Description

Technical Field

[0001] This utility model relates to the technical field of spray coating equipment for cup production, specifically an irregular color-changing spray coating mechanism for thermos cup production. Background Technology

[0002] The inner liner and outer shell of a thermos flask are usually made of metals such as stainless steel. Although metals themselves have a certain degree of corrosion resistance, the metal surface may oxidize and rust when the outer surface comes into contact with water or air humidity during long-term use, affecting safety and service life. The spraying mechanism evenly sprays an anti-corrosion coating on the surface of the thermos flask to form a dense protective film, which isolates the substrate from direct contact with the external environment, effectively resisting corrosion and wear, and extending the service life of the thermos flask.

[0003] The existing technology has the following problems: To meet diverse individual needs, many thermos cups with irregular shapes and temperature-sensitive color have emerged. However, in the production of thermos cups, irregular shapes can lead to uneven spraying of the outer surface by the spraying device. This causes the color-changing coating to accumulate or drip under irregular shapes, reducing the color-changing effect and spraying uniformity. Furthermore, the spraying device cannot automatically adapt to various irregular thermos cup outer surfaces, resulting in low applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an irregular color-changing spraying mechanism for the production of thermos cups, which solves the problem of uneven spraying.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an irregular color-changing spraying mechanism for the production of thermos cups includes a collar, a plurality of horizontal coating components are arranged on the inner side of the collar, a vertical coating component is arranged on the inner side of the horizontal coating components, and a plurality of slide rails are arranged on the outer side of the collar.

[0006] Preferably, the transverse coating component includes an electric push rod fixedly connected to the inner side of the collar, a connecting slide plate fixedly connected to the end of the electric push rod away from the collar, and positioning components slidably connected to both ends of the connecting slide plate. A rectangular support frame is fitted together on the upper and lower ends of the two positioning components away from the connecting slide plate, and a vertical roller is rotatably connected to the outer surface of the positioning component in the vertical direction.

[0007] Preferably, the positioning component includes connecting posts with both ends respectively sleeved on the upper and lower horizontal outer surfaces of the support frame, a support spring fixedly connected to the middle of the side of the connecting post away from the support frame, and a connecting plate fixedly connected to the end of the support spring away from the connecting post.

[0008] Preferably, the connecting plate and the connecting column are slidably connected to a telescopic column on opposite sides, and the upper and lower sides of the end of the connecting plate away from the telescopic column are fixedly connected to sliding columns, which are slidably connected inside the connecting slide plate.

[0009] Preferably, the vertical coating component includes a rectangular support frame two, with horizontal rollers rotatably connected to the outer surface of the support frame two in the horizontal direction. The support frame two and the horizontal rollers are located at the center of the support frame one, and a plurality of support and bonding components are movably connected to one end of the support frame two in the vertical direction near the connecting column.

[0010] Preferably, the support fitting assembly includes a second telescopic column, with connecting balls fixedly connected to both ends of the second telescopic column. The two connecting balls are movably connected to the connecting column and the inside of the second support frame, respectively. A fitting spring is sleeved on the outer surface of the second telescopic column, with both ends of the fitting spring fixedly connected to the opposite sides of the two connecting balls.

[0011] This invention provides a vertical application component and a horizontal application component. Compared with the prior art, it has the following advantages: 1. This irregular color-changing spraying mechanism for the production of thermos cups, through the cooperation of horizontal and vertical coating components, can apply the coating sprayed on the surface of the thermos cup through vertically opposing rollers in different operating states. It can effectively solve the problem of uneven spraying caused by irregular appearance, and avoid the accumulation or dripping of color-changing coating under irregular shape, thereby improving the color-changing effect and spraying uniformity of the coating.

[0012] 2. The irregular color-changing spraying mechanism for producing thermos cups, through the cooperation of the support and fitting components and the positioning components, enables the second support frame and the first support frame to change their angles within a certain range, so that the vertical roller and the horizontal roller can automatically adapt to various irregular shapes and fit onto the outer surface of the thermos cup, no longer limited by the appearance shape of the thermos cup, thus improving the applicability and adaptability of the spraying device.

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution: an irregular color-changing spraying mechanism for the production of thermos cups, including a collar 1, a plurality of horizontal coating components 4 are arranged inside the collar 1, a vertical coating component 2 is arranged inside the horizontal coating components 4, and a plurality of slide rails 3 are arranged outside the collar 1.

[0017] The collar 1 serves as the basic frame, and the slide rail 3 can be connected to an external moving device, allowing the entire spraying mechanism to move along the axis of the thermos cup. The horizontal coating component 4 and the inner vertical coating component 2 form a composite coating structure. When the thermos cup is placed in the center of the mechanism, the slide rail 3 drives the collar 1 to move. The horizontal and vertical coating components 2, in conjunction with the rotation of the thermos cup, perform coating operations on the outer surface of the thermos cup, ensuring the basic uniformity of the coating coverage.

[0018] Please see Figure 2 The horizontal coating component 4 includes an electric push rod 45 fixedly connected to the inside of the collar 1. The end of the electric push rod 45 away from the collar 1 is fixedly connected to a connecting slide plate 44. Both ends of the connecting slide plate 44 are slidably connected to positioning components 43. The upper and lower ends of the two positioning components 43 away from the connecting slide plate 44 are fitted with a rectangular support frame 42. The outer surface of the positioning components 43 in the vertical direction is rotatably connected to a vertical roller 41.

[0019] The electric push rod 45 drives the connecting slide plate 44 to move radially along the collar 1 via telescopic drive, causing the positioning components 43 on both sides to drive the support frame 42 and the vertical roller 41 to come close to the outer surface of the thermos cup. When encountering irregular curved surfaces, the positioning components 43 can slide along the connecting slide plate 44, so that the vertical roller 41 always fits the cup body. When the thermos cup rotates under the drive of the external structure, the vertical roller 41 rolls laterally, initially smoothing the sprayed coating and reducing the accumulation of paint in irregular areas.

[0020] Please see Figure 3 The positioning component 43 includes a connecting post 431 with both ends respectively sleeved on the upper and lower horizontal outer surfaces of the support frame 42. A support spring 432 is fixedly connected to the middle of the side of the connecting post 431 away from the support frame 42, and a connecting plate 434 is fixedly connected to the end of the support spring 432 away from the connecting post 431.

[0021] Please see Figure 3 The connecting plate 434 and the connecting column 431 are slidably connected to each other on opposite sides by a telescopic column 433. The upper and lower sides of the end of the connecting plate 434 away from the telescopic column 433 are fixedly connected to sliding columns 435, which are slidably connected inside the connecting slide plate 44.

[0022] When the vertical roller 41 contacts the uneven surface of the thermos, the support spring 432 is compressed and contracts or extends, pushing the connecting plate 434 to slide within the connecting slide plate 44 through the sliding column 435. This ensures that the positioning component 43 adaptively adjusts its position in the lateral direction, so that the vertical roller 41 maintains constant pressure with the surface of the cup, avoiding uneven application force caused by surface irregularities.

[0023] Please see Figure 4 The vertical coating component 2 includes a rectangular support frame 21. The horizontal outer surface of the support frame 21 is rotatably connected to a horizontal roller 23. The support frame 21 and the horizontal roller 23 are located at the center of the support frame 42. Several support bonding components 22 are movably connected to one end of the support frame 21 in the vertical direction near the connecting column 431.

[0024] The horizontal roller 23 rolls vertically along the thermos cup as the collar 1 moves. The connecting post 431 of the support and bonding component 22 connects the support frame 21 and the positioning component 43. When the horizontal coating component 4 adjusts with the undulation of the cup surface, the support and bonding component 22 drives the support frame 21 to move synchronously through elastic deformation, so that the horizontal roller 23 adheres to the cup body in the vertical direction, forming a crisscross coating path with the vertical roller 41, further improving the uniformity of the coating.

[0025] Please see Figure 5The support fitting component 22 includes a telescopic column 222, with connecting balls 221 fixedly connected to both ends of the telescopic column 222. The two connecting balls 221 are movably connected to the connecting column 431 and the support frame 21 respectively. A fitting spring 223 is sleeved on the outer surface of the telescopic column 222, with both ends of the fitting spring 223 fixedly connected to the opposite sides of the two connecting balls 221 respectively.

[0026] The connecting balls 221 at both ends of the telescopic column 222 move within the connecting column 431 and the support frame 21, respectively. When the surface of the thermos cup changes in curvature, the fitting spring 223 is compressed or extended, pushing the telescopic column 222 to extend or retract. At the same time, the connecting balls 221 allow the support frame 21 to rotate slightly in three dimensions, so that the horizontal roller 23 fits tightly against the irregular curved surface. Combined with the action of the horizontal coating component 4, the coating of the thermos cup with complex shape is finely smoothed, eliminating dripping or accumulation after spraying.

[0027] Please see Figures 1-5 At work, The thermos cup is placed in the center of the spraying mechanism. The collar 1 is connected to the external moving device through the outer slide rail 3 and positioned along the axial direction of the thermos cup. The electric push rod 45 is activated, causing it to extend and retract, driving the connecting slide plate 44 to move radially along the collar 1. This moves the positioning component 43 and the support frame 42 closer to the cup body, causing the vertical roller 41 to fit against the outer surface. When encountering an irregular curved surface, the support spring 432 of the positioning component 43 elastically deforms, pushing the connecting plate 434 to slide within the connecting slide plate 44 through the sliding column 435, thus allowing the vertical roller to... 41 Adaptive bonding and horizontal rolling smoothing of the coating. The support frame 21 of the vertical coating component 2 is connected to the connecting column 431 through the support bonding component 22. When the horizontal component is adjusted, the bonding spring 223 and the telescopic column 222 drive the horizontal roller 23 to roll along the vertical direction of the cup body, forming a longitudinal and transverse coating path with the vertical roller 41. The collar 1 moves along the slide rail 3, driving the horizontal and vertical rollers to work synchronously. Through the cooperation of the spring and the telescopic structure, the coating is continuously sprayed and smoothed on the irregular surface to ensure uniform coverage.
