Description

Technical Field

[0001] The invention relates to a paper box production line, in particular to a frame forming production line. Background Art

[0002] The frame is an important component of the paper box structure. When the frame is made, after the face paper is laminated on one side of a long strip of paperboard (which can be called a "long strip" and pre-grooved, such as a V-groove), the face paper is folded and wrapped on the other side of the long strip of paperboard, and then the assembled long strip of paperboard with face paper is subjected to frame molding in a frame molding machine, which can be used as the box body of the paper box. For example, in the CN117656582A frame molding machine, not only is an edge wrapping mechanism required to fold the face paper and wrap it on the other side of the long strip of paperboard, but a frame molding mechanism is also required to complete the enclosure and molding of the frame. The materials are fed one by one for processing, and the efficiency is relatively slow.

[0003] In addition, when glue (such as white glue) is used to assemble and mount materials (including facial tissue and long strips of cardboard), the glue needs time to work. To ensure that the assembly and mounting are firm, an oven can be used to act on the glue to make the glue work as quickly as possible, shortening the glue reaction time. However, the electricity consumption will also increase, increasing production costs. Alternatively, the material delivery speed can be slowed down to increase the reaction time of the glue. Slowing down the material delivery speed will slow down the entire production and processing speed. Summary of the invention

[0038] The output end of the first conveyor belt 15 is connected with the input end of the second conveyor belt 3, that is, the first conveyor belt 15 can convey the material (the material of the long paperboard that has been positioned and pasted on the upper side of the surface paper) to the second conveyor belt 3, and the second conveyor belt 3 will continue to convey the material. The output end of the second conveyor belt 3 is connected with the input end of the third conveyor belt 131, that is, the second conveyor belt 3 can convey the material to the third conveyor belt 131, and the third conveyor belt 131 will continue to convey the material.

[0039] The folding device 2 includes a folding paper board 20, and the folding device 2 is arranged on the left side of the second conveyor belt 3.

[0040] The folding device 2 includes a wrapping folding paper board 20 (or wrapping board). The folding device 2 is used to fold the surface paper on the lower side of the long paperboard (i.e., paperboard) and wrap it around the edge of the long paperboard (i.e., wrapping). The folding device 2 is arranged on the left side of the second conveyor belt 3, wherein the second conveyor belt 3 is used to transfer the material (of the long paperboard that has been positioned and pasted on the upper side of the surface paper). The second conveyor belt 3 transfers the material to the folding device 2 to cooperate with the wrapping.

[0041] The left and right transverse moving frames 4 are arranged above the second conveyor belt 3. The second conveyor belt 3 conveys the material (the long paperboard which has been positioned and pasted on the upper side of the facial paper) from the back to the front, and the left and right transverse moving frames 4 can move left and right above the second conveyor belt 3. The left and right transverse moving frames 4 are provided with a first lifting facial paper suction component 40, a lifting paperboard pressing component 41, a second lifting facial paper suction component 42 and a lifting paper gauge component 43, which can not only move left and right together with the left and right transverse moving frames 4, but also can be lifted and lowered accordingly on the left and right transverse moving frames 4.

[0042] The first lifting and sucking facial paper component 40 is arranged on the left side of the lifting and pressing paper component 41, the lifting and pressing paper component 41 and the second lifting and sucking facial paper component 42 are synchronously lifted and lowered, the second lifting and sucking facial paper component 42 is arranged on the front side and / or the rear side of the lifting and pressing paper component 41, the bottom of the lifting and pressing paper component 41 has a pressure surface 410, and the lifting and pressing paper component 41 is also provided with a suction plate device 411 for sucking the paperboard downward, and the lifting and paper gauge component 43 is arranged on the right side of the lifting and pressing paper component 41. On the left and right transverse moving frame 4, the lifting and pressing paper component 41 and the second lifting and sucking facial paper component 42 are located between the first lifting and sucking facial paper component 40 and the lifting and pressing paper component 41.

[0043] The first lifting and lowering facial paper suction component 40 is used to cooperate in sucking the facial paper portion to be wrapped. When the lifting and lowering paperboard pressing component 41 sucks and moves the paperboard, the facial paper portion is sucked for corresponding lifting and horizontal movement to prevent the facial paper portion from drooping down and affecting the transfer, thereby ensuring that the relative positions of the paperboard and the facial paper after the movement are in a stable state.

[0044] The pressure surface 410 at the bottom of the lifting and pressing paperboard component 41 can not only be used to press the paperboard on the second conveyor belt 3 (stabilize the position of the paperboard) so that the edge folding paperboard 20 folds the surface paper part to be edged upward and wraps it inward on the paperboard to avoid displacement of the paperboard (i.e., long strips of paperboard) and ensure the edge wrapping effect, but also the suction plate device 411 of the lifting and pressing paperboard component 41 can be used to suck the paperboard so that the lifting and pressing paperboard component 41 can suck and move the paperboard; the second lifting and pressing paperboard suction component 42 can cooperate to suck the surface paper part on the front or rear side of the paperboard (used for overlapping when the frame is enclosed and formed). When the lifting and pressing paperboard component 41 sucks and moves the cardboard, the surface paper part is sucked for corresponding lifting and horizontal movement to avoid the surface paper part drooping down and affecting the transfer, thereby ensuring that the relative positions of the cardboard and the surface paper after movement are in a stable state.

[0045] The lifting paper gauge component 43 is used to push the paperboard on the second conveyor belt 3 to correct the relative position after being lifted into place, thereby ensuring the hemming effect.

[0046] The right side of the second conveyor belt 3 is also provided with a side push paper gauge component, which is used to push the paperboard on the second conveyor belt 3 (towards the left) to correct the relative position and ensure the hemming effect. The side push paper gauge component 5 can be driven by the cylinder 50 to move left and right along the guide rail 51.

[0047] Among them, the frame long strip lifting and folding equipment 1 can not only operate in single-material mode, but also in double-material mode, thereby improving the efficiency of frame processing and manufacturing.

[0048] When the single-material mode is running, the face paper A is located at the left side of the second conveyor belt 3 for feeding and conveying, and the cardboard A is placed on the face paper A, and then conveyed by the second conveyor belt 3 to stop at the folding device 2, and the lifting and lowering paper gauge components 43 on the left and right transverse moving frames 4 descend and move (to the left) with the left and right transverse moving frames 4, and push the cardboard A on the second conveyor belt 3 (to the left) to correct the relative position, then, the lifting and lowering cardboard pressing components 41 on the left and right transverse moving frames 4 descend to press the cardboard A, stabilize the relative position of the cardboard A on the second conveyor belt 3, and the folding device 2 then folds the edge of the face paper A on the lower side of the cardboard A and wraps it around the edge of the cardboard A (i.e., wrapping), wherein the edge of the face paper A is folded upward and wrapped inward on the cardboard A to complete the wrapping, and the folding device 2, the lifting and lowering cardboard pressing components 41, the lifting and lowering paper gauge components 43, the left and right transverse moving frames 4, etc. are reset to wait for the next work, and the second conveyor belt 3 continues to convey the wrapped cardboard forward.

[0049] When the double-material mode is in operation, the face paper A and the face paper B are placed side by side on the second conveyor belt 3, the cardboard A is placed on the face paper A, and the cardboard B is placed on the face paper B, and then conveyed by the second conveyor belt 3 to the folding device 2, and the face paper A and the cardboard A on the left side of the second conveyor belt 3 are processed to complete the folding. During this process, the lifting and lowering paper gauge components 43 on the left and right transverse moving frames 4 descend and move (to the left) with the left and right transverse moving frames 4, and push the cardboard A on the second conveyor belt 3 (to the left) to correct the relative position, and then the lifting and lowering cardboard pressing components 4 on the left and right transverse moving frames 4 are lowered. 1 descends to press the cardboard A, stabilizes the relative position of the cardboard A on the second conveyor belt 3, and the folding device 2 then folds the edge of the face paper A on the lower side of the cardboard A and wraps it around the edge of the cardboard A (i.e., wrapping), wherein the edge of the face paper A is folded upward and wrapped inward on the cardboard A; in addition, the face paper B and cardboard B on the right side of the second conveyor belt 3 are pushed sideways by the side-pushing paper gauge component (to the left) to correct the relative position, and after the face paper A and cardboard A on the left side are wrapped, the left and right transverse moving frames 4 move sideways to the right, and the first lifting face paper suction component 40, the lifting cardboard pressing component 41, and the second lifting face paper suction component 42 are used to pull the face paper B and cardboard B out of the way. The component 42 cooperates with the lifting to suck and lift the facial paper B and the cardboard B (to realize the lifting conveying, at this time, the second conveyor belt 3 can move forward to convey the facial paper A and the cardboard A on the left side that have completed the edge wrapping to make room), and the left and right transverse moving frames 4 move horizontally to the left, and the first lifting facial paper sucking component 40, the lifting cardboard pressing component 41, and the second lifting facial paper sucking component 42 cooperate with the lifting to release the facial paper B and the cardboard B on the left side of the second conveyor belt 3. At this time, the first lifting facial paper sucking component 40 can rise to the avoidance position, and the lifting cardboard pressing component 41 is in a position to press the cardboard B (and the facial paper B under it) to On the second conveyor belt 3, and the relative positions of the facial paper B and the cardboard B have been corrected by the side-pushing paper gauge component (to the left) (no need to additionally correct their positions by the lifting paper gauge component 43, and the edge can be wrapped in time, with high efficiency), the folding device 2 can fold the edge of the facial paper B on the lower side of the cardboard B and wrap it around the edge of the cardboard B (i.e., wrapping), wherein the edge of the facial paper B is folded upward and wrapped inward on the cardboard B, and then the second conveyor belt 3 conveys it forward, and other side-by-side materials are conveyed to the folding device 2 by the second conveyor belt 3 for the next round of wrapping operation.

[0050] The frame strip lifting and folding device 1 folds the face paper on the lower side of the long cardboard used to make the frame and covers the edge of the long cardboard. Moreover, the frame strip lifting and folding device 1 can not only be used for the edge wrapping and folding of a single cardboard (i.e., single-material mode) (to achieve the folding and covering of the face paper on the other side of the long cardboard); it can also be used for the edge wrapping and folding of a double cardboard (i.e., double-material mode). Cardboards with face paper on the lower side can be placed on the left and right sides of the second conveyor belt 3 at the same time and conveyed to the folding device 2 together. The edge wrapping and folding of the left cardboard is completed first, and then the edge wrapping and folding of the right cardboard is completed after it is sent away, thereby improving efficiency and even cooperating with double-link double-sided paper feeding operations.

[0051] In the frame forming production line, the whole production line is integrated and connected by relying on the first conveyor belt 15, the second conveyor belt 3 and the third conveyor belt 131 (each equipped with a corresponding driving motor); wherein, the frame strip lifting and folding device 1 can be operated not only in single-material mode but also in double-material mode, thereby improving the efficiency of frame processing and manufacturing; in double-material mode, materials (including facial tissue and cardboard) can be supplied side by side to the frame strip lifting and folding device 1 for processing, and when the conveying speeds of the first conveyor belt 15 and the second conveyor belt 3 are relatively slow to extend the reaction time of the glue on the facial tissue (to ensure that the glue can fully play its role and the bonding is more firm), the double-material mode can improve the feeding efficiency by supplying materials side by side and the frame strip lifting and folding device 1 can complete the edge wrapping operation of the materials side by side in sequence, thereby making up for the problem of reduced efficiency caused by the slow conveying speeds of the first conveyor belt 15 and the second conveyor belt 3, so that the whole frame forming production line can not only improve the reaction time of the glue to ensure that the glue can firmly bond the facial tissue and cardboard, but also the efficiency of the whole production line is not low.

[0052] The following optimization or further explanation may be performed based on the above embodiments.

[0053] For example, the conveying paths of the first conveyor belt 15, the second conveyor belt 3 and the third conveyor belt 131 are all arranged from back to front, which is convenient for input and output of materials. The first conveyor belt 15, the second conveyor belt 3 and the third conveyor belt 131 all adopt suction belts to increase the stability of conveying and avoid material displacement.

[0054] It can be further optimized, and the left side of the second conveyor belt 3 is also equipped with a supporting plate 30, which can cooperate to support facial tissue, especially the material located on the left side of the second conveyor belt 3. When the facial tissue exceeds the left edge of the second conveyor belt 3, it can be supported by the supporting plate 30 to prevent it from drooping. The supporting plate 30 is arranged on the front and / or rear side of the edge-wrapped folding paper board 20. The first lifting facial tissue suction component 40 adopts a first air nozzle, the second lifting facial tissue suction component 42 adopts a second air nozzle, the suction plate device 411 adopts air holes, and the air holes are distributed on the pressure surface 410. The lifting and lowering paperboard component 41 adopts a pressure strip or a pressure plate; they can adopt a negative pressure air source to cooperate to achieve suction and release by suction.

[0055] Among them, the hemming operation of the hemming folding paper board 20 (i.e., the hemming board) is a mature technology. For example, the hemming folding paper board 20 can be lifted and moved left and right, and can be driven by motors 21 and 22 respectively equipped with corresponding screw nut mechanisms 23 and 24 to lift and move left and right (laterally), or can be driven by cylinders to lift and move left and right.

[0056] In addition, the front and rear parts of the left and right transverse frames 4 are respectively connected to the transverse seat 44, and the transverse seat 44 is equipped with a transverse driving device 45 (such as a linear module, etc.). The left and right transverse frames 4 are mounted on the transverse seat 44 and move left and right along with the transverse seat 44. For example, a front bracket 31 and a rear bracket 32 ​​are arranged across the second conveyor belt 3, and the transverse seat 44 is respectively arranged on the front bracket 31 and the rear bracket 32.

[0057] The lifting and lowering cardboard pressing part 41 is connected with the second lifting and lowering absorbent paper part 42, which has better synchronization, consistent lifting and lowering movements, and can also share a common power drive, making it more stable when moving and removing materials, and the stability of the relative position of the materials can also be guaranteed.

[0058] In addition, a connecting frame 46 may be provided between the second lifting and sucking facial paper component 42 and the lifting and pressing paperboard component 41, and the second lifting and sucking facial paper component 42 and the lifting and pressing paperboard component 41 are connected through the connecting frame 46, for example, the connecting frame 46 is arranged at the front side and / or the rear side of the lifting and pressing paperboard component 41. In addition, the second lifting and sucking facial paper component 42 is arranged on the connecting frame 46 for front and rear position adjustment (for example, a longitudinal groove is arranged on the connecting frame 46 for the second lifting and sucking facial paper component 42 to be installed), so as to adjust the front and rear position along the longitudinal direction, adapt to different material sizes and adjust the position to ensure the stability of sucking the paperboard and facial paper.

[0059] For another example, the first lifting and sucking facial paper component 40 is equipped with a first lifting driving source 400, the lifting and pressing paper component 41 and the second lifting and sucking facial paper component 42 are equipped with a second lifting driving source 412, and the lifting and pressing paper component 43 is equipped with a third lifting driving source 431. The corresponding lifting driving sources drive them to perform corresponding lifting actions on the left and right transverse moving frames 4. For example, the first lifting driving source 400, the second lifting driving source 412, and the third lifting driving source 431 can be selected from cylinders or motors.

[0060] In addition, the frame forming mechanism 132 is arranged on the left or right side of the third conveyor belt 131, and a material transfer robot is arranged between the third conveyor belt 131 and the frame forming mechanism 132, and the material transfer robot cooperates to transfer the material (including facial tissue and cardboard, which have been wrapped) on the third conveyor belt 131 to the frame forming mechanism 132 for frame forming. The frame forming mechanism 132 is a mature technology and will not be described in detail. For example, the material transfer robot includes a transverse lifting air nozzle, which can perform lifting and transverse movement, and uses the transverse lifting air nozzle to suck the material and cooperate with the action to transfer the material. In addition, the paper supply lifting platform 10 can use a unified lifting support plate to lift and supply facial paper (such as facial paper side by side on the left and right); or as in the embodiment, the paper supply lifting platform 10 can also include a left lifting facial paper support plate 101 and a right lifting facial paper support plate 102, respectively supplying facial paper side by side on the left and right, to avoid the problem that the stacking height of the left and right facial paper is not uniform and affects the feeding, wherein the left lifting facial paper support plate 101 and the right lifting facial paper support plate 102 are respectively equipped with their own lifting driving devices (such as motors, etc.). Among them, the paper feeding device 11 includes a left feeder paper feeding component 111 and a right feeder paper feeding component 112, and the feeder paper feeding is a mature technology. The left feeder paper feeding component 111 is arranged between the left lifting facial paper support plate 101 and the gluing device 12, and the right feeder paper feeding component 112 is arranged between the right lifting facial paper support plate 102 and the gluing device 12. The gluing device 12 includes a gluing roller 121, which is a mature technology.

[0061] The cardboard and face paper positioning and pasting machine 14 will adopt a common positioning machine (or cover machine) in the production equipment of leather shells or paper boxes. For example, the cardboard and face paper positioning and pasting machine 14 includes a cardboard feeding table 141 and a positioning and pasting robot. The cardboard and face paper positioning and pasting machine 14 is connected with the first conveyor belt 15 so that the cardboard and face paper positioning and pasting machine 14 can transfer the long cardboard to the face paper of the first conveyor belt 15 for pasting. The cardboard feeding table 141 generally includes a cardboard material warehouse, a lateral push component, a support rail and a cardboard pusher.
