Description

Technical Field

[0001] The invention relates to the technical field of rust-proof spraying, in particular to a surface rust-proof treatment device for pulley production and processing. Background Art

[0002] The pulley is a wheel-shaped part that belongs to the hub type. It is used to install the belt. If the pulley is not treated with rust prevention, rust will make the pulley surface rough and uneven, and the friction between the pulley and the belt will be unevenly distributed. When the friction is insufficient, the belt is prone to slipping, resulting in unstable power transmission, fluctuations in the running speed of the equipment, and inability to maintain a stable working state, reducing production efficiency and shortening the service life of the belt; Therefore, it is necessary to spray rust-proof agent during the production process of pulleys of corresponding specifications. After spraying, the rust-proof component forms a protective film on the metal surface, which dries quickly and has good film-forming properties. It is suitable for short-term or long-term rust prevention of various metal products. In the related art, the pulley is often treated with immersion for rust prevention, which easily leads to waste of resources in the process. When spraying for rust prevention, the traditional spraying device can only spray one side of the pulley. After the single-side spraying is completed, the reverse side needs to be treated, which is time-consuming and labor-intensive. The working environment is completely open and easy to pollute the environment. In addition, the support structure is not convenient to adjust the position, which affects the loading and unloading rates of the material. Summary of the invention

The first motor 3 drives the first screw 4 to rotate under the support of the base 1, and the first slider 5 is slidably connected with the first slide groove. Driven by the first screw 4, the first slider 5 drives the arc frame 6 to make a linear motion and move toward the pulley. After the arc frame 6 moves to the specified position, that is, at this time, the first output head 8 is located above the vertically placed pulley, and the two groups of second output heads 9 are located on the left and right sides of the pulley. The two groups of second output heads 9 are inclined toward the middle part of the pulley. The liquid supply component 2 is started. The liquid supply component 2 includes a liquid supply box and a liquid supply pump. The mounting frame 7 is fixed on the arc frame 6 to stably support several groups of liquid supply boxes. The liquid supply pump delivers the rust inhibitor in the liquid supply box to the corresponding output head, and the output head sprays the rust inhibitor on the corresponding position of the pulley.

[0019] In actual use, it is necessary to adjust the spacing between the various components in the support member to facilitate loading and unloading. To this end, the support member includes a feed member, an active rotating member and a driven rotating member. The feed member includes a side plate 10, a second slider 11, a first worm wheel 12, a first worm 13 and a second screw 14. Second slide grooves are symmetrically arranged on the left and right sides above the base 1. A first active cavity is arranged between the two groups of the second slide grooves. The first screw 4 passes through the first active cavity and is connected to the first worm 13. The first active cavity is also provided with a first worm wheel 12 meshing with the first worm 13. The first The left and right sides of the center of the worm wheel 12 are provided with a second screw 14 that passes through the second slide slot. The second slider 11 is T-shaped. The lower part of the second slider 11 extends into the second slide slot and is threadedly connected with the second screw 14. The upper part of the side plate 10 is disc-shaped, and the lower part is rectangular. The lower part of the side plate 10 is connected to one end of the second slider 11. The two groups of side plates 10 are respectively provided with active rotating parts and driven rotating parts that drive the sprayed objects. The first screw 4 passes through the first active cavity and is connected to the first worm 13. When the first motor 3 rotates, it will also drive the first worm 13 to rotate through the first screw 4. The first worm wheel 12 in the first active cavity is meshed with the first worm 13, and the rotation of the first worm 13 drives the first worm wheel 12 to rotate. The second screws 14 on the left and right sides of the center of the first worm gear 12 rotate with the first worm gear 12. Since the lower part of the second slider 11 is threadedly connected to the second screw 14 and extends into the second slide groove, the rotation of the second screw 14 causes the second slider 11 to move in the second slide groove, thereby driving the side plate 10 to move. When the arc frame 6 moves toward the sprayed material (pulley), the distance between the two sets of side plates 10 becomes smaller. The active rotating member is used to drive the sprayed material to rotate, and the driven rotating member is used to support and limit the sprayed material, so as to ensure the stability of the center positioning of the material when it rotates.

[0020] In this embodiment, the active rotating member includes a second motor 15, a support shaft 16 and a first retaining ring 17. The output end of the second motor 15 passes through a group of the side plates 10 and is connected to the support shaft 16. The support shaft 16 is also sleeved with a first retaining ring 17. The driven rotating member includes a bearing 18, a second retaining ring 19, a support ring 20 and a connecting rod 21. A rotation groove is provided on another group of the side plates 10. The outer ring of the bearing 18 is connected to the inner wall of the rotation groove. The inner ring of the bearing 18 is provided with the support ring 20. The support shaft 16 can pass through the second retaining ring 19. The second retaining ring 19 is connected to the support ring 20 through the connecting rod 21. At first, when the distance between the two groups of side plates 10 is large, the support shaft 16 and the second retaining ring 19 are misaligned. At this time, The material is loaded onto the shaft 16, and the sprayed material is attached to the first baffle ring 17. As the spacing between the two groups of side plates 10 becomes smaller, the material is clamped between the first baffle ring 17 and the second baffle ring 19. The second motor 15 on one group of side plates 10 is started, and the second motor 15 drives the support shaft 16 and the first baffle ring 17 to rotate. Through friction, the second baffle ring 19 rotates accordingly. The second baffle ring 19 is connected to the support ring 20 on the other group of side plates 10 through a connecting rod 21, and the support ring 20 is connected to the other group of side plates 10 through a bearing 18, which is convenient for stable rotation. The first baffle ring 17 and the second baffle ring 19 are both provided with friction rings 22 near the sprayed object, further ensuring the stability of the rotation of the material after being clamped. In this embodiment, the first motor 3 and the second motor 15 both adopt precisely controlled servo motors.

[0021] In actual use, after the first output head 8 and the second output head 9 are sprayed, if part of the waste liquid is directly spilled, it is easy to cause waste of resources and even pollute the environment. For this reason, the left and right sides of the arc frame 6 are provided with inner grooves adapted to the side panels 10, and the front of the arc frame 6 is also provided with a gathering groove, and a collecting groove with an upper opening is also provided above the lower part of the gathering groove, and a filter frame 23 is also provided on the upper part of the collecting groove, and a drainage pipe 24 that passes through the collection groove is also provided on the lower part of the front of the arc frame 6, and a switch valve 25 is provided on the drainage pipe 24. The two groups of side panels 10 and the arc frame 6 are connected. The frame 6 encloses a spraying chamber. When the object to be sprayed is stably clamped, the arc frame 6 no longer feeds forward, and the two sets of side panels 10 stably fit the inner groove of the arc frame 6 to enclose a spraying chamber. At this time, the spraying operation is carried out. Due to the shape of the inner wall of the arc frame 6 and the angles of the first output head 8 and the second output head 9, the waste liquid will be collected into the collection tank and finally fall into the collection tank after passing through the filter frame 23. According to needs, the switch valve 25 can be opened, and the waste liquid is transported by the drain pipe 24. After being filtered again, it is reasonably utilized to reduce the waste of resources. At the same time, it is convenient to collect and treat the waste liquid in a centralized manner to avoid its direct exposure to the external environment.

[0022] During actual use, if a closing plate is provided on the side of the side plate 10 away from the arc frame 6, at this time, the protruding closing plate will reduce the material loading and unloading space as the arc frame 6 closes the spray chamber. For this reason, the base 1 is also provided with a closing component for closing the opening of the spray chamber, and the closing component includes a second worm 26, a second worm wheel 27, a third slider 28, a third screw 29 and an arc plate 30. A third slide groove is also provided on the left and right sides of the base 1. The second slide groove is provided between the third slide groove and the first slide groove. A second active cavity is also provided between the two groups of the third slide grooves. The second active cavity is provided with a second worm 26 connected to the first worm 13. The third slider 28 is provided with a third screw 29 and a third screw 29 is provided with a third screw 29. A third screw 29 is also rotatably arranged in the groove, the third screw 29 passes through the second active cavity and is connected to the center of the second worm gear 27, the second worm gear 27 is meshed with the second worm 26, the third slider 28 is T-shaped, the lower part of the third slider 28 extends into the third chute and is threadedly connected to the third screw 29, a fixed plate 31 is also arranged on one side of the arc plate 30, the fixed plate 31 is arranged on the third slider 28, two sets of fitted arc plates 30 close the front opening of the spraying cavity, the pitch of the third screw 29 is greater than the pitch of the second screw 14, and when the first worm 13 rotates, it will drive the second worm 26 connected thereto to rotate in the second active cavity. The second worm gear 27 in the second active cavity is meshed with the second worm 26, and the rotation of the second worm 26 drives the second worm gear 27 to rotate. The third screw 29 passes through the second active cavity and is connected to the center of the second worm gear 27, and the rotation of the second worm gear 27 causes the third screw 29 to rotate in the third chute. Since the lower part of the third slider 28 is threadedly connected to the third screw 29 and extends into the third slide groove, the rotation of the third screw 29 causes the third slider 28 to move in the third slide groove, thereby driving the arc plate 30 to move. The two groups of arc plates 30 fit together to close the front opening of the spray chamber. The first worm gear 12 and the second worm gear 27 have the same specifications, and the first worm 13 and the second worm 26 have the same specifications. Initially, the spacing between the two groups of third sliders 28 is greater than the spacing between the two groups of second sliders 11. When the two groups of side plates 10 fit into the inner groove, the two groups of closing plates close the spray chamber.

[0023] During actual use, the second slider 11 is further provided with a first reinforcing rib 32 connected to the side plate 10, the first reinforcing rib 32 is arranged in two groups symmetrically, the second motor 15 is arranged between the corresponding two groups of the first reinforcing rib 32, and the third slider 28 is further provided with a second reinforcing rib 33 connected to the fixed plate 31, the first reinforcing rib 32 ensures the connection cavity between the second slider 11 and the side plate 10, and the second reinforcing rib 33 ensures the connection strength between the third slider 28 and the fixed plate 31.

[0024] In this embodiment, the bottom wall of the base 1 is provided with a through hole penetrating the bottom walls of the first slide groove, the second slide groove and the third slide groove, so as to facilitate cleaning and ensure the stability of equipment operation.

[0025] In actual use, the top wall of the arc frame 6 is also provided with a ventilation valve 34 and a ventilator 35 that penetrate the spray chamber. The ventilation valve 34 can be a pressure valve. When spraying, the first output head 8 and the second output head 9 are both arranged below the input end of the ventilator 35. The ventilator 35 is started, and the ventilator 35 can discharge the gas in the spray chamber and can be connected to the air purification device through a pipeline. The ventilation valve 34 ensures the balance between the spray chamber and the external pressure, and ensures the stability of the equipment operation. It should be noted that the first output head 8 and the second output head 9 will not cause motion interference with the pulley during the feeding process of the object.
