Description

Technical Field

[0001] This utility model relates to the field of bottle cap film application equipment, and in particular to a chain-type bottle cap film application mechanism. 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] Existing bottle cap laminating equipment generally uses a vacuum positioning device to realize the feeding, laminating, and unloading of bottle caps. The vacuum positioning device can be referenced in Chinese Patent 202021939899.0. Although it can achieve a small size, in terms of the actual cost of the bottle cap conveying mechanism, this equipment consists of multiple sets of vacuum systems working together. Therefore, it has high requirements for processing accuracy and equipment operation stability, resulting in a high overall cost of bottle cap laminating equipment and affecting the market competitiveness of the equipment. Utility Model Content

[0005] The main objective of this invention is to propose a chain-type bottle cap film-applying mechanism that separates the die-cutting position (including punching / rolling / die-cutting) and the film-applying position into two workstations. Through a chain-type bottle cap conveying structure, the mechanism realizes the feeding, film application, and unloading of bottle caps. Its structure is simple, and its operating and maintenance costs are low, resulting in a lower overall equipment price. It improves production efficiency by more than 80% compared to existing equipment on the market, thereby effectively increasing market share.

[0006] To achieve the above objectives, this utility model proposes a chain-type bottle cap film applicator, comprising:

[0007] frame;

[0008] 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 the material strip, with the die-cutting position and the film-applying position on the frame being separated into two workstations;

[0009] A bottle cap transport device includes a drive roller and a driven roller spaced apart, and a conveyor chain disposed around the outer periphery of the drive roller and the driven roller. The drive roller and the driven roller are respectively mounted at both ends of a frame, and at least two conveyor chains are arranged vertically in parallel and synchronously.

[0010] The conveyor chain is provided with equally spaced base plates and bottle cap positioning posts on the base plates. The positioning posts are used to position the bottle caps. The base plates are synchronously and equally spaced along the chain's moving direction and are perpendicular to the chain's moving direction.

[0011] A first driving device is connected to a drive roller and is used to drive the conveyor chain to move cyclically. The conveyor chain has an upper cover position, a film application position and a lower cover position along its length.

[0012] A film cutting device is located at the die-cutting position, between the feeding tray and the receiving tray, and can pre-cut the material strip into a label shape that matches the cap while still being connected to the material strip;

[0013] A film-applying device is provided at the film-applying position. When the substrate and the bottle cap positioning post on the substrate move the bottle cap to the film-applying position, the film-applying device applies the pre-cut label to the bottle cap.

[0014] In actual work, the material belt is moved from the feeding tray to the receiving tray. First, the film cutting device pre-cuts labels of a predetermined shape on the material belt. By setting the avoidance position, the label is still connected to the material belt and will not affect the transportation of the material belt. The pre-cut label will not be deformed.

[0015] The bottle cap transport device is equipped with an upper cap device at the upper cap position and a lower cap device at the lower cap position. The upper cap device is used to place the bottle cap on the bottle cap positioning post. When the bottle cap is moved to the film application position by the movement of the conveyor belt, the bottle cap transport device moves the bottle cap to the position below the label. The film application device separates the label from the material tape and fixes it to the bottle cap by hot pressing, ultrasonic welding or pressing. This realizes the automated film application of the bottle cap.

[0016] The use of a chain-type bottle cap transport device can reduce the width and length of the bottle cap film applicator. Its simple structure eliminates the need for precise control of the vacuum device, thus achieving automatic loading and unloading of bottle caps and effectively reducing the overall production cost. In addition, the chain-type bottle cap transport device has more linear cycle control, thereby reducing the defect rate. Attached Figure Description

[0039] like Figures 1 to 9 As shown, a chain-type bottle cap film applicator includes:

[0040] Rack 1;

[0041] Material conveying device 2, which includes a pivotally mounted feeding tray 21 and a receiving tray 22, the feeding tray 21 and the receiving tray 22 being used for transporting the material belt 20;

[0042] The bottle cap transport device 3 includes a drive roller 31 and a driven roller 32 spaced apart, and a conveyor chain 33 located around the drive roller 31 and the driven roller 32. The drive roller 31 and the driven roller 32 are respectively installed at both ends of the frame 1. The conveyor chain 33 is vertically arranged. The material conveying device 2, the film cutting device 4, and the film applying device 9 can be located above the frame 1. The two ends of the frame 1 are provided with an upper cover device and a lower cover device.

[0043] The conveyor chain 33 is provided with spaced clamping posts 35, which are used to position the bottle cap;

[0044] The first driving device 81 is connected to the active roller 31 and is used to drive the conveyor chain 33 to move cyclically. The conveyor chain 33 is provided with an upper cover position 11, a film application position 13 and a lower cover position 12 along its length direction.

[0045] The film cutting device 4 is located at the die position and is positioned between the feeding tray 21 and the receiving tray 22. It can pre-cut the label shape that matches the cover body on the material strip 20 and is still connected to the material strip 20.

[0046] The film applicator 9 is located at the film applicator position 13. When the clamping column 35 moves the bottle cap to the film applicator position 13, the film applicator 9 applies the pre-cut label to the bottle cap.

[0047] In actual work, the material belt 20 is moved from the feeding tray 21 to the receiving tray 22. First, the film cutting device 4 pre-cuts a label of a predetermined shape on the material belt 20. By setting the avoidance position, the label is still connected to the material belt 20, which will not affect the transportation of the material belt 20, and the pre-cut label will not be deformed.

[0048] The bottle cap transport device 3 has an upper cap position 11 equipped with an upper cap device and a lower cap position 12 equipped with a lower cap device. The upper cap device is used to place the bottle cap on the clamping column 35. When the bottle cap is moved to the film application position 13 by the movement of the conveyor belt, the bottle cap transport device 3 moves the bottle cap to the position below the label. The film application device 9 (which is moved by the vertical moving device) separates the label from the material strip 20 and fixes it to the bottle cap by hot pressing, ultrasonic welding or pressing. Thus, the automated film application of the bottle cap is realized.

[0049] The use of a chain-type bottle cap transport device 3 can reduce the width and length of the bottle cap film applicator. At the same time, its simple structure eliminates the need for precise control of the vacuum device, thereby achieving automatic loading and unloading of bottle caps and effectively reducing the overall production cost. In addition, the chain-type bottle cap transport device 3 has a more linear cycle control, which reduces the defect rate of processing.

[0050] Specifically, the end of the clamping post 35 is provided with a guide angle, which makes it easier for the bottle cap to be clamped on the clamping post 35.

[0051] In this embodiment of the utility model, the clamping post 35 is arranged in a stepped shape in the height direction, wherein the stepped structure can facilitate the insertion of the bottle cap while reducing wear on the inner wall of the bottle cap.

[0052] Specifically, the clamping column 35 is used to place the bottle cap through a vacuum device, an elastic structure, or a mechanical mechanism. The elastic structure can be an elastic skin, a spring, or other structure, and the mechanical structure can be a robotic arm, a gripper, or a sliding structure, thereby achieving the limitation of the bottle cap.

[0053] Specifically, the first driving device 81 is a rotary motor or a mechanical driving mechanism (such as pneumatic drive, motor-driven divider drive), wherein the rotary motor can achieve intermittent pauses, thereby realizing the hot pressing of the label onto the bottle cap;

[0054] The conveyor chain 33 is provided with spaced base plates 34, and the clamping posts 35 are provided on the base plates 34;

[0055] The inner circumference of the conveyor chain 33 is provided with a support plate, which is located on the top wall of the inner cavity of the conveyor chain 33.

[0056] The mounting base 34 is used to install the clamping column 35, which makes the installation and positioning of the conveyor chain 33 more stable. At the same time, a support plate is set in the inner circumference of the conveyor chain 33, which enables the hot pressing of the film applicator 9 and provides support.

[0057] Specifically, the film-applying device 9 is an ultrasonic welding device, a hot-press forming device, or a pressing device, which can separate the connection between the label and the material strip 20 and simultaneously attach the label to the bottle cap.

[0058] In the first embodiment, the film cutting device 4 includes a fixed die 51 and a movable die 52, and the frame 1 is provided with a second driving device 82 for driving the movable die 52 to reciprocate vertically.

[0059] The fixed die 51 has a pre-shaped groove, and the movable die 52 is adapted to the shape of the groove. The fixed die 51 has a first cutting edge 501 on the inner peripheral wall of the groove, and the movable die 52 has a second cutting edge 502 on the outer peripheral wall that cooperates with the first cutting edge 501. The first cutting edge 501 and / or the second cutting edge 502 have clearance positions, which prevent the first cutting edge 501 and the second cutting edge 502 from contacting each other when the die is closed. When the label is a regular shape, it is preferred to have a regular distribution so that the label can still be connected to the material strip 20, thereby achieving stable movement of the material strip 20. When the label is an irregular shape, it can be set according to the stability of the connection between the label and the material strip 20. The notch 41 is preferably set so that the label does not fold or fall off during movement. Of course, the notch 41 can also be distributed in a dotted, block, or line shape, depending on the actual needs. One or both of the first and second cutting edges can be used.

[0060] In the second embodiment, the film cutting device 4 includes a pivotally mounted main roller 61 and a driven roller 62, both of which are cylindrical. The film cutting device 4 is provided with a third driving device 83 for driving the main roller 61 and / or the driven roller 62 to rotate.

[0061] The main roller 61 or the driven roller 62 is provided with a protruding cutting part 40. The cutting part 40 is provided with a plurality of notches 41. The notches 41 are used to connect the label to the material strip 20 after the label is cut out by the material strip 20.

[0062] In actual operation, the material strip 20 is moved from the feeding tray 21 towards the receiving tray 22. The material strip 20 passes between the rotating main roller 61 and the driven roller 62, and a pre-cut label of a predetermined shape is pre-cut on the material strip 20 by the cutting part 40. The notch 41 ensures that the label remains connected to the material strip 20 (i.e., there is a connecting structure between the material strip 20 and the pre-cut label), which does not affect the transportation of the material strip 20, and the pre-cut label will not deform. When the pre-cut label moves to the film application position 13, the rotating seat drives the bottle cap to move to the position below the label through the feeding column. The second driving device 82 drives the rotation of the main roller 61 and the driven roller 62, which can drive the material strip 20 to be transported at the same time, and the label can be pre-cut by the cutting part 40.

[0063] The efficiency of film cutting and film application is further improved. Compared with the film cutting device 4 of the first embodiment, the efficiency of the film cutting device 4 of the second embodiment is effectively improved.

[0064] In the third embodiment,

[0065] The film cutting device 4 includes a base 71 and a drive seat 72 disposed above the base 71. The wall surface of the drive seat 72 is provided with a cutting part 40. The drive seat 72 is connected to the fourth drive device 84 to drive the cutting part 40 to move between a position close to the base 71 and a position away from the base 71.

[0066] The cutting portion 40 is provided with a notch 41 recessed along its end.

[0067] The notch 41 is used to connect the label to the material strip 20 after the label shape is cut out of the material strip 20.

[0068] The protruding cutting section 40 (in the shape of the label) can be horizontally arranged in one or more sets as needed. Compared with the first and second embodiments, the cutting section 40 in the third embodiment has a lower cost. Since the base 71 is a relatively fixed structure, only the die-cutting pad 73 needs to be replaced during assembly. Compared to other consumable structures, this structure has lower subsequent maintenance costs.

[0069] The third drive unit 83 and the fourth drive unit 84 can be rotary motors.

[0070] Specifically, the upper wall of the substrate 34 is provided with a die-cutting pad 73. The die-cutting pad 73 is supported by a flexible or rigid material or is elastically slidable, or the die-cutting pad 73 is provided with a groove that cooperates with the cutting part 40, so as to meet the requirement of cutting a predetermined shape when the cutting part 40 moves relative to the cutting part. At the same time, the die-cutting pad 73 is also convenient for replacement and reduces the wear of the cutting part 40.

[0071] In actual design, the cutting part 40 can be radially arranged, axially arranged, or recessed along the Z-axis direction, thereby forming a gap to form a connection between the material strip 20 and the label.

[0072] The substrate is provided with at least one clamping post. Specifically, the clamping posts can be arranged in one row or in multiple rows.

[0073] 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.
