Abstract
Description
Technical Field
[0001] This utility model relates to the field of colloid tube testing technology, and in particular to a colloid tube extrusion force testing device. Background Technology
[0002] In the test of extrusion force of colloid tubes, it refers to the quantitative analysis of the force exerted by the colloid when it is extruded from the tube using specialized equipment.
[0003] When a colloid is extruded from a tube, it needs to overcome resistance such as tube wall friction and the colloid's own viscosity. The force generated in this process is called "extrusion force." After the colloid tube is manufactured, samples need to be taken to evaluate the colloid's flowability, viscosity, elasticity, and other properties, as well as the rationality of the tube design.
[0004] Existing measurement methods often involve operators manually pushing the equipment to test the extrusion force of the colloid tube. However, manual operation has many limitations, such as differences in the strength, speed, and uniformity of force application among different operators, which can lead to inaccurate test results.
[0005] Therefore, we propose a novel colloid tube extrusion force testing device. Utility Model Content

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0029] Example 1, such as Figure 1 - Figure 5 As shown, this utility model provides a colloid tube extrusion force testing device, including a test platform 1. An extrusion force testing component 2 is mounted on the top of the test platform 1. The extrusion force testing component 2 includes a support frame 201. A servo motor 202 is connected to one side surface of the support frame 201. A one-way screw 203 is connected to the output end of the servo motor 202. A bearing 204 is connected to one end of the one-way screw 203. A moving block 205 is connected to the surface of the one-way screw 203. An electric push rod 206 is connected to the bottom of the moving block 205. A pressure sensor 207 is connected to the output end of the electric push rod 206. A colloid tube body 208 is connected to the surface of the test platform 1. A magnetic block 209 is embedded in the inner wall of a groove on one side of the test platform 1. A collection bucket 210 is provided in the groove of the test platform 1. Magnets 211 are connected to both sides of the collection bucket 210. The front of the test platform 1... A PLC controller 212 is connected to the end surface. A roller assembly 3 is connected to the bottom of the pressure sensor 207. The test platform 1 is located directly below the roller assembly 3 and is connected to the colloid tube body 208. The PLC controller 212 is electrically connected to an external power supply through a control switch. The PLC controller 212 is electrically connected to the servo motor 202, the electric push rod 206, and the pressure sensor 207. The output end of the servo motor 202 is fixedly connected to the one-way screw 203. The one-way screw 203 is threadedly connected to the moving block 205. The position and size of the magnet 211 match the position and size of the magnetic block 209. The magnetic block 209 and the magnet 211 are magnetically connected. The position and size of the collection bucket 210 match the position and size of the groove in the test platform 1. The collection bucket 210 and the groove are engaged.
[0030] The overall effect of Embodiment 1 is that, when testing the colloid tube body 208, the colloid tube body 208 to be tested can be clamped and fixed first using a clamp, and then the front end of the colloid tube body 208 can be cut open. Then, the pressure of the roller body 303 pressing downwards is set according to the PLC controller 212. At this time, the PLC controller 212 can be turned on for automatic testing. The PLC controller 212 will first activate the electric push rod 206, enabling the electric push rod 206 to drive the servo motor 202 to rotate in the reverse direction. This allows the servo motor 202 to drive the pressure sensor 207 and the roller body 303 to move downwards through its output end. When the roller body 303 presses against the colloid tube body 208, the pressure sensor 207 will sense it in real time. When the pressure reaches the set value, the electric push rod 206 will activate the PLC controller 212. The machine will automatically stop under the action of the PLC controller 212. Then, the PLC controller 212 will activate the reverse rotation function of the servo motor 202, so that the output end can reverse the one-way screw 203. When the one-way screw 203 rotates in reverse, it will rotate in the opposite direction with the moving block 205. In turn, the roller body 303 will be moved by the reverse rotation of the one-way screw 203, so as to realize the extrusion force test. The PLC controller 212 controls the pressure to ensure that the pressure of each group of colloid tube bodies 208 is the same during the test. It also evaluates the flowability, viscosity, elasticity and other properties of the colloid, as well as the rationality of the design of the colloid tube, such as the tube diameter and material. This avoids the problem of inaccurate test data caused by the operator manually pushing the equipment to perform the extrusion force test on the colloid tube. At the same time, the collection bucket 210 can collect the extruded colloid and can be easily fixed by magnetic connection.
[0031] Example 2, as Figure 5 and Figure 6 As shown, the roller assembly 3 includes a connecting block 301. Slots 302 are provided on both sides of the connecting block 301. The bottom of the connecting block 301 is attached to the roller body 303. Fixing blocks 304 are connected to the top of both sides of the roller body 303. Two sets of springs 305 are provided inside the fixing blocks 304. Push rod bodies 306 are inserted into the two sets of springs 305. Handles 308 are connected to the front ends of the two sets of push rod bodies 306. Insert blocks 307 are connected to the rear ends of the two sets of push rod bodies 306. The surface of the insert block 307 is provided with a bevel. The insert block 307 and the slot 302 form an insertion connection. The insert block 307 and the spring 305 form an elastic structure. The surface of the insert block 307 is provided with a bevel.
[0032] The effect achieved by the entire embodiment 2 is that when it is necessary to test the colloid tube body 208 of different diameters, the handles 308 can be pulled to both sides at the same time, so that the insert 307 can be pulled out from the slot 302. Then, the roller body 303 can be pulled down to complete the disassembly of the roller body 303. Then, the roller body 303 of the appropriate size is pushed towards the position of the connecting block 301, so that the oblique position of the insert 307 is squeezed and automatically squeezed towards the spring 305. When the position of the insert 307 is in contact with the position of the slot 302, the spring 305 will push the insert 307 into the slot 302 for quick fixation. In this way, the roller body 303 can be quickly disassembled and assembled, improving the flexibility of the device when testing the colloid tube body 208.
[0033] Working principle: When testing the colloid tube body 208, it can first be clamped and fixed by a fixture. Then, the pressure of the roller body 303 pressing downward is set according to the PLC controller 212. The roller body 303 is moved by the thread rotation of the one-way screw 203 to realize the extrusion force test. The PLC controller 212 controls the pressure to ensure that the pressure of each group of colloid tube bodies 208 is the same during testing. It evaluates the flowability, viscosity, elasticity and other properties of the colloid, as well as the rationality of the tube design, such as the tube diameter and material. This avoids the problem of inaccurate test data caused by the operator manually pushing the equipment to perform the extrusion force test on the colloid tube. By testing colloid tube bodies 208 with different diameters, different roller bodies 303 can be replaced. Each group of roller bodies 303 is connected to the top of a fixing block 304. The quick installation structure of spring 305 and insertion block 307 can realize the quick installation of the roller body 303, which improves the flexibility of the device when testing colloid tube bodies 208.
[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
