Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically to an automatic bagging machine for motorcycle helmet rainproof film. Background Technology

[0002] Motorcycle helmet rainproof films are a common fast-moving consumer good, and their market demand continues to grow. However, the crucial step from production to market—packaging—currently relies mainly on manual labor. This manual packaging method not only leads to high labor costs but also becomes a bottleneck restricting the improvement of overall production efficiency. Due to the limited speed of manual operation and susceptibility to fatigue, it is difficult to consistently guarantee the high capacity and consistent packaging quality required for mass production.

[0003] While automated packaging solutions exist for fast-moving consumer goods (FMCG), mainstream technologies (such as batch film covering, heat sealing, and cutting) are significantly inadequate for the "bagging" requirements of motorcycle helmet rainproof films. These devices are typically complex and bulky, requiring substantial production space, and their high cost significantly hinders widespread adoption. More importantly, the equipment and technology themselves are not perfectly suited to the specific packaging model of precisely placing individual rainproof films into pre-made bags, making them cumbersome and inefficient.

[0004] Therefore, existing packaging solutions, whether high-cost and inefficient manual methods or large-scale equipment that, while automated, is space-consuming, expensive, and technologically incompatible, have failed to effectively address the practical pain points of motorcycle helmet rainproof film packaging. The market urgently needs specialized equipment that can automatically complete the bagging of motorcycle helmet rainproof film while possessing the advantages of miniaturization and low cost, in order to overcome production capacity bottlenecks, reduce production costs, and adapt to space-constrained production environments.

The second rodless cylinder slider at the output end of the second rodless cylinder is connected to the connection end of the second and third rod cylinder via a second two-cylinder connecting plate. The output end of the second and third rod cylinder is connected to the input end of the sheet suction cup assembly. The bagging unit includes a first push-in guide rail, a pusher frame, a second push-in guide rail, and a third rodless cylinder. The first and second push-in guide rails are fixedly connected to the working platform, and the third rodless cylinder is fixedly connected to the frame through a bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs linear guide slide modules in conjunction with stepper motors to lift and stack materials in both the bag storage unit and the sheet storage unit. This design ensures that the packaging bags and rainproof films can be precisely lifted layer by layer, always maintaining them in the optimal position for suction cup retrieval, avoiding the tedious manual adjustments required at any time. Compared to existing large-volume equipment, this device achieves precise positioning through a modular, compact structure, not only reducing the floor space required but also improving the stability of the storage and retrieval process, and reducing the risk of material jamming and displacement.

[0014] This invention employs a combination of rodless and three-bar cylinders to drive the suction cup assembly in both the bag and sheet transport units. This design enables bidirectional vertical and horizontal movement, ensuring the suction cups accurately pick up and place materials at the appropriate positions. The negative pressure suction of the suction cups avoids damage to the rainproof film caused by mechanical clamping, while the four-point or two-point suction cup structure prevents material skewing or curling, significantly improving the reliability of the bagging process.

[0015] This invention's bagging unit employs a pusher frame and a guide rail to stably push the rainproof film into the packaging bag. The pusher frame's C-shaped structure has a groove at its front end to firmly hold the film and prevent slippage during the pushing process; the stepped guide rail design further prevents film deviation. This ingenious guiding and pushing mechanism allows individual films to smoothly and accurately enter the pre-opened bag, achieving a high success rate of automatic single-film bagging and significantly improving packaging quality and production efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. like Figures 1-12 As shown, an automatic bagging machine for motorcycle helmet rainproof film includes six units: a bag storage unit, a bag transport unit, a bag opening unit, a sheet storage unit, a sheet transport unit, and a bagging unit.

[0019] In the bag storage unit, the lower bag support plate 102 is bolted to the frame 101. The first linear guide slide module 105 is bolted to the frame 101 and placed at the center line of the lower bag support plate 102. The first stepper motor 103 is connected to the first coupling 104 and then connected to the screw in the first linear guide slide module 105 and fixed to the module. The upper bag support plate 110 is screwed to the first guide slider 112. The bag positioning side plate 111 is bolted to the lower bag support plate 102 and is arranged around the packaging bags 107 to ensure the positioning of the packaging bag stack formed by the packaging bags 107. The transmitting end 108 of the first photoelectric sensor is installed on the sensor bracket 109, and the receiving end 106 of the first photoelectric sensor is installed on the frame 101. The two are respectively arranged on the left and right sides of the bag storage unit to generate an optical path above the packaging bag stack, ensuring that the height of the upper surface of the bag stack is controllable.

[0020] When the bag storage unit is working, the first stepper motor 103 rotates, which drives the screw to rotate through the first coupling 104, causing the first guide rail slider 112 to rise, which in turn drives the bag support plate 110 to rise, causing the packaging bag stack to rise. Once the upper surface of the packaging bag stack rises to the point of blocking the optical path formed by the transmitting end 108 and the receiving end 106 of the first photoelectric sensor, the stepper motor is controlled to stop. The optical path is connected again after the packaging bag at the top of the packaging bag stack is sent away by the bag transport unit, and the first stepper motor 103 moves, and so on.

[0021] In the bag transport unit, the first rodless cylinder 205 is bolted to the frame 101 and suspended above the storage unit. The first rodless cylinder slider 203 on the first rodless cylinder 205 is screwed to the first three-bar cylinder 202 through the first two-cylinder connecting plate 204. The first three-bar cylinder 202 is screwed to the first suction cup plate 206. Four bag suction cups are fixed on the first suction cup plate 206, namely the first bag suction cup 201, the second bag suction cup 207, the third bag suction cup 301 and the fourth bag suction cup 302.

[0022] When the bag transport unit is working, when the light path generated by the transmitter 108 and receiver 106 of the first photoelectric sensor is blocked, the first rodless cylinder 205 performs position judgment, causing the first rodless cylinder slider 203 to move to one side of the storage unit. Then, the first three-bar cylinder 202 is de-aired, causing it to release and the first suction cup plate 206 to fall. At this time, the four bag suction cups, namely the first bag suction cup 201, the second bag suction cup 207, the third bag suction cup 301, and the fourth bag suction cup 302, fall above the bag. After a short delay, the four bag suction cups are ventilated, generating negative pressure to adsorb the bag. After a short delay, the first three-bar cylinder 202 is ventilated, the cylinder retracts, and the adsorbed bag leaves the top of the bag pile. After a short delay, the first rodless cylinder 205 is ventilated, causing the first rodless cylinder slider 203 to move the bag to the other side.

[0023] In the bag opening unit, the work platform 303 is laid flat and bolted to the frame 101. The second suction cup plate 306 is bolted to the frame 101, and the suction cup heads of the two fifth bag suction cups 304 and the sixth bag suction cup 305 fixed on the second suction cup plate are slightly higher than the upper surface of the work platform 303.

[0024] When the bag opening unit is working, when the position of the first rodless cylinder 205 determines that the slider 203 of the first rodless cylinder has moved to one side of the working platform, the first three-bar cylinder 202 is de-aired, causing the first suction cup plate 206 to fall. After a short delay, the first bag suction cup 201 and the second bag suction cup 207 are de-aired, while the third bag suction cup 301 and the fourth bag suction cup 302 remain ventilated, and the fifth bag suction cup 304 and the sixth bag suction cup 305 are ventilated. This allows the four bag suction cups (the third bag suction cup 301, the fourth bag suction cup 302, the fifth bag suction cup 304, and the sixth bag suction cup 305) to suck up the bag opening at the top and bottom corners. After a short delay, the first three-bar cylinder 202 is ventilated, pulling open the bag opening to complete the bag opening.

[0025] In the chip storage unit, the chip support lower plate 401 is bolted to the frame 101. The second linear guide slide module 413 is bolted to the frame 101 and positioned at the center line of the chip support lower plate 401, with its top flush with the upper surface of the frame. The second stepper motor 415 is connected to the second coupling 414 and then to the screw in the second linear guide slide module 413 and fixed to the module. The chip support upper plate 402 is screwed to the second guide slide 417. The chip positioning column 403 is screwed to the column positioning piece 416, which is bolted to the chip support lower plate 401 and arranged around the rainproof film 507 to ensure the positioning of the rainproof film stack formed by the stacked rainproof films 507. The transmitting end 404 and the receiving end B412 of the second photoelectric sensor, respectively arranged on the left and right sides of the chip storage unit, generate an optical path above the rainproof film, ensuring that the height of the upper surface of the rainproof film stack is controllable. When the chip storage unit is working, the second stepper motor 415 rotates, which drives the screw in the second linear guide slide module 413 to rotate through the second coupling 414, causing the second guide slide block 417 to rise, which in turn drives the chip support plate 402 to rise, causing the rainproof film stack to rise. Once the upper surface of the rainproof film stack rises to block the light path generated by the transmitting end 404 of the second photoelectric sensor and the receiving end B412 of the photoelectric sensor, the second stepper motor 415 is controlled to stop until the rainproof film at the top of the rainproof film stack is sent away by the chip transport unit, after which the light path is connected, and the second stepper motor 415 moves again, and so on.

[0026] In the sheet transport unit, the second rodless cylinder 410 is bolted to the frame 101 and suspended above the sheet storage unit. The second rodless cylinder slider 409 on the second rodless cylinder 410 is screwed to the second three-bar cylinder 411 through the second two-cylinder connecting plate 408. The second three-bar cylinder 411 is screwed to the second suction cup plate 406. Two sheet suction cups are fixed on the second suction cup plate 406, namely the first sheet suction cup 405 and the second suction cup 407.

[0027] When the sheet transport unit is working, when the light path generated by the transmitting end 404 and the receiving end B412 of the second photoelectric sensor is blocked, the second rodless cylinder 410 performs position judgment, causing the second rodless cylinder slider 409 to move to one side of the sheet storage unit. Then, the second and third rod cylinders 411 are de-aired, causing the second and third rod cylinders 411 to release, causing the second suction cup plate 406 to fall. At this time, the first sheet suction cup 405 and the second sheet suction cup 407 fall above the rainproof film stack. After a short delay, the two sheet suction cups are ventilated, generating negative pressure to adsorb the rainproof film. After a short delay, the second and third rod cylinders 411 are ventilated and retract, causing the adsorbed rainproof film to leave the top of the rainproof film stack. After a short delay, the second rodless cylinder 410 is ventilated, causing the second rodless cylinder slider 409 to move the rainproof film to the other side.

[0028] In the bagging unit, the first push-in guide rail 501 and the second push-in guide rail 502 are bolted to the working platform 303. The two push-in guide rails have stepped surfaces to ensure that the rainproof film 507 does not slip during the pushing process. The third rodless cylinder 603 is placed flat and bolted to the frame 101. Its third rodless cylinder slider 602 is screwed to the pusher frame 601. The pusher frame 601 is a C-shaped part with a groove at its front end to frame the film, ensuring that the rainproof film does not slip during the pushing process. The upper surface of the groove opening at the front end of the pusher frame is 2 to 3 mm higher than the upper surfaces of the two push-in guide rails. When the bagging unit is working, when both the first rodless cylinder 205 and the second rodless cylinder 410 detect that their respective rodless cylinder sliders are on one side of the film loading stroke, after a short delay, the third rodless cylinder… When cylinder 603 is ventilated, the third rodless cylinder slider 602 drives the pusher frame 601 to move. The groove at the front of the pusher frame 601 catches the sheet as it moves forward, pushing the rainproof film 507 into the packaging bag 107. When the third rodless cylinder 603 detects that the third rodless cylinder slider 602 is on the other side, the third rodless cylinder 603 immediately ventilates to return the pusher frame to its original position. After a short delay, the third bag suction cup, the fourth bag suction cup, the fifth bag suction cup, and the sixth bag suction cup are de-ventilated, allowing the packaged rainproof film to fall naturally onto the work platform 303. At the same time, the first rodless cylinder and the second rodless cylinder ventilate to move the first three-bar cylinder and the second three-bar cylinder to the storage unit side. When the pusher frame returns to its original position, the conveyor belt 604 starts and removes the packaged rainproof film, completing one packaging cycle.

[0029] The overall workflow of this utility model is as follows: First, the bag storage unit, through the bag support lower plate 102, bag support upper plate 110, bag positioning side plate, and first linear guide slide module 105, works in conjunction with the first stepper motor 103 to raise the stack of packaging bags 107 layer by layer. The height is monitored in real time by the first photoelectric sensor to ensure that the top layer of bags is in a retrievable position. The first rodless cylinder 205 of the bag transport unit drives the first three-bar cylinder 202 and the bag suction cup assembly to pick up a single packaging bag and send it to the working platform 303. Subsequently, the fifth bag suction cup 304 and the sixth bag suction cup 305 on the second suction cup plate 306, together with the third bag suction cup 301 and the fourth bag suction cup 302 above, open the bag opening to form a bagging channel.

[0030] Meanwhile, the sheet storage unit, driven by the sheet support lower plate 401, sheet support upper plate 402, sheet positioning column, and second linear guide slide module 413, operates under the influence of the second stepper motor 415, causing the rainproof film sheets 507 to gradually rise. A second photoelectric sensor detects the height, ensuring the top sheet is in the picking position. The sheet transport unit, via the second rodless cylinder 410 and the second three-bar cylinder 411, lowers the sheet suction cup assembly above the film, adsorbing individual rainproof films and transporting them to the top of the push-in guide rail. At this point, the sheet suction cup assembly releases the rainproof film, allowing it to fall naturally and accurately onto the surface of the push-in guide rail.

[0031] Once the rainproof film 507 lands on the push-in guide rail and the third bag suction cup 301 and the fourth bag suction cup 302 have completed the bag opening action, the third rodless cylinder 603, since the push-in guide rail and the packaging bag 107 are on the same straight line, immediately activates, driving the pusher frame 601 forward along the push-in guide rail. The C-shaped groove structure at the front end of the pusher frame frames the film and pushes it stably along the guide rail, allowing the rainproof film to smoothly enter the opened packaging bag. After bagging is complete, the pusher frame resets, the bag suction cup releases negative pressure, and the packaged film falls onto the work platform 303 and is conveyed out by the conveyor belt 604, thus completing one full bagging cycle.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and design concept of this utility model, should be covered within the scope of protection of the claims of this utility model.
