Description
Technical Field
[0001] The utility model relates to the technical field of packaging bag sealing machines, in particular to a packaging bag sealing machine. Background Art
[0002] A sealing machine is a machine for sealing containers filled with products. After the products are loaded into the packaging containers, in order to seal and preserve the products, maintain the product quality, and avoid product loss, it is necessary to seal the containers. When sealing plastic bags, a chain plate sealing machine is often used for sealing. The packaging bag filled with products is placed on the chain plate of the chain plate sealing machine and conveyed for sealing. Under the action of the heating plate, the surface of the chain plate conveyor belt is heated, and then the plastic packaging bag is melted and sealed, thus achieving the sealing effect.
[0003] The inventor found during the daily use of the sealing machine that when sealing through the chain plate conveyor, due to the fixed size of the roller, the distance between the conveyors is equal, which makes it impossible to seal some relatively thick plastic packaging bags, resulting in the inability of the chain plate sealing machine to adjust the distance between the two conveyor belts, thus causing an impact. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a packaging bag sealing machine.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A packaging bag sealing machine includes an operating table. A rectangular plate is fixedly connected to the side of the operating table. A motor is fixedly connected to the side of the rectangular plate. The output end of the motor is fixedly connected to a roller. A chain plate conveyor belt is rotatably connected to the surface of the roller. A heating plate is fixedly connected to the side of the rectangular plate. A heating machine is fixedly connected to the side of the rectangular plate. One side of the heating plate is in contact with one side of the chain plate conveyor belt. An adjusting device is arranged on the surface of the roller. A cleaning device is arranged on the side of the rectangular plate. The adjusting device includes a circular groove opened inside the roller. A sliding rod is slidably connected inside the circular groove. One end of the sliding rod is fixedly connected to an arc-shaped plate. The other end of the sliding rod is fixedly connected to a trapezoidal block. A screw rod is rotatably connected inside the circular groove. One end of the screw rod is rotatably connected to a conical block.
[0006] The effects achieved by the above components are as follows: Under the action of the conical block and the trapezoidal block, the arc-shaped plate can be expanded or contracted on the surface of the rotating roller, thereby achieving the function of adjusting the diameter of the rotating roller. When it is necessary to seal the packaging bag, the product is loaded into the packaging bag, and the open end of the packaging bag is placed between the chain plate conveyors. The motor is started to drive the chain plate conveyors to rotate by the rotating roller, and the heating machine is started to heat the heating plate, thereby heating the chain plate conveyors, melting the opening of the plastic packaging bag, and then sealing the opening of the packaging bag, thus achieving the sealing function.
[0007] Preferably, a first spring is sleeved on the surface of the sliding rod, and both ends of the first spring are fixedly connected to the surface of the rotating roller and the side surface of the arc-shaped plate respectively.
[0008] The effects achieved by the above components are as follows: Under the action of the first spring, when the conical block and the trapezoidal block are separated, the arc-shaped plate can be contracted and attached to the surface of the rotating roller, thereby achieving the adjustment function.
[0009] Preferably, a round bar is fixedly connected to the side surface of the trapezoidal block, and the round bar is a rubber bar.
[0010] The effects achieved by the above components are as follows: Under the action of the round bar, the conical block will not directly contact the trapezoidal block, thereby avoiding the problem of rigid contact.
[0011] Preferably, anti-slip strips are fixedly connected to the surface of the arc-shaped plate, and the anti-slip strips are made of high-temperature resistant materials.
[0012] The effects achieved by the above components are as follows: Under the action of the anti-slip strips, the chain plate conveyors will not slip on the surface of the rotating roller, thereby achieving the anti-slip function. When it is necessary to increase the diameter of the rotating roller, the screw is rotated inside the circular groove, so that the conical block moves towards the inside of the circular groove and fits with the trapezoidal block. Under the action of the round bar, the conical block will not directly contact the trapezoidal block, thereby avoiding the problem of rigid contact. Then the sliding rod moves outwards, driving the arc-shaped plate to expand outwards. Under the action of the anti-slip strips, the chain plate conveyors will not slip on the surface of the rotating roller, thereby achieving the anti-slip function. When it is necessary to decrease the distance between the rotating rollers, the screw is rotated to make the conical block move away from the trapezoidal block. Then, under the action of the first spring, the arc-shaped plate contracts towards the surface of the rotating roller, thereby achieving the function of reducing the diameter of the rotating roller and thus achieving the adjustment function.
[0013] Preferably, the cleaning device includes a scraper fixedly connected to the side surface of the rectangular plate, and the scraper is made of high-temperature resistant materials.
[0014] The effects achieved by the above components are as follows: Under the action of the scraper, the plastic adhered to the surface of the chain plate conveyor belt can be cleaned, thereby avoiding the phenomenon that too much plastic adhered to the surface of the chain plate conveyor belt affects sealing.
[0015] Preferably, a driving machine is fixedly connected to the side surface of the rectangular plate, the output end of the driving machine is fixedly connected with a brush, and the bristles of the brush are steel bristles.
[0016] The effects achieved by the above components are as follows: Under the action of the brush, the plastic on the surface of the chain plate conveyor belt can be cleaned up.
[0017] Preferably, a collection box is arranged at the bottom of the brush, a clamping rod is inserted into the inner wall of the collection box, and the clamping rod is inserted into the interior of the rectangular plate.
[0018] The effects achieved by the above components are as follows: Under the action of the collection box, the plastic cleaned down can be collected, and under the action of the clamping rod, the collection box can be fixed at the bottom of the brush to collect plastic debris.
[0019] Preferably, a second spring is sleeved on the surface of the clamping rod, and both ends of the second spring are fixedly connected to the inner wall of the collection box and the end of the clamping rod away from the collection box respectively.
[0020] The effects achieved by the above components are as follows: Under the action of the second spring, the clamping rod is inserted into the interior of the rectangular plate in a self-locking manner for fixation. When it is necessary to clean the surface of the chain plate conveyor belt, start the driving machine to make the brush rotate, thereby cleaning the plastic on the surface of the chain plate conveyor belt. Under the action of the scraper, the firmly adhered plastic is cleaned down. Under the action of the collection box, the plastic cleaned down can be collected. Under the action of the second spring, the clamping rod is inserted into the interior of the rectangular plate in a self-locking manner for fixation, thereby achieving the cleaning effect.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.
[0022] In the present utility model, by providing an adjusting device, when it is necessary to increase the diameter of the roller, the screw rod is rotated inside the circular groove, so that the conical block moves towards the inside of the circular groove, and thus fits with the trapezoidal block. Under the action of the circular bar, the conical block does not directly contact the trapezoidal block, thereby avoiding the problem of rigid contact. Furthermore, the slide rod moves outwards, driving the arc-shaped plate to expand outwards. Under the action of the anti-slip strip, the chain plate conveyor belt does not slip on the surface of the roller, thus achieving the anti-slip effect. When it is necessary to decrease the distance between the rollers, the screw rod is rotated to make the conical block move away from the trapezoidal block. Then, under the action of the first spring, the arc-shaped plate contracts towards the surface of the roller, thus achieving the effect of reducing the diameter of the roller, and thus achieving the adjustment effect, thereby solving the problem that the distance between the chain plates of the chain plate sealing machine cannot be adjusted.

A heating plate 4 is fixedly connected to the side of the rectangular plate 1. A heating machine 8 is fixedly connected to the side of the rectangular plate 1. One side of the heating plate 4 is in contact with one side of the chain plate conveyor belt 5. An adjusting device 2 is arranged on the surface of the roller 6. A cleaning device 3 is arranged on the side of the rectangular plate 1. When it is necessary to seal the packaging bag, the product is loaded into the packaging bag, and the open end of the packaging bag is placed between the chain plate conveyor belts 5. The motor 7 is started to drive the roller 6 to drive the chain plate conveyor belt 5 to rotate. The heating machine 8 is started to heat the heating plate 4, and then the chain plate conveyor belt 5 is heated, so that the opening of the plastic packaging bag is melted by heating, and then the opening of the packaging bag is sealed, thus achieving the function of sealing.
[0029] Refer to Figure 3, the adjusting device 2 includes a circular groove 21 formed inside the rotating roller 6. A sliding rod is slidably connected inside the circular groove 21. One end of the sliding rod is fixedly connected to an arc-shaped plate 24, and the other end of the sliding rod is fixedly connected to a trapezoidal block 26. A screw rod 22 is rotatably connected inside the circular groove 21. One end of the screw rod 22 is rotatably connected to a conical block 23. Under the action of the conical block 23 and the trapezoidal block 26, the arc-shaped plate 24 can be expanded or contracted on the surface of the rotating roller 6, thereby achieving the function of adjusting the diameter of the rotating roller 6. When it is necessary to seal the packaging bag, the product is loaded into the packaging bag, and the open end of the packaging bag is placed between the chain plate conveyors 5. The motor 7 is started, so that the rotating roller 6 drives the chain plate conveyors 5 to rotate. The heating machine 8 is started to heat the heating plate 4, thereby heating the chain plate conveyors 5, melting the opening of the plastic packaging bag, and sealing the opening of the packaging bag, thus achieving the sealing function. A first spring 25 is sleeved on the surface of the sliding rod. The two ends of the first spring 25 are respectively fixedly connected to the surface of the rotating roller 6 and the side surface of the arc-shaped plate 24. Under the action of the first spring 25, when the conical block 23 is separated from the trapezoidal block 26, the arc-shaped plate 24 can be contracted and attached to the surface of the rotating roller 6, thereby achieving the adjustment function. A circular strip 27 is fixedly connected to the side surface of the trapezoidal block 26. The circular strip 27 is a rubber strip.

Under the action of the anti-slip strips 28, the chain plate conveyors 5 do not slip on the surface of the rotating roller 6, thereby achieving the anti-slip function. When it is necessary to increase the diameter of the rotating roller 6, the screw rod 22 is rotated inside the circular groove 21, so that the conical block 23 moves towards the inside of the circular groove 21 and fits with the trapezoidal block 26. Under the action of the circular strip 27, the conical block 23 does not directly contact the trapezoidal block 26, thereby avoiding the problem of rigid contact. Then the sliding rod moves outwards, driving the arc-shaped plate 24 to expand outwards. Under the action of the anti-slip strips 28, the chain plate conveyors 5 do not slip on the surface of the rotating roller 6, thereby achieving the anti-slip function. When it is necessary to decrease the distance between the rotating rollers 6, the screw rod 22 is rotated to make the conical block 23 away from the trapezoidal block 26. Then, under the action of the first spring 25, the arc-shaped plate 24 contracts towards the surface of the rotating roller 6, thereby achieving the function of reducing the diameter of the rotating roller 6 and thus achieving the adjustment function.
[0030] Refer to Figure 4, the cleaning device 3 includes a scraper 32 fixedly connected to the side surface of the rectangular plate 1. The scraper 32 is made of high-temperature resistant material. Under the action of the scraper 32, the plastic adhered to the surface of the chain plate conveyor belt 5 can be cleaned, thereby avoiding the phenomenon that too much plastic adhered to the surface of the chain plate conveyor belt 5 affects the sealing. A driving machine 31 is fixedly connected to the side surface of the rectangular plate 1. The output end of the driving machine 31 is fixedly connected with a brush 33.

Under the action of the clamping rod 35, the collection box 34 can be fixed at the bottom of the brush 33 to collect plastic debris. A second spring 36 is sleeved on the surface of the clamping rod 35. The two ends of the second spring 36 are respectively fixedly connected to the inner wall of the collection box 34 and the end of the clamping rod 35 far away from the collection box 34. Under the action of the second spring 36, the clamping rod 35 is inserted into the interior of the rectangular plate 1 in a self-locking state for fixation. When it is necessary to clean the surface of the chain plate conveyor belt 5, start the driving machine 31 to make the brush 33 rotate, thereby cleaning the plastic on the surface of the chain plate conveyor belt 5. Under the action of the scraper 32, the firmly adhered plastic is cleaned off. Under the action of the collection box 34, the plastic cleaned off can be collected. Under the action of the second spring 36, the clamping rod 35 is inserted into the interior of the rectangular plate 1 in a self-locking state for fixation, thereby achieving the cleaning effect.
[0031] Working principle: When the packaging bag sealer is needed and the packaging bag needs to be sealed, load the product inside the packaging bag, place the open end of the packaging bag between the chain plate conveyors 5, start the motor 7, so that the rotating roller 6 drives the chain plate conveyors 5 to rotate, start the heating machine 8, so that the heating plate 4 heats up, and then heats the chain plate conveyors 5, and then melts the opening of the plastic packaging bag, and then seals the opening of the packaging bag, thus achieving the sealing effect. When the diameter of the rotating roller 6 needs to be increased, rotate the screw rod 22 inside the circular groove 21, so that the tapered block 23 moves into the circular groove 21, and thus fits with the trapezoidal block 26. Under the action of the round bar 27, the tapered block 23 will not directly contact the trapezoidal block 26, thus avoiding the problem of rigid contact, and then making the sliding rod move outwards, thus driving the arc-shaped plate 24 to expand outwards. Under the action of the anti-slip strip 28, the chain plate conveyors 5 will not slip on the surface of the rotating roller 6, thus achieving the anti-slip effect. When the distance between the rotating rollers 6 needs to be reduced, rotate the screw rod 22, so that the tapered block 23 moves away from the trapezoidal block 26, and then under the action of the first spring 25, the arc-shaped plate 24 contracts towards the surface of the rotating roller 6, thus achieving the effect of reducing the diameter of the rotating roller 6, and thus achieving the adjustment effect. When the surface of the chain plate conveyors 5 needs to be cleaned, start the drive machine 31, so that the brush 33 rotates, and then clean the plastic on the surface of the chain plate conveyors 5. Under the action of the scraping plate 32, the firmly adhered plastic is cleaned off. Under the action of the collection box 34, the cleaned plastic can be collected. Under the action of the second spring 36, the clamping rod 35 is inserted into the rectangular plate 1 in a self-locking state for fixation, thus achieving the cleaning effect.
