Description

Technical Field

[0001] The utility model relates to a belt-covered hot air circulation acrylic softening furnace. Background Art

[0002] Since acrylic is not very hard and is easily scratched, the surface must be hardened. This process is called acrylic surface hardening treatment. After the acrylic plate is hardened, it needs to be dried in a high-temperature oven. In the prior art, when drying acrylic plates, most of the air in the oven is heated by electric heating wires, and then the heated air is used to statically dry the acrylic plate. Since the static air has poor fluidity and a small contact area with the acrylic plate, the drying efficiency of the acrylic plate is slow.

[0003] Existing ovens with high drying efficiency, for example, an acrylic plate drying oven with patent number CN221245943U, include a box body, a cover body connected to the top of the box body inner cavity, a heating wire connected to the box body is arranged on the inside of the cover body, an air circulation mechanism is arranged between the box body inner cavity and the cover body inner cavity, and a plurality of air outlets are opened at the bottom of the cover body; wherein the air circulation mechanism draws air in the box body into the cover body to be heated by the heating wire, and then is discharged into the box body again through the air outlet.

[0004] This embodiment can increase the contact area between the air and the electric heating wire and speed up the heating efficiency of the box air, but it has the following defects:

[0005] 1. The acrylic sheet is placed inside the box for drying, and needs to be taken out and put in constantly, which can easily destroy the stability of the drying environment;

[0006] 2. The air outlet is only set at the upper end, and the upper and lower ends of the acrylic plate cannot be dried at the same time, resulting in uneven drying. Summary of the invention

[0007] The utility model aims to solve one of the technical problems existing in the prior art.

[0008] The present application provides a belt-type hot air circulation acrylic softening furnace, comprising a box body, a heating wire and an air circulation mechanism, and also comprising:

[0009] A transport unit, which is arranged inside the box;

[0010] Among them, the transport unit drives the products through the interior of the box in sequence.

[0016] Also includes:

[0017] A number of connecting cavities, which are evenly distributed on the wire mesh;

[0018] A plurality of teeth are distributed in a ring shape on the outer wall of each roller;

[0019] Among them, all the connecting cavities are engaged with the corresponding teeth in sequence.

[0020] The air circulation mechanism includes:

[0021] A blower, which is mounted at the back end of the box;

[0046] Furthermore, the transport unit 4 includes a support frame 5, which is fixedly installed inside the box body 1, and its two ends pass through both sides of the box body 1; a pair of rotating shafts 6, which are rotatably installed on the support frame 5 and driven by a motor; a plurality of rollers 7, which are evenly distributed on each rotating shaft 6; and a wire mesh 8, which is movably connected between the pair of rotating shafts 6.

[0047] Furthermore, it also includes a plurality of connecting cavities 9, which are evenly distributed on the wire mesh 8; a plurality of teeth 10, which are distributed in a ring shape on the outer wall of each roller 7; wherein, each connecting cavity 9 is engaged with the corresponding tooth 10 in sequence.

[0048] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the acrylic plate to be dried is placed on the wire mesh 8, the motor drives the rotating shaft 6 on one side to rotate, and the other side is rotatably installed on the bracket frame through the bearing. Since the wire mesh 8 is sleeved between a pair of rotating shafts 6, the rotating shaft 6 on one side can drive the rotating shaft 6 on the other side to rotate at the same time, the wire mesh 8 drives the acrylic plate to pass through the inside of the box 1, and the box 1 performs a drying operation on the acrylic plate. The wire mesh 8 is evenly distributed with connecting cavities 9. While rotating, the rotating shaft 6 drives the roller 7 to rotate together, and the connecting cavity 9 will be clamped on the corresponding tooth 10 to ensure the driving stability of the wire mesh 8, and the setting of the connecting cavity 9 is convenient for the upward and downward circulation of the drying gas.

[0049] Embodiment 2:

[0050] like Figure 2 , Figure 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: the air circulation mechanism 3 includes a blower 11, which is installed at the back end of the box body 1; a front cover body 12, which is installed inside the box body 1 and connected to the fan output end; a pair of air outlet scoops 13, which are respectively fixedly connected in the front cover body 12; wherein, the pair of air outlet scoops 13 are set at two locations; a pair of air outlet scoops 13, which are respectively relatively set at the upper and lower sides of the wire mesh 8.

[0051] Furthermore, it also includes a plurality of air outlets 14 which are evenly distributed at the output end of the air outlet scoop 13 .

[0052] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the acrylic sheet enters the interior of the box body 1, the electric heating wire 2 is heated, and the blower 11 is started, so that the gas is heated, and the heated gas flows from the back end of the box body 1 along the outer cover of the blower 11 to the front cover body 12, and the heat energy inside the front cover body 12 flows from both sides to a pair of air outlet scoops 13 at both ends. The pair of air outlet scoops 13 are arranged up and down, respectively located above and below the wire mesh 8, and the output ends of the air outlet scoops 13 are both facing the wire mesh 8. The heat energy is dried on the acrylic sheet on the wire mesh 8 through each air outlet 14, ensuring that the positive side of the acrylic sheet can receive the drying operation and ensuring the uniformity of the drying effect.

[0053] Embodiment 3:

[0054] like Figure 1 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a control box 15, which is fixedly connected to one side of the box body 1; a temperature controller 16, which is installed in the control box 15; and a control button 17, which is adjustably installed on the control box 15.

[0055] Furthermore, the control button 17 includes a main circuit breaker switch 1701 , a blower switch 1702 , a heater switch 1703 and a motor switch 1704 .

[0056] In this embodiment of the present application, due to the adoption of the above-mentioned structure, a control box 15 is provided on one side of the box body 1. The control box 15 enables the box body 1 to be automated and is controlled and adjusted through the control button 17. First, the main circuit breaker switch 1701 is turned on to ensure that the box body 1 is powered on, and then the heater switch 1703 and the blower switch 1702 are turned on to drive the heating wire and the blower 11. The interior of the box body 1 is preheated for 30 minutes, and then the motor switch 1704 is turned on. The motor drives the rotating shaft 6 to rotate, so that the wire mesh 8 drives the acrylic plate to enter the interior of the box body 1 for drying. The temperature measuring probe connected to the temperature controller 16 is located in the front cover 12, which is convenient for detecting the drying temperature inside the box body 1, thereby adjusting the required temperature.
