After being conveyed to the appropriate position, the blocking cylinder extends, causing the blocking plate to block the material frame. Simultaneously, the conveyor line stops conveying. Then, the servo motor drives the adjusting screw to rotate, thereby moving the support plate so that the sensing block contacts the material frame. At the same time, the servo motor stops running. Then, the extension of the latch cylinder causes the latch to move, releasing the material frame's lock. Simultaneously, the two guide rail cylinders extend, adjusting the fixing claws to fix one side of the material frame. Then... The width of the material frame can be adjusted. The rotation of the servo motor drives the support plate and one side of the material frame to move, thereby adjusting its width. When the preset width is reached, the servo motor stops running, the latch cylinder retracts, and then the pressure cylinder extends to push the latch on one side of the material frame, thus securing the movable edge of the material frame. Then the guide rail cylinder retracts, completing the width adjustment. Finally, the blocking cylinder retracts, and the conveyor line can send out the widened material frame. In use, the entire material frame width adjustment is automatically completed by the width adjustment machine, which improves the efficiency of material frame width adjustment, saves labor costs, and has high accuracy and strong practicality.

[0025] Example 1: An automatic width adjustment machine for a material frame includes a machine body 1 and a material frame 2. The surface of the machine body 1 is provided with an inlet and outlet. A conveyor line 3 is installed at the inlet and outlet of the machine body 1. An automatic width adjustment structure 4 is provided inside the machine body 1.
[0026] The automatic width adjustment structure 4 includes a base plate 5 fixedly connected inside the body 1. Two vertical plates 6 are fixedly connected to the upper surface of the base plate 5. An adjusting screw 7 is rotatably connected between the two vertical plates 6. A screw sleeve 8 is threaded onto the surface of the adjusting screw 7. A connecting plate 9 is fixedly connected to the surface of the screw sleeve 8. A crossbar 10 is fixedly connected to the surface of the connecting plate 9. One end of the crossbar 10 extends to the outside of one of the vertical plates 6 and is fixedly connected to a support plate 11. A slot is opened on the surface of one of the vertical plates 6, and the crossbar 10 can slide inside the slot.
[0027] Example 2: The difference between this example and Example 1 is that, in this example, each of the four corners of the support plate 11 is fixedly equipped with a latch cylinder 12, and each of the four latch cylinders 12 is fixedly connected with a latch 13. Each of the four corners of the back of the support plate 11 is fixedly connected with a pressure cylinder 14. Two guide rail cylinders 15 are fixedly connected to the surface of the support plate 11, and each of the two guide rail cylinders 15 is fixedly connected with a fixing claw 16, which facilitates unlocking and locking of the movable side of the material frame 2 and facilitates subsequent adjustment of the width of the material frame 2.
[0028] Example 3: The difference between this example and Example 1 is that a blocking cylinder 17 is fixedly installed inside the machine body 1, and a blocking plate 18 is fixedly connected to the output end of the blocking cylinder 17. A slot is opened in the middle of the conveyor line 3, and the blocking plate 18 can move inside the slot to block the material frame 2, move it to a suitable position, and keep it stable during the width adjustment process.
[0029] Example 4: The difference between this example and Example 1 is that a servo motor 19 is fixedly connected to the surface of another vertical plate 6. The output end of the servo motor 19 passes through the connected vertical plate 6 and is fixedly connected to one end of the adjusting screw 7. The rotation of the servo motor 19 can drive the support plate 11 to move, thereby facilitating width adjustment.
[0030] Example 5: The difference between this example and Example 1 is that four guide shafts 20 are fixedly connected to the surface of the connecting plate 9, and the other end of each of the four guide shafts 20 is fixedly connected to the support plate 11. Four movable grooves are provided on the surface of one of the vertical plates 6, and the four guide shafts 20 can move in the corresponding movable grooves respectively, which facilitates the restriction of the movement of the support plate 11 and makes its movement more stable and smooth.
[0031] Example 6: The difference between this example and Example 1 is that the support plate 11 has two through holes on its surface. A material frame mounting position sensing block 21 is slidably installed inside the two through holes. A sensing baffle 23 is fixedly connected to one end of the sensing block 21. A position sensor 24 matching the sensing baffle 23 is installed on the back of the support plate 11. A PLC control panel 22 is provided on the surface of the machine body 1. The position sensor 24, the conveyor line 3, the servo motor 19, the latch cylinder 12, the pressure cylinder 14, the guide rail cylinder 15, the blocking cylinder 17, and the sensing block 21 are all electrically connected to the PLC control panel 22, which allows the user to automatically control each component through the PLC control panel 22.
[0032] In summary, the automatic width adjustment machine for the material frame, the PLC control panel 22, and the multiple cylinders and servo motors 19 are all existing technologies on the market. Each component is controlled by the PLC control panel 22. This control structure and method are not essential technical features of this utility model and will not be described here. In use, the material frame 2 is placed on the conveyor line 3. After being conveyed to the appropriate position by the conveyor line 3, the blocking cylinder 17 extends, driving the blocking plate 18 to block the material frame 2. Simultaneously, the conveyor line 3 stops conveying. Then, the operation of the servo motor 19 drives the adjusting screw 7 to rotate, thereby moving the support plate 11 so that the sensing top block 21 contacts the material frame 2. Then, the sensing top block 21 drives the sensing baffle 23 to move. When the sensing baffle 23 contacts the positioning sensor 24, the servo motor 19 stops operating. Then, the latching cylinder 1... The extension of cylinder 2 causes the latch 13 to move, releasing the latch of the material frame 2. At the same time, the two guide rail cylinders 15 extend to adjust the fixing claw 16 to fix one side of the material frame 2. Then the width of the material frame 2 can be adjusted. The rotation of the servo motor 19 drives the support plate 11 and one side of the material frame 2 to move, adjusting its width. When the preset width is reached, the servo motor 19 stops running, the latch cylinder 12 retracts, and then the pressing cylinder 14 extends to push the latch on one side of the material frame 2, making the movable edge of the material frame 2 tight. Then the guide rail cylinder 15 retracts, completing the width adjustment. Then the blocking cylinder 17 retracts, and the conveyor line 3 can send out the widened material frame. In use, the entire material frame width adjustment is automatically completed by the width adjustment machine, which improves the efficiency of material frame width adjustment, saves labor costs, and has high accuracy and strong practicality.
