In the automated process of paper stick production, the cutting process is a key step in processing continuously formed paper stick raw materials into specifications and dimensions. Its cutting accuracy, efficiency, and stability directly affect the quality of paper stick products and production capacity.

[0003] Currently, traditional paper stick cutting devices generally suffer from technical defects such as poor feeding stability, insufficient cutting accuracy, low production efficiency, and poor versatility and adjustability. They are unable to meet the high precision, high efficiency, and multi-specification adaptability requirements of products such as cotton swabs for paper stick cutting. Developing a paper stick cutting device that can achieve stable single-stick feeding, precise synchronous cutting, and efficient automated production has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a paper stick cutting device.

[0005] The present invention adopts the following technical solution:

[0006] A paper rod cutting device includes a stacking mechanism, a conveying mechanism, and a cutting mechanism arranged sequentially along the paper rod processing direction. The stacking mechanism includes a paper rod trough for stacking paper rods to be processed. The conveying mechanism includes a paper rod conveying roller assembly, a pressure roller, and a guide plate. One end of the paper rod conveying roller assembly is connected to the paper rod trough, and the other end is connected to the guide plate. The pressure roller is positioned above the guide plate, and a feeding gap is formed between the pressure roller and the guide plate to allow a single paper rod to pass through. The paper rod conveying roller assembly conveys the paper rods from the paper rod trough to the guide plate. The pressure roller cooperates with the guide plate to drive the paper rods to be conveyed along the feeding gap. The cutting mechanism includes a conveyor line and a cutting tool fixed above the conveyor line, with the cutting end of the cutting tool extending to the discharge side of the guide plate.

[0007] Preferably, the end of the paper rod feed trough away from the paper rod conveying roller assembly is provided with a guide ramp.

[0008] Preferably, the paper rod conveying roller assembly includes a main conveying roller, a transition conveying roller, and a drive module connected to the main conveying roller and the transition conveying roller; the paper rod trough has a discharge notch at one end facing the paper rod conveying roller assembly, and the main conveying roller is partially placed in the discharge notch; the transition conveying roller is located between the main conveying roller and the guide base plate.

[0009] Preferably, the outer wall of the main conveying roller is provided with a plurality of receiving grooves extending along its own axial direction, the receiving grooves being used to receive paper rods.

[0010] Preferably, the transition conveyor roller includes a rolling element and two conveyor plates. The two conveyor plates are respectively installed on both axial sides of the rolling element. The outer edge of the conveyor plate is provided with connected toothed grooves. The toothed grooves of the two conveyor plates are respectively used to clamp the two ends of the paper rod.

[0011] Preferably, the toothed groove is inclined along the rotation direction of the transition conveyor roller.

[0012] Preferably, portions of the two conveying plates are located on opposite sides of the axial direction of the main conveying roller, and the distance between the two conveying plates is greater than the axial length of the main conveying roller.

[0013] Preferably, the top of the conveyor plate is provided with an anti-detachment plate, and the bottom of the anti-detachment plate is provided with an arc-shaped abutment surface.

[0014] Preferably, the guide plate includes a vertical feeding section, an arc-shaped transition section, and a horizontal discharging section that are sequentially arranged and integrally formed along the paper rod conveying direction; the vertical feeding section has an avoidance notch, and the conveying plate can rotatably pass through the avoidance notch in part.

[0015] Preferably, the outer wall of the pressure roller is fitted with a rubber sleeve to increase friction.

[0016] The beneficial effects of this invention are as follows: The paper stick cutting device of this invention, by sequentially arranging a stacking mechanism, a conveying mechanism, and a cutting mechanism along the paper stick processing direction, realizes automated continuous processing of paper sticks from stacking to cutting, effectively solving the technical defects of traditional paper stick cutting devices such as poor feeding stability, insufficient cutting accuracy, low production efficiency, and poor versatility and adjustability. The stacking mechanism's paper stick trough, combined with a guide ramp and a discharge notch, achieves orderly feeding of paper sticks. In the conveying mechanism, the main conveying roller of the paper stick conveying roller assembly is equipped with a receiving groove, and the conveying plates of the transition conveying roller are equipped with toothed grooves inclined along the rotation direction. The two conveying plates are partially distributed on both sides of the main conveying roller's axial direction, with a spacing greater than the axial length of the main conveying roller. Combined with anti-detachment plates with arc-shaped contact surfaces on the top of the conveying plates, this achieves both smooth transition and anti-detachment of the paper sticks between the rollers, and prevents jamming and falling during paper stick conveying. The guide base plate is integrally formed vertical... The system features a straight feed section, an arc-shaped transition section, and a horizontal discharge section, with clearance gaps allowing the conveyor plate to partially rotate and pass through. These gaps, in conjunction with pressure rollers fitted with rubber sleeves on the outer wall, create a feeding gap for individual paper rods. This design accommodates changes in the paper rod's conveying posture and increases friction to ensure uniform, slip-free single-rod conveying, preventing paper rod stacking and misalignment. The cutting mechanism's cutting blades are precisely positioned at the junction of the guide plate's discharge side and the conveyor line, achieving precise, fixed-length cutting of the paper rods and effectively solving problems of uneven cuts and large length errors. The integrated layout and strong coordination of all mechanisms create a seamless automated processing flow, significantly shortening the processing cycle of a single paper rod, improving production efficiency, and adapting to high-speed automated production cycles. Furthermore, the structural design of each component avoids motion interference issues, and the flexible structure reduces equipment wear and extends service life. The adjustable feeding gap accommodates paper rods of different diameters, enhancing the device's versatility, operational reliability, and adaptability. It also effectively protects the paper rod surface, ensuring the quality of the finished product. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] like Figures 1 to 6 As shown, the paper stick cutting device disclosed in this invention has a stacking mechanism 10, a conveying mechanism 20 and a cutting mechanism 30 arranged sequentially along the paper stick processing direction. The three work together to realize the automated continuous processing of paper sticks from stacking and conveying to cutting, which is suitable for the precise cutting of paper sticks for cotton swab production.

[0023] Specifically, the stacking mechanism 10 includes a paper rod trough 11, which has an open structure for batch stacking paper rod raw materials to be processed. A guide ramp 12 is provided at the end of the paper rod trough 11 away from the conveying mechanism 20. The guide ramp 12 slopes downwards towards the conveying mechanism 20 to connect to the previous processing station and guides the paper rods towards the discharge end of the trough using gravity, preventing the paper rods from accumulating and remaining in the trough. A discharge notch 13 is provided at the end of the paper rod trough 11 facing the conveying mechanism 20, providing a channel for the paper rods to be conveyed from the trough to the conveying mechanism 20.

[0024] Specifically, the conveying mechanism 20 includes a paper rod conveying roller assembly 21, a pressure roller 26, and a guide base plate 25.

[0025] The paper rod conveying roller assembly 21 includes a main conveying roller 22, a transition conveying roller 23, and a drive module 24. The drive module 24 uses a servo motor, which is connected to the main conveying roller 22 and the transition conveying roller 23 respectively, and can drive them to rotate synchronously to ensure consistent conveying rhythm. The main conveying roller 22 is partially placed in the discharge notch 13 of the paper rod trough 11. Its outer wall is provided with multiple receiving grooves 221 extending along its own axial direction. The spacing and width of the receiving grooves 221 are adapted to the diameter of the paper rod to be processed, so that a single paper rod can be accommodated at a time and driven to rotate and convey it, avoiding the simultaneous feeding of multiple paper rods. The transition conveyor roller 23 is located between the main conveyor roller 22 and the guide base plate 25. It includes a rolling element 231 and two conveyor plates 232. The rolling element 231 is connected to the drive module 24. The two conveyor plates 232 are fixedly installed on both sides of the rolling element 231, and parts of the two conveyor plates 232 are located on both sides of the main conveyor roller 22. The distance between them is greater than the axial length of the main conveyor roller 22, ensuring that the paper rod can smoothly transition from the main conveyor roller 22 to the transition conveyor roller 23. The outer edge of the conveyor plate 232 is provided with continuously distributed toothed grooves 233. The toothed grooves 233 are inclined along the rotation direction of the transition conveyor roller 23. The toothed grooves 233 of the two conveyor plates 232 are aligned and together form an area for clamping the two ends of the paper rod. The inclined structure can actively receive the paper rod sent out by the receiving groove 221 of the main conveyor roller 22, preventing the paper rod from falling off or getting stuck. Each conveyor plate 232 is provided with an anti-detachment plate 234 at the top and an arc-shaped abutment surface at the bottom. The arc-shaped abutment surface can limit the paper rod from above to prevent the paper rod from coming out of the toothed groove 233 due to vibration during the conveying process, and also avoid scratching the surface of the paper rod.

[0026] The guide base plate 25 is a one-piece molded structure, with a vertical feeding section 251, an arc-shaped transition section 252, and a horizontal discharge section 253 arranged sequentially along the paper rod conveying direction. The overall structure adapts to the posture change of the paper rod from vertical to horizontal conveying, ensuring a smooth conveying trajectory. The vertical feeding section 251 has an avoidance notch 254, the position of which corresponds to the conveying plate 232 of the transition conveying roller 23. A portion of the conveying plate 232 rotatably passes through the avoidance notch 254, providing space for the rotation of the conveying plate 232, while allowing the toothed groove 233 to accurately feed the paper rod into the feeding gap of the guide base plate 25.

[0027] The pressure roller 26 is located above the guide base plate 25, and its outer wall is fitted with a rubber sleeve 261 to increase friction. A feeding gap is formed between the pressure roller 26 and the guide base plate 25 to allow a single paper rod to pass through. The gap width can be flexibly adjusted according to the diameter of the paper rod. The pressure roller 26 rotates under the drive of the drive assembly, and cooperates with the guide base plate 25 to form a clamping driving force, driving the paper rod to be conveyed at a uniform speed along the feeding gap.

[0028] Specifically, the cutting mechanism 30 includes a conveyor line 31 and a cutting blade 32. The cutting blade 32 is a fixed blade, fixed above the conveyor line 31, with its cutting end extending to the horizontal discharge side of the guide plate 25, precisely corresponding to the end position of the paper stick conveyor. The cutting process relies on the coordinated action of multiple forces: the rubber sleeve 261 on the outer wall of the pressure roller 26 increases friction, driving the paper stick to move at a constant speed towards the fixed blade; the paper sticks stacked in the paper stick trough 11 form a natural thrust, assisting in pushing the front paper stick towards the cutting end; after the paper stick moves to the conveyor line 31, the conveyor line 31 provides continuous driving force, driving the paper stick to move continuously towards the blade. Through the superposition of the above three forces, the paper stick makes precise contact with the fixed blade and completes the cutting, ensuring a smooth cut and consistent cutting length. The conveyor line 31 is a belt conveyor line 31, used to receive the paper sticks from the conveyor mechanism 20, and after cutting, transports the finished paper sticks to the subsequent processing station.

[0029] The working principle of the paper stick cutting device involved in this invention is as follows: First, the paper sticks to be processed are placed in batches into the paper stick trough 11. The paper sticks move towards the discharge notch 13 under the action of the guide ramp 12. The drive module 24 is started, driving the main conveying roller 22 and the transition conveying roller 23 to rotate synchronously. The main conveying roller 22 carries the paper sticks in the trough out one by one through the receiving groove 221 and sends them into the toothed groove 233 of the transition conveying roller 23. The anti-detachment plate 234 on the top of the conveying plate 232 upper limit the paper sticks. The transition conveying roller 232... The feeding roller 23 smoothly conveys the paper rod to the vertical feeding section 251 of the guide base plate 25 through the inclined toothed groove 233. The conveying plate 232 passes through the avoidance gap 254 to complete the paper rod handover. The paper rod moves along the three-section structure of the guide base plate 25. The pressure roller 26 cooperates with the guide base plate 25 to drive the paper rod to the cutting position at a uniform speed along the feeding gap. The cutting blade 32 cuts the paper rod. The cut paper rod product falls onto the conveyor line 31 and is conveyed to the next process by the conveyor line 31 to complete the single cutting process.

[0030] Compared with the prior art, the paper stick cutting device involved in this invention, by sequentially arranging a stacking mechanism 10, a conveying mechanism 20 and a cutting mechanism 30 along the paper stick processing direction, realizes the automated continuous processing of paper sticks from stacking to cutting, effectively solving the technical defects of traditional paper stick cutting devices such as poor feeding stability, insufficient cutting accuracy, low production efficiency and poor versatility and adjustability. The paper rod feed trough 11 of the stacking mechanism 10 is equipped with a guide ramp 12 and a discharge notch 13 to achieve orderly feeding of paper rods. In the conveying mechanism 20, the main conveying roller 22 of the paper rod conveying roller assembly 21 is provided with a receiving groove 221, and the conveying plate 232 of the transition conveying roller 23 is provided with a toothed groove 233 inclined in the direction of rotation. The two conveying plates 232 are partially distributed on both sides of the axial direction of the main conveying roller 22, and the distance between them is greater than the axial length of the main conveying roller 22. With the anti-detachment plate 234 with an arc-shaped abutment surface on the top of the conveying plate 232, it can not only achieve a smooth transition and limit and prevent detachment of paper rods between rollers, but also avoid jamming and falling of paper rods during conveying. The guide base plate 25 The vertical feeding section 251, the arc-shaped transition section 252, and the horizontal discharge section 253 are integrally formed. An avoidance gap 254 is provided to allow the conveyor plate 232 to rotate and pass through partially. It cooperates with the pressure roller 26 with the rubber sleeve 261 on the outer wall to form a feeding gap for a single paper rod to pass through. This not only adapts to the posture changes of the paper rod conveying, but also increases the friction to achieve uniform speed and slip-free single-rod conveying of the paper rod, thus avoiding paper rod stacking and misalignment from the root. The cutting blade 32 of the cutting mechanism 30 is precisely set at the junction of the discharge side of the guide base plate 25 and the conveyor line 31 to achieve precise fixed-length cutting of the paper rod, effectively solving the problems of uneven cut and large length error. The integrated layout of each mechanism and its strong coordination of actions form a seamless automated processing flow, which significantly shortens the processing cycle of a single paper stick, improves production efficiency, and is compatible with high-speed automated production rhythm. At the same time, the structural design of each component avoids motion interference problems, the flexible structure design reduces equipment wear and extends service life, and the feeding gap can be flexibly adjusted to adapt to the processing of paper sticks of different diameters. This improves the versatility, operational reliability and adaptability of the device, and can also effectively protect the surface of the paper sticks and ensure the quality of the finished paper sticks.

[0031] The above description merely illustrates preferred technical solutions of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
