Description

Technical Field

[0001] This utility model relates to the field of bag fabric processing technology, and in particular to a composite fabric bonding device for bag processing. Background Technology

[0002] Composite fabrics are a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials together. They mainly include functional fabrics such as cloth and cloth, cloth and paper, and cloth and artificial leather. They are suitable for making various bags, such as tote bags, suitcases and backpacks.

[0003] A search revealed that patent document CN211591680U discloses a composite fabric bonding device, including a housing, a first unwinding roller, a second unwinding roller, and a take-up roller. Supports are provided at the upper and lower ends of the left side of the housing. The first and second unwinding rollers are rotatably mounted on the supports at the upper and lower ends, respectively. Feed inlets are provided on the left side of the housing, below the first and above the second unwinding rollers. An electrostatic eliminator is located in the middle of the left inner wall of the housing, with discharge tips on both its upper and lower surfaces. An adhesive applicator is located on the right inner wall of the housing, near the electrostatic eliminator.

[0004] In the aforementioned prior art, although the dust collection box can suck up dust and the gap between the upper and lower pressure rollers can be quickly adjusted through the roller gap adjustment mechanism, it is not convenient to adjust the tightness of the fabric inside the box. When the two composite pressure rollers squeeze the two fabrics, the fabric is prone to wrinkling due to loosening, which will affect the quality of the composite extrusion of the fabric. Therefore, a composite fabric bonding device for bag processing is now proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of adjusting the tightness of fabrics and the tendency for fabrics to wrinkle due to loosening during extrusion, which affects the quality of fabric composite extrusion. Therefore, this invention proposes a composite fabric bonding device for bag processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A composite fabric bonding device for bag processing includes a box body, with a feed inlet symmetrically opened on one side of the box body and a discharge outlet opened on the other side of the box body. A support plate is provided on the outer wall of the box body, and a composite pressure roller and a pressing roller are symmetrically arranged inside the box body. Both ends of the composite pressure roller and the pressing roller are connected to a moving block through a rotating shaft.

[0008] The movable block is connected to the housing via an adjustment mechanism, which includes a servo motor, a first bidirectional screw, a second bidirectional screw, a first pulley, and a second pulley.

[0009] The output end of the servo motor is connected to the top of the first bidirectional screw, the first bidirectional screw is threadedly connected to the moving block, the first pulley is fixedly connected to the first bidirectional screw, the second pulley is fixedly connected to the second bidirectional screw, the second bidirectional screw is threadedly connected to the moving block, and the first pulley and the second pulley are connected by a belt.

[0010] Preferably, the outer wall of the box is symmetrically provided with guide wheels, the guide wheels are movably connected to a connecting plate through a connecting shaft, the connecting plate is fixedly connected to the box, and the edges of the inlet and the outlet are provided with rounded corners.

[0011] Preferably, a circular groove is provided on one side of the movable block, the rotating shaft is inserted into the circular groove, and the rotating shaft is fixedly connected to the composite pressure roller and the pressing roller.

[0012] Preferably, one side of the support plate has evenly distributed mounting grooves, and the interior of the mounting grooves is connected to the housing by a first bolt.

[0013] Preferably, the inner walls of the support plate and the box are symmetrically provided with limiting grooves, the inner walls of the limiting grooves are slidably connected to limiting blocks, and the limiting blocks are fixedly connected to the moving blocks.

[0014] Preferably, a first plate is fixedly connected to the top of the servo motor, a second plate is rotatably connected to the bottom of the first bidirectional screw, and a third plate is rotatably connected to both the top and bottom of the second bidirectional screw. The first plate, the second plate, and the third plate are all connected to the housing by second bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When using this equipment, the adjustment mechanism can control the two pressure rollers to move away from or closer to each other. When they are close to each other, the two bag fabrics can be kept taut, and the two bag fabrics are not easy to loosen. When the bag fabrics are squeezed by the composite pressure rollers, they are not easy to wrinkle, thus ensuring the quality of the composite extrusion of bag fabrics.

[0017] 2. When the composite pressure roller and the clamping roller need to be removed for maintenance or replacement, the support plate can be opened, and then the first bidirectional screw, the second bidirectional screw, the first pulley and the second pulley can be moved out of the inside of the housing. Then the moving block can be moved out of the rotating shafts at both ends of the composite pressure roller and the clamping roller, so that the composite pressure roller and the clamping roller can be removed separately, which is quite convenient.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 A composite fabric bonding device for bag processing includes a box body 1. A feed inlet 2 is symmetrically opened on one side of the box body 1, and a discharge outlet 3 is opened on the other side of the box body 1. A support plate 4 is provided on the outer wall of the box body 1. A composite pressure roller 5 and a pressing roller 6 are symmetrically arranged inside the box body 1. Both ends of the composite pressure roller 5 and the pressing roller 6 are connected to a moving block 7 through a rotating shaft.

[0026] It should be noted that the interior of the box 1 is equipped with an adhesive applicator, which is existing technology and is not shown. The adhesive applicator can apply adhesive to one of the bag fabrics, which facilitates the subsequent compression to press the two bag fabrics together. The specific structure and principle are described in detail in the patent document proposed in the background technology: A composite fabric bonding device (publication number: CN211591680U), and will not be described again.

[0027] The movable block 7 is connected to the housing 1 through an adjustment mechanism. The adjustment mechanism includes a servo motor 8, a first bidirectional screw 9, a second bidirectional screw 10, a first pulley 11, and a second pulley 12. It should be noted that the servo motor 8 controls the rotation of the first bidirectional screw 9, and the first bidirectional screw 9 controls the rotation of the second bidirectional screw 10 in the same direction through the first pulley 11, the belt 19, and the second pulley 12. The first bidirectional screw 9 and the second bidirectional screw 10 can rotate simultaneously.

[0028] The output end of the servo motor 8 is connected to the top of the first bidirectional screw 9. The first bidirectional screw 9 is threadedly connected to the moving block 7. The first pulley 11 is fixedly connected to the first bidirectional screw 9. The second pulley 12 is fixedly connected to the second bidirectional screw 10. The second bidirectional screw 10 is threadedly connected to the moving block 7. The first pulley 11 and the second pulley 12 are connected by a belt 19. It should be noted that when the first bidirectional screw 9 and the second bidirectional screw 10 rotate simultaneously, they control the two composite pressure rollers 5 or the two pressing rollers 6 to move closer or further apart from each other. When the composite pressure rollers 5 are adjusted, the tightness of the two bag fabrics can be controlled.

[0029] It should be noted that there are two servo motors (8 in total). The specific model and specifications to be used need to be selected based on the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described. Both of them can be powered and controlled to turn on and off by external devices.

[0030] Furthermore, guide wheels 13 are symmetrically arranged on the outer wall of the box body 1. The guide wheels 13 are movably connected to the connecting plate through the connecting shaft. The connecting plate is fixedly connected to the box body 1. The edges of the inlet 2 and the outlet 3 are rounded. It should be noted that the rounded corners are relatively smooth and can protect the bag fabric.

[0031] Furthermore, a circular groove is provided on one side of the movable block 7, and the rotating shaft is inserted into the circular groove. The rotating shaft is fixedly connected to the composite pressure roller 5 and the pressing roller 6. It should be noted that the setting of the rotating shaft and the circular groove makes it convenient to disassemble and remove the composite pressure roller 5 and the pressing roller 6 from the movable block 7.

[0032] Furthermore, a uniformly distributed mounting groove 14 is provided on one side of the support plate 4. The interior of the mounting groove 14 is connected to the housing 1 by a first bolt. It should be noted that a first hole is provided on the inner wall of the mounting groove 14, and a first threaded groove is provided on the inner wall of the housing 1. The first bolt passes through the first hole and is threadedly connected to the first threaded groove, so that the support plate 4 can be installed and fixed.

[0033] Furthermore, the inner walls of the support plate 4 and the box 1 are symmetrically provided with limiting grooves 15. The inner walls of the limiting grooves 15 are slidably connected to limiting blocks. The limiting blocks are fixedly connected to the moving blocks 7. It should be noted that by limiting the sliding of the limiting blocks and the limiting grooves 15, the two moving plates can make stable vertical linear movements.

[0034] Furthermore, the top of the servo motor 8 is fixedly connected to the first plate 16, the bottom of the first bidirectional screw 9 is rotatably connected to the second plate 17, and the top and bottom of the second bidirectional screw 10 are rotatably connected to the third plate 18. The first plate 16, the second plate 17, and the third plate 18 are all connected to the housing 1 by the second bolt. It should be noted that the first plate 16, the second plate 17, and the third plate 18 are all provided with second holes, and the inner wall of the housing 1 is provided with evenly distributed second threaded grooves. The second bolt passes through the second hole and is threadedly connected to the second threaded groove, which facilitates the removal of the servo motor 8, the first bidirectional screw 9, and the second bidirectional screw 10 from the inside of the housing 1.

[0035] Working principle of this utility model:

[0036] First, the two layers of bag fabric are passed through the two inlets 2, then through the two pressing rollers and the two composite pressure rollers 5, and then removed from the outlet 3, and the fabric is fixed on the corresponding winding equipment.

[0037] Then, the servo motor 8 controls the rotation of the first bidirectional screw 9. The first bidirectional screw 9 controls the rotation of the second bidirectional screw 10 in the same direction through the first pulley 11, the belt 19, and the second pulley 12. When the first bidirectional screw 9 and the second bidirectional screw 10 rotate, they can control the two composite pressure rollers 5 or the two pressing rollers 6 to move closer or further away from each other. When the composite pressure rollers 5 are adjusted, the tightness of the two bag fabrics can be controlled.

[0038] Finally, by controlling the two composite pressure rollers 5 to squeeze the two bag fabrics together, the two bag fabrics can be squeezed and bonded together.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
