Description

Technical Field

[0001] This application relates to the field of material lamination technology, and in particular to an automatic lamination machine. Background Technology

[0002] Currently, the production process of automotive parts requires the lamination and cutting of thin materials such as non-woven fabric and kraft paper with lightweight foam or materials such as glass fiber and wood fiber into specific material combinations, and then entering the hot pressing process to make prefabricated parts.

[0003] The existing composite cutting device manually places two layers of nonwoven fabric and foam material into a sandwich structure on a cutting machine. After the length is measured, the material is cut, and then the sandwich structure material is further processed.

[0004] The existing technical solutions mentioned above have the following drawbacks: during the feeding process, the two layers of non-woven fabric are dragged onto the cutting machine tool manually, which is inefficient. Utility Model Content

[0005] This application provides an automatic laminating machine to achieve automatic feeding and improve work efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] An automatic laminating machine includes a support frame placed horizontally along its length, a support plate placed horizontally at one end of the upper surface of the support frame, two first drive rollers rotatably disposed above the other end of the support frame, and two second drive rollers rotatably disposed above the support plate. The first drive rollers are connected to the support frame through a double-hole connecting plate, and the second drive rollers are connected to the support plate through the double-hole connecting plate and the connecting plate. The two first drive rollers are spaced apart, and the two second drive rollers are spaced apart. Each end face of the two first drive rollers and the two second drive rollers is provided with a connecting rod. The two first drive rollers and the two second drive rollers rotate together through gears meshing with each other on the peripheral wall of one side of the connecting rod. A cutting assembly is provided on the surface of the support plate.

[0008] By adopting the above technical solution, and by setting up a support frame, a support plate, a first drive roller, a second drive roller, and a cutting component, the first drive roller and the second drive roller can transport two layers of non-woven fabric. At the support plate, foam is placed between the two layers of non-woven fabric to form a sandwich structure. The sandwich structure is on the support plate. After the length is measured, it is cut by the cutting component, which facilitates further processing of the sandwich structure. The first drive roller and the second drive roller can realize the transport of non-woven fabric, which is more efficient than manually dragging the non-woven fabric to the cutting component.

[0009] Optionally, limiting components are fitted at both ends of the peripheral walls of the first and second drive rollers.

[0010] By adopting the above technical solution, the limiting component can prevent the upper and lower layers of nonwoven fabric from shifting during transport.

[0011] Optionally, two conveyor shafts are rotatably arranged between the first drive roller and the support plate. The conveyor shafts are connected to the support frame through connecting rods and support blocks coaxially arranged on the end faces, and a conveyor belt is sleeved on the peripheral wall of the conveyor shaft.

[0012] By adopting the above technical solution, the conveyor belt can transport non-woven fabric to the surface of the support plate, realizing automatic feeding.

[0013] Optionally, pulleys are fitted on the peripheral walls of a first drive roller, a second drive roller, and the connecting rod on the side of the transmission shaft away from the gear, and a synchronous belt is fitted on the peripheral walls of two adjacent pulleys.

[0014] By adopting the above technical solution, the first drive roller rotates, and the synchronous belt makes the conveyor shaft and the second drive roller rotate synchronously with the first drive roller. The synchronous belt can ensure that the conveying volume of the upper and lower layers of non-woven fabric and foam is the same and that no relative displacement occurs.

[0015] Optionally, a limiting plane is machined into the inner peripheral wall of the pulley, and the peripheral wall of the connecting rod is adapted to the inner peripheral wall of the pulley and the connecting rod is inserted into the inner peripheral wall of the pulley.

[0016] By adopting the above technical solution, the limiting plane can prevent the pulley from slipping while following the rotation of the first drive roller.

[0017] Optionally, the cutting assembly (2) includes a U-shaped cutting frame (22) disposed on the upper surface of the support plate (12), a cutting element (23) disposed between the support plate (12) and the cutting frame (22), and a cutting blade (25) vertically disposed on the cutting element (23) near the surface of the support plate (12). The cutting element (23) can drive the cutting blade (25) to reciprocate in a direction perpendicular to the surface of the support plate (12).

[0018] By adopting the above technical solution, and by setting up a cutting frame, a cutting component, and a cutting blade, the cutting component drives the cutting blade to reciprocate along the direction of the vertical support plate, which can cut the sandwich structure with the measured length, facilitating subsequent processing.

[0019] Optionally, limiting slides are provided on both ends of the cutting piece, and limiting grooves are provided on the inner walls of the cutting frame. The limiting slides are adapted to the limiting grooves and are slidably disposed in the limiting grooves.

[0020] By adopting the above technical solutions, the limiting slide and the limiting slide can prevent the cutting part from shaking during the movement and reducing the cutting effect.

[0021] Optionally, the support plate has a corresponding cavity on the upper surface that can accommodate the cutting blade.

[0022] By adopting the above technical solution, the receiving cavity can prevent the cutting blade from contacting the support plate surface after cutting the sandwich structure, thus avoiding damage to the cutting blade.

[0023] Optionally, the cutting assembly also includes a parallel roller disposed on the support plate between the second drive roller and the fixed frame. Limiting rings are sleeved at both ends of the parallel roller's peripheral wall. The parallel roller is rotatably disposed above the support plate via a connecting plate.

[0024] By adopting the above technical solutions, the parallel rollers and limiting rings can prevent the sandwich structure of two layers of nonwoven fabric and foam from shifting during the conveying process, thus reducing the yield rate.

[0025] In summary, this application has the following technical effects:

[0026] 1. By setting up a support frame, a support plate, a first drive roller, a second drive roller, and a cutting assembly, the first and second drive rollers can transport two layers of non-woven fabric. At the support plate, foam is placed between the two layers of non-woven fabric to form a sandwich structure. The sandwich structure is on the support plate. After the length is measured, it is cut by the cutting assembly to facilitate further processing of the sandwich structure. The first and second drive rollers can realize the transport of non-woven fabric, which is more efficient than manually dragging the non-woven fabric to the cutting assembly.

[0027] 2. By setting a synchronous belt, the first drive roller rotates, and the synchronous belt makes the conveyor shaft and the second drive roller rotate synchronously with the first drive roller. The synchronous belt can ensure that the upper and lower layers of non-woven fabric and foam are conveyed at the same rate and do not produce relative displacement.

[0028] 3. By setting up a cutting frame, cutting parts and cutting blades, the cutting parts drive the cutting blades to reciprocate along the direction of the vertical support plate, which can cut the sandwich structure with the measured length, making subsequent processing convenient.

Gears are provided on the peripheral walls of the connecting rods of the upper and lower first drive rollers 16. The gears mesh with each other. The motor drives the lower first drive roller 16 to rotate, and the gears cause the upper first drive roller 16 to rotate, thus moving the non-woven fabric placed on the lower placement frame 112 onto the conveyor belt 141. The conveyor belt 141 transports the non-woven fabric to the upper surface of the support plate 12.

[0041] Combination Figure 1 and Figure 2 The double-hole connecting plate 15 is provided with an upper placement frame 113 on the side away from the conveyor belt 141. The upper placement frame 113 is a U-shaped frame composed of two parallel and spaced square columns and a rotating rod rotatably set between the two square columns.

The second drive rollers 17 are cylindrical, and each end of the peripheral wall of the second drive roller 17 is fitted with a limiting member 18. A connecting rod is coaxially arranged on both ends of the second drive roller 17. The connecting rod is rotatably arranged in the through hole of the double-hole connecting plate 15, and the end of the connecting rod away from the second drive roller 17 is located outside the connecting plate. The axes of the two second drive rollers 17 are parallel to each other and spaced apart. The two second drive rollers 17 are arranged one above the other between the double-hole connecting plates 15.

The end of the connecting rod's peripheral wall is adapted to the inner wall of the pulley 19, and the pulley 19 is fitted onto the end of the connecting rod. Two synchronous belts 191 are respectively fitted onto the outer peripheral walls of two adjacent pulleys 19. The motor drives the two first drive rollers 16 to rotate, and the synchronous belts 191 cause the transmission shaft 14 and the second drive roller 17 to rotate synchronously with the first drive rollers 16. The synchronous belts 191 ensure that the conveying volume of the upper and lower layers of nonwoven fabric and foam is the same, preventing relative displacement.

[0045] Combination Figure 1 and Figure 2 During the operation, the non-woven fabric rolls are placed on the lower placement rack 112 and the upper placement rack 113 respectively. The upper and lower layers of non-woven fabric are conveyed by the first drive roller 16 and the second drive roller 17 to the cutting component 2 for cutting. During the conveying process, the lower layer of non-woven fabric can move the foam located above the conveyor belt 141 due to its certain adhesiveness, forming a sandwich structure at the support plate 12.

[0048] Combination Figure 1 and Figure 2 The upper surface of the support plate 12 has a corresponding cavity 121 for accommodating the blade of the cutting blade 25. The cavity 121 is strip-shaped and prevents the cutting blade 25 from contacting the support plate surface after cutting the sandwich structure, thus avoiding damage to the blade. The cutting assembly 2 also includes a parallel roller 21 disposed on the upper surface of the support plate 12 between the second drive roller 17 and the fixed frame 26. The parallel roller 21 is cylindrical, and limiting rings are fitted at both ends of its peripheral wall. The parallel roller 21 is rotatably disposed above the support plate 12 via a connecting plate. The parallel roller 21 and the limiting rings prevent the two layers of nonwoven fabric and foam from shifting during the conveying process, thus reducing the yield rate.
