Description

Technical Field

[0001] This utility model relates to the technical field of dental floss production equipment, and in particular to an automatic winding mechanism. Background Technology

[0002] In daily life, people use toothpicks to clean food residue left between their teeth. However, using toothpicks can damage the gums. Using dental floss to clean teeth has become a new trend. Existing dental floss is usually coiled and packaged in a bag for consumers to use.

However, existing winding mechanisms drive all winding units through a single drive mechanism, which is a one-to-many mechanism. This can lead to insufficient precision and uneven winding lengths. Furthermore, the transmission mechanism of existing winding machines is relatively complex, which makes it difficult to ensure synchronization and guarantee the quality of winding dental floss in the same batch.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0051] Example 1:

[0052] like Figure 1-4As shown in the embodiment of this application, an automatic winding mechanism is disclosed, which is specifically installed on an automatic winding machine to complete the winding of dental floss. The automatic winding mechanism drives two sets of winding units to wind the floss through a motor, which facilitates the control of winding accuracy and improves product quality. At the same time, a cam mechanism is also set inside to realize back and forth swing, so as to further improve the winding quality, that is, to ensure uniform winding length and high accuracy (the wire length is controlled within 0.5m).

[0053] like Figure 1 As shown, the specific structure of this application includes:

[0054] The spindle housing 1 has a cavity 101 inside. Specifically, the spindle housing 1 has an opening at the top and the cavity is provided inside. In use, the interior is equipped with corresponding components to cooperate in realizing the winding function.

[0055] The transmission mechanism 2 is installed on one side of the spindle housing 1, specifically, from... Figure 4 As can be seen, multiple transmission mechanisms 2 are installed on the left side of the spindle housing 1, and are spaced apart along the length of the spindle housing 1.

[0056] Cam assembly 3 is installed at the output end of the transmission mechanism 2 and is located inside the main shaft housing 1. Cam assembly 3 is the core component of the transmission and facilitates the forward and backward movement of the subsequent swing shaft.

[0057] The winding positioning assembly 4 is installed at the end of the cam assembly 3, and the winding positioning assembly 4 is located on the other side of the spindle housing 1. Figure 4 As can be seen from the image, the winding positioning component 4 is located on the right side of the main spindle housing 1, and a wire core is subsequently installed thereon. Together with other components, it can realize the winding rotation. Specifically, the winding positioning component 4 in this application can be one or two. When there are two, one of them is connected to the cam assembly 3, and the remaining one is connected to the auxiliary drive shaft.

[0058] The swing shaft assembly 5 cooperates with the cam assembly 3, and one end of the swing shaft assembly 5 passes through the spindle housing 1. Specifically, the part of the swing shaft assembly 5 that passes through the spindle housing 1 is located above the winding positioning assembly 4, that is, it is also located on the right side of the spindle housing 1. The back-and-forth movement of the swing shaft assembly 5 allows the wire to move back and forth along the winding positioning assembly 4, thereby ensuring that the winding is more uniform and thus improving the quality of the winding.

[0059] When winding, the loops should not remain in one place, as this will result in too many loops in certain areas, causing uneven winding. Therefore, the winding direction should be oscillating back and forth to improve the winding quality. Specifically, for example... Figure 3 As shown, the cam assembly 3 includes:

[0060] The rotating shaft 301 is connected to one end of the transmission mechanism 2, and at the other end is connected to a winding positioning component 4, which facilitates rotation.

[0061] Cam 302 is mounted on the rotating shaft 301, and a curved groove 303 is provided on the outer side of cam 302. The curved groove 303 is the power source of the subsequent swing component 5. That is, by rotating cam 302, the curved groove 303 is rotated, thereby the swing component 5 moves along the axial direction of rotating shaft 301.

[0062] The swing shaft assembly 5 includes:

[0063] A cam follower bearing 501 is disposed inside the curved groove 303. The end of the cam follower bearing 501 is located inside the curved groove 303 and cooperates with it, which facilitates the forward and backward movement of the cam follower bearing 501.

[0064] The swing connection unit 502 is installed on the cam follower bearing 501. This connection unit facilitates the subsequent back-and-forth movement of the swing shaft 503.

[0065] A swing shaft 503 is installed on the swing connection unit 502, and one end of the swing shaft 503 passes through one side of the spindle housing 1. Similarly, the part of the swing shaft 503 that passes through the spindle housing 1 is located on the right side of the spindle housing 1.

[0066] In this application, the motion power of the swing shaft 503 comes from the cam follower bearing 501. In order to ensure the stability of the movement of the swing shaft 503, the swing shaft assembly 5 also includes at least two guide shafts 504. The guide shafts 504 are installed in parallel at intervals inside the accommodating cavity 101, and the guide shafts 504 are located on both sides of the rotating shaft 301. The swing connecting unit 502 is installed on the guide shaft 504, so that the swing connecting unit 502 can move stably along the guide shaft 504, thereby realizing the back-and-forth movement of the swing shaft 503.

[0067] To ensure the stability of the movement of the swing connection unit 502, such as Figure 2 As shown, the swing connection unit 502 includes:

[0068] Linear bearing components 505 are installed one-to-one on the guide shaft 504, and the linear bearing components 505 can ensure that the overall structure moves stably along the guide shaft 504.

[0069] The swing connecting plate 506 is installed on the linear bearing component 505;

[0070] The stroke adjustment block 507 is installed on the swing connecting plate 506, and the swing shaft 503 is installed on the stroke adjustment block 507, which helps to improve the stability of the swing shaft 503 movement.

[0071] To further explain the structure of this application, a cam assembly 3 and a swing shaft assembly 5 are added to realize the back-and-forth swing of the swing shaft 503. The winding positioning assembly 4 is connected to the rotating shaft 301, which enables rotation. Combined with the swing shaft assembly 5, the back-and-forth swing can be realized while winding is completed, thereby ensuring the quality of winding.

[0072] This application enables the synchronous movement of two winding positioning components 4 through the transmission mechanism 2, thereby improving efficiency. Specifically, the transmission mechanism 2 includes:

[0073] The main drive component 201 is installed on one side of the spindle housing 1 and is connected to the cam assembly 3. In subsequent use, the main drive component 201 is directly connected to the drive component, such as a motor.

[0074] The auxiliary transmission component 202 is installed on one side of the main spindle housing 1, and the auxiliary transmission component 202 and the main transmission component 201 are connected by a belt. The belt can achieve synchronous rotation. In order to facilitate precise control, a counter can be installed at the end of the auxiliary transmission component 202 to know the actual number of revolutions.

[0075] The auxiliary drive shaft 203 is connected to the auxiliary drive component 202. That is, the auxiliary drive shaft 203 rotates under the drive of the auxiliary drive component 202, thereby driving a winding positioning assembly to rotate.

[0076] There are two winding positioning components 4. One winding positioning component 4 is connected to the cam assembly 3, and the other winding positioning component 4 is connected to the auxiliary drive shaft 203. Specifically, the two winding positioning components 4 can work synchronously and cooperate with a swing shaft assembly 5 to complete the winding work. The winding positioning component includes components such as bearing seat, positioning shaft and positioning sleeve, which are existing mechanisms and will not be described in detail here.

[0077] The swing shaft assembly 5 is equipped with corresponding components to cooperate with the swing. In order to ensure the stability of the movement of this type of device, a limiting shaft 6 is provided on the outside of the main spindle housing 1 in this application. The limiting shaft 6 and the winding positioning assembly 4 are located on the same side of the main spindle housing 1.

[0078] Further explanation is provided regarding this application:

[0079] The connections between the various components are based on the existing structure and will not be described in detail here.

[0080] This application is applied to an automatic winding machine and makes improvements to the transmission mechanism. Specifically, it adds a swing shaft assembly 5, in which the swing shaft 503 can move back and forth, thereby realizing back and forth swinging during winding and improving the winding effect.

[0081] In this application, a transmission mechanism, a cam assembly, two winding positioning assemblies, a swing shaft assembly, and a guide shaft are combined to form a swing winding mechanism. During operation, the drive assembly is activated to enable the transmission mechanism 2 to work, that is, the main transmission component 201, the secondary transmission component 202, and the secondary transmission shaft 203 begin to work. At this time, the cam assembly 3 connected to the main transmission component 201 begins to work, that is, the cam 302 rotates, thereby realizing the movement of the groove 303, which in turn drives the swing shaft assembly 5 to move back and forth, thereby driving the swing shaft 503 to move forward and backward. Meanwhile, the winding positioning assembly 4 can drive the wire to rotate to complete the winding, and at the same time, combined with the swing shaft 503, it can realize swing winding, thereby improving the winding quality.
