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.
[0017] Figures 1-4 The present invention relates to a hot cutting device for processing tote bags, comprising a frame 10, a cylinder 20, a worktable assembly 30, a heating and cutting mechanism 40, and a buffer assembly 50.
[0018] In this embodiment: The cylinder 20 is mounted on the frame 10 with its piston rod 11 facing downwards. The cylinder 20 is an adjustable stroke cylinder and includes a stroke adjustment mechanism. The stroke adjustment mechanism includes an adjusting nut 12 and a locking nut 13 located on the outside of the piston rod 11. By rotating the adjusting nut 12, the maximum stroke position of the piston rod 11 is changed, making the downward pressing process smoother. When approaching the limit position, the speed is slowed down to avoid uneven cutting edges caused by excessive impact force.
[0019] The workbench assembly 30 includes a workbench 31, a contour positioning block 32, and a collection box 33.
[0020] The workbench 31 is located at the bottom of the frame 10, and the contour positioning block 32 is located on the workbench 31 and is adapted to the contour pressing block 51 for precise positioning of the tote bag.
[0021] The collection box 33 is set on the workbench 31 and located on one side of the contour positioning block 32. The collection box 33 is used to collect the waste material cut off by the hot cutting knife 42 from the tote bag.
[0022] The heated cutting mechanism 40 includes a connecting plate assembly 41 and a hot cutting blade 42. The connecting plate assembly 41 includes a mounting plate 411, a heat dissipation column 412, a heating plate 413, a top plate 414, and a fixing column 415.
[0023] Mounting plate 411 is connected to piston rod 11. The upper end of heat dissipation column 412 is connected to mounting plate 411, and the lower end is connected to heating plate 413. Hot cutting blade 42 is mounted on heating plate 413 and connected to heating element. One end of fixing column 415 is connected to mounting plate 411, and the other end is connected to top plate 414. In this embodiment, the heating element is a heating tube embedded inside hot cutting blade 42. The heating tube is connected to a temperature controller, which is configured to control the temperature of hot cutting blade 42 within the range of 180 to 250°C.
[0024] The cushioning assembly 50 includes a contoured pressure block 51, a guide post 52, a cushioning plate 53, and a spring 54. The upper end of the guide post 52 is connected to the top plate 414, and the lower end is connected to the cushioning plate 53. The contoured pressure block 51 is positioned below the cushioning plate 53, and the spring 54 is sleeved on the guide post 52, with its two ends abutting against the top plate 414 and the cushioning plate 53, respectively. Through this structural design, this application integrates the heat-sealing and cutting processes into a single action, significantly improving production efficiency. The cushioning assembly 50 ensures uniform and appropriate clamping force, preventing bag deformation.
[0025] The buffer plate 53 has an opening 531, which is located above the collection box 33 and communicates with the entrance of the collection box 33. There are two contouring blocks 51, which are located between the buffer plate 53 and the collection box 33, and on both sides of the hot cutting blade 42.
[0026] The working process for this application is as follows: First, place the tote bag on the contour positioning block 32 of the workbench 31, start the cylinder 20, and the piston rod 11 drives the heating and cutting mechanism 40 to move downward. When the contouring block 51 contacts the contouring positioning block 32 and presses the tote bag, the spring 54 begins to compress, providing a buffering force to ensure that the tote bag is pressed evenly without deformation. As the piston rod 11 continues to descend, the hot cutting blade 42 maintains the set temperature under the control of the temperature controller, heat-sealing the bottom of the bag and cutting off the excess.
[0027] In this application, the heat sealing and cutting processes are integrated into one action, which significantly improves production efficiency. The design of the contouring block 51 and the contouring positioning block 32 provides precise positioning, and the buffer component 50 ensures uniform and moderate clamping force, prevents bag deformation, ensures neat cutting edges, high heat sealing strength, and stable product quality.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
