Description

Technical Field

[0001] This utility model relates to the field of coating testing technology, specifically a weathering resistance testing device for coating production. Background Technology

[0002] Weathering test equipment for coating production is a specialized device used to simulate various climatic conditions in the natural environment to test the durability and stability of coatings. It conducts accelerated aging tests on coating samples by simulating factors such as sunlight, temperature changes, and humidity, thereby evaluating the performance of coatings in the long-term exposure to the natural environment in a short period of time. For example, a common ultraviolet resistance device places the sample on a mesh tray and then uses an ultraviolet lamp to continuously irradiate the sample.

[0003] However, traditional ultraviolet weathering equipment can only irradiate one side of the sample and cannot adjust the sample angle during irradiation, resulting in poor functionality. In addition, ultraviolet lamps are usually fixed, which makes the light source direction relatively singular, resulting in a large amount of light source waste and low utilization rate of ultraviolet light. Therefore, a weathering test equipment for coating production is needed to solve the existing shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a weather resistance testing device for coating production. Through the set control mechanism, the ultraviolet lamp can only perform weather resistance testing on the sample surface. When the sample is in a vertical state, it can perform weather resistance testing on both sides of the sample. Through the set drive mechanism, the ultraviolet lamp can irradiate the sample from all angles during the sample rotation process, thereby improving the utilization rate of ultraviolet light.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a weathering resistance testing device for coating production, comprising a test cylinder, a support plate fixedly connected to the bottom end of the test cylinder, a support rod rotatably connected to the top end of the support plate, a mounting frame fixedly connected to the top end of the support rod, a set of symmetrical guide cylinders movably connected to the top end of the mounting frame, a movable cylinder movably connected to the front end of the guide cylinders, and a clamping plate fixedly connected to the front end of each movable cylinder, a control mechanism provided inside the mounting frame and connected to the guide cylinders, a suspension movably connected inside the test cylinder, several mounting holes for installing ultraviolet lamps provided on the suspension, a driving mechanism provided at the bottom end of the test cylinder, one end of the driving mechanism fixedly connected to the bottom end of the suspension, and the other end of the driving mechanism fixedly connected to the bottom end of the support rod.

[0006] The present invention is further configured such that the control mechanism includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a rotating rod. The first synchronous pulley and the second synchronous pulley are symmetrically arranged. The first synchronous pulley is fixedly connected to the outside of the guide cylinder. The rotating rod passes through the second synchronous pulley and is fixedly connected to the second synchronous pulley. A synchronous belt is sleeved on the outside of adjacent first and second synchronous pulleys, and the first synchronous pulley, the second synchronous pulley, and the synchronous belt constitute a belt drive structure.

[0007] The present invention is further configured such that the mounting bracket includes a vertical part and a horizontal part, the vertical part is symmetrically arranged at the top of the horizontal part, the first synchronous pulley, the synchronous belt and the guide cylinder are all movably arranged inside the vertical part, and the second synchronous pulley and the rotating rod are all movably arranged inside the horizontal part.

[0008] The present invention is further configured such that a servo motor is fixedly connected to the outer side of the transverse portion, and the output end of the servo motor is fixedly connected to the end of the rotary rod.

[0009] The present invention is further configured such that a connecting block is movably connected inside the guide cylinder, and multiple protruding ends of the connecting block are fixedly connected to the inner side of the movable cylinder. An adjusting rod is movably connected inside the guide cylinder, and the outer side of the adjusting rod is threaded. The adjusting rod passes through the connecting block and is threadedly connected to the connecting block.

[0010] The present invention is further configured such that the driving mechanism includes a gear ring, a first gear, a second gear, a third synchronous pulley, a fourth synchronous pulley, and a control belt. The first gear meshes with the gear ring, and the first gear meshes with the second gear. The first gear and the second gear are both movably connected to the bottom end of the test cylinder via a rotating shaft. The third synchronous pulley is fixedly connected to the bottom end of the rotating shaft of the second gear, and the fourth synchronous pulley is fixedly connected to the bottom end of the support rod. The control belt is sleeved on the outside of the third synchronous pulley and the fourth synchronous pulley, and the third synchronous pulley, the fourth synchronous pulley, and the control belt constitute a belt drive structure.

[0011] The present invention is further configured such that the top end of the toothed ring is fixedly connected to the bottom end of the suspension, the outer side of the support plate is movably connected to the inner side of the bottom end of the suspension, and the bottom end of the test cylinder is fixedly connected to a second servo motor, and the output end of the second servo motor is fixedly connected to the bottom end of the support rod.

[0012] Compared with existing technologies, this weathering test equipment for coating production has the following advantages:

[0013] 1. This utility model, through its control mechanism, controls the rotation of the synchronous wheel and guide cylinder under the action of the synchronous belt, thereby controlling the clamping plate to drive the sample to rotate. The clamping angle of the sample can be adjusted, which helps to collect the light tolerance of the sample at different angles and improves the functionality of the ultraviolet tolerance equipment. When the sample is in a horizontal state, the ultraviolet lamp can only perform tolerance testing on the sample surface. When the sample is in a vertical state, tolerance testing can be performed on both sides of the sample.

[0014] 2. This utility model uses a drive mechanism to rotate the support rod and the four synchronous pulleys. Under the action of the control belt, the three synchronous pulleys and the two gears rotate in the same direction, thereby controlling the first gear to rotate in the opposite direction. Since the first gear meshes with the gear ring, the rotation direction of the support rod and the gear ring, i.e. the sample rotation direction, is opposite to the suspension rotation direction. This allows the ultraviolet lamp to irradiate the sample from all angles during the sample rotation process, improving the utilization rate of ultraviolet light. Attached Figure Description

[0022] 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.

[0023] like Figure 1-6 As shown, this utility model provides a technical solution: a weathering resistance testing device for paint production, including a test cylinder 1. A support plate 2 is fixedly connected to the bottom end of the test cylinder 1, and a support rod 3 is rotatably connected to the top end of the support plate 2. A mounting frame 4 is fixedly connected to the top end of the support rod 3. A set of symmetrical guide cylinders 5 are movably connected to the top end of the mounting frame 4. A movable cylinder 6 is movably connected to the front end of the guide cylinder 5, and a clamping plate 7 is fixedly connected to the front end of each movable cylinder 6. The clamping plate 7 is concave to facilitate the insertion of the sample edge. A control mechanism 8 is provided inside the mounting frame 4 and is connected to the guide cylinder 5. The interior of the test cylinder 1... The device is connected by a suspension 9, which has several mounting holes 10 for installing ultraviolet lamps. A drive mechanism 11 is provided at the bottom of the test cylinder 1. One end of the drive mechanism 11 is fixedly connected to the bottom of the suspension 9, and the other end of the drive mechanism 11 is fixedly connected to the bottom of the support rod 3. The ultraviolet lamp is installed inside the suspension 9 through the mounting holes 10. The mounting holes 10 are made of transparent material to facilitate the diffusion of ultraviolet light. The test cylinder 1 is cylindrical, and a reflective cloth can be installed on the inner wall of the test cylinder 1 to help reflect ultraviolet light to the axis of the test cylinder 1, thereby increasing the amount of light received by the sample and improving the utilization rate of ultraviolet light.

[0024] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the control mechanism 8 includes a first synchronous pulley 801, a second synchronous pulley 802, a synchronous belt 803, and a rotating rod 804. The first synchronous pulley 801 and the second synchronous pulley 802 are symmetrically arranged. The first synchronous pulley 801 is fixedly connected to the outside of the guide cylinder 5. The rotating rod 804 passes through the second synchronous pulley 802 and is fixedly connected to the second synchronous pulley 802. A synchronous belt 803 is fitted onto the outside of adjacent first synchronous pulleys 801 and second synchronous pulleys 802. Together with the synchronous belt 803, they form a belt drive structure. The mounting frame 4 includes a vertical part 12 and a horizontal part 13. The vertical part 12 is symmetrically arranged at the top of the horizontal part 13. The synchronous pulley 801, the synchronous belt 803 and the guide cylinder 5 are all movably arranged inside the vertical part 12. The synchronous pulley 802 and the rotating rod 804 are both movably arranged inside the horizontal part 13. The servo motor 14 is fixedly connected to the outside of the horizontal part 13, and the output end of the servo motor 14 is fixedly connected to the end of the rotating rod 804.

[0025] Servo motor 14 drives the rotating rod 804 and the synchronous pulley 802 to rotate in the horizontal part 13 of the mounting frame 4. Under the action of the synchronous belt 803, it controls the synchronous pulley 801 and the guide cylinder 5 to rotate, thereby controlling the clamping plate 7 to drive the sample to rotate. The clamping angle of the sample can be adjusted, which helps to collect the light tolerance of the sample at different angles and improves the functionality of the ultraviolet tolerance equipment. When the sample is in a horizontal state, the ultraviolet lamp can only perform tolerance testing on the sample surface. When the sample is in a vertical state, tolerance testing can be performed on both sides of the sample.

[0026] like Figure 1 and Figure 5 As shown, a connecting block 15 is movably connected inside the guide cylinder 5. Multiple protruding ends of the connecting block 15 are fixedly connected to the inner side of the moving cylinder 6. An adjusting rod 16 is movably connected inside the guide cylinder 5. The adjusting rod 16 has a thread on its outer side. The adjusting rod 16 passes through the connecting block 15 and is threadedly connected to the connecting block 15. When the adjusting rod 16 is rotated, since the adjusting rod 16 is threadedly connected to the connecting block 15 and the guide cylinder 5 restricts the movement direction of the connecting block 15, the moving cylinder 6 is driven to move forward along the outer side of the guide cylinder 5, so that the clamping plate 7 moves closer to the sample, thereby clamping samples of different sizes through the two clamping plates 7.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the drive mechanism 11 includes a gear ring 1101, a first gear 1102, a second gear 1103, a third synchronous pulley 1104, a fourth synchronous pulley 1105, and a control belt 1106. The first gear 1102 meshes with the gear ring 1101, and also meshes with the second gear 1103. Both the first gear 1102 and the second gear 1103 are movably connected to the bottom end of the test cylinder 1 via rotating shafts. The third synchronous pulley 1104 is fixedly connected to the bottom end of the rotating shaft of the second gear 1103. The fourth synchronous pulley 1105... The control belt 1106 is fixedly connected to the bottom end of the support rod 3 and sleeved on the outside of the synchronous pulley 3 1104 and the synchronous pulley 4 1105. The synchronous pulley 3 1104, the synchronous pulley 4 1105 and the control belt 1106 constitute a belt drive structure. The top end of the toothed ring 1101 is fixedly connected to the bottom end of the suspension 9. The outside of the support plate 2 is movably connected to the inside of the bottom end of the suspension 9. The bottom end of the test cylinder 1 is fixedly connected to the servo motor 2 17, and the output end of the servo motor 2 17 is fixedly connected to the bottom end of the support rod 3.

[0028] Start the servo motor 17 to drive the support rod 3 to rotate at the top of the support plate 2, thereby controlling the mounting frame 4 to drive the sample to rotate. The support rod 3 and the synchronous wheel 1105 rotate. Under the action of the control belt 1106, the synchronous wheel 1104 and the gear 1103 rotate in the same direction, thereby controlling the gear 1102 to rotate in the opposite direction. Since the gear 1102 meshes with the gear ring 1101, the support rod 3 and the gear ring 1101 rotate in opposite directions. That is, the sample rotation direction is opposite to the suspension 9 rotation direction, so that the ultraviolet lamp irradiates the sample from all angles during the sample rotation, improving the utilization rate of ultraviolet light.

[0029] Working principle: In use, the sample is placed on the opposite side of the clamping plate 7, which is concave to facilitate the edge of the sample being engaged. Then, the adjusting rod 16 is rotated. Since the adjusting rod 16 is threadedly connected to the connecting block 15, and the guide cylinder 5 restricts the movement direction of the connecting block 15, the moving cylinder 6 is driven to move forward along the outside of the guide cylinder 5, causing the clamping plate 7 to move closer to the sample. Thus, samples of different sizes are clamped by the two clamping plates 7. Subsequently, the servo motor 14 drives the rotating rod 804 and the synchronous pulley 802 to rotate in the transverse part 13 of the mounting frame 4. Under the action of the synchronous belt 803, the synchronous pulley 801 and the guide cylinder 5 are controlled to rotate, thereby controlling the rotation of the sample. The clamping plate 7 drives the sample to rotate, and the clamping angle of the sample can be adjusted. The servo motor 17 is started, which drives the support rod 3 to rotate at the top of the support plate 2, thereby controlling the mounting frame 4 to drive the sample to rotate. The support rod 3 and the synchronous wheel 1105 rotate. Under the action of the control belt 1106, the synchronous wheel 1104 and the gear 1103 rotate in the same direction, thereby controlling the gear 1102 to rotate in the opposite direction. Since the gear 1102 meshes with the gear ring 1101, the support rod 3 and the gear ring 1101 rotate in opposite directions. That is, the sample rotation direction is opposite to the suspension 9 rotation direction, so that the ultraviolet lamp irradiates the sample at all angles during the sample rotation.
