Sponge queuing mechanism of a sponge filling machine

Abstract

This utility model relates to the field of edible fungi production equipment, specifically a sponge queuing mechanism for a sponge-filling machine. It includes a frame, a material hopper, a sponging assembly, a lifting assembly, a sponge-packing assembly, and a sponge-topping assembly. The frame provides stable support for the equipment. The material hopper stores sponges. In the sponging assembly, a geared motor drives a chain to move multiple stirring shafts, employing an alternating "lower engagement - upper engagement" transmission mode. This causes the stirring shafts to rotate in opposite directions, creating a vortex that, in conjunction with the stirring rods, fully loosens the sponges and prevents clumping. The lifting assembly, through the linkage of a drive motor, a reducer, a transmission shaft and transmission gears, and a chain, drives the lifting base to rise and fall stably along the lifting guide rail, achieving precise sponge collection from the sponge-packing cylinder. After resetting, the ejector rod on the ejector frame in the sponge-topping assembly pushes the sponge-topping rod, ejecting any remaining sponges from the sponge-packing cylinder out of the material hopper and preventing blockage.

Description

Technical Field

[0001] This utility model relates to the field of edible fungi production equipment, specifically to a sponge queuing mechanism for a sponge stuffing machine. Background Technology

[0002] In the production of edible fungi, stuffing the mushroom bags with sponges is a crucial step to maintain humidity inside the bags and prevent external contamination. Currently, the main method of manually stuffing the bags and the automated equipment developed by some manufacturers have several problems:

[0003] Hand-stuffed sponge:

[0004] Low efficiency: Manual operation is slow and cannot meet the needs of large-scale production.

[0005] High labor intensity: Prolonged manual operation increases the labor intensity of workers and is prone to occupational diseases.

[0006] Susceptible to infection: External contaminants can be easily introduced during manual handling, increasing the risk of infection of the spawn bags.

[0007] Existing sponge plugging equipment:

[0008] Queuing method for mixing conveyor belts:

[0009] Principle: After the sponge material is loosened by a stirring device, it is transported and queued by a conveyor belt.

[0010] Disadvantages: Due to the compressibility of the sponge, the sponge at the front end will be squeezed under the friction of the conveyor belt, making it difficult to accurately control the queuing distance. This can lead to eccentricity when picking up the sponge, causing it to easily fall off during movement, or even fail to be picked up at all, resulting in low success rate of sponge insertion and sponge scattered all over the ground.

[0011] Improve the queuing system for delivery:

[0012] Principle: A lifting device is used instead of a traditional conveyor belt to improve the stability of the sponge queue.

[0013] Disadvantages: Although stability is improved, the use of a conveyor belt still presents the drawbacks of the aforementioned mixing conveyor belt queuing method. Furthermore, the stability of this improvement method remains poor, failing to gain acceptance from mushroom farmers and hindering its widespread application.

[0014] Problems with existing cotton stuffing machines:

[0015] Clogging problem: During operation, existing sponge packing machines may experience clogging of the packing cylinder due to uneven distribution of sponge material or unreasonable equipment design, which may prevent the sponge from being picked up normally and affect production efficiency.

[0054] Provides fundamental support for the entire device, ensuring the stable operation of each component.

[0055] Material bucket 2

[0056] It is fixedly installed on the frame 1 and is used to store the sponge material to be processed. The design of the material tank 2 ensures that the sponge can smoothly enter the subsequent processing steps.

[0057] cotton churning assembly

[0058] It includes a geared motor 3, a drive wheel 10, a sprocket 9, a stirring shaft 7, and a chain 11. The geared motor 3 drives multiple stirring shafts 7 to rotate via the chain 11, and each stirring shaft 7 is equipped with several stirring rods 8.

[0059] Working principle: The geared motor 3 drives the chain 11 through the drive wheel 10. The chain 11 drives the sprockets 9 on each stirring shaft 7 to rotate, thereby causing the stirring shaft 7 to rotate. The stirring rods 8 are evenly distributed along the length of the stirring shaft 7 to ensure that the sponge material is fully stirred and loosened, preventing clumping and facilitating subsequent operations.

[0060] Lifting components

[0061] It includes a drive motor 4, a reducer 5, a drive shaft 13, a transmission gear 14, a chain 2 12, and a lifting guide rail 17. The drive motor 4 drives the drive shaft 13 to rotate through the reducer 5, and the transmission gear 14 on the drive shaft 13 drives the cotton sleeve 6 to move up and down through the chain 2 12.

[0062] Working principle: After the drive motor 4 starts, it is reduced in speed and increased in torque by the reducer 5, which drives the transmission shaft 13 to rotate. The transmission gear 14 on the transmission shaft 13 drives another transmission gear 14 meshing with it to rotate through the chain 2 12, thereby realizing the up and down movement of the chain 2 12. The lifting base 16, which is fixedly connected to the chain 2 12, moves up and down accordingly. The lifting base 16 is slidably installed with the lifting guide rail 17 through the slider, which ensures the stability of the lifting base 16 driving the cotton sleeve 6 to complete the lifting action.

[0063] Cotton-covered components

The lifting base 16 is slidably connected to the lifting guide rail 17 via a slider, and the chain 12 is fixedly connected to the lifting base 16 to realize up and down movement.

[0065] Working principle: When the lifting base 16 rises, the cotton sleeve 6 takes out a certain amount of sponge from the material barrel 2 and lifts it to the predetermined position to prepare for the next operation. The sponge in the cotton sleeve 6 is grabbed by negative pressure adsorption or mechanical extrusion.

[0066] Top Cotton Components

[0067] It includes an ejector frame 19 and a top cotton rod 21. The ejector frame 19 is fixedly installed at the bottom of the frame 1, perpendicular to the bottom of the lifting base 16. The top cotton rod 21 is slidably installed inside the cotton sleeve 6, and its bottom end passes through the lifting base 16.

[0068] Working principle: The ejector rod 20 on the ejector frame 19 is adapted to the bottom end of the cotton-push rod 21. When the cotton sleeve 6 descends to the bottom of the frame 1, the ejector rod 20 pushes the cotton-push rod 21 vertically, pushing the sponge remaining in the cotton sleeve 6 out to the material bucket 2.

The two ends of the chain 11 are respectively sleeved on the drive wheel 10 of the reduction motor 3 and the sprocket 9 of the outermost stirring shaft 7. The chain 11 on the two middle sprockets 9 adopts the alternating transmission mode of "lower meshing-upper meshing" to drive the stirring shaft 7 in the middle position to rotate in the opposite direction, forming a vortex loosening effect.

[0071] Protective cover 22: A protective cover 22 is fixedly installed on the side of the material bucket 2, covering the sprocket 9 and chain 11, protecting the key components from the influence of the external environment and extending their service life.

[0072] Guide frame 15 and transmission gear 14: The guide frame 15 is installed perpendicularly to the drive shaft 13. Two transmission gears 14 are respectively installed on the drive shaft 13 and the guide frame 15. Chain 2 12 is sleeved on it to ensure that chain 2 12 runs smoothly and provides stable lifting power.

[0073] The ejector rod 20 and the cotton-push rod 21 are matched: The ejector frame 19 is equipped with multiple ejector rods 20, which are precisely matched with the bottom end of the cotton-push rod 21 to ensure that each ejection action is accurate and error-free, and to avoid jamming or misoperation.

[0074] Detailed Workflow Summary

[0075] Preprocessing stage:

[0076] The sponge material is placed into material bucket 2, ready to enter the cotton mixing process.

[0077] Blending stage:

[0078] When the geared motor 3 starts, it drives multiple stirring shafts 7 to rotate via chain 11. The stirring rod 8 fully loosens the sponge material to prevent clumping.

[0079] Lifting preparation phase:

[0080] The drive motor 4 starts and drives the transmission shaft 13 to rotate through the reducer 5. The transmission gear 14 drives the lifting base 16 and the cotton sleeve 6 on it to rise through the chain 2 12, and takes out an appropriate amount of sponge from the material bucket 2.

[0081] Cotton application stage:

[0082] The cotton sleeve 6 rises to the predetermined height, awaiting further operation, and the sponge inside the cotton sleeve 6 is grabbed by negative pressure adsorption or mechanical squeezing.

[0083] Reset phase:

[0084] After one round of stuffing, the lifting base 16 descends back to its initial position, ready for the next round of operation.

[0085] Top-coat stage:

[0086] As the lifting base 16 descends, the ejector rod 20 on the ejector frame 19 pushes the cotton ejector rod 21 upward, pushing out the sponge remaining in the cotton sleeve 6 to prevent the cotton sleeve 6 from becoming clogged.
