[0002] A production line composed of a double-speed chain conveyor is usually called a gravity-flow conveying system with a double-speed chain conveyor. It is mainly used for material conveying in assembly and processing production lines. Its conveying principle is to use the speed-increasing function of the double-speed chain to make the tooling plate supporting the goods on it run quickly and stop at the corresponding operating position by the stopper; or to complete the accumulation action, transfer, indexing, and line transfer functions by corresponding instructions.

[0003] In the existing technology, the double-speed chain is a commonly used chain. A conveyor line composed of multiple double-speed chains can realize the function of rapid product transportation. However, when using a traditional double-speed chain, the sprockets are directly exposed to the outside environment, which may cause external debris to fall into the double-speed chain and damage it, or workers may accidentally touch the rotating sprockets, thus reducing safety.

[0004] Therefore, this utility model proposes a protection mechanism for a double-speed chain to solve the above problems. Utility Model Content

[0007] A threaded tube has a rotating plate fitted on its surface, a protective plate on the end face of the rotating plate, a positioning screw screwed into the inside of the threaded tube, and a limit spring fitted on the surface of the threaded tube.

[0008] Preferably, the support frame has a movable plate on its side. The movable plate has an arc-shaped plate structure, and a limit opening is formed on the surface of the movable plate. Multiple sets of threaded grooves are formed, and the multiple sets of threaded grooves are arranged linearly at equal intervals about the surface of the support frame.

[0009] Preferably, the rotating plate can rotate around the threaded pipe, and a traction rod is provided at the bottom of the rotating plate, which can be displaced within the limiting port.

[0010] Preferably, the threaded tube surface is provided with a base plate, one end of the limiting spring is fixedly connected to the bottom of the base plate, the other end of the limiting spring is fixedly connected to the surface of the rotating plate, and the positioning screw can be screwed into the threaded groove.

[0011] Preferably, the protective plate has a square plate structure with rounded corners on the end face and corrugated plates on the side. The corrugated plates can be compressed and folded. There are two sets of corrugated plates, which are symmetrically distributed about the protective plate.

[0012] Preferably, the positioning frame is fixedly connected to the surface of the double-speed chain by bolts, and the surface of the positioning frame is provided with a processing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a protective mechanism for a double-speed chain. In use, the protective plate is first screwed into the threaded groove by a positioning screw, so that the protective plate covers the top of the double-speed chain. Then, multiple sets of protective plates can protect the double-speed chain, thus preventing external debris from falling directly into the double-speed chain. The protective plate can rotate, which also facilitates the movement of the positioning frame through the double-speed chain, and prevents the protective plate from affecting the displacement effect of the positioning frame.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a protection mechanism for a double-speed chain, the protection mechanism for the double-speed chain includes: a conveyor body 1, a support frame 2 is provided on the side of the conveyor body 1, a double-speed chain 3 is provided inside the support frame 2, a threaded groove 4 is opened on the surface of the support frame 2, and a positioning frame 5 is provided on the surface of the double-speed chain 3.

[0023] A threaded tube 6 is fitted with a rotating plate 7 on its surface. A protective plate 9 is provided on the end face of the rotating plate 7. A positioning screw 8 is screwed into the threaded tube 6. A limiting spring 10 is fitted on the surface of the threaded tube 6.

[0024] First, the positioning screw 8 can be screwed into the threaded groove 4, so that the protective plate 9 can cover the top of the double speed chain 3. Then, multiple sets of protective plates 9 can protect the double speed chain 3 and provide a shielding effect, preventing external debris from falling directly into the double speed chain 3. The protective plate 9 can rotate, which also facilitates the positioning frame 5 to be transported and moved by the double speed chain 3, and prevents the protective plate 9 from affecting the displacement effect of the positioning frame 5.

[0025] Example 2: Based on Example 1, a protective plate 9 is provided to protect the double-speed chain 3. The rotating plate 7 can rotate around the threaded tube 6. A traction rod 13 is provided at the bottom of the rotating plate 7. The traction rod 13 can be displaced within the limiting port 12. A base plate 14 is provided on the surface of the threaded tube 6. One end of the limiting spring 10 is fixedly connected to the bottom of the base plate 14, and the other end of the limiting spring 10 is fixedly connected to the surface of the rotating plate 7. The positioning screw 8 can be screwed into the threaded groove 4. The protective plate 9 has a square plate structure. The end face of the protective plate 9 is rounded. A corrugated plate 15 is provided on the side of the protective plate 9. The corrugated plate 15 can be compressed and folded. Two sets of corrugated plates 15 are provided. The two sets of corrugated plates 15 are symmetrically distributed about the protective plate 9.

[0026] In use, the upper part of the double speed chain 3 can be covered by the protective plate 9 and the corrugated plate 15 to prevent external debris from falling into the double speed chain 3 and causing damage. The corrugated plate 15 can increase the sealing effect at the gap between the protective plates 9. When the conveyor body 1 is started and the double speed chain 3 is rotated, the positioning frame 5 can push the protective plate 9. The rotating plate 7 can rotate around the threaded tube 6, so that the protective plate 9 can rotate and avoid conflict with the movement of the positioning frame 5. The setting of the limit spring 10 can make the protective plate 9 automatically reset after rotation. The traction rod 13, together with the limit port 12, can limit the rotation angle of the protective plate 9.

[0027] Example 3: Based on Example 2, a positioning screw 8 is provided for the protective plate 9 to facilitate installation. A movable plate 11 is provided on the side of the support frame 2. The movable plate 11 has an arc-shaped plate structure. A limit opening 12 is opened on the surface of the movable plate 11. Multiple sets of threaded grooves 4 are opened. The multiple sets of threaded grooves 4 are arranged linearly at equal intervals on the surface of the support frame 2. The positioning frame 5 is fixedly connected to the surface of the double speed chain 3 by bolts. A processing plate 16 is provided on the surface of the positioning frame 5.

[0028] When in use, the positioning screw 8 can be rotated so that one end of the positioning screw 8 can be screwed into the threaded groove 4, which can easily fix the protective plate 9 and protect the double speed chain 3. When the protective plate 9 needs to be removed, the positioning screw 8 can be taken out from the threaded groove 4, and then the positioning screw 8 can be taken out from the threaded tube 6 to separate the positioning screw 8 from the threaded tube 6.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
