Description

Technical Field

[0001] This utility model relates to the field of alumina drying technology, and in particular to an alumina plate and belt drying device that is easy to thread. Background Technology

[0002] Alumina is widely used in electronic devices, aerospace, and semiconductor packaging due to its excellent high-temperature resistance, insulation, mechanical strength, and chemical stability. Drying is one of the key processes in the production of alumina sheets and strips.

[0003] Existing drying ovens typically consist of an oven body with a feed inlet at the top and a discharge outlet at the bottom rear. The oven body has an L-shaped conveyor channel within its interior. Guide rollers are fixedly installed at the corners of the conveyor channel. The strip feeding operation generally involves the strip entering through the feed inlet and falling to the corner of the conveyor channel. Then, the worker's arm reaches into the discharge outlet to grab the strip and pull it out. This method of feeding is extremely inconvenient. Furthermore, to ensure unobstructed access to the discharge outlet for the worker's arm, the outlet is generally quite wide (approximately 100-150mm), causing a large amount of hot gas to escape along with the conveyed strip through the outlet, increasing energy consumption.

[0004] To address this, we designed an alumina sheet and strip drying device that facilitates the threading of the strip. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an alumina plate and strip drying device that is easy to thread.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for easy-to-thread alumina sheet and belt, comprising:

[0008] The box has a long, narrow opening on its top surface;

[0009] A cover plate covers the opening, and a strap gap is formed between the side of the cover plate and the side of the opening;

[0010] The mounting bracket is vertically installed inside the box cavity, with an opening at the top and a fixed connection to the lower surface of the cover plate.

[0011] The inner guide roller is rotatably mounted to the bottom of the mounting frame via a roller frame;

[0012] The drive assembly is located on the outside of the housing and drives the cover to rise and fall;

[0013] The diameter of the inner guide roller is greater than the width of the cover plate but less than the width of the opening.

[0014] Furthermore, the mounting frame is vertically provided with an inner guide post at the bottom. The lower end of the inner guide post passes through the top plate of the roller frame and is provided with a limiting end plate. A spring is sleeved on the body of the inner guide post, and the two ends of the spring abut against the top plate of the roller frame and the limiting end plate, respectively.

[0015] Furthermore, the width of the threading gap is 10-15mm.

[0016] Furthermore, the cover plate extends to the outside of the box at both ends, and each end is connected to at least one vertically downward outer guide post. The top of the end face of the box is provided with a sliding sleeve that slides in cooperation with each outer guide post.

[0017] Furthermore, the driving component includes:

[0018] Drive motor;

[0019] Sprockets are located at the top and bottom of the end face of the housing, with one of the sprockets connected to the output shaft of the drive motor.

[0020] A chain is wound between two sprockets;

[0021] The lower end of the outer guide post is fixedly connected to the vertical section of the chain.

[0022] Furthermore, the drive assembly also includes a drive shaft, which is mounted on the bottom surface of the housing via a bearing seat and is connected to the axle of the bottom sprocket via a gear set.

[0023] Furthermore, heating elements are provided on both inner side walls of the housing and on the inner side of the mounting bracket.

[0024] Furthermore, outer guide rollers are provided on both sides of the opening, and the axis of the outer guide rollers is parallel to the axis of the inner guide rollers.

[0025] Furthermore, the diameter of the inner guide roller is half the sum of the cover plate width and the opening width.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. By controlling the cover plate, mounting frame and inner guide roller to rise and fall synchronously through the drive component, the inner guide roller is located above the box when the belt is threaded. The cover plate, mounting frame and inner guide roller are controlled to fall synchronously through the drive component to complete the belt threading operation. This solves the problem of difficult belt threading in the existing L-shaped channel and greatly reduces the difficulty of operation.

[0028] 2. In the closed state, the gap between the cover plate and the side of the opening is only 10-15mm, which is much smaller than the 100-150mm wide discharge port in the prior art. This effectively suppresses the escape of hot gas and reduces energy consumption.

[0029] 3. The buffer mechanism consisting of the inner guide post and the spring allows the inner guide roller to adapt to the tension of the strip, avoiding strip fluctuation and ensuring a reduction in the width of the belt threading gap;

[0030] 4. The sliding fit between the outer guide post and the sliding sleeve precisely limits the lifting path of the cover plate, preventing sealing failure and uncontrollable gaps caused by swaying. Attached Figure Description

[0035] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0036] Example 1, in conjunction with Appendix Figure 1-3 A drying device for alumina sheet and belt that is easy to thread, comprising:

[0037] The box 1 has a long strip opening 101 at the top, with the width direction consistent with the conveying direction of the strip; heating elements 12 are fixedly installed on the inner walls of both sides and the internal mounting bracket 3; vertical sliding sleeves 11 are provided at the top of both ends.

[0038] Cover plate 2 covers the opening 101, and its width is smaller than the width of the opening 101. Further, the side of cover plate 2 and the side of opening 101 form a 10-15mm wide threading gap (for the thread to enter and exit); both ends extend to the outside of housing 1, and each is connected to at least one external guide post 10 (such as two), and the lower end of the external guide post 10 is connected to the drive assembly 6.

[0039] Mounting bracket 3 is vertically installed inside the box 1, with its upper end passing through opening 101 and fixedly connected to the lower surface of cover plate 2.

[0040] The inner guide roller 4 is rotatably mounted on the bottom of the mounting frame 3 via the roller frame 5; its diameter is greater than the width of the cover plate 2 and less than the width of the opening 101; preferably, it is half the sum of the width of the cover plate 2 and the width of the opening 101.

[0041] The outer guide roller 13 is symmetrically arranged on both sides of the opening 101, and its axis is parallel to the inner guide roller 4.

[0042] As needed, the distance between the vertical plane of the inner side of the outer guide roller 13 and the vertical plane of the corresponding inner guide roller 4 is 0-5mm.

[0043] Drive assembly 6, located on the outside of housing 1, includes:

[0044] The drive motor 601 is installed on the outside of the housing 1.

[0045] Sprockets 602 and chains 603:

[0046] Two sprockets 602 are respectively located at the top and bottom of the end face of the housing 1, and one of the sprockets 602 (such as the bottom sprocket 602) is connected to the output shaft of the drive motor 601.

[0047] The chain 603 is wound between the two sprockets 602, and its vertical section is fixedly connected to the lower end of the outer guide post 10.

[0048] Furthermore, each end of the housing 1 is provided with two sprockets 602 and a chain 603.

[0049] Furthermore, to ensure force balance, the drive assembly 6 also includes a drive shaft 604, which is mounted on the bottom surface of the housing 1 via a bearing seat and is connected to the bottom sprocket 602 via a gear set. At this time, the output shaft of the drive motor 601 is connected to the drive shaft 604, and the drive shaft 604 is connected to the sprocket 602.

[0050] Working principle, combined with appendix Figure 3When threading the alumina strip, the drive motor 601 is started, which drives the two sprockets 602 at the bottom to rotate through the transmission shaft 604, causing the chain 603 to rotate and drive the outer guide post 10 to rise, so that the cover plate 2 and the mounting frame 3 rise synchronously, and the inner guide roller 4 extends out from the opening 101. Then the operator passes the alumina strip through the outer guide roller 13 above and the inner guide roller 4 below. Finally, the drive motor 601 is started again, which drives the two sprockets 602 at the bottom to rotate in the opposite direction through the transmission shaft 604, so that the chain 603 rotates in the opposite direction and drives the outer guide post 10 to fall, so that the cover plate 2, the mounting frame 3 and the inner guide roller 4 are reset. At this time, the alumina strip is pressed into the box 1, and the threading operation is completed.

[0051] Example 2, in conjunction with Appendix Figure 3 A drying device for alumina strip that facilitates threading is described. In Embodiment 1, the roller frame 5 is directly connected to the bottom of the mounting frame 3. When the transmission speed of the alumina strip varies at different positions, the alumina strip may fluctuate, potentially causing scratches when it comes into contact with the side of the threading gap. Therefore, this embodiment differs from Embodiment 1 in that:

[0052] The bottom of the mounting frame 3 is provided with an inner guide post 7. The lower end of the inner guide post 7 passes through the top plate of the roller frame 5 and is fixed to the limiting end plate 8. The spring 9 is sleeved on the body of the inner guide post 7, and its two ends abut against the top plate of the roller frame 5 and the limiting end plate 8 respectively. That is, when the transmission of the alumina strip fluctuates, the roller frame 5 and the inner guide roller 4 will rise or fall accordingly to compensate for the transmission differences of the alumina strip at different positions and ensure that the alumina strip does not fluctuate.

[0053] It should be noted that when transporting alumina strip, a certain tension is required. That is, the supporting force of spring 9 on roller frame 5 is less than the weight of roller frame 5 and inner guide roller 4. In other words, when the tension of alumina strip decreases, roller frame 5 and inner guide roller 4 can compress spring 9 and move downward; when the tension of alumina strip increases, roller frame 5 and inner guide roller 4 can move upward.

[0054] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims in this utility model, and no reference numerals in the claims should be regarded as limiting the content of the claims.
