Description

Technical Field

[0001] The present invention belongs to the technical field of packaging bag processing, and particularly relates to a packaging bag trimming device with a waste recycling function. Background Art

[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, and is widely used in daily life and industrial production. During the production of packaging bags, the bag body is generally continuous at the beginning, and the edges of the packaging bag are generally heat-sealed by a hot pressing roller. However, in order to ensure the heat-sealing effect, a certain length is generally reserved at the edges of the packaging bag, and a trimming device is subsequently required to cut off the reserved length at the edges.

[0003] For example, in a Chinese invention patent with the publication number CN112429338B and the name of a packaging bag trimming device for food processing, it specifically includes a box body.

[0009] As a further optimized solution of the present invention, the cooling and lubricating mechanism includes a cooling and lubricating box fixedly arranged on the inner side wall of the trimming groove. Valves are fixedly arranged on both sides of the cooling and lubricating box. One end of each of the two valves is fixedly communicated with a disassembly pipe. One side of the disassembly pipe is fixedly communicated with guiding covers located on both sides of the cutting tool. Sponge blocks fitting with both sides of the cutting tool are fixedly arranged on one side of the two guiding covers close to each other. A stirring component cooperating with the turntable is arranged inside the cooling and lubricating box.

[0010] As a further optimized solution of the present invention, the stirring component includes a rotating rod sealingly and rotatably penetrating through the cooling and lubricating box. A plurality of stirring brackets located inside the cooling and lubricating box are fixedly arranged at one end of the rotating rod. A driven gear is fixedly sleeved at the other end of the rotating rod. A toothed ring meshing with the driven gear is fixedly sleeved on the outer side of the turntable.

[0011] As a further optimized solution of the present invention, the waste collection mechanism includes a sliding groove opened on one side of the trimming platform. A sliding plate is slidably connected to one side of the sliding groove. A winding shaft is rotatably connected to one end of the sliding plate. A second servo motor for driving the winding shaft to rotate is fixedly arranged on one side of the sliding plate. An electric telescopic rod for driving the sliding plate to slide is fixedly arranged on one side of the trimming platform.

[0012] As a further optimized solution of the present invention, support frames located on both sides of the trimming groove are fixedly arranged on the upper side and the lower side of the trimming platform. A plurality of installation grooves are opened on both support frames, and ion blowers are fixedly installed inside the plurality of installation grooves.

[0013] As a further optimized solution of the present invention, guide rollers are arranged at both ends of the upper side and the lower side of the trimming platform.

[0016] 2. In the present invention, the coolant can be introduced into the inside of the guiding cover through the disassembly pipe on one side of the cooling and lubricating tank, and then the coolant can be drained into the inside of the sponge block. Since one side of the sponge block is attached to one side of the cutting edge of the cutting knife, on the one hand, the heat on the cutting knife can be dissipated, and on the other hand, the cutting edge of the cutting knife can be lubricated, making the cutting of the cutting knife on the packaging bag smoother, improving the neatness of the cut part of the packaging bag, avoiding burrs, and also cooling the cut part of the packaging bag, preventing the cut part of the packaging bag from sticking due to heat. And during the cutting process, the coolant inside the cooling and lubricating tank can be stirred by the transmission of the gear ring and the driven gear, driving the rotating rod and the stirring bracket to rotate. On the one hand, the temperature of the coolant inside the cooling and lubricating tank can be made more uniform, and on the other hand, the fluidity of the coolant can be improved, facilitating the flow of the coolant into the inside of the sponge block.

[0017] 3. In the present invention, through the ion blower, on the one hand, the static electricity at the cut part of the packaging bag can be eliminated, preventing the cut part of the packaging bag from attracting dust in the air due to static electricity and affecting the cleanliness of the packaging bag. On the other hand, the wind blown by the ion blower can cool the part where the cutting knife cuts the packaging bag, preventing the cutting knife from getting hot during long-term cutting and causing the cut part of the packaging bag to stick. And it can also blow the packaging bag and press it against one side of the cutting knife, making the cutting of the cutting knife smoother. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0021] Embodiment 1: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8As shown in the figure, a bag edge trimming device with waste recycling function includes a trimming platform 1. Two guiding rollers 2 are arranged on the upper side of the trimming platform 1, and the two guiding rollers 2 are respectively arranged at both ends of the trimming platform 1. Two guiding rollers 2 are arranged on the lower side of the trimming platform 1, and the two guiding rollers 2 are respectively arranged at both ends of the trimming platform 1. When in use, two continuous packaging bags (not shown in the figure) are respectively passed through the gaps between the guiding rollers 2 and the trimming platform 1, and the conveying methods of the two packaging bags are opposite, so that two packaging bags can be continuously conveyed at the same time, improving the edge trimming efficiency of the packaging bags. Limit slots 201 are opened at both ends of several guiding rollers 2. The limit slots 201 are arc-shaped and opened on the outer side of the guiding rollers 2. Elastic rings 202 are sleeved on the inner sides of several limit slots 201. The edges of the elastic rings 202 protrude from the arc surfaces of the guiding rollers 2. When in use, on the one hand, the elastic rings 202 on both sides of the guiding rollers 2 can limit the positions of the packaging bags conveyed on one side of the trimming platform 1, ensure the conveying accuracy of the packaging bags, and improve the subsequent edge trimming accuracy. On the other hand, by adjusting the positions of the elastic rings 202, packaging bags with different widths can be limited, improving the application range of the device.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11As shown in the figure, a trimming groove 3 is formed in the middle of the trimming platform 1. The trimming groove 3 penetrates through the trimming platform 1. A trimming mechanism 4 is arranged inside the trimming groove 3. The trimming mechanism 4 includes a turntable 406 rotatably arranged on the inner side wall of the trimming groove 3. A first servo motor 409 is fixedly arranged on one side of the trimming platform 1. The output end of the first servo motor 409 is connected to the turntable 406 through a coupling. There are two turntables 406, and the two turntables 406 are symmetrically arranged on the side walls of the trimming groove 3. A chuck 407 is fixedly arranged on one side of each of the two turntables 406. A rotating shaft 401 is fixedly arranged between the two chucks 407. A through U-shaped groove is formed on one side of each of the two chucks 407, facilitating one end of the rotating shaft 401 to be inserted into the inner side of the chuck 407. A locking bolt 408 fixedly connected to the rotating shaft 401 is arranged on the chuck 407. A plurality of positioning holes 405 are formed at both ends of the rotating shaft 401. The positioning holes 405 penetrate through the rotating shaft 401. A positioning ring 403 is sleeved on the outer side of the rotating shaft 401. A positioning bolt 404 passing through the positioning holes 405 is arranged on the positioning ring 403. Cutting knives 402 are fixedly arranged on the outer sides of the middle parts of the two positioning rings 403. The two sides of the packaging bag can be trimmed simultaneously by the two cutting knives 402, improving the trimming efficiency. The cutting edge of the cutting knife 402 exceeds the two sides of the trimming platform 1. The rotating direction of the cutting knife 402 is opposite to the conveying direction of the two packaging bags, enabling the cutting edge of the cutting knife 402 to cut the edge of the packaging bag faster and improving the smoothness of the cut. Both of the two cutting knives 402 adopt circular blades. The upper and lower sides of the packaging bag can be trimmed simultaneously by the circular blades, improving the trimming efficiency. When trimming packaging bags of different widths, only need to loosen the positioning bolt 404 to release the positioning of the positioning ring 403, then slide the position of the positioning ring 403 on the rotating shaft 401, and then insert the positioning bolt 404 into the positioning hole 405 to fix the positioning ring 403, so that the distance between the two positioning rings 403 can be adjusted, and further the distance between the two cutting knives 402 can be adjusted to meet the trimming of packaging bags of different widths. The turntable 406 is driven to rotate by the first servo motor 409, and then the rotating shaft 401 between the two chucks 407 is driven to rotate, enabling the two cutting knives 402 on the rotating shaft 401 to rotate simultaneously, and further enabling the continuous trimming of the packaging bags on the upper and lower sides of the trimming platform 1. And the cutting knife 402 is opposite to the conveying direction of the packaging bag, which can improve the trimming effect.

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11As shown in the figure, a cooling and lubricating mechanism 6 cooperating with the trimming mechanism 4 is arranged inside the trimming groove 3. The cooling and lubricating mechanism 6 includes a cooling and lubricating box 601 fixedly arranged on the inner side wall of the trimming groove 3. A liquid adding port is arranged on the upper side of the cooling and lubricating box 601, through which it is convenient to add coolant into the interior of the cooling and lubricating box 601. Valves 605 are fixedly arranged on both sides of the cooling and lubricating box 601. One end of each of the two valves 605 is fixedly communicated with a disassembly pipe 602. The flow rate of the cooling oil entering the interior of the disassembly pipe 602 can be controlled through the valves 605. A guiding cover 603 is fixedly communicated with one side of the disassembly pipe 602. The guiding cover 603 is a cavity structure with a hollow interior and an opening on one side, and the openings of the two guiding covers 603 are arranged oppositely. The openings of the two guiding covers 603 are respectively located on both sides of the cutting knife 402 and close to the cutting knife 402. A sponge block 604 is fixedly arranged on the side where the two guiding covers 603 are close to each other. The coolant inside the guiding cover 603 can be absorbed through the sponge block 604, and the leakage of the coolant inside the guiding cover 603 can also be prevented through the sponge block 604. The two sponge blocks 604 are squeezed and attached to both sides of the cutting knife 402. During use, when the cutting knife 402 rotates for trimming, by opening the valves 605, the coolant inside the cooling and lubricating box 601 can flow into the interior of the disassembly pipe 602, and then the coolant enters the interior of the guiding cover 603, and the coolant is drained into the interior of the sponge block 604. When the cutting knife 402 rotates through the sponge block 604, on the one hand, the heat on the cutting knife 402 can be conducted into the interior of the coolant, so that the cutting knife 402 is cooled, avoiding overheating on the surface of the continuously cutting cutting knife 402 and causing adhesion at the cut part of the packaging bag. On the other hand, the coolant can also be coated on the surface and the cutting edge part of the cutting knife 402, so that the cutting edge of the cutting knife 402 is lubricated, making the cutting knife 402 smoother during the process of cutting the packaging bag, improving the neatness of the cut part of the packaging bag and avoiding the appearance of burrs.

[0024] As Figure 2 , Figure 5 , Figure 7 , Figure 10As shown in the figure, a rotating rod 606 penetrates through one side of the cooling and lubricating tank 601 in a sealed manner. One end of the rotating rod 606 is fixedly provided with a number of stirring brackets 607. The number of stirring brackets 607 is located inside the cooling and lubricating tank 601. The other end of the rotating rod 606 is fixedly sleeved with a driven gear 608. The outer side of the turntable 406 is fixedly sleeved with a toothed ring 609. The toothed ring 609 meshes with the driven gear 608. During the cutting process of the packaging bag, when the turntable 406 rotates, it will drive the toothed ring 609 on the outer side of the turntable 406 to rotate synchronously, and then drive the driven gear 608 to rotate, driving the rotating rod 606 to rotate, so that a number of stirring brackets 607 at the other end of the rotating rod 606 rotate inside the cooling and lubricating tank 601, which can stir the coolant inside the cooling and lubricating tank 601. On the one hand, it can make the temperature of the coolant inside the cooling and lubricating tank more uniform. On the other hand, it can improve the fluidity of the coolant, facilitating the coolant to flow into the sponge block 604.

[0025] As Figure 1 , Figure 2 , Figure 7 As shown in the figure, two waste collection mechanisms 5 are arranged on the upper side of the trimming platform 1, and two waste collection mechanisms 5 are arranged on the lower side of the trimming platform 1. The two waste collection mechanisms 5 on the upper side and the two waste collection mechanisms 5 on the lower side are centrosymmetric about the center of the rotating shaft 401. The waste on both sides of the packaging bag can be collected simultaneously through the waste collection mechanisms 5 on both sides. The waste collection mechanism 5 includes a chute 501 opened on one side of the trimming platform 1. One side of the chute 501 is slidably connected with a sliding plate 502. One end of the sliding plate 502 is rotatably connected with a winding shaft 503. During use, a waste winding roller (not shown in the figure) is fixedly sleeved on the winding shaft 503, which is convenient for winding and recycling the trimmed waste. A second servo motor 504 for driving the winding shaft 503 to rotate is fixedly arranged on one side of the sliding plate 502. An electric telescopic rod 505 for driving the sliding plate 502 to slide is fixedly arranged on one side of the trimming platform 1. During use, by driving the winding shaft 503 to rotate through the second servo motor 504, the waste winding roller on the winding shaft 503 can be driven to rotate, so that during the trimming process of the packaging bag, the edge waste can be wound onto the waste winding roller, which is convenient for storing and recycling the waste. And by driving the sliding plate 502 to slide through the electric telescopic rod 505, the position of the winding shaft 503 can be adjusted, so that the surface of the waste winding roller can evenly wind the edge waste of the packaging bag, improving the storage efficiency.

[0026] Embodiment 2: Further improvement based on Embodiment 1 lies in that, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, support frames 7 are fixedly arranged on both the upper and lower sides of the trimming platform 1 and are located on both sides of the trimming groove 3. On one side of the two support frames 7, the support plates are each provided with two mounting grooves 701, and the two mounting grooves 701 are respectively located on one side of the cutting knife 402. Inside several mounting grooves 701, ion blowers 8 are fixedly installed by screws. During use, ion airflows are generated by the ion blowers 8 and blown to the cut part of the packaging bag. On the one hand, the static electricity at the cut part of the packaging bag can be eliminated, preventing the cut part of the packaging bag from attracting dust in the air due to static electricity and affecting the cleanliness of the packaging bag. On the other hand, the airflows blown by the ion blowers 8 can cool the part of the cutting knife 402 where the packaging bag is cut, preventing the cutting knife 402 from heating up during long-term cutting, causing the cut part of the packaging bag to stick. Moreover, the airflows can also blow the packaging bag against one side of the cutting knife 402, enabling the cutting knife 402 to cut the packaging bag more smoothly, preventing the packaging bag from wrinkling at the cutting part and affecting the cutting effect. Additionally, the coolant coated on the surface of the cutting knife 402 can be cooled again, improving the cooling effect of the cutting knife 402.

[0027] It should be noted that when using this packaging bag trimming device with a waste recycling function, first pass one packaging bag through the upper side of the trimming platform 1 and under the two guide rollers 2 on the upper side of the trimming platform 1, and pass the other packaging bag through the lower side of the trimming platform 1 and over the two guide rollers 2 on the lower side of the trimming platform 1. The packaging bag on the upper side of the trimming platform 1 moves from left to right in Figure 1 's perspective, and the packaging bag on the lower side of the trimming platform 1 moves from right to left in Figure 1 's perspective. Then, drive the turntable 406 to rotate through the first servo motor 409, and then drive the rotating shaft 401 between the two chucks 407 to rotate, so that the two cutting knives 402 on the rotating shaft 401 can rotate simultaneously, thereby continuously trimming the packaging bags on the upper and lower sides of the trimming platform 1. And the cutting knives 402 are in the opposite direction to the conveying direction of the packaging bags, that is, in Figure 1The perspective cutting knife 402 rotates counterclockwise. Before the cutting process, the valve 605 is opened, allowing the coolant inside the cooling and lubricating tank 601 to flow into the inside of the disassembly pipe 602. Then, the coolant enters the inside of the guide cover 603 and is drained into the inside of the sponge block 604. When the cutting knife 402 rotates through the sponge block 604, since the sponge block 604 is pressed against both sides of the cutting knife 402, the coolant inside the sponge block 604 is coated on both side walls of the cutting knife 402, cooling the cutting knife 402 and lubricating the cutting edge of the cutting knife 402. At the same time, when the turntable 406 rotates, it drives the gear ring 609 outside the turntable 406 to rotate synchronously, then drives the driven gear 608 to rotate, drives the rotating rod 606 to rotate, and makes several stirring brackets 607 at the other end of the rotating rod 606 rotate inside the cooling and lubricating tank 601, so that the coolant inside the cooling and lubricating tank 601 can be stirred. During the cutting process, an ion air flow is generated by the ion blower 8 and blown to the cut part of the packaging bag. On the one hand, it can eliminate the static electricity at the cut part of the packaging bag. On the other hand, through the air flow blown by the ion blower 8, the cutting knife 402 can be cooled at the part where it cuts the packaging bag, and the air flow can also blow the packaging bag against one side of the cutting knife 402, making the cutting knife 402 cut the packaging bag more smoothly. During the cutting of the packaging bag, the second servo motor 504 drives the take-up reel 503 to rotate, which drives the waste take-up reel on the take-up reel 503 to rotate, winding the edge waste onto the waste take-up reel for waste recycling.

[0028] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
