Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to a corrugated cardboard drying and leveling mechanism. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and the cardboard, and the structure of the carton itself. It is mainly made by pulping straw pulp and waste paper to make a base paperboard similar to yellow cardboard, which is then mechanically rolled into a corrugated shape, and finally bonded to the linerboard with adhesives such as sodium silicate.

[0003] After the corrugated cardboard is bonded, it needs to be dried. The corrugated cardboard is dried using a dryer, which allows the bonding of the corrugated cardboard to be completed quickly.

[0004] However, in the existing method, the corrugated cardboard is placed directly during the drying process, which makes the cardboard prone to deformation, thus affecting the quality of the product. Utility Model Content

[0005] The purpose of this invention is to provide a corrugated cardboard drying and leveling mechanism, which solves the problem that in the existing corrugated cardboard drying process, the cardboard is placed directly, which causes the cardboard to deform easily and thus affects the quality of the product.

[0006] To achieve the above objectives, this utility model employs a corrugated cardboard drying and leveling mechanism, comprising a box, a conveyor belt, and a leveling assembly. The box has two through holes, and the conveyor belt is disposed within the box.

[0007] The leveling assembly includes a drying module, a leveling plate, two sliding rods, a movable frame, a disc, a circular shaft, a support, and a drive rod. The drying module is mounted on the housing. Both sliding rods are slidably connected to the housing and movably pass through it. The leveling plate is fixedly connected to both sliding rods and is located within the housing. The movable frame is fixedly connected to both sliding rods and is located above the housing. The circular shaft is movably connected to the movable frame and is located within it. The support is fixedly connected to the housing and is located above it. The drive rod is rotatably connected to the support. The disc is fixedly connected to the drive rod and is also fixedly connected to the circular shaft, which is eccentrically positioned relative to the shaft.

[0008] The drying module includes a drying chamber, a mounting frame, an electric heating element, an air inlet pipe, and a fan. The drying chamber is fixedly connected to the housing and located above the housing. The two ends of the air inlet pipe are respectively connected to the drying chamber and the housing. The mounting frame is fixedly installed inside the drying chamber. The electric heating element is fixedly connected to the mounting frame and located inside the mounting frame. The fan is fixedly installed inside the housing.

[0009] The leveling component also includes a scale rod, which is fixedly connected to the movable frame and located below the movable frame. The scale rod is also movably connected to the box body and passes through the box body.

[0010] The leveling assembly also includes two traction springs, with each traction spring having its two ends fixedly connected to the housing and the movable frame, respectively.

[0011] The corrugated cardboard drying and leveling mechanism further includes two positioning arc blocks, both of which are fixedly connected to the box body and located on the outer side wall of the box body, with one of the through holes located between the two positioning arc blocks.

[0012] This utility model discloses a corrugated cardboard drying and leveling mechanism. During the drying and leveling of cardboard, the drying component heats the box, and the cardboard enters the box through the through-hole. The cardboard moves within the box via the conveyor belt, simultaneously driving the drive rod on the support to rotate. The drive rod drives the disc to rotate. Because the circular shaft and the disc are eccentrically positioned, the movable frame is pushed and pulled up and down by the circular shaft, realizing the lifting and lowering of the movable frame. Subsequently, the movable frame drives the leveling plate to lift and lower via the slide rod, positioning the leveling plate above the cardboard. The disc rotation stops, and the cardboard dries within the box. The dried cardboard is then conveyed outwards by the conveyor belt. This method achieves the leveling of corrugated cardboard, preventing deformation and improving product quality. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-5 This utility model provides a corrugated cardboard drying and leveling mechanism: including a box 101, a conveyor belt 102 and a leveling component, wherein the box 101 has two through holes 119 and the conveyor belt 102 is disposed inside the box 101;

[0022] The leveling assembly includes a drying module, a leveling plate 103, two sliding rods 104, a movable frame 105, a disc 106, a circular shaft 107, a bracket 108, and a drive rod 109. The drying module is mounted on the housing 101. Both sliding rods 104 are slidably connected to the housing 101 and movably pass through the housing 101. The leveling plate 103 is fixedly connected to both sliding rods 104 and is located within the housing 101. The movable frame 105 is connected to both sliding rods. 104 is fixedly connected and located above the housing 101. The circular shaft 107 is movably connected to the movable frame 105 and located inside the movable frame 105. The bracket 108 is fixedly connected to the housing 101 and located above the housing 101. The drive rod 109 is rotatably connected to the bracket 108. The disc 106 is fixedly connected to the drive rod 109. The disc 106 is also fixedly connected to the circular shaft 107 and is eccentrically positioned relative to the circular shaft 107.

[0023] In this embodiment, during the drying and leveling of the cardboard, the drying assembly heats the interior of the box 101. The cardboard enters the box 101 through the through hole 119 and moves within the box 101 via the conveyor belt 102. Simultaneously, the drive motor 111 on the support 108 is activated, driving the drive rod 109 on the support 108 to rotate. The drive rod 109 then rotates the disc 106. Since the circular shaft 107 and the disc 106 are eccentrically positioned... The movable frame 105 is pushed and pulled up and down by the circular shaft 107, realizing the lifting and lowering of the movable frame 105. Then, the movable frame 105 drives the flat plate 103 to lift and lower through the slide rod 104, so that the flat plate 103 is above the cardboard, and the rotation of the disc 106 stops. The cardboard will be dried in the box 101, and the dried cardboard will be transported out by the conveyor belt 102. By adopting the above method, the corrugated cardboard can be leveled, avoiding deformation of the cardboard and improving the quality of the product.

[0024] Furthermore, the drying module includes a drying chamber 110, a mounting frame 112, an electric heating element 113, an air inlet pipe 114, and a fan 115.

The electric heating element 113 is fixedly connected to the mounting frame 112 and is located inside the mounting frame 112. The fan 115 is fixedly installed inside the housing 101.

[0025] In this embodiment, when the temperature inside the chamber 101 is increased, the electric heating element 113 and the fan 115 inside the drying chamber 110 are activated. The electric heating element 113 heats the air inside the drying chamber 110, and the fan 115 introduces the hot air into the air inlet pipe 114. Subsequently, the hot air enters the chamber 101 through the air inlet pipe 114, and the temperature inside the drying chamber 110 rises, causing the cardboard to be heated and dried inside the drying chamber 110.

[0026] Furthermore, the leveling assembly also includes a scale rod 116, which is fixedly connected to the movable frame 105 and located below the movable frame 105. The scale rod 116 is also movably connected to the box body 101 and passes through the box body 101.

[0027] In this embodiment, by setting the scale rod 116, which has the same length as the slide rod 104, when paper of different thicknesses is placed in the box 101, the scale rod 116 can be used to conveniently control the pressing of the flat plate 103 on the paper.

[0028] Furthermore, the leveling assembly also includes two traction springs 117, with each traction spring 117 having its two ends fixedly connected to the housing 101 and the movable frame 105, respectively.

[0029] In this embodiment, by providing the traction spring 117, the movable frame 105 can be supported and pulled, thereby increasing the stability of the flat plate 103.

[0030] Furthermore, the corrugated cardboard drying and leveling mechanism also includes two positioning arc blocks 118, both of which are fixedly connected to the box body 101 and located on the outer side wall of the box body 101, with one of the through holes 119 located between the two positioning arc blocks 118.

[0031] In this embodiment, by providing the positioning arc block 118 outside the through hole 119 of the box body 101, the positioning arc block 118 guides the cardboard into the through hole 119, making it convenient for the cardboard to enter the box body 101 and simplifying the operation.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
