Description

Technical Field

[0001] This utility model relates to a paper bag collection device, specifically a paper bag collection device for a paper bag production line, and belongs to the technical field of paper bag production equipment. Background Technology

[0002] Paper bag production lines can produce paper bags efficiently and automatically, significantly improving production efficiency and product quality. Through a series of automated and intelligent processes, paper bag production lines transform paper into complete paper bags. At the end of the paper bag production line, a paper bag collection device is set up to collect the formed paper bags.

[0003] However, when collecting larger paper bags, in order to prevent the paper bags from shifting too much during the fall, the height difference between the end of the collecting device and the end of the paper bag conveying device must not be too large. Therefore, when collecting a small number of paper bags each time, the staff needs to remove the paper bags from the collecting device, which wastes a lot of physical strength and results in poor operation convenience. Utility Model Content

[0004] The purpose of this invention is to provide a paper bag collecting device for a paper bag production line to solve the above problems. This device can collect a large number of paper bags at once, thereby avoiding the need for workers to frequently pick up paper bags, effectively saving physical strength and improving the convenience of operation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a paper bag collecting device for a paper bag production line, comprising a support frame, a bag receiving structure on the support frame, the bag receiving structure including a support base, a support base fixedly connected to the support frame, two first motors mounted on the support base, four synchronous pulleys rotatably connected to the support frame, two synchronous pulleys on the same side of the support base having the same synchronous belt wound around them, the output shaft of the first motor being fixedly connected to the adjacent synchronous pulley, two connecting seats fixedly connected to the synchronous belt, a locking block slidably connected inside the connecting seat, and a first spring fixedly connected between the locking block and the connecting seat. Between two opposing locking blocks, there is a placement tray, with the other placement tray at the top of the first placement tray. Two sliders are fixedly connected to both sides of the placement tray, and the sliders are slidably connected to the support base. The two sliders on both sides of the first placement tray engage with the two locking blocks respectively, and the two sliders on both sides of the other placement tray abut against the blocking structure. Two electric push rods are installed inside the support frame, and the ends of the electric push rods are fixedly connected to the blocks. The blocks engage with the support frame. The support frame has two first openings and two second openings. The support frame also has a conveying structure.

[0006] Preferably, the top of the slider has an inclined cut surface, and the cross-section of one end of the card block has a trapezoidal structure.

[0007] Preferably, the cross-section of the top of the abutment is trapezoidal, and the abutment is located directly below the slider.

[0008] Preferably, the height of the first opening is equal to the height of the second opening, and the height of the first opening is greater than the height of the slider cross-section.

[0009] Preferably, the blocking structure includes a stop block and a second spring. Two stop blocks are slidably connected on the support base. The top of the stop block abuts against the adjacent slider. The second spring abuts against the stop block and the support base.

[0010] Preferably, the cross-section of the stop block at one end outside the support base is trapezoidal, and the cross-section of the other end of the stop block is T-shaped.

[0011] Preferably, the conveying structure includes a connecting frame and a second motor. The connecting frame is fixedly connected to the support frame, the second motor is mounted on the connecting frame, multiple rotating shafts are rotatably connected to the connecting frame, multiple connecting wheels are fixedly connected to the rotating shafts, and the same conveyor belt is wound around the multiple connecting wheels in the same column on different rotating shafts. The output shaft of the second motor is fixedly connected to one of the rotating shafts.

[0012] Preferably, the plurality of rotating shafts are linearly and equidistantly distributed, and the plurality of connecting wheels located on the same rotating shaft are linearly and equidistantly distributed.

[0013] Preferably, a support plate is fixedly connected to the support frame, and a camera is mounted on the support plate.

[0014] Preferably, a baffle is fixedly connected to the support base, and the baffle is perpendicular to the placement tray.

[0015] The beneficial effects of this utility model are as follows: During use, paper bags can be conveyed by a conveying device. When the paper bags are conveyed to the end of the conveying structure, they will fall into the interior of one of the placement trays due to inertia. When a certain amount of paper bags are collected in one of the placement trays, two first motors can be started simultaneously. The output shafts of the first motors rotate, driving one of the synchronous pulleys to rotate. The rotation of the synchronous pulley causes the synchronous belt to move, thus causing both synchronous belts to move simultaneously. The movement of the synchronous belts drives two connecting seats to move, which in turn drives the locking blocks to move. The locking blocks then drive the sliders to move, which in turn drives one of the placement trays to move. When one of the placement trays has moved a certain distance, the output shaft of the first motor stops rotating. At this point, the topmost collected paper bag will be located at the original position of one of the placement trays. The collection of paper bags continues, and the above operation is repeated after a certain amount is collected. Therefore, a larger number of paper bags can be collected at once, avoiding the need for workers to frequently remove paper bags from the placement trays, thus saving physical labor and improving the convenience of operation. When one of the placement trays is about to approach the locking block, the output shaft of the first motor can be started to rotate again, causing the two sliders to continue moving. During the movement, the slider engages with the stop block. As the slider continues to move, the top of the stop block contacts the stop block, causing it to move inward toward the connecting seat. The first spring contracts, and the bottom of the placement plate contacts the support frame. One connecting seat continues to move, while the other moves toward the other placement plate. During the movement of the other connecting seat, its internal stop block contacts the inclined surface at the top of the slider. The stop block then moves inward toward the connecting seat and engages with the slider. The movement of the stop block drives the slider to move, and the movement of the two sliders drives the other placement plate to move. When the other placement tray is in the initial position of one of the placement trays, the output shaft of the first motor stops rotating, and then the paper bags can be collected. At the same time, the paper bags collected on one of the placement trays can be removed. After all the paper bags are removed, two electric push rods can be activated at the same time. The extension of the electric push rods will cause the stop block and the slider to disengage. Then, one of the placement trays is taken out from the second opening and then placed into the inside of the support base from the first opening, so that the two sliders on both sides abut against the stop structure. This cycle is repeated to achieve automatic collection of paper bags without stopping the machine, thereby improving production efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 and Figure 3As shown, a paper bag collecting device for a paper bag production line includes a support frame 1. A bag receiving structure 2 is provided on the support frame 1. The bag receiving structure 2 includes a support base 201. The support base 201 is fixedly connected to the support frame 1. Two first motors 202 are mounted on the support base 201. Four synchronous pulleys 203 are rotatably connected to the support frame 1. A common synchronous belt 204 is wound around two synchronous pulleys 203 located on the same side of the support base 201. The output shaft of the first motor 202 is fixedly connected to the adjacent synchronous pulley 203. Two connecting seats 205 are fixedly connected to the synchronous belt 204. A locking block 206 is slidably connected inside the connecting seat 205. A first spring 207 is fixedly connected between the locking block 206 and the connecting seat 205. A placement tray 209 is provided between two opposing locking blocks 206. The top of one placement tray 209 is provided with another placement tray 209. Two sliders 208 are fixedly connected to both sides of the placement tray 209. The top of each slider 208 has an inclined cut surface. The sliders 208 are slidably connected to the support base 201. The two sliders 208 on both sides of one of the placement trays 209 are engaged with two locking blocks 206 respectively. The two sliders 208 on both sides of the other placement tray 209 abut against the blocking structure 3. Two electric push rods 211 are installed inside the support frame 1. The end of each electric push rod 211 is fixedly connected to a stop block 210. The stop block 210 is located directly below the sliders 208 and is engaged with the support frame 1. The support frame 1 has two first openings 212 and two second openings 213. The height of the first opening 212 is equal to the height of the second opening 213. The height of the first opening 212 is greater than the height of the slider 208 cross section. The support frame 1 has a conveying structure 4.

[0027] As a technical optimization of this utility model, the blocking structure 3 includes a stop block 301 and a second spring 302. Two stop blocks 301 are slidably connected on the support base 201. The top of the stop block 301 abuts against the adjacent slider 208, so the stop block 301 can block the slider 208 and prevent the placement plate 209 from shifting under the action of gravity. The stop block 301 and the support base 201 are abutted by the second spring 302. The cross-section of the stop block 301 at the outer end of the support base 201 is trapezoidal. Therefore, when the slider 208 applies a large force to the stop block 301, the stop block 301 can overcome the elastic force of the second spring 302 and move towards the inside of the support base 201. The cross-section of the other end of the stop block 301 is T-shaped.

[0028] As a technical optimization of this utility model, the conveying structure 4 includes a connecting frame 401 and a second motor 402. The connecting frame 401 is fixedly connected to the support frame 1, and the second motor 402 is installed on the connecting frame 401. Multiple rotating shafts 403 are rotatably connected to the connecting frame 401. The multiple rotating shafts 403 are linearly and equidistantly distributed. Multiple connecting wheels 404 are fixedly connected to the rotating shafts 403. The multiple connecting wheels 404 located on the same rotating shaft 403 are linearly and equidistantly distributed. The same conveyor belt 405 is wound on the multiple connecting wheels 404 in the same column located on different rotating shafts 403. The output shaft of the second motor 402 is fixedly connected to one of the rotating shafts 403. Therefore, when the output shaft of the second motor 402 rotates, multiple conveyor belts 405 can move simultaneously, thereby realizing the conveying of paper bags.

[0029] As a technical optimization of this utility model, a support plate 5 is fixedly connected to the support frame 1, so as to support the camera 6. The camera 6 is installed on the support plate 5, so that the camera 6 can count, and the collected number is fed back to the control system to control the first motor 202.

[0030] As a technical optimization of this utility model, a baffle 7 is fixedly connected to the support base 201, so that it can block the paper bag during the falling process and prevent the paper bag from falling off the placement tray 209.

[0031] In use, this invention utilizes a second motor 402. The output shaft of the second motor 402 rotates, causing one of the rotating shafts 403 to rotate. The rotation of the rotating shaft 403 causes multiple connecting wheels 404 to rotate, which in turn causes multiple conveyor belts 405 to move. Therefore, paper bags entering one end of the paper bag production line are conveyed to the other end of the conveyor belts 405 under the action of the multiple conveyor belts 405 and fall into one of the placement trays 209 due to inertia. A baffle 7 prevents the paper bags from falling to the ground from inside the placement tray 209. Once a certain amount of paper bags are collected inside one of the placement trays 209, they can be... Simultaneously, two first motors 202 are activated. The output shafts of the first motors 202 rotate, driving one of the synchronous pulleys 203 to rotate. The rotation of the synchronous pulley 203 causes the synchronous belt 204 to move, thus causing both synchronous belts 204 to move simultaneously. The movement of the synchronous belts 204 drives the two connecting seats 205 to move, which in turn drives the locking block 206 to move. The movement of the locking block 206 drives the slider 208 to move, which in turn drives one of the placement trays 209 to move. After one of the placement trays 209 has moved a certain distance, the output shafts of the first motors 202 stop rotating. At this point, the topmost collected paper bag will be located at the original position of one of the placement trays 209, and the collection of paper bags will continue. Once a certain amount is collected, the above operation is repeated, thus collecting a larger number of paper bags at once. This avoids the need for staff to frequently remove the paper bags from the placement tray 209, saving physical effort and improving operational convenience. When one of the placement trays 209 is about to approach the abutment block 210, the output shaft of the first motor 202 continues to rotate, causing the two sliders 208 to continue moving. During the movement, the sliders 208 engage with the abutment block 210. As the sliders 208 continue to move, the top of the abutment block 210 contacts the locking block 206, causing it to move towards the interior of the connecting seat 205. The first spring 207 contracts, and then the bottom of the placement tray 209 contacts the support frame 1. Then one of the connecting trays... The connecting seat 205 continues to move, while the other connecting seat 205 moves toward the other placement plate 209. During the movement of the other connecting seat 205, the internal locking block 206 abuts against the inclined surface at the top of the slider 208. Then, the locking block 206 moves toward the interior of the connecting seat 205 and engages with the slider 208. The movement of the locking block 206 drives the slider 208 to move. During the movement of the slider 208, it abuts against the stop block 301 and moves toward the interior of the support seat 201. The second spring 302 contracts. The movement of the two sliders 208 drives the other placement plate 209 to move. When the other placement plate 209 is in the initial position of one of the placement plates 209, the output shaft of the first motor 202 stops rotating.Then, paper bags can be collected. Simultaneously, paper bags collected on one of the placement trays 209 can be removed. Once all are removed, two electric push rods 211 are activated. The extension of the electric push rods 211 causes the stop block 210 and slider 208 to disengage. One of the placement trays 209 is then removed from the second opening 213 and placed into the support base 201 through the first opening 212, causing the two sliders 208 on both sides to abut against the stop block 301. This cycle repeats, achieving automatic paper bag collection without stopping the machine, thus improving production efficiency. During collection, the camera 6 counts the collected bags, and the number collected is fed back to the control system to control the first motor 202.
