Description

Technical Field

[0001] This utility model relates to the technical field of small sheet metal parts spraying equipment, specifically, to a reciprocating spraying machine for spraying small sheet metal parts. Background Technology

[0002] In the processing of small sheet metal parts, spraying is an essential step. Traditional spraying methods, such as manual spraying, have many problems. On the one hand, manual spraying is difficult to guarantee the uniformity of the spraying, which can easily lead to some areas of the sheet metal part being sprayed too thickly or too thinly, affecting the appearance and quality of the product. Therefore, reciprocating spraying machines are needed to spray small sheet metal parts.

[0003] However, existing technologies still have many shortcomings in practical use. For example, existing reciprocating sprayers can only spray small sheet metal parts in one direction and cannot spray small sheet metal parts simultaneously in two directions. Reciprocating spraying in one direction leads to uneven spraying of small sheet metal parts, resulting in some areas of small sheet metal parts being sprayed too thick or too thin, affecting the appearance and quality of small sheet metal parts. Utility Model Content

[0004] The purpose of this utility model is to provide a reciprocating spraying machine for spraying small sheet metal parts, which solves the problem in the prior art that can spray small sheet metal parts simultaneously in two directions, but the reciprocating spraying in one direction leads to uneven spraying of small sheet metal parts, resulting in some areas of small sheet metal parts being sprayed too thick or too thin.

[0005] This utility model provides the following technical solution: a reciprocating spraying machine for spraying small sheet metal parts, including a mounting frame, a first reciprocating mechanism for horizontal spraying of small sheet metal parts is provided on the inner side of the mounting frame, a second reciprocating mechanism for vertical spraying of small sheet metal parts is provided on the inner side of the first reciprocating mechanism, and a spraying mechanism for spraying coating on small sheet metal parts is provided at the bottom end of the second reciprocating mechanism.

[0006] As a preferred embodiment of the above technical solution, the first reciprocating mechanism includes a reciprocating lead screw and a servo motor. The two ends of the reciprocating lead screw are rotatably mounted on the inner side of the mounting frame. A limit rod is fixedly mounted on the side of the mounting frame near the reciprocating lead screw. The servo motor is mounted on one side of the outer wall of the mounting frame via a mounting plate. The output end of the servo motor is fixedly connected to one end of the reciprocating lead screw via a shaft.

[0007] The above technical solution involves starting a servo motor to drive the reciprocating lead screw mounting bracket to rotate, which in turn allows the rotating reciprocating lead screw to drive the lead sleeve seat to reciprocate on the surfaces of the reciprocating lead screw and the limit rod.

[0008] As a preferred embodiment of the above technical solution, a threaded sleeve seat is slidably fitted on the surface of the reciprocating lead screw and the limiting rod, and a sliding groove is provided at the bottom end of the threaded sleeve seat, with a slider slidably installed inside the sliding groove.

[0009] Through the above technical solution, the reciprocating threaded sleeve seat drives the spray head to move laterally back and forth, which facilitates the spray head to perform lateral reciprocating spraying on small sheet metal parts.

[0010] As a preferred embodiment of the above technical solution, the second reciprocating mechanism includes a drive motor, the bottom end of which is fixedly installed on one side of the top of the wire sleeve seat. The output end of the drive motor is fixedly connected to a rotating rod via a shaft. The bottom end of the rotating rod extends through the interior of the wire sleeve seat to the bottom end of the wire sleeve seat. A crank is fixedly fitted onto the surface of the rotating rod away from the drive motor.

[0011] With the above technical solution, the start-up drive motor drives the crank to rotate at the bottom of the thread sleeve seat through the shaft, and the rotating rod drives the crank to rotate.

[0012] As a preferred embodiment of the above technical solution, the end of the crank away from the rotating rod is connected to a connecting rod via a shaft, and the top end of the connecting rod away from the crank is connected to a connecting vertical rod via a shaft. The top end of the connecting vertical rod is fixedly connected to one side of the bottom end of the slider.

[0013] The above technical solution uses a rotating crank to drive a connecting rod to rotate, which in turn drives a slider to reciprocate within a groove via a connecting vertical rod.

[0014] As a preferred embodiment of the above technical solution, the spraying mechanism includes a connecting plate, the bottom end of which is fixedly connected to the other side of the bottom end of the slider, and a mounting base is fixedly connected to the bottom end of the connecting plate.

[0015] Through the above technical solution, the reciprocating slider drives the spray head to move longitudinally back and forth through the connecting plate and the mounting base, which facilitates the spray head to perform longitudinal reciprocating spraying on small sheet metal parts.

[0016] As a preferred embodiment of the above technical solution, a storage tank is fixedly installed at the top of the mounting base, and the output end of the storage tank extends through the interior of the mounting base to the bottom end of the mounting base via a pipe. A spray head is connected to the bottom end of the storage tank via a pipe.

[0017] The above technical solution involves storing paint for spraying small sheet metal parts in a storage tank, and then spraying the paint stored in the storage tank evenly onto the surface of the small sheet metal parts by opening the spray head, thereby achieving the purpose of spraying the small sheet metal parts.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention enables the spraying mechanism to move laterally by activating a first reciprocating mechanism and longitudinally by activating a second reciprocating mechanism. The cooperation of the first and second reciprocating mechanisms allows the spraying mechanism to perform all-around spraying on small sheet metal parts, achieving simultaneous spraying in two directions. This solves the problem of uneven spraying of small sheet metal parts caused by reciprocating spraying in one direction, resulting in some areas of the small sheet metal parts being sprayed too thickly or too thinly, thus ensuring the appearance and quality of the small sheet metal parts.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1-4As shown, this utility model provides a technical solution: a reciprocating spraying machine for spraying small sheet metal parts, including a mounting frame 1. A first reciprocating mechanism 2 for horizontal spraying of small sheet metal parts is provided on the inner side of the mounting frame 1. The first reciprocating mechanism 2 includes a reciprocating lead screw 201 and a servo motor 203. Both ends of the reciprocating lead screw 201 are rotatably mounted on the inner side of the mounting frame 1. A limit rod 202 is fixedly mounted on the side of the mounting frame 1 near the reciprocating lead screw 201. The servo motor 203 is mounted on one side of the outer wall of the mounting frame 1 via a mounting plate. The output end of the servo motor 203 is connected to one end of the reciprocating lead screw 201 via a shaft. A fixed connection is established, and a threaded sleeve seat 204 is slidably fitted onto the surface of the reciprocating lead screw 201 and the limiting rod 202. A groove 205 is provided at the bottom end of the threaded sleeve seat 204, and a slider 206 is slidably installed inside the groove 205. By starting the servo motor 203, the reciprocating lead screw 201 is driven to rotate inside the mounting frame 1. The rotating reciprocating lead screw 201 drives the threaded sleeve seat 204 to reciprocate on the surface of the reciprocating lead screw 201 and the limiting rod 202. The reciprocating movement of the threaded sleeve seat 204 drives the spray head 404 to move laterally back and forth, which facilitates the spray head 404 to perform lateral reciprocating spraying on small sheet metal parts.

[0027] As one implementation method in this embodiment, such as Figure 1 and Figure 3 As shown, a second reciprocating mechanism 3 for longitudinal spraying of small sheet metal parts is provided inside the first reciprocating mechanism 2. The second reciprocating mechanism 3 includes a drive motor 301. The bottom end of the drive motor 301 is fixedly installed on one side of the top of the thread sleeve seat 204. The output end of the drive motor 301 is fixedly connected to a rotating rod 302 via a shaft. The bottom end of the rotating rod 302 extends through the interior of the thread sleeve seat 204 to the bottom end of the thread sleeve seat 204. A crank 303 is fixedly fitted onto the surface of the end of the rotating rod 302 away from the drive motor 301. The end of the crank 303 away from the rotating rod 302 is connected to a connecting rod 304 via a shaft. The top end of the connecting rod 304 away from the crank 303 is connected to a connecting vertical rod 305 via a shaft. The top of the connecting vertical rod 305 is fixedly connected to one side of the bottom of the slider 206. While the spray head 404 moves laterally back and forth, the drive motor 301 is started to drive the crank 303 to rotate at the bottom of the thread sleeve seat 204 through the shaft. The rotating rod 302 drives the crank 303 to rotate, and the rotating crank 303 drives the connecting rod 304 to rotate. The rotating connecting rod 304 drives the slider 206 to slide back and forth inside the slide groove 205 through the connecting vertical rod 305. The sliding slider 206 drives the spray head 404 to move longitudinally back and forth through the connecting plate 401 and the mounting base 402, which facilitates the spray head 404 to perform longitudinal back and forth spraying treatment on small sheet metal parts.

[0028] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the bottom end of the second reciprocating mechanism 3 is provided with a spraying mechanism 4 for spraying coatings onto small sheet metal parts. The spraying mechanism 4 includes a connecting plate 401, the bottom end of which is fixedly connected to the other side of the bottom end of the slider 206. The bottom end of the connecting plate 401 is fixedly connected to a mounting base 402, and the top end of the mounting base 402 is fixedly installed with a storage tank 403. The output end of the storage tank 403 extends through the interior of the mounting base 402 to the bottom end of the mounting base 402 via a pipe. The bottom end of the storage tank 403 is connected to a spraying head 404 via a pipe. The storage tank 403 stores the coating material for spraying small sheet metal parts. By opening the spraying head 404, the coating material stored in the storage tank 403 is evenly sprayed onto the surface of the small sheet metal parts. The horizontal reciprocating movement of the threaded sleeve 204, combined with the vertical reciprocating movement of the slider 206, drives the spraying head 404 to facilitate all-round spraying of small sheet metal parts.

[0029] Working principle: In use, the servo motor 203 drives the reciprocating screw 201 to rotate inside the mounting bracket 1. The rotating reciprocating screw 201 drives the sleeve seat 204 to reciprocate on the surface of the reciprocating screw 201 and the limiting rod 202. The reciprocating movement of the sleeve seat 204 drives the spray head 404 to reciprocate laterally. While the spray head 404 is reciprocating laterally, the drive motor 301 is started to drive the crank 303 to rotate at the bottom end of the sleeve seat 204 via the shaft. The rotating rod 302 drives the crank 303 to move laterally. The rotating crank 303 drives the connecting rod 304 to rotate. The rotating connecting rod 304 drives the slider 206 to reciprocate inside the slide groove 205 through the connecting vertical rod 305. The reciprocating slider 206 drives the spray head 404 to move longitudinally through the connecting plate 401 and the mounting base 402. The lateral reciprocating movement of the threaded sleeve 204, combined with the longitudinal reciprocating movement of the slider 206, drives the spray head 404 to perform all-round spraying treatment on the small sheet metal parts, realizing the function of simultaneous spraying treatment of small sheet metal parts in two directions.
