Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically to a control system for a household appliance protective foam laminating machine. Background Technology

[0002] Laminating machines can be divided into two main categories: instant laminating machines and pre-coating laminating machines. They are specialized equipment used for laminating paper, boards, and other materials. The laminating process involves pressing the materials together using rubber rollers and heated rollers to create a paper-plastic composite product. To improve the wear resistance of foam trays used in appliance packaging, a composite film is often applied to the surface of the foam tray.

[0003] The control system of the laminating machine controls its operation, and the eyes of the control system are generally photoelectric sensors. The photoelectric sensors are used to detect the position of the foam. When the foam reaches a specific position, the laminating machine must take the corresponding action. However, since the protective foam specifications of different household appliances are different, the placement position of the photoelectric sensors is also different. When laminating different foams, it is necessary to change the position of the photoelectric sensors. Existing laminating machines require disassembling and reassembling the sensors to change the photoelectric sensors, which is inconvenient.

[0004] To address the aforementioned issues, we have made improvements and proposed a control system for a home appliance protective foam coating machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a control system for a household appliance protective foam coating machine, including a frame. A coating machine body is installed in the middle of the frame, and a control system body is fixedly installed on the right side of the frame. A set of slide rails is installed on both the left and right sides of the frame. A slider is slidably connected inside the slide rails. A mounting groove is opened in the middle of the slider. A pair of friction blocks are slidably connected inside the mounting groove. An inclined surface is provided on the opposite side of the pair of friction blocks. An extrusion block is provided in the middle of the pair of friction blocks, and the shape of the extrusion block is an inverted trapezoid. A driving mechanism is provided between the extrusion block and the slider. A fixing frame is fixedly connected to the top of the slider. A photoelectric sensor is installed on the top of the fixing frame, and the output end of the photoelectric sensor is electrically connected to the input end of the control system body.

[0007] As a preferred technical solution of this utility model, the driving mechanism includes a threaded rod, which is rotatably connected to the middle of the slider. The outer side of the threaded rod is threadedly connected to the middle of the extrusion block. The top end of the threaded rod extends through to the upper end face of the slider, and a regular hexagonal protrusion is fixedly connected to the top end of the threaded rod.

[0008] As a preferred technical solution of this utility model, the bottom wall of the mounting groove is provided with a sliding groove, and the bottom end of the friction block is fixedly connected to a limiting block, which is slidably connected inside the sliding groove.

[0009] As a preferred embodiment of this utility model, a rotating base is fixedly connected to the top of the fixing frame, an mounting plate is installed on the top of the rotating base, and a photoelectric sensor is fixedly installed on the top of the mounting plate.

[0010] As a preferred embodiment of this utility model, a connecting ring is fixedly connected to the middle of the rotating base, and the connecting ring is rotatably connected to the bottom of the mounting plate.

[0011] As a preferred technical solution of this utility model, a protrusion is fixedly connected to the bottom end of the mounting plate, and springs are installed on both sides of the protrusion. The springs are arc-shaped, and a fixing block is fixedly connected to the end of the spring. The fixing block is fixedly connected inside the rotating base. A damper is provided on the inner side of the spring, and the two ends of the damper abut against the protrusion and the fixing block, respectively.

[0012] The beneficial effects of the utility model are:

[0013] 1. This utility model allows the slider to move along the slide rail, changing the position of the photoelectric sensor. Then, the drive mechanism works to make the extrusion block embed between a pair of friction blocks. The extrusion block presses the friction blocks outward, and the outer end face of the friction block is tightly attached to the inner wall of the slide rail. The position of the slider in the slide rail is fixed by friction, thereby fixing the position of the photoelectric sensor. This makes it easier to adjust the position of the photoelectric sensor and makes it more convenient to use.

[0014] 2. In this utility model, when the photoelectric sensor is impacted, the mounting plate rotates on the top of the rotating base via the connecting ring. During the rotation, the spring and damper in the direction of motion are compressed to buffer the photoelectric sensor. After the impact, the spring resets, causing the photoelectric sensor to reset as well, thus preventing the photoelectric sensor from shifting and thus avoiding affecting normal use.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1-4 As shown, a control system for a household appliance protective foam coating machine includes a frame 1, a coating machine body 2 installed in the middle of the frame 1, a control system body 3 fixedly installed on the right side of the frame 1, a set of slide rails 4 installed on both the left and right sides of the frame 1, a slider 6 slidably connected inside the slide rails 4, an installation groove 9 opened in the middle of the slider 6, a pair of friction blocks 11 slidably connected inside the installation groove 9, an inclined surface provided on the opposite side of the pair of friction blocks 11, an extrusion block 13 provided in the middle of the pair of friction blocks 11, and the shape of the extrusion block 13 is an inverted trapezoid, a driving mechanism is provided between the extrusion block 13 and the slider 6, a fixing frame 7 is fixedly connected to the top of the slider 6, a photoelectric sensor 5 is installed on the top of the fixing frame 7, and the output end of the photoelectric sensor 5 is electrically connected to the input end of the control system body 3, the internal main structure of the control system body 3 is a control microcontroller, and corresponding control buttons are externally connected;

[0023] When the position of the photoelectric sensor 5 needs to be changed, the squeezing block 13 is moved upward by the driving mechanism, so that the friction block 11 and the squeezing block 13 are no longer squeezed. At this time, the friction between the friction block 11 and the slide rail 4 is reduced, so the slider 6 can move along the slide rail 4 to change the position of the photoelectric sensor 5. Then the driving mechanism works to make the squeezing block 13 embed between a pair of friction blocks 11. The squeezing block 13 squeezes the friction block 11 outward, and the outer end face of the friction block 11 is tightly attached to the inner wall of the slide rail 4. The position of the slider 6 in the slide rail 4 is fixed by the friction force, thereby fixing the position of the photoelectric sensor 5, making it easier to adjust the position of the photoelectric sensor 5 and making it more convenient to use.

[0024] Specifically, such as Figure 3As shown, the driving mechanism includes a threaded rod 14, which is rotatably connected to the middle of the slider 6. The outer side of the threaded rod 14 is threadedly connected to the middle of the extrusion block 13. The top end of the threaded rod 14 extends through to the upper end face of the slider 6, and a regular hexagonal protrusion is fixedly connected to the top end of the threaded rod 14. By cooperating with the regular hexagonal protrusion through a wrench, the threaded rod 14 is rotated. The rotating threaded rod 14 drives the extrusion block 13 to move up and down inside the slider 6 through the thread.

[0025] Specifically, such as Figure 3 As shown, a sliding groove 10 is provided on the bottom wall of the mounting groove 9. A limiting block 12 is fixedly connected to the bottom end of the friction block 11, and the limiting block 12 is slidably connected inside the sliding groove 10. When the pressing block 13 acts on the friction block 11, the limiting block 12 slides along the sliding groove 10 to restrict the friction block 11.

[0026] Specifically, such as Figure 2 Figure 3 and Figure 4 As shown, a rotating base 15 is fixedly connected to the top of the mounting bracket 7. A mounting plate 8 is installed on the top of the rotating base 15, and the photoelectric sensor 5 is fixedly installed on the top of the mounting plate 8. A connecting ring 16 is fixedly connected to the middle of the rotating base 15, and the connecting ring 16 is rotatably connected to the bottom of the mounting plate 8. A protrusion is fixedly connected to the bottom of the mounting plate 8. Springs 17 are installed on both sides of the protrusion, and the springs 17 are arc-shaped. A fixing block 18 is fixedly connected to the end of the spring 17, and the fixing block 18 is fixedly connected inside the rotating base 15. A damper 19 is provided on the inner side of the spring 17, and the two ends of the damper 19 abut against the protrusion and the fixing block 18, respectively. When the photoelectric sensor 5 is impacted, the mounting plate 8 rotates on the top of the rotating base 15 through the connecting ring 16. During the rotation, the spring 17 and the damper 19 in the direction of movement are compressed to buffer the photoelectric sensor 5. After the impact, the spring 17 resets, causing the photoelectric sensor 5 to reset as well, preventing the photoelectric sensor 5 from shifting and thus avoiding affecting normal use.

[0027] Working principle: When the position of photoelectric sensor 5 needs to be changed, the extrusion block 13 is moved upward by the drive mechanism, so that the friction block 11 and the extrusion block 13 are no longer squeezed. At this time, the friction between the friction block 11 and the slide rail 4 is reduced, so that the slider 6 can move along the slide rail 4 to change the position of photoelectric sensor 5. Then the drive mechanism works to make the extrusion block 13 embed between a pair of friction blocks 11. The extrusion block 13 squeezes the friction block 11 outward, and the outer end face of the friction block 11 is tightly attached to the inner wall of the slide rail 4. The position of the slider 6 in the slide rail 4 is fixed by friction, thereby fixing the position of photoelectric sensor 5.

[0028] When the photoelectric sensor 5 is impacted, the mounting plate 8 rotates on the top of the rotating base 15 via the connecting ring 16. During the rotation, the spring 17 and damper 19 in the direction of motion are compressed to buffer the photoelectric sensor 5. After the impact, the spring 17 resets, causing the photoelectric sensor 5 to reset as well.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
