Description

Technical Field

[0001] This utility model relates to the field of rubber product conveying technology, and in particular to a centrifugal disc feeder that is easy to clean. Background Technology

[0002] Centrifugal disc feeders are used in the production of rubber products. A centrifugal disc feeder is a device that uses centrifugal force to transport rubber products from a feeding device to a conveying device. A centrifugal disc feeder typically consists of an inclined centrifugal disc and a horizontal disc. The inclined centrifugal disc throws the rubber products onto the edge disc, which then arranges the rubber products neatly and transports them out. Because the central axes of the centrifugal disc and the disc are not aligned, gaps inevitably exist between the inclined centrifugal disc and the disc. Dust or liquid adhering to the rubber products can easily seep into the equipment through these gaps, potentially damaging the equipment over time. Furthermore, the inclined shape of the centrifugal disc makes disassembly and assembly cumbersome, and each cleaning operation is extremely time-consuming. Therefore, there is a need for a centrifugal disc feeder that is easier to clean. Utility Model Content

[0039] The present invention will be described in detail below with reference to specific embodiments.

[0040] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0041] like Figures 1 to 16As shown, this utility model provides a centrifugal disc feeder that is easy to clean, including a frame 1, a protective cover 2 on the frame 1, a turntable 3 inside the protective cover 2, and a bearing between the turntable 3 and the protective cover 2; a centrifugal assembly 4 is provided on the turntable 3, the centrifugal assembly 4 includes a disc 41, a centrifugal disc 40, a main rotating shaft 42, a swing frame 43, a main shaft drive 44, and a swing frame drive 45. The main rotating shaft 42 is obliquely mounted in the turntable 3 through a joint bearing 30, the centrifugal disc 40 is mounted on the main rotating shaft 42, the disc 41 is mounted in the turntable 3, and the disc 41 is located outside the centrifugal disc 40; the swing frame 43 is located at the bottom of the main rotating shaft 42 and can slide on the frame 1; the swing frame drive 45 is mounted on the frame 1 and is used to drive the swing frame 43 to slide on the frame 1; the main shaft drive 44 is mounted on the swing frame 43 and is used to drive the main rotating shaft 42 to rotate.

[0042] In this embodiment, a rotary drive 46 is provided on the frame 1, which is used to drive the turntable 3 to rotate.

[0043] Through the above design scheme, the bearing can reduce the friction between the turntable 3 and the protective cover 2, so that the rotary drive 46 can drive the turntable 3 to rotate in the protective cover 2. The disc 41 installed on the turntable 3 can generate centrifugal force to throw the rubber product to the edge of the turntable 3, allowing the rubber product to move along the protective cover 2. When the material is being loaded, the workers or the loading equipment pour the rubber product into the centrifugal disc 40. The main shaft drive 44 drives the centrifugal disc 40 to rotate through the main rotating shaft 42. The tilted centrifugal disc 40 can throw the rubber product to the edge, and then enter the disc 41 along the tilt direction of the centrifugal disc 40. The disc 41 sorts and discharges the rubber product. The swing frame 43 at the bottom of the main rotating shaft 42 can control the tilt angle of the main rotating shaft 42. The tilted centrifugal disc 40 can facilitate the rubber product to enter the disc 41 from the centrifugal disc 40. Although the tilted centrifugal disc 40 can feed materials, its tilted shape makes it extremely inconvenient to disassemble and assemble. With the above design, when disassembly is required, the swing frame drive 45 can drive the main rotating shaft 42 to swing, so that the central axis of the main rotating shaft 42 coincides with the central axis of the turntable 3 and the protective cover 2. In this state, the centrifugal disc 40 will change from tilted to parallel, making it easier for workers to disassemble and assemble.

[0044] In this embodiment, the inner surface of the disk 41 is an arc surface 410, the center of the arc surface 410 coincides with the center of the spherical bearing 30, and the arc surface 410 is in contact with the centrifugal disk 40; a limiting post 411 is provided on the outer side of the disk 41, and a limiting groove 31 corresponding to the limiting post 411 is provided in the turntable 3, and the limiting groove 31 fits with the limiting post 411.

[0045] Through the above design scheme, the arc surface 410 on the disc 41 can make the centrifugal disc 40 fit against the disc 41, reducing the gap between the two, thereby reducing the seepage of dust or liquid from the rubber product into the turntable 3 through the gap between the centrifugal disc 40 and the disc 41; since the center of the arc surface 410 coincides with the center of the spherical bearing 30, the arc surface 410 will have a shape that is smaller at the top and larger at the bottom. When it is necessary to remove the disc 41, the arc surface 410 with a smaller top and larger bottom can make it easier for the staff to remove the disc 41 by hand.

[0046] The limiting groove 31 on the turntable 3 can lock the limiting post 411, so that the disc 41 can rotate synchronously with the turntable 3, and avoid the disc 41 from sliding between the disc and the turntable 3, which would affect the feeding efficiency.

[0047] In this embodiment, a protrusion 400 is provided at the center of the centrifuge disc 40, and a mounting hole 401 is provided in the protrusion 400. A T-shaped groove 402 is provided on the inner wall of the mounting hole 401. The T-shaped groove 402 includes a through section 406, an annular section 407 and a locking section 408. The annular section 407 is located deep in the mounting hole 401 and is parallel to the centrifuge disc 40. The through section 406 is parallel to the locking section 408 and both the through section 406 and the locking section 408 are connected to the annular section 407. A locking block 420 is provided on the main rotating shaft 42. The locking block 420 can enter the annular section 407 and the locking section 408 sequentially through the through section 406. A quick-release elastic element 421 is installed inside the main rotating shaft 42 at the position corresponding to the locking block 420.

[0048] In this embodiment, a gripping part 405 is provided on the protrusion 400.

[0049] Because the centrifugal force on the rubber product at the center of the centrifugal disc 40 is relatively small, if the rubber product has a special shape, it may fall and remain at the center of the centrifugal disc 40, affecting processing efficiency. Through the above design, the protrusion 400 on the centrifugal disc 40 can prevent the rubber product from getting stuck at the center of the centrifugal disc 40, allowing the rubber product to smoothly slide along the centrifugal disc 40 from the center to the edge of the centrifugal disc 40.

[0050] During the processing of rubber products, dust or cleaning fluid, or raw material debris may remain on their surface. These impurities or solutions will seep into the equipment through the gap between the centrifugal disc 40 and the disc 41 and enter the rotating disc 3. Over time, many impurities will accumulate in the rotating disc 3, and excessive impurities will affect the working efficiency of the centrifugal disc 40.

[0051] With the above design, when the centrifugal disc 40 needs to be removed for cleaning, the swing frame drive 45 controls the swing frame 43 to drive the main rotating shaft 42 back to center. The operator can first lift the disc 41 upwards to remove it from the protective cover 2. Then, the operator can grasp the gripping part 405 on the protrusion 400 and press the protrusion 400 downwards to make the locking block 420 on the main rotating shaft 42 slide out of the locking section 408 and into the annular section 407. Then, rotate the protrusion 400 to make the locking block 420 slide in the annular section 407. Since the height of the annular section 407 is different from that of the locking block 420, the locking block 420 will slide in the annular section 407. When the heights are close, the locking block 420 can rotate normally during the annular section 407. When the locking block 420 rotates to align with the through section 406, the centrifugal disc 40 automatically pops up under the action of the quick-release elastic element 421, the locking block 420 slides out of the through section 406, the centrifugal disc 40 disengages from the main rotating shaft 42, and the operator can directly remove the centrifugal disc 40, exposing the turntable 3, which is convenient for the operator to clean the turntable 3 and the protective cover 2. The disassembled centrifugal disc 40 and disc 41 can be completely immersed in the cleaning solution for cleaning, ensuring that the centrifugal disc 40 and disc 41 are clean. When assembly is required, the operator can hold the grip 405, align the through section 406 with the locking block 420, press the protrusion 400 to rotate the locking block 420 along the through section 406 into the annular section 407, and then rotate the protrusion 400 to slide the locking block 420 in the annular section 407; when the locking block 420 reaches the locking section 408, the centrifugal disc 40 springs up under the action of the quick-release elastic element 421, so that the locking block 420 is locked into the locking section 408, ensuring that the centrifugal disc 40 can rotate together with the main rotating shaft 42.

[0052] In this embodiment, a support platform 20 is provided on the protective cover 2, and a ball bearing 21 is provided on the support platform 20. The ball bearing 21 is used to support the rotation of the disc 41.

[0053] Through the above design scheme, the ball bearings 21 on the support platform 20 can reduce the friction between the cover 2 and the disc 41, and prevent the rotating disc 41 from rubbing against the cover 2 and causing wear. At the same time, the ball bearings 21 can also provide support for the disc 41, and prevent the rubber products on the disc 41 from being too heavy and affecting the balance.

[0054] In this embodiment, a sealing groove 403 is provided on the edge of the centrifugal disc 40, and a rotating sealing ring 404 is installed in the sealing groove 403.

[0055] Through the above design scheme, the rotating sealing ring 404 in the edge sealing groove 403 of the centrifugal disc 40 can further improve the sealing performance between the centrifugal disc 40 and the disc 41, and further reduce the infiltration of impurities. After long-term operation, the impurities in the gap will increase. Excessive impurities will cause friction between the disc 41 and the centrifugal disc 40, reducing the service life of the disc 41 and the centrifugal disc 40. Therefore, after the rotating sealing ring 404 and the centrifugal disc 40 are disassembled, the operator can disassemble the rotating sealing ring 404 for cleaning to ensure the cleanliness of the equipment.

[0056] In this embodiment, the protective cover 2 is provided with a discharge port 6, and a fastening slide rail 60 is provided at the discharge port 6. The fastening slide rail 60 is used to install the discharge plate 7. The bottom of the discharge plate 7 is provided with a fastening groove 70, and an opening 71 is provided on one side of the fastening groove 70.

[0057] Through the above design, the discharge port 6 on the protective cover 2 can guide the rubber products away from the disc 41 from the discharge port 6. The discharge plate 7 at the discharge port 6 can intercept the rubber products on the disc 41 and sort the rubber products to the discharge port 6. At the same time, the discharge plate 7 can also hold the disc 41 in place, preventing the disc 41 from rising and detaching from the centrifugal disc 40 during processing. When it is necessary to remove the discharge plate 7, the user can push the discharge plate 7 to slide the fastening slide rail 60 from the depth of the fastening groove 70 to the opening 71, and then lift the discharge plate 7 upwards to remove it. When it is necessary to install the discharge plate 7, the operator can align the opening 71 with the fastening slide rail 60, and after the fastening slide rail 60 enters the fastening groove 70, pull the discharge plate 7 back to make the fastening slide rail 60 lock into the depth of the fastening groove 70.

[0058] In this embodiment, a discharge conveyor belt 5 is provided at the discharge port 6. The discharge conveyor belt 5 can be connected to a packaging box or the next set of processing equipment to transport the neatly arranged rubber products out.

[0059] In this embodiment, a limiting slider 430 is provided on the swing frame 43, and an arc-shaped slide groove 10 is provided on the frame 1, so that the limiting slider 430 can slide in the arc-shaped slide groove 10.

[0060] Through the above design scheme, the limiting slider 430 and the arc-shaped slide 10 can limit the swing range of the swing frame 43. When the swing frame drive 45 pulls the swing frame 43 back, the limiting slider 430 slides to the front end of the arc-shaped slide 10. At this time, the central axis of the main rotating shaft 42 coincides with the central axis of the turntable 3. At this time, the centrifugal disc 40 is in a horizontal state. The horizontal centrifugal disc 40 can be more easily disassembled and installed. When the swing frame drive 45 extends, the swing frame 43 is pushed to the other end, and the limiting slider 430 slides to the end of the arc-shaped slide 10. At this time, the central axis of the main rotating shaft 42 intersects with the central axis of the turntable 3, and the included angle between the two is 5 degrees, ensuring that the centrifugal disc 40 is in an inclined state to facilitate feeding.

[0061] In this embodiment, the swing frame drive 45 is preferably a hydraulic cylinder or a pneumatic cylinder, and the main shaft drive 44 and the rotary drive 46 are preferably motors.

[0062] The centrifugal disc feeder provided by this utility model is easy to clean. Compared with the prior art, the swing frame drive component 45 extends, causing the swing frame to tilt with the main rotating shaft 42, which facilitates the feeding operation. When the centrifugal disc 40 needs to be disassembled for cleaning, the swing frame drive component 45 can pull the swing frame back so that the main rotating shaft 42 coincides with the central axis of the disc 41, which facilitates disassembly and assembly. During disassembly and assembly, the operator can hold the centrifugal disc 40 through the grip part 405, press down on the centrifugal disc 40 to make the locking block 420 enter the annular section 407 from the locking section 408, and then rotate the centrifugal disc 40 to make the locking block 420 slide to the through section 406. Under the action of the quick-release elastic component 421, the centrifugal disc 40 will be popped up, which makes it convenient for the user to remove the disc 41 and the centrifugal disc 40, so that the operator can clean the disc 41, the centrifugal disc 40 and the turntable 3.

[0063] Where there is no conflict, the above embodiments and features can be combined with each other.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
