Description

Technical Field

[0001] This invention relates to an auxiliary component, specifically an improved manual tobacco feeding component for a YB65 packaging machine, belonging to the field of tobacco equipment technology. Background Technology

[0002] Currently, when the outer transparent paper of cigarette cartons is not properly wrapped or the pull tab has defects such as misalignment or folding, the operators will remove the outer packaging materials such as transparent paper and pull tab. However, the label paper of these cigarette cartons was not defective when it was wrapped. If the label paper is also removed and a new small pack of cigarettes is added, it will result in a large waste of label paper. The company has relatively strict standards for the evaluation of raw and auxiliary materials. Therefore, the way to save these label papers is to re-process these semi-finished products through the transparent paper packaging machine to re-wrap qualified transparent paper and pull tab.

[0003] Currently, there are several problems when repackaging these semi-finished products through a transparent paper packaging machine: First, it is difficult to put the cigarettes into the cigarette channel on existing equipment; manual cigarette feeding is slow; and the top and bottom of the cigarettes are easily damaged. Figure 6 and Figure 8 As shown, because the distance between the inner and outer pressure plates installed on the left and right rotating bodies (the function of the left and right rotating bodies is to fold the front short edge of the carton label paper, and the function of the inner and outer pressure plates is to prevent the folded front and rear short edges from springing open during the pushing process) is less than the length of a cigarette pack, the two pressure plates must remain elastic to maintain their pressing function. Therefore, when adding cigarettes manually, this pressure plate will get caught on the top and bottom long edge of the carton label paper, making it difficult for the operator to put the cigarette pack into the channel, and it is also easy to damage the top and bottom long edge of the carton label paper. If the operator does not notice that the pressure plate is caught and presses it in forcefully, it will also cause deformation of the pressure plate, thereby damaging the equipment parts.

[0004] In the aforementioned problem, if we remove the outer dextrorotatory body before adding smoke, then we will not encounter the outer tablet press, as shown in the attached diagram. Figure 6 and Figure 8 As shown, this right-handed spiral has a relative position to the cigarette pack. The spiral has long holes designed to adjust its front and back position. When the operator disassembles it, adds cigarettes, and then reassembles it, its relative position may change. This can lead to quality problems with the packaging of the carton label when the equipment is running normally again with the pack. In this case, the repair personnel need to readjust its relative position, which wastes time, manpower, and a lot of carton label paper.

[0005] Second, as attached Figure 6 and Figure 7As shown, the positioning baffle on the existing equipment is too high. When adding cigarettes manually, it will block the cigarette packs from being placed into the cigarette pack channel. Occasionally, it will also bump into the cigarette packs, causing scratches, dents and other appearance quality defects on the cigarette packs.

[0006] Therefore, the key to solving the above-mentioned technical problems lies in developing an auxiliary component for the manual smoke-adding device of the YB65 packaging machine that is simple to operate, practical and reliable. Summary of the Invention

[0007] In view of the many defects and shortcomings existing in the above-mentioned background technology, the present invention has made improvements and innovations, aiming to provide an auxiliary component of a novel manual cigarette adding device for a YB65 packaging machine that is ingeniously designed and easy to assemble and disassemble. This component makes it easier to add cigarette packs while ensuring the integrity of the cigarette packs, thereby improving work efficiency and ensuring that it does not affect the normal operation of the material-carrying channel of subsequent equipment.

[0008] Another objective of this invention is to make it less likely for operators to come into contact with cigarette packs when putting cigarettes into the packaging machine, thereby increasing the efficiency of putting cigarettes into the packaging machine.

[0009] To solve the above problems and achieve the above-mentioned objectives, the present invention provides an improved manual smoke-adding assembly for a YB65 packaging machine, achieved through the following design structure and technical solution:

[0010] As an improvement to the manually assisted smoke-adding component for the YB65 packaging machine, this invention provides an improved version of the component.

[0012] Rotating mechanism (1), the rotating mechanism (1) includes:

[0013] Fixed folding component (11), one end of which is detachably connected to the positioning groove (4) of the base;

[0017] Cover plate connector (3) is detachably installed on cover plate (5).

[0018] As an improvement of the present invention, the connecting end of the fixed folding member (11) and the base positioning groove (4) is provided with an elongated hole (111).

[0019] As a further improvement of the present invention, the elastic pressure plate (12) is fixedly connected to the other end of the fixed folding member (11).

[0020] As a further improvement of the present invention, the elastic pressure plate (12) is detachably connected to the other end of the fixed folding member (11).

[0021] As a further improvement of the present invention, the fixed folding plate limiting block (13) is formed into a square plate structure, and a limiting connection hole (131) is provided through the middle of the fixed folding plate limiting block (13). A protrusion (132) extends outward from the upper surface of the contact end between the fixed folding plate limiting block (13) and the fixed folding member (11).

[0022] As a further improvement of the present invention, the positioning locking member (2) includes:

[0023] Positioning baffle (21), one end of which is connected to the conveyor table;

[0024] Locking element (22) is rotatably connected to the middle of the other end of the positioning baffle (21).

[0025] As a further improvement of the present invention, the cover plate connector (3) has an overall "Z" shaped structure, and the cover plate connector (3) includes:

[0026] Mounting plate (31), one end of which is detachably connected to cover plate (5);

[0027] The connecting plate (32) is connected between the mounting plate (31) and the locking plate (33);

[0028] The locking plate (33) has a not-connecting end provided with a bayonet (331) that is compatible with the locking member (22);

[0029] Handle (34) is located on one side of the upper part of the locking plate (33).

[0030] As a further improvement of the present invention, the mounting plate (31) is in the shape of a "U" shape.

[0031] The locking plate (33) has a trapezoidal plate-like structure.

[0032] The bayonet (331) has a "U" shaped structure.

[0033] As a further improvement of the present invention, the connecting plate (32) is obliquely fixedly connected between the mounting plate (31) and the locking plate (33).

[0034] As a further improvement of the present invention, the connecting plate (32) is vertically fixedly connected between the mounting plate (31) and the locking plate (33).

[0035] The working principle is as follows: Before using the improved manual smoke-adding component designed for the YB65 packaging machine, the auxiliary components that have already been manufactured need to be installed as a backup.

[0036] The specific installation steps are as follows:

[0037] First, the operator installs the elastic pressure plate (12) on the working end face of the fixed folding part (11);

[0038] Then, the operator installs the fixed folding piece (11) on the positioning groove (4) of the machine base. During installation, the working surface of the fixed folding piece (11) should be flush with the working surface of the rotary folder (8) and flush with the inner working surface of the fixed baffle (7).

[0039] Next, the operator installs and fixes the folding plate limiting block (13);

[0040] Then, the operator holds the handle (34) with their right hand and presses it down on the cover plate connector (3) until it contacts the upper surface of the positioning baffle (21). With their left hand, they hold the locking piece (22) and flip it upward to engage it in the slot (331) on the cover plate connector (3).

[0041] Finally, the operator tightens the locking part (22), and the entire installation work is completed. After the installation is completed, it can be used.

[0042] When using, if manual smoke needs to be added, firstly, the operator loosens the locking part (22), and then the operator rotates the locking part (22) downward to disengage it from the latch (331) on the cover plate connector (3);

[0043] Then, the operator holds the handle (34) and lifts the entire cover (5) so that the cover (5) opens to the maximum angle to facilitate the operator adding a cigarette (6) inside;

[0044] Next, the operator removes the fixed folding component (11) without removing the fixed folding plate limit block (13);

[0045] Finally, the operator followed the instructions in the attached document. Figure 1In the indicated direction, a strip of cigarettes (6) without transparent paper is placed into the cigarette conveying channel and pushed to the right into the first lifter. The first lifter then lifts the cigarettes (6) and transparent paper together to complete the U-shaped packaging of the transparent paper. Then, the horizontal pusher plate continues to push, pushing the cigarettes (6) and transparent paper together into the second lifter. During the pushing process, the long side of the transparent paper is folded and the long side is heat-sealed, as well as the short side and lower long side of the end are folded. During the second lift, the upper long side of the end is folded and the end is heat-sealed. At this point, the entire transparent paper packaging process is completed.

[0046] In the entire implementation process described above, the disassembly and assembly of this invention does not affect the normal operation of the subsequent equipment carrying materials. When disassembling, only the fixed folding part (11) needs to be disassembled, without disassembling the fixed folding plate limiting block (13). When installing, only the connecting end of the disassembled fixed folding part (11) needs to be tightly pressed against the outer fixed folding plate limiting block (13), and then the screws need to be tightened so that the fixed folding part (11) can remain in its original relative position.

[0047] In order to improve the efficiency of adding cigarettes (6) during use, the height of the positioning baffle (5) is lowered so that when adding two or three cigarettes at the same time, they will not interfere with the positioning baffle (5) and damage the cigarettes (6). After adding the cigarettes (6), the fixed folding part (11) is reinstalled in the positioning groove (4) of the machine base and close to the fixed folding plate limit block (13). The bolts are tightened so that the axial position of the fixed folding part (11) will not change. After reinstallation, no position adjustment is required. Finally, the operator presses down the cover plate connector (3), flips the locking part (22) upward, and locks the locking part (22) into the slot (331) of the locking plate (33) and then tightens it. In this way, the equipment is restored to its original state and can run normally with materials.

[0048] The beneficial effects of this invention compared to the prior art are:

[0049] 1. This invention is ingeniously designed, easy to assemble and disassemble, simple to operate, practical and reliable. It makes it easier to add cigarette packs while ensuring the integrity of the cigarette packs, thereby improving work efficiency and reducing labor costs.

[0050] 2. The present invention redesigns the existing right-handed helix and processes it into two parts to form a rotating mechanism. The fixed folding plate limiting block of the rotating mechanism is specifically used for positioning. The fixed folding part of the rotating mechanism is re-processed with an elongated hole so that the relative position of the rotating mechanism can be adjusted.

[0051] 3. In terms of disassembly and assembly, this invention does not affect the normal operation of subsequent equipment carrying materials. When disassembling, only the fixed folding part needs to be disassembled, without disassembling the fixed folding plate limiting block. When installing, simply place the connecting end of the disassembled fixed folding part tightly against the outer fixed folding plate limiting block, and then tighten the screws to keep the fixed folding part in its original relative position.

[0052] 4. The present invention redesigns the height of the positioning baffle of the original equipment, and lowers the height of the positioning baffle, so that the operator is less likely to hit the cigarette pack when putting the cigarette into the packaging machine, thereby increasing the efficiency of putting the cigarette into the packaging machine.

[0053] 5. The present invention redesigns the cover plate connector of the original equipment so that the cover plate connector and the redesigned positioning and locking parts can work together to complete the work, so that the redesigned cover plate locking part still plays the original role.

[0054] 6. The protrusions provided on the fixed folding plate limiting block of the present invention can better limit the fixed folding parts. Attached Figure Description

[0072] To make the technical means, inventive features, objectives, and effects of this invention readily understandable, the technical solution of this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0073] As per the instruction manual Figure 1 To the instruction manual Figure 5 An improved manual smoke-adding assembly for a YB65 packaging machine, shown, includes:

[0074] Rotating mechanism 1, comprising:

[0075] A fixed folding component 11 is provided, one end of which is detachably connected to the positioning groove 4 of the base.

[0076] Elastic pressure plate 12 is connected to the other end of fixed folding member 11;

[0077] Fixed folding plate limiting block 13, fixed folding plate limiting block 13 is detachably connected to the end of the machine base positioning groove 4;

[0078] Positioning and locking component 2 is located on one side of the conveyor table;

[0079] Cover plate connector 3 is detachably installed on cover plate 5.

[0080] In this invention, the rotating body mechanism 1 is detachably mounted on the positioning groove 4 of the base.

[0081] The present invention redesigns the existing right-handed helix and processes it into two parts to form a rotating mechanism 1. The fixed folding plate limiting block 13 of the rotating mechanism 1 is specifically used for positioning. The fixed folding part 11 of the rotating mechanism 1 is re-processed with an elongated hole so that the relative position of the rotating mechanism 1 can be adjusted.

[0082] The protrusion 132 provided on the fixed folding plate limiting block 13 of the present invention can better limit the fixed folding member 11.

[0083] Furthermore, such as Figure 5 As shown, the fixed folding member 11 has an elongated hole 111 through the connection end with the positioning groove 4 of the base.

[0084] Specifically, such as Figure 5 As shown, the elastic pressure plate 12 is fixedly connected to the other end of the fixed folding member 11.

[0085] Furthermore, such as Figure 5 As shown, the elastic pressure plate 12 is detachably connected to the other end of the fixed folding member 11.

[0086] Furthermore, such as Figure 1 and Figure 2 as well as Figure 5 As shown, the fixed folding plate limiting block 13 is formed into a square plate structure, and a limiting connection hole 131 is opened through the middle of the fixed folding plate limiting block 13. A protrusion 132 extends outward from the upper surface of the contact end between the fixed folding plate limiting block 13 and the fixed folding member 11.

[0087] In this invention, the limiting connection hole 131 is an elongated hole, and the protrusion 132 on the fixing folding plate limiting block 13 can better limit the fixing folding member 11.

[0088] In terms of disassembly and assembly, this invention does not affect the normal operation of subsequent equipment carrying materials. When disassembling, only the fixed folding part 11 needs to be disassembled, without disassembling the fixed folding plate limiting block 13. When installing, simply place the connecting end of the disassembled fixed folding part 11 tightly against the outer fixed folding plate limiting block 13, and then tighten the screws to keep the fixed folding part 11 in its original relative position.

[0089] Furthermore, such as Figure 3 As shown, the positioning and locking component 2 includes:

[0090] Positioning baffle 21, one end of which is connected to the conveyor table;

[0091] Locking element 22 is rotatably connected to the middle of the other end of positioning baffle 21.

[0092] In this invention, the height of the positioning baffle 21 is lower than the height of the positioning baffle of the current YB65 packaging machine.

[0093] Meanwhile, the present invention redesigns the height of the positioning baffle 21 of the original equipment, reducing the height of the positioning baffle 21, which makes it less likely for the operator to bump into the cigarette pack when putting cigarettes into the packaging machine, thereby increasing the efficiency of putting cigarettes into the packaging machine.

[0094] Furthermore, such as Figure 4 As shown, the cover plate connector 3 has an overall "Z" shaped structure, and the cover plate connector 3 includes:

[0095] Mounting plate 31, one end of which is detachably connected to cover plate 5;

[0096] Connecting plate 32 is connected between mounting plate 31 and locking plate 33;

[0097] The locking plate 33 has a not-connecting end provided with a bayonet 331 that is adapted to the locking member 22;

[0098] Handle 34 is located on one side of the upper part of the locking plate 33.

[0099] In this invention, the height of the connecting plate 32 between the mounting plate 31 and the locking plate 33 is equal to the height reduction of the positioning baffle 21 compared to the positioning baffle of the existing YB65 packaging machine.

[0100] The present invention redesigns the cover plate connector 3 of the original equipment so that the cover plate connector 3 and the redesigned positioning and locking part 2 can work together to complete the work, so that the locking part of the redesigned cover plate 5 still plays the original role.

[0101] Specifically, such as Figure 4 As shown, the mounting plate 31 has an overall "U" shaped structure;

[0102] The locking plate 33 is generally in the form of a trapezoidal plate structure;

[0103] The bayonet 331 has a "U" shaped structure.

[0104] Specifically, such as Figure 4 As shown, the connecting plate 32 is obliquely and fixedly connected between the mounting plate 31 and the locking plate 33.

[0105] Specifically, such as Figure 4 As shown, the connecting plate 32 is vertically fixed between the mounting plate 31 and the locking plate 33.

[0106] Meanwhile, in this invention, all connections referred to are fixed connections, movable connections, or detachable connections. Fixed connections are welded connections or directly processed into an integral structure; movable connections or detachable connections are hinged connections, internal and external threaded connections, bayonet connections, plug-in sleeves, bolt assembly connections, or screw connections.

[0107] In summary, a more specific embodiment of the present invention is as follows:

[0108] Before using the improved manual smoke-adding component for the YB65 packaging machine with the above-mentioned design structure, the already manufactured auxiliary components need to be installed as a backup.

[0109] The specific installation steps are as follows:

[0110] First, the operator installs the elastic pressure plate 12 on the working end face of the fixed folding part 11;

[0111] Then, the operator installs the fixed folding part 11 on the positioning groove 4 of the machine base. During installation, the working surface of the fixed folding part 11 should be flush with the working surface of the rotary folder 8 and the inner working surface of the fixed baffle 7.

[0112] Next, the operator installed and fixed the folding plate limit block 13;

[0113] Next, the operator holds the handle 34 with their right hand and presses the cover plate connector 3 downwards until it contacts the upper surface of the positioning baffle 21, while holding the locking piece 22 with their left hand and flipping it upwards to engage with the latch 331 on the cover plate connector 3.

[0114] Finally, the operator tightens the locking part 22, which completes the installation work. The device is ready for use after installation.

[0115] When using it, if manual smoke needs to be added, firstly, the operator loosens the locking part 22, and then the operator rotates the locking part 22 downward to disengage it from the latch 331 on the cover plate connector 3;

[0116] Then, the operator holds handle 34 and lifts the entire cover 5, opening the cover 5 to its maximum angle so that the operator can add a pack of cigarettes 6 inside;

[0117] Next, the operator removes the fixing folding piece 11 without removing the fixing folding plate limit block 13;

[0118] Finally, the operator followed the instructions in the attached document. Figure 1As shown, a pack of cigarettes 6 without transparent paper is placed into the cigarette conveying channel and pushed to the right into the first elevator. The first elevator then lifts the pack of cigarettes 6 and the transparent paper together to complete the U-shaped packaging of the transparent paper. Next, the horizontal pusher plate continues to push, pushing the pack of cigarettes 6 and the transparent paper together into the second elevator. During the pushing process, the long side of the transparent paper is folded and heat-sealed, as well as the short side and lower long side of the end are folded. During the second lifting process, the upper long side of the end is folded and the end is heat-sealed. At this point, the entire transparent paper packaging process is completed.

[0119] In the entire implementation process described above, the disassembly and assembly of this invention does not affect the normal operation of the subsequent equipment carrying materials. When disassembling, only the fixed folding part 11 needs to be disassembled, without disassembling the fixed folding plate limiting block 13. When installing, simply place the connecting end of the disassembled fixed folding part 11 tightly against the outer fixed folding plate limiting block 13, and then tighten the screws to keep the fixed folding part 11 in its original relative position.

[0120] During use, in order to improve the efficiency of adding cigarette packs 6, the height of the positioning baffle 5 is lowered so that when adding two or three cigarette packs at the same time, they will not interfere with the positioning baffle 5 and damage the cigarette packs 6. After adding the cigarette packs 6, the fixing folding part 11 is reinstalled in the positioning groove 4 of the machine base and close to the fixing folding plate limit block 13. The bolts are tightened so that the axial position of the fixing folding part 11 will not change. No position adjustment is required after reinstallation. Finally, the operator presses down the cover plate connector 3, flips the locking part 22 upward, and locks the locking part 22 into the slot 331 of the locking plate 33 before tightening. In this way, the equipment is restored to its original state and can run normally with materials.

[0121] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
