Description

Technical Field

[0001] The present application relates to the field of material pulverization, and in particular to a forced-feed pulverizer. Background Art

[0002] In some production or recycling processes, a crusher is needed to crush larger volumes of raw materials into smaller volumes for subsequent transportation and processing.

[0003] The existing plastic shoe last crusher and shoe last crushing production line, with announcement number CN205438975U, features raw materials placed into a feed bin and falling into a crushing chamber. The chamber houses a rotating blade shaft with a fixed moving blade mounted on it, and a fixed blade fixed to the inner wall of the crushing chamber. The moving blade shears and crushes the raw materials as it passes the fixed blade, and material that reaches a certain volume falls through a screen below the crushing chamber.

[0004] Regarding the above-mentioned related technologies, the raw materials are prone to bounce when the movable knife and the fixed knife are shearing, which makes the raw materials unable to be effectively crushed and reduces the crushing efficiency. At the same time, the frequent bouncing of the raw materials causes the force of the rotating movable knife to vary greatly, the load is unstable, and the service life of the equipment is reduced. Summary of the Invention

[0005] In order to improve the crushing efficiency and extend the service life of the equipment, the present application provides a forced feeding crusher.

[0006] The present application provides a forced-feed pulverizer that adopts the following technical solution.

[0007] A forced-feed crusher comprises a feed box for placing raw materials to be crushed, a crushing body connected to the feed box and crushing the raw materials fed into the feed box, the feed box is rotatably connected to a pressure roller on one side of the interior of the crushing body, the feed box is provided with a pressure motor for rotating the pressure roller, and several rows of cylinder parts are fixedly connected to the circumferential surface of the pressure roller, and each row of cylinder parts is provided with several cylinder parts along the axis direction of the pressure roller, and adjacent rows of cylinder parts are staggered, the pressure roller feeds the raw materials to one side of the feed box and the knife shaft of the crushing body drives the raw materials away from the feed box to align them.

[0008] By adopting the above technical solution, the rotating cylinder presses the raw materials into the crushing body, thereby reducing the possibility of the raw materials jumping during the rotating shearing process of the movable knife of the crushing body, so that the crushing body can effectively crush the raw materials, and the load of the crushing body during shearing remains stable, reducing vibration, and thus improving the service life of the equipment.

[0009] Optionally, each of the cylinders is fixedly connected to a claw piece at one end away from the pressing roller, the claw piece and the cylinder are arranged at an angle, and the end of the claw piece away from the cylinder is the front end of the claw piece in the rotation direction.

[0010] By adopting the above technical solution, the inclined claws can effectively press the raw materials into the crushing body to further improve the shearing efficiency.

[0011] Optionally, the rotation direction of the pressing roller is the same as the rotation direction of the blade shaft of the crushing body. An auxiliary roller is connected to the feed box and rotates in the opposite direction to the pressing roller. The auxiliary roller is provided with an auxiliary claw that is consistent with the structure and combination of the cylinder and the claw piece. The auxiliary roller is close to the pressing roller to drive the raw material away from one side of the crushing body. The auxiliary roller can be driven to rotate by the pressing motor.

[0012] By adopting the above technical solution, when a large amount of raw materials are put in, the rotating movable knife in the crushing body cannot crush all the raw materials fed by the pressing roller in time, and a part of the raw materials will move to the vicinity of the claw piece and the movable knife of the crushing body. At this time, the rotation of the claw piece will tend to bring the raw materials out of the crushing body and back to the feed box, and the movement directions of the nearby claw piece and the movable knife of the crushing body are opposite, so that the movable knife of the crushing body is prone to bear a certain unnecessary load at this time. The existence of the auxiliary roller can, on the one hand, reduce the raw materials brought back to the feed box by the claw piece, and on the other hand, it can also reduce the unnecessary load borne by the movable knife of the crushing body.

[0013] Optionally, one end of the pressing roller is coaxially fixedly connected to a roller shaft rotatably connected to the outer wall of the feed box, and the output shaft of the pressing motor is coaxially fixedly connected to a driving sleeve sleeve mounted on the roller shaft, and a number of insertion rods are evenly arranged inside the driving sleeve around the rotation axis of the roller shaft, and the insertion rods are radially inserted into the roller shaft along the driving sleeve, and an insertion rod spring is provided inside the driving sleeve corresponding to each insertion rod, and the insertion rod spring forces the insertion rod to be inserted into the roller shaft, and the insertion rod is inserted into one end of the roller shaft in a hemispherical shape.

[0014] By adopting the above technical solution, when there is a lot of raw materials or the volume of the raw materials is too large, and the crushing body cannot crush the raw materials into materials that can fall from the screen of the crushing body in time, the continued rotation of the driving sleeve will cause the insertion rod to separate from the roller shaft, so that the pressing roller is not easily driven to rotate at this time, so that the pressure in the crushing body and the load borne by the movable knife of the crushing body are not too large, which can play a certain protective role for the equipment.

[0015] Optionally, the driving sleeve is slidably connected to a plurality of adjusting rods, each adjusting rod can abut against an end of an insertion rod spring away from the insertion rod, and the feed box is provided with an adjusting electric cylinder for adjusting the distance between the adjusting rod and the insertion rod.

[0016] By adopting the above technical solution, the maximum pressure value of the claws pressing the raw materials into the crushing body can be adjusted as needed, so as to better and more efficiently crush different raw materials to be crushed.

[0017] Optionally, the power rod of the adjusting electric cylinder is fixedly connected to a push ring, and a ring bevel is formed on the periphery of the inner circle of one end of the push ring. The end of the adjusting rod away from the insertion rod is fixedly connected to a rod wedge block that can be exposed from the driving sleeve, and the ring bevel can abut against the rod wedge block to make the rod wedge block move toward the insertion rod.

[0018] By adopting the above technical solution, the movement of the push ring can adjust all the rod wedges synchronously, which is more convenient.

[0019] Optionally, the driving sleeve is detachably connected to a sleeve end piece capable of abutting against an end of the push ring away from the ring inclined surface.

[0020] By adopting the above technical solution, it is ensured that the ring bevel can effectively abut against the rod wedge, so that under normal circumstances, the driving sleeve can effectively drive the roller shaft to rotate.

[0021] Optionally, the push ring includes a fixed ring fixedly connected to the power rod of the adjusting electric cylinder, a movable ring connected to the fixed ring and rotatable around the axis of the roller shaft and provided with a ring bevel, and each rod wedge block is formed with an inclined slide corresponding to the ring bevel, and the rod wedge block is slidably connected to the inclined slide.

[0022] By adopting the above technical solution, it is less likely that there will be significant wear between the rod wedge and the ring bevel, and when the ring bevel is installed corresponding to the rod wedge, even if the rod wedge does not enter the bevel slide correctly, the movable ring can be rotated to allow the rod wedge to enter the bevel slide.

[0023] Optionally, the insertion rod spring is inserted into the adjustment rod so that the adjustment rod can abut against the insertion rod.

[0024] By adopting the above technical solution, when the adjusting rod abuts against the inserting rod, the inserting rod is not easy to separate from the roller shaft, so that the driving sleeve can effectively drive the roller shaft to rotate, so that the harder raw materials can be forcibly crushed when needed.

[0025] Optionally, the opening of the roller shaft for the insertion rod to be inserted is a waist groove, and the length direction of the waist groove is consistent with the direction of the rotation axis of the roller shaft.

[0026] By adopting the above technical solution, when a certain offset occurs between the roller shaft and the driving sleeve along the axis of the roller shaft, the inserted rod will not fall out of the waist groove, so that the roller shaft can effectively rotate with the driving sleeve.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. Reduce the possibility of raw materials jumping during the rotating shearing process of the crushing body's moving knife, so that the crushing body can effectively crush the raw materials, and keep the load of the crushing body stable during shearing, reduce vibration, and thus extend the service life of the equipment;

[0029] 2. The inclined claws can effectively press the raw materials into the crushing body to further improve the crushing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] The first embodiment of the present application discloses a forced feeding pulverizer, referring to Figure 1 , including a feed box 1 for materials to be put into from the upper opening, the bottom of the feed box 1 is detachably connected to a crushing body 2, and the crushing body 2 can be composed of the existing crushing chamber, knife shaft, movable knife, fixed knife and screen in the background technology, so that the material in the feed box 1 falls into the crushing body 2 for crushing.

[0038] Reference Figure 1 and Figure 2The inner wall of the bottom of the feed box 1 is rotatably connected to a press roller 3. The axis direction of the press roller 3 is the same as the axis direction of the blade shaft of the crushing body 2. The rotation direction of the press roller 3 is the same as the rotation direction of the blade shaft of the crushing body 2. A press motor 4 is fixedly connected to the outside of the feed box 1. The press motor 4 can be a reduction motor to drive the press roller 3 to rotate. The side of the press roller 3 that rotates from top to bottom is aligned with the side of the blade shaft of the crushing body 2 that rotates from top to bottom. The circumferential surface of the press roller 3 is evenly connected with several rows of cylinder pieces 5 around its own axis. The cross-section of the cylinder piece 5 can be T-shaped, so that the cylinder piece 5 is not easily deformed during the process of contacting the raw material and pressing it into the crushing body 2. Several cylinder members 5 are evenly arranged in each row along the axis direction of the pressing roller 3, and the two adjacent rows of cylinder members 5 are staggered so that more cylinder members 5 can be arranged on the pressing roller 3. Each cylinder member 5 is fixedly connected to a claw piece 51 at one end away from the pressing roller 3. The claw piece 51 and the cylinder member 5 are inclined. The side of the claw piece 51 away from the cylinder member 5 is the front end of the claw piece 51 when it rotates around the axis of the pressing roller 3, so that during the rotation of the pressing roller 3, the claw piece 51 can effectively press the raw material into the crushing body 2.

[0039] The implementation principle of a forced-feed crusher in the first embodiment of the present application is as follows: the raw material is fed into the feed box 1, and the claw piece 51 and the cylinder 5 drive the raw material to be pressed downward into the crushing body 2 on the side of the pressing roller 3 away from the upper opening of the feed box 1, so that the raw material is continuously pressed into the movable knife of the crushing body 2 that rotates from top to bottom, so that the raw material is efficiently crushed.

[0040] Example 2:

[0041] The second embodiment of the present application discloses a forced feeding crusher, referring to Figure 3 , which is different from the first embodiment in that an auxiliary roller 52 is rotatably connected to the bottom of the feed box 1 or the upper part of the crushing chamber of the crushing body 2, and the auxiliary roller 52 is located between the bottom of the pressing roller 3 rotating from bottom to top and the top of the knife shaft of the crushing body 2 rotating from top to bottom. The direction of the rotation axis of the auxiliary roller 52 is the same as the direction of the rotation axis of the pressing roller 3, and the rotation direction of the auxiliary roller 52 is opposite to the rotation direction of the pressing roller 3. The output shaft of the pressing motor 4 can be connected to a dual-output shaft reduction gearbox so that the pressing motor 4 can drive the pressing roller 3 and the auxiliary roller 52 to rotate at the same time. Several auxiliary claws 53 are fixedly connected to the circumferential surface of the auxiliary roller 52. The structural setting of the auxiliary claws 53 is consistent with the structure formed by the combination of the cylinder 5 and the claw piece 51, so that when the pressure roller 3 rotates and the claw piece 51 brings a part of the raw materials on the upper part of the crushing body 2 into the feed box 1, the reverse rotation of the auxiliary roller 52 can press a part of the raw materials into the crushing body 2 again, and can reduce the pressure on the movable knife of the crushing body 2 when it is moving from bottom to top, which helps to reduce the load on the knife shaft of the crushing body 2.

[0042] Reference Figure 4 One end of the pressing roller 3 is coaxially fixedly connected to a roller shaft 54 ​​exposed to the outer wall of the feed box 1. A number of waist grooves 45 are evenly opened on the circumferential surface of the roller shaft 54 ​​around its own axis. The length direction of each waist groove 45 is consistent with the axis direction of the roller shaft 54. The roller shaft 54 ​​is plugged and coaxially slidably connected with a driving sleeve 55. The inner wall of the driving sleeve 55 is slidably connected with an insertion rod 56 corresponding to each waist groove 45. The insertion rod 56 is inserted into the driving sleeve 55 along the radial direction of the position of the driving sleeve 55. One end of the insertion rod 56 located in the waist groove 45 is hemispherical, and a insertion rod spring 57 is placed in the driving sleeve 55 corresponding to each insertion rod 56. The insertion rod spring 57 forces one hemispherical end of the insertion rod 56 to tightly abut against the inner wall of the waist groove 45. An adjustment rod 58 is provided at the end of the plunger spring 57 away from the plunger 56. An opening is provided on the end of the adjustment rod 58 for insertion of the plunger spring 57, so that the adjustment rod 58 can abut against the plunger 56. A rod wedge 43, which is exposed from the drive sleeve 55, is fixedly connected to the end of the adjustment rod 58 away from the plunger spring 57. The rod wedge 43 can be slidably connected to the drive sleeve 55 synchronously with the adjustment rod 58. The end of the rod wedge 43 exposed from the drive sleeve 55 is arranged with an inclined surface.

[0043] Reference Figure 4 , the driving sleeve 55 is coaxially plugged with a push ring 41, and the push ring 41 includes a movable ring 47 and a fixed ring 46 that are coaxially connected. The fixed ring 46 is further away from the rod wedge 43 than the movable ring. The inner circle of the end face of the movable ring 47 away from the fixed ring 46 is formed with a ring bevel 42. The side of the ring bevel 42 away from the rod wedge 43 is close to the circumferential inner wall of the fixed ring 46. The ring bevel 42 corresponds to each rod wedge 43 and is formed with an inclined slide 48. The inclination direction of the inclined slide 48 is consistent with the inclination direction of the ring bevel 42, and the inclined surface of the rod wedge 43 slides against Connected to the inclined slide 48, the vertical outer wall of the feed box 1 can be fixedly connected to two adjusting electric cylinders 59, and the power rods of the two adjusting electric cylinders 59 are fixedly connected to the opposite sides of the fixed ring 46 one by one. The power rod of the adjusting electric cylinder 59 is connected to the position of the fixed ring 46 away from the dynamic ring 47, so that when the raw material to be crushed changes, the distance between the adjusting rod 58 and the insertion rod 56 can be adjusted, so that the force applied to the insertion rod 56 by the insertion rod spring 57 changes, so that the maximum pressure applied to the raw material by the claw piece 51 and the cylinder 5 can be changed accordingly.

[0044] Reference Figure 4 The outer circumferential wall of one end of the driving sleeve 55 away from the roller shaft 54 ​​is coaxially and detachably connected with the sleeve end piece 44. The sleeve end piece 44 can abut against the end surface of the fixed ring 46 away from the dynamic ring 47, so that when the dynamic ring 47 abuts against the sleeve end piece 44, the inclined slide 48 can always remain in abutment with the rod wedge 43, and during the normal crushing process, the fixed ring 46 will not abut against the sleeve end piece 44.

[0045] The implementation principle of a forced-feed crusher in Example 2 of the present application is as follows: on the one hand, the auxiliary rollers 52 and auxiliary claws 53 provided help to further improve the crushing efficiency of the raw materials; on the other hand, when the raw materials in the crushing body 2 are piled up too much and cannot be crushed in time, the torque required for the rotation of the pressing roller 3 gradually increases. When it increases to a certain value, the rod spring 57 is compressed so that the rod 56 can be separated from the waist groove 45, so that the rotation of the driving sleeve 55 at this time will not cause the roller shaft 54 ​​to rotate synchronously, so that the pressure in the crushing body 2 is not easy to be too large, thereby protecting the equipment.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
