Description

Technical Field

[0001] This invention belongs to the field of cigarette manufacturing technology, and in particular relates to a tooling for calibrating the movable tobacco tray of a cigarette receiving wheel. Background Technology

[0002] During the cigarette production process, cigarettes are transferred from the rolling and forming machine to the filter receiving machine using a receiving wheel. If the movable cigarette groove of the receiving wheel is not accurately aligned, the cigarettes may fall during the transfer. Therefore, before installing the receiving wheel, the movable cigarette groove of the receiving wheel needs to be aligned to ensure that the movable cigarette groove and the fixed cigarette groove are on the same circumferential surface.

[0003] Currently, the movable flue of the receiving tobacco wheel is usually calibrated using a dial indicator measuring fixture. A movable flue is set between two adjacent fixed flue. A standard mandrel (simulating a cigarette) is placed on both the fixed and movable flue. The two fixed measuring heads at both ends of the measuring fixture contact the standard mandrels on the two fixed flue, respectively. The movable measuring head at the measuring end of the dial indicator contacts the standard mandrel on the movable flue. The four fixing screws of the movable flue are loosened, and the movable flue is lifted by hand. When the dial indicator shows "0", the fixing screws of the movable flue are tightened, and the calibration of one movable flue is completed. Each time the calibration of a movable flue is completed, the dial indicator measuring fixture needs to be installed and removed. Therefore, it takes more than 3 hours to complete the calibration of all movable flue on the equipment. This calibration method is time-consuming and labor-intensive, which seriously restricts production efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a tooling for calibrating the movable smoke tray of the smoke receiving wheel, so as to improve the working efficiency of calibrating the movable smoke tray of the smoke receiving wheel and reduce the labor intensity of calibrating the movable smoke tray of the smoke receiving wheel.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A fixture for calibrating the movable flue of a receiving wheel includes a worktable, a support vertical plate, a main shaft, an indexing turntable, an elastic positioning device for the indexing turntable, and an adjusting roller device. The support vertical plate is mounted on the worktable. The main shaft passes through the support vertical plate along its thickness direction and is rotatably assembled with it. The indexing turntable is fixedly mounted on one end of the main shaft. Multiple positioning holes are spaced apart circumferentially on the circumferential sidewall of the indexing turntable. The elastic positioning device for the indexing turntable is mounted on the support vertical plate and inserts into one of the positioning holes to lock the rotation of the indexing turntable. The adjusting roller device includes an adjusting roller shaft and an adjusting roller. The adjusting roller shaft is fixedly mounted on the support vertical plate. The adjusting roller is rotatably assembled with the adjusting roller shaft, and a locking nut is threaded to the end of the adjusting roller shaft. The adjusting roller is locked by the clamping force of the locking nut. A semi-circular groove is formed on the sidewall of the adjusting roller, which is paired with the fixed or movable flue of the receiving wheel to form a standard mandrel insertion groove.

[0007] Furthermore, the indexing turntable elastic positioning device includes a slide rod base fixedly connected to the support vertical plate, a slide rod slidably assembled with the slide rod base, a convex ball integrally formed with the tail end of the slide rod, a convex ring integrally formed with the slide rod near the head end, and a spring disposed between the convex ring and the slide rod base. The head end of the slide rod is inserted into one of the positioning holes to realize the rotation locking of the indexing turntable.

[0008] Furthermore, the surface of the slide rod base is provided with a deep opening groove and a shallow opening groove offset from each other. A limiting pin is fixedly connected to the slide rod. When the limiting pin is engaged with the deep opening groove, the head end of the slide rod is inserted into the positioning hole. When the limiting pin is engaged with the shallow opening groove, the head end of the slide rod is disengaged from the positioning hole.

[0009] Furthermore, two sets of indexing turntable elastic positioning devices are symmetrically arranged on both sides of the indexing turntable about the central axis of the indexing turntable.

[0010] Furthermore, the indexing turntable is fixedly connected to the main shaft by multiple indexing turntable fixing bolts arranged circumferentially. Each indexing turntable has a waist-shaped hole corresponding to the position of each indexing turntable fixing bolt, and each indexing turntable fixing bolt passes through the corresponding waist-shaped hole.

[0011] Furthermore, the end of the main shaft away from the indexing turntable is integrally connected to an end cap for fixing the rotating body of the smoke wheel.

[0012] Furthermore, one end of the adjustment roller shaft is integrally connected to an adjustment roller shaft base, and the adjustment roller shaft base is fixedly connected to the support vertical plate by bolts.

[0013] Furthermore, the supporting vertical plate is hinged to the workbench via a hinged structure.

[0014] Furthermore, the hinge structure includes a hinge horizontal plate fixedly connected to the workbench, a hinge vertical plate fixedly connected to the support vertical plate, and a hinge connecting the hinge horizontal plate and the hinge vertical plate.

[0015] Furthermore, the hinge vertical plate extends to a limiting boss. When the hinge vertical plate is flipped counterclockwise to a vertical state, the side wall of the workbench contacts the limiting boss, thus preventing the hinge vertical plate from continuing to flip counterclockwise.

[0016] The beneficial effects of this invention are:

[0017] 1. The movable smoke tray alignment fixture of this application does not require disassembly or assembly after each movable smoke tray is aligned. It is simple to operate, saves time and effort, greatly improves work efficiency and reduces labor intensity.

[0018] 2. The indexing turntable and the rotating body of the receiving wheel rotate completely synchronously, and the indexing turntable is positioned by the elastic positioning device of the indexing turntable, which ensures the calibration accuracy of the movable smoke tray.

[0019] 3. It can not only calibrate the movable smoke tray, but also check the wear of the fixed smoke tray, and determine whether the smoke receiving wheel needs to be replaced based on the wear.

[0020] 4. Furthermore, the support vertical plate can be rotated 90° via a hinge structure, facilitating the fixed installation of the connecting smoke wheel. Attached Figure Description

[0030] like Figures 1 to 5 As shown: This embodiment provides a tooling for calibrating the movable flue of a flue-receiving wheel, including a worktable 1, a support vertical plate 3, a main shaft 5, an indexing turntable 4, an indexing turntable elastic positioning device 6, and an adjustment roller device 8. The support vertical plate is mounted on the worktable. In this embodiment, the support vertical plate is hinged to the worktable via a hinge structure 2. The hinge structure includes a hinge horizontal plate 201 fixedly connected to the worktable, a hinge vertical plate 203 fixedly connected to the support vertical plate, and a hinge 202 connecting the hinge horizontal plate and the hinge vertical plate. The hinge vertical plate extends to a limiting boss 10. When the hinge vertical plate is flipped counterclockwise to a vertical position, the side wall of the worktable contacts the limiting boss, preventing the hinge vertical plate from continuing to flip counterclockwise. Based on this, the support vertical plate can achieve a 90° rotation via the hinge structure, facilitating the fixed installation of the flue-receiving wheel.

[0031] The main shaft passes through the support vertical plate along the thickness direction and is rotatably assembled with the support vertical plate. The indexing turntable is fixedly installed at one end of the main shaft. In this embodiment, the indexing turntable is fixedly connected to the main shaft by multiple indexing turntable fixing bolts 9 arranged circumferentially. Each indexing turntable has a waist-shaped hole 402 at the position corresponding to each indexing turntable fixing bolt, and each indexing turntable fixing bolt passes through the corresponding waist-shaped hole. In this way, by loosening the indexing turntable fixing bolts, the rotation of the indexing turntable relative to the main shaft can be finely adjusted.

[0032] The indexing turntable has multiple positioning holes 401 spaced apart circumferentially on its circumferential sidewall. The indexing turntable elastic positioning device is mounted on the support vertical plate and is inserted into one of the positioning holes to achieve rotational locking of the indexing turntable. In this embodiment, the indexing turntable elastic positioning device includes a slide rod base 601 fixedly connected to the support vertical plate, a slide rod 607 slidably assembled with the slide rod base, a convex ball 604 integrally formed with the tail end of the slide rod, a convex ring integrally formed with the slide rod near the head end, and a spring 608 disposed between the convex ring 606 and the slide rod base. The head end of the slide rod is inserted into one of the positioning holes to achieve rotational locking of the indexing turntable. In specific applications, the spring is sleeved on the outside of the slide rod, and the spring generates elastic force to keep the slide rod inclined to be inserted into the positioning hole. When it is necessary to disengage the slide rod from the positioning hole, the slide rod can be lifted by the convex ball. Preferably, the surface of the slide rod base is provided with a deep opening groove 605 and a shallow opening groove 602 offset from each other. A limiting pin 603 is fixedly connected to the slide rod. When the limiting pin engages with the deep opening groove, the head end of the slide rod is inserted into the positioning hole; when the limiting pin engages with the shallow opening groove, the head end of the slide rod disengages from the positioning hole. In this way, the slide rod can be kept in the state of being inserted into the positioning hole or in the state of being disengaged from the positioning hole, thereby improving the convenience of positioning and adjusting the indexing turntable. In this embodiment, two sets of indexing turntable elastic positioning devices are symmetrically arranged on both sides of the indexing turntable about the central axis of the indexing turntable to improve the stability of the indexing turntable positioning.

[0033] The adjusting roller device includes an adjusting roller shaft 802 and an adjusting roller 803. The adjusting roller shaft is fixedly mounted on the supporting vertical plate. The adjusting roller is rotatably assembled with the adjusting roller shaft, and a locking nut 804 is threadedly connected to the end of the adjusting roller shaft. The adjusting roller is locked in rotation by the clamping force of the locking nut. A semi-circular groove 805 is formed on the side wall of the adjusting roller, and it is paired with the fixed smoke groove 11 or the movable smoke groove 12 of the smoke receiving wheel to form a standard mandrel insertion groove. In this embodiment, an adjusting roller shaft base 801 is integrally connected to one end of the adjusting roller shaft, and the adjusting roller shaft base is fixedly connected to the supporting vertical plate by bolts.

[0034] The end of the main shaft away from the indexing turntable is integrally connected to an end cap 7 for fixing the rotating body that receives the smoke wheel.

[0035] The method of using this invention is as follows:

[0036] Place the support plate in a horizontal position and fix the housing of the smoke receiving wheel to the support plate with screws. Then, rotate the smoke receiving wheel and the support plate 90° so that the axis of the smoke receiving wheel is horizontal with the worktable. Pass the end of the main shaft away from the end cover through the rotating body of the smoke receiving wheel and the support plate in sequence, and fix the end cover to the rotating body of the smoke receiving wheel. Rotate the rotating body of the smoke receiving wheel so that one of the fixed smoke grooves of the smoke receiving wheel aligns with the semi-circular groove of the adjusting roller. Loosen the bolts fixing the base of the adjusting roller shaft. Insert a φ7.9mm mandrel between the fixed smoke groove of the smoke receiving wheel and the semi-circular groove of the adjusting roller (loosening the fixing bolts of the adjusting roller base allows adjustment of the adjusting roller angle). Press down on the adjusting roller by hand and insert and remove the mandrel. When the friction of the mandrel is appropriate, tighten the fixing bolts of the adjusting roller base. This adjusts the position of the adjusting roller with the fixed smoke groove as a reference. Then, fix the bolts on the other side of the support plate using the indexing turntable. The indexing turntable is fixedly connected to the main shaft, ensuring that the indexing turntable, main shaft, and receiving wheel are arranged coaxially. The oblong hole on the indexing turntable can be rotated at a small angle to adjust the position of the indexing turntable, ensuring that the sliding rods on both sides can be accurately inserted into the corresponding positioning holes, and the springs provide the corresponding pressure. Then, the rotating body of the receiving wheel is rotated (each time the rotating body of the receiving wheel is rotated, the sliding rod is disengaged from the corresponding positioning hole) to calibrate the movable tobacco groove of the receiving wheel. Specifically, the movable tobacco groove is paired with the semi-circular groove of the adjustment roller, and then the sliding rod is inserted into the corresponding positioning hole of the indexing turntable to achieve synchronous rotation and locking of the rotating body of the indexing turntable, main shaft, and receiving wheel. Next, the fixing bolts of the movable tobacco groove are loosened, and the specification mandrel is inserted. When the friction is consistent with that of the fixed tobacco groove, the fixing screws of the movable tobacco groove are tightened. This completes the calibration of the movable wheel groove. Repeat the same operation method. When the receiving wheel rotates one revolution, all movable tobacco grooves are calibrated.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
