Description

Technical Field

[0001] The invention belongs to the technical field of plastic processing, and in particular relates to a plastic part immersion device. Background Art

[0002] After injection molding, nylon plastic products need to be placed in water. With the help of the hygroscopicity of nylon materials, they can absorb saturated water to achieve the best toughness. At the same time, nylon plastics of different thicknesses require different soaking times in water. In the prior art, workpieces are soaked manually, which is inefficient, labor-intensive, and the soaking time cannot be guaranteed, seriously affecting the quality of the workpiece. The automatic immersion and drying equipment disclosed in the utility patent with application number 201510195385.6 uses a robot to grab the workpiece and shift it between the immersion station and the drying station, so the number of robots directly affects the processing efficiency. Summary of the invention

[0003] The object of the present invention is to provide a plastic part immersion device, which realizes the immersion and transfer of workpieces by means of a rotating wheel, and has higher operating efficiency.

[0004] The objective of the present invention is achieved as follows: a plastic part immersion device comprises a water trough, one end of the water trough is a feed port, and the other end is a discharge port; a rotating wheel driven by a motor is mounted in the water trough, and two or more arc-shaped plates are distributed circumferentially on the rotating wheel, and water holes are arranged on the arc-shaped plates, and immersion stations are formed between the arc-shaped plates; when the arc-shaped plate rotates to the feed port, its arc-shaped concave surface faces the feed port, and when the arc-shaped plate rotates to the discharge port, its arc-shaped convex surface contacts the discharge port, and the surface height gradually decreases toward the discharge port.

[0005] Furthermore, a supporting inclined plate is installed between adjacent arc-shaped plates, and the supporting inclined plate faces the arc-shaped concave surface.

[0006] Furthermore, a partition is provided at the bottom of the water tank, which divides the water tank into a water immersion area and a cooling water area which are not connected to each other, and the arc plate is located in the water immersion area.

[0007] Furthermore, the partition is arc-shaped.

[0008] Furthermore, the cooling water area is provided with a water inlet port and a water outlet port which are connected with an external water source.

[0009] Furthermore, the discharge port is equipped with a discharge inclined rail, and drying ports are arranged on both sides of the discharge inclined rail.

[0010] Furthermore, a water level detector for detecting the water level is provided in the immersion area.

[0011] Furthermore, an infrared sensor for detecting workpieces is arranged on the feeding track to which the feeding port is connected.

[0012] Furthermore, the rotation angle of the rotating wheel is controlled by an angle sensor.

[0013] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0014] 1. Each immersion station has an arc-shaped concave surface and an arc-shaped convex surface on both sides. The arc-shaped plate concave surface structure can effectively hold the workpiece, and the immersion time is controlled by the motor; the arc-shaped plate convex surface structure can form an inclined feeding surface to transfer the water-saturated workpiece out of the immersion device.

[0015] 2. After the workpiece is immersed in water, it can evaporate the surface moisture with the help of its own residual heat after leaving the equipment through the discharging inclined rail.

[0016] 3. The partition at the bottom of the water tank separates the water tank into a soaking area and a cooling water area, preventing the highly polluted water in the soaking area from being directly discharged to the outside, thereby reducing environmental pollution.

[0017] 4. The drying ports on both sides of the discharging ramp exhaust air outwards through the blower, which can accelerate the evaporation of moisture on the workpiece surface.

[0018] 5. The water level detector in the flooded area is convenient for adding water to the tank through a water pump when the water level is lower than the rated height, or for sounding an alarm to remind the operator to add water. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0024] A plastic part immersion device, combined with Figure 1 and Figure 2, including a water tank 1 supported by a bracket, a rotating wheel 8 is set in the water tank 1, and arc plates 6 are distributed circumferentially on the rotating wheel 8. There are more than two arc plates 6. In this embodiment, the number of arc plates 6 is greater, forming multiple immersion stations, and water holes 6a are set on the arc plates 6; a feed ramp 3 and a discharge ramp 4 are set at both ends of the water tank 1. The feed ramp 3 is preferably set at a high place to facilitate the free sliding of the workpiece; the discharge ramp 4 is set at a low place to facilitate the transportation of the workpiece on the arc plate 6. Among them, when the arc plate 6 rotates to the feed port, its arc concave surface faces the feed port, and when the arc plate 6 rotates to the discharge port, its arc convex surface contacts the discharge port.

[0025] Look specifically Figure 3 A support inclined plate 5 is arranged between two adjacent arc-shaped plates 6, so that the structural strength between the arc-shaped plates 6 is better; at the same time, the outer surface of the support inclined plate 5 faces the concave surface of the arc-shaped plate 6, so that the support inclined plate 5 and the convex surface of the arc-shaped plate 6 form a transfer surface with a gradually decreasing height. Figure 1 As shown, when the arc plate 6 is docked on the discharge ramp 4, the workpiece can be smoothly transferred to the discharge ramp 4.

[0026] The rotating wheel 8 is driven to rotate by a motor 7, and the motor 7 is preferably arranged below the water tank 1. At the same time, in order to control the speed and rotation angle of the rotating wheel 8, an angle sensor 9 for detecting the rotation angle of the rotating wheel 8 is installed on the side wall of the water tank 1, and cooperates with the infrared sensor 10 on the feeding ramp 3 to adjust the immersion time of the workpiece to ensure that the workpiece can be saturated with water.

[0027] like Figure 2 As shown, a partition 2 is provided at the bottom of the water tank 1, and the partition 2 divides the water tank 1 into a water immersion area A and a cooling water area B which are not connected to each other. The arc plate 6 is located in the water immersion area A; and the partition 2 is preferably arranged in an arc shape to better fit the rotation track of the arc plate 6. When the immersion station is docked with the feed ramp 3, the arc plate 6 receiving the workpiece below should be at a certain distance below the water level of the immersion area A, so that the workpiece falling into the immersion area A can be buffered by water to a certain extent, avoiding direct impact on the arc plate 6 to cause deformation.

[0028] The cooling water area B is provided with a water inlet port and a water outlet port connected to an external water source, and the temperature in the immersion area A is taken away by the water flowing in the cooling water area B.

[0029] Among them, drying ports are preferably arranged on both sides of the discharging inclined rail 4, and air is exhausted outwards by a blower, which can accelerate the evaporation of water on the surface of the workpiece.

[0030] Furthermore, a water level detector for detecting the water level is provided in the immersion area A to alarm and remind the operator to add water or automatically add water through a water pump.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
