Description

Technical Field

[0001] The invention relates to the technical field of rewinding equipment, and in particular to a label rewinding machine. Background Art

[0002] The label paper reel operation is the last step of the label paper production line. The label rewinder is a special machine for the reel. Its reeling speed is the same as the paper output speed on the previous operation line to ensure the smoothness of the entire production line. However, the reel specifications of the existing label rewinder are relatively fixed and can only match a single size of paper core label shaft. For production lines that often use different paper core label shafts, it is necessary to constantly replace reel shafts of different specifications, which has low production efficiency. Moreover, the standard diameter size of paper core label shafts varies from country to country. Therefore, the reel shaft in China may not be suitable for other countries. Therefore, when the label rewinder is sold to other countries, it is necessary to first understand the standard diameter size of paper core label reel shafts in other countries, and then produce reel shafts corresponding to the standard diameter size. Different countries need to produce reel shafts of different diameter sizes, which is very troublesome.

[0003] In addition, even if the label rewinding machine is only used domestically, there will be errors when the manufacturer produces the paper core label shaft. Therefore, even if a rewinding shaft with the same specifications as the paper core label shaft is used for rewinding, the paper core label shaft may not be firmly fixed or even cannot be fixed.

[0006] Furthermore, the turntable includes a base provided with a first groove and a fixed cover for closing the first groove, and the base is coaxially fixed with the rotating shaft; the main gear and the driving disk are respectively fixed in the first groove, and the first fixing rod passes through the fixed cover.

[0007] Furthermore, the fixing cover is provided with a first through hole matching the fixing shaft, and the fixing shaft passes through the first through hole.

[0008] Furthermore, the fixing cover is provided with arc grooves matching with the first fixing rods when they move, and the number of the arc grooves is the same as the number of the first fixing rods; the first fixing rods pass through the arc grooves.

[0009] Furthermore, a second fixing rod is provided at the center of the fixing cover on a side facing away from the base.

[0010] Furthermore, second grooves for receiving the first fixing rods are provided on the outer sides of the second fixing rods.

[0011] Furthermore, it also includes a driving member, and the other end of the rotating rod is provided with a driving groove, and the driving member matches the driving groove to drive the rotating rod to rotate when an external force acts on the driving member.

[0012] Furthermore, a second through hole is provided on the machine body at a position corresponding to the driving slot, and one end of the driving member can pass through the second through hole to be connected to the driving slot.

[0014] Furthermore, it also includes a second baffle plate for forming a roll-back space with the first baffle plate, and a locking nut is provided on the second baffle plate; the first fixing rod passes through the second baffle plate.

[0015] Compared with the prior art, the present invention has the following advantages: the rotating shaft mechanism in the label rewinder of the present invention includes a turntable, a rotating shaft, disc teeth and a fixing device for fixing the label shaft, wherein the disc teeth include a turning rod and a main gear, and the fixing device includes at least three first fixing rods and a driving disc with the same number as the first fixing rods, and the main gear is meshed with the side of the driving disc; when in use, under the action of an external force rotating the turning rod, the meshing action of the driving disc and the main gear causes the driving disc to rotate, thereby driving the first fixing rods to move toward or away from each other, so that the rewinding shaft formed by multiple first fixing rods can adapt to paper core label shafts of various sizes, and there is no need to replace rewinding shafts of different specifications.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4The embodiment of the present invention provides a label rewinding machine, including a machine body 1 and a rotating shaft mechanism, the rotating shaft mechanism includes a turntable 21, a rotating shaft 22, a disc tooth and a fixing device 24 for fixing the label shaft, the turntable 21 is coaxially fixed with the rotating shaft 22, and the rotating shaft 22 is driven to rotate by a motor (not shown in the figure) provided in the machine body 1; the disc tooth includes a rotating rod 2301 and a main gear 2302, the rotating rod 2301 is fixed in the rotating shaft 22, the main gear 2302 is fixed in the turntable 21, one end of the rotating rod 2301 passes through the center of the turntable 21 and is coaxially fixed with the main gear 2302; the fixing device 24 includes at least three The first fixed rod 2401 and the same number of driving disks 2402 as the first fixed rod 2401, the driving disks 2402 are fixed to the periphery of the main gear 2302 through the fixed shaft 2103 provided in the turntable 21, the side of the driving disk 2402 is provided with a tooth pattern 24021 meshing with the main gear 2302, the first fixed rod 2401 is fixed to the edge of the driving disk 2402 and passes through the turntable 21; when in use, the rotating rod 2301 is rotated by external force, so that the main gear 2302 drives the driving disk 2402 meshing with the main gear 2302 to rotate, so as to drive the first fixed rod 2401 to move toward or away from each other.

[0026] Among them, the tooth pattern 24021 that meshes with the main gear 2302 can be only partially set on the side of the driving disk 2402. When the main gear 2302 and the driving disk 2402 are installed, the same position of multiple driving disks 2402 is meshed with the main gear 2302, so that when the main gear is driven to rotate, the first fixing rods 2401 on the multiple driving disks 2402 can move toward or away from each other.

[0027] A third through hole 24022 is provided at the center of the driving disk 2402, and the fixed shaft 2103 passes through the third through hole 24022 to limit the driving disk 2402. When the main gear 2302 drives the driving disk 2402 to rotate, the driving disk 2402 rotates around the fixed shaft 2103; during the entire rotation process, the center of the driving disk 2402 does not change, and since the first fixed rod 2401 is fixed to the edge of the driving disk 2402, the position of the first fixed rod 2401 changes during the rotation of the driving disk 2402.

[0028] When in use, when the external force drives the rotating rod 2301 in the rotating shaft 22 to rotate, the main gear 2302 will rotate synchronously with the rotating rod 2301, and because the driving disk 2402 is meshed with the main gear 2302, the driving disk 2402 will rotate with the rotation of the rotating rod 2301; and the first fixed rod 2401 fixed on the driving disk 2402 will also rotate synchronously, so that the first fixed rod 2401 moves toward or away from each other, so that the directness of the circumscribed circle formed by multiple first fixed rods 2401 is just adapted to the diameter of the label shaft, so that the label rewinding machine of the present invention can adapt to label shafts of various sizes. Among them, the rotating rod 2301 can be fixed in the rotating shaft 22 through a bearing, so the rotating rod 2301 can move relative to the rotating shaft 22.

[0029] Before using the label rewinding machine of the present invention, first insert the label shaft into the first fixed rod 2401, and then adjust the first fixed rod 2401 so that the multiple first fixed rods 2401 move toward or away from each other, so that the multiple first fixed rods 2401 clamp the label shaft (that is, the circumscribed circle formed by the multiple first fixed rods 2401 just corresponds to the diameter of the label shaft, thereby achieving the effect of clamping the label shaft to prevent the label shaft and the first fixed rods 2401 from moving relative to each other), and then start the motor to drive the rotating shaft 22 to drive the turntable 21 to rotate, so that the label shaft rewinds the label paper.

[0030] The rotating shaft 22 is driven to rotate by a motor. As shown in the figure, a driving roller 5 is provided at the end of the rotating shaft 22, and the driving roller 5 is connected to a roller provided in the machine body 1 through a conveyor belt. When the motor drives the roller to rotate, the roller 5 drives the rotating shaft 22 synchronously, so that the rotating shaft 22 rotates. How to drive the rotating shaft 22 to rotate belongs to the prior art and will not be described here.

[0031] Specifically, Figure 2 and Figure 3 As shown, the rotating disk 21 includes a base 2101 provided with a first groove 21011 and a fixing cover 2102 for closing the first groove 21011. The base 2101 is fixed coaxially with the rotating shaft 22. The main gear 2302 and the driving disk 2402 are respectively fixed in the first groove 21011, and the first fixing rod 2401 passes through the fixing cover 2102. The installation space of the main gear 2302 and the driving disk 2402 is formed by the base 2101 and the fixing cover 2102, which is convenient for installation and maintenance.

[0032] like Figure 1 and Figure 2As shown, the fixed cover 2102 is provided with a first through hole 21021 matching the fixed shaft 2103. The fixed shaft 2103 passes through the first through hole 21021, which is convenient for positioning and limiting the fixed cover 2102, so as to quickly install the fixed cover 2102, and can also prevent the fixed cover 2102 from rotating asynchronously with the first fixed rod 2401.

[0033] The fixing cover 2102 is also provided with an arc groove 21022 that matches the movement of the first fixing rod 2401, and the number of the arc grooves 21022 is the same as the number of the first fixing rod 2401; wherein the first fixing rod 2401 passes through the arc groove 21022. When in use, when the first fixing rod 2401 rotates, the first fixing rod 2401 moves in the arc groove 21022. It can be seen that the arc groove 21022 can limit the first fixing rod 2401.

[0034] Specifically, a second fixing rod 25 is provided at the center of the fixed cover 2102 on the side facing away from the base 2101, which can play a supporting role; wherein the arc grooves 21022 are distributed around the second fixing rod 25. Furthermore, a second groove 2501 for receiving the first fixing rod 2401 is provided on the outer side of the second fixing rod 25, so as to facilitate receiving the second fixing rod 25 and play a protective role. When the diameter of the label shaft is small, such as when it is equivalent to the diameter of the second fixing rod 25, the second fixing rod 25 can play a supporting role. In addition, when it is not necessary to use the label shaft to rewind the label paper, the starting end of the rewound label paper is clamped between the second groove 2501 and the first fixing rod 2401 to play a role in fixing the starting end of the label paper, and then it is convenient to rewind the label paper without the label shaft.

[0035] The invention also includes a first baffle plate, which is fixed to the edge of the fixed cover and is flush with the fixed cover.

[0036] Furthermore, it also includes a second baffle plate for forming a roll-back space with the first baffle plate, and a locking nut is provided on the second baffle plate; the first fixing rod passes through the second baffle plate.

[0037] Furthermore, the first baffle plate 3 is included, and the edge of the fixed cover 2102 is also provided with bolts 6 for fixing with the first baffle plate 3; the first baffle plate 3 is fixed to the edge of the fixed cover 2102 by the bolts 6 and is flush with the fixed cover 2102. When the label paper roll is large, the edge of the label paper roll can be made relatively flat due to the effect of the first baffle plate 3.

[0038] Furthermore, the second baffle plate 7 is used to form a rewinding space with the first baffle plate. The second baffle plate 7 is also provided with an arc groove 21022 that matches the movement of the first fixing rod 2401. The first fixing rod 2401 passes through the arc groove 21022. The second baffle plate is provided with a locking nut 71. The locking nut 71 cooperates with the second fixing rod 25 to ensure that the second baffle plate 7 and the first baffle plate 3 can remain relatively stable under high-speed rewinding.

[0039] When installing the label shaft, first remove the second baffle 7, then insert the label shaft into the first fixing rod 2401 and the second fixing rod 25, then install the second baffle 7, and lock the second baffle 7 with the locking nut 71, and then start the rewinding machine to rewind the label. Since the label paper is limited by the first baffle 3 and the second baffle 7 during the rewinding process, it is ensured that the edge of the label paper can be flat during the rewinding process.

[0040] Furthermore, it also includes a driving member 4, and a driving groove 23011 is provided at the other end of the rotating rod 2301. The driving member 4 matches the driving groove 23011 to drive the rotating rod 2301 to rotate when an external force acts on the driving member 4. The driving groove 23011 is a polygonal structure; when in use, the driving member 4 is inserted into the driving groove 23011, and then the driving member 4 is rotated. Since the driving groove 23011 is a polygonal structure, the rotating rod 2301 will rotate with the rotation of the driving member 4.

[0041] Furthermore, a second through hole 11 is provided at a position corresponding to the driving slot 23011 on the machine body 1, and one end of the driving member 4 can pass through the second through hole 11 to connect with the driving slot 23011. By providing the second through hole 11 on the machine body 1, when it is necessary to adjust the opening size of the first fixing rod 2401, it is not necessary to open the housing 12 of the machine body 1, and the driving member 4 can be inserted into the driving slot 23011 through the second through hole 11 and rotated. The second through hole 11 is provided on the back of the housing 12.

[0042] To summarize, the rotating shaft mechanism in the label rewinder of the present invention includes a turntable 21, a rotating shaft 22, disc teeth and a fixing device 24 for fixing the label shaft, wherein the disc teeth include a rotating rod 2301 and a main gear 2302, and the fixing device 24 includes at least three first fixed rods 2401 and a driving disc 2402 of the same number as the first fixed rods 2401, and the main gear 2302 is meshed with the side of the driving disc 2402; when in use, under the action of an external force rotating the rotating rod 2301, the meshing action of the driving disc 2402 and the main gear 2302 causes the driving disc 2402 to rotate, thereby driving the first fixed rods 2401 to move toward or away from each other, so that the rewinding shaft formed by multiple first fixed rods 2401 can adapt to paper core label shafts of various sizes, with a simple structure and convenient and simple adjustment.

[0043] The label rewinding machine of the present invention can adapt to paper core label shafts of various diameter sizes by adjusting the first fixed rod 2401 to move toward or away from each other. There is no need to replace the rewinding shaft of different specifications, and it can be suitable for various standard paper core label shafts of any country. Moreover, even if there are errors in the diameter sizes of the paper core label shafts generated by various manufacturers, the present invention can also firmly fix the paper core label shaft, and the structure is simple and easy to adjust.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
