Description

Technical Field

[0001] The utility model relates to the technical field of paper bag punching equipment, in particular to an automatic feeding paper bag punching device. Background Art

[0002] At present, after the grape bag products are formed, they need to go through the final processing procedure - punching. In the traditional punching process, workers feed the materials into the punching machine, press the punching button of the machine to punch, and then manually sort out the waste paper punched out of the grape bag, and finally package it. Due to the high quality requirements of grape bag products, the traditional punching process cannot punch more than three holes each time, and the waste generated by punching is fine and needs to be manually cleaned. According to this traditional method, the punching machine needs to be cleaned frequently and the labor intensity of the workers is high, and it is difficult to meet the requirements of high efficiency.

[0003] In Chinese patent literature, there are also some prior patents on paper bag punching machines, such as the patent number 202222825803.3 "Perforated Paper Bag Punching Machine". However, this type of patent technical solution still has some problems in structure and use, as follows: (1) Before punching, the paper bag needs to be manually placed in the bag placement groove 16 of the sliding mounting plate 3; and after punching, the paper bag needs to be manually removed from the bag placement groove 16; this method causes troublesome operation and requires manual bag placement and bag removal, which is inefficient and labor-intensive for workers. At the same time, the machine will be shut down during the bag placement and bag removal process, and continuous assembly line production cannot be achieved. (2) After the paper bag is punched, it is still necessary to manually remove the waste paper, which increases the work process and intensity, and there is also the problem of waste paper flying during the removal process. (3) The sliding mounting plate of this type of punching machine is difficult to disassemble and is often only suitable for punching holes in one size of paper bag. Because the size of the bag placement groove 16 is fixed, it can only be used to punch holes in paper bags of the same size as the bag placement groove 16, and cannot be used to punch holes in other sizes of paper bags, resulting in a narrow scope of use. If the paper bag is large, the paper bag will not fit into the bag placement groove 16. If the paper bag is small, the paper bag will shift in the bag placement groove 16, resulting in inaccurate punching positions. (4) The punching machine of this patent needs to be equipped with a protective device during operation, but this protective device only prevents the punching tool from injuring the worker's hands during punching through the protective baffle 23. It fails to protect the worker's hands from entering the punching machine, and there is still the problem of the worker's hands being crushed by other parts. The protectiveness is still insufficient and unsafe.

[0024] Example 1

[0025] The paper bag punching device described in this embodiment 1 is an automatic feeding device. Figure 1 and Figure 2As shown, it includes an automatic paper feeding conveying platform 1, a paper bag punching conveying frame 2 connected to the automatic paper feeding conveying frame, a paper bag punching plane table 3 installed on the paper bag punching conveying frame, transmission bearing wheels 4 respectively installed at both ends of the bottom of the paper bag punching conveying frame, a driving motor 5 installed at one end of the bottom of the paper bag punching conveying frame and engaged to drive the transmission bearing wheel to rotate, a feeding chain 6 installed and connected between the two transmission bearing wheels and aligned with the paper bag punching plane table at the top, a punching machine 7 installed on the paper bag punching conveying frame and located above the paper bag punching plane table and the feeding chain, and a receiving conveyor belt 8 connected to the discharge position of the paper bag punching plane table; the feeding chain is movably equipped with limit baffles 9 that are equidistantly arranged and protrude upward to form a paper bag feeding limit. The automatic paper feeding conveyor table and the receiving conveyor belt both adopt conventional conveyor belts in the industry, which respectively realize the functions of paper bag loading and unloading after punching. The two conveyor belts are aligned flatly close to the two ends of the paper bag punching table (the gap between the conveyor belt and the paper bag punching table is very small, which ensures the smooth transportation of loading and unloading materials and prevents paper bags from getting stuck or falling, etc.), and are used to connect the two ends of the paper bag punching table; the paper bag punching conveyor frame serves as the supporting frame of the paper bag punching table and the mounting bracket of the motor, transmission bearing wheel punching machine. When punching, start the drive motor to rotate, and then drive the feeding chain to circulate and transport through two transmission bearing wheels. At the same time, the automatic paper feeding conveyor will transport the paper bag to the paper bag punching flat table and finally one end of the paper bag will be blocked by the previous limit baffle; the feeding chain continues to run, and the other end of the paper bag is limited by the limit baffle turned up at the back, so that the paper bag is limited and clamped on the feeding chain and enters the punching machine. When the paper bag passes through the punching machine, the punching machine punches the paper bag; before the punched paper bag is output and enters the receiving conveyor belt, the previous limit baffle will run along the feeding chain and turn down to the paper bag punching flat table. At this time, the front end of the paper bag is not blocked and smoothly enters the receiving conveyor belt, completing the purpose of unloading and transporting to the packaging area. In the whole process, the automatic loading, punching and unloading of paper bags are realized, and a plurality of equally spaced limit baffles are arranged on the feeding chain to realize the conveying and punching limit of paper bags, and at the same time, multiple paper bags can be arranged in sequence and enter the feeding chain for feeding and punching, etc., so as to meet the requirements of continuous punching production. The limit baffle is installed movably, and the installation distance between the two limit baffles can be adjusted according to the different sizes of paper bags, so that paper bags of different sizes can be applied to this punching process; the movable installation of this limit baffle can be realized by quick insertion, quick-connect nuts and other movable structures, which is a well-known technology in the industry and will not be described in detail here.

[0026] In this embodiment 1, Figure 3 and Figure 4As shown, the punching machine includes a bottom plate 10 installed on a paper bag punching plane, a middle plate 11 fixedly installed above the bottom plate, a movable plate 12 movably installed with the middle plate and located above the middle plate, and a stamping control cylinder (not shown in the figure) for driving the movable plate to press down or reset and move upward; the bottom of the movable plate is provided with a punching needle 14 protruding downward, the middle plate is provided with a punching needle guide sleeve 15 installed in cooperation with the punching needle and allowing the punching needle to pass through, and the bottom plate is provided with a punching needle hole 16 allowing the punching needle to be pressed down and enter; the bottom of the movable plate is also provided with a positioning guide column 17 protruding downward and movably passing through the middle plate and penetrating into the bottom plate, and a positioning guide column sleeve 18 installed in cooperation with the positioning guide column is provided between the middle plate and the bottom plate; a stamping guide column 20 is also provided between the movable plate and the bottom plate, and a return spring 21 is provided on the stamping guide column sleeve. The bottom plate of the punching machine is fixed. The movable plate is pressed down by the stamping control cylinder, and the movable plate drives the punching needle to press down. The punching needle passes through the middle plate and finally passes through the paper bag placed on the bottom plate and then enters the punching needle hole to form a hole in the paper bag. After punching, the stamping control cylinder is closed, and the movable plate and the punching needle are reset upward by the return spring to complete the punching process. The middle plate is used as a stroke limit for the movable plate to press down. After the movable plate reaches the specified downward stroke, it is supported by the middle plate so that the movable plate is no longer pressed down, realizing the stroke limit of the movable plate. According to the number and position requirements of the punching holes of the paper bag, one or more punching needles can be installed to achieve the punching effect; the corresponding guide column and guide column sleeve are to achieve the smooth operation of the punching and the excellent effect of the motion trajectory.

[0027] The feeding chain is driven by a driving motor to feed the punching machine, and holes are punched through the punching action of the punching machine. In this way, the feeding and punching can be coordinated and operated automatically without manual operation.

When the punch needle is inserted into the punch needle hole, the punch needle also presses the waste paper formed after punching into the punch needle hole. When the punch needle is inserted to the lowest position of the punch needle hole, the waste paper will be pressed into the waste paper outlet hole, and then the waste paper will fall from the waste paper outlet hole to the lower inclined surface of the paper bag punching flat table. Due to the effect of gravity, the waste paper will slide down along the lower inclined surface and finally slide into the waste collection frame to complete the collection of the waste paper. In this way, the purpose of automatically dropping and collecting waste paper in the paper bag during the punching process can be achieved. Two processes are completed by punching once, and there is no need for the subsequent waste paper removal and collection processes. It is simple, efficient and convenient.

The feeding chain is a double chain structure that can achieve the effect of smooth feeding and accurate positioning of the paper bag, and can accurately limit the paper bag to enter the punching machine to achieve accurate punching; when the feeding chain is running, it needs to be transported along the upper and lower surfaces of the paper bag punching plane. The plane table through groove can make the feeding chain smoothly transport and move without forming obstacles, and at the same time, the limit baffle can be protruded out of the paper bag punching plane; when the limit baffle enters the punching machine, it will also enter the middle plate through groove and the bottom plate through groove, achieving the effect of the limit baffle passing through the punching machine smoothly.

[0033] In this embodiment 1, Figure 5 , Figure 6 and Figure 7 As shown, the outer sides of the movable plate, the middle plate and the bottom plate are all recessed inwards to form a punching machine plate recess 29 which is installed corresponding to the frame opening of the waste collection frame and outputs waste paper into the waste collection frame. The waste collection frame is inserted into the punching machine plate recess, and its frame opening is aligned with the punching machine plate recess, so that when the waste paper slides from the lower inclined surface of the paper bag punching flat table, it can slide along the lower inclined surface to the punching machine plate recess and finally slide into the waste collection frame for waste paper collection.

[0034] In this embodiment 1, the paper bag punching conveyor frame is also provided with a protective cover 30 for covering the punching machine. The protective cover completely covers the punching machine, realizes all-round protection, ensures the safety of punching, and improves the protection.
