Description

Technical Field

[0001] This utility model relates to the field of black fungus bag making technology, specifically a black fungus bag making machine. Background Technology

[0002] Black fungus, also known as black vegetable, wood ear, or cloud ear, belongs to the Auriculariaceae family and the Auricularia genus. It is a precious medicinal and edible gelatinous fungus in my country and is also recognized worldwide as a health food. After drying, black fungus needs to be stored and transported in packaging bags.

[0003] For example, a medical plastic bag making machine with announcement number "CN222097162U" first seals the bottom and then cuts it. During the sealing process, the plastic bag sticks to the sealing plate, and lifting the sealing plate pulls on the plastic bag, causing it to stretch and resulting in a decrease in product quality. Furthermore, this device places the plastic bags above the conveyor belt during transport without any restraint, causing wrinkles to form during transport, resulting in poor quality after heat sealing. Additionally, after heat sealing, the device requires another device to cut the plastic bags, but it lacks a cutting function, indicating limitations in its design. Utility Model Content

[0004] The purpose of this invention is to solve the problems of plastic bags wrinkling during transportation, resulting in poor quality of heat-sealed plastic bags, and the limitations of the device due to its lack of cutting function. Therefore, a black fungus bag making machine is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A black fungus bag-making machine is designed, comprising a worktable and a first curved plate. The upper end of the worktable is fixedly connected to two first curved plates. A reciprocating structure is provided below each of the two first curved plates. Two second curved plates are fixedly connected to the upper end of the worktable. The second curved plates are slidably connected to two round rods. The upper ends of the two round rods are fixedly connected to a horizontal plate. The lower ends of the two round rods are fixedly connected to a third curved plate. A rotating structure is provided behind the third curved plate on the right side. A feeding plate is fixedly connected to the lower end of the worktable.

[0007] Preferably, a spring is sleeved on the outer wall of the round rod, and the two ends of the spring are fixedly connected to the second bent plate and the third bent plate, respectively.

[0008] Preferably, the reciprocating structure includes a second housing, the upper end of which is fixedly connected to a first curved plate, a second motor fixedly connected to the right end of the second housing, an incomplete bevel gear fixedly connected to the output end of the second motor, the output shaft of the second motor being rotatably connected to the second housing via a bearing, the incomplete bevel gear meshing with two bevel gears respectively, the bevel gears and spur gears being fixedly connected via a connecting rod, both ends of the connecting rod being rotatably connected to the second housing via bearings, the spur gear meshing with a rack, and the end of the rack being slidably connected to the second housing.

[0009] Preferably, a heat sealer is installed at the lower end of the rack in the reciprocating structure on the left, and a cutting blade is installed at the lower end of the rack in the reciprocating structure on the right.

[0010] Preferably, the rotating structure includes a first housing, the front end of which is fixedly connected to a third curved plate, the rear end of which is fixedly connected to a first motor, the output end of which is fixedly connected to a rotating rod, the output shaft of which is rotatably connected to the first housing via a bearing, the rotating rod being movably connected to one end of a first straight rod via a bearing, the middle part of which is slidably connected to a limiting block, the limiting block being slidably connected to the first housing via a pin, the other end of which is movably connected to a slider via a pin, the outer wall of which is slidably connected to a second straight rod, and the middle part of which is rotatably connected to the first housing via a bearing.

[0011] Preferably, both of the third bending plates are equipped with circular rollers inside, and both ends of the circular rollers are fixedly connected to the third bending plates through bearings. The rotation shaft in the middle of the second straight rod is fixedly connected to the rear end of the right circular roller.

[0012] The black fungus bag-making machine proposed in this utility model has the following advantages:

[0013] Through the cooperation of the rotating structure and the circular roller, the first motor is started to drive the rotating rod to rotate counterclockwise. The rotation of the rotating rod drives the first straight rod to move. The limiting block limits the first straight rod, causing it to slide inside the limiting block. The movement of the first straight rod drives the slider to slide inside the second straight rod. The movement of the slider drives the second straight rod to rotate. When the rotating rod rotates from the top to the bottom, the rotating rod continues to rotate, driving the second straight rod to rotate. When the rotating rod rotates from the bottom to the top, it drives the slider to move to the bottom of the second straight rod. During this process, the second straight rod stops rotating, achieving intermittent rotation. The rotation of the second straight rod drives the right circular roller to rotate. The rotation of the circular roller transports the plastic bag to the right. During the transportation of the plastic bag, it flattens the plastic bag, which can prevent the plastic bag from wrinkling during transportation and improve the heat sealing quality of the plastic bag.

[0014] Through the cooperation of the reciprocating structure and the cutting blade, the second motor drives the incomplete bevel gear to rotate. When the incomplete bevel gear rotates to mesh with the bevel gear on one side, it drives the bevel gear on the other side to rotate. The rotation of the bevel gear on one side drives the connecting rod, the bevel gear on the other side, and the spur gear to rotate. The rotation of the spur gear drives the rack to move. The movement of the rack drives the cutting blade to move, thus cutting the plastic bag. The plastic bag can be cut directly after heat sealing without the need for additional cutting devices, reducing the limitations of the device. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-7 :

[0025] In this embodiment, a black fungus bag making machine includes a workbench 1 and a first curved plate 2. The upper end of the workbench 1 is fixedly connected to two first curved plates 2. A reciprocating structure 9 is provided below each of the two first curved plates 2. Two second curved plates 4 are fixedly connected to the upper end of the workbench 1. The second curved plates 4 are slidably connected to two round rods 5. The upper ends of the two round rods 5 are fixedly connected to a horizontal plate 6. The lower ends of the two round rods 5 are fixedly connected to a third curved plate 7. A rotating structure 3 is provided behind the third curved plate 7 on the right side. A feeding plate 13 is fixedly connected to the lower end of the workbench 1. A spring 8 is sleeved on the outer wall of the round rod 5. The elastic coefficient of the spring 8 is selected according to the actual working requirements to meet the working needs. The two ends of the spring 8 are fixedly connected to the second curved plate 4 and the third curved plate 7 respectively.

[0026] See attached document Figure 1-2 And 6-7:

[0027] The reciprocating structure 9 includes a second housing 901, the upper end of which is fixedly connected to the first curved plate 2. A second motor 902 is fixedly connected to the right end of the second housing 901. The model of the second motor 902 is selected according to the actual working requirements. An incomplete bevel gear 903 is fixedly connected to the output end of the second motor 902. The output shaft of the second motor 902 is rotatably connected to the second housing 901 through a bearing. The rotation of the output shaft of the second motor 902 can drive the incomplete bevel gear 903 to rotate. The incomplete bevel gear 903 is meshed with two bevel gears 904 respectively. The bevel gears 904 and spur gears 906 are fixedly connected through a connecting rod 905. When the incomplete bevel gear 903 rotates to mesh with one side bevel gear 904, it can drive the bevel gear 904 on one side to rotate, and at the same time drive the other side bevel gear 904, connecting rod 905 and spur gear 906 to rotate.

[0028] Both ends of the connecting rod 905 are rotatably connected to the second housing 901 via bearings. The spur gear 906 meshes with the rack 904. The end of the rack 907 is slidably connected to the second housing 901. The rotation of the spur gear 906 can drive the rack 907 to move. A heat sealer 10 is installed at the lower end of the rack 907 in the left reciprocating structure 9, and a cutting blade 11 is installed at the lower end of the rack 907 in the right reciprocating structure 9. The movement of the racks 907 on both sides drives the heat sealer 10 and the cutting blade 11 to move respectively.

[0029] See attached document Figure 1 and 4 -5:

[0030] The rotating structure 3 includes a first housing 301. The front end of the first housing 301 is fixedly connected to the third curved plate 7. The rear end of the first housing 301 is fixedly connected to a first motor 302. The model of the first motor 302 is selected according to the actual working requirements. The output end of the first motor 302 is fixedly connected to a rotating rod 303. The output shaft of the first motor 302 is rotatably connected to the first housing 301 through a bearing. The rotation of the output shaft of the first motor 302 can drive the rotating rod 303 to rotate. The rotating rod 303 is movably connected to one end of a first straight rod 304 through a bearing. The middle part of the first straight rod 304 is slidably connected to a limiting block 305. The limiting block 305 is slidably connected to the first housing 301 through a pin. The rotation of the rotating rod 303 can drive the first straight rod 304 to move. At the same time, the limiting block 305 limits the movement of the first straight rod 304.

[0031] The other end of the first straight rod 304 is movably connected to the slider 306 via a pin. The outer wall of the slider 306 is slidably connected to the second straight rod 307. The movement of the first straight rod 304 can drive the slider 306 to slide inside the second straight rod 307. The middle part of the second straight rod 307 is movably connected to the first housing 301 via a bearing. The sliding of the slider 306 inside the second straight rod 307 can drive the second straight rod 307 to rotate. Both third curved plates 7 are equipped with rollers 12 inside. Both ends of the rollers 12 are fixedly connected to the third curved plates 7 via bearings. The rotation shaft in the middle of the second straight rod 307 is fixedly connected to the rear end of the right roller 12. The rotation of the second straight rod 307 can drive the roller 12 to rotate. The surface of the roller 12 is textured to prevent slippage.

[0032] Working principle:

[0033] First, the plastic bag is passed from left to right under the left roller 12, the heat sealer 10, the right roller 12, and the cutter 11. The elastic force of multiple springs 8 makes the roller 12 adhere to the plastic bag.

[0034] Material loading work:

[0035] Connect the external power supply to the first motor 302, start the first motor 302 to drive the rotating rod 303 to rotate counterclockwise (e.g. Figure 4The rotating rod 303 rotates, driving the first straight rod 304 to move. The limiting block 305 limits the first straight rod 304, causing it to slide inside the limiting block 305. The movement of the first straight rod 304 drives the slider 306 to slide inside the second straight rod 307. The movement of the slider 306 drives the second straight rod 307 to rotate. When the rotating rod 303 rotates from the top to the bottom, the rotating rod 303 continues to rotate, driving the second straight rod 307 to rotate 180 degrees. When the rotating rod 303 rotates from the bottom to the top, it drives the slider 306 to move to the bottom of the second straight rod 307. During this process, the second straight rod 307 no longer rotates, achieving intermittent rotation. The rotation of the second straight rod 307 drives the right-side roller 12 to rotate, and the rotation of the roller 12 conveys the plastic bag to the right.

[0036] Heat sealing and cutting operations:

[0037] The external power supply of the two second motors 902 is connected, and the two second motors 902 are started at the same time to drive the incomplete bevel gear 903 to rotate. When the incomplete bevel gear 903 rotates to mesh with the bevel gear 904 on one side, it drives the bevel gear 904 on one side to rotate. The rotation of the bevel gear 904 on one side drives the connecting rod 905, and the bevel gear 904 and spur gear 906 on the other side to rotate. The rotation of the spur gear 906 drives the rack 907 to move. The movement of the two racks 907 drives the heat sealer 10 and the cutter 11 to move respectively. When the plastic bag stops conveying, the heat sealer 10 and the cutter 11 move to the bottom end to perform heat sealing and cutting work on the plastic bag respectively.

[0038] Place the collection box under the feeding plate 13. The cut plastic bags will fall into the collection box to collect the plastic. The plastic bags can be used to package the black fungus.

[0039] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
