Description

Technical Field

[0001] This invention relates to the field of automated machinery technology, specifically to an automatic heat-welding machine for flower rack tubes. Background Technology

[0002] When assembling flower stand tubes, it is often necessary to connect them together by welding or other methods. People often use welding or drilling and bolting for assembly. However, the assembly process is unsightly and time-consuming, which is not conducive to the production of flower stand tubes. At the same time, when flower stand tubes are heat-welded, there may be problems such as operators moving other equipment while heat welding is being performed, causing the equipment to continue to work and affecting the use of the heat welding machine. This may result in the equipment not being able to notify personnel to shut it down in time, leading to safety accidents.

[0003] To address the issues of slow assembly and poor appearance of the flower stand tubes, as well as the lack of alarm and safety devices in the equipment, a simple optimization solution is provided. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An automatic heat-welding machine for flower stand tubes includes: support legs and a platform. The support legs are located at the lower part of the platform, and there are four support legs. The platform has a cuboid structure. The machine is characterized in that four moving rails are provided on the upper surface of the platform. Two moving rails are fixed on the left and right sides of the platform, and the other two moving rails are fixed on the same side of the platform. Clamping devices are installed on the two moving rails on the left and right sides of the platform, and heating coils are installed on the two moving rails on the same side. A fixing plate is fixed at the center of the platform, and the clamping devices are installed at the middle position of the upper surface of the fixing plate.

[0005] Preferably, the clamping device includes: a clamping cylinder, a hinge, a support frame, a telescopic rod, a hinge, a sponge, a rotating device, and a pull strap. The bottom of the clamping device is fixed to the support frame, which is fixed to the moving track or the fixed plate. The upper part of the support frame is connected to the clamping cylinder via a hinge. The clamping cylinder has a two-semi-circular structure. The bottom middle of the clamping cylinder is connected to one end of the telescopic rod via a hinge. The other end of the telescopic rod is connected to the fixed plate or the moving track. The sponge is in close contact with the inner wall of the clamping cylinder. The upper surface of the clamping cylinder is connected to both sides of the pull strap, and the other end of the pull strap is connected to the rotating device. The rotating device is fixed to the fixed plate and located on both sides of the clamping cylinder.

[0006] Preferably, the clamping device comprises three pieces, and the heating coil comprises two pieces.

[0007] Preferably, the rotating device includes: a fixed block, a through hole, a rotating shaft, a hollow tube, a rotating rod, a micro motor, and a mounting port. There are two fixed blocks, each of which is hollow inside. The rotating shaft is connected between the two fixed blocks. The center of the rotating shaft is a hollow tube. The mounting port is opened at the lower part of the rotating shaft. The left end of the hollow tube communicates with the through hole and the mounting port. The right end of the rotating shaft is connected to one end of the rotating rod, and the other end of the rotating rod is connected to the micro motor. The rotating rod and the micro motor are installed inside the fixed block at the right end.

[0008] Preferably, temperature sensors are installed at the four corners of the fixing plate. The temperature sensors are connected to the triggering device. An impact device is provided inside the triggering device. The impact device is connected to a pin. The pin is installed inside the pin guard tube. One end of the pin guard tube is connected to the triggering device housing. The other end of the pin guard tube is connected to the storage bag. The front end of the pin is installed inside the storage bag. A compression plate is installed inside the storage bag. Sodium azide is provided inside the storage bag. The tip of the pin abuts against the compression plate.

[0009] Preferably, the support frame is made of a material with a certain degree of elasticity, and the pull strap is made of plastic and is hollow inside. Beneficial effects

[0010] This invention, by setting up a clamping device, can stably control the flower stand tube during heat welding. The clamping device is lined with a sponge, which allows the heat welding of the steel tube without damaging it. At the same time, since the steel tube is heated by a heating coil, the heated steel tube can be directly squeezed by the movement of the left and right clamping devices. Finally, the two heated tubes are successfully connected together. This method and equipment are simple, can protect the integrity of the steel tube, and ensure the aesthetics of the steel tube connection.

[0011] By incorporating a clamping device and a pull strap, this invention enables the pull strap to better open and close the clamping device during use. When used in conjunction with a telescopic rod, the two components work together to ensure the stability of the clamping device during opening and closing.

[0012] This invention incorporates sodium azide. During use, a heating coil continuously heats the flower stand tube. Since the device may be unattended at times, the rising temperature is detected by a temperature sensor. This sensor triggers an impact device, which pushes a pin to strike a compression plate, causing the sodium azide in the storage bag to react and produce nitrogen gas. The nitrogen gas fills the pull strap through a hole in the fixing block. The increased pressure in the pull strap causes it to expand, and the plastic material will break upon expansion. The sound of this breakage serves as an alarm, and the released nitrogen gas will cover the heating coil, preventing a fire hazard at the flower stand tube. The loud explosion also alerts the operator to shut down the equipment, thus reducing the risk of accidents. Attached Figure Description

The upper surface of the clamping cylinder 41 is connected to one end of the pull strap 48 on both sides. The other end of the pull strap 48 is connected to the rotating device 47. The rotating device 47 is fixed to the fixed plate 5 and located on both sides of the clamping cylinder 41.

[0017] Specifically, there are three clamping devices 4 and two heating coils 6.

[0018] Specifically, the rotating device 47 includes: a fixed block 471, a through hole 472, a rotating shaft 473, a hollow tube 474, a rotating rod 475, a micro motor 476, and a mounting port 477. There are two fixed blocks 471, and each fixed block 471 is hollow inside. The rotating shaft 473 is connected between the two fixed blocks 471. The center of the rotating shaft 473 is the hollow tube 474. The mounting port 477 is opened at the lower part of the rotating shaft 473. The left end of the hollow tube 474 is connected to the through hole 472, and the hollow tube 474 is connected to the mounting port 477.

[0019] Specifically, temperature sensors 51 are installed at the four corners of the fixing plate 5. The temperature sensors 51 are connected to the triggering device 52. An impact device 53 is provided inside the triggering device 52. The impact device 53 is connected to a pin 54. The pin 54 is installed inside the pin guard 55.

[0021] Working principle: An automatic heat-jointing machine for flower stand pipes includes: support legs 1 and platform 2. The support legs 1 are located at the lower part of the platform, and there are four support legs 1. The platform structure is a cuboid structure. When working, the steel pipe is placed in the clamping device 4 in the middle. The clamping device clamps the steel pipe tightly. Then, the other two steel pipes can be clamped by the left and right clamping devices 4. Before clamping, the heating coil 6 is moved. The steel pipe passes through the heating coil 6. The heating coil 6 is activated and moves the left and right clamping devices 4 towards the middle through the left and right moving tracks 3 to squeeze the steel pipe. When the steel pipe reaches a certain temperature, the two steel pipes are heated and joined together under the action of the squeezing force, and the work is completed. When the equipment is in operation, there may be situations where workers are no longer near it for other reasons. In this case, if the heating coil 6 continues to heat the flower rack tube, it could lead to a safety accident. However, since temperature sensors 51 are installed at each of the four corners of the fixing plate 5, if the temperature continues to rise, the temperature sensors 51 will transmit signals to the triggering device 52. The triggering device 52 will then issue a command to control the impact device 53. The impact device 53 will push the ejector pin 54 forward, and the ejector pin 54 will move along the ejector pin guard tube 55, pushing the storage... The compression plate 57 inside the package 56 impacts the sodium azide 58, causing the sodium azide 58 to react and produce nitrogen gas. The generated nitrogen gas will flow along the through hole 472 in the fixed block 471 to the hollow tube 474 of the rotating shaft 473, and then flow through the mounting port 477 from the hollow tube 474 into the pull belt 48, causing the pull belt to expand and produce a popping sound, notifying the operator to pay attention to the status of the equipment. At the same time, the pull belt 48 will disconnect, releasing the internal nitrogen gas. The nitrogen gas covers the heating coil 6 to prevent the equipment from being affected by fire and ensure the safety of the equipment.

[0022] Subsequent use only requires replacing the storage bag and pull strap to resume normal production.

[0023] The specific embodiments described in this invention do not constitute a limitation on the scope of this application. Any modifications that can be made by those skilled in the art within the spirit and principles of this invention should be considered as being included within the protection scope of this invention.
