Description

A feed conveyor for continuous grinding of marble slabs Technical Field

[0001] This utility model relates to the technical field of conveying devices, and in particular to a feed conveying device for continuous grinding of marble slabs. Background Technology

[0002] Marble slab grinding is a crucial step in stone processing, primarily involving rough grinding, fine grinding, precision grinding, and polishing. Feeding and conveying are essential components of marble processing. Existing technology publication number CN209720829U discloses a marble processing conveyor device. This device includes a frame with a conveyor belt mounted on it. The lower end of the frame has several symmetrically arranged circular moving grooves. Pistons are slidably connected to the walls of these grooves. A moving rod is fixedly connected to the end of the piston furthest from the bottom of the groove, and a caster wheel is fixedly mounted to the end of the moving rod furthest from the piston, passing through the groove openings. Support rods are symmetrically fixedly connected to the upper end of the frame. A support plate is positioned above the conveyor belt, with its lower end fixedly connected to the upper end of the support rods. The support plate has threaded holes, into which threaded rods are threaded, with both ends of the threaded rods passing through the holes and extending outwards. A scraper is positioned below the support plate. However, if the marble cannot be fixed and limited during the conveying process, it is easy for the marble to slip during processing and feeding, which will affect the processing quality. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a continuous grinding feed conveying device for marble slabs that can clamp and fix the front and rear ends of the marble slab during conveying and feeding, ensuring the stability of conveying, avoiding slippage during processing and feeding, and ensuring the processing effect.

[0004] This utility model discloses a continuous grinding feed conveying device for marble slabs, comprising a conveying component, a supporting component, a clamping component, and an adjusting component. The bottom of the conveying component is mounted above the supporting component, and the clamping component is mounted on the conveying component. The adjusting component is mounted at both ends of the top of the conveying component. The supporting component supports the conveying component, and the installation height of the supporting component can be adjusted according to the actual installation situation. The conveying component can convey the marble slab at a uniform speed. The clamping component can clamp and fix the front and rear ends of the marble slab during conveying and feeding, ensuring stability during conveying and preventing slippage during processing, thus ensuring the processing effect. The adjusting component can adjust the clamping position of the clamping component, which is suitable for marble slabs of different widths.

[0005] Preferably, the conveying component includes a frame, multiple conveying shafts, a transmission box, a conveying motor, and multiple conveying rollers. Multiple conveying shafts are rotatably mounted inside the frame. The transmission box is installed at the front end of the frame, and the input end of each conveying shaft is connected to the transmission box. The conveying motor is installed at the front end of the transmission box and connected to its input end. Conveying rollers are installed on the outer wall of the middle section of each conveying shaft. Starting the conveying motor drives the multiple conveying shafts to rotate via the transmission box. The marble slab is placed on the top of the conveying rollers, and the conveying shafts drive the conveying rollers to rotate, feeding and conveying the marble slab. The conveying rollers reduce noise and increase friction.

[0006] Preferably, the support components include multiple fixed seats, multiple outriggers, two transverse connecting frames, two connecting rods, and multiple friction plates. Fixed seats are installed at the four corners of the bottom of the frame. The tops of the outriggers are bolted to the bottom of the fixed seats, and friction plates are installed at the bottom of the outriggers. Transverse connecting frames connect the outer walls of the front and rear outriggers, and connecting rods connect the outer walls of the left and right outriggers. Outriggers of appropriate height are selected according to actual installation needs and connected to the fixed seats with bolts. The bottom of the equipment is supported by the outriggers and friction plates. The transverse connecting frames and connecting rods connect multiple outriggers into a whole to ensure stability.

[0007] Preferably, the clamping component includes two sets of sprockets, two transmission chains, two sets of connecting plates, two sets of clamping rods, and two sets of clamping plates. Sprockets are installed on the outer walls of the conveying shafts at both ends of the conveying roller. The two transmission chains are respectively installed on the two sets of sprockets on the front and rear sides. Multiple connecting plates are evenly connected to the upper surface of the transmission chains. The clamping rods are located above the connecting plates, and clamping plates are installed at the ends of the two clamping rods that are close to each other. When the marble is conveyed on the conveying roller, the conveying shaft synchronously drives the sprockets to rotate, the sprockets drive the transmission chains to rotate, and at the same time, the clamping rods push the clamping plates to contact the front and rear ends of the marble to clamp it, ensuring stability during conveying, avoiding slippage during processing feed, and ensuring processing effect.

[0008] Preferably, the adjusting components include two L-shaped fixed plates, two sets of electric telescopic rods, two protrusions, two sets of mounting brackets, and two sets of push wheels. The two L-shaped fixed plates are symmetrically installed at the front and rear ends of the top of the machine frame. Multiple electric telescopic rods are installed on the L-shaped fixed plates. Protrusions are installed at the telescopic ends of the electric telescopic rods. The left and right ends of the protrusions are set as arcs. A mounting bracket is installed at the top of the clamping rod away from the clamping plate. Push wheels are rotatably installed on the mounting bracket. According to the width of the marble slab to be processed, the electric telescopic rod is started to push the protrusions to move, and the distance between the two protrusions is adjusted. When the clamping rod drives the push wheels to move and contact the protrusions, it pushes the clamping rod to slide on the connecting plate, which can adjust the distance between the two clamping plates and is suitable for marble slabs of different widths.

[0009] Preferably, it also includes two sets of sliding rods, two sets of limiting sliders, and two sets of springs. The top of the connecting plate is provided with an adjusting groove. The sliding rods are installed in the adjusting grooves, and the limiting sliders are slidably installed in the adjusting grooves and on the outer wall of the sliding rods. The springs are fitted on the outer wall of the sliding rods, with one end of the spring connected to the limiting slider and the other end connected to the inner wall of the adjusting groove. After the push wheel disengages from the protrusion, the spring restores its elasticity and pulls the limiting slider to slide on the sliding rod, causing the clamping rod to slide on the connecting plate, which in turn moves the clamping plate to both sides to release the clamping of the marble slab.

[0010] Preferably, it also includes two sets of limiting rods, with multiple limiting rods and electric telescopic rods alternately slidably installed on the L-shaped fixed plate, and the limiting rods connected to the outer wall of the protrusion; when the electric telescopic rod pushes the protrusion to move, the protrusion drives the limiting rods to slide on the L-shaped fixed plate, limiting and guiding them, enhancing the connection strength, and ensuring stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the supporting component supports the conveying component, and the installation height can be adjusted by selecting the supporting component according to the actual installation situation. The conveying component can convey the marble slab at a uniform speed. The clamping component can clamp and fix the front and rear ends of the marble slab during the conveying feed to ensure the stability during conveying, avoid slippage during processing feed, and ensure the processing effect. The adjusting component can adjust the clamping position of the clamping component, which is suitable for marble slabs of different widths. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

The top of the support leg 7 is bolted to the bottom of the fixed seat 6. A friction plate 10 is installed at the bottom of the support leg 7. A transverse connecting frame 8 is connected between the outer walls of the front and rear support legs 7. A connecting rod 9 is connected between the outer walls of the left and right support legs 7. Sprockets 11 are installed on the outer walls of the conveyor shaft 2 at both ends of the conveyor roller 5. Two transmission chains 12 are respectively installed on the two sets of sprockets 11 on the front and rear sides. Multiple connecting plates 13 are evenly connected to the upper surface of the transmission chain 12. A clamping rod 14 is located above the connecting plate 13 and the two clamping rods 14 are close together.

The slide rod 16 is installed in the adjustment groove, and the limiting slider 17 is slidably installed in the adjustment groove and on the outer wall of the slide rod 16. The spring 18 is fitted on the outer wall of the slide rod 16. One end of the spring 18 is connected to the limiting slider 17, and the other end of the spring 18 is connected to the inner wall of the adjustment groove. Two L-shaped fixing plates 19 are symmetrically installed at the front and rear ends of the top of the frame 1. Multiple electric telescopic rods 20 are installed on the L-shaped fixing plates 19. The telescopic ends of the electric telescopic rods 20 are equipped with protrusions 21. The left and right ends of the protrusions 21 are set as arcs. A mounting bracket 22 is installed at the top of the clamping rod 14 away from the clamping plate 15. A push wheel 23 is rotatably installed on the mounting bracket 22. Multiple limiting support rods 24 are alternately slidably installed on the L-shaped fixing plates 19 with the electric telescopic rods 20. The limiting support rods 24 are connected to the outer wall of the protrusions 21.

[0020] Depending on the required marble slab width, the electric telescopic rod 20 is activated to move the protrusion 21, adjusting the distance between the two protrusions 21. When the drive wheel 23 of the clamping rod 14 moves and contacts the protrusion 21, it pushes the clamping rod 14 to slide on the connecting plate 13, adjusting the distance between the two clamping plates 15. This is suitable for marble slabs of different widths.

At the same time, the clamping rod 14 pushes the clamping plates 15 to contact the front and rear ends of the marble, clamping it to ensure stability during conveying and prevent slippage during processing, thus ensuring processing results. Depending on the required marble slab width, the electric telescopic rod 20 is activated to move the protrusion 21, adjusting the distance between the two protrusions 21. When the electric telescopic rod 20 moves the protrusion 21, the protrusion 21 drives the limiting wheel 23 to move. The support rod 24 slides on the L-shaped fixed plate 19, limiting and guiding it, enhancing connection strength and ensuring stability. When the clamping rod 14 drives the push wheel 23 to move and contact the protrusion 21, it pushes the clamping rod 14 to slide on the connecting plate 13, which can adjust the distance between the two clamping plates 15, suitable for marble slabs of different widths.

At the same time, the clamping rod 14 pushes the clamping plate 15 to contact the front and rear ends of the marble, clamping it to ensure stability during conveying, avoid slippage during processing feed, and ensure processing effect. After the push wheel 23 disengages from the protrusion 21, the spring 18 restores its elasticity and pulls the limiting slider 17 to slide on the slide rod 16, causing the clamping rod 14 to slide on the connecting plate 13, driving the clamping plate 15 to move to both sides to release the clamping of the marble slab.

The support legs 7 and friction plates 10 support the bottom of the equipment. Multiple support legs 7 can be connected as a whole via a transverse connecting frame 8 and a connecting rod 9. The conveyor motor 4 is started, driving multiple conveyor shafts 2 to rotate via a transmission box 3. The marble slab is placed on the top of the conveyor roller 5, and the conveyor shafts 2 drive the conveyor roller 5 to rotate, feeding and conveying the marble slab. While the marble is conveyed on the conveyor roller 5, the conveyor shafts 2 synchronously drive the sprocket 11 to rotate. 11 drives the transmission chain 12 to rotate. According to the required width of the marble slab to be processed, the electric telescopic rod 20 is activated to push the protrusion 21 to move and adjust the distance between the two protrusions 21.
