Description

Technical Field

[0001] The present invention relates to the field of bottle cap film sticking, and particularly to a bottle cap film cutting and sticking mechanism. Background Art

[0002] In existing bottle caps, such as those 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, existing bottle cap film sticking machines, such as Chinese Patent CN201520024823.8, have the following problems from the perspective of the equipment: 1. Their structures are complex, including a punching and heating device and a secondary labeling heating device. Their processing steps require first hot cutting to preliminarily fix the label on the bottle cap, and then the secondary labeling heating device is used to completely fix the label. 2. The label goes through two heating processes, so the processing time for a single cycle is relatively long, and the corresponding energy consumption is also relatively high. Summary of the Invention

[0004] The main object of the present invention is to propose a bottle cap film cutting and sticking mechanism, aiming to improve the existing bottle cap film cutting and sticking mechanism, making its structure simpler and more stable, effectively improving the labeling efficiency, and reducing the power consumption.

[0005] To achieve the above object, the present invention proposes a bottle cap film cutting and sticking mechanism, including:

[0006] A material conveying device, which includes a pivotally arranged feeding tray and a receiving tray, and the feeding tray and the receiving tray are used for transporting the material tape;

[0007] A film cutting device, which is arranged between the feeding tray and the receiving tray and can pre-cut the label on the material tape to match the cap body. The film cutting device includes a fixed knife die and a moving knife die. The fixed knife die is provided with a cutting groove of a predetermined shape, and the moving knife die is adapted to the shape of the cutting groove. The inner peripheral wall of the fixed knife die located in the cutting groove is provided with a first cutting edge, and the outer peripheral wall of the moving knife die is provided with a second cutting edge that cooperates with the first cutting edge. The first cutting edge and / or the second cutting edge is provided with an avoidance position, and the avoidance position enables partial non-contact when the first cutting edge and the second cutting edge are closed;

[0008] A bottle cap feeding device, which includes a pivotally installed rotating seat, a plurality of feeding columns spaced apart from the outer periphery of the rotating seat, and a first driving device for driving the rotating seat to rotate. The feeding columns are used for positioning the bottle caps. The top of the rotating seat is provided with a film sticking position, and the rotating seat is respectively provided with a cap loading position and a cap unloading position on both sides of the film sticking position;

[0009] A film sticking device, which is arranged at the film sticking position. When the feeding column drives the bottle cap to move to the film sticking position, the film sticking device attaches the pre-cut label to the bottle cap.

[0010] In the actual operation of the technical solution of the present invention, the material tape is moved towards the take-up reel through the feed reel. First, the fixed die and the moving die of the film cutting device pre-cut a label of a predetermined shape on the material tape, and through the setting of the avoidance position, the label remains connected to the material tape, which will not affect the transportation of the material tape, and the pre-cut label will not deform. When the pre-cut label moves to the film sticking position, the turntable drives the bottle cap to move to the position below the label through the feeding column, and the film sticking device separates the label from the material tape and fixes it on the bottle cap by means of hot pressing, ultrasonic welding or pressing;

[0011] Advantages of this design: 1. Compared with the prior art, the present application only needs one stamping and one hot pressing to fix the label on the bottle cap. That is, compared with the prior art, the film cutting and film sticking are separately arranged, saving one processing step (i.e., heating and film sticking) of the existing film sticking machine (the traditional film sticking machine has the first heating and film sticking and the second heating and film sticking), saving about 30% of the power consumption; the structure is simpler. From a mechanical perspective, the simpler the mechanical structure, the lower the equipment cost will be;

[0012] 2. Through the cooperation of the film cutting device and the film sticking device, the working time of one processing step of the existing film sticking machine is saved (i.e., two heating and film sticking are not required), and the working efficiency is increased by more than about 30%;

[0013] 3. The key step is to set a notch between the moving die and the fixed die so that the material tape of the pre-cut label can be stably transported between the feed reel and the take-up reel, and then the label can be more quickly and stably attached to the bottle cap.

[0024] As Figures 1 to 6 shown, a bottle cap film cutting and pasting mechanism includes:

[0025] A material conveying device 1, the material conveying device 1 includes a pivotally arranged feeding tray 11 and a receiving tray 12, and the feeding tray 11 and the receiving tray 12 are used for transporting the strip.

[0026] Film cutting device 2, which is arranged between the feeding tray 11 and the receiving tray 12 and can pre-cut the label on the tape 10 to match the cover body. The film cutting device 2 includes a fixed knife die 21 and a moving knife die 22. The fixed knife die 21 is provided with a cutting groove 20 of a predetermined shape, and the moving knife die 22 is adapted to the shape of the cutting groove. The inner peripheral wall of the fixed knife die 21 located at the cutting groove is provided with a first cutting edge 23, and the outer peripheral wall of the moving knife die 22 is provided with a second cutting edge 24 that cooperates with the first cutting edge 23. The first cutting edge 23 and / or the second cutting edge 24 is provided with an avoidance position 3, and the avoidance position 3 enables partial non-contact when the first cutting edge 23 and the second cutting edge 24 are closed;

[0027] Bottle cap feeding device 4, which includes a pivotally mounted turntable 40, a plurality of feeding columns 41 spaced on the outer periphery of the turntable 40, and a first driving device 42 for driving the turntable 40 to rotate. The feeding columns 41 are used for positioning the bottle caps. The top of the turntable 40 is provided with a film sticking position, and the two sides of the turntable 40 located at the film sticking position are respectively provided with a cap covering position and a cap uncovering position;

[0028] Film sticking device 5 (where the film sticking device can be arranged on a vertical moving device, such as a telescopic motor), and the film sticking device 5 is arranged at the film sticking position. When the feeding column 41 drives the bottle cap to move to the film sticking position, the film sticking device 5 attaches the pre-cut label to the bottle cap.

[0029] In actual work, the tape 10 is moved from the feeding tray 11 towards the receiving tray 12. First, the fixed knife die 21 and the moving knife die 22 of the film cutting device 2 pre-cut a label of a predetermined shape on the tape 10 ((driven by a second driving device (not shown) to move the moving knife die towards the fixed knife die and be tangent)), and through the setting of the avoidance position 3, the label remains connected to the tape, which will not affect the transportation of the tape, and the pre-cut label will not be deformed. When the pre-cut label moves to the film sticking position, the turntable 40 drives the bottle cap to move to the position below the label through the feeding column 41, and the film sticking device 5 separates the label from the tape and fixes it to the bottle cap by means of hot pressing or ultrasonic welding or pressing;

[0030] Among them, the structure of the bottle cap feeding device 4 can refer to the applicant's patent CN202021939899.0, which adopts a feeding method of vacuum adsorbing the bottle cap and sets a cap covering position and a cap uncovering position on one side of the film sticking position;

[0031] Advantages of this design:

[0032] 1. Compared with the prior art, the present application only requires one stamping and one hot pressing to fix the label on the bottle cap. That is, compared with the prior art, the film cutting and film pasting are separately arranged, saving one processing step (i.e., heating and pasting) of the existing film pasting machine (the traditional film pasting machine has the first heating and pasting and the second heating and pasting), saving about 30% of the power consumption; the structure is simpler. From a mechanical perspective, the simpler the mechanical structure, the lower the equipment cost will be accordingly.

[0033] 2. Through the cooperation of the film cutting device and the film pasting device, the working time of one processing step of the existing film pasting machine is saved (i.e., two heating and pasting are not required), and the working efficiency is increased by about 30%.

[0034] 3. The key step is to set a notch between the moving knife die and the fixed knife die, so that the tape of the pre-cut label can be stably transported between the feeding tray and the receiving tray, and then the label can be attached to the bottle cap more quickly and stably.

[0035] The film pasting device 5 and the film cutting device 2 are respectively set as separate individuals, and the corresponding equipment height can be reduced, which is convenient for assembly and transportation. That is, the film pasting device 5, the film cutting device 2 and the bottle cap feeding device 4 can be respectively used as separate modules. During assembly, only alignment and reference position debugging are required, effectively saving the transportation cost and the assembly cost. Even when the whole machine is transported, the reduction of its height can make it applicable to different installation sites.

[0036] For the separately provided fixed knife die 21 and moving knife die 22, their cleaning or grinding is simpler. They can be directly sharpened manually, avoiding disassembly. Of course, in order to ensure their processing convenience, the fixed knife die 21 and the moving knife die 22 can also be designed as detachable structures.

[0037] In the prior art, assuming the working time of the two punching and heating structures for the covering cycle of a single label is 3S, then in the present application, the film cutting and film pasting can be completed in 1.5S - 2S, and the production efficiency can be increased by more than 30%. Among them, the film pasting device can also be replaced according to actual needs. For example, an ultrasonic welding device has higher production efficiency, more stable attachment, and can perform precise welding, reducing the deformation of the bottle cap. Of course, for the existing hot pressing head method, although its processing time is longer or similar to that of the ultrasonic welding device, its procurement cost is lower. By improving the selectivity of the equipment, the customer needs can be effectively met, and the market competitiveness can be improved.

[0038] When the feeding column 41 moves to the film pasting position, the upper wall surface of the feeding column 41 is flush with the upper wall surface of the fixed knife die 21, so as to reduce the film pasting error caused by the deformation of the tape. Of course, the fixed knife die may not be flush with the upper end of the feeding column (i.e., not on the same plane), and can also be arranged in a staggered manner. For example, a guide roller can be set to make the tape flush.

[0039] Specifically, the film laminating device is an ultrasonic welding device, a hot pressing and forming device or a pressing device, and the pressing device among them can be applicable to the attachment of labels with adhesives.

[0040] In an embodiment of the present invention, the avoidance position 3 is a first notch 31 provided on the inner peripheral wall of the first cutting edge 23 or a second notch 32 provided on the outer peripheral wall of the second cutting edge 24.

[0041] That is, the avoidance position 3 is separately provided on the first cutting edge 23, the avoidance position 3 is separately provided on the second cutting edge 24, or the avoidance positions 3 are provided on both the first cutting edge 23 and the second cutting edge 24, and the above technical purposes can be achieved.

[0042] Furthermore, the avoidance position 3 is a notch, and the notches are distributed at intervals along the axis or irregularly distributed.

[0043] When the label is in a regular shape, regular distribution is preferred, so that the label can still be connected to the tape, and thus the stable movement of the tape can be realized;

[0044] When the label is in an irregular shape, it can be set according to the connection stability between the label and the tape.

[0045] Among them, the setting of the notch preferably ensures that the label does not fold and does not fall off during movement;

[0046] Of course, the notches can also be distributed in a dot shape, a block shape or a line shape, and can be set according to actual needs.

[0047] In an embodiment of the present invention, the notch penetrates along the height direction of the moving die 22 or the fixed die 21.

[0048] Preferably, the notch is penetrated to facilitate the discharge of cutting waste. Of course, the notch is not penetrated and is a groove 62, and the above effect of connecting the label and the tape can also be achieved.

[0049] Specifically, the moving die 22 has a columnar structure.

[0050] More specifically, the moving die 22 has a non-circular shape structure or a cylindrical shape, the moving die 22 is provided with a convex block 61, and the fixed die 21 is provided with a groove 62 that cooperates with the convex block 61.

[0051] Thereby, the positioning of the moving die 22 is facilitated, displacement is avoided, and the stamping accuracy is improved; through the cooperation of the convex block 61 and the groove 62, the part for tearing the label that protrudes during label forming is also realized, and thus the opening of the bottle cap is facilitated.

[0052] In an embodiment of the present invention, the moving die 22 is a hollow cylinder.

[0053] In one of the embodiments, the film laminating device is provided with a through hole to connect the adsorption device or the blowing device, so as to realize the adsorption and fixation of the label or blow the label to the position attached to the bottle cap.

[0054] Specifically, a horizontally recessed limiting groove is provided in the middle of the moving cutter die 22, so that the moving cutter die 22 can be accurately installed on the positioning plate or the positioning structure, reducing the cutting error.

[0055] In the embodiment of the present invention, the first driving device 42 is an equal division driver, and the equal division driver is connected to the turntable 40 through an angle fine adjustment coupling 43; among them, the equal division driver can adopt the cooperation of a servo motor or a rotary motor and a motor, so as to realize that the rotation angle of the turntable 40 is the same each time.

[0056] Specifically, the feeding column 41 is provided with a branch channel, and the turntable 40 is provided with a main channel 71 that cooperates with the branch channel. Among them, the branch channel 72 can be connected to a vacuum device or a blowing device.

[0057] In the embodiment of the present invention, the branch channel can be connected to a vacuum device or a blowing device. For example, a negative pressure valve is provided in the branch channel. When the bottle cap is located on the feeding column 41, negative pressure is applied to fix the bottle cap. After the film is laminated, the bottle cap is unloaded by blowing.

[0058] Furthermore, through holes 81 are provided on the outer peripheral wall of the feeding column 41. The through holes are connected to the branch channels, and rubber plugs 82 can be installed in the through holes. In order to simplify the loading and unloading of the bottle caps, an external suction structure or blowing structure can be adopted.

[0059] The material tape can process 2 or more labels at the same time each time, and the corresponding bottle caps can also be attached with two labels each time. Of course, it is not limited to 2, and the quantity can be set according to actual needs.

[0060] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
