Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automatic carton sealing device that improves efficiency. Background Technology

[0002] An automatic carton sealing device refers to a mechanical device that automatically seals carton boxes. The automatic tape bonding mechanism is installed above the production line. During operation, the carton is placed on the production line and conveyed to the area below the automatic tape bonding mechanism by a conveyor belt. The automatic tape bonding mechanism outputs tape to the carton for bonding and cutting, thus achieving the function of bonding and cutting tape at the opening of the carton without manual intervention, thereby improving the efficiency of carton sealing.

[0003] However, most automatic carton sealing devices on the market do not press and close the top opening of the carton during the sealing process. This means that when the cardboard at the opening of the carton is spread out, it will affect the adhesion of the tape to the carton by the automatic adhesive mechanism, thus affecting the automatic sealing efficiency of the carton. Utility Model Content

[0004] Therefore, there is a need to provide an efficient automatic carton sealing device to solve the problem that the lack of a pressing and closing operation on the top opening of the carton during the sealing process affects the automatic sealing of the carton.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an efficient automatic carton sealing device, comprising a base, a first motor, a conveyor belt, a sealing frame, an automatic tape bonding machine, a first electric telescopic rod, and a pressing plate. The first motor and the conveyor belt are mounted on the base and electrically connected. The first motor drives the conveyor belt. The sealing frame is mounted on top of the base, and the automatic tape bonding machine is mounted on the upper part of the sealing frame and above the conveyor belt. The first electric telescopic rod is mounted on one side of the sealing frame and above the conveyor belt. The output end of the first electric telescopic rod is connected to the pressing plate and faces the conveyor belt. The pressing plate is positioned higher than the height at which the carton is placed on the conveyor belt. The distance between the automatic tape bonding machine and the pressing plate is less than the length of the carton along the conveyor belt.

[0006] Furthermore, it also includes a first connecting plate disposed on one side of the packaging frame; the first electric telescopic rod is disposed on one side of the packaging frame through connection with the first connecting plate.

[0007] Furthermore, it also includes a clamping block, which is disposed below the clamping plate and connected to the clamping plate.

[0008] Furthermore, it also includes at least one first elastic element, one end of which is connected to the bottom of the pressure plate, and the other end of which is connected to the upper part of the pressure block, so that the pressure block is connected to the pressure plate through the first elastic element.

[0009] Furthermore, a first buffer groove is provided at the bottom of the pressing plate, and one end of the first elastic member is connected to the inner top wall of the first buffer groove, thereby connecting with the bottom of the pressing plate.

[0010] Furthermore, it also includes at least one first roller, which is disposed at the bottom of the pressing block and rotatably connected to the pressing block; the rotation direction of the first roller is adapted to the conveying direction of the conveyor belt.

[0011] Furthermore, it also includes a number of first rods corresponding to the first roller, which are disposed at the bottom of the pressing block; the first roller is sleeved on the first rod and forms a rotatable connection.

[0012] Furthermore, a first groove is provided at the bottom of the clamping block, and the two ends of the first rod are disposed on the inner sidewall of the first groove.

[0013] Furthermore, it also includes two second electric telescopic rods, which are arranged on both sides of the base with the conveyor belt as the center; the output end of the second electric telescopic rod is connected to a limit plate and faces the conveyor belt.

[0014] Furthermore, it also includes two second connecting plates, which are arranged on both sides of the base with the conveyor belt as the center; the second electric telescopic rod is set on the base through the connection with the second connecting plates.

[0015] The technical effects achieved by the above technical solution, which differ from existing technologies, are as follows:

[0016] By placing the first electric telescopic rod on one side of the packaging rack and above the conveyor belt; the output end of the first electric telescopic rod is connected to the pressing plate and faces the conveyor belt; the pressing plate is positioned higher than the height of the carton when it is placed on the conveyor belt; therefore, when the carton is placed on the conveyor belt and conveyed to below the pressing plate, the first electric telescopic rod automatically starts, driving the pressing plate downwards through its output end, thereby pressing and closing the opening of the carton; since the distance between the automatic tape bonding machine and the pressing plate is less than the length of the carton along the conveyor belt, the carton remains in an open and closed state, and is automatically bonded by the automatic tape bonding machine; thus ensuring the automatic sealing of the carton and improving the efficiency of automatic carton sealing.

[0044] Please see Figures 1-7 This utility model provides an efficient automatic carton sealing device, including a base 1, a first motor 2, a conveyor belt 3, a sealing frame 4, an automatic tape bonding machine 5, a first electric telescopic rod 6, and a pressing plate 7. The first motor 2 and the conveyor belt 3 are mounted on the base 1 and are electrically connected. The first motor 2 drives the conveyor belt. The sealing frame 4 is mounted on top of the base 1. The automatic tape bonding machine 5 is mounted on the upper part of the sealing frame 4 and above the conveyor belt. The first electric telescopic rod 6 is mounted on one side of the sealing frame 4 and above the conveyor belt 3. The output end of the first electric telescopic rod 6 is connected to the pressing plate 7 and faces the conveyor belt 3. The pressing plate 7 is positioned higher than the height of the carton when it is placed on the conveyor belt 3. The distance between the automatic tape bonding machine 5 and the pressing plate 7 is less than the length of the carton along the conveyor belt 3.

[0045] The basic principle is as follows: the first electric telescopic rod 6 is set on one side of the packaging frame 4 and above the conveyor belt 3; the output end of the first electric telescopic rod 6 is connected to the pressing plate 7 and faces the conveyor belt 3; the position of the pressing plate 7 is higher than the height of the carton when it is placed on the conveyor belt 3; therefore, when the carton is placed on the conveyor belt 3 and conveyed to the area below the pressing plate 7, the first electric telescopic rod 6 is automatically activated, driving the pressing plate 7 downward through its output end, thereby pressing and closing the opening of the carton; since the distance between the automatic tape bonding machine 5 and the pressing plate 7 is less than the length of the carton along the direction of the conveyor belt 3, the carton remains in an open and closed state, and is automatically bonded by the automatic tape bonding machine 5; thus ensuring the automatic sealing of the carton and improving the efficiency of automatic carton sealing.

[0046] Preferably, it further includes a control mechanism disposed on the base 1. The control mechanism is electrically connected to the first motor 2 and the first electric telescopic rod 6, and is used to control the operation of the first motor 2 and the first electric telescopic rod 6; the control mechanism is electrically connected to the second electric telescopic rod 8, and is used to control the operation; the control mechanism is electrically connected to the third electric telescopic motor 64, and is used to control the operation. In specific operation, the control mechanism controls the operation of the first motor 2, causing the conveyor belt 3 to transport the carton. When the carton is transported to the limiting area of ​​the limiting plate 9, the control mechanism controls the second electric telescopic rod 8 to extend and retract, driving the limiting plate 9 to limit the carton and keep it centered on the conveyor belt 3 to prevent skewing. At the same time, when the carton is transported to the bottom of the pressing plate 7, the control mechanism controls the first electric telescopic rod 6 to extend and retract, driving the pressing plate 7 to press and close the carton opening. The carton continues to be transported to the automatic tape bonding machine 5 while the opening is closed, where the first tape 50 is bonded. When the tail of the carton is transported to the bottom of the blade 65, the control mechanism controls the third electric telescopic motor 64 to extend and retract, driving the blade 65 to cut the first tape 50 at the tail of the carton.

[0047] In some embodiments, a first connecting plate 71 is also included, disposed on one side of the packaging frame 4; the first electric telescopic rod 6 is disposed on one side of the packaging frame 4 through connection with the first connecting plate 71. By setting this structure, it is easier to arrange the setting position of the first electric telescopic rod 6 more flexibly.

[0048] In some embodiments, a clamping block 73 is also included, disposed below and connected to the clamping plate 7. This structural arrangement prevents the clamping plate 7 from directly contacting the carton, thus avoiding wear and extending its service life. Furthermore, the size of the clamping block 73 can be adjusted to fit the opening size of the carton without needing to adjust the size of the clamping plate 7, providing greater flexibility. Specifically, the "connection" here can be a detachable connection, a fastening connection, an indirect connection, etc.

[0049] In some embodiments, at least one first elastic element 72 is further included. One end of the first elastic element 72 is connected to the bottom of the pressing plate 7, and the other end of the first elastic element 72 is connected to the upper part of the pressing block 73, so that the pressing block 73 is connected to the pressing plate 7 through the first elastic element 72. By setting this structure, a cushioning effect is provided during the pressing and closing process of the opening of the carton, reducing damage to the carton.

[0050] In some embodiments, a first buffer groove 77 is provided at the bottom of the pressing plate 7, and one end of the first elastic member 72 is connected to the inner top wall of the first buffer groove 77, thereby connecting to the bottom of the pressing plate 7. By placing the first elastic member 72 inside the first buffer groove 77, it helps to protect the first elastic member 72 to a certain extent.

[0051] Preferably, the outer wall of the pressing block 73 is slidably sleeved with the inner wall of the first buffer groove 77. Since the pressing block 73 will generate friction with the opening of the carton during the pressing process, it may cause the pressing block 73 to deviate. This setting restricts the pressing block 73 to slide within the first buffer groove 77, which helps the pressing block 73 to be more stable and not deviate.

[0052] Preferably, there are four first elastic elements 72, which are distributed at the bottom of the pressure plate 7. This arrangement helps to distribute the force.

[0053] Optionally, the first elastic element can be a helical spring, a rubber spring, etc.

[0054] In some embodiments, at least one first roller 74 is further included, disposed at the bottom of the pressing block 73 and rotatably connected to the pressing block 73; the rotation direction of the first roller 74 is adapted to the conveying direction of the conveyor belt 3. Since the first electric telescopic rod 6 inevitably generates frictional force with the conveying direction of the conveyor belt 3 when it drives the pressing plate 7 and the pressing block 73 to press and close the opening of the carton conveyed by the conveyor belt 3, which hinders the conveying of the carton to a certain extent, the first roller 74 is provided so that it rotates under the action of frictional force, thereby reducing the resistance to the conveying of the carton.

[0055] Specifically, the first roller 74 is horizontally positioned and when mapped onto the conveyor belt 3, it is perpendicular to the conveying direction of the conveyor belt 3. This makes it easier to rotate under the action of friction, thereby reducing the resistance to the conveying of the carton.

[0056] In some embodiments, a number of first rods 75 corresponding to the first roller 74 are also included, disposed at the bottom of the pressing block 73; the first roller 74 is sleeved on the first rods 75 and forms a rotatable connection. That is, the first roller 74 is rotatably connected to the pressing block 73 through the rotatable connection formed by the first rods 75.

[0057] In some embodiments, the bottom of the clamping block 73 is provided with a first groove 76, and the two ends of the first rod 75 are disposed on the inner sidewall of the first groove 76. This arrangement helps to protect the first rod 75 and the first roller 74 to a certain extent; it also allows the first roller 74 to form a rotatable connection with the clamping block 73.

[0058] Preferably, the body of the first roller 74 protrudes from the opening of the first groove 76. Compared to when the body of the first roller 74 does not protrude from the opening of the first groove 76, this arrangement helps to ensure contact between the first roller 74 and the opening of the carton, thereby reducing the frictional force when friction is generated by rotating the first roller 74, thus reducing the resistance to the carton conveying.

[0059] Preferably, there are thirteen first rollers 74, which are distributed at the bottom of the pressing block 73. This arrangement helps to ensure that more first rollers 74 fully contact the carton opening during the pressing and closing process of the pressing block 73, thereby dispersing the force exerted on the carton opening.

[0060] In some embodiments, two second electric telescopic rods 8 are also included, positioned on both sides of the base 1 with the conveyor belt 3 as the center. The output ends of the second electric telescopic rods 8 are connected to limit plates 9 and face the conveyor belt 3. When the conveyor belt 3 transports cartons, some cartons are not transported along the center line, resulting in a skewed situation. This can affect the pressing and closing of the carton opening; that is, one side of the carton opening may be pressed, while the other side is not. When adhesive tape is continued to be delivered, misaligned tape adhesion can also occur. With this arrangement, when a carton is transported, the two second electric telescopic rods 8 automatically activate, pushing the limit plates 9 forward, thereby limiting the carton to the center of the conveyor belt 3, eliminating the skewed state, thus facilitating the pressing and closing of the carton opening, and consequently aiding in the adhesive tape adhesion of the carton opening.

[0061] In some embodiments, two second connecting plates 91 are also included, arranged on both sides of the base 1 with the conveyor belt 3 as the center; the second electric telescopic rod 8 is mounted on the base 1 through connection with the second connecting plates 91. This arrangement allows for more flexible placement of the second electric telescopic rod 8.

[0062] Preferably, the two second connecting plates 91 are symmetrically arranged on both sides of the base 1 with the conveyor belt 3 as the center. This arrangement makes the limiting force of the second electric telescopic rod 8 on the carton more uniform when it is started; moreover, the symmetrical arrangement is also more aesthetically pleasing.

[0063] Preferably, the device further includes at least one second elastic member 92 and a limiting block 93. One end of the second elastic member 92 is connected to the side of the limiting plate 9 facing the conveyor belt 3, and the other end of the second elastic member 92 is connected to the side of the limiting block 93 away from the conveyor belt 3. This arrangement helps to provide a buffering effect when limiting the carton.

[0064] Preferably, the limiting plate 9 has a second buffer groove 97 on the side facing the conveyor belt 3, and one end of the second elastic member 92 is connected to the bottom of the inner groove of the second buffer groove 97, thereby connecting with the side of the limiting plate 9 facing the conveyor belt 3. By placing the second elastic member 92 inside the second buffer groove 97, it helps to protect the second elastic member 92 to a certain extent.

[0065] Preferably, the outer wall of the limiting block 93 is slidably sleeved with the inner wall of the second buffer groove 97. Since the limiting block 93 generates friction on the carton during the process of limiting the carton, it also exerts a force on the limiting block 93, causing it to shift. This arrangement helps to make the limiting block 93 more stable and prevent it from shifting.

[0066] Preferably, there are four second elastic members 92, which are distributed on the side of the limiting plate 9 facing the conveyor belt 3. This arrangement helps to distribute the force and provides cushioning more effectively.

[0067] Optionally, the second elastic element can be a helical spring, a rubber spring, etc.

[0068] Preferably, it further includes at least one second roller 94, which is disposed on the side of the limiting block 93 facing the conveyor belt 3 and is rotatably connected to the pressing block 73; the rotation direction of the second roller 94 is adapted to the conveying direction of the conveyor belt 3. Since the second electric telescopic rod 8 inevitably generates frictional force with the conveying direction of the conveyor belt 3 when it drives the limiting plate 9 and the limiting block 93 to limit the carton conveyed by the conveyor belt 3, which hinders the conveying of the carton to a certain extent, the second roller 94 is provided. The second roller 94 rotates under the action of friction, thereby reducing the resistance to the conveying of the carton.

[0069] Specifically, the body of the second roller 94 is vertically arranged and perpendicular to the conveying direction of the conveyor belt 3. This makes it easier to rotate when subjected to friction, thereby reducing the resistance to the conveying of the carton.

[0070] Preferably, the system further includes a number of second rods 95 corresponding to the number of second rollers 94, disposed on the side of the limiting block 93 facing the conveyor belt 3; the second rollers 94 are sleeved on the second rods 95, thereby forming a rotatable connection with the limiting block 93. That is, the second rollers 94 form a rotatable connection with the limiting block 93 through the rotatable connection formed by the second rods 95.

[0071] Preferably, the limiting block 93 has a second groove 96 on the side facing the conveyor belt 3, and the two ends of the second rod 95 are disposed on the inner sidewall of the second groove 96, so that the second roller 94 is rotatably connected to the limiting block 93. This arrangement helps to protect the second rod 95 and the second roller 94 to a certain extent; it also allows the second roller 94 to be rotatably connected to the limiting block 93.

[0072] Preferably, the body of the second roller 94 protrudes from the opening of the second groove 96. Compared to when the body of the second roller 94 does not protrude from the opening of the second groove 96, this arrangement helps to ensure contact between the second roller 94 and the carton, thereby reducing friction when friction is generated by rotating the second roller 94, thus reducing resistance to the carton conveying.

[0073] Preferably, there are thirteen second rollers 94, which are distributed on the side of the limiting block 93 facing the conveyor belt 3. With this arrangement, when the limiting block 93 limits the carton, more second rollers 94 are used to contact the carton, giving full play to the role of the rotation of the second rollers 94 in reducing frictional resistance.

[0074] Preferably, the two second electric telescopic rods 8 are symmetrically arranged on both sides of the base 1 with the conveyor belt 3 as the center. This arrangement makes the limiting force of the second electric telescopic rods 8 on the carton more uniform when started; moreover, the symmetrical arrangement is also more aesthetically pleasing.

[0075] Preferably, one side of the pressing plate 7 is close to or slidably connected to one side of the packaging frame 4. Combined with the previously mentioned "the distance between the automatic tape bonding machine 5 and the pressing plate 7 is less than the length of the carton along the conveyor belt 3," this arrangement helps to further reduce the distance between the automatic tape bonding machine 5 and the pressing plate 7. This allows the automatic tape bonding machine 5 to simultaneously apply tape to the carton while the pressing plate 7 is pressing and closing the carton opening, preventing the carton opening from reopening after pressing and closing, and improving the carton packaging efficiency.

[0076] Preferably, the automatic tape bonding machine 5 is mounted on the packaging frame 4 and is positioned close to the pressure plate 7. Combined with the previously mentioned distance between the automatic tape bonding machine 5 and the pressure plate 7 being less than the length of the carton along the conveyor belt 3, this arrangement helps to further reduce the distance between the automatic tape bonding machine 5 and the pressure plate 7. This allows the automatic tape bonding machine 5 to simultaneously apply tape to the carton while the pressure plate 7 is pressing and closing the carton opening, preventing the carton opening from reopening after pressing and closing, and improving the packaging efficiency of the carton.

[0077] Preferably, it also includes a plurality of support seats 11, which are distributed in the lower part of the base 1 to provide support for the base 1.

[0078] Preferably, the automatic tape bonding machine 5 includes a support assembly, a tape pressure roller assembly mounted on the support assembly, a knife holder, a blade 65, a third electric telescopic motor 64, a tape fixing roller 52, and a fixing roller bracket 53; the support assembly is mounted on the packaging frame 4 and is located above the conveyor belt 3; the fixing roller bracket 53 is mounted on the support assembly, and the tape fixing roller 52 is mounted on the top of the fixing roller bracket 53; the blade 65 is fixed on the knife holder and is located above the conveyor belt 3, and the blade 65 is inclined in the opposite direction to the conveyor belt 3; the third electric telescopic motor 64 is mounted on the support assembly, and the knife holder is mounted on its output end; the tape pressure roller assembly includes an upper tape pressure roller 54, an upper pressure roller bracket 55, a middle tape support roller, a front pressure roller connecting rod 57, a front tape pressure roller 58, a rear pressure roller connecting rod 59, and a rear tape pressure roller 60, and the upper pressure roller bracket 55... The lower rotating connection is mounted on the support assembly, and the upper tape pressure roller 54 is mounted on its top. The middle tape support roller is mounted on the support assembly for supporting and conveying the tape. The front pressure roller connecting rod 57 is mounted on the support assembly via a first hinge shaft 61 and forms a rotating connection with the support assembly, and the front tape pressure roller 58 is fixedly connected to its bottom. The rear pressure roller connecting rod 59 is mounted on the support assembly via a second hinge shaft 62 and forms a rotating connection with the support assembly, and the rear tape pressure roller 60 is fixedly connected to its bottom. It also includes a linkage connecting rod 63, whose two ends are hinged to the front pressure roller connecting rod 57 and the rear pressure roller connecting rod 59, respectively. It also includes a first tension spring 67, which is mounted between the fixed roller support 53 and the upper pressure roller support 55 for pressing the upper tape pressure roller 54 against the first tape 50 on the tape fixed roller 52. The sealing frame has a tape through hole 40 for conveying the first tape 50.

[0079] The basic principle of the automatic tape bonding machine 5 is as follows: A first tape 50 is mounted on a tape fixing roller 52. The tape is pulled out from the bottom of the tape fixing roller 52, passes over the upper tape pressure roller 54, passes through the tape through-hole 40, and continues to pass over the middle tape support roller, thus hanging down naturally (with the adhesive side of the tape facing outwards and not in contact with the tape pressure roller assembly). It is positioned in front of the carton conveyor. When the carton arrives, it first contacts the adhesive side of the tape and then continues to touch the rear tape pressure roller 60. The rear pressure roller connecting rod 59 is subjected to… The force drives the rear tape pressure roller 60 to rotate upwards, and the carton continues to be conveyed, so that the tape adheres to the opening of the carton. When the tape at the tail of the carton is just conveyed to the bottom of the blade 65, the third electric telescopic motor 64 automatically starts to telescopically move, thereby driving the blade 65 on the blade holder to telescopically move, thereby cutting the tape. At the same time, the carton continues to be conveyed and touches the front tape pressure roller 58. The front pressure roller connecting rod 57 is forced to rotate upwards, so that the front tape pressure roller 58 presses the carton firmly, further ensuring the sealing and adhesion of the carton.

[0080] Preferably, the bracket assembly includes two first mounting plates 51, each with a plurality of screw holes 66. The two first mounting plates 51 are threadedly connected to nuts by screws passing through the screw holes 66, thereby forming a bracket assembly. The fixed wheel bracket 53, the upper pressure wheel bracket 55, the middle tape pressure wheel 56, the front pressure wheel connecting rod 57, the rear pressure wheel connecting rod 59, the rear tape pressure wheel 60, the linkage connecting rod 63, and the third electric telescopic motor 64 are all disposed between the two first mounting plates 51.

[0081] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
