Description

Technical Field

[0001] This utility model relates to the technical field of impregnation treatment, and in particular to a roller gap adjustment device for impregnation treatment. Background Technology

[0002] In the field of impregnation (or coating technology), after fabric has undergone a coating process using a coating material, it needs to pass through metering rollers to remove excess coating material from its surface to produce a finished product that meets predetermined specifications. In common fabric winding mechanisms that include metering rollers, cylinders are typically used as a power source to drive the metering rollers to move relative to each other, thereby adjusting the gap between the two metering rollers. This ensures that after the fabric coated with the material passes between the two metering rollers, its surface has a coating thickness that meets predetermined specifications.

[0003] In the production process, fabric is made by stringing together multiple pieces of fabric. At the junction of two adjacent pieces of fabric (commonly known as the "fabric end"), the two pieces of fabric overlap. It's conceivable that the fabric at this junction is thicker than at other points. Therefore, when the junction passes through the gap between two metering rollers, the two rollers need to adjust the gap in response to this thickness difference.

[0004] In common fabric winding mechanisms that include metering rollers, cylinders are typically used as the power source to drive the metering rollers to move relative to each other, thereby adjusting the gap between the two metering rollers. However, when using cylinders as the power source to control the roller gap, due to the mechanical characteristics of the cylinders, there may be an error between the actual gap and the expected gap between the two rollers. Therefore, in the production process, when the actual gap between the two rollers is smaller than the expected gap, the fabric will be squeezed as it passes through the two rollers, affecting the smoothness of fabric pulling or guiding. Conversely, when the actual gap between the two rollers is larger than the expected gap, the fabric will experience insufficient friction as it passes through the two rollers, resulting in a decrease in fabric pulling force. In other words, if the gap between the two rollers of the fabric winding mechanism cannot be precisely adjusted to match the thickness of the fabric, significant differences will occur in fabric pulling or guiding, affecting the smoothness of the production process and potentially leading to defects in the final product.

[0005] Therefore, how to design a roller gap adjustment device for impregnation treatment, so as to accurately control the position of the metering roller to adjust the predetermined gap between the two rollers, and thus solve the technical problems in the prior art, is an important research topic of the inventor of this utility model.

As used in this specification and / or the appended claims, the singular forms “a” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0027] Please refer to the following: Figure 1 and Figure 2 These are a block diagram and a schematic diagram of the device, respectively, of the first embodiment of the roller gap adjustment device for impregnation treatment of this utility model.

[0028] As shown in the figure, the roller gap adjustment device 1 for impregnation treatment of this utility model is applied to the first roller 91 and the second roller 92 to adjust or correct the gap between the first roller 91 and the second roller 92; preferably, the roller gap adjustment device 1 for impregnation treatment of this utility model is applied to a metering roller group. The first roller 91 and the second roller 92 are located on the fabric conveying path P and are arranged at intervals along the roller arrangement direction D; wherein, the roller arrangement direction D is not parallel to the conveying direction of the fabric conveying path P; preferably, the roller arrangement direction D is perpendicular to the conveying direction of the fabric conveying path P. It is worth mentioning that there is a first gap G1 between the first roller 91 and the second roller 92; the first gap G1 is, for example, the sum of the fabric and coating thicknesses. The roller gap adjustment device 1 for impregnation treatment of this utility model mainly includes a gap adjustment module 11, a feature detection unit 12, and a control module 13.

[0029] In this configuration, the gap adjustment module 11 is connected to either the first roller 91 or the second roller 92, thereby configuring the gap adjustment module 11 to adjust the first gap G1 to a second gap G2, where the second gap G2 is larger than the first gap G1. For example, the first roller 91 is mounted on a fixed roller base; the second roller 92 is mounted on a movable roller base, and can be positioned away from or closer to the first roller 91 in the roller arrangement direction D; the gap adjustment module 11 is connected to the second roller 92 to drive or move the second roller 92. Alternatively, the second roller 92 is mounted on a fixed roller base; the first roller 91 is mounted on a movable roller base, and can be positioned away from or closer to the second roller 92 in the roller arrangement direction D; the gap adjustment module 11 is connected to the first roller 91 to drive or move the first roller 91. Preferably, the gap adjustment module 11 can be an explosion-proof servo motor, which can be connected to the first roller 91 or the second roller 92 via a linkage; wherein the linkage can be formed by any combination of components such as a screw, nut, gear, and rack. Incidentally, the gap adjustment module 11 can be connected to both ends of the first roller 91 or the second roller 92, thereby smoothly or precisely driving or moving the first roller 91 or the second roller 92. Furthermore, the movable roller base can be displaced in the roller arrangement direction D, for example, by the cooperation of a slide rail and a groove.

[0030] In different embodiments, there may be two gap adjustment modules 11, which are respectively connected to the first roller 91 and the second roller 92. The first roller 91 and the second roller 92 may be respectively mounted on a movable roller base, and the two gap adjustment modules 11 are respectively connected to the two movable roller bases, thereby driving the first roller 91 and the second roller 92 respectively. Thus, the roller gap adjustment device 1 for impregnation treatment in this invention can quickly and accurately adjust the gap between the first roller 91 and the second roller 92 according to actual process requirements (e.g., different first gaps).

[0031] The feature detection unit 12 is configured to detect features of the fabric on the fabric conveying path P to generate a feature detection signal 121. The feature detection unit 12 may be, for example, an infrared detection unit, a camera unit, or other similar components. Preferably, the feature of the fabric may be a fabric end, which is the overlapping and fixed connection point between the tail end of the previous fabric and the head end of the next fabric.

[0032] The control module 13 is electrically connected to the gap adjustment module 11 and the feature detection unit 12. The control module 13 may be a central processing unit (CPU), microcontroller unit (MCU), microprocessor, programmable controller, application-specific integrated circuit (ASIC), computing logic unit (ALU), complex programmable logic device (CPLD), field-programmable gate array (FPGA), system-on-a-chip (SoC), or other similar components or combinations thereof. The control module 13 may have storage or registers, which may be random access memory (RAM), read-only memory (ROM), such as electrically erasable programmable read-only memory (EEPROM), etc. The control module 13 receives the feature detection signal 121 and controls the operation of the gap adjustment module 11 accordingly.

[0033] Furthermore, the feature detection unit 12 is preferably located on the fabric conveying path P, and is spaced a predetermined distance S1 from the first roller 91 and the second roller 92. After receiving the feature detection signal 121, the control module 13 can control the gap adjustment module 11 to adjust the first gap G1 to the second gap G2 based on the predetermined distance S1, the fabric conveying speed V, and the stroke speed of the gap adjustment module 11. The predetermined distance S1 can be adjusted according to actual application, for example, by setting a distance that is easy to calculate based on the number of teeth or the tooth ratio of the gap adjustment module 11. The second gap G2 can be configured according to the thickness of the fabric. That is, after the fabric head passes through the feature detection unit 12, the control module 13 can use the predetermined distance S1 and the fabric conveying speed V to calculate the time when the fabric head passes through or reaches the same central axis of the first roller 91 and the second roller 92. Then, at the corresponding time, the gap adjustment module 11 adjusts the first gap G1 of the first roller 91 and the second roller 92 to the second gap G2 so that the fabric head can pass smoothly through the first roller 91 and the second roller 92 (or: passing the fabric head).

[0034] After the second gap G2 maintains a conveying distance S2, the control module 13 controls the gap adjustment module 11 to adjust the second gap G2 to the first gap G1. The conveying distance S2 is the distance calculated from the point between the first roller 91 and the second roller 92 (e.g., the position of the first roller 91 and the second roller 92 along the same central axis). The conveying distance S2 can be calculated based on the fabric conveying speed V and the stroke speed of the gap adjustment module 11 to obtain a time value, so that the control module 13 can control the gap adjustment module 11 to operate at the corresponding time value. Alternatively, a detector similar to or the same as the feature detection unit 12 can be provided on the conveying distance S2, which, after detecting a fabric end, is controlled by the control module 13 to operate the gap adjustment module 11. Incidentally, the conveying distance S2 is configured according to the length of the feature (fabric end).

[0035] Please see Figure 3 and Figure 4 These are block diagrams and device diagrams of the second embodiment of the roller gap adjustment device for impregnation treatment of this utility model. In this embodiment, the components with the same component symbols are configured and operate in the same or similar manner as in the aforementioned embodiments, and the similarities or similarities will not be repeated here.

[0036] As shown in the figure, in this embodiment, the roller gap adjustment device 1 for impregnation treatment of this utility model includes a gap detection unit 14. The gap detection unit 14 may be, for example, an infrared detection unit, a camera unit, or other components, which is electrically connected to the control module 13 and configured to detect the gap between the first roller 91 and the second roller 92 to generate a gap detection signal 141.

[0037] In this invention, the control module 13 adjusts the first gap G1 between the first roller 91 and the second roller 92 to a second gap G2 at a corresponding time, controlled by the gap adjustment module 11. At this time, the control module 13 further receives a gap detection signal 141 to determine whether the gap between the first roller 91 and the second roller 92 conforms to the second gap G2. When the control module 13 determines that the gap detection signal 141 does not conform to the second gap G2, the control module 13 controls the gap adjustment module 11 to adjust, correct, and compensate the gap between the first roller 91 and the second roller 92, so that the gap between the first roller 91 and the second roller 92 is transformed into the second gap G2. Therefore, this invention ensures that the correct or appropriate gap (second gap G2) is used for the fabric feeding process.

[0038] Furthermore, when the second gap G2 maintains the conveying distance S2 calculated from the first roller 91 and the second roller 92, the control module 13 controls the gap adjustment module 11 to adjust the second gap G2 to the first gap G1. At this time, the control module 13 receives the gap detection signal 141 to determine whether the gap between the first roller 91 and the second roller 92 conforms to the first gap G1. When the control module 13 determines that the gap detection signal 141 does not conform to the first gap G1, the control module 13 controls the gap adjustment module 11 to adjust, correct, and compensate the gap between the first roller 91 and the second roller 92, so that the gap between the first roller 91 and the second roller 92 is transformed into the first gap G1. In this way, the present invention can ensure that coating is performed with a correct or appropriate gap (first gap G1), thereby giving the fabric a correct or appropriate coating thickness. When the control module 13 receives the gap detection signal 141 and determines that the gap detection signal 141 does not conform to the first gap G1, the control module 13 controls the gap adjustment module 11 to adjust the gap between the first roller 91 and the second roller 92 to the first gap G1. For example, the control module 13 controls the gap adjustment module 11 to correct or compensate for the difference between the gap detection signal 141 and the first gap G1 to ensure that the gap between the first roller 91 and the second roller 92 is the first gap G1.

[0039] Incidentally, the location of the gap detection unit 14 can be configured according to the actual application, and its purpose is to detect the gap between the first roller 91 and the second roller 92. Therefore, it should not be limited to the example shown in the embodiment.

[0040] Preferably, whenever the control module 13 controls the gap adjustment module 11 to adjust the second gap G2 to the first gap G1, the control module 13 can control the gap detection unit 14 to detect the gap between the first roller 91 and the second roller 92 to obtain a gap detection signal 141, and then determine whether correction or compensation is needed. In different embodiments, the control module 13 can also control the gap detection unit 14 to detect the gap between the first roller 91 and the second roller 92 at regular intervals.

[0041] In summary, the roller gap adjustment device for impregnation processing of this utility model utilizes a gap adjustment module disposed on the first roller and / or the second roller, and uses an explosion-proof servo motor as the motor component to drive and push the movable roller base to move in the roller arrangement direction, thereby causing the roller to move as well, and thus adjusting the predetermined gap between the first roller and the second roller. Furthermore, because the roller gap adjustment device for impregnation processing of this utility model uses an explosion-proof servo motor as the motor component, it has the characteristics of high control precision and fast response speed, and also has explosion-proof function, thus precisely ensuring that there is a first gap or a second gap between the first roller and the second roller.

[0042] By means of the roller gap adjustment device for impregnation processing of this utility model, the gap between the first roller and the second roller can be quickly and accurately adjusted according to actual process requirements. This allows the fabric with coating material on its surface after the coating process to pass smoothly between the first roller and the second roller, and its surface can have a coating material thickness that meets the predetermined specifications. This effectively improves the smoothness of the production process and significantly increases the yield of the final product. In addition, the roller gap adjustment device for impregnation processing of this utility model can be combined with a feature detection unit to detect the fabric end and automatically adjust the gap between the two rollers based on the feature detection signal, thereby achieving the effect of automated production. Furthermore, the roller gap adjustment device for impregnation processing of this utility model may include a gap detection unit, which can confirm or check whether the gap between the first roller and the second roller is the first gap after the gap adjustment module returns the two rollers to the first gap. This allows the control module to make corresponding compensation or correction to ensure that the gap between the first roller and the second roller is the first gap. Therefore, this invention can ensure smooth production operations and prevent product defects caused by insufficient fabric pulling force or compression, significantly reducing product loss rate and improving product yield.
