Description

Technical Field

[0001] This utility model relates to the field of rubber production equipment technology, and in particular to a rubber cutting machine. Background Technology

[0002] After initial molding, rubber products are mostly in the form of rubber sheets. Before further processing into finished products, these sheets need to be cut to produce appropriately sized rubber parts. Currently, the following problems exist in cutting rubber sheets:

[0003] 1. Manual cutting is inaccurate and inefficient, and cannot meet the needs of use;

[0004] 2. Rubber cutting machines are used for cutting, but currently used rubber cutting machines require belt conveyor when cutting rubber sheets. The belt is prone to slipping, and the ends of the rubber sheets to be cut are not supported during cutting, resulting in low cutting accuracy and affecting the pass rate of subsequent products. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a rubber cutting machine that improves cutting accuracy, is easy to use and simple to operate.

[0013] The positioning detection structure includes a detection bracket and several photoelectric switches fixedly installed on the detection bracket. The photoelectric switches are positioned downwards. Both ends of the detection bracket are fixed with slides that slide with the cutting table. Bolts are fixed downwards on the slides. The cutting table has grooves on both sides that slide with the bolts. The bolts pass through the grooves and are connected to nuts. A baffle is provided between the nut and the cutting table. The baffle has a clearance hole through which the bolt passes.

[0014] The rubber conveying structure includes two vertically arranged columns, with a mounting base fixedly installed at the upper end of each column. The rubber conveying structure also includes an upper conveying roller and a lower conveying roller, forming a conveying channel between them. Both ends of the upper and lower conveying rollers are connected to the mounting base via bearings. One end of each of the upper and lower conveying rollers passes through the mounting base and is fixedly connected to the output shafts of the upper and lower conveying motors, respectively. The upper and lower conveying motors are fixedly mounted on the mounting base.

[0015] The rubber sheet guiding structure includes two guide plates facing each other, and the distance between the guide plates and the feeding plate is less than the thickness of the rubber sheet.

[0016] The rubber sheet guide structure also includes a bidirectional screw. Two supports are fixedly installed on the feeding platform. The bidirectional screw is connected to the supports through bearings. The threads on the bidirectional screw turn in opposite directions from the middle to both ends. One end of the bidirectional screw passes through the support and is fixedly connected to the output shaft of the guide motor. The guide motor is fixedly installed on the support. Nut blocks are threaded to both ends of the bidirectional screw. The nut blocks are fixedly installed on the connecting block. The connecting block is fixedly connected to the guide plate.

[0017] The rubber sheet guide structure also includes two guide rods, both ends of which are fixedly connected to the loading platform via lugs. A guide sleeve is fixedly installed on the guide plate, and the guide sleeve slides in cooperation with the guide rod.

[0025] like Figure 1-5 As shown, a rubber cutting machine includes a feeding table 1, a cutting table 2, and a rubber conveying structure 3 disposed between the feeding table and the cutting table;

[0026] The loading platform includes a loading platform frame 4 and a loading plate 5 fixedly installed on the loading platform frame. A rubber sheet guide structure 6 is installed on the loading platform frame.

[0027] The cutting table includes a cutting table frame 7 and a support plate 8 fixedly installed on the cutting table frame. A blanking plate 9 is rotatably installed on the cutting table frame. A rotating structure for driving the blanking plate to rotate is installed on the cutting table frame. A cutting structure 10 is installed on the cutting table frame. The cutting structure includes a cutter 11. The cutter is positioned facing the end of the support plate near the blanking plate. A positioning detection structure 12 is also installed on the cutting table frame.

[0028] In this way, the rubber sheet is placed on the feeding plate and guided by the rubber sheet guide structure. One end of the rubber sheet is connected to the rubber conveying structure, which moves the rubber sheet to the cutting table. After the positioning detection structure detects that the rubber sheet has been conveyed to the correct position, the rubber conveying structure stops conveying. The cutting structure moves the cutter downward to cut the rubber sheet. Then, the rotating structure drives the unloading plate to rotate downward, and the cut rubber falls down, completing the cutting and unloading process.

[0029] Specifically, through the cooperation of the positioning detection structure and the rotating structure, the unloading platform can support the rubber sheet during cutting and unload it after cutting, thereby improving cutting accuracy.

[0030] In implementation, the rotating structure includes two hydraulic cylinders 13. Pins are fixed to both sides of the end of the material feeding plate near the support plate, and these pins are rotatably connected to the cutting table. An mounting rod 14 is fixed to the lower end of the cutting table, and the cylinder body of each hydraulic cylinder is rotatably connected to the mounting rod. A rotating rod 15 is fixedly installed at the end of the material feeding plate away from the support plate, and the cylinder rod of each hydraulic cylinder is rotatably connected to the rotating rod. When the material feeding plate is rotated, the cylinder rod of the hydraulic cylinder retracts, causing the material feeding plate to rotate downwards, allowing the cut rubber to slide down the material feeding plate.

[0031] In implementation, the cutting structure includes a mounting frame 16 fixedly installed on a cutting table. Several cylinders 17 are fixedly mounted on the mounting frame. The cylinder rods pass through the mounting frame and are fixedly connected to a blade holder 18. The cutter is fixedly mounted at the lower end of the blade holder. Sliding holes are provided at both ends of the blade holder. A sliding rod 19 is fixedly installed between the cutting table and the mounting frame, with the sliding holes and sliding rods engaging slidably. During cutting, the cylinders drive the blade holder and cutter downwards to cut the rubber sheet. The sliding rods and sliding holes guide the movement of the blade holder, improving cutting stability.

[0032] In implementation, the positioning detection structure includes a detection bracket 20 and several photoelectric switches 21 fixedly mounted on the detection bracket. The photoelectric switches are oriented downwards. Both ends of the detection bracket are fixed with slides 22 that slide against the cutting table. Bolts 23 are fixed downwards on the slides. Slide grooves 24 are provided on both sides of the cutting table to slide against the bolts. The bolts pass through the slide grooves and are connected to nuts. A baffle 25 is provided between the nut and the cutting table, and a clearance hole is provided through the baffle opposite the bolt. The photoelectric switches facilitate the detection of the rubber sheet's positioning, improving cutting accuracy. The slide grooves allow for adjustment of the positioning detection structure's position according to different cutting sizes, improving the overall adaptability of the device.

[0033] In implementation, the rubber conveying structure includes two vertically arranged columns 26, with mounting bases 27 fixedly installed at the upper ends of the columns. The structure also includes an upper conveying roller 28 and a lower conveying roller 29, forming a conveying channel between them. Both ends of the upper and lower conveying rollers are connected to the mounting bases via bearings. One end of each roller passes through the mounting base and is fixedly connected to the output shafts of an upper conveying motor 30 and a lower conveying motor 31, respectively. The upper and lower conveying motors are fixedly mounted on the mounting bases. The upper and lower conveying motors drive the upper and lower conveying rollers to rotate synchronously in opposite directions, thereby moving the rubber sheet and conveying it.

[0034] In practice, the rubber sheet guiding structure includes two guide plates 32 facing each other, and the distance between the guide plates and the feeding plate is less than the thickness of the rubber sheet;

[0035] The rubber sheet guide structure also includes a bidirectional screw 33. Two supports 34 are fixedly installed on the feeding platform. The bidirectional screw is connected to the supports through bearings. The threads on the bidirectional screw turn in opposite directions from the middle to both ends. One end of the bidirectional screw passes through the support and is fixedly connected to the output shaft of the guide motor 35. The guide motor is fixedly installed on the support. Nut blocks are threaded to both ends of the bidirectional screw. The nut blocks are fixedly installed on the connecting block 36. The connecting block is fixedly connected to the guide plate.

[0036] The rubber sheet guide structure also includes two guide rods 37. Both ends of the guide rods are fixedly connected to the loading platform through lugs 38. A guide sleeve 39 is fixedly installed on the guide plate, and the guide sleeve slides in cooperation with the guide rod.

[0037] When guiding the rubber sheet, the guide motor drives the bidirectional screw to rotate, which in turn drives the guide plate to move through the nut block and connecting block. The bidirectional screw can drive the two guide plates to move synchronously in opposite directions, quickly adjusting the guiding area. The guide rod guides the movement of the guide plate.

[0038] Specifically, it also includes PLC controllers, which are used to control the operation of the electrical components within them.

[0039] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
