Description

Technical Field

[0001] This utility model belongs to the field of hard capsule production technology, and mainly relates to an automatic felt filling machine. Background Technology

[0002] In the capsule manufacturing process, mold oiling is an indispensable step, which requires the use of a specialized oiling tube. This tube rotates, using its internal felt material to evenly apply grease to the mold surface, ensuring good lubrication during production. However, due to prolonged use and grease penetration, the felt inside the oiling tube gradually ages, wears down, and may even accumulate impurities. This directly affects the uniformity and efficiency of oiling, consequently impacting the quality and consistency of capsule production.

[0003] To ensure the continuous stability of oil application to the mold and the high efficiency of production, the felt inside the oiling tube needs to be replaced regularly. However, the traditional felt replacement process is often cumbersome and complicated, involving multiple steps such as disassembling the oiling tube, cleaning or replacing the felt, and reassembling the oiling tube. This is not only time-consuming and labor-intensive, but may also increase human error in the production process.

[0004] Therefore, developing an efficient and convenient felt filling or replacement mechanism to improve the efficiency and accuracy of felt replacement in oiling tubes has become an urgent problem to be solved in the current capsule production field. Utility Model Content

[0005] This invention provides an automatic felt filling machine to solve the problems of cumbersome and inefficient felt replacement process inside the oiling pipe in the prior art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An automatic felt filling machine includes a turntable mechanism that rotates about a horizontally extending axis, and a feeding assembly, a waste ejection assembly, a first filling assembly, a second filling assembly, and a receiving assembly are arranged sequentially around the turntable mechanism.

[0008] The feeding assembly is used to feed the oiling tube into the turntable mechanism, which is used to rotate the oiling tube circumferentially. The waste ejection assembly is used to eject the old felt inside the oiling tube. The first filling assembly and the second filling assembly are used to push the new felt into the oiling tube. The receiving assembly is used to collect the oiling tube after the new felt has been filled.

[0009] It has the following beneficial effects: During the rotation of the turntable mechanism, the feeding component, waste ejection component, first filling component, second filling component and receiving component are operated in sequence, which completes the replacement and filling of the two types of felt inside the oiling pipe. Compared with manual filling of the two types of felt, this method solves the problem of the cumbersome process of replacing the felt inside the oiling pipe and improves production efficiency.

[0010] Furthermore, the turntable mechanism includes a support frame and a disc rotatably mounted on the support frame about a horizontally extending axis, with a groove on the circumferential edge of the disc for installing an oiling pipe.

[0011] The support frame is equipped with an arc-shaped protective plate, the inner side of which forms an inner cavity. The disc rotates within the inner cavity, and the arc-shaped protective plate is used to press against the oiling pipe located in the groove.

[0012] It has the following beneficial effects: by installing the oiling pipe in the groove, the felt inside the oiling pipe can be replaced and filled in sequence by rotating the disc, resulting in high production efficiency.

[0013] Furthermore, the feeding assembly is a funnel, with multiple oiling tubes arranged parallel to each other inside the funnel. The funnel has an inlet and an outlet. The disc rotates intermittently, and when the disc stops, the groove is aligned with the outlet of the funnel so that the oiling tube falls into the corresponding groove.

[0014] It has the following beneficial effects: When using it, simply pour the used oiling tube into the funnel. The distance between the outlet of the funnel and the disc should be smaller than the diameter of the oiling tube. This way, the oiling tube will not fall out of the funnel before the groove rotates to the bottom of the outlet of the funnel.

[0015] Furthermore, the starting end of the arc-shaped protective plate is connected to the discharge port of the funnel.

[0016] Furthermore, the waste ejection assembly includes a first connector fixed to the support frame and a first linear drive component disposed on the first connector, the first linear drive component and the first packing assembly being disposed on opposite sides of the disk;

[0017] The disc rotates intermittently. When the disc stops, the first linear drive is aligned with the corresponding oiling pipe, and the first linear drive moves to extend and retract to push out the old felt inside the oiling pipe.

[0018] It has the following beneficial effects: the extension and retraction of the first linear drive component directly pushes out the old felt in the oiling pipe, eliminating the tedious process of manual handling.

[0019] Furthermore, the support frame is provided with a top pressure plate, which is located between the first linear drive member and the disk. The top pressure plate has a clearance hole for avoiding the first linear drive member, so that the first linear drive member can press down the old felt in the oiling pipe.

[0020] The new felt includes round felt and rectangular felt;

[0021] The first filler assembly includes a feeder for conveying circular felt and a second linear drive for pushing the circular felt into the oiling pipe;

[0022] The second filler assembly includes a bell-shaped coiler and a third linear drive. The coiler is used to hold a rectangular felt. The coiler has a first opening and a second opening. The diameter of the first opening is larger than the diameter of the second opening. The second opening is directly opposite the corresponding oiling tube. The third linear drive is used to drive the rectangular felt to move toward the second opening of the coiler so that the rectangular felt is rolled into a cylindrical shape by the coiler and pushed into the oiling tube.

[0023] It has the following beneficial effects: During filling, one end of the oiling pipe contacts the top pressure plate as a support, which facilitates the subsequent loading of the first and second filling assemblies.

[0024] Furthermore, there is a gap between the starting end and the ending end of the arc-shaped protective plate, which is the discharge area of ​​the turntable mechanism;

[0025] The receiving assembly includes a hopper-shaped component, the open end of which is located at the end of the arc-shaped protective plate to receive the oiling pipe in the groove. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] The following describes various non-limiting embodiments of this utility model. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] like Figure 1 , Figure 2 As shown, an automatic felt filling machine includes a turntable mechanism 2 that rotates about a horizontally extending axis. A feeding assembly 3, a waste ejection assembly 4, a first filling assembly 5, a second filling assembly 6, and a receiving assembly 7 are arranged sequentially around the turntable mechanism 2. The turntable mechanism 2, the feeding assembly 3, the first filling assembly 5, the second filling assembly 6, and the receiving assembly 7 are all fixedly mounted on a frame 1.

[0038] In this embodiment, the feeding assembly 3 is used to feed the oiling tube 17 onto the turntable mechanism 2, the turntable mechanism 2 is used to rotate the oiling tube 17 circumferentially, the waste ejection assembly 4 is used to eject the old felt inside the oiling tube 17, the first filling assembly 5 and the second filling assembly 6 are used to push the new felt into the oiling tube 17, and the receiving assembly 7 is used to collect the oiling tube 17 after the new felt has been filled.

[0039] During the rotation of the turntable mechanism 2, the feeding component 3, waste ejection component 4, first filling component 5, second filling component 6 and receiving component 7 are operated in sequence, completing the replacement and filling of the two types of felt inside the oiling pipe 17. Compared with manual filling of the two types of felt, this method solves the problem of the cumbersome process of replacing the felt inside the oiling pipe 17 and improves production efficiency.

[0040] In this embodiment, as Figure 3 As shown, the turntable mechanism 2 includes a support frame 8 and a disc 9 rotatably mounted on the support frame 8 about a horizontally extending axis. The disc 9 is driven to rotate by a motor via a belt. The disc 9 has a groove 16 on its circumferential edge for installing an oiling pipe 17. After the oiling pipe 17 is installed into the groove 16, the extension direction of the axis of the oiling pipe 17 is consistent with the extension direction of the rotation axis of the disc 9.

[0041] like Figure 3 , Figure 4 As shown, the support frame 8 is equipped with an arc-shaped protective plate 18, the inner side of which forms an inner cavity. The disc 9 rotates within the inner cavity. At this time, the oiling pipe 17 is located between the disc 9 and the arc-shaped protective plate 18. The arc-shaped protective plate 18 is used to press down on the oiling pipe 17 located in the groove 16, preventing the oiling pipe 17 from falling off. By installing the oiling pipe 17 in the groove 16, the felt inside the oiling pipe 17 can be replaced and filled sequentially by the rotation of the disc 9, resulting in high production efficiency.

[0042] In this embodiment, the feeding assembly 3 is a funnel 11, and multiple oiling tubes 17 are arranged with their axes parallel to each other inside the funnel 11. The funnel 11 has an inlet and an outlet. During operation, the disc 9 rotates intermittently. When the disc 9 stops, the groove 16 is aligned with the outlet of the funnel 11, so that the oiling tubes 17 fall into the corresponding grooves 16. In use, simply pour the used oiling tubes 17 into the funnel 11, but it should be ensured that the axes of the oiling tubes 17 inside the funnel 11 are parallel to each other.

[0043] The distance between the outlet of the funnel 11 and the edge of the disc 9 should be smaller than the diameter of the oiling tube 17. This ensures that the oiling tube 17 will not fall out of the funnel 11 before the groove 16 rotates to the point directly below the outlet of the funnel 11.

[0044] The starting end of the arc-shaped protective plate 18 is connected to the outlet of the funnel 11. This prevents the oiling pipe 17 from falling off when it first starts rotating with the disc 9.

[0045] In this embodiment, as Figure 4 As shown, the waste ejection assembly 4 includes a first connector 20 fixed to the support frame 8 and a first linear drive 21 disposed on the first connector 20. The first linear drive 21 and the first filling assembly 5 are respectively placed on opposite sides of the disc 9. The first filling assembly 5 and the second filling assembly 6 are located on the same side of the disc 9. In this way, the first linear drive 21 ejects the old felt from the oiling tube 17 on this side, while the first filling assembly 5 and the second filling assembly 6 push new felt into the oiling tube 17 on the other side. The disc 9 rotates intermittently. When the disc 9 stops, the first linear drive 21 is directly opposite the corresponding oiling tube 17. The first linear drive 21 extends and retracts to eject the old felt from the oiling tube 17. The extension and retraction of the first linear drive 21 directly ejects the old felt from the oiling tube 17, eliminating the tedious process of manual handling.

[0046] The support frame 8 is provided with a top pressure plate 19, which is located between the first linear drive member 21 and the disk 9. The top pressure plate 19 has a clearance hole 22 for avoiding the first linear drive member 21, so that the first linear drive member 21 passes through the clearance hole 22 to press the old felt in the oiling pipe 17, so as to remove the old felt from the oiling pipe 17.

[0047] In this embodiment, the new felt includes a circular felt 28 and a rectangular felt.

[0048] Among them, such as Figure 2 , Figure 5 As shown, the first filling assembly 5 includes a feeder 12 for conveying circular felt 28 and a second linear drive 27 for pushing the circular felt 28 into the oiling pipe 17. The telescopic end of the second linear drive 27 is provided with a suction cup for picking up the circular felt 28.

[0049] The first filler assembly 5 also includes a second connector 13, on which a mounting base 26 is slidably mounted. The mounting base 26 slides on the second connector 13 via a slide rail 25. A second linear drive 27 is mounted on the mounting base 26, and a drive assembly 24 is mounted on the second connector 13. The drive assembly 24 drives the mounting base 26 to move on the second connector 13, thereby moving the second linear drive 27. When the disc 9 pauses intermittently, the second linear drive 27 moves to the position corresponding to the oiling pipe 17, and then extends and retracts, pushing the circular felt 28 into the oiling pipe 17.

[0050] like Figure 2 , Figure 6As shown, the second filler assembly 6 includes a third connector 14, a flared coiler 23, and a third linear drive 29. Both the flared coiler 23 and the third linear drive 29 are arranged on the third connector 14. The coiler 23 holds rectangular felt. The coiler 23 has a first opening and a second opening, with the diameter of the first opening being larger than the diameter of the second opening. The second opening is directly opposite the corresponding oiling pipe 17, and a circular tube 10 is provided at the second opening. The third linear drive 29 drives the rectangular felt to move towards the second opening of the coiler 23, passing through the circular tube 10, causing the rectangular felt to be coiled into a cylindrical shape by the coiler 23, and then pushed into the oiling pipe 17.

[0051] During filling, one end of the oiling pipe 17 contacts the top pressure plate 19 for support, which facilitates the subsequent loading of the first filling assembly 5 and the second filling assembly 6.

[0052] There is a gap between the beginning and end of the arc-shaped protective plate 18. This gap serves as the discharge area of ​​the turntable mechanism 2. That is, the oiling pipe 17, which has completed the filling of new felt, enters the receiving assembly 7 from this gap.

[0053] In this embodiment, the receiving component 7 includes a hopper-shaped component 15, which has a receiving cavity. The open end of the hopper-shaped component 15 is located at the end of the arc-shaped protective plate 18 to receive the oiling tube 17 in the groove 16. The open end is connected to the receiving cavity, and the oiling tube 17 through the interval area can enter the receiving cavity from the open end.

[0054] In this embodiment, the extension and retraction directions of the first linear drive member 21, the second linear drive member 27, and the third linear drive member 29 are consistent with the extension direction of the corresponding oiling pipe 17 axis, and the extension and retraction directions of the first linear drive member 21, the second linear drive member 27, and the third linear drive member 29 are consistent.

[0055] The working process of this utility model is as follows:

[0056] The used oiling tube 17 is placed into the funnel 11. Then the disc 9 rotates intermittently. Each time it pauses, the corresponding groove 16 is always aligned with the outlet of the funnel 11, the corresponding groove 16 is always aligned with the clearance hole 22, the corresponding groove 16 is always aligned with the moved second linear drive 27, the corresponding groove 16 is always aligned with the third linear drive 29, and the corresponding groove 16 is always aligned with the opening end of the bucket-shaped part 15.

[0057] In this way, each time the process is paused, the above steps will always be performed simultaneously. Through automation, work efficiency is improved, and the problem of tedious felt replacement is solved.

[0058] Example 2

[0059] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the extending direction of the axis of the oiling pipe 17 is consistent with the extending direction of the rotating axis of the disk 9. In this embodiment, the extending direction of the axis of the oiling pipe 17 and the extending direction of the rotating axis of the disk 9 form an angle.

[0060] In this embodiment, the extension and retraction directions of the first linear drive member 21, the second linear drive member 27, and the third linear drive member 29 are consistent with the extension direction of the corresponding oiling pipe 17 axis, but the extension and retraction directions of the first linear drive member 21, the second linear drive member 27, and the third linear drive member 29 are inconsistent.
