Description

Technical Field

[0001] The utility model relates to the technical field of coating machines and coating machine accessories, in particular to a spacing measuring device. Background Art

[0002] An air flotation oven generally includes an upper nozzle arranged at the top and a lower nozzle arranged at the bottom. Both the upper nozzle and the lower nozzle include multiple nozzles arranged in parallel and spaced apart. The nozzles on the upper nozzle and the lower nozzle are staggered in the horizontal direction. The spacing between the upper nozzle and the lower nozzle is mainly guaranteed by the three-dimensional model during design. However, the errors generated during the production and assembly process are immeasurable, and there is no direct tool to measure the finished product. It can only be inferred by indirectly measuring other points. Although ordinary ovens with low requirements (such as small test lines, single-sided coating supported by rollers, etc.) can allow for large errors, they will cause defects such as pole piece vibration, slurry on the pole piece to produce ripples, and the upper nozzle needs to provide a larger air volume to suppress the pole piece. Therefore, it is necessary to measure the actual gap between the upper nozzle and the lower nozzle in order to adjust the gap between the two.

[0003] A depth gauge is usually used to measure the gap. However, since the distance between the upper and lower nozzles is the actual distance when the upper and lower parts of the oven are completely closed, existing depth gauges are difficult to measure in the completely enclosed space of the oven. Utility Model Content

[0004] The utility model provides a spacing measuring device, which solves the technical problem that the existing depth gauge is difficult to measure in a completely enclosed space of an oven.

[0005] In view of this, the present invention provides a spacing measuring device, which is used to measure the upper and lower spacing between the upper nozzle and the lower nozzle of an air flotation oven. The spacing measuring device includes:

[0007] A ruler body is arranged on the bottom plate in a vertical direction;

[0008] A measuring piece, slidably connected to the ruler body, for cooperating with the ruler body to read the measurement distance;

[0009] A sliding rod is slidably arranged on the bottom plate in a vertical direction and is connected to the measuring piece. The sliding rod is used to abut against the upper air nozzle and slide along with the upper air nozzle.

[0010] Optionally, a base is provided at one end of the ruler body connected to the base plate, and the base is detachably connected to the base plate via a connecting assembly.

[0011] Optionally, the connection assembly includes a fixing frame and a plurality of fixing rods;

[0012] The fixing frame is detachably connected to the bottom plate, and the base is located inside the fixing frame;

[0014] Optionally, a positioning groove is provided on the bottom plate corresponding to the base, and the base is adapted to be embedded in the positioning groove.

[0015] Optionally, a levelness detection member is provided on the bottom plate for detecting the levelness of the lower air nozzle.

[0020] Optionally, the limiting member is a limiting screw, and the limiting screw is threadedly connected to the end surface of the sliding rod along the axial direction of the sliding rod.

[0021] The technical solution of this utility model has the following advantages:

The plate-like structure of the bottom plate is arranged so that it can be kept horizontal when placed on the upper surface of the air nozzle, that is, the measuring piece can be measured along the normal of the plane where the upper surface of the lower air nozzle is located to ensure the accuracy of the measurement.

[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1

[0036] See also Figures 1 to 5 The present embodiment provides a spacing measuring device, which is used to measure the upper and lower spacing between the upper and lower air nozzles 1 of an air flotation oven. The spacing measuring device includes: a base plate 2, which is horizontally arranged on the lower air nozzle 1; a ruler body 3, which is vertically arranged on the base plate 2; a measuring piece 4, which is slidably connected to the ruler body 3 and is used to cooperate with the ruler body 3 to read the measured spacing; a sliding rod 5, which is slidably provided on the base plate 2 in the vertical direction and is connected to the measuring piece 4. The sliding rod 5 is used to abut the upper air nozzle and slide with the upper air nozzle.

[0037] In this embodiment, when it is necessary to measure the upper and lower air nozzles 1, the bottom plate 2 is crossed over the two adjacent air nozzles on the lower air nozzle 1. The length of the bottom plate 2 can be determined according to the distance between the two adjacent air nozzles of the two lower air nozzles 1. At the same time, the ruler body 3 and the measuring piece 4 are set downward, and the end of the slide bar 5 away from the measuring piece 4 is set upward; during measurement, the air nozzle on the upper air nozzle moves downward and abuts against the top surface of the slide bar 5, and drives the slide bar 5 to move downward with the upper air nozzle. At the same time, the slide bar 5 drives the measuring piece 4 to slide downward on the ruler body 3 until the upper air nozzle reaches the predetermined working position. At this time, the measurement of the upper and lower gaps between the upper and lower air nozzles 1 is completed. After the upper air nozzle is controlled to move upward, the distance measuring component is taken out, and the measured distance can be read through the measuring piece 4, so that the measurement of the upper and lower gaps between the upper and lower air nozzles 1 can be completed in a confined space. The spacing measuring device provided in this embodiment spans the two adjacent air nozzles of the lower air nozzle 1 through the base plate 2, which meets the measurement needs when the lateral span of the two adjacent air nozzles is large, and has a wide range of applications. The plate-like structure of the base plate 2 can be adapted to the upper surface of the air nozzle, so that when the base plate 2 is overlapped on the upper surface of the air nozzle, the contact surfaces of the two can be parallel and fitted, increasing the contact area, making it convenient for the base plate 2 to remain horizontal when placed on the upper surface of the air nozzle, that is, the measuring piece 4 can be measured along the normal of the plane where the upper surface of the lower air nozzle 1 is located to ensure the accuracy of the measurement. The plate-like structure of the base plate 2 is also more stable when cooperating with the air nozzle, avoiding offset when the upper air nozzle abuts the slide rod 5 and moves, thereby affecting the measurement accuracy. In addition, the upper and lower gaps between the upper and lower air nozzles 1 can be measured in a sealed space, which has high flexibility and improves the measurement accuracy.

Then, the locking screw can be tightened to make it abut and lock the fixing rod 82 to prevent the fixing rod 82 from moving, so as to fix the base 11 on the base plate 2. Conversely, when disassembling, the locking screw can be loosened to keep it away from the fixing rod 82 and then the fixing rod 82 can be slid out to remove the base 11, which is convenient for installation and disassembly and can achieve quick assembly.

[0043] Specifically, an opening for the sliding rod 5 to pass through is provided on the base 11 corresponding to the through hole 10 , so that the sliding rod 5 can pass through the bottom plate 2 and the base 11 in sequence and be connected to the measuring piece 4 .

[0059] In this embodiment, by setting a limiter 7, the limiter 7 can be used to abut against the bottom plate 2 for limiting the position of the slide rod 5 during its movement, thereby preventing the measuring piece 4 from slipping out of the ruler body 3 due to excessive sliding distance, and the limiter 7 can abut against the upper nozzle.
