Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to a device for recycling edge materials in packaging bag production. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production of various daily necessities. They are widely used in daily life and industrial production. When processing plastic packaging bags, it is necessary to recycle the processing scraps.

[0003] According to the search, a Chinese patent publication number CN114953599B published on October 27, 2023, describes a melting and cutting device for producing plastic packaging bags with an edge material recycling structure. It is roughly described as follows: a support frame is fixedly connected to the middle of the upper part of the processing table, a drive mechanism is installed in the middle of the lower part of the processing table, a melting and cutting blade is installed on the drive mechanism, and a cleaning mechanism is installed on one side of the drive mechanism.

[0004] While the aforementioned existing technical solution facilitates the melting and cutting of plastic bag raw materials, the device makes it difficult for the melting and cutting blade to align with the plastic bag, and makes it difficult for personnel to accurately cut the required position, thus reducing work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an edge material recycling device for packaging bag production, thereby solving the problem mentioned in the background technology that it is inconvenient for personnel to accurately cut the required areas, thus reducing work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for recycling edge material in packaging bag production, comprising a mounting plate and a pressure plate. Support legs are fixedly connected to the four corners of the bottom of the mounting plate, and a base plate is fixedly connected to the bottom of each of the four support legs. A mounting frame is fixedly connected to the top of the mounting plate, and a first hydraulic cylinder is mounted on the top of the mounting frame. The output end of the first hydraulic cylinder passes through the mounting frame and is connected to a movable plate. A cutting blade is provided at the bottom of the movable plate. Two through slots are provided at both ends of the mounting frame, and a cutting blade is provided on the pressure plate. The indicator groove cooperates with the cutting blade. Four sliding blocks that are slidably connected to the through groove are fixedly connected to the pressure plate. Both ends of the mounting bracket are rotatably connected to ratchet wheels. One end of the ratchet wheel is fixedly connected to a gear. Both ends of the mounting bracket are rotatably connected to ratchet teeth that cooperate with the ratchet wheels. Each sliding block is connected to a connecting piece through the through groove. A toothed plate that meshes with the gear is fixedly connected to the connecting piece. The mounting plate has a discharge port. The end of the discharge port near the cutting blade has a guide slope. A collection box that cooperates with the discharge port is provided above the base plate.

[0009] By adopting the above technical solution, a stack of plastic bag raw materials is placed under the pressure plate, aligning the cutting position of the plastic bag raw materials with the indicator groove. At this time, the edge material to be cut is located above the guide slope. Pressing the pressure plate moves it, causing the pressure plate to press the plastic bag raw materials. The pressure plate drives the sliding block, connecting parts, and toothed plate to move. The toothed plate drives the gear and ratchet to rotate. After the pressure plate compacts the plastic bag raw materials, the ratchet positions the ratchet to prevent the ratchet from rotating back, thus achieving the purpose of stable positioning of the plastic bag raw materials. At this time, the first hydraulic cylinder is activated to drive the moving plate and cutting blade to move, so that the cutting blade cuts the plastic bag raw materials. At this time, the ratchet is disengaged from the ratchet, and the pressure plate can be lifted away from the plastic bag raw materials. The cut edge material is then guided by the guide slope to slide down to the material outlet, allowing the edge material to fall into the collection box through the material outlet, thus facilitating the alignment of the cutting blade with the plastic bag and improving the working efficiency.

[0010] Optionally, the mounting plate is provided with a clearance groove that cooperates with the cutting blade.

[0011] By adopting the above technical solution, the clearance groove is used to allow the cutting blade to move aside when the cutting blade cuts the plastic bag material, thereby preventing the cutting blade from hitting the mounting plate and being damaged.

[0012] Optionally, the top of the mounting plate is fixedly connected to two side baffles that cooperate with the discharge port, and the top of the mounting plate is fixedly connected to an inclined baffle that cooperates with the discharge port, with the two ends of the inclined baffle connected to the two side baffles respectively.

[0013] By adopting the above technical solution, the side baffle and the inclined baffle work together to protect the cut edge material and prevent it from being disturbed by airflow and flying around.

[0014] Optionally, an anti-slip pad is fixedly connected to the bottom end of the pressure plate.

[0015] By adopting the above technical solution, the anti-slip mat is used to increase the friction between the pressure plate and the plastic bag material, thereby preventing the plastic bag material from slipping off.

[0016] Optionally, two matching limiting grooves are provided on the inner side wall of the mounting bracket, and both ends of the movable plate are fixedly connected with limiting sliders that are slidably connected to the limiting grooves.

[0017] By adopting the above technical solution, the limiting slide and the limiting slider work together to limit the moving plate and the cutting blade, so as to prevent the cutting blade from deflecting and thus improve the cutting accuracy.

[0018] Optionally, a positioning frame that mates with the collection box is fixedly connected to the top of the base plate.

[0019] By adopting the above technical solution, the positioning frame is used to position the collection box, thereby aligning the collection box with the discharge port and the clearance channel, thus avoiding the scattering of edge materials and avoiding increasing the labor intensity of personnel.

[0020] (III) Beneficial Effects

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] This edge material recycling device for packaging bag production places a stack of plastic bag raw materials under a pressure plate, aligning the cutting position of the plastic bag raw materials with the indicator groove. At this time, the edge material to be cut is located above the guide slope. Pressing the pressure plate moves it, causing the pressure plate to press the plastic bag raw materials. The pressure plate drives the sliding block, connecting parts, and toothed plate to move. The toothed plate drives the gear and ratchet to rotate. After the pressure plate compacts the plastic bag raw materials, the ratchet positions the ratchet to prevent the ratchet from rotating back, thus achieving the purpose of stable positioning of the plastic bag raw materials. At this time, the first hydraulic cylinder is activated to drive the moving plate and the cutting blade to move, so that the cutting blade cuts the plastic bag raw materials. Then, the ratchet is disengaged from the ratchet, and the pressure plate can be lifted away from the plastic bag raw materials. The cut edge material is then guided by the guide slope to slide down to the material outlet, allowing the edge material to fall into the collection box through the material outlet. This facilitates the alignment of the cutting blade with the plastic bag, thereby improving the working efficiency. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-3A device for recycling edge material in packaging bag production includes a mounting plate 1 and a pressure plate 2.

The output end of the first hydraulic cylinder 6 passes through the mounting frame 5 and is connected to a movable plate 7. A cutting blade 8 is provided at the bottom of the movable plate 7. Two through slots are provided at both ends of the mounting frame 5, and the pressure plate 2 has a groove that cooperates with the cutting blade 8. The indicator groove 9, the pressure plate 2 has four sliding blocks 10 that are slidably connected to the through groove, the two ends of the mounting bracket 5 are rotatably connected to ratchet 11, one end of the ratchet 11 is fixedly connected to a gear 12, the two ends of the mounting bracket 5 are rotatably connected to ratchet teeth 13 that cooperate with the ratchet 11, the two sliding blocks 10 are connected to the through groove to the connecting piece 14, the connecting piece 14 is fixedly connected to the toothed plate 15 that meshes with the gear 12, the mounting plate 1 has a feeding port, the end of the feeding port near the cutting blade 8 has a guide slope 16, bottom Above plate 4 is a collection box 17 that matches the feeding port. A stack of plastic bag raw materials is placed below pressure plate 2, so that the position of the plastic bag raw materials to be cut is aligned with the indicator groove 9. At this time, the edge material to be cut off is located above the guide slope 16. Pressing pressure plate 2 moves it, so that pressure plate 2 presses the plastic bag raw materials. Pressure plate 2 drives sliding block 10, connecting piece 14 and toothed plate 15 to move. Toothed plate 15 drives gear 12 and ratchet 11 to rotate. After pressure plate 2 compacts the plastic bag raw materials, ratchet 13 positions ratchet 11. To prevent ratchet 11 from rotating and thus achieve stable positioning of the plastic bag material, the first hydraulic cylinder 6 is activated to drive the moving plate 7 and the cutting blade 8 to move, so that the cutting blade 8 cuts the plastic bag material. At this time, the ratchet 13 is disengaged from the ratchet 11, and the pressure plate 2 can be lifted away from the plastic bag material. The cut edge material is then guided by the guide slope 16 to slide down to the feed port, so that the edge material can fall into the collection box 17 through the feed port, which facilitates the alignment of the cutting blade with the plastic bag and improves the working efficiency.

[0031] Reference Figure 3 and Figure 4 The mounting plate 1 is provided with a clearance groove 18 that cooperates with the cutting blade 8. The clearance groove 18 is used to make way for the cutting blade 8 when it cuts the plastic bag material, so as to prevent the blade of the cutting blade 8 from hitting the mounting plate 1 and being damaged.

[0032] Reference Figure 1 The top of the mounting plate 1 is fixedly connected to two side baffles 19 that cooperate with the discharge port. The top of the mounting plate 1 is also fixedly connected to an inclined baffle 20 that cooperates with the discharge port. The two ends of the inclined baffle 20 are respectively connected to the two side baffles 19. The side baffles 19 and the inclined baffle 20 cooperate to protect the cut edge material and prevent the cut edge material from being disturbed by airflow and flying around.

[0033] Reference Figure 4 An anti-slip pad 21 is fixedly connected to the bottom of the pressure plate 2. The anti-slip pad 21 is used to increase the friction between the pressure plate 2 and the plastic bag material, thereby preventing the plastic bag material from slipping off.

[0034] Reference Figure 4 The inner side wall of the mounting bracket 5 has two matching limiting grooves 22. Both ends of the moving plate 7 are fixedly connected to limiting sliders 23 that slide in connection with the limiting grooves 22. The limiting grooves 22 and the limiting sliders 23 cooperate to limit the moving plate 7 and the cutting blade 8, so as to prevent the cutting blade 8 from deflecting, thereby improving the cutting accuracy.

[0035] Reference Figure 1 and Figure 3 The top of the base plate 4 is fixedly connected to a positioning frame 24 that cooperates with the collection box 17. The positioning frame 24 is used to position the collection box 17 so that the collection box 17 is aligned with the discharge port and the clearance channel 18, thereby avoiding the scattering of edge materials and avoiding increasing the labor intensity of personnel.

[0036] In summary, the working principle and process of the edge material recycling device for packaging bag production are as follows: First, a stack of plastic bag raw materials is placed below the pressure plate 2, aligning the cutting position with the indicator groove 9. The edge material to be cut is located above the guide slope 16. The pressure plate 2 is moved, pressing down on the plastic bag raw material. The pressure plate 2 drives the sliding block 10, connecting piece 14, and toothed plate 15 to move. The toothed plate 15 drives the gear 12 and ratchet 11 to rotate. After the pressure plate 2 compacts the plastic bag raw material, the ratchet 13 positions the ratchet 11, preventing it from rotating back, thus achieving stable positioning of the plastic bag raw material. Then, the first hydraulic cylinder 6 is activated, moving the moving plate 7 and the cutting blade 8, causing the cutting blade 8 to cut the plastic bag raw material. At this point, the ratchet 13 is disengaged from the ratchet 11, allowing the pressure plate 2 to be lifted away from the plastic bag raw material. The cut edge material is then guided downwards by the guide slope 16. The feed inlet allows edge material to fall into the collection box 17, facilitating alignment of the cutting blade with the plastic bag and improving work efficiency. The clearance groove 18 allows the cutting blade 8 to be positioned properly during cutting, preventing it from hitting the mounting plate 1 and causing damage. The side baffle 19 works in conjunction with the inclined baffle 20 to protect the cut edge material from airflow disturbance and flying around. The anti-slip pad 21 increases the friction between the pressure plate 2 and the plastic bag material, preventing slippage. The limiting groove 22 works in conjunction with the limiting slider 23 to limit the movement plate 7 and the cutting blade 8, preventing the cutting blade 8 from deviating and improving cutting accuracy. The positioning frame 24 positions the collection box 17, aligning it with the feed inlet and clearance groove 18 to prevent edge material from scattering and to reduce labor intensity.
