Description

Technical Field

[0001] This utility model relates to the field of inner bacteria bag opening technology, specifically to a device for opening inner bacteria bags. Background Technology

[0002] Inner bags, also known as mushroom bags, are specialized containers used in edible mushroom cultivation to hold substrate and promote mycelial growth. They are an indispensable key tool in the modern edible mushroom industry. Their core function is to provide a suitable growth environment for fungi by controlling conditions such as temperature, humidity, and ventilation, thereby achieving efficient mycelial cultivation and fruiting body formation.

[0003] Inner bags are typically made of polypropylene or polyethylene plastic. The inoculated bag is called a spawn bag, and its management includes steps such as light protection, humidity control, ventilation, and oxygenation to ensure normal mycelial growth and prevent contamination by other microorganisms. Spawn bags are widely used for the cultivation of various edible fungi such as shiitake, oyster, and king oyster mushrooms. They are suitable for both industrial and small-scale farmer production and serve as a crucial link between the spawn and the final product.

[0004] Currently, the opening of the inner bag is usually opened manually by workers. For example, workers need to separate individual bags from the standardized bag rolls one by one, complete the bag separation with a mechanical cutting device, and then manually open the opening of the inner bag.

[0058] Braking assembly 2 includes a braking mechanism and a tensioning roller 204. The inner mushroom bag 6 is wound and tightened and fixed on the tensioning roller 204. That is, the inner mushroom bag 6 is wound into a roll and then fitted onto the tensioning roller 204, and is tightened and fixed by the tensioning roller 204. When the diffuse reflection fiber optic sensor 102 detects the sealing point of the inner mushroom bag 6, the braking mechanism is activated to lock the tensioning roller 204.

Specifically, the third mounting plate 201 is fixedly installed, the brake disc 203 is coaxially and fixedly connected to the tension roller 204, and the tension roller 204 is rotatably mounted on the third mounting plate 201 via a bearing. One end of the brake caliper 205 is hinged to the third mounting plate 201, and the other end is driven by the brake cylinder 202 to move closer to or away from the brake disc 203. The basic working principle of the braking mechanism is as follows: when the diffuse reflection fiber optic sensor 102 detects the sealing point of the inner bacterial bag 6, the piston rod of the brake cylinder 202 extends, pushing the other end of the brake caliper 205 to press against the circumferential surface of the brake disc 203, using friction to stop the brake disc 203 from rotating.

The motor 402 is fixedly mounted on the sixth mounting plate 401, and the rubber-coated roller 403 is coaxially fixed with the output shaft of the motor 402, so that the rubber-coated roller 403 can be driven to rotate by the motor 402. The pressure roller 406 is arranged parallel to one side of the rubber-coated roller 403 and is pressed onto the rubber-coated roller 403 by an elastic swing mechanism to clamp the inner bacterial bag 6. Specifically, the inner bacterial bag 6 is manually placed between the rubber-coated roller 403 and the pressure roller 406, so that the rubber-coated roller 403 and the pressure roller 406 can clamp the inner bacterial bag 6 under the action of the elastic swing mechanism.

[0064] The elastic swing mechanism includes a swing frame 404, a fixed shaft 405, and an elastic element 407.

The pipes include a first pipe and a second pipe. The fan 301 and the negative pressure shut-off valve 302 are connected through the first pipe. The negative pressure shut-off valve 302 is connected to the first suction cup assembly 503 and the second suction cup assembly 504 through two second pipes respectively.

[0066] The first suction cup assembly 503 includes a first suction cup 5031, a bag pressing component 5032, and a first guide rail 5033. The first suction cup 5031 is slidably connected to the first guide rail 5033 and the second mounting base 508. The second suction cup assembly 504 includes a second suction cup 5041 and a second guide rail 5042. The second suction cup 5041 is slidably connected to the first mounting base 507 via the second guide rail 5042.

[0067] The bag opening assembly 5 also includes a seventh mounting plate 501 and an eighth mounting plate 502 mounted on the bottom of the seventh mounting plate 501; a sixth mounting plate 401 is fixed to the upper surface of the seventh mounting plate 501; a first suction cup assembly 503 and a second suction cup assembly 504 are slidably connected to the eighth mounting plate 502 via a third guide rail 509.

[0068] The drive mechanism includes a bag-opening cylinder 505, a timing belt 506, a first mounting base 507, and a second mounting base 508. The bag-opening cylinder 505 is mounted on one side of the eighth mounting plate 502, and the timing belt 506 is disposed on the other side of the eighth mounting plate 502 via two timing pulleys.

The timing belt 506 has a lower straight portion 5061 and an upper straight portion 5062 arranged parallel to each other. The first mounting base 507 and the second mounting base 508 are respectively fixed on the lower straight portion 5061 and the upper straight portion 5062.

[0069] The third guide rail 509 has two sliders, which are fixedly connected to the first mounting base 507 and the second mounting base 508 by bolts respectively.

[0070] The bag feeding assembly 7 is used to transfer the inner bacteria bag 6; the bag feeding assembly 7 includes a bag feeding cylinder 701 and a bag feeding rod 702, and the bag feeding rod 702 is fixedly connected to the piston rod of the bag feeding cylinder 701.

[0071] The first mounting plate 101, the second mounting plate 107, the seventh mounting plate 501, the third mounting plate 201, the fourth mounting plate 303, and the fifth mounting plate 304 in the above scheme can all be fixed to the frame of the entire device by bolts, thereby achieving their fixed position.

[0072] The working principle of the above-mentioned inner mushroom bag opening device is as follows: the worker places a roll of inner mushroom bag 6 on the tension roller 204 of the brake assembly 2, and uses the tension roller 204 to tighten and fix the inner mushroom bag 6. Then, the worker manually pulls the inner mushroom bag 6 to pass through the first guide roller 103 and the second guide roller 105. Finally, the inner mushroom bag 6 passes through and is clamped between the rubber coating roller 403 and the pressure roller 406 in the bag cutting assembly 4.

[0073] Start the motor 402 to drive the rubber-coating roller 403 to rotate. Since the inner bacterial bag 6 is pressed tightly onto the rubber-coating roller 403 by the pressure roller 406, the rotation of the rubber-coating roller 403 will cause the inner bacterial bag 6 to be slowly removed. When the diffuse reflection fiber optic sensor 102 detects the sealing point of the inner bacterial bag 6, the braking mechanism is activated to lock the tension roller 204, and the bag removal is completed at this time.

[0074] The extension action of the bag-opening cylinder 505 in the bag-opening assembly 5 drives the synchronous belt 506 to rotate in the forward direction. The synchronous belt 506 drives the first mounting base 507 and the second mounting base 508 to move towards the center synchronously, thereby causing the first suction cup assembly 503 and the second suction cup assembly 504 to move towards the center synchronously and clamp the inner bacteria bag 6. At the same time, the bag-pressing component 5032 on the first suction cup assembly 503 presses the inner bacteria bag 6 firmly onto the sixth mounting plate 401. The bag-cutting cylinder 408 is activated, driving the bag-cutting knife 409 to cut the inner bacteria bag 6 pressed onto the sixth mounting plate 401.

[0075] When the fan 301 in the negative pressure generating component 3 starts to generate negative pressure, the negative pressure shut-off valve 302 is activated to open the valve, so that the first suction cup 5031 and the second suction cup 5041 generate negative pressure, thereby allowing the left and right sides of the inner bacteria bag 6 to be firmly attached to the first suction cup 5031 and the second suction cup 5041 respectively.

[0076] The retraction action of the bag-opening cylinder 505 drives the synchronous belt 506 to rotate in the opposite direction, so that the first suction cup assembly 503 and the second suction cup assembly 504 move away synchronously, thereby using the first suction cup 5031 and the second suction cup 5041 to open the inner bag and complete the bag opening.

[0077] The bag feeding cylinder 701 in the bag feeding assembly 7 is activated to push the bag feeding rod 702 to move. The bag feeding rod 702 pushes the first suction cup assembly 503 and the second suction cup assembly 504 to move synchronously along the first guide rail 5033 and the second guide rail 5042, respectively, to complete the bag feeding.
