Detailed implementation mode

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. Obviously, the described embodiments of the present application are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0023] See Figures 1 to 3 A feeding device as shown, including a fixed frame 100 and a transmission mechanism arranged on the fixed frame 100. The strip 10 is arranged on the transmission mechanism so as to be able to move along its own length direction. The material is attached to the surface of the strip 10, and the transmission of the material is realized by transmitting the strip 10. The transmission mechanism includes a swing seat 11, and a peeling member 12 and an attaching member 13 are arranged on the swing seat 11. The peeling member 12 has a feeding surface 121 and a discharging surface 122 arranged opposite to each other. See Figure 8 As shown, the feeding surface 121 and the discharging surface 122 are connected and form a stripping end 123 that can strip the material from the strip 10. The strip 10 sequentially passes around the feeding surface 121, the stripping end 123 and the discharging surface 122 along the length direction. The attaching member 13 is arranged at a gap with the feeding surface 121 and forms a channel for the strip 10 with the material to pass through. At least part of the attaching member 13 extends on one side of the stripping end 123.

[0024] In this embodiment, after the strip 10 passes around the stripping end 123, the material is peeled off from the strip 10. At this time, the feeding device can be driven to approach the product relatively to attach the material to the product, and then by driving the feeding device and the product to move relatively, the attaching member 13 can press and adhere the material tightly to the surface of the product. In this way, the feeding device can not only realize the function of material transmission, but also perform the operation of attaching the material. In this embodiment, the attaching member 13 is suspended and arranged at the stripping end 123, which can prevent the stripping end 123 from interfering with the pressing operation of the attaching member 13.

[0025] In this embodiment, the swing seat 11 has a connecting end 111 and a swing end 112 arranged at intervals. The connecting end 111 is rotatably arranged on the fixed frame 100 around the first rotation center line X1, and the first rotation center line X1 is parallel to the width extension direction of the strip 10. The stripping member 12 and the attaching member 13 are both arranged on the swing end 112. In this embodiment, the feeding device further includes an adjusting mechanism 14 for adjusting the position of the swing seat 11 on the fixed frame 100. The adjusting mechanism 14 is connected between the swing seat 11 and the fixed frame 100. By driving the swing seat 11 to rotate through the adjusting mechanism 14, on the one hand, it can drive the stripping end 123 and the attaching member 13 to rotate, so as to adjust the angles of the two, so as to realize the material attaching operation at different angles. On the other hand, the distance between the attaching member 13 and the product can be adjusted to adjust the magnitude of the pressing force applied by the attaching member 13 on the material and the product. At the same time, the strip 10 can be maintained in a tensioned state by rotating the swing seat 11 to ensure the normal execution of the material stripping and attaching operations.

[0026] In this embodiment, the strip 10 on one side of the feeding surface 121 is transmitted in the first direction, and the strip 10 on one side of the discharging surface 122 is transmitted in the second direction. The first direction intersects with the second direction, and the stripping end 123 abuts against the strip 10. In this way, the strip 10 forms a corner at the stripping end 123. Due to the different stiffness of the material and the strip 10, when the strip 10 passes through the stripping end 123, the material can be peeled off from the strip 10. Specifically, the strip 10 has a first side surface and a second side surface respectively arranged on different sides in the thickness direction. The material is located on the first side surface, and the stripping end 123 abuts against the second side surface. In this embodiment, the feeding surface 121 and the discharging surface 122 form an acute angle, which is more conducive to peeling the material from the strip 10.

[0027] See Figure 8 As shown, in this embodiment, the stripping member 12 is wedge-shaped, and the tip of the wedge forms the stripping end 123. The second side surface of the strip 10 abuts against the tip. The two side surfaces in the thickness direction of the stripping member 12 respectively form the feeding surface 121 and the discharging surface 122, and the feeding surface 121 and the discharging surface 122 are arranged adjacent to the tip. See Figures 6 to 8 As shown, in the figure, the feeding surface 121 faces upward and the discharging surface 122 faces downward.

[0028] In some embodiments, the strip 10 does not contact or is not fully in close contact with the feeding surface 121 and the discharging surface 122 when winding around the feeding surface 121 and the discharging surface 122. Preferably, the first direction is parallel to the extending direction of the feeding surface 121, and the second direction is parallel to the extending direction of the discharging surface 122. More preferably, the strip 10 is in close contact with the feeding surface 121 during transmission, and the strip 10 is in close contact with the discharging surface 122 during transmission to ensure the success rate of material peeling.

[0029] In this embodiment, the peeling member 12 further has a plate-like structure extending away from the stripping end 123, which is used to improve the connection stability between the peeling member 12 and the swing seat 11, and can form an extended surface that is connected to the feeding surface 121 and extends away from the stripping end 123, providing better guidance for the transmission of the strip 10 along the first direction towards the stripping end 123, ensuring that the strip 10 can be stably transmitted, and ensuring the peeling rate of the material.

[0030] See Figure 8 As shown, in this embodiment, a limiting block 16 is provided on the peeling member 12. The limiting block 16 is arranged on one side of the feeding surface 121, and the limiting block 16 can adjust its position along the direction parallel to the width of the strip 10. The limiting block 16 is used to limit the displacement of the strip 10 in the width direction, prevent the strip 10 from moving in the width direction, and thus improve the attachment accuracy of the material. By adjusting the position of the limiting block 16, the width of the channel between the stripping end 123 and the attaching member 13 can be changed to adapt to strips 10 of different widths.

[0031] In this embodiment, the feeding device includes a pressing roller shaft rotatably arranged on the swing seat 11. The pressing roller shaft constitutes the attaching member 13, and the axis of the pressing roller shaft is parallel to the first rotation center line X1. By driving the pressing roller shaft to press the material against the product and roll relative to the product, the rolling pressure of the material is realized, thereby completing the attachment of the material.

[0032] In this embodiment, the adjusting mechanism 14 has a driving member 141 that is movably arranged. The driving member 141 is rotatably connected to the swing seat 11 around the second rotation center line X2, and the swing seat 11 can be driven to rotate by driving the driving member 141 to move. In some embodiments, the driving member 141 is movably arranged on the fixed frame 100. Specifically, the adjusting mechanism 14 includes a cylinder 142, and the driving member 141 is driven to move by the cylinder 142. In this embodiment, the cylinder 142 is connected to the fixed frame 100 through a cross bar 143. The axis line of the cross bar 143 is parallel to the first rotation center line X1. The angle of the cylinder 142 can be adjusted by driving the cylinder 142 to rotate around the axis line of the cross bar 143 to adapt to different working scenarios. In some embodiments, the driving member 141 is arranged to be able to extend and contract in length, and the position of the swing seat 11 is adjusted by extending and contracting in length. Specifically, the driving member 141 is the telescopic shaft of the cylinder 142.

[0033] In this embodiment, the feeding device includes a guide roller 15 rotatably arranged on the swing seat 11. The strip 10 sequentially winds around the guide roller 15, the feeding surface 121 and the stripping end 123 along the length direction. The strip 10 is tensioned between the guide roller 15 and the stripping end 123. The axis line of the guide roller 15 is parallel to the first rotation center line X1. The guide roller 15 is used to guide the transmission of the strip 10, so that the strip 10 between the guide roller 15 and the stripping end 123 is transmitted in the first direction. Preferably, under the guiding action of the guide roller 15, the strip 10 closely adheres to the feeding surface 121.

[0034] In this embodiment, the peeling member 12 and the attaching member 13 are arranged such that their positions are adjustable in the first direction, so that the relative positional relationship between the peeling member 12 and the attaching member 13 can be adjusted according to requirements to adapt to different usage scenarios. Specifically, the swinging seat 11 has two mounting plates 113 arranged at intervals along the width extension direction of the strip 10. The guiding roller 15 is rotatably arranged between the two mounting plates 113. The peeling member 12 is mounted between the two mounting plates 113. The two ends of the attaching member 13 are respectively connected to the two mounting plates 113 through connecting members 17, and the attaching member 13 is rotatably arranged between the two connecting members 17. The two sides of the peeling member 12 are connected to the two mounting plates 113 through a chute structure. The two connecting members 17 are respectively connected to the two mounting plates 113 through a chute structure. Locking components are respectively provided between the side portion of the peeling member 12 and the mounting plate 113, and between the connecting member 17 and the mounting plate 113, and are respectively used to lock the peeling member 12 relative to the mounting plate 113 and lock the connecting member 17 relative to the mounting plate 113. When the locking between the peeling member 12 and the mounting plate 113 is released, the two can be driven to slide relative to each other to adjust the position of the peeling member 12. When the locking between the connecting member 17 and the mounting plate 113 is released, the two can be driven to slide to adjust the position of the attaching member 13. In this embodiment, the locking component includes a lock hole and a lock pin that can be inserted into the lock hole.

[0035] In this embodiment, the swinging seat 11 includes a connecting plate 114 connected between the two mounting plates 113. The driving member 141 is rotatably connected to the connecting plate 114 around the second rotation center line.

[0036] In this embodiment, the transmission mechanism includes a floating roller shaft 51. The floating roller shaft 51 is rotatable and can slide up and down on the fixed frame 100. The strip 10 passes around the lower side of the floating roller shaft 51, and the floating roller shaft 51 is supported on the strip 10. When the tension of the strip 10 changes, the floating roller shaft 51 will move in the up and down direction. For example, when the strip 10 is slack, the supporting force of the strip 10 on the floating roller shaft 51 decreases, and the floating roller shaft 51 will move downward under the action of gravity. By detecting the position of the floating roller shaft 51, the tension of the strip 10 can be judged. At the same time, when the floating roller shaft 51 moves downward, it can drive the strip 10 to move downward together, thereby alleviating the slack state of the strip 10 and making it taut.

[0037] In this embodiment, the transmission mechanism includes a driving roller shaft 41 and a driven roller shaft 42. The driving roller shaft 41 is rotatably arranged on the fixed frame 100, and the driven roller shaft 42 is rotatably arranged on the fixed frame 100. The strip 10 passes between the driving roller shaft 41 and the driven roller shaft 42. The transmission mechanism further includes a driving assembly 43 for driving the driving roller shaft 41 to rotate. The driving roller shaft 41 can provide the torque for the forward transmission of the strip 10. By clamping the strip 10 between the driving roller shaft 41 and the driven roller shaft 42, the strip 10 can be transmitted forward under the drive of the driving roller shaft 41.

[0038] In this embodiment, the feeding device includes a loading mechanism 2 and a collecting mechanism 3. The loading mechanism 2 is used to provide the strip 10 with attached materials, and the collecting mechanism 3 is used to recover the strip 10. The strip 10 is transmitted from the loading mechanism 2 to the collecting mechanism 3. Specifically, the collecting mechanism 3 includes a collecting shaft 31, and the collecting shaft 31 is rotatably arranged on the fixed frame 100. The transmission mechanism is provided with a driving mechanism 32 for driving the collecting shaft 31 to rotate. The strip 10 is connected to the collecting shaft 31 and can be wound around the collecting shaft 31. By driving the collecting shaft 31 to rotate to drive the strip 10 to be transmitted forward, the collecting mechanism 3 can also provide the torque required for the transmission of the strip 10.

[0039] In this embodiment, the torque of the transmitted strip 10 is adjusted through the cooperation of the transmission mechanism and the collecting mechanism 3, so that the strip 10 is in a taut state. Specifically, in this embodiment, the driven roller shaft 42 is arranged on the fixed frame 100 so as to be able to move relatively far away from or close to the driving roller shaft 41. The driven roller shaft 42 has a first position and a second position. When in the first position, the driven roller shaft 42 is close to the driving roller shaft 41, and the strip 10 is clamped between the driving roller shaft 41 and the driven roller shaft 42. The driving roller shaft 41 participates in and provides the torque for the transmission of the strip 10. When the driven roller shaft 42 is in the second position, the driven roller shaft 42 is far away from the driving roller shaft 41, and the distance between the driven roller shaft 42 and the driving roller shaft 41 is greater than the thickness of the strip 10, so that the strip 10 is separated from the driving roller shaft 41, and the driving roller shaft 41 does not participate in providing the torque for the transmission of the strip 10.

[0040] In this embodiment, the feeding device is provided with a detection mechanism 52, which is used to detect whether the position of the floating roller shaft 51 has changed. The feeding device is provided with a conversion mechanism 44 for driving the driven roller shaft 42 to move between a first position and a second position, and the detection mechanism 52 is in signal connection with the conversion mechanism 44. When the detection mechanism 52 detects that the floating roller shaft 51 moves, the detection mechanism 52 can send a signal to the conversion mechanism 44, and the conversion mechanism 44 can drive the driven roller shaft 42 to adjust between the first position and the second position based on the received signal. Specifically, the floating roller shaft 51 has a warning height relative to the fixed frame 100. When the detection mechanism 52 detects that the height of the floating roller shaft 51 is lower than the warning height, that is, the material tape 10 is slack, the detection mechanism 52 sends a signal to the conversion mechanism 44, and the conversion mechanism 44 drives the driven roller shaft 42 to move from the second position to the first position, so that the driving roller shaft 41 participates in providing torque to jointly solve the problem of the slack of the material tape 10.

[0041] In this embodiment, the material tape 10 sequentially passes through the swing seat 11, between the driving roller shaft 41 and the driven roller shaft 42, the floating roller shaft 51 along the length direction, and finally reaches the material receiving mechanism 3. The floating roller shaft 51 can timely detect the problem of the slack of the material tape 10 caused by insufficient torque, and can also timely detect the adjustment situation of the material tape 10 after the driving roller shaft 41 participates in providing torque. In this embodiment, the swing seat 11, the driving roller shaft 41 and the floating roller shaft 51 can form a synergistic effect. When the swing seat 11 is driven to adjust the fitting angle or the pressing force, if the tension or slack of the material tape 10 changes, the material tape 10 can be adjusted in time through the floating roller shaft 51 or the driving roller shaft 41.

[0042] In this embodiment, the driving roller shaft 41 is located below the driven roller shaft 42, the driven roller shaft 42 is arranged on the fixed frame 100 so as to be able to move up and down, and the conversion mechanism 44 is used to drive the driven roller shaft 42 to move up and down. In this embodiment, the conversion mechanism 44 includes an electric cylinder, and the driven roller shaft 42 is driven to move up and down by the electric cylinder.

[0043] In this embodiment, the fixed frame 100 is provided with a guide rail 110 extending in the up and down direction, the feeding device is provided with a sliding member 120, the sliding member 120 is slidably arranged on the guide rail 110, and the floating roller shaft 51 is rotatably connected to the sliding member 120. In this embodiment, two floating roller shafts 51 are provided, and the material tape 10 sequentially passes around the lower sides of the two floating roller shafts 51 along the length direction, and the two floating roller shafts 51 are arranged to move synchronously in the up and down direction. Refer to Figure 2 、 Figure 3 As shown in, in this embodiment, the two floating roller shafts 51 are rotatably connected to the sliding member 120. Arranging two floating roller shafts 51 can provide more sufficient tension and can also respond more quickly to the slack of the material tape 10.

[0044] In this embodiment, the feeding device is provided with a clamping mechanism 6. The clamping mechanism 6 is located upstream of the swing seat 11 along the length direction of the strip. Specifically, the clamping mechanism 6 is located between the feeding mechanism 2 and the swing seat 11. The clamping mechanism 6 includes a first roller 61 and a second roller 62. The first roller 61 and the second roller 62 are rotatably arranged on the fixed frame 100, and the strip 10 passes between the first roller 61 and the second roller 62. The clamping mechanism has a clamping state. In the clamping state, the strip 10 is clamped between the first roller 61 and the second roller 62. On the one hand, it can straighten the strip 10 for subsequent operations of stripping the material and attaching the material. On the other hand, it can apply resistance to the movement of the strip 10 to maintain the tension state of the strip 10.

[0045] In this embodiment, the first roller 61 is eccentrically rotatably arranged on the fixed frame 100 around a first rotation axis, and the second roller 62 is rotatably arranged on the fixed frame 100 around a second rotation axis. As the first roller 61 eccentrically rotates, the clamping mechanism 6 periodically switches to the clamping state. Specifically, the feeding device includes an eccentric shaft 63 arranged on the fixed frame 100. The first roller 61 is movably sleeved on the eccentric shaft 63 and can eccentrically rotate around the eccentric shaft 63. In this embodiment, the axis line of the second roller 62 extends collinearly with the second rotation axis. In some embodiments, the second roller 62 can also be eccentrically rotatably arranged. Specifically, referring to Figure 4 As shown, the fixed frame 100 has a frame body and a fixing plate 130. The fixing plate 130 is spaced from the frame body of the fixed frame 100. The first roller 61 and the second roller 62 are rotatably arranged between the frame body of the fixed frame 100 and the fixing plate 130.

[0046] In this embodiment, the eccentric shaft 63 is rotatably arranged on the fixed frame 100 around the first rotation axis. By driving the eccentric shaft 63 to rotate, the eccentric angle of the first roller 61 can be adjusted, and then the distance between the first roller 61 and the second roller 62 in the clamping state can be adjusted to adapt to strips 10 of different thicknesses or strips 10 carrying materials of different thicknesses. In this embodiment, a locking mechanism is provided between the eccentric shaft 63 and the fixed frame 100. The locking mechanism includes a locking member 641 fixedly arranged on the eccentric shaft 63. When the locking mechanism is in the locked state, the locking member 641 cooperates with the fixed frame 100 to lock the eccentric shaft 63 relative to the fixed frame 100. When the locking mechanism is in the unlocked state, the locking member 641 is disengaged from the fixed frame 100, so that the eccentric shaft 63 can rotate relative to the fixed frame 100.

[0047] In this embodiment, the feeding device includes a rotary handle 64 for driving the eccentric shaft 63 to rotate. The rotary handle 64 is fixedly connected to the eccentric shaft 63. The operator can rotate the rotary handle 64 to drive the eccentric shaft 63 to rotate, thereby adjusting the eccentricity of the first roller 61. Referring to Figure 4 、Figure 5 As shown, the locking member 641 is fixedly arranged on the rotary handle 64, and the locking member 641 extends from the rotary handle 64 towards the fixing frame 100. In this embodiment, the locking mechanism includes a locking groove 140 arranged on the fixing frame 100. When the locking mechanism is in the locked state, the locking member 641 is inserted into the locking groove 140. When in the unlocked state, the locking member 641 disengages from the locking groove 140.

[0048] Specifically, a plurality of locking grooves 140 are arranged on the fixing plate 130. The eccentric shaft 63 is also slidably arranged on the fixing frame 100 along the axial direction, and the eccentric shaft 63 can be driven to slide by the rotary handle 64. During the process of the rotary handle 64 sliding along the axial direction of the eccentric shaft 63, the locking member 641 fixed to the rotary handle 64 can move relatively away from or relatively close to the fixing plate 130, so as to be inserted into the locking groove 140 or disengage from the locking groove 140. In this embodiment, when adjusting the distance between the first roller 61 and the second roller 62, the rotary handle 64 is pulled in the direction away from the fixing frame 100, so that the locking member 641 disengages from the locking groove 140, and the locking between the eccentric shaft 63 and the fixing frame 100 is released. Then, the rotary handle 64 is used to drive the eccentric shaft 63 to rotate. After rotating to the expected position and when the locking member 641 corresponds to the position of another locking groove 140, the rotary handle 64 is pushed in the direction close to the fixing frame 100, so that the locking member 641 is inserted into the locking groove 140, and the eccentric shaft 63 and the fixing frame 100 are locked to each other.

The tension rollers 7 are arranged in the transmission path of the material tape 10, and the material tape 10 abuts against the tension rollers 7. On the one hand, it provides guidance for the transmission of the material tape 10, and on the other hand, it makes the material tape 10 in a tensioned state. Specifically, as shown in Figures 1 to 3 As shown, the tension rollers 7 are arranged between the feeding mechanism 2 and the swing seat 11, between the swing seat 11 and the driving roller shaft 41, and between the driving roller shaft 41 and the floating roller shaft 51. In this embodiment, the axis lines of the tension rollers 7, the axis line of the expansion shaft 21, the axis line of the driving roller shaft 41, the axis line of the driven roller shaft 42, the axis line of the floating roller shaft 51, and the axis line of the winding shaft 31 are parallel to each other and parallel to the width extension direction of the material tape 10.

[0051] In this embodiment, the material is a label or film body that can adhere to the surface of the material tape 10.

[0052] In the feeding device of this embodiment, the strip 10 moves sequentially along the length direction from the feeding mechanism 2 through the clamping mechanism 6, the guiding roller 15, the channel between the self-adhesive accessory 13 and the feeding surface 121, passes around the stripping end 123, the discharging surface 122, between the driving roller shaft 41 and the driven roller shaft 42, and under the floating roller shaft 51, and is finally transmitted to the collecting mechanism 3. The feeding device integrates two functions of conveying materials and attaching materials. The material can be closely attached to the product through the attaching accessory 13. The rotatable swing seat 11 can adjust the attaching angle and the attaching force, so that the feeding device can adapt to different scenarios. The feeding device is provided with two mechanisms, namely the driving roller shaft 41 and the collecting mechanism 3, which can provide the transmission torque of the strip 10, and is provided with a floating roller shaft 51 to detect the slack or tension degree of the strip 10. According to the position change of the floating roller shaft 51, the driven roller shaft 42 is driven to switch between the first position and the second position, so as to regulate the transmission torque of the strip 10 through the driving roller shaft 41, so that the strip 10 is in a tensioned state, ensuring the stability of the feeding device.
