Description

Technical Field

[0001] The invention relates to the technical field of welding material management equipment, in particular to a dispensing and recycling machine for a welding rod baking chamber. Background Art

[0002] Welding rods are commonly used welding materials for equipment, pipelines, steel structures, machinery, etc. All welding rods used should be baked before being put into use. After passing the baking test, welders will go to the welding rod baking room to collect them. The welding rod bakers will register the welding rod issuance and recovery ledger. If the welder does not use up the welding rods collected that day, the welding rods need to be returned to the baking room. When the bakers issue and recover the registration ledger, the quantity is registered in "roots" as the unit. It is strictly forbidden to register in "barrels", "bags", "kilograms", "jins or kilograms", otherwise the welding work will be out of control.

[0003] The traditional method of counting the number of welding rods for distribution and recycling is to count them manually or estimate the number of welding rods by weighing. Manual counting is slow. Every morning, noon and evening, welders have to queue up in long lines to collect welding materials and return the remaining welding rods after get off work. This takes a long time and affects welding or off-duty time, which delays the construction period and is not convenient for welding material recycling management, indirectly affecting the quality of welding.

[0004] Welding rods are distributed and recovered by estimating the number of electrodes by weighing. There are tens of thousands of materials for welding rods, and the commonly used diameters are 2mm, 2.5mm, 3.2mm, 4mm, 5mm, etc. The coatings are also divided into acidic and alkaline. Therefore, different materials have different densities, and different densities, different diameters, and different coatings will result in different numbers of electrodes of the same weight. In order to find out how many welding rods there are per unit weight, the labor intensity of the welding rod bakers is greatly increased. For this reason, we propose a distribution and recovery machine for welding rod baking rooms. Summary of the invention

[0052] Embodiment 2:

[0053] See also Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12On the basis of Example 1, a guide barrel 18 is installed at the bottom of the inner cavity of the welding rod barrel 17. The guide barrel 18 is the same length as the welding rod barrel 17 and the opening is upward. The side wall of the guide barrel 18 is evenly provided with openings 19 (the openings 19 are located on the side wall of the guide barrel 18, and the top of the openings 19 are located below the top of the guide barrel 18, and the bottom of the openings 19 are located above the bottom of the guide barrel 18). An elastic member 25 is installed at the bottom of the inner cavity of the guide barrel 18, and a support block is installed at the top of the elastic member 25. The support block can slide up and down in the inner cavity of the guide barrel 18. A hopper 20 is installed on the top wall of the guide barrel 18 to guide the falling welding rod 10 to ensure that the welding rod 10 enters the inner cavity of the guide barrel 18;

[0054] The support block includes a support block 26 installed on the top of the elastic member 25, a placement groove is provided on the top wall of the support block 26, a moving block 27 is slidably inserted in the inner cavity of the placement groove, and the moving block 27 can move up and down in the inner cavity of the placement groove, an elastic element is installed between the bottom of the inner cavity of the placement groove and the bottom wall of the moving block 27, a support block 28 is installed on the top wall of the moving block 27, the support block 28 is an upward conical block, a touch switch 29 is installed on the bottom wall of the inner cavity of the placement groove, a winding motor 31 is installed at the bottom of the inner cavity of the welding rod barrel 17, the winding motor 31 is electrically connected to the touch switch 29 through a wire, a pull rope 30 is wound around the output shaft of the winding motor 31, and one end of the pull rope 30 away from the output shaft of the winding motor 31 is connected to the bottom wall of the support block 26;

[0055] When the welding rod 10 falls, the welding rod 10 enters the inner cavity of the guide barrel 18 after being guided by the hopper 20, and the bottom end of the welding rod 10 contacts the support block 28. The support block 28 is pushed downward by pressure, which causes the support block 26 to move downward, compressing the elastic member 25, playing a buffering and decompression effect, reducing the impact force on the welding rod 10 when it falls, protecting the welding rod 10, and the support block 28 moves downward, causing the moving block 27 to move into the inner cavity of the placement groove, touching the opening The switch 29 is pressed to energize the winding motor 31, and the pull rope 30 is wound around the output shaft of the winding motor 31, and the support block 26 and the support block 28 are moved downward, so that the welding rod 10 is moved downward until the welding rod 10 passes through the opening 19 and enters the inner cavity of the welding rod barrel 17 (the support block 28 is conical, so that the welding rod 10 directly passes through the opening 19). At this time, the pressure on the support block 28 disappears and moves upward, so that the pressure on the touch switch 29 disappears, and the winding motor 31 is disconnected. Electricity (after the winding motor 31 is powered off, the output shaft is not locked and can rotate), under the action of the elastic member 25, the support block 26 and the support block 28 move up and reset, and then repeat the operation, the welding rods 10 enter the guide barrel 18 one by one, and then enter the inner cavity of the welding rod barrel 17, so that the welding rod 10 will not contact and rub with the previous welding rod 10 during the feeding process, avoiding damage to the coating on the surface of the welding rod 10 (the welding rod 10 directly enters the inner cavity of the welding rod barrel 17 for winding and releasing. First, there is a certain distance between the welding rod 10 and the welding rod barrel 17. The falling of the welding rod 10 will bring a certain impact, which will cause the welding rod 10 to be impacted, which is easy to cause damage to the welding rod 10, and the welding rod 10 enters the inner cavity of the welding rod barrel 17 one by one. During the falling process, the welding rod 10 will directly contact the welding rod 10 in the inner cavity of the welding rod barrel 17, resulting in severe friction between the welding rods 10, which is easy to cause damage to the coating on the surface of the welding rod 10);

[0056] See also Fig. 9 A driving motor 21 is installed on the top wall of the welding rod barrel 17, a connecting rope 22 is wound around the output shaft of the driving motor 21, a pressing ring 23 (the pressing ring 23 is made of metal and has a certain weight) is installed at one end of the connecting rope 22 away from the output shaft of the driving motor 21, the pressing ring 23 is sleeved on the outside of the guide barrel 18, and the outer wall of the pressing ring 23 is wrapped with an elastic layer 24 of rubber material;

[0057] The driving motor 21 works to release the connecting rope 22, so that the pressing ring 23 moves downward, and the welding rod 10 falling into the inner cavity of the welding rod barrel 17 is squeezed toward the edge of the welding rod barrel 17 (when the welding rod 10 enters the inner cavity of the welding rod barrel 17, the welding rod 10 is inclined against the inner cavity of the welding rod barrel 17);

[0058] Compared with Example 1, components such as a guide barrel 18 are added to reduce the impact on the welding rod 10 when it is dropped and protect the welding rod 10. The welding rods 10 fall one by one and are separated by the guide barrel 18, so that the welding rods 10 will not come into contact with the previous welding rods 10 during the falling process, thereby preventing the newly fallen welding rod 10 from rubbing against the previous welding rod 10 and damaging the coating on the surface of the welding rod 10.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
