Abstract
Description
Technical Field
[0001] This utility model belongs to the field of papermaking equipment technology, and in particular relates to a novel connection structure between the cylinder head and the knife holder of a single-cylinder rope cutter. Background Technology
[0002] The rope cutter is used in conjunction with the rope winnowing machine and is located below the rope exit of the winnowing machine. It cuts the winnowed rope at a set frequency to ensure continuous operation of the equipment group. The rope cutter's action of cutting the winnowed rope is mainly achieved by the reciprocating motion of the cylinder head of the single-cylinder rope cutter, which in turn pushes the cutter head forward and backward to achieve the cutting action of advancing and retracting the cutter.
[0003] In traditional setups, the cylinder head and cutter holder of a rope cutter are typically connected by welding or simple bolts. Both of these connection methods have drawbacks in practical applications.
[0004] Using welded connections makes tool holder replacement inconvenient. Since tool holders are consumable parts and need to be replaced when problems occur, this makes maintenance difficult.
[0005] Using a simple bolt connection, the nut may loosen during long-term reciprocating motion, affecting the connection effect.
[0006] Therefore, the applicant proposes a simpler and more reliable connection structure to achieve the connection between the cylinder head and the cutter holder of a single-cylinder rope cutter. Utility Model Content
[0007] In order to solve the problems in the prior art, this utility model provides a novel connection structure between the cylinder head and the cutter holder of a single-cylinder rope cutter.
[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0009] A novel connection structure between the cylinder head and the cutter holder of a single-cylinder rope cutter includes a rope cutter cylinder head and a cutter holder. The connection structure includes a positioning plate with a through hole in the middle. The rope cutter cylinder head passes through the through hole and contacts and engages with the cutter holder. The rope cutter cylinder head is provided with an external thread, and a locking nut is fitted on the external thread. The diameter of the locking nut is larger than that of the through hole and abuts against the positioning plate.
[0010] Connecting blocks are provided on the left and right sides of the positioning plate, and the connecting blocks are located between the positioning plate and the tool holder. The positioning plate, connecting blocks and tool holder are detachably and fixedly connected.
[0011] The connecting block is also provided with a limiting threaded hole, through which a limiting bolt passes, and the end of the limiting bolt abuts against the circumferential surface of the locking nut.
[0012] Furthermore, the positioning plate, connecting block, and tool holder are detachably and fixedly connected in the following manner:
[0013] The positioning plate, connecting block, and tool holder are respectively provided with a first connecting hole, a second connecting hole, and a third connecting hole. The connecting bolt passes through the first connecting hole of the positioning plate and the second connecting hole of the connecting block, and is threadedly connected to the third connecting hole on the tool holder.
[0014] Furthermore, the positioning plate is arranged parallel to the tool holder.
[0015] Furthermore, the outer periphery of the locking nut has multiple planes, and the end of the limiting bolt abuts against one of these planes.
[0016] Furthermore, the locking nut is a hexagonal nut.
[0017] Furthermore, the limiting threaded hole extends in the left-right direction.
[0018] Furthermore, the positioning plate and connecting block are made of steel plate.
[0019] The beneficial effects of this utility model are:
[0020] This invention achieves a reliable connection between the cylinder head and the cutter holder of a single-cylinder rope cutter. Its structure is reasonable and simple, reliable in use, easy to install, disassemble, and operate, and convenient for inspection and maintenance.
[0021] This utility model is equipped with a limit bolt. After the locking nut is adjusted to the appropriate position, the limit bolt is used to tighten the locking nut to prevent it from rotating, thus preventing the locking nut from loosening and ensuring the connection effect.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] like Figures 1 to 2 As shown, this embodiment provides a novel connection structure between the cylinder head and the cutter holder of a single-cylinder rope cutter, including a rope cutter cylinder head 1 and a cutter holder 2.
[0027] The connecting structure includes a positioning plate 3 arranged parallel to the cutter holder. A through hole is provided in the middle of the positioning plate 3, through which the rope cutting machine cylinder head 1 passes and contacts and engages with the cutter holder 2. The rope cutting machine cylinder head 1 is provided with an external thread, and a locking nut 4 is fitted on the external thread. The diameter of the locking nut 4 is larger than that of the through hole and abuts against the positioning plate 3.
[0028] Connecting blocks 5 are respectively provided on the left and right sides of the positioning plate 3, and the connecting blocks 5 are located between the positioning plate 3 and the tool holder 2. The positioning plate 3, the connecting blocks 5 and the tool holder 2 are respectively provided with a first connecting hole, a second connecting hole and a third connecting hole. The connecting bolt 6 passes through the first connecting hole of the positioning plate 3 and the second connecting hole of the connecting block 5, and is threadedly connected to the third connecting hole on the tool holder 2, thereby realizing the detachable fixed connection of the positioning plate 3, the connecting blocks 5 and the tool holder 2.
[0029] The connecting block 5 is also provided with a limiting threaded hole extending in the left and right direction. A limiting bolt 7 passes through the limiting threaded hole, and the end of the limiting bolt 7 abuts against the circumferential surface of the locking nut.
[0030] In this embodiment, the locking nut 4 is a hexagonal nut, and the outer periphery of the locking nut 4 has six planes. The end of the limiting bolt 7 abuts against one of the planes.
[0031] In this embodiment, the positioning plate 3 and the connecting block 5 are made of steel plates to ensure connection strength and durability.
[0032] The assembly process and working principle of this utility model are as follows:
[0033] First, fit the positioning plate 3 onto the cylinder head 1 of the rope cutter, then screw in the locking nut 4. Connect the positioning plate 3 and the connecting block 5 to the cutter holder 2 using the connecting bolts 6. Then, after adjusting the locking nut 4 to the appropriate position, use the limit bolts 7 to tighten the locking nut 4 to prevent it from rotating, thus preventing the locking nut 4 from loosening and ensuring the connection effect.
[0034] The feed process is driven forward by the main body of the rope cutter cylinder 1, while the retraction process is driven backward by the locking nut 4 pulling the cutter holder 2.
[0035] This invention achieves a reliable connection between the cylinder head and the cutter holder of a single-cylinder rope cutter. Its structure is reasonable and simple, reliable in use, easy to install, disassemble, and operate, and convenient for inspection and maintenance.
