Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment manufacturing, and relates to the improvement of an automatic winding machine, in particular to a bobbin processing and conveying device and an automatic winding machine. Background Art

[0002] In existing tray-type automatic winders, bobbins are fed from a vibrating bowl in the yarn storage. The bobbins are then positioned by a bobbin release mechanism and a funnel before being inserted onto the tray below. Improvements to the bobbin release mechanism have significantly increased the insertion speed. The bobbin handling and conveying system on automatic winders is typically equipped with two sets of spinning-in mechanisms.

[0003] In the bobbin processing assembly of the existing automatic winding machine, the trays for conveying bobbins are driven by a round belt and a flat belt. When there are many trays in the bobbin processing assembly, the round belts will often fall off. Once the round belts fall off, the entire machine will stop, and it is not easy for the operator to handle it.

[0004] The specific working process of the bobbin processing component of the existing automatic winding machine: see Figure 1 、 Figure 2 The bobbins that have been unwound by the single spindle are first pulled out by the tube pulling device 5, and then inserted by the tube inserting device 4 and preferentially enter the first spinning device 7. The bobbins that are full in the first spinning device or have failed to be spun by the first spinning device enter the second spinning device, and the bobbins that have been spun successfully enter the single spindle. When there are many bobbins in the bobbin processing assembly, the friction force on the original round belt 3 is large, causing the original round belt 3 to stretch greatly. Since the main drive pulley 2 of the round belt is the source of the transmission round belt, the section from the original round belt 3 led from the left side of the main drive pulley 2 to the original driven pulley 10 closest to it is the original round belt easy to fall off part 11, where the tension is relatively low. At the same time, the original round belt 3 turns back 180 degrees at the original driven pulley 10, and the original round belt 3 is easy to fall off from the original driven pulley 10. In order to solve the problem of the original round belt 3 falling off, the applicant has tried to use an original round belt 3 with an aramid core. This round belt is relatively expensive and still cannot completely solve the problem of the round belt 3 falling off. Sometimes the original round belt 3 is damaged, which seriously affects the production efficiency of the automatic winder.

[0005] The urgent technical challenge is how to design a bobbin handling and conveying device and an automatic winding machine that rationalizes the transmission mechanism and optimizes the round belt transmission route, thereby solving the problem of round belt shedding while simplifying the round belt splicing process and reducing maintenance costs. Summary of the Invention

[0006] In order to solve the above-mentioned problems and shortcomings of the prior art, the present invention provides a bobbin processing and conveying device and an automatic winding machine, so that the transmission mechanism in the bobbin processing and conveying device is reasonably designed. By optimizing the round belt transmission route, the problem of round belt falling off can be solved, and the round belt joint work can be simplified, thereby reducing maintenance costs.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A bobbin processing and conveying device comprises a bobbin processing assembly, wherein the bobbin processing assembly comprises a round belt, a round belt drive motor, a round belt main drive pulley and a passive pulley, and is characterized in that the round belt comprises a first round belt and a second round belt, the bobbin processing assembly further comprises a round belt sub-drive motor and a round belt sub-drive pulley, all of the passive pulleys are divided into two groups, the first group of passive pulleys and the round belt main drive pulley are surrounded by the first round belt, the second group of passive pulleys and the round belt sub-drive pulley are surrounded by the second round belt, the round belt drive motor drives the round belt main drive pulley to drive the first round belt and the first group of passive pulleys to rotate, and the round belt sub-drive motor drives the round belt sub-drive pulley to drive the second round belt and the second group of passive pulleys to rotate.

[0009] Improvements to the above technical solution: the overall profile of the first round belt is "L"-shaped, with the middle turning angle ranging from 80° to 110°; the overall profile of the second round belt is "I"-shaped.

[0010] Further improvement to the above technical solution: the length of the first round belt is greater than the length of the second round belt.

[0011] Further improvement to the above technical solution: the number of the passive pulleys in the first group is greater than the number of the passive pulleys in the second group.

[0012] Further improvement to the above technical solution: the first round belt and the second round belt do not use a belt tensioning device, but adopt a natural tensioning method.

[0013] Further improvement to the above technical solution: the bobbin processing assembly further includes a flat belt and a transmission motor thereof.

[0014] An automatic winding machine includes a winding machine spindle, and is characterized in that the winding machine spindle includes the above-mentioned bobbin processing and conveying device.

[0015] The advantages and positive effects of the present invention are:

[0016] 1. This invention replaces the original single long round belt with two shorter round belts and adds a round belt auxiliary drive motor. Ordinary round belts can be used for the round belts, which are relatively low in cost. Because the two round belts are shorter and experience less friction, their elongation is also reduced. The round belts extending from both sides of the main drive pulley are both longer, with a right-angled transition in the middle, optimizing the round belt transmission path and completely eliminating the problem of round belt shedding.

[0017] 2. The present invention eliminates the belt tensioning device and adopts a natural tensioning method, which simplifies the structure and reduces the manufacturing cost;

[0018] 3. The present invention replaces the original single long round belt with two shorter round belts, thereby optimizing the round belt transmission route, simplifying the round belt joint work, and reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0024] See also Figure 3An embodiment of a bobbin processing and conveying device according to the present invention includes a bobbin processing assembly 13, which includes a round belt, a round belt drive motor 1, a round belt main drive pulley 2, and a driven pulley. The round belt includes a first round belt 3-1 and a second round belt 3-2. The bobbin processing assembly 13 also includes a round belt sub-drive motor 12 and a round belt sub-drive pulley. All the driven pulleys are divided into two groups. The first group of driven pulleys and the round belt main drive pulley 2 are surrounded by the first round belt 3-1, while the second group of driven pulleys and the round belt sub-drive pulleys are surrounded by the second round belt 3-2. The round belt drive motor 1 drives the round belt main drive pulley 2 to rotate the first round belt 3-1 and the first group of driven pulleys. The round belt sub-drive motor 12 drives the round belt sub-drive pulley to rotate the second round belt and the second group of driven pulleys.

[0025] Furthermore, the overall profile of the first round belt 3-1 is in an "L" shape, with an intermediate turning angle ranging from 80° to 110° (preferably 90°); the overall profile of the second round belt 3-2 is in an "I" shape.

[0026] from Figure 3 It can be seen that the present patent application optimizes the transmission route of the round belt: 1. The first driven pulley 14 passing through the middle turning point of the first round belt 3-1 is connected to the first driven pulley 14. Figure 2 Compared with the original first passive pulley 10 in the prior art, the distance from the round belt main drive pulley 2 is farther, the length of the first round belt 3-1 in this section is increased, and the turning angle of the first round belt 3-1 at the passive pulley 14 is basically a right angle, which is better than Figure 2 The prior art shown reduces the angle by 90°. Secondly, the length of each round belt is reduced, which reduces the friction experienced by each round belt (first round belt 3-1 and second round belt 3-2), and thus reduces belt elongation. By implementing these technical measures, the problem of round belts falling off is completely eliminated.

[0027] Furthermore, the length of the first round belt 3 - 1 is greater than the length of the second round belt 3 - 2 .

[0028] Furthermore, the number of the passive pulleys in the first group is greater than the number of the passive pulleys in the second group.

[0029] Furthermore, the first round belt 3-1 and the second round belt 3-2 do not use a belt tensioning device, but adopt a natural tensioning method, which can reduce the production cost.

[0030] In addition, the bobbin processing assembly of the present invention further comprises a flat belt 6 and a transmission motor thereof. The flat belt 6 and the transmission motor thereof can be made of existing technology, so they are not described in detail.

[0031] See also Figure 3 An embodiment of an automatic winding machine of the present invention includes a winding machine spindle 15, and the winding machine spindle 15 includes the bobbin processing and conveying device of the above embodiment.

[0032] See also Figure 1 The bobbin processing assembly 13 of the automatic winding machine of the present invention further comprises a tube inserting device 4, a tube pulling device 5, a flat belt 6, a first threading device 7, a second threading device 8, and a tray 9. The above-mentioned components can be made of existing technologies, so they are not described in detail.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
