Description

Technical Field

[0001] This utility model relates to the field of curing kiln technology, and in particular to a lead-acid battery heating curing kiln. Background Technology

[0002] The heating curing kiln, also known as the curing chamber or maturation chamber, is one of the core pieces of equipment in the production of lead-acid battery plates. Its main task is to heat-treat the coated green plates under specific temperature, humidity and time conditions.

[0003] Patent publication number CN222951521U discloses a curing kiln that reduces heat loss. This curing kiln, by setting the curing kiln body and top plate to a double-layer vacuum, can prevent heat loss and save the energy required to heat the inside of the curing kiln body. After the object is cured, the limiting plate is pulled out of the limiting groove, releasing the limiting of the top plate, allowing the top plate to move upward and dissipate the heat inside the curing kiln body. This prevents the components inside the curing kiln body from being damaged by prolonged high temperatures, thus reducing its service life.

[0004] However, temperature differences exist between the electrode plates in different areas and locations within the kiln, resulting in inconsistent curing degrees for the same batch of electrode plates, which affects the consistency of battery capacity and lifespan. Summary of the Invention

[0005] The purpose of this invention is to provide a lead-acid battery heating and curing kiln, which solves the problem of uneven heating of existing battery plates during the heating process by using a rotating device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a lead-acid battery heating and curing kiln, comprising a curing kiln body, a support fixedly connected to the back of the curing kiln body, a rotating device, and a fixing assembly. The rotating device includes a gear, a rotating sleeve, a gear ring, and a rotating rod. The gear and the rotating sleeve are rotatably connected to the curing kiln body. The gear ring is fixedly sleeved on the outer wall of the rotating sleeve, and the rotating rod is slidably connected inside the rotating sleeve. The gear meshes with the gear ring. The fixing assembly is fixedly connected to the rotating rod and is used to fix the battery plates.

[0008] As a preferred technical solution of this utility model, the fixing component includes a U-shaped frame, which is fixedly connected to the rotating rod. Limiting grooves are formed on both sides of the inner wall of the U-shaped frame. The two limiting grooves are used to limit the two ends of the battery plates to form a fixation.

[0009] As a preferred technical solution of this utility model, the fixing component further includes a baffle, two elastic telescopic rods and two limiting blocks. The baffle is slidably connected to the U-shaped frame, and the elastic telescopic rods and limiting blocks are fixedly connected to the U-shaped frame. The output end of the elastic telescopic rod is fixedly connected to the baffle, and the limiting block is located on the side of the baffle away from the elastic telescopic rod. The baffle is used to block the entrance of the limiting groove.

[0010] As a preferred embodiment of this utility model, the bracket is equipped with a conveying assembly, which includes an electric push rod and a disc. The electric push rod is fixedly connected to the bracket, the disc is rotatably connected to a rotating rod, and the output end of the electric push rod is fixedly connected to the disc.

[0011] In a preferred embodiment of this utility model, the bracket is fixedly connected to a motor, and the output end of the motor is fixedly connected to a gear.

[0012] As a preferred embodiment of this utility model, the outer wall of the rotating rod is fixedly connected with several limiting strips, and the recessed part of the inner wall of the rotating sleeve is slidably connected with the limiting strips.

[0013] As a preferred technical solution of this utility model, a plurality of the limiting strips are distributed in a ring array on the outer wall of the rotating rod.

[0014] This utility model has the following beneficial effects:

[0015] (I) This utility model uses a rotating device to drive the electrode plate to rotate continuously inside the kiln. The open structure of the U-shaped frame reduces the obstruction of the electrode plate surface. At the same time, the sealing design of the baffle at the entrance of the limiting groove reduces the impact of local airflow disturbance. Combined with the limiting strip to ensure stable transmission of the rotating rod, it enables all parts of the electrode plate to fully contact the heat, thus solving the problem of uneven heating of the battery electrode plate in the traditional heating process.

[0016] (II) This utility model achieves initial positioning by fitting the limiting groove with both ends of the electrode plate, and then uses the elastic telescopic rod to drive the baffle to form a two-way protective structure. During the rotation and axial movement of the electrode plate, it is difficult for it to loosen, fall off or deform due to vibration or centrifugal force. It is easy to operate and has high fixation reliability.

[0017] (III) This utility model realizes automated material discharge after the plate is cured by conveying components, eliminating the need for manual entry into the high-temperature kiln for material handling. This not only improves the efficiency of the production process connection, but also avoids the high-temperature risks that may be faced by manual operation, thus optimizing the safety and efficiency of the overall production process.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a lead-acid battery heating and curing kiln, including a curing kiln body 1, a support fixedly connected to the back of the curing kiln body 1, a rotating device 2, and a fixing assembly 3. The rotating device 2 includes a gear 21, a rotating sleeve 22, a gear ring 23, and a rotating rod 24. The gear 21 and the rotating sleeve 22 are rotatably connected to the curing kiln body 1. The gear ring 23 is fixedly sleeved on the outer wall of the rotating sleeve 22. The rotating rod 24 is slidably connected inside the rotating sleeve 22. The gear 21 meshes with the gear ring 23. A motor 25 is fixedly connected to the support, and the output end of the motor 25 is fixedly connected to the gear 21. The fixing assembly 3 is fixedly connected to the rotating rod 24 and is used to fix the battery. In operation, the battery electrode to be cured is first fixed by the fixing component 3. Then, the motor 25 is started to drive the gear 21 that meshes with the gear ring 23 to rotate. The gear 21 drives the rotating sleeve 22, which is fixedly fitted with the gear ring 23, to rotate synchronously. Then, the rotating rod 24, which is slidably engaged with the rotating sleeve 22, drives the fixing component 3, which is fixed with the electrode, to rotate together. This structure drives the electrode to rotate continuously in the curing kiln body 1 through the rotating device 2. With the heating function of the curing kiln body 1, all parts of the electrode can be evenly contacted with heat, which solves the problem of uneven heating of existing battery electrode during the heating process and ensures the consistency of the electrode curing quality.

[0031] Please see Figures 1-4 As shown, a number of limiting strips 26 are fixedly connected to the outer wall of the rotating rod 24, and the inner wall recess of the rotating sleeve 22 is slidably connected to the limiting strips 26; the limiting strips 26 are arranged in a ring array on the outer wall of the rotating rod 24; during operation, the rotating rod 24 forms a sliding fit with the inner wall recess of the rotating sleeve 22 through the ring array of limiting strips 26 on the outer wall. When the gear 21 drives the rotating sleeve 22 to rotate, the limiting strips 26 will synchronously drive the rotating rod 24 to rotate with the rotation of the rotating sleeve 22. At the same time, the rotating rod 24 can slide freely along the axial direction of the rotating sleeve 22 to cooperate with the conveying assembly. 4. Displacement adjustment: This structure, through the fitting design of the limiting strip 26 and the recess of the rotating sleeve 22, realizes the torque transmission between the rotating sleeve 22 and the rotating rod 24, ensuring that the rotating rod 24 can stably follow the rotating sleeve 22 to drive the electrode plate to rotate, ensuring uniform heating of the electrode plate, while retaining the axial movement freedom of the rotating rod 24, so that the electrode plate can flexibly adjust its axial position during the curing process. At the same time, the distribution of the ring array can make the rotating rod 24 more evenly stressed, avoiding jamming or deviation during rotation, improving the stability of equipment operation and the consistency of electrode plate curing quality.

[0032] Please see Figures 2-5 As shown, the fixing component 3 includes a U-shaped frame 31, which is fixedly connected to the rotating rod 24. Limiting grooves 311 are opened on both sides of the inner wall of the U-shaped frame 31. The two limiting grooves 311 are used to limit the two ends of the battery plate to form a fixation. During operation, the two ends of the battery plate to be cured are first inserted into the limiting grooves 311 on both sides of the inner wall of the U-shaped frame. The plate is quickly positioned and fixed by the fit between the limiting grooves 311 and the two ends of the plate. Then, the plate enters the curing kiln body 1 together with the rotating rod 24 for heating and curing. This fixing method has a simple structure and is easy to operate. It can stably limit the displacement and shaking of the plate during heating and rotation, ensuring the consistency of the plate posture. The open structure of the U-shaped frame reduces the obstruction of the plate surface. Combined with the rotating device 2, it improves the uniformity of the plate heating.

[0033] Please see Figures 2-5 As shown, the fixing component 3 also includes a baffle 32, two elastic telescopic rods 33, and two limiting blocks 34. The baffle 32 is slidably connected to the U-shaped frame 31, and the elastic telescopic rods 33 and the limiting blocks 34 are both fixedly connected to the U-shaped frame 31. The output end of the elastic telescopic rod 33 is fixedly connected to the baffle 32, and the limiting block 34 is located on the side of the baffle 32 away from the elastic telescopic rod 33. The baffle 32 is used to block the entrance of the limiting groove 311. During operation, the baffle 32 is first pulled away from the limiting block 34, causing the elastic telescopic rod 33 to contract under force and store elastic potential energy. Then, the two ends of the battery electrode to be cured are precisely embedded into the U-shaped frame 31. Within the limiting groove 311 of the mold frame, after the baffle 32 is released, the elastic telescopic rod 33 pushes the baffle 32 back to its original position under the action of the reset elastic force, tightly sealing the entrance of the limiting groove 311. At this time, the baffle 32 and the limiting block 34 form a two-way protective structure. The baffle 32 prevents the electrode plate from accidentally falling out from the entrance side, while the limiting block 34 restricts the excessive displacement of the baffle 32 from the inside, preventing the baffle 32 from falling out of the entrance of the limiting groove 311 during use. This makes it difficult for the electrode plate to loosen or deform due to vibration and centrifugal force during curing rotation and axial movement. At the same time, the sealing of the entrance of the limiting groove 311 by the baffle 32 can reduce the impact of local airflow disturbance in the kiln on the electrode plate, ensuring uniform heating of all parts of the electrode plate.

[0034] Please see Figures 1-3 and Figure 6As shown, the support frame is equipped with a conveying assembly 4, which includes an electric push rod 41 and a disc 42. The electric push rod 41 is fixedly connected to the support frame, and the disc 42 is rotatably connected inside the rotating rod 24. The output end of the electric push rod 41 is fixedly connected to the disc 42. During operation, after the electrode plate has been heated and cured in the curing kiln, the electric push rod 41 fixed on the support frame is activated. Its output end will drive the disc 42 fixed to it to move axially. Since the disc 42 is rotatably connected inside the rotating rod 24, it can push the rotating rod 24 without affecting the rotation state of the rotating rod 24. Then, the rotating rod 24 drives the fixed assembly 3 with the electrode plate fixed at the front end to move synchronously towards the outlet of the curing kiln. After the electrode plate is conveyed to the outlet position, the electric push rod 41 is turned off to complete the electrode plate discharge operation. This conveying assembly 4 realizes the automated conveying of the electrode plate after curing, eliminating the need for manual entry into the kiln to pick up and put in the electrode plate, thus improving production efficiency and reducing operational risks.
