[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-6 As shown, a checkweigher conveyor belt with a quick-release locking structure includes a frame 1 and a conveying mechanism 2. The conveying mechanism 2 includes a conveying frame 21 and a tensioning roller 23. One side of the conveying frame 21 is hinged to the frame 1, and the other side is fixed to the frame 1 in an open and close manner through a quick-release structure. The tensioning roller 23 is movably connected to the conveying frame 21, and the tensioning roller 23 and the conveying frame 21 tighten / relax the belt through relative movement.

[0025] This solution sets a quick-release structure so that one side of the conveying mechanism 2 can be separated from the frame 1 through the quick-release structure. After separation, a gap is formed on one side to facilitate the disassembly and assembly of the belt. The other side of the conveying mechanism 2 is hinged to the frame 1. The belt is loosened by the tensioning roller 23 and can be removed from the notch. The operation is convenient and is conducive to rapid disassembly and replacement, which greatly improves the working efficiency of the checkweigher for the entire production line.

[0026] The side of the conveying frame 21 is provided with an axially rotating rotating rod 11, and a mounting seat 12 for mounting the frame 1 is provided on the rotating rod 11. Specifically, the conveying mechanism 2 and the frame 1 are connected through the rotating rod 11 and the mounting seat 12. The mounting seat 12 is arranged corresponding to the conveying frame 21, and the two can be fixed by means of a bayonet, a buckle, a bolt, etc. After being fixed, a hinged connection structure is formed between the conveying frame 21 and the frame 1. Among them, the rotating rod 11 can also be provided with a rotation damping, or a spring structure, so that after the quick-release structure is disassembled, the conveying frame 21 can be automatically maintained after being rotated to a certain angle, so as to achieve the following effect: Figure 5 The status shown.

[0027] As a feasible embodiment, the quick-release structure includes at least one shaft rod 25 rotatably arranged in the conveying frame 21, and a first extension portion is provided on the surface of the shaft rod 25, and the first extension portion is provided with a locking pin 26 axially parallel to the shaft rod 25, wherein a locking slot 14 corresponding to the locking pin 26 is provided on the frame 1, and the shaft rod 25 rotates so that the locking pin 26 enters the locking slot 14. This scheme proposes a specific quick-release structure, by rotating the shaft rod 25, the shaft rod 25 rotates and drives the locking pin 26 to enter the locking slot 14. Specifically, as shown in the figure, a rotating slot 13 is provided on the frame 1 to accommodate the shaft rod 25. When the shaft rod 25 enters the rotating slot 13, the shaft rod 25 rotates in the rotating slot 13, so that the locking pin 26 is locked along the locking slot 14. This embodiment provides an arc-shaped locking slot 14, and the shaft rod 25 and the locking pin 26 are respectively located in two slots to form a locking force. A connecting rib is provided between the two connecting rods 24 , and a handle 27 is provided at the end of the shaft rod 25 .

[0028] In order to further improve the quick-release effect, the relative movement between the tensioning roller 23 and the conveying frame 21 is driven by the quick-release structure. By setting a linkage structure, the quick-release structure can directly tighten the belt when locking and directly release the belt when disassembling.

[0029] Specifically, the shaft 25 is axially parallel to the tensioning roller 23, and the axial end of the tensioning roller 23 is slidably connected to the conveying frame 21 through the sliding portion 22. A second extension portion is provided on the surface of the shaft 25 near the tensioning roller 23. The second extension portion and the sliding portion 22 are hinged through a connecting rod 24. As a feasible linkage structure, when the shaft 25 rotates, the second extension portion forms a crankshaft rotation path, driving the connecting rod to push the sliding portion, causing the sliding portion to translate to tighten / relax the belt, wherein the second extension portion can be shared with the first extension portion (such as Figure 6 As shown), they can also be set separately, but when they are shared, the locking pin 26, the shaft 25 and the hinge axis of the second extension portion cannot be located in the same plane.

[0030] As another embodiment, an eccentric block (not shown in the figure) can be provided on the surface of the shaft 25 instead of the connecting rod 24. By rotating the shaft 25, the eccentric block can directly contact and squeeze the sliding part 22, which can also achieve the same tightening effect.

[0031] The specific implementation method is as follows: when the belt needs to be removed, the handle 27 is rotated so that the locking pin 26 leaves the locking slot 14. At the same time, the connecting rod 24 drives the sliding part 22 to slide in the direction of loosening the belt, and rotates toward the conveyor frame 21 to create a gap. The belt is removed from the separated gap, and a new belt is replaced and the installation can be completed by reversing the operation. The locking / disassembly of the conveyor frame 21 is completed only through the quick-release structure, and the tightening / relaxing of the belt is completed at the same time.

[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
