Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a corrugated cardboard drying device for clean production. Background Technology
[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard (also called boxboard) bonded together. It has good elasticity and extensibility. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. It is primarily made from traditional methods of pulping straw pulp and waste paper to create a base paperboard similar to cardboard, which is then mechanically rolled into a corrugated shape. Finally, it is bonded to the linerboard using adhesives such as sodium silicate. Chinese patent discloses a drying device for a corrugated cardboard production line (authorization announcement number CN216011603U). This patent technology relates to a drying device for a corrugated cardboard production line, including a support frame. A conveyor table is installed on the top of the support frame, and a drying chamber with a box structure is installed above the conveyor table. A set of conveyor rollers is arranged inside the conveyor table along the conveying direction of the corrugated cardboard. Hot air devices are symmetrically installed at both ends of the inner wall of the drying chamber, and several heat exchange holes are spaced apart on the hot air devices. A heating device is installed on the conveying path inside the drying chamber. The heating device is used to assist the drying of the corrugated cardboard in the drying chamber when the production progress of the corrugated cardboard increases. The corrugated cardboard conveyed on the conveyor rollers is pulled through the gap between two heating plates and dried when it comes into contact with the corrugated cardboard in the clamping gap. The drying is carried out in sections at the front, middle and rear of the conveying path, and the drying of the corrugated cardboard is carried out in conjunction with the hot air device, which solves the problem of high moisture content of the dried corrugated cardboard due to the increase in conveying speed. This patented technology solves the problem that when corrugated cardboard is dried in a continuous process in the drying chamber, the time the corrugated cardboard spends in the drying chamber decreases when the conveyor speed changes. Simply changing the temperature in the drying chamber is not enough to meet the drying requirements, which can easily lead to the moisture content of the dried corrugated cardboard exceeding the process requirements and affecting the product yield.
[0003] However, in the existing technology, the corrugated cardboard is prone to instability in the center of gravity during the drying process due to different specifications, which can cause the cleaned corrugated cardboard to fall out of the positioning position and deform after drying. It is necessary to solve the problem of adjusting the spacing of the corrugated cardboard during positioning and conveying to increase its applicability.
[0004] Therefore, those skilled in the art have provided a corrugated cardboard drying apparatus for clean production to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical effects and advantages of this utility model are as follows:
[0017] 1. Corrugated cardboard can smoothly enter the drying chamber through the corrugated cardboard conveyor mechanism. The hot air generated by the hot air blower forms a circular flow inside the drying chamber through the annular hot air duct, ensuring that the corrugated cardboard is heated evenly, thereby improving the drying efficiency.
[0018] 2. The distance between the two conveying structures can be adjusted according to the specifications of the corrugated cardboard. A servo motor drives a two-way lead screw, which causes the screw plate to move the conveying structure on the support crossbeam. This design allows the system to adapt to different specifications of corrugated cardboard, improving the system's applicability and flexibility. Attached Figure Description

[0031] For examples, please refer to Figures 1-5 This embodiment provides a corrugated cardboard drying device for clean production, including: a processing base 1; a corrugated cardboard conveying mechanism 2 for drying and moving corrugated cardboard is installed on the processing base 1; and a corrugated cardboard drying structure 3 for drying the corrugated cardboard conveyed on the corrugated cardboard conveying mechanism 2 is also installed on the processing base 1.
[0032] The corrugated cardboard conveying mechanism 2 includes a support vertical frame 201 integrally fixed on the processing base 1, and a support horizontal frame 202 fixed at the top of the support vertical frame 201. A bidirectional lead screw 203 is rotatably installed on the inner side of the support horizontal frame 202. Both ends of the bidirectional lead screw 203 are provided with screw transfer plates 205 for helical transmission. One end of the bidirectional lead screw 203 is connected to a servo motor 204 that provides power transmission. The corrugated cardboard conveying mechanism 2 includes a conveying structure 21 installed on the screw transfer plate 205. The conveying structure 21 includes a movable horizontal frame 2101 fixedly installed on the outer wall of the screw transfer plate 205.
[0033] The inner sides of both ends of the movable cross frame 2101 are rotatably mounted with transmission rollers 2102. One end of each transmission roller 2102 rotatably passes through the movable cross frame 2101 and is connected to a servo motor 2104. A conveyor belt 2103 for conveying and moving corrugated cardboard is wound between the two transmission rollers 2102.
[0034] The corrugated paper drying structure 3 includes a drying box 301 sleeved outside the conveying structure 21, the drying box 301 being cylindrical; the outer wall of the drying box 301 is provided with four hot air ducts 304 arranged in a ring, and a hot air fan 305 is installed inside the hot air ducts 304; a limiting bottom plate 302 is fixed to the bottom of the inner edge of the drying box 301, and a limiting top plate 303 is fixed to the top of the inner edge of the drying box 301.
[0035] The movable crossbeam 2101 is rotatably mounted with a ball bearing 2105 at a position corresponding to the limiting base plate 302, and the limiting base plate 302 is provided with a ball bearing groove 306 at a position corresponding to the ball bearing 2105; the movable crossbeam 2101 is slidably limited to the inside of the ball bearing groove 306 by the ball bearing 2105; a controller 4 is installed on the outer wall of the supporting vertical frame 201.
[0036] According to the above embodiments, the working principle of this invention is as follows:
[0037] When the corrugated cardboard is being cleaned and dried, it is moved to the conveying structure 21 of the corrugated cardboard conveying mechanism 2 via an external conveying connection device. The corrugated cardboard is then moved to the inside of the drying box 301 of the corrugated paper drying structure 3 via the conveying structure 21. It is then dried by hot air from the hot air blower 305 and discharged through the conveying structure 21 after completion.
[0038] The spacing between the two conveying structures 21 is adjusted according to the specifications of the corrugated cardboard. After the servo motor 204 is started, the servo motor 204 drives the bidirectional lead screw 203 to rotate. The rotating bidirectional lead screw 203 drives the screw transfer plate 205 to move along the support crossbeam 202, thereby adjusting the spacing between the conveying structures 21.
[0039] When the servo motor 2104 of the conveyor structure 21 is started, it can drive the transmission roller 2102 to rotate. The rotating transmission roller 2102 moves the transmission belt 2103, so that the transmission belt 2103 moves the corrugated cardboard.
[0040] Since the hot air ducts 304 are installed in a ring array on the drying box 301, when the hot air blower 305 is working, the hot air can circulate in a ring along the inner wall of the drying box 301, thereby increasing the drying efficiency of the corrugated cardboard.
[0041] After the hot air blower 305 is started, the hot air enters the drying chamber 301 through the hot air duct 304, and forms a uniform airflow in the annular air duct formed by the limiting bottom plate 302 and the limiting top plate 303, which dries the corrugated cardboard on the conveyor belt 2103 on both sides.
