Description

Technical Field

[0001] The utility model relates to the field of conveyor roller calibration devices, and more specifically to a conveyor roller calibration support device. Background Art

[0002] During the production of ceramic tiles, a large number of roller conveyors are used to transport ceramic tile blanks and finished products to achieve semi-automatic and automated production. In actual use, due to factors such as high drying temperatures and long weighing and transportation, the rollers of some equipment will bend or deform to varying degrees, requiring calibration or replacement to ensure smooth overall transportation and guarantee product quality.

[0003] When calibrating and correcting such rollers, most factories currently place the rollers on a support structure, use straightened lines as a reference, and visually determine the location of unevenness in the rollers. Jacks are then used to apply force to the bent and deformed areas to restore them to the desired shape. This method has a simple overall structure and low cost, but requires staff to make judgments and calibrate based on visual inspection and experience, resulting in significantly lower efficiency and significant room for improvement in calibration quality.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 4 As shown, a specific embodiment of the present invention discloses a support device for calibrating a conveyor roller, including a support frame 100 and a detection structure 200 installed on the support frame 100; the support frame 100 includes two oppositely arranged support seats 110, and a frame plate 120 fixedly mounted between the two support seats 110; the support seats 110 are provided with a through hole 111 arranged along the length direction of the frame plate, and a pair of rollers 300 are rotatably installed on the outer sides of both ends of the through hole, and a rolling support portion is formed between the two rollers; the detection structure 200 is installed on one side of the frame plate 120, and the detection structure 200 includes a rotating shaft 210 extending along the length direction of the frame plate, and a plurality of closely arranged paddles 220 are rotatably installed on the rotating shaft 210, and the bottom of the paddle swings to the placement position of the workpiece to be inspected.

[0025] The above-mentioned support device for conveyor roller calibration, when the roller to be inspected is rotated, the bent and deformed part will lift up the corresponding paddle, distinguishing it from the other paddle positions, thereby indicating the bent part, and then correcting and adjusting it through the external jack; the overall structure is simple and novel, and can intuitively display the bent and deformed part of the roller, which is convenient for staff to perform calibration work and improve efficiency and calibration quality.

[0026] Furthermore, the bottom side wall of the support seat is provided with a flange, and the flange is provided with a through hole for fixing the support seat to the bottom surface; the two ends of the frame plate are welded and fixed between the two support seats, and the bottom surface of the frame plate is provided with an arc groove for adapting to the outer wall shape of the roller. When the jack is used to push and calibrate the bent part, the roller will be pushed toward the frame plate, and the roller will be blocked and held at the arc groove. Under the external force, the roller can be better restored to the desired shape;

[0027] Furthermore, four rollers are installed on a support seat, and two symmetrical third circular holes are provided on the outside of the support seat and the bottom of the perforation for passing the support shaft. The rollers are rotatably sleeved on the support shaft, thereby forming two sets of rolling support parts on the outside of the two ends of the perforation to provide rotational support for the roller rod to be tested, which is convenient for rotating the roller rod during detection and calibration, and for more comprehensive detection and adjustment.

[0028] Furthermore, if Figure 4 、 Figure 5 As shown, the detection structure 200 includes a pull frame 230, a rotating shaft 210, and a paddle 220; the pull frame 230 includes a frame rod 231, and L-shaped members 232 fixedly provided at both ends of one side of the frame rod. The L-shaped member extends outward, and the hook portion of the L-shaped member is bent downward. The hook portion is provided with a first circular hole 233 passing through both sides. The aperture of the first circular hole is adapted to the diameter of the rotating shaft. The rotating shaft 210 is rotatably provided between the two L-shaped members 232. Figure 3As shown, a guide groove 112 is provided on the wall surface of the support seat 110 close to the frame plate. The width of the guide groove 112 is adapted to the diameter of the rotating shaft 210; the spacing between the groove bottoms of the two guide grooves 112 is adapted to the length of the rotating shaft 210, and the spacing between the outer walls of the two L-shaped members 232 is adapted to the spacing between the inner walls of the two support seats 210; the rotating shaft 210 is movably clamped between the two guide grooves 112, and the two L-shaped members respectively press against the inner walls of the two support seats to slide; the paddles are rotatably installed on the rotating shaft, and the adjacent two paddles are movably pressed against each other; this structural design can adjust the position of the detection structure by dragging the pull frame, When assembling or removing the roller to be tested, this detection structure can be moved away to prevent it from affecting the normal placement of the roller to be tested; when testing is required, the detection structure is reset to the detection position and the corresponding operation is performed, which is simple to use and operate; since the rotating shaft and the pull frame are rotationally matched, the end of the rotating shaft and the guide groove are also movably matched, and the paddle and the rotating shaft are also rotationally matched, the position of the detection structure can be changed by pushing and pulling, rotating and pulling, or matching, which is convenient for adjustment operation; and the overall assembly structure is convenient for the processing and production of various structural components, the overall assembly, and the subsequent disassembly and replacement of parts.

[0029] Furthermore, the guide groove is open at one end away from the frame plate, and a stopper is provided on the outside of the open end, which is fixed to the support seat by screws, providing a position for the installation of the rotating shaft. The rotating shaft can be placed inward through the open end, and the rear end is blocked and prevented from falling off by the stopper, so that the detection structure installed on the support frame will not fall off or fall off; wherein, the length of the guide groove is sufficient for the detection structure to break away from the placement position of the roller rod to be inspected, at least when the detection structure moves to the point where the rotating shaft abuts against the stopper, the paddle breaks away from the placement position of the workpiece to be inspected, thereby preventing it from affecting the removal and placement of the roller rod to be inspected.

[0030] Furthermore, if Figure 6 As shown, a column 221 extending to both sides is fixedly provided on the middle and upper part of the paddle 220, and a second circular hole 222 is provided through both ends of the column 221 along the axial direction. The space of the second circular hole 222 is adapted to the diameter of the rotating shaft 210, and the paddle is rotatably installed on the rotating shaft through the second circular hole; the rotational matching position of the paddle and the rotating shaft is limited, so that the bottom of the paddle is heavier than the top, forming a natural drooping effect, which facilitates the paddles to be arranged side by side; further, the paddle is made of lightweight plastic or aluminum alloy to reduce its overall weight, so that the roller rod to be tested can lift the corresponding paddle during testing, so that the staff can carry out targeted calibration work.

[0031] Furthermore, a counterweight bar 223 is fixedly provided on the bottom surface of the paddle 220; the counterweight bar is fixedly adhered to the bottom surface of the paddle, and if the corresponding paddle itself is also made of metal material, it can also be fixed by welding, mainly to make the bottom of the paddle swing downward so that it can be reset to prepare for subsequent roller rod testing; it should be noted that the weight of the counterweight bar is relative to the paddle itself, and the weight of the counterweight bar and the paddle as a whole is still relatively light, which does not conflict with the above-mentioned reduction in overall weight and does not affect the push of the paddle by the roller rod to be tested.

[0032] Furthermore, the thickness of the pick is not less than 1 cm, and the color of the walls on both sides of the pick is different from the color of the other walls of the pick; preferably, colors with strong contrast are used, such as red / yellow / green / blue and other relatively conspicuous colors on both sides of the pick, while the other walls are white, to create a more obvious contrast, which is convenient for showing the uneven position of the roller rod and facilitating subsequent adjustments.

[0033] Furthermore, if Figure 4 、 Figure 5 As shown, a pressure plate 234 is fixedly provided at the bottom of both ends of the frame rod 231, and a magnet block 235 is fixedly embedded on the bottom surface of the pressure plate 234; the pull frame can be swung after adjustment until the pressure plate is against the top surface of the frame plate and is connected by magnetic attraction to adjust the position of the detection structure; the support seat and the frame plate are made of iron or magnetic stainless steel, and need to be magnetically connected with the magnet block of the detection structure to achieve the adjustment and locking of the pull frame position, so as to meet the requirements of positioning the pick at the detection position during detection; when removing the roller rod, the pick can be moved to other parts without affecting the placement and removal of the roller rod, which is convenient for the overall practical use and operation.

[0034] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
