Detailed implementation manners

[0010] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0011] Please refer to Figure 1-14, the present invention provides the following technical solutions: a new type of non-woven geocell welding machine, including a PLC controller 1, an ultrasonic welding machine 2, a human-machine interaction screen 3, an operation frame 4, and an operation platform 5. The operation platform 5 is arranged inside the operation frame body. The ultrasonic welding machines 2 are equidistantly arranged inside the operation frame 4 and are located above the operation platform 5. An inlet is arranged on the operation platform 5. An alternating device is arranged inside the operation frame 4. The alternating device includes a first pressing block 6, a second pressing block 7, a first cross beam 8, a second cross beam 9, a first horizontal linear module 10, a second horizontal linear module 11, a first vertical linear module 12, and a second vertical linear module 13. The first pressing blocks 6 are equidistantly connected to the first cross beam 8. The second pressing blocks 7 are equidistantly connected to the second cross beam 9. The first horizontal linear module 10 and the second horizontal linear module 11 are both connected to the inside of the operation frame 4 through brackets. The first vertical linear module 12 is connected to the driven part of the first horizontal linear module 10. The second vertical linear module 13 is connected to the driven part of the second horizontal linear module 11. The first cross beam 8 is connected to the driven part of the first vertical linear module 12. The second cross beam 9 is connected to the driven part of the second vertical linear module 13. The ultrasonic welding machines 2 are equidistantly arranged inside the operation frame 4 through a third vertical linear module 14. A third horizontal linear module 15 is arranged between the operation frame 4 and the operation platform 5. The inlet is connected to a feeding device 16. The first horizontal linear module 10, the second horizontal linear module 11, the third horizontal linear module 15, the first vertical linear module 12, the second vertical linear module 13, the third vertical linear module 14, and the feeding device 16 are all connected to the PLC controller 1 through wires. The feeding device 16 is used to move the cloth strips onto the operation platform 5. The third vertical linear module 14 is used to drive the ultrasonic welding machines 2 to move towards the operation platform 5.

[0012] With the above structure, by arranging an alternating device composed of the first / second pressing blocks 7, cross beams, horizontal / vertical linear modules inside the operation frame 4, and cooperating with the operation platform 5 and the feeding device 16 driven by the third horizontal linear module 15, precise positioning, alternating pressing, and continuous welding of multiple non-woven cloth strips are achieved. This structure enables the PLC controller 1 to uniformly dispatch each linear module, automatically complete the coordinated actions of cloth conveying, platform shifting, alternating pressing of the pressing blocks, and ultrasonic welding, ensuring uniform distribution of the welding points, improving the welding accuracy and production efficiency of the geocell, while reducing manual intervention and the risk of cloth offset caused by manual operation.

[0013] In this embodiment, an auxiliary pressing cylinder 17 is provided on the side wall of the third vertical linear module 14. The push rod of the auxiliary pressing cylinder 17 is connected to an auxiliary pressing block 18, and the auxiliary pressing cylinder 17 is connected to the plc controller 1 through a wire.

[0014] With the above structure, an auxiliary pressing cylinder 17 and an auxiliary pressing block 18 are added to the side wall of the third vertical linear module 14, which can pre-press the current layer of fabric before ultrasonic welding to enhance the adhesion between the fabric and the bottom layer. By precisely controlling the cylinder stroke through the plc controller 1, the auxiliary pressing block 18 can dynamically adjust the pressing force according to the fabric thickness or material, effectively avoiding the problem of false soldering caused by fabric loosening during the welding process, improving the firmness and consistency of the solder joints, and enhancing the adaptability of the equipment to non-woven fabrics of different specifications.

[0015] In this embodiment, the first pressing block 6 and the second pressing block 7 are arranged alternately.

[0016] With the above structure, the alternate arrangement of the first pressing block 6 and the second pressing block 7 enables the welding areas of adjacent layers of fabric to be supported by different pressing blocks respectively, avoiding fabric wrinkles or displacements that may be caused by a single pressing block during the displacement process. This layout optimizes the movement path of the pressing block, shortens the action cycle of alternate pressing, improves the operating efficiency of the equipment while ensuring the welding quality, and realizes the efficient switching of continuous welding of multiple layers of fabric.

[0017] In this embodiment, a temporary storage groove 19 is provided in the working platform. An elevating cylinder 20 is provided in the temporary storage groove 19. The push rod of the elevating cylinder 20 is connected to a baffle 21, and the elevating cylinder is connected to the plc controller 1 through a wire.

[0018] With the above structure, a temporary storage groove 19 and an elevating baffle 21 are provided in the working platform 5. By controlling the baffle 21 to descend with the number of welding layers through the plc, the temporary storage and layer positioning of the welded fabric are realized. This design not only creates space for the subsequent feeding and welding of the fabric to ensure production continuity, but also prevents the offset of multiple layers of fabric during stacking through the precise positioning of the baffle 21, keeping the finished product in a neatly stacked state, and enhancing the overall coordination of the production line and the stability of product quality.

[0019] Working principle: The distance is described using three strips of cloth (the bottom layer sequential strip, the first sequential strip, and the second sequential strip).

[0020] 1. Feeding stage of the bottom layer sequential strip The feeding device 16 transports the non-woven fabric strip to the working platform 5. The bottom layer sequential strip is located on the push plate, and the first pressing block 6 and the second pressing block 7 are located above the bottom layer sequential strip.

[0021] 2. Feeding of the first sequential strip Platform movement: The third horizontal linear module 15 drives the working platform 5 to move longitudinally by one grid distance; Feeding of new cloth strips: The feeding device 16 conveys the cloth strips in the first order to the working platform 5 and tightens both ends simultaneously.

[0022] 3. First displacement operation The second horizontal linear module 11 drives the second crossbeam 9 to move horizontally, so that the second pressing block 7 moves out from between the bottom-layer sequential cloth strips and the cloth strips in the first order. The second vertical linear module 13 drives the second crossbeam 9 to rise, and the second horizontal linear module 11 moves the second pressing block 7 above the cloth strips in the first order.

[0023] 4. Welding operation of the cloth strips in the first order The auxiliary pressing cylinder 17 pushes the auxiliary pressing block 18 downward to press the cloth strips in the first order. The third vertical linear module 14 drives the ultrasonic welding machine 2 to move downward, and the welding head abuts against the upper surface of the first pressing block 6 to complete the welding of the bottom-layer sequential cloth strips and the cloth strips in the first order. After the welding is completed, the baffle 21 descends by the thickness of one cloth strip.

[0024] 5. Second displacement operation The ultrasonic welding head lifts and disengages. The first horizontal linear module 10 drives the first crossbeam 8 to move horizontally, so that the first pressing block 6 moves out from between the bottom-layer sequential cloth strips and the cloth strips in the first order. The first vertical linear module 12 drives the first crossbeam 8 to rise, and the first horizontal linear module 10 moves the first pressing block 6 above the cloth strips in the first order.

[0025] 6. Feeding of the cloth strips in the second order Platform movement: The third horizontal linear module 15 drives the working platform 5 to move longitudinally by one grid distance; Feeding of new cloth strips: The feeding device 16 conveys the cloth strips in the second order to the working platform 5 and tightens both ends simultaneously.

[0026] 7. Second welding operation The auxiliary pressing cylinder 17 pushes the auxiliary pressing block 18 downward to press the cloth strips in the second order. The third vertical linear module 14 drives the ultrasonic welding machine 2 to move downward, and the welding head abuts against the upper surface of the second pressing block 7 to complete the welding of the cloth strips in the first order and the cloth strips in the second order. After the welding is completed, the baffle 21 descends by the thickness of one cloth strip.

[0027] Third displacement operation The ultrasonic welding head lifts and disengages. The second horizontal linear module 11 drives the second crossbeam 9 to move horizontally, so that the second pressing block 7 moves out from between the cloth strips in the first order and the cloth strips in the second order. The second vertical linear module 13 drives the second crossbeam 9 to rise, and the second horizontal linear module 11 moves the second pressing block 7 above the cloth strips in the second order.

[0028] Repeat the cyclic steps 2-7 to achieve continuous welding of the cloth strips.
