Description

Technical Field

[0001] This invention relates to the field of mushroom stick binding machine technology, specifically a mushroom stick binding machine based on a cam structure. Background Technology

[0002] In the cultivation of edible fungi, tying the opening of the mushroom bag is one of the key steps, and its efficiency and quality directly affect the cultivation results. Currently, the traditional manual method of tying the opening of mushroom bags requires multiple steps, including clamping the rope end, wrapping the rope, tightening, and cutting. Tying a single mushroom bag is time-consuming and cannot meet the production needs of large-scale cultivation.

[0003] While some existing technologies attempt to replace manual labor with mechanized devices, they still have significant drawbacks: for example, the multi-step operations such as rope clamping, rope winding, tightening, and cutting require complex electronic control systems, which are costly and difficult to maintain.

[0094] When the rope binding finger 20101 rotates to bind the first turn, the cam rotation motor 207 drives the cam mounting disk 20102 to rotate, which in turn drives the hook finger moving cam 20103, the hook finger rotating cam 20104, the rope cutting cam 20105 and the rope clamping head cam 20106 to rotate.

[0095] When rotation begins, the hook moving cam 20103 abuts against the first guide wheel 203011, causing the hook moving guide rod 203013 of the hook moving mechanism assembly 20301 to move downward. At this time, the first return spring 203016 gradually enters a compressed state, causing the lifting seat 20302 and the hook rotating mechanism assembly 20303 to move downward as a whole until the hook 20305 at the bottom of the hook rotating mechanism assembly 20303 moves to the lower stop point.

[0096] When the rope binding finger 20101 rotates clockwise to 190 degrees, the rope pulling cylinder 301 extends, causing the rope pulling finger mechanism assembly 302 to be pushed forward to the maximum stroke of the rope pulling cylinder 301.

[0097] When the rope binding finger 20101 rotates clockwise to 360 degrees, the rope binding origin photoelectric switch 401 on the rope return mechanism 4 detects a signal. Under the action of the hook finger moving cam 20103, the first reset spring 203016 drives the hook finger moving guide rod 203013 to move upward, so that the lifting seat 20302 and the hook finger rotating mechanism assembly 20303 move upward as a whole, and the hook finger 20305 returns to the origin.

[0098] The output end of the rocker cylinder 402 on the rope return mechanism 4 extends, causing the rotating plate 409 to rotate around the pin 408 until the rope pressing rod 403 presses the binding rope 6 onto the rubber rod 404. The rope return motor 405 connected to the rubber rod 404 rotates clockwise to release the rope.

[0099] When the rope binding finger 20101 is rotating clockwise for the second turn, when the rope binding finger 20101 rotates clockwise to approximately 360+100 degrees, the output end of the rope clamping finger cylinder 30201 on the rope tensioning mechanism 3 retracts, causing the rack 30202 to drive the gear 30203 to rotate. The gear 30203 drives the rope clamping finger 30207 to close through the horizontal shaft 30205, thus clamping the rope end with the rope clamping finger 30207.

[0100] When the binding finger 20101 is rotating clockwise for the third turn, and the binding finger 20101 is rotating clockwise to 360+360+60 degrees, the binding rope 6 will exert a pulling force on the rope head clamped by the rope head actuator 20401. At this time, under the action of the rope head cam 20106 against the third guide wheel 204022, the rope head moving guide rod 20402 pushes the rope head actuator 20401 to move downward, and the rope head moving guide rod assembly 20402 makes the rope head disengage from the rope head actuator 20401.

[0101] At this moment, the rope clamping head actuator 20401 falls into the slot at the front end of the rope tensioning mechanism 3, and the rope head is pulled out of the rope clamping head actuator 20401 under the action of the tension of the binding rope 6 and the force of the rope clamping finger 30207.

[0102] As the binding finger 20101 continues to rotate, when it rotates clockwise to the notch directly below the hook 20305, the hook moving cam 20103, against the first guide wheel 203011, causes the hook moving guide rod 203013 of the hook moving mechanism assembly 20301 to move downwards. The lifting seat 20302 and the hook rotating mechanism assembly 20303 move downwards as a whole, and the hook 20305 at the bottom of the hook rotating mechanism assembly 20303 moves to its lower stop point, allowing the binding rope 6 to enter the hook 20305, and the binding finger 20101 stops rotating. Simultaneously, the return rope motor 405 stops rotating.

[0103] When the binding finger 20101 reverses and retracts the binding rope 6 for the first turn, the binding finger 20101 rotates counterclockwise. When the binding finger 20101 rotates 60 degrees counterclockwise, the hook rotating cam 20104 acts on the second guide wheel 203031 on the hook rotating mechanism assembly 20303. The hook rotating guide rod 203033 of the hook rotating mechanism assembly 20303 rotates slowly according to the displacement angle law of the hook rotating cam 20104, causing the hook 20305 to disengage the outer knot of the binding rope 6.

[0104] When the rope binding finger 20101 rotates 120 degrees counterclockwise, the rope binding finger 20101 stops rotating, the output end of the rocker arm cylinder 402 on the return rope motor 405 retracts, causing the rope pressing rod 403 to leave the rubber rod 404, the output end of the rope pulling cylinder 301 on the rope tightening mechanism 3 retracts, thereby tightening the rope knot, and the rope pulling finger seat 30204 on the rope pulling seat 303 resets;

[0105] The hook-rotating cam 20104 acts on the hook-rotating mechanism assembly 20303. According to the displacement angle law of the hook-rotating cam 20104, and under the elastic force of the second reset spring 203036, the hook-rotating guide rod 203033 moves upward to make the hook 20305 rotate back to its original position.

[0106] The output end of the rocker arm cylinder 402 extends, causing the rope pressing rod 403 to press the binding rope 6 tightly onto the rubber rod 404.

[0107] When the rope binding finger 20101 continues to reverse to 200 degrees, the binding rope 6 just enters the rope clamping head actuator 20401. The rope binding finger 20101 stops, the rope clamping head cam 20106 acts on the third guide wheel 204022, and under the action of the elastic force of the third return spring 204024 on the rope clamping head moving guide rod 20402, the rope clamping head actuator 20401 connected to the bottom of the rope clamping head moving guide rod 20402 moves upward and retracts, clamping the end of the binding rope 6.

[0108] When the rope binding finger 20101 continues to reverse to 260 degrees, the rope cutting cam 20105 acts on the fourth guide wheel 204032 at the top of the rope cutting moving guide rod 20403, the rope cutting moving guide rod 20403 moves down, the fourth return spring 204034 is gradually compressed, causing the rope cutting moving guide rod 20403 to extend and cut the binding rope 6.

[0109] At the same time, the hook rotating cam 20104 acts on the hook rotating mechanism assembly 20303, and the hook rotating guide rod 203033 of the hook rotating mechanism assembly 20303 acts on the hook 20305 through the hook connecting rod 20304, causing the hook 20305 to rotate counterclockwise, causing the inner loop of the binding rope 6 to disengage.

[0110] At the same time, the output end of the rope clamping finger cylinder 30201 extends, causing the rope clamping finger 30207 on the rope tensioning mechanism 3 to loosen the rope end.

[0111] When the binding rope finger 20101 is reversed to 300 degrees, the piston rod 20202 of the claw-shaped mechanism cylinder 205 retracts, causing the gripper 20209 to loosen the opening of the mushroom bag of the mushroom stick 5. Under the action of the motion law of the hook finger moving cam 20103 and the elastic force of the first return spring 203016, the hook finger moving mechanism assembly 20301 moves upward, causing the lifting seat 20302 and the hook finger rotating mechanism assembly 20303 to move upward back to the initial position as a whole.

[0112] When the rope-tying finger 20101 reverses the second and third turns of the rope, and the rope-tying finger 20101 begins to rotate counterclockwise 230+360 degrees back to its initial position, the rope-tying origin photoelectric switch 401 on the rope-feeding mechanism 4 detects a signal. Under the action of the hook-finger moving mechanism assembly 20301 and the spring force of the hook-finger moving cam 20103 and the first reset spring 203016, the lifting seat 20302 and the hook-finger rotating mechanism assembly 20303 move upward as a whole. The hook 20305 rotates back to the origin, the rope-tying finger 20101 stops rotating, the output end of the rocker arm cylinder 402 on the rope-feeding mechanism 4 extends, and the rope-pressing rod 403 presses the binding rope 6 tightly onto the rubber rod 404. The rubber rod 404 of the rope-feeding motor 405 rotates counterclockwise to retract the excess binding rope 6.

[0113] When the tension detection inductor 406 on the return rope mechanism 4 detects that the retracted binding rope 6 has been tightened, the output end of the rocker arm cylinder 402 retracts, and the return rope motor 405 stops the rotation of the glue rod 404, thus completing one binding operation of the mushroom bag opening of the mushroom stick 5.

[0114] Repeat the above steps until the openings of all mushroom bags 5 are tied.

[0115] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
