Description

Technical Field

[0001] This utility model relates to the field of paper product manufacturing technology, and in particular to a paper product feeding mechanism. Background Technology

[0002] Paper products refer to various products made primarily from paper or paperboard. They are widely used in daily life, industrial production, culture and education, and many other fields. In the paper product manufacturing process, the paper feeding mechanism is a crucial component, and its performance directly affects the production efficiency and quality of paper products.

[0003] Existing conveyor systems used in paper product manufacturing require manual operation of handles to raise and lower the limit mechanisms, which consumes manpower and results in low production efficiency.

[0004] The existing patent (publication number: CN218144916U) relates to the field of paper product production and transportation technology, specifically to a paper product feeding mechanism, including a limiting frame and a cover plate, and a transmission assembly. The transmission assembly includes a power component, a lifting screw, a lifting slider, a connecting plate, and a limiting plate. First, the limiting plate is positioned above the limiting frame. Paper is gradually stacked on the limiting plate. Simultaneously, the power component drives the lifting screw to reverse, causing the lifting slider to gradually move downwards. Consequently, the connecting plate and the limiting plate gradually move downwards, carrying the placed paper into the limiting frame. After being stored in the limiting frame, the cover plate is closed. The weight of the cover plate prevents the paper from falling. The paper is transported by moving the limiting frame, and the lifting of the limiting plate is adjusted electrically during paper placement, reducing manual labor and effectively improving production efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing paper feeding mechanisms typically clamp the paper using two conveyor rollers, which then rotate relative to each other to transport the paper. These existing paper feeding structures are generally not convenient for adjusting the conveying pressure based on the paper thickness, nor are they convenient for adjusting the paper feeding angle, making it difficult to adapt to the needs of different production and processing applications.

[0006] Therefore, a paper feeding mechanism for paper product production is proposed. Utility Model Content

[0028] A paper feeding mechanism for paper product production includes a base plate 1, a paper feeding assembly 2 is provided on the top of the base plate 1, and an adjustment assembly 3 is provided on the bottom of the paper feeding assembly 2.

[0029] The paper feeding assembly 2 includes a paper guide frame 201. The bottom of the inner cavity of the paper guide frame 201 is rotatably connected to an active conveyor roller 202 via a bearing. A conveyor motor 203 is fixedly connected to the bottom right side of the paper guide frame 201. The output shaft of the conveyor motor 203 is fixedly connected to the right end of the active conveyor roller 202. An electric lifting rod 204 is fixedly connected to the top of the paper guide frame 201. The output rod of the electric lifting rod 204 passes through the inner cavity of the paper guide frame 201 and is fixedly connected to a fixing plate 205. Multiple springs 206 are fixedly connected to the bottom of the fixing plate 205. A fixing frame 207 is fixedly connected to the bottom of the multiple springs 206. A driven conveyor roller 208 is rotatably connected to the inner cavity of the fixing frame 207 via a bearing.

[0030] In this embodiment: by setting up a base plate 1, a paper feeding assembly 2, and an adjustment assembly 3, the base plate 1 provides a supporting foundation for the paper feeding assembly 2 and the adjustment assembly 3 during use. The paper feeding assembly 2 enables stable paper feeding during the paper product manufacturing process and allows for easy adjustment of the feeding pressure according to the paper thickness, providing convenience for operators. The adjustment assembly 3 allows for adjustment of the paper feeding angle of the paper feeding assembly 2, thereby adapting to different production and processing needs and improving the flexibility of use.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the adjustment assembly 3 includes a first upright plate 301 and a second upright plate 302. The first upright plate 301 and the second upright plate 302 are respectively fixedly connected to the front and rear sides of the top of the base plate 1. The inner walls of the first upright plate 301 and the second upright plate 302 are rotatably connected to an adjustment rod 303 via bearings. A connecting block 304 is fixedly connected to the surface of the adjustment rod 303. The top of the connecting block 304 is fixedly connected to the bottom of the loop frame 201.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a positioning gear 305 is fixedly connected to the front end of the adjusting rod 303, and a lifting air rod 306 is provided at the bottom of the positioning gear 305. A locking tooth block 307 that works with the positioning gear 305 is fixedly connected to the output end of the lifting air rod 306. The top of the locking tooth block 307 is meshed with the bottom of the positioning gear 305.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a fixed bracket 308 is fixedly connected to the bottom of the lifting air rod 306, and the side of the fixed bracket 308 near the first upright plate 301 is fixedly connected to the first upright plate 301.

[0034] In this embodiment: by setting a first upright plate 301, a second upright plate 302, an adjusting rod 303, a connecting block 304, a positioning gear 305, a lifting air spring 306, a locking tooth block 307, and a fixing bracket 308, in use, the first upright plate 301 and the second upright plate 302 can support and fix the adjusting rod 303. When adjusting the paper feeding angle of the paper feeding assembly 2, the lifting air spring 306 can be activated, causing the output rod of the lifting air spring 306 to retract and drive the locking tooth block 307 to move downward, so that the locking tooth block 307 separates from the positioning gear 305, thereby releasing the lock on the positioning gear 305 and the adjusting rod 303. Then, by rotating the adjusting rod 303, the adjusting rod 304 can be adjusted to the first upright plate 301, the second upright plate 302, the adjusting rod 303 can be adjusted to the first upright plate 304, the second upright plate 302, the third upright plate 303, the fourth upright plate 304, the fifth upright plate 305, the sixth upright plate 306, the seventh upright plate 307, and the eighth upright plate 308. The vertical plate 301 and the second vertical plate 302 rotate through bearings, which in turn drives the connecting block 304 to rotate. The connecting block 304 drives the fixed frame 207 to rotate, thereby adjusting the paper feeding angle of the paper feeding assembly 2. After adjustment, the lifting air rod 306 can be activated, causing the output rod of the lifting air rod 306 to extend and drive the locking tooth block 307 to move upward, so that the locking tooth block 307 meshes with the positioning gear 305, thereby locking the positioning gear 305 and the adjusting rod 303. This completes the paper feeding angle adjustment of the paper feeding assembly 2, allowing the paper feeding assembly 2 to adapt to different production and processing needs and improving its flexibility. The lifting air rod 306 can be supported and fixed by the fixed bracket 308.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a first limiting rod 4 is fixedly connected to both sides of the top of the fixed plate 205. The top of the first limiting rod 4 extends through to the top of the spiral frame 201. A first sliding hole 5 is provided on both sides of the top of the spiral frame 201 to cooperate with the first limiting rod 4. The surface of the first limiting rod 4 is slidably connected to the inner wall of the first sliding hole 5.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, the inner cavity of the spring 206 is provided with a second limiting rod 6. The bottom of the second limiting rod 6 is fixedly connected to the top of the fixing frame 207. The top of the second limiting rod 6 extends through to the top of the fixing plate 205. The top of the fixing plate 205 is provided with a second sliding hole 7 that cooperates with the second limiting rod 6. The surface of the second limiting rod 6 is slidably connected to the inner wall of the second sliding hole 7.

[0037] In this embodiment: by setting the first limiting rod 4, the fixing plate 205 can be guided and limited to prevent it from shaking. By setting the first sliding hole 5, the first limiting rod 4 can pass through the U-shaped frame 201 and slide up and down. By setting the second limiting rod 6, the fixing frame 207 can be guided and limited to prevent it from shaking. By setting the second sliding hole 7, the second limiting rod 6 can pass through the fixing plate 205 and slide up and down.

[0038] Specifically, such as Figure 5 As shown, the top of the boom 201 has a through hole 8 for use with the electric lifting rod 204, and the output rod surface of the electric lifting rod 204 is slidably connected to the inner wall of the through hole 8.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, mounting blocks 9 are fixedly connected to the front and rear sides of both sides of the base plate 1, and mounting holes 10 are provided on the top of the mounting blocks 9.

[0040] In this embodiment: by providing through hole 8, the output rod of electric lifting rod 204 can pass through the loop frame 201 for telescopic output; by providing mounting block 9 and mounting hole 10, the base plate 1 can be installed and fixed with other equipment or support structure using bolts.

[0041] Working principle: In use, the paper to be conveyed passes between the active conveyor roller 202 and the driven conveyor roller 208. Then, the electric lifting rod 204 is activated, causing its output rod to push the fixed plate 205 downward. The fixed plate 205, through the spring 206, drives the fixed frame 207 downward, which in turn drives the driven conveyor roller 208 downward. This allows the driven conveyor roller 208 to work in conjunction with the active conveyor roller 202 to clamp the paper. As the fixed plate 205 continues to move downward, the spring 206 is gradually compressed, and the driven conveyor roller... As the pressure on the paper gradually increases with the roller 208, the electric lifting rod 204 and spring 206 work together to easily adjust the conveying pressure according to the paper thickness. The spring 206 assembly provides elastic cushioning; when the paper thickness fluctuates, the springs 206 automatically compress or extend to ensure a constant clamping force on the paper by the driven conveying roller 208. Then, by starting the conveying motor 203, its output shaft drives the active conveying roller 202 to rotate. The rotation of the active conveying roller 202 utilizes the clamping friction force... The driven conveyor roller 208 rotates in the opposite direction, thus ensuring stable paper feeding. When adjusting the paper feeding angle of the paper feeding assembly 2, the lifting air spring 306 can be activated, causing the output rod of the lifting air spring 306 to retract and drive the locking tooth block 307 downward, separating the locking tooth block 307 from the positioning gear 305. This releases the lock on the positioning gear 305 and the adjusting rod 303. Then, by rotating the adjusting rod 303, it rotates within the first vertical plate 301 and the second vertical plate 302 via bearings, driving the connecting... When the connecting block 304 rotates, it drives the fixed frame 207 to rotate, thereby adjusting the paper feeding angle of the paper feeding assembly 2. After adjustment, the lifting air rod 306 can be activated, causing the output rod of the lifting air rod 306 to extend and drive the locking tooth block 307 to move upward, so that the locking tooth block 307 meshes with the positioning gear 305, thereby locking the positioning gear 305 and the adjusting rod 303. This completes the adjustment of the paper feeding angle of the paper feeding assembly 2, allowing the paper feeding assembly 2 to adapt to different production and processing needs and improving its flexibility of use.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
