Technical Field

[0001] This application relates to the field of roll material correction technology, specifically to a roll material correction device for printing and slitting. Background Technology

[0002] During the production process of roll materials, especially in the printing and slitting stages, lateral deviation often occurs due to various reasons, leading to unstable roll material feeding and affecting production efficiency and quality. Traditional correction methods rely on mechanical devices to correct the deviation, but these methods are often only applicable to a single feeding direction and are prone to causing damage to the roll material or equipment during processing. Therefore, there is an urgent need for a new correction device that can adaptively correct deviations in different roll material feeding directions while minimizing damage to the roll material.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] like Figures 1 to 5 As shown, a roll material correction device for printing and slitting includes a base 101. A right side support frame 102 is fixedly mounted on the base 101. A right outer support rod 103 is rotatably mounted on the side support frame 102. An inner support rod 104 is fixedly mounted on the outer support rod 103. An inner rotating shaft 106 is fixedly mounted on the inner support rod 104. A V-shaped support rod 107 is rotatably mounted on the inner rotating shaft 106. The V-shaped support rod 107 has a V-shaped structure. Two rotating shafts 108 are rotatably mounted on the V-shaped opening of the V-shaped support rod 107. A right contact wheel 109 and a left contact wheel 110 are respectively mounted on the two rotating shafts 108. Both the right contact wheel 109 and the left contact wheel 110 are provided with threaded strips, and their installation directions are opposite.

[0023] Specifically, when the roll material is conveyed on the roller 116, it is detected by a laser sensor. When a deviation occurs, one of the two rotating shafts 108 is controlled to approach and contact the roll material conveyed on the roller 116 according to the direction of the deviation. The threaded belt of the right contact wheel 109 or the left contact wheel 110 on the rotating shaft 108 drives the roll material to move laterally on the roller 116, that is, to correct the previous deviation. The reverse-arranged threaded belts on the right contact wheel 109 and the left contact wheel 110 realize the bidirectional movement of the roll material to adapt to the deviation correction of the roll material.

[0024] When the roll material is not misaligned during use, the two rotating shafts 108 on the V-shaped support rod 107 are driven to rotate in the same direction by the power transmission mechanism, and the V-shaped support rod 107 remains stationary on the inner rotating shaft 106. When misalignment occurs, the switching mechanism controls the V-shaped support rod 107 to rotate a certain angle on the inner rotating shaft 106, so that one of the two rotating shafts 108 on the V-shaped opening of the V-shaped support rod 107 is close to the roller 116, and the other rotating shaft 108 is away from the roller 116. The rotating shaft 108 close to the roller 116 contacts the roll material. By rotating the rotating shaft 108, the threaded belt drives the roll material to be conveyed and moves laterally on the roller 116, thereby correcting the misalignment. After returning to the original position, the switching mechanism is controlled to reset, so that the V-shaped support rod 107 is reset under the action of the torsion spring 105.

[0025] like Figure 1 and Figure 2 As shown, a bidirectional motor 113 is fixedly mounted on the base 101. A drive shaft 112 is fixedly connected to the output end of the bidirectional motor 113. A lower gear 114 is fixedly mounted on the drive shaft 112. A roller 116 is rotatably mounted on the base 101. An upper gear 115 is fixedly mounted on the roller 116. The upper gear 115 meshes with the lower gear 114.

[0026] like Figure 2 and Figure 3 As shown, a connecting shaft 111 is rotatably mounted on the side support frame 102. The connecting shaft 111 is rotatably mounted on the inner rotating shaft 106. Multiple belts are mounted on the connecting shaft 111. One end of the connecting shaft 111 near the V-shaped support rod 107 is connected to two rotating shafts 108 via belts, and the other end of the connecting shaft 111 away from the V-shaped support rod 107 is connected to the drive shaft 112 via belts.

[0027] Specifically, the power transmission mechanism includes a bidirectional motor 113, a drive shaft 112, a lower gear 114, and a connecting shaft 111. In use, the bidirectional motor 113 drives the drive shaft 112 to rotate, the drive shaft 112 drives the lower gear 114 to rotate, and the lower gear 114 drives the upper gear 115 and the roller 116 to rotate on the base 101 through meshing with the upper gear 115. The drive shaft 112 also drives the connecting shaft 111 to rotate on the side support frame 102 via a belt. The connecting shaft 111 then drives two rotating shafts 108 to rotate on the V-shaped support rod 107 via two belts, thereby causing the two rotating shafts 108 and the roller 116 to rotate in opposite directions. The two rotating shafts 108 are located on both sides of the roller 116, so that regardless of whether the conveying direction of the roll material changes, the output and correction of the roll material can be achieved by controlling the rotating shafts 108 on both sides to approach the roll material. This avoids the limitation of the equipment that can only set the roll material to be conveyed in one direction, thereby improving the application range and applicability of the equipment. This correction device can be set up in any conveying direction of the roll material.

[0028] like Figure 3 As shown, a support frame 119 is fixedly installed on the side support frame 102, and an arc-shaped frame 120 is fixedly installed on the support frame 119. Two rotating shafts 108 are slidably installed on the arc-shaped groove of the arc-shaped frame 120.

[0029] Specifically, both pivots 108 of the V-shaped support rod 107 slide on the arc-shaped groove of the arc-shaped frame 120. The arc-shaped groove restricts the movement of the pivots 108 and prevents them from shaking when rotating. When the pivot 108 is pushed, it slides on the arc-shaped groove of the arc-shaped frame 120, and the V-shaped support rod 107 drives the other pivot 108 to slide synchronously.

[0030] like Figure 1 As shown, a torsion spring 105 is fixedly installed on the inner support rod 104. The torsion spring 105 is sleeved on the inner rotating shaft 106 and is also fixedly connected to the V-shaped support rod 107.

[0031] Specifically, when the rotating shaft 108 pushes the V-shaped support rod 107 to rotate on the inner rotating shaft 106, the V-shaped support rod 107 twists the torsion spring 105 on the inner support rod 104, so that when the rotating shaft 108 loses thrust, the V-shaped support rod 107 and the rotating shaft 108 are reset by the elastic force of the torsion spring 105.

[0032] like Figure 4 and Figure 5 As shown, an electric cylinder 117 is fixedly installed on the side support frame 102, and a push rod 118 is fixedly installed at the output end of the electric cylinder 117. The end of the push rod 118 near the base 101 is slidably connected to the base 101. A buffer wheel 121 is rotatably installed on the rotating shaft 108. The diameter of the buffer wheel 121 is larger than the diameter of the arc frame 120.

[0033] Specifically, such as Figure 2 and Figure 3As shown, when it is necessary to control the rotating shaft 108 to slide on the arc frame 120, the switching mechanism is activated. The switching mechanism includes an electric cylinder 117, a push rod 118, and a buffer wheel 121. Based on the offset direction, it selects which rotating shaft 108 to control to approach the roller 116. Then, the electric cylinder 117 is activated. The electric cylinder 117 controls the push rod 118 to slide left and right on the base 101, thereby selectively pushing the rotating shaft 108 so that the rotating shaft 108 on one side approaches the roller 116. That is, the push rod 118 pushes the buffer wheel 121 on the rotating shaft 108. The flexible material set on the buffer wheel 121 buffers the force generated when the push rod 118 pushes, avoiding direct contact with the rotating shaft 108 and thus avoiding the sparks generated by metal friction from affecting the safety of the roll material. The push rod 118 has a vertical rod on the outside of the buffer wheel 121 of the two rotating shafts 108. When the push rod 118 moves, the two vertical rods not only push the corresponding buffer wheel 121 to move, but also limit and buffer the other buffer wheel 121. This prevents the buffer wheel 121 and the rotating shaft 108 from pushing the V-shaped support rod 107 to rotate too much on the inner rotating shaft 106 due to the thrust. That is, the large angle of rotation due to inertia will cause the right contact wheel 109 or the left contact wheel 110 on the rotating shaft 108 to have excessive contact with the roll material and damage the roll material.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
