Technical Field

[0001] This utility model relates to the field of tobacco machinery assembly and adjustment technology, specifically to a pressure plate position calibration fixture. Background Technology

[0002] In the M8 cigarette rolling machine, the pressure plate structure is a key component for cigarette forming. Its function is to adjust the paper pressing height and structural fit through an internal mechanism to precisely control the circumference of the cigarette after the cigarette paper wraps the tobacco. Because the M8 equipment has a dual-channel structure, the same pressure plate needs to be adapted to two cigarette channels simultaneously, which makes the structure complex and adjustment difficult.

[0003] Currently, during the debugging process in the industry, maintenance personnel generally use experience-based methods for adjustment, that is, relying on visual inspection, touch, or simple tools to judge the relative positions of various parts. This method has problems such as low accuracy, poor repeatability of work, and high dependence on personnel, which can easily cause fluctuations in the quality of cigarette forming and affect the consistency of finished products. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a pressure plate position calibration fixture, characterized in that it includes: a first calibration arm; and a second calibration arm, which is arranged opposite to and parallel to the first calibration arm. The first calibration arm and the second calibration arm are respectively provided with a plurality of spaced and corresponding calibration parts, and the plurality of calibration parts form two calibration channels extending from the first calibration arm to the second calibration arm for the constrained body to pass through. Mounting components are disposed on the first calibration arm and / or the second calibration arm to enable a detachable connection between the first calibration arm and / or the second calibration arm and the mounting carrier.

[0006] Furthermore, the first calibration arm is provided with a first calibration plane, and the second calibration arm is provided with a second calibration plane; the first calibration plane and the second calibration plane are used to place a level detection device to detect whether the first calibration plane and the second calibration plane are on the same horizontal plane.

[0008] Furthermore, the mounting assembly includes a first mounting structure and a second mounting structure; the first mounting structure includes a first mounting portion disposed on the first calibration arm, a first bolt cooperating with the first mounting portion, and a gasket disposed between the first bolt and the first mounting portion; The second mounting structure includes a second mounting portion disposed on the second calibration arm and a second bolt that mates with the second mounting portion.

[0009] Furthermore, the first mounting part has a first mounting surface; the first mounting surface fits into contact with the surface of the mounting carrier on the side near the first mounting part.

[0010] Furthermore, the lower surface of the second mounting portion is provided with an upwardly recessed portion; the recessed portion forms a second mounting surface, which fits and cooperates with the upper surface and adjacent side surfaces of the mounting carrier.

[0011] Furthermore, the second bolt is a hand-tightening bolt.

Detailed Implementation

[0019] The following provides a detailed description of specific embodiments of the present invention. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0020] In this invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a pressure plate position calibration fixture, including: a first calibration arm 1, a second calibration arm 2, and a mounting assembly. The first calibration arm 1 and the second calibration arm 2 are arranged opposite to each other and parallel to each other. The first calibration arm 1 and the second calibration arm 2 are respectively provided with multiple spaced calibration parts 3 for corresponding calibration parts, forming two calibration channels 4 extending from the first calibration arm 1 to the second calibration arm 2 and allowing the constrained body to pass through. The mounting assembly is disposed on the first calibration arm 1 and / or the second calibration arm 2 to achieve a detachable connection between the first calibration arm 1 and / or the second calibration arm 2 and the mounting carrier. It should be noted that the constrained body is the key component in the pressure plate that needs to be precisely installed; the mounting carrier is a wall panel on a cigarette machine.

[0023] The fixture consists of two parallel calibration arms with multiple corresponding calibration sections 3 positioned relative to each other, forming two calibration channels 4. The constrained object passes through the calibration channels 4, with its side edges abutting against the calibration sections 3, thus accurately positioning the constrained object within the calibration channels 4 and achieving precise positioning of the entire pressure plate. The mounting assembly ensures that the entire fixture can be detachably mounted on the mounting carrier, facilitating rapid deployment and disassembly.

[0024] The above-mentioned design effectively improves the positioning accuracy and installation consistency of the pressure plate, reduces human error and installation deviation, and enhances the overall product quality. Furthermore, the modular structure of this calibration fixture improves assembly flexibility; the space between the two calibration arms facilitates subsequent disassembly and assembly, thus increasing assembly efficiency.

[0025] Specifically, the number of calibration units 4 and their distribution positions on the calibration arm are determined based on the structural parameters and installation requirements of each component in the cigarette machine pressure plate. In this embodiment, as... Figure 1 As shown, each calibration arm has three calibration sections 4, which are spaced apart along the length of the calibration arm. The calibration sections 4 on the first calibration arm 1 and the second calibration arm 2 are positioned in a one-to-one correspondence to achieve precise positioning and synchronous calibration of the constrained body. It should be noted that although the calibration sections 4 differ slightly in shape, their structural function is the same, all used for positioning and calibrating the pressure plate. Therefore, they are all labeled with the same number in the attached drawings.

[0026] like Figure 1 As shown, in one possible implementation, the calibration unit 3 is a boss structure located at the lower part of the calibration arm, and its vertical height is a preset height. This preset height is determined based on the structural dimensions and installation positions of each key component on the pressure plate, ensuring that while providing effective limiting for the constrained body, it does not interfere with the installation space of other components on the pressure plate, thereby guaranteeing the spatial compatibility and accuracy consistency of the overall assembly. Furthermore, the vertical heights of multiple calibration units 3 can be set independently to adapt to the different positioning requirements of multiple components on the pressure plate, forming a differentiated limiting structure, which improves the accuracy and structural adaptability of multi-point limiting.

[0027] Understandably, the calibration section 4 can not only adopt a boss structure, but can also be designed as a guide rail groove, a wedge-shaped limiting block, or an adjustable screw structure. In terms of material selection, the calibration section 4 can be made of steel, hard aluminum, or engineering plastics, depending on the working intensity and frequency of use. To enhance wear resistance, a coating can be added to its surface or hard pads can be embedded.

[0028] In one possible implementation, a first calibration plane 11 is provided on the first calibration arm 1, and a second calibration plane 21 is provided on the second calibration arm 2. The first calibration plane 11 and the second calibration plane 21 are used to place a level detection device to detect whether the first calibration plane 11 and the second calibration plane 21 are on the same horizontal plane.

[0029] In this embodiment, the working principle of the calibration fixture is as follows: the operator installs the first calibration arm 1 and the second calibration arm 2 at two preset positions on the cigarette machine wall panel, forming a reference positioning structure. These preset positions are pre-set by the relative positions of the wall panel and the pressure plate. After installation, the operator places the level detection device across the first calibration plane 11 and the second calibration plane 21 and fine-tunes the position and posture of the calibration arms. When the level detection device displays a level state, the calibration fixture is considered fully installed. The operator achieves precise installation of the pressure plate by positioning the constrained body within the calibration channel 4. It should be noted that the level detection device is a commonly used device in the prior art for detecting whether a plane is level, such as a bubble level, electronic level, or laser level, and is a known device in this technical field. This utility model does not claim protection for the structural innovation of the device itself.

[0030] The above settings ensure that the tooling has a good installation posture during use, effectively avoid calibration errors caused by uneven assembly, improve the accuracy and consistency of pressure plate positioning, and enhance the stability and reliability of overall operation.

[0031] In one possible implementation, the first calibration plane 11 and the second calibration plane 21 are machined surfaces. It should be noted that the machined surfaces are planes formed using precision machining processes, such as CNC milling and precision grinding, and their microscopic geometry is closer to that of an ideal plane.

[0032] With the above settings, when using the level detection device to perform plane consistency detection on the first calibration plane 11 and the second calibration plane 21, the high-precision first calibration plane 11 and the second calibration plane 21 can provide a more stable and reliable detection benchmark, ensuring the horizontal consistency and positional accuracy of the pressure plate installation; it can also effectively avoid equipment debugging difficulties and repeated disassembly and assembly caused by processing errors, and improve assembly efficiency.

[0033] It is understandable that the surfaces of the first calibration plane 11 and the second calibration plane 21 may be further treated with anodizing or nickel plating, and after treatment, the film thickness may be refined or controlled to improve surface stability and wear resistance while ensuring that the flatness error remains within the design range.

[0034] like Figure 1As shown, in one possible implementation, the mounting assembly includes a first mounting structure and a second mounting structure. The first mounting structure includes a first mounting portion 12 disposed on the first calibration arm 1, a first bolt 13 cooperating with the first mounting portion 12, and a washer 14 disposed between the first bolt 13 and the first mounting portion 12. A positioning hole is provided at a preset position on the wall panel, and the first bolt 13 cooperates with the positioning hole to provide reliable fastening force while maintaining detachability. The washer 14 is disposed between the head of the first bolt 13 and the first mounting portion 12 to distribute the fastening force, improve the fit stability, and prevent damage to the surface of the first mounting portion 12 during tightening. The second mounting structure includes a second mounting portion 22 disposed on the second calibration arm 2 and a second bolt 23 cooperating with the second mounting portion 22. This configuration facilitates rapid assembly and disassembly, reuse, and high-precision fixing of the tooling.

[0035] The second bolt 23 is preferably a hand-tightening bolt with a knob-shaped head, allowing for quick tightening and loosening of the second calibration arm 2 via manual rotation. This eliminates the need for additional tools and improves on-site operational efficiency. The hand-tightening bolt can be a commercially available standard part, such as a stainless steel bolt with a knurled plastic knob, offering good grip and corrosion resistance. In practical applications of the calibration fixture, the operator can keep the first calibration arm 1 in a fixed position and adjust the installation position of the second calibration arm 2 using the quick-release characteristics of the hand-tightening bolt, simplifying the operation process and improving assembly efficiency.

[0036] In one possible implementation, the first mounting portion 12 has a first mounting surface 15, which fits into the surface of the mounting carrier near the first mounting portion 12 to achieve stable positioning. Figure 1 The first mounting surface 15 is only shown as a portion of its edge outline; in reality, it is completely flush with the plane of the mounting carrier. The lower surface of the second mounting portion 22 has an upward-facing recess 24, which forms the second mounting surface 25. The second mounting surface 25 fits snugly against the upper surface and adjacent sides of the mounting carrier, thereby achieving multi-directional positioning and clamping. This avoids assembly deviations caused by single-surface contact, significantly improving positioning accuracy and installation repeatability, and effectively reducing manual adjustment errors.

[0037] In one possible implementation, the second calibration arm 2 is provided with a reinforcing part 26. The reinforcing part 26 is a diagonal brace structure integrally formed with the second calibration arm 2, one end of which is connected to a part of the second calibration arm 2 away from the second mounting part 22, and the other end is connected to the second mounting part 22.

[0038] Through the above configuration, the reinforcing part 26 forms an oblique connection between the second calibration arm 2 and the second mounting part 22, constituting a stable triangular structural frame to enhance the bending and torsional resistance of the second calibration arm 2 in the vertical and lateral directions. The oblique bracing structure significantly improves the deformation control capability of the second calibration arm 2 under stress during calibration operations, ensuring the structural stability and positional accuracy of the pressure plate calibration process. The reinforcing part 26 adopts an integrally molded oblique bracing structure, which has higher consistency and rigidity compared to traditional additional support components. The oblique connection of the oblique bracing structure can effectively distribute the multi-directional loads caused by the pressure plate and installation operations under stress, preventing structural warping and skewness of the second calibration arm 2, thereby ensuring the stability of the second calibration plane 21.

[0039] In one possible implementation, the first calibration arm 1 and the second calibration arm 2 are each provided with a limiting part 5. The limiting part 5 is a boss structure located at the lower part of the corresponding calibration arm, and its height in the vertical direction is greater than that of the calibration part 3, serving to provide support and auxiliary positioning for the calibration arm. This embodiment, by providing the limiting part 5 at the lower part of the two calibration arms and making its height higher than that of the calibration part 3, ensures that the limiting part 5 first contacts the base plate of the cigarette machine during the installation of the fixture, forming a stable support surface. It should be noted that the base plate is the installation platform where the pressure plate is installed. Through the above configuration, the limiting part 5 can provide height support for the calibration arm and can also assist in the positioning of the calibration arm, thereby ensuring that the entire fixture is in a stable and accurate installation posture during use.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0041] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0042] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
