Description

Technical Field

[0001] The invention belongs to the technical field of power pipe production, and in particular relates to an open mill for power pipe production. Background Art

[0002] The preparation process of power pipe mainly includes batching and refining. The refining needs to be processed by a mixing mill. The rubber raw materials refined by the mixing mill include rubber and additives, including powdered fillers such as talcum powder, carbon black and titanium dioxide, as well as powdered vulcanizing agents such as sulfur and zinc oxide. After the powder is put into the mixing mill, some of the powder cannot be fully bonded and mixed with the rubber, and will inevitably fall under the lower roller.

[0003] In response to the above-mentioned technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent announcement number CN221212362U3. When in use, the powder material that falls during the rubber refining process falls into the collecting hopper and is collected, lifted to a level above the lower pair of rollers by the lifting mechanism, and then led to the rubber material in the gap between the lower pair of rollers through the return pipe. However, during the refining process, due to the squeezing and shearing of the rollers, part of the rubber material will inevitably fall downwards. The rubber material has a certain viscosity, so the rubber material will adhere to the lifting mechanism, resulting in part of the rubber material and powder material being unable to continue to participate in the refining, thereby resulting in the loss of materials. The imbalance in the raw material ratio will lead to a decline in the quality of the raw materials. Summary of the invention

[0004] The purpose of the present invention is to provide an open mill for producing electric power pipes, aiming to solve the technical problem in the prior art that raw materials remain on a collecting component, resulting in an unbalanced raw material ratio that affects the quality of the raw materials.

[0005] The present invention is implemented as follows: an open mill for producing electric power pipes comprises a base, a bracket is fixedly installed on the base, two groups of rollers distributed in parallel are rotatably installed in the base, and two groups of first rotating power members for driving the two groups of rollers to rotate are fixedly installed on the side of the base; A first telescopic member is fixedly installed at both ends of the bracket, a lifting plate is fixedly installed at the output end of the first telescopic member, a collecting bucket is slidably installed on the lifting plate, a moving component that drives the collecting bucket to move is arranged on the lifting plate, the end of the collecting bucket away from the first telescopic member is an opening structure and a baffle is rotatably installed at the opening structure of the collecting bucket, the bottom surface of the collecting bucket is an inclined structure and the end close to the first telescopic member is the higher end, a scraper is slidably installed on the inner bottom surface of the collecting bucket, a power component that drives the scraper to move is arranged on the collecting bucket, a push plate is fixedly installed on the scraper, and when the scraper moves downward, the push plate contacts the baffle and pushes the baffle to rotate.

[0006] Further technical solution: a material box is fixedly installed in the base, the material box is located between the two groups of rollers, and the material box is a vertically penetrating structure.

[0007] Further technical solution: the rotating shaft connecting the baffle and the collecting bucket is located at the upper end of the baffle, and the upper end of the baffle is provided with an inclined structure that facilitates the entry of materials into the collecting bucket.

[0008] Further technical solution: The moving component includes a second rotating power component, which is fixedly mounted on the outer side of the collecting bucket. The second rotating power component drives the gear to rotate, and the gear engages with a rack fixedly mounted on the lifting plate. A groove for installing the rack is provided on the lifting plate, and the racks are distributed along the moving direction of the collecting bucket.

[0009] Further technical solution: The power assembly includes a screw rod, which is rotatably installed in the collecting bucket. The screw rod is parallel to the bottom surface of the collecting bucket. The projection of the screw rod onto the lifting plate is distributed along the moving direction of the collecting bucket. The screw rod is rotatably connected to the scraper, and a third rotating power component that drives the screw rod to rotate is fixedly installed on the outer side of the collecting bucket.

[0010] Further technical solution: A semicircular breakaway plate is fixedly mounted on the lower end of the scraper, and the breakaway plates are distributed along the length direction of the scraper.

[0011] Further technical solution: a support plate is fixedly installed on the scraper plate, and multiple groups of sliding rods are slidably installed on the support plate. The sliding rods penetrate the support plate and a knocking plate is fixedly installed on one end of the sliding rods close to the separation plate. Multiple groups of elastic parts distributed around the sliding rods are fixedly installed on the support plate, and the end of the elastic part away from the support plate is fixedly connected to the knocking plate. An electromagnet is fixedly installed on the support plate, and the electromagnet is energized to adsorb the knocking plate. The knocking plate is made of magnetic material.

[0012] Further technical solution: Multiple groups of linearly spaced elastic wires are fixedly installed on the side of the collecting bucket away from the baffle, the other end of the elastic wires is fixedly connected to the baffle, the multiple groups of elastic wires are distributed in parallel, and the elastic wires are parallel to the bottom surface of the collecting bucket.

[0013] Further technical solution: A horizontal plate is slidably installed at one end of the collecting bucket away from the baffle, and a plurality of push blocks are fixedly installed on the horizontal plate and distributed at intervals with the elastic line. The cross section of the push blocks is a triangular structure, and a second telescopic member that drives the horizontal plate to reciprocate is fixedly installed on the outer side of the collecting bucket.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The falling materials are collected by the collecting bucket, and then the materials in the collecting bucket are re-added. When adding materials, the materials on the bottom of the collecting bucket are pushed downward by the scraper and fall into the material box. When the scraper descends to the lowest end of the collecting bucket, its lower end extends out of the collecting bucket, so that the materials in the collecting bucket can be completely pushed out of the collecting bucket and fall into the material box, reducing the probability of material residue in the collecting bucket, ensuring that additives, rubber and other materials can be fully mixed, ensuring the accuracy of material ratio, and improving the quality of materials. After the collection is completed, the collecting bucket is closed by the lifting plate during the movement process, so as to prevent the collected materials from spilling to the outside during the movement process, further ensuring the accuracy of material ratio.

[0015] 2. When the scraper is scraping the material at the bottom of the collecting bucket, part of the rubber will move along the scraper and contact the separation plate when the scraper moves. Since the separation plate is a semicircular structure, the rubber will move along the separation plate and finally move downward and separate, reducing the possibility of the rubber sticking to the scraper. When the scraper moves to the lower end of the collecting bucket, the lower end of the scraper extends out of the collecting bucket. At this time, the electromagnet is powered on and off several times. After the electromagnet is powered on, it adsorbs the knocking plate. The electromagnet is powered on and off several times to knock on the separation plate several times. Under the action of impact vibration, the scraper is separated from the material adhered to the separation plate, reducing the material residue on the scraper and the separation plate, and further reducing the material residue in the collecting bucket, ensuring that the material participates in mixing and refining, ensuring the correct ratio of raw materials, and improving the quality of raw materials.

[0016] 3. When material falls from the top of the collecting bucket, the powder will pass through the gap between the elastic lines and fall to the bottom of the collecting bucket. At this time, a layer of powder will gradually cover the bottom of the collecting bucket. When the rubber falls from above, the smaller rubber will pass through the gap between the elastic lines and fall to the bottom of the collecting bucket. Since the rubber is smaller and has less inertia, its impact force on the bottom of the collecting bucket is smaller, and thus its bonding force with the collecting bucket is smaller. In addition, since the bottom of the collecting bucket will gradually be covered with a layer of powder, the subsequent rubber will first contact the powder when it falls. The bonding force between the powder and the bottom of the collecting bucket is extremely small and is sandwiched between the rubber and the bottom of the collecting bucket, further reducing the ability of the rubber to bond to the bottom of the collecting bucket, thereby reducing the force between the subsequent scraper and the material when scraping off the material, and reducing the possibility of the scraper bonding to the material.

[0017] 4. When a larger volume of rubber falls, it will contact with multiple groups of elastic lines. Since a larger volume of rubber has a larger weight and a larger inertia, the speed at which the rubber contacts the elastic lines is faster and the impact is greater. Therefore, the larger volume of rubber can be divided into multiple groups of smaller rubber through multiple groups of elastic lines. The separated rubber continues to fall to the bottom of the collecting bucket, and the elastic lines will reduce the falling speed of the rubber when dividing the rubber, further reducing the impact of the rubber on the bottom of the collecting bucket when it falls, and further reducing the ability of the rubber to bond with the collecting bucket, making it easier to clean up the rubber later.

[0018] 5. After the collection of materials is completed, the collecting bucket is pushed out from under the roller, and the lifting plate covers the upper part of the collecting bucket, so that the collecting bucket forms a cavity. The second telescopic member drives the cross plate to move back and forth, and the cross plate drives the push block to move back and forth to make the elastic line vibrate. When the elastic line vibrates, the adjacent elastic lines can collide with each other. Under the action of the vibration, the materials bonded on the elastic lines are separated and fall to the bottom surface of the collecting bucket, further reducing the residual materials in the collecting bucket. The collecting bucket and the lifting plate form a cavity to prevent the materials from spilling to the outside. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1-Figure 8 As shown, an open mill for producing electric power pipes provided by the present invention comprises a base 1, a bracket 5 is fixedly installed on the base 1, two groups of rollers 2 distributed in parallel are rotatably installed in the base 1, two groups of first rotating power members 3 for driving the two groups of rollers 2 to rotate are fixedly installed on the side of the base 1, a material box 4 is fixedly installed in the base 1, the material box 4 is located between the two groups of rollers 2, and the material box 4 is a vertical through structure; A first telescopic member 6 is fixedly installed at both ends of the bracket 5, a lifting plate 7 is fixedly installed at the output end of the first telescopic member 6, a collecting bucket 8 is slidably installed on the lifting plate 7, and a moving component 27 for driving the collecting bucket 8 to move is provided on the lifting plate 7. The end of the collecting bucket 8 away from the first telescopic member 6 is an opening structure and a baffle 9 is rotatably installed at the opening structure of the collecting bucket 8. The rotating shaft connecting the baffle 9 and the collecting bucket 8 is located at the upper end of the baffle 9. The upper end of the baffle 9 is provided with an inclined structure for facilitating the entry of materials into the collecting bucket 8. The bottom surface of the collecting bucket 8 is an inclined structure and the end close to the first telescopic member 6 is the higher end. A scraper 13 is slidably installed on the inner bottom surface of the collecting bucket 8, and a power component 28 for driving the scraper 13 to move is provided on the collecting bucket 8. A push plate 22 is fixedly installed on the scraper 13. When the scraper 13 moves downward, the push plate 22 contacts the baffle 9 and pushes the baffle 9 to rotate.

[0031] In actual application of this embodiment, the first rotating power member 3 drives the roller 2 to rotate, and the rubber is refined by the two groups of rollers 2, and the powder additive to be added is evenly added to the rubber through the material box 4. During the refining, one group of the first telescopic members 6 drives the lifting plate 7 to move downward, and the lifting plate 7 stops moving after moving to the bottom of the roller 2. At this time, the collecting bucket 8 is driven by the moving component 27 to move to the bottom of the two groups of rollers 2; During rubber refining, the powder and rubber material falling downward will enter the collecting bucket 8. After the set collection time, the other set of lifting plates 7 will be moved to the same height and the collecting bucket 8 on the lifting plates 7 will be moved to the bottom of the roller 2. When the two sets of collecting buckets 8 are in contact, the two sets of baffles 9 will also be in close contact. At this time, the two sets of collecting buckets 8 will move at the same time, and the collecting bucket 8 for collecting materials will be pushed out from under the roller 2. The new collecting bucket 8 will enter under the roller 2. At this time, the falling materials will fall into the two sets of collecting buckets 8 respectively, avoiding material spillage and waste. After the new collecting bucket 8 is completely moved to the bottom of the roller 2, the collecting bucket 8 with the material collected in it is completely withdrawn from the bottom of the roller 2 and the lifting plate 7 will cover the upper part of the collecting bucket 8. At this time, the first telescopic member 6 drives the group of collecting buckets 8 to move upward until the lower end height of the collecting bucket 8 exceeds the upper end height of the material box 4 and then stops moving. At this time, the moving component 27 drives the collecting bucket 8 to move again, so that the lower end of the collecting bucket 8 moves to the top of the material box 4, and then the power component 28 drives the scraper 13 to move downward from the top of the bottom surface of the collecting bucket 8. When the scraper 13 moves downward, it pushes the material on the bottom surface of the collecting bucket 8 to move downward. After the scraper 13 moves to the lower end of the collecting bucket 8, the push plate 22 first contacts the lower end of the baffle 9 The baffle plate 9 is pushed to rotate by the push plate 22 so that the baffle plate 9 no longer closes the lower end of the collecting bucket 8. At this time, the material in the collecting bucket 8 can fall into the material box 4 through the gap between the collecting bucket 8 and the baffle plate 9. When the scraper 13 descends to the lower end of the collecting bucket 8, its lower end extends out of the collecting bucket 8, so that the material in the collecting bucket 8 can be completely pushed out of the collecting bucket 8 and fall into the material box 4, reducing the probability of material residue in the collecting bucket 8, ensuring that additives, rubber and other materials can be fully mixed, ensuring the accuracy of the material ratio, and improving the quality of the material. Subsequently, the group of collecting buckets 8 is reset and the collecting bucket 8 below is replaced by the above steps to achieve continuous material collection operations.

[0032] In an example of the present embodiment, the first rotating power component 3 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The roller 2 is driven to rotate by the first motor. The first telescopic component 6 is a first electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The lifting plate 7 is driven to move by the first electric telescopic rod.

[0033] like Figure 4 As shown, an open mill for producing electric pipes provided by the present invention, the moving component 27 includes a second rotating power member 11, the second rotating power member 11 is fixedly mounted on the outer side of the collecting bucket 8, the second rotating power member 11 drives the gear 12 to rotate, the gear 12 is engaged with the rack 10 fixedly mounted on the lifting plate 7, the lifting plate 7 is provided with a groove for installing the rack 10 and the rack 10 is distributed along the moving direction of the collecting bucket 8.

[0034] In actual application of this embodiment, the second rotating power component 11 drives the gear 12 to rotate. Since the gear 12 is meshed with the rack 10 and the lifting plate 7 is in a fixed state, when the gear 12 rotates, the collecting bucket 8 will move under the action of the rack 10. The moving direction of the collecting bucket 8 can be changed by changing the rotation direction of the second rotating power component 11.

[0035] In an example of the present invention, the second rotating power component 11 is a second motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, etc. The second motor drives the collecting bucket 8 to move.

[0036] like Figure 8 As shown, an open mill for producing electric pipes provided by the present invention, the power assembly 28 includes a screw rod 15, the screw rod 15 is rotatably installed in the collecting bucket 8, the screw rod 15 is parallel to the bottom surface of the collecting bucket 8, the projection of the screw rod 15 to the lifting plate 7 is distributed along the moving direction of the collecting bucket 8, the screw rod 15 is rotatably connected to the scraper 13, and the outer side surface of the collecting bucket 8 is fixedly installed with a third rotating power component 14 that drives the screw rod 15 to rotate.

[0037] In actual application of this embodiment, the third rotating power member 14 drives the screw rod 15 to rotate, and the screw rod 15 drives the scraper 13 to move along the bottom surface of the collecting bucket 8, so that the scraper 13 can scrape the materials on the bottom surface of the collecting bucket 8.

[0038] In an example of the present invention, the third rotating power member 14 is a third motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor. The third motor drives the screw rod 15 to rotate, thereby driving the scraper 13 to move.

[0039] like Figure 7 , Figure 8 As shown, an open mill for producing electric power pipes provided by the present invention is provided. A semicircular disengagement plate 16 is fixedly installed at the lower end of the scraper 13 , and the disengagement plates 16 are distributed along the length direction of the scraper 13 .

[0040] Specifically, a support plate 17 is fixedly installed on the scraper 13, and a plurality of groups of slide rods 18 are slidably installed on the support plate 17. The slide rods 18 penetrate the support plate 17 and a knocking plate 20 is fixedly installed on one end of the slide rods 18 close to the separation plate 16. A plurality of groups of elastic members 19 distributed around the slide rods 18 are fixedly installed on the support plate 17, and one end of the elastic member 19 away from the support plate 17 is fixedly connected to the knocking plate 20. An electromagnet 21 is fixedly installed on the support plate 17, and the electromagnet 21 is energized to adsorb the knocking plate 20, and the knocking plate 20 is made of magnetic material.

[0041] In actual application of this embodiment, when the scraper 13 scrapes the material at the bottom of the collecting bucket 8, part of the rubber will move along the scraper 13 and contact the separation plate 16. Since the separation plate 16 is a semicircular structure, the rubber will move along the separation plate 16 and finally move downward to separate, reducing the possibility of the rubber adhering to the scraper 13. When the scraper 13 moves to the lowermost end of the collecting bucket 8, the lower end of the scraper 13 extends out of the collecting bucket 8. At this time, the electromagnet 21 is powered on and off for many times. After the electromagnet 21 is powered on, it adsorbs the knocking plate 20. The knocking plate 20 moves toward the side of the support plate 17 and compresses the elastic member 19. After the electromagnet 21 is powered off, the knocking plate 20 is reset and collides with the separation plate 16 under the action of the elastic member 19. The electromagnet 21 is powered on and off multiple times to knock the separation plate 16 multiple times. Under the action of impact vibration, the scraper 13 and the material adhered to the separation plate 16 are separated, reducing the material residue on the scraper 13 and the separation plate 16, and further reducing the material residue in the collecting bucket 8, ensuring that the material participates in mixing and refining, ensuring the correct ratio of the raw materials, and improving the quality of the raw materials.

[0042] In an embodiment of the present invention, the elastic member 19 is a spring, and can also be other elastic members such as an elastic ball, and the spring is used to apply a resetting thrust to the knocking plate 20 .

[0043] like Figure 1-Figure 6 As shown, an open mill for producing electric pipes provided by the present invention is provided, wherein a plurality of groups of elastic wires 23 distributed linearly at intervals are fixedly installed on the side of the collecting bucket 8 away from the baffle 9, and the other end of the elastic wires 23 is fixedly connected to the baffle 9, and the plurality of groups of elastic wires 23 are distributed in parallel, and the elastic wires 23 are parallel to the bottom surface of the collecting bucket 8.

[0044] Specifically, a transverse plate 24 is slidably installed at one end of the collecting bucket 8 away from the baffle 9, and a plurality of push blocks 25 are fixedly installed on the transverse plate 24 and spaced apart from the elastic line 23. The cross section of the push blocks 25 is a triangular structure, and a second telescopic member 26 is fixedly installed on the outer side of the collecting bucket 8 to drive the transverse plate 24 to reciprocate.

[0045] In actual application of this embodiment, in the initial state, the elastic wire 23 is tightened to make the baffle 9 close to the collecting bucket 8. When material falls from the top of the collecting bucket 8, the powder will pass through the gap between the elastic wires 23 and fall to the bottom surface of the collecting bucket 8. Since the bottom surface of the collecting bucket 8 is an inclined structure and the powder will have a certain speed when falling, the powder will slide downward on the bottom surface of the collecting bucket 8. At this time, a layer of powder will gradually be laid on the bottom surface of the collecting bucket 8. When the rubber falls from above, the smaller rubber will pass through the gap between the elastic wires 23 and fall to the collecting bucket. At the bottom of the bucket 8, since the rubber material is small and has a small inertia, its impact force on the bottom surface of the collecting bucket 8 is small, and thus its bonding force with the collecting bucket 8 is small. In addition, since the bottom surface of the collecting bucket 8 will be gradually covered with a layer of powder material, the subsequent rubber material will first contact the powder material when it falls, and the bonding force between the powder material and the bottom surface of the collecting bucket 8 is extremely small and is sandwiched between the rubber material and the bottom surface of the collecting bucket 8, further reducing the ability of the rubber material to bond with the bottom surface of the collecting bucket 8, thereby reducing the subsequent force between the scraper 13 and the material when scraping the material, and reducing the possibility of the scraper 13 bonding with the material; When the rubber material with a larger volume falls, it will contact with the multiple groups of elastic lines 23. Since the rubber material with a larger volume has a larger weight and a larger inertia, the speed of the rubber material when contacting with the elastic lines 23 is faster and the impact is greater. Therefore, the multiple groups of elastic lines 23 can divide the rubber material with a larger volume into multiple groups of smaller rubber materials. The separated rubber materials continue to fall downward to the bottom of the collecting bucket 8. When dividing the rubber materials, the elastic lines 23 will reduce the speed of the rubber materials falling, further reduce the impact of the rubber materials on the bottom surface of the collecting bucket 8 when falling, and further reduce the ability of the rubber materials to adhere to the collecting bucket 8, so as to facilitate the subsequent cleaning of the rubber materials. After the collection of materials is completed, the collecting bucket 8 is pushed out from under the roller 2, and the lifting plate 7 will cover the upper part of the collecting bucket 8, so that the collecting bucket 8 forms a cavity, and the cross plate 24 is driven to move back and forth by the second telescopic member 26, and the cross plate 24 drives the pushing block 25 to move back and forth. When the cross plate 24 moves, it contacts the elastic line 23 on the front side of its moving direction and pushes the elastic line 23 to further stretch. Since the surface of the pushing block 25 in contact with the elastic line 23 is an inclined surface, the elastic line 23 will be separated from the pushing block 25 after being stretched to a set length. After the elastic line 23 is separated from the pushing block 25, it will vibrate. When the elastic line 23 vibrates, adjacent elastic lines 23 can collide with each other. Under the action of the vibration, the materials adhered to the elastic lines 23 are separated and fall onto the bottom surface of the collecting bucket 8, further reducing the residual materials in the collecting bucket 8. The collecting bucket 8 and the lifting plate 7 form a cavity to prevent the materials from spilling to the outside.

[0046] In an example of the present invention, the second telescopic member 26 is a second electric telescopic rod, and of course, it can also be other components that can actively change the length, such as a hydraulic cylinder, and the second electric telescopic rod drives the cross plate 24 to move back and forth.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
