Description

Technical Field

[0001] This utility model relates to the field of stretch film production technology, and in particular to a high-efficiency stretch film mixing machine. Background Technology

[0002] Stretch film, as an important packaging material, is widely used in logistics, warehousing, food preservation, and other fields. During the production of stretch film, the uniformity of the raw material ratio and the mixing effect directly affect the quality of the final product.

[0003] For example, Chinese utility model patent application number 202022811335.5 discloses a raw material proportioning device for stretch film production, belonging to the field of stretch film production technology. This raw material proportioning device includes a frame, a mixing component, and a dispensing component. In use, a first electric cylinder drives a pusher plate to move within the proportioning chamber, changing the volume of the chamber to ensure the required proportion is met. Raw materials fall from the hopper into the proportioning chamber. When the chamber is full, a first electric guide rail, in conjunction with a first sliding block, seals the connection between the hopper and the proportioning chamber. A second electric cylinder drives a second sliding block to open the discharge port. The first electric cylinder pushes the pusher plate towards the discharge port, allowing the raw materials to fall from the discharge port into the mixing tank. The mixing component is then activated to stir the raw materials. The first electric cylinder, in conjunction with the pusher plate, allows the proportioning amount in the proportioning chamber to be adjusted according to on-site requirements. The proportioned raw materials can then be directly added to the mixing tank for further mixing, improving production efficiency.

[0004] Existing batching and mixing equipment mostly adopts a single mixing structure, which has limited mixing effect. During the rotation of traditional mixing rods, dead zones are easily formed in the batching tank, resulting in uneven mixing of materials. Especially near the bottom and walls of the tank, materials tend to accumulate and stick to the walls, affecting the quality of batching. Secondly, traditional batching machines have a single discharge method, usually with only one discharge port. During continuous production, it is necessary to wait for workers to transport the full batching tank away, empty it, and then return to continue receiving materials, resulting in frequent shutdowns while waiting for materials, which seriously affects production efficiency and causes discontinuous production rhythm.

[0005] Therefore, a high-efficiency mixing machine for stretch film batching with good mixing effect and high discharge efficiency is needed to solve the above technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient mixing and dispensing machine for stretch film.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency mixing wrapping film batching machine, comprising a base plate, four support legs fixedly installed on the top of the base plate, a batching tank fixedly connected to one side of the four support legs opposite to each other, a support plate fixedly connected to the top of the batching tank, a drive shaft rotatably connected to the bottom of the support plate, a driven shaft rotatably connected to the inner bottom surface of the batching tank and located on the outer wall of the drive shaft, a back-stirring component being provided on the driven shaft, a gearbox fixedly connected to the bottom of the batching tank, a drive component capable of driving the drive shaft and the driven shaft to rotate being provided at the bottom of the gearbox, two discharge pipes fixedly connected to the outer wall of the batching tank, a control box fixedly installed on each of the two discharge pipes, and a control component being provided on the control box.

[0008] The base plate serves as the fundamental support platform for the entire equipment, bearing the weight of all upper components. The outriggers raise the mixing tank to a suitable working height, facilitating the placement of the collection box below for material receiving. One of the outriggers also integrates a ladder function. The mixing tank, as the main container for material mixing, holds the stretch film raw materials to be mixed. The support plate is fixedly installed on the top of the mixing tank, providing an upper support point for the drive shaft and bearing the radial and axial loads generated when the drive shaft rotates. The drive shaft drives the cross-shaped agitator to rotate forward, realizing the main mixing of the materials in the mixing tank. The driven shaft rotates in the opposite direction to the drive shaft, driving the anti-stirring component to work. Double-lip sealing rings (not shown) are respectively installed at the positions where the drive shaft and driven shaft pass through the bottom of the mixing tank. The outer ring is a V-shaped rubber sealing ring, and the inner ring is a polytetrafluoroethylene sealing ring. A grease cavity is set between the two sealing rings, which can effectively adapt to the rotational movement of the shaft and provide a reliable sealing effect to prevent material leakage.

[0009] As a further description of the above technical solution: The drive assembly includes a drive motor fixedly mounted at the bottom of the gearbox, the output end of which rotates through the interior of the gearbox and is fixedly connected to a bevel gear.

[0010] The drive shaft rotates through the inside of the gearbox and is fixedly connected to the bevel gear. The drive motor serves as the sole power source for the entire system, driving the dual-shaft stirring system.

[0011] As a further description of the above technical solution: The outer wall of the first bevel gear is meshed with two second bevel gears, and the interiors of the two second bevel gears are rotatably connected to a connecting shaft via bearings.

[0012] One end of the connecting shaft is fixedly connected to the gearbox. The connecting shaft connects the second bevel gear and the gearbox, transmitting the rotational power of the second bevel gear and ensuring the continuity of transmission.

[0013] As a further description of the above technical solution: The outer walls of the two bevel gears 2 are meshed with bevel gear 3.

[0014] The top of the bevel gear three is fixedly connected to the driven shaft. The bevel gear three meshes with two bevel gear twos, driving the driven shaft to rotate in the opposite direction, thus realizing the dual-axis reverse rotation.

[0015] As a further description of the above technical solution: A cross-shaped stirring frame is fixedly installed on the outer wall of the drive shaft, and several triangular frames are fixedly connected to the bottom of the cross-shaped stirring frame.

[0016] The forward rotation of the cross-shaped mixing rack generates strong mixing and shearing forces, achieving initial mixing of the materials.

[0017] As a further description of the above technical solution: The anti-stirring assembly includes two inclined rods fixedly mounted on the outer wall of the driven shaft by a circular block, and a reinforcing ring is fixedly connected to one end of the two inclined rods.

[0018] The inclined bar, in conjunction with the tripod, is specifically designed to scrape the material from the conical area at the bottom of the mixing tank, preventing accumulation in the bottom corner and ensuring that all materials participate in the mixing process.

[0019] As a further description of the above technical solution: An L-shaped scraper is fixedly connected to the top of the reinforcing ring.

[0020] One end of each of the two L-shaped scrapers is rotatably connected to the drive shaft via a bearing. The L-shaped scrapers process the upper area of ​​the mixing tank to prevent material from adhering to the inner wall.

[0021] As a further description of the above technical solution: The control assembly includes a control rod rotatably mounted on one side of the control box. One end of the control rod extends into the interior of the control box and is fixedly connected to a worm gear. A worm wheel is meshed with the outer wall of the worm gear.

[0022] The worm gear transmits the rotational motion of the control lever to the worm wheel, thus playing a role in transmission and speed reduction. The worm gear and worm wheel also have a self-locking function.

[0023] As a further description of the above technical solution: The worm gear is fixedly connected to a control shaft inside, and the outer wall of the control shaft extends into the discharge pipe and is fixedly connected to a baffle.

[0024] The baffle directly controls the opening and closing of the discharge port, and the flow rate is controlled by adjusting the angle.

[0025] As a further description of the above technical solution: Two collection boxes are movably placed on the top of the base plate, and a ladder is fixedly connected to one of the legs.

[0026] The collection box receives the mixed materials flowing out of the discharge pipe, and works with the double discharge pipes to achieve continuous production. The ladder makes it easy for workers to put raw materials into the mixing tank. It is fixed on the support legs, has a stable structure, and is easy to operate.

[0027] This utility model has the following beneficial effects: 1. Compared with existing technologies, this high-efficiency mixing stretch film batching machine adopts a dual-shaft counter-rotating mixing system through the coordinated use of drive components, drive shaft, driven shaft and anti-stirring components. The drive shaft drives the cross-shaped stirring frame for main mixing, and the driven shaft drives the anti-stirring component for auxiliary mixing. Compared with the traditional single mixing structure, the mixing efficiency and uniformity are greatly improved. Moreover, through the combined action of the tripod and the inclined rod, the material at the bottom of the batching tank is effectively stirred, eliminating the dead corner area that exists in traditional mixing equipment and preventing material accumulation and sticking to the wall.

[0028] 2. Compared with existing technologies, this high-efficiency mixing stretch film batching machine, through the coordinated use of structures such as discharge pipes, control boxes, control components, and collection boxes, and by using the control components equipped in each discharge pipe with a worm gear transmission mechanism, can precisely adjust the opening and closing angle of the baffles to achieve precise control of the discharge flow rate. Operators can flexibly adjust the discharge speed according to actual needs to adapt to different production requirements. At the same time, through two independent discharge pipes, they can work alternately to achieve continuous material receiving operations without stopping the machine, significantly improving overall production efficiency.

A bevel gear 14 is meshed on the outer wall of the two bevel gears 12. The top of the bevel gear 14 is fixedly connected to the driven shaft 6. The bevel gear 14 meshes with the two bevel gears 12, driving the driven shaft 6 to rotate in the opposite direction, thus achieving dual-shaft reverse rotation.

[0034] A cross-shaped stirring frame 15 is fixedly installed on the outer wall of the drive shaft 5. Several triangular frames 16 are fixedly connected to the bottom of the cross-shaped stirring frame 15. The cross-shaped stirring frame 15 rotates in the forward direction to generate strong stirring and shearing force, thereby achieving the initial mixing of materials.

[0035] The anti-stirring assembly includes two inclined rods 17 fixedly mounted on the outer wall of the driven shaft 6 via a circular block. One end of the two inclined rods 17 is fixedly connected to a reinforcing ring 26. The inclined rods 17, together with the tripod 16, are used to scrape the material in the conical area at the bottom of the mixing tank 3 to prevent accumulation in the bottom dead corner and ensure that all materials participate in the mixing. The top of the reinforcing ring 26 is fixedly connected to an L-shaped scraper 18. One end of the two L-shaped scrapers 18 is rotatably connected to the drive shaft 5 via a bearing.

[0036] The control assembly includes a control rod 19 rotatably mounted on one side of the control box 9. One end of the control rod 19 extends into the control box 9 and is fixedly connected to a worm gear 20. A worm wheel 21 is meshed with the outer wall of the worm gear 20. The worm gear 20 transmits the rotational motion of the control rod 19 to the worm wheel 21, which serves as a transmission and deceleration mechanism. The worm wheel 21 and worm gear 20 have a self-locking function. A control shaft 22 is fixedly connected inside the worm wheel 21. The outer wall of the control shaft 22 extends into the discharge pipe 8 and is fixedly connected to a baffle 23. The baffle 23 directly controls the opening and closing degree of the discharge port, and flow control is achieved by adjusting the angle.

[0037] Two collection boxes 24 are movably placed on the top of the base plate 1. A ladder 25 is fixedly connected to one of the support legs 2. The collection box 24 receives the mixed material flowing out from the discharge pipe 8. It works with the double discharge pipes 8 to achieve continuous production. The ladder 25 makes it easy for workers to put raw materials into the mixing tank 3. It is fixed on the support leg 2, making the structure stable and easy to operate.

[0038] Working principle: First, when using the equipment, the operator can pour the raw material of the stretch film into the mixing tank 3 through the ladder 25. After the material is prepared, the operator can start the controller on the support leg 2, which will start the drive motor 10. The output end of the motor will rotate, driving the bevel gear 11 to rotate, which will cause the drive shaft 5 to rotate. This will drive the cross stirring frame 15 and the triangular frame 16 to rotate in the forward direction, thus performing the main stirring. Then, the rotation of the bevel gear 11 will drive the two meshing bevel gears 12 to rotate. The rotation of the bevel gears 12 will drive the bevel gear 14 to rotate, so that the driven shaft 6 rotates in the opposite direction to the drive shaft 5. This will drive the reverse stirring component, which will drive the slant bar 17 to rotate in the opposite direction to stir the material on the lower slope of the mixing tank 3. At the same time, the rotation of the slant bar 17 will drive the reinforcing ring 26 and the L-shaped scraper 18 to rotate, which will treat the upper area of ​​the mixing tank 3, prevent the material from sticking to the inner wall and causing accumulation, thereby eliminating the stirring dead corners in the mixing tank 3 and ensuring that the material is mixed evenly. After the ingredients are mixed, the worker places the collection box 24 under the discharge pipe 8. Then, the control lever 19 is rotated to drive the worm gear 20 to rotate, which in turn drives the worm wheel 21 to rotate. The worm wheel 21 then drives the control shaft 22 to adjust the opening and closing angle of the baffle 23 and control the discharge flow. When one of the collection boxes 24 is full, the discharge pipe 8 can be closed, and the other discharge pipe 8 can be started so that the other collection box 24 can receive the material. By having the two discharge pipes 8 work alternately, continuous material receiving without stopping the machine can be achieved, avoiding the production cycle interruption caused by the traditional single discharge port.
