Description

Technical Field

[0001] The present invention relates to an automatic carton gluing device and a method for using the same. Background Art

[0002] A carton gluer is an automatic packaging device mainly used for folding and gluing the printed and die-cut cardboard into a formed shape, which is the last process in the processing of packaging boxes. The carton gluer improves production efficiency and reduces labor costs through advanced processes and technologies.

[0003] The carton will go through processes such as pre-folding, edge folding, glue application, and glue pressing in the carton gluer. Among them, the glue application and glue pressing processes determine the firmness of the formed carton. Common glue application methods include roller gluing, brush gluing, etc.; roller gluing means that the roller completes glue application while rolling on the carton, and brush gluing means that the brush is connected to the glue box, and the glue is distributed on the brush through the fluidity and permeability of the glue. When the carton passes through the brush, the glue will be coated on the edge of the carton.

[0004] Whether it is brush gluing or roller gluing, finally a continuous linear glue line appears on the carton; due to the certain tension and adhesiveness of the glue, when applying glue, the glue coated on the carton will pull the glue on the brush onto the carton, resulting in the amount of glue on the carton being greater than the designed value. In the subsequent glue pressing process, the glue will be pressed and spread, resulting in the phenomenon of internal adhesion (the cartons are bonded together and cannot be formed) or external adhesion (the cartons are adhered to the conveyor belt and contaminate the production line), affecting the orderly progress of the entire production.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which may be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0031] Please refer to Figures 1 to 11 , in the embodiment of the present invention, an automatic carton gluing device and its use method include a frame 1; a plurality of conveyor belts 2 for feeding are rotatably installed on the frame 1; A glue box 3 and a fixed disk 5 are installed on the frame 1; the fixed disk 5 and the glue box 3 are communicated through a conduit 4; A plurality of dispensing mechanisms are provided on the frame 1; the dispensing mechanism includes a glue outlet sleeve 801; a sliding block 11 is slidably and sealingly arranged in the glue outlet sleeve 801; a first glue outlet groove 1101 is formed on the sliding block 11; a rotating block 12 is rotatably installed on the sliding block 11; a second glue outlet groove 1201 that can cooperate with the first glue outlet groove 1101 is formed on the rotating block 12; A switching mechanism cooperating with the dispensing mechanism is provided on the frame 1; the switching mechanism can drive multiple groups of the glue outlet sleeves 801 to rotate closer to or away from the conveyor belt 2; during the process of the glue outlet sleeve 801 approaching the conveyor belt 2, the sliding block 11 will move away from the center of the fixed disk 5; and the first glue outlet groove 1101 and the second glue outlet groove 1201 are in a misaligned state, so as to extrude glue onto the paper box. A glue pressing mechanism for making the glue evenly distributed is further provided on the frame 1.

[0032] Taking the embodiment combined with all the features described in this application as an example, during use, pre-folding, edge-folding, and dry-glue functional areas are respectively arranged on the frame 1 along the transportation direction of the conveyor belt 2.

[0033] The operator places the paper box blank on the conveyor belt 2, and the conveyor belt 2 will transport the paper box blanks one by one to the other end; during the transportation process, the paper box blanks will be pre-folded and edge-folded.

[0034] The glue box 3 is filled with glue and continuously transports the glue to the fixed disk 5 through the conduit 4.

[0035] During the edge-folding process: the dispensing mechanism and the switching mechanism cooperate with each other to perform non-continuous linear dispensing on the edge of the paper box blank; wherein the switching mechanism drives multiple groups of glue outlet sleeves 801 to rotate, so that multiple groups of glue outlet sleeves 801 approach or move away from the conveyor belt 2 in sequence; the dispensing mechanism first drives the sliding block 11 and the rotating block 12 to slide towards the center of the fixed disk 5 during the process of the glue outlet sleeve 801 approaching the conveyor belt 2, and during the sliding process, the first glue outlet groove 1101 and the second glue outlet groove 1201 cooperate with each other so that the glue can smoothly reach the outlet end of the glue outlet sleeve 801. When the rotating block 12 is about to reach the end of the sliding stroke, it will rotate so that the first glue outlet groove 1101 and the second glue outlet groove 1201 are disengaged from the cooperation state to close the glue outlet sleeve 801 and the fixed disk 5.

[0036] Then the sliding block 11 and the rotating block 12 slide in the direction away from the fixed disk 5, thereby extruding the glue out of the glue outlet sleeve 801, and a dispensing action is completed when the glue outlet sleeve 801 is perpendicular to the conveyor belt 2, and the extruded glue will fall on the edge of the paper box blank.

[0037] After the paper box is edge-folded, it will be transported to the glue pressing mechanism for glue pressing. Through the glue pressing mechanism, the glue on the paper box can be evenly coated, and the action of the glue pressing mechanism can make the non-continuous linear glue combine with each other (the originally unconnected glue dots diffuse around under the glue pressing action of the glue pressing mechanism, and the diffusion ranges of the adjacent glue dots overlap each other), so as to avoid the phenomenon of weak adhesion or broken-point adhesion, thereby improving the adhesion quality.

[0038] Through the mutual cooperation of the switching mechanism, the dispensing mechanism and the pressing glue mechanism, discontinuous linear dispensing is carried out on the edge of the paper box blank, which can effectively control the amount of glue and the diffusion area on the paper box, avoid the occurrence of glue sticking inside or outside, so as to improve production efficiency and quality; and the switching mechanism can prevent the components of the dispensing mechanism from working fatigue, thereby reducing the maintenance frequency of the device and increasing the service life of the device.

[0039] In another embodiment of the present invention, the switching mechanism includes a dispensing motor 7 installed on the frame 1; a turntable 8 is installed on the output end of the dispensing motor 7; the turntable 8 is rotationally and sealingly connected to the fixed disk 5; and there is a space for storing glue between the two.

[0040] Taking the embodiment combined with all the features described in this application as an example, when in use, when the dispensing motor 7 operates, it will drive the turntable 8 to rotate. The glue outlet sleeves 801 are equidistantly distributed on the turntable 8, so the turntable 8 can drive the glue outlet sleeves 801 to rotate.

[0041] The glue in the glue box 3 is transported to the space between the turntable 8 and the fixed disk 5 through the conduit 4, and the glue outlet sleeve 801 is communicated with the space for storing glue, so the glue can enter the glue outlet sleeve 801 to facilitate subsequent dispensing by the dispensing mechanism.

[0042] The switching mechanism drives the turntable 8 to rotate, and multiple glue outlet sleeves 801 approach or move away from the conveyor belt 2 in turn and orderly. And during the process of the glue outlet sleeve 801 approaching the conveyor belt 2, the dispensing mechanism will perform a dispensing action, which can effectively prevent the components on the dispensing structure from working fatigue, thereby reducing the maintenance efficiency and increasing the service life of the device.

[0043] In another embodiment of the present invention, the dispensing mechanism further includes a slide bar 9 fixedly connected to the slider 11; and the slide bar 9 is slidably fitted with the turntable 8; a first protruding column 901 is installed on the slide bar 9; a fixed block 6 is installed on the fixed disk 5; and a fitting groove slidably fitted with the first protruding column 901 is formed on the fixed block 6.

[0044] In another embodiment of the present invention, the fitting groove includes an arc-shaped chute 601, a first inclined chute 602, a second inclined chute 603 and a third inclined chute 604; one end of the arc-shaped chute 601 is communicated with one end of the first inclined chute 602; the other end of the first inclined chute 602 is communicated with one end of the second inclined chute 603; the other end of the second inclined chute 603 is communicated with one end of the third inclined chute 604; and the other end of the third inclined chute 604 is communicated with the other end of the arc-shaped chute 601.

[0045] Taking the embodiment combined with all the features described in this application as an example, when in use, when the turntable 8 rotates, it will drive the glue outlet sleeve 801 to rotate, thereby driving the sliding block 11 to rotate, and then driving the sliding rod 9 to rotate, so as to drive the first protruding column 901 to slide in the fitting groove.

[0046] When the first protruding column 901 slides in the arc-shaped chute 601, the sliding block 11 remains relatively stationary in the glue outlet sleeve 801. At this time, the first glue outlet groove 1101 and the second glue outlet groove 1201 are in a relatively misaligned state (disengaged from the fitting state), so as to block the glue outlet sleeve 801 and prevent glue from flying out and contaminating the device. When the first protruding column 901 slides in the first inclined groove 602, the sliding block 11 will drive the rotating block 12 to slide a small distance away from the center of the fixed disk 5. During this process, the rotating block 12 will rotate, so that the first glue outlet groove 1101 and the second glue outlet groove 1201 are aligned with each other (fitting state), facilitating the passage of glue.

[0047] When the first protruding column 901 slides in the second inclined groove 603, the sliding block 11 will drive the rotating block 12 to approach the center; during this process, the first glue outlet groove 1101 and the second glue outlet groove 1201 remain in the fitting state first; at this time, the glue will converge towards the outlet end of the glue outlet sleeve 801; then the rotating block 12 will rotate to disengage the first glue outlet groove 1101 from the second glue outlet groove 1201 to re-block the glue outlet sleeve 801.

[0048] When the first protruding column 901 slides in the third inclined groove 604, the rotating block 12 and the sliding block 11 will move away from each other, so as to squeeze the glue out of the glue outlet sleeve 801.

[0049] Due to the relatively stable stroke of the sliding block 11, the amount of glue for each dispensing is relatively stable; and when the first glue outlet groove 1101 and the second glue outlet groove 1201 are disengaged from the fitting state, the connection between the glue in the glue outlet sleeve 801 and the glue in the fixed disk 5 will be cut off, avoiding that during the dispensing process, due to the surface tension and adhesion of the glue itself, glue still flows out after the glue is extruded, resulting in an increase in the amount of glue and affecting subsequent processing.

[0050] Through the mutual cooperation of the switching mechanism, the dispensing mechanism and the glue pressing mechanism, non-continuous linear dispensing is performed on the edge of the paper box blank, which can effectively control the amount of glue and the diffusion area on the paper box, avoid the occurrence of glue sticking inside or outside, thereby improving production efficiency and quality; and the switching mechanism can prevent the components of the dispensing mechanism from working fatigue, thereby reducing the maintenance frequency of the device and increasing the service life of the device.

[0051] In another embodiment of the present invention, a rotating sleeve 10 fixedly connected to the rotating block 12 is rotatably mounted on the sliding rod 9; an opening and closing groove is formed in the rotating sleeve 10; a fixing ring 802 sleeved on the rotating sleeve 10 is mounted on the turntable 8; a second protruding column 803 slidably engaged with the opening and closing groove is mounted on the fixing ring 802.

[0052] In another embodiment of the present invention, the opening and closing groove includes a first vertical groove 1001, a conducting inclined groove 1002, a second vertical groove 1003 and a closing inclined groove 1004; one end of the first vertical groove 1001 is communicated with one end of the conducting inclined groove 1002; the other end of the conducting inclined groove 1002 is communicated with one end of the second vertical groove 1003; the other end of the second vertical groove 1003 is communicated with one end of the closing inclined groove 1004; the other end of the closing inclined groove 1004 is communicated with the other end of the first vertical groove 1001.

[0053] Taking the embodiment combined with all the features described in this application as an example, when the first protruding column 901 slides in the first inclined groove 602, the second protruding column 803 will slide in the conducting inclined groove 1002, thereby driving the rotating sleeve 10 to rotate, so that the rotating block 12 slides on the sliding block 11, so that the first glue outlet groove 1101 and the second glue outlet groove 1201 are disengaged from the mating state.

[0054] When the first protruding column 901 slides in the second inclined groove 603, the second protruding column 803 will first slide in the second vertical groove 1003. During this process, the rotating sleeve 10 does not rotate, so that the rotating block 12 and the sliding block 11 remain relatively stationary. Then the second protruding column 803 will also slide in the closing inclined groove 1004 to drive the rotating sleeve 10 to rotate, so that the rotating block 12 rotates on the sliding block 11, so that the first glue outlet groove 1101 and the second glue outlet groove 1201 are in a mating state again.

[0055] When the first protruding column 901 slides in the third inclined groove 604, the second protruding column 803 will slide in the first vertical groove 1001, and the rotating block 12 and the sliding block 11 remain relatively stationary and slide in the glue outlet sleeve 801.

[0056] When the first protruding column 901 slides in the arc-shaped chute 601, the second protruding column 803 remains stationary, and the second protruding column 803 is located at the connection of the first vertical groove 1001 and the conducting inclined groove 1002.

[0057] When the first glue outlet groove 1101 and the second glue outlet groove 1201 are disengaged from the mating state, the connection between the glue in the glue outlet sleeve 801 and the glue in the fixed disk 5 will be cut off, avoiding that during the dispensing process, due to the tension and adhesion of the glue itself, there is still glue flowing out after the glue is extruded, resulting in an increase in the amount of glue and affecting subsequent processing.

[0058] Through the mutual cooperation of the switching mechanism, the dispensing mechanism and the pressing mechanism, discontinuous linear dispensing is performed on the edge of the paper box blank, which can effectively control the amount of glue and the diffusion area on the paper box, avoid the occurrence of glue sticking inside or outside, thereby improving production efficiency and quality; and the switching mechanism can prevent the components of the dispensing mechanism from working fatigue, thereby reducing the maintenance frequency of the device and increasing the service life of the device.

[0059] In another embodiment of the present invention, the pressing mechanism includes a mounting frame 13 mounted on the frame 1; a pressing motor 14 is mounted on the mounting frame 13; a rotating column 15 is mounted on the output end of the pressing motor 14; a third protruding column 1501 is mounted on the rotating column 15; a sliding sleeve 16 is sleeved on the rotating column 15; a lifting groove slidably fitted with the third protruding column 1501 is formed on the sliding sleeve 16; an extrusion sleeve 17 fixedly connected to the sliding sleeve 16 is slidably mounted on the mounting frame 13; an extrusion column 18 is slidably mounted in the extrusion sleeve 17; an extrusion disc 1801 is mounted on the extrusion column 18; a spring 19 is provided on the extrusion sleeve 17; both ends of the spring 19 abut against the extrusion sleeve 17 and the extrusion column 18 respectively; a hinge rod 20 is hinged on the extrusion sleeve 17; a connecting rod 21 hinged to the hinge rod 20 is rotatably mounted on the extrusion disc 1801; a pressing wheel 22 is rotatably mounted on the hinge rod 20.

[0060] In another embodiment of the present invention, the lifting groove includes an extrusion inclined groove 1601, a pressure relief inclined groove 1602 and a flat groove 1603; one end of the extrusion inclined groove 1601 is communicated with one end of the pressure relief inclined groove 1602; the other end of the pressure relief inclined groove 1602 is communicated with one end of the flat groove 1603; the other end of the flat groove 1603 is communicated with the other end of the extrusion inclined groove 1601.

[0061] Taking the embodiment combined with all the features described in this application as an example, when in use, when the pressing motor 14 rotates, it will drive the rotating column 15 to rotate, thereby driving the third protruding column 1501 to slide in the lifting groove.

[0062] When the third protruding column 1501 slides in the extrusion inclined groove 1601, the sliding sleeve 16 will drive the extrusion sleeve 17 to move towards the conveyor belt 2; and the extrusion sleeve 17 will drive the extrusion column 18 and the extrusion disc 1801 to move synchronously through the spring 19; when the extrusion disc 1801 contacts the paper box, the extrusion sleeve 17 still continues to move, thereby compressing the spring 19; the extrusion column 18 will slide inwards in the extrusion sleeve 17, thereby driving the hinge rod 20 to rotate through the connecting rod 21, so as to drive the pressing wheel 22 to rotate.

[0063] By rotating the two pressing wheels 22 in opposite directions respectively, during the rotation process, the pressing wheels 22 are always tangent to the extrusion disc 1801, so as to extrude the paper box from the relatively middle part of the paper box to both sides, so that the discontinuous linear glue is pressed and diffused to increase the bonding area. As the glue diffuses, the originally unconnected glue dots will combine with each other, thereby improving the bonding effect.

[0064] When the third protruding column 1501 slides in the pressure-relieving chute 1602, the sliding sleeve 16 will drive the extrusion sleeve 17 away from the conveyor belt 2, and under the elastic force of the spring 19, the extrusion column 18 will slide outwards in the extrusion sleeve 17, thereby driving the articulated rod 20 to rotate and reset through the connecting rod 21.

[0065] When the third protruding column 1501 slides in the flat groove 1603, the sliding sleeve 16 remains in place. At this time, the paper box that has undergone glue pressing processing will be passed through, and the next paper box will be conveyed under the glue pressing mechanism.

[0066] In another embodiment of the present invention, the pressing wheel 22 is made of elastic rubber material.

[0067] Taking the embodiment combined with all the features described in this application as an example, when in use, the rubber pressing wheel 22 will deform slightly when contacting the paper box, which can avoid the appearance of indentations on the paper box, thereby improving the production quality.

[0068] A method for using an automatic carton gluing device as described above includes the following steps: Step 1: Stack the paper box blanks on one end of the frame 1, and the conveyor belt 2 can convey the blanks one by one to the other end; during the conveying process, the blanks will undergo pre-folding and edge-folding processing; Step 2: The glue dotting mechanism and the switching structure will perform discontinuous linear glue dotting on the blank during the edge-folding process of the blank; Step 3: After the blank is edge-folded; the glue pressing mechanism will perform a glue pressing action on the glue-dotted part; Step 4: After the glue pressing is completed, the blank undergoes dry glue processing and is conveyed to the finished product area by the conveyor belt 2.
