Description

Technical Field

[0001] This application relates to the field of automatic tape feeding technology, and in particular to an automatic tape feeding device for large-package webbing cutting. Background Technology

[0002] In the production, processing, and subsequent cutting and sewing of webbing, the webbing feeding equipment is one of the core supporting equipment. Especially in the large-scale processing of large packaging webbing, it is often necessary to feed multiple webbings simultaneously and with unified traction. Existing webbing feeding equipment is prone to webbing misalignment in the feeding channel, further aggravating the entanglement problem. Summary of the Invention

[0003] The purpose of this application is to provide an automatic tape feeding device for large-package cutting of webbing to solve the technical problem that "webbing is prone to misalignment in the feeding channel of the tape feeding device".

[0004] This application provides an automatic tape feeding device for large-package webbing cutting, which adopts the following technical solution: The device includes a support frame. Multiple spool support rods are fixed on both sides of the support frame. These spool support rods are used to install winding spools, enabling simultaneous installation of multiple spools. A webbing limiting rod is provided on the support frame, located directly above the spool support rods. This limiting rod is used to change the direction of webbing movement and to initially limit the webbing during the initial feeding stage. A webbing buffer assembly is installed on the support frame, at the same height as the webbing limiting rod, to prevent the webbing from being wound. The belt is conveyed in a straight line. The webbing buffer assembly is used to counteract the swaying during webbing release, ensuring stable webbing tension. A webbing traction assembly is installed on the support frame to provide power for webbing release and prevent reverse displacement of the webbing. A webbing limiting assembly is installed on the support frame to ensure that the webbing is arranged in a straight line, preventing the webbing from shifting or tangling. The webbing buffer assembly includes a damping rod with a flipping plate fixed on it. A limiting channel is formed between the flipping plates. A webbing flipping rod is fixed to the end of the flipping plate away from the damping rod. The webbing is installed in an S-shape on the damping rod and the webbing flipping rod. The webbing is wound in an S-shape around the damping rod and the webbing flipping rod, using the S-shape to increase the contact friction between the webbing and the rod, thus counteracting the swaying.

[0005] Furthermore, a spool separator is installed on the spool support rod to separate adjacent spools and prevent them from rubbing against each other when rotating; the spool support rod is provided with a sliding groove and multiple positioning holes, the spool separator can slide along the sliding groove and be locked in position through the positioning holes, which facilitates the adjustment of the spool spacing according to the wire feeding requirements.

[0006] Furthermore, the coil isolator includes a positioning ring and a positioning plate. The positioning plate is fixed to one side of the positioning ring for easy manual rotation of the positioning ring. The positioning ring has a positioning groove inside, in which a positioning spring, a positioning pin, and an external threaded ring are sequentially installed. The external threaded ring locks the positioning spring and positioning pin in the positioning groove, ensuring structural stability. The end of the positioning pin furthest from the positioning spring is spherical, and the pin passes through the external threaded ring, causing the spherical portion to protrude. When the positioning pin is engaged in the positioning hole, the coil isolator is locked on the upper coil support rod. Rotating the positioning plate can move the positioning pin into the sliding groove, enabling quick disassembly and installation of the coil isolator and improving coil clamping efficiency.

[0007] Furthermore, the webbing buffer assembly has two implementation structures, both of which can achieve stable webbing tension: Structure 1: The webbing buffer assembly includes a damping component fixed on a support frame. A damping rod is installed on the damping component, and a flipping plate is fixed on the damping rod. A limiting channel is formed between the flipping plates to limit the webbing. A webbing flipping rod is fixed to the end of the flipping plate away from the damping rod. The damping component includes a support cylinder fixed on the support frame and a torsion spring installed in the support cylinder. The damping rod is sleeved in the torsion spring. One end of the torsion spring is connected to the support cylinder, and the other end is connected to the damping rod. The elastic damping effect of the torsion spring can adaptively adjust the rotational resistance of the damping rod according to the swaying of the webbing, further stabilizing the webbing tension.

[0008] Structure 2: Includes a support member fixed to a support frame and a damping rod fixed to the support member. A damping cylinder is sleeved on the damping rod, and a torsion spring is provided between the damping rod and the damping cylinder to provide elastic damping for the rotation of the damping cylinder. Flip plates are fixed at both ends of the damping cylinder, forming a limiting channel between the flip plates. A webbing flipping rod is fixed on the flip plates, and the webbing is also wound in an S-shape around the damping cylinder and the webbing flipping rod here. A partition is provided between the damping cylinders, and the partition is fixed to the damping rod to prevent adjacent damping cylinders from affecting each other when rotating, ensuring the independence of multi-tissue belt anti-buffering operation.

[0009] Furthermore, the webbing traction assembly includes a drive roller and a limiting roller mounted on a support frame. The drive roller is driven by a drive motor to provide power for webbing feed. The support frame is equipped with a sliding block and a displacement telescopic component. The displacement telescopic component is used to control the vertical displacement of the sliding block, thereby adjusting the distance between the limiting roller and the drive roller. A ratchet is mounted on the sliding block, and the limiting roller is mounted on the ratchet. The limiting roller is made of rubber to increase the friction with the webbing. When the limiting roller is in contact with the drive roller, it can clamp the webbing. Under the unidirectional rotation limiting action of the ratchet, it prevents the webbing from shifting in the opposite direction and ensures the uniqueness of the feed direction.

[0010] Furthermore, a control center and a control switch are installed on the support frame. The control center, control switch, displacement telescopic component and drive motor are electrically connected. The control switch can control the extension and retraction of the displacement telescopic component through the control center, so as to realize convenient adjustment of the clamping tightness of the limit roller and the drive roller, and adapt to the traction needs of webbing of different thicknesses and materials.

[0011] Furthermore, the webbing limiting assembly includes a support plate fixed on a support frame. A pair of parallel feed rods are fixed on the support plate. Multiple dividing plates are installed on the feed rods, dividing the space between the two feed rods into multiple independent feed channels. Each feed channel corresponds to a limiting channel of the webbing buffer assembly, allowing multiple webbings to follow their own paths and achieve a straight-line arrangement, preventing the webbing from shifting and tangling. An upper eccentric wheel and a lower eccentric wheel are installed on the feed rod. A flip spring is installed between the lower eccentric wheel and the feed rod. The elastic force of the flip spring can control the lower eccentric wheel and the upper eccentric wheel to fit tightly together. The fitting structure of the eccentric wheels guides the webbing and simultaneously achieves unidirectional displacement limiting of the webbing, further improving the orderliness of the feed.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. During the webbing unloading process, the webbing winding spool is installed on the spool support rod. After the webbing passes around the webbing limiting rod, it is wound in an S-shape around the webbing buffer assembly. The webbing then passes through the webbing traction assembly, which pulls the webbing through friction. The webbing then passes through the limiting assembly, causing the webbing to be arranged in a straight array. The limiting assembly corresponds to the webbing buffer assembly, thereby effectively preventing the webbing from shifting in the unloading channel of the webbing unloading equipment and causing the webbing to become entangled.

[0013] 2. During the unwinding process, the ribbon is buffered by the webbing buffer assembly, which effectively winds the ribbon in an S-shape onto the damping rod and the webbing flipping rod. The S-shape increases the contact friction between the ribbon and the rod, counteracting the buffering sway and further stabilizing the ribbon tension, thus ensuring stable ribbon output.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be described in further detail below.

[0017] Reference Figure 1An automatic webbing feeding device for large-scale packaging includes a support frame 1. Multiple spool support rods 2 are fixed on both sides of the support frame 1. The spool support rods 2 are used to mount winding spools. A webbing limiting rod 3 is provided on the support frame 1, located directly above the spool support rods 2. The webbing limiting rod 3 is used to change the direction of webbing movement. A webbing buffer assembly 5 is installed on the support frame 1, at the same height as the webbing limiting rod 3, to ensure the webbing is conveyed in a straight line. A webbing feeding device is also installed on the support frame 1. The webbing traction component 6 provides power for webbing release and prevents webbing from shifting in the opposite direction. A webbing limiting component 7 is installed on the support frame 1 to keep the webbing in a straight line and prevent the webbing from shifting and getting tangled. The webbing buffer component 5 includes a damping rod 52, on which a flipping plate 53 is fixed. A limiting channel is formed between the flipping plates 53. A webbing flipping rod 54 is fixed to the end of the flipping plate 53 away from the damping rod 52. The webbing is installed in an S-shape on the damping rod 52 and the webbing flipping rod 54.

[0018] During the webbing unloading process, the webbing winding spool is installed on the spool support rod 2. After the webbing passes around the webbing limiting rod 3, it is wound in an S-shape around the webbing buffer assembly 5. The webbing then passes through the webbing traction assembly 6, which pulls the webbing through friction. The webbing then passes through the limiting assembly 7, causing the webbing to be arranged in a straight line array. The limiting assembly 7 corresponds to the webbing buffer assembly 5, thereby effectively preventing the webbing from shifting in the unloading channel of the webbing unloading equipment and causing the webbing to become entangled.

[0019] During installation, the webbing passes from the lower side of the damping rod 52 between the damping rod 52 and the webbing flipping rod 54, and then to the upper side of the webbing flipping rod 54, so that the webbing is installed on the webbing buffer assembly 5 in an S-shape. When the webbing traction assembly 6 pulls the webbing, after being buffered by the webbing buffer assembly 5, the webbing can be effectively wound in an S-shape and installed on the damping rod and the webbing flipping rod. The S-shaped winding increases the contact friction between the webbing and the rod, counteracts the buffer sway, and further stabilizes the webbing tension, thereby ensuring stable output of the webbing.

[0020] Reference Figure 1 , Figure 2 A reel separator 21 is installed on the reel support rod 2. A sliding groove 22 and multiple positioning holes 23 are provided on the reel support rod 2. When installing the reel onto the reel support rod 2, first install one reel separator 21 onto the reel support rod 2, then install the reel. After the reel is installed, install the second reel separator 21 onto the reel support rod 2. The two reel separators 21 are parallel to each other, clamping the reel in the middle, further preventing positional shift during reel unloading, thereby improving the stability of the reel conveying.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The coil isolator 21 includes a positioning ring 24 and a positioning plate 25. The positioning plate 25 is fixed to one side of the positioning ring 24. The positioning ring 24 has a positioning groove 26 inside. A positioning spring 27 is installed in the positioning groove 26. A positioning pin 28 is slidably installed in the positioning groove 26. An external threaded ring 29 is installed in the positioning groove 26. The external threaded ring 29 is used to lock the positioning spring 27 and the positioning pin 28 in the positioning groove 26. The end of the positioning pin 28 away from the positioning spring 27 has a spherical structure. The positioning pin 28 passes through the external threaded ring 29 and protrudes from the spherical part. When the positioning pin 28 is stuck in the positioning hole 23, the coil position is locked on the coil support rod 2. Rotating the positioning plate 25 causes the positioning pin 28 to move to the sliding groove 22, realizing the quick disassembly and installation of the coil isolator 21.

[0022] During the installation process, the spherical part of the positioning pin 28 is aligned with the sliding groove 22. The positioning plate 25 is pushed to move the positioning pin 28 to the positioning hole 23. The positioning plate 25 is rotated to insert the spherical part of the positioning pin 28 into the positioning hole 23, thereby snapping the spherical part of ...

[0023] During the process of disassembling the spool after the tape is unloaded, rotating the positioning plate 25 causes the positioning pin 28 to move to the sliding groove 22, allowing the spool separator 21 to be quickly removed. The sliding groove 22 and positioning hole 23 on the spool support rod 2, in conjunction with the spool separator 21, enable quick clamping of the winding spool and flexible adjustment of the spacing. The spherical structure of the positioning pin 28, in conjunction with the positioning spring 27, makes the locking and disassembly of the spool separator 21 convenient, adapting to the installation requirements of large-package winding spools of different specifications, while separating adjacent spools to prevent them from rubbing against each other. The end of the positioning pin 28 away from the positioning spring 27 has a spherical structure, which can effectively reduce the friction between the positioning pin 28 and the coil support rod 2 and extend the service life of the coil support rod 2. The spherical end can be inserted into the positioning hole 23 to achieve positioning, and the rotating positioning plate 25 can drive the positioning pin 28 to slide into the sliding groove 22 to achieve unlocking. The spherical structure makes the positioning and unlocking of the coil isolation piece 21 more convenient and faster.

[0024] Reference Figure 1 , Figure 5 , Figure 6 The first embodiment of the webbing cushioning assembly 5: The webbing buffer assembly 5 includes a damping assembly 51 fixed on the support frame 1. The damping assembly 51 includes a support cylinder 511 fixed on the support frame 1, a torsion spring 512 installed in the support cylinder 511, and a damping rod 52 sleeved in the torsion spring 512. One end of the torsion spring 512 is connected to the support cylinder 511, and the other end is connected to the damping rod 52.

[0025] During installation, the webbing is inserted from the lower side of the damping rod 52 between the damping rod 52 and the webbing flipping rod 54, and then to the upper side of the webbing flipping rod 54, so that the webbing is installed on the webbing buffer assembly 5 in an S-shape. When the webbing traction assembly 6 pulls the webbing, the elastic torque between the support cylinder 511 and the torsion spring 512 is used to achieve buffering, thereby effectively offsetting the buffer sway during the unwinding process, stabilizing the webbing tension, and preventing the webbing from stretching, deforming or breaking. It can be adapted to synchronous unwinding of multiple reels. Reference Figure 1 , Figure 7 , Figure 8 , Figure 9 The second implementation of the webbing cushioning component 5: The webbing buffer assembly 5 includes a support member 55 fixed on the support frame 1, damping rods 52 symmetrically fixed on both sides of the support member 55, damping cylinders 56 sleeved on the damping rods 52, a torsion spring 512 between the damping rods 52 and the damping cylinders 56, flip plates 53 fixed at both ends of the damping cylinders 56, a limiting channel formed between the flip plates 53, a webbing flipping rod 54 fixed on the flip plates 53, and a partition 57 between the damping cylinders 56. The partition 57 is fixed on the damping rods 52 and is used to prevent the damping cylinders 56 from affecting each other.

[0026] The damping cylinders 56 are separated by the partition 57 to effectively counteract the buffer sway during the webbing process, stabilize the webbing tension, and prevent the webbing from stretching, deforming or breaking. It can be adapted to synchronous webbing of multiple reels while ensuring the independence of multi-webbing anti-buffering operations.

[0027] In the second embodiment of the webbing buffer assembly 5, the support 55 can be replaced with the damping assembly 51 in the second embodiment to improve the buffering effect. Through double buffering, the tension of the webbing can be further stabilized to prevent the webbing from being stretched, deformed or broken. It can be adapted to synchronous feeding of multiple reels.

[0028] Reference Figure 1 , Figure 10The webbing traction assembly 6 includes a drive roller 61 and a limiting roller 62 mounted on a support frame 1. The drive roller 61 is driven by a drive motor. A sliding block 63 is mounted on the support frame 1, and a displacement telescopic component 64 is mounted on the support frame 1. The displacement telescopic component 64 is used to control the up and down displacement of the sliding block 63. A ratchet 65 is mounted on the sliding block 63, and the limiting roller 62 is mounted on the ratchet 65. The limiting roller 62 is made of rubber. When the limiting roller 62 is in contact with the drive roller 61, it clamps the webbing. Under the action of the ratchet 65, the webbing is prevented from moving in the opposite direction. During the installation of the webbing, the webbing is placed between the drive roller 61 and the limit roller 62 (the drive roller 61 and the limit roller 62 are rubber rollers). The sliding block 63 is lowered by the displacement telescopic component 64 (the displacement telescopic component 64 can be a cylinder or an electric screw), so that the drive roller 61 and the limit roller 62 are in contact. The drive motor drives the drive roller 61 to rotate, and under the action of clamping force and friction, the ribbon is pulled to move and the ribbon is conveyed. A ratchet 65 is installed on the sliding block 63, and a limiting roller 62 is installed on the ratchet 65, so that the limiting roller 62 can only rotate in one direction. The webbing traction assembly 6 adopts the clamping and traction structure of the driving roller 61 and the limiting roller 62. With the help of the displacement telescopic component 64, the clamping tightness can be easily adjusted to adapt to different webbing types. The one-way limiting function of the ratchet 65 solves the problem of reverse displacement of the webbing.

[0029] Reference Figure 1 , Figure 10 A control center 66 is installed on the support frame 1, and a control switch 67 is installed on the support frame 1. The control center 66, the control switch 67, the displacement telescopic component 64 and the drive motor are electrically connected. The control switch 67 controls the extension and retraction of the displacement telescopic component 64. The electrical connection design between the control center 66 and the control switch 67 improves the automation and ease of operation of the traction operation.

[0030] Reference Figure 1 , Figure 10 , Figure 11 The webbing limiting assembly 7 includes a support plate 71 fixed on the support frame 1. A pair of parallel feeding rods 72 are fixed on the support plate 71. Multiple dividing plates 73 are installed on the feeding rods 72. The ribbon, after being pulled by the webbing traction assembly 6, is limited by the webbing limiting assembly 7. The dividing plates 73 divide the feeding rods 72 into multiple feeding channels. The feeding channels correspond to the limiting channels, thereby ensuring that each ribbon moves on the same straight line, thereby further improving the stability of the ribbon conveying and preventing the ribbons from tangling.

[0031] Reference Figure 1 , Figure 10 , Figure 11An upper eccentric wheel 74 and a lower eccentric wheel 75 are installed on the feed rod 72. A flip spring 76 is installed between the lower eccentric wheel 75 and the feed rod 72. The flip spring 76 is used to control the lower eccentric wheel 75 to be in contact with the upper eccentric wheel 74. The lower eccentric wheel 75 and the upper eccentric wheel 74 are used to control the unidirectional displacement of the webbing. During the forward conveying of the ribbon, the upper eccentric wheel 74 and the lower eccentric wheel 75 will not generate squeezing force under the action of friction, so the ribbon can be conveyed stably. When the ribbon is subjected to a reaction force, it moves in the opposite direction. The upper eccentric wheel 74 flips downward under the action of gravity, and the lower eccentric wheel 75 deflects upward under the action of the flip spring 76. The upper eccentric wheel 74 and the lower eccentric wheel 75 come together to generate squeezing force, which clamps the ribbon. So that after the webbing traction component 6 is released, the ribbon is subjected to clamping force, so that the ribbon will not be misaligned. During the ribbon installation process, the ribbon can be clamped by the upper eccentric wheel 74 and the lower eccentric wheel 75, so that the ribbon can be installed in place more quickly without the need for auxiliary tools.
