Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a multi-station cutting, folding and welding equipment. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is made of polyester fiber and polypropylene fiber. It is composed of oriented or random fibers. It is called cloth because it has the appearance and some properties of cloth. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive and recyclable.

[0003] Currently, nonwoven fabrics are produced in rolls of a certain width. In subsequent applications, the nonwoven fabric needs to be slit to a predetermined width. For example, in the production of airbag protective covers, the width of the nonwoven fabric at the factory is much larger than the width required for the finished product. Therefore, the nonwoven fabric needs to be cut to meet the width requirements. Conventional cutting processes involve cutting on a single roller and then collecting the cut products. However, in processes requiring double-layer nonwoven fabric, a double-layer feeding device with positioning function is needed to simultaneously feed and fold the double-layer nonwoven fabric before welding and edge trimming. This requires multiple pieces of equipment, resulting in numerous machines, large floor space, high production costs, and low production efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a multi-station cutting, folding and welding equipment to solve the above-mentioned technical problems.

[0005] A multi-station cutting, folding, and welding device includes a main body, a cutting assembly mounted on the main body, a folding assembly positioned along the material flow direction of the cutting assembly, a welding assembly positioned along the material flow direction of the folding assembly, and a trimming assembly positioned along the material flow direction of the welding assembly. The main body includes a frame and a material flow channel mounted on the frame. The material flow channel utilizes multiple parallel rollers. The cutting assembly includes a second roller. The folding assembly includes a paper-pressing block positioned along the material flow direction of the cutting assembly and a folding block positioned on one side of the paper-pressing block. The paper-pressing block includes a paper-feeding end located near one end of the second roller, a paper-exiting end located at the other end, and a paper-pressing side positioned along the long side of the paper-pressing block. The paper-feeding end and the paper-exiting end are both spaced apart from a feeding roller in the material flow channel. The extending direction of the paper-pressing side is consistent with the product transport direction. The folding block includes a folding feed end located near one end of the second roller, a folding output end located at the other end of the folding block, and a folding side disposed along the long side of the folding block. The folding block has a trapezoidal structure, with the folding feed end as the upper base, the folding output end as the lower base, and the folding side as a sloping edge. The distance from the folding block to the material flow channel is greater than the distance from the pressure block to the material flow channel. The folding feed end is located on one side of the pressure feed end and is spaced apart in a horizontal direction perpendicular to product transport. The width of the folding output end is the sum of the width of the folding feed end and the width of the pressure output end, and the folding output end is located above the pressure output end away from the material flow channel. The folding output end coincides with the pressure output end. The welding assembly includes a fourth roller. The edge trimming assembly includes an edge trimming roller disposed in the material flow direction of the fourth roller and a fifth roller disposed in the material flow direction of the edge trimming roller.

[0006] Furthermore, the main body of the equipment also includes a feeding end located at one end of the logistics channel and a discharging end located at the other end of the logistics channel, wherein the feeding end and the discharging end are respectively located at both ends of the logistics channel in the logistics direction.

[0007] Furthermore, the cutting assembly includes a first roller disposed on the logistics channel, a cutting roller disposed in the logistics direction of the first roller, and a second roller disposed in the logistics direction of the cutting roller.

[0008] Furthermore, the cutting roller includes an upper roller and a lower roller, and at least one cutting head is provided in the center of the upper roller. The cutting edge of the cutting head faces the radial direction of the upper roller. The lower roller of the cutting roller is also provided with a clearance groove corresponding to the position of the cutting head.

[0009] Furthermore, the position of the paper pressing side is consistent with the position of the cutting edge of the cutting roller.

[0010] Furthermore, the welding assembly includes a third roller disposed in the material flow direction of the folding assembly, two ultrasonic welding devices disposed in the material flow direction of the third roller, and a fourth roller disposed in the material flow direction of the ultrasonic welding devices.

[0011] Furthermore, the third and fourth rollers are two leveling processes respectively set on both sides of the cutting roller. Both processes use two pressure rollers, one above the other, to pass the product through the middle of the two pressure rollers.

[0012] Furthermore, the cutting roller includes an upper roller and a lower roller. The upper roller has a ring of patterned protrusions with right-angled edges, and the lower roller has a corresponding clearance groove.

[0013] Compared with existing technologies, the multi-station cutting, folding, and welding equipment provided by this utility model cuts the product in half by setting the cutting rollers, and sets two sets of roller structures before and after the cutting rollers to ensure the flatness of the product surface. By setting the folding component, the product cut in half is folded, and one half is folded onto the other half by the guiding action of the folding block, so that the two overlap to form a double-layer structure. The structure is simple, the operation is convenient, and it can quickly produce double-layer non-woven fabric products. By setting the main body of the equipment, multiple processes such as cutting, flattening, folding, welding, and edge trimming are integrated into one machine, realizing multi-process integration, facilitating the production line operation, effectively reducing equipment costs, reducing the equipment footprint, and helping to increase production capacity.

[0019] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0020] like Figures 1 to 5 The diagram shown is a structural schematic of the multi-station cutting, folding, and welding equipment provided by this utility model. The multi-station cutting, folding, and welding equipment includes a main body 10, a cutting component 20 disposed on the main body 10, a folding component 30 disposed in the material flow direction of the cutting component 20, a welding component 40 disposed in the material flow direction of the folding component 30, and an edge-cutting component 50 disposed in the material flow direction of the welding component 40. It is conceivable that the multi-station cutting, folding, and welding equipment also includes other functional modules such as material driving equipment, electrical control equipment, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0021] The main body of the equipment 10 includes a frame 11, a logistics channel 12 disposed on the frame 11, a loading end 13 disposed at one end of the logistics channel 12, and a unloading end 14 disposed at the other end of the logistics channel 12.

[0022] The frame 11 can be a stainless steel housing used to support and carry the logistics channel 12. In addition, the frame 11 is also equipped with a number of other components, including but not limited to drive devices that drive the movement of the logistics channel 12, electrical boxes that provide electrical control, etc., which are all common technologies used in the field of mechanical equipment, and therefore will not be described in detail here.

[0023] The logistics channel 12 is a transmission component mounted on the frame 11, which can be a conveyor belt or rollers for transporting products. In the embodiments of this application, multiple parallel rollers are used to move the products in one direction, passing through each workstation.

[0024] The loading end 13 and unloading end 14 are respectively located at both ends of the logistics direction of the logistics channel 12. They can be two collection mechanisms with roll-up equipment to facilitate loading and unloading of products. This should be a common technology in the field of nonwoven fabric production, and is not the main content of this application. Therefore, it is only briefly described here.

[0025] The cutting assembly 20 includes a first roller 21 disposed on the logistics channel 12, a cutting roller 22 disposed in the logistics direction of the first roller 21, and a second roller 23 disposed in the logistics direction of the cutting roller 22.

[0026] The first roller 21 and the second roller 23 are two leveling processes respectively arranged on both sides of the cutting roller 22. Both processes achieve the flatness of the product surface by setting two pressure rollers, one above the other, so that the product passes through the middle of the two pressure rollers. This should be a common technology in the production of products such as steel plates, flooring and non-woven fabrics. For example, it is described in detail in the Chinese invention CN202510201146.0, which discloses a steel plate leveling device and its usage method. However, it is not the main content of this application, so it is only briefly described here.

[0027] The cutting roller 22 includes an upper roller and a lower roller, and at least one cutting blade is disposed in the center of the upper roller. The cutting edge of the cutting blade faces radially toward the upper roller, so that when the product passes between the upper and lower rollers, it is cut into two parts from the center. Accordingly, the lower roller of the cutting roller 22 should also be provided with a clearance groove corresponding to the position of the cutting blade, so as to avoid interference between the cutting blade and the lower roller when the upper roller rotates, thus preventing damage to the cutting edge.

[0028] The folding assembly 30 includes a paper pressing block 31 disposed in the logistics direction of the cutting assembly 20, and a folding block 32 disposed on one side of the paper pressing block 31.

[0029] The pressure block 31 can be a rectangular plate, including a pressure feed end 311 located near one end of the second roller 23, a pressure output end 312 located at the other end, and a pressure side 313 arranged along the long side of the pressure block 31. The pressure feed end 311 and the pressure output end 312 are both spaced apart from a paper feed roller of the logistics channel 12, so that the product can be conveyed from below the pressure block 31. The extension direction of the pressure side 313 is consistent with the conveying direction of the product, and the position of the pressure side 313 is consistent with the position of the blade of the cutting roller 22, so that when the product is conveyed from below the pressure block 31, the gap in the product cut by the cutting roller 22 is aligned with the pressure side 313, that is, one half of the product cut in half by the cutting roller 22 is located directly below the pressure block 31 from the cut seam.

[0030] The folding block 32 includes a folding feed end 321 located near one end of the second roller 23, a folding output end 322 located at the other end of the folding block 32, and a folding side 323 arranged along the long side of the folding block 32. The folding block 32 has a trapezoidal structure, with the folding feed end 321 as the upper base, the folding output end 322 as the lower base, and the folding side 323 as the inclined side. The distance from the folding block 32 to the material flow channel 12 is greater than the distance from the pressure block 31 to the material flow channel 12, so that the other half of the product cut by the cutting roller 22 can pass between the folding block 32 and the pressure block 31. The folding feed end 321 is located on one side of the pressure feed end 311 and is spaced apart in a horizontal direction perpendicular to the product transport. The width of the folded paper output end 322 is the sum of the width of the folded paper input end 321 and the width of the paper pressing output end 312, and the folded paper output end 322 is located above the paper pressing output end 312 away from the logistics channel 12, that is, the folded paper output end 322 coincides with the paper pressing output end 312.

[0031] It is conceivable that when the product cut in the middle by the cutting roller 22 moves to the folding assembly 30, one half of the product is pressed down by the pressure block 31 and moves between the pressure block 31 and the feeding roller of the logistics channel 12. The other half of the product is located between the pressure block 31 and the folding block 32, and under the guidance of the folding block 32, it gradually overlaps the pressure block 31 from the folding inlet end 321 to the folding outlet end 322, along the folding side 323. When the product exits from the folding outlet end 322 and the pressure outlet end 312, the two halves of the product overlap. Accordingly, a feeding roller can be provided at the outlet end to transport the overlapping double-layer product.

[0032] The welding assembly 40 includes a third roller 41 disposed in the material flow direction of the folding assembly 30, two ultrasonic welding devices 42 disposed in the material flow direction of the third roller 41, and a fourth roller 43 disposed in the material flow direction of the ultrasonic welding devices 42.

[0033] The third roller 41 and the fourth roller 43 are two leveling processes respectively set on both sides of the cutting roller 22. Both are set with two pressure rollers, one above the other, to pass the product through the middle of the two pressure rollers. They have the same structure and function as the first roller 21 and the second roller 23, so only a brief description is given here.

[0034] The ultrasonic welding device 42 is an industrial welding machine used to weld overlapping products. The principle is that a generator produces a 20kHz (or 15kHz) high-voltage, high-frequency signal, which is converted into high-frequency mechanical vibration by a transducer system. This vibration is applied to the plastic workpiece, and the temperature at the interface rises due to friction between the workpiece surface and molecules. When the temperature reaches the melting point of the workpiece, the interface melts rapidly, filling the gaps between the joints. When the vibration stops, the workpiece cools and solidifies under pressure, achieving the welding purpose. Two ultrasonic welding devices 42 are arranged side-by-side in the material flow direction to weld the two sides of the overlapping products respectively.

[0035] The edge trimming assembly 50 includes an edge trimming roller 51 disposed in the material flow direction of the fourth roller 43, and a fifth roller 52 disposed in the material flow direction of the edge trimming roller 51.

[0036] The trimming roller 51 includes an upper roller and a lower roller. A patterned protrusion is provided on the upper roller, and the edge of the protrusion is right angled. A corresponding clearance groove is provided on the lower roller. When the product passes between the two rollers, it will be cut by the edge of the protrusion under the pressure of the protrusion, thereby forming a lace.

[0037] The fifth roller 52 is located between the cutting roller 51 and the unloading end 14. It is the last leveling process before unloading. It has the same structure and function as the first roller 21 and the second roller 23, so it is only briefly described here.

[0038] Compared with existing technologies, the multi-station cutting, folding, and welding equipment provided by this utility model cuts the product in half by setting the cutting roller 22. Two sets of roller structures are set before and after the cutting roller 22 to ensure the flatness of the product surface. By setting the folding component 30, the cut product is folded in half, with one half guided by the folding block 32 to fold onto the other half, causing them to overlap and form a double-layer structure. The structure is simple, the operation is convenient, and it can quickly produce double-layer non-woven fabric products. By setting the main body 10, multiple processes such as cutting, flattening, folding, welding, and edge trimming are integrated into one machine, realizing multi-process integration, facilitating streamlined production, effectively reducing equipment costs, minimizing equipment footprint, and helping to increase production capacity.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
