Description

Technical Field

[0001] The utility model relates to the field of edible fungus production equipment, in particular to edible fungus bag production equipment with a three-station single-piece bag feeding device. Background Art

[0002] In the edible fungus industry, traditional mushroom bag production equipment mostly uses double-station bagging machines, and mainly uses roll-bag feeding. This feeding method means that only two bags of mushroom bags can be produced in one cycle, and the production efficiency is relatively low. With the continuous changes in the production environment and the growing market demand, this production efficiency can no longer meet the needs of modern production lines.

[0003] In order to meet this challenge and improve production efficiency, the industry urgently needs a new and more efficient bagging machine that can produce three bags of mushrooms in one cycle, thereby significantly improving production efficiency.

[0004] However, to cooperate with this new three-station high-speed bagging machine, a corresponding bag feeding device must be used. The existing double-station bagging machines and their matching roll bag feeding devices on the market cannot be directly applied to the new generation of three-station high-speed bagging machines due to structural design and functional limitations.

[0043] The bag opening rotating assembly 7 is used to open the bag opening on the bag placing tray assembly 10 and deliver it to a designated position;

[0044] The suction switching valve 4 is used to control the generation and cut-off of negative pressure of the bag suction moving component 3 and the bag opening rotating component 7;

[0045] A fan for generating negative pressure;

[0046] The box body 1 is used as an equipment frame 18 for installing the bag placing component 2, the bag suction moving component 3, the bag opening rotating component 7, the air suction switching valve 4 and the fan.

[0047] The preferred solution of the mushroom bag production equipment of the above-mentioned three-station single-piece bag feeding device for edible mushroom bags is as follows: the bag placing component 2 also includes a bag lifting mechanism and a bag pushing mechanism, the bag placing box component 8 of group A and the bag placing box component 9 of group B are respectively located on the left and right sides of the bottom of the box body 1, the bag placing tray 19 component 10 is located between the bag placing box component 8 of group A and the bag placing box component 9 of group B, the bag lifting mechanism includes a frame 11, a bag sensor switch 13, a bag lifting motor 17, a bag lifting gear, a bag lifting rack 15, a bag lifting carriage 12 and a bag blowing member 14, and the bag lifting motor 17 is fixedly installed at the bottom of the frame 11. The bag lifting carriage 12 is located above the frame 11, and the bag lifting rack 15 is located at the bottom of the bag lifting carriage 12 and penetrates the frame 11.

The frame 11 is provided with a bag lifting guide rail 16, which is adapted to the bag lifting carriage 12 and is located at the corner of the bag lifting carriage 12;

[0048] Bag placing assembly 2: The bag placing box assembly 8 of group A and the bag placing box assembly 9 of group B are respectively located on the left and right sides of the bottom of the box body 1, and are used to store the mushroom bags to be processed. The bag placing tray assembly 10 is located between the two groups of bag placing box assemblies, and temporarily stores the mushroom bags taken out from the bag placing box assemblies;

[0049] Manually place the bundle of single mushroom bags neatly into the bag placing box assembly 8 of group A or the bag placing box assembly 9 of group B, and then place the entire bag placing box assembly 8 of group A or the bag placing box assembly 9 into the corresponding position slots A1, A2, A3, B1, B2, B3. The bag suction moving assembly 3 of the equipment is running, and the bag transfer suction box 28 at the A, B, and C positions respectively moves to the left to the corresponding A1, A2, and A3 positions, and descends to suck up a bag and put it into the corresponding bag placing tray 19. Each time a bag is taken, as the height of the bag decreases, after the bag sensing switch 13 does not detect it, the bag lifting motor 17 runs, and through the transmission of the bag lifting gear and the bag lifting rack 15, under the guidance of the bag lifting guide rail 16, the bag lifting carriage 12 is raised, thereby pushing the bag up. When the bag is detected by the detection switch again, the motor stops. At this time, the bag transfer suction box 28 continuously sucks the bag until the bag lifting carriage 12 rises to the highest point. When the detection switch still cannot detect the bag, it means that there is no bag in the box. At this time, no matter which of the three bag placing boxes prompts that there is no bag first, the device will alarm to remind the worker to replenish the bag. At this time, the bag transfer suction box 28 will move to the bag placing box assembly on the other side to suck the bag, and will not be affected by the worker placing the bag on the bag-deficient side.

[0050] The preferred scheme of the mushroom bag production equipment of the above-mentioned three-station single-piece bag feeding device for edible mushroom bags is as follows: the bag placing tray assembly 10 includes an equipment frame 18, a bag placing tray 19, a bag pushing tail cylinder, a bag pushing tail plate 20, a fixed bearing block 21 and a bag pressing tail block 22, the bag placing tray 19 is arranged on the top of the equipment frame 18, the bag pushing tail plate 20 is slidably mounted on the bag placing tray 19, the bag pushing tail cylinder is fixedly mounted on the equipment frame 18 and is located below the bag placing tray 19, the output end of the bag pushing tail cylinder is connected to the bag pushing tail plate 20, the fixed bearing block 21 is fixedly mounted on the equipment frame 18 and is located at the rear end of the bag placing tray 19, the bag pressing tail block 22 is hinged on the fixed bearing block 21 through a spring hinge shaft, and the bag pushing tail plate 20 is provided with a groove adapted to the bag pressing tail block 22;

[0051] Bag pushing mechanism: The bag pushing tail cylinder drives the bag pushing tail plate 20 to move along the bag placing tray 19 to push the fungus bag to the specified position. The fixed bearing block 21 and the bag pressing tail block 22 ensure the stability during the bag pushing process and prevent the fungus bag from shifting.

[0052] The preferred solution of the mushroom bag production equipment of the above-mentioned three-station single-piece bag feeding device for edible mushroom bags is: the bag suction moving component 3 also includes a bag moving motor 24, a bag moving synchronous belt 26, a bag moving track 23, a bag moving synchronous pulley 25, a bag moving closer cylinder, a bag moving closer rack 31, a bag moving closer gear 32, a bag moving suction box mounting plate 27, a bag moving suction box lifting cylinder 29, and a bag moving suction box lifting guide rail 30. The bag moving motor 24 and the bag moving synchronous pulley 25 are respectively installed at both ends of the bag moving track 23, the bag moving synchronous belt 26 is sleeved on the output end of the bag moving motor 24 and the bag moving synchronous pulley 25, and the bag moving suction box lifting cylinder 29 is installed on the output end of the bag moving motor 24 and the bag moving synchronous pulley 25. The cylinder 29 is fixedly mounted on the bag transfer suction box mounting plate 27, the bag transfer suction box lifting cylinder 30 controls the extension and retraction of the bag transfer suction box lifting guide rail 30, the bag transfer suction box 28 is adapted to the bag transfer suction box lifting guide rail 30, the bag transfer suction box mounting plate 27 is connected to the bag transfer synchronous belt 26 through the mounting frame, and the mounting frame is slidably connected to the bag transfer track 23, the bag transfer cylinder is arranged on the bag transfer box mounting plate 27 of the bag transfer suction box 28 at B, and the bag transfer rack 31 is respectively arranged on the bag transfer box 28 at A and the bag transfer box 28 at C, and the output end of the bag transfer cylinder is adapted to the bag transfer rack 31 through the bag transfer gear 32;

[0053] Bag suction moving assembly 3: When there are bags in the three bag placing boxes, the bag moving motor 24 runs, and drives the three bag moving suction boxes 28 to move to the position of the bag placing box assembly 8 of group A through the transmission of the bag moving synchronous belt 26. At the same time, the bag moving cylinder moves to push the bag moving rack 31 to move, and the bag moving rack 31 pushes the bag moving gear 32 to rotate. The bag moving gear 32 is then transmitted to the bag moving rack 31 on the other side to move, so that the bag moving racks 31 on both sides can move symmetrically. Since the bag moving racks 31 on both sides are installed on the bag moving box mounting plates 27 of the bag moving suction boxes 28 at positions A and C, the movement of the bag moving cylinder can drive the bag moving suction boxes 28 at positions A and C to move closer to the middle, so as to achieve the moving and separation of the distance between the bag moving suction boxes 28;

[0054] When the three bag transfer sucking boxes 28 at positions A, B and C move to the top of the bag placing box assemblies A1, A2 and A3 under the guidance of the bag transfer track 23, the bag transfer sucking box lifting cylinder 29 is actuated, and under the guidance of the bag transfer sucking box lifting guide rail 30, the bag transfer sucking box 28 is driven to descend and enter the bag placing box assembly. At the same time, the bag taking fan 5 is turned on, the air suction switching valve 4 is actuated, and the suction box generates negative pressure. At the same time, the bag blowing member 14 is actuated to blow air into the bag in the bag box, so that the bag can be better attached to the suction box and can be more stably sucked up by the suction box.

[0055] After the bag transfer suction box 28 sucks up the bag, the bag transfer motor 24 reverses and the bag transfer suction box 28 returns to its original middle position, i.e., the C1, C2, and C3 positions corresponding to the bag placement tray assembly 10. The bag transfer suction box lifting cylinder 29 operates again to press the bag into the bag placement tray 19, and then the suction switching valve 4 operates again to disconnect the vacuum negative pressure, so that the bag is accurately placed on the corresponding bag placement tray 19, and then returns to its original position and waits for the next action.

[0056] The preferred solution of the mushroom bag production equipment of the above-mentioned three-station single-piece bag feeding device for edible mushroom bags is as follows: the bag opening rotating component 7 includes a base 39, a bag opening driving motor 38, a bag rubbing track 40, a bag rubbing driving cylinder 42, a bag opening lower suction box 37, a bag opening upper suction box 36, a bag opening rack 43, a bag covering driving motor 33, a bag covering connecting rod 34 and an adjusting shaft 35, the bag rubbing driving cylinder 42 and the bag covering driving motor 33 are installed on the box body 1 through a fixing frame, the bag rubbing track 40 and the bag opening upper suction box 36 are slidably installed on the base 39, and the bag opening lower suction box 37 is slidably installed on the bag rubbing track 40. A bag rubbing spring 41 is provided between the bag rubbing track 40 and the lower bag opening suction box 37, the output end of the bag rubbing driving cylinder 42 is adapted to the end of the lower bag opening suction box 37, the bag opening driving motor 38 is fixedly mounted on the base 39, the bag opening racks 43 are respectively arranged on the lower bag opening suction box 37 and the upper bag opening suction box 36, the output end of the bag opening driving motor 38 is adapted to the two bag opening racks 43 through the bag opening gear, the base 39 is fixedly mounted on the adjusting shaft 35, the output end of the bagging driving motor 33 is hinged to the bagging connecting rod 34, the adjusting shaft 35 is provided with an adjusting rod, and the bagging connecting rod 34 is hinged to the adjusting rod;

[0057] When the bags in the bag placing tray 19 are located at the specified position, the bag opening driving motor 38 starts to operate, and through the transmission of the bag opening gear and the bag opening rack 43, the upper bag opening suction box 36 and the lower bag opening suction box 37 are driven to open and close relative to each other. After the two suction boxes close the bag opening, the bag opening fan 6 starts to operate, the suction switching valve 4 is actuated, and the two suction boxes generate negative pressure to suck the bag opening.

[0058] The bag opening lower suction box 37 is installed on the bag rubbing track 40, and the bag rubbing driving cylinder 42 is activated. Under the action of the bag rubbing spring 41, the bag opening lower suction box 37 is pushed to move a distance and then return to its original position to realize the bag rubbing action. The purpose is to make the subsequent bag opening action more stable and avoid the failure of bag opening due to reasons such as the sticking of the bag mouth.

[0059] The bagging drive motor 33 runs, and the transmission is transmitted through the bagging connecting rod 34, driving the upper and lower suction boxes to swing 90 degrees. The bag can be rotated and moved to the bottom of the bagging station of the bagging machine. Then the bag opening drive motor 38 runs again, driving the two suction boxes to open, thereby sucking the bag opening into a square shape, so that the bagging mechanism of the three-station bagging machine equipment can better extend into the bag opening, and the bag is put into the turntable bagging barrel. When the bagging mechanism holds the bag opening, the bagging drive motor 33 reverses again, driving the upper and lower suction boxes back to the original position, preparing for the next action. The upper and lower suction boxes refer to the upper suction box 36 for bag opening and the lower suction box 37 for bag opening.

[0060] The preferred solution of the mushroom bag production equipment of the above-mentioned three-station single-piece bag feeding device for edible mushroom bags is as follows: two groups of suction switching valves 4 are provided, and the fan includes a bag taking fan 5 and a bag opening fan 6. The bag taking fan 5 is adapted to the bag transfer suction box 28 at A, B, and C through a group of suction switching valves 4, and the bag opening fan 6 is adapted to the lower bag opening suction box 37 and the upper bag opening suction box 36 through another group of suction switching valves 4. The suction switching valve 4 includes a suction switching cylinder 44, a suction switching piston 45, and a suction switching tee 46. The suction switching tee 46 is adapted to the bag transfer suction box 28 and the lower bag opening suction box 37 and the upper bag opening suction box 36 at A, B, and C through an air duct.

[0061] The suction switching valve 4 includes a suction switching cylinder 44, a suction switching piston 45, and a suction switching tee 46. When the suction cup needs to suck air to generate negative pressure, the suction switching cylinder 44 is activated to push the suction switching piston 45 to move, as shown in the figure, which can change the direction of the air and achieve the purpose of switching.

[0062] The working process of the mushroom bag production equipment of the edible mushroom bag three-station single-piece bag feeding device is as follows:

[0063] The whole bundle of single mushroom bags is manually placed neatly into the bag placing box assembly 8 of group A and the bag placing box assembly 9 of group B, and then the two groups of bag placing box assemblies are placed into the corresponding position slots.

[0064] The bag suction moving assembly 3 is in operation, and the bag transfer suction box 28 descends to a group of bag placing box assemblies to suck up a bag, and then moves to the bag placing tray assembly 10 to place the bag. When the number of bags in the bag placing tray 19 reaches a certain height, the bag transfer lifting mechanism will operate to raise the bag to a certain height so that the bag suction box can continue to suck the bag.

[0065] When the bags in a bag box are used up, the device will issue an alarm prompting the worker to replenish the bags in time. At this time, the bag suction moving component 3 will automatically switch to the bag box component on the other side to suck the bags without being affected by the lack of bags.

[0066] When the bag in the bag placing tray 19 is at the designated position, the bag opening rotating assembly 7 is actuated to clamp the bag mouth and open it. Subsequently, the device will deliver the opened bag to the designated position for subsequent bagging.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
