Description

Technical Field

[0001] The present invention relates to the technical field of carton printing machines, and in particular to a fully automatic loading carton printing machine and a use method thereof. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the papers produced by different manufacturers are also different. In the process of using existing carton printing machines, the problem of inconvenient loading often occurs. Workers need to manually take the cardboards to the loading frame one by one to realize printing and loading. However, this loading method is inefficient and costly, and can no longer meet the existing market demand.

[0003] In the prior art, a patent application numbered CN201720011409.2 discloses a fully automatic loading carton printing machine, which adjusts the height of a movable cardboard loading platform according to a distance signal sent back by a laser sensor, so that the top cardboard of the movable cardboard loading platform contacts the lower surface of the feeding conveyor belt, and then starts the feeding conveyor belt to transport the top cardboard to the loading frame, and then lifts the movable cardboard loading platform by the thickness of one cardboard again to prepare for the loading of the next cardboard; however, there are still defects in the specific use process, because the laser sensor is a precision electronic sensing device, which is prone to error, and then the loading platform is prone to fail to adjust the height in time, resulting in intermittent loading; and after a stack of cardboards is delivered, the movable cardboard loading platform needs to be controlled to move down to the lowest height before another stack of cardboards to be processed can be placed again, and the waiting time for placing the cardboards is long, which reduces the efficiency of cardboard processing.

[0019] The present invention also discloses a method for using a fully automatic loading carton printing machine, comprising the following steps:

[0020] S1: When the device is initially working, the sleeve of the second lifting assembly drives the support plate to be placed on the upper side of the loading box, and the support plate of the second lifting assembly is pulled up by the winding assembly, the sleeve of the first lifting assembly drives the support plate to be placed on the lower side of the loading box, and the support plate of the first lifting assembly is not pulled up by the winding assembly, and then a stack of paperboards to be processed and printed is placed on the support plate of the first lifting assembly, and the stacked paperboards are placed between the two auxiliary side plates;

[0021] S2: Control the driving motor and the lifting motor to work. When the driving motor is working, the driving shaft drives the rubber paddle to rotate on the upper side of the loading box. When the lifting motor is working, the screw of the first lifting assembly is driven to rotate vertically in the loading box.

[0022] When the driving shaft rotates, the input shaft of the belt conveyor is driven to rotate through the second synchronous wheel and the second synchronous belt, thereby making the belt conveyor perform transmission work through the belt;

[0023] S3: As the screw rotates, the sleeve of the first lifting assembly drives the cardboard to move upward through the support plate, and the sleeve of the second lifting assembly drives the support plate to move downward;

[0024] S4: After the first lifting assembly works, the cardboard on the first layer moves to be flush with the discharge slot. As the rubber paddle rotates, the rubber paddle contacts the top cardboard of the first lifting assembly and drives the top cardboard to move out of the discharge slot through friction. The cardboard moved out of the loading box enters the printing machine body through the belt conveyor for processing;

[0025] When the sleeve of the first lifting assembly moves upward, the driving gear on the outside meshes with the driven gear on the rotating shaft, and the driven gear drives the reel to rotate through the rotating shaft. The reel reels the pull rope, so that the pull rope pulls the support plate of the first lifting assembly, and the support plate moves to the side away from the cardboard;

[0026] When the sleeve of the second lifting assembly moves downward, the outer driving gear meshes with the driven gear on the rotating shaft, and the driven gear drives the reel to rotate through the rotating shaft, and the reel releases the pull rope. Since the support plate and the sleeve of the second lifting assembly are limited at this time, the released pull rope is loosened, and the second elastic telescopic rod presses down the loose pull rope through the arc-shaped pressing plate to tighten the pull rope;

[0027] S5: As the lifting mechanism continues to operate, the cardboard stacked on the first lifting component gradually decreases;

[0028] As the sleeve of the second lifting assembly moves down to the lower side of the loading box and the positioning hole of the sleeve of the second lifting assembly is inserted by the push rod, the push rod pushes up the positioning block inserted on the upper side of the positioning hole, so that the positioning block moves out of the sleeve, so that the support plate of the second lifting assembly is reset under the elastic force of the first elastic telescopic rod;

[0029] Then, the cardboards stacked on the first lifting assembly are finally loaded, and the support plate of the first lifting assembly moves out of the area between the two auxiliary side plates. The positioning block at the bottom of the support plate is inserted into the positioning hole of the sleeve under the elastic force of the elastic element, so as to realize the positioning of the support plate of the first lifting assembly. At this time, the staff can stack another stack of cardboards on the support plate of the second lifting assembly;

[0030] S6: Then, the lifting motor is controlled to drive the screw of the first lifting assembly to reverse, and the sleeve of the first lifting assembly drives the support plate that has shrunk and shifted to move downward to prepare for the continued placement of subsequent paperboards;

[0031] The sleeve of the second lifting assembly drives the cardboard to move upward through the supporting plate, and realizes the continuous automatic feeding of the cardboard under the action of the material shifting assembly.

[0032] Compared with the prior art, the present invention provides a fully automatic loading carton printing machine and a method of using the same, which have the following beneficial effects:

[0033] 1. The fully automatic loading carton printing machine and the use method thereof realize synchronous loading of other cardboards in the stack while loading a single cardboard through the cooperation of the material shifting component and the lifting mechanism, avoiding the need for manual loading one by one, thereby improving the processing speed; and by setting the first lifting component and the second lifting component, while transferring the material on one stack of cardboards, another stack of cardboards can be placed and loaded, thereby avoiding the waiting time for placing each stack of cardboards and improving the carton printing processing efficiency.

[0034] 2. The fully automatic loading carton printing machine and its use method, through the meshing transmission of the outer driving gear and the driven gear on the rotating shaft during the upward movement of the sleeve, the driven gear drives the reel to rotate through the rotating shaft, the reel reels the pull rope, so that the pull rope pulls the support plate of the first lifting component, and the support plate moves to the side away from the cardboard. After all the cardboards stacked on the first lifting component are finally loaded, the support plate of the first lifting component moves out of the area between the two auxiliary side plates, and the positioning block at the bottom of the support plate is inserted into the positioning hole of the sleeve under the push of the elastic force of the elastic element, so as to realize the positioning of the support plate of the first lifting component, avoid affecting the movement and loading of other cardboards when the support plate moves down later, and ensure the normal automatic loading of cardboards.

[0035] 3. The fully automatic loading carton printing machine and its use method are as follows: the sleeve of the lifting assembly moves down to the lower side of the loading box, the positioning hole of the sleeve is inserted by the push rod, and the push rod pushes up the positioning block inserted on the upper side of the positioning hole, so that the positioning block moves out of the sleeve, and the limit between the sleeve and the support plate is automatically released, so that the support plate is reset under the elastic force of the first elastic telescopic rod, preparing for continuous loading of carton processing.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example 1: Reference Figure 1-7 A fully automatic loading carton printing machine comprises a printing machine body 1, and also comprises:

[0051] A feeding box 2 is arranged at one side of the feeding end of the printing machine body 1, and a belt conveyor 3 is arranged between the feeding box 2 and the printing machine body 1;

[0052] Lifting mechanism, the lifting mechanism is provided with two groups and is symmetrically arranged on both sides of the loading box 2, each group of lifting mechanism includes a first lifting assembly and a second lifting assembly with the same structure, which are used to carry and upload the cardboard 4; and

[0053] A material shifting assembly is arranged in the feeding box 2 and is used to drive the paperboard 4 to move to the belt conveyor 3. A transmission assembly is arranged between the material shifting assembly and the belt conveyor 3;

[0054] A discharge chute 201 for movement of a single paperboard 4 is provided on a side of the loading box 2 close to the belt conveyor 3 , and a loading port 202 is provided on a side of the loading box 2 away from the discharge chute 201 .

[0055] Specifically, when the device is initially working, one of the second lifting assembly and the first lifting assembly is placed on the upper side of the loading box 2, and the other is placed on the lower side of the loading box 2. A stack of cardboards 4 for carton processing is placed on the lifting assembly placed on the lower side of the loading box 2, and then the material-digging assembly is controlled to operate. When the material-digging assembly is in operation, the belt conveyor 3 is driven by the transmission assembly to move, and the belt conveyor 3 conveys the cardboards 4 diverted from the loading box 2 by the material-digging assembly to the printing press body 1. When the lifting mechanism is working, the first lifting assembly and the second lifting assembly alternately move the cardboard 4 upward and convey it. While feeding a single cardboard 4, the synchronous feeding of other cardboards 4 in the stack is achieved, avoiding the need for manual feeding one by one. The loaded cardboards 4 enter the printing press body 1 for processing through the belt conveyor 3, thereby improving the overall processing speed of the carton. By arranging the first lifting assembly and the second lifting assembly, while feeding a stack of cardboards 4, another stack of cardboards 4 can be placed and fed, thereby avoiding the waiting time for placing each stack of cardboards 4, thereby improving the carton processing efficiency.

[0056] Example 2: Reference Figure 1 , Figure 4 , and 6, Figure 7 and Figure 8 A fully automatic loading carton printing machine, based on Example 1, further, the material prying component includes a driving motor 5 fixedly mounted on the loading box 2, a driving shaft 501 connected to the driving motor 5 and arranged in the loading box 2, and a rubber prying piece 502 fixedly mounted on the driving shaft 501, and the rubber prying piece 502 is movably opposed to the uppermost cardboard 4 of the lifting mechanism.

[0057] Specifically, when the material shifting assembly is working, the driving motor 5 is controlled to run, the output shaft of the driving motor 5 drives the driving shaft 501 to rotate, and the driving shaft 501 drives the rubber shifter 502 to rotate. When the rubber shifter 502 rotates, it resists the cardboard 4 on the upper side of the lifting mechanism, and exerts force on the cardboard 4 through the friction force generated during the rotation, so that the cardboard 4 is moved out from the discharge slot 201 of the loading box 2.

[0058] Example 3: Reference Figure 1-11, a carton printing machine with fully automatic feeding, based on Example 2, further, a first lifting component includes a screw 6 rotatably connected to a feeding box 2, a sleeve 601 is threadedly connected to the screw 6, a support plate 602 for placing a cardboard 4 is provided on the sleeve 601, and a winding component for driving the support plate 602 to move horizontally is also provided on the sleeve 601, a first synchronous wheel 7 is provided on the screw 6 of the first lifting component and the screw 6 of the second lifting component, a first synchronous belt is provided between the multiple first synchronous wheels 7, and a lifting motor 605 for driving the screw 6 of the first lifting component to rotate is provided on the feeding box 2.

[0059] Furthermore, the winding assembly includes a support plate 8 fixed on the sleeve 601, the support plate 8 is rotatably connected to a rotating shaft 801, a driven gear 8011 is provided on the rotating shaft 801, a driving gear 6011 meshing with the driven gear 8011 is rotatably connected to the sleeve 601, the driving gear 6011 is slidably connected to the screw 6, a reel 8012 is provided on the rotating shaft 801, a pull rope 8013 is wound around the reel 8012, one end of the pull rope 8013 away from the reel 8012 passes through the sleeve 601 and is connected to the support plate 602, and a first elastic telescopic rod 604 is provided at one end of the support plate 602 between the first connecting plate and the sleeve 601.

[0060] Furthermore, a guide groove 9 is formed in the screw rod 6 along its axial direction, and a guide bar 901 which slides in the guide groove 9 is fixed on the driving gear 6011 .

[0061] Furthermore, a movable groove 11 is provided at the bottom of the support plate 602, and a positioning block 111 is slidably connected in the movable groove 11. An elastic element 112 is arranged between the positioning block 111 and the inner wall of the movable groove 11. The elastic element 112 can use a spring, but is not limited to a spring. Any component that can be squeezed and deformed and elastically reset can be used. An extrusion slope that is movably opposed to the sleeve 601 is provided on the side of the positioning block 111 away from the elastic element 112. A positioning hole 6012 for inserting the positioning block 111 is provided on the sleeve 601. A top rod 203 that is movably opposed to the positioning block 111 is fixedly provided at the bottom of the loading box 2.

[0062] Furthermore, auxiliary side panels 12 are provided on the inner walls of both sides of the loading box 2 , and the two auxiliary side panels 12 are movably abutted against the two sides of the paperboard 4 respectively.

[0063] Specifically, when the device is initially working, the sleeve 601 of the second lifting assembly drives the support plate 602 to be placed on the upper side of the loading box 2, and the support plate 602 of the second lifting assembly is pulled up by the winding assembly, and the sleeve 601 of the first lifting assembly drives the support plate 602 to be placed on the lower side of the loading box 2, and the support plate 602 of the first lifting assembly is not pulled up by the winding assembly, and then a stack of paperboards 4 to be processed and printed is placed on the support plate 602 of the first lifting assembly;

[0064] The driving motor 5 and the lifting motor 605 are controlled to work. When the driving motor 5 is working, the rubber paddle 502 is driven to rotate on the upper side of the loading box 2 through the driving shaft 501. When the lifting motor 605 is working, the screw 6 of the first lifting assembly is driven to rotate vertically in the loading box 2;

[0065] As the screw 6 rotates, the sleeve 601 of the first lifting assembly drives the paperboard 4 to move upward through the support plate 602, and the sleeve 601 of the second lifting assembly drives the support plate 602 to move downward;

[0066] After the first lifting assembly works, the paperboard 4 at the first layer moves to be flush with the discharge slot 201. As the rubber paddle 502 rotates, the rubber paddle 502 contacts the paperboard 4 at the top layer of the first lifting assembly and drives the paperboard 4 at the top layer to move out of the discharge slot 201 through friction. The paperboard 4 moved out of the loading box 2 enters the printing machine body 1 through the belt conveyor 3 for processing.

[0067] When the sleeve 601 of the first lifting assembly moves upward, the driving gear 6011 on the outside is meshed with the driven gear 8011 on the rotating shaft 801 for transmission, and the driven gear 8011 drives the reel 8012 to rotate through the rotating shaft 801, and the reel 8012 reels the pull rope 8013, so that the pull rope 8013 pulls the support plate 602 of the first lifting assembly, and the support plate 602 moves to the side away from the paperboard 4;

[0068] When the sleeve 601 of the second lifting assembly moves downward, the outer driving gear 6011 meshes with the driven gear 8011 on the rotating shaft 801 for transmission, and the driven gear 8011 drives the reel 8012 to rotate through the rotating shaft 801, and the reel 8012 releases the pull rope 8013. Since the support plate 602 and the sleeve 601 of the second lifting assembly are limited at this time, the released pull rope 8013 is loosened, and the second elastic telescopic rod 10 presses down the loose pull rope 8013 through the arc-shaped pressing plate 1001, so that the pull rope 8013 is tightened;

[0069] As the lifting mechanism continues to operate, the cardboards 4 stacked on the first lifting assembly gradually decrease;

[0070] As the sleeve 601 of the second lifting assembly moves downward to the lower side of the loading box 2, and the positioning hole 6012 of the sleeve 601 of the second lifting assembly is inserted by the push rod 203, the push rod 203 pushes up the positioning block 111 inserted on the upper side of the positioning hole 6012, so that the positioning block 111 moves out of the sleeve 601, so that the support plate 602 of the second lifting assembly is reset under the elastic force of the first elastic telescopic rod 604;

[0071] Finally, all the paperboards 4 stacked on the first lifting assembly are loaded. At this time, the support plate 602 of the first lifting assembly moves out of the area between the two auxiliary side plates 12. The positioning block 111 at the bottom of the support plate 602 is inserted into the positioning hole 6012 of the sleeve 601 under the elastic force of the elastic element 112, so as to realize the positioning of the support plate 602 of the first lifting assembly, so as to avoid affecting the movement and loading of other paperboards 4 when the support plate 602 moves downward, and ensure the normal automatic loading of the paperboards 4.

[0072] Then, the lifting motor 605 is controlled to drive the screw 6 of the first lifting assembly to reverse, and the sleeve 601 of the first lifting assembly drives the support plate 602 that has shrunk and shifted to move downward to prepare for the subsequent placement of the paperboard 4;

[0073] The sleeve 601 of the second lifting assembly drives the cardboard 4 to move upward through the support plate 602, and realizes the continuous automatic feeding of the cardboard 4 under the action of the material shifting assembly, effectively reducing the workload and work intensity of the staff, thereby improving the overall processing efficiency of the carton.

[0074] Example 4: Reference Figure 1 , Figure 4 , and 6, Figure 7 and Figure 8 A fully automatic loading carton printing machine, based on Example 3, further, the sleeve 601 is also connected to the second elastic telescopic rod 10 through the second connecting plate, and the bottom of the second elastic telescopic rod 10 is provided with an arc-shaped pressing plate 1001, and the arc-shaped pressing plate 1001 is movably opposed to the pull rope 8013.

[0075] Specifically, by elastically setting an arc-shaped pressure plate 1001 on the sleeve 601, the support plate 602 and the sleeve 601 can be relaxed as the pull rope 8013 is released during the period of being limited downward by the positioning block 111, and the second elastic telescopic rod 10 resumes its stretching and presses down the relaxed pull rope 8013 through the arc-shaped pressure plate 1001. It should be noted that when the pull rope 8013 is wound up, the second elastic telescopic rod 10 is lifted and contracted due to the force applied to the arc-shaped pressure plate 1001, thereby preventing the pull rope 8013 from shaking randomly and affecting the meshing transmission between the gears and the feeding and conveying of the cardboard 4, thereby ensuring the stable feeding of the cardboard 4.

[0076] Example 5: Reference Figure 1 and Figure 3A fully automatic loading carton printing machine, based on Example 2, further, the transmission assembly includes two second synchronous wheels 13 arranged on the driving shaft 501 and the input shaft of the belt conveyor 3, and a second synchronous belt is arranged between the two second synchronous wheels 13.

[0077] Specifically, when the driving shaft 501 rotates, the input shaft of the belt conveyor 3 is driven to rotate through the second synchronous wheel and the second synchronous belt, thereby enabling the belt conveyor 3 to perform transmission work through the belt.

[0078] The present invention also discloses a method for using a fully automatic loading carton printing machine, comprising the following steps:

[0079] S1: When the device is initially working, the sleeve 601 of the second lifting assembly drives the support plate 602 to be placed on the upper side of the loading box 2, and the support plate 602 of the second lifting assembly is pulled up by the winding assembly, the sleeve 601 of the first lifting assembly drives the support plate 602 to be placed on the lower side of the loading box 2, and the support plate 602 of the first lifting assembly is not pulled up by the winding assembly, and then a stack of paperboards 4 to be processed and printed is placed on the support plate 602 of the first lifting assembly, and the stacked paperboards 4 are placed between the two auxiliary side plates 12;

[0080] S2: Control the driving motor 5 and the lifting motor 605 to work. When the driving motor 5 is working, the driving shaft 501 drives the rubber paddle 502 to rotate on the upper side of the loading box 2. When the lifting motor 605 is working, the screw 6 of the first lifting assembly is driven to rotate vertically in the loading box 2.

[0081] When the driving shaft 501 rotates, the input shaft of the belt conveyor 3 is driven to rotate through the second synchronous wheel and the second synchronous belt, thereby making the belt conveyor 3 perform transmission work through the belt;

[0082] S3: As the screw 6 rotates, the sleeve 601 of the first lifting assembly drives the paperboard 4 to move upward through the support plate 602, and the sleeve 601 of the second lifting assembly drives the support plate 602 to move downward;

[0083] S4: After the first lifting assembly works, the cardboard 4 on the first layer moves to be flush with the discharge slot 201. As the rubber paddle 502 rotates, the rubber paddle 502 contacts the cardboard 4 on the uppermost layer of the first lifting assembly and drives the cardboard 4 on the uppermost layer to move out of the discharge slot 201 through friction. The cardboard 4 moved out of the loading box 2 enters the printing press body 1 through the belt conveyor 3 for processing.

[0084] When the sleeve 601 of the first lifting assembly moves upward, the driving gear 6011 on the outside is meshed with the driven gear 8011 on the rotating shaft 801 for transmission, and the driven gear 8011 drives the reel 8012 to rotate through the rotating shaft 801, and the reel 8012 reels the pull rope 8013, so that the pull rope 8013 pulls the support plate 602 of the first lifting assembly, and the support plate 602 moves to the side away from the paperboard 4;

[0085] When the sleeve 601 of the second lifting assembly moves downward, the outer driving gear 6011 meshes with the driven gear 8011 on the rotating shaft 801 for transmission, and the driven gear 8011 drives the reel 8012 to rotate through the rotating shaft 801, and the reel 8012 releases the pull rope 8013.
