Description

Technical Field

[0001] The utility model relates to the technical field of stone processing equipment, in particular to a novel thickness fixing and polishing equipment. Background Art

[0002] In the processing and production of stones or tiles, it is necessary to polish and fix the thickness of their surfaces. During the polishing process, the equipment needs to install multiple polishing components and thickness fixing components. These mechanisms are heavy, and when running, the moving mechanism needs to bear a great deal of gravity. Currently, most moving mechanisms on the market use slide rails to connect the crossbeams, and install the polishing components and thickness fixing components on the crossbeams. Since the slide rails are prone to deformation under heavy pressure, and there is no extra gap in the sliding connection between the slide rails and the sliders, if there are residues from processing on the slide rails, the sliders are likely to scratch the slide rails during the moving process, resulting in poor operation of the equipment and easily affecting the processing quality.

[0003] The technical content disclosed in the Chinese patent document (Publication No.: CN106078390A, Patent Name: A Thickness Fixing and Polishing Equipment for Stone Surfaces) is as follows: It includes a frame, a six-head thickness fixing component arranged on the frame for performing thickness fixing operations on the stone surface, a thickness fixing driving mechanism for driving the above six-head thickness fixing mechanism to reciprocate along the width direction of the frame, and a conveying mechanism arranged at the bottom end of the frame for conveying the stone to reciprocate along its length direction (in this embodiment, the conveying mechanism is a belt conveying mechanism). At the same time, the thickness fixing and polishing equipment also includes a polishing component for performing polishing operations on the stone surface and a polishing driving mechanism for driving the polishing component to reciprocate along the width direction of the frame. Among them, the six-head thickness fixing component and the polishing component are staggeredly and oppositely installed on both sides of the frame in the width direction. The above polishing component includes a plurality of polishing heads arranged side by side (two in this embodiment, and the actual number is set according to actual needs), a polishing driving mechanism for driving the plurality of polishing heads to perform horizontal rotary polishing movements, and driving cylinders for respectively driving the plurality of polishing heads to move vertically up and down.

[0004] From the above implementation, it can be seen that the equipment is provided with a polishing driving mechanism to drive the polishing heads to move, but the structure of the polishing driving mechanism is not specifically disclosed. Most polishing driving mechanisms on the market use slide rails to achieve movement. Slide rails have high precision and high cost, and long slide rails are prone to deformation. Since the polishing heads are heavy, it is easy to cause wear and tear of the slide rails. Summary of the Utility Model

Detailed implementation manners

[0045] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0046] As Figures 1 to 15As shown in the figure, a new type of thickness-fixed polishing device is used for thickness-fixing and polishing of stones, tiles, etc. It includes a conveying component 1. Above the conveying component 1, there are a grinding moving mechanism 2 and a thickness-fixing moving mechanism 4. The structures of the grinding moving mechanism 2 and the thickness-fixing moving mechanism 4 are the same. There are no less than one grinding component 3 connected to the grinding moving mechanism 2, and no less than one thickness-fixing component 5 connected to the thickness-fixing moving mechanism 4. The stone enters from one end of the thickness-fixing component 5 and is placed on the conveying component 1. The conveying component 1 drives the stone to pass under the thickness-fixing component 5. The thickness-fixing component 5 performs thickness-fixing grinding on the surface of the stone. After the thickness-fixing is completed, the stone is sent by the conveying component 1 to under the grinding component 3. The grinding component 3 grinds and polishes the surface of the stone. Finally, the stone is output from the other end of the conveying component 1.

[0047] The thickness-fixing moving mechanism 4 includes a moving base frame 401. On the moving base frame 401, there are rollers 4012. The moving base frame 401 is slidably connected to a moving table 403. The moving table 403 is connected to a cross beam 406. The thickness-fixing component 5 is connected to the cross beam 406. On the moving base frame 401, there is a sliding table 4011. The rollers 4012 are laid on the sliding table 4011. The lower end of the moving table 403 is connected to a sliding plate 4031. The sliding plate 4031 slides above the rollers 4012. The sliding table 4011 is fitted into the limiting strips protruding from both sides of the lower end of the moving table 403. Compared with the traditional method of using a slide rail and a slider to realize the movement of the cross beam 406, the contact area between the moving table 403 and the upper part of the sliding table 4011 is larger. Therefore, the stress area is larger. The moving table 403 is in contact with the rollers 4012. Therefore, each roller 4012 dispersedly bears a part of the pressure, so that the pressure borne by a single roller 4012 is small and it is not easy to deform. Moreover, the sliding table 4011 is fitted into the limiting strips protruding from both sides of the lower end of the moving table 403, so that the sliding table 4011 will not overturn to the left and right, making the whole operation process more stable.

[0048] A moving driving motor 402 is arranged on the side of the cross beam 406. The moving driving motor 402 is connected to an internal gear 4021. The moving driving motor 402 is connected to a connecting shaft 407. The connecting shaft 407 is provided with a gear section 4071. The internal gear 4021 is meshed and connected with the gear section 4071. Both ends of the connecting shaft 407 are meshed and connected with a moving gear 404. The moving gear 404 is connected to the moving base frame 401. The moving gear 404 is arranged parallel to the sliding table 4011. Therefore, the moving driving motor 402 drives the moving gear 404 to rotate. The moving gear 404 is meshed and connected with a moving rack 405, thereby providing power for the movement of the moving table 403 on the moving base frame 401.

[0049] The thickness fixing component 5 includes a thickness fixing base plate 501. A thickness fixing lifting seat 502 is slidably connected to the thickness fixing base plate 501, and a thickness fixing component 506 is rotatably connected to the thickness fixing lifting seat 502. The thickness fixing base plate 501 includes a plate body 5011, and first lubricating oil grooves 50111 are arranged on both sides of the plate body 5011. Lifting slide rails 5023 are arranged on both sides of the thickness fixing lifting seat 502, and a second lubricating oil groove 50231 and a third lubricating oil groove 50232 are arranged on the lifting slide rails 5023. The first lubricating oil grooves 50111, the second lubricating oil grooves 50231 and the third lubricating oil grooves 50232 are used to store solid lubricating grease or liquid lubricating oil. Therefore, when the thickness fixing grinding head 5065 moves up and down, the lifting slide rails 5023 can be fully lubricated, avoiding rusting of the lifting slide rails 5023 and affecting the lifting of the thickness fixing lifting seat 502.

[0050] The plate body 5011 is connected to an outer fixing plate 5013. An inner grinding plate 5012 is connected to the side of the outer fixing plate 5013 close to the plate body 5011. A chute is formed between the inner grinding plate 5012 and the plate body 5011. The inner grinding plate 5012 faces the first lubricating oil groove 50111. The lifting slide rails 5023 slide inside the chute. The inner grinding plate 5012 is made of stainless steel with high wear resistance. Since the inner grinding plate 5012 can be detached separately, the surface of the inner grinding plate 5012 close to the lifting slide rails 5023 can be processed and produced separately, ensuring the flatness of the surface of the inner grinding plate 5012 close to the lifting slide rails 5023 and further ensuring the smooth sliding of the lifting slide rails 5023.

[0051] The second lubricating oil groove 50231 includes a transverse groove 502311 and a vertical groove 502312 that communicate with each other. The transverse groove 502311 and the vertical groove 502312 are perpendicular to each other. The third lubricating oil groove 50232 is on a plane perpendicular to the second lubricating oil groove 50231, that is, lubricating oil grooves are arranged on the side surfaces of the lifting slide rails 5023. When the lifting slide rails 5023 slide, the lubricating oil in these lubricating oil grooves can be driven out, making the sliding of the lifting slide rails 5023 smoother. On the other hand, since the outer surface of the lifting slide rails 5023 is covered with grease, the outer surface of the lifting slide rails 5023 is not easy to rust, making the lifting slide rails 5023 more durable.

[0052] The thickness - setting component 506 includes a thickness - setting motor 5061. The thickness - setting motor 5061 is connected to a connecting rotating shaft 5064, and the other end of the rotating shaft 5064 is connected to a thickness - setting grinding head 5065. The rotating shaft 5064 is connected to a first bearing 5062 and a second bearing 5063. The thickness - setting lifting seat 502 is provided with a lifting connection hole 5021 and a grinding - shaft connection hole 5022. The first bearing 5062 is arranged at the upper end of the grinding - shaft connection hole 5022, and the second bearing 5063 is arranged at the lower end of the grinding - shaft connection hole 5022. The thickness - setting grinding head 5065 includes a grinding - head base 50651. The lower end of the grinding - head base 50651 is connected to a grinding disk 50652. The grinding disk 50652 is connected to a number of grinding blocks 50653. There is a gap between every two grinding blocks 50653. Therefore, when the thickness - setting grinding head 5065 grinds the stone, the powder debris ground from the stone can flow out from the gaps between every two grinding blocks 50653, and will not accumulate under the grinding disk 50652. This makes the grinding of the grinding disk 50652 on the stone smoother, and the operation of the grinding disk 50652 will not be stuck due to the accumulation of powder debris.

[0053] The thickness - setting lifting seat 502 is provided with a clearance groove 5024, and the clearance groove 5024 is used to reduce the weight of the thickness - setting lifting seat 502, making the operation smoother.

[0054] The thickness - setting base plate 501 is connected to a lifting motor 503. The lifting motor 503 is connected to a reduction box 504. The reduction box 504 is connected to a lifting screw 505. The lifting screw 505 is in threaded connection with the thickness - setting lifting seat 502. The lifting motor 503 drives the thickness - setting lifting seat 502 to lift.

[0055] The lower end of the thickness - setting lifting seat 502 is connected to a protective box 507. The protective box 507 includes a first cover body 5071 and a second cover body 5072. A door - lock sliding groove 5073 is arranged on the second cover body 5072. An observation door 5074 is inserted into the door - lock sliding groove 5073. A door handle 5075 is arranged on the observation door 5074. Both ends of the observation door 5074 are connected to the second cover body 5072 through door locks 5076. The first cover body 5071 and the second cover body 5072 enclose the thickness - setting grinding head 5065 inside. Therefore, when the thickness - setting grinding head 5065 grinds, the grinding water liquid will not splash to other places and will not contaminate the equipment. And an observation door 5074 is provided. When the equipment stops, the observation door 5074 can be opened to observe the state of the thickness - setting grinding head 5065. After detecting no errors, the next grinding process can be carried out.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
