Description

Technical Field

[0001] This utility model relates to the technical field of wax injection gun testing, and in particular to a device for detecting blockages in the injection orifice of a wax injection gun. Background Technology

[0002] During the operation of a wax injection gun, heated molten wax is extruded from the injection orifice through a heated chamber. However, the injection orifice may become clogged, which typically leads to problems such as wax backflow and abnormal system pressure fluctuations. Current common clogging detection methods have certain limitations: methods using pressure sensors to detect pressure changes have response delays, making it difficult to provide timely warnings and accurately locate the clogging point; vision-based detection methods are easily affected by the complex lighting environment of the production site, affecting the accuracy of the judgment; and direct monitoring using contact temperature sensors is not only difficult to install and arrange, but may also interfere with the flow of the wax. In addition, relying solely on manual inspection is inefficient and cannot meet the needs for real-time monitoring and rapid response to sudden clogging. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for detecting blockages in the injection orifice of a wax injection gun.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A blockage detection device for the injection hole of a wax gun includes a base plate, slide rods, a sleeve, bolts, a groove, a frame, a rod, a spring, a clamp, an infrared temperature sensor, a first rubber pad, a scale, a second rubber pad, and a mounting hole. The base plate is fixedly connected to two slide rods, which movably pass through the same sleeve. Bolts are threaded through one end and the other end of the sleeve. The sleeve has a U-shaped groove, and the infrared temperature sensor is placed in the groove.

[0006] Preferably, the sleeve is fixedly connected to a frame, the frame has a rod that movably passes through it, a spring is sleeved on the outer surface of the rod, one end of the spring is fixedly connected to the frame, the other end of the spring is fixedly connected to the rod, a clamp is fixedly connected to the rod, the clamp is in contact with the infrared temperature sensor, and the contact point between the clamp and the infrared temperature sensor is arc-shaped.

[0007] Preferably, a second rubber pad is fixedly connected to both the clamp and the groove at the contact point with the infrared temperature sensor.

[0008] Preferably, both slide rods are fixedly connected with a first rubber pad, and the two first rubber pads are in contact with one end of the corresponding bolt.

[0009] Preferably, one end and the other end of the base plate are fixedly connected with multiple mounting holes.

[0010] Preferably, one of the slide bars has a scale.

[0011] Preferably, both bolts and the rod are fixedly connected to a handle.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination of sliding rods, sleeves, bolts, grooves, infrared temperature sensors, and scales, the sleeve moves up and down on two sliding rods. By rotating the two bolts on the sleeve, one end of the bolt contacts the corresponding sliding rod to fix the position of the sleeve. Simultaneously, the sliding rod scale positions the sleeve at a suitable height, allowing the infrared temperature sensor in the sleeve's groove to detect blockages in the wax injection gun at different heights. Compared to pressure sensors that detect pressure changes, this method offers a faster response, enabling real-time early warning and precise location of blockage points via the sliding rod scale. Compared to visual inspection methods, which are easily affected by complex ambient light, infrared temperature sensors are less affected by light, ensuring accurate judgment. Unlike contact temperature sensors, non-contact infrared detection does not require direct contact with the wax, facilitating installation and layout without interfering with the wax flow. Furthermore, this method replaces manual inspection, significantly improving detection efficiency and meeting the needs for real-time monitoring and rapid response to sudden blockages.

[0014] 2. Through the cooperation between the sleeve, frame, rod, spring, clamp and groove, the spring provides force to the rod to move the clamp downward to hold and fix the infrared temperature sensor in the groove. When disassembling, only the rod needs to be moved upward to release the clamp, saving time and effort and greatly improving maintenance efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A device for detecting blockages in the injection nozzle of a wax gun includes a base plate 1, slide rods 2, a sleeve 3, bolts 4, grooves 5, a frame 6, a rod 7, a spring 8, a clamp 9, an infrared temperature sensor 10, a first rubber pad 11, a scale 12, a second rubber pad 13, and mounting holes 14. Two slide rods 2 are fixedly connected to the base plate 1, and the two slide rods 2 movably pass through the same sleeve 3. The slide rods 2 and the sleeve 3 together form the basic frame for height adjustment of the device. The internal diameter of the sleeve 3 is the same as that of the slide rods 2. The outer diameters of the sleeve 3 and the slide rod 2 are matched to form a clearance fit, which not only ensures that the sleeve 3 can be freely raised and lowered along the axis of the slide rod 2 to adjust its height, but also prevents the sleeve 3 from shifting laterally through the constraint of the slide rod 2, ensuring the accuracy of the subsequent detection position. One end of the sleeve 3 and the other end are threaded with bolts 4. When the bolts 4 are rotated, the ends of the bolts 4 can move radially and contact the surface of the slide rod 2. The sleeve 3 is fixed at a specific height position of the slide rod 2 by friction. The sleeve 3 has a groove 5. The groove 5 is U-shaped and its opening size is adapted to the shape of the infrared temperature sensor 10. This facilitates the quick placement and removal of the sensor and also forms a preliminary limit on the sensor through the inner wall of the groove 5, providing a basic positioning for the subsequent fixation of the fixture 9. The infrared temperature sensor 10 is placed in the groove 5. Utilizing the function of the infrared temperature sensor 10 itself, it can perform non-contact detection and monitor the temperature change in the area of ​​the wax injection gun nozzle in real time. Its detection end is placed corresponding to the wax injection gun. By receiving the infrared radiation signal of the target area, it converts it into temperature data, providing core data support for blockage detection.

[0023] In this embodiment, the sleeve 3 is fixedly connected to the frame 6, and the frame 6 has a rod 7 that can move freely along the through hole of the frame 6 to realize the lifting and lowering movement of the clamp 9. A spring 8 is sleeved on the outer surface of the rod 7. One end of the spring 8 is fixedly connected to the frame 6, and the other end of the spring 8 is fixedly connected to the rod 7. When the rod 7 is subjected to force and moves upward, the spring 8 is stretched to generate elastic potential energy. After being released, the rod 7 can be reset by contraction force, providing a continuous clamping force for the clamp 9. The clamp 9 is fixedly connected to the rod 7 and contacts the infrared temperature sensor 10. The contact point between the clamp 9 and the infrared temperature sensor 10 is arc-shaped. The arc structure can increase the contact area with the sensor, so that the clamping force is evenly distributed on the sensor surface, avoiding excessive local force that could damage the sensor, and improving the stability of clamping. A second rubber pad 13 is fixedly connected to both the clamp 9 and the groove 5 at the contact point with the infrared temperature sensor 10. On the one hand, it can buffer the clamping force through its own elasticity to prevent the sensor shell from being scratched or crushed; on the other hand, it can increase the friction of the contact surface. To further prevent the sensor from loosening or shifting during the detection process, friction is applied to both slide rods 2. Each slide rod 2 is fixedly connected to a first rubber pad 11, which contacts one end of the corresponding bolt 4. When the bolt 4 is tightened against the slide rod 2, the first rubber pad 11 increases the friction between the bolt 4 and the slide rod 2, improving the stability of the sleeve 3. This also prevents the bolt 4 from making hard contact and causing indentations or damage to the surface of the slide rod 2. The base plate 1 has multiple mounting holes 14 fixedly connected to one end and the other end. The base plate 1 can be fixed to the workbench, frame, or other basic structure near the wax injection gun using external bolts or expansion screws. This ensures that the entire detection device will not shift due to vibration during operation, providing a stable foundation for detection accuracy. One slide rod 2 has a scale 12. By observing the corresponding position of the edge of the sleeve 3 and the scale 12, the operator can intuitively read the height value of the sleeve 3, enabling the positioning of the wax injection gun nozzle at different heights. This ensures that the sensor is always aligned with the detection target area. Both bolts 4 and the rod 7 are fixedly connected to handles.

[0024] The working principle of this embodiment is as follows: During use, in the wax gun blockage detection process, the sleeve 3 first moves up and down on the two slide rods 2. The two bolts 4 of the sleeve 3 are rotated so that one end of the bolt 4 contacts the corresponding slide rod 2 to fix the position of the sleeve 3. Simultaneously, the sleeve 3 is positioned at a suitable height using the scale 12 on the slide rod 2, ensuring that the infrared temperature sensor 10 in the groove 5 of the sleeve 3 is aligned with the wax gun detection points at different heights. Then, the spring 8 applies a force to the rod 7, causing the clamp 9 to move downwards, thus clamping and fixing the infrared temperature sensor 10 in the groove 5, ensuring the transmission of infrared temperature during the detection process. The sensor is stable and does not loosen. When the wax injection gun is working, the infrared temperature sensor 10 can detect blockages. Compared with the pressure sensor, it responds more quickly, can provide real-time warnings, and can accurately locate the blockage point through the scale 12 of the slider 2. Compared with visual detection, it is less affected by light interference and makes accurate judgments. Moreover, the non-contact design avoids interfering with the flow of wax liquid. It replaces manual inspection and greatly improves efficiency, meeting the needs of real-time monitoring and rapid response to sudden blockages. When maintenance is required, simply move the rod 7 upward to release the clamp 9, and the infrared temperature sensor 10 can be easily removed, saving time and effort and effectively improving maintenance efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
