[0022] Referring to Figures 1 to 6 , the following embodiments are made for the linear grooving and edge washing machine of the present invention: A linear grooving and edge washing machine includes: a circulating conveying device 10, a centering and correcting device 20, a grooving device 30, and an edge washing device 40.

[0023] The ceramic ware circulating conveying device 10 includes a rotating shaft mechanism 100 and a circulating driving mechanism 200. The number of the rotating shaft mechanisms 100 is multiple, and the circulating driving mechanism 200 is used to drive the multiple rotating shaft mechanisms 100 to move synchronously along a closed-loop path, and the multiple rotating shaft mechanisms 100 are arranged at equal intervals along the closed-loop path. The closed-loop path has at least one working section extending forward and backward.

[0024] The rotating shaft mechanism 100 extends vertically in the working section, and the upper end of the rotating shaft mechanism 100 has a material supporting portion 121 for supporting and carrying external materials.

[0025] The centering and correcting device 20, the grooving device 30, and the edge washing device 40 are arranged in sequence beside the working section. The centering and correcting device 20 includes a centering roller 21 and a correcting feeding driving member 22. The centering roller is rotatably arranged, and the centering roller 21 has a rotation axis 120 line extending vertically. The correcting feeding driving member 22 is used to drive the centering roller 21 to approach or move away from the working section. The grooving device 30 is provided with a grooving tool 31 for grooving processing, and the edge washing device 40 is provided with a rotatable edge washing wheel 41.

[0026] In actual use, the rotating shaft mechanism 100 is driven by the circulating driving mechanism 200 to move in a cycle along the closed-loop path. After the ceramic ware is loaded onto the rotating shaft mechanism 100 in the working section, it can move forward and backward along the working section. During the process of the ceramic ware moving along the working section, the correcting feeding driving member 22 can drive the centering roller to approach, and the centering and positioning of the ceramic ware are realized through the rotating centering roller, thereby improving the positioning accuracy of the ceramic ware to meet the accuracy requirements of grooving processing. After the ceramic ware is grooved by the grooving tool 31, it is polished and edge-washed by the edge washing wheel 41. The ceramic ware circulating conveying device of the present invention adopts a linear arrangement structure, occupies a small space, can match the in-line production, and is corrected and positioned by the centering and correcting device 20 before grooving processing, improving the positioning accuracy of the ceramic ware and ensuring the effect and quality of grooving processing.

[0027] In this embodiment, the closed-loop path forms a waist-shaped hole range in the left-right projection, that is, the upper and lower sides of the closed-loop path extend forward and backward, and the front and rear ends of the closed-loop path are in a circular arc transition. The working section is on the upper side of the closed-loop path, the rotating shaft mechanism 100 extends up and down in the working section, and the supporting portion 121 is arranged upward. When the rotating shaft mechanism 100 moves to the lower side of the closed-loop path, the supporting portion 121 flips to the downward direction. In some other embodiments, the closed-loop path is on a horizontal plane, and during the movement of the rotating shaft mechanism 100 along the closed-loop path, the supporting portion 121 of the rotating shaft mechanism 100 always remains arranged upward.

[0028] The rotating shaft mechanism 100 comprises: a rotating shaft base plate 110 and a rotating shaft 120. The rotating shaft 120 is rotatably mounted on the rotating shaft base plate 110, and the circulating driving mechanism 200 has a circulating driving end which is transmission-connected with the rotating shaft base plate 110 and enables the rotating shaft base plate 110 to move along the closed-loop path.

[0029] In this embodiment, the circulation drive mechanism 200 includes a chain transmission component 210 and a belt component 220. There are two chain transmission components 210, which are arranged on the left and right sides, and the belt component 220 is arranged between the two chain transmission components 210.

[0030] like Figure 3 As shown, the chain transmission component 210 includes a driving sprocket 211, a driven sprocket 212, a driving chain 213 and a circulating driving motor 214. The driving sprocket 211 and the driven sprocket 212 are arranged front and back, and the driving chain 213 is driven and wound around the driving sprocket 211 and the driven sprocket 212, so that the driving chain 213 forms the closed loop path. The output shaft of the circulating driving motor 214 is drivingly connected to the driving sprocket 211.

[0031] In this embodiment, the driving sprockets 211 of the two chain transmission components 210 are coaxially fixedly connected to each other, and the two driven sprockets 212 are coaxially fixedly connected to each other. The rotating shaft 120 is rotatably mounted on the middle part of the rotating shaft base plate 110, and the left and right ends of the rotating shaft base plate 110 are respectively fixedly connected to the driving chains 213 of the two chain transmission components 210. When the circulating driving motor 214 drives the driving sprocket 211 to rotate, the driving chain 213 moves along the closed loop path, thereby driving the rotating shaft base plate 110 to circulate along the closed loop path.

[0032] The upper section of the drive chain 213 extends in the front-rear direction to form the working section. A support bar is fixedly arranged on the lower side of the upper section of the drive chain 213. The support bar is arranged between the driving sprocket 211 and the driven sprocket 212. The support bar is strip-shaped and extends in the front-rear direction. The upper section of the drive chain 213 is arranged on the upper side of the support bar. The support bar supports the drive chain 213 between the driving sprocket 211 and the driven sprocket 212 to prevent the drive chain 213 from sagging.

[0033] As Figures 3 to 5 shown, the belt member 220 includes two belt pulleys 221 and a perforated belt 222. One of the belt pulleys 221 is coaxially and fixedly arranged between the two driving sprockets 211, and the other belt pulley 221 is coaxially and fixedly arranged between the two driven sprockets 212. The perforated belt 222 is wound around the two belt pulleys 221 in a transmission manner so that the perforated belt 222 extends along the closed-loop path. The rotating shaft substrate 110 is arranged outside the perforated belt 222. The perforated belt 222 is provided with a plurality of avoidance holes at equal intervals. The rotating shaft 120 passes through the avoidance holes. The perforated belt 222 extends along the closed-loop path and encloses a closed area. The outside of the perforated belt 222 refers to the side away from the closed area, and the side close to the closed area is the inside.

[0034] The belt pulley 221 is coaxially and fixedly connected to the driving sprocket 211 and the driven sprocket 212 respectively, so that the perforated belt 222 wound around the belt pulley 221 can move synchronously and circularly with the drive chain 213, preventing mud debris from falling into the circular drive mechanism 200 and affecting the rotation or circular movement of the rotating shaft mechanism 100.

[0035] Referring to the attached Figures 3 to 5 drawing, to improve the stability and positioning accuracy of the movement of the rotating shaft mechanism 100 in the working section, the ceramic ware circular conveying device 10 of this embodiment is provided with guide rods 300. The guide rods 300 extend in the front-rear direction. The two guide rods 300 are arranged on the left and right sides of the working section in the left-right direction. Guide wheels 111 are arranged at both the left and right ends of the rotating shaft substrate 110. The guide wheels 111 arranged at both ends of the rotating shaft substrate 110 are respectively in rolling contact with the two guide rods 300.

[0036] The rotation shaft substrate 110 is guided and limited in the front-rear direction by two guide rods 300, so as to prevent the rotation shaft substrate 110 from deflecting and displacing left and right within the working section, thereby improving the feeding and processing accuracy of the centering pulley 21, the grooving cutter 31, and the edge trimming wheel 41 in the left-right direction. Further, in order to prevent the rotation shaft substrate 110 from rotating and deflecting between the two guide rods 300, the number of guide wheels 111 at at least one end of the rotation shaft substrate 110 is multiple. In this embodiment, two guide wheels 111 arranged front and rear are rotatably provided at the left end of the rotation shaft substrate 110.

[0037] Refer to the attached Figure 4 , the guide rod 300 of this embodiment is in the shape of a long cylinder, and the outer edge of the guide wheel 111 is provided with an arc-shaped groove corresponding to the guide rod 300. The guide wheel 111 abuts against the cylindrical guide rod 300 through the arc-shaped groove, so that the rotation shaft substrate 110 can maintain a unified height position within the working section, further improving the machining positioning accuracy.

[0038] In order to prevent the ceramic utensil material from shifting under force during the processing, the rotating shaft mechanism 100 needs to fix the material thereon, and a suction attachment 140 for adsorbing the material is provided on the material supporting portion 121 of the rotating shaft 120. The rotation shaft substrate 110 is provided with a gas guide sleeve 130, the gas guide sleeve 130 is rotatably sleeved outside the rotating shaft 120, and an annular gas guide space is formed between the gas guide sleeve 130 and the rotating shaft 120. The rotating shaft 120 has a gas guide channel 122 communicating the gas guide space with the suction attachment 140, and the gas guide sleeve 130 has a gas guide port 131 communicating the gas guide space with the negative pressure generating element.

[0039] The upper end of the gas guide shaft sleeve is fixedly and sealedly connected to the rotating shaft 120, and the lower end of the gas guide shaft sleeve is rotatably and sealedly connected to the rotation shaft substrate 110, so that the upper and lower ends of the gas guide space are sealed and airtight. The gas guide port 131 extends radially, one end of the gas guide port 131 communicates with the gas guide space, and the other end is connected to the negative pressure generating element.

[0040] The gas guide channel 122 includes a first channel and a second channel that communicate with each other. The first channel extends along the axial direction of the rotating shaft 120, the upper end of the first channel communicates with the suction attachment 140, the lower end of the first channel communicates with the second channel, the second channel extends radially, and the second channel communicates the first channel and the gas guide space.

[0041] In this embodiment, the material supporting portion 121 is further provided with a frustum-shaped supporting platform 150. An annular sealing ring is provided on the upper side of the supporting platform 150. The adsorbing member 140 is disposed in the middle space of the supporting platform 150. The adsorbing member 140 is a vacuum chuck having a bellows structure. In the non-adsorbing state, the upper end of the adsorbing member 140 is higher than the annular sealing ring. In the adsorbing state, the adsorbing member 140 contracts and deforms, and its upper end moves downward so that the adsorbing surface of the material presses downward against the annular sealing ring.

[0042] To adapt to different ceramic ware products, the supporting platform 150 is detachably mounted on the upper end of the rotating shaft 120. When changing the product model or specification, different supporting platforms 150 and adsorbing members 140 can be replaced according to the size of the adsorbing surface of the ceramic ware, so as to improve the product matching degree and avoid the situation of product dropping.

[0043] During actual use, when the rotating shaft 120 rotates, the adsorbing member 140 can be communicated with the negative pressure space through the air guiding channel 122. The negative pressure generated by the negative pressure generating element can be transmitted to the adsorbing member 140 through the negative pressure space and the air guiding channel 122, so as to adsorb and fix the material at the upper end of the rotating shaft 120.

[0044] Since the rotating shaft mechanism 100 moves in a closed-loop path, to control the start and stop of the vacuum adsorption of the rotating shaft 120, the ceramic ware circulating conveying device 10 of this embodiment is provided with a negative pressure pipe 400. The on-off control of the air guiding port 131 and the negative pressure generating element is realized through the perforated belt 222 and the negative pressure pipe 400.

[0045] Specifically, the negative pressure pipe 400 is in a strip shape. The upper end of the negative pressure pipe 400 has a butting surface 410 extending in the front-rear direction. The butting surface 410 is provided with a communication groove 411 extending in the front-rear direction. The negative pressure pipe 400 is disposed in the working section. For the perforated belt 222 in the working section, the air guiding sleeve 130 is disposed outside the perforated belt 222, and the negative pressure pipe 400 is disposed inside the perforated belt 222. The perforated belt 222 is provided with communication holes 2221 penetrating through its belt surface. The number of the communication holes 2221 is the same as the number of the rotating shaft mechanisms 100. The plurality of communication holes 2221 are arranged at equal intervals on the perforated belt 222. The air guiding ports 131 of the rotating shaft mechanisms 100 are in one-to-one correspondence and communication with the communication holes 2221.

[0046] The abutting surface 410 abuts against the inner belt surface of the perforated belt 222, so that the inner belt surface of the perforated belt 222 can cover and seal the communication groove 411. The communication hole 2221 and the communication groove 411 are vertically aligned in the front-back direction projection. When the communication hole 2221 moves to the upper side of the communication groove 411, the communication hole 2221 and the communication groove 411 communicate with each other, so that the air guide port 131 is communicated with the communication groove 411.

[0047] During actual use, the length and position of the communication groove 411 are set according to the positions of the centering and correcting device 20, the grooving device 30, and the edge washing device 40, so that the rotating shaft mechanism 100 in the working section is not connected to the negative pressure during the centering and correcting process, so that the ceramic material can be position-corrected and adjusted at the material supporting part 121. After the centering and correcting of the rotating shaft mechanism 100 in the working section is completed, the negative pressure is connected to adsorb and fix the ceramic material on the material supporting part 121.

[0048] The ceramic appliance circulating and conveying device 10 further includes a self-rotation driving mechanism 500. The self-rotation driving mechanism 500 is used to drive the rotating shaft 120 to rotate relative to the rotating shaft substrate 110 around its own rotation axis 120.

[0049] In this embodiment, a self-rotation driven wheel 160 is provided at one end of the rotating shaft 120 away from the material supporting part 121, and the self-rotation driven wheel 160 is fixedly connected to the rotating shaft 120 coaxially. The self-rotation driving mechanism 500 includes a self-rotation transmission member 510 and a self-rotation driving member 520. The self-rotation transmission member 510 is provided with a self-rotation driving wheel 512 elastically arranged in the left-right direction. The self-rotation driving wheel 512 is elastically abutted and drivingly connected to the self-rotation driven wheel 160, and the self-rotation driving member 520 is used to drive the self-rotation driving wheel 512 to rotate.

[0050] Refer to the attached Figure 6 As shown, the self-rotation transmission member 510 includes a transmission shaft 511. The transmission shaft 511 is rotatably arranged through a rotating bearing 513. The axial direction of the transmission shaft 511 extends in the left-right direction. The self-rotation driving wheel 512 is arranged at one end of the transmission shaft 511 facing the rotating shaft mechanism 100, and the self-rotation driving wheel 512 is slidably connected to the transmission shaft 511 in the axial direction. A compression spring 514 is arranged between the self-rotation driving wheel 512 and the rotating bearing 513. The two ends of the compression spring 514 are elastically abutted against the self-rotation driving wheel 512 and the rotating bearing 513 respectively, so that the self-rotation driving wheel 512 has a tendency to move away from the rotating bearing 513 and close to the rotating shaft mechanism 100.

[0051] A spring pressure cover is provided between the compression spring 514 and the rotating bearing 513, the compression spring 514 abuts against one side of the spring pressure cover, and the other side of the spring pressure cover is rotatably connected to the rotating bearing 513 to prevent the compression spring 514 from getting stuck or damaged during rotation relative to the rotating bearing 513.

[0052] In the projection in the front-to-back direction, the self-rotation transmission component 510 of this embodiment is arranged on the right side of the rotating shaft mechanism 100, and the self-rotation driving wheel 512 is pressed against the self-rotation driven wheel 160 to the left. A limit pull plate 515 is adjustably provided at one end of the transmission shaft 511 facing the rotating shaft mechanism 100, and the self-rotation driving wheel 512 is arranged on the right side of the limit pull plate 515. Specifically, a limit pull rod is passed through the transmission shaft 511, and the limit pull plate 515 is coaxially threadedly sleeved on the limit pull rod. The limit pull rod provides a foundation for installation and position adjustment for the limit pull plate 515, and the limit pull plate 515 limits the limit position of the self-rotation driving wheel 512 to be elastically ejected to the left, so that the self-rotation transmission wheel can push open the self-rotation driving wheel 512 and abut against it when it moves to the corresponding position front and back.

[0053] Considering the speed and accuracy of being convenient to control the conveying, the self-rotation driving member 520 in the present embodiment adopts a servo motor. In other embodiments, the self-rotation driving member 520 can be a rotation driving element such as a stepping motor or a pneumatic motor. The right end of the transmission shaft 511 and the output end of the self-rotation driving member 520 are connected to each other through a belt transmission mechanism. In other embodiments, other transmission modes such as a coupling, a chain drive, a gear drive or a worm gear drive can also be adopted between the transmission shaft 511 and the self-rotation driving member 520.

[0054] Since the rotating shaft mechanism 100 does not need to rotate during the movement, but needs to rotate during the centering correction, grooving processing and edge washing processing. In this embodiment, the plurality of self-rotation transmission components 510 are arranged at equal intervals along the front-to-back direction, and the spacing between two adjacent self-rotation transmission components 510 is consistent with the spacing between two adjacent rotating shaft mechanisms 100. This allows the plurality of rotating shaft mechanisms 100 to be synchronously moved to be in transmission connection with each self-rotation transmission component in a one-to-one correspondence.

[0055] The centering correction device 20, the grooving device 30 and the edge washing device 40 of this embodiment are all double-station structures, and the centering rotary wheel 21, the grooving knife 31 and the edge washing wheel 41 are all arranged in pairs. The spacing between the centering rotary wheels 21 arranged in pairs is consistent with the spacing between the two adjacent rotating shaft mechanisms 100; similarly, the spacing between the grooving knife 31 and the edge washing wheel 41 arranged in pairs is consistent with the spacing between the two adjacent rotating shaft mechanisms 100. On this basis, in order to make the rotation speeds of the two rotating shaft mechanisms 100 in the same processing step consistent and save costs, every two adjacent self-rotating transmission components 510 are synchronously connected to each other and driven by the same self-rotating drive component.

[0056] The centering correction device 20 includes a correction slide 23, the centering rotary wheel 21 is adjustably arranged on the correction slide 23, and the correction feed drive component 22 drives the correction slide 23 to move left and right. Considering the convenience of controlling the speed and accuracy of rotation, the centering rotary wheel 21 in this embodiment is driven by a servo motor to achieve rotation. The correction feed drive component 22 can adopt a linear drive component such as a cylinder, an electric push rod, a hydraulic push rod or a screw nut drive assembly. The specific structure of the grooving device 30 and the edge washing device 40 can refer to the structure of the centering correction device 20, or refer to the existing grooving device 30 and the edge washing device 40, and no examples are given here.
