Description
Technical Field
[0001] This utility model relates to the field of crushing devices, and in particular to a refrigerator glass door crushing device. Background Technology
[0002] As a key component of refrigerators, the glass door typically consists of an inner foam layer and an outer glass layer. The foam layer primarily serves as insulation, while the glass layer provides protection. These two layers are bonded together using specific processes to ensure the refrigerator's normal functionality. After the refrigerator reaches the end of its lifespan, the recycling of the glass door becomes a crucial part of resource recycling. The foam layer can be processed for use in the production of recycled insulation materials, while the glass layer can be recycled through processes such as melting, achieving both waste reduction and resource recovery.
[0003] However, the large size and unique structure of a refrigerator glass door present significant challenges for direct recycling. On one hand, the glass and foam layers are tightly bonded; without first breaking the glass, effective separation of the two is difficult, leading to low recycling efficiency. On the other hand, manually breaking glass is not only time-consuming, labor-intensive, and inefficient, but also generates sharp glass fragments, posing safety hazards to operators. Therefore, to promote the harmless treatment and efficient recycling of refrigerator glass doors, a specialized refrigerator glass door breaking device is urgently needed. This device should be able to efficiently and safely break the entire refrigerator door into smaller pieces, laying the foundation for precise separation and resource utilization of the foam and glass layers. Utility Model Content
[0004] The main purpose of this invention is to provide a refrigerator glass door breaking device, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A refrigerator glass door breaking device includes a chain conveyor with a support and protection structure fixedly installed at its upper end. A first servo motor is mounted on the chain conveyor. Two sets of rotor breaking structures are mounted on the support and protection structure and connected by a transmission chain. One set of rotor breaking structures is connected to the output shaft of the first servo motor via the transmission chain. Each rotor breaking structure consists of a rotor shaft, a turntable, a chain shaft, and a rotating chain. Several turntables are evenly and fixedly mounted on the rotor shaft. Several chain shafts are fixedly mounted on two adjacent turntables. Several rotating chains are mounted on several chain shafts. A cleaning structure is installed on the support and protection structure and behind the two rotor breaking structures. The cleaning structure consists of a third servo motor and a brush roller, with the brush roller connected to the output shaft of the third servo motor via a transmission belt.
[0006] Preferably, the chain conveyor consists of a conveyor frame, a first frame, a conveyor chain, and a second servo motor. There are two first frames, each fixedly installed at one end of the conveyor frame. The conveyor chain is installed inside the conveyor frame. The second servo motor is fixedly installed on the upper end of one of the first frames. The conveyor chain is connected to the output shaft of the second servo motor through a transmission structure. A movable material box is placed on the lower rear side of the chain conveyor. Several baffles are evenly arranged on the conveyor chain.
[0007] Preferably, the support and protection structure consists of a protective cover structure and a second bracket, with the second bracket fixedly installed at one end of the protective cover structure.
[0008] Preferably, the first servo motor is fixedly mounted on the upper end of another first bracket.
[0009] Preferably, the two rotor shafts on the two sets of rotor crushing structures are connected by a transmission chain. The rotor shaft on one set of rotor crushing structures is connected to the output shaft of the first servo motor by a transmission chain. The rotor shaft on the rotor crushing structure is rotatably mounted on the protective cover structure. The turntable, chain shaft and rotating chain are all located inside the protective cover structure.
[0010] Preferably, the third servo motor on the cleaning structure is fixedly mounted on the upper end of the second bracket, and the brush roller is rotatably mounted inside the protective cover structure.
[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a refrigerator glass door crushing device consisting of a chain conveyor, a support and protection structure, a first servo motor, a rotor crushing structure, and a cleaning structure, the chain conveyor can transport the refrigerator glass door to the rotor crushing structure. The first servo motor drives the rotor crushing structure to operate. Utilizing the synergistic action of the rotor shaft, turntable, chain shaft, and rotating chain, the glass on the refrigerator glass door is efficiently crushed, significantly improving processing efficiency compared to manual crushing. The protective cover structure in the support and protection structure can effectively block the splashing of broken glass during the crushing process, reducing the safety threat to operators, and preventing broken glass from scattering outside the equipment and causing cleaning difficulties. The third servo motor of the cleaning structure drives the brush roller to rotate, which can sweep the broken glass that remains on the foam layer after being crushed by the rotor crushing structure onto the conveyor chain, effectively separating the broken glass from the foam layer. Finally, the conveyor chain transports the broken glass to a movable material box for collection, while the foam layer can be recycled separately, providing convenience for the classification and processing of both.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a refrigerator glass door breaking device includes a chain conveyor 1, a support and protection structure 2 fixedly installed at the upper end of the chain conveyor 1, a first servo motor 3 installed on the chain conveyor 1, and two sets of rotor breaking structures 4 installed on the support and protection structure 2. The two sets of rotor breaking structures 4 are connected by a transmission chain, and one set of rotor breaking structures 4 is connected to the output shaft of the first servo motor 3 through the transmission chain. The rotor breaking structure 4 consists of a rotor shaft 13, a turntable 14, a chain shaft 15, and a rotating chain 16. Several turntables 14 are evenly and fixedly mounted on the rotor shaft 13. Several chain shafts 15 are fixedly mounted on two adjacent turntables 14. Several rotating chains 16 are mounted on several chain shafts 15. A cleaning structure 5 is installed on the support and protection structure 2 and behind the two rotor crushing structures 4. The cleaning structure 5 consists of a third servo motor 17 and a brush roller 18. The brush roller 18 is connected to the output shaft of the third servo motor 17 via a transmission belt. The system is connected by a chain conveyor 1 and a support and protection structure 2. The refrigerator glass door breaking device consists of a protective structure 2, a first servo motor 3, a rotor breaking structure 4, and a cleaning structure 5. The chain conveyor 1 transports the refrigerator glass door to the rotor breaking structure 4, while the first servo motor 3 drives the rotor breaking structure 4 to operate. Utilizing the synergistic action of the rotor shaft 13, turntable 14, chain shaft 15, and rotating chain 16, the glass on the refrigerator glass door is efficiently broken, significantly improving processing efficiency compared to manual breaking. The protective cover structure 11 in the protective structure 2 effectively blocks the splashing of broken glass during the breaking process, reducing the safety threat to operators and preventing broken glass from scattering outside the equipment and causing cleaning difficulties. The third servo motor 17 of the cleaning structure 5 drives the brush roller 18 to rotate, sweeping the broken glass that remains on the foam layer after being broken by the rotor breaking structure 4 onto the conveyor chain 8, effectively separating the broken glass from the foam layer. Finally, the conveyor chain 8 transports the broken glass to the movable material box 10 for collection, while the foam layer can be recycled separately, facilitating the classification and processing of both.
[0016] Specifically, the chain conveyor 1 consists of a conveyor support 6, a first support 7, a conveyor chain plate 8, and a second servo motor 9. There are two first supports 7, each fixedly installed at one end of the conveyor support 6. The conveyor chain plate 8 is installed inside the conveyor support 6. The second servo motor 9 is fixedly installed on the upper end of one of the first supports 7. The conveyor chain plate 8 is connected to the output shaft of the second servo motor 9 via a transmission structure. A movable material box 10 is placed at the lower rear of the chain conveyor 1. Several baffles are evenly arranged on the conveyor chain plate 8. The support and protection structure 2 consists of a protective cover structure 11 and a second support 12. The second support 12 is fixedly installed at one end of the protective cover structure 11. The first servo motor 3 is fixedly installed on the upper end of the other first support 7. Two sets of rotors... Two rotor shafts 13 on the crushing structure 4 are connected by a transmission chain. One set of rotor shafts 13 on the rotor crushing structure 4 is connected to the output shaft of the first servo motor 3 via a transmission chain. The rotor shafts 13 on the rotor crushing structure 4 are rotatably mounted on the protective cover structure 11. The turntable 14, chain shaft 15, and rotating chain 16 are all located inside the protective cover structure 11. The third servo motor 17 on the cleaning structure 5 is fixedly mounted on the upper end of the second bracket 12. The brush roller 18 is rotatably mounted inside the protective cover structure 11. In use, the second servo motor 9 of the chain conveyor 1 is first started. The second servo motor 9 drives the conveyor chain 8 to rotate through the transmission structure. Then, the refrigerator glass door to be crushed is placed on the conveyor chain in front of the protective cover structure 11. At step 8, the refrigerator door must be positioned with the glass side facing upwards, and between two adjacent baffles. The refrigerator door then moves towards the support and protection structure 2 along with the conveyor chain 8. When the refrigerator door enters the protective cover structure 11 of the support and protection structure 2 and reaches the rotor crushing structure 4, the first servo motor 3 drives the rotor shaft 13 of one set of rotor crushing structures 4 to rotate via a transmission chain. Since the rotor shafts 13 of the two sets of rotor crushing structures 4 are connected by a transmission chain, the rotor shaft 13 of the other set of rotor crushing structures 4 also rotates. The rotation of the rotor shaft 13 drives several rotating discs 14 fixedly mounted on it to rotate synchronously. The rotation of the rotating discs 14 then drives the fixedly mounted discs between adjacent rotating discs 14... Several chain shafts 15 rotate, which in turn drive several rotating chains 16 mounted on them to rotate. At this time, the rotating chains 16 impact and break the glass on the refrigerator door. The broken glass is prevented from splashing by the protective cover structure 11. The broken refrigerator door (at this time, the glass is broken, and only the foam layer and a small amount of attached broken glass remain) continues to move backward with the conveyor chain plate 8. When it moves to the cleaning structure 5, the third servo motor 17 drives the brush roller 18 to rotate through the transmission belt. The rotating brush roller 18 sweeps the small amount of broken glass stuck on the foam layer onto the conveyor chain plate 8. At this time, the baffle on the conveyor chain plate 8 can block the foam layer, so that the foam layer is stably conveyed backward by the conveyor chain plate 8 during cleaning.The conveyor chain 8 then continues to operate, transporting the broken glass to a movable material box 10 placed below and behind the conveyor chain 1 for collection. The foam layer can be removed separately for further processing.
[0017] In addition, after the glass on the refrigerator door is broken by the rotor breaking structure 4 and cleaned by the brush roller 18 of the cleaning structure 5, if a small amount of tightly attached broken glass is still attached to the foam layer, the foam layer can be scraped off by a special tool (such as a scraper) when it reaches the end of the chain conveyor 1 with the conveyor chain plate 8. The scraped broken glass can be directly collected into the movable material box 10 placed at the lower rear of the chain conveyor 1. The foam layer after scraping off the broken glass needs to be inspected to confirm that there is no broken glass residue on the surface before it is placed in a special foam recycling container. If a small amount of broken glass remains after one scraping, the scraping operation can be repeated to ensure that the foam layer and broken glass are completely separated so that the broken glass and foam layer can be recycled separately in the future.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
