Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating mechanism for a coating machine. Background Technology

[0002] Coating machines are mainly used for surface coating processes on films, paper, and other materials. This machine coats a roll of substrate with a specific functional adhesive, paint, or ink, and then dries it before cutting it into sheets or rewinding it. Existing automatic coating machines require operators to manually move the heavy coating rollers to a higher position on the machine for installation or removal from a higher position. Due to the weight of the coating rollers, installation and removal are very inconvenient, and there is a risk of them slipping during handling, posing a safety hazard. Therefore, we propose a coating mechanism for a coating machine. Utility Model Content

[0003] The purpose of this utility model is to provide a coating mechanism for a coating machine, which solves the problem of inconvenient replacement of coating rollers in the prior art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A coating mechanism of a coating machine, such as Figures 1-5 As shown, it includes a machine body 1; the machine body 1 is equipped with a pick-and-place roller mechanism 2, which can perform loading and unloading operations on the coating roller used for coating, thereby reducing the workload of the operator.

[0027] Specifically, the pick-and-place roller mechanism 2 includes a support plate 201, which supports the coating roller for subsequent coating operations. A support groove 202 is provided on the side of the support plate 201. The support groove 202 is semi-circular and can accommodate both ends of the coating roller. The rotating support plate 201 drives the coating roller to move along an arc-shaped trajectory around the outside of the support plate 201, thus enabling the upper and lower roller operations. A limit plate 203 is fixedly connected to the top of the inner wall of the machine body 1, and a limit frame 204 is fixedly connected to the inner wall of the machine body 1. The limit frame 204 limits the movement of the coating roller, ensuring that the movement of the coating roller is arc-shaped and revolves around the center of the support plate 201, preventing the coating roller from detaching from the support plate 201 when driven by it. The top of the limiting frame 204 is rotatably connected to a guide plate 205. The end of the guide plate 205 corresponds to the position of the limiting plate 203. The structure of the guide plate 205 can cooperate with the limiting plate 203. When the coating roller rotates upward and passes the guide plate 205, the guide plate 205 can be driven to rotate upward and open. When the coating roller moves in the opposite direction, the guide plate 205 is restricted by the limiting plate 203 and pushes the coating roller out from the inside of the support groove 202, realizing the automatic roller removal operation of the coating roller.

[0028] It is worth noting that a guide frame 206 is connected to the end of the guide plate 205. A guide groove 207 is formed on the inner side of the guide frame 206. The guide groove 207 guides the coating roller on the guide plate 205, allowing the coating roller to slide along the guide groove 207. The guide groove 207 has an arc-shaped structure, which slows down the movement of the coating roller and prevents damage caused by excessive speed. A collection box 208 is fixedly connected to the bottom of the guide frame 206. The collection box 208 is located at the end of the guide groove 207 and can collect the disassembled coating roller.

[0029] Based on this, a storage rack 209 is fixedly connected to the bottom of the machine body 1. The structure of the storage rack 209 can temporarily store the coating roller to be used. A feeding plate 210 is fixedly connected to the side of the storage rack 209. A screw 211 is meshed on the feeding plate 210. The screw 211 is rotatably connected to the storage rack 209. The structure of the feeding plate 210 can cooperate with the screw 211. Driven by the screw 211, the feeding plate 210 can push the coating roller to move, thereby feeding the coating roller onto the support plate 201. A motor is fixedly connected to one side of the bottom of the storage rack 209. The end of the motor output shaft is connected to the screw 211 through a bevel gear.

[0030] It is worth noting that a drive column 212 is rotatably connected to the side of the machine body 1. The drive column 212 can drive the support plate 201 and the coating roller carried on the support plate 201, allowing the support plate 201 to rotate. A drive handle 213 is connected to the drive column 212, which allows the operator to easily drive the drive column 212 to rotate. A meshing transmission gear 214 is fixedly connected to the outer side of the drive column 212 and the outer side of the support plate 201. The transmission gear 214 transmits the rotation of the drive column 212 to the support plate 201. The transmission gear 214 consists of two gears of different sizes; the smaller gear converts the operator's small torque into the larger gear's large torque, thereby manually driving the support plate 201 and the coating roller to rotate.

[0031] Example 2

[0032] like Figure 1 , Figure 3 , Figure 5 As shown, based on Embodiment 1, the machine body 1 is provided with a temporary storage mechanism 3. The temporary storage mechanism 3 can temporarily store the coating rollers that have been switched off, so that the coating rollers can be used alternately during the coating process, avoiding the operator from repeatedly changing the coating rollers.

[0033] In this embodiment, the temporary storage mechanism 3 includes a temporary storage rack 301, which is rotatably connected to both ends of the frame. The rotatably connected temporary storage rack 301 can provide temporary storage space for the coating roller, thereby facilitating the temporary storage of the coating roller. A temporary storage groove 302 is provided on the inner side of the temporary storage rack 301. The structure of the temporary storage groove 302 can accommodate the coating roller, facilitating the temporary storage operation of the coating roller. At the same time, the structure of the temporary storage groove 302 is interconnected with the gap between the limiting frame 204 and the support plate 201, thereby facilitating the movement of the coating roller from inside the support groove 202 onto the temporary storage rack 301. A support frame 303 is fixedly connected to one side of the temporary storage rack 301, and a drive rod 304 is connected to the other side of the temporary storage tank 302. The support frame 303 can support the temporary storage rack 301, allowing the temporary storage rack 301 to rotate around the support frame 303. At the same time, the drive rod 304 facilitates the operation of the operator. In addition, the distance between the drive rod 304 and the support frame 303 is 4-5 times the length of the temporary storage tank 302, so that the drive rod 304 forms a force-saving lever, making it convenient for the operator to rotate the temporary storage rack 301 containing the coating roller.

[0034] In addition, the support frame 303 has a "T"-shaped structure, and the moving groove structure facilitates the movement of the coating roller inside the receiving groove. The end of the temporary storage frame 301 has an arc-shaped structure, which allows the temporary storage frame 301 to maintain its correspondence with the limiting frame 204 during rotation.

[0035] Furthermore, a buffer plate 305 is slidably connected inside the temporary storage slot 302, and a buffer spring 306 is fixedly connected between the buffer plate 305 and the temporary storage rack 301.

[0036] In use, when the coating mechanism of the coating machine of this utility model needs to install the coating roller, the drive handle 213 first rotates the drive column 212, which drives the support plate 201 to rotate through the transmission gear 214, so that a support groove 202 on the outer side of the support plate 201 rotates to correspond with the position of the storage rack 209. Then the screw 211 rotates and pushes the feeding plate 210 and the coating roller upward until the coating roller moves into the support groove 202. Then the support plate 201 continues to rotate, so that the coating roller rotates to the top of the support plate 201. During the rotation of the coating roller with the support plate 201, when the coating roller moves past the guide plate 205, the coating roller pushes the guide plate 205 upward, so that the guide plate 205 rotates upward; and when the coating roller moves away from the guide plate 205, the guide plate 205 rotates in the opposite direction under the action of gravity until it is blocked by the limiting plate 203 and stops. At this time, the guide plate 205 is tilted towards the guide frame 206. When the coating roller needs to be removed, simply rotate the support plate 201 in the opposite direction. When the coating roller moves onto the guide plate 205, it is pushed out of the rotating support groove 202 by the limit plate 203, and the coating roller rolls along the tilted guide plate 205 into the guide frame 206. The coating roller then slides along the guide groove 207 on the inner side of the guide frame 206 into the collection box 208, which facilitates the subsequent collection of the replaced coating roller. When different coatings need to be applied to the film, the coating rollers at the top and bottom of the support plate 201 can be rotated to the temporary storage rack 301, and the temporary storage rack 301 can be rotated so that the temporary storage groove 302 corresponds to the coating roller, thus facilitating the temporary storage of the coating roller inside the temporary storage rack 301. The temporary storage rack 301 has two sets, allowing the two sets of coating rollers to be used alternately to meet the coating needs of different coatings. At the same time, the drive rod 304 structure can also serve as a guide rod to guide the film material and prevent the film from contacting the coating rollers inside the temporary storage rack 301 during movement.
