Description

Technical Field

[0001] This utility model relates to the field of packaging processing technology, specifically to a plastic sealing device for packaging processing. Background Technology

[0002] In daily life, most products we use or consume require packaging. Packaging can enhance the product's perceived quality, provide appropriate protection, extend shelf life, and maintain cleanliness. Among these, CN 221606260 U discloses a plastic sealing device for packaging processing, comprising: a mounting frame; a fixed pressing platform located at one end of the mounting frame; and an ultrasonic pressing unit located at the end of the mounting frame away from the fixed pressing platform. The fixed pressing platform has protruding posts, and the ultrasonic pressing unit has limiting grooves. When the ultrasonic pressing unit and the fixed pressing platform abut against both sides of the packaging bag, the limiting grooves contact and connect with the protruding posts. This invention, by having the ultrasonic pressing unit and the fixed pressing platform approach and abut against the outside of the packaging bag, uses the limiting grooves and protruding posts to replace the plastic cover and pressing surface in violent collision contact, reducing the rigid contact between the ultrasonic pressing unit and the fixed pressing platform during extrusion and preventing damage to the ultrasonic transducer, thus extending the service life of the ultrasonic transducer.

[0003] The above solution has the following problems: the sealing position is fixed and cannot be adjusted according to the amount of material in the plastic bag. This can easily result in a large amount of empty space inside the plastic bag after sealing, causing the material inside the plastic bag to move around during transportation and making the plastic bag prone to breakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a plastic sealing device for packaging processing, which has the advantage of adjusting the sealing position of plastic bags, thus avoiding the problem of large empty spaces inside the plastic bag and material shaking causing the plastic bag to break.

[0005] To achieve the purpose of adjusting the sealing position of plastic bags, this utility model provides the following technical solution:

[0006] A plastic sealing device for packaging processing includes a main frame, a fixing component slidably mounted on the side wall of the main frame for fixing the opening of a plastic bag, and a sealing component slidably mounted on the side wall of the main frame for sealing the edges of the plastic bag. The device also includes:

[0007] The fixing component includes a first bidirectional threaded rod, which is rotatably mounted on the inner wall of the main frame. The first bidirectional threaded rod has a first sliding block threadedly connected to both side walls of the first bidirectional threaded rod. A connecting plate is fixedly connected to the side wall of the first sliding block. Multiple sets of telescopic cylinders are fixedly connected to the bottom of the connecting plate. A fixing frame is fixedly connected to the top of the telescopic cylinder. A threaded bolt is threadedly connected to the top of the fixing frame. A fixing plate is rotatably connected to the bottom end of the threaded bolt located in the inner cavity of the fixing frame.

[0008] According to some embodiments, the edge sealing assembly includes a second bidirectional threaded rod, which is rotatably mounted on the inner wall of the main frame and located below the first bidirectional threaded rod. The two side walls of the second bidirectional threaded rod are threaded with second sliding blocks, and the side walls of the second sliding blocks are fixedly connected with sleeve plates. The inner wall of the sleeve plates is slidably connected with heating blocks, and a spring is fixedly connected between the heating blocks and the sleeve plates.

[0009] According to some embodiments, a first servo motor is fixedly connected to the side wall of the main frame, the output end of the first servo motor is fixedly connected to a first bidirectional threaded rod, a second servo motor is fixedly connected to the side wall of the main frame located below the first servo motor, and the second servo motor is fixedly connected to the second bidirectional threaded rod. Two connecting columns are fixedly connected to both sides of the inner wall of the main frame, and the connecting plate and the sleeve plate are slidably connected to the connecting columns. Beneficial effects

[0010] This utility model provides a plastic sealing device for packaging processing, which has the following beneficial effects:

[0011] This plastic sealing equipment for packaging processing places the opening of the plastic bag inside the fixed frame. By rotating the threaded bolt, the fixed plate moves down to fix and open the opening of the plastic bag, allowing materials to be added inside. During sealing, the height of the fixed frame can be adjusted by the telescopic cylinder to adjust the height of the plastic bag, making it easy to adjust the sealing position of the sealing components on the plastic bag. This allows the sealing height to be adjusted according to the amount of material contained, thereby ensuring that there is little empty space in the sealed plastic bag and that the material does not move around, thus protecting the plastic bag.

[0012] This plastic sealing equipment for packaging processing utilizes the threaded connection between the second bidirectional threaded rod and the second sliding block, allowing the second sliding block to drive the sleeve plate to slide towards the center. This, in turn, uses the heating block to clamp the plastic bag and seal the edge of the plastic bag. Furthermore, since there is a spring between the heating block and the sleeve plate, the spring can act as a buffer, preventing the heating blocks from colliding violently with each other and thus avoiding damage to the heating blocks.

[0018] 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.

[0019] Reference Figures 1-4 A plastic sealing device for packaging processing includes a main frame 1, a fixing component 2 slidably mounted on the side wall of the main frame 1 for fixing the opening of a plastic bag, and a sealing component 3 slidably mounted on the side wall of the main frame 1 for sealing the plastic bag. The device also includes:

[0020] The fixing component 2 includes a first bidirectional threaded rod 201, which is rotatably mounted on the inner wall of the main frame 1. Both sides of the first bidirectional threaded rod 201 are threadedly connected to a first sliding block 202. A connecting plate 203 is fixedly connected to the side wall of the first sliding block 202. Multiple sets of telescopic cylinders 204 are fixedly connected to the bottom of the connecting plate 203. A fixing frame 205 is fixedly connected to the top of the telescopic cylinder 204.

[0021] The top of the fixing frame 205 is threadedly connected to a threaded bolt 206, and the bottom of the threaded bolt 206 located in the inner cavity of the fixing frame 205 is rotatably connected to a fixing plate 207.

[0022] It should be noted that: driving the first bidirectional threaded rod 201 to rotate utilizes the threaded connection between the first bidirectional threaded rod 201 and the first sliding block 202, causing the first sliding block 202 to move the connecting plate 203 closer to or further away from the center of the main frame 1. This adjusts the spacing of the fixing frame 205, making it easier to fix the opening of the plastic bag. Specifically, the opening of the plastic bag is placed below the fixing plate 207 inside the fixing frame 205. Then, rotating the threaded bolt 206 causes the fixing plate 207 to move down, thereby fixing and opening the opening of the plastic bag, allowing materials to be added to the plastic bag. When sealing, the height of the fixing frame 205 can be adjusted by the telescopic cylinder 204 to adjust the height of the plastic bag, facilitating the adjustment of the sealing position of the sealing assembly 3 on the plastic bag. This allows the sealing height to be adjusted according to the amount of material contained, thereby ensuring that there is little empty space in the sealed plastic bag and that the material does not move around.

[0023] Reference Figures 1-4 The edge sealing assembly 3 includes a second bidirectional threaded rod 301, which is rotatably mounted on the inner wall of the main frame 1, and is located below the first bidirectional threaded rod 201.

[0024] The second bidirectional threaded rod 301 has a second sliding block 302 threadedly connected to both side walls, and a sleeve 303 is fixedly connected to the side wall of the second sliding block 302.

[0025] A heating block 304 is slidably connected to the inner wall of the sleeve 303, and a spring 305 is fixedly connected between the heating block 304 and the sleeve 303.

[0026] It should be noted that: the second bidirectional threaded rod 301 is driven to rotate, and the threaded connection between the second bidirectional threaded rod 301 and the second sliding block 302 allows the second sliding block 302 to drive the sleeve plate 303 to slide towards the center, thereby using the heating block 304 to clamp the plastic bag and seal the edge of the plastic bag. In addition, since there is a spring 305 between the heating block 304 and the sleeve plate 303, the spring 305 can play a buffering role to avoid the heating blocks 304 from violently colliding with each other, which would easily damage the heating blocks 304.

[0027] Reference Figures 1-4 The first servo motor 4 is fixedly connected to the side wall of the main frame 1, and the output end of the first servo motor 4 is fixedly connected to the first bidirectional threaded rod 201.

[0028] A second servo motor 401 is fixedly connected to the side wall of the main frame 1 below the first servo motor 4, and the second servo motor 401 is fixedly connected to the second bidirectional threaded rod 301.

[0029] Two connecting columns 402 are fixedly connected to both sides of the inner wall of the main frame 1, and the connecting plate 203 and the sleeve plate 303 are slidably connected to the connecting columns 402.

[0030] It should be noted that the first servo motor 4 drives the first bidirectional threaded rod 201 to rotate, and the second servo motor 401 drives the second bidirectional threaded rod 301 to rotate. The setting of the connecting column 402 facilitates the sliding of the connecting plate 203 and the sleeve plate 303 in the inner cavity of the main frame 1.

[0031] Operation method: Drive the first servo motor 4 to rotate the first bidirectional threaded rod 201. Utilize the threaded connection between the first bidirectional threaded rod 201 and the first sliding block 202 to cause the first sliding block 202 to move the connecting plate 203 closer to or further away from the center of the main frame 1. This adjusts the spacing of the fixing frame 205, making it easier to fix the opening of the plastic bag. That is, place the opening of the plastic bag below the fixing plate 207 in the inner cavity of the fixing frame 205, and then rotate the threaded bolt 206 to move the fixing plate 207 down, thereby fixing and opening the opening of the plastic bag. Materials can be added into the plastic bag. The height of the fixing frame 205 can be adjusted by the telescopic cylinder 204 to adjust the height of the plastic bag, making it easy to adjust the sealing position of the sealing assembly 3 on the plastic bag. This allows the sealing height to be adjusted according to the amount of material, thereby ensuring that there is little empty space in the closed plastic bag and that the material does not move around.

[0032] The second servo motor 401 drives the second bidirectional threaded rod 301 to rotate. The threaded connection between the second bidirectional threaded rod 301 and the second sliding block 302 allows the second sliding block 302 to drive the sleeve plate 303 to slide towards the center. The heating block 304 then clamps the plastic bag and seals the edge of the plastic bag. Since there is a spring 305 between the heating block 304 and the sleeve plate 303, the spring 305 can play a buffering role to prevent the heating blocks 304 from colliding violently with each other, which would easily damage the heating blocks 304.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
