Description

Technical Field

[0001] The invention relates to the technical field of quartz slab processing, and in particular to a quartz slab curing device. Background Art

[0002] In the production and processing of quartz slabs, curing is a crucial link. The curing process not only determines the physical properties and chemical stability of the quartz slabs, but also directly affects its final use effect and life. Traditional quartz slab curing devices generally achieve the curing of quartz slabs by passing hot air to keep the quartz slabs warm. This insulation method has the following shortcomings: The loading and unloading of quartz slabs is inconvenient. Since the interior of the curing device is usually filled with high-temperature hot air, operators need to be particularly careful when loading and unloading to avoid the risk of scalding. This not only increases the difficulty of operation, but also reduces production efficiency. The quartz stone slab is heated unevenly during the curing process, making it difficult to achieve uniform heat distribution, resulting in deformation, cracking and other problems after curing. Moreover, water is prone to accumulate on the side of the quartz stone slab that contacts the support platform, which is difficult to be removed by the hot air in time, affecting the curing quality of the quartz stone slab.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1: like Figures 1 to 5 As shown, the present invention provides a quartz slab curing device. The heat-insulating outer shell 1 is a closed box, and an air inlet pipe 11 and an air outlet pipe 12 are correspondingly connected to the left and right ends of the upper side of the heat-insulating outer shell 1, which are used to supply and exhaust air into and from the heat-insulating outer shell 1. The lower support plate 2 is installed in the heat-insulating outer shell 1, and is used to support the quartz slab 3. The upper pressing plate 4 is installed in the heat-insulating outer shell 1 for pressing on the quartz slab 3. The lower support plate 2 and the upper pressing plate 4 are both made of heat-conducting materials, which are used to insulate the quartz slab 3 and achieve the curing of the quartz slab 3. The lifting assembly 5 is connected between the upper pressing plate 4 and the heat-insulating outer shell 1, and is used to drive the upper pressing plate 4 to lift and lower, so that the upper pressing plate 4 switches between the upper working position and the lower working position, which is convenient for loading and unloading the quartz slab 3.

[0025] An air inlet channel 61 and an air outlet channel 64 corresponding to the air inlet pipe 11 and the air outlet pipe 12 are respectively arranged on the upper side of the left and right ends of the upper pressing plate 4. An air inlet cavity 62 is formed between the left end of the upper pressing plate 4, the left end of the lower support plate 2 and the left side wall of the heat-insulating shell 1, and an air outlet cavity 63 is formed between the right end of the upper pressing plate 4, the right end of the lower support plate 2 and the right side wall of the heat-insulating shell 1. An upper ventilation cavity 41 is provided on the upper pressing plate 4, which runs through the left and right ends of the upper pressing plate 4, and the two ends of the upper ventilation cavity 41 are connected to the air inlet cavity 62 and the air outlet cavity 63. A lower ventilation cavity 21 is provided on the lower support plate 2, which runs through the left and right ends of the lower support plate 2, and the two ends of the lower ventilation cavity 21 are connected to the air inlet cavity 62 and the air outlet cavity 63.

[0026] Work process; When the lifting assembly 5 drives the upper pressing plate 4 to rise to the upper working position, the left and right ends of the upper pressing plate 4 respectively block the air inlet channel 61 and the air outlet channel 64, so that the air inlet channel 61 is separated from the air inlet cavity 62, and the air outlet channel 64 is separated from the air outlet cavity 63; at this time, hot air cannot enter the heat-insulating housing 1, which is convenient for the operator to move the quartz slab 3 and place a new quartz slab 3 that needs to be cured, avoiding waste of hot air and scalding the operator; When the lifting assembly 5 drives the upper pressing plate 4 to descend to the lower working position, the air inlet channel 61 is connected with the air inlet cavity 62, the air outlet channel 64 is connected with the air outlet cavity 63, and the upper pressing plate 4 is pressed on the quartz stone plate 3, so that the upper pressing plate 4 and the lower supporting plate 2 are tightly attached to the two side surfaces of the quartz stone plate 3; the hot air passes through the air inlet pipe 11, the air inlet channel 61, and the air inlet cavity 62 in sequence, and then enters the upper ventilation cavity 41 of the upper pressing plate and the lower ventilation cavity 21 of the lower supporting plate 2 respectively, heating the upper pressing plate 4 and the lower supporting plate 2, thereby realizing the heat preservation of the quartz stone plate 3, and the upper pressing plate 4 and the lower supporting plate 2 are clamped on both sides of the quartz stone plate 3, which can ensure the flatness of the quartz stone plate 3 and avoid the solidification and deformation of the quartz stone plate 3; Finally, the hot air gathers in the air outlet cavity 63 and then flows back to the hot air source through the air outlet channel 64 and the air outlet pipe 12.

[0027] Recombination Figure 7 As shown, in this embodiment, a plurality of evenly distributed strip grooves are provided on the lower support plate 2, and elastic rubber strips 23 are installed in the strip grooves. The upper side of the elastic rubber strips 23 is semicircular and higher than the upper surface of the lower support plate 2. When the quartz stone plate 3 is placed, the elastic rubber strips 23 are supported under the quartz stone plate 3, and a gap is formed between the quartz stone plate 3 and the lower support plate 2.

[0028] In combination with the above working process, when the lifting assembly 5 drives the upper pressing plate 4 to descend to the lower working position, the upper pressing plate 4 provides a certain pressure on the quartz slab 3, so that the elastic rubber strip 23 is squeezed by the quartz slab 3, and then retracts into the strip groove on the lower support plate 2, ensuring that the upper pressing plate 4 and the lower support plate 2 are clamped on both sides of the quartz slab 3; During the heat preservation process, the lifting component 5 drives the upper pressing plate 4 to rise once at regular intervals, so that the upper pressing plate 4 is separated from the quartz stone plate 3, and the elastic rubber strip 23 bounces up the quartz stone plate 3, and a gap is re-formed between the quartz stone plate 3 and the lower supporting plate 2; at this time, the gaps on the upper and lower sides of the quartz stone plate 3 are connected to the air inlet cavity 62 and the air outlet cavity 63 on both sides, and the hot air will flow through the upper and lower sides of the quartz stone plate 3, taking away the water vapor on the upper and lower sides of the quartz stone plate 3, and improving the curing molding quality of the upper and lower sides of the quartz stone plate 3; then, the lifting component 5 drives the upper pressing plate 4 down to the lower working position again.

[0029] Embodiment 2: Based on the above embodiment 1, Figures 3 to 7 As shown, in order to better control the on-off and flow of hot air in the heat-insulating shell 1, the structures of the air inlet channel 61 and the air outlet channel 64 are symmetrical, and the structures of the air inlet cavity 62 and the air outlet cavity 63 are symmetrical.

[0030] Combination Figure 3 and Figure 5 As shown, the air intake channel 61 is taken as an example: The air inlet passage 61 includes an inverted U-shaped plate 611 fixed in the heat-insulating shell 1, the upper end of the U-shaped plate 611 is fitted with the heat-insulating shell 1, and the air inlet pipe 11 passes through the heat-insulating shell 1 and the U-shaped plate 611 and is connected to the inside of the U-shaped plate 611. The T-shaped plate 612 is fixed at the left end position of the upper side surface of the upper pressing plate 4, and the T-shaped plate 612 is slidably fitted with the right side surface of the U-shaped plate 611, and the right side surface of the U-shaped plate 611 is slightly lower than the left side surface of the U-shaped plate 611. When the lifting assembly 5 drives the upper pressing plate 4 to rise to the upper working position, the T-shaped plate 612 blocks the lower end of the U-shaped plate 611, so that the air inlet passage 61 is separated from the air inlet cavity 62. When the lifting assembly 5 drives the upper pressing plate 4 to descend to the lower working position, the T-shaped plate 612 opens the lower end of the U-shaped plate 611, so that the air inlet passage 61 is connected with the air inlet cavity 62.

[0031] Combination Figure 3 , Figure 5 and Figure 6 As shown, the air inlet cavity 62 is used as an example to illustrate: An air guide plate 621 opposite to the end of the upper pressing plate 4 is fixed in the air inlet cavity 62, and the air guide plate 621 guides the hot air to flow downward. A guide strip 622 is fixed on the air guide plate 621, and the guide strip 622 is opposite to the upper ventilation cavity 41 of the upper pressing plate 4, and is used to guide part of the hot air into the upper ventilation cavity 41. The upper ventilation cavity 41 is composed of a row of circular through holes evenly arranged on the upper pressing plate 4. The upper surface of the guide strip 622 is arc-shaped, and a row of evenly distributed ventilation grooves 6221 are arranged on the guide strip 622, and the ventilation grooves 6221 are staggered one by one with the circular through holes on the upper pressing plate 4. During operation, a part of the hot air enters the upper ventilation cavity 41 of the upper pressing plate 4 under the guidance of the guide strip 622, and then flows to the air outlet cavity 63, and another part of the hot air continues to flow downward through the ventilation grooves 6221.

[0032] Recombination Figure 7 As shown, the lower support plate 2 is fixed on the U-shaped support plate 7, and the lower side of the lower support plate 2 has evenly distributed heat dissipation fins 22, and a lower ventilation cavity 21 is formed between the heat dissipation fins 22 and the support plate 7. The hot air passing through the guide strips 622 downward will pass between the heat dissipation fins 22 and then flow to the air outlet cavity 63.

[0033] Combination Figure 1 and Figure 3 As shown, in this embodiment, the left and right side walls of the heat-insulating shell 1 are provided with bosses 13, respectively, and guide bars 14 are fixed on the bosses 13. The guide bars 14 are slidably supported on the ends of the support plate 7, and the support plate 7 can slide outward along the guide bars 14 for a distance, so as to facilitate the loading and unloading of the quartz stone plate 3. Correspondingly, a door opening is provided at the position opposite to the support plate 7 of the heat-insulating shell 1, and a sealing door 71 matching the door opening is fixed on the side of the support plate 7 close to the door opening, and a handle 72 is fixed on the outside of the sealing door 71. Sealing strips are fixed around the sealing door 71 to improve the sealing performance of the sealing door 71 when it is closed.

[0034] Embodiment three: Based on the above embodiments, Figures 3 to 5 As shown, the lifting assembly 5 includes a cylinder 51, which is fixed to the top of the heat-insulating shell 1, and the piston rod of the cylinder 51 is vertically downward. A guide sleeve 52 is fixedly connected to the center of the upper surface of the upper pressure plate 4, and the upper end of the guide sleeve 52 is sleeved on the piston rod of the cylinder 51. A guide groove 521 is provided on the side wall of the guide sleeve 52, and a pin 53 is fixed to the piston rod of the cylinder 51, and the two ends of the pin 53 are slidably inserted into the guide groove 521. A spring 54 is installed in the guide sleeve 52, and the spring 54 is pressed between the piston rod end of the cylinder 51 and the upper pressure plate 4.

[0035] When the cylinder 51 drives the upper pressure plate 4 to descend to the lower working position, the pin shaft 53 will slide downward for a distance, and the upper pressure plate 4 will be pressed downward by the spring 54, so the pressure on the quartz stone slab 3 is the weight of the upper pressure plate 4 and the elastic force of the spring 54, avoiding the problem that the cylinder 51 directly presses on the quartz stone slab 3, thereby causing the quartz stone slab 3 to be easily crushed.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
