Description

Technical Field

[0001] The utility model relates to the technical field of rubber preparation, and specifically relates to a waste removal device. Background Art

[0002] Raw rubber is formed into a film or a rubber tube with a certain thickness or shape after plasticizing - mixing - calendaring. In the industry, the film or the rubber tube is called mastic. The mastic is processed into a blank with a certain shape by a cutting device, and the blank forms a rubber product after vulcanization.

[0003] Since the mastic has a soft property, during transportation and when it is placed in a cutting device for cutting, the whole mastic needs to be supported to avoid deformation of the mastic due to lack of support, which in turn affects the cutting accuracy. Therefore, it is not convenient to set a hollow structure in the cutting device to discharge waste. In other words, when the blank exits from the cutting device, the waste and the blank are still not separated, and the waste is still on the conveyor belt. How to separate the blank and the waste after cutting the mastic is a problem that those skilled in the art have been continuously working on to solve. Summary of the Utility Model

[0004] In order to overcome the defects in the prior art, an embodiment of the utility model provides a waste removal device, which can remove waste on the premise of ensuring sufficient support for the product blank, and the mastic waste will not remain on the Teflon conveyor belt.

[0005] An embodiment of the present application discloses: a waste removal device, which is arranged at the discharge end of a cutting device, and includes:

[0006] A workbench;

[0007] A stripping mechanism, including a first support, a first supporting plate, a second supporting plate and a rotating shaft. The first support is connected to the workbench. The first supporting plate and the second supporting plate are installed on the first support at intervals. The first supporting plate is located on the side of the second supporting plate close to the cutting device. The rotating shaft is rotatably connected to the first support and is located below the first supporting plate and the second supporting plate;

[0008] A Teflon conveyor belt, which is sequentially connected to the first supporting plate, the rotating shaft and the second supporting plate. The inner side of the Teflon conveyor belt contacts the first supporting plate and the second supporting plate, and the outer side of the Teflon conveyor belt contacts the rotating shaft;

[0009] A suction mechanism, which is installed on the workbench and is used for sucking and moving the waste.

[0010] Specifically, there is a gap between the first supporting plate and the second supporting plate, and the rotating shaft is located directly below the gap.

[0011] Specifically, the gap is smaller than the shaft diameter of the rotating shaft.

[0012] Specifically, the ends of the first supporting plate and the second supporting plate facing the gap are respectively rounded.

[0013] Specifically, the second supporting plate has a blowing area corresponding to the waste material. A plurality of first through holes are provided in the blowing area. A bottom plate is connected below the second supporting plate. A groove is provided on one side of the bottom plate facing the second supporting plate. At least one second through hole for communicating the groove and the blowing system is further provided on the bottom plate.

[0014] Specifically, the sucking mechanism includes a second bracket, a horizontal driving unit, a vertical driving unit, and a sucking unit. The second bracket is connected to the workbench. The horizontal driving unit is installed on the second bracket. The vertical driving unit is connected to the horizontal driving unit. The sucking unit is connected to the vertical driving unit.

[0015] Specifically, the horizontal driving unit includes a first gear, a second gear, a belt, a motor, a sliding plate, and a guide rail. The first gear and the second gear are respectively installed on the second bracket and connected by the belt. The first gear or the second gear is connected to the output shaft of the motor. The sliding plate is fixedly connected to the belt and slidably connected to the guide rail. The vertical driving unit is a cylinder, and the cylinder block of the cylinder is connected to the sliding plate.

[0016] Specifically, the sucking unit includes a mounting plate, a plurality of suction cups, and a vacuum system. The mounting plate is connected to the vertical driving unit. The plurality of suction cups are installed on the mounting plate and respectively communicated with the vacuum system.

[0017] The utility model has at least the following beneficial effects:

[0018] 1. For the waste removal device of this embodiment, its stripping mechanism includes a first supporting plate and a second supporting plate arranged at intervals. A rotating shaft is arranged below the two supporting plates, and the Teflon conveyor belt bypasses below the rotating shaft. Thus, when the product blank and the waste material run to the interval between the first supporting plate and the second supporting plate along with the Teflon conveyor belt, the product blank and the waste material can be temporarily separated from the Teflon conveyor belt, realizing the stripping of the product blank and the waste material and reducing the adhesion force between the two and the Teflon conveyor belt. As the product blank and the waste material continue to move, the two come into contact with the Teflon conveyor belt again and are supported. However, due to the decrease in the bonding strength between the two and the Teflon conveyor belt, it is easy for the sucking mechanism to suck and remove the waste material.

[0019] 2. When the blowing system of this embodiment blows air into the groove through the second through hole, the gas in the groove overflows upward through the first through hole on the second supporting plate to generate an upward thrust on the waste material, further reducing the adhesion force between the waste material and the Teflon conveyor belt, which is beneficial for the suction mechanism to suck the waste material and avoid the waste material remaining on the Teflon conveyor belt.

[0033] In addition, the terms "first", "second", etc. are only used for distinction in description and do not have special meanings.

[0034] Such as Figure 1As shown in the figure, the waste removal device of this embodiment is arranged at the discharge end of the cutting device 10, and is used to separate the product blank 30 and the waste 20 discharged from the cutting device 10, and remove the waste 20 into the waste box. The product blank 30 separated from the waste 20 is conveyed to the next working station.

[0035] Combined with Figures 2 to 4 As shown in the figure, the waste removal device of this embodiment mainly includes: a workbench 1, a peeling mechanism 2, a Teflon conveyor belt 3, and a suction mechanism 4. Among them, the peeling mechanism 2 includes a first bracket 21, a first support plate 22, a second support plate 23, and a rotating shaft 24; the first bracket 21 is connected to the workbench 1, the first support plate 22 and the second support plate 23 are spaced apart and installed on the first bracket 21, the first support plate 22 is located on the side of the second support plate 23 close to the cutting device 10, and the rotating shaft 24 is rotatably connected to the first bracket 21. In other words, the rotating shaft 24 is rotationally connected to the first bracket 21, and the rotating shaft 24 is located below the first support plate 22 and the second support plate 23. The Teflon conveyor belt 3 is used to convey the product blank 30 and the waste 20 into the peeling mechanism 2 and convey the product blank 30 to the next working station. Along the direction from the feeding end to the discharging end of the peeling mechanism 2, the Teflon conveyor belt 3 is sequentially connected to the first support plate 22, the rotating shaft 24, and the second support plate 23. Specifically, the Teflon conveyor belt 3 is annular, including an inner side and an outer side opposite to each other. Its inner side contacts the first support plate 22 and the second support plate 23, and the outer side contacts the rotating shaft 24. In other words, the Teflon conveyor belt 3 passes above the first support plate 22, then bypasses below the rotating shaft 24, and then passes above the second support plate 23. The suction mechanism 4 is installed on the workbench 1 and is used to suck and move the waste 20 running on the second support plate 23 into the waste box.

[0036] With the above structure, in the waste removal device of this embodiment, the peeling mechanism 2 includes a first support plate 22 and a second support plate 23 arranged at intervals, a rotating shaft 24 is arranged below the two support plates, and the Teflon conveyor belt 3 bypasses below the rotating shaft 24. In this way, when the product blank 30 and the waste 20 run with the Teflon conveyor belt 3 to the interval between the first support plate 22 and the second support plate 23, the product blank 30 and the waste 20 can be separated from the Teflon conveyor belt 3 briefly, realizing the peeling of the product blank 30 and the waste 20 and reducing the adhesion force between the two and the Teflon conveyor belt 3. As the product blank 30 and the waste 20 continue to move, the two come into contact with the Teflon conveyor belt 3 again and are supported, but due to the decrease in the bonding strength between the two and the Teflon conveyor belt 3, it is easy for the suction mechanism 4 to suck and remove the waste 20.

[0037] Figure 4 is a cross-sectional view of the peeling mechanism of this embodiment perpendicular to the axis of the rotating shaft 24. AsFigure 4 As shown, a gap is formed between the first supporting plate 22 and the second supporting plate 23 of this embodiment, and the rotating shaft 24 is located directly below this gap. Preferably, the above-mentioned gap is smaller than the shaft diameter of the rotating shaft 24. In other words, the distance between the first supporting plate 22 and the second supporting plate 23 is smaller than the shaft diameter of the rotating shaft 24. Preferably, this gap is less than or equal to 1 cm. In this way, on the premise of satisfying the short-term separation of the product blank 30 and the waste 20 from the Teflon conveyor belt 3, it is possible to avoid the downward deformation of the product blank 30 and the waste 20 due to the lack of support for a long time and a long distance, thereby affecting their continued movement to the next station.

[0038] Furthermore, continuing to refer to Figure 4 , a fillet is provided at one end of the first supporting plate 22 facing the above-mentioned gap (or facing the second supporting plate 23), and a fillet is provided at one end of the second supporting plate 23 facing the gap (or facing the first supporting plate 22). With this solution, on the one hand, the fillet can avoid the rapid wear of the Teflon conveyor belt 3, and on the other hand, it can also avoid the product blank 30 and the waste 20 from being scratched when feeding into the second supporting plate 23.

[0039] Combined with Figure 4 and Figure 5 shown, the second supporting plate 23 of this embodiment has a blowing area corresponding to the waste 20, and a plurality of first through holes 231 are provided in this blowing area. Combined with Figure 5 and Figure 6 shown, a bottom plate 5 is further connected below the second supporting plate 23. A groove 51 is provided on one side of the bottom plate 5 facing the second supporting plate 23. The area of the groove 51 can cover the area of the blowing area. At least one second through hole 52 is also provided on the bottom plate 5, and this second through hole 52 is used to communicate the groove 51 and the blowing system. With the above solution, when the blowing system blows air into the groove 51 through the second through hole 52, the gas in the groove 51 overflows upward through the first through holes 231 on the second supporting plate 23 to generate an upward thrust on the waste 20, further reducing the adhesion between the waste 20 and the Teflon conveyor belt 3, which is beneficial to the suction mechanism 4 to suck the waste 20 and avoid the waste 20 remaining on the Teflon conveyor belt 3.

[0040] Combined with Figure 1 and Figure 2As shown in the figure, the suction mechanism 4 of this embodiment includes a second support 41, a horizontal drive unit, a vertical drive unit, and a suction unit 44. Among them, the second support 41 is connected to the workbench 1, the horizontal drive unit is installed on the second support 41, the vertical drive unit is connected to the horizontal drive unit, and the suction unit 44 is connected to the vertical drive unit. Specifically, the horizontal drive unit includes a first gear 421, a second gear 422, a belt 423, a motor (not shown in the figure), a sliding plate 424, and a guide rail 425. The first gear 421 and the second gear 422 are respectively installed on the second support 41 and connected by the belt 423. The first gear 421 or the second gear 422 is connected to the output shaft of the motor. The sliding plate 424 is fixedly connected to the belt 423, and the sliding plate 424 is also slidably connected to the guide rail 425. The vertical drive unit is a cylinder 43, and the cylinder body of the cylinder 43 is connected to the sliding plate 424. The suction unit 44 includes a mounting plate, a plurality of suction cups, and a vacuum system. The mounting plate is connected to the piston rod of the cylinder 43. The plurality of suction cups are installed on the mounting plate and are respectively communicated with the vacuum system. The vacuum system can control the suction cups to suck and release the waste 20.

[0041] In summary, the working process of the waste removal device of this embodiment is as follows: With the movement of the Teflon conveyor belt 3, the product blank 30 and the waste 20 discharged from the cutting device 10 sequentially run to the first support plate 22 and the second support plate 23, and when passing through the gap between the first support plate 22 and the second support plate 23, they are initially separated from the Teflon conveyor belt 3 and the adhesion force is reduced; when the product blank 30 and the waste 20 completely run onto the second support plate 23, the Teflon conveyor belt 3 stops running. The horizontal drive unit and the vertical drive unit of the suction mechanism 4 drive the suction unit 44 to move until the suction cups contact the waste 20. The vacuum system is started so that the suction cups suck the waste 20. At the same time, the blowing system is started to blow air to the waste 20. The suction mechanism 4 moves the waste 20 into the waste box, and the Teflon conveyor belt 3 continues to run.

The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
