Description

Technical Field

[0001] This utility model relates to the field of tobacco processing machinery technology, and in particular to an auxiliary tool for adjusting the brake linkage. Background Technology

[0002] In the field of tobacco processing machinery technology, a cigarette machine includes a worktable, a cigarette paper tray, a fixed paper roller shaft, and a brake linkage. The brake linkage includes a first rod, a second rod, a spring, a hook spring nut, a locking nut, and an adjuster. The hook spring nut includes a nut body and a screw. One end of the screw has a hook to hook the spring, and the other end passes through the worktable bracket and is threaded into the nut body to adjust the initial tension of the spring. The first end of the first rod is connected to the spring, and the two ends of the second rod are connected to the first rod and the brake pads of the cigarette paper tray, respectively. The second end of the first rod has a locking nut, which locks the relative position of the first rod and the worktable and fixes the adjuster. Loosening the locking nut releases the adjuster, which can adjust the tightness of the brake pads and the distance between the fixed paper roller shaft and other roller shafts to maintain a good condition between the brake pads and the fixed paper roller shaft. If the brake linkage is not adjusted in time, it will cause the brake pads to rub too tightly or too loosely, resulting in uneven swing of the fixed paper roller shaft and ultimately causing the paper tray to not pull smoothly.

[0003] Currently, adjusting the brake linkage to control the paper disc brake and the swing-fixed paper roller shaft requires two people to operate simultaneously. One person needs to use two adjustable wrenches to tighten the hook spring nut, while the other person needs to use an Allen wrench to loosen and tighten the locking nut and adjust the adjuster. Each adjustment takes 10-20 minutes. After the adjustment is completed, the machine needs to be turned on for fine-tuning to achieve the best braking effect and the optimal swing arm clearance of the swing-fixed paper roller shaft, which greatly affects production efficiency.

[0004] Therefore, there is an urgent need for auxiliary tools to adjust the brake linkage in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for adjusting the brake linkage, which can be completed by one person, reducing manpower input, shortening the time of a single adjustment, eliminating the need for repeated debugging, helping to improve production efficiency, and ensuring the working condition of the brake pads and the fixed paper roller shaft.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An auxiliary tool for adjusting the brake linkage, used to adjust the brake linkage mounted on a workbench. The brake linkage includes a first rod, a spring, a hook spring nut, a locking nut, and an adjuster. One end of the spring is connected to the first end of the first rod, and the other end is connected to the hook spring nut. The second end of the first rod is provided with a locking nut to lock the adjuster. The auxiliary tool for adjusting the brake linkage includes:

[0008] The fixture has a support on the workbench. The hook spring nut includes a nut body and a screw. One end of the screw has a hook that is attached to the spring, and the other end passes through the support and is threaded into the nut body. The nut body can rotate relative to the screw to adjust the extension length of the spring. The fixture has a positioning groove that mates with the nut body. The nut body can be inserted into the positioning groove and fixed.

[0009] The screw loosener includes a working end constructed as a polygonal prism that engages with the inner polygonal hole of the locking nut. Rotation of the polygonal prism loosens the locking nut to unlock the adjuster.

[0010] As an alternative to an auxiliary tool for adjusting the brake linkage, the loosening screw also includes a handheld end whose extension direction is perpendicular to the extension direction of the working end, and the handheld end is configured to provide a point of force application.

[0011] As an optional tool for adjusting the brake linkage, the surface of the handpiece is provided with anti-slip texture.

[0012] As an alternative to an auxiliary tool for adjusting the brake linkage, the positioning groove has two opposing sidewalls, and the outer wall of the nut body can abut against and fit against the two sidewalls.

[0013] As an optional auxiliary tool for adjusting the brake linkage, the sidewall of the positioning groove is provided with an elastic buffer layer.

[0014] As an optional auxiliary tool for adjusting the brake linkage, the retainer also has a handrail on its outer wall, which is configured to provide a point of force application.

[0015] As an alternative to an auxiliary tool for adjusting the brake linkage, the retainer has a through hole along its axial direction, through which the working end of the loosening screw can be stored.

[0016] As an optional auxiliary tool for adjusting the brake linkage, the retainer can be magnetically attached to the worktable; or, the retainer can be snapped onto the worktable.

[0017] As an optional tool for adjusting the brake linkage, the loosening screw is made of metal.

[0018] As an optional auxiliary tool for adjusting the brake linkage, the loosening screw has a wear-resistant coating on its surface.

[0019] Beneficial effects:

[0020] This utility model provides an auxiliary tool for adjusting a brake linkage. The tool includes a loosening screw of a retainer. When using this tool, align the positioning groove of the retainer with the nut body of the hook spring nut and fix it to prevent the nut body from rotating during adjustment. Then, insert the polygonal working end of the loosening screw into the inner polygonal hole of the locking nut. Rotating the working end loosens the locking nut, allowing adjustment of the regulator. This auxiliary tool, through the coordinated use of the retainer and loosening screw, allows one person to adjust the brake linkage, reducing manpower, shortening the time required for each adjustment, eliminating the need for repeated adjustments, improving production efficiency, and ensuring the working condition of the brake pads and the fixed paper roller shaft.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] In the field of tobacco processing machinery technology, such as Figure 1As shown, the cigarette rolling machine includes a worktable 100, a cigarette paper tray 300, a fixed paper roller shaft 500, and a brake linkage 200. The paper tray 300, the fixed paper roller shaft 500, and the brake linkage 200 are all mounted on the worktable 100. The brake linkage 200 includes a first rod 201, a second rod 202, a spring 203, a hook spring nut 204, a locking nut 205, and an adjuster 206. One end of the spring 203 is connected to the first end of the first rod 201, and the other end is connected to the hook spring nut 204. The two ends of the second rod 202 are respectively connected to the first rod 201 and the brake pad 400 of the paper tray 300. The second end of the first rod 201 is provided with a locking nut 205 of the lock adjuster 206. The adjuster 206 is used to adjust the tightness of the brake pad 400 and the distance between the fixed paper roller shaft 500 and other roller shafts. Adjusting the brake linkage 200 can maintain a good relationship between the brake pads 400 and the fixed paper roller shaft 500. If the brake linkage 200 is not adjusted in time, the brake pads 400 will be too tight or too loose, causing the fixed paper roller shaft 500 to swing unevenly, which will eventually cause the paper tray 300 to not pull the paper smoothly.

[0041] Specifically, when the regulator 206 rotates clockwise, it causes the first rod 201 to rotate or shift accordingly. Since the first rod 201 is connected to the second rod 202, and the second rod 202 is connected to the brake pad 400, this causes the second rod 202 to pull the brake pad 400 more tightly against the paper tray 300, increasing the friction between the brake pad 400 and the paper tray 300. The movement of the first rod 201 also causes the oscillating fixed paper roller shaft 500 to move closer to other roller shafts, resulting in a reduction in the distance between the oscillating fixed paper roller shaft 500 and other roller shafts. When the regulator 206 rotates counterclockwise, the first rod 201 will rotate or shift in the opposite direction, causing the pulling force of the second rod 202 on the brake pad 400 to decrease, the pressure between the brake pad 400 and the paper tray 300 to decrease, and the brake pad 400 to loosen. The movement of the first rod 201 also causes the oscillating fixed paper roller shaft 500 to move away from other roller shafts, thereby increasing the distance between the oscillating fixed paper roller shaft 500 and other roller shafts. Currently, there is no unified fixed adjustment standard value for brake pad 400 and fixed paper roller shaft 500. Specific adjustments need to be made based on the actual operating status of the cigarette machine, the degree of wear, the production process requirements, and other differentiated factors, which will not be elaborated here.

[0042] It is worth noting that during the adjustment process, the locking nut 205 should be loosened first to allow the adjuster 206 to rotate freely. After the adjustment is completed, the locking nut 205 should be tightened to lock the relative position of the first rod 201 and the worktable 100, and the adjuster 206 should be fixed in a suitable position to maintain the adjusted state.

[0043] Currently, adjusting the brake linkage 200 requires two people to operate. One person uses two adjustable wrenches to fix the nut body 2041 of the hook spring nut 204, while the other person uses an Allen wrench to loosen and adjust the locking nut 205 in order to rotate the adjuster 206. Each adjustment takes 10-20 minutes, and after adjustment, the machine needs to be started for trial operation and fine-tuning to ensure that the brake pad 400 achieves the best braking effect and the fixed paper roller shaft 500 obtains the ideal swing arm clearance. This operation mode not only requires a large amount of manpower and takes a long time to adjust, but also requires repeated debugging, which seriously restricts the improvement of production efficiency.

[0044] This embodiment discloses an auxiliary tool for adjusting the brake linkage, such as... Figures 1-4 As shown, the auxiliary tool for adjusting the brake linkage 200 is used to adjust the brake linkage 200. The auxiliary tool for adjusting the brake linkage includes a retainer 1 and a screw loosener 2. A bracket 101 is provided on the workbench 100. The hook spring nut 204 includes a nut body 2041 and a screw 2042. A hook 2043 is provided at one end of the screw 2042 to be hooked to the spring 203. The other end passes through the bracket 101 and is threadedly engaged with the nut body 2041. The nut body 2041 can rotate relative to the screw 2042 to adjust the extension length of the spring 203. The retainer 1 is provided with a positioning groove 11 that cooperates with the nut body 2041. The nut body 2041 can be inserted into the positioning groove 11 and fixed. The screw loosener 2 includes a working end 21. The working end 21 is constructed as a polygonal prism that is inserted into the inner polygonal hole of the locking nut 205. Rotation of the polygonal prism can loosen the locking nut 205 to unlock the adjuster 206.

[0045] When using this auxiliary tool for adjusting the brake linkage, align the positioning groove 11 of the retainer 1 with the nut body 2041 of the hook spring nut 204 and fix it to prevent the nut body 2041 from rotating during adjustment; then insert the polygonal working end 21 of the loosening screw 2 into the inner polygonal hole of the locking nut 205, and rotate the working end 21 to loosen the locking nut 205, thereby adjusting the adjuster 206. This auxiliary tool, through the coordinated use of the retainer 1 and the loosening screw 2, allows one person to complete the adjustment of the brake linkage 200, reducing manpower input, shortening the time required for a single adjustment, eliminating the need for repeated adjustments, helping to improve production efficiency, and ensuring the working condition of the brake pad 400 and the swing-fixed paper roller shaft 500.

[0046] like Figure 5 As shown, the screw loosener 2 also includes a handheld end 22, the extension direction of which is perpendicular to the extension direction of the working end 21. The handheld end 22 is used to provide a force application point. The handheld end 22 is set perpendicular to the working end 21, providing a stable force application point when operating the working end 21 to loosen or adjust the locking nut 205. This facilitates precise and labor-saving rotation of the working end 21. With the help of the fixing device 1, one person can efficiently complete the adjustment of the brake linkage 200, reducing manpower input, shortening adjustment time, and helping to improve production efficiency.

[0047] In this embodiment, the working end 21 is a hexagonal prism structure with a length of 65 mm, forming a precise fit with the internal hexagonal locking nut 205 with a nominal thread diameter of 5 mm. This ensures that the working end 21 can be stably inserted into the internal hexagonal hole of the locking nut 205. Torque transmission is achieved through the surface contact between the side of the hexagonal prism and the hole wall, avoiding slippage. Simultaneously, the 65 mm length design balances operational space compatibility and leverage ratio, achieving effortless operation through a reasonable lever arm length. Furthermore, the specific length and number of edges of the working end 21 can be adaptively set according to the specifications of the locking nut 205 and the operational space requirements in the actual application scenario.

[0048] It is worth noting that the extension axis of the working end 21 and the extension axis of the handheld end 22 are arranged at a 90-degree angle, forming a T-shaped structure. The working end 21 is used to insert and cooperate with the inner polygonal hole of the locking nut 205, while the handheld end 22 serves as the force application part, realizing labor-saving operation during the loosening and adjusting of the locking nut 205, ensuring the stability and accuracy of the force application process, and facilitating the operator to complete the adjustment work efficiently.

[0049] In this embodiment, the surface of the handheld end 22 is provided with anti-slip texture. The anti-slip texture increases the friction between the hand and the handheld end 22, making it less likely to slip or slip during operation, and allowing for more stable and precise application of force when loosening and tightening the locking nut 205. Combined with the fixing device 1, it allows one person to efficiently complete the adjustment of the brake linkage 200, reducing manpower, shortening time, and improving production efficiency.

[0050] like Figure 6 As shown, the positioning groove 11 has two opposing sidewalls, and the outer wall of the nut body 2041 can abut and fit against the two sidewalls. The abutment and fit between the two opposing sidewalls of the positioning groove 11 and the outer wall of the nut body 2041 can form a stable limit on the hook spring nut 204, preventing the nut body 2041 from rotating and deviating when adjusting the screw loosener 2, ensuring the adjustment accuracy of the brake linkage 200, and in conjunction with the screw loosener 2, helping a single person to complete the adjustment efficiently, reducing manpower time and improving production efficiency.

[0051] In this embodiment, the positioning groove 11 has two opposing sidewalls with a distance of 10 mm between them. Based on the actual size parameters of the nut body 2041, the design achieves both reliable fixing and easy quick insertion and removal, thus providing stable positioning support for the nut body 2041 during the adjustment of the brake linkage 200. In other embodiments, the distance between the two opposing sidewalls can be adaptively adjusted according to the actual size parameters of the nut body 2041, and is not specifically limited here.

[0052] In this embodiment, an elastic buffer layer is provided on the side wall of the positioning groove 11. When the nut body 2041 of the fixed hook spring nut 204 is fixed, the deformation of the elastic buffer layer can offset the impact force generated by the retainer 1, preventing damage to the outer wall of the nut body 2041 due to rigid contact, and ensuring the stability and accuracy of the adjustment process of the brake linkage 200. At the same time, it reduces the wear between the retainer 1 and the nut, and extends the service life of the retainer 1. Optionally, the elastic buffer layer can be made of rubber, silicone, etc., and is not specifically limited here.

[0053] like Figure 6 As shown, a handle 12 is also provided on the outer wall of the fixture 1, which is used to provide a force application point. The handle 12 provides the operator with a stable force application point, which facilitates precise control of the fixture 1 and makes the positioning groove 11 more firmly lock the nut body 2041 of the hook spring nut 204. With the screw loosener 2, it can help a single person to efficiently complete the adjustment of the brake linkage 200, reduce manpower input, shorten adjustment time, and improve production efficiency.

[0054] In this embodiment, two handrails 12 are symmetrically provided on the outer wall of the fixture 1, which makes it easy for the operator to hold and apply force. The force balance is achieved through the symmetrical structure. When the nut body 2041 is fixed by means of the positioning groove 11, the fixture 1 can be stably operated. With the T-shaped structure of the screw loosener 2, one person can efficiently complete the adjustment of the brake linkage 200, which improves the convenience of operation and adjustment efficiency.

[0055] like Figure 7 As shown, the retainer 1 has a through hole 13 along its axial direction, through which the working end 21 of the screw loosener 2 can be stored. The through hole 13 in the axial direction of the retainer 1 can accommodate the working end 21 of the screw loosener 2, so that the two tools form an integrated structure, which is convenient for storage and carrying and avoids the loss of parts; when in use, there is no need to find the tool separately, saving preparation time, and the tool occupies little space when stored, which helps to improve the convenience and efficiency of adjusting the brake linkage 200.

[0056] In this embodiment, the fixture 1 can be magnetically attached to the worktable 100. The magnetic design of the fixture 1 makes it easy to use and store. It can be attached to a designated position on the worktable 100, saving space, facilitating quick positioning and installation, and improving the adjustment efficiency of the brake linkage 200.

[0057] In other embodiments, the retainer 1 can be snapped onto the workbench 100. The snap-fit ​​structure makes the retainer 1 easy to use and does not occupy extra space when stored, improving operational convenience and production efficiency.

[0058] In this embodiment, the screw loosener 2 is made of metal. The metal screw loosener 2 has high strength and wear resistance, can withstand the large torque when adjusting the locking nut 205, is not easily deformed or damaged, and ensures long-term stable use; the rigidity of the metal material allows for precise force transmission, ensuring the adjustment accuracy of the brake linkage 200, and has low maintenance costs. Optionally, the metal material can be carbon steel, stainless steel, aluminum alloy, etc., and is not specifically limited here.

[0059] In this embodiment, the surface of the screw loosener 2 is coated with a wear-resistant coating. This wear-resistant coating reduces frictional wear between the working end 21 and the groove of the locking nut 205, extending the tool's service life and preventing metal debris from falling and affecting equipment operation. The wear-resistant coating also enhances the surface hardness of the tool, making it less prone to slippage when force is applied, ensuring the adjustment accuracy of the brake linkage 200, and contributing to improved production efficiency. Optionally, the wear-resistant coating can be a carbide coating, nitride coating, etc., and is not specifically limited here.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
