Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizers, and particularly relates to an automatic spraying device for a capsule release agent. Background Art

[0002] A capsule release agent is a liquid sprayed on the surface of a vulcanization capsule before vulcanizing a green tire to play a role in isolating the capsule from the green tire. Currently, water-based release agents are relatively commonly used; the usage method of the release agent affects the service life of both the tire and the capsule. Its usage methods mainly include brushing and spraying, and the spraying method is further divided into spraying on the capsule (external spraying) and spraying inside the green tire (internal spraying). The brushing method has a high labor intensity and low efficiency; internal spraying of the green tire is divided into mechanical spraying and manual spraying. Mechanical internal spraying is suitable for automated production lines. The advantages of internal spraying are that it does not pollute the mold and has high efficiency, while the disadvantages are that it has high requirements for the quality of the green tire. Therefore, the brushing method and the internal spraying method are generally not used in the production of all-steel radial truck tires. The external spraying method is generally adopted in the production of all-steel radial truck tires.

[0003] Currently, manual spraying has relatively harsh working environments (high temperature, vulcanization exhaust gas), potential safety hazards (mechanical extrusion, scalding, falling from height), low work efficiency, uneven spraying effects and the spraying effects cannot be uniformly supervised; it has an impact on the quality of vulcanized tires.

[0050] For the convenience of those skilled in the art to understand, the following further describes the present utility model in conjunction with the accompanying drawings.

[0051] Please refer to Figure 1 , which is an embodiment of an automatic spraying device for capsule release agent provided by the present utility model, used in the tire vulcanization process to spray the release agent on the outer wall of the capsule 5; it includes a moving platform 1, a first-direction displacement adjustment mechanism 2, a second-direction displacement adjustment mechanism 3, and a spraying mechanism 4. The moving platform 1, the first-direction displacement adjustment mechanism 2, and the second-direction displacement adjustment mechanism 3 cooperate coordinately to provide a suitable working position for the spraying mechanism 4.

[0052] Among them, the moving platform 1 carries the first-direction displacement adjustment mechanism 2, the second-direction displacement adjustment mechanism 3, and the spraying mechanism 4; the moving platform 1 includes a moving carrier, such as an AGV cart or an AGV handling robot, which can automatically move to the designated spraying position of the vulcanizer according to instructions; the moving carrier is a prior art, and this application has not made improvements to it, so no further description will be given here. Of course, different moving carriers can also be selected according to the site conditions. At the same time, in order to match the spraying operation requirements of the spraying mechanism 4, supporting components such as a release agent storage tank, a PLC controller, and a solenoid valve are also provided on the moving component, and the supporting components are also prior art, and this application has not made improvements.

[0053] After the moving platform 1 moves to the spraying position, the first-direction displacement adjustment mechanism 2 and the second-direction displacement adjustment mechanism 3 are used to adjust the working position of the spraying mechanism 4. As one of the implementation manners, the first-direction displacement adjustment mechanism 2 adjusts the position of the spraying mechanism 4 in the vertical direction, that is, the working height; to meet the spraying requirements of capsules at different heights; the second-direction displacement adjustment mechanism 3 adjusts the relative position of the spraying mechanism 4 and the capsule 5 in the horizontal direction, that is, the distance between the spraying mechanism 4 and the capsule 5, to meet different specifications of tire capsules and different models of vulcanizers.

[0054] Specifically, asFigure 2 As shown in Figure 2 , the second-direction displacement adjustment mechanism 3 includes a housing 31. An expansion and contraction rod 32 is arranged inside the housing 31, and the expansion and contraction rod 32 can adopt 2 or 3 movement strokes. The length of the expansion and contraction rod 32 extending out of the housing 31 can be adjusted automatically or manually. For example, the second-direction displacement adjustment mechanism 3 can adopt existing electric expansion and contraction rods, hydraulic expansion and contraction rods, etc. on the market. The spraying mechanism 4 is fixed on the expansion and contraction rod 32. Preferably, the spraying mechanism 4 is fixed at the end of the expansion and contraction rod 32.

[0055] The first-direction displacement adjustment mechanism 2 includes a vertical column 21, and the vertical column 21 is arranged vertically. A linear module capable of driving the second-direction displacement adjustment mechanism 3 to move up and down is arranged on the vertical column 21. The linear module can adopt a servo motor 22 and a lead screw 24. A linear guide rail 23 is arranged on the working surface of the vertical column 21, and a slider 33 is arranged on the outer wall of the housing 31. The slider 33 cooperates with the linear guide rail 23, allowing the housing 31 to move up and down relative to the vertical column 21 without slipping off the vertical column 21. The linear guide rail 23 can adopt existing guide rail structures such as dovetail guide rails. The servo motor 22 is installed on the vertical column 21. Preferably, the servo motor 22 is installed at the upper end or the lower end of the vertical column 21. The lead screw 24 is rotatably installed on the vertical column 21 and is in transmission connection with the servo motor 22. The transmission connection mode between the lead screw 24 and the servo motor 22 can be direct connection, that is, the output shaft of the servo motor 22 is directly connected to the lead screw 24 through a coupling; it can also be through transmission structures such as gear sets and belts for power transmission to realize the servo motor 22 driving the lead screw 24 to rotate. The slider 33 is threadedly connected to the lead screw 24. As the lead screw 24 rotates, the slider 33 drives the second-direction displacement adjustment mechanism 3 to rise or fall.

[0056] Correspondingly, displacement sensors and other detection elements can also be arranged on the vertical column 21 and the expansion and contraction rod 32 to accurately control the height of the spraying mechanism 4, the distance relative to the capsule 5, etc. This is prior art and will not be elaborated here.

[0057] The structure of the spraying mechanism 4 can refer to Figures 3 - 9 and includes a plurality of nozzles 46, a connecting seat, two groups of spraying arms 41, and a drive control component 42 for driving the spraying arms 41 to rotate. The connecting seat is used for fixedly connecting with the second-direction displacement adjustment mechanism 3 and at the same time meeting the installation requirements of the spraying arms 41 and the drive control component 42. The connecting seat includes two connecting plates 45. The two connecting plates 45 are parallel to each other and spaced apart, and an assembly space for the spraying arms 41 and the drive control component 42 is formed between the two connecting plates 45. The connecting plates 45 are fixedly connected to the expansion and contraction rod 32, and the connection method can be welding or detachable connection through connectors such as bolts and screws.

[0058] Refer to Figure 5, the spraying arm 41 includes a support rod 411 and a shield. It is set that the two end parts of the support rod 411 are respectively a free end and a connection end. The connection end of the support rod 411 is installed on the connection seat, and under the drive of the drive control assembly 42, the support rod 411 swings around its connection end to complete opening or closing; during spraying operations, when the two support rods 411 are in the closed state, they can surround the outside of the capsule 5 and maintain a set distance from the capsule 5; the specific value of the set distance can be selected according to actual operating needs.

[0059] Further, the support rod 411 is arc-shaped, preferably semi-circular arc-shaped.

[0060] The shield is installed on the support rod 411. The shape of the shield is preferably adapted to the shape of the support rod 411. The shield confines the spraying area of the release agent between the shield and the outer wall of the capsule 5.

[0061] The shield at least includes a main baffle part 414. The main baffle part 414 is fixed on the support rod 411. The connection method between the two can be welding, or the fixation connection between the two can be achieved by using connectors such as bolts and screws. During spraying, a release agent spraying space is formed between the main baffle part 414 and the outer wall of the capsule 5; after the two spraying arms 41 are closed, the release agent spraying space is similar to an annular shape.

[0062] Further, the main baffle part 414 is also connected with a first side baffle part 413 and a second side baffle part 415. The first side baffle part 413 and the second side baffle part 415 are respectively located on the opposite sides of the main baffle part 414, and form blockages at the two openings of the annular release agent spraying space respectively, restricting the spraying range in the up and down directions around the capsule 5 and preventing the release agent of the capsule from flying to the molds around below during spraying. Among them, the side of the first side baffle part 413 away from the main baffle part 414 is inclined and extends towards the outside of the release agent spraying space, which can appropriately expand the spraying range of the nozzle 46 in the up and down directions of the capsule 5.

[0063] The main baffle part 414, the first side baffle part 413 and the second side baffle part 415 together constitute a rigid shield part. The rigid shield part is processed from a rigid material and can be an integral structure; for example, it is bent from sheet metal. The sheet metal can be aluminum alloy, or a suitable material can be selected according to actual needs.

[0064] The side of the second side baffle part 415 away from the main baffle part 414 is connected with an auxiliary baffle part 412. The auxiliary baffle part 412 constitutes a soft shield part. The soft shield part is processed from soft and relatively strong materials such as rubber and polyurethane. The auxiliary baffle part 412 extends to the outer wall of the capsule 5 and can be in contact with the outer wall of the capsule 5.

[0065] There is a gap between the rigid shield part and the capsule 5, and the two do not come into direct contact. It is used to support and fix the protection range and can also prevent damage to the capsule 5 when the spraying arm 41 is clamped. The soft shield part is between the rigid shield part and the capsule 5, enabling the overall shield to better fit the irregular concave and convex shape of the capsule 5 after vacuum pumping, achieving a better protection effect. In addition, the second side baffle part 415 and the auxiliary baffle part 412 form a material receiving groove, which can catch the excess separating agent.

[0066] The nozzle 46 is fixed on the spraying arm 41, and multiple nozzles 46 are distributed in the length direction of the spraying arm 41. The spraying ranges of multiple nozzles 46 can cover the entire circumference of the capsule 5. Specifically, the nozzle 46 is fixedly installed on the shield or the support rod 411 and is connected to the separating agent storage tank through a pipeline. As one of the embodiments, as Figure 4 shown, the nozzle 46 is fixed on the main baffle part 414 and is arranged centripetally along the support rod 411. The spray outlet of the nozzle 46 is between the main baffle part 414 and the capsule 5. During spraying, the spraying range of the separating agent is limited within the separating agent spraying space. The nozzle 46 can be located on the upper side of the spraying arm 41 or on the lower side of the spraying arm 41, provided that the support rod 411 does not interfere with the spraying.

[0067] Furthermore, multiple nozzles 46 are evenly and spacedly distributed in the length extension direction of the support rod 411, and reference can be made to Figure 8 the distribution and spraying range of multiple nozzles 46 shown. The spraying angle of the nozzle 46 is preferably 120 degrees. With a large spraying angle, the coverage range is large, and there is an overlapping area between the coverage ranges of adjacent two nozzles 46, ensuring that the outer surface of the capsule 5 can be covered by the spraying range.

[0068] Referring to Figures 6 - 9 , the drive control assembly 42 includes a drive element 421, a first gear 423, and a second gear 424. The first gear 423 and the second gear 424 are respectively rotatably installed on the connecting seat through a rotating shaft 422. Two groups of spraying arms 41 are respectively corresponding to and fixedly connected to the first gear 423 and the second gear 424. When the first gear 423 and the second gear 424 rotate, they drive the corresponding spraying arms 41 to rotate synchronously. The drive element 421 serves as a power input component and can drive the first gear 423 and the second gear 424 to rotate.

[0069] As an implementation of the drive control component 42, both ends of the rotating shaft 422 are rotatably connected to the connecting plate 45 through bearings, that is, the rotating shaft 422 can rotate relative to the connecting plate 45. The first gear 423 and the second gear 424 are both fixed on the corresponding rotating shaft 422. The driving element 421 is a motor, and the output shaft of the motor is connected to the rotating shaft 422 corresponding to the first gear 423 through a coupling. The connecting end of the support rod 411 is fixedly connected to the rotating shaft 422 through the connecting plate 425; the connecting plate 425 can also be fixedly connected to the end face of the first gear 423 or the second gear 424, as long as it can be realized that the support rod 411 can rotate synchronously with the corresponding first gear 423 or second gear 424. The driving element 421 drives the first gear 423 to rotate, and the first gear 423 meshes with the second gear 424. In this way, the first gear 423 serves as a driving gear, and the second gear 424 serves as a driven gear, and the two rotate synchronously and in opposite directions. The two support rods 411 rotate around their respective connecting ends respectively, and the free ends of the two support rods 411 approach or separate from each other.

[0070] The first gear 423 and the second gear 424 are preferably exactly the same gears, which can not only achieve the same rotation amount of the two spraying arms 41, but also reduce the number of equipment parts and facilitate production. The driving element 421 is preferably a servo motor, and for capsules 5 with similar specifications / sizes, the opening and closing of the spraying device can be adaptively controlled by the servo motor without replacing the spraying device.

[0071] A number of distance measuring sensors are also provided on the spraying arm 41. Preferably, a first distance measuring sensor 44 is provided between the first gear 423 and the second gear 424. The first distance measuring sensor 44 is installed on the connecting plate 45 and is arranged radially along the support rod 411 for detecting the distance between the capsule 5 and the spraying arm 41 to avoid puncturing the capsule; a second distance measuring sensor 43 is provided at the free end of one group of spraying arms 41, which can detect the distance of the other group of spraying arms 41 to prevent clamping the capsule 5. A third distance measuring sensor (not shown in the figure) is provided on the spraying arm 41 or the connecting seat. The third distance measuring sensor is arranged axially along the support rod 411 for detecting the distance between the spraying arm 41 and its lower-side components, such as detecting the distance between the spraying arm 41 and the lower steel ring, to avoid collision with the lower steel ring during the spraying descent process.

[0072] Refer to Figure 10 During the spraying operation:

[0073] The moving platform 1 carries the first-direction displacement adjustment mechanism 2, the second-direction displacement adjustment mechanism 3, and the spraying mechanism 4 and moves together to the spraying position. During the movement, the two spraying arms 41 of the spraying mechanism 4 are in an open state;

[0074] After the mobile platform 1 arrives in place, control the first-direction displacement adjustment mechanism 2 to adjust the height of the spraying mechanism 4 and reach the set position; at the same time, control the second-direction displacement adjustment mechanism 3 to adjust the distance between the spraying mechanism 4 and the capsule 5; after detecting that the distance between the spraying mechanism and the capsule 5 meets the design requirements, control the two groups of spraying arms 41 to close;

[0075] After the first-direction displacement adjustment mechanism 2, the second-direction displacement adjustment mechanism 3, and the spraying arms 41 arrive in place, start the spraying operation; during spraying, while the spraying mechanism 4 is spraying, the first-direction displacement adjustment mechanism 2 is moving upward until the spraying of the entire height of the capsule is completed;

[0076] After the spraying is completed, end the spraying operation; control the spraying arms 41 to open, then control the second-direction displacement adjustment mechanism 3 to pull back the spraying mechanism 4, and at the same time control the first-direction displacement adjustment mechanism 2 to descend to the initial state, complete the entire spraying process, and control the mobile platform 1 to move to the next position for spraying operation.

[0077] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
