Description

Technical Field

[0001] This utility model relates to the field of craft ceramics technology, specifically to a packaging machine for craft ceramics production. Background Technology

[0002] Pottery refers to vessels made from clay, while porcelain refers to vessels made from porcelain clay. Pottery is a general term encompassing pottery, stoneware, and porcelain. In ancient times, ceramics were called "ou," and any object made from clay (both types of clay) through processes such as mixing, shaping, drying, and firing can be called ceramic. With national economic development, cultural export, and the influence of artistic products, many foreigners have developed a fondness for ceramics. Ceramics can be used not only as ornamental items but also in daily life, thus requiring packaging during the production process.

[0003] A search revealed a prior art packaging device for process ceramics production (publication number: CN211336563U), which describes a device as follows: "The surface of the packaging plate has a moving groove, a packaging box is placed on the surface of the packaging plate, a placement groove is formed on the surface of the packaging box, an output plate groove is formed on the top of the packaging plate, a sealing frame is provided on one side of the output plate groove, a first telescopic pump is provided on the top of the sealing frame, a groove is formed on the inner surface of the sealing frame, a leakage groove is formed on the other end of the packaging plate, and a second telescopic pump is provided on the other end of the packaging plate." This device utilizes a packaging frame, a second telescopic pump, and a first telescopic rod. The push hole, fixed column, and sealing plate facilitate packaging of ceramics after production. The telescopic device pushes the packaging box into the output plate slot, and the second telescopic pump pushes the first telescopic rod and push hole, thereby pushing the sealing plate on the packaging frame outward to seal the ceramics inside the packaging box, increasing the convenience of the pushing process. However, the device does not have a corresponding buffer protection structure for the ceramics. Due to the fragile nature of ceramics, the packaged ceramics are easily broken due to vibration during handling or when the transport vehicle travels on bumpy roads, making the ceramics prone to breakage and loss during transportation and transfer.

Detailed Implementation

[0018] Reference Figures 1 to 4As shown, this utility model provides a packaging machine for the production of process ceramics, including: a workbench 1, with a main mounting frame 18 and a secondary mounting frame 9 fixedly connected to both ends of the upper surface of the workbench 1, and a transmission groove opened in the middle of the workbench 1, with a conveying assembly 8 fixedly connected in the transmission groove. A main partition plate 2 is fixedly connected in the main mounting frame 18, and a main push plate 17 is slidably connected to the upper surface of the main partition plate 2 via an electric rod 16. A box cover 3 is slidably connected to the feed inlet opened on the upper surface of the main mounting frame 18. Meanwhile, a secondary partition plate 14 is fixedly connected in the secondary mounting frame 9, and a secondary push plate 13 is slidably connected to the upper surface of the secondary partition plate 14 via an electric rod 25. A buffer layer 12 is slidably connected to the feed inlet opened on the upper surface of the secondary mounting frame 9. A secondary baffle 10 is fixedly connected to the top of the inner cavity of the secondary mounting frame 9 away from the electric rod 25. The packaging box 5 is slidably connected to the surface of the workbench 1 via the conveying assembly 8. An output plate 23 is connected to the side of the main mounting frame 18, and an input plate 24 is connected to the side of the secondary mounting frame 9.

[0019] In this embodiment, the packaging box 5 is fed into the sub-mounting frame 9 through the inner cavity of the input plate 24. First, the switch of the electric lever 2 15 is activated. The telescopic rod of the electric lever 2 15 pushes the buffer layer 12 placed on the upper surface of the sub-divider plate 14 through the sub-push plate 13. During the movement of the buffer layer 12, the main body of the sub-divider plate 14 will simultaneously block the feed port of the sub-mounting frame 9. Thus, when the buffer layer 12 moves directly above the packaging box 5, it can prevent the buffer layer 12 accumulated in the feed port of the sub-mounting frame 9 from sliding onto the surface of the sub-divider plate 14, ensuring that the sub-push plate can be smoothly reset. Then, the sub-vertical electric lever is activated. The switch of lever 21 and the telescopic rod of the secondary vertical electric lever 21 can assist in pushing the buffer layer 12 downward, thereby ensuring that the buffer layer 12 can be smoothly filled into the packaging box 5. After activating the reset switch of electric lever 25 and secondary vertical electric lever 21, the switch of conveyor assembly 8 is activated. The conveyor belt of conveyor assembly 8 pushes the packaging box 5 along the surface of the workbench 1 at a low speed into the main mounting frame 18 via the push rod. When the packaging box 5 just leaves the secondary mounting frame 9, the worker can fill the craft ceramics into the grooves opened in the buffer groove, enhancing the safety of the craft ceramics placed inside the packaging box 5. After that, start The switch of the electric lever 16 causes its telescopic rod to push the box cover 3 to move synchronously via the main push plate 17. The main body of the main push plate 17 simultaneously blocks the feed inlet of the main mounting frame 18, preventing the box cover 3 stacked inside the feed inlet of the main mounting frame 18 from accidentally falling onto the surface of the main partition plate 2. This ensures that the main push plate 17 can smoothly reset. The end of the box cover 3 detached from the main partition plate 2 will tilt downwards under gravity and abut against the upper surface of the packaging box 5. Subsequently, during the subsequent movement, the box cover 3 will first push the buffer plate 7 to move, and the buffer plate 7 will stretch the spring sleeved on the guide rod 20. When the other end of the lid 3 also detaches from the main partition plate 2, the buffer plate 7 will reset under the action of the tension spring. Then, the buffer plate 7 can perform corresponding position correction on the lid 3, so that the lid 3 can smoothly cover the upper surface of the packaging box 5 and the buffer layer 12. When the switch of the main vertical electric rod 19 is activated, the telescopic rod of the main vertical electric rod 19 can push the lid 3 down, thereby enhancing the stability of the connection between the lid 3 and the packaging box 5. When the switch of the side electric rod 6 is activated, the telescopic rod of the side electric rod 6 can push the packaging box 5 to move into the inner cavity of the output plate 23, thereby outputting the packaged process ceramics.

[0020] In a preferred embodiment, a buffer groove is provided at the top of the inner cavity of the main mounting bracket 18 near the end of the secondary mounting bracket 9. The buffer groove has a rectangular structure, and the guide rod 20 fixedly connected inside the buffer groove has a cylindrical structure. A spring is sleeved on the surface of the guide rod 20. Meanwhile, the buffer plate 7 has a convex structure. The protrusion at the upper end of the buffer plate 7 is slidably connected to the guide rod 20 through a through hole, and the two ends of the spring are fixedly connected to the surface of the buffer plate 7 and the end face of the buffer groove, respectively.

[0021] In this embodiment, as Figure 1 and Figure 2 The size of the protrusion of the buffer plate 7 and the buffer groove are matched, which can help enhance the stability of the buffer plate 7 when it moves. The spring sleeved on the surface of the guide rod 20 allows the buffer plate 7 to automatically reset after the box cover 3 is pushed away from the main push plate 17 after the box cover 3 is pushed. During the reset process, the buffer plate 7 can also perform corresponding auxiliary positioning of the box cover 3 to ensure that the box cover 3 can be smoothly sleeved on the upper surface of the packaging box 5.

[0022] In a preferred embodiment, the top of the inner cavity of the main mounting bracket 18 is fixedly connected to the main vertical electric rod 19 through the main storage groove, and the side of the inner cavity of the main mounting bracket 18 is provided with a receiving groove corresponding to the position of the output plate 23. The side electric rod 6 is fixedly connected in the receiving groove, and the main partition plate 2 fixedly connected in the main mounting bracket 18 has a rectangular structure, and the electric rod 16 is fixedly connected to the upper surface of the main partition plate 2.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The main vertical electric rod 19 helps to enhance the stability of the connection between the packaging box 5 and the lid 3, ensuring the sealing and protection effect of the packaging box 5 on the ceramic. The side electric rod 6 enables the ceramic to be automatically output from the inner cavity of the output plate 23 after packaging.

[0024] In a preferred embodiment, the end face of the main partition plate 2 is U-shaped, while the end face of the main push plate 17 is L-shaped. The upper surface of the main body of the main push plate 17 is attached to the top of the inner cavity of the main mounting bracket 18, and the distance between the main partition plate 2 and the top of the inner cavity of the main mounting bracket 18 is adapted to the thickness of the cover 3.

[0025] In this embodiment, as Figure 1 and Figure 2 The inner cavity of the main partition plate 2 is adapted to the size of the box cover 3, which can help enhance the stability of the box cover 3 when it moves. Furthermore, the structure of the main push plate 17 allows it to simultaneously block the inlet of the main mounting frame 18 when it pushes the box cover 3 away from the bottom of the inlet of the main mounting frame 18, thereby preventing the stacked box covers 3 in the inlet from blocking the reset path of the main push plate 17.

[0026] As a preferred embodiment, the end face of the sub-mounting bracket 9 has a U-shaped structure, the cross section of the inner cavity of the sub-mounting bracket 9 has a convex shape, and two sets of limiting plates 11 are symmetrically connected to the top of both sides of the inner cavity of the sub-mounting bracket 9. Both sets of limiting plates 11 have an E-shaped structure, and the outer side of the buffer layer 12 is provided with a limiting groove corresponding to the position of the protrusion of the limiting plate 11.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The setting of the limiting plate 11 and the limiting groove ensures that the buffer layer 12 will not fall accidentally if it does not move to the top of the packaging box 5. This helps to reduce the difficulty of filling the buffer layer 12 into the packaging box 5. The setting of the buffer layer 12 enables the ceramic art to have a corresponding buffering and protective effect inside the packaging box 5, reducing the chance of accidental damage to the ceramic art.

[0028] In a preferred embodiment, the top of the inner cavity of the secondary mounting bracket 9 is fixedly connected to the secondary vertical electric rod 21 via the secondary storage groove. The secondary partition plate 14 fixedly connected inside the secondary mounting bracket 9 has an L-shaped cross-section, and the bent part of the secondary partition plate 14 has a through-hole corresponding to the position of the transmission groove opening. At the same time, the electric rod 15 is fixedly connected to the upper surface of the secondary partition plate 14. The secondary push plate 13 has an L-shaped cross-section, and the upper surface of the secondary push plate 13 fits the top of the inner cavity of the secondary mounting bracket 9. The distance between the secondary partition plate 14 and the top of the inner cavity of the secondary mounting bracket 9 is adapted to the thickness of the buffer layer 12.

[0029] In this embodiment, as Figure 1 and Figure 3 The sub-baffle 10 fixedly connected inside the sub-mounting bracket 9 can help limit the movement range of the buffer layer 12, ensuring that the buffer layer 12 can be smoothly suspended above the packaging box 5. The structure of the sub-push plate 13 allows the sub-push plate 13 to push the buffer layer 12 away from the feed port of the sub-mounting bracket 9, and simultaneously block the feed port of the sub-mounting bracket 9, preventing the buffer layer 12 stacked in the feed port from sliding down to the surface of the sub-divider plate 14 and blocking the reset path of the sub-push plate 13.

[0030] In a preferred embodiment, a main guide plate 4 and a secondary guide plate 22 are fixedly connected to both sides of the upper surface of the workbench 1, respectively. The main guide plate 4 has an L-shaped structure, and the bent part of the main guide plate 4 is fixedly connected to the inside of the main mounting frame 18. The secondary guide plate 22 has a long strip structure, and the end faces of both ends of the secondary guide plate 22 are inclined. At the same time, the distance between the main guide plate 4 and the secondary guide plate 22 is adapted to the size of the packaging box 5.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The main guide plate 4 and the secondary guide plate 22 can not only help enhance the stability of the packaging box 5 when it moves on the surface of the workbench 1, and avoid the problem of the packaging box 5 shifting position during the movement, but also help to position the packaging box 5, ensuring that the box cover 3 and the buffer layer 12 can be smoothly set to the corresponding positions of the packaging box 5. The inclined structure at both ends of the secondary guide plate 22 can also help reduce the probability of the secondary guide plate 22 interfering with the movement of the packaging box 5.

[0032] This utility model's packaging machine for producing craft ceramics, through the cooperation of the main partition plate 2, the main push plate 17, the secondary partition plate 14, the secondary push plate 13, the limiting plate 11, and the conveying assembly 8, enables the packaging machine to automatically fill the buffer layer 12 into the packaging box 5, thereby enhancing the safety of the craft ceramics after packaging. At the same time, the side electric rod 6, the conveying assembly 8, the electric rod one 16, the electric rod two 15, the main vertical electric rod 19, and the secondary vertical electric rod 21 can all be electrically connected to an external control center or PLC assembly, thereby helping to improve the production efficiency of the packaging machine. The conveying assembly 8 is a common brand and model on the market.
