DETAILED DESCRIPTION

[0024] Hereinafter, the preferred embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, the same drawing reference numerals are used for the same elements throughout the several several views. Also, the size ratio between the elements in the drawings and the shape, relative position, and the like of the elements may be exaggerated for clarity and convenience in the related content. It is noted that the directional terms such as upper, lower, left, right, front, rear, and the like are used to merely explain and indicate relative positions between the elements in a certain orientation state, and the directional terms are changed according to the change of the orientation state.

[0025] It is further noted that when an element is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or intervening elements can be present. When an element is referred to as being "connected" another element, it can be directly connected to the other element, or intervening elements can be present.

[0026] Referring to Figure 1 and Figure 2 , the present application provides a winding core processing device, which comprises a frame body 1, a first conveying belt 2 and a first auxiliary member 3. Wherein, the first conveying belt 2 is connected with the frame body 1, and the first conveying belt 2 is used for carrying and conveying the winding core 100; the first auxiliary member 3 is connected with the frame body 1, and the first auxiliary member 3 is located on one side of the first conveying belt 2. The first conveying belt 2 and the first auxiliary member 3 are arranged at intervals, and the first conveying belt 2 can drive the winding core 100 to roll between the first conveying belt and the first auxiliary member 3, and press the circumferential side of the winding core 100.

[0027] With the above structure, when the core processing device is used to process the to-be-rounding core 100, the staff places the to-be-rounding core 100 on the first conveying belt 2, and the to-be-rounding core 100 is extruded by the first conveying belt 2 and the first auxiliary member 3 in the rolling process, so that the diameter of the to-be-rounding core 100 gradually becomes uniform in the rolling and extruding process, and the roundness of the to-be-rounding core 100 gradually tends to be the standard roundness, and there is no obvious protrusion, so that the to-be-rounding core 100 can meet the standard of entering the shell. Therefore, the core processing device can realize the rounding of the to-be-rounding core 100, and the roundness of the to-be-rounding core 100 can be kept highly consistent after the to-be-rounding core 100 is rounded by the core processing device. In addition, the core processing device has high automation degree, and needs less manual operation, so that labor can be saved and work efficiency can be improved.

[0028] In some examples, the distance between the first conveying belt 2 and the first auxiliary member 3 is equal to the maximum outer diameter of the standard core 100. In other words, when the to-be-rounding core 100 is extruded by the first conveying belt 2 and the first auxiliary member 3, since the distance between the first conveying belt 2 and the first auxiliary member 3 is equal, the to-be-rounding core 100 can be uniformly extruded, so that the roundness of the to-be-rounding core 100 gradually tends to be the standard roundness.

[0029] With reference to Figure 4 Generally, the deformed core 100 has an elliptical structure, and the radii of different regions of the deformed core 100 are different with reference to the center of the core 100.

[0030] Taking one deformed core 100 as an example, the maximum diameter of the deformed core 100 is 23 mm, and the minimum diameter is 20 mm, and the maximum outer diameter of the standard core 100 should be 21.5 mm. Therefore, the distance between the first conveying belt 2 and the first auxiliary member 3 is set to 21.5 mm. During the rolling process of the deformed core 100 on the first conveying belt 2, the position with the maximum diameter of 23 mm of the deformed core 100 is continuously extruded by the first conveying belt 2 and the first auxiliary member 3, so that the maximum diameter of the deformed core 100 is reduced to 21.5 mm. The position with the minimum diameter of 20 mm is not extruded, but the diameter of the deformed core 100 at this position also changes slightly due to the deformation of the deformed core 100, and the diameter is also limited by the extrusion of the first conveying belt 2 and the first auxiliary member 3, so it is also not greater than 21.5 mm. When the to-be-rounding core 100 has experienced one round of rolling and extruding, the diameter of the to-be-rounding core 100 gradually becomes uniform, the roundness of the to-be-rounding core 100 gradually tends to be the standard roundness, and there is no obvious protrusion, so that the to-be-rounding core 100 can meet the standard of entering the shell. Of course, some cores 100 with more serious deformation can be extruded for multiple rounds to meet the standard of entering the shell.

[0031] With reference to Figure 4In some embodiments, the first conveying belt 2 and the first auxiliary member 3 further form a whole-circle section 4 and an insertion section 5 in communication with each other, and the insertion section 5 is located upstream of the whole-circle section 4 in the conveying direction of the first conveying belt 2; the distance between the first conveying belt 2 and the first auxiliary member 3 gradually decreases in the conveying direction of the first conveying belt 2 in the insertion section 5; and the distance between the first conveying belt 2 and the first auxiliary member 3 is equal in the whole-circle section 4. Thus, a larger opening is formed between the first conveying belt 2 and the first auxiliary member 3 in the insertion section 5, which facilitates the placement of the core 100 by the staff. Referring to Figure 4 In the insertion section 5, the first conveying belt 2 and the first auxiliary member 3 can form an opening similar to a horn structure. In the whole-circle section 4, the first conveying belt 2 and the first auxiliary member 3 can extrude the core 100 to gradually approach the standard roundness, so that the core 100 does not have a significant protrusion and meets the standard for entering the shell.

[0032] In some examples, the first auxiliary member 3 can have a plate structure, which is defined as a first auxiliary plate for the convenience of description. The first auxiliary plate can be parallel to the outer side of the first conveying belt 2 for carrying the core 100. The core 100 is placed on the first conveying belt 2, and the first conveying belt 2 drives the core 100 to roll forward. The rolling core 100 also rubs against the first auxiliary plate, so that the first auxiliary plate and the first conveying belt 2 extrude and shape the core 100.

[0033] In some embodiments, the first auxiliary member 3 includes a first auxiliary conveying belt 31, and the first conveying belt 2 and the first auxiliary conveying belt 31 are arranged in a spaced manner. The first conveying belt 2 and the first auxiliary conveying belt 31 can drive the core 100 to roll between the first conveying belt and the first auxiliary conveying belt 31, and extrude the peripheral side of the core 100. Thus, the first auxiliary member 3 can not only extrude the core 100, but also cooperate with the first auxiliary conveying belt 31 to assist the first conveying belt 2 in conveying the core 100.

[0034] It should be noted that the core processing device disclosed in the present application further includes a driving assembly 10 for driving the first conveying belt 2 and the first auxiliary conveying belt 31 to move. For example, the driving assembly 10 can include a motor and two gears, which are engaged with the inner side of the first conveying belt 2 and tension the first conveying belt 2. One of the gears is connected to the output shaft of the motor, and the motor is installed on the frame 1. Thus, the motor is started to drive the first conveying belt 2 to convey the core 100. It can be understood that the driving assembly 10 for driving the first auxiliary conveying belt 31 can also use similar components and structures, which will not be described here.

[0035] Reference Figure 4 In some embodiments, the first conveyor belt 2 and the first auxiliary conveyor belt 31 rotate in opposite directions, and the conveying speed of the first conveyor belt 2 is not equal to the conveying speed of the first auxiliary conveyor belt 31. Specifically, such as... Figure 4 The first conveyor belt 2 can rotate counterclockwise, and the first auxiliary conveyor belt 31 can rotate clockwise; their rotation directions are opposite, but the first conveyor belt 2 and the first auxiliary conveyor belt 31 are used to convey the core 100 in the same direction. To ensure that the core 100 can both be conveyed and rotate, the conveying speed of the first conveyor belt 2 is not equal to the conveying speed of the first auxiliary conveyor belt 31; specifically, the speed of the first conveyor belt 2 can be greater than the speed of the first auxiliary conveyor belt 31. Thus, the core 100 can roll and be conveyed forward. Conversely, if the conveying speed of the first conveyor belt 2 is equal to that of the first auxiliary conveyor belt 31, then the first conveyor belt 2 and the first auxiliary conveyor belt 31 will exert a pushing effect on the core 100, conveying it forward, but the core 100 itself will not roll significantly. In this case, the first conveyor belt 2 and the first auxiliary conveyor belt 31 cannot provide a uniform squeezing effect on the core 100, resulting in poor rounding.

[0036] Reference Figure 5 In some embodiments, the first conveyor belt 2 and the first auxiliary conveyor belt 31 rotate in the same direction, and the conveying speed of the first conveyor belt 2 is greater than the conveying speed of the first auxiliary conveyor belt 31. Specifically, such as... Figure 5 The first conveyor belt 2 and the first auxiliary conveyor belt 31 can both rotate counterclockwise, with the same rotation direction, but their directions of action on the core 100 are opposite. In this embodiment, the conveying speed of the first conveyor belt 2 is greater than that of the first auxiliary conveyor belt 31. Therefore, the first conveyor belt 2 mainly functions to convey the core 100, while the first auxiliary conveyor belt 31, in conjunction with the first conveyor belt 2, can compress the core 100 and cause it to rotate. During conveying, if both the first conveyor belt 2 and the first auxiliary conveyor belt 31 rotate counterclockwise, the core 100 can rotate clockwise. However, since the conveying speed of the first conveyor belt 2 is greater than that of the first auxiliary conveyor belt 31, the conveying speed of the first auxiliary conveyor belt 31 can also be very slow. Therefore, the core 100 can still be conveyed forward under the drive of the first conveyor belt 2.

[0037] Reference Figure 3In some embodiments, the winding core processing device further comprises a first limiting member 6 connected to the frame body 1; the first limiting member 6 is arranged opposite to the whole circle section 4 and extends along the length direction of the first auxiliary conveying belt 31, and the first limiting member 6 abuts against the inner side of the first auxiliary conveying belt 31 so that the outer side of the first auxiliary conveying belt 31 extrudes the winding core 100. In this way, the first limiting member 6 can limit the elastic deformation of the first auxiliary conveying belt 31 and also play a role of tensioning the first auxiliary conveying belt 31. It can be understood that the first auxiliary conveying belt 31 has a certain elasticity, and the elastic deformation of the first auxiliary conveying belt 31 can easily reduce the extrusion effect on the winding core 100, and therefore, the first limiting member 6 can make the first auxiliary conveying belt 31 better extrude the winding core 100.

[0038] With reference to Figure 3 In some embodiments, the winding core processing device further comprises a second limiting member 7; the second limiting member 7 abuts against the inner side of the first auxiliary conveying belt 31, and the second limiting member 7 is arranged opposite to the placing section 5; the second limiting member 7 is arc-shaped, and the distance between the second limiting member 7 and the first conveying belt 2 gradually decreases along the conveying direction of the first conveying belt 2. In this way, the second limiting member 7 limits the deformation of the first auxiliary conveying belt 31 and can shape the first auxiliary conveying belt 31, so that the first auxiliary conveying belt 31 and the first conveying belt 2 can form an opening similar to a horn structure.

[0039] In some examples, the second limiting member 7 can be connected to the frame body 1. In other examples, the second limiting member 7 can be integrally formed with the first limiting member 6. In other examples, the second limiting member 7 can be fixedly connected or detachably connected with the first limiting member 6.

[0040] In some embodiments, the winding core processing device further comprises a first tensioning member connected to the frame body 1, and the first tensioning member abuts against the inner side or the outer side of the first conveying belt 2. In this way, the first tensioning member can sufficiently tension the first conveying belt 2, so as to better extrude the winding core 100.

[0041] With reference to Figures 1 to 3 In some embodiments, the winding core processing device further comprises a second tensioning member 8 connected to the frame body 1, and the second tensioning member 8 abuts against the inner side or the outer side of the first auxiliary conveying belt 31. In this way, the second tensioning member 8 can sufficiently tension the first auxiliary conveying belt 31, so as to better extrude the winding core 100.

[0042] In some embodiments, the frame 1 comprises a plurality of first adjustment positions near the first conveying belt 2, and the first tensioning member is detachably connected to any one of the first adjustment positions. In this way, the first tensioning member can be connected to different first adjustment positions, and different degrees of tensioning of the first conveying belt 2 can be achieved at different first adjustment positions. It can be understood that the first conveying belt 2 is prone to become loose and the degree of tensioning decreases after a long time of use. Therefore, the first tensioning member can be arranged at different positions according to the degree of looseness of the first conveying belt 2, so as to adjust the degree of tensioning of the first conveying belt 2.

[0043] In some embodiments, the frame 1 comprises a plurality of second adjustment positions near the first auxiliary conveying belt 31, and the second tensioning member 8 is detachably connected to any one of the second adjustment positions. In this way, the second tensioning member 8 can be connected to different second adjustment positions, and different degrees of tensioning of the first auxiliary conveying belt 31 can be achieved at different second adjustment positions. It can be understood that the first auxiliary conveying belt 31 is prone to become loose and the degree of tensioning decreases after a long time of use. Therefore, the second tensioning member 8 can be arranged at different positions according to the degree of looseness of the first auxiliary conveying belt 31, so as to adjust the degree of tensioning of the first auxiliary conveying belt 31.

[0044] Referring to Figure 2 and Figure 3 In some embodiments, the core processing device further comprises a collecting member 9 connected to the frame 1, and the collecting member 9 is located at the end of the first conveying belt 2 in the conveying direction of the first conveying belt 2, and is used for collecting the cores 100. In this way, the cores 100 after completing a round of conveying and extruding are conveyed out of the first conveying belt 2. Therefore, the arrangement of the collecting member 9 can collect the cores 100, and facilitate subsequent unified processing of the cores 100 by the workers.

[0045] The application also provides a core processing device, which comprises: a frame 1; a second conveying belt connected to the frame 1; a second auxiliary member connected to the frame 1, the second auxiliary member being used for carrying the cores 100, and the second auxiliary member being located on one side of the second conveying belt; and the second conveying belt and the second auxiliary member are arranged at intervals, the second conveying belt can drive the cores 100 to roll between the second conveying belt and the second auxiliary member, and extrude the circumferential side of the cores 100.

[0046] In some examples, the second auxiliary member can be in a plate structure, for the sake of description, the second auxiliary member in the plate structure is defined as a second auxiliary plate. The second auxiliary plate can be parallel to the outer side of the second conveying belt for conveying the winding core 100. The winding core 100 is placed on the second auxiliary plate, the second conveying belt drives the winding core 100 to roll forward, and the rolling winding core 100 also rubs against the second auxiliary plate, so as to realize the extrusion and shaping of the winding core 100 between the second auxiliary plate and the second conveying belt.

[0047] In summary, when the winding core processing device is used to process the winding core 100 to be rounded, the winding core 100 can be rolled and extruded on the circumferential side of the winding core 100, so that the diameter of the circumferential side of the winding core 100 gradually becomes uniform in the rolling and extruding, the roundness of the winding core 100 gradually tends to be a standard roundness, and there is no obvious protrusion, so that the standard of the winding core 100 into the shell can be achieved. Therefore, the winding core processing device involved in the present application can realize the rounding of the winding core 100, and the roundness of the winding core 100 after being rounded by the winding core processing device can be kept highly consistent. In addition, the winding core processing device has high automation degree, and needs less manual operation, which can save labor and improve work efficiency.
