Description

Technical Field

[0001] This utility model belongs to the field of electrical and capacitor technology, and in particular relates to a capacitor core bundle pretreatment device based on a strapping machine. Background Technology

[0002] Capacitors play an important role in circuits for tuning, bypassing, coupling, and filtering. They are also a common electrical component in industrial production. Inside a capacitor is a capacitor core, which is wrapped with multiple layers of insulating paper and secured with straps to hold the insulating paper and capacitor core in place.

[0003] Strapping machines are existing technology and are also known as strapping machines, packing machines, etc. CN112340090A discloses a strapping machine, CN207258043U discloses a semi-automatic strapping machine, CN219904832U discloses a semi-automatic packing machine that facilitates the replacement of packing straps, CN114933045B discloses a strapping machine, CN107499560A discloses a semi-automatic packing machine for heat dissipation boxes, and CN210761462U discloses a semi-automatic strapping machine. All of the above are existing strapping machines or similar equipment.

[0004] Strapping machines typically include a base, a strap feeder, a strap take-up device, and a strap guide groove on the base. The strap feeder has a strap feeding port, and the strap take-up device has a strap taking-up port. When using a strapping machine, the strap feeder delivers the strap from the strap feeding port, with the free end of the strap passing through the strap guide groove. The operator places the object to be packaged on the base (the object is above the strap guide groove), then holds the free end of the strap and allows it to wrap around the object from above. The free end of the strap is then inserted into the strap take-up port, and the strapping machine (snap take-up device) automatically tightens the strap and completes the heat fusion (forming a strap loop). One object is now strapped. The strapping machine also automatically cuts the strap loop from the remaining straps. Afterward, the operator removes the strapped object, and the strap feeder restarts, delivering the strap from the strap feeding port again, with the free end of the strap passing through the strap guide groove, ready for a new strapping operation.

[0005] However, the capacitor cores are wrapped with insulating paper on a wrapping machine. After wrapping, the capacitor cores are heavy and difficult to move. Also, the wrapped insulating paper is prone to unraveling during the handling and placement on the strapping machine, which makes subsequent strapping operations difficult. Therefore, it is more reasonable to prefabricate the strapping rings and then put the strapping rings on the wrapped capacitor cores. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown,

[0027] A capacitor core strapping pretreatment device based on a strapping machine, the strapping machine includes a base 1, a strap feeder, a strap take-up device, and a strap feeding guide groove 1a disposed on the base 1. The strap feeder has a strap feeding port, the strap take-up device has a strap taking-up port, and the strap taking-up port is connected to the bottom of the strap feeding guide groove 1a. In the length direction of the strap feeding guide groove 1a: one end of the strap feeding guide groove 1a is connected to the strap feeding port, and the other end of the strap feeding guide groove 1a is the free end outlet of the strap.

[0028] It also includes a fixed guide rail 2 fixed relative to the base 1, an outer bundle plate 2.1 that slides with the fixed guide rail 2, a movable moving guide rail 3, an inner bundle plate 3.1 that slides with the moving guide rail 3, and a drive mechanism for driving the moving guide rail 3 to move. The moving direction of the moving guide rail 3 is parallel to the length direction of the bundle delivery groove 1a, the sliding direction of the outer bundle plate 2.1 is horizontal and perpendicular to the length direction of the bundle delivery groove 1a, and the sliding direction of the inner bundle plate 3.1 is parallel to the sliding direction of the outer bundle plate 2.1.

[0029] The outer wrapping plate 2.1 and the inner wrapping plate 3.1 are symmetrically arranged along a vertical plane. The side of the outer wrapping plate 2.1 away from the inner wrapping plate 3.1 is the outer plate working surface 2.1a, and the side of the inner wrapping plate 3.1 away from the outer wrapping plate 2.1 is the inner plate working surface 3.1a. The upper end of the outer wrapping plate 2.1, the lower end of the outer wrapping plate 2.1, and the beam feeding guide groove 1a are arranged sequentially from top to bottom. The beam receiving port, the outer plate working surface 2.1a, the fixed guide rail 2, the moving guide rail 3, and the inner plate working surface 3.1a are arranged sequentially along the length direction of the beam feeding guide groove 1a.

[0030] When it is necessary to manufacture the strap ring, first determine the position of the inner strapping plate 3.1 based on the required diameter (inner diameter) of the strap ring. Specifically, the diameter of the strap ring = height of the inner strapping plate 3.1 + height of the outer strapping plate 2.1 + 2 times (distance between the inner working surface 3.1a and the outer working surface 2.1a).

[0031] When the strapping machine is working, the strap feeder sends the strapping tape out from the strap feeding port. The free end of the strapping tape passes through the strap feeding guide groove 1a (the strapping tape passes below the outer wrapping plate 2.1 and below the inner wrapping plate 3.1). Figure 1 From the perspective, the free end of the strap will be on the left side of the inner wrapping plate 3.1. Then, the operator can hold the free end of the strap and let the strap pass over the inner wrapping plate 3.1 and the outer wrapping plate 2.1 from above (the strap also passes over the inner plate working surface 3.1a and the outer plate working surface 2.1a). Then, insert the free end of the strap into the gathering port. The strapping machine (gathering device) will automatically tighten the strap and complete the heat fusion (forming a strap loop). One strap loop is then made. The strapping machine will also automatically cut the strap loop from the other straps (the made strap loop is then fitted onto the inner wrapping plate 3.1 and the outer wrapping plate 2.1 and is in a taut state).

[0032] When the cable feeder operates again, it will deliver the cable tie from the cable feed port. The free end of the cable tie passes through the cable feed guide groove 1a, ready for the next cable tie ring fabrication operation. Before the next cable tie ring fabrication operation, the operator can manually pull the inner cable tie plate 3.1 and the outer cable tie plate 2.1 outwards slightly. In this way, the cable tie ring fabricated in the previous operation will move away from directly above the cable feed guide groove 1a as the inner cable tie plate 3.1 and the outer cable tie plate 2.1 move, without affecting the fabrication of the next cable tie ring. When multiple pre-made strap loops are already fitted onto the inner strapping plate 3.1 and the outer strapping plate 2.1, and there is insufficient space to fit new strap loops onto them, the drive mechanism can be used to move the guide rail 3 and the inner strapping plate 3.1 together, bringing the inner strapping plate 3.1 closer to the outer strapping plate 2.1. In this way, the strap loops fitted onto the inner strapping plate 3.1 and the outer strapping plate 2.1 will no longer be taut and can be easily removed.

[0033] The fixed guide rail 2 includes at least two parallel fixed guide bars 201, and the outer binding plate 2.1 is slidably connected to the fixed guide bars 201. The moving guide rail 3 includes at least two parallel moving guide bars 301, and the inner binding plate 3.1 is slidably connected to the moving guide bars 301.

[0034] Multiple fixed guide bars 201 can ensure the guiding effect and improve the stability of the outer bundle plate 2.1 when sliding; multiple moving guide bars 301 can ensure the guiding effect and improve the stability of the inner bundle plate 3.1 when sliding.

[0035] The driving mechanism includes a drive frame 401, a drive seat 402 slidably connected to the drive frame 401, a rotating lead screw 403 threadedly engaged with the drive seat 402, and a lead screw motor 404 that drives the rotating lead screw 403. The sliding direction of the drive seat 402 is parallel to the length direction of the feed guide groove 1a, and the drive seat 402 is fixed relative to the moving guide rail 3.

[0036] The lead screw motor 404 drives the rotating lead screw 403 to rotate. Since the rotating lead screw 403 is threadedly engaged with the drive seat 402 and the drive seat 402 is slidably connected with the drive frame 401, the drive seat 402 will slide along the drive frame 401, which will drive the moving guide rail 3 and the inner binding plate 3.1 to move together, so that the distance between the inner binding plate 3.1 and the outer binding plate 2.1 becomes smaller or larger.

[0037] The inner wrapping plate 3.1 has a lifting horizontal tube 5 and a lifting motor 5.1 for driving the lifting horizontal tube 5 to rotate on one side. One end of the lifting horizontal tube 5 faces the end outlet of the strap. The top of the lifting horizontal tube 5 has a lifting notch 5a5a for the strap to pass through. The lifting horizontal tube 5, the inner wrapping plate 3.1 and the outer wrapping plate 2.1 are arranged in sequence along the length direction of the strap delivery guide groove 1a. In the axial direction of the lifting horizontal tube 5: the lifting notch 5a penetrates the lifting horizontal tube 5.

[0038] When the lifting horizontal tube 5 is rotated to the lifted state: the lifting horizontal tube 5 is vertical, and the upper end of the lifting horizontal tube 5, the inner wrapping plate 3.1 and the lower end of the lifting horizontal tube 5 are arranged from top to bottom.

[0039] Originally, when the operator held the free end of the strap to go around the inner strapping plate 3.1 and the outer strapping plate 2.1, the operator needed to first move to one side of the inner strapping plate 3.1, move their hand to the lower inside of the inner strapping plate 3.1 (lower on the side away from the outer strapping plate 2.1), and bend down to pick up the free end of the strap before going around the inner strapping plate 3.1 and the outer strapping plate 2.1. In this solution, after the free end of the strap passes through the strap feeding guide groove 1a, it will eventually pass through the lifting horizontal tube 5. Then, the lifting motor 5.1 will drive the lifting horizontal tube 5 to rotate. During rotation, the end of the lifting horizontal tube 5 away from the inner strapping plate 3.1 moves upward until the lifting horizontal tube 5 rotates to the lifted state (e.g., Figure 5As shown in the diagram, at this point, the lifting tube 5 is vertical, and the free end of the strap is also above the upper end of the lifting tube 5 (higher than the inner binding plate 3.1). The operator does not need to bend over or move their hand to the lower inner side of the inner binding plate 3.1, but can directly grasp the free end of the strap at the upper end of the lifting tube 5 to perform subsequent operations of bypassing the inner binding plate 3.1 and the outer binding plate 2.1 (the strap will leave the lifting tube 5 through the lifting notch 5a). Therefore, the overall convenience of the operation is greatly improved. After the strap ring is made once, the lifting tube 5 is reset to prepare for the next strap ring making.

[0040] The base 1 is provided with a support seat 1.1 and an extension plate 1.2 slidably connected to the base 1. The extension plate 1.2 is in sliding contact with the support seat 1.1. The sliding direction of the extension plate 1.2 is parallel to the length direction of the beam delivery guide groove 1a. The extension plate 1.2 and the base 1 are self-locking due to friction. The extension plate 1.2 is provided with a transition guide groove 1.2c. The bottom surface of the transition guide groove 1.2c is lower than the bottom surface of the beam delivery guide groove 1a. The highest point of the inner wall of the beam lifting horizontal tube 5, the bottom surface of the transition guide groove 1.2c, and the lowest point of the inner wall of the beam lifting horizontal tube 5 are arranged from top to bottom. In the sliding direction of the extension plate 1.2, the beam lifting horizontal tube 5, one end of the extension plate 1.2, the end outlet of the beam belt, and the other end of the extension plate 1.2 are arranged in sequence.

[0041] The extension plate 1.2 can be used for transition. After the free end of the strapping passes through the feed guide groove 1a, it will continue to pass through the transition guide groove 1.2c on the extension plate 1.2, and then smoothly enter the lifting cross tube 5. The extension plate 1.2 can be pulled out or pushed back (the extension plate 1.2 is slidably connected to the base 1, and the extension plate 1.2 and the base 1 are frictionally self-locking). That is, according to the position of the inner strapping plate 3.1, the operator can manually control the length of the extension plate 1.2 extending out of the base to adapt.

[0042] The lifting motor 5.1 drives the lifting horizontal tube 5 to rotate through the connecting seat 5.2. The extension plate 1.2 is provided with an upper notch 1.2a for avoiding the lifting horizontal tube 5 and a lower notch 1.2b for avoiding the connecting seat 5.2. The upper end of the lower notch 1.2b is connected to the lower end of the upper notch 1.2a. The highest point of the inner wall of the lifting horizontal tube 5, the lower end of the upper notch 1.2a, and the lowest point of the inner wall of the lifting horizontal tube 5 are arranged from top to bottom. When the lifting horizontal tube 5 rotates to the lifted state: the lower end of the lifting horizontal tube 5 is inside the upper notch 1.2a, and the connecting seat 5.2 passes through the lower notch 1.2b.

[0043] Example 2: Based on Example 1, such as Figure 6 As shown,

[0044] Above the lifting beam notch 5a, there are multiple spring-loaded baffles 5.3 that cross the lifting beam notch 5a. The spring-loaded baffles 5.3 are arranged horizontally, and one end of the spring-loaded baffles 5.3 is connected to the lifting beam horizontal tube 5. Each spring-loaded baffle 5.3 is arranged sequentially along the axial direction of the lifting beam horizontal tube 5.

[0045] During the rotation of the lifting tube 5 to the lifted state, the strap may be thrown out of the lifting tube 5 (the strap is thrown out of the lifting tube 5 through the lifting notch 5a). Therefore, multiple spring-loaded baffles 5.3 are provided to prevent the strap from being thrown out of the lifting tube 5. When the operator holds the free end of the strap to pass around the inner wrapping plate 3.1 and the outer wrapping plate 2.1, since the operator is pulling the strap out of the lifting tube 5, the strap can push aside the spring-loaded baffles 5.3 and leave the lifting tube 5 through the lifting notch 5a. The spring-loaded baffles 5.3 will then automatically and elastically return to their original position.

[0046] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
