Description

Technical Field

[0001] The utility model relates to the field of bottle cap film pasting equipment, and particularly relates to a bottle cap film pasting machine with a multi-row structure. Background Art

[0002] For existing bottle caps, such as the bottle caps of barreled water (certainly not limited to barreled water), corresponding labels generally need to be attached to the bottle caps to meet the requirements of predetermined protection and inspection.

[0003] However, for existing bottle cap film pasting machines, such as Chinese Patent CN201520024823.8,

[0004] The prior art has the following problems: 1. It only has a single-row material column, so its processing efficiency is affected, which is also a waste of production capacity; 2. The existing heating device generally uses a direct pressing method to thermally press and bond the label to the bottle cap. Therefore, in actual inspection, there will also be damage caused by the label pressing strength being greater than the predetermined value, affecting the production qualification rate. Summary of the Utility Model

[0005] The main purpose of the utility model is to propose a bottle cap film pasting machine with a multi-row structure, aiming to improve the existing feeding structure to improve the film pasting efficiency, and at the same time, elastically press the heating device and the label to ensure the bonding strength and improve the production qualification rate.

[0006] To achieve the above purpose, the utility model proposes a bottle cap film pasting machine with a multi-row structure, including

[0007] A bottle cap feeding device, which is used for conveying bottle caps. The bottle cap feeding device is provided with a cap loading position, a film pasting position, and a cap unloading position. The cap loading position is used for conveying bottle caps and moving them to the film pasting position, and the cap unloading position is used for unloading the bottle caps with labels attached.

[0008] The bottle cap feeding device includes a pivotally mounted turntable, a plurality of groups of feeding columns arrayed along the outer peripheral wall of the turntable, and a first driving device for driving the turntable to rotate. Each group of feeding columns has at least two rows, and the feeding columns are used for positioning bottle caps. The film pasting position is located above or at the rear side of the turntable.

[0009] A heating device, which is arranged at the film pasting position. The heating device includes a frame, sliding rods arranged on both sides of the frame, a sliding seat slidably mounted on the sliding rods, and heating columns arranged on the sliding seat. The end face of the heating columns is arranged opposite to the feeding columns. The heating columns have at least two rows (certainly, it can also be three rows or four rows, and preferably two rows are implemented, which can not only ensure the structural compactness but also ensure the working efficiency).

[0010] A telescopic device is provided at a position of the frame away from the sliding seat, and an elastic member is provided between the driving end of the telescopic device and the sliding seat.

[0011] In the actual design, due to the structure of the double-row feeding columns, two rows of bottle caps can be labeled simultaneously during actual processing. First, the bottle cap conveying device arranges two rows of bottle caps and then conveys them to the two rows of feeding columns. Then, the material device pre-cuts or directly attaches two rows of labels to the bottle caps. Then, through the heating columns of the heating device, the labels are stably attached to the bottle caps. When the heating columns are actually in contact with the labels, the heating columns apply pressure to the bottle caps. However, due to the action of the elastic member, rigid contact between the heating columns and the bottle caps is avoided, the pressure between the bottle caps and the heating columns is reduced, thereby ensuring the stable attachment of the labels and improving the qualified rate of label attachment.

[0030] As Figures 1 to 7 shown, a bottle cap film pasting machine with a multi-row structure includes

[0031] a bottle cap feeding device 1, the bottle cap feeding device 1 is used for conveying bottle caps, the bottle cap feeding device 1 is provided with a cap loading position 101, a film pasting position 103, and a cap unloading position 102. The cap loading position 101 is used for conveying bottle caps and moving them to the film pasting position 103, and the cap unloading position 102 is used for unloading the bottle caps with labels pasted.

[0032] The bottle cap feeding device 1 includes a pivotally mounted turntable 11, multiple groups of feeding columns 12 arrayed along the outer peripheral wall of the turntable 11, and a first driving device 13 for driving the rotation of the turntable 11. Each group of feeding columns 12 has at least two rows, and the feeding columns 12 are used for positioning the bottle caps; the film sticking position 103 is located above or at the rear side of the turntable 11;

[0033] A heating device 2, the heating device 2 is arranged at the film sticking position 103. The heating device 2 includes a frame 20, sliding rods 21 arranged on both sides of the frame 20, a sliding seat 22 slidably mounted on the sliding rods 21, and heating columns arranged on the sliding seat 22. The end face of the heating column is arranged opposite to the feeding column 12. The heating column has at least two rows (of course, it can also be three rows, four rows, and the preferred implementation is two rows, which can not only ensure the structural compactness but also ensure the working efficiency),

[0034] A telescopic device 24 is arranged at a position of the frame 20 away from the sliding seat 22, and an elastic member is arranged between the driving end of the telescopic device 24 and the sliding seat 22.

[0035] In the actual design, due to the structure of the double-row feeding columns 12, two rows of bottle caps can be pasted with labels simultaneously during actual processing. First, the bottle cap conveying device arranges two rows of bottle caps and then conveys them to the two rows of feeding columns 12. Then, the material device pre-cuts or directly attaches two rows of labels to the bottle caps, and then through the heating columns of the heating device 2, the labels are stably attached to the bottle caps. When the heating column is actually in contact with the label, the heating column applies pressure to the bottle cap, but due to the action of the elastic member, the rigid contact between the heating column and the bottle cap is avoided, the pressure between the bottle cap and the heating column is reduced, and thus the stable attachment of the label is ensured, and the qualified rate of label pasting is improved.

[0036] Specifically, horizontal planes 14 are arrayed on the outer peripheral wall of the turntable 11, and the two rows of feeding columns 12 are arranged at intervals on the horizontal planes 14. This facilitates the positioning and installation of the turntable 11; in a preferred embodiment, there are eight horizontal planes 14, thereby realizing the intermittent processing and waiting for feeding, processing, and discharging, effectively improving the production efficiency.

[0037] Specifically, the telescopic device 24 is a telescopic motor or a telescopic cylinder,

[0038] A positioning seat 23 is arranged at the driving end of the telescopic device 24. The sliding seat 22 extends towards the positioning seat 23 with guide rods 25 corresponding to the heating columns one by one. The rear ends of the guide rods 25 are slidably mounted on the positioning seat 23, and the elastic member is arranged on the guide rods 25.

[0039] Specifically, the elastic member is a hydraulic rod or a top spring 26 sleeved on the guide rod 25. The corresponding elastic members ensure that the forces between each heating column and the bottle cap are consistent, avoiding damage caused by uneven local stress.

[0040] In actual design, when the film pasting position 103 is set at the upper position, the film cutting device of CN202420283204.X is adopted. At this time, the heating device 2 is for one-time heating and labeling (such as Figure 7 )

[0041] When the film pasting position 103 is set at the rear side position, such as Figure 6 , when the punching and heating device 2 of CN201520024823.8 is adopted, the heating device 2 of the present application is for secondary heating and labeling;

[0042] Effectively ensures the stable adhesion of the label.

[0043] Specifically, an upper cover device 3 is provided at the upper cover position 101, and the upper cover device 3 is used to convey the bottle cap to the turntable 11;

[0044] The upper cover device 3 includes a first bottle cap channel 31 and a second bottle cap channel 32 that are spaced apart in the height direction,

[0045] The front ends of the first bottle cap channel 31 and the second bottle cap channel 32 are respectively provided with a first opening and a second opening;

[0046] At the upper position and the lower position of the upper cover device 3, a first telescopic motor 41 and a second telescopic motor are respectively provided. The first telescopic motor 41 and the second telescopic motor 42 are respectively provided with a first baffle 33 and a second baffle 34 that face each other,

[0047] The first baffle is used to block or open the first opening;

[0048] The second baffle is used to block or open the second opening.

[0049] Through the settings of the first bottle cap channel 31 and the second bottle cap channel 32, two rows of bottle caps are conveyed to two rows of feeding columns 12. At the same time, the staggered settings of the first telescopic motor 41 and the second telescopic motor 42 effectively ensure the compactness of the structure.

[0050] Specifically, at positions of the first bottle cap channel 31 and the second bottle cap channel 32 far from the first opening and the second opening, a first push plate 35 and a second push plate 36 are respectively provided,

[0051] The first push plate 35 and the second push plate 36 are respectively connected with a third telescopic motor 43 and a fourth telescopic motor 44. When the feeding column 12 and the bottle cap are oppositely arranged, the first baffle and the second baffle open the corresponding openings, and then the first push plate 35 and the second push plate 36 respectively push the bottle caps into the feeding columns 12 of the corresponding rows. Then, the adsorption device arranged inside the feeding column 12 adsorbs and fixes the bottle caps, and then rotates to the next film pasting position 103.

[0052] Specifically, when there are two rows of feeding columns 12, the end walls of the two rows of feeding columns 12 are arranged in parallel.

[0053] Specifically, the lower cover position 102 is provided with a lower cover device 5, and the lower cover device 5 is used to move the bottle caps from the feeding column 12 to the material tank;
