Description

Technical Field

[0001] This utility model relates to the field of wood-plastic pencil production technology, specifically a spray painting and coloring device for wood-plastic pencil production. Background Technology

[0002] Wood-plastic composite pencils are pencils made primarily from wood and plastic. The process involves extruding the lead and barrel together using an extruder, then placing them in a water-cooling box. After cooling and setting, they are cut into pencil blanks of a fixed length using a shearing device. After being smoothed by an end-grinding device, the circumference of the pencil is painted to enhance its color and improve its appearance.

[0003] When painting wood-plastic pencils, a conveyor device carries the upright wood-plastic pencil through the painting area. The painting operation of the painting device is used to paint the end of the pencil (i.e., the top part of the upright pencil). This allows the beginning and end of the pencil to have different colors. Afterwards, the wood-plastic pencil needs to be removed manually. To simplify this operation, a painting device for wood-plastic pencil production is provided. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6 In this embodiment of the present invention, a spray painting and coloring device for wood-plastic pencil production includes a main body 1 consisting of a base 101, a first L-shaped bracket 102, an outer limiting rail 103, an inner limiting top plate 104, a conveying roller 105, a conveyor belt 106, and a drive motor 107. The outer limiting rail 103 and the inner limiting top plate 104 are distributed above the base 101. The outer limiting rail 103 is welded and fixed to the base 101 through the first L-shaped bracket 102, and the inner limiting top plate 104 is fixed through a central support. The column is fixedly connected to the top of the base 101. The conveyor roller 105 and the conveyor belt 106 are distributed between the base 101 and the inner limiting top plate 104. The conveyor belt 106 is sleeved on the outside of the conveyor roller 105. The drive motor 107 is installed at the bottom of the base 101 and the output end of the drive motor 107 passes through the base 101 and is connected to a conveyor roller 105. The outer side of the conveyor belt 106 and the lower part of the outer limiting rail 103 are provided with a conveying assembly 2. The conveying assembly 2 is used to realize the conveying operation of wood-plastic pencils.

[0035] Conveying assembly 2 includes a conveying unit, a rotation unit, and an unloading unit;

[0036] The conveying unit operates along with the conveyor belt 106 to move and convey the wood-plastic pencils through the painting area.

[0037] The self-rotating unit is used to drive the rotating parts in the conveying unit to rotate, thereby driving the wood-plastic pencil to rotate, thus realizing the all-round coloring operation at the tail end of the wood-plastic pencil.

[0038] The unloading unit is used to flip the conveying unit and eject the wood-plastic pencils, thereby realizing the automatic unloading operation of the wood-plastic pencils;

[0039] The conveying unit includes a mounting base 201, a rotating arm 202, a return torsion spring 203, a tilting base 204, and a rotating drum 205;

[0040] Mounting base 201 is fixedly installed on the outside of conveyor belt 106. Rotating arm 202 is rotatably connected to the inside of mounting base 201 through fixed shaft. Return torsion spring 203 is sleeved on the outside of fixed shaft and the two ends of return torsion spring 203 are respectively snapped into the outside of rotating arm 202 and fixed shaft.

[0041] The flipping seat 204 is fixed to one side of the rotating arm 202. The rotating cylinder 205 is rotatably connected to the inner side of the flipping seat 204 and extends through the upper and lower ends of the rotating cylinder 205. The flipping seat 204 is distributed between the outer limiting rail 103 and the inner limiting top plate 104. The top of the rotating cylinder 205 protrudes from the top of the outer limiting rail 103 and the top of the inner limiting top plate 104.

[0042] The top groove of the rotating drum 205 is used for inserting wood-plastic pencils, and the conveyor belt 106 drives the rotating drum 205 to move, thereby realizing the conveying of wood-plastic pencils.

[0043] The self-rotating unit includes a driven gear 206, a second L-shaped bracket 212, and a fixed gear plate 213;

[0044] Driven gear 206 is fixed to the bottom outer side of the rotating drum 205, and fixed tooth plate 213 is fixed to the bottom of the outer limit rail 103 through the second L-shaped bracket 212, and the horizontal height of fixed tooth plate 213 matches that of driven gear 206.

[0045] The driven gear 206, which moves closer to the fixed gear plate 213, meshes with the fixed gear plate 213. The fixed gear plate 213 limits the movement of the driven gear 206, causing the driven gear 206 to rotate, thereby enabling the rotating drum 205 to drive the wood-plastic pencil to rotate.

[0046] The unloading unit includes a pressure block 207, a push rod 208, a limit block 209, a return spring 210, an L-shaped pressure block 211, and a fixed pressure block 214;

[0047] The outer limiting rail 103 has a discharge port 108 that passes through the upper and lower ends of the outer limiting rail 103 and the other side. The fixing block 214 is fixed to the bottom of the outer limiting rail 103 and distributed below the discharge port 108.

[0048] The pressure block 207 is fixed to one side of the tilting seat 204. When the pressure block 207 moves to the area of ​​the discharge port 108, it presses against the fixed pressure block 214 to provide power for the rotation of the tilting seat 204.

[0049] The top rod 208 is vertically slidably connected to the inside of the rotating drum 205 and passes through the bottom of the rotating drum 205. The limiting block 209 is fixed to the outside of the top rod 208. The return spring 210 is sleeved on the outside of the top rod 208. The limiting block 209 and the return spring 210 are distributed inside the rotating drum 205 and the return spring 210 is located at the top of the limiting block 209. The flipping seat 204 is provided with a telescopic groove for the limiting block 209 to move up and down.

[0050] The L-shaped pressure block 211 is fixed at the bottom of the mounting base 201 and extends to the bottom of the top rod 208. The rotating flipping base 204 drives the bottom of the driven gear 206 to press against the L-shaped pressure block 211. The driven gear 206 is forced to move upward and push the wood-plastic pencil on the inner side of the top of the flipping base 204, thereby realizing the automatic unloading of the wood-plastic pencil.

[0051] In this embodiment, it should be noted that the painting equipment is positioned aligned with the fixed toothed plate 213. It should also be noted that the central column is located at the bottom center of the inner limiting top plate 104 and will not interfere with the operation of the conveyor belt 106.

[0052] The operating principle of this device is as follows:

[0053] At the loading station, insert the wood-plastic pencil into the inside of the rotating drum 205, start the drive motor 107, and the drive motor 107 drives the conveyor belt 106 to rotate through the conveyor roller. The conveyor belt 106 drives the mounting base 201, rotating arm 202, tilting seat 204, and rotating drum 205 to move as a whole towards the painting equipment area (it should be noted that at this time, the rotating arm 202 and tilting seat 204 remain horizontal under the support of the return torsion spring 203, and the rotating drum 205 remains vertical).

[0054] When the wood-plastic pencil is moved to the painting area, the flipping seat 204 approaches the fixed toothed plate 213, and the driven gear 206 meshes with the fixed toothed plate 213. The wood-plastic pencil passing through the painting area is painted. At the same time, the driven gear 206 rotates under the limiting action of the fixed toothed plate 213, thus realizing the rotation operation of the wood-plastic pencil, thereby realizing the all-round painting operation of the wood-plastic pencil (it should be added that: a rubber ring is provided on the inner wall of the rotating drum 205 to increase the friction between the rotating drum 205 and the wood-plastic pencil, thereby realizing the stable rotation of the wood-plastic pencil).

[0055] The colored wood-plastic pencils are continuously conveyed to the discharge port 108. At this time, the pressure block 207 contacts the fixed pressure block 214, and the pressure block 207 is subjected to the squeezing force from the fixed pressure block 214. This squeezing force causes the tilting seat 204 and the rotating arm 202 to rotate around the fixed shaft (it should be noted that the fixed shaft and the mounting seat 201 are fixedly connected). The reset torsion spring 203 is subjected to force and twists and deforms, and the tilting seat 204 tilts so that the top of the rotating drum 205 faces the outside of the outer limit rail 103. At the same time... The bottom of the push rod 208 rotates and presses against the top of the horizontal part of the L-shaped pressure block 211. The push rod 208 moves upward along the inner wall of the rotating drum 205 and drives the limiting block 209 to compress and contract the return spring 210. The upward-moving push rod 208 can compress the bottom of the wood-plastic pencil, causing the wood-plastic pencil to move upward. The wood-plastic pencil that moves upward at an angle eventually separates from the rotating drum 205 and flies out to the outside of the outer limiting rail 103 (a corresponding collection device is provided outside). In this way, the automatic unloading of the wood-plastic pencil is realized.

[0056] Once the flipping seat 204, which has passed through the area of ​​the fixed pressure block 214, loses external pressure, it returns to its initial state under the action of the reset torsion spring 203. The push rod 208 also returns to its initial state under the action of the reset spring 210. Then it is driven to the loading station by the conveyor belt 106. By repeating this process, the painting and automatic unloading of wood-plastic pencils can be achieved.

[0057] Please refer to this carefully. Figures 1-6 The top edge of the pressure block 207 near the fixed pressure block 214 has an arc-shaped structure, and the bottom edge of the fixed pressure block 214 near the pressure block 207 has an arc-shaped structure.

[0058] In this embodiment, this structure allows for a change in force deflection when the pressure block 207 contacts the fixed pressure block 214.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
