Description

Technical Field

[0001] The invention relates to a mushroom bag ring capping machine, belonging to the technical field of edible mushroom production. Background Art

[0002] The cultivation process of edible fungi requires many steps, such as putting the mixed culture medium into a stick-shaped bag, then using a ring to cover the mouth of the plastic bag, and then inserting the lid into the ring. The mouth of the plastic bag is sealed by the cooperation of the lid and the ring, and then the mushroom bag is transported to the final outlet, and finally loaded into a basket for transportation.

[0003] The Chinese utility model patent "Automatic ring-capping machine for edible fungi bags" with the authorization announcement number CN206602877U provides an automatic ring-capping machine for edible fungi bags, including a capping mechanism, a shrinking mechanism, a ring-capping mechanism, a main frame, a sub-frame and a sub-frame power unit. The sub-frame is arranged on the main frame, and the sub-frame power unit is arranged on the upper end surface of the main frame. The shrinking mechanism includes a clamping motion unit, a clamping power unit and a shrinking motion unit. The clamping motion unit is used to clamp the bag mouth of the edible fungi bag pushed by the shrinking motion unit, and to open the bag mouth of the edible fungi bag. The automatic ring-capping machine for edible fungi bags can realize the actions of automatic ring feeding, ring-capping and capping, all of which are realized on the principle of mechanical automation, so that the sealing efficiency of edible fungi bags is greatly improved, and a large amount of manpower is reduced, thereby reducing production costs, while ensuring production safety and avoiding the safety hazards of manual ring-capping.

[0004] The Chinese invention patent "Cultivar Bag Covering Machine" with authorization announcement number CN104285676B provides a cultivar bag covering machine that uses machinery to replace manual operation, is easy to operate, and has high production efficiency. The technical solution adopted is that a central shaft is installed in the center of the frame, and a cam divider is installed on the top of the frame. The output of the cam divider is connected to the central shaft. The upper and lower turntables are controlled to rotate and stop by the cam divider, and the movement of the mechanical structure and the action of the cylinder are coordinated to realize the cycle work from the first station to the eighth station, and complete the related actions of putting on the ring, automatically feeding the cultivar bag, automatically closing the cultivar bag, putting on the ring, installing the inner plug, and automatically outputting the cultivar bag. The operation is simple and convenient, with high work efficiency, and is widely used in the installation of cultivar bag covers.

[0005] However, the common feature of the above patents is that the mechanisms of each step of the automatic ring-capping machine are scattered in different fixed positions, and each ring-capping action step of the culture bag must pause between different mechanisms. In addition, a large number of cylinders are used. At the same time, the cylinders correspond one-to-one to each component that needs to be actuated. The structure is relatively complicated, and it is impossible to achieve a good collaborative work effect and it is difficult to increase the operating speed of the equipment.

The cam 338 is a kind of spring which is used to hold the cam 339 in place and is convenient to use for the purpose of loosening the cam 338.

[0099] According to the above description, the structures of the capping claw 33, the collar claw 34 and the bag holding claw 35 are basically the same, and all of them include a base 331, a clamping claw 332, a push plate 334, a push rod 335, a slide rod 336 and a lifting mechanism 339. The base 331 is a main component, and a fixed seat 3311 is fixed to the upper end of the middle part; a guide sleeve 3312 is arranged on the base 331, which can slide up and down outside the column 313; two clamping claws 332 are arranged in the middle of the front end of the base 331 in mirror symmetry; the rear end of the clamping claw 332 is fixed with an opening and closing bearing 3323; the push rod 335 is fixed to the fixed seat 3311 in a horizontal sliding manner along the radial direction of the frame 31; the middle part of the push plate 334 is fixed to one end of the push rod 335 close to the clamping claw 332; slide rods 336 parallel to the push rod 335 are arranged on both sides of the rear end of the push plate 334; the slide rod 336 is slidably arranged on the fixed seat 3311. The opening and closing of the clamping claw 332 can be controlled by pushing the opening and closing bearing 3323 through the push plate 334 .

[0100] The difference between the three lies in that the front end of the clamping claw 332 of the pressing claw 33 is tilted downward, and the end of the front end of the clamping claw 332 is horizontally fixed with an arc-shaped pressing cover opening 3321, and the two pressing cover openings 3321 can be surrounded to form a vertical hollow annular structure; the front end of the clamping claw 332 of the ring claw 34 is fixed with an arc-shaped ring opening 341, and the two arc-shaped ring openings 341 can be surrounded to form a vertical hollow annular structure; the front end of the clamping claw 332 of the bag holding claw 35 is fixed with a semi-cylindrical holding tube 351, and the two holding tubes 351 can be surrounded to form a vertical hollow cylindrical structure. Secondly, in the cover pressing claw 33, the middle of the two clamping claws 332 is rotatably fixed on the base 331 through the same claw rotating shaft 3322; and the two opening and closing bearings 3323 are respectively placed on both sides of the claw rotating shaft 3322, and one end of the retaining spring 333 is fixed to the middle of the clamping claw 332, and the other end is fixed to the base 331; the retaining spring 333 provides elastic force to open the two clamping claws 332; a conical head 3341 is fixed to the middle of the front end of the push plate 334; the opening and closing bearing 3323 is against the outer end surface of the conical head 3341. In this way, in the cover pressing claw 33, the push plate 334 moves forward, which will clamp the cover pressing claw 33, and the retaining spring 333 provides a pulling force to open the cover pressing claw 33. On the other hand, the two clamping claws 332 of the collar claw 34 and the bag holding claw 35 are respectively fixed by two claw rotating shafts 3322, and the distance between the two opening and closing bearings 3323 is smaller than the distance between the two claw rotating shafts 3322; the position retaining spring 333 provides elastic force to make the front ends of the two clamping claws 332 close to each other. In this way, in the collar claw 34 and the bag holding claw 35, the forward movement of the push plate 334 will make the collar claw 34 or the bag holding claw 35 open; the position retaining spring 333 provides a pulling force to clamp the collar claw 34 or the bag holding claw 35.

[0101] In particular, because the bag holding claw 35 is at the lowest position, a lifting mechanism 339 is additionally provided at the lower end of the base 331 of the bag holding claw 35, which mainly plays a protective role.

[0102] Furthermore, the retaining mechanism is a self-locking member 342; the self-locking member 342 includes a horizontal connecting plate 343 and a self-locking block 344 fixed at the lower front end of the connecting plate 343; the self-locking block 344 is located between the two opening and closing bearings 3323; one end of two return springs 338 are respectively fixed on both sides of the push plate 334, and the other ends of the two return springs 338 are respectively fixed on both sides of the base 331; the return spring 338 provides elastic force to keep the push plate 334 away from the clamping claw 332; when the push plate 334 retreats to the rear, the end faces of the two sides of the self-locking block 344 can respectively fit with the two opening and closing bearings 3323, and the front end of the clamping claw 332 is clamped; a horizontal limiting nail 337 is respectively fixed on both sides of the push plate 334; one end of the return spring 338 is fixed on the limiting nail 337.

[0103] According to the above description, due to different usage scenarios, the retaining mechanism of the collar claw 34 and the bag holding claw 35 may also be a self-locking member 342. The self-locking member 342 includes a horizontal connecting plate 343 and a self-locking block 344 fixed to the lower end of the front part of the connecting plate 343; the self-locking block 344 is located between the two opening and closing bearings 3323. Two ends of two return springs 338 are also fixed on both sides of the push plate 334, and the other ends of the two return springs 338 are respectively fixed on both sides of the base 331; the return spring 338 provides elastic force to keep the push plate 334 away from the clamping claw 332.

[0104] When the push rod 335 is pushed forward, the push plate 334 moves forward, driving the self-locking block 344 on the connecting plate 343 to move forward, so that the self-locking block 344 moves away from the closing bearing 3323; then, when the push plate 334 moves forward, it can push the rear end of the clamping claw 332 through the opening and closing bearing 3323. At the same time, because the self-locking block 344 has left between the two opening and closing bearings 3323, the clamping claw 332 can rotate around the claw rotating shaft 3322, and the rear ends of the two clamping claws 332 approach each other while the front ends of the two clamping claws 332 open outward. After the rear end of the push rod 335 is no longer stressed, the push plate 334 begins to retreat under the pulling force of the reset spring 338. During the retreat of the push plate 334, the self-locking block 344 contacts the opening and closing bearing 3323 and pushes the two opening and closing bearings 3323 away from each other, so that the clamping claw 332 opens around the rear end of the claw rotating shaft 3322 and clamps the front end, thereby clamping the collar claw 34 or the bag holding claw 35. After the collar claw 34 or the bag holding claw 35 is clamped, the two outer end faces of the self-locking block 344 are attached to the opening and closing bearing 3323, and the self-locking block 344 is located between the two opening and closing bearings 3323. By limiting the two opening and closing bearings 3323 from getting closer, the front end of the collar claw 34 or the bag holding claw 35 cannot be opened outward, thereby achieving a self-locking effect. The limit pin 337 can provide a simpler and more convenient way to fix the reset spring 338.

[0105] Furthermore, it also includes an anti-error tooth mechanism 37; the anti-error tooth mechanism 37 includes an adjustment disc 371, an adjustment notch 372, an adjustment rack 373, a positioning plate 374, an adjustment bearing 375, a retaining pressure block 376, a limit block 377, a tension spring 378 and an adjustment gear 379; the adjustment disc 371 is fixed to the workbench; the adjustment disc 371 is located above the upper fixed plate 311; the outer circumference of the adjustment disc 371 is provided with at least one vertically penetrating adjustment notch 372, the adjustment An adjustment rack 373 extending along the outer peripheral edge of the adjustment disk 371 is fixed below the notch 372; the adjustment gear 379 is coaxially fixed to the upper end of the tightening spindle 3221; the positioning plate 374 is fixed to the upper end of the adjustment gear 379; the adjustment rack 373 is meshed with the adjustment gear 379; two adjustment bearings 375 are rotatably fixed on the positioning plate 374 corresponding to each adjustment notch 372; the adjustment bearings 375 are arranged on the outer peripheral surface of the adjustment disk 371; the retaining The middle part of the pressure block 376 is rotatably fixed on the adjustment disc 371; one end of the position-keeping pressure block 376 is close to the positioning plate 374, and the outer end can contact the adjustment bearing 375; the other end of the position-keeping pressure block 376 is close to the center of the adjustment disc 371 and is provided with the limit block 377; the limit block 377 is fixed on the adjustment disc 371; the two ends of the tension spring 378 are respectively connected to the limit block 377 and the one end of the position-keeping pressure block 376 away from the adjustment bearing 375 The end is fixed; the tension spring 378 provides elastic force to keep the outer end of the retaining pressure block 376 at the front end of the adjustment notch 372; the outer end edge of the retaining pressure block 376 extends along the outer peripheral edge of the adjustment disk 371; the starting end of the engagement between the adjustment gear 379 and the adjustment rack 373 corresponding to the adjustment notch 372 is provided with a toothed opening; each of the adjustment bearings 375 is divided into two upper and lower bearings, and the two bearings are respectively in contact with the outer end of the retaining pressure block 376 and the outer periphery of the adjustment disk 371.

Its main function is to apply a force to the adjustment bearing 375 on the positioning plate 374 at the position corresponding to the adjustment notch 372 through the outer periphery of the retaining pressure block 376 under the action of the tension spring 378, so that when the bag mouth tightening claw 32 follows the rotation of the mushroom bag transfer table 2, when the adjustment gear 379 enters the adjustment notch 372 and is about to engage with the adjustment rack 373, it is ensured that the meshing position of the adjustment gear 379 and the adjustment rack 373 will not produce misaligned teeth, effectively avoiding the misalignment of the gear and rack positions caused by the misaligned engagement of the gear and rack, and the subsequent possible consequences of the misalignment and failure of the bag mouth tightening claw 32, thereby ensuring working accuracy and efficiency and improving working stability.

[0107] Furthermore, the curved guide rail group 36 includes a guide rail bracket 361 and a bag holding lifting curve 362, a bag holding opening and closing curve 363, a ring claw lifting curve 364, a ring claw opening and closing curve 365, a cover claw lifting curve 366, and a cover claw opening and closing curve 367 coaxially arranged on the outside of the guide rail bracket 361; the guide rail bracket 361 is vertically arranged on the workbench; the upper end surface of the bag holding lifting curve 362, the upper end surface of the ring claw lifting curve 364, and the upper end surface of the cover claw lifting curve 366 are all arranged with high and low fluctuations; the outer periphery of the bag holding opening and closing curve 363, the outer periphery of the ring claw opening and closing curve 365, and the outer periphery of the cover claw opening and closing curve 367 are all arranged with concave and convex fluctuations The bag holding lifting curve 362 and the bag holding opening and closing curve 363 are both arranged on the workbench, and the bag holding opening and closing curve 363 is within the lowest range of the ups and downs bag holding lifting curve 362; the ring claw lifting curve 364 and the ring claw opening and closing curve 365 are both arranged in the middle of the guide rail bracket 361, and the ring claw opening and closing curve 365 is within the lowest range of the ups and downs ring claw lifting curve 364; the cover claw lifting curve 366 and the cover claw opening and closing curve 367 are both arranged in the upper part of the guide rail bracket 361, and the cover claw opening and closing curve 367 is within the lowest range of the ups and downs cover claw lifting curve 366. Each curved guide rail group 36 is mainly used to cooperate with each sleeve ring capping assembly on the mushroom bag transfer table 2 to control the lifting and opening and closing of the corresponding sleeve ring capping assembly. For example, the undulating curved surface at the upper end means that the high part lifts the corresponding sleeve cover assembly, and the low part lowers the height of the corresponding sleeve cover assembly; the undulating curved surface at the outer periphery means that the convex part controls the corresponding sleeve cover assembly to open, and the concave part resets the corresponding sleeve cover assembly under the action of the spring.

[0113] Working principle of the present invention:

[0114] See also Figure 21-23 , Figure 32-Figure 40 The present invention has five working stages when it is working. Figure 21-23 The area1-area5 in the figure represent the area range corresponding to each working stage. In addition, the interval between the area ranges in the figure is only to separate the intervals of two adjacent working stages, and does not mean that the two working stages are separated.

[0115] The first working stage (area1): loading the mushroom bag;

[0116] See also Fig.21 and Fig.32 , the mushroom bag on the feeding conveyor belt 14 enters the mushroom bag transfer table 2 after being guided by the feeding screw 11; at the same time, because the bag holding claw 35 runs at the lowest point of the bag holding lifting curve 362 and the convex point of the bag holding opening and closing curve 363, the bag holding claw 35 is in an open state, so that the mushroom bag can enter the bag holding claw 35 under the push of the material belt plate 23 and be placed on the bag holding bottom plate 352. At the same time, the collar claw 34 is at the lowest point of the collar claw lifting curve 364 and the convex point of the collar claw opening and closing curve 365. After the opened collar claw 34 receives the collar from the feeding device 5, the push rod 335 of the collar claw 34 is separated from the collar claw opening and closing curve 365, and the collar claw 34 clamps the collar and hangs above the bag mouth of the mushroom bag in the bag holding claw 35. In addition, the push rod 335 at the end of the capping claw 33 is separated from the capping claw opening and closing curve 367, and the capping claw 33 changes from a closed state to an open state.

[0117] In particular, the capping claw 33 has not yet come into contact with the capping claw lifting curve 366 at this time, but is pressed against the top of the collar claw 34 through the guide sleeve 3312 under the action of its own gravity, and is driven to rise and fall by the collar claw 34.

[0118] The second working stage (area2): tighten the bag mouth;

[0119] See also Fig. 22 and Fig.33 , Fig.34 , the mushroom bag sealing disk 3 continues to rotate, and the ring claw 34 begins to climb upward along the ring claw lifting curve 364, hiding the ring outside the shrinking groove 3234 of the bag grabbing claw 323 in the tightened state. When the ring claw 34 rises, it lifts the capping claw 33 located above, so that the capping claw 33 enters the high position of the capping claw lifting curve 366; at the same time, the push rod 335 at the end of the bag holding claw 35 breaks away from the bag holding opening and closing curve 363, the bag holding claw 35 clamps the mushroom bag, and then starts to climb along the bag holding lifting curve 362. Then, the adjusting gear 379 on the bag opening tightening claw 32 contacts the first anti-error tooth mechanism 37, driving the tightening main shaft 3221 to rotate, thereby driving the bag grabbing claw 323 to open, and the shrinking claw 324 tightens and presses the bag opening into the gap between the two adjacent bag grabbing claws 323 after opening, so that the bag opening of the mushroom bag is contracted; the tightening main shaft 3221 continues to rotate, the bag grabbing claw 323 begins to tighten and grasp the bag opening, and at the same time the shrinking claw 324 opens outward.

[0120] In particular, after the collar claw 34 climbs up to the highest point along the collar claw lifting curve 364 , the capping claw 33 separates from the collar claw 34 , and begins to contact with the cap claw lifting curve 366 , and is driven to rise and fall by the cap claw lifting curve 366 .

[0121] The third working stage (area3): ringing of the fungus bag;

[0122] See also Fig. 22 and Fig.35 , Fig.36 , the mushroom bag sealing plate 3 continues to rotate. The bag holding claw 35 runs smoothly along the bag holding lifting curve 362; and the ring claw 34 descends from the highest point of the ring claw lifting curve 364, driving the ring to descend and sleeve on the middle outer side of the tightened mushroom bag mouth.

[0123] In particular, after the ring claw 34 has finished descending from the highest point of the ring claw lifting curve 364, it is separated from the ring claw lifting curve 364, and the ring claw 34 begins to rest on the bag holding claw 35 under the action of its own gravity, and is driven to rise and fall by the bag holding claw 35.

[0124] The fourth working stage (area 4): bag opening turning over, grabbing and capping;

[0125] See also Fig.23 and Fig.37 , Fig.38 , the mushroom bag sealing disk 3 continues to rotate. First, the adjustment gear 379 on the bag opening tightening claw 32 contacts the second anti-error tooth mechanism 37, driving the tightening main shaft 3221 to rotate, thereby driving the bag grabbing claw 323 to open to the maximum, and the bag opening is released by the bag grabbing claw 323, so that the bag opening is naturally radially scattered outside the ring; while the shrinking claw 324 remains motionless. The bag holding claw 35 rises again along the bag holding lifting curve 362 to further open the bag opening; then, the capping claw 33 descends from the highest point of the capping claw lifting curve 366 to the lowest point. The closed capping claw 33 is located on the inner side of the bag opening of the mushroom bag. During the descent process, it will press against the bag opening of the mushroom bag to keep the bag opening in an outward-turned state. The mushroom bag sealing plate 3 continues to rotate, the bag holding claw 35 descends along the bag holding lifting curve 362, the capping claw 33 separates from the bag mouth of the mushroom bag, and the brush piece 43 on the bag mouth finishing device 4 contacts the bag mouth of the mushroom bag. The brush piece 43 continuously slaps the bag mouth of the mushroom bag downward, further folding the bag mouth of the mushroom bag outside the collar. At the same time, the capping claw 33 runs to the convex point of the capping claw opening and closing curve 367, and the originally opened capping claw 33 clamps the capping from the feeding device 5 and closes, and hangs above the bag mouth of the mushroom bag in the bag holding claw 35.

[0126] The fifth working stage (area5): capping of mushroom bags and discharge of finished products;

[0127] See also Fig.23 and Fig.39 , Fig.40, the mushroom bag sealing disk 3 continues to rotate. First, the bag holding claw 35 rises again along the bag holding lifting curve 362, and the pressure cap is pressed downward into the upper end of the mushroom bag and the inner side of the collar; then, the push rod 335 of the collar claw 34 begins to contact the ring claw opening and closing curve 365, the collar claw 34 opens, and the collar is released; at the same time, the push rod 335 of the capping claw 33 breaks away from the capping claw opening and closing curve 367, the capping claw 33 opens, and the capping is released. Then, the bag holding claw 35 descends to the lowest point along the bag holding lifting curve 362, and the push rod 335 at the end of the bag holding claw 35 contacts the bag holding opening and closing curve 363, the bag holding claw 35 opens, and the sealed mushroom bag can leave through the discharge conveyor belt 61; at the same time, the adjustment gear 379 on the bag opening tightening claw 32 contacts the third anti-misalignment gear mechanism 37, driving the tightening main shaft 3221 to rotate, so that the bag holding claw 323 shrinks, while the shrinking claw 324 remains open, so that the bag opening tightening claw 32 is reset. At this point, the mushroom bag sealing disk 3 completes a sealing work, and all parts are reset, ready for the next sealing.

[0128] In particular, when the collar claw 34 opens, the collar claw 34 separates from the bag holding claw 35, and starts to contact with the collar claw lifting curve 364 again, and is driven to rise and fall by the collar claw lifting curve 364.

[0129] In particular, when the capping claw 33 is closed, that is, separated from the capping claw lifting curve 366, the capping claw 33 begins to be pressed against the top of the ring claw 34 through the guide sleeve 3312 under the action of its own gravity, and is also driven to rise and fall by the ring claw 34.
