Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bulk material, sterilization and bagging process, and fermentation material bagging equipment, and in particular to an automatic mouth-holding and flat-mouth device for bagging cooked and fermented materials for edible fungi. Background Technology
[0002] Many edible mushroom spawn bags currently use the pinch-and-insert-stick packaging method, primarily for varieties such as black fungus, shiitake mushrooms (short-pack spawn), and nameko mushrooms. This method is necessary for many varieties when preparing primary spawn. The advantage of this approach is that it eliminates the need for traditional methods like using rings or cotton plugs. Instead, the excess plastic bag at the top of the spawn bag is pinched closed and then inserted into the naturally formed holes created during spawn packaging. A plastic stick is then inserted to seal the holes and provide shaping. This method is simple, reasonable, low-cost, and results in rapid germination and consistent mycelial age. It is widely used in the edible mushroom industry. However, this method is primarily used for raw material cultivation of the spawn bag substrate (edible mushroom substrate consists of a synthetic culture medium composed of sawdust, wheat bran, soybean meal, gypsum, lime, etc.).
[0003] Because this process uses a special technique of sterilizing the edible mushroom substrate (culture medium) before bagging, the spawn is simultaneously implanted while the substrate is being bagged. Unlike the traditional process, which requires inserting plastic rods, sterilizing, cooling, and then planting, this process eliminates the need for plastic rods during the production of mushroom bags. The existing plastic rods in mushroom bags serve the following purposes: 1. Waterproofing (the mushroom bags need to be inverted before being steamed to prevent condensation from entering the bag and causing excessive moisture content in the culture medium and excessive humidity at the bag opening, leading to contamination); 2. Preventing unfiltered, bacteria-laden air from entering the bag after sterilization and causing contamination; 3. Better shaping the pores inside the bag, creating a sufficiently regular inoculation space to facilitate the implantation of spawn after cooling. Additionally, this process ensures a tighter seal at the bag opening, a smoother surface, and a more regular appearance, which helps control contamination and facilitates the sale of the mushroom bags.
[0004] Therefore, when using the bulk material sterilization process, it is necessary to solve the problem of ensuring the overall flatness of the substrate surface of the mushroom bags without the existing plastic rods (when the existing mushroom bags are fitted with plastic rods, the next work station has a process of compacting and flattening the substrate surface of the mushroom bags, and the plastic rods support it so that the substrate surface does not fall apart). Utility Model Content
[0005] The main purpose of this utility model is to provide an automatic mouth-holding and leveling device for bagging cooked and fermented materials for edible mushroom bags, so as to solve the problem of ensuring the overall flatness of the material surface of the mushroom bag under the condition that there are no existing plastic rods to tighten it.
[0006] To achieve the above object, the utility model provides the following technical scheme:
[0007] The automatic mouth holding and flattening device for edible mushroom nest mouth machine mature material and fermentation material bagging includes a first reciprocating mechanism, the output end of the first reciprocating mechanism is fixedly connected with a plug rod, an outer sleeve is fixedly connected to the bottom end of the output end of the first reciprocating mechanism, a chain wheel is arranged at the top end of the outer sleeve, a transmission plate is arranged in the middle part of the outer sleeve, a mechanical claw fixed plate is fixedly connected to the bottom end of the outer sleeve, a plurality of springs are fixedly connected to the top end of the mechanical claw fixed plate, a mechanical claw movable plate is fixedly connected to the top end of the plurality of springs, a plurality of bearings are arranged between the mechanical claw movable plate and the transmission plate, a mechanical claw is arranged on the side surface of the mechanical claw fixed plate, a second reciprocating mechanism is fixedly connected to the other side of the bottom end of the transmission plate, a first rubber pad is arranged on the side surface of the plug rod, and a plurality of second rubber pads are arranged at the bottom end of the mechanical claw.
[0008] Preferably, the automatic mouth holding and flattening device includes a first reciprocating mechanism, the output end of the first reciprocating mechanism is fixedly connected with a plug rod, an outer sleeve is fixedly connected to the bottom end of the output end of the first reciprocating mechanism, a chain wheel is arranged at the top end of the outer sleeve, a transmission plate is arranged in the middle part of the outer sleeve, a mechanical claw fixed plate is fixedly connected to the bottom end of the outer sleeve, a plurality of springs are fixedly connected to the top end of the mechanical claw fixed plate, a mechanical claw movable plate is fixedly connected to the top end of the plurality of springs, a plurality of bearings are arranged between the mechanical claw movable plate and the transmission plate, a mechanical claw is arranged on the side surface of the mechanical claw fixed plate, a second reciprocating mechanism is fixedly connected to the other side of the bottom end of the transmission plate, a clamping groove is formed in the middle part of the plug rod, a pressing plate is sleeved in the clamping groove, a first rubber pad is arranged on the side surface of the plug rod, and a plurality of second rubber pads are arranged at the bottom end of the mechanical claw.
[0009] Preferably, the first reciprocating mechanism and the second reciprocating mechanism are respectively provided with a first servo motor and a second servo motor or a first air cylinder and a second air cylinder.
[0010] Preferably, when the second reciprocating mechanism moves downward, the mechanical claw movable plate is driven to be close to the mechanical claw fixed plate and the springs are compressed at the same time, so that the bottom ends of the plurality of mechanical claws are close to each other, and when the second reciprocating mechanism moves upward, the mechanical claw movable plate is driven to be away from the mechanical claw fixed plate, and the springs are restored to the original position, so that the bottom ends of the plurality of mechanical claws are away from each other.
[0011] Preferably, the chain wheel drives the outer sleeve to rotate, and the outer sleeve drives the mechanical claw fixed plate to rotate.
[0012] In the utility model, although the auxiliary effect of the plastic plug rod in the prior art is not needed, the plug rod of the machine itself and reasonable action can still achieve the process purpose of making the surface of the mushroom bag flat and the hole in the middle of the mushroom bag not collapsed without a plastic rod.
[0013] II. In this utility model, the first reciprocating mechanism drives the insertion rod to move downwards, initially reaching a position approximately 2-3 cm above the open circumferential surface of the mushroom bag. Then, the second reciprocating mechanism moves downwards, causing the moving plate of the mechanical claw to approach the fixed plate of the mechanical claw, simultaneously compressing the spring and causing the bottom ends of multiple mechanical claws to move closer together. Multiple second rubber pads firmly grip and tighten the plastic bag at the front end of the insertion rod. After tightening the plastic bag, the second reciprocating mechanism immediately moves upwards, causing the mechanical claws to immediately open and return to their initial position. Then, the first reciprocating mechanism continues its downward movement, inserting the tightened plastic bag into the holes of the mushroom bag. The insertion depth is 4-5cm. Then, the first reciprocating mechanism continues to drive the insertion rod to continue downward. At this time, the pressure plate set on the insertion rod is driven to move downward. When the pressure plate is clamped by the slot plane set on the insertion rod, it presses down and contacts the surface of the mushroom bag, flattening the surface of the mushroom bag. After the pressure plate completes the flattening action, the first reciprocating mechanism drives the insertion rod to return to the initial position. The above actions are repeated. In this way, the problem of the overall neatness of the mushroom bag can be solved even without the existing plastic rod, because when the pressure plate presses down on the surface of the material, the mechanical claw insertion rod is programmed to be 4-5cm inside the hole, which just plays a role in cooperating with the force of the pressure plate, so that the surface of the mushroom bag is flat and does not collapse.
