Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a crushing device for plastic colorants. Background Technology

[0002] Plastics are high molecular weight compounds polymerized from monomers through addition or condensation reactions. Commonly known as plastics or resins, they can have their composition and shape freely changed. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin, and the basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Plastic colorants are used as raw materials in the plastics processing technology to beautify, decorate, facilitate identification, improve weather resistance, improve mechanical properties, and improve optical properties. When producing plastic colorants, the raw materials need to be crushed.

[0003] For example, the utility model disclosed in CN210097773U discloses a raw material crushing equipment for the production of plastic colorants. Although it crushes the raw materials of plastic colorants, the existing technology still has the following problems when used: the raw material is crushed unevenly, and the crushed plastic colorants are easy to clump together and stick to the discharge port, resulting in poor material discharge. Therefore, we propose a raw material crushing device for the production of plastic colorants. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a plastic colorant pulverizing device. Through the combination of a fixing block, limiting bolts, widened mounting plates, and strip-shaped mounting holes, personnel can replace the arc-shaped screen with an appropriate aperture size according to the required fineness of the raw material to be pulverized. The combination of a pulverizing drum and T-shaped steel blades reduces the pulverizing space in the pulverizing chamber, resulting in more uniform and fine pulverization of the plastic colorant through the arc-shaped screen. The combination of a spiral stirring rod and a stirring motor ensures continuous stirring during the discharge process inside the discharge hopper, reducing the likelihood of clumping or adhesion of the plastic colorant at the discharge port, which could lead to poor discharge.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a plastic colorant pulverizing device, comprising a device body, a support frame at the bottom of the device body, a pulverizing chamber inside the device body, a feed hopper at one side of the top of the pulverizing chamber, a pulverizing drum horizontally mounted on the inner wall of the pulverizing chamber, T-shaped steel blades mounted on the surface of the pulverizing drum by fixing bolts, one end of the central shaft of the pulverizing drum extending through the pulverizing chamber to the outside of the device body, a pulverizing motor mounted on one side of the device body, the drive shaft of the pulverizing motor being fixedly connected to the central shaft of the pulverizing drum, and a device at the bottom of the pulverizing drum. An arc-shaped screen is installed on the inner side of the main body. Slotted mounting holes are symmetrically opened on both sides of the main body. Widened mounting plates are fixedly installed on both sides of the arc-shaped screen. A fixing block is fixedly installed on the outer wall of the main body near the slotted mounting holes. Corresponding through holes are opened on the surfaces of the widened mounting plates and the fixing blocks. The widened mounting plates and the fixing blocks are fixed together by limiting bolts. A discharge hopper is fixedly installed on the surface of the main body at the bottom of the arc-shaped screen. A spiral stirring rod is horizontally installed on the inner side of the discharge hopper. A stirring motor is installed on one side of the outer wall of the discharge hopper. The drive shaft of the stirring motor is fixedly connected to the spiral stirring rod.

[0006] As a preferred embodiment of this utility model, four rows of T-shaped steel blades are arranged laterally on the surface of the crushing drum. The T-shaped steel blades are located on the outer surface of the crushing drum, and there are eight T-shaped steel blades in one row.

[0007] As a preferred technical solution of this utility model, an arc-shaped movable baffle is horizontally installed on the inner wall of the feed hopper located on one side of the top of the main body of the device.

[0008] As a preferred technical solution of this utility model, a limit stop is fixedly provided on one side surface of the widened mounting plate.

[0009] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0010] 1. By combining fixed blocks, limiting bolts, widened mounting plates, and strip-shaped mounting holes, personnel can replace the arc-shaped screen with the appropriate size of holes according to the required coarseness of the raw material crushing. By combining the crushing drum and T-shaped steel blades, the crushing space of the raw material in the crushing chamber is reduced, making the plastic colorant more uniform and fine after being crushed and passing through the arc-shaped screen. By combining the spiral stirring rod and stirring motor, the plastic colorant is continuously stirred during the discharge process inside the discharge hopper after being crushed, reducing the accumulation of plastic colorant at the discharge port or the sticking to the discharge port, which can cause poor discharge.

[0011] 2. By installing four rows of T-shaped steel blades on the outer surface of the crushing drum, the plastic colorant raw materials are fully crushed, improving the crushing and mixing efficiency; by installing an arc-shaped movable baffle horizontally on the inner wall of the feed hopper of the main body of the device, the raw materials are effectively prevented from splashing out of the bin during the crushing process.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0017] For an example, please refer to... Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a plastic colorant pulverizing device, including a device body 1, a support frame 10 at the bottom of the device body 1, a pulverizing chamber inside the device body 1, a feed hopper at one side of the top of the pulverizing chamber, a pulverizing drum 2 horizontally mounted on the inner wall of the pulverizing chamber, T-shaped steel blades 7 mounted on the surface of the pulverizing drum 2 by fixing bolts, one end of the central shaft of the pulverizing drum 2 extending through the pulverizing chamber to the outside of the device body 1, a pulverizing motor 6 mounted on one side of the device body 1, the drive shaft of the pulverizing motor 6 being fixedly connected to the central shaft of the pulverizing drum 2, an arc-shaped screen 3 mounted on the inner side of the device body 1 at the bottom of the pulverizing drum 2, strip-shaped mounting holes 15 symmetrically opened on both sides of the device body 1, widening mounting pieces 13 fixedly mounted on both sides of the arc-shaped screen 3, and fixing blocks 11 fixedly mounted on the outer wall of the device body 1 near the strip-shaped mounting holes 15, with corresponding through holes on the surfaces of the widening mounting pieces 13 and the fixing blocks 11. The plate 13 is fixed to the fixing block 11 by the limiting bolt 12. The bottom end of the arc-shaped screen 3 is fixedly equipped with a discharge hopper 5. A spiral stirring rod 8 is horizontally installed inside the discharge hopper 5. A stirring motor 9 is installed on the outer wall of one side of the discharge hopper 5.

Through the combination of the crushing drum 2 and the T-shaped steel blade head 7, the raw material crushing space in the crushing chamber is reduced, so that the plastic colorant is crushed and passes through the arc-shaped screen 3 more evenly and finely. Through the combination of the spiral stirring rod 8 and the stirring motor 9, the plastic colorant is continuously stirred during the discharge process inside the discharge hopper 5 after crushing, which reduces the accumulation of plastic colorant at the discharge port or the adhesion at the discharge port, which leads to poor discharge.

By installing four rows of T-shaped steel blades 7 on the outer surface of the crushing drum 2, the plastic colorant raw material is fully crushed, and the crushing and mixing efficiency is improved.

[0019] like Figure 1 , Figure 2 As shown, an arc-shaped movable baffle 4 is installed horizontally on the inner wall of the feed hopper on one side of the top of the main body 1 of the device; by installing the arc-shaped movable baffle 4 horizontally on the inner wall of the feed hopper of the main body 1 of the device, the raw materials are effectively prevented from splashing out of the bin during the raw material crushing process.

[0020] like Figure 3As shown, a limit stop 14 is fixedly installed on one side surface of the widened mounting plate 13; by fixing the limit stop 14 on one side surface of the widened mounting plate 13, improper operation during the replacement of the arc-shaped screen 3 can be avoided, which could cause one end of the arc-shaped screen 3 to slide into the inside of the crushing chamber.
