SUMMARY

This utility model, by setting a limiting component, allows the reciprocating slider to move along the reciprocating screw as the motor drives it to rotate, thus moving the air sweeping pipe back and forth. Simultaneously, the limiting hole moves along the trajectory of the limiting rod. The cooperation between the limiting hole and the limiting rod provides limiting assistance for the movement of the reciprocating slider, preventing it from tilting during the reciprocating movement of the air sweeping pipe and causing the cold air blown out by the air sweeping pipe to not be evenly swept onto the glass.

Detailed Implementation

[0019] 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.

[0020] like Figures 1 to 3 As shown, this utility model provides a quenching device for producing viewing window glass for washing machines, including a cooling box 1, a pushing platform 2, and a cold air device 3. The cooling box is distributed on the left and right sides. The left side of the pushing platform 2 is fixedly connected to the right side of the cooling box 1. The cold air device 3 is connected to the top and bottom sides of the cooling box 1. Two air sweeping pipes 4 are provided inside the cooling box 1. The outer sides of the air sweeping pipes 4 are connected to the output end of the cold air device 3 through ducts. The air sweeping pipes are distributed front and back, and the air outlets of the two air sweeping pipes face the center of the glass.

[0021] Reciprocating mechanisms 5 are fixedly connected to both the top and bottom sides of the back of the cooling box 1. (Reference) Figure 2 and Figure 3 The reciprocating mechanism 5 includes a motor 51, whose front side is fixedly connected to both sides of the back of the cooling box 1. A reciprocating lead screw 52 is provided on the outer side of the air sweeping pipe 4, with both sides of the reciprocating lead screw 52 extending to both sides of the front and back of the cooling box 1. That is, the two ends of the reciprocating lead screw are connected to the mounting grooves on the front and back side walls of the cooling box via bearings. The output end of the motor 51 is fixedly connected to the rear end of the reciprocating lead screw 52, ​​and the motor drives the reciprocating lead screw to rotate synchronously. A reciprocating slider 53 is threaded onto the surface of the reciprocating lead screw 52, ​​and the inner side of the reciprocating slider 53 is fixedly connected to the outer side of the air sweeping pipe 4. A limit component 6 is provided on the outer side of the front of the reciprocating slider 53. This configuration forms a "lead screw and nut" structure between the reciprocating lead screw and the reciprocating slider. The motor drives the reciprocating lead screw to rotate synchronously, and the reciprocating lead screw and the reciprocating slider are connected by rotation. With the assistance of the limit component, the forward and reverse rotation of the motor drives the reciprocating slider on the reciprocating lead screw to move back and forth.

[0022] As a technical optimization of this utility model, by setting a reciprocating mechanism 5, when the user needs the air sweeping pipe 4 to move back and forth, the motor 51 is started, which drives the reciprocating lead screw 52 to rotate synchronously, so that the reciprocating slider 53 moves along the reciprocating lead screw 52 under the action of the limit rod, driving the air sweeping pipe 4 to move back and forth in the cooling box 1, so that the air sweeping pipe 4 can evenly sweep the cold air blown out by the cold air device 3 onto the glass, thereby improving the user's ease of operation.

[0023] refer to Figure 2 and Figure 3The limiting component 6 includes a limiting hole 61, which is opened on the outer side of the front of the reciprocating slider 53. A limiting rod 62 is provided inside the limiting hole 61. The two sides of the limiting rod 62 are fixedly connected to the front and rear sides of the inner wall of the cooling box 1.

[0024] As a technical optimization of this utility model, by setting a limiting component 6, when the motor 51 drives the reciprocating screw 52 to rotate, the reciprocating slider 53 moves along the reciprocating screw 52, ​​and the sweeping pipe 4 moves back and forth, the limiting hole 61 moves along the limiting rod 62 at the same time. Then, through the cooperation of the limiting hole 61 and the limiting rod 62, the movement of the reciprocating slider 53 is limited and assisted, preventing the reciprocating slider 53 from tilting during the reciprocating movement of the sweeping pipe 4, which would cause the cold air blown out by the sweeping pipe 4 to not be evenly swept onto the glass, thereby improving the stability of the reciprocating slider 53 when it drives the sweeping pipe 4 to move.

[0025] refer to Figure 2 and Figure 3 The reciprocating slider 53 has a trapezoidal groove 7 on its inner side, and a trapezoidal block 8 is slidably connected to the inner wall of the trapezoidal groove 7. The inner side of the trapezoidal block 8 is fixedly connected to the outer side of the sweeping pipe 4. The sweeping pipe is arranged in a left-right distribution.

[0026] As a technical optimization of this utility model, by setting trapezoidal groove 7 and trapezoidal block 8, when connecting reciprocating slider 53 to air sweeping pipe 4, the user holds air sweeping pipe 4, aligns trapezoidal block 8 on air sweeping pipe 4 with trapezoidal groove 7 on reciprocating slider 53, and then inserts it, thereby connecting air sweeping pipe 4 to reciprocating slider 53. Then, reciprocating slider 53 can drive air sweeping pipe 4 to move, which makes it convenient to replace air sweeping pipe 4 when it is damaged after long-term use.

[0027] refer to Figure 1 and Figure 2 The cooling box 1 has mounting grooves 9 on both sides of the front and back. The inner wall of the mounting groove 9 is movably connected to the ball bearing 10. The two ends of the reciprocating screw 52 are movably connected to the inner wall of the ball bearing 10.

[0028] As a technical optimization of this utility model, by setting the mounting groove 9 and the roller bearing, during the process of the motor 51 driving the reciprocating screw 52 to rotate, the ball bearing 10 in the mounting groove 9 rotates with the reciprocating rotation. Subsequently, through the ball bearing 10 and the mounting groove 9, an efficient, stable and smooth rotation axis point is provided for the reciprocating screw 52 on the cooling box 1, thereby improving the stability and smoothness of the reciprocating screw 52 during rotation.

[0029] refer to Figure 3 A linear bearing 11 is movably connected to the inner wall of the limiting hole 61, and the inner wall of the linear bearing 11 is movably connected to the surface of the limiting rod 62.

[0030] As a technical optimization of this utility model, by setting a linear bearing 11, during the process of the limiting hole 61 moving along the limiting rod 62 with the reciprocating slider 53, the linear bearing 11 drives the limiting hole 61 to contact the limiting rod 62, and the steel ball inside it will rotate against the surface of the limiting rod 62 when the reciprocating slider 53 moves, thereby reducing the frictional resistance between the limiting hole 61 and the limiting rod 62, reducing wear, and thus improving the service life of the limiting hole 61 and the limiting rod 62.

[0031] refer to Figure 3 Knurled bolts 12 are provided on both sides of the reciprocating slider 53. One end of the knurled bolt 12 passes through the inner wall of the trapezoidal groove 7 and is threadedly connected to the inner wall of the trapezoidal block 8.

[0032] As a technical optimization of this utility model, by setting a knurled bolt 12, after the trapezoidal block 8 is inserted into the trapezoidal groove 7, the knurled bolt 12 is then inserted into the reciprocating slider 53, through the trapezoidal groove 7, and then screwed in until it is screwed into the trapezoidal block 8, so that the trapezoidal block 8 is fixed in the trapezoidal groove 7, thereby making the air sweeping pipe 4 and the reciprocating slider 53 firmly connected.

[0033] The working principle and usage process of this utility model are as follows: After the glass has completed the quenching process, when it needs to be cooled quickly, the quenched glass is placed on the pusher table 2, and the glass is pushed into the cooling chamber 1 by the pusher table 2. Then, the cold air device 3 is started first, so that cold air is blown out from its output end. Then, the cold air is delivered through the duct and blown out from the sweeping pipe 4. At this time, the motor 51 is started, which drives the reciprocating screw 52 to rotate, so that the reciprocating slider 53 moves along the reciprocating screw 52 (equivalent to the screw and nut structure), which drives the sweeping pipe 4 to cool down. The glass moves back and forth inside the box 1. At the same time, the limiting hole 61 moves along the limiting rod 62 with the reciprocating slider 53, which limits the movement of the reciprocating slider 53. This allows the air sweeping pipe 4 to evenly sweep the cold air blown by the cold air device 3 onto the glass, and to cool both sides of the glass evenly until the glass is cooled down. This prevents the temperature gradient caused by fixed-point air blowing during the glass cooling process, which could lead to micro-cracks or spontaneous breakage inside the glass and cause damage. Thus, it has the advantage of uniform air sweeping cooling.

[0034] In summary, this quenching device for producing the viewing window glass of a washing machine, by setting up a sweeping air pipe 4, after the quenched glass is pushed into the cooling box 1 by the pusher table 2, when the cold air device 3 is activated, the reciprocating mechanism 5 pushes the sweeping air pipe 4 back and forth, so that the cold air blown by the cold air device 3 is evenly swept onto the glass. This solves the problem that although the glass can be blown by the wind on both sides at the same time, the air duct is fixed and can only blow air at a fixed point, and cannot circulate and move evenly to blow air onto the glass. This can lead to temperature steps during the cooling process of the glass, causing micro-cracks or spontaneous breakage inside the glass.
