Description

Technical Field

[0001] The invention relates to marking on special materials, in particular to a packaging carton paperboard and a production device thereof. Background Art

[0002] At present, packaging cartons are basically marked by laser marking machines. When marking, the packaging cartons are folded into packaging cartons and laser-marked while being conveyed by the conveyor belt of the laser marking machine. After the assembly line is marked, they are stacked and conveyed. Finally, when they reach the hands of customers and need to be used, the folded packaging cartons are unfolded to become packaging cartons for packaging. At present, because packaging cartons are placed in stacks, it is necessary to manually place the cartons on the stack of packaging cartons one by one on the conveyor belt, which is very inefficient and labor-intensive, resulting in high labor costs. The prior art also has laser marking machines that reduce labor, such as the patent with publication number CN211162462U: carton laser marking machine. In actual use, the operator pries open the vertical board and places the carton to be marked on the side of the loading baffle close to the carton transfer device. The linear drive device on the No. 1 frame drives the loading baffle to press the carton onto the transfer bracket; the suction cup inhales the vacuum to suck the carton; the transfer power component drives the suction cup assembly to move the suction cup bracket close to the feeding device to the position of the marking unit, the suction cup breaks the vacuum, and the pressing cylinder presses the carton onto the transfer bracket, and the marking unit marks the carton; at the same time, the suction cup bracket close to the unloading device is just located at the unloading device; when the marking unit marks the carton, the transfer power component drives the suction cup assembly to reset, and at this time the two suction cup brackets The rack is divided into two parts, one is located at the feeding device and the other is located at the marking unit. After the marking unit completes marking, the clamping cylinder releases the carton, and the suction cup absorbs the vacuum to suck the marked carton and the carton at the feeding device. The transplanting power assembly drives the suction cup assembly to bring the carton at the feeding device to the marking unit position, and at the same time, the carton that has been marked at the original marking unit is brought to the unloading device. After the carton arrives at the unloading device position, the suction cup breaks the vacuum, and the clamping cylinder on the third rack presses the carton on the baffle plate. Since the baffle cylinder and the carton simultaneously generate thrust on the baffle plate, the baffle plate rotates around the hinge shaft. When the baffle plate passes through one end of the rectangular slot on the unloading hinge plate and is parallel to the unloading hinge plate, the carton is pushed to the unloading baffle plate by the clamping cylinder, and the thrust of the carton on the baffle plate disappears, and the baffle plate is reset under the action of the baffle cylinder. Although it reduces labor and enables the transfer and marking of cartons and paperboards one by one, it requires vacuum suction cups to adsorb them one by one and then transport them to the unloading place for unloading, which makes the entire mechanism complicated and the operation process cumbersome. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects existing in the prior art and provide a packaging carton paperboard, which mainly improves the structure of the production equipment so that the carton paperboard stacks do not need to be separated one by one manually, and cooperates with the conveying auxiliary structure on the packaging carton paperboard to better ensure separation and conveying.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is to design a packaging carton paperboard, including a carton connected end to end, and provided with four mutually parallel folds arranged along the length direction of the carton paperboard; the carton paperboard is folded along two diagonal folds of the carton to form a carton paperboard, and a conveying auxiliary structure is arranged on the carton paperboard to facilitate the conveying of the carton paperboard on the conveyor belt of the laser marking machine. By arranging the conveying auxiliary structure on the carton paperboard, it is convenient for the carton paperboard to be conveyed on the conveyor belt of the laser marking machine, the effectiveness of packaging conveying is improved, and the slipping phenomenon that occurs when light-weight carton paperboard is conveyed through the conveyor belt is avoided. In addition, the arrangement of the conveying auxiliary structure can also better ensure the separation of each carton paperboard in the carton paperboard pile.

[0005] A further technical solution is that the conveying auxiliary structure includes a plurality of convex points arranged at intervals on the outer surface of the carton paperboard. The convex points are arranged on the carton paperboard to achieve spacing between the stacked carton paperboards, so as to better ensure that each carton paperboard rises above the upper surface of the conveyor belt; in addition, it is also more convenient for the carton paperboard to be picked up on the conveyor belt to facilitate the conveyor belt to convey the carton paperboard to be marked; the arrangement of the conveying auxiliary structure avoids the problem that the too smooth surface of the carton paperboard is easy to slip when conveyed on the conveyor belt. In order to better achieve this effect, anti-slip patterns can also be set on the convex points.

[0006] A further technical solution is that an extended cardboard is integrally provided in the width direction of the cardboard to serve as the top surface or the bottom surface of the unfolded carton.

[0007] A further technical solution is that the convex points are made of solid paper, the hardness of which is higher than that of the carton paperboard. After such arrangement, the convex points will not be compressed and flattened due to the stacking of carton paperboards.

[0008] A further technical solution is that the ends of the protrusions away from the surface of the carton paperboard are provided with anti-slip grooves; the protrusions are in the shape of a trapezoid, a hemisphere or a frustum.

[0009] The technical solution also provided by the present invention is a device for producing packaging cartons and paperboards, wherein the device is a laser marking machine, a carton and paperboard stack is placed at the feeding end of the laser marking machine, a carton and paperboard stack placement place is set at the feeding end of the laser marking machine, and a carton and paperboard stack placement place is provided with a carton and paperboard single-portion conveying mechanism for the carton and paperboard stack. The cardboard of the packaging carton is folded to form a carton and paperboard, and the carton and paperboard stacks placed in piles constitute a carton and paperboard stack. The laser marking machine includes a machine body and a conveyor belt arranged outside the machine body, and the starting end of the conveyor belt is the feeding end. Through the setting of the lifting mechanism, the carton and paperboard stack is gradually lifted, and when the top carton and paperboard is lifted to exceed the upper surface of the conveyor belt, it can be pushed by the pushing device to achieve the top carton and paperboard reaching the conveyor belt for subsequent marking and conveying. Repeating this process can complete the transmission of cartons and paperboards one by one.

[0010] A further technical solution is that the carton paperboard conveying mechanism includes a lifting mechanism for the carton paperboard stack, the lifting mechanism includes a lead screw nut mechanism arranged on one side of the carton paperboard stack, and a support plate fixedly arranged on the nut of the lead screw nut mechanism and located below the carton paperboard stack; a photoelectric sensor is arranged above the conveyor belt in the height direction, the photoelectric sensor is arranged close to the carton paperboard stack and located on the outside of the carton paperboard stack, and the height of the photoelectric sensor is higher than the carton paperboard at the top of the carton paperboard stack at the beginning; the carton paperboard conveying mechanism also includes a cylinder arranged at the feeding end of the laser marking machine on the side of the carton paperboard stack away from the conveyor belt, the cylinder is connected to the controller signal, and the controller is connected to the photoelectric sensor signal. In terms of structure, only one conveyor belt and a lifting mechanism are required, and the action process is also simple. When the carton paperboard lifted by the lifting mechanism to the top is detected by the photoelectric sensor, it is pushed out to the conveyor belt by the cylinder, and then marked with the laser transmitter of the laser marking machine. After marking, it continues to be transmitted out of the laser marking machine body by the conveyor belt. When being pushed out, only one carton (that is, the top one each time) needs to overcome the static friction due to its own weight relative to the carton below it, so the thrust of the cylinder required is also small, that is, the energy consumption required is also small, and this method is effective and has a high success rate. It is extremely unlikely that the carton to be conveyed is not pushed out (that is, it is extremely unlikely that the cartons are not conveyed one by one).

[0011] The advantages and beneficial effects of the present invention are as follows: by arranging a conveying auxiliary structure on the carton paperboard, it is convenient to convey the carton paperboard on the conveyor belt of the laser marking machine, the effectiveness of packaging conveying is improved, and slipping when light-weight carton paperboard is conveyed through the conveyor belt is avoided. In addition, the arrangement of the conveying auxiliary structure can also better ensure the separation of each carton paperboard in the carton paperboard stack.

[0012] Convex points are set on the carton paperboard to achieve spacing between the stacked carton paperboards, which can better ensure that each carton paperboard rises above the upper surface of the conveyor belt; in addition, it is also more convenient for the carton paperboard to be picked up on the conveyor belt to facilitate the conveyor belt to transport the carton paperboard to be marked; the setting of the conveying auxiliary structure avoids the problem of too smooth carton paperboard surface slipping when conveyed on the conveyor belt. In order to better achieve this effect, anti-slip patterns can also be set on the convex points.

[0013] The convex points are made of solid paper, which has a higher hardness than the carton board. In this way, the convex points will not be pressed and flattened due to the stacking of carton boards.

[0014] The structure only requires a conveyor belt and a lifting mechanism, and the operation process is also simple. When the lifting mechanism lifts the top carton paperboard, it is detected by the photoelectric sensor and pushed onto the conveyor belt by the cylinder, and then the laser emitter of the laser marking machine is used for marking. After the marking is completed, it is continuously transmitted out of the laser marking machine body by the conveyor belt. When being pushed out, only one carton paperboard (that is, the top one each time) needs to overcome the static friction force of its own weight relative to the carton paperboard below it, so the required cylinder thrust is also small, that is, the required energy consumption is also small, and this method is effective and has a high success rate. It is very difficult for the carton paperboard to be transported to not be pushed out (that is, it is very difficult for the carton paperboard to not be transported one by one).

DETAILED DESCRIPTION

[0017] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0018] Embodiment 1: Figures 1 to 7 As shown (for ease of illustration, Figure 3 The column, slider and photoelectric sensor are not shown). The present invention is a packaging carton board, comprising a cardboard 1 connected end to end, and four mutually parallel folds 2 arranged along the length direction of the cardboard are arranged on the cardboard; the cardboard 1 is folded along two folds 2 at the diagonals of the carton to form a carton board, and a conveying auxiliary structure is arranged on the carton board to facilitate the conveying of the carton board on the conveyor belt of the laser marking machine; the conveying auxiliary structure is a plurality of convex points 3 arranged at intervals on the outer surface of the carton board; the convex points 3 are arranged on the carton board to achieve a spacing between the stacked carton boards (the convex points can be made of harder paper or solid paper to avoid being crushed), so as to better ensure that each time a carton board rises above the upper surface of the conveyor belt; in addition, it is also more convenient for the carton board to be picked up on the conveyor belt to facilitate the conveyor belt to convey the carton board to be marked; the provision of the conveying auxiliary structure avoids the problem that the too smooth surface of the carton board is easy to slip when conveyed on the conveyor belt. In order to better achieve this effect, anti-slip patterns can also be provided on the convex points 3. An extended paperboard 4 is also integrally provided in the width direction of the paperboard to serve as the top surface or the bottom surface of the unfolded carton.

[0019] The equipment for producing the packaging carton paperboard is a laser marking machine. A carton paperboard stack 5 is placed at the feeding end of the laser marking machine (referring to the starting end of the conveyor belt 6 of the laser marking machine) (the cardboard of the packaging carton is folded to form a carton paperboard, and the carton paperboards placed in stacks constitute the carton paperboard stack 5). The feeding end of the laser marking machine is provided with a carton paperboard stack 5 placement position, and the carton paperboard stack placement position is provided with a carton paperboard single-portion conveying mechanism, and the carton paperboard single-portion conveying mechanism includes a carton paperboard stack lifting mechanism, and the lifting mechanism includes a screw arranged on one side of the carton paperboard stack 5 A support plate 8 located below the carton paperboard stack is fixedly arranged on the nuts of the nut mechanism 7 and the lead screw nut mechanism, a slider 9 is fixedly connected to the side of the nut of the lead screw nut mechanism away from the carton paperboard stack 5, and the slider slides vertically on the column 10 (the lead screw nut mechanism 7, the slider 9 and the column 10 are arranged in sequence outward along the carton paperboard stack 5), the lead screw of the lead screw nut mechanism is connected to the output shaft of the reduction motor, and connecting blocks for the rotation of the lead screw are arranged at the upper and lower ends of the column, and another column 10 arranged opposite to the aforementioned column is also arranged on the other side of the carton paperboard stack 5. , a slide groove is arranged on the column 10 for the sliding of the pallet. In the initial stage, the top of the carton paperboard stack is lower than the upper surface of the conveyor belt 6. A photoelectric sensor 11 is arranged above the conveyor belt 6 of the laser marking machine. The photoelectric sensor 11 is arranged close to the carton paperboard stack (but still located above the conveyor belt) and located on one side of the carton paperboard stack. The photoelectric sensor is higher than the top of the carton paperboard stack (referring to the top of the carton paperboard stack that has not been lifted at the beginning); the feeding end of the laser marking machine is located at the carton paperboard A cylinder 12 is arranged on the side of the stack 5 away from the conveyor belt 6, and the cylinder is connected to the controller signal, and the controller is connected to the photoelectric sensor signal. When the lifting mechanism is actuated to lift the top carton paperboard of the carton paperboard stack until the photoelectric sensor senses it, the lifting mechanism stops moving, and the controller controls the cylinder 12 to move to push the top carton paperboard of the carton paperboard stack onto the conveyor belt 6; in this way, there is no need to manually place the carton paperboards on the packaging carton paperboard stack one by one onto the conveyor belt, which improves efficiency, saves labor, and reduces labor costs; Start the control system of the laser marking machine to mark according to the predetermined parameters and trajectory. The laser beam generated by the laser generator 13 is concentrated on a small point through the focusing system, and then the laser beam is controlled to scan the marking area through the scanning system (the principle of the laser marking machine is the existing technology and will not be repeated). After the conveyor belt receives the carton cardboard pushed out by the cylinder, the conveyor belt transports the carton cardboard to the laser marking machine body for marking. In this embodiment, a conveyor belt is provided inside and outside the body 14, and a large conveyor belt can also be used to penetrate the body. In this way, the opening 15 on the side of the body 14 needs to be larger to accommodate the conveyor belt and its frame and other components.

[0020] Embodiment 2: The difference from Embodiment 1 is that Figures 8 to 18 As shown ( Figure 8 A schematic diagram of a state in which the cardboard is blocked by the baffle and folded against the side of the carton cardboard; Fig.14 This is a schematic diagram of the state of the cardboard after it exceeds the upper surface of the belt; for the convenience of illustration, Fig.14 The lifting mechanism is not shown. An opening is set in the middle of the width direction of the conveyor belt. The carton and paperboard stack placement place is located below the opening. When the top cardboard of the carton and paperboard stack on the carton and paperboard stack placement place rises to exceed the conveyor belt, the conveyor belt and the middle opening are connected by a connecting piece to realize the conveying of the cardboard. In this embodiment, the carton and paperboard single-piece conveying mechanism only includes the carton and paperboard stack lifting mechanism. The single-piece carton and paperboard are conveyed by the screw nut mechanism in combination with the cardboard and elastic strip.

[0021] Or the conveyor belt includes a pair of pulleys (one is a driving wheel 16 and the other is a driven wheel 17) and two belts 18 wound around the pair of pulleys, a gap is set between the two belts, and the carton paperboard stack 5 is placed at the gap. After the top cardboard of the carton paperboard stack rises beyond the conveyor belt, the top cardboard is moved together with the belts on both sides through a connecting piece (that is, a conveying auxiliary structure) to realize automatic conveying, without manual separation one by one, avoiding manual separation and placement, reducing labor and improving efficiency; the conveying auxiliary structure includes elastic paper folded on both sides of the carton paperboard; or a more preferred solution is: the conveying auxiliary structure includes elastic paper folded on both sides of the carton paperboard A pair of folded paperboards 19, one end of the paperboard 19 is fixedly connected to the side of the carton paperboard, and the other end is a free end, and each paperboard 19 is fixedly provided with an elastic strip 20 on the outer side relative to the carton paperboard (or the auxiliary conveying structure still includes a plurality of spaced convex points arranged on the outer surface of the carton paperboard to ensure that there is a spacing between adjacent carton paperboards, that is, the auxiliary conveying structure of this embodiment can be further provided with the aforementioned elastic paper {or paperboard and elastic strip} on the basis of the first embodiment); the elastic strip 20 is smaller than the paperboard 19, one end of the elastic strip is fixedly connected to the surface of the paperboard 19, and the other end is fixedly connected to the side of the carton paperboard. After the cardboards of the carton cardboard stack rise to exceed the conveyor belt, the folded elastic paper on both sides of the carton cardboard (or the cardboard 19 due to the elastic force of the elastic strip 20) is unfolded outward, and at least two pairs of upwardly protruding rubber columns 21 are fixedly provided on the side of the belt 18 close to the spacing, and each pair of rubber columns 21 is located at the same position in the length direction of the belt 18. The side of the carton cardboard is also fixedly provided with a limiting cardboard block 22 for limiting the elastic paper (or for limiting the flipping angle of the cardboard 19); (Since the elastic paper or the elastic strip 20 is elastic and shrinkable, it can be put away during transportation or after the carton is unfolded to package items; and the limiting cardboard block 22 only needs to protrude slightly relative to the side of the carton cardboard to play the role of cardboard limiting, and then cooperate with the rubber column 21 to drive the carton cardboard to move with the belt, so the limiting cardboard block can be set to a smaller size, so it hardly occupies any space during transportation or after the carton is unfolded to package items). Although due to the setting of the cardboard block, due to the setting of the elastic strip, the cardboard can be folded up after being unfolded into a packaging carton so that the combination of the cardboard and the elastic strip can additionally cooperate to better keep the top surface or the bottom surface of the carton closed, and cooperate with the tape seal to better keep the top surface from cracking during transportation (although the prior art uses tape seals to keep the top and bottom surfaces from opening, sometimes the packaging carton is easily cracked or opened due to lateral compression, resulting in the tape seal sticking paper fibers on the top or bottom surface, but this embodiment can withstand greater extrusion pressure than the prior art due to the abutment of the elastic strip).As shown in the figure of this embodiment, only one side is provided with an extended cardboard, that is, the carton has only the top surface or the bottom surface, and the other side is an opening. At this time, the elastic strips and cardboard 19 in the opening can be subsequently cut off or folded as needed; and the elastic strips and cardboard 19 on the extended cardboard of the top surface or the bottom surface can be used as components to improve the side extrusion pressure that the packaging carton can withstand; therefore, the conveying auxiliary structure of the elastic strips and the cardboard not only assists in conveying, but also improves the lateral extrusion bearing capacity of the packaging carton.

[0022] A baffle can be fixedly connected to the inner wall of the side plate of the conveyor frame, and the size of the baffle is slightly smaller than the size of the inner ring formed by the endless belt 18, so that on the one hand it does not interfere with the movement of the belt, and on the other hand it can properly guide the carton paperboard lifted by the lifting mechanism. After the reduction motor in the lifting mechanism is started, the pallet gradually rises. When the top carton paperboard of the carton paperboard stack 5 on the pallet is lifted to a height exceeding the upper surface of the conveyor belt, that is, the belt, the cardboard originally folded against the side of the carton paperboard (or the cardboard blocked by the baffle) is no longer squeezed (of course, the fixed position and length of the elastic strip are selected to meet the elastic strip being in a tension state when the cardboard is folded against the side of the carton paperboard, and the elastic strip is still in a certain tension state after the cardboard abuts against the limiting cardboard block 22), the elastic strip is no longer tensioned and shrinks freely, thereby driving the cardboard to flip to an unfolded state, and the cardboard rotates until it abuts against the limiting cardboard block 22 and stops rotating. In the process of the belt moving with the rotation of the pulley, when the rubber column 21 moves to the "unfolded" cardboard, it can drive the carton paperboard to move with the belt.

[0023] A structure is set on the packaging carton paperboard so that the cartons placed in stacks can be automatically separated one by one when being conveyed on the conveyor belt, avoiding manual separation and placement, reducing labor and improving efficiency. Moreover, after the present embodiment is so set, the driving mechanism is reduced, and the conveying auxiliary structure combining elastic paper and rubber columns is used, only one lifting mechanism is required (the screw nut mechanism in the lifting mechanism is arranged on one side of the length direction of the carton paperboard stack 5, and the width of the carton paperboard stack 5 is slightly smaller than the spacing between the two belts 18) and the conveyor belt (the conveyor belt is the driving device required by the laser marking machine itself, and the objects to be marked are transmitted through the conveyor belt, and the laser generator in the machine body is used to realize marking on the objects, so it is equivalent to adding only one driving device, namely a lifting mechanism, and there are fewer control links). Unlike the first embodiment, it is necessary to set another cylinder to drive the top carton paperboard of the carton paperboard stack in order to cooperate with the conveyor belt to realize transmission. Before each stack of cartons and paperboards is placed between the two belts, two oppositely arranged flat plates are used to slide along the sides of the carton paperboards. This process ensures that the sides of each carton paperboard in the stack are folded and then placed between the two belts together with the flat plates (that is, the process of placing the carton paperboards on the two belts is also relatively simple. You only need to manually pick up two flat plates, slide them over the carton paperboards from the sides, clamp a stack of carton paperboards, and place the carton paperboards and the flat plates between the two belts. Then, take the flat plates upwards. Although there is no flat plate squeezing the paperboards at this time, there is a baffle fixedly connected to the side plate of the conveyor belt frame to block the paperboards).

[0024] Embodiment 3: The difference from Embodiment 1 is that Figures 19 to 22 As shown, the carton paperboard single-piece conveying mechanism only includes a cam mechanism 23, the cam of the cam mechanism is fixedly connected to the axle of the pulley of the conveyor belt 6 outside the laser marking machine body 14 through a flexible shaft 24 (to achieve the cam mechanism to intermittently push the carton paperboard at the bottom of the carton paperboard stack after the conveyor belt is running), and a pad 25 is set on the side of the conveyor belt 6 outside the body 14 away from the body (that is, at the feeding end of the laser marking machine), and the upper surface of the pad 25 is flush with the upper surface of the conveyor belt. The pad 25 is used to place the carton paperboard stack 5. A baffle 26 is fixedly set on the side of the carton paperboard stack 5 close to the body above the conveyor belt 6, and the distance between the lower edge of the baffle and the upper surface of the pad is equivalent to the thickness of a carton paperboard, so that when the cam mechanism pushes the carton paperboard at the bottom of the carton paperboard stack 5, it can avoid the embarrassment that the carton paperboard at the bottom brings out the carton paperboard above and falls on the conveyor belt together. The baffle 26 can be fixed on the frame of the conveyor belt or fixed on the two side blocks of the conveyor belt (for the convenience of illustration, Fig.19The stopper is removed. The stopper is an existing technology of the conveyor belt, which is used to prevent the conveyor belt from falling off the edge of the conveyor belt when conveying the items. It will not be described in detail). The cam mechanism includes a bottom plate 27, a cam 28 is rotatably arranged on the bottom plate, and a push rod 29 is slidably arranged on the bottom plate. The push rod 29 is equivalent to the length of the carton board on the carton board stack. One end of the push rod 29 is directly facing the carton board, and the other end is rotatably arranged with an intermediate wheel 30, which is arranged against the cam.

[0025] After such arrangement, only a driving mechanism such as a conveyor belt is needed, and the conveyor belt is the driving mechanism required by the laser marking machine itself, which is equivalent to not adding any driving mechanism. The operation of the conveyor belt drives the cam mechanism to operate, realizes the rotation of the cam, and drives the push rod to intermittently push the carton paperboard at the bottom of the carton paperboard stack, and each time the cam rotates one circle, it pushes a carton paperboard. When the cam pushes, the bottom carton paperboard is pushed onto the conveyor belt, and the carton paperboard stack falls on the push rod due to its own weight. Another baffle plate opposite to the baffle plate can be set on the other side of the carton paperboard stack, so that the push rod will not drive the carton paperboard away from the carton paperboard stack after it is reset.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
