A straw production line

Abstract

This application relates to a straw production line, including a single-cutting mechanism, a single-cutting hopper, a slitting mechanism, a dual-channel hopper, a dual-channel transport mechanism, a first packaging machine, and a second packaging machine. The single-cutting hopper receives straws cut by the single-cutting mechanism. The slitting mechanism slits the straws in the single-cutting hopper. The slit straws enter the dual-channel hopper and are transported by the dual-channel transport mechanism to the first packaging machine and the second packaging machine for packaging. The single-cutting mechanism and the slitting mechanism are arranged obliquely or perpendicularly. By adopting a multi-cutting mechanism layout, the single-cutting mechanism first pre-cuts extra-long straws, and the pre-cut straws are then slit by the slitting mechanism and transported by the dual-channel transport mechanism to the two packaging machines for packaging. This allows the application to configure two packaging machines in one production line, thereby improving the automated production efficiency of straws.

Description

Technical Field

[0001] This application belongs to the field of straw manufacturing technology, specifically relating to a straw production line. Background Technology

[0002] Among existing straw production equipment, such as the pharmaceutical straw production equipment and structure disclosed in CN115431482A, the pharmaceutical straw production equipment includes an injection molding machine, an extrusion mold, a cooling and drying assembly, a traction assembly, and a shearing device. The cooling and drying assembly includes a first cooling chamber, a second cooling chamber, a drying box, a heat exchange box, multiple heat sinks, a first water pump, a second water pump, a spiral tube, and an air pump. Under the traction of the traction assembly, the long straw extruded by the extrusion mold passes through the first cooling chamber, the second cooling chamber, and the drying box, and enters the shearing device. When the long straw passes through the first cooling chamber, the water is heated. When the hot water passes through the heat exchange box, it exchanges heat with the gas in the spiral tube. The heated air is pressurized by the air pump and blown into the drying box to dry the long straw that has passed through the drying box. This eliminates the need for compressed air for drying, thus solving the problem of high cost in existing pharmaceutical straw production equipment.

[0003] For example, CN211388067U discloses an automated device for producing U-shaped straws, relating to the field of straw processing technology. It includes a base plate, with a mounting column fixedly connected to the upper outer wall of the base plate. A mounting frame is fixedly connected to the end of the mounting column away from the base plate. A conveyor belt assembly is rotatably connected inside the mounting frame. A straightening device is fixedly connected to the upper end of the base plate, and a grinding device is fixedly connected to the upper outer wall of the base plate. A first drive motor is connected to the output end of the conveyor belt assembly, and the surface of the first drive motor is fixedly connected to the base plate. In this invention, when a straw falls onto the surface of the conveyor belt assembly, a spring pushes a straightening plate to rotate on the surface of the mounting arm. The straightening plate evenly arranges the straws on the surface of the conveyor belt assembly. The first drive motor drives the conveyor belt assembly to rotate, thereby arranging the straws on the surface of the conveyor belt assembly and avoiding the problem of straws accumulating on the surface of the conveyor belt assembly.

[0004] For example, CN211363375U discloses a colored straw extrusion device, which relates to the field of straw technology. It includes two support rods, a positioning rod fixedly connected to one side wall of each support rod, and a discharge device on one side wall of the positioning rod. A cold water tank is fitted onto the support rods, and cooling devices are installed on both side walls of the cold water tank. A straw cutting device is installed on one side wall of the cold water tank. The discharge device includes an extruder fixedly connected to one side wall of the positioning rod, and a feed hopper fixedly connected to one end of the extruder. The cooling device circulates water from the cold water tank and sprays it onto the straws to cool them, effectively improving water utilization and ensuring uniform cooling of the straws, thus increasing the product yield. The use of support rods, a discharge device, and a straw cutting device effectively centralizes the equipment, avoiding excessively long production lines and wasting space, and improving the ease of use of the equipment. A filter screen effectively removes excess water droplets from the straws.

[0005] As exemplified above, the existing technologies used in the automated production of straws all employ a single-cut method. This means the injection-molded tubes are directly cut to obtain the corresponding straws, which are then sent to a packaging machine for packaging. Depending on the packaging format, there are single-pack and multi-pack options. A single-pack refers to one straw per package, while a multi-pack refers to multiple straws per package, such as 6-pack, 8-pack, 12-pack, etc. However, currently, the number of straws cut by a single cutting mechanism per unit time far exceeds the number of straws packaged by the packaging machine per unit time. For example, a cutting mechanism might cut 30 straws per unit time, while the packaging machine packages only one 6-pack per unit time. This forces the cutting mechanism to slow down to match the packaging machine, thus limiting the efficiency of automated straw production. Summary of the Invention

[0006] In order to overcome the technical problems mentioned in the background art, this application provides a straw production line.

[0007] This application provides a straw production line, including a single-cutting mechanism, a single-cutting hopper, a slitting mechanism, a dual-channel hopper, a dual-channel transport mechanism, a first packaging machine, and a second packaging machine. The single-cutting hopper is used to receive straws cut by the single-cutting mechanism. The slitting mechanism is used to slit the straws in the single-cutting hopper. The slit straws enter the dual-channel hopper and are transported to the first packaging machine and the second packaging machine respectively by the dual-channel transport mechanism for packaging. The single-cutting mechanism and the slitting mechanism are arranged obliquely or vertically in orientation.

[0008] Furthermore, the discharge end of the single-cutting mechanism is provided with a first conveying mechanism to transfer the suction tube cut by the single-cutting mechanism to the single-cutting hopper. The first conveying mechanism includes a first conveying frame and a first conveyor belt. A first baffle and a second baffle are installed on the first conveying frame. The first baffle and the second baffle are respectively arranged on both sides of the first conveyor belt.

[0010] Furthermore, the single-cutting hopper includes a receiving plate and a receiving bin. Limited push plates are respectively arranged on both sides of the receiving plate. The limited push plates are connected to the first telescopic unit. The receiving plate is arranged corresponding to the receiving bin to guide the cut straws into the receiving bin. The receiving bin is provided with a straw sorting mechanism. The straw sorting mechanism includes a first gripper and a second gripper. The first gripper and the second gripper are both arranged on a mounting plate. The mounting plate is movably arranged on a mounting rod. The mounting plate is connected to the telescopic end of the second telescopic unit. The receiving bin is provided with a first slot and a second slot corresponding to the first gripper and the second gripper.

[0011] Furthermore, the suction tubes in the single-cutting hopper are transported to the slitting mechanism by a robotic arm. The single-cutting hopper also includes a hopper housing. The receiving plate is provided at the upper end of the hopper housing. The receiving hopper is located on one side of the hopper housing. The receiving hopper is connected to a third telescopic unit. The third telescopic unit drives the receiving hopper to rise and fall. When the receiving hopper rises to a preset height, one side of the receiving hopper blocks the receiving plate, and the suction tubes accumulate in the receiving plate. When the receiving hopper descends, the suction tubes accumulated in the receiving plate fall into the receiving hopper.

[0012] Furthermore, the straw sorting mechanism is disposed inside the hopper box, and the bottom plate of the receiving hopper is provided with a first sorting groove and a second sorting groove respectively corresponding to the first groove and the second groove on one side of the receiving hopper.

[0013] Furthermore, the robotic arm includes a mounting base, a fourth telescopic unit, a first robotic gripper, and a second robotic gripper. Both the first and second robotic grippers are rotatably mounted on the mounting base. The mounting base is connected to the fourth telescopic unit. The first and second robotic grippers are driven to rotate on the mounting base by a pneumatic component to achieve gripping and releasing actions. The first robotic gripper and / or the second robotic gripper are connected to the mounting base by a buffer spring.

[0014] Furthermore, the slitting mechanism includes a slitting seat, on which a turntable is rotatably mounted. The turntable has multiple grooves for placing straws. A brush assembly is provided corresponding to the turntable. A cutting assembly is provided on the slitting seat and is located on one side of the turntable. A tilt-limiting assembly is provided on the slitting seat. The tilt-limiting assembly includes a tilt-limiting mounting plate and a tilt-limiting rod. The tilt-limiting mounting plate is fixed to the slitting seat, and the tilt-limiting rod is fixed to the tilt-limiting mounting plate and is located above the turntable to prevent the straws located in the grooves from tilting up.

[0015] Furthermore, the slitting seat is also provided with a waste-kicking assembly, which includes a waste-kicking frame and multiple waste-kicking rods. The multiple waste-kicking rods are installed on the waste-kicking frame and are positioned above the turntable.

[0016] Furthermore, the dual-channel transport mechanism includes a second conveying mechanism, a third conveying mechanism, a fourth conveying mechanism, and a fifth conveying mechanism. The bottom of the dual-channel hopper is inclined, and the dual-channel hopper is located between the second conveying mechanism and the third conveying mechanism. The second conveying mechanism is provided with a first partition plate to divide the second conveying mechanism into a first feeding area and a second feeding area. The dual-channel hopper is divided into a first storage area and a second storage area by the second partition plate. The fifth conveying mechanism is provided with a third partition plate to divide the fifth conveying mechanism into a third feeding area and a fourth feeding area. The suction tubes on the first feeding area and the second feeding area are conveyed to the first storage area and the second storage area under the action of the first brush assembly. The suction tubes in the first storage area and the second storage area are fed into the third conveying mechanism and the fourth conveying mechanism under the action of the second brush assembly. The third conveying mechanism and the fourth conveying mechanism are used to deliver the suction tubes to the third feeding area and the fourth feeding area, respectively.

[0017] The advantages of this application are:

[0018] This application adopts a multi-cutting mechanism layout. The single-cutting mechanism first performs preliminary cutting on the extra-long straws, and then the straws are further cut by the slitting mechanism and sent to two packaging machines for packaging through a dual-channel transport mechanism. This allows the application to configure two packaging machines in one production line, thereby improving the automated production efficiency of straws.

[0019] The overall layout of this application can adopt a zigzag layout design to reduce the floor space required, allowing for integration in a relatively small factory and facilitating the management and control of various production processes for straws. Attached Figure Description

Detailed Implementation

[0029] The following examples are merely illustrative of the invention, and the scope of the invention is not limited to the embodiments described. Therefore, any non-essential modifications and adjustments made by those skilled in the art based on the above description to other embodiments are still within the scope of protection of this invention.

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] This application provides a straw production line, including a single-cutting mechanism 100, a single-cutting hopper 200, a slitting mechanism 300, a dual-channel hopper 400, a dual-channel transport mechanism 500, a first packaging machine 600, and a second packaging machine 700. The single-cutting hopper 200 is used to receive the straws cut by the single-cutting mechanism 100. The slitting mechanism 300 is used to slit the straws in the single-cutting hopper 200. The slit straws enter the dual-channel hopper 400 and are transported by the dual-channel transport mechanism 500 to the first packaging machine 600 and the second packaging machine 700 for packaging. The single-cutting mechanism 100 and the slitting mechanism 300 are arranged obliquely or vertically in terms of orientation.

[0032] This straw production line can produce straws based on extra-long straws. The extra-long straws can be produced using an injection molding machine. The produced straws are then fed to a single-cutting mechanism 100 via a conveying mechanism (such as a conveyor belt). This single-cutting mechanism 100 can use a commercially available straw cutting machine to cut the straws into straws of a set length. Since the cutting speed of the single-cutting mechanism 100 is significantly higher than that of the slitting mechanism 300, the cut straws are temporarily stored in the single-cutting hopper 200 before being fed into the slitting mechanism 300, thus avoiding speed mismatch issues. The slitting mechanism 300 then performs a second cut, dividing the straws into two segments, each conforming to the designed straw length. These segments are then temporarily stored in a dual-channel hopper 400 and subsequently fed into the first packaging machine 600 and the second packaging machine 700 via a dual-channel transport mechanism 500. This application, through the above-mentioned straw production line design, adopts a dual-cutting unit structure design and cooperates with two packaging machines to ensure that the packaging speed of straws is matched as closely as possible to the cutting speed of the two cutting units, thereby improving the automated production efficiency of straws.

[0033] In this straw production line, the single-cutting mechanism 100 and the splitting mechanism 300 are arranged obliquely or vertically in terms of orientation, such as... Figure 1 The diagram shows a vertical layout, which forms a figure-7 shape, reducing the floor space required for the production line. This allows for integration in a relatively small factory and facilitates the management and control of various straw production processes.

[0034] In some embodiments, to address the disordered phenomenon that occurs after the single-cutting area - the straw is cut and conveyed out, the discharge end of the single-cutting mechanism 100 has been optimized, such as... Figure 2As shown, the discharge end 101 of the single-cutting mechanism 100 is provided with a first conveying mechanism 800 to transfer the straws cut by the single-cutting mechanism 100 to the single-cutting hopper 200. The first conveying mechanism 800 includes a first conveying frame 801 and a first conveyor belt 802. A first baffle 803 and a second baffle 804 are installed on the first conveying frame 801. The first baffle 803 and the second baffle 804 are respectively arranged on both sides of the first conveyor belt 802.

[0035] In this embodiment, by setting a first baffle 803 and a second baffle 804, the straws that come out after molding are limited to avoid the problem of straws being messy, so as to ensure that the straws can be well conveyed to the single-cutting bin 200 by the first conveyor belt 802.

[0036] In some embodiments, to prevent the straw from tilting up, such as Figure 3 As shown, a vertical baffle 805 is provided above the first conveyor belt 802. The vertical baffle 805 is disposed on a baffle shaft 806. The baffle shaft 806 is rotatably disposed at the discharge end of the single cutting mechanism 100 via a hinge assembly 807.

[0037] Through the design of the rotatable vertical baffle 805, during the operation of the single-cutting mechanism 100, the vertical baffle 805, as... Figure 3 As shown, the distance between its bottom and the first conveyor belt 802 should be slightly greater than the outer diameter of the suction tube to prevent tilting. In the event of routine maintenance, the vertical baffle 805 can be lifted upwards using the hinge assembly 807 and the rotating shaft 806, thus avoiding interference with the daily maintenance or replacement of easily damaged parts of the single-cutting mechanism 100.

[0038] In some embodiments, considering the problem that the suction tubes conveyed to the single-cutting hopper 200 after single-cutting are not neatly arranged, affecting subsequent cutting, the structure of the single-cutting hopper 200 has been optimized. For example... Figure 4 and Figure 5As shown, the single-cutting hopper 200 includes a receiving plate 201 and a receiving bin 202. Limiting push plates 203 are respectively arranged on both sides of the receiving plate 201. The limiting push plates 203 are connected to a first telescopic unit 204. The receiving plate 201 is arranged corresponding to the receiving bin 202 to guide the cut straws into the receiving bin 202. A straw organizing mechanism 205 is provided on the receiving bin 202. The straw organizing mechanism 205 includes a first gripper 2051 and a second gripper 2052. Both the first gripper 2051 and the second gripper 2052 are disposed on a mounting plate 2053. The mounting plate 2053 is movably disposed on a mounting rod 2054. The mounting plate 2053 is connected to the telescopic end of the second telescopic unit 2055. A first slot 206 and a second slot 207 are provided on the receiving bin 202 corresponding to the first gripper 2051 and the second gripper 2052.

[0039] This embodiment organizes the straws in the single-cutting hopper 200 in two ways. The first way is that before entering the receiving hopper 202, two movable limiting plates 203 are set at the receiving plate 201. The spacing between the limiting plates 203 is controlled by the first telescopic unit 204, thereby limiting the feeding distance of the straws and ensuring that the straws can fall into the receiving hopper 202 relatively neatly. The spacing between the two limiting plates 203 is determined according to the length of the straws after preliminary cutting in the actual production process, for example, about 1mm wider than the length of the straws.

[0040] Secondly, considering that even with the initial sorting achieved by the two limiting plates 203 using this vertical dropping method, some disorder may still remain, a straw sorting mechanism 205 was designed. This straw sorting mechanism 205 utilizes the second telescopic unit 2055 to push the first gripper 2051 and the second gripper 2052 through the first slot 206 and the second slot 207 into the receiving bin 202. Subsequently, it can be made to swing left and right on the mounting rod 2054, simulating the leveling of the straw by a human hand. The mounting rod 2054 can be implemented as a lead screw assembly, which can be connected to a servo motor. Under the action of the servo motor, the first gripper 2051 and the second gripper 2052 swing left and right on the mounting rod 2054.

[0041] In some embodiments, a single-cutting hopper 200 is provided to feed materials to the cutting mechanism 300, such as... Figure 4-6As shown, the suction tubes in the single-cutting hopper 200 are transported to the slitting mechanism 300 by the robotic arm 900. The single-cutting hopper 200 also includes a hopper body 208. The receiving plate 201 is provided at the upper end of the hopper body 208. The receiving hopper 202 is provided on one side of the hopper body 208. The receiving hopper 202 is connected to a third telescopic unit 209. The third telescopic unit 209 drives the receiving hopper 202 to rise and fall. When the receiving hopper 202 rises to a preset height, one side of the receiving hopper 202 blocks the receiving plate 201, and the suction tubes accumulate in the receiving plate 201. When the receiving hopper 202 descends, the suction tubes accumulated in the receiving plate 201 fall into the receiving hopper 202.

[0042] Since this embodiment uses a robotic arm 900 to grasp the straws, in order to cooperate with the grasping of the robotic arm 900, the receiving bin 202 is raised and lowered by the third telescopic unit 209. When it is necessary to grasp, the receiving bin 202 is raised. At this time, the receiving bin 202 blocks the receiving plate 201 to form a receiving groove, so as to accumulate the straws. After the robotic arm 900 has grasped part or all of the straws in the receiving bin 202, the receiving bin 202 is lowered to receive the straws accumulated in the receiving groove. After the straws are sorted by the straw sorting mechanism 205, the above process is repeated to realize the feeding of the single cutting bin 200 to the cutting mechanism 300.

[0043] In some embodiments, the straw sorting mechanism 205 is disposed inside the hopper housing 208. The bottom plate of the receiving hopper 202 is provided with a first sorting groove 210 and a second sorting groove 211 respectively corresponding to the first slot 206 and the second slot 207 on one side of the receiving hopper 202, so as to facilitate the sorting operation of the first gripper 2051 and the second gripper 2052 and ensure that the straws in the receiving hopper 202 are relatively flat.

[0044] In some embodiments, considering the large force and difficulty in control during robotic gripping, the structure of robotic arm 900 has been improved, such as... Figure 6 As shown, the robotic arm 900 includes a mounting base 901, a fourth telescopic unit 902, a first robotic gripper 903, and a second robotic gripper 904. The first robotic gripper 903 and the second robotic gripper 904 are rotatably mounted on the mounting base 901. The mounting base 901 is connected to the fourth telescopic unit 902. The first robotic gripper 903 and the second robotic gripper 904 are driven to rotate on the mounting base 901 by a pneumatic component 905 to achieve gripping and releasing actions. The first robotic gripper 903 and / or the second robotic gripper 904 are connected to the mounting base by a buffer spring 906.

[0045] The robotic arm 900 drives the first robotic gripper 903 and the second robotic gripper 904 to rotate via the actuation component 905 to grasp the straw. The fourth telescopic unit 902 is used to adjust the height of the two robotic grippers for better straw grasping. The design of the buffer spring 906 makes it easier to control the two robotic grippers when grasping and easier to reset when releasing.

[0046] In some embodiments, such as Figure 7 As shown, the slitting mechanism 300 includes a slitting seat 301, a turntable 302 rotatably mounted on the slitting seat 301, a plurality of grooves 303 for placing straws on the turntable 302, a brush assembly 304 corresponding to the turntable 302, a cutting assembly 305 mounted on the slitting seat 301, the cutting assembly 305 being located on one side of the turntable 302, and a tilt-limiting assembly 309 mounted on the slitting seat 301, the tilt-limiting assembly 309 including a tilt-limiting mounting plate 3091 and a tilt-limiting rod 3092, the tilt-limiting mounting plate 3091 being fixed to the slitting seat 301, and the tilt-limiting rod 3092 being fixed to the tilt-limiting mounting plate 3091 and located above the turntable 302 to prevent the straws located in the grooves 303 from tilting up.

[0047] The working principle of the 300 slitting mechanism is as follows:

[0048] The straw is fed into the groove 303 in the turntable 302 via the brush assembly 304. The limiting rod 3092 prevents the straw from tilting up in the groove 303, thus preventing the straw from being cut and resulting in a defective product. The cutting assembly 305 is fixed and cuts the straw in the groove 303 of the rotating turntable 302, splitting the straw in half, thereby completing the straw cutting.

[0049] In some embodiments, such as Figure 7 As shown, the slitting seat is also provided with a waste removal component 306. The waste removal component 306 includes a waste removal frame 307 and a plurality of waste removal rods 308. The plurality of waste removal rods 308 are installed on the waste removal frame 307 and are located above the turntable 302.

[0050] In practical implementation, if a straw is encountered that is raised, one end of the scrap kicking rod 308 is set as a bevel, so that when the straw rotates with the turntable 302, the scrap kicking rod 308 will push the raised straw out of the groove 303, thus preventing the raised straw from entering the cutting component 305 and being cut into a defective product.

[0051] In some embodiments, such as Figure 8As shown, the dual-channel transport mechanism 500 includes a second conveying mechanism 501, a third conveying mechanism 502, a fourth conveying mechanism 503, and a fifth conveying mechanism 504. The bottom of the dual-channel hopper 400 is inclined, and the dual-channel hopper 400 is located between the second conveying mechanism 501 and the third conveying mechanism 502. The second conveying mechanism 501 is provided with a first partition plate 505 to divide the second conveying mechanism 501 into a first feeding area 5011 and a second feeding area 5012. The dual-channel hopper 400 is divided into a first storage area 402 and a second storage area 403 by the second partition plate 401. The fifth conveying mechanism 504 is provided with... A third partition plate 506 is provided to divide the fifth conveying mechanism 504 into a third feeding area 5041 and a fourth feeding area 5042. The straws on the first feeding area 5011 and the second feeding area 5012 are conveyed to the first storage area 402 and the second storage area 403 under the action of the first brush assembly 507. The straws in the first storage area 402 and the second storage area 403 are fed into the third conveying mechanism 502 and the fourth conveying mechanism 503 under the action of the second brush assembly 508. The third conveying mechanism 502 and the fourth conveying mechanism 503 are used to send the straws to the third feeding area 5041 and the fourth feeding area 5042, respectively.

[0052] The dual-channel transport mechanism 500 is used to transport the two types of straws cut by the cutting mechanism 300 separately. The second transport mechanism 501, through the first partition plate 505, divides the straws into a first feeding area 5011 and a second feeding area 5012 for diverting the straws. Under the action of the first brush assembly 507, the straws enter the first storage area 402 and the second storage area 403 of the dual-channel hopper 400, which are divided by the second partition plate 401. The straws in the dual-channel hopper 400 are then fed into the third transport mechanism 502 and the fourth transport mechanism 503 under the action of the second brush assembly 508. The third transport mechanism 502 and the fourth transport mechanism 503 then feed the straws into the third feeding area 5041 and the fourth feeding area 5042 of the fifth transport mechanism 504, and finally, they are transported to two packaging machines for packaging.

[0053] It should be noted that the two packaging machines can perform the same packaging or different packaging. Since the dual-channel transport mechanism 500 is a diverted transport, the speed of the material entering the first packaging machine 600 and the second packaging machine 700 is adjustable. For example, the first packaging machine 600 can perform 6-packaging, and the second packaging machine 700 can perform 12-packaging. Or, the first packaging machine 600 and the second packaging machine 700 can both perform 6-packaging, etc.
