Description

Technical Field

[0001] This utility model relates to the field of ABS plastic sheet drying technology, and in particular to a hot air circulating drying oven for ABS plastic sheets. Background Technology

[0002] ABS sheet is a relatively new material in the sheet industry. Its full name is acrylonitrile butadiene styrene copolymer sheet. It is the polymer with the largest production volume and widest application. It organically combines the various properties of PS, SAN, and BS, possessing excellent mechanical properties with a balance of toughness, hardness, and rigidity. However, ABS plastic sheets require drying in certain situations, such as when they have absorbed a lot of moisture during storage or transportation, or when processing requirements are high and moisture sensitivity is significant. Drying can remove moisture and prevent defects such as bubbles and silver streaks in subsequent processing. However, current drying efficiency for ABS plastic sheets is relatively low. Therefore, we have introduced a new hot air circulating drying oven for ABS plastic sheets. Utility Model Content

[0003] The main purpose of this invention is to provide an ABS plastic sheet hot air circulating drying oven, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An ABS plastic sheet hot air circulating drying oven includes a box body with support legs fixedly installed at the four corners of the lower end of the box body. A door is movably installed at the front end of the box body via a hinge, and a viewing window is provided at the front of the door. A placement mechanism is provided inside the box body. A connecting box is fixedly installed at the upper middle part of the left end of the box body. An output pipe is provided at the left end of the connecting box. An induced draft fan is fixedly installed at the right end of the output pipe. A first connecting pipe is fixedly installed at the right end of the induced draft fan. Five first through pipes are provided on the right side of the outer surface of the first connecting pipe. Several heating wires are provided inside the connecting box. A conveying pipe is provided at the upper right end of the connecting box. A second connecting pipe is provided at the upper right end of the box body. The conveying pipe is fixedly connected to the middle right side of the outer surface of the second connecting pipe. Five second through pipes are provided on the left side of the outer surface of the second connecting pipe.

[0006] Preferably, the right ends of the five first through-tubes all penetrate the lower left part of the box and extend to the inner left side of the box.

[0007] Preferably, the left portions of the five second through-tubes all penetrate the upper right end of the housing and extend to the inner right side of the housing.

[0008] Preferably, the connecting box, the output pipe, and the induced draft fan are all connected to the interior of the box body through the first connecting pipe, the conveying pipe, and the second connecting pipe.

[0009] Preferably, the placement mechanism includes a placement seat, with two forklift slots at the front center of the placement seat, an installation frame at the upper end of the placement seat, a plurality of partitions inside the installation frame, a plurality of ventilation holes on the outer surfaces of the partitions and the outer surface of the installation frame, and anti-tipping doors at the front and right ends of the installation frame via hinges, with handles at the front ends of the two anti-tipping doors.

[0010] Preferably, the left and right ends of the mounting frame do not contact the first through pipe and the second through pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By placing several ABS plastic sheets that need to be dried between the partitions inside the placement seat, and then closing the anti-tipping door, the forklift head is inserted into the two forklift slots to easily place the entire placement seat into the box for quick and easy installation. After drying for a certain period of time, the box door is opened, and the forklift head is inserted into the two forklift slots again to quickly remove the dried ABS plastic sheets and start the next round of drying, further improving drying efficiency and making it convenient to use.

[0013] 2. By closing the chamber door and turning on the exhaust fan via the controller, the exhaust fan blows air into the output pipe, which then delivers it to the connecting box. The incoming air is heated by several heating wires inside the connecting box, and then delivered to the second connecting pipe through the conveying pipe. Finally, it is delivered into the chamber through five second through-pipes, facilitating the drying of the ABS plastic sheets inside. Then, the cooled air is delivered back to the connecting box for heating through the five first through-pipes and the exhaust fan, thus achieving cyclic drying. Attached Figure Description
