Description

Technical Field

[0001] The invention relates to the technical field of mixing mills, and in particular to a stealth cutter device for mixing mills. Background Art

[0002] An open rubber mixing mill is a mechanical device used for hot refining, mixing, plasticating, and sheeting of rubber. It primarily consists of rollers, a spacing device, and a temperature control system. Rollers are typically made of alloy chilled cast iron for enhanced wear resistance.

[0003] After the existing open mill forms and discharges the material, it needs to be cut. Generally, the formed material is discharged and then cut. This cutting method is inefficient. Some equipment will set up some cutters on the outside to assist in cutting the material, which will increase the overall space of the equipment. When the material is cut, some of the material will adhere to the cutter. After the temperature drops, the adhered material solidifies and hardens, making it difficult to remove. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a stealth cutter device for a mixing mill, which can effectively solve the problems in the prior art that the cutter part occupies space and the material adhered to the cutter is difficult to remove.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides an open mill invisible cutter device, comprising a workbench and two open mill rollers rotatably mounted on the workbench, and further comprising:

[0007] The storage knife assembly includes a storage slot provided on the workbench, a baffle being slidably mounted on the storage slot, a plurality of slitting racks being rotatably mounted in the storage slot, and a cutter being rotatably mounted on each slitting rack, and the cutter being driven to fit the open refining roller by rotating the slitting rack;

[0008] The scraping assembly is used to clean the cutter, and includes a collection box fixedly installed in the storage groove. When the cutter is stored in the storage groove, its two sides are in contact with the side walls of the collection box, and a scraper plate is movably installed in the collection box.

[0009] Furthermore, a fixing frame is fixedly mounted on the workbench, a mounting frame is slidably mounted on the fixing frame, the refining roller is rotatably mounted on the mounting frame, and an adjusting member for driving the mounting frame to slide is provided on the fixing frame.

[0010] Furthermore, a first electric push rod is fixedly installed in the receiving groove, and a right-angle bracket is fixedly installed at the end of the output shaft of the first electric push rod, and the right-angle bracket and the baffle are fixedly connected.

[0011] Furthermore, a fixed roller frame is fixedly installed in the receiving groove, the slitting frame is rotatably installed on the fixed roller frame, a second electric push rod is rotatably installed on the bottom of the fixed roller frame, and the output shaft of the second electric push rod is rotatably connected to the slitting frame.

[0012] Furthermore, a transmission frame is fixedly installed on the side wall of the cutter, and a transmission member is connected between the transmission frames on two adjacent cutters, so that the cutters rotate synchronously through the transmission member. A drive motor for driving the cutters to rotate is provided on the outermost slitting frame.

[0013] Furthermore, the transmission member includes a plurality of permanent magnets fixedly mounted on the transmission frame, the plurality of permanent magnets are distributed in a ring shape, and the magnetic poles of two adjacent permanent magnets are opposite.

[0014] Furthermore, one side of the multiple collection boxes is commonly connected to a drive box, and the drive box and the multiple collection boxes are respectively connected. A linkage plate is slidably installed in the drive box, a linkage rod is fixedly installed on the side of the linkage plate close to the collection box, and a scraper plate is rotatably installed on the end of the linkage rod away from the linkage plate.

[0015] Furthermore, a second magnet is fixedly installed on one side of the scraper plate, and a first magnet is fixedly installed on the connecting rod. The first magnet is an electromagnet. When the scraper plate moves to the box opening of the collection box, the first magnet starts to repel the second magnet. When the scraper plate moves away from the box opening of the collection box, the first magnet is closed and attracted by the second magnet.

[0016] Furthermore, a first piston tube is fixedly installed on the outside of the drive box, and a first piston rod is movably inserted into one end of the first piston tube. The first piston rod passes through the outer wall of the drive box and is fixedly connected to the linkage plate.

[0017] Furthermore, a second piston tube is fixedly mounted on the first electric push rod, and a second piston rod is movably inserted into one end of the second piston tube, the end of the second piston rod is fixedly connected to the baffle, and a connecting tube is connected between the first piston tube and the second piston tube.

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example 1:

[0032] refer to Figure 1 , an open mill invisible cutting knife device, including a workbench 1 and two open refining rollers 3 rotatably mounted on the workbench 1, a fixed frame is fixedly mounted on the workbench 1, a mounting frame 2 is slidably mounted on the fixed frame, the open refining roller 3 is rotatably mounted on the mounting frame 2, and the fixed frame is provided with an adjusting member for driving the mounting frame 2 to slide, and also includes a storage knife assembly, including a storage slot 4 opened on the workbench 1, a baffle 5 is slidably mounted on the storage slot 4, a first electric push rod 6 is fixedly mounted in the storage slot 4, and the first A right-angle frame is fixedly installed at the end of the output shaft of the electric push rod 6, and the right-angle frame and the baffle 5 are fixedly connected. A plurality of slitting frames 9 are rotatably installed in the storage groove 4, and a cutter 10 is rotatably installed on each slitting frame 9. A fixed roller frame 7 is fixedly installed in the storage groove 4, and the slitting frame 9 is rotatably installed on the fixed roller frame 7. A second electric push rod 8 is rotatably installed on the bottom of the fixed roller frame 7. The output shaft of the second electric push rod 8 is rotatably connected to the slitting frame 9, and the cutter 10 is driven to fit the refining roller 3 by rotating the slitting frame 9.

[0033] like Figure 1 As shown, in order to save space, a storage slot 4 is opened on the workbench 1, and the cutter 10 is hidden in the storage slot 4. The slitting frame 9 is driven to rotate by the driving action of the second electric push rod 8, thereby controlling the cutter 10 to rotate out of the storage slot 4 and closely adhere to the refining roller 3 to cut the formed material. When the slitting is completed or no slitting is needed, the second electric push rod 8 is used to drive the slitting frame 9 to rotate to the storage slot 4, so that the cutter 10 is stored in the storage slot 4. This not only does not take up too much space, but also makes it convenient to cut the material at any time, thereby improving production efficiency.

[0034] Secondly, if Figure 2 and Figure 3 As shown, after the cutter 10 is stored in the storage groove 4, the baffle 5 can be driven by the first electric push rod 6 to block the notch of the storage groove 4 to prevent the material above from dripping into the storage groove 4 during melting and forming, thereby improving the quality of subsequent cutting.

[0035] Example 2:

[0036] refer to Figure 6 and Figure 7, a scraping assembly for cleaning the cutter 10 is also provided, which includes a collection box 15 fixedly mounted in the storage groove 4. When the cutter 10 is stored in the storage groove 4, its two sides are in contact with the side walls of the collection box 15. A scraper plate 20 is movably installed in the collection box 15. A transmission frame 12 is fixedly mounted on the side wall of the cutter 10. A transmission member is connected between the transmission frames 12 on the two adjacent cutters 10, and the cutters 10 are rotated synchronously by the transmission member. A drive motor 11 for driving the cutter 10 to rotate is provided on the outermost slitting frame 9. The transmission member includes a plurality of permanent magnets 13 fixedly mounted on the transmission frame 12. The plurality of permanent magnets 13 are distributed in a ring shape, and the magnetic poles of the two adjacent permanent magnets 13 are opposite. A drive box 14 is commonly connected to one side of the multiple collection boxes 15, and the drive box 14 and the multiple collection boxes 15 are respectively connected. A linkage plate 18 is slidably installed in the drive box 14, and a linkage plate 18 is fixedly mounted on one side of the linkage plate 18 close to the collection box 15. The first piston tube 16 is fixedly mounted on the outside of the driving box 14, and the first piston rod 17 is movably inserted into one end of the first piston tube 16. The first piston rod 17 passes through the outer wall of the driving box 14 and is fixedly connected to the linkage plate 18. The second piston tube 23 is fixedly mounted on the first electric push rod 6, and the second piston rod 24 is movably inserted into one end of the second piston tube 23. The end of the second piston rod 24 is fixedly connected to the baffle 5. A connecting tube 25 is connected between the first piston tube 16 and the second piston tube 23.

[0037] In order to keep the cutter 10 clean, a scraping assembly is set in the storage tank 4. When the cutter 10 is working, the scraping assembly does not work. After the cutting is completed, due to the high temperature of the material (caused by the forming process of the open mill), some materials adhere to the cutter 10. If they are not cleaned in time, as the temperature drops, the part of the material adhering to the cutter 10 solidifies and becomes more difficult to clean. Therefore, after the cutting is completed, the cutter 10 is rotated into the storage tank 4 along with the cutting frame 9. The cutter 10 will be placed between the two collection boxes 15, and the side wall of the cutter 10 is in full contact with the box opening of the collection box 15 (such as Figure 3 shown).

[0038] At this point, the drive motor 11 drives the cutter 10 to rotate. During this rotation, the cutter 10 will move relative to its sidewalls and the opening of the collection box 15, thereby scraping the material adhering to the cutter 10 into the collection box 15. The number of cutters 10 can be adjusted according to actual needs. Of course, an additional second electric push rod 8 is also required to drive it, and timely adjustment is made according to the actual number of cuts and the cutting spacing. During the cleaning process, it is necessary to ensure that each cutter 10 rotates. Therefore, a transmission member is provided between adjacent cutters 10. There are many ways to use the transmission member there. For example, when the distance between adjacent cutters 10 is small, a magnetic synchronization method can be used, that is, multiple magnetic points are provided on the transmission frame 12, and a permanent magnet is provided at each magnetic point. Adjacent transmission frames 12 are rotated synchronously by magnetic attraction (even if there is a delay, it does not matter, as long as each cutter 10 can complete the rotation). Of course, other synchronization methods can also be used, such as providing some blocks and buckles between the transmission frames 12. After storage, the synchronous rotation between the transmission frames 12 is completed by means of blocks and buckles. Of course, this operation is more troublesome, and the former is more recommended, which uses magnetic attraction to complete the rotation of all cutters 10. It should be noted here that, if Figure 3 As shown, when the distance between the two cutters 10 is far, a telescopic rod can be installed on one side of the cutter 10, and the transmission frame 12 can be installed on the telescopic rod. The telescopic rod can be used to shorten the distance between the permanent magnets 13 on different transmission frames 12, thereby achieving the purpose of completing the transmission.

[0039] The above-mentioned cleaning action of the cutter 10 is completed. The material is now accumulated at the box opening of the collection box 15. At this time, the baffle 5 is driven by the first electric push rod 6 to cover the collection tank 4. In the process of covering, Figure 4 As shown, the baffle 5 drives the second piston rod 24 to extend out of the second piston tube 23, and the air in the second piston tube 23 enters the first piston tube 16 through the connecting tube 25, and the first piston rod 17 is pushed out of the first piston tube 16 by air pressure. Figure 6 As shown, when the first piston rod 17 extends, the linkage plate 18 slides toward the box opening of the collection box 15, thereby driving multiple linkage rods 19 to move toward the box opening of the collection box 15. The end of the linkage rod 19 is provided with a scraper plate 20, and as shown Figure 7 As shown, the scraper plate 20 is rotatably installed, and a first magnet 21 is provided on the connecting rod 19. The first magnet 21 is an electromagnet, and a second magnet 22 (an ordinary permanent magnet) is provided on the scraper plate 20. In this way, when the first magnet 21 is powered off, the two will attract each other (the second magnet 22 attracts the first magnet 21), and when the first magnet 21 is started, the two will repel each other. The position of the scraper plate 20 is adjusted based on this principle, and the positions of the first magnet 21 and the second magnet 22 can adjust the direction of rotation of the scraper plate 20.

[0040] The purpose of setting the scraper plate 20 is that the scraper plate 20 is in the collecting box 15. Figure 7 In the state of the right half of the figure, it will not contact the inner wall of the collection box 15, and when the scraper plate 20 leaves the box opening of the collection box 15, the state of the scraper plate 20 is changed by magnetic force (such as Figure 7 (As shown in the left half of the figure), in this state, the scraper 20 not only scrapes the material on the inner wall of the collection box 15 into the collection box 15, but also scrapes the material that has not been cleaned off the cutter 10 into the collection box 15. The power on and off control method of the first magnet 21 is the existing technology and can be manual or automatic, depending on actual needs.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
