Description

Technical Field

[0001] The invention relates to the technical field of waste crushing, in particular to a waste recycling and crushing device used for sealing ring production. Background Art

[0002] A sealing ring is an annular rubber ring with a circular cross-section, primarily used to prevent leakage of liquid and gaseous media in mechanical components under static conditions. In some cases, it can also be used as a dynamic sealing element for axial reciprocating motion and low-speed rotational motion. Different materials can be selected to suit different conditions. Rubber rings are generally chosen with large-cross-section O-rings. Under the same clearance conditions, the volume of the rubber ring squeezed into the gap should be less than the maximum allowable value. For different types of fixed or dynamic sealing applications, rubber rings provide designers with an effective and economical sealing element. In order to reduce environmental pollution, the waste generated during the production of sealing rings needs to be crushed and then recycled.

[0003] Existing devices are unable to cool the crushing head. The crushing head will melt the rubber waste at high temperatures, causing the rubber to adhere to the blades and thus affecting the crushing effect of the crushing head. At the same time, the service life of the crushing head at high temperatures is shortened. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides: a waste recycling and pulverizing device for sealing ring production, comprising a recycling frame for collecting pulverized waste, and a discharge frame arranged on one side of the recycling frame, a feeding port being formed at the top of the recycling frame, and a driving motor being installed on the outside of the recycling frame;

[0005] A limiting plate having a special-shaped plate structure and an arc-shaped limiting plate provided on one side of the limiting plate, wherein a crushing device and an extrusion device are respectively installed on the side of the limiting plate close to the arc-shaped limiting plate;

[0006] The crushing device also includes a crushing drum, a cooling pipe and an arc-shaped crushing head. The crushing drum is arranged on one side of the limit plate. The driving motor is turned on to drive the crushing drum to rotate, and the waste generated during the production of the sealing ring is poured into the top of the crushing device from the feed port. When the crushing drum rotates, it drives the arc-shaped crushing head to cut and crush the incoming waste. The crushed waste falls into the recycling box for collection and recycling. When the arc-shaped crushing head cuts and crushes the waste, the arc-shaped crushing head will generate high heat when it rubs against the rubber waste for a long time. The air inlet pipe is connected to the external cooling equipment, and the external cooling gas is sent into the cooling pipe through the air inlet pipe. The cooling gas is blown to the arc-shaped crushing head from the air outlet, which can cool the arc-shaped crushing head, effectively preventing the problem of melting the rubber waste under high temperature of the arc-shaped crushing head, and preventing the rubber from adhering to the blade, thereby avoiding affecting the crushing effect of the arc-shaped crushing head.

[0007] The extrusion device further comprises an arc-shaped extrusion plate, a rotating motor and a scraping device. The rotating motor is arranged on a side of the recovery frame close to the driving motor and is fixedly connected to the recovery frame.

[0008] Preferably, the discharge frame is connected to the recovery frame, and the limit plates are provided in two groups and are symmetrically distributed inside the recovery frame. One side of the limit plate is fixedly connected to the inner wall of the recovery frame, and the top of the limit plate passes through the feed port and is fixedly connected to the feed port.

[0009] Preferably, both ends of the arc-shaped limiting plate are fixedly connected to the limiting plate, and the top of the arc-shaped limiting plate passes through the feed port and is fixedly connected to the feed port.

[0010] Preferably, the crushing device also includes a rotating shaft, arc-shaped openings are evenly opened on the outside of the crushing cylinder, air outlet holes are opened on the outside of the cooling pipe, and an annular heat-conducting ring is installed on the inner wall of the cooling pipe. The outer side of the annular heat-conducting ring is fixedly connected to the arc-shaped crushing head through a metal heat-conducting plate. The end of the cooling pipe away from the rotating shaft passes through the limit plate and the recovery frame and is connected to the air inlet pipe. The gas passing through the inside of the cooling pipe cools the annular heat-conducting ring. The cooled annular heat-conducting ring transfers the temperature from the metal heat-conducting plate to the arc-shaped crushing head, and can exchange heat with the arc-shaped crushing head, thereby improving the cooling efficiency of the arc-shaped crushing head and increasing the service life of the arc-shaped crushing head.

[0011] Preferably, one end of the rotating shaft is fixedly connected to the output end of the driving motor, the end of the rotating shaft away from the driving motor passes through the crushing barrel and is fixedly connected to the end of the cooling pipe, and the end of the rotating shaft close to the cooling pipe passes through the recovery frame and the limit plate and is rotatably connected to the recovery frame and the limit plate through bearings.

[0012] Preferably, the air outlet holes, the annular heat conducting rings and the arc-shaped crushing heads are provided in multiple groups, and the arc-shaped crushing heads correspond to the arc-shaped openings one by one.

[0013] Preferably, the arc-shaped crushing head penetrates and extends to the outside of the arc-shaped opening, and the air inlet pipe is rotatably connected to the cooling pipe through a sealed bearing.

[0014] Preferably, the extrusion device also includes a device port, which is opened on the arc-shaped extrusion plate. The side of the arc-shaped extrusion plate passes through and is rotatably connected to a rotating column through a bearing. The scraping device is arranged on the rotating column at a position at the device port. When the crushing cylinder rotates, the arc-shaped crushing head is driven to rotate. Due to the setting of the arc-shaped extrusion plate, the arc-shaped crushing head squeezes and impacts the waste to one side of the arc-shaped extrusion plate when cutting the waste. The waste abuts against the arc-shaped extrusion plate. As the arc-shaped crushing head continues to rotate, the waste is pressed against one side of the arc-shaped extrusion plate and is continuously crushed and extruded, thereby achieving the purpose of extruding and crushing the material, which is beneficial to improving the efficiency of waste crushing.

[0015] Preferably, both sides of the arc-shaped extrusion plate are fixedly connected to the limit plate, one end of the rotating column is fixedly connected to the output end of the rotating motor, and the end of the rotating column away from the rotating motor is rotatably connected to the limit plate through a bearing, and the device port is provided with multiple groups and staggered with the arc-shaped crushing head.

[0016] Preferably, the scraping device also includes a rotating sleeve, which is sleeved on the rotating column and fixedly connected to the rotating column. The outer side of the rotating sleeve is fixedly connected to an arc-shaped rotating plate. The arc-shaped rotating plates are provided with multiple groups and correspond one to one to the device port. The arc-shaped rotating plate is evenly provided with grooves on one side close to the crushing cylinder. The inside of the groove is rotatably connected to a rotating rod through a rotating seat. The outer side of the rotating rod is sleeved and fixedly connected to a roller. The outer side of the roller is evenly installed with a brush head. Turning on the rotating motor can drive the rotating sleeve to rotate in the device port. As the rotation amplitude of the rotating sleeve changes, the degree of deflection of the arc-shaped rotating plate can be adjusted, thereby changing the distance between the arc-shaped rotating plate and the arc-shaped crushing head. The smaller the distance between the arc-shaped rotating plate and the arc-shaped crushing head, the smaller the waste material can be crushed. Waste materials of different volumes can be crushed, thereby improving the adaptability of the device. At the same time, since the arc-shaped rotating plate and the arc-shaped crushing head are staggered, when the arc-shaped rotating plate is close to the crushing barrel, the crushing barrel can rotate along the roller on the arc-shaped rotating plate, and the roller can scrape off the waste material on the outer wall of the crushing barrel.

[0017] The present invention provides a device for recycling and crushing waste materials used in sealing ring production. It has the following beneficial effects:

[0018] 1. This is a waste recycling and crushing device for sealing ring production. Through the installation of the crushing device, the driving motor is turned on to drive the crushing drum to rotate, and the waste generated during the production of the sealing ring is poured into the top of the crushing device from the feed port. When the crushing drum rotates, it drives the arc-shaped crushing head to cut and crush the incoming waste. The crushed waste falls into the recycling frame for collection and recycling. When the arc-shaped crushing head cuts and crushes the waste, the arc-shaped crushing head will generate high heat when it rubs with the rubber waste for a long time. The air inlet pipe is connected to the external cooling equipment, and the external cooling gas is sent into the cooling pipe through the air inlet pipe. The cooling gas is blown to the arc-shaped crushing head from the air outlet, which can cool the arc-shaped crushing head and effectively prevent the problem of melting the rubber waste at high temperature by the arc-shaped crushing head, and prevent the rubber from adhering to the blade, avoiding affecting the crushing effect of the arc-shaped crushing head.

[0019] 2. This waste recycling and crushing device for sealing ring production, through the installation of an annular heat-conducting ring and a metal heat-conducting plate, cools the annular heat-conducting ring through the gas inside the cooling tube. The cooled annular heat-conducting ring transfers the temperature from the metal heat-conducting plate to the arc-shaped crushing head, and can exchange heat with the arc-shaped crushing head, thereby improving the cooling efficiency of the arc-shaped crushing head and increasing the service life of the arc-shaped crushing head.

[0020] 3. This is a waste recycling and crushing device for sealing ring production. Through the installation of the extrusion device, the arc-shaped crushing head is driven to rotate when the crushing cylinder rotates. Due to the setting of the arc-shaped extrusion plate, the arc-shaped crushing head squeezes the waste to the side of the arc-shaped extrusion plate when cutting the waste. The waste is abutted against the arc-shaped extrusion plate. As the arc-shaped crushing head continues to rotate, the waste is pressed against the side of the arc-shaped extrusion plate and is continuously crushed and squeezed, thereby achieving the purpose of extruding and crushing the material, which is beneficial to improving the efficiency of waste crushing.

[0021] 4. This is a waste recycling and crushing device for sealing ring production. Through the installation of a scraping device and an extrusion device, turning on the rotating motor can drive the rotating sleeve to rotate in the device mouth. As the rotation amplitude of the rotating sleeve changes, the degree of deflection of the arc-shaped rotating plate can be adjusted, thereby changing the distance between the arc-shaped rotating plate and the arc-shaped crushing head. The smaller the distance between the arc-shaped rotating plate and the arc-shaped crushing head, the smaller the waste volume can be crushed. Waste materials of different volumes can be crushed, thereby improving the adaptability of the device. At the same time, since the arc-shaped rotating plate and the arc-shaped crushing head are staggered, when the arc-shaped rotating plate is close to the crushing barrel, the crushing barrel can rotate along the roller on the arc-shaped rotating plate, and the roller can scrape off the waste on the outer wall of the crushing barrel.

[0034] The crushing device 7 further includes a crushing barrel 71, a cooling pipe 72 and an arc-shaped crushing head 73. The crushing barrel 71 is arranged on one side of the limiting plate 5.

[0035] The extrusion device 8 further includes an arc-shaped extrusion plate 81 , a rotating motor 82 and a scraping device 83 . The rotating motor 82 is arranged on a side of the recovery frame 1 close to the drive motor 4 and is fixedly connected to the recovery frame 1 .

[0036] The discharge frame 2 is connected to the recovery frame 1, and two groups of limit plates 5 are provided and symmetrically distributed inside the recovery frame 1. One side of the limit plate 5 is fixedly connected to the inner wall of the recovery frame 1, and the top of the limit plate 5 passes through the feed port 3 and is fixedly connected to the feed port 3.

[0037] Both ends of the arc-shaped limiting plate 6 are fixedly connected to the limiting plate 5 , and the top of the arc-shaped limiting plate 6 passes through the feed port 3 and is fixedly connected to the feed port 3 .

[0038] The crushing device 7 also includes a rotating shaft 74, arc-shaped openings 75 are evenly opened on the outside of the crushing cylinder 71, air outlet holes 76 are opened on the outside of the cooling pipe 72, and an annular heat-conducting ring 77 is installed on the inner wall of the cooling pipe 72. The outer side of the annular heat-conducting ring 77 is fixedly connected to the arc-shaped crushing head 73 through a metal heat-conducting plate 78. The end of the cooling pipe 72 away from the rotating shaft 74 passes through the limit plate 5 and the recovery frame 1 and is connected to the air inlet pipe 79.

[0039] One end of the rotating shaft 74 is fixedly connected to the output end of the driving motor 4, the end of the rotating shaft 74 away from the driving motor 4 passes through the crushing barrel 71 and is fixedly connected to the end of the cooling pipe 72, and the end of the rotating shaft 74 close to the cooling pipe 72 passes through the recovery frame 1 and the limit plate 5 and is rotatably connected to the recovery frame 1 and the limit plate 5 through bearings.

[0040] There are multiple groups of air outlet holes 76 , annular heat conducting rings 77 and arc-shaped crushing heads 73 , and the arc-shaped crushing heads 73 correspond to the arc-shaped openings 75 one by one.

[0041] The arc-shaped crushing head 73 penetrates and extends to the outside of the arc-shaped opening 75, and the air inlet pipe 79 is rotatably connected to the cooling pipe 72 through a sealed bearing.

[0042] During use, the driving motor 4 is turned on to drive the crushing drum 71 to rotate, and the waste generated during the production of the sealing ring is poured into the top of the crushing device 7 from the feed port 3. When the crushing drum 71 rotates, it drives the arc-shaped crushing head 73 to cut and crush the incoming waste. The crushed waste falls into the recycling frame 1 for collection and recycling. When the arc-shaped crushing head 73 cuts and crushes the waste, the arc-shaped crushing head 73 will generate high heat when it rubs with the rubber waste for a long time. The air inlet pipe 79 is connected to the external cooling equipment, and the external cooling gas is sent into the cooling pipe 72 through the air inlet pipe 79. The cooling gas is blown to the arc-shaped crushing head 73 from the air outlet 76, which can cool the arc-shaped crushing head 73 and effectively prevent the arc-shaped crushing head 73 from melting the rubber waste at high temperature, and prevent the rubber from adhering to the blade, thereby avoiding affecting the crushing effect of the arc-shaped crushing head 73.

[0043] At the same time, the gas passing through the inside of the cooling pipe 72 cools the annular heat-conducting ring 77. The cooled annular heat-conducting ring 77 transfers the temperature from the metal heat-conducting plate 78 to the arc-shaped crushing head 73, and can exchange heat with the arc-shaped crushing head 73, thereby improving the cooling efficiency of the arc-shaped crushing head 73 and increasing the service life of the arc-shaped crushing head 73.

[0044] See also Figures 1-8The present invention provides a technical solution: on the basis of embodiment one, the extrusion device 8 also includes a device opening 84, which is opened on the arc-shaped extrusion plate 81. The side of the arc-shaped extrusion plate 81 is penetrated by a rotating column 85 and is rotatably connected to the rotating column 85 through a bearing. The scraping device 83 is arranged on the rotating column 85 at the position of the device opening 84.

[0045] Both sides of the arc-shaped extrusion plate 81 are fixedly connected to the limit plate 5, one end of the rotating column 85 is fixedly connected to the output end of the rotating motor 82, and the end of the rotating column 85 away from the rotating motor 82 is rotatably connected to the limit plate 5 through a bearing. The device port 84 is provided with multiple groups and is staggered with the arc-shaped crushing head 73.

[0046] The scraping device 83 also includes a rotating sleeve 831, which is sleeved on the rotating column 85 and fixedly connected to the rotating column 85. The outer side of the rotating sleeve 831 is fixedly connected to an arc-shaped rotating plate 832. There are multiple groups of arc-shaped rotating plates 832 and they correspond one to one to the device port 84. The arc-shaped rotating plates 832 are evenly provided with grooves 833 on the side close to the crushing cylinder 71. The inside of the groove 833 is rotatably connected to a rotating rod 834 through a rotating seat. The outer side of the rotating rod 834 is sleeved and fixedly connected with a roller 835, and the outer side of the roller 835 is evenly installed with a brush head.

[0047] During use, the rotation of the crushing barrel 71 drives the arc-shaped crushing head 73 to rotate. Due to the setting of the arc-shaped extrusion plate 81, the arc-shaped crushing head 73 squeezes the waste to the side of the arc-shaped extrusion plate 81 when cutting the waste. The waste is against the arc-shaped extrusion plate 81. As the arc-shaped crushing head 73 continues to rotate, the waste is pressed against the side of the arc-shaped extrusion plate 81 and is continuously crushed and squeezed, thereby achieving the purpose of extruding and crushing the material, which is beneficial to improving the efficiency of waste crushing.

[0048] Turning on the rotating motor 82 can drive the rotating sleeve 831 to rotate in the device mouth 84. As the rotation amplitude of the rotating sleeve 831 changes, the degree of deflection of the arc-shaped rotating plate 832 can be adjusted, thereby changing the distance between the arc-shaped rotating plate 832 and the arc-shaped crushing head 73. The smaller the distance between the arc-shaped rotating plate 832 and the arc-shaped crushing head 73, the smaller the waste volume can be crushed. Waste materials of different volumes can be crushed, thereby improving the adaptability of the device. At the same time, since the arc-shaped rotating plate 832 and the arc-shaped crushing head 73 are staggered, when the arc-shaped rotating plate 832 is close to the crushing barrel 71, the crushing barrel 71 can rotate along the roller 835 on the arc-shaped rotating plate 832, and the roller 835 can scrape off the waste on the outer wall of the crushing barrel 71.
