Description

Technical Field

[0001] This utility model relates to the field of mulch film production technology, specifically a mixing device for mulch film production. Background Technology

[0002] Mulch film production refers to the manufacture of films used for agricultural mulching through specific processes. The main raw material is polyethylene resin, and various colors such as transparent, black, and green can be produced by adding different additives. Mulch film production requires a mixing device to mix the raw materials. A utility model patent with authorization announcement number CN219445711U discloses a mixing device for environmentally friendly mulch film production, including a cylinder. A motor is fixedly connected to the upper surface of the cylinder, and a first sealed bearing is fixedly embedded in the upper surface of the cylinder. A connecting box is fixedly connected to the inner wall of the cylinder, and a second sealed bearing is fixedly embedded in the bottom surface of the connecting box. A rotating rod is fixedly connected to the inner rings of the first and second sealed bearings.

[0003] The above technical solution solves the problem of the difficulty in quickly disrupting the layers formed from different raw materials, which leads to a significant time requirement for material mixing. However, this solution only mixes the raw materials; when producing mulch films of different colors, the existing materials in the mixing device need to be cleaned, and residual impurities cannot be quickly removed, resulting in reduced mulch film production efficiency. Therefore, it is necessary to develop a mixing device that can effectively mix the raw materials for mulch film production while facilitating the removal of internal impurities. Utility Model Content

[0004] To address the above technical problems, this utility model provides a mixing device that can fully mix the raw materials for mulch film production while facilitating the removal of internal impurities, thus solving the problem that existing mixing devices cannot easily remove internal impurities.

[0005] To solve the above-mentioned technical problems, the present invention provides a mixing device for mulch film production, comprising a base plate, a mixing tank fixedly connected to the base plate, a feed pipe fixedly connected to the top of the mixing tank, a stepper motor fixedly connected to the top of the mixing tank, a rotating frame rotatably connected to the mixing tank via a rotating shaft, the top of the rotating shaft being fixedly connected to the output end of the stepper motor, several identical cleaning scrapers and several identical rotating mixing plates fixedly connected to the inner wall of the rotating frame, a water storage tank fixedly connected to the base plate, a water pump fixedly connected to the water storage tank, an annular water storage pipe fixedly connected to the output end of the water pump, several identical water mist nozzles fixedly connected to the outer surface of the annular water storage pipe, the outer surface of the annular water storage pipe being fixedly connected to the inner wall of the mixing tank, and a discharge valve fixedly connected to the bottom of the mixing tank.

[0006] Furthermore, a bearing is fixedly connected to the mixing tank, and the upper part of the rotating shaft is rotatably connected to the mixing tank through the bearing.

[0007] Furthermore, four support bases are fixedly connected to the bottom surface of the base plate, and a fixing ring is fixedly connected to the outer surface of each support base. The top end of each fixing ring is fixedly connected to the bottom surface of the base plate.

[0008] Furthermore, a control panel is fixedly connected to the upper surface of the base plate, and a reinforcing frame is fixedly connected to the outside of the control panel.

[0009] Furthermore, a support frame is fixedly connected to the upper surface of the water storage tank, and the outer surface of the water pump is fixedly connected to the support frame.

[0010] Furthermore, a protective box is fixedly connected to the outer surface of the stepper motor, and the bottom surface of the protective box is fixedly connected to the top surface of the mixing tank.

[0011] Furthermore, a limiting ring is fixedly connected to the outer surface of the mixing tank, and several identical support rods are fixedly connected to the bottom end of the limiting ring. The bottom surface of each support rod is fixedly connected to the upper surface of the base plate, and two reinforcing rings are fixedly connected to the outer surface of each support rod. The top end of each reinforcing ring is fixedly connected to the bottom end of the limiting ring.

[0012] This utility model has the following advantages compared with the prior art:

[0013] 1. This utility model can stably output power through a stepper motor, and drive the rotating frame to rotate at high speed along the bearing through the rotating shaft. The rotating mixing plate can agitate the polyethylene resin and additives in the mixing tank in all directions, effectively breaking the raw material molding layer and avoiding the problem of "uneven local mixing" in traditional mixing. It greatly improves the mixing efficiency and uniformity of raw materials, and provides a guarantee for the stability of raw materials for mulch film production. On the other hand, a cleaning scraper is set on the inner wall of the rotating frame at the same time. The scraper can closely fit the inner wall of the mixing tank and scrape off the residual materials attached to the tank wall in real time during the rotation.

[0014] 2. This utility model features a cleaning system consisting of a water tank, a water pump, a ring-shaped water storage pipe, and water mist nozzles. This system can be started quickly. The water pump delivers clean water from the water tank to the ring-shaped water storage pipe, and then a water mist is formed through several evenly distributed water mist nozzles to cover the entire area, rinsing the residual material in the tank. Combined with a cleaning scraper, it achieves dual cleaning of "scraping + rinsing". This design can complete the cleaning of the tank without disassembling the equipment. It is especially suitable for changing production of different colored mulch films, solving the problem of reduced production efficiency caused by the long time required to clean residues in traditional devices, significantly shortening the production changeover interval, and improving the continuity of mulch film production.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-5 The mixing device for producing mulch film shown includes a base plate 1. A water storage tank 7 and a control panel 8 are fixedly connected to the upper surface of the base plate 1. A water pump 6 is fixedly connected to the upper surface of the water storage tank 7. An annular water storage pipe 5 is fixedly connected to the output end of the water pump 6. Several identical water mist nozzles 10 are fixedly connected to the outer surface of the annular water storage pipe 5. A mixing tank 2 is fixedly connected to the inner wall of the base plate 1. The outer surface of the annular water storage pipe 5 is fixedly connected to the inner wall of the mixing tank 2. A feed pipe 3 is fixedly connected to the top of the mixing tank 2. The interior of the mixing tank 2 is connected to a bearing 1. 3. A rotating shaft is rotatably connected, and a rotating frame 14 is fixedly connected to the rotating shaft through a connecting plate. The rotating frame 14 has an upper and lower ring frame structure. Several identical cleaning scrapers 15 are fixedly connected between the outer edges of the two ring frames. The cleaning scrapers 15 are made of elastic materials such as rubber. Several rotating mixing plates 16 are fixedly connected to the rotating shaft. A stepper motor 12 is fixedly connected to the top of the mixing tank 2 by bolts. The output end of the stepper motor 12 is fixedly connected to the top of the rotating shaft. A discharge port is fixedly connected to the bottom of the mixing tank 2. A discharge valve 22 is fixedly connected to the discharge port.

[0023] A control panel 8 is fixedly connected to the upper surface of the base plate 1. The control panel 8 is used to control the operation of the stepper motor 12 and the water pump 6. A reinforcing frame 9 is fixedly connected to the outer surface of the control panel 8. The bottom surface of the reinforcing frame 9 is fixedly connected to the upper surface of the base plate 1. The reinforcing frame 9 can reinforce the control panel 8 and prevent it from shifting its position during use.

[0024] A support frame 11 is fixedly connected to the outer surface of the water pump 6. The bottom surface of the support frame 11 is fixedly connected to the upper surface of the water storage tank 7. The support frame 11 can fix and support the water pump 6 to prevent it from swaying during use. A protective box 4 is fixedly connected to the outer surface of the stepper motor 12. The bottom surface of the protective box 4 is fixedly connected to the top of the mixing tank 2. The protective box 4 can protect the stepper motor 12 to prevent it from being interfered with by dust and impurities during use.

[0025] Four support bases 18 are fixedly connected to the bottom surface of the base plate 1. Each support base 18 has a fixed ring 19 fixedly connected to its outer surface. The top of each fixed ring 19 is fixedly connected to the bottom surface of the base plate 1. Through the support bases 18 and the fixed rings 19, the device as a whole can be stably supported, thereby enhancing the stability of the device.

[0026] A limiting ring 17 is fixedly connected to the outer surface of the mixing tank 2. Several identical support rods 20 are fixedly connected to the bottom end of the limiting ring 17. The bottom surface of each set of support rods 20 is fixedly connected to the upper surface of the base plate 1. The position of the mixing tank 2 can be fixed by the limiting ring 17 and the support rods 20 to prevent it from shaking violently during use. Two reinforcing rings 21 are fixedly connected to the outer surface of each set of support rods 20. The top end of each set of reinforcing rings 21 is fixedly connected to the bottom end of the limiting ring 17. The reinforcing rings 21 can reinforce the support rods 20 and the limiting ring 17 to prevent them from shaking or shifting in position during use.

[0027] A fixing frame 23 is fixedly connected to the outer surface of the discharge valve 22. The upper surface of the fixing frame 23 is fixedly connected to the bottom end of the mixing tank 2. The fixing frame 23 can fix the discharge valve 22 to prevent it from shaking during use.

[0028] The working principle of this embodiment is as follows:

[0029] During use, raw materials are slowly fed into the mixing tank 2 through the feed pipe 3 at the top. To prevent material accumulation at the feed inlet, a flexible rod can be used to assist in guiding the material, ensuring all raw materials enter the mixing tank 2. The speed and stirring time of the stepper motor 12 are set via the control panel 8. Starting the stepper motor 12 causes its output to drive the rotating shaft and rotating frame 14 to rotate along the bearing 13 on the inner wall of the mixing tank 2. Several cleaning scrapers 15 and rotating mixing plates 16 on the rotating frame 14 rotate synchronously with the rotating frame 14, performing "radial + axial" all-around agitation of the raw materials inside the tank. Radial agitation breaks up the lateral stratification of the raw materials, while axial agitation prevents material deposition at the bottom, effectively solving the problem of "uneven local mixing" in traditional devices. When switching to produce other color mulch films and needing to clean the residual raw materials in the mixing tank 2, this device achieves rapid cleaning through "water mist rinsing + scraper removal." The water pump 6 is started via the control panel 8. The water pump 6 pressurizes the clean water in the water storage tank 7 and delivers it to the annular water storage pipe 5, which is fixed to the inner wall of the mixing tank 2. The annular water storage pipe 5 adopts a wraparound design, with several water mist nozzles 10 evenly distributed around its outer surface. These nozzles spray fine water mist synchronously, forming a "full coverage" rinsing range. This provides initial rinsing of the inner wall of the mixing tank 2, the rotating frame 14, the rotating mixing plate 16, and the cleaning scraper 15. While the water mist is rinsing, the rotating frame 14 drives the cleaning scraper 15 to rotate slowly. The cleaning scraper 15 can closely adhere to the inner wall of the mixing tank 2, scraping away the residual raw materials attached to the tank wall as it rotates. The blocky residue scraped off by the scraper is dispersed by the water mist, forming wastewater. The discharge valve 22 is kept open, and the wastewater and residual impurities generated during rinsing are discharged through the discharge valve 22, completing the production change cleaning. The raw materials for the next color of mulch film can then be immediately put into the mixing process.
