Description

Technical Field

[0001] This utility model relates to the field of ribbon production equipment, and in particular to an automatic ribbon inspection and calendering device. Background Technology

[0002] In automated ribbon production lines, after stretching, the ribbon typically undergoes calendering. This process utilizes the mechanical pressure generated by the pressure rollers in a calendering machine, and takes advantage of the ribbon's plasticity under certain temperature conditions, to calender the surface and improve the overall smoothness and flatness of the ribbon. Existing calendering machines generally have two pressure rollers arranged vertically, with an adjustable gap between them. For example, Chinese utility model patent CN219032773U describes a method where a handwheel drives a screw to adjust the gap between the two pressure rollers.

[0003] Because there are joints at intervals on the webbing, and the thickness at the joint is greater than that at other parts of the webbing, and existing webbing calenders cannot dynamically adjust the spacing between the upper and lower pressure rollers according to the position of the webbing joints during the production process, the webbing joints are forced through the calender, which may cause webbing breakage, production stoppage, damage to the calender rollers, and other problems.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic detection and calendering device for webbing, which can solve the technical problem that existing webbing calendering machines cannot dynamically adjust the spacing between the upper and lower pressure rollers according to the position of the webbing joint during the production process, which may lead to webbing breakage, production stoppage, damage to the calendering rollers, and other situations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An automatic detection and calendering device for webbing includes a control component, a joint detection mechanism, and a calendering mechanism located downstream of the joint detection mechanism. Both the joint detection mechanism and the calendering mechanism are controlled and connected to the control component.

[0008] The calendering mechanism includes a first frame, on which an upper pressure roller and a lower pressure roller are rotatably mounted. The upper pressure roller and / or the lower pressure roller can move up and down relative to the first frame. A drive assembly for driving the upper pressure roller and / or the lower pressure roller to move up and down is connected to the upper pressure roller and / or the lower pressure roller.

[0009] The joint detection mechanism includes a second frame, a support roller, a first swing frame, and a proximity switch. The middle part of the first swing frame is hinged to the second frame. The two ends of the first swing frame are the detection end and the sensing end, respectively. The support roller is set on the second frame and can contact the detection end. The webbing passes between the detection end and the support roller. The proximity switch is set on the second frame and is used to detect whether the sensing end moves up and down.

[0010] Furthermore, the drive assembly includes two servo electric cylinders, which are located on both sides of the top of the first frame, and the output ends of the two servo electric cylinders are respectively connected to the two ends of the upper pressure roller.

[0011] Furthermore, sliders are provided at both ends of the upper pressure roller, and slide rails are provided on both sides of the first frame. The sliders are slidably mounted on their corresponding slide rails, and the output ends of the two servo electric cylinders are respectively connected to the sliders at both ends.

[0012] Furthermore, the calendering mechanism also includes a limiting component, which includes a mounting plate disposed at the entrance end of the first frame, and two limiting rods disposed in the mounting plate, the distance between the two limiting rods being adjustable.

[0013] Furthermore, a rotatable sleeve is fitted onto the outer surface of the limiting rod.

[0014] Furthermore, the first swing frame includes connecting plates on both sides and connecting rods at both ends of the connecting plates. A detection pressure roller is rotatably mounted on the connecting rod at the detection end, and the detection pressure roller can contact the support roller.

[0015] Furthermore, a rotating rod is connected to the middle of the two connecting plates, and the two ends of the rotating rod are rotatably connected to the second frame.

[0016] Furthermore, it also includes a tension adjustment mechanism, with the webbing passing through a joint detection mechanism, a tension adjustment mechanism, and a calendering mechanism in sequence.

[0017] The beneficial effects of this utility model are as follows:

[0018] The splice detection mechanism detects splices on the webbing in advance and feeds back the detection results to the control component. The control component then controls the drive component in the calendering mechanism to operate. When the splice passes through the calendering mechanism, the distance between the upper and lower pressure rollers in the calendering mechanism is increased to facilitate the smooth passage of the splice. After the splice passes through the calendering mechanism, the control component controls the drive component to operate again, reducing the distance between the upper and lower pressure rollers. In this way, the distance between the upper and lower pressure rollers is dynamically adjusted according to the position of the splice during the production process. This avoids the splice forcing its way through the calendering mechanism, which could cause webbing breakage, production stoppage, and damage to the calendering rollers, thus greatly reducing the scrap rate.

Detailed Implementation

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figures 1 to 4 As shown, the present invention provides an automatic detection and calendering device for webbing, including a control component, a joint detection mechanism 1, and a calendering mechanism 2 located downstream of the joint detection mechanism 1. Both the joint detection mechanism 1 and the calendering mechanism 2 are respectively controlled and connected to the control component.

[0027] The calendering mechanism 2 includes a first frame 21, on which an upper pressure roller 22 and a lower pressure roller 23 are rotatably mounted. The upper pressure roller 22 and / or the lower pressure roller 23 can move up and down relative to the first frame 21. A drive assembly for driving the upper pressure roller 22 and / or the lower pressure roller 23 to move up and down is connected to the upper pressure roller 22 and / or the lower pressure roller 23.

[0028] The joint detection mechanism 1 includes a second frame 11, a support roller 12, a first swing frame 13, and a proximity switch 14. The middle part of the first swing frame 13 is hinged to the second frame 11. The two ends of the first swing frame 13 are the detection end and the sensing end, respectively. The support roller 12 is set on the second frame 11 and can contact the detection end. The webbing 10 passes through the detection end and the support roller 12. The proximity switch 14 is set on the second frame 11 and is used to detect whether the sensing end moves up and down.

[0029] In actual use, the webbing processed by the drawing mechanism 4 enters the joint detection mechanism 1. The joint detection mechanism 1 adopts a seesaw structure. Under no external force, the sensing end of the first swing frame 13 is raised upward, and the detection end is pressed downward until it contacts the surface of the support roller 12. The webbing 10 passes between the detection end and the support roller 12, that is, the upper surface of the webbing 10 contacts the detection end and the lower surface contacts the support roller 12. When the non-joint position of the webbing passes between the detection end and the support roller 12, since the thickness of the non-joint position is almost uniform, the first swing frame 13 will not swing. When the sensing end hardly moves, the proximity switch does not detect any movement signal. When the webbing joint passes between the sensing end and the support roller 12, the thickness at the joint is twice that at the non-joint position. Therefore, the joint will push the sensing end upward, and the sensing end will move downward accordingly. At this time, the proximity switch 14 can detect the movement signal of the sensing end and sends the detection signal to the control component. After receiving the signal, the control component determines the movement signal based on the webbing length between the joint detection mechanism 1 and the calendering mechanism 2 and the webbing transmission speed. The time required for the webbing splice position to reach the calendering mechanism 2 is calculated. Based on the calculation result, the drive component in the calendering mechanism 2 is controlled to operate at the corresponding time point, adjusting the relative position between the upper pressure roller 22 and the lower pressure roller 23 to increase the distance between them, thereby allowing the splice position to pass smoothly through the calendering mechanism 2. When the splice position of the webbing 10 has completely passed between the detection end and the support roller 12, that is, when the non-splice position of the webbing 10 is located between the detection end and the support roller 12, due to the reduced thickness of the webbing 10, the detection end, due to its own gravity, will... As the sensor moves downward, it moves upward accordingly. At this time, the proximity switch 14 can also detect the movement signal of the sensor. The proximity switch 14 sends the detection signal to the control component. After receiving the signal, the control component calculates the time required for the webbing joint to completely pass through the calendering mechanism 2 based on the webbing length between the joint detection mechanism 1 and the calendering mechanism 2 and the webbing transmission speed. Based on the calculation result, the control component controls the drive component in the calendering mechanism 2 to act again at the corresponding time point, reducing the distance between the upper pressure roller 22 and the lower pressure roller 23 to perform normal calendering processing on the non-joint position.

[0030] In this embodiment, the splice detection mechanism 1 detects the splice on the webbing in advance, and the splice detection mechanism 1 feeds back the detection structure to the control component. The control component controls the drive component in the calendering mechanism 2 to operate. When the splice passes through the calendering mechanism 2, the distance between the upper pressure roller 22 and the lower pressure roller 23 in the calendering mechanism 2 is increased so that the splice can pass through the calendering mechanism 2 smoothly. After the splice passes through the calendering mechanism 2, the control component controls the drive component to operate again to reduce the distance between the upper pressure roller 22 and the lower pressure roller 23. In this way, the distance between the upper and lower pressure rollers is dynamically adjusted according to the position of the splice during the production process, avoiding the splice from forcing its way through the calendering mechanism 2 and causing the webbing to break, production to stop, and the calendering roller to be damaged, which greatly reduces the scrap rate.

[0031] Furthermore, such as Figure 4 As shown, the drive assembly includes two servo cylinders 24, which are located on both sides of the top of the first frame 21, and their output ends are respectively connected to both ends of the upper pressure roller 22. In this embodiment, the drive assembly is connected to the upper pressure roller 22, and the drive assembly drives the upper pressure roller 22 to move up and down, thereby adjusting the distance between the upper and lower pressure rollers. Specifically, the servo cylinders 24 are used as the drive assembly, which can precisely control the position of the upper pressure roller 22, thereby precisely controlling the distance between the upper and lower pressure rollers.

[0032] In other embodiments, a drive assembly can be connected to the lower pressure roller 23, and the lower pressure roller 23 can be moved up and down by the drive assembly to adjust the distance between the upper and lower pressure rollers.

[0033] Furthermore, such as Figure 4 As shown, both ends of the upper pressure roller 22 are provided with sliders 25, and both sides of the first frame 21 are provided with slide rails 26. The sliders 25 are slidably mounted on their corresponding slide rails 26. The output ends of the two servo cylinders 24 are respectively connected to the sliders 25 at both ends. Specifically, each side of the first frame 21 is provided with two slide rails 26, and the two slide rails 26 are correspondingly positioned on both sides of the slider 25. Both sides of the slider 25 are provided with slots that cooperate with the slide rails 26. Through the cooperation of the slide rails 26 and the sliders 25, the movement direction of the upper pressure roller 22 is ensured.

[0034] Furthermore, such as Figure 4As shown, the calendering mechanism 2 also includes a limiting component, which includes a mounting plate 27 disposed at the entrance end of the first frame 21. Two limiting rods 28 are disposed in the mounting plate 27, and the distance between the two limiting rods 28 is adjustable. Preferably, a rotatable sleeve 29 is fitted onto the outer surface of the limiting rod 28. In actual use, the distance between the two limiting rods 28 is adjusted according to the specific width of the webbing 10, thereby limiting the position of the webbing 10 entering the calendering mechanism 2 and ensuring that the webbing 10 is calendered in the appropriate position. Furthermore, the rotatable sleeve 19 on the outer surface of the limiting rod 28 reduces the friction between the webbing 10 and the limiting rod 28 during movement, preventing wear on both sides of the webbing 10.

[0035] Furthermore, such as Figure 2-3 As shown, the first swing frame 13 includes connecting plates 131 on both sides and connecting rods 132 at both ends of the connecting plates 131. A detection pressure roller 133 is rotatably mounted on the connecting rod 132 at the detection end, and the detection pressure roller 133 can contact the support roller 12. Specifically, the first swing frame 13 is rectangular. On the top of the second frame 11, along the direction close to the calendering mechanism 2, mounting seats 1-15, 16-2, and 17-3 are arranged sequentially. There are two mounting seats 1, 2, and 3 on each side of the second frame 11. At least one mounting seat 15 is equipped with a proximity switch 14. The sensing end is movably positioned between the two mounting seats 15. This arrangement allows the proximity switch 14 to accurately detect whether the sensing end has moved, thereby sending an accurate signal to the control component. The two sides of the middle part of the first swing frame 13 are hinged to the two mounting seats 2-16 respectively. Preferably, a rotating rod 134 is also connected to the middle part of the two connecting plates 131, and the two ends of the rotating rod 134 are rotatably connected to the second frame 11. Specifically, the two ends of the rotating rod 134 extend to the outside of the two connecting plates 131 and are rotatably connected to the two mounting bases 16 respectively. The two ends of the support roller 12 are rotatably mounted on the two mounting bases 17 respectively, and the support roller 12 is correspondingly positioned below the detection pressure roller 133.

[0036] Furthermore, such as Figure 1-3 As shown, it also includes a tension adjustment mechanism 3. The webbing 10 passes sequentially through the joint detection mechanism 1, the tension adjustment mechanism 3, and the calendering mechanism 2. In this embodiment, a tension detection mechanism (not shown in the figure) is set up to detect the tension value of the webbing 10. The tension detection mechanism feeds back the detection result to the control component. The control component controls the tension adjustment mechanism 3 to operate according to the detection result, thereby ensuring that the webbing 10 is always in a suitable tension state, thus ensuring the accuracy of the detection result of the joint detection mechanism 1 and ensuring the calendering effect of the calendering mechanism 2 on the webbing 10.

[0037] The above embodiments merely illustrate several implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
