Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, in particular to a paint and coating detection device. Background Art

[0002] In the paint and coating industry, the fluidity of the paint is not only related to the aesthetics of the final coating film, but also directly affects the hiding power, glossiness and construction feel of the paint. Therefore, the detection of the paint is of great significance to ensure the quality of the paint and improve the quality of coating. The existing paint detection generally adopts the tilted test plate method or the tilted funnel method, applying a certain amount of paint to the test plate or funnel, and measuring the volume or distance of flow per unit time to evaluate the fluidity of the paint. However, there are still some problems in the use of the existing paint detection device, as follows:

[0003] The existing paint detection device cannot perform fluidity detection on multiple paints at different inclinations at the same time, and can only perform fluidity detection on a single paint at a fixed inclination at a time, which greatly limits the use of the device. In addition, the existing detection device cannot intuitively reflect the paint that needs to be compared during the detection process, and requires subsequent measurement of the volume of the paint flow or weight bearing, which greatly reduces the use efficiency of the device. For this reason, we propose a paint and coating detection device. Summary of the invention

All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0031] See also Figure 1-3A paint and coating detection device comprises an outer shell 1, a bottom column 2 is fixedly installed at the inner bottom end of the outer shell 1, a cross bar 3 is movably installed inside the bottom column 2, and a collection box 4 is fixedly installed at both ends of the cross bar 3, a locking groove 5 is opened on the outer shell 1, a column 6 is fixedly installed at the top of the bottom column 2, an external drive motor is fixedly installed at the top of the outer shell 1, and a driving gear 7 is fixedly installed on the output shaft of the external drive motor, a positioning ring 8 is fixedly installed at the inner top end of the outer shell 1, a rotation control component 9 is movably sleeved on the positioning ring 8, a paint containing funnel 10 is fixedly installed at the end of the rotation control component 9, a rotation adjustment component 11 is fixedly installed on the column 6, and a limit horizontal plate 12 is fixedly installed on the column 6;

[0032] Compared with the prior art, the present application provides two pairs of collecting boxes 4, and the two pairs of collecting boxes 4 are rotatably arranged on the bottom column 2 through the cross bar 3, so that the paint in the corresponding paint containing funnel 10 above will directly fall into the collecting box 4 during the downward flow, so that the collecting boxes 4 on both sides can intuitively reflect the flow and fall of the paint according to the falling amount of the paint. The collecting box 4 with paint with good fluidity at one end will be pressed down, while the other side will be tilted up, and because it is synchronously controlled by the driving gear 7, it can ensure that the two paint containing funnels 10 can rotate at the same angle at the same time, thereby ensuring that the paint contained in the paint containing funnel 10 is not affected by other factors during the process of detecting fluidity, thereby ensuring the accuracy and reliability of the detection result, and at the same time, by arranging a rotation adjustment component 11 and a rotation control component 9 inside the outer shell 1, by controlling the disc 11 2 can drive the driven gear 93 to mesh or disengage with the driving gear 7, so that the rotation angle of a single paint holding funnel 10 can be controlled, and then the detection device can also independently perform fluidity detection of multiple paints with different requirements, which greatly increases the scope of application of the device. The pull rod 117 can be rotated relative to the bottom end of the straight rod 115 through the structural setting, so that the pull rod 117 can be stuck on the outer shell 1 after moving downward, thereby ensuring that the disc 112 can continue to apply force to the driven gear 93, thereby ensuring that the plug plate 95 can be stably inserted in the positioning ring 8, so that after adjusting the rotation angle of one paint holding funnel 10, the angle of the remaining paint holding funnels 10 can be adjusted by rotating the driving gear 7, so that the angle adjustment between each driving gear 7 is independent of each other, reflecting the control performance of the device.

[0033] See also Figure 1-3 A paint coating detection device includes a cross bar 3, the number of the cross bars 3 is two and the two cross bars 3 are vertically staggered with each other, the middle part of the cross bar 3 is movably installed inside the bottom column 2 through a pin shaft, and the collection box 4 is arranged below the paint containing funnel 10, and the paint containing funnel 10 can be provided with a paint lining;

[0034] In this embodiment, it should be noted that the fallen paint can be received by the collecting boxes 4 symmetrical on both sides at the same time, so that the fluidity detection and comparison of the paint to be compared can be intuitively performed, and the collecting box 4 on the side with good paint fluidity will sink, so that the comparison can be achieved directly during the detection process, and the fluidity detection of the paint can be performed separately on each collecting box 4 through the regulation of the rotating control component 9 and the rotating adjustment component 11, which greatly improves the applicability of the device. At the same time, the paint lining can ensure that each paint will not stick to the paint containing funnel 10 and affect the subsequent detection of other paints, thereby improving the convenience of use of the device.

[0035] See also Figure 1-3 A paint and coating detection device includes a locking groove 5, which is in an inverted T-shape and is located in the middle of an outer shell 1. The locking groove 5 is located on all four vertical surfaces of the outer shell 1. A rotation adjustment component 11 is movably arranged in the locking groove 5, and a driving gear 7 and a rotation control component 9 are detachably engaged and movably arranged;

[0036] In this embodiment, it should be noted that the rotation control component 9 can be regulated to disengage from the drive gear 7 by moving the rotation adjustment component 11 downward in the locking groove 5. After the rotation control component 9 is disengaged from the drive gear 7, the bottom end of the rotation adjustment component 11 is rotated to engage the lateral part at the bottom of the locking groove 5. In this way, the rotation angle of the paint containing funnel 10 corresponding to the current rotation adjustment component 11 can be locked. In this way, four paint containing funnels 10 can be rotated at the same angle at the same time, and a single single angle rotation can also be achieved, which greatly improves the flexibility of use of the device.

[0037] See also Figure 1-6 A paint and coating detection device includes a positioning ring 8, which is fixedly installed above the inner wall side of an outer shell 1, and a densely annular slot is opened on the side of the positioning ring 8 located inside the outer shell 1, a rotation control component 9 is movably connected to the positioning ring 8 through a bearing, and a rotation adjustment component 11 is movably arranged through a limit horizontal plate 12;

[0038] In this embodiment, it should be noted that the angle of the paint containing funnel 10 at the end of the rotating control component 9 can be adjusted by rotating the rotating control component 9 on the positioning ring 8, and when the adjustment is completed, the angle can be locked by disengaging the rotating control component 9 from the engagement with the drive gear 7, or by locking the rotating control component 9 through an external drive motor. The rotating control component 9 is locked by plugging into the slot on the positioning ring 8, thereby ensuring the flexible adjustability of the tilt angle of the paint containing funnel 10.

[0039] See also Figure 3-9A paint and coating detection device includes a rotation control component 9, the rotation control component 9 includes an outer rod 91, one end of the outer rod 91 is provided with a groove and a first spring 92 is fixedly installed inside the groove, one end of the outer rod 91 is movably provided with a connecting rod and the end of the connecting rod is fixed with a driven gear 93, an insert rod 94 is movably installed on the driven gear 93, and an insert plate 95 is fixedly installed at the end of the insert rod 94;

[0040] In this embodiment, it should be noted that one end of the first spring 92 is in contact with one end of the connecting rod, and the side of the connecting rod is symmetrically provided with convex strips, and corresponding long grooves are provided on both sides of the groove where the first spring 92 is installed in the outer rod 91, and the driven gear 93 and the driving gear 7 are detachably meshed. The number of the insertion rods 94 is four and each two are arranged in a group. The connecting line between each group of insertion rods 94 passes through the center of the circle of the driven gear 93. The insertion rod 94 is fixedly installed with a collar on the side of the driven gear 93 where the outer rod 91 is located, and a positioning rod is provided on the collar and is movably inserted into the driven gear 93. The other end of the insertion rod 94 extends to the outer side of the driven gear 93 on the other side. The insert plate 95 is arranged at an interval with the rotation adjustment component 11, and the insert plate 95 can be inserted into the slot of the positioning ring 8. In this way, when it is necessary to lock the angle of a single paint holding funnel 10, the insert plate 95 can be driven to be inserted into the slot of the positioning ring 8 through the control of the rotation adjustment component 11, so that the angle locking of the paint holding funnel 10 is initially achieved, and the driven gear 93 will be pushed in the direction of the outer rod 91 subsequently, so that the driven gear 93 is separated from the driving gear 7, so that the subsequent rotation of the driving gear 7 will not drive the currently disengaged driven gear 93, thereby ensuring that the device can realize the angle adjustment control of a single paint holding funnel 10.

[0041] See also Figure 3-10 A paint and coating detection device includes a rotating adjustment component 11, the rotating adjustment component 11 includes a telescopic rod 111, a disc 112 is fixedly installed at one end of the telescopic rod 111, an adapter block 113 is fixedly installed on one side of the disc 112, a stop block 114 is movably provided on the adapter block 113, a straight rod 115 is fixedly installed at the bottom end of the stop block 114, a second spring 116 is movably sleeved on the straight rod 115, a pull rod 117 is movably installed at the bottom end of the straight rod 115, and a ring magnet 118 is embedded and installed on the disc 112;

[0042] In this embodiment, it should be noted that the other end of the telescopic rod 111 is fixedly mounted on the side of the column 6, the adapter block 113 is a right-angled trapezoidal structure and the vertical straight edge is fixedly mounted in the middle of the disc 112, a through groove is provided in the middle of the adapter block 113, and the straight rod 115 is movably arranged in the through groove, and positioning grooves are symmetrically provided on both sides of the through groove on the inclined surface of the adapter block 113, the stop block 114 is also provided with an inclined surface and the inclined surface is slidably arranged in the inclined surface of the adapter block 113, and a roller is movably arranged in the positioning groove on the inclined surface of the stop block 114, a retaining ring is provided on the top of the second spring 116 on the straight rod 115, the straight rod 115 is movably arranged through the limiting horizontal plate 12, the bottom end of the second spring 116 is arranged in contact with the upper surface of the limiting horizontal plate 12, and the pull rod 117 is at the bottom end of the straight rod 115 It is a rotating connection method, the pull rod 117 is movably arranged in the locking groove 5, and the ring magnet 118 is arranged corresponding to the position of the insertion rod 94, so that when adjusting and controlling the angle locking of a single paint holding funnel 10, the pull rod 117 can be pulled downward, thereby causing the stop block 114 to move downward, so that the adapter block 113 can be pushed to drive the disc 112 to move toward the insertion rod 94, so that the insertion rod 94 can be resisted to move toward the positioning ring 8, thereby causing the insertion plate 95 to be inserted into the positioning ring 8 and locked, and then the pull rod 117 is rotated to be clamped in the lateral part of the locking groove 5 to achieve the locking of the rotation adjustment component 11, and the locking of the rotation control component 9 is indirectly achieved, so that the paint holding funnel 10 can be locked, thereby ensuring that the device can achieve the angle adjustment of a single paint holding funnel 10.

[0043] Working principle: start the external drive motor, the external drive motor drives the driving gear 7 to rotate, and then the paint holding funnel 10 rotates and tilts at the same time, and then the paint to be tested is poured into each paint holding funnel 10 respectively. If the fluidity of two paints needs to be compared, the two paints can be placed in two paint holding funnels 10 on the opposite sides, and then the external drive motor drives the driving gear 7 to rotate, and the driving gear 7 will drive the insertion rod 94 to rotate, thereby driving the outer rod 91 to rotate, which also drives the paint holding funnel 10 to rotate to the angle where the paint can flow from the bottom to the collection box 4. According to the amount of flow per unit time, the paint on the side with good fluidity will cause the collection box 4 to sink, so that the flow of the two compared paints can be intuitively seen. The mobility is good or bad. When the angle of a single paint holding funnel 10 needs to be adjusted, the pull rod 117 can be pulled downward to the bottom end of the locking groove 5. The pull rod 117 will drive the block 114 to move downward, and then push the adapter block 113 and the disc 112 laterally. The disc 112 will resist the insertion rod 94 and extend from the other end of the driven gear 93 to the slot of the positioning ring 8. When the insertion plate 95 is inserted into the slot, the driven gear 93 will be separated from the driving gear 7 under the push of the disc 112, and then the pull rod 117 is rotated to lock the horizontal part at the bottom of the locking groove 5. In this way, the angle of the current paint holding funnel 10 can be locked, and then the external drive motor can be started to adjust the angle of the remaining paint holding funnels 10.
