The aforementioned portable forks made of paper and wood usually undergo the process of pressing and cutting the sheet materials, while portable forks made of plastic are usually made using an integrated injection molding process. The aforementioned process is usually accompanied by the generation of a large amount of debris (such as paper scraps, wood chips and plastic particles, etc.). For portable forks made using the injection molding process, the molded fork products may also have residual wire drawing, overflow, etc. In order to ensure product quality and prevent the aforementioned debris and particles from being ingested by the user during the use of the fork, a cleaning process should be introduced in the production process of portable forks. By applying a cleaning operation to the product, the aforementioned debris, particles and product burrs can be removed to improve product quality.

[0003] For automated production lines, higher production efficiency has brought about an increase in fork production capacity.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0020] See Figure 1 、 Figure 2 and Figure 3 The portable fork production cleaning device of the present invention includes two belt racks 7 arranged opposite to each other, a belt roller 9 and a conveyor belt 6 are installed in each belt rack 7, and a belt motor 13 is also installed on the belt rack 7 to drive the belt roller 9 located at the end position.

[0021] Therefore, the cleaning device includes two belt conveyors arranged opposite to each other, and the conveyor belts 6 of the two belt conveyors are arranged in the vertical direction, that is, the belt surface of the conveyor belt 6 is parallel to the vertical direction. In this embodiment, the belt frame 7 includes a frame top plate and a frame bottom plate, and the roller shafts of each belt roller 9 are fixedly mounted between the frame top plate and the frame bottom plate. A tensioning roller 5 for tensioning the conveyor belt 6 is also installed between the middle portions of the frame top plate and the frame bottom plate.

[0022] The belt rollers 9 in the middle are used to stably support the conveyor belt 6, and the tensioning roller 5 is used to keep the conveyor belt 6 in a tensioned state to avoid loosening during operation. Figure 1 As shown in FIG, the frame top plate and the frame bottom plate of the belt frame 7 are spaced a certain distance apart, so that the two belt conveyors are transparent in the horizontal direction, allowing air flow to pass through.

[0023] The apparatus also includes a spacing adjustment assembly for adjusting the movement of the two belt frames 7 toward or away from each other. The two conveyor belts 6 rotate in opposite directions, and the forks 8 are held and conveyed by the two conveyor belts 6. The spacing adjustment assembly drives the two belts toward each other, reducing the distance between the two conveyor belts 6 to an appropriate level. The two conveyor belts 6 can then grip the handles of the forks 8. Since the two conveyor belts 6 move at the same speed and in opposite directions, the forks 8 are simultaneously held by the two conveyor belts 6 and conveyed backwards.

[0024] like Figure 2 As shown in the figure, the upper conveyor belt 6 rotates and moves in a clockwise direction, and the lower conveyor belt 6 rotates and moves in a counterclockwise direction, and the speeds of the two are equal, so that the fork 8 located in the gap between the two conveyor belts 6 and clamped by the two conveyor belts 6 is transported and transferred from the right end to the left end.

[0025] In this embodiment, the spacing adjustment assembly includes a support 4, on which a forward and reverse helical screw 16 is mounted, and operating handwheels 3 are mounted at both ends of the forward and reverse helical screw 16. A translation base 15 is mounted on both the forward and reverse helical portions of the forward and reverse helical screw 16, and the frame bottom plates of the two belt racks 7 are respectively fixedly connected to the two translation bases 15. The purpose of providing the operating handwheel 3 is to improve the convenience of operating the forward and reverse helical screw 16. When the forward and reverse helical screw 16 rotates in the forward direction, the two translation bases 15 drive the two belt racks 7 to move toward each other, reducing the distance between the conveyor belts 6. Conversely, when the forward and reverse helical screw 16 rotates in the reverse direction, the two translation bases 15 drive the two belt racks 7 to move away from each other, increasing the distance between the conveyor belts 6.

[0026] In this embodiment, guide rods 17 are mounted on the support 4 on both sides of the forward and reverse screws 16. Guide holes are provided through the two translation bases 15 at corresponding locations, and the two guide rods 17 are positioned within the corresponding guide holes. The provision of guide rods 17 in conjunction with the guide holes in the translation base 15 significantly improves the stability of the translation base 15 and the belt frame 7 during displacement.

[0027] A cleaning assembly is installed on both belt racks 7. When the fork 8 is transported from the right end to the left end, it passes through the cleaning assembly. Under the action of the cleaning assembly, the fork 8 is cleaned to remove debris, particles, and edge burrs such as wire drawing and overflow that may remain during injection molding on the exposed part of the fork 8, that is, the fork head. This makes the fork 8 clean and the edges are trimmed, improving product quality and preventing users from ingesting foreign objects when using the fork 8 that has not been cleaned as described above. Generally, debris, particles, wire drawing, overflow, and other burrs on the fork 8 are located on the fork head, and it is also the fork head that comes into contact with the user's mouth during use. Therefore, the cleaning device chooses to clamp the handle portion of the fork 8 and perform the cleaning operation on the fork head.

[0028] The cleaning assembly includes a cleaning brush roller 11 mounted at the top center rear portion of the belt frame 7 and a brush roller motor 12 for driving the cleaning brush roller 11. The fork 8 passes between the two cleaning brush rollers 11. In this embodiment, the cleaning brush roller 11 includes a cylindrical brush roller body with a central axis. Axle seats are provided at both ends of the central axis and are fixed to the frame top plate of the belt frame 7. Flexible bristles extending radially are provided on the outer wall of the brush roller body.

[0029] The flexible bristles can be silicone bristles. When the cleaning brush roller 11 rotates, the flexible bristles act on the exposed portion of the fork 8, namely the fork head, and remove debris, particles, and burrs by applying moderate friction and whipping to the fork head. The two cleaning brush rollers 11 rotate at the same speed and in opposite directions, and the debris, particles, and burrs removed from the fork 8 are formed into dust and thrown upward.

[0030] A dust hood 10 is provided above the two cleaning components and is connected to a negative pressure pipe in the workshop. Dust generated and thrown upward by the cleaning brush roller 11 enters the dust hood 10 to prevent it from spreading to the surrounding area. In this embodiment, a fan can also be installed below the two cleaning components to blow air upward, thereby blowing upward the dust generated during the cleaning process.

[0031] It also includes a frame 1 with leveling feet, a support 4 is installed and fixed on the top of the frame 1, and a control box 2 is also installed on the frame 1. The control box 2 is provided with a speed knob for the belt motor 13 and a speed knob for the brush roller motor 12. These two speed knobs can be used to adjust the lateral speed of the fork 8 and the rotation speed of the cleaning brush roller 11 respectively: when there are many debris, particles and burrs on the fork 8, the moving speed of the conveyor belt 6 should be reduced, that is, the moving speed of the fork 8 should be reduced, and the rotation speed of the cleaning brush roller 11 should be increased. Conversely, when the fork 8 itself is relatively clean, the lateral speed of the fork 8 can be appropriately increased and the rotation speed of the cleaning brush roller 11 can be reduced.

[0032] A receiving conveyor belt 14 is provided below the ends of the two belt racks 7. The forks 8 passed through the cleaning assembly and transported laterally by the two conveyor belts 6 fall downward onto the receiving conveyor belt 14 after moving to the ends, and are transported backward along the receiving conveyor belt 14 to the packaging process.

[0033] Operation process:

[0034] The cleaning device for the production of portable forks is arranged behind the forming device of the forks 8. The right end of the gap between the two belt conveyors after the spacing adjustment should be docked with the discharge port of the forming device. After the forks 8 come out of the discharge port, they immediately enter between the head ends of the two conveyor belts 6, or a robot or other device is arranged between the forming device and the discharge port to actively place the forks 8 between the head ends of the two conveyor belts 6. Figure 1 As shown in;

[0035] The forks 8 are conveyed and transferred rearward, and when passing through the cleaning area where the two cleaning brush rollers 11 are located, debris, particles and burrs are removed by the friction and whipping action of the flexible bristles of the cleaning brush rollers 11; the cleaned forks 8 are finally discharged from the ends of the two conveyor belts 6, fall downward onto the receiving conveyor belt 14, and are conveyed and transferred to the packaging process at the rear.
