Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically to a packaging bag sealing and cutting device for a disposable tableware packaging device. Background Technology

[0002] The packaging bags for disposable tableware packaging devices are film-type packaging materials specifically designed for the automated packaging of disposable tableware such as bowls, chopsticks, spoons, forks, etc., in combination or individually. They need to be adapted to the sealing, cutting, and forming processes of the packaging device to ultimately form independent, sealed tableware packaging products.

[0003] Traditional disposable tableware packaging methods mostly involve manual packaging. When using traditional hand-held sealing and cutting tools, such as simple heat sealers, the sealing and cutting position relies entirely on experience, which can easily lead to sealing and cutting deviations. This can result in tableware being exposed or packaging being wrinkled, which in turn leads to incomplete sealing after cutting, resulting in air leakage and water ingress. Especially when packaging multiple sets of tableware, side gaps can directly affect the hygiene of the tableware and increase the risk of contamination. At the same time, the efficiency of manual work gradually decreases after a long period of time, making it difficult to adapt to large-scale production, and thus has certain shortcomings.

[0014] 1. This utility model employs a continuous process from pre-compression to end sealing and cutting, then to side sealing and cutting, and finally to secondary end sealing and cutting. Each step is synchronized via a conveyor belt, significantly reducing manual operation. First, disposable tableware automatically enters the semi-tubular film via the conveyor belt. Second, the side pre-compression mechanism automatically aligns the sides, and the heating film cutter group and side sealing and cutting mechanism sequentially complete the end and side sealing and cutting according to the conveying rhythm, without requiring manual adjustment of the sealing and cutting sequence. Finally, as the unsealed end of the film is conveyed forward, it automatically undergoes secondary sealing and cutting to form a complete package. The entire process only requires initial adjustment of mechanism parameters via a handwheel; subsequent processing can then be automated and continuous.

[0015] 2. This utility model offers strong packaging adaptability and compatibility with various specifications of disposable tableware. Through its adjustable mechanism and semi-tubular forming design, the equipment can flexibly adapt to packaging needs for disposable tableware of different sizes and quantities. Firstly, the triangular plate can be adjusted in height via a height adjustment bracket, and in conjunction with the guide rollers to adjust the film tension, it can change the folding width of the semi-tubular film, adapting to packaging sizes ranging from single sets of spoons and forks to multi-set tableware. Secondly, the screw two of the side pre-pressing mechanism can adjust the pre-pressing height, and the screw one of the heating film cutter assembly can adjust the sealing and cutting height. Together, these two mechanisms can adapt to films of different thicknesses and can precisely control the sealing and cutting position according to the height of the tableware, avoiding problems such as packaging misalignment and incomplete sealing caused by changes in tableware specifications.

[0022] 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.

[0023] Example 1: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a packaging bag sealing and cutting device for disposable tableware packaging, including a processing machine tool 1, a side pre-compression mechanism 2 provided on one side of the middle of the processing machine tool 1, and a side sealing and cutting mechanism 20 provided on one side of one end of the processing machine tool 1. The side pre-compression mechanism 2 includes a base plate 201, a U-shaped frame 21 fixedly installed on the upper end of the base plate 201, a screw 22 rotatably installed in the middle of the U-shaped frame 21, one end of the screw 22 rotatably engaging with the middle of the base plate 201, a handwheel 23 fixedly connected to the upper end of the screw 22 through the top of the U-shaped frame 21, a slide plate 24 threadedly connected to the middle of the screw 22, a cylinder 25 fixedly installed on one end of the slide plate 24, and a connecting plate 26 fixedly installed on the other end of the slide plate 24. The moving clamp is connected to both sides of the middle part of the U-shaped frame 21. Multiple pulleys 27 are rotatably installed on both sides of the middle part of one end of the connecting plate 26. A transmission belt 28 is connected between every two pulleys 27. The side sealing and cutting mechanism 20 includes a side plate 29. A top plate 30 is fixedly installed on one side of the upper end of the side plate 29. A motor 31 is fixedly installed on one side of the upper end of the top plate 30. A transmission screw 32 is fixedly installed at the output end of the motor 31. The transmission screw 32 is rotatably installed in the middle part of the top plate 30. One end of the transmission screw 32 is rotatably clamped to a side heating die-cutting knife group 33. A slide rod 34 is fixedly installed above one side of the side heating die-cutting knife group 33. The upper end of the slide rod 34 is slidably clamped to one side of the middle part of the top plate 30. The side pre-pressing mechanism 2 and the side sealing and cutting mechanism 20 are located on the same horizontal line.

[0024] In this embodiment, the side pre-compression mechanism 2, through the combination of screw 22, slide plate 24, pulley 27, and transmission belt 28, can precisely adjust the pre-compression height and pressure, ensuring that the sides of the film are uniformly and stably compressed during transportation, avoiding film offset and wrinkles, and providing a regular substrate for subsequent sealing and cutting processes. The cooperation between pulley 27 and transmission belt 28 can not only realize continuous film transportation, but also make the film sides adhere in advance through the pre-compression action, reducing the risk of deformation during subsequent sealing and cutting. The side pre-compression mechanism 2 can drive the screw 22 structure through handwheel 23, supporting manual and rapid adjustment of the pre-compression height. It can adapt to films of different thicknesses and widths to meet the processing needs of products of various specifications. The design of the transmission screw 32 and slide bar 34 of the side sealing and cutting mechanism 20 makes the position adjustment of the blade group more flexible, and facilitates the adjustment of sealing and cutting parameters according to the packaging size, thereby improving the versatility of the equipment. At the same time, the side sealing and cutting mechanism 20 adopts the drive method of the motor 31 driving the transmission screw 32, and the slide bar 34 is used to guide the side heating die-cutting blade group 33, so that the side heating die-cutting blade group 33 can achieve precise vertical movement, ensuring the consistency of sealing position and depth, and effectively improving the sealing of the side seal and the flatness of the cut.

[0025] Example 2: As Figure 1 - Figure 3 As shown, a conveyor belt 11 is provided in the middle of the upper end of the machine tool 1, and a feeding box 12 is provided on one side of the other end of the machine tool 1. A guide roller 13 is provided in the middle of the feeding box 12. A height adjustment frame 16 is fixedly installed on the other side of the middle of the machine tool 1. A support frame 14 is provided in the middle of the height adjustment frame 16. A triangular plate 15 is fixedly installed on one side of the support frame 14. The triangular plate 15 is located above one end of the conveyor belt 11. A bracket 17 is provided on one side of the upper end of the machine tool 1. The bracket 17 is located in the middle of the side pre-pressing mechanism 2 and the side sealing and cutting mechanism 20. A screw 18 is threadedly connected to the middle of the bracket 17. The upper end of the screw 18 passes through the top of the bracket 17 and is fixedly installed with a... Handwheel 19 and guide rods 190 are fixedly installed on both sides of the middle of bracket 17. A fixing plate 192 is threadedly connected to the outer side of the middle of screw 18. The two ends of fixing plate 192 are slidably engaged with the outer side of guide rod 190. Cylinder 191 is fixedly installed on both sides of the middle of fixing plate 192. The two cylinders 191 are slidably engaged with both sides of the middle of the upper end of bracket 17. The output ends of the two cylinders 191 are fixedly connected with a lower pressure plate 193. A heating film cutter assembly 194 is fixedly installed at the lower end of the lower pressure plate 193. A load-bearing plate 195 is fixedly installed on the upper end of one side of the processing machine tool 1. The load-bearing plate 195 and the heating film cutter assembly 194 correspond to each other.

[0026] In this embodiment, the conveyor belt 11 is used to continuously transport disposable tableware materials, while the guide roller 13 of the feeding box 12 guides and tensions the film. The two work together to ensure stable feeding of the film during processing, avoiding deviation or slippage. The triangular plate 15 can fold the flat film into a tubular structure, providing a regular three-dimensional substrate for subsequent side sealing and filling. Its structural precision directly determines the consistency of the packaging bag's shape and reduces molding defects. The adjustment mechanism composed of the bracket 17, screw 18, and cylinder 191 can precisely control the height and pressing force of the heating film cutter group 194. The heating function ensures a firm film seal, while the die-cutting group achieves precise cutting, making the finished product cut flat and burr-free. When the lower pressure plate 193 presses down, the load-bearing plate 195 provides stable support, ensuring uniform force on the film during sealing and cutting, further improving the quality stability of sealing and cutting. The screw 18 can adjust the heating film cutter group 194 to adapt to films of different thicknesses and specifications, meeting the processing needs of multiple product categories.

[0027] Working principle:

[0028] like Figure 1 - Figure 5 As shown, during use, the rolled film is placed in the feeding box 12. Guided and tensioned by the guide roller 13, it enters the processing flow with stable tension, preventing film deviation or slack. When the film is conveyed to the area of ​​the triangular plate 15, because the triangular plate 15 is fixed to one side of the support frame 14 and located above one end of the conveyor belt 11, the flat film naturally folds to one side under the geometric guidance of the triangular plate 15. The folded side corresponds to the direction of the side pre-compression mechanism 2 and the side sealing and cutting mechanism 20, ultimately forming a semi-tubular structure with one edge overlapping and the other side open. At this time, one side of the film is the original film joint, which is seamlessly sealed. The disposable tableware to be packaged will enter the semi-tubular film along with the conveyor belt 11 and move together with the conveyor belt 11 and the semi-tubular film.

[0029] The semi-tubular film continues to be conveyed by the conveyor belt 11, reaching the side pre-compression mechanism 2. By rotating the screw 22 with the handwheel 23, the height of the slide plate 24 is adjusted, so that the pulley 27 and the transmission belt 28 uniformly pre-compress the overlapping sides of the film, ensuring that the side shape is regular and preparing for subsequent sealing and cutting. Continuing to move, it will reach below the heating film cutter assembly 194. Before that, the height of the fixing plate 192 can be adjusted by rotating the screw 18 with the handwheel 19, so that the heating film cutter assembly 194 is aligned with the load-bearing plate 195. The cylinder 191 drives the lower pressure plate 193 to press down. The heating film cutter assembly 194 first heats and seals one end of the film, and then cuts it, forming a bag-shaped substrate with one end sealed, one side edge overlapping, and the other end open. At this time, only one end is sealed and cut, and one side and the other end are still overlapping and unsealed. The bag-shaped substrate with the end sealed and cut continues to be conveyed. The pre-compressed bag-shaped substrate continues to be conveyed by the conveyor belt 11 and enters the side sealing and cutting mechanism 20. The motor 31 drives the transmission screw 32, which drives the side heating die-cutting knife group 33 to move vertically. The knife group first heats and seals the overlapping sides of the film, and then continues to move. At this time, only one end is unsealed. When the other unsealed end of the film passes the heating film cutting knife group 194, it will be sealed and cut off, thus completing the sealing and cutting of the disposable tableware. It is then conveyed by the conveyor belt 11 to the downstream sorting or boxing stage to complete the entire packaging process.
