounted on the second transverse rod 42, and the output end of the second upper cylinder 423 is connected to the second upper clamping plate 421. A second lower cylinder 424 is also mounted on the second transverse rod 42, and the output end of the second lower cylinder 424 is connected to the second lower clamping plate 422.

[0058] By controlling the movement of the first transverse cylinder 43, the second transverse cylinder 44, the first upper cylinder 413, the first lower cylinder 414, the second upper cylinder 423, and the second lower cylinder 424, the first upper clamping plate 411, the first lower clamping plate 412, the second upper clamping plate 421, and the second lower clamping plate 422 can be clamped around the filling tube 22 during filling, tightly clamping the pillowcase to prevent cotton from leaking out during the filling process. When filling is completed, the filling tube 22 retracts, and at the same time, the first transverse cylinder 43 drives the first transverse rod 41 to move, thereby simultaneously moving the first upper clamping plate 411 and the second lower clamping plate 422, and the second transverse cylinder 44 drives the second transverse rod 42 to move, thereby simultaneously moving the second upper clamping plate 421 and the second lower clamping plate 422. The first upper clamping plate 411 and the second lower clamping plate 422 are clamped on one side of the pillowcase, and the second upper clamping plate 421 and the second lower clamping plate 422 are clamped on the other side of the pillowcase. When the first upper clamping plate 411, the second lower clamping plate 422 and the second upper clamping plate 421 and the second lower clamping plate 422 move away from each other, the pillowcase opening can be tightened and flattened, so that the opening of the pillowcase can be sewn more smoothly during the sewing process. In addition, by coordinating the rotation speed of the ultrasonic sewing device 341 and the ultrasonic cutter 351 driven by the first drive motor 311 and the second drive motor, the pillowcase opening can be sewn and cut more smoothly.

[0059] In addition, upper notches 415 are provided on both the first upper clamping plate 411 and the second clamping plate; lower notches 425 are provided on both the first lower clamping plate 412 and the second lower clamping plate 422. When the four clamping plates are assembled, the two upper notches 415 and the two lower notches 425 cooperate to form a filling hole 45, into which the filling tube 22 extends to fill the pillowcase. This ensures that during the filling process, all openings of the pillowcase are blocked to prevent leakage of cotton.

[0060] In one embodiment, Figure 9 As shown, to further improve the smoothness of the stitching at the pillowcase opening and increase the pillow core production rate, a first nip roller set 5 and a second nip roller set 6 are installed at the outlet of the filling tube 22. The cooperation of the first nip roller set 5 and the second nip roller set 6 can improve the production efficiency of the pillow core. Compared with the second nip roller set 6, the first nip roller set 5 is located closer to the sewing assembly 3.

[0061] The first nip roller assembly 5 includes a first lower nip roller 51 and a first upper nip roller 52, which can move toward each other. A first drive device 54 drives the first lower nip roller 51 or the first upper nip roller 52 to rotate. In this embodiment, first roller cylinders 55 are connected to both ends of the first upper nip roller 51. The two first roller cylinders 55 can simultaneously drive the first upper nip roller 52 to move vertically. The first drive device 54 is fixedly connected to the ends of the first lower nip roller 51. The first drive device 54 is a drive motor that can drive the first lower nip roller 51 to rotate via a belt.

[0062] The second nip roller assembly 6 includes a second lower nip roller 61 and a second upper nip roller 62 that can move toward each other. A second drive device 64 drives the second lower nip roller 61 or the second upper nip roller 62 to rotate. In this embodiment, a second roller cylinder 65 is connected to both ends of the second upper nip roller 62. Both second roller cylinders 65 can simultaneously drive the second upper nip roller 62 to move vertically. The second drive device 64 is fixedly connected to the end of the second lower nip roller 61. The second drive device 64 is a drive motor that can drive the second lower nip roller 61 to rotate via a belt.

[0063] The first clamping roller group 5 and the cloth clamping assembly 4 are respectively arranged on both sides of the tailoring assembly 3. The upper cloth 111 and the lower cloth 121 first pass through between the second upper clamping roller 62 and the second lower clamping roller 61, and then pass through between the first upper clamping roller 52 and the first lower clamping roller 51.

[0064] The first upper nip roller 52, the first lower nip roller 51, the second upper nip roller 62, and the second lower nip roller 61 maintain a clamped state between the upper and lower sides of the two layers of fabric. Specifically, the first roller cylinder 55 drives the first upper nip roller 52 downward, clamping the first upper nip roller 52 and the first lower nip roller 51 between the upper and lower sides of the two layers of fabric. The second roller cylinder 65 drives the second upper nip roller 62 downward, clamping the second upper nip roller 62 and the second lower nip roller 61 between the upper and lower sides of the two layers of fabric. The rotation of the first and second lower nip rollers 51 and 61 is controlled by the first and second drive devices 54 and 64, respectively.

[0065] When the pillowcase needs to be cut, the first roller cylinder 55 drives the first upper clamping roller 52 to move downward, so that the first upper clamping roller 52 and the first lower clamping roller 51 are clamped on the upper and lower sides of the two layers of cloth, thereby cooperating with the first upper clamping plate 411, the first lower clamping plate 412, the second upper clamping plate 421 and the second lower clamping plate 422 to clamp on both sides of the pillowcase, so that when the sewing component 3 sews and cuts the pillowcase, the edges of the pillowcase after sewing and cutting can be smoother.

[0066] In addition, the sewing assembly 13 is arranged on the side of the second nip roller group 6 away from the first nip roller group 5. In other words, the upper cloth 111 and the lower cloth 121 first pass through the sewing assembly 13 to sew their edges together, and then enter between the second upper nip roller 62 and the second lower nip roller 61, and then enter between the first upper nip roller 52 and the first lower nip roller 51.

[0067] Therefore, when the end pillowcase is being filled with cotton, sewn, or cut, the second lower clamping roller 61 can rotate independently and drive the pillowcase to move, so that the two sides of the pillowcase are sewn first, and the sewn pillowcase is stored between the first clamping roller group 5 and the second clamping roller group 6. After the sewing and cutting of the front pillowcase are completed, the first lower clamping roller 51 can rotate independently and quickly, so that the pillowcase stored between the first clamping roller group 5 and the second clamping roller group 6 is sent to the space between the first upper clamping plate 411, the first lower clamping plate 412, the second upper clamping plate 421, and the second lower clamping plate 422 for filling with cotton, sewing, and cutting, thereby improving the efficiency of pillow core production.

[0068] In one embodiment, Figure 9 As shown, in order to drive the first upper clamping roller 52 to rotate when the first lower clamping roller 51 rotates, a first meshing gear 53 is provided on the first lower clamping roller 51 and the first upper clamping roller 52. When the first lower clamping roller 51 and the first upper clamping roller 52 are clamped, the first meshing gears 53 on the first lower clamping roller 51 and the first upper clamping roller 52 are meshed and transmitted with each other, so that the pillowcase can be better conveyed.

[0069] Similarly, in order to drive the second upper clamping roller 62 to rotate when the second lower clamping roller 61 rotates, a second meshing gear 63 is provided on the second lower clamping roller 61 and the second upper clamping roller 62. When the second lower clamping roller 61 and the second upper clamping roller 62 are clamped, the second meshing gears 63 on the second lower clamping roller 61 and the second upper clamping roller 62 are meshed and transmitted with each other, so that the pillowcase can be better conveyed.

[0070] In one embodiment, the first upper clamping roller 52 and the first lower clamping roller 51 are both provided with a first annular groove 56; when the first upper clamping roller 52 and the first lower clamping roller 51 are clamped, the cotton filling tube 22 is located in the first annular groove 56 of the two clamping rollers; the first annular groove 56 does not affect the cotton filling tube 22 in filling the pillowcase without affecting the transmission of the pillowcase.

[0071] The second upper nip roller 62 and the second lower nip roller 61 are both provided with a second annular groove 66. When the second upper nip roller 62 and the second lower nip roller 61 are clamped, the cotton filling tube 22 is located in the second annular groove 66 of the two nip rollers. The second annular groove 66 does not affect the conveyance of the pillowcase and does not affect the filling tube 22 from filling the pillowcase with cotton.

[0072] In one embodiment, Figure 2 As shown, the sewing assembly 13 includes two ultrasonic side stitchers 131, one positioned on each side of the double-layer fabric. Side stitching wheels 132 are positioned at the bottom of the ultrasonic side stitchers 131. The double-layer fabric passes between the side stitching wheels 132 and the ultrasonic side stitchers 131, and the ultrasonic side stitchers 131 stitch the two sides of the fabric together. The side stitching wheels 132 are connected to the output end of a lower side motor 133 via a belt, which drives the side stitching wheels 132 to rotate. The ultrasonic side stitchers 131 are connected to the output end of an upper side motor 134 via a belt, which drives the side stitching wheels 132 to rotate. This ensures that when stitching the two layers of fabric, the ends of the ultrasonic side stitchers 131 are in even contact with the side stitching wheels 132, thereby extending the service life of the ultrasonic side stitchers 131. In addition, the side lower motor 133 and the side sewing wheel 132 are both arranged on the side panel, and a side slide plate 135 is slidingly arranged on the cotton filling frame 23. At the same time, a side cylinder 136 is arranged on the cotton filling frame 23. The output of the side cylinder 136 drives the side slide plate 135 to slide along the vertical direction, so that the distance between the side sewing wheel 132 and the ultrasonic side sewing device 131 can be adjusted to adapt to different sewing requirements.

[0073] The working principle of this application is as follows, which specifically includes the following steps: (1) An upper layer of cloth 111 is wound on the cloth roller, and a lower layer of cloth 121 is wound on the lower cloth roller 12. The upper layer of cloth 111 and the lower layer of cloth 121 overlap to form two layers of cloth, and the cotton filling tube 22 is located between the upper and lower layers of cloth. When the double-layer cloth passes through the sewing assembly 13, the sewing assembly 13 sews the sides of the upper layer of cloth 111 together, so that the double-layer cloth forms a sleeve-shaped pillowcase; the sewn pillowcase passes through the second upper clamping roller 62 and the second lower clamping roller 61, the first upper clamping roller 52 and the first lower clamping roller 51 in sequence, and under the action of the cotton filling tube 22 blowing air to the pillowcase, the pillowcase passes through the first upper clamping plate 411, the second upper clamping plate 421 and the first lower clamping plate 412, the second lower clamping plate 422.

[0074] (2) Driven by the cotton filling cylinder 25, the cotton filling tube 22 moves toward the first upper splint 411, the second upper splint 421 and the first lower splint 412, the second lower splint 422. After the end of the cotton filling tube 22 passes through the first upper splint 411, the second upper splint 421 and the first lower splint 412, the second lower splint 422, the first upper splint 411, the second upper splint 421, the first lower splint 412, the second lower splint 422 are clamped on the outside of the cotton filling tube 22, and the cotton filler 21 fills cotton into the pillowcase through the cotton filling tube 22.

[0075] (3) After the filling is completed, the filling tube 22 retracts under the drive of the filling cylinder 25; at the same time, the first transverse cylinder 43 drives the first transverse rod 41 to move, thereby simultaneously moving the first upper clamping plate 411 and the second lower clamping plate 422, and the second transverse cylinder 44 drives the second transverse rod 42 to move, thereby simultaneously driving the second upper clamping plate 421 and the second lower clamping plate 422 to move, and the first upper clamping plate 411, the second lower clamping plate 422 and the second upper clamping plate 421, the second lower clamping plate 422 move away from each other, thereby tightening and flattening the pillowcase opening.

[0076] (4) The upper transverse belt 331 and the lower transverse belt 332 synchronously drive the upper mounting seat 31 and the lower mounting seat 32 to move transversely. During the movement, the ultrasonic suturing device 341 and the suturing wheel 342 cooperate with each other to sew two side seams at the opening of the pillowcase. The ultrasonic cutting device 351 and the cutting wheel 352 cooperate to separate the pillowcase at the two seam edges. At this point, a pillow core is completed. Afterwards, the upper mounting seat 31 and the lower mounting seat 32 are reset. (5) The first upper clamping roller 52 and the first lower clamping roller 51 rotate, driving the cylindrical pillowcase to move toward the first upper clamping plate 411 and the first lower clamping plate 412; repeating the above steps (1) to (4) can achieve continuous production of pillow cores.

[0077] In the present application, an upper cloth 111 is wound around the upper cloth roller 11, and a lower cloth 121 is wound around the lower cloth roller 12. The upper cloth 111 and the lower cloth 121 overlap to form two layers of cloth, with a cotton filling tube 22 located between the two layers. Under the action of the sewing component 13, the two sides of the two layers of cloth are sewn together, forming a "sleeve shape" between the two layers of cloth. The cotton filling tube 22 then fills the sleeve-shaped cotton filling tube 22 with cotton to fill the pillow core. After the cotton filling is completed, the sewing component 3 sews two seams at the opening of the two layers of cloth, and then a cutter is used to cut between the two seams. One of the two seams serves as the seam edge of the newly made pillow core, and the other serves as the sealing seam edge at one end of the new pillowcase, preparing for the subsequent pillow core production. Therefore, the present application can simultaneously perform the pillow core production, pillowcase filling, and pillowcase sealing operations, achieving fully automated pillow core production.

[0078] In addition, in the above steps (3) and (4), that is, when the end pillowcase is being filled with cotton, sewn, and cut, the second lower clamping roller 61 can rotate independently and drive the pillowcase to move independently, so that the two sides of the pillowcase are sewn first, and the sewn pillowcase is stored between the first clamping roller group 5 and the second clamping roller group 6. After the sewing and cutting of the front pillowcase is completed, the first lower clamping roller 51 can rotate independently and quickly, so as to send the pillowcase stored between the first clamping roller group 5 and the second clamping roller group 6 to the first upper clamping plate 411, the first lower clamping plate 412, the second upper clamping plate 421, and the second lower clamping plate 422 for the next filling, sewing, and cutting, thereby improving the efficiency of pillow core production.
