Description

Technical Field

[0001] This application relates to the field of crusher technology, and in particular to an auxiliary tooling for changing crusher pressure rollers. Background Technology

[0002] In the processing of oils and feed, roller crushers are one of the essential key pieces of equipment. Raw materials (such as soybeans, corn, wheat, etc.) are fed evenly between two pressure rollers. The two rollers rotate downwards relative to each other while maintaining a certain speed difference. A certain working gap is maintained between the two rollers. When the raw materials pass between the two rollers with the speed difference, they are torn and squeezed by the rollers to achieve the particle size required for the next process and are discharged from the roller crusher.

[0003] Currently, rollers are prone to damage after prolonged use and require frequent maintenance. When a roller is damaged, other mechanisms need to be dismantled before the roller and shaft head can be removed together for replacement. Roller replacement is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] Therefore, it is necessary to provide an auxiliary tooling for changing crusher pressure rollers that can separate the shaft head from the roller body and enable quick replacement of the roller body, thus achieving high replacement efficiency.

[0005] An auxiliary tooling for replacing a crusher pressure roller is disposed on a crusher roller, the crusher roller including a roller body and a mounting frame, the roller body being installed within the mounting frame; the auxiliary tooling for replacing the crusher pressure roller includes:

[0006] A transport mechanism includes a sliding guide rail, a height detection component, a scissor lift component, and a drive component. The sliding guide rail is detachably connected to the mounting frame along an axial direction perpendicular to the roller body, and extends out of the mounting frame. The scissor lift component is slidably connected to the sliding guide rail and is provided with a lifting member for supporting the roller body. The drive component is used to drive the scissor lift component to move up and down, thereby causing the lifting member to move in a direction closer to or away from the roller body. The height detection component is used to measure the height of the roller body within the mounting frame.

[0007] A limiting mechanism is detachably connected to the mounting frame and located between the end of the roller and the mounting frame. The limiting mechanism can abut against the end of the roller.

[0008] In one embodiment, the scissor lift assembly includes a first scissor arm and a second scissor arm, the first scissor arm and the second scissor arm being arranged crosswise, and the first scissor arm and the second scissor arm being hinged at the crosswise position.

[0009] In one embodiment, both the first scissor arm and the second scissor arm have a first end and a second end that are disposed opposite to each other.

[0010] The first end is provided with a pulley, which is slidably connected to the sliding guide rail; and / or, the second end is provided with a support roller, which can abut against the roller body, and the support roller forms the lifting member.

[0011] In one embodiment, the driving component includes a first adjusting shaft, a second adjusting shaft, and an adjusting rod. The first adjusting shaft is rotatably connected to the first scissor arm, and the second adjusting shaft is rotatably connected to the second scissor arm. Both the first adjusting shaft and the second adjusting shaft have threaded holes. The adjusting rod passes through the two threaded holes and is threadedly connected to the two threaded holes. The two threaded holes on the first adjusting shaft and the second adjusting shaft have opposite rotation directions.

[0012] In one embodiment, a limiting groove is formed on the side wall of the sliding guide rail, the extending direction of the limiting groove is parallel to the extending direction of the sliding guide rail, and the pulley is slidably disposed in the limiting groove.

[0013] In one embodiment, the limiting mechanism includes a housing, a limiting member, and a resetting member. The housing has a receiving cavity and a through hole. The limiting member is housed in the receiving cavity and can move axially along the through hole to extend out of the housing and abut against the end of the roller. The resetting member is disposed between the limiting member and the housing and is used to provide a resetting force to keep the limiting member in its initial state.

[0014] In one embodiment, the limiting mechanism further includes a rotating disk and a handle connected to the rotating disk. The housing has a rotating groove and a notch in the rotating groove. The rotating disk is rotatably engaged in the rotating groove. The handle is rotatably provided with the notch and can abut against the two ends of the rotating groove that form the notch. A rotating boss is provided on the side of the rotating disk near the housing that abuts against the limiting member. The rotating boss is accommodated in the receiving cavity.

[0015] The handle has a first abutting position and a second abutting position; in the direction in which the handle rotates from the first abutting position to the second abutting position, the height of the rotating boss gradually increases.

[0016] In one embodiment, the limiting mechanism further includes a magnetic base and a magnetic component. The magnetic component is disposed on the side of the rotating disk away from the housing, and the magnetic base is connected to the side of the housing close to the rotating disk. When the handle is rotated to the second abutment position, the magnetic base guides the magnetic component to generate a magnetic attraction force.

[0017] In one embodiment, the height detection component includes an adjustment seat, a height gauge, and a locking member. The adjustment seat is connected to one side of the sliding guide rail and has a connection hole. The height gauge is movably disposed in the connection hole and can move in a direction perpendicular to the sliding guide rail. It can be locked by the locking member to fix the position of the height gauge relative to the adjustment seat.

[0018] In one embodiment, the mounting bracket is provided with a wedge-shaped buckle, and one end of the sliding guide rail is formed with an inclined surface, which engages with the wedge-shaped buckle.

[0019] And / or, a fixing seat is provided on the side wall of the mounting bracket, and a fixing buckle and fastener are provided at the bottom of the sliding guide rail. The fixing buckle is disposed opposite to the fixing seat and is fastened by the fastener.

[0020] In the above solution, by detachably mounting the transport mechanism and the limiting mechanism on the mounting frame, quick installation and disassembly are facilitated, improving the efficiency of roller replacement. By sliding the scissor lift assembly on the sliding guide rail, the scissor lift assembly can be moved directly below the roller, and the drive component can drive the scissor lift assembly to rise, allowing the lifting component to support the roller. The limiting mechanism abuts against the end of the roller to limit its movement, thus separating the shaft head from the roller. The height detection component can detect the height of the roller within the mounting frame. When replacing a new roller, the height and position of the new roller are adjusted using the height detection component and the scissor lift assembly, allowing for the installation of the shaft head and the new roller. This application enables the separation of the shaft head from the roller and allows for rapid roller replacement with high efficiency. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] For the above issues, please refer to Figure 1 and Figure 9This application relates to an auxiliary tooling 10 for replacing the pressure roller of a crusher, which is configured on a crushing roller 100. The crushing roller 100 includes a roller body 110, a shaft end, and a mounting frame 120, with the roller body 110 mounted inside the mounting frame 120. Specifically, the mounting frame 120 has two opposing side walls, with the roller body 110 disposed between the two side walls. Mounting holes 121 are provided on both side walls, and the shaft end is connected to the end of the roller body 110 through the mounting holes 121, with the shaft end located outside the mounting frame 120.

[0045] The crusher pressure roller replacement auxiliary tooling 10 includes a transport mechanism 200 and a limiting mechanism 300. Both the transport mechanism 200 and the limiting mechanism 300 can be detachably connected to the mounting frame 120, which facilitates the quick installation and removal of the transport mechanism 200 and the limiting mechanism 300 and can improve the efficiency of replacing the roller body 110.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The transport mechanism 200 includes a sliding guide rail 210, a height detection component 220, a scissor lift component 230, and a drive component 240. The sliding guide rail 210 is detachably connected to the mounting frame 120 along an axial direction perpendicular to the roller body 110, and the sliding guide rail 210 extends out of the mounting frame 120. The scissor lift component 230 is slidably connected to the sliding guide rail 210. The scissor lift component 230 is provided with a lifting element for lifting the roller body 110. The drive component 240 is used to drive the scissor lift component 230 to move up and down, thereby causing the lifting element to move in a direction closer to or away from the roller body 110. The height detection component 220 is used to measure the height of the roller body 110 within the mounting frame 120.

[0047] Please see Figure 1 and Figure 5 The limiting mechanism 300 is detachably connected to the mounting frame 120 and is located between the end of the roller body 110 and the mounting frame 120. The limiting mechanism 300 can abut against the end of the roller body 110.

[0048] Specifically, the mounting frame 120 has an opening on one side, through which the transport mechanism 200 and the limiting mechanism 300 can be inserted into or removed from the mounting frame 120, and the roller 110 can also be inserted into or removed from the mounting frame 120 through the opening. There are two transport mechanisms 200 and two limiting mechanisms 300; one limiting mechanism 300 and one transport mechanism 200 are provided at each opposite end of the roller 110 to limit the movement of the roller 110. The transport mechanism 200 lifts the roller 110 from both ends to achieve lifting stability of the roller 110.

[0049] Please see Figure 1 , Figure 2 , Figure 9, Figure 10 and Figure 11 When a new roller 110 needs to be replaced, the sliding guide rail 210 is first installed in the mounting frame 120, and the scissor lift assembly 230 is moved along the extension direction of the sliding guide rail 210 to directly below the roller 110. Then, the scissor lift assembly 230 is driven to rise by the drive member 240, so that the lifting member moves in a direction close to the roller 110, thereby supporting the roller 110. The limiting mechanism 300 is installed in the mounting frame 120, and the limiting mechanism 300 can abut against the end of the roller 110 to fix the roller 110. Then, the shaft head is removed from the outside of the mounting frame 120 to separate the shaft head from the roller 110. The limiting mechanism 300 can prevent the roller 110 from moving during the removal of the shaft head.

[0050] After the shaft head separates from the roller body 110, the scissor lift assembly 230 is driven to move along the extension direction of the sliding guide rail 210 to the outside of the mounting frame 120, and the height of the roller body 110 supported by the lifting component is detected by the height detection assembly 220. The obtained data is the height of the roller body 110 inside the mounting frame 120.

[0051] After measurement, the roller 110 supported by the lifting component is removed, and a new roller 110 is placed. The height and position of the new roller 110 are adjusted using the height detection component 220 and the scissor lift component 230 so that the height of the new roller 110 is the same as the height of the roller 110 within the mounting frame 120. Then, the scissor lift component 230 is moved along the extension direction of the sliding guide rail 210 into the interior of the mounting frame 120, where the limiting mechanism 300 abuts against the end of the roller 110 to fix it in place. The shaft head can then be installed with the new roller 110. After the shaft head and the new roller 110 are assembled, the transport mechanism 200 and the limiting mechanism 300 can be removed.

[0052] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the scissor lift assembly 230 includes a first scissor arm 231 and a second scissor arm 232, the first scissor arm 231 and the second scissor arm 232 are arranged crosswise, and the first scissor arm 231 and the second scissor arm 232 are hinged at the crosswise position.

[0053] Specifically, the middle portions of the first scissor arm 231 and the second scissor arm 232 are hinged together via a connecting shaft 233. Both the first scissor arm 231 and the second scissor arm 232 have a first end and a second end that are opposite to each other. A pulley 234 is provided at the first end, and the pulley 234 is slidably connected within the sliding guide rail 210. A support roller 235 is provided at the second end, and the support roller 235 can abut against the roller body 110, forming a lifting element. More specifically, the pulley 234 is hinged to the first end of the first scissor arm 231 and the second scissor arm 232. The support roller 235 is hinged to the second end of the first scissor arm 231 and the second scissor arm 232.

[0054] Please see Figure 1 , Figure 2 and Figure 3 The scissor arms 231 and 232 are both two in number, with the two first scissor arms 231 facing each other and spaced apart, and the two second scissor arms 232 facing each other and spaced apart. The two second scissor arms 232 pass between the two first scissor arms 231. The first end of both the two first scissor arms 231 and the two second scissor arms 232 is provided with a pulley 234, which can improve the stability of the movement of the scissor lift assembly 230.

[0055] The support rollers 235, positioned between the two first scissor arms 231 and the two second scissor arms 232, improve the stability of the lifting roller 110. It should be noted that, since the pulleys 234 and support rollers 235 are respectively positioned at both ends of the first scissor arms 231 and the second scissor arms 232, the scissor-type lifting assembly 230 can adaptively move to a suitable position to lift the roller 110.

[0056] An angle is formed between the first scissor arm 231 and the second scissor arm 232. The driving member 240 is used to change the size of the angle, thereby raising and lowering the support roller 235. The driving member 240 can drive the first scissor arm 231 and the second scissor arm 232 to move, thus changing the size of the angle. When the angle increases, the ends of the first scissor arm 231 and the second scissor arm 232 near the support roller 235 move away from each other, and the ends of the first scissor arm 231 and the second scissor arm 232 near the pulley 234 also move away from each other simultaneously, causing the support roller 235 to descend. When the angle decreases, the ends of the first scissor arm 231 and the second scissor arm 232 near the support roller 235 move closer together, and the ends of the first scissor arm 231 and the second scissor arm 232 near the pulley 234 also move closer together simultaneously, causing the support roller 235 to rise.

[0057] Please see Figure 1 , Figure 2 and Figure 3According to some embodiments of this application, optionally, the driving component 240 includes a first adjusting shaft 241, a second adjusting shaft 242, and an adjusting rod 243. The first adjusting shaft 241 is rotatably connected to the first scissor arm 231, and the second adjusting shaft 242 is rotatably connected to the second scissor arm 232. Both the first adjusting shaft 241 and the second adjusting shaft 242 have threaded holes, and the adjusting rod 243 passes through and is threadedly connected to both threaded holes. The two threaded holes on the first adjusting shaft 241 and the second adjusting shaft 242 have opposite rotation directions.

[0058] Specifically, the first adjusting shaft 241 is hinged to the first scissor arm 231 and is located between the support roller 235 and the connecting shaft 233. The second adjusting shaft 242 is hinged to the second scissor arm 232 and is located between the support roller 235 and the connecting shaft 233. The adjusting rod 243 passes through the two first scissor arms 231 and the two second scissor arms 232. For example, the threaded hole of the first adjusting shaft 241 is a right-hand thread. The threaded hole of the second adjusting shaft 242 is a left-hand thread.

[0059] By rotating the adjusting rod 243, the angle can be changed, allowing the end of the first scissor arm 231 near the support roller 235 and the end of the second scissor arm 232 near the support roller 235 to move away from each other or away from each other, thereby enabling the support roller 235 to rise and fall.

[0060] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, a limiting groove 211 is formed on the side wall of the sliding guide rail 210, the extending direction of the limiting groove 211 is parallel to the extending direction of the sliding guide rail 210, and the pulley 234 is slidably disposed in the limiting groove 211. By providing the limiting groove 211, the pulley 234 can be limited to prevent the pulley 234 from shifting or overturning during the forming process.

[0061] Please see Figure 1 , Figure 5 , Figure 12 and Figure 13According to some embodiments of this application, optionally, the limiting mechanism 300 includes a housing 310, a limiting member 320, and a resetting member 330. The housing 310 has a receiving cavity 311 and a through hole 312. The limiting member 320 is accommodated in the receiving cavity 311 and can move axially along the through hole 312 to extend out of the housing 310 and abut against the end of the roller body 110. The resetting member 330 is disposed between the limiting member 320 and the housing 310 to provide a resetting force that tends to keep the limiting member 320 in its initial state. Specifically, the resetting member 330 is a spring. The end of the limiting member 320 away from the through hole 312 is provided with an abutment portion. The resetting member 330 is sleeved on the limiting member 320, and the opposite ends of the limiting member 320 abut against the abutment portion and the housing 310, respectively.

[0062] The limiting member 320 has an initial position and an abutting position. In the initial position, the limiting member 320 is located within the receiving cavity 311 and the through hole 312. In the abutting position, the limiting member 320 extends out of the housing 310. When it is necessary to limit the roller 110, the limiting member 320 can extend out of the housing 310 and abut against the end of the roller 110. When it is not necessary to limit the roller 110, the limiting member 320 can return to the initial position under the action of the reset member 330.

[0063] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 According to some embodiments of this application, optionally, the limiting mechanism 300 further includes a rotating disk 340 and a handle 350 connected to the rotating disk 340. The housing 310 has a rotating groove 313 and a notch 314 formed in the rotating groove 313. The rotating disk 340 is rotatably engaged in the rotating groove 313, and the handle 350 is rotatably provided with the notch 314, and can abut against the two ends of the notch 314 formed by the rotating groove 313. A rotating boss 360 is provided on the side of the rotating disk 340 near the housing 310, abutting against the limiting member 320. The rotating boss 360 is accommodated in the receiving cavity 311. The handle 350 has a first abutting position and a second abutting position. The height of the rotating boss 360 gradually increases in the direction in which the handle 350 rotates from the first abutting position to the second abutting position.

[0064] Specifically, the rotating groove 313 is connected to the receiving cavity 311. The notch 314 formed on the rotating groove 313 is a 90° notch. The handle 350 rotates 90° from the first abutment position to the second abutment position. In the first abutment position, the limiting member 320 abuts against the lowest position of the rotating boss 360. In the second abutment position, the limiting member 320 abuts against the highest position of the rotating boss 360.

[0065] The limiting member 320 has an arc-shaped surface on the side near the rotating boss 360. By providing the arc-shaped surface, the movement of the limiting member 320 on the rotating boss 360 can be facilitated.

[0066] Please see Figure 1 , Figure 5 , Figure 12 and Figure 13 According to some embodiments of this application, optionally, the limiting mechanism 300 further includes a magnetic base 370 and a magnetic element 380, the magnetic element 380 being disposed on the side of the rotating disk 340 away from the housing 310. The magnetic base 370 is connected to the side of the housing 310 near the rotating disk, and when the handle 350 is rotated to the second abutment position, the magnetic base 370 guides the magnetic element 380 to generate a magnetic attraction force.

[0067] Specifically, a receiving groove 341 is provided on the side of the rotating disk 340 away from the housing 310, and the magnetic component 380 is housed in the receiving groove 341. The magnetic base 370 includes a non-magnetic portion 372-371 disposed in the middle and magnetic portions 372 disposed at both ends of the non-magnetic portion 372-371. The two opposite ends of the magnetic component 380 are the N pole and the S pole, respectively. When the handle 350 is rotated to the first abutment position, the extension direction of the magnetic component 380 is parallel to the extension direction of the non-magnetic portion 372-371, and the magnetic base 370 does not act on the magnetic component 380, so the magnetic component 380 cannot generate magnetic attraction. When the handle 350 is rotated to the second abutment position, the extension direction of the magnetic component 380 is perpendicular to the extension direction of the non-magnetic portion 372-371, and the magnetic base 370 acts on the magnetic component 380, causing the magnetic component 380 to generate magnetic attraction, thereby adsorbing it onto the side wall of the mounting bracket 120.

[0068] It should be noted that in the initial state, the handle 350 is in the first abutment position, the limiting member 320 abuts against the lowest position of the rotating boss 360, the limiting member 320 is located in the receiving cavity 311 and the through hole 312, and the magnetic seat 370 does not act on the magnetic member 380. When it is necessary to limit the roller body 110, the limiting mechanism 300 can be placed between the end of the roller body 110 and the mounting frame 120. Then, the handle 350 is rotated from the first abutment position to the second abutment position. The rotating boss 360 can lift the limiting member 320 so that the limiting member 320 extends out of the housing 310 and abuts against the end of the roller body 110. The magnetic seat 370 acts on the magnetic member 380, causing the magnetic member 380 to generate magnetic attraction, so that it can be attracted to the side wall of the mounting frame 120. At the same time, the limiting mechanism 300 can be installed and the roller body 110 can be limited. When it is not necessary to limit the roller body 110, the operable handle 350 can be rotated from the second abutment position to the first abutment position. Under the action of the reset member 330, the limiting member 320 returns to the initial position and the magnetic seat 370 does not act on the magnetic member 380, so that the magnetic member 380 cannot generate magnetic attraction force, thus it can be removed from the mounting bracket 120, and the limiting mechanism 300 can be quickly removed.
