Description

Technical Field

[0001] The utility model relates to the field of woven bag processing, in particular to an extrusion device for woven bag processing. Background Art

[0002] Plastic woven bags are mainly made of polypropylene resin, extruded and stretched into flat filaments, and then woven and bagged. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. During the production process of plastic woven bags, an extrusion device is required to extrude the raw materials.

[0003] For example, the patent document with the publication number CN220031109U discloses an extrusion device for plastic woven bag production. By setting a telescopic cylinder, a hinge rod, an L-shaped connecting block and a valve plate, the control of the feeding amount is realized. The operation of the telescopic cylinder will push the hinge rod to move vertically, and through the hinge connection with the L-shaped connecting block, the L-shaped connecting block is controlled to drive the valve plate to flip, changing the opening size inside the feeding box and controlling the feeding amount of plastic particles. However, no matter the size of the opening, there is a possibility of blockage. Therefore, changing the opening size only controls the feeding amount, but it is difficult to effectively avoid the problem of blockage at the feeding port. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an extrusion device for woven bag processing to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] An extrusion device for woven bag processing includes an extrusion barrel. An extrusion mechanism is arranged inside the extrusion barrel. A feeding hopper is fixed at the top of one end of the extrusion barrel. A feeding mechanism is arranged inside the feeding hopper. The feeding mechanism includes a rotating shaft. An activity shaft is movably installed inside the bottom end of the rotating shaft along its axial direction. A feeding blade is fixedly connected to the activity shaft. The top of the feeding hopper is fixedly connected with a top plate. The rotating shaft is rotatably connected to the top plate. An auxiliary mechanism for moving the activity shaft up and down is arranged on the activity shaft. A transmission mechanism for driving the rotating shaft to rotate is arranged on the top of the top plate.

[0007] Preferably, the top end of the activity shaft extends into the rotating shaft. A spring is fixedly connected to the top end of the activity shaft. The top end of the spring is fixedly connected to the inner top wall of the rotating shaft. A sliding block is fixedly connected to the activity shaft. A sliding groove is formed on the inner wall of the rotating shaft. The sliding block is slidably matched with the sliding groove in the vertical direction.

[0008] Preferably, the auxiliary mechanism includes a limiting ring which is attached to the inner wall of the feed hopper. A plurality of connecting rods are fixedly connected to the inner wall of the limiting ring, and the other ends of the connecting rods are fixedly connected to the movable shaft. A pressing rod is fixedly connected to the bottom of the limiting ring, and a convex block for jacking up the pressing rod is fixedly connected to the inner wall of the feed hopper. The convex block is located above the blanking blade and below the limiting ring.

[0009] Preferably, the convex block is semi-circular with lower ends and a higher middle part, and the bottom of the pressing rod is semi-spherical.

[0010] Preferably, the extrusion mechanism includes a motor which is fixedly connected to one end of the extrusion barrel. The output shaft of the motor is fixedly connected with an extrusion shaft which is rotatably installed inside the extrusion barrel, and an extrusion blade is fixedly connected to the extrusion shaft.

The blanking blade can evenly send the raw materials into the extrusion barrel, avoiding the blockage of the feed hopper. At the same time, the auxiliary mechanism can make the blanking blade move up and down intermittently, improving the disturbance effect on the raw materials and further avoiding the occurrence of blockage. In addition, since the power of the blanking mechanism comes from the extrusion mechanism, when the extrusion speed of the extrusion mechanism increases, the corresponding blanking speed also increases, and vice versa. In this way, the feeding and extrusion speeds can be adapted to ensure the extrusion effect of the materials.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1 - 6As shown in the figure, an extrusion device for woven bag processing includes an extrusion barrel 1. An extrusion mechanism is arranged inside the extrusion barrel 1. At the top of one end of the extrusion barrel 1, a feed hopper 101 is connected by screws. A feeding mechanism is arranged inside the feed hopper 101. The feeding mechanism includes a rotating shaft 301. An activity shaft 302 is movably installed along the axial direction inside the bottom end of the rotating shaft 301. A feeding blade 303 is welded on the activity shaft 302. The top of the feed hopper 101 is connected by screws to a top plate 102. The rotating shaft 301 is connected to the top plate 102 through a bearing. An auxiliary mechanism for moving the activity shaft 302 up and down is arranged on the activity shaft 302. A transmission mechanism for driving the rotation of the rotating shaft 301 is arranged on the top of the top plate 102.

[0026] The top end of the activity shaft 302 extends into the inside of the rotating shaft 301. A spring 304 is fixedly connected to the top end of the activity shaft 302. The top end of the spring 304 is fixedly connected to the inner top wall of the rotating shaft 301. A slider 305 is fixedly connected to the activity shaft 302. A chute 306 is formed on the inner wall of the rotating shaft 301. The slider 305 is slidably matched with the chute 306 in the vertical direction. Through the cooperation of the slider 305 and the chute 306, the activity shaft 302 can move up and down along the axial direction of the rotating shaft 301, and it is ensured that the rotating shaft 301 can drive the activity shaft 302 to rotate. When the activity shaft 302 rotates, it drives the feeding blade 303 to rotate. The feeding blade 303 evenly conveys the raw materials downward into the inside of the extrusion barrel 1, which can prevent the feed hopper 101 from being blocked.

[0027] The auxiliary mechanism includes a limiting ring 401. The limiting ring 401 is attached to the inner wall of the feed hopper 101. A plurality of connecting rods 402 are fixedly connected to the inner wall of the limiting ring 401. The other ends of the connecting rods 402 are fixedly connected to the activity shaft 302. The limiting ring 401 plays a role in limiting the rotating shaft 301, preventing the rotating shaft 301 from being skewed and ensuring the stability of the rotation of the rotating shaft 301. A pressing rod 403 is fixedly connected to the bottom of the limiting ring 401. A convex block 103 for jacking up the pressing rod 403 is fixedly connected to the inner wall of the feed hopper 101. The convex block 103 is located above the feeding blade 303 and below the limiting ring 401. The convex block 103 is semi-circular with low ends and high middle. The bottom of the pressing rod 403 is semi-spherical. The spring 304 always exerts a downward pressure on the rotating shaft 301, so that the limiting ring 401 presses on the convex block 103, and the limiting ring 401 rotates together with the rotating shaft 301. Therefore, when the pressing rod 403 contacts the convex block 103, the pressing rod 403 drives the limiting ring 401 to move up. The limiting ring 401 drives the activity shaft 302 to move up, so that the feeding blade 303 moves up. When the pressing rod 403 separates from the convex block 103, the feeding blade 303 moves down again, so that the feeding blade 303 intermittently moves up and down, disturbing the raw materials in the feed hopper 101 and further preventing the feed hopper 101 from being blocked.

[0028] The extrusion mechanism includes a motor 201, which is fixedly connected to one end of the extrusion barrel 1. The output shaft of the motor 201 is fixedly connected with a material extrusion shaft 202. The material extrusion shaft 202 is rotatably installed inside the extrusion barrel 1, and a material extrusion blade 203 is fixedly connected to the material extrusion shaft 202.

[0029] The transmission mechanism includes a transmission box 501, which is fixedly connected to the top of the top plate 102. A transmission shaft 502 is connected in the transmission box 501 through a bearing. A driving bevel gear 503 is fixedly connected to the transmission shaft 502. The driving bevel gear 503 meshes with a driven bevel gear 504. The driven bevel gear 504 is fixedly connected to the top end of the rotating shaft 301. One end of the transmission shaft 502 is provided with a belt assembly 505. The input end of the belt assembly 505 is connected to the material extrusion shaft 202. By driving the material extrusion shaft 202 to rotate through the motor 201, the material extrusion blade 203 extrudes the raw material in the extrusion barrel 1. And the material extrusion shaft 202 drives the transmission shaft 502 to rotate through the belt assembly 505. Through the cooperation of the driving bevel gear 503 and the driven bevel gear 504, the transmission shaft 502 drives the rotating shaft 301 to rotate, so as to realize feeding and extrusion at the same time, and the feeding speed is adapted to the extrusion speed to ensure the extrusion effect.

[0030] Working principle: When in use, pour the raw materials into the feeding hopper 101. Drive the extrusion shaft 202 to rotate through the motor 201. The extrusion shaft 202 drives the transmission shaft 502 to rotate through the belt assembly 505. Through the cooperation of the driving bevel gear 503 and the driven bevel gear 504, the transmission shaft 502 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the movable shaft 302 to rotate through the cooperation of the slider 305 and the chute 306. The movable shaft 302 drives the blanking blade 303 to rotate. The blanking blade 303 evenly conveys the raw materials downward into the extrusion barrel 1, which can prevent the feeding hopper 101 from being blocked. After the raw materials enter the extrusion barrel 1, they are heated into molten materials. The extrusion shaft 202 drives the extrusion blade 203 to rotate to extrude the molten materials. When the movable shaft 302 rotates, it drives the limiting ring 401 to rotate through the connecting rod 402. The limiting ring 401 drives the extrusion rod 403 to rotate. When the extrusion rod 403 contacts the convex block 103, the extrusion rod 403 drives the limiting ring 401 to move upward. The limiting ring 401 drives the movable shaft 302 to move upward, and the spring 304 is compressed, so that the blanking blade 303 moves upward. When the extrusion rod 403 disengages from the convex block 103, the spring 304 rebounds, and the blanking blade 303 moves downward to reset, so that the blanking blade 303 intermittently moves up and down to disturb the raw materials in the feeding hopper 101, further preventing the feeding hopper 101 from being blocked. When it is necessary to adjust the extrusion speed, just change the rotation speed of the motor 201. For example, when the rotation speed of the motor 201 increases, the rotation speed of the extrusion shaft 202 also increases, thereby increasing the extrusion speed. At the same time, the transmission mechanism also increases the rotation speed of the rotating shaft 301, thereby increasing the feeding speed, making the extrusion speed match the feeding speed, and avoiding the problems of fast extrusion speed and slow feeding speed or slow extrusion speed and fast feeding speed, so as to ensure the extrusion effect.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
