Description

Technical Field

[0001] This utility model relates to the field of trademark cutting technology, and more specifically to a film-type trademark cutting device. Background Technology

[0002] In equipment using film-type labels, the roll film is typically printed with a fixed-length pattern. It usually needs to be cut into individual labels of fixed length at predetermined locations, a process commonly known as a "slitting drum." A typical slitting drum has moving and stationary blades; the stationary blade generally acts as a support blade. When the container diameter is large and the required label length increases, the stationary blade, due to its fixed position, needs adjustment or replacement. This limits the applicable container diameter range, leading to longer production downtime and reduced production efficiency. Utility Model Content

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

[0004] To address the technical problem of limited applicable container diameters when cutting trademarks in existing technologies, this utility model provides a film-type trademark cutting device. By providing only a moving blade and a blade seat cavity that allows the blade to slide up and down and left and right, the blade can cut trademarks at a fixed frequency, thereby increasing the applicable range of trademark length, which in turn increases 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 film-type trademark slitting device includes a blade, a blade holder, a guide seat, and a guide block. The blade holder has an internal cavity, which is generally an L-shaped channel within the blade holder. The guide seat and the blade are slidably connected to the cavity vertically and horizontally, respectively. The bottom of the guide seat is connected to the guide block, and the rear end of the blade is connected to the guide block. The front cutting edge of the blade protrudes from the side of the blade holder. When the guide block slides up and down with the guide seat, it pulls and pushes the blade to slide left and right, achieving a fixed-frequency cutting of the trademark. This increases the applicable range of trademark length, which in turn increases the applicable range of container diameter. It eliminates the need for a stationary blade, reduces the variety of equipment replacement parts, improves production efficiency, and significantly reduces costs.

[0008] In a further thin-film trademark slitting device, the guide seat is fixedly connected to the guide block via a vertical rod; the guide block is pressed against the vertical potential energy spring pressure rod assembly, which drives the vertical rod to reset upward within the cavity. The vertical rod guides the lifting and lowering process to improve the pushing accuracy of the cutting tool, thereby improving the accuracy of trademark cutting.

[0009] A further thin film trademark slitting device has an upward-sloping 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.

[0010] In a further thin film trademark slitting device, a set of fixed pulleys is vertically fixed on the cavity wall where the blade is fixed. The fixed part of the blade is rolledly connected to the set of fixed pulleys, which provides sliding guidance for the translation of the blade, so as to reduce the friction force of the bearing assembly pushing the blade.

[0011] In a further film-type trademark slitting device, a movable pulley is rotatably connected to the rear end of the guide block. 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, thereby reducing the frictional force of the vertical rod pushing the guide block.

[0012] In a further thin film trademark slitting device, a buffer pad is fixed on the cavity wall where the upper end face of the guide block is located to buffer the impact force received by the guide block, avoid significant vibration of the blade body, reduce noise, and achieve both the accuracy and smoothness of blade movement.

[0013] A further film-type trademark slitting device has a roller rotatably 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.

[0014] A further film-type trademark slitting device has an inverted L-shaped blade with a serrated front end. The blade is sharp and has a high feed speed. When the film encounters the blade, it is taut due to the force of the front and rear components (traction position and slitting drum), making it easy to cut the required kerf. In the instant the slitting drum continues to rotate, the film breaks instantly under the combined force of the front and rear components.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] (1) The film trademark cutting device of this utility model can realize the fixed frequency cutting of trademarks by the blade, the applicable range of trademark length is increased, that is, the applicable range of container diameter is increased, no stationary blade is required, the variety of equipment replacement parts is reduced, the production efficiency is improved, and the cost is significantly reduced.

[0018] (2) The film trademark slitting device 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 cutting tool remains stable and continuously accurate.

[0019] (3) The film trademark slitting device 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

[0027] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0028] Example 1

[0029] The film-type trademark cutting device of this embodiment, such as Figure 1 , 2 As shown, it includes a cutting tool 20, a cutting tool holder 22, a guide seat 21, and a guide block 25. The cutting tool holder 22 has a cavity inside, which is generally an L-shaped channel inside the cutting tool holder 22. The guide seat 21 and the cutting tool 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 cutting tool 20 is connected to the guide block 25. The front cutting edge of the cutting tool 20 protrudes from the side of the cutting tool holder 22. When the guide block 25 slides up and down with the guide seat 21, it pulls and pushes the cutting tool 20 to slide left and right.

[0030] In this embodiment, the film-type trademark cutting device can achieve fixed-frequency and fixed-length cutting of trademarks by the blade 20, and can cut according to the designed length of the trademark; the applicable range of trademark length is increased, that is, the applicable range of container diameter is increased, no stationary blade is required, the variety of equipment replacement parts is reduced, production efficiency is improved, and costs are significantly reduced.

[0031] Example 2

[0032] The film-type trademark slitting device in this embodiment has the same basic structure as in Embodiment 1, with the following differences or improvements: Figure 1 , 2 As shown in Figures 3, 4, and 5, 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 transverse 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 is 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.

[0033] 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 blade 20 is inverted L-shaped, with a serrated front edge that is sharp and has a high advancing speed. When the diaphragm encounters the blade 20, it is taut due to the forces exerted by the front and rear components (traction position and slitting drum 1), easily cutting the required kerf. In the subsequent instant the slitting drum 1 continues to rotate, the diaphragm breaks instantaneously under the combined force of the front and rear components.

[0034] like Figure 1-6 As shown, the film-type trademark slitting device of this embodiment is fixed inside the slitting drum 1. A set of trademark head and tail adsorption blocks are embedded in the annular body of the slitting drum 1. Small holes with vacuum suction force, namely trademark adsorption holes, are arranged on its circumferential surface and communicate with the vacuum distribution plate. Relying on this vacuum adsorption force, the trademark is flatly attached to the trademark head transfer block 3, the trademark tail transfer block 3, and the trademark adsorption holes, so that the trademark can be fixed and transferred. In the middle of the trademark tail transfer block 3, a slitting blade 20 is fixed in a non-slitting position, waiting to complete the slitting action, and a slitting device 2 is fixed on the body of the slitting drum 1.

[0035] The entire working process of the slitting device 2 is as follows: Figure 1-6 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 5As 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. A screw assembly secures the cutting tool holder 22 to the slitting drum 1. The slitting device 2 is purely mechanical, employing precise guiding mechanisms for all directions requiring precise movement. Once properly adjusted, the cutting tool 20's movement remains consistently precise, ensuring stable and accurate working accuracy. The buffer pad 30, made of elastic material such as rubber, absorbs the impact force on the guide block 25, isolating it from the impact on the cutting tool 20 body, preventing significant vibration, and reducing noise. This component design achieves both the precision and smoothness of the cutting tool 20's movement.

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.
