Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a tail yarn removal device for textile machinery production. Background Technology

[0002] Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., were ancient textile machines that relied on human power to weave cloth. Textile machines are the full name of the tools used to process raw materials such as thread, silk, and hemp into silk threads and then weave them into cloth.

[0003] Currently, existing yarn removal devices for textile machinery production require adjustments to clean the yarn tails outside the rollers due to variations in roller diameter and length. This process is time-consuming and labor-intensive. Furthermore, because all rollers are cleaned simultaneously, some rollers may have their yarn tails completely removed but are still being transported slowly, while others may have their yarn tails partially removed before being transported out of the device. This results in inconsistent and unreliable yarn tail removal. Therefore, we propose a new yarn removal device for textile machinery production. Utility Model Content

[0004] The main objective of this invention is to provide a tail yarn removal device for textile machinery production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A yarn tail removal device for textile machinery production includes a support base and a conveyor belt and a transport belt installed on top of the support base, with the conveyor belt and transport belt connected end-to-end. A removal belt for winding up the yarn tail is provided above the transport belt, and the transport belt and removal belt are parallel to each other.

[0007] Multiple sets of telescopic rods are installed at equal intervals on both sides of the conveyor belt, and a self-locking motor is installed at the telescopic end of the telescopic rod. A connecting seat is connected to the output shaft of the self-locking motor. The connecting seat limits the yarn roller with the tail yarn wound on it through a placement plate connected to its front end.

[0008] Preferably, the conveyor belt has multiple sets of drive rollers connected inside by bearings, and one set of drive rollers is driven by a No. 1 motor installed outside the conveyor belt.

[0009] Preferably, the interior of the cleaning belt is connected to multiple sets of connecting rollers via bearings, and the exterior of the multiple sets of connecting rollers is fitted with protrusions for hooking the tail yarn. One set of connecting rollers is driven by a second motor installed on one side of the cleaning belt.

[0010] Preferably, the connecting seats on both sides of the conveyor belt correspond to each other.

[0011] Preferably, the placement plate has an arc-shaped cross-section, and the placement plate is connected to a support plate installed at the front end of the connecting seat by a spring, with a pressure sensor connected to one end of the spring.

[0012] Preferably, the slider installed at the rear end of the placement plate is slidably connected to the groove formed at the front end of the connecting seat.

[0013] Preferably, both the self-locking motor and the pressure sensor are electrically connected to a power source mounted on top of the conveyor belt via wires.

[0014] Preferably, the top of the cleaning belt is provided with a scraper for scraping off the tail yarn, and the front end of the scraper is connected to a collection box installed on one side of the support base through a pipe, and a fan is installed on the pipe between the scraper and the collection box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, by setting protrusions on the outside of the connecting roller, the stability of the tail yarn gripping can be improved;

[0017] Secondly, by setting telescopic rods with self-locking motors on both sides of the conveyor belt and connecting a placement plate to the output shaft of the self-locking motor, it is possible not only to clean yarn rollers of different sizes as needed, but also to prevent the yarn rollers from interfering with each other, thereby improving the applicability and stability of the device.

[0018] Third, by setting a pressure sensor on the support plate and a spring between the pressure sensor and the placement plate, it is possible not only to detect whether the tail yarn has been cleaned, but also to maintain the stability of the pressure between the yarn roller and the cleaning belt.

[0026] Reference Figure 1-4 As shown, a yarn tail removal device for textile production includes a support base 1 and a conveyor belt 2 and a transport belt 3 installed on top of the support base 1. The conveyor belt 2 and the transport belt 3 are connected end to end. A removal belt 4 for winding up the yarn tail is provided above the transport belt 3, and the transport belt 3 and the removal belt 4 are parallel to each other.

[0027] Multiple sets of telescopic rods 6 are installed at equal intervals on both sides of the conveyor belt 3, and a self-locking motor 7 is installed at the telescopic end of the telescopic rod 6. A connecting seat 8 is connected to the output shaft of the self-locking motor 7. The connecting seat 8 limits the yarn roller with the tail yarn wound on it through the placement plate 11 connected to its front end.

[0028] Reference Figure 2 As shown, the conveyor belt 3 has multiple sets of drive rollers 5 connected inside by bearings, and one set of drive rollers 5 is driven by a No. 1 motor installed outside the conveyor belt 3.

[0029] Reference Figure 2 As shown, the interior of the cleaning belt 4 is connected to multiple sets of connecting rollers 9 via bearings, and the exterior of the multiple sets of connecting rollers 9 is fitted with protrusions 10 for hooking the tail yarn. One set of connecting rollers 9 is driven by a No. 2 motor installed on one side of the cleaning belt 4.

[0030] Reference Figure 2 The connecting seats 8 on both sides of the conveyor belt 3 correspond to each other.

[0031] Reference Figure 3 and Figure 4 As shown, the cross-section of the placement plate 11 is arc-shaped, and the placement plate 11 is connected to the support plate 12 installed at the front end of the connecting seat 8 by a spring, and a pressure sensor 13 is connected to one end of the spring.

[0032] Reference Figure 4The slider installed at the rear end of the placement plate 11 is slidably connected to the groove opened at the front end of the connecting seat 8.

[0033] Reference Figure 2 and Figure 4 The self-locking motor 7 and the pressure sensor 13 are both electrically connected to a power source mounted on top of the conveyor belt 3 via wires.

[0034] Reference Figure 1 The top of the cleaning belt 4 is equipped with a scraper for scraping off the tail yarn, and the front end of the scraper is connected to a collection box installed on one side of the support 1 through a pipe, and a fan is installed on the pipe between the scraper and the collection box.

[0035] In use, the yarn roller wound with the tail yarn is transported towards the conveyor belt 3 via the conveyor belt 2 at the top of the support seat 1. Simultaneously, the telescopic rods 6 on both sides of the conveyor belt 3 drive the self-locking motor 7 to retract, causing the self-locking motor 7 and the connecting seat 8 connected to the output shaft of the self-locking motor 7 to be fixed downwards together. When the connecting seat 8 contacts the outside of the transmission roller 5, the self-locking motor 7 is energized, driving the connecting seat 8 and the placement plate 11 at the front end of the connecting seat 8 to rotate. When the opening of the placement plate 11 faces the front end of the conveyor belt 3, it stops. At this time, the opening of the placement plate 11 faces forward, and the yarn roller moves towards the placement plate 11 under the transport of the conveyor belt 3, so that both ends of the yarn roller enter the middle position of the placement plate 11 along the opening. At this time, the yarn roller is confined between the two connecting seats 8. The yarn roller then presses against the placement plate 11, causing the placement plate 11 to press backward against the support plate 12, compressing the spring connected between the support plate 12 and the placement plate 11. The pressure at one end of the spring... When the value detected by sensor 13 increases, it indicates that the yarn roller has entered the placement plate 11. Then, the self-locking motor 7 is energized and rotated, causing the opening of the placement plate 11 to face upward. At this time, the yarn roller squeezes the placement plate 11 by its own weight and the weight of the tail yarn. Therefore, the pressure value detected by pressure sensor 13 is the weight of the yarn roller and the tail yarn. By comparing it with the set value, the weight of the tail yarn is obtained. At the same time, the telescopic rod 6 at the bottom of the self-locking motor 7 is extended, pushing the self-locking motor 7 with the yarn roller upward, so that the yarn roller contacts the connecting roller 9 outside the cleaning belt 4. At this time, the tail yarn outside the yarn roller contacts the protrusion 10 outside the connecting roller 9, thereby winding up the tail yarn wrapped outside the yarn roller. Then, the scraper peels off the wound tail yarn. The peeled tail yarn is sent into the collection box for storage by the fan. When the value detected by pressure sensor 13 reaches the set range, the yarn roller is put back on the conveyor belt 3 according to the above principle, completing the removal of the tail yarn outside the yarn roller.
