Description

Technical Field

[0001] The invention belongs to the technical field of roller production equipment, in particular to a base wheel cleaning device for a polyurethane roller. Background Art

[0002] Trolley wheels are common rollers in people's daily lives. They are generally divided into directional wheels and outward-directed wheels. Polyurethane rollers are generally popular due to their excellent properties such as being not easy to scratch, low noise, pollution-free, and having a wide range of applicable temperatures. Existing polyurethane rollers are divided into base wheels and polyurethane coatings. The base wheel is generally made of metal, and the outer surface of the base wheel is coated with polyurethane glue.

[0003] Since the outer surface of the metal base wheel is relatively rough after production, it needs to be polished and then cleaned before applying polyurethane glue. Since the base wheel needs to rotate at high speed during cleaning and a large amount of metal chips will be attached to the outer surface of the base wheel, the metal chips on the outer surface can easily be thrown away due to centrifugal force when the base wheel is polished, causing environmental pollution problems, so improvements are needed.

[0008] Furthermore, there are two top grinding devices. The outer surface of the sliding motor is slidably connected to one side of the bottom of the inner wall of the docking top tube. The outer surface of the active tractor is fixedly connected to the inner cavity of the docking top tube. The outer surface of the side winding drum is fixedly connected to one end of the bottom of the docking top tube via a slot. The bottom end of the milling cutter rod extends to the outside of the docking top tube through a sliding groove. The top end of the water spray inner tube is fixedly connected to the inner wall of the docking top tube, and the bottom end of the water spray inner tube extends to the outside of the docking top tube. The top of the anchoring top tube is fixedly connected to the ceiling.

[0009] Furthermore, the storage device includes a storage cover, the top of the storage cover inner cavity is fixedly connected to a circulating water tank, the top of the circulating water tank inner cavity is fixedly connected to a guide nozzle, the guide nozzle can be bent by external force to control the direction of water spraying at its end portion, and the bottom of the storage cover inner cavity is evenly provided with through drainage ports. The axis of the lower surface of the storage cover is fixedly connected to the upper surface of the storage base, the upper surface of the side torque machine is slidably connected to the lower surface of the storage cover, the outer surface of the side torque machine output shaft is slidably connected to the inner cavity of the storage cover via a horizontal slide groove, and the bottom of the axis rotation machine output shaft is rotatably connected to the axis of the inner cavity of the storage cover.

[0010] Furthermore, the sleeve-type rotating rod includes a long shell, a hollow inner tube is fixedly connected to the axis of the inner cavity of the long shell, side spray plates are symmetrically fixed on the left and right sides of the inner cavity of the hollow inner tube, outer slides are symmetrically arranged on the left and right sides of the inner cavity of the long shell, and arc springs are symmetrically arranged on the front and back sides of the outer surface of the outer slide, the axis rotating machine can control the rotation of the long shell, and the sleeve-type rotating rod at the bottom is a hollow structure, which can control the pressure inside the hollow inner tube.

The bottom of the outer surface of the long shell is rotatably connected to the axis of the inner cavity of the storage top cover. The side of the arc spring away from the outer slide is fixedly connected to the inner wall of the long shell. The interior of the docking top tube is sleeved with the exterior of the long shell. The top end of the long shell is fixedly connected to a docking device, and the top of the inner cavity of the anchoring top tube is fixedly connected to a receiver at the axis.

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

[0013] 1. The device can grind the side and upper surface of the base wheel at the same time, and then use the water spray inner pipe to immediately wash away the debris generated by turning to achieve cleaning and cooling. Since the debris generated when the base wheel is performing milling on the outer surface will be washed away by the water, and the arc edge structure of the storage top cover can make it difficult for the water to splash to the outside, thereby ensuring that the base wheel inside the storage top cover will not pollute the external environment during processing, and the flushing water can also clean the inside of the storage top cover, so that the debris will not accumulate inside the storage top cover, causing the problem of clogging the drainage port.

[0014] 2. When the base wheel is milled and ground inside the device, the side grinding wheels on both sides rub the base wheel at the axis at the same time, balancing the extrusion force on the base wheel and avoiding eccentric movement of the base wheel during processing, which may cause damage during grinding. The side torque machines on both sides and the milling cutter rod 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 models, with high versatility.

[0015] 3. When the base wheel is sleeved on the outer surface of the sleeve rotating rod, it can rotate synchronously with the sleeve rotating rod. Since the base wheel is deflected in the opposite direction to the side grinding wheels on both sides at this time, the base wheel will not slip with the side grinding wheels. In order to enable the sleeve rotating rod to tighten the base wheel, the sleeve rotating rod pushes the outer slide plate outward to open the inner wall of the base wheel, and drives the base wheels of different models to rotate synchronously through strong extrusion friction, thereby achieving the effect of fixing the base wheel without clamping the base wheel, thereby ensuring that there is no dead angle area caused by clamping at the cutting point of the milling cutter, and the cleaning work of the base wheel is also more comprehensive.

[0016] 4. Every time the anchoring top cylinder pushes the docking top cylinder to slide down, the receiver at the axis of the anchoring top cylinder will perform a detection with the docking device below, that is, the docking device transmits infrared rays and is received by the receiver. If the receiver can receive them smoothly, it means that the base wheel is sleeved on the axis position of the device, and the side grinding wheels on both sides can perform symmetrical grinding. If the receiver cannot receive the infrared signal normally, the base wheel may deviate from the axis position, and further correction work is required before grinding and cleaning work can be carried out, thereby avoiding the problem of damage to the base wheel due to operational problems.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.

[0026] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a base wheel cleaning device for a polyurethane roller, comprising a receiving device 1, a control device 2 is provided at the bottom of the receiving device 1, and an upper processing device 3 is provided on the upper part of the receiving device 1;

[0027] The control device 2 includes a accommodating base 21, the top of the inner wall of the accommodating base 21 is fixedly connected with a guide rail 26, the inner wall of the guide rail 26 is slidably connected with a side twisting machine 27, the outer surface of the output shaft of the side twisting machine 27 is fixedly connected with a side grinding wheel 28, and the lower surface of the side grinding wheel 28 does not contact the accommodating device 1 to avoid wear problems, the middle part of the inner cavity of the guide rail 26 is fixedly connected with an axis rotating machine 25, the top end of the output shaft of the axis rotating machine 25 is fixedly connected with a sleeve rotating rod 4, the axis center of the lower surface of the axis rotating machine 25 is fixedly connected with a connecting guide cylinder 24, the lower part of the guide rail 26 is provided with a sliding inner disk 22, and the side of the lower surface of the sliding inner disk 22 away from the axis center is fixedly connected with a spring slide cylinder 23;

[0028] The upper processing equipment 3 includes an anchoring top cylinder 31, which is divided into three parts: a fixed plate at the top, a vertically sliding telescopic cylinder in the middle, and a fixed plate at the bottom. Control slides 32 are evenly arranged at the bottom of the inner cavity of the anchoring top cylinder 31. The inner wall of the control slide 32 is slidably connected to a vertical propulsion rod, and the bottom end of the vertical propulsion rod is fixedly connected to a docking top cylinder 33. Water spray inner pipes 34 are symmetrically arranged on the front and rear sides of the inner wall of the docking top cylinder 33, and top grinding equipment 5 is symmetrically arranged on the left and right sides of the inner wall of the docking top cylinder 33.

[0029] The top grinding device 5 includes a sliding motor 51, and the bottom end of the output shaft of the sliding motor 51 is fixedly connected to the milling cutter rod 52. The sliding motor 51 can control the bottom milling cutter rod 52 to rotate at high speed. One side of the outer surface of the sliding motor 51 is fixedly connected to the side winding drum 53 through a cable, and the other side of the outer surface of the sliding motor 51 is fixedly connected to a thick pull rope 54. The end of the thick pull rope 54 away from the sliding motor 51 is fixedly connected to an active traction device 55. The thick pull rope 54 and the cable can be used to control the sliding motor 51 to perform directional sliding movement along the side of the docking top cylinder 33.

[0030] There are two top grinding devices 5. The outer surface of the sliding motor 51 is slidably connected to one side of the bottom of the inner wall of the docking top tube 33. The outer surface of the active tractor 55 is fixedly connected to the inner cavity of the docking top tube 33. The outer surface of the side winding drum 53 is fixedly connected to one end of the bottom of the docking top tube 33 via a slot. The bottom end of the milling cutter rod 52 extends to the outside of the docking top tube 33 through a sliding groove. The top of the water spray inner tube 34 is fixedly connected to the inner wall of the docking top tube 33, and the bottom end of the water spray inner tube 34 extends to the outside of the docking top tube 33. The top of the anchoring top tube 31 is fixedly connected to the ceiling.

[0031] When using this device to clean the base wheel, pull out the upper processing equipment 3 from the shaft at the top of the control device 2, and then sleeve the base wheel on the sleeve rotating rod 4 in the middle. At this time, the base wheel slides down to the lowest point along the sleeve rotating rod 4 under the action of gravity, and then the sleeve rotating rod 4 fixes the base wheel to complete the preparation work.

[0032] The side twisting machines 27 on both sides drive the side grinding wheels 28 to rotate at high speed, and then guide the pull rope inside the slide rail 26 to move the side twisting machines 27 toward the axis, so that the high-speed rotating side grinding wheels 28 contact the side of the base wheel to achieve the grinding effect. In order to ensure that the base wheel does not slip, the axis rotation machine 25 will also drive the base wheel to rotate through the sleeve rotating rod 4, that is, the side grinding wheels 28 on both sides rotate clockwise and the base wheel rotates counterclockwise.

[0033] When trimming the side of the base wheel, the upper processing equipment 3 located above also lowers the docking top cylinder 33 along the sleeve rotating rod 4 through the control slide 32, and the upper surface of the base wheel is milled by the top grinding equipment 5. Then, the water spray inner pipes 34 on the front and rear sides flush the base wheel from top to bottom, so that the debris and dust of the base wheel are collected into the interior of the accommodating equipment 1, and the base wheel and related grinding equipment are cooled to avoid thermal deformation problems.

[0034] The waste water after flushing will be collected at the bottom of the inner wall of the accommodating base 21 through the notch of the sliding inner disk 22. Due to the friction force of the milling cutter, the entire accommodating base 21 and the platform above it will vibrate continuously, thereby causing the sliding inner disk 22 to vibrate vertically in the vertical plane. Combined with the elastic force of the spring slide 23, the sliding inner disk 22 can completely shake the water on the upper surface to the bottom, thereby realizing the wastewater recovery.

[0035] Example 2, please refer to Figure 1-Figure 7The present invention provides a technical solution: based on Example 1, the storage device 1 includes a storage top cover 11, a circulating water tank 12 is fixedly connected to the top of the inner cavity of the storage top cover 11, a guide nozzle 13 is fixedly connected to the top of the inner cavity of the circulating water tank 12, and the guide nozzle 13 can be bent by external force to control the direction of water spraying at its end portion. The bottom of the inner cavity of the storage top cover 11 is evenly opened with through drainage ports 14. The axis of the lower surface of the storage top cover 11 is fixedly connected to the upper surface of the storage base 21, the upper surface of the side twisting machine 27 is slidably connected to the lower surface of the storage top cover 11, the outer surface of the output shaft of the side twisting machine 27 is slidably connected to the inner cavity of the storage top cover 11 through a horizontal slide groove, and the bottom of the output shaft of the axis rotating machine 25 is rotatably connected to the axis of the inner cavity of the storage top cover 11.

[0036] The sleeve rotating rod 4 includes a long shell 41, a hollow inner tube 42 is fixedly connected to the axis of the inner cavity of the long shell 41, side spray plates 43 are symmetrically fixed on the left and right sides of the inner cavity of the hollow inner tube 42, and outer slides 44 are symmetrically arranged on the left and right sides of the inner cavity of the long shell 41. Arc springs 45 are symmetrically arranged on the front and back sides of the outer surface of the outer slide 44. The axis rotating machine 25 can control the rotation of the long shell 41, and the sleeve rotating rod 4 at the bottom is a hollow structure, which can control the pressure inside the hollow inner tube 42.

[0037] The outer surface of the outer slide 44 is slidably connected to the inner cavity of the long shell 41 via a groove, and the inner wall of the outer slide 44 is slidably connected to the outer surface of the side spray plate 43. The top end of the hollow inner tube 42 is fixedly connected to the axis 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 to the top of the inner cavity of the axis rotating machine 25. The bottom of the outer surface of the long shell 41 is rotationally connected to the axis of the inner cavity of the storage top cover 11. The side of the arc spring 45 away from the outer slide 44 is fixedly connected to the inner wall of the long shell 41. The interior of the docking top tube 33 is sleeved with the exterior of the long shell 41. The top end of the long shell 41 is fixedly connected to the docking device 36, and the top of the inner cavity of the anchoring top tube 31 is fixedly connected to the receiver 35 at the axis.

[0038] Since the water spraying inner tube 34 sprays water from top to bottom, its cleaning range is limited, so it is necessary to cooperate with the guide nozzle 13 on the storage top cover 11 to spray water from the side of the base plate at the axis to eliminate the dead angle of the water spraying, and the sprayed water will be blocked by the curved surface of the storage top cover 11, and thus cannot splash to the outside. The water penetrates downward through the through drainage port 14, and the through 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 connecting guide cylinder 24 will pressurize the interior of the hollow inner tube 42 through the hollow shaft of the axial rotating machine 25, so that the outer slides 44 on both sides slide toward the outside of the long shell 41 under the pressure of the side spray plates 43, and then squeeze with the inner wall of the base wheel, thereby jamming the base wheel and enabling the long shell 41 to drive the base wheel to rotate. After the work is completed, the hollow inner tube 42 is depressurized, so that the outer slides 44 that slide outward are retracted to the inside of the long shell 41 under the tension of the internal arc spring 45, and then the processed base wheel is pulled out along the sleeve rotating rod 4 to realize the unloading work.

[0040] Every time the anchoring top cylinder 31 pushes the docking top cylinder 33 to slide down, the receiver 35 at the axis of the anchoring top cylinder 31 will perform a detection with the docking device 36 below, that is, the docking device 36 emits infrared rays and is received by the receiver 35. If the receiver 35 can receive it smoothly, it means that the base wheel is sleeved at the axis position of the device, and the side grinding wheels 28 on both sides can perform symmetrical grinding work. If the receiver 35 cannot receive the infrared signal normally, the base wheel may be offset from the axis position, and further correction work is required before grinding and cleaning work can be carried out.

[0041] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
