Description

Technical Field

[0001] This utility model relates to the field of spinning, specifically to an auxiliary yarn feeding and stabilizing yarn insertion mechanism for a yarn feeding frame of a plying machine. Background Technology

[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. Yarn is divided into short fiber yarn and continuous filament yarn. In yarn production, a plying machine is often used. A plying machine is a device that combines multiple strands of yarn into one strand. During plying, a yarn feeding frame is needed to support the yarn tubes of each strand.

[0003] The auxiliary yarn feeding and stabilizing yarn insertion mechanism of the current yarn feeding frame of the twisting machine, as described in patent announcement number CN218711146U, includes a column, a pressure plate, a first damping pad, a first nut, a limiting thread, a first wear-resistant pad, a second nut, a second damping pad, a second wear-resistant pad, and an elastic spindle. The pressure plate is provided on one side of the middle of the column, and the first damping pad is provided in the middle of one side of the pressure plate. The first nut is provided on the side of the first damping pad. The limiting threads are provided on both sides of the middle of the column, and the second nut is provided around the periphery of the limiting thread on one side of the column. The first wear-resistant pad is provided in the middle of the inner side of the pressure plate.

[0004] Regarding the aforementioned technologies, the inventors believe that the fixed maximum outer diameter of the elastic spindle makes it impossible for the elastic spindle to effectively limit the insertion of yarn tubes with larger inner diameters, while it is more difficult to insert yarn tubes with smaller inner diameters. As a result, the entire yarn insertion mechanism is unable to meet the insertion and removal needs of yarn tubes with different inner diameters, resulting in poor applicability of the entire yarn insertion mechanism. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary yarn feeding and stable yarn insertion mechanism for the yarn feeding frame of a plywood machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary yarn feeding and stabilizing yarn insertion mechanism for a yarn feeding frame of a plywood machine, comprising:

[0008] A limiting mechanism includes a column, an upper rotating ring rotatably connected to the outer side of the column, a support plate sleeved on the outer side of the column, a lower rotating ring fixedly connected to the top of the support plate, and multiple support rods arranged in a circular array between the upper and lower rotating rings. Each set of support rods is rotatably connected to both ends of a traction rod. Each set of traction rods on the upper side is rotatably connected to the upper rotating ring, and each set of support plates on the lower side is rotatably connected to the lower rotating ring.

[0009] An adjustment mechanism is provided, comprising an upper connecting ring rotatably connected to the bottom of the support plate, a spring fixedly connected to the bottom of the upper connecting ring, a lower connecting ring fixedly connected to the bottom of the spring, and an internal threaded ring rotatably connected to the bottom of the lower connecting ring, the internal threaded ring being threadedly connected to the column.

[0010] As a further embodiment of this utility model: a cone cap is fixedly connected to the top of the column, and the bottom diameter of the cone cap is larger than the diameter of the upper rotating ring.

[0011] As a further embodiment of this utility model, multiple anti-slip grooves are evenly provided on the outer side of the support rod.

[0012] As a further embodiment of this utility model: a guide groove is provided on the outer side of the column, and a guide block adapted to the guide groove is fixedly connected to the inner wall of the upper connecting ring.

[0013] As a further embodiment of this utility model: the outer side of the internal threaded ring is fixedly connected with multiple protrusions in a ring array.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] With the above-mentioned structure, this utility model, through the mutual cooperation of the internal threaded ring, spring, internal threaded ring and lower connecting ring, enables the lower connecting ring, upper connecting ring and support plate to move up and down when the internal threaded ring rotates. When the support plate moves up and down, it can drive the lower rotating ring to move up and down. When the lower rotating ring moves up and down, it can pull each set of support rods to rotate relative to or opposite to each other through the lower set of traction rods, thereby adjusting the initial spacing of each set of support rods, which facilitates the insertion and removal of yarn tubes with different inner diameters, thereby improving the applicability of the entire yarn insertion mechanism.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-4 A yarn feeding and stabilizing mechanism for a yarn feeding frame of a plywood machine includes a limiting mechanism 1. The limiting mechanism 1 includes a column 101, with an upper rotating ring 102 rotatably connected to the outer side of the column 101. The column 101 is configured to support the upper rotating ring 102. A conical cap 108 is fixedly connected to the top of the column 101. The bottom diameter of the conical cap 108 is larger than the diameter of the upper rotating ring 102, facilitating yarn tube insertion. A support plate 107 is sleeved on the outer side of the column 101, serving to support and limit the yarn tube.

[0024] A lower rotating ring 103 is fixedly connected to the top of the support plate 107. Multiple support rods 105 are arranged in a circular array between the upper rotating ring 102 and the lower rotating ring 103. The support rods 105 are positioned to abut against the inner wall of the yarn tube, thereby limiting the movement of the yarn tube. Multiple anti-slip grooves 106 are evenly distributed on the outer side of the support rods 105. The anti-slip grooves 106 increase the friction between the support rods 105 and the inner wall of the yarn tube, thereby reducing the probability of the yarn tube rotating relative to the support rods 105.

[0025] Each set of support rods 105 has a traction rod 104 rotatably connected to both ends. Each set of traction rods 104 on the upper side is rotatably connected to the upper rotating ring 102, and each set of support plates 107 on the lower side is rotatably connected to the lower rotating ring 103. The lower rotating ring 103 is set to drive each set of traction rods 104 on the lower side to rotate during up and down movement, thereby pulling each set of support rods 105 to move relative to or away from each other.

[0026] Adjustment mechanism 2 includes an upper connecting ring 201 rotatably connected to the bottom of support plate 107. A guide groove 205 is provided on the outer side of the column 101. A guide block 207, adapted to the guide groove 205, is fixedly connected to the inner wall of the upper connecting ring 201. The guide groove 205 and guide block 207 are used to guide the upper connecting ring 201. A spring 202 is fixedly connected to the bottom of the upper connecting ring 201. The spring 202 is used to push the upper connecting ring 201 and support plate 107 upwards using its elasticity.

[0027] A lower connecting ring 203 is fixedly connected to the bottom of the spring 202. An internally threaded ring 204 is rotatably connected to the bottom of the lower connecting ring 203. The internally threaded ring 204 is threadedly connected to the column 101. The internally threaded ring 204 is designed to drive the lower connecting ring 203 to move up and down during rotation. Multiple protrusions 206 are fixedly connected in a ring array on the outer side of the internally threaded ring 204. The protrusions 206 are designed to prevent slippage when the internally threaded ring 204 is rotated.

[0028] In use, the yarn tube is inserted from the top of the cone cap 108, causing the yarn tube to push the upper sets of traction rods 104 to rotate, which in turn pulls the sets of support rods 105 to move relative to each other. When the sets of support rods 105 move relative to each other, the lower rotating ring 103, support plate 107, and upper connecting ring 201 move downwards due to the traction of the lower sets of traction rods 104, compressing the spring 202 until the sets of support rods 105 are inserted into the yarn tube, so that the sets of support rods 105 abut against the inner wall of the yarn tube. When insertion is required... When using yarn tubes of other inner diameters, the internal threaded ring 204 can be rotated, causing the internal threaded ring 204 to drive the lower connecting ring 203, the upper connecting ring 201, and the support plate 107 to move up and down. When the support plate 107 moves up and down, it can drive the lower rotating ring 103 to move up and down. When the lower rotating ring 103 moves up and down, it can pull the support rods 105 to rotate relative to each other or in opposite directions through the lower traction rods 104, thereby adjusting the distance between the support rods 105 to facilitate the insertion and removal of yarn tubes with different inner diameters.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
