Description

Technical Field

[0001] The present invention relates to the technical field of drying machines, in particular to a solder drying machine for steel welding. Background Art

[0002] Solder dryer is mainly used to remove moisture and volatile substances from solder to prevent pores and spatter during soldering, while extending the life of solder and preventing solder oxidation and deterioration.

[0003] During operation, a solder dryer uses a stirring mechanism within the heating chamber to keep the solder in constant contact with a heated roller. The roller then outputs heat to dissipate moisture and volatile substances within the solder. However, during this drying process, heat transfer is limited, and moisture and volatile substances are expelled through natural evaporation (which is slow), resulting in low drying efficiency.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0005] In response to the above-mentioned defects, the purpose of the present invention is to provide a solder dryer for steel welding, which realizes airflow feeding, and the heat is combined with the airflow to improve the drying efficiency of the material. At the same time, the barrier plate switches its state according to the amount of feeding to change the spatial layout in the heating chamber, thereby further improving the uniformity and drying efficiency of the material.

[0006] In order to achieve the above-mentioned objectives, the present invention provides a solder dryer for steel welding, comprising a storage bin and a heating bin arranged on a frame, an air flow feeding component that drives the material from the storage bin into the heating bin, and a heating component arranged in the heating bin for heating the material in the bin; a gathering type discharge port is provided below the heating bin, and a movable blocking component is provided at its opening; an exhaust port is provided on the bin wall of the heating bin; a blocking support plate is movably provided in the heating bin, which is connected to a driving component; in the early stage of feeding, the periphery of the blocking support plate contacts the side wall near the gathering type discharge port to divide the internal space of the heating bin into a space to be released near the gathering type discharge port and a main heating space with a heating component; in the late stage of feeding, the blocking support plate cancels the blocking work, so that the space in the heating bin is unified.

[0007] According to the solder dryer for steel welding of the present invention, the airflow feeding assembly includes an air feeder and an air duct connected to its output end; the air duct extends into the storage bin and is further connected to the heating bin wall; a feed port is provided on the local air duct located in the storage bin.

[0008] According to the solder dryer for steel welding of the present invention, a material recycler is installed at the exhaust port, which has an upward air port and a downward return port; the lower side of the return port corresponds to the feed port of the storage bin.

[0009] According to the solder drying machine for steel welding of the present invention, there is a height difference H between the air inlet and the exhaust port provided in the heating chamber, and the center distance between the two is greater than the sum of the two diameters.

[0010] According to the solder dryer for steel welding of the present invention, a blocking member is further provided in the heating chamber to reduce the discharge of materials carried by the airflow from the exhaust port; the blocking member is arranged between the air inlet and the exhaust port; the blocking member is a flat plate structure, and a plurality of air holes for air flow to pass through are distributed on its plate surface.

[0011] According to the solder drying machine for steel welding of the present invention, the blocking support plate is a concave structure with the concave surface facing the material gathering type discharge port.

[0012] According to the solder drying machine for steel welding of the present invention, the blocking support plate is connected to a lifting rod that moves in the direction of the material-gathering discharge port; the moving lifting rod further drives the blocking support plate to switch its state.

[0013] According to the solder dryer for steel welding of the present invention, a positioning structure for positioning the moving position of the lifting rod is provided on the wall of the heating chamber; when the blocking tray is in the blocking state, the positioning structure locks the position of the lifting rod; when the blocking tray switches the state, the positioning structure cancels the positioning work, and the lifting rod is moved and reset by the action of an elastic member.

[0015] The present invention provides a solder dryer for steel welding, comprising a material storage bin and a heating bin mounted on a frame, an airflow feed assembly that propels material from the storage bin into the heating bin, and a heating assembly mounted within the heating bin to heat the solder within the bin. The heating assembly utilizes a heating roller, although other heating structures, such as heating electrodes or heating coils, may also be employed.

DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1 and Figure 2The present invention provides a solder dryer for steel welding. The solder dryer comprises a storage bin 1 and a heating bin 2 mounted on a frame, an airflow feed assembly for driving material from the storage bin 1 into the heating bin 2, and a heating assembly disposed within the heating bin 2 for heating the interior of the bin. In this embodiment, the heating assembly utilizes a heating roller, but other types of heating structures, such as a heating electrode or a heating coil, may also be employed.

[0024] During operation, the material to be dried (solder) is poured into storage bin 1. The airflow generated by the airflow feed assembly carries the solder to heating bin 2, where the heating assembly generates heat to achieve drying. During the drying process, the material is quantitatively transported to heating bin 2 from scratch, and the heat generated by the heating assembly complements the airflow generated by the airflow feed assembly. This ensures more comprehensive contact between the material and the heat within heating bin 2, while also accelerating the expulsion of moisture (water vapor or other volatile gases), thereby improving drying efficiency.

[0025] The airflow feed assembly includes an air supply 21 (e.g., a blower) and an air conduit 22 connected to its output end. The air conduit 22 extends into the storage bin 1 and further connects to the wall of the heating bin 2. A feed port is defined on the local air conduit 22 within the storage bin 1. During operation, the air supply 21 generates airflow that travels along the air conduit 22. When the airflow reaches the storage bin 1, it absorbs the material (according to the Bernoulli principle) and carries it, ultimately entering the heating bin 2.

[0026] A gathering-type discharge port 3 is located below the heating chamber 2. Its peripheral sidewalls form a tapered structure centered around the discharge port, effectively gathering the material during discharge. A movable blocking assembly is located at the opening. This blockage seals the gathering-type discharge port 3 during feeding and drying operations. When discharge begins, the blockage is lifted (opening the gathering-type discharge port 3). This movable blocking assembly is a pull-out baffle plugged into the heating chamber 2.

[0027] The heating chamber 2 has an exhaust port on its wall, through which the airflow in the heating chamber 2 is discharged.

[0028] Considering that during the feeding process, materials that preferentially enter the heating chamber 2 will first be placed at the bottom of the chamber (located at the material-gathering discharge port 3), away from the heating components and placed in a small space, resulting in slow heat transfer and uneven drying. To address this, the heating chamber 2 of the present application is provided with a movable barrier support plate 4 connected to a drive assembly;

[0029] In the early stage of feeding, the periphery of the blocking support plate 4 contacts the side wall near the aggregate type discharge port 3, so as to divide the internal space of the heating chamber 2 into a to-be-released space 6 near the aggregate type discharge port 3 and a main heating space 5 with a heating component ( Figure 5 As shown), that is, in the early stage of feeding, the material will not enter the space to be released 6, but only exist in the main heating space 5 with a larger cross-sectional area, close to the heating component to increase the heating efficiency.

[0030] In the late stage of feeding, in order to ensure the space utilization of the heating bin 2, the blocking support plate 4 cancels the blocking work, so that the space in the heating bin 2 is unified, and the dried material re-enters the space to be released 6.

[0031] Specifically, the blocking support plate 4 is connected to a lifting rod 61 that moves in the direction of the aggregate discharge port 3; the moving lifting rod further drives the blocking support plate to switch its state. A positioning structure for positioning the moving position of the lifting rod 61 is provided on the wall of the heating chamber 2. The positioning structure includes a positioning slot 71 provided at a predetermined position of the lifting rod 61 and a latch 72 installed in the heating chamber 2. The latch 72 has a retractable output end. In the positioning state, the output end of the latch 72 extends and engages with the positioning slot 71 of the lifting rod 61, thereby positioning the lifting rod 61.

[0032] When the blocking tray 4 is in the blocking state, the lifting rod 61 is in the lower state, and the positioning structure locks the position of the lifting rod 61; when the blocking tray 4 switches its state, the positioning structure cancels the positioning work, and the lifting rod 61 is moved and reset by an elastic member 62 (the lifting rod 61 resets to the upper state).

[0033] In order to ensure the barrier effect of the barrier plate 4 and prevent it from carrying materials during its rising process, the barrier plate 4 is a concave structure with the concave surface facing the material-gathering discharge port 3. During the rising process of the barrier plate 4, the material falls due to the poor supporting effect of the concave structure.

[0034] Preferably, in order to avoid the discharged air flow from carrying out secondary materials (carrying out materials that should be stored in the heating bin 2), a material recoverer 30 is installed at the exhaust port, which has an upward air port 31 and a downward return port 32; when the air flow enters the material recoverer 30, the lighter air flow will be discharged upward from the air port 31, while the heavier material will be discharged downward from the return port 32. The lower part of the return port 32 corresponds to the feed port of the storage bin 1, and the material discharged downward falls into the storage bin 1 and is carried and fed again.

[0035] In addition, in order to further avoid secondary carrying of materials, a blocking member is provided in the heating chamber 2 to reduce the amount of airflow carrying materials discharged from the exhaust port; the blocking member is provided between the air inlet and the exhaust port (there is a height difference H between the air inlet and the exhaust port of the heating chamber 2, and the center distance between the two is greater than the sum of the diameters of the two, Figure 3 As shown); the blocking member is a flat plate structure, and a plurality of air holes for air flow are distributed on its plate surface.

[0036] In the first embodiment, the blocking member may be a mesh filter structure. It should be noted that the shape of the air holes may be adaptively adjusted.

[0037] See also Figure 4 In this embodiment, the elastic member 62 has a planar spiral structure, with its inner end connected to the barrier plate 4 and its outer end connected to the wall of the heating chamber 2. In addition to driving the lifting rod 61 to reset, this elastic member 62 also serves the following purpose: during the early stages of feeding, the barrier plate 4 stretches the elastic member 62 into a conical spiral structure. In this state, the elastic member 62 acts as a material barrier (reducing the material flow rate) during the feeding process, somewhat increasing the contact time between the material and the airflow. Furthermore, the elastic member 62, positioned around the heating roller, acts as a heat conductor, assisting in the downward transfer of heat and optimizing the drying effect.

[0038] At the late stage of feeding, the elastic member 62 is restored to the planar spiral structure. In this state, the elastic member 62 also acts as a blocking member, which uses the blocking airflow to carry the material for the second time.

[0039] Preferably, in order to prevent the lifting rod 61 from rising too quickly, a damper is provided on the heating chamber 2 to limit the rising speed of the lifting rod 61. The damper can be a damping gasket (rubber gasket) or a damping roller or other damping structure.

[0040] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
