[0033] Combination Figure 1-3 as well as Figure 6As shown, an embodiment of the present invention provides a bag clamping and packaging machine, including a base frame 1, a clamping belt 2, a first adjustment module 3, a transmission module 4 and a second adjustment module 5, wherein the transmission module 4 is mounted on the first adjustment module 3, the transmission module 4 is arranged above the clamping belt 2, the transmission module 4 is arranged on the base frame 1, the first adjustment module 3 is used to adjust the height of the transmission module 4, and the second adjustment module 5 is used to adjust the width and height of the clamping belt 2; the transmission module 4 includes a motor 41 and two sets of transmission components, the two sets of transmission components correspond to the two sides of the clamping belt respectively, and the transmission components include a horizontal transmission shaft 42, a vertical transmission shaft 43, an active Wheel 44, driven wheel 45, first horizontal helical gear 46 and first vertical helical gear 47, the motor 41 drives the horizontal transmission shaft 42 to rotate through the first mechanical component (wherein the first mechanical component can be gear transmission, worm gear transmission or sprocket transmission), the first horizontal helical gear 46 is connected to one end of the horizontal transmission shaft 42, the first vertical helical gear 47 is connected to the first end of the vertical transmission shaft 43, the first horizontal helical gear 46 and the first vertical helical gear 47 are meshed, the second end of the vertical transmission shaft 43 is connected to the driving wheel 44, and the driving wheel 44 drives the driven wheel 45 to rotate through the clamping belt 2.

[0034] Based on the above technical scheme, the present invention discloses a bag clamping and packaging machine, wherein a transmission module 4 includes a motor 41 and two groups of transmission components, and the two groups of transmission components are respectively arranged on both sides of the clamping belt 2, so that the motor 41 can drive the horizontal transmission shaft 42 to rotate through the first mechanical component. Due to the meshing of the first horizontal helical gear 46 and the first vertical helical gear 47 and the connection of the second end of the vertical transmission shaft 43 with the driving wheel 44, the rotation of the driving wheel 44 can be driven by the motor 41, and the rotation speed ratio of the first horizontal helical gear 46 and the first vertical helical gear 47 can be controlled to control the rotation speed of the driving wheel 44. In addition, since the two groups of transmission components are of the same size and symmetrical installation positions, the speed of the two groups of transmission components is guaranteed to be consistent, and the rotation directions of the driving wheels 44 on both sides are just opposite and the number of rotations is the same. The horizontal transmission shaft 42 can be used to smoothly transmit power to the driving wheel 44 with zero error, thereby achieving the purpose of synchronous clamping, and effectively solving the speed error problem caused by dual motor drive in the prior art through mechanical transmission. In addition, the height of the transmission module 4 is adjusted by the first adjustment module 3, and the width and height of the clamping belt 2 are adjusted by the second adjustment module 5, so that the clamping belt 2 can be adjusted according to the size of different products. Moreover, the same components and structures are provided on both sides of the clamping belt 2, which is conducive to the force balance during the adjustment process.

[0035] Preferably, the first mechanical assembly includes a chain 61, a driving sprocket 62, a driven sprocket 63 and a transmission rod 64. The motor 41 is connected to the driving sprocket 62. The driving sprocket 62 drives the driven sprocket 63 to rotate through the chain 61. The transmission rod 64 is used to connect the two horizontal transmission shafts 42. The driven sprocket 63 is installed on the transmission rod 64. Therefore, when the motor 41 rotates, the driving sprocket 62 is driven to rotate. Since the chain 61 and the driven sprocket 63 are installed on the transmission rod 64, the motor 41 indirectly drives the transmission rod 64 to rotate. In addition, since the transmission rod 64 connects the two horizontal transmission shafts 42, the speed of both sides of the clamping belt 2 is guaranteed to be consistent.

[0036] Preferably, a coupling 6 is further included, and the vertical transmission shaft 43 is connected to the driving wheel 44 through the coupling 6, thereby ensuring that the rotation speed of the driving wheel 44 is consistent with the rotation speed of the vertical transmission shaft 43.

[0037] Preferably, a tensioning wheel 7 is further included. The tensioning wheel 7 is arranged at one side of the clamping belt 2 and presses the clamping belt 2, so that the tension of the clamping belt 2 can be adjusted.

[0038] Combination Figure 4 -5, preferably, the first adjustment module 3 includes a handle 31, a screw rod 32, a slider 33, a second horizontal helical gear 34, and a second vertical helical gear 35, the transmission module 4 is arranged on the slider 33, the second vertical helical gear 35 is fixed on the screw rod 32, the screw rod 32 passes through the slider 33 and the second vertical helical gear 35, the screw rod 32 and the slider 33 are meshed, the handle 31 is fixedly connected to the second horizontal helical gear 34, and the second horizontal helical gear 34 is meshed with the second vertical helical gear 35. Therefore, the slider 33 can slide on the screw rod 32 by rotating the handle 31 and through the meshing of the second horizontal helical gear 34 and the second vertical helical gear 35, and because the transmission module 4 is arranged on the slider 33, the height of the transmission module 4 can be adjusted.

[0039] Preferably, it further includes a frame 36 and at least two guide rods 37 , the upper and lower ends of the screw rod 32 abut against the frame 36 , the guide rod 37 passes through the slider 33 and the upper and lower ends abut against the frame 36 , wherein the guide rod 37 plays a guiding role.

The height adjustment nut and the width adjustment nut are fixedly arranged in the mounting frame 52. The clamping belt 2 is mounted on the mounting plate 51, and the transmission module 4 is mounted on the mounting frame 52. The height adjustment screw 56 is passed through the height adjustment nut, and the first end of the height adjustment screw 56 is connected to the mounting plate 51, and the second end is fixedly connected to the height adjustment handle 54. The width adjustment screw 55 is passed through the width adjustment nut, and the first end of the width adjustment screw 55 is connected to the transmission module 4, and the second end is fixedly connected to the width adjustment handle 53. Therefore, when it is necessary to adjust the width between the clamping belts 2, the width adjustment handle 53 can be rotated to drive the width adjustment nut to move forward and backward. Since the width adjustment nut is fixedly arranged in the mounting frame 52, the mounting frame 52 will move forward and backward, so that the width adjustment of the clamping belt 2 is realized. The height adjustment of the clamping belt 2 is similar.

[0041] Combination Figure 7 Preferably, the base frame 1 includes a base 11, a plurality of casters 12 and a plurality of foot cups 13, and the casters 12 and foot cups 13 are both arranged below the base 11. Therefore, when transporting, the foot cups 13 are adjusted to be higher than the casters 12, so that the whole device can be pushed to move; when the device needs to be placed, the foot cups 13 are adjusted to be lower than the casters 12, so that the device can be fixed on the ground through the foot cups 13.

[0042] Preferably, the transmission module 5 and the clamping belt 2 can be detachably mounted on the first adjustment module 3, that is, the transmission module 5 and the clamping belt 2 can be removed from the equipment and installed on other conveyor belts to clamp products on the production line. This is simple and convenient and suitable for use on production lines with narrow space.

[0043] In addition, the present invention adopts a combination of the first adjustment module 3 and the second adjustment module 5, so that the adjustment range of the working surface of the clamping belt 2 is large, which can support an adjustment range of 600-1200mm, and the motor 41 is preferably a servo motor, which has the advantages of synchronous clamping, no speed deviation, and smooth movement without slipping through single servo control.
