Description

Technical Field

[0001] This utility model relates to the technical field of cutting devices for pre-made bag packaging machines, and in particular to a cutting device for pre-made bag packaging machines that facilitates waste removal. Background Technology

[0002] With the rapid development of the packaging industry, pre-made bag packaging machines play an important role in the packaging of various products. The cutting device of existing pre-made bag packaging machines usually consists of a cutter support, a fixed blade fixed to the cutter support, and a moving blade slidably connected to the cutter support. Its working principle is that the moving blade reciprocates relative to the fixed blade under the drive of a hydraulic cylinder, thereby cutting and segmenting the pre-made bag. A qualified product slide plate is set below the gap between the fixed blade and the moving blade to guide the cut pre-made bags out. During the cutting process of the pre-made bags by the fixed blade and the moving blade, waste such as debris and scraps will inevitably be generated.

[0003] However, existing pre-made bag packaging machine cutting devices lack waste collection components in their cutter supports, fixed blades, moving blades, and qualified product chute. Waste easily accumulates on the qualified product chute, requiring frequent manual cleaning, which not only increases labor costs but also affects production continuity. During heavy production periods, the waste accumulation problem becomes more pronounced, potentially leading to equipment malfunctions and severely impacting production efficiency and product quality. Furthermore, untimely waste collection may result in waste being mixed into subsequently produced pre-made bags, causing product defects and reducing the product qualification rate. Therefore, this paper proposes a pre-made bag packaging machine cutting device that facilitates waste removal. Utility Model Content

[0004] The main objective of this invention is to provide a pre-made bag packaging machine cutting device that facilitates waste removal, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pre-made bag packaging machine cutting device for easy waste removal includes a cutter support, a fixed blade fixedly connected to the cutter support, a movable blade slidably connected to the cutter support, and an arc-shaped qualified product slide. The qualified product slide is located below the gap between the fixed blade and the movable blade. The qualified product slide has a number of waste perforations densely arranged on it, and a waste collection box is fixedly connected to the bottom of the qualified product slide.

[0007] A micro-negative pressure debris adsorption generating device is fixedly connected to the top of the waste collection box on the side away from the qualified product chute. The micro-negative pressure debris adsorption generating device mainly consists of a rectangular air duct and several exhaust fans. The rectangular air duct is fixedly connected to the top of the waste collection box, and the several exhaust fans are arranged in a straight line and installed on one side of the rectangular air duct.

[0008] Preferably, the rectangular air duct is fitted into the connecting frame, and an air filter is installed at an angle inside the connecting frame.

[0009] Preferably, a second blade holder is fixedly installed in the inner frame of the cutter holder. A miniature electric push cylinder and two telescopic rods are fixedly installed on the second blade holder. The end of the push rod in the miniature electric push cylinder and the end of the movable rod in the telescopic rod are vertically connected to a first soft brush. The bristles at the lower end of the first soft brush are in contact with the upper part of the fixed blade.

[0010] Preferably, a second soft brush is fixedly installed in the inner frame of the cutter holder, and the bristles at the lower end of the second soft brush are positioned on the path above the moving blade.

[0011] Preferably, a first blade holder is fixedly connected to one side of the moving blade, and a hydraulic cylinder and two guide cylinders are vertically connected between the first blade holder and the inner frame of the cutting blade support. A guide column is telescopically installed inside the guide cylinder, and the guide cylinder and the guide column are fixedly connected to the cutting blade support and the first blade holder, respectively.

[0012] Preferably, the inner cavity of the connecting frame is provided with an inclined guide bottom surface that gradually slopes downward from the outside to the inside.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. High-efficiency waste collection:

[0015] Several waste material perforations are set on the qualified product slide below the gap between the fixed blade and the moving blade. A waste material collection box is fixedly connected to the bottom of the qualified product slide to collect the debris, scraps and other waste materials that fall through the perforations on the qualified product slide. Several exhaust fans are set at the top of the waste material collection box to provide a weak suction to the inner cavity of the waste material collection box, so that the waste material perforations on the qualified product slide generate suction. This can effectively speed up the collection of small-sized debris or scraps and other waste materials. Compared with relying solely on the weight of the waste material for collection, it significantly improves the waste material collection efficiency, avoids the accumulation of waste material in the device, reduces the frequency and workload of manual cleaning, and helps to improve the continuity and stability of production.

[0016] 2. Optimize tool cleaning effect:

[0017] The second soft brush is positioned on the travel path above the moving blade. Each time the moving blade moves away from the stationary blade, it can promptly sweep away the debris adhering to the moving blade, allowing it to fall into the qualified product slide 8 and be collected, thus preventing waste residue on the blade from affecting the subsequent cutting quality and efficiency.

[0018] A miniature electric push cylinder drives the first soft brush to clean and sweep away debris adhering to the blade of the fixed blade according to the extension path of the two telescopic rods. This ensures that the fixed blade always maintains a good cutting condition, reduces problems such as decreased cutting accuracy and product quality defects caused by waste adhering to the blade, extends the blade's service life, and reduces production costs.

[0019] 3. Guarantee product quality:

[0020] The above-mentioned waste cleaning and collection measures can effectively prevent waste residue from causing secondary pollution or physical damage to prefabricated bag products, ensure that the quality of each prefabricated bag meets the standards, improve the product qualification rate, enhance the product's competitiveness in the market, help enterprises establish a good brand image and market reputation, and bring economic benefits to enterprises.

[0021] 4. Enhance the stability and reliability of the cutting device of this pre-made bag packaging machine, which facilitates waste removal:

[0022] The air entering the exhaust fan is filtered by an air filter, and the inclined guide surface of the connecting frame and the bottom of the rectangular air duct smoothly guides the debris into the waste collection box. This effectively prevents impurities from accumulating in the micro-negative pressure debris adsorption device, avoiding the impact of impurity accumulation on the normal operation of components such as the exhaust fan. This ensures the stable operation of the entire pre-made bag packaging machine cutting device, which is easy to clean, reduces the failure rate, lowers maintenance costs and downtime, and improves production efficiency.

[0028] 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.

[0029] like Figures 1-4 As shown, a pre-made bag packaging machine cutting device for easy waste disposal includes a cutter support 1, a fixed blade 2 fixedly connected to the cutter support 1, a movable blade 12 slidably connected to the cutter support 1, and an arc-shaped qualified product slide 8. The qualified product slide 8 is located below the gap between the fixed blade 2 and the movable blade 12. Several waste perforations 9 are densely arranged on the qualified product slide 8. The inner size of the waste perforations 9 is larger than the size of waste such as scraps and offcuts. A waste collection box 7 is fixedly connected to the bottom of the qualified product slide 8.

[0030] refer to Figure 2 and Figure 3 A first blade holder 10 is fixedly connected to one side of the moving blade 12. A hydraulic cylinder 6 and two guide cylinders 11 are vertically connected between the first blade holder 10 and the inner frame of the cutter support 1. The cylinder body of the hydraulic cylinder 6 and the two guide cylinders 11 are fixedly connected to the inner frame of the cutter support 1. A guide column 13 is telescopically installed inside the guide cylinder 11. The guide cylinder 11 and the guide column 13 are fixedly connected to the cutter support 1 and the first blade holder 10, respectively. The end of the piston rod in the hydraulic cylinder 6 and the guide column 13 are fixedly connected to the inner frame of the first blade holder 10. By extending and retracting the piston rod in the hydraulic cylinder 6, the moving blade 12 is driven to move away from or closer to the fixed blade 2 to perform reciprocating shearing action.

[0031] refer to Figure 2 and Figure 3 A second soft brush 14 is fixedly installed in the inner frame of the cutter bracket 1. The bristles at the lower end of the second soft brush 14 are set on the path above the blade of the moving blade 12. Each time the moving blade 12 moves away from the fixed blade 2, the second soft brush 14 can sweep away the debris adhering to the blade of the moving blade 12 and let it fall onto the qualified product slide 8.

[0032] refer to Figure 1A second blade holder 15 is fixedly installed in the inner frame of the cutter bracket 1. A miniature electric push cylinder 4 and two telescopic rods 5 are fixedly installed on the second blade holder 15. The end of the push rod in the miniature electric push cylinder 4 and the end of the movable rod in the telescopic rod 5 are vertically connected to a first soft brush 3. The cylinder body in the miniature electric push cylinder 4 and one end of the telescopic rod 5 are fixedly connected to the second blade holder 15. The end of the push rod in the miniature electric push cylinder 4 and the other end of the telescopic rod 5 are fixedly connected to the first soft brush 3. The bristles at the lower end of the first soft brush 3 are positioned above the blade of the fixed blade 2. By extending and retracting the push rod in the miniature electric push cylinder 4, the first soft brush 3 is driven to clean and sweep away the debris adhering to the blade of the fixed blade 2 according to the extension and retraction path of the two telescopic rods 5, and the debris falls onto the qualified product slide 8.

[0033] refer to Figure 4 A micro-negative pressure debris adsorption device is fixedly connected to the top of the waste collection box 7, away from the qualified product chute 8. The micro-negative pressure debris adsorption device mainly consists of a rectangular air duct 17 and several exhaust fans 16. The rectangular air duct 17 is fixedly connected to the top of the waste collection box 7, and the several exhaust fans 16 are arranged in a straight line on one side of the rectangular air duct 17. The suction end of the several exhaust fans 16 is directly facing the upper end of the qualified product chute 8, providing a weak suction force to the inner cavity of the waste collection box 7. This suction force is only effective for small-sized debris or scraps and has little impact on qualified pre-cut bags, because qualified pre-cut bags are larger and relatively heavier, and the potential energy generated by their fall is greater than that generated by waste, so the impact is smaller. With the negative pressure suction force provided by the several exhaust fans 16, suction force can be provided to the several waste perforations 9 on the qualified product chute 8, increasing the efficiency of waste collection box 7 in collecting waste.

[0034] refer to Figure 4 A rectangular air duct 17 is embedded and fixedly installed in a connecting frame 18. An air filter 19 is installed at an angle inside the connecting frame 18. The air filter 19 is gradually tilted to the left from top to bottom to filter the air and prevent impurities from entering components such as the exhaust fan 16 and affecting their normal operation. An inclined guide bottom surface 20 is provided at the bottom of the inner cavity of the connecting frame 18, which is gradually tilted downward from the outside to the inside. The inner bottom surface of the rectangular air duct 17 is also gradually tilted downward from the outside to the inside. This is used to slide debris entering the inner frame of the connecting frame 18 and the rectangular air duct 17 down along the inclined guide bottom surface 20 into the waste collection box 7, further ensuring the effective collection of waste and preventing it from accumulating in the device and affecting the operation of the equipment.

[0035] In this embodiment, when the fixed blade 2 and the moving blade 12 cut the pre-made bag into segments, the debris or scraps generated during the cutting of the pre-made bag will fall naturally to the qualified product slide 8 by gravity. The debris or scraps are then collected into the waste collection box 7 through the waste perforation 9 on the qualified product slide 8. At the same time, the efficiency and effect of waste cleaning and collection are further improved by the micro-negative pressure debris adsorption device and the soft brush structure, which effectively solves the problem of low waste cleaning and collection efficiency in the cross-cutting mechanism of the existing pre-made bag packaging machine.
