Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, specifically to a cutting and blanking device for woven bag production. Background Technology

[0002] Woven bags are plastic packaging bags made from polypropylene or polyethylene. Domestically, polypropylene is mainly used, resulting in bags that are thick and sturdy. Internationally, polyethylene is the primary material, offering resistance to low temperatures and acids / alkalis. In the production and processing of woven bags, a cutting device precisely and efficiently cuts rolls of woven fabric into individual woven bag blanks according to preset dimensions and requirements, providing standardized semi-finished products for subsequent processes such as bottom sewing, printing, and packaging.

[0003] In the prior art, when cutting woven bags, the woven bags are generally transported to the cutting position by a conveyor belt for cutting. When the cutting station is transferred to the stacking station, the bags may fall freely or be subject to drop differences, resulting in displacement, rolling and wrinkling of the bags. This makes it difficult to form a neat stack, inconvenient for unloading and stacking, and the effect is not good. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cutting and blanking device for woven bag production, so as to solve the problems mentioned in the background technology. This utility model has a reasonable structure, neat material stacks, and convenient material cutting and stacking.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 As shown, this utility model provides a technical solution: a cutting and blanking device for woven bag production, comprising: The frame 1 has a conveyor belt 2 on top and a cutting blade 6 located on one side of the conveyor belt 2 above the frame 1. A rotating shaft 11 is installed at one end of the cutter 6 on the frame 1, and a feed plate 9 is provided on the side wall of the rotating shaft 11; The frame 1 is equipped with a drive unit for rotating the rotating shaft 11, so that the feeding plate 9 can be flipped. This design uses the conveyor belt 2 to transport the woven bags to the appropriate cutting position, and the cutting blade 6 to cut the woven bags. Before cutting, the woven bags are attached to the side of the feeding plate 9 away from the frame 1. After the woven bags are cut, the drive assembly 13 drives the rotating shaft 11 to rotate, and the rotation of the rotating shaft 11 drives the feeding plate 9 to rotate and flip, flipping the woven bags from a vertical state to a horizontal state, which is convenient for stacking and enhances the neatness of the stacking, resulting in good performance. In particular, the feeding plate 9 is initially in a vertical state. After the woven bags are cut, the feeding plate 9 flips to a horizontal state, and the flipping and feeding of the woven bags is achieved by repeating this process.

[0018] Reference Figure 1 and Figure 3 The drive unit includes a drive assembly and two upright plates 10. The two upright plates 10 are symmetrically installed on both sides of the frame 1. Each of the two upright plates 10 is equipped with a bearing 101. The two ends of the rotating shaft 11 are respectively connected to the two upright plates 10 through the bearings 101.

[0019] Reference Figure 1 and Figure 4The drive assembly 13 includes a mounting base 131 disposed on any side of the upright plate 10, and a drive component 132 connected to the output shaft and the rotating shaft 11 is mounted on the mounting base 131. The driving component 132 is a rotary cylinder. This design uses the driving component 132 to drive the rotating shaft 11 to rotate, and the rotating shaft 11 drives the feeding plate 9 to rotate, thus performing a flipping and feeding operation on the woven bag. The driving component 132 is a rotary cylinder, and the rotation limit angle can be adjusted by the threaded post on it. The rotary cylinder can also be replaced by a motor or other components that can drive the rotating shaft 11 to rotate. It is only necessary to drive the rotating shaft 11 to flip the feeding plate 9 from a vertical state to a horizontal state, and switch between vertical and horizontal states repeatedly.

[0020] Reference Figure 1 The side wall of the feed plate 9 has multiple through slots 12, which improves the rationality of the design.

[0021] Reference Figure 1 and Figure 2 The frame 1 has a guide plate 8 on its side wall for guiding the cut woven bags to the surface of the cutting plate 9. A cushioning pad 14 is provided on the side of the guide plate 8 closest to the cutting plate 9. This design uses the guide plate 8 to facilitate guiding the woven bags to the surface of the cutting plate 9 away from the frame 1; and the cushioning pad 14 to cushion the cutting plate 9. The edges of the cutting plate 9 are chamfered to prevent scratches on the woven bags.

[0022] Reference Figure 2 and Figure 3 The frame 1 is equipped with a pressure roller 3 for pressing and guiding the woven bags conveyed by the conveyor belt 2. The frame 1 is also equipped with a pressing assembly 4 for driving the pressure roller 3 to move vertically. This design uses the pressing assembly 4 to drive the pressure roller 3 to contact the upper surface of the woven bag, which, in conjunction with the conveyor belt 2, facilitates the guiding and conveying of the woven bags.

[0023] Reference Figure 2 The pressing assembly 4 includes a support frame 42 mounted on top of the frame 1. A pressing electric push rod 43 is mounted on the top of the support frame 42. A connecting frame 41, rotatably connected to the pressure roller 3, is mounted on the telescopic shaft of the pressing electric push rod 43. The rotatable connection is achieved by a bearing at the connection point. This design allows the pressing electric push rod 43 in the pressing assembly 4 to move the connecting frame 41 vertically, which in turn moves the pressure roller 3 vertically, facilitating adjustment of the contact between the pressure roller 3 and the upper surface of the woven bag.

[0024] Reference Figure 3 The frame 1 is equipped with a drive cutting assembly 5 for driving the cutting blade 6 to move vertically to cut the woven bag; The drive cutting assembly 5 includes a connecting frame 52 mounted on top of the frame 1, and a lifting electric push rod 51 connected to the cutting blade 6 is mounted on top of the connecting frame 52. This design drives the cutting blade 6 to move vertically to cut the woven bag by operating the lifting electric push rod 51 in the drive cutting assembly 5.

[0025] Reference Figure 2 and Figure 3 The top of the frame 1 has a groove 7 for avoiding the cutting blade 6. A support plate 16 is provided on the lower side of the inner wall of the groove 7, and a support electric push rod 15 connected to the support plate 16 is provided at the bottom of the frame 1. This design avoids the cutting blade 6 through the groove 7; the operation of the support electric push rod 15 drives the support plate 16 to move vertically, and the upper end surface of the support plate 16 is flush with the upper end surface of the frame 1, providing support and guidance for the woven bag; when the woven bag needs to be cut, the operation of the support electric push rod 15 drives the support plate 16 back to the initial position.

[0026] Reference Figures 1-4 As an embodiment of this utility model: when it is necessary to cut the woven bag, the worker uses the conveyor belt 2 and the pressure roller 3 to transport the woven bag. When the woven bag moves to a suitable position where it contacts the surface of the feed plate 9 away from the frame 1, the lifting electric push rod 51 in the cutting assembly 5 drives the cutting blade 6 to cut the woven bag.

[0027] After the woven bags are cut, the drive component 132 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 causes the feeding plate 9 to rotate and flip, turning the woven bags from a vertical state to a horizontal state, which facilitates stacking and enhances the neatness of the stacking, resulting in good performance. After one stacking is completed, the feeding plate 9 returns to the initial position, and the stacking operation is repeated, which improves the practicality of this utility model.
