Description

Technical Field

[0001] The utility model relates to the technical field of rubber preparation, in particular to a high-precision cutting device. Background Art

[0002] The main steps of rubber production include: plasticizing-mixing-calendering or extrusion-molding-vulcanization. In the calendering or extrusion process, the mixed rubber is passed through a calender or extruder to form a rubber sheet or rubber tube with a certain thickness or shape. The rubber sheet or rubber tube is commonly known as rubber mud because of its mud-like state. The rubber mud is sent to the molding equipment for further processing into the required product shape and size.

[0003] A Teflon conveyor belt is usually used to transfer the cement between the calendering station and the molding station. Since the Teflon conveyor belt is elastic, when the roller drives it, the position accuracy of the Teflon is easily deviated, resulting in the cement not being accurately transported to the cutting position of the molding equipment, which in turn results in insufficient shape and / or dimensional accuracy of the molded product. Therefore, those skilled in the art continue to seek methods that can improve the shape and dimensional accuracy of the cement molded product. Utility Model Content

[0033] Combined with Figure 1 and Figure 2 As shown, the high-precision cutting device of this embodiment can be used to cut the mastic 20 transported through the Teflon conveyor belt 10 to ensure that the product precision cut on the mastic 20 meets the requirements. Specifically, the device of this embodiment mainly includes: a frame 1, a cutting mechanism 2, a Z-axis driving mechanism 3, an X-axis driving mechanism 4, a Y-axis driving mechanism 5, and a position detection mechanism 6. Among them, the frame 1 is provided with a bearing table 11, and the Teflon conveyor belt 10 is located on the bearing table 11 and can move relative to the bearing table 11. The cutting mechanism 2 is installed on the frame 1 through the Z-axis driving mechanism 3, and the cutting mechanism 2 is located above the bearing table 11. When the Teflon conveyor belt 10 carries the mastic 20 and moves to the bearing table 11, the Z-axis driving mechanism 3 drives the cutting mechanism 2 to move downward to cut the mastic 20; the X-axis driving mechanism 4 is connected to the cutting mechanism 2 and is used to drive the cutting mechanism 2 to move along the X-axis. The Y-axis driving mechanism 5 is connected to the X-axis driving mechanism 4 and is used to drive the X-axis driving mechanism 4 to move along the Y-axis, thereby driving the cutting mechanism 2 to move along the Y-axis; the position detection mechanism 6 is arranged at the discharge end of the bearing table 11 and is used to detect the position of the cutting edge on the product cut by the cutting mechanism 2.

[0034] The device of this embodiment further includes an electronic control unit electrically connected to the Teflon conveyor belt 10, the Z-axis driving mechanism 3, the X-axis driving mechanism 4, the Y-axis driving mechanism 5, and the position detection mechanism 6. This electronic control unit is common knowledge in the automation equipment industry and belongs to the prior art, so it will not be described in detail here.

[0035] With the above structure, the high-precision cutting device of this embodiment detects the position of the cutting edge on the previous product discharged from the cutting mechanism 2 through the position detection mechanism 6. The detection mechanism transmits the cutting-edge position information to the electronic control unit, and the electronic control unit controls the X-axis drive mechanism 4 and / or the Y-axis drive mechanism 5 to drive the cutting mechanism 2 to move along the X and / or Y directions according to the received information, so as to correct the position of the cutting mechanism 2, and then cut out the next product on the clay 20 newly fed onto the carrier table 11, greatly improving the precision of the cut product.

[0036] Specifically, as Figure 3 shown, the Z-axis drive mechanism 3 of this embodiment includes: a Z-axis cylinder 31, a first Z-direction moving plate 32, a second Z-direction moving plate 33, a plurality of linear bearings 34 and a plurality of guide rods 35. The cylinder block of the Z-axis cylinder 31 is connected to the frame 1. Preferably, the Z-axis cylinder 31 is located below the carrier table 11, and the piston rod of the Z-axis cylinder 31 extends downward relative to its cylinder block and is connected to the first Z-direction moving plate 32. A plurality of linear bearings 34 are installed on the frame 1 (or the carrier table 11), and a plurality of guide rails correspond to the plurality of linear bearings 34 one by one. Each guide rail is inserted into the corresponding linear bearing 34. One end of the guide rail is connected to the first Z-direction moving plate 32 located below the carrier table 11, and the other end is connected to the second Z-direction moving plate 33 located above the carrier table 11. The cutting mechanism 2 is installed on the second Z-direction moving plate 33. When the piston rod of the Z-axis cylinder 31 expands and contracts, it can drive the cutting mechanism 2 to move up and down to realize the cutting of the clay 20.

[0037] As Figure 4 and Figure 5 shown, the Y-axis drive mechanism 5 of this embodiment includes: a Y-axis electric cylinder 51, a first guide rail 52 and a first sliding seat 53. Among them, the cylinder block of the Y-axis electric cylinder 51 and the first guide rail 52 are respectively installed on the second Z-direction moving plate 33 of the Z-axis drive mechanism 3 and can move up and down with the second Z-direction moving plate 33. The first sliding seat 53 is slidably connected to the first guide rail 52, and the first sliding seat 53 is also fixedly connected to the output shaft of the Y-axis electric cylinder 51. When the output shaft of the Y-axis electric cylinder 51 moves in the Y direction, the first sliding seat 53 can move along the Y direction accordingly, thereby driving the X-axis drive mechanism 4 installed on the first sliding seat 53 to move, and further driving the cutting mechanism 2 to move along the Y direction.

[0038] As Figure 4 and Figure 5As shown in the figure, the X-axis driving mechanism 4 of this embodiment includes: an X-axis electric cylinder 41, a second guide rail 42, and a second sliding seat 43. The cylinder block of the X-axis electric cylinder 41 and the second guide rail 42 are both installed on the first sliding seat 53 of the Y-axis driving mechanism 5. The second sliding seat 43 is connected to the output shaft of the X-axis electric cylinder 41, and the second sliding seat 43 is also slidably connected to the second guide rail 42. The cutting mechanism 2 is installed on the second sliding seat 43. When the output shaft of the X-axis electric cylinder 41 moves in the X direction, it can drive the second sliding seat 43 and the cutting mechanism 2 thereon to move in the X direction.

[0039] As Figure 6 shown in the figure, the cutting mechanism 2 of this embodiment includes a mounting plate 21 and a cutting knife 22. Among them, the mounting plate 21 is used to connect to the second sliding seat 43 of the X-axis driving mechanism 4, and the cutting knife 22 is connected to the mounting plate 21. The contour of the cutting knife 22 is the same as the contour of the product to be cut.

[0040] As Figure 2 shown in the figure, the position detection mechanism 6 of this embodiment includes a bracket 61 and a CCD camera 62. The bracket 61 is fixed to the frame 1 and is located at the discharging end of the carrying platform 11. The CCD camera 62 is installed on the bracket 61. When the installation space is sufficient, the CCD camera 62 is as close as possible to the discharging end of the carrying platform 11, so as to detect the position of the cutting edge on the product as soon as possible and feed the information back to the electronic control unit, thereby improving the timeliness of the position correction of the cutting mechanism 2 and improving the production efficiency.

[0041] As Figure 2 shown in the figure, at least one set of limiting mechanisms is further provided on the carrying platform 11 of this embodiment. The limiting mechanism includes two limiting blocks 7. The two limiting blocks 7 are distributed on both sides of the Teflon conveyor belt 10 along the direction perpendicular to the running direction of the Teflon conveyor belt, that is to say, the two limiting blocks 7 are distributed on both sides of the Teflon conveyor belt 10 in the X direction to limit the large deviation of the Teflon conveyor in the X direction during operation, improve its transmission accuracy of the clay 20, and further improve the cutting accuracy of the product.

[0042] In summary, the working process of the high-precision cutting device in this embodiment is as follows: The Teflon conveyor belt 10 transports the clay 20 to the carrier table 11, and the Z-axis driving mechanism 3 drives the cutting mechanism 2 to move towards the clay 20 to cut out the first product. As the first product on the carrier table 11 is discharged to the CCD camera 62, the CCD camera 62 collects the position information of the points for position detection on the first product (in this embodiment, a certain position in the lower right corner of the product blade can be used as the position detection point) and feeds this information back to the electronic control unit. The electronic control unit determines whether the position of the first product deviates from the preset position based on the received information. If the position of the first product deviates from the preset position, it controls the X-axis driving mechanism 4 and the / Y-axis driving mechanism 5 to move the cutting mechanism 2 to correct the position of the cutting tool 22. The cutting tool 22 after position correction then cuts out the second product on the clay 20 fed onto the carrier table 11, and the above actions are repeated in a cycle.

[0043] In the present utility model, specific embodiments are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
