Description

Technical Field

[0001] The utility model belongs to the technical field of temperature control of cold rollers of coating machines, in particular to a novel precise temperature control device for cold rollers of coating machines. Background Art

[0002] The cold roller precision temperature control device of the coating machine is a system used to control the temperature of the cold roller during the coating process, ensuring that the temperature of the substrate is accurately controlled during the vacuum coating process, thereby improving the coating quality and efficiency.

[0003] The existing coating machine cold roller precision temperature control device usually uses water cooling to control the temperature of the cold roller. However, in this way, the water flows directly through the cold roller, which makes it difficult to accurately control the temperature of the cold roller. In addition, the direct flow method takes a long time to control the temperature of the cold roller, which is inefficient and still affects the quality of the coating process. Therefore, we propose a new type of coating machine cold roller precision temperature control device. Utility Model Content

[0004] The purpose of the present utility model is to provide a novel precision temperature control device for the cold roller of a coating machine, which solves the problem that the existing precision temperature control device for the cold roller of a coating machine usually uses water cooling to control the temperature of the cold roller, but the water flows directly through the cold roller in a flowing manner, making it difficult to accurately control the temperature of the cold roller, which will still affect the quality of the coating process.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A conical ring is fixedly connected to the inner wall of the drainage cavity, a control ring is slidably connected to the inner side of the conical ring, a plurality of drain grooves are opened inside the control ring, a sealing ring is sleeved on the outer side of the control ring, a connecting rod is fixedly connected to the inner wall of the control ring, and a limiting rod is fixedly connected to the right side of the control ring.

[0008] Furthermore, the outer side and inner wall of the cold roller are in contact with a limit ring, the inner side of the limit ring is fixedly connected to the outer surface of the inner roller, and a plurality of flow pipes are arranged inside the cold roller. The left and right sides of the flow pipes are fixedly connected to the surface of the inner roller, the left side of the flow pipe is interconnected with the interior of the drainage cavity, and the right side of the flow pipe is interconnected with the interior of the water inlet cavity.

[0010] Furthermore, an arc frame is fixedly connected to the left side of the connecting rod, an arc groove is opened inside the arc frame, and the outer surface of the push-pull shaft contacts the inner wall of the arc groove.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0025] See also Figure 1-5 As shown, the utility model is a novel precision temperature control device for a cold roller of a coating machine, comprising a cold roller 1, an inner roller 11 is provided at the central axis of the cold roller 1, support seats 111 are fixedly connected to the left and right sides of the outer surface of the inner roller 11, connecting pipes 112 are fixedly connected to the left and right sides of the inner roller 11, a water inlet chamber 12 is opened on the right side of the inner roller 11, and a drainage chamber 13 is opened on the left side of the inner roller 11;

[0026] A conical ring 131 is fixedly connected to the inner wall of the drainage chamber 13, and a control ring 132 is slidably connected to the inner side of the conical ring 131. A number of leakage grooves are opened inside the control ring 132, and a sealing ring 133 is sleeved on the outer side of the control ring 132. A connecting rod 134 is fixedly connected to the inner wall of the control ring 132, and a limiting rod 135 is fixedly connected to the right side of the control ring 132. By setting the control ring 132, specifically, the size of the leakage groove will be regulated when the control ring 132 moves. When the leakage groove increases, the water flow speed is faster, thereby reducing the stay in the flow pipe 113. At this time, the water flow will pass quickly, thereby reducing the cooling speed of the cold roller 1. The control ring 132 can be adjusted to a suitable position according to different needs to control the water flow, thereby achieving the function of precise temperature control and improving the quality of coating.

[0027] The outer side and inner wall of the cold roller 1 are in contact with a limit ring 114, and the inner side of the limit ring 114 is fixedly connected to the outer surface of the inner roller 11. Several flow pipes 113 are arranged inside the cold roller 1, and the left and right sides of the flow pipe 113 are fixedly connected to the surface of the inner roller 11. The left side of the flow pipe 113 is interconnected with the inside of the drainage chamber 13, and the right side of the flow pipe 113 is interconnected with the inside of the water inlet chamber 12. The water flow is transported from the connecting pipe 112 on the right to the water inlet chamber 12, and then the water flow is diverted through several flow pipes 113. During the diversion process, the water flow will flow into the drainage chamber 13, and at the same time take away the heat on the cold roller 1.

[0028] The left side of the support seat 111 is fixedly connected to a support block 14, the bottom of the support block 14 is fixedly connected to a motor 141, the top output end of the motor 141 is fixedly connected to a rotating shaft and extends to the inside of the drainage chamber 13, the outer surface of the rotating shaft is rotatably connected to the bottom of the inner roller 11, the top of the rotating shaft is fixedly connected to a rotating rod 142, the top of the rotating rod 142 is fixedly connected to a push-pull shaft 143, and when the rotating rod 142 rotates, it will drive the push-pull shaft 143 to rotate left or right, thereby smoothly driving the arc frame 341 to move.

[0029] An arc-shaped frame 341 is fixedly connected to the left side of the connecting rod 134, and an arc-shaped groove 342 is opened inside the arc-shaped frame 341. The outer surface of the push-pull shaft 143 contacts the inner wall of the arc-shaped groove 342. By setting the arc-shaped frame 341, specifically when the motor 141 drives the rotating rod 142 to rotate, the rotating rod 142 drives the arc-shaped frame 341 to move through the push-pull shaft 143. Since the arc-shaped frame 341 is arranged in an arc shape, the push-pull shaft 143 will smoothly drive the arc-shaped frame 341 to move left or right without affecting the rotation of the push-pull shaft 143, thereby satisfying the adjustment function of the control ring 132.

[0030] The right side of the limiting rod 135 passes through the inner roller 11 and extends to the inside. The limiting rod 135 is slidably connected to the inner roller 11. The left and right sides of the conical ring 131 are both conical settings. The left side of the inner wall of the water inlet chamber 12 is a conical surface setting. A sealing ring is fixedly connected to the outer surface of the rotating shaft. The top of the sealing ring contacts the bottom of the inner roller 11. The left side of the inner wall of the water inlet chamber 12 is a conical surface, which can play a role in diversion, so that the water flow can be smoothly diverted to several flow pipes 113.

[0031] A specific application of this embodiment is:

[0032] When in use, water is transported from the right connecting pipe 112 to the water inlet chamber 12, and then the water is diverted through several flow pipes 113. During the diversion process, the water flows into the drainage chamber 13, and at the same time takes away the heat on the cold roller 1. After the water enters the drainage chamber 13, it is discharged to the left side of the conical ring 131 through the leakage groove on the control ring 132, and then discharged from the left connecting pipe 112, so that the temperature of the cold roller 1 can be reduced. By starting the motor 141 and driving the rotating shaft The rotating rod 142 rotates slowly, and the rotating rod 142 drives the push-pull shaft 143 to move together. When the push-pull shaft 143 rotates to the left, the arc frame 341 is pulled to the left. When the push-pull shaft 143 moves to the right, the arc frame 341 is driven to move to the right. The arc groove 342 on the arc frame 341 is not at the same center as the rotating rod 142, so it will not affect the push-pull shaft 143 to drive the arc frame 341 to move. The arc frame 341 will drive the arc frame 341 through the connecting rod 134. When the control ring 132 moves to the left or right, the right side of the control ring 132 drives the limit rod 135 to slide in the inner roller 11, thereby improving the stability of the control ring 132. By moving the control ring 132, the size of the leakage groove on the control ring 132 can be adjusted. When the leakage groove is reduced, the water flow rate is slower, so that the water flow can stay in the flow pipe 113 for a longer time, thereby fully utilizing the water cooling to control the temperature. When the leakage groove is enlarged, the water flow rate is faster, thereby reducing the stay in the flow pipe 113. At this time, the water flow will pass through quickly, thereby reducing the cooling speed of the cold roller 1. The control ring 132 can be adjusted to a suitable position according to different needs to control the water flow, thereby achieving the function of precise temperature control and improving the quality of coating. When the temperature control of the cold roller 1 is not required, the control ring 132 is pulled to the left so that the sealing ring 133 contacts the inner wall of the tapered ring 131, so that the drainage chamber 13 can be sealed. At this time, the water flow will not be discharged, and the temperature control of the cold roller 1 can be stopped.
