This mechanism drives the end-pressure ball screw to rotate, and the end-pressure ball screw extends along the height direction. The package can be conveyed to the processing station of the bottom pressure frame via a conveying device, where the package's compactness is adjusted.

[0034] Detailed Implementation

[0035] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0036] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0037] The following description, with reference to the accompanying drawings, describes the package compactness adjustment device and the packaging machine of this application.

[0038] like Figures 1 to 5As shown, this application provides a package compactness adjustment device, which includes a support frame 10, an end-pressing assembly, a side-pressing assembly 40, and a drive assembly 50. The end-pressing assembly has a top-pressing frame 20 and a bottom-pressing frame 30 mounted on the support frame 10, and the top-pressing frame 20 and the bottom-pressing frame 30 can move relatively closer or relatively farther apart along the height direction. A processing station 34 for placing the package is formed on the bottom-pressing frame 30. The side-pressing assembly 40 has two first side-pressing plates 41 mounted on the support frame 10. The two first side-pressing plates 41 are respectively located on opposite sides of the processing station 34 and can move relatively closer or relatively farther apart. The drive assembly 50 includes a rotary drive mechanism 51, an end-pressure ball screw 52, ​​and two first side-pressure ball screws 53. The end-pressure ball screw 52 is connected to the top pressure frame 20 and / or the bottom pressure frame 30 through a threaded pair. The two first side-pressure ball screws 53 are respectively located on opposite sides of the end-pressure ball screw 52 and are respectively connected to the two first side pressure plates 41 one-to-one through a threaded pair. The rotary drive mechanism 51 is mounted on the support frame 10 and is used to drive the end-pressure ball screw 52 to rotate. A meshing transmission bevel gear set 54 is provided between the end-pressure ball screw 52 and the two first side-pressure ball screws 53.

[0039] A rotary drive mechanism 51 is mounted on the support frame 10. The rotary drive mechanism 51 drives the end-pressure ball screw 52 to rotate, and the end-pressure ball screw 52 extends along the height direction. The package can be conveyed to the processing station 34 of the bottom pressure frame 30 via a conveying device, where the package's compactness is adjusted. The rotation of the end-pressure ball screw 52 drives the top pressure frame 20 and the bottom pressure frame 30 to move relatively closer or further apart along the height direction, thereby adjusting the distance between the top pressure frame 20 and the bottom pressure frame 30, and thus adjusting the compactness of the package in the height direction at the processing station 34. Two first-side-pressure ball screws 53 are respectively located on opposite sides of the end-pressure ball screw 52. A meshing transmission bevel gear set 54 is provided between the end-pressure ball screw 52 and the two first-side-pressure ball screws 53. Through the meshing transmission bevel gear set 54, the rotation of the end-pressure ball screw 52 drives the two first-side-pressure ball screws 53 to rotate. Two first-side pressure ball screws 53 are connected to two first-side pressure plates 41 respectively via threaded pairs. Rotation of the two first-side pressure ball screws 53 causes the two first-side pressure plates 41 to move closer or further apart in the horizontal direction, thereby adjusting the distance between the two first-side pressure plates 41 and thus adjusting the compactness of the package on the processing station 34 in the horizontal direction. The horizontal direction can be either the width or length direction of the package.

[0040] The packing compactness adjustment device in this application uses a rotary drive mechanism 51 to drive the end-pressure ball screw 52 to rotate, causing the top pressure frame 20 and the bottom pressure frame 30 to move relatively closer or further apart, thereby adjusting the compactness of the packing in the height direction. Furthermore, the end-pressure ball screw 52, ​​through a meshing transmission bevel gear set 54, can drive two first side-pressure ball screws 53 to rotate, causing the two first side pressure plates 41 to move relatively closer or further apart, thereby adjusting the compactness of the packing in the horizontal direction. The movement of the top pressure frame 20, the bottom pressure frame 30, and the two first side pressure plates 41 are all accomplished by the rotary drive mechanism 51, saving costs and reducing the size of the packing compactness adjustment device.

[0041] The end-pressure ball screw 52 can be connected to the top pressure frame 20 via a threaded pair. Rotation of the end-pressure ball screw 52 can cause the top pressure frame 20 to move relatively closer to or relatively farther away from the bottom pressure frame 30. Alternatively, the end-pressure ball screw 52 can be connected to the bottom pressure frame 30 via a threaded pair. Rotation of the end-pressure ball screw 52 can cause the bottom pressure frame 30 to move relatively closer to or relatively farther away from the top pressure frame 20. Alternatively, the end-pressure ball screw 52 can be connected to both the top pressure frame 20 and the bottom pressure frame 30 via a threaded pair. Rotation of the end-pressure ball screw 52 can cause the top pressure frame 20 and the bottom pressure frame 30 to move relatively closer to or relatively farther away.

[0042] In the embodiments of this application, please refer to Figure 2 The meshing transmission bevel gear set 54 includes a first driving bevel gear 541 and two first driven bevel gears 542. The first driving bevel gear 541 meshes with the two first driven bevel gears 542 for transmission. The first driving bevel gear 541 is fixedly connected to the end pressure ball screw 52 and is coaxially arranged. The two first driven bevel gears 542 are respectively connected to the two first side pressure ball screws 53 one-to-one.

[0043] The first driving bevel gear 541 is fixedly connected to the end pressure ball screw 52, ​​and the first driving bevel gear 541 and the end pressure ball screw 52 are coaxially arranged along the height direction, i.e., the up-down direction. The rotation of the end pressure ball screw 52 drives the first driving bevel gear 541 to rotate, and the rotation of the first driving bevel gear 541 drives the two first driven bevel gears 542 that mesh with it to rotate, causing the two first side pressure ball screws 53 to rotate, thereby causing the two first side pressure plates 41 to move relatively closer or relatively farther apart, so as to adjust the tightness of the package in the horizontal direction.

[0044] Specifically, the two first side pressure plates 41 are relatively close to each other, which reduces the distance between the two first side pressure plates 41, thereby making the package tighter in the horizontal direction; the two first side pressure plates 41 are relatively far apart, which increases the distance between the two first side pressure plates 41, thereby making the package looser in the horizontal direction.

[0045] Based on this, the side pressure assembly 40 may further include two second side pressure plates 42, and the drive assembly 50 may further include two second side pressure ball screws. The two second side pressure ball screws are respectively located on the left and right sides of the end pressure ball screw 52 and are respectively connected to the two second side pressure plates 42 one-to-one through threaded pairs. A meshing transmission bevel gear set 54 is provided between the end pressure ball screw 52 and the two second side pressure ball screws. The two second side pressure ball screws are respectively located on the left and right sides of the end pressure ball screw 52, ​​and the two first side pressure ball screws 53 are respectively located on the front and rear sides of the end pressure ball screw 52. Then, the rotary drive mechanism 51 drives the end pressure ball screw 52 to rotate, which can simultaneously drive the top pressure frame 20, the bottom pressure frame 30, the two first side pressure plates 41 and the two second side pressure plates 42 to move from the top, bottom, front, back and left sides of the package body, respectively, to compress the six sides of the package body, making the shape of the package body more regular.

[0046] Alternatively, the side pressure assembly 40 includes two pairs of first side pressure plates 41, one pair of first side pressure plates 41 distributed along the front-back direction and the other pair of first side pressure plates 41 distributed along the left-right direction, so as to achieve compression of the six sides of the package.

[0047] In the embodiments of this application, please refer to Figure 2 The rotary drive mechanism 51 includes a rotary drive member 511, a second driving bevel gear 512, and a second driven bevel gear 513. The output shaft of the rotary drive member 511 is arranged laterally and is drivenly connected to the second driving bevel gear 512. The second driven bevel gear 513 is fixedly connected to the end pressure ball screw 52 and is spaced apart from the first driving bevel gear 541 along the height direction. The second driving bevel gear 512 and the second driven bevel gear 513 mesh and transmit power.

[0048] The output shaft of the rotary drive 511 is arranged laterally and extends in the front-to-back direction. The rotary drive 511 is driven by the second driving bevel gear 512. The rotary drive 511 drives the second driving bevel gear 512 to rotate, and the second driving bevel gear 512 drives the second driven bevel gear 513, which meshes with it, to rotate, thereby causing the end-pressure ball screw 52 to rotate. Through the cooperation of the rotary drive 511, the second driving bevel gear 512, and the second driven bevel gear 513, the transmission is stable and reliable. Furthermore, the laterally arranged output shaft of the rotary drive 511 makes the structural layout of the drive assembly 50 more reasonable and the output more stable.

[0049] Among them, the rotary drive component 511 can be a motor, which has the advantages of stable output and high precision.

[0050] In another embodiment, the rotary drive 511 can also be directly set at the upper end of the end pressure ball screw 52, ​​and the rotary drive 511 directly drives the end pressure ball screw 52 to rotate, without setting the second driving bevel gear 512 and the second driven bevel gear 513.

[0051] In the embodiments of this application, please refer to Figure 3 and Figure 4 The end pressure ball screw 52 has a first threaded section and a second threaded section with opposite directions of rotation. The first threaded section and the second threaded section are respectively connected to the top pressure frame 20 and the bottom pressure frame 30 through threaded pairs.

[0052] The first and second threaded segments are spaced apart in the vertical direction, and their rotation directions are opposite. The first threaded segment is connected to the top pressure frame 20 via a threaded pair, and the second threaded segment is connected to the bottom pressure frame 30 via a threaded pair. By setting the first and second threaded segments with opposite rotation directions on the end pressure ball screw 52, ​​the rotation of the end pressure ball screw 52 can simultaneously drive the top pressure frame 20 and the bottom pressure frame 30 to move, so that the top pressure frame 20 and the bottom pressure frame 30 are relatively closer or relatively farther apart, thereby improving the efficiency of the top pressure frame 20 and the bottom pressure frame 30 in compressing the package body in the vertical direction.

[0053] Among them, the threaded pair can be a nut, which is threadedly connected to the threaded section. The nut can be set on the top pressure frame 20 and the bottom pressure frame 30.

[0054] In the embodiments of this application, please refer to Figure 3 and Figure 4 The bottom pressure frame 30 includes a first connecting plate 31, a bottom pressure plate 32, and a first mounting plate 33 connected between the first connecting plate 31 and the bottom pressure plate 32. The first connecting plate 31 is connected to the first threaded section through a threaded pair. The bottom pressure plate 32 is located on the side of the first connecting plate 31 near the top pressure frame 20, and a processing station 34 for placing the package is formed on the bottom pressure plate 32.

[0055] The first connecting plate 31 is connected to the first threaded section via a threaded pair. The rotation of the end-pressure ball screw 52 can drive the first connecting plate 31 to move in the vertical direction. The package is placed on the processing station 34 of the bottom pressure plate 32. The bottom pressure plate 32 is located on the side of the first connecting plate 31 closer to the top pressure frame 20, that is, the bottom pressure plate 32 is located on the lower side of the first connecting plate 31. The package is located between the bottom pressure plate 32 and the top pressure frame 20. The bottom pressure plate 32 moves relatively closer to or relatively farther away from the top pressure frame 20 to adjust the tightness of the package.

[0056] The first mounting plate 33 is connected between the first connecting plate 31 and the bottom pressure plate 32. The first mounting plate 33 extends in the vertical direction. There can be at least two first mounting plates 33, which makes the connection between the first connecting plate 31 and the bottom pressure plate 32 more stable and reliable, and improves the structural strength of the bottom pressure frame 30.

[0057] A processing seat can be provided on the bottom pressure plate 32 to increase the contact area between the bottom pressure plate 32 and the package body, so that the bottom pressure plate 32 can better support the package body.

[0058] In the embodiments of this application, please refer to Figure 3 and Figure 4 The top pressure frame 20 includes a second connecting plate 21, a top pressure plate 22, and a second mounting plate 23 connected between the second connecting plate 21 and the top pressure plate 22. The second connecting plate 21 is connected to the second threaded section through a threaded pair. The top pressure plate 22 is located on the side of the second connecting plate 21 away from the first threaded section, and the top pressure plate 22 is used to abut against the package body.

[0059] The second connecting plate 21 is connected to the second threaded section via a threaded pair. Rotation of the end-pressure ball screw 52 can drive the second connecting plate 21 to move vertically. The top pressure plate 22 is located on the side of the second connecting plate 21 furthest from the first threaded section, i.e., below the second connecting plate 21. The top pressure plate 22 is used to abut against the package body to compress it and adjust its tightness. Furthermore, the upper side of the top pressure plate 22 can abut against the lower end of the end-pressure ball screw 52 to limit its movement, preventing the second connecting plate 21 from moving excessively and disengaging from the end-pressure ball screw 52. The distance between the top pressure plate 22 and the second connecting plate 21 is the distance the top pressure plate 22 can move vertically.

[0060] In the embodiments of this application, please refer to Figure 1 The support frame 10 includes a fixed plate 11 and at least two support legs 12 connected to the fixed plate 11. The at least two support legs 12 are spaced apart. The end pressure ball screw 52 is rotatably mounted on the fixed plate 11, and the rotation drive mechanism 51 is mounted on the fixed plate 11.

[0061] At least two support legs 12 are spaced apart and connected to the fixed plate 11 to support the fixed plate 11. Furthermore, the at least two support legs 12 are located on the front and rear sides of the base frame 30 respectively, to prevent the support legs 12 from interfering with or obstructing the vertical movement of the base frame 30. A rotary drive mechanism 51 is mounted on the fixed plate 11 to facilitate its installation. An end-pressure ball screw 52 is rotatably mounted on the fixed plate 11, and the rotary drive mechanism 51 can drive the end-pressure ball screw 52 to rotate relative to the fixed plate 11.

[0062] The number of supporting legs 12 can be two, three, four, or other numbers. The number of supporting legs 12 can be flexibly adjusted according to actual needs, such as... Figure 1 As shown, there are four supporting legs 12.

[0063] In the embodiments of this application, please refer to Figure 3The support frame 10 also includes a limiting seat 16, which is connected to the fixing plate 11. The limiting seat 16 and the fixing plate 11 together form a lateral movement space 17. The first side pressure plate 41 moves within the lateral movement space 17, and the limiting seat 16 and the fixing plate 11 are respectively used to abut against the two sides of the first side pressure plate 41.

[0064] The limiting seat 16 is U-shaped, and the open end of the limiting seat 16 is connected to the side of the fixing plate 11. The limiting seat 16 and the fixing plate 11 together form a lateral movement space 17 for the first side pressure plate 41 to move. The limiting seat 16 and the fixing plate 11 are respectively used to abut against the two sides of the first side pressure plate 41 to limit the movement of the first side pressure plate 41 in the horizontal direction, so as to prevent the first side pressure plate 41 from moving excessively and disengaging from the first side pressure ball screw 53, making the movement of the first side pressure plate 41 more stable and reliable.

[0065] In the embodiments of this application, please refer to Figure 3 The support frame 10 also includes a third guide rod 15 laterally connected to the fixed plate 11, and the first side pressure plate 41 is movably mounted on the third guide rod 15. The third guide rod 15 extends horizontally and is consistent with the moving direction of the first side pressure plate 41. By setting the third guide rod 15 to guide the first side pressure plate 41, the first side pressure plate 41 can move stably, thereby improving the stability and reliability of the package compactness adjustment device.

[0066] In the embodiments of this application, please refer to Figure 5 The support frame 10 also includes a first guide rod 13 connected to the fixed plate 11 and extending along the height direction. The top pressure frame 20 is movably mounted on the first guide rod 13. By setting the first guide rod 13 to guide the top pressure frame 20, the top pressure frame 20 can move stably in the height direction, thereby improving the stability and reliability of the package compaction adjustment device.

[0067] In the embodiments of this application, please refer to Figure 3 The support frame 10 also includes a second guide rod 14 connected to the fixed plate 11 and extending along the height direction. The bottom pressure frame 30 is movably mounted on the second guide rod 14. By setting the second guide rod 14 to guide the bottom pressure frame 30, the bottom pressure frame 30 can move stably in the height direction, further improving the stability and reliability of the package compaction adjustment device.

[0068] In the embodiments of this application, please refer to Figure 5 The first end of the end pressure ball screw 52 is provided with a first limiting plate 521. The first limiting plate 521 is used to abut against the top pressure frame 20. By setting the first limiting plate 521, the top pressure frame 20 is limited to avoid excessive movement of the top pressure frame 20 and disengagement from the end pressure ball screw 52, ​​so that the movement process of the top pressure frame 20 is more stable and reliable.

[0069] In the embodiments of this application, please refer to Figure 5 The second end of the end pressure ball screw 52 is provided with a second limiting plate 522.
