Description

Technical Field

[0001] The present invention relates to the technical field of thermoplastic processing of glass panels, and more specifically, to a bending device for a washing machine glass panel. Background Art

[0002] The bending device for a washing machine glass panel is mainly used for processing glass panels of household appliances such as washing machines. In order to improve the strength, plexiglass is used for the washing machine glass panel. Plexiglass is a common name, abbreviated as PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound polymerized from methyl methacrylate. It is an important thermoplastic plastic developed earlier. Plexiglass is divided into four types: colorless transparent, colored transparent, pearlescent, and embossed plexiglass, enabling it to meet specific shape and design requirements. It is necessary to feed the glass panel to be processed into the heating chamber of the device, and heat the glass through electric heating rollers or electric heating plates until it reaches the softening point and undergoes bending treatment. The glass panel not only has the required appearance form, but also enhances its structural strength and impact resistance, thereby improving the overall quality and durability of the product.

[0003] In the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN220129507U discloses a glass panel bending device. Through the provided conversion device, the end of the limiting component is moved out of the limiting groove, so that the rotating column is in a rotatable state. The rotating column drives the pressing block to rotate, so that the pressing blocks of the corresponding structure face downward. Through the mutual cooperation of the four pressing blocks and the base device, the device can bend plexiglass into various structures. However, the following problems still exist when using this technology:

[0004] The washing machine glass panel is mainly made of thermoplastic plastic. When this thermoplastic plastic is heated and bent, although it can provide a vertical bending force to make the thermoplastic plastic of the washing machine glass panel bend vertically along the specified arc, the thermoplastic plastic of the washing machine glass panel not only has a vertical bending surface, but also has bending surfaces at each corner position, and also has bending requirements for both end surfaces and two inclined surfaces. This leads to the need for the washing machine glass panel to be vertically stressed and bent, then fixed, then bent at the positions of both end surfaces, and then fixed again, and then continue to be bent at the positions of the two inclined surfaces. Moreover, the position needs to be changed each time, resulting in uneven stress during bending forming, making it difficult to apply the specified bending forming force and difficult to synchronously bend and form the multiple corner positions, both end surface positions, and two inclined surface positions of the thermoplastic plastic of the washing machine glass panel according to the specified bending force, resulting in a low efficiency of bending the thermoplastic plastic of the washing machine glass panel into a curved surface. Therefore, a bending device for a washing machine glass panel is needed. Summary of the Invention

The side surface of the limiting support plate 40 is processed with a rounded corner.

[0038] The working principle of the glass panel bending device for the washing machine of the present invention is as follows:

[0039] First, when the present invention is installed and fixed, drilling operations are carried out according to the hole positions of the support plate 16, and then expansion bolts are inserted into the hole positions of the support plate 16, so that the support plate 16 can be fixed at the installation position. The support plate 16 supports the groove column 1, and at the same time the support plate 16 supports the socket frame 2. The socket frame 2 supports the connecting bar 5, and at the same time the socket frame 2 supports the vertical electric cylinder 3. The groove column 1 supports the arc heating plate 10. Then, the preheated washing machine glass panel 11 is placed on the inner wall of the arc heating plate 10, and the outer wall of the washing machine glass panel 11 is limited by the limiting block 13. The washing machine glass panel 11 is mainly made of plexiglass, and the chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound polymerized from methyl methacrylate. The washing machine glass panel 11 is a thermoplastic plastic.

[0040] Secondly, when the present invention performs vertical corner synchronous equal-force bending, the vertical electric cylinder 3 is started through the controller 15. The output end of the vertical electric cylinder 3 moves downward along the inner wall of the socket frame 2. At the same time, the output end of the vertical electric cylinder 3 drives the vertical pressure sensor 4 to move downward. The vertical pressure sensor 4 causes the connecting bar 5 to move downward, and the connecting bar 5 drives the arc bending plate 6 to move downward. The arc bending plate 6 can be pressed against the upper surface of the washing machine glass panel 11, so that the washing machine glass panel 11 forms a vertical arc bending between the arc heating plate 10 and the arc bending plate 6.

[0041] At the same time, the arc bending plate 6 drives a plurality of support columns 7 to move downward. The support columns 7 drive the inclined block 8 to move downward obliquely. The inclined block 8 drives the corner bending columns 9. The plurality of corner bending columns 9 are respectively pressed against a plurality of corner positions of the washing machine glass panel 11. The corners of the washing machine glass panel 11 are pressed against the corner bending block 12 to undergo force-induced bending deformation. At the same time, the plurality of resistance heating rods 14 continuously heat and soften the washing machine glass panel 11. In this way, not only can the vertical bending of the washing machine glass panel 11 be achieved, but also the synchronous bending of a plurality of corner positions of the washing machine glass panel 11 can be carried out simultaneously. When the pressure value sensed by the vertical pressure sensor 4 is the same as the pressure value set by the controller 15, the vertical electric cylinder 3 is closed through the controller 15, so that the arc heating plate 10 can be bent and formed according to the specified pressure.

[0042] Meanwhile, when the present invention performs synchronous equal-force bending at both ends, the controller 15 starts the side electric cylinder 17 at the same time. The side electric cylinder 17 pushes the lateral pressure sensor 18 downward. The lateral pressure sensor 18 causes the connecting frame 19 to move downward, and the connecting frame 19 can drive the V-shaped guide rail 20 to move downward. The V-shaped guide rail 20 drives the two sliding shafts 21 to approach each other. One sliding shaft 21 moves to the right, and the other sliding shaft 21 moves to the left. The sliding shafts 21 drive the two limit rings 22 to move to the right, and the limit rings 22 slide to the right along the V-shaped guide rail 20. At the same time, the sliding shafts 21 drive the socket slider 23 to move to the right. The socket slider 23 moves to the right along the inner wall of the guide frame 25 and also moves to the right along the outer wall of the guide rod 24. At the same time, the socket slider 23 causes the linkage frame 26 to move to the right. The linkage frame 26 drives the support frame 27 to move to the right. The support frame 27 causes the lateral bending plate 28 to move to the right. The lateral bending plate 28 presses against the left end face of the bent washing machine glass panel 11, and the other lateral bending plate 28 presses against the right side face of the bent washing machine glass panel 11. When the pressure value sensed by the lateral pressure sensor 18 is the same as the pressure value set by the controller 15, the controller 15 closes the side electric cylinder 17. The two lateral bending plates 28 can synchronously bend the two end faces of the washing machine glass panel 11 into an arc surface according to the specified extrusion force.

[0043] Finally, when the present invention performs synchronous equal-force bending of two inclined surfaces, the controller 15 starts the extrusion electric cylinder 29 at the same time. The extrusion electric cylinder 29 pushes the inclined pressure sensor 30 downward. The inclined pressure sensor 30 drives the guide disk 31 to move downward synchronously. The guide disk 31 drives the two linkage rods 32 to move downward synchronously. The two linkage rods 32 respectively drive the two sliding frames 33 to move downward synchronously. The sliding frames 33 drive the chute shaft 34 to move downward, and the chute shaft 34 drives the inclined chute column 35 to move downward obliquely. The inclined chute column 35 moves downward obliquely along the inner wall of the socket block 36.

[0044] The chute shaft 34 will move to the left along the inner wall of the sliding frame 33, and at the same time, the other chute shaft 34 moves to the right. At the same time, the arc heating plate 10 supports the support plate 37, and the support plate 37 supports the socket block 36, ensuring that the inclined chute column 35 drives the pressing plate 38 to be able to move downward obliquely. The pressing plate 38 drives the inclined bending plate 39 to move downward obliquely. The inclined bending plate 39 drives the limit support plate 40 to move downward obliquely. The limit support plate 40 can be inserted into the inclined surface gap between the arc heating plate 10 and the washing machine glass panel 11. At the same time, the inclined bending plate 39 presses against one inclined surface of the washing machine glass panel 11, and the other inclined bending plate 39 presses against the other inclined surface of the washing machine glass panel 11. When the pressure value sensed by the inclined pressure sensor 30 is the same as the pressure value set by the controller 15, the controller 15 closes the extrusion electric cylinder 29. The two extrusion electric cylinders 29 can press against the two inclined surfaces of the washing machine glass panel 11 according to the specified extrusion force, so as to synchronously perform the bending forming operation on the two inclined surfaces of the washing machine glass panel 11.
