Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically a folding tray sealing mechanism for an automated packaging machine. Background Technology

[0002] The folding tray sealing mechanism of automated packaging machines is mainly used in scenarios such as paper box packaging bags in the daily necessities and food industries. Its core function is to fold and shape the packaging material according to a preset shape through the coordinated action of the mechanical structure, achieve precise switching of work positions with the help of the rotating tray, and finally complete the sealing. In the existing automatic sealing device for paper boxes with patent application number CN202011385912.7, the paper box is folded by multiple piston rods and rotating rods. However, its driving method is piston cylinder and motor. When folding, the method of lowering and pushing can easily cause misalignment on the left and right sides and the top and bottom sides of the paper box, which can easily cause uneven folding. In addition, its folding requires the linkage of multiple electrical devices, and its folding method is too complicated. Utility Model Content

[0003] This invention provides a folding tray sealing mechanism for an automated packaging machine, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A folding tray turntable sealing mechanism for an automated packaging machine includes a tray and a folding mechanism. The folding mechanism has six folding mechanisms arranged around the surface of the tray. A rotating shaft for rotation is provided at the central axis position of the bottom of the tray. A rotating rod and a transmission structure are provided at the bottom of the tray, and the transmission structure is arranged at the bottom of the tray corresponding to the folding mechanism. The rotating rod rotates on both sides at the corresponding position of each folding mechanism. The tray is also provided with a support mechanism, a track bar, and a guide bar below it. The guide bar is set on the surface of the support mechanism. The track bar and the support mechanism are in a fixed state. The transmission structure rotates around the pivot shaft along the surface of the guide bar. The guide bar lifts the transmission structure to elastically raise it and causes the transmission structure to move upward to open and close the folding mechanism. When the tray rotates, the support mechanism presses against and drives the rotating rod to rotate.

[0005] A preferred technical solution: The folding mechanism includes a push rod, a first folding plate, a connecting plate, a swing plate, a forming box, a first spring, a movable rod, and a linkage mechanism. The linkage mechanism is located at the upper end of the forming box for rotational opening and closing, and is connected to the corresponding transmission structure through the surface of the tray. The forming box is fixed to the surface of the tray. The movable rod is symmetrically arranged on the left and right sides of the forming box, and is vertically connected to the rotating rod through the surface of the tray. The movable rod is elastically connected to the side of the swing plate through the first spring. There are two swing plates, and the swing plates rotate and swing on the surface of the tray. The swing plates are symmetrically distributed on the left and right sides of the forming box. A connecting plate is provided at the outer end of the swing plate, and the connecting plate is connected to the side of the movable rod through the push rod. When the movable rod rotates, it drives the connecting plate connected to the push rod to rotate and swing the swing plate. The connecting plate is provided with a first folding plate, and the first folding plate swings and closes on the left and right sides corresponding to the opening end of the forming box.

[0006] A preferred technical solution: The linkage mechanism includes a fixed block, a transmission handle, a second folding plate, a rotating block, a support bar, a round rod, a long strip plate, and a telescopic rod. The second folding plate is fixed to the outside of the support bar. The lower end of the support bar passes through the fixed block fixed to the outside of the molding box for vertical movement. The telescopic rod connects the support bar and the long strip plate. The long strip plate is located at the upper end of the round rod and passes through the interior of the upper end of the molding box. The rotating blocks are symmetrically distributed at both ends of the round rod. The transmission handle passes through the interior of the tray and connects to the transmission structure. When the transmission structure is elastically compressed, the transmission handle drives the rotating block to rotate and causes the long strip plate and the round rod to rotate. At this time, the telescopic rod drives the second folding plate on the support bar to close at the opening end of the molding box.

[0007] A preferred technical solution: The transmission structure includes a third folding plate, a metal rod, a force-bearing plate, a roller, and a second spring. There are two force-bearing plates, which are distributed in a staggered parallel state. The metal rod at the upper end of the force-bearing plate passes through the tray and is connected to the transmission handle. The upper end of the force-bearing plate is provided with symmetrically distributed second springs, and the force-bearing plate is elastically connected to the lower surface of the tray through the second springs. The upper end of the force-bearing plate is provided with a third folding plate. The roller at the lower end of the force-bearing plate slides in cooperation with the guide strip, and the force-bearing plate elastically drives the third folding plate upward through the second spring to close at the opening end of the forming box.

[0008] A preferred technical solution: The support mechanism includes a fixed seat, a force-bearing rod, a concave plate, and a support seat. The support seat is located in the middle of the concave plate and supports the connecting guide strip through the support seat. The concave plate is fixed by the fixed seat at its lower end. Four force-bearing rods are installed on the concave plate, and the force-bearing rods guide the rotating rod to rotate.

[0009] Compared with existing technologies, this technical solution has the following advantages: In this invention, the arched structure of the track bar is symmetrically arranged relative to the guide bar with the rotation axis as the axis of symmetry. When the guide bar guides the transmission structure, the force-bearing rod on the support mechanism blocks the rotating rod, achieving the effect of left and right closure. The arched structure is located on the other side of the track bar opposite to the guide bar. After the left and right closure is completed, the arched structure supports the swing plate and the third folding plate to perform the up and down closure, so that the left and right folding and up and down folding are avoided and folded in an orderly manner.

[0010] In this invention, after the tray rotates, the first folding plates on the left and right sides of the opening end of the molding box swing and the second folding plate tangent to each other and rises and falls at the opening end of the molding box. Since the folding angle of the second folding plate tangent to each other and rising and falling at the opening end of the molding box is directly a right angle, and the first folding plates on the left and right sides swing slowly at 90° to fold, after the vertical folding is completed, when folding left and right, an arc will be formed at the position where the vertical folding has already been completed. The arc will be slowly folded to 90° by the swing of the left and right folding, thereby avoiding the misalignment of vertical and horizontal folding and preventing uneven folding. Folding can be achieved by providing intermittent rotation to the tray, avoiding the problem of complex linkage of multiple folding structures. Attached Figure Description

Detailed Implementation

[0020] like Figures 1 to 7 As shown, this utility model proposes a folding tray turntable sealing mechanism for an automated packaging machine, including a tray 1 and a folding mechanism 2. The folding mechanism 2 has six folding mechanisms arranged around the surface of the tray 1. A rotating shaft 22 for rotation is provided at the central axis position of the bottom of the tray 1. A rotating rod 21 and a transmission structure 23 are provided at the bottom of the tray 1, and the transmission structure 23 is provided at the bottom of the tray 1 corresponding to the folding mechanism 2. The rotating rod 21 rotates on both sides at the corresponding position of each folding mechanism 2. Below the tray 1, there is also a support mechanism 11, a track 12, and a guide bar 13. The guide bar 13 is set on the surface of the support mechanism 11. The track 12 and the support mechanism 11 are in a fixed state. The transmission structure 23 rotates around the rotating shaft 22 as the central axis along the surface of the guide bar 13. The guide bar 13 lifts the transmission structure 23 to elastically raise it, and causes the transmission structure 23 to move upward to open and close the folding mechanism 2. When the tray 1 rotates, the support mechanism 11 presses against and drives the rotating rod 21 to rotate.

[0021] Furthermore, an external output motor is provided at the lower end of the rotating shaft 22, and the support mechanism 11 and the track bar 12 are fixed on the base. The motor output drives the rotating shaft 22 to rotate intermittently, so that the folding mechanism 2 blocks the surface of the guide bar 13. The track bar 12 has a notch. When the folding mechanism 2 rotates to the notch position of the track bar 12, the folding mechanism 2 is in a closed state.

[0022] Furthermore, the guide bar 13 and the track bar 12 are located in the same ring shape, and the side of the guide bar 13 is arc-shaped, which has the effect of guiding the transmission structure 23 into the track bar 12.

[0023] The folding mechanism 2 includes a push rod 31, a first folding plate 32, a connecting plate 33, a swing plate 34, a forming box 35, a first spring 36, a movable rod 37, and a linkage mechanism 38. The linkage mechanism 38 is located on the upper end of the forming box 35 and rotates to open and close. The linkage mechanism 38 passes through the corresponding transmission structure 23 from the surface of the tray 1 and is fixed to the surface of the tray 1. The movable rod 37 is symmetrically arranged on the left and right sides of the forming box 35 and passes vertically through the surface of the tray 1 to connect with the rotating rod 21. The movable rod 37 is connected to the first spring 36 by the first spring 37. 6. Two swing plates 34 are provided on the side of the swing plate 34. The swing plates 34 rotate and swing on the surface of the tray 1. The swing plates 34 are symmetrically distributed on the left and right sides of the molding box 35. A connecting plate 33 is provided at the outer end of the swing plate 34. The connecting plate 33 is connected to the side of the movable rod 37 through the push rod 31. When the movable rod 37 rotates, it drives the connecting plate 33 connected to the push rod 31 to rotate and swing the swing plate 34. The connecting plate 33 is provided with a first folding plate 32. The first folding plate 32 swings and closes on the left and right sides of the opening end of the molding box 35.

[0024] Furthermore, the first spring 36, fixed by the swing plate 34, causes the movable rod 37 to generate an elastic rotational force. Thus, when the movable rod 37 is subjected to the rotational force of the rotating rod 21, the movable rod 37 rotates elastically and drives the connecting plate 33 connected to the push rod 31 to swing elastically at the outer end of the swing plate 34. This causes the first folding plate 32 at the outer end of the connecting plate 33 to close symmetrically at the opening of the forming box 35. When the first spring 36 is stationary, the opening of the forming box 35 is open, and the square packaging bag enters the forming box 35. When the first folding plate 32 closes the opening of the forming box 35, the opening of the packaging bag is folded. It is worth noting that after the packaging bag is placed in the forming box 35, square materials will be fed in vertically. When the material folds the packaging bag with the first folding plate 32, a reaction force is generated at its folding corner, thus folding the packaging bag.

[0025] The linkage mechanism 38 includes a fixed block 341, a transmission handle 342, a second folding plate 343, a rotating block 344, a support bar 345, a round rod 346, a long strip 347, and a telescopic rod 348. The second folding plate 343 is fixed to the outside of the support bar 345. The lower end of the support bar 345 passes through the fixed block 341 fixed to the outside of the molding box 35 for vertical movement. The telescopic rod 348 connects the support bar 345 and the long strip 347. 47 is set at the upper end of the round rod 346. The long strip 347 passes through the interior of the upper end of the molding box 35, and the rotating blocks 344 are symmetrically distributed at both ends of the round rod 346. The transmission handle 342 passes through the interior of the tray 1 and connects to the transmission structure 23. When the transmission structure 23 is elastically compressed, the transmission handle 342 drives the rotating blocks 344 to rotate, and causes the long strip 347 and the round rod 346 to rotate. At this time, the telescopic rod 348 drives the second folding plate 343 on the support bar 345 to close at the opening end of the molding box 35.

[0026] Furthermore, the upper end of the transmission handle 342 is provided with a bearing connected to the outer side of the rotating block 344. When the transmission handle 342 is compressed and moves upward by the transmission structure 23, the rotating block 344 rotates and moves outside the molding box 35. As a result, the round rod 346 and the long strip plate 347 drive the telescopic rod 348 to rotate and swing. The telescopic rod 348 has a telescopic effect, so it extends and retracts when it rotates and swings. The telescopic rod 348 moves vertically in the fixed block 341 through the support bar 345. Then, the second folding plate 343 moves and closes on the upper side of the opening end of the molding box 35.

[0027] The transmission structure 23 includes a third folding plate 231, a metal rod 232, a force plate 233, a roller 234, and a second spring 235. Two force plates 233 are provided, arranged in a staggered parallel configuration. The metal rod 232 at the upper end of the force plate 233 passes through the tray 1 and connects to the transmission handle 342. Symmetrically distributed second springs 235 are provided at the upper end of the force plate 233, and the force plate 233 is elastically connected to the lower surface of the tray 1 via the second springs 235. The third folding plate 231 is provided at the upper end of the force plate 233. The roller 234 at the lower end of the force plate 233 slides in cooperation with the guide strip 13, causing the force plate 233 to elastically drive the third folding plate 231 upwards via the second spring 235, closing the opening of the forming box 35.

[0028] Furthermore, the surface of the track bar 12 is provided with an arc-shaped arched structure. When the transmission handle 342 moves upward to drive the second folding plate 343 to move and close, the roller 234 at the lower end of the force plate 233 needs to slide on the arc-shaped arched structure on the surface of the track bar 12. At this time, the force plate 233 is supported by the arched structure of the track bar 12 and moves upward. The third folding plate 231 closes at the lower side of the opening end of the forming box 35. At the same time, the force plate 233 drives the metal rod 232 upward to push the connected transmission handle 342, realizing the effect of closing the third folding plate 231 and the second folding plate 343 on the upper and lower sides of the opening end of the forming box 35. When the roller 234 at the lower end of the force plate 233 disengages from the arched structure of the track bar 12, the force plate 233 drives the metal rod 232 to move downward under the elastic force of the second spring 235. At this time, the third folding plate 231 and the second folding plate 343 are in the open and closed state at the opening end of the forming box 35, providing space for the material to enter.

[0029] The support mechanism 11 includes a fixed seat 41, force-bearing rods 42, a concave plate 43, and a support seat 44. The support seat 44 is located in the middle of the concave plate 43 and supports the guide strip 13. The concave plate 43 is fixed by the fixed seat 41 at its lower end. Four force-bearing rods 42 are installed on the concave plate 43, and the force-bearing rods 42 guide the rotating rod 21 to rotate.

[0030] Furthermore, when the first folding plate 32 and the third folding plate 231 close the opening end of the molding box 35, there is a hollow cross-shaped opening structure in the middle, and the cross-shaped opening structure makes it easy for the tape to stick and seal the folded position from there.

[0031] In this utility model, the fixed base 41 supports the support base 44 and the concave plate 43. When the track bar 12 rotates with the rotating shaft 22, the transmission structure 23 is guided to slide by the guide bar 13 at the upper end of the support base 44. At the same time, the rotating rod 21 is pressed against the side of the force-bearing rod 42. Under the obstruction of the force-bearing rod 42, the rotating rod 21 rotates. The movable rod 37 connected to the rotating rod 21 rotates elastically through the first spring 36, thereby closing the first folding plate 32 at the opening end of the forming box 35. It is necessary to note that the attached... Figure 2The arched structure of the track bar 12 is symmetrically arranged relative to the guide bar 13 with the pivot 22 as the axis of symmetry. When the guide bar 13 guides the transmission structure 23, the force-bearing rod 42 on the support mechanism 11 blocks the rotating rod 21, achieving the effect of left and right closure. The arched structure is located on the other side of the track bar 12 opposite to the guide bar 13. After the left and right closure is completed, the arched structure supports the swing plate 34 and the third folding plate 231 to perform vertical closure, so that the left and right folds and vertical folds are avoided and folded in an orderly manner. Then, after the tray 1 is rotated, the first folding plate 32 on the left and right sides of the opening end of the forming box 35 swings and the second folding plate 343 forms the shape. The second folding plate 343 is tangent and rises and falls at the opening end of the molding box 35. Since the folding angle of the second folding plate 343 is directly right angle at the opening end of the molding box 35, and the first folding plates 32 on the left and right sides swing slowly at 90° to fold, after the vertical folding is completed, when folding left and right, an arc will be formed at the position where the vertical folding has been completed. The arc will be slowly folded to 90° by swinging left and right, thereby avoiding the misalignment of vertical and horizontal folding and preventing uneven folding. This allows folding to be achieved by providing intermittent rotation to the tray 1, avoiding the problem of complex linkage of multiple folding structures.

[0032] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
