Description

Technical Field

[0001] The present invention relates to the technical field of button fastening equipment, and in particular to an automatic button fastening machine and a button fastening method. Background Art

[0002] Integrated buttoning machines are widely used in packaging, medical, electronics and other fields to laminate diaphragms and substrates and fix them by buttoning. Traditional buttoning machines use mechanical structures to apply precise pressure to firmly install buttons on the corresponding materials. In this process, the membrane that supports the buttons is often difficult to maintain a stable state. Since traditional buttoning machines lack effective membrane fixing devices, when the stamping parts of the buttoning machines start to operate, the instantaneous impact force and the vibration of the machine itself will be transmitted to the diaphragm below, which will inevitably produce mechanical vibrations. These vibrations will be transmitted to the diaphragm, causing its position to shift or deform. The shaking of the diaphragm during the operation of the buttoning machine will cause uneven lamination, bubbles or wrinkles, affecting the lamination effect. Shaking may cause the adhesion between the diaphragm and the substrate to be loose, especially in the edge area, which is prone to peeling. Summary of the invention

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 7An automatic buttoning machine is proposed, wherein a first winding roller 2 is rotatably arranged on a frame 1; a first feeding roller 3 is rotatably arranged on the frame 1, and a first gap 7 is provided between the first winding roller 2 and the first feeding roller 3 for delivering a first material 23 coated with a film; a first pressing roller 4 is rotatably arranged and located on one side of the first gap 7; a second pressing roller 5 is rotatably arranged and located on one side of the first pressing roller 4, and a rotating shaft of the second pressing roller 5 is parallel to that of the first pressing roller 4, and a second gap 8 is provided between the first pressing roller 4 and the second pressing roller 5, and the first material 23 moves through the second gap 8, and the upper and lower end surfaces of the first pressing roller 4 and the second pressing roller 5 on one side of the width of the first material 23 are rolled and abutted.

[0023] In this embodiment, the first gap 7 is used to send the first material 23 coated with the film from the first feeding roller 3 to the subsequent processing unit, and the first pressing roller 4 and the second pressing roller 5 are used to roll and abut on both sides in the width direction, which effectively prevents the film from shaking or deflecting during transportation and improves the overall stability of the film. Since the film is well supported and fixed in the entire width direction, the frequent adjustments caused by the shaking of the film are reduced, and the operation efficiency of the production line is improved. By setting the first pressing roller 4 and the second pressing roller 5, the stability of the first material 23 is ensured during the buttoning process, the laminating effect is improved, the production efficiency is improved, and the reliability of the equipment is improved.

[0024] Further, the nip roller 6 is rotatably arranged, coaxial with the first nip roller 4, and located on one side of the axial direction of the first nip roller 4. The diameter of the nip roller 6 is smaller than the diameter of the first nip roller 4. When the first nip roller 4 rolls against the first material 23, a third gap 9 is formed between the nip roller 6 and the first material 23. The limiting member 10 is arranged on the nip roller 6, and is located at the end of the nip roller 6 away from the first nip roller 4. The distance from the end of the limiting member 10 close to the first material 23 to the upper end surface of the first material 23 is greater than the distance from the end of the nip roller 6 close to the first material 23 to the upper end surface of the first material 23. The limiting member 10 and the first nip roller 4 jointly block the left and right sides of the third gap 9. The nip roller 6 and the first nip roller 4 rotate in opposite directions. The fixed rod 11 is arranged inside the first pressing roller 4 and is coaxial with the first pressing roller 4. The first gear 12 is rotatably arranged on the fixed rod 11 and is arranged on the first pressing roller 4 and rotates synchronously with the first pressing roller 4. The rotating shaft of the second gear 13 is rotatably arranged on the fixed rod 11 and the second gear 13 is meshed with the first gear 12. The third gear 14 is rotatably arranged on the fixed rod 11 and is arranged on the pressing roller 6 and rotates synchronously with the pressing roller 6. The button sewing machine 16 is located on the side of the pressing roller 6 away from the first winding roller 2.

[0025] In this embodiment, the first material 23 itself is usually composed of a cloth layer with adhesiveness on one side and a plastic protective layer 22 attached to the adhesive surface. In the production process of the first material 23, there are the following processes depending on the product: The first process, such as Figure 1 , Figure 4 and Figure 5 As shown, before the first material 23 enters the first gap 7, a tool (not shown in the figure, its structure is described in detail later) is used to cut off the middle part of the plastic protective layer 22 of the first material 23, leaving the plastic protective layers 22 on both sides. Specifically, there are two tools, which are arranged at intervals on the same side of the first winding roller 2 and the first feeding roller 3 along the width direction of the first material 23, and can be swung to adjust the position. Through the position adjustment, the tool can cut the plastic protective layer 22 on the surface of the first material 23. The cut first material 23 passes through the second gap 8 to the workstation where the button sewing machine 16 is located. The purpose of leaving the plastic protective layers 22 on both sides is to better separate the rolled products after the buttoning, compounding and winding of the products are completed later.

[0026] Under this process condition, the first pressing roller 4 is above the first material 23, and the second pressing roller 5 is below the first material 23. The first pressing roller 4 and the second pressing roller 5 jointly press the plastic protective layer 22 on one side. Preferably, a group of first pressing rollers 4 and second pressing rollers 5 are arranged on both sides of the width direction of the first material 23. The first material 23 is supported by the pressing and fixing on the left and right sides, and the stability of the first material 23 during the buttoning process is improved. The blanking part 20 has a blanking part 2001, and the blanking part 2001 is an acute angle. The second material moves through the blanking part 2001; through the acute angle guidance, the circular product adhered to the plastic protective layer 22 and cut by the pressing ring 1805 of the pressing roller 1802 can be separated from the protective layer to which it adheres, so as to obtain the final product.

[0027] The second process, such as Figure 2 As shown, it is similar to the first process, except that the laminated product is directly rolled up at the end.

[0028] The third process, such as Figure 3 and Figure 6 As shown, it is suitable for products with high requirements for material stratification and separation. On the basis of the first material 23 (i.e., the plastic protective layer 22 is cut), before the first material 23 enters the buttoning machine, the anti-sticking layer 21 is bonded to the first material 23. Specifically, the width of the anti-sticking layer 21 is usually smaller than the width of the remaining plastic protective layers 22 on both sides, and its thickness is usually greater than the thickness of the remaining plastic protective layers 22 on both sides. And the bonding position is on the side of the two remaining plastic protective layers 22 close to the middle of the first material 23, and is adjacent to the plastic protective layers 22 on both sides respectively; During lamination, the anti-adhesive layer 21 is passed through the third gap 9. Preferably, the height of the third gap 9 should be equal to or slightly less than the thickness of the anti-adhesive layer 21 (slightly less than is considered in view of the elasticity of the cloth layer itself. If the elastic member 15 of the first material 23 itself is small, it is recommended that the height be equal to the thickness of the anti-adhesive layer 21 to prevent the first material 23 itself from being deformed due to pressure). The pressing roller 6 can perform lamination on the anti-adhesive layer 21. At the same time, the first pressing roller 4 and the second pressing roller 5 should be rolled on the remaining plastic protective layer 22. Preferably, the limiting member 10 is cylindrical and has a diameter greater than that of the pressing roller 6. Thus, the limiting member 10 can cooperate with the first pressing roller 4 to limit the left and right sides of the third gap 9, prevent the anti-adhesive layer 21 from shifting left and right, and improve the adhesion stability of the anti-adhesive layer 21. The pressing roller 6 is located on one side of the first pressing roller 4 and arranged adjacently, which has stronger stability.

[0029] Among them, as an implementation scheme, the first pressing roller 4 has no active driving source, that is, the first pressing roller 4 and the second pressing roller 5 only apply the upper and lower pressing force to the plastic protective layer 22, and rotate along with the movement of the first material 23, and drive the pressing roller 6 to rotate in the opposite direction through a series of transmission structures, which can reduce the slight sliding of the first material 23 caused by the same rotation direction in the traditional mode. At the same time, the reverse rotation of the pressing roller 6 can generate a reverse traction force, so that the anti-sticking layer 21 is slightly tightened. This helps to press the anti-sticking layer 21 and the fabric layer more tightly together, reduce bubbles and wrinkles, and improve the lamination quality.

[0030] The "series of transmission structures" refer to: a fixed rod 11, a first gear 12, a second gear 13 and a third gear 14, wherein the fixed rod 11 is preferably cylindrical, fixedly arranged, does not rotate with the first pressure roller 4, provides support for the first pressure roller 4 and the press roller 6, and provides a fixed position for the second gear 13, and the second gear 13 is rotated relative to the rotating rod, and the manner includes: the second gear 13 is provided with a rotating shaft, the rotating shaft extends to the fixed rod 11, and is rotatably arranged on the fixed rod 11, or the fixed rod 11 extends a normal branch, which is rotatably connected to the second gear 13 as an axis. Through a series of transmission structures, the press roller 6 and the first pressure roller 4 are rotated in the opposite direction.

[0031] One end of the fixed rod 11 is movably arranged on the frame 1; one end of the elastic member 15 is arranged on the frame 1, and the other end is arranged on the fixed rod 11, and is used to provide elastic force for the fixed rod 11 to move toward the second pressing roller 5. In this way, the first pressing roller 4 and the second pressing roller 5 can always keep pressing the first material 23, thereby improving adaptability.

[0032] In one example, the first pressing roller 4, the second pressing roller 5, the pressing roller 6 and the stopper 10 are stabilizing components 17. The stabilizing components 17 have four groups, which are arranged in pairs at the front and rear sections of the processing position where the button sewing machine 16 is located, and are respectively arranged on both sides of the width direction of the first material 23. By arranging the stabilizing components 17 at both ends of the button sewing machine 16, the cloth can be better supported stably to improve the overall stability.

[0033] Furthermore, the double-layer feeding assembly 18 includes: a winding roller 1801 for winding the second material; the corrugation roller 1802 and the winding roller 1801 are staggered in the height direction, and the outer peripheral surface of the corrugation roller 1802 has a plurality of corrugation rings 1805, and the corrugation rings 1805 are arranged at intervals along the circumference of the corrugation roller 1802; the transfer roller 1803 is located on one side of the corrugation roller 1802, and a fourth gap 1806 is provided between the corrugation roller 1802; the waste collection roller 1804 is staggered in the height direction with the corrugation roller 1802, and is located on both sides of the corrugation roller 1802 with the winding roller 1801.

[0034] In this embodiment, the double-layer feeding assembly 18 is mainly used to process the double-layer material and attach it to the first material 23. The double-layer material is usually composed of the second material and the plastic protective layer 22. Before attaching to the first material 23, the double-layer material passes through the fourth gap 1806. The second material is first cut into a circle by the pressing ring 1805 of the pressing roller 1802. After cutting, it is supplied and recovered in layers. The supplied part is the plastic protective layer 22 and the cut circular second material adhered to the plastic protective layer 22. The cut part of the second material is recovered by the waste collection roller 1804. The embossing roller 1802 and the coiling roller 1801 are arranged alternately in the height direction, and the waste collecting roller 1804 and the embossing roller 1802 are arranged alternately in the height direction, and are located on both sides of the embossing roller 1802 with the coiling roller 1801. This arrangement provides tension for the whole. According to different process requirements of different products, the double-layer feeding assembly 18 can be one or more groups.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
