[0040] At present, conventional cigarette boxes include small cigarette boxes and strip boxes. Small cigarette boxes are used to hold cigarettes, and strip boxes are used to hold small cigarette boxes. Strip boxes generally include a leather shell and a surrounding frame, and the surrounding frame generally adopts a bottomless surrounding frame with a hollow bottom. Before the bottomless surrounding frame is bonded to the leather shell, a lining paper needs to be bonded to the bottom surface of the bottomless surrounding frame to cover the bottom of the leather shell, so that the strip box is neater and more beautiful. Some strip boxes also have ribbons. The ribbons are pasted on the surrounding frame to make the strip box more beautiful, but adding the ribbons will interfere with the fitting of the lining paper, thereby greatly increasing the difficulty of pasting the lining paper on the surrounding frame, which makes the existing lining device difficult to implement.

[0041] In view of this, the present invention provides a lining device. Figures 1 to 5 The present invention provides an embodiment of a lining device.

[0042] See also Figure 1 to Figure 2 A pasting device 100 is used to adhere a backing paper 300 to the bottom of a surrounding frame 200 with a ribbon 400. The pasting device 100 includes: a base 10, a limiting mechanism, a negative pressure mechanism and a transport mechanism. A bonding station 12 is provided on the base 10; the limiting mechanism is used to limit the surrounding frame 200 at the bonding station 12; the negative pressure mechanism is used to move the free end of the ribbon 400 out of the surrounding frame 200 after the limiting mechanism limits the surrounding frame 200; the transport mechanism includes a transport member 40 movably arranged on the base 10, the transport member 40 has a movement stroke approaching and moving away from the bonding station 12, and the transport member 40 is used to transport the backing paper 300 to the bonding station 12 when the ribbon 400 is sucked out, so as to add the backing paper 300 to the bottom of the surrounding frame 200.

[0043] In the technical solution of the present invention, the frame 200 is fixed on the bonding station 12 by arranging the limiting mechanism on the base 10, and then the free end of the ribbon 400 is moved out of the frame 200 by the negative pressure mechanism, and the transport mechanism can then transport the backing paper 300 to the bottom of the frame 200 through the transport member 40 for lining, and because one end of the ribbon 400 is moved out of the frame 200, the backing paper 300 is no longer disturbed by the ribbon 400, so that lining can be completed. The lining device 100 proposed by the present invention can move the ribbon 400 out of the frame 200, thereby eliminating the influence of the ribbon 400 on lining, and realizes the automatic lining of the frame 200 with the ribbon 400.

[0044] For further information, see Figure 1 , Figure 2 and Figure 4 The pasting device 100 also includes a shaping mechanism, which includes a reference block 31 movably arranged at the bonding station 12 and a driver 23 for driving the reference block 31. The reference block 31 is used to abut against the side wall of the frame 200 so as to push the side wall of the frame 200 to a standard shape when the side wall of the frame 200 is deformed outward.

[0045] In this embodiment, Figure 4The direction indicated by the middle arrow is the material feeding direction of the enclosure 200. During the actual processing of the enclosure 200, the two side walls may expand outwardly toward the outside of the enclosure 200. At this time, the shape of the enclosure 200 changes, which may interfere with the subsequent processing. Therefore, in this embodiment, the shaping mechanism is provided, and the shaping mechanism includes a reference block 31 movably arranged at the bonding station 12 and a driver 23 corresponding to the reference block 31. The reference block 31 has a movement stroke approaching and moving away from the enclosure 200 under the drive of the driver 23, and when the reference block 31 approaches the enclosure 200, the reference block 31 pushes against the longer side wall of the enclosure 200 that has expanded outwardly, thereby pushing and shaping the enclosure 200 to a standard shape.

[0046] Furthermore, a suction cup 30 is provided on the reference block 31 , and the suction side of the suction cup 30 is arranged toward the surrounding frame 200 , so as to suck the side wall of the surrounding frame 200 to a standard shape when the surrounding frame 200 is deformed concavely.

[0047] In this embodiment, the side walls of the enclosure 200 may also deform inwardly toward the inside of the enclosure 200 during actual processing. At this time, the shape of the enclosure 200 changes, which may interfere with subsequent processing. Therefore, the shaping mechanism also includes the suction cup 30 installed on the reference block 31, so that when the reference block 31 moves toward the enclosure 200, the suction cup 30 will suck the side walls of the enclosure 200 back to the standard shape. The reference block 31 and the suction cup 30 are used in conjunction, so that when the enclosure 200 deforms outward or inward, the shaping mechanism can adjust the enclosure 200 to the standard shape, thereby ensuring the normal operation of the lining device 100 and improving the lining efficiency.

[0048] It should be noted that the driver 23 can be a driving device such as a cylinder, a motor, etc., as long as it can drive the reference block 31, and the specific structure is not limited here.

[0049] For further information, see Figure 1 and Figure 4 The negative pressure mechanism includes: a removal member 50 and a negative pressure device. The removal member 50 is arranged above the bonding station 12, and the removal member 50 is provided with a removal hole 52 for being arranged toward the ribbon 400; the negative pressure device is used to connect with the removal hole 52 to form a negative pressure in the removal hole 52, so as to attract the free end of the ribbon 400 to enter the removal hole 52.

[0050] In this embodiment, Figure 4The direction indicated by the arrow is the material feeding direction of the enclosure 200. When the lining paper 300 is pasted on the enclosure 200, the free end of the ribbon 400 may be located at the bonding point between the lining paper 300 and the enclosure 200, thereby interfering with the bonding between the enclosure 200 and the lining paper 300. Therefore, the negative pressure mechanism is provided with the removal member 50. The removal member 50 sucks the free end of the ribbon 400 into the removal hole 52 through negative pressure, so that the ribbon 400 will not be located directly above the opening of the enclosure 200, avoiding the descending stroke of the lining paper 300, thereby ensuring that the ribbon 400 will not interfere with the bonding between the lining paper 300 and the enclosure 200.

[0051] For further information, see Figure 3 A pressing block 51 is provided in the removal member 50 , and the pressing block 51 has a radial movable stroke toward the removal hole 52 , and the pressing block 51 is used to press the ribbon 400 when the ribbon 400 extends along the removal hole 52 .

[0052] There is a certain allowable error in the tightness between the lining paper 300 and the inner circumference of the frame 200, and all the frame products within this error range are qualified. When the area of ​​the lining paper 300 is less than or equal to the area of ​​the bottom surface of the frame 200, the negative pressure mechanism can directly hold the ribbon 400 through the negative pressure adsorption capacity to prevent it from slipping; however, within the allowable error range, there are also some areas of the lining paper 300 that are slightly larger than the bottom area of ​​the frame 200. Such lining paper 300 will inevitably scratch the ribbon 400 when it moves downward on the inner wall of the frame 200, and there is a risk of dragging the ribbon 400 downward. Based on this problem, in the present embodiment, the pressing block 51 is further provided in the removal member 50, so that when the pressing block 51 moves radially along the removal hole 52, the pressing block 51 will press the ribbon 400 from the vertical direction of the ribbon 400, thereby further ensuring that the ribbon 400 will not be scratched and fall off by the downward lining paper 300 or even return to the bonding area between the surrounding frame 200 and the lining paper 300, thereby reducing the risk and improving the qualified rate of the surrounding frame 200 in the lining device 100.

[0053] For further information, see Figure 2The limiting mechanism includes a first limiting component, which includes a rotating arm 20 and a driving cylinder 22. The plurality of rotating arms 20 are arranged at opposite sides of the bonding station 12, each of the rotating arms 20 has a clamping end close to the bonding station 12 and a rotating end arranged opposite to the clamping end, and the rotating end is rotatably mounted on the base 10 to drive the clamping end to rotate toward or away from the bonding station 12; the plurality of driving cylinders 22 are arranged in a one-to-one correspondence with the plurality of rotating arms 20, and each of the driving cylinders 22 is drivingly connected to the corresponding clamping end to drive the clamping end to rotate toward the bonding station 12, so that the plurality of rotating arms 20 clamp and limit the long side of the surrounding frame 200 together.

[0054] In this embodiment, the first limiting component limits the frame 200 by setting a plurality of the rotating arms 20, and the driving cylinders 22 are set one by one corresponding to the rotating arms 20, so that when the rotating arms 20 are driven by the corresponding driving cylinders 22, the clamping ends will rotate toward the bonding station 12, so that the plurality of rotating arms 20 will clamp the frame 200 of the bonding station 12 in the middle, thereby fixing the frame 200 in the width direction of the frame 200.

[0055] Furthermore, the limiting mechanism further includes a second limiting component, which includes: a clamping arm 21 and a driver 23. The plurality of clamping arms 21 are movably arranged on the peripheral side of the bonding station 12, and the clamping arm 21 has an angle block 24 arranged close to the bonding station 12, and a driving end arranged relative to the angle block 24; the plurality of drivers 23 are arranged in a one-to-one correspondence with the plurality of clamping arms 21, and the driver 23 is drivingly connected to the corresponding driving end, so that when the plurality of clamping arms 21 are close to the bonding station 12, the plurality of angle blocks 24 jointly clamp and limit the top angle of the surrounding frame 200.

[0056] In this embodiment, the clamping arms 21 and the drivers 23 are arranged in a one-to-one correspondence, and each of the clamping arms 21 has a movement stroke approaching and moving away from the bonding station 12 under the drive of the corresponding driver 23. The angle block 24 is arranged at one end of the clamping arm 21 close to the bonding station 12, so that when the driver 23 drives the clamping arm 21 to approach the bonding station 12, the angle blocks 24 on the plurality of clamping arms 21 arranged opposite to each other will clamp and limit the surrounding frame 200 together, thereby fixing the surrounding frame 200 in the length direction of the surrounding frame 200.

[0057] It should be noted that the driver 23 can be a driving device such as a cylinder, a motor, etc., as long as it can drive the clamping arm 21, and the specific structure is not limited here.

[0058] For further information, see Figure 1 The transport mechanism also includes a first driving member 41, which is drivingly connected to the transport member 40, and is used to drive the transport member 40 to approach and move away from the bonding station 12; the transport member 40 is provided with a plurality of suction holes toward the bonding station 12, and the plurality of suction holes are used to absorb the backing paper 300, so that when the transport member 40 approaches the bonding station 12, the backing paper 300 is placed at the bottom of the frame 200.

[0059] In this embodiment, the transport mechanism further includes the first driving member 41 for driving the transport member 40. When the transport member 40 needs to absorb the backing paper 300 through the suction hole, the first driving member 41 drives the transport member 40 to move away from the bonding station 12 to the storage area of ​​the backing paper 300. After the transport member 40 absorbs the backing paper 300, the first driving member 41 drives the transport member 40 to move toward the bonding station 12. When the transport member 40 approaches the bonding station 12, the transport member 40 puts the backing paper 300 into the bottom of the enclosure 200. In this way, the transport mechanism completes the lining of the enclosure 200.

[0060] For further information, see Figure 1 to Figure 2 The base 10 includes a first base 10 and a second base 10 which are relatively spaced apart, and the second base 10 is movably arranged in a direction approaching and moving away from the first base 10; the lining device 100 also includes an adjusting screw 11, and the adjusting screw 11 is arranged on the first base 10. The second base 10 is provided with a screw nut corresponding to the adjusting screw 11, so as to drive the second base 10 to approach or move away from the first base 10 when the adjusting screw 11 is rotated by an external force.

[0061] In this embodiment, the base 10 includes the first base 10 and the second base 10, and the partial areas on the first base 10 and the second base 10 together constitute the bonding area. The first base 10 and the second base 10 are adjustably connected through the adjusting screw 11 and the screw nut. When the adjusting screw 11 is adjusted, the screw nut drives the second base 10 to move together, thereby adjusting the size of the bonding area, so that the lining device 100 in this embodiment can meet the needs of lining different frames 200.

[0062] For further information, see Figure 1 and Figure 4In this embodiment, the negative pressure mechanism can be disposed obliquely above or below the bonding station in actual application, without any specific limitation, as long as the negative pressure mechanism can suck the free end of the ribbon 400 out of the surrounding frame 200.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
