Description

Technical Field

[0001] The utility model relates to a grinding machine for the bottom of ceramic finished products. Background Art

[0002] The bottom of a ceramic finished product usually has a bottom edge, and the bottom edge usually has problems such as rough surface and being easy to cut the user's hand. Therefore, special equipment for grinding the bottom edge is needed to process the bottom edge.

[0003] At present, the equipment for grinding the bottom edge usually uses a disc-shaped grinding disc that rotates continuously to grind the bottom edge of the ceramic finished product. For example, a ceramic product automatic grinding machine disclosed in a Chinese patent document with the publication number CN202377883U and the name of "Ceramic Product Automatic Grinding Machine" includes an upper frame and a lower frame. The lower frame is provided with a circulating conveyor belt and a first motor, and the circulating conveyor belt is driven by the first motor; the upper frame is equipped with a grinding disc assembly; the grinding disc assembly includes a horizontal grinding disc and a second motor for driving the horizontal grinding disc to rotate. The installation direction of the rotating shaft of the horizontal grinding disc is vertical, the rotating shaft of the horizontal grinding disc is connected to the rotating shaft of the second motor, and the horizontal grinding disc is located at the lowermost end of the grinding disc assembly; the upper frame is also provided with a vertical power mechanism for driving the grinding disc assembly to move up and down; the upper frame is fixedly installed with a first photoelectric eye device, and the grinding disc assembly is located in front of the first photoelectric eye device; a PLC programming controller is also provided. The first photoelectric eye device is connected to the PLC programming controller through a signal line, and the PLC programming controller is connected to the vertical power mechanism through a signal line.

[0004] However, the applicant found that the disadvantage of this processing equipment is that the grinding disc, that is, the disc-shaped grinding disc, the part used for grinding is its top surface or bottom surface. Therefore, during grinding, in fact, a plane of the grinding disc continuously rubs against the bottom edge of the ceramic finished product. Although the processing speed is relatively fast, there are many disadvantages: due to the large individual differences caused by the shrinkage of the ceramic finished product, and the lifting distance of the grinding disc during operation is preset, it is easy to cause the situation that the grinding disc descends to the lowest position but fails to contact the ceramic finished product or the grinding disc presses the ceramic finished product and damages it, and the probability is not low; the grinding accuracy is relatively low, and it is difficult to obtain fine grinding of the bottom edge. In particular, it is difficult for the grinding disc to grind the inner and outer sides of the bottom edge. Therefore, a smooth curved surface or multiple curved surfaces cannot be processed, and it is difficult to meet the increasingly high quality requirements for ceramic finished products. In addition, the cost of the grinding disc is high, and a large amount of electric energy is consumed for driving. Therefore, both the manufacturing cost and the use cost are relatively high. Moreover, the utilized area of the grinding disc is limited, and the unutilized part is wasted. Summary of the Utility Model

[0032] As Figure 12 , 13 shown, a ceramic finished product 7 processed according to an embodiment of the present application, the bottom of the ceramic finished product 7 has a bottom edge 701.

[0033] AsFigure 1-11 As shown in the figure, in an embodiment of the present application, a ceramic finished product bottom grinding machine has

[0034] a picking station A, at least one grinding station B, and a placing station C. Each station is sequentially distributed along the circular closed movement route of the ceramic finished product 7;

[0035] The ceramic finished product bottom grinding machine includes

[0036] an intermittent transfer mechanism 1, which rotates intermittently and carries at least one ceramic finished product 7 to stop at each station in turn along the movement route of the ceramic finished product 7;

[0037] a plurality of ceramic finished product clamping and rotating devices 2, which are respectively installed on the intermittent transfer mechanism 1, pick up the ceramic finished product 7 located at the picking station A, drive the ceramic finished product 7 to rotate at the grinding station B, and put down the ceramic finished product 7 at the placing station C;

[0038] at least one multi-angle grinding device 3. The multi-angle grinding device 3 includes a first bracket 301 and at least one multi-angle fine grinding mechanism 302 installed on the first bracket 301. The multi-angle fine grinding mechanism 302 simultaneously performs multi-angle fine grinding on the bottom edge 701 of the ceramic finished product 7;

[0039] The number of the grinding stations B and the multi-angle grinding devices 3 is the same and they correspond one by one. Each multi-angle grinding device 3 is arranged at the corresponding grinding station B.

[0040] Different multi-angle grinding devices 3 can be designed with different functions according to needs. For example, the first multi-angle grinding device 3 performs rough grinding on the bottom edge 701, and the second multi-angle grinding device 3 continues to perform fine grinding on the bottom edge 701; or, the first multi-angle grinding device 3 grinds the bottom edge 701 to obtain a first curved surface, and the second multi-angle grinding device 3 continues to grind the bottom edge 701 to obtain a second curved surface. The number of multi-angle fine grinding mechanisms 302 in the same multi-angle grinding device 3 depends on the number of ceramic finished products to be processed at a single station.

[0041] In an alternative embodiment, the number of the grinding stations B is one.

[0042] In an alternative embodiment, the number of the grinding stations B is three.

[0043] As Figure 1-3 shown, in an alternative embodiment of the present application, the number of the grinding stations B is two.

[0044] As Figure 4-6As shown, in one embodiment of the present application, the multi-angle fine grinding mechanism 302 includes at least two single-angle fine grinding units 3021, and the single-angle fine grinding unit 3021 includes a base 30211, a support frame 30212, an annular abrasive belt 30213, a first guide roller 30214, and a second guide roller 30215. The base 30211 is mounted on the first bracket 301, the support frame 30212 is mounted on the base 30211, both ends of the first guide roller 30214 and both ends of the second guide roller 30215 are rotatably mounted on the support frame 30212, and the annular abrasive belt 30213 is sleeved on the first guide roller 30214 and the second guide roller 30215. In this embodiment, the number of the single-angle fine grinding units 3021 is two.

[0045] like Figure 8 As shown, in one embodiment of the present application, a buffer cylinder 302111 is installed on the base 30211, the piston shaft of the buffer cylinder 302111 extends vertically upward, and the support frame 30212 is fixed on the piston shaft of the buffer cylinder 302111. The function of the buffer cylinder 302111 is that when the finished ceramic product 7 drops to the lowest point and its bottom edge abuts against the top of the annular abrasive belt 30213, the piston shaft of the buffer cylinder 302111 can shrink, thereby avoiding excessive pressure between the finished ceramic product 7 and the annular abrasive belt 30213 and causing damage to the components.

[0046] like Figure 8 As shown, in one embodiment of the present application, the first guide roller 30214 is located above the second guide roller 30215, and the axis of the first guide roller 30214 has an angle with the horizontal plane, and the angle of the angle is 1-10 degrees. Such a design is because the part of the top of the sand belt that bypasses the first guide roller 30214 (referred to as the grinding zone in this application) contacts the bottom edge of the finished ceramic product. In order to better process the bottom edge, the axis of the first guide roller 30214 has an angle with the horizontal plane, and the grinding zone can extend into the inside of the bottom edge or extend to the outside of the bottom edge to grind the inner wall or outer wall of the bottom edge. The producer can set the size of the angle according to the bottom edge contour to be obtained. In a preferred solution, the two sand belts are symmetrically arranged relative to the bottom edge of the finished ceramic product, and the round rod-shaped arc surfaces of the two sand belts have the same angle with the horizontal plane. Such a design can make the finished ceramic product more evenly stressed.

[0047] like Figure 5 , 6 As shown, in an optional embodiment of the present application, the number of the single-angle fine grinding units 3021 is two.

[0048] like Figure 8 , 9As shown in the figure, in an embodiment of the present application, an alternative embodiment, the single-angle fine grinding unit 3021 further includes a guide roller driving member 30216. The guide roller driving member 30216 is installed on the support frame 30212 and the guide roller driving member 30216 is connected to the second guide roller 30215 and drives the second guide roller 30215 to rotate.

[0049] As Figure 8 , 9 shown in the figure, in an embodiment of the present application, the guide roller driving member 30216 is a cylinder. One end of the second guide roller 30215 is provided with a one-way bearing 30217. An outer ring of the one-way bearing 30217 is fixed with a swing member 30218. The cylinder is installed on the support frame 30212 and a piston rod of the cylinder is connected to the swing member 30218. In this way, every time the cylinder expands and contracts once, it will drive the second guide roller 30215 to rotate an angle along the same rotation direction, thereby driving the endless abrasive belt 30213 to move a certain distance. Since an axis of the first guide roller 30214 has an included angle with a horizontal plane, a grinding area will move a certain distance along a longitudinal direction of the abrasive belt. This enables each part of the abrasive belt in the longitudinal direction to perform the grinding work in sequence, making full use of the abrasive belt.

[0050] As Figure 8 , 9 shown in the figure, in an embodiment of the present application, the single-angle fine grinding unit 3021 further includes a pressure roller 30219. Two ends of the pressure roller 30219 are respectively rotatably installed on the support frame 30212. The pressure roller 30219 presses the endless abrasive belt 30213 from the inside to the outside.

[0051] As Figure 10 , 11As shown in the figure, in one embodiment of the present application, the multi-angle fine grinding mechanism 302 further includes a position changing unit 3022.

The first mounting bracket 30221 is mounted on the first support 301. The screw rod 30223 is rotatably mounted on the first mounting bracket 30221. The left and right sides of the circumferential surface of the screw rod 30223 respectively have left-handed threads and right-handed threads. The first motor 30222 is mounted on the first mounting bracket 30221, and the output shaft of the first motor 30222 is connected to one end of the screw rod 30223 and drives the screw rod 30223 to rotate. The two screw sleeves 30224 are respectively sleeved on the screw rod 30223, and the two screw sleeves 30224 are respectively located on the left and right sides of the screw rod 30223 and are threadedly connected to the screw rod 30223. The bases 30211 of the two single-angle fine grinding units 3021 are respectively slidably mounted on the first mounting bracket 30221, and the two bases 30211 are respectively connected to the two screw sleeves 30224. In this embodiment, the first motor 30222 is a servo motor. Since the axis of the first guide roller 30214 has an angle with the horizontal plane, the grinding area will change a position along the transverse direction of the abrasive belt, which enables the abrasive belt to perform grinding work in each part of the transverse direction in turn, making full use of the abrasive belt.

[0052] As Figure 10 , 11 shown in the figure, in one embodiment of the present application, the first mounting bracket 30221 has at least one slide rail, and all the slide rails are parallel to the screw rod 30223. The two bases 30211 are respectively slidably sleeved on all the slide rails. In this embodiment, the number of the slide rails is two.

[0053] As Figure 10 , 11 shown in the figure, in one embodiment of the present application, a plurality of foldable and telescopic dust-proof cover assemblies are provided between the two bases 30211 and the first mounting bracket 30221. The function of these foldable and telescopic dust-proof cover assemblies is to prevent dust, waste generated during processing, etc. from entering the space below them.

[0054] As Figure 6 shown in the figure, in one embodiment of the present application, the multi-angle grinding device 3 further includes a flushing mechanism 304. The flushing mechanism 304 includes a plurality of water pipes 3041 communicated with an external water source. The number of the water pipes 3041 is the same as that of the multi-angle fine grinding mechanism 302 and they correspond one by one.

The inlet of the dispenser 3042 is connected to an external water source, and the number of outlets of the dispenser 3042 is the same as and corresponds one by one to the number of water pipes 3041, and each water pipe 3041 is respectively connected to a corresponding outlet.

[0056] As Figure 6 As shown in the figure, in an embodiment of the present application, the flushing mechanism 304 further includes a water receiving tank 3043 and multiple staggered waterproof plates. The water receiving tank 3043 is installed between all the multi-angle fine grinding mechanisms 302, and multiple staggered waterproof plates are respectively installed on the position changing units 3022 of each multi-angle fine grinding mechanism 302. The function of the staggered waterproof plates is to further play a waterproof role and prevent water from entering the space below them.

The processing tank 303 is installed on the first bracket 301, and all the multi-angle fine grinding mechanisms 302 are installed in the processing tank 303.
