Description

Technical Field

[0001] This utility model relates to the field of welding electrode packaging technology, and in particular to a packaging machine for welding electrodes. Background Technology

[0002] Currently, in the welding electrode manufacturing industry, finished welding electrodes are typically packaged using packaging machines. This improves the efficiency of welding electrode packaging.

[0003] In the aforementioned welding rod packaging process, a suction head assembly is typically used to pick up the cardboard before placing it on a packaging rack. However, because the cardboard is stacked, there are frictional and electrostatic forces between them. These forces create an attraction between the cardboard pieces, potentially causing adjacent pieces to be pulled out when the cardboard separates. When multiple pieces of cardboard fall onto the packaging rack, it can cause the packaging process to stall or come to a standstill. Utility Model Content

[0004] The purpose of this invention is to provide a packaging machine for welding rods, which solves the problem of how to avoid jamming in the packaging machine for welding materials.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a packaging machine for welding electrodes, comprising:

[0007] frame;

[0008] A conveyor, which is mounted on the frame;

[0009] A contouring boss is provided on the conveyor and is used to limit the position of the cardboard for welding rod packaging.

[0010] A cardboard suction head is disposed at the inlet end of the conveyor and is used to pick up the cardboard for welding rod packaging and place it at the contoured boss.

[0011] A rangefinder is mounted on the top of the frame and is used to monitor the straight-line distance from the rangefinder to the center of the cardboard for packaging welding rods.

[0012] An alarm is mounted on the frame and is connected to the rangefinder via a signal connection.

[0013] Furthermore, a drive component is connected to the conveying component.

[0014] Furthermore, the conveying component includes at least two parallel conveying chains, each of which is provided with the contoured boss.

[0015] Furthermore, a pressure plate is provided on the side of the conveyor chain, which is used to further limit the edge of the cardboard for welding rod packaging.

[0016] Furthermore, the contoured boss includes several sets of first bosses and second bosses arranged facing each other, and a space for accommodating the cardboard for welding rod packaging is formed between the first bosses and the second bosses.

[0017] Furthermore, the cardboard suction head includes a first cardboard suction head and a second cardboard suction head, and the first cardboard suction head and the second cardboard suction head are coaxially connected to a suction head steering component.

[0018] Furthermore, the working distance of the first cardboard suction head is shorter than that of the second cardboard suction head.

[0019] Furthermore, the frame is also provided with a cardboard placement platform, which is inclined relative to the feed end of the conveyor.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] This utility model discloses a packaging machine for welding rods, which uses a conveyor on the machine frame to transport cardboard for welding rod packaging; uses a contoured boss on the conveyor to limit and fix the cardboard for welding rod packaging; and uses a cardboard suction head to suck the cardboard for welding rod packaging to the feed end of the conveyor.

[0022] In addition, by setting up a rangefinder to monitor the distance between the rangefinder and the cardboard for welding rod packaging, when the cardboard is placed on the conveyor, if the rangefinder detects that the distance between the cardboard and the rangefinder is less than the distance between the rangefinder and one piece of cardboard for welding rod packaging, it proves that the cardboard suction head has picked up more than or equal to two pieces of cardboard. At this time, after receiving the signal, the rangefinder will transmit a signal to the alarm to remind the worker to check the packaging operation and remove the excess cardboard to avoid the welding material packaging machine from jamming.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1 The packaging machine for welding rods shown includes a frame 1, a conveyor 2, a contouring boss 3, a cardboard suction head 4, a rangefinder 5, and an alarm 6.

[0031] Specifically, see Figure 1 and Figure 2 The conveyor 2 is mounted on the frame 1 and is designed to transport the cardboard 8 to the welding rod feeding end. A drive unit (not shown in the figure) is connected to the conveyor 2. The drive unit provides the corresponding driving force to the conveyor 2 to enable continuous conveying operation.

[0032] In this embodiment of the invention, the conveying component 2 includes at least two parallel conveying chains 201, and the load of the cardboard 8 can be distributed to the two conveying chains 201, providing stable support for the cardboard 8. Furthermore, the cardboard conveying operation is not limited to using conveying chains 201; conveying chain plates or conveyor belts can also be used.

[0033] Furthermore, in this embodiment of the invention, a pressure plate 9 is also provided on the side of the conveyor chain 201, such as... Figure 3 As shown, the pressure plate 9 is used to further limit the edge of the cardboard 8, more specifically, to limit point A on the cardboard 8. When the cardboard 8 is placed on the conveyor 2, the pressure plate 9 presses the edge of the cardboard 8 to prevent the cardboard 8 from shifting when the conveyor 2 moves towards the welding rod feeding end.

[0034] In this embodiment of the invention, the aforementioned contouring boss 3 is disposed on the conveying member 2 to fix and limit the cardboard 8. Specifically, several sets of contouring bosses 3 are provided, each including a first boss 301 and a second boss 302. Each first boss 301 and second boss 302 arranged opposite to each other constitutes a set of contouring limiting members, and a limiting space for accommodating the cardboard 8 is formed between the first boss 301 and the second boss 302.

[0035] In this embodiment of the invention, a cardboard suction head 4 is provided. Specifically, the cardboard suction head 4 is disposed at the inlet end of the conveyor 2, and is designed to pick up the cardboard 8 and place it onto the contoured protrusion 3. The cardboard suction head 4 includes a first cardboard suction head 401 and a second cardboard suction head 402, which are coaxially connected to a suction head deflector. A drive source is connected to the suction head deflector to provide stable rotational force to the first cardboard suction head 401 and the second cardboard suction head 402.

[0036] Furthermore, in this embodiment of the invention, the operating sequence of the first cardboard suction head 401 and the second cardboard suction head 402 is adjusted. Specifically, the first cardboard suction head 401 is configured to contact the cardboard 8 first, followed by the second cardboard suction head 402. When the first cardboard suction head 401 contacts the cardboard 8 first, it only performs an initial suction of the cardboard 8, meaning the suction force provided by the first cardboard suction head 401 is not large, just enough to move the cardboard 8. When the second cardboard suction head 402 contacts the cardboard 8 later, the suction force provided is greater than that of the first cardboard suction head 401, aiming to pick up the cardboard 8 onto the conveyor 2, more specifically, to pick up the cardboard 8 onto the contour-guided limiting member on the conveyor 2, that is, between the opposing first protrusion 301 and the second protrusion.

[0037] In this embodiment of the invention, in order to pick up the cardboard 8 onto the conveyor 2, on the one hand, sufficient suction force must be applied to the second cardboard suction head 402; on the other hand, in this embodiment, the working distance of the first cardboard suction head 401 is set to be less than the working distance of the second cardboard suction head 402, that is, the length of the first cardboard suction head 401 is less than the length of the second cardboard suction head 402, so that the working distance of the second cardboard suction head 402 can extend to the conveyor 2. After both the first cardboard suction head 401 and the second cardboard suction head 402 have completed their suction operations, the aforementioned pressing plate 9 will press the edge of the cardboard 8 tightly.

[0038] In this example, a cardboard placement platform 7 is also provided to hold and accommodate stacked cardboard 8 for the cardboard suction head 4 to pick up. The cardboard placement platform 7 is inclined relative to the feed end of the conveyor 2, thereby reducing the working distance of the cardboard suction head 4 and speeding up the packaging rate.

[0039] Since the cardboard 8 is stacked on the cardboard placement table 7, there is friction and electrostatic force between the cardboard 8, resulting in a certain attraction between them. Therefore, when the cardboard suction head 4 is performing the suction operation, it may pick up multiple pieces of cardboard 8. When multiple pieces of cardboard 8 are picked up and placed on the conveyor 2, packaging jamming can easily occur. To address this, in this example, a rangefinder 5 is installed at the top of the frame 1 to monitor the straight-line distance from the rangefinder 5 to the center of the cardboard 8.

[0040] In specific monitoring, the cardboard 8 can be monitored when it is picked up by the cardboard suction head 4 and placed onto the conveyor 2, and simultaneously pressed by the pressure plate 9; alternatively, it can be monitored before the cardboard 8 falls onto the conveyor 2. When the aforementioned second cardboard suction head 402 is performing its suction operation, the real-time position of the cardboard 8 can be located by pausing the operation of the second cardboard suction head 402, thereby monitoring the straight-line distance from the rangefinder 5 to the center of the cardboard 8. The specific monitoring method can be adjusted according to actual needs.

[0041] When the rangefinder 5 detects that the straight-line distance is less than the predetermined straight-line distance from the rangefinder 5 to the center of a single piece of cardboard 8, it means that the cardboard suction head 4 has picked up two or more pieces of cardboard 8.

[0042] To provide timely feedback on the situation where the cardboard suction head 4 picks up multiple pieces of cardboard 8, an alarm 6 is also installed on the frame 1 in this example. The alarm 6 is connected to the rangefinder 5. When the rangefinder 5 detects that the distance between the cardboard 8 and the rangefinder 5 is less than a predetermined straight-line distance when the cardboard 8 is placed on the conveyor 2, the rangefinder 5 will send a signal to the alarm 6. The worker will then respond promptly based on the signal from the alarm 6, stop the machine to check, and avoid any delays in the packaging operation.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
