Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0026] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0027] like Figures 1 to 6 As shown, the acrylic hot bending machine includes a housing 1, a cooling device 8, a heating tube 7, and a radiator 17. The top end face of the housing 1 is provided with a crystal sticker 12 and a control panel 9. The side wall end face of the housing 1 is provided with a boat-shaped switch socket 13. The housing 1 is a rectangular shell. The control panel 9 can display and adjust the heat, which is convenient for precise temperature control. Multiple end faces of the housing 1 are respectively provided with second heat dissipation holes 102 or first heat dissipation holes 101, which cooperate with the internal radiator 17 to dissipate heat, effectively reduce the internal temperature, and extend the service life. This is common knowledge in the field and will not be described in detail here.

[0028] A measuring component is slidably connected to one end face of the outer shell 1. The acrylic sheet to be processed is accurately positioned and fixed according to the required size by the measuring component before subsequent processing is carried out. The processing accuracy is high and the production efficiency is improved.

[0029] The measuring component includes a pair of scales 4 and a positioning bracket 3. The pair of scales 4 are fixedly connected to a pair of opposite end faces of the housing 1. The scales 4 are provided with graduations, which can be used to confirm the size of the product to be processed as needed.

[0030] The scale 4 is located between a pair of limiting plates 301 and fixing plates 302, and the positioning bracket 3 is slidably connected to the top end face of the housing 1. Specifically, after confirming the size of the product to be processed, the limiting plates 301 and fixing plates 302 are controlled to slide on the scale 4 to the target size, and the product is placed under the limiting plates 301 to proceed to the next process.

[0031] like Figures 1 to 2 As shown, the limiting plate 301 is L-shaped to prevent the acrylic sheet from sliding and shifting during processing, ensuring processing accuracy. Both the limiting plate 301 and the fixing plate 302 have a first threaded hole, and a screw 5 is threaded into the first threaded hole. The screw 5 passes through the first threaded hole and the guide rail groove 2, and slides in the guide rail groove 2. In use, by loosening the screw 5 upwards, the screw 5 can drive the limiting plate 301 and the fixing plate 302 to slide on the scale 4, thereby controlling the limiting plate 301 and the fixing plate 302 to adjust the distance between the fixing plate 302 and the heating tube 7 according to the processing size of the acrylic sheet, so as to carry out precise processing and avoid the occurrence of defective products due to non-compliant dimensions.

[0032] The limiting plate 301 and the fixing plate 302 are located on a pair of opposite end faces of the scale 4. That is, the middle end face of the limiting plate 301 and the fixing plate 302 clamps the scale 4 and fixes the scale 4, so as to facilitate the control of the limiting plate 301 and the fixing plate 302 sliding on the scale 4.

[0033] A pair of guide rail grooves 2 are provided on the top end face of the outer casing 1. The guide rail grooves 2 are located near the end face of the scale 4. The limiting plate 301 and the fixing plate 302 pass through the guide rail grooves 2 and fit with the scale 4, thereby driving the limiting plate 301 and the fixing plate 302 to slide on the scale 4 and the guide rail grooves 2. The projection of the top end face of the screw 5 on the horizontal plane is greater than the projection of the guide rail groove 2 on the horizontal plane, that is, the diameter of the top end face of the screw 5 is greater than the width of the guide rail groove 2, to prevent it from falling off during the adjustment process.

[0034] The outer casing 1 has a second groove 701 on one end face of the scale 4. A support plate 15 is integrally formed on the bottom end face of the outer casing 1 at the second groove 701. A limit frame 6 is snapped into the support plate 15 to improve the robustness and stability of the equipment. A first groove 603 is formed on the top end face of the limit frame 6. The heating tube 7 is fitted into the first groove 603 of the limit frame 6 to precisely fix the heating tube 7 and heat the acrylic sheet. During heating, the target temperature is set through the control panel 9 to accurately control the temperature and improve product production efficiency.

[0035] The limiting frame 6 has a first through hole 601 and a second through hole 602. A second water nozzle 805 and a water outlet pipe 802 are inserted into the first through hole 601. A first water nozzle 804 and a water inlet pipe 801 are inserted into the second through hole 602. A pair of opposite end faces of the first water nozzle 804 and the second water nozzle 805 are integrally formed with U-shaped connecting water pipes 803. The U-shaped connecting water pipes 803 are connected to the first water nozzle 804 and the second water nozzle 805. A water pump is connected to the water inlet pipe 801 and the water outlet pipe 802. Cold water circulates through the water inlet pipe 801, the water outlet pipe 802, the U-shaped connecting water pipe 803, the first water nozzle 804, and the second water nozzle 805 to cool the limiting frame 6, preventing the heater from overheating, causing machine deformation and damage, and extending the service life of the equipment.

[0036] The sealing plug 16 is threadedly connected between the first water nozzle 804 and the inlet pipe 801, and between the outlet pipe 802 and the second water nozzle 805. The outer end faces of the first water nozzle 804, the inlet pipe 801, the outlet pipe 802, and the second water nozzle 805 that are in contact with the sealing plug 16 are all provided with external threads. The sealing plug 16 is provided with an internal thread that matches the external threads. The internal threads are threaded to the external threads to seal the connection between the first water nozzle 804 and the inlet pipe 801 and the connection between the outlet pipe 802 and the second water nozzle 805, so as to prevent water leakage.

[0037] A pair of sealing plugs 16 cover the connection between the first water nozzle 804 and the inlet pipe 801 and the connection between the outlet pipe 802 and the second water nozzle 805, respectively, to prevent water leakage and potential safety hazards.

[0038] like Figure 2 and Figure 5 As shown, the angle adjustment plate 10 is fixedly connected to the side wall end face of the outer shell 1. An arc-shaped through hole 1002 is provided on the angle adjustment plate 10. An angle scale 1001 is provided on one side end face of the angle adjustment plate 10 located at the arc-shaped through hole 1002. The angle scale 1001 provides intuitive angle indication, reducing errors. A bending plate 11 is connected between a pair of angle adjustment plates 10. A third threaded hole is provided on the bending plate 11, and a screw 1003 is threaded into the third threaded hole to achieve precise bending angle control. Specifically, after confirming the product processing angle, the screw 1003 is loosened. By controlling the screw 1003 to slide the bending plate 11 along the arc-shaped through hole 1002 to the target angle, the angle is confirmed by the angle scale 1001, and then the screw 1003 is tightened. The acrylic sheet can then be placed on the bending plate 11 for cooling and shaping, reducing human error and improving product quality control.

[0039] The rubber pad 14 is threaded to the bottom end face of the housing 1. The rubber material buffers the vibration of the equipment, enhances the stability of the equipment, avoids displacement of the equipment during processing, and ensures processing accuracy.

[0040] In use, depending on the required heating position of the acrylic sheet, first adjust the position of the positioning bracket 3 by loosening the screw 5 upwards. Determine the distance between the positioning bracket 3 and the heating tube 7 using the ruler 4. Tighten the screw 5 to fix the positioning bracket 3. Then, slide the bending plate 11 along the arc-shaped through hole 1002 to the target angle using the control screw 1003. After confirming the angle using the angle scale 1001, tighten the screw 1003. Turn on the external water pump of the water inlet pipe 801 and the water outlet pipe 802 to introduce cold water. Control the heating tube 7 to work using the boat-shaped switch socket 13. Adjust the temperature using the control panel 9 as needed. Place the acrylic sheet under the positioning bracket 3 to complete the local heating of the acrylic sheet and soften it locally. Then, bend the acrylic sheet along the heated area, placing it on the bending plate 11 during the bending process. Then, the acrylic sheet cools and sets, completing the operation.
