Drying device with ventilation structure

Abstract

This utility model relates to a drying device with a ventilation structure. The upper and lower support plates of its support frame are densely covered with ventilation holes, breaking through the airflow obstruction of traditional solid support plates. This allows hot air to circulate without dead zones within the drying chamber, directly acting on the upper and lower surfaces and internal gaps of the copper-clad laminate roll material. This ensures uniform heating of the roll material and avoids localized over-curing or incomplete drying. The ventilation holes also accelerate heat exchange between the hot air and the roll material, allowing the hot air to penetrate the roll material more quickly, shortening drying time, improving production efficiency, reducing ineffective equipment operation, lowering energy consumption, and helping enterprises control costs and enhance competitiveness. The upper support plate can move up and down and is fixed by locking components. Operators can adjust the support plate spacing according to the height of the roll material: increasing the spacing for taller rolls ensures ventilation, while decreasing the spacing for shorter rolls improves space utilization, optimizing the drying capacity per batch. This adjustable structure significantly improves the equipment's versatility, adapting to different specifications of roll materials, meeting diverse production needs, and reducing equipment replacement or modification costs.

Description

Technical Field

[0001] This utility model relates to the field of drying device technology, and in particular to a drying device with a ventilation structure. Background Technology

[0002] Drying is a crucial step in the production and processing of copper-clad laminates (CCLs). Currently, the industry primarily uses traditional hot air circulating ovens for drying CCL coils. However, these traditional devices have the following shortcomings in practical applications: 1. Traditional ovens typically only have simple racks on which the CCL coils are placed directly. Since the racks are often solid, hot air circulation within the oven can easily create dead zones, leading to uneven heating at the top and bottom of the coil and at different locations. 2. To compensate for uneven heating, traditional drying processes often require extending the overall drying time to ensure that low-temperature areas reach the drying standard. This not only reduces production efficiency but also causes the equipment to operate at full capacity for extended periods, significantly increasing energy consumption. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a drying device with a ventilation structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A drying device with a ventilation structure includes a hot air circulating oven body, a drying chamber inside the hot air circulating oven body, and a support frame placed inside the drying chamber. The support frame is used to place objects to be dried. The support frame includes four columns and an upper support plate and a lower support plate connected between the four columns. The surfaces of the upper support plate and the lower support plate are densely covered with a number of through ventilation holes. The lower support plate is fixed at the lower end of the four columns. The upper support plate can move up and down between the four columns and is locked by a locking component.

[0006] In some embodiments, vertical grooves are provided on all four columns, and sliders are provided at the four corners of the upper support plate, with each slider corresponding to slide within the vertical groove.

[0007] In some embodiments, the locking assembly includes a locking rod, the slider is provided with a locking hole, and a plurality of through holes are provided through the vertical slide groove. The plurality of through holes are evenly distributed and spaced apart vertically, and the locking rod passes through the through holes and is inserted into the locking hole.

[0008] In some embodiments, the support frame further includes an X-shaped reinforcing block, the four outer ends of which are respectively connected to the four columns.

[0009] In some embodiments, a transverse connecting rod is connected between the two rear columns.

[0010] In some embodiments, both the upper support plate and the lower support plate are provided with a plurality of limiting components for limiting the position of the dried material.

[0011] In some embodiments, each of the limiting components includes a limiting rod spaced apart on the left and right sides, and both ends of the limiting rod are provided with a first engaging groove that can be engaged with the edge of the upper support plate or the lower support plate.

[0012] In some embodiments, a plurality of limiting zones are provided between the two limiting long rods, the plurality of limiting zones are spaced apart in the front-back direction, and each limiting zone is formed by two limiting short rods spaced apart in the front-back direction.

[0013] In some embodiments, the left and right ends of the limiting short rod are provided with second locking grooves, and the two second locking grooves are correspondingly locked onto the two limiting long rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The upper and lower support plates of the support frame are densely covered with through ventilation holes. This structure can break the airflow obstruction of traditional solid support plates, so that hot air can circulate without dead corners in the drying chamber. Hot air can directly act on the upper and lower end faces and internal gaps of the copper-clad laminate roll through the ventilation holes, ensuring that all areas of the roll are heated evenly, effectively avoiding the problems of local over-curing or incomplete drying.

[0016] 2. The design of the ventilation holes accelerates the heat exchange efficiency between hot air and copper-clad laminate rolls. Compared with traditional solid support plates, hot air can penetrate into the rolls more quickly, shortening the overall drying time and improving production efficiency per unit time. At the same time, efficient heat exchange reduces the ineffective operating time of equipment, lowers energy consumption, and helps companies control production costs while increasing production capacity, thereby enhancing market competitiveness.

[0017] 3. The upper support plate features a movable design and is fixed in position using locking components. Operators can flexibly adjust the distance between the upper and lower support plates according to the height of the copper-clad laminate roll. For taller rolls, the distance can be increased to ensure ventilation space, allowing the roll to be placed on either the upper or lower support plate. For shorter rolls, the distance can be reduced to improve space utilization, allowing the roll to be placed on both the upper and lower support plates simultaneously, optimizing the drying capacity per cycle. This adjustable structure greatly enhances the equipment's versatility, enabling rapid adaptation to different specifications of copper-clad laminate rolls, meeting diverse production scheduling needs of enterprises, and reducing the cost of equipment replacement or modification.

[0023] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0024] The following figures and detailed embodiments further describe the present invention: Figures 1-5 The drying device shown includes a hot air circulating oven body 1, a drying chamber 2 inside the hot air circulating oven body 1, and a support frame 3 placed inside the drying chamber 2. The support frame 3 is used to place objects to be dried. The support frame 3 includes four columns 4 and an upper support plate 5 and a lower support plate 6 connected between the four columns 4. The surfaces of the upper support plate 5 and the lower support plate 6 are densely covered with a number of ventilation holes 7. The lower support plate 6 is fixedly located at the lower end of the four columns 4. The upper support plate 5 can move up and down between the four columns 4 and is locked by a locking component.

[0025] When the hot air circulating oven body is started, the internal heating and air supply system of the equipment starts to work, and the generated hot air enters the drying chamber 2. Since the upper support plate 5 and the lower support plate 6 of the support frame 3 are densely covered with through ventilation holes 7, the hot air can break through the obstruction of the traditional solid support plate and form a multi-path flow.

[0026] The design of the ventilation holes 7 accelerates the heat exchange efficiency between the hot air and the copper-clad laminate roll 11. Compared with traditional solid support plates, the hot air can penetrate into the roll more quickly, shortening the overall drying time and improving the production efficiency per unit time. At the same time, the efficient heat exchange reduces the ineffective operating time of the equipment, reduces energy consumption, and helps companies control production costs and enhance market competitiveness while increasing production capacity.

[0027] In addition, the upper support plate 5 is designed to move up and down and is fixed in position by locking components. Operators can flexibly adjust the distance between the upper support plate 5 and the lower support plate 6 according to the height of the copper clad laminate roll 11. For taller rolls, the distance can be increased to ensure ventilation space, so that the roll can be placed on the upper support plate 5 or the lower support plate 6. For shorter rolls, the distance can be reduced to improve space utilization. The roll can be placed on both the upper support plate 5 and the lower support plate 6 at the same time to optimize the drying capacity per batch. This adjustable structure greatly improves the versatility of the equipment, can quickly adapt to copper clad laminate rolls of different specifications, meet the diverse production scheduling needs of enterprises, and reduce the cost of equipment replacement or modification.

[0028] See Figures 2-4 As shown, vertical grooves 21 are provided on all four columns 4, and sliders 22 are provided at the four corners of the upper support plate 5. Each slider 22 slides in the vertical groove 21.

[0029] Furthermore, the locking assembly includes a locking rod 31, a locking hole 32 is provided on the slider 22, and a plurality of through holes 33 are provided through the vertical slide groove 21. The plurality of through holes 33 are evenly distributed and spaced along the vertical direction, and the locking rod 31 passes through the through hole 33 and is inserted into the locking hole 32.

[0030] When adjusting the height of the upper support plate 5 according to the height of the copper clad laminate roll 11, first pull the locking rod 31 out of the currently inserted through hole 33 and locking hole 32 to release the fixation of the upper support plate 5; then push the upper support plate 5 along the vertical slide 21, and use the guide cooperation between the slider 22 and the slide 21 to move the upper support plate 5 to the target height that matches the height of the roll; during this process, the through holes 33 evenly distributed vertically on the vertical slide 21 provide multiple optional nodes for the locking position. The operator can select the through hole 33 that is aligned with the locking hole 32 on the slider 22 according to actual needs to complete the initial alignment of the locking position.

[0031] Once the locking hole 32 on the slider 22 is fully aligned with the target through hole 33 on the vertical slide groove 21, the locking rod 31 is inserted into the through hole from the outside of the slide groove and passes through into the locking hole 32 of the slider 22. Because the locking rod 31 fits tightly with the through hole 33 and the locking hole 32, it forms a rigid constraint after insertion, restricting the movement of the slider 22 along the vertical slide groove 21. Simultaneously, the slide groove provides lateral limiting for the slider, ensuring stable fixation of the upper support plate at the target height. To further improve locking reliability, a locking rod with anti-slip texture or a positioning pin can be selected to prevent the locking rod from loosening due to vibration during equipment operation.

[0032] See Figure 3 As shown, the support frame 3 also includes an X-shaped reinforcing block 41, the four outer ends of which are respectively connected to the four columns 4; the four outer ends of the X-shaped reinforcing block 41 are respectively connected to the four columns 4 to form a cross-type reinforcement structure.

[0033] Furthermore, a horizontal connecting rod 51 is connected between the two rear columns 4, thereby further strengthening the support frame 3.

[0034] In this invention, both the upper support plate 5 and the lower support plate 6 are provided with a number of limiting components for limiting the position of the dried material.

[0035] Furthermore, each of the limiting components includes a limiting long rod 71 spaced apart on the left and right. Both ends of the limiting long rod 71 are provided with a first engaging groove 72 that can be engaged with the edge of the upper support plate 5 or the lower support plate 6. A plurality of limiting areas 81 are provided between the two limiting long rods 71. The plurality of limiting areas 81 are spaced apart in the front-back direction. Each limiting area 81 is formed by two limiting short rods 82 spaced apart in the front-back direction.

[0036] It should be noted that the above-mentioned limiting components are for roll materials, such as copper-clad laminate roll 11, wherein the copper-clad laminate roll 11 is wound on the fixed cylinder 10, and then the fixed cylinder 10 is limited by the limiting components.

[0037] Before operation, first install the limiting rod 71 on the upper support plate 5 or the lower support plate 6. Using the first locking grooves 72 at both ends of the limiting rod 71, the rod is secured to the front and rear edges of the support plate. The first locking grooves 72 and the edges of the support plate form a tight engagement, preventing the rod from shifting laterally. Then, between the two limiting rods 71, several sets of limiting short rods (each set consisting of two short rods spaced apart front to back) are arranged at intervals along the front-back direction, forming multiple independent limiting zones 81. The front-back spacing of each limiting zone 81 is determined according to the diameter of the fixed cylinder 10, ensuring that after the fixed cylinder 10 is placed, the two front and rear limiting short rods 82 and the two left and right limiting rods 71 ​​can block it from the radial direction, preventing the fixed cylinder 10 from sliding.

[0038] Furthermore, each of the left and right ends of the limiting short rod 82 is provided with a second locking groove 91, and the two second locking grooves 91 are correspondingly locked onto the two limiting long rods 71.

[0039] When installing the limiting short rod 82, align the second locking grooves 91 at its left and right ends with the side walls of the two limiting long rods 71, and insert the short rod into the long rod in a direction perpendicular to the long rod. The second locking grooves 91 and the surface of the limiting long rod 71 form a tight engagement, and the limiting short rod can be quickly positioned without the need for additional bolts or welding.

[0040] In practical applications, this patented structure can not only efficiently dry copper-clad laminate rolls fitted outside the fixed cylindrical tube 10, but also adapt to the drying needs of various types of items by flexibly adjusting the spacing of the upper support plates of the support frame and the size of the limiting area of ​​the limiting components (such as adjusting the spacing of the long limiting rods and the spacing of the short limiting rods) according to the shape and size characteristics of different items.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
