Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller kiln conveying structures, in particular to a sagger differential speed arranging conveying device suitable for the tail end of a roller kiln. Background Art
[0002] Currently, most lithium battery sintering kilns are fully automated roller hearth kilns, sintering lithium battery raw materials 24 / 7. Current roller hearth kilns typically operate at sintering temperatures as high as 1300°C. SiSiC rollers are commonly used as conveyor shafts for transporting the sintered material. These rollers must cross the kiln to transmit power to the saggers. However, due to limitations in the SiSiC roller production process, the rollers are not perfectly straight, with deviations in straightness as high as 4mm. Furthermore, the roller kiln utilizes a spring-clutch transmission to power the SiSiC rollers, limiting their adjustment range. As the temperature rises, the SiSiC rollers deform more, with the center section deforming more than the ends. Consequently, the linear velocity of the saggers transported in the center of the rollers, after each rotation, is slightly greater than that at the ends. This results in uneven saggers after long-distance transport. In addition, when conveying saggers in a roller hearth kiln, the linear speed of the roller surface will have slight deviations due to the deviation in the straightness of the rollers. In order to meet the needs of actual production, the production capacity of current roller hearth kilns has been continuously improved, and the length of roller hearths has been continuously increased. The slight deviation in linear speed caused by a single roller is accumulated over a long period of conveying in the roller hearth kiln, resulting in the situation where the saggers conveyed in the middle are faster than those conveyed on the sides. In serious cases, the deviation between the front and rear saggers is as much as one sagger position, which makes it extremely difficult to arrange the entire kiln in an atmosphere roller hearth kiln. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a sagger differential speed arranging conveying device suitable for the tail end of a roller kiln.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a differential speed aligning and conveying device for saggers suitable for the tail end of a roller kiln, comprising at least one group of differential speed aligning components arranged at the tail end of the roller kiln and used to carry and convey a sagger group, wherein each group of the differential speed aligning components comprises an acceleration section and a deceleration section arranged in sequence, and the conveying speed of the acceleration section is faster than the conveying speed of the deceleration section; the acceleration section is used to accelerate any group of saggers carried to increase the front-to-rear distance between the sagger group and the next group of saggers; the deceleration section is used to decelerate any group of saggers carried so that the saggers of the same sagger group are aligned at the intersection of the acceleration section and the deceleration section.
[0005] Furthermore, the invention comprises at least two groups of differential speed aligning components sequentially arranged at the rear end of the roller kiln, and each group of the differential speed aligning components sequentially accelerates and aligns any group of saggers.
[0006] Furthermore, the acceleration section includes a plurality of acceleration rollers that are horizontally arranged along the conveying direction and are synchronously powered.
[0007] Furthermore, the deceleration section includes a plurality of deceleration rollers that are horizontally arranged along the conveying direction and are synchronously powered.
[0008] Furthermore, the deceleration section includes a plurality of unpowered deceleration rollers arranged horizontally along the conveying direction.
[0009] Furthermore, the conveying distance of the deceleration section is shorter than the length of the sagger.
[0010] Furthermore, the roller kiln is provided with a constant speed section for conveying the sagger group at an upstream position and / or downstream position in the conveying direction of the differential speed aligning assembly.
[0011] The present invention adopts the above-mentioned scheme, and its beneficial effect is that the present invention adopts the design of a differential aligning component, and the acceleration section and deceleration section of the component are used to control and operate the sagger group in an orderly manner. Specifically, during the sagger conveying process, the acceleration section of the differential aligning component plays a vital role. When the sagger group enters the acceleration section, the movement speed of the sagger group is gradually increased. After the speed of the sagger group is increased, the deceleration section of the differential aligning component begins to play a role. Through the deceleration operation, the component gradually reduces the movement speed of the sagger group, thereby achieving the purpose of shortening the distance deviation between saggers in the same group. This deceleration aligning method not only ensures the relative position relationship between the saggers, but also avoids the saggers from being scattered or misplaced due to excessive speed.
[0012] The differential speed alignment assembly of this utility model fully considers the characteristics and conveying requirements of saggers. During acceleration and deceleration, the assembly precisely controls the speed differential, allowing the saggers in a group to first accelerate and separate by a certain distance, then decelerate to reduce this distance difference, thus completing the alignment operation. This design not only ensures sagger conveying efficiency but also improves alignment accuracy, ensuring that the saggers remain neatly organized during conveyance.
[0013] In summary, this utility model, through its differential alignment assembly design, achieves efficient and precise conveying and alignment of saggers. Its beneficial effects are not only reflected in improved conveying efficiency and alignment accuracy, but also in enhanced versatility and adaptability. This innovative design is of great significance for advancing the overall level of sagger conveying technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.
[0018] See attached Figure 1-2 As shown, in this embodiment, a sagger differential alignment conveying device suitable for the tail end of a roller hearth kiln is suitable for the tail end position of an existing roller hearth kiln to facilitate the alignment of the groups of saggers A about to be sent out of the roller hearth kiln. Each group of saggers A is composed of a plurality of saggers arranged in a row. Specifically, it includes at least one group of differential alignment assemblies 1 arranged at the tail end of the roller hearth kiln and used to carry and convey the saggers A. Each group of differential alignment assemblies 1 includes an acceleration section 100 and a deceleration section 200 arranged in sequence. The conveying speed of the acceleration section 100 located at the rear end of the roller hearth kiln in the forward direction is faster than the conveying speed of the deceleration section 200, resulting in a speed difference between the acceleration section 100 and the deceleration section 200.
[0019] In this embodiment, after each group of saggers A is fired in the roller kiln, it will be gradually sent out in the conveying direction of the transfer roller kiln, and the differential array assembly will be used to align each group of saggers A at the rear end of the roller kiln. Figure 2 Define the state of each sagger group A before and after adjustment by the differential aligning assembly 1, define A1 as the state of the sagger group when it is sent from the initial state to the acceleration section 100 of the first differential aligning assembly 1 for adjustment, A2 is the state of the sagger group when it is adjusted in the deceleration section 200 of the first differential aligning assembly 1, A3 is the state of the sagger group when it is adjusted in the acceleration section 100 of the second differential aligning assembly 1, A4 is the state of the sagger group when it is adjusted in the deceleration section 200 of the second differential aligning assembly 1, and A5 is the state of the sagger group after the adjustment is completed.
[0020] Specifically, the acceleration section 100 is used to accelerate any group of sagger groups A carried by it to increase the front-to-rear distance between the sagger group A and the next group of sagger groups A, that is, any group of sagger groups A is transferred from the roller kiln to the acceleration section 100, and because the conveying speed of the acceleration section 100 is faster than the conventional conveying speed of the roller kiln, the acceleration section 100 pulls the saggers of the group of sagger groups A to speed up, so that the front-to-rear distance between the group of sagger groups A and the next group of sagger groups A that have not been transferred to the acceleration section 100 gradually increases, until the group of sagger groups A leaves the acceleration section 100 or the next group of sagger groups A enters the acceleration section 100 (that is, refer to Figure 2 As shown, the sagger group A switches from the initial state to the accelerated state shown in A1), and the final front-to-back distance increases by about 50 mm (this is specifically determined by the speed and conveying distance of the acceleration section 100, which is not specifically limited here, and those skilled in the art can set it according to actual needs).
[0021] Specifically, the deceleration section 200 is used to decelerate any group of saggers A that have been accelerated so that the saggers of the same sagger group A are aligned at the intersection of the acceleration section 100 and the deceleration section 200. That is, when any sagger group A reaches the intersection of the acceleration section 100 and the deceleration section 200, due to the speed difference between the acceleration section 100 and the deceleration section 200 (that is, referring to Figure 2 As shown, the sagger group A switches from the accelerated state shown in A1 to the decelerated state shown in A2, thereby decelerating the individual saggers of the sagger group A. Since the saggers of the same sagger group A are staggered and unevenly arranged, the saggers located in the front are decelerated first, while the saggers located in the rear maintain a relatively high speed before contacting the deceleration section 200. This causes the saggers in the same sagger group A to appear slow in front and slow in the back, shortening the distance deviation between the saggers, and ultimately achieving the alignment operation between the saggers in the same sagger group A. After the saggers in the same sagger group A completely exit the acceleration section 100 and are transferred to the deceleration section 200, the saggers can be kept aligned and moved forward synchronously. During the alignment period, the deceleration effect of the deceleration section 200 on the sagger group A gradually reduces the front-to-back distance between the sagger groups A that are transferred to the acceleration section 100, thereby reducing the front-to-back distance to the rated distance, thereby avoiding interference with subsequent normal production work.
[0022] In this embodiment, at least two groups of differential aligning assemblies 1 are sequentially arranged at the rear end of the roller kiln. Each group of differential aligning assemblies 1 sequentially accelerates and aligns any group of saggers A. For ease of understanding, the following explanation is specifically combined with two groups of differential aligning assemblies 1. Any sagger group A first passes through the acceleration section 100 and deceleration section 200 of the first group of differential aligning assemblies 1 to accelerate and decelerate, and then sequentially completes the first acceleration and aligning action (i.e., refer to Figure 2 As shown, the sagger group A is first switched from the initial state to the acceleration state shown by A1, and then switched from the acceleration state shown by A1 to the deceleration state shown by A2); then, the sagger group A is transferred from the deceleration section 200 of the first differential aligning assembly 1 to the acceleration section 100 of the second differential aligning assembly 1 (at this time, since the sagger group A has been aligned once, the problem of increased distance deviation between the saggers in the same sagger group A will not be caused by the differential speed between the deceleration section 200 and the acceleration section 100), and then the speed increase and deceleration are repeated to complete the second acceleration and alignment action in sequence (i.e., refer to Figure 2 As shown, the sagger group A first switches from the deceleration state shown by A2 to the acceleration state shown by A3, then switches from the acceleration state of A3 to the deceleration state of A4, and finally switches from the deceleration state of A4 to the level arrangement state shown by A5). In this way, through multiple alignment actions, the saggers in the same group can be adjusted to the level arrangement state (i.e., refer to Figure 2 The A5 is shown in the flush arrangement state).
[0023] In this embodiment, the acceleration section 100 includes a plurality of acceleration rollers arranged horizontally along the conveying direction and synchronously powered, that is, the acceleration rollers of the acceleration section 100 can be synchronously linked by relying on the same drive device (such as a transmission motor equipped with a transmission connection, not shown in the figure).
[0024] In this embodiment, the deceleration section 200 can adopt two structural forms as shown below:
[0025] Implementation structure form one: the deceleration section 200 includes a number of deceleration rollers arranged horizontally along the conveying direction and synchronously powered, that is, the various deceleration rollers of the deceleration section 200 can be synchronously linked by relying on the same drive device (such as a transmission motor equipped with a transmission connection, not shown in the figure). The structural form here can be the deceleration section 200 of the first group of differential alignment components 1 in the above embodiment, so that the deceleration section 200 has a certain conveying speed to carry the conveying sagger group A.
[0026] Implementation structure form two: the deceleration section 200 includes a number of unpowered deceleration rollers arranged horizontally along the conveying direction, that is, the deceleration rollers of the deceleration section 200 are not equipped with a driving device and do not have the ability to transport independently, so that the sagger group A mainly relies on the inertia of the sagger to move, and the speed difference between this type of deceleration section 200 is greater than that between the acceleration sections 100. In addition, the conveying distance of this type of deceleration section 200 should not be too long. If it is too long, the inertia of the sagger will not be enough to drive the sagger out of the deceleration section 200, causing the problem of sagger aggregation. Therefore, the conveying distance of the deceleration section 200 here is less than the length of the sagger, so that the front end of the sagger is separated from the deceleration section 200, and its tail end has not yet separated from the acceleration section 100, and can still be pulled by the acceleration of the acceleration section 100, which not only ensures the effect of differential alignment, but also avoids the problem of aggregation.
[0027] In this embodiment, the roller kiln is provided with a constant speed section 300 for conveying sagger groups A at both the upstream and / or downstream positions in the conveying direction of the differential aligning assembly 1. With the aid of the constant speed section 300, several groups of sagger groups A are supported and continuously fed into the differential aligning assembly 1 at a constant speed, or the constant speed section 300 supports several groups of sagger groups A and continuously conveys them from the differential aligning assembly 1 to the rear end of the roller kiln. At the upstream position of the differential aligning assembly 1, the function of the constant speed section 300 is mainly reflected in the continuous constant speed feeding of the sagger groups A. Before entering the differential aligning assembly 1, the sagger groups A need to pass through the support of the constant speed section 300 to ensure that they can enter the differential aligning assembly 1 at a stable speed. In this way, the aligning and positioning process of the sagger groups A in the differential aligning assembly 1 will be smoother, avoiding misalignment or product damage caused by unstable speed.
[0028] Downstream of the differential-speed aligning assembly 1, the constant-speed section 300 is primarily responsible for continuously conveying the sagger group A to the rear end of the roller hearth kiln. After being aligned by the differential-speed aligning assembly 1, the sagger group A must exit the roller hearth kiln at a stable speed, supported by the constant-speed section 300, for subsequent cooling and packaging processes. The constant-speed section 300 ensures the stability and consistency of the sagger group A as it exits the roller hearth kiln, effectively guaranteeing the final quality of the product.
