Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying device for surface treatment of molybdenum mandrels. Background Technology

[0002] To prevent spraying liquid from splashing and causing waste or environmental impact, existing spraying devices often install baffles on the back of the workpiece to block splashed spraying liquid, preventing environmental pollution and facilitating recycling. However, the spraying liquid is easily affected by gravity and flows into the transport, support, or clamping components, affecting the operation of the device components. For example, a double-sided protective self-adjusting spraying mechanism for building steel structures disclosed in Chinese Patent Application No. CN202220158073.3 sprays the outside of the building steel structure through a spray pipe. The main hydraulic rod drives the connecting plate to slide, and the spray pipe circulates spraying along both sides of the building steel structure. At the same time, the baffle plate moves with the spray pipe to block the spraying liquid splashed during the spraying process. However, the spraying liquid is easily affected by gravity and flows into the support components along the side of the building steel structure, affecting the operation of the hydraulic rods there. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a spraying device for surface treatment of molybdenum mandrels. When loading material, the operator simply inverts the molybdenum mandrel inside the hopper, rotates the rotary motor to rotate the lead screw and slide the slider to the top of the hopper, extends the telescopic rod to allow the grippers to enter the molybdenum mandrel, and starts the clamping motor to rotate the clamping disc. Because the surface of the clamping disc has outwardly spreading spiral patterns, the grippers are movably connected to it. The grippers are pressed against the clamping disc and its surface cover, moving to the periphery of the clamping disc, thereby pressing against the inner wall of the molybdenum mandrel and clamping it. The telescopic rod is then retracted to lower the material. The bucket is started by rotating the rotary motor and clamping motor, which move the molybdenum mandrel towards the front of the spray nozzle. The lead screw motor is started to rotate the rotating rod, which drives the connecting rod to move. The connecting rod drives the spray nozzle to move up and down repeatedly inside the slide rail. In conjunction with the rotary motor, the clamping components and the clamped molybdenum mandrel rotate, so that the molybdenum mandrel is sprayed evenly and thoroughly. Because the molybdenum mandrel is clamped upside down, the spray liquid will not contaminate the spraying components and the clamping and transporting components. Excess spray liquid that is sprayed onto the surface of the molybdenum mandrel will fall into the liquid collection tank due to gravity. Spray liquid that is not sprayed onto the surface of the molybdenum mandrel will be blocked by the baffle and slide into the liquid collection tank, which facilitates the recycling and reuse of the spray liquid.

[0004] This utility model also provides a spraying device for surface treatment of a molybdenum mandrel, comprising: a base, a telescopic rod fixedly connected to the upper surface of the base, a hopper fixedly connected to the output end of the telescopic rod, a liquid accumulation tank formed inside the base, and a baffle fixedly connected to the upper surface of the liquid accumulation tank; a bracket, fixedly connected to the upper surface of the base, a rotary motor fixedly connected inside the bracket, a rotating rod fixedly connected to the output end of the rotary motor, a connecting rod rotatably connected to the rotating rod, a fixed block rotatably connected to the end of the connecting rod away from the rotating rod, and a spray head fixedly connected inside the fixed block; a guide rail, a slider slidably connected inside the guide rail, a rotary motor fixedly connected inside the slider, a turntable fixedly connected to the output end of the rotary motor, a clamping motor fixedly connected inside the turntable, a clamping plate fixedly connected to the output end of the clamping motor, a spiral pattern formed inside the clamping plate, a gripper provided inside the spiral pattern, and a disc cover rotatably connected to the surface of the clamping plate. With the above components, when loading materials, the operator simply inverts the molybdenum mandrel inside the hopper, rotates the rotary motor to rotate the lead screw and slide the slider until it is directly above the hopper, extends the telescopic rod to allow the grippers to enter the molybdenum mandrel, and starts the clamping motor to rotate the clamping disc. Because the surface of the clamping disc has outwardly spreading spiral patterns, the grippers are movably connected to it. The grippers are pressed against the clamping disc and its surface cover, moving to the periphery of the clamping disc, thereby pressing against the inner wall of the molybdenum mandrel and clamping it. The telescopic rod is then retracted to lower the hopper, and the rotary motor and clamping motor are started to move the molybdenum mandrel. Move the lead screw motor forward to rotate the rotating rod. The rotating rod drives the connecting rod to move, and the connecting rod drives the nozzle to move up and down repeatedly inside the slide rail. This, in conjunction with the rotating motor, rotates the clamping component and the clamped molybdenum mandrel, allowing for even and thorough spraying of the molybdenum mandrel. Because the molybdenum mandrel is clamped upside down, the sprayed liquid will not contaminate the spraying component or the clamping and transporting component. Excess sprayed liquid that hits the surface of the molybdenum mandrel will fall into the liquid collection tank due to gravity. Sprayed liquid that does not hit the surface of the molybdenum mandrel will be blocked by the baffle and slide into the liquid collection tank, facilitating the recycling and reuse of the sprayed liquid.

[0005] According to the present invention, a spraying device for surface treatment of a molybdenum mandrel is provided in which a rotating groove is provided inside the bracket, and the rotating groove allows the rotating rod and the connecting rod to rotate during operation.

[0006] According to the present invention, a spraying device for surface treatment of molybdenum mandrel is provided with a slide rail on the side surface of the support, and the fixing block is slidably connected to the inner side wall of the slide rail.

[0007] According to the present invention, a spraying device for surface treatment of a molybdenum head is provided, wherein the spray head is connected to a liquid injection pipe, and the end of the liquid injection pipe away from the spray head is connected to a spraying liquid.

[0008] According to the present invention, a spraying device for surface treatment of a molybdenum mandrel is provided, wherein the disc cover is fixedly connected to the lower surface of the turntable, and the gripper is in the shape of an inverted "L".

[0009] According to the present invention, a spraying device for surface treatment of a molybdenum mandrel is provided, wherein the guide rail is disposed at the top of the bracket, and a lead screw motor is fixedly connected to the side surface of the bracket.

[0010] According to the present invention, a spraying device for surface treatment of a molybdenum mandrel is provided, wherein a lead screw is fixedly connected to the output end of the lead screw motor, and the lead screw is rotatably connected to the guide rail.

[0011] According to the present invention, a spraying device for surface treatment of a molybdenum mandrel is provided, wherein the lead screw is disposed inside the slider.

[0012] Beneficial effects:

[0013] Compared with existing technologies, this utility model allows workers to easily load molybdenum mandrels by simply inverting them inside the hopper, rotating the rotary motor to slide the slider onto the lead screw, and extending the telescopic rod to insert the grippers into the molybdenum mandrel. The clamping motor is then activated to rotate the clamping disc. Because the disc surface has outwardly spreading spiral patterns, the grippers are movably connected to it. The grippers are pressed against the disc and its surface cover, moving outwards to the sides of the disc and thus against the inner wall of the molybdenum mandrel, thereby clamping it. The telescopic rod is then retracted to lower the hopper, and the rotary motor and clamping motor are activated to transport the molybdenum mandrel towards the spray nozzle. At the front, the lead screw motor is started to rotate the rotating rod. The rotating rod drives the connecting rod to move, and the connecting rod drives the nozzle to move up and down repeatedly inside the slide rail. In conjunction with the rotating motor, the clamping component and the clamped molybdenum mandrel rotate, so that the molybdenum mandrel is evenly and thoroughly sprayed. Because the molybdenum mandrel is clamped upside down, the spray liquid will not contaminate the spraying component and the clamping and transport component, thus affecting the operation of each component. Excess spray liquid that is sprayed onto the surface of the molybdenum mandrel will fall into the liquid collection tank due to gravity. Spray liquid that is not sprayed onto the surface of the molybdenum mandrel will be blocked by the baffle and slide into the liquid collection tank, which facilitates the recycling and reuse of the spray liquid.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a spraying device for surface treatment of molybdenum mandrels, comprising: a base 1 supporting the entire device; a telescopic rod 2 fixedly connected to the upper surface of the base 1 for lifting and lowering a hopper 3; a hopper 3 fixedly connected to the output end of the telescopic rod 2 for holding the molybdenum mandrel; a liquid collection tank 4 inside the base 1 to collect excess spraying liquid, reducing waste and environmental impact; and a baffle 5 fixedly connected to the upper surface of the liquid collection tank 4 to block the spraying liquid that does not reach the surface of the molybdenum mandrel, allowing it to flow into the liquid collection tank 4 under the influence of gravity.

[0023] Support bracket 6 supports the spraying components and clamps the transport components. Support bracket 6 is fixedly connected to the upper surface of base 1, providing support for support bracket 6. A slide rail 20 is provided on the side surface of support bracket 6 for sliding of the fixed block 10. A rotary motor 7 is fixedly connected inside support bracket 6 to provide power to the crank-slider mechanism. A rotating rod 8 is fixedly connected to the output end of rotary motor 7 to transmit rotational power. The rotating rod 8 is rotatably connected to a connecting rod 9 to transmit power. A rotating groove 19 is provided inside support bracket 6, allowing the rotating rod 8 and connecting rod 9 to rotate during operation, enabling the crank-slider mechanism to operate normally. The end of connecting rod 9 away from the rotating rod 8 is rotatably connected to the fixed block 10, converting the rotational power into the displacement power of the fixed block 10, cooperating with the rotating rod 8 and connecting rod 9 to achieve... The fixed block 10 moves up and down reciprocally. The fixed block 10 is slidably connected to the inner wall of the slide rail 20, which limits the range of movement of the fixed block 10. The nozzle 11 is fixedly connected inside the fixed block 10 to spray the molybdenum top. The nozzle 11 is connected to the injection pipe 21 to deliver the spraying liquid. The end of the injection pipe 21 away from the nozzle 11 is connected to the spraying liquid to provide the spraying liquid. The side surface of the bracket 6 is fixedly connected to the lead screw motor 22 to provide power for the rotation of the lead screw 23. The output end of the lead screw motor 22 is fixedly connected to the lead screw 23 to transmit power. The lead screw 23 is rotatably connected to the inside of the guide rail 12 so that the lead screw 23 can rotate normally. The lead screw 23 is set inside the slider 13 to convert the rotational power of the lead screw 23 into the sliding force of the slider 13.

[0024] Guide rail 12 limits the movement range of slider 13. Guide rail 12 is set at the top of bracket 6 so that clamping component clamps molybdenum mandrel from above. Slider 13 is slidably connected inside guide rail 12, driving the lower clamping component to move and enabling slider 13 to move normally. Rotary motor 24 is fixedly connected inside slider 13 to provide power for the rotation of molybdenum mandrel. Turntable 25 is fixedly connected to the output end of rotary motor 24 to drive the lower clamping component to rotate. Clamping motor 14 is fixedly connected inside turntable 25 to provide power for the rotation of clamping disc 15. The output end of the clamping motor 14 is fixedly connected to the clamping plate 15 to transmit power. The clamping plate 15 has a spiral pattern 16 inside, which, together with the plate cover 18, converts the rotational power of the clamping plate 15 into the displacement power of the jaws 17. The jaws 17 are provided inside the spiral pattern 16, which press against the inner side wall of the molybdenum head to achieve the clamping operation of the molybdenum head. The jaws 17 are inverted "L" shape to increase the clamping area and increase the clamping stability. The plate cover 18 is rotatably connected to the surface of the clamping plate 15 to limit the displacement range of the jaws 17. The plate cover 18 is fixedly connected to the lower surface of the turntable 25.

[0025] Working principle: During the use of the device, the operator inverts the molybdenum mandrel and places it into the hopper 3. The screw motor 22 is started to rotate the screw 23. The rotational power of the screw 23 is converted into the power for the slider 13 to slide within the guide rail 12. This causes the slider 13 to move its lower clamping component, moving the gripper 17 in the clamping component directly above the hopper 3. The telescopic rod 2 is then activated to raise the hopper 3, moving the hollow part of the molybdenum mandrel towards the gripper 17. The clamping motor 14 is then started to rotate the clamping plate 15. Because the surface of the clamping plate 15 has outwardly spreading spiral patterns 16, the gripper 17, located inside the spiral patterns 16, is held in place by the plate cover 18 and cannot rotate with the clamping plate 15. It gradually moves towards the periphery of the clamping plate 15, causing the gripper 17 to press against the inner wall of the molybdenum mandrel, thus clamping the molybdenum mandrel. The telescopic rod 2 is then retracted, and the screw motor 2 is started again. 2. The clamping component moves the molybdenum top head towards the front of the nozzle 11, injecting spray liquid into the injection pipe 21, causing the spray liquid to spray out from the nozzle 11 to spray the molybdenum top head. The rotating motor 24 is started to drive the clamping component and the molybdenum top head to rotate and spray the molybdenum top head. The rotating motor 7 is started to rotate the rotating rod 8, which drives the connecting rod 9, which drives the fixed block 10 to form a crank-slider structure, realizing the up-and-down reciprocating movement of the fixed block 10. The fixed block 10 drives the internal nozzle 11 to move, thereby fully and evenly spraying the outer surface of the molybdenum top head. If there is excess spray liquid dripping from the molybdenum top head, it will fall into the liquid collection tank 4 directly below the molybdenum top head. The spray liquid that is not sprayed onto the surface of the molybdenum top head will be sprayed onto the surface of the baffle 5 directly in front of it, and then flow into the liquid collection tank 4 under the influence of gravity, thus facilitating the recycling and reuse of the spray liquid.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
