Description

Technical Field

[0001] This utility model relates to the technical field of waste recycling devices, specifically to a waste recycling device for a polypropylene straw machine for oral liquid medicine. Background Technology

[0002] Oral liquid medications refer to liquid drug preparations for patients to take orally. They are widely used in the medical field. To facilitate oral administration, a polypropylene straw is attached to the side of the medicine bottle, allowing patients to inhale the liquid medication. Polypropylene straw machines are used in the production of polypropylene straws. However, during the production of polypropylene straws, defects in the raw materials or errors in the cutting length may result in the production of some non-compliant polypropylene straws. To avoid wasting raw materials, these waste polypropylene straws are usually recycled and reused to produce compliant polypropylene straws.

[0003] When recycling these polypropylene straw wastes, they are crushed, then melted and extruded to form new polypropylene straws. During the crushing of these polypropylene straw wastes, due to the space inside the polypropylene straws and the elasticity and irregularity of their tubular structure, even a small number of them will occupy a large amount of space. Utility Model Content

[0004] This utility model proposes a waste recycling device for a polypropylene straw machine for oral liquid medicine, which solves the problem in the prior art that the polypropylene straw is not flattened during crushing, thus easily occupying the internal space of the crusher.

[0005] The technical solution of this utility model is as follows:

[0006] A waste recycling device for an oral liquid pharmaceutical polypropylene straw machine includes a crushing box and several support frames, as well as a mounting block, a feeding plate, an extrusion assembly, a pushing assembly, and a discharging assembly. The mounting block is fixedly installed between the support frames and has a through groove. The feeding plate is slidably installed through the side of the mounting block. The extrusion assembly is disposed on the mounting block and is used to flatten the polypropylene straw. The pushing assembly is disposed on the side of the mounting block and is used to push the extruded polypropylene straw down. The discharging assembly is disposed on the side of the mounting block and is used to move the feeding plate to expose the through groove of the mounting block.

[0007] Furthermore, the extrusion assembly includes a movable frame, a hydraulic cylinder, an extrusion plate, and a fixing assembly. Slide grooves are provided on both sides of the mounting block, and the movable frame is slidably installed in the slide grooves. The hydraulic cylinder is installed on the movable frame, and the extrusion plate is fixedly connected to the output end of the hydraulic cylinder. The fixing assembly is disposed on the mounting block for fixing the movable frame.

[0008] Furthermore, the fixing component includes a fixing rod and a positioning rod. The sides of the movable frame and the mounting block are respectively provided with fixing holes and fixing grooves, and the fixing rod is adapted to the fixing holes and the fixing grooves. The positioning rod is fixedly installed on the side of the mounting block.

[0009] Furthermore, the pushing assembly includes an electric cylinder and a pushing plate. The electric cylinder is installed on the side of the mounting block, and a through groove is provided on the side of the mounting block. The pushing plate is disposed in the through groove of the mounting block, and the pushing plate is fixedly connected to the output end of the electric cylinder.

[0010] Furthermore, the feeding assembly includes a support cover, a reciprocating screw, a screw nut, a motor, a slide rod, a slider, and a connecting rod. Two support covers are provided, each fixedly installed on both sides of the mounting block. The reciprocating screw is rotatably installed inside one of the support covers, and the screw nut is installed on the reciprocating screw. The slide rod is fixedly installed inside the other support cover, and the slider is slidably installed on the slide rod. The motor is installed on the side of the support cover, and its output end is coaxially connected to the reciprocating screw. Two connecting rods are provided, each fixedly installed on the side of the screw nut and the slider, and the other end of each connecting rod is fixedly installed on the side of the feeding plate.

[0011] Furthermore, when the positioning rod is in contact with the side of the movable frame, the fixing hole of the movable frame and the fixing groove of the mounting block are at the same horizontal position, and the pressing plate is located directly above the through groove of the mounting block.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] In this invention, when recycling polypropylene straws, the polypropylene straws are placed on top of the feeding plate in the through groove of the mounting block. Then, the extrusion assembly extrudes the polypropylene straws on the feeding plate to flatten them. After flattening, the feeding assembly pulls the feeding plate to move, thereby exposing the through groove of the mounting block. Then, the pushing assembly pushes the flattened polypropylene straws, causing them to fall from the through groove of the mounting block into the crushing box for crushing. This device, through the cooperation between the mounting block, feeding plate, extrusion assembly, pushing assembly, and feeding assembly, can flatten the polypropylene straws before crushing them, improving the space utilization rate during waste recycling.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-6As shown, this embodiment proposes a waste recycling device for an oral liquid pharmaceutical polypropylene straw machine. After the oral liquid pharmaceutical polypropylene straw machine generates waste, the polypropylene straw waste is placed into the waste recycling device. The device includes a crushing box 1 and several support frames 2, as well as a mounting block 3, a feeding plate 4, an extrusion assembly, a pushing assembly, and a discharging assembly. The mounting block 3 is fixedly installed between the support frames 2, and a through groove is provided on the mounting block 3. The feeding plate 4 is slidably installed through the mounting block 3 on its side. The extrusion assembly is located on the mounting block 3 and is used to flatten the polypropylene straw. The pushing assembly is located on the side of the mounting block 3 and is used to push the extruded polypropylene straw down. The discharging assembly is located on the side of the mounting block 3 and is used to move the feeding plate 4, exposing the through groove of the mounting block 3.

[0024] When recycling polypropylene straws, non-compliant polypropylene straws are first placed into the groove of mounting block 3. At this time, the discharge plate 4 penetrates through mounting block 3, causing the polypropylene straws to fall onto the discharge plate 4. Then, the extrusion assembly flattens the polypropylene straws, such as... Figure 2 As shown, the extrusion assembly includes a movable frame 5, a hydraulic cylinder 6, an extrusion plate 7, and a fixing assembly. Slide grooves are provided on both sides of the mounting block 3, and the movable frame 5 is slidably installed in the slide grooves. The hydraulic cylinder 6 is installed on the movable frame 5, and the extrusion plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. The fixing assembly is set on the mounting block 3 for fixing the movable frame 5. The fixing assembly includes a fixing rod 8 and a positioning rod 9. Fixing holes and fixing grooves are respectively provided on the sides of the movable frame 5 and the mounting block 3, and the fixing rod 8 is adapted to the fixing holes and fixing grooves. The positioning rod 9 is fixedly installed on the side of the mounting block 3.

[0025] Specifically, before inserting the polypropylene straw, the movable frame 5 can be moved horizontally, causing the extrusion plate 7 to move to one side, thus exposing more of the through groove of the mounting block 3, making it easier to place the polypropylene straw inside. After placement, the movable frame 5 is moved horizontally until its side is aligned with the side of the positioning rod 9. When the positioning rod 9 is aligned with the side of the movable frame 5, the fixing hole of the movable frame 5 and the fixing groove of the mounting block 3 are at the same horizontal level, and the extrusion plate 7 is directly above the through groove of the mounting block 3. Then, the fixing rod 8 is inserted into the fixing hole of the movable frame 5 and the fixing groove of the mounting block 3 to fix the movable frame 5. At this time, the extrusion plate 7 is directly above the through groove. Then, the hydraulic cylinder 6 is activated, and the hydraulic cylinder 6 moves the extrusion plate 7 downward. After downward movement, the outer wall of the extrusion plate 7 is aligned with the inner wall of the through groove, thus ensuring that the polypropylene straw in the through groove is completely extruded. And during extrusion, if... Figure 5As shown, the feeding plate 4 passes through the mounting block 3. When the extrusion plate 7 applies force to the feeding plate 4, the mounting block 3 can support the feeding plate 4. The inner side wall of the mounting block 3 is provided with a sliding groove. The feeding plate 4 is slidably installed in the sliding groove by the sliding block. Therefore, when the feeding plate 4 moves, the slider can also provide a certain support for the feeding plate 4.

[0026] After being flattened, as Figure 3 , Figure 4 and Figure 6 As shown, the polypropylene suction tube is fed into the crushing box 1 via a pushing assembly and a discharging assembly. The pushing assembly includes an electric cylinder 10 and a pushing plate 11. The electric cylinder 10 is mounted on the side of the mounting block 3, and a through groove is provided on the side of the mounting block 3. The pushing plate 11 is placed in the through groove of the mounting block 3 and is fixedly connected to the output end of the electric cylinder 10. The discharging assembly includes a support cover 12, a reciprocating screw 13, a screw nut 14, a motor 15, a slide rod 16, a slider 17, and a connecting rod 18. Two support covers 12 are provided, and the two support covers 12 are fixed respectively. Installed on both sides of mounting block 3, reciprocating screw 13 is rotatably installed inside one of the support covers 12, screw nut 14 is installed on reciprocating screw 13, slide rod 16 is fixedly installed inside the other support cover 12, slider 17 is slidably installed on slide rod 16, motor 15 is installed on the side of support cover 12, and the output end of motor 15 is coaxially connected to reciprocating screw 13. Two connecting rods 18 are provided, and the two connecting rods 18 are respectively fixedly installed on the side of screw nut 14 and slider 17, and the other end of connecting rod 18 is fixedly installed on the side of feeding plate 4.

[0027] Specifically, firstly, motor 15 is started, which drives reciprocating screw 13 to rotate within support cover 12. Screw nut 14 moves on reciprocating screw 13. It should be noted that screw nut 14 and reciprocating screw 13 are driven by rolling threads. When screw nut 14 moves, it drives one of the connecting rods 18 to move. Connecting rod 18 drives the feeding plate 4 to move out of mounting block 3. Under the drive of the other connecting rod 18, slider 17 moves on sliding rod 16, causing feeding plate 4 to move horizontally. At the same time, electric cylinder 10 is started, which drives pusher plate 11 to move forward, pushing polypropylene suction tube on feeding plate 4 out. Thus, it falls into crushing box 1 in through groove of mounting block 3 for crushing. It should be noted that crushing box 1 is located below through groove of mounting block 3. Then, the crushing rod in crushing box 1 rotates to crush the flattened polypropylene suction tube.

[0028] Working principle: When recycling polypropylene straws, first place the polypropylene straws into the through groove of the mounting block 3, so that they accumulate on the discharge plate 4. Then, move the moving frame 5 horizontally so that the side of the moving frame 5 fits against the positioning rod 9. Then, insert the fixing rod 8 into the fixing hole and fixing groove of the moving frame 5 and the mounting block 3 to fix them. Start the hydraulic cylinder 6. The hydraulic cylinder 6 drives the extrusion plate 7 to move down. The extrusion plate 7 flattens the polypropylene straws on the discharge plate 4. After flattening, start the motor 15 so that the discharge plate 4 slowly slides out of the mounting block 3. At the same time, start the electric cylinder 10. The electric cylinder 10 pushes the pusher plate 11 forward, pushing the polypropylene straws on the discharge plate 4 down so that they fall into the crushing box 1 for crushing, thus completing the recycling of polypropylene straw waste.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
