Description

Technical Field

[0001] The invention relates to the technical field of rubber machinery, in particular to a numerically controlled rubber roller winding and covering device. Background Art

[0002] The rubber roller wrapping machine is a commonly used machine for rubber roller wrapping. It heats the rubber barrel, controls the temperature of the screw and the die head, and at the same time, the cold feed extruder extrude a certain shape of rubber strip from the straight rubber outlet to form a continuous belt of soft rubber. Then, it passes through the conveying and pressing device and is hot-attached to the core shaft of the rubber roller by spiral winding. The tape is pressed against the original workpiece through the pneumatic rod, and the tape is wound onto the workpiece by rolling the workpiece and moving the worktable back and forth. Due to its good density, high degree of automation and production efficiency, and saving of raw materials, the rubber roller wrapping machine has been widely used in the rubber roller production industry.

[0003] During the rubber roller wrapping process, parameters such as temperature, workpiece rotation speed and worktable movement speed can be precisely controlled through the instrument panel data. However, the thickness of the rubber layer wrapped on the rubber roller core cannot be automatically detected, and the operator needs to use a vernier caliper to manually measure it on the rotating workpiece.

[0004] There are the following disadvantages in measuring with a vernier caliper: 1. Since the workpiece rotates during the rubber coating process, it is difficult to measure accurately; 2. When measuring a rotating workpiece with a vernier caliper, the vernier caliper is easily driven by the rotating workpiece to rotate synchronously when the vernier caliper contacts the workpiece, which can easily cause injury to the operator; 3. Controlling the feeding extruder through a set program to drive the rubber pressing roller to move at the required speed will increase the complexity of the extruder system and require more sensors, controllers and actuators, increasing the difficulty of system maintenance and debugging. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a numerically controlled rubber roller winding and covering device to solve the problems existing in the above-mentioned background technology.

[0010] Preferably, the driving device comprises a driving wheel, the driving wheel is arranged at the bottom of the column, a second motor for driving the driving wheel is arranged on the side of the column, and the driving wheel can abut against the outer surface of the rubber layer.

[0011] Preferably, the rubber layer guiding device includes an elastic telescopic rod, a guide roller is provided at one end of the elastic telescopic rod away from the rubber roller, a V-shaped clamp is provided at one end of the elastic telescopic rod close to the rubber roller, and rubber pressing rollers that can abut against the outer surface of the rubber layer are provided at both ends of the V-shaped clamp, and the rubber pressing rollers are kept parallel to the driving wheel.

[0012] Preferably, the elastic telescopic rod comprises a shell, a pressure rod is slidably arranged inside the shell, one end of the pressure rod close to the rubber roller is connected to the V-shaped clip, and the other end of the pressure rod is connected to the inside of the shell through a spring.

[0013] Preferably, a sleeve is provided on the side of the vertical plate, a pull rod is slidably provided in the sleeve, the free end of the pull rod has a mounting hole, a knife handle is slidably provided in the mounting hole, and a cutting knife is provided at one end of the knife handle close to the rubber roller.

[0014] The beneficial effects of the embodiments of the present invention are:

[0015] 1. In this device, the operator can adjust the distance between the driving device at the bottom and the rubber roller through the liftable distance measuring device, and reserve the thickness of the rubber layer that needs to be wound on the rubber roller in advance. When the thickness of the rubber layer wound on the surface of the rubber roller driven by the rotation of the rubber roller reaches the preset thickness, the outer surface of the rubber layer can abut against the bottom of the driving device. When the outer surface of the rubber layer abuts against the driving device, the rotation of the driving device can drive the sliding device to slowly move in the direction where the rubber roller is not yet wound with the rubber layer. When the sliding device moves, the rubber layer guide device can be driven to move synchronously through the connecting frame. Since the sliding device drives the driving device to move in the direction where the rubber roller is not yet wound with the rubber layer, the driving device cannot continue to move when the thickness of the rubber layer wound on the rubber roller has not reached the requirement. The sliding device is driven to move, so that the interlayer guide device drives the rubber layer to cooperate with the rotating rubber roller, so that the rubber layer is continuously wound on the outer surface of the rubber roller. Through the cooperation of the sliding device and the driving device, the rubber layer is continuously wound on the surface of the rubber roller. In conjunction with the distance measuring device, the thickness of the rubber layer wound on the rubber roller can be controlled. During the whole process, there is no need for the operator to use a vernier caliper to measure the thickness of the rubber layer wrapped on the rubber roller, thereby reducing the labor intensity of the operator and the risk of the operator using a vernier caliper to measure the thickness of the rubber layer. At the same time, the thickness of the rubber layer can be accurately controlled, and the complexity of the electronic control system of the device is reduced, without the need for a large number of sensors, controllers and actuators, thereby reducing the difficulty of system maintenance and debugging.

[0016] 2. The guide rod of this device is divided into two, and the two guide rods are horizontally arranged side by side at the upper end between the two vertical plates, ensuring that the sliding seat installed on the guide rod can be directly above the rubber roller. When the sliding seat moves, it can effectively cooperate with the driving device, thereby driving the rubber layer guiding device to move along the length direction of the rubber roller, so that the rubber layer guiding device.

[0017] 3. In this device, the operator can drive the threaded rod to move up and down in the threaded hole at the top of the limit shell by rotating the handle. Since the bottom of the threaded rod is located in the limit shell and a mounting plate is rotatably installed, the bottom of the mounting plate is connected to a column, and the bottom end of the column is arranged toward the direction of the rubber roller through the through hole on the mounting seat. A scale is provided on the side of the column. By rotating the rotating handle, the threaded rod can drive the column to rise and fall synchronously in the limit shell. The distance between the bottom end of the column and the rubber roller can be clearly known through the scale on the side of the column. Since a driving device is provided at the bottom end of the column, the distance between the driving device and the rubber roller can be accurately controlled, and the thickness of the rubber layer wrapped around the rubber roller can be reserved in advance. There is no need for the operator to measure the thickness of the rubber layer with a vernier caliper in the later stage, thereby reducing the labor intensity of the operator.

[0018] 4. The bottom end of the driving wheel of the device can be in contact with the rubber layer wrapped on the surface of the rubber roller, and the column can drive the bottom driving wheel to rise and fall when it is raised or lowered, so that the operator can control the distance between the bottom end of the driving wheel and the rubber roller and reserve the thickness of the rubber layer in advance. Driven by the second motor, the driving wheel can rotate slowly, so that when the thickness of the rubber layer reaches the reserved thickness, the sliding seat can be driven to move on the guide rod through the rotation of the driving wheel, thereby controlling the movement of the rubber layer guide device along the length direction of the rubber roller to ensure that the entire surface of the rubber roller is covered with glue.

[0019] 5. This device can be set toward the position where the rubber roller and the rubber pressure roller abut against each other through the guidance of the guide roller. Through the rotation of the rubber roller, it can ensure that the rubber layer is continuously wound around the surface of the rubber roller. The rubber pressure roller can effectively ensure the uniformity and consistency of the rubber layer winding on the rubber roller. Since the rubber pressure roller can abut against the rubber layer wound on the surface of the rubber roller, when the thickness of the rubber layer wound on the rubber roller gradually increases, the elastic telescopic rod can be compressed when the rubber layer of the V-shaped clamp gradually thickens, ensuring that the rubber roller always abuts against the surface of the rubber layer. The two rubber pressure rollers at the ends of the V-shaped clamp can abut against the rubber layer, ensuring the uniformity and consistency of the rubber layer winding regardless of whether the rubber roller rotates forward or reverse.

[0020] 6. When the thickness of the rubber layer of the device gradually increases, due to the action of the rubber pressing roller, the V-shaped clamp forces the driving wheel arranged at the bottom of the column to gradually shrink into the shell body. The arranged spring can ensure that the rubber pressing roller of the V-shaped clamp arranged at the bottom end of the column of the driving wheel is always in contact with the rubber layer on the rubber roller.

[0021] 7. In this device, the operator pulls the pulling rod out of the sleeve to ensure that the cutting knife in the mounting hole at the end of the pulling rod remains parallel to the excess rubber layer at the end of the rubber roller. Since the handle of the cutting knife is arranged in the mounting hole, when the operator pushes the handle in the mounting hole, the blade of the cutting knife can cut the excess rubber layer at the end of the rubber roller. The force generated by the cutting knife cutting off the excess rubber layer is completely borne by the sleeve, the pulling rod 27 and the handle, thereby reducing the labor intensity of the operator and ensuring the safety of the operator when cutting off the excess rubber layer at both ends of the rubber roller.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] A numerically controlled rubber roller winding and covering device, such as Figure 1-Figure 5 As shown, it includes a base 3, both ends of the top of the base 3 are provided with vertical plates 4, and a first motor 5 and an electric push rod 6 are respectively provided on the two vertical plates 4, the power output end of the first motor 5 and the power output end of the electric push rod 6 are arranged opposite to each other, a conical mounting cover 7 is provided on the power output end of the first motor 5, and a conical mounting cover 7 is rotatably provided on the power output end of the electric push rod 6, and a rubber roller 8 is clamped between the two mounting covers 7, a feeding extruder 1 is provided on one side of the base 3, and an extrusion port 2 is provided on the side of the feeding extruder 1 close to the base 3, a sliding device is provided at the upper end between the two vertical plates 4, a distance measuring device that can be raised and lowered is installed on the sliding device, a driving device is provided at the bottom end of the distance measuring device, a rubber layer 9 guide device is installed on one side of the sliding device through an L-shaped connecting frame 10, a rubber layer 9 is wound around the rubber roller 8, and the driving device can abut against the outer surface of the rubber layer 9.

[0031] When the operator places the rubber roller 8 between the two mounting covers 7, the operation of the electric push rod 6 can ensure that the rubber roller 8 is stably clamped between the two mounting covers 7. Since the mounting cover 7 at the power output end of the electric push rod 6 is rotatably connected, when the first motor 5 is working, the rubber roller 8 between the two mounting covers 7 can be driven to rotate. When the feeding extruder 1 is working, the rubber layer 9 can be extruded through the extrusion port 2. The operator can guide the rubber layer 9 to the rubber roller 8 through the rubber layer 9 guide device. Through the operation of the first motor 5, the rubber layer 9 can be driven to be wound on On the rubber roller 8, a sliding device arranged at the upper end between the two vertical plates 4 is located directly above the rubber roller 8. The operator can adjust the distance between the driving device at the bottom and the rubber roller 8 through the liftable distance measuring device, and reserve in advance the thickness of the rubber layer 9 that needs to be wound on the rubber roller 8. When the rubber roller 8 rotates to drive the rubber layer 9 to be wound on its surface, the outer surface of the rubber layer 9 can abut against the bottom of the driving device. When the outer surface of the rubber layer 9 abuts against the driving device, the rotation of the driving device can drive the sliding device to the rubber roller 8 where there is no rubber wound. The rubber layer 9 slowly moves in the direction of the rubber roller 8. When the sliding device moves, the connecting frame 10 can drive the rubber layer 9 guiding device to move synchronously. Since the sliding device drives the driving device to move in the direction where the rubber layer 9 is not yet wound on the rubber roller 8, when the thickness of the rubber layer 9 wound on the rubber roller 8 has not reached the requirement, the driving device cannot continue to drive the sliding device to move, so that the sandwich guiding device drives the rubber layer 9 to cooperate with the rotating rubber roller 8 to realize that the rubber layer 9 is continuously wound on the outer surface of the rubber roller 8. Through the mutual cooperation of the sliding device and the driving device, the rubber layer 9 is continuously wound on the surface of the rubber roller 8. With the help of the distance measuring device, the thickness of the rubber layer 9 wound on the rubber roller 8 can be controlled. The whole process does not require the operator to use a vernier caliper to measure the thickness of the rubber layer 9 wound on the rubber roller 8, thereby reducing the labor intensity of the operator and reducing the danger of the operator using a vernier caliper to measure the thickness of the rubber layer 9. At the same time, the thickness of the rubber layer 9 can be accurately controlled, and the complexity of the electronic control system of the device is reduced, without more sensors, controllers and actuators, thereby reducing the difficulty of maintenance and debugging of the system.

[0032] The sliding device comprises a guide rod 11 , which is arranged at the upper end between the two vertical plates 4 , and a sliding seat 12 is slidably arranged on the guide rod 11 .

[0033] The guide rod 11 is divided into two, and the two guide rods 11 are horizontally arranged side by side at the upper end between the two vertical plates 4, ensuring that the sliding seat 12 installed on the guide rod 11 can be directly above the rubber roller 8. When the sliding seat 12 moves, it can effectively cooperate with the driving device, thereby driving the rubber layer 9 guide device to move along the length direction of the rubber roller 8, so that the rubber layer 9 on the rubber layer 9 guide device can cooperate with the rotating rubber roller 8, and the rubber layer 9 is wound around the surface of the entire rubber roller 8.

[0034] A through hole is provided in the middle of the sliding seat 12, and the distance measuring device includes a limit shell 13, which is arranged at the bottom of the sliding seat 12, and a threaded hole is provided on the top of the limit shell 13, in which a threaded rod 15 is installed, and a handle 16 is provided on the top of the threaded rod 15, and a mounting plate 14 is rotatably provided on the top of the threaded rod 15, and a column 18 is provided on the top of the mounting plate 14, and the top of the column 18 passes through the through hole on the mounting seat, and a scale 17 is provided on the side of the column 18.

[0035] When it is necessary to preset the thickness of the rubber layer 9 wound on the rubber roller 8 in advance, the operator can drive the threaded rod 15 to move up and down in the threaded hole at the top of the limiting shell 13 by rotating the handle 16. Since the bottom of the threaded rod 15 is located in the limiting shell 13 and a mounting plate 14 is rotatably installed, a column 18 is connected to the bottom of the mounting plate 14. The bottom end of the column 18 passes through the through hole on the mounting seat and is arranged toward the rubber roller 8. A scale 17 is provided on the side of the column 18. By rotating the rotating handle 16, the threaded rod 15 can drive the column 18 to rise and fall synchronously in the limiting shell 13. The distance between the bottom end of the column 18 and the rubber roller 8 can be clearly known through the scale 17 on the side of the column 18. Since a driving device is provided at the bottom end of the column 18, the distance between the driving device and the rubber roller 8 can be accurately controlled, and the thickness of the rubber layer 9 wound on the rubber roller 8 can be reserved in advance. There is no need for the operator to measure the thickness of the rubber layer 9 with a vernier caliper in the later stage, thereby reducing the labor intensity of the operator.

[0036] The driving device includes a driving wheel 19 , which is disposed at the bottom of the column 18 . A second motor 20 for driving the driving wheel 19 is disposed on the side of the column 18 . The driving wheel 19 can abut against the outer surface of the adhesive layer 9 .

[0037] The bottom end of the driving wheel 19 can be in contact with the rubber layer 9 wound on the surface of the rubber roller 8, and the column 18 can drive the bottom driving wheel 19 to rise and fall when it is raised or lowered, so that the operator can control the distance between the bottom end of the driving wheel 19 and the rubber roller 8, and reserve the thickness of the rubber layer 9 in advance. Driven by the second motor 20, the driving wheel 19 can rotate slowly, so that when the thickness of the rubber layer 9 reaches the reserved thickness, the driving wheel 19 can rotate to drive the sliding seat 12 to move on the guide rod 11, thereby controlling the rubber layer 9 guide device to move along the length direction of the rubber roller 8, ensuring that the entire surface of the rubber roller 8 is covered with glue.

[0038] The guiding device of the rubber layer 9 includes an elastic telescopic rod 21, and a guide roller 25 is provided at the end of the elastic telescopic rod 21 away from the rubber roller 8, and a V-shaped clamp 22 is provided at the end of the elastic telescopic rod 21 close to the rubber roller 8. The two ends of the V-shaped clamp 22 are provided with rubber pressing rollers 23 that can abut against the outer surface of the rubber layer 9, and the rubber pressing rollers 23 remain parallel to the driving wheel 19.

[0039] When the rubber layer 9 is extruded from the feeding extruder 1, it can be set toward the position where the rubber roller 8 and the rubber pressing roller 23 abut against each other through the guidance of the guide roller 25. Through the rotation of the rubber roller 8, it can be ensured that the rubber layer 9 is continuously wound around the surface of the rubber roller 8. The set rubber pressing roller 23 can effectively ensure the uniformity and consistency of the rubber layer 9 wound on the rubber roller 8. Since the rubber pressing roller 23 can abut against the rubber layer 9 wound on the surface of the rubber roller 8, when the thickness of the rubber layer 9 wound on the rubber roller 8 gradually increases, the set elastic telescopic rod 21 can ensure that the V-shaped clamp 22 can be compressed when the rubber layer 9 gradually thickens, ensuring that the rubber roller 8 always abuts against the surface of the rubber layer 9, and the two rubber pressing rollers 23 at the ends of the V-shaped clamp 22 can abut against the rubber layer 9. Regardless of whether the rubber roller 8 rotates forward or reverse, the uniformity and consistency of the winding of the rubber layer 9 are ensured.

[0040] The elastic telescopic rod 21 includes a shell, and a pressure rod is slidably arranged inside the shell. One end of the pressure rod close to the rubber roller 8 is connected to the V-shaped clip 22, and the other end of the pressure rod is connected to the inside of the shell through a spring 24.

[0041] The shell is arranged at one end of the L-shaped connecting frame 10 away from the sliding seat 12. When the thickness of the rubber layer 9 is gradually increased, due to the action of the rubber pressing roller 23, the V-shaped clamp 22 forces the driving wheel 19 arranged at the bottom of the column 18 to gradually shrink into the shell. The spring 24 can ensure that the rubber pressing roller 23 on the V-shaped clamp 22 at the bottom end of the column 18 of the driving wheel 19 is always in contact with the rubber layer 9 on the rubber roller 8.

[0042] Embodiment 2

[0043] On the basis of the first embodiment, a sleeve 26 is provided on the side of the vertical plate 4, a pull rod 27 is slidably provided in the sleeve 26, the free end of the pull rod 27 has a mounting hole, a knife handle 28 is slidably provided in the mounting hole, and a cutting knife 29 is provided at one end of the knife handle 28 close to the rubber roller 8.

[0044] When the rubber layer 9 on the rubber roller 8 is wound to a required thickness, the winding work of the rubber layer 9 is stopped. Since the extruded rubber layer 9 will form redundant parts at both ends of the rubber roller 8, these redundant rubber layers 9 need to be cut off to prevent bubbles or uneven rubber layers 9 from being generated during the subsequent vulcanization process. The existing work of cutting off the redundant rubber layer 9 is that the operator holds a cutting knife 29 to cut off the rubber layer 9 at both ends of the rubber roller 8. Since the cutting work of the redundant rubber layer 9 is performed when the rubber roller 8 is rotating, the force generated by the cutting knife 29 when cutting off the redundant rubber layer 9 is completely applied to the operator's hand, which not only increases the labor intensity of the operator, but also affects the safety of the operator.

[0045] By setting a sleeve 26 on the side of the vertical plate 4 and slidingly setting a pulling rod 27 in the sleeve 26, when it is necessary to cut off the excess rubber layer 9 at both ends of the rubber roller 8, the operator pulls the pulling rod 27 out of the sleeve 26 to ensure that the cutting knife 29 in the mounting hole at the end of the pulling rod 27 remains parallel to the excess rubber layer 9 at the end of the rubber roller 8. Since the handle 28 of the cutting knife 29 is set in the mounting hole, when the operator pushes the handle 28 in the mounting hole, the blade of the cutting knife 29 can cut the excess rubber layer 9 at the end of the rubber roller 8. The force generated by the cutting knife 29 cutting off the excess rubber layer 9 is completely borne by the sleeve 26, the pulling rod 27 and the handle 16, thereby reducing the labor intensity of the operator and ensuring the safety of the operator when cutting off the excess rubber layer 9 at both ends of the rubber roller 8.

[0046] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
