[0024] Embodiment 1,

[0025] like Figure 1 as well as Figure 2 The follow-up rolling exhaust device for the packaging machine shown includes a machine body, a first conveying component 10, a rolling member 20 and a driving member. An exhaust station is provided on the machine body. The rolling member 20 is installed at the starting end of the first conveying component 10, and the driving member can drive the rolling member 20 to move close to the exhaust station. The rolling member 20 can also rotate close to the conveying end face of the first conveying component 10 during the movement close to the exhaust station. At the same time, the driving member is used to drive the first conveying component 10 to move close to or away from the exhaust station.

[0026] On the basis of the above structure, when the follow-up rolling exhaust device for the packaging machine of the present invention is used, the packaging bags on the packaging machine can be transported to the exhaust station. During this process, the driving member can drive the rolling member 20 to move close to the exhaust station, close to the packaging bags to be heat-sealed at the exhaust station, and at the same time, close to the conveying end surface of the first conveying component 10 to press downward on the packaging bags, so that the packaging bags can be subjected to follow-up rolling exhaust. At the same time, the first conveying component 10 can move close to the second conveying component 40 during the rolling exhaust process, receive the exhausted and heat-sealed packaging bags for follow-up output, and after the rolling member 20 is exhausted, the amount of residual gas after the heat seal of the packaging bag is cut off can be reduced, thereby improving the shelf life of the food after packaging and achieving better heat sealing quality.

[0027] In this embodiment, the driving member includes a first motor 35, a crank 31, a rocker 32 and a slider 34. The first motor 35 is mounted on the machine body, and the crank 31 is rotatably mounted on the machine body. The crank 31 can be connected to the rotating shaft of the first motor 35, and the rotation of the rotating shaft of the first motor 35 can drive the crank 31 to rotate. In addition, one end of the rocker 32 is hinged to the crank 31; the other end of the rocker 32 is hinged to the rolling member 20 through the connecting rod 33. One end of the slider 34 is hinged to the rocker 32, and the other end of the slider 34 is hinged to the first conveying assembly 10. The slider 34 can drive the first conveying assembly 10 to slide with the machine body when the rocker 32 rotates.

[0028] On the basis of this structure, the rotation of the rotating shaft of the first motor 35 can drive the crank 31 to rotate, and the rotation of the crank 31 can drive the rocker 32 to swing, and the swing of the rocker 32 can drive the slider 34 to rotate, and the rotation of the slider 34 can be limited by the sliding cooperation between the first conveying assembly 10 and the machine body, thereby driving the first conveying assembly 10 to move forward and backward on the machine body, approaching or moving away from the exhaust station on the machine body. At the same time, during the rotation of the rocker 32, the slider 34 can limit the rotation of the rocker 32, thereby guiding the connecting rod 33 hinged to the rocker 32 to swing, thereby driving the rolling element 20 to swing up and down, that is, the first motor 35 can drive the rolling element 20 to rotate up and down, and can also move forward and backward under the action of the connecting rod 33, and the same driving element can drive the first conveying assembly 10 and the rolling element 20 to move, saving driving force, and the first rolling element 20 and the first conveying assembly 10 move synchronously, and the follow-up rolling exhaust is performed while the follow-up output of the packaging bag is performed, and the action is more continuous.

[0029] Furthermore, the first conveying assembly 10 includes a conveying frame 11, a second motor 15, a conveying belt 12 and two conveying wheels 13. The second motor 15 is mounted on the machine body, and the conveying frame 11 is mounted on the machine body and can move close to or away from the exhaust station. The two conveying wheels 13 are rotatably mounted on both ends of the conveying frame 11, and the conveying belt 12 is wound around the two conveying wheels 13. Based on this structure, one end of the slider 34 is hinged to the rocker 32, and the other end of the slider 34 is hinged to the conveying frame 11; the conveying frame 11 is slidably matched with the machine body.

[0030] Thus, when the conveying action is performed, the rotation of the rotating shaft of the second motor 15 can drive one of the conveying wheels 13 to rotate, and the rotation of one of the conveying wheels 13 can drive the other conveying wheel 13 to rotate under the transmission action of the conveyor belt 12, thereby realizing the transmission of the conveyor belt 12. Of course, since the slider 34 is hinged on the rocker 32, and the other end of the slider 34 is hinged on the conveying frame 11, the slider 34 can guide the conveying frame 11 to reciprocate back and forth during the swinging of the rocker 32, so that the first conveying assembly 10 is close to or away from the above-mentioned exhaust station.

[0031] More specifically, the first conveying assembly 10 further includes a plurality of tensioning wheels 14, which are pivotally connected to the machine body, and the plurality of tensioning wheels 14 can be located below the conveying frame 11, so that when the conveyor belt 12 is installed, the conveyor belt 12 passes over the plurality of tensioning wheels 14 and is wound around the two conveying wheels 13, and the transmission section of the conveyor belt 12 between the two conveying wheels 13 forms a conveying section for receiving packaging bags. The tensioning wheels 14 can be wound around other parts of the conveyor belt 12 to tension the conveyor belt 12 to prevent the conveyor belt 12 from becoming loose.

[0032] Of course, the above-mentioned tensioning wheel 14 can be connected to the machine body through structures such as springs, so that the tensioning wheel 14 can maintain rotation close to the tensioning wheel 14 under the action of the spring. The tensioning wheel 14 can be close to the conveyor belt 12 after the conveyor belt 12 is relaxed, so that the conveyor belt 12 can always remain in a tensioned state.

[0033] Furthermore, the rolling member 20 includes a brush roller 22 and a brush roller driving member. The brush roller 22 is rotatably mounted on the connecting rod 33, and the brush roller driving member is used to drive the brush roller 22 to rotate. When the rolling action is performed, the brush roller 22 can be driven by the connecting rod 33 to approach the packaging bag, and the brush roller driving member drives the brush roller 22 to rotate, and the brush 21 on the brush roller 22 can roll the packaging bag, and the brush 21 is a flexible rolling force to avoid crushing the food in the packaging bag, and the rolling exhaust effect is better. In addition, when the brush roller 22 rotates, the contact surface between the brush 21 and the packaging bag can be larger during the rotation process, and the exhaust effect is better.

[0034] It should be noted that the rolling member 20 can also be implemented by other structures such as a rubber roller in the prior art. In short, any structure that can exert a flexible rolling force on the packaging bag can be used.

[0035] Embodiment 2,

[0036] like Figure 1 , Figure 2 as well as Figure 3 A finished product discharge conveying device shown includes a rolling exhaust device for a packaging machine, a second conveying component 40 and a hot pressing knife component. The rolling exhaust device for the packaging machine includes a body, a first conveying component 10, a rolling member 20 and a driving member. An exhaust station is provided on the body. The rolling member 20 is installed at the starting end of the first conveying component 10, and the driving member can drive the rolling member 20 to move close to the exhaust station. The rolling member 20 can also rotate close to the conveying end face of the first conveying component 10 during the process of moving close to the exhaust station. At the same time, the driving member is used to drive the first conveying component 10 to move close to or away from the exhaust station.

[0037] Specifically, the second conveying component 40 and the hot pressing knife component are both installed on the machine body, and the starting end of the first conveying component 10 is connected to the end of the second conveying component 40. The exhaust station is arranged on the first conveying component 10 and the second conveying component 40, and the hot pressing knife component is arranged above the exhaust station. The hot pressing knife component can move close to or away from the exhaust station.

[0038] On the basis of the above structure, when the finished product discharge conveying device of the present invention is used, the packaging bag on the packaging machine can be conveyed to the exhaust station via the second conveying component 40, and the hot pressing knife component can rotate close to the packaging bag at the exhaust station to perform heat sealing and cutting on the packaging bag to be packaged. During this process, the driving member can drive the rolling member 20 to move close to the exhaust station, close to the packaging bag to be heat sealed at the exhaust station, and at the same time, close to the conveying end surface of the first conveying component 10 to press downward on the packaging bag, so that the packaging bag can be rolled and exhausted. At the same time, the first conveying component 10 can move close to the second conveying component 40 during the follow-up rolling exhaust process, receive the exhausted and heat-sealed packaging bag for output, and after the rolling member 20 is exhausted, the amount of gas remaining after the heat sealing and cutting of the packaging bag can be reduced, thereby improving the shelf life of the food after packaging and achieving better heat sealing quality.

[0039] Furthermore, the first conveying assembly 10 includes a conveying frame 11, a second motor 15, a conveying belt 12 and two conveying wheels 13. The second motor 15 is mounted on the machine body, and the conveying frame 11 is mounted on the machine body and can move close to or away from the exhaust station. The two conveying wheels 13 are rotatably mounted on both ends of the conveying frame 11, and the conveying belt 12 is wound around the two conveying wheels 13. Based on this structure, one end of the slider 34 is hinged to the rocker 32, and the other end of the slider 34 is hinged to the conveying frame 11; the conveying frame 11 is slidably matched with the machine body.

[0040] Thus, when the conveying action is performed, the rotation of the rotating shaft of the second motor 15 can drive one of the conveying wheels 13 to rotate, and the rotation of one of the conveying wheels 13 can drive the other conveying wheel 13 to rotate under the transmission action of the conveyor belt 12, thereby realizing the transmission of the conveyor belt 12. Of course, since the slider 34 is hinged on the rocker 32, and the other end of the slider 34 is hinged on the conveying frame 11, the slider 34 can guide the conveying frame 11 to reciprocate back and forth during the swinging of the rocker 32, so that the first conveying assembly 10 is close to or away from the above-mentioned exhaust station.

[0041] More specifically, the first conveying assembly 10 further includes a plurality of tensioning wheels 14, which are pivotally connected to the machine body, and the plurality of tensioning wheels 14 can be located below the conveying frame 11, so that when the conveyor belt 12 is installed, the conveyor belt 12 passes over the plurality of tensioning wheels 14 and is wound around the two conveying wheels 13, and the transmission section of the conveyor belt 12 between the two conveying wheels 13 forms a conveying section for receiving packaging bags. The tensioning wheels 14 can be wound around other parts of the conveyor belt 12 to tension the conveyor belt 12 to prevent the conveyor belt 12 from becoming loose.

[0042] Of course, the above-mentioned tensioning wheel 14 can be connected to the machine body through structures such as springs, so that the tensioning wheel 14 can maintain rotation close to the tensioning wheel 14 under the action of the spring. The tensioning wheel 14 can be close to the conveyor belt 12 after the conveyor belt 12 is relaxed, so that the conveyor belt 12 can always remain in a tensioned state.

[0043] In the second aspect of the present invention, as a preferred embodiment, the second conveying assembly 40 has the same structure as the first conveying assembly 10, that is, the second conveying assembly 40 also includes a conveying frame 11, a second motor 15, a conveyor belt 12 and two conveying wheels 13. The second motor 15 is installed on the machine body, and the conveying frame 11 is installed on the machine body and can move close to or away from the exhaust station. The two conveying wheels 13 are rotatably installed on both ends of the conveying frame 11, and the conveyor belt 12 is wound around the two conveying wheels 13. Similarly, when conveying packaging bags, the packaging bags on the machine body can be placed on the conveyor belt 12 of the second conveying assembly 40, and the rotation of the second motor 15 of the second conveying assembly 40 can drive the conveying wheel 13 of the second conveying assembly 40 to rotate, thereby driving the conveyor belt 12 of the second conveying assembly 40 for transmission and transportation.

[0044] Furthermore, the rolling member 20 includes a brush roller 22 and a brush roller driving member. The brush roller 22 is rotatably mounted on the connecting rod 33, and the brush roller driving member is used to drive the brush roller 22 to rotate. When the rolling action is performed, the brush roller 22 can be driven by the connecting rod 33 to approach the packaging bag, and the brush roller driving member drives the brush roller 22 to rotate, and the brush 21 on the brush roller 22 can perform follow-up rolling on the packaging bag, and the brush 21 is a flexible rolling force to avoid crushing the food in the packaging bag, and the follow-up rolling exhaust effect is better. In addition, when the brush roller 22 rotates, the contact surface between the brush 21 and the packaging bag can be larger during the rotation process, and the exhaust effect is better.

[0045] In the second aspect of the present invention, as a preferred embodiment, the above-mentioned hot pressing knife assembly includes a mounting roller 52, a mounting roller driving member and a plurality of hot pressing knives 51. The mounting roller 52 is pivotally connected to the machine body, and the hot pressing knives 51 are all installed outside the mounting roller 52 and are distributed at intervals around the circumference of the central axis of the mounting roller 52. The mounting roller driving member is used to drive the mounting roller 52 to rotate.

[0046] Specifically, the above-mentioned installation roller driving member can be a third motor. The rotation of the rotating shaft of the third motor can drive the installation roller 52 to rotate. The rotation of the installation roller 52 can drive the hot pressing knife 51 distributed at intervals on the installation roller 52 to rotate to the exhaust station in sequence, and heat-seal and cut off the packaging bag at the conveying end of the second conveying assembly 40.

[0047] It should be noted that the hot pressing knife 51 can be selected as a heat sealing knife in the prior art, that is, the plastic packaging bag is cut by heat melting, and sealing can also be performed during the hot melting process.

[0048] More specifically, the hot pressing knife assembly may also include an elastic component 53, one end of the elastic component 53 is connected to the machine body, and the other end of the elastic component 53 is connected to the mounting roller 52, the elastic component 53 provides an elastic stress, and the elastic stress can drive the mounting roller 52 to approach the conveying end surface of the second conveying component 40. In this way, during the rotation of the mounting roller 52, the elastic stress provided by the elastic component 53 can drive the heat seal to move close to the conveying end surface of the second conveying component 40, maintain the state of heat sealing in contact with the packaging bag, and achieve a better heat sealing cutting effect.
