Description

Technical Field

[0001] This utility model relates to the field of synchronous belt design, specifically to a synchronous toothed belt connection structure. Background Technology

[0002] During the stacking and conveying of medicine packages, the stacked medicine packages need to be transferred to another conveyor belt by a pusher. In order to ensure that the medicine packages can be conveyed stably, the belt needs to be in a state of tension. Since the interface is more fragile than other parts of the belt, it is prone to deformation and breakage. Therefore, the requirements for the interface of the belt to be kept taut during operation are higher.

[0003] The existing belt connection method uses a single pin. During long-term operation, the belt conveyor belt carrying the medicine packets tends to stretch at the belt interface. This stretching causes several problems: firstly, the medicine packets at the belt interface may shift during operation, potentially leading to damage, deformation, or breakage, posing a quality risk to the product; secondly, the damaged medicine packets and materials themselves result in waste. Utility Model Content

[0004] Based on this, the present invention provides a synchronous toothed belt connection structure to solve the technical problem that, during long-term operation, the tensioned belt at the interface is prone to stretching deformation, thus affecting transmission accuracy and stability. The synchronous toothed belt connection structure of the present invention does not exhibit belt stretching at the interface under long-term operation, and can achieve perfect matching with the front and rear inlets and outlets with high precision. Using this synchronous toothed belt connection structure reduces the possibility of belt interface deformation, increases belt lifespan, and effectively saves on belt replacement costs.

[0005] To achieve the above objectives, this utility model provides a synchronous toothed belt connection structure, including a synchronous toothed belt body, which has a planar structure on the front and a toothed groove structure on the back. The toothed groove structure is composed of a plurality of toothed racks that are integral with the synchronous toothed belt body and are equally spaced. The synchronous toothed belt body has a first end and a second end for interconnection. The width of the first end is narrower than that of the synchronous toothed belt body. The second end has a connecting groove that opens towards the first end and matches the shape of the first end. The first end is inserted into the connecting groove and connected to the second end to form a connecting part.

[0006] The toothed structure of the connecting part corresponds to at least two toothed racks. At least a portion of the toothed racks in the connecting part have a first groove along their length direction on their top. The front of the connecting part has a second groove opposite to the first groove. The first groove and the second groove are respectively inlaid with a first fixing plate and a second fixing plate. The first fixing plate and the second fixing plate are locked together by screws.

[0007] As a further preferred technical solution of this utility model, the first fixing plate has a stud protruding towards the second fixing plate, and the second fixing plate has a screw hole corresponding to the stud, and the screw passes through the screw hole and is screwed to the stud.

[0008] As a further preferred technical solution of this utility model, the first fixing plate and the second fixing plate are locked together by at least three screws, one of which is located in the area of ​​the connecting groove, and the other two screws are respectively located in the areas on both sides of the connecting groove.

[0009] As a further preferred technical solution of this utility model, the first fixing plate is embedded in the first groove and is flush with the top of the first groove, and the second fixing plate is embedded in the second groove and is flush with the front of the synchronous toothed belt body.

[0010] The synchronous toothed belt connection structure of this utility model, by adopting the above technical solution, can achieve the following beneficial effects:

[0011] The synchronous toothed belt connection structure of this utility model ensures that the belt interface does not elongate under long-term operation, and can perfectly match the front and rear inlets and outlets with high precision. By adopting the synchronous toothed belt connection structure of this utility model, the possibility of belt interface deformation can be reduced, the service life of the belt can be increased, and thus the cost of belt replacement can be effectively saved.

[0019] like Figure 1-Figure 3 As shown, this utility model provides a synchronous toothed belt connection structure, including: a synchronous toothed belt body 1, which has a planar structure on the front and a toothed groove structure on the back. The toothed groove structure is composed of a plurality of toothed racks 7 that are integral with the synchronous toothed belt body 1 and are equally spaced. The length direction of the toothed racks 7 is the width direction of the synchronous toothed belt body 1. The synchronous toothed belt body 1 has a first end 3 and a second end 2 for mutual connection. The width of the first end 3 is narrower than that of the synchronous toothed belt body 1. The second end 2 is provided with a connecting groove 10 that opens towards the first end 3 and matches the shape of the first end 3. The first end 3 is inserted into the connecting groove 10 and connected to the second end 2 to form a connecting part.

[0020] The toothed structure of the connecting part corresponds to eleven racks 7, nine of which have a first groove 8 along their length on their top. The opening of the first groove 8 is located at the top of the rack 7. The front of the connecting part has a second groove 4 opposite to the first groove 8. The first groove 8 and the second groove 4 are respectively fitted with a first fixing plate 9 and a second fixing plate 5. The first fixing plate 9 has a stud protruding towards the second fixing plate 5. The second fixing plate 5 has a screw hole corresponding to the stud. A screw 6 passes through the screw hole and is screwed to the stud. The first fixing plate 9 and the second fixing plate 5 are locked together by three screws 6. One screw 6 is located in the area inside the connecting groove 10, and the other two screws 6 are located on both sides of the connecting groove 10. The use of screws is a conventional technology. It should be understood that when screws are used to fix the first fixing plate 9 and the second fixing plate 5, holes corresponding to the screws 6 or studs are provided on the first end 3 and the second end 2. The structure described above in this utility model can fix the first end 3 and the second end 2 together, thereby reducing the possibility of belt interface deformation, increasing the service life of the belt, and thus effectively saving the cost of belt replacement.
