Description

Technical Field

[0001] The utility model relates to the technical field of PET composite panel processing, in particular to drying equipment for PET composite panel processing. Background Art

[0002] The scientific name of PET is polyethylene terephthalate, which is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness, and has the greatest toughness among thermoplastics: good electrical insulation performance, little affected by temperature, but poor corona resistance; it is non-toxic, weather-resistant, and has good chemical resistance, low water absorption, and resistance to weak acids and organic solvents; PET composite panels need to be dried during the composite processing; existing drying equipment does not fix the composite panels when conveying them into the drying box, resulting in poor conveying effect and relatively low overall drying efficiency.

[0003] After searching, a drying equipment for processing PET composite panels disclosed in the prior art (Announcement No.: CN214605462U) records that "the equipment body is in a square structure as a whole, and a drying tank is provided in the equipment body.

Air port 14, and at the same time, the two sides of the inner cavity of the box body 1 are movably connected to the collecting box 15 through the guide plate 16, the lower surface of the shell body 2 is fixedly connected to the insulation box 4, and the insulation box 4 is fixedly connected to the heating component 5, and the insulation box 4 is connected to the inner cavity of the preheating plate 11 through the air supply pipe, and the bottom of the inner cavity of the box body 1 is symmetrically connected to the cylinder 8, and the multi-stage telescopic rod of the cylinder 8 is fixedly connected to the clamping component 7 through the through hole opened in the shell body 2, and the middle part of the inner cavity of the shell body 2 is fixedly connected to the limiting component 9, and at the same time, the bottom of the inner cavity of the shell body 2 is symmetrically provided with air outlet holes relative to the position of the insulation box 4.

[0019] In this embodiment, the PET composite panel to be dried is transported from the feed port to the inside of the shell 2, the switch of the motor in the roller assembly 3 is started, so that the roller assembly 3 can drive the PET composite panel to adjust its position inside the shell 2, the motor switch of the roller assembly 3 is turned off, and the switch of the cylinder 8 is started. The multi-stage telescopic rod of the cylinder 8 pushes the fixedly connected clamping assembly 7 to move upward, and the clamping assembly 7 pushes the PET composite panel to move upward synchronously, so that the limit assembly 9 can cooperate with the clamping assembly 7 to position and fix the PET composite panel in the middle of the inner cavity of the shell 2, and then the switches of the heating assembly 5 and the fan 10 are started in turn. The fan 10 injects the external airflow into the preheating plate 11, and the airflow in the preheating plate 11 is injected into the insulation box 4 through the air pipe. The heating assembly 5 in the insulation box 4 will perform corresponding heating treatment on the airflow passing through to make it hot air, and the hot air passes through The diversion of the air outlet of the shell 2 can be evenly sprayed onto the surface of the PET composite panel. When the hot air leaves the inner cavity of the shell 2 through the exhaust column 12, the hot air will fully contact the surface of the PET composite panel and can simultaneously bring out the generated moisture.

Therefore, when the airflow is discharged from the interior of the box 1 through the exhaust port 14, it can preheat the airflow flowing through the preheating plate 11 accordingly, thereby helping to reduce the energy consumption of the drying equipment and improve the heat recovery rate. After the PET composite panel is dried, the reset switch of the cylinder 8 is started, and the multi-stage telescopic rod of the cylinder 8 drives the clamping assembly 7 and the PET composite panel to reset synchronously. When the switch of the roller assembly 3 is started, the roller in the roller assembly 3 can push the PET composite panel out of the discharge port opened in the box 1.

[0020] As a preferred embodiment, feeding ports and discharging ports are respectively formed at two ends of the box body 1 corresponding to the inner cavity of the shell 2. The top of each of the feeding port and the discharging port is fixedly connected with a shielding curtain, and a blower 10 is fixedly connected to one end of the surface of the box body 1 close to the feeding port.

[0024] As a preferred embodiment, the upper surface of the shell 2 is convex in an arc shape. A plurality of air outlet holes uniformly formed at the bottom of the inner cavity of the shell 2 all have a cylindrical structure. The heat insulation box 4 fixedly connected to the lower surface of the shell 2 has a U-shaped cross section. At the same time, two through holes formed at both ends of the bottom of the inner cavity of the shell 2 are both rectangular in shape.

[0025] In this embodiment, as Figure 1 、 Figure 2 and Figure 4 , the arc-shaped structure of the upper surface of the shell 2 can guide the condensed water condensed on the upper surface of the shell 2 to flow towards the collecting boxes 15 on both sides. Then, the condensed water can be smoothly collected in the collecting boxes 15 for subsequent unified treatment.

The length of the partition plates 13 is smaller than the length of the preheating plate 11, and the width of the outer side of the preheating plate 11 is smaller than the width of the inner cavity of the box body 1.

[0027] In this embodiment, if Figure 1 and Figure 2 The setting of the partition plate 13 allows the airflow inside the preheating plate 11 to be evenly divided into multiple streams, which can then help improve the preheating effect of the hot and humid airflow on the airflow inside the preheating plate 11, improve the secondary recovery rate of heat by the drying equipment, and help reduce the energy consumption of the drying equipment.

[0029] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 The setting of the limiting component 9 can effectively limit the movement range of the PET composite panel inside the shell 2, and then ensure that the PET composite panel can be suspended in the middle of the inner cavity of the shell 2 with the cooperation of the clamping component 7, thereby effectively increasing the actual contact area between the airflow and the surface of the PET composite panel and improving the drying efficiency.

[0030] As a preferred embodiment, the clamping assembly 7 consists of a movable plate and a movable rod. The clamping assembly 7 as a whole has a U-shaped structure, and the two groups of movable plates are both long strip structures. The two ends of the lower surface of the movable plate are symmetrically connected to the two groups of guide rods 6. The guide rods 6 are slidably connected to the guide holes opened at the bottom of the inner cavity of the shell 2, and the multiple groups of movable rods fixedly connected between the two groups of movable plates are all cylindrical structures. At the same time, the movable rods and the limit rods are staggered.

[0031] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 The setting of the clamping component 7 enables the drying equipment to clamp and fix the PET composite panel accordingly, thereby avoiding the problem of accidental displacement and sliding of the PET composite panel during the drying process.
