[0002] Polymer wax is a synthetic high molecular wax, including polyethylene wax (PE wax) and polypropylene wax (PP wax). Polymer wax is widely used in plastic and rubber processing industries. It is used as a lubricant and dispersant to improve the processing performance and surface quality of products. They are also used in masterbatches or functional masterbatches as dispersants, as well as in cable insulation materials and rubber processing as lubricants. In addition, polymer wax is also used in energy-saving agents for polyolefin resin processing and wear resistant agents for printing inks.

[0003] In the prior art, when preparing polymer wax fine powder, a grinder can be used to achieve the miniaturization of the wax material. When adding polymer wax to the grinder, if too much is added at one time, it is easy to cause the grinder to be blocked. Therefore, in order to reduce the occurrence of grinder blockage, the staff usually feeds the grinder manually and in small amounts multiple times. Although this method is effective, it also increases the workload of the staff.

[0004] Therefore, the present invention provides a device for preparing ultrafine polymer wax powder to solve the above problems. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a device for preparing ultrafine polymer wax powder, such as Figure 1 , Figure 3 and Figure 5 As shown, the preparation device includes a base plate 1, a grinder 2 fixedly mounted on the top of the base plate 1 for preparing polymer wax powder, a first mounting frame 3 fixedly mounted on the top of the base plate 1, and a feeding mechanism arranged on the first mounting frame 3 for feeding the grinder 2.

[0029] The feeding mechanism includes a feeding box 5, a discharge hopper 12 fixedly installed at the bottom of the feeding box 5, a guide plate 6 fixedly installed inside the feeding box 5, and a movable plate 7 arranged inside the feeding box 5. The top of the movable plate 7 is in contact with the bottom of the guide plate 6. Both sides of the movable plate 7 are fixedly connected with connecting columns 8. The connecting columns 8 pass through the feeding box 5. The feeding box 5 is provided with a strip groove for the connecting columns 8 to move.

[0030] The grinder 2 provided in the preparation device can grind polymer wax into ultrafine powder. When the preparation device is in use, the feed box 5 replaces the staff to add polymer wax to the grinder 2. The polymer wax is placed inside the feed box 5 before being ground into fine powder. The two guide plates 6 in the feed box 5 are tilted to facilitate the discharge of the polymer wax. The gap between the two guide plates 6 is the discharge port of the polymer wax. The size of the gap is changed by the movement of the movable plate 7, thereby realizing the control of the discharge amount. The opening of the strip groove provides a prerequisite for the sliding of the connecting column 8 and driving the movable plate 7 to move.

[0031] Further, in order to enable the movable plate 7 to move, as Figure 1 , Figure 3 and Figure 5 As shown, one side of the feed box 5 is rotatably connected to a bidirectional threaded rod 10, one end of the bidirectional threaded rod 10 is fixedly connected to a turntable 11, and the end of the connecting column 8 away from the movable plate 7 is fixedly connected to a threaded block 9, the threaded block 9 is screwed on the bidirectional threaded rod 10, and the side of the threaded block 9 close to the connecting column 8 is in contact with one side of the feed box 5.

[0032] The movement of the movable plate 7 is achieved by the rotating bidirectional threaded rod 10. The staff can manually rotate the turntable 11 to drive the bidirectional threaded rod 10 to rotate. The threaded block 9 screwed on the bidirectional threaded rod 10 can drive the movable plate 7 to move through the connecting column 8, thereby changing the size of the discharge port. The threaded block 9 is attached to the feed box 5, providing a stable guarantee for the movement of the movable plate 7.

[0033] Furthermore, in order to improve the feeding efficiency of the feeding box 5, as Figure 1 , Figure 2 and Figure 4 As shown, a mounting block 14 is fixedly connected to the first mounting frame 3 , a slide bar 15 is fixedly connected to the mounting block 14 , a connecting block 13 is fixedly connected to the feed box 5 , and the connecting block 13 is slidably connected to the slide bar 15 .

[0034] A rotating drum 21 is provided on one side of the feed box 5, and a guide drum 20 is fixedly connected inside the rotating drum 21, and a push rod 18 is rotatably connected inside the guide drum 20, and a moving column 19 is fixedly connected to the push rod 18. A pad 17 is fixedly connected to one end of the push rod 18, and a side of the pad 17 away from the push rod 18 is fixedly connected to one side of the feed box 5.

[0035] There are two guide cylinders 20, both fixed inside the rotating cylinder 21. There is a certain gap between the two guide cylinders 20, and the gap forms a circulating track. The moving column 19 on the push rod 18 is located in this track and fits with the inner wall of this track. When the rotating cylinder 21 rotates, the moving column 19 is squeezed by the inner wall of the circulating track, which can force the moving column 19 to move back and forth horizontally with the push rod 18.

[0036] The push rod 18 is connected to the feed box 5 through the pad 17 fixed thereto, so that when the push rod 18 moves, it can also drive the feed box 5 to move. This reciprocating movement creates a vibration effect. Since the polymer wax may also cause the feed box 5 to be blocked, this vibration effect can improve the discharge efficiency of the polymer wax inside the feed box 5 and reduce the possibility of polymer wax being blocked inside the feed box 5.

[0037] Connecting blocks 13 are fixed on both sides of the feed box 5, and two slide rods 15 are provided. When the push rod 18 drives the feed box 5 to move, the connecting block 13 can slide on the slide rod 15 along with the feed box 5. Through the setting of the slide rod 15, the stability of the feed box 5 during operation can be effectively improved.

[0038] In order to allow the polymer wax to enter the grinder 2, Figure 1 , Figure 2 and Figure 3 As shown, a conveying plate 23 is provided directly below the discharge hopper 12 , and the conveying plate 23 is fixedly connected to the first mounting frame 3 .

[0039] The polymer wax can fall onto the feed plate 23 through the discharge hopper 12 through the vibration effect of the feed box 5. The feed plate 23 is arranged at an angle, and the lower end of the feed plate 23 is located at the top of the feed inlet of the grinder 2. This arrangement allows the polymer wax that falls onto the feed plate 23 to automatically fall into the grinder 2 under the action of gravity.

[0040] It should be noted that in order to reduce the wear between the connecting block 13 and the sliding rod 15, Figure 1 , Figure 2 and Figure 6 As shown, a spring 16 is sleeved on the slide bar 15 , one end of the spring 16 is fixedly connected to the mounting block 14 , and the other end of the spring 16 is fixedly connected to the connecting block 13 .

[0041] When the feed box 5 and the connecting block 13 move on the slide rod 15, the spring 16 can be compressed. After the feed box 5 and the connecting block 13 are reset, the spring 16 will also be released. The setting of the spring 16 can play a good buffering effect when the feed box 5 and the connecting block 13 move, so that the connecting block 13 will not slide too stiffly on the slide rod 15, and it can also help reduce the wear between the connecting block 13 and the slide rod 15.

[0042] Furthermore, in order to enable the drum 21 to rotate, Figure 1 , Figure 3 and Figure 4 As shown, the second mounting frame 4 is fixedly connected to the first mounting frame 3 , the top of the second mounting frame 4 is fixedly connected to a motor 22 , and the output end of the motor 22 is fixedly connected to an end of the rotating drum 21 away from the pad 17 .

[0043] The motor 22 is mounted on the second mounting frame 4 , which provides stability for its own operation. After the motor 22 is started, the output end of the motor 22 can directly drive the drum 21 to rotate, thereby helping to improve the unloading effect of the feed box 5 .

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
