Description

Technical Field

[0001] This application relates to the field of extruder screw detection technology, specifically a screw size measurement system. Background Technology

[0002] The main working principle of extruder materials is that after the raw materials are mixed and stirred by the screw, they need to be matched with different dies according to the requirements of the molded product to achieve extrusion molding. Because the screw will be subjected to material wear and corrosion during stirring, the size of the threaded element will change. Wear of the threaded element will directly affect the mixing effect, resulting in defective products.

[0003] However, after each cleaning of the screw, each dimension of the screw needs to be measured manually with calipers. Moreover, multiple dimensions of a single screw need to be measured manually, and each measurement requires manual operation of the calipers for positioning, reading, and other steps. The measurement process is cumbersome and time-consuming, which cannot meet the needs of rapid screw inspection in production, seriously affecting production efficiency and leading to extended production cycles.

[0004] Furthermore, manual measurement with calipers is difficult to perform comprehensively and accurately for some complex or hard-to-reach parts of the screw due to limitations in operating space and angle. This can easily lead to omissions in the inspection of some dimensions, resulting in an inability to fully grasp the actual wear of the screw and to detect potential problems in a timely manner, which in turn affects the normal operation of the extruder and the quality of the product. Utility Model Content

[0005] The purpose of this invention is to provide a screw size measurement system to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] A screw size measurement system includes a cleaning platform on which a drive assembly is mounted;

[0008] A screw, rotatably mounted on a cleaning platform, with one end of the screw keyed to a drive assembly;

[0009] A linear slide table, wherein a cleaning device is fixedly installed on the slide table;

[0010] The dimension detection component includes a mounting mechanism, two adjustment mechanisms, an industrial camera, and a light source assembly. The mounting mechanism is detachably mounted on the side wall of the cleaning device. The two adjustment mechanisms are slidably mounted on both sides of the mounting mechanism. The industrial camera is mounted on the bottom of one of the adjustment mechanisms, and the light source assembly is mounted on the bottom of the other adjustment mechanism to provide supplementary lighting for the industrial camera.

[0011] Preferably, the installation mechanism includes a connecting frame and a mounting frame. One side of the connecting frame is fixedly installed on the side wall of the cleaning device, and the top of the mounting frame is fixedly installed on the other side of the connecting frame. The mounting frame is in a "C" - shaped structure.

[0012] Preferably, the adjusting mechanism includes an adjusting frame, a screw rod, and a knob. A sliding groove is provided on the side wall of the adjusting frame. The bottom side walls on both sides of the mounting frame are fixedly connected to the screw rod. The adjusting frame is sleeved on the side wall of the screw rod through the sliding groove. The side wall of the screw rod is threadedly connected to the knob, and the outside of the adjusting frame abuts against the knob;

[0013] The bottom of the adjusting frame is fixedly installed with an industrial camera and a light source component respectively.

[0014] Preferably, limiting plates are integrally formed at the edges on both sides of the mounting frame, and both sides of the adjusting frame are slidably connected inside the limiting plates.

[0015] Preferably, the light source component includes a fixing frame and a supplementary light. The fixing frame is fixedly installed on the bottom of the adjusting frame, and both ends of the fixing frame are hinged to both sides of the supplementary light through bolts.

[0016] Preferably, a light - shielding cover is fixedly installed around the light source of the supplementary light. The light - shielding cover is in a frustum shape, and a reflecting mirror is installed on the inner surface of the light - shielding cover.

[0017] Preferably, the driving component includes a driving motor, a coupling, a rotating rod, a bearing seat, a universal joint, and a mounting sleeve. The driving motor and the bearing seat are both installed on one side of the top surface of the cleaning platform. The driving motor is fixedly installed with one end of the rotating rod through the coupling. The rotating rod is rotatably installed on the bearing seat. The other end of the rotating rod is fixedly installed with one end of the universal joint. The other end of the universal joint is fixedly installed with the mounting sleeve. One end of the screw rod is key - connected to the inside of the mounting sleeve.

[0018] The beneficial effects of this application are:

[0019] 1. Compared with manually measuring multiple dimensions of the screw rod one by one using a caliper, in this technical solution, the driving component drives the screw rod to rotate, and the linear slide table drives the cleaning device and the dimension detection component to move along the axial direction of the screw rod, enabling the screw rod to be dimension - measured by the dimension detection component. There is no need for cumbersome manual positioning and reading operations, shortening the measurement time of a single screw rod, meeting the requirement of rapid detection of screw rods in production, accelerating the production progress, effectively shortening the production cycle, and improving the overall production efficiency of the enterprise.

[0020] 2. In this technical solution, the drive assembly enables the screw to rotate 360°, and the linear slide moves the measuring assembly axially, allowing for comprehensive inspection of all parts of the screw without missing any dimensions. Simultaneously, the industrial camera and light source assembly work together to avoid the subjective errors of manual measurement and the limitations of caliper precision, accurately detecting subtle changes in screw dimensions, promptly identifying potential problems, ensuring the normal operation of the extruder, and ultimately guaranteeing product quality.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0038] Please see Figure 1-3 The embodiments provided by this utility model are as follows:

[0039] like Figure 1 As shown, the screw 6 size measurement system includes a cleaning platform 1, a drive assembly 2 is installed on the cleaning platform 1, the screw 6 is rotatably installed on the cleaning platform 1, and one end of the screw 6 is keyed to the drive assembly 2;

[0040] Specifically, such as Figure 3 As shown, the drive assembly 2 includes a drive motor 21, a coupling 22, a rotating rod 23, a bearing housing 24, a universal joint 25, and a mounting sleeve 26. The drive motor 21 and the bearing housing 24 are both mounted on one side of the top surface of the cleaning platform 1. The drive motor 21 is fixedly mounted to one end of the rotating rod 23 through the coupling 22. The rotating rod 23 is rotatably mounted on the bearing housing 24. The other end of the rotating rod 23 is fixedly mounted to one end of the universal joint 25. The other end of the universal joint 25 is fixedly mounted to the mounting sleeve 26. One end of the screw 6 is connected to the internal key of the mounting sleeve 26.

[0041] The cleaning platform 1 serves as the basic support structure of the entire system, providing a stable operating plane for the cleaning and measurement of the screw 6. After the drive motor 21 is powered on, it generates power, which is transmitted to the rotating rod 23 through the coupling 22. The rotating rod 23 achieves stable rotation under the support of the bearing seat 24, and then transmits the power to the mounting sleeve 26 through the universal joint 25. Since one end of the screw 6 is keyed to the inside of the mounting sleeve 26, it drives the screw 6 to rotate, enabling the screw 6 to rotate during the cleaning and measurement process, facilitating all-round cleaning and measurement, and improving the comprehensiveness and efficiency of cleaning and measurement.

[0042] like Figure 1As shown, a cleaning device 4 is fixedly installed on the slide table of the linear slide table 3. The linear slide table 3 drives the lead screw through a motor, causing the slide table to perform linear reciprocating motion on the linear guide rail. The linear slide table 3 is prior art known to those skilled in the art and will not be elaborated here. The cleaning device 4 is fixedly installed on the slide table of the linear slide table 3. As the slide table moves, the cleaning device 4 can move in the axial direction of the screw 6. During the movement, the cleaning device 4 cleans the surface of the screw 6, and the cleaning liquid is sprayed through the nozzles on the cleaning device 4 to remove dirt, impurities, etc. on the surface of the screw 6.

[0043] As Figure 1 and Figure 2 shown, after removing the dirt and impurities on the surface of the screw 6, an installation dimension detection component 5 is installed to measure the dimensions of the screw 6. The dimension detection component 5 includes an installation mechanism, two adjustment mechanisms, an industrial camera 7, and a light source component 8. The installation mechanism is detachably installed on the side wall of the cleaning device 4. The two adjustment mechanisms are respectively slidably installed on both sides of the installation mechanism. The industrial camera 7 is installed at the bottom of one of the adjustment mechanisms, and the light source component 8 is installed at the bottom of the other adjustment mechanism to provide supplementary light for the industrial camera 7.

[0044] Specifically, as Figure 2 shown, the installation mechanism includes a connecting frame 51 and an installation frame 52. One side of the connecting frame 51 is fixedly installed on the side wall of the cleaning device 4. The top of the installation frame 52 is fixedly installed on the other side of the connecting frame 51. The installation frame 52 is in a "C" - shaped structure. The connecting frame 51 fixedly connects the installation mechanism to the side wall of the cleaning device 4, acting as a bridge to install the installation frame 52 at a suitable position on the cleaning device 4. The installation frame 52 is in a "C" - shaped structure, providing an installation support platform for the adjustment mechanism, the industrial camera 7, and the light source component 8. The installation mechanism realizes the connection and fixation of the dimension detection component 5 to the cleaning device 4, ensuring the stability of the dimension detection component 5 during the measurement process, and at the same time providing an installation basis for the industrial camera 7 and the light source component 8 to ensure that they can be located on both sides of the screw 6 to be detected.

[0045] As Figure 2 shown, in order to be able to adjust the positions of the industrial camera 7 and the light source component 8 on both sides of the screw 6, the adjustment mechanism includes an adjustment frame 56, a screw rod 53, and a knob 54. A chute 57 is opened on the side wall of the adjustment frame 56. Both bottom side walls of the two sides of the installation frame 52 are fixedly connected to the screw rod 53. The adjustment frame 56 is sleeved on the side wall of the screw rod 53 through the chute 57. The side wall of the screw rod 53 is threadedly connected to the knob 54, and the outside of the adjustment frame 56 abuts against the knob 54;

[0046] The adjustment frame 56 is sleeved on the screw rod 53 at the bottom of the installation frame 52 through the chute 57 on the side wall. When the knob 54 is rotated, since the knob 54 is threadedly connected to the screw rod 53, when the knob 54 is loosened, the adjustment frame 56

[0047] The height between the adjusting bracket 56 and the mounting bracket 52 can be changed by moving the slide 57 on the lead screw 53, thereby enabling precise adjustment of the positions of the professional camera and light source assembly 8 on both sides of the lead screw 6 according to the actual position of the lead screw 6, so as to improve measurement accuracy.

[0048] The mounting bracket 52 has a limit plate 55 integrally formed on both sides of its edge. The two sides of the adjustment bracket 56 are slidably connected to the inside of the limit plate 55. The limit plate 55 restricts the sliding direction of the adjustment bracket 56 and prevents the adjustment bracket 56 from rotating or deviating.

[0049] like Figure 2 As shown, the bottom of the adjustment frame 56 is fixedly installed with the industrial camera 7 and the light source assembly 8 respectively. The optical lens focuses the image of the screw 6 onto the image sensor of the camera. The image sensor converts the light signal into an electrical signal, and then, after signal processing and digital conversion, forms a digital image, thereby obtaining the size information of the screw 6.

[0050] like Figure 2 As shown, the light source assembly 8 includes a mounting bracket 81 and a fill light 83. The mounting bracket 81 is fixedly installed on the bottom of the adjustment bracket 56. The two ends of the mounting bracket 81 are hinged to the two sides of the fill light 83 by bolts 82. When the fill light 83 is powered on, it emits light and illuminates the surface of the screw 6, providing sufficient illumination for the industrial camera 7 to photograph the screw 6. The hinged connection between the mounting bracket 81 and the fill light 83 can also adjust the pitch angle of the fill light 83, that is, the angle of the light source, so as to better provide sufficient light source for the industrial camera 7.

[0051] Furthermore, such as Figure 2 As shown, a light shield 84 is fixedly installed around the light source of the supplementary light 83. The light shield 84 is shaped like a platform, and a reflector 85 is installed on the inner surface of the light shield 84. The light shield 84 can limit the divergence direction of the light, so that the light can be more concentrated on the surface of the screw 6. At the same time, the reflector 85 on the inner side of the light shield 84 can reflect the light, improve the utilization rate of the light, and make the illumination on the surface of the screw 6 more uniform.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
