Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic reciprocating material spraying device. Background Art

[0002] In the process of continuous production of FRP flat plates by machine, the use of coatings is crucial. It can not only improve the appearance quality of products, but also enhance the durability and protection performance of products. At present, when continuously producing FRP flat plates by machine, it is necessary to adjust the scraping knife on the production table to scrape resin through a scraping device (such as a multi-point adjustable tool rest), and then lay glass fiber on the resin surface. The resin penetrates the glass fiber from bottom to top. The thinner the product, the easier and faster the penetration. However, for some flat plates with a larger thickness (such as more than 4 mm), it is difficult for the resin to penetrate to the top layer. At this time, it is necessary to spray resin on the glass fiber surface to infiltrate the upper layer of glass fiber. However, the upper layer material spraying work is all realized by manual material spraying, resulting in a slow material spraying speed, and often there will be situations such as material breakage or uneven material spraying, which greatly affects the production efficiency.

[0020] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 2 shown, a specific embodiment of the present utility model provides an automatic reciprocating spraying device, including a mounting frame 1, a feeding and conveying mechanism 2, a stirring and spraying mechanism 3, and a reciprocating movement mechanism 4. Both ends of the mounting frame 1 are installed on a production table 5. A slide rail 11 is provided on the mounting frame 1, and the slide rail 11 is located above the plate working area 51 of the production table 5. A slide rail seat 12 slidably connected to the slide rail 11 is provided on the slide rail 11.

[0022] The stirring and coating mechanism 3 is installed on the slide rail base 12 so that the stirring mechanism can perform the coating operation on the processed plates in the plate working area 51 below the slide rail 11. The feeding end of the stirring and coating mechanism 3 is connected to the discharging end of the feeding and conveying mechanism 2. The feeding and conveying mechanism 2 automatically conveys the coating material into the stirring and coating mechanism 3 to realize the automatic feeding function, which is convenient for the subsequent coating operation of the stirring and coating mechanism 3. The discharging end of the stirring and coating mechanism 3 faces the plate working area 51. The stirring and coating mechanism 3 is used to stir the coating material conveyed by the feeding and conveying mechanism 2 evenly and then feed the processed plates in the plate working area 51 through the discharging end, so that the coating material can fully penetrate and infiltrate into the upper glass fiber of the thicker processed plates, meet the production and processing requirements of different thick plates, and thus realize the automatic coating function for thick plates.

[0023] The reciprocating movement mechanism 4 is arranged on the slide rail base 12. The reciprocating movement mechanism 4 is used to drive the slide rail base 12 and the stirring and coating mechanism 3 on the slide rail base 12 to reciprocate on the slide rail 11. The reciprocating movement mechanism 4 drives the stirring and coating mechanism 3 to reciprocate above the plate working area 51 to perform reciprocating coating on the upper surface of the processed plates during transportation, realizing the automatic reciprocating coating function.

[0024] Therefore, the utility model does not require manual coating, has low labor cost, high coating efficiency, and can effectively avoid abnormal situations such as unstable feeding and uneven coating caused by human factors. It can adapt to the production requirements of different thick plates, and has high production efficiency and stability.

[0025] Specifically, as Figures 1 to 2 and Figure 4As shown in the figure, the reciprocating movement mechanism 4 includes a reciprocating control device 41 and a reciprocating movement device 42. The reciprocating movement device 42 is used to drive the stirring and spraying mechanism 3 to reciprocate on the slide rail 11. The reciprocating control device 41 includes a DC power supply 411, a relay 412, an induction device 413 and an electromagnetic steering valve 414. The relay 412 is electrically connected to the DC power supply 411, the induction device 413 and the electromagnetic steering valve 414 respectively. The induction device 413 is arranged at both ends of the slide rail 11 respectively, and is used to detect the in-place signal of the stirring and spraying mechanism 3. When the induction device 413 detects that the stirring and spraying mechanism 3 has moved in place, it will send an induction signal to the relay 412, and amplify the induction signal through the relay 412 to drive the electromagnetic steering valve 414. The electromagnetic steering valve 414 is electrically connected to the reciprocating movement device 42, and is used to drive the reciprocating movement device 42 to perform steering movement work according to the received in-place signal. When the left in-place signal or the right in-place signal of the stirring and spraying mechanism 3 is detected, the reciprocating movement device 42 is controlled to drive the stirring and spraying mechanism 3 to move to the right or left on the slide rail 11, that is, to perform steering movement work, so as to reciprocally spray the upper surface of the processed sheet being conveyed, and realize the automatic reciprocating spraying function.

[0026] Among them, the reciprocating movement device 42 includes a reciprocating drive motor 421, a gear 422 and a rack 423. The rack 423 is installed on one side wall of the slide rail 11; the reciprocating drive motor 421 is arranged on the slide rail seat 12, the drive shaft of the reciprocating drive motor 421 is connected to the gear 422, and the gear 422 is meshed with the rack 423; the electromagnetic steering valve 414 is electrically connected to the reciprocating drive motor 421. After being powered on, the reciprocating drive motor 421 drives the gear 422 to rotate. Under the cooperation of the gear 422 and the rack 423, the stirring and spraying mechanism 3 is driven to move to the left or right. When the induction device 413 detects the in-place signal, the electromagnetic steering valve 414 is electrically connected to the reciprocating drive motor 421, and is used to drive the reciprocating drive motor 421 to perform reverse rotation work according to the corresponding in-place signal, so as to drive the stirring and spraying mechanism 3 to move in the reverse direction, thereby realizing the automatic reciprocating spraying function.

[0027] Preferably, the induction device 413 is detachably installed on the slide rail 11. According to the thickness of the actual processed sheet, the position of the induction device 413 can be adjusted accordingly, so that the distance between the two induction devices 413 is slightly greater than or equal to the thickness of the processed sheet, so that the reciprocating stirring and spraying mechanism 3 can reciprocally spray the processed sheet below, ensuring that the wide surface of the processed sheet can be fully sprayed, improving the spraying effect, and being able to adapt to processed sheets of different widths for spraying, with a wide adaptation range.

[0028] Preferably, the induction device 413 is preferably a magnetic induction switch, but is not limited thereto, and may also be other induction devices 413 with position detection or distance detection. When the slide rail seat 12 and the electronic device with magnetism on the slide rail seat 12 approach the magnetic induction switch, the magnetic induction switch will sense the in-place signal and send it to the electromagnetic steering valve 414 to drive the reciprocating drive motor 421 to perform steering and moving work.

[0029] Furthermore, as Figures 1 to 3 shown, the stirring and pouring mechanism 3 includes a stirring tank 31, a stirring motor 32 and a first frequency converter 33. The first frequency converter 33 is electrically connected to the stirring motor 32, and the rotation speed and torque of the stirring motor 32 are precisely controlled through the first frequency converter 33, so as to ensure high-precision stirring and pouring processing work. The stirring tank 31 and the stirring motor 32 are installed on the slide rail seat 12. The stirring tank 31 is provided with a discharge port 311, and the paint output through the discharge port 311 acts on the plate working area 51. The stirring rod 312 of the stirring motor 32 and the discharge end of the feeding and conveying mechanism 2 both extend into the stirring tank 31. The stirring rod 312 is used to stir the paint in the stirring tank 31 to stir the paint evenly, and the fully stirred paint is poured downward through the discharge port 311 of the stirring tank 31, so that the paint acts on the surface of the processed plate, so as to achieve sufficient penetration and infiltration to meet the production and processing requirements of different thick plates, thereby realizing the automatic pouring function of thick plates.

[0030] Preferably, as Figure 3 shown, an electric valve 313 is provided in the discharge port 311. By setting the electric valve 313, its opening and closing degree can be controlled, so as to control the flow rate of the poured material, so as to better meet the production and processing requirements of different thick plates.

[0031] Preferably, as Figure 3 shown, a plurality of liquid level detection sensors 314 are arranged at intervals along the height direction on the inner wall of the stirring tank 31, including at least a high-level detection sensor 3141 higher than the discharge port 311 and a low-level detection sensor 3142 slightly lower than the discharge port 311. For example, when the high-level detection sensor 3141 detects a high-level signal, it means that the paint in the current stirring tank 31 is full, and at this time, the feeding and conveying mechanism 2 can stop feeding; when the low-level detection sensor 3142 detects a low-level signal, it means that the paint is insufficient, and at this time, the feeding and conveying mechanism 2 continues to feed, so as to realize the automatic feeding function.

[0032] Furthermore, as Figures 1 to 2As shown in the figure, the feeding and conveying mechanism 2 includes a feeding driving device 21 and a material conveying pipe 22. The input ends of the feeding driving device 21 are respectively connected to the first feeding tank and the second feeding tank. The first feeding tank is a resin tank, and the second feeding tank is preferably a curing agent tank. The output end of the feeding driving device 21 is communicated with the mixing tank 31 through the material conveying pipe 22. The feeding driving device 21 can output the coatings in the first feeding tank and the second feeding tank to the mixing tank 31, so that the mixing tank 31 can uniformly mix the coatings.

[0033] Wherein, the feeding driving device 21 includes a duplex pump, and a second frequency converter is arranged in the duplex pump. The feeding flow rate of the duplex pump can be controlled by the second frequency converter. The coatings in the first feeding tank and the second feeding tank are conveyed to the mixing tank 31 through the material conveying pipe 22 by the duplex pump, realizing the automatic feeding function.

[0034] Preferably, the electronic device of the present invention is electrically connected to an external controller to realize corresponding electric control functions.

[0035] In summary, the present invention does not require manual pouring of materials, has low labor costs, high pouring efficiency, and effectively avoids abnormal situations such as unstable feeding and uneven pouring caused by human factors. It can meet the production requirements of processed plates with different thicknesses and widths, and has high production efficiency and stability.

[0036] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
