Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette packaging machinery, in particular to a single-roll and double-roll drawing wire selection control supply device for cigarette strip boxes. Background Art

[0002] In view of the fact that the single pull line of the transparent paper on the cigarette strip is difficult to tear and easy to break, resulting in the embarrassing situation that the transparent paper on the outer strip of the cigarette strip is difficult to remove on important occasions, the brand R&D personnel, from the perspective of humanized detail design, innovatively used the "double-roll pull line" BOPP film, which can remove the transparent paper of the cigarette strip from both ends. That is, if the pull head on one side fails to tear the transparent paper packaging of the cigarette strip, the pull head on the other side can be used to complete the tearing of the transparent paper packaging of the remaining cigarette strips, so that consumers can avoid the above-mentioned scene when unpacking the box. At present, the YB95 strip box transparent paper packaging machine is the mainstream for transparent paper packaging of cigarette strips in actual production. In order to meet the technical requirements of different cigarette production, there are two forms of BOPP film production modes: single-roll wire drawing and double-roll wire drawing. At present, the wire drawing and laminating device of the YB95 strip box transparent paper packaging machine is mainly single-roll wire drawing and laminating device, which cannot meet the production needs of switching between single-roll wire drawing and double-roll wire drawing modes. How the wire drawing and laminating device of the YB95 strip box transparent paper packaging machine can meet these two packaging forms at the same time has become the need of cigarette industrial enterprises.

[0003] The working principle of the wire feeding and pasting device of the YB95 strip box transparent paper packaging machine is briefly described as follows: the wire reel is fixed on the wire feeding assembly, and the wire reel fixing shaft in the wire feeding assembly completes the fixing and release of the wire reel. The wire is pulled out from the wire feeding assembly and passes through multiple steering wheels to the wire pasting assembly; the wire pasting assembly completes the combination of the wire and the strip transparent paper and then enters the strip transparent paper conveying channel. During the transportation of the strip transparent paper, the wire is driven to move, and then the wire reel starts to rotate, and the wire reel fixing shaft and the wire reel rotate together.

[0004] The existing method of replacing the wire pull reel is to clamp the wire pull reel by the conical surfaces of the two inner and outer reel sleeves. The inner reel sleeve is fixed to the threaded rod shaft by a fastening screw, and the outer reel sleeve is assembled on the threaded rod shaft by a thread, and the outer cylindrical surface of the outer reel sleeve is knurled. When installing the wire pull reel, install the inner reel sleeve, pass the wire pull reel on the threaded rod shaft, and then screw the outer reel sleeve on the threaded rod shaft until the wire pull reel cannot rotate, which proves that the wire pull reel is installed. When the wire pull reel is used up, manually unscrew the outer reel sleeve, remove the used wire pull reel core, and then pass the new wire pull reel on the threaded rod shaft, and then screw on the outer reel sleeve and lock it until the wire pull reel cannot rotate. The replacement process requires removing the outer reel sleeve and then replacing the wire pull reel and installing it again, which is a cumbersome process. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] A single-roll and double-roll drawing wire selection control supply device for cigarette cartons, such as Figure 1-3 As shown, the frame 15 includes a first wire feeding assembly 161, a second wire feeding assembly 162, a dual-channel wire deployment steering wheel assembly, a dual-channel wire bonding assembly and a three-speed self-locking knob switch 18. The first wire feeding assembly 161 triggers a first wire break detection electric control circuit through a first wire break detection rocker 171 to determine whether the wire is broken. The second wire feeding assembly 162 triggers a second wire break detection electric control circuit through a second wire break detection rocker 172 to determine whether the wire is broken. The dual-channel wire deployment steering wheel assembly winds the wires pulled out from the first and second wire feeding assemblies 161 and 162 to the corresponding positions of the dual-channel wire bonding assembly.

[0026] The first disconnection detection electric control circuit and the second disconnection detection electric control circuit are connected in parallel with an external power supply. The first disconnection detection electric control circuit is electrically connected to the first normally closed contact input terminal of the three-speed self-locking knob switch 18; the second disconnection detection electric control circuit is electrically connected to the second normally closed contact input terminal of the three-speed self-locking knob switch 18, and the first and second normally closed contact output terminals are electrically connected to the analog signal input module.

[0027] Preferably, the first and second normally closed contact output terminals of the three-speed self-locking knob switch 18 are connected to a resistor, a unidirectional diode and an analog signal input module in sequence. In this embodiment, the analog signal input module is integrated in the input board.

[0028] The first and second wire feeding assemblies 161, 162 respectively include a wire winding tensioning shaft, a flange shaft 1, a wire conveying guide roller group, a wire tensioning swing rod with a wire conveying guide roller, a wire conveying guide roller and a wire reel release damper.

[0029] The wire pulling coil tensioning shaft includes a flange shaft cylinder 2 and a screw rod 7. The flange shaft cylinder 2 is connected to the flange shaft 1 by bolts. The circumferential surface of the flange shaft cylinder 2 is provided with at least one through hole. A wedge-shaped shaft block 3 is installed on one side of the flange shaft cylinder 2. The wedge-shaped shaft block 3 is installed on one end of the screw rod 7 by thread. One end of the screw rod 7 is installed on the side where the flange shaft cylinder 2 and the flange shaft 1 are connected by a bearing 4. A spring 6 is provided in the middle of the screw rod 7. The spring 6 is connected to a tensioning strip 5. The tensioning strip 5 is installed in the through hole on the circumferential surface of the flange shaft cylinder 2. , one end of the tensioning strip 5 is assembled with the wedge-shaped shaft block 1 3, and the other end is assembled with the wedge-shaped shaft block 2 8. The other side of the flange shaft cylinder 2 is threadedly connected with the threaded cover 10, and the threaded cover 10 is connected with the stop cover 11 through the countersunk screw 12. The other end of the screw rod 7 passes through the wedge-shaped shaft block 2 8, the limiting spacer 9, the threaded cover 10, and the stop cover 11 in sequence, and is finally fixedly installed on the hand wheel 14. A bearing 4 is arranged between the threaded cover 10 and the screw rod 7. The wedge-shaped shaft blocks 1, 2, 3, and 8 are assembled at both ends of the screw rod 7 through the opposite spiral threads. Specifically, in this embodiment, the circumferential surface of the flange shaft cylinder 2 is provided with three through holes, and the three tensioning strips 5 correspond to the three through holes one by one. The tensioning strip 5 and the spring 6 are connected in the manner that two through holes are arranged on the tensioning strip 5 for the spring 6 to pass through, and the two springs 6 respectively pass through the through holes at the same position on all the tensioning strips 5 in sequence and then are connected end to end.

[0030] When the tensioning shaft of the wire pulling coil is used, the hand wheel 14 is turned by hand, and the hand wheel 14 drives the screw rod 7 to rotate. The threads at both ends of the screw rod 7 are left-hand and right-hand respectively, which drive the wedge-shaped shaft block 1 3 and the wedge-shaped shaft block 2 8 to move towards or away from each other respectively. When the screw rod 7 is turned clockwise, the wedge-shaped shaft blocks move towards each other, driving the tensioning strip 5 to move outward, thereby fixing the wire pulling coil; when the screw rod 7 is turned counterclockwise, the wedge-shaped shaft blocks move away from each other, and the tensioning strip 5 contracts under the action of the spring 6, thereby releasing the wire pulling coil.

[0031] When assembling the tensioning shaft of the wire pulling reel, the tensioning strip 5 shrinks under the action of the spring 6 and is smaller than the inner diameter of the flange shaft cylinder 2, so that it can be assembled with the flange shaft cylinder 2. If there is no limiting spacer 9, the tensioning strip 5 can shrink to the state during assembly during the movement of the wedge-shaped shaft blocks away from each other. In this way, the tensioning strip 5 will disengage from the through hole on the circumferential surface of the flange shaft cylinder 2 and begin to rotate within the circumferential surface of the flange shaft cylinder 2, affecting the use of the tensioning shaft of the wire pulling reel. If a limiting spacer 9 is used, the tensioning strip 5 will not shrink too small, resulting in disengagement from the through hole on the circumferential surface of the flange shaft cylinder 2, and will always be stuck in the through hole on the circumferential surface of the flange shaft cylinder 2. The limiting spacer 9 limits the movement of the wedge-shaped shaft block 8, so that the tensioning strip 5 does not disengage from the through hole on the circumferential surface of the flange shaft cylinder 2 when it shrinks.

[0032] This embodiment is applied to the YB95 strip box transparent paper packaging machine. On the basis of the original first disconnection detection electric control circuit, the circuit is improved, that is, a second disconnection detection electric control circuit is added in parallel, and the first and second disconnection detection electric control circuits are controlled by the three-speed self-locking knob switch 18 to realize the selection of three different use modes of left-winding wire pulling, double-winding wire pulling, and right-winding wire pulling. At the same time, the first and second disconnection detection electric control circuits are respectively connected in series with a wire-wound resistor and a unidirectional diode to prevent current backflow and protect the detection elements on the first and second disconnection detection electric control circuits.

[0033] When producing double-roll pull-wire packaging, the three-speed self-locking knob switch 18 is rotated to the middle "double-roll pull-wire" gear, and the first or second wire break detection electric control circuit inputs a low-level signal to the analog signal input module. At this time, the first and second pull-wire supply components 161 and 162 are used at the same time, and the first and second pull-wire break detection swing rods 171 and 172 are both effective. If the pull wire breaks, the first or second pull-wire break detection swing rod 171 or 172 will automatically move, causing the output signal of the first or second wire break detection electric control circuit to become a high level, and the analog signal input module reports the fault "the pull wire is broken" to the system, causing the machine to be unable to start and run; when producing single-roll pull-wire packaging, the three-speed self-locking knob switch 18 is rotated to the middle "double-roll pull-wire" gear, and the first or second wire break detection electric control circuit inputs a low-level signal to the analog signal input module. At this time, the first and second pull-wire supply components 161 and 162 are used at the same time, and the first and second pull-wire break detection swing rods 171 and 172 are both effective. If the pull wire breaks, the first or second pull-wire break detection swing rod 171 or 172 will automatically move, causing the output signal of the first or second wire break detection electric control circuit to become a high level, and the analog signal input module reports the fault "the pull wire is broken" to the system, causing the machine to be unable to start and run. It can be rotated to the left "left winding wire" gear position, at which time the first wire supply component 161 is used, the first wire breakage detection rocker 171 is effective, and the second wire breakage detection rocker 172 is invalid, or the third-speed self-locking knob switch 18 can be rotated to the right "right winding wire" gear position, at which time the second wire supply component 162 is used, the second wire breakage detection rocker 172 is effective, and the first wire breakage detection rocker 171 is invalid. If the third-speed self-locking knob switch 18 is rotated to the left "left winding wire" gear position and the second wire supply component 162 is used, or the third-speed self-locking knob switch 18 is rotated to the right "right winding wire" gear position and the first wire supply component 161 is used, the system reports a fault "wire breakage" and cannot be started.

[0034] The principle is explained as follows: the first and second wire break detection electric control circuits are controlled by the three-speed self-locking knob switch 18 to realize the use of single and double-winding wire pulling. When using a single-winding wire pulling, the electric control circuit corresponding to the wire break detection of the other wire pulling supply component is disconnected, which is equivalent to the corresponding wire break detection swing rod being in a failed state, and does not affect the startup and operation of the equipment. During the operation of the equipment, the output signal of the wire break detection electric control circuit is normally low level. If the wire is broken, the output signal of the wire break detection electric control circuit becomes high level. At this time, the high level signal is input to the analog signal input module, and the system will report a fault. It can be understood that as long as the analog signal input module receives a high level, a fault will be reported. When using a single-winding wire pulling, the wire break detection electric control circuit corresponding to the other wire pulling supply component is in a blocked state (that is, the corresponding wire break detection swing rod is in a failed state), and no electrical signal will be input to the analog signal input module, and the equipment will not be shut down. Therefore, if the selection of the three-speed self-locking knob switch 18 does not match the actual use of the wire pulling supply component, the system will report a fault.

[0035] The above is only a specific implementation of the utility model, which enables those skilled in the art to understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
