Description

Technical Field

[0001] This utility model relates to the technical field of sanitary ware production equipment, and in particular to a blank turning machine. Background Technology

[0002] For example, the manufacturing process of bathroom products such as split-type smart toilets and split-type conventional toilets involves grouting to obtain mud blanks and firing. During this process, it is also necessary to turn the mud blanks, which are in an inverted state, over. Currently, the turning of mud blanks is mostly done manually or semi-manually. However, since the mud blanks have not yet been fired, their overall strength is poor. Using the above-mentioned method to turn them over can easily cause the products to crack, increase the defect rate, and the turning efficiency is low, resulting in a long production cycle.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0026] This utility model provides a billet turning machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0027] Please see Figure 1 and Figure 7 This utility model provides a billet turning machine, including a frame 1, a turning drive mechanism 2 disposed on the frame 1, a turning frame 3 connected to the turning drive mechanism 2, a fixed conveying mechanism 4 and a lifting conveying mechanism 5 disposed on the turning frame 3, and a return plate conveying mechanism 6 disposed below the turning frame 3 and disposed on the frame 1; the fixed conveying mechanism 4 is used to support the product 10 to be turned; the lifting conveying mechanism 5 is used to clamp a first pallet 20, and can rise or fall along the height direction of the turning frame 3, so as to cooperate with the fixed conveying mechanism 4 to clamp the product 10 to be turned between the fixed conveying mechanism 4 and the first pallet 20; the return plate conveying mechanism 6 is used to return a second pallet conveyed from the downstream to the upstream of the billet turning machine.

[0028] In practical applications, the upstream of the billet turning machine is a lifting temporary storage conveyor platform. The initial state of the billet turning machine is as follows: the lifting conveyor mechanism 5 is located above the fixed conveyor mechanism 4, and the first pallet 20 is clamped on the lifting conveyor mechanism 5, while the second pallet is located on the return plate conveyor mechanism 6. The product 10 (toilet side down) conveyed from the upstream direction is temporarily stored on the lifting temporary storage conveyor platform. The product 10 is then conveyed to the fixed conveyor mechanism 4 via the lifting temporary storage conveyor platform. Subsequently, the lifting conveyor mechanism 5 moves downward, causing the first pallet 20 to move downward together until the lower surface of the first pallet 20 contacts the product 10, thus securing the product 10 firmly between the fixed conveyor mechanism 4 and the lifting conveyor mechanism 5. Next, the flipping drive mechanism 2 operates, causing the flipping frame 3 and the product 10 clamped between the fixed conveyor mechanism 4 and the lifting conveyor mechanism 5 to rotate synchronously by 180°, so that the fixed conveyor mechanism 4 is on top, the lifting conveyor mechanism 5 is on the bottom, and the toilet side of the product 10 is facing upward, completing the flipping of the product 10. Simultaneously, the lifting temporary conveyor platform descends to the same height as the return conveyor mechanism 6. Under the action of the return conveyor mechanism 6, the second pallet located downstream is conveyed to the lifting temporary conveyor platform located upstream. Next, the lifting conveyor mechanism 5 moves downwards with the first pallet 20 and the flipped product 10, bringing the lifting conveyor mechanism 5 to the same height as the conveyor line downstream of the turning machine, and conveying the first pallet 20 along with the product 10 downstream. Then, the second pallet located upstream of the turning machine, i.e., on the lifting temporary conveyor platform, is conveyed downstream (towards the turning machine), placing it on the lifting conveyor mechanism 5 and clamping it in place. Subsequently, the turning drive mechanism 2 operates again, causing the turning frame 3 to rotate 180°, returning all mechanisms of the turning machine to their initial state, ready to turn the next product 10.

[0029] The aforementioned turning machine uses a fixed conveying mechanism 4 and a lifting conveying mechanism 5 to clamp and fix the product 10 and transport it downstream. The turning drive mechanism 2 drives the turning frame 3 to turn, so that the fixed conveying mechanism 4, the lifting conveying mechanism 5 and the product 10 clamped between them are turned synchronously. The entire turning process of the clay blank does not require manual intervention, which can ensure the high quality of the product 10 and improve the turning efficiency.

[0030] Please see Figure 2 and Figure 3In some embodiments, the lifting and conveying mechanism 5 includes a lifting and conveying frame 51, a lifting drive member 52 disposed on the lifting and conveying frame 51, multiple lifting and conveying rollers 53 extending laterally and rotatably disposed on the lifting and conveying frame 51, a lifting synchronous belt (not shown in the figure) wound around the multiple lifting and conveying rollers 53, and also involves a power source for driving the multiple lifting and conveying rollers 53 to rotate, which is conventional technology and will not be described in detail), and multiple first pallet clamping cylinders 54 disposed on both sides of the lifting and conveying frame 51; the lifting drive member 52 is used to drive the lifting and conveying frame 51 to rise or fall along the height direction of the tilting frame 3; multiple first clearance holes corresponding to the first pallet clamping cylinders 54 are opened on both sides of the lifting and conveying frame 51, the extension direction of the output end of the multiple first pallet clamping cylinders 54 is parallel to the extension direction of the lifting and conveying rollers 53, and the output end of the multiple first pallet clamping cylinders 54 is used to pass through the corresponding first clearance hole and abut against the side wall corresponding to the first pallet 20. Specifically, under the action of the lifting drive component 52, the lifting conveyor frame 51 and the various mechanisms mounted on the lifting conveyor frame 51 can rise or fall along the height direction of the tilting frame 3, thereby realizing the rise or fall of the product 10. At the same time, by utilizing the extension of the output end of the first pallet clamping cylinder 54, the output end of the first pallet clamping cylinder 54 passes through the first clearance hole, and achieves a stable clamping of the first pallet 20, preventing the first pallet 20 from falling off during the tilting process.

[0031] Please see Figure 2 and Figure 4 In some embodiments, the lifting drive component 52 includes a lifting drive motor 521, a lifting reducer 522 connected to the output end of the lifting drive motor 521, a lifting drive shaft 523 connected to the output end of the lifting reducer 522 and extending laterally, two lifting bearing seats 524 disposed on the lifting conveyor frame 51, two lifting gears 525 disposed at the end of the lifting drive shaft 523, and a lifting rack 526 disposed on the two inner side walls of the tilting frame 3 and extending vertically; the lifting gears 525 mesh with the corresponding lifting racks 526; the end of the lifting drive shaft 523 is rotatably connected to the corresponding lifting bearing seat 524. The rotation of the lifting drive motor 521 drives the lifting drive shaft 523 and the lifting gears 525 to rotate, and under the guidance of the lifting racks 526, the lifting conveyor frame 51 rises or falls. The gear and rack meshing transmission method provides high precision and smooth movement.

[0032] Please see Figure 4In some embodiments, lifting slide rails 31 are respectively provided in the front and rear directions of the lifting rack 526, and lifting sliders 32 are provided on the left and right side walls of the lifting conveyor frame 51. The lifting sliders 32 are slidably connected to the corresponding lifting slide rails 31; and each lifting slide rail 31 has a limit block 33 at its end, and the lifting slider 32 moves between two limit blocks 33. The cooperation of the lifting slide rails 31 and the lifting sliders 32 further improves the smoothness of the movement of the lifting conveyor frame 51. Specifically, the movement stroke of the lifting slider 32 can be limited by setting a sensor and a limit switch. The limit block 33 is set to the maximum movement stroke of the lifting slider 32. The setting of the limit block 33 can avoid collision problems caused by the lifting conveyor frame 51 deviating from the set movement trajectory when the lifting drive motor 521 malfunctions and continues to run.

[0033] Please see Figure 2 and Figure 3 In some embodiments, the lifting conveyor frame 51 is further provided with a blocking mounting plate 551, on which a blocking cylinder 552 is mounted, and a baffle 553, the output end of which passes through the upper and lower side walls of the blocking mounting plate 551 and is located on the output end of the blocking cylinder 552. The baffle 553 extends laterally, and the output end of the blocking cylinder 552 is used to drive the baffle 553 to pass between the two lifting conveyor rollers 53. When the lifting conveyor mechanism 5 flips to be located below the fixed conveyor mechanism 4, waiting to support the second pallet, the baffle 553 is located downstream. The operation of the blocking cylinder 552 drives the baffle 553 to rise from the gap between the lifting conveyor rollers 53, so as to limit the front end of the second pallet. The output end of the blocking cylinder 552 retracts, causing the baffle 553 to be submerged in the gap between the lifting conveyor rollers 53, so as to allow the second pallet to pass through.

[0034] Please see Figure 2 In some embodiments, the blocking mounting plate 551 is further provided with blocking sleeves 554 located on the left and right sides of the blocking cylinder 552. A blocking guide rod 555 is fitted into each blocking sleeve 554, and the end of the blocking guide rod 555 is fixedly connected to the baffle 553. This arrangement is used to improve the smoothness of the movement of the baffle 553 when it rises or falls.

[0035] Please see Figure 5In some embodiments, the fixed conveying mechanism 4 includes two fixed frames 41 fixedly mounted on the flipping frame 3 and symmetrically arranged on both sides, multiple horizontally extending fixed conveying rollers 42 rotatably arranged between the two fixed frames 41, a fixed synchronous belt (not shown in the figure, but also involving a power source for driving the multiple fixed conveying rollers 42 to rotate, which is conventional technology and will not be described in detail), and multiple second clamping cylinders 43 arranged on the two fixed frames 41; the multiple fixed conveying rollers 42 are all used to support the toilet seat of the product 10 and to convey the product 10 downstream; each of the two fixed frames 41 has multiple second clearance holes corresponding to the second clamping cylinders 43, the extension direction of the output end of the multiple second clamping cylinders 43 is parallel to the extension direction of the fixed conveying rollers 42, and the output end of the multiple second clamping cylinders 43 is used to pass through the corresponding second clearance hole and abut against the corresponding side wall of the product 10. When the multiple fixed conveying rollers 42 rotate, the product 10 can be conveyed. When it is necessary to clamp and fix the product 10, the output end of the second clamping cylinder 43 is used to pass through the second clearance hole.

[0036] Please see Figure 5 In some embodiments, the fixed frame 41 is also provided with two first conveying position limit switches 44 arranged in a front-to-back manner. When both first conveying position limit switches 44 are triggered by the product 10, it indicates that the product 10 has been conveyed to the set position. The corresponding mechanism can then be controlled to run or stop through the control mechanism to improve the automation level of the billet turning machine.

[0037] Please see Figure 6 In some embodiments, the return plate conveying mechanism 6 includes two fixed beams 61 fixedly mounted on the frame 1 and symmetrically arranged on both sides, multiple transversely extending return plate conveying rollers 62 rotatably arranged between the two fixed beams 61, and a return plate timing belt (the return plate timing belt and drive source are prior art) wound around the multiple return plate conveying rollers 62; two second conveying position limit switches 63 arranged front and rear are also provided on the fixed beams 61. The rotation of the return plate conveying rollers 62 is used to transport the second pallet upstream. The second conveying position limit switches 63 are used to sense the position status of the second pallet.

[0038] Please see Figure 1In some embodiments, the flipping drive mechanism 2 includes a flipping motor 21 mounted on the frame 1, a flipping bearing mounted on the frame 1, and a flipping bearing flange 22 rotatably connected to the flipping bearing and mounted on the flipping frame 3. The output end of the flipping motor 21 is fixedly connected to one side wall of the flipping frame 3, and the flipping bearing flange 22 is located on the opposite side of the flipping motor 21. The flipping motor 21 provides flipping power to the flipping frame 3, enabling the flipping frame 3 to rotate around the flipping bearing flange 22 and the flipping bearing.

[0039] In summary, this utility model utilizes a fixed conveying mechanism 4 and a lifting conveying mechanism 5 to clamp and fix the product 10 and transport it downstream. The flipping drive mechanism 2 drives the flipping frame 3 to flip, so that the fixed conveying mechanism 4, the lifting conveying mechanism 5 and the product 10 clamped between them are flipped synchronously. The entire flipping process of the clay blank does not require manual intervention, which can ensure the high quality of the product 10 and improve the flipping efficiency.
