Description

Technical Field

[0001] This utility model relates to the technical field of winding devices for printing and slitting equipment, and in particular to an automatic winding mechanism that does not require the machine to stop. Background Technology

[0002] In roll-type equipment such as slitting machines and gravure printing machines, the winding of finished roll materials usually relies on a take-up shaft or take-up drum. The traditional winding process generally includes: installing an empty take-up shaft on the winding device, starting the equipment to wind the material into a finished roll, stopping the machine to remove the take-up shaft after the roll reaches the set diameter or length, unloading the finished roll from the equipment, and then replacing it with a new take-up shaft to continue production.

[0003] The above process has significant shortcomings:

[0004] 1. Production interruption caused by machine stoppage and unloading: Rewinding and unloading must be completed sequentially on the same rewinding shaft, and the machine must be stopped before unloading. Frequent start-ups and shutdowns waste a lot of effective production time and reduce capacity.

[0005] 2. High manual labor intensity and many safety hazards: The winding shaft is large and heavy, and loading and unloading require manual positioning, clamping and handling, which is labor-intensive. If it is not fully reset before restarting the equipment, it is easy to cause the roll to loosen, shift or even damage the equipment.

[0006] 3. Difficulty in adapting to high-speed continuous production: With the market pace accelerating, the traditional model has become a bottleneck for capacity improvement, especially when multiple shifts are operating continuously, resulting in more significant losses.

[0007] 4. Limitations of existing improvement solutions: Although there are dual take-up shaft or spare shaft solutions, manual intervention is still required for switching, and full automation is not possible; moreover, the switching process lacks reliable synchronization with the start and stop of the equipment, which can easily lead to material waste and equipment risks, and cannot achieve truly non-stop automatic winding and unloading.

[0008] Therefore, there is an urgent need for a mechanism that can automatically switch the winding station and complete the unloading during continuous operation of the equipment, and has the functions of automatic clamping, winding and pressure roller pressing, so as to reduce downtime, reduce manual intervention and improve safety and production efficiency.

[0028] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] like Figure 1 — Figure 5As shown, this embodiment discloses an automatic winding mechanism that operates without stopping the machine. The specific structure is as follows: It includes two side plates 101, with a rotatable long rotating drum 102 and a short rotating drum 103 installed between the side plates. The long rotating drum 102 and the short rotating drum 103 are connected by a flipping seat 104. A flipping frame 105 is installed on the long rotating drum 102, and two winding stations 106 are provided on the flipping frame 105. The two winding stations 106 are symmetrically arranged with the long rotating drum 102 as the center. One side of the flipping frame 105 is integrally connected to the flipping seat 104. The two winding stations 106 are each driven by their respective first motors for winding, and the long rotating drum 102 is driven to rotate as a whole by a second motor.

[0030] The winding station 106 includes a fine-tuning and fixing part 109 and a pressing and driving part 110.

[0031] The clamping drive part 110 includes a second fixed sleeve 119 disposed on the flipping seat 104. A rotatable rotating sleeve 120 is connected to the second fixed sleeve 119 through a bearing. A drive shaft 121 is disposed inside the rotating sleeve 120. An axial concave-convex guide fit 122 is provided between the two. A guide sleeve 123 is connected to one side of the second fixed sleeve 119. A sliding plug 124 that slides along its inner hole is disposed inside the guide sleeve 123.

The clamping drive part 110 can press the take-up shaft against the fixed side positioning sleeve 116 for positioning and clamping, and at the same time drive the take-up shaft to rotate to complete the winding.

[0032] The inner wall of the short rotating drum 103 is connected to the transmission sleeve 128 via bearings. The inner wall of the transmission sleeve 128 is connected to the transmission shaft via bearings. Second pulleys 130 are respectively arranged on both sides of the transmission sleeve 128, and third pulleys 131 are respectively arranged on both sides of the transmission shaft. There are two first motors, each equipped with a fourth pulley. The fourth pulley of one first motor is connected to the second pulley 130 via a second belt. The second pulley 130 on the other side of the transmission sleeve 128 is connected to the corresponding first pulley via a belt. The fourth pulley of the other first motor is connected to the third pulley 131 on one side of the transmission shaft via a third belt. The third belt on the other side of the transmission shaft is connected to the other first pulley via a belt, so that the two winding stations 106 are driven independently by their respective first motors.

[0033] The second motor drives the long rotating cylinder 102 through a worm gear structure: a worm gear 135 is configured on the end shaft of the long rotating cylinder 102, and a rotatable worm gear 136 is installed on the side plate 101. The worm gear 136 meshes with the worm gear 135. A first sprocket is configured at the end of the worm gear 136, and a second sprocket is configured on the output shaft of the second motor. The first sprocket and the second sprocket are connected by a chain drive.

[0034] The flipping frame 105 is also equipped with shafts 140 corresponding to the winding stations 106. Two swing arms 141 are connected to the shafts 140, and pressure rollers 142 are installed at the ends of the two swing arms 141. A connecting plate 143 is fixed on the shafts 140, and a pressing cylinder 144 is installed corresponding to the connecting plate 143. The piston rod of the pressing cylinder 144 is connected to the connecting plate 143, which can drive the pressure rollers 142 to press against the finished roll material being wound, ensuring that the layers of the roll material are tight and preventing loosening. The positions of the two ends of the pressure rollers 142 are adjustable. The specific structure is as follows: One swing arm is provided with a transverse adjustment groove 145, and the other swing arm is provided with a longitudinal adjustment groove. One end shaft of the pressure roller 142 passes through the transverse adjustment groove and is connected to a transverse adjustment connecting rod 146. The other end shaft of the pressure roller passes through the longitudinal adjustment groove and is connected to a longitudinal adjustment connecting rod. The ends of the two swing arms are respectively provided with rotatable caps 147. The transverse adjustment connecting rod and the longitudinal adjustment connecting rod are respectively screwed to their respective caps. In this way, the two caps can adjust the position of the two ends of the pressure roller. After adjustment, the pressure roller can press against the surface of the coil material.

[0035] During operation, one winding station 106 is in the working position to wind up the material, and the pressure roller 142 presses down on the surface of the rolled material under the action of the pressing cylinder 144. When the rolled material reaches the set length, the second motor drives the long rotating drum 102 to rotate half a turn, and the other winding station 106 moves into the working position to continue winding up. At the same time, the original station moves to the unloading position to unload the material, so as to realize continuous production without stopping the machine.
