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.

[0020] Example: Figures 1-4As shown, this utility model provides a technical solution: a quick-change device for glass fiber drawing dies, including a body 1, a die body 31, and a placement box 2. A fiber outlet 3 is provided at the front end of the body 1 near the center. The inner wall of the fiber outlet 3 is mirror-polished to reduce frictional resistance during glass fiber drawing. A placement groove 22 is provided at the front end of the body 1 below the fiber outlet 3.

The placement groove 22 is slidably inserted at the front end of the body 1 near the fiber outlet 3. A gear 4 is rotatably connected at the front end of the body 1 near the fiber outlet 3. The gear 4 has a circular groove in its center, which does not affect the normal fiber output effect. Mounting blocks 32 are symmetrically fixedly connected to the outer ring of the die body 31 near the center. A limiting hole 33 is provided at the center of the side of the mounting block 32 away from the die body 31. A support plate 5 is symmetrically fixedly connected to the gear 4. A positioning shaft 51 is slidably inserted inside the support plate 5, and the positioning shaft 51 is adapted to the limiting hole 33.

The devices have not been structurally modified in this paper. Therefore, those skilled in the art are familiar with their working principle based on their professional knowledge and can apply it skillfully. Therefore, this paper will not elaborate on it in detail. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposal of the processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0021] A mounting plate 23 is fixedly connected to the front end of the box 2 near the center of the top. A magnetic block 24 is provided at the center of the end of the mounting plate 23 near the body 1.

[0022] By adopting the above technical solution, magnetic block 24 is set up to work with magnetic block 26 to achieve the adsorption effect and prevent the placement box 2 from accidentally sliding out. When the two magnets approach each other, the electromagnetic field between them changes, resulting in the exchange of virtual photons. One magnet emits virtual photons and the other magnet absorbs them. Through this quantum state transfer, the interaction force between the magnets is transmitted, so that the two magnets attract each other.

[0023] An inner groove 25 is provided at the front end of the body 1 and at the center of the top of the placement groove 22, and a magnetic block 26 is provided at the front end of the body 1 and at the inner groove 25.

[0024] By adopting the above technical solution, magnetic block 26 corresponds to magnetic block 24, and the two work together to further enhance the fixing effect of the placement box 2.

[0025] Gear 2 42 is rotatably connected to the front end of the machine body 1 near gear 1 4, and gear 2 42 meshes with gear 1 4. Motor 43 is provided at the front end of the machine body 1 near gear 2 42, and the output end of motor 43 is fixedly connected to gear 2 42.

[0026] By adopting the above technical solution, the starting motor 43 is operated, thereby causing the fixedly connected gear 42 to rotate.

[0027] A grooved wheel 44 is symmetrically rotatably connected to the front end of the body 1 and near the support plate 5. A cam 45 is fixedly connected to the front end of the grooved wheel 44. Two sets of auxiliary shafts 41 are symmetrically fixedly connected to the front end of the gear 4 and near the outer ring, and the auxiliary shafts 41 cooperate with the grooved wheel 44.

[0028] By adopting the above technical solution, the auxiliary shaft 41 located at the front end of gear 4 can be inserted into the groove of the grooved wheel 44 after rotation, which can drive the grooved wheel 44 to rotate.

[0029] An L-shaped rod 46 is slidably inserted inside the support plate 5, and the other end of the L-shaped rod 46 is fixedly connected to the positioning shaft 51. An auxiliary wheel 47 is provided on the side of the L-shaped rod 46 near the cam 45, and the auxiliary wheel 47 cooperates with the cam 45.

[0030] By adopting the above technical solution, the outer ring of the auxiliary wheel 47 is made of high wear-resistant rubber material. Under the drive of the cam 45, the L-shaped rod 46 can drive the positioning shaft 51 to perform telescopic movement.

[0031] A limiting plate 52 is fixedly connected to the outer ring of the positioning shaft 51 near one side. A spring 53 is fixedly connected to the side end of the limiting plate 52 and sleeved on the outer ring of the positioning shaft 51. The other end of the spring 53 is fixedly connected to the side end of the support plate 5.

[0032] By adopting the above technical solution, the diameter of the limiting plate 52 is larger than the diameter of the guide hole on the support plate 5, and the preload provided by the spring 53 can keep the positioning shaft 51 in an extended state when not in operation, which is convenient for it to cooperate with the limiting hole 33 of the mold body 31.

[0033] A pull ring 21 is fixedly connected at the center of the front end of the placement box 2.

[0034] By adopting the above technical solution, the pull ring 21 is made of stainless steel and the surface is treated with anti-slip material, making it easy for operators to pull and place the box 2.

[0035] Working principle: When using this device, a spare or other type of mold body 31 can be placed inside. When needed, the placement box 2 can be pulled out from the placement groove 22 by the pull ring 21, making it easy to install the spare mold at the wire outlet 3. By resetting and moving the placement box 2, and cooperating with the magnetic block 1 24 and magnetic block 26, the placement box 2 can be limited to prevent it from accidentally sliding out of the placement groove 22. This achieves the effect of storing the mold body 31, making it easy to retrieve quickly.

[0036] When replacing the mold body 31, the working motor 43 (the speed of the motor 43 is adjusted according to the actual use) causes the fixedly connected gear 42 to rotate, which in turn causes the meshing gear 4 to rotate, driving the two sets of auxiliary shafts 41 to rotate. This, in turn, drives the mating grooved wheel 44 and cam 45 to rotate. Then, under the action of the auxiliary wheel 47, the positioning shaft 51 can move horizontally and stretch the spring 53, thereby releasing the limiting work on the mold body 31. After replacing the mold body 31 with a brand new one, the motor 43 can be started in reverse, thus achieving the effect of quickly replacing the mold body 31 and improving the convenience of replacing and disassembling the mold body 31 for users.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
