Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric heat sealing, in particular to a degradable composite non-woven fabric heat sealing machine. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is made of directional or random fibers. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, antibacterial and degradable, and recyclable. When making non-woven fabric, short fibers or filaments are used to pass the fibers through air flow or mechanically into a net, and then they are reinforced by heat sealing.

[0003] For example, the Chinese patent with publication number CN117124690A, entitled "An Antibacterial, Degradable and Environmentally Friendly Composite Non-woven Fabric Heat Sealing Machine", comprises a bottom plate, one end of the top surface of the bottom plate is fixed with two support frames, the top and bottom of the support frames are both slidably connected with moving blocks, a connecting shaft is detachably and rotatably connected between the two moving blocks arranged relatively on the two support frames, a spinning roller is fixed on the outside of the connecting shaft, and the top and bottom ends of the support frames are both provided with a tensioning mechanism, the tensioning mechanism includes two positioning wheels 1, two positioning wheels 2 and a moving wheel. In the present invention, the top and bottom surfaces of the non-woven fabric are heated and pressurized simultaneously by two hot pressing plates, thereby improving the effect of hot pressing of the non-woven fabric. After the hot pressing is completed, the electric push rod 1 takes the hot pressing plate away from the non-woven fabric, and then the external air pump draws air into the exhaust pipe of the heat sealing box, so that the harmful gases in the hot pressing position space of the non-woven fabric are drawn away and collected from the exhaust pipe, thereby preventing the harmful gases from being absorbed by the staff.

[0004] Although the antibacterial, degradable and environmentally friendly composite non-woven fabric heat sealing machine in the above patent is practical and convenient, it also has its shortcomings. In the process of removing wrinkles from the non-woven fabric, the effect of eliminating wrinkles by straightening the non-woven fabric is not good. The non-woven fabric fiber structure is loose and has poor elasticity. It is difficult to completely smooth out deep wrinkles by simply straightening it. However, excessive straightening force may generate new stress in certain areas, resulting in new wrinkles or deformation, which still reduces the effect of subsequent gluing and heat sealing.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-10, an embodiment of the present invention provides a technical solution: the degradable composite non-woven fabric heat sealing machine includes a body 1, a transmission assembly and a locking assembly. A hot pressure head 2 is provided in the body 1, a connecting box 4 is horizontally reciprocatingly slidably connected in the body 1, a glue box 5 is provided in the connecting box 4, and a steam wrinkle remover 3 is movably connected in the body 1. When the number of horizontal back-and-forth movements of the steam wrinkle remover 3 reaches a preset value, the transmission assembly is used to rotate the steam wrinkle remover 3 90° toward the glue box 5 to a vertical state, and the locking assembly is driven by the horizontal movement of the steam wrinkle remover 3 in the vertical state to enable the steam wrinkle remover 3 to be engaged with the connecting box 4.

[0031] As a preferred technical solution, two rotating rods 31 are symmetrically connected to the body 1 for rotation. A transmission belt 32 is commonly connected to the two rotating rods 31. A slider 34 is vertically slidably sleeved on each of the two rotating rods 31. A second rack 29 and a third rack 30 are respectively provided on one side of the two sliders 34. The second rack 29 is located obliquely above the third rack 30. Two bearing blocks 26 are horizontally reciprocatingly slidably connected to the body 1. The first rotating shaft 27 is rotatably connected to the two bearing blocks 26. The steam wrinkle remover 3 is set on the first rotating shaft 27. One end of the first rotating shaft 27 close to the first rotating rod 31 is sleeved A second gear 28 is provided, and the second gear 28 is meshed with the second rack 29 and the third rack 30 in sequence. Specifically, two second guide rods 33 are symmetrically and vertically provided in the body 1, and two sliders 34 are vertically slidably sleeved with the two second guide rods 33 in a one-to-one correspondence. A sliding groove group is provided on the two rotating rods 31, and the two sliding groove groups include two spiral grooves connected end to end. A protrusion is provided in the two sliders 34, and the two protrusions are respectively slidably connected to the two sliding groove groups. The second guide rod 33 limits the axial rotation of the slider 34, so that the two sliders 34 can only reciprocate in the vertical direction.

[0032] As a preferred technical solution, the transmission assembly includes a ratchet 35, a first pawl 37 engaged with the ratchet 35, and a second pawl 40 engaged with the ratchet 35. The ratchet 35 is sleeved on a rotating rod 31 close to the second rack 29, and a connecting bracket 36 is provided on one side of a supporting block 26. The first pawl 37 and the second pawl 40 are both horizontally rotatably connected to the connecting bracket 36 by a reset member. Specifically, a cylinder is provided in the machine body 1 for pushing the connecting bracket 36 to move horizontally. When the steam wrinkle remover 3 moves toward the connecting box 4, the first pawl 37 and the second pawl 40 are not engaged with the ratchet 35. When the steam wrinkle remover 3 moves toward the direction of the principle connecting box 4, the first pawl 37 and the second pawl 40 are engaged with the ratchet 35 in turn, driving the two rotating rods 31 to rotate, the second rack 29 moves down, and the third rack 30 moves up. When the steam wrinkle remover 3 moves back and forth horizontally the number of times the steam wrinkle remover 3 moves back and forth reaches a preset value, wrinkle removal is completed at this time, and the slider 34 located above is aligned with the second rack The straight line distance in the vertical direction of the wheel 28 is less than the straight line distance in the vertical direction of the slider 34 located below and the second gear 28, so that the meshing time points of the second rack 29 and the third rack 30 with the second gear 28 are staggered. When the steam wrinkle remover 3 moves toward the connecting box 4, the second gear 28 first meshes with the second rack 29, causing the steam wrinkle remover 3 to rotate 90° toward the glue coating box 5 and to be in a vertical state. When the steam wrinkle remover 3 is engaged with the connecting box 4 and drives the glue coating box 5 to move horizontally in the opposite direction for glue coating, the first pawl 37 first meshes with the ratchet wheel 35. At this time, the second rack 29 moves upward under the drive of the slider 34, and the second gear 28 does not mesh with the second rack 29, avoiding the steam wrinkle remover 3 from reversing during the gluing process, causing motion interference, so that the steam wrinkle remover 3 remains in a vertical state to heat the glue during the gluing process of the glue coating box 5. At this time, the third rack 30 moves up to the meshing height under the drive of the corresponding slider 34, which is convenient for the subsequent resetting of the steam wrinkle remover 3.

[0033] As a preferred technical solution, both reset parts include a second rotating shaft 38, which is vertically arranged in the connecting bracket 36, and the first pawl 37 and the second pawl 40 are respectively rotatably sleeved on the two second rotating shafts 38. A torsion spring 39 is respectively provided between the first pawl 37 and the second pawl 40 and the two second rotating shafts 38. Specifically, through the elastic deformation of the torsion spring 39, when the steam wrinkle remover 3 moves toward the connecting box 4, the first pawl 37 and the second pawl 40 are not engaged with the ratchet 35, so that the rotating rod 31 does not rotate, and the meshing height of the second rack 29 is maintained, so that the second gear 28 can smoothly mesh with the second rack 29 for transmission, thereby realizing that the steam wrinkle remover 3 rotates 90° toward the glue coating box 5 and is in a vertical state.

[0034] As a preferred technical solution, the locking assembly includes a connecting block 8, a locking block 11, a connecting rod 14 and an arc head 15. The connecting block 8 is arranged on one side of the connecting box 4. The locking block 11 is vertically slidably connected to the connecting block 8 through an elastic assembly. A blind hole 9 is horizontally opened in the connecting block 8. The connecting rod 14 is vertically arranged on one side of the steam dewrinkle machine 3. The arc head 15 is fixedly connected to the bottom end of the connecting rod 14. When the steam dewrinkle machine 3 is in a vertical state, the arc head 15 is slidably connected in the blind hole 9, and the arc head 15 slides and abuts against the locking block 11. Specifically, the elastic assembly includes a first spring 12. A first slide groove 13 is vertically opened in the connecting block 8. The locking block 11 is slidably connected in the first slide groove 13. The first spring 12 is between the top wall of the first slide groove 13 and the locking block 11. The steam dewrinkle machine 3 When it moves in a vertical state toward the connecting box 4, the connecting rod 14 is in a horizontal state. When the arc head 15 slides along the blind hole 9, the locking block 11 moves upward under the extrusion of the arc head 15, and then the locking block 11 moves down through the elastic deformation of the first spring 12. At this time, the locking block 11 abuts against the arc head 15, and the steam wrinkle remover 3 moves in the opposite direction. The arc head 15 drives the locking block 11 to move, so that the steam wrinkle remover 3 drives the glue box 5 to move synchronously to glue the textile fabric that has been dewrinkled, and an opening 6 is provided on the side of the connecting box 4 close to the steam wrinkle remover 3. A plurality of nozzles 7 are provided at the bottom of the glue box 5. The steam of the steam wrinkle remover 3 is sent into the connecting box 4 through the opening 6, which can heat the glue in the glue box 5, thereby changing the physical properties of the glue to achieve a better gluing effect.

[0035] As a preferred technical solution, a contact block 16 is slidably sleeved on the connecting rod 14, and a second spring 17 is provided between the contact block 16 and the arc head 15. The second spring 17 is sleeved on the connecting rod 14, and a groove is provided at one end of the arc head 15 close to the contact block 16. The contact block 16 is engaged with the groove, and the end of the contact block 16 close to the arc head 15 is inclined. The contact block 16 slides and abuts against the locking block 11, and a second slide groove 24 is horizontally provided on the body 1. A first guide rod 23 is horizontally provided in the second slide groove 24. The connecting support plate 21 is horizontally slidably sleeved on the first guide rod 23. A third spring 22 is provided between one side of the connecting support plate 21 and the second slide groove 24. The third spring 22 is sleeved on the first guide rod 23. The body 1 There is a connecting support plate 21 connected to the inner horizontal sliding connection, and the connecting support plate 21 is rotatably connected to the first gear 19 through a cylinder 20. A first rack 25 meshing with the first gear 19 is horizontally set in the body 1, and a pushing block 18 is provided on the first gear 19. The pushing block 18 abuts against the end of the abutting block 16 away from the arc head 15. Specifically, in the process of the connecting rod 14 driving the abutting block 16 to move horizontally, when the pushing block 18 abuts against the end of the abutting block 16 away from the arc head 15, preferably, a guide groove 10 communicating with the blind hole 9 is horizontally opened on one side of the connecting block 8, and the pushing block 18 is slidably connected in the guide groove 10. The pushing block 18 pushes the abutting block 16 to move toward the arc head 15, and the locking block 11 is at the abutting block 16. The first gear 19 engages with the first rack 25, driving the push block 18 to rotate, and the second spring 17 drives the abutment block 16 to rotate. The steam de-wrinkle machine 3 moves in the opposite direction and is no longer engaged with the groove. The third spring 22 drives the connecting support plate 21 to move in the opposite direction and reset. The steam de-wrinkle machine 3 continues to move. At this time, the third rack 30 has moved to the meshing height. The second gear 28 meshes with the third rack 30, driving the steam de-wrinkle machine 3 to rotate in the opposite direction to a horizontal state. Then the steam de-wrinkle machine 3 continues to move. The second pawl 40 and the ratchet 35 rotate, and the third rack 30 moves down. During the reverse horizontal movement of the steam de-wrinkle machine 3, the second gear 28 does not mesh with the third rack 30, and the second rack 29 continues to move up and does not mesh with the second gear 28. When the steam de-wrinkle machine 3 moves horizontally toward the connecting box 4 in the horizontal state, one side of the steam de-wrinkle machine 3 pushes the connecting box 4 to move to the initial position, completing the reset.

[0036] Working principle: The degradable composite non-woven fabric heat sealing machine drives the steam wrinkle removal machine 3 to move back and forth by moving the connecting bracket 36 to remove wrinkles from the non-woven fabric multiple times, thereby improving the wrinkle removal effect and avoiding new deformation. In each process of moving away from the connecting box 4, the first pawl 37 and the second pawl 40 are engaged with the ratchet 35 in turn, the two rotating rods 31 rotate, the second rack 29 moves down, and the third rack 30 moves up. When the number of horizontal back and forth movements of the steam wrinkle removal machine 3 reaches a preset value, wrinkle removal is completed. When the steam wrinkle removal machine 3 is in a horizontal state and moves toward the connecting box 4, the second gear 28 first engages with the second rack 29, causing the steam wrinkle removal machine 3 to rotate 90° toward the glue coating box 5 to be in a vertical state, and steam wrinkle removal is completed. The machine 3 moves toward the connecting box 4 in a vertical state. When the arc head 15 slides along the blind hole 9, the locking block 11 moves upward under the pressure of the arc head 15, and then the locking block 11 moves down through the elastic deformation of the first spring 12. At this time, the locking block 11 abuts against the arc head 15, and the steam wrinkle remover 3 moves in the opposite direction. The arc head 15 drives the locking block 11 to move, so that the steam wrinkle remover 3 drives the glue coating box 5 to move synchronously. The first pawl 37 first engages with the ratchet 35. At this time, the second rack 29 moves upward under the drive of the slider 34, so that the steam wrinkle remover 3 maintains a vertical state to heat the glue during the gluing process of the glue coating box 5. At this time, the third rack 30 moves up to the meshing height driven by the corresponding slider 34, and then When the connecting rod 14 drives the abutment block 16 to move horizontally toward the third rack 30, when the pushing block 18 abuts against the end of the abutment block 16 away from the arc head 15, the pushing block 18 pushes the abutment block 16 to move toward the arc head 15, and the locking block 11 moves upward again under the pressure of the abutment block 16, and the abutment block 16 is engaged with the groove, and the connecting rod 14 continues to move. The locking block 11 passes through the end of the abutment block 16 away from the arc head 15 and the arc surface of the arc head 15 in turn, moves up and then down, the steam wrinkle remover 3 is unlocked from the connecting box 4, and the connecting rod 14 continues to move. The first gear 19 meshes with the first rack 25, driving the pushing block 18 to rotate, and the second spring 17 drives the abutment block 16 to move in the opposite direction and no longer engages with the groove The groove is engaged, and the third spring 22 drives the connecting support plate 21 to move in the opposite direction and reset. The steam wrinkle remover 3 continues to move. At this time, the third rack 30 has moved to the meshing height, and the second gear 28 is engaged with the third rack 30, driving the steam wrinkle remover 3 to rotate in the opposite direction to a horizontal state. Then the steam wrinkle remover 3 continues to move, the second pawl 40 and the ratchet 35 rotate, and the third rack 30 moves down, so that during the reverse horizontal movement of the steam wrinkle remover 3, the second gear 28 does not mesh with the third rack 30, and the second rack 29 continues to move up and does not mesh with the second gear 28. When the steam wrinkle remover 3 moves horizontally toward the connecting box 4 in the horizontal state, one side of the steam wrinkle remover 3 pushes the connecting box 4 to move to the initial position, completing the reset.
