Description

Technical Field

[0001] This utility model relates to the field of recycled rubber production technology, and in particular to a recycled rubber refining and pressing device. Background Technology

[0002] In the waste rubber recycling industry, waste rubber is first processed into rubber powder using rubber powder processing equipment, and then the rubber powder is processed into reclaimed rubber using reclaimed rubber processing equipment. This reclaimed rubber can replace some of the raw rubber or be further processed into rubber products to meet market demand.

[0003] Currently, the typical process flow for recycled rubber production equipment is as follows: First, the rubber powder is desulfurized using a desulfurization tank. Then, a "three-machine-one-line" system consisting of two kneaders and one refining unit is used to complete the kneading, refining, and rolling processes of the rubber compound.

[0004] For example, Chinese utility model patent with authorization announcement number "CN205915551U" discloses a refining machine for reclaimed rubber, which includes a refining machine body with two rollers driven by a motor and a lifting machine. The two rollers are horizontally arranged and are shaped like waist drums. The refining machine body is equipped with a circulating water cooling device, which includes a water collection tank, a cooling water tank, an inlet pipe, an outlet pipe, and an outlet drain. The rollers are hollow with one end open. The outlet drain is funnel-shaped and fixedly installed at the opening of the roller, rotating with the roller. The inlet pipe is fixedly installed, with one end connected to the cooling water tank and the other end passing through the center of the funnel shape of the outlet drain and extending into the roller without contacting the roller or the outlet drain. The water collection tank is located below the outlet drain. One end of the outlet pipe is connected to the outlet drain and the other end is connected to the cooling water tank. A booster pump is installed on the inlet pipe.

[0005] However, the above-mentioned "a refining machine for reclaimed rubber" still has the following technical problems in practical applications: In order to ensure the smooth flow of cooling water, both the inlet pipe and the outlet pipe need to be made of rigid pipes and rigidly connected to the cooling water tank and the roller. Although this structure ensures the cooling efficiency of the roller, it restricts the ability to adjust the distance between the two rollers, resulting in the equipment being unable to flexibly produce rubber sheets with different thickness requirements. Summary of the Invention

[0006] In view of this, it is necessary to provide a refining and pressing device for recycled rubber, which can flexibly adjust the roller spacing while ensuring good roller cooling effect, so as to produce rubber sheets with different thickness requirements.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] This utility model provides a refining and pressing device for recycled rubber, including a U-shaped frame, two spacing adjustment components, a drive roller, a driven roller, and two telescopic water tanks. The two vertically opposite walls of the U-shaped frame are provided with receiving slots. The drive roller and the driven roller are both hollow structures, and the ends of the drive roller and the driven roller are provided with through holes communicating with their respective interiors.

[0009] The two pitch adjustment components are respectively located in the two receiving slots. The driving roller and the driven roller both span across the U-shaped frame. The two telescopic water tanks are respectively located on both sides of the U-shaped frame. The ends of the driving roller and the driven roller both pass through the pitch adjustment components and extend into the telescopic water tanks. The driving roller, the driven roller, the pitch adjustment components, and the telescopic water tanks are all rotatably connected. The pitch adjustment components are connected to the receiving slots.

[0010] The spacing adjustment component drives the driven roller to move closer to the driving roller or further away from the driving roller within the receiving groove. At the same time, the driven roller drives the telescopic water tank to extend or shorten to adapt to the spacing between the driven roller and the driving roller. Cooling water in the telescopic water tank flows in or out through the through holes at the ends of the driving roller and the driven roller.

[0011] Preferably, a slide rail is provided along the length of the receiving channel. The spacing adjustment assembly includes a fixed bearing seat and a sliding bearing seat. The sliding bearing seat has a groove adapted to the slide rail of the receiving channel. The fixed bearing seat is fixedly disposed at one end of the receiving channel. The groove of the sliding bearing seat is located on the slide rail of the receiving channel. The end of the driving roller passes through the fixed bearing seat and extends into the telescopic water tank. The driving roller is rotatably connected to the fixed bearing seat. The end of the driven roller passes through the sliding bearing seat and extends into the telescopic water tank. The driven roller is rotatably connected to the sliding bearing seat. The sliding bearing seat drives the driven roller to move closer to the driving roller or away from the driving roller on the slide rail of the receiving channel.

[0012] Preferably, the reclaimed rubber refining and tableting device further includes two adjustment drive components, which are respectively located on two vertical sections of the U-shaped frame. The adjustment drive components are disposed on one end of the U-shaped frame near the sliding bearing seat, so that the output end of the adjustment drive component passes through the side wall of the U-shaped frame and extends into the receiving groove to connect with the sliding bearing seat. The adjustment drive component is used to drive the sliding bearing seat to slide along the slide rail of the receiving groove.

[0013] Preferably, the telescopic water tank includes a first tank body, a second tank body, and a bellows connector. The open ends of the first tank body and the second tank body are directly opposite each other. The two ends of the bellows connector are respectively sealed to the open ends of the first tank body and the second tank body, so that a telescopic sealed cavity is formed inside the bellows connector. The end of the driving roller extends into the first tank body through the spacing adjustment component, and the driving roller is rotatably connected to the first tank body. The end of the driven roller extends into the second tank body through the spacing adjustment component, and the driven roller is rotatably connected to the second tank body. The driven roller drives the bellows connector to extend or shorten through the second tank body to adapt to the spacing between the driven roller and the driving roller.

[0014] Preferably, the reclaimed rubber refining and tableting device further includes a cooling water circulation assembly, which includes a water collection tank, an inlet pipe, a drain pipe, and a centrifugal pump. The water collection tank is located at the bottom of the U-shaped frame. One end of the inlet pipe and the drain pipe are both connected to the water collection tank. The other end of the inlet pipe is connected to the first body of one of the telescopic water tanks, and the other end of the drain pipe is connected to the first body of the other telescopic water tank. The centrifugal pump is mounted on the inlet pipe.

[0015] Preferably, multiple temperature-conducting plates are fixedly provided on the inner walls of both the driving roller and the driven roller, and the multiple temperature-conducting plates are arranged in an array in the inner cavities of the driving roller and the driven roller.

[0016] Preferably, both the driving roller and the driven roller have multiple through holes at their ends that communicate with their interiors, and the multiple through holes are arranged in an array at the ends of the driving roller and the driven roller.

[0017] Preferably, the reclaimed rubber refining and pressing device further includes two scrapers, both of which are arranged horizontally within the U-shaped frame. One scraper is located below the drive roller, and the other scraper is located below the driven roller. The scrapers are used to scrape off residual rubber material from the surface of the drive roller or the driven roller.

[0018] Preferably, the reclaimed rubber refining and pressing device further includes a rubber powder recovery component, which includes a screening and conveying section and a recovery trough. The screening and conveying section has a plurality of perforations on its conveying surface. The screening and conveying section is located at the bottom of the U-shaped frame, and the recovery trough is located below the screening and conveying section. The screening and conveying section is used to convey the rubber sheet extruded by the driving roller and the driven roller, and to vibrate and screen out the rubber powder particles on the rubber sheet. The recovery trough is used to receive the rubber powder particles falling through the perforations.

[0019] Preferably, the U-shaped frame is further provided with two baffles, which are located above the driving roller and the driven roller, and the two baffles are respectively inserted into the gaps at both ends of the driving roller and the driven roller to prevent lateral leakage of rubber raw materials.

[0020] As can be seen from the above technical solution, the reclaimed rubber refining and pressing device provided by this utility model can adjust the distance between the active roller and the driven roller by driving the distance adjustment component to move along the receiving groove of the U-shaped frame. This causes the distance adjustment component to drive the driven roller to move closer to the active roller or further away from the active roller within the receiving groove. During this process, the telescopic water tank will extend or shorten accordingly with the movement of the driven roller to adapt to the change in roller distance. This ensures that the cooling water in the telescopic water tank can always flow in or out through the through holes at the ends of the active roller and the driven roller to cool the active roller and the driven roller, thereby flexibly producing rubber sheets with different thickness requirements.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please refer to Figures 1 to 10 The present invention provides a reclaimed rubber refining and pressing device 10, including a U-shaped frame 110, two spacing adjustment components 120, a drive roller 130, a driven roller 140, and two telescopic water tanks 150. The two vertically opposite walls of the U-shaped frame 110 are provided with receiving through slots 111. The drive roller 130 and the driven roller 140 are both hollow structures, and the ends of the drive roller 130 and the driven roller 140 are provided with through holes 131 communicating with their respective interiors.

[0035] Two pitch adjustment components 120 are respectively located in two receiving channels 111. The driving roller 130 and the driven roller 140 both span across the U-shaped frame 110. Two telescopic water tanks 150 are respectively located on both sides of the U-shaped frame 110. The ends of the driving roller 130 and the driven roller 140 both pass through the pitch adjustment components 120 and extend into the telescopic water tank 150. The driving roller 130, the driven roller 140, the pitch adjustment components 120, and the telescopic water tank 150 are all rotatably connected. The pitch adjustment components 120 are connected to the receiving channels 111.

[0036] The spacing adjustment component 120 drives the driven roller 140 to move closer to the driving roller 130 or further away from the driving roller 130 within the receiving groove 111. At the same time, the driven roller 140 drives the telescopic water tank 150 to extend or shorten to adapt to the spacing between the driven roller 140 and the driving roller 130. The cooling water in the telescopic water tank 150 flows in or out through the through hole 131 at the end of the driving roller 130 and the driven roller 140.

[0037] Specifically, when adjusting the distance between the drive roller 130 and the driven roller 140, the present invention can drive the distance adjustment component 120 to move along the receiving groove 111 of the U-shaped frame 110, causing the distance adjustment component 120 to drive the driven roller 130 to move closer to or further away from the drive roller 130 within the receiving groove 111. During this process, the telescopic water tank 150 will extend or shorten accordingly with the movement of the driven roller 140 to adapt to the change in roller distance, ensuring that the cooling water in the telescopic water tank 150 can always flow in or out through the through holes 131 at the ends of the drive roller 130 and the driven roller 140 to cool the drive roller 130 and the driven roller 140, thereby flexibly producing rubber sheets with different thickness requirements.

[0038] Furthermore, to ensure that the driving roller 130 and the driven roller 140 do not skew during the spacing adjustment process, each receiving groove 111 is provided with a slide rail along its length. Each spacing adjustment assembly 120 includes a fixed bearing seat 121 and a sliding bearing seat 122. The sliding bearing seat 122 has a groove that matches the slide rail of the receiving groove 111. The fixed bearing seat 121 is fixedly disposed at one end of the receiving groove 111, and the groove of the sliding bearing seat 122 is located in the receiving groove 111. On the slide rail, the end of the drive roller 130 extends into the telescopic water tank 150 through the fixed bearing seat 121, and the drive roller 130 is rotatably connected to the fixed bearing seat 121. The end of the driven roller 140 extends into the telescopic water tank 150 through the sliding bearing seat 122, and the driven roller 140 is rotatably connected to the sliding bearing seat 122. The sliding bearing seat 122 drives the driven roller 140 to move closer to the drive roller 130 or away from the drive roller 130 on the slide rail that accommodates the through groove 111.

[0039] Furthermore, to facilitate the movement of the sliding bearing seat 122 along the slide rail of the receiving groove 111 towards or away from the drive roller 130, thereby reducing the labor intensity of the workers, the reclaimed rubber refining and pressing device 10 also includes two adjusting drive components 160. The two adjusting drive components 160 are respectively located on two vertical sections of the U-shaped frame 110, and the adjusting drive components 160 are set at one end of the U-shaped frame 110 near the sliding bearing seat 122, so that the output end of the adjusting drive component 160 passes through the side wall of the U-shaped frame 110 and extends into the receiving groove 111 to connect with the sliding bearing seat 122, so that the sliding bearing seat 122 can be driven to slide along the slide rail of the receiving groove 111 by the adjusting drive components 160.

[0040] In a preferred embodiment, each adjustment drive assembly 160 includes a rocker wheel 161, a lifting mechanism 162, and a push rod 163. The rocker wheel 161 is connected to the input end of the lifting mechanism 162, and the output end of the lifting mechanism 162 is connected to one end of the push rod 163. The other end of the push rod 163 passes through the side wall of the U-shaped frame 110 and is detachably connected to the side of the sliding bearing seat 122 via a flange. When the operator rotates the rocker wheel 161, the power is amplified by the lifting mechanism 162 and drives the push rod 163 to move linearly, thereby directly pushing the sliding bearing seat 122 to move along the slide rail of the receiving groove 111 towards the direction closer to the drive roller 130 or away from the drive roller 130.

[0041] Furthermore, the telescopic water tank 150 includes a first housing 151, a second housing 152, and a bellows connector 153. The open end of the first housing 151 is directly opposite to the open end of the second housing 152. Both ends of the bellows connector 153 are respectively sealed to the open ends of the first housing 151 and the second housing 152, so that a telescopic sealed cavity is formed inside the bellows connector 153. The end of the drive roller 130 extends into the first housing 151 through the fixed bearing seat 121, and the drive roller 130 is rotatably connected to the first housing 151. The end of the driven roller 140 extends into the second housing 152 through the sliding bearing seat 122, and the driven roller 140 is rotatably connected to the second housing 152. The driven roller 140 drives the bellows connector 153 to extend or shorten through the second housing 152 to adapt to the distance between the driven roller 140 and the drive roller 130.

[0042] Specifically, the end of the drive roller 130 passes through the fixed bearing seat 121 and the two opposite side walls of the first housing 151 in sequence, and is supported on the two side walls of the first housing 151 by a pair of bearings. The outer side of the pair of bearings is equipped with a sealing ring, and the shaft end of the drive roller 130 is respectively secured to the two sides of the pair of bearings by a pair of retaining rings to axially position the drive roller 130, ensuring that the through hole 131 at the end of the drive roller 130 is always located inside the first housing 151, thereby ensuring that the drive roller 130 rotates flexibly while effectively preventing the leakage of cooling water.

[0043] Similarly, the end of the driven roller 140 passes through the sliding bearing seat 122 and the two opposite side walls of the second housing 152 in sequence, and is supported on the two side walls of the second housing 152 by a pair of bearings. The outer side of the pair of bearings is equipped with a sealing ring, and the shaft end of the driven roller 140 is respectively secured to the two sides of the pair of bearings by a pair of retaining rings to axially position the driven roller 140, ensuring that the through hole 131 at the end of the driven roller 140 is always located inside the second housing 152, thereby ensuring that the driven roller 140 rotates flexibly while effectively preventing the leakage of cooling water.

[0044] Furthermore, to improve the cooling efficiency of the driving roller 130 and the driven roller 140, the reclaimed rubber refining and pressing device 10 also includes a cooling water circulation assembly 170. The cooling water circulation assembly 170 includes a water collection tank 171, an inlet pipe 172, a drain pipe 173, and a centrifugal pump 174. The water collection tank 171 is located at the bottom of the U-shaped frame 110. One end of the inlet pipe 172 and the drain pipe 173 are both connected to the water collection tank 171. The other end of the inlet pipe 172 is connected to the first housing 151 of one of the telescopic water tanks 150. The other end of the drain pipe 173 is connected to the first housing 151 of the other telescopic water tank 150. The centrifugal pump 174 is installed on the inlet pipe 172. The specific circulation path of the cooling water is as follows: the centrifugal pump 174 circulates the water from the water collection tank... Cooling water in 171 is pumped into the first chamber 151 of a telescopic water tank 150 via inlet pipe 172. Driven by centrifugal pump 174, the cooling water flows into the interior of the active roller 130 and driven roller 140 through the through holes 131 at their ends for cooling. Then it flows out from the through hole 131 at the other end and enters the first chamber 151 of another telescopic water tank 150. Finally, the cooling water flows back to the collection tank 171 through drain pipe 173 under the action of gravity. In this way, without affecting the adjustment of the spacing between the active roller 130 and driven roller 140, continuous heat dissipation can be provided for the active roller 130 and driven roller 140 through circulating water flow, and the working temperature of the active roller 130 and driven roller 140 can be precisely controlled to ensure the continuity of rubber sheet production.

[0045] Furthermore, multiple temperature-conducting plates 132 are fixedly provided on the inner walls of both the driving roller 130 and the driven roller 140, and the multiple temperature-conducting plates 132 are arranged in an array in the inner cavity of the driving roller 130 and the driven roller 140. Compared with smooth rollers, the temperature-conducting plates 132 can increase the contact area between the cooling water flow and the driving roller 130 and the driven roller 140, providing a heat exchange path for the efficient transfer of heat from the roller wall to the cooling water.

[0046] Furthermore, both the drive roller 130 and the driven roller 140 have multiple through holes 131 at their ends that communicate with their interiors. These through holes 131 are arranged in an array at the ends of the drive roller 130 and the driven roller 140. This not only ensures that sufficient cooling water flows into or out of the drive roller 130 and the driven roller 140, but also ensures that even if some through holes 131 become blocked, the remaining through holes 131 can still maintain the necessary flow of cooling water, thereby improving the stability and fault tolerance of the cooling process.

[0047] Furthermore, since rubber residue is easily left on the surfaces of the active roller 130 and the driven roller during operation, if it is not removed in time, the residual rubber will be pressed into the new material in subsequent processing, resulting in defects such as pitting and impurities on the surface of the rubber sheet, which seriously affects the smoothness and flatness of the rubber sheet surface. The reclaimed rubber refining and pressing device 10 also includes two scrapers 180, both of which are horizontally arranged in the U-shaped frame 110. One scraper 180 is located below the active roller 130, and the other scraper 180 is located below the driven roller 140. The scrapers 180 are used to scrape off the residual rubber on the surface of the active roller 130 or the driven roller 140.

[0048] Specifically, one of the scrapers 180 includes a rocker arm 181, a blade 182, a telescopic cylinder 183, and a support rod 184. The rocker arm 181 is rotatably connected to the vertically opposite inner walls of the U-shaped frame 110 via a pair of square bearing seats at both ends, and the rocker arm 181 is located below the lower roller surface of the drive roller 130. The blade 182 is detachably mounted on the rocker arm 181 by bolts, and the blade face of the blade 182 is tangent to the lower roller surface of the drive roller 130. The fixed end of the support rod 184 is connected to the inner wall of the U-shaped frame 110, and the free end of the support rod 184... Extending above the rocker arm 181, the top of the telescopic cylinder 183 is rotatably connected to the free end of the support rod 184. The output end of the telescopic cylinder 183 is rotatably connected to the rocker arm 181 via a pin, so that the telescopic cylinder 183 drives the rocker arm 181 to rotate axially around its own axis, causing the rocker arm 181 to drive the blade surface of the cutter 182 to adhere to or detach from the lower roller surface of the active roller 130, so as to scrape off the residual adhesive on the surface of the active roller 130. The structure and working principle of the other scraper 180 are the same, and it acts on the driven roller 140, which will not be described in detail here.

[0049] Furthermore, the reclaimed rubber refining and pressing device 10 also includes a rubber powder recovery component 190. The rubber powder recovery component 190 includes a screening and conveying section 191 and a recovery trough 192. The screening and conveying section 191 has a plurality of holes 1911 on its conveying surface. The screening and conveying section 191 is located at the bottom of the U-shaped frame 110. The recovery trough 192 is located below the screening and conveying section 191. The screening and conveying section 191 is used to convey the rubber sheet extruded by the drive roller 130 and the driven roller 140 and vibrate to screen out the rubber powder particles on the rubber sheet. The recovery trough 192 is used to receive the rubber powder particles falling through the holes 1911.

[0050] Specifically, the screening and conveying unit 191 includes a conveying frame 1912, two support rollers 1913, a conveyor belt 1914, a drive motor 1915, and several electromagnet vibrators 1916. The conveyor belt 1914 has several perforations 1911 arranged in an array. The two support rollers 1913 are rotatably mounted at both ends of the conveying frame 1912. The conveyor belt 1914 wraps around the two support rollers 1913 to form a closed conveying loop. The drive motor 1915 is installed at one end of the conveying frame 1912, and the output end of the drive motor 1915 is connected to its... A support roller 193 is connected at its shaft center so that the drive motor 1915 drives the support roller 193 to rotate. The support roller 193 drives the conveyor belt 1914 to circulate and transport the material. Several electromagnet vibrators 1916 are installed inside the conveyor frame 1912. The electromagnet vibrators 1916 are used to vibrate the conveyor belt 1914 so that the conveyor belt 1914 vibrates. During the process of conveying the rubber sheet, the conveyor belt 1914 vibrates and screens out the rubber powder particles on the rubber sheet. The rubber powder particles fall into the recycling tank 192 through the leakage hole 1911 for collection and reuse.

[0051] Furthermore, the U-shaped frame 110 is also provided with two baffles 112, which are located above the drive roller 130 and the driven roller 140, and the two baffles 112 are respectively inserted into the gaps at both ends of the drive roller 130 and the driven roller to prevent the rubber raw material from leaking laterally.

[0052] In this invention, the drive roller 130 is driven by a drive device, which uses a conventional combination of a motor and a reducer. The output shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to one end of the drive roller 130.

[0053] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
