[0021] Beneficial effects of the present invention:

[0022] 1. The original textile bag cloth on the cloth roll can be passed through the guide roller and passed through the pressing mechanism. The end of the original textile bag cloth can be clamped by the pulling clamping component. Then, the original textile bag cloth is stretched for a certain distance under the action of the lifting and lowering motion module. When stretched to a suitable distance, the two sets of heat-sealing knives are driven to move closer to each other by the bidirectional motion module until the two sets of heat-sealing knives clamp the original textile bag cloth, thereby heat-sealing the end of the original textile bag cloth. After the heat sealing is completed, the heat-sealing knife is away from the original textile bag cloth, and the lifting mechanism continues to drive the original textile bag cloth to stretch to the required distance. Then, the original textile bag cloth is pressed down by the pressing component, and then the original textile bag cloth is cut off by the cutting component. At this time, a textile bag with a bottom seal and an opening on the top is formed. When the traction clamping component releases the textile bag, the textile bag falls under the action of gravity. The above structure can realize automatic sealing of the textile bag, thereby reducing manpower and improving production efficiency. When the original cloth of the textile bag is heat-sealed, the traction mechanism can stretch the original cloth of the textile bag to make it in a taut state, which helps the heat-sealing knife to heat and press evenly, thereby improving the quality of heat sealing and the sealing of the textile bag, preventing air leakage or material leakage of the textile bag, and the taut original cloth can also reduce wrinkles and gaps, avoid irregular seals during the heat-sealing process, and improve the beauty and consistency of the seal. Furthermore, tightening the woven bag during heat sealing can make the heat-sealing lines more tightly integrated, increase the mechanical strength of the seal, and reduce the risk of rupture at the seal due to uneven force.

[0023] 2. The power generation component is used to realize power transmission between the lifting and lowering motion module and the bidirectional motion module. That is, when the traction and clamping component clamps the original fabric of the textile bag and drives the original fabric of the textile bag to move a certain distance through the lifting and lowering motion module, the lifting and lowering motion platform descends. At this time, under the cooperation of the rack and the ratchet transmission gear, the reciprocating screw A and the reciprocating screw B rotate, and the two sets of heat-sealing knives move close to each other. When the traction and clamping component moves to the predetermined position, the two sets of heat-sealing knives also heat-seal the original fabric of the textile bag. When the heat sealing is completed, the lifting and lowering motion module is closed. When the module continues to drive the textile bag original cloth to descend, under the characteristics of the reciprocating screw, the two sets of heat sealing knives begin to move away from each other to avoid fixing the textile bag original cloth, and when the lifting platform in the lifting motion module moves upward, under the action of the ratchet transmission gear, the reciprocating screw A and the reciprocating screw B do not work, so that the traction and clamping parts can smoothly pass through the heat sealing mechanism. This structural design allows the heat sealing mechanism and the traction mechanism to work together to improve work efficiency, and can reduce the number of driving sources, making the programming of the device control simpler and the failure rate lower.

[0044] See also Figure 4 , Figure 5 In this embodiment, the pressing component 301 includes a fixed pressing platform 303, a moving pressing platform 304, and an electric telescopic cylinder B305. Two groups of fixed pressing platforms 303 are fixedly connected to the bottom of the guide roller member 101 on the device frame 100. The two groups of fixed pressing platforms 303 are respectively close to the two sides of the textile bag original cloth 700. The corresponding fixed pressing platforms 303 on the device frame 100 are also fixedly connected to the sliding column A306. The sliding column A306 is slidably connected to the moving frame 307.

The piston end of the electric telescopic cylinder B305 is fixedly connected to the moving frame 307. The textile bag original cloth 700 passes between the fixed press platform 303 and the moving press platform 304. When the textile bag original cloth 700 needs to be fixed, the electric telescopic cylinder B305 can drive the moving press platform 304 to move closer to the fixed press platform 303 until the moving press platform 304 presses the textile belt original cloth down onto the fixed press platform 303.

[0045] In addition, the cutting component 302 includes a cutting frame 308, a transmission screw A309, a motor A310 and a laser cutting head 311.

At this time, the moving platform drives the laser cutting head 311 to move in a straight line, and the textile bag original cloth 700 is cut by the laser cutting head 311. Laser cutting is used here to make the cutting edge neat and smooth, without burrs and fluffing, and no further processing of the edge is required.

[0047] See also Figure 6 In this embodiment, the lifting motion module 401 also includes a transmission screw B404, a motor B405 and a sliding column B406, that is, the sliding column B406 is fixedly connected to the device frame 100, the lifting motion platform 403 is slidably connected to the sliding column B406, the lifting motion platform 403 is threadedly connected with the transmission screw B404, and the device frame 100 is fixedly connected with the motor B405.

[0048] In addition, the traction and clamping component 402 includes a connecting arm 407, a component frame 408, a clamping plate 409 and a clamping and loosening control component 410. The connecting arm 407 is fixedly connected to the lifting and moving platform 403, and the end of the connecting arm 407 is fixedly connected to the component frame 408. Two groups of clamping plates 409 are slidably connected to the component frame 408. The clamping plates 409 correspond to the area between the two groups of fixed pressure platforms 303. The matching clamping plates 409 on the component frame 408 are provided with a clamping and loosening control component. The clamping and loosening control component can realize the two groups of clamping plates 409 to move away from or close to each other, thereby realizing the clamping work of the clamping plates 409 on the textile bag original cloth 700.

[0049] See also Figure 7 Specifically, the clamping and loosening control assembly includes a spring 411, an electromagnet 412 and an adsorption plate 413.

At this time, the two groups of moving plates 415 can drive the clamping plates 409 to move until the two groups of clamping plates 409 clamp the textile bag original cloth 700 and the spring 411 is stretched. When it is necessary to release the textile bag original cloth 700, the electromagnet 412 is directly powered off. At this time, under the elastic force of the spring 411, the two groups of clamping plates 409 quickly move away.

[0050] See also Figure 1 , Figure 8Furthermore, a heat sealing mechanism 500 is further provided on the device frame 100, and the heat sealing mechanism 500 includes a heat sealing knife 501 and a bidirectional motion module 502, that is, the bidirectional motion module 502 includes a linear motion table 503, a reciprocating screw A504, a reciprocating screw B505, and a sliding column C506.

Rod B505, the reciprocating screw A504 and the end of the reciprocating screw B505 are fixedly connected by a transmission shaft. When power is provided to the reciprocating screw A504 or the reciprocating screw B505, the two groups of linear motion tables 503 can move away from or towards each other. Of course, a heat sealing knife 501 is also fixedly connected to each group of linear motion tables 503. The traction mechanism 400 can pull the textile bag original cloth 700 through the area between the two groups of heat sealing knives 501. When the textile bag original cloth 700 needs to be heat-sealed, the textile bag original cloth 700 can be clamped by the two groups of heat sealing knives 501 to complete the heat sealing work.

[0051] In general, the original textile bag cloth 700 on the cloth roll can be passed through the guide roller 101 and inserted into the pressing mechanism 300, and the end of the original textile bag cloth 700 can be clamped by the traction clamping component 402, and then the original textile bag cloth 700 is stretched for a distance under the action of the lifting and lowering motion module 401. After being stretched to a suitable distance, the two sets of heat sealing knives 501 are driven to move closer to each other through the two-way motion module 502 until the two sets of heat sealing knives 501 clamp the original textile bag cloth 700, thereby sealing the original textile bag cloth 700. The ends of the original bag cloth 700 are heat-sealed. After the heat sealing is completed, the heat-sealing knife 501 moves away from the original textile bag cloth 700, and the original textile bag cloth 700 continues to be stretched to the required distance through the lifting mechanism. Then, the original textile bag cloth 700 is pressed down by the pressing component 301, and then the original textile bag cloth 700 is cut off by the cutting component 302. At this time, a textile bag with a sealed bottom and an opening on the top is formed. When the traction clamping component 402 releases the textile bag, the textile bag falls under the action of gravity.

[0052] See also Figure 2 To optimize it, the reciprocating screw A504 and the lifting platform 403 can realize power transmission through the power generation component 600, that is, when the lifting platform 403 performs lifting motion, power can be generated by the power generation component 600 and transmitted to the reciprocating screw A504, so that the two groups of linear motion platforms 503 move away from or towards each other.

[0053] See also Figure 8 , Fig. 9 , Fig.10In this embodiment, the power generating assembly 600 includes a rack 601, a worm 602, a worm wheel 603, and a ratchet transmission gear 604. The end of the reciprocating screw is fixedly connected to a power input shaft 605, and a worm wheel 603 is fixedly connected to the power input shaft 605. A worm 602 is rotatably connected to the matching worm wheel 603 on the device frame 100. The worm 602 is meshed with the worm wheel 603. A ratchet transmission gear 604 is provided at one end of the worm 602. A rack 601 is fixedly connected to the matching ratchet transmission gear 604 on the lifting platform 403.

[0054] When the lifting platform 403 moves downward, the worm 602 drives the worm wheel 603 under the cooperation of the rack 601 and the ratchet transmission gear 604, so that the reciprocating screw A504 rotates, and the heat sealing mechanism 500 starts to work.

[0055] When the lifting platform 403 moves upward, under the cooperation of the rack 601 and the ratchet transmission gear 604, the worm 602 does not drive the worm wheel 603 to rotate, and the reciprocating screw does not rotate, so that the heat sealing mechanism 500 does not work.

[0056] In summary, when the traction clamping component 402 clamps the textile bag original fabric 700 and drives the textile bag original fabric 700 to move a certain distance through the lifting and moving module 401, the lifting and moving platform 403 descends. At this time, under the cooperation of the rack 601 and the ratchet transmission gear 604, the reciprocating screw A504 and the reciprocating screw B505 rotate, and the two sets of heat sealing knives 501 move close to each other. When the traction clamping component 402 moves to the predetermined position, the two sets of heat sealing knives 501 also just close to the textile bag original fabric. 700 is heat-sealed, and when the heat-sealing is completed and the lifting motion module 401 continues to drive the textile bag original cloth 700 to descend, under the characteristics of the reciprocating screw, the two sets of heat-sealing knives 501 begin to move away from each other to avoid fixing the textile bag original cloth 700, and when the lifting motion platform 403 in the lifting motion module 401 moves upward, under the action of the ratchet transmission gear 604, the reciprocating screw A504 and the reciprocating screw B505 do not work, so that the traction and clamping component 402 can smoothly pass through the heat-sealing mechanism 500.

[0057] Furthermore, the ratchet transmission gear 604 includes an inner rotating ratchet disc 606, an outer rotating disc 607, a toothed ring 608, a pawl 609, and an elastic member 610. The inner rotating ratchet disc 606 is provided inside the outer rotating disc 607, and the inner rotating ratchet disc is provided with a plurality of groups of ratchets. The outer wall of the outer rotating disc 607 is fixedly connected with a toothed ring 608, and the toothed ring 608 matches the rack 601. The inner matching ratchet of the outer rotating disc 607 is rotatably connected with a pawl 609, and the pawl 609 conflicts with the ratchet. The matching ratchet 609 inside the outer rotating disc 607 is also fixedly connected with the outer wall of the outer rotating disc 607. An elastic member 610 is fixedly connected, and the elastic member 610 abuts against the pawl 609. A wheel axle 611 is splined on the inner rotating ratchet disk 606. Both ends of the wheel axle 611 pass through the outer rotating disk 607 respectively. The wheel axle 611 is fixedly connected to the worm 602. In this way, when the rack 601 moves downward and the gear ring 608 rotates, the outer rotating disk 607 can rotate. At this time, the pawl 609 pushes the inner rotating ratchet disk 606, so that the inner rotating ratchet disk 606 also rotates, and the wheel axle 611 drives the worm 602 to rotate.

[0058] When the rack 601 moves upward, the gear ring 608 rotates, and the outer rotating disk 607 also rotates. At this time, the pawl 609 cannot push the inner rotating ratchet disk 606, so the wheel shaft 611 cannot drive the worm 602 to rotate.

[0059] In addition, to facilitate the maintenance of the ratchet transmission gear 604, the outer rotating disk 607 includes an outer shell A612 and an outer shell B613. The outer shell A612 is fixedly connected with a bolt 614, and the outer shell B613 is provided with a hole corresponding to the bolt 614. After the outer shell A612 and the outer shell B613 are buckled together, the bolt 614 passes through the hole, and the end of the bolt 614 is threadedly connected with a nut 615, and the gear ring 608 is fixedly connected to the outer shell A612.
