Description

Technical Field

[0001] The present invention relates to the technical field of ceramic firing, in particular to a ceramic firing device. Background Art

[0002] Ceramics are made of clay with high viscosity and strong plasticity as the main raw material. They have the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. They can be used as structural materials, tool materials and mold materials.

[0003] Chinese patent CN217764423U discloses an electric kiln for firing ceramics, which uses an electric push rod to push the firing plate and ceramics to move. During the movement of the firing plate, the slider will slide on the surface of the slide rail. The slide rail can provide auxiliary protection for the moving ceramics, so that the ceramics maintain stability during the movement and adjustment process. The electric push rod can push the ceramics out of the electric kiln, making it convenient for staff to take the fired ceramics and avoid burns to staff inside the electric kiln.

[0004] The above-mentioned device pushes the firing plate out through an electric push rod, making it easier for workers to take and place ceramics. However, during the entire process, workers still need to operate close to the furnace body, which poses certain safety hazards. This problem is particularly obvious in the process of taking out ceramics. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a ceramic firing device to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a ceramic firing device to solve the problem that the existing device proposed in the above background technology pushes the firing plate out through an electric push rod, making it easier for workers to take and place ceramics, but during the whole process, workers still need to operate close to the furnace body, which poses certain safety hazards.

The clamping unit includes a positioning block elastically connected to the outer peripheral wall of the rotating shaft. The positioning block is located at one end of the outer side of the rotating shaft and has a spherical structure. A plurality of positioning holes that cooperate with the positioning blocks are evenly opened on the inner wall of the ring.

[0015] As a further solution of the present invention: the card block and the card slot are both T-shaped structures.

[0016] As a further solution of the present invention: a T-shaped clamping strip is fixedly provided on the inner side surface of the limit rod, and the clamping strip passes through the hanging plate and is slidably engaged with the hanging plate.

DETAILED DESCRIPTION

[0030] like Figures 1-10 When the trolley 3 is in a vertical position, the trolley 3 is in a vertical position, and ...

[0031] Rotating components that cooperate with the auxiliary rail 2 are provided on both sides of the bottom surface of the trolley 3. When the auxiliary rail 2 cooperates with the trolley 3 through the rotating components, the auxiliary rail 2 can deflect relative to the trolley 3.

[0032] The above-mentioned rotating assembly includes a hanging plate 7 fixed to the bottom of the trolley 3. When the trolley 3 slides on the main rail 4, the bottom surface of the hanging plate 7 can contact the top surface of the main rail 4. The hanging plate 7 is provided with an arc-shaped limiting rod 9. The limiting rod 9 passes through the hanging plate 7 and slides with the hanging plate 7. A clamping block 901 is fixed on the top end surface of the limiting rod 9. Figure 5-Figure 9When the trolley 3 is in a state of being rotated, the upper and lower rails 2 are in a state of being rotated relative to each other, and the upper and lower rails 2 are in a state of being rotated relative to each other, so that the trolley 3 can be rotated relative to the upper and lower rails 2 by rotating the upper and lower rails 2 around the lower and upper rails 2. When the trolley 3 is in a state of being rotated, the upper and lower rails 2 are in a state of being rotated relative to each other, so that the trolley 3 can be rotated relative to the upper and lower rails 2 by rotating the upper and lower rails 2 around the lower and upper rails 2. When the trolley 3 is in a state of being rotated relative to the upper and lower rails 2, the upper and lower rails 2 are in a state of being rotated relative to each other, and the upper and lower rails 2 are in a state of being rotated relative to each other, so that the trolley 3 can be rotated relative to the upper and lower rails 2

[0033] Combine Figure 8 As shown, inclined surfaces 1601 are provided on both sides of the top surface of the block 901. When the auxiliary rail 2 is deflected downward to a horizontal state, as the trolley 3 moves, the block 901 can squeeze the inclined surfaces 1601 on the pressing block 16, thereby squeezing the pressing block 16 into the connecting plate 5, and the block 901 can move out of the slot 501.

[0034] A horizontal shaft 8 is provided at the bottom of the trolley 3 and at the inner side of the connecting plate 5. A sub-gear 12 is fixedly provided near both ends of the horizontal shaft 8, and a transmission tooth meshing with the sub-gear 12 is fixedly provided on the outer peripheral wall of the limit rod 9. Figure 3-Figure 6 In order to install the transverse axis 8, protrusions are fixed on both sides of the bottom surface of the trolley 3, so that the transverse axis 8 passes through the protrusions and rotates with the protrusions through the bearings. Figure 7 As shown, a sleeve 13 is further sleeved at the end position of the transverse shaft 8, the sleeve 13 is fixedly connected to the boss, and a torsion unit is provided in the sleeve 13. The torsion unit can be a torsion spring or a coil spring. Specifically, the torsion unit is sleeved on the outside of the transverse shaft 8 and the two ends of the torsion unit are respectively connected to the outer wall of the transverse shaft 8 and the inner wall of the sleeve 13. The force exerted by the torsion unit on the transverse shaft 8 can drive the transverse shaft 8 to rotate, and then the engagement of the transmission teeth with the pinion 12 drives the limit rod 9 to rotate, so that in the initial state, the clamping block 901 on the limit rod 9 is located at the hanging plate 7;

[0035] A rotating shaft 14 is provided on the side of the horizontal shaft 8 away from the hanging plate 7. A collar 11 is sleeved on the outside of the rotating shaft 14 through a clamping unit, and the collar 11 is connected to the horizontal shaft 8 through a belt or a chain. In addition, a main gear 10 is fixedly sleeved on the rotating shaft 14. Through this structure, when the rotating shaft 14 drives the collar 11 to rotate through the clamping unit, the collar 11 can drive the horizontal shaft 8 to rotate synchronously, thereby adjusting the position of the limit rod 9.

[0036] In actual use, a first rack 6 is installed between the two main rails 4 and near the furnace body 1. The first rack 6 can be fixed to the ground, and a second rack 103 is installed on the bottom surface of the furnace body 1 and near the furnace door 101. The main gear 10 is located above the first rack 6 and the second rack 103, so that the main gear 10 can engage with the first rack 6 or the second rack 103 during horizontal movement. Specifically, the ceramics to be fired are placed on the trolley 3. The trolley 3 in this solution is a single-layer structure. In actual application, the trolley 3 can also be a multi-layer structure.

[0037] In the initial state, the auxiliary rail 2 is located on the side of the trolley 3 close to the furnace body 1, and at this time, the limit rod 9 on the right side of the trolley 3 is in a state of being engaged with the connecting plate 5, so as to maintain the stability of the auxiliary rail 2. In the process of the trolley 3 moving to the end of the main rail 4 close to the furnace body 1, the main gear 10 on the right side of the bottom of the trolley 3 will first mesh with the first rack 6, and then the engagement of the main gear 10 with the first rack 6 drives the rotating shaft 14 and the connecting plate 5 and other structures to rotate counterclockwise. However, since the auxiliary rail 2 on the right side of the trolley 3 is in a vertical state and fits with the trolley 3, the auxiliary rail 2 cannot rotate counterclockwise in this state. In this case, the engaging unit can be separated from the collar 11, so that the rotating shaft 14 is in a state of rotating alone. Similarly, when the main gear 10 on the left side of the trolley 3 passes the first rack 6 (refer to Figure 3-Figure 4 As shown), the limit rod 9 on the left side of the trolley 3 will also rotate counterclockwise, but when the main gear 10 on the left side is offset from the first rack 6, the limit rod 9 on the left side of the trolley 3 can be reset to the initial state;

[0038] Combine Figure 4 As shown, when the trolley 3 moves to the end of the main rail 4 so that the auxiliary rail 2 moves out of the main rail 4, the auxiliary rail 2 is ready for downward deflection. In order for the auxiliary rail 2 to deflect downward stably, the staff can push the auxiliary rail 2 downward through an external tool. When the auxiliary rail 2 is in a horizontal state, it can be located between the main rail 4 and the furnace body 1, which is conducive to the trolley 3 sliding along the main rail 4 and the auxiliary rail 2 into the furnace body 1. Subsequently, when the staff continues to push the trolley 3, the limit rod 9 on the right side of the trolley 3 will push the auxiliary rail 2 and the furnace body 1 into a fit state through the stopper 15. Figure 3-Figure 8 As shown, as the trolley 3 is pushed, the limiting rod 9 on the right side of the trolley 3 will move relative to the connecting plate 5, and the clamping block 901 can squeeze the pressing block 16 into the connecting plate 5, so that the clamping block 901 can pass over the pressing block 16 and eventually move out of the clamping slot 501. After the clamping block 901 moves out of the clamping slot 501, the torsion unit provided can drive the limiting rod 9 on the right side of the trolley 3 to reset;

[0039] Afterwards, in the process of the trolley 3 entering the furnace body 1, the main gear 10 located on the right side of the trolley 3 will first engage with the second rack 103, thereby driving the limit rod 9 on the right side of the trolley 3 to rotate counterclockwise. When the main gear 10 on the right side of the trolley 3 is staggered with the second rack 103, the limit rod 9 on the right side of the trolley 3 will be reset to the initial state. As the trolley 3 gradually enters the furnace body 1, the main gear 10 on the left side of the trolley 3 will engage with the second rack 103 and drive the limit rod 9 on the left side of the trolley 3 to rotate counterclockwise, thereby prompting the block 901 at the end of the limit rod 9 to rotate to a horizontal state and align with the slot 501 on the connecting plate 5. Figure 5 As shown, when the block 901 at the end of the limit rod 9 slides into the slot 501, it can squeeze the pressure block 16 to retract it into the connecting plate 5, and when the block 901 passes over the pressure block 16, it can be located between the pressure block 16 and the stop block 15. At this point, the limit rod 9 on the left side of the trolley 3 is stably engaged with the connecting plate 5. Then, the staff uses a tool to push the auxiliary rail 2 upward to a vertical state. Since the auxiliary rail 2 is stored to one side of the trolley 3, the space between the furnace body 1 and the main rail 4 can be vacated, which does not affect the normal closing of the furnace door 101. The process of the trolley 3 exporting the furnace body 1 is similar to the process of the trolley 3 entering the furnace body 1, and will not be repeated here.

[0040] To sum up, this device is provided with a secondary rail 2 on one side of the trolley 3. When the trolley 3 enters the furnace body 1, the secondary rail 2 can be leveled and positioned between the main rail 4 and the furnace body 1, so that the trolley 3 can be pushed into the furnace body 1 stably. Moreover, after the trolley 3 enters the furnace body 1, the secondary rail 2 can be connected to the other side of the trolley 3, thereby freeing up space between the main rail 4 and the furnace body 1, which will not affect the closing of the furnace door 101. Through this structure, the trolley 3 is relatively smooth and stable during the overall pushing process, thereby maintaining the stability of the ceramic placement. Moreover, during the entire operation, the staff does not need to be close to the furnace body 1, which is safer.

[0041] like Figures 1-10 As shown, guide rails 102 are fixed on both sides of the bottom of the furnace body 1, so that the rollers at the bottom of the trolley 3 can roll to the guide rails 102, thereby facilitating the trolley 3 to stably enter the furnace body 1.

[0042] A notch 301 is provided on the side of the trolley 3 away from the furnace body 1, and the staff can use tools such as a pull rod to pull the trolley 3 out of the furnace body 1 or push the trolley 3 into the furnace body 1. Figure 1-Figure 2 As shown, hooks 201 are fixedly provided on the side and at both ends of the auxiliary rail 2, which is helpful for the staff to lay the auxiliary rail 2 flat or push the auxiliary rail 2 to a vertical state.

[0043] The two ends of the rotating shaft 14 are rotatably mounted with fixed plates, which are fixed to the bottom surface of the trolley 3. Figure 7 As shown, the clamping unit includes a positioning block 1401 arranged on the outer peripheral wall of the rotating shaft 14. Specifically, a blind hole that slides with the positioning block 1401 is opened on the outer peripheral wall of the rotating shaft 14, and a spring is fixedly arranged between the inner end face of the blind hole and the positioning block 1401. The end of the positioning block 1401 located on the outer side of the rotating shaft 14 is a spherical structure, and a plurality of positioning holes 1101 that cooperate with the positioning block 1401 are evenly opened on the inner wall of the collar 11. In the initial state, the rotating shaft 14 and the collar 11 are rotated and one end of the positioning block 1401 is inserted into the positioning hole 1101. When the horizontal shaft 8 overcomes the force of the torsion unit and drives the limit rod 9 to rotate to the extreme position through the cooperation between the positioning block 1401 and the positioning hole 1101, the end of the positioning block 1401 with the spherical structure can move out of the positioning hole 1101.

[0044] Reference Figure 8 As shown, the block 901 and the slot 501 are both T-shaped structures. The bottom surface of the slot 501 is provided with a groove that slides with the pressure block 16. A limiting spring is fixed between the inner end surface of the groove and the pressure block 16. When the auxiliary rail 2 is in a vertical state, the pressure block 16 cooperates with the block 901 to ensure a stable connection between the auxiliary rail 2 and the limiting rod 9.

[0045] The inner side of the limit rod 9 is fixed with a T-shaped structure clip 903, which passes through the hanging plate 7 and slides with the hanging plate 7. The clip 903 is set so that the limit rod 9 and the hanging plate 7 can be stably matched. Figure 10 As shown, a protrusion 902 is fixedly provided on the side of the limit rod 9. When the limit rod 9 is rotated clockwise to the extreme position, the block 901 can fit with the hanging plate 7. When the limit rod 9 is rotated counterclockwise to the extreme position, the protrusion 902 can fit with the hanging plate 7, and at this time the block 901 is in a horizontal state, which is conducive to the docking of the block 901 with the slot 501 on the connecting plate 5.
