Description

Technical Field

[0001] The invention relates to the general field of crushing, grinding or pulverizing technology, and in particular to a raw material pulverizing device for production and processing of modified plastics. Background Art

[0002] In the production and processing of modified plastics, the raw materials need to be crushed by a crushing device, and the crushing device refers to the equipment for crushing various plastics and rubbers such as plastic profiles, tubes, rods, wires, films, and waste rubber products. The crushing device drives the belt and pulley through the motor, and moves the movable jaw through the eccentric shaft to achieve multiple crushing of the modified plastic raw materials by extrusion, rubbing and rolling. Technical enlightenment for raw material crushing devices; The following problems were found in the research of raw material crushing device: The raw material crushing device crushes the raw material by extrusion with the jaw plate. Since the jaw plate can usually only crush the modified plastic raw material once, it is easy to cause incomplete crushing, so that the raw material crushing device cannot crush the modified plastic raw material repeatedly while crushing it; At present, CN202310506539.3 in the prior art discloses a raw material crushing device for modified plastic production and processing. The vibration mechanism described in the invention is used to transmit power for the screening of the transmission mechanism while crushing the raw materials. By setting the vibration mechanism and the transmission mechanism, the crushed materials are screened while the raw materials are crushed, so that the smaller particles in the crushing process directly pass through the filter screen into the first collection box, and the larger flat fragments of raw materials will pass through the guide plate into the second collection box. After the crushing of this batch of raw materials is completed, the raw materials in the second collection box are put in together with the next batch of materials for secondary crushing. Combining the prior art and comparative documents, it can be learned that since the modified plastic raw materials have different sizes of particles after crushing, the modified plastic raw materials need to be screened later. After screening, the large particles of modified plastic raw materials usually need to be crushed again. Therefore, the screen cannot cut the modified plastic raw materials during the screening process, and the inside of the screen is usually prone to internal blockage due to the different sizes of the modified plastic raw materials after crushing, resulting in the raw material crushing device being unable to avoid internal blockage of the screen; The present invention can mainly solve the problem that the screen of the raw material crushing device cannot cut the modified plastic raw material during the screening process.

[0007] Furthermore, the transmission wheel passes through the upper end of the base, and the transmission wheel drives the movable jaw to swing left and right.

[0008] Furthermore, the movable jaw is inclined at 25-45 degrees, the lower end of the movable jaw is spaced 1-3 cm from the lower end of the fixed jaw, and the fixed jaw is located on both sides of the movable jaw.

[0009] Furthermore, the lower ends of the fixed jaw plate and the movable jaw plate are provided with side plates, the inner sides of the side plates are slidably connected with slide rods, pressure plates are swingably connected between the slide rods, a clamping ring is provided in the middle of the pressure plate, and a through shaft passes through the inside of the clamping ring.

[0010] Furthermore, the side plates are grouped into two each, a sliding groove is provided on one side of the side plate close to the sliding rod, the sliding rod slides inside the sliding groove, and the sliding grooves are evenly arranged horizontally.

[0011] Furthermore, the slide bar is matched with the pressing plate, and the slide bar is arranged vertically; Furthermore, the pressure plates are grouped into four pieces, and each group of pressure plates is in an "X" shape as a whole. The pressure plates in each group are tilted and swung through the retaining rings and through bearings, and the pressure plates swing on the sides of the side plates through the sliding rods.

[0012] Furthermore, the through shaft is in the shape of a workpiece, and the clamping rings are distributed at both ends of the outer side of the through shaft. The clamping rings swing in a circular ring shape on the outer side of the through shaft, and the pressure plates are located at both ends of the clamping rings.

[0013] Furthermore, a sieve plate is provided at the lower end of the base, and a rotating shaft is rotated through the inside of the sieve plate. Blades are surrounded on the outer sides of the upper and lower ends of the rotating shaft. A protrusion is arranged at the end of the blade close to the sieve plate, and a sliding cone is slidably nested and connected to the end of the protrusion close to the sieve plate.

[0014] Furthermore, the sieve plate is in a "V" shape, with holes running through the interior of the sieve plate, the hole diameter is 0.3-0.8 cm, and the sieve plate is located below the movable jaw plate and the fixed jaw plate.

[0015] Furthermore, the rotating shaft is located in the middle of the sieve plate, and the blades rotate 360 ​​degrees on the outside of the rotating shaft, and 5-7 blades are provided.

At this time, the pressure plate as a whole swings in a scissor-arm manner on the outside of the through-shaft through the retaining ring. By shortening the distance between the pressure plates, the modified plastic can be further crushed by the pressure plate when the distance between the movable jaw plate and the fixed jaw plate increases, thereby avoiding the situation where the modified plastic raw material falls to the lower end of the base without being completely crushed when the distance between the movable jaw plate and the fixed jaw plate increases. At the same time, this crushing equipment can extrude and crush when the movable jaw plate swings left and right, and at the same time, the modified plastic raw material inside the base is quickly extruded and crushed left and right through the pressure plate.

[0018] 2. After the movable jaw plate and the fixed jaw plate are crushed, the modified plastic raw material falls to the upper end of the screen plate and passes through the screen plate in a "V" shape. After the modified plastic raw material falls to the upper end of the screen plate, the modified plastic raw material can slide down on both sides of the upper end of the screen plate. When the modified plastic raw material slides down, it is squeezed to one side of the blade. The blade can use the impact of the modified plastic raw material sliding down to rotate 360 ​​degrees through the rotating shaft; 3. During the rotation of the blade, the modified plastic raw materials on the surface of the screen plate can be further cut and crushed. At the same time, the blade can drive the convex block and the sliding cone to rotate synchronously, and the sliding cone can scrape the surface of the screen plate. The rotating cutting of the blade and the scraping of the sliding cone can prevent large particles of modified plastic raw materials from accumulating and clogging the upper end of the screen plate. Therefore, the modified plastic raw materials can be screened through the screen plate after crushing, and the modified plastic raw materials can be cut and crushed through the rotating operation of the blade and the sliding cone.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

When the two jaw plates are close to each other, the modified plastic raw material is crushed, and when the two jaw plates are separated, the modified plastic raw material smaller than the discharge port is discharged from the bottom; The movable jaw 103 is inclined at 25-45 degrees, the lower end of the movable jaw 103 is spaced 1-3 cm from the lower end of the fixed jaw 104, and the fixed jaw 104 is located on both sides of the movable jaw 103; The modified plastic raw material is placed on both sides of the movable jaw plate 103, and the motor 101 drives the movable jaw plate 103 to swing left and right through the transmission wheel 102. The movable jaw plate 103 swings toward one side of the fixed jaw plate 104. When the two jaw plates are close to each other, the modified plastic raw material is crushed. When the two jaw plates are separated, the modified plastic raw material smaller than the discharge port is discharged from the bottom, so that the modified plastic raw material can be squeezed and crushed. Example 2: Refer to the attached manual Figure 1-6 It can be seen that the difference between Example 2 and Example 1 is that the lower ends of the fixed jaw plate 104 and the movable jaw plate 103 are both provided with side plates 2, the inner sides of the side plates 2 are slidably connected with slide bars 202, and the pressing plates 201 are swingably connected between the slide bars 202, and the middle part of the pressing plates 201 is provided with a clamping ring 203, and the inside of the clamping ring 203 is penetrated by a through shaft 204; Wherein: the side plates 2, each two side plates 2 form a group, a sliding groove is opened on the side of the side plate 2 close to the sliding rod 202, the sliding rod 202 slides inside the sliding groove, and the sliding grooves are evenly arranged horizontally; When the movable jaw 103 is tilted and swung, the side plate 2 on one side of the movable jaw 103 swings synchronously, while the side plate 2 on the side of the fixed jaw 104 is in a stationary state; A slide bar 202, the slide bar 202 is matched with the pressing plate 201, and the slide bar 202 is arranged vertically; The pressing plates 201 are grouped in four, and each group of pressing plates 201 is in an "X" shape as a whole. The pressing plates 201 in each group are tilted and swung through the clamping ring 203 and the through bearing 204. The pressing plates 201 swing on the side of the side plate 2 through the sliding rod 202; Each group of pressing plates 201 is scissor-arm swung and operated, and the modified plastic raw material between the movable jaw plate 103 and the fixed jaw plate 104 can be squeezed and crushed through the operation between the pressing plates 201; The through shaft 204 is in the shape of a workpiece, and the snap rings 203 are distributed at both ends of the outer side of the through shaft 204. The snap rings 203 swing in a circular ring shape on the outer side of the through shaft 204, and the pressure plates 201 are located at both ends of the snap ring 203; The transmission wheel 102 drives the movable jaw 103 to swing obliquely. At this time, the distance between the movable jaw 103 and the fixed jaw 104 on one side of the base 1 is shortened, and the movable jaw 103 and the fixed jaw 104 can squeeze and crush the modified plastic raw material. The distance between the movable jaw 103 and the fixed jaw 104 on the other side of the base 1 is increased; The movable jaw 103 drives the side plate 2 to swing synchronously, and the side plate 2 is stretched to one end of the pressure plate 201 through the sliding rod 202. The sliding rod 202 slides inside the sliding groove of the side plate 2, and the side plate on the side of the fixed jaw 104 is in a stationary state. At this time, the pressure plate 201 as a whole is scissor-arm swung on the outside of the through-shaft 204 through the clamping ring 203. By shortening the distance between the pressure plates 201, when the distance between the movable jaw 103 and the fixed jaw 104 increases, the modified plastic can be further crushed by the pressure plate 201, so as to avoid the situation that the modified plastic raw material is not completely crushed and falls to the lower end of the base 1 when the distance between the movable jaw 103 and the fixed jaw 104 increases. At the same time, this kind of crushing equipment can be squeezed and crushed when the movable jaw 103 swings left and right, and at the same time, the modified plastic raw material inside the base 1 is quickly squeezed and crushed left and right by the pressure plate 201; Example 3: Refer to the attached manual Figure 3 , 7 -9 It can be seen that the difference between Example 3 and Example 1-2 is that a sieve plate 3 is provided at the lower end of the base 1, and a rotating shaft 301 is rotatably penetrated inside the sieve plate 3, and blades 302 are surrounded on the outer sides of the upper and lower ends of the rotating shaft 301, and a protrusion 303 is arranged at one end of the blade 302 close to the sieve plate 3, and a sliding cone 304 is slidably nested and connected to the end of the protrusion 303 close to the sieve plate 3; Among them: the sieve plate 3 is in a "V" shape, and there are holes running through the inside of the sieve plate 3, and the diameter of the holes is 0.3-0.8 cm. The sieve plate 3 is located below the movable jaw plate 103 and the fixed jaw plate 104; The sieve plate 3 is located below the movable jaw plate 103 and the fixed jaw plate 104, so the modified plastic raw material after being crushed by the movable jaw plate 103 and the fixed jaw plate 104 can fall to the upper end of the sieve plate 3; The sieve plate 3 is in a "V" shape. Through the shape setting of the sieve plate 3, after the modified plastic raw material falls to the upper end of the sieve plate 3, the modified plastic raw material can fall downward on both sides of the upper end of the sieve plate 3; A rotating shaft 301 and blades 302, wherein the rotating shaft 301 is located in the middle of the sieve plate 3, and the blades 302 are rotatable 360° on the outer side of the rotating shaft 301, and 5 to 7 blades 302 are provided; The convex block 303 and the sliding cone 304 are matched with multiple groups. The end of the sliding cone 304 away from the convex block 303 is in contact with the surface of the sieve plate 3. The convex block 303 and the sliding cone 304 are slidably nested in a vertical direction, and the sliding distance is 0.5-1 cm. Wherein: after the movable jaw plate 103 and the fixed jaw plate 104 are crushed, the modified plastic raw material falls to the upper end of the sieve plate 3, and passes through the sieve plate 3 in a "V" shape. After the modified plastic raw material falls to the upper end of the sieve plate 3, the modified plastic raw material can slide down on both sides of the upper end of the sieve plate 3. When the modified plastic raw material slides down, it is squeezed to one side of the blade 302. The blade 302 can use the impact of the modified plastic raw material sliding down to rotate 360 ​​degrees through the rotating shaft 301, which can refer to the rotation principle of the waterwheel; During the rotation of the blade 302, the modified plastic raw material on the surface of the sieve plate 3 can be further cut and crushed. At the same time, the blade 302 can drive the protrusion 303 and the sliding cone 304 to rotate synchronously, and the sliding cone 304 can scrape the surface of the sieve plate 3. The rotating cutting of the blade 302 and the scraping of the sliding cone 304 can prevent large particles of modified plastic raw material from accumulating and clogging the upper end of the sieve plate 3. Therefore, while the crushed modified plastic raw material can be screened by the sieve plate 3, the modified plastic raw material can be cut and crushed by the rotating operation of the blade 302 and the sliding cone 304.
