Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic parts processing technology, and in particular to an adjustable angle plastic parts surface spraying device. Background Technology
[0002] Plastic parts are widely used in various industrial and consumer products. Due to their lightweight, durability, and high plasticity, they have become an important part of the manufacturing industry. In order to improve the aesthetics and durability of plastic parts, surface spraying is an indispensable step. Through spraying, plastic parts can obtain a uniform coating, enhance their corrosion resistance and wear resistance, and improve their appearance. In order to ensure the quality of spraying and the precise control of the process, precise spraying equipment and supporting equipment are particularly important.
[0003] Existing plastic part spraying equipment typically has a non-adjustable spraying angle. When performing surface spraying operations on complex curved or arc-shaped plastic parts, it is easy to cause uneven coverage of the spraying area and incomplete spraying in some areas, which limits the applicability of the spraying equipment and makes it difficult to meet the diverse spraying needs of plastic parts. At the same time, when spraying individual plastic parts, existing spraying equipment lacks a convenient and efficient fixing structure. Most rely on manual positioning or simple slot fixing, which has poor fixing effect. During the spraying process, the plastic parts are prone to positional displacement due to airflow impact or equipment vibration, which adversely affects the final spraying effect.
[0004] Therefore, in view of the problems existing in the above-mentioned plastic parts spraying devices, this utility model places the plastic parts to be sprayed on the top of the placement platform, rotates the handle to drive the adjusting screw to rotate, drives the clamping block to move towards the plastic parts to be sprayed, and finally clamps them with the clamping pad to prevent shaking during the spraying process and improve the stability of the spraying operation. Rotating the handle drives the rotating rod and rotating disk to rotate, drives the rotating shaft to make circumferential motion, and through the connecting rod, causes the sliding block to make linear reciprocating motion along the guide rail, thereby driving the threaded rod to make linear reciprocating motion in the threaded sleeve, causing the threaded sleeve and the rotating semicircle to oscillate back and forth, thereby adjusting the angle of the spraying head, better covering the spraying needs of curved plastic parts, and improving the applicability of the spraying operation.

[0026] A fixing block 301 is fixedly connected to the top of the placement platform 3, and the fixing block 301 is located near the box 4. A clamping block 302 is slidably connected inside the placement platform 3, and the clamping block 302 is located away from the box 4. An adjusting screw 303 is rotatably connected inside the placement platform 3. The clamping block 302 is slidably connected to the outer wall of the adjusting screw 303.

[0027] The housing 4 is rotatably connected to a rotating disk 401. A rotating rod 5 is fixedly connected to the inner wall of the rotating disk 401. A rotating shaft 402 is fixedly connected to the side of the rotating disk 401 away from the rotating rod 5.

The sliding block 405 is slidably connected inside the guide rail 406. A push rod 407 is fixedly connected to the front of the sliding block 405. A threaded rod 408 is fixedly connected to the end of the push rod 407 away from the sliding block 405. The threaded rod 408 is threadedly connected inside the threaded sleeve 6.

[0030] A rotating semicircle 601 is fixedly connected to the outer wall of the threaded sleeve 6. The rotating semicircle 601 is rotatably connected to the front of the housing 4. A support 602 is fixedly connected to the side of the rotating semicircle 601 away from the housing 4. A spray head 603 is fixedly connected inside the support 602. The spray head 603 is located near the top of the placement platform 3. The rotating semicircle 601 swings synchronously with the threaded sleeve 6, thereby adjusting the angle of the spray head 603 on the support 602.
[0031] Working principle: According to Figures 1 to 4 When the device is ready for use, first, place the device in the work area. At this time, the support leg 2 provides stable support for the base 1. Then, place the plastic part to be sprayed on the top of the placement platform 3 and close to the fixing block 301. Hold the handle 304 and apply external force to rotate the handle 304, which drives the adjusting screw 303 to rotate, thereby driving the clamping block 302 to slide along the adjusting screw 303 in the placement platform 3 and gradually approach the plastic part to be sprayed. Finally, clamp the plastic part with the clamping pad 305 to prevent it from shaking during the spraying process, thus completing the preparation of the device.
[0032] according to Figures 1 to 2 When the device is put into use, firstly, the external spraying material is injected into the spray head 603, and the external spraying power source is connected to the spray head 603. The spray head 603 is fixed on the support 602 and spraying operation is performed on the plastic parts that are clamped on the placement platform 3. The support 602 ensures the stability of the spray head 603 during the spraying process.
[0033] according to Figures 2 to 5When it is necessary to adjust the spraying angle of the spray head 603, first, hold the handle 502 and apply external force to rotate the handle 502. The handle 502 drives the rotating rod 5 to rotate through the connecting rod 501, which in turn drives the rotating disk 401 to rotate inside the housing 4. This causes the rotating shaft 402 to move in a circular motion around the center of the rotating disk 401. During the circular motion, the rotating shaft 402 drives the connecting rod 403 to reciprocate within the housing 4. The connecting rod 403 drives the sliding block 405 to move in a straight line along the guide rail 406 through the connecting seat 404, thus converting the circular motion into linear motion.
[0034] according to Figures 2 to 5 During the rotation of handle 502, sliding block 405 drives threaded rod 408 to perform linear reciprocating motion via push rod 407. Threaded rod 408 continuously performs linear reciprocating motion within threaded sleeve 6, driving threaded sleeve 6 to swing inside housing 4, thereby driving rotating semicircle 601 to swing synchronously on the front of housing 4, thus realizing the angle adjustment of spray head 603 on support 602. The adjustment range is limited by the distance from rotating shaft 402 to the center of rotating disk 401.
[0035] The spray head 603 is a technology already available on the market and will not be described in detail here.
[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
