Description

Technical Field

[0002] Calcium zinc stabilizer is an additive widely used in the plastic processing process. Its main function is to stabilize the thermal stability and light stability of plastic materials. Calcium zinc stabilizer is usually synthesized by a special composite process with key ingredients such as calcium salt, zinc salt, lubricant, antioxidant, etc. Calcium zinc stabilizer is mainly used in the production of polyvinyl chloride (PVC) and other plastic products, such as food packaging materials, medical machinery, wire and cable materials, hard pipes, etc. The appearance of calcium zinc stabilizer is mainly milky white powder, block or mud. Among them, powdered calcium zinc stabilizer is the most widely used non-toxic PVC stabilizer;

[0003] Calcium salt and zinc salt are the core components of calcium zinc stabilizer, and they together constitute the basic skeleton of the stabilizer. These salts usually have excellent thermal stability and chemical stability. Common calcium salts include calcium carbonate, calcium stearate, etc., while zinc salts mainly include zinc stearate, zinc soap, etc. When processing calcium salt raw materials, the calcium salt raw materials are often ground. During the grinding process, the raw materials are crushed by grinding rollers to ensure that the mesh size of the ground raw materials is similar. However, in the actual operation process, due to the wide range of initial particle size distribution of the raw materials, that is, there are particles of different sizes, and this unevenness makes it difficult to quickly refine large particles during the grinding process, and small particles may have been over-ground, resulting in uneven particle size distribution of the final product.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-11 The present invention provides a technical solution: a calcium zinc stabilizer raw material uniform grinding device, comprising a grinding mechanism 2 fixedly installed inside a machine body 1, the grinding mechanism 2 comprising a main frame 201 connected to a power source, and a plurality of grinding rollers 3 for grinding the raw materials are installed on the main frame 201, wherein a plurality of scrapers are installed at the bottom of the main frame 201, when the power source drives the main frame 201 to rotate, the raw materials at the bottom of the machine body 1 will move upward under the action of the scrapers, and then the grinding rollers 3 grind the raw materials, and a feed bin 4 is fixedly installed on the side wall of the machine body 1 , and the discharge port of the feed bin 4 is connected with the interior of the machine body 1, and a screening mechanism 5 with changeable filter hole size is arranged inside the feed bin 4, the screening mechanism 5 performs size screening on the raw materials, and a scraper mechanism 6 is arranged inside the feed bin 4, and the scraper mechanism 6 is used to scrape off the bulk raw materials on the surface of the screening mechanism 5; and a transfer chamber 7 is installed on one side of the feed bin 4, and the transfer chamber 7 is located on the movement track of the scraper mechanism 6, wherein a grinding groove 101 for grinding bulk raw materials is arranged on the inner wall of the machine body 1, and a transfer channel 8 connected with the interior of the grinding groove 101 is installed at the bottom of the transfer chamber 7.

[0032] Furthermore, the grinding roller 3 in the present invention includes a roller 1 21 and a roller 22, wherein the roller 1 21 is located above the roller 22 and is used to grind large pieces of raw materials, and the roller 22 is used to grind small pieces of raw materials. A plurality of grinding stones 23 are installed inside the roller 1 21 and are slidably connected to the inner wall thereof, and one end of the grinding stone 23 is located outside the roller 1 21, and one end of the grinding stone 23 located outside the roller 1 21 is located in the grinding groove 101, so as to grind the large pieces of raw materials in the grinding groove 101, wherein the radius of the roller 1 21 is smaller than the radius of the roller 22, and the grinding stone 23 is located outside the roller 1 21. Figure 1-3 As shown, the raw material enters the body 1 through the feed bin 4. Since the radius of the roller 1 21 is smaller than the radius of the roller 2 22, and the distance between the roller 1 21 and the inner wall of the body 1 is larger than the distance between the roller 2 22 and the inner wall of the body 1, small pieces of raw material will fall from between the roller 1 21 and the body 1, most of the small pieces of raw material fall to the bottom of the body 1, and a small part falls between the roller 22 and the body 1, and then the roller 22 grinds the small pieces of raw material. The small pieces of raw material at the bottom of the body 1 will be lifted up by the action of the scraper, and the roller 22 grinds the small pieces of raw material during the movement, wherein the grinding stone 23 in the present invention cooperates with the grinding groove 101 to grind the large pieces of raw material, and then through the structural design of the present invention, the large pieces of raw material particles can be effectively ground, so that the large pieces of raw material particles are ground into small pieces, thereby avoiding the situation that large particles are difficult to refine and small particles are over-ground;

[0033] Further, the screening mechanism 5 includes a mounting frame 51 fixedly mounted inside the feed bin 4, and mounting plate racks 52 are fixedly mounted on both sides of the mounting frame 51, and a plurality of filter plates 1 53 and filter plates 2 54 are arranged between the mounting plate racks 52, and the filter plates 1 53 and filter plates 2 54 are arranged alternately in sequence, wherein the filter plates 2 54 are fixedly connected to the mounting plate rack 52, and a rubber pad 55 is arranged between the filter plates 1 53 and the mounting plate rack 52, and the cross-sections of the filter plates 1 53 and the filter plates 2 54 are both isosceles triangles, and the filter plates 1 53 and the filter plates 2 54 are installed on the mounting plate rack 52 in opposite states, and are fixed at both ends of the filter plate 1 53. A limited axis 56 is fixedly installed, and a sliding plate frame 57 slidably connected to the inner wall is installed inside both sides of the installation frame 51, and a plurality of heart-shaped grooves 571 are arranged on the sliding plate frame 57. The end of the limited axis 56 is located inside the heart-shaped groove 571 and slides within the heart-shaped groove. Both ends of the sliding plate frame 57 are magnetic surfaces. Both ends of each sliding plate frame 57 are provided with an electromagnet 58 fixedly connected to the inner wall of the installation frame 51. When one of the electromagnets 58 is energized, a repulsive force is generated on the magnetic surface of the sliding plate frame 57, and when the other electromagnet 58 is energized, the magnetic surface of the sliding plate frame 57 generates an attractive force. Then, combined with the attached Figure 6-9As shown, the filter plate 1 53 can be adjusted in position, and after the position of the filter plate 1 53 is adjusted, the distance between the filter channel formed between the filter plate 1 53 and the filter plate 2 54 changes. Figure 7 As shown in a, b and (c), the positional relationship between the filter plate 1 53 and the filter plate 2 54 is shown in the attached Figure 7 As shown in (b), when the filter plate 1 53 is adjusted upward, the distance between the filter channel of the filter plate 1 53 and the filter plate 2 54 is reduced, and it is used to filter smaller particles. When the filter plate 1 53 is adjusted downward, the distance between the filter channel of the filter plate 1 53 and the filter plate 2 54 is increased, and relatively larger raw material particles can be filtered, thereby achieving the purpose of flexibly adjusting the size of the screening raw material;

[0034] As mentioned above, when the raw materials fall onto the surfaces of the filter plates 1 53 and 2 54, small pieces of raw materials pass through the filtering channel between the filter plates 1 53 and 2 54, while large pieces of raw materials are intercepted on the surfaces of the filter plates 1 53 and 2 54 to achieve screening. When the distance between the filter plates 1 53 and 2 54 needs to be adjusted, one of the electromagnets 58 can be energized to adjust the spacing between the filter plates 1 53 and 2 54. Fig. 9 As shown, at this time, the filter plate 53 is at the lowest point (as shown in the attached Figure 7 As shown in FIG. 7( c ) in the figure, the sliding plate frame 57 makes a directional movement, and then the heart-shaped groove on the sliding plate frame 57 acts on the limiting shaft 56, so that the filter plate 1 53 can move upward, and during the ascending process of the filter plate 1 53, the filter channel spacing between the filter plate 1 and the filter plate 2 54 is reduced, and then through the structural design of the present invention, the filter channel spacing between the filter plate 1 53 and the filter plate 2 54 can be effectively changed.

[0035] The large raw material particles on the surface of the filter plate 1 53 and the filter plate 2 54 are processed by the scraper mechanism 6, so that the large raw material particles enter the transfer chamber 7 and are transported to the grinding tank 101 through the transfer channel 8; as a further limitation in the present invention, the scraper mechanism 6 includes a silicone scraper 61 arranged inside the feed, and the bottom of the silicone scraper 61 contacts the surface of the filter plate 1 53 and the filter plate 2 54, and a support frame 62 is fixedly installed on the silicone scraper 61, and sliding shafts 63 are fixedly installed at both ends of the support frame 62, and limiting grooves 64 for limiting the movement trajectory of the sliding shaft 63 are arranged on the inner walls of both sides of the feed bin 4, and the limiting grooves 64 include a straight groove 641, a trapezoidal groove 642 and a guide plate frame 643, wherein the guide plate frame 643 is installed at the intersection of the straight groove 641 and the trapezoidal groove 642, one side of the guide plate frame 643 is an inclined surface, and the other side is a right-angle surface, combined with the attached Fig.11As shown, the guide plate frame 643 is fixedly installed at the intersection of the straight trough body 641 and the trapezoidal trough body 642 close to the transfer chamber 7, one side of the straight trough body 641 is an inclined surface, and the side of the intersection of the straight trough body 641 and the trapezoidal trough body 642 is a right-angle surface; a winding mechanism 41 is installed on one side of the feed bin 4, and a reeling mechanism 42 is installed on the other side, and a servo motor 43 is fixedly installed at the output end of the winding mechanism 41, the same rope body 44 is wound between the winding mechanism 41 and the reeling mechanism 42, and the support frame 62 is fixed on the rope body 44, and a leaf spring 421 is fixedly installed at the output end of the reeling mechanism 42.

[0036] As described above, the servo motor 43 is started, and its output end drives the winding mechanism 41 to rotate, so as to pull the support frame 62 to move in a directional manner under the action of the rope body 44. During the movement of the support frame 62, the sliding shaft bodies 63 on both sides thereof will move along the trajectory of the straight groove body 641. During the movement, the sliding shaft body 63 passes through the inclined surface of the guide plate frame 643. It should be noted that the sliding shaft body 63 in the present invention is a telescopic shaft body, and then the support frame 62 drives the silicone scraper 61 to act on the large pieces of raw materials on the surfaces of the filter plate 1 53 and the filter plate 2 54, so that the large pieces of raw materials enter the transfer chamber 7 and enter the grinding groove 101 along the transfer channel 8. The winding mechanism 41 drives the rope body 44 When winding, the unwinding mechanism 42 will rotate under the action of the rope body 44, and the output end on the unwinding mechanism 42 will cause the leaf spring 421 to change, and then when the servo motor 43 rotates in the opposite direction, the leaf spring 421 will drive the unwinding mechanism 42 to rotate in the opposite direction to wind up the rope body 44, so that the support frame 62 drives the silicone scraper 61 to reset. During the resetting process, the support frame 62 moves along the straight area trajectory under the action of the sliding shaft 63, and when the sliding shaft 63 moves to the guide plate frame 643, the sliding shaft 63 will enter the trapezoidal groove 642 under the action of the right-angle surface of the guide plate frame 643, and finally return to the initial end of the straight groove 641.

[0037] The large pieces of raw material entering the grinding tank 101 will be ground into small particles by the grinding stone 23, and the small particles of raw material will be ground under the action of the roller 22, so as to avoid the situation that large particles are difficult to refine and small particles are over-ground. If there are small particles of raw material falling into the grinding tank 101, the small particles of raw material will fall to the bottom of the frame along the trajectory of the grinding tank 101, and the large particles of raw material will be ground into small particles by the grinding stone 23 in the grinding tank 101. The grinding number requirement requires that the distance between the grinding stone 23 and the grinding groove 101 needs to change accordingly, and the present invention makes the following design for this: a cavity 24 is opened inside the roller 21, and a guide shaft 25 is fixedly installed inside the cavity 24, and a movable sleeve 26 slidably connected to the outer wall of the guide shaft 25 is installed on the guide shaft 25, a constant force spring 27 is connected between the bottom of the movable sleeve 26 and the inner wall of the bottom of the cavity 24, and the top of the movable sleeve 26 is a magnetic surface, and an electric magnetic group 241 is fixedly installed on the top of the cavity 24, and the electric magnetic When the group 241 is energized, an attraction force is generated on the magnetic surface at the top of the movable sleeve 26. A plurality of reset springs 28 are connected between one end of the grinding stone 23 located inside the cavity 24 and the inner wall of the cavity 24, and an annular magnetic plate 29 is fixedly installed at the end of the grinding stone 23 away from the outside, wherein a plurality of force magnetic plates 261 are fixedly installed on the movable sleeve 26, and the plurality of force magnetic plates 261 are installed on the movable sleeve 26 at equal distances from the top to the bottom, and the magnetic strength of the force magnetic plates 261 increases from the top to the bottom, and the force magnetic plates 261 and the annular magnetic plates 29 are fixedly installed on the movable sleeve 26. The magnetic poles of the annular magnetic plate 29 are the same, and in actual operation, the electric magnetic group 241 can be energized to generate an attractive force on the magnetic surface on the top of the movable sleeve 26, thereby controlling the directional movement of the movable sleeve 26 on the guide shaft 25, so that the magnetic force of the force magnetic plate 261 corresponding to the annular magnetic plate 29 on the grinding stone 23 is different, and then the movement distance of the grinding stone 23 is changed, so that the distance between the grinding stone 23 and the grinding groove 101 can be effectively changed, so as to adapt to different types of raw materials and grinding mesh requirements.
