Description

Technical Field

[0001] This application relates to the field of plastic recycling, and in particular to a device for crushing and recycling waste materials from syringe injection molding. Background Technology

[0002] As a basic medical device, the syringe barrel is typically manufactured using injection molding. To improve production efficiency and meet supply demands, multi-cavity molds are usually used for one-time batch injection molding in actual production.

[0003] During the injection molding process of syringes, the molten plastic in the mold's gating system (such as the main runner and branch runners) cools and solidifies, forming injection residue. This residue cannot be used directly as a finished product, but its material is the same as that of the syringe product, making it valuable for recycling. Therefore, the residue usually needs to be crushed and recycled.

[0004] Currently, the common method for recycling waste materials involves feeding the waste materials into a crusher, where they are crushed by crushing rollers. The crushed particles are then screened by a filter screen located below the crushing rollers, and particles that meet the required size are discharged through the filter screen, thus completing the recycling process.

[0005] However, during the crushing process, due to the irregular shape of the residual material, the particle size of the crushed particles is often uneven. Larger residual particles tend to accumulate on the filter screen, gradually clogging the mesh, making it difficult for residual particles of the required size to pass through the filter screen smoothly and thus reducing the recycling efficiency of the residual material. Summary of the Invention

[0006] To improve the recycling efficiency of syringe residue, this application provides a syringe injection molding residue crushing and recycling device.

[0007] This application provides a device for crushing and recycling waste materials from syringe injection molding, which adopts the following technical solution:

[0008] A device for crushing and recycling waste materials from syringe injection molding includes a base frame, a crushing component, a collecting component, and a tilting component; The crushing assembly includes a housing and a crushing roller assembly; the housing is mounted on a base frame, and the crushing roller assembly is rotatably mounted inside the housing, the crushing roller assembly being used to crush residual materials; a feed inlet is provided on the housing; The flipping assembly includes a flipping frame, a flipping drive component, and an opening mechanism; The tilting frame includes a frame body, two filter elements, and an elastic element. The frame body is rotatably mounted inside the machine housing. The filter elements are mounted on the frame body via the elastic element. A material discharge port is provided on the frame body, and the elastic element drives the filter elements to close the material discharge port. The crushing roller assembly is located inside the frame body, and the two filter elements are arranged opposite each other on both sides of the crushing roller assembly. The tilting drive is mounted on the machine housing, and the tilting drive drives the frame body to rotate, causing the two filter elements to exchange positions. The opening mechanism is disposed inside the housing and is used to drive the filter element to rotate and open the discharge port. The housing is provided with a receiving chamber, and the collecting component is connected to the receiving chamber. The collecting component is used to collect the remaining material in the receiving chamber. When the discharge port near the feed inlet is open and the discharge port away from the feed inlet is closed, the remaining material passes through the feed inlet, the crushing roller group and the filter element away from the feed inlet in sequence before entering the receiving chamber.

[0009] By adopting the above technical solution, after one of the filter elements has been used as a filter screen for a period of time, the flipping drive drives the frame to rotate, causing the two filter elements to switch positions, thus realizing the alternating use of the filter elements. When the frame rotates, it can bring larger particles of residual material closer to the feed inlet for secondary crushing, improving the reliability of crushing and reducing the possibility of larger particles gradually clogging the filter elements and affecting the recovery efficiency.

[0010] Optionally, a transfer assembly is also included, which includes a moving mechanism and a clamping member; the moving mechanism is disposed on the base frame, and the clamping member is disposed on the moving mechanism; the moving mechanism is used to drive the clamping member to move, so that the clamping member clamps the remaining material in the mold and moves it to the feed port.

[0011] By adopting the above technical solution, the cooperation between the moving mechanism and the clamping component can automatically complete the action of grabbing the residual material from the mold and feeding it to the crushing component, further realizing the automation of the injection molding residual material recycling process, reducing manual operation links, and improving recycling efficiency.

[0012] Optionally, the filter element includes two filter plates, which are rotatably connected to the frame via corresponding elastic elements; the two filter plates move closer to each other under the drive of the corresponding elastic elements, thus closing the discharge port.

[0013] By adopting the above technical solution, the filter element consists of two filter plates forming an open structure. With the reset action of the elastic element, the filter element can automatically close under normal conditions, thereby filtering the residual material.

[0014] Optionally, the frame is provided with a limiting edge, and the filter plate abuts against the limiting edge.

[0015] By adopting the above technical solution, the limiting edge can restrict the rotation direction of the filter plate, reduce the possibility of the filter plate opening to the outside of the frame, and thus improve the reliability of filter plate filtration.

[0016] Optionally, the opening mechanism includes an opening element and a push rod; the opening element is disposed on the housing, and the push rod is disposed on the output end of the opening element; the opening element drives the push rod to move, so that the push rod pushes the filter plate to open the material discharge port.

[0017] By adopting the above technical solution, the opening component drives the push rod to push the filter plate, thereby realizing the opening of the material discharge port.

[0018] Optionally, the collection assembly includes a fan and a collection pipe; both the fan and the collection pipe are connected to the receiving chamber; the fan is used to generate airflow so that the remaining material in the receiving chamber enters the collection pipe.

[0019] By adopting the above technical solution, the airflow generated by the blower can be used to introduce the remaining material in the receiving chamber into the collection pipe, thereby facilitating collection.

[0020] Optionally, the crushing roller assembly includes two crushing roller mechanisms. Each crushing roller mechanism includes a crushing drive component, a roller body, and crushing teeth. The crushing drive component is mounted on the housing, the roller body is rotatably connected to the housing, and the crushing teeth are mounted on the roller body. The crushing teeth on the two roller bodies are staggered.

[0021] By adopting the above technical solution, when the surplus material enters between the two rollers, it can be crushed by the crushing teeth on the rollers.

[0022] Optionally, the tilting frame further includes a connector; the connector includes a connecting seat and a toothed ring, the frame body is connected to the connecting seat, the connecting seat is rotatably connected to the housing, and the toothed ring is disposed on the connecting seat; the tilting drive is drivenly connected to the toothed ring.

[0023] By adopting the above technical solution, the flipping drive component is connected to the gear ring drive, thereby driving the connecting seat to rotate relative to the machine housing, thus realizing the rotation of the flipping frame.

[0024] Optionally, a roller is rotatably mounted on the connecting seat, and a connecting groove is provided on the housing, wherein the roller is rotatably connected to the connecting groove.

[0025] By adopting the above technical solution, the rolling fit between the roller and the connecting groove reduces the frictional resistance between the connecting seat and the machine housing, thereby improving the smoothness of the tilting frame rotation.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a flipping component, after one of the filter elements has been used as a filter screen for a period of time, the flipping drive drives the frame to rotate, causing the two filter elements to switch positions, thus realizing the alternating use of the filter elements. When the frame rotates, it can bring larger particles of residual material closer to the feed inlet for secondary crushing, improving the reliability of crushing and reducing the possibility of larger particles gradually clogging the filter elements and affecting the recovery efficiency.

[0028] 2. By setting a limiting edge, the rotation direction of the filter plate can be restricted, reducing the possibility of the filter plate opening to the outside of the frame, thereby improving the reliability of filter plate filtration;

[0029] 3. By setting a connecting piece, the flipping drive is connected to the gear ring drive, thereby driving the connecting seat to rotate relative to the machine housing, thus realizing the rotation of the flipping frame. Attached Figure Description

[0041] The following combination Figures 1-10 This application will be described in further detail.

[0042] This application discloses a device for crushing and recycling waste materials from syringe injection molding. For example... Figure 1 As shown, the waste material crushing and recycling device includes a base frame 1, a transfer component 2, a crushing component 3, a collection component 4, and a tilting component 5.

[0043] Specifically, such as Figure 1 and Figure 2As shown, the transfer assembly 2 includes a moving mechanism 21 and a clamping member 22. The moving mechanism 21 includes a first translation member 211, a second translation member 212, a first rotating member 213, a second rotating member 214, and a support frame 215. The body of the first rotating member 213 is fixedly connected to the base frame 1, and its output end is fixedly connected to the support frame 215, which is rotatably connected to the base frame 1. The body of the first translation member 211 is slidably connected to the support frame 215, and its output end is fixedly connected to the body of the second rotating member 214, which is fixedly connected to the clamping member 22. The body of the second translation member 212 is fixedly connected to the support frame 215, and its output end is fixedly connected to the body of the first translation member 211.

[0044] like Figure 2 As shown, in this embodiment, the first rotating member 213 can drive the support frame 215 to rotate on the base frame 1; the second translating member 212 can drive the first translating member 211 to slide on the support frame 215; the first translating member 211 can drive the second rotating member 214 to perform linear motion; the second rotating member 214 can drive the clamping member 22 to rotate; preferably, the first translating member 211 and the second translating member 212 are both linear modules, the first rotating member 213 and the second rotating member 214 are both motors, and the clamping member 22 is a pneumatic gripper. Through the cooperation of the first translating member 211, the second translating member 212, the first rotating member 213, and the second rotating member 214, after the injection molding machine 6 opens the mold, the clamping member 22 is driven to move to the position of the mold and clamp the remaining material. After the clamping member 22 holds the excess material, the second translation member 212 first drives the clamping member 22 to move, causing the excess material to be ejected from the mold; then, the first translation member 211 drives the clamping member 22 to move away from the injection molding machine 6, thereby removing it from the range of the injection molding machine 6. After the clamping member 22 removes the excess material from the range of the injection molding machine 6, the first rotating member 213 and the second rotating member 214 work, causing the excess material to be adjusted from the vertical direction to the horizontal direction, and under the drive of the first translation member 211, the clamping member 22 moves the excess material to the position of the crushing component 3.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the crushing assembly 3 includes a housing 31 and a crushing roller assembly. The housing 31 is fixedly mounted on the base frame 1. A feed inlet 311 is provided on the housing 31. After the clamping member 22 transfers the residual material to the position of the feed inlet 311, it releases the residual material, allowing it to enter the housing 31 through the feed inlet 311. A receiving chamber 312 is provided inside the housing 31, located below the crushing roller assembly, for accommodating the residual material after crushing by the crushing roller assembly.

[0046] like Figure 4 and Figure 5 As shown, the crushing roller assembly includes two crushing roller mechanisms 32. Each crushing roller mechanism 32 includes a crushing drive component 321, a roller body 322, and crushing teeth 323. The roller body 322 is rotatably connected to the housing 31. The body of the crushing drive component 321 is fixedly mounted on the housing 31, and the output end of the crushing drive component 321 is fixedly connected to the roller body 322. The crushing drive component 321 can drive the roller body 322 to rotate within the housing 31. The crushing teeth 323 are fixedly disposed on the roller body 322, and the crushing teeth 323 on the two roller bodies 322 are staggered. In this embodiment, the crushing drive component 321 is a motor. The two roller bodies 322 rotate towards each other under the drive of the crushing drive component 321. When the residual material enters between the two roller bodies 322, the crushing teeth 323 disposed on the roller body 322 can crush the residual material.

[0047] like Figure 5 , Figure 6 and Figure 7 As shown, the flipping assembly 5 includes a flipping frame 51, a flipping drive component 52, an opening mechanism 53, and a connecting component 54. The flipping frame 51 includes a frame body 511, a filter component 512, and an elastic component 513. Two material discharge ports 5111 are provided on the frame body 511. The roller body 322 is located inside the flipping frame 51, and the two material discharge ports 5111 are arranged opposite each other on both sides of the roller body 322.

[0048] like Figure 5 and Figure 7 As shown, a filter element 512 is installed at the material inlet 5111. In this embodiment, the filter element 512 includes two filter plates 5121, which are rotatably connected to the frame 511 via corresponding elastic elements 513. Preferably, the elastic element 513 is a torsion spring. The two filter plates 5121 move closer to each other under the drive of the corresponding elastic elements 513, thereby closing the material inlet 5111. The filter plates 5121 have multiple filter holes 5122 to facilitate the screening of the crushed residue.

[0049] like Figure 6 and Figure 7 As shown, the connector 54 includes a connecting seat 541, a toothed ring 542, and rollers 543. The frame 511 is fixedly connected to the connecting seat 541, and the connecting seat 541 is rotatably connected to the housing 31. Specifically, a connecting seat 541 is installed at each end of the frame 511, and multiple rollers 543 are rotatably mounted on the circumference of the connecting seat 541. A connecting groove 313 is provided on the housing 31, and the sidewalls of the rollers 543 are in rolling contact with the inner wall of the connecting groove 313. Through the rolling engagement of the rollers 543 and the connecting groove 313, the frictional resistance between the connecting seat 541 and the housing 31 is reduced when the connecting seat 541 rotates relative to the housing 31, thereby improving the smoothness of the rotation of the tilting frame 51.

[0050] In addition, such as Figure 5 and Figure 7 As shown, a gear ring 542 is fixedly mounted on one of the connecting seats 541. The body of the flipping drive 52 is fixedly mounted on the housing 31. A gear is provided at the output end of the flipping drive 52, and the gear meshes with the gear ring 542. In this embodiment, the flipping drive 52 is a motor. The flipping drive 52 drives the connecting seat 541 to rotate relative to the housing 31 through the transmission connection between the gear and the gear ring 542, thereby causing the frame 511 to rotate.

[0051] like Figure 8 As shown, a limiting edge 5112 is fixedly connected to the frame 511. The limiting edge 5112 can restrict the rotation direction of the filter plate 5121, reduce the possibility of the filter plate 5121 rotating in the direction of the outside of the frame 511, and improve the reliability of the filter element 512 in screening the residual material.

[0052] like Figure 9 and Figure 10 As shown, the opening mechanism 53 includes an opening element 531 and a push rod 532. The opening element 531 includes a first opening drive element 5311, a second opening drive element 5312, and a connecting plate 5313. The body of the first opening drive element 5311 is fixedly mounted on the housing 31, and its output end is fixedly connected to the connecting plate 5313. The body of the second opening drive element 5312 is fixedly connected to the connecting plate 5313, and its output end is fixedly connected to the push rod 532. In this embodiment, the first opening drive element 5311 can drive the connecting plate 5313 to move horizontally, and the second opening drive element 5312 can drive the push rod 532 to move vertically. Preferably, both the first opening drive element 5311 and the second opening drive element 5312 are linear modules. Through the cooperation of the first opening drive element 5311 and the second opening drive element 5312, the filter plate 5121 can be rotated by the push rod 532. In this embodiment, two opening mechanisms 53 are installed. Each opening mechanism 53 pushes a filter plate 5121 to rotate, thereby opening the material discharge port 5111.

[0053] like Figure 4 and Figure 5As shown, a sealing plate 7 is also fixedly connected to the housing 31. The sealing plate 7 is located inside the frame 511 and can rotate relative to the frame 511. The roller 322 is rotatably connected to the sealing plate 7. The sealing plate 7 can limit the movement range of the residue during the crushing process, improving the reliability of the residue crushing. The rotation axis of the connecting seat 541 is parallel to the rotation axis of the roller 322. When the flipping drive 52 drives the frame 511 to rotate, the filter elements 512 on both sides rotate with the frame 511 around the axis of the connecting seat 541. At this time, the sealing plate 7 is fixed in position, and the roller 322 rotates relative to the sealing plate 7. Thus, after the positions of the two filter elements 512 are swapped, the residue can enter the crushing roller group from the open discharge port 5111 for crushing.

[0054] It should be noted that when the residual material is being crushed, the filter element 512 near the feed inlet 311 opens the corresponding discharge port 5111 under the push of the opening mechanism 53. At this time, the filter element 512 away from the feed inlet 311 closes the corresponding discharge port 5111 under the action of the elastic element 513.

[0055] After the waste material is fed into the feed inlet 311, it enters the crushing roller group inside the frame 511 through the opened discharge port 5111 for crushing. Specifically, when the push rod 532 is in the state of pushing the filter plate 5121 to open the discharge port 5111, the connecting plate 5313 is positioned between the discharge port 5111 and the feed inlet 311. Simultaneously, the filter plate 5121 is in an inclined state. The connecting plate 5313 and the filter plate 5121 provide guidance for the falling waste material, allowing it to smoothly enter between the two rollers 322 for crushing, thereby improving the crushing efficiency of the waste material.

[0056] After being crushed by the crushing roller assembly, the residual material falls onto the filter plate 5121 on the side away from the feed inlet 311. Residual material particles with the required particle size enter the receiving chamber 312 through the filter holes 5122 on the filter plate 5121, while larger residual material particles are intercepted by the filter plate 5121 and retained in the frame 511. After a specified time for residual material recycling, the flipping drive 52 drives the frame 511 to rotate, causing the positions of the two filter elements 512 to be interchanged.

[0057] After the positions of the two filter elements 512 are swapped, the filter element 512 that was originally away from the feed inlet 311 flips to a position closer to the feed inlet 311. The opening element 531 then drives the push rod 532 to move, causing the push rod 532 to push the filter plate 5121 to open the discharge port 5111, thus facilitating the continued entry of residual material into the crushing roller assembly for crushing. Simultaneously, the filter element 512 that was originally closer to the feed inlet 311 flips to a position away from the feed inlet 311, and under the action of the elastic element 513, closes the discharge port 5111, continuing to filter the crushed residual material. Specifically, before the positions of the two filter elements 512 are swapped, the opening element 531 drives the push rod 532 away from the filter element 512, causing the two filter plates 5121 to close the discharge ports 5111 under the elastic force of the elastic element 513. This also reduces the possibility of interference between the opening mechanism 53 and the rotating frame 51.

[0058] When the frame 511 rotates, it can bring the larger particles of residual material intercepted inside the frame 511 to a position near the feed inlet 311, so that the larger particles of residual material can enter the crushing roller group for secondary crushing, thereby improving the crushing efficiency of the residual material. At the same time, the alternating use of the two filter elements 512 reduces the possibility that the filter element 512 near the receiving chamber 312 will become gradually clogged due to long-term use, thus affecting the recovery efficiency.

[0059] like Figure 1 and Figure 9 As shown, the collection component 4 includes a blower 41 and a collection pipe 42, and the collection chamber 312 is connected to the blower 41 and the collection pipe 42 respectively. The blower 41 is fixedly installed on the base frame 1. During recycling, the airflow generated by the blower 41 causes the residual particles in the collection chamber 312 to be transported into the collection pipe 42 through the airflow, thereby facilitating the collection of the crushed residual material.

[0060] The implementation principle of the waste material crushing and recycling device for syringe injection molding in this application embodiment is as follows:

[0061] After the injection molding machine 6 completes injection and opens the mold, the moving mechanism 21 drives the clamping member 22 to move to the position of the mold. After the clamping member 22 clamps the remaining material in the mold, the moving mechanism 21 drives the clamping member 22 to move the remaining material to the top of the feed port 311 and releases the remaining material. The remaining material is then fed into the machine housing 31 from the feed port 311.

[0062] Before the residual material is fed in, the filter element 512 on the side closer to the feed inlet 311 opens the corresponding discharge port 5111 under the action of the opening mechanism 53, and the filter element 512 on the side farther away from the feed inlet 311 closes the corresponding discharge port 5111 under the action of the elastic element 513.

[0063] After the waste material is fed into the feed inlet 311, it enters the crushing roller assembly through the open discharge port 5111 for crushing. The crushed waste material falls onto the filter element 512 on the side away from the feed inlet 311. Waste material particles that meet the particle size requirements pass through the filter holes 5122 of the filter element 512 and enter the collection chamber 312. After the waste material enters the collection chamber 312, the airflow generated by the blower 41 carries the waste material particles in the collection chamber 312 into the collection pipe 42, thereby facilitating the centralized recovery of the waste material.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
