[0003] Hot -blast circulating oven includes conveying belt, carbon paper is placed on the conveying device, the conveying process of carbon paper in hot -blast circulating oven is just realized drying work, due to the light weight of carbon paper, the large amount of air in drying process, it can not be positioned on the transmission device, thereby increasing the working difficulty of drying process. UTILITY MODEL CONTENT
[0004] The utility model discloses a kind of carbon paper limiting devices for hot -blast circulating oven, its advantage is that the pressing effect to carbon paper can be effectively realized, so that carbon paper is smoothly dried in hot -blast circulating oven.
[0005] The above technical purpose of the utility model is realized by the following technical scheme: a kind of carbon paper limiting device for hot -blast circulating oven, including lower bottom plate and upper pressing plate, the lower bottom plate and upper pressing plate are all equipped with full equivalent through slot, the upper pressing plate is equipped with lock catch mechanism, the lock catch mechanism includes the fixed block parallel with upper pressing plate, the bottom of the fixed block is fixedly provided with multiple vertical sliding rods with the fixed block, the sliding rod is all slidably arranged in upper pressing plate, the bottom of the fixed block is fixedly provided with connecting spring, the upper pressing plate is equipped with the limiting through-hole for connecting spring to penetrate, the fixed block is slidably buckled with the limiting plate parallel with upper pressing plate, the lower bottom plate is equipped with extension block, the extension block is equipped with the limiting slot for the embedding of limiting plate.
[0006] The utility model is further provided as follows: the lower bottom plate is equipped with the positioning storage groove for embedding connecting spring.
[0007] The utility model is further provided as follows: the upper surface of the lower bottom plate is fixedly provided with ultrafine fiber nonwoven layer close to through slot.
[0008] The utility model is further provided as follows: the lower bottom plate is arrayed with multiple exhaust micropores at the coverage of ultrafine fiber nonwoven layer.
[0009] As described above, the utility model has the following beneficial effects:
[0010] 1. The overlap of the lower base plate and the upper pressure plate of this limiting device realizes the pressing and limiting of the carbon paper. Then, the connection between the lower base plate and the upper pressure plate is realized through the locking mechanism, which further ensures the pressing of the carbon paper, so that the carbon paper can be dried smoothly in the hot air circulating oven.
[0011] 2. The locking mechanism includes a connecting spring. After the connection between the upper pressure plate and the lower base plate is removed, there is a certain space between the upper pressure plate and the lower base plate under the action of the connecting spring. Compared with two completely overlapping plates, this method makes it easier for workers to quickly remove the upper pressure plate from the lower base plate so that the carbon paper can be put in, thereby effectively improving work efficiency.
[0012] 3. The bottom plate is equipped with a positioning and storage slot for the connecting spring, which makes it easy for workers to quickly find the positional relationship between the upper pressure plate and the bottom plate, accurately achieve the overlap of the upper pressure plate and the bottom plate, and effectively improve work efficiency.
[0013] 4. The bottom of the lower base plate is equipped with a support disc foot to ensure that the limiting device can be placed stably on the conveyor belt of the hot air circulating oven, while avoiding contact between the lower base plate and the conveyor belt. That is, there is a certain height difference between the lower base plate and the conveyor belt, so that the staff can use this height difference to quickly pick up the limiting device from the conveyor belt.
[0014] 5. A microfiber nonwoven fabric layer is installed on the bottom plate. On the one hand, it can provide flexible support for the carbon paper, which can prevent the carbon paper from being damaged by the locking mechanism of the upper pressure plate and the bottom plate, thus avoiding wear and tear on the carbon paper. It can also prevent the carbon paper from being ineffectively limited due to gaps between the upper and lower plates caused by material itself, surface roughness, or process issues. On the other hand, the microfiber nonwoven fabric layer has the advantages of being soft, delicate, and smooth, and is not easy to scratch sensitive materials. When it comes into contact with the carbon paper, the friction is low, which can reduce the risk of damage. In addition, microfiber nonwoven fabric also has the advantage of no fiber shedding. In particular, high-quality microfiber fabric does not shed lint, which can prevent the carbon paper's micropores from being blocked when in contact with it.
[0015] 6. The microfiber nonwoven fabric layer also has a good moisture absorption effect. When the carbon paper is clamped and positioned between the top plate and the bottom plate, its periphery will inevitably be blocked, resulting in poor drying effect on the periphery of the carbon paper. At this time, the microfiber nonwoven fabric layer can play a moisture absorption role on its periphery. That is, during the drying process in the dryer, the presence of the exhaust micropores set in the bottom plate can form a hot airflow channel between the microfiber nonwoven fabric layer and the carbon paper, effectively realizing the drying effect on the clamped part of the carbon paper, and avoiding damage and defective products.

[0030] Example: A carbon paper limiting device for a hot air circulating oven, such as Figure 1 As shown, the device includes a lower base plate 1 and an upper pressure plate 2. Both the lower base plate 1 and the upper pressure plate 2 are provided with equal through slots 3. The upper pressure plate 2 of this limiting device is provided with four locking mechanisms 4, which are evenly distributed near the four corners of the upper pressure plate 2. Figures 2-4 As shown, the locking mechanism 4 includes a fixed block 41 parallel to the upper pressure plate 2. Multiple sliding rods 42 perpendicular to the fixed block 41 are fixedly mounted on the bottom of the fixed block 41. The sliding rods 42 are all slidably disposed within the upper pressure plate 2. That is, the fixed block 41 is connected to the upper pressure plate 2 via the sliding rods 42 and can slide up and down with the connecting rods. A connecting spring 43 is fixedly mounted on the bottom of the fixed block 41. The upper pressure plate 2 has a limiting through hole 44 through which the connecting spring 43 passes. Simultaneously, the lower base plate 1 is positioned at a corresponding location... A positioning storage groove 11 is provided for the connecting spring 43 to be embedded. That is, after the connecting spring 43 passes through the limiting through hole 44 of the upper pressure plate 2, it can be stored in the positioning storage groove 11 of the lower base plate 1 to reduce the overlap gap between the upper pressure plate 2 and the lower base plate 1. A limiting plate 45 parallel to the upper pressure plate 2 is also slidably embedded in the fixing block 41 of each locking mechanism 4, and an extension block 46 is fixedly provided on the shorter side of the lower base plate 1. The extension block 46 is provided with a limiting groove 47 for the limiting plate 45 to be embedded.
[0031] Specific implementation: the carbon paper 7 to be dried is placed on the upper surface of the lower base plate 1, and then the upper pressing plate 2 is overlapped with the lower base plate 1 to realize the pressing limiting of the carbon paper 7, in the process, under the action of the connecting springs 43, the workers embed the connecting springs 43 into the positioning storage grooves 11 of the lower base plate 1, which quickly locates the overlapping position between the upper pressing plate 2 and the lower base plate 1, after the upper pressing plate 2 is completely overlapped with the lower base plate 1, the workers press each fixing block 41 downward in turn, so that the lower surface of the fixing block 41 is in abutment with the upper pressing plate 2, then the workers slide the limiting plate 45 to embed it into the limiting groove 47 of the extension block 46, to realize the locking connection between the upper pressing plate 2 and the lower base plate 1, and to realize the limiting of the carbon paper 7, at this time, the limiting device can be placed on the conveying belt of the hot air circulating oven to realize the drying of the carbon paper 7.
[0032] In the embodiment, as shown in Figure 2 and 3 , the upper surface of the lower base plate 1 is fixedly provided with a superfine fiber non-woven fabric layer 5, which plays a flexible supporting role for the carbon paper 7, avoids the damage of the carbon paper 7 caused by the locking action of the locking mechanism 4 between the upper pressing plate 2 and the lower base plate 1, and causes the wear of the carbon paper 7, and the superfine fiber non-woven fabric layer 5 can be made of polyamide superfine fiber cloth; as shown in Figure 2 and 3 , four supporting disc feet 12 are uniformly arranged at the bottom of the lower base plate 1, which not only ensures that the limiting device can be stably placed on the conveying belt of the hot air circulating oven, but also avoids the contact between the lower base plate 1 and the conveying belt, that is, there is a certain height difference between the lower base plate 1 and the conveying belt, which facilitates the workers to quickly pick up the limiting device from the conveying belt by using the height difference.
[0033] In the embodiment, as shown in Figure 5 , a plurality of exhaust micro-holes 6 are uniformly arranged in an array at the position covered by the superfine fiber non-woven fabric layer 5, and the diameter of the exhaust micro-holes is 1-2mm, in the embodiment, the exhaust micro-holes 6 with a diameter of 1.5mm are adopted, since there are four supporting disc feet 12 at the bottom of the lower base plate 1, that is, there is a height difference between the lower base plate 1 and the conveying belt, at this time, the exhaust micro-holes 6 arranged on the lower base plate 1 can form a hot drying air flow channel between the superfine fiber non-woven fabric layer 5 and the carbon paper 7, which effectively realizes the drying effect of the clamped part of the carbon paper 7, and avoids the damage and unqualified product situation.
[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
