Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly adhesive production technology, specifically a temperature measuring device for environmentally friendly adhesive samples. Background Technology

[0002] Environmentally friendly adhesives are designed with environmental protection in mind, comply with national environmental standards, and are harmless to humans and the environment. Due to their excellent properties, they are widely used in construction, furniture manufacturing, automotive interiors, electronic equipment, and packaging. Temperature measurement is a crucial step in the research, development, production, and quality control of environmentally friendly adhesives. Monitoring temperature changes helps assess the performance stability and applicability of the adhesives, as temperature directly affects their performance and process reliability.

[0003] Chinese patent CN221485263U discloses a temperature testing device for adhesives, including a control terminal comprising a controller and an adjustable power supply electrically connected to the controller; a semiconductor refrigeration chip electrically connected to the output terminal of the adjustable power supply for receiving cooling / heating signals generated by the adjustable power supply; a heat-conducting unit in contact with the semiconductor refrigeration chip for heat transfer between the semiconductor refrigeration chip and the adhesive; and a feedback unit electrically connected to the controller for providing feedback on the temperature of the adhesive.

[0004] While the aforementioned temperature testing device achieves precise temperature control and ensures testing accuracy, when measuring the temperature of liquid samples of environmentally friendly adhesives, air bubbles in the sample can create a thermal barrier, slowing down the heat transfer rate. This affects the temperature response speed, measurement accuracy, and data stability. Currently, most methods for eliminating air bubbles require external equipment, and air can easily be reintroduced during manual sample handling, leading to incomplete bubble elimination. Therefore, improvements are urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide a temperature measuring device for environmentally friendly adhesive samples, so as to solve the problem mentioned in the background art that the presence of air bubbles in liquid samples affects temperature measurement and that the air bubbles are not completely eliminated.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature measuring device for environmentally friendly adhesive samples, comprising a device platform, a device frame fixed above the device platform, a second cylinder mounted on the top of the device frame, and a temperature measuring module disposed below the second cylinder. The temperature measuring module includes a temperature measuring module and temperature measuring probes. The temperature measuring module is fixed to the output end of the temperature measuring module, and the temperature measuring probes are evenly spaced at the bottom end of the temperature measuring module. A motor is mounted inside one end of the device platform, and a lead screw is mounted at the output end of the motor. The lead screw is externally sleeved... The device is equipped with a slider, the top of which extends above the device body and is fixed to a support platform. A sample box is provided at the top of the support platform. A support base is fixed to one side of the top of the device body. A first cylinder is installed on the outer wall of one side of the support base. A vacuum sealing cover is installed at the output end of the first cylinder. The vacuum sealing cover cooperates with the sample box. A suction pipe is installed on one side of the top of the vacuum sealing cover. A vacuum pump is installed inside the support base. A vacuum tube is installed at the input end of the vacuum pump. One end of the vacuum tube extends to the outside of the support base and is connected to the suction pipe.

[0007] Preferably, a pressure relief pipe is installed on the other side of the top of the vacuum sealing cover, and a solenoid valve is installed at the connection between the pressure relief pipe and the vacuum sealing cover.

[0008] Preferably, a retaining ring is fixed at the edge of the top of the support platform, and the retaining ring is in contact with the sample box.

[0009] Preferably, the slider is threadedly engaged with the lead screw, and guide rods are fixed inside the device platform on both sides of the lead screw, with the guide rods passing through the slider.

[0010] Preferably, a cleaning mechanism is provided on the inner wall of the bottom of the device frame. The cleaning mechanism includes a support plate, an electric telescopic rod, a clamping block, and a non-woven fabric to facilitate cleaning of the probe.

[0011] Preferably, the support plate is fixed on the inner wall of the device frame on both sides of the temperature probe, and the electric telescopic rod is installed on the outer wall of the support plate, with the output end of the electric telescopic rod penetrating through the support plate.

[0012] Preferably, the clamping block is disposed on the side of the support plate away from the electric telescopic rod, the clamping block is fixedly connected to the output end of the electric telescopic rod, and the non-woven fabric is disposed on the surface of the clamping block.

[0013] Preferably, a loop fastener is sewn onto the surface of the nonwoven fabric near the clamping block, and the loop fastener is tightly adhered to the loop fastener barb on the surface of the clamping block.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The first cylinder drives the vacuum sealing cap downward to tightly engage with the sample box, sealing the sample box. The vacuum pump operates to gradually increase the vacuum level of the sample box through the vacuum tube. By reducing the ambient air pressure, the solubility of dissolved gases in the adhesive decreases. Due to the pressure difference between the inside and outside, the bubbles expand and merge, eventually escaping from the liquid. This defoaming method does not change the composition of the adhesive or its environmental performance. After the liquid surface is stable and free of bubbles, the solenoid valve is opened and the pressure relief pipe is used to slowly release the gas. Then, the first cylinder is controlled to drive the vacuum sealing cap upward to separate it from the sample box. The motor is then started to drive the lead screw to rotate, causing the slider to move the carrier platform horizontally. The carrier platform moves the sample box smoothly to the bottom of the temperature measuring module. This device has a built-in defoaming function, and the defoaming process and temperature measuring process are highly integrated, replacing manual handling and preventing the regeneration of bubbles, thus achieving complete elimination of bubbles. The temperature measuring module is moved upward by the second cylinder, causing the temperature probe to be removed from the sample. Since there is a cleaning mechanism at the bottom of the device frame, the electric telescopic rod is activated to drive the clamping block to move horizontally. The clamping block moves the non-woven fabric to clamp the temperature probe. During the upward movement of the temperature probe, the non-woven fabric wipes the sample off the surface of the temperature probe, which facilitates quick cleaning of the temperature probe and prevents the sample from hardening and being difficult to remove. The non-woven fabric is fixed to the surface of the clamping block by Velcro round hair pieces and Velcro barbs, making the non-woven fabric removable and easy to clean or replace.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 An embodiment of this utility model provides a temperature measuring device for an environmentally friendly adhesive sample, including a device platform 1, a device frame 7 fixed above the device platform 1, a second cylinder 8 installed on the top of the device frame 7, and a temperature measuring module 9 arranged below the second cylinder 8. The temperature measuring module 9 includes a temperature measuring module 16 and a temperature measuring probe 17. The temperature measuring module 16 is fixed at the output end of the temperature measuring module 9, and the temperature measuring probe 17 is installed at equal intervals at the bottom end of the temperature measuring module 16. Specifically, see the attached document. Figure 3 The second cylinder 8 drives the temperature measuring module 9 to move down, so that the temperature measuring probe 17 at the bottom of the temperature measuring module 16 is inserted into the sample inside the sample box 15. The use of three sets of temperature measuring probes 17 can measure the temperature at the center and the edge, making the temperature measurement data more valuable. A motor 11 is installed at one end inside the device platform 1, and a lead screw 12 is installed at the output end of the motor 11. A slider 13 is fitted on the outside of the lead screw 12, and the top of the slider 13 extends to the top of the device platform 1 and is fixed to a support platform 14. A sample box 15 is set at the top of the support platform 14. A support base 2 is fixed on one side of the top of the device platform 1, and a first cylinder 5 is installed on the outer wall of one side of the support base 2. A vacuum sealing cover 6 is installed at the output end of the first cylinder 5. The vacuum sealing cover 6 cooperates with the sample box 15. A suction pipe 18 is installed on one side of the top of the vacuum sealing cover 6. A vacuum pump 3 is installed inside the support base 2, and a vacuum tube 4 is installed at the input end of the vacuum pump 3. One end of the vacuum tube 4 extends to the outside of the support base 2 and is connected to the suction pipe 18. Specifically, referring to Annexes 1, 2, and 4, the liquid sample of the environmentally friendly adhesive is poured into the sample box 15. The sample box 15 is placed on the support platform 14, and the retaining ring 1401 limits and fixes it. At this time, the sample box 15 is located directly below the vacuum sealing cover 6. The first cylinder 5 drives the vacuum sealing cover 6 to move down so that it is tightly locked with the sample box 15, sealing the sample box 15. Then, the vacuum pump 3 operates to gradually increase the vacuum degree of the sample box 15 through the vacuum tube 4. By reducing the ambient air pressure, the solubility of the dissolved gas in the adhesive decreases. Due to the pressure difference between the inside and outside, the bubbles expand and merge, and finally escape from the liquid. This defoaming method does not change the composition and environmental performance of the adhesive throughout the process. After the liquid surface is stable and there are no bubbles, the solenoid valve 20 is opened and the gas is slowly released through the pressure relief pipe 19. Then, the first cylinder 5 is controlled to drive the vacuum sealing cover 6 to move up so that it separates from the sample box 15. Then start the motor 11 to drive the lead screw 12 to rotate, so that the slider 13 drives the support platform 14 to move horizontally. The support platform 14 drives the sample box 15 to move smoothly to the bottom of the temperature measuring module 9. The device has a built-in defoaming function, and the defoaming process and the temperature measuring process have a high degree of connection. It replaces manual handling and prevents bubbles from being generated again, thus achieving complete elimination of bubbles. A pressure relief pipe 19 is installed on the other side of the top of the vacuum sealing cover 6, and a solenoid valve 20 is installed at the connection between the pressure relief pipe 19 and the vacuum sealing cover 6. A retaining ring 1401 is fixed at the edge of the top of the support platform 14, and the retaining ring 1401 is in contact with the sample box 15. The slider 13 is threadedly engaged with the lead screw 12. Guide rods 101 are fixed inside the device platform 1 on both sides of the lead screw 12, and the guide rods 101 pass through the slider 13. A cleaning mechanism 10 is provided on the inner wall at the bottom of the device frame 7. The cleaning mechanism 10 includes a support plate 21, an electric telescopic rod 22, a clamping block 23, and a non-woven fabric 24. The support plate 21 is fixed on the inner wall of the device frame 7 on both sides of the temperature probe 17, and the electric telescopic rod 22 is installed on the outer wall of the support plate 21. The output end of the electric telescopic rod 22 passes through the support plate 21. The clamping block 23 is located on the side of the support plate 21 away from the electric telescopic rod 22. The clamping block 23 is fixedly connected to the output end of the electric telescopic rod 22. The non-woven fabric 24 is located on the surface of the clamping block 23. A Velcro round piece 2401 is sewn onto the surface of the non-woven fabric 24 near the clamping block 23, and the Velcro round piece 2401 is tightly attached to the Velcro barbed piece 2301 on the surface of the clamping block 23. Furthermore, the second cylinder 8 drives the temperature measuring module 9 to move upward, causing the temperature measuring probe 17 to be removed from the sample. Since the bottom of the device frame 7 is equipped with a cleaning mechanism 10, the electric telescopic rod 22 is activated to drive the clamping block 23 to move horizontally. The clamping block 23 drives the non-woven fabric 24 to clamp the temperature measuring probe 17. During the upward movement of the temperature measuring probe 17, the non-woven fabric 24 wipes away the sample from the surface of the temperature measuring probe 17, thereby facilitating quick cleaning of the temperature measuring probe 17 and preventing the sample from hardening and becoming difficult to remove. The non-woven fabric 24 is fixed to the surface of the clamping block 23 by the Velcro round loop piece 2401 and the Velcro barbed piece 2301, making the non-woven fabric 24 detachable, thereby facilitating cleaning or replacement.

[0020] In this embodiment, the following steps are taken: First, the liquid sample of the environmentally friendly adhesive is poured into the sample box 15. The sample box 15 is then placed on the support platform 14, and the retaining ring 1401 limits and fixes it. At this time, the sample box 15 is directly below the vacuum sealing cover 6. The first cylinder 5 drives the vacuum sealing cover 6 to move down so that it tightly engages with the sample box 15, sealing the sample box 15. Next, the vacuum pump 3 operates to gradually increase the vacuum level of the sample box 15 through the vacuum tube 4. By reducing the ambient air pressure, the solubility of the dissolved gases in the adhesive decreases. Due to the pressure difference between the inside and outside, the bubbles expand and merge, eventually escaping from the liquid. This defoaming method does not change the adhesive composition or environmental performance throughout the process. After the liquid surface is stable and free of bubbles, the solenoid valve 20 is opened and the pressure relief pipe 19 is used to slowly release the air. Then, the first cylinder 5 is controlled to drive the vacuum sealing cover 6 to move upward, separating it from the sample box 15. The motor 11 is then started to drive the lead screw 12 to rotate, causing the slider 13 to move the support platform 14 horizontally. The support platform 14 then moves the sample box 15 smoothly to below the temperature measuring module 9. This device has a built-in defoaming function, and the defoaming... The high degree of integration between the process and the temperature measurement process replaces manual handling, preventing the regeneration of bubbles and thus achieving complete bubble elimination. Next, the second cylinder 8 drives the temperature measurement module 9 downwards, allowing the temperature probe 17 at the bottom of the temperature measurement module 16 to be inserted into the sample inside the sample box 15. Using three sets of temperature probes 17 allows for temperature measurement at the center and edges, making the temperature data more valuable. Finally, after the temperature measurement is complete, the second cylinder 8 drives the temperature measurement module 9 upwards, removing the temperature probe 17 from the sample. Due to the device frame... 7. A cleaning mechanism 10 is provided at the bottom. When the electric telescopic rod 22 is activated, it drives the clamping block 23 to move horizontally. The clamping block 23 drives the non-woven fabric 24 to clamp the temperature probe 17. During the upward movement of the temperature probe 17, the non-woven fabric 24 wipes away the sample on the surface of the temperature probe 17, which facilitates quick cleaning of the temperature probe 17 and prevents the sample from hardening and being difficult to remove. The non-woven fabric 24 is fixed to the surface of the clamping block 23 by the Velcro round hair piece 2401 and the Velcro barbed hair piece 2301, which makes the non-woven fabric 24 detachable, thus facilitating cleaning or replacement.
