Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plating machines, in particular to a wire feeding device for aluminum plating machines which can prevent wire jams. Background Art

[0002] Vacuum aluminum film is a bright metallic film formed by evaporating high-purity aluminum wire into gas at high temperature through vacuum aluminum plating process. When the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules are precipitated on the surface of the plastic film. Because it has the characteristics of both plastic film and metal, it is a cheap, beautiful, high-performance and practical packaging material. In the production process of aluminum plating film on the film by the aluminum plating machine, the stable and uniform feeding of aluminum wire is a prerequisite for ensuring the thickness of the aluminum layer, appearance and other important indicators, so as to ensure the quality of the aluminum plating film.

[0003] At present, the wire feeding device of the commonly used aluminum plating machine is driven by the wire feeding control system to drive the wire feeding motor to feed the wire. Generally, the synchronous wheel and the driven wheel are used to drive the aluminum wire, so that the aluminum wire is sent from the wire reel through the wire feeding device and then enters the vacuum evaporation boat to evaporate into gaseous aluminum vapor at high temperature. However, when this type of wire feeding device is feeding the wire, due to the change of the wire feeding angle and friction force of the aluminum wire on the wire reel, the aluminum wire is prone to slipping on the synchronous wheel during the wire feeding process, and the driven wheel is also prone to slipping when contacting the aluminum wire, which can easily cause the aluminum wire to get stuck during the wire feeding process, and then produce undesirable phenomena such as whitening and aluminum explosion of aluminum plating, which not only causes the quality of the aluminum plating film to decline, but also forces the aluminum plating machine to be shut down for maintenance, resulting in loss of working hours, products and consumables. Utility Model Content

[0004] In order to solve the technical problems in the prior art that aluminum wire is easily stuck during the wire feeding process, resulting in undesirable phenomena such as whitening and aluminum explosion during aluminum plating, which causes the quality of aluminum-plated film products to decline, and the aluminum plating machine has to be shut down for maintenance, resulting in loss of working hours, products and consumables, the utility model provides the following technical solutions.

[0005] The utility model discloses a wire feeding device for an aluminum plating machine to prevent wire jamming, comprising a base and a wire winding reel located on one side of the base, wherein one side of the wire winding reel is provided with a shell body with a top connected to a cover body, and the front and rear sides of the shell are provided with a wire guide tube and a wire outlet tube, and the wire guide tube comprises a tube body fixed to the shell and a bell mouth located at one end of the tube body facing the wire winding reel. The shell is connected with a driving component, and the driving component comprises a wire feeding motor located on one side of the shell and a synchronous belt structure connected to the output end of the wire feeding motor, and the synchronous belt structure is connected with at least two driving wheels, and an equal number of driven wheels are provided above the driving wheel, and the driven wheel is rotatably connected to an inverted U-shaped positioning bracket slidably connected to the shell, and adjacent positioning brackets are connected to a fixing plate, and the upper end of the positioning bracket is connected to a pre-tightening component through a telescopic component, and the pre-tightening component moves up and down to adjust the pre-tightening force on the aluminum wire between the driven wheel and the driving wheel, so as to facilitate smooth transportation of the aluminum wire.

[0006] As a further technical solution, the positioning bracket includes two vertical parts rotatably connected to the driven wheel and a transverse part fixedly connected to the telescopic part. Positioning sliders extend from both ends of the transverse part, and the positioning sliders are slidably connected to the positioning grooves provided on the inner wall of the shell.

[0007] As a further technical solution, the pre-tightening component includes an adjusting screw with a handle, the adjusting screw is threadedly connected and passes through the cover body to be connected to a pre-tightening pressure plate, and the pre-tightening pressure plate is connected to the telescopic component.

[0008] As a further technical solution, the telescopic component includes a telescopic sleeve fixedly connected to the positioning bracket and the pre-tightening plate, and a spring sleeved on the outer circumference of the telescopic sleeve.

[0009] As a further technical solution, the driven wheel is provided with a frosted groove that fits the aluminum wire.

[0010] The utility model has the beneficial effect that the driving component of the utility model synchronously drives at least two driving wheels to cooperate with the same number of driven wheels to feed aluminum wire, the driving wheel is rotatably connected to the inner wall, the driven wheel is rotatably connected to a positioning bracket, the positioning bracket is slidably connected to the inner wall of the inner shell, and a fixing plate is connected between adjacent positioning brackets. During the wire feeding process, the driving wheel and the driven wheel are not easy to offset and slide due to the force of the aluminum wire in the horizontal direction and the vertical direction, thereby improving the operation stability between the driven wheel and the driving wheel during the wire feeding process. The positioning bracket is connected to the pre-tightening component through a telescopic component, and the pre-tightening component adjusts the pre-tightening force between the driving wheel and the driven wheel on the aluminum wire. Even if the angle and friction of the aluminum wire change slightly during the wire feeding process, it will not cause wire jamming, thereby improving the stability of the wire feeding process. A wire guide tube is arranged between the wire reel and the shell, and a bell mouth is arranged at one end of the wire guide tube close to the wire reel. As the thickness of the aluminum wire of the wire reel decreases and the forward angle of the aluminum wire changes, the bell mouth design of the wire guide tube can also reduce the friction between the aluminum wire and the wire guide tube, thereby improving the stability of the wire feeding process and preventing wire jamming.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower" and "both sides" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second" and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] like Figure 1 and Figure 2 As shown, the utility model is a wire feeding device for an aluminum plating machine to prevent wire jamming, comprising a base 1 and a wire reel 2 located on one side of the base 1, a housing 4 is provided on one side of the wire reel 2, and a cover 401 is provided on the top of the housing 4. A wire guide tube 3 and a wire outlet tube 10 are provided on the front and rear sides of the housing 4 on the aluminum wire feeding path, respectively. After the aluminum wire comes out of the wire reel 2, it enters the housing 4 through the wire guide tube 3 for wire feeding, and then comes out from the wire outlet tube 10 and enters the vacuum evaporation chamber.

[0019] The wire guide tube 3 includes a tube body 301 fixed to the housing 4 and a bell mouth 302 at one end of the tube body 301 facing the wire reel 2. As the thickness of the aluminum wire on the wire reel 2 decreases, the advancing angle of the aluminum wire will change, and the friction force will change when the aluminum wire enters the wire guide tube 3. At this time, the design of the bell mouth 302 of the wire guide tube 3 can adapt to the change of the aluminum wire angle, reduce the friction force between the aluminum wire and the wire guide tube, improve the stability of the wire feeding process, and prevent wire jamming.

[0020] like Figure 2 and Figure 3As shown, in a preferred embodiment, the housing 4 is a hollow structure, and the housing 4 is connected to a driving component 5, and the driving component 5 includes a wire feeding motor 501 located on one side of the outside of the housing 4, and the output end of the wire feeding motor 501 is connected to a synchronous belt structure 502. Specifically, the side wall of the housing 4 is rotatably connected to two synchronous wheels, and a synchronous belt is connected between the two synchronous wheels, and one side constitutes a synchronous belt structure 502. The synchronous belt structure 502 is connected to two driving wheels 503, and the other side of the driving wheel 503 is rotatably connected to the other side wall of the housing 4. An equal number of driven wheels 504 are arranged above the driving wheel 503, and the driven wheel 504 is rotatably connected to an inverted U-shaped positioning bracket 6 that is slidably connected to the housing 4, and the adjacent positioning bracket 6 is connected to a fixing plate 7. As a result, the driving wheel 503 and the driven wheel 504 are not easily offset and slid in the horizontal direction and the vertical direction due to the force of the aluminum wire, thereby improving the running stability between the driven wheel and the driving wheel during the wire feeding process. The upper end of the positioning bracket 6 is connected to a pre-tightening component 9 through a telescopic component 8. The pre-tightening component 9 moves up and down to adjust the pre-tightening force on the aluminum wire between the driven wheel 504 and the driving wheel 503, so as to facilitate the smooth transportation of the aluminum wire.

[0021] In a preferred embodiment, the positioning bracket 6 includes two vertical parts 601 rotatably connected to the driven wheel 504 and a transverse part 602 fixedly connected to the telescopic part 8, and positioning sliders 603 extend from both ends of the transverse part 602, and the positioning sliders 603 are slidably connected to the positioning slide grooves 402 provided on the inner wall of the shell 4. When the pre-tightening component 9 adjusts the pre-tightening force, the positioning bracket 6 can move up and down to adjust the pre-tightening force on the aluminum wire between the driven wheel 504 and the driving wheel 503. Therefore, when the pre-tightening component 9 adjusts the pre-tightening force and during the wire feeding process, the driven wheel 504 will not deviate. At the same time, the driven wheel 504 is provided with a frosted groove 505 that fits the aluminum wire. The setting of the frosted groove 505 can further prevent the driven wheel 504 and the aluminum wire from slipping and prevent the occurrence of wire jamming.

[0022] In a preferred embodiment, the pre-tightening component 9 includes an adjusting screw 902 provided with a handle 901, the adjusting screw 902 is threadedly connected to the cover body 401, and is rotatably connected to a pre-tightening plate 903 through the cover body 401, and the pre-tightening plate 903 is connected to the telescopic component 8. The telescopic component 8 includes a telescopic sleeve 801 fixedly connected to the positioning bracket 6 and the pre-tightening plate 903, and a spring 802 sleeved on the outer periphery of the telescopic sleeve 801. When the handle 901 is screwed, the adjusting screw 902 spirals downward and pushes the pre-tightening plate 903, and the pre-tightening plate 903 pushes the telescopic component 8 and the positioning bracket 6, completing the pre-tightening force of the driving wheel 503 and the driven wheel 504 on the aluminum wire.

[0023] When the utility model is in use, the aluminum wire of the wire reel 2 is inserted from the bell mouth 302 of the wire guide tube 3 and extended to between the active wheel 503 and the driven wheel 504, and then passes through the wire outlet tube 10 and penetrates into the vacuum evaporation chamber, the pre-tightening component 9 is screwed, and the pre-tightening pressure plate 903 of the pre-tightening component 9 pushes the telescopic component 8 and the positioning bracket 6 to move downward, completing the pre-tightening force adjustment of the active wheel 503 and the driven wheel 504 on the aluminum wire, and then the driving component 5 is started to start wire feeding.

[0024] The preferred specific implementation modes and embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation modes and embodiments, and various changes or equivalent substitutions can be made within the knowledge scope of those skilled in the art without departing from the concept of the utility model.
