Description

Technical Field

[0001] This utility model relates to the field of paper cutter technology, and more particularly to a hydraulic paper roll cutter. Background Technology

[0002] Currently, there are many paper cutting devices available, and their basic structures are largely the same. Paper cutters generally include a blade holder, a cutter, and a cutting platform. The cutter is mounted on the blade holder and connected to the push rod of a hydraulic cylinder. The blade holder typically moves vertically. Paper is placed on the cutting platform, and the cutter cuts the paper by moving up and down. However, in existing paper cutting equipment, after the cutter cuts the roll of paper, the output end of the hydraulic cylinder extends, tilting the cutting platform and dumping the roll of paper onto the conveyor belt below the cutting equipment in one go. This feeding method easily causes the roll to accumulate on the conveyor belt, preventing the conveyor belt from operating properly. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic paper roll cutter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hydraulic paper roll cutter, comprising a base and a top seat mounted on the base, a fixed frame for placing paper rolls is mounted on the base, and a cutter for cutting the paper rolls is mounted on the top seat. The fixed frame includes a support plate rotatably mounted on the base and a baffle rotatably connected to the support plate. A rear hydraulic cylinder is installed between the baffle and the base, and a front hydraulic cylinder is installed between the support plate and the base. The first feeding occurs when the output end of the rear hydraulic cylinder retracts, and the second feeding occurs when the output end of the front hydraulic cylinder extends.

[0005] With the rear hydraulic cylinder extended, the output end of the rear hydraulic cylinder forms a V-shape with the baffle and support plate, so that the outer circumference of the paper roll is tangent to the baffle and support plate respectively, fixing the paper roll between the support plate and the baffle. This allows for the cutting of cylindrical paper rolls. After the cutter has completely cut the paper roll, the output end of the rear hydraulic cylinder retracts, and the paper roll on the baffle is fed out for the first time. After all the paper rolls on the baffle fall into the conveyor belt, the output end of the front hydraulic cylinder extends to feed the paper roll on the support plate a second time. This two-stage feeding of the paper roll ensures that the conveyor belt can smoothly transport the paper roll while ensuring the normal operation of the conveyor belt.

[0006] In a preferred embodiment of the present invention, the top seat includes a bracket mounted parallel to the base. A top plate is fixedly mounted on the top of the bracket. Two cutting cylinders are mounted on the top plate. The output end of the cutting cylinder passes through the top plate and is located between the top plate and the fixed frame. The cutter is fixedly mounted on the output end of the cutting cylinder.

[0007] In a preferred embodiment of the present invention, guide components are provided at both ends of the cutter. The guide components include two parallel guide shafts. One end of the guide shaft is fixedly mounted on the top plate, and the other end of the guide shaft is fixedly mounted on the base. A linear bearing is slidably mounted on the guide shaft, and the linear bearing is fixedly connected to the cutter.

[0008] In a preferred embodiment of the present invention, the support plate includes a straight section and an extended section, the extended section and the straight section being arranged at an angle; a support rod is provided between the end of the extended section and the base, and the support rod is rotatably connected to the extended section of the support plate.

[0009] In a preferred embodiment of this utility model, a front hydraulic cylinder is installed between the support plate and the base, and the two ends of the front hydraulic cylinder and the rear hydraulic cylinder are rotatably connected between the support plate and the base, respectively.

[0015] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1 As shown, the hydraulic paper roll cutter provided in this embodiment includes a base 01 and a top seat 02 mounted on the base 01. A fixing frame 03 for placing paper rolls is mounted on the base 01, and a cutter 04 for cutting the paper rolls is mounted on the top seat 02. The top seat 02 includes four support columns 06 mounted parallel to the base 01. Every two support columns 06 form a bracket 05, which is fixedly mounted on one side of the base 01. A top plate 07 is fixedly mounted on the top of the bracket 05. Two cutter cylinders 08 are mounted on the top plate 07. The output end of the cutter cylinder 08 passes through the top plate 07 and is located between the top plate 07 and the fixing frame 03. The cutter 04 is fixedly mounted on the output end of the cutter cylinder 08, and guide components are provided at both ends of the cutter 04. When the cutter cylinder 08 drives the cutter 04 to move up and down between the top plate 07 and the fixed frame 03, the guide assembly provides guidance for the cutter 04, enabling it to move linearly during the up-and-down movement. The guide assembly includes two parallel guide shafts 09, one end of which is fixedly mounted on the top plate 07, and the other end of which is fixedly mounted on the base 01. A linear bearing 10 is slidably mounted on the guide shaft 09, and the linear bearing 10 is fixedly connected to the cutter 04.

[0017] The fixed frame 03 includes a support plate 11 rotatably mounted on the base 01 and a baffle 12 rotatably connected to the support plate 11 via a hinge. The connection between the support plate 11 and the baffle 12 is located above the connection between the support plate 11 and the base 01. A rear hydraulic cylinder 13 is installed between the baffle 12 and the base 01. The support plate 11 includes a straight section 14 and an extension section 15, which are angled together. A support rod 16 is provided between the end of the extension section 15 and the base 01. When a cylindrical roll of paper is placed on the fixed frame 03, the roll contacts the support plate 11. The support rod 16 prevents the support plate 11 from rotating towards the base 01 and provides support for the support plate 11. At the same time, the output end of the rear hydraulic cylinder 13 extends, making the extension section 15 on the baffle 12 and the support plate 11 form a V-shape, so that the outer circumference of the roll of paper is tangent to the baffle 12 and the support plate 11, respectively. The roll of paper is fixed between the support plate 11 and the baffle 12. Then, the roll of paper is cut by the cutter 04. After the roll of paper is cut, the output end of the rear hydraulic cylinder 13 retracts, causing the baffle 12 to rotate. The roll of paper that has been cut on the baffle 12 can fall smoothly from the fixed frame 03 onto the conveyor belt on one side of the base 01. At the same time, a front hydraulic cylinder 18 is installed between the support plate 11 and the base 01. Then, the output end of the front hydraulic cylinder 18 extends, causing the support plate 11 to rotate. This allows the roll of paper that has been cut on the support plate 11 to fall smoothly from the fixed frame 03 onto the conveyor belt on one side of the base 01. This is equivalent to two feedings after the roll of paper is cut, thus ensuring that the conveyor belt can operate normally.

[0018] A connecting seat 17 is provided between the support rod 16 and the support plate 11. The connecting seat 17 includes two connecting plates 19 mounted parallel to each other on the base 01. Both the connecting plates 19 and the support rod 16 are provided with connecting holes, and connecting shafts are provided in the connecting holes. Through the cooperation of the connecting shafts and connecting holes, the support rod 16 is rotatably mounted on the support plate 11. Compared with fixing the support rod 16 to the support plate 11, rotatably mounting the support rod 16 to the support plate 11 allows the support rod 16 to fit snugly against the support plate 11 during transportation, thus reducing its energy consumption during transportation. At the same time, a slot adapted to the support rod 16 is provided on the base 01. Through the setting of the slot, when the support rod 16 is supported between the base 01 and the support plate 11, there will be no displacement between the support rod 16 and the base 01.

[0019] Multiple support seats 20 are fixedly installed on both the support plate 11 and the base 01. Each support seat 20 is equipped with a rotating shaft, which allows the support plate 11 to be rotatably connected to the base 01.

[0020] A cylinder seat 21 is provided between the front cylinder 18 and the support plate 11. The cylinder seat 21 includes two fixing plates fixedly mounted on the support plate 11. The fixing plates are provided with fixing holes. The output end of the front cylinder 18 is located between the two fixing plates. A fixing shaft is provided in the fixing hole. The front cylinder 18 and the support plate 11 are rotatably connected through the fixing shaft and the fixing hole. By installing the same cylinder seat 21 between the front cylinder 18 and the base 01, both ends of the front cylinder 18 are rotatably connected to the support plate 11 and the base 01, respectively. The same method is used to rotatably connect both ends of the rear cylinder 13 to the support plate 11 and the base 01, respectively.

[0021] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
