Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic products, especially to a spraying device with multi-directional spraying function. BACKGROUND

[0002] Plastic products are high molecular compounds polymerized through polyaddition or polycondensation reaction, commonly known as plastics or resins, which can be freely changed in composition and shape style. Plastic products are made of plastic as the main raw material and are processed into various plastic products or components by injection, extrusion, and hollow molding technology. During the production and manufacturing process of plastic products, spraying and film coating operations are often required on the surface of plastic products.

[0003] After searching, it was found that Chinese patent publication No. CN218308726U discloses a surface spraying device for plastic products, which comprises a spraying machine body provided with a support column. The support column is rotatably connected with a hanging plate on the outside. In the utility model, the hanging plate is rotatably connected with a hanging column at both ends, and the bottom of the hanging column is fixedly connected with a clamping mechanism. When the clamping mechanism at one end of the hanging plate carries the plastic product to the spraying station, the hanging column rotates to drive the plastic product to rotate and achieve full spraying. At the same time, the clamping mechanism at the other end of the hanging plate can feed, thereby realizing the function of simultaneous operation of spraying and feeding, and greatly improving the spraying efficiency.

[0004] The above-mentioned scheme has the advantage of improving the spraying efficiency, but in actual use, the surface of the plastic product is blocked by the clamping block, resulting in that some areas cannot be sprayed, and manual re-spraying is required, which is relatively cumbersome.

[0005] Therefore, it is urgent to provide a spraying device with multi-directional spraying function to solve the above-mentioned problems. UTILITY MODEL CONTENT

[0006] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art that the surface of the plastic product is blocked by the clamping block during actual use, resulting in that some areas cannot be sprayed, and manual re-spraying is required, which is relatively cumbersome. A spraying device with multi-directional spraying function is provided.

[0007] To solve the above-mentioned technical problems, one technical scheme adopted by the utility model is to provide a spraying device with multi-directional spraying function, which comprises a support column and a turntable arranged at the top of the support column. The outer side of the turntable is provided with a clamping assembly.

[0008] The clamping assembly includes a support plate installed on the outside of the turntable, a vertical tube fixedly installed on the top surface of the support plate, a fixed seat installed at the bottom of the vertical tube, a first limiting unit installed at the bottom of the fixed seat, a second limiting unit installed at the bottom of the first limiting unit, and a lifting unit installed at the top of the second limiting unit.

[0009] The present invention is further configured such that: a mounting plate is installed at the bottom of the support column, and a mounting hole is provided on the top surface of the mounting plate.

[0010] The present invention is further configured such that: the top of the support column is provided with an installation groove, the bottom of the installation groove is provided with a rotating component, and the turntable is installed at the end of the output shaft of the rotating component.

[0011] The present invention is further configured such that: there are multiple sets of clamping components, and the multiple sets of clamping components are distributed in a circular array with the center point of the turntable as the center.

[0012] The present invention is further configured such that: there are two sets of the first limiting unit, and the two sets of the first limiting unit are arranged opposite to each other on the outside of the vertical tube;

[0013] The first limiting unit includes a guide rod installed on the outer surface of the vertical tube, a guide sleeve movably disposed on the outside of the guide rod, an extrusion member disposed on the side of the guide sleeve, a slider installed at the bottom of the guide sleeve, and a first clamping plate installed at the bottom of the slider. The slider is movably connected to the side wall of the fixed seat.

[0014] The present invention is further configured such that: the second limiting unit includes a U-shaped frame disposed at the bottom of the fixed base, a pusher disposed opposite to the side wall of the U-shaped frame, and a second clamping plate installed at the end of the output shaft of the pusher.

[0015] The present invention is further configured such that: the lifting unit includes an L-shaped plate installed on the top of the support plate, a lifting component installed on the top of the L-shaped plate, and a movable rod installed at the end of the output shaft of the lifting component, the bottom of the movable rod being fixedly connected to the top of the U-shaped frame.

[0016] The present invention is further configured such that a drying component is provided on the outer side of the support column;

[0017] The drying assembly includes a drying box installed on the outside of the support column, an air-gathering duct set on the top edge of the drying box, the air-gathering duct being located directly below the clamping assembly, and an air supply pipe installed on the side wall of the drying box.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model connects the external heating pipe and the air supply pipe through the clamping assembly, then places the plastic product between two second clamping plates, and pushes the second clamping plates closer to the plastic product with the output shaft of the pusher to clamp the plastic product. Then, it sprays the surface of the plastic product with the help of the spraying device.

[0020] In conjunction with the lifting mechanism, the movable rod moves upward, which in turn moves the U-shaped frame and the plastic product at its bottom upward. During the upward movement, the plastic product squeezes the first clamping plates on both sides, causing them to move outward. The elastic squeezing action of the extrusion component pushes the guide sleeve, which in turn pushes the two first clamping plates to clamp the plastic product. Then, with the action of the pushing component, the second clamping plate separates from the plastic product. Finally, with the help of the spraying device, the remaining area of ​​the plastic product is sprayed, thus achieving all-round spraying of the plastic product and improving spraying efficiency.

[0021] 2. This utility model uses a drying component to allow hot air to enter the drying chamber through an air duct and then be blown onto the surface of the plastic product through an air concentrator, thereby drying the plastic product and further improving the spraying efficiency.

By setting multiple sets of clamping components 3, multiple plastic products can be sprayed in sequence, which improves the spraying efficiency.

[0033] There are two sets of first limiting units 34, and the two sets of first limiting units 34 are arranged opposite to each other on the outside of the vertical tube 32.

[0034] The first limiting unit 34 includes a guide rod 341 installed on the outer surface of the vertical tube 32, a guide sleeve 342 movably disposed on the outside of the guide rod 341, a pressing member 343 disposed on the side of the guide sleeve 342, a slider 344 installed on the bottom of the guide sleeve 342, and a first clamping plate 345 installed on the bottom of the slider 344. The slider 344 is movably connected to the side wall of the fixed seat 33. Preferably, the pressing member 343 is a compression spring.

[0035] The second limiting unit 35 includes a U-shaped frame 351 disposed at the bottom of the fixed base 33, a pusher 352 disposed opposite to the side wall of the U-shaped frame 351, and a second clamping plate 353 installed at the end of the output shaft of the pusher 352.
