Description

Technical Field

[0001] This utility model relates to auxiliary facilities for photovoltaic glass calendering and forming production, specifically to a device for measuring the runout of photovoltaic glass calendering rolls. Background Technology

[0002] With the increasing attention paid to the development of solar energy, solar photovoltaic glass is also gaining more and more attention. Improving the quality of photovoltaic glass has become the goal of manufacturers. For photovoltaic glass produced by calendering, the quality control of calendering rolls has become even more critical.

[0003] For the quality of calender rolls, their runout is a crucial core indicator, serving as the fundamental guarantee for controlling the consistency of glass sheet thickness. Runout refers to the degree to which different points on the outer curved surface of the calender roll deviate from the roll axis when it rotates after being installed on the calender mill. A larger runout indicates greater dispersion, resulting in poorer glass sheet thickness consistency; excessive runout can directly lead to product rejection. Conversely, a smaller runout indicates better thickness consistency and higher glass sheet quality. Previously, runout tests were conducted on calender rolls before putting them into operation. If the runout did not meet requirements, the rolls needed to be removed and reprocessed, requiring replacement with new rolls. Given the large size and weight of calender rolls, installation and removal are extremely difficult. Therefore, finding a more convenient testing method is an urgent matter. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides a device for measuring the runout of photovoltaic glass calendering rolls.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for measuring the runout of a photovoltaic glass calendering roll includes a calendering roll support structure, which includes two rotor seats symmetrically arranged at the two ends of the calendering roll. Two sets of mounting grooves are spaced apart on the rotor seats, each groove containing a rotor whose rotation axis is parallel to the rotation axis of the calendering roll. During measurement, the calendering roll head is placed between the two rotors and simultaneously rolls with both rotors.

[0007] The measuring structure includes a measuring chassis and a measuring instrument mounted on the measuring chassis. The measuring instrument has measuring terminals; during measurement, the measuring terminals make contact with the roll surface of the calendering roll.

[0008] Furthermore, the rotor base includes a base plate, and two longitudinal upright plates and two transverse upright plates fixedly disposed on the base plate;

[0009] The upper ends of the two longitudinal uprights are each provided with two arc-shaped grooves spaced apart along the front-to-back direction. The two arc-shaped grooves on the left and right sides cooperate to form a set of mounting grooves.

[0010] Furthermore, a liner is provided inside the arc-shaped groove.

[0011] Furthermore, the rotor includes a rotating shaft, on which an outer bushing is fitted, and a bearing is installed between the outer bushing and the rotating shaft; both ends of the rotating shaft are placed in corresponding arc-shaped grooves of the rotor seat.

[0012] Furthermore, positioning rings are fixedly provided at both ends of the bushing on the rotating shaft, and the positioning rings abut against the inner ring of the bearing.

[0013] Furthermore, positioning heads are fixed at both ends of the rotating shaft, and the diameter of the positioning heads is larger than that of the rotating shaft.

[0014] Furthermore, the outer bushing is made of nylon or polytetrafluoroethylene.

[0015] Furthermore, the measuring chassis is provided with a magnetic base that magnetically engages with it, and a vertical rod is fixed on the magnetic base, with the measuring instrument mounted on the vertical rod.

[0016] Furthermore, the measuring instrument is a dial indicator, which is equipped with an adjustment sleeve. The adjustment sleeve is fitted onto the upright and fixed by a locking screw passing through the adjustment sleeve.

[0017] Furthermore, it also includes a level detection structure for detecting the horizontal state of the two rotor seats, the level detection structure including a level plate and a level gauge.

[0018] The beneficial effects of this utility model are:

[0019] 1. By applying this utility model, it is not necessary to install the calender rolls on the calendering machine. Instead, the runout of the calender rolls can be conveniently measured before they are installed on the machine, reducing many unnecessary intermediate steps and a significant amount of labor. This utility model can also provide cutting data support for the reprocessing of calender rolls.

[0020] 2. In this utility model, the measuring instrument can be adjusted and mounted on the upright, and the upright is mounted on the magnetic base. The magnetic base and the measuring chassis are magnetically attracted to each other, so that the position of the measuring instrument can be adjusted as needed, which facilitates the measurement of data of the calender roll.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1 to 6 As shown, this embodiment provides a photovoltaic glass calender roll runout measurement device, including a calender roll support structure and a measurement structure 3.

[0031] The calender roll support structure includes two rotor seats 2, which are symmetrically arranged at the two ends of the calender roll 6 at the roll head 601. Two sets of mounting slots are spaced apart on the rotor seats 2, and each mounting slot houses a rotor 1. The rotation axis of the rotor 1 is parallel to the rotation axis of the calender roll 6. During measurement, the roll head 601 of the calender roll 6 is placed between the two rotors 1 and simultaneously rolls with both rotors 1, allowing the calender roll to rotate on it while being protected.

[0032] In this embodiment, the rotor base 2 includes a base plate 201, and two transverse upright plates 202 and two longitudinal upright plates 203 fixedly disposed on the base plate. The upper ends of the two longitudinal upright plates 203 are provided with two arc-shaped grooves 204 spaced apart along the front-back direction. Each arc-shaped groove 204 is lined with a rubber pad 205. The two arc-shaped grooves on the left and right sides cooperate to form a set of mounting slots, and a rotor is installed in the set of mounting slots.

[0033] In this embodiment, the rotor 1 includes a rotating shaft 102, an outer bushing 104 is fitted on the rotating shaft 102, and a bearing 103 is installed between the outer bushing 104 and the rotating shaft. Positioning rings 105 are fixedly provided on the rotating shaft 102 at both ends of the bushing, and the positioning rings 105 abut against the inner rings of the bearings.

[0034] The outer bushing 104 is made of materials such as nylon or polytetrafluoroethylene, which have a certain hardness but will not damage the metal shaft end. The rotor shaft 102 is made of 10~20mm steel column.

[0035] Positioning heads 101 are fixed at both ends of the rotating shaft 102, and the diameter of the positioning heads 101 is larger than that of the rotating shaft 102. During assembly, the two ends of the rotating shaft 102 are placed in the corresponding arc-shaped grooves 204 of the rotor seat. At this time, the positioning heads 101 are located outside the longitudinal vertical plate 203, which can prevent the rotor from falling off.

[0036] The measuring structure 3 includes a measuring chassis 304, a magnetic base 302, a vertical rod 303, and a dial indicator 304. An adjusting sleeve is fixedly mounted on the dial indicator 304, which is fitted onto the vertical rod 303 and is adjustablely fixed to the vertical rod 303 by a locking screw passing through the adjusting sleeve. The vertical rod 303 is fixedly mounted on the magnetic base 302, which magnetically engages with the measuring chassis 304. The dial indicator 304 has dial indicator measuring terminals 305, which contact the surface of the calendering roll 6 during measurement to perform data measurement and display.

[0037] With the above settings, the position of the dial indicator measuring terminal 305 can be adjusted as needed to facilitate the measurement of runout data of the calender roll.

[0038] It also includes a level detection structure for detecting the horizontal state of the two rotor seats 2, the level detection structure including a level plate 5 and a level 4.

[0039] The assembly and use process of this utility model is as follows:

[0040] (1) Assembly of the calender roll support structure: The bearing 103 is fitted onto the rotating shaft 102, and the outer bushing 104 is fixed to the outside of the bearing 103 by tight fit or adhesive. A positioning ring 105 is added on each side, and the outermost positioning heads 101 on both sides are fixed to the rotating shaft 102 by screws, thus completing the rotor assembly. The rotor seat 2 is welded, the liner 205 is placed in the arc-shaped groove 204, and the two assembled rotors are installed on the rotor seat 2 to form the calender roll support structure.

[0041] (2) Assembly of the measuring structure: Install the upright 303 on the magnetic base 302, fix the dial indicator 304 on the upright 303, the measuring terminals of the dial indicator are made of agate material, and attach the magnetic base 302 to the measuring chassis 301.

[0042] (3) Measurement: Place the two rotor seats 2 in the correct positions according to the length of the calender roll 6, place the level plate 5 on the two rotor seats 2, and then place the level 4 on the level plate 5. Observe the bubble on the level 4 and adjust it to be roughly in the middle. Then remove the level 4 and the level plate 5, place the calender roll 6 on the two rotor seats 2, remove the packaging on the calender roll 6, so that the calender roll 6 can rotate on the assembly unit.

[0043] Place the measuring structure 3 on one side of the calender roll 6 as specified. Adjust the height of the dial indicator 304 to a suitable position, and then adjust the measuring terminal 305 of the dial indicator to make it elastically contact the calender roll 6, while maintaining a certain margin. Adjust the pointer of the dial indicator to point to zero. Rotate the calender roll 6 at least one revolution and observe the change in the pointer. The maximum amplitude value is the runout of the calender roll. Then, according to the specified procedure, measure and record the data at both ends, the middle, or a specific location.

[0044] This invention enables the testing of the runout of calender rolls before they are put into operation, which greatly reduces labor intensity and saves unnecessary replacement time. It can also provide cutting data support for the reprocessing of calender rolls after use.
