Description

Technical Field

[0001] The utility model relates to the technical field of case packers, and particularly relates to a case sealing mechanism of a case packer. Background Art

[0002] In the prior art, a carton includes a box body and folding pieces that can be folded relative to the box body. The folding pieces include a top cover and a bottom cover. When materials are assembled into the box body, the folding pieces folded onto the box body are fixed by glue or tape to prevent the materials in the carton from falling out. With the development of society, the existing carton loading realizes automated operation, and the automated cartons can perform glue dripping or tape sticking to fix the folding pieces. However, the existing case sealing mechanism only has one of the functions of glue dripping or tape sticking, so it cannot be flexibly switched and has limitations in use. Summary of the Invention

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a case sealing mechanism of a case packer, which can perform both glue dripping fixation and tape fixation, and has relatively strong practicability.

[0004] The utility model discloses a case sealing mechanism of a case packer, which includes a frame. A case sealing channel is arranged on the frame. A box pushing support for receiving and pushing a carton and a box pushing driving component for driving the box pushing support to move are arranged on the frame. A bottom cover folding structure and a top cover folding structure are sequentially arranged on both sides of the case sealing channel on the frame. When the box pushing support moves, it can drive the carton to pass through the bottom cover folding structure and the top cover folding structure in sequence. The bottom cover folding structure includes a bottom cover folding part I and a bottom cover folding part II arranged at intervals in the front-back direction. Both the bottom cover folding part I and the bottom cover folding part II have a first inclined guiding surface for guiding the folding of the bottom cover on the right side. Tongue pressing parts and tongue pressing driving parts for driving the tongue pressing parts to rotate are rotatably arranged on the frame at positions corresponding to the bottom cover folding part I and the bottom cover folding part II. The tongue pressing parts can rotate in and out of the case sealing channel to fold another bottom cover onto the box body. Two groups of top cover folding structures are arranged at intervals in the front-back direction. Each group of top cover folding structures includes a top cover folding part I and a top cover folding part II arranged at intervals in the up-down direction. Both the top cover folding part I and the top cover folding part II have a second inclined guiding surface for guiding the folding. It is characterized in that: A glue gun is also arranged on the frame at the position of the bottom cover folding structure. When the carton passes through the position of the glue gun, the outlet end of the glue gun corresponds to the top cover position. A tape assembly is arranged on the right side of each top cover folding structure, and a resisting part for restricting the reset after the top cover is folded is also arranged between the tape assembly and the top cover folding structure.

[0005] With the above technical solution, during use, the box-pushing drive assembly drives the box-pushing support to move, thereby pushing the cardboard box to the position of the sealing channel. At this time, the bottom cover folding member I and the bottom cover folding member II will first come into contact with the bottom cover on the right side of the cardboard box, and further guide its folding through the first inclined guiding surface. Further, when the bottom cover on the left side of the cardboard box is located at the tongue-fastening member position, the tongue-fastening drive member drives the tongue-fastening member to rotate, thereby folding the bottom cover on the left side of the cardboard box. Further, when the top cover of the cardboard box passes through the glue gun position, the glue gun can drip glue on the top cover. Further, when the top cover passes through the top cover folding member I and the top cover folding member II, the second inclined guiding surface guides the folding of the top cover to achieve fixation. Further, when the folded top cover slides to the tape assembly position, the tape assembly can stick the tape on the top cover to achieve fixation. This product has two fixing methods, and either one can be selected for fixation. Of course, it is also possible to use both fixing methods simultaneously.

[0006] A further setting of the present utility model: The box-pushing support is provided with a first pushing member and a second pushing member. The first pushing member and the second pushing member are arranged at intervals to form an assembly area for the cardboard box to enter. The box-pushing drive assembly includes a box-pushing drive member I that drives the box-pushing support to rotate and swing, and a box-pushing drive member II that drives the box-pushing support to move left and right. The machine frame is also provided with a support frame for supporting the cardboard box. When the box-pushing support descends and disengages from the cardboard box, the support frame supports the bottom of the cardboard box, and a rotating roller connected to the support frame is rotatably provided on the machine frame.

[0007] With the above technical solution, after the cardboard box is filled, through the cooperation of the box-pushing drive member I and the box-pushing drive member II, the cardboard box can be located in the assembly area. Further, the first pushing member pushes the cardboard box to move rightward with the box-pushing support to achieve the handling of the first group. When the second cardboard box is filled, the cooperation of the box-pushing drive member I and the box-pushing drive member II can cause the box-pushing support to disengage from the first cardboard box. At this time, the support frame prevents the first cardboard box from falling. The box-pushing support performs the same operation to assemble and push the second cardboard box. When the box-pushing support moves rightward to the designated position, the second pushing member will first contact the first cardboard box, thereby pushing it onto the rotating roller, and the reciprocating operation can continuously push the cardboard box backward.

[0008] A further setting of the present utility model: A top pressing plate is further provided above the sealing channel on the machine frame. The top pressing plate can be adjusted relative to the machine frame in the vertical direction. Two groups of mounting plates are provided on the machine frame. The sealing channel is formed by the two groups of mounting plates arranged at intervals, and at least one mounting plate can be guided and adjusted in the machine frame in the front-rear direction.

[0009] With the above technical solution, the top pressing plate can prevent the cardboard box from tilting during transportation, and by adjusting the top pressing plate, it can be used for cardboard boxes of different heights. By adjusting the mounting plates, the width of the sealing channel can be adjusted, so as to be used for cardboard boxes of different widths.

[0010] Further setting of the present utility model: A suction nozzle for adsorbing the carton is arranged on the first pushing member.

[0011] By adopting the above technical solution, the carton can be sucked and carried, and the offset of the carton can be prevented.

[0012] Further setting of the present utility model: A discharge table is arranged on the frame at the rear side of the rotating roller, and a turnover frame and a turnover driving member for driving the turnover frame to rotate are hinged on the discharge table.

[0013] By adopting the above technical solution, the carton can be discharged with its direction changed. Description of the drawings

The frame 1 is provided with a box pushing bracket 3 for receiving and pushing a carton and a box pushing drive assembly 4 for driving the box pushing bracket 3 to move. On both sides of the sealing channel 2 on the frame 1, a bottom cover folding structure 5 and a top cover folding structure 6 are sequentially arranged. When the box pushing bracket 3 moves, it can drive the carton to pass through the bottom cover folding structure 5 and the top cover folding structure 6 in sequence. The bottom cover folding structure 5 includes a bottom cover folding member I 51 and a bottom cover folding member II 52 arranged at intervals in the front-rear direction (the bottom cover folding member is most preferably an extrusion plate, and of course, it can also be an extrusion rod). Both the bottom cover folding member I 51 and the bottom cover folding member II 52 have a first inclined guiding surface 53 for guiding the folding of the bottom cover on the right side. At positions corresponding to the bottom cover folding member I 51 and the bottom cover folding member II 52 on the frame 1, a tongue punching member 54 is rotatably provided and a tongue punching drive member 55 for driving the tongue punching member 54 to rotate (the tongue punching drive member 55 is most preferably a motor, and of course, it can also be an electric cylinder or a cylinder). The rotation of the tongue punching member 54 can enter and exit the sealing channel 2 to fold another bottom cover onto the box body. The top cover folding structure 6 is provided with two groups arranged at intervals in the front-rear direction. Each group of the top cover folding structure 6 includes a top cover folding member I 61 and a top cover folding member II 62 arranged at intervals in the up-down direction (the top cover folding member is most preferably an extrusion rod, and of course, it can also be an extrusion plate). Both the top cover folding member I 61 and the top cover folding member II 62 have a second inclined guiding surface 63 for guiding the folding. In the embodiment of the present utility model, a glue gun 7 is further provided on the frame 1 at the position of the bottom cover folding structure 5. When the carton passes through the position of the glue gun 7, the outlet end of the glue gun 7 corresponds to the top cover position. A tape assembly 8 (the tape assembly 8 is composed of a cutter, a guiding roller, a film roller, etc., which belongs to the prior art and will not be introduced in detail herein) is provided on the right side of each top cover folding structure 6. A abutting member 9 for restricting the reset after the top cover is folded is further provided between the tape assembly 8 and the top cover folding structure 6 (the abutting member 9 is most preferably an abutting plate, and an extrusion surface can also be provided on the abutting plate, and of course, it can also be an extrusion rod, etc.). The abutting member 9 can prevent the top cover from resetting after separating from the top cover folding structure 6, so as to ensure that the tape assembly 8 can adhere the tape to the carton.

[0024] With the above technical solution, during use, the box-pushing drive assembly 4 drives the box-pushing bracket 3 to move, thereby pushing the carton to the position of the sealing channel 2. At this time, the bottom cover folding member I 51 and the bottom cover folding member II 52 will first come into contact with the bottom cover on the right side of the carton, and further guide its folding through the first inclined guiding surface 53. Further, when the bottom cover on the left side of the carton is located at the tongue-locking member 54 position, the tongue-locking drive member 55 drives the tongue-locking member 54 to rotate, thereby folding the bottom cover on the left side of the carton. Further, when the top cover of the carton passes through the position of the glue gun 7, the glue gun 7 can drip glue on the top cover. Further, when the top cover passes through the top cover folding member I 61 and the top cover folding member II 62, the second inclined guiding surface 63 guides the folding of the top cover to achieve fixation. Further, when the folded top cover slides to the position of the tape assembly 8, the tape assembly 8 can stick the tape on the top cover to achieve fixation. This product has two fixing methods, and either one can be selected for fixation. Of course, it is also possible to use both fixing methods simultaneously.

[0025] A first pushing member 31 and a second pushing member 32 are provided on the box pushing bracket 3 (the first pushing member 31 is most preferably a push rod, and the second pushing member 32 is most preferably a push plate). The first pushing member 31 and the second pushing member 32 are arranged at intervals to form an assembly area 33 for the carton to enter (most preferably, an avoidance space is provided in the assembly area 33 to facilitate the rotation of the box pushing bracket 3). The box pushing drive assembly 4 includes a box pushing drive member I 41 for driving the box pushing bracket 3 to rotate and swing, and a box pushing drive member II 42 for driving the box pushing bracket 3 to move left and right (the box pushing drive member I 41 is most preferably a motor, and the box pushing drive member II 42 is most preferably a synchronous belt and a motor. The installation method can be to set an installation bracket on the synchronous belt, the box pushing bracket is rotatably arranged on the installation bracket, the box pushing drive member I 41 drives the box pushing bracket 3 to rotate relatively through a swing arm, and the synchronous belt drives the box pushing bracket 3 to slide left and right. Of course, the box pushing drive member I 41 and the box pushing drive member II 42 can also be cylinders or electric cylinders. The specific installation belongs to the prior art and will not be introduced in detail in this article). A support frame 10 for supporting the carton is further provided on the frame 1. When the box pushing bracket 3 descends and disengages from the carton, the support frame 10 supports the bottom of the carton, and a rotating roller 20 connected to the support frame 10 is rotatably arranged on the frame 1 (the rotating roller 20 can also be one or more driving rollers, which rotate relatively to drive the carton forward). After the carton is filled, the cooperation of the box pushing drive member I 41 and the box pushing drive member II 42 can place the carton in the assembly area 33. Further, the first pushing member 31 pushes the carton to move rightward with the box pushing bracket 3 to realize the handling of the first group. When the second carton is filled, the cooperation of the box pushing drive member I 41 and the box pushing drive member II 42 can cause the box pushing bracket 3 to disengage from the first carton. At this time, the support frame 10 prevents the first carton from falling. The box pushing bracket 3 performs the same operation to assemble and push the second carton z. When the box pushing bracket 3 moves rightward to a specified position, the second pushing member 32 will first contact the first carton and push it onto the rotating roller 20. By repeating the operation, the carton can be continuously pushed backward.

[0026] Above the sealing channel 2 on the frame 1, there is also a top pressing plate 30. The top pressing plate 30 can be adjusted relative to the frame 1 in the vertical direction (most preferably, an installation frame is provided on the frame 1. The top pressing plate 30 can be adjusted by a screw or electrically, and a long slot hole arranged in the front-rear direction can also be provided on the installation frame to adjust the distance in width).
