Description

Technical Field

[0001] The invention relates to the technical field of cigarette box manufacturing and conveying equipment, and in particular to a cigarette box conveying channel. Background Art

[0002] A Chinese invention patent with publication number CN118892975A discloses a cigarette box drying channel, comprising two upper and lower parallel pressing plates, the pressing surfaces of the pressing plates being provided with rectangular mounting grooves, the mounting grooves being provided with heating devices, the cigarette box being moved between the two pressing plate brackets so that the upper overlap of the cigarette box is moved through the heating device of the upper pressing plate and the lower overlap is moved through the heating device of the lower pressing plate, so that the overlap glue is dried and solidified, preventing the cigarette box from expanding and deforming before the overlap glue is dried and solidified, resulting in a quality defect in which the overlap of the cigarette box is still expanded after gluing.

[0003] However, the above device still has the following defects: 1. The movement of cigarette boxes between the two pressing plates can only be achieved by the pushing of the cigarette boxes that enter later, that is, only when a cigarette box enters the pressing plate can the cigarette box that has entered between the pressing plates move under the push of the cigarette box that enters later. When no cigarette box enters, the cigarette box cannot move. The transportation efficiency of the cigarette box in the drying channel is low, so that the drying channel can only be used to dry the overlapping glue at the overlapping joints of the cigarette boxes, and cannot be used to transport the cigarette boxes to the next process equipment at the same time.

[0004] 2. In actual production, in order to ensure the production efficiency of cigarette box transportation, the operation of transferring the cigarette boxes from the gluing equipment into the drying channel is usually implemented by a conveyor belt device or a cigarette pushing component, that is, the conveyor belt device directly transports the cigarette boxes one by one to the drying channel, or the cigarette pushing component directly pushes the cigarette boxes one by one into the drying channel; however, in the process of the cigarette boxes being transported by the conveyor belt device or sent into the drying channel by the cigarette pushing component, since the overlapping glue on the cigarette boxes has not yet dried and solidified during this process, and the overlapping of the cigarette boxes has not been limited during this process, the cigarette boxes are more likely to have the phenomenon of unfolding the overlapping before entering the drying channel, and the cigarette boxes with unfolded overlapping will be blocked at the entrance of the drying channel because their shape does not match the drying channel, which greatly increases the risk of the cigarette boxes being blocked at the entrance of the drying channel.

[0005] 3. When the running speed of the conveyor belt device or the cigarette pushing component exceeds the drying speed of the drying channel, one or two cigarette boxes will accumulate at the entrance of the drying channel, which will cause the risk of cigarette box transportation being blocked, resulting in the drying channel being unable to flexibly and effectively deal with the problem of cigarette boxes blocking the entrance of the drying channel.

[0006] 4. When the newly glued cigarette boxes are pushed into the drying channel, the cigarette boxes 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 will be directly scrapped, and the cigarette boxes with a small degree of deformation may be restored to their original state. When these cigarette boxes are restored to their original state, 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 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

[0007] The present invention provides a cigarette box conveying channel, wherein an introduction mechanism is arranged at the front end of the conveying channel to form an introduction channel connecting the conveying channel and a cigarette box outlet of a gluing device, thereby effectively preventing the overlap of the cigarette box from opening before the glue is dried and solidified, 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.

[0008] The technical solution of the present invention to solve the above-mentioned problem is: to provide a cigarette box conveying device, the cigarette box conveying device 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, an introduction channel is provided between the two limit assemblies, the introduction channel is used to guide the cigarette box from the gluing device into the conveying channel, and the limit assembly is also used to contact the adhesive box paper at the end surface overlap of the limit cigarette box.

[0009] Furthermore, the limit assembly includes a limit main board, which is arranged at the lower edge or upper edge of the conveying channel, and the distance from the end of the limit main board to the entrance end of the conveying channel is less than the width of a cigarette box, and the introduction channel is the area between two limit main boards arranged opposite to each other up and down, and the limit assembly limits the adhesive box paper by making the limit main board abut against the end overlap of the cigarette box.

[0010] 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 arranged 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 fixedly mounted on the mounting base.

[0011] Furthermore, the introduction mechanism also includes a mounting base, and the limiting assembly is vertically movably arranged on the mounting base. The limiting assembly moves relative to the mounting base to adjust the size of the introduction channel, thereby adapting to abutting cigarette boxes of different height sizes.

[0012] Furthermore, an elastic telescopic member is provided between the position-limiting assembly and the mounting base, and the position-limiting assembly can elastically and adaptively move up and down relative to the mounting base through the elastic telescopic member, thereby automatically adapting to cigarette boxes of different heights and sizes.

[0013] Furthermore, the introduction mechanism also includes a height limit adjustment component for limiting the height position of the limit component; the height limit adjustment component includes a slide groove vertically opened on the mounting base, a slide rail arranged at the bottom of the limit main board, and an abutment limit adjustment component, the slide rail is vertically slidably arranged in the slide groove, and the abutment limit adjustment component limits the highest active position of the limit component arranged above or limits the lowest active position of the limit component arranged below by limiting the sliding stroke of the slide rail.

[0014] Furthermore, the abutment limit adjustment component includes a first adjustment hole opened on the mounting base, a second adjustment hole opened on the slide rail, an adjustment rod inserted into the first adjustment hole and the second adjustment hole at the same time, and a limit pin inserted on the slide rail. The adjustment rod is also provided with a frustum section whose diameter gradually increases or decreases along the axial direction. The adjustment rod moves axially so that positions with different diameters on its frustum section abut against and limit each other with the limit pin, so as to adjust the highest slidable position of the slide rail of the limit assembly above the limit, or adjust the lowest slidable position of the slide rail of the limit assembly below the limit.

[0015] Furthermore, countersunk holes for easy screwing are provided at both ends of the adjusting rod, threads are provided on the outer circumference of both ends of the adjusting rod, the first adjusting hole is a threaded hole adapted to the adjusting rod, and the first adjusting hole is arranged through the mounting base, and the adjusting rod moves axially through threaded feeding motion.

[0016] Furthermore, the introduction mechanism also includes an anti-reversal component, which includes a blocking member retractably arranged on the limiting component, a blocking side wall arranged on the side of the blocking member facing the conveying channel and used to prevent the cigarette box from retreating, a sinking inclined surface arranged on the side of the blocking member facing the glue coating device and used to allow the blocking member to be pushed by the cigarette box to retract into the limiting component, and an elastic reset member arranged below the blocking member and used to push the blocking member to extend out of the protrusion on the limiting component.

[0017] Furthermore, the first conveyor belt and the second conveyor belt are arranged opposite to each other up and down, the first conveyor belt is used to contact the upper adhesive overlap of the limiting cigarette box, and the second conveyor belt is used to contact the lower adhesive overlap of the limiting cigarette box.

[0018] The cigarette box conveying device of the present invention has the following beneficial effects: 1. The cigarette box can enter the conveying channel along the introduction channel, and move in the conveying channel driven by the first conveyor belt and the second conveyor belt, so as to be quickly conveyed to the next process equipment or cigarette warehouse; by selecting quick-drying glue, the cigarette box can keep the overlapping paper in a tight state during the conveying process under the limiting effect of the introduction mechanism, the first conveyor belt and the second conveyor belt until the overlapping glue solidifies and dries, and then enters the next process equipment or cigarette warehouse, so as to effectively avoid the quality defect of the newly glued cigarette box spreading out during the process of being conveyed to the next process equipment or cigarette warehouse.

[0019] 2. The cigarette box can be actively moved by the first conveyor belt and the second conveyor belt in the conveying channel, and the time it takes to reach the next process equipment or cigarette warehouse is shorter. Under the premise of using quick-drying glue to ensure that the overlap of the cigarette box can be quickly shaped, the efficiency of cigarette box transportation can be significantly improved.

[0020] 3. On the basis of the first conveyor belt and the second conveyor belt which are arranged relatively to each other up and down to jointly limit the conveying of cigarette boxes, an introduction mechanism is provided between the entrance of the conveying channel and the exit of the gluing device, and the introduction mechanism is used to limit the overlap of the cigarette boxes coming out of the gluing device at the first time, so as to effectively prevent the problem of the overlap of the cigarette boxes from expanding before the overlap glue is completely solidified and the cigarette boxes have not entered the conveying channel.

[0021] 4. Since the height dimensions of different cigarette boxes cannot be completely consistent, the introduction mechanism includes two upper and lower relative limit assemblies, and the limit mainboards of the two limit assemblies are both elastically floatingly arranged; in this way, for different cigarette boxes with different sizes (millimeter-level size deviation), the limit mainboard can be adaptively pressed against the overlap end face of the cigarette box under the elastic force of the elastic telescopic member, so as to avoid the cigarette box with larger size being stuck in the introduction channel, and also avoid the overlap of the cigarette box being unfolded due to the gap between the overlap end face of the cigarette box with smaller size and the limit mainboard. In addition, except for the pulley position at the end of the conveyor belt, the other areas of the first conveyor belt and the second conveyor belt are mainly the conveyor belt itself, which has appropriate flexibility, and the overlap end faces of different cigarette boxes with different sizes (millimeter-level size deviation) can also be abutted and limited by the conveyor belt in the conveying channel to ensure the quality of the bonding and shaping of the overlap box paper.

[0022] 5. The limit mainboard can be adjusted as accurately as possible to a position that is close to the conveyor belt in the height direction but still cannot touch the conveyor belt through the height limit adjustment component, so that the cigarette box can enter the conveying channel from the introduction channel more smoothly, and it can also effectively avoid the limit mainboard contacting the conveyor belt and causing friction damage.

[0023] 6. On the premise that there are multiple cigarette boxes on the introduction mechanism, the blocking member can be pushed downward by the cigarette box to sink under the limit main board when the cigarette box enters the introduction channel to facilitate the entry of the cigarette box; and when the cigarette box continues to move until it leaves the top of the blocking member and the cigarette boxes squeezed against each other automatically return to their original state after the cigarette pushing component leaves, the blocking member will automatically bulge upward under the elastic force of the elastic reset member to prevent the cigarette box from restoring and expanding in the direction opposite to the direction in which the cigarette box enters, causing the last cigarette box to be pushed back, thereby avoiding the problem of the cigarette box being blocked at the entrance of the introduction channel due to the cigarette box being pushed out in reverse.

DETAILED DESCRIPTION

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0027] See also Figures 1 to 8 A cigarette box conveying device according to a specific embodiment of the present invention mainly comprises a first conveyor belt 1, a second conveyor belt 2, and an introduction mechanism 3. The first conveyor belt 1 and the second conveyor belt 2 are arranged opposite to each other and in parallel. The area between the first conveyor belt 1 and the second conveyor belt 2 is a conveying channel 4 for cigarette boxes to pass through. The introduction mechanism 3 is arranged between the front end of the conveying channel 4 and the cigarette box outlet of the gluing device. The introduction mechanism 3 also comprises two limit assemblies 31 arranged opposite to each other and in parallel. The area between the two limit assemblies 31 is an introduction channel 32. The introduction mechanism 3 uses the two limit assemblies 31 to limit the cigarette boxes at the cigarette box outlet of the gluing device in the first time, and guides the cigarette boxes along the introduction channel 32 into the conveying channel 4, and then transported to the next process equipment or cigarette warehouse.

[0028] In this embodiment, the spacing between the first conveyor belt 1 and the second conveyor belt 2 is equivalent to the height dimension of the cigarette box, and the spacing between the two limit assemblies 31 is also equivalent to the height dimension of the cigarette box; in this way, when the cigarette box is pushed into the conveying channel 4 along the introduction channel 32 and is transported and moved by the conveyor belt in the conveying channel 4, the upper and lower overlapping end surfaces of the cigarette box are always tightly limited by the limit assemblies 31 or the conveyor belt, so that the adhesive box paper at the upper and lower end surfaces of the cigarette box is tightly bonded to the cigarette box body until the overlapping glue is completely solidified, so as to ensure that the cigarette box overlap will never open automatically during the process of being conveyed into the next process equipment or cigarette warehouse, thereby ensuring the quality of the cigarette box.

[0029] It should be noted that: in this embodiment, the adhesive glue at the joint of the cigarette box is quick-drying glue, and the setting time of the selected quick-drying glue is less than the time taken for the cigarette box to move in the conveying channel, so as to ensure that the adhesive glue at the joint of the cigarette box can be completely solidified before the cigarette box is conveyed to the next process equipment or cigarette warehouse without using any drying device.

[0030] In some embodiments, the limiting assembly 31 includes a mounting base 332, a limiting main board 311, and a limiting side board 312. The limiting main board 311 is horizontally fixed on the mounting base 332. Figure 3 Taking the shown orientation as an example, the limiting side plates 312 are installed on the left and right sides of the limiting main board 311, and the two limiting main boards 311 cooperate with the two limiting side plates 312 to guide the cigarette box to be pushed out from the gluing equipment and enter the conveying channel 4, and prevent the cigarette box from falling out of the introduction channel 32 to the left and right sides.

[0031] In addition, in order to ensure that the cigarette box can always keep the overlap in the state of being abutted and limited, so as to enter the introduction channel 32 from the outlet of the glue coating device and enter the conveying channel 4 from the introduction channel 32, and prevent the overlap of the cigarette box from spreading naturally, Figure 2 Taking the shown orientation as an example, the horizontal distance from the right end of the limiting main board 311 to the cigarette box outlet of the gluing device is less than the width of a cigarette box, and the horizontal distance from the left end of the limiting main board 311 to the entrance end of the conveying channel 4 is also less than the width of a cigarette box, so as to ensure that the upper and lower overlapping end surfaces of the cigarette box are always abutted and limited by the limiting component 31 or the conveyor belt.

[0032] In some embodiments, see Figure 3The introduction mechanism 3 also includes a mounting base 332, and the mounting base 332 is provided with two. The two mounting bases 332 are respectively used to movably set a limiting component 31, that is, the upper limiting component 31 is movably installed below the upper mounting base 332, and the lower limiting component 31 is movably installed above the lower mounting base 332. The upper limiting component 31 can move vertically relative to the upper mounting base 332, and the lower limiting component 31 can move vertically relative to the lower mounting base 332, so that the height dimension of the introduction channel 32 is adjustable, so as to adapt to cigarette boxes of different height dimensions.

[0033] In some embodiments, see Figure 5 and Figure 6 The upper limiting component 31 and the upper mounting base 332, as well as the lower limiting component 31 and the lower mounting base 332 are movably connected through the elastic telescopic member 314; specifically, taking the lower limiting component 31 and the lower mounting base 332 as an example, the bottom of the limiting component 31 and the top of the mounting base 332 are provided with connecting holes and grooves, the upper end of the elastic telescopic member 314 is fixedly connected to the limiting component 31 at the limiting hole and groove, and the lower end of the elastic telescopic member 314 is fixedly connected to the mounting base 332 at the limiting hole and groove, and the limiting component 31 floats up and down under the elastic force of the elastic telescopic member 314, so as to adapt to and match cigarette boxes of different heights.

[0034] In some embodiments, the elastic member 314 is a spring.

[0035] In some embodiments, see Figure 5 and Figure 6 , taking the lower limiting assembly 31 and the lower mounting base 332 as examples, the introduction mechanism 3 also includes a height limiting adjustment assembly 33, the height limiting adjustment assembly 33 includes a slide groove 331, a slide rail 333, and an abutting limiting adjustment assembly 334, wherein the slide groove 331 is vertically opened on the mounting base 332, the slide rail 333 is fixedly arranged at the bottom of the limiting assembly 31, the slide rail 333 is slidably inserted in the slide groove 331, and the abutting limiting adjustment assembly 334 is arranged between the slide rail 333 and the slide groove 331; in this regard, the limiting assembly 31 can guide the limiting assembly 31 to float vertically up and down by making the slide rail 333 slide vertically in the slide groove 331, so as to avoid the limiting assembly 31 from shaking during the floating process, thereby affecting the cigarette box transportation; in addition, the abutting limiting adjustment assembly 334 is used to adjust the lowest sliding position of the slide rail 333 in the slide groove 331, so as to prevent the limiting assembly 31 from moving too low downward and contacting the first conveyor belt 1, resulting in wear.

[0036] In some embodiments, to achieve the function of adjusting the lowest sliding position of the slide rail 333 in the slide slot 331, refer to Figure 7, taking the lower limit assembly 31 and the lower mounting base 332 as examples, the abutment limit adjustment assembly 334 includes a first adjustment socket 3341, a second adjustment socket 3342, an adjustment plug rod 3343, and a limit pin. The first adjustment socket 3341 is horizontally arranged on the mounting base 332 from the slide groove 331, and the second adjustment socket 3342 is arranged on the slide rail 333. The second adjustment socket 3342 is a bar-shaped through hole for movably accommodating the adjustment plug rod 3343 and vertically arranged on the slide rail 333, or a bar-shaped through hole with a diameter larger than the adjustment plug rod 3343. The adjusting rod 3343 is inserted from one end of the first adjusting hole 3341, extends into the second adjusting hole 3342, and then is inserted into the other end of the first adjusting hole 3341. The adjusting pin 3344 is horizontally inserted in the second adjusting hole 3342, but the adjusting pin 3344 and the adjusting rod 3343 are arranged to block each other up and down. The rod body portion of the adjusting rod 3343 exposed in the second adjusting hole 3342 has a frustum section 3345 whose diameter gradually decreases to the right, and the adjusting pin 3344 is specifically blocked below the frustum section 3345.

[0037] In this way, the technician can axially move the adjustment rod 3343 to make the adjustment pin 3344 abut against positions of different diameters of the conical section 3345, thereby adjusting the limiting slide rail 333 to have different minimum sliding positions, and then flexibly adapting the first conveyor belt 1 installed at different positions to ensure that the limit assembly 31 will never contact the first conveyor belt 1 when moving up and down.

[0038] In some embodiments, the diameter of the frustum segment 3345 may also be gradually increased toward the right.

[0039] In some embodiments, in order to facilitate the axial movement of the adjustment rod 3343, cross countersunk holes for easy screwing are provided at both ends of the adjustment rod 3343, and threads are also provided on the outer circumferences of both ends of the adjustment rod 3343. The first adjustment hole 3341 is a threaded hole adapted to the adjustment rod 3343, or internal threads are provided at both ends of the first adjustment hole 3341; in this way, technicians can use tools such as screwdrivers to screw the adjustment rod 3343, thereby moving the adjustment rod 3343 axially.

[0040] In some embodiments, the introduction mechanism 3 further includes an anti-reversal component 34, see Figure 8The cam 342 is a block 341 which is provided on the top of the cam 343 and is used to block the cam 343. The cam 342 is a block 341 which is used to block the cam 343.

[0041] In this regard, Figure 8 Taking the position shown as an example, when a cigarette box is transported into the introduction channel 32 and passes over the blocking member 341, the protrusion of the blocking member 341 will retract downward under the push of the cigarette box to facilitate the movement of the cigarette box. When the cigarette box moves to the left side of the blocking member 341, the blocking member 341 will automatically swing back to its original position upward under the elastic force of the elastic reset member 344, and the protrusion of the blocking member 341 will extend out to the limit main board 311 again. At this time, the blocking side wall 342 can prevent the cigarette box from retreating under the squeeze of the cigarette box on its right.

[0042] In some embodiments, the elastic return member 344 is also a spring.

[0043] It should be noted that the connection method between the upper limit assembly 31 and the upper mounting base 332 is exactly the same as the connection method between the lower limit assembly 31 and the lower mounting base 332, except that one is set upward and the other is set downward. Therefore, the connection structural principle between the upper limit assembly 31 and the upper mounting base 332 and how the upper limit assembly 31 uses the height limit adjustment assembly 33 to ensure that it can move vertically elastically while avoiding the second conveyor belt 2 will not be described in detail.

[0044] Anything not mentioned above is applicable to the prior art.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; 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 invention.
