Description

Technical Field

[0001] This utility model relates to the field of plastic pipe extrusion testing technology, specifically to an intelligent plastic pipe extrusion testing machine with temperature warning function. Background Technology

[0002] Plastic pipe extrusion is a process of processing plastic materials into tubular products through extrusion molding. Specifically, plastic pipe extrusion involves continuously passing heated molten plastic through a die using an extruder to form a pipe of the desired shape.

[0003] The extrusion temperature of plastic pipes has a significant impact on their quality and performance. It directly affects the melt state, flow properties, and the physical and mechanical properties and appearance quality of the final product. Therefore, temperature monitoring is necessary during plastic pipe extrusion.

[0004] For example, Chinese utility model patent application number 201820273817.X discloses a novel extrusion temperature detection device. This device not only measures the extrusion temperature for extended periods, allowing operators to visually observe the temperature on the control panel, but also incorporates feedback control. It can issue an alarm based on whether the set value is exceeded and automatically adjust the extrusion machine temperature, thus improving the quality control of the extruded cable. However, this device still has certain shortcomings.

[0005] When detecting the temperature of extruded materials, it is impossible to mark the parts of the material with abnormal temperature, which makes it difficult to remove the material with abnormal temperature in the subsequent process, causing many inconveniences and potential quality problems in the production process.

[0006] Therefore, we propose an intelligent inspection machine for plastic pipe extrusion with temperature early warning function to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide an intelligent inspection machine for plastic pipe extrusion with a temperature warning function, in order to solve the problem mentioned in the background art that the current market cannot mark the parts of the material with abnormal temperature when detecting the temperature of the extruded material, which makes it inconvenient to remove the material with abnormal temperature in the subsequent work, and brings many inconveniences and quality risks to the production process.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a smart testing machine for plastic pipe extrusion with temperature early warning function, comprising a testing machine body, a first adjusting threaded rod installed on the upper part of the testing machine body, and a connecting frame installed below the first adjusting threaded rod via a first bearing seat, and a temperature probe assembly and a support base plate installed below the connecting frame;

[0009] A second adjusting threaded rod is installed on the support base plate, and a movable frame is installed above the second adjusting threaded rod via a second bearing seat;

[0010] The upper surface of the movable frame is provided with a fixed box, and a connecting pipe is installed on the left side of the fixed box. A nozzle is installed at the lower end of the connecting pipe. A forward and reverse motor is installed on the front surface of the fixed box, and a drive shaft is installed at the rear end of the forward and reverse motor through a bearing seat. A gear mechanism is installed on the drive shaft. A partition assembly is installed inside the fixed box. A sealing block is provided below the partition assembly, and a rack and pinion mechanism is installed on the right side of the sealing block.

[0011] Preferably, the first adjusting threaded rod is threadedly connected to the testing machine body, the first adjusting threaded rod is rotatably connected to the first bearing seat, and the testing machine body is provided with an inspection door.

[0012] With the above structural design, rotating the first adjusting threaded rod, which is threadedly connected to the main body of the testing machine and rotatably connected to the first bearing seat, can drive the connecting frame to move up and down, thereby adjusting the height of the temperature probe assembly so that it can accurately monitor the temperature at different positions during the plastic pipe extrusion process, adapting to the production of plastic pipes with different diameters or extrusion processes.

[0013] Preferably, the second adjusting threaded rod is threadedly connected to the support base plate, the second adjusting threaded rod is rotatably connected to the second bearing seat, and the movable frame abuts against the lower surface of the fixed box.

[0014] With the above structural design, rotating the second adjusting threaded rod causes the movable frame to move the fixed box upward, so that the fixed box is clamped between the movable frame and the inner top of the testing machine body, thereby facilitating the installation and disassembly of the fixed box.

[0015] Preferably, the height of the nozzle is greater than the height of the temperature probe assembly, and the connecting pipe is connected to the interior of the fixed box.

[0016] With the above structural design, the temperature probe assembly facilitates the detection of the surface temperature of the plastic extrusion tube.

[0017] Preferably, a spray pigment liquid is provided above the partition assembly, a feeding port is installed on the partition assembly, and the feeding port is located above the sealing block. The surface of the sealing block is designed with a rubber structure.

[0018] With the above structural design, when the sealing block coincides with the feeding port, it can seal the feeding port.

[0019] Preferably, a guide rod extends through the sealing block, the guide rod is fixed inside the fixed box, and the sealing block is slidably connected to the guide rod.

[0020] With the above structural design, the sealing block can slide left and right along the guide rod when it is subjected to force and moves left and right, thus making the sealing block more stable when moving left and right.

[0021] Preferably, the rack mechanism is located above the gear mechanism, and the gear mechanism and the rack mechanism mesh with each other.

[0022] With the above structural design, when the temperature probe assembly detects an abnormal temperature in the extrusion tube that exceeds the set temperature range, the temperature probe assembly sends a signal to the control system. The control system then starts the forward and reverse motors, which drive the drive shaft to rotate. The gear mechanism mounted on the drive shaft rotates accordingly. The rotation of the gears causes the rack mechanism to move left and right. When the sealing block moves to the right, the feed port opens, and the spray pigment liquid stored above the partition assembly flows through the connecting pipe to the nozzle and is evenly sprayed out from the nozzle, forming a clear mark on the surface of the plastic tube.

[0023] Compared with the prior art, the beneficial effects of this utility model are: the intelligent inspection machine for plastic pipe extrusion with temperature early warning function:

[0024] 1. Equipped with forward and reverse motors, the moving distance and speed of the sealing block can be precisely controlled by adjusting the speed and direction of the forward and reverse motors, thereby achieving precise control of the flow rate and spraying time of the sprayed pigment liquid, meeting the marking requirements under different production needs, thus facilitating the marking of abnormal plastic extrusion tubes, making it easier to cut them off later, and improving the processing efficiency of plastic extrusion tubes.

[0025] 2. A first adjusting threaded rod is provided. Rotating the first adjusting threaded rod, because it is threadedly connected to the main body of the testing machine and rotatably connected to the first bearing seat, can drive the connecting frame to move up and down, thereby adjusting the height of the temperature probe assembly, so that it can accurately monitor the temperature at different positions during the extrusion process of plastic pipes, and adapt to the production of plastic pipes with different pipe diameters or extrusion processes.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 This utility model provides a technical solution: an intelligent testing machine for plastic pipe extrusion with temperature warning function, including a testing machine body 1, a first adjusting threaded rod 2, a first bearing seat 3, a connecting frame 4, a temperature probe assembly 5, a support base plate 6, a second adjusting threaded rod 7, a second bearing seat 8, a movable frame 9, a fixed box 10, a connecting pipe 11, a nozzle 12, a forward and reverse motor 13, a transmission shaft 14, a gear mechanism 15, a partition assembly 16, a feeding port 17, a sealing block 18, a guide rod 19, and a rack mechanism 20. The first adjusting threaded rod 2 is installed on the top of the testing machine body 1, and the first adjusting threaded rod 2 is connected to the testing machine body 1. The testing machine body 1 is threadedly connected, and the first adjusting threaded rod 2 is rotatably connected to the first bearing seat 3. The testing machine body 1 is equipped with an inspection door. Rotating the first adjusting threaded rod 2, because it is threadedly connected to the testing machine body 1 and rotatably connected to the first bearing seat 3, can drive the connecting frame 4 to move up and down, thereby adjusting the height of the temperature probe assembly 5, so that it can accurately monitor the temperature at different positions during the extrusion of plastic pipes, adapting to the production of plastic pipes with different pipe diameters or extrusion processes. The connecting frame 4 is installed below the first adjusting threaded rod 2 through the first bearing seat 3, and the temperature probe assembly 5 and the support base plate 6 are installed below the connecting frame 4.

[0034] A second adjusting threaded rod 7 is installed on the support base plate 6. The second adjusting threaded rod 7 is threadedly connected to the support base plate 6 and rotatably connected to the second bearing seat 8. The movable frame 9 abuts against the lower surface of the fixed box 10. Rotating the second adjusting threaded rod 7 causes the movable frame 9 to drive the fixed box 10 to move upward, so that the fixed box 10 is clamped between the movable frame 9 and the inner top of the testing machine body 1, thereby facilitating the installation and disassembly of the fixed box 10. The movable frame 9 is installed above the second adjusting threaded rod 7 through the second bearing seat 8.

[0035] A fixed box 10 is installed on the upper surface of the movable frame 9, and a connecting pipe 11 is installed on the left side of the fixed box 10. A nozzle 12 is installed at the lower end of the connecting pipe 11. The height of the nozzle 12 is greater than the height of the temperature probe assembly 5. The connecting pipe 11 is connected to the inside of the fixed box 10. The temperature probe assembly 5 facilitates the detection of the surface temperature of the plastic extrusion tube. A forward and reverse motor 13 is installed on the front surface of the fixed box 10, and a drive shaft 14 is installed at the rear end of the forward and reverse motor 13 through a bearing seat. A gear mechanism 15 is installed on the drive shaft 14. A partition assembly 16 is installed inside the fixed box 10. A spray pigment liquid is placed above the partition assembly 16. A feeding port 17 is installed on the partition assembly 16 and is located above the sealing block 18. The surface of the sealing block 18 is designed with a rubber structure. When the sealing block 18 coincides with the feeding port 17, it can seal the feeding port 17. A sealing block 18 is placed below the partition assembly 16, and a guide rod 1 passes through the sealing block 18. 9. The guide rod 19 is fixed inside the fixed box 10. The sealing block 18 is slidably connected to the guide rod 19. When the sealing block 18 is moved left and right under force, it can slide left and right along the guide rod 19, so that the sealing block 18 is more stable when moving left and right. A rack mechanism 20 is installed on the right side of the sealing block 18. The rack mechanism 20 is located above the gear mechanism 15, and the gear mechanism 15 and the rack mechanism 20 mesh with each other. When the temperature probe assembly 5 detects that the temperature of the extrusion tube is abnormal and exceeds the set temperature range, the temperature probe assembly 5 sends a signal to the control system. The control system starts the forward and reverse motor 13, which drives the transmission shaft 14 to rotate. The gear mechanism 15 installed on the transmission shaft 14 rotates accordingly. The rotation of the gear causes the rack mechanism 20 to move left and right. When the sealing block 18 moves to the right, the feed port 17 opens, and the spray pigment liquid stored above the partition assembly 16 flows to the nozzle 12 through the connecting pipe 11 and is evenly sprayed out from the nozzle 12, forming a clear mark on the surface of the plastic tube.

[0036] Working principle: When using the intelligent plastic tube extrusion testing machine with temperature warning function, firstly, the temperature probe assembly 5 constantly monitors the temperature of the plastic tube extrusion area. When the temperature probe assembly 5 detects an abnormal temperature in the extruded tube, exceeding the set temperature range, the temperature probe assembly 5 sends a signal to the control system. The control system starts the forward and reverse motor 13, which drives the transmission shaft 14 to rotate. The gear mechanism 15 mounted on the transmission shaft 14 rotates accordingly. The rotation of the gear causes the rack mechanism 20 to move left and right. When the sealing block 18 moves to the right, the feed port 17 opens, and the spray pigment liquid stored above the partition assembly 16 flows through the connecting pipe 11 to the nozzle 12 and is evenly sprayed out from the nozzle 12, forming a clear mark on the surface of the plastic tube.

[0037] Rotating the first adjusting threaded rod 2, which is threadedly connected to the testing machine body 1 and rotatably connected to the first bearing seat 3, can drive the connecting frame 4 to move up and down, thereby adjusting the height of the temperature probe assembly 5. This allows it to accurately monitor the temperature at different locations during the plastic pipe extrusion process, adapting to the production of plastic pipes with different diameters or extrusion processes. Rotating the second adjusting threaded rod 7 causes the movable frame 9 to move the fixed box 10 upward, clamping the fixed box 10 between the movable frame 9 and the inner top of the testing machine body 1, thus facilitating the installation and removal of the fixed box 10. This completes a series of operations. Content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
