Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-6 PVC film production mixing equipment, including feeding equipment 1 and mixing equipment 2;

[0025] The feeding device 1 is fixedly installed on the top of the mixing support 3, and the mixing device 2 is fixedly installed below the mixing support 3;

[0026] The feeding device 1 includes a feeding hopper 101; the feeding hopper 101 is fixedly installed on the top of the mixing support 3 via a hopper bracket 102. In this design, the side of the mixing support 3 should also be equipped with components such as stairs, or the mixing support 3 should be level with the second floor of the factory where it is installed, so as to facilitate the operation of personnel going up and down. The materials to be fed can be temporarily piled on the top of the mixing support 3.

[0027] The hopper 101 is an inverted conical shell. The lower end of the hopper 101 is provided with a discharge port 103, and an electric valve 104 is installed at the discharge port 103. The outlet of the electric valve is connected to the mixing device 2 through a hose 105.

[0028] The top of the hopper 101 is provided with a feeding port 106, and a guide cover 107 is installed on the top of the feeding port 106. The guide cover 107 is used to guide the material to enter the feeding port 106.

[0029] Meanwhile, in this solution, a grid 108 is also installed on the feeding port 106; when using this utility model, the worker places the whole package of raw materials on the grid 108, then punctures or unseals the raw material package, and then puts the raw materials into the feeding hopper 101; the grid 108 can first prevent the package from entering the feeding hopper 101, and also play the role of placing the raw material package, which is convenient for the worker to operate.

[0030] The material enters the feeding hopper 101 and enters the mixing equipment 2 by gravity.

[0031] The mixing device 2 includes a mixing cylinder 4 and a mixing apparatus; the mixing apparatus includes a cover 201 and a stirring shaft 204. A mixing motor 203 is fixedly installed at the top center of the cover 201 via a motor bracket 202. A spiral stirring blade 205 is provided on the stirring shaft 204. The top of the stirring shaft 204 passes through the cover 201 and is connected to the output shaft of the mixing motor 203. At the same time, the stirring shaft 204 is also rotatably and sealingly connected to the cover 201.

[0032] The top of the cover 201 is also connected to a feed pipe 206, and the top of the feed pipe 206 is fixedly connected to the lower end of the hose 105.

[0033] In this solution, the mixing device 2 also includes a mixing device lifting structure 210, which includes a linear module 211. The linear module 211 is vertically fixedly installed on the top of the fixed bracket 212. The slide of the linear module 211 is also fixedly connected to one end of the connecting bracket 213, and the other end of the connecting bracket 213 is fixedly installed on one side of the motor bracket 202.

[0034] This utility model can drive the mixing device to move up and down through the linear module 211, and the setting of the hose can keep the hopper 101 connected to the feed pipe 206. It is worth noting that the hopper will only start discharging when the mixing device is in the lowest position, that is, when the cover 201 is fastened to the top of the mixing cylinder 4.

[0035] The mixing cylinder 4 is a cylindrical shell with an opening at the top, and the mixing cylinder 4 is movably mounted on the movable trolley 401;

[0036] In use, the worker puts the raw materials into the feeding hopper 101, at which time the electric valve 104 is closed. The worker pushes the mixing cylinder 4 to the bottom of the mixing device using a movable trolley. Then, the linear module 211 drives the mixing device to descend, at which point the stirring shaft 204 is inserted into the mixing cylinder 4, and the cover 201 is fastened to the mixing cylinder 4. The electric valve 104 is opened, and the raw materials in the feeding hopper 101 enter the mixing cylinder 4 along the hose. Other raw materials can be added, and then the mixing motor 203 mixes and stirs the raw materials. After mixing is completed, the linear module 211 drives the mixing device to rise. After the stirring is completely removed from the mixing cylinder 4, the worker can remove the mixing cylinder 4 using the movable trolley 401.

[0037] In this solution, the trolley 401 includes a base 402, which is U-shaped. Wheels 403 are installed on the left and right sides of the front end of the base 402, and casters 404 are installed at the rear end of the base 402.

[0038] Two main columns 405 are vertically fixedly installed on the top of the vehicle base 402; the top of the two main columns 405 is rotatably connected to the middle rear position of the first connecting arm 406 via a pivot; a gripping rod 409 is fixedly connected between the front ends of the two first connecting arms 406; the rear end of the first connecting arm 406 is rotatably connected to the upper end of the second connecting arm 407 via a pivot, and the lower end of the second connecting arm 407 is fixedly connected to a barrel hoop 408, which is fixedly installed on the side wall of the mixing cylinder 4 by welding or riveting.

[0039] When the mixing cylinder 4 is performing mixing operations, the mixing cylinder 4 relies on gravity and is in contact with the ground. When it is necessary to move the mixing cylinder 4, the gripping rod 409 is pressed down. Since the pointer of the first connecting arm 406 is in the middle and slightly rear position, the worker only needs a small amount of force to keep the end of the mixing cylinder 4 suspended, thus making it convenient to move the mixing cylinder 4.
