Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, specifically a wire cutting machine. Background Technology

[0002] In the process of chemical fiber production, chemical fiber spindles are prone to filament breakage during processing. Broken spindles need to be recycled and reprocessed. Fiber cutting is a key step in recycling and directly affects the efficiency of subsequent processing and product quality. Currently, fiber cutting mainly relies on manual operation or simple mechanical cutting equipment. Manual cutting requires operators to continuously observe the spindle's condition, which is labor-intensive and inefficient. Prolonged operation can easily lead to visual fatigue, causing deviations in the cutting position and increasing the difficulty of subsequent reprocessing. Existing simple mechanical cutting equipment lacks precise orientation of the spindle (winding drum), making it difficult to ensure stable contact between the cutting blade and the filament. This not only results in incomplete cutting and uneven cross-sections, affecting the quality of recycled filaments, but also accelerates wear due to uneven force on the cutting blade, increasing equipment maintenance costs and downtime for repairs. Therefore, developing a device that can automatically orient the winding drum and ensure stable cutting of broken filaments in chemical fiber spindles is of great significance for improving the efficiency of broken filament recycling and processing and ensuring the smooth operation of subsequent chemical fiber production. Utility Model Content

[0003] The purpose of this utility model is to provide a wire cutting machine to solve the problems mentioned in the background art, such as high labor intensity, low efficiency, and easy deviation in cutting position leading to incomplete wire cutting and uneven cross-section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wire cutting machine, comprising a horizontal plate, a rotating mounting cylinder mounted on the upper end of the horizontal plate, and a winding cylinder engaged on the outer surface of the mounting cylinder, a clearance groove being provided on the outer surface of the winding cylinder, and an directional cutting mechanism being provided on the outer surface of the horizontal plate, thereby achieving stable cutting of the wire wound on the surface of the winding cylinder by automatically orienting the winding cylinder.

[0005] The directional cutting mechanism includes: a vertical plate, an electric push rod fixedly installed on the outer surface of the vertical plate, a sliding plate slidably installed at one end of the electric push rod, and a cutting blade fixedly installed on the outer surface of the sliding plate facing the mounting cylinder; a synchronization plate is provided on the upper surface of the horizontal plate on the lower end of the vertical plate; a first motor is fixedly installed inside the middle section side surface of the vertical plate, and one end of the output shaft of the first motor passes through the outer surface of the vertical plate, and a lever is fixedly connected to one end of the output shaft of the first motor.

[0006] The directional cutting mechanism further includes: a second motor, which is fixedly installed inside the upper surface of the horizontal plate directly below the mounting cylinder; an extrusion plate is fixedly connected to the upper end of the output shaft of the second motor; a baffle is fixedly installed on the lower inner surface of the mounting cylinder; a sliding positioning block is installed on the upper surface of the horizontal plate on one side of the mounting cylinder; a contact switch is fixedly installed inside the upper surface of the horizontal plate on one side of the positioning block; and an obstruction sensor is fixedly installed on the upper surface of the horizontal plate on one side of the mounting cylinder.

[0007] Preferably, the relief grooves are symmetrically arranged on both outer surfaces of the winding drum, and the lower end of the relief grooves has a chamfered design that is smaller at the top and larger at the bottom.

[0008] The above technical solution utilizes a chamfered V-shape design to facilitate quick engagement between the positioning block and the clearance groove, providing guidance for the automatic orientation of the winding drum. This also reduces mechanical wear during engagement and ensures accurate positioning during the rotation of the winding drum.

[0009] Preferably, the lower end of the sliding plate is slidably connected to the synchronization plate, and a spring is connected between the synchronization plate and the horizontal plate, and adjacent synchronization plates are fixedly connected.

[0010] Using the above technical solution, the elastic restoring effect of the spring causes the synchronous plate to drive the sliding plate to reciprocate. Combined with the rotation of the dial plate, a stable cutting blade lifting rhythm is formed. The fixed connection of adjacent synchronous plates ensures that multiple sets of cutting blades move synchronously, improving cutting efficiency and consistency.

[0011] Preferably, both ends of the dial plate are semi-circular, and the diameters of the semi-circular portions at both ends of the dial plate are different. The end of the dial plate with a larger diameter is fixedly connected to the output shaft of the first motor. The dial plate is located between the lower surface of the synchronizing plate and the upper surface of the horizontal plate.

[0012] By adopting the above technical solution, the cutting blade is driven to complete the "lift-cut-reset" cycle by lifting or releasing the synchronous plate in conjunction with the spring. This achieves automated cutting using a simple mechanical structure, reducing equipment complexity and energy consumption.

[0013] Preferably, the extrusion plate and the baffle are at the same horizontal height, and the outer surface of one side of the extrusion plate is in contact with the outer surface of the baffle.

[0014] By adopting the above technical solution, when the second motor drives the extrusion plate to rotate, it can smoothly push the mounting cylinder and the winding cylinder to rotate, avoiding the winding cylinder from shifting due to uneven force, thus laying the foundation for the precise engagement of the subsequent positioning block.

[0015] Preferably, the positioning block is an L-shaped design with a horizontal protrusion at the lower end, and a spring is connected between the positioning block and the horizontal plate. The horizontal protrusion at the lower end of the positioning block is located directly above the contact switch. The positioning block is installed by engaging with the winding drum through a relief groove, and the upper end of the positioning block is in contact with the arc-shaped chamfered outer surface of the lower end of the relief groove.

[0016] Using the above technical solution, the L-shaped structure and spring work together to achieve the dual functions of "pre-locking and precise positioning": during the initial locking, the transverse protrusion triggers the contact switch to stop the motor rotation to avoid rigid impact, and the spring pushes the positioning block to slide further along the chamfered slope of the relief groove until it is fully locked, ensuring that the orientation accuracy of the winding drum meets the cutting requirements.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This wire cutting machine:

[0018] 1. An directional cutting mechanism is installed, which realizes automatic orientation of the winding drum and effectively solves the problem of difficulty in ensuring stable contact between the cutting blade and the yarn during cutting in existing equipment. Specifically, the first motor drives the dial plate to rotate, and in conjunction with the linkage structure of the synchronous plate, sliding plate and cutting blade, the cutting blade can accurately and stably cut the yarn on the surface of the winding drum. This avoids the cutting position deviation caused by visual fatigue during manual operation, and greatly improves the cutting efficiency. At the same time, the stable contact between the cutting blade and the yarn ensures the thoroughness of the cut and the neatness of the cut surface, which significantly improves the quality of the recycled yarn and provides high-quality raw materials for subsequent chemical fiber production and processing.

[0019] 2. Through the coordinated work of components such as the extrusion plate, baffle, and positioning block, the precise positioning of the winding drum during the cutting process is ensured, reducing wear on the cutting blade caused by uneven force, and lowering the equipment maintenance cost and downtime for repair.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model provides a technical solution: a wire cutter.

[0030] Example 1: This example discloses: a horizontal plate 1, a rotating mounting cylinder 2 installed at the upper end of the horizontal plate 1, and a winding cylinder 3 engaged on the outer surface of the mounting cylinder 2. A clearance groove 4 is provided on the outer surface of the winding cylinder 3. A directional cutting mechanism is provided on the outer surface of the horizontal plate 1. The winding cylinder 3 is automatically oriented to achieve stable cutting of the winding thread on the surface of the winding cylinder 3.

[0031] The directional cutting mechanism includes: a vertical plate 5, an electric push rod 6 fixedly installed on the outer surface of the vertical plate 5, a sliding plate 7 slidably installed on one end of the electric push rod 6, and a cutting blade 8 fixedly installed on the outer surface of the sliding plate 7 facing the mounting cylinder 2; a synchronization plate 9 is provided on the upper surface of the horizontal plate 1 on the lower end of the vertical plate 5; a first motor 10 is fixedly installed inside the middle section side surface of the vertical plate 5, and one end of the output shaft of the first motor 10 passes through the outer surface of the vertical plate 5, and a lever plate 11 is fixedly connected to one end of the output shaft of the first motor 10.

[0032] The relief grooves 4 are symmetrically arranged on both outer surfaces of the winding drum 3, and the lower end of the relief grooves 4 has a chamfered design with the upper part smaller than the lower part.

[0033] The lower end of the sliding plate 7 is slidably connected to the synchronous plate 9, and a spring is connected between the synchronous plate 9 and the horizontal plate 1, and adjacent synchronous plates 9 are fixedly connected.

[0034] Both ends of the lever 11 are semi-circular, and the diameters of the semi-circular parts at both ends of the lever 11 are different. The end of the lever 11 with a larger diameter is fixedly connected to the output shaft of the first motor 10. The lever 11 is located between the lower surface of the synchronous plate 9 and the upper surface of the horizontal plate 1.

[0035] When it is necessary to cut the wire on the surface of the winding spool 3 mounted on the surface of the mounting cylinder 2 on the horizontal plate 1, the first motor 10 inside the side surface of the vertical plate 5 starts, and its output shaft drives the dial plate 11 to rotate. During the rotation, the smaller diameter end of the dial plate 11 will intermittently push up the synchronous plate 9. The synchronous plate 9 is slidably connected to the sliding plate 7, and adjacent synchronous plates 9 are fixedly connected. When the synchronous plate 9 is pushed up, it will drive the sliding plate 7 to slide upward, thereby causing the cutting blade 8 fixed on the sliding plate 7 to move upward. When the dial plate 11 continues to rotate and no longer pushes up the synchronous plate 9, the synchronous plate 9 and the sliding plate 7 are reset under the action of the spring, and the cutting blade 8 moves downward to complete one cutting action.

[0036] The symmetrical relief grooves 4 on the outer surface of the winding drum 3 have a chamfered lower end to facilitate the engagement and installation of the positioning block 15 with the winding drum 3. At the same time, they provide a certain guiding effect for the rotation of the winding drum 3. During the cutting process, the electric push rod 6 can adjust the initial position of the sliding plate 7 according to the actual situation such as the thickness of the wire winding to ensure that the cutting blade 8 can accurately cut the wire and achieve stable cutting of the wire wound on the surface of the winding drum 3. This solves the problems of low efficiency and easy position deviation of manual cutting.

[0037] Example 2: This example discloses, based on Example 1, that the directional cutting mechanism further includes: a second motor 12, which is fixedly installed inside the upper surface of the horizontal plate 1 directly below the mounting cylinder 2; an extrusion plate 13 is fixedly connected to the upper end of the output shaft of the second motor 12; a baffle 14 is fixedly installed on the inner side surface of the lower end of the mounting cylinder 2; a sliding positioning block 15 is installed on the upper surface of the horizontal plate 1 on one side of the mounting cylinder 2; a contact switch 16 is fixedly installed inside the upper surface of the horizontal plate 1 on one side of the positioning block 15; and an obstruction sensor 17 is fixedly installed on the upper surface of the horizontal plate 1 on one side of the mounting cylinder 2.

[0038] The extrusion plate 13 and the baffle 14 are at the same horizontal height, and the outer surface of one side of the extrusion plate 13 is in contact with the outer surface of the baffle 14;

[0039] The positioning block 15 has an L-shaped design with a horizontal protrusion at the lower end, and a spring is connected between the positioning block 15 and the horizontal plate 1. The horizontal protrusion at the lower end of the positioning block 15 is located directly above the contact switch 16. The positioning block 15 is engaged with the winding drum 3 through the relief groove 4, and the upper end of the positioning block 15 is in contact with the arc-shaped chamfered outer surface at the lower end of the relief groove 4.

[0040] After the winding drum 3 is installed on the mounting cylinder 2, the second motor 12 is started. Its output shaft drives the extrusion plate 13 to rotate. Since the extrusion plate 13 and the baffle 14 are at the same horizontal height and their outer surfaces are in contact, the rotation of the extrusion plate 13 will push the mounting cylinder 2 and the winding drum 3 to rotate until the positioning block 15 and the relief groove 4 of the winding drum 3 are initially engaged. At this time, the horizontal protrusion at the lower end of the positioning block 15 will leave the contact switch 16, so that the contact switch 16 stops sending an electrical signal to the second motor 12. Under the support of the spring, the positioning block 15 compresses the chamfered slope at the lower end of the relief groove 4 to make the winding drum 3 continue to rotate into place. At the same time, the blocking sensor 17 detects the signal that the winding drum 3 is in place. The equipment control system determines that the winding drum 3 has been accurately oriented. After that, the first motor 10, the dial plate 11, the synchronization plate 9, the sliding plate 7 and the cutting blade 8 perform the cutting action in accordance with the method of Embodiment 1.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
