[0017] The woven bag drawing device of this utility model has the following advantages compared with the prior art:

[0018] 1. By providing annular grooves on both sides of the positioning ring and fitting at least five positioning rings onto the outside of the first rotating roller, the positioning rings position the plastic filaments, thereby separating the plastic filaments from each other and preventing adhesion between the plastic filaments when they are squeezed and stretched. This also achieves positioning of multiple plastic filaments, improving processing efficiency. By providing adjustment grooves on the adjustment blocks and embedding the positioning rings into the adjustment grooves, and by connecting the adjustment mechanism to at least five adjustment blocks simultaneously, the adjustment mechanism drives the adjustment blocks and positioning rings to move synchronously, thereby adjusting the distance between multiple positioning rings.

[0019] 2. By embedding the ball bearings into the groove of the connecting seat, the first limiting cover, and the annular groove of the positioning ring respectively, when the positioning ring rotates, it drives the ball bearings to rotate in the groove of the connecting seat and the annular groove of the positioning ring. This allows the adjusting block to move synchronously with the positioning ring through the two connecting protrusions and the two ball bearings, thereby enabling the distance between multiple positioning rings to be adjusted by moving multiple adjusting blocks.

[0020] 3. By mounting the first gear on one end of the first rotating roller and the second gear on one end of the second rotating roller, with the second gear meshing with the first gear, the first gear causes the first rotating roller and the second rotating roller to rotate in opposite directions through the second gear, thereby enabling the first rotating roller and the second rotating roller to compress and stretch the plastic filament.

[0021] 4. By connecting the first output shaft of the motor to one end of the first rotating roller, the motor drives the first output shaft to rotate the first rotating roller, thereby enabling the first motor to provide power for the first rotating roller and the second rotating roller to rotate in opposite directions through the first gear and the second gear.

[0022] 5. By fitting two second limiting covers onto both ends of the first rotating roller and positioning the two second limiting covers on both sides of the positioning ring, the two second limiting covers limit the positioning ring, thereby enabling the positioning ring to move between the two second limiting covers.

[0023] 6. By fitting the rubber sleeve onto the outside of the second rotating roller and abutting it against at least five positioning rings, frictional wear caused by relative movement between the second rotating roller and the positioning rings is avoided, thereby extending the service life of the second rotating roller and the positioning rings. At the same time, it can also enhance the extrusion and stretching effect of the second rotating roller and the first rotating roller on the plastic filament, further improving the product user experience.

[0024] 7. By fixing the first moving block, the second moving block, and the third moving block to the corresponding adjusting block, and connecting the pitch-changing mechanism to the first moving block, the second moving block, and the third moving block, the pitch-changing mechanism drives the adjusting block to move synchronously through the first moving block, the second moving block, and the third moving block, thereby adjusting the distance between multiple positioning rings through the pitch-changing mechanism.

[0025] 8. By rotatably connecting one end of each of the two second support rods to one end of each of the two first support rods, and rotatably connecting one end of each of the two third support rods to the other end of each of the two second support rods, and rotatably connecting the other ends of the two third support rods, the third support rods drive the second support rods to move laterally around the first support rods as the center, thereby enabling the third moving block to drive the second moving block to move laterally around the first moving block as the center, thus adjusting the distance between multiple positioning rings and making the distance between multiple limiting blocks equal.

[0026] 9. By fixing the guide rail to the second fixed plate and allowing the guide rail to pass through the first moving block, the second moving block, and the third moving block, the first moving block, the second moving block, and the third moving block can slide laterally on the guide rail, thereby preventing the first moving block, the second moving block, and the third moving block from shifting position during movement, thus improving the user experience of the product.

[0027] 10. By connecting the second output shaft of the cylinder to the side wall of a third moving block, the cylinder drives the third moving block to move, thereby enabling the third moving block to drive the first moving block, the second moving block, and another third moving block to move through the first support rod, the second support rod, and the third support rod.

Detailed Implementation

[0035] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0036] A woven bag drawing device, such as Figures 1 to 5 As shown, the woven bag drawing device includes: a base plate 100, a cutting mechanism 200, and a drawing mechanism 300; the cutting mechanism 200 and the drawing mechanism 300 are mounted on the base plate 100; the cutting mechanism 200 is equipped with a cutting blade and a rotating rod; the drawing mechanism 300 includes: a mounting plate 301, a first rotating roller 302, a positioning ring 303, an adjusting block 304, an adjusting mechanism 305, and a second rotating roller 306; the two mounting plates 301 are fixed on the base plate 100, and there is a gap between the two mounting plates 301; the two ends of the first rotating roller 302 are rotatably connected to the two mounting plates 301 respectively; the positioning ring 303... Annular grooves are provided on both sides, and at least five positioning rings 303 are fitted on the outside of the first rotating roller 302; the adjusting block 304 is provided with an adjusting groove, and at least five positioning rings 303 are respectively arranged opposite to at least five adjusting blocks 304, with the positioning rings 303 embedded in the adjusting groove; the adjusting mechanism 305 is mounted on the base plate 100, and the adjusting mechanism 305 is simultaneously connected to at least five adjusting blocks 304, and the adjusting mechanism 305 is located below the first rotating roller 302; the two ends of the second rotating roller 306 are respectively rotatably connected to two mounting plates 301, and the second rotating roller 306 is located above the first rotating roller 302.

[0037] After the plastic undergoes melting and extrusion molding, a plastic film is formed. A cutting mechanism 200 and a wire drawing mechanism 300 are mounted on the base plate 100 to support them. The cutting mechanism 200 contains a cutting blade and a rotating rod, allowing the cutting blade to cut the plastic film into plastic filaments. Two mounting plates 301 are fixed to the base plate 100 with a gap between them, providing support for the base plate 100. The first rotating roller 3... The two ends of 02 are rotatably connected to two mounting plates 301, so that the two mounting plates 301 support the first rotating roller 302, thereby enabling the first rotating roller 302 to rotate between the two mounting plates 301; by providing annular grooves on both sides of the positioning ring 303, and fitting at least five positioning rings 303 onto the outside of the first rotating roller 302, the positioning rings 303 position the plastic filaments, thereby separating the plastic filaments from each other, thus avoiding the phenomenon of adhesion between plastic filaments when squeezing and stretching them, and also enabling simultaneous operation of multiple... The plastic filaments are positioned to improve processing efficiency. By providing adjustment grooves to the adjusting block 304, at least five positioning rings 303 are respectively positioned opposite to at least five adjusting blocks 304, and the positioning rings 303 are embedded in the adjustment grooves. This allows the adjusting block 304 to drive the positioning rings 303 to move synchronously, thereby adjusting the distance between the positioning rings 303 through the adjusting block 304. The adjusting mechanism 305 is mounted on the base plate 100 and simultaneously connected to at least one adjusting block 304, with the adjusting mechanism 305 positioned on the first rotating roller 302. Below, the adjusting mechanism 305 drives the adjusting block 304 to move; by rotatably connecting the two ends of the second rotating roller 306 to the two mounting plates 301 respectively, the two mounting plates 301 support the second rotating roller 306, thereby enabling the second rotating roller 306 to rotate between the two mounting plates 301; by placing the second rotating roller 306 above the first rotating roller 302, the rotation of the first rotating roller 302 drives the second rotating roller 306 to rotate, thereby enabling the first rotating roller 302 and the second rotating roller 306 to extrude and stretch the plastic filament.

[0038] In the actual use of the product, the plastic film is first cut into multiple plastic filaments by the cutting mechanism 200. Then, the adjusting mechanism 305 drives the adjusting block 304 and the positioning ring 303 to move synchronously, thereby adjusting the spacing between the multiple positioning rings 303. Then, each plastic filament is positioned in the interval between two positioning rings 303. Then, the first rotating roller 302 and the second rotating roller 306 are rotated, thereby squeezing and stretching the plastic filaments through the first rotating roller 302 and the second rotating roller 306.

[0039] By employing the above structure, the positioning rings 303 are provided with annular grooves on both sides, and at least five positioning rings 303 are fitted onto the outside of the first rotating roller 302. This allows the positioning rings 303 to position the plastic filaments, thereby separating the plastic filaments from each other and preventing adhesion between them during the extrusion and stretching of the plastic filaments. Simultaneously, multiple plastic filaments are positioned to improve processing efficiency. The adjusting block 304 is provided with an adjusting groove, and the positioning rings 303 are embedded in the adjusting groove. The adjusting mechanism 305 is simultaneously connected to at least five adjusting blocks 304, enabling the adjusting mechanism 305 to drive the adjusting blocks 304 and positioning rings 303 to move synchronously. This allows the adjusting mechanism 305 to adjust the distance between the multiple positioning rings 303. The second rotating roller 306 is positioned above the first rotating roller 302, allowing the first rotating roller 302 and the second rotating roller 306 to extrude and stretch the plastic filaments. This allows the adjusting mechanism 305 to adjust the width of the extruded plastic filaments.

[0040] Specifically, the structure adopted by the cutting mechanism 200 references the relevant structure of a woven bag drawing device in the prior art (Chinese Utility Model Patent, Authorization Announcement No.: CN222135934U).

[0041] In embodiments of this utility model, such as Figures 1 to 5 As shown, the wire drawing mechanism 300 further includes: a connecting protrusion 307, a connecting seat 308, a ball bearing 309, and a first limiting cover 310; the two connecting protrusions 307 are respectively disposed on both sides of the adjusting groove, and the two connecting protrusions 307 are arranged opposite to each other; the two connecting seats 308 are respectively fixed on the two connecting protrusions 307, and the end of the connecting seat 308 away from the connecting protrusion 307 is provided with a semi-circular groove; the ball bearing 309 is respectively embedded in the groove of the connecting seat 308 and the annular sliding groove of the positioning ring 303; the first limiting cover 310 is installed on the connecting seat 308, the first limiting cover 310 is wrapped around the outside of the ball bearing 309, and at least part of the ball bearing 309 is embedded in the first limiting cover 310.

[0042] By setting two connecting protrusions 307 on both sides of the adjusting groove and arranging them opposite each other, and by welding two connecting seats 308 to the connecting protrusions 307, with a semi-circular groove at the end of the connecting seat 308 facing away from the connecting protrusions 307, the adjusting block 304 can support the connecting seat 308 through the connecting protrusions 307. By embedding the balls 309 into the groove of the connecting seat 308 and the annular groove of the positioning ring 303, when the positioning ring 303 rotates, the balls 309 move in the groove of the connecting seat 308 and the annular groove of the positioning ring 303. The positioning ring 303 rotates within the annular groove, thereby enabling the adjusting block 304 and the positioning ring 303 to move synchronously via the two connecting protrusions 307 and the two balls 309. By fixing the first limiting cover 310 to the connecting seat 308 with a nut, and by having the first limiting cover 310 wrapped around the outside of the balls 309, and by having at least some of the balls 309 embedded in the first limiting cover 310, more than half of the balls 309 are located in the grooves of the first limiting cover 310 and the connecting seat 308, thereby enabling the first limiting cover 310 to limit the balls 309.

[0043] With the above structure, by embedding the ball bearings 309 into the groove of the connecting seat 308, the first limiting cover 310, and the annular groove of the positioning ring 303, respectively, when the positioning ring 303 rotates, it drives the ball bearings 309 to rotate in the groove of the connecting seat 308 and the annular groove of the positioning ring 303. This allows the adjusting block 304 to move synchronously with the positioning ring 303 through the two connecting protrusions 307 and the two ball bearings 309. Thus, the distance between multiple positioning rings can be adjusted by moving multiple adjusting blocks 304.

[0044] In embodiments of this utility model, such as Figures 1 to 5 As shown, the wire drawing mechanism 300 further includes: a first gear 311 and a second gear 312; the first gear 311 is fitted onto one end of the first rotating roller 302 and is located on the side of the mounting plate 301 away from the positioning ring; the second gear 312 is fitted onto one end of the second rotating roller 306 and is located above the first gear 311, and the second gear 312 meshes with the first gear 311.

[0045] By mounting the first gear 311 on one end of the first rotating roller 302 and positioning the first gear 311 on the side of the mounting plate 301 away from the positioning ring, the first gear 311 and the first rotating roller 302 can rotate synchronously. By mounting the second gear 312 on one end of the second rotating roller 306 and positioning the second gear 312 above the first gear 311, the second gear 312 and the second rotating roller 306 can rotate synchronously. By meshing the second gear 312 with the first gear 311, the first gear 311 and the second gear 312 can rotate in opposite directions, thereby enabling the first rotating roller 302 and the second rotating roller 306 to rotate in opposite directions.

[0046] With the above structure, by mounting the first gear 311 on one end of the first rotating roller 302 and the second gear 312 on one end of the second rotating roller 306, and with the second gear 312 meshing with the first gear 311, the first gear 311 causes the first rotating roller 302 and the second rotating roller 306 to rotate in opposite directions through the second gear 312, thereby enabling the first rotating roller 302 and the second rotating roller 306 to press and stretch the plastic filament.

[0048] By mounting the support plate 313 on the mounting plate 301 and positioning the support plate 313 below the first gear 311, mounting the support base 314 on the support plate 313, and mounting the motor 315 on the support base 314, the mounting plate 301 supports the motor 315 through the support plate 313 and the support base 314. By providing a first output shaft to the motor 315 and connecting the first output shaft of the motor 315 to one end of the first rotating roller 302, the motor 315 drives the first output shaft to rotate the first rotating roller 302. Thus, the first motor 315 provides power to the first rotating roller 302 and the second rotating roller 306 to rotate in opposite directions through the first gear 311 and the second gear 312.

[0049] In embodiments of this utility model, such as Figures 1 to 5 As shown, the wire drawing mechanism 300 also includes: a second limiting cover 316; the two second limiting covers 316 are fitted at both ends of the first rotating roller 302, and the two second limiting covers 316 are respectively located on both sides of the positioning ring.

[0050] By fitting two second limiting covers 316 onto both ends of the first rotating roller 302 and positioning the two second limiting covers 316 on both sides of the positioning ring, the two second limiting covers 316 limit the positioning ring, thereby enabling the positioning ring to move between the two second limiting covers 316.

[0051] In embodiments of this utility model, such as Figures 1 to 5 As shown, the wire drawing mechanism 300 also includes: a rubber sleeve; the rubber sleeve is an elastic body, the rubber sleeve is fitted on the outside of the second rotating roller 306, and the rubber sleeve is simultaneously in contact with at least five positioning rings 303.

At the same time, it can also enhance the extrusion and stretching effect of the second rotating roller 306 and the first rotating roller 302 on the plastic filament, further improving the product user experience.

At least two second moving blocks 3054 are fixedly connected to at least two adjusting blocks 304 respectively, and the at least two second moving blocks 3054 are located on both sides of the first moving block 3053. Two third moving blocks 3055 are fixedly connected to the two adjusting blocks 304, and the two third moving blocks 3055 are located on both sides of the second moving blocks 3054 away from the direction of the first moving block 3053. The pitch-changing mechanism 3056 is connected to the first moving block 3053, the second moving block 3054 and the third moving block 3055.

[0054] By mounting two first fixing plates 3051 on the base plate 100 with a gap between them and positioning them below the first rotating roller 302, the base plate 100 supports the two first fixing plates 3051. Similarly, by mounting a second fixing plate 3052 on the base plate 100 and connecting its two ends to the two first fixing plates 3051, the base plate 100 supports the second fixing plate 3052. This provides support, thereby increasing the stability of the first fixed plate 3051 and the second fixed plate 3052. By fixing the first movable block 3053 to the second fixed plate 3052, positioning the first movable block 3053 in the middle of the second fixed plate 3052, and fixing the first movable block 3053 to an adjusting block 304, the second fixed plate 3052 can be supported by the first movable block 3053 on an adjusting block 304.
