Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette case manufacturing conveying equipment, and particularly relates to a cigarette case conveying channel. BACKGROUND

[0002] A cigarette case drying channel is disclosed in Chinese Patent Publication No. CN118892975A, which comprises two parallel upper and lower pressing plates, the pressing surfaces of the pressing plates are provided with rectangular mounting grooves, and heating devices are arranged in the mounting grooves. The cigarette case moves between the two pressing plate supports, so that the upper end of the cigarette case is moved through the heating device of the upper pressing plate, and the lower end is moved through the heating device of the lower pressing plate, so that the tab adhesive is dried and solidified, preventing the cigarette case from deforming and expanding before the tab adhesive is dried and solidified, and causing quality defects such as the tab of the cigarette case still expanding after being glued.

[0003] However, the above-mentioned device still has the following defects:

[0004] 1. The movement of the cigarette case between the two pressing plates can only be achieved by the pushing of the subsequent entering cigarette case, that is, only when a cigarette case enters the pressing plates, the cigarette case that has entered between the pressing plates can be moved by the pushing of the subsequently entering cigarette case. When no cigarette case enters, the cigarette case cannot move, and the conveying efficiency of the cigarette case in the drying channel is low, so that the drying channel can only be used for drying the tab adhesive at the tab of the cigarette case, and cannot be used for conveying the cigarette case to the next process equipment at the same time.

[0005] 2. In actual production, in order to ensure the production efficiency of the cigarette case conveying, the operation of transferring the cigarette case from the gluing equipment into the drying channel is usually implemented by a conveying belt device or a cigarette pushing assembly, that is, the conveying belt device directly transports the cigarette case one by one into the drying channel, or the cigarette pushing assembly directly pushes the cigarette case one by one into the drying channel. However, in the process of transporting or pushing the cigarette case into the drying channel by the conveying belt device or the cigarette pushing assembly, since the tab adhesive on the cigarette case has not been dried and solidified in this process, and the tab of the cigarette case is not limited in this process, the cigarette case is more likely to expand the tab before entering the drying channel, and the cigarette case with the expanded tab is blocked at the entrance of the drying channel due to the mismatching shape, so that the risk of the cigarette case being blocked at the entrance of the drying channel is greatly increased.

[0006] 3. When the running speed of the conveying belt device or the cigarette pushing assembly exceeds the drying speed of the drying channel, the accumulation of one or two cigarette cases at the entrance position of the drying channel will cause the risk of the cigarette case conveying being blocked, resulting in the problem that the drying channel cannot flexibly and effectively cope with the problem of the cigarette case being blocked at the entrance of the drying channel.

[0007] 4. When the newly glued cigarette boxes are pushed into the drying channel, they may be squeezed and deformed under the combined action of the abutting friction resistance of the upper and lower pressure plates and the thrust of the cigarette pushing component. When the cigarette pushing component leaves, the cigarette boxes with a large degree of deformation are directly scrapped, and the cigarette boxes with a small degree of deformation may be restored to their original shape. When these cigarette boxes are restored to their original shape, the increased width of the restored deformed cigarette boxes will act in the opposite direction of the cigarette boxes entering the drying channel and in turn act on the next cigarette box that has just arrived at the entrance of the drying channel, causing the next cigarette box that has just arrived at the entrance of the drying channel to be pushed back or even fall from the entrance of the drying channel, affecting the normal transportation of the cigarette boxes. Summary of the Invention

[0008] The present invention provides a cigarette box conveying channel, in which an introduction mechanism is arranged at the front end of the conveying channel to form an introduction channel connecting the conveying channel and the cigarette box outlet of the gluing equipment, thereby effectively preventing the cigarette box overlap from opening before the glue dries and solidifies, and guiding the cigarette box into the conveying channel through the introduction mechanism to reduce the risk of blockage of the cigarette box when it is conveyed in a limited position, so as to solve at least one of the above-mentioned technical problems.

[0009] The technical solution of the present invention to solve the above-mentioned problem is: to provide a cigarette box conveying device, which includes a first conveyor belt, a second conveyor belt, and an introduction mechanism, a conveying channel for transporting cigarette boxes is provided between the first conveyor belt and the second conveyor belt, and the introduction mechanism is connected and arranged between the entrance of the conveying channel and the cigarette box outlet of the gluing device; the introduction mechanism includes two limit assemblies arranged opposite to each other up and down, and an introduction channel is provided between the two limit assemblies, and the introduction channel is used to guide the cigarette boxes from the gluing device into the conveying channel, and the limit assembly is also used to contact the adhesive box paper at the end face overlap of the limit cigarette box.

[0010] Furthermore, the limiting assembly includes a limiting main board, which is arranged at the lower edge or upper edge of the conveying channel, and the distance from the end of the limiting main board to the entrance end of the conveying channel is less than the width of a cigarette box. The inlet channel is the area between two limiting main boards arranged opposite to each other up and down, and the limiting assembly limits the adhesive box paper by making the limiting main board abut against the end overlap of the cigarette box.

[0011] Furthermore, the limiting assembly also includes limiting side plates and a mounting base. Relative to the conveying direction of the cigarette box, the limiting side plates are provided on both sides of the limiting main board, and the limiting side plates are used to prevent the cigarette box from falling out of the introduction channel to both sides; the limiting side plates and the limiting main board are both fixedly mounted on the mounting base.

[0012] Further, the guide mechanism further comprises a mounting base, the limiting assembly is vertically movably arranged on the mounting base, and the limiting assembly is adjusted in size of the guide channel by moving relative to the mounting base, so as to adapt to the cigarette case of different height sizes.

[0013] Further, the limiting assembly and the mounting base are provided with an elastic expansion member, the limiting assembly is elastically self-adaptively lifted and moved relative to the mounting base through the elastic expansion member, so as to automatically adapt to the cigarette case of different height sizes.

[0014] Further, the guide mechanism further comprises a height limiting adjustment assembly for limiting the height position of the limiting assembly; the height limiting adjustment assembly comprises a sliding groove vertically arranged on the mounting base, a sliding rail arranged at the bottom of the limiting main plate, and an abutting limiting adjustment assembly, the sliding rail is vertically slidably arranged in the sliding groove, and the abutting limiting adjustment assembly limits the sliding stroke of the sliding rail to limit the highest movable position of the limiting assembly arranged above or the lowest movable position of the limiting assembly arranged below.

[0015] Further, the abutting limiting adjustment assembly comprises a first adjustment insertion hole arranged on the mounting base, a second adjustment insertion hole arranged on the sliding rail, an adjustment insertion rod inserted into the first adjustment insertion hole and the second adjustment insertion hole, and a limiting insertion pin inserted into the sliding rail, the adjustment insertion rod is further provided with a circular truncated cone section gradually increasing or decreasing in diameter along the axial direction, and the adjustment insertion rod is axially moved to make the positions with different diameters on the circular truncated cone section abut against the limiting insertion pin to limit the highest slidable position of the sliding rail of the limiting assembly arranged above or the lowest slidable position of the sliding rail of the limiting assembly arranged below.

[0016] Further, the two ends of the adjustment insertion rod are provided with counterbores for facilitating screwing, the outer periphery of the two ends of the adjustment insertion rod is provided with threads, the first adjustment insertion hole is a threaded hole matched with the adjustment insertion rod, and the first adjustment insertion hole is throughly arranged on the mounting base, and the adjustment insertion rod is axially moved by threaded feeding movement.

[0017] Further, the guide mechanism further comprises an anti-reverse assembly, the anti-reverse assembly comprises a blocking member movably arranged on the limiting assembly, a blocking side wall arranged on the side of the blocking member facing the conveying channel and used for blocking the backflow of the cigarette case, a sinking inclined surface arranged on the side of the blocking member facing the gluing device and used for enabling the blocking member to be pushed by the cigarette case to retract into the limiting assembly, and an elastic reset member arranged below the blocking member and used for pushing the blocking member to protrude out of the limiting assembly.

[0018] Further, the first conveying belt and the second conveying belt are arranged oppositely, the first conveying belt is used for contacting and limiting the upper end adhesive joint of the cigarette case, and the second conveying belt is used for contacting and limiting the lower end adhesive joint of the cigarette case.

[0019] The cigarette case conveying device has the following beneficial effects:

[0020] 1. The cigarette case can enter the conveying channel along the guide channel, and is conveyed into the next process equipment or the warehouse by moving in the conveying channel under the driving of the first conveying belt and the second conveying belt. By selecting the quick-drying glue, the cigarette case can be kept in the state that the joint is adhered to the case paper tightly under the limiting of the guide mechanism and the first conveying belt and the second conveying belt during the conveying process until the joint is solidified and dried, and then enters the next process equipment or the warehouse, so that the quality defect of the joint unfolding of the newly coated cigarette case during the conveying process to the next process equipment or the warehouse can be effectively avoided.

[0021] 2. The cigarette case can be driven to move in the conveying channel by the first conveying belt and the second conveying belt, so that the time of the cigarette case to reach the next process equipment or the warehouse is shorter, and the conveying efficiency of the cigarette case can be significantly improved under the premise of using the quick-drying glue to ensure that the joint of the cigarette case can be quickly shaped.

[0022] 3. On the basis of the first conveying belt and the second conveying belt arranged oppositely to jointly limit the conveying of the cigarette case, the guide mechanism is arranged between the entrance of the conveying channel and the outlet of the glue coating equipment, and the guide mechanism is used to limit the joint of the cigarette case coming out of the glue coating equipment for the first time, so that the problem of the joint unfolding of the cigarette case before the joint glue is completely solidified and the cigarette case enters the conveying channel can be effectively prevented.

[0023] 4. Since the height dimensions of different cigarette cases cannot be completely consistent, the guide mechanism includes two limiting assemblies arranged oppositely, and the limiting main plates of the two limiting assemblies are arranged in a flexible floating manner. In this way, for different cigarette cases with inconsistent dimensions (millimeter level size deviation), the limiting main plates can be self-adapted to abut against the joint end surface of the cigarette case under the elastic force of the elastic expansion piece, so that the cigarette case with large size deviation is prevented from being stuck in the guide channel, and the joint of the cigarette case with small size deviation is prevented from unfolding due to the gap between the joint end surface and the limiting main plate. In addition, in addition to the pulley position at the end of the conveying belt, the other regions of the first conveying belt and the second conveying belt are mainly the conveying belt itself, which has appropriate flexibility, and the joint end surfaces of different cigarette cases with inconsistent dimensions (millimeter level size deviation) can also be limited by the conveying belt in the conveying channel, so that the joint case paper adhering and shaping quality can be ensured.

[0024] 5. The limit mainboard can be adjusted as accurately as possible to a position close to the conveyor belt in the height direction but still unable to touch the conveyor belt through the height limit adjustment component, so that the cigarette box can enter the conveying channel more smoothly from the introduction channel, and can also effectively avoid the limit mainboard contacting the conveyor belt and causing friction damage.

[0025] 6. Under the premise that there are multiple cigarette boxes on the introduction mechanism, the blocking member can be pushed downward by the cigarette boxes to sink under the limit main board when the cigarette boxes enter the introduction channel, so as to facilitate the entry of the cigarette boxes; and when the cigarette boxes continue to move until they leave the top of the blocking member, and the cigarette boxes squeezed against each other automatically return to their original shape after the cigarette pushing assembly leaves, the blocking member will automatically bulge upward under the elastic force of the elastic reset member to prevent the cigarette boxes from undergoing restorative deformation and expansion in the direction opposite to the direction of entry of the cigarette boxes, causing the last cigarette box to be pushed back, thereby avoiding the problem of cigarette boxes being blocked at the entrance of the introduction channel due to the cigarette boxes being pushed out in the opposite direction.

[0044] In this specification, the orientation terms such as up, down, left, right, front, back, front face, back face, top, bottom, etc. mentioned or possibly mentioned are defined relative to the configuration shown in the drawings, and the words "inner" and "outer" refer to the direction towards or away from the geometric center of a particular component, which are relative concepts, so it is possible to change accordingly according to different positions and different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0045] Referring to Figures 1 to 8 , the cigarette case conveying device of the embodiment of the present application mainly comprises a first conveying belt 1, a second conveying belt 2, and an introduction mechanism 3. The first conveying belt 1 and the second conveying belt 2 are arranged oppositely and in parallel. The area between the first conveying belt 1 and the second conveying belt 2 is a conveying channel 4 for the passage of cigarette cases. The introduction mechanism 3 is arranged between the front end of the conveying channel 4 and the cigarette case outlet of the gluing equipment. The introduction mechanism 3 also comprises two limiting assemblies 31 arranged oppositely and in parallel. The area between the two limiting assemblies 31 is an introduction channel 32. The introduction mechanism 3 limits the first time of the cigarette case from the cigarette case outlet of the gluing equipment through the two limiting assemblies 31, and guides the cigarette case to enter the conveying channel 4 along the introduction channel 32, and then is conveyed to the next process equipment or the warehouse.

[0046] In the embodiment, the interval between the first conveying belt 1 and the second conveying belt 2 is equivalent to the height dimension of the cigarette case, and the interval between the two limiting assemblies 31 is also equivalent to the height dimension of the cigarette case; in this way, when the cigarette case is pushed into the conveying passage 4 along the guide passage 32 and transported and moved in the conveying passage 4, the upper and lower tab end faces of the cigarette case are always abutted and limited by the limiting assemblies 31 or the conveying belts, so that the tabbed paper at the upper and lower end faces of the cigarette case is tightly adhered to the cigarette case body until the tabbed glue completely solidifies, so as to ensure that the tab of the cigarette case will not be automatically opened during the process of being conveyed into the next process equipment or the cigarette warehouse, thereby ensuring the quality of the cigarette case.

[0047] It should be noted that, in the embodiment, the tabbed glue of the cigarette case is selected to be a quick-drying glue, and the solidification time of the selected quick-drying glue is less than the time length for the cigarette case to move in the conveying passage, so as to ensure that the tabbed glue of the cigarette case can completely solidify before the cigarette case is conveyed into the next process equipment or the cigarette warehouse without using any drying device.

[0048] In some embodiments, the limiting assembly 31 comprises a mounting base 332, a limiting main plate 311 and a limiting side plate 312, the limiting main plate 311 is horizontally fixed on the mounting base 332, and the limiting side plate 312 is installed on the left and right sides of the limiting main plate 311. Figure 3 In the shown orientation, the limiting side plate 312 is installed on the left and right sides of the limiting main plate 311, and the two limiting main plates 311 are matched with the two limiting side plates 312 respectively, so as to guide the cigarette case to be pushed out from the glue coating equipment and into the conveying passage 4, and prevent the cigarette case from falling out of the guide passage 32 to the left and right sides.

[0049] In addition, in order to ensure that the cigarette case can always maintain the state of being abutted and limited by the tab, so as to enter the guide passage 32 from the outlet of the glue coating equipment and enter the conveying passage 4 from the guide passage 32, and prevent the tab of the cigarette case from being naturally unfolded, Figure 2 In the shown orientation, the horizontal distance from the right end of the limiting main plate 311 to the cigarette case outlet of the glue coating equipment is less than the width dimension of one cigarette case, and the horizontal distance from the left end of the limiting main plate 311 to the inlet end of the conveying passage 4 is also less than the width dimension of one cigarette case, so as to ensure that the upper and lower tab end faces of the cigarette case are always abutted and limited by the limiting assemblies 31 or the conveying belts.

[0050] In some embodiments, please refer to Figure 3The lead-in mechanism 3 further comprises two mounting bases 332, each of which is used to movably arrange one limiting assembly 31. The upper limiting assembly 31 is movably arranged below the upper mounting base 332, and the lower limiting assembly 31 is movably arranged above the lower mounting base 332. The upper limiting assembly 31 is vertically movable relative to the upper mounting base 332, and the lower limiting assembly 31 is vertically movable relative to the lower mounting base 332. Thus, the height of the lead-in channel 32 is adjustable, so as to be suitable for the cigarette boxes with different heights.

[0051] In some embodiments, referring to Figure 5 and Figure 6 , the upper limiting assembly 31 and the upper mounting base 332 are movably connected through an elastic expansion piece 314. Specifically, taking the lower limiting assembly 31 and the lower mounting base 332 as an example, the bottom of the limiting assembly 31 and the top end of the mounting base 332 are provided with connecting holes, the upper end of the elastic expansion piece 314 is fixedly connected with the limiting assembly 31 at the connecting holes, and the lower end of the elastic expansion piece 314 is fixedly connected with the mounting base 332 at the connecting holes. The limiting assembly 31 is vertically movable up and down under the elastic force of the elastic expansion piece 314, so as to be suitable for the cigarette boxes with different heights.

[0052] In some embodiments, the elastic expansion piece 314 is a spring.

[0053] In some embodiments, referring to Figure 5 and Figure 6 , taking the lower limiting assembly 31 and the lower mounting base 332 as an example, the lead-in mechanism 3 further comprises a height-limiting adjusting assembly 33, which comprises a sliding groove 331, a sliding rail 333, and an abutting limiting adjusting assembly 334. The sliding groove 331 is vertically arranged on the mounting base 332, the sliding rail 333 is fixedly arranged on the bottom of the limiting assembly 31, the sliding rail 333 is slidingly inserted into the sliding groove 331, and the abutting limiting adjusting assembly 334 is arranged between the sliding rail 333 and the sliding groove 331. In this way, the limiting assembly 31 can be vertically moved up and down by vertically sliding the sliding rail 333 in the sliding groove 331, so as to avoid the shaking of the limiting assembly 31 during the vertical movement, thereby affecting the conveying of the cigarette boxes. In addition, the abutting limiting adjusting assembly 334 is used to adjust the lowest sliding position of the sliding rail 333 in the sliding groove 331, so as to prevent the limiting assembly 31 from being moved too low to contact the first conveying belt 1 and be abraded.

[0054] In some embodiments, in order to achieve the above-mentioned function of adjusting the lowest sliding position of the sliding rail 333 in the sliding groove 331, referring to Figure 7The abutting limiting and adjusting assembly 334 includes a first adjusting insertion hole 3341, a second adjusting insertion hole 3342, an adjusting insertion rod 3343, and a limiting insertion pin. The first adjusting insertion hole 3341 is arranged on the mounting base 332 in a horizontal direction from the sliding groove 331. The second adjusting insertion hole 3342 is arranged on the sliding rail 333. The second adjusting insertion hole 3342 is a strip-shaped through hole or a circular through hole with a diameter larger than that of the adjusting insertion rod 3343, which is arranged on the sliding rail 333 in a vertical direction and is used to movably accommodate the adjusting insertion rod 3343. The adjusting insertion rod 3343 is inserted from one end of the first adjusting insertion hole 3341, extends into the second adjusting insertion hole 3342, and is then inserted into the other end of the first adjusting insertion hole 3341. The limiting insertion pin 3344 is horizontally inserted into the second adjusting insertion hole 3342, but the limiting insertion pin 3344 and the adjusting insertion rod 3343 are arranged above and below each other. The rod body part of the adjusting insertion rod 3343 exposed in the second adjusting insertion hole 3342 has a circular truncated cone section 3345 with a diameter gradually decreasing to the right. The limiting insertion pin 3344 is specifically blocked below the circular truncated cone section 3345.

[0055] In this way, the adjusting insertion rod 3343 can be axially moved by the technician, so that the limiting insertion pin 3344 abuts and contacts different diameter positions of the circular truncated cone section 3345, thereby adjusting the different lowest sliding positions of the sliding rail 333, and further flexibly adapting the first conveying belt 1 installed at different positions, so as to ensure that the limiting assembly 31 does not contact the first conveying belt 1 at all times when moving up and down.

[0056] In some embodiments, the diameter of the circular truncated cone section 3345 can also be gradually increased to the right.

[0057] In some embodiments, in order to facilitate the axial movement of the adjusting insertion rod 3343, cross recesses for easy screwing are arranged at both ends of the adjusting insertion rod 3343. The outer periphery of both ends of the adjusting insertion rod 3343 is also provided with threads. The first adjusting insertion hole 3341 is a threaded hole matched with the adjusting insertion rod 3343, or both ends of the first adjusting insertion hole 3341 are provided with internal threads. In this way, the technician can use a screwdriver or other tools to screw the adjusting insertion rod 3343, thereby moving the adjusting insertion rod 3343 axially.

[0058] In some embodiments, the guide-in mechanism 3 further includes a reverse prevention assembly 34. Please refer to Figure 8For example, the limiting assembly 31 has an opening on the limiting main plate 311, the anti-reverse assembly 34 includes a blocking piece 341 hingedly connected to the mounting base 313 of the limiting assembly 31, the other end of the blocking piece 341 is provided with an upward protrusion, the other end of the blocking piece 341 extends to the opening of the limiting main plate 311, the side of the protrusion of the blocking piece 341 facing the conveying channel 4 is vertically provided with a blocking side wall 342 for blocking the back movement of the cigarette case, the side of the protrusion of the blocking piece 341 facing the gluing device is obliquely provided with a sinking slope 343 for being pushed by the cigarette case to make the blocking piece 341 rotate downward, and then the protrusion of the blocking piece 341 is retracted downward into the gap between the limiting main plate 311 and the mounting base 313, and the mounting base 313 is also vertically provided with an elastic reset piece 344, the lower end of the elastic reset piece 344 abuts against the bottom end of the protrusion of the blocking piece 341.

[0059] For example, when the cigarette case is conveyed into the guide channel 32 and passes above the blocking piece 341, the protrusion of the blocking piece 341 will be retracted downward under the pushing action of the cigarette case, so as to facilitate the movement of the cigarette case, and when the cigarette case moves to the left side of the blocking piece 341, the blocking piece 341 will automatically swing back up under the elastic force of the elastic reset piece 344, the protrusion of the blocking piece 341 again extends to the limiting main plate 311, at this time, the blocking side wall 342 can block the back movement of the cigarette case under the pushing of the cigarette case on the right side of the blocking side wall 342. Figure 8

[0060] In some embodiments, the elastic reset piece 344 is also a spring.

[0061] It should be noted that the connection mode between the limiting assembly 31 and the mounting base 332 is exactly the same as the connection mode between the limiting assembly 31 and the mounting base 332, except that one is upwardly arranged and the other is downwardly arranged, so the connection structure principle between the limiting assembly 31 and the mounting base 332, and how the limiting assembly 31 adjusts the height through the height limiting adjustment assembly 33 to ensure that it can vertically and elastically move while avoiding the second conveying belt 2 will not be described again.

[0062] The above-mentioned matters not mentioned are applicable to the prior art.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.​
