[0001] The utility model relates to paper feeding device of auxiliary compression wheel arrangement. BACKGROUND

[0002] In the equipment such as leather machine, paperboard is used for processing into common structure, for example, in leather machine, paper feeding device is arranged to cooperate with paperboard conveying for edge covering, and the paper feeding device includes paper feeding belt, and in addition, the paper feeding belt needs to be equipped with compression wheel on the upper surface for holding paperboard to assist conveying, and a plurality of compression wheels are arranged to hold paperboard conveying more stably, and because the paperboard has certain thickness, the compression wheel needs to be equipped with spring floating, if each compression wheel in a plurality of compression wheels is separately equipped with spring floating operation, the structure is complex, assembly is troublesome and difficult, and the consistency of compression wheel cannot be ensured, which can easily lead to paper feeding deviation, if the compression wheels in a row are equipped with spring synchronous floating by being arranged on the vertically lifting frame, the paperboard cannot be smoothly conveyed, when the head of paperboard enters the lower part of compression wheel, the whole row of compression wheels is lifted at the same time, and the pressing effect is poor (influencing conveying), in addition, if the previous paperboard is still held and cooperated with conveying by the front compression wheels in the whole row, the front and rear compression wheels cannot be considered for pressing and conveying, and even the whole frame is not balanced and is stuck, and the operation is not smooth. SUMMARY

[0003] In view of the technical problems in the background art, the utility model aims at providing paper feeding device of auxiliary compression wheel arrangement for stably conveying paperboard.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: paper feeding device of auxiliary compression wheel arrangement, including support frame, paper feeding belt and compression wheel, the compression wheel is arranged above the paper feeding belt, and the utility model is characterized in that: the compression wheel is arranged on the movable pressure frame in sequence in the longitudinal direction, the first swing arm and the second swing arm are arranged on the support frame, one end of the first swing arm is hinged to the support frame, the other end of the first swing arm is hinged to the movable pressure frame, one end of the second swing arm is hinged to the support frame, the other end of the second swing arm is hinged to the movable pressure frame, and the spring component for pressing the movable pressure frame downward is arranged between the movable pressure frame and the support frame.

[0005] The above technical scheme can be variously optimized or supplemented as follows.

[0006] For example, the front end of the first swing arm is hinged to the support frame, the rear end of the first swing arm is hinged to the movable pressure frame, the front end of the second swing arm is hinged to the support frame, and the rear end of the second swing arm is hinged to the movable pressure frame.

[0007] For example, the first swing arm and the second swing arm are horizontally arranged between the support frame and the movable pressure frame.

[0008] For example, the movable pressure frame includes a longitudinal plate section and a vertical plate section. The longitudinal plate section is connected to the vertical plate section and is located at the lower part of the vertical plate section. The vertical plate section is arranged front and rear. The first swing arm and the second swing arm are respectively hinged to the corresponding vertical plate section. The movable pressure frame is respectively hinged to the first swing arm and the second swing arm through the corresponding vertical plate section.

[0009] The spring components are arranged front and rear, with a first spring connection part on the support frame and a second spring connection part on the movable pressure frame. The spring components are positioned between the first spring connection part and the second spring connection part.

[0010] For example, a first spring seat is provided at the first spring connection part, a second spring seat is provided at the second spring connection part, and a spring support rod is also provided on the second spring seat. The spring component is sleeved on the spring support rod. The first spring seat is provided with a through hole for the spring support rod to pass through, and there is a fitting clearance between the through hole and the spring support rod to allow the spring support rod to swing.

[0011] Specifically, the through hole is a longitudinal elongated hole, the spring support rod is a round rod, the lower end of the spring support rod stands on the second spring seat, the first spring seat is located above the first spring seat, the upper end of the spring component abuts against the first spring seat, and the lower end of the spring component abuts against the second spring seat.

[0012] For example, the movable pressure frame uses a vertical flat plate, which is a one-piece vertically set flat plate. A row of pressure rollers is installed on the outer surface of the vertical flat plate, and the pressure rollers are arranged longitudinally between each other.

[0013] The beneficial effects of this utility model are as follows: the paper feeding device equipped with auxiliary pressure rollers is conveniently assembled with the movable pressure frame, providing good paper feeding stability and adaptability to paperboards of different thicknesses. The front and rear (input and output ends) of the entire row of pressure rollers can independently rise and fall with the movable pressure frame (front and rear sections), allowing for smooth pressure feeding through coordinated movement. The pressure rollers on the input and output sides do not interfere with each other's normal pressure feeding, resulting in higher efficiency and greater practicality. This paper feeding device can be configured for use in a casing edge-wrapping mechanism. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Referring to the accompanying drawings, in this embodiment, the paper feeding device equipped with an auxiliary pressure roller includes a support frame 1, a paper feeding belt 2, and a pressure roller 3, and also includes a movable pressure frame 4. The pressure roller 3 is arranged above the paper feeding belt 2 so that the pressure roller 3 cooperates with the paper feeding belt 2 to clamp the paperboard and transport it stably.

[0028] Among them, the pressure rollers 3 are arranged longitudinally on the movable pressure frame 4, which can achieve stable clamping and conveying within a certain range during the longitudinal conveying of the cardboard. Moreover, the entire row of multiple pressure rollers 3 can move together with the movable pressure frame 4, and it is relatively convenient to assemble a row of pressure rollers 3 together with the movable pressure frame 4.

[0029] The support frame 1 is equipped with a first swing arm 41 and a second swing arm 42 arranged front and rear. One end of the first swing arm 41 is hinged to the support frame 1, and the other end of the first swing arm 41 is hinged to the movable pressure frame 4. One end of the second swing arm 42 is hinged to the support frame 1, and the other end of the second swing arm 42 is hinged to the movable pressure frame 4, so that the front and rear parts of the movable pressure frame 4 can move up and down respectively. In addition, a spring component 5 is provided between the movable pressure frame 4 and the support frame 1 for pressing the movable pressure frame 4 downward. The spring component 5 provides elastic force to the movable pressure frame 4, so that the movable pressure frame 4 cooperates to apply pressure under the elastic force of the spring component 5, ensuring that each pressure roller 3 applies downward pressure to press the paperboard onto the paper feeding belt 2 and cooperates to clamp and transport the paperboard.

[0030] The pressure rollers 3 are uniformly installed on the movable pressure frame 4 and assembled together with the movable pressure frame 4. The front and rear parts (i.e., the input end and the output end) of the movable pressure frame 4 can move independently up and down. During the paperboard input and output process, the entire row of pressure rollers 3 can move up and down in sequence to apply pressure and convey the paperboard smoothly. The corresponding pressure rollers 3 of the entire row of the movable pressure frame 4 can effectively and stably cooperate to apply pressure one by one. Moreover, even if the paperboard is not completely output at the output end (loses from the pressure roller 3), it does not affect the pressure rollers 3 at the input end to cooperate in applying pressure. The input end of the movable pressure frame 4 can move up and down independently so that the pressure rollers 3 on the input side can apply pressure and cooperate in conveying the paperboard normally (subsequent paperboard input and transfer).

[0031] The paper feeding device equipped with auxiliary pressure rollers is conveniently assembled with the movable pressure frame 4, and has good paper feeding stability. It can adapt to paperboards of different thicknesses. The front and rear (i.e., input and output ends) of the entire row of pressure rollers 3 can move independently up and down with the movable pressure frame 4 (front and rear parts). The entire row of pressure rollers 3 can move up and down in sequence to apply pressure and feed smoothly. The pressure rollers 3 on the input side and the output side do not interfere with each other to apply pressure and feed normally, which is more efficient and more practical.

[0032] Based on the above embodiments, the following optimizations or further explanations can be made.

[0033] For example, the front end of the first swing arm 41 is hinged to the support frame 1, and the rear end of the first swing arm 41 is hinged to the movable pressure frame 4. The front end of the second swing arm 42 is hinged to the support frame 1, and the rear end of the second swing arm 42 is hinged to the movable pressure frame 4. This forms a structure in which the first swing arm 41 and the second swing arm 42 are horizontally arranged between the support frame 1 and the movable pressure frame 4. The first swing arm 41 and the second swing arm 42 swing smoothly in a horizontal position (up and down), resulting in a compact structure.

[0034] For example, the movable pressure frame 4 includes a longitudinal plate portion 43 and a vertical plate portion 44. The longitudinal plate portion 43 is connected to the vertical plate portion 44 and is located below the vertical plate portion 44. The vertical plate portions 44 are arranged front and rear. The first swing arm 41 and the second swing arm 42 are respectively hinged to the corresponding vertical plate portions 44. The movable pressure frame 4 is respectively hinged to the first swing arm 41 and the second swing arm 42 through the corresponding vertical plate portions 44. The space between the front and rear vertical plate portions 44 can be used for the spring component 5, making the structure more reasonable. For example, the movable pressure frame 4 adopts a vertical plate, which is an integral vertically arranged plate. A row of pressure rollers 3 is installed on the outer surface of the vertical plate. The pressure rollers 3 are arranged longitudinally with each other, which is compact and easy to assemble. The integral plate form of the movable pressure frame 4 has good overall integrity, and the pressure rollers 3 have good uniformity after installation.

[0035] For example, the spring components 5 are distributed front and rear so that the front and rear of the movable pressure frame 4 are well subjected to elastic force. In addition, the support frame 1 is provided with a first spring connecting part 51, and the movable pressure frame 4 is provided with a second spring connecting part 52. The spring components 5 are arranged between the first spring connecting part 51 and the second spring connecting part 52 to facilitate the assembly and connection of the corresponding spring components 5. For example, a first spring seat is provided at the first spring connection part 51, and a second spring seat is provided at the second spring connection part 52. A spring support rod 53 is also provided on the second spring seat. The spring component 5 is sleeved on the spring support rod 53. A through hole 54 is provided on the first spring seat for the spring support rod 53 to pass through. There is a fitting gap between the through hole 54 and the spring support rod 53 to allow the spring support rod 53 to swing, ensuring the assembly, connection and operation of the spring component 5. This allows the (front and rear) spring components 5 to smoothly provide elastic force to the movable pressure frame 4 (front and rear parts). This ensures that the front and rear parts (i.e., the input end and the output end) of the movable pressure frame 4 can smoothly apply pressure and cooperate with the paper feeding belt 2 during the independent up and down movement. During the paperboard input and output process, the entire row of pressure rollers 3 can rise and fall in sequence to smoothly apply pressure and convey the paper. The corresponding pressure rollers 3 of the entire row of the movable pressure frame 4 can effectively and stably cooperate to apply pressure one by one. Specifically, the through hole 54 is a longitudinal elongated hole, and the spring support rod 53 is a round rod. The round rod is matched in the longitudinal elongated hole, which is stable in shaking and can stably shake in the vertical plane. The lower end of the spring support rod 53 stands on the second spring seat, and the first spring seat is located above the first spring seat. The upper end of the spring component 5 abuts against the first spring seat, and the lower end of the spring component 5 abuts against the second spring seat. The structure is reasonable, the spring component 5 is easy to assemble, and the spring component 5 runs smoothly, ensuring that the entire row of pressure rollers 3 can rise and fall independently with the front and rear of the movable pressure frame 4, and is easy to process and assemble.

[0036] The paper feeding device can be configured in the edge-sealing mechanism so that the cardboard (including the face paper) to be edge-sealed is fed in, paused for edge-sealing, and then output. The pressure roller 3 is located outside the movable pressure frame 4. The outside of the pressure roller 3 is also equipped with a lifting vertical pressure plate 6 of the edge-sealing mechanism. The vertical pressure plate 6 blocks the inside of the entire row of pressure rollers 3, which can also stabilize the operation of the pressure roller 3. During the up-and-down movement of the pressure roller 3 with the movable pressure frame 4, the vertical pressure plate 6 can cooperate to limit and guide the up-and-down movement of the pressure roller 3. Usually, the lifting stroke of the vertical pressure plate 6 (such as a vertical thin plate) is small. The vertical pressure plate 6 is connected to the lifting pressure drive cylinder 60 to drive the vertical plate to move up and down. Similarly, the up-and-down stroke of the pressure roller 3 is also small, generally only slightly larger than the thickness of the cardboard.
