Description

Technical Field

[0001] This utility model relates to the field of toy scrap processing technology, and in particular to an automatic mixing device. Background Technology

[0002] Toy scrap processing involves crushing the scraps, mixing the crushed scraps with adhesive in a specific ratio, and then subjecting them to secondary processing operations such as heating and reshaping. This allows the scraps generated during toy production to be reprocessed into toys, thus achieving the recycling of toy scraps. However, in the existing technology, the uniformity of the mixing of scraps and adhesive during the mixing process cannot be effectively controlled. This results in the adhesive and scraps not being able to be effectively molded, leading to poor quality toys formed from the secondary processing of toy scraps that fail to achieve the expected shape and size.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Reference Figure 1This utility model provides an automatic mixing device for secondary processing of toy scraps, including a power supply module; a control module 100, which is electrically connected to the power supply module; and a mixing module 200, which is connected to the control module 100. The mixing module 200 is used to mix the scraps and adhesive materials according to a preset ratio to obtain a mixture. The mixing module 200 includes a mixing tank 210, a proportion controller 220, and a scrap absorption device 230. The proportion controller 220 is located below the mixing tank 210 and the scrap absorption device 230 and is connected to the mixing tank 210. The mixing tank 210 is used to transport the adhesive material to the proportion controller 230. Within the 20-inch container, the edge material absorption device 230 conveys the edge material to the proportional controller; the edge material crushing module 300, connected to the mixing module 200, crushes the toy edge material to a preset size to obtain edge material particles; the adhesive material transport module 400, connected to the mixing module 200, conveys the adhesive material to the mixing tank 210; and the secondary processing module 500, located below and connected to the proportional controller 220, heats and reshapes the mixture. According to the technical solution of this embodiment, the uniformity of the mixture of edge material and adhesive material can be improved, thereby enhancing the quality of the toy formed during secondary processing of the toy edge material.

[0039] It should be noted that the power supply module supplies power to the control module 100, mixing module 200, edge material crushing module 300, and adhesive material conveying module 400 to start the automatic mixing device. Once the automatic mixing device is started, the control module 100 activates the edge material crushing module 300 and the adhesive material conveying module 400 according to their respective models. The edge material crushing module 300 crushes the toy edge material into particles according to a preset size and conveys these particles to the proportional controller 220 of the mixing module 200 via the edge material absorption device 230. The adhesive material conveying module 400 conveys the adhesive material to the mixing tank 210. Under gravity, the edge material particles in the edge material absorption device 230 and the adhesive material in the mixing tank 210 are mixed in the proportional controller 220. The proportional controller 220 precisely controls the mixing ratio of the edge material and the adhesive material, ensuring the consistency and stability of the mixing quality. Furthermore, the mixing process of the automatic mixing device is precisely controlled by the control module 100, reducing manual intervention and improving the efficiency of toy edge material recycling. In addition, the automatic mixing device enables the entire mixing process to be carried out efficiently and quickly through the coordinated work between various modules, meeting the needs of large-scale toy recycling and production.

[0040] Reference Figure 2The mixing tank 210 includes a first cover plate 211 and a first storage cavity 212. The first cover plate 211 is disposed on the upper part of the first storage cavity 212 and connected to the first storage cavity 212. The cross-sectional area of ​​the lower part of the first storage cavity 212 gradually decreases in the direction away from the first cover plate 211. A first connecting pipe 213 is provided at the lower part of the first storage cavity 212. The mixing module 200 also includes a temperature control device 240 and a first fan 250. The temperature control device 240 is electrically connected to the mixing tank 210, the first fan 250 and the control module 100 respectively. The first fan 250 is connected to the mixing tank 210 through the first connecting pipe 213. The temperature control device 240 is used to obtain the real-time temperature signal in the mixing tank. The control module 100 controls the first fan 250 to adjust the real-time temperature in the mixing tank according to the real-time temperature signal until the real-time temperature reaches the preset temperature.

[0041] It should be noted that the mixing tank 210 consists of a first cover plate 211 and a first storage cavity 212. The first cover plate 211 is disposed on the upper part of the first storage cavity 212 and connected to the first storage cavity 212, thereby sealing and protecting the first storage cavity 212. Furthermore, the cross-sectional area of ​​the lower part of the first storage cavity 212 gradually decreases along the direction away from the first cover plate 211, which helps the rubber material move to the proportional controller 220. The temperature control device 240 is electrically connected to the mixing tank 210, the first fan 250 and the control module 100, respectively, and is used to acquire the real-time temperature signal inside the mixing tank 210 and send the real-time temperature signal to the control module 100. When the temperature inside the mixing tank 210 is higher or lower than the preset temperature, the control module 100 controls the first fan 250 to start, stop and adjust the wind speed, thereby realizing the increase or decrease of the temperature inside the mixing tank 210.

[0042] It should be noted that when the internal temperature of the mixing tank 210 is too high, the rubber compound may degrade or melt prematurely, resulting in a deterioration in its performance. Properties such as toughness, wear resistance, and fatigue resistance will significantly decrease. Furthermore, the degraded rubber compound, when processed with edge material particles, can cause defects such as burrs, spots, and dark streaks in the final toy. When the internal temperature of the mixing tank 210 is too low, the rubber compound and edge material particles cannot achieve sufficient plasticization during reshaping. This can lead to excessive viscosity and poor plasticity during mixing and reshaping, thus affecting the final molding effect of the toy. In this embodiment, the control module 100 acquires the real-time temperature signal in the mixing tank 210. Based on this signal, the control module 100 controls the first fan 250 to adjust the real-time temperature inside the mixing tank 210, ensuring that the rubber compound in the mixing tank 210 remains at a stable temperature. This improves the mixing effect of the rubber compound and edge material particles, thereby improving the quality of the toy made from recycled edge material.

[0043] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The proportional controller 220 includes a second storage cavity 221. The upper part of the second storage cavity 221 is provided with a first through hole 222, a second through hole 223, a stirring rod 224, a flow control device, and a third through hole 225. The edge material crushing module 300 is connected to the second storage cavity 221 through the first through hole 222. The mixing tank 210 is connected to the second storage cavity 221 through the second through hole 223. The stirring rod 224 is located in the middle of the second storage cavity 221. Multiple stirring blades 226 are evenly provided on the surface of the stirring rod 224. The third through hole 225 is located at the bottom of the second storage cavity 221. The stirring blades 226 are used to mix the rubber material and the edge material to obtain a mixture. The mixture is transported by the flow control device 226.

[0044] It should be noted that the stirring rod 224 is located in the middle of the second storage chamber 221, and multiple stirring blades 226 are evenly arranged on the surface of the stirring rod 224. These multiple stirring blades 226 ensure that the rubber compound and edge material are fully stirred and mixed during the mixing process, thereby improving the uniformity and quality of the mixture. The flow control device 226 allows for precise control of the mixture's transport process, ensuring a stable supply of the mixture and preventing over- or under-supply, thus improving production efficiency. Furthermore, by adjusting the flow control device 226, the mixing module 200 can adjust the output of the mixture according to actual needs to meet the requirements of different production batches.

[0045] The edge material crushing module 300 is connected to the second storage chamber 221 through the first through hole 222, and the mixing tank 210 is connected to the second storage chamber 221 through the second through hole 223. The modular design allows for easy disassembly and replacement of the various components of the edge material crushing module 300, thereby reducing maintenance costs and time. When a component malfunctions or requires repair, it can be disassembled and handled individually without affecting the normal operation of other components. The third through hole 225 is located at the bottom of the second storage chamber 221, facilitating the discharge and collection of the mixed material. This design not only simplifies the operation process but also improves production efficiency. Furthermore, the third through hole 225 can serve as a channel for cleaning and maintenance, allowing staff to easily clean and inspect the interior of the second storage chamber 221. This automatic mixing device can adapt to crushing and mixing edge materials of different types and particle sizes. By adjusting the speed of the stirring rod 224 and the stirring blade 226, as well as the parameters of the flow control device 226, the mixing requirements of different materials can be met. During the secondary processing of toy scraps, the proportional controller 220 can flexibly adjust the parameters and settings of each component according to actual needs. For example, by changing the speed and stirring time of the stirring rod 224, the uniformity and quality of the mixture can be adjusted; or, by adjusting the output of the flow control device 226, the needs of different production batches can be adapted, thereby improving production efficiency and flexibility.

[0046] Reference Figure 6 and Figure 7 The edge material crushing module 300 includes a crushing unit 310 and a suction unit 320. The suction unit 320 is connected to the crushing unit 310 and the second storage cavity 221, respectively. The crushing unit 310 includes a second housing 311, a drive motor 312 and a first control device 313. The second housing 311 includes a feeding hopper 314, a feeding channel 315 and a crushing channel 316. The feeding channel 315 is connected to the feeding hopper 314 and the crushing channel 316, respectively. The drive motor 312 is connected to the first control unit and the crushing channel 316, respectively. The drive motor 312 is used to crush the edge material entering the crushing channel 316 to obtain crushed edge material.

[0047] It should be noted that the second housing 311 serves as the main structure of the crushing unit 310. The second housing 311 contains a feeding hopper 314, a feeding channel 315, and a crushing channel 316. The coordinated action of the feeding hopper 314, feeding channel 315, and crushing channel 316 ensures that the edge material can be effectively crushed smoothly within the crushing channel 316. The drive motor 312 crushes the edge material entering the crushing channel 316 by rotating the crushing components (such as crushing blades and crushing rollers) within the crushing channel 316. The first control device 313 is used to control the drive motor... The operation of machine 312 includes functions such as starting, stopping, and adjusting speed. The first control device 313 precisely controls the operation of the drive motor 312, achieving precise control of the crushing process. The suction unit 320 is connected to both the crushing unit 310 and the second storage chamber 221. The suction unit 320 sucks the crushed edge material from the crushing channel 316 and transports it to the second storage chamber 221 for subsequent mixing. The crushing unit 310, through the high-speed rotation of the drive motor 312, can quickly crush the edge material entering the crushing channel 316. Simultaneously, the first control device 313 precisely controls the drive motor 312, achieving precise adjustment of the crushed particle size to meet different production needs. The suction unit 320 automatically sucks out the crushed edge material and transports it to the second storage chamber 221, realizing automated production of toy edge material. This not only reduces manual operation costs but also improves the overall automation level of the production line. Furthermore, the edge material crushing module 300, as an independent unit, can be easily connected and combined with other production units. This allows the toy scrap production line to be flexibly adjusted according to actual needs, thereby enhancing production flexibility.

[0048] Reference Figure 7 The material suction unit 320 includes a third storage cavity 321, a second connecting pipe 322, and a third connecting pipe 440323. The upper part of the third storage cavity 321 is provided with a suction mechanism 324. The lower part of the third storage cavity 321 is connected to one end of the second connecting pipe 322, and the other end of the second connecting pipe 322 is connected to the second storage cavity 321. One end of the third connecting pipe 440323 is connected to the lower part of the crushing channel 316, and the other end of the third connecting pipe 440323 is connected to the third storage cavity 321. The cross-sectional area of ​​the lower part of the third storage cavity 321 gradually decreases in the direction away from the suction mechanism 324.

[0049] It should be noted that the design of the automatic suction unit 320 reduces the step of manually feeding the crushed edge material into the mixing tank 210, lowering the frequency and intensity of manual intervention and improving the automation level of the production line. The crushed edge material is evenly fed into the second storage chamber 221 through the suction unit 320, where it is mixed with the adhesive in the proportional controller 220, thereby ensuring the uniformity of the mixture and improving the quality of the final product. The suction unit 320 effectively reduces friction and collision of the edge material during conveying, reducing equipment wear. Simultaneously, the reasonable pipeline layout and the design of the suction mechanism 324 reduce the risk of blockage in the suction unit 320, improving the reliability and durability of the equipment.

[0050] Reference Figure 8 The suction mechanism 324 includes a first placement cavity 325 and a second fan. The second fan is placed on the upper part of the first placement cavity 325, and the first placement cavity 325 is evenly provided with a plurality of ventilation holes 326.

[0051] It should be noted that the multiple ventilation holes 326 evenly distributed on the surface of the first placement chamber 325 help to achieve a uniform airflow distribution. When the second fan is started, the airflow can enter the first placement chamber 325 evenly through each ventilation hole 326, and then be drawn into the suction mechanism 324. Due to differences in internal air pressure, the edge particles output by the crushing mechanism are drawn into the first placement chamber 325. This uniform airflow distribution ensures that the suction mechanism 324 can efficiently absorb air or materials during operation. The design of multiple ventilation holes 326 increases the air intake area of ​​the suction mechanism 324, thereby enhancing its suction power. A larger air intake area means that more airflow can be drawn into the suction mechanism 324. In addition, the second fan generates a certain amount of heat when it is working. The design of the first placement cavity 325 and the ventilation holes 326 on its surface helps to dissipate the heat generated by the fan in a timely manner, preventing the fan from overheating and causing performance degradation or damage, thereby extending the service life of the suction mechanism 324. The design of the ventilation holes 326 can also reduce the noise generated by the suction mechanism 324 when it is working to a certain extent. By increasing the airflow channel and diffusion area, the turbulence and vortex generated by the airflow when passing through the suction mechanism 324 are reduced, thereby reducing the noise level.

[0052] Reference Figure 9The rubber material transport module 400 includes an air pressure regulating unit 410, a storage device 420, a feeding buffer device 430, a fourth connecting pipe 440, and a fifth connecting pipe 450. One end of the fourth connecting pipe 440 is connected to the air pressure regulating unit 410, and the other end of the fourth connecting pipe 440 is connected to the first end of the feeding buffer device 430. One end of the fifth connecting pipe 450 is connected to the second end of the feeding buffer device 430, and the other end of the fifth connecting pipe 450 is connected to the storage device 420. The third end of the feeding buffer device 430 is connected to the mixing module 200. The cross-sectional area of ​​the lower part of the feeding buffer device 430 gradually decreases along the direction close to the mixing module 200.

[0053] It should be noted that the suction generated by the air pressure regulating device draws air from inside the feeding buffer device 430 through the fourth connecting pipe 440. When the pressure inside the feeding buffer device 430 is lower than the external atmospheric pressure, the adhesive material in the mixing tank is drawn in through the fifth connecting pipe 450. When the amount of adhesive material stored in the feeding buffer device 430 reaches a certain level, the adhesive material will slowly fall into the mixing tank 210 under the action of gravity, thereby automatically completing the mixing of adhesive material and toy edge material without manual intervention, thus improving the processing efficiency of toy edge material.

[0054] It should be noted that the adhesive material transport module 400, through the cooperation of the air pressure regulating device and the feeding buffer device 430, achieves automatic suction and conveying of adhesive material, reducing the complexity and labor intensity of manual operation. Operators only need to monitor the operating status of the suction mechanism, eliminating the need for tedious manual operations. Furthermore, the suction mechanism can quickly and continuously convey adhesive material, thereby improving the efficiency of toy recycling.

[0055] Reference Figure 10 The air pressure regulating unit 410 includes a third blower 411, an airflow guide tube 412, a sixth connecting pipe 413, and a second control unit 414. One end of the sixth connecting pipe 413 is connected to the third blower 411, and the other end of the sixth connecting pipe 413 is connected to the airflow guide tube 412. The second control unit 414 is connected to the third blower 411. The second control unit 414 is used to acquire the real-time suction information of the third blower 411 and adjust the suction of the feeding buffer device 430 according to the real-time suction information to adjust the feeding rate of the mixing module 200 in real time.

[0056] It should be noted that the second control unit 414 can acquire the suction information of the third fan 411 in real time. Based on this suction information, the second control unit 414 precisely adjusts the suction of the feeding buffer device 430, thereby controlling the feeding rate of the mixing module 200 in real time. Because the mixing module 200 can adjust its feeding rate in real time, it can adapt to different types of toy scraps and different production needs. By precisely controlling the feeding rate, it ensures that the adhesive material is input into the mixing module 200 at a stable speed, guaranteeing the uniformity and consistency of the mixing process, thus improving the quality of the toys. Real-time adjustment of the feeding rate also avoids unnecessary energy consumption. When the adhesive flow rate is too high, energy consumption is reduced by decreasing the air pressure; conversely, when the adhesive flow rate is too low, production efficiency is increased by increasing the air pressure. The coordinated use of the air pressure regulating unit 410 and the second control unit 414 makes the entire mixing device highly automated. Operators only need to set the parameters, and the equipment can automatically run and complete the mixing task.

[0057] Reference Figure 11 and Figure 12 The automatic mixing device also includes a support frame module 600, which comprises a first support frame unit 610 and a second support frame unit 620. The first support frame unit 610 supports the edge material crushing module 300, and the second support frame unit 620 supports the rubber material transport module 400. The first support frame unit 610 includes a first support plate 611, multiple support columns 612, and multiple support beams 613. The upper side of the first support plate 611 is connected to the crushing module, one end of each of the multiple support columns 612 is connected to the lower side of the first support plate 611, and the other end of each of the multiple support columns 612 is connected to the support beams 613. The second support frame unit 620 includes a base plate 621, a second support plate 622, a third support plate 623, a fourth support plate 624, a fifth support plate 625, a sixth support plate 626, and a seventh support plate 627. One side of the support plate 622 and the third support plate 623 are connected to the base plate 621. The other side of the second support plate 622 is connected to the first side of the fourth support plate 624. The other side of the third support plate 623 is connected to the first side of the fifth support plate 625. The sixth support plate 626 is connected to the second side of the fourth support plate 624. The seventh support plate 627 is connected to the second side of the fifth support plate 625. The fan is located between the fourth support plate 624 and the fifth support plate 625. The control unit is connected to the third side of the fourth support plate 624 and the fifth support plate 625 respectively. The airflow guide tube 412 is connected to the inner side of the sixth support plate 626 and the seventh support plate 627 respectively. The first side and the second side of the fourth support plate 624 and the fifth support plate 625 are adjacent to each other. The third side of the fourth support plate 624 and the fifth support plate 625 is opposite to the first side.

[0058] It should be noted that, through the reasonable layout of the support columns 612 and support beams 613, the movable support can provide stable support for the crushing module, ensuring the stability and safety of the edge material crushing module 300 during operation. The movable support allows the edge material crushing module 300 to be easily moved and positioned, improving work efficiency and flexibility. At the same time, the design of the support columns 612 and support beams 613 also plays a role in buffering and shock absorption, further protecting the safe operation of the crushing module.

[0059] It should be noted that the support frame unit consists of a base plate 621 and first support plates 611 to sixth support plates 626, forming a robust frame structure. This improves the stability of the rubber material transport module 400 during operation and helps resist external environmental interference and vibration, ensuring the device remains stable during long-term operation. The fan is positioned between the third support plate 623 and the fourth support plate 624, helping to maximize the efficiency of the third fan 411 and ensuring that airflow passes evenly and efficiently through the airflow guide tube 412. Simultaneously, the airflow guide tube 412, connected to the inner sides of the fifth support plate 625 and the sixth support plate 626, further guides the airflow along a predetermined path, reducing airflow turbulence. The support frame module 600 is designed for ease of installation and maintenance; the connections between components are simple and straightforward, facilitating disassembly and reassembly. This allows staff to operate the equipment easily during installation, commissioning, and routine maintenance, reducing work difficulty and time costs. Due to the flexible and highly adjustable structural design of the support frame module 600, it can adapt to the needs of air pressure regulating devices of different sizes and types. Whether it is a small toy suction mechanism or a large industrial automation equipment, the specific suction requirements can be met by adjusting the size and layout of the support frame unit.
