Description

Technical Field

[0001] This application relates to the field of industrial paper tube packaging, and more particularly to a plastic heat-sealing device. Background Technology

[0002] Industrial paper tubes are tubular paper materials used in industrial applications. They are made by bonding and winding multiple layers of paper with adhesive. They are widely used in industries such as textiles, printing, packaging, and plastic films, serving as winding mandrels or support materials. Industrial paper tubes typically require packaging with plastic film.

[0003] In the relevant technology, the industrial paper tube is first placed in a plastic packaging film, then the plastic packaging film is cut with a blade, and then the edges of the plastic packaging film are sealed with a hot press. This operation is relatively troublesome, resulting in low packaging efficiency of the industrial paper tube, so it needs to be improved. Utility Model Content

[0004] To improve the packaging efficiency of industrial paper tubes, this application provides a plastic heat-sealing device.

[0005] The plastic heat-sealing edge-sealing device provided in this application adopts the following technical solution:

[0006] A plastic hot-cutting and sealing device includes a frame, two conveyor belts, a feeding assembly, and a hot-cutting assembly. The frame includes a frame body. The two conveyor belts are spaced apart along the length of the frame body. The feeding assembly includes a feeding rack and two feeding plates. The feeding rack is located on one side of one of the conveyor belts, and the two feeding plates are located on the frame body and on the upper and lower sides of the conveyor belt. The hot-cutting assembly is located between the two conveyor belts. The hot-cutting assembly includes a hot-cutting seat, an abutment seat, a driving member, and two hot-pressing seats. The hot-cutting seat and the abutment seat are slidably connected to the frame body in a vertical direction. The driving member is located on the frame body and is used to drive the hot-cutting seat and the abutment seat to slide in opposite directions. The two hot-pressing seats are spaced apart along the width of the frame body and located above the other conveyor belt.

[0007] By adopting the above technical solution, in practical applications, one layer of plastic packaging film is fed onto one feeding plate via a feeding rack, and the other layer of plastic packaging film is fed onto another feeding plate via a feeding rack, thereby achieving the guiding feeding of the plastic packaging film. The industrial paper tube is placed on one conveyor belt and transported to the other conveyor belt. During this process, the industrial paper tube passes between the two layers of plastic packaging film, thereby driving the plastic packaging film to move. The driving component drives the heat cutting seat and the abutment seat to move closer to each other, so as to cut and press and fix one end of the two layers of plastic packaging film. The two heat pressing seats heat-press and fix the two sides of the two layers of plastic packaging film, thereby realizing the automatic packaging of industrial paper tubes and improving the packaging efficiency of industrial paper tubes.

[0008] Preferably, the frame further includes a transfer roller, which is rotatably connected to the frame and located between the two conveyor belts.

[0009] By adopting the above technical solution and setting up a transfer roller, the transfer roller supports the industrial paper tube when it is transported from one conveyor belt to another, thereby improving the stability of the industrial paper tube transport.

[0010] Preferably, the frame further includes two guide columns, which are disposed on the frame and are both arranged in a vertical direction. The two ends of the hot cutting seat and the two ends of the abutment seat are respectively slidably connected to the two guide columns.

[0011] By adopting the above technical solution and setting two guide columns, the sliding of the heat-cutting seat and the abutment seat with the frame can be realized. The structure is simple and the sliding stability is high.

[0012] Preferably, the driving component includes two telescopic cylinders, a first connecting rod, and a second connecting rod. The two telescopic cylinders are spaced apart along the length of the frame. The two ends of the first connecting rod are rotatably connected to one end of one of the telescopic cylinders and one end of the heat-cutting seat, and the two ends of the second connecting rod are rotatably connected to the other telescopic cylinder and one end of the abutment seat.

[0013] By adopting the above technical solution, and by setting two telescopic cylinders, a first connecting rod, and a second connecting rod, the overall structure of the driving component is compact, and the stability of driving the hot cutting seat and the abutment seat to slide is guaranteed.

[0014] Preferably, the hot cutting assembly further includes two stroke sensors and a controller. The two stroke sensors are respectively disposed on the two feeding plates, and the controller is electrically connected to the two telescopic cylinders and the two stroke sensors.

[0015] By adopting the above technical solution, and by setting two stroke sensors and a controller to control the sliding position of the heat-cutting seat and the abutment seat, the heat-cutting effect on the plastic packaging film is guaranteed.

[0016] Preferably, the plastic hot-cutting and sealing device further includes two limiting components, which are respectively located above the two conveyor belts. The limiting components include a first limiting tube and a second limiting tube, which are spaced apart from each other on the frame along the width direction of the frame.

[0017] By adopting the above technical solution, and by setting a first limiting tube and a second limiting tube, when the industrial paper tube is placed on the conveyor belt, the industrial paper tube is limited between the first limiting tube and the second limiting tube, thereby improving the stability of the industrial paper tube conveying.

[0018] Preferably, the limiting component further includes a plurality of sliding rods, which are spaced apart along the length of the frame and are located on the side of the first limiting tube away from the second limiting tube and are slidably connected to the frame.

[0019] By adopting the above technical solution and setting multiple sliding rods, the sliding of the first limiting tube is realized, thereby adjusting the distance between the first limiting tube and the second limiting tube, so as to be suitable for industrial paper tubes of different sizes.

[0020] Preferably, the limiting component further includes a plurality of pulleys, which are spaced apart along the length of the frame and rotatably connected to the side of the second limiting tube near the first limiting tube.

[0021] By adopting the above technical solution and setting multiple pulleys, the efficiency of industrial paper tube conveying can be improved.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. One layer of plastic packaging film is fed onto one feeding plate via a feeding rack, and the other layer of plastic packaging film is fed onto another feeding plate via a feeding rack, thus guiding the feeding of the plastic packaging film. The industrial paper tube is placed on one conveyor belt and transported to the other conveyor belt. During this process, the industrial paper tube passes between the two layers of plastic packaging film, thereby moving the plastic packaging film. The driving component drives the heat cutting seat and the abutment seat to move closer to each other, so as to cut and press one end of the two layers of plastic packaging film. The two heat pressing seats heat press and fix the two sides of the two layers of plastic packaging film, thus realizing the automatic packaging of industrial paper tubes and improving the packaging efficiency of industrial paper tubes.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a plastic heat-sealing device.

[0032] Reference Figure 1 The plastic hot-cutting and sealing device includes a frame 1, two conveyor belts 2, a feeding assembly 3 and a hot-cutting assembly 4. The frame 1 includes a frame 11 placed on the ground. The two conveyor belts 2 are spaced apart along the length of the frame 11 and are installed in the frame 11.

[0033] The feeding assembly 3 includes a feeding rack 31 and two feeding plates 32. The feeding rack 31 is placed on the ground and located on one side of one of the conveyor belts 2. The feeding rack 31 uses multiple rotating feeding rollers to allow plastic packaging film to be wound and installed. Both feeding plates 32 are arranged in a right-angled triangular shape and are fixedly connected to the frame 11 and located on the upper and lower sides of the corresponding feeding rack 31 of the conveyor belt 2.

[0034] Reference Figure 1 and Figure 2The hot-cutting assembly 4 is located between the two conveyor belts 2. Specifically, the hot-cutting assembly 4 includes a hot-cutting seat 41, an abutment seat 42, a driving member 43, and two hot-pressing seats 44. The hot-cutting seat 41 and the abutment seat 42 are arranged opposite to each other and are both slidably connected to the frame 11 in the vertical direction. The driving member 43 is fixedly connected to the frame 11 and is used to drive the hot-cutting seat 41 and the abutment seat 42 to slide in opposite directions. The two hot-pressing seats 44 are fixedly connected to the frame 11 and are spaced apart along the width direction of the frame 11. The two hot-pressing seats 44 are located above the conveyor belt 2 away from the loading rack 31.

[0035] In practical applications, one layer of plastic packaging film is fed through the feeding rack 31 and one of the feeding plates 32, and the other layer of plastic packaging film is fed through the feeding rack 31 and another feeding plate 32 to achieve the guiding feeding of plastic packaging film, and one end of each side of the plastic packaging film is fixed together.

[0036] During operation, the industrial paper tube is first placed on one of the conveyor belts 2, and then transported to another conveyor belt 2 under the action of the conveyor belt 2. During this process, the industrial paper tube passes between the two layers of plastic packaging film, thereby moving the plastic packaging film. The driving component 43 drives the heat cutting seat 41 and the abutment seat 42 to approach each other, so that the heat cutting seat 41 abuts against the abutment seat 42, thereby cutting and pressing the other end of the two layers of plastic packaging film. The two hot pressing seats 44 heat-press and fix the two sides of the two layers of plastic packaging film, thus realizing the automatic packaging of industrial paper tubes and improving the packaging efficiency of industrial paper tubes.

[0037] Reference Figure 1 and Figure 2 In some embodiments, the frame 1 further includes a transfer roller 12, which is arranged along the width direction of the frame 11 and rotatably connected to the frame 11. The transfer roller 12 is located between two conveyor belts 2. When the industrial paper tube is transported from one of the conveyor belts 2 to the other conveyor belt 2, the transfer roller 12 supports the industrial paper tube to improve the stability of the industrial paper tube transport.

[0038] Reference Figure 2 In some embodiments, the frame 1 further includes two guide columns 13, which are vertically fixed to the frame 11 and spaced apart along the width of the frame 11. The two ends of the hot cutting seat 41 are slidably connected to the two guide columns 13, and the two ends of the abutment seat 42 are slidably connected to the two guide columns 13, so as to realize the sliding of the hot cutting seat 41 and the abutment seat 42 with the frame 11. The structure is simple and the sliding stability is high.

[0039] In some embodiments, the drive component 43 includes two telescopic cylinders 431, a first connecting rod 432, and a second connecting rod 433. The telescopic cylinders 431 can be, but are not limited to, pneumatic cylinders, hydraulic cylinders, electric push cylinders, etc., and this application does not impose any restrictions. The two telescopic cylinders 431 are spaced apart along the length direction of the frame 11. One end of the first connecting rod 432 is rotatably connected to the power output shaft of one of the telescopic cylinders 431, and the other end is rotatably connected to one end of the hot-cutting seat 41. One end of the second connecting rod 433 is rotatably connected to the power output shaft of the other telescopic cylinder 431, and the other end is rotatably connected to one end of the abutment seat 42. This makes the overall structure of the drive component 43 compact and ensures the stability of driving the hot-cutting seat 41 and the abutment seat 42 to slide. It should be noted that there can be two drive components 43, which are spaced apart along the width direction of the frame 11, and synchronously drive the hot-cutting seat 41 and the abutment seat 42 to slide, thereby improving the stability of the sliding of the hot-cutting seat 41 and the abutment seat 42.

[0040] Reference Figure 1 In some embodiments, the heat-cutting assembly 4 further includes two stroke sensors 45 and a controller (not shown in the figure). The two stroke sensors 45 are fixedly connected to the two feeding plates 32, and the two stroke sensors 45 are respectively matched with the heat-cutting seat 41 and the abutment seat 42. The controller is electrically connected to the two telescopic cylinders 431 and the two stroke sensors 45. When the heat-cutting seat 41 or the abutment seat 42 slides, the stroke sensors 45 match the corresponding positions of the heat-cutting seat 41 or the abutment seat 42. At this time, the stroke sensors 45 transmit the signal to the controller, so that the controller controls the telescopic cylinders 431 to stop working, thereby limiting the heat-cutting seat 41 or the abutment seat 42 from continuing to slide, so as to control the sliding position of the heat-cutting seat 41 and the abutment seat 42, thereby ensuring the heat-cutting effect on the plastic packaging film.

[0041] Reference Figure 1 and Figure 3 In some embodiments, the plastic heat-sealing device further includes two limiting components 5, which are respectively located above the two conveyor belts 2. Specifically, the limiting components 5 include a first limiting tube 51 and a second limiting tube 52, which are installed at intervals along the width direction of the frame 11. When the industrial paper tube is placed on the conveyor belt 2, the industrial paper tube is limited between the first limiting tube 51 and the second limiting tube 52 to improve the stability of the industrial paper tube conveying.

[0042] Reference Figure 3In some embodiments, the limiting component 5 further includes multiple sliding rods 53, which are spaced apart along the length of the frame 11. The multiple sliding rods 53 are fixedly connected to the side of the first limiting tube 51 away from the second limiting tube 52 and slidably connected to the frame 11. By sliding the multiple sliding rods 53, the first limiting tube 51 can be slidably moved, thereby adjusting the distance between the first limiting tube 51 and the second limiting tube 52 to accommodate industrial paper tubes of different sizes, thus improving the applicability of the plastic heat-sealing device. The sliding rods 53 are abutted by abutting members 54 threaded to the frame 11 to limit the sliding of the sliding rods 53, ensuring the stability of the first limiting tube 51 after its position is adjusted.

[0043] In some embodiments, the limiting component 5 further includes a plurality of pulleys 55, which are spaced apart along the length of the frame 11 and rotatably connected to the side of the second limiting tube 52 near the first limiting tube 51. When the industrial paper tube is conveyed by the conveyor belt 2, the industrial paper tube abuts against the pulleys 55 to improve the conveying effect of the industrial paper tube.

[0044] The implementation principle of this embodiment is as follows: In practical applications, one layer of plastic packaging film is fed through the feeding rack 31 and one of the feeding plates 32, and the other layer of plastic packaging film is fed through the feeding rack 31 and another feeding plate 32 to achieve the guiding feeding of plastic packaging film, and one end of each side of the plastic packaging film is fixed together.

[0045] During operation, the industrial paper tube is first placed on one of the conveyor belts 2, and then transported to another conveyor belt 2 under the action of the conveyor belt 2. During this process, the industrial paper tube passes between the two layers of plastic packaging film, thereby moving the plastic packaging film. The driving component 43 drives the heat cutting seat 41 and the abutment seat 42 to approach each other, so that the heat cutting seat 41 abuts against the abutment seat 42, thereby cutting and pressing the other end of the two layers of plastic packaging film. The two hot pressing seats 44 heat-press and fix the two sides of the two layers of plastic packaging film, thus realizing the automatic packaging of industrial paper tubes and improving the packaging efficiency of industrial paper tubes.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
