Description

Technical Field

[0001] The present application relates to the technical field of composite bag processing, and in particular to a composite bag trimming and deviation correction device. Background Art

[0002] Plastic refers to a material that is made of resin (or directly polymerized with monomers during processing) as the main component, and additives such as plasticizers, fillers, lubricants, and colorants as auxiliary components. It can flow and form during processing. It is a synthetic polymer compound that can change its shape freely. It is a material that is polymerized by synthesis or condensation reaction using monomer raw materials. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Its main component is synthetic resin. Composite plastic packaging bags are made of synthetic resin or natural resin as the basic raw material, with (or without) various plastic additives, reinforcing materials, and fillers. They are processed and molded or cross-linked and cured at a certain temperature and pressure to obtain solid materials or products. Plastic composite bags need to be trimmed during production to remove excess edge materials of the product and enhance product quality.

[0003] A Chinese patent with application number 202123349561.7 discloses a composite film trimming and traction device, including an operating table, on the top surface of which three sets of bracket plates are fixedly installed; the composite film of the utility model can use two trimming blades to cut off the edge materials on both sides of the composite film during horizontal movement, so that the two sides of the composite film are smoother, and the sliding seat can slide in the guide groove so that the distance between the two trimming blades can be adjusted, which is convenient for the trimming device to trim composite films with different requirements.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application discloses a composite bag trimming and deviation correction device, such as Figure 1 and Figure 2 As shown, it includes a frame 1 and two conveying rollers 11 arranged on the frame 1, and the composite bag bypasses the upper ends of the two conveying rollers 11. A correction component 2 for correcting the composite bag is arranged between the two conveying rollers 11, and the correction component 2 includes a fixed plate 21 for supporting the composite bag, a mounting plate 22 arranged just above the fixed plate 21, two moving parts 23 and two correction parts 24 for limiting the composite bag. The fixed plate 21 is fixedly arranged on the upper end surface of the frame 1, and the upper end surface of the fixed plate 21 is a horizontal plane. The composite bag bypasses the upper end surface of the fixed plate 21. The mounting plate 22 is arranged on the frame 1, and a gap is left between the mounting plate 22 and the fixing plate 21 for the composite bag to pass through. Cylinders 12 are arranged on both sides of the mounting plate 22 along the moving direction of the composite bag, and the cylinder body of the cylinder 12 is fixedly installed on the frame 1, and the telescopic rod of the cylinder 12 is fixedly connected to the lower end surface of the mounting plate 22. The installation plate 22 is driven to move up and down by the extension and contraction of the two cylinders 12 to move closer to or farther away from the composite bag.

[0034] like Figure 3As shown, a cleaning portion 3 is provided on the lower end surface of the mounting plate 22, and a first screw 32 is provided on the upper end surface of the cleaning portion 3. The upper end of the first screw 32 passes through the mounting plate 22, and a nut 33 for fixing the cleaning portion 3 and the mounting plate 22 is provided on the upper end of the first screw 32. The nut 33 is threadedly connected to the first screw 32. Through the mutual cooperation between the nut 33 and the first screw 32, the upper end surface of the cleaning portion 3 is tightly abutted against the lower end surface of the mounting plate 22. A soft brush 31 for cleaning the upper end surface of the composite bag is provided on the lower end surface of the cleaning portion 3. The soft brush 31 is driven downward by the cylinder 12 to abut against the upper end surface of the composite bag, so that the upper end surface of the composite bag is cleaned during the movement of the composite bag.

[0035] like Figure 2 and Figure 3 As shown, a through groove 221 perpendicular to the moving direction of the composite bag is provided on the upper end surface of the mounting plate 22, and there is no overlapping part between the through groove 221 and the cleaning part 3 in the vertical direction. The through groove 221 passes through the upper and lower sides of the mounting plate 22, and the moving part 23 is slidably arranged in the through groove 221, and the lower end surface of the moving part 23 abuts against the upper end surface of the mounting plate 22, and the moving part 23 fits against the inner wall of the through groove 221. A bidirectional screw rod 222 is provided in the through slot 221 for driving the two moving parts 23 to slide in mirror image. Both ends of the bidirectional screw rod 222 are rotatably connected to the inner wall of the through slot 221. One end of the bidirectional screw rod 222 passes through the mounting plate 22. A first motor 223 for driving the bidirectional screw rod 222 to rotate is fixedly provided on the side wall of the mounting plate 22. The first motor 223 is fixedly installed on the side wall of the mounting plate 22 and moves up and down with the mounting plate 22. The output shaft of the first motor 223 is coaxially fixedly connected to one end of the bidirectional screw rod 222 passing through the mounting plate 22. The bidirectional screw rod 222 is driven to rotate by the rotation of the first motor 223. The two moving parts 23 are respectively threadedly connected to the bidirectional screw rod 222. The thread rotation directions of the bidirectional screw rod 222 connected to the two moving parts 23 are opposite. The rotation of the bidirectional screw rod 222 drives the two moving parts 23 to move in mirror image. Thus, the spacing between the two moving parts 23 is adjusted.

[0036] like Figure 3 As shown, the deviation-correcting part 24 is fixedly arranged at the lower end of the moving part 23, and the deviation-correcting part 24 is arranged in the gap between the fixing plate 21 and the mounting plate 22. The lower end surface of the deviation-correcting part 24 is a horizontal surface. During the movement of the composite bag, the mounting plate 22 is driven downward by the cylinder 12, so that the lower end surface of the deviation-correcting part 24 abuts against the upper end surface of the fixing plate 21. The side of the deviation-correcting part 24 close to each other is an arc surface, and the arc surface is close to both sides of the composite bag to prevent the composite bag from lateral displacement.

[0037] like Figure 2As shown, a slider 4 is provided on the upper end surface of the moving part 23, and the slider 4 is slidably provided on the upper end surface of the moving part 23 along a direction parallel to the moving direction of the moving part 23. A second screw 231 is provided on the upper end surface of the moving part 23 for driving the slider 4 to move. Both ends of the second screw 231 are rotatably connected to the moving part 23, and a screwing handle 232 is provided at one end of the second screw 231 away from each other. The second screw 231 is threadedly connected to the slider 4, and the position of the slider 4 is adjusted by rotating the second screw 231. The slider 4 is provided with a trimming tool 5 for trimming the composite bag. The trimming tool 5 is rotatably connected to the slider 4. The rotation axis of the trimming tool 5 is parallel to the sliding direction of the slider 4. The slider 4 is provided with a bolt 41 for limiting the trimming tool 5. The bolt 41 is threadedly connected to the side wall of the slider 4. The rotation axis of the bolt 41 is parallel to the rotation axis of the trimming tool 5. One end of the bolt 41 passes through the slider 4 and abuts against the trimming tool 5. By tightening the bolt 41, the trimming tool 5 is fixed. The end of the trimming tool 5 away from the slider 4 is located on the side of the mounting plate 22 along the moving direction of the composite bag. The frame 1 is provided with a rotating roller 6 that cooperates with the trimming tool 5. The rotating roller 6 is rotatably arranged on the upper end surface of the frame 1. The rotating roller 6 is arranged on the side of the mounting plate 22 along the conveying direction of the composite bag. The upper end of the rotating roller 6 is in the same horizontal plane as the upper end surface of the fixing plate 21. One end of the trimming tool 5 away from the slider 4 is downwardly abutted against the outer surface of the rotating roller 6 , and the trimming tool 5 and the rotating roller 6 cooperate with each other to perform trimming processing on the composite bag.

[0038] The implementation principle of this embodiment is:

[0039] The composite bag passes through the upper end surface of the fixed plate 21, and the first motor 223 is started. The first motor 223 drives the bidirectional screw rod 222 to rotate, and the distance between the two moving parts 23 is adjusted, so that the two correcting parts 24 are close to the two side edges of the composite bag. The cylinder 12 drives the mounting plate 22 to move downward, so that the lower end surface of the correcting part 24 abuts against the upper end surface of the fixed plate 21, and at the same time, the soft brush 31 of the cleaning part 3 abuts against the upper end surface of the composite bag, and the screwing handle 232 is turned to fine-tune the position of the slider 4, so that the trimming tool 5 and the position to be trimmed of the composite bag are in the same vertical plane, and the bolt 41 is loosened, and the slicing tool is rotated, so that the tip of the slicing tool away from the slider 4 abuts against the upper end of the rotating roller 6, and the bolt 41 is tightened to fix the trimming tool 5.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
