[0001] This utility model relates to the field of PVC sheet processing technology, specifically to a closed-type dust-proof PVC sheet batching and mixing device. Background Technology

[0002] PVC sheet processing refers to the process of processing polyvinyl chloride (PVC) raw materials into sheets of various thicknesses, sizes and types, and then carrying out subsequent processing. PVC sheets are widely used in many fields such as construction, advertising, packaging, medical, and home furnishing. Its processing technology includes extrusion, molding, thermoforming, laser cutting, etc.

[0003] A mixing device is required during the processing of PVC sheets to mix PVC raw materials with other additives evenly. The mixing device is an indispensable piece of equipment in the production of PVC sheet plastic products, which can ensure the uniformity of the ingredients and the consistency of quality.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When using existing ordinary batching and mixing devices, raw material dust will escape from the outlet of the device and drift into the air during the feeding or mixing process, which will cause air pollution; 2. When using existing ordinary batching and mixing devices, the stirring blades are usually driven by a motor to rotate and stir the raw materials in the device. The stirring and mixing method is relatively simple and cannot fully agitate the raw materials in the device, resulting in poor stirring and mixing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a closed-type dust-proof PVC sheet batching and mixing device to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a closed-type dust-proof PVC sheet batching and mixing device, including a mixing tank assembly, a mixing component installed on the top of the mixing tank assembly, and a dust suction component and a feeding component installed on the top of the mixing component.

[0006] The stirring assembly includes a fixed plate, a protective shell is installed on the top of the fixed plate, a geared motor is installed on the top of the protective shell, and a first rotating rod and a second rotating rod are rotatably installed through the bottom of the fixed plate. A large gear and a spiral blade are installed sequentially from top to bottom on the outer wall of the first rotating rod, and a small gear and a stirring blade are installed sequentially from top to bottom on the outer wall of the second rotating rod.

[0007] The dust collection assembly includes an L-shaped plate and a centrifugal fan. A dust collection bag is installed at the air outlet of the centrifugal fan. A dust collection hood is installed on one side of the L-shaped plate, and a connecting pipe is installed on the top of the dust collection hood.

[0008] More preferably, the mixing tank assembly includes a tank body, and an electric valve and support legs are installed at the bottom of the tank body. There are four support legs in total, and the four support legs are arranged in a ring with the vertical center line of the tank body as the origin.

[0009] More preferably, the fixing plate is installed on the top of the tank, the first rotating rod is installed at the output end of the geared motor, and the spiral blades form a rotating mechanism with the geared motor through the first rotating rod.

[0010] More preferably, the large gear and the small gear are meshed and installed, and the outer wall of the second rotating rod is provided with a number of uniformly and equidistantly distributed stirring blades. The stirring blades are arranged in a ring with the vertical center line of the second rotating rod as the origin. The second rotating rod, the small gear and the stirring blades are set as a group, and there are a total of three groups. The three groups of the second rotating rod, the small gear and the stirring blades are arranged in a ring with the vertical center line of the first rotating rod as the origin.

[0011] More preferably, both the L-shaped plate and the centrifugal fan are installed on the top of the protective shell, and one end of the connecting pipe is connected to the air inlet of the centrifugal fan.

[0012] More preferably, the feeding assembly includes a feeding hopper mounted on the top of the fixed plate, a first rotary mounting seat mounted on one side of the inner wall of the L-shaped plate, a cover plate mounted on the top of the feeding hopper via a hinge, an electric push rod mounted on one side of the first rotary mounting seat, a second rotary mounting seat mounted on one side of the electric push rod, the second rotary mounting seat mounted on the top of the cover plate, and the external dimensions and structure of the first rotary mounting seat and the second rotary mounting seat being identical.

[0013] More preferably, the bottom of the cover plate is provided with a sealing ring, and the cover plate forms a sealing structure with the feed hopper through the sealing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when the device is used to mix the raw materials, the geared motor is started through the stirring assembly. The geared motor drives the large gear and the spiral blade to rotate through the first rotating rod. When the large gear rotates, it drives the three sets of second rotating rods and stirring blades to rotate through the corresponding three small gears. The spiral blades and the three sets of second rotating rods and stirring blades work together to fully stir and mix the raw materials in the tank, which can improve the stirring and mixing effect of the raw materials in the tank.

[0016] In this invention, the dust collection component and the feeding component are used to activate the electric push rod when adding raw materials into the device. This causes the cover plate to flip open via the second rotating mounting base. Simultaneously, the centrifugal fan is activated, and the dust dust escaping from the feeding hopper during material addition is sucked up through the dust collection hood and connecting pipe. The dust is then sent into the dust collection bag. When the feeding is finished, the electric push rod is activated again, causing the cover plate to flip and close the feeding hopper, thus keeping the device in a closed state. This prevents raw material dust from being stirred up and entering the air during the mixing of raw materials, thus avoiding air pollution. Attached Figure Description

A dust collection hood 304 is installed on one side of the L-shaped plate 301. A connecting pipe 305 is installed on the top of the dust collection hood 304.

[0028] In this embodiment, as Figure 2 As shown, the mixing tank assembly 1 includes a tank body 101. An electric valve 102 and support legs 103 are installed at the bottom of the tank body 101. There are four support legs 103 in total, and the four support legs 103 are arranged in a ring with the vertical center line of the tank body 101 as the origin. The four support legs 103 can stably support the tank body 101. When the electric valve 102 is opened, the stirred raw materials in the tank body 101 can be discharged.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, the fixing plate 201 is installed on the top of the tank 101, the first rotating rod 204 is installed on the output end of the geared motor 203, and the spiral blade 207 forms a rotating mechanism with the geared motor 203 through the first rotating rod 204. When the geared motor 203 starts, it drives the large gear 206 and the spiral blade 207 to rotate through the first rotating rod 204. The spiral blade 207 can turn and mix the raw materials in the tank 101.

[0030] In this embodiment, as Figure 3 and Figure 4As shown, the large gear 206 and the small gear 208 are meshed together.
