Description

Technical Field

[0001] This utility model relates to edible fungi machinery, and in particular to a bag conveying mechanism on an inoculation machine, belonging to the field of biomechanical technology. Background Technology

[0002] In edible mushroom production, machinery can significantly reduce costs and improve efficiency and quality by replacing manual labor. Among these machines, the edible mushroom inoculation machine is a crucial piece of equipment. Currently, various structures of edible mushroom inoculation machines exist on the market. Mushroom inoculation requires multiple steps, such as punching, inoculation, and pressing. The inoculation site must correspond to the punching site. Therefore, the inoculation machine needs to precisely transport and move the mushroom bags to the corresponding positions. Generally, a ring-shaped conveyor mechanism is used to transport the mushroom bags, such as the multi-station fully automatic inoculation machine disclosed in CN106416758A. The mushroom bags are located on the ring conveyor device, relying on sensors to identify and position them. However, the dust environment in the inoculation machine is relatively high, making the sensors prone to false alarms. Furthermore, the mechanism's support is unstable due to the impact on the ring conveyor device during punching, potentially causing deviations in the inoculation and punching positions. CN210076169U discloses a double-sided inoculation edible mushroom inoculation machine, which also suffers from the above problems. CN209660090U... The publicly available edible mushroom inoculation machine uses a roller conveyor for transport, which requires a specially configured mushroom bag frame, and the roller conveyor may slip. Summary of the Invention

[0003] The purpose of this invention is to provide a bag delivery mechanism for an inoculation machine.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a bag conveying mechanism on an inoculation machine includes a frame, a geared motor fixedly installed at one end of the frame, a drive sprocket fixedly connected to the output end of the geared motor, a driven sprocket corresponding to the drive sprocket rotatably connected to the other end of the frame, a sprocket-type idler wheel and a tensioning sprocket rotatably installed on the frame; a chain wraps around the drive sprocket, driven sprocket, idler wheel and tensioning sprocket, the geared motor is a servo geared motor, multiple bag pushing devices are fixedly connected to the chain, the multiple bag pushing devices are evenly distributed along the length of the chain, the pushing device includes a U-shaped part fixedly connected to the bottom of the chain, and a bag pushing wheel rotatably installed at the opening of the U-shaped part; a front-to-back groove rail is fixedly installed on the frame, the bottom surface of the groove rail has an elongated through hole running through the front and back, the chain is located below the elongated through hole, and when the chain moves, the bag pushing device passes through the through hole.

[0005] Furthermore, multiple elastic pressure roller mechanisms are installed on the frame above the trough rail. Each elastic pressure roller mechanism includes a U-shaped wheel frame with its opening facing downwards. A dumbbell-shaped pressure roller is rotatably connected to the opening of the U-shaped wheel frame, with the roller's axis pointing left to right. At least two bolts in the vertical direction are fixedly connected to the U-shaped wheel frame. The frame has a bolt connection part with bolt through holes through which the bolts pass. An adjusting nut is screwed onto the upper part of the bolt. A compression spring is threaded through the bolt between the bolt connection part and the U-shaped wheel. When the mushroom bag passes through the trough rail, it contacts the pressure roller.

[0006] Furthermore, a zero-position switch is fixedly installed on the frame, and an inductor that senses the zero-position switch is fixedly installed on the chain. The zero-position switch is connected to the controller.

[0007] The positive and beneficial technical effects of this utility model are as follows: the conveying mechanism has precise positioning, eliminates slippage, exerts no force on the chain during operation, ensures the stability of the mushroom bags, is unaffected by environmental dust, and has high reliability.

[0014] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.

[0015] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: servo geared motor; 2: drive sprocket; 3: idler wheel; 4: chain; 5: frame; 6: driven sprocket; 7: tension sprocket; 8: bag pushing device; 801: U-shaped part; 802: bag pushing wheel; 9: through hole; 10: grooved rail; 11: mounting bracket; 12: adjusting elongated hole; 13: pressure roller; 14: U-shaped wheel frame; 15: bolt; 16: bolt connection part; 17: adjusting nut; 18: spring.

[0016] A bag conveying mechanism for an inoculation machine includes a frame 5, a geared motor fixedly installed at one end of the frame, the geared motor being a servo geared motor 1, an active sprocket 2 fixedly connected to the output end of the geared motor, a passive sprocket 6 corresponding to the active sprocket rotatably connected at the other end of the frame, and a sprocket-type idler wheel 3 and a tensioning sprocket 7 rotatably installed on the frame. Figure 5 This is a schematic diagram of the tension sprocket. The tension sprocket is rotatably mounted on the mounting frame 11. The mounting frame 11 has an adjustment elongated hole 12. The mounting frame is bolted to the machine frame through the adjustment elongated hole. Moving the mounting frame along the adjustment elongated hole can adjust the tension of the chain. The chain 4 is wrapped around the drive sprocket, driven sprocket, idler wheel, and tension sprocket. Multiple bag pushing devices 8 are fixedly connected to the chain. The multiple bag pushing devices are evenly distributed along the length of the chain. The pushing device includes a U-shaped part 801 fixedly connected to the chain at the bottom, and a bag pushing wheel 802 is rotatably mounted at the opening of the U-shaped part. A front-to-back groove rail 10 is fixedly mounted on the machine frame. An elongated through hole 9 is opened on the bottom surface of the groove rail. The chain is located below the elongated through hole. When the chain moves, the bag pushing device passes through the through hole. A zero-position switch is fixedly mounted on the machine frame. A sensor that senses the zero-position switch is fixedly mounted on the chain. The zero-position switch is connected to the controller. Using a zero-position switch to correct the servo geared motor for each revolution can eliminate the cumulative error during the rotation of the servo geared motor. Using a zero-position switch to perform zero-position correction of the servo motor rotation angle is a common method to eliminate its cumulative error, which will not be elaborated here. The zero-position switch can be a proximity switch, and the sensor can be fixedly installed on a push bag device.

[0017] As a further step, multiple elastic pressure roller mechanisms are installed on the frame above the trough rail. These elastic pressure roller mechanisms include a U-shaped wheel frame 14 with its opening facing downwards, and a dumbbell-shaped pressure roller 13 rotatably connected to the opening of the U-shaped wheel frame. The axis of the pressure roller is in the left-right direction. At least two bolts 15 are fixedly connected to the U-shaped wheel frame in the up-down direction. The frame has a bolt connection part 16 with a bolt through hole through which the bolt passes. An adjusting nut 17 is screwed onto the upper part of the bolt. A compression spring 18 is threaded through the bolt between the bolt connection part and the U-shaped wheel. When the mushroom bag passes through the trough rail, it contacts the pressure roller. By changing the compression springs of different lengths, different diameter mushroom bags can be accommodated. The elastic pressure roller mechanism is installed above the corresponding work station, such as the punching station, inoculation station, and flattening station. The function of the elastic pressure roller mechanism is to prevent the mushroom bags from moving due to inertia after the servo motor stops when the bags are being transported quickly on the trough, thus preventing misalignment during the operation.

[0018] In this system, when conveying the mushroom bags, the bags are located on the trough rail and move along the rail as the bag-pushing device moves. The position of the bags depends only on the position of the bag-pushing device, which can be controlled by adjusting the rotation angle of the servo reducer motor. In the inoculation machine, the distance between each upstream and downstream station is generally made equal (this distance is also used for the interval between the bag-pushing devices). If the distance between the zero position and the first station is set to be equal to the distance between two adjacent stations, the servo reducer motor can convey the bags to the next station by rotating a fixed angle. The control is very simple and is not prone to errors.

[0019] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
