Description

Technical Field

[0001] This utility model relates to the technical field of toy car production equipment, specifically a cleaning device for the production of children's toy car tires. Background Technology

[0002] Children's toy cars are generally composed of a body, chassis and tires. To improve the anti-slip ability of toy cars, rubber tires are usually used. However, it has been found in the production process that the surface of rubber tires is very easy to get dusty. In order to ensure the cleanliness of rubber tires when they leave the factory, it is necessary to use a cleaning device to clean the rubber tires.

[0003] A Chinese patent (publication number: CN220049124U) discloses a cleaning device for the production of children's toy car tires, including a cleaning box. A door is hinged to the front of the cleaning box, and a controller is fixedly installed on the front of the door. A rinsing mechanism is fixedly installed on the upper surface of the cleaning box. The cleaning box includes a body, and a power groove is formed at the bottom of the body. A motor is fixedly installed at the bottom of the inner cavity of the power groove. This cleaning device for the production of children's toy car tires uses a rinsing mechanism to spray water. Starting the motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate. The driven wheel drives a rotating rod and the tire body to rotate. When the tire body rotates, a brush cleans the surface of the tire body. The friction between the brush and the tire body cleans the grooves on the tire body surface, resulting in a comprehensive cleaning of the tire body, improving the cleaning effect of the equipment and increasing the cleanliness of the tire body.

[0004] In use, the aforementioned cleaning device cleans tires by placing them on a rotating rod, which then rotates in conjunction with a cleaning brush. While it can clean tires, the lack of an adjustment mechanism on the rotating rod limits its applicability to a single tire model.

[0005] To address this issue, we designed a cleaning device for the production of children's toy car tires. Utility Model Content

[0006] The purpose of this invention is to provide a cleaning device for the production of children's toy car tires, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a cleaning device for the production of children's toy car tires, including a cleaning box, an installation cylinder rotatably connected inside the cleaning box, a first bidirectional lead screw rotatably connected inside the installation cylinder, two symmetrical first nuts threaded onto the first bidirectional lead screw, at least two symmetrical connecting plates rotatably connected to the first nuts, a contact plate rotatably connected to the other end of the connecting plate, a first servo motor for driving the first bidirectional lead screw to rotate connected to the installation cylinder, and two symmetrical cleaning plates slidably arranged inside the cleaning box.

[0008] Furthermore, a connecting frame is connected to the top of the mounting cylinder, and a second servo motor is connected to the top of the cleaning tank. The second servo motor is connected to the side of the connecting frame away from the mounting cylinder via a coupling.

[0009] Furthermore, a second bidirectional lead screw is rotatably connected inside the cleaning tank, and a second nut is connected to the bottom of the cleaning plate, with the second nut threaded onto the second bidirectional lead screw.

[0010] Furthermore, a connecting frame is connected to the inner bottom wall of the cleaning tank, the second bidirectional lead screw is rotatably connected to the connecting frame, the mounting cylinder is rotatably connected to the top of the connecting frame, the end of the first bidirectional lead screw extends into the connecting frame, a first bevel gear is connected to the second bidirectional lead screw, a second bevel gear is meshed with the first bevel gear, a fixed cylinder is connected to the second bevel gear, a telescopic rod is slidably connected to the fixed cylinder, an insertion slot for inserting the telescopic rod is opened at the end of the first bidirectional lead screw, and a limiting screw for limiting the telescopic rod is inserted into the bottom of the first bidirectional lead screw.

[0011] Furthermore, a guide rod is connected inside the cleaning tank, and the second nut is slidably connected inside the guide rod. The second nut has a sliding opening that matches the guide rod.

[0012] Furthermore, the mounting cylinder is provided with a guide groove, which is used to guide the first nut.

[0013] Furthermore, two symmetrical spray pipes are connected to the inner top wall of the cleaning tank, and multiple nozzles are connected to the spray pipes.

[0014] Furthermore, a water storage tank is connected to the rear side of the cleaning tank, and a water pump is connected to the water storage tank. The water outlet of the water pump is connected to the water inlet of the spray pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The first servo motor drives the first bidirectional lead screw, which in turn moves the two first nuts in opposite directions, thereby causing the contact plate to adhere to the inner wall of the tire and complete the fixation. This setting can be flexibly adjusted according to the inner diameter of the tire, ensuring a stable installation for both small and large children's toy car tires.

[0017] 2. During the process of fixing the tire with the first bidirectional lead screw, the second bidirectional lead screw is driven simultaneously, allowing the cleaning plate to automatically adapt to the tire size. No manual adjustment of the cleaning position is required. This feature achieves synchronized adjustment of the cleaning plate's position via the second bidirectional lead screw, realizing the linkage adjustment between the fixing and cleaning components. Compared to traditional single-size cleaning devices, this feature significantly expands the adaptability range. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figure 1-5This utility model provides a technical solution: a cleaning device for the production of children's toy car tires, including a cleaning tank 1, an installation cylinder 2 rotatably connected inside the cleaning tank 1, a first bidirectional lead screw 3 rotatably connected inside the installation cylinder 2, two symmetrical first nuts 4 threaded onto the first bidirectional lead screw 3, at least two symmetrical connecting plates 5 rotatably connected to the first nuts 4, a contact plate 6 rotatably connected to the other end of the connecting plate 5, a first servo motor 7 connected to the installation cylinder 2 to drive the first bidirectional lead screw 3 to rotate, and two symmetrical cleaning plates 10 slidably arranged inside the cleaning tank 1.

[0026] In practice, the toy car tire to be cleaned is placed inside the mounting cylinder 2, and the first servo motor 7 is started, driving the first bidirectional lead screw 3 to rotate. Since the first bidirectional lead screw 3 is threadedly connected to two first nuts 4, as the first bidirectional lead screw 3 rotates, the two first nuts 4 move in opposite directions along the lead screw. The first nuts 4 are rotatably connected to the contact plate 6 via the connecting plate 5. When the first nuts 4 move, they drive the connecting plate 5 and the contact plate 6 to move until the contact plate 6 is tightly fitted against the inner wall of the tire, fixing the tire in place. At this point, the cleaning plate 10 can clean the tire surface. This setting can adaptively adjust according to the inner diameter of the tire, improving the adaptability of the device.

[0027] See Figure 1-5 The top of the mounting cylinder 2 is connected to a connecting frame 8, and the top of the cleaning tank 1 is connected to a second servo motor 9. The second servo motor 9 is connected to the side of the connecting frame 8 away from the mounting cylinder 2 via a coupling.

[0028] In practice, the second servo motor 9 can drive the connecting frame 8 to rotate, and then the connecting frame 8 can drive the mounting cylinder 2 and the tires mounted on the mounting cylinder 2 to rotate, further improving the cleaning effect.

[0029] See Figure 1-5 A second bidirectional lead screw 11 is rotatably connected inside the cleaning tank 1, and a second nut 21 is connected to the bottom of the cleaning plate 10. The second nut 21 is threaded onto the second bidirectional lead screw 11.

[0030] In practice, rotating the second bidirectional lead screw 11 can drive the second nut 21 to move in opposite directions or relative to each other, thereby adapting to tires of different sizes.

[0031] See Figure 1-5A connecting frame 12 is connected to the inner bottom wall of the cleaning tank 1. A second bidirectional lead screw 11 is rotatably connected to the connecting frame 12. An mounting cylinder 2 is rotatably connected to the top of the connecting frame 12. The end of the first bidirectional lead screw 3 extends into the connecting frame 12. A first bevel gear 16 is connected to the second bidirectional lead screw 11. A second bevel gear 17 is meshed with the first bevel gear 16. A fixed cylinder 13 is connected to the second bevel gear 17. A telescopic rod 14 is slidably connected to the fixed cylinder 13. An insertion slot for the telescopic rod 14 is opened at the end of the first bidirectional lead screw 3. A limiting screw 15 for limiting the telescopic rod 14 is inserted into the bottom of the first bidirectional lead screw 3.

[0032] In practice, when the first bidirectional lead screw 3 rotates, the telescopic rod 14, which is inserted into its end slot, rotates accordingly. The telescopic rod 14 drives the second bevel gear 17 to rotate, and the second bevel gear 17 meshes with the first bevel gear 16, thereby driving the first bevel gear 16 and the second bidirectional lead screw 11 to rotate. In this way, while adjusting the contact plate 6 to fix the tire, the cleaning plate 10 can also be adjusted accordingly.

[0033] See Figure 1-5 The cleaning tank 1 is connected to a guide rod 18, and a second nut 21 is slidably connected inside the guide rod 18. The second nut 21 has a sliding opening that matches the guide rod 18.

[0034] In practice, when the second nut 21 moves linearly under the drive of the second bidirectional lead screw 11, the guide rod 18 guides and limits the second nut 21, ensuring that the second nut 21 can only move along the direction of the guide rod 18.

[0035] See Figure 1-5 The mounting cylinder 2 is provided with a guide groove 20, which is used to guide the first nut 4.

[0036] In practice, when the first nut 4 moves under the drive of the first bidirectional lead screw 3, the guide groove 20 guides the first nut 4 to prevent the first nut 4 from rotating or deviating during the movement.

[0037] See Figure 1-5 Two symmetrical spray pipes 19 are connected to the inner top wall of the cleaning tank 1, and multiple nozzles are connected to the spray pipes 19.

[0038] In practice, multiple nozzles on the water spray pipe 19 spray water to form a water flow, pre-rinsing the tire surface. During the tire cleaning process by the cleaning plate 10, the spray pipe 19 continuously sprays water to moisten the tire surface and wash away dirt, assisting the cleaning plate 10 in completing the cleaning work better.

[0039] See Figure 1-5A water storage tank is connected to the rear side of the cleaning tank 1, and a water pump is connected to the water storage tank. The water outlet of the water pump is connected to the water inlet of the spray pipe 19.

[0040] In practice, the water pump is connected to the water storage tank. When the water pump starts, it draws water from the water storage tank and transports it through the pipeline to the spray pipe 19 to provide a water source for the spray pipe 19.

[0041] Working principle: The first servo motor 7 is started, which drives the first bidirectional lead screw 3 to rotate. Since the first bidirectional lead screw 3 is threadedly connected to the two first nuts 4, as the lead screw rotates, the two first nuts 4 move in opposite directions along the lead screw. The first nuts 4 are rotatably connected to the abutment plate 6 through the connecting plate 5. The movement of the first nuts 4 drives the connecting plate 5 and the abutment plate 6 to move until the abutment plate 6 is tightly fitted against the inner wall of the tire, thus completing the fixation of the tire.

[0042] During this process, the telescopic rod 14 can be inserted into the end of the first bidirectional lead screw 3 and then fixed using the limiting screw 15. Therefore, while the first bidirectional lead screw 3 rotates to fix the tire, the telescopic rod 14 inserted into its end also rotates. The telescopic rod 14 drives the second bevel gear 17 to rotate, and the second bevel gear 17 meshes with the first bevel gear 16, thereby driving the first bevel gear 16 and the second bidirectional lead screw 11 to rotate, causing the cleaning plate 10 to move in opposite directions or relative to each other, thereby adjusting the position of the cleaning plate 10 to adapt to the cleaning needs of tires of different sizes, realizing the linkage between tire fixing and cleaning plate 10 position adjustment.

[0043] The second servo motor 9 starts and drives the connecting frame 8 to rotate via the coupling. The connecting frame 8 then drives the mounting cylinder 2 and the tire fixed inside the mounting cylinder 2 to rotate. At the same time, the spray pipe 19 on the top wall of the cleaning tank 1 draws water from the water tank under the action of the water pump and sprays water through multiple nozzles to pre-wash the tire surface. During the cleaning process, water is continuously sprayed to moisten the tire surface and wash away dirt.
