Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a multi-blade rubber slitting machine. Background Technology

[0002] Rubber slitting machines are mainly used to cut wide rubber rolls into narrow strips of the required width, and the slitting strips can be made into various rubber products according to requirements.

[0003] Currently, slitting machines that use circular blades as the main cutting mechanism have certain drawbacks during use. As the rubber roll is fed at a constant speed along the inside of the slitting machine, and there are angular contaminants on the surface of the rubber roll during the transfer, the contaminants or particulate impurities adhering to the roll will dull the blade edge during the continuous cutting operation of the circular blade, which may affect the sharpness of subsequent blade edges in severe cases.

[0004] In view of this, a multi-blade rubber slitting machine was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A multi-blade rubber slitting machine includes a slitting and pressure-bearing mechanism, a slitting mechanism mounted on the slitting and pressure-bearing mechanism, and multiple sets of blade anti-dulling mechanisms mounted within the slitting and pressure-bearing mechanism. The slitting and pressure-bearing mechanism includes a main pad and a secondary pad, with two beams installed between the main pad and the secondary pad. Two vertical rods are installed inside the main pad, and guide plates are fixedly installed on the two vertical rods. The slitting mechanism includes a machine housing mounted on a stud on the main pad, with a motor fixedly installed inside the machine housing. A main shaft is mounted on the motor, and multiple circular blades are fixedly installed on the main shaft. The blade anti-dulling mechanisms include an oil reservoir mounted on the two vertical rods, with two guide rods movably installed inside the oil reservoir. Brush pads are installed on the two guide rods, and tension springs are provided outside the guide rods.

[0007] In a preferred embodiment, the present invention can be further configured such that: the top of both the main pad and the secondary pad are fixedly mounted with vertical plates, and the main shaft is movably mounted within the two vertical plates.

[0008] In a preferred embodiment, this utility model can be further configured as follows: a hydraulic component is fixedly installed inside the secondary pad block; a main beam plate is movably installed on the two vertical rods; two horizontal rods are installed inside the main beam plate; a secondary beam plate is installed on the two horizontal rods; and the top end of the hydraulic sub-rod inside the hydraulic component is installed inside the secondary beam plate; and multiple evenly distributed pressure rollers are movably installed on the outside of the horizontal rods.

[0009] In a preferred embodiment, the present invention can be further configured such that: a cover plate and a sealing plate are respectively installed at both ends of the oil storage tank, and an oil pipe is installed inside the sealing plate.

[0010] In a preferred embodiment, the present invention can be further configured such that a positioning plate is fixedly installed in the middle of the top surface of the oil tank, and the shaft of the main shaft is movably installed in the positioning plate.

[0011] In a preferred embodiment, the present invention can be further configured as follows: a track frame is fixedly installed on the top of the oil storage tank, an insert plate is inserted into the track frame, a screw is threaded onto the insert plate, a support rod is snapped onto the inner end of the screw, and a scraper is fixedly installed on the support rod.

[0012] In a preferred embodiment, the present invention can be further configured such that a cotton brush is fixedly mounted on the scraper surface facing the circular blade.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model sets multiple sets of blade edge anti-dullness mechanisms evenly distributed at the bottom of multiple existing circular blades. As the multiple circular blades continue to rotate and pass through multiple sets of oil-soaked brush pads, the oil overflowing from the brush pads after being squeezed will remove the dirt remaining on the blades and provide rust protection for the blades. The oil remaining on the blades will be effectively cleared by the scraper, ensuring that the continuously rotating circular blades can efficiently cut the subsequently delivered rubber rolls.

[0014] 2. This utility model sets two symmetrically distributed crossbars directly above the guide plate, and installs multiple evenly distributed pressure rollers on the crossbars. A gap adapted to a circular blade is reserved between two adjacent pressure rollers. As the multiple pressure rollers press the rubber roll down onto the upper surface of the guide plate, the roll with multiple points of pressure can be accurately cut, avoiding the problem of irregular cuts caused by the roll being deformed under pressure.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-blade rubber slitting machine.

[0020] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a multi-blade rubber slitting machine, including a slitting and pressure bearing mechanism 100, a slitting mechanism 200 installed on the slitting and pressure bearing mechanism 100, and multiple sets of blade anti-dulling mechanisms 300 installed in the slitting and pressure bearing mechanism 100. The slitting mechanism 200 is used to slit the delivered and compressed rubber roll, and the blade anti-dulling mechanisms 300 are used to protect the blades in the slitting mechanism 200 from dulling.

[0021] The slitting and pressure bearing mechanism 100 includes a main pad 110 and a secondary pad 1101, and two beams 1103 are installed between the main pad 110 and the secondary pad 1101. Two vertical rods 1102 are installed inside the main pad 110, and guide plates 160 are fixedly installed on the two vertical rods 1102. Vertical plates 150 are fixedly installed on the top of both the main pad 110 and the secondary pad 1101. The slicing mechanism 200 includes a housing 210 mounted on a stud on a main pad block 110. A motor 220 is fixedly installed inside the housing 210. A spindle 2201 is mounted on the motor 220. Multiple circular blades 230 are fixedly mounted on the spindle 2201. The spindle 2201 is movably mounted inside two vertical plates 150. The blade blunt prevention mechanism 300 includes an oil reservoir 310 mounted on two vertical rods 1102. Two guide rods 330 are movably installed inside the oil reservoir 310, and brush pads 3302 are mounted on the two guide rods 330. Tension springs 3301 are provided outside the guide rods 330. A cover plate 3101 and a sealing plate 3102 are respectively installed at both ends of the oil reservoir 310. An oil pipe 320 is installed inside the sealing plate 3102. A positioning plate 31 is fixedly installed in the middle of the top surface of the oil reservoir 310. 03, and the shaft of the main shaft 2201 is movably installed in the positioning plate 3103. The top of the oil tank 310 is fixedly installed with a track frame 340. A plate 3401 is inserted into the track frame 340. A screw 3402 is threaded into the plate 3401. A support rod 3403 is snapped into the inner end of the screw 3402. A scraper 3404 is fixedly installed on the support rod 3403. A cotton brush is fixedly installed on the scraper 3404 facing the plate surface of the circular blade 230.

[0022] Preferably, the two beams 1103 are rectangular in structure, and multiple sets of oil storage tanks 310 are evenly distributed and welded to the top of the two beams 1103. The rod segment of the main shaft 2201 is movably installed in the two vertical plates 150 through two bearings. The multiple evenly distributed circular blades 230 are located directly below the groove in the middle of the guide plate 160, and the cutting edge of the top of the circular blades 230 is higher than the upper surface of the guide plate 160. In addition, the chassis 210 is inserted into the two studs of the main pad 110, and the chassis 210 inserted into the two studs is locked and fixed by two nuts; When the motor 220 starts and drives the main shaft 2201 to rotate at high speed, the evenly distributed circular blades 230 will rotate stably along the groove in the middle of the guide plate 160. As the hydraulic component 120 runs, its internal hydraulic rod drives the sub-beam plate 1301 and the two crossbars 1302 to descend. The evenly distributed pressure rollers 140 will press down on the rubber roll until the rubber roll and the multiple circular blades 230 achieve rapid and efficient cutting. After the cutting edge of the circular blades 230 passes through the two brush pads 3302, the squeezed brush pads 3302 will quickly remove the dirt on the blade surface of the circular blades 230.

[0023] Example 2: Combination Figure 2 and Figure 5 As shown, in the above embodiment, a hydraulic component 120 is fixedly installed inside the auxiliary pad block 1101, a main beam plate 130 is movably installed on the two vertical rods 1102, two horizontal rods 1302 are installed inside the main beam plate 130, an auxiliary beam plate 1301 is installed on the two horizontal rods 1302, and the top end of the hydraulic sub-rod inside the hydraulic component 120 is installed inside the auxiliary beam plate 1301. Multiple evenly distributed pressure rollers 140 are movably installed on the outside of the horizontal rods 1302.

[0024] Preferably, the pressure roller 140 is made of stainless steel and the outer surface of the pressure roller 140 is a smooth coating. The gap reserved between two adjacent pressure rollers 140 is used to guide the cutting edge of the circular blade 230, ensuring that the circular blade 230 will not wobble abnormally due to the compression of the roll material after it passes through the roll material.

[0025] The working principle and usage process of this utility model are as follows: When in use, the rubber material to be cut is delivered along one end of the guide plate 160 by the feeding device. After the rubber material is laid flat on the top surface of the guide plate 160, the hydraulic component 120 is operated until the hydraulic rod inside the hydraulic component 120 retracts and drives the sub-beam plate 1301, crossbar 1302 and main beam plate 130 to descend. Meanwhile, the multiple pressure rollers 140 installed outside the crossbar 1302 descend and cooperate with the guide plate 160 to stabilize and press the two sides of the area where the rubber material is to be cut. Meanwhile, the motor 220 is started via the cloud, and the internal drive shaft of the motor 220, in conjunction with the main shaft 2201, drives multiple evenly distributed circular blades 230 to rotate at high speed. The rubber material, pressed down by multiple pressure rollers 140, is quickly cut by the evenly distributed circular blades 230. After the circular blades 230 rotate once, the two sides of the inner edge of the circular blades 230 pass along the inner sides of the two adjacent brush pads 3302. When the two brush pads 3302, which are soaked in oil, are squeezed by the circular blades 230, the oil is evenly applied to both sides of the edge. As the circular blades 230 continue to rotate, the two evenly distributed scrapers 3404 scrape off the oil remaining on the surface of the circular blades 230. The scraped oil flows back along the gaps inside the two cover plates 3101, ensuring that the edge of the circular blades 230 is clean while avoiding excessive oil contact with the rubber material.
