Description

Technical Field

[0001] The invention relates to the field of foam box production, in particular to a drying device for foam box production. Background Art

[0002] Foam boxes are box-type packaging containers made of foam plastic. Plastic foam is a plastic with many tiny pores inside. Foam boxes are often used in the transportation of fruits and the packaging of items.

[0003] Foam boxes are usually made using molds and need to be immersed in water for cooling after demoulding. After cooling, the moisture on the surface needs to be dried. However, the foam boxes in the prior art are usually dried in a drying room and placed on a drying rack for drying. This method often has low drying efficiency, and the moisture on the surface of the foam box is retained at the bottom of the foam box due to inertia, resulting in poor drying effect and uneven surface stability, which causes the foam box to deform easily after cooling, increasing defective products. Summary of the invention

[0004] The purpose of the present invention is to provide a drying device for producing foam boxes.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A drying device for producing foam boxes, comprising a box body arranged on a machine platform, wherein a switch door is arranged on the side wall of the box body:

[0008] The fixing mechanism includes orifice plates located on both sides of the convex seat, wherein one end of the orifice plates is provided with a rack penetrating the convex seat, and a gear meshing with the two sets of racks is provided in the side wall of the convex seat between the two sets of racks, and the gear is driven by a motor I;

[0009] The drying mechanism I comprises a buffer cavity arranged in the convex seat, wherein a through hole communicating with the buffer cavity is arranged on the outer wall of the convex seat, and a fan is arranged in the through hole;

[0010] The drying mechanism II comprises a circle of blowing pipes which are covered on the convex seat, wherein nozzles are evenly arranged on the inner wall of the blowing pipe, and a convex block is also arranged on the outer wall of the blowing pipe, and a screw driven by the motor II is arranged on the convex block.

[0011] Preferably, a plurality of support rods are radially arranged on the outer wall of the boss below the orifice plate.

[0012] Preferably, a sliding channel for accommodating the corresponding rack to pass through is arranged on the side wall of the boss, wherein an accommodating cavity for accommodating the gear is also arranged in the side wall of the boss.

[0013] Preferably, the buffer chamber is connected to the heating chamber via a pipeline, and the blowing pipe is connected to the heating chamber via a corrugated hose.

[0014] Preferably, bearings for fixing the screw rod are provided on the side walls at both the upper and lower ends of the box body.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] A drying device for producing foam boxes, comprising a box body 2 arranged on a machine platform 1, wherein a switch door is arranged on the side wall of the box body 2:

[0023] A convex seat 3 is arranged on the top of the machine 1 in the box body 2, wherein a fixing mechanism 4 is arranged on the convex seat 3, a drying mechanism I5 is arranged in the side wall of the convex seat 3, wherein a drying mechanism II6 is arranged in the box body 2 outside the convex seat 3, and the drying mechanism I5 and the drying mechanism II6 are both connected to a heating chamber 7 arranged on the inner wall of the box body 1, and an air inlet pipe connected to a hot air blower is arranged on the heating chamber 7, wherein a heating plate 8 is also arranged in the heating chamber 7;

[0024] The fixing mechanism 4 includes orifice plates 41 located on both sides of the convex seat 3, and the top of the orifice plates 41 is higher than the horizontal plane of the top of the convex seat 3, wherein one end of the orifice plates 41 is provided with a rack 42 penetrating the convex seat 3, and a gear 43 meshing with the two sets of racks 42 is provided in the side wall of the convex seat 3, and the gear 43 is driven by a motor 144;

[0025] The drying mechanism 15 includes a cache cavity 51 disposed in the convex seat 3, wherein a through hole 52 communicating with the cache cavity 51 is disposed on the outer wall of the convex seat 3, and a fan 53 is disposed in the through hole 52;

[0026] The drying mechanism II6 includes a circle of blowing pipes 61 which are arranged on the convex seat 3, wherein nozzles 62 are evenly arranged on the inner wall of the blowing pipe 61, and a protrusion 63 is also arranged on the outer wall of the blowing pipe 61, and a screw rod 64 driven by a motor II65 is arranged on the protrusion 63, wherein bearings for fixing the screw rod 64 are arranged on the side walls at the upper and lower ends of the box body 2.

[0027] like Figure 1 , 2 As shown, a plurality of support rods 9 are radially arranged on the outer wall of the boss 3 below the orifice plate 41. When the foam box or box is buckled on the fixing mechanism 4 and the boss 3, the plurality of support rods 9 can suspend it in the air, so that the air between the inner and outer sides of the foam box can circulate through the space below the support rods 9.

[0028] In this embodiment, a sliding channel for accommodating the corresponding rack 42 is provided on the side wall of the boss 3 , wherein an accommodating cavity for accommodating the gear 43 is also provided in the side wall of the boss 3 .

[0029] In this embodiment, the buffer chamber 51 is connected to the heating chamber 7 through a pipeline, and the blowing pipe 61 is connected to the heating chamber 7 through a corrugated hose.

[0030] like Figure 1 , 2As shown in FIG. 3, when in use, the foam box or case is buckled on the fixing mechanism 4 and the convex seat 3 by opening the switch door and suspended by the support rod 9. At this time, the motor 144 drives the gear 43 to rotate and drives the rack 42 to slide in the sliding channel, thereby driving the orifice plate 41 to move outward, and by expanding the distance between the two groups of orifice plates 41, the two groups of orifice plates 41 are pressed against the inner wall of the foam box or case to support and fix it;

[0031] Then the hot air blower introduces the hot air into the heating chamber 7 and is heated again by the heating plate 8. At this time, a part of the hot air flow enters the buffer chamber 51 through the pipe and is discharged by multiple groups of through holes 52. At this time, the fan 53 can accelerate the circulation speed of the air flow in the through hole 52, and at the same time, it can also play a turbulent role, so that the air flow passes through the side wall holes of the orifice plate 41 or blows directly to the inner wall of the foam box or box, thereby drying the inside thereof. Finally, the gas flows out through the gap between the foam box or box and the top of the machine 1, and at the same time, another part of the hot air flow in the heating chamber 7 enters the blowing pipe 61 through the corrugated hose and is sprayed by the nozzle 62, thereby drying the outer wall of the foam box or box. At this time, the motor II65 drives the screw 64 to rotate in the screw hole on the protrusion 63, thereby driving the blowing pipe 61 and the nozzle 62 to move back and forth up and down on the outside of the foam box or box, thereby achieving a drying effect on different upper and lower areas of the outside of the foam box or box.

[0032] The present invention supports and fixes the foam box or box through the fixing mechanism 4 to prevent it from being deformed during the drying process, and simultaneously dries the inside and outside of the foam box or box through the drying mechanism I5 and the drying mechanism II6 to improve the drying efficiency and effect, wherein the heating chamber 7 can not only be used to reheat the gas and supply hot air flow to the drying mechanism I5 and the drying mechanism II6, but also effectively insulate the side walls of the box body 2 to prevent the internal heat from volatilizing quickly through the side walls.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
