Description

Technical Field

[0001] This invention belongs to the field of filter rod forming machine processing, and in particular relates to a filter rod forming machine leaf spring precision positioning quick installation device and method. Background Technology

[0002] During high-speed operation, the filter rod forming machine's bell-shaped nozzle is fixed to the connecting rod via a bell-shaped nozzle bracket, reciprocating in motion. The leaf spring is fixedly connected to the connecting rod and suspended by a single arm, allowing the connecting rod mechanism to quickly return when it reaches the end of its forward or backward stroke. When installing the leaf spring, the lower end of the leaf spring should be flush with the upper surface of the fixed base, the upper end with the bottom of the support, and the entire leaf spring should be perpendicular to the machine wall panel.

[0003] Currently, the industry standard for installing leaf springs typically involves multiple measurements and positioning using calipers and rulers. This method is prone to measurement errors and random inaccuracies during the measurement process, leading to improper installation of the leaf springs, which affects their lifespan and the operational stability of the equipment. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art described in the background section, where the industry typically uses calipers and rulers for multiple measurements and positioning before installing leaf springs. This method is prone to measurement errors and random errors during the measurement process, leading to improper installation of the leaf springs, affecting their service life and the operational stability of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filter rod forming machine leaf spring precision positioning quick installation device and method, wherein the filter rod forming machine has a fixed base, a support, a connecting rod, a lower locking block and an upper locking block, the device includes a leaf spring quick installation device, the leaf spring quick installation device is provided with an installation part, an L-shaped groove and an auxiliary rod, the leaf spring quick installation device is detachably connected to the fixed base through the installation part, the L-shaped groove is formed by the inward indentation of the edge of the leaf spring quick installation device, and the groove contour of the L-shaped groove is adapted to the outer contour of the support, the auxiliary rod is provided on the leaf spring quick installation device and extends along the installation direction of the leaf spring, the leaf spring quick installation device has a positioning thickness, the positioning thickness is equal to the preset installation distance between the fixed base and the leaf spring.

[0006] Furthermore, the mounting portion includes a first bolt hole and a second bolt hole, the centers of which are located on the same straight line.

[0007] Furthermore, the first bolt hole and the second bolt hole are located on the same side of the L-shaped groove and are offset from the opening direction of the L-shaped groove. The leaf spring quick-installation device is connected to the fixing seat by bolts passing through the first bolt hole and the second bolt hole.

[0008] Furthermore, the two inner wall surfaces of the L-shaped groove are respectively in contact with the two adjacent side walls of the support.

[0009] Furthermore, the distance between the relative walls of the L-shaped groove is greater than the corresponding external dimensions of the support.

[0010] Furthermore, the overall thickness of the leaf spring quick-installation device is consistent.

[0011] Furthermore, the auxiliary rod has a positioning side that coincides with the side of the leaf spring.

[0012] Furthermore, the auxiliary rod and the leaf spring quick-installation device are either integrally formed or fixedly connected.

[0013] Furthermore, the present invention also provides a method for precise positioning and quick installation of leaf springs in a filter rod forming machine. Using the aforementioned precise positioning and quick installation device for leaf springs in a filter rod forming machine, the quick installation device for leaf springs is moved to the fixed seat so that the L-shaped groove corresponds to the outer contour of the support. The quick installation device for leaf springs is detachably connected to the fixed seat through the installation part. The leaf spring is placed against the quick installation device for leaf springs and the installation direction of the leaf spring corresponds to the auxiliary rod. Then, the leaf spring is locked and fixed by the lower locking block and the upper locking block.

[0014] Furthermore, in the method, the installation distance between the fixing seat and the leaf spring is limited by the positioning thickness of the leaf spring quick-installation device, and the installation direction of the leaf spring is corrected by the auxiliary rod. After the leaf spring is fixed, the leaf spring quick-installation device is removed from the fixing seat.

[0015] Compared with existing technologies, the advantages of this filter rod forming machine's leaf spring precision positioning and quick installation device are:

[0016] 1. This invention utilizes the mounting part and L-shaped groove on the leaf spring quick installation device to enable the leaf spring quick installation device to be detachably fixed on the fixed base. The L-shaped groove adapts to the outer contour of the support to achieve quick positioning, thereby solving the problem of low installation efficiency and large positioning error caused by the need for repeated measurement with calipers and rulers in the existing leaf spring installation process.

[0017] 2. This invention, through the positioning thickness of the leaf spring quick installation device and the cooperation of the auxiliary rod, enables the leaf spring to be positioned against the fixed seat according to the preset installation distance between the leaf spring and the fixed seat. The positioning side of the auxiliary rod corrects the installation direction of the leaf spring, thereby solving the problem that existing leaf springs are prone to misinstallation and tilting, which affects service life and equipment operation stability.

[0018] 3. This invention forms a continuous operation process for fixing the leaf spring quick installation device, positioning the support, aligning and correcting the leaf spring, and locking and disassembling it. This further reduces the repeated measurement and adjustment process in the on-site installation steps and improves the consistency of leaf spring replacement and installation.

[0024] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] like Figures 1-3 As shown, this application proposes a leaf spring precision positioning quick installation device for a filter rod forming machine. The filter rod forming machine has a fixed base 11, a support 4, a connecting rod 5, a lower locking block 6, and an upper locking block 7. It includes a leaf spring quick installation device 3, which is provided with an installation part, an L-shaped groove 12, and an auxiliary rod 13. The leaf spring quick installation device 3 is detachably connected to the fixed base 11 through the installation part. The L-shaped groove 12 is formed by the inward indentation of the edge of the leaf spring quick installation device 3, and the groove contour of the L-shaped groove 12 is adapted to the outer contour of the support 4. The auxiliary rod 13 is provided on the leaf spring quick installation device 3 and extends along the installation direction of the leaf spring 8. The leaf spring quick installation device 3 has a positioning thickness, which is equal to the preset installation distance between the fixed base 11 and the leaf spring 8.

[0026] It should be noted that the leaf spring quick-installation device 3 described in this embodiment serves as a positioning reference for the installation of the leaf spring 8. It can form a detachable connection with the fixing seat 11 through the mounting part before the leaf spring 8 is installed, so that the leaf spring quick-installation device 3 can be temporarily fixed in the corresponding installation position of the filter rod forming machine. The L-shaped groove 12 is formed by the inward indentation of the edge of the leaf spring quick-installation device 3, and its groove contour is adapted to the outer contour of the support 4, so that the leaf spring quick-installation device 3 can form a positioning reference with the help of the shape and position of the support 4; the auxiliary rod 13 extends along the installation direction of the leaf spring 8 and can serve as a reference structure for the installation posture of the leaf spring 8; the positioning thickness of the leaf spring quick-installation device 3 corresponds to the preset installation distance between the fixing seat 11 and the leaf spring 8, so that the leaf spring 8 can maintain the predetermined installation distance before the lower locking block 6 and the upper locking block 7 are locked.

[0027] Specifically, when installing the leaf spring 8, the quick-installation device 3 is first fixed to the fixed base 11 via the mounting part, and the L-shaped groove 12 is aligned with the outer contour of the support 4 to determine the installation position of the quick-installation device 3 relative to the fixed base 11, the support 4, and the connecting rod 5. Then, the leaf spring 8 is placed against the quick-installation device 3, and the installation direction of the leaf spring 8 is aligned with the auxiliary rod 13. Finally, the leaf spring 8 is locked in place by the lower locking block 6 and the upper locking block 7. This transforms the installation process, which previously relied on repeated measurements with calipers and rulers, into a tooling positioning process, reducing measurement and random errors, and enabling the leaf spring 8 to be quickly positioned and installed. This solves the problems of low installation efficiency, incomplete installation, and difficulty in ensuring perpendicularity in the prior art.

[0028] Furthermore, such as Figures 1-3 As shown, the mounting part includes a first bolt hole 1 and a second bolt hole 2, and the centers of the first bolt hole 1 and the second bolt hole 2 are located on the same straight line.

[0029] It should be noted that, in this embodiment, the first bolt hole 1 and the second bolt hole 2 serve as the installation connection points between the leaf spring quick-installation device 3 and the fixed base 11. Both are disposed through the leaf spring quick-installation device 3 and mate with corresponding holes on the fixed base 11. The centers of the first bolt hole 1 and the second bolt hole 2 are located on the same straight line, enabling the leaf spring quick-installation device 3 to form a stable linear positioning reference when installed on the fixed base 11, reducing the possibility of misalignment during installation.

[0030] Specifically, when installing the leaf spring quick installation device 3, the first bolt hole 1 and the second bolt hole 2 are aligned with the corresponding holes on the fixing seat 11, and then the connecting piece is passed through the first bolt hole 1 and the second bolt hole 2 for fixing. Since the centers of the first bolt hole 1 and the second bolt hole 2 are on the same straight line, the leaf spring quick installation device 3 can maintain a relatively stable installation posture after being fixed, which provides a basis for the subsequent positioning of the L-shaped groove 12 and the support 4 and the alignment of the auxiliary rod 13 and the leaf spring 8, thereby solving the problem of unstable positioning reference and easy deviation of installation posture in the existing leaf spring installation process.

[0031] Furthermore, such as Figures 1-3 As shown, the first bolt hole 1 and the second bolt hole 2 are located on the same side of the L-shaped groove 12 and are offset from the opening direction of the L-shaped groove 12. The leaf spring quick installation device 3 and the fixing seat 11 are connected by bolts 9 passing through the first bolt hole 1 and the second bolt hole 2.

[0032] It should be noted that, in this embodiment, the first bolt hole 1 and the second bolt hole 2 are located on the same side of the L-shaped groove 12 and are offset from the opening direction of the L-shaped groove 12. This ensures that after the leaf spring quick-installation device 3 is connected to the fixed seat 11 via the bolt 9, the L-shaped groove 12 can still maintain its opening position corresponding to the support 4. The bolt 9 passes through the first bolt hole 1 and the second bolt hole 2, allowing the leaf spring quick-installation device 3 to be quickly fixed and disassembled relative to the fixed seat 11, facilitating the removal of the leaf spring quick-installation device 3 after the leaf spring 8 is installed.

[0033] Specifically, in use, the leaf spring quick-installation device 3 is moved to the fixed base 11, aligning the first bolt hole 1 and the second bolt hole 2 with the holes on the fixed base 11. Then, the bolt 9 is inserted and tightened, fixing the leaf spring quick-installation device 3 onto the fixed base 11. Since the first bolt hole 1 and the second bolt hole 2 are located on the same side of the L-shaped groove 12, the L-shaped groove 12 can continue to align with the support 4 and form a positioning relationship after the leaf spring quick-installation device 3 is fixed. The detachable connection of the bolt 9 avoids the need for repeated manual manipulation of the positioning fixture during installation, thus solving the problems of low positioning efficiency and unstable fixing during leaf spring 8 installation.

[0034] Furthermore, such as Figures 1-3 As shown, the two inner walls of the L-shaped groove 12 are respectively attached to the two adjacent side walls of the support 4.

[0035] It should be noted that the L-shaped groove 12 described in this embodiment has two mating inner wall surfaces, which correspond to two adjacent side walls of the support 4, respectively, so that the L-shaped groove 12 can form a positioning reference by fitting with the outer contour of the support 4. The L-shaped groove 12 is formed by the inward indentation of the edge of the leaf spring quick-installation device 3, so that the leaf spring quick-installation device 3 can be aligned with the corner of the support 4 by means of the groove when it is close to the support 4, thereby reducing the step of manually measuring and determining the installation position.

[0036] Specifically, when the leaf spring quick-installation device 3 is fixed on the fixed base 11, the two inner walls of the L-shaped groove 12 approach and fit against the two adjacent side walls of the support 4, allowing the leaf spring quick-installation device 3 to be quickly positioned using the outer contour of the support 4. In this positioned state, the positional relationship between the leaf spring quick-installation device 3 and the support 4 is defined, and the subsequent installation of the leaf spring 8 can be based on this positional relationship. By using the fitting and positioning between the L-shaped groove 12 and the support 4, the cumulative error caused by multiple measurements with calipers and rulers can be reduced, thereby solving the problem of the leaf spring 8's installation position being difficult to determine quickly.

[0037] Furthermore, such as Figures 1-3 As shown, the distance between the relative walls of the L-shaped groove 12 is greater than the corresponding external dimensions of the support 4.

[0038] It should be noted that the distance between the relative walls of the L-shaped groove 12 described in this embodiment is greater than the corresponding external dimensions of the support 4, allowing the L-shaped groove 12 to smoothly fit into or move out of the corresponding position of the support 4. This structure ensures that the L-shaped groove 12 and the support 4 form a positioning relationship while avoiding the L-shaped groove 12 and the support 4 from being too tight, which would affect the assembly and disassembly of the leaf spring quick-installation device 3, thus providing operating space for the leaf spring quick-installation device 3 during installation and removal.

[0039] Specifically, when the leaf spring quick-installation device 3 is assembled to the fixed base 11, the L-shaped groove 12 avoids and corresponds to the support 4 through its groove space, allowing the leaf spring quick-installation device 3 to move to the predetermined positioning position. After the leaf spring 8 is installed, the fixing structure connected to the mounting part is loosened, and the leaf spring quick-installation device 3 can be removed from the support 4 by means of the dimensional allowance between the L-shaped groove 12 and the support 4. Through this structure, the positioning fixture can be prevented from getting stuck with the support 4 during disassembly, thereby solving the problem of the leaf spring installation device being inconvenient to remove and affecting maintenance efficiency.

[0040] Furthermore, such as Figures 1-3 As shown, the overall thickness of the leaf spring quick-installation device 3 is consistent.

[0041] It should be noted that the overall thickness of the leaf spring quick-installation device 3 described in this embodiment is uniform, enabling it to form a consistent spacing reference at different positions when it mates with the fixing seat 11 and the leaf spring 8. This uniform overall thickness structure facilitates the leaf spring 8 maintaining a flat and positioned state when it abuts against the leaf spring quick-installation device 3, and also ensures that the leaf spring quick-installation device 3 maintains the same support and limiting effect at different installation positions.

[0042] Specifically, during the installation of the leaf spring 8, the leaf spring quick-installation device 3 is positioned between the fixed base 11 and the leaf spring 8. Its consistent thickness corresponds to the preset installation distance between the fixed base 11 and the leaf spring 8, ensuring that the leaf spring 8 remains in place after being abutted against the quick-installation device 3. The consistent thickness of the leaf spring quick-installation device 3 avoids errors that occur when manually measuring distances at different positions with calipers, thus resolving the problem of improper installation of the leaf spring 8 and its impact on subsequent operational stability.

[0043] Furthermore, such as Figures 1-3 As shown, the auxiliary rod 13 has a positioning side that coincides with the side of the leaf spring 8.

[0044] It should be noted that the auxiliary rod 13 described in this embodiment is disposed on the leaf spring quick-installation device 3 and extends along the installation direction of the leaf spring 8. The auxiliary rod 13 has a positioning side that can coincide with the side of the leaf spring 8. This positioning side can serve as a reference for judging the posture of the leaf spring 8 during installation. When the side of the leaf spring 8 coincides with the positioning side of the auxiliary rod 13, it indicates that the leaf spring 8 is arranged along the predetermined installation direction.

[0045] Specifically, when installing the leaf spring 8, place the leaf spring 8 close to the quick-installation device 3 and observe or adjust the side of the leaf spring 8 to align it with the positioning side of the auxiliary rod 13. Once aligned, lock the leaf spring 8 using the lower locking block 6 and the upper locking block 7 to maintain its vertical installation. Correcting the posture of the leaf spring 8 using the positioning side of the auxiliary rod 13 reduces errors caused by relying solely on manual observation or repeated measurements to determine verticality, thus solving the problem of tilted installation of the leaf spring 8 and its impact on service life.

[0046] Furthermore, such as Figures 1-3 As shown, the auxiliary rod 13 and the leaf spring quick-installation device 3 are either integrally formed or fixedly connected.

[0047] It should be noted that the auxiliary rod 13 and the leaf spring quick-installation device 3 described in this embodiment are integrally formed or fixedly connected, so that the auxiliary rod 13 can be stably set on the leaf spring quick-installation device 3 and maintain a constant relative position with the leaf spring quick-installation device 3 during the installation of the leaf spring 8. The stable connection between the auxiliary rod 13 and the leaf spring quick-installation device 3 can ensure that the positioning side of the auxiliary rod 13 maintains a consistent positioning reference during multiple uses.

[0048] Specifically, when using the leaf spring quick installation device 3 to install the leaf spring 8, the auxiliary rod 13 is fixed together with the leaf spring quick installation device 3 at the corresponding position of the fixed base 11 and serves as a reference for the installation direction of the leaf spring 8. Since the auxiliary rod 13 and the leaf spring quick installation device 3 are integrally formed or fixedly connected, the auxiliary rod 13 will not loosen or shift during the alignment process of the leaf spring 8, thereby ensuring the reliability of the coincidence judgment between the leaf spring 8 and the auxiliary rod 13 and solving the problems of unstable positioning reference and difficulty in ensuring the perpendicularity of the leaf spring in the existing manual installation.

[0049] Furthermore, such as Figures 1-3 As shown, this application also proposes a method for precise positioning and rapid installation of leaf springs in a filter rod forming machine. The method uses the aforementioned leaf spring rapid installation device 3 to complete the installation and positioning of the leaf spring 8.

[0050] It should be noted that the filter rod forming machine leaf spring precision positioning quick installation method described in this embodiment uses the leaf spring quick installation device 3 as a temporary positioning reference during the installation process. The installation part forms a detachable connection with the fixed seat 11, the L-shaped groove 12 forms a corresponding positioning with the outer contour of the support 4, and the auxiliary rod 13 forms a reference relationship with the installation direction of the leaf spring 8, so that the leaf spring 8 can complete the position and posture correction before the lower locking block 6 and the upper locking block 7 are locked. After the leaf spring 8 is fixed, the leaf spring quick installation device 3 can be removed from the fixed seat 11 for reuse in subsequent leaf spring installations.

[0051] Specifically, when installing the leaf spring 8 using this method, first move the leaf spring quick-installation device 3 to the fixed seat 11, aligning the L-shaped groove 12 with the outer contour of the support 4. Then, detachably connect the leaf spring quick-installation device 3 to the fixed seat 11 via the installation part. Next, place the leaf spring 8 against the leaf spring quick-installation device 3, aligning the installation direction of the leaf spring 8 with the auxiliary rod 13. Limit the installation distance between the fixed seat 11 and the leaf spring 8 using the positioning thickness of the leaf spring quick-installation device 3. Then, lock and fix the leaf spring 8 using the lower locking block 6 and the upper locking block 7. Finally, remove the leaf spring quick-installation device 3. This transforms the installation process of the leaf spring 8 from repeated manual measurement to tooling positioning and sequential installation, solving the problems of low installation efficiency, large positioning errors, and incomplete installation of the leaf spring 8 in the prior art.

[0052] In summary, the working principle of the leaf spring precision positioning quick installation device and method for the filter rod forming machine is as follows: During use, the leaf spring quick installation device 3 is first moved to the fixed seat 11 of the filter rod forming machine, aligning the first bolt hole 1 and the second bolt hole 2 with the corresponding holes on the fixed seat 11. The leaf spring quick installation device 3 is then detachably fixed to the fixed seat 11 using bolts 9. At this time, the L-shaped groove 12 is formed by the inward indentation of the edge of the leaf spring quick installation device 3, and its groove contour matches the outer contour of the support 4, allowing the inner wall of the L-shaped groove 12 to fit or correspond with the adjacent side wall of the support 4. This quickly determines the installation position of the leaf spring quick installation device 3 relative to the fixed seat 11 and the support 4. Subsequently, the leaf spring 8 is placed against the leaf spring quick installation device 3, utilizing the positioning thickness of the leaf spring quick installation device 3 to correspond to... The preset installation distance between the fixed base 11 and the leaf spring 8 is determined and corrected by aligning the positioning side of the auxiliary rod 13 with the side of the leaf spring 8, ensuring the leaf spring 8 remains vertically installed. The leaf spring 8 is then locked and fixed. After completion, the leaf spring quick installation device 3 can be removed. Thus, this device transforms the leaf spring installation process, which originally relied on repeated measurements with calipers and rulers, into a tooled installation process involving fixing the mounting part, positioning the L-shaped groove 12, limiting the positioning thickness, and correcting with the auxiliary rod 13. This reduces manual measurement errors and random errors, improves the installation efficiency of the leaf spring 8, and avoids affecting the service life of the leaf spring 8 due to installation tilt, inaccurate installation distance, or improper installation. This solves the problems of low leaf spring installation efficiency, poor positioning accuracy, improper installation, and impact on the stable operation of the filter rod forming machine in the background technology.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
