Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] Referring to Figures 1 to 4 , the utility model provides a technical scheme: a numerical control punch press waste collecting device, including support frame 1, support frame 1 one end is horizontal, the other end of support frame 1 is inclined upward, and the inclination angle is between 30 °-65 °, as Figure 1 And Figure 2 Indicated, the bottom of the inclined part of support frame 1 is provided with support frame body 6, and the bottom of support frame body 6 is provided with universal wheel 5 on both sides respectively, and the universal wheel 5 is a brake universal wheel, so that the brake positioning of universal wheel 5 is facilitated.

[0024] Support wheel 21 is rotatably arranged on both sides of the top of support frame 1, and support wheel 21 is connected through conveying belt 10, conveying belt 10 is conveying chain plate, and support wheel 21 is sprocket matched with the transmission chain on both sides of conveying belt 10. When installing, the transmission chain on both sides of conveying belt 10 is placed on support wheel 21. As Figure 3 Indicated, the specific mounting structure of support wheel 21 is that it is installed on first mounting shaft 23, then each first mounting shaft 23 is rotatably installed in bearing seat 20, and finally bearing seat 20 is installed on both sides of the top of support frame 1 respectively;

[0025] The support wheel 21 located at the top of the support frame 1 is driven to rotate by the driving device, which comprises a driving motor 7 arranged below the top of the support frame 1, and a support sprocket 9 is arranged on the rotating shaft of the driving motor 7 and the first mounting shaft 23, and the two support sprockets 9 are connected by a chain. At the same time, the two first mounting shafts 23 located at the top of the support frame 1 are connected by a connecting shaft 22, so that the two first mounting shafts 23 and the connecting shaft 22 are connected into a whole shaft, and the driving force provided by the driving motor 7 drives the two support wheels 21 to drive the conveyor belt 10 at the same time, so that the force on both sides of the top of the conveyor belt 10 is balanced.

[0026] Further, in order to tension the conveyor belt 10 and avoid bending and deformation of the conveyor belt 10 during rotation, as shown in Figure 1 and Figure 3 , a U-shaped bracket 12 is arranged at the bending position of the support frame 1, and the U-shaped bracket 12 is arranged downward, and the U-shaped bracket 12 is located outside the machine tool, and a lifting mechanism is arranged in the U-shaped bracket 12, as shown in Figure 1 and Figure 3 , the lifting mechanism comprises two guide rails 13 arranged on the inner walls of the U-shaped bracket 12 respectively, and a strip-shaped seat 14 is horizontally arranged between the two guide rails 13, and the strip-shaped seat 14 is slidably connected with the guide rails 13 through sliding blocks on both sides of the strip-shaped seat 14, so that the strip-shaped seat 14 can move up and down along the guide rails 13;

[0027] The bottom of the lifting mechanism is provided with a support 15 on both sides, specifically, the two ends of the bottom of the strip-shaped seat 14 are connected with the support 15, and the position of the support 15 corresponds to the two sides of the conveyor belt 10, and a tensioning wheel 16 is rotatably arranged at the bottom of each support 15, and the tensioning wheel 16 is also a sprocket, which matches with the transmission chain on both sides of the conveyor belt 10, as shown in Figure 1 , the specific mounting structure of the tensioning wheel 16 is that it is mounted on the second mounting shaft 24, and then the second mounting shaft 24 is rotatably arranged in the bottom of the support 15;

[0028] As shown in Figure 3 , an adjusting screw 11 is rotatably arranged in the middle of the strip-shaped seat 14, and the top of the adjusting screw 11 is threadedly arranged on the U-shaped bracket 12, so that when the adjusting screw 11 is rotated, it can be lifted in the U-shaped bracket 12, so that the adjusting screw 11 drives the strip-shaped seat 14 to lift, thereby adjusting the tension between the tensioning wheel and the conveyor belt 10, that is, under the driving of the lifting mechanism, the two tensioning wheels 16 are pressed on both sides of the conveyor belt 10, so that the conveyor belt 10 is tightened, and when the lifting mechanism rises, the conveyor belt 10 becomes loose, and at least one nut is arranged on the adjusting screw 11, and after the adjusting screw 11 is adjusted, the nut can be fastened on the U-shaped bracket 12.

[0029] Further, as shown in Figure 1As shown, baffles 19 extending above the support frame 1 are provided on the edges of the support frame 1, so that the conveyor belt 10 is located within the space enclosed by the baffles 19. Figure 3 As shown, two inclined plates 18 arranged in a "V" shape are provided above the conveyor belt 10, and the tops of the inclined plates 18 are connected to the strip beams 17 respectively.

[0030] Next, at least two support screws 4 are vertically provided at the bottom of the strip beam 17. The support screws 4 are movably placed in the mounting base 3. The mounting base 3 is installed on the top of both sides of the baffle plate 19. Each support screw 4 is provided with a fastening nut. When the support screw 4 is adjusted to the preset height, it can be fastened to the mounting base 3 by the nut. The bottom of the inclined plate 18 is placed above the surface of the conveyor belt 10.

[0031] It should be noted that setting the inclined plate 18 is essential, such as... Figure 1 As shown, the inclined plates 18 are arranged in a "V" shape to form a V-shaped material receiving device, and the two inclined plates 18 can increase the material receiving area at the top of the conveyor belt 10. When the debris from the machine tool outlet falls, it first falls on the inclined plates 18, and then falls along the inclined plates 18 onto the surface of the conveyor belt 10. Most importantly, the inclined plates 18 can concentrate the collected debris in the middle of the surface of the conveyor belt 10, preventing the debris from being scattered on the surface of the conveyor belt 10.

[0032] Furthermore, such as Figure 1 As shown, the bottom of the support frame 1 is sealed by a sealing plate 2, and a discharge channel 8 is provided below the top of the sealing plate 2, corresponding to the top of the conveyor belt 10. Figure 1 Figure 2 Figure 4 As shown, when the debris falls from the top of the conveyor belt 10, it lands directly in the discharge channel 8. There is usually a waiting container or fertilizer transport vehicle below the discharge channel 8, and the debris will fall directly into the waiting container or fertilizer transport vehicle.

[0033] Based on the above embodiments, it should be further explained that, since the "V"-shaped inclined plates 18 concentrate the debris in the middle of the conveyor belt 10, this prevents the debris from falling from both sides of the conveyor belt 10. In order to increase the conveying efficiency of the conveyor belt 10, protruding ridges can be provided on the surface of the conveyor belt 10, which helps to transport debris.

[0034] Based on the above embodiments, it should be further noted that at least one drain port is provided on the bottom of the sealing plate 2 or the side of the support frame 1, and a conduit is provided on the drain port to lead out the liquid.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
