[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent. Example 1

[0034] like Figure 1 As shown, the present invention provides a ceramic product trimming production line, comprising a feeding conveyor 100, a trimming device 200, and a discharging conveyor 300.

[0035] Among them, such as Figure 2 As shown, the feeding and conveying device 100 includes a conveyor frame 101, two support chains 102 mounted on the conveyor frame via sprocket assemblies, multiple support frames 103 evenly distributed on the support chains, and a drive mechanism 104 for driving the chains to rotate. The drive mechanism 104 is a motor drive mechanism. During operation, the drive mechanism 104 drives the chains to rotate, which in turn drives the support frames 103 to move and convey the ceramic blanks.

[0036] like Figure 3As shown, the support frame 103 includes two connecting crossbars 1031 and two support rods 1032. The two crossbars 1031 are spaced apart, and their two ends are fixedly connected to two support chains 102 by connectors 1033. The two support rods 1032 are spaced apart, and the two ends of each support rod 1031 are fixedly connected to the two crossbars 1032.

[0037] In this embodiment, the feeding conveyor 100 and the discharging conveyor 300 adopt the same structure, and the structure of the discharging conveyor 300 will not be described in detail here. In addition, sensors are installed at the ends of the feeding and discharging conveyors to monitor whether the ceramic blank has been removed. Thus, during the conveying of ceramic blanks, an intermittent conveying method can be adopted. That is, the sensor monitors the process, and when there is a ceramic blank on the support frame at the outlet end, the conveying stops; when a ceramic blank is removed, the device is activated to continue conveying one ceramic blank to the outlet end, ensuring normal continuous operation.

[0038] like Figure 1 , 4 As shown, the trimming device 200 includes a trimming frame 201, a billet transfer mechanism, and a trimming support 203. In practical applications, the trimming frame can be divided into two areas: a trimming area and a water supply area, depending on actual needs. The trimming area can be enclosed to form a trimming chamber 2010, which can centrally treat trimming dust and prevent dust from flying around and affecting the production area environment. The feeding conveyor 100 is located on the feeding side of the trimming frame 201; the discharging conveyor 300 is located on the discharging side of the trimming frame 201.

[0039] A guide rail 2011 is provided on the trimming frame 201, and the trimming support 203 can slide on the guide rail 2011. Two sets of blank transfer mechanisms are provided, respectively located on one side of the feeding and discharging points of the trimming frame 201. The blank transfer mechanism at the feeding point can transfer ceramic blanks from the feeding conveyor 100 to the trimming support 203, and the blank transfer mechanism at the discharging point can transfer ceramic blanks from the trimming support 203 to the discharging conveyor 300. During production, the ceramic blanks are transferred from the feeding conveyor 100 to the trimming chamber for inspection and trimming, then transferred to the watering area for watering; finally, they are transferred to the discharging conveyor 300.

[0040] In this embodiment, the billet transfer mechanism is an automatic handling mechanism 400, the specific structure of which is as follows: Figure 6As shown. The automatic conveying mechanism 400 includes a frame (not shown), a base mounting frame 42, a conveying support 44, a support rotation and lifting assembly 45, a conveying fork arm 46, and a fork arm telescopic drive assembly 47. The base mounting frame 42 is mounted on the frame, and the support rotation and lifting assembly 45 is mounted on the base mounting frame 42. The support rotation and lifting assembly 45 can drive the conveying support to rotate, and drive the conveying support to rise or fall. The conveying fork arm 46 is movably mounted on the conveying support 44, and the fork arm telescopic drive assembly 47 can drive the conveying fork arm 46 to extend or retract. Thus, when the conveying device is aligned with the trimming frame (e.g. Figure 2 As shown, the ceramic blank can be transferred between the two by controlling the extension, lifting, and rotation of the conveying fork arm 46 through the automatic conveying mechanism 400.

[0041] In actual production, due to space constraints, the conveying device and the trimming frame may be misaligned (e.g.) Figure 1 As shown in the figure, in this case, a moving track 41 can be installed on the frame. Specifically, as shown... Figure 7 As shown, multiple movable wheels 422 are also installed on the base mounting frame 42 and placed within the moving track. The movable wheels on both sides are connected by a drive shaft 421. A translation drive assembly for driving the movable wheels to rotate is installed on the base mounting frame 42. The base frame translation drive assembly 43 includes a translation drive motor 431 mounted on the base frame body, a drive sprocket mounted on the output shaft of the translation drive motor, and a driven sprocket mounted on the drive shaft 421. The drive sprocket and the driven sprocket are connected by a chain 432. The translation drive motor drives the drive shaft 421 and the movable wheels 422 to rotate, thereby causing the base mounting frame 42 to move along the moving track. In practical applications, limit switches or sensors can be set on the moving track according to the actual situation to ensure that the base mounting frame 42 moves to the accurate position.

[0042] like Figure 8As shown, the support rotation and lifting assembly 45 includes a lifting frame 451, a vertical rotating shaft 452 mounted on the lifting frame via a bearing seat, a rotating gear 453 fixed to the upper end of the vertical rotating shaft, a rotating drive motor 454 mounted on the lifting frame 451, a drive gear 455 mounted on the output shaft of the rotating drive motor and meshing with the rotating gear, multiple slide rails 456 mounted on the lifting frame, a limiting block 457 mounted on the bottom mounting frame and cooperating with the slide rails, a lifting drive motor 458 mounted on the bottom mounting frame, and an eccentric wheel 459 mounted on the bottom mounting frame via a rotating shaft. A lifting wheel 450 is also mounted on the lifting frame 451, and the lifting wheel 450 contacts the wheel surface of the eccentric wheel 459. The output shaft of the lifting drive motor 458 is connected to the rotating shaft for transmission. When the lifting drive motor 458 is working, it can drive the rotating shaft and the eccentric wheel 459 to rotate, thereby driving the lifting frame 451 to rise or fall. The transport support 44 is fixedly connected to the rotating gear 453 by screws. When the rotation drive motor 454 is working, it drives the rotating gear 453 through the drive gear 455, thereby driving the transport support 44 to rotate. In addition, limit switches or sensors can be set according to actual conditions to determine whether the transport support 44 has rotated to the correct position, so as to ensure that it rotates to the accurate position.

[0043] The transport support 44 is provided with a movable guide groove 441; the transport fork arm 46 includes a movable base plate 461 and a fork arm 462 mounted on the movable base plate, and a movable wheel 463 is provided on the movable base plate 462, which is disposed in the movable guide groove 441. The fork arm telescopic drive assembly 47 includes a telescopic drive motor 471 mounted on the movable base plate 461, and a drive gear 472 is connected to the output shaft of the telescopic drive motor. The transport support 44 is equipped with a rack 473 that meshes with the drive gear; the telescopic drive motor 471 can drive the movable base plate 461 to move along the movable guide groove 441.

[0044] like Figure 9 As shown, a protective cover 48 is also connected to the base mounting frame 42 of the automatic conveying mechanism 400. By setting the protective cover to cover the base mounting frame 42 and related components, dust and collision prevention can be achieved, reducing later maintenance and extending service life.

[0045] like Figure 10 , 11 As shown, the trimming support 203 includes a sliding bracket 2031 and a rotary table 2032 mounted on the sliding bracket. The sliding bracket 2031 is provided with sliding wheels 2033 that cooperate with the guide rail 2011. When the sliding bracket 2031 is pushed, it can move along the guide rail 2011 on the trimming machine frame. Specifically, the rotary table 2032 is mounted on the sliding bracket 2031 via a rotating shaft 2034 and a bearing assembly 2035. During production, the ceramic blank is placed on the rotary table and can be rotated, facilitating operations such as blank inspection and trimming.

[0046] The following is based on Figure 1 The following describes the working process of a ceramic product trimming production line with the layout shown (the conveying device and trimming device frames are staggered). During production, the ceramic blanks are first conveyed by the feeding conveyor 100. When a ceramic blank is detected at the outlet of the feeding device, the operation automatically stops. The operator pre-places the trimming support 203 at the feeding end of the trimming frame. After confirming that the trimming support 203 is placed at the feeding end of the trimming frame, the automatic conveying mechanism 400 moves to the position corresponding to the outlet end of the feeding device 100, extends the fork arm 462 to lift the ceramic blank from the support frame 103 of the feeding conveyor, then retracts the fork arm and moves to the corresponding position on the trimming frame, drives the conveying support to rotate, rotates 180° and then extends the fork arm 462 to deliver the ceramic blank to the trimming support 203 at the feeding end of the trimming frame, and drives the conveying support to descend, placing the ceramic blank on the trimming support 203 pre-placed by the operator. After completion, the fork arm resets, waiting for the next conveying. Next, the operator can push the trimming support 203 with the ceramic blank to a suitable position to perform operations such as checking and trimming the blank. After the operator completes the operation on the ceramic blank, the trimming support with the ceramic blank is pushed to the discharge point, where the automatic conveying mechanism sends the blank to the discharge conveyor 300 for the next process.

[0047] Furthermore, by setting up a moving track in conjunction with a sliding track, in practical applications, an automatic conveying mechanism can be installed at the inlet and outlet of two or more trimming devices, such as... Figure 12 As shown, by using an automatic conveying mechanism to move back and forth, it is possible to serve two or more sets of blank trimming devices simultaneously. Example 2

[0048] The technical difference between this embodiment and embodiment one is that the billet transfer mechanism 202 of the billet trimming device 200 adopts a manual handling mechanism, and the specific scheme is as follows.

[0049] like Figure 13 , 14 As shown, the trimming device 200 includes a trimming frame 201, a blank transfer mechanism 202, and a trimming support 203. A guide rail 2011 is provided on the trimming frame 201, and the trimming support 203 can slide on the guide rail 2011. Two sets of the blank transfer mechanism 202 are provided, respectively located at the feeding and discharging points of the trimming frame 201. The blank transfer mechanism at the feeding point can transfer ceramic blanks from the feeding conveyor 100 to the trimming support 203, and the blank transfer mechanism at the discharging point can transfer ceramic blanks from the trimming support 203 to the discharging conveyor 300.

[0050] Specifically, such as Figure 15 ,16 The blank transfer mechanism 202 includes a sliding seat 25 and a liftable fork assembly mounted on the sliding seat. The liftable fork assembly includes two lifting plates 21 respectively mounted on both sides of the sliding seat, a fork rod 22 fixed on each lifting plate, and a cam lifting mechanism 23 mounted on the sliding seat for driving the lifting plates to move up and down. The lifting plates are provided with guide grooves 211, and a limiting screw assembly 24 passing through the guide groove is mounted on the sliding seat 25.

[0051] Specifically, the sliding seat 25 includes a U-shaped seat body 251, a roller assembly 252 mounted on the seat body, and outer cover plates 253 mounted on both sides of the seat body 251. The sliding seat 25 is mounted on the guide rail 2011 via the roller assembly 252. Pushing the sliding seat 25 allows the roller assembly 252 to slide on the guide rail 2011. The outer cover plates 253 and the seat body 251 directly form the installation space for the lifting plate 21.

[0052] The cam lifting mechanism 23 includes a rotating shaft 231 mounted on a sliding seat. A cam 232 is mounted at each end of the rotating shaft 231. A roller 212 is fixedly connected to the lifting plate 21. The roller 212 contacts the circumferential side of the cam 232. A limiting groove 233 is provided on the cam 232. A handle 234 is mounted at one end of the rotating shaft. When the handle 234 is driven to rotate, it can drive the cam 232 to rotate, thereby driving the roller 212 and the lifting plate 21 to move up and down. When the lifting plate 21 rises to the high position, the roller 212 falls into the limiting groove 233. Preferably, a limiting baffle 235 is also installed on the sliding seat. The cam 232 is fan-shaped, and the limiting baffle 235 is inverted V-shaped. When the lifting plate 21 rises to the high position, the side of the cam 232 contacts one side of the limiting baffle 235. When the lifting plate 21 falls to the low position, the side of the cam 232 contacts the other side of the limiting baffle 235, thus playing a limiting role.

[0053] The limiting screw assembly 24 includes two limiting plates 241 and three limiting screws 242 (upper, middle, and lower). The two limiting plates are spaced apart, and the lifting plate is positioned between the two limiting plates 241. During assembly, each limiting screw 242 passes sequentially through the side wall of the sliding seat and the first limiting plate 241. A bearing assembly 243 is then installed on the limiting screw 242. After completion, the limiting screw 242 passes through the guide groove 211 of the lifting plate, and the bearing assembly 243 is placed within the guide groove 211. Finally, it is fixedly connected to the second limiting plate 241. The lifting plate can move up and down between the two limiting plates 241.

[0054] like Figure 13The ceramic product trimming production line shown in the diagram first transports the ceramic blanks through the feeding conveyor 100. Operation automatically pauses when a ceramic blank is detected on the support frame at the outlet of the feeding device. The operator pre-places the trimming support 203 at the feeding end of the trimming frame; then, they push the sliding seat 25 of the blank transfer mechanism 202 towards the feeding conveyor, causing the fork 22 to insert below the bottom surface of the ceramic blank. The drive handle 234 then lifts the lifting plate 21 and fork 22, raising the ceramic blank. The sliding seat 25 is then pulled away from the feeding conveyor until the ceramic blank is above the trimming support 203. Rotating the drive handle controls the lifting plate and fork of the adjustable fork assembly to move downwards, allowing the ceramic blank to fall onto the trimming support 203. The operator then performs checks and trimming operations on the ceramic blank. After completing this process, the blank-repairing support with the ceramic blank is pushed to the blank transfer mechanism at the discharge point, and then sent out by the blank transfer mechanism to the discharge conveyor 300.

[0055] In addition, to better achieve assembly line operations, when multiple ceramic product trimming production lines are set up side by side, such as Figure 17 As shown, an automatic conveying mechanism can be installed at the outlet end of multiple discharge conveying devices 300. The automatic conveying mechanism can adopt the structure disclosed in Embodiment 1, which will not be described in detail here. The automatic conveying mechanism can transfer the ceramic blanks at the outlet end of multiple discharge conveying devices 300 to the main conveying line of the next process, and transport them to the next process in a unified manner.

However, these descriptions should not be construed as limiting the scope of the present utility model. The scope of protection of the present utility model is defined by the appended claims.
