Description

Technical Field

[0001] The utility model relates to the technical field of welding rod processing equipment, in particular to an automatic welding rod packaging machine. Background Art

[0002] As we all know, welding rods are composed of two parts: welding core and coating. Welding rods are made by evenly and centripetally pressing the coating (coating) onto the welding core outside the metal welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially the content of harmful impurities (such as sulfur, phosphorus, etc.), which should be strictly restricted and better than the parent material. The composition of the welding core directly affects the composition and performance of the weld metal, so the harmful elements in the welding core should be as small as possible. In recent years, with the rapid development of society, the demand for welding rods has increased day by day, and people have put forward higher requirements for the automatic processing production line of welding rods. At present, in the processing and production process of welding rods, the processed welding rods need to be packaged and transported. At present, the traditional packaging process adopts the manual packaging method, that is, a certain number of welding rods are regularized by manpower, and then packed into the packaging box for packaging.

[0003] For example, a patent with the national authorized patent announcement number CN206107722U discloses an automatic packaging machine for welding rods, which relates to the technical field of welding rod processing equipment, including: a climbing conveying mechanism, a horizontal conveying mechanism, and a counting mechanism. The climbing conveying mechanism includes a climbing conveyor belt and a motor; the horizontal conveying mechanism includes a horizontal conveyor belt and a motor; the counting mechanism includes a cache box located below the tail end of the horizontal conveyor belt, and a photoelectric counter is provided on the side wall of the cache box. Electric control doors are respectively provided at the welding rod inlet and outlet of the cache box, and the photoelectric counter is electrically connected to the enabling terminals of the two electric control doors through a trigger; a packing conveyor belt is provided below the welding rod outlet of the cache box, and a clamping member for receiving the welding rod is provided on the packing conveyor belt, and a card slot is provided on the clamping member; sorting conveyor belts are symmetrically provided on both sides of the horizontal conveyor belt; the two sorting conveyor belts are in a trumpet-shaped structure with a closed end along the direction of welding rod transmission; tightening cylinders are symmetrically provided on both sides of the packing conveyor belt.

[0004] However, the above-mentioned automatic packaging machine for welding rods will make the heads of the welding rods inconsistent in orientation during the process of conveying and packaging the welding rods, and it does not have the function of turning them to a consistent orientation, which will cause confusion in the direction of the heads of the welding rods when packaging, making it inconvenient for workers to take them out of the box for use. Utility Model Content

[0005] The utility model aims to provide an automatic welding rod packaging machine to solve the problem that the welding rod heads are not oriented in the same direction and cannot be turned to have the same direction during the welding rod conveying and packaging process proposed in the background technology.

[0011] Preferably, the models of the controller and the photoelectric sensor are E3JK-DS30M1 and SIMATIC S7-1200 respectively.

[0012] Preferably, a second electric push rod is fixedly mounted on one end of the mounting tube, a limit frame is fixedly mounted on one end of the piston rod of the second electric push rod, and the limit frame can slide vertically from the outer surface of the mounting tube to the lower end of the limit frame.

[0013] Preferably, the limit frame can push and straighten the welding rod that is deflected by magnetic suction.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the design of the extraction mechanism, the cross slide, the conveying equipment and the storage frame, in the process of quantitative extraction and packaging of the welding rods, the extraction mechanism on the lower surface of the moving block can be driven to move to the top of the storage frame by starting the cross slide, and then the extraction mechanism can be started to extend into the storage frame and the metal core of the welding rod exposed at the outer end can be attracted and inserted through magnetism, and this attraction of the metal core of the welding rod exposed at the outer end can also ensure that the head of the welding rod is magnetically attracted to face the lower end, so that the head of the welding rod is in the same direction, and then the cross slide can drive the extraction mechanism to move to the top of the conveying equipment and then start the extraction mechanism again to insert the welding rod into the packaging box and turn off the magnetic attraction, thereby completing the quantitative storage operation of the welding rod, and along with the conveying of the conveying equipment, it can be transported to the packaging equipment for the cover packaging operation.

[0017] The photoelectric sensor installed in the magnetic suction slot can also detect the characteristics of the head and tail of the welding rod to determine its direction.

[0025] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0027] The conveying device 1 is a conveyor belt, and the conveying device 1 can convey the packaging box and allow the extraction mechanism 2 to store the welding rod.

[0028] Through the design of the extraction mechanism 2, the cross slide 102, the conveying device 1 and the storage frame 3, during the process of quantitative extraction and packaging of the welding rods, the extraction mechanism 2 on the lower surface of the moving block 103 can be driven to move to the top of the storage frame 3 by starting the cross slide 102, and then the extraction mechanism 2 can be started to extend into the storage frame 3 and the metal core of the welding rod exposed at the outer end can be attracted and inserted by magnetism, and this attraction of the metal core of the welding rod exposed at the outer end can also ensure that the magnetically attracted welding rod head faces the lower end, so that the head direction of the welding rod can be consistent, and then the cross slide 102 can drive the extraction mechanism 2 to move to the top of the conveying device 1 and then start the extraction mechanism 2 again to insert the welding rod into the packaging box and turn off the magnetic attraction, thereby completing the quantitative storage operation of the welding rod, and along with the conveying of the conveying device 1, it can be transported to the packaging device for the cover packaging operation.

[0029] like Figure 3-Figure 4 As shown, the extraction mechanism 2 includes a first electric push rod 201, a mounting cylinder 202 is fixedly installed on the lower surface of the piston rod of the first electric push rod 201, a controller 203 is fixedly installed in the mounting cylinder 202, a connecting disk 207 is fixedly installed on the lower surface of the controller 203, and a plurality of groups of magnetic attraction grooves 204 are provided on the lower surface of the connecting disk 207, and each group of magnetic attraction grooves 204 is electrically connected separately by the controller 203.

[0030] The magnetic attraction groove 204 can magnetically attract and insert the metal core in the middle part of the welding rod, and a photoelectric sensor 208 is arranged in each group of magnetic attraction grooves 204. The signal transmitting end of the photoelectric sensor 208 is connected to the signal receiving end of the controller 203, and the control output end of the controller 203 is electrically connected to the electrical control end of multiple groups of magnetic attraction grooves 204.

[0031] The models of the controller 203 and the photoelectric sensor 208 are E3JK-DS30M1 and SIMATIC S7-1200 respectively.

[0032] A second electric push rod 205 is fixedly mounted on one end of the mounting cylinder 202 , and a limit frame 206 is fixedly mounted on one end of the piston rod of the second electric push rod 205 . The limit frame 206 can slide vertically from the outer surface of the mounting cylinder 202 to the lower end of the limit frame 206 .

[0033] The limit frame 206 can push and straighten the welding rod that is deflected by the magnetic suction.

[0034] Through the design of the first electric push rod 201, the mounting tube 202, the controller 203, the magnetic suction groove 204, the second electric push rod 205, the limit frame 206 and the connecting disk 207, in the process of quantitative extraction and packaging of the welding rod, the first electric push rod 201 on the lower surface of the moving block 103 can be driven to move to the top of the storage frame 3 by starting the cross slide 102, and then the first electric push rod 201 can be started to push the connecting disk 207 in the mounting tube 202 on the lower surface to extend into the storage frame 3, and then the controller 203 can supply electricity to generate magnetism to the magnetic suction groove 204, so that the connecting disk 207 can attract the metal core leaking out of the outer end of the welding rod through the magnetic force in the magnetic suction groove 204, because the metal core wrapped in the welding rod is subjected to a smaller magnetic attraction force, and thus the magnetic suction groove 204 can be ensured to attract the metal core leaking out of the outer end of the welding rod, so as to ensure that the head of the welding rod is in the same direction;

If the direction is wrong, it will send a signal to the controller 203, and the controller 203 will individually control a certain magnetic suction slot 204 to turn off the power supply and release the magnetic attraction, thereby ensuring that the welding rods on the suction are in the same direction. Then the second electric push rod 205 can be started to push the limit frame 206, and the limit frame 206 can push and straighten the deflected welding rod, and then the cross slide 102 can drive the welding rod to move to the top of the conveying device 1 and then start the first electric push rod 201 again to insert the welding rod into the packaging box and turn off the magnetic attraction of the magnetic suction slot 204 through the controller 203, thereby completing the quantitative storage operation of the welding rod, and along with the conveying of the conveying device 1, it can be transported to the packaging device for closing and packaging.
