[0033] The above design can continuously convey the plastic bags to the top block 18 by providing the conveying component 3, so as to cooperate with the sealing component 2 for sealing, reduce the downtime for loading the materials, and thus improve the processing efficiency.

[0034] Specifically, please refer to Figures 1 to 3 The conveying assembly 3 includes a conveyor belt 31, a roller 32 and a motor 33. The bottom wall of the groove 14 is provided with an inwardly recessed mounting groove 16. The roller 32 is symmetrically arranged in the mounting groove 16 front and back. The conveyor belt 31 is connected to the roller 32. The left and right ends of the roller 32 are symmetrically provided with rotating shafts 321. The mounting groove 16 is provided with a rotating hole 161 that cooperates with the rotating shaft 321. The rotating shaft 321 extends into the rotating hole 161 and is rotatably connected to the rotating hole 161. The workbench 1 is provided with a mounting bin 17. The motor 33 is installed in the mounting bin 17. The output end of the motor 33 is fixedly connected to one of the rotating shafts 321. By arranging the conveyor belt 31, the rotating roller and the motor 33, the conveyor belt 31 can be driven by the motor 33 to transport plastic bags, thereby realizing loading.

[0035] Please pay attention to Figures 1 to 6The through groove 15 is also slidably connected with a limit rod 4, and the upper end surface of the limit rod 4 is provided with a guide groove 41, and the limit rod 4 is slidably connected to the through groove 15 through the guide groove 41, and a limit member 5 is installed on the rear end surface of the limit rod 4. By setting the limit rod 4 and the limit member 5, it is possible to ensure that the plastic bag will not be offset during the movement process through the limit rod 4, and it can be adjusted according to the length of the plastic bag. The limit member 5 includes a first handle 51 and a threaded rod 52. The rear end surface of the limit rod 4 is provided with a threaded hole 42, and the threaded hole 42 is connected to the guide groove 41. The threaded rod 52 is threadedly connected to the guide groove 41, and the first handle 51 is installed on the rear end surface of the threaded rod 52. By setting the first handle 51 and the threaded rod 52, the threaded rod 52 can be rotated to make the threaded rod 52 abut against the rear end surface of the workbench 1, so that the guide groove 41 is matched to be stuck in the through groove 15 to prevent the limit rod 4 from moving after the adjusted position.

[0036] Please pay attention to Figure 1 , Figure 2 , Figure 4 The front end surface of the top block 18 is installed with an inclined platform 181. By setting the inclined platform 181, when conveying the plastic bag, the opening of the plastic bag can be conveniently conveyed to the top block 18. The sealing component 2 includes a cylinder 21 and a heating plate 22. The cylinder 21 is installed on the upper end surface of the top plate 12. The output end of the cylinder 21 penetrates downward through the top plate 12. The heating plate 22 is installed at the output end of the cylinder 21. By setting the cylinder 21 and the heating plate 22, the heating plate 22 can be pushed downward by the cylinder 21, so that the heating plate 22 contacts the plastic bag and seals the plastic bag with hot pressing.

[0037] The specific operation mode of the embodiment 1 of the utility model is as follows:

[0038] When in use, press the switch to make the heating plate 22 self-heating, turn the first handle 51 counterclockwise to loosen the threaded rod 52, then slide the limit rod 4 to adjust to the required position, then turn the first handle 51 clockwise to make the threaded rod 52 clamp the limit rod 4 again, further put the plastic bag on the conveyor belt, so that the plastic bag is located at the upper end of the inclined platform 181, then press the switch to start the motor 33, the motor 33 drives the roller 32 to rotate, and drives the conveyor belt 31 to transport the plastic bag through the roller 32. When the plastic bag is transported to the top block 18, turn off the motor 33 and start the cylinder 21, so that the cylinder 21 pushes the heating plate 22 to seal the plastic bag, then turn off the cylinder 21, and start the motor 33 again, so that the sealed plastic bag is sent out of the workbench 1 through the through groove 15. At the same time, when the previous plastic bag is sealed, the next plastic bag is placed on the conveyor belt 31 and located at the upper end surface of the inclined platform 181.

[0039] It should be noted that the above design can also be equipped with a controller to control the motor 33 and the cylinder 21 so that they can automatically transport and seal the plastic bags.

[0040] Example 2

[0041] Please pay attention to Figures 1 to 4 The difference between Example 2 and Example 1 is that the limiting member 5 includes a fixing pin 53, a spring 54 and a slider 55. The rear end face of the limiting rod 4 is provided with a mounting hole 43, and the mounting hole 43 is connected to the guide groove 41. The fixing pin 53 is arranged in the mounting hole 43, and the mounting hole 43 is symmetrically provided with a slide groove 431. The slider 55 is symmetrically installed on the outer wall of the fixing pin 53 and is slidably connected to the slide groove 431. The spring 54 is arranged in the slide groove 431, and the two ends of the spring 54 are respectively fixedly connected to the slide groove 431 and the slider 55.

[0042] The above-mentioned design, by setting a fixing pin 53, a slider 55, a slide groove 431 and a spring 54, can support the slider 55 through the spring 54, so that the slider 55 supports the fixing pin 53, and the fixing pin 53 cooperates with the guide groove 41 to clamp the limit rod 4 in the guide groove 41 for fixation. When unlocking, it is only necessary to pull the fixing pin 53 to unlock, thereby being able to quickly unlock the limit rod 4 and improving the adjustment efficiency. In order to facilitate pulling out the fixing pin 53, a second handle 531 is set, and the rear end face of the fixing pin 53 is installed with the second handle 531. By setting the second handle 531, it is convenient to pull the fixing pin 53.

[0043] The specific operation method of the second embodiment of the present utility model is as follows:

[0044] When unlocking, the fixing pin 53 is pulled out backwards, and the fixing pin 53 drives the slider 55 to slide in the slide groove 431 and compress the spring 54. When the fixing pin 53 is separated from the rear end surface of the workbench 1, the limit rod 4 is unlocked and moved. When it is adjusted to a suitable position, the second handle 531 is released. At this time, the spring 54 rebounds and pushes the slider 55, so that the fixing pin 53 is stuck to the limit rod 4 again.

[0045] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
