Description

Technical Field

[0001] This utility model relates to the field of polyester fiber processing technology, and in particular to a filament cutting machine that is easy to maintain. Background Technology

[0002] In many industries such as textiles and cable processing, wire tow cutting machines are indispensable key equipment, and their operating status directly affects production efficiency and product quality.

[0003] Currently, the drive mechanism and cutting mechanism of wire tow cutting machines are often closely connected, lacking clear separation and maintenance space. When the wire tow is wrapped around the cutting mechanism, due to space constraints, maintenance personnel cannot directly operate the cutting mechanism. To clean the wrapped wire tow or repair the cutting mechanism, it is often necessary to disassemble the entire drive mechanism, which not only consumes a lot of manpower and time but also increases the complexity and difficulty of maintenance, seriously affecting production progress. Moreover, as the core component of the wire tow cutting machine, the cutting mechanism is prone to damage due to frequent cutting during use. However, because it is integrated with the drive mechanism, each time the cutting mechanism is repaired or replaced, a large-scale disassembly of the entire equipment is required, resulting in high maintenance costs. Therefore, it is necessary to design a wire tow cutting machine that is easy to maintain. Utility Model Content

[0004] The purpose of this invention is to provide a wire tow cutting machine that is easy to maintain, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A filament cutting machine that is easy to maintain includes:

[0007] A cutting machine, comprising a drive mechanism and a cutting mechanism, wherein the cutting mechanism is disposed to the right of the drive mechanism and the drive mechanism is used to drive the cutting mechanism to perform cutting;

[0008] The maintenance unit is located on the right side of the cutting mechanism, and the maintenance unit facilitates the maintenance of the cutting mechanism.

[0009] By adopting the above technical solution, the maintenance unit is located on the right side of the cutting mechanism, forming a clear maintenance channel. When the wire bundle is wrapped around the cutting mechanism, the cutting mechanism can be maintained and cleaned through the maintenance unit without disassembling the drive mechanism. This facilitates manual operation and significantly reduces maintenance time and complexity. Moreover, as the cutting mechanism is a vulnerable mechanism, the independent setting of the drive mechanism and the cutting mechanism facilitates direct replacement and maintenance of the cutting mechanism.

[0010] In a further embodiment, the maintenance unit includes:

[0011] The cover has a completely open structure at both its left and bottom ends. The open end of the cover is fixedly connected to the right side of the cutting machine. The right side of the cover has a through mounting port.

[0012] The door panel is disposed within the mounting opening. The door panel includes a first side panel and a second side panel. The first side panel is disposed on the front side of the second side panel. The front side of the first side panel is hinged to the cover. The rear side of the second side panel is hinged to the cover. A first magnet is disposed inside the top and bottom of the rear side of the first side panel. A second magnet is disposed inside the top and bottom of the front side of the second side panel.

[0013] By adopting the above technical solution, the door panel is composed of a first side panel and a second side panel, both of which are hinged to the cover, making the first side panel and the second side panel open and close flexibly. The design of the first magnet inside the first side panel and the design of the second magnet inside the second side panel can make the door panel close tightly, which is convenient for quick access for maintenance and can effectively prevent dust, thereby reducing the difficulty of maintenance.

[0014] In a further embodiment, the drive mechanism includes:

[0015] The outer casing has an internal partition that divides the interior of the outer casing into an upper chamber and a lower chamber. An inspection door is provided on the rear side of the upper chamber of the outer casing. A through hole is provided on the top right side of the outer casing, and a first bearing is fixedly installed in the through hole.

[0017] The transmission device includes a bearing housing, a main shaft, a driven wheel, a transmission belt, and a coupling disc. The axes of the main shaft and the coupling disc are on the same horizontal straight line. The coupling disc is fixedly connected to the right end of the main shaft. A through hole is provided on the top side of the partition plate. The bearing housing is spaced apart on the right side of the through hole and fixedly installed on the top of the partition plate. Both ends of the main shaft pass through and extend to the outside of the bearing housing. The driven wheel is sleeved on the left end of the main shaft. One end of the transmission belt is sleeved on the outer wall of the driven wheel, and the other end of the transmission belt passes through the through hole and is sleeved on the outer wall of the drive wheel.

Multiple blades are provided. The diameter of the rear flange is the same as the outer diameter of the front flange. The rear flange and the front flange are screwed to both sides of the cutter holder. Multiple blades are evenly installed in the cutter head support on the cutter holder along the periphery at equal intervals. The cutter cover is screwed to the front flange to protect the blades.

[0021] The pressure roller assembly includes a pressure roller, a pressure roller shaft, and a cylinder. The cylinder is fixedly installed on the right side of the housing, and the pressure roller shaft is fixedly installed on the cylinder. A pair of second bearings are provided inside the pressure roller, and the pair of second bearings are fixedly installed on the right end of the pressure roller shaft.

[0022] By adopting the above technical solution, multiple notches are axially set on the centrifugal side periphery of the rear flange. The long filament bundle is tied to the rear flange through the notches. Then, the long filament bundle is wound around the cutter head by high-speed rotation. The pressure roller squeezes the outer layer of the filament bundle of the cutter head and rotates with the rotation of the cutter head. Under the action of the cylinder, the pressure roller squeezes the outer layer of the filament bundle of the cutter head, so that the long filament bundle in the inner layer is evenly cut into short filament bundles by multiple blades on the cutter head. The different number of blades can also accommodate filament bundles of different lengths and thicknesses.

[0023] In a further embodiment, a feed inlet is provided at the top rear side of the frame, and a discharge outlet is provided at the bottom of the frame.

When the wire bundle is wrapped around the cutting mechanism, the cutting mechanism can be maintained and cleaned simply by using the maintenance unit. There is no need to disassemble the drive mechanism, which is convenient for manual operation and significantly reduces maintenance time and complexity. Moreover, as the cutting mechanism is a vulnerable mechanism, by setting the drive mechanism and the cutting mechanism independently, it is convenient to directly replace and maintain the cutting mechanism.
