Description

Technical Field

[0001] The utility model belongs to the technical field of rubber roller production, and particularly relates to a screening device for rubber roller production. Background Technique

[0002] The raw materials of rubber rollers usually refer to the original materials used to manufacture rubber rollers. During the production process of rubber rollers, a special screening device for rubber roller production is required to screen the raw materials of rubber rollers, so as to provide raw materials that meet the requirements for the subsequent rubber roller production process.

[0003] The existing screening devices for rubber roller production usually adopt equipment such as vibrating screens and drum screens, and the screening process is carried out by means of dynamic rolling or vibration mechanisms. Although screening and grading screening can be achieved, the sieve holes are easily blocked by raw materials, resulting in a reduction in the fluidity of the sieve holes. Of course, there are also mechanical knocking mechanisms installed on the equipment to gently knock or pat the sieve surface regularly or continuously to effectively shake off the materials stuck in the sieve holes. However, the knocking range is not comprehensive enough during use, and dead corners are likely to appear. Secondly, an additional drive source often needs to be added for driving, resulting in an increase in cost. Content of the Utility Model

[0004] In view of this, the utility model provides a screening device for rubber roller production, which can clean the residues attached in the sieve holes through an anti-blocking structure, prevent the sieve holes from being blocked, ensure that the sieve holes are always in high-efficiency fluidity, realize comprehensive patting of the rotating tube, avoid dead corners, ensure the synchronous and coordinated operation of the screening and anti-blocking mechanisms, realize the operation of one stage driving multiple stages, and reduce costs.

[0005] To solve the above technical problems, the utility model provides a screening device for rubber roller production, including a fixed frame and a feed pipe arranged on the upper side of one end of the fixed frame, and further including a plurality of discharge pipes arranged on the lower side of the fixed frame. It is characterized in that: a rotating tube is rotatably connected to the axis of the inner cavity of the fixed frame, a plurality of sieve holes are arranged on the outer part of the rotating tube, a spiral blade is arranged on the inner arc surface of the rotating tube, one end of the rotating tube close to the feed pipe is the feed end, and one end of the rotating tube far from the feed pipe is the discharge end. An anti-blocking mechanism is further arranged on the upper side of the inner cavity of the fixed frame. That is, the raw materials are screened out through the sieve holes under the action of centrifugal force. Since the aperture of the sieve holes in different chambers increases sequentially along the flow direction of the raw materials, the gradual screening of the raw materials is realized, the separation and collection of raw materials of different specifications are realized, the screening efficiency and accuracy are improved, and raw materials that meet the requirements are provided for the subsequent rubber roller production process.

[0006] The inner cavity of the fixed frame is divided into a plurality of chambers along the axis of the rotating tube, which helps to control the flow direction of the raw materials during the screening process.

[0007] The aperture of the sieve holes in each chamber as a group increases sequentially along the flow direction of the raw materials, that is, multiple levels of screening operations can be carried out simultaneously, and the separation of raw materials of different specifications is realized.

[0008] The anti-blocking mechanism includes a guiding sliding cylinder rotatably connected to the upper side of the inner cavity of the fixed frame. A sliding block is slidably connected to the guiding sliding cylinder in each chamber. A plurality of rubber plates are arranged on the outer arc surface of the sliding block. The plurality of rubber plates are all arranged in cooperation with the rotating pipe. One end of the fixed frame away from the feed pipe is provided with a synchronous driving assembly for driving the rotating pipe and the guiding sliding cylinder to rotate synchronously. That is, the rotating guiding sliding cylinder, sliding block and rubber plates will continuously beat the outside of the rotating pipe, which helps to clean the residues attached in the sieve holes, prevent the sieve holes from being blocked, and ensure that the sieve holes are always in high-efficiency fluidity.

[0009] The anti-blocking mechanism further includes mounting plates respectively arranged at both ends of the fixed frame close to the end of the guiding sliding cylinder. A fixing rod is arranged between the opposite inner side surfaces of the two mounting plates. The fixing rod is located inside the guiding sliding cylinder. A reciprocating wire sleeve is arranged on the fixing rod in each chamber. The reciprocating wire sleeve is threadedly connected to a wire hole arranged at the center of the sliding block located in the same chamber. That is, the sliding block during rotation will be affected by the reciprocating wire sleeve threadedly connected to it and reciprocate along the guiding sliding cylinder, so as to realize the comprehensive beating of the rotating pipe and avoid dead angles.

[0010] The synchronous driving assembly includes a rotating column rotatably connected to one end of the fixed frame away from the feed pipe. A gear is arranged at the end of the rotating column away from the fixed frame. A tooth ring is arranged at the discharge end of the rotating pipe. The tooth ring is meshed and connected with the gear. A motor is arranged at one end of the fixed frame away from the feed pipe. The end of the rotating column away from the fixed frame is fixedly connected to the output shaft of the motor. That is, the rotation of the output shaft of the motor drives the rotating column and the gear on it to rotate synchronously. When the gear rotates, it drives the rotating pipe, sieve holes and spiral fins to rotate synchronously through the tooth ring meshed and connected with it, so as to play an efficient driving role.

[0011] The synchronous driving assembly further includes a pulley I arranged at one end of the rotating column close to the motor. A pulley II is arranged at one end of the guiding sliding cylinder away from the feed pipe. The pulley II and the pulley I are connected by a belt in transmission connection. That is, it ensures the synchronous and coordinated operation of the screening and anti-blocking mechanisms and realizes the operation of one stage driving multiple stages.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. Feed the raw materials for the production of rubber rollers to be screened into the fixed frame through the feed pipe, and then enter the rotating pipe through the feed end of the rotating pipe. As the spiral fins inside the rotating pipe prompt the raw materials to move along the axial direction of the rotating pipe, at the same time, the raw materials are sieved out through the sieve holes under the action of centrifugal force. Since the aperture of the sieve holes in different chambers increases sequentially along the flow direction of the raw materials, the gradual screening of the raw materials is realized, the separation and collection of raw materials of different specifications are achieved, the screening efficiency and accuracy are improved, and raw materials meeting the requirements are provided for the subsequent rubber roller production process. At the same time, the rotating guide sliding cylinder, sliding block and rubber plate will continuously beat the outside of the rotating pipe, which helps to clean the residues attached in the sieve holes, prevent the sieve holes from being blocked, and ensure that the sieve holes are always in high-efficiency fluidity.

[0014] 2. During the rotation process, the sliding block will reciprocate along the guide sliding cylinder under the influence of the reciprocating wire sleeve threadedly connected thereto, so as to realize the comprehensive beating of the rotating pipe and avoid dead corners.

[0015] 3. The rotation of the output shaft of the motor drives the rotating column and the gear and pulley I thereon to rotate synchronously. When the gear rotates, it drives the rotating pipe, sieve holes and spiral fins to rotate synchronously through the tooth ring engaged therewith. At the same time, when the pulley I rotates, it drives the pulley II, guide sliding cylinder, sliding block and rubber plate to rotate synchronously through the belt, so as to ensure the synchronous and coordinated operation of the screening and anti-blocking mechanisms and realize the operation of one level driving multiple levels.

All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model. Figures 1-5 Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of the present utility model.

[0023] As Figures 1-5 shown:

[0024] This embodiment provides a rubber roller production screening device, which includes a fixed frame 100 and a feed pipe arranged on the upper side of one end of the fixed frame 100. The feed pipe is used to convey the raw materials for rubber roller production to be screened. It also includes a plurality of discharge pipes arranged on the lower side of the fixed frame 100. The plurality of discharge pipes are evenly distributed along the axis of the fixed frame 100. The discharge pipes are used to discharge the screened raw materials. Its characteristics are as follows: A rotating pipe 101 is rotatably connected to the central axis of the inner cavity of the fixed frame 100. Ring-shaped rotating grooves for providing rotating support for the rotating pipe 101 are provided at both ends of the central axis of the inner cavity of the fixed frame 100. A plurality of screening holes 102 are provided on the outer surface of the rotating pipe 101. The plurality of screening holes 102 are evenly distributed. A spiral blade 103 is provided on the inner arc surface of the rotating pipe 101. One end of the rotating pipe 101 close to the feed pipe is the feed end, and one end of the rotating pipe 101 far from the feed pipe is the discharge end. An anti-blocking mechanism is also provided on the upper side of the inner cavity of the fixed frame 100.

[0025] The raw materials for rubber roller production to be screened are fed into the fixed frame 100 through the feed pipe, and then enter the rotating pipe 101 through the feed end of the rotating pipe 101. As the spiral blade 103 in the rotating pipe 101 promotes the raw materials to move along the axis of the rotating pipe 101, at the same time, the raw materials are screened out through the screening holes 102 under the action of centrifugal force. Since the aperture diameters of the screening holes 102 in different chambers increase sequentially along the raw material flow direction, the step-by-step screening of the raw materials is realized, the separation and collection of raw materials of different specifications are realized, the screening efficiency and accuracy are improved, and raw materials meeting the requirements are provided for the subsequent rubber roller production process.

[0026] As Figures 1-5 shown, the inner cavity of the fixed frame 100 is divided into a plurality of chambers along the axis of the rotating pipe 101. The plurality of chambers can be regarded as a plurality of independent screening units, which helps to control the flow direction of the raw materials during the screening process.

[0027] As Figures 1-5 shown, the aperture diameters of the screening holes 102 in each chamber as a group increase sequentially along the raw material flow direction. Different sizes of screening holes are provided in each chamber, which can perform multiple levels of screening operations simultaneously and realize the separation of raw materials of different specifications.

[0028] AsFigures 1-4 As shown in the figure, the anti-blocking mechanism includes a guiding sliding cylinder 200 rotatably connected to the upper side of the inner cavity of the fixed frame 100. The guiding sliding cylinder 200 is cylindrical and hollow, and its upper and lower sides are designed with rectangular openings. A sliding block 201 is slidably connected to the guiding sliding cylinder 200 in each chamber. A plurality of rubber plates 202 are arranged on the outer arc surface of the sliding block 201. The plurality of rubber plates 202 are symmetrically distributed. The rubber plates 202 are used to pat the outside of the rotating pipe 101, which helps to clean the residues attached in the sieve holes 102. The plurality of rubber plates 202 are arranged in cooperation with the rotating pipe 101. A synchronous driving assembly is provided at one end of the fixed frame 100 away from the feed pipe for driving the rotating pipe 101 and the guiding sliding cylinder 200 to rotate synchronously.

[0029] The rotating guiding sliding cylinder 200, sliding block 201 and rubber plates 202 will continuously pat the outside of the rotating pipe 101, which helps to clean the residues attached in the sieve holes 102, prevent the sieve holes 102 from being blocked, and ensure that the sieve holes 102 are always in high-efficiency fluidity.

[0030] As Figures 1-4 shown in the figure, the anti-blocking mechanism further includes mounting plates 203 respectively arranged at both ends of the fixed frame 100 close to the ends of the guiding sliding cylinder 200. A fixing rod 204 is arranged between the opposite inner side surfaces of the two mounting plates 203. The mounting plates 203 are used to provide fixed support for the fixing rod 204. The fixing rod 204 is located inside the guiding sliding cylinder 200. A reciprocating wire sleeve 205 is arranged on the fixing rod 204 in each chamber. The reciprocating wire sleeves 205 are evenly distributed along the axis of the fixing rod 204. The fixing rod 204 is used to provide fixed support for the reciprocating wire sleeves 205. The reciprocating wire sleeves 205 are respectively threadedly connected to the threaded holes arranged at the centers of the sliding blocks 201 in the same chamber.

[0031] During the rotation process, the sliding block 201 will be affected by the reciprocating wire sleeve 205 threadedly connected to it and reciprocate along the guiding sliding cylinder 200, so as to realize the comprehensive patting of the rotating pipe 101 and avoid dead angles.

[0032] As Figures 1-5As shown, the synchronous drive assembly includes a rotating column 300 rotatably connected to the end of the fixed frame 100 away from the feed pipe. A rotating hole for providing rotational support for the rotating column 300 is provided at the end of the fixed frame 100 away from the feed pipe. A gear 301 is provided at the end of the rotating column 300 away from the fixed frame 100. A toothed ring 302 is provided at the discharge end of the rotating pipe 101. The toothed ring 302 is meshed and connected with the gear 301. When the rotating column 300 rotates, the gear 301 and the first pulley 304 on it rotate synchronously. When the gear 301 rotates, it drives the rotating pipe 101, the sieve holes 102 and the spiral blades 103 to rotate synchronously through the meshed toothed ring 302. A motor 303 is provided at the end of the fixed frame 100 away from the feed pipe. The end of the rotating column 300 away from the fixed frame 100 is fixedly connected to the output shaft of the motor 303. The rotation of the output shaft of the motor 303 drives the rotating column 300 and the gear 301 on it to rotate synchronously.

[0033] The rotation of the output shaft of the motor 303 drives the rotating column 300 and the gear 301 on it to rotate synchronously. When the gear 301 rotates, it drives the rotating pipe 101, the sieve holes 102 and the spiral blades 103 to rotate synchronously through the meshed toothed ring 302, thus playing an efficient driving role.

[0034] As Figures 1-5 shown, the synchronous drive assembly further includes a first pulley 304 provided at the end of the rotating column 300 close to the motor 303. A second pulley 305 is provided at the end of the guiding sliding cylinder 200 away from the feed pipe. The second pulley 305 and the first pulley 304 are connected by a belt drive. When the rotating column 300 rotates, the first pulley 304 on it rotates synchronously. When the first pulley 304 rotates, it drives the second pulley 305, the guiding sliding cylinder 200, the sliding block 201 and the rubber plate 202 to rotate synchronously through the belt, thus ensuring the synchronous and coordinated operation of the screening and anti-blocking mechanisms and realizing the operation of driving multiple levels by one level.

[0035] The working principle of a rubber roller production screening device provided by the present utility model is as follows: The rotation of the output shaft of the motor 303 drives the rotation of the rotating column 300, the gear 301 thereon, and the first pulley 304 synchronously. When the gear 301 rotates, it drives the rotating tube 101, the sieve holes 102, and the spiral blades 103 to rotate synchronously through the tooth ring 302 meshed therewith. At the same time, when the first pulley 304 rotates, it drives the second pulley 305, the guiding sliding cylinder 200, the sliding block 201, and the rubber plate 202 to rotate synchronously through the belt, so as to ensure the synchronous and coordinated operation of the screening and anti-blocking mechanisms, and realize the operation of driving multiple levels by one level. After that, the raw materials for rubber roller production to be screened are fed into the fixing frame 100 through the feed pipe, and then enter the rotating tube 101 through the feed end of the rotating tube 101. As the spiral blades 103 in the rotating tube 101 urge the raw materials to move along the axial direction of the rotating tube 101, at the same time, the raw materials are screened out through the sieve holes 102 under the action of centrifugal force. Since the aperture of the sieve holes 102 in different chambers increases sequentially along the raw material flow direction, the gradual screening of the raw materials is realized, and the separation and collection of raw materials of different specifications are achieved, improving the screening efficiency and accuracy, and providing raw materials meeting the requirements for the subsequent rubber roller production process. At the same time, the rotating guiding sliding cylinder 200, the sliding block 201, and the rubber plate 202 will continuously beat the outside of the rotating tube 101, which helps to clean the residues attached in the sieve holes 102 and prevent the sieve holes 102 from being blocked, ensuring that the sieve holes 102 are always in high-efficiency fluidity. At the same time, the sliding block 201 during rotation will be affected by the reciprocating screw sleeve 205 threadedly connected thereto and reciprocate along the guiding sliding cylinder 200, so as to realize the comprehensive beating of the rotating tube 101 and avoid dead angles.

[0036] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0037] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
