Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0027] As described in the background art, the current devices for measuring the constant load holding performance of viscous raw materials in the industry can only read the holding time to final failure, but cannot read the instantaneous displacements during the entire test process (the displacement of the viscous raw material from the steel sheet).
[0028] In order to solve this technical problem, the utility model provides a device for measuring the constant load holding performance of viscous raw materials.
[0029] Specifically, please refer to Figure 1-2 The device for measuring the constant load holding performance of viscous raw materials specifically includes:
[0030] Chassis 1, column 2, seesaw assembly 3, viscous material assembly 4, weight 5, steel wire 6, tension sensor 7, chassis 1 is provided with chassis circular hole 8, column 2 is arranged on chassis circular hole 8, the top end of column 2 is movably matched with seesaw assembly 3, one end of steel wire 6 is fixedly connected to seesaw assembly 3, the other end of steel wire 6 is connected to the first pair of hooks 9 of tension sensor 7, the other end of seesaw assembly 3 is bonded with viscous material assembly 4, the lower end of viscous material assembly 4 is movably adapted with weight 5.
[0031] The utility model provides a device for measuring the constant load holding performance of a viscous raw material. By setting a viscous material component 4 at one end of a seesaw component 3 and then hanging a weight 5, a tension sensor 7 is pulled by a steel wire 6 at the other end. The utility model utilizes the lever balance principle to record the tension of the steel wire 6 of the tension sensor 7 at all times and convert it into the size of the peeling displacement of the viscous material. The utility model has a simple design structure and can read the displacement of each instantaneous viscous raw material from the steel sheet 34, thereby accurately testing the performance of the viscous material.
[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example 1
[0035] Please refer to Figure 1-2 A device for measuring the constant load holding performance of a viscous raw material includes a chassis 1, a column 2, a seesaw assembly 3, a viscous material assembly 4, a weight 5, a steel wire 6, and a tension sensor 7. The chassis 1 is provided with a chassis circular hole 8, the column 2 is arranged on the chassis circular hole 8, the top of the column 2 is movably matched with the seesaw assembly 3, one end of the steel wire 6 is fixedly connected to the seesaw assembly 3, and the other end of the steel wire 6 is connected to the first pair of hooks 9 of the tension sensor 7, the other end of the seesaw assembly 3 is bonded with the viscous material assembly 4, and the lower end of the viscous material assembly 4 is movably adapted with a weight 5.
[0036] Through the above structural design, the first pair of hooks 9 is set on the tension sensor 7, and its function is to connect the steel wire 6 to conduct force; after installing all the components, the steel wire 6 is in a tension state, and the whole device is in a balanced state. At this time, through the human-computer interaction interface, the tension sensor 7 is started, and the tension value at this moment is set to zero. Subsequently, under the action of the weight 5, the viscous material body 41 is continuously peeled downward, and the torque on the right side of the seesaw assembly 3 becomes smaller. Since the left side of the seesaw is always in a tension state, the tension of the steel wire 6 also decreases, and the value recorded by the tension sensor 7 changes. The steel wire 6 is always in a tension state, and since the tension on the right side of the seesaw assembly 3 is not particularly large, the deformation of the steel wire 6 can be ignored during the entire test process, and it can be considered that the entire device is always in a dynamically changing equilibrium state.
[0037] When the adhesive material assembly 4 is peeled off to the point close to the second insert plate groove 33, it is blocked by the second insert plate groove 33 and is no longer peeled off. At this time, the value recorded by the tension sensor 7 remains unchanged.
[0038] The tensile force variation curve can be read through the USB interface, and the tensile force variation curve can be converted into the peeling displacement curve of the viscous material component 4 through calculation (or built-in algorithm). This is easy to calculate, and the equilibrium equation F*L=G*S can be obtained, and S=F*L / G can be obtained. Because F is set to zero in the initial equilibrium state, the change of F represents the change of S, which directly represents the peeling displacement of the viscous material.
[0039] By setting a viscous material component 4 at one end of the seesaw component 3 and then hanging a weight 5, and using a steel wire 6 to pull the tension sensor 7 at the other end, the lever balance principle is used to record the tension of the steel wire 6 of the tension sensor 7 at all times and convert it into the size of the peeling displacement of the viscous material body 41. The design has a simple structure and can read the displacement of each instantaneous viscous raw material from the steel sheet 34, thereby accurately testing the performance of the viscous material.
[0040] Specifically, the seesaw assembly 3 is hinged to the top end of the column 2 through a pin 10 .
[0041] Through the above structural design, a pin 10 hole is made on the top of the column 2 for installing the seesaw assembly 3.
[0042] Specifically, the seesaw assembly 3 includes a connecting plate 31, a first plug plate slot 32, a second plug plate slot 33 and a steel sheet 34. The connecting plate 31 and the column 2 are hinged by a pin 10. The first plug plate slot 32 is fixedly connected to one end of the connecting plate 31, and the second plug plate slot 33 is fixedly connected to the other end of the connecting plate 31. The steel sheet 34 is movably connected to the second plug plate slot 33. The first plug plate slot 32 is provided with a second pair of hooks 35 for connecting the steel wire 6.
[0043] Through the above structural design, the seesaw assembly 3 has a steel sheet 34, a first plug-in plate slot 32, a second plug-in plate slot 33, a pin hole, and a second hook. The steel sheet 34 is inserted into the second plug-in plate slot 33 for position limiting. The purpose of setting the second hook is to install the seesaw assembly 3 on the column 2 upside down, and the steel wire 6 can be wound around it. The steel sheet 34 is inserted into the plug-in plate slot to limit the distance that the sticky raw material is separated from the steel sheet 34, so as to prevent the weight 5 from falling off and damaging the bottom plate.
[0044] Specifically, the viscous material assembly 4 includes a viscous material body 41 and a hanger 42 , the weight 5 is detachably connected to the hanger 42 , the hanger 42 is fixedly connected to the viscous material assembly 4 , and the viscous material assembly 4 is bonded to the steel sheet 34 .
[0045] Through the above structural design, the viscous material is attached to the steel sheet 34, and the other end is wrapped around the sticking hanger 42, and a weight 5 of a certain mass is hung under the hanger 42. After the viscous material body 41 is attached to the steel sheet 34, the steel sheet 34 with a part of the viscous material body 41 is inserted into the second plug-in plate slot 33 of the seesaw assembly 3. In this way, the viscous material body 41 is gradually peeled off under the gravity of the weight 5, and when it reaches the edge of the plug-in plate slot, it will no longer peel off, and the weight 5 will not fall off. The tester does not need to pay attention to the displacement of the viscous raw material from the steel sheet 34 at all times, and the tester can do other work. The design of the hanger 42 is just suitable for the viscous raw material with a width of one inch, so that the viscous raw material is evenly stressed when it is pulled. The round hole of the hanger 42 is suitable for hanging the weight 5.
[0046] Specifically, the tension sensor 7 is fixed on the chassis 1 by means of screws or adhesive.
[0047] Through the above structural design, the chassis 1 plays the role of fixing the column 2 and the tension sensor 7. The column 2 is inserted into the circular hole 8 of the chassis, and the tension sensor 7 is installed and fixed on the chassis 1 by screws, adhesives, etc.
[0048] Specifically, the length of the steel wire 6 is equal to the distance between the tension sensor 7 and the first inserting plate slot 32 .
[0049] Through the above structural design, the two ends of the steel wire 6 are respectively wound on the hook of the tension sensor 7 and the hook of the seesaw assembly 3, and are always in a vertically stretched state. The deformation of the steel wire 6 can be ignored, and the force line of the weight 5 pulling down, the direction of the viscous material body 41 peeling, and the tension direction of the steel wire 6 all need to be on the same plane. Therefore, the appearance design of each material is symmetrical, and the installation is also symmetrical. Example 2
[0050] The device for measuring the constant load holding performance of viscous raw materials provided in Example 1 is further optimized, specifically, as follows Figure 1-2 As shown, a groove 11 is provided at the top end of the column 2 , and the connecting piece is hinged in the groove 11 through a pin 10 .
[0051] Through the above structural design, a pin 10 hole is provided in the groove 11 for installing the seesaw assembly 3 . Example 3
[0052] The device for measuring the constant load holding performance of viscous raw materials provided in Example 1 or 2 is further optimized, such as Figure 1-2 As shown, the thickness of the steel sheet 34 is 0.1 cm to 0.2 cm.
[0053] Through the above structural design, in this embodiment, the thickness of the steel sheet 34 is 0.1 cm, and it can also be other sizes under different circumstances.
[0054] Specifically, the force line of the weight 5 pulling down, the direction of the adhesive material peeling off, and the pulling direction of the steel wire 6 are all on the same plane.
[0055] Through the above structural design, the lever balance principle is used to record the tension of the steel wire 6 of the tension sensor 7 at all times and convert it into the size of the peeling displacement of the viscous material. Therefore, the appearance design of each material is symmetrical and the installation is also symmetrical.
[0056] Specifically, the depth of the groove 11 is 1 cm to 2 cm.
[0057] Through the above structural design, in this embodiment, the depth of the groove 11 is 1 cm.
[0058] The use process of the device for measuring the constant load holding performance of viscous raw materials provided by the utility model is as follows:
[0059] After installing all the components, the steel wire 6 is in a tension state, and the entire device is in a balanced state. At this time, through the human-computer interaction interface, the tension sensor 7 is started, and the tension value at this moment is set to zero. Subsequently, under the action of the weight 5, the viscous material body 41 is continuously peeled downward, and the torque on the right side of the seesaw assembly 3 decreases. Since the left side of the seesaw is always in a tension state, the tension of the steel wire 6 also decreases, and the value recorded by the tension sensor 7 changes. The steel wire 6 is always in a tension state, and since the tension on the right side of the seesaw assembly 3 is not particularly large, the deformation of the steel wire 6 can be ignored during the entire test process, and it can be considered that the entire device is always in a dynamically changing equilibrium state.
[0060] When the adhesive material assembly 4 is peeled off to the point close to the second insert plate groove 33, it is blocked by the second insert plate groove 33 and is no longer peeled off. At this time, the value recorded by the tension sensor 7 remains unchanged.
[0061] The tension change curve can be read through the USB interface, and the tension change curve can be converted into the viscous material peeling displacement curve through calculation (or built-in algorithm). This is easy to calculate, and the equilibrium equation F*L=G*S (wire rope tension F, constant displacement L, variable displacement S, and the gravity of the pendant and the weight G) can be obtained, and S=F*L / G can be obtained. Because F is set to zero in the initial equilibrium state, the change in F represents the change in S, which directly represents the viscous material peeling displacement.
