Description

Technical Field

[0001] The utility model relates to the technical field of spring preparation, in particular to a multi-layer wave spring winding device. Background Art

[0002] When processing multi-layer wave springs, wave spring machines (referred to as wave spring machines) are often used for winding and forming. However, since the raw materials for wave spring processing are in the form of rolls, after the raw materials are used up, it is necessary to replace the raw material rolls and pull the raw materials to the feeding mechanism, which makes loading more inconvenient. For example:

[0003] Chinese patent publication number CN206604978U discloses a wave spring washer forming machine that uses a design that clamps two material trays at the same time. Workers can prepare replacement material trays without stopping the machine. When the material in the tray is used up, the main bracket is rotated and the spare material tray is rotated to continue using it. This greatly shortens the machine's downtime and effectively improves production efficiency.

[0004] In the above technical solution, the design of clamping two material trays at the same time and replacing the material trays by rotation requires manual pulling of the end of the raw material before it can enter the feeding mechanism, which makes it impossible to replace it quickly.

[0032] Example 1

[0033] like Figure 1-6 As shown, the utility model proposes a multi-layer wave spring winding device, including a bracket 1, a support plate 7, a limit rod 3, a housing 5 and a drive assembly 4;

[0034] like Figure 1-3 As shown, the support plates 7 are installed on the inner side of the bracket 1, and there are at least two of them. The upper part of each support plate 7 is provided with a rotating seat 2 for placing the raw material coil in the spring processing state; the limiting rod 3 is installed in the middle of the rotating seat 2;

[0035] The two sides of the bracket 1 and the side surface of one end of the housing 5 are provided with a plurality of through holes arranged at equal distances; bolts are passed through the through holes to mount the housing 5 on the side surface of the bracket 1 in a state where the height can be adjusted; when in use, the housing 5 is connected to the feeding mechanism, and the connection method is not limited to direct connection, for example, the housing 5 and the feeding mechanism can be connected through a pipe;

[0036] The number of the driving components 4 is the same as the number of the rotating seats 2. One end of the driving components 4 is installed on the inner side of the shell 5, and the other end passes through the shell 5 and is installed on the outer side of the shell 5 for fixing the end of the raw material wound on the raw material roll and pulling and conveying it.

[0037] In this embodiment, two raw material rolls are placed on the rotating seat 2 respectively, and one end of the raw material is passed through the drive component 4 and placed on the inner side of the shell 5. When the processing is in progress, one drive component 4 is running, and when one raw material roll is used up, the other drive component 4 is running, so that the two raw material rolls are used alternately, which is more convenient for replacing and pulling the raw materials.

[0038] Example 2

[0039] like Figure 5-6 As shown, the utility model proposes a multi-layer wave spring winding device. Compared with the first embodiment, the difference between this embodiment and the first embodiment is that;

[0040] The inner size of the shell 5 gradually decreases from one end of the shell 5 to the other end of the shell 5 along the height direction of the upper bracket 1; the inner side of the shell 5 has a guide plate 6 installed in conjunction with the drive component 4, and the shape of the guide plate 6 is adapted to the shape of the shell 5. When the raw material moves from the inside of the shell 5, it is used to guide the end of the raw material so that the raw materials moved out of the two drive components 4 can move to the same position. Among them, in the processing state, the smaller end of the shell 5 is connected to the feeding mechanism in a manner not limited to direct connection, and the raw materials on the two rotating seats 2 are directly transported to the feeding mechanism without traction.

[0041] Example 3

[0042] like Figure 2-3 As shown, the present invention proposes an automatic water treatment disinfection device. Compared with the first embodiment, this embodiment also describes in detail the specific structure of the rotating seat 2;

[0043] The rotating base 2 includes a bull's eye wheel 21 mounted on the upper end surface of the support plate 7; a mounting plate 22 rotatably connected to the top of the bull's eye wheel 21; and a retaining ring 23 mounted on the upper edge of the mounting plate 22 for limiting the position of the raw material roll placed on the mounting plate 22;

[0044] In an optional embodiment, at least one annular groove is provided at the bottom end of the mounting disk 22. When the bull's eye wheel 21 and the mounting disk 22 are in a mounted state, the top of the bull's eye wheel 21 is accommodated in the annular groove of the mounting disk 22, wherein the annular groove is a moving path. When in use, the ball at the top of the bull's eye wheel 21 rolls in the annular groove to rotate the mounting disk 22, making it more convenient to unwind the raw material roll.

[0045] In an optional embodiment, a boss is provided downwardly in the middle of the lower end surface of the mounting plate 22; a through hole is provided in the middle of the upper end surface of the mounting plate 22 that passes through the boss; a bottom section of the limiting rod 3 is rectangular, and the bottom of the limiting rod 3 is inserted into the inner side of the through hole of the mounting plate 22, and the rectangular matching connection of the through hole limiting rod 3 of the mounting plate 22 is formed, wherein the lower size of the limiting rod 3 is smaller than the upper part of the limiting rod 3, and the lower shape of the limiting rod 3 is non-circular, mainly to avoid the limit rod 3 from rotating when installed on the mounting plate 22, and the boss is used to increase the thickness of the mounting plate 22 to avoid the limit rod 3 from falling off easily due to the shallow through hole of the mounting plate 22.

[0046] Example 4

[0047] like Figure 4 As shown, the utility model proposes a multi-layer wave spring winding device. Compared with the third embodiment, this embodiment also describes in detail the specific structure of the retaining ring 23;

[0048] The baffle ring 23 includes a baffle I 231 connected to the edge of the upper end surface of the mounting disk 22; a baffle II 232 clamped at the end of the baffle I 231 and placed on the upper end surface of the mounting disk 22, wherein both the baffle I 231 and the baffle II 232 are semicircular rings. When placing the raw material roll, the baffle II 232 is removed so that the upper end surface of the mounting disk 22 has half of the blockage. After installation, it is used to adjust the position of the raw material roll on the mounting disk 22 to limit the raw material roll when it is not connected to the limit rod 3.

[0049] Example 5

[0050] like Figure 5-6 As shown, the utility model proposes a multi-layer wave spring winding device. Compared with the first embodiment, this embodiment further describes in detail the specific structure of the drive assembly 4; the drive assembly 4 is provided with two groups; the structures of the two groups of drive assemblies 4 are exactly the same;

[0051] The driving assembly 4 includes two rollers 41 that cooperate with each other and are rotatably installed in the shell 5. The gap between the two rollers 41 is adapted to the size of the raw material; one of the rollers 41 passes through the side wall of the shell 5 to transmit and connect to the driver 42; wherein, the driver 42 is a motor, and the driver 42 is selected from but not limited to being installed on the outer side of the shell 5, and the output shaft of the driver 42 is connected to the rotating shaft of the roller 41 extending out of the shell 5; the two rollers 41 are in a horizontal rolling arrangement with the same axis as above and below, and are used to cooperate with the rotating base 2 stacked up and down.

[0052] In this embodiment, the driver 42 drives one roller 41 to rotate. Due to the friction between the raw material and the roller 41 and the cooperation of the other roller 41 , one end of the raw material is transported.

[0053] In summary, when the present invention is in use, the two limit rods 3 are respectively inserted into the middle of the raw material roll, and a raw material roll is placed above the rotating seat 2, the limit rod 3 is inserted into the middle of the rotating seat 2, and then the ends of the raw materials of the two raw materials rolls are respectively moved toward a driving component 4, the ends of the raw materials of the two raw materials rolls are inserted between the two rollers 41 and the rollers 41 are driven to rotate by a driver 42, so that the raw materials on one raw material roll are moved toward the feeding mechanism. During the movement, the raw material roll drives the mounting plate 22 to rotate on the bull's eye wheel 21 due to friction. At the same time, due to the structural shape of the shell 5, the raw materials are accurately transported to the feeding port of the feeding mechanism. After one raw material roll is used up, the other driver 42 is started, and the raw materials on the other raw material roll are moved to the feeding mechanism with the assistance of the two rollers 41, and the used raw material roll roller can be disassembled and replaced without interfering with the production of the multi-layer wave spring, so that the production of the multi-layer wave spring has an uninterrupted effect, thereby improving production efficiency.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
