[0002] In the manufacturing and application of equipment for cutting sheet surface protective film, adjusting the height of the knife sleeve and the cutting tool is a critical step. In existing equipment designs, the knife sleeve is responsible for driving the tool movement, with its bottom pressing against the protective film, while the tool extends from the bottom of the knife sleeve to perform the task of cutting the protective film on the sheet surface. Therefore, the relative position between the bottom of the knife sleeve and the tip of the tool directly affects the accuracy and effectiveness of the film cutting, as well as the overall equipment operating efficiency and product quality. Currently, sheet surface protective film cutting equipment on the market generally uses tools such as micrometers to adjust the relative distance between the knife sleeve and the tool. Although micrometers can theoretically provide high-precision measurements, in practice, using micrometers to adjust the tool height is time-consuming and cumbersome, requiring workers to measure and adjust the tool height multiple times to reach the preset height. This not only increases labor intensity and reduces production efficiency, but can also lead to adjustment errors and height inconsistencies due to differences in workers' skill levels or experience.

The second driving member 21 can drive the knife 32 to rise and fall relative to the knife sleeve 31.

[0022] In an embodiment of the present invention, the sheet protective film cutting device further comprises a knife adjusting mechanism 4, which cooperates with the first drive mechanism 1 and the second drive mechanism 2 to realize automatic knife adjustment. Specifically, the knife adjusting mechanism 4 comprises a sensor 41, and the first drive member 11 can drive the knife sleeve 31 to descend to a preset position and trigger the sensor 41. When the sensor 41 is triggered, the system can record the position, and then the first drive member 11 drives the knife sleeve 31 to rise a certain distance.

[0023] The beneficial effects of the embodiments of the present utility model are as follows:

[0024] The sheet protective film cutting device of the present utility model embodiment is provided with a first driving mechanism 1, a second driving mechanism 2, a cutting mechanism 3 and a knife adjusting mechanism 4, wherein the first driving member 11 of the first driving mechanism 1 can drive the second driving mechanism 2 and the cutting mechanism 3 to rise and fall, the second driving member 21 of the second driving mechanism 2 can drive the knife 32 of the cutting mechanism 3 to rise and fall relative to the knife sleeve 31, the knife adjusting mechanism 4 is used to automatically adjust the knife sleeve 31 and the knife 32, wherein the knife adjusting mechanism 4 includes a sensor 41, the first driving member 11 can drive the knife sleeve 31 to descend to a preset position and trigger the sensor 41 The system can record the preset position and then drive the tool holder 31 to rise a certain distance. The second drive member 21 can drive the tool 32 to descend to the preset position and trigger the sensor 41. The system can record the preset position and then drive the tool 32 to rise a certain distance. The preset positions of the tool holder 31 and the tool 32 are the same, so they rise from the same height. By controlling the strokes of both, the tip of the tool 32 can be made flush with the bottom plane of the tool holder 31. When the tool 32 needs to be extended, the precise relative distance between the tool 32 and the tool holder 31 can be obtained, thereby achieving the effect of tool adjustment. In this process, no worker participation is required, and tool adjustment is automatically achieved. The tool adjustment error is small, the efficiency is high, the precision is high, and the uniformity is good.

[0025] In other embodiments, the sensor 41 is one or more of an infrared sensor, an inductive proximity sensor, and a laser displacement sensor. The infrared sensor can detect whether the knife sheath 31 or the tool 32 has reached a preset position by detecting whether infrared light is reflected. The inductive proximity sensor can detect whether the knife sheath 31 or the tool 32 has reached a preset position by detecting whether a metal object causes a change in the magnetic field. The laser displacement sensor can determine whether the knife sheath 31 or the tool 32 has reached a preset position by detecting the time it takes for a laser beam to be reflected from an object.

[0026] In this embodiment of the present invention, the sensor 41 is a pressure sensor. The pressure sensor generates an electric charge when subjected to pressure. The charge generation mechanism is not limited to the piezoelectric effect, strain effect, or capacitance effect. Once the charge is generated, it provides feedback indicating that the sheath 31 or the tool 32 has reached a predetermined position. The trigger force of the sensor 41 ranges from 0.05N to 1.2N. A trigger force less than 0.05N is prone to false triggering, while a trigger force greater than 1.2N is prone to errors due to the greater travel distance.

[0027] Specifically, the knife adjusting mechanism 4 also includes a knife setting cylinder 42, the sensor 41 is arranged on the top of the knife setting cylinder 42, and the knife setting cylinder 42 is arranged on the workbench. When the knife needs to be adjusted, the moving mechanism moves the cutting mechanism 3 to the top of the knife setting cylinder 42, and then the first driving member 11 can drive the tool sleeve 31 to contact the sensor 41, and the second driving member 21 can drive the tool 32 to contact the sensor 41.

[0028] In order to facilitate the contact between the sensor 41 and the tool sleeve 31 or the tool 32, a receiving groove 43 is provided on the top of the tool cylinder 42. The inner concave surface of the receiving groove 43 is an arc surface and its notch faces upward. The sensor 41 is arranged in the middle of the receiving groove 43, and the other positions of the receiving groove 43 are recessed in the sensor 41, which will not hinder the contact between the tool sleeve 31 or the tool 32 and the sensor 41.

[0029] Among them, a through hole 311 is provided at the bottom of the knife sleeve 31, and the tool 32 can pass through the through hole 311 and protrude from the bottom surface of the knife sleeve 31. The cross-sectional area of ​​the sensor 41 is larger than the cross-sectional area of ​​the through hole 311, so that when the knife sleeve 31 descends to the sensor 41, the sensor 41 can still contact the bottom of the knife sleeve 31 and will not be embedded in the through hole 311.

[0030] In order to protect the bottom of the tool sleeve 31, the edge of the slot of the accommodating groove 43 is provided with a first arc surface 431, and the first arc surface 431 is inclined from the edge of the accommodating groove 43 toward the center. The outer edge of the tool sleeve 31 is provided with a second arc surface 312, and the second arc surface 312 is inclined from the center of the tool sleeve 31 toward the edge. In the process of driving the tool sleeve 31 to descend and contact the tool cylinder 42, the second arc surface 312 can abut against the first arc surface 431. The contact force between the first arc surface 431 and the second arc surface 312 is less than the contact force between the planes. Therefore, setting the first arc surface 431 and the second arc surface 312 can reduce the impact and loss of the tool cylinder 42 on the bottom of the tool sleeve 31.

[0031] See also Figure 1In an embodiment of the utility model, the first driving mechanism 1 further includes a transmission screw 12 and a lifting seat 13. The transmission screw 12 is coaxially arranged with the movable end of the first driving member 11. The movable end of the first driving member 11 extends downward, and the transmission screw 12 is vertically arranged. The lifting seat 13 is sleeved outside the transmission screw 12 and meshed with the transmission screw 12. The second driving mechanism 2 and the cutting mechanism 3 are linearly connected with the lifting seat 13. When the first driving member 11 rotates, it can drive the lifting seat 13 to move up and down through the transmission screw 12, thereby driving the second driving mechanism 2 and the cutting mechanism 3 to move up and down.

[0032] See also Figure 3 The second drive mechanism 2 further includes a magnetic rod 22, one end of which is magnetically connected to the movable end of the second drive member 21, and the other end of which is magnetically connected to the cutter 32. The second drive member 21 can drive the cutter 32 to move up and down via the magnetic rod. The magnetic connection allows the cutter 32 to be moved up and down by the second drive member 21. At the same time, the connection between the cutter 32 and the second drive member 21 is movable, allowing the cutter 32 to rotate relative to the second drive member 21. This allows the cutter 32 to rotate relative to the second drive member 21 when turning when cutting the protective film, thereby maintaining the consistency of the cutting angle in the direction of travel.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
