Description

Technical Field

[0001] This utility model relates to the field of trademark cutting technology, and more specifically to a trademark cutting and transfer combination drum. Background Technology

[0002] Labeling equipment is commonly used in automated beverage packaging production lines. Film labeling equipment has a core mechanism called the "labeling station," which performs a label transfer function. The typical process involves pulling, conveying, cutting, and transferring sheet-like film labels to a predetermined length according to pre-defined requirements, then transferring them to the rotating drum surface. The beverage container then moves or rotates, and the labeling action is performed. Traditional labeling stations use separate cutting and transfer drums for label cutting and transfer. To achieve a smooth and accurate transfer, the rotation speed and diameter of both drums must be matched, and there should be no slippage at the contact point between the two drums, maintaining pure rolling. The label transfer on the transfer drum surface is slip-free. The length of the label that can be transferred (positively correlated with the diameter of the beverage container) is significantly limited by the labeling station layout. Furthermore, the cutting drum also needs to be made as a conversion component (or replaceable component) to adapt to different containers (according to product type), resulting in costs and limiting the applicable container diameter. Utility Model Content

[0003] 1. Technical problem to be solved by the utility model

[0004] To address the technical problem of limited applicable container diameter during trademark cutting in existing automated beverage packaging production lines, this invention provides a trademark cutting and transfer combination drum. By combining the functions of the cutting drum and the transfer drum into a single combined execution drum, the applicable range of trademark length can be expanded, thereby increasing the applicable range of container diameter.

[0005] 2. Technical Solution

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A trademark slitting and transfer assembly drum includes an annular assembly drum body, a trademark head transfer block and a trademark tail transfer block embedded in the annular surface of the assembly drum body, and a slitting device fixedly connected to the inner bottom plate of the assembly drum body. Vacuum suction holes are provided on the outer surfaces of the assembly drum body, the trademark head transfer block, and the trademark tail transfer block. A slitting gap is reserved in the middle of the trademark tail transfer block. The slitting device includes a blade, a blade seat, a guide seat, and a guide block. The blade seat has an internal cavity, which is generally an L-shaped channel inside the blade seat. The guide seat and... The cutting tool slides vertically and horizontally within the cavity; the bottom of the guide seat is connected to the guide block, and the rear end of the cutting tool is connected to the guide block, with the front cutting edge protruding from the side of the cutting tool seat; as the guide block slides up and down with the guide seat, it pulls and pushes the cutting tool to slide left and right, extending and retracting within the cutting gap, thus achieving a fixed-frequency cutting of trademarks by the cutting tool. The applicable range of trademark length is increased, which means the applicable range of container diameter is increased. The functions of the cutting drum and the transfer drum are combined into one combined execution drum, reducing the variety of equipment replacement parts, improving production efficiency, and significantly reducing costs.

[0008] The further trademark cutting and transfer combination drum, the annular spacing between the trademark head transfer block and the trademark tail transfer block is the trademark application length transferred to the container. This length can be achieved by changing the combination drum body to adjust the annular spacing between the trademark head transfer block and the trademark tail transfer block, or it can be achieved by adjusting the rotation speed of the combination drum body and the frequency of the guide block sliding up and down. The applicable range of trademark length is further expanded and achieved by multiple technical means.

[0009] Further, a trademark slitting and transfer assembly drum is formed. A vacuum distribution plate is opened between the assembly drum body and its base plate, forming a vacuum sealing cavity that communicates with the vacuum adsorption hole. A vacuum pump is connected to the vacuum sealing cavity to ensure a continuous negative pressure in the vacuum adsorption hole.

[0010] The further trademark cutting and transfer combination drum has a drive shaft in the middle of the drum body, which is connected to a power output shaft to realize the rotation of the drum body. The guide seat is fixedly connected to the guide block through a vertical rod. The guide block is pressed against the vertical potential energy spring pressure rod assembly. The vertical potential energy spring pressure rod assembly drives the vertical rod to reset upward in the cavity. The vertical rod guides the lifting and lowering to improve the pushing accuracy of the blade, thereby improving the accuracy of cutting the trademark.

[0011] The further trademark cutting and transfer combination drum has an upward inclined structure on the front bottom surface of the guide block, which presses against the push bearing assembly. The rear end of the blade is connected to the push bearing assembly. The push bearing assembly presses against the transverse potential energy spring pressure rod assembly, which drives the blade to reset to the left. By pushing the blade through the bearing assembly, the pushing accuracy of the blade can be further improved.

[0012] The further trademark slitting and transfer assembly drum has a fixed pulley system vertically fixed on the cavity wall where the blade is fixed. The fixed part of the blade is tumblingly connected to the fixed pulley system, providing sliding guidance for the translation of the blade to reduce the friction force of the bearing assembly pushing the blade.

[0013] The further trademark slitting and transfer assembly drum has a guide block rear end rotatably connected to a movable pulley. The movable pulley drives the guide block to roll and connect to the cavity wall, providing sliding guidance for the lifting and lowering of the guide block, so as to reduce the friction force of the vertical rod pushing the guide block.

[0014] The further trademark slitting and transfer assembly drum has a buffer pad fixed on the cavity wall where the upper end face of the guide block is located, in order to buffer the impact force received by the guide block, avoid the blade body from receiving significant vibration, reduce noise, and achieve both the accuracy and smoothness of blade movement.

[0015] The further trademark cutting and transfer assembly drum has a roller connected to the top of the vertical rod. When an external force is applied to the roller, the roller moves downward, driving the vertical rod to move downward as a guide.

[0016] The further trademark cutting and transfer combination drum has an inverted L-shaped blade with a serrated front end. It is sharp and has a fast advance speed. When the film encounters the blade, it is in a taut state due to the force of the front and rear components (traction position and combination drum), making it easy to cut the required kerf. In the instant the combination drum continues to rotate, the film breaks instantly under the combined force of the front and rear components.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] (1) The trademark cutting and transfer combination drum of this utility model is the core component of the trademark station. It completes the cutting and transfer of trademarks, reduces the number of components in the trademark station, and is applicable to cases with large trademark size and large container diameter. Replacement parts are more economical. It can also realize the fixed frequency cutting of trademarks by the blade, which increases the applicable range of trademark length, that is, the applicable range of container diameter. The functions of the cutting drum and the transfer drum are combined into one combination execution drum, which reduces the variety of equipment replacement parts, improves production efficiency, and significantly reduces costs.

[0020] (2) The trademark slitting and transfer combination drum of this utility model has a precise guiding mechanism applied to the lifting and horizontal pushing directions that require precise movement in the cavity. After the adjustment is completed, the movement of the cutting tool will always be in a precise state, so that the working accuracy of the slitting tool remains stable and continuously accurate.

[0021] (3) The trademark cutting and transfer combination drum of this utility model has a buffer pad that can buffer the impact force received by the guide block, isolate the impact force on the blade body, avoid the blade body from receiving obvious vibration, reduce noise, and achieve the effect of satisfying both the accuracy of blade movement and the smoothness of blade movement.

Detailed Implementation

[0031] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0032] Example 1

[0033] The trademark slitting and transfer assembly drum in this embodiment, such as Figure 1 ,2 As shown in Figure 3, the device includes an annular combined drum body 1, a trademark head transfer block 12 and a trademark tail transfer block 16 embedded in the annular surface of the combined drum body 1, and a cutting device 2 fixedly connected to the inner bottom plate 10 of the combined drum body 1. Vacuum adsorption holes 11 are provided on the outer surfaces of the combined drum body 1, the trademark head transfer block 12 and the trademark tail transfer block 16.

[0034] A cutting gap 14 is reserved in the middle of the trademark tail transfer block 16; such as Figure 4 , 5 As shown in Figures 6 and 7, the slitting device 2 includes a blade 20, a blade holder 22, a guide seat 21, and a guide block 25. The blade holder 22 has a cavity inside, which is generally an L-shaped channel inside the blade holder 22. The guide seat 21 and the blade 20 are slidably connected to the cavity in the upper and lower and left and right directions, respectively. The bottom of the guide seat 21 is connected to the guide block 25, and the rear end of the blade 20 is connected to the guide block 25. The front cutting end of the blade 20 protrudes from the side of the blade holder 22. When the guide block 25 slides up and down with the guide seat 21, it pulls and pushes the blade 20 to slide left and right, extending and retracting within the slitting gap 14.

[0035] In this embodiment, the trademark cutting and transfer combination drum can achieve fixed-frequency and fixed-length cutting of trademarks by the blade 20, and can be cut according to the designed length of the trademark. The applicable range of trademark length is increased, that is, the applicable range of container 3 diameter is increased. The functions of the cutting drum and the transfer drum are combined into one combination execution drum, reducing the variety of equipment replacement parts, improving production efficiency, and significantly reducing costs.

[0036] Example 2

[0037] The trademark slitting and transfer assembly drum in this embodiment has the same basic structure as in embodiment 1, but the differences or improvements are as follows: Figure 3 As shown, a vacuum distribution plate 17 is formed between the combined drum body 1 and its base plate 10, creating a vacuum sealing cavity that communicates with the vacuum adsorption hole 11. The vacuum distribution plate 17 is connected to an external vacuum pump or other vacuum source to ensure continuous negative pressure in the vacuum adsorption hole 11. A drive shaft 18 is located in the middle of the combined drum body 1. The drive shaft 18 is fixedly connected to the middle of the combined drum body 1 via a central shaft connector 13 at its top. The central shaft connector 13 is an existing combination of pressure plate, flange, and bolts. A power output shaft is connected to the bottom of the drive shaft 18, enabling the combined drum body 1 and the cutting device 2 to rotate together with the drive shaft 18. A handle 15 can also be detachably fixed on the base plate 10 within the annular body of the combined drum body 1 for easy disassembly of the combined drum body 1. A vacuum plug 19 is sealed and fixed at the top of the vacuum adsorption hole 11.

[0038] like Figure 4 , 5As shown in Figures 6 and 7, the guide seat 21 is fixedly connected to the guide block 25 via the vertical rod 27. The guide block 25 is pressed against the vertical potential energy spring pressure rod assembly 23, which drives the vertical rod 27 to return to its original position within the cavity. The vertical rod 27 guides the lifting and lowering of the guide, thereby improving the pushing accuracy of the cutting tool 20 and thus improving the accuracy of cutting the trademark. The front bottom surface of the guide block 25 is an upward-sloping structure, which is pressed against the push bearing assembly 29. The rear end of the cutting tool 20 is connected to the push bearing assembly 29. The push bearing assembly 29 is pressed against the horizontal potential energy spring pressure rod assembly 26, which drives the cutting tool 20 to return to its original position to the left. The pushing accuracy of the cutting tool 20 can be further improved by pushing the cutting tool 20 through the bearing assembly. Both the vertical potential energy spring pressure rod assembly 23 and the horizontal potential energy spring pressure rod assembly 26 include a guide post, a compression spring surrounding the guide post, and a moving block. The guide post passes through the moving block and is fixedly connected inside the tool holder 22, and is fixed vertically and horizontally respectively. The two moving blocks are pressed vertically and horizontally against the corresponding compression springs respectively, forming potential energy. The push bearing assembly 29 includes two parallel bearings and a pin that connects the two bearings and the rear end of the tool 20 in series. The rear end of the tool 20 is clamped between the two bearings. The inclined surface of the front bottom of the guide block 25 is pressed against the circumferential surface of the two bearings.

[0039] A fixed pulley assembly 24 is vertically fixed to the cavity wall where the fixing part of the cutting tool 20 is located. The fixing part of the cutting tool 20 is tactilely connected to the fixed pulley assembly 24, providing a sliding guide for the translation of the cutting tool 20 to reduce the frictional force of the bearing assembly pushing the cutting tool 20. A movable pulley 251 is rotatably connected to the rear end of the guide block 25. The movable pulley 251 drives the guide block 25 to roll and connect to the cavity wall, providing a sliding guide for the lifting and lowering of the guide block 25 to reduce the frictional force of the vertical rod 27 pushing the guide block 25. A buffer pad 30 is fixed to the cavity wall where the upper end face of the guide block 25 is located to buffer the impact force received by the guide block 25, avoid significant vibration of the cutting tool 20 body, reduce noise, and achieve both the accuracy and smoothness of the movement of the cutting tool 20. A roller 28 is rotatably connected to the top of the vertical rod 27. The vertical rod 27 consists of two symmetrical rollers 28 on either side. The rollers 28 are connected between the two vertical rods 27 by a cylindrical pin. When an external force is applied to the rollers 28, the rollers 28 move downwards, causing the vertical rods 27 to move downwards in a guiding manner. The cutting tool 20 is inverted L-shaped, with a serrated front edge that is sharp and has a high cutting speed. When the diaphragm encounters the cutting tool 20, it is taut due to the forces exerted by the front and rear components (traction position and combined drum 1), easily cutting the required edge. In the instant the combined drum 1 continues to rotate, the diaphragm breaks instantly under the combined force of the front and rear components.

[0040] like Figure 1-7As shown, in this embodiment, the trademark cutting and transfer assembly drum is fixed inside the assembly drum 1. A trademark head transfer block 12 is embedded in the annular body of the assembly drum 1. Small holes with vacuum suction, namely trademark adsorption holes 11, are arranged on its circumferential surface, communicating with the vacuum distribution plate 17. Relying on this vacuum suction force, the trademark is smoothly attached to the trademark head transfer block 12, the trademark tail transfer block 16, and the trademark adsorption holes 11, thus fixing and transferring the trademark. In the middle of the trademark tail transfer block 16, a cutting blade 20 is fixed in a non-cutting position, awaiting the completion of the cutting action, along with a cutting device 2 fixed to the assembly drum 1 body. The annular distance between the trademark head transfer block 12 and the trademark tail transfer block 16 is the trademark application length transferred to the container 3. This length can be achieved by changing the assembly drum body 1 to adjust the annular distance between the trademark head transfer block 12 and the trademark tail transfer block 16, or by adjusting the rotation speed of the assembly drum body 1 and the frequency of the guide block 25's up-and-down sliding. The applicable trademark length is further expanded and achieved through multiple technical means.

[0041] The trademark cutting and transfer combination drum of this embodiment is applied to the labeling machine for large bottled water. Because the diameter of the container 3 of large bottled water is very large and the length of a single trademark is very long, it is impossible to use ordinary cutting drum and transfer drum to set up the labeling station. The trademark cutting and transfer combination drum of this embodiment can complete the cutting and transfer of trademarks, reducing an important component of the conventional labeling station, the cutting drum. It is applicable to cases with large trademark size and large container diameter 3, with low cost and more scientific replacement parts.

[0042] During operation, film-type trademarks are guided by rollers and driven by a traction unit to change their trajectory. Upon reaching the predetermined position on the combined drum body 1, guide block 25 "pushes" the dividing blade 20, completing both transfer and fixed-length cutting on the combined drum. The cut individual trademarks are then carried by the combined drum body 1 to a position tangent to the beverage container 3. Vacuum suction holes 11 on the outer surface of the combined drum body 1 securely fix the individual trademarks to its surface. The control system is designed to arrive synchronously with the beverage container 3. At the moment of contact, the container 3 and the combined drum body 1 are in a purely rolling relationship, and the trademark is picked up by the container 3 and carried away smoothly. Due to the use of this combined drum, the labeling station configuration is greatly compact, and the executable trademark length is significantly increased. The accessories within the labeling station assembly, being existing technology with no significant changes, will not be described in detail here.

[0043] During the operation of the combined drum, a set of trademark head transfer blocks 12 are embedded on the combined drum body 1. The trademark vacuum adsorption holes 11 are arranged on the blocks and communicate with the vacuum distribution plate 17. The trademark is attached flatly to the trademark head transfer block 12, the trademark tail transfer block 16 and the circumference of the annular body of the combined drum 1 by the vacuum adsorption force. The trademark is carried by the combined drum to the position set by the control system. In the middle of the trademark tail transfer block 16, there is a slitting blade 20 that is retracted inside, that is, retracted to a non-slitting position, waiting to be slitting.

[0044] The working process of the slitting device 2: as follows Figure 1-8 As shown, when an external force (such as a cylinder, cam, etc.) acts on the roller 28, the roller 28 moves downward, causing the vertical rod 27 to move downward. Under the joint guidance of the vertical potential energy spring pressure rod assembly 23 and the horizontal potential energy spring pressure rod assembly 26, it moves downward in the guide seat 21, pushing the guide block 25 to move horizontally. When the guide block 25 moves horizontally outward, it drives the blade 20 fixed on it, forming the pushing action of the blade 20, reaching the slitting working state, and completing the cutting of the trademark. There are two sets of fixed pulleys 24, one on the top and one on the bottom, providing guidance for the translation of the blade 20. Figure 8 As shown, the cutting tool 20 extends to the right to reach its working position, completing the slitting process; the cutting tool 20 retracts to the left from its working position. The screw assembly secures the cutting tool holder 22 to the assembly drum 1. The slitting device 2 is purely mechanical, employing precise guiding mechanisms for all directions requiring precise movement. Once properly adjusted, the movement of the cutting tool 20 remains consistently precise, ensuring stable and accurate working precision. The buffer pad 30, made of elastic materials such as rubber or EVA foam, absorbs the impact force on the guide block 25, isolating it from the impact on the cutting tool 20 body. This prevents significant vibration of the cutting tool 20 body and reduces noise. This component design achieves both the precision and smoothness of the cutting tool 20's movement.

[0045] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
