Description

Technical Field

[0001] This utility model belongs to the field of fabric roll pulling technology, specifically a non-woven fabric roll pulling shaft and a shaft threading device. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is a nonwoven material composed of oriented or randomly arranged fibers. It has the appearance and properties of cloth, but does not require the spinning and weaving process. The main raw material of nonwoven fabric is usually polypropylene (PP). It is made by directly using polymer chips, short fibers or filaments to form a web through airflow or mechanical means, and then strengthening it through hydroentangling, needle punching or thermal rolling, and finally finishing to form a nonwoven fabric.

[0003] Nonwoven fabrics possess numerous superior properties, including moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. They also have a cotton-like feel, and compared to cotton fabrics, nonwoven bags are easier to shape and cheaper to manufacture. These properties have led to the widespread application of nonwoven fabrics in various fields. For example, in the medical and health field, nonwoven fabrics can be used to make surgical gowns, masks, bed sheets, and diapers; in home decoration, they can be used for wallpaper, tablecloths, and bed sheets; and in industry, they can be used as filter materials, insulation materials, and packaging linings.

[0004] After being packaged and slit, non-woven fabric rolls need to undergo processes such as unrolling (threading), fabric tail processing, labeling, packaging, weighing, and stacking before finally being stored in the warehouse. Traditionally, after the fabric is output from the slitting machine and received by the fabric receiving cart, the fabric rolls need to be manually unrolled, and new paper rolls need to be inserted into the unrolled fabric rolls before being put back into the slitting machine. Manual unrolling and threading of the rolls is time-consuming, labor-intensive, inefficient, and unsafe. Utility Model Content

[0005] To address the problems of time-consuming, labor-intensive, inefficient, and unsafe manual shaft pulling and threading, this utility model provides a nonwoven fabric roll shaft pulling and threading device.

[0006] This utility model is achieved through the following technical solution:

[0007] A nonwoven fabric roll pulling shaft and threading device includes a pulling shaft mechanism and a fabric receiving frame that can be moved back and forth and adjusted.

[0008] A V-shaped fabric roll frame is rotatably mounted on the fabric splicing machine frame. A through-shaft frame that can position and place the paper roll and a swing motor that drives the fabric roll frame to flip are positioned on the fabric splicing machine frame. Limiting frames that can limit the fabric roll are installed at both ends of the fabric roll frame.

[0009] The shaft pulling mechanism includes a shaft pulling frame and several support rollers rotatably mounted on the shaft pulling frame and capable of rolling support for the fabric roll. At one end of the shaft pulling frame near the fabric receiving frame, a pressure roller capable of pressing the fabric roll is rotatably mounted via a pressure roller frame. The shaft pulling frame is equipped with a support roller drive motor that drives the rotation of the support rollers and a pressure roller drive cylinder that drives the flipping of the pressure roller frame.

[0010] A further improvement of this utility model is that the limiting frame has an L-shaped plate structure.

[0011] A further improvement of this utility model is that the limiting frame can be adjusted left and right and positioned on the fabric roll frame.

[0012] A further improvement of this utility model is that a first limiting block and a second limiting block, which can support and limit the flipping of the fabric roll frame, are respectively installed on the front and rear sides of the fabric receiving machine frame.

[0013] Further improvements to this utility model include a paper roll support plate installed at the bottom of the through-shaft frame, which can position and support the paper roll; and vertical lifting cylinders installed at both ends of the through-shaft frame, with lifting seats connected to the telescopic ends of the lifting cylinders.

[0014] Further improvements to this invention include: four rollers are provided at the four corners of the bottom of the fabric splicing frame, with two rollers on the left and right sides connected by a drive shaft; a mobile motor that drives the rotation of the drive shaft is positioned and installed on the fabric splicing frame; and two slide rails that can guide and support the rolling of the rollers.

[0015] A further improvement of this utility model is that a guide leg is connected and installed at the bottom of the fabric receiving frame, and the bottom of the guide leg has a slot that cooperates with the slide rail limit locking.

[0016] A further improvement of this utility model is that the shaft pulling mechanism is equipped with two vertical lifting guide rails, and the shaft pulling frame is equipped with a slider that slides and guides the lifting guide rails; the shaft pulling mechanism is equipped with a lifting power mechanism, which is connected to the shaft pulling frame through the shaft pulling frame connecting rod.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] In use, the swing motor drives the fabric roll frame to flip forward (front side flips downward), which facilitates the support of the fabric roll (with fabric roll shaft) cut by the slitting machine. The swing motor drives the fabric roll frame back to the center position (opening directly upward), and the fabric roll is supported on the upper side of the V-shaped fabric roll frame. The two ends of the fabric roll are limited to the left and right by two limit frames, and the fabric roll shaft extends out of the limit frames. Control the fabric receiving frame to move backward, so that the support roller is in contact with the underside of the extended fabric roll shaft. Control the pressure roller drive cylinder to move, drive the pressure roller frame to flip, and realize the pressure roller pressing the fabric roll shaft. Control the support roller drive motor to drive the three support rollers near one end of the fabric receiving frame to rotate, so that the fabric roll shaft can be easily pulled out. Then, the swing motor is controlled to drive the fabric roll frame to flip backward (the rear side flips downward), causing the fabric roll to move backward into the subsequent process. Simultaneously, the fabric splicing frame is controlled to continue moving backward, aligning the pull-out frame and the threading frame. A new paper roll is placed into the threading frame, and then the support roller drive motor is controlled to rotate in the opposite direction, causing the fabric roll shaft on the support roller to insert into the paper roll on the threading frame. The paper roll with the fabric roll shaft is then removed. Next, the pressure roller drive cylinder is controlled to drive the pressure roller to flip upward to open and reset, and the fabric splicing frame moves forward to reset. This completes the pull-out and threading operations for the non-woven fabric roll. The overall structure is simple, easy to use, and highly efficient in pull-out and threading operations for non-woven fabric rolls, effectively saving manpower and improving operational safety.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1-5 As shown, this utility model discloses a non-woven fabric roll pulling and threading device, including a pulling mechanism 300 and a fabric receiving frame 200 that can be moved back and forth and adjusted; the pulling mechanism 300 is arranged on the left and / or right side of the fabric receiving frame 200.

[0028] A V-shaped fabric roll frame 209 is rotatably mounted on the fabric splicing frame 200 via two bearing seats 211. The fabric roll frame 209 is arranged left and right, and the center line of the bearing seats 211 is in the left and right direction. A through-shaft frame 205 (located in front of the fabric roll frame 209) for positioning and placing the paper roll is positioned on the fabric splicing frame 200, and a swing motor 212 for driving the flipping of the fabric roll frame 209 is installed. A first drive arm 213 is connected to the output shaft of the swing motor 212. A second drive arm 214 is rotatably connected to the end of the first drive arm 213 away from the swing motor 212. The end of the second drive arm 214 away from the first drive arm 213 is rotatably connected to the lower front side of the fabric roll frame 209. Limiting frames 210 for limiting the fabric roll are installed at both ends of the fabric roll frame 209 (left and right).

[0029] The shaft pulling mechanism 300 includes a shaft pulling frame 301 in the left-right direction and several support rollers 302 (the axis of the support rollers 302 is in the front-back direction) rotatably mounted on the shaft pulling frame 301 and capable of rolling support for the fabric roll. A pressure roller frame 306 is rotatably mounted on one end of the shaft pulling frame 301 near the fabric receiving frame 200. A pressure roller 303 (the axis of the pressure roller 303 is in the front-back direction) capable of pressing the fabric roll is rotatably mounted on the upper end of the pressure roller frame 306. A support roller drive motor 304 and a pressure roller drive cylinder 305 are mounted on the shaft pulling frame 301. The support roller drive motor 304 is synchronously connected to the three support rollers 302 near the fabric receiving frame 200 via chain drive (it can synchronously drive the three support rollers 302 to rotate). A connecting rod is rotatably connected to the telescopic end of the pressure roller drive cylinder 305. The end of the connecting rod away from the pressure roller drive cylinder 305 is rotatably connected to the lower end of the pressure roller frame 306.

[0030] In use, the swing motor 212 drives the fabric roll frame 209 to flip forward (front side flips downward) to support the fabric roll (with fabric roll shaft) cut by the slitting machine. The swing motor 212 drives the fabric roll frame 209 back to the center position (opening directly upward). The fabric roll is supported on the upper side of the V-shaped fabric roll frame 209. The two ends of the fabric roll are limited left and right by two limit frames 210, and the fabric roll shaft extends out of the limit frames 210. The fabric receiving frame 200 is controlled to move backward so that the support roller 302 is in contact with the lower side of the extended fabric roll shaft. The pressure roller drive cylinder 305 is controlled to move, driving the pressure roller frame 306 to flip, so that the pressure roller 303 presses the fabric roll shaft. The support roller drive motor 304 is controlled to drive the three support rollers 302 near one end of the fabric receiving frame 200 to rotate, so that the fabric roll shaft can be easily pulled out. Then, the swing motor 212 drives the fabric roll frame 209 to flip backward (rear side flips downward), causing the fabric roll to move backward into the subsequent process. At the same time, the fabric splicing frame 200 continues to move backward, aligning the puller frame 301 with the threading frame 205. A new paper roll is placed into the threading frame 205. Then, the support roller drive motor 304 is controlled to rotate in the opposite direction, driving the fabric roll shaft on the support roller 302 to insert into the paper roll on the threading frame 205, removing the paper roll with the fabric roll shaft. Then, the pressure roller drive cylinder 305 is controlled to drive the pressure roller 303 to flip upward to open and reset, and the fabric splicing frame 200 moves forward to reset. This completes the puller and threading operation of the nonwoven fabric roll. The overall structure is simple and easy to use, and it is highly efficient in the puller and threading operation of nonwoven fabric rolls, effectively saving manpower and improving operational safety.

[0031] To ensure the reliability and accuracy of the front and rear positioning of the fabric roll and to prevent the fabric roll from shifting, the support roller 302 and the pressure roller 303 have an hourglass-shaped structure that is thinner in the middle and thicker at both ends, which effectively increases the support and pressing area of ​​the fabric roll and effectively prevents slippage.

[0032] The fabric receiving frame 200 has rollers 202 rotatably mounted at its four corners. Two rollers 202 facing each other are connected by a drive shaft 203, with rollers 202 fixedly mounted at both ends of the drive shaft 203. The drive shaft 203 is rotatably mounted to the fabric receiving frame 200 via bearing seats. A moving motor 204 is positioned on the fabric receiving frame 200. Corresponding sprockets are mounted on the output end of the moving motor 204 and on the drive shaft 203, and the two sprockets are connected by a chain drive. The device also includes two forward and backward sliding rails 100 that provide rolling guidance and support for the rollers 202. By driving the rollers 202 to rotate via the moving motor 204, the rollers 202 can be guided forward and backward on the sliding rails 100, ensuring precise and reliable adjustment of the forward and backward movement of the fabric receiving frame 200.

[0033] Furthermore, four guide legs 201 (at the four corners, corresponding to the front and rear of the rollers 202) are connected and installed at the bottom of the fabric receiving frame 200. The bottom of the guide legs 201 has a slot that engages with the slide rail 100 for limiting and locking. By engaging with the slide rail 100 for limiting and locking through the slot at the lower end of the guide legs 201, the precision and reliability of the front and rear movement adjustment of the fabric receiving frame 200 are achieved.

[0034] The pull-out mechanism 300 is equipped with two vertical lifting guide rails 307, and the pull-out frame 301 is equipped with a slider that slides and guides the lifting guide rails 307. The pull-out mechanism 300 contains a lifting power mechanism, which is connected to the pull-out frame 301 via a pull-out frame connecting rod 308. The lifting power mechanism can be a motor-driven ring chain, which is connected to the pull-out frame connecting rod 308. This allows for precise and reliable adjustment of the pull-out frame 301, enabling flexible application to pull-out of fabric rolls of different thicknesses, achieving flexibility and versatility in pull-out and threading, and making it more flexible and convenient to use.

[0035] The limiting frame 210 has an L-shaped plate structure with its vertical section at the rear, which effectively stops the fabric roll shaft (with fabric roll) to prevent the fabric roll from rolling off and ensure operational safety.

[0036] Furthermore, to ensure the structural strength of the limiting frame 210, it is provided with several reinforcing ribs. The reinforcing ribs are located in the middle of the limiting frame 210 and are also L-shaped, which effectively strengthens the structure of the limiting frame 210.

[0037] Furthermore, the bottom of the horizontal section of the limiting frame 210 is bent with a horizontal connecting plate. The connecting plate has elongated holes in the left and right directions. The bottom of the fabric roll frame 209 has a T-slot. A nut is installed in the T-slot. The bolt passes through the elongated hole and the T-slot and is screwed to the nut. The left and right adjustment of the limiting frame 210 can be achieved by loosening the bolt, which can effectively realize the application of limiting fabric rolls of different widths and has a wider range of applications.

[0038] The fabric receiving frame 200 is equipped with two (symmetrical) first limiting blocks 215 at the front to support and limit the forward flipping of the fabric roll frame 209, and two (symmetrical) second limiting blocks 216 at the rear to support and limit the backward flipping of the fabric roll frame 209. The first limiting blocks 215 and the second limiting blocks 216 limit the flipping angle of the fabric roll frame 209, thereby ensuring the reliability and safety of the flipping of the fabric roll frame 209.

[0039] The paper roll support plate 206, which can position and support the paper roll, is installed at the bottom of the paper roll threading frame 205. Vertical lifting cylinders 207 are installed at both ends of the paper roll threading frame 205, and lifting seats 208 are connected to the telescopic ends of the lifting cylinders 207. After the new paper roll is threaded through the paper roll, the lifting cylinders 207 are extended, and the lifting seats 208 lift the paper roll threaded through the paper roll, which can realize the convenient transfer of the paper roll (threaded through the paper roll).

[0040] In use, the nonwoven fabric roll puller and threading device uses a swing motor 212 to drive the fabric roll frame 209 to flip forward (front side flips downward) to support the fabric roll (with fabric roll shaft) cut by the slitting machine. The swing motor 212 drives the fabric roll frame 209 back to the center position (opening directly upward). The fabric roll is supported on the upper side of the V-shaped fabric roll frame 209. The two ends of the fabric roll are limited left and right by two limit frames 210, and the fabric roll shaft extends out of the limit frames 210. The fabric receiving frame 200 is controlled to move backward so that the support roller 302 is in contact with the underside of the extended fabric roll shaft. The pressure roller drive cylinder 305 is controlled to move, driving the pressure roller frame 306 to flip, so that the pressure roller 303 presses the fabric roll shaft. The support roller drive motor 304 is controlled to drive the three support rollers 302 near one end of the fabric receiving frame 200 to rotate, thereby realizing the convenient pull-out of the fabric roll shaft. Then, the swing motor 212 drives the fabric roll frame 209 to flip backward (rear side flips downward), causing the fabric roll to move backward into the subsequent process. At the same time, the fabric splicing frame 200 continues to move backward, aligning the puller frame 301 with the threading frame 205. A new paper roll is placed into the threading frame 205. Then, the support roller drive motor 304 is controlled to rotate in the opposite direction, driving the fabric roll shaft on the support roller 302 to insert into the paper roll on the threading frame 205, removing the paper roll with the fabric roll shaft. Then, the pressure roller drive cylinder 305 is controlled to drive the pressure roller 303 to flip upward to open and reset, and the fabric splicing frame 200 moves forward to reset. This completes the puller and threading operation of the nonwoven fabric roll. The overall structure is simple and easy to use, and it is highly efficient in the puller and threading operation of nonwoven fabric rolls, effectively saving manpower and improving operational safety.
