Description

Technical Field

[0001] This utility model belongs to the field of straw cutting and packaging technology, and in particular relates to an integrated straw cutting and packaging machine. Background Technology

[0002] Chinese utility model patent CN212859534U discloses a straw secondary cutting device, including a frame, a long straw holding device, a straw equalizing conveying device, and a straw cutting device. The upper end of the frame is fixedly connected to the long straw holding device, and the bottom of the long straw holding device is provided with a discharge port. The straw equalizing conveying device is located directly below the discharge port of the long straw holding device to evenly distribute and convey the long straws in the long straw holding device to the straw cutting device. The straw cutting device is located on the side of the long straw equalizing conveying device to cut the straws on the straw equalizing conveying device. The straw equalizing conveying device includes a first drive motor and an equalizing conveying roller. The rotating shaft of the first drive motor is fixedly connected to the equalizing conveying roller. Six feeding rings are symmetrically arranged on the roller surface of the equalizing conveying roller. Several straw grooves are evenly arranged on the feeding rings, and the straws can be fixed into the straw grooves. The blade of the straw cutting device is located in the center of the equalizing conveying roller.

[0003] However, while the above solution achieves cutting precision, the short straws may be irregular and their arrangement may be disrupted during the process of being conveyed to the short straw hopper by the conveyor belt.

[0004] The inventors discovered that during the process of sending the slit straws to the short straw hopper via a conveyor belt, the short straws were irregular and their arrangement was disrupted. They found that when a single straw was slit and fell onto the conveyor belt, the two ends would not fall at the same time. This caused the straws to change their posture when they fell onto the conveyor belt, resulting in irregular arrangement of the straws during the subsequent packaging process. Summary of the Invention

[0005] The purpose of this utility model embodiment is to provide a straw cutting and packaging integrated machine, which aims to solve the technical problem that the short straws are irregular and their arrangement order is disrupted when they are sent to the short straw hopper by the conveyor belt after being cut.

[0006] The present invention is implemented as follows:

[0007] A straw cutting and packaging integrated machine includes a hopper, a sorting device at the bottom of the hopper, and sealing devices with identical structures on both sides of the bottom of the sorting device. The sorting device is equipped with a feeding gear, and a cutter is located in the middle of the feeding gear. The feeding gear is used to sort the straws from the bottom of the hopper and then feed them to the cutter for cutting and dropping them into the sorting device. The sorting device is equipped with two counter-arranged cylinders to feed the cut straws into the sealing devices respectively.

[0008] Furthermore, the sorting device includes two first sorting grooves, each of which is disposed below the feeding gear to receive the straws that are cut at the feeding gear.

[0009] Furthermore, a second sorting groove is fixed below each of the first sorting grooves. A horizontal push cylinder is fixed to the unopened end of the second sorting groove. A push plate is fixed to the piston rod of the horizontal push cylinder to push the suction tube that falls into the second sorting groove into the second sealing film, and then enter the sealing device for sealing under the conveyor belt.

[0010] Furthermore, the feeding gear includes a first feeding gear, a second feeding gear, a third feeding gear, and a fourth feeding gear, wherein the fourth feeding gear and the first feeding gear form a group, the second feeding gear and the third feeding gear form a group, and a cutting groove is provided between the first feeding gear and the third feeding gear, and a cutting blade is provided in the cutting groove.

[0011] Furthermore, the cutting edge of the cutter intersects the arc of the feeding gear, and the extension of the intersection line does not pass through the center of the feeding gear; the outer circumference of the feeding gear is provided with a toothed notch that matches the outer circle of the suction tube.

[0012] Furthermore, a first guide plate in an arc shape is provided between the fourth feeding gear and the first feeding gear. The starting section of the first guide plate is located inside the bottom of the toothed notch, and the ending section of the first guide plate is located outside the toothed notch, which is used to peel the straw out from the toothed notch. The second feeding gear and the third feeding gear are provided with a second guide plate. The starting section of the second guide plate is arc-shaped and concentric with the feeding gear, and located outside the circumference of the feeding gear. The starting section of the second guide plate is arc-shaped or straight, which is used to guide the cut straw so that the straw can enter the first sorting groove of another line of defense.

[0013] Furthermore, a vibrator is provided on the outer side wall of the hopper to prevent the suction tubes inside the hopper from accumulating and leaking out from the bottom outlet.

[0014] Furthermore, the hopper is equipped with a sorting gear, which is driven by a belt pulley. The sorting gear is used to move the suction tube in the hopper to prevent the suction tube from being squeezed and blocked.

[0015] Furthermore, after riveting is completed, the bottom of the hopper is provided with a guide groove, the top of the guide groove is provided with a funnel-shaped guide groove opening, and the bottom of the guide groove is provided with an arc-shaped guide plate. The arc-shaped guide plate cooperates with the feeding gear to feed the suction tube into the toothed notch of the feeding gear.

[0016] Furthermore, the first sorting groove is provided with a first baffle and a second baffle arranged at an angle; the first baffle is fixed to the inner side of the side wall of the first sorting groove; the second baffle is located opposite the first baffle and reciprocates by being pushed by the inclined push cylinder; the end of the second baffle is located below the first baffle; the distance from the end of the first baffle to the second baffle is H, where H ≤ the diameter of the straw.

[0017] The positive effects of this invention are as follows: The straws are individually fed from the hopper by a feeding gear and secured around its circumference. As the straws pass the cutter, they are cut into two pieces and enter the sorting device. Two counter-arranged cylinders then feed the cut straws into the sealing device. This process cuts long straws into shorter ones, which are then neatly arranged in the sorting device before being sent to the sealing device for packaging. The use of two workstations effectively improves packaging efficiency. The two sealing devices are positioned on either side of the sorting device, improving packaging efficiency while also providing an optimized layout for the equipment. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1 to 8 The diagram shown is a structural diagram of a straw cutting and packaging integrated machine provided in an embodiment of this utility model. It includes a hopper 1, a sorting device 4 at the bottom of the hopper 1, and sealing devices 3 with the same structure on both sides of the bottom of the sorting device. The sorting device 4 is provided with a feeding gear, and a cutter 407 is provided in the middle of the feeding gear. The feeding gear is used to sort the straws from the bottom of the hopper and then transport them to the cutter 407 for cutting and dropping them into the sorting device 4. The sorting device 4 is provided with two cylinders arranged in opposite directions to send the cut straws into the sealing devices respectively.

[0031] In this embodiment of the invention, the straws are individually fed out of the hopper 1 by the feeding gear and are caught on the circumference of the feeding gear. When the straws pass through the cutter 407, they are cut into two pieces and enter the sorting device 4. Two counter-arranged cylinders then feed the cut straws into the sealing device 4. This design allows long straws to be cut into short straws and neatly placed in the sorting device before being sent to the sealing device 4 for packaging. The use of two stations for packaging effectively improves packaging efficiency. The two sealing devices 4 are arranged on both sides of the sorting device 4, which not only improves packaging efficiency but also provides an optimized layout for the rational arrangement of equipment.

[0032] Specifically, such as Figures 1 to 8 As shown, a straw cutting and packaging integrated machine includes a hopper 1. The bottom of the hopper 1 is provided with a sorting device 4, and the bottom of the sorting device is provided with sealing devices 3 of the same structure on both sides. The sorting device 4 is provided with a feeding gear, and the middle of the feeding gear is provided with a cutter 407. The feeding gear is used to sort the straws from the bottom of the hopper and then feed them to the cutter 407 for cutting and falling into the sorting device 4. The sorting device 4 is provided with two cylinders arranged in opposite directions to send the cut straws into the sealing devices respectively.

[0033] The sorting device 4 includes two first sorting grooves 402, each of which is disposed below the feeding gear to receive the straw that is cut at the feeding gear.

[0034] Each first sorting groove 402 is provided with a first baffle 4021 and a second baffle 4022 arranged at an angle; the first baffle 4021 is fixed to the inner side of the side wall of the first sorting groove 402; the second baffle 4022 is located opposite the first baffle 4021 and reciprocates by being pushed by the inclined push cylinder 403.

[0035] Preferred, such as Figure 5As shown, when the second baffle 4022 is fully extended, its end is located below the first baffle 4021. With this design, when the straw is cut, it first falls onto the surface of the first baffle 4021. As it slides on the inclined surface of the first baffle 4021, it is subjected to gravity. When it slides to the position where it contacts the second baffle 402, it tends to become regular under the action of the inclined surfaces of the first baffle 4021 and the second baffle 4022 and gravity.

[0036] Preferred, such as Figure 5 As shown, when the second baffle 4022 is fully extended, its end is located below the first baffle 4021, and the distance from the end of the first baffle 4021 to the second baffle 4022 is H, where H ≤ the diameter of the straw. Under the action of friction and other adhesion forces on the straw surface, some straws will be in a vertically downward or nearly vertically downward state when they are detached from the feeding gear. If the straw falls directly into the second sorting groove 411, it will cause the straws in the second sorting groove 411 or the vertically positioned straws in the second sorting groove 411 to have an irregular posture. However, with this design, when the straw is cut, it first falls onto the surface of the first baffle 4021. When sliding on the inclined surface of the first baffle 4021, it is subjected to gravity. When it slides to the position of contact with the second baffle 402, it tends to be in a regular state under the action of the inclined surfaces of the first baffle 4021 and the second baffle 4022 and gravity. At the same time, the distance H has three effects:

[0037] A straw falling vertically downward or nearly vertically downward will be blocked and clamped when passing through the gap between the first baffle 4021 and the second baffle 4022. The reciprocating motion of the second baffle 4022 will restore it to its normal state.

[0038] Straws that cannot fall off in time will not be flattened within the gap of distance H, and will not affect the use of the straws;

[0039] To prevent the first baffle 4021 and the second baffle 4022 from colliding during mechanical vibration.

[0040] Preferably, H ≤ half the diameter of the straw;

[0041] Below each first sorting groove 402, there is a second sorting groove 411. A horizontal push cylinder 401 is fixed to the unopened end of the second sorting groove 411. A push plate is fixed to the piston rod of the horizontal push cylinder 401 to push the straw that falls into the second sorting groove into the second sealing film 503, and then enter the sealing device 3 for sealing under the conveyor belt.

[0042] Two sealing devices 3 with identical structures are fixed on both sides of the sorting device 4 and driven by a first motor 6 and a second motor 601, respectively. Taking the first motor 6 as an example, the output shaft 602 of the first motor 6 is connected to the transmission shaft 203 via a belt or chain. The transmission shaft 203 drives the conveyor belt 204 inside the conveyor 2 to rotate. At the same time, the end of the transmission shaft 203 is also provided with a first bevel gear 201. The second bevel gear 202, which meshes with the first bevel gear 201, transmits power to the second rotating wheel 302 at the top. The second rotating wheel 302 is connected to the first rotating wheel 301 and the third rotating wheel 303 via gear meshing or belt drive, respectively driving the second guide wheel 305 and the first guide wheel 304. Similarly, the first right guide wheel 3041 is also driven in the same way. With this driving method, the conveying and sealing devices can be driven to rotate simultaneously by one motor, saving energy.

[0043] Meanwhile, the preferred drive second guide wheel 305 and first guide wheel 304 have heat sealing function, and the heat sealing strip 306 also has heat sealing function. Users can flexibly choose one or use them in combination according to specific packaging structure requirements. Heat sealing technology is existing technology and will not be described in detail here.

[0044] Each conveyor 2 is provided with a sealing film fixing shaft 5 below it. The sealing film fixing shaft 5 is rotatably fixed with a sealing film roller 501. The sealing film on the sealing film roller 501 is wrapped around the end of the conveyor belt 204 of the conveyor 2 by the first section of sealing film 502, and wrapped around the outlet end of the second sorting trough 411 by the second section of sealing film 503. Then, the sealing is achieved by passing through the sealing device 3 by the third section of sealing film 504.

[0045] In particular, such as Figure 8 The feeding gear shown is driven by a pulley 101 and includes a first feeding gear 405, a second feeding gear 409, a third feeding gear 410, and a fourth feeding gear 412. The fourth feeding gear 412 and the first feeding gear 405 form one group, and the second feeding gear 409 and the third feeding gear 410 form another group. A cutting groove 406 is provided between the first feeding gear 405 and the third feeding gear 410, and a cutter 407 is provided within the cutting groove 406. The end of the cutter 407 is fixed to the side wall surface of the grain bin 1 or to the frame of this invention. Preferably, the cutting edge of the cutter 407 intersects the arc of the feeding gear, and the extension of the intersection line does not pass through the center of the feeding gear. The outer circumference of the feeding gear has a toothed notch that matches the outer circle of the suction tube. Preferably, the cutting edge of the cutter 407 is tangent to the bottom of the toothed notch.

[0046] A first guide plate 404 is provided between the fourth feeding gear 412 and the first feeding gear 405. The first guide plate 404 is arc-shaped. The starting section of the first guide plate 404 is located inside the bottom of the toothed notch, and the ending point of the first guide plate 404 is located outside the toothed notch. It is used to peel the straw out from the toothed notch.

[0047] The second feeding gear 409 and the third feeding gear 410 are provided with a second guide plate 408. The starting section of the second guide plate 408 is arc-shaped and concentric with the feeding gear, and located outside the circumference of the feeding gear. The starting section of the second guide plate 408 is arc-shaped or straight-shaped and is used to guide the cut straw so that the straw can enter the first sorting groove 402 in another direction.

[0048] In particular, such as Figure 5 As shown, a vibrator 102 is provided on the outer side wall of the hopper 1. The vibrator is a commercially available vibrator used to prevent the suction tubes in the hopper 1 from accumulating and leaking out from the bottom outlet. A feeding gear is provided at the outlet, which feeds the suction tubes out for cutting.

[0049] In particular, such as Figure 6 As shown, the hopper is equipped with a sorting gear 4051, which is also driven by a belt pulley. The sorting gear 4051 is used to move the suction tube in the hopper 1 to prevent the suction tube from being squeezed and blocked.

[0050] In particular, such as Figure 7 As shown, the hopper is equipped with a sorting gear 4051, which is also driven by a belt pulley. The bottom of the hopper 1 is equipped with a guide groove 104, the top of the guide groove 104 is equipped with a flared guide groove opening 103, and the bottom of the guide groove 104 is equipped with an arc-shaped guide plate. The arc-shaped guide plate cooperates with the feeding gear to send the suction tube into the toothed notch of the feeding gear.
