Technical Field
[0001] The utility model relates to the technical field of sprayers, and more particularly, to a linear module structure for a sprayer. Background Art
[0002] A release agent sprayer matched with a die casting machine is a key auxiliary device for realizing high-efficiency die casting production, and is specially designed for metal die casting processes such as aluminum alloy and zinc alloy. Through a precise control system, the spray track, pressure and dosage can be preset according to the structure of the mold cavity, and the release agent is uniformly atomized and then covers the surface of the mold to form a dense protective film, which prevents the casting from sticking to the mold and being scratched, and ensures the integrity of the product. Compared with manual spraying, it can reduce the consumption of release agent, improve operation efficiency, and at the same time reduce mold wear and the risk of manual exposure to chemicals, and is a core device in automated die casting production lines to guarantee molding quality and stabilize production rhythm.
[0003] Large sprayers for die castings are usually provided with a Y-axis, a Z-axis and a spraying mechanism. The Y-axis is a linear module used to drive the spraying mechanism to move linearly. At present, the linear modules of sprayers are divided into multi-stage drive structures. To meet the motion requirements of different stroke sections, each motion unit usually needs to be equipped with an independent drive motor, which increases the difficulty of cooperative control between each drive unit, and it is easy to cause deviation of the spray track due to synchronization deviation, which affects the spraying accuracy of the release agent. In view of this, we propose a linear module structure for a sprayer. Contents of Utility Model

Corresponding sliding rails are provided on the lower ends of the first-stage slide A, the first-stage slide B, the second-stage slide A and the second-stage slide B, and the side ends of the third-stage slide A and the third-stage slide B.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

When the first-stage slide A and B move under the drive of the first motor, the chain will drive the second-stage slide A and B to move synchronously.

Secondly, this design allows the second-stage stroke to be naturally linked with the first-stage stroke through the mechanical structure, avoiding the synchronization deviation that may be caused by multiple independent drives, greatly reducing the difficulty of coordinated control between drive units, ensuring the accuracy of the spray trajectory, and improving the quality of mold release agent spraying.

By adjusting the position of the nut on the adjusting rod, the tension of the chain can be easily adjusted to ensure the stability of the transmission. At the same time, this adjustable structure is also convenient for installation, debugging, and subsequent maintenance and parts replacement, reducing maintenance costs and difficulties.

Detailed Implementation
[0015] like Figures 1 to 7 As shown, this utility model relates to a linear module structure for a sprayer, including a mounting plate 101, a primary stroke mechanism 200 mounted on the mounting plate 101, a secondary stroke mechanism 300 mounted on the primary stroke mechanism 200, and a tertiary stroke mechanism 400 mounted on the primary stroke mechanism 200. A housing 102 is mounted on the mounting plate 101. The primary stroke mechanism 200 includes a primary slide A201 and a primary slide B202 slidably mounted on the mounting plate 101. The primary slide A201 and the primary slide B202 are interconnected. A first sprocket 204 and a second sprocket 205 are rotatably mounted on the side end of the primary slide B202. Both the first sprocket 204 and the second sprocket 205 are equipped with chains 206. The upper end of the mounting plate 101 is provided with two second connecting members 208, which are respectively connected to one end of the two chains 206. The secondary stroke mechanism 300 includes secondary slides A301 and B302 slidably mounted on primary slides A201 and B202. Two connecting plates 306 are provided on the side end of the secondary slide A301. First connecting members 207 are installed at the lower end of the connecting plates 306, and the two first connecting members 207 are respectively connected to the other end of the two chains 206. This invention enables the secondary stroke to be mechanically linked with the primary stroke, eliminating the need for an additional drive unit, reducing drive units, lowering energy consumption and simplifying collaborative control, avoiding synchronization deviations, ensuring accurate spray trajectory, and allowing the connecting members to adjust the tension of the chains 206 for easy maintenance.
[0016] Specifically, a first motor 103 is mounted on the side of the mounting plate 101, and a first gear 104 is mounted on the end of the output shaft of the first motor 103. A first gear plate 203 is mounted on the side of the first stage slide A201, and the first gear 104 meshes with the teeth on the first gear plate 203. The operation of the first motor 103 can rotate the first gear 104, and under the action of the first gear plate 203, the first stage slide A201 and the first stage slide B202 can move linearly.
[0017] Furthermore, the three-stage travel mechanism 400 includes a third-stage slide A401 and a third-stage slide B402 that are slidably mounted on the sides of the second-stage slide A301 and the second-stage slide B302, respectively. Limit rails 105 are provided on the upper ends of the mounting plate 101, the first-stage slide A201, and the first-stage slide B202, as well as on the sides of the second-stage slide A301 and the second-stage slide B302. Corresponding sliding rails are provided on the lower ends of the first-stage slide A201, the first-stage slide B202, the second-stage slide A301, and the second-stage slide B302, as well as on the sides of the third-stage slide A401 and the third-stage slide B402. The cooperation between the limit rail 105 and the sliding rail can limit the slide table in each stroke, ensuring its stability during linear motion. Secondly, each stroke is equipped with two slide table structures, which increases the contact area and connection points of the mechanism's limit and support. During operation, the load can be better distributed, reducing the pressure on a single cross seat, thereby improving the stability of the mechanism. This allows it to maintain smooth operation even when bearing a large weight, and it is not easy for it to shake or deviate.
[0018] It is worth noting that the upper ends of the secondary slides A301 and B302 are provided with a first connecting plate 305 connecting the secondary slides A301 and B302, and the upper ends of the tertiary slides A401 and B402 are provided with a second connecting plate 403 connecting the tertiary slides A401 and B402. A fixing plate 303 is provided at the rear of the upper ends of the secondary slides A301, B302, A401 and B402. The first linkage plate 305 connects the secondary slide A301 and the secondary slide B302. When the secondary slide A301 is driven to move, the secondary slide B302 will also move accordingly. The second linkage plate 403 connects the tertiary slide A401 and the tertiary slide B402. When the tertiary slide A401 is driven to move, the tertiary slide B402 will also move accordingly.
[0019] It is worth mentioning that a second motor 304 is installed at the upper end of the secondary slides A301 and B302, and a second gear is installed at the end of the output shaft of the second motor 304. A second gear plate 404 is installed at the upper end of the tertiary slide A401, and the second gear meshes with the teeth on the second gear plate 404. The operation of the second motor 304 can rotate the second gear, and under the action of the second gear plate 404, the tertiary slides A401 and B402 can move linearly.
[0020] It is worth noting that both the first connector 207 and the second connector 208 include symmetrically distributed limiting plates 209. A fixing groove 2091 is provided on the mating surface of the limiting plate 209. An adjusting rod 210 is provided in the fixing groove 2091. A limiting sleeve 211 is provided on the adjusting rod 210. The shape of the limiting sleeve 211 is adapted to the shape of the fixing groove 2091. A nut 212 is threaded on the adjusting rod 210. A connector 213 is provided at the end of the adjusting rod 210. The connector 213 is connected to the chain 206. When the primary slides A201 and B202 move linearly, the chain 206 applies tension to the first connector 207 and the second connector 208. Since the second connector 208 is fixed, the movement of the primary slides A201 and B202 compensates for the distance between the chain 206 and the second connector 208. Therefore, the chain 206 pulls the first connector 207, causing the secondary slides A301 and B302 to move. By using the chain 206 in conjunction with the first connector 207 and the second connector 208, the secondary slides A301 and B302 can move synchronously, reducing the number of drive units. The first connector 207 effectively reduces equipment energy consumption and maintains a relatively accurate transmission ratio, thereby reducing the difficulty of coordinated control between various drive units and avoiding synchronization deviation problems that may occur due to multiple independent drives. Secondly, the adjusting rod 210 of the first connector 207 and the second connector 208 can be adjusted in length and disassembled. This allows the tension of the chain 206 to be adjusted according to actual needs during installation and debugging, ensuring the stability of the transmission. At the same time, the easy disassembly of the adjusting rod 210 facilitates the overall disassembly of the chain 206 structure, which also provides convenience for subsequent maintenance and replacement of parts, reducing maintenance costs and difficulties.
[0021] Working Principle: This embodiment provides a linear module structure for a sprayer. During use, the first motor 103 on the side of the mounting plate 101 starts working, and its output shaft drives the first gear 104 to rotate. Since the first gear 104 meshes with the first toothed plate 203 on the side of the first-stage slide A201, the rotation of the first gear 104 is converted into linear motion of the first-stage slide A201. The first-stage slide A201 and the first-stage slide B202 are interconnected, so they slide synchronously along the limiting rail 105 on the upper end of the mounting plate 101, realizing the extension or contraction of the first-stage stroke. Simultaneously with the movement of the first-stage stroke mechanism 200, the second-stage stroke mechanism 300 moves in tandem, and the first sprocket 20 on the side of the first-stage slide B202... 4. The second sprocket 205 moves synchronously with the first-stage slide B202. The two second connecting pieces 208 at the upper end of the mounting plate 101 are fixed in position and respectively connected to one end of the chain 206 on the first sprocket 204 and the second sprocket 205. When the first-stage slides A201 and B202 move, the chain 206 is pulled. Since the other end of the chain 206 is connected to the connecting plate 306 on the side of the second-stage slide A301 via the first connecting piece 207, the tension of the chain 206 will drive the second-stage slide A301 to move. Because the second-stage slides A301 and B302 are connected via the first connecting plate 305, the second-stage slides A301 and B302 will move along the first-stage slide A202. The first-stage slide B202 slides synchronously with the limiting rail 105 at the upper end to achieve the second-stage stroke movement. During this process, the adjusting rod 210 in the first connecting piece 207 and the second connecting piece 208 can be adjusted in length according to the actual situation and fixed by the nut 212 to ensure that the tension of the chain 206 is appropriate and to ensure stable transmission. When it is necessary to drive the third-stage stroke mechanism 400 to move, the second motor 304 at the upper end of the second-stage slide A301 and the second-stage slide B302 works, and the second gear at the end of its output shaft rotates. Because the second gear meshes with the second gear plate 404 at the upper end of the third-stage slide A401, the rotation of the second gear will drive the third-stage slide A401 to move linearly. The third-stage slide A401 and the third-stage slide B402 is connected via the second linkage plate 403, so the two slide synchronously along the limiting rails 105 on the sides of the secondary slides A301 and B302 to achieve three-stage stroke movement. During the entire movement, the limiting rails 105 on the mounting plate 101, the primary slide A201, the primary slide B202, and other components cooperate with the corresponding sliding rails to limit and guide the movement of each slide, ensuring that each stage of the stroke mechanism can maintain stable linear movement. At the same time, the fixing plates 303 on the secondary slides A301, B302, A401, and B402 are used to install spray-related components, and achieve precise adjustment of the spray position with the movement of each stage of the stroke mechanism.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
