Description

Technical Field

[0001] The utility model belongs to the technical field of sewing bobbin winders, is mainly used for winding sewing bobbin threads, and specifically relates to a bobbin winding machine with an adjustable cycloid function. Background Art

[0002] Taking the general sewing bobbin thread as an example, the traditional sewing bobbin thread is wound by flattening the wool thread against the edge. However, if the wool thread tension is too high, it will cause the thread to get stuck, affecting the sewing effect. Therefore, adding a controllable swing mechanism can effectively reduce the thread jamming problem caused by excessive thread tension. In this way, the wool thread tension can be appropriately increased while ensuring that the wool thread is not stuck, thereby increasing the winding amount of a single bobbin and reducing the frequency of replacing the bobbin. This article describes a winding machine with an adjustable cycloidal function that optimizes the more common structure. The traditional winding machine consists of a storage device, a knob assembly, and a motor assembly. The wool thread is placed on the storage device and enters the knob assembly to adjust the thread tension, and then the thread is pulled by the motor assembly and wound around the bobbin. The bobbin made with this structure will have the following shortcomings:

[0003] The amount of thread wound on the bobbin is small. Since the thread tension cannot be too large, in order to ensure that the wool threads do not get stuck with each other during the winding process, the winding tension must be reduced. This inevitably reduces the amount of thread wound on the bobbin. The difference in the structure described in this patent is that a connecting rod device is added, which can increase the winding tension and increase the winding amount without ensuring that the wool threads are not stuck.

[0004] The amount of thread wound on the bobbin is small. Since the thread tension cannot be too large, the thread tension should be reduced during the winding process to ensure that the wool threads do not get stuck with each other. Summary of the invention

[0005] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a winding machine with an adjustable cycloid function. The machine mainly solves the problem of reduced bobbin winding amount due to the inability to increase the line tension. Therefore, combined with the traditional method, a winding machine with an adjustable cycloid function described in this article is structurally optimized and adjusted, which reduces the frequency of replacing the bobbin and increases the winding amount.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The utility model discloses a winding machine with an adjustable cycloid function, comprising: a motor assembly, a gear transmission device, and a connecting rod device.

[0008] The motor assembly is used to pull the wool thread to be wound on the bobbin for use, and drives the swing lever through the driving gear transmission device;

[0009] The gear transmission device is installed on the motor assembly;

[0010] The connecting rod device is installed on the motor assembly and connected with the gear transmission device.

[0011] The motor assembly includes: a motor, a motor bracket, a driving gear, a bobbin shaft, and a bobbin.

[0013] The motor is mounted on a motor bracket;

[0014] The bobbin is installed on the bobbin shaft.

[0015] The gear transmission device includes: a transmission shaft, a driven gear, a shaft seat 1, a bevel gear, a shaft seat 2, a cam, and a guide frame.

[0016] The driven gear and bevel gear are mounted on the transmission shaft, and the transmission shaft is mounted on the shaft seat 1;

[0017] The bevel gear is mounted on the cam, and the cam is mounted on the second shaft seat;

[0018] The axle seat 1 and the axle seat 2 are installed on the guide frame;

[0019] The guide frame is installed on the motor bracket, and is mainly used to ensure that the first shaft seat and the second shaft seat remain vertical and their centers are in the same plane.

[0020] The connecting rod device comprises: a connecting rod 1, a connecting rod 2, a guide rail and a swing lever.

[0021] The connecting rod 1 is installed on the cam, and can adjust the cycloid amplitude to adapt to different multiples of bobbins by connecting different hole positions;

[0022] The connecting rod 2 is installed on the connecting rod 1;

[0023] The swing lever is connected with the second connecting rod and is fixedly mounted on the guide rail to ensure that the swing direction is always perpendicular to the wool thread.

[0024] This patent uses a connecting rod device to move the sewing thread back and forth, obtains power from the motor assembly through a gear transmission device and maintains a fixed transmission ratio with the motor assembly. The connecting rod device can be adapted to different multiples of bobbins by adjusting different connection hole positions.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0033] In order to further understand the content, characteristics and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0034] The invention discloses a winding machine with an adjustable cycloid function, comprising: a motor assembly 1, a gear transmission device 2, and a connecting rod device 3.

[0035] The motor assembly 1 includes: a motor 4, a motor bracket 5, a driving gear 6, a bobbin shaft 7, and a bobbin 8.

[0036] The bobbin shaft 7 and the driving gear 6 are mounted on the motor 4, which provides power to drive the bobbin 8 to rotate and perform winding work;

[0037] The motor 4 is mounted on a motor bracket 5;

[0038] The bobbin 8 is mounted on the bobbin shaft 7 .

[0039] The gear transmission device 2 includes: a transmission shaft 9, a driven gear 10, a shaft seat 11, a bevel gear 12, a shaft seat 2 13, a cam 14, and a guide frame 15.

[0040] The driven gear 10 and the bevel gear 12 are mounted on the transmission shaft 9, and the transmission shaft 9 is mounted on the shaft seat 11;

[0041] The bevel gear 12 is mounted on the cam 14, and the cam 14 is mounted on the shaft seat 13;

[0042] The shaft seat 11 and the shaft seat 2 13 are installed on the guide frame 15;

[0043] The guide frame 15 is installed on the motor bracket 5, and is mainly used to ensure that the shaft seat 1 and the shaft seat 2 remain vertical and their centers are in the same plane.

[0044] The connecting rod device 3 includes: a connecting rod 16 , a connecting rod 2 17 , a guide rail 18 , and a swing lever 19 .

[0045] The connecting rod 16 is installed on the cam 14, and can adjust the cycloid amplitude to adapt to different multiples of the bobbin core 8 by connecting different hole positions;

[0046] The connecting rod 2 17 is installed on the connecting rod 1 16;

[0047] The swing lever 19 is connected to the second connecting rod 17 and fixedly mounted on the guide rail 18 to ensure that the swing direction is always perpendicular to the wool yarn.

[0048] Working process:

[0049] The sewing bottom thread passes through the thread hole of the swing lever 19 and is wound around the bobbin 8. After the winding is started, the motor 4 drives the bobbin 8 installed on the bobbin shaft 7 to rotate. At the same time, the driving gear 6 installed on the motor 4 will rotate through the driven gear 10 and the transmission shaft 9 to the bevel gear 12. The two bevel gears 12 cooperate to complete the transmission reversing. The cam 14 rotates through the connecting rod 16 and the connecting rod 2 17 to drive the swing lever 19 to reciprocate perpendicular to the rotation direction of the bobbin 8. The sewing bottom thread in the thread hole of the swing lever 19 swings back and forth accordingly. After the sewing bottom thread on the bobbin 8 is wound, it has a swinging pattern, and the sewing bottom thread will not be stuck due to the sewing bottom thread being squeezed between the two threads when the thread tension is increased.
