Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper feeding, and specifically relates to an automatic corrugated board feeding device. Background Art

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper with a waveform formed by processing through a corrugating roll. Corrugated paper has good compressive, impact and tear resistance strengths, and can protect the packaged goods from damage.

[0003] The existing patent with the publication number CN113060533B in China discloses a feeding device for corrugated board blanks, but the above patent still has the following defects:

[0004] First, several cardboard sheets are stacked between two limiting plates. After the lifting rod rises, the cardboard sheets stacked between the two limiting plates will correspond to the pushing plate. Thereafter, the pushing plate will push the cardboard sheets towards the conveying device. However, in actual operation, the downstream processing procedures need to process single cardboard sheets in sequence. When the pushing plate in the above patent is pushed out, the stacked cardboard sheets will be pushed towards the conveying device together, and single cardboard sheet feeding cannot be achieved.

[0005] Second, when transporting single cardboard sheets, a dialing plate device is required. The traditional dialing plate device usually uses the cooperation of a conveyor belt and a limiting plate to achieve the single cardboard sheet transportation. In actual operation, the conveyor belt rotates continuously. The conveyor belt is used to drive the bottom cardboard sheet forward. When the bottom cardboard sheet is translated, the limiting plate is used to prevent the upper cardboard sheets from being driven forward by the lower cardboard sheet due to friction. However, in the traditional dialing plate device, since the conveyor belt rotates continuously, when the bottom cardboard sheet starts to be transported, the cardboard sheets located above will contact the conveyor belt, and thus the cardboard sheets above will be continuously pressed against the limiting plate by the conveyor belt, and finally the cardboard sheets above will have end bending or edge warping.

[0006] Third, since the cardboard sheets will have edge warping during the transfer process, when the bottom cardboard sheet is driven forward by the conveyor belt, the bottom cardboard sheet will pass through below the limiting plate. However, if the bottom cardboard sheet has edge warping, then the bottom cardboard sheet will be stuck by the limiting plate due to the edge warping and cannot drive out.

DETAILED DESCRIPTION

[0044] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] refer to Figures 1 to 20 The automatic corrugated cardboard feeding device shown in the figure comprises a support frame 1 and a feeding platform 2 arranged on the support frame 1, a through hole 3 is arranged on the feeding platform 2, a lifting platform 4 is arranged directly below the through hole 3, a support plate 5 and a pushing mechanism are arranged on the lifting platform 4, the support plate 5 is horizontally mounted on the lifting platform 4, the pushing mechanism is arranged below the support plate 5, the pushing mechanism comprises a strip mounting platform 6, a translation rod 7, a translation driving member and two symmetrical one-way rubber wheels 8, the strip mounting platform 6 is arranged on the lifting platform 4 (as shown in FIG. Figure 6 As shown), translation rod 7 (as Figure 8 As shown) slides horizontally at the bottom of the support plate 5, each one-way rubber wheel 8 (as shown Fig.12The support plate 5 is provided with a notch 9 corresponding to the two one-way rubber wheels 8 at one end of the support plate 5. The top of the feeding platform 2 is provided with a roller conveyor, a limit frame, a gravity pressing member and a blocking member. The limit frame and the roller conveyor are sequentially distributed on the sides of the through-port 3 along the conveying direction of the cardboard. The roller conveyor includes two rollers 10 distributed up and down. The gravity pressing member includes a pressing plate 11 slidably connected to the feeding platform 2 in a vertical direction. The pressing plate 11 corresponds to the through-port 3. The blocking member includes a plurality of limit strips 12 vertically arranged on the sides of the roller conveyor.

[0046] The device is used to feed a plurality of stacked cardboards one by one. The specific feeding process is as follows: the lifting platform 4 is started to descend. After the lifting platform 4 descends a certain distance, the lifting platform 4 stops descending. Thereafter, a forklift is used to place the stacked cardboards on the support plate 5 on the lifting platform 4. After the cardboards are placed on the support plate 5, the lifting platform 4 starts to rise. During this process, the top cardboard on the support plate 5 will upwardly collide with the pressing plate 11. Thereafter, as the lifting platform 4 continues to rise, the pressing plate 11 will press on the top cardboard and the pressing plate 11 will rise together with the lifting platform 4. At the same time, the stacked cards The board will pass through the limit frame upwards. When the lifting platform 4 rises until the support plate 5 is exposed from the opening 3, the lifting platform 4 stops rising. At this time, the bottom layer of paperboard on the support plate 5 will correspond to the roller conveyor. Thereafter, the translation drive member is started, and the translation drive member drives the translation rod 7 to translate toward the roller conveyor. During this process, the two one-way rubber wheels 8 will fit the bottom layer of paperboard through the notch 9. At this time, the one-way rubber wheels 8 will not rotate. Therefore, through the movement of the two one-way rubber wheels 8, the bottom layer of paperboard will be driven to translate toward between the two rollers 10. In the process of the bottom layer of paperboard extending toward the roller 10, the function of a plurality of limit strips 12 is to prevent The upper cardboard is driven by the bottom cardboard due to friction and extends outward together. When one end of the cardboard passes between the two rollers 10, the translation drive component drives the translation rod 7 to slide in the opposite direction. During this process, each one-way rubber wheel 8 will roll in contact with the bottom cardboard. Since the one-way rubber wheel 8 will roll during the reverse translation, the one-way rubber wheel 8 will not drive the cardboard to move in the opposite direction. Thereafter, as the rollers 10 rotate, the cardboard will be driven by the two rollers 10 to continue to translate forward. Finally, the bottom cardboard will be transported forward from the pallet 5. When the bottom cardboard leaves the pallet 5, the cardboard on the upper side will drop due to gravity and turn To form the bottom layer of cardboard, the translation rod 7 will then translate toward the roller 10 again, and the bottom layer of cardboard will be driven by the one-way rubber wheel 8 to translate toward the roller 10 again. In summary, with the reciprocating translation of the two one-way rubber wheels 8, the cardboards stacked on the support plate 5 will be fed one by one from bottom to top in sequence, wherein, during the feeding process of the spirally placed cardboards, the pressing plate 11 will press on the top layer of cardboard, and the action of the pressing plate 11 ensures that the bottom layer of cardboard can be smoothly driven by the one-way rubber wheel 8 to translate toward the roller 10, and during the translation process of the bottom layer of cardboard toward the roller 10, the action of the limit frame prevents the bottom layer of cardboard from deflecting left and right.

[0047] In order to show the specific installation method of the lifting platform 4 and the support plate 5, the following features are set:

[0048] A support platform 13 is fixedly provided below the feeding platform 2, and a vertical plate 14 (such as Figure 6 As shown in FIG. 1 , the lifting platform 4 is slidably connected to the vertical plate 14 in the vertical direction, and four No. 1 support rods 15 (as shown in FIG. 1 ) arranged in a matrix are fixed on the top of the supporting platform 13. Fig.12As shown in the figure), each No. 1 support rod 15 is vertical, and the support plate 5 is fixed to the top of the four No. 1 support rods 15.

[0049] During actual use, the lifting platform 4 can be lifted and lowered by means of a lifting cylinder, an electric slide rail or a transmission chain. Since the lifting method of the lifting platform 4 is the existing technology, the specific structure is not shown in the figure. The support plate 5 is spaced apart from the lifting platform 4 by four No. 1 support rods 15, so that the pushing mechanism can be installed through the gap between the support plate 5 and the lifting platform 4.

[0050] In order to show how the translation rod 7 is slidably connected to the support plate 5, the following features are set:

[0051] The bottom of the support plate 5 is provided with two symmetrical fixing rods 16 (such as Fig.15 As shown in the figure, both ends of each fixed rod 16 are provided with a vertical support 17 fixedly connected to the bottom of the pallet 5, the axial direction of each fixed rod 16 is parallel to the transportation direction of the cardboard, the translation rod 7 is arranged between the two fixed rods 16, and the translation rod 7 is perpendicular to the fixed rod 16, and both ends of the translation rod 7 are fixed with a sliding sleeve 18 sleeved on the fixed rod 16, and each fixed rod 16 is sleeved with a No. 1 spring 19, and the two ends of the No. 1 spring 19 are respectively in conflict with the sliding sleeve 18 and the corresponding vertical support 17.

[0052] The translation rod 7 slides between the two fixed rods 16 through the sliding sleeves 18 at both ends. When the translation drive drives the translation rod 7 to translate toward the roller 10, the sliding sleeve 18 arranged at the end of the translation rod 7 will compress the corresponding spring No. 19, so that the spring No. 19 generates elastic force, and then the translation rod 7 will slide in the opposite direction due to the elastic force of the spring No. 19.

[0053] In order to show the specific structure of the one-way rubber wheel 8, the following features are set:

[0054] Two one-way rubber wheels 8 are respectively arranged at the two ends of the translation rod 7, each of which includes a one-way limiting member and a rubber wheel 20, and the rubber wheel 20 includes an annular frame 21 and a rubber ring 22 (such as Figure 8 As shown), the annular frame 21 is sleeved on the translation rod 7, and the annular frame 21 is rotatably connected to the translation rod 7, the rubber ring 22 is coaxially sleeved outside the annular frame 21, and the one-way limiter includes a fixed toothed disc 23 and a plurality of elastic pawls 24, and the fixed toothed disc 23 is coaxially fixed on the translation rod 7 (as shown Fig.16 As shown), the fixed toothed disc 23 is located beside the annular frame 21, and a circle of ratchet teeth 25 (as shown) is formed on the outer edge of the fixed toothed disc 23. Fig. 20 As shown, a fixing ring 26 is coaxially provided on one side of the annular skeleton 21 facing the fixed toothed disc 23 , and a plurality of elastic pawls 24 are evenly distributed along the circumferential direction of the fixing ring 26 , and each elastic pawl 24 is meshed with a ratchet tooth 25 .

[0055] When the stacked cardboards are placed on the support plate 5, the rubber ring 22 on each rubber wheel 20 will contact the bottom cardboard upwards. When the translation rod 7 slides toward the roller 10, the rubber wheel 20 will have a tendency to rotate due to the contact with the bottom cardboard. However, at this time, the annular frame 21 will be restricted from rotating by the cooperation of the elastic pawl 24 and the ratchet 25. Then the rubber wheel 20 will move the bottom cardboard through the rubber ring 22, and finally the bottom cardboard will be moved toward the roller 10 by the rubber wheel 20. When the translation rod 7 slides in the opposite direction, each elastic pawl 24 will slide on the ratchet 25, so that the annular frame 21 is no longer restricted. Then the entire rubber wheel 20 will roll on the bottom cardboard when the translation rod 7 slides in the opposite direction, and finally the bottom cardboard is prevented from being moved in the opposite direction by the rubber wheel 20 by rolling.

[0056] In order to show the specific structure of the translation drive, the following features are set:

[0057] The translation drive member includes two rotating rods 27 and two cams 28. Fig.13 As shown in the figure, the two rotating rods 27 are arranged between the two rubber wheels 20, and the two rotating rods 27 are spaced apart along the axial direction of the translation rod 7. One end of each rotating rod 27 is hinged to the strip mounting platform 6, and the other end of each rotating rod 27 is provided with a strip through groove 29, and the strip through groove 29 is parallel to the rotating rod 27. The translation rod 7 passes through the two strip through grooves 29. A roller 30 (as shown in the figure) is rotatably arranged on the lower end of each rotating rod 27. Figure 8 As shown), a first rotating shaft 31 is rotatably provided on the strip-shaped mounting platform 6, and the first rotating shaft 31 (as shown Fig.16 As shown in the figure, the axes of the cam 28 and the roller 30 are parallel to the axis of the translation rod 7, the small head end of each cam 28 is coaxially fixed to the first rotating shaft 31, and the small head end of each cam 28 is in conflict with the corresponding roller 30.

[0058] In the initial state, the first spring 19 releases its elastic force to drive the sliding sleeve 18 to contact the corresponding vertical support 17. At this time, the translation rod 7 passing through the strip-shaped through slot 29 will synchronously drive the two rotating rods 27 to maintain a vertical state (such as Figure 8 As shown), when the rotating rod 27 is in a vertical state, the small end of each cam 28 conflicts with the corresponding roller 30. When the bottom paperboard needs to be driven to translate, the first rotating shaft 31 is controlled to rotate clockwise (as shown in FIG. Figure 8As shown in the figure, the two cams 28 will be synchronously driven to rotate clockwise. During this process, the large head end of each cam 28 will turn to the corresponding roller 30, so that through the resistance of the large head end of the cam 28, the roller 30 will drive the corresponding rotating rod 27 to rotate. When the rotating rod 27 rotates, the translation rod 7 will be driven by the two rotating rods 27 to slide toward the roller 10. When the translation rod 7 slides, the sliding sleeve 18 provided on the end of the translation rod 7 will compress the No. 1 spring 19, so that the No. 1 spring 19 generates an elastic force. Thereafter, as the No. 1 rotating shaft 31 continues to rotate, the small head end on the cam 28 will gradually turn to the roller 30. At this time, the translation rod 7 will be driven by the elastic force of the No. 1 spring 19 to slide in the opposite direction. In summary, the reciprocating sliding of the translation rod 7 can be achieved by controlling the No. 1 rotating shaft 31 to rotate continuously, and finally the two rubber wheels 20 are driven to reciprocate through the translation rod 7.

[0059] In order to show the specific installation method of the two rollers 10, the following features are set:

[0060] Two strip seats 32 (such as Figure 2 As shown in the figure, two strip seats 32 are symmetrically arranged on both sides of the through opening 3, two rollers 10 are parallel, and each roller 10 is horizontally arranged between the two strip seats 32, each strip seat 32 is provided with a vertical strip slide 33, a fixed block 34 is fixed at the lower end of the strip slide 33, a slider 35 is slidably arranged at the upper end of the strip slide 33, the two ends of the roller 10 located at the bottom are respectively connected to the two fixed blocks 34 for rotation, and the two ends of the roller 10 located at the top are respectively connected to the two sliders 35 for rotation, a horizontal baffle 36 is fixed on the top of each strip seat 32, a vertical No. 2 spring 37 is arranged at the upper end of the strip slide 33, and the two ends of the No. 2 spring 37 are respectively in conflict with the baffle 36 and the slider 35, and a motor 38 is fixed on the top of the feeding platform 2 (as shown in the figure). Fig. 9 As shown), the output end of the motor 38 is coaxially fixedly connected to the rotating roller 10 located below.

[0061] Each slider 35 is driven to slide downward by the corresponding No. 2 spring 37, so that the upper roller 10 will be pressed toward the lower roller 10 by the drive of the two sliders 35. When the motor 38 is started, the motor 38 will drive the lower roller 10 to rotate. Then, when the bottom cardboard on the support plate 5 extends toward the two rollers 10, the bottom cardboard is rolled between the two rollers 10 by the rotation of the lower roller 10. In this process, the upper roller 10 will be slightly lifted by the elastic force of the two No. 2 springs 37, so that the bottom cardboard can pass through between the two rollers 10. In actual use, a blanking platform 62 (such as Figure 6A conveyor belt (not shown in the figure) is provided beside the blanking platform 62 for conveying the cardboard to the next process.

[0062] In order to show how the first rotating shaft 31 rotates, the following features are set:

[0064] When the motor 38 is started, the motor 38 will drive the rotating roller 10 located below to rotate. At this time, the rotating roller 10 located below will drive the No. 3 bevel gear 48 to rotate through the No. 4 bevel gear 49. When the No. 3 bevel gear 48 rotates, the No. 3 bevel gear 48 will drive the spline shaft 47 to rotate. When the spline shaft 47 rotates, the spline shaft 47 will drive the No. 1 bevel gear 44 to rotate through the No. 2 bevel gear 46. Thereafter, the No. 1 bevel gear 44 will drive the No. 2 synchronous wheel 42 to rotate through the No. 2 rotating shaft 41. Finally, the No. 2 synchronous wheel 42 will drive the No. 1 synchronous wheel 39 to rotate through the synchronous belt 43. When the No. 1 synchronous wheel 39 rotates, the No. 1 rotating shaft 31 will synchronously drive the two cams 28 to rotate.

[0065] In order to ensure that the cardboard placed on the pallet 5 is in a straight position, the following features are set:

[0066] Vertical side panels 50 are provided on both sides of the support plate 5. The lower end of each side panel 50 is provided with a plurality of No. 2 support rods 51 connected to the support platform 13. The end of each side panel 50 facing the vertical panel 14 is formed with a No. 1 baffle 52 perpendicular to the side panel 50.

[0067] When the stacked cardboards are placed on the pallet 5 by a forklift, the two side plates 50 are used to prevent the stacked cardboards from being skewed. At the same time, the two No. 1 blocking bars 52 are used to limit the pushing stroke of the cardboards on the pallet 5, ultimately ensuring that the end of each cardboard is flush with the end of the pallet 5.

[0068] In order to show the specific structures of the limiting frame and the limiting strip 12, the following features are provided:

[0069] The limiting frame includes two groups of corner limiting members in a symmetric state. Each group of corner limiting members includes a second stop bar 53 and a third stop bar 54 that are perpendicularly connected to each other (as Figure 3 shown), and both the second stop bar 53 and the third stop bar 54 are vertical. The two third stop bars 54 are respectively located on both sides of the through port 3. Each third stop bar 54 is fixedly connected to the material conveying platform 2. A fourth stop bar 55 is formed at the lower end of each third stop bar 54 (as Figure 6 shown), and the fourth stop bar 55 is perpendicular to the third stop bar 54. A gantry 56 is fixedly provided at the top of the material conveying platform 2. A number of limiting strips 12 are fixedly connected to the gantry 56 in the horizontal direction, and a warping block 57 that inclines towards the roller 10 is formed at the lower end of each limiting strip 12.

[0070] When the lifting platform 4 ascends, the cardboard stacked on the pallet 5 will upwardly pass through the two groups of corner limiting members. During this process, the two end corners of each cardboard will be respectively restricted by the second stop bar 53 and the third stop bar 54. The two third stop bars 54 are used to prevent the cardboard from shifting left and right. The two second stop bars 53 are used to prevent the bottom cardboard from being driven backward by the reversely sliding rubber wheel 20. The two fourth stop bars 55 are used to prevent the bottom cardboard from shifting left and right during the forward transportation process. When the lifting platform 4 ascends to a stop, the distance between each warping block 57 and the pallet 5 is the same as the thickness of a single cardboard. When the bottom cardboard extends towards the two rollers 10, one end of the bottom cardboard will gradually approach the warping block 57 at the lower end of each limiting strip 12. At this time, the limiting strip 12 and the warping block 57 are used to prevent the upper cardboard from being driven forward by the lower cardboard due to friction, while the bottom cardboard will directly slide under the warping block 57 and finally extend between the two rollers 10.

[0071] In order to show how the pressing plate 11 is slidably connected to the material conveying platform 2, the following features are provided:

[0072] Four vertical rods 58 are fixedly provided at the top of the material conveying platform 2 and are respectively arranged in a matrix beside the through port 3 (as Figure 2 shown). The pressing plate 11 is horizontal, and four guide sleeves 59 are fixedly provided at the top of the pressing plate 11. Each guide sleeve 59 is sleeved on the corresponding vertical rod 58. A limiting ring 60 is formed on each vertical rod 58. A number of guide pulleys 61 are rotatably provided at the bottom of the pressing plate 11 and are equidistantly distributed along the conveying direction of the cardboard.

[0073] In the initial state, the pressing plate 11 is in a descending state due to gravity. At this time, each guide sleeve 59 will conflict with the limit ring 60 downward, and the limit ring 60 will limit the downward stroke of the guide sleeve 59, and finally ensure that the pressing plate 11 will hover above the lifting platform 4. When the lifting platform 4 drives the cardboard on the pallet 5 to rise, the cardboard stacked on the pallet 5 will gradually approach the pressing plate 11 upward, and then the top cardboard will be pressed upward on the several guide pulleys 61 at the bottom of the pressing plate 11. Finally, the pressing plate 11 will be driven up by the stacked cardboard until the lifting platform 4 stops moving. Then, when the number of cardboards on the pallet 5 gradually decreases, the pressure of the pressing plate 11 is used to ensure that the bottom cardboard can be smoothly pushed to the roller 10 by the rubber wheel 20, and the several guide pulleys 61 provided at the bottom of the pressing plate 11 are used to guide the transportation of the bottom cardboard.

[0074] Working principle:

[0075] The device is used to feed a plurality of stacked cardboards one by one. The specific feeding process is as follows: the lifting platform 4 is started to descend. After the lifting platform 4 descends a certain distance, the lifting platform 4 stops descending. Thereafter, a forklift is used to place the stacked cardboards on the support plate 5 on the lifting platform 4. After the cardboards are placed on the support plate 5, the lifting platform 4 starts to rise. During this process, the top cardboard on the support plate 5 will upwardly collide with the pressing plate 11. Thereafter, as the lifting platform 4 continues to rise, the pressing plate 11 will press on the top cardboard and the pressing plate 11 will rise together with the lifting platform 4. At the same time, the stacked cards The board will pass through the limit frame upwards. When the lifting platform 4 rises until the support plate 5 is exposed from the opening 3, the lifting platform 4 stops rising. At this time, the bottom layer of paperboard on the support plate 5 will correspond to the roller conveyor. Thereafter, the translation drive member is started, and the translation drive member drives the translation rod 7 to translate toward the roller conveyor. During this process, the two one-way rubber wheels 8 will fit the bottom layer of paperboard through the notch 9. At this time, the one-way rubber wheels 8 will not rotate. Therefore, through the movement of the two one-way rubber wheels 8, the bottom layer of paperboard will be driven to translate toward between the two rollers 10. In the process of the bottom layer of paperboard extending toward the roller 10, the function of a plurality of limit strips 12 is to prevent The upper cardboard is driven by the bottom cardboard due to friction and extends outward together. When one end of the cardboard passes between the two rollers 10, the translation drive component drives the translation rod 7 to slide in the opposite direction. During this process, each one-way rubber wheel 8 will roll in contact with the bottom cardboard. Since the one-way rubber wheel 8 will roll during the reverse translation, the one-way rubber wheel 8 will not drive the cardboard to move in the opposite direction. Thereafter, as the rollers 10 rotate, the cardboard will be driven by the two rollers 10 to continue to translate forward. Finally, the bottom cardboard will be transported forward from the pallet 5. When the bottom cardboard leaves the pallet 5, the cardboard on the upper side will drop due to gravity and turn To form the bottom layer of cardboard, the translation rod 7 will then translate toward the roller 10 again, and the bottom layer of cardboard will be driven by the one-way rubber wheel 8 to translate toward the roller 10 again. In summary, with the reciprocating translation of the two one-way rubber wheels 8, the cardboards stacked on the support plate 5 will be fed one by one from bottom to top in sequence, wherein, during the feeding process of the spirally placed cardboards, the pressing plate 11 will press on the top layer of cardboard, and the action of the pressing plate 11 ensures that the bottom layer of cardboard can be smoothly driven by the one-way rubber wheel 8 to translate toward the roller 10, and during the translation process of the bottom layer of cardboard toward the roller 10, the action of the limit frame prevents the bottom layer of cardboard from deflecting left and right.
