Description

Technical Field

[0001] This utility model relates to the field of rubber recycling equipment for injection molding machines, and in particular to a rubber recycling device for a barrel. Background Technology

[0002] With the widespread use of plastic products in industrial production and daily life, injection molding technology, as the core process for plastic product processing, has been applied in various fields such as home appliances, automobiles, and daily necessities. Consequently, injection molding machines have become key equipment on production lines. In actual injection molding production, changes in product specifications, colors, or material properties necessitate frequent changes to the raw materials used in the injection molding machine. At this time, the barrel of the injection molding machine inevitably retains residual material from the previous batch that was not fully injected. If not thoroughly cleaned, this residual material will mix with the new raw material, leading to quality problems such as uneven color and substandard performance in subsequent products. Therefore, the cleaning and recycling of residual material is an indispensable part of the material changeover process.

[0003] Currently, the industry mainly adopts the traditional "new material feeding + manual post-processing" model for handling residual rubber materials in injection molding machines. The specific process is as follows: First, new raw materials to be produced are added to the barrel of the injection molding machine. Using the pushing force of the new raw materials, the residual rubber materials in the barrel are extruded from the nozzle in multiple times. Each extruded rubber material is in the form of irregular small lumps. The operator must immediately use simple tools such as iron bars to repeatedly roll and press them to force the rubber material into a thin sheet. If the rubber material is not pressed thin, its volume or thickness will exceed the feeding limit of the conventional crusher, making it impossible to crush. After the thin sheet rubber material cools naturally to room temperature, it is then manually transferred to the crusher for crushing. Only the crushed material can be used as "secondary material" (recycled material) and reused in the production of some low-requirement products.

[0004] However, the aforementioned traditional processing methods have many insurmountable drawbacks, specifically: low efficiency and high reliance on manual labor; low material recycling rate and serious waste, as manual shaping with iron rods makes it difficult to ensure the consistency of the rubber material's shape, easily resulting in uneven thickness and large size differences. Rubber materials that are too thick or too large in volume may not be able to be crushed by a pulverizer; the recycled materials are easily contaminated, as manual operations are mostly carried out in open environments (such as on the ground or on simple workbenches), and the rubber material is very susceptible to contamination by various impurities during shaping and transportation, leading to a decrease in the purity of the recycled "secondary materials".

[0005] In summary, existing methods for handling residual rubber materials in injection molding machines can no longer meet the demands of "high efficiency, low cost, and high-quality recycling" in modern injection molding production. The pain points of low efficiency, high labor costs, material waste, and easy pollution have become key factors restricting injection molding companies from reducing costs, increasing efficiency, and achieving green production. Therefore, developing a device that can replace manual operation and realize automated shaping, cooling, and recycling of residual rubber materials has become an urgent technical problem to be solved in the industry. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned technical problems and provide a recycling device that directly cuts the rubber material in the barrel into granules for recycling.

[0007] A barrel rubber material recycling device includes a hot runner connecting pipe, a forming mold device, a conveying device, a cooling water tank, a pelletizing table, and a recycling bin. The barrel rubber material recycling device is movably installed next to an injection molding machine. One end of the hot runner connecting pipe is connected to the barrel of the injection molding machine, and the other end is connected to the inlet of the forming mold device. The hot runner connecting pipe is used to convey rubber material from the barrel of the injection molding machine to the forming mold device. The forming mold device is used to break down the rubber material into multiple rubber strips. The outlet of the forming mold device is opposite to the transmission device, so that the multiple rubber strips are output from the outlet to the transmission device. The conveying device is used to transfer the multiple rubber strips. After the rubber strips are transferred to the cooling water tank for cooling and solidification, the solidified rubber strips are further transferred to the pelletizing table to be cut into granular rubber particles. The outlet of the pelletizing table is connected to the recycling bin, and the recycling bin is used to collect the rubber particles.

[0008] According to the barrel rubber recycling equipment of this application, a complete automated process for rubber recycling is established. Precise docking between the injection molding machine and the recycling equipment is achieved through a hot runner connection pipe, conveying the extruded clumps of rubber from the barrel to the forming mold device, preventing spillage or contamination during transfer. The forming mold device breaks down the rubber into regular rubber strips, solving the problem of inconsistent rubber size in traditional manual forming. A conveying device replaces manual transfer, reducing contact between the rubber and external impurities while achieving continuous conveying. A cold water tank and a pelletizing table work together to cool and shape the rubber strips, which are then collected centrally in a recycling bin. The entire process requires no manual intervention, significantly improving recycling efficiency and reducing labor costs. Furthermore, the recycled rubber granules are regular in shape and can be directly reused as "secondary material," reducing material waste. The barrel rubber recycling equipment is mobile, allowing it to provide barrel rubber recycling functionality for multiple injection molding machines, avoiding the need for redundant rubber recycling equipment for multiple injection molding machines.

[0009] Furthermore, it also includes a fixing frame with a mounting surface. A receiving cavity for accommodating the conveying device is formed on the lower side of the mounting surface. The shaping mold device is fixed to the mounting surface, and the discharge port of the shaping mold device is vertically aligned with the transmission device. The fixing frame enables the integrated installation of all core components. The mounting surface provides stable support for the shaping mold device, preventing it from shifting due to vibration during the extrusion of the adhesive material, ensuring precise alignment between the discharge port and the conveying device, and preventing the adhesive strip from falling off.

[0010] Furthermore, the fixing frame faces at least one opening, and the conveying device conveys the rubber strip out from the opening. The cooling water tank, pelletizing table, and recycling bin are sequentially arranged along the path from which the rubber strip is conveyed. The cooling water tank, pelletizing table, and recycling bin are arranged sequentially along the conveying path, forming a continuous process of "conveyance-cooling-cutting-collection," eliminating the need for additional transfer of the rubber strip and avoiding uneven cooling or damage during transfer. This layout ensures close connection between each link, reduces the residence time of the rubber material in the process, further improves recycling efficiency, and facilitates operators to observe the working status of each link and promptly identify and troubleshoot abnormalities.

[0011] Furthermore, the forming die device includes an extrusion device and a discharge die. The discharge port is located on the discharge die. The extrusion device compresses the rubber material, causing it to be extruded from the discharge port and broken into multiple rubber strips. The extrusion device can push the rubber material with stable pressure, avoiding poor discharge or strip breakage due to insufficient thrust. The specialized structure of the discharge die can precisely control the number and cross-sectional dimensions of the rubber strips, ensuring that each strip has a consistent shape and solving the problem of uneven thickness in traditional manual forming. The regular rubber strips can not only be uniformly cooled in the cold water tank, but also form uniformly sized rubber particles when cut on the pelletizing table, meeting the material morphology requirements for "two-material" reuse and reducing waste caused by irregular rubber strips that cannot be cut or crushed.

[0012] Furthermore, it also includes a movable platform, on which the forming mold device, conveying device, cooling water tank, pelletizing table, and recycling bin are mounted. The movable platform is designed to be slidable. The barrel material recycling equipment is pushed to each injection molding machine via the movable platform.

[0013] Furthermore, an observation window is provided on the side of the activity platform. This observation window allows for convenient monitoring of the recycling process and facilitates the handling of any accidents that may occur during the recycling process.

[0014] Furthermore, the cooling water tank is elongated, and multiple supporting beams are arranged along its length within the tank. The elongated shape of the cooling water tank ensures sufficient cooling of the rubber strip, while the multiple supporting beams support the strip, preventing excessive deformation during cooling and thus avoiding interference with the pelletizing table's cutting of the strip.

[0020] The present invention relates to a material barrel rubber recycling device, described in conjunction with the accompanying drawings.

[0021] like Figure 1Embodiment 1 of a barrel rubber recovery device shows a hot runner connecting pipe 3, a forming mold device 4, a conveying device 5, a cooling water tank 6, a pelletizing table 7, and a recovery box 8. The barrel 11 rubber recovery device is movably arranged beside an injection molding machine 1. One end of the hot runner connecting pipe 3 is connected to the barrel 11 of the injection molding machine 1, and the other end is connected to the inlet 41 of the forming mold device 4. The hot runner connecting pipe 3 is used to transport the rubber material from the barrel 11 of the injection molding machine 1 to the forming mold device 4. In this process, the shaping mold device 4 is used to decompose the rubber material into multiple strips. The outlet of the shaping mold device 4 is opposite to the transmission device, so that the multiple strips are output from the outlet to the transmission device. The conveying device 5 is used to transfer the multiple strips. After the strips are transferred to the cooling water tank 6 for cooling and solidification, the solidified strips are further transferred to the pelletizing table 7 to be cut into granules. The outlet of the pelletizing table 7 is connected to the recycling box 8, which is used to collect the granules. The 11 rubber material recycling equipment establishes a complete automated process for rubber material recycling. Through the hot runner connection pipe 3, precise docking between the injection molding machine 1 and the recycling equipment is achieved, conveying the extruded clumps of rubber material from the barrel 11 to the forming mold device 4, preventing spillage or contamination during transfer. The forming mold device 4 breaks down the rubber material into regular rubber strips, solving the problem of inconsistent sizes in traditional manual forming. The conveying device 5 replaces manual transfer, reducing contact between the rubber material and external impurities while achieving continuous conveying. The cold water tank and pelletizing table 7 work together to cool and shape the rubber strips, which are then collected centrally through the recycling box 8. The entire process requires no manual intervention, significantly improving recycling efficiency and reducing labor costs. Furthermore, the recycled rubber granules are regular in shape and can be directly reused as "secondary material," reducing material waste. The barrel 11 rubber material recycling equipment is movable, allowing it to provide rubber material recycling functionality for multiple injection molding machines 1, avoiding the need for redundant rubber material recycling equipment for multiple injection molding machines 1.

[0022] like Figures 2 to 5 The illustrated embodiment 2 shows a barrel 11 rubber material recycling device. In this embodiment, the device of embodiment 1 is placed on a movable platform 2, making the movement of the barrel 11 rubber material recycling device more convenient. The forming mold device 4, conveying device 5, cooling water tank 6, pelletizing table 7, and recycling box 8 are installed on the movable platform 2. The bottom surface of the movable platform 2 is provided with rollers, making the movable platform 2 slidable. This allows the barrel 11 rubber material recycling device to be easily pushed to any injection molding machine 1 for rubber material recycling operations. The barrel 11 rubber material recycling device can more conveniently provide barrel 11 rubber material recycling function for multiple injection molding machines 1.

[0023] In a preferred embodiment, the activity platform 2 has an observation window 21 on its side. The observation window 21 allows for convenient observation of the recycling process of the recycling equipment and also facilitates handling of various accidents during the recycling process.

[0024] like Figure 1 and, Figure 2 , Figure 4 as well as Figure 5 As shown, it also includes a fixing frame 9, which has a mounting surface 91. The lower side of the mounting surface 91 forms a receiving cavity for accommodating the conveying device 5. The shaping mold device 4 is fixed on the mounting surface 91, and the discharge port of the shaping mold device 4 is vertically aligned with the transmission device. The discharge port and the conveying device 5 can be precisely aligned, and the rubber strip can be naturally aligned with the conveying device 5 under the action of gravity. At the same time, it is also convenient for the operator to guide the rubber strip into the conveying device 5 for transmission.

[0025] like Figure 1 and, Figure 2 , Figure 4 as well as Figure 5 As shown, the fixing frame 9 faces at least one opening, the conveying device 5 conveys the rubber strip out from the opening direction, and the cooling water tank 6, the pelletizing table 7 and the recycling box 8 are arranged in sequence on the path of the rubber strip being conveyed out, forming a continuous process of "conveying-cooling-cutting-collecting".

[0026] like Figure 1 and, Figure 2 , Figure 4 as well as Figure 5 As shown, the forming mold device 4 includes an extrusion device and a discharge mold 42. The discharge port is set on the discharge mold 42. The extrusion device squeezes the rubber material, causing the rubber material to be extruded from the discharge port and decomposed into multiple rubber strips. The extrusion device can be a conventional screw extrusion device in the art. The screw extrusion device uniformly extrudes the lumpy rubber material from the discharge port and decomposes it into multiple rubber strips. The conveying device 5 can be a conventional high-temperature resistant conveyor belt in the art, combined with a roller assembly to convey the rubber strips. The high-temperature resistant conveyor belt is such as silicone, Teflon, or glass fiber composite belt. The roller assembly usually includes a drive roller, a driven roller, and a tensioning assembly. Alternatively, a conventional vacuum adsorption conveying device 5 in the art can be used to adsorb the rubber strips onto the high-temperature resistant conveyor belt through negative pressure.

[0027] The pelletizing table 7 is used to receive the rubber strips after they have been cooled and solidified by the cold water tank 6, and to cut them into granular rubber pellets. The pelletizing table 7 uses conventional plastic pelletizing equipment in the art, such as a rotary pelletizer, flat-blade pelletizer, or rotary pelletizer. It mainly consists of a drive motor, cutting blades, a feeding guide mechanism, and a frame. The cutting blades are connected to the drive motor for high-speed rotary cutting; the feeding guide mechanism precisely guides the rubber strips into the cutting area, ensuring a stable cutting position. It should be noted that the specific structure, principle, and control method of the forming mold device 4, the conveying device 5, and the pelletizing table 7 are all existing technologies and are not improvements of this invention. This invention only utilizes their mature forming, conveying, and pelletizing functions, working together to achieve automated cutting and collection of the rubber strips.

[0028] like Figure 1 and, Figure 2 , Figure 4 as well as Figure 5 As shown, the cooling water tank 6 is elongated, and multiple supporting beams 61 are arranged along the length of the cooling water tank 6. The elongated cooling water tank 6 can ensure that the rubber strip can be cooled sufficiently, and the multiple supporting beams 61 can support the rubber strip and prevent the rubber strip from deforming too much during the cooling process in the cooling water tank 6, which would affect the cutting of the rubber strip by the pelletizing table 7.

[0029] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
