Description

Technical Field

[0001] This invention belongs to the technical field of pellet mill equipment, specifically relating to an automatic ring die assembly and disassembly device. Background Technology

[0002] Traditional ring die hoisting assemblies are manually operated mechanical structures. Each time a customer needs to replace a ring die, the hoisting assembly is first bolted to the die to secure it. Next, the rollers in the hoisting assembly are connected to the winch's cable to further secure the hoisting structure. Then, a person manually pushes the die out from the rear of the pellet mill and uses the winch to lower it to the ground for disassembly. During installation, the hoisting assembly is bolted to the die, and the winch lifts it to the installation location. This requires constant manual alignment to secure the die, and the hoisting assembly and disassembly are achieved by raising and lowering the cable. This requires frequent manual operation, and the heavy weight of the hoisting structure makes manual operation difficult, resulting in a poor customer experience. This method of ring die assembly and disassembly is cumbersome, entirely manual, and labor-intensive, causing significant inconvenience and low production efficiency. Furthermore, the winch cable is susceptible to corrosion from prolonged exposure to steam, posing a safety hazard due to the risk of breakage over time. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic ring mold assembly and disassembly device to solve the technical problems of existing ring mold disassembly methods that use hoisting components, which are cumbersome, involve high manual labor intensity, and pose safety hazards.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic ring die assembly and disassembly device, comprising:

[0005] Fuselage structure;

[0006] A lifting mechanism, mounted on the machine body, is used to drive the ring mold to move vertically.

[0007] A ring mold support mechanism is mounted on the lifting mechanism to support and position the ring mold.

[0008] A ring mold assembly / disassembly mechanism is mounted on the lifting mechanism and located above the ring mold support mechanism. The ring mold assembly / disassembly mechanism is used to connect with the ring mold and drive the ring mold to move along the axial direction of the ring mold, thereby realizing the disassembly and installation of the ring mold.

[0009] This invention's automatic ring die assembly / disassembly mechanism consists of four parts: a machine body, a lifting mechanism, a ring die support mechanism, and a ring die assembly / disassembly mechanism. The lifting mechanism enables reciprocating motion in the vertical direction, ensuring the ring die can be placed on the ground after being released and facilitating its installation. The ring die assembly / disassembly mechanism removes the ring die from the equipment or enables automatic replacement. This invention's ring die assembly / disassembly mechanism is primarily used for the rapid replacement of ring dies in pellet mills. No manual operation is required during ring die replacement; electric components facilitate assembly and disassembly, reducing labor intensity, enhancing equipment automation and production efficiency, and improving the customer's equipment experience. It allows for automatic ring die assembly / disassembly without manual intervention. This invention enables automatic ring die replacement, significantly reducing replacement time, increasing production efficiency, reducing manual labor intensity, and improving equipment safety.

[0010] This invention's ring die assembly / disassembly device eliminates the need for assembly / disassembly tools, solving the problems of heavy weight and inconvenient manual operation associated with previous ring die assembly / disassembly devices. As a movable device, this ring die assembly / disassembly device avoids contact with steam, preventing corrosion and improving operational safety.

[0011] To address the technical problem of heavy lifting structures that are difficult to operate manually, the present invention adopts the following technical solution: the lifting mechanism includes a first power component and a sliding component; the first power component is mounted on the body mechanism, and the first power component drives the sliding component to move in the vertical direction.

[0012] The lifting mechanism of this invention uses a first power component for transmission, which realizes the reciprocating motion of the structure in the vertical direction, ensuring that the ring mold can be placed on the ground after being released, and facilitating the installation of the ring mold. This invention facilitates the disassembly and assembly of the ring mold by using the first power component, reducing manual labor intensity and enhancing the automation and production efficiency of the equipment.

[0013] To solve the technical problem of inconsistent vertical reciprocating motion of the mechanism, the present invention adopts the following technical solution: a first guide frame is provided on the body mechanism to guide the sliding component. The first guide frame ensures the consistency of vertical motion, which is simple in structure, low in cost and has good stability.

[0014] To solve the technical problem of how to realize the first power component, the present invention adopts the following technical solution, wherein the first power component is a hydraulic cylinder;

[0015] The sliding assembly includes a U-shaped sliding frame and a first roller mounted on the sliding frame.

[0016] The lifting mechanism of this invention uses hydraulic cylinder transmission, and the reciprocating motion of the structure in the vertical direction is realized by the extension and retraction of the hydraulic cylinder, which ensures that the ring mold can be placed on the ground after being released and facilitates the installation of the ring mold; the sliding component of this invention adopts a U-shaped structure, which is simple in structure, low in cost and has good stability.

[0017] To address the technical problem of how to implement a ring mold support mechanism, this invention adopts the following technical solution: the ring mold support mechanism includes a support rod and a rotating support member disposed at the end of the support rod, the support rod being mounted on the sliding assembly. This invention utilizes the support rod and the support member to effectively support the ring mold.

[0018] To address the technical problem of how to implement a rotating support component, this invention adopts the following technical solution: the rotating support component includes a first rotating support component and a second rotating support component arranged in parallel, with the central axis of the first rotating support component perpendicular to the support rod; the first rotating support component and the second rotating support component are sliding bearings or rotating rollers. This invention utilizes sliding bearings or rotating rollers as rotating support components, resulting in a simple structure, low cost, and stable support.

[0019] To address the technical problem of how to implement the ring die assembly / disassembly mechanism, the present invention adopts the following technical solution: the ring die assembly / disassembly mechanism includes a second power component and a moving component; the second power component is mounted on the sliding component via a mounting bracket; the second power component drives the moving component to move in the horizontal direction.

[0020] A connecting plate is provided on the movable component, and the connecting plate is used to connect the ring mold;

[0021] A second guide mechanism is provided between the movable component and the mounting bracket.

[0022] The ring die assembly / disassembly mechanism of this invention uses a second power component for transmission. The second power component enables reciprocating motion of the structure in the horizontal direction. The operation and reset of the second power component are controlled. When the second power component is working, it disassembles the ring die from the equipment. When the second power component is reset, it installs the new ring die, realizing automatic replacement of the ring die. This invention facilitates the assembly / disassembly of the ring die using a second power component, reduces manual labor, and enhances the automation and production efficiency of the equipment.

[0023] To address the technical problem of inconsistent horizontal reciprocating motion of the mechanism, this invention employs the following technical solution: a second guide frame is provided on the mounting frame to guide the horizontal movement of the moving component. This invention utilizes the second guide mechanism to ensure consistent horizontal movement, resulting in a simple structure, low cost, and good stability.

[0024] To address the technical problem of how to realize the second power component, the moving component, and the mounting bracket, the present invention adopts the following technical solution, wherein the second power component is a cylinder;

[0025] The moving component is a U-shaped frame and a traction frame mounted on the U-shaped frame, the traction frame being connected to the output end of the second power component; a second roller is mounted on the U-shaped frame;

[0026] The mounting bracket has an H-shaped structure.

[0027] The ring mold assembly / disassembly mechanism of this invention uses a cylinder as a power source, and a steering valve controls the operation and reset of the cylinder. When the cylinder is working, the ring mold is disassembled from the equipment under the action of the cylinder force; when the cylinder resets, a new ring mold is installed in place, realizing automatic ring mold replacement. The moving component of this invention uses a U-shaped frame, a traction frame, and connects to the output end of the second power component, resulting in a simple structure, low cost, convenient installation, and good stability. The mounting frame of this invention uses an H-shape, which is also simple in structure, low in cost, convenient to install, and has good stability.

[0028] To address the technical problem of displacement of the entire device during ring die replacement, this invention employs the following technical solution: a caster wheel is installed on the machine body, and locking components are mounted on the caster wheel. The bottom of the machine body is equipped with a self-locking caster wheel. The caster wheel enhances the ease of movement of the device, and when its self-locking function is activated, the entire device is fixed in place, preventing displacement during ring die replacement.

[0059] like Figure 1-19 As shown, the automatic ring die assembly and disassembly device 10 includes a machine body mechanism 100, a lifting mechanism 200, a ring die support mechanism 300, and a ring die assembly and disassembly mechanism 400.

[0060] The fuselage mechanism 100 includes a handle 101, a first bracket 102, a second bracket 103, and a third bracket 104. The first bracket 102 is welded to the second bracket 103, and the second bracket 104 is welded to the second bracket 103 on both sides.

[0061] In one embodiment, the fuselage mechanism 100 further includes a first guide frame, comprising a reinforcing rib 105, a first fixing plate 106, and a second fixing plate 107. The first fixing plate 106 is welded to the first bracket 102, the reinforcing rib 105 is welded to the bottom of the first fixing plate 106 to increase strength, and the second fixing plate 107 is welded to the first bracket 102 and the first fixing plate 106.

[0062] In one embodiment, the body mechanism 100 further includes a connecting plate 108 and a drive wheel 109. The connecting plate 108 is welded to the bottom of the bracket 103, and the drive wheel 109 is bolted to the connecting plate 108. The drive wheel 109 is a universal wheel with a self-locking function, which improves the flexibility of the device.

[0063] In one embodiment, a handle 101 is welded onto the bracket 102, and the operator moves the ring mold automatic disassembly and assembly device 10 by means of the handle 101.

[0064] The lifting mechanism 200 includes a sliding assembly 210, a first power component 220, and a support plate 230. The sliding assembly 210 has a U-shaped structure and includes a retaining ring 211, a pin 212, a connecting plate 213, a top sleeve 214, and a sliding bearing 215. The connecting plate 213 has holes on both sides, through which the pin 212 passes and is welded to secure it. The top sleeve 214 passes through the pin 212, with one end fitting against the connecting plate 213 and the other end fitting against the sliding bearing 215. The outer side of the pin 212 has a groove for mounting with the retaining ring 211, and the outer side of the sliding bearing 215 fits against the retaining ring 211 for fixation. A threaded hole is located in the middle of the connecting plate 213 for mounting with the external thread of the output shaft of the first power component 220, thus securing the first power component 220. A first guide frame guides the sliding bearing 215 of the sliding assembly 210.

[0065] The first power component 220 is preferably a hydraulic cylinder. The first power component 220 in the lifting mechanism 200 is welded to the bracket 104 in the body mechanism 100 to fix the first power component 220 (hydraulic cylinder). The sliding bearing 215 is installed on the surface of the fixed plate 106. When the first power component 220 works, the sliding bearing 215 slides up and down on the surface of the bracket 102 to achieve vertical movement.

[0066] The ring mold support mechanism 300 includes a support plate 304 and a rotating support member at the end of the support plate 304. There are two support plates 304. The support plates 304 of the ring mold support mechanism 300 are welded and fixed to the connecting plate 213 in the lifting mechanism 200, which serves to support the ring mold during replacement.

[0067] In one embodiment, the rotating support includes a retaining ring 301, a top sleeve 302, a sliding bearing 303, a pin 305, and a second support plate 306. The front end of the first support plate 304 is welded to the second support plate 306. The second support plate 306 has an opening at its end. The pin 305 passes through the opening and is welded to the second support plate 306. The top sleeve 302 passes through the pin 305, with one end fitting against the second support plate 306 and the other end fitting against the sliding bearing 303. The outer side of the pin 305 has a groove for mounting with the retaining ring 301. The outer side of the sliding bearing 303 fits against the retaining ring 301 for fixation. The spacing of the sliding bearings 303 should be consistent with the ring die specifications.

[0068] In one embodiment, the rotating support can also be a rotating roller.

[0069] The ring mold assembly and disassembly mechanism 4 includes a fixing device 410, a bolt assembly 420, a moving assembly 430, and a power assembly 440.

[0070] The fixing device 410 is H-shaped and includes a first fixing plate 411, a second fixing plate 412, a connecting plate 413, and a fixing plate 414. The two ends of the connecting plate 413 are welded to the fixing plate 414. In one embodiment, the first fixing plate 411 and the second fixing plate 412 are welded to the fixing plate 414 to form a second guide frame.

[0071] The moving component 430 mainly consists of a sliding component 211, a moving plate 432, a traction frame 433, a reinforcing rib 434, and a connecting plate 435. The moving plate 432 is welded and fixed to the connecting plate in the sliding component 211. The reinforcing rib 434 is welded to the moving plate 432 and the connecting plate 213 respectively to strengthen the structural strength. The traction frame 433 is welded to the moving plate 432. The traction frame 433 has an opening in the middle part. After welding, it coincides with the center of the moving plate 432. The connecting plate 435 is welded above the connecting plate 213 in the sliding component 210.

[0072] The power assembly 440 mainly consists of a fixed plate 441, a valve seat 442, a reinforcing rib 443, a working valve 444, a second power component 445, and a connecting sleeve 446. The second power component 445 is preferably a cylinder. The fixed plate 441 has mounting holes machined in it and is fixedly connected to the second power component 445 and the valve seat 442 by bolts. The reinforcing rib 443 is welded to the fixed plate 441 to increase strength. The valve seat 442 has mounting holes machined in it and is fixedly connected to the working valve 444 by bolts. The connecting sleeve 446 has external threads machined on its outer side and internal threads machined on its inner side, and is connected to the second power component 445 via the internal threads.

[0073] In the ring mold assembly and disassembly mechanism 400, the connecting sleeve 446 passes through the traction frame 433 and is fixed by the bolt assembly 420. The fixing plate 441 and the reinforcing rib 443 are welded and fixed to the connecting plate 413. After welding, the sliding bearing in the sliding assembly 413 is placed on the upper surface of the fixing plate 431 in the fixing device 410. When the second power component 445 (cylinder) is working, the sliding bearing 215 can move horizontally. During the movement, the fixing plate 1 411 and the fixing plate 2 412 play an auxiliary limiting role for the sliding bearing 445.

[0074] The ring mold assembly and disassembly mechanism 400 is welded and fixed to the connecting plate 213 of the sliding component 210 in the lifting mechanism 200 via the fixing plate 414 in the fixing device 410, thus realizing the structure of the entire device.

[0075] As the core component of the pellet mill 500, the ring die 501 is designed with tapered structures at both ends, and the tapered dimensions of the left and right ends are consistent. The inner side of the transmission wheel rim 502 is machined with a tapered shape to match the tapered shape of the ring die 501. The two are interference fit, which ensures that they will not loosen after installation.

[0076] How to use the automatic ring die assembly / disassembly device 10:

[0077] When disassembling the ring die 501, the operator pushes the automatic ring die disassembly and assembly device to the front of the pellet mill 500 through the handle 101, and then activates the self-locking device in the drive wheel 109 to fix the entire device and prevent the device from moving during operation.

[0078] After the device is fixed, the first power component 220 (hydraulic cylinder) starts to work. When the hydraulic cylinder extends, the sliding bearing 215 in the sliding assembly 210 moves upward. During the movement, the fixing plate 107 in the machine body mechanism 100 plays a limiting role to prevent the sliding bearing 215 from deviating from its movement trajectory. When the sliding bearings 215 at both ends in the ring die support mechanism 300 are tangent to the surface of the ring die 501, the first power component 220 (hydraulic cylinder) stops working. During the upward movement of the device, the second power component 445 (cylinder) in the ring die disassembly and assembly mechanism 400 needs to be kept moving in the center direction of the granulator 500. When the device moves into place, the connecting plate 435 is fixed to the ring die 501 by bolts 503, thus fixing the entire device to the granulator.

[0079] Rotate the working valve 444, the second power component 445 (cylinder) works, the second power component 445 (cylinder) extends, when the applied cylinder force is greater than the connection force between the ring die 501 and the transmission wheel rim 502, the ring die 501 separates from the transmission wheel rim 502, then unlock the drive wheel 109, move the device outward, and move the ring die 501 away from the pellet mill 500. Then the first power component 220 (hydraulic cylinder) works, retracts its stroke, and the device moves downward. When the ring die 501 moves to the ground, the first power component 220 (hydraulic cylinder) stops working, loosens the bolt 503, and removes the ring die.

[0080] When installing a new ring die 501, first place the ring die 501 on the surface of the sliding bearing 215 in the ring die support mechanism 300. Use bolts 503 to connect the connecting plate 435 in the ring die assembly / disassembly mechanism 400 to the ring die 501. The first power component 220 (hydraulic cylinder) starts working and lifts the device to the point where the center of the ring die 501 coincides with the transmission wheel rim 502. Then the first power component 220 (hydraulic cylinder) stops working. Then the second power component 445 (cylinder) in the ring die assembly / disassembly mechanism 400 works, the stroke retracts, and the ring die 501 is placed at the installation location and installed in conjunction with the ring die wheel rim 502 to fix the ring die 501.

[0081] The ring die assembly and disassembly mechanism of this invention can realize the automatic assembly and disassembly of ring dies without manual operation, thereby reducing manual labor and greatly improving production efficiency and operational safety.
