Description

Technical Field

[0001] The utility model belongs to the technical field of stone conveying, and particularly relates to a stone quantitative conveying and paving mechanism. Background Art

[0002] In the existing technology, in the stone processing industry, realizing the continuous and uniform distribution of stones is the key to improving production efficiency and product quality. However, there are many problems with traditional stone conveying and paving methods. First of all, stones cannot be effectively conveyed and paved, resulting in frequent interruptions in the production process. This not only reduces production efficiency but also fails to achieve the continuous and uniform distribution of stones. Secondly, it is difficult to control the feeding speed and distribution of stones, often resulting in uneven accumulation or scattering of stones on the conveyor belt. This situation not only wastes raw materials but also increases the workload of cleaning and maintenance. In addition, due to the lack of automatic control, a large amount of manual intervention is required, which is not only inefficient but also prone to introducing human errors, affecting the consistency of product quality. These problems seriously restrict the development of the stone processing industry and the improvement of product quality.

[0003] In the process of stone processing, accurately controlling the feeding amount is crucial for ensuring product quality. However, in the existing technology, the feeding of stones is often difficult to accurately control, which leads to uneven distribution of stones on the conveyor belt, directly affecting the subsequent processing quality and increasing the rejection rate and rework rate. More importantly, existing equipment generally lacks flexibility and adaptability, and it is difficult for operators to adjust the feeding amount according to the characteristics of different stones (such as size, weight, shape) and production requirements (such as thickness requirements, surface treatment). This rigid design greatly limits the application range of the equipment and cannot meet the market demand for diversified and personalized stone products. At the same time, it also increases the frequency of equipment replacement and debugging, raising the production cost.

[0004] In the process of stone paving, flexibly adjusting the equipment parameters according to different types and sizes of stones is the key to ensuring product quality. However, in the existing technology, operators often cannot accurately adjust the position of key components (such as baffles), which means the equipment cannot adapt to different types and sizes of stones. For example, when dealing with stones of larger sizes or irregular shapes, fixed-position baffles may not provide appropriate guidance, resulting in uneven distribution or accumulation of stones. Similarly, for smaller or thinner stones, existing equipment may not provide fine enough control, affecting the paving effect. This limitation not only reduces production efficiency but also may prevent certain types of stones from achieving an ideal paving effect, restricting the enterprise's ability to accept diversified orders and affecting market competitiveness.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0014] Preferably, a slot is provided on the inner wall of the socket, and a clip is provided on the outer wall of the support rod, and the clip fits into the slot. This design ensures that the support rod will not rotate or deflect during adjustment, thereby ensuring the accuracy of the adjustment.

[0015] Preferably, a slide bar is installed on the inner side of the bracket, and the slide bar is slidably connected to the transmission block. This design reduces the shaking and offset of the transmission block during movement, ensuring the linearity and consistency of the adjustment action.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The motor of the utility model drives the transmission roller to rotate, driving the conveyor belt to run, realizing continuous conveying of stone.

[0028] Embodiment

[0029] Refer to the appendix Figures 1-5, a stone quantitative conveying and leveling mechanism, including a support 1, on which a conveying and leveling mechanism is provided. The conveying and leveling mechanism includes a motor 2, a driving roller 3, a conveyor belt 4, a feeding hopper 5 and a baffle 6. The motor 2 is installed on the side wall of the support 1. There are two groups of driving rollers 3 rotatably installed on the support 1 and connected to the output end of the motor 2. The conveyor belt 4 is arranged on the outer walls of the two groups of driving rollers 3. The feeding hopper 5 is installed on the support 18, and the baffle 6 is arranged on the feeding hopper 8. A quantitative mechanism is provided on the feeding hopper 8. The quantitative mechanism includes a quantitative box 7, a feeding hopper 8, a baffle 9, a cylinder 10, a hinge block 11 and a hinge rod 12. The quantitative box 7 is installed at the top of the feeding hopper 8, and the feeding hopper 8 is installed inside the quantitative box 7. There are two groups of baffle plates 9 rotatably installed at the bottom of the feeding hopper 8. The cylinders 10 are installed on both sides of the feeding hopper 8. The hinge blocks 11 are installed at the telescopic ends of the two groups of cylinders 10. There are multiple groups of hinge rods 12, and both ends are respectively connected to the hinge block 11 and the baffle 9.

[0030] There are cushion blocks 13 inside the support 1. There are multiple groups of cushion blocks 13 installed on the support 1 at the bottom of the feeding hopper 8. The cushion blocks 13 provide additional support for the conveyor belt, reducing the sinking and deformation of the conveyor belt under high load. This improves the stability of the conveying process, ensures that the stones remain flat during transportation, thereby enhancing the leveling effect and product quality. At the same time, the presence of the cushion blocks 13 also extends the service life of the conveyor belt and reduces maintenance requirements.

[0031] There are support rollers 14 on the support 1. There are multiple groups of support rollers 14 rotatably installed on the support 1. The support rollers 14 provide dynamic support for the conveyor belt, reducing the friction between the conveyor belt and the support 1. This not only reduces the wear of the conveyor belt but also improves the conveying efficiency. The setting of multiple groups of support rollers 14 ensures that the conveyor belt is evenly supported throughout its length, further improving the stability of stone conveying and leveling.

[0032] A protective cover 15 is installed at the bottom of the support 1 under the quantitative box 7. The protective cover 15 protects the quantitative box 7 and its internal mechanism, preventing external impurities from entering, improving the cleanliness and operating stability of the equipment. At the same time, it also plays a safety protection role, reducing the risk of operators contacting moving parts. The setting of the protective cover 15 extends the service life of the equipment and reduces the maintenance frequency.

[0033] Yielding grooves 16 are provided on both sides of the feeding hopper 8. A support rod 17 is installed on the baffle 6, and the support rod 17 slides in the yielding groove 16. The design of the yielding groove 16 and the support rod 17 allows the baffle 6 to move freely in the vertical direction while restricting its horizontal movement. This design improves the accuracy and stability of the baffle 6 adjustment, enabling the operator to flexibly adjust the position of the baffle 6 according to different stone characteristics, optimizing the stone distribution. At the same time, this sliding mechanism also reduces the friction and wear during the adjustment process.

[0034] In this embodiment, the stone first enters the quantitative box 7 and then falls into the feed hopper 8. Two sets of baffles 9 are rotatably installed at the bottom of the feed hopper 8 to control the release of the stone. When the stone needs to be released, the hinge block 11 at the telescopic end of the cylinder 10 drives the baffle 9 to rotate through the hinge rod 12, opening the bottom of the feed hopper 8 and allowing a certain amount of stone to fall onto the conveyor belt 4. When the predetermined amount is reached, the cylinder 10 contracts and the baffle 9 closes to stop the stone from falling. This design allows precise control of the amount of stone released each time, ensuring To ensure the uniformity of stone distribution on the conveyor belt 4, the motor 2 drives the two sets of transmission rollers 3 to rotate, driving the conveyor belt 4 to move. The stone enters the conveyor belt 4 from the feed hopper 5 and is transported to the designated position through the movement of the conveyor belt 4. The baffle 6 is set on the feed hopper 8 to control the flow and distribution of the stone. The stone on the conveyor belt 4 is evenly flattened during the movement to form a flat stone layer. The multiple sets of pads 13 and support rollers 14 in the support 1 provide support for the conveyor belt 4 to ensure the stability and flatness of the conveying process.

[0035] In this embodiment, adjustment mechanisms are provided at both ends of the support rod 17, and the adjustment mechanisms include a bracket 18, a screw 19, a transmission block 20, a socket 21 and a handle 22. The bracket 18 is mounted on the support 1, the screw 19 is threadedly connected to the bracket 18, the transmission block 20 is rotatably mounted at the bottom end of the screw 19, the socket 21 is provided on the transmission block 20, and the handle 22 is rotatably mounted on the bracket 18 and threadedly connected to the screw 19. This precision adjustment system allows the operator to accurately control the position of the baffle 6 by rotating the handle 22. The rotation of the screw 19 is converted into vertical movement through the transmission block 20, realizing the conversion from rotational motion to linear motion. This design provides highly precise position control, enabling the operator to make fine adjustments according to different stone characteristics to optimize stone distribution and paving effects.

[0036] A card slot 23 is provided on the inner wall of the socket 21, and a card strip 24 is provided on the outer wall of the support rod 17. The card strip 24 is adapted to the card slot 23. The cooperation between the card slot 23 and the card strip 24 enhances the stability and reliability of the adjustment mechanism. This design ensures that the support rod 17 will not rotate or deflect during the adjustment process, thereby ensuring the accuracy of the adjustment. At the same time, this locking mechanism also facilitates the rapid installation and disassembly of the support rod 17, thereby improving the maintenance efficiency of the equipment.

[0037] A slide bar 25 is installed on the inner side of the bracket 18, and the slide bar 25 is slidably connected to the transmission block 20. The sliding connection between the slide bar 25 and the transmission block 20 further enhances the smoothness and accuracy of the adjustment process. This design reduces the shaking and offset of the transmission block 20 during movement, ensuring the linearity and consistency of the adjustment action. At the same time, the slide bar 25 also shares part of the load, reduces the wear of the screw 19, and extends the service life of the adjustment mechanism.

[0038] More specifically, the adjusting mechanism is used to precisely control the position of the baffle 6. The operator rotates the handle 22 to drive the screw 19 to rotate. The rotation of the screw 19 is converted into a vertical movement through the transmission block 20. The jack 21 on the transmission block 20 is connected to the support rod 17, thereby adjusting the height of the baffle 6. The clamping strips 24 at both ends of the support rod 17 cooperate with the clamping grooves 23 on the inner wall of the jack 21 to ensure the stability of the adjustment. The sliding strip 25 inside the bracket 18 is slidably connected to the transmission block 20, further ensuring the smoothness and precision of the adjustment process. This design allows for flexible adjustment of the position of the baffle 6 according to the characteristics and requirements of different stones, optimizing the distribution and paving effect of the stones.

[0039] During use, the stones first enter the metering box 7 and then fall into the feed hopper 8. Two groups of baffle plates 9 are rotatably installed at the bottom end of the feed hopper 8 to control the release of the stones. When it is necessary to release the stones, the hinge block 11 at the telescopic end of the cylinder 10 drives the baffle plate 9 to rotate through the hinge rod 12, opening the bottom of the feed hopper 8 to allow a certain amount of stones to fall onto the conveyor belt 4. When the predetermined amount is reached, the cylinder 10 contracts, the baffle plate 9 closes, and the stone falling stops. This design allows for precise control of the amount of stones released each time, ensuring the uniformity of the stone distribution on the conveyor belt 4. The motor 2 drives two groups of drive rollers 3 to rotate, driving the conveyor belt 4 to move. The stones enter the conveyor belt 4 from the feeding hopper 5 and are conveyed to the designated position through the movement of the conveyor belt 4. The baffle 6 is arranged on the feed hopper 8 to control the flow rate and distribution of the stones. The stones on the conveyor belt 4 are evenly paved during the movement process to form a flat stone layer. Multiple groups of cushion blocks 13 and support rollers 14 in the support 1 provide support for the conveyor belt 4, ensuring the stability and flatness of the conveying process.

[0040] The adjusting mechanism is used to precisely control the position of the baffle 6. The operator rotates the handle 22 to drive the screw 19 to rotate. The rotation of the screw 19 is converted into a vertical movement through the transmission block 20. The jack 21 on the transmission block 20 is connected to the support rod 17, thereby adjusting the height of the baffle 6. The clamping strips 24 at both ends of the support rod 17 cooperate with the clamping grooves 23 on the inner wall of the jack 21 to ensure the stability of the adjustment. The sliding strip 25 inside the bracket 18 is slidably connected to the transmission block 20, further ensuring the smoothness and precision of the adjustment process. This design allows for flexible adjustment of the position of the baffle 6 according to the characteristics and requirements of different stones, optimizing the distribution and paving effect of the stones.
