Description

Technical Field

[0001] The utility model relates to the field of packaging bag processing, in particular to a blanking device for packaging bags. Background Technique

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation and storage of goods during the production and circulation processes. It is widely used in daily life and industrial production.

[0003] After searching the patent document with the publication number CN219505550U, this patent document discloses "an automatic blanking device for packaging bags. When blanking the packaging bag, by placing the packaging bag on the top of the placement plate, pressing the cutting die above the packaging bag, then using the electric slide rail to drive the placement plate to move under the top plate, and at the same time using the hydraulic rod to drive the pressing plate and the rubber block to press the cutting die, the packaging bag can be cut by the cutting die. Through this device, the efficiency of packaging bag cutting can be effectively improved, and automatic blanking can be achieved, and manual feeding is not required, thus greatly improving the safety of the device during use.";

[0004] When the above device is operating, it is necessary to place the packaging bag to be processed on the placement plate, and then fix the packaging bag through the clamping structure. After the preparation work is completed, it is necessary for the electric slide rail to drive the placement plate to move under the hydraulic rod, and then the cutting die is pressed down by starting the hydraulic rod, so as to process the plastic bag. After the processing is completed, each structure needs to be reset to facilitate removing the processed packaging bag and putting in a new packaging bag to be processed and repeating the above operation. Such a driving structure drives the placement plate to move back and forth to process a group of packaging bags, and after the placement plate moves to the hydraulic rod, it also needs to pause and wait for the operation to be completed before the driving structure can be reset to prepare for the next processing. In this way, there will be a certain waste of time during the operation, and there is still a large room for improvement in the working efficiency of the above device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a blanking device for packaging bags in order to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A blanking device for packaging bags, including an operating table, a clamping mechanism is installed above the operating table, and a processing mechanism is also included;

[0008] The processing mechanism includes a sliding frame. Adjusting structures are installed at the front and rear ends of the sliding frame. Two telescopic rods are provided at the upper ends of the adjusting structures. The telescopic ends of the two telescopic rods are fixed with a lifting plate. A first spring is arranged on the periphery of the telescopic rod, and the upper end of the first spring is fixed to the lower end face of the lifting plate. A knife die is fixed in the middle of the lower end of the lifting plate. An upper convex platform is fixed to the upper end of the lifting plate. A fixed frame is fixed in the middle of the operating table. The inner wall of the upper end of the fixed frame is fixed with a lower convex platform. A moving structure is installed at the lower end of the sliding frame.

[0009] Preferably: The upper half of the upper convex platform is triangular in shape, and the lower half of the lower convex platform is triangular in shape.

[0010] Preferably: The moving structure includes a first screw rod. The first screw rod is rotatably connected to the upper end of the rear side of the operating table. A first motor is installed at the input end of the first screw rod. A guide rod is fixed to the upper end of the front side of the first screw rod. The sliding frame is slidably connected to the guide rod and is threadedly connected to the first screw rod.

[0011] Preferably: The adjusting structure includes a second screw rod. The second screw rod is rotatably connected to the front end of the sliding frame. A second motor is installed at the input end of the second screw rod. A guide rod is fixed to the rear end of the sliding frame. A first slider is slidably connected to the periphery of the guide rod. A first slider is threadedly connected to the periphery of the second screw rod. The positions of the two first sliders correspond to each other. The fixed ends of the two telescopic rods are respectively fixed to the upper ends of the two first sliders, and the lower end of the first spring is fixed to the first slider.

[0012] Preferably: The clamping mechanism includes a bidirectional screw rod. The bidirectional screw rod is rotatably connected inside the sliding frame. Two loading frames are threadedly connected to the periphery of the bidirectional screw rod. Clamping strips are rotatably connected to the upper ends of the loading frames. A long rod is fixed to one end of the sliding frame. Two second sliders are slidably connected to the periphery of the long rod.

[0013] Preferably: The loading frame is slidably connected to the sliding frame, and a rubber layer is provided at the lower end of the clamping strip.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] After the clamping mechanism fixes the group of packaging bags to be processed to the upper end of the sliding rack, the moving mechanism drives the movement of the packaging bags on the sliding rack. During this process, the upper convex platform will contact the lower convex platform, and the inclined surface of the triangular structure in the lower half of the lower convex platform will hold against the inclined surface of the triangular structure in the upper half of the upper convex platform. At this time, through the telescopic effect of the telescopic rod, the lifting plate and the knife die will descend, so that the knife die performs blanking processing on the packaging bag. As the moving structure continues to move, the upper convex platform will disengage from the lower convex platform. At this time, through the elasticity of the first spring, the lifting plate can be driven to reset when the upper convex platform is not limited. After the sliding rack moves to the limit position, the processed packaging bags can be removed, and then another group of packaging bags to be processed is placed. After the preparation work is completed, the moving mechanism starts to drive in the reverse direction to reset the sliding rack. During this process, the lower convex platform will hold against the upper convex platform again, causing the upper convex platform to drive the knife die at the lower end of the lifting plate to descend for processing the packaging bag. In this way, when the device makes a round trip, two groups of packaging bags can be processed, so that the working efficiency of the device is better and the energy consumption is less.

[0027] As Figures 1-6 shown, a blanking device for packaging bags includes an operating table 1, a clamping mechanism is installed above the operating table 1, and a processing mechanism is also included.

[0028] The processing mechanism includes a sliding frame 23. Adjusting structures are installed at the front and rear ends of the sliding frame 23. The adjusting structure includes a second screw rod 24. The second screw rod 24 is rotatably connected to the front end of the sliding frame 23. A second motor 25 is installed at the input end of the second screw rod 24. A guiding rod 26 is fixed to the rear end of the sliding frame 23. A first slider 27 is slidably connected to the periphery of the guiding rod 26. A first slider 27 is threadedly connected to the periphery of the second screw rod 24, and the positions of the two first sliders 27 correspond to each other. Expansion rods 28 are respectively fixed to the upper ends of the two first sliders 27. The telescopic ends of the two expansion rods 28 are fixed with a lifting plate 29. A first spring 210 is arranged on the periphery of the expansion rod 28. The upper end of the first spring 210 is fixed to the lower end surface of the lifting plate 29, and the lower end of the first spring 210 is fixed to the first slider 27. A tool die 211 is fixed to the middle of the lower end of the lifting plate 29. An upper boss 212 is fixed to the upper end of the lifting plate 29. A fixed frame 213 is fixed to the middle of the operating table 1. A lower boss 214 is fixed to the inner wall of the upper end of the fixed frame 213. A moving structure is installed at the lower end of the sliding frame 23. The moving structure includes a first screw rod 2. The first screw rod 2 is rotatably connected to the upper end at the rear side of the operating table 1. A first motor 21 is installed at the input end of the first screw rod 2. A guiding rod 22 is fixed to the upper end at the front side of the first screw rod 2. The sliding frame 23 is slidably connected to the guiding rod 22 and is threadedly connected to the first screw rod 2; through the threaded connection between the first screw rod 2 and the sliding frame 23 and the sliding connection between the sliding frame 23 and the guiding rod 22, when the first motor 21 drives the first screw rod 2 to rotate, the sliding frame 23 can be moved. Through the threaded connection between the second screw rod 24 and the first slider 27 and the sliding connection between the guiding rod 26 and the first slider 27, when the second motor 25 drives the second screw rod 24 to rotate, the first slider 27 can drive the lifting plate 29 at the telescopic end of the expansion rod 28 to move, so as to adjust the position of the tool die 211.

[0029] The clamping mechanism includes a bidirectional screw 3 which is rotatably connected inside the sliding frame 23. Two loading frames 31 are threadedly connected to the periphery of the bidirectional screw 3. The loading frames 31 are slidably connected to the sliding frame 23. The upper end of the loading frame 31 is rotatably connected to a clamping strip 32. A rubber layer is provided at the lower end of the clamping strip 32. One end of the sliding frame 23 is fixed with a long rod 33. Two second sliders 34 are slidably connected to the periphery of the long rod 33, and the positions of the two second sliders 34 correspond to the positions of the two clamping strips 32 respectively. The upper end of the second slider 34 is fixed with a second spring 35, and the upper end of the second spring 35 is fixed to the lower end face of the clamping strip 32. Through the threaded connection between the loading frame 31 and the bidirectional screw 3 and the sliding connection between the long rod 33 and the second slider 34, when the bidirectional screw 3 is rotated, the distance between the two loading frames 31 can be adjusted, so that the distance between the two clamping strips 32 can be adjusted. In this way, the device can be applied to packaging bags of various sizes. After the adjustment is completed, first lift the two clamping strips 32, then place the packaging bag to be processed on the sliding frame 23, and then release the two clamping strips 32. Through the pulling force of the second spring 35, the two clamping strips 32 can clamp the two ends of the packaging bag.

[0030] Working principle: Before the device operates, first adjust the device according to the size of the packaging bag to be processed. Through the threaded connection between the loading rack 31 and the bidirectional screw 3 and the sliding connection between the long rod 33 and the second slider 34, when the bidirectional screw 3 is rotated, the distance between the two loading racks 31 can be adjusted, so that the distance between the two clamping strips 32 can be adjusted. In this way, the device can be applied to packaging bags of various sizes. After the adjustment is completed, first lift the two clamping strips 32, then place a group of packaging bags to be processed on the sliding rack 23. Subsequently, after loosening the two clamping strips 32, through the pulling force of the second spring 35, the two clamping strips 32 can clamp the two ends of the packaging bag. After the packaging bag is fixed, the first motor 21 drives the first screw 2 to rotate. Through the threaded connection between the first screw 2 and the sliding rack 23 and the sliding connection between the sliding rack 23 and the guide rod 22, when the first motor 21 drives the first screw 2 to rotate, the packaging bag clamped on the sliding rack 23 can move. In this process, the upper convex platform 212 will contact the lower convex platform 214, and the inclined surface of the lower half triangular structure of the lower convex platform 214 will hold against the inclined surface of the upper half triangular structure of the upper convex platform 212. At this time, through the telescopic effect of the telescopic rod 28, the lifting plate 29 and the die 211 will descend, so that the die 211 can punch the packaging bag. As the sliding rack 23 continues to move, the upper convex platform 212 will disengage from the lower convex platform 214. At this time, through the elasticity of the first spring 210, the lifting plate 29 can be driven to reset when the upper convex platform 212 is not limited. When the sliding rack 23 moves to the limit position, the processed packaging bag can be removed, and then another group of packaging bags to be processed can be placed. After the preparation work is completed, the first motor 21 starts to drive in the reverse direction to reset the sliding rack 23. In this process, the lower convex platform 214 will hold against the upper convex platform 212 again, so that the upper convex platform 212 drives the die 211 at the lower end of the lifting plate 29 to descend to process the packaging bag. In this way, when the device makes a round trip, two groups of packaging bags can be processed, so that the operating efficiency of the device is better and the energy consumption is less.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
