Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of edible fungus machinery, in particular to a structural improvement of a linkage type fungus bag opening device. Background Art
[0002] The edible mushroom bag opener has been widely used in the edible mushroom cultivation industry to replace manual opening of mushroom bags. The Chinese utility model patent with the authorization announcement number CN214430687U discloses a "linked mushroom bag opening device". The hinge point between the cutter wheel frame and the cutter wheel seat is set in the middle, and the cutter wheel is set at the free end near the edge. Due to the problems of processing tolerance and production assembly control in actual production, and the amount of left and right swing of the cutter wheel frame is only limited by the hinge point between it and the cutter wheel seat, the left and right swing clearance of the cutter wheel set at the far end is very large, which makes it easy for adjacent cutter wheels to disengage in actual production, affecting the use effect. Once the cutter wheel disengages, the position of the hole in the mushroom bag will be disordered, thereby affecting the quality of the hole punching in the mushroom bag. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a linkage type mushroom bag opening device with good use effect.
[0004] The technical solution of the utility model is: a linkage mushroom bag opening device, including a cutter wheel, a cutter wheel frame and a cutter wheel seat, one end of the cutter wheel frame is hinged with a hinged part, the other end is provided with a through hole, and a cutter wheel connecting part is provided near the middle position, the cutter wheel is rotatably connected to the cutter wheel connecting part of the cutter wheel frame through a cutter wheel shaft, the hinged part of the cutter wheel frame is fixedly connected to the cutter wheel seat, the other end of the cutter wheel frame is connected to the cutter wheel seat through a guide column, the guide column passes through the through hole at the end of the cutter wheel frame, one end is fixedly connected to the cutter wheel seat, and the other end is sleeved with a spring to press against the cutter wheel frame to apply an inward force to the cutter wheel frame.
[0005] The technical effect of the utility model is that it has the advantages of simple structure, reasonable design, reliable engagement of the cutter wheel and not easy to disengage, and can quickly open a uniform and neat herringbone opening on the surface of the edible fungus bag. The cutter wheel is arranged in the middle of the cutter wheel frame, and both ends of the cutter wheel frame are connected to the cutter wheel seat, so that the displacement of the cutter wheel to the left and right is simultaneously limited by the connection points at both ends of the cutter wheel frame, so that the clearance of the cutter wheel to the left and right is much smaller than that of the existing one-point fixed structure, and the cutter wheel will no longer disengage from the mutual engagement during operation. It solves the problem that the existing linkage bag opener cutter wheel is easy to disengage, which affects the punching quality of the bag. The cutter wheel frame and the cutter wheel seat can be quickly assembled or disassembled, which improves production efficiency and reduces maintenance difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] like Figures 1 to 4 As shown, a linkage mushroom bag opening device comprises a cutter wheel 1, a cutter wheel frame 2 and a cutter wheel seat 3. The cutter wheels are mutually linked by teeth meshing arranged on the side. One end of the cutter wheel frame 2 is hinged with a hinged portion 4, the other end is provided with a through hole, and a cutter wheel connecting portion 5 is provided near the middle position. The cutter wheel 1 is rotatably connected to the cutter wheel connecting portion 5 of the cutter wheel frame 2 through a cutter wheel shaft. The hinged portion 4 of the cutter wheel frame 2 is fixedly connected to the cutter wheel seat 3. The other end of the cutter wheel frame 2 is connected to the cutter wheel seat 3 through a guide column 6. The guide column 6 passes through the through hole at the end of the cutter wheel frame 2, one end is fixedly connected to the cutter wheel seat 3, and the other end is sleeved with a spring 7 against the cutter wheel frame 2 to apply an inward force to the cutter wheel frame 2. The hinged portion of the cutter wheel frame is connected to the cutter wheel seat by screws, and the cutter wheel frame can swing outward along the hinged axis between it and the hinged portion. When the mushroom bag is opened, it passes through the cutter wheels. The cutter wheel is squeezed by the mushroom bag and moves outward adaptively, and then resets inward under the action of the spring force.
[0011] The cutter wheel seat 3 is connected with a fixing ring 9 through a bracket 8, and the guide column 6 is fixedly connected to the cutter wheel seat 3 through the fixing ring 9. The fixing ring structure can simplify the processing technology, and the structure can also be replaced by a structure with a hole in the cylinder, so that the cutter wheel can pass through without motion interference.
[0012] The guide column 6 is provided with an adjusting nut 10 for adjusting the elastic force of the spring 7 .
[0013] A driving gear 11 is provided on one of the cutter wheel frames 2. The driving gear 11 meshes with the teeth of the cutter wheel 1 on the cutter wheel frame 2, and the cutter wheel can be driven to rotate together through the driving gear.
[0014] The driving gear 11 is a double gear, and the teeth of the double gear are respectively meshed with the teeth on both sides of the cutter wheel 1. The driving gear is connected to a driving device to drive the cutter wheel to rotate.
