Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulator technology, specifically to a ring die assembly with a protective structure. Background Technology
[0002] A granulator is a device used to aggregate milled solid particles into larger, more easily processed particles. It is widely used in industries such as chemicals, plastics, and animal feed, primarily to process materials into granular or pellet-like forms.
[0003] The ring die assembly is an important component of the granulator. It typically consists of a ring die, a hollow shaft drive disc, and three sets of clamps. The drive disc has the same outer circumference diameter as the ring die. During assembly, the three sets of clamps are evenly divided and the tension of the bolts causes the clamps to hold the drive disc and the ring die tightly together, thus fixing the ring die.
[0004] In existing technology, to remove burrs generated during the machining process of the ring die, a right-angle chamfer is made on the outer circumference of the ring die. However, the edge of the right-angle chamfer is still sharp, which causes the sharp edge to rub against the transmission disc during installation, resulting in wear of the transmission disc. When fixed by clamps, the sharp edge will rub against the clamp jaws, reducing the contact area between the ring die and the clamps, thereby reducing the friction between the ring die and the clamps. Furthermore, due to the complex operating conditions of the granulator, slippage is prone to occur between the ring die and the clamps, accelerating the wear and aging of the clamp jaws, affecting the service life of the clamps, causing the ring die to wobble during use, and leading to a series of mechanical failures.
[0005] Therefore, there is an urgent need to develop a ring die assembly that provides sufficient contact area between the clamp and the ring die, and extends the service life of the clamp. Utility Model Content
[0006] The purpose of this invention is to propose a ring die assembly with a protective structure to solve the problem mentioned in the background art that the outer circumference of the existing ring die has sharp edges, which easily leads to slippage between the ring die and the clamp, affecting the service life of the clamp.
[0007] To achieve the above objectives, this utility model proposes a ring mold assembly with a protective structure, including a transmission disk, a ring mold located at one end of the transmission disk, and a clamping member for connecting the transmission disk and the ring mold. The transmission disk has a groove on its end face facing the ring mold, a first connecting ring is provided on the outer wall of the transmission disk, a convex ring adapted to the groove is provided on the ring mold, and a second connecting ring is provided on the outer wall of the ring mold. The clamping member is installed on the first connecting ring and the second connecting ring.
[0008] Optionally, the second connecting ring and the convex ring are provided with a first protective structure, which includes a first rounded corner and a second rounded corner. The first rounded corner is provided on the end of the convex ring away from the ring mold, and the second rounded corner is provided on the end of the second connecting ring away from the ring mold.
[0009] Optionally, the clamp is composed of multiple arc-shaped clamps connected by bolts, and each arc-shaped clamp is provided with a slot corresponding to the first connecting ring and the second connecting ring, and a rubber strip is installed in the slot.
[0010] Optionally, a first clearance space is formed between the first rounded corner and the groove, and a second clearance space is formed between the second rounded corner and the bayonet.
[0011] Optionally, a second protective structure is provided on the first connecting ring, the second connecting ring, and the clamp.
[0012] Optionally, the second protective structure includes a mounting groove assembly disposed on the first connecting ring and the second connecting ring, a limiting slider mounted in the mounting groove assembly, a connecting groove disposed on the clamp and connected to the mounting groove assembly, a limiting block detachably mounted on the limiting slider and located in the connecting groove, and a mating post mounted on the limiting slider and cooperating with the limiting block.
[0013] Optionally, the mounting slot assembly includes a first mounting slot and a second mounting slot, which are connected to form an L-shaped channel.
[0014] Optionally, both the first connecting ring and the second connecting ring are provided with a first mounting groove and a second mounting groove, and the two first mounting grooves are close to each other and connected; the width of the first mounting groove is equal to the width of the second mounting groove.
[0015] Optionally, the limiting slider includes a second slider located in the second mounting groove and a first slider integrally formed with the second slider. The limiting slider can slide in the mounting groove along the direction of the second slider and is mounted on the second slider with a mating post.
[0016] Optionally, the second mounting groove on the second connecting ring passes through the second connecting ring and communicates with the communicating groove.
[0017] Optionally, one end of the limiting block is provided with a mating hole adapted to the mating post, and a buffer sleeve is installed in the mating hole.
[0018] Optionally, the other end of the limiting block is provided with a disassembly hole.
[0019] Compared with the prior art, the present invention provides a ring mold assembly with a protective structure, which has the following beneficial effects:
[0020] This ring die assembly with a protective structure, through the setting of the first protective structure, changes the original right-angle chamfer on the convex ring and the second connecting ring to a rounded corner, ensuring that no sharp edges are generated after chamfering. This ensures that there will be no rubbing against the transmission plate or clamp during installation, and ensures that the connection contact between the ring die and the transmission plate, and between the ring die and the clamp is a surface contact, reducing the probability of slippage between the ring die and the clamp, reducing the rate of wear and aging of the clamp jaws, and extending the service life of the clamp.

[0035] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0036] The ring die assembly with a protective structure proposed in this application can be applied to applications such as pellet mill ring dies, and of course, it can also be used in other similar application scenarios. The following is a detailed description of a ring die assembly with a protective structure.
[0037] Example 1
[0038] See appendix Figure 1 — Figure 7 The diagram shows a preferred embodiment of a ring mold assembly with a protective structure according to this application. The ring mold assembly with a protective structure includes a transmission disk 1, a ring mold 2 located at one end of the transmission disk 1, and a clamping member 3 for connecting the transmission disk 1 and the ring mold. A groove 11 is provided on the end face of the transmission disk 1 facing the ring mold 2. A first connecting ring 12 is provided on the outer wall of the transmission disk 1. A protruding ring 21 adapted to the groove 11 is provided on the ring mold 2. A second connecting ring 22 is provided on the outer wall of the ring mold 2. The clamping member 3 is mounted on the first connecting ring 12 and the second connecting ring 22. A first protective structure 4 is provided on the second connecting ring 22 and the protruding ring 21.
[0039] This utility model, through the setting of the groove 11 and the cooperation of the convex ring 21, enables the ring mold 2 to be connected and cooperated with the transmission disk 1, increasing the friction between the ring mold 2 and the transmission disk 1; through the setting of the first connecting ring 12 and the second connecting ring 22, an installation position is provided for the clamping part 3, connecting the transmission disk 1 and the ring mold 2.
[0040] The first protective structure 4 includes a first rounded corner 41 and a second rounded corner 42. The first rounded corner 41 is disposed on the end of the convex ring 21 away from the ring mold 2, and the second rounded corner 42 is disposed on the end of the second connecting ring 22 away from the ring mold 2.
[0041] This invention, through the setting of the first rounded corner 41, ensures that when the ring die 2 is engaged with the groove 11 via the engagement of the protruding ring 21 and the groove 11, the end of the protruding ring 21 will not produce a sharp edge, thus ensuring that there is no scraping between the protruding ring 21 and the groove 11 during engagement, ensuring assembly accuracy, and ensuring the contact area between the groove 11 and the protruding ring 21, thus guaranteeing the friction between the protruding ring 21 and the groove 11. Through the setting of the second rounded corner 42, when the clamping member 3 is installed on the first connecting ring 12 and the second connecting ring 22, the end of the second connecting ring 22 will not produce a sharp edge, ensuring that the contact between the second connecting ring 22 and the clamping member 3 is a surface contact, guaranteeing the friction between the second connecting ring 22 and the clamping member 3, preventing slippage between the clamping member 3 and the second connecting ring 22 due to sharp edges, reducing the wear and aging rate of the clamping member, and extending the service life of the clamping member 3.
[0042] See appendix Figure 5 — Figure 7 As shown, in this utility model, each arc-shaped clamp is provided with a slot 31 corresponding to the first connecting ring 12 and the second connecting ring 22, and a rubber strip 32 is installed in the slot 31.
[0043] This utility model uses the rubber strip 32 to increase the friction between the inner wall of the bayonet 31 and the first connecting ring 12 and the second connecting ring 22, thereby enhancing the stability of the connection and further preventing slippage during high-speed rotation. In addition, the rubber strip 32 can absorb some vibration and impact, reduce the direct friction between the clamp 3 and the ring mold 2 and the transmission disc 1, and extend the service life of each component.
[0044] See appendix Figure 5 and Figure 6 As shown, in this utility model, a first clearance space 43 is formed between the first rounded corner 41 and the groove 11, and a second clearance space 44 is formed between the second rounded corner 42 and the bayonet 31.
[0045] By providing a first clearance space 43 and a second clearance space 44, this utility model ensures that when the convex ring 21 is connected to the groove 11 and the second connecting ring 22 is connected to the clamp 3, the edges will not come into contact, thus avoiding contact and friction of the sharp areas of the edges, which would affect the overall contact and friction surface.
[0046] Example 2
[0047] See appendix Figure 8 — Figure 13As shown, in this utility model, a second protective structure 5 is provided on the first connecting ring 12, the second connecting ring 22, and the clamp 3. The second protective structure 5 includes a mounting groove group 51 provided on the first connecting ring 12 and the second connecting ring 22, a limiting slider 52 installed in the mounting groove group 51, a connecting groove 53 provided on the clamp 3 and connected to the mounting groove group 51, a limiting block 54 detachably installed on the limiting slider 52 and located in the connecting groove 53, and a mating post 55 installed on the limiting slider 52 and cooperating with the limiting block 54.
[0048] This utility model provides an installation position for the limiting slider 52 by setting the mounting groove group 51; and provides an installation position for the limiting block 54 by setting the connecting groove 53, and provides conditions for the connection between the limiting block 54 and the mating column 55.
[0049] See appendix Figure 8 — Figure 11 As shown, in this utility model, the mounting groove group 51 includes a first mounting groove 511 and a second mounting groove 512, which are connected to form an L-shaped channel; the first connecting ring 12 and the second connecting ring 22 are each provided with a first mounting groove 511 and a second mounting groove 512, and the two first mounting grooves 511 are close to each other and connected; the groove width of the first mounting groove 511 is equal to the groove width of the second mounting groove 512.
[0050] This utility model, through the setting of the first mounting groove 511 and the second mounting groove 512, ensures that there will be no slippage between the transmission disc 1 and the ring mold 2. It should be noted that the distance between the parallel groove surfaces of the first mounting groove 511 on the first connecting ring 12 and the first mounting groove 511 on the second connecting ring 22 is equal to the longest distance of the limiting slider 52, ensuring that the limiting slider 52 can enter the second mounting groove 512 through the first mounting groove 511, thereby ensuring that after the limiting slider 52 is installed, it will not slide out of the mounting groove group 51 at will.
[0051] See appendix Figure 11 — Figure 13 As shown, in this utility model, the limiting slider 52 includes a second slider 522 located in the second mounting groove 512 and a first slider 521 integrally formed with the second slider 522. The limiting slider 52 can slide in the mounting groove group 51 along the direction of the second slider 522. The length of the first slider 521 is less than the length of the second slider 522. The mating post 55 is mounted on the second slider 522. The second mounting groove 512 on the second connecting ring 22 passes through the second connecting ring 22 and is connected to the communicating groove 53.
[0052] This utility model, through the setting of the first slider 521 and the second slider 522, which correspond to the first mounting groove 511 and the second mounting groove 512, can effectively prevent slippage between the ring mold 2 and the transmission disk 1; by connecting the second mounting groove 512 and the connecting groove 53, the limiting block 54 can cooperate with the mating column 55 to prevent the clamping part 3 from slipping with the ring mold 2 or the transmission disk 1.
[0053] See appendix Figure 11 As shown, in this utility model, one end of the limiting block 54 is provided with a mating hole 541 that is adapted to the mating post 55, and a buffer sleeve 542 is installed in the mating hole 541.
[0054] This utility model uses the mating hole 541 to cooperate with the mating post 55 to limit the clamping part 3 and prevent the clamping part 3 from slipping with the ring mold 2; the buffer sleeve 542 avoids hard friction between the mating hole 541 and the mating post 55, so that the limiting block 54 and the mating post 55 can be frequently disassembled and assembled.
[0055] See appendix Figure 11 and Figure 12 As shown, in this utility model, the other end of the limiting block 54 is provided with a disassembly hole 543; the setting of the disassembly hole 543 makes it convenient for workers to disassemble the limiting block 54.
[0056] See appendix Figure 8 — Figure 13 As shown, the steps for mounting the ring mold 2 on the transmission disc 1 according to this utility model are as follows:
[0057] The first step is to lift the ring mold 2 using an electric hoist so that the protruding ring 21 on the ring mold 2 is aligned with the groove 11 on the transmission disc 1 and inserted.
[0058] The second step is to maintain the height of the electric hoist and adjust the position of the mounting slot group 51 of the ring mold 2 by rotating the ring mold 2 so that the mounting slot group 51 on the ring mold 2 corresponds to and connects with the mounting slot group 51 on the transmission plate 1.
[0059] The third step is to install the limiting slider 52 in the mounting slot group 51. Specifically, the second slider 522 on the limiting slider 52 is aligned with the first mounting slot 511 and inserted, so that the second slider 522 passes through the first mounting slot 511 and enters the second mounting slot 512. Then, the limiting slider 52 is moved along the direction of the second mounting slot 512 to prevent the limiting slider 52 from falling out.
[0060] The fourth step is to fix the mating post 55 onto the second slider 522 through the second mounting groove 512 of the second connecting ring 22;
[0061] Fifth step: clamp the first connecting ring 12 and the second connecting ring 22 with the arc-shaped clamp, and connect the connecting groove 53 with the second mounting groove 512 of the second connecting ring 22.
[0062] Step 6: Insert the limiting block 54 into the connecting groove 53 so that the mating hole 541 mates with the mating post 55.
[0063] Step 7: After all the arc-shaped clamps have been installed in steps 5 and 6, connect the adjacent arc-shaped clamps with bolts to form clamp component 3.
[0064] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
