[0002] When cutting cloth, leather and other materials, intelligent automatic cutting machines often position the materials through vacuum adsorption to prevent the materials from being moved by the cutter during cutting and to ensure cutting accuracy. Traditional cutting machines use a single vacuum pump for vacuuming, with a concentrated vacuuming area and uneven vacuuming, which can easily cause the material to deform.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1 The intelligent automatic cutting machine shown comprises a cutting bed 1 and a cutting mechanism 2 movably mounted on the cutting bed 1, wherein the cutting mechanism 2 is mounted on the cutting bed 1 via an X, Y, and Z three-axis moving module, so that the cutting mechanism 2 can move along the surface of the cutting bed 1. The cutting mechanism 2 can be a circular knife cutting head, a vibrating knife cutting head, or a laser cutting head.

[0025] The cutting bed 1 includes a rectangular frame 11 located outside, and an adsorption device (not shown) is installed in the frame 11. The adsorption device can be a vacuum pump or an exhaust fan. 4x3 adsorption chambers (not shown) are installed on the top of the frame 11. The adsorption chamber is an inverted cone structure. A through hole is opened at the bottom center of the adsorption chamber. The through hole is connected to the adsorption device through an air pipe. Each air pipe is respectively installed with a solenoid valve for controlling the opening and closing of the air pipe. The solenoid valve is electrically connected to the main control system of the cutting machine. The adsorption chamber is set to an inverted cone shape and the air pipe is connected to the center of the bottom of the adsorption chamber, which can improve the uniformity of adsorption of each adsorption chamber. The solenoid valve can also realize independent control of the adsorption chamber. If the raw material does not cover some adsorption chambers, these adsorption chambers can be closed by the solenoid valve to achieve the purpose of saving energy.

[0026] like Figure 1-4 As shown, each adsorption chamber is provided with an opening at the top, and adsorption plates 3 are installed at the openings. A plurality of vacuum holes 31 are arranged in an array on the adsorption plates 3, and a plurality of adsorption plates 3 are assembled into a cutting platform for placing cloth. Among them, a sealing strip is filled between the adsorption plate 3 and the top of the adsorption chamber to prevent air leakage between the adsorption plate 3 and the adsorption chamber. A shielding plate 4 is slidably installed on the lower side of the adsorption plate 3 located at the edge of the cutting platform. The shielding plate 4 is a plurality of long strip plates parallel to the edge of the cutting platform on the side where the adsorption plate 3 is located. The shielding plate 4 can be reciprocated in a direction perpendicular to the edge of the cutting platform on the side where the adsorption plate 3 is located, so that the shielding plate 4 can be moved to block the vacuum holes 31 on the adsorption plate 3, thereby closing the vacuum holes 31 on the edge of the adsorption plate 3 according to the size of the cloth.

[0027] like Figure 2-Figure 4As shown, as a preferred embodiment of the present application, the adsorption plate 3 is a rectangular plate, and a plurality of vacuum holes 31 are evenly opened on the adsorption plate 3. The vacuum holes 31 are arranged in a rectangular array, and the array surrounded by the vacuum holes 31 is parallel to the edge of the adsorption plate 3. Four cylindrical guide pillars 32 are fixed to the lower side of the adsorption plate 3, and an anti-slip block 33 is fixed to the lower end of the guide pillar 32. Preferably, the guide pillar 32 and the anti-slip block 33 can be hexagonal bolts.

[0028] like Figure 2-Figure 4 As shown, the shielding plate 4 is a rectangular plate, the width of the shielding plate 4 is half of the adsorption plate 3, and the length of the shielding plate 4 is less than the length of the adsorption plate 3, so that a position for overlapping with the adsorption chamber is reserved at the edge of the adsorption plate 3. Two parallel guide grooves 42 are provided on both sides of the long side of the shielding plate 4, the guide grooves 42 are parallel to the direction of the short side of the shielding plate 4, and the length of the guide grooves 42 is greater than the distance between the two guide pillars 32, so that the shielding plate 4 can slide a certain distance relative to the adsorption plate 3. Among them, the width of the guide groove 42 is greater than or equal to the outer diameter of the guide pillar 32 and less than the outer diameter of the anti-slip block 33, so as to prevent the shielding plate 4 from sliding off from the adsorption plate 3.

[0029] like Figure 2-4 As shown, a long strip-shaped adjustment hole 34 is provided in the middle of the adsorption plate 3, and the adjustment hole 34 is arranged parallel to the moving direction of the shielding plate 4. A toggle hole 43 is provided on the shielding plate 4, and the toggle hole 43 is located in the adjustment hole 34. Insert a tool such as a screwdriver into the toggle hole 43, and toggle the shielding plate 4 to move, so that the shielding plate 4 can be moved from the upper side of the adsorption plate 3. Preferably, grease can be filled between the shielding plate 4 and the adsorption plate 3, which can improve the smoothness of the movement of the shielding plate 4 on the one hand, and improve the sealing between the shielding plate 4 and the adsorption plate 3 on the other hand.

[0030] like Figure 2-Figure 4 As shown, the shielding plate 4 is provided with an avoidance hole 41, the inner end of the avoidance hole 41 is tangent to the inner end of the vacuum hole 32, and the diameter of the avoidance hole 41 is N times that of the vacuum hole 31, where N is the number of rows of the vacuum hole 31 from the outside to the inside. In order to ensure the structural strength of the shielding plate 4, the avoidance hole 41 can also be set in a long strip shape, and the length of the long strip avoidance hole 41 is N times that of the vacuum hole 31.

[0031] The working principle of the embodiment of the present application is as follows:

[0032] like Figure 5 As shown in the first row, in the initial state, the outer end of the shielding plate 4 coincides with the outer end of the adsorption plate 3, and at this time, all the vacuum holes 31 are in an open state;

[0033] like Figure 5 As shown in the second row, when the shielding plate 4 is moved one unit inward, the first row of vacuum holes 31 and the first row of avoidance holes 41 are offset, and the outermost row of vacuum holes 31 is closed;

[0034] like Figure 5 As shown in the third row, when the shielding plate 4 is moved one unit inward, the first and second rows of vacuum holes 31 are staggered with the first and second rows of avoidance holes 41, and the outermost two rows of vacuum holes 31 are closed;

[0035] like Figure 5 As shown in the fourth row, when the shielding plate 4 is moved one unit inward, the first, second and third columns of vacuum holes 31 are staggered with the first, second and third columns of avoidance holes 41, and the outermost three columns of vacuum holes 31 are closed.

[0036] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0037] By slidingly installing a shielding plate under the adsorption plate at the edge, the adsorption area of ​​the cutting platform can be adjusted according to the size of the material to be cut, reducing air leakage of the cutting platform, improving the accuracy of material positioning, and ensuring the quality of cutting.
