[0021] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a metal powder bonding machine with a heat dissipation structure. A temperature sensor is installed below the mixing tank in the bonding machine body 1. The temperature sensor is connected to a temperature controller. The power cord of the temperature controller is plugged into a 220V power socket. The temperature sensor is connected to a circulating pump through the temperature controller. When the temperature is too high, the temperature sensor starts the circulating pump through the temperature controller. The temperature sensor can monitor the temperature of the working chamber of the bonding machine body 1 in real time. The surface of the bonding machine body 1 is integrally formed with a main material tube 4. A heat insulation sleeve 2 is fixedly connected to the surface of the bonding machine body 1. The heat insulation sleeve 2 can reduce the heat loss of the bonding machine body 1 when it is heated and stabilize the internal temperature of the bonding machine body 1.

[0024] A cooling pipe 7 is wound between the bonding machine body 1 and the insulation sleeve 2. The coolant circulating in the cooling pipe 7 carries away the heat through heat conduction, so that the internal temperature of the bonding machine body 1 drops quickly to a suitable range. A cooling fan 3 is fixedly connected to the surface of the insulation sleeve 2. The cooling fan 3 blows away the hot air on the surface of the bonding machine body 1 quickly, while prompting the surrounding cold air to quickly replenish it, forming a strong air convection, which greatly improves the heat dissipation efficiency.

[0025] The surface of the main material pipe 4 is connected to the discharge pipe 5, and the surface of the discharge pipe 5 is slidably connected to the extension pipe 6. Limiting rods 10 are inserted into both sides of the surface of the extension pipe 6. The limiting rods 10 are embedded in the surface of the discharge pipe 5. The inner surface of the extension pipe 6 is rotatably connected to the adjusting plate 12. The bonding machine body 1 is cooled by the cooling pipe 7 and the cooling fan 3, so as to ensure that the bonding process can be carried out continuously and stably within a suitable temperature range, thereby improving the bonding effect of metal powder.

[0026] A sliding extension tube 6 is provided on the surface of the discharge pipe 5, which can flexibly adjust the position and height of the inlet to adapt to receiving containers of different heights, thereby improving the stability and accuracy of discharge. A rotating adjustment plate 12 is provided in the extension tube 6 to control the discharge flow rate.

[0027] Example 2

[0028] Please see Figures 1 to 4 Based on Embodiment 1, in order to realize the relative movement and fixation between the discharge pipe 5 and the extension pipe 6, the surface of the discharge pipe 5 is provided with sliding grooves 8 on both sides. The sliding grooves 8 are rectangular grooves. The mutual cooperation between the sliding grooves 8 and the sliding block 14 realizes the mutual movement between the discharge pipe 5 and the extension pipe 6. The surface of the sliding grooves 8 is provided with multiple arrayed limiting grooves 9. The limiting grooves 9 are circular grooves. The limiting grooves 9 can realize the adjustment of multiple positions.

[0029] A sliding block 14 is slidably connected to the surface of the slide groove 8. The sliding block 14 has a square block structure. One end of the sliding block 14 is fixedly connected to the surface of the extension tube 6. Circular holes are opened on both sides of the surface of the extension tube 6, and the limiting rod 10 is slidably connected in the circular holes.

[0030] One end of the limiting rod 10 passes through the top surface of the sliding block 14 and is embedded in the limiting groove 9. A rubber groove is opened on the surface of the limiting rod 10, and a rubber strip 15 is fixedly connected to the center of the rubber groove. The two ends of the rubber strip 15 are respectively connected to the hole wall of the sliding block 14. A pull ring 11 is fixedly connected to one end of the limiting rod 10, and the pull ring 11 provides a convenient operating handle for the operator.

[0031] Example 3

[0032] Please see Figures 1 to 6 Based on Embodiment 2, in order to adjust the discharge flow rate of the discharge pipe 5, the adjustment plate 12 has a circular plate structure, and a rod groove is opened on the surface of the adjustment plate 12. A central rod 13 is fixedly connected to the surface of the rod groove. The central rod 13 has a circular plate structure with an "I" shaped cross section. The central rod 13 provides a stable rotation axis for the adjustment plate 12.

[0033] The central rod 13 passes through the top surfaces of both sides of the extension tube 6. Multiple slots 18 are provided on one end of the central rod 13. The slots 18 are semi-circular slots arranged in a circumferential array. A stop groove 16 is provided on the surface of the extension tube 6. The stop groove 16 provides rotation space for the stop post 17. The stop post 17 is rotatably connected to the surface of the stop groove 16. A rubber pad is provided on the surface of the stop post 17.

[0034] When the baffle 17 is engaged in the slot 18, the rubber pad is held between the slot 18 and the baffle 17 to prevent loosening between the baffle 17 and the slot 18. By engaging the baffle 17 in different positions of the slot 18, the adjusting plate 12 can be adjusted to various preset angles, thereby achieving precise control of the discharge flow rate.

[0035] In actual use, metal powder and resin are stirred in the working chamber. As the stirring time increases, the temperature in the working chamber rises. The temperature sensor feeds back the temperature information to the temperature controller in real time. The temperature controller starts the circulation pump in the cooling pipe 7, so that the coolant circulates in the cooling pipe 7. The coolant absorbs heat and carries the heat to the heat exchanger for cooling exchange. The control system adjusts the flow rate of the coolant in the cooling pipe 7 precisely according to the data of the temperature sensor. The cooling fan 3 automatically adjusts its speed according to the data of the temperature sensor, drawing out the hot air in the working chamber and drawing in the cold air from the outside, forming a strong air convection, reducing the temperature of the bonding chamber, and ensuring that the internal temperature of the equipment is always kept within a suitable bonding temperature range. When it is necessary to adjust the length of the discharge pipe 5, pull the pull rings 11 on both sides of the extension pipe 6. The pull rings 11 drive the limit rod 10 to move and separate from the limit groove 9. At this time, the rubber strip 15 on the surface of the limit rod 10 is subjected to tension and changes from the original state to the stretched state.

[0036] Then, slide the extension tube 6 along the surface of the discharge tube 5. After sliding to the appropriate position, align the limiting rod 10 with the corresponding limiting groove 9, release the pull ring 11, and the rubber strip 15 loses tension and returns to its original state from the stretched state, driving the limiting rod 10 to move and embed itself in the surface of the limiting groove 9. When it is necessary to control the discharge speed of the metal powder, rotate the baffle 17 to separate the baffle 17 from the groove 18 on the surface of the center rod 13. Then rotate the center rod 13. The center rod 13 drives the adjusting plate 12 to rotate and adjust to the appropriate position. Then rotate the baffle 17 around the baffle groove 16 to re-clamp the baffle 17 in the surface of the groove 18.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
