Description

Technical Field

[0001] This utility model belongs to the field of polyester resin technology, and in particular relates to a testing device for the softening point of polyester resin. Background Technology

[0002] The polyester resin softening point tester is a specialized device designed for the accurate determination of the softening temperature of polyester resin. It simulates the resin softening process under heat and determines the softening point based on its specific flow or deformation state, providing key temperature parameters for subsequent resin processing. It also has the advantages of high testing accuracy, standardized operation, and compatibility with different resin types.

[0003] During resin testing, if the resin flow is sometimes fast and sometimes slow, the unstable fluid will cause great differences in the flow rate and flow state of each group, which will affect the final test results and reduce the accuracy of the test. To address the above problems, the following solutions are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for the softening point of polyester resin. By setting up a testing mechanism, the problem of inconsistent resin flow speed and fluid instability leading to significant differences in flow rate and flow state between groups is solved, which affects the final test results and reduces the accuracy of the test.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a testing device for the softening point of polyester resin, including a fixed frame, the fixed frame further including a testing mechanism, a main body fixedly connected to the inner wall of the fixed frame, a feed pipe fixedly connected to the top of the main body, a booster pump fixedly connected to the top of the main body, and an air inlet pipe fixedly connected to the air inlet of the booster pump.

[0007] Furthermore, the outlet of the booster pump is fixedly connected to an outlet pipe, and the end of the outlet pipe away from the booster pump extends into the main body and is fixedly connected to the main body.

[0008] Furthermore, a storage slot is provided inside the main body, and a support plate is fixedly connected to the outer wall of the main body.

[0009] Furthermore, a motor is fixedly connected to the bottom of the support plate, and a baffle is fixedly connected to the output shaft of the motor, with the top of the baffle in contact with the main body.

[0010] Furthermore, the outer wall of the fixed frame is fixedly connected with several support legs, and the bottom of the fixed frame is fixedly connected with an annular plate.

[0011] Furthermore, a rotating plate is threadedly connected to the inner wall of the annular plate, and a handle is fixedly connected to the bottom of the rotating plate.

[0012] Furthermore, a support rod is fixedly connected to the side of the rotating plate away from the handle, and a collection box is fixedly connected to the end of the support rod away from the rotating plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. When using this device to test the softening point of polyester resin, first pour the polyester resin to be tested into the storage tank through the feed pipe, then start the booster pump. The booster pump draws in gas through the air inlet pipe, pressurizes the gas, and then delivers it to the storage tank through the air outlet pipe, applying downward pressure to the polyester resin in the storage tank. The booster pump applies downward pressure to the resin by stabilizing the air pressure, which can push the resin to flow at a uniform speed. When the air pressure in the storage tank reaches the specified threshold, start the motor. The motor drives the baffle to rotate. At this time, the baffle no longer obstructs the main body. The operator can test the softening point of the resin by observing the flow of resin from the bottom of the main body. Before the test, the baffle effectively obstructs the main body, preventing the resin from flowing out prematurely before it is ready. During the test, the baffle rotates rapidly, which can instantly open the flow channel, allowing the operator to observe the resin flow state, thereby ensuring the accuracy of the test data.

[0015] 2. After the test is completed, the booster pump increases the air pressure applied to the storage tank. The booster pump actively increases the air pressure, using higher pressure to push all the resin adhering to the inner wall of the storage tank towards the outflow channel, allowing all the resin in the storage tank to flow out. This prevents the residual resin from curing and forming hard scale, and also ensures that new resin will not mix with the residual material during the next test, guaranteeing the purity of the test sample from the source and avoiding data deviation. The resin after the test will flow into the collection box. The operator can rotate the rotating plate by turning the handle. After the rotating plate rotates, it separates from the annular plate, making it easy for the operator to remove the collection box for cleaning, so as to conduct the next resin test, thus improving the convenience of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a testing device for the softening point of polyester resin, including a fixed frame 101. The fixed frame 101 also includes a testing mechanism 1. A main body 102 is fixedly connected to the inner wall of the fixed frame 101. A feed pipe 103 is fixedly connected to the top of the main body 102. A booster pump 104 is fixedly connected to the top of the main body 102. An air inlet pipe 105 is fixedly connected to the air inlet of the booster pump 104. An air outlet pipe 106 is fixedly connected to the air outlet of the booster pump 104. One end of the air outlet pipe 106 away from the booster pump 104 extends into the main body 102 and is fixedly connected to the main body 102.

[0027] Start the booster pump 104. The booster pump 104 draws in gas through the air inlet pipe 105, pressurizes the gas, and then delivers it to the storage tank 107 through the air outlet pipe 106. It applies downward pressure to the polyester resin in the storage tank 107. The booster pump 104 applies downward pressure to the resin by stabilizing the air pressure, which can push the resin to flow at a uniform speed.

[0028] A storage slot 107 is provided inside the main body 102. A support plate 108 is fixedly connected to the outer wall of the main body 102. A motor 109 is fixedly connected to the bottom of the support plate 108. A baffle 110 is fixedly connected to the output shaft of the motor 109. The top of the baffle 110 is in contact with the main body 102.

[0029] When the air pressure in the storage tank 107 reaches the specified threshold, the motor 109 is started. The motor 109 drives the baffle 110 to rotate. At this time, the baffle 110 no longer blocks the main body 102. The staff tests the softening point of the resin by observing the state of the resin flowing out from the bottom of the main body 102.

[0030] The outer wall of the fixed frame 101 is fixedly connected with several support legs 111. The bottom of the fixed frame 101 is fixedly connected with an annular plate 112. The inner wall of the annular plate 112 is threadedly connected with a rotating plate 113. The bottom of the rotating plate 113 is fixedly connected with a handle 114. The side of the rotating plate 113 away from the handle 114 is fixedly connected with a support rod 115. The end of the support rod 115 away from the rotating plate 113 is fixedly connected with a collection box 116.

[0031] The booster pump 104 increases the air pressure applied to the storage tank 107. The booster pump 104 actively increases the air pressure and uses higher pressure to push all the resin adhering to the inner wall of the storage tank 107 toward the outflow channel, so that all the resin in the storage tank 107 flows out. This can prevent the residual resin from curing and forming hard scale.

[0032] The working principle of the polyester resin softening point testing device provided by this utility model is as follows: When it is necessary to use this device to test the softening point of polyester resin, firstly, the polyester resin to be tested is poured into the storage tank 107 through the feed pipe 103, and then the booster pump 104 is started. The booster pump 104 draws in gas through the air inlet pipe 105, pressurizes the gas after it is drawn in, and then delivers it to the storage tank 107 through the air outlet pipe 106, applying downward pressure to the polyester resin in the storage tank 107. The booster pump 104 applies downward pressure to the resin by stabilizing the air pressure, which can push the resin to flow at a uniform speed. When the air pressure in the storage tank 107 reaches the specified threshold, the motor 109 is started. The motor 109 drives the baffle 110 to rotate. At this time, the baffle 110 no longer blocks the main body 102. The staff tests the softening point of the resin by observing the state of the resin flowing out from the bottom of the main body 102.

[0033] After the test is completed, the booster pump 104 increases the air pressure applied to the storage tank 107. The booster pump 104 actively increases the air pressure and uses higher pressure to push all the resin adhering to the inner wall of the storage tank 107 to the outflow channel, so that all the resin in the storage tank 107 flows out. This can prevent the residual resin from curing and forming hard scale. At the same time, it ensures that the new resin will not mix with the residual material in the next test, thus ensuring the purity of the test sample from the source and avoiding data deviation.

[0034] A specific application of this embodiment is as follows: When it is necessary to use this device to test the softening point of polyester resin, firstly, the polyester resin to be tested is poured into the storage tank 107 through the feed pipe 103, and then the booster pump 104 is started. The booster pump 104 draws in gas through the air inlet pipe 105, pressurizes the gas, and then delivers it to the storage tank 107 through the air outlet pipe 106, applying downward pressure to the polyester resin in the storage tank 107. The booster pump 104 applies downward pressure to the resin by stabilizing the air pressure, which can push the resin evenly. Rapid flow: When the air pressure in the storage tank 107 reaches the specified threshold, the motor 109 is started. The motor 109 drives the baffle 110 to rotate. At this time, the baffle 110 no longer obstructs the main body 102. The staff can test the softening point of the resin by observing the flow state of the resin from the bottom of the main body 102. Before the test, the baffle effectively obstructs the main body to prevent the resin from flowing out prematurely before it is ready. During the test, the baffle rotates rapidly, which can instantly open the flow channel, allowing the staff to observe the resin flow state, thereby ensuring the accuracy of the test data.

[0035] After the test is completed, the booster pump 104 increases the air pressure applied to the storage tank 107. The booster pump 104 actively increases the air pressure, using higher pressure to push all the resin adhering to the inner wall of the storage tank 107 towards the outflow channel, so that all the resin in the storage tank 107 flows out. This can prevent the residual resin from solidifying and forming hard scale, and at the same time ensure that the new resin will not mix with the residual material in the next test, thus ensuring the purity of the test sample from the source and avoiding data deviation. The resin after the test will flow into the collection box 116. The operator can rotate the rotating plate 113 by turning the handle 114. After the rotating plate 113 rotates, it separates from the annular plate 112, making it convenient for the operator to take out the collection box 116 for cleaning, so as to conduct the next resin test, which improves the convenience of the device.
