Description

Technical Field

[0001] The present invention relates to a corrugated paper processing device, and more particularly to a corrugated paper feeding and placing device. Background Art

[0002] With the continuous and rapid development of China's national economy, it has driven the rapid development of industries such as home appliances, machinery, electronics, information, and food, thus triggering an increasing demand for carton packaging in various industries and higher requirements for carton packaging printing. Among them, the accuracy and smoothness of paper feeding are of great significance for carton packaging printing.

[0003] In the existing process of corrugated paper placement, a large number of corrugated papers are orderly poured onto the conveying mechanism by workers. At this time, the corrugated papers are in a non-flat state with partial overlap, that is, the corrugated papers are placed one by one on the conveying mechanism; the corrugated papers are conveyed to the feeding and sending platform by the conveying mechanism, and the corrugated papers are vertically stacked on the feeding and sending platform (for example, a leading-edge paper feeding device disclosed in the authorized announcement number CN108859244B), and the placement is completed; then the corrugated papers are sequentially sent out by the sending mechanism, and then the processing begins.

[0004] The existing corrugated paper placement device has the following problems:

[0005] After passing through the conveying mechanism, the corrugated papers fall onto the feeding and sending platform. Since the height of the feeding and sending platform is much lower than the conveying plane height of the conveying mechanism, that is, the height of the blanking channel is relatively large, slightly it will cause the corrugated papers falling onto the feeding and sending platform to have uneven postures and need to be patted straight, seriously it may cause the corrugated papers to stand upright on the feeding and sending platform, affecting the subsequent placement of corrugated papers, and it is necessary to stop the machine to place them properly, which affects the work efficiency. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above problems and provide a corrugated paper feeding and placing device, which can complete the placement of corrugated papers more properly and is beneficial to improving work efficiency.

[0007] The purpose of the present invention is achieved by the following technical solutions:

[0008] A corrugated paper feeding and placing device includes a feeding and conveying mechanism and a feeding and supporting mechanism;

[0009] The feeding and conveying mechanism includes a front-end conveying mechanism and a rear-end conveying mechanism. The front-end conveying mechanism includes a front-end conveyor belt and a front-end conveying driving mechanism. The rear-end conveying mechanism includes conveying rollers and a roller driving mechanism. In the conveying direction, the conveying rollers are located downstream of the front-end conveyor belt;

[0010] The delivery support mechanism includes a support plate and a vertical drive mechanism. The support plates are provided with two and are arranged opposite to each other on the same horizontal plane. The vertical drive mechanism is used to drive the support plate to move vertically above the loading and sending platform.

[0011] The working principle of the above-mentioned corrugated paper feeding device is as follows:

[0012] When working, the support plate is first driven to move to the highest position through the vertical drive mechanism, at which time the height of the blanking channel is the smallest; the corrugated paper to be processed is laid on the front conveyor belt through the automatic discharge mechanism, and the corrugated paper is now stacked one by one on the front conveyor belt; the corrugated paper is transported toward the conveying roller through the front conveyor belt; when the corrugated paper is transported to the conveying roller, the conveying roller pushes the corrugated paper forward to the blanking channel; since the height of the blanking channel is relatively small, the corrugated paper that has just come out can be supported to prevent the corrugated paper from tilting too much, thereby ensuring that the corrugated paper can fall onto the support plate more upright.

[0013] Furthermore, as the corrugated paper is continuously put on the support plate, the vertical drive mechanism gradually drives the support plate down, so that the height of the material drop channel is within the specified range, which is convenient for dropping. When the corrugated paper on the support plate is loaded to a certain amount, the support plate transfers the corrugated paper to the feeding and sending platform; the corrugated paper is sent out in turn by the sending mechanism, and the corrugated paper begins to be processed.

[0014] A preferred embodiment of the present invention, wherein the rear-end conveying mechanism also includes a rear-end conveying belt and a rear-end conveying driving mechanism; the rear-end conveying belt is provided with a shifting tooth for shifting the bottom of the corrugated paper located at the front end; the rear-end conveying belt is located downstream of the front-end conveying belt. Through the above structure, another working mode can be implemented. This mode is suitable for occasions where the height of the blanking channel is relatively large. For example, when the support plate starts to support the corrugated paper, the rear conveyor belt with a shifting tooth pushes the corrugated paper for the final time. The advantages of this are: first, the upper shifting tooth of the rear conveyor belt will push the bottom of the corrugated paper at the front end forward, so that the corrugated paper can continue to be conveyed forward, lengthening the distance the corrugated paper moves forward, pushing the corrugated paper out as far as possible, preventing the corrugated paper from falling down prematurely and head down, which is conducive to ensuring that the corrugated paper falls properly on the support plate; second, by pushing the corrugated paper into the blanking channel one by one through the shifting tooth, the end of the corrugated paper can be pushed to a fixed position, thereby ensuring that the corrugated paper is flush in this direction, so no other alignment mechanism is required for alignment. Furthermore, if the shifting tooth is not needed for auxiliary conveying, the shifting tooth can be transferred to the bottom of the belt, which will not affect the conveying of the corrugated paper, which is very clever.

[0015] Furthermore, at least two rear conveyor belts are provided and are parallel to each other; at least two conveyor rollers are provided and are connected to the same rotating shaft; the rear conveyor belt is located between the conveyor rollers; compared with the conveyor rollers, the end of the rear conveyor belt is closer to the blanking channel.

[0016] Furthermore, the rear conveyor driving mechanism includes a rear conveyor driving motor and a rear conveyor transmission structure.

[0017] A preferred embodiment of the present invention, wherein the front conveyor driving mechanism includes a front conveyor driving motor and a front conveyor transmission structure.

[0018] A preferred embodiment of the present invention, wherein the roller driving mechanism includes a roller driving motor and a roller transmission structure.

[0019] A preferred embodiment of the present invention, wherein two sets of vertical driving mechanisms are provided and each includes a vertical moving seat, a vertical driving motor, and a vertical transmission component; the supporting plate is arranged on the vertical moving seat; the vertical transmission component includes a vertical lead screw and a vertical lead screw nut, and the vertical lead screw nut is fixedly connected to the vertical moving seat. Through the above structure, under the drive of the vertical driving motor, the supporting plate can be driven to lift and lower, so as to more closely receive the corrugated paper.

[0020] Furthermore, the placing and supporting mechanism further includes a downward turning mechanism for driving the supporting plate to turn downward. Two sets of the downward turning mechanisms are provided and each includes a downward turning driving motor and a downward turning transmission component; the downward turning transmission component includes a downward turning worm and a downward turning worm gear, and the axis of the downward turning worm is parallel to the axis of the vertical lead screw; the downward turning worm gear is fixedly connected to the supporting plate; the supporting plate is rotatably connected to the vertical moving seat. Through the above structure, in one working mode, it is necessary to place the supporting plate horizontally in the blanking channel to receive the supporting plate, so as to reduce the drop of the corrugated paper and enable the corrugated paper to be placed more neatly; moreover, when a certain amount of corrugated paper is loaded on the supporting plate, the supporting plate can be driven to turn downward by the downward turning driving motor, so as to transfer the corrugated paper to the upper feeding and sending platform below. In another working mode, when the supporting plate is not required to receive the corrugated paper, the supporting plate can be switched to a vertical posture and hidden on the side, so as not to affect the placement of the corrugated paper.

[0021] Furthermore, the downward turning driving motor is constituted by the vertical driving motor, and the vertical driving motor is arranged on the side plate of the blanking channel; both the vertical lead screw and the downward turning worm are rotatably connected to the side plate;

[0022] The downward turning mechanism further includes a power switching structure, which includes a power electromagnet, a transmission gear structure, and a switching block; the power electromagnet is fixedly arranged on the side plate of the blanking channel; the transmission gear structure includes a driving gear and a driven gear, the driving gear is arranged on the output shaft of the vertical driving motor through a movable transmission structure, the movable transmission structure includes a keyway, a circumferential limiting key, and a sliding groove, the keyway is opened on the output shaft of the vertical driving motor, the sliding groove is opened on the driving gear, one side of the circumferential limiting key is fixedly arranged in the keyway, and the other side of the circumferential limiting key extends into the sliding groove movably; there are two driven gears which are respectively arranged on the vertical lead screw and the downward turning worm, and the two driven gears are at different heights; one end of the switching block is fixedly connected with the telescopic rod of the power electromagnet, and the other end of the switching block is provided with a slot; a part of the driving gear is fitted in the slot.

[0023] With the above structure, sharing one driving motor can simplify the structure and reduce the cost. When the vertical driving support plate is needed, the power electromagnet drives the switching block to move vertically in the corresponding direction, and the switching block drives the driving gear to mesh with the driven gear corresponding to the vertical lead screw, so as to realize the vertical power transmission, and then the support plate can be driven to move vertically. When the support plate needs to be turned downward, according to the above operation, the power electromagnet drives the switching block to move vertically in the corresponding direction, and the driving wheel is switched to mesh with the driven gear corresponding to the downward turning worm, so as to realize the downward turning power transmission, and then the support plate can be driven to turn downward.

[0024] Furthermore, a vertical guiding structure is arranged between the vertical moving seat and the side plate, and the vertical guiding structure includes a vertical guide rod and a vertical guide sleeve, the vertical guide rod is vertically and fixedly connected to the side plate, and the vertical guide sleeve is fixedly arranged on the vertical moving seat.

[0025] In a preferred embodiment of the present invention, it further includes a feeding and aligning mechanism, which includes an aligning plate and an aligning driving cylinder, the aligning driving cylinder is fixedly arranged on the frame, and the aligning plate is connected with the telescopic rod of the aligning driving cylinder. Through the above structure, the corrugated paper dropped can be aligned uniformly, and finally the posture of the corrugated paper can be ensured to be correct.

[0026] The present invention has the following beneficial effects compared with the prior art:

[0027] The corrugated paper feeding and dropping device of the present invention drives the support plate to move to the highest position through the vertical driving mechanism, and tries to reduce the height of the blanking channel as much as possible, so that the just-out corrugated paper can be supported, preventing the corrugated paper from tilting too much, and ensuring that the corrugated paper can fall onto the support plate relatively correctly.

[0035] In order to enable those skilled in the art to well understand the technical solution of the present invention, the present invention will be further described below in conjunction with embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0036] Refer to Figures 1-4 , the corrugated paper feeding and placing device of this embodiment includes a placing and conveying mechanism, a placing and supporting mechanism, and a placing and straightening mechanism; the placing and conveying mechanism includes a front-end conveying mechanism and a rear-end conveying mechanism, the front-end conveying mechanism includes a front-end conveyor belt 1 and a front-end conveying driving mechanism, the rear-end conveying mechanism includes conveying rollers 2 and a roller driving mechanism, and in the conveying direction, the conveying rollers 2 are located downstream of the front-end conveyor belt 1.

[0037] Among them, the front-end conveying driving mechanism includes a front-end conveying driving motor (not shown in the figure) and a front-end conveying transmission structure; specifically, the front-end conveying transmission structure can refer to the prior art. The roller driving mechanism includes a roller driving motor 3 and a roller transmission structure; specifically, the roller transmission structure can refer to the prior art.

[0038] Refer to Figures 1-4, the rear-end conveying mechanism further includes a rear-end conveyor belt 4 and a rear-end conveying drive mechanism; the rear-end conveyor belt 4 is provided with teeth 4-1 for pushing the bottom of the corrugated paper at the forefront; the rear-end conveyor belt 4 is located downstream of the front-end conveyor belt 1. With the above structure, another working mode can be carried out, which is suitable for occasions where the height of the blanking channel is relatively large. For example, when the supporting plate just starts to support the corrugated paper, the rear-end conveyor belt with teeth is used to push the corrugated paper for the last time. The advantages are as follows: First, the teeth on the rear-end conveyor belt will push forward the bottom of the corrugated paper at the forefront, so that the corrugated paper can continue to be conveyed forward, lengthening the moving distance of the corrugated paper forward and pushing the corrugated paper out as far as possible to prevent the corrugated paper from falling down prematurely and head-down, which is beneficial to ensuring that the corrugated paper falls correctly onto the supporting plate; Second, by pushing and sending the corrugated paper into the blanking channel one by one with the teeth, the end of the corrugated paper can be pushed to a fixed position, so as to ensure that the corrugated paper is flush in this direction. Therefore, no other straightening mechanism is required for straightening. Further, when the teeth are not needed for auxiliary conveying, the teeth can be moved under the belt, which will not affect the conveying of the corrugated paper, which is very ingenious.

[0039] Further, at least two rear-end conveyor belts 4 are provided and are parallel to each other; at least two conveying rollers 2 are provided and are connected to the same rotating shaft; the rear-end conveyor belt 4 is located between the conveying rollers 2; compared with the conveying rollers 2, the end of the rear-end conveyor belt 4 is closer to the blanking channel.

[0040] Further, the rear-end conveying drive mechanism includes a rear-end conveying drive motor 5 and a rear-end conveying transmission structure; specifically, the rear-end conveying transmission structure can refer to the prior art.

[0041] See Figures 5-7 , the placing and supporting mechanism includes a supporting plate 6 and a vertical drive mechanism. Two supporting plates 6 are provided and are oppositely arranged on the same horizontal plane. The vertical drive mechanism is used to drive the supporting plate 6 to move vertically above the feeding and sending platform 7. Among them, two groups of vertical drive mechanisms are provided and each includes a vertical moving seat 8, a vertical drive motor 9 and a vertical transmission component; the supporting plate 6 is arranged on the vertical moving seat 8; the vertical transmission component includes a vertical lead screw 10 and a vertical lead screw nut, and the vertical lead screw nut is fixedly connected to the vertical moving seat 8. With the above structure, under the drive of the vertical drive motor 9, the supporting plate 6 can be driven to lift and lower, so as to receive the corrugated paper more closely.

[0042] Furthermore, the feeding support mechanism further includes a downward turning mechanism for driving the support plate 6 to turn downward. There are two sets of the downward turning mechanisms, and each includes a downward turning driving motor and a downward turning transmission assembly. The downward turning transmission assembly includes a downward turning worm 11 and a downward turning worm wheel 12. The axis of the downward turning worm 11 is parallel to the axis of the vertical lead screw 10. The downward turning worm wheel 12 is fixedly connected to the support plate 6. The support plate 6 is rotatably connected to the vertical moving seat 8. With the above structure, in one working mode, it is necessary to horizontally place the support plate in the blanking channel to support the support plate, so as to reduce the drop of the corrugated paper and enable the corrugated paper to be placed more neatly. Moreover, when a certain amount of corrugated paper is loaded on the support plate, the support plate can be driven to turn downward by the downward turning driving motor, and the corrugated paper can be transferred to the upper feeding and sending platform below. In another working mode, when the support plate is not required to support the corrugated paper, the support plate can be switched to a vertical posture and hidden on the side, so as not to affect the feeding of the corrugated paper.

[0043] Furthermore, the downward turning driving motor is constituted by the vertical driving motor 9, and the vertical driving motor 9 is arranged on the side plate 13 of the blanking channel. The vertical lead screw 10 and the downward turning worm 11 are both rotatably connected to the side plate 13. The downward turning mechanism further includes a power switching structure, which includes a power electromagnet 14, a transmission gear structure and a switching block 15. The power electromagnet 14 is fixedly arranged on the side plate 13 of the blanking channel. The transmission gear structure includes a driving gear 16 and a driven gear 17. The driving gear 16 is arranged on the output shaft of the vertical driving motor 9 through a movable transmission structure. The movable transmission structure includes a keyway, a circumferential limiting key 18 and a sliding groove. The keyway is opened on the output shaft of the vertical driving motor 9, the sliding groove is opened on the driving gear 16, one side of the circumferential limiting key 18 is fixedly arranged in the keyway, and the other side of the circumferential limiting key 18 extends into the sliding groove movably. There are two driven gears 17, which are respectively arranged on the vertical lead screw 10 and the downward turning worm 11, and the two driven gears 17 are at different heights. One end of the switching block 15 is fixedly connected to the telescopic rod of the power electromagnet 14, and the other end of the switching block 15 is provided with a dial groove. A part of the driving gear 16 is fitted in the dial groove.

[0044] With the above structure, sharing a driving motor can simplify the structure and reduce costs. When the vertical driving support plate 6 needs to be driven, the power electromagnet 14 drives the switching block 15 to move vertically in the corresponding direction, and the switching block 15 drives the driving gear 16 to mesh with the driven gear 17 corresponding to the vertical lead screw 10, so as to realize the vertical power transmission, and then the support plate 6 can be driven to move vertically. When the support plate 6 needs to be turned down, according to the above operation, the power electromagnet 14 drives the switching block 15 to move vertically in the corresponding direction, and the driving wheel is switched to mesh with the driven gear 17 corresponding to the down-turning worm 11, so as to realize the down-turning power transmission, and then the support plate 6 can be driven to turn down.

[0045] Further, a vertical guiding structure is provided between the vertical moving seat 8 and the side plate 13. The vertical guiding structure includes a vertical guide rod 19 and a vertical guide sleeve 20. The vertical guide rod 19 is vertically fixedly connected to the side plate 13, and the vertical guide sleeve 20 is fixedly arranged on the vertical moving seat 8.

[0046] See Figure 3 , the feeding and aligning mechanism includes an aligning plate 21 and an aligning driving cylinder 22. The aligning driving cylinder 22 is fixedly arranged on the rack, and the aligning plate 21 is connected to the telescopic rod of the aligning driving cylinder 22. With the above structure, the corrugated paper dropped can be aligned uniformly, and finally the posture of the corrugated paper can be ensured to be correct.

[0047] See Figures 1-5 , the working principle of the corrugated paper feeding and dropping device in this embodiment is as follows:

[0048] During operation, first drive the support plate 6 to move to the highest position through the vertical driving mechanism. At this time, the height of the blanking channel is the smallest; the corrugated paper to be processed is laid on the front conveyor belt 1 through the automatic feeding mechanism. At this time, the corrugated paper is in a non-flat state with partial overlap, that is, the corrugated papers are stacked one by one on the front conveyor belt 1; the corrugated paper is conveyed towards the conveying roller 2 through the front conveyor belt 1; when the corrugated paper is conveyed onto the conveying roller 2, the conveying roller 2 then pushes the corrugated paper forward towards the blanking channel; due to the small height of the blanking channel, the just-out corrugated paper can be supported, preventing the corrugated paper from tilting too much, and ensuring that the corrugated paper can fall onto the support plate 6 relatively correctly.

[0049] Further, as the corrugated paper is continuously dropped onto the support plate 6, the vertical driving mechanism gradually drives the support plate 6 to descend, so that the height of the blanking channel is within a specified range for convenient dropping. When a certain amount of corrugated paper is loaded on the support plate 6, the support plate 6 transfers the corrugated paper to the feeding and sending platform 7; the corrugated paper is sent out in sequence through the sending mechanism, and the processing of the corrugated paper begins.

[0050] The above is a preferred embodiment of the present invention. However, the embodiments of the present invention are not limited to the above content.
