Description

Technical Field

[0001] The utility model relates to the field of 3D printing, in particular to a wire blocking device for a winding machine. Background Art

[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, using adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. Among them, FDM is the most widely used technology. Currently, plastic materials are used as raw materials for wire, generally in the form of round wire. During the printing operation, the wire enters the nozzle of the printer, is quickly heated and melted, and then ejected from the nozzle in a stack. The current main packaging and storage method for wire is to wind the wire on a dedicated I-shaped reel to form a wire coil. Generally, the total length of each kilogram of wire winding reaches more than 300 meters. When winding, the wire passes through a dedicated wire guide and then is wound onto the I-spool. Since the I-spool needs to move according to the wire position during the winding process, the wire guide is generally far away from the loading position to prevent it from colliding with the left and right sides of the I-spool. Due to the long distance, the wire will vibrate and deflect between the wire guide outlet and the I-spool loading position during the winding process. This vibration and deviation are transmitted to the wire arrangement position, which will have a certain impact on the wire arrangement accuracy. Because the wire is too long, as the winding length accumulates, this accuracy error accumulates, resulting in uneven wire arrangement, especially the last turn of each layer winding close to the disk surface. After the last turn is wound, the wire will be superimposed to start the second layer of winding, exacerbating the occurrence of irregular wire slippage. In severe cases, problems such as stacking and pressing of the upper and lower layers may even occur. These problems affect the appearance on the one hand, and on the other hand, they will cause the wire winding and unwinding action to be not smooth in actual use, and sometimes the wire will even be stuck, ultimately leading to the failure of the 3D printing operation. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a wire blocking device for a winding machine, which can replace the existing wire guide and improve the wire arrangement quality.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a wire blocking device for a winding machine, wherein the wire blocking device for a winding machine is installed on the base of the winding machine, and is located between the wire outlet frame and the I-shaped pulley for winding.

[0005] In a preferred embodiment of the present invention, the angle between the inner baffle and the outer baffle is 90° to 180°.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0022] See also Figures 1 to 6 , the embodiments of the present utility model include:

[0023] A wire-blocking device for a winding machine, which is installed on the base of a winding machine 5 and is located between the wire outlet frame 4 of the wire 8 and the I-shaped wheel 6 installed on the winding machine 5. The wire-blocking device for a winding machine includes: a wire-blocking wheel 1, a wire-blocking motor 3 and a lifting bracket 2. The wire-blocking motor 3 is fixed on the lifting bracket 2, and the wire-blocking wheel 1 is installed on the power output shaft of the wire-blocking motor 3. The wire-blocking wheel 1 includes a base plate 102, an inner baffle 103 and an outer baffle 104. The center position of the base plate 102 is provided with a mounting hole 101 that matches the power output shaft of the wire-blocking motor 3. The inner baffle 103 and the outer baffle 104 are staggered on the base plate 101. The vertical distance between the inner side surface of the outer baffle 104 and the inner side surface of the inner baffle 103 is slightly larger than the wire diameter of the wire 8.

[0024] The angle between the inner baffle 103 and the outer baffle 104 is 90° to 180°. In practice, it is typically 150°. A clamping plate 105 is also provided between the outer baffle 104 and the inner baffle 103. The angle between the clamping plate 105 and the inner and outer baffles 103 and 104 is equal to 75°. This ensures sufficient clearance between the clamping plate 105 and the inner and outer baffles 103 and 104. The clamping plate 105 consists of an inner and outer plate. The inner side of the inner plate is flush with the inner side of the inner baffle 103, and the inner side of the outer plate is flush with the inner side of the outer baffle 104. In this way, the various positions are staggered with each other, so that when the winding position reaches the inner limit position of the I-spool 6, the wire clamping plate 105 and the corresponding inner baffle 104 can rotate away, and when reaching the outer limit position, the wire clamping plate and the outer baffle 104 can rotate away. When in the middle position, the wire outlet path is restricted by the wire clamping plate 105.

[0025] The lifting bracket includes a lifting frame 201, a transmission screw 204, a positioning optical axis 205, a lifting platform 206 and a driving motor 202. The lifting frame 201 is fixed on the base 7 of the winding machine 5. The transmission screw 204 and the positioning optical axis 205 are both vertically installed in the lifting frame 201. The lifting platform 206 is provided with an internal threaded hole matching the rod of the transmission screw 204 and a limiting hole matching the rod of the positioning optical axis 205. The transmission screw 204 and the positioning optical axis 205 pass through the corresponding internal threaded hole and limiting hole respectively. The lifting platform 206 is installed in the lifting frame 201, the driving motor 202 is fixed on the base 7 of the winding machine 5, the transmission screw 204 is installed with a synchronous wheel 203 at the bottom, the power output end of the driving motor 202 is installed with a driving wheel, the synchronous wheel 203 is connected to the driving wheel by a synchronous belt, the wire blocking motor 3 is installed on the lifting platform 206, the driving motor 202 can drive the transmission screw 204 to rotate, and drive the lifting platform 206 to move vertically up and down along the direction determined by the positioning optical axis 205. In this way, the position of the lifting platform 206 can be adjusted according to the needs of actual production, so that the wire blocking wheel 1 can be as close as possible to the wire loading position of the I-shaped wheel 6, thereby improving the winding stability of the I-shaped wheel 6. There are two positioning optical axes 205, which are symmetrically arranged on both sides of the transmission screw 204. In this way, when the lifting platform 206 moves, the limiting holes on both sides act simultaneously to improve the overall stability.

[0026] The lifting platform 206 extends in the direction of advancement of the wire 8, partially exceeding the range of the lifting frame 201. The portion of the lifting platform 206 that exceeds the lifting frame 206 is installed with a motor mounting plate 207, and the wire blocking motor 3 is fixed on the motor mounting plate 207. This arrangement can reduce the interference of the lifting frame 201 on the movement of the wire blocking wheel 1, increase the activity space of the wire blocking wheel 1, and facilitate the wire blocking wheel 1 to approach the wire loading position on the I-shaped reel 6.

[0027] The lifting platform 206 is also provided with a chute, which is clamped on the frame edge of the lifting frame 201. The chute structure can further stabilize the lifting platform 206, reducing the impact of the wire blocking motor 3 and the wire blocking wheel 1 being installed on one side on the movement of the lifting platform 206.

[0028] The working principle of this utility model is as follows:

[0029] First, if Figure 4Before the winding machine is started, the outer baffle 104 area of ​​the wire wheel 1 is in the working position, close to the left side of the I-shaped wheel 6, and the wire 8 is close to the left side of the wheel; the first layer of winding begins, the main shaft of the winding machine 5 starts, and the I-shaped wheel 6 starts to move horizontally while rotating. For each rotation, the horizontal movement distance is x, where x is the diameter of the wire 8, and the first turn of winding is completed.

[0030] Then, if Figure 5 As shown in , when the winding reaches the second turn, the wire wheel 1 is driven by the wire motor 3 to rotate until the wire clamping plate 105 reaches the working position, and the wire clamping plate 105 clamps the wire 8 in the middle to limit the left and right swing of the wire 8;

[0031] Finally, if Figure 6 As shown in , the number of winding turns continues to increase. When the winding reaches the last turn, the wire blocking motor 3 drives the wire blocking wheel 1 to rotate until the inner baffle 103 reaches the working position, and the wire 8 is pressed against the right side of the I-shaped wheel disc 6.

[0032] The above steps are repeated until the wire arrangement is complete. In this way, the distance that the wire 8 needs to travel after it leaves the wire retaining wheel 1 and enters the loading position of the I-shaped reel 6 is significantly shorter than that of a traditional wire guide mechanism, significantly reducing the impact of wire vibration and deviation on the wire arrangement, improving the regularity of the winding, and thus reducing operational problems caused by wire winding and unwinding failures during 3D printing.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
