Description

Technical Field

[0001] The utility model provides a crusher for masterbatch raw materials, and relates to the technical field of masterbatch production. Background Art

[0002] In the plastics industry, masterbatch is an important material that adds color and function to plastic products. Masterbatch crushers are widely used in the production of masterbatch. They can crush masterbatch particles into fine powder, improve the uniformity and stability of masterbatch, and thus ensure the consistency and quality of coloring.

[0003] The patent with the patent authorization announcement number CN217910610U discloses an airflow vortex pulverizer for preparing masterbatch. The patent allows the masterbatch to enter the inner cavity of the pulverizer body from the feed pipe. When the large masterbatch falls on the filter plate, it slides from the filter plate to the inner cavity of the positioning shell. The second motor drives the first stirring rod to rotate. The first stirring rod engages with the second stirring rod to rotate and simultaneously pulverizes the large masterbatch. The pulverized masterbatch slides back into the inner cavity of the pulverizer body through the triangular block. The pulverized masterbatch is input into the positioning shell through the connecting pipe. The second motor drives the blunt knife and the vortex fan to rotate. The wind generated by the vortex fan drives the masterbatch to move upward. While the masterbatch moves upward, the blunt knife pulverizes the masterbatch for the second time. However, the pulverizer provided by the patent still has shortcomings in actual use. After the masterbatch is pulverized for the first time, the masterbatch is easily accumulated in the funnel and forms a bridge phenomenon, and the masterbatch is difficult to be input into the positioning shell from the connecting pipe.

[0004] Therefore, it is necessary to provide a pulverizer for masterbatch raw materials that prevents masterbatch powder from bridging. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: A crusher for masterbatch raw materials, see Figure 1-Figure 5 As shown, it includes a support frame 1, a crushing box 101, a feed hopper 102, a discharge pipe 2, an electronic valve 201, a screen 3, a drive motor 5, a connecting shaft 6, a gear 7 and a crushing roller 8. The crushing box 101 is installed on the support frame 1 by welding. The feed hopper 102 is fixedly connected to the top of the crushing box 101 by welding. The bottom of the crushing box 101 is connected and communicated with the discharge pipe 2. The electronic valve 201 is installed on the discharge pipe 2 by bolt connection. Two connecting shafts 6 are rotatably arranged in the crushing box 101. The crushing roller 8 is sleeved on the connecting shaft 6 by welding. The connecting shafts 6 all penetrate to the outside of the crushing box 101, and one end of the two connecting shafts 6 that penetrate to the outside of the crushing box 101 is fixedly connected with gears 7 by key connection. The two gears 7 are meshed with each other. A driving motor 5 is installed on the side of the outer side of the crushing box 101 away from the gear 7 by bolt connection. The output shaft of the driving motor 5 is fixedly connected to a connecting shaft 6 through a coupling. A screen 3 for screening masterbatches of different sizes is slidingly arranged in the crushing box 101, and also includes a vibration component. A vibration component for knocking the box body and preventing material bridging is arranged on the crushing box 101.

[0026] See also Figure 3 and Figure 5 As shown, the vibration assembly includes four support plates 16 installed on both sides of the crushing box 101 by bolt connection, and a guide rod 17 is slidably arranged on each two support plates 16. The two guide rods 17 on the same side are symmetrical. The two guide rods 17 on the same side of the crushing box 101 are fixedly connected with a knocking plate 20 for knocking the crushing box 101 by welding. The two knocking plates 20 are symmetrically distributed on both sides of the crushing box 101. A stopper 18 is fixedly connected to the guide rod 17 by welding. The stopper 18 is located between the two support plates 16. A telescopic spring 19 is wound around the guide rod 17. The telescopic spring 19 is located between the stopper 18 and the support plate 16. A mounting frame 13 is installed on the side of the crushing box 101 by bolt connection. A servo motor 14 is installed on the mounting frame 13 by bolt connection. A cam 15 is fixedly connected to the output shaft of the servo motor 14 by bolt connection. The cam 15 contacts and cooperates with the guide rods 17 on both sides.

[0027] When the masterbatch raw material needs to be crushed, the masterbatch raw material is poured from the feed hopper 102 into the crushing box 101. At this time, the driving motor 5 is started to drive a connecting shaft 6 to rotate, and the connecting shaft 6 drives two gears 7 to mesh with each other, so that the two connecting shafts 6 drive the crushing rollers 8 to crush the masterbatch raw material. After crushing, the smaller particles fall directly from the screen 3, and the larger masterbatch particles remain on the screen 3. The larger masterbatch particles are driven by the screen 3 to slide out of the crushing box 101, and the larger masterbatch particles can be poured back into the feed hopper 102 for crushing. The crushed masterbatch falls into the bottom of the crushing box 101, and the color masterbatch is made to The masterbatch raw material leaks out from the discharge pipe 2; when the masterbatch raw material bridges the bottom of the crushing box 101, the servo motor 14 is started to drive the cam 15 to rotate, and the cam 15 intermittently contacts the guide rods 17 on both sides. When the cam 15 contacts the guide rods 17, it pushes the guide rods 17 on both sides to slide along the support plate 16 to the side away from each other. At this time, the guide rod 17 compresses the telescopic spring 19 through the block 18. When the cam 15 is separated from the guide rod 17, the telescopic spring 19 is reset and pushes the guide rods 17 on both sides to approach each other. The guide rod 17 drives the knocking plate 20 to quickly hit the outer wall of the crushing box 101, so that the material bridging inside the crushing box 101 is shaken off, so that the material can be discharged normally.

[0028] Example 2: Based on Example 1, refer to Figure 3 and Figure 4 As shown, it also includes a discharge barrel 10 rotatably arranged in the feed hopper 102. The discharge barrel 10 is a semi-cylindrical shape with a hollowed-out middle portion. After the discharge barrel 10 rotates 180 degrees, the material inside is poured into the crushing box 101, and the material on the upper portion of the discharge barrel 10 cannot be discharged, thereby achieving quantitative intermittent discharge. The two gears 7 are fixedly connected to the first fixed rod 9 by welding, and the side of the discharge barrel 10 is fixedly connected to the second fixed rod 11 by welding. A guide frame 12 is slidably arranged on the first fixed rod 9 and the two second fixed rods 11.

[0029] When the two connecting shafts 6 rotate through the meshing of the gears 7, the first fixed rod 9 on the gear 7 slides on the guide frame 12 and drives the guide frame 12 to move up and down. The guide frame 12 pushes the second fixed rod 11 to rotate the discharge barrel 10, so that the masterbatch raw materials in the discharge barrel 10 are intermittently discharged into the crushing box 101 to prevent the materials from accumulating in the crushing box 101.

[0030] See also Figure 2 and Figure 6As shown, it also includes a protective plate 21 installed on the support frame 1 by means of bolt connection, the protective plate 21 is located directly below the crushing box 101, a weighing plate 22 is installed on the protective plate 21 by means of bolt connection, a weight display 23 is installed on the front side of the protective plate 21 by means of bolt connection, and the weighing plate 22 and the weight display 23 are electrically connected.

[0031] After the masterbatch raw materials are crushed, the container is placed on the weighing plate 22. After the electronic valve 201 is opened, the crushed masterbatch raw materials fall into the container through the discharge pipe 2. At this time, the weighing plate 22 is used to weigh the contained materials, and the weighed quantity is displayed on the weight display 23, so as to carry out quantitative loading.

[0032] See also Figure 1 and Figure 2 As shown, a protective shell 4 is installed on the side of the crushing box 101 by bolt connection, and the driving motor 5 is located in the protective shell 4; a dustproof shell 24 is installed on the weight display 23 by bolt connection; and a baffle 25 is fixedly connected to the top edge of the feed hopper 102 by bolt connection.

[0033] The dustproof cover 24 can prevent dust from falling on the weight display 23 and making it difficult to clean, and can protect the weight display 23 from being damaged by collision; the baffle 25 can prevent the masterbatch raw materials from leaking out when adding the raw materials into the feed hopper 102, so that the raw materials can be fed better.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
