The second hot melt block 1411 and the second traction wheel 1410 at both ends of the second traction belt 1412, the first traction belt 1407 and the second traction belt 1412 can cooperate with the traction bag type gourd film 301 to move left and right; the gourd film inflation heat sealing part 6 also includes an inflation tube 15, and the inflation tube mouth 1501 of the inflation tube 15 is arranged on the right between the first traction belt 1407 and the second traction belt 1412 of the gourd film inflation heat sealing part 6; the gourd bag tearing part 9 includes a first mechanical claw 904 and a second mechanical claw 905 distributed along the left and right, and the first mechanical claw 904 can move forward and backward relative to the second mechanical claw 905, and the first mechanical claw 904 can move to the left of the second mechanical claw 905. Function: (1) A conveyor belt extending left and right is provided on the base, a bag-type gourd film feeding part is provided on the right side of the conveyor belt, and a gourd film inflation heat sealing part, a material discharge working area, a gourd bag heat sealing part, and a gourd bag tearing part are provided above the conveyor belt, which are distributed from right to left in sequence; thus, the prefabricated gourd film roll can be placed on the bag-type gourd film feeding part, and the bag-type gourd film feeding part is used to continuously supply the bag-type gourd film to the conveyor belt, and finally, under the continuous drive of the conveyor belt, the bag-type gourd film passes through the gourd film to the left in sequence. The workstations include the inflation and heat sealing section, the discharge working area, the gourd bag heat sealing section, and the gourd bag tearing section. Among them, the gourd film inflation and heat sealing section inflates and heat seals the gourd film airway of the bag-type gourd film, so that the bag-type gourd film forms a bag with an open upper end. Then the operator puts the product into the bag-type gourd film through the bag opening in the discharge working area. Then the gourd bag heat sealing section heat seals the bag opening. Finally, the gourd bag tearing section tears the bag-type gourd film on both sides of the tear line to form a single bag.(2) The gourd film inflation heat sealing part and the gourd bag heat sealing part respectively include a heat sealing mechanism, and the heat sealing mechanism includes a first traction belt and a second traction belt distributed along the front and back, and a first hot melt block connected to both ends of the first traction belt, a first traction wheel, a second hot melt block connected to both ends of the second traction belt, and a second traction wheel. The first traction belt and the second traction belt can cooperate with the traction bag type gourd film to move left and right; thereby, the first traction wheel can be used to drive the first traction belt to rotate between the first hot melt block and the first traction wheel, and the second traction wheel can be used to drive the second traction belt to rotate between the second hot melt block and the second traction wheel, and then the rotating first traction belt and the second traction belt cooperate to pull the bag type gourd film to move to the left, and at the same time, the first hot melt block and the second hot melt block together perform heat sealing treatment on the bag type gourd film moving to the left, so that the heat sealing treatment function of the gourd film inflation heat sealing part and the gourd bag heat sealing part can be realized. (3) The gourd film inflation heat sealing part also includes an inflation tube, and the inflation tube port of the inflation tube is set on the right between the first traction belt and the second traction belt of the gourd film inflation heat sealing part; thereby, the gourd film airway of the bag-type gourd film can be first inserted into the inflation tube, and then the inflation tube port of the inflation tube blows air into the gourd film airway, so that the bubbles of the bag-type gourd film swell, and finally the heat sealing mechanism of the gourd film inflation heat sealing part heat seals the gourd film airway of the bag-type gourd film, so that the bag-type gourd film can be formed into a bag with an open upper end. (4) The tearing part of the gourd bag includes a first mechanical claw and a second mechanical claw distributed along the left and right sides. The first mechanical claw can move forward and backward relative to the second mechanical claw, and the first mechanical claw can move to the left of the second mechanical claw; so that when the bag-shaped gourd film reaches the tearing part of the gourd bag, the first mechanical claw and the second mechanical claw will respectively grasp the left and right sides of the tear line, and then the first mechanical claw moves forward and backward relative to the second mechanical claw, so that the tear line is torn, so that the bag-shaped gourd film on both sides of the tear line is separated, so that a single bag can be formed. From the above analysis, it can be seen that the present invention can realize automatic blowing and heat sealing of the gourd film airway, automatic heat sealing of the bag opening, and automatic tearing of the bag-shaped gourd film on both sides of the tear line. Therefore, compared with the existing technology, the present invention only requires the operator to put the product into the bag-shaped gourd film through the bag opening in the material discharge work area, without the operator having to participate in every process, thereby greatly improving the packaging work efficiency.

[0038] Specifically, the heat sealing mechanism 14 also includes a fixed plate 1401 and a movable plate 1402. The fixed plate 1401 is provided with a movable groove running through it from top to bottom. The movable plate 1402 is arranged in the movable groove so as to be movable back and forth. A first hot melt block 1406 and a first traction wheel 1405 are arranged at the bottom end of the fixed plate 1401. A second hot melt block 1411 and a second traction wheel 1410 are arranged at the bottom end of the movable plate 1402. The forward and backward movement of the movable plate 1402 can adjust the distance between the first traction belt 1407 and the second traction belt 1412. Function: Through the forward and backward movement of the movable plate, the second hot melt block 1411, the second traction wheel 1410, and the second traction belt 1412 can be driven to move back and forth, thereby facilitating the adjustment of the distance between the first traction belt 1407 and the second traction belt 1412, thereby facilitating the clamping and loosening of the bag-shaped gourd film.

[0039] Specifically, the first hot melt block 1406 is arranged to the right of the first traction wheel 1405, and the second hot melt block 1411 is arranged to the right of the second traction wheel 1410.

Function: By driving the cylinder, the moving plate 1402 can be driven to move forward and backward, so that the second gear 1404 can be engaged and separated with the first gear 1403. When engaged, the second gear 1404 and the first gear 1403 can rotate synchronously, thereby realizing the synchronous movement of the first traction belt 1407 and the second traction belt 1412.

[0040] Specifically, the first gear 1403 of the gourd film inflation heat sealing unit 6 and the gourd bag heat sealing unit 8 are both connected to the first motor 13 via the first transmission belt 12 and the first transmission wheel 1201. Function: Driven by the first motor, the first transmission belt 12 and the first transmission wheel 1201 work together to drive the first gear 1403 of the gourd film inflation heat sealing unit 6 and the gourd bag heat sealing unit 8 to rotate. An inflation tube 15 is disposed between the fixed plate 1401, the first traction belt 1407, and the second traction belt 1412 of the gourd film inflation heat sealing unit 6.

A spring 1408 is provided to the right between the first traction belt 1407 and the second traction belt 1412. The spring 1408 can cooperate with the first traction belt 1407 and the second traction belt 1412 to compress the bag-shaped gourd film 301. Function: By providing the spring, the gas can be sealed to prevent the injected gas from leaking to the outside, while also facilitating the heat sealing process of the heat sealing mechanism. The first hot melt block 1406 and the second hot melt block 1411 can heat-seal the bag-shaped gourd film 301 through the first traction belt 1407 and the second traction belt 1412, respectively. Function: The first and second traction belts can also conduct heat and have no thermal insulation effect. Non-insulating or highly thermally conductive materials can be selected, so that the first and second hot melt blocks can heat-seal the bag-shaped gourd film through the first and second traction belts, respectively. Of course, the first and second hot melt blocks can also heat-seal the bag-shaped gourd film through the portions exposed outside the traction belts. Preferably, since the height of the opening 303 of the bag-shaped gourd film 301 is lower than the height of the gourd film airway 302, to compensate for this height difference, the height of the gourd bag heat-seal portion 8 can be lower than the height of the gourd film inflation heat-seal portion 6. Of course, other methods are also possible. Preferably, the discharge workspace 7 is provided at the rear middle opening of the first housing 11, and a platform for placing items is provided in front of the first housing.

The function of the support frame 1004 is to rotate the screw rod 1005, causing it to move upward or downward relative to the base, thereby in turn driving the support frame 1004 and the conveyor belt 10 up and down. This allows the conveyor belt 10 to adjust to the height of bags of varying sizes. Preferably, the base can be configured as a chassis to better accommodate the screw rod and other components.

[0046] Specifically, the front and rear sides of the support frame 1004 are each provided with an upwardly extending support plate 1001. The conveyor belt 10 is disposed between the front and rear support plates 1001. The front and rear sides of the conveyor belt 10 are each provided with an upwardly extending baffle 1003. The front and rear baffles 1003 are respectively disposed on the inner sides of the front and rear support plates 1001. Adjustment rods 1002 are respectively provided on the front and rear support plates 1001. The front and rear adjustment rods 1002 can adjust the front and rear baffles 1003 closer together. Function: By moving the adjustment rods back and forth, the front and rear baffles 1003 can be adjusted closer or further apart, thereby adjusting the distance between the two baffles according to the size of different gourd bags.

[0047] In summary, the present invention aims to automate the packaging of cucurbit film bags. The cucurbit film bags are prefabricated before being installed in the machine, with tear lines formed between the bags. Therefore, the present invention can automatically heat-seal these cucurbit film bags into bags, automatically heat-seal the bags after the product is placed, and automatically tear open each bag to individually package the product.

[0048] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
