Description

Technical Field

[0001] The utility model relates to the technical field of bead chain machines, in particular to a bead chain machine with doubled output. Background Art

[0002] Bead chains are widely used as a means to string ornaments or directly as decorations. The production machines for bead chains (bead chain machines) are basically fully automatic. The existing structure of bead chain machines mainly includes a rotating shaft, a power and transmission mechanism, a stamping and forming mechanism, and a feeding mechanism. The power and transmission mechanism transmits power to the rotating shaft to drive the rotating shaft to rotate. The stamping and forming mechanism is provided with a sliding stamping block and upper and lower stamping dies. The upper stamping die is fixed on the stamping block. A cam that abuts against the upper stamping die is also provided on the rotating shaft to drive the stamping block to drive the upper stamping die to perform a stamping action; the feeding mechanism includes a material discharging tray and a progressive feeding mechanism. The progressive feeding mechanism is provided with a material tape clamping mechanism. The material tape clamping mechanism is provided with a clamping part that moves back and forth along the feeding direction. When the clamping part moves forward, it clamps the material tape, and when it returns, it loosens the material tape, thereby achieving the purpose of progressive feeding.

[0003] Currently, quite a number of patent technologies regarding bead chain machines have been publicly disclosed. For example, Chinese Patent Publication No. CN203764847U discloses a bead chain machine. The specific solution is as follows: It includes a rotating shaft, a power device and a transmission mechanism, a first stamping and forming mechanism, a first progressive feeding mechanism, a second stamping and forming mechanism, and a second progressive feeding mechanism. A chain rope stamping block and a chain rope die are provided in the first stamping and forming mechanism. A chain bead stamping block and a chain bead die are provided in the second stamping and forming mechanism. The stamping and forming mechanisms are both provided with a sliding stamping block. A cam that abuts against the stamping block is also provided on the rotating shaft to drive the stamping block. The first stamping and forming mechanism, the first progressive feeding mechanism, the second stamping and forming mechanism, and the second progressive feeding mechanism are arranged on the same machine frame. Compared with the prior art, since this bead chain machine is provided with two sets of stamping and forming mechanisms and progressive feeding mechanisms, and the power is transmitted to the rotating shaft to drive the rotating shaft by sharing the same power device and transmission mechanism, the structure is more compact, the cost is lower, and it is more energy-saving.

[0004] However, from the description of the existing bead chain machines in the above patent, it can be seen that the second stamping and forming mechanism is used for stamping chain beads, and all adopt the design principle of one product per stroke, that is, when the rotating shaft and the rotating wheel rotate one circle, only one bead can be produced, a rotating principle structure of one rotation and one output. However, the output and efficiency of this kind of structure are not high. Based on this, it is necessary to disclose a bead chain machine with doubled output to overcome the defects of the prior art. Summary of the Utility Model

Detailed implementation manner

[0027] The following describes the preferred embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0028] As Figures 1 to 5 shown, a bead chain machine with doubled output includes: a frame 1 and a rotating shaft 2. A first fixed plate member 3, a second fixed plate member 4, and a third fixed plate member 5 are arranged on the frame 1. The first fixed plate member 3, the second fixed plate member 4, and the third fixed plate member 5 are longitudinally parallel to each other in pairs. The rotating shaft 2 is rotatably connected to the first fixed plate member 3, the second fixed plate member 4, and the third fixed plate member 5 through bearings. The first fixed plate member 3, the second fixed plate member 4, and the third fixed plate member 5 are longitudinally parallel to each other in pairs, so that the three have a good load-bearing effect on the rotating shaft 2. This longitudinal load-bearing makes the force centers of the first fixed plate member 3, the second fixed plate member 4, and the third fixed plate member 5 all perpendicular, and the force will be better.

[0029] The rotating shaft 2 is horizontally rotatably connected to the first fixed plate member 3, the second fixed plate member 4, and the third fixed plate member 5. The area between the first fixed plate member 3 and the second fixed plate member 4 is a traction and fixing area, and the area between the second fixed plate member 4 and the third fixed plate member 5 is a stamping area. The traction and fixing area is used to draw the strip material in, and then stamp it into chain beads in the stamping area. Two or more rotating pressing wheels 25 are connected to the rotating shaft 2, and the rotating pressing wheels 25 are located in the stamping area. The stamping area has a sliding cavity 6, and the sliding cavity 6 has a stamping block 7. The upper end of the stamping block 7 abuts against the rotating pressing wheel 25, and the lower end of the stamping block 7 is connected to an upper pressing module 8. A bearing module 9 is arranged directly below the upper pressing module 8, and the bearing module 9 is fixed on the frame 1. That is, the rotation of the rotating shaft 2 will drive the two rotating pressing wheels 25 to rotate simultaneously. The outer contour of the rotating pressing wheel 25 is non-circular, that is, similar to an elliptical shape. Therefore, the rotation of the rotating pressing wheel 25 will press down on the stamping block 7, and the stamping block 7 controls the upper pressing module 8 to press down into the bearing module 9. The upper pressing module 8 is the upper die equipped with a mold, and the bearing module 9 is the lower die equipped with a mold. The strip material is conveyed between the upper die and the lower die of the mold. Therefore, the above-mentioned downward pressure will punch out chain beads from the strip material.

[0030] The traction fixing area is provided with a feeding force arm 10 and a progressive feeding component. The feeding force arm 10 is pivotally connected to the frame 1. An upper arm driving member 11 is arranged on the rotating shaft 2. The upper end of the feeding force arm 10 is movably connected to the upper arm driving member 11, and the lower end of the upper end of the feeding force arm 10 is connected to the progressive feeding component. A first bearing 12 is rotatably connected to the upper end of the feeding force arm 10, and a second bearing 13 is rotatably connected to the lower end of the feeding force arm 10.

[0031] A convex block 14 is arranged on the side surface of the upper arm driving member 11. The convex block 14 is provided with a semi-circular convex arc surface, and the first bearing 12 is connected to the semi-circular convex arc surface. The number of the convex blocks 14 is two, and the virtual connection line between the two convex blocks 14 coincides with the virtual diameter of the rotating shaft 2. The rotation of the rotating shaft 2 drives the upper arm driving member 11 to rotate, so that the convex block 14 touches the first bearing 12, thereby enabling the feeding force arm 10 to swing.

[0032] The progressive feeding component includes a feeding seat 15. A feeding shaft 16 with a hollow design is arranged on the feeding seat 15 in a transverse sliding manner. One end of the feeding shaft 16 is connected with a clamping portion 17, and the other end of the feeding shaft 16 is connected with a linkage disk 18. A discharging port is formed in the middle of the clamping portion 17, and a feeding port is formed in the middle of the linkage disk 18. The feeding port, the hollow portion of the feeding shaft 16, and the discharging port are communicated with each other. The strip material enters from the feeding port formed in the middle of the linkage disk 18 and is finally output from the discharging port of the clamping portion 17. When the clamping portion 17 moves forward, it clamps the strip material, and when it returns, it loosens the strip material, thereby achieving the function of feeding the strip material. A spring 19 is sleeved on the feeding shaft 16, and the spring 19 has a pressing force on the clamping portion 17 to enable the clamping portion 17 to maintain a force away from the feeding seat 15.

[0033] Therefore, in combination Figure 1 and Figure 4 it can be seen that the principle of the above feeding is that the action of the spring 19 enables the clamping portion 17 to have a force to move to the right. At this time, when moving to the right, the clamping portion 17 clamps the strip material. When the upper arm driving member 11 rotates and the convex block 14 touches the first bearing 12, it makes the upper end of the feeding force arm 10 tend to move to the right, thereby making the lower end of the feeding force arm 10 tend to move to the left. The second bearing 13 is connected to the side surface of the linkage disk 18. Therefore, the second bearing 13 will push the linkage disk 18 to the left, that is, make the clamping portion 17 move to the left. At this time, the clamping portion 17 loosens the strip material, and the spring 19 is compressed. When the convex block 14 rotates away, the action of the spring 19 enables the clamping portion 17 to move to the right again, clamping the strip material and advancing again to achieve the purpose of feeding.

[0034] Specifically, as Figure 5As shown, the pivot point of the feeding force arm 10 on the frame 1 serves as the rotation fulcrum A. The straight-line distance between the first bearing 12 and the rotation fulcrum A is set as L1, and the straight-line distance between the second bearing 13 and the rotation fulcrum A is set as L2. Then L1 is greater than L2. The principle of this setting is that the raised block 14 acts on the first bearing 12, and the torque of the raised block 14 on the first bearing 12 is the same as the torque of the second bearing 13 on the linkage disk 18. Since L1 is greater than L2, according to the torque calculation formula M = F * L, this structure can make the relatively small acting force of the raised block 14 on the first bearing 12 generate a relatively large acting force of the second bearing 13 on the linkage disk 18, which helps to better push the linkage disk 18 to move.

[0035] And it can be seen from Figure 1 that from the first bearing 12 to the rotation fulcrum A, and from the second bearing 13 to the rotation fulcrum A, the arm width dimension of the feeding force arm 10 gradually increases. That is, making the position width of the middle section of the feeding force arm 10 larger will result in better force bearing.

[0036] One end of the rotating shaft 2 is connected with a driving wheel 20. The driving wheel 20 is connected with a first driving wheel 21 through a belt. The first driving wheel 21 is coaxially connected with a second driving wheel 22. The second driving wheel 22 is connected with a driving motor 23 through a belt. Therefore, the driving motor 23 drives the second driving wheel 22 to rotate, and finally drives the rotating shaft 2 to rotate. The driving motor 23 is fixed inside the frame 1. From the front view direction, the second driving wheel 22 is located at the lower center part of the frame 1. That is, making the driving motor 23 and the second driving wheel 22 be set at the lower center part of the frame 1 as much as possible helps to enhance the center of gravity of the whole structure being at the center and ensure stability as much as possible.

[0037] A balance auxiliary wheel 24 is arranged on the side of the rotating shaft 2 opposite to the driving wheel 20. The virtual connection line between the centers of the balance auxiliary wheel 24 and the driving wheel 20 coincides with the central axis of the rotating shaft 2. The function here is to balance the gravity of the driving wheel 20 on the other side of the rotating shaft 2 by setting the balance auxiliary wheel 24, so that the overall force on the rotating shaft 2 is relatively balanced, which helps the rotating pressure wheel 25 to drive the stamping block 7 to press down more stably.

[0038] The design principle of this double-output bead chain machine is:

[0039] By extending the rotating shaft 2, two or more rotating pressing wheels 25 are horizontally arranged side by side on the rotating shaft 2. The structural dimensions of each rotating pressing wheel 25 are the same, and the rotating pressing wheel 25 abuts against the pressing block 7 located below to control the movement of the pressing block 7. The lower end of the pressing block 7 is connected to the upper pressing module 8; the layout distance of two or more rotating pressing wheels 25 along the length direction of the rotating shaft 2 on the rotating shaft 2 corresponds to the length distance of the upper pressing module 8; the difference from the traditional bead chain machine is that there is only one rotating pressing wheel 25 on the traditional rotating shaft 2. Also in this technical solution, the number of rotating pressing wheels 25 is two or more. In this embodiment, the number of rotating pressing wheels 25 is two, because in order to meet the installation of the number of rotating pressing wheels 25, it is achieved by lengthening the rotating shaft 2; and below each rotating pressing wheel 25, it correspondingly abuts against the pressing block 7, and the pressing block 7 is synchronously driven by two rotating pressing wheels 25 to control the downward pressing of the upper pressing module 8; the upper pressing module 8 and the bearing module 9 are used in a matching manner; the upper pressing module 8 is the upper die of the installation mold, and the bearing module 9 is the lower die of the installation mold; the strip is conveyed between the upper die and the lower die of the mold, and when the upper die of the mold presses on the lower die, the bead is punched out; the traditional one only has one rotating pressing wheel 25, and only one bead can be punched out. In this embodiment, by increasing the rotating pressing wheel 25, the length distance of the upper pressing module 8 can also be increased, that is, there can be a pressing die cavity for two beads between the upper die and the lower die of the mold, so as to achieve the purpose of pressing out two beads when the rotating shaft 2 rotates one circle. "The layout distance of two or more rotating pressing wheels 25 along the length direction of the rotating shaft 2 on the rotating shaft 2 corresponds to the length distance of the upper pressing module 8", the understanding here is that if the length distance of the upper pressing module 8 corresponding to one rotating pressing wheel 25 is 10 cm, there is only one pressing die cavity for the bead of the mold installed in the upper pressing module 8 and the bearing module 9; then the length distance of the upper pressing module 8 corresponding to two rotating pressing wheels 25 is 20 cm, and there are only two pressing die cavities for the beads of the mold installed in the upper pressing module 8 and the bearing module 9, and so on. By adding the rotating pressing wheel 25, the effect of doubling the output can be achieved.

[0040] A forearm driving member 11 is installed on the rotating shaft 2, and a protruding block 14 is provided on the forearm driving member 11. The protruding block 14 abuts against the upper end of the feeding force arm 10 to drive the feeding force arm 10 to swing; by increasing the distance between the outermost end of the lateral protrusion of the protruding block 14 and the side surface of the forearm driving member 11, the purpose of increasing the swing stroke of the feeding force arm 10 is achieved; the protruding block 14 will push the upper end of the feeding force arm 10 upward to the side, so that the lower end of the feeding force arm 10 swings in the opposite direction; and the greater the distance between the outermost end of the lateral protrusion of the protruding block 14 and the side surface of the forearm driving member 11, the greater the distance that the lower end of the feeding force arm 10 swings in the opposite direction. This design is to increase the swing stroke of the feeding force arm 10.

[0041] The lower end of the feeding force arm 10 is connected to the progressive feeding component. The swinging stroke of the feeding force arm 10 directly controls the conveying length of the strip in the progressive feeding component. By setting the lateral protruding height dimension of the protruding block 14, the conveying length of the strip is made to correspond to the length distance of the stamping die. By increasing the swinging stroke of the feeding force arm 10, the purpose is to increase the feeding amount of the strip, and the increased length corresponds to the length distance of the upper pressing module 8 (the length distance of the upper pressing module 8 corresponds to the number arrangement of the rotating pressing wheels 2525).

[0042] By installing bearings at the upper and lower ends of the feeding force arm 10, the connection between the upper end of the feeding force arm 10 and the protruding block 14, and the connection between the lower end of the feeding force arm 10 and the progressive feeding component are rolling frictions, so as to reduce wear and improve the smooth operation.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
