Description

Technical Field

[0001] The present application relates to the technical field of punching machines, and in particular to a packaging film punching machine. Background Art

[0002] Packaging film is used for wrapping to make the package more stable and tidy. Plastic packaging, especially composite plastic flexible packaging, has been widely used in foreign trade export, hardware, plastic chemicals, building materials, food, and pharmaceutical industries. According to the packaging requirements of different products, the packaging film needs to be perforated. For example, for the packaging of hardware products, holes need to be punched in the packaging film for exhaust to improve the convenience and efficiency of boxing or bagging. Vegetable packaging film also needs to be perforated to maintain ventilation.

[0003] The existing packaging film punching machine includes an operating table, a frame, a cylinder punching device slidably connected to the frame, a photoelectric door for detecting holes in the packaging film and controlling the cylinder punching, a conveying assembly and a limiting support roller. A pressing frame for flattening the packaging film and scraping off some of the debris on it is arranged above the conveying assembly. The debris generated by punching is easy to adhere to the driving chain, support roller and frame. If it is not cleaned for a long time, it is easy to accumulate and block the mechanical transmission or pad the bottom of the packaging film, resulting in a decrease in the punching accuracy.

[0004] In view of the above-mentioned related problems, the inventors proposed a packaging film punching machine, which can separate the debris generated by punching from the packaging film and collect them together. Utility Model Content

[0005] In order to reduce the situation where debris generated by punching accumulates and blocks the machine, hinders mechanical transmission or reduces the punching accuracy, the present application provides a packaging film punching machine.

[0006] The present application provides a packaging film punching machine, which adopts the following technical solution:

[0007] A packaging film punching machine comprises a machine base, a guide roller assembly rotatably connected to the side wall of the machine base, a punching device fixedly mounted on the upper wall of the machine base, a scraper assembly and a waste collecting device arranged on the lower side of the punching device. The guide roller assembly is used to convey the packaging film so that the packaging film passes through the punching device and the scraper assembly in sequence. The scraper assembly comprises a first scraper brush fixedly mounted on the machine base for cleaning the upper surface of the packaging film and a second scraper brush fixedly mounted under the machine base for cleaning the lower surface of the packaging film.

[0008] By adopting the above technical scheme, a punching device, a scraper assembly and a guide roller assembly are sequentially arranged on the upper side of the machine base. After the punching device punches the packaging film, part of the circular hole waste generated by the punching falls directly to the waste collecting device, part falls to the upper side of the packaging film, and part adheres to the lower side of the packaging film due to static electricity. The first scraper brush can scrape the circular hole waste that falls on the upper side of the packaging film into the waste collecting device, and the second scraper brush can scrape the circular hole waste that adheres to the lower side of the packaging film into the waste collecting device. The guide roller assembly is used to flatten and continue to convey the punched packaging film.

[0009] Optionally, the first scraper brush is in an eight-shaped shape, and the middle of the first scraper brush protrudes toward a side close to the punching device.

[0010] By adopting the above technical solution, the first scraper brush in an eight-shaped shape will give the round hole waste a resistance perpendicular to the first scraper brush on the running plane of the packaging film, and the packaging film will give the round hole waste a friction force along the movement direction of the packaging film. The combined force of the two forces is toward both sides of the packaging film. Finally, the round hole waste can be scraped off along the edges of both sides of the packaging film to the waste collection device.

[0011] Optionally, the waste collecting device includes a conveying trough for receiving the round hole waste dropped by the punching and scraped by the scraping assembly, a discharge trough tightly connected to one end of the conveying trough, and a drawing assembly for drawing out the round hole waste in the discharge trough.

[0012] By adopting the above technical solution, the round hole waste is transported from the conveying trough to the material discharge trough, and the extraction component can extract the round hole waste in the material discharge trough.

[0013] Optionally, the waste collection device includes an anti-static component provided to reduce static electricity, and the anti-static component includes a grounding wire fixedly connected to the outer wall of the conveying trough and an ion wind rod fixedly connected to the inner wall of the discharge trough.

[0014] By adopting the above technical solution, the anti-static component can weaken the electrostatic effect generated by the device on the round-hole waste, prevent the round-hole waste from sticking to the feed trough and the discharge trough and being difficult to move. The grounding wire conducts the static charge generated by the conveyor trough into the earth, and the ion wind rod can neutralize the charge in the discharge trough to balance the charge and play an anti-static role.

[0015] Optionally, the ion wind rod is a copper material ion wind rod.

[0016] By adopting the above technical solution, the copper ion wind rod has good electrical conductivity and is cheap.

[0017] Optionally, the conveying trough includes a conveyor belt, which is located at the bottom of the conveying trough, and one end of the conveyor belt is connected to the discharge trough.

[0018] By adopting the above technical solution, the conveyor belt is used to transport the round hole waste that falls into the feeding trough to the unloading trough.

[0019] Optionally, a third scraper brush is fixedly connected to the inner wall of the feeding trough, and the third scraper brush abuts against one end of the conveyor belt close to the discharge trough.

[0020] By adopting the above technical solution, the third scraper brush can scrape the round hole waste on the conveyor belt into the discharge trough, preventing the round hole waste from continuing to move to the bottom of the conveyor belt along with the conveyor belt.

[0021] Optionally, a photoelectric door is provided on a side of the upper wall of the machine base away from the punching device along the conveying direction of the packaging film.

[0022] By adopting the above technical solution, a device capable of detecting the punching holes on the packaging film is provided in the photoelectric gate, and when the photoelectric gate detects the punching holes on the packaging film, the cylinder can be controlled to punch the packaging film again.

[0023] Optionally, the punching device includes a sliding rod and a plurality of cylinders slidably connected to the upper side of the sliding rod, and the plurality of cylinders are distributed at intervals.

[0024] By adopting the above technical solution, the cylinder is slidably connected to the slide rod, so that the punching interval on the packaging film can be adjusted.

[0025] Optionally, the scraper assembly includes a first supporting roller located below the punching device, and the first supporting roller is fixedly connected to the machine base.

[0026] By adopting the above technical solution, the first supporting roller supports the packaging film, so that the punching device punches holes in the packaging film more stably.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. After the punching device punches the packaging film, the first scraper brush can scrape the round hole waste falling on the upper side of the packaging film into the waste collection device, and the second scraper brush can scrape the round hole waste adhering to the lower side of the packaging film into the waste collection device, so as to prevent the round hole waste from being scattered and left on the frame at will.

[0029] 2. The anti-static component can reduce the static electricity generated between the waste collection device and the round hole waste, so that the collected round hole waste can be better transported away.

[0030] 3. The punching cylinder is slidably connected to the slide rod to change the interval between the punching holes on the packaging film to meet the punching requirements of different packaging films. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0038] This embodiment discloses a packaging film punching machine, such as Figure 1 As shown, it includes a machine base 1, a punching device 2 for punching holes in a packaging film, a photoelectric gate 3 for detecting holes in the packaging film to control the punching device 2 to punch holes, a guide roller assembly 4 for flattening and conveying the packaging film, a waste collecting device 6 for collecting waste circular holes in the packaging film punched out by the punching device 2, and a scraping assembly 5 for scraping off the waste circular holes adhered to the packaging film, the photoelectric gate 3 is located at one end away from the punching device 2 along the conveying direction of the packaging film, the guide roller assembly 4 is located at one end of the photoelectric gate 3 away from the punching device 2, and the waste collecting device 6 is located below the machine base 1 and directly below the punching device 2.

[0039] like Figure 2 As shown, the punching device 2 includes two slide bars 23 fixed to the machine base 1, a plurality of block molds 22 slidably connected to the slide bars 23 and evenly distributed, and a cylinder 21 fixed to each block mold 22 for punching the packaging film. The two slide bars 23 are perpendicular to the conveying direction of the packaging film and are placed parallel to each other. The cylinder 21 is vertically penetrated through the block mold 22 and the punching of the cylinder 21 is facing the packaging film.

[0040] In order to better fix the block mold 22 on the slide rod 23 to increase the stability of the punching of the cylinder 21, each side wall of the block mold 22 is threadedly connected with a nut 24, and the nut 24 passes through the side wall of the block mold 22 and abuts against the slide rod 23. When the punching position is determined, tighten the nut 24 to make the connection between the quick-release mold and the slide rod 23 more stable.

[0041] like Figure 1 As shown, the waste collecting device 6 includes a conveying trough 61 for receiving the round hole waste scraped by the scraping assembly 5, a discharge trough 62 for receiving and collecting the round hole waste conveyed by the conveying trough 61, and a drawing assembly 63 for drawing the round hole waste from the discharge trough 62. The conveying trough 61 is located at the lower side of the machine base 1 and directly below the punching device 2, the discharge trough 62 is located at one end of the conveying trough 61, and the drawing assembly 63 is connected to the discharge trough 62.

[0042] like Figure 3 As shown, the scraper assembly 5 includes a first scraper brush 51 for scraping the round hole waste material adhering to the upper side of the packaging film to the conveying trough 61, and a second scraper brush 52 for scraping the round hole waste material adhering to the lower side of the packaging film to the conveying trough 61. The first scraper brush 51 is fixed to a support frame 53, the support frame 53 is fixed to the machine base 1 on both sides of the packaging film, and the second scraper brush 52 is fixed to the machine base 1 on both sides of the packaging film. The first scraper brush 51 is located above the packaging film and abuts against the packaging film, and the second scraper brush 52 is located below the packaging film and abuts against the packaging film. The first scraper brush 51 and the second scraper brush 52 are both located on the side away from the punching device 2 along the conveying direction of the packaging film.

[0043] In order to effectively scrape the round hole waste above the packaging film into the conveying trough 61, the first scraper brush 51 is in an eight-shaped shape, with one protruding end facing the punching device 2. When the round hole waste moves to the first scraper brush 51, the eight-shaped first scraper brush 51 will give the round hole waste a resistance perpendicular to the first scraper brush 51 on the running plane of the packaging film, and the packaging film will give the round hole waste a friction force along the movement direction of the packaging film. The combined force of the two forces is toward both sides of the packaging film. Finally, the round hole waste can be scraped down to the conveying trough 61 along the edges of both sides of the packaging film.

[0044] In order to enhance the stability of punching and the stability of the first scraper brush 51 and the second scraper brush 52 in scraping the packaging film, the scraper assembly 5 further includes a first support roller 54 located below the packaging film for supporting the packaging film. The first support roller 54 is located on the other side of the second scraper brush 52 relative to the punching device 2 and is placed parallel to the second scraper brush 52. The first support roller 54 abuts against the packaging film. When the packaging film is transported forward, with the support of the first support roller 54, the packaging film near the punching device 2 is prevented from shaking significantly.

[0045] The conveying trough 61 includes a conveyor belt 611 for transporting the round hole waste to the lower material trough 62. One end of the conveyor belt 611 is connected to the lower material trough 62 and the rotation direction is toward the side of the lower material trough 62. One end of the outer wall of both sides of the conveying trough 61 is fixed to the two sides of the conveyor belt 611, and the other end extends toward the packaging film and away from the two sides of the conveyor belt 611. The outer wall of the conveying trough 61 near one end of the punching device 2 abuts against the side of the first support roller 54 away from the second scraper brush 52. A driving motor (not shown in the figure) is fixed to the outer wall of the end of the conveying trough 61 away from the lower material trough 62, which is used to drive the conveyor belt 611 to rotate.

[0046] In order to reduce the impact of static electricity on the transportation of round hole waste, such as Figure 1 As shown, two grounding wires 612 are symmetrically fixed to the outer wall of one side of the conveying trough 61 . The grounding wires 612 usually have excellent conductive properties, such as copper, aluminum, etc. In this embodiment, copper wires are used as the grounding wires 612 .

[0047] In order to prevent the part of the round hole waste on the conveyor belt 611 from continuing to rotate with the conveyor belt 611 to the bottom of the conveyor belt 611 and falling to the ground when the conveyor belt 611 is transported to the discharge chute 62, as shown in FIG. Figure 4 As shown, a third scraper brush 613 is provided at one end where the transmission belt is connected to the discharge chute 62. Both ends of the third scraper brush 613 are fixedly connected to both sides of the conveyor belt 611. The third scraper brush 613 abuts against the conveyor belt 611, and can scrape the round hole waste when the conveyor belt 611 moves above the discharge chute 62 into the discharge chute 62.

[0048] In order to prevent a large amount of round hole waste from adhering to the inner wall of the feeding trough 62 and the periphery of the third scraping brush 613 connected to the feeding trough 62 due to static electricity, Figure 5 As shown, an ion wind rod 621 is fixedly connected in the feed chute 62 , and the ion wind rod 621 is penetrated in the feed chute 62 . The ion wind rod 621 is connected to a high voltage generator 622 on the ground through a wire 623 .

[0049] The ion wind rod 621 can be made of copper or aluminum. This embodiment uses the ion wind rod 621 made of copper for illustration.

[0050] like Figure 1 As shown, the material discharge chute 62 is connected to the conveying chute 61 in a sealed manner, and the material extraction assembly 63 is fixedly connected to the material discharge chute 62. The material extraction assembly 63 includes an exhaust fan 631 for extracting materials from the material discharge chute 62, an exhaust pipe 632 fixed to the outer wall of the material discharge chute 62, and a storage chute 633 for storing round hole waste materials. The outer wall of the storage chute 633 is provided with a drawer 6331, which can take out the round hole waste materials inside the storage chute 633. The storage chute 633 is located at one end of the exhaust pipe 632 away from the material discharge chute 62 and is connected to the exhaust pipe 632.

[0051] like Figure 3As shown, the guide roller assembly 4 is located on the side of the photoelectric gate 3 away from the punching device 2. The guide roller assembly 4 includes a flattening roller 41 located above the packaging film, a second supporting roller 42 located below the packaging film, and film-drawing double rollers 43 located on the upper and lower sides of the packaging film and placed parallel to each other. The height of the second supporting roller 42 is higher than the flattening roller 41 and the film-drawing double rollers 43, and the packaging film abuts against the guide roller assembly 4. The punched packaging film is transported toward the guide roller assembly 4, passing through the flattening roller 41, the second supporting roller 42 and the film-drawing double rollers 43 in sequence, so that the packaging film can be more smoothly transported to the next process.

[0052] It is understandable that the photoelectric gate 3 is provided with a device capable of detecting the punching of the packaging film and then controlling the cylinder 21 to punch again. The detection device is a prior art and will not be repeated in this application.

[0053] It is understandable that the ion wind rod 621 and the high voltage generator 622 are used together to quickly neutralize static electricity. This technology is existing technology and will not be repeated in this application.

[0054] like Figure 1 As shown, during the use of the embodiment of the present application, the packaging film moves from the punching device 2 to the guide roller assembly 4 on the machine base 1, and is sequentially conveyed to the next process through the punching device 2, the first scraper brush 51, the photoelectric gate 3 and the guide roller assembly 4. The waste collection device 6 is located below the punching device 2. When the packaging film passes through the punching device 2, the cylinder 21 punches the packaging film under the support of the first support roller 54. When the punched packaging film moves to the photoelectric gate 3, the detection device in the photoelectric gate 3 can detect the holes on the packaging film and control the cylinder 21 to punch again. Part of the waste generated by punching falls directly into the conveying trough 61, and the other part remains on the upper side of the packaging film and is scraped down into the conveying trough 61 by the first scraper brush 51. The round hole waste falling into the conveying trough 61 is conveyed to the unloading trough 62 by the conveyor belt 611, and then extracted to the storage trough 633 by the extraction assembly 63.

[0055] The implementation principle of this embodiment is:

[0056] The first scraper brush 51 is in an eight-shaped shape, with the middle part protruding toward the side close to the punching device 2. When the round hole waste on the upper side of the packaging film moves to the first scraper brush 51, the first scraper brush 51 blocks the round hole waste from continuing to move along the moving direction of the packaging film. The first scraper brush 51 applies a resistance perpendicular to the first scraper brush 51 to the round hole waste along the moving direction of the packaging film. The packaging film applies a friction force to the round hole waste along the moving direction of the packaging film. The combined force of the two forces is toward both sides of the packaging film, which can make the round hole waste eventually fall from the two ends of the first scraper brush 51 into the conveying trough 61.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
