Description

Technical Field

[0001] This utility model relates to the field of ceramic tile production equipment technology, and more specifically, to a turning conveyor for a full-body marble ceramic tile production line. Background Technology

[0002] Through-body marble ceramic tiles are a new type of ceramic tile produced using high-temperature and high-pressure technology. These tiles have consistent color and texture throughout, resulting in excellent visual continuity. They also possess advantages such as high strength, wear resistance, easy cleaning, low water absorption, and environmental friendliness, making them suitable for various indoor spaces, especially damp areas, showcasing superior practicality and environmental performance. They are currently widely used in the building decoration industry.

[0003] The production of full-body marble tiles involves a series of processes, including forming, drying, firing, cooling, glazing, edge cutting, and polishing. Due to the large size of these tiles, typically 800mm x 800mm, the production line is quite long. To fully utilize the production space, the production line is usually arranged in an S-shape. When full-body marble tiles pass through the turning sections of the production line, centrifugal force can cause them to deviate from the center line, potentially even detaching from the line altogether, posing a safety hazard. Existing production lines typically reduce speed when full-body marble tiles pass through these turning sections, lowering the overall production speed and thus impacting efficiency.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 4As shown, this utility model discloses a turning conveyor for a full-body marble tile production line, including a frame 100, a U-shaped conveyor frame 200, and a fine-tuning mechanism 300. The two ends of the U-shaped conveyor frame 200 are rotatably connected to the frame 100 via a first rotating shaft 210 and a second rotating shaft 220, respectively. A plurality of guide rollers 230 are rotatably arranged on the U-shaped conveyor frame 200 along its conveying direction. The fine-tuning mechanism 300 is disposed between the frame 100 and the U-shaped conveyor frame 200 to adjust the tilt angle of the U-shaped conveyor frame 200. Specifically, in this embodiment, the turning conveyor for the full-body marble tile production line includes a frame 100, a U-shaped conveyor frame 200, and a fine-tuning mechanism 300. A plurality of guide rollers 230 are rotatably arranged on the U-shaped conveyor frame 200 along its conveying direction. The two ends of the U-shaped conveyor frame 200 are connected to a straight conveyor belt, allowing the product to move along the parallel straight conveyor belts via the U-shaped conveyor frame 200, thus making full use of space. In this embodiment, the product mainly refers to solid marble ceramic tiles or sheet-like or block-shaped building materials with smooth surfaces. Further, the two ends of the U-shaped conveyor frame 200 are rotatably connected to the frame 100 via a first rotating shaft 210 and a second rotating shaft 220, respectively; through this rotatable connection, the contact surface between the U-shaped conveyor frame 200 and the product can be tilted relative to the horizontal plane. Since the product generates centrifugal force when passing through a semi-circular path, the design of this mechanism allows the combined force of the product's gravity and the supporting force of the guide roller 230 to provide additional centripetal force to counteract some of the centrifugal force, ensuring that the product does not deviate significantly when passing through this device. The fine-tuning mechanism 300 can precisely adjust the tilt angle of the U-shaped conveyor frame 200 to meet different production line speeds. This mechanism's design reduces the impact of centrifugal force and decreases the product's dwell time at turns, thereby improving the overall efficiency of the production line.

[0033] In some embodiments of this utility model, the fine-tuning mechanism 300 includes an upper adjusting seat 310, a lower adjusting seat 320, an adjusting rod 330, and an adjusting sleeve 340. The upper adjusting seat 310 is fixedly connected to the U-shaped conveyor frame 200, and the lower adjusting seat 320 is fixedly connected to the frame 100. The adjusting sleeve 340 is rotatably connected to the upper adjusting seat 310, and the adjusting sleeve 340 is threadedly connected to the adjusting rod 330, with the lower end of the adjusting rod 330 abutting against the lower adjusting seat 320. Specifically, in this embodiment, the upper adjusting seat 310 is connected to the U-shaped conveyor frame 200 and serves to transmit the adjustment action to the U-shaped conveyor frame 200. The lower adjusting seat 320 is fixed to the frame 100, providing positioning and support to ensure the stability of the entire fine-tuning mechanism 300. The adjusting rod 330 is threadedly connected to the adjusting sleeve 340, with its lower end abutting against the lower adjusting seat 320. The adjusting sleeve 340 is rotatably connected to the upper adjusting seat 310 and forms a helical pair with the adjusting rod 330. Rotation changes their relative position, thereby adjusting the tilt angle of the U-shaped conveyor frame 200. During operation, when the tilt of the U-shaped conveyor frame 200 needs adjustment, the operator can manually or automatically drive the adjusting rod 330 to rotate. The threaded connection between the adjusting sleeve 340 and the adjusting rod 330 allows the adjusting rod 330 to move up and down. This movement is further transmitted to the upper adjusting seat 310, causing the U-shaped conveyor frame 200, which is fixed thereto, to rotate accordingly around the first rotating shaft 210 and the second rotating shaft 220. In this way, by controlling the rotation amplitude of the adjusting rod 330, the tilt angle of the U-shaped conveyor frame 200 can be adjusted to adapt to the needs of different product types and production line speeds.

[0034] In some embodiments of this utility model, a limiting baffle 341 is provided at the lower end of the adjusting sleeve 340. By providing the limiting baffle 341, in the event of thread failure or other malfunctions, the limiting baffle 341 can abut against the support structure provided on the lower adjusting seat 320 or the adjusting rod 330, thereby preventing damage to the U-shaped conveyor frame 200. In this embodiment, the support structure can be a shoulder 331 provided on the adjusting rod 330.

[0035] In some embodiments of this utility model, the fine-tuning mechanism 300 further includes an anti-loosening spring 350; the lower end of the adjusting rod 330 is provided with a shoulder 331; the anti-loosening spring 350 is sleeved on the adjusting rod 330, one end of the anti-loosening spring 350 abuts against the limiting baffle 341, and the other end of the anti-loosening spring 350 abuts against the shoulder 331. Through the design of this structure, the anti-loosening spring 350 can provide preload to prevent the adjusting rod 330 from rotating due to vibration generated during the movement of the equipment.

[0036] In some embodiments of this utility model, a handwheel 360 is provided at the upper end of the adjusting rod 330. By providing a handwheel 360 at the upper end of the adjusting rod 330, it is convenient for the operator to control the rotation of the adjusting rod 330.

[0037] In some embodiments of this utility model, the guide roller 230 includes a guide shaft core 231 and a bushing 232. The bushing 232 is sleeved on the guide shaft core 231, and a sprocket 233 is provided at one end of the guide shaft core 231. In this embodiment, a plurality of guide rollers 230 are rotatably arranged on the U-shaped conveyor frame 200 along its conveying direction, and all the guide rollers 230 are arranged in a fan-shaped structure on the U-shaped conveyor frame 200. A sprocket 233 is provided at one end of the guide roller 230. A servo motor drives a chain, thereby driving the sprocket 233 to rotate, and in turn driving the guide roller 230 to rotate. Through the design of this mechanism, the rotation of all the guide rollers 230 can be controlled, thereby providing power for the products passing through this device. The guide roller 230 adopts the design of a guide shaft core 231 and a bushing 232. After the bushing 232 wears out, only the bushing 232 needs to be replaced, which can reduce equipment maintenance costs.

[0038] In some embodiments of this utility model, the bushing 232 has a conical structure. In this embodiment, the bushing 232 is set as a conical structure. When the U-shaped conveyor frame 200 is in its initial state, that is, when the U-shaped conveyor frame 200 is in a horizontal position, the contact surface between the guide roller 230 and the product can form an inclined conveying surface. After normal operation for a period of time, the surface of the guide roller 230 will wear. By gradually controlling the tilt of the U-shaped conveyor frame 200 through the fine-tuning mechanism 300 to maintain the tilt angle of the conveying surface, the service life of the guide roller 230 can be extended.

[0039] In some embodiments of this invention, the bushing 232 is made of silicone. The silicone bushing 232 combines the elasticity of rubber with the toughness of plastic, allowing it to withstand significant deformation without permanent damage, making it suitable for withstanding continuous impacts and friction. Silicone maintains its physical properties in both high and low temperature environments, resisting both hardening and softening, making it suitable for continuous operation under extreme temperature conditions.

[0040] In some embodiments of this utility model, the bushing 232 is composed of a plurality of frustums 234, all of which are spaced apart on the guide shaft core 231 along the axial direction of the guide shaft core 231; the generatrices of all the frustums 234 are collinear. In this embodiment, each frustum 234 is arranged along the axial direction of the guide shaft core 231, with the larger end of their base area facing outward and the smaller end converging inward, together forming an approximately conical multi-step surface. The side generatrices of all the frustums 234 remain on the same oblique line, forming a multi-line supported conveying surface. The shape of the frustums 234 effectively disperses the contact points between the product and the bushing 232, thereby reducing wear caused by friction. When some frustums 234 are found to be severely damaged, the service life of the bushing 232 can be extended by replacing some of the frustums 234.

[0041] In some embodiments of this utility model, the bottom of the frame 100 is provided with anti-slip feet 110. By providing anti-slip feet 110, not only is there good anti-friction capability, but the anti-slip feet 110 can also be firmly fixed to the ground by anchor bolts.

[0042] 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.
