Description

Technical Field

[0001] This utility model relates to the field of bottle cap film application equipment, and in particular to a bottle cap film application mechanism with a cutting die that improves film cutting efficiency. Background Technology

[0002] In existing bottle caps, such as those for bottled water (but not limited to bottled water), it is generally necessary to affix appropriate labels to the caps in order to achieve the intended protection and inspection requirements.

[0003] In existing bottle caps, such as those for bottled water (but not limited to bottled water), it is generally necessary to affix appropriate labels to the caps in order to achieve the intended protection and inspection requirements.

[0004] The existing Chinese patent 202420166198.X uses a method of pre-cutting the film and then hot-pressing it to form the label onto the bottle cap.

[0005] The pre-cutting mechanism consists of a fixed die and a moving die that move relative to each other. However, in actual use, it has been found that its processing efficiency is relatively low, far behind the working rhythm of the conveyor belt and the film-applying device. For example, the film-applying device can apply film to 60 pieces per minute in a single-row configuration, while the pre-cutting mechanism of the film-cutting device can only cut 50 pieces per minute, resulting in a difference in processing efficiency.

[0006] Therefore, improving the film cutting efficiency while ensuring stable operation is the key to the design. Utility Model Content

[0007] The main purpose of this invention is to propose a bottle cap film applicator with a cutting die that improves film cutting efficiency. The aim is to improve the cutting mechanism and thus improve the film applicator efficiency. At the same time, the film cutting device has a simple structure and low production cost.

[0008] To achieve the above objectives, this utility model proposes a bottle cap film applicator with a die for improving film cutting efficiency, comprising:

[0009] A material conveying device, comprising a pivotally mounted feeding tray and a receiving tray, the feeding tray and the receiving tray being used for transporting material belts;

[0010] Film cutting device;

[0011] A bottle cap feeding device is used to transport bottle caps. The bottle cap feeding device is provided with an upper cap position, a film-applying position and a lower cap position. The upper cap position is used to transport bottle caps and move them to the film-applying position. The lower cap position is used to unload bottle caps that have been labeled.

[0012] A film-applying device is provided at the film-applying position. When the feeding column moves the bottle cap to the film-applying position, the film-applying device applies the pre-cut label to the bottle cap.

[0013] The film cutting device includes a substrate and a drive seat disposed above the substrate. The drive seat has a cutting part protruding from its wall surface. The drive seat is connected to an active drive device to drive the cutting part to move between a position close to the substrate and a position far away from the substrate.

[0014] The cutting section is provided with a notch recessed along its end.

[0015] The notch is used to cut the material strip into the shape of the label, so that the label can be connected to the material strip.

[0016] In actual operation, the material strip is moved from the feed tray to the receiving tray. Between the base plate and the drive seat, a label of a predetermined shape is pre-cut on the material strip by the cutting part. The label is still connected to the material strip by the setting of the notch (that is, there is a connection structure between the material strip and the pre-cut label), which will not affect the transportation of the material strip, and the pre-cut label will not be deformed.

[0017] When the pre-cut label moves to the film application position, the turntable drives the bottle cap to move below the label through the feeding column. The film application device separates the label from the material strip and fixes it to the bottle cap by hot pressing, ultrasonic welding or pressing.

[0018] The protruding cutting section (the shape of the label) can be set horizontally in one or more sets according to actual needs.

[0019] Compared to existing equipment, its cutting section has lower costs, and since the substrate has a relatively fixed structure, only the die-cutting pad needs to be replaced during assembly. Furthermore, this structure is a consumable component compared to the overall equipment, resulting in lower subsequent maintenance costs.

[0020] Furthermore, its die-cutting efficiency is lower than that of existing cutting tools due to its shorter stroke, resulting in smaller processing gaps and a 5%-25% increase in work efficiency. Attached Figure Description

[0037] like Figures 1 to 5 As shown, a bottle cap film applicator with a die for improving film cutting efficiency includes,

[0038] Material conveying device 1, which includes a pivotally mounted feeding tray 11 and a receiving tray 12, the feeding tray 11 and the receiving tray 12 being used for transporting the material belt 10;

[0039] Film cutting device 2;

[0040] The bottle cap feeding device 3 is used to transport bottle caps. The bottle cap feeding device 3 is provided with an upper cap position 101, a film application position 100 and a lower cap position 102. The upper cap position 101 is used to transport bottle caps and move them to the film application position 100. The lower cap position 102 is used to unload bottle caps with labels.

[0041] The film applicator 4 is located at the film applicator position 100. When the feeding column 32 moves the bottle cap to the film applicator position 100, the film applicator 4 applies the pre-cut label to the bottle cap.

[0042] The film cutting device 2 includes a substrate 21 and a drive seat 22 disposed above the substrate 21. The wall surface of the drive seat 22 is provided with a cutting part 23. The drive seat 22 is connected to an active drive device to drive the cutting part 23 to move between a position close to the substrate 21 and a position far away from the substrate 21.

[0043] The cutting portion 23 is provided with a notch 24 recessed along its end.

[0044] The notch 24 is used to connect the label to the material strip 10 after the label shape is cut out by the material strip 10.

[0045] In actual operation, the material strip 10 is moved from the feeding tray 11 to the receiving tray 12 between the substrate 21 and the drive seat 22, and a label of a predetermined shape is pre-cut on the material strip 10 by the cutting part 23. The label is still connected to the material strip 10 by the setting of the notch 24 (that is, there is a connection structure between the material strip 10 and the pre-cut label), which will not affect the transportation of the material strip 10, and the pre-cut label will not be deformed.

[0046] When the pre-cut label moves to the film application position 100, the turntable 31 drives the bottle cap to move to the position below the label through the feeding column 32. The film application device 4 separates the label from the material strip 10 and fixes it to the bottle cap by hot pressing, ultrasonic welding or pressing.

[0047] The protruding cutting portion 23 (the shape of the label) can be horizontally set in one or more groups according to actual needs.

[0048] Compared to existing equipment, its cutting section 23 has a lower cost, and since the substrate 21 has a relative structure, only the die-cutting pad 28 needs to be replaced during assembly. Furthermore, this structure is a consumable component compared to the overall equipment, resulting in lower subsequent maintenance costs.

[0049] Furthermore, its die-cutting efficiency is lower than that of existing cutting tools due to its shorter stroke, resulting in smaller processing gaps and a 5%-25% increase in work efficiency.

[0050] Specifically, the drive seat 22 has a recessed positioning groove 25 on its wall surface, and the cutting part 23 is fixed by a locking structure after extending into the positioning groove 25.

[0051] In the specific design, the cutting part 23 is preferably detachable to meet the needs of quick disassembly and replacement. The locking structure is preferably fixed by screw or buckle, and the specific shape can be set according to the requirements.

[0052] When using a screw for fixing, a through hole can be provided on the side wall of the drive seat 22, and then the screw passes through the drive seat 22 and is fixed to the cutting part 23.

[0053] In this embodiment of the utility model, the cutting part 23 has a sheet-like structure. Compared with the existing columnar structure, it can be processed in a simpler way. For example, after cutting a predetermined shape, the sheet-like structure is bent into the shape of the label to be punched, and then a blade 26 and a predetermined notch 24 are formed at the end of the cutting part 23.

[0054] Specifically, the end of the cutting part 23 is provided with a blade 26 that tapers from the inside to the outside, wherein the blade 26 is used to separate the material strip 10 from the pre-cut label portion.

[0055] The notches 24 are distributed at intervals or irregularly along the length of the cut portion 23.

[0056] The notch extends towards the drive seat along the height direction of the cut section.

[0057] The notch can be triangular or set according to actual needs.

[0058] In this embodiment of the present invention, the cutting part 23 is provided with a through-hole dividing groove 27 (interface for blade forming processing). The dividing groove 27 can be provided as a notch 24. At the same time, the dividing groove 27 is provided along the height direction of the cutting part 23, which can effectively reduce the cost when processing the cutting part 23. Furthermore, the dividing groove 27 provides the cutting part 23 with a predetermined deformation range, which facilitates its placement in the positioning groove 25.

[0059] Specifically, the drive seat 22 is vertically slidable, and the active drive device is a vertical drive device. The specific method of achieving vertical sliding can be set according to actual needs.

[0060] Of course, the drive seat 22 can also be a circular roller structure, with spaced cutting portions 23 on the outer peripheral wall of the circular roller.

[0061] In this embodiment of the present invention, the upper wall of the substrate 21 is provided with a die-cutting pad 28. The die-cutting pad 28 is supported by a flexible material or is elastically slidably arranged, or the die-cutting pad 28 is provided with a groove that cooperates with the cutting part 23, so as to satisfy the requirement that the cutting part 23 can cut a predetermined shape when moving relative to the cutting part 23.

[0062] A cutting position 103 is provided between the substrate 21 and the drive seat 22. The cutting position 103 and the film application position 100 are either at the same horizontal position or on different horizontal planes.

[0063] Specifically, the bottle cap feeding device 3 includes a pivotally mounted rotating base 31, a plurality of feeding columns 32 spaced apart on the outer periphery of the rotating base 31, and a first driving device 5 for driving the rotating base 31 to rotate. The feeding columns 32 are used for positioning the bottle caps. The top of the rotating base 31 is provided with a film-applying position 100. The rotating base 31 is provided with an upper cap position 101 and a lower cap position 102 on both sides of the film-applying position 100.

[0064] This enables the feeding, hot-pressing, and unloading of bottle caps.

[0065] In this embodiment of the utility model, the film-applying device 4 is an ultrasonic welding device, a hot pressing device, or a pressing device.

[0066] Specifically, the first driving device 5 is a power source 51 and an equal-division drive 52 connected to the power source 51. The equal-division drive 52 is connected to the rotary seat 31 through an angle fine-tuning coupling.

[0067] The power source 51 is a rotary motor, a stepper motor, a closed-loop stepper motor, or a servo motor, which can adjust the processing efficiency between the film application device 4 and the film cutting device 2, reduce efficiency differences, and improve the ease of debugging.

[0068] In this embodiment of the utility model, the main channel is connected to the rotating seat, the feeding column is provided with a branch channel, and the rotating seat is provided with a main channel that cooperates with the branch channel; the branch channel can be connected to the rotating seat vacuum device or the rotating seat negative pressure device or the rotating seat air blowing device or not connected to the rotating seat.

[0069] The upper cover position 101 is provided with a longitudinally arranged upper cover conveyor belt / upper cover support plate. The upper cover conveyor belt / upper cover support plate is located on one side of the turntable 31. The upper cover device 61 is provided on the side of the upper cover conveyor belt / upper cover support plate away from the turntable 31.

[0070] The capping device 61 can push the bottle cap located on the capping conveyor belt / capping tray into the feeding column 32 for fixing;

[0071] The lower cover position 102 is provided with a longitudinally arranged lower cover conveyor belt / lower cover support plate. The lower cover conveyor belt / lower cover support plate is located on the side of the turntable 31 away from the upper cover conveyor belt / upper cover support plate. The lower cover device 62 is provided on the side of the lower cover conveyor belt / lower cover support plate away from the turntable 31.

[0072] The lower cap device 62 can clamp, blow off, or absorb bottle caps located on the lower cap conveyor belt / lower cap tray and transfer them into the lower cap conveyor belt / lower cap tray.

[0073] This structure is existing technology and will not be described in detail here. The use of a longitudinally arranged upper cover conveyor belt / upper cover plate and lower cover conveyor belt / lower cover plate, along with the upper cover device 61 and lower cover device 62, can effectively ensure the stable upper and lower cover of the bottle cap. The structure is simple and compact, which effectively improves the efficiency of upper and lower cover, and thus effectively improves the efficiency of labeling.

[0074] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
