Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch grinding, in particular to a grinding device for masterbatch production. Background Art

[0002] Masterbatch is a new type of colorant specially used for polymer materials. It is composed of pigment or dye, carrier resin and additives. It evenly loads excess pigment or dye into the resin to form a pigment concentrate with higher coloring ability than the pigment itself. In some special cases, such as when the particle size of the masterbatch does not match the requirements of specific plastic processing equipment, grinding treatment is required.

[0003] Current grinding devices for masterbatch production have significant technical limitations, particularly in the critical post-grinding process. After the masterbatch is ground, there's a lack of a mechanism for directly screening the ground product. This lack not only affects the uniformity and consistency of the masterbatch particles, but can also result in a mixture of particles of varying sizes, leading to color unevenness and performance degradation during subsequent plastic processing. The lack of a direct screening step means the ground masterbatch can't immediately separate undesirable coarse or fine particles. These uneven particles are difficult to evenly disperse during subsequent mixing and processing, ultimately impacting the quality of the finished plastic product. Therefore, we propose a grinding device for masterbatch production. Utility Model Content

[0004] The purpose of the present utility model is to provide a grinding device for masterbatch production, so as to solve the significant technical limitations of the current grinding device for masterbatch production mentioned in the above background technology, especially in the key link after the grinding process, after the masterbatch is ground, there is a lack of a mechanism for directly screening the ground product. This lack not only affects the uniformity and consistency of the masterbatch particles, but may also cause the product to be mixed with particles of different sizes, and then cause problems such as uneven color and performance degradation in the subsequent plastic processing process. The lack of a direct screening step means that the masterbatch after grinding cannot be immediately separated from the coarse particles or fine powder that do not meet the requirements. These uneven particles are difficult to disperse evenly in the subsequent mixing and processing, which ultimately affects the quality of the finished plastic products.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a grinding device for masterbatch production, comprising a shell, a motor is fixedly installed at the center of the top of the shell, a grinding block is provided at the top of the center of the shell, a grinding seat is fixedly installed at the lower end of the grinding block in the interior of the shell, a hollow column is fixedly connected to the center of the bottom of the shell, a tapered sleeve is sleeved on the top of the outer wall of the hollow column, a sieve plate is fixedly installed on the bottom of the outer wall of the tapered sleeve, a reciprocating screw is provided at the center of the inner wall of the hollow column, and the top and bottom of the reciprocating screw are fixedly connected. The two ends of the cam are connected with the guide rails of the present invention, and the guide rails are connected with the guide rails at the bottom and the top of the cam are connected with the guide rails at the bottom.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The grinding device for masterbatch production is designed with a motor, a hollow column, a tapered sleeve, a screen plate, a reciprocating screw, a connecting rod, a nut sleeve, a connecting plate, a push rod, a spring and a support rod. When the motor is running, it not only drives the grinding block to grind the masterbatch, but also cleverly uses the connecting rod to convert the rotation of the grinding block into the rotation of the reciprocating screw through an innovative mechanical linkage mechanism, thereby driving the nut sleeve to move back and forth along the screw. In this process, the connecting plate and the push rod serve as key transmission components, converting the linear motion of the nut sleeve into a vertical reciprocating impact on the tapered sleeve. Since the tapered sleeve is fixed to the screen plate, the screen plate The screen plate is connected by an elastic support system composed of support rods and springs. This design enables the screen plate to vibrate effectively when impacted by the top rod. The vibration of the screen plate greatly promotes the screening effect of the masterbatch after grinding, making the particle size more uniform and consistent, effectively avoiding the problems of uneven color and performance degradation caused by particle agglomeration or unseparated particles that are too large or too small. After grinding the masterbatch, the grinding device can directly and efficiently complete the screening work, significantly improving the production quality and efficiency of the masterbatch, reducing the difficulty and cost of subsequent processing, and achieving significant technological progress and economic benefits.

The outer wall of the hollow column 5 is provided with vertical grooves 11 corresponding to the opposite sides of the two connecting plates 12. The opposite sides of the two connecting plates 12 respectively penetrate into the outside of the two vertical grooves 11. The top opposite sides of the two connecting plates 12 are fixedly connected with a push rod 13. The four corners of the top of the sieve plate 7 are fixedly connected with support rods 16. The bottom of the grinding seat 4 is provided with grooves 14 corresponding to the upper ends of the four support rods 16. The inner top of the groove 14 is fixedly connected with a spring 15.

[0016] The motor 2 is fixedly connected to an output shaft through the output end at the bottom thereof. The lower end of the output shaft passes through the interior of the housing 1 and is fixedly connected to the center of the top of the grinding block 3. The output shaft is driven by the motor 2 to rotate the grinding block 3. A grinding groove is provided at the center of the top of the grinding seat 4. The lower end of the grinding block 3 passes through the interior of the grinding groove. When the masterbatch enters the grinding groove, the grinding block 3 rotates to cause the masterbatch to rub against the inner wall of the grinding groove, thereby crushing the masterbatch, thereby achieving the grinding effect.

[0017] The upper end of the hollow column 5 passes through the interior of the grinding groove, the upper end of the connecting rod 9 set at the top passes through the outside of the hollow column 5 and is fixedly connected to the center of the bottom of the grinding block 3, and the lower end of the connecting rod 9 set at the bottom is movably connected to the bearing fixedly installed at the bottom center of the shell 1, ensuring the stability of the grinding block 3 when driving the reciprocating screw 8 to rotate.

[0018] The tops of the two push rods 13 are fixed with rubber heads, and the upper ends of the two rubber heads are in contact with the bottom of the tapered sleeve 6, so that the push rods 13 and the tapered sleeve 6 have a buffering effect when they collide.

[0019] The tops of the four support rods 16 respectively penetrate into the interior of the four grooves 14 and are fixedly connected to the bottoms of the four springs 15 respectively. The tops of both sides of the support rods 16 are fixedly connected with sliders 18. Slide grooves 17 are provided on both sides of the inner wall of the groove 14. The sliders 18 are slidably connected to the inner walls of the slide grooves 17, ensuring the stability of the support rods 16 during displacement.

[0020] Slide plates are fixedly connected to the bottom positions on both sides of the hollow column 5, one end of the slide plate is fixedly connected to the inner bottom of the shell 1, and discharge ports are provided at the bottom of both sides of the shell 1. A movable door is movably installed at the bottom position of the center of the front surface of the shell 1. The masterbatch after screening can be discharged from the discharge port through the slide plate, and the user can re-process the masterbatch remaining on the screen plate 7 by opening the movable door.

[0021] A feed hopper is provided at the center of the upper end of the shell 1. The bottom of the feed hopper is fixedly connected to a material guide pipe. The bottoms of both sides of the material guide pipe penetrate into the interior of the shell 1. The masterbatch is poured from the feed hopper and then guided into the grinding tank by the material guide pipe.

[0022] Working principle: When the motor 2 is started, the output shaft at its bottom drives the grinding block 3 to rotate at high speed in the grinding groove on the top of the grinding seat 4. At this time, the masterbatch fed through the feed hopper falls evenly into the grinding groove through the material guide pipe. As the grinding block 3 rotates, the masterbatch is subjected to strong shear force and friction force, and is gradually crushed and refined, thereby achieving the grinding effect. At the same time, the bottom of the grinding block 3 is connected to the reciprocating screw 8 through the connecting rod 9. When the grinding block 3 rotates, the reciprocating screw 8 also starts to rotate through the transmission action of the connecting rod 9. As the reciprocating screw 8 rotates, the nut sleeve 10 on its surface moves up and down along the screw under the push of the thread, thereby driving the connecting plates 12 and the push rod 13 on both sides to do vertical reciprocating motion in the vertical groove 11. When the rubber head on the top of the push rod 13 contacts and collides with the bottom of the tapered sleeve 6, due to the buffering effect of the rubber head, the impact The force is converted into the up and down vibration of the conical sleeve 6 and the screen plate 7. The screen plate 7 is connected to the groove 14 and the spring 15 at the bottom of the grinding seat 4 through the support rod 16. This elastic connection structure enables the screen plate 7 to maintain a certain stability when it is vibrated, and at the same time realizes the screening function. During the screening process, the fine masterbatch particles fall into the collection area below through the sieve holes of the screen plate 7, while the larger particles remain on the screen plate 7 and continue to be vibrated. Finally, the screened masterbatch particles slide through the sliding plates on both sides of the hollow column 5 to the discharge port at the bottom of the shell 1. The user can open the movable door to take out the screened masterbatch. If the larger particles remaining on the screen plate 7 need to be further processed, the motor 2 can be turned off, the movable door can be opened, and the residue on the screen plate 7 can be manually cleaned. The entire grinding and screening process is automated and continuous, which improves the production efficiency and product quality of the masterbatch.

[0023] In summary: the grinding device for masterbatch production, through the design of motor 2, hollow column 5, tapered sleeve 6, sieve plate 7, reciprocating screw 8, connecting rod 9, nut sleeve 10, connecting plate 12, push rod 13, spring 15 and support rod 16, when the motor 2 is running, not only drives the grinding block 3 to grind the masterbatch, but also cleverly uses the connecting rod 9 to convert the rotational motion of the grinding block 3 into the rotation of the reciprocating screw 8 through an innovative mechanical linkage mechanism, thereby driving the nut sleeve 10 to move back and forth along the screw. In this process, the connecting plate 12 and push rod 13 serve as key transmission components, converting the linear motion of the nut sleeve 10 into a vertical reciprocating impact on the tapered sleeve 6. The conical sleeve 6 is fixed to the sieve plate 7, and the sieve plate 7 is connected to the elastic support system composed of the support rod 16 and the spring 15. This design enables the sieve plate 7 to produce effective up and down vibrations when it is impacted by the top rod 13. The vibration effect of the sieve plate 7 greatly promotes the screening effect of the masterbatch after grinding, making the particle size more uniform and consistent, and effectively avoiding the color unevenness and performance degradation problems caused by particle agglomeration or unseparated particles that are too large or too small. After grinding the masterbatch, the grinding device can directly and efficiently complete the screening work, significantly improving the production quality and efficiency of the masterbatch, reducing the difficulty and cost of subsequent processing, and has significant technical progress and economic benefits.
