Description

Technical Field

[0001] This application relates to the field of ceramic manufacturing technology, and in particular to a double-head rolling mill for manufacturing ceramics. Background Technology

[0002] Ceramics is a general term for pottery and porcelain, and it is also a type of Chinese arts and crafts. As early as the Neolithic Age, my country already had rugged and simple painted pottery and black pottery. Pottery and porcelain differ in texture and properties. Pottery is made primarily of clay with high viscosity and plasticity; it is opaque, has fine pores, and slight water absorption, producing a dull sound when struck. Porcelain, on the other hand, is made of clay, feldspar, and quartz; it is translucent, non-absorbent, corrosion-resistant, and has a hard, dense body, producing a crisp sound when struck.

[0003] A roller burnishing machine is a machine used to process smooth rods. Smooth rods (also called piston rods, etc.) are commonly used in motors, cylinders, hydraulic cylinders, valves, linear bearings, and oil pumps. When used on ceramics, a double-head roller burnishing machine is required for rolling.

[0004] While existing double-head rolling machines can roll ceramic blanks in two sets of molds simultaneously, achieving the effect of double-head rolling, the drawback is that the two sets of rolling heads are fixed at the bottom of the main shaft and the driven shaft, respectively. As a result, when the surfaces of the two sets of rolling heads wear out due to long-term use, they need to be replaced, and existing technology cannot easily disassemble and replace them. Utility Model Content

[0005] This application provides a double-head rolling mill for manufacturing ceramics, which solves the problem that the rolling head cannot be easily disassembled and replaced in the prior art.

[0006] This application provides a double-head rolling mill for manufacturing ceramics, including a worktable, an mounting frame above the worktable, a drive shaft inside the mounting frame, a mounting bracket fixed to the outer wall of the drive shaft, a rotary knob on the outer side of the mounting bracket, left and right threaded screws fixedly connected to the side of the rotary knob, two sets of second screw nuts connected to the outer wall of the left and right threaded screws, the two sets of second screw nuts respectively installed inside a T-shaped guide plate, a limit block fixed to the side of the T-shaped guide plate, two sets of sliding grooves opened on the side of the bottom end of the drive shaft, a rolling head below the drive shaft, a fixing block installed on the top of the rolling head, and two sets of limit slots opened on the outer side of the fixing block.

[0007] Preferably, a first drive motor is fixedly installed on the outer side of the worktable, and the first drive motor is connected to a reciprocating lead screw.

[0008] Preferably, the outer wall of the reciprocating lead screw is connected to a first lead screw nut, which is fixed inside the mounting frame.

[0009] Preferably, two sets of first guide slide rods are fixed on the inner side of the mounting frame, and a drive cylinder is fixedly installed on the top of the mounting frame.

[0010] Preferably, the drive cylinder is connected to a fixed frame via a telescopic shaft, and connecting blocks are fixed on both sides of the fixed frame. A second guide slide rod is connected inside the connecting block, and a second drive motor is installed on the top of the fixed frame.

[0011] Preferably, a third guide slide rod is internally connected to the two sets of T-shaped guide plates.

[0012] Preferably, a driving gear is fixed to the outer wall of the driving shaft, a driven gear is meshed with one side of the driving gear, a driven shaft is fixed inside the driven gear, and a rolling head is connected to the lower part of the driven shaft.

[0013] Preferably, the top of the workbench is fixed with multiple sets of bearings, and the bearings are internally connected to molds. The distance between two sets of molds is the same as the distance between two sets of rolling heads.

[0014] Beneficial effects:

[0015] Considering the limitations of existing technology in easily disassembling and replacing the two sets of rolling heads, this patent addresses the issue that when a new rolling head needs to be replaced, rotating a knob causes the left and right threaded screws to rotate. These screws, connected to the outer walls of two sets of second screw nuts, drive two sets of T-shaped guide plates in opposite directions. These T-shaped guide plates, in turn, drive two sets of limiting blocks in opposite directions, disengaging the limiting blocks from their respective limiting slots. Then, the fixing block at the top of the rolling head can be pulled out from the bottom of the drive shaft, allowing the rolling head to be removed. Similarly, the other rolling head can be removed from the bottom of the driven shaft. This allows for quick and individual disassembly and replacement of the two rolling heads, improving component replacement efficiency and further enhancing the overall efficiency of ceramic manufacturing.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figure 1-6 The double-head rolling mill for manufacturing ceramics shown includes a worktable 1, an mounting frame 5 above the worktable 1, a drive shaft 12 inside the mounting frame 5, a mounting bracket 13 fixed to the outer wall of the drive shaft 12, a rotary knob 14 on the outer side of the mounting bracket 13, left and right threaded screws 15 fixedly connected to the side of the rotary knob 14, two sets of second screw nuts 16 connected to the outer wall of the left and right threaded screws 15, the two sets of second screw nuts 16 respectively installed inside a T-shaped guide plate 17, a limit block 19 fixed to the side of the T-shaped guide plate 17, two sets of sliding grooves 20 opened on the side of the bottom end of the drive shaft 12, a rolling head 21 below the drive shaft 12, a fixing block 22 installed on the top of the rolling head 21, and two sets of limit slots 23 opened on the outer side of the fixing block 22.

[0033] The mounting frame 5 drives the inner rolling device to move horizontally. The drive shaft 12 drives a set of rolling heads 21 to rotate. The mounting bracket 13 mounts the clamping and fixing mechanism. The rotary knob 14 drives the left and right threaded screws 15 to rotate. The left and right threaded screws 15 drive the two sets of second screw nuts 16 to move in opposite directions. The two sets of second screw nuts 16 drive the two sets of T-shaped guide plates 17 to move in opposite directions. The two sets of T-shaped guide plates 17 drive the two sets of limiting blocks 19 to move in opposite directions. The two sets of sliding grooves 20 allow the two sets of limiting blocks 19 to slide inside. The rolling head 21 rolls the ceramic blank inside the mold 28. The fixing block 22 is fixed to the top of the rolling head 21 and is inserted into the bottom of the drive shaft 12. Two sets of limiting slots 23 allow two sets of limiting blocks 19 to be inserted into them, which can limit and fix the fixing block 22, thereby enabling the installation of the rolling head 21 and facilitating the installation and removal of the rolling head 21.

[0034] A first drive motor 2 is fixedly installed on the outer side of the workbench 1, and the first drive motor 2 is connected to a reciprocating lead screw 3.

[0035] The first drive motor 2 drives the reciprocating screw 3 to rotate via a drive shaft. The reciprocating screw 3 then drives the first screw nut 4 to move horizontally.

[0036] The outer wall of the reciprocating lead screw 3 is connected to the first lead screw nut 4, which is fixed inside the mounting frame 5.

[0037] Among them, the first lead screw nut 4 plays the role of driving the mounting frame 5 to move horizontally.

[0038] Two sets of first guide slide rods 6 are fixed on the inner side of the mounting frame 5, and a drive cylinder 7 is fixedly installed on the top of the mounting frame 5.

[0039] Among them, the two sets of first guide slide rods 6 guide the movement of the mounting frame 5. The drive cylinder 7 drives the fixed frame 8 to move up and down.

[0040] The drive cylinder 7 is connected to a fixed frame 8 via a telescopic shaft. Connecting blocks 9 are fixed on both sides of the fixed frame 8. A second guide slide rod 10 is connected inside the connecting block 9. A second drive motor 11 is installed on the top of the fixed frame 8.

[0041] The fixed frame 8 serves to mount the second drive motor 11. The two sets of connecting blocks 9 guide the movement of the fixed frame 8. The second guide slide rod 10 limits the movement of the connecting blocks 9. The second drive motor 11 drives the active rotating shaft 12 to rotate via the drive shaft.

[0042] The two sets of T-shaped guide plates 17 are internally connected by a third guide slide rod 18.

[0043] Among them, the third guide slide rod 18 serves to guide the two sets of T-shaped guide plates 17.

[0044] A drive gear 24 is fixed to the outer wall of the drive shaft 12. A driven gear 25 is meshed with one side of the drive gear 24. A driven shaft 26 is fixed inside the driven gear 25. A rolling head 21 is connected to the lower part of the driven shaft 26.

[0045] The driving gear 24 drives the driven gear 25 to rotate. The driven gear 25 drives the driven shaft 26 to rotate. The driven shaft 26 drives another set of rolling heads 21 to rotate.

[0046] Multiple sets of bearings 27 are fixed to the top of the workbench 1. Molds 28 are connected inside the bearings 27. The distance between two sets of molds 28 is the same as the distance between two sets of rolling heads 21.

[0047] The bearing 27 allows the mold 28 to rotate inside it. The mold 28 serves to hold the ceramic blank.

[0048] Working principle: When using this double-head rolling mill for manufacturing ceramics, the ceramic blank is first placed into multiple sets of molds 28, and then the drive cylinder 7 is started, which causes the fixed frame 8 to move downward, thus causing the fixed frame 8 to drive the two sets of rolling heads 21 below to move downward.

[0049] Then, the second drive motor 11 is operated so that the second drive motor 11 drives the active rotating shaft 12 to rotate through the drive shaft. The active rotating shaft 12 drives a set of rolling heads 21 to rotate. The outer wall of the active rotating shaft 12 is fixed with an active gear 24. The active gear 24 drives the driven gear 25 to rotate. The driven gear 25 drives another set of rolling heads 21 to rotate. In this way, the two sets of rolling heads 21 rotate at the same time, so that the ceramic blanks in the two sets of molds 28 can be rolled, thus achieving the effect of double-head rolling.

[0050] When a new rolling head 21 needs to be replaced, rotate the knob 14 to drive the left and right threaded screws 15 to rotate. The left and right threaded screws 15 are connected to two sets of second screw nuts 16 on their outer walls. The two sets of second screw nuts 16 drive two sets of T-shaped guide plates 17 to move in opposite directions. The two sets of T-shaped guide plates 17 drive two sets of limit blocks 19 to move in opposite directions. This causes the two sets of limit blocks 19 to disengage from the two sets of limit slots 23. Then, the fixing block 22 fixed on the top of the rolling head 21 is pulled out from the bottom of the drive shaft 12, so that the rolling head 21 can be removed from the drive shaft 12. Similarly, the other rolling head 21 can be removed from the bottom of the driven shaft 26, thus achieving the effect of facilitating the removal and replacement of the rolling head 21.

[0051] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
