[0022] like Figure 1-Figure 6 As shown, the embodiment of the present application provides a fast positioning inkjet coding device for cigarette pack printing, comprising: A workbench 1, wherein the left side and the front and rear sides of the upper end of the workbench 1 are respectively fixedly connected with a first transmission mechanism 2 and a second transmission mechanism 3, the opposite ends of the first transmission mechanism 2 and the second transmission mechanism 3 are both transmission-connected with a transmission block 5, and the transmission blocks 5 of the first transmission mechanism 2 and the second transmission mechanism 3 are both fixedly connected with a transmission connecting plate 6, and the opposite end surfaces of the two transmission connecting plates 6 are evenly fixedly connected with a plurality of positioning shells 18; The internal structures of the first transmission mechanism 2 and the second transmission mechanism 3 are the same. The outer side of the second transmission mechanism 3 is penetrated and inserted with a transmission screw 24 through a connecting bearing 13. The transmission screw 24 is penetrated and inserted with a transmission displacement block 25 through a thread. The transmission displacement block 25 is limited and movably arranged inside the housing of the second transmission mechanism 3. A limiting groove is opened inside the side of the transmission displacement block 25 close to the transmission block 5, and a displacement rod 26 is movably limited and inserted inside the limiting groove. At the same time, a rectangular opening 32 is penetrated and opened on the front and back sides of the side of the transmission displacement block 25 close to the transmission screw 24, and a movably inserted inclined plate 28 is penetrated inside the rectangular opening 32. The inclined plate 28 is fixedly connected to the inner side wall of the housing of the second transmission mechanism 3, and a return spring 31 is also provided on the outer side of the displacement rod 26; The forward and reverse rotation of the transmission screw 24 drives the transmission displacement block 25 to move forward and backward. The transmission displacement block 25 moves forward and backward under the compulsion of the inclined plate 28, so that the displacement rod 26 moves left and right.

[0023] Specifically: the transmission motor 12 is controlled to continuously rotate forward and reverse for a set number of circles, so that each transmission disk 14 can continuously rotate forward and reverse, and drive each transmission screw 24 to continuously rotate forward and reverse, which will cause the transmission displacement block 25 to move forward and backward, and when the transmission displacement block 25 moves forward and backward, under the action of the inclined plate 28, the displacement rod 26 will continuously extend and retract. Such a movement law will cause the two transmission connecting plates 6 to slowly move relative to each other when moving forward, so that the front positioning shell 18 will jam the cigarette pack placed at the rear end of the baffle 9. At this time, as the transmission motor 12 reverses, the transmission connecting plate 6 will move in the opposite direction and backward, and in the process of displacement, it will push the cigarette pack stuck between the positioning shells 18 to move backward, and in this way, the displacement is repeated continuously, and the cigarette pack placed at the rear end of the baffle 9 is continuously transported.

[0024] like Figure 3 As shown: one end of the displacement rod 26 close to the inclined plate 28 is rotatably connected to the roller 27, the other end of the displacement rod 26 is fixedly connected to the transmission block 5, and the outer side of the displacement rod 26 is also movably inserted into the corresponding displacement rectangular opening 4 opened on the opposite side wall of the first transmission mechanism 2 or the second transmission mechanism 3.

[0025] Specifically, the roller 27 can reduce the friction force at the end of the displacement rod 26, so that the extension and retraction of the displacement rod 26 can be smoother.

[0026] like Figure 4 As shown: the outer side of the displacement rod 26 is also symmetrically fixedly connected with a first spring seat 29, and the transmission displacement block 25 is symmetrically fixedly connected with a second spring seat 30 on the inner side of the inserted displacement rod 26, a return spring 31 is provided between the first spring seat 29 and the second spring seat 30, and the front and rear sides of the side walls of the transmission displacement block 25 are symmetrically provided with limiting sliding openings 33, and the first spring seat 29 is movably inserted inside the limiting sliding opening 33.

[0027] Specifically, the return spring 31 is always in a squeezed state, so that the roller 27 can always be displaced in conformity with the end surface of the inclined plate 28 .

[0028] like Figure 2 and Figure 4 As shown: the thread directions of the transmission screws 24 of the first transmission mechanism 2 and the second transmission mechanism 3 are opposite, the rear ends and front ends of the transmission screws 24 of the first transmission mechanism 2 and the second transmission mechanism 3 are respectively sleeved with transmission plates 14, the transmission plates 14 are connected to the active transmission plates 15 through belts 17, and the middle of the active transmission plates 15 are fixedly inserted with transmission rods 16.

[0029] Specifically, the driving rod 16 rotates to drive the active driving disc 15 to rotate, thereby driving the driving disc 14 to rotate through the belt 17, so that the driving screw 24 rotates.

[0030] like Figure 1 As shown: the front and rear sides of the transmission rod 16 are inserted into the front and rear side positioning frames of the workbench 1 through bearings, and the front end of the transmission rod 16 is fixedly connected to the transmission motor 12, and the transmission motor 12 is fixedly connected to the bracket of the workbench 1.

[0031] Specifically, the transmission motor 12 adopts an existing motor on the market, which is a prior art. The transmission motor 12 is equipped with a dedicated control to control the transmission motor 12 to rotate forward and reverse for a set number of circles, and the transmission motor 12 drives the transmission rod 16 to rotate forward and reverse.

[0032] like Figure 3 As shown: an adjustment plate 23 is movably inserted inside the positioning shell 18, an adjustment block 22 is fixedly connected to the middle of the upper end of the adjustment plate 23, an adjustment screw 20 is threadedly inserted into the middle of the upper side of the adjustment block 22, the front and rear ends of the adjustment screw 20 are inserted between the ear blocks 19 through bearings, and an adjustment handle is fixedly connected to the outer end of the adjustment screw 20, a displacement slot is opened in the middle of the upper end of the positioning shell 18, the adjustment block 22 is movably inserted inside the displacement slot, the ear blocks 19 are fixedly connected to both sides of the upper end of the displacement slot of the positioning shell 18, and a stabilizing spring 21 is sleeved on the outside of the adjustment screw 20 between the adjustment block 22 and one of the ear blocks 19.

[0033] Specifically: according to the size of the cigarette pack, the adjusting screw 20 can be adjusted to drive the adjusting block 22 to drive the adjusting plate 23 to move left and right, so that the position of the adjusting plate 23 inside the positioning shell 18 can be adjusted, thereby adjusting the depth of the inner side of the positioning shell 18 to meet the sizes of different cigarette packs, and the stabilizing spring 21 is always in an extruded state.

[0034] like Figure 1 As shown: a connecting support frame 7 is fixedly connected to the outer middle part of the upper end of the workbench 1, a spray terminal 8 is fixedly connected to the middle part of the connecting support frame 7, and the spray terminal 8 is connected to the coding equipment, and the spray terminal 8 is located on the upper center side of the workbench 1.

[0035] Specifically, the spray terminal 8 and the coding equipment are both existing equipment and existing technologies. The spray terminal 8 can code the surface of the cigarette package.

[0036] like Figure 1As shown: a baffle 9 is fixedly connected to the middle of the upper front side of the workbench 1, convex strips 10 are fixedly connected to the left and right sides of the rear end of the baffle 9, an exhaust fan 11 is inserted through the middle of the baffle 9, and the exhaust head of the exhaust fan 11 is located in the middle between the convex strips 10.

[0037] Specifically: the exhaust fan 11 adopts the existing exhaust fan on the market, which is the existing technology. The wind extracted by the exhaust fan 11 needs to be adjusted in size so as not to affect the position of the placed cigarette pack, that is, it will not cause the placed cigarette pack to be deformed. The convex strip 10 can prevent the front end of the placed cigarette pack from being in contact with the front end surface of the baffle 9.

[0038] like Figure 1 As shown: a feeding opening 34 is provided in the middle of the rear end of the workbench 1 .

[0039] Specifically, when the cigarette packs are moved to the rearmost end of the workbench 1 , a conveyor belt may be installed at the unloading port 34 to transfer the coded cigarette packs through the conveyor belt.

[0040] like Figure 1 As shown: the plurality of positioning housings 18 are arranged on the opposite sides of the transmission link plate 6 relative to each other.

[0041] Specifically, the relative displacement of the positioning housing 18 can hold the positioning cigarette pack in place and cause it to move backwards, and the backward displacement is repeated continuously.

[0042] Principle: When the equipment is in use, a manipulator is installed on the front side of the workbench 1, and a clamp is installed on the manipulator. After the clamp grabs the cigarette package and places it at the set position at the rear end of the baffle 9, the exhaust fan 11 is started. The exhaust force of the exhaust fan 11 is pre-adjusted so that the position of the cigarette package will not be blown out of position, and the front end of the placed cigarette package will be close to the rear end of the convex strip 10, so that the cigarette package is placed in a more accurate position. At this time, the transmission motor 12 is started. The transmission motor 12 is connected to a dedicated controller to control the transmission motor 12 to continuously rotate forward and reverse for a set number of circles, so that each transmission disk 14 can continuously rotate forward and reverse, thereby driving each The transmission screw 24 continuously rotates forward and backward, which causes the transmission displacement block 25 to move forward and backward. When the transmission displacement block 25 moves forward and backward, the displacement rod 26 will continuously extend and retract under the action of the inclined plate 28. Such a movement law causes the two transmission connecting plates 6 to slowly move relative to each other when moving forward, so that the frontmost positioning housing 18 will jam the cigarette pack placed at the rear end of the baffle 9. At this time, as the transmission motor 12 reverses, the transmission connecting plate 6 will move in the opposite direction and move backward. During the displacement process, the cigarette pack stuck between the positioning housings 18 will be pushed to move backward. In this way, the displacement is repeated continuously, and the cigarette pack placed at the rear end of the baffle 9 is continuously transported. In the process of transporting cigarette packs, when the transmission connecting plate 6 moves backward and causes the positioning housing 18 to release the cigarette packs, the cigarette packs moved to the lower end of the spraying terminal 8 are sprayed with codes by the spraying terminal 8, and the cigarette packs that move are continuously sprayed with codes. In this way, the running distance of the cigarette packs is the same each time, and the running position is more accurate, so that the coding of the cigarette packs is more accurate and convenient; And according to the size of the cigarette pack, the adjusting screw 20 can be adjusted to drive the adjusting block 22 to drive the adjusting plate 23 to move left and right, so that the position of the adjusting plate 23 inside the positioning shell 18 can be adjusted, thereby adjusting the depth of the inner side of the positioning shell 18 to meet the sizes of different cigarette packs.

[0043] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
