Description

Technical Field

[0001] The present invention relates to the technical field of carton board processing, and in particular to a carton board processing and production device capable of stable transmission. Background Art

[0002] Cartons play a vital role in modern packaging and transportation. They are often used to pack and load various products. Cartons are made by cutting and folding carton boards.

[0003] For example, a carton board processing and production device with stable transmission and with announcement number "CN112847530B" is disclosed, which includes a door frame, a control column is arranged in the door frame, a ring blade is sleeved in the middle of the control column, an auxiliary shaft is arranged at the lower end of the control column, a blade slot and a rubber sleeve are fixedly sleeved on the auxiliary shaft, two symmetrically distributed rubber sleeves are arranged around the blade slot, a vertical plate is arranged at the end of the auxiliary shaft, and a control disk is fixedly connected to the auxiliary shaft. The structural design of the present invention realizes automatic control of the cardboard cutting process. When the cardboard is stationary, the door frame will not rotate, and the conveying mechanism drives the cardboard to move, automatically triggering the cardboard cutting and processing work, thereby realizing the automatic control disconnection effect of the transmission mechanism.

[0004] However, in the prior art, the processing of carton boards into cartons generally requires the main steps of printing, die-cutting, creasing, box gluing and folding. Among them, the carton boards need to be loaded before processing. At present, the loading methods of carton boards include manual loading or automatic loading. Usually, the carton boards are stacked up and down to a certain height and placed on a loading conveyor belt. The conveyor belt can be used to transport the carton boards, and the carton boards at the bottom can be moved away. The stacked carton boards are moved to the loading platform in turn in this way. However, in this process, the carton boards generally need to be stacked to a certain height, and the pressure on the bottom carton board will be greater. At this time, the friction between the bottom carton board and the penultimate carton board will be greatly increased. When the conveyor belt takes away the bottom carton board, if the friction between the conveyor belt and the carton board is too small, the conveyor belt may not be able to bring out the bottom carton board well, and it may slip, resulting in instability during loading and transmission, affecting the subsequent processing progress. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the conveyor belt cannot bring out the lowest carton board well, and it is easy to slip, resulting in instability during material feeding and transmission, affecting the subsequent processing progress.

By driving the first motor, the first gear is driven to rotate, and then the first gear is driven to mesh with the rack, so that the first gear moves in the annular groove, thereby driving the lifting plate to move along the annular groove as a moving trajectory, and when the lifting plate is in contact with the side wall of the cardboard, it moves upward to lift the cardboard pile a certain distance, thereby reducing the pressure on the bottom cardboard.

[0008] As a preferred embodiment, the first motor is arranged on a side frame away from the connecting strip, the rotating shaft is driven to rotate by the first motor, a limiting groove is provided on the inner side of the annular groove of the outer wall of the side frame, one side of the first motor is engaged and slidably connected with the limiting groove, and the first motor is driven to rotate, wherein the first motor is limited by the limiting groove, which can prevent the first motor from rotating when the first gear drives the first motor to move around the annular groove.

By setting the upper and lower groups of annular grooves, the stability of the lifting plate during the lifting process can be effectively guaranteed.

[0010] As a preferred embodiment, baffles are symmetrically provided on the workbench located on both sides of the feeding conveyor belt through brackets. The lower side of the baffle is in contact with the upper side of the feeding conveyor belt, and the inner side is in contact with the side wall of the cardboard. The height of the baffle is adapted to the height of a cardboard. By setting the baffles, the bottom layer of the cardboard is prevented from being moved upward when the lifting plate moves up, and only the upper cardboard is lifted.

The tooth plate is provided with two and the end faces are respectively assembled and connected to the outer walls of two adjacent right-angle frames. The two tooth plates are slidably arranged in the fixed box on opposite sides, and the second gear is rotatably arranged between the fixed boxes. The tooth plate is meshed with the second gear, and the second gear is driven to rotate by the second motor. By driving the second motor to rotate, the second gear is driven to rotate, and then the two tooth plates are driven to move in opposite directions synchronously, thereby driving the two adjacent right-angle frames to move in opposite directions synchronously, so as to achieve the adjustment of the internal range of the workbench.

[0015] As a preferred embodiment, the telescopic mechanism is provided with four ones which are respectively located between adjacent right-angle frames, and only one of the two telescopic mechanisms arranged opposite to each other is driven to rotate by the second motor.

[0017] 1. When the push plate pushes the lower cardboard and extends to the bottom of the penultimate cardboard, the push airbag is expanded to open a certain gap between the lowest cardboard and the second cardboard below. At the same time, the driving mechanism drives the lifting plate to move to all cardboard sides except the cardboard above the lowest cardboard and fits tightly. The driving mechanism drives the lifting plate to move up. The clamping cooperation of the two lifting plates can lift the cardboard pile as a whole by a certain distance. At this time, the pressure of the cardboard stacked on the upper side on the cardboard moving out of the lowest position can be greatly reduced, so that the friction between the feeding conveyor belt and the lowest cardboard is much greater than the friction between the adjacent cardboards below, so that the cardboard can smoothly follow the feeding conveyor belt to move out of the workbench, and stable transportation and stable transmission of the cardboard can be achieved.

[0018] 2. The present invention drives the second motor to rotate, thereby driving the second gear to rotate, and then driving the two tooth plates to move synchronously in the opposite direction, thereby driving the two adjacent right-angle frames to move synchronously in the opposite direction, so as to achieve the adjustment of the internal range of the workbench, so that the workbench is suitable for limited loading of cardboards of different sizes.

[0019] 3. When the lifting plate of the present invention moves downward, it can drive the push rod to move downward and extend into the fixed tube, pushing the original gas in the fixed tube into the push airbag, propping up the push airbag, and the propped-up push airbag pushes up the upper cardboard to create a gap.

[0020] 4. The present invention drives the first motor to rotate the first gear, which in turn drives the first gear to engage with the rack, so that the first gear moves in the annular groove, thereby driving the lifting plate to move along the annular groove as a moving trajectory.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When loading carton boards, the carton boards are stacked and placed between four right-angle frames 4, wherein the distance between the four right-angle frames 4 can be adjusted according to the length and width of the carton boards, and the adjusted distance between the four right-angle frames 4 is symmetrical. The inner wall of the right-angle frame 4 slides and fits with the edge of the cardboard. Under the action of gravity, the lowest cardboard falls on the feeding conveyor belt 2. When feeding, the feeding conveyor belt 2 is driven to rotate, and the pushing mechanism is driven to drive the push plate 7 to push back and forth. The driving mechanism is started to drive the lifting plate 9 to lift and lower. The lowest cardboard is pushed by the push plate 7 and slides between the upper cardboard. Under the action of the feeding conveyor belt 2, it gradually leaves the workbench 1, and the lower cardboard is discharged from the discharge chute 6. When the push plate 7 pushes the lower cardboard and extends to the bottom of the second to last cardboard, the top push airbag 8 is opened, so that the lowest and the lower cardboard are pushed back and forth. A certain gap is opened between the two cardboards. At the same time, the driving mechanism drives the lifting plate 9 to move to all the side edges of the cardboards except the top of the bottom cardboard and fit tightly. The driving mechanism drives the lifting plate 9 to move upward. The clamping cooperation of the two lifting plates 9 can lift the cardboard pile as a whole by a certain distance. At this time, the pressure of the cardboards stacked on the top on the cardboards moving out of the bottom can be greatly reduced, so that the friction between the feeding conveyor belt 2 and the bottom cardboard is much greater than the friction between the adjacent cardboards below, so that the cardboards can smoothly follow the feeding conveyor belt 2 to move out of the workbench 1, realizing stable transportation and stable transmission of the cardboards.

[0036] like Figure 1 - Fig.11 As shown, the driving mechanism includes a fixed frame 111, a side frame 112, a rotating shaft 113 and a first motor 114. The lower end of the fixed frame 111 is assembled and connected with the workbench 1. The side frame 112 is provided with two and symmetrically arranged on both sides above the fixed frame 111. An annular groove 115 is opened on the inner side of the side frame 112. A connecting strip 116 is provided on the side of the lifting plate 9 away from the workbench 1. The two ends of the connecting strip 116 are slidably engaged with the annular groove 115 through the rotating shaft 113. The outer wall of the rotating shaft 113 is provided with a first gear 117. The first gear 115 is provided with a first gear 117. The first motor 114 drives the first gear 117 to rotate, and a rack 118 is provided on one side of the annular groove 115 to mesh with the first gear 117. The first motor 114 drives the first gear 117 to rotate, and then drives the first gear 117 to mesh with the rack 118, so that the first gear 117 moves in the annular groove 115, thereby driving the lifting plate 9 to move along the annular groove 115 as a moving track. When the lifting plate 9 is in contact with the side wall of the cardboard, it moves upward, lifts the cardboard stack for a certain distance, and reduces the pressure on the bottom cardboard.

[0037] like Figure 1 - Fig.11 As shown, the first motor 114 is arranged on the side frame 112 away from the connecting strip 116, and the rotating shaft 113 is driven to rotate by the first motor 114. A limiting groove 12 is provided on the inner side of the annular groove 115 on the outer wall of the side frame 112, and one side of the first motor 114 is engaged and slidably connected with the limiting groove 12. By driving the first motor 114, the first gear 117 is driven to rotate, wherein the first motor 114 is limited by the limiting groove 12, which can prevent the first motor 114 from rotating when the first gear 117 drives the first motor 114 to move around the annular groove 115.

[0038] like Figure 1 - Fig.11 As shown, there are two annular grooves 115 on a side frame 112 and they are located at both ends of the side frame 112, and there are two connecting strips 116 and they are arranged corresponding to the upper and lower groups of annular grooves 115. By setting the upper and lower groups of annular grooves 115, the stability of the lifting plate 9 during the lifting process can be effectively guaranteed.

[0039] like Figure 1 - Fig.11 As shown, baffles 102 are symmetrically provided on the workbench 1 located on both sides of the feeding conveyor belt 2 through brackets 101. The lower side of the baffle 102 is in contact with the upper side of the feeding conveyor belt 2, and the inner side is in contact with the side wall of the cardboard. The height of the baffle 102 is adapted to the height of a cardboard. By setting the baffle 102, the lifting plate 9 is prevented from moving the lowest layer of cardboard upward when moving upward, and only the upper cardboard is lifted.

[0040] like Figure 1 - Fig.11As shown, an assembly groove 131 is provided above the push plate 7, and the push airbag 8 is arranged in the assembly groove 131. One side of the push plate 7 is assembled and connected with the workbench 1 through a cylinder 134. A push rod 132 is provided below the lifting plate 9. A fixed tube 133 is sleeved on the outer wall of the lower end of the push rod 132. The other end of the fixed tube 133 is sealed and connected with the push airbag 8. When the lifting plate 9 moves downward, the push rod 132 can be driven to move downward and extend into the fixed tube 133, pushing the original gas in the fixed tube 133 into the push airbag 8, thereby propping up the push airbag 8. The propped-up push airbag 8 lifts the cardboard above to create a gap.

[0041] like Figure 1 - Fig.11 As shown, one end of the fixed tube 133 is connected to the inside of the push airbag 8 through a hose passing through the push plate 7, a mounting plate 141 is provided above the push rod 132, a strip groove 142 is provided above the mounting plate 141, and a telescopic rod 143 is provided below the lifting plate 9 to engage and slide with the strip groove 142. Through the cooperation between the strip groove 142 and the telescopic rod 143, the left and right movement of the lifting plate 9 will not affect the up and down push of the push rod 132 in the fixed tube 133.

[0042] like Figure 1 - Fig.11 As shown, the inner side of the right angle frame 4 at the discharge chute 6 is chamfered. By chamfering the discharge chute 6, it is avoided that the cardboard below is stuck and cannot be discharged when being discharged from the discharge chute 6.

[0043] like Figure 1 - Fig.11 As shown, the outer walls of adjacent right-angle frames 4 are driven and adjusted by a telescopic mechanism, and the telescopic mechanism includes a tooth plate 151, a fixed box 152, a second motor 153 and a second gear 154. The fixed box 152 is assembled and connected to the workbench 1 through a support frame 156 at the bottom. Two tooth plates 151 are provided, and the end faces are respectively assembled and connected to the outer walls of two adjacent right-angle frames 4. The two tooth plates 151 are slidably arranged in the fixed box 152 on opposite sides, and the second gear 154 is rotatably arranged between the fixed boxes 152. The tooth plate 151 is meshed with the second gear 154, and the second gear 154 is driven to rotate by the second motor 153. By driving the second motor 153 to rotate, the second gear 154 is driven to rotate, and then the two tooth plates 151 are driven to move in the opposite direction synchronously, thereby driving the two adjacent right-angle frames 4 to move in the opposite direction synchronously, so as to achieve the situation of adjusting the internal range of the workbench 1.

[0044] like Figure 1 - Fig.11As shown, the telescopic mechanism is provided with four ones which are respectively located between adjacent right-angle frames 4. Among the two telescopic mechanisms arranged opposite to each other, only one second gear 154 is driven to rotate by the second motor 153. By driving the second gear 154 in the telescopic mechanism on one side to rotate by the second motor 153, the driving source can be reduced to a certain extent, while ensuring the normal operation of the workbench 1 driven by the telescopic mechanism.

[0045] Working principle: When loading carton boards, the carton boards are stacked and placed between four right-angle frames 4, wherein the distance between the four right-angle frames 4 can be adjusted according to the length and width of the carton boards. After adjustment, the inner wall of the right-angle frame 4 slides and fits with the edge of the cardboard. Under the action of gravity, the lowest cardboard falls on the loading conveyor belt 2. When loading, the loading conveyor belt 2 is driven to rotate, and the pushing mechanism drives the push plate 7 to push back and forth. The driving mechanism is started to drive the lifting plate 9 to lift and lower back and forth. The lowest cardboard is pushed by the push plate 7 to slide and displace between the upper cardboard and gradually separates from the workbench 1 under the action of the loading conveyor belt 2. The lower cardboard is discharged from the discharge chute 6. When the push plate 7 pushes the lower cardboard and When it extends to the bottom of the second-to-last cardboard, the top-pushing airbag 8 is inflated, so that a certain gap is opened between the bottom and the second cardboard below. At the same time, the driving mechanism drives the lifting plate 9 to move to all cardboard sides except the top of the bottom cardboard and fit tightly. The driving mechanism drives the lifting plate 9 to move upward. The clamping cooperation of the two lifting plates 9 can lift the cardboard pile as a whole for a certain distance. At this time, the pressure of the cardboard stacked above on the cardboard moving out of the bottom can be greatly reduced, so that the friction between the feeding conveyor belt 2 and the bottom cardboard is much greater than the friction between the adjacent cardboards below, so that the cardboard can smoothly follow the feeding conveyor belt 2 to move out of the workbench 1, realizing stable transportation and stable transmission of the cardboard.
