By turning on the auxiliary electric push rod 205, the pressure plate 206 can be driven to descend, so that the pressure plate 206 is pressed on the woven bag to press out the air in the woven bag.

[0066] Example 2:

[0067] Based on Example 1, in order to pull the woven bags onto the loading plate 201 when stacking them and prevent the woven bags from bending and wrinkling when moving and stacking, a material transfer structure is arranged on the material receiving structure for clamping the woven bags and transferring them to the material receiving position of the material receiving structure.

[0068] Among them, the material moving structure includes a U-shaped clamping strip 3 and a clamping plate 301 slidably installed inside the U-shaped clamping strip 3, a clamping electric push rod 302 arranged above the U-shaped clamping strip 3 for controlling the lifting and lowering of the clamping plate 301, the output end of the clamping electric push rod 302 passes through the U-shaped clamping strip 3 and is arranged above the clamping plate 301, and a driving component arranged on the U-shaped clamping strip 3 for driving the U-shaped clamping strip 3 to move. When one end of the woven bag moves into the U-shaped clamping strip 3 and is located under the clamping plate 301, the clamping electric push rod 302 is opened to control the clamping plate 301 to descend, so that the clamping plate 301 is pressed on one end of the woven bag.

[0069] Specifically, the driving assembly includes a fixed plate 303 and a fixed bar 306 arranged on the inner wall of the support frame 2, a screw rod 304 arranged on one side of the U-shaped clamping bar 3, the screw rod 304 is slidably installed inside the fixed plate 303, a screw stepper motor 305 arranged on one side of the fixed plate 303 for controlling the movement of the screw rod 304, the screw stepper motor 305 is threadedly sleeved on the screw rod 304, a guide rod 307 arranged between the fixed plate 303 and the fixed bar 306, and a linkage push rod 308 arranged below the U-shaped clamping bar 3 for guiding the moving direction of the U-shaped clamping bar 3. The linkage push rod 308 is slidably installed on the guide rod 307. When the screw stepper motor 305 is turned on, it drives the screw rod 304 to slide inside the fixed plate 303, so that the screw rod 304 drives the U-shaped clamping bar 3 to move. The moving U-shaped clamping bar 3 can drive the clamped woven bag to move, and pull the woven bag to the top of the loading plate 201.

[0070] Example 3:

[0071] On the basis of Example 2, in order to make the woven bags more flat and compact when stacked, a stretching structure for straightening the woven bag material is arranged on the material splicing structure.

[0072] Among them, the tensile structure includes a support plate 4 arranged on the support frame 2, a guide slide 401 slidably installed inside the support plate 4, a linkage slide rod 402 slidably installed inside the guide slide rod 401, a U-shaped clamp 403 arranged on one side of the linkage slide rod 402, a plywood 404 slidably installed inside the U-shaped clamp 403, a clamping electric push rod 405 arranged above the U-shaped clamp 403 for controlling the lifting and lowering of the plywood 404, the output end of the clamping electric push rod 405 passes through the U-shaped clamp 403 and is arranged above the plywood 404, and a linkage component arranged on the U-shaped clamp 403 for driving the U-shaped clamp 403 to move. By opening the clamping electric push rod 405, the plywood 404 can be driven to press on the side of the woven bag to clamp and fix the woven bag.

[0073] Specifically, the linkage assembly includes a U-shaped linkage rod 406 arranged on one side of the guide slide 401, an extrusion rod 407 arranged on the inner wall of the support frame 2, an inclined surface 408 set on the extrusion rod 407, a trapezoidal rod 409 arranged at one end of the linkage slide 402, the trapezoidal rod 409 contacts the inclined surface 408, a guide slide hole 410 is opened inside the extrusion rod 407, the U-shaped linkage rod 406 corresponds to the linkage push rod 308, the linkage slide 402 is slidably installed in the inclined surface 408, and the linkage push rod 308 is continuously moved. The U-shaped linkage rod 406 will be squeezed and moved. When the U-shaped linkage rod 406 moves, it can drive the guide slide 401 to move. The guide slide 401 drives the U-shaped clamping strip 2 403 to move through the linkage slide rod 402, and then the U-shaped clamping strip 2 403 drives the clamped woven bag to move. During the continuous movement of the linkage slide rods 402 on both sides, the trapezoidal rod 409 will be squeezed by the inclined surface 408, which will drive the two U-shaped clamping strips 2 403 to move away from each other, stretching the clamped woven bag to ensure that the woven bag remains flat when stacked.

[0074] Specifically, the linkage assembly also includes a spring 411 that is slidably sleeved on the linkage slide rod 402 and is used to drive the movement of the U-shaped clamp bar 2 403 for reset. The two ends of the spring 411 are respectively arranged between the guide slide 401 and the U-shaped clamp bar 2 403. During the movement of the U-shaped clamp bar 2 403, the spring 411 at the corresponding position will be compressed. When the trapezoidal rod 409 is out of contact with the inclined surface 408, the compressed spring 411 will push the U-shaped clamp bar 2 403 to move and reset.

[0075] Working principle:

[0076] By turning on the lifting control motor 203, the adjusting screw 202 can be driven to rotate. The rotating adjusting screw 202 can drive the material loading plate 201 to move by cooperating with the thread of the material loading plate 201. By controlling the rotation direction of the adjusting screw 202, the material loading plate 201 can be controlled to rise and fall. When stacking woven bags, the material loading plate 201 is first controlled to rise, and then the processed woven bags are transported by the conveyor belt 1. When one end of the woven bag moves into the U-shaped clamping strip 3 and is located under the clamping plate 301, the clamping electric push rod 302 is turned on to control the clamping plate 301 to descend, so that the clamping plate 301 is pressed At one end of the woven bag, the screw stepper motor 305 is turned on to drive the screw 304 to slide inside the fixed plate 303, so that the screw 304 drives the U-shaped clamp 3 to move. The moving U-shaped clamp 3 can drive the linkage push rod 308 to slide on the guide rod 307, thereby preventing the U-shaped clamp 3 from deviating. When the U-shaped clamp 3 moves, it can drive the clamped woven bag to move, pulling the woven bag above the loading plate 201, and at the same time moving the two sides of the woven bag to the inside of the two U-shaped clamps 403, and the middle position of the woven bag contacts the top of the loading plate 201 to prevent the middle of the woven bag from sinking.

[0077] When both sides of the woven bag are completely moved into the U-shaped clamping strip 2 403, the clamping electric push rod 1 302 is controlled to make the clamping plate 1 301 disengage from the clamping of the woven bag. At this time, the clamping electric push rod 2 405 can be opened to drive the clamping plate 2 404 to press on both sides of the woven bag to clamp both sides of the woven bag. The continuously moving linkage push rod 308 will contact the U-shaped linkage rod 406 and squeeze the U-shaped linkage rod 406 to make the U-shaped linkage rod 406 move. When the U-shaped linkage rod 406 moves, it can drive the guide slide 401 to move, and the guide slide 401 will move. The movable linkage slide bar 402 moves in the guide slide hole 410, and the linkage slide bar 402 can drive the U-shaped clamping strip 2 403 to move, thereby causing the U-shaped clamping strip 2 403 to drive the clamped woven bag to move. The linkage slide bar 402 will drive the trapezoidal rod 409 to move during the continuous movement, so that the trapezoidal rod 409 is squeezed by the inclined surface 408 and pulls the linkage slide bar 402 to slide inside the guide slide 401. At this time, the linkage slide bars 402 on both sides can drive the two U-shaped clamping strips 403 to move away from each other and compress the springs 411 at the corresponding positions, thereby clamping the bag. The woven bag is stretched to ensure that the woven bag remains flat when stacked, and then the continuously moving U-shaped clamp 2 403 is loosened from the woven bag, so that the woven bag falls completely to the middle above the material loading plate 201, and then the screw stepper motor 305 is controlled to drive the U-shaped clamp 1 3 to move and reset. The reset U-shaped clamp 1 3 will pull the U-shaped linkage rod 406 to move and reset through the linkage push rod 308, thereby driving the guide slide 401 to move and reset, and at the same time making the trapezoidal rod 409 out of contact with the inclined surface 408. At this time, the compressed spring 411 will push The U-shaped clamp bar 203 moves and resets, so that the U-shaped clamp bar 103 and the U-shaped clamp bar 203 return to their initial state, so that the woven bag can be repeatedly pulled and stacked. When stacking, the height of the material loading plate 201 can be adjusted according to the stacking height of the woven bag. By moving the position of the U-shaped clamp bar 103 and the screw rod 304, they are separated from the obstruction below the pressure plate 206. The auxiliary electric push rod 205 can be turned on to drive the pressure plate 206 to descend, so that the pressure plate 206 passes between the two U-shaped clamp bars 203 and presses on the woven bag to press out the air in the woven bag.
