Description

Technical Field

[0001] The utility model relates to the technical field of artificial board production, in particular to an air cooling device for artificial boards. Background Art

[0002] Wood-based panels are made from wood or other non-wood plant materials. After mechanical processing, they are separated into various component materials and then bonded together with or without adhesives and other additives. These primarily include three categories: plywood, particleboard, and fiberboard. Hundreds of further products and further processed products are also available.

[0003] In the production process of artificial boards, a hot pressing process is usually required. The temperature of the boards after the hot pressing process is very high and they need to be cooled before entering the next process. The cooling efficiency of traditional natural air cooling is low and it has been rarely used. An existing air cooling device adopts a method of cooling the boards while conveying. The conveyed boards pass through a cooling box, and cold air is blown to the boards in the cooling box. Due to the problem of air volume distribution, this air cooling device is prone to low local cooling temperature of the boards and rapid cooling of the boards, which leads to a decrease in the performance of the boards and may cause defects in appearance. Utility Model Content

[0004] In response to the problems existing in the prior art, the utility model provides an air cooling device for artificial panels, which can gradually cool the panels, avoid the phenomenon of low local cooling temperature of the panels and rapid cooling of the panels, and improve the cooling effect and efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air-cooling device for artificial boards, comprising a conveying mechanism and a cooling box, the conveying mechanism having a conveying surface for conveying boards, the conveying surface passing horizontally through the cooling box, a sieve plate for uniform air distribution being provided in the cooling box, the sieve plate being arranged horizontally above the conveying surface, the sieve plate dividing the cooling box into an upper zone and a lower zone, a cold air inlet being arranged at one end of the upper zone, the direction in which the cold air enters the upper zone through the air inlet is opposite to the conveying direction of the conveying surface, and the aperture of the sieve holes on the sieve plate gradually decreases along the air inlet direction.

[0006] As a preferred embodiment of the present technical solution, the sieve plate is provided with a driving mechanism for causing the sieve plate to move back and forth laterally.

[0007] As a preferred embodiment of the present technical solution, the driving mechanism includes a motor, a cam and a buffer spring. The motor and the cam are arranged on the outside of the cooling box corresponding to one end of the sieve plate. The sieve plate at this end passes through the cooling box. The output end of the motor is connected to the cam to drive the cam to hit the sieve plate. The buffer spring is arranged in a groove on the inner wall of the cooling box corresponding to the other end of the sieve plate. The sieve plate at this end is inserted into the groove and presses against the buffer spring.

[0008] As a preferred embodiment of the present technical solution, openings are provided at both ends of the cooling box, the conveying surface passes through the cooling box through the openings, and a plate limiting mechanism is provided at the openings.

[0009] As a preferred embodiment of the present technical solution, the plate limiting mechanism includes a support plate and a limiting roller symmetrically arranged on both sides of the opening. The support plate slides within the side wall of the opening and is fixed by bolts and nuts. The limiting roller rotates vertically on the inner side of the support plate.

[0010] As a preferred embodiment of the present technical solution, the conveying device is a roller conveyor.

[0011] As a preferred embodiment of the present technical solution, an air outlet is provided at the lower end of the cooling box, and the air outlet is connected to a cold air collecting mechanism.

[0012] Compared with the prior art, the utility model, when the plates are conveyed into the cooling box, the cold air is conveyed to the upper area through the air inlet and blown downwards toward the plates on the conveying surface through the sieve holes of the sieve plate. Since the aperture of the sieve holes on the sieve plate gradually decreases along the air inlet direction, the amount of cold air where the plates just enter the cooling box is small, and the plates are gradually cooled. In addition, the driving mechanism drives the sieve plate to move back and forth laterally, and the downward cold air also moves back and forth downward, and the cold air does not blow directly toward the plates, thereby improving the uniformity of cooling of the plates; as the plates continue to be conveyed, the aperture of the sieve holes on the sieve plate also gradually increases, and the plates are cooled rapidly, from gradual cooling to rapid cooling, avoiding the phenomenon of low local cooling temperature of the plates and rapid cooling of the plates, thereby improving the cooling effect and efficiency.

[0018] See also Figure 1-3 The utility model discloses an air cooling device for artificial boards, comprising a conveying mechanism 1 and a cooling box 2. The conveying mechanism 1 has a conveying surface for conveying boards, and the conveying surface passes through both ends of the cooling box 2 horizontally. A sieve plate 3 for uniform air is provided in the cooling box 2. The sieve plate 3 is arranged horizontally above the conveying surface. Both ends of the sieve plate 3 are arranged on the side walls at both ends of the cooling box 2, that is, the sieve plate 3 is parallel to the conveying surface. The sieve plate 3 divides the cooling box 2 into an upper zone and a lower zone. An air inlet 1.1 for cold air is arranged at one end of the upper zone. The direction in which the cold air enters the upper zone through the air inlet 1.1 is opposite to the conveying direction of the conveying surface. The aperture of the sieve holes 3.1 on the sieve plate 3 gradually decreases along the air inlet direction.

[0019] When the utility model is implemented, the sieve plate 3 is provided with a driving mechanism that enables the sieve plate 3 to move back and forth laterally.
