TECHNICAL FIELD

[0001] The application belongs to the technical field of roller production equipment, and particularly relates to a base wheel cleaning device for a polyurethane roller. BACKGROUND

[0002] The trolley wheel is a common roller in people's daily life, and the wheel is generally divided into a directional wheel and an outward wheel; the polyurethane roller is popular due to excellent characteristics such as difficulty in scratching, small noise, no pollution and wide application temperature range, and the existing polyurethane roller is a base wheel and polyurethane rubber coating, and the base wheel is generally made of metal and coated with polyurethane rubber on the outer surface.

[0012] The beneficial effects of the present application are as follows:

[0013] 1. The device can simultaneously grind the side surface and the upper surface of the base wheel, then immediately flush away the chips generated during turning by using the water flushing inner tube to realize cleaning and cooling. Since the chips generated during the outer surface milling of the base wheel are flushed away by water, and the arc edge structure of the receiving top cover can prevent water from splashing outside, the base wheel inside the receiving top cover will not pollute the external environment during processing, and the flushing water can also flush the inside of the receiving top cover, so that the chips will not accumulate inside the receiving top cover to cause blockage of the through drainage port.

[0014] 2. When the base wheel is milled and polished inside the device, the two side edge grinding wheels simultaneously rub the base wheel at the axis to balance the extrusion force received by the base wheel, so as to avoid eccentric movement of the base wheel during processing, which can cause damage to the grinding. The side position twisting machine on both sides and the milling cutter bar above can slide and adjust according to the size of the base wheel, so that the device can process base wheels of different sizes, and has high universality.

[0015] 3. When the base wheel is sleeved on the outer surface of the sleeving rotating rod, it can rotate synchronously with the sleeving rotating rod. Since the base wheel is deflected in the opposite direction with the two side edge grinding wheels at this time, the base wheel will not slip with the side edge grinding wheels. In order to tightly fix the base wheel, the sleeving rotating rod pushes the outer sliding plate outward to expand the inner wall of the base wheel, and through strong extrusion friction, it drives different types of base wheels to rotate synchronously, so as to realize the fixing effect of the base wheel without clamping, so as to ensure that there is no dead angle area caused by clamping at the lower cutting point of the milling cutter, and the cleaning work of the base wheel is also more comprehensive.

[0016] 4.Each time the anchor top cylinder pushes the butt joint top cylinder down, the receiver at the center of the anchor top cylinder will detect the butt jointer below, that is, the infrared emitted by the butt jointer is received by the receiver. If the receiver can successfully receive, it means that the base wheel sleeve is at the center of the device, and the side edge grinding wheel on both sides can perform symmetrical grinding work. If the receiver cannot normally receive the infrared signal, the base wheel may be offset from the center position and needs to be corrected before grinding and cleaning work can be performed, thereby avoiding the problem of base wheel damage due to operation problems.

[0028] The upper processing device 3 comprises an anchoring top cylinder 31, the anchoring top cylinder 31 is divided into a fixed disc at the top, an expansion cylinder that can vertically slide at the middle, and a fixed disc at the bottom, the bottom of the inner cavity of the anchoring top cylinder 31 is uniformly provided with a control sliding cylinder 32, the inner wall of the control sliding cylinder 32 is slidably connected with a vertical pushing rod, and the bottom end of the vertical pushing rod is fixedly connected with a butt joint top cylinder 33, the front and back sides of the inner wall of the butt joint top cylinder 33 are symmetrically provided with water spraying inner pipes 34, and the left and right sides of the inner wall of the butt joint top cylinder 33 are symmetrically provided with top grinding devices 5.

[0029] The top grinding device 5 comprises a sliding motor 51, the bottom end of the output shaft of the sliding motor 51 is fixedly connected with a milling cutter rod 52, the sliding motor 51 can control the milling cutter rod 52 at the bottom to rotate at a high speed, one side of the outer surface of the sliding motor 51 is fixedly connected with a side position winding cylinder 53 through a cable, the other side of the outer surface of the sliding motor 51 is fixedly connected with a coarse pulling rope 54, and one end, away from the sliding motor 51, of the coarse pulling rope 54 is fixedly connected with a driving tractor 55, and the sliding motor 51 can be controlled to move directionally along the side edge part of the butt joint top cylinder 33 through the coarse pulling rope 54 and the cable.

[0030] The number of top grinding equipment 5 is two, the outer surface of sliding motor 51 is connected with one side of the bottom of the inner wall of butt joint top cylinder 33, the outer surface of driving tractor 55 is fixedly connected with the inner cavity of butt joint top cylinder 33, and the outer surface of side position winding cylinder 53 is fixedly connected with one end of the bottom of butt joint top cylinder 33 through a clamping groove. The bottom end of milling cutter rod 52 extends to the outside of butt joint top cylinder 33 through a sliding slot, the top end of water spraying inner tube 34 is fixedly connected with the inner wall of butt joint top cylinder 33, the bottom end of water spraying inner tube 34 extends to the outside of butt joint top cylinder 33, and the top of anchoring top cylinder 31 is fixedly connected with the ceiling.

[0031] When the device is used to clean the base wheel, the upper machining equipment 3 is pulled out from the shaft on the top of the control equipment 2, and then the base wheel is sleeved on the middle sleeving rotating rod 4. At this time, the base wheel slides to the lowest point under the action of gravity along the sleeving rotating rod 4, and then the sleeving rotating rod 4 fixes the base wheel, completing the preparation work.

[0032] The side edge grinding wheel 28 is driven by the side position twisting machine 27 on both sides to rotate at high speed, and then the pulling rope in the guide sliding rail 26 moves the side position twisting machine 27 to the direction close to the shaft center, so that the side edge grinding wheel 28 rotating at high speed contacts the side surface of the base wheel, achieving the polishing effect. In order to prevent the base wheel from slipping, the shaft center rotating machine 25 also drives the base wheel to rotate through the sleeving rotating rod 4, that is, the side edge grinding wheels 28 on both sides rotate clockwise, and the base wheel rotates counterclockwise.

[0033] When the side surface of the base wheel is trimmed, the upper machining equipment 3 located above also lowers the butt joint top cylinder 33 along the sleeving rotating rod 4 through the control sliding cylinder 32, mills the upper surface of the base wheel through the top grinding equipment 5, and then washes the base wheel from top to bottom through the water spraying inner tube 34 on the front and back sides, so that the chips and dust generated by turning the base wheel are collected in the container equipment 1, and the base wheel and the related polishing equipment are cooled to prevent thermal deformation.

[0034] The washed wastewater is collected in the position at the bottom of the inner wall of the containing base 21 through the cutting slot of the sliding inner disc 22. Due to the friction force of the milling cutter, the containing base 21 and the platform above continuously vibrate, causing the sliding inner disc 22 to vertically vibrate in the vertical plane. Combined with the elastic force of the spring sliding cylinder 23, the sliding inner disc 22 can completely shake off the water on the upper surface to the lower surface, thereby realizing the recycling of wastewater.

[0035] Embodiment 2, please refer to Figures 1-7The application provides a technical scheme: on the basis of embodiment 1, the containing device 1 comprises a receiving top cover 11, the top of the inner cavity of the receiving top cover 11 is fixedly connected with a circulating water conveying box 12, the top of the inner cavity of the circulating water conveying box 12 is fixedly connected with a guide spray pipe 13, the guide spray pipe 13 can be bent through external force, so that the direction of water spraying at the end part of the guide spray pipe 13 is controlled, and the bottom of the inner cavity of the receiving top cover 11 is uniformly provided with a penetrating drainage port 14. The shaft center of the lower surface of the receiving top cover 11 is fixedly connected with the upper surface of a containing base 21, the upper surface of a side position twisting machine 27 is slidingly connected with the lower surface of the receiving top cover 11, the outer surface of the output shaft of the side position twisting machine 27 is slidingly connected with the inner cavity of the receiving top cover 11 through a horizontal sliding groove, and the bottom of the output shaft of a shaft center rotating machine 25 is rotatably connected with the shaft center of the inner cavity of the receiving top cover 11.

[0036] The sleeve joint rotating rod 4 comprises a long shell 41, the shaft center of the inner cavity of the long shell 41 is fixedly connected with a hollow inner tube 42, the left and right sides of the inner cavity of the hollow inner tube 42 are symmetrically fixed with side position spray plates 43, the left and right sides of the inner cavity of the long shell 41 are symmetrically provided with outer sliding plates 44, the front and back sides of the outer surface of the outer sliding plate 44 are symmetrically provided with arc springs 45, the shaft center rotating machine 25 can control the rotation of the long shell 41, and the sleeve joint rotating rod 4 at the bottom is a hollow structure, so that the internal pressure of the hollow inner tube 42 can be controlled.

[0037] The outer surface of the outer sliding plate 44 is slidingly connected with the inner cavity of the long shell 41 through a cutting groove, the inner wall of the outer sliding plate 44 is slidingly connected with the outer surface of the side position spray plate 43, the top end of the hollow inner tube 42 is fixedly connected with the shaft center at the top of the inner cavity of the long shell 41, and the bottom end of the hollow inner tube 42 is fixedly connected with the top of the inner cavity of the shaft center rotating machine 25. The bottom of the outer surface of the long shell 41 is rotatably connected with the shaft center of the inner cavity of the receiving top cover 11, one side of the arc spring 45, away from the outer sliding plate 44, is fixedly connected with the inner wall of the long shell 41, the inside of the butt joint top cylinder 33 is sleeved with the outside of the long shell 41, the top end of the long shell 41 is fixedly connected with a butt joint device 36, and the shaft center at the top of the inner cavity of the anchoring top cylinder 31 is fixedly connected with a receiver 35.

[0038] Since the water spraying inner tube 34 sprays water from top to bottom, the cleaning range is limited, so the side position water spraying work on the base disc at the shaft center needs to be cooperated with the guide spray pipe 13 on the receiving top cover 11, the dead angle position of water spraying is eliminated, the sprayed water body is blocked by the arc surface of the receiving top cover 11, so it cannot splash to the outside, the water body penetrates downward through the penetrating drainage port 14, and the penetrating drainage port 14 has a large opening, so it will not be blocked by metal chips.

[0039] After the base wheel is sleeved at the bottom of the outer surface of the long shell 41, the communication guide cylinder 24 will pressurize the inside of the hollow inner tube 42 through the hollow shaft of the shaft center rotating machine 25, so that the outer sliding plates 44 on both sides slide outwards under the pressurization of the side position spray plate 43, and then extrude the inner wall of the base wheel, so as to clamp the base wheel, and the long shell 41 can drive the base wheel to rotate. After the work is completed, the outer sliding plates 44 that slide outwards are retracted into the long shell 41 under the pulling force of the internal arc-shaped spring 45, and then the finished base wheel is pulled out along the sleeved rotating rod 4 to realize the unloading work.

[0040] When the anchor top cylinder 31 pushes the butt joint top cylinder 33 to slide downwards each time, the receiver 35 at the shaft center of the anchor top cylinder 31 will detect the butt joint receiver 36 below once, that is, the infrared ray emitted by the butt joint receiver 36 is received by the receiver 35. If the receiver 35 can successfully receive, it means that the base wheel is sleeved at the shaft center position of the device, and the side edge grinding wheels 28 on both sides can perform symmetrical grinding work. If the receiver 35 cannot normally receive the infrared signal, the base wheel may be offset from the shaft center position, and needs to be corrected before grinding and cleaning work.

[0041] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by ordinary skilled in the art and related fields without creative labor should belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, such as without special description and limitation, are implemented according to the conventional means in the art.
