Description

Technical Field

[0001] The present application relates to the field of automated packaging equipment, and in particular to an automatic weighing and stepping packaging production line for welding rods. Background Art

[0002] Welding rods are metal strips that are melted and filled in the joints of welding workpieces. They are widely used in gas welding or electric welding. With the continuous advancement of science and technology, the production efficiency of welding rods has been significantly improved, and has gradually improved from manual operation to automation.

[0003] In the prior art, the production of welding rods is basically completed through production lines, but the welding rod weighing and packaging process is generally still completed manually, requiring workers to call out a certain number of welding rods, then place the welding rods on weighing equipment for weighing, and then replenish the materials according to the weighing results, and finally organize the welding rods for packaging.

[0004] With regard to the above-mentioned related technologies, the inventor found that the weighing and sorting process of welding rods is particularly troublesome and inefficient, and it is difficult to ensure work efficiency. Summary of the invention

[0005] In order to reduce labor and improve work efficiency, the present application provides an automatic weighing and stepping packaging production line for welding rods.

[0006] The present application provides a welding rod automatic weighing and stepping packaging production line, which adopts the following technical solutions:

[0007] The invention discloses an automatic weighing and stepping packaging production line for welding rods, comprising a base frame, one end of which is provided with a conveyor belt having the same length direction as the base frame, weighing devices are provided on both sides of the base frame corresponding to the discharge end of the conveyor belt, weighing plates are horizontally provided on the upper sides of the weighing devices, diverter frames capable of reciprocating along the width direction of the base frame are provided on the upper sides of the two weighing devices corresponding to the base frame, diverter arms capable of vertical movement are provided on the diverter frames, hook claws capable of hooking or releasing welding rods are provided on the lower sides of the diverter arms, and feeding components capable of feeding materials on the weighing plates are provided at the positions of the weighing devices on both sides of the base frame corresponding to the conveyor belt.

[0008] By adopting the above technical scheme, during operation, the welding rod is placed on the upper side of the conveying direction perpendicular to the conveying direction of the conveyor belt, and at the same time, a diverter rack drives the diverter arm to move to the position of the conveyor belt. After the diverter arm drives the hook to descend and hook a suitable number of welding rods, the diverter arm drives the hook to hook the welding rod up, and then the diverter rack drives the diverter arm to move to the upper side of the weighing plate, and the welding rod is placed on the upper side of the weighing plate for weighing through the hook. When the weight of the weighed welding rod is low, the feeding assembly on the same side can be used for feeding. After the weighing is completed, the welding rod can be directly taken away from the weighing plate and wait for weighing on the lower side. When the previous diverter rack drives the diverter arm to slide and hook the welding rod through the hook to send it to the weighing device on the corresponding side, the other diverter rack will also drive the other diverter arm to slide and hook the welding rod through the other hook to send it to the weighing device on the corresponding side for weighing. This cycle is repeated in sequence to achieve continuous automatic weighing of the welding rod.

[0009] Optionally, the feeding assembly includes a feeding rack whose length direction is the same as the length direction of the conveyor belt, and the end of the feeding rack close to the weighing device is tilted downward. The lower end of the feeding rack is rotatably connected to a feeding wheel whose axial direction is the same as the width direction of the base frame, and the circumferential surface of the feeding wheel is provided with a feeding groove which can drive the welding rod in the feeding rack to rotate with the feeding wheel and be delivered to the upper side of the weighing plate.

[0010] By adopting the above technical solution, under normal circumstances, the welding rods will automatically fall to the lower side of the feeding rack due to their own weight and accumulate. When feeding is needed, the welding rods at the lower end of the feeding rack can be lifted out of the feeding rack by rotating the feeding wheel and sent to the upper side of the weighing device as the feeding wheel rotates, thereby realizing feeding of the welding rods.

[0011] Optionally, a feeding slide capable of reciprocating along the width direction of the base frame is arranged on the upper side of the base frame corresponding to the conveyor belt, and a feeding vertical arm capable of reciprocating along the vertical direction is arranged on the feeding slide. A feeding cross arm is horizontally fixed to the side of the feeding vertical arm away from the feeding frame, and a feeding clamp capable of reciprocating along its length direction is arranged on the lower side of the feeding cross arm.

[0012] By adopting the above technical scheme, when it is necessary to refill the two feeding racks, the feeding vertical arm is driven by the feeding slide to slide to the upper side of the conveyor belt, and then the feeding vertical arm is driven to slide in the vertical direction, and the feeding clamping claw drives the feeding cross arm to slide along the length direction of the feeding cross arm, and the position of the feeding clamping claw is adjusted to clamp the welding rod on the upper side of the conveyor belt, and then the rear feeding vertical arm rises in the vertical direction, and at the same time the feeding slide drives the feeding vertical arm to slide to a feeding rack The upper side of the material feeding rack, and then, the material feeding vertical arm slides in the vertical direction to make the welding rod in the material feeding clamp fall to the upper side of a material feeding rack, and the welding rod is sent away by the material feeding clamp to realize the filling of the welding rod. After the placement of the welding rod in one material feeding rack is completed, the material feeding slide drives the material feeding vertical arm to return to the conveyor belt and repeats the above steps again. The welding rod is clamped by the material feeding clamp and sent to another material feeding rack, so as to realize the continuous filling of the welding rods in the two material feeding racks, thereby ensuring the filling of the welding rods in the material feeding racks.

[0013] Optionally, both sides of the feeding rack are fixedly provided with a material baffle plate which is in the same length direction as the feeding rack, a photoelectric switch is fixedly connected to the middle part of the length direction of the material baffle plate, the base frame is provided with a feeding push cylinder 1 which is in the same width direction as the base frame and can push the feeding slide to and fro, the feeding slide is vertically provided with a feeding push cylinder 2 which can push the feeding vertical arm to move vertically, the feeding cross arm is provided with a feeding push cylinder 3 which can push the feeding clamp to move along its length direction, the feeding push cylinder 1, the feeding push cylinder 2, the feeding push cylinder 3 and the feeding clamp are commonly connected with a power supply module, and the power supply module can be cut off when any of the photoelectric switches detects a welding rod.

[0014] By adopting the above technical scheme, during operation, as the welding rods in the two feeding racks gradually increase, the welding rods will gradually pile up along the inclined feeding racks. At the same time, the two baffle plates will also limit the two ends of the welding rods. When the welding rods in any feeding rack increase to the point that the photoelectric switch in the middle of the baffle plate can detect the welding rods, the photoelectric switch can control the power supply module to cut off the power, so that the feeding push cylinder 1, the feeding push cylinder 2, the feeding push cylinder 3 and the feeding clamp will lose power and stop moving, thereby avoiding too many welding rods in the feeding rack and stopping the feeding in time.

[0015] Optionally, a lifting cylinder is vertically fixed to the lower side of the base frame corresponding to the weighing device, the telescopic rod of the lifting cylinder is arranged upward and fixed to a lifting arm in the same width direction as the base frame, and the lifting arms are fixed to lifting frames on both sides of the weighing plate corresponding to the lifting arms, and receiving grooves are arranged on the upper sides of the two lifting frames, and the distance between the two lifting frames is less than the length of the welding rod.

[0016] By adopting the above technical scheme, under normal conditions, the telescopic rod of the lifting cylinder will drive the lifting arm to rise, thereby driving the two lifting frames to rise to the upper side of the lifting slot and above the weighing plate. At this time, when the welding rod clamped by the diverter clamp falls to the upper side of the weighing plate, it will first fall into the receiving slots of the two lifting frames to avoid the welding rod falling directly to the weighing plate, reduce the impact of the welding rod on the weighing plate, and organize the welding rod through the receiving slot to avoid the welding rod from scattering. Then, as the lifting cylinder descends, the welding rod will fall onto the weighing plate and be weighed by the scale to ensure the accurate weighing of the welding rod.

[0017] Optionally, two temporary storage racks arranged along the width direction of the base frame are provided in the middle part in the length direction of the base frame, and temporary storage clamps are provided on the sides of the two temporary storage racks that are away from each other. Reversing slides that can reciprocate along the length direction of the base frame are provided on both sides of the base frame, and the sides of the two reversing slides that are close to each other are rotatably connected with vertically arranged reversing arms, and the lower ends of the two reversing arms are provided with reversing clamps that can clamp the welding rods on the weighing plate and send them to the temporary storage clamps.

[0018] By adopting the above technical scheme, during operation, after the welding rod on the weighing plate is weighed, the reversing slide on the same side tends to slide in the direction of the weighing plate, and at the same time, it can drive the reversing arm to rotate, so that the reversing clamping claw rotates in the direction of the corresponding weighing plate, and clamps the welding rod on the upper side of the weighing plate through the reversing clamping claw, and then the reversing slide moves in the opposite direction, and at the same time, the rotating arm drives the reversing clamping claw to rotate until the reversing slide slides to the position of the temporary storage rack, and at the same time, the temporary storage clamping claw of the corresponding temporary storage rack will also be opened, so that the welding rod in the reversing clamping claw is inserted into the temporary storage clamping claw, and then, the temporary storage clamping claw clamps the welding rod, and the reversing slide drives the reversing clamping claw to withdraw, so that the welding rod can be taken out from the weighing plate, which is convenient for the subsequent weighing of the welding rod, and realizes the reversal of the welding rod, so as to facilitate the removal of the welding rod after weighing.

[0019] Optionally, a discharging rack in the same length direction as the base frame is provided at one end of the base frame away from the conveyor belt; discharging slides capable of moving along the length direction of the base frame are provided on both sides of the base frame, and discharging slides capable of moving toward or away from each other are vertically provided on one side where the two discharging slides are close to each other, and discharging vertical arms capable of moving along the vertical direction are provided on the discharging slides, and discharging clamps capable of clamping welding rods in the temporary storage clamps and delivering them to the discharging rack are provided at the lower ends of the discharging vertical arms.

[0020] The discharging mechanism that the discharging jaws are in the middle of being moved is like this: after the welding rod is delivered to the temporary storage clamping jaw, any discharging slide will slide to the position of the temporary storage rack, and drive the discharging vertical arm to move toward the temporary storage clamping jaw through the discharging slide. At the same time, the discharging vertical arm vertically moves to adjust the discharging clamping jaw so that the discharging clamping jaw clamps the welding rod in the temporary storage clamping jaw. Then, the temporary storage clamping jaw is released, and the discharging slide drives the discharging vertical arm to slide out of the position of the temporary storage rack and deliver it to the position of the discharging rack. Then, the discharging slide drives the discharging vertical arm to slide, and the discharging vertical arm drives the discharging clamping jaw to slide, adjusts the position of the discharging clamping jaw, so that the welding rod in the discharging clamping jaw is delivered to the discharging rack, and then the discharging slide is reset to realize the discharging of the welding rod. After the discharging of the welding rod in the discharging rack is completed, the other discharging slide will repeat the above-mentioned replenishment to take out the welding rod in the temporary storage clamping jaw on its corresponding side and deliver it to the discharging rack to wait for discharging. This cycle is repeated in sequence to realize the continuous discharging of the welding rod.

[0021] Optionally, a push plate capable of sliding back and forth along the discharging rack is provided in the discharging rack, and a push cylinder capable of pushing the push plate to slide back and forth is fixedly connected to one side of the discharging rack.

[0022] By adopting the above technical solution, when the welding rod falls into the discharge rack, the pushing cylinder drives the telescopic rod to slide, so that the welding rod can be pushed out from the pushing plate, thereby realizing the discharge of the welding rod.

[0023] Optionally, a packaging box with an open upper side is placed in the discharge rack.

[0024] By adopting the above technical solution and placing a packaging box in the discharge rack, the welding rods clamped by the discharge clamps can be directly dropped into the packaging box, thereby directly realizing the boxing and discharge of the welding rods.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. During operation, the welding rod is placed on the upper side of the conveyor belt along the conveying direction perpendicular to the conveyor belt. At the same time, a diverter rack drives the diverter arm to move to the position of the conveyor belt. After the diverter arm drives the hook to descend and hook a suitable number of welding rods, the diverter arm drives the hook to hook the welding rod up. Then, the diverter rack drives the diverter arm to move to the upper side of the weighing plate, and the welding rod is placed on the upper side of the weighing plate through the hook for weighing. When the weight of the weighed welding rod is low, the feeding assembly on the same side can be used for feeding. After the weighing is completed, the welding rod can be directly taken away from the weighing plate and wait for weighing on the lower side. When the previous diverter rack drives the diverter arm to slide through the hook to hook the welding rod and send it to the weighing device on the corresponding side, the other diverter rack will also drive the other diverter arm to slide through the other hook to hook the welding rod and send it to the weighing device on the corresponding side for weighing. This cycle is repeated in sequence to achieve continuous automatic weighing of the welding rod.

[0027] 2. When it is necessary to refill the two feeding racks, the feeding vertical arm is driven by the feeding slide to slide to the upper side of the conveyor belt, and then the feeding vertical arm is driven to slide in the vertical direction, and the feeding clamp is driven to slide along the length direction of the feeding horizontal arm by the feeding clamp. The position of the feeding clamp is adjusted, and the welding rod on the upper side of the conveyor belt can be clamped by the feeding clamp. Then the rear feeding vertical arm rises in the vertical direction, and at the same time, the feeding slide drives the feeding vertical arm to slide to the upper side of one feeding rack. Then, the feeding arm slides in the vertical direction to make the welding rod in the feeding clamp fall to the upper side of one feeding rack, and the welding rod is sent out by the feeding clamp to realize the feeding of the welding rod. After the placement of the welding rod in one feeding rack is completed, the feeding slide drives the feeding arm back to the conveyor belt and repeats the above steps again, and the welding rod is clamped by the feeding clamp and sent to another feeding rack, so that the welding rods in the two feeding racks can be continuously fed in sequence, ensuring the filling of the welding rods in the feeding racks.

[0028] 3. During operation, after the welding rod on the weighing plate is weighed, the reversing slide on the same side tends to slide in the direction of the weighing plate, and at the same time, it can drive the reversing arm to rotate, so that the reversing clamp rotates in the direction of the corresponding weighing plate, and clamps the welding rod on the upper side of the weighing plate through the reversing clamp, and then the reversing slide moves in the opposite direction, and at the same time, the rotating arm drives the reversing clamp to rotate until the reversing slide slides to the position of the temporary storage rack, and at the same time, the temporary storage clamp of the corresponding temporary storage rack will also be opened, so that the welding rod in the reversing clamp is inserted into the temporary storage clamp, and then, the temporary storage clamp clamps the welding rod, and the reversing slide drives the reversing clamp to withdraw, so that the welding rod can be taken out from the weighing plate, which is convenient for the subsequent weighing of the welding rod, and realizes the reversal of the welding rod, so as to complete the removal of the welding rod after weighing.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The embodiment of the present application discloses an automatic weighing and stepping packaging production line for welding rods.

[0040] Example 1: Reference Figure 1 and Figure 2A welding rod automatic weighing step-by-step packaging production line includes a base frame 1, a feeding assembly 2 is arranged at one end of the base frame 1, and the feeding assembly 2 includes two parallel conveyor belts 21, the length direction of the two conveyor belts 21 is the same as the length direction of the base frame 1, the distance between the two vertical conveyor belts is less than the length of the welding rod, and the two conveyor belts 21 are provided with a servo motor 22 for driving the conveyor belts 21 to move synchronously. When working, the welding rod is placed on the upper side of the two conveyor belts 21, and the length direction of the welding rod is ensured to be perpendicular to the length direction of the two conveyor belts 21, so that the welding rod can be transported by the continuous rotation of the two conveyor belts 21.

[0041] Reference Figure 1 and Figure 2 , the base frame 1 is fixedly connected with support frames 11 on both sides of the corresponding feeding assembly 2, and the two support frames 11 are provided with feeding assemblies 3 on the sides close to each other, and the feeding assemblies 3 include feeding frames 31 respectively fixed to the support frames 11, and the length direction of the two feeding frames 31 is the same as the length direction of the base frame 1, and the two feeding frames 31 are arranged at an angle downward at one end close to the conveyor belt 21 for discharging materials. The two sides of the feeding frame 31 are vertically fixedly connected with blocking plates 32 along the length direction thereof, and the lower ends of the feeding frames 31 are rotatably connected with feeding wheels 33 whose axis direction is perpendicular to the length direction of the feeding frames 31, and the middle part of the peripheral surface of the feeding wheel 33 close to the feeding frame 31 can abut against the lower end of the feeding frame 31. A plurality of feeding grooves 331 are evenly arranged on the circumference of the feeding wheel 33 with its axis as the center. The length directions of the plurality of feeding grooves 331 are all the same as the axis direction of the feeding wheel 33. A servo motor 332 capable of driving the feeding wheel 33 to rotate is fixedly connected to one end of the feeding rack 31 corresponding to each feeding wheel 33.

[0042] When in use, the welding rod is placed in the feeding rack 31 along the length direction perpendicular to the feeding rack 31, and the welding rod can be limited by the baffle plates 32 on both sides of the feeding rack 31. By setting the feeding rack 31 tilted, the welding rods in the feeding rack 31 can abut against the circumference of the feeding wheel 33 by their own weight. When feeding is needed, the servo motor 2 332 drives the feeding wheel 33 to rotate. As the feeding wheel 33 rotates, the welding rod that falls into the feeding groove 331 on the circumference of the feeding wheel 33 will be lifted from the feeding rack 31 as the feeding wheel 33 rotates, and sent to the side of the feeding wheel 33 away from the feeding rack 31 as the feeding wheel 33 rotates.

[0043] Reference Figure 1 and Figure 3, a horizontally arranged receiving frame 12 is fixedly connected to the upper side of the two supporting frames 11, and the length direction of the receiving frame 12 is perpendicular to the length direction of the bottom frame 1, and a feeding slide 4 is vertically arranged at the higher end of the receiving frame 12 close to the feeding frame 31, and the feeding slide 4 is connected to the receiving frame 12 by sliding along the length direction of the receiving frame 12, and a feeding push cylinder 140 is fixedly connected to the side of the receiving frame 12 close to the feeding slide 4, and the length direction of the feeding push cylinder 140 is the same as the length direction of the receiving frame 12, and the telescopic rod of the feeding push cylinder 140 is fixedly connected to the feeding slide 4. When working, the feeding push cylinder 140 drives the telescopic rod to extend and retract, which can drive the feeding slide 4 to slide back and forth along the length direction of the receiving frame 12.

[0044] Reference Figure 1 and Figure 3 The feeding slide 4 is vertically slidably connected with a feeding vertical arm 41, and a feeding push cylinder 2 42 is vertically fixedly connected to one side of the feeding vertical arm 41 corresponding to the feeding vertical arm 41 on the feeding slide 4, and the telescopic rod of the feeding push cylinder 2 42 is fixedly connected to one side of the feeding vertical arm 41, and a horizontally arranged feeding cross arm 43 is fixedly connected to the side of the feeding vertical arm 41 away from the feeding slide 4. The length direction of the feeding cross arm 43 is the same as the length direction of the movable frame, and the lower side of the feeding cross arm 43 is slidingly connected with a feeding clamp 44 with an opening facing downward along its length direction, and one end of the lower side of the feeding cross arm 43 is fixedly connected with a feeding push cylinder 3 45 with the same length direction as the feeding cross arm 43. The feeding clamp 44 can adopt an electric mechanical clamp, and one end of the feeding push cylinder 3 45 is fixedly connected to the feeding clamp 44, and the feeding clamp 44 can clamp the welding rod on the conveyor belt 21 and send it back and forth to the upper side of the two feeding racks 31 in sequence.

[0045] During operation, the material feeding push cylinder 1 40 will drive the material feeding slide 4 to move to the upper side of the position between the two conveyor belts 21. At the same time, the material feeding push cylinder 2 42 will drive the material feeding vertical arm 41 to move downward in the vertical direction. Then, the material feeding push cylinder 3 45 will drive the material feeding clamping claw 44 to slide and adjust the position, so that the material feeding clamping claw 44 extends to between the two conveyor belts 21 and clamps the welding rods transported on the two conveyor belts 21. Then, the material feeding push cylinder 2 42 will drive the material feeding vertical arm 41 to move in the vertical direction, lift the material feeding clamping claw 44, and then drive the material feeding slide 4 to slide through the material feeding push cylinder 1 40 to adjust the position of the material feeding vertical arm 41. The feeding clamp 44 is moved to the upper side of a feeding rack 31, and the feeding push cylinder 42 is used to drive the feeding vertical arm 41 to move, so that the welding rod clamped by the feeding clamp 44 falls onto the feeding rack 31, and the feeding clamp 44 can release the welding rod, completing the replenishment of the welding rod on one side of the feeding rack 31, and then, the feeding vertical arm 41 and the feeding cross arm 43 are reset to drive the feeding clamp 44 to clamp the welding rod on the upper side of the conveyor belt 21 again, and send it to the upper side of the other feeding rack 31 again, so as to complete the replenishment of the welding rod on the other feeding rack 31, and this reciprocating cycle can be used to realize the replenishment of the welding rods on the two feeding racks 31.

[0046] Reference Figure 2A photoelectric switch 321 is fixedly connected to the upper middle part of the length direction of the baffle plate 32 on one side of each feeding rack 31, and a power supply module is commonly connected to the feeding push cylinder 1 40, the feeding push cylinder 2 42, the feeding push cylinder 3 45 and the feeding clamp 44. When any photoelectric switch 321 detects a welding rod, the photoelectric switch 321 can control the power supply module to cut off the power, thereby cutting off the power of the feeding push cylinder 1 40, the feeding push cylinder 2 42, the feeding push cylinder 3 45 and the feeding clamp 44. In this way, when working, it is possible to avoid too many welding rods in the feeding rack 31 and stop feeding in time.

[0047] Reference Figure 2 and Figure 4 A weighing assembly 5 is provided on the side of the base frame 1 corresponding to the two feeding wheels 33 away from the feeding frame 31. The weighing assembly 5 includes weighing devices 51 respectively fixed to the side of the two feeding wheels 33 away from the feeding frame 31, and a horizontally arranged weighing plate 511 is fixed to the upper side of the weighing device 51. The weighing assembly 5 also includes lifting cylinders 52 respectively fixed vertically to the base frame 1 and located at the lower side of the weighing device 51. The telescopic rod of the lifting cylinder 52 is arranged upward and fixed with a lifting arm 53. The length direction of the lifting arm 53 is the same as the width direction of the base frame 1. The lifting arms 53 are vertically fixed with lifting frames 54 on both sides of the weighing plates 511. The distance between the lifting frames 54 on both sides of each weighing plate 511 is less than the length of the welding rod, and the upper side of the lifting frames 54 is provided with an inverted trapezoidal receiving groove.

[0048] Reference Figure 4 and Figure 5 , the side of the receiving frame 12 away from the feeding slide 4 is slidably connected with two diverter frames 6 along the length direction of the receiving frame 12, and the two ends of the receiving frame 12 are fixed with a diverter push cylinder 1 61 with the same axial direction as the length direction of the receiving frame 12, and the telescopic rods of the two diverter push cylinders 1 61 are respectively fixed to the two diverter frames 6, and the two diverter frames 6 are vertically slidably connected with a diverter arm 62 on the side away from the receiving frame 12, and the diverter push cylinder 2 63 is vertically fixed on the side of the diverter frame 6 corresponding to the diverter arm 62, and the telescopic rod of the diverter push cylinder 2 63 is fixed to one side of the diverter arm 62. The lower side of the diverter arm 62 is rotatably connected with a rotating shaft 64 with the same axial direction as the width direction of the base frame 1, and the length of the rotating shaft 64 is less than the width between the two conveyor belts 21. Both ends of the rotating shaft 64 are fixedly connected with vertically arranged hook claws 641, and the openings of the hook claws 641 face the receiving frame 12. The middle part of the rotating shaft 64 is connected with a gear 642. A reciprocating cylinder 65 is vertically fixedly connected to the diverter arm 62. The telescopic rod of the reciprocating cylinder 65 is fixedly connected to a vertically arranged rack 651 that meshes with the gear 642.

[0049] During operation, a diverter push cylinder 1 61 drives a diverter rack 6 to slide to a position between the two conveyor belts 21, and then the diverter push cylinder 2 63 drives the diverter arm 62 to descend, so that the two hook claws 641 at the lower end of the diverter arm 62 fall between the two conveyor belts 21, and then, with the conveyance of the conveyor belt 21, the welding rod can be conveyed to the position of the hook claw 641, so that the welding rod falls into the hook claw 641, and when the welding rod in the hook claw 641 is collected, the corresponding diverter push cylinder 2 63 drives the diverter arm 62 to rise, thereby driving the welding rod to rise through the hook claw 641, and then, the corresponding diverter push cylinder 1 61 drives the diverter arm 62 to move to the upper side of the weighing device 51 on the corresponding side, so that the two hook claws 641 are respectively located on the weighing plate 5 11 and the lifting frame 54, then, the splitter arm 62 is driven to move in the vertical direction through the splitter push cylinder 2 63, so that the hook 641 falls, so that the welding rod falls completely into the receiving grooves of the two lifting frames 54, then, the reciprocating cylinder 65 drives the rack 651 to move vertically, thereby driving the gear 642 to rotate, driving the rotating shaft 64 to rotate, and can drive the two hooks 641 to rotate in the direction away from the receiving frame 12, so that the welding rod is separated from the hook 641, then, the lifting cylinder 52 drives the telescopic rod to retract, and the two lifting frames 54 can be driven downward by the lifting arm 53, thereby driving the welding rod to fall until it falls completely on the weighing plate 511, and the welding rod can be weighed by the weighing plate 511;

[0050] When the number of weighing welding rods is small, the feeding wheel 33 rotates to replenish the welding rods to the weighing plate 511, and then the diverter arm 62 and the hook 641 are reset to wait for the lower side to grab the welding rods. At the same time, when one hook 641 hooks the welding rod and moves toward the weighing device 51 on one side, the other hook 641 will also move toward the two conveyor belts 21, repeating the action of the previous hook 641, hooking the welding rod and returning to the upper side of the weighing device 51 on the corresponding side, and also realizing the weighing of the welding rods, so as to realize the sequential and continuous weighing of the welding rods.

[0051] Reference Figure 1 and Figure 6A reversing assembly 7 is provided on the side of the base frame 1 corresponding to the weighing assembly 5 away from the feeding assembly 2. The reversing assembly 7 includes two temporary storage racks 71 fixedly connected to the middle part of the base frame 1.

[0052] When the welding rod on the weighing device 51 is weighed, the reversing push cylinder 74 on the corresponding side drives the telescopic rod to extend and retract, driving the reversing slide 73 to move toward the weighing device 51. At the same time, the reciprocating motor 76 drives the reversing arm 75 to rotate toward the weighing device 51, so that the reversing clamp 77 completes the clamping of the welding rod on the corresponding weighing device 51. Then, the reversing push cylinder 74 drives the telescopic rod to extend and retract, thereby driving the reversing slide 73 to move away from the weighing device 51. At the same time, the reciprocating motor 76 drives the rotating arm to rotate. Reset, when the reversing slide 73 moves to the position of the temporary storage rack 71, it stops moving, and the reversing clamp 77 will also rotate toward the temporary storage clamp 72 on the corresponding side with the rotation of the reversing arm 75. At the same time, the temporary storage clamp 72 opens, so that the welding rod in the reversing clamp 77 can be inserted into the temporary storage clamp 72, and then, the temporary storage clamp 72 closes to clamp the welding rod, and the reversing clamp 77 opens and withdraws, so that the reversal of the welding rod can be realized, so that the welding rod whose length direction is perpendicular to the base frame 1 is rotated until the length direction is the same as the length direction of the base frame 1.

[0053] Reference Figure 6A discharging assembly 8 is arranged on the side of the base frame 1 corresponding to the reversing assembly 7 away from the weighing assembly. The discharging assembly 8 includes discharging slides 81 respectively connected to the two sides of the base frame 1 in a sliding manner along the length direction of the base frame 1.

[0054] Reference Figure 6 A discharge rack 86 is vertically fixedly connected to the middle part of one end of the base frame 1 away from the conveyor belt 21, and the length direction of the discharge rack 86 is the same as the length direction of the base frame 1. Limiting plates 87 with the same length direction as the discharge rack 86 are vertically fixedly connected to both sides of the discharge rack 86. A push plate 88 is vertically arranged inside the discharge rack 86, and the limiting plate 87 is extended from one side of the push plate 88. A pushing cylinder 89 is also fixedly connected to the discharge rack 86, and the length direction of the pushing cylinder 89 is the same as the length direction of the discharge rack 86. The telescopic rod of the pushing cylinder 89 is fixedly connected to one side of the push plate 88 extending from the limiting plate 87.

[0055] During operation, the telescopic rod of the first discharging push cylinder 82 is telescopically extended to drive the discharging slide 81 to move along the base frame 1 toward the temporary storage rack 71. At the same time, the second discharging push cylinder 831 and the third discharging push cylinder 841 drive the discharging slide 83 and the discharging vertical arm 84 to slide, and adjust the position of the discharging clamp 85. When the discharging slide 81 drives the discharging clamp 85 to move to the position of the transfer rack, the welding rod on the temporary storage clamp 72 is clamped by the discharging clamp 85. Then, the temporary storage clamp 72 releases the clamp, and the welding rod is driven to withdraw from the temporary storage clamp 72 by the discharging clamp 85. Then, the discharging push cylinder 82 drives the discharging slide 81 to move in the direction of the discharging rack 86, and drives the discharging slide 83 to slide along the cross beam 811 through the second discharging push cylinder 831, and drives the discharging vertical arm 84 to slide in the vertical direction The packing machine 81 is packed with the packaging machine 82, and the packing machine 82 is packed with the packaging machine 82, and the packing machine 82 is packed with the packaging machine 82.

[0056] In addition, the welding rod packaging box with an open upper side can be directly placed on the upper side of the discharge rack, so that the welding rods that fall into the discharge rack can be directly dropped into the packaging box.

[0057] The implementation principle of the welding rod automatic weighing and stepping packaging production line in the embodiment of the present application is:

[0058] During operation, the welding rod is placed on the upper side of the two conveyor belts 21, and the length direction of the welding rod is ensured to be perpendicular to the length direction of the two conveyor belts 21, so that the welding rod can be transported by the continuous rotation of the two conveyor belts 21;

[0059] A diverter push cylinder 1 61 drives a diverter rack 6 to slide to the position between the two conveyor belts 21, and then the diverter push cylinder 2 63 drives the diverter arm 62 to descend, so that the two hook claws 641 at the lower end of the diverter arm 62 fall between the two conveyor belts 21, and then, with the conveyor belt 21, the welding rod can be transported to the position of the hook claw 641, so that the welding rod falls into the hook claw 641, and when the welding rod in the hook claw 641 is collected, the corresponding diverter push cylinder 2 63 drives the diverter arm 62 to rise, thereby driving the welding rod to rise through the hook claw 641, and then, the corresponding diverter push cylinder 1 61 drives the diverter arm 62 to move to the upper side of the weighing device 51 on the corresponding side, so that the two hook claws 641 are respectively located on the weighing plate 51 1 and the lifting frame 54, then, the splitter arm 62 is driven to move in the vertical direction through the splitter push cylinder 2 63, so that the hook 641 falls, so that the welding rod falls completely into the receiving grooves of the two lifting frames 54, then, the reciprocating cylinder 65 drives the rack 651 to move vertically, thereby driving the gear 642 to rotate, driving the rotating shaft 64 to rotate, and can drive the two hooks 641 to rotate in the direction away from the receiving frame 12, so that the welding rod is separated from the hook 641, then, the lifting cylinder 52 drives the telescopic rod to retract, and the two lifting frames 54 can be driven downward by the lifting arm 53, thereby driving the welding rod to fall until it falls completely on the weighing plate 511, and the welding rod can be weighed by the weighing plate 511;

[0060] When the number of weighing welding rods is small, the feeding wheel 33 is rotated to replenish the welding rods to the weighing plate 511, and then the diverter arm 62 and the hook 641 are reset to wait for the lower side to grab the welding rods. At the same time, when one hook 641 hooks the welding rod and moves toward the weighing device 51 on one side, the other hook 641 will also move toward the two conveyor belts 21, repeating the action of the previous hook 641, hooking the welding rod and returning to the upper side of the weighing device 51 on the corresponding side, and also realizing the weighing of the welding rod, so as to realize the sequential and continuous weighing of the welding rods;

[0061] When the welding rod on the weighing device 51 is weighed, the reversing push cylinder 74 on the corresponding side drives the telescopic rod to extend and retract, driving the reversing slide 73 to move toward the weighing device 51. At the same time, the reciprocating motor 76 drives the reversing arm 75 to rotate toward the weighing device 51, so that the reversing clamp 77 completes the clamping of the welding rod on the corresponding weighing device 51. Then, the reversing push cylinder 74 drives the telescopic rod to extend and retract, thereby driving the reversing slide 73 to move away from the weighing device 51. At the same time, the reciprocating motor 76 drives the rotating arm to rotate. Reset, when the reversing slide 73 moves to the position of the temporary storage rack 71 and stops moving, the reversing clamp 77 will also move toward the temporary storage clamp 72 on the corresponding side along with the rotation of the reversing arm 75. At the same time, the temporary storage clamp 72 opens, so that the welding rod in the reversing clamp 77 can be inserted into the temporary storage clamp 72. Then, the temporary storage clamp 72 closes to clamp the welding rod, and the reversing clamp 77 opens and withdraws, so that the welding rod can be reversed, so that the welding rod whose length direction is perpendicular to the base frame 1 is rotated until the length direction is the same as the length direction of the base frame 1;

[0062] The telescopic rod of the first discharge push cylinder 82 is extended to drive the discharge slide 81 to move along the bottom frame 1 toward the temporary storage rack 71. At the same time, the second discharge push cylinder 831 and the third discharge push cylinder 841 drive the discharge slide 83 and the discharge vertical arm 84 to slide, and adjust the position of the discharge clamp 85. When the discharge slide 81 drives the discharge clamp 85 to move to the position of the transfer rack, the discharge clamp 85 clamps the welding rod on the temporary storage clamp 72, and then the temporary storage clamp 72 releases the clamp, and the discharge clamp 85 drives the welding rod to exit the temporary storage clamp 72, and then , the discharging push cylinder 1 82 drives the discharging slide 81 to move toward the discharging rack 86, and drives the discharging slide 83 to slide along the crossbeam 811 through the discharging push cylinder 2 831, and drives the discharging vertical arm 84 to slide along the vertical direction until the discharging clamp 85 is located on the upper side of the discharging rack 86, and then the discharging clamp 85 releases the clamp to make the welding rod fall on the upper side of the discharging rack 86, and finally, the pushing cylinder 89 drives the pushing plate to slide along the discharging rack 86, so that the fully sorted welding rod can be pushed out and directly sent to the packaging machine for box packaging;

[0063] After one discharging push cylinder 82 drives a slide to clamp the welding rod, the other discharging push cylinder 82 will also drive the other discharging slide 81 to clamp the welding rod through the discharging clamping claw 85. After the push plate 88 pushes out and resets the welding rod clamped by the previous discharging clamping claw 85, the other discharging clamping claw 85 will also send the welding rod to the discharging rack 86, waiting for the push plate 88 to push out and the other discharging push cylinder 82 to reset again. In this way, the two discharging clamping claws 85 can continuously clamp the corresponding side welding rods and send them to the discharging rack 86 for discharging in turn.

[0064] Example 2: Reference Figure 7 and Figure 8 , a welding rod automatic weighing stepping packaging production line, which is different from the embodiment in that:

[0065] The push plate 88 includes a movable plate 881 located on the upper side of the limit plate 87 and a push plate 882 hinged on the lower side of the movable plate 881 and extending between the two limit plates 87. The rotation axis 64 line of the push plate 882 is the same as the width direction of the discharge rack 86, and the movable plate 881 corresponds to the end of the push plate 882 close to the temporary storage rack 71 and is fixed with a vertical baffle 883. The vertical baffle 883 can limit the push plate 882 to swing only in the direction away from the temporary storage rack 71, and the telescopic rod of the push cylinder 89 is fixed to one end of the movable plate 881.

[0066] The unloading rack 86 is fixedly connected to one end thereof near the temporary storage rack 71 with an unloading platform 9 in the same plane as the upper side of the unloading rack 86. A conveyor belt 91 is arranged on the upper side of the unloading platform 9, and the conveyor belt 91 has a conveying direction perpendicular to the length direction of the unloading rack 86. A positioning plate 92 is fixedly connected to one end of the conveyor belt 91. Packaging boxes with upper openings can be arranged and placed on the conveyor belt 91. The length direction of the packaging boxes is the same as the length direction of the unloading rack 86. A push cylinder 93 is fixedly connected to the side of the unloading platform 9 corresponding to the conveyor belt 21 away from the unloading rack 86. The length direction of the push cylinder 93 is the same as the length direction of the unloading rack 86, and the telescopic rod of the push cylinder 93 faces the conveyor belt 91 and is fixedly connected to a push plate 94.

[0067] Compared with the first embodiment, the advantages are as follows: during operation, after placing the packaging boxes on the conveyor belt 91 in turn, the conveyor belt 91 can convey the packaging boxes to the rear side of the unloading rack 86, and then, the pushing cylinder 93 drives the telescopic rod to extend, so that the packaging boxes on the upper side of the conveyor belt 91 can be pushed onto the unloading rack 86, and because the pushing plate 882 can rotate in a direction away from the temporary storage rack 71, the packaging boxes can push the pushing plate 882 to swing, so that the packaging boxes are placed in the unloading rack 86, and the bag packaging boxes are completely placed After being placed in the discharge rack 86, the pushing plate 94 will be reset and the swing plate will also swing back to the vertical state. Then, the welding rod clamped by the discharge clamp 85 will also fall directly into the packaging box in the discharge rack 86 to realize the boxing of the welding rod. Then, the pushing cylinder 89 drives the movable plate 881 to push. Due to the action of the vertical baffle 883, the pushing plate 882 will also move synchronously with the movable plate 881, thereby pushing the boxed welding rod directly out of the discharge rack 86. This reciprocating cycle can realize the continuous boxing and discharging of the welding rod.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
