Description

Technical Field

[0001] This utility model relates to the field of plastic lunch box processing technology, and in particular to a one-time molding stamping equipment for plastic lunch boxes. Background Technology

[0002] Stamping is a common processing method in the manufacturing of plastic lunch boxes. Traditional plastic lunch box stamping equipment usually includes basic structures such as a mold base and stamping components. The stamping components press the plastic sheet placed on the mold base to form the shape of the lunch box. However, in actual production, traditional stamping equipment has some problems.

[0003] Traditional stamping equipment typically uses a single heating method when heating the mold base, such as overall heating or local heating, which makes it difficult to achieve precise temperature control in different areas of the mold base. This results in uneven heating of the plastic sheet during the stamping process, which can easily lead to local overheating or insufficient temperature, affecting the forming effect and product quality of the lunch box.

[0004] Therefore, to address the above problems, a one-time molding stamping equipment for plastic lunch boxes is proposed. By improving the heating method, zoned temperature control and flexible heating are achieved, which improves the stamping effect of plastic lunch boxes and the versatility of the equipment.

[0023] Please see Figure 3 and Figure 4 In this embodiment, the support assembly includes a connecting rod 201 and a base plate 202. The connecting rod 201 is disposed below the fixed seat 1, and the base plate 202 is disposed below the connecting rod 201. The support assembly also includes a bracket 203, which is disposed below the base plate 202. Multiple brackets 203 are provided. In use, the brackets 203 support the base plate 202. The adjustment assembly includes a first motor 301 and a threaded rod 302. The first motor 301 is disposed on one side of the fixed seat 1, and the output end of the first motor 301 is provided with a threaded rod 302. The threaded rod 302 is threadedly connected to the slider 103. In use, the first motor 301 is started to drive the threaded rod 302 to rotate, and the rotation of the threaded rod 302 drives the slider 103 to move linearly.

[0024] The stamping assembly includes a connecting frame 401, a second motor 402, and a first rotating shaft 403. The connecting frame 401 is located on one side of the fixed base 1, and the second motor 402 is located above the connecting frame 401. The first rotating shaft 403 is located at the output end of the second motor 402. In use, the first rotating shaft 403 is rotated by starting the second motor 402. The stamping assembly also includes a first bevel gear 404, a second bevel gear 405, and a second rotating shaft 406. The first bevel gear 404 is located at one end of the first rotating shaft 403, and the first bevel gear 404 and the first rotating shaft 403 are connected by a keyway. The second bevel gear 405 is located above the connecting frame 401, and the first bevel gear 404 and the second bevel gear 405 are meshed together. The second rotating shaft 406 is located inside the second bevel gear 405. The first shaft 403 rotates, driving the first bevel gear 404 to rotate, which in turn drives the second bevel gear 405 to rotate, which in turn drives the second shaft 406 to rotate. The stamping assembly also includes a connecting block 407, a hydraulic rod 408, and a stamping block 409. The connecting block 407 is located at one end of the second shaft 406, and the hydraulic rod 408 is located below the connecting block 407. The stamping block 409 is located at one end of the hydraulic rod 408. In use, the second shaft 406 rotates, driving the connecting block 407 to rotate, adjusting the angle of the stamping block 409. The extension and retraction of the hydraulic rod 408 drives the stamping block 409 to move up and down, stamping the plastic lunch box inside the mold base 2.

[0025] During operation, the temperature of different areas of the mold base 2 is first adjusted according to the molding requirements of the plastic lunch box. The first motor 301 is started, driving the threaded rod 302 to rotate, which in turn drives the slider 103 to move linearly. The slider 103 moves, causing the first heating resistor block 102 to move linearly, bringing it into contact with the outer surface of the mold base 2 for precise heating of the side of the mold base 2. Simultaneously, the second heating resistor block 106 heats the bottom surface of the mold base 2. Through the cooperation of multiple sets of first heating resistor blocks 102 and second heating resistor blocks 106, precise temperature control of different areas of the mold base 2 is achieved, ensuring uniform heating of the plastic sheet during stamping and improving the molding effect of the plastic lunch box.

[0026] After the mold base 2 is heated to the set temperature, a stamping operation is performed. First, the second motor 402 is started to drive the first rotating shaft 403 to rotate, which in turn drives the first bevel gear 404 to rotate. The rotation of the first bevel gear 404 drives the second bevel gear 405 to rotate, which in turn drives the second rotating shaft 406 to rotate. The rotation of the second rotating shaft 406 drives the connecting block 407 to rotate, adjusting the angle of the stamping block 409 to ensure that the stamping block 409 is aligned with the position of the plastic sheet in the mold base 2.

[0027] Then, the hydraulic rod 408 is activated to extend and retract, causing the stamping block 409 to move up and down. When the hydraulic rod 408 extends, the stamping block 409 moves downward to stamp the plastic sheet inside the mold base 2. After stamping is completed, the hydraulic rod 408 retracts, the stamping block 409 moves upward, and the formed plastic lunch box is removed.

[0028] Through the above steps, the first heating resistor block 102 is heated by the first wire 104 using the starting power supply 105. The first heating resistor block 102 is moved linearly by the slider 103. The first heating resistor block 102 contacts the outer surface of the mold base 2 by the linear movement of the first heating resistor block 102, thereby heating the side of the mold base 2. The second heating resistor block 106 is heated by the second wire 107 using the starting power supply 105, thereby heating the ground of the mold base 2. By using multiple sets of first heating resistor blocks 102 and second heating resistor blocks 106, different areas of the mold base 2 can be heated to achieve zoned temperature control and improve the stamping effect of plastic lunch boxes.
