Abstract
Description
Technical Field
[0001] This application relates to the field of plastic product technology, and in particular to a multi-angle adjustable holder for a color difference detection rack for plastic products. Background Technology
[0002] Plastic products are various products made from high molecular polymers as the main raw material, with the addition of various additives, and processed through injection molding, extrusion, blow molding and other processes. They are widely used in many fields such as electronics, automobile manufacturing, household goods, and medical devices. The appearance quality of these products, especially the color consistency, directly affects consumers' willingness to buy and the market competitiveness of the products. Therefore, it is crucial to conduct strict color difference testing on plastic products during the production process. In the color difference testing process, it is necessary to use a carrier frame to stably support the plastic products to ensure that the testing equipment can accurately collect the color information of the product surface, providing a reliable basis for subsequent color difference analysis and judgment.
[0003] Currently, the racks used for color difference testing of plastic products lack effective fixing structures. They can only simply place plastic products and cannot securely fix them according to different shapes and sizes. During the testing process, the products are easily displaced by slight external vibrations or testing operations, causing the testing position to shift and affecting the accuracy of the color difference test results. On the other hand, existing racks are usually designed with a fixed angle and cannot achieve multi-angle adjustment. Since plastic products have complex structures such as curved surfaces and sloping surfaces, fixed-angle racks make it difficult for the testing equipment to comprehensively test all parts of the product from different angles, easily leading to blind spots and reducing the efficiency of inspection. Therefore, to solve the above problems, we provide a multi-angle adjustable bracket for color difference testing racks of plastic products. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-angle adjustable holder for color difference detection of plastic products, so as to solve the problems mentioned in the background art.
[0005] The embodiments of this application adopt the following technical solutions:
[0006] A multi-angle adjustable holder for color difference detection of plastic products includes a support plate, a drive cover fixedly installed on one side of the support plate, a positioning component provided on one side of the support plate, a support cover located below the positioning component, a reduction motor fixedly installed on the inner bottom wall of the support cover, a rotating shaft fixedly installed at the output end of the reduction motor, the top end of the rotating shaft fixedly connected to the bottom surface of the positioning component, a variable frequency motor fixedly installed on one side of the drive cover, a worm gear fixedly installed at the output end of the variable frequency motor, a rotating block fixedly connected to the bottom surface of the support cover, a transmission rod fixedly connected to the inner ring of the rotating block, and a worm wheel fixedly installed at one end of the transmission rod.
[0007] Preferably, the positioning component includes a support slide fixedly mounted on the top of the rotating shaft, a dual-head motor fixedly mounted on the inner wall of the support slide, transmission screws fixedly mounted on both output ends of the dual-head motor, and threaded transmission blocks threadedly connected to the outer surfaces of the two transmission screws.
[0008] Preferably, each of the two threaded transmission blocks has a positioning plate fixedly connected to its top end. Both positioning plates are located above the support slide. The upper surface of the support slide has two sliding holes, and the outer surfaces of the two threaded transmission blocks are slidably connected to the inner walls of the two sliding holes respectively.
[0009] Preferably, a bearing ring is fixedly embedded on one side of the support plate, the inner ring of the bearing ring is fixedly connected to the outer surface of the transmission rod, and two bearing rings are fixedly embedded in the inner wall of the drive cover, with the inner rings of both bearing rings being fixedly connected to the outer surfaces of both ends of the worm gear.
[0010] Preferably, the bottom end of the worm gear meshes with the outer surface of the worm, and both the worm gear and the worm are located inside the drive cover.
[0011] Preferably, the bottom surface of the support plate is fixedly connected to a fixed base, and the upper surface of the fixed base is provided with two sets of fixing holes.
[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:
[0013] 1. This plastic product color difference detection carrier has a multi-angle adjustable bracket. It uses a double-headed motor to drive the transmission screw to rotate. With the help of the threaded connection between the threaded transmission block and the transmission screw, and the sliding engagement of the threaded transmission block along the sliding hole, it can quickly drive the two positioning plates to move relative to each other and clamp the product. It can be adapted to plastic products of different shapes and sizes, avoids product displacement caused by external vibration or operation during testing, solves the problem of test result deviation caused by position offset, and improves the accuracy of plastic product color difference detection.
[0014] II. The multi-angle adjustable bracket for color difference detection of plastic products uses a geared motor to drive the rotating shaft and positioning components to rotate, enabling multi-angle adjustment of the plastic product in the horizontal direction. This facilitates the detection equipment to detect different positions of the product in the horizontal direction. When it is necessary to detect plastic products with complex structures such as curved surfaces and inclined surfaces, the variable frequency motor is started. Through the meshing transmission of the worm gear and worm wheel, the transmission rod, rotating block and support cover can be tilted, thereby tilting the plastic product on the positioning components to the required angle. This solves the problem that fixed-angle brackets cannot detect complex structure products and improves the effect of color difference detection of plastic products. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0023] Please see Figure 1-4 This utility model provides a multi-angle adjustable bracket for color difference detection of plastic products:
[0024] A multi-angle adjustable bracket for color difference detection of plastic products includes a support plate 1, a drive cover 2 fixedly mounted on one side of the support plate 1, a positioning component 3 disposed on one side of the support plate 1, a support cover 4 disposed below the positioning component 3, a reduction motor 5 fixedly mounted on the inner bottom wall of the support cover 4, a rotating shaft 6 fixedly mounted on the output end of the reduction motor 5, the top end of the rotating shaft 6 fixedly connected to the bottom surface of the positioning component 3, a variable frequency motor 13 fixedly mounted on one side of the drive cover 2, and a worm gear fixedly mounted on the output end of the variable frequency motor 13. A rotating block 8 is fixedly connected to the bottom surface of the support cover 4 and the inner ring of the rotating block 8 is fixedly connected to the transmission rod 7. A worm gear 10 is fixedly installed at one end of the transmission rod 7. Specifically, the rotating shaft 6 is driven to rotate by the reduction motor 5, which in turn drives the positioning component 3 and the plastic product above to rotate horizontally to meet the requirements for adjusting the horizontal detection angle. The worm gear 11 is driven to rotate by the frequency conversion motor 13, which enables the worm gear 11 to mesh with the worm gear 10, so that the transmission rod 7 drives the rotating block 8 and the support cover 4 to tilt, thereby realizing the adjustment of the tilt angle of the plastic product.
[0025] In this embodiment, the positioning component 3 includes a support slide 36 fixedly mounted on the top of the rotating shaft 6. A dual-head motor 31 is fixedly mounted on the inner wall of the support slide 36. A transmission screw 32 is fixedly mounted on each of the two output ends of the dual-head motor 31. A threaded transmission block 33 is threadedly connected to the outer surface of each of the two transmission screws 32. A positioning plate 35 is fixedly connected to the top of each of the two threaded transmission blocks 33. The two positioning plates 35 are located above the support slide 36. Two sliding holes 34 are opened on the upper surface of the support slide 36. The outer surfaces of the two threaded transmission blocks 33 are slidably connected to the inner walls of the two sliding holes 34 respectively. Specifically, when the dual-head motor 31 is started, it can drive the two transmission screws 32 to rotate synchronously. Since the threaded transmission blocks 33 are threadedly connected to the transmission screws 32 and can slide along the sliding holes 34 of the support slide 36, the rotation of the transmission screws 32 will cause the two threaded transmission blocks 33 to move relative to each other, thereby causing the positioning plates 35 to clamp plastic products of different sizes and shapes, thus preventing product displacement during testing.
[0026] In this embodiment, a bearing ring 9 is fixedly embedded on one side of the support plate 1. The inner ring of the bearing ring 9 is fixedly connected to the outer surface of the transmission rod 7. Two bearing rings 12 are fixedly embedded in the inner wall of the drive cover 2. The inner rings of the two bearing rings 12 are fixedly connected to the outer surfaces of both ends of the worm 11. The bottom end of the worm wheel 10 meshes with the outer surface of the worm 11. The worm wheel 10 and the worm 11 are both located inside the drive cover 2. A fixed base 14 is fixedly connected to the bottom surface of the support plate 1. Two sets of fixing holes 15 are opened on the upper surface of the fixed base 14. Specifically, the bearing ring 9 on the support plate 1 reduces the friction when the transmission rod 7 rotates. The two bearing rings 12 inside the drive cover 2 can stabilize the rotation trajectory of the worm 11 and ensure accurate transmission. The fixed base 14 at the bottom of the support plate 1 can stably place or install the card seat on the testing platform. The two sets of fixing holes 15 on its surface facilitate the firm fixing of the card seat by bolts and other components, avoiding the overall displacement of the card seat during the testing process.
[0027] Working principle: First, the plastic product to be tested is placed on the support slide 36. Then, the double-headed motor 31 on the inner wall of the support slide 36 is started. The two output ends of the double-headed motor 31 will drive the transmission screw 32 to rotate synchronously. Since the threaded transmission block 33 is threadedly connected to the transmission screw 32, and the threaded transmission block 33 slides with the support slide 36 through the sliding hole 34, the rotation of the transmission screw 32 will be converted into the relative movement of the two threaded transmission blocks 33 along the sliding hole 34, which in turn drives the positioning plate 35 at the top to clamp the plastic product, avoiding product displacement due to vibration or operation during testing, and ensuring accurate testing position.
[0028] After the product is fixed, the reduction motor 5 on the inner bottom wall of the support cover 4 is started. The output end of the reduction motor 5 will drive the rotating shaft 6 to rotate. The rotating shaft 6 is fixedly connected to the bottom surface of the positioning component 3. Therefore, the rotation of the rotating shaft 6 will directly drive the positioning component 3 and the clamped plastic product to rotate horizontally, realizing multi-angle adjustment in the horizontal direction. If the tilt angle needs to be adjusted, the frequency conversion motor 13 on one side of the drive cover 2 is started. The output end of the frequency conversion motor 13 drives the worm gear 11 to rotate. The worm gear 11 meshes with the worm wheel 10 at one end of the transmission rod 7. The rotation of the worm gear 11 will drive the worm wheel 10 and the transmission rod 7 to rotate, and then drive the support cover 4, the positioning component 3 and the plastic product to tilt through the rotating block 8, meeting the detection needs of different parts of curved and inclined plastic products, ensuring that the detection equipment can comprehensively collect color information of all parts of the product, and improving the color difference detection effect.
