Description

Technical Field

[0001] This utility model relates to edible fungi machinery, and in particular to a double-sided perforation driving device for mushroom bags, belonging to the field of mechanical technology. Background Technology

[0002] In the cultivation of edible fungi, holes need to be punched in the mushroom bags before inoculation. Currently, high-efficiency mushroom bag punching machines are generally used for punching these holes, which are more efficient and standardized than manual operation. Several technical solutions for mushroom bag punching machines have been disclosed in Chinese patent literature, such as CN104509372A Automatic Mushroom Bag Punching Machine and CN103314772A. Automatic punching machines for mushroom cultivation bags, etc., use a punching needle connected to a linear drive mechanism to punch holes in the bags. The punching operation is achieved through the movement of the linear drive. Before punching, the punching area of ​​the bag often needs to be flattened. This flattening operation is generally achieved by another linear drive mechanism driving a pressing plate. In existing punching machine drives, most linear drive mechanisms are multiple sets, and the drive source is mostly cylinder drive. This method has the following problems: First, cylinder drive is noisy and causes relatively large vibrations to the equipment; second, if punching holes on multiple sides of the bag, using multiple cylinders requires more cylinders, and their synchronization is difficult to guarantee; third, the cylinders are generally located in the same space as the bags, and the cylinders may produce oil mist during use, which may pollute the environment and the mushroom spawn, affecting the normal growth of edible fungi. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned problems in existing edible mushroom punching drives and to provide a double-sided punching drive device for mushroom bags.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a double-sided perforation driving device for mushroom bags, including a frame and multiple perforation heads, with two identical flattening and perforation mechanisms arranged on both sides of the frame; a mushroom bag conveyor belt passes between the two flattening and perforation mechanisms, wherein each flattening and perforation mechanism includes two left-right guide rails, with sliders fitted on the guide rails, a perforation frame fixedly connected to the sliders, multiple perforation heads fixedly connected to the perforation frame, and two up-down fixed shafts fixedly installed at the outer end of the frame, each fixed shaft having a rotatable crank arm, and a cam hole provided on the crank arm. Two vertical levers are fixedly connected to the outer end of the punch holder. The levers are slidably inserted into the cam holes. Both ends of the first connecting rod are fixedly connected to rod end spherical bearings. The inner ring of the spherical bearing at the outer end of the first connecting rod is tightly fitted onto the first shaft in the vertical direction, which is fixedly connected to the inner end of the crank arm. The inner ring of the spherical bearing at the inner end of the first connecting rod is tightly fitted onto the second shaft in the vertical direction, which is fixedly connected to the flattening frame. The flattening frame is located inside the punch holder. The pressure plate is fixedly connected to the flattening frame. The flattening frame and the pressure plate have corresponding holes for the punch head to pass through. The punch holder is driven by a linear reciprocating drive mechanism.

[0005] Furthermore, the linear reciprocating drive mechanism comprises: a motor with a reducer fixedly mounted on the frame; a drive gear fixedly mounted on the output shaft of the motor; a driven gear rotatably mounted next to the drive gear; the driven gear meshes with the drive gear and the transmission ratio is 1:1; an eccentric shaft is fixedly mounted on both the drive gear and the driven gear; rod end spherical bearings are fixedly connected to both ends of the second connecting rod; a horizontally forward-backward connecting shaft is fixedly connected to the punching frame; the inner ring of the spherical bearing at the outer end of the second connecting rod is tightly fitted onto the connecting shaft; the inner ring of the spherical bearing at the inner end of the second connecting rod is tightly fitted onto the eccentric shaft; when the motor rotates, the eccentric shaft drives the punching frame to reciprocate left and right through the second connecting rod.

[0006] Furthermore, multiple guide tubes are fixedly connected to the flattening frame and flattening plate, with the guide tubes corresponding to the punching heads on the left and right. When punching, the punching heads pass through the guide tubes.

[0007] Furthermore, two identical flattening and perforating mechanisms are symmetrically arranged about the left and right center lines of the mushroom bag conveyor belt.

[0008] Furthermore, the drive gear and the driven gear are symmetrically arranged about the left and right center lines of the mushroom bag conveyor belt.

[0017] As shown in the attached diagram, a double-sided perforation driving device for mushroom bags includes a frame 1 and multiple perforation heads 11. Two identical flattening and perforating mechanisms are arranged on both sides of the frame. A mushroom bag conveyor belt 20 passes between the two flattening and perforating mechanisms. The mushroom bag conveyor belt is present on existing inoculation machines, such as a conveyor belt driven by a servo motor. The two identical flattening and perforating mechanisms are symmetrically arranged about the left and right center lines of the mushroom bag conveyor belt. The flattening and perforating mechanism includes two left and right guide rails 2, with sliders 3 fitted on the guide rails. A perforation frame 4 is fixedly connected to the sliders. Multiple perforation heads 11 are fixedly connected to the perforation frame. Two up and down fixed shafts 22 are fixedly installed at the outer end of the frame. A crank arm 6 is rotatably mounted on each fixed shaft. A cam hole 7 is opened on the crank arm. Two vertical levers 5 are fixedly connected to the outer end. The levers are slidably inserted into the cam hole. Both ends of the first connecting rod 8 are fixedly connected to rod end spherical bearings. The inner ring of the spherical bearing at the outer end of the first connecting rod 8 is tightly fitted to the first shaft 9 in the vertical direction, which is fixedly connected to the inner end of the crank arm. The inner ring of the spherical bearing at the inner end of the first connecting rod is tightly fitted to the second shaft 10 in the vertical direction, which is fixedly connected to the flattening frame 12. The flattening frame is located inside the punching frame. The pressing plate 13 is fixedly connected to the flattening frame. The flattening frame and the pressing plate have corresponding holes for the punching head to pass through. The punching frame is driven by a linear reciprocating drive mechanism. In this embodiment, multiple guide tubes 14 are fixedly connected to the flattening frame and the pressing plate. The guide tubes 14 correspond to the punching head on the left and right. When punching, the punching head passes through the guide tube.

[0018] In this embodiment, the linear reciprocating drive mechanism is as follows: a motor 18 with a reducer is fixedly installed on the frame, a drive gear 17 is fixedly installed on the output shaft of the motor, and a driven gear 16 is rotatably installed next to the drive gear. The drive gear and the driven gear mesh with each other. The drive gear and the driven gear are symmetrically arranged about the left and right center lines of the mushroom bag conveyor belt. The driven gear meshes with the drive gear and the transmission ratio is 1:1. An eccentric shaft 21 is fixedly installed on both the drive gear and the driven gear. Both ends of the second connecting rod 19 are fixedly connected with rod end joint bearings. A horizontal front-back connecting shaft 15 is fixedly connected to the punching frame. The inner ring of the joint bearing at the outer end of the second connecting rod is tightly fitted on the connecting shaft 15, and the inner ring of the joint bearing at the inner end of the second connecting rod is tightly fitted on the eccentric shaft 21. When the motor rotates, the eccentric shaft drives the punching frame to move left and right reciprocally through the second connecting rod.

[0019] The working process of this device is as follows: After the mushroom bags are transported to the position by the mushroom bag conveyor belt, the motor rotates, and the active gear and passive gear rotate synchronously. During the rotation, the eccentric shaft drives the punching frame to move inward through the second connecting rod. When the punching frame moves, the lever drives the crank arm to rotate along the fixed shaft. During the rotation of the crank arm, the pressure plate moves inward through the first connecting rod to flatten the mushroom bags. The punching frame continues to move inward to drive the punching head to complete the punching operation. The gear continues to rotate to drive the punching frame to retract outward to return to its original position. During the reset process, the lever drives the crank arm to reset through the cam hole, thus completing one punching operation.
