Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a linear round bottle or square bottle single-sided or double-sided automatic labeling machine. Background Art

[0002] An automatic labeling machine is a device used to automatically apply labels to products. It's widely used in packaging, production lines, and logistics, improving production efficiency and labeling accuracy. Liquid products like laundry detergent, shower gel, and dishwashing liquid are typically packaged in round or square bottles, with labels affixed to the sides for identification and differentiation. During labeling, due to their large size, the labeling mechanism can only apply labels to a single side. For products requiring double-sided labeling, a double-sided labeling mechanism is typically used to apply labels to both sides simultaneously, improving labeling efficiency.

[0003] When the automatic labeling machine labels the product, it delivers the label to the labeling mechanism through the label feeding mechanism. After the labeled product is transported to the designated position through the conveyor belt, the labeling mechanism uses pressure and other methods to stick the label to the designated position of the product to complete the labeling work. However, when the label feeding mechanism transports the label, since the label roll is usually placed on a rotating disk, the middle fixed rod can only limit the label roll in a large range, causing the label roll to shake slightly when transporting the label, resulting in too fast rotation or jamming, and it is easy for the label roll to break or dislocate, affecting the stability of labeling. Utility Model Content

[0004] Aiming at the problem that the label roll in the prior art is prone to rotating too fast or getting stuck when feeding the label, the utility model provides a linear round bottle and square bottle single-sided and double-sided automatic labeling machine.

[0005] The utility model discloses a linear round bottle and square bottle single-sided and double-sided automatic labeling machine, which includes: a bearing assembly and a fastening assembly, the bearing assembly includes a bearing member and an expansion cylinder, the expansion cylinder is arranged in the middle of one end of the bearing member, and the two are fixedly connected, the bearing member is provided with a ventilation cavity, the bearing member is provided with a ventilation groove connecting the middle of the expansion cylinder with the ventilation cavity, the expansion cylinder is provided with a plurality of gaps along its axial direction, and the diameter of the inner wall of the expansion cylinder gradually decreases from the direction close to the bearing member to the direction away from the bearing member; and the fastening assembly includes a movable member and an expansion block, the movable member is arranged in the ventilation cavity, and the movable member is movably sleeved with the bearing member, and the expansion block is arranged in the middle of the expansion cylinder.

[0006] Preferably, the fastening assembly further includes a bellows, which is disposed between the expansion block and the bearing member, and one end of the bellows is communicated with the ventilation groove.

[0007] Preferably, the fastening assembly further includes an elastic member, which is arranged between the movable member and the elastic member and located in the ventilation cavity.

[0008] Preferably, the supporting member is provided with a vent hole, and the vent hole connects the vent groove with the outside, and is located on a side of the supporting member away from the expansion cylinder.

[0009] Preferably, the bearing assembly further comprises a support member, which is arranged on a side of the bearing member away from the expansion cylinder, and the support member and the bearing member are movably sleeved.

[0010] Preferably, a sealing block is provided at one end of the support member close to the bearing member, and the sealing block is directly opposite to the vent hole, and the two have the same size.

[0015] Compared with the existing technology, the utility model provides a linear round bottle square bottle single-sided and double-sided automatic labeling machine, which has the following beneficial effects:

[0016] 1. This linear round bottle and square bottle single-sided and double-sided automatic labeling machine is equipped with a fastening component. After the label roll is supported by the carrier and the label roll is limited by the expansion cylinder, the pressure of the label roll causes the gas in the vent cavity to push the expansion block along the axial direction of the expansion cylinder along the vent groove. As the diameter of the inner side of the expansion cylinder gradually decreases, the expansion cylinder opens and clamps the middle of the label roll, so that the label roll will not shake, rotate too fast or get stuck, thereby ensuring the stability of the labeling mechanism.

[0017] 2. The linear round bottle and square bottle single-sided and double-sided automatic labeling machine has a vent hole at the bottom of the carrier to connect the outside with the vent groove, and a sealing block is set in the middle of the support. After the carrier and the support are opposite to each other, the sealing block can block the vent hole. After completing the feeding of a roll of label, the carrier and the support can be separated to connect the vent hole to the outside with the vent groove, so that the gas in the vent groove can be discharged outward, so that the expansion block automatically falls back under the action of gravity and the inner inclined surface of the expansion cylinder, so that the expansion cylinder releases the restriction on the label roll, avoiding the need for manual and tedious operations to replace the label roll, ensuring the replacement efficiency of the label roll and improving the labeling efficiency.

[0025] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0026] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0027] Reference Figure 2-Figure 4 , Figure 2 This is a schematic diagram of the structure of the load-bearing component and the fastening component of the utility model; Figure 3 This is another structural diagram of the load-bearing assembly and the fastening assembly of the utility model; Figure 4 The figure is a schematic diagram of the three-dimensional structure of the support assembly of the utility model. A linear round bottle and square bottle single-sided and double-sided automatic labeling machine comprises: a support assembly 1 and a fastening assembly 2, the support assembly 1 comprises a support member 11 and an expansion cylinder 12, the expansion cylinder 12 is arranged in the middle of one end of the support member 11, and the two are fixedly connected, the support member 11 is provided with a ventilation cavity 111, the support member 11 is provided with a ventilation groove 112 connecting the middle of the expansion cylinder 12 with the ventilation cavity 111, the expansion cylinder 12 is provided with a plurality of gaps 121 along its axial direction, and the inner wall diameter of the expansion cylinder 121 gradually decreases from the direction close to the support member 11 to the direction away from the support member 11; and the fastening assembly 2 comprises a movable member 21 and an expansion block 22, the movable member 21 It is arranged in the ventilation cavity 111, and the movable part 21 is movably connected to the supporting part 11. When the movable part 21 moves downward relative to the supporting part 11, the gas in the ventilation cavity 111 can be squeezed to the ventilation groove 112, and when the movable part 21 moves upward relative to the supporting part 11, the gas in the ventilation groove 112 can be drawn into the ventilation cavity 111. The expansion block 22 is arranged in the middle of the expansion cylinder 12. As the air pressure in the ventilation groove 112 changes, the height of the expansion block 22 changes, and cooperates with the gradual reduction of the inner diameter of the expansion cylinder 12, so that the expansion cylinder 12 can expand and contract, thereby clamping or releasing the label roll.

[0028] The straight-line round bottle and square bottle single-sided and double-sided automatic labeling machine is provided with a fastening component 2, so that after the label roll is carried by the carrier 11 and the label roll is limited by the expansion cylinder 12, under the action of the pressure of the label roll, the gas in the ventilation chamber 111 pushes the expansion block 22 along the axial direction of the expansion cylinder 12 along the ventilation groove 112, and under the action of the gradual reduction of the diameter of the inner side of the expansion cylinder 12, the expansion cylinder 12 is opened and clamped in the middle of the label roll, so that the label roll will not shake, resulting in excessive rotation or jamming, thereby ensuring the stability of the labeling mechanism.

[0029] The fastening assembly 2 also includes a bellows 23, which is arranged between the expansion block 22 and the supporting member 11, and one end of the bellows 23 is connected to the ventilation groove 112, and the other end is fixedly connected to the expansion block 22, so that after the air pressure in the ventilation groove 112 is increased, the bellows 23 can be stretched by the air pressure to support the expansion block 22, thereby avoiding gas leakage and causing the expansion tube 12 to fail to expand normally.

[0030] The fastening assembly 2 also includes an elastic member 24, which is arranged between the movable member 21 and the elastic member 24 and is located in the ventilation cavity 111. The elastic member 24 can apply elastic force to the movable member 21 so that the movable member 21 does not contact the bottom surface of the ventilation cavity 111, thereby ensuring that after the movable member 21 loses the pressure of the label roll, it can be automatically ejected by the elastic member 24, so that the air pressure in the ventilation groove 112 and the bellows 23 is reduced, thereby causing the expansion block 22 to automatically fall back, ensuring that a new label roll can be quickly fixed next time.

[0031] The carrier 11 defines a vent hole 113 , which connects the vent groove 112 with the outside and is located on a side of the carrier 11 away from the expansion tube 12 .

[0032] The bearing assembly 1 further includes a support member 13 . The support member 13 is disposed on a side of the bearing member 11 away from the expansion tube 12 , and the support member 13 and the bearing member 11 are movably sleeved.

[0033] A sealing block 131 is provided at one end of the support member 13 close to the carrier 11 . The sealing block 131 is directly opposite to the vent hole 113 , and the two have the same size.

[0034] The straight-line round bottle and square bottle single-sided and double-sided automatic labeling machine has a vent hole 113 at the bottom of the carrier 11 that connects the outside with the vent groove 112, and a sealing block 131 is set in the middle of the support 13, so that after the carrier 11 and the support 13 are opposite to each other, the sealing block 131 can block the vent hole 113, and after completing the feeding of a roll of label, the carrier 11 and the support 13 can be separated to make the vent hole 113 connect the outside with the vent groove 112, so that the gas in the vent groove 112 can be discharged to the outside, so that the expansion block 22 automatically falls back under the action of gravity and the inner inclined surface of the expansion cylinder 13, so that the expansion cylinder 13 releases the restriction on the label roll, avoiding the need for manual and cumbersome operations to replace the label roll, ensuring the replacement efficiency of the label roll and improving the labeling efficiency.

[0035] The sealing block 131 is truncated cone-shaped, so that the gas in the vent groove 112 can be slowly discharged by the sealing block 131 only by separating the carrier 11 by a small gap, further improving the efficiency of changing the label roll. The truncated cone-shaped sealing block 131 can also allow the carrier 11 to rotate around the sealing block 131 without easily separating the carrier 11 and the support member 13, thereby preventing the normal label feeding from occurring.

[0036] The outer circumferential surface of the expansion cylinder 12 is provided with a protrusion 122 along the axial direction, so as to increase the friction between the expansion cylinder 12 and the label roll, thereby improving the stability of the connection between the expansion cylinder 12 and the label roll.
