Description

Servo coiled material embossing device and coiled material production line

Technical Field

The utility model relates to the field of coiled material production, in particular to a servo coiled material embossing device and a coiled material production line.

Background

The waterproof roll is mainly used for roofs of industrial and civil buildings, underground waterproof engineering, public works such as tunnels, railways and bridges, and has the function of resisting external water from permeating into buildings or corroding building structures. The waterproof roll may be classified into an asphalt waterproof material, a high polymer modified waterproof roll and a synthetic polymer waterproof roll according to its main waterproof constituent material.

The embossing refers to a process of rolling and extruding patterns on the surface of the waterproof roll by using a driving roller with the surface provided with the patterns, and is one of the production processes of the waterproof roll. The depth and uniformity of the embossing directly affect the finished quality of the waterproof roll. The common structure of the embossing device in the prior art is as follows: the device comprises a fixed driving roller and a movable driving roller; the movable driving roller is installed on the sliding block and can move in the sliding groove to adjust the gap between the movable driving roller and the fixed driving roller. The web passes through the gap between the two driven rollers to effect the embossing process, and thus control of the embossing depth, i.e. the gap. The control method according to the gap may be divided into a position control method and a pressure control method.

In the position control mode, a nut seat is arranged on the sliding block, and the nut seat drives the sliding block and the movable driving roller to move by manually rotating the lead screw. The amount of rotation of the threaded spindle is linearly converted into the amount of movement of the movable drive roller, i.e. the gap between the two drive rollers. The lead screw is fixed and the gap between the two driving rollers is also fixed. Therefore, by adopting a position control mode, the embossing device can accurately control the embossing depth of the waterproof roll. However, when the waterproof roll having an abnormal thickness passes through the embossing device (for example, a joint seam of the waterproof roll, a foreign matter on the surface, etc.), the waterproof roll cannot pass through the embossing device smoothly since the gap between the two driving rollers is fixed by the screw and the nut holder, and is broken.

In the pressure control mode, a compression spring is arranged on the sliding block, and the sliding block drives the movable driving roller to be tightly pressed on the surface of the coiled material through the elasticity of the compression spring. The elasticity of the compression spring is large, so that the gap between the two driving rollers is small, and the embossing depth of the waterproof roll is large. When the waterproof roll with abnormal thickness passes through the embossing device, because the gap between the two driving rollers is not fixed, the reaction force of the waterproof roll is greater than the elastic force of the compression spring, the movable driving rollers are bounced off, and the waterproof roll can pass through smoothly. Therefore, by adopting a pressure control mode, the embossing device can avoid the breaking accident of the waterproof roll. On the other hand, however, since the elastic force of the compression spring is not completely linearly converted into the gap between the two driving rollers, it is difficult to precisely control the embossing depth.

As an improvement, the embossing device adopting the pressure control mode uses the air cylinder to replace a compression spring, and the movable driving roller is pushed by the air cylinder to realize the embossing process. However, since the compressed air is unstable, the embossing is too deep when the air pressure is high, and the embossing is too shallow when the air pressure is low, the embossing depth is still difficult to realize accurate control. Therefore, neither the position-control type embossing apparatus nor the pressure-control type embossing apparatus can perform precise and stable embossing.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome at least one defect of the prior art and provides a servo coiled material embossing device which is used for solving the problems of coiled material breakage and embossing depth control in the embossing process and realizing stable and accurate embossing.

The utility model adopts the technical scheme that the servo web embossing device comprises a rack, a first embossing roller and a second embossing roller, wherein the first embossing roller and the second embossing roller are arranged on the rack, and a web penetrates through a gap between the first embossing roller and the second embossing roller. The embossing device also comprises a servo motor, a ball screw, a nut seat, a sensor and a pressure assembly which are arranged on the rack; the pressure assembly is connected with the first embossing roller, so that the first embossing roller can move relative to the second embossing roller and is pressed on the coiled material all the time; the ball screw or the nut seat is connected with the first embossing roller, and the nut seat is sleeved on the ball screw; a sensor measures a gap between the first patterned roll and the second patterned roll; the servo motor drives the rolling screw to rotate according to signals of the sensor, and a gap between the first embossing roller and the second embossing roller is adjusted.

The scheme takes the layout that the first embossing roller is movable, the second embossing roller is fixed, and the first embossing roller can move up and down relative to the second embossing roller as an example. The pressure assembly of the scheme can adopt the mechanism of the existing pressure control mode. A pressure assembly is connected to the first patterned roll that enables the first patterned roll to move up and down relative to the second patterned roll. The first embossing roll is pressed down against the web all the time under the downward force provided by the pressure assembly. The nut seat of the scheme is sleeved on the ball screw, and the nut seat and the ball screw can move in relative positions. After the ball screw or the nut seat is connected with the first embossing roller, the position of the first embossing roller, namely the gap between the first embossing roller and the second embossing roller, can be adjusted by rotating the ball screw or the nut seat. In order to make the position control and the pressure control work cooperatively, when the ball screw and the nut seat are respectively connected with the machine frame and the first embossing roller, one end of the ball screw and the nut seat are movably connected, and the other end of the ball screw and the nut seat are fixedly connected. Thus, the ball screw and nut seat provide only upward force to the first patterned roll and the pressure assembly provides only downward force to the first patterned roll. In the embossing process, the first embossing roller keeps balance under the acting force among the pressure assembly, the ball screw or the nut seat and the coil reaction, and the matching relation of the ball screw and the nut seat enables a set gap to be kept between the first embossing roller and the second embossing roller, namely, an ideal coil embossing depth value. When the web has an abnormal thickness, the reaction force of the web is greater than the downward force of the press assembly, and the first emboss roller can be sprung up. This scheme combines position control mode on pressure control mode's basis, and both modes cooperation work make embossing device both can control the knurling degree of depth of coiled material accurately, and coiled material that can the unusual thickness of self-adaptation again avoids the coiled material to break, realizes stably, embosses accurately.

The movable connection and the fixed connection here indicate whether the two can move relative to each other, for example: the ball screw is fixedly connected with the rack, and the position between the ball screw and the rack is fixed, but the ball screw can still rotate on the rack.

According to the scheme, the servo motor and the sensor are further added, closed-loop control of a gap between the first embossing roller and the second embossing roller is achieved, and the accuracy of embossing depth is improved. Under the downward acting force of the pressure assembly, the servo motor drives the ball screw to rotate, upward acting force is provided for the first embossing roller, the first embossing roller keeps a set position, and a set gap is kept between the first embossing roller and the second embossing roller. When the sensor measures that the gap becomes small, the servo motor drives the ball screw to rotate in the forward direction, the ball screw or the nut seat drives the first embossing roller to move upwards, the gap becomes large, and the gap is restored to the original set value. When the sensor measures that the gap is enlarged, the servo motor drives the ball screw to rotate reversely, under the downward acting force of the pressure assembly, the ball screw or the nut seat drives the first embossing roller to move downwards, the gap is reduced, and the gap is restored to the original set value.

It should be noted that the working principle of the embossing device is only specifically limited by the pressure assembly, the ball screw and the nut seat connected with the first embossing roller, the layout pattern of the first embossing roller and the second embossing roller is not limited by the working principle of the embossing device, and the scheme may also be that the first embossing roller is fixed, the second embossing roller is movable, the first embossing roller and the second embossing roller are arranged in the left and right directions, and the like.

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the utility model. For the purpose of better illustrating the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

As shown in fig. 1 and 2, a servo web embossing device includes a frame 10, a first embossing roller 20 and a second embossing roller 30, the first embossing roller 20 and the second embossing roller 30 being mounted on the frame 10, and a web passing through a space between the first embossing roller 20 and the second embossing roller 30. The embossing device also comprises a servo motor 41, a ball screw 42, a nut seat 43, a sensor and pressure assembly 50 which are arranged on the frame 10; a pressure assembly 50 is associated with the first embossing roller 20, enabling the first embossing roller 20 to move with respect to the second embossing roller 30 and to be pressed against the web at all times; the ball screw 42 or the nut seat 43 is connected with the first embossing roller 20, and the nut seat 43 is sleeved on the ball screw 42; a sensor measures the gap between the first patterned roll 20 and the second patterned roll 30; the servo motor 41 drives the roll screw to rotate according to the signal of the sensor, and adjusts the gap between the first emboss roller 20 and the second emboss roller 30.

This embodiment will be described by taking as an example a layout in which the first patterned roll 20 is movable, the second patterned roll 30 is fixed, and the first patterned roll 20 is movable up and down relative to the second patterned roll 30. The pressure assembly 50 of the present embodiment may employ a conventional pressure control mechanism. A pressure assembly 50 is connected to the first patterned roll 20, the pressure assembly 50 enabling the first patterned roll 20 to move up and down relative to the second patterned roll 30. The first patterned roll 20 is pressed down against the web all the time under the downward force provided by the pressure assembly 50. The nut seat 43 of the scheme is sleeved on the ball screw 42, and the ball screw and the nut seat can move relative to each other. After the ball screw 42 or the nut holder 43 is connected to the first embossing roll 20, the position of the first embossing roll 20, i.e. the gap between the first embossing roll 20 and the second embossing roll 30, can be adjusted by rotating the ball screw 42 or the nut holder 43. In order to make the position control and the pressure control work together, the ball screw 42 and the nut holder 43 are movably connected at one end and fixedly connected at the other end, respectively, to the frame 10 and the first embossing roller 20. Thus, the ball screw 42 and the nut seat 43 provide only an upward force to the first embossing roll 20 and the pressure assembly 50 provides only a downward force to the first embossing roll 20. During embossing, the first embossing roller 20 is kept in balance under the acting force of the pressure assembly 50, the ball screw 42 or the nut seat 43 and the web reaction, and the matching relationship of the ball screw 42 and the nut seat 43 keeps a set gap between the first embossing roller 20 and the second embossing roller 30, namely, a desired web embossing depth value. When the web has an abnormal thickness, the reaction force of the web is greater than the downward force of the pressing assembly 50, and the first emboss roller 20 can be sprung up. This scheme combines position control mode on pressure control mode's basis, and both modes cooperation work make embossing device both can control the knurling degree of depth of coiled material accurately, and coiled material that can the unusual thickness of self-adaptation again avoids the coiled material to break, realizes stably, embosses accurately.

The movable connection and the fixed connection here indicate whether the two can move relative to each other, for example: the ball screw 42 is fixedly connected to the frame 10, which means that the position between the ball screw 42 and the frame 10 is fixed, but the ball screw 42 can still rotate on the frame 10.

The scheme further adds the servo motor 41 and the sensor, realizes the closed-loop control of the gap between the first embossing roller 20 and the second embossing roller 30, and improves the accuracy of the embossing depth. Under the downward force of the pressure assembly 50, the servo motor 41 drives the ball screw 42 to rotate, so as to provide an upward force to the first embossing roller 20, the first embossing roller 20 keeps a set position, and a set gap is kept between the first embossing roller 20 and the second embossing roller 30. When the sensor measures that the gap becomes smaller, the servo motor 41 drives the ball screw 42 to rotate in the forward direction, the ball screw 42 or the nut seat 43 drives the first embossing roller 20 to move upward, the gap becomes larger, and the original set value is restored. When the sensor measures that the gap is increased, the servo motor 41 drives the ball screw 42 to rotate reversely, and under the downward acting force of the pressure assembly 50, the ball screw 42 or the nut seat 43 drives the first embossing roller 20 to move downward, so that the gap is decreased and is restored to the original set value.

The nut holder 43 is lapped on the frame 10. During normal operation, the servo motor 41 drives the ball screw 42 to rotate, the nut seat 43 is equivalently fixed on the frame 10 under the downward acting force of the pressure assembly 50 and the limit of the vertical edge 62 of the T-shaped connecting plate, the ball screw 42 drives the T-shaped connecting plate 60 and the first embossing roller 20 to move up and down, and the gap between the first embossing roller 20 and the second embossing roller 30 is adjusted.

The servo motor 41 and the ball screw 42 are mounted on the transverse edge 61 of the T-shaped connecting plate. The servo motor 41 includes a motor and a decelerator. The ball screw 42 passes downward through the T-shaped connecting plate 60, and the lower end thereof is fitted with a nut seat 43. The nut seat 43 overlaps the surface of the frame 10. The side of the nut seat 43 is attached to the vertical edge 62 of the T-shaped connecting plate.

In use, the compressed air is first adjusted to the maximum state, the air cylinder pushes the first embossing roll 20 to move downward approximately, and a certain pressure exists between the first embossing roll 20 and the second embossing roll 30. In normal operation, the servo motor 41 drives the ball screw 42 to rotate, and since the nut seat 43 is limited on the frame 10, the ball screw 42 drives the T-shaped connecting plate 60 and the first embossing roller 20 to move up and down, so as to precisely adjust the gap between the first embossing roller 20 and the second embossing roller 30. When the abnormal thickness of the coiled material occurs, the reaction force of the coiled material passing through is larger than the downward force of the air cylinder, the first embossing roller 20 is bounced upwards, the servo motor 41 and the ball screw 42 are also lifted upwards by the first embossing roller 20 through the T-shaped connecting plate 60, and the nut seat 43 is separated from the surface of the machine frame 10 contacted with the nut seat. After the coiled material with abnormal thickness passes through, the nut seat 43 falls back on the machine frame 10 under the downward force of the air cylinder, and returns to the normal working state.

Specifically, the input device and the sensor are electrically connected to the servo motor 41, the input device is a touch screen, and the sensor is an electronic ruler. The servo motor 41 automatically adjusts the gap between the first embossing roller 20 and the second embossing roller 30 by inputting the embossing depth of the web through the touch screen. An abnormal alarm value is set, automatic alarm reminding is carried out when the embossing depth is abnormal, and automation of control of the embossing depth of the coiled material can be achieved, so that the product quality problem is reduced, the production efficiency is improved, and the production cost is reduced.

Specifically, the electronic ruler is mounted on the movable connecting rod 51 and the fixed frame 10, and contacts the roll surfaces of the first embossing roll 20 and the second embossing roll 30, and is marked as a zero position, when the connecting rod 51 drives the first embossing roll 20 to move upwards, the electronic ruler measures the moving distance, namely the gap between the first embossing roll 20 and the second embossing roll 30, namely the embossing depth.

Specifically, the working process of this embodiment is as follows: the equipment is electrified, compressed air is connected, the air cylinder works, and the piston extends downwards; the embossing depth of the coiled material is set by the touch screen, the servo motor drives the ball screw to rotate, and the first embossing roller reaches a set position; the electronic ruler feeds back the position of the first embossing roller, and the servo motor automatically adjusts; the embossing device gives an alarm when the coiled material has abnormal thickness.
