Technical Field

[0001] The invention relates to the technical field of acrylic plate processing equipment, in particular to a bending machine for producing acrylic plates and a bending method thereof. Background Art

[0002] Acrylic sheet, also known as specially treated plexiglass, is a replacement product for plexiglass. Light boxes made of acrylic have the characteristics of good light transmittance, pure color, rich colors, beautiful and smooth appearance, taking into account both day and night effects, long service life, and no impact on use.

[0003] When bending acrylic sheets, the surface of the acrylic sheets needs to be heated to reduce the breakage rate of the acrylic sheets. However, in order to improve processing efficiency, the bending machine of the production line has a temperature much higher than the processing temperature. Excessive temperature will cause the surface of the acrylic sheet to melt, while the bottom has not been heated. At this time, if the sheet is bent, creases will appear on the harder part of the bottom. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a bending machine for acrylic plate production, comprising a support mechanism, the support mechanism also includes a mounting plate, the bottom of the mounting plate is fixedly connected to a support rod, and one end of the support rod away from the mounting plate is fixedly connected to a pressure frame;

[0005] The heating bending mechanism includes an electric telescopic rod fixedly connected to the bottom of the mounting plate, an end of the electric telescopic rod away from the mounting plate is fixedly connected to an L-shaped pressure plate, a sliding frame is fixedly connected to the side wall of the L-shaped pressure plate, an end of the sliding frame away from the L-shaped pressure plate is slidably connected to a heating plate, and a heating rod is fixedly connected to the bottom of the heating plate;

[0007] Preferably, the support mechanism also includes an inclined panel fixedly connected to the top of the pressure frame, the bottom of the mounting plate is fixedly connected to a limiting frame 1, a roller 1 is rotatably connected to the inner wall of the limiting frame 1, and a heat-absorbing cloth is sleeved on the outer wall of the roller 1.

[0008] Preferably, the supporting mechanism also includes a limiting frame 2 fixedly connected to the bottom of the mounting plate, a rotating cylinder is rotatably connected to the inner wall of the limiting frame 2, a roller 2 is rotatably connected to the inner wall of the through hole of the limiting frame 2, a reserved groove is provided on the top of the pressure frame, an acrylic plate is placed on the top of the pressure frame, and a baffle is fixedly connected to the inner wall of the support rod. In order to solve the problem that high-power heat may cause melting of the acrylic surface, a supporting mechanism is provided inside the device. Before using the device, the acrylic plate to be processed is inserted into the device through the gap formed between the support rod and the pressure frame to form a Figure 1 The state shown is shown, and the power of the electric telescopic rod and the heating rod is turned on. As the electric telescopic rod drives the heating plate and the heating rod to move downward through the L-shaped pressure plate and the sliding frame, the electric telescopic rod first contacts the inner wall of the heat absorbing cloth and forces the heat absorbing cloth to deform. As the heat absorbing cloth contacts the surface of the acrylic plate, the heat absorbing cloth absorbs the heat emitted by the heating rod and forces the bending part of the acrylic plate to soften. At the same time, as the heating plate contacts the acrylic surface, the sliding frame will continue to move downward along the inner wall of the heating plate and force the bottom of the L-shaped pressure plate to contact the top of the acrylic plate. As the L-shaped pressure plate continues to press downward, the bending of the acrylic plate will be completed. Through the application of the above components, direct contact between the heating rod and the acrylic plate can be avoided, which will result in uneven heating of the acrylic plate and melting of the surface of the acrylic plate.

Utilizing the characteristics of the up and down movement of the L-shaped pressure plate, a control rod and an inclined groove are arranged inside the equipment, and one end of the inclined groove is a vertical surface and the other end is an inclined surface. When the control rod moves downward, the rotating plate contacts the acrylic plate, rotates along the inner wall of the inclined groove and fits with the inclined surface of the inclined groove, and at this time, the second roller is not controlled by the control rod; when the control rod moves upward, the rotating plate contacts the inner wall of the acrylic plate and contacts the vertical surface of the inclined groove, forcing the second roller to rotate, and the rotation of the second roller will drive the heat absorbing cloth to rotate, causing the heat absorbing cloth to move. Through the application of the above-mentioned components, the heat absorbing cloth can be converted after the equipment completes a single processing, thereby avoiding long-term contact between the cloth and the second roller, which may cause damage to the heat absorbing cloth.

The present invention utilizes an acrylic plate to present an L-shape after processing, and a discharge plate is arranged inside the equipment. The L-shaped pressure plate moves up, and the discharge plate is driven to move up by the pushing frame. In this process, the top of the discharge plate will drive the bottom of the acrylic plate to move up, thereby completing the autonomous demolding of the equipment.

[0012] Preferably, the cooling mechanism also includes a roller rotatably connected to the end of the sliding square rod away from the cooling bag, a water inlet check valve is connected through the side wall of the cooling bag, and a water outlet check valve is connected through the side wall of the cooling bag. Taking advantage of the fact that the bending position is mostly arc-shaped, a contact rod and a cooling bag are arranged inside the device. When the device is bent, the roller contacts the inclined surface of the inclined panel and forces the sliding square rod to push the cooling bag to contact the bending position of the acrylic plate when the L-shaped pressure plate moves downward, thereby quickly cooling the bending position to avoid rebound of the bending position after bending due to the toughness of the acrylic itself, resulting in a deviation in the bending angle.

[0013] A bending machine for producing acrylic sheets and a bending method thereof, comprising the following steps:

[0014] S1: Before using the present invention, the acrylic plate to be processed is inserted into the equipment through the gap formed between the support rod and the pressure frame, and the power supply of the electric telescopic rod and the heating rod is turned on;

[0015] S2: As the electric telescopic rod drives the heating plate and the heating rod to move downward through the L-shaped pressure plate and the sliding frame, the electric telescopic rod first contacts the inner wall of the heat absorbing cloth and forces the heat absorbing cloth to deform;

[0016] S3: As the heat-absorbing cloth contacts the surface of the acrylic plate, it absorbs the heat emitted by the heating rod and forces the bending part of the acrylic plate to soften. At the same time, as the heating plate contacts the acrylic surface, the sliding frame will continue to move down along the inner wall of the heating plate and force the bottom of the L-shaped pressure plate to contact the top of the acrylic plate. As the L-shaped pressure plate continues to press down, the bending of the acrylic plate will be completed.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem that high-power heat may cause the acrylic surface to melt. A support mechanism is provided inside the device. Before using the device, the acrylic plate to be processed is inserted into the device through the gap formed between the support rod and the pressure frame to form a Figure 1The state shown is shown, and the power of the electric telescopic rod and the heating rod is turned on. As the electric telescopic rod drives the heating plate and the heating rod to move downward through the L-shaped pressure plate and the sliding frame, the electric telescopic rod first contacts the inner wall of the heat absorbing cloth and forces the heat absorbing cloth to deform. As the heat absorbing cloth contacts the surface of the acrylic plate, the heat absorbing cloth absorbs the heat emitted by the heating rod and forces the bending part of the acrylic plate to soften. At the same time, as the heating plate contacts the acrylic surface, the sliding frame will continue to move downward along the inner wall of the heating plate and force the bottom of the L-shaped pressure plate to contact the top of the acrylic plate. As the L-shaped pressure plate continues to press downward, the bending of the acrylic plate will be completed. Through the application of the above components, direct contact between the heating rod and the acrylic plate can be avoided, which will result in uneven heating of the acrylic plate and melting of the surface of the acrylic plate.

[0019] (2) The present invention utilizes the characteristic of the L-shaped pressure plate moving up and down, and is provided with a control rod and an inclined groove inside the device, wherein one end of the inclined groove is a vertical surface and the other end is an inclined surface. When the control rod moves downward, the rotating plate contacts the acrylic plate, rotates along the inner wall of the inclined groove and fits with the inclined surface of the inclined groove. At this time, the second roller is not controlled by the control rod; when the control rod moves upward, the rotating plate contacts the inner wall of the acrylic plate and contacts the vertical surface of the inclined groove, forcing the second roller to rotate, and the rotation of the second roller will drive the heat absorbing cloth to rotate, causing the heat absorbing cloth to move. Through the application of the above components, the heat absorbing cloth can be converted after the equipment completes a single processing, thereby avoiding long-term contact between the cloth and the second roller, which may cause damage to the heat absorbing cloth.

[0020] (3) The present invention utilizes the characteristic that the bending position is mostly arc-shaped, and a contact rod and a cooling bag are arranged inside the equipment. When the equipment is bending, the roller contacts the inclined surface of the inclined plate, and forces the sliding square rod to push the cooling bag to contact the bending position of the acrylic plate when the L-shaped pressure plate moves down, so as to quickly cool down the bending position, thereby avoiding the rebound of the bending position and the deviation of the bending angle due to the toughness of the acrylic itself after bending. In addition, the present invention utilizes the fact that the acrylic plate is L-shaped after processing, and an outfeed plate is arranged inside the equipment. The L-shaped pressure plate moves up, and the outfeed plate is driven up by the pushing frame. In this process, the top of the outfeed plate will drive the bottom of the acrylic plate to move up, thereby completing the autonomous demolding of the equipment.

[0021] (4) The present invention utilizes the force of the cooling bag to expand and contract after it contacts the bending position, and a water inlet check valve and a water outlet check valve are provided inside the device. After the cooling bag is cooled, as the electric telescopic rod continues to advance, the cooling bag is clamped by the vertical surface of the mounting plate and the L-shaped pressure plate, which will force the liquid inside the cooling bag to be discharged outward through the water outlet check valve. After the equipment completes the processing, the cooling bag is reset by the pressure spring and the extrusion spring, so that the external coolant enters the cooling bag through the water inlet check valve, thereby realizing self-replenishment of the coolant.
