The assembly comprises a first buffer assembly and a second buffer assembly disposed on the side wall of a base plate, the first buffer assembly being located on the side of the second buffer assembly away from the winding roller; the first buffer assembly comprises a fixed roller, a floating roller, and a first sensor, and the second buffer assembly comprises a fixed clamping roller group, a floating clamping roller group, and a second sensor.

Description

Technical Field

[0001] The invention relates to the technical field of coil tension control, in particular to an adaptive tension control component of cork coil calendering equipment. Background Art

[0002] The adaptive tension control component in the cork coil calendering equipment is a dynamic adjustment system. Its core function is to ensure that the cork coil always maintains a stable and appropriate tension during the production process (such as calendering, cooling, coiling, etc.), thereby avoiding material stretching deformation, breakage or wrinkling, and ensuring product quality and the stability of continuous production.

[0003] Current adaptive tension control systems typically consist of a floating roller and a sensor. The floating roller presses against the upper surface of the web (or against the lower surface of soft materials) and applies pressure to the web, forcing the area of ​​the web corresponding to the floating roller into a curved state. When the web tension is too high or too low, the curved portion of the web tightens or relaxes, causing the floating roller to move. The sensor then detects this displacement and controls the motor speed. However, current tension control systems can have the following problems in some scenarios:

[0004] When the coil breaks or separates from the previous process, the tension of the coil disappears due to the lack of restraining force at one end of the coil. This phenomenon causes the floating roller to reset. At this time, the sensor will still detect the displacement of the floating roller and continue to increase the motor speed to try to increase the tension of the coil. However, in this scenario, accelerated winding is likely to affect the quality of the coil and winding. Summary of the Invention

[0005] The purpose of the present invention is to provide an adaptive tension control component for cork coil calendering equipment, which controls the tension of the coil through a first buffer component and a second buffer component, thereby solving the problem raised in the above-mentioned background technology, namely, when the coil breaks or is separated from the previous process, the motor increases the speed to accelerate the winding, which is likely to affect the quality of the coil and the winding.

[0006] To achieve the above-mentioned purpose, the adaptive tension control assembly of the cork coil calendering equipment includes a first buffer assembly and a second buffer assembly arranged on the side wall of the base plate, wherein the first buffer assembly is located on the side of the second buffer assembly away from the winding roller; the first buffer assembly includes a fixed roller, a floating roller and a first sensor, and the second buffer assembly includes a fixed clamping roller group, a floating clamping roller group and a second sensor, wherein:

[0007] The fixed roller and the fixed clamping roller group rotate on the side wall of the base plate in a fixed manner, and the floating roller and the floating clamping roller group are fixed on the side wall of the fixed clamping roller group in a sliding manner;

[0008] The second buffer assembly further includes a limiting mechanism for limiting the sliding of the floating clamping roller group under normal conditions;

[0009] The first sensor is used to send a control signal to the limit mechanism to release the limit after a preset time period of displacement of the floating roller; the second sensor is used to send a signal to the motor of the corresponding winding roller to adjust the speed after the floating clamping roller group is displaced;

[0010] The first buffer assembly also includes an induction switch for monitoring the contact state between the coil and the floating roller. When the coil leaves the floating roller, the induction switch turns off the first sensor, so that the floating clamping roller group maintains the position before the coil leaves the floating roller.

[0011] In the above technical solution, the first buffer assembly controls the second buffer assembly, so the second buffer assembly is in a state of being immobile under normal conditions. In this way, when the coil leaves the floating roller, the second buffer assembly does not move, thereby avoiding the adjustment of the motor speed.

[0012] On this basis, the side wall of the base plate is provided with a through slide groove, a longitudinal slide column is provided in the slide groove, a mounting plate is provided on the outside of the slide column for sliding, and the top of the slide groove is elastically connected to the top of the mounting plate;

[0013] The second sensor is arranged at the bottom end of the slideway and is used to monitor the displacement of the mounting plate;

[0014] The floating clamping rod group is fixedly arranged on the side wall of the mounting plate, and the fixed clamping rod group is fixedly arranged on the side wall of the base plate below the slide groove.

[0015] On this basis, the limiting mechanism includes a push rod located on one side of the sliding column and a driving member for driving the push rod to contact or disengage from the sliding column, and the driving member is fixedly arranged at the bottom of the mounting plate; when the driving member receives a contact instruction issued by the first sensor, it drives the push rod to disengage from the sliding column.

[0016] This structural design puts the second buffer assembly in a restricted state. Only when the coil has not separated from the floating roller and the push rod is separated from the slide column, the motor will adjust the speed at this time.

[0017] On this basis, the induction switch is located below one side of the floating roller;

[0018] It also includes a sensing element fixedly mounted on the outer ring of the floating roller. The sensing element enters the monitoring area of ​​the sensing switch in a rotating state and leaves the monitoring area of ​​the sensing switch in a stationary state.

[0019] The sensor element can be out of the detection area of ​​the induction switch when the web leaves the floating roller. Through this design, it can be identified whether the web has left the floating roller.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the adaptive tension control component of the cork coil calendering equipment, two groups of tension detection mechanisms are set up, one of which is used to control the movement of the other group of tension detection mechanisms, and the other group of tension detection mechanisms is in a locked state under normal circumstances. When the coil breaks or separates from the previous process, the other group of tension detection mechanisms will not be released from the locked state, thereby avoiding the problem of increased winding speed.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Aiming at the problem that when the coil breaks or is separated from the previous process, the motor speed increases to accelerate the winding, which easily affects the coil and the quality of the winding, the present invention provides an adaptive tension control component for the cork coil calendering equipment. Figure 1 As shown, the tension control assembly includes a first buffer assembly (corresponding to Figure 1 Area A in the second buffer component (corresponding to Figure 1 In area B, the first buffer assembly is located on the side of the second buffer assembly away from the winding roller 200; wherein,

[0034] The first buffer assembly includes a fixed roller 160, a floating roller 140, and a first sensor 103. The second buffer assembly includes a fixed clamping roller group 110, a floating clamping roller group 120, and a second sensor 102. The fixed roller 160 and the fixed clamping roller group 110 rotate in a fixed manner on the side wall of the substrate 100, and the floating roller 140 and the floating clamping roller group 120 are fixed to the side wall of the fixed clamping roller group 110 in a sliding manner. The second buffer assembly also includes a limiting mechanism 130 for limiting the sliding of the floating clamping roller group 120 under normal conditions.

[0035] The first sensor 103 is used to send a control signal to the limit mechanism 130 to release the limit after a preset time period of displacement of the floating roller 140; the second sensor 102 is used to send a signal to adjust the speed of the motor of the corresponding winding roller 200 after the floating clamping roller group 120 is displaced;

[0036] The first buffer assembly also includes a sensor switch 104 for monitoring the contact state between the coil and the floating roller 140. When the coil is separated from the floating roller 140, the sensor switch 104 turns off the first sensor 103, so that the floating clamping roller group 120 maintains the position before the coil is separated from the floating roller 140.

[0037] In the above description, the preset time is the time the floating roller 140 controls the first sensor 103. It should be understood that the moment the web leaves the floating roller 140, the floating roller 140 begins to reset. At this time, the time the sensor switch 104 controls the first sensor 103 to turn off is likely to be earlier than the time the first sensor 103 sends a signal to the limit mechanism 130. For example, if the preset time is 5 seconds, the first sensor 103 will send a signal to the limit mechanism 130 5 seconds after the sensor switch 104 moves. However, if the sensor switch 104 detects the web leaving the floating roller 140 within these 5 seconds, it will deactivate the first sensor 103, and the first sensor 103 will no longer send a signal to the limit mechanism 130. This allows the limit mechanism 130 to continue to restrict the sliding of the floating clamping roller assembly 120, preventing displacement of the floating clamping roller assembly 120.

[0038] Specifically, the sidewall of the base plate 100 is provided with a through-going chute 101, within which a mounting plate 121 is longitudinally slidably mounted. Specifically, longitudinal slide posts 122 are provided at the left and right ends of the chute 101. These slide posts 122 slide through the mounting plate 121 to constrain the mounting plate 121 within the chute 101. The mounting plate 121 is lower than the height of the chute 101, ensuring sufficient space within the chute 101 to support the longitudinal sliding of the mounting plate 121. A tensioning spring 123 is elastically connected between the top of the chute 101 and the top of the mounting plate 121. Furthermore, a second sensor 102 is provided at the bottom end of the chute 101 to monitor the displacement of the mounting plate 121. Furthermore, a floating clamping rod assembly 120 is fixedly mounted on the sidewall of the mounting plate 121, while a fixed clamping rod assembly 110 is fixedly mounted on the sidewall of the base plate 100, below the chute 101.

[0039] like Figure 2 As shown, the limiting mechanism 130 includes a push rod 131 located on one side of the sliding column 122 and a driving member for driving the push rod 131 to contact or disengage from the sliding column 122, and the driving member is fixedly arranged at the bottom of the mounting plate 121. The driving member can be an electric push rod, a cylinder 132, a cam mechanism, etc. Under normal circumstances, the driving member drives the push rod 131 to contact the sliding column 122, thereby increasing the resistance to the movement of the mounting plate 121 and limiting the movement of the mounting plate 121. When the driving member receives the contact instruction issued by the first sensor 103, the driving member drives the push rod 131 to disengage from the sliding column 122, and the restriction on the movement of the mounting plate 121 is released. Here, the end of the push rod 131 that contacts the sliding column 122 is preferably made of rubber. Rubber has strong elasticity and friction, which can improve the stability during the restriction process.

[0040] In addition, in order to prevent the push rod 131 from deflecting when contacting the sliding column 122, the present invention further provides a sleeve 133 fixedly provided at the bottom of the mounting plate 121 and slidably sleeved on the outer ring of the sliding column 122. A convex tube for the push rod 131 to extend into is provided on one side of the sleeve 133 corresponding to the push rod 131, thereby limiting the deflection of the push rod 131.

[0041] Figure 3 The detailed structure of the fixed clamping roller assembly 110 and the floating clamping roller assembly 120 is shown. As shown, both the fixed clamping roller assembly 110 and the floating clamping roller assembly 120 include a first roller 111, a second roller 112, and a mounting base 113. The first roller 111 is fixedly rotatably connected to the mounting base 113, while the second roller 112 is longitudinally slidably rotatably connected to the mounting base 113. Specifically, a slider 114 is rotatably connected to one end of the first roller 111. The slider 114 slides longitudinally within a slideway provided on the side wall of the mounting base 113. A connecting spring 115 is provided between the slider 114 and the side wall of the mounting base 113, elastically connecting the two. This design allows the connecting spring 115 to use its elasticity to press the second roller 112 against the top of the first roller 111. The first and second rollers 111 and 112 then cooperate to clamp the web. As the web moves, friction causes the first and second rollers 111 and 112 to rotate.

[0042] It can be understood that the structures of the fixed clamping rod group 110 and the floating clamping rod group 120 are basically the same, and the difference lies in the positional relationship between the two. Therefore, when the first roller 111, the second roller 112 and the mounting base 113 are mounted on the side wall of the base plate 100, it is the fixed clamping rod group 110, and when the first roller 111, the second roller 112 and the mounting base 113 are mounted on the side wall of the mounting plate 121, it is the floating clamping rod group 120. At the same time, the fixed clamping rod group 110 and the floating clamping rod group 120 are staggered (for details, refer to Figure 1 ).

[0043] Figure 4 The specific structure of the floating roller 140 is shown. As shown in the figure, one end of the floating roller 140 is rotatably connected to a slide plate 141. The slide plate 141 slides longitudinally in a slide hole provided on the side wall of the substrate 100, and a first sensor 103 is provided at the bottom of the slide hole to monitor the displacement of the slide plate 141. At the same time, a compression spring 142 is provided between the slide plate 141 and the side wall of the substrate 100 to elastically connect the two. Then, combined with Figure 1 As shown, the fixed rollers 160 are located on both sides above the floating roller 140. The floating roller 140 and the fixed rollers 160 together constitute a first buffer assembly.

[0044] In the present invention, the induction switch 104 monitors the contact state between the web and the floating roller 140 through the induction member 150. Figure 1As shown, the sensor switch 104 is located below one side of the floating roller 140; the sensor 150 is mounted on the outer ring of the floating roller 140 and is configured to rotate with the floating roller 140. When the web drives the floating roller 140 to rotate, the sensor 150 enters the monitoring area of ​​the sensor switch 104. When the web separates from the floating roller 140, causing the floating roller 140 to stop rotating, the sensor 150 leaves the monitoring area of ​​the sensor switch 104, and the sensor switch 104 turns off the first sensor 103.

[0045] like Figure 4 As shown, in some embodiments, the induction member 150 includes a convex plate 151 fixedly mounted on one end of the outer ring of the floating roller 140. Figure 5 shown. Figure 5 The left half of the figure shows the state when the web has not yet separated from the floating roller 140. At this time, the web drives the floating roller 140 to rotate, and the floating roller 140 drives the convex plate 151 to rotate. During the rotation process, the convex plate 151 continuously enters the monitoring area of ​​the induction switch 104 (the area indicated by the dotted arrow). At this time, the induction switch 104 does not turn off the first sensor 103. Figure 5 The right half shows the state when the coil is separated from the floating roller 140. The separation of the coil causes the floating roller 140 to stop rotating. Since the weight of the part where the floating roller 140 is connected to the convex plate 151 is large, the convex plate 151 is facing downward under the action of gravity. At this time, the convex plate 151 cannot enter the monitoring area of ​​the induction switch 104, and the induction switch 104 turns off the first sensor 103.

[0046] like Figure 6-Figure 7 As shown, in other embodiments, the induction member 150 includes a plurality of sleeves 152 fixedly arranged on the outer ring of the floating roller 140, and the plurality of sleeves 152 are arranged equidistantly. A slide rod 153 is slidably arranged at one end of the sleeve 152, and the slide rod 153 is connected to the sleeve 152 via a return spring 154. In this embodiment, first, as shown in FIG. Figure 6 As shown in the left half of the figure, when the coil has not yet separated from the floating roller 140, the floating roller 140 drives the multiple sleeves 152 to rotate, and the centrifugal force generated by the rotation overcomes the elasticity of the return spring 154, causing the slide bar 153 to be thrown out. At this time, the thrown slide bar 153 enters the monitoring area of ​​the sensor switch 104. At this time, the sensor switch 104 will not turn off the first sensor 103; then Figure 6 As shown in the right half of , when the coil is separated from the floating roller 140 , the floating roller 140 stops rotating, causing the return spring 154 to rebound and pull the slide bar 153 back into the sleeve 152 , at which time the slide bar 153 is separated from the monitoring area of ​​the induction switch 104 .

[0047] That is to say, by setting up two groups of tension detection mechanisms, one group of tension detection mechanisms is used to control the movement of the other group of tension detection mechanisms, and the other group of tension detection mechanisms is in a locked state under normal circumstances, so that when the coil breaks or separates from the previous process, the other group of tension detection mechanisms will not be released from the locked state, thereby avoiding the problem of increasing the winding speed.

[0048] The working principle of the tension control component is described in detail below:

[0049] First, if Figure 1 As shown, the coil is sequentially wound around the top of the first fixed roller 160, the bottom of the floating roller 140, and the top of the second fixed roller 160. The coil then passes through the floating clamping roller assembly 120 and the fixed clamping roller assembly 110 in sequence, and finally enters the winding roller 200. Under normal tension, the coil pulls the floating roller 140 to the middle of the slide hole, compressing the compression spring 142. At the same time, it pulls the floating clamping roller assembly 120 downward, at which time the tension spring 123 is in a stretched state.

[0050] When the web tension decreases, the compression spring 142 drives the floating roller 140 downward. The first sensor 103 detects the downward movement of the floating roller 140 and, after a preset time, sends a release signal to the limit mechanism 130, causing the stopper 131 to disengage from the slide post 122. As the tension decreases, the tension spring 123 rebounds, pulling the mounting plate 121 upward. When the second sensor 102 detects the upward movement of the mounting plate 121, it sends a signal to the motor of the corresponding winding roller 200, driving the winding roller 200 to increase its speed, increasing the web tension and returning the floating roller 140 and the floating clamping roller assembly 120 to their pre-tension position.

[0051] When the web tension increases, the web overcomes the elasticity of the compression spring 142, causing the compression spring 142 to continue compressing and moving the floating roller 140 upward. The first sensor 103 detects the upward movement of the floating roller 140 and, after a preset time, sends a release signal to the limit mechanism 130, causing the stopper 131 to disengage from the slide post 122. As the web tension increases, the web also overcomes the elasticity of the tension spring 123, pulling the mounting plate 121 downward. When the second sensor 102 detects the downward movement of the mounting plate 121, it sends a signal to the motor of the corresponding winding roller 200, driving the winding roller 200 to reduce its speed, reducing the web tension and returning the floating roller 140 and the floating clamping roller assembly 120 to their positions before the increased tension.

[0052] like Figure 8As shown, when the coil is separated from the floating roller 140 (reference position a), the floating roller 140 stops rotating, causing the inductive switch 104 to fail to detect the presence of the inductive member 150. At this time, the inductive switch 104 turns off the first sensor 103. In this way, the limiting mechanism 130 does not receive the contact signal, thereby continuing to limit the mounting plate 121 (reference position b). At this time, the mounting plate 121 does not move, and the winding roller 200 maintains the original speed to wind the coil. During the winding process, the first roller 111 and the second roller 112 clamp the coil to ensure the stability and quality of the winding.

[0053] It should be understood that the second sensor 102 and the first sensor 103 may be displacement sensors, laser sensors, or other types of sensors. The second sensor 102, the first sensor 103, and the inductive switch 104 may also be connected to a common controller for control. For example, after obtaining displacement data of the floating roller 140 from the first sensor 103, the controller controls the limiting mechanism 130 to release the restriction. The controller then obtains data from the second sensor 102 to control the motor of the corresponding winding roller 200. If the controller detects that the inductive switch 104 cannot detect a signal from the sensing element 150, it controls the limiting mechanism 130 to continue restricting the position.

[0054] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
