Description

Technical Field

[0001] This invention belongs to the technical field of kiln auxiliary facilities, specifically relating to a device for opening and closing the sagger travel channel and lifting the sagger. Background Technology

[0002] The aforementioned sagger travel channel opening and closing and sagger lifting device is installed on the sagger conveying device, which is part of the sagger conveying production line, in use. The sagger conveying device is located between the furnace inlet and furnace outlet of the tunnel kiln in use. On the path of the sagger conveying device frame, i.e. the channel, there are, according to process requirements, not limited to, the following examples such as sagger calcining material crushing mechanism, sagger unloading mechanism, sagger cleaning mechanism, and sagger loading mechanism. The saggers containing calcined materials are transported from the furnace to the sagger calcination material crushing mechanism by the sagger conveyor to crush the calcined material (because many materials will produce stubborn lumps after calcination). After crushing at the sagger calcination material crushing station, the sagger conveyor sends it to the sagger unloading mechanism to unload the material from the sagger (or the material can be sucked out directly by the suction pipe at the crushing station). Then, the sagger conveyor transports the unloaded saggers to the sagger cleaning station, where the aforementioned sagger cleaning mechanism cleans them. Next, the sagger conveyor transports the saggers to the loading station, where the sagger loading device loads them. Finally, the sagger conveyor sends the material into the furnace from the furnace inlet, thus forming a cyclical, highly efficient production line process. Of course, if a non-damaged sagger inspection mechanism is added between the sagger cleaning mechanism and the sagger loading mechanism, then the saggers will enter the loading mechanism after passing through the damaged sagger inspection mechanism.

[0003] When the aforementioned crucibles are conveyed to the feeding station by the crucible conveyor of the crucible conveying production line, a crucible positioning signal collector, such as a photoelectric switch, installed on the frame of the crucible conveyor collects the signal and feeds it back to the electrical controller. The electrical controller then sends a signal to the crucible travel channel opening and closing mechanism, causing it to rise and block the crucible's travel channel, thus temporarily stopping the crucible at the loading station. Immediately afterwards, a pair of crucible clamping mechanisms clamp (and immediately release) the crucible to ensure that its position is in the center required by the process. Under the command of the electrical controller, the crucible lifting device (also called the "crucible hoisting device") corresponding to the area below the loading station lifts the crucible upwards, so that the bottom of the crucible is away from the crucible conveying roller on the frame of the crucible conveyor, allowing the crucible to receive the filling. After the saggers are loaded, the sagger travel channel opening and closing device is lowered to open the sagger travel channel, and the sagger lifting device is lowered to place the saggers loaded with material onto the sagger conveying rollers. Then, the sagger conveying roller drive mechanism on the sagger conveying device frame drives the sagger conveying rollers to move, and the saggers loaded with material are introduced into the furnace from the furnace inlet for calcination.

[0004] As can be seen from the above description, the aforementioned crucible travel channel opening and closing device and crucible lifting device are for the loading station set on the path of the crucible conveyor frame of the production line. The crucible travel channel opening and closing device and the crucible lifting device are indispensable devices in the structural system of the production line crucible conveyor. Based on the principle of applying one example to others, the aforementioned two devices are also set up as needed in other stations.

[0005] Technical information related to the opening and closing device of the sagger travel channel and the sagger lifting device can be found in publicly available Chinese patent documents. A typical example of the former is the "Automatic Weighing and Shaking Device for Saggers with Sagger Channel Opening and Closing Function" recommended by CN104896943B. The specific structure and function of the sagger channel opening and closing mechanism in this patent can be found in paragraphs 0037 and 0040 to 0041 of its specification. This patent not only has the problem of weak resistance to sagger impact, but also is prone to deformation of the cylinder column of the stop lever lifting cylinder due to prolonged use, which may damage the stop lever lifting cylinder. This is because the stop lever lifting cylinder is set with its cylinder column facing upwards, and because the middle part of the stop lever is connected to the end (upper end) of the cylinder column along its length, the stop lever will vibrate along with the cylinder column when the sagger hits the stop lever during travel. Although the sagger first contacts the left and right guide rod rollers on the left and right guide rods, the impact is ultimately borne by the stop lever. Typical examples of the latter include the "sagger lifting device" provided by CN214132068U and the "a sagger lifting device" described in CN215516491U. However, these two patents are not limited to those with relatively weak sagger lifting capabilities, and their structures also have limitations. Specifically, they struggle to handle relatively heavy and large saggers. This is because, in order to increase production capacity per unit time and correspondingly save energy, the industry has reasonably increased the specifications of saggers, especially graphite saggers used for calcining new energy battery materials (this is just one example), to lengths of 70cm, widths of 70cm, and heights of 29cm, 32cm, or 35cm, etc. Therefore, if the existing sagger channel opening and closing mechanism, such as that in the patent recommended by CN104896943B, is adopted, the large inertia of the sagger makes it easier to damage the aforementioned baffle and cylinder configuration in the structure of the sagger channel opening and closing mechanism. Furthermore, if the sagger lifting device structure provided by the two aforementioned patents is adopted, it is insufficient to meet the industry's expectation of smooth lifting of the heavy and relatively large sagger. Summary of the Invention

A crucible movement guide guard is fixed on the upper part of the opposite side of the front and rear support beams of the crucible conveyor roller at the loading station and along the length direction of the front and rear support beams of the crucible conveyor roller at the loading station.

[0016] In yet another specific embodiment of the present invention, the loading station crucible conveyor roller drive mechanism includes a crucible conveyor roller drive motor, a crucible conveyor roller drive reduction gearbox, a crucible conveyor roller drive reduction gearbox sprocket, a right transition sprocket, a left transition sprocket, a right redirecting sprocket, a loading station crucible conveyor roller drive chain, and a pair of crucible conveyor roller drive chain guide bars.

[0017] The technical advantages of the present invention are as follows: Because the front and rear ends of the stop frame of the loading station's crucible travel channel opening and closing mechanism are fixed to the front and rear sides of the upper left side of the loading station frame, respectively, and because the stop plate actuation cylinder, which uses the stop frame as a carrier, is set in a horizontal position, the center of gravity of the entire loading station's crucible travel channel opening and closing mechanism is significantly lowered. This helps to effectively resist the impact of crucibles with high inertia, avoid deformation, and reliably and persistently perform the function of opening and closing the crucible travel channel at the loading station as needed. Furthermore, because the loading station's crucible lifting mechanism uses front and rear worm gear boxes driven by a crucible lifting drive motor, and the front and rear worm gear shafts of the front and rear worm gear boxes respectively drive the lifting of the crucible lifting frame fixing plate along with a set of crucible lifting frames fixed to its upper part, this significantly increases the lifting capacity of heavy crucibles and ensures stability during the lifting process, preventing fluttering and swaying.

[0027] Preferably, a buffer damping plate 251 is fixed on the upper right side of the aforementioned stop plate 25.

[0028] In this embodiment, the aforementioned damping plate 251 is a rubber plate, but it can also be a nylon plate or a resin plate. When the crucible impacts the stop plate 25, the damping plate 251 first acts as a damping buffer.

[0029] In this embodiment, the aforementioned sagger lifting drive motor 32 is a servo motor with forward and reverse rotation functions.

[0030] See Figure 2 And combined Figure 1The applicant describes the working principle of the aforementioned crucible lifting mechanism 3 at the loading station. When the crucible position signal acquisition device, such as a photoelectric switch, installed on the loading station frame 11 at loading station 1 detects the position of the crucible moving from right to left, it indicates that the crucible has reached the position required by the process between the aforementioned pair of loading station crucible clamping mechanisms 4, that is, the crucible has reached the position corresponding to the aforementioned loading station crucible lifting mechanism 3 and between the pair of loading station crucible clamping mechanisms 4. As the aforementioned crucible position signal acquisition device feeds back the signal to the electrical controller, the electrical controller issues a working command to the loading station crucible travel channel opening and closing mechanism 2, causing the stop plate 25 to rise and stop the crucible from continuing to move. Specifically: the stop plate actuating cylinder 23 operates, causing the stop plate actuating cylinder pin 232 to shift. The stop plate actuating cylinder pin 232, through the cylinder pin hinge seat 245, drives the lower hinge shaft 243 of the connecting rod. The lower hinge shaft rollers 2431 at the front and rear ends of the lower hinge shaft 243, along with the lower ends of the left and right connecting rods 241 and 242, shift. Simultaneously, the upper ends of the left and right connecting rods 241 and 242 drive the upper hinge shaft 244 of the connecting rod. The upper hinge shaft 244 then drives the lower part of the stop plate 25. Stop plate 25 rotates counterclockwise by an angle at the front and rear ends of its stop plate hinge shaft 253 at positions corresponding to the stop plate hinge shaft hole 223, causing the upper end of stop plate 25 to rise upwards corresponding to the position of the conveyor roller space 51 (to be mentioned below). This acts like a lifting gate, closing the leftward passage of the crucible. When the crucible is stopped by stop plate 25, a pair of loading station crucible clamping mechanisms 4 clamp the crucible briefly and then immediately release it, ensuring that the crucible is positioned precisely in the receiving position required by the process. The reverse is also true, and will not be elaborated further. As can be seen from the foregoing description, the pair of loading station crucible clamping mechanisms 4 can essentially be called crucible alignment mechanisms or crucible centering mechanisms.

[0031] Please see Figure 3The applicant describes the working principle of the aforementioned crucible lifting mechanism 3 at the loading station. After the pair of crucible clamping mechanisms 4 at the loading station complete the centering of the crucible (the pair of crucible clamping mechanisms 4 leave the crucible, that is, release the contact with both sides of the crucible), when the crucible lifting drive motor 32 receives the working command from the electrical controller, it enters the working state. The crucible lifting drive motor shaft 322 drives the active synchronous pulley 34a, which in turn drives the driven synchronous pulley 34b via the synchronous belt 35. The driven synchronous pulley 34b drives the linkage worm gear 33, which in turn drives the front worm gear box 36a and the rear worm gear box 36b. The worm wheels in the front and rear worm gear boxes 36a and 36b respectively drive the front and rear worm gear shafts 36e and 36f, which serve as worm gear shafts, to move upward. The upward displacement of the front and rear worm gear shafts 36e and 36f causes the crucible lifting bracket fixing plate 36c, along with the crucible lifting bracket 36d fixed on its upward-facing side, to move upward at the position corresponding to the conveying roller space 51 (to be mentioned later). The three crucible lifting brackets 36d lift the crucible upward, that is, push the empty crucible waiting to be filled upward, so that the bottom surface of the crucible is away from the crucible conveying roller 5 of the filling station (to be mentioned later), and it is in the receiving (filling) state. When the amount of material in the crucible reaches the weight set value of each pair of crucible material front and rear weighing sensors 38a and 38b mentioned above, the respective pair of crucible material front and rear weighing sensors 38a and 38b feeds a signal back to the electrical controller, causing the feeding mechanism corresponding to the upper part of the crucible to stop filling the crucible. Then, the aforementioned loading station sagger travel channel opening and closing mechanism 2 reverses its operation, causing the stop plate 25 to move downwards and return to the bottom of the conveyor roller space 51. At the same time, the loading station sagger lifting mechanism 3 reverses its operation, causing a set of sagger lifting frames 36d to move downwards to the bottom of the conveyor roller space 51, thereby placing the sagger filled with material (i.e., the sagger that has reached the filling amount) on the loading station sagger conveyor roller 5. Under the movement of the loading station sagger conveyor roller 5 caused by the aforementioned loading station sagger conveyor roller drive mechanism 6, the sagger is sent into the furnace.

[0032] See you later Figure 1The aforementioned loading station frame 11 is supported on the ground in use. A front support beam 111 for the loading station crucible conveyor roller is fixed to the upper front side of the loading station frame 11 along its length, and a rear support beam 112 for the loading station crucible conveyor roller is fixed to the upper rear side of the loading station frame 11 along its length. The front and rear support beams 111 and 112 of the loading station crucible conveyor roller are parallel to each other in the length direction, and the loading station crucible conveyor roller is rotatably arranged from left to right at intervals between the opposing sides of the front and rear support beams 111 and 112. The front end of the loading station sagger conveyor roller 5 extends to the front side of the aforementioned loading station sagger conveyor roller front support beam 111 and is fixed with the loading station sagger conveyor roller sprocket 52. The distance between two adjacent loading station sagger conveyor rollers 5 constitutes the conveyor roller space 51 mentioned above. The aforementioned stop plate 25 and the aforementioned sagger lifting frame 36d correspond to the aforementioned conveyor roller space 51. A loading station sagger conveyor roller drive mechanism 6 is provided on the upper front side of the aforementioned loading station frame 11. The loading station sagger conveyor roller drive mechanism 6 is connected to the aforementioned loading station sagger conveyor roller sprocket 52 for transmission.

[0033] The cross-sectional shapes of the front and rear support beams 111 and 112 of the aforementioned loading station crucible conveyor roller are respectively ]-shaped and [-shaped. A crucible movement guide guard strip 113 is fixed on the upper part of the opposite side of the front and rear support beams 111 and 112 of the loading station crucible conveyor roller and along the length direction of the front and rear support beams 111 and 112 of the loading station crucible conveyor roller.

[0034] The preferred, but not absolutely limited, structure of the aforementioned crucible conveyor roller drive mechanism 6 at the loading station is as follows: It includes a crucible conveyor roller drive motor 61, a crucible conveyor roller drive reduction gearbox 62, a crucible conveyor roller drive reduction gearbox sprocket 63, a right transition sprocket 64, a left transition sprocket 65, a right redirecting sprocket 66, a loading station crucible conveyor roller drive chain 67, and a pair of crucible conveyor roller drive chain guide bars 68. The crucible conveyor roller drive motor 61 is in transmission cooperation with the crucible conveyor roller drive reduction gearbox 62 and is connected by the crucible conveyor roller drive reduction gearbox 62. The sagger conveyor roller drive motor 61 is fixed on the sagger conveyor roller drive reduction gearbox base 622, which is fixed to the right end of the aforementioned loading station frame 11. The sagger conveyor roller drive reduction gearbox shaft 621 of the sagger conveyor roller drive reduction gearbox 62 faces forward, and the sprocket 63 of the sagger conveyor roller drive reduction gearbox is fixed on the sprocket 621. The right transition sprocket 64 is located slightly to the left of the sprocket 63 of the sagger conveyor roller drive reduction gearbox and rotates via the right transition sprocket shaft 641. The left transition sprocket 65 is rotatably mounted on the front support beam 111 of the crucible conveyor roller at the loading station via the left transition sprocket shaft 651 at the left end of the front support beam 111 and corresponds to the left ends of a pair of crucible conveyor roller drive chain guides 68. The right redirecting sprocket 66 is rotatably mounted on the front right end of the front support beam 111 of the crucible conveyor roller at the loading station via the right redirecting sprocket shaft 611 and corresponds to the right ends of a pair of crucible conveyor roller drive chain guides 68. The crucible conveyor roller drive chain at the loading station... The chain 67 is sequentially fitted onto the sprocket 63, right transition sprocket 64, left transition sprocket 65 and right redirecting sprocket 66 of the crucible conveyor roller drive gearbox. The crucible conveyor roller drive chain 67 of the loading station also passes through the guide bar space formed between a pair of crucible conveyor roller drive chain guide bars 68 and is connected to the aforementioned crucible conveyor roller sprocket 52 of the loading station. The pair of crucible conveyor roller drive chain guide bars 68 are fixed vertically and horizontally in a parallel state to the front side of the front support beam 111 of the crucible conveyor roller of the loading station in the length direction.

[0035] Under the control of the loading station crucible conveyor roller drive mechanism 6, which is controlled by the electrical controller, the crucible conveyor roller drive motor 61 drives the crucible conveyor roller drive reduction gearbox 62, the crucible conveyor roller drive reduction gearbox shaft 621 drives the crucible conveyor roller drive reduction gearbox sprocket 63, the crucible conveyor roller drive reduction gearbox sprocket 63 drives the loading station crucible conveyor roller drive chain 67, and the loading station crucible conveyor roller drive chain 67 drives the loading station crucible conveyor roller sprocket 52. This causes the loading station crucible conveyor roller 52 to move, moving the crucibles on it from right to left under the guidance of a pair of crucible movement guide guards 113. When the crucibles move to a level where a signal can be collected by a crucible position signal acquisition device, such as a photoelectric switch, installed on the loading station frame 11, the crucible position signal acquisition device feeds back the signal to the electrical controller, causing the aforementioned loading station crucible travel channel opening and closing mechanism 2 to rise, preventing the crucibles from continuing to move to the left. Simultaneously, as described above, a pair of loading station crucible clamping mechanisms 4 straighten the crucible's clamping position. That is, the crucible is first clamped by the pair of loading station crucible clamping mechanisms 4, and then immediately released, thus aligning the crucible to a perfectly centered position. Next, the electrical controller sends a working command to the loading station crucible lifting mechanism 3, causing it to operate and position the crucible to receive feeding from the feeding mechanism. As mentioned above, when each pair of front and rear weighing sensors 38a and 38b detects that the amount of material in the crucible has reached the weight set by the process, the sensors 38a and 38b send a signal back to the feeding mechanism, causing the feeding mechanism to stop feeding. At the same time, the crucible travel channel opening and closing mechanism 2 at the loading station receives a command from the electrical controller and causes the stop plate actuation cylinder 23 to work in the opposite direction, causing the stop plate 25 to descend to the point of releasing the obstruction to the crucible travel channel. Simultaneously, the crucible lifting mechanism 3 at the loading station also receives a command from the electrical controller and causes the crucible lifting drive motor 32 to perform the opposite action, until a set of crucible lifting frames 36d descends to the point of placing the crucibles containing material onto the crucible conveying rollers 5 at the loading station. Since the sagger conveyor roller drive mechanism 6 at the loading station is in operation, the sagger conveyor roller 5 at the loading station is also in motion (rotation), thus moving the loaded sagger to the left and into the kiln chamber. The next empty sagger awaiting loading then moves from right to left to the position between the aforementioned pair of loading station sagger clamping mechanisms 4. This process is repeated to achieve a relay-style continuous production effect. Since the structure of the aforementioned pair of loading station sagger clamping mechanisms 4 is known technology, see, for example, Chinese patent document authorization announcements CN104180664B, CN103521314B and CN104165523B, etc., the applicant will not elaborate further.

[0036] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
