Description

Technical Field

[0001] The utility model relates to the field of powder modification, in particular to a high-efficiency bonding machine. Background Art

[0002] The bonding machine is used to bond two materials together evenly, such as bonding metal powder to small plastic particles. The main process is to first mix the two powder materials evenly through high-speed stirring, then put them into the bonding machine for low-speed stirring and heat to a certain temperature and keep it at a constant temperature for a few minutes before cooling. The temperature here is obtained through repeated tests based on the melting point and other properties of the material. In the prior art, high-speed stirring machines are often used for bonding operations, but the efficiency is average. Therefore, the applicant thought of using the modification machine disclosed in the Chinese patent application number 201420628185.6 for bonding operations. However, if the modification machine is directly used for bonding, there are the following problems: Figure 6 As shown in the figure, the distance between the upper part of the inner cavity of the mixing drum of the equipment and the paddle wheel is very large, and it is easy for materials to accumulate in these places. When the new mixed material enters the mixing drum from the feed port for bonding, the uneven accumulation will fall and mix into the uniform material. In addition, the accumulated material has been on the wall of the drum, and the temperature is higher than that of the new material, which will cause asynchronous heating. In the short heating and bonding process of a few minutes, it is very easy to cause uneven bonding of the final finished product, resulting in work delays and time losses. If the material in the mixing drum becomes sticky, it is necessary to stop the work and clean the mixing drum. This greatly reduces production efficiency and has high production costs.

[0003] Therefore, there is an urgent need for an efficient binding machine that can greatly reduce the generation of material accumulation in the mixing drum, keep the bonded product uniform, reduce the frequency of cleaning the mixing drum, improve production efficiency, and reduce production costs. Summary of the invention

[0004] The utility model aims to provide an efficient binding machine, which can greatly reduce the generation of material accumulation in the mixing drum, keep the bound products uniform, reduce the frequency of cleaning the mixing drum, improve production efficiency and reduce production costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency bonding machine, including a bonding module, the bonding module including a mixing drum, a heater and a plurality of agitators, the agitator is arranged in the inner cavity of the mixing drum, the heater heats the material in the mixing drum, the inner cavity is composed of two intersecting cylindrical cavities with parallel axes, the agitator includes two groups of paddle wheel assemblies arranged one-to-one corresponding to the two cylindrical cavities, the axis of the rotating shaft of the paddle wheel assembly is colinear with the axis of the cylindrical cavity, the paddle wheel assembly is close to the cavity wall of the inner cavity, and the paddle wheel assembly scrapes off the material on the cavity wall of the inner cavity when it rotates.

[0006] Since the inner cavity is composed of two intersecting cylindrical cavities with parallel axes, the paddle wheel assembly will scrape the material of the cavity wall when it rotates, greatly reducing material accumulation, ensuring that the product after bonding is uniform, and the frequency of cleaning the mixing drum is getting less and less, which greatly improves production efficiency and reduces production costs.

[0007] Preferably, the distance between the paddle wheel assembly and the cavity wall of the inner cavity is 0.5~3mm. The mixing drum will expand inward when heated. If the distance is too small, the friction between the paddle wheel assembly and the cavity wall of the inner cavity will generate a lot of heat, resulting in unstable temperature inside the bonding machine, affecting the bonding quality and even causing the bonded product to be unqualified. If the distance is too large, more material will be accumulated. Setting the distance of 0.5~3mm can prevent the above two situations from occurring.

[0008] Preferably, each group of the paddle wheel assemblies includes a plurality of paddle wheels evenly arranged in the axial direction, and each paddle wheel includes a plurality of blades evenly arranged in the circumference. Increasing the number of paddle wheels further improves the working efficiency of a single bonding machine.

[0009] Preferably, the bonding module includes a driving motor, the driving motor is provided with an output wheel, one end of each rotating shaft extends outside the mixing drum and is provided with an input wheel, and power is transmitted to the rotating shaft through a transmission belt provided on the output wheel and the two input wheels. One driving motor drives two input wheels at the same level to ensure that the two input wheels rotate synchronously, and the blades of the two paddle wheels will not interfere with each other to avoid collision.

[0010] Preferably, a feeding module is connected to the upper part of the feeding port, and the feeding module is provided with a feeding valve, which can control the feeding rhythm.

[0011] Preferably, a discharge valve is provided below the mixing drum, and a discharge module is provided below the discharge valve.

[0012] Preferably, the mixing drum is provided with a temperature measuring device, which monitors the temperature of the mixing drum and ensures a constant temperature state in the mixing drum.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Since the inner cavity is composed of two intersecting cylindrical cavities with parallel axes, the paddle wheel assembly will scrape off the material on the cavity wall when it rotates, greatly reducing the accumulation of materials, ensuring the uniformity of the product after bonding, and reducing the frequency of cleaning the mixing drum, which greatly improves production efficiency and reduces production costs.

[0015] 2. The friction between the paddle wheel assembly and the inner wall of the mixing drum is avoided, and the temperature inside the mixing drum can be better controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 and Figure 3As shown, a high-efficiency bonding machine of this embodiment includes a bonding module 2, and the bonding module 2 includes a mixing drum 5, a heater 21 and a plurality of stirrers 6. The stirrer 6 is arranged in the inner cavity 7 of the mixing drum 5, and the heater 21 heats the material in the mixing drum 5. The inner cavity 7 is composed of two intersecting cylindrical cavities with parallel axes. The stirrer 6 includes two groups of paddle wheel assemblies 8 arranged one by one with the two cylindrical cavities. The axis of the rotating shaft 9 of the paddle wheel assembly 8 is colinear with the axis of the cylindrical cavity. The paddle wheel assembly 8 is close to the cavity wall of the inner cavity 7. When the paddle wheel assembly 8 rotates, the material on the cavity wall of the inner cavity 7 is scraped off. Since the inner cavity 7 is composed of two intersecting cylindrical cavities with parallel axes, the paddle wheel assembly 8 will scrape off the material on the cavity wall when it rotates, and the accumulation of materials is greatly reduced, which can ensure that the product after bonding is uniform, and the frequency of cleaning of the mixing drum 5 is getting less and less, which greatly improves the production efficiency and reduces the production cost. The distance between the paddle wheel assembly 8 and the cavity wall of the inner cavity 7 is 0.5~3mm. The friction between the paddle wheel assembly 8 and the inner wall of the mixing drum 5 is avoided, and the temperature in the mixing drum 5 can be better controlled.

[0026] like Figure 1 , Figure 2 and Figure 4 Each set of paddle wheel assemblies 8 includes a plurality of paddle wheels 11 evenly arranged in the axial direction. In this embodiment, three paddle wheels 11 are preferably used. Each paddle wheel 11 includes four blades 12 evenly arranged on the circumference. The bonding module 2 also includes a driving motor 13, which is provided with an output wheel 14. One end of each rotating shaft 9 extends outside the mixing drum 5 and is provided with an input wheel 15. The power is transmitted to the rotating shaft 9 through a transmission belt 16 provided on the output wheel 14 and the two input wheels 15. The mixing drum 5 is provided with a feed port 10, and the upper part of the feed port 10 is connected to the feed module 1, and the feed module 1 is provided with a feed valve. A discharge valve 19 is provided below the mixing drum 5, and a discharge module 3 is provided below the discharge valve 19.

[0027] like Figure 2 and Figure 5 As shown, the mixing drum 5 is provided with a guide wheel 17, and the transmission belt 16 first passes through the guide wheel 17 and then wraps around the two input wheels 15, which can increase the wrap angle to improve the transmission efficiency. One drive motor 13 drives the two input wheels 15 at the same level to ensure that the two input wheels 15 rotate synchronously, and the blades 12 of the two paddle wheels 11 will not interfere with each other when rotating to avoid collision.

[0028] like Figure 1 and Figure 3As shown, the driving motor 13, the feed valve and the discharge valve 19 are all connected to the control module 4, and the feed valve and the discharge valve 19 can well control the rhythm of feeding and discharging through the control module 4. The control module 4 has a manual mode and an automatic mode. A temperature measuring device 20 is provided outside the mixing drum 5, and heaters 21 are provided at both ends of the mixing drum 5 and on the drum wall. The heater 21 is heated, and the temperature measuring device 20 detects the temperature of the mixing drum 5 and feeds it back to the control module 4 in time. The control module 4 controls the heater 21 accordingly, and can ensure a constant temperature state in the mixing drum 5.

[0029] Working principle:

[0030] The two materials, which have been stirred at high speed, enter the mixing drum 5 through the feeding module 1 for low-speed bonding. The two paddle wheel assemblies 8 rotate synchronously, the heater 21 heats the mixing drum 5, and the temperature measuring device 20 measures the temperature and transmits it to the control module 4, so that the mixing drum 5 is kept at a constant temperature for a few minutes, and then the finished product is discharged from the discharge valve 19 for cooling. It should be pointed out that since the inner cavity 7 is composed of two intersecting cylindrical cavities with parallel axes, the paddle wheel assembly 8 will scrape the material of the cavity wall when it rotates, greatly reducing the accumulation of materials.

[0031] As described above, the utility model provides a high-efficiency bonding machine. Since the inner cavity is composed of two intersecting cylindrical cavities with parallel axes, the paddle wheel assembly will scrape the material of the cavity wall when it rotates, greatly reducing the accumulation of materials, ensuring the uniformity of the bonded products, and reducing the frequency of cleaning the mixing drum, which greatly improves production efficiency and reduces production costs. It also avoids friction between the paddle wheel assembly and the inner wall of the mixing drum, can better control the temperature in the mixing drum, and further improves the bonding quality.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
