Description

Technical Field

[0001] The utility model relates to the technical field of carton unpacking, in particular to an unpacking and forming mechanism. Background Art

[0002] With the progress of technology, mechanical production has become more and more common, and more and more machines have replaced manual operations. Especially in the production line, mechanized production not only saves manpower and material resources, but also greatly improves work efficiency. The products to be produced need to be packaged, and the packaging cartons used for product packaging are in the form of sheet embryos when leaving the factory, and need to be batch-fed into an unpacking machine and unpacked before they can be used.

[0003] The function of the unpacking and forming machine is to open a flat carton into a three-dimensional state, and then the carton in the three-dimensional state continues to complete the folding of the lower lid and seal the lower lid. The opening on the upper part of the carton unpacked by the unpacking and forming machine is used to place items, and then the lid can be sealed by a sealing machine.

[0004] The existing unpacking and forming machines cannot be applied to the unpacking work of corrugated cartons of different specifications at the same time. The unpacking efficiency is low, and the universality is not strong, which affects the production efficiency. Therefore, an unpacking and forming mechanism is needed to solve the above problems. Content of the Utility Model

[0005] In order to overcome the above disadvantages, the purpose of the utility model is to provide an unpacking and forming mechanism, which is applicable to the unpacking and forming of corrugated cartons of different specifications, and improves the unpacking and forming efficiency and applicability of the cartons.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an unpacking and forming mechanism, including a frame, an unpacking mechanism and a bottom-sealing mechanism arranged in sequence along the length direction of the frame; the unpacking mechanism includes a carton moving support plate and push plate mechanisms on both sides thereof, the bottom-sealing mechanism includes a tape feeding assembly and two mounting plates arranged oppositely for installing it, the tape feeding assembly includes a tape roll, and one end of the tape on the tape roll moves along a guide roller to the side of the mounting plate close to the unpacking mechanism.

[0007] Further, the push plate mechanism includes a push plate driving member, and a bending plate is connected to the driving end of each push plate driving member. The push plate driving member drives the bending plate to move towards the direction close to the long side of the bottom of the carton, so as to bend the long side of the bottom of the carton to be parallel to the carton moving support plate, and complete the bending and forming of the long side of the bottom of the carton.

[0008] Further, one end of the cardboard box moving support plate away from the bottom sealing mechanism is inclined upward and is arranged in an arc structure. The bending plate includes a vertically arranged abutting surface connected to the driving end of the push plate driving member and a placing plane parallel to the horizontal plane. The upper surface of the abutting surface is connected to the placing plane through an inclined push plate surface. The arc structure is arranged such that when the cardboard box moves along the cardboard box moving support plate, the bottom short side of the side of the cardboard box away from the bottom sealing mechanism can be bent along this structure to abut against the upper surface of the cardboard box moving support plate, realizing the automatic bending of the two bottom short sides of the cardboard box; the abutting surface is connected to the driving end of the push plate driving member, so that when the push plate driving member works, it can drive the entire bending plate to move back and forth, and further realize the automatic bending of the two bottom long sides of the cardboard box.

[0009] Further, the bottom sealing mechanism further includes a connecting rod assembly. The connecting rod assembly includes a left connecting rod and a right connecting rod hinged to the mounting plate through a connecting shaft. The bottom parts of the left connecting rod and the right connecting rod are respectively hinged to both ends of the connecting rod bracket, and a pressing wheel is respectively arranged at the top. When the pressing wheel on the left connecting rod rotates away from the box opening mechanism with the connecting shaft as the fulcrum, the connecting rod bracket can drive the pressing wheel on the right connecting rod to rotate synchronously towards the direction of the left connecting rod.

[0010] One end of the tape on the tape roll for tape feeding is located on the left side of the left connecting rod. The cardboard box after bottom bending moves from the left side to the right side for feeding. The tape is first attached to the bottom of the right side of the cardboard box. As the cardboard box moves, a force is applied to the left connecting rod to make it rotate with the connecting shaft as the fulcrum. Under the action of the connecting rod bracket, the right connecting rod rotates synchronously towards the left connecting rod until the top of the pressing wheel on it contacts the bottom of the cardboard box moving onto it. The pressing wheel rolls on the surface of the tape after the tape is automatically adhered to the bottom of the cardboard box, so that the tape is more firmly adhered to the surface of the cardboard box, ensuring the bottom sealing efficiency of the cardboard box.

[0011] Further, a limit stop rod and a stop block are respectively arranged on the mounting plate on the upper and lower sides of the connecting rod bracket. The limit stop rod horizontally connects two opposite mounting plates. A limit block corresponding to the position of the stop block protrudes from the lower surface of the connecting rod bracket. The limit block is located on the left side of the stop block, and a limit groove matching the stop block is opened on the side of the limit block close to the stop block. After the cardboard box disengages from the right connecting rod, the pressure applied to the right connecting rod disappears, and the left connecting rod and the right connecting rod are reset under the action of the connecting rod bracket. The setting of the limit stop rod and the stop block can limit the rotation angle of the left connecting rod and the right connecting rod with the connecting shaft as the fulcrum, enabling them to accurately reset, and at the same time ensuring the efficiency of the pressing wheel assisting in tape sealing of the cardboard box.

[0012] Further, a tape guiding assembly is provided on the left connecting rod. The tape guiding assembly includes a guiding frame connected to the left connecting rod and a connecting baffle. At both ends of the guiding frame in the length direction, a U-shaped baffle is respectively provided. The openings of the two U-shaped baffles are arranged opposite to each other and form a U-shaped groove for the connecting baffle to be placed together with the guiding frame. At both ends of the connecting baffle in the length direction, it is threadedly connected to one side of a U-shaped baffle close to the guiding frame. A connecting ear extends from the middle of the connecting guide plate towards the direction of the case opening mechanism. The adhesive surface of the tape faces the direction of the case opening mechanism, and the top of the guiding frame is inclined at an angle towards the direction of the case opening mechanism, ensuring that the top of the tape adheres to the bottom side of the carton first, guaranteeing the stability of subsequent tape bottom sealing.

[0013] Further, a number of tension rollers parallel to the guiding rollers are also provided between the two mounting plates. By providing the tension rollers, it is ensured that the tape is always in a tensioned state during feeding, preventing the tape from sticking together and affecting the bottom sealing of the carton.

[0014] Further, the carton moving support plate is connected to the protective housing on the bottom sealing mechanism through a connecting plate, and the upper surface of the carton moving support plate and the upper surface of the protective housing are on the same horizontal plane. At least one side of the connecting plate in the length direction is provided with an auxiliary connecting rod.

[0015] Advantages of the present utility model:

[0016] In the present utility model, the case opening mechanism and the bottom sealing mechanism cooperate with each other. The carton moving support plate on the case opening mechanism is used to support the carton placed thereon. Two relatively arranged push plate driving members push the bending plates connected to their driving ends to expand and contract, thereby being able to adjust the distance between the two bending plates. When the carton is bent and formed, it is located between the two bending plates. The bottom sealing mechanism can shape the bottom of the bent carton. Therefore, by adjusting the telescopic length of the driving end of the push plate driving member, the device can be adapted to corrugated cartons of different specifications for case opening and forming, improving the efficiency and applicability of carton case opening and forming.

Specific embodiments

[0025] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0026] See the appendix Figures 1 to 7As shown in the figure, an unpacking and forming mechanism in this embodiment includes a frame 1, an unpacking mechanism 2 and a bottom-sealing mechanism 3 arranged in sequence along the length direction of the frame 1. The unpacking mechanism 2 includes a carton moving support plate 21 and push plate mechanisms 24 on both sides thereof. The bottom-sealing mechanism 3 includes a tape feeding assembly 36 and two opposite mounting plates 32 for mounting it. The tape feeding assembly 36 includes a tape roll 362, and one end of the tape on the tape roll 362 moves along a guide roller 363 to the side of the mounting plate 32 close to the unpacking mechanism 2. The unpacking mechanism 2 can automatically fold the four sides of the bottom of the three-dimensional carton towards the inside of the carton until they are parallel to the surface of the carton moving support plate 21, completing the preliminary forming of the bottom of the carton. The external driving mechanism can drive the carton to move along the length direction of the carton moving support plate 21 and move the carton with a preliminarily formed bottom to the bottom-sealing mechanism 3. The tape roll 362 that automatically feeds the tape seals the bottom of the carton, shapes the carton bent into a box shape, and then realizes the complete forming of the carton. The mutual cooperation of the unpacking mechanism 2 and the bottom-sealing mechanism 3 is applicable to the unpacking and forming of corrugated cartons of different specifications, improving the efficiency and applicability of carton unpacking and forming.

[0027] The push plate mechanism 24 includes a push plate driving member, and a bending plate 25 is connected to the driving end of each push plate driving member. The push plate driving member drives the bending plate 25 to move towards the direction close to the long side of the bottom of the carton, so as to bend the long side of the bottom of the carton until it is parallel to the carton moving support plate 21, completing the bending and forming of the long side of the bottom of the carton.

[0028] The distance between the two oppositely arranged bending plates 25 can be adjusted by the push plate driving member, and the long sides on both sides of the bottom of the carton are located between the two bending plates 25. Therefore, by adjusting the push plate driving member, the unpacking mechanism 2 can be made applicable to the unpacking and forming of corrugated cartons of different specifications.

[0029] In some embodiments, the push plate driving member is a driving cylinder, and the push plate cylinder and the bending plate 25 are symmetrically arranged along the length direction of the carton moving support plate 21, and can push the long side of the bottom of the carton from both sides along the length direction of the carton moving support plate 21 where the carton is placed, so that the long side of the bottom of the carton bends towards the inside of the carton, completing the automatic forming of the long side of the bottom of the carton.

[0030] It should be noted that the push plate driving member is not limited to only being a push cylinder, and can also be a push screw rod or other known mechanical structures that can push the bending plate 25 to approach horizontally towards the carton.

[0031] One end of the carton moving support plate 21 away from the bottom sealing mechanism 3 is inclined upward and is provided with an arc structure 22. The bending plate 25 includes a vertically arranged abutting surface 253 connected to the driving end of the push plate driving member and a placing plane 251 parallel to the horizontal plane. The upper surface of the abutting surface 253 is connected to the placing plane 251 through an inclined push plate surface 252. The setting of the arc structure 22 enables the short side at the bottom of the side of the carton away from the bottom sealing mechanism 3 to be bent along this structure to abut against the upper surface of the carton moving support plate 21 when the carton moves along the carton moving support plate 21, realizing the automatic bending of the two short sides at the bottom of the carton; the abutting surface 253 is connected to the driving end of the push plate driving member, so that when the push plate driving member works, it can drive the entire bending plate 25 to move back and forth, and further realize the automatic bending of the two long sides at the bottom of the carton.

[0032] Specifically, the push plate surface 252 is inclined in a direction away from the carton moving support plate 21. When bending the long side at the bottom of the carton, the inclined push plate surface 252 contacts it first, and bends the long side toward the inside of the carton until the long side is horizontally placed on the placing plane 251, completing the forming of the entire bottom of the carton.

[0033] The bottom sealing mechanism 3 further includes a connecting rod assembly 34. The connecting rod assembly 34 includes a left connecting rod 342 and a right connecting rod 343 hinged to the mounting plate 32 through a connecting shaft 35. The bottom parts of the left connecting rod 342 and the right connecting rod 343 are respectively hinged to both ends of the connecting rod bracket 341, and a pressing wheel 344 is respectively arranged at the top. When the pressing wheel 344 on the left connecting rod 342 rotates in a direction away from the box opening mechanism 2 with the connecting shaft 35 as the fulcrum, the connecting rod bracket 341 can drive the pressing wheel 344 on the right connecting rod 343 to rotate synchronously in the direction of the left connecting rod 342.

[0034] One end of the tape on the tape roll 362 for tape feeding is located on the left side of the left connecting rod 342. The carton after the bottom is bent moves from the left side to the right side of the left connecting rod 342 for feeding. The tape is first attached to the bottom of the right side of the carton. As the carton moves, a force is applied to the left connecting rod 342 to make it rotate with the connecting shaft 35 as the fulcrum. Under the action of the connecting rod bracket 341, the right connecting rod 343 rotates synchronously in the direction of the left connecting rod 342 until the top of the pressing wheel 344 on it contacts the bottom of the carton moving onto it. The pressing wheel 344 plays a role in rolling the surface of the tape after the tape is automatically adhered to the bottom of the carton, so that the tape is more firmly adhered to the surface of the carton, ensuring the bottom sealing efficiency of the carton.

[0035] It should be noted that the ends of the left connecting rod 342 and the right connecting rod 343 connecting the pressing wheels 344 are higher than the height of the horizontal movement of the carton in the non-working state, so as to ensure that when the carton moves from left to right, pressure can be applied to the left connecting rod 342 from its left side.

[0036] It further includes a fixing plate 31 arranged along the length direction of the frame 1 for fixedly mounting the mounting plate 32. Specifically, the mounting plate 32 is connected to the fixing plate 31 through a connecting rod, and a connecting rod bracket for supporting the connecting rod is arranged on the fixing plate 31.

[0037] On the mounting plate 32, a limiting stop rod and a stop block 345 are respectively arranged on the upper and lower sides of the connecting rod bracket 341. The limiting stop rod 39 horizontally connects two oppositely arranged mounting plates 32. A limiting block corresponding to the position of the stop block 345 protrudes from the lower surface of the connecting rod bracket. The limiting block is located on the left side of the stop block 345, and a limiting groove matching the stop block 345 is opened on the side of the limiting block close to the stop block 345. After the carton disengages from the right connecting rod 343, the pressure applied to the right connecting rod 343 disappears, and the left connecting rod 342 and the right connecting rod 343 are reset under the action of the connecting rod bracket 341. The arrangement of the limiting stop rod and the stop block 345 can limit the rotation angle of the left connecting rod 342 and the right connecting rod 343 with the connecting shaft 35 as the fulcrum, enabling accurate reset, and at the same time ensuring the efficiency of the pressure wheel 344 assisting in sealing the carton with tape.

[0038] In some embodiments, the limiting groove is arc-shaped, and the stop block 345 is a horizontally arranged cylinder.

[0039] A tape guiding assembly 38 is arranged on the left connecting rod 342. The tape guiding assembly 38 includes a guiding frame 381 connected to the left connecting rod 342 and a connecting baffle 382. At both ends of the length direction of the guiding frame 381, a U-shaped baffle 384 is respectively arranged. The openings of the two U-shaped baffles 384 are oppositely arranged and form a U-shaped groove for the connecting baffle 382 to be placed with the guiding frame 381. At both ends of the length direction of the connecting baffle 382, they are respectively threadedly connected to one side of a U-shaped baffle 384 close to the guiding frame 381. A connecting ear 383 extends from the middle of the connecting guide plate towards the direction of the box opening mechanism 2. The adhesive surface of the tape faces the direction of the box opening mechanism 2, and the top of the guiding frame 381 is inclined at an angle towards the direction of the box opening mechanism 2 to ensure that the top of the tape adheres to the bottom side of the carton first, ensuring the stability of subsequent tape bottom sealing. There is no interference and no contact between the connecting ear 383 and the U-shaped baffle 384, and the connecting ear 383 at least partially protrudes from the U-shaped baffle 384. By setting the connecting ear 383, the tape is limited to move within the groove formed by the connecting baffle 382 and the U-shaped groove. The connecting ear 383 contacts the non-adhesive side of the tape, effectively preventing the tape from slipping out of the tape guiding assembly 38 and ensuring the efficiency of tape bottom sealing.

[0040] A number of tension rollers 364 parallel to the guide roller 363 are also arranged between the two mounting plates 32. By setting the tension rollers 364, it is ensured that the tape is always in a tensioned state during feeding, avoiding the tape sticking together and affecting the bottom sealing of the carton.

[0041] The carton moving support plate 21 is connected to the protective shell 5 on the bottom sealing mechanism 3 through the connecting plate 4, and the upper surface of the carton moving support plate 21 is on the same horizontal plane as the upper surface of the protective shell 5, and at least one side of the connecting plate 4 in the length direction is provided with an auxiliary connecting rod 37. The unpacking mechanism 2 and the bottom sealing mechanism 3 are connected by the connecting plate 4, and the upper surfaces are both located in the same plane, so that there is no gap between the two mechanisms, and the carton will not be interfered in the process of moving from the unpacking mechanism 2 to the bottom sealing mechanism 3, thereby improving the unpacking and bottom sealing efficiency of the carton. The setting of the auxiliary connecting rod 37 can assist the front and rear pressure wheels 344 to perform tape sealing.

[0042] The side of the carton moving support plate 21 that is not connected to the protective shell 5 is connected to the frame 1 through a plate bracket 23 .

[0043] The feeding shaft 361 is rotatably connected to the fixing plate 31 via the connecting plate 4 .

[0044] Working principle: When the box opening and forming mechanism is used, the external manipulator opens the flat carton into a three-dimensional state and moves it to the side of the carton moving support plate 21 with an arc structure 22. The three-dimensional state of the carton is as shown in the attached figure. Figure 1 As shown in the state of the carton in the figure, the robot tilts the carton toward the direction close to the bottom sealing mechanism 3, and gradually moves downward until it is placed on the carton moving support plate 21. During the tilting process, the short side of the carton close to the bottom sealing mechanism 3 is gradually bent toward the inside of the carton, and the other side is also folded toward the inside of the carton along the arc structure 22. At this point, the automatic folding of the two short sides of the bottom of the carton is completed, and the two short sides of the bottom of the carton are in contact with the surface of the carton moving support plate 21, while the two long sides of the bottom of the carton are parallel to the length direction of the carton moving support plate 21;

[0045] Then the external manipulator moves the carton along the carton moving support plate 21 to the push plate mechanism 24, and the push plate cylinder piston cylinder extends to push the bending plate 25 toward the long side of the carton, so that it is bent toward the inside of the carton until the bottom surface of the carton is pushed and abuts against the placement plane 251 on the bending plate 25. Finally, the external manipulator continues to work and moves the carton with the bottom bent along the carton moving support plate 21 to the bottom sealing mechanism 3 for bottom sealing.

[0046] The bent bottom of the carton abuts against the protective shell 5 on the bottom sealing mechanism 3. Under the movement of the external manipulator, the bottom of the carton on one side close to the bottom sealing mechanism 3 first contacts and adheres to the tape. As the carton continues to move, the tape can seal the bottom of the carton along the moving direction of the carton, completing the automatic bottom sealing and forming the carton.

[0047] During the movement of the cardboard box, the pressing wheel 344 on the left connecting rod 342 can be pushed to rotate with the connecting shaft 35 as the fulcrum, so that the pressing wheel 344 on the right connecting rod 343 rotates synchronously with the pressing wheel 344 on the left connecting rod 342 under the action of the connecting rod bracket 341 and the connecting shaft 35 until the surface of the pressing wheel 344 is located inside the protective housing 5. It should be noted that after the two pressing wheels 344 come into contact with the bottom surface of the cardboard box, they will remain in contact until they are completely separated from the cardboard box. By pressing the tape adhered to the bottom of the cardboard box with the pressing wheel 344, the adhesion between the tape and the bottom of the cardboard box is made more firm and fitting.

[0048] It should be noted that during the bottom sealing process, the external manipulator continuously moves the cardboard box.

[0049] The above embodiments are only for explaining the technical concept and features of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention.
