Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a mixing device for producing plastic bags. Background Technology

[0002] Plastic bags are bag-shaped packaging containers made primarily of plastic. Plastic bag production mixing devices are key equipment in the plastic processing industry used in the production process of plastic bags. They are mainly used to fully mix and stir the various raw materials used to produce plastic bags to ensure that the raw materials are evenly distributed, laying the foundation for the subsequent production of plastic bags with stable quality.

[0003] A search revealed Chinese Patent Publication No. CN204773099U, which discloses a mixing device for raw materials used in plastic bag production. The device includes a main body with an inlet and an outlet located at the middle right side and bottom, respectively. A feeding cylinder is installed in the middle of the main body, and a rotating shaft with threaded blades is installed inside the feeding cylinder. Multiple mixing devices are installed on the inner wall of the main body. A controller and an emergency control switch are located on the right side of the main body. This utility model's mixing device for raw materials used in plastic bag production utilizes an internal feeding cylinder and threaded blades on a rotating shaft to drive the mixing of the internal material. The raw materials tumble and mix within the mixing cylinder, allowing for the uniform mixing of large quantities of material in a short time. This spiral circulation mixing method results in more uniform, faster, and more efficient mixing. Combined with the internal mixing devices, it improves the mixing speed and quality of the raw materials. However, existing mixing devices cannot comprehensively mix the raw materials within the mixing cylinder from multiple directions, resulting in dead zones within the mixing cylinder, which hinders subsequent mixing operations. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mixing device for plastic bag production, which aims to improve the problem that existing mixing devices cannot fully mix the raw materials in the mixing tank from multiple directions, resulting in mixing dead zones in the mixing tank and making subsequent mixing work inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for producing plastic bags, comprising a mixing tank, a tank cover installed on the top of the mixing tank, a motor fixedly connected to the top of the tank cover, a fixed long rod fixedly connected to the output end of the motor, a gearbox fixedly connected to the upper middle part of the outer wall of the fixed long rod, fixed short rods rotatably connected to the left and right sides of the outer wall of the gearbox, a plurality of plow-shaped blades fixedly connected at equal intervals to the outer wall of the fixed long rod, an eccentric wheel fixedly connected to the bottom end of the fixed long rod, a plurality of spring scrapers fixedly connected at equal intervals to the bottom of the inner wall of the mixing tank, a plurality of guide grooves equally spaced on the inner wall of the mixing tank, and a plurality of adjusting mechanisms equally spaced inside the mixing tank for adjusting the angle.

[0006] The above technical solution works as follows: The motor drives a fixed long rod to rotate, transmitting power to the gearbox. The gearbox, through its internal gears, synchronously distributes power to the fixed short rods on both sides, causing them to rotate counterclockwise at 120 rpm. This rapidly creates a complex and high-intensity convective shear flow field within the mixing tank. The main stirring shaft, located at the center line of the mixing tank, generates centripetal force that drives the material towards the center. Meanwhile, the eccentrically arranged auxiliary stirring shafts break the symmetry of the material flow, allowing the material to fully tumble and mix in all areas of the tank, avoiding dead zones. Multiple plow-shaped blades, equidistantly fixed on the main stirring shaft, generate axial propulsion force during rotation, pushing the material along the axial direction of the mixing tank. On one hand, the plow-shaped blades can apply radial shearing force to the material, breaking up agglomerated material particles and promoting uniform mixing. The six sets of L-shaped blades on the auxiliary stirring shaft are staggered at 45° with the plow-shaped blades on the main stirring shaft. When the auxiliary stirring shaft rotates at high speed, the L-shaped blades can not only enhance the radial shearing effect and further refine the material, but also guide the material to areas not fully covered by the main stirring shaft using their special angle, achieving all-round efficient mixing. Under the guidance of the guide channel, the material will flow along the internal spiral path, further enhancing the mixing effect of the material. The spring scraper can periodically clean the wall under the rotation of the eccentric wheel at the bottom of the fixed long rod, preventing the material from settling at the bottom of the mixing tank.

[0007] As a further description of the above technical solution:

[0008] The adjusting mechanism includes hollow blocks, which are equidistantly installed inside the mixing tank. A push rod is fixedly connected to the rear side of the interior of the hollow block, and a rack is fixedly connected to the front end of the push rod. A support frame is fixedly connected inside the hollow block, and a fixed short column is rotatably connected inside the support frame. An arc-shaped gear is fixedly connected to the middle of the outer wall of the fixed short column, and the arc-shaped gear meshes with the rack. An L-shaped stirring paddle is fixedly connected to the bottom of the arc-shaped gear.

[0009] Through the above technical solution: when it is necessary to adjust the angle of the L-shaped stirring paddle, the push rod is activated to push the rack at the front end to move forward in the hollow block. Since the rack is meshed with the arc gear, the movement of the rack will drive the arc gear to rotate around the fixed short column. The fixed short column and the arc gear on the outer wall rotate in the support frame. As the arc gear rotates, the L-shaped stirring paddle fixedly connected to its bottom will also change its angle accordingly, thereby realizing the adjustment of the angle of the L-shaped stirring paddle to adapt to different mixing needs. After adjusting the angle, when the mixing tank is working, the L-shaped stirring paddle will rotate together with the fixed short rod. The L-shaped structure can push and shear the material in different directions, enhancing the mixing effect of the material.

[0010] As a further description of the above technical solution:

[0011] A screw is threadedly connected to the front side of the outer wall of the mixing tank, and a warning sign is threadedly connected to the outer wall of the screw.

[0012] The above technical solution allows the warning sign on the front of the mixing tank to remind workers of operating procedures when using the mixing tank, thereby reducing the probability of accidents.

[0013] As a further description of the above technical solution:

[0014] The bottom of the outer wall of the mixing tank is fixedly connected with multiple fixed base plates at equal intervals, and the top of the fixed base plates is threaded with two screws.

[0015] The above technical solution allows the fixed base plate at the bottom of the outer wall of the mixing tank to serve to fix the mixing tank in place.

[0016] As a further description of the above technical solution:

[0017] A hollow box is fixedly connected to the rear side of the outer wall of the mixing tank, and a drawer is slidably connected inside the hollow box.

[0018] The above technical solution allows for the convenient storage of tools used daily and for maintenance through sliding drawers inside the hollow box.

[0019] As a further description of the above technical solution:

[0020] A second handle is fixedly connected to the rear side of the outer wall of the drawer, and a protective sleeve is fixedly connected to the outer wall of the second handle.

[0021] Through the above technical solution, handle two can facilitate the opening and closing of the drawer box by staff for operation.

[0022] As a further description of the above technical solution:

[0023] The upper part of the outer wall of the mixing tank is equidistantly connected to multiple rotating handles, and the top of each rotating handle is threaded with a threaded rod.

[0024] The above technical solution involves rotating the threaded rod at the top of the handle, which strengthens the seal of the bucket lid.

[0025] As a further description of the above technical solution:

[0026] The top front and back sides of the bucket lid are fixedly connected to a handle, and the outer wall of the handle is fixedly connected to an anti-slip sleeve.

[0027] The above technical solution allows the handle on the top of the lid to facilitate workers in picking up, installing, and using the lid.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor drives the fixed long rod to rotate and transmits the power to the gearbox. The gearbox distributes the power synchronously to the fixed short rods on the left and right sides through the internal gears, causing them to rotate counterclockwise at 120 rpm. This quickly forms a complex and high-intensity convective shear flow field. The spring scraper can clean the material at the bottom of the mixing tank under the rotation of the eccentric wheel, preventing sedimentation. This avoids the problem that existing mixing devices cannot fully mix the raw materials in the mixing tank from multiple directions, resulting in dead zones in the mixing tank that are inconvenient for subsequent mixing.

[0030] 2. In this utility model, the rack is pushed forward by the push rod, and the rack meshes with the arc-shaped gear, driving the gear to rotate around the short column. The rotation of the gear drives the stirring paddle to change its angle to adapt to different stirring needs. When the mixing tank is working, the L-shaped stirring paddle rotates with the short rod. The L-shaped structure can effectively push and shear the material, improve the mixing effect, and thus improve the uniformity and efficiency of the stirring. Attached Figure Description

[0041] Specifically, the motor 6 drives the fixed long rod 19 to rotate, transmitting power to the gearbox 17. The gearbox 17 distributes power synchronously to the fixed short rods 21 on both sides through internal gears, causing them to rotate counterclockwise at 120 rpm. This rapidly creates a complex and high-intensity convective shear flow field within the mixing tank 1. The main stirring shaft is located at the center line of the mixing tank 1, and the centripetal force generated by its rotation drives the material to converge towards the center of the tank. The eccentrically arranged auxiliary stirring shaft breaks the symmetry of the material flow, allowing the material to fully tumble and mix in all areas of the tank, avoiding dead zones. Multiple plow-shaped blades 18 fixed at equal intervals on the main stirring shaft generate axial propulsion force on the material during rotation, pushing the material to flow axially along the mixing tank 1. On the other hand, the plow-shaped blades 18 apply radial shear force to the material, breaking up agglomerated material particles and promoting uniform mixing. The six sets of L-shaped blades on the auxiliary stirring shaft are staggered at 45° with the plow-shaped blades 18 on the main stirring shaft. When the stirring shaft rotates at high speed, the L-shaped blades not only enhance the radial shearing effect and further refine the material, but also guide the material flow to areas not fully covered by the main stirring shaft using their special angle, achieving all-round efficient mixing. Under the guidance of the guide channel 20, the material will flow along the internal spiral path, further enhancing the mixing effect of the material. The spring scraper 23 can periodically clean the wall under the rotation of the eccentric wheel 22 at the bottom of the fixed long rod 19, preventing the material from settling at the bottom of the mixing tank 1.

The drawer 14 can facilitate the staff to open and close the drawer 16 for use.

[0043] Specifically, when the angle of the L-shaped impeller 202 needs to be adjusted, the push rod 203 is activated to push the rack 204 at the front end to move forward within the hollow block 201. Since the rack 204 is meshed with the arc gear 207, the movement of the rack 204 will drive the arc gear 207 to rotate around the fixed short column 206. The fixed short column 206 and the arc gear 207 on the outer wall rotate within the support frame 205. As the arc gear 207 rotates, the L-shaped impeller 202 fixedly connected to its bottom will also change its angle accordingly, thereby realizing the adjustment of the angle of the L-shaped impeller 202 to adapt to different stirring needs. Subsequently, when the mixing tank 1 is in operation, the L-shaped stirring paddle 202 will rotate together with the fixed short rod 21. The L-shaped structure can push and shear the material in different directions, enhancing the mixing effect of the material.

[0046] Working Principle: The motor 6 drives the fixed long rod 19 to rotate, transmitting power to the gearbox 17. The gearbox 17, through its internal gears, synchronously distributes power to the fixed short rods 21 on both sides, causing them to rotate counterclockwise at 120 rpm. This rapidly creates a complex and high-intensity convective shear flow field within the mixing tank 1. The main stirring shaft, located at the center line of the mixing tank 1, generates centripetal force that drives the material towards the center. The eccentrically arranged auxiliary stirring shafts break the symmetry of the material flow, allowing the material to fully tumble and mix in all areas of the tank, avoiding dead zones. Multiple plow-shaped blades 18, equidistantly fixed on the main stirring shaft, exert axial propulsion on the material during rotation, pushing it along the axial direction of the mixing tank 1. Simultaneously, the plow-shaped blades 18 apply radial shear force to the material, breaking up agglomerated particles. To disperse and promote uniform mixing, the six sets of L-shaped blades on the auxiliary stirring shaft are staggered at 45° with the plow-shaped blades 18 on the main stirring shaft. When the auxiliary stirring shaft rotates at high speed, the L-shaped blades not only enhance the radial shearing effect and further refine the material, but also guide the material to areas not fully covered by the main stirring shaft using their special angle, achieving all-round efficient mixing. Under the guidance of the guide channel 20, the material will flow along the internal spiral path, further enhancing the mixing effect. The spring scraper 23 can periodically clean the wall under the rotation of the eccentric wheel 22 at the bottom of the fixed long rod 19, preventing the material from settling at the bottom of the mixing tank 1. This avoids the problem that existing stirring devices cannot fully mix the raw materials in the mixing tank 1 in multiple directions, resulting in mixing dead corners in the mixing tank 1, which is not convenient for subsequent mixing work.

[0047] When the angle of the L-shaped stirring paddle 202 needs to be adjusted, the push rod 203 is activated to push the rack 204 at the front end to move forward inside the hollow block 201. Since the rack 204 is meshed with the arc gear 207, the movement of the rack 204 will drive the arc gear 207 to rotate around the fixed short column 206. The fixed short column 206 and the arc gear 207 on the outer wall rotate inside the support frame 205. As the arc gear 207 rotates, the L-shaped stirring paddle 202 fixedly connected to its bottom will also change its angle accordingly, thereby realizing the adjustment of the angle of the L-shaped stirring paddle 202 to adapt to different stirring needs. After the angle is adjusted, when the mixing tank 1 is working, the L-shaped stirring paddle 202 will rotate together with the fixed short rod 21. The L-shaped structure can push and shear the material in different directions, enhance the mixing effect of the material, and thus improve the uniformity and efficiency of the stirring.
