Description

Technical Field

[0001] The present invention relates to the field of tobacco equipment, and in particular to a cigarette guiding device, a cutting device, a connecting and assembling machine, and a method for adjusting a gap. Background Art

[0002] The filter cigarette slitting device of the tipping machine consists of a cutting drum, a cigarette guide device, a circular cutter, a grinding wheel, etc. On the cutting drum, double-length filter cigarettes are cut into two filter cigarettes of equal length.

[0003] The existing cigarette guiding device includes a fixed bracket, screws and four guide rails. The fixed bracket is fixed to the equipment wall panel by screws, and the four guide rails are fixed to the fixed bracket by locking the screws with the screws. Specifically, the four guide rails are arranged in parallel, with one guide rail closest to the fixed support and the other guide rails successively farther away from the fixed support. According to the different distances from the fixed support, the four guide rails are respectively recorded as: the first guide rail, the second guide rail, the third guide rail and the fourth guide rail. The first guide rail is pressed onto the fixed support by two first screws. The second guide rail is pressed onto the end of the first screw away from the first guide rail by two second screws. The third guide rail is pressed onto the end of the second screw away from the second guide rail by two third screws. The fourth guide rail is pressed onto the end of the third screw away from the third guide rail by two screws.

[0004] During production, due to differences in cigarette accessories or specifications, the gap between the guide rail and the cutting drum needs to be adjusted to ensure the quality of cigarette cutting. To make adjustments, you first need to remove the screw, the third screw, the second screw, the screw, and then the fourth guide rail, the third guide rail, and the second guide rail. Then, keep the first guide rail connected to the first screw, but slightly loosen the first screw so that the guide rail can move radially in the first screw's direction. Next, place two measuring rods of the required specifications between the guide rail and the cutting drum groove, and move the first guide rail along the radial direction of the first screw until it rests against the measuring rods. Next, tighten the first screw and adjust the second, third, and fourth guide rails in the same manner.

[0071] The following combination Figures 1 to 14 The technical solution provided by the present invention is described in more detail.

[0072] The tipping machine includes a slitting device, which is used to cut double-length filter cigarettes into two equal-length filter cigarettes. Due to differences in cigarette ingredients or specifications, the radial clearance P between the guide rail 4 and the cutting drum 5 (also known as the drum) needs to be adjusted to ensure cigarette cutting quality. Radial clearance P refers to the gap P between the guide rail 4 and the cutting drum 5 in the radial direction of the cutting drum 5.

[0073] The slitting device includes a cigarette guiding device, through which the radial gap P between the guide rail 4 and the cutting drum 5 can be quickly adjusted. A plurality of cutting drum grooves 51 are provided along the circumference of the cutting drum 5.

[0074] See also Figure 1 and Figure 2 An embodiment of the present invention provides a cigarette guiding device for quickly adjusting the distance between each guide rail 4 and the cutting drum 5.

[0075] Specifically, an embodiment of the present invention provides a cigarette guiding device, including a force-applying mechanism 1, a mounting mechanism 2, a connecting member 3, and a plurality of guide rails 4. The force-applying mechanism 1 includes a bracket 11, an elastic member 121, and a push member 122; the push member 122 is slidably mounted on the bracket 11; the elastic member 121 pushes against one end of the push member 122 to change the position of the push member 122 relative to the bracket 11. The mounting mechanism 2 includes a locking mechanism and a mounting member 22. The connecting member 3 detachably connects the force-applying mechanism 1 to the mounting mechanism 2. Each of the plurality of guide rails 4 includes a working arc surface 41; each guide rail 4 can be adjustably mounted on the mounting member 22; one end of the push member 122 away from the elastic member 121 pushes against the guide rail 4. The locking mechanism is constructed to lock each guide rail 4 with the mounting member 22.

[0076] When the radial clearance P needs to be adjusted, the measuring rod 6 is placed in the cutting drum groove 51 and abuts against the working arc surface 41 of the guide rail 4 .

[0077] In the above technical solution, the guide rail 4 is mounted on the mounting member 22, and the mounting is adjustable. When the guide rail 4 is in different mounting positions, the radial distance between the guide rail 4 and the cutting drum 5 will change. After the radial gap P between the guide rail 4 and the cutting drum 5 is determined, the guide rail 4 is locked and fixed to the mounting member 22 by a locking mechanism. When the radial gap P between the guide rail 4 and the cutting drum 5 needs to be adjusted, the locking mechanism is first released, and then the measuring rod 6 is inserted into the radial gap P between the guide rail 4 and the cutting drum 5. Under the action of the force-applying mechanism 1, the force-applying mechanism 1 automatically pushes the guide rail 4 toward the cutting drum 5 to reduce the radial gap P between the guide rail 4 and the cutting drum 5. The measuring rod 6 is then removed, and production can continue.

[0078] If it is necessary to increase the radial gap P between the guide rail 4 and the cutting drum 5, the locking mechanism is first loosened, and then the measuring rod 6 is inserted into the radial gap P between the guide rail 4 and the cutting drum 5. Since the push-up member 122 can further compress the elastic member 121 under the action of the measuring rod 6, it is only necessary to tighten the locking mechanism again to fix the guide rail 4 and the mounting member 22; then remove the measuring rod 6 and continue production.

[0079] As can be seen from the above technical solution, the radial gap P between the guide rail 4 and the cutting drum 5 can be adjusted very conveniently. Each guide rail 4 can be adjusted independently of the others, and adjusting one guide rail 4 does not affect the position of the others. Multiple guide rails 4 can be adjusted simultaneously. Furthermore, the adjustment steps for each guide rail 4 are very simple: the operator only needs to loosen the locking mechanism, insert the measuring rod 6, and then tighten the locking mechanism.

[0080] See also Figures 1 to 3The guide rail 4 is the object of action of the force-applying mechanism 1 and the mounting mechanism 2, and what is adjusted is the radial clearance P between the guide rail 4 and the cutting drum 5. There are multiple guide rails 4, and the mounting machine generally includes four guide rails 4. Each guide rail 4 has the same structure and the same installation method. The following text takes one of the guide rails 4 as an example for a detailed introduction. The guide rail 4 is roughly a long strip, and the working arc surface 41 of the guide rail 4 is an inward concave arc surface, and the inward concave arc surface and the cutting drum 5 are the same arc. There is an oblong hole 42 at each end of the guide rail 4, and the long axis center lines A and B of the oblong hole 42 both point to the center of the cutting drum 5. The relative position of the guide rail 4 and the mounting part 22 can be changed through the oblong hole 42, so that the radial clearance P between the guide rail 4 and the cutting drum 5 can be changed.

[0081] Specifically, the force applying mechanism 1 is used to apply thrust to each guide rail 4 so that each guide rail 4 can move away from the force applying mechanism 1 when it is unlocked, thereby changing the relative position of the guide rail 4 and the force applying mechanism 1. In the actual installation process, the installation direction of the force applying mechanism 1 is such that: the direction of the thrust applied by the force applying mechanism 1 is parallel to the direction of the gap P between the guide rail 4 and the cutting drum 5, that is, the direction of the thrust is Figure 1 The marked S direction. The radial gap P between the guide rail 4 and the cutting drum 5 is located in the radial direction of the cutting drum 5.

[0082] As described above, there are multiple guide rails 4, so all guide rails 4 can be installed and connected together. This can make the structure more compact, not too scattered, and also facilitate installation and layout. In some embodiments, the mounting mechanism 2 includes a locking mechanism and a mounting member 22. The mounting member 22 is rod-shaped. See Figure 4 The mounting members 22 have threaded sections at both ends, and the middle portion of the mounting members 22 is a polished rod. There are two mounting members 22. One mounting member 22 fits within the oblong hole 42 at the first end of each guide rail 4, and another mounting member 22 fits within the oblong hole 42 at the second end of each guide rail 4. The two mounting members 22 connect the guide rails 4 together as a single unit. A locking mechanism is installed at each end of each mounting member 22 to prevent the guide rails 4 from falling off.

[0083] In the actual production process, there is a gap N between each guide rail 4. In order to keep each guide rail 4 at different axial positions of the mounting member 22, see Figure 5a and Figure 5b The mounting mechanism 2 further includes a plurality of spacers 23. Each mounting member 22 is sheathed with a plurality of spacers 23. A guide rail 4 is clamped between two adjacent spacers 23. The spacer 23 is a hollow cylindrical sleeve that serves to position the guide rail 4. The relative positional relationship between the mounting member 22, the spacer 23 and the guide rail 4 is shown in FIG. Figure 8 shown.

[0084] Each mounting member 22 is equipped with a plurality of spacers 23 , a first locking member 211 and a second locking member 212 .

[0085] The locking mechanism includes a first locking member 211 and a second locking member 212. The first locking member 211 is mounted on one axial end of each mounting member 22; the second locking member 212 is mounted on the other axial end of each mounting member 22.

[0086] The first locking member 211 detachably connects one end of the mounting member 22 to the connecting portion 112 of the bracket 11, specifically via the connecting member 3. The connecting member 3 includes two through-holes, one of which passes through the mounting member 22. The first locking member 211 can be a nut, which is threadedly connected to the threaded end of the mounting member 22; the other through-hole is detachably connected to the connecting portion 112 of the bracket 11 of the force-applying mechanism 1, specifically via a bolt or nut.

[0087] The second locking member 212 detachably connects the other end of the mounting member 22 to the cantilever of the bracket 11. The specific implementation of the bracket 11 will be described later.

[0088] The first locking member 211 and the second locking member 212 provide fixed support points at both axial ends of the mounting member 22, making the mounting member 22 very secure and less prone to shaking. This ensures that the guide rails 4 mounted on the mounting member 22 are securely positioned during production. It should be noted that the radial clearance P between the guide rails 4 and the cutting drum 5 is adjusted during non-production conditions.

[0089] The implementation of the force applying mechanism 1 is described below.

[0090] Under production conditions, each guide rail 4 and mounting member 22 are fixedly connected by a locking mechanism, and the guide rail 4 is immovable and fixed. Under this condition, the force-applying mechanism 1 and the guide rail 4 maintain abutting contact. When adjustment is required, the locking mechanism is released, allowing the position of the guide rail 4 relative to the mounting member 22 to be adjusted under the action of the force-applying mechanism 1.

[0091] See also Figures 7 to 9 The force-applying mechanism 1 includes a bracket 11, a plurality of elastic members 121, and a plurality of push members 122. All elastic members 121 and push members 122 are mounted on the same bracket 11. Each elastic member 121 corresponds to each push member 122. Each guide rail 4 is equipped with two elastic members 121 and two push members 122. At each end of each guide rail 4, a push member 122 and an elastic member 121 for applying force to the push member 122 are separately provided.

[0092] See also Figures 7 to 9 , Figure 7The bracket 11 of the force applying mechanism 1 is shown in FIG. Figure 1 Structure in the direction shown. Figure 8 The relative position relationship between the bracket 11 of the force applying mechanism 1 and the mounting mechanism 2 is shown. Figure 9 This is a separate structural diagram of the bracket 11 of the force-applying mechanism 1, and its viewing direction is Figure 8 The views shown are in the same direction.

[0093] The bracket 11 is a mounting base for the abutting member 122 and the elastic member 121 . Specifically, the bracket 11 includes a mounting portion 111 , a first cantilever 113 , a connecting portion 112 and a second cantilever 114 .

[0094] The mounting portion 111 is configured to be fixedly connected to a wall. The mounting portion 111 is formed by fixing multiple plates, which can be welded or screwed. The mounting portion 111 is generally T-shaped to meet the installation requirements of the space.

[0095] The connecting portion 112 can be specifically configured as a long, plate-like structure. One end of the connecting portion 112 is fixedly connected to the mounting portion 111, and the same end is also fixedly connected to the first cantilever 113. The other end of the connecting portion 112 is fixedly connected to the second cantilever 114. This fixed connection can be achieved by bolting, welding, or other methods.

[0096] Both the first cantilever 113 and the second cantilever 114 are used to mount the elastic member 121 and the resisting member 122 of the force-applying mechanism 1. Hereinafter, one elastic member 121 and one resisting member 122 are referred to as a set of resisting mechanisms 12. The number of resisting mechanisms 12 mounted on the first cantilever 113 is the same as the number of guide rails 4, and the number of resisting mechanisms 12 mounted on the first cantilever 113 is also the same as the number of guide rails 4.

[0097] The number of sets of elastic members 121 and abutting members 122 installed on the first cantilever 113 is the same as the number of guide rails 4 , and the number of sets of elastic members 121 and abutting members 122 installed on the second cantilever 114 is also the same as the number of guide rails 4 .

[0098] The first cantilever 113 and the second cantilever 114 both use mounting holes 115 to mount the abutting mechanism 12. In some embodiments, the first cantilever 113 and the second cantilever 114 are each provided with a plurality of mounting holes 115; each mounting hole 115 has a set of abutting mechanism 12 mounted therein.

[0099] The centers of the mounting holes 115 on the first cantilever 113 are on the same straight line, and the centers of the mounting holes 115 on the second cantilever 114 are on another straight line. The mounting holes 115 on the first cantilever 113 and the second cantilever 114 are aligned in pairs, see Figure 8 、 Figure 9 Indicated by the horizontal dotted lines.

[0100] See also Figure 10 and Figure 11 The mounting hole 115 is constructed as a stepped through hole. The stepped through hole includes a first hole section 115a, a second hole section 115b, and a third hole section 115c. The inner diameter of the first hole section 115a is larger than that of the second hole section 115b. The inner diameter of the second hole section 115b is larger than that of the third hole section 115c. The inner wall of the first hole section 115a is internally threaded to facilitate the installation of the sealing component 123, which will be described later.

[0101] See also Figures 11 to 12b The abutment 122 is a stepped shaft, comprising a first shaft section 122b and a second shaft section 122c. The diameter of the first shaft section 122b is larger than the diameter of the second shaft section 122c. The diameter of the first shaft section 122b is larger than the inner diameter of the third hole section of the stepped hole, while the diameter of the second shaft section 122c is slightly smaller than the inner diameter of the third hole section. This prevents the abutment 122 from falling out of the third hole section 115c of the stepped through hole. During adjustment, the second shaft section 122c of the abutment 122 presses against the bottom surface 43 of the guide rail 4, providing positioning for the guide rail 4.

[0102] See also Figures 13a to 13c The abutment mechanism 12 also includes a blocking member 123, which is mounted at one end of the stepped through hole to block the opening. Blocking member 123 includes a first recessed portion 123a, located within the first section 115a of the stepped through hole. A hexagonal recess is machined into the end surface of blocking member 123, located outside the stepped through hole. This allows for tightening and loosening of blocking member 123 using a hexagonal tool.

[0103] The first shaft section 122b of the abutting member 122 includes a second inner recess 122a. The second inner recess 122a is located within the first and second holes 115a, 115b of the stepped through hole. The specific location depends on the abutting member 122 and the extension length of the abutting member 122. The first shaft section 122b of the abutting member 122 is movable within the first and second holes 115a, 115b of the stepped through hole.

[0104] The second shaft section 122 c of the abutting member 122 extends out of the stepped through hole to abut against the guide rail 4 .

[0105] See also Figure 11 The elastic member 121 is clamped in the first inner recess 123a and the second inner recess 122a, and the elastic member 121 is in a compressed state to push against the guide rail 4 to move when the guide rail 4 is not fixed by the locking mechanism.

[0106] Continue to see Figure 11In some embodiments, at least one section of the stepped through hole cooperates with the outer wall of the resisting member 122 to guide the linear movement of the resisting member 122. Specifically, the third section of the hole 115c of the stepped through hole cooperates with the second section of the shaft 122c of the resisting member 122 to guide the extension and retraction movement of the resisting member 122. The extension of the resisting member 122 is achieved under the elastic action of the elastic member 121, and the extension of the resisting member 122 is achieved under the action of inserting a measuring rod 6 larger than the gap into the gap P between the guide rail 4 and the cutting drum 5, that is, an external force inserts the measuring rod 6 into the above-mentioned gap P, and the measuring rod 6 pushes the guide rail 4, and the guide rail 4 pushes the resisting member 122 to retract. During the above-mentioned extension and retraction movements, the guide rail 4 is not locked by the locking mechanism.

[0107] In some embodiments, the direction of the elastic force exerted by the elastic member 121 is perpendicular to the length direction of the first cantilever 113 and the second cantilever 114 .

[0108] The present invention also provides a slitting device, comprising a cutting drum 5 and a cigarette guiding device according to any of the technical solutions of the present invention.

[0112] Step S100: Operate the locking mechanism of the cigarette guide device to loosen the fixed connection between each guide rail 4 and the mounting member 22. As described above, each mounting member 22 is provided with a first locking member 211 and a second locking member 212. For example, in a case where the first locking member 211 is closer to the mounting portion 111 of the bracket 11 and the second locking member 212 is farther away, only the second locking members 212 of both mounting members 22 need to be loosened. For a detailed description of each component and its connection relationship, please refer to the above description and will not be repeated here.

[0113] Step S200: Determine whether the gap P between the guide rail 4 of the cigarette guiding device and the cutting drum 5 needs to be increased or decreased.

[0114] Step S300: insert a measuring rod 6 of a corresponding diameter into the gap P according to the size of the gap P to be adjusted.

[0115] Step S400: If the gap P needs to be reduced, the elastic member 121 of the cigarette guiding device automatically pushes the guide rail 4 to move until the gap P between the guide rail 4 and the cutting drum 5 meets the requirement set by the measuring rod 6.

[0116] In some embodiments, the method for adjusting the gap P using the cigarette guide device further includes the following steps:

[0117] Step S500: If the gap P needs to be increased, directly tighten the second locking piece 212 of the mounting mechanism 2, and insert a measuring rod 6 of corresponding diameter into the gap between the guide rail inlet and outlet. Under the action of the measuring rod 6, the gap P between the guide rail 4 and the cutting drum 5 meets the requirements set by the measuring rod 6.

[0118] The above technical solution requires very few operating steps, can realize the rapid adjustment of the gap P between the cutting drum 5 and the guide rail 4, can adapt to different cigarette specifications or auxiliary material production requirements, and does not require disassembly of the cigarette guide device.
