Description

Technical Field

[0001] This invention relates to the field of ceramic bathtub glazing positioning technology, specifically to a glazing positioning and clamping mechanism for ceramic bathtub processing. Background Technology

[0002] As an important product of sanitary ware, the quality of the surface glaze of ceramic bathtubs directly affects the product's aesthetics, corrosion resistance and service life. In the processing of ceramic bathtubs, glazing is a key process. By evenly spraying glaze onto the surface of the bathtub body, a smooth and dense glassy glaze layer is formed after high-temperature firing. The glaze spraying positioning and clamping mechanism for ceramic bathtubs is a special piece of equipment used in the production process of ceramic bathtubs. Its main purpose is to fix the ceramic bathtub in place so that it can be sprayed with glaze stably. In glazing operations, ceramic bathtubs are typically large, heavy, and have complex curved surfaces. Therefore, reliable positioning and clamping of the bathtub blank are required to ensure that the blank is stable and does not shift or shake during the glazing process. This ensures that the glaze layer is uniform in thickness and the coating is complete. Thus, the positioning and clamping mechanism is an important tooling equipment for achieving high-quality glazing operations. Existing bathtub glazing positioning and clamping mechanisms, such as the one disclosed in CN222309223U, provide a positioning clamp for bathtub glazing. This clamping and buffering mechanism can conveniently hold the bathtub during use, preventing damage to the bathtub due to excessive clamping force. At the same time, it can increase the contact area between the clamping parts and the surface of the bathtub, thereby increasing the stability of the bathtub positioning. However, when the above-mentioned existing technology is used, the glaze will drip onto the guide column and other corresponding components, which will cause the positioning fixture to become unstable after the glaze solidifies. In addition, it cannot collect the dripping glaze, thus failing to reduce the problem of glaze waste. Therefore, a glaze spraying positioning and clamping mechanism is needed for the processing of ceramic bathtubs to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a glaze spraying positioning and clamping mechanism for ceramic bathtub processing, in order to solve the problem mentioned in the background art that the existing glaze spraying positioning and clamping mechanism for bathtub processing cannot collect dripping glaze during use, and that the dripping glaze will solidify on the parts, making the parts unusable in the future.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A glaze spraying positioning and clamping mechanism for ceramic bathtub processing includes a base and a support seat coaxially connected to its upper surface by bearings. A mounting bracket coaxial with the support seat is fixed to the upper end of the support seat, and a collection tray is fixedly mounted to the upper end of the mounting bracket. A support plate coaxial with the support seat is provided on the inner surface of the collection tray. Support plates are provided on the support seat, and two support plates are symmetrically arranged on the support seat. A support frame is mounted on each support plate, and a driven plate is connected to the support frame by bearings. Two driven plates are mounted on each support frame, and two driven plates on the same support frame are connected by a synchronizing rod. A [missing information - likely a type of mounting bracket] is mounted at the head end of each driven plate. The mounting frame contains a pressure roller and a clamping mechanism for driving the driven plate to rotate. The clamping mechanism includes a strip-shaped groove that passes through the tail end of the driven plate. The rotation of the driven plate causes the pressure roller to press against the ceramic bathtub, facilitating glazing of the ceramic bathtub. A one-way rotation limiting mechanism is provided between the support frame and the driven plate. The one-way rotation limiting mechanism includes a mounting cover fixedly installed on the outside of the support frame. The one-way rotation limiting mechanism limits the rotation direction of the driven plate, ensuring that the ceramic bathtub is stably clamped during glazing. This prevents the pressure roller from failing to stably clamp the ceramic bathtub due to the reverse rotation of the driven plate, thus helping to ensure the stability of the ceramic bathtub during glazing.

[0005] Preferably, the inner surface of the recycling tray is inclined, and an opening is provided at the lowest point of the inner surface of the recycling tray.

[0006] Preferably, the driven plate is installed through the support frame via its shaft end bearing, and the axis of the synchronizing rod is collinear with the axis of the corresponding driven plate shaft end.

[0007] Preferably, the clamping mechanism further includes an oil collecting cylinder fixedly installed on the mounting frame, and the oil collecting cylinder is provided with an external connector. The rear ends of corresponding double-headed piston rods are movably inserted into the openings at both ends of the oil collecting cylinder, and the rear ends of the double-headed piston rods are connected to the inner side of the opening of the oil collecting cylinder through a seamless sliding connection.

[0008] Preferably, a drive frame is provided between the two driven plates on the same side, and the drive frame has a T-shaped structure. The two ends of the upper part of the drive frame slide through the strip-shaped through slots on the corresponding driven plates, and a driven rod coaxial with the double-ended piston rod is connected to the lower part of the drive frame. A piston seat is provided at the end of the driven rod, and the front end of the corresponding double-ended piston rod is movably inserted into the inner side of the opening of the piston seat. A spring is provided between the front end of the double-ended piston rod and the inner end of the piston seat.

[0009] Preferably, the unidirectional rotation limiting mechanism further includes a tapered limiting block provided at the shaft end of the driven plate, and the tapered limiting block is coaxially arranged with the shaft end of the driven plate. A piston block is seamlessly slidably connected inside the mounting cover on the corresponding side of the driven plate, and both the mounting cover and the piston block are coaxially arranged with the shaft end of the driven plate. The side of the piston block facing the tapered limiting block is connected to a limiting tapered sleeve through a one-way bearing.

[0010] Preferably, a guide groove coaxial with the piston block is provided on the other side, and a guide block is slidably connected in the guide groove, and the guide block is coaxially fixedly connected to the inner end of the mounting cover.

[0011] Preferably, the support frame and the corresponding support plate are integrally formed, and the structure formed by the support frame and the support plate is provided with a T-shaped liquid guiding channel.

[0012] Preferably, both ends of the upper part of the liquid guiding channel are connected to the corresponding mounting cover through a through hose, and the lower end of the liquid guiding channel is connected to the corresponding piston seat through a liquid guiding hose.

[0013] Preferably, the front end of the double-ended piston rod is connected to the inner side of the piston seat in a seamless sliding connection.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the glaze spraying positioning and clamping mechanism for ceramic bathtub processing can collect the dripping glaze during the glazing process of the ceramic bathtub, and can also prevent the glaze from dripping onto the important parts of the ceramic bathtub, thereby avoiding the problem that the important parts of the ceramic bathtub will become unusable later. In addition, it can also limit the clamping mechanism to ensure the stability of the clamping. 1. By setting the inner surface of the recycling tray to an inclined slope, it is easier to collect the dripping glaze from the opening on the recycling tray, thereby reducing glaze waste; 2. When clamping a ceramic bathtub, the pressure roller presses against the outside of the bathtub by rotating the driven plate. Therefore, when used with a recovery tray, it can prevent glaze from dripping onto the parts that drive the driven plate to rotate, thus allowing the clamping mechanism to be used continuously without the need for regular cleaning of glaze on the parts, thereby improving spraying efficiency. 3. After the bathtub is clamped and positioned, the driven plate can only rotate in one direction, which can effectively prevent it from rotating in the opposite direction. Therefore, it can avoid the clamping loosening due to external disturbances or changes in force, and ensure that the bathtub maintains a stable and reliable clamping state throughout the entire spraying process, which helps the spraying operation to be carried out continuously, orderly and stably.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides the following technical solution: Example 1: To address the problem in previous bathtub processing where glaze drips onto critical components during glazing, rendering them unusable after glaze solidification, a technical solution is provided: a glaze spraying positioning and clamping mechanism for ceramic bathtub processing, comprising a base 1 and a support 8 coaxially connected to its upper surface by bearings. A mounting bracket 9, coaxial with the support 8, is fixed to the upper end of the support 8, and a collection tray 2 is fixedly mounted to the upper end of the mounting bracket 9. A support plate 3, coaxial with the support 8, is provided on the inner surface of the collection tray 2. A support plate 15 is provided on the support 8. Two support plates 15 are symmetrically arranged on the support base 8. Each support plate 15 is equipped with a support frame 4, and a driven plate 5 is connected to the support frame 4 by a bearing. Two driven plates 5 are installed on each support frame 4, and the two driven plates 5 on the same support frame 4 are connected by a synchronizing rod 6. A pressure roller 17 is installed at the head end of the driven plate 5. A pressing mechanism for driving the driven plate 5 to rotate is installed inside the mounting frame 9. The pressing mechanism includes a strip-shaped through groove 20 that passes through the tail end of the driven plate 5. By rotating the driven plate 5, the pressure roller 17 presses the ceramic bathtub to facilitate the glazing of the ceramic bathtub.

[0019] In a preferred embodiment of the invention, the inner surface of the recycling tray 2 is inclined, and an opening is provided at the lowest point of the inner surface of the recycling tray 2.

[0020] In the above technical solution, the glaze that drips into the recycling pan 2 can flow along the inclined inner surface to the opening, which helps to collect the dripping glaze and reduces the waste of glaze.

[0021] In a preferred embodiment of the invention, the driven plate 5 is disposed through the support frame 4 via its shaft end bearing, and the axis of the synchronizing rod 6 is collinear with the axis of the corresponding driven plate 5 shaft end.

[0022] In the above technical solution, by setting the synchronizing rod 6, the two driven plates 5 on the same side can rotate synchronously, which helps to ensure that the pressure roller 17 on the same side can stably clamp the bathtub.

[0023] In a preferred embodiment of the invention, the clamping mechanism further includes an oil collecting cylinder 10 fixedly installed on the mounting bracket 9, and an external connector 11 is provided on the oil collecting cylinder 10. The rear ends of corresponding double-headed piston rods 12 are movably inserted into the openings at both ends of the oil collecting cylinder 10, and the rear ends of the double-headed piston rods 12 are connected to the inner side of the opening of the oil collecting cylinder 10 by a seamless sliding connection.

[0024] In the above technical solution, by connecting the external connector 11 to the oil pump, hydraulic oil can be delivered to the oil collection cylinder 10, or hydraulic oil in the oil collection cylinder 10 can be extracted, thereby achieving the purpose of moving the double-headed piston rod 12 on the oil collection cylinder 10.

[0025] In a preferred embodiment of the invention, a drive frame 7 is provided between two driven plates 5 on the same side, and the drive frame 7 has a T-shaped structure. The two ends of the upper part of the drive frame 7 slide through the strip-shaped through slots 20 on the corresponding driven plates 5, and a driven rod 13 coaxial with the double-headed piston rod 12 is connected to the lower part of the drive frame 7. A piston seat 18 is provided at the end of the driven rod 13, and the front end of the corresponding double-headed piston rod 12 is movably inserted into the inner side of the opening of the piston seat 18. A spring 19 is provided between the front end of the double-headed piston rod 12 and the inner end of the piston seat 18.

[0026] In the above technical solution, by moving the double-ended piston rod 12 outward relative to the oil collecting cylinder 10, the double-ended piston rod 12 can be gradually moved into the piston seat 18. When the double-ended piston rod 12 moves to a certain position, the piston seat 18 will move synchronously with the double-ended piston rod 12. After the bathtub is stably clamped, the piston seat 18 will no longer move, while the double-ended piston rod 12 will continue to move to its limit. Through this setting, the clamping mechanism can clamp bathtubs of different sizes.

[0027] according to Figures 1-4 When in use, connect the external oil pump to the external connector 11 to connect the oil collection cylinder 10 to the external hydraulic oil storage container. Before clamping the bathtub, place the bathtub on the support plate 3, and then drive the oil pump to inject the hydraulic oil in the hydraulic oil storage container into the oil collection cylinder 10. When the amount of hydraulic oil in the oil collecting cylinder 10 increases, it causes the two double-ended piston rods 12 on it to move away from each other, thereby causing the double-ended piston rods 12 to move toward the driven rod 13 connected to them. During the process, when the spring 19 is compressed to the extent of movement, the driven rod 13 will move synchronously with the double-ended piston rod 12; When the driven rod 13 moves, the drive frame 7 connected to it moves synchronously, thereby enabling the drive frame 7 to move on the strip groove 20; By moving the drive frame 7 on the strip groove 20, the driven plate 5 can be driven to rotate gradually, causing the pressure roller 17 to lift up and press tightly against the tilted side of the bathtub, thereby completing the clamping of the bathtub. After the bathtub is clamped, the double-ended piston rod 12 continues to move, which can compress the spring 19 to a shorter length, thereby ensuring that the pressure roller 17 clamps the bathtub. Subsequently, the bathtub is glazed manually or by machine. The glaze dripping from the bathtub will fall into the collection tray 2 and drain out from the opening along its inclined inner surface, thus making it convenient to collect the dripping glaze. In addition, since most of the important components of the bathtub are located below the recycling tray 2, the glaze will not drip onto the important components of the bathtub, thus avoiding the problem of the important components becoming unusable after the glaze solidifies. After ceramic glazing, the glaze is melted at high temperature to form a glassy coating. Then, it undergoes post-treatment through chemical polishing, which uses agents such as hydrofluoric acid or fluoroboric acid to perform controlled micro-corrosion on the glaze surface, preferentially dissolving the microscopic protrusions. This further reduces surface roughness and enhances gloss without damaging the glaze structure, thereby achieving a mirror-like smooth effect.

[0028] Example 2: To address the issue in Example 1 where the driven plate 5 might rotate in the opposite direction due to external force or other reasons after rotation, leading to loose clamping, the following technical solution is provided: A one-way rotation limiting mechanism is provided between the support frame 4 and the driven plate 5. This one-way rotation limiting mechanism includes a mounting cover 16 fixedly installed on the outside of the support frame 4. By limiting the rotation direction of the driven plate 5 through the one-way rotation limiting mechanism, the ceramic bathtub is stably clamped during glazing, preventing the pressure roller 17 from failing to stably clamp the ceramic bathtub due to the reverse rotation of the driven plate 5. This helps ensure the stability of the ceramic bathtub during glazing.

[0029] In a preferred embodiment of the invention, the unidirectional rotation limiting mechanism further includes a tapered limiting block 24 disposed at the shaft end of the driven plate 5, and the tapered limiting block 24 is coaxially disposed with the shaft end of the driven plate 5. A piston block 26 is seamlessly slidably connected inside the mounting cover 16 on the corresponding side of the driven plate 5, and both the mounting cover 16 and the piston block 26 are coaxially disposed with the shaft end of the driven plate 5. The side of the piston block 26 facing the tapered limiting block 24 is connected to a limiting tapered sleeve 25 through a one-way bearing.

[0030] In the above technical solution, the cooperation between the conical limiting block 24 and the limiting conical sleeve 25 enables the rough surfaces of the two to contact each other, and the rotation direction of the driven plate 5 can be restricted by a one-way bearing. In other words, it can ensure that the bathtub cannot be loosened after being clamped.

[0031] In a preferred embodiment of the invention, a guide groove 27 coaxial with the piston block 26 is provided on the other side, and a guide block 21 is slidably connected in the guide groove 27. The guide block 21 is coaxially fixedly connected to the inner end of the mounting cover 16.

[0032] In the above technical solution, the piston block 26 can be limited by the guide block 21 moving in the guide groove 27, so as to ensure that it moves stably along the axis of the driven plate 5 within the mounting cover 16.

[0033] In a preferred embodiment of the invention, the support frame 4 and the corresponding support plate 15 are integrally formed, and a T-shaped liquid guiding channel 22 is provided in the structure formed by the support frame 4 and the support plate 15.

[0034] In the above technical solution, by setting a T-shaped liquid guiding channel 22, it is convenient to install the cover 16 and the piston seat 18 to pass through, thereby facilitating the flow of hydraulic oil between the two.

[0035] In a preferred embodiment of the invention, both ends of the upper part of the liquid guiding channel 22 are connected to the corresponding mounting cover 16 through the through hose 23, and the lower end of the liquid guiding channel 22 is connected to the corresponding piston seat 18 through the liquid guiding hose 14.

[0036] In the above technical solution, the mounting cover 16 and the piston seat 18 can be connected by the through hose 23 and the liquid guiding hose 14.

[0037] In a preferred embodiment of the invention, the front end of the double-ended piston rod 12 is connected to the inner side of the piston seat 18 in a seamless sliding connection.

[0038] In the above technical solution, when the double-ended piston rod 12 moves relative to the piston seat 18, the hydraulic oil can flow between the mounting cover 16 and the piston seat 18, which facilitates the stable and tight compression of the conical limiting block 24 and the limiting conical sleeve 25 after the bathtub is clamped. In other words, the driven plate 5 can only rotate in one direction, thereby ensuring the stability of clamping the bathtub.

[0039] according to Figures 5-8 During the process of the double-ended piston rod 12 moving into the piston seat 18, the hydraulic oil in the piston seat 18 can enter the mounting cover 16 through the fluid guide hose 14, the fluid guide channel 22 and the through hose 23. This allows the piston block 26 inside the mounting cover 16 to stably move closer to the conical limiting block 24 under the limiting action of the guide groove 27 and the guide block 21; This causes the conical limiting block 24 to fit tightly with the corresponding limiting conical sleeve 25. Since the contact surface between the two is a rough surface with a large coefficient of friction, and the limiting conical sleeve 25 is connected to the piston block 26 through a one-way bearing, the conical limiting block 24 can be prevented from rotating in the opposite direction. In other words, the driven plate 5 can be prevented from rotating in the opposite direction, thereby ensuring the stability of the pressure roller 17 clamping the bathtub. In addition, as the drive frame 7 slides within the strip groove 20, the driven plate 5 and the support frame 4 gradually form a lever structure, ensuring the clamping force of the pressure roller 17 on the bathtub.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
