Description

Technical Field

[0001] The utility model relates to the technical field of roll installation of an open mill, and particularly relates to a bracket assembly for roll installation of an open mill. Background Art

[0002] The open mill is a rubber factory used to prepare plasticized rubber, mixed rubber, or to conduct hot refining and profiling. It is a rubber mixing machine with exposed rollers. Its main working components are two inwardly rotating hollow rollers or drilled rollers.

[0003] When replacing and installing the rollers, since the roller installation has a certain height, an installation bracket is usually required to assist in the installation. However, when the installation bracket lifts and moves the rollers, the stability of the rollers is poor and there is a risk of falling off during lifting.

[0004] Therefore, a bracket assembly for roll installation of an open mill is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bracket assembly for roll installation of an open mill to solve the above problems, and to improve the problem that when the installation bracket lifts and moves the rollers, the stability of the rollers is poor and there is a risk of falling off during lifting.

[0006] The utility model realizes the above purpose through the following technical solutions. A bracket assembly for roll installation of an open mill includes: a base, a mounting frame fixedly installed on the top of the base, a limit installation mechanism for facilitating the lifting and installation of the rollers and limiting the rollers during installation. The limit installation mechanism is arranged inside the mounting frame. Among them, the limit installation mechanism includes a limit installation component arranged inside the mounting frame for lifting and moving the rollers and limiting them. One side of the limit installation component is provided with a stable component for protecting the rollers when they enter the limit installation component. The rollers can be lifted and moved through the limit installation component, which is convenient for the installation of the rollers. And during the movement of the rollers, the rollers can also be limited through the limit installation component, making the rollers more stable during the movement. The stable component can slow down the impact of the weight of the rollers when the rollers enter the inside of the limit installation component, thereby reducing the damage caused by the rollers to the limit installation component.

[0007] The limiting and mounting assembly includes guide plates slidably mounted on both sides inside the mounting frame. Guide grooves are formed on one side of each of the two guide plates. A moving plate is arranged on one side of the two guide plates. The moving plate and the two guide plates are connected to each other through a stabilizing assembly. A first motor is fixedly mounted on the top of the base. A first screw rod is fixedly connected to one side of the first motor. The first screw rod passes through the moving plate and is threadedly connected to the moving plate. The roller is slidably arranged between the two guide plates through the two guide grooves 202. The first motor can be driven to rotate the first screw rod, so that the first screw rod moves threadedly with the moving plate, driving the moving plate to drive the two guide plates to move up and down, so that the two guide plates can drive the roller to move synchronously, so that the roller reaches the specified height and then moves out through the guide groove for installation;

[0008] The stabilizing assembly includes fixing blocks fixedly mounted on one side of the two guide plates. Two sealing tubes are fixedly connected to the surface of the moving plate. One end of each of the two sealing tubes extends below the moving plate. The two sealing tubes are respectively located at the bottoms of the two fixing blocks. A piston rod is fixedly connected to the bottom of each of the two fixing blocks. The two piston rods are respectively slidably connected to the two sealing tubes. Hydraulic oil is arranged inside the sealing tubes. When the roller enters the guide groove, the weight is transferred to the guide plates, so that the guide plates synchronously push the piston rods down. The piston rods can move inside the sealing tubes, so that the hydraulic oil pressure inside the sealing tubes below the piston rods increases, which can provide a certain component for the movement of the piston rods, thereby slowing down the impact on the moving plate when the roller moves onto the guide plates.

[0009] Preferably, the limiting and mounting assembly further includes a second motor fixedly mounted on the surface of the moving plate. A second screw rod is fixedly mounted on the surface of the moving plate. The second screw rod is located on one side of the second motor. Conical gears are fixedly connected to the output end of the second motor and the surface of the second screw rod. The two conical gears are meshed with each other. A first clamping plate is slidably sleeved on the surface of the first screw rod. One end of the second screw rod passes through the first clamping plate and is threadedly connected to the first clamping plate. Before the roller moves, the second motor can be driven to rotate the second screw rod, so that the second screw rod drives the first clamping plate to move down to tightly limit the roller, which can make the roller more stable during movement and avoid the roller slipping when the roller is moved up and down.

[0010] Preferably, a support rod is fixedly connected to the bottom of the moving plate. A same second clamping plate is slidably connected to the surfaces of the support rod and the first screw rod. The surface of the support rod is sleeved with a first spring through which the other end of the first spring is fixedly connected to the second clamping plate. When the roller enters the inside of the guiding groove, the second clamping plate is synchronously squeezed, so that the second clamping plate moves on the surface of the support rod, and at the same time, the first spring is deformed. The second clamping plate is squeezed by the first spring to preliminarily press against the roller, and when the first clamping plate moves downward, they can be used in cooperation to clamp and limit both sides of the roller at the same time, improving the limiting effect on the roller.

[0011] Preferably, a plurality of rubber blocks are fixedly connected to the adjacent sides of the first clamping plate and the second clamping plate. All the plurality of rubber blocks are semicircular in shape. The plurality of rubber blocks connected to the surfaces of the first clamping plate and the second clamping plate can reduce the wear caused when contacting the surface of the roller, and can also increase the contact friction force, making the first clamping plate and the second clamping plate more stable when pressing against and limiting the roller.

[0012] Preferably, a sealing tank is arranged on one side of the sealing pipe. The sealing tank is fixedly connected to one side of the moving plate. The sealing pipe and the sealing tank are interconnected through a conveying pipe. One end of the piston rod is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the inner wall of the sealing pipe. When the piston rod moves downward, hydraulic oil can be moved through the conveying pipe into the inside of the sealing tank to synchronously squeeze the second spring. When the hydraulic oil passes through the relatively narrow conveying pipe, resistance is generated, and when the hydraulic oil enters the inside of the sealing tank, the pressure of the hydraulic oil inside the sealing tank will also be increased synchronously to further increase the resistance. Thus, the moving speed and frequency of the piston rod can be slowed down to further reduce the damage to the moving plate caused by the impact, reducing the impact force and damage to the roller when the roller moves onto the limiting installation assembly.

[0013] Preferably, a plurality of universal wheels are fixedly installed at the bottom of the base. The plurality of universal wheels are evenly distributed at the four corners of the base. The base can be conveniently moved through the universal wheels at the bottom to quickly transfer the roller.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. During use, the roller can be lifted and moved through the limiting installation assembly in the limiting installation mechanism, facilitating the installation of the roller. And during the movement of the roller, the roller can also be limited by the limiting installation assembly, making the roller more stable during the movement. The stabilizing assembly can slow down the impact force generated when the roller enters the limiting installation assembly when the roller enters the inside of the limiting installation assembly, thereby reducing the damage caused by the roller to the limiting installation assembly and extending the service life of the limiting installation assembly;

[0016] 2. When the roller enters the guiding groove, the weight is transferred to the guiding plate, causing the guiding plate to synchronously push the piston rod downward. The piston rod can move inside the sealing tube, enabling the hydraulic oil inside the sealing tube below the piston rod to move through the delivery pipe into the inside of the sealing tank, simultaneously compressing the second spring. As the hydraulic oil passes through the relatively narrow delivery pipe, resistance is generated. Moreover, when the hydraulic oil enters the inside of the sealing tank, the pressure of the hydraulic oil inside the sealing tank will also increase synchronously, further enhancing the resistance. Thus, the moving speed and frequency of the piston rod can be slowed down, further reducing the damage to the moving plate caused by the impact, and reducing the impact force and damage when the roller moves onto the limit installation component.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4As shown in the figure, a bracket assembly for the installation of roll cylinders of an open mill includes: a base 1, a mounting frame 101 fixedly installed on the top of the base 1, and a limit installation mechanism for facilitating the lifting and installation of the roll cylinder and limiting the roll cylinder during installation. The limit installation mechanism is arranged inside the mounting frame 101. Among them, the limit installation mechanism includes a limit installation component 2 arranged inside the mounting frame 101 for lifting and moving the roll cylinder and limiting it. A stabilizing component 3 for protecting the roll cylinder when it enters the limit installation component 2 is arranged on one side of the limit installation component 2. The roll cylinder can be lifted and moved through the limit installation component 2, which is convenient for the installation of the roll cylinder. And during the movement of the roll cylinder, the roll cylinder can also be limited by the limit installation component 2, making the roll cylinder more stable during the movement. The stabilizing component 3 can slow down the impact of the weight of the roll cylinder when the roll cylinder enters the inside of the limit installation component 2, thereby reducing the damage caused by the roll cylinder to the limit installation component 2.

[0024] As Figures 2-4 shown in the figure, the limit installation component 2 includes guide plates 201 slidably installed on both sides inside the mounting frame 101. Guide grooves 202 are formed on one side of each of the two guide plates 201. A moving plate 203 is arranged on one side of the two guide plates 201. The moving plate 203 is connected to the two guide plates 201 through a stabilizing component 3. A first motor 204 is fixedly installed on the top of the base 1. A first screw rod 205 is fixedly connected to one side of the first motor 204. The first screw rod 205 passes through the moving plate 203 and is threadedly connected to the moving plate 203. The first screw rod 205 can be driven to rotate by the first motor 204, enabling the first screw rod 205 to move in a threaded manner with the moving plate 203, driving the moving plate 203 to drive the two guide plates 201 to move up and down, so that the two guide plates 201 can drive the roll cylinder to move synchronously, making the roll cylinder reach the specified height and then be removed through the guide grooves 202 for installation;

[0025] The limit installation component 2 further includes a second motor 206 fixedly installed on the surface of the moving plate 203. A second screw rod 207 is fixedly installed on the surface of the moving plate 203. The second screw rod 207 is located on one side of the second motor 206. Conical gears 210 are fixedly connected to the output end of the second motor 206 and the surface of the second screw rod 207 respectively. The two conical gears 210 are meshed with each other. A first clamping plate 208 is slidably sleeved on the surface of the first screw rod 205. One end of the second screw rod 207 penetrates through the first clamping plate 208 and is threadedly connected to the first clamping plate 208. Before the roller moves, the second motor 206 can be driven to rotate the second screw rod 207, so that the second screw rod 207 drives the first clamping plate 208 to move downward to tightly limit the roller, making the roller more stable during movement and avoiding the roller from slipping when the roller is lifted and moved. A support rod 211 is fixedly connected to the bottom of the moving plate 203. A second clamping plate 209 is slidably connected to the surfaces of the support rod 211 and the first screw rod 205. A first spring 212 is sleeved through the surface of the support rod 211. The other end of the first spring 212 is fixedly connected to the second clamping plate 209. When the roller enters the inside of the guiding groove 202, the second clamping plate 209 is synchronously squeezed, so that the second clamping plate 209 moves on the surface of the support rod 211, and at the same time, the first spring 212 is deformed. The second clamping plate 209 is preliminarily tightened against the roller by the first spring 212. When the first clamping plate 208 moves downward, they can be used in cooperation to clamp and limit both sides of the roller at the same time, improving the limiting effect on the roller. A plurality of rubber blocks 213 are fixedly connected to the adjacent sides of the first clamping plate 208 and the second clamping plate 209. The plurality of rubber blocks 213 are all set in a semicircular shape. The plurality of rubber blocks 213 connected to the surfaces of the first clamping plate 208 and the second clamping plate 209 can reduce the wear caused by contact with the surface of the roller, and can also increase the contact friction force, making the first clamping plate 208 and the second clamping plate 209 more stable when tightly limiting the roller.

[0026] Such as Figures 2-4As shown in the figure, the stabilizing component 3 includes a fixed block 301 fixedly installed on one side of two guide plates 201. Two sealing tubes 302 are fixedly connected to the surface of the moving plate 203. One end of each of the two sealing tubes 302 extends below the moving plate 203, and the two sealing tubes 302 are respectively located at the bottom of the two fixed blocks 301. A piston rod 303 is fixedly connected to the bottom of each of the two fixed blocks 301, and the two piston rods 303 are respectively slidably connected to the two sealing tubes 302. Hydraulic oil is provided inside the sealing tubes 302. When the roller enters the guide groove 202, the weight is transferred to the guide plate 201, causing the guide plate 201 to synchronously push the piston rod 303 downward. The piston rod 303 can move inside the sealing tube 302, increasing the pressure of the hydraulic oil inside the sealing tube 302 below the piston rod 303, providing a certain component for the movement of the piston rod 303, thereby reducing the impact on the moving plate 203 when the roller moves onto the guide plate 201. A sealing tank 306 is provided on one side of the sealing tube 302. The sealing tank 306 is fixedly connected to one side of the moving plate 203. The sealing tube 302 and the sealing tank 306 are interconnected through a delivery pipe 305. One end of the piston rod 303 is fixedly connected to a second spring 304, and the other end of the second spring 304 is fixedly connected to the inner wall of the sealing tube 302. Hydraulic oil is provided inside the sealing tank 306. The diameter of the delivery pipe 305 is several times smaller than that of the sealing tube 302, and the specific size can be adjusted according to the actual use situation. When the piston rod 303 moves downward, the hydraulic oil can be allowed to move into the sealing tank 306 through the delivery pipe 305, simultaneously compressing the second spring 304. When the hydraulic oil passes through the narrower delivery pipe 305, resistance is generated, and when the hydraulic oil enters the sealing tank 306, the pressure of the hydraulic oil inside the sealing tank 306 is also increased synchronously, further enhancing the resistance. Thus, the moving speed and frequency of the piston rod 303 can be reduced, further reducing the damage to the moving plate 203 caused by the impact, and reducing the impact force and damage when the roller moves onto the limit installation component 2. A plurality of universal wheels 102 are fixedly installed at the bottom of the base 1, and the plurality of universal wheels 102 are evenly distributed at the four corners of the base 1. The base 1 can be conveniently moved through the universal wheels 102 at the bottom to quickly transfer the roller.

[0027] When the utility model is in use, the first motor 204 can be used to drive the first screw rod 205 to rotate, so that the first screw rod 205 moves in a threaded manner with the moving plate 203, and the moving plate 203 is driven to drive the two guide plates 201 to move up and down, so that the two guide plates 201 can drive the roller to move synchronously, so that the roller reaches the specified height and then is moved out through the guide groove 202 for installation. Before the roller moves, the second motor 206 can be used to drive the second screw rod 207 to rotate, so that the second screw rod 207 drives the first clamping plate 208 to move downwards to tightly limit the roller, which can make the roller more stable when moving, and avoid the roller slipping when the roller is lifted and lowered. When the roller enters the inside of the guide groove 202, the second clamping plate 209 is synchronously extruded, so that the second clamping plate 209 moves on the surface of the support rod 211, and at the same time, the first spring 212 is deformed. The first spring 212 is used to extrude the second clamping plate 209 to preliminarily tightly limit the roller, and when the first clamping plate 208 moves downwards, it can be used in cooperation to simultaneously clamp and limit both sides of the roller, improving the limiting effect on the roller. A plurality of rubber blocks 213 connected to the surfaces of the first clamping plate 208 and the second clamping plate 209 can be used to reduce the wear caused by contact with the surface of the roller, and can also increase the contact friction force, making the first clamping plate 208 and the second clamping plate 209 more stable when tightly limiting the roller. When the roller enters the guide groove 202, the weight is transferred to the guide plate 201, so that the guide plate 201 synchronously pushes the piston rod 303 to move downwards. The piston rod 303 can move inside the sealing tube 302, so that the hydraulic oil can move through the delivery pipe 305 into the inside of the sealing tank 306, synchronously squeezing the second spring 304. When the hydraulic oil passes through the relatively narrow delivery pipe 305, resistance is generated, and when the hydraulic oil enters the inside of the sealing tank 306, the pressure of the hydraulic oil inside the sealing tank 306 is also increased synchronously to further increase the resistance. Thus, the moving speed and frequency of the piston rod 303 can be slowed down, and the impact on the moving plate 203 can be further reduced, so as to reduce the impact force and damage when the roller moves to the limit installation component 2.

[0028] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
