[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2This utility model provides an embodiment of a paper feeding mechanism with anti-paper jam function, including a processing box 1. The processing box 1 provides a rigid support frame for the overall mechanism, forming a sealed working chamber for processing paperboard 4, and integrating the installation interfaces of various functional modules. A box door 2 is detachably connected to the front surface of the processing box 1. The box door 2 is used to control the opening and closing of the internal maintenance channel of the processing box 1, facilitating the replacement of the cleaning pad 95 and troubleshooting paper jams. A feed channel 3 is fixedly connected to the right surface of the processing box 1, defining the directional conveying path of the paperboard 4. Single-layer continuous feeding is achieved through the cooperation of the horizontal support surface and the side guide rail. The paperboard 4 is placed on the upper surface of the feed channel 3. The paperboard 4 serves as the material to be processed. After being input through the feed channel 3, it sequentially completes the drying, dust removal, and anti-paper jam treatment processes. The inner wall of the processing box 1... An electric heating plate 11 is fixedly installed on the lower surface. The electric heating plate 11 provides an auxiliary bottom heat source and eliminates condensation on the lower surface of the cardboard 4 through heat radiation. It forms a three-dimensional drying system with the hot air blower 5. Positioning rollers 10 are fixedly installed on both the left and right ends of the rear surface of the inner wall of the processing box 1 near the upper side of the electric heating plate 11. The positioning rollers 10 have a pair of limiting structures. The adjustable spacing design adapts to cardboard 4 of different widths and ensures the straightness of the feeding path. The hot air blower 5 is fixedly installed on the upper surface of the processing box 1. Multiple sets of mounting columns 6 are fixedly connected to the left surface of the processing box 1. The mounting columns 6 provide modular installation interfaces for external equipment to enhance the expansion compatibility of the mechanism. An auxiliary component 8 is set inside the processing box 1 near the lower side of the hot air blower 5. A cleaning component 9 is set on the left surface of the inner wall of the processing box 1.

[0025] Reference Figure 2 - Figure 4The cleaning component 9 includes a mounting plate 91, which is detachably connected to the left inner wall of the processing box 1 via fixing bolts 93. The mounting plate 91, through the fixing bolts 93, enables the detachable positioning of the cleaning module and provides a mounting reference surface for the elastic element 92. A shelf 94 is elastically connected to the axial center of the right surface of the mounting plate 91 via the elastic element 92. The shelf 94 serves as a support platform for the cleaning pad 95, and the elastic element 92 provides pressure buffering to prevent damage to the cardboard 4 caused by rigid contact. The left end of the elastic element 92 is fixedly connected to the right surface of the mounting plate 91, and the right end is fixedly installed on the left surface of the shelf 94. The elastic element 92 uses a compression spring structure to provide adaptive pressure to the shelf 94, ensuring dynamic contact between the cleaning pad 95 and the paper feed roller. Multiple sets of cleaning pads 95 are detachably connected to the right surface of the shelf 94. The cleaning pads 95 are made of replaceable non-woven fabric with a microporous surface structure that adsorbs dust from the cardboard 4. The friction between the main paper feed roller 98 and the paper feed roller 98 enables self-cleaning. A collection box 7 is detachably connected to the rear surface of the processing box 1 near the lower side of the cleaning pad 95. The collection box 7 is used to collect paper scraps scraped off by the cleaning pad 95, realizing centralized processing of processing debris. A rotating column 96 is rotatably connected to the rear surface of the inner wall of the processing box 1. The rotating column 96 serves as the rotation center of the paper feed roller system. It is installed in the processing box 1 through a bearing seat to achieve low-friction rotation. Paper feed auxiliary rollers 97 are fixedly installed at both ends of the outer wall of the rotating column 96. The paper feed auxiliary rollers 97 are symmetrically distributed at both ends of the rotating column 96. The surface rubber coating increases the coefficient of friction with the paperboard 4 and prevents lateral deviation. The main paper feed roller 98 is fixedly installed at the axis of the outer wall of the rotating column 96. The outer walls of the main paper feed roller 98 and the paper feed auxiliary rollers 97 are in contact with the outer surface of the cleaning pad 95. The main paper feed roller 98 is designed with a central high-friction zone, which dominates the feeding motion of the paperboard 4. At the same time, it achieves surface dust removal through contact with the cleaning pad 95.

[0026] Reference Figure 3 - Figure 5The auxiliary component 8 includes an auxiliary plate 81, which is fixedly installed inside the processing box 1 near the lower side of the hot air blower 5. The auxiliary plate 81 serves as the core airflow guiding structure for hot air flow field control, evenly distributing the airflow from the hot air blower 5 to the surface of the cardboard 4 via the air duct plate 86. Auxiliary slots 85 are provided at both ends of the upper surface of the auxiliary plate 81, providing a through-type installation channel for the rotating shaft 83. Two sets of motors 82 are fixedly installed on the rear surface of the processing box 1 near the rear side of the auxiliary plate 81. The motors 82 provide the rotational driving force for the baffle plate 84. The rotation is controlled by adjusting the rotation... The speed control of airflow disturbance intensity is achieved by connecting a rotating shaft 83 to the output shaft of motor 82. The rotating shaft 83 transmits the torque of motor 82 to the baffle 84. A dynamic sealing structure is adopted to prevent hot air leakage. The baffle 84 is fixedly installed on the outer wall of rotating shaft 83. The baffle 84 disrupts the laminar flow state of hot airflow through periodic rotation, preventing warping of cardboard 4 caused by local overheating. An air duct plate 86 is provided at the center of the upper surface of auxiliary plate 81. The air duct plate 86 is a honeycomb-shaped air guiding element that guides hot air vertically to the surface of cardboard 4, thereby optimizing drying efficiency and energy utilization.

[0027] Working principle:

[0028] The processing box 1, acting as a rigid support frame, is first closed by its removable front door 2, forming a sealed working chamber. The electric heating plate 11 is energized to preheat the bottom plate area to the set temperature via thermal radiation. Simultaneously, the hot air blower 5 starts, generating directional hot air. An external temperature and humidity sensor pre-installed on the mounting column 6 monitors the internal environment in real time, providing data for closed-loop control. The cardboard 4 is placed horizontally sheet by sheet on the support surface of the feed channel 3. The side guide rails of the feed channel 3 limit the lateral position of the cardboard 4, ensuring it enters the processing box 1 in a single-layer, zero-overlap state. When the front end of the cardboard 4 touches the positioning roller 10, the paired limiting structure automatically adjusts the roller spacing according to the width of the cardboard 4, so that the cardboard 4 continues to move forward in a straight line. The cardboard 4 enters the working area of ​​the auxiliary component 8. The auxiliary plate 81, as the core flow guiding structure of the hot air flow field, guides the high-speed airflow output by the hot air blower 5 into the air duct plate 86. The honeycomb air duct plate 86 blows the hot air vertically and evenly onto the upper surface of the cardboard 4 to achieve rapid surface drying. At the same time, the electric heating plate 11 continuously radiates heat to the lower surface of the cardboard 4 to eliminate condensation. The two form a three-dimensional drying system.

[0029] To prevent warping due to localized overheating, motor 82 drives shaft 83 to rotate, causing baffle 84 to perform periodic turbulence within auxiliary trough 85. This disrupts the laminar flow of hot air, ensuring a uniform temperature distribution. The dried cardboard 4 continues forward into cleaning assembly 9. Rotating column 96 is mounted on the rear surface of processing box 1 via bearing seats and rotates at a constant speed under the drive of an external servo system. The paper feed rollers 97 at both ends of the column clamp the cardboard 4 with high-friction rubber-coated surfaces to prevent lateral displacement. The central main paper feed roller 98 provides the main feed force, keeping the cardboard 4 in place. Moving forward at a constant speed, the mounting plate 91 is fixed to the left surface of the inner wall of the processing box 1 by the fixing bolts 93, providing a reference surface for the elastic element 92. The elastic element 92 (compression spring) pushes the placement plate 94 toward the paper feed roller system, so that the cleaning pad 95 adheres to the outer surface of the main paper feed roller 98 and the auxiliary paper feed roller 97 with adaptive pressure. The non-woven microporous structure of the cleaning pad 95 adsorbs the dust carried by the roller surface and the paperboard 4 in real time, and at the same time achieves self-cleaning by using relative friction with the roller surface. The scraped dust falls into the detachable collection box 7 under the action of gravity, achieving centralized treatment and avoiding secondary dust.

[0030] After drying and dust removal, the cardboard 4 is smoothly output to the downstream process under the joint drive of the main paper feed roller 98 and the auxiliary paper feed roller 97. Throughout the process, the positioning roller 10, auxiliary components 8, cleaning components 9 and collection box 7 work together to form an integrated closed loop of "drying-dust removal-anti-paper jamming", which significantly reduces the probability of paper jamming caused by humidity, dust or roller surface contamination. When it is necessary to replace the cleaning pad 95 or troubleshoot paper jamming, the box door 2 can be opened quickly; the fixing bolts 93 can be loosened to remove the mounting plate 91 and its auxiliary cleaning module. The interface reserved on the mounting column 6 can be expanded to add additional modules such as visual inspection and static elimination to meet the needs of different working conditions.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
