Description

Technical Field

[0001] This utility model relates to the field of trademark label processing technology for packaging, and more specifically to a blade clamping assembly. Background Technology

[0002] In the packaging industry, label processing equipment requires label cutting devices. In traditional label cutting devices, the size of the purchased standard parts limits the structural design of the blade, resulting in a large clamping structure and a small blade itself, which makes installation and maintenance inconvenient. Moreover, the traditional blade shaft is a single piece, and corresponding grooves are machined to install the blade components, which is complex, costly, and inconvenient for installation and maintenance. Utility Model Content

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

[0004] To address the aforementioned technical problems in existing label cutting devices, this utility model provides a blade clamping assembly in which the blade is detachably fixed in a reference groove via an airbag clamp, thereby reducing the size and making the blade easier to disassemble and replace.

[0005] 2. Technical Solution

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

[0007] A cutting tool clamping assembly includes a cutting tool, a bearing seat, and a cutting tool shaft connected within the bearing seat, as well as a clamp fixing seat embedded in the shaft surface of the cutting tool shaft and a reference groove formed outward in the clamp fixing seat; the cutting tool is detachably fixed in the reference groove by an airbag clamp, the airbag clamp applies force to the entire bearing surface of the cutting tool, and the airbag volume can be adjusted by increasing or decreasing pressure, resulting in a smaller volume during installation, increased pressure after installation, and decreased pressure during disassembly, achieving the technical effect of making the cutting tool easier to disassemble and replace.

[0008] Further, a pressure plate is installed between the blade and the airbag clamp to ensure that the air pressure is applied evenly to the entire load-bearing surface of the blade.

[0009] Further, a backing plate is provided between the cutting tool and the reference groove wall in the tool clamping assembly. The backing plate can be added as needed and the required thickness can be added.

[0010] The further blade clamping assembly has an axial main vent hole in the middle of the blade shaft, which is connected to the airbag clamp through the air distribution hole. Compressed air is connected to the main vent hole and vents through the middle of the blade shaft. Pressurization does not affect the rotation of the blade shaft.

[0011] Further, the blade clamping assembly consists of two symmetrically arranged clamping bases, with two corresponding blades to improve cutting efficiency.

[0012] A further cutting tool clamping assembly includes an airbag clamping device comprising a clamping seat embedded in the wall of a reference groove, an airbag groove being formed on the end face of the clamping seat near the cutting tool, an airbag being placed inside the airbag groove, and a clamping plate being slidably connected to the wall of the airbag groove outside the airbag to further improve the stability of the applied pressure.

[0013] 3. Beneficial effects

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] The cutting tool clamping assembly of this utility model, with its airbag clamp and pressure plate working together to form a covering working surface, applies force evenly to the entire load-bearing surface of the cutting tool, keeping the cutting tool in a uniform and stable state of force distribution. This greatly alleviates the shortcomings of existing cutting tool mounting slots that are too cramped. The airbag force application is more precise and gentle, requiring only a small amount of compressed air to maintain a stable clamping state. The reduced size of the cutting tool clamp makes the cutting tool assembly easier to disassemble and replace, achieving a significant improvement in the convenience of installation and maintenance.

Detailed Implementation

[0023] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0024] Example 1

[0025] The tool clamping assembly of this embodiment, such as Figure 1 As shown, it includes a cutting tool 8, a bearing seat 1 and a cutting tool shaft 2 connected to the bearing seat 1, a clamp fixing seat 3 embedded in the shaft surface of the cutting tool shaft 2 and a reference groove 4 opened outward in the clamp fixing seat 3; the cutting tool 8 is detachably fixed in the reference groove 4 by an airbag clamp 6.

[0026] In this embodiment, the blade clamping assembly has an airbag clamp 6 that applies force to the entire bearing surface of the blade 8 after inflation. The volume of the airbag 62 can be adjusted by increasing or decreasing pressure. It is smaller in volume during installation, increases pressure after installation, and decreases pressure during disassembly, thus achieving the technical effect of making the blade 8 easier to disassemble and replace.

[0027] Example 2

[0028] The blade clamping assembly in this embodiment has the same basic structure as in embodiment 1, with the following differences or improvements: Figure 2-6 As shown, a pressure plate 7 is also provided between the cutting tool 8 and the airbag clamp 6, so that the air pressure can be evenly applied to the entire bearing surface of the cutting tool 8. A pad 9 is also provided between the cutting tool 8 and the groove wall of the reference groove 4. The pad 9 can be added as needed for the cutting tool 8 and the pad 9 can be added according to the required thickness. The pressure plate 7, the cutting tool 8 and the pad 9 are pressed together by a fastener 5, which is preferably a fixing screw.

[0029] like Figure 3 As shown, an axial main vent 21 is opened at the middle of the end of the cutting tool shaft 2, and it is connected to the airbag clamp 6 through a distribution vent 22. The arrow in the figure indicates the direction of pressurized airflow. The main vent 21 is connected to an external compressed air source, such as an air compressor or high-pressure tank. Air is vented through the middle of the cutting tool shaft 2, so pressurization does not affect the rotation of the cutting tool shaft 2, and avoids instability of the cutting tool 8 caused by changes in the clamping force due to a sudden drop in pressure. Two sets of clamping bases 3 are symmetrically arranged, and correspondingly, two sets of cutting tools 8 are also arranged, forming a symmetrical double-wing structure. This reduces the machining workload of the clamping bases 3 while improving the balance of the cutting tool shaft 2 during high-speed operation. Figure 6 As shown, the airbag clamp 6 includes a clamp seat 60 embedded in the wall of the reference groove 4. An airbag groove 61 is formed on the end face of the clamp seat 60 near the cutting tool 8. A miniature airbag 62 is built into the airbag groove 61. A clamping plate 63 is slidably connected to the wall of the airbag groove 61 outside the airbag 62 to further improve the stability of the applied pressure. The pressure plate 7 has a T-shaped cross-section, facilitating the formation of an embedded structure with the clamp seat 60 and the cutting tool 8 to improve the stability of the connection. Sealing grooves are formed at each connection gap between the air distribution hole 22 and the airbag 62. Sealing rings 64 are fixedly sealed in the sealing grooves to prevent air leakage during processing and ensure the reliability of the air path. An air outlet is formed radially on the cutting tool shaft 2 and sealed by a plug 23.

[0030] In this embodiment, the blade 8 clamping assembly uses a small amount of compressed air from the airbag 62 through the pressure plate 7 and the blade 8 pad 9 to form a covering surface, uniformly applying force to the entire load-bearing surface of the blade 8, maintaining a uniform and stable force on the blade 8. This structure greatly alleviates the space constraints caused by the large size of the standard airbag 62 in the past, and the parts are easy to disassemble and replace; the pressurization of the miniature airbag 62 is more precise and gentle, achieving a significant improvement in the convenience of installation and maintenance.

[0031] 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.
