Description

Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, specifically a rapid heat sealing device for tea packaging bags. Background Technology

[0002] As a major global tea producer and consumer, China's large-scale production demands highly efficient packaging processes. Traditional manual methods or inefficient equipment can no longer meet production capacity requirements. Tea is susceptible to moisture and oxidation, leading to a decline in quality. Rapid heat sealing devices effectively extend the shelf life of tea and preserve its aroma and taste by shortening the sealing time and reducing residual air inside the packaging bag.

[0003] In order to improve sealing efficiency, existing devices usually use a conveyor belt to seal tea packaging bags. When the tea is transported by the conveyor belt to the area directly below the heat sealing head, the cylinder is activated to drive the heat sealing head to descend quickly, thereby sealing the tea packaging bag quickly.

[0004] However, when sealing tea packaging bags, tea fragments and melted residue from the packaging bag may adhere to the surface of the heat sealer, preventing the heat from being transferred to the packaging bag in a timely manner. This affects the heat sealing quality of the packaging bag and may also contaminate subsequent packaging bags. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rapid heat sealing device for tea packaging bags, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A rapid heat-sealing device for tea packaging bags includes: a conveyor belt with an mounting plate on it, a support frame on the mounting plate, a support plate on the support frame, a heat-sealing head on the support plate, and a metal plate on the mounting plate; it also includes: a cleaning component mounted on the support plate, comprising an inclined plate and a spring, the inclined plate on the support frame, the spring on the support plate, a connecting rod on the spring, a placement block on the connecting rod, and a cleaning component on the placement block; and a collection component mounted on the placement block, comprising a collection box on the placement block, a positioning block on the collection box, and a threaded post on the positioning block.

[0008] Furthermore, the cleaning component also includes a groove on one side of the support plate, a slide rod fixedly installed inside the groove, and a slider slidably installed outside the slide rod.

[0009] Furthermore, a spring is positioned between the slider and the groove, and the spring is located on the outside of the slide rod.

[0010] Furthermore, the connecting rod is installed on the side of the slider away from the slide groove, and the placement block is set on the side of the connecting rod away from the support frame, with the connecting rod in contact with the inclined plate.

[0011] Furthermore, the cleaning component is installed on one side of the placement block, and the heat-sealed head is in contact with the cleaning component.

[0012] Furthermore, the collection component also includes two sets of positioning blocks evenly installed on one end of the upper surface of the collection box, with positioning slots provided on the placement blocks corresponding to the positioning blocks, and the positioning blocks and positioning slots matching each other.

[0013] Furthermore, a handle is provided at the other end of the collection box, and a sloping groove is provided on the placement block, with the sloping groove located between the collection box and the cleaning component.

[0014] Furthermore, a threaded hole is provided on one side of the placement block, and the threaded hole penetrates the positioning groove and the positioning block, with the threaded post matching the threaded hole.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. When sealing tea packaging bags, the packaging bags are transported between the heat sealing head and the metal plate via a conveyor belt. By controlling the downward pressure of the heat sealing head, the packaging bags can be quickly sealed. After sealing the tea packaging bags, the support plate is moved in the opposite direction to the metal plate, so that the inclined side of the inclined plate squeezes the connecting rod, which drives the slider to slide in the groove. This allows the cleaning component to clean the surface of the heat sealing head, thus preventing tea fragments and melted packaging bag residue from remaining on the surface of the heat sealing head. This ensures that the heat sealing head can stably and quickly heat seal the packaging bags.

[0017] 2. Impurities cleaned off the heat sealing head by the cleaning parts can quickly slide into the collection box through the inclined groove, thus preventing lighter impurities from drifting to other places. When the collection box is full, the locking of the collection box can be released by turning the threaded column, making it easy for the staff to remove the collection box from the placement block and transfer the impurities inside the collection box to other places for centralized treatment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 - Figure 5 As shown, this utility model provides a rapid heat sealing device for tea packaging bags, including: a conveyor belt 1, an mounting plate 2 on the conveyor belt 1, a support frame 3 on the mounting plate 2, a support plate 6 on the support frame 3, a heat sealing head 21 on the support plate 6, and a metal plate 4 on the mounting plate 2. It also includes: a cleaning assembly on the support plate 6, the cleaning assembly including an inclined plate 5 and a spring 14, the inclined plate 5 being mounted on the support frame 3, the spring 14 being mounted on the support plate 6, a connecting rod 9 on the spring 14, a placement block 11 on the connecting rod 9, and a cleaning component 10 on the placement block 11; a collection assembly on the placement block 11, the collection assembly including a collection box 16 on the placement block 11, a positioning block 18 on the collection box 16, and a threaded post 19 on the positioning block 18.

[0027] In the above scheme:

[0028] 1. The transmission of the conveyor belt 1 can improve the conveying efficiency of tea packaging bags, which greatly improves the heat sealing efficiency of tea packaging bags and facilitates the heat sealing of large batches of tea packaging bags.

[0029] 2. After heat sealing the packaging bag, the heat sealing head 21 needs to be driven back to its original position so that subsequent packaging bags can be heat sealed. During this process, as the heat sealing head 21 rises, the inclined plate 5 with the inclined side can squeeze the connecting rod 9, thereby driving the cleaning component 10 to clean the surface of the heat sealing head 21.

[0030] 3. After cleaning, the impurities fall into the collection box 16. When there are a lot of impurities collected in the collection box 16, the restriction on the collection box 16 can be released by turning the threaded column 19. Then, the staff can pull the handle 17 to disassemble the collection box 16, so that the staff can transfer the collection box 16 to other places for centralized processing.

[0031] In this embodiment, the cleaning component also includes a groove 7 provided on one side of the support plate 6, a slide rod 12 fixedly provided inside the groove 7, and a slider 13 slidably provided outside the slide rod 12.

[0032] In the above scheme, the movement position of the cleaning component 10 is easily limited by the cooperation between the slider 13 and the groove 7.

[0033] In this embodiment, the spring 14 is disposed between the slider 13 and the groove 7, and the spring 14 is disposed on the outside of the slide rod 12.

[0034] In the above scheme, the spring 14 is located on the outside of the slide bar 12, which can be stretched or compressed to prevent the spring 14 from bending and to ensure that the spring 14 can work normally and stably.

[0035] In this embodiment, the connecting rod 9 is installed on the side of the slider 13 away from the slide groove 7, and the placement block 11 is disposed on the side of the connecting rod 9 away from the support frame 3. The connecting rod 9 is in contact with the inclined plate 5.

[0036] In the above scheme: during the rising process of the heat sealing head 21, the connecting rod 9 comes into contact with the inclined plate 5, and then the inclined plate 5 will squeeze the connecting rod 9, which will drive the cleaning part 10 to move and clean the heat sealing head 21.

[0037] In this embodiment, the cleaning component 10 is installed on one side of the placement block 11, and the heat sealing head 21 is in contact with the cleaning component 10.

[0038] In the above scheme, the cleaning component 10 can thoroughly clean the impurities on the surface of the heat seal head 21 during the movement process.

[0039] In this embodiment, the collection component also includes two sets of positioning blocks 18 evenly installed on one end of the upper surface of the collection box 16, and a positioning groove 20 is provided on the placement block 11 corresponding to the positioning block 18, and the positioning block 18 matches the positioning groove 20.

[0040] In the above scheme, the cooperation between the positioning block 18 and the positioning groove 20 can facilitate the quick pre-positioning effect when installing the collection box 16.

[0041] In this embodiment, a handle 17 is provided at the other end of the collection box 16, and a sloping groove 15 is provided on the placement block 11, with the sloping groove 15 located between the collection box 16 and the cleaning component 10.

[0042] In the above scheme, by pulling the handle 17, it is easy for staff to remove the collection box 16 from the placement block 11.

[0043] In this embodiment, a threaded hole 8 is provided on one side of the placement block 11, and the threaded hole 8 passes through the positioning groove 20 and the positioning block 18, and the threaded post 19 matches the threaded hole 8.

[0044] In the above scheme, the collection box 16 can be quickly locked onto the placement block 11 by the cooperation of the threaded post 19 and the threaded hole 8.

[0045] In this embodiment, during the sealing of tea packaging bags, the worker places the tea packaging bags diagonally on the conveyor belt 1, so that the end of the tea packaging bag to be sealed is between the metal plate 4 and the heat sealing head 21. When the tea packaging bag is transported by the conveyor belt 1 and moves directly under the heat sealing head 21, the heat sealing head 21 is controlled to move towards the metal plate 4, so that the heat sealing head 21 and the metal plate 4 cooperate to squeeze the packaging bag. The heat generated by the heat sealing head 21 can heat seal the packaging bag. In order to avoid tea fragments and molten residue from the packaging bag remaining on the heat seal and affecting subsequent packaging sealing, the heat sealing head returns to its original position after sealing the packaging bag. At this time, the inclined plate 5 will squeeze the connecting rod 9, causing the slider 13 to slide in the slide groove 7, thereby driving the cleaning component 10 to clean the surface of the heat sealing head 21, so that the surface of the heat sealing head 21 can be kept clean. When the heat sealing head 21 moves towards the metal plate 4, the elastic force of the spring 14 can drive the cleaning part 10 back to its original position, preventing the cleaning part 10 from affecting the normal operation of the heat sealing head 21. The impurities cleaned by the cleaning part 10 can quickly slide into the collection box 16 through the inclined groove 15, thus preventing lighter impurities from scattering everywhere. When a large amount of impurities are collected in the collection box 16, the operator can quickly release the restriction on the collection box 16 by turning the threaded post 19. Then, the operator can pull the handle 17 to make the positioning block 18 disengage from the positioning groove 20, so that the operator can transfer the impurities in the collection box 16 to other places for processing. After the impurities are processed, the positioning block 18 is controlled to snap into the corresponding positioning groove 20. At this time, the threaded post 19 and the threaded hole 8 are aligned. By turning the threaded post 19 in the opposite direction, the collection box 16 can be fixed.
