A device for wrapping the edge of a disk-like material using a flexible material

Abstract

The present invention discloses a device for wrapping the edge of a disk-like material with a flexible material. The flexible packaging material is conveyed to a traction mechanism via a material feeding and withdrawing mechanism. When the head of the flexible packaging material reaches a preset position, the traction mechanism clamps the head of the flexible packaging material and pulls the head of the flexible packaging material to rotate along the circumference of the disk-like material, so that the flexible packaging material is wrapped around the disk-like material. The material withdrawal mechanism of the material feeding and withdrawing mechanism cooperates with a first pressing mechanism to make the flexible packaging material tightly adhere to the disk-like material, thereby achieving the edging of the disk-like material with the flexible packaging material. Under the rotation of the disk seat, the disk-like material is wound multiple times. Compared with the existing manual winding method, this application can not only save a lot of manpower, but also avoid the problems of uneven and loose winding.

DETAILED DESCRIPTION

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0074] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0075] The embodiment of the present invention provides a device for wrapping the edge of a disk 10-1 with a flexible material, see Figures 1 to 11 , Figure 1 Schematic diagram of the structure of a device for wrapping the edge of a disk-like disk 10-1 with a flexible material, wherein the device for wrapping the edge of a disk-like disk 10-1 with a flexible material comprises:

[0076] The disc seat 1 is used to fix the disc 10-1 and drive the disc 10-1 to rotate;

[0077] The feeding and withdrawing mechanism 2 is arranged on one side of the disc seat 1, and the withdrawing mechanism is used for feeding or withdrawing the flexible packaging material 10-2;

[0078] The traction mechanism 3 is used to clamp the head of the flexible packaging material 10-2 and pull it to rotate circumferentially around the disk 10-1;

[0079] The first pressing mechanism 4, the feeding and withdrawing mechanism 2 and the first pressing mechanism 4 are arranged along the circumference of the disc seat 1, and the first pressing mechanism 4 is used to make the flexible packaging material 10-2 close to the disc-like 10-1.

[0080] It should be noted that, by setting the disc seat 1, the disc-like 10-1 can be fixed and driven to rotate, and by setting the feeding and retracting mechanism 2, the flexible packaging material 10-2 can be conveyed to the disc-like 10-1 disc seat 1. When the head of the flexible packaging material 10-2 is conveyed to the preset position, the traction mechanism 3 can clamp the head of the flexible packaging material 10-2 and drive the head of the flexible packaging material 10-2 to rotate around the disc-like 10-1. When the traction mechanism 3 drives the head of the flexible packaging material 10-2 When the disc 10-1 is partially wound and rotates to the target position, the flexible packaging material 10-2 will cover the disc 10-1, and then the flexible packaging material 10-2 will be partially pressed against the disc 10-1 by the pressing mechanism. The feeding and withdrawing mechanism 2 withdraws the material so that the flexible packaging material 10-2 is tightly wrapped around the disc 10-1. Finally, the disc seat 1 rotates itself to drive the disc 10-1 to rotate, so that the flexible packaging material 10-2 is wound for the next circle until the number of winding circles of the flexible packaging material 10-2 reaches the target number of circles.

[0081] It should also be noted that the present application can wrap the disc-like disk 10 - 1 with a single circle of flexible packaging material 10 - 2 .

[0082] It is worth noting that when the first clamping mechanism 4 is specifically set up, the first clamping mechanism 4 can press the flexible packaging material 10-2 close to the head of the flexible packaging material 10-2 against the disc-like 10-1 when the head of the flexible packaging material 10-2 is close to the initial position when the traction mechanism 3 clamps the head of the flexible packaging material 10-2. Then, when the disc seat 1 drives the disc-like 10-1 to rotate, the unwound flexible packaging material 10-2 can cover the head of the flexible packaging material 10-2, thereby avoiding the problem of the head of the flexible packaging material 10-2 being exposed.

[0083] The embodiment of the present application is provided with a disc seat 1 for fixing the disc-like 10-1 and driving the disc-like 10-1 to rotate, and a feeding and withdrawing mechanism 2 for feeding or withdrawing the flexible packaging material 10-2 is provided on one side of the disc seat 1, and a traction mechanism 3 is provided for clamping the head of the flexible packaging material 10-2 and pulling it to rotate circumferentially around the disc-like 10-1, and a first clamping mechanism 4 is provided for making the flexible packaging material 10-2 close to the disc-like 10-1, and the first clamping mechanism 4 and the feeding and withdrawing mechanism 2 are provided along the circumference of the disc seat 1. By using the device for wrapping the disc-like 10-1 with the flexible material disclosed above, the flexible packaging material 10-2 is conveyed to the traction mechanism 3 through the feeding and withdrawing mechanism 2. When the head of the flexible packaging material 10-2 reaches the preset position, the traction mechanism 3 clamps the head of the flexible packaging material 10-2 and pulls the head of the flexible packaging material 10-2 to rotate circumferentially along the disc-like 10-1, so that the flexible packaging material 10-2 is wound around the disc-like 10-1, and cooperates with the first clamping mechanism 4 under the withdrawing mechanism of the feeding and withdrawing mechanism 2 to make the flexible packaging material 10-2 tightly attached to the disc-like 10-1, thereby realizing the edging of the disc-like 10-1 by the flexible packaging material 10-2, and realizing multiple windings of the disc-like 10-1 under the rotation of the disc seat 1. Compared with the existing manual winding, the present application can not only save a lot of manpower, but also avoid the problems of uneven and loose winding.

[0084] Specifically, the feeding and withdrawing mechanism 2 includes: a first driver 21 and a plurality of roller groups;

[0085] The roller assembly includes a first roller and a second roller, wherein the outer wall of the first roller contacts the outer wall of the second roller;

[0086] The first driver 21 is transmission-connected to the first roller and the second roller, and the rotation direction of the first roller is opposite to the rotation direction of the second roller.

[0087] It should be noted that by setting up multiple roller groups, and setting the roller groups into a first roller and a second roller, and the outer wall of the first roller is in contact with the outer wall of the second roller, and the first driver 21 is connected to the first roller and the second roller, and the rotation direction of the first roller is set to be opposite to the rotation direction of the second roller, the flexible packaging material 10-2 passes through the contact surface between the first roller and the second roller, and then when the first driver 21 drives the first roller and the second roller to rotate, the flexible packaging material 10-2 can be transported toward the disc-like 10-1 (i.e., feeding) and transported away from the disc-like 10-1 (i.e., returning).

[0088] Preferably, the first driver 21 is a motor.

[0089] It should be noted that the first driver 21 may be a motor or other driver that can drive the roller assembly to rotate, and those skilled in the art may make a choice according to needs.

[0090] Furthermore, the feeding and withdrawing mechanism 2 further includes: a cutter 23 for cutting the flexible packaging material 10-2;

[0091] The cutter 23 is disposed between adjacent roller groups.

[0092] It should be noted that by arranging a cutter 23 for cutting the flexible packaging material 10-2 between adjacent wheel sets, the flexible packaging material 10-2 can be cut into preset lengths as needed, avoiding waste caused by winding too much flexible packaging material 10-2 around the disc-like disk 10-1.

[0093] It should also be noted that the cutter 23 is a conventional cutting device, which can be a shearing device or a laser cutting device, and those skilled in the art can choose according to their needs.

[0094] Specifically, the traction mechanism 3 includes: a rotating shaft driver 31, a rotating shaft 32, a first lifting mechanism 33, a first clamping claw 34 and a first clamping claw driver 35;

[0095] The upper end of the rotating shaft 32 is in transmission connection with the rotating shaft driver 31;

[0096] The first lifting mechanism 33 is disposed at the lower end of the rotating shaft 32;

[0097] The first clamping jaw 34 is disposed on the first lifting mechanism 33, and the first lifting mechanism 33 is used to drive the first clamping jaw 34 to move up and down;

[0098] The first clamping jaw driver 35 is disposed on the first clamping jaw 34 , and the first clamping jaw driver 35 is used to drive the first clamping jaw 34 to open and close.

[0099] It should be noted that the upper end of the rotating shaft 32 is connected to the rotating shaft driver 31, the first lifting mechanism 33 is arranged at the lower end of the rotating shaft 32, and the first clamping claw 34 is arranged on the first lifting mechanism 33, so that the lifting of the first lifting mechanism 33 can drive the first clamping claw 34 to move up and down. Since the first clamping claw driver 35 is arranged on the first clamping claw 34 and can drive the first clamping claw 34 to open and close, when it is necessary to clamp the head of the flexible packaging material 10-2, the first lifting mechanism 33 drives the first clamping claw 34 to drop downward until the head of the flexible packaging material 10-2 is in the first clamping claw 34. At this time, the first clamping claw 34 is driven to close by the first clamping claw driver 35, thereby achieving the clamping of the flexible packaging material 10-2. 2 head clamping, since the upper end of the rotating shaft 32 is connected to the rotating shaft driver 31, the rotating shaft driver 31 can drive the rotating shaft 32 to rotate, and since the first lifting mechanism 33 is arranged at the lower end of the rotating shaft 32, the first clamping jaw 34 is arranged on the first lifting mechanism 33, therefore, when the rotating shaft driver 31 drives the rotating shaft 32 to rotate, it can drive the first clamping jaw 34 to rotate around the circumference of the disk-like 10-1. When the first clamping jaw 34 needs to be removed, the first clamping jaw 34 can be driven to open by the first clamping jaw driver 35, and then the first clamping jaw 34 can be driven to rise upward by the first lifting mechanism 33, so that when it is not working, it can avoid when installing or removing the disk-like 10-1.

[0100] Preferably, the first lifting mechanism 33 is a cylinder.

[0101] It should be noted that the first lifting mechanism 33 can be a pneumatic cylinder or a hydraulic cylinder, and those skilled in the art can choose according to their needs.

[0102] Furthermore, the device for wrapping the disk-like 10 - 1 with a flexible material further includes: a limiting plate 36 and a second lifting mechanism 37 for driving the rotating shaft driver 31 to move up and down;

[0103] The limiting plate 36 is provided at the lower end of the rotating shaft 32;

[0104] The first lifting mechanism 33 is disposed on the limiting plate 36 .

[0105] It should be noted that by setting a limit plate 36 and a second lifting mechanism 37 for driving the shaft driver 31 to rise and fall, and setting the limit plate 36 at the lower end of the shaft 32, the first lifting mechanism 33 is set on the limit plate 36, and then under the action of the second lifting mechanism 37, the limit plate 36 can be driven to move up and down. When the limit plate 36 moves downward to contact the quasi-disc 10-1, the gap formed by the limit plate 36 and the disc seat 1 can further ensure that the flexible packaging material 10-2 is flatly wrapped around the quasi-disc 10-1 when the disc seat 1 drives the quasi-disc 10-1 to rotate so that the flexible packaging material 10-2 covers the quasi-disc 10-1.

[0106] Specifically, the first pressing mechanism 4 includes: a fixing frame 41, a lateral moving mechanism 42, a fixing plate 43, a rotation driver 44, a first pressing rod 45 and a first rotating wheel 46;

[0114] The first rotating wheel 46 is rotatably disposed on the second end of the first pressing rod 45 .

[0115] It should be noted that the cross bar 41-2 is horizontally arranged on the stand 41-1; and the horizontal moving mechanism 42 for driving the fixed plate 43 to move longitudinally along the cross bar 41-2 is arranged on the cross bar 41-2; the rotation driver 44 is arranged on the fixed plate 43; the first end of the first pressure bar 45 is movably connected to the rotating shaft of the rotation driver 44; the middle section of the first pressure bar 45 is rotatably connected to the fixed plate 43 through a pin, and the first rotating wheel 46 can be rotatably arranged on the second end of the first pressure bar 45, and then when the first clamping mechanism 4 is required to press the flexible packaging material 10-2 tightly against the disc-like 10-1, the fixed plate 43 can be driven to move toward the disc-like 10-1 through the telescopic mechanism, and then the first pressure bar 45 is driven to rotate by the rotation driver 44, so that the first rotating wheel 46 on the first pressure bar 45 presses the flexible packaging material 10-2 tightly against the disc-like 10-1.

[0116] It should also be noted that a first rotating wheel 46 is provided at the second end of the first pressure rod 45. When the first pressing mechanism 4 presses the flexible packaging material 10-2 onto the disc-like 10-1, the friction resistance of the flexible packaging material 10-2 can be reduced, thereby preventing the flexible packaging material 10-2 from breaking during the winding process.

[0117] Preferably, the transverse movement mechanism 42 is composed of a motor, a screw and a slider.

[0127] The lifting plate 6 is located at the discharge port of the feeding and withdrawing mechanism 2;

[0129] The first guide plate 71 and the second guide plate 72 are arranged at a preset angle with the lifting plate 6 to form a feed and return channel for the flexible packaging material 10-2 to pass through, wherein the width of the feed port of the feed and return channel is greater than the width of the discharge port of the feed and return channel.
