[0026] In order to make the content of the utility model more easily and clearly understood, the utility model will be further described in detail below according to specific embodiments and in combination with the drawings.

[0027] As shown in Figure 2 , a scraper feeding device for composite board pressing production is used to separate stacked substrates, which comprises:

[0028] A material plate carrying table, on which the stacked substrates 1 are placed;

[0029] A conveying trolley, which is arranged on one side of the material plate carrying table;

[0030] A fixed frame body 2, which is installed on the conveying trolley and is provided with a threaded connection hole;

[0031] A rotating arm 3, the middle part of which is hinged to the fixed frame body 2, and the rear end of the rotating arm 3 is provided with a waist slot;

[0032] A lifting driving mechanism 5, one end of which is hinged to the fixed frame body 2, and the other end of which is a telescopic end, and the telescopic end of the lifting driving mechanism 5 is hinged to the front end of the rotating arm 3;

[0033] A substrate separation scraper 4, which is installed on the rear end of the rotating arm 3;

[0034] A down pressure adjusting mechanism 6, which passes through the waist slot of the rotating arm 3 and is threadedly connected with the threaded connection hole of the fixed frame body 2, and is adapted to be rotated to adjust the relative height between the lower edge of the substrate separation scraper 4 on the rear end of the rotating arm 3 and the edge of the top layer of the stacked substrates 1.

[0035] In the embodiment, as shown in Figure 2 The substrate 1 is stacked on the material plate carrier, the fixed frame body 2 is installed on the conveying trolley, and the substrate separation scraper 4 is connected to the fixed frame body 2 through the articulated rotating arm 3. When the lifting driving mechanism 5 is retracted, the telescopic end drives the front end of the rotating arm 3 to swing downward, so that the rear end of the rotating arm 3 rotates around the hinge point, thereby driving the substrate separation scraper 4 installed at the rear end of the rotating arm 3 to move upward. At the same time, the downward pressing adjusting mechanism 6 passes through the waist slot on the rotating arm 3 and is screwed to the threaded connection hole of the fixed frame body 2. By rotating the adjusting screw, the downward pressing adjusting mechanism 6 can move axially along the threaded connection hole, thereby pressing the rear end of the rotating arm 3 downward, and further accurately controlling the lowest position of the substrate separation scraper 4. By adjusting the downward pressing adjusting mechanism 6, the gap between the lower edge of the substrate separation scraper 4 and the edge of the top layer substrate 1 can be finely adjusted to ensure that the gap is always within the suitable separation range, that is, neither greater than the thickness of the substrate 1 to avoid multiple substrates 1 being pushed out at the same time, nor less than half the thickness of the substrate 1 to prevent the substrate 1 from not being fully separated or being damaged by scraping, thereby ensuring that the substrate 1 can be stably and smoothly separated and improving the reliability of the feeding. The conveying trolley is a prior art, and its specific structure is not described in detail in the embodiment.

[0036] Specifically, as shown in Figure 2 The substrate separation scraper 4 has a fixed part and an extension part connected thereto. The fixed part is arranged on the rear end of the rotating arm 3, and the extension part has a sheet-like structure, and the length direction of the extension part is arranged in parallel with the side edge of the stacked substrate 1 in the vertical direction.

[0037] Specifically, as shown in Figure 2 The extension part and the fixed part of the substrate separation scraper 4 are an integral structure.

[0038] Specifically, as shown in Figure 2 The length of the extension part of the substrate separation scraper 4 is greater than half the thickness of the substrate 1.

[0039] In the embodiment, as shown in Figure 2 The extension part of the substrate separation scraper 4 is designed to maintain a certain contact area when contacting and separating the edge of the substrate 1, so that the top layer substrate and the lower layer substrate can be stably separated during the separation process. The lower edge of the extension part is slightly inclined, and the rear end of the rotating arm 3 is in appropriate contact with the substrate, forming a wedge-shaped space for separation.

[0040] Specifically, as shown in Figure 2 The lifting driving mechanism 5 is a pneumatic cylinder.

[0041] Specifically, as shown in Figure 2 The downward pressing adjusting mechanism 6 is an adjusting screw, and the upper end of the adjusting screw is provided with an adjusting rotary head.

[0042] Specifically, as shown in Figure 2As shown, the front end of the rotating arm 3 is provided with an upwardly inclined guide surface.

[0043] In the embodiment, as shown, Figure 2 As shown, the upwardly inclined guide surface of the front end of the rotating arm 3 is designed to reduce the interference with the surrounding components during the extension and retraction of the cylinder 5. When the extension end of the cylinder 5 is retracted, the front end of the rotating arm 3 is lowered, and the rear end is raised, so that the base material separation blade 4 is lifted off the surface of the base material 1. When the extension end of the cylinder 5 is extended, the front end of the rotating arm 3 is raised, and the rear end is lowered, so that the base material separation blade 4 is in contact with the base material 1 and performs the separation operation.

[0044] The adjusting screw serves as a downward adjustment mechanism. The adjusting screw can be manually rotated through the adjusting rotary head at the upper end of the adjusting screw, so that the adjusting screw moves up and down in the threaded connection hole of the fixed frame body 2, thereby limiting the lowest position of the rear end of the rotating arm 3. The operator can accurately adjust the working position of the base material separation blade 4 according to the actual thickness of the base material 1, so as to ensure that only one layer of base material is separated each time, and to avoid the situation of missing separation or simultaneous separation of multiple layers.

[0045] The above-described specific embodiments further illustrate the technical problems solved by the utility model, the technical solutions and the beneficial effects. It should be understood that the above-described specific embodiments are only examples of the utility model, and are not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
