Description

Technical Field

[0001] This utility model relates to the field of rotary joints, and more specifically to a rotary joint that can be used as a drive end. Background Technology

[0002] A rotary joint is a rotatable joint used for transferring materials. The rotary joint delivers the materials into a material container, and a mixing mechanism is required to mix the various materials that are transferred sequentially.

[0003] Rotary joints can only transfer materials and cannot drive the mixing mechanism to mix materials. There is a technical problem that the rotary joint and the driving part of the mixing mechanism can be used independently. There is an urgent need to design a rotary joint that can be used as the driving end.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] The purpose of this invention is to provide a rotary joint that can be used as a drive end, thereby solving the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary joint that can be used as a drive end includes:

[0008] The rotating center shaft includes an upper transmission part and a lower transmission part connected to the rotating mechanism, and the rotating center shaft also includes an inlet and an outlet that are interconnected.

[0009] Bearings;

[0010] The housing includes a mounting groove for mounting a rotating central shaft and a feed pipe for supplying material to the inlet so that the material is suitable for discharge from the outlet.

[0011] A connecting flange is located at the end of the lower drive section away from the upper drive section, and the connecting flange is adapted to be connected to the stirring mechanism.

[0012] In one alternative embodiment, the rotation center shaft extends through the outer casing;

[0013] The side of the rotation center shaft is rotatably connected to the outer casing via a bearing.

[0014] In one alternative embodiment, the upper transmission part includes a connecting groove for mounting the power shaft of the rotating mechanism;

[0015] The end of the lower transmission unit is inserted into the middle hole of the connecting flange.

[0016] In one alternative embodiment, the center of the connecting groove is concentric with the center of the bearing;

[0017] The lower transmission unit is welded to or screwed to the connecting flange.

[0018] In one alternative embodiment, the discharge channel extends through the end of the lower transmission unit away from the upper transmission unit;

[0019] The feed inlets are evenly distributed on the side of the lower transmission part so that multiple feed inlets can sequentially receive the material supplied by the feed pipe when the rotating central shaft rotates.

[0020] In one alternative implementation, the discharge channel is separated from the connecting groove;

[0021] The inlet is located at the end of the outlet channel;

[0022] The inlet is located inside the mounting slot.

[0023] In one alternative embodiment, the connecting flange is located outside the housing;

[0024] The feed pipe is located above the mounting slot.

[0025] In one optional embodiment, the junction of the feed pipe and the mounting groove forms a storage cavity;

[0026] The storage chamber is connected to both the inlet and the feed pipe, and is used to temporarily store materials when the feed pipe and the inlet are separated during the rotation of the central shaft.

[0027] The beneficial effects of this utility model are as follows: It provides a rotary joint that can be used as a drive end. By using a rotating central shaft, bearing, housing and connecting flange in cooperation, a rotary joint that can be used as a drive end is made to replace the independent rotary joint and the drive part of the stirring mechanism. This achieves the effect that the rotary joint can drive the stirring mechanism to work while conveying materials. The rotary joint and the drive part of the stirring mechanism are combined into one, which reduces the cost of the device. Since the rotary joint conveys materials while rotating, it improves the degree of mixing of materials after stirring. Attached Figure Description

[0038] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] refer to Figure 1 At least one embodiment provides a rotary joint that can be used as a drive end, comprising: a rotating central shaft 1, which includes an upper transmission part 11 and a lower transmission part 13 connected to a rotating mechanism, the lower transmission part 13 being used to drive a connecting flange 4 and a stirring mechanism to rotate, thereby realizing the stirring of materials; the rotating central shaft 1 also includes an inlet 14 and an outlet 15 communicating with each other, serving as a channel for material transmission and receiving materials provided by a feed pipe 32; a bearing 2, used to reduce the frictional force when the rotating central shaft 1 rotates; and a housing 3, which includes a mounting groove 31 for mounting the rotating central shaft 1 and A feed pipe 32 provides material to the inlet 14 so that the material is suitable for discharge from the outlet 15. The mounting groove 31 is used to provide the mounting position of the rotating center shaft 1. The feed pipe 32, the inlet 14, and the outlet 15 form a material conveying channel. A connecting flange 4 is located at the end of the lower transmission part 13 away from the upper transmission part 11. The connecting flange 4 is suitable for connection with the stirring mechanism to drive the stirring mechanism to stir the material. The inlet 14 is connected to an external control system to receive the material to be conveyed. The outer shell 3 is installed on the material collection bucket.

[0040] In some embodiments, the rotating central shaft 1 passes through the outer shell 3 to facilitate connection with the rotating mechanism and the stirring mechanism; the side of the rotating central shaft 1 is rotatably connected to the outer shell 3 through the bearing 2 to reduce the friction when the rotating central shaft 1 rotates.

[0041] In some embodiments, the upper transmission part 11 includes a connecting groove 12 for mounting the power shaft of the rotating mechanism, for connecting with the power shaft of the rotating mechanism; the end of the lower transmission part 13 is inserted into the middle hole of the connecting flange 4.

[0042] In some embodiments, the center of the connecting groove 12 is concentric with the center of the bearing 2 to ensure good stability during rotation; the lower transmission part 13 is welded to or screwed to the connecting flange 4.

[0043] In some embodiments, the discharge channel 15 passes through the end of the lower transmission part 13 away from the upper transmission part 11 to facilitate material discharge; the inlet 14 is evenly distributed on the side of the lower transmission part 13 so that when the rotation center shaft 1 rotates, the multiple inlets 14 sequentially receive the material provided by the feed pipe 32.

[0044] In some embodiments, the discharge channel 15 is separated from the connecting groove 12 to prevent material from contacting the power shaft of the rotating mechanism; the inlet 14 is located at the end of the discharge channel 15; the inlet 14 is located in the mounting groove 31.

[0045] In some embodiments, the connecting flange 4 is located outside the housing 3; the feed pipe 32 is located above the mounting groove 31 to ensure that the material provided by the feed pipe 32 moves under the action of gravity.

[0046] In some embodiments, the intersection of the feed pipe 32 and the mounting groove 31 forms a storage cavity 33 for temporarily storing materials; the storage cavity 33 is connected to both the inlet 14 and the feed pipe 32, and is used to temporarily store materials when the feed pipe 32 is separated from the inlet 14 when the rotating central shaft 1 rotates, so as to avoid the materials from blocking the mounting groove 31.

[0047] Working principle: Before using a rotary joint that can be used as a drive end, connect the connecting groove 12 of the upper transmission part 11 to the power shaft of the rotating mechanism; connect the feed pipe 32 to the external feeding system; simultaneously fix the connecting flange 4 to the stirring mechanism; and ensure that the discharge channel 15 is connected to the channel in the center of the stirring mechanism; when using a rotary joint that can be used as a drive end, the external feeding system transmits materials through the feed pipe 32, the materials reach the storage chamber 33, and then reach the discharge channel 15 through the inlet 14; finally, they reach the collection bucket from the discharge channel 15 through the rotating mechanism; during this process, the rotating mechanism drives the upper transmission part 11 and the lower transmission part 13 to rotate, so that multiple inlets 14 are connected to the storage chamber 33 in sequence; the centrifugal force generated by the rotation of the stirring mechanism causes the materials to leave the stirring mechanism from the opening on its side; the rotation of the stirring mechanism simultaneously achieves uniform mixing of the materials in the collection bucket; maintain the above process until the end of the work.
