Description

Technical Field

[0001] This utility model belongs to the field of wire drawing technology, specifically relating to a wire drawing machine feeding device. Background Technology

[0002] The feeding device of a wire drawing machine is an important component that ensures the smooth and stable entry of raw materials into the extrusion system. Wire drawing machines are mainly used to heat plastic or metal materials at high temperatures and extrude them into long, thin filaments using a screw. The function of the feeding device is to effectively supply the raw materials into the extruder, ensuring the continuity and stability of the production process.

[0003] Problems with existing technology:

[0004] Existing wire drawing machines mostly use woven bags for easy material handling. However, when using them, workers need to cut the bags open and then pour the wire material into the feed hopper. This process is mostly done manually, which can damage the workers' back muscles when lifting the bags. Moreover, the cutting process is cumbersome and can easily spill, causing unnecessary waste. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a wire drawing machine. By rotating the winding traction shaft and cooperating with the guide wheel frame to change the direction of the traction rope, the feeding cart can be pulled to the top of the feeding hopper, so that the operator does not need to manually lift the woven bags of wire drawing material, reducing waist injuries. The labor-saving disc can reduce torque, and the design of the blade inside the sliding shell can cut the woven bags of wire drawing material during the process of moving to the top of the feeding hopper without much operation. Moreover, the blade can be hidden when not in use to prevent accidental cuts.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A wire drawing machine feeding device includes: a base plate, a feeding hopper is provided at the top of one end of the base plate, a feeding trolley is provided at the top of the other end of the base plate, a track is fixedly connected to the top of the feeding hopper, and one end of the track extends to a position below the feeding trolley and is fixedly connected to the base plate.

[0008] A blower is installed on one side below the feed hopper, and a feeding pipe is installed on the other side of the feed hopper. The output end of the blower passes through the feed hopper and is connected to the feeding pipe. A guide wheel frame is installed on the side of the feed hopper away from the feeding trolley. Guide wheels are installed at the top and bottom of the guide wheel frame. A winding traction shaft is rotatably connected to the top of the bottom plate on the side of the feed hopper away from the guide wheel frame via a support leg. A traction rope is fixedly connected to the side of the feeding trolley close to the feed hopper. The traction rope is wound up to the outer sides of both ends of the winding traction shaft via the guide wheels.

[0009] The feed hopper is provided with a sliding shell inside on the side near the winding traction shaft. A one-way bearing is fixedly installed on the winding traction shaft at the position corresponding to the sliding shell. The sliding shell is located above the one-way bearing.

[0010] The loading trolley includes two arc-shaped carrier plates, which are symmetrically arranged and have a knife groove in the middle. Rollers are rotatably mounted on the bottom of each arc-shaped carrier plate and are slidably connected to a track. Multiple anti-slip grooves are arrayed on the surface of each arc-shaped carrier plate.

[0011] The sliding shell is fixedly connected to the feed hopper. A reciprocating plate is vertically slidably installed inside the sliding shell. A blade is fixedly connected to the top of the reciprocating plate, and a connecting rod is fixedly connected to the bottom of the reciprocating plate. A limiting ring is sleeved in the middle of the connecting rod, and the limiting ring is fixedly connected to the feed hopper through the connecting rod.

[0012] A reciprocating wheel is rotatably connected to one side of the base plate corresponding to the one-way bearing via a connecting frame. The reciprocating wheel meshes with the one-way bearing. A transmission rod is provided on one side of the reciprocating wheel. Transmission pins are fixedly installed at both ends of the transmission rod corresponding to the reciprocating wheel and the connecting rod. Both ends of the transmission rod are rotatably connected to the two transmission pins respectively.

[0013] The one-way bearing has multiple reciprocating wheels fixedly mounted on its surface in a ring array, and the reciprocating wheels are in contact with the oscillating transmission bar.

[0014] A force-saving disc is coaxially fixedly connected to one side of the winding traction shaft.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention allows the loading trolley to be pulled to the top of the feeding hopper by rotating the winding traction shaft and changing the direction of the traction rope in cooperation with the guide wheel frame. This eliminates the need for workers to manually lift the woven bags of filament material, reducing back injuries. The diameter of the labor-saving disc is larger than the diameter of the winding traction shaft, which reduces torque.

[0017] This invention, through the design of the blade inside the sliding shell, enables the woven bag of filament material to be cut open during its movement to the top of the feed hopper without much operation, and the blade can be hidden when not in use to prevent accidental cuts.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-2 As shown, a wire drawing machine feeding device includes: a base plate 1, a feeding hopper 2 is provided at the top of one end of the base plate 1, and a feeding trolley 3 is provided at the top of the other end of the base plate 1. A rail 4 is fixedly connected to the top of the feeding hopper 2, and one end of the rail 4 extends to a position below the feeding trolley 3 and is fixedly connected to the base plate 1; a fan 8 is provided on one side below the feeding hopper 2, and a feeding pipe 9 is provided on the other side of the feeding hopper 2. The output end of the fan 8 passes through the feeding hopper 2 and is connected to the feeding pipe 9. A guide wheel frame 5 is provided on the side of the feeding hopper 2 away from the feeding trolley 3. Guide wheels are provided at both the top and bottom of the frame 5. The top of the bottom plate 1, corresponding to the side of the feed hopper 2 away from the guide wheel frame 5, is rotatably connected to the winding traction shaft 6 via the support leg. The side of the loading trolley 3 near the feed hopper 2 is fixedly connected to the traction rope 7. The traction rope 7 is wound around the outer sides of both ends of the winding traction shaft 6 via the guide wheels. A sliding shell 201 is provided inside the side of the feed hopper 2 near the winding traction shaft 6. A one-way bearing 601 is fixedly installed on the winding traction shaft 6 at the position corresponding to the sliding shell 201. The sliding shell 201 is located above the one-way bearing 601.

[0027] When feeding is required, the woven bag of drawing material is placed above the feeding trolley 3, and then the feeding trolley 3 is pulled to the position above the feeding hopper 2 by rotating the winding traction shaft 6. The blade inside the sliding shell 201 is used to cut the woven bag so that the drawing material inside flows into the feeding hopper 2. The bottom of the feeding hopper 2 is provided with a reserved opening, through which the drawing material can flow into the pipe between the feeding pipe 9 and the blower 8. The drawing material is blown into the drawing machine through the feeding pipe 9 by starting the blower 8.

[0028] See attached document Figure 3 The loading trolley 3 includes two arc-shaped carrier plates 301. The two arc-shaped carrier plates 301 are symmetrically arranged and have a knife groove 302 in the middle. Rollers are rotatably installed on the bottom of the arc-shaped carrier plates 301. The rollers are slidably connected to the track 4. Multiple anti-slip grooves 303 are arrayed on the surface of the arc-shaped carrier plates 301.

[0029] According to the above structure, the woven bag of wire drawing material is placed above the arc-shaped carrier plate 301. When the loading trolley 3 moves upward along the track 4, the anti-slip groove 303 is used to prevent it from slipping, and the knife groove 302 is used for the blade to pass through.

[0030] See attached document Figures 4-5 The sliding shell 201 is fixedly connected to the feed hopper 2. A reciprocating plate 202 is vertically slidably installed inside the sliding shell 201. A blade is fixedly connected to the top of the reciprocating plate 202, and a connecting rod 204 is fixedly connected to the bottom of the reciprocating plate 202. A limiting ring 203 is sleeved in the middle of the connecting rod 204. The limiting ring 203 is fixedly connected to the feed hopper 2 through the connecting rod. A reciprocating wheel 602 is rotatably connected to one side of the bottom plate 1 corresponding to the one-way bearing 601 through a connecting frame. The reciprocating wheel 602 is meshed with the one-way bearing 601. A transmission rod 603 is provided on one side of the reciprocating wheel 602. Transmission pins are fixedly installed at both ends of the transmission rod 603 corresponding to the reciprocating wheel 602 and the connecting rod 204. The two ends of the transmission rod 603 are rotatably connected to the two transmission pins respectively. A force-saving disc 10 is coaxially fixedly connected to one side of the winding traction shaft 6.

[0031] According to the above structure, when the winding traction shaft 6 is rotated clockwise, it pulls the loading trolley 3 and the woven bag of drawing material placed above it to move towards the top of the feeding hopper 2. At this time, the one-way bearing 601 also rotates. Since the one-way bearing 601 is meshed with the reciprocating wheel 602, when the one-way bearing 601 rotates, it drives the reciprocating wheel 602 to rotate. The transmission rod 603 on one side of the reciprocating wheel 602 moves vertically under the drive of the reciprocating wheel 602. Since one end of the transmission rod 603 is rotatably connected to the connecting rod 204 and the connecting rod 204 is limited... The position ring 203 is vertically slidably installed inside. When the transmission pin is at the upper end of the rotating reciprocating wheel 602, the transmission rod 603 reaches its highest position. When the transmission pin is at the upper end of the rotating reciprocating wheel 602, the transmission rod 603 reaches its lowest position. Thus, the connecting rod 204 realizes vertical reciprocating motion through the transmission rod 603. The reciprocating plate 202 at the top of the connecting rod 204 reciprocates vertically inside the sliding shell 201, thereby driving the blade to reciprocate at the top of the feed hopper 2, realizing the cutting of the upcoming woven bag of filament material.

[0032] The inner ring of the one-way bearing 601 is fixedly connected to the winding traction shaft 6, and the outer ring of the one-way bearing 601 is rotatably connected to both sides of the outer ring. The support rings are fixedly connected to the base plate 1 through support legs. The function of the support rings is to support the outer ring of the one-way bearing 601 when the winding traction shaft 6 rotates counterclockwise, and to reduce the friction between the outer ring of the one-way bearing 601 and the inner ring by supporting the weight of the outer ring.

[0033] The working principle of this utility model is as follows: the woven bag of drawing material is placed above the feeding car 3, and then the feeding car 3 is pulled to the position above the feeding hopper 2 by rotating the winding traction shaft 6. The blade inside the sliding shell 201 is used to cut the woven bag so that the drawing material inside flows into the feeding hopper 2. The bottom of the feeding hopper 2 is provided with a reserved opening. The drawing material can flow into the pipe between the feeding pipe 9 and the blower 8 through the reserved opening. The drawing material is blown into the drawing machine through the feeding pipe 9 by starting the blower 8.

[0034] The two ends of the winding traction shaft 6 are used to wind up the traction rope 7. The one-way bearing 601 is located in the middle of the winding traction shaft 6. When it is necessary to pull the loading car 3 upwards towards the feed hopper 2 via the traction rope 7, the winding traction shaft 6 needs to be rotated clockwise. During this process, the traction rope 7 is wound up, and the loading car 3 is pulled by the same length. The one-way bearing 601 rotates accordingly. Since the one-way bearing 601 is meshed with the reciprocating wheel 602, when the one-way bearing 601 rotates, it drives the reciprocating wheel 602 to rotate. The transmission rod 60 on one side of the reciprocating wheel 602... 3. Driven by the reciprocating wheel 602, the transmission rod 603 reaches its highest point when the transmission pin is at the upper end of the rotating reciprocating wheel 602, and reaches its lowest point when the transmission pin is at the upper end of the rotating reciprocating wheel 602. Thus, the connecting rod 204 achieves vertical reciprocating motion through the transmission rod 603. The reciprocating plate 202 at the top of the connecting rod 204 reciprocates vertically inside the sliding shell 201, thereby driving the blade to reciprocate at the top of the feed hopper 2, thereby cutting the upcoming woven bag of filament material.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
