Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a pole piece scraping paper plastic line butt joint machine and a coating machine scraping waste glue device. Background Art

[0002] In lithium battery coating machines, a fishing line device is generally used to scrape away waste glue from the coating machine. The pole scraping plastic wire usually uses a rolled plastic wire (such as a fishing line). When the old roll of plastic wire is about to be used up, it needs to be connected with a new roll of plastic wire. The existing technology usually uses manual knotting to connect the old roll of plastic wire with the new roll of plastic wire. However, the diameter of the knot where the two rolls of plastic wire are connected is often larger than the wire diameter, and it is impossible to pass through the small hole where the plastic wire is fixed under the drive of the motor. Because the diameter of the small hole is only slightly larger than the plastic wire, the size of the knot is larger than the diameter of the small hole and it cannot pass directly. Therefore, manual operation is required to pass the knotted plastic wire through the complex plastic wire transmission roller. The operation is complicated and time-consuming. It is estimated that two staff members will need to operate for more than an hour each time, resulting in low production capacity and labor-intensive.

[0003] In view of this, the purpose of the utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0023] The following is combined with Figure 1-5 The utility model is further described.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0025] Reference Figures 1 to 5 A pole piece scraper plastic wire docking machine comprises a support 1, a hot melt gun 2 and a docking inner cylinder 3, wherein a glue stick 21 is arranged on the hot melt gun 2, wherein the support 1 is used to install the hot melt gun 2 and the docking inner cylinder 3; the docking inner cylinder 3 is a hollow cylindrical structure, and the docking inner cylinder 3 is used to accommodate the plastic wire 6 to be docked; the hot melt gun 2 is used to hot-melt the glue stick 21 and transfer the hot melt glue material to the docking inner cylinder 3 to complete the docking of the ends of the two rolls of plastic wire 6. The docking inner cylinder 3 is rotatably arranged at the bottom of the support 1, and the hot melt gun 2 is installed on the support 1, and the hot melt gun 2 is located on the side of the support 1 away from the docking inner cylinder 3, and the gun nozzle of the hot melt gun 2 faces the docking inner cylinder 3. The docking inner cylinder 3 is provided with an inner cylinder glue injection hole 31 connected to the inside of the docking inner cylinder 3. When the docking inner cylinder 3 is rotated to the state where the inner cylinder glue injection hole 31 is vertically facing upward, the inner cylinder glue injection hole 31 is aligned with the gun nozzle of the hot melt gun 2, that is, at this time, the inner cylinder glue injection hole 31 and the gun nozzle of the hot melt gun 2 are on the same vertical line, and the hot melt glue of the hot melt gun 2 can flow into the docking inner cylinder 3 from the inner cylinder glue injection hole 31. The hot melt gun 2 can be a hot melt gun 2 that heats the plastic wire 6 by extruding a solid glue hot glue or a liquid glue. The type of the hot melt gun 2 is not specifically limited here, and the hot melt gun 2 can be a rechargeable or battery-powered hot melt gun 2.

[0026] When in use, the ends of the two rolls of plastic wire 6 to be connected are respectively inserted into the connecting inner cylinder 3 from the two ends of the connecting inner cylinder 3, and the ends of the two rolls of plastic wire 6 are respectively located at the two ends of the inner cylinder glue injection hole 31. When the glue flows into the connecting inner cylinder 3 from the inner cylinder glue injection hole 31, the glue will fill the gap between the ends of the two plastic wires 6. When the glue is cooled and solidified, the plastic wires 6 can be connected.

[0027] Reference Figures 3 to 5, a glue removing part is provided on the support 1, and the glue removing part is used to scrape off the excess glue at the joint of the two plastic lines 6. In this embodiment, the glue removing part is a docking outer cylinder 4, and the docking outer cylinder 4 is fixedly arranged on the support 1. Specifically, a groove 11 for accommodating the docking outer cylinder 4 is provided at the bottom of the support 1, and the docking outer cylinder 4 is fixedly arranged in the groove 11. The docking outer cylinder 4 is a hollow cylindrical structure, and the docking outer cylinder 4 is sleeved on the outside of the docking inner cylinder 3, and the docking inner cylinder 3 can rotate relative to the docking outer cylinder 4. And the two ends of the docking inner cylinder 3 extend to the outside of the docking outer cylinder 4 respectively, that is, the length of the docking inner cylinder 3 is greater than the length of the docking outer cylinder 4. Such a setting makes it convenient to rotate the docking inner cylinder 3 after the glue injection is completed, so as to reduce the difficulty of operation. It should be noted that in other embodiments, the glue removing part can also be other structures, such as a scraper structure, and the scraper structure is arranged on one side of the docking inner cylinder 3 and aligned with the glue injection hole 31 of the inner cylinder. By rotating the docking inner cylinder 3, the scraper structure scrapes off the excess glue. An outer cylinder glue injection hole 41 connected to the inside of the docking outer cylinder 4 is provided on the side of the docking outer cylinder 4 facing the nozzle of the hot melt gun 2. The docking inner cylinder 3 is rotated. When the inner cylinder glue injection hole 31 on the docking inner cylinder 3 faces the nozzle of the hot melt gun 2, the outer cylinder glue injection hole 41 is aligned with the inner cylinder glue injection hole 31. That is, at this time, the center axis of the outer cylinder glue injection hole 41 and the center axis of the inner cylinder glue injection hole 31 are located on the same straight line. At this time, the hot-melt glue from the hot melt gun 2 can flow from the outer cylinder glue injection hole 41 and the inner cylinder glue injection hole 31 into the docking inner cylinder 3.

[0028] Reference Figures 3 to 5 In the present embodiment, the outer cylinder glue injection hole 41 is in a funnel-shaped structure, and the end with a larger opening faces the hot melt gun 2, and the end with a smaller opening faces the docking inner cylinder 3. The aperture of the inner cylinder glue injection hole 31 is larger than the aperture of the outer cylinder glue injection hole 41 away from the hot melt gun 2. The outer cylinder injection hole is in a funnel-shaped shape to drain the glue. The aperture of the inner cylinder glue injection hole 31 is relatively large, which is conducive to ensuring that the glue flowing into the outer cylinder glue injection hole 41 can all flow into the docking inner cylinder 3 from the inner cylinder glue injection hole 31 without glue leakage, which is conducive to the plastic line docking operation. The inner diameter of the docking outer cylinder 4 is consistent with the outer diameter of the docking inner cylinder 3, that is, the outer wall of the docking inner cylinder 3 is in contact with the inner wall of the docking inner cylinder 3; the inner diameter of the docking inner cylinder 3 matches the wire diameter of the plastic wire 6. In this way, after the glue injection is completed, by rotating the docking inner cylinder 3, the glue injection hole 41 of the outer cylinder is misaligned with the glue injection hole 31 of the inner cylinder, and the excess hot melt glue at the docking point can be scraped off, so that the docking point of the plastic wire 6 is flat and uniform, and it is beneficial to ensure that the diameter of the docking point of the plastic wire 6 is basically consistent with the wire diameter of the plastic wire 6, the operation is simple, and the production efficiency is high.

[0029] Reference Figure 1The pole piece scraper paper plastic wire docking machine also includes a handle 5, which is arranged on the support 1. Specifically, the handle 5 can be fixed to the support 1 or rotatably arranged on the support 1, which is not specifically limited here. The handle 5 is arranged to facilitate transportation, which is conducive to reducing the difficulty of moving the pole piece scraper paper plastic wire docking machine.

[0030] The implementation process of the utility model is:

[0031] Insert the ends of the two rolls of circular plastic wires 6 to be butt-jointed into the butt-jointed inner cylinder 3 from both ends thereof, and make the glue injection port of the inner cylinder 3 located in the middle of the two ends of the plastic wires 6. Then install the glue stick 21 on the hot melt gun 2. Rotate the butt-jointed inner cylinder 3 so that the glue injection hole 31 of the inner cylinder is aligned with the glue injection hole 41 of the outer cylinder. Then turn on the hot melt gun 2 to allow the hot melt glue to flow into the butt-jointed inner cylinder 3. When a certain time has passed, turn off the hot melt gun 2 and rotate the butt-jointed inner cylinder 3 to scrape off excess glue at the joint of the plastic wires 6. This completes the butt-jointing of the plastic wires 6.

[0032] Based on the above structure of the pole piece scraper plastic wire butt joint machine, the utility model also provides:

[0033] A waste glue scraping device for a coating machine comprises a pole piece scraping paper plastic line butt jointing machine with the structure as described above.
