Description

Technical Field

[0001] The utility model relates to the technical field related to bag making, in particular to a bag body conveying mechanism of a bag making machine. Background Technique

[0002] Packaging bags are closely related to our lives. Packaging bags include non-woven bags, woven belts, plastic bags, etc. Taking non-woven bags as an example, non-woven bags have the characteristics of environmental protection and practicality, and have been vigorously promoted and used in recent years, which has promoted the rapid development of the fully automatic forming technology for non-woven bag making. However, with the development of non-woven fabrics in China in recent years, three-dimensional bags with stronger three-dimensional sense have become the mainstream of non-woven bags. The existing non-woven three-dimensional bags are formed by a three-dimensional bag forming machine in one processing. During the processing, a flat non-woven fabric needs to be pressed into a cuboid through a die lifting device. After the non-woven fabric is processed into a non-woven three-dimensional bag, in order to facilitate boxing and transportation, each three-dimensional bag needs to be flattened, sorted into piles and then packed and transported together.

[0003] The existing non-woven three-dimensional bag forming machines usually are provided with a bag folding machine to fold and flatten the formed three-dimensional bags. After the non-woven three-dimensional bags are folded and flattened, subsequent conveying and bag sorting work still needs to be carried out. In the prior art, a transmission mechanism is provided to convey the non-woven bags to the bag sorting mechanism for bag sorting. The output end of the transmission mechanism is located above the bag sorting mechanism, and the non-woven bags are dropped into the bag sorting mechanism for bag sorting by the way of falling. The transmission mechanism conveys according to the set path and direction, so the falling height is fixed. However, with the development of the prior art, non-woven bag making machines can replace the dies and produce non-woven bags of different sizes. When different sizes of non-woven bags are conveyed through the transmission mechanism after being folded, when they are dropped and conveyed to the bag sorting mechanism, because the height of the transmission mechanism is fixed, when conveying smaller non-woven bags, there is a problem that the falling height is too high, resulting in the inclination of the bag body after falling. When conveying larger non-woven bags, there will be a problem that the falling height is too low, resulting in interference between the bag body and the transmission mechanism after falling, thereby interfering with the bag sorting efficiency.

[0004] Therefore, in the prior art, the transmission mechanism in the non-woven bag forming machine has the problems that the falling height cannot be adjusted, resulting in inconvenient bag sorting and poor bag sorting efficiency when producing non-woven bags of different sizes. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art that the falling height of the transmission mechanism in the non-woven bag forming machine cannot be adjusted, resulting in inconvenient bag sorting and poor bag sorting efficiency when producing non-woven bags of different sizes.

[0006] To solve the above technical problems, an embodiment of the present utility model discloses a bag body conveying mechanism of a bag making machine. The bag body conveying mechanism is arranged in the bag body conveying channel of the bag making machine and located between two adjacent workstations. The bag body conveying channel between two adjacent workstations includes an input conveying section and an output conveying section. The input conveying section is located on the side close to the upstream workstation in the bag body conveying direction of the bag body, and the input end is communicated with the output end of the upstream workstation. The output conveying section is located on the downstream side of the input conveying section in the bag body conveying direction. The input end of the output conveying section is communicated with the output end of the input conveying section, and the output end is communicated with the input end of the downstream workstation.

[0007] The output end of the output conveying section can be switched between a locked state and an adjusted state. When the output end of the output conveying section is in the adjusted state, the length of the output conveying section facing the downstream workstation can be adjusted, so as to adjust the bag body conveying distance between the output end of the output conveying section and the input end of the downstream workstation.

[0008] When looking at the bag body conveying mechanism from one side of the bag body conveying mechanism, the bag body conveying direction of one of the input conveying section and the output conveying section is the horizontal direction, and the bag body conveying direction of the other is inclined and extends relative to the horizontal direction.

[0009] By adopting the above technical solution, a bag body conveying mechanism is provided to convey the bag body from one workstation to another workstation, realizing the continuous transmission of the bag body.

[0010] Furthermore, one of the input conveying section and the output conveying section is in the horizontal direction, and the other is in the inclined direction. During the process of conveying the bag body, the conveying direction of the bag body is changed, which is more convenient for the subsequent workstation to process. In summary, the bag body conveying mechanism of the bag making machine disclosed in this application can improve the production efficiency.

The output adjustment roller is rotatably arranged in the adjustment groove, and the output adjustment roller can be switched between a locked state and an adjustment state. When the output adjustment roller is in the adjustment state, the output adjustment roller can be movably adjusted along the length direction of the adjustment groove.

[0014] With the above technical solution, by setting the output adjustment roller and the adjustment groove, the adjustment setting of the output end of the output transfer section can be realized through a simple structure, which has the advantages of simple structure, convenient and reliable adjustment. Moreover, through the adjustment of the adjustment roller, the length of the conveyor belt can be quickly adjusted according to the actual production requirements to adapt to the conveying of materials of different sizes and batches, improving the flexibility of the production line.

The input direction of the input conveying section is horizontal and the output direction is vertical. Moreover, through such a setting method, the transmission height of the output conveying section is higher than the input direction, which is convenient for the bag to fall in a free-fall manner along the vertical direction. And this layout has high flexibility, can optimize the layout of the production line and reduce space waste. Especially, it is convenient for the bag to fall and perform bag sorting operations. And the conveying paths of the first turning section and the second turning section are both curved, which can further improve the flatness of the bag during the bag transmission process.

[0065] Packaging bags are closely related to our lives. Common packaging bags include non-woven bags, woven belts, plastic bags, etc. Taking non-woven bags as an example, non-woven bags have the characteristics of environmental protection and practicality, and have been vigorously promoted and used in recent years. Taking a non-woven bag making machine as an example, existing non-woven bag making machines generally include multiple stations such as edge ironing, forming, bag folding, and bag aligning. Finally, the folded and sorted non-woven bags can be output for subsequent storage, transportation, and use.

[0066] During the production process of non-woven bags, the entire production line requires conveyor belts to transfer non-woven fabrics or bag bodies, so as to transfer non-woven fabrics or bag bodies from the previous station to the next station, which has the advantage of high transfer efficiency.

[0067] Taking the two stations of bag folding and bag sorting of non-woven bags as an example, the bag folding mechanism is arranged upstream of the bag sorting mechanism. After the non-woven three-dimensional bags of the model are folded and flattened in the bag folding mechanism, they are continuously conveyed to the bag sorting mechanism for bag sorting. However, most of the existing common bag folding machines are arranged horizontally, while the bag sorting mechanism is generally a vertical bag sorting machine, that is, the packaging bag needs to be changed from a horizontal state to a vertical state during the conveying process, and when the non-woven bags are conveyed to the bag sorting mechanism for bag sorting, the output end of the transmission mechanism is located above the bag sorting mechanism, and the non-woven bags are dropped into the bag sorting mechanism by vertical dropping. The transmission mechanism is used to transport the bags according to the set path and direction, so the bag drop height is fixed. However, with the development of existing technologies, non-woven bag making machines can replace molds and produce non-woven bags of different sizes. However, the height of common transmission mechanisms is fixed, and the effect is best only when non-woven bags of fixed models and sizes are transmitted. When smaller non-woven bags are transmitted, the bag drop height is too high, resulting in the bag body tilting after the bag is dropped. When larger non-woven bags are transmitted, the bag drop height is too low, resulting in the bag body interfering with the transmission mechanism after the bag is dropped.

[0068] For example, in a transmission mechanism that has been set up, the bag drop height between the output end of the transmission mechanism and the bag drop platform of the bag sorting mechanism is set to 50cm, and the length of the produced non-woven bag is 40cm. In this case, the non-woven bag can fall smoothly without interfering with the transmission mechanism. However, when the length of the produced non-woven bag is 30cm, the bag drop height of the non-woven bag is too high, and the non-woven bag is prone to tipping or unstable bag drop when it falls from the output end to the bag drop platform. When the length of the produced non-woven bag is 50cm, the bag drop height of the non-woven bag is too low, which may interfere with the transmission mechanism and thus affect the bag sorting efficiency.

[0069] Therefore, the transmission mechanism in the non-woven bag forming machine in the prior art has the problem that the bag dropping height cannot be adjusted, resulting in inconvenient bag sorting and poor bag sorting efficiency when producing non-woven bags of different sizes. In order to solve the above technical problems, the bag body transmission mechanism of the bag making machine disclosed in this application is intended to achieve the height adjustment between the output end of the transmission mechanism and the bag sorting device by setting the output end of the transmission mechanism to be adjustable in length. When replacing non-woven bags of different sizes, the height of the output end of the transmission mechanism can be adjusted according to needs, thereby ensuring the transmission and bag sorting effect of the non-woven bags.

[0070] Next, the bag body conveying mechanism of the bag making machine disclosed in the utility model is described in detail:

[0071] The implementation mode of this embodiment discloses a bag body conveying mechanism of a bag making machine. The bag body conveying mechanism is arranged in the bag body conveying channel 100 of the bag making machine and is located between two adjacent workstations. Please refer to Figure 1 , in one implementation, the bag body conveying channel 100 between two adjacent workstations includes an input conveying section 110 and an output conveying section 120. The input conveying section 110 is located on the side close to the upstream workstation in the bag body conveying direction of the bag body, and the input end is communicated with the output end of the upstream workstation. The output conveying section 120 is located on the downstream side of the input conveying section 110 in the bag body conveying direction. The input end of the output conveying section 120 is communicated with the output end of the input conveying section 110, and the output end is communicated with the input end of the downstream workstation.

[0072] The output end of the output conveying section 120 can be switched between a locked state and an adjusted state. When the output end of the output conveying section 120 is in the adjusted state, the length of the output conveying section 120 facing the downstream workstation can be adjusted, so as to adjust the bag body conveying distance between the output end of the output conveying section 120 and the input end of the downstream workstation. The bag body conveying channel 100 is as Figure 1 shown by the thick line.

[0073] When looking at the bag body conveying mechanism from one side of the bag body conveying mechanism, the bag body conveying direction of one of the input conveying section 110 and the output conveying section 120 is the horizontal direction, and the bag body conveying direction of the other is inclined and extends relative to the horizontal direction.

[0074] First of all, it should be noted that the bag body conveying mechanism of the bag making machine disclosed in this embodiment includes but is not limited to being applied to non-woven bag making machines, and can also be applied to different models such as paper bag making machines and plastic bag making machines. And this conveying mechanism includes but is not limited to being arranged between the bag folding workstation and the bag arranging workstation, and can also be arranged between, for example, the forming workstation and the bag folding workstation, and between the raw material workstation and the forming workstation according to actual needs. Those skilled in the art can design and adjust according to actual needs, and this embodiment does not make specific limitations.

[0075] Furthermore, it can be that the bag body conveying direction of the input conveying section 110 is the horizontal direction, and the bag body conveying direction of the output conveying section 120 extends obliquely downward relative to the horizontal direction, or it can be that the bag body conveying direction of the input conveying section 110 is the vertical direction, and the bag body conveying direction of the output conveying section 120 is the horizontal direction. This embodiment does not make specific limitations.

[0076] Taking the bag body conveying direction of the input conveying section 110 as the horizontal direction, the bag body conveying direction of the output conveying section 120 extending obliquely downward relative to the horizontal direction, and the downstream workstation of the output conveying section 120 being the bag arranging mechanism 700 as an example for illustration:

[0077] The output end of the output conveyor section 120 can be switched between a locked state and an adjustment state. For example, in the initial setting state, the height between the output end of the output conveyor section 120 and the bag dropping platform of the bag arranging mechanism 700 is 40 cm. At this time, when producing bag bodies with a production length between 30 and 35 cm, they can all fall smoothly from the output end onto the bag dropping platform, and the output end is in the locked state at this time. When the model of the bag body to be produced becomes smaller and the length of the bag body to be produced is between 25 and 30 cm, the originally high height between the output end and the bag dropping platform of the bag arranging mechanism 700 will cause problems such as unstable bag dropping and affecting the bag arranging effect. At this time, the output end is adjusted to the adjustment state, and the length of the output end facing the downstream station is adjusted to become longer, so that the height between the output end of the output conveyor section 120 and the bag dropping platform of the bag arranging mechanism 700 is reduced to 35 cm. Then, the output end is adjusted to the locked state to carry out the production and manufacturing process of the bag body, avoiding the problem of unstable bag dropping. When the model of the bag body to be produced becomes larger and the length of the bag body to be produced is between 40 and 45 cm, the originally low height between the output end and the bag dropping platform of the bag arranging mechanism 700 will cause problems such as interference between the bag body and the output end during bag dropping. At this time, the output end is adjusted to the adjustment state, and the length of the output end facing the downstream station is adjusted to become shorter, so that the height between the output end of the output conveyor section 120 and the bag dropping platform of the bag arranging mechanism 700 is increased to 50 cm, avoiding interference between the bag body and the output end during bag dropping.

[0078] Furthermore, the output end of the output conveyor section 120 can be switched between the locked state and the adjustment state through various different methods or structures. For example, it can be achieved through automatic adjustment or manual adjustment. When adjusting manually, an adjustment slot 210 or an adjustment guide rail can be provided on the frame 200 in the height direction, and an adjustment bolt or an adjustment slider is provided. The adjustment bolt and the adjustment slider can be switched between the locked state and the adjustment state. When set to the adjustment state, the adjustment bolt or the adjustment slider can be adjusted relative to the adjustment slot 210 or the adjustment guide rail, and the height can be adjusted and locked. When adjusting automatically, it can be achieved by setting an air pump and an adjustment rod, or by setting an electric telescopic rod, or by using a driving motor plus a gear and rack mechanism, a worm and gear mechanism, a conveyor belt mechanism, a lead screw mechanism, etc. As long as the output conveyor section 120 can be moved and adjusted and the state can be switched, this embodiment does not make specific limitations.

[0079] Through the design of this structure, a bag body conveying mechanism is set to convey the bag body from one station to another station, realizing the continuous transmission of the bag body. Moreover, in this application, the output end of the output conveying section 120 is set to be switchable between a locked state and an adjustable state, so as to adjust the distance between the output end and the input end of the downstream station according to different requirements. For example, the bag dropping height is adjusted according to bags of different sizes, thereby improving the bag sorting efficiency when producing non-woven bags of different sizes.

[0080] Furthermore, one of the input conveying section 110 and the output conveying section 120 is in the horizontal direction, and the other is in the inclined direction. During the transmission of the bag body, the transmission direction of the bag body is changed, which is more convenient for the subsequent station to process. In summary, the bag body conveying mechanism of the bag making machine disclosed in this application can improve production efficiency. By adjusting the conveying mechanism, the precise position of the bag body on the production line can be ensured. When the production requirements change, the conveying mechanism can be adjusted relatively easily, is easy to adjust, and can adapt to various bag types of different sizes.

[0081] An embodiment of the present utility model discloses a bag body conveying mechanism of a bag making machine. The bag body conveying direction of the input conveying section 110 is in the horizontal direction, and the bag body conveying direction of the output conveying section 120 extends obliquely downward from its input end to the output end, and the included angle with the horizontal direction is within the range of 90° to 160°.

[0082] With the design of this structure, the included angle between the bag body conveying directions of the input conveying section 110 and the output conveying section 120 is also equal to the direction change of the bag body during the transmission. Therefore, the transmission direction of the bag body can be adjusted according to requirements, and it can adapt to various bag types and is easy to adjust.

[0083] For example, when the included angle between the bag body conveying direction of the output conveying section 120 and the bag body conveying direction of the input conveying section 110 is 90°, the bag body conveying direction of the input conveying section 110 is in the horizontal direction, and the output conveying section 120 is in the vertically downward direction; when the included angle between the bag body conveying direction of the output conveying section 120 and the bag body conveying direction of the input conveying section 110 is 95°, 100°, 120°, 160° or other angles, the bag body conveying direction of the input conveying section 110 is in the horizontal direction, and the output conveying section 120 is in the obliquely downward direction. Those skilled in the art can adjust and design according to actual requirements, and this embodiment does not make specific limitations thereto.

[0084] An embodiment of this embodiment also discloses a bag body conveying mechanism of a bag making machine. A machine frame 200 is provided on one side of the conveying mechanism (the machine frame 200 can be referred to Figure 4 ) See Figure 1 And Figure 2In two different implementation manners, at least one output adjusting roller 121 is provided at the output end of the output conveying section 120, and an adjusting groove 210 adapted to the output adjusting roller 121 is provided on the frame 200. The output adjusting roller 121 is rotatably arranged in the adjusting groove 210. The output adjusting roller 121 can be switched between a locked state and an adjusting state. When the output adjusting roller 121 is in the adjusting state, the output adjusting roller 121 can be movably adjusted along the length direction of the adjusting groove 210.

[0085] Specifically, in this embodiment, the adjusting groove 210 and the output adjusting roller 121 can be designed according to actual requirements. The length of the adjusting groove 210 is greater than or equal to the adjusting length of the output conveying section 120. For example, when the adjusting groove 210 is set to be 20 cm long, the adjusting length is 20 cm or less than 20 cm. When the adjusting groove 210 is set to be 15 cm long, the adjusting length is 15 cm or less than 15 cm. When the adjusting groove 210 is set to be 30 cm long, the adjusting length is 30 cm or less than 30 cm. Those skilled in the art can adjust and design according to actual requirements, and this embodiment does not make specific limitations. The output adjusting roller 121 can be controlled by a hand-tightening nut, an adjusting pin, a motor, an air pump, etc. to realize the switching between the adjusting state and the locked state.

[0086] By adopting the above technical solution, by setting the output adjusting roller 121 and the adjusting groove 210, the adjustment setting of the output end of the output conveying section 120 can be realized through a simple structure, which has the advantages of simple structure, convenient and reliable adjustment. Moreover, through the adjustment of the adjusting roller, the length of the conveyor belt can be quickly adjusted according to actual production requirements to adapt to the conveying of materials of different sizes and batches, improving the flexibility of the production line. The setting of the adjusting roller can adjust the conveyor belt length according to the actual conveying speed and distance of the materials, reduce the waiting time, improve the conveying efficiency, and at the same time reduce the maintenance cost and improve the production safety.

[0087] The embodiment of the present utility model discloses a bag body conveying mechanism of a bag making machine. The adjusting groove 210 includes but is not limited to the following three setting manners:

[0088] The adjusting groove 210 includes a vertically extending groove provided on the frame 200, and the vertically extending groove extends along the height direction of the frame 200. Alternatively, the adjusting groove 210 includes an inclined extending groove provided on the frame 200, and an included angle is formed between the extending direction of the inclined extending groove and the conveying direction of the output conveying section 120. Alternatively, the adjusting groove 210 includes an arc-shaped extending groove provided on the frame 200, and the arc-shaped extending groove extends along an arc shape on the frame 200.

[0089] Specifically, when the adjustment slot 210 is set as a vertically extending slot, the length of the vertically extending slot is equal to the adjustment length of the output conveying section 120. When it is set as an inclined extending slot, the length of the vertically extending slot is greater than the adjustment length of the output conveying section 120 and can adjust the position while adjusting the height. When it is set as an arc-shaped extending slot, the adjustment is relatively linear and the position can also be adjusted.

[0090] With the design of this structure, when the vertical slot is set, the length of the output conveying section 120 facing the downstream station can be conveniently adjusted. When it is set as an inclined extending slot or an arc-shaped extending slot, the height of the output conveying section 120 can be adjusted, and at the same time, the angle of the output conveying section 120 can also be adjusted.

[0091] The implementation manner of this embodiment also discloses a bag body conveying mechanism of a bag making machine. Please refer to Figure 2 and Figure 3 a specific implementation manner shown in. The conveying channel 100 further includes a first turning section 130, an intermediate conveying section 140, and a second turning section 150 that are sequentially connected. Along the bag body conveying direction, the first turning section 130, the intermediate conveying section 140, and the second turning section 150 are sequentially arranged downstream of the input conveying section 110 and upstream of the output conveying section 120.

[0092] The first turning section 130 is located between the input conveying section 110 and the intermediate conveying section 140, and the included angle between the bag body conveying directions of the input conveying section 110 and the intermediate conveying section 140 is adjustable.

[0093] The second turning section 150 is located between the intermediate conveying section 140 and the output conveying section 120, and the included angle between the bag body conveying directions of the intermediate conveying section 140 and the output conveying section 120 is adjustable.

[0094] The conveying paths of the first turning section 130 and the second turning section 150 are both curved, and the turning radius of the second turning section 150 is greater than the turning radius of the first turning section 130.

[0095] Specifically, in this embodiment, the included angle between the bag conveying direction of the input conveying section 110 and the bag conveying direction of the middle conveying section 140 can be adjusted between 90° and 120°, for example, it can be 90°, 100°, 120°, etc. The included angle between the bag conveying direction of the middle conveying section 140 and the bag conveying direction of the output conveying section 120 can be adjusted between 0° and 60°, for example, it can be 0°, 10°, 30°, 60°, etc. When the included angle between the bag conveying direction of the middle conveying section 140 and the bag conveying direction of the output conveying section 120 is 0°, the bag conveying direction changes from vertically upward to vertically downward. Further, for example, the conveying paths of the first turning section 130 and the second turning section 150 are both set to be semi-circular. The turning radius of the second turning section 150 can be 10 - 20 cm greater than the turning radius of the first turning section 130, for example, 10 cm, 15 cm, 20 cm, etc. This embodiment does not make specific limitations on this.

[0096] Through the design of this structure, in this application, by arranging the input conveying section 110, the first turning section 130, the middle conveying section 140, the second turning section 150, and the output conveying section 120 that are sequentially connected, the input direction of the input conveying section 110 is the horizontal direction, and the output direction is the vertical direction, which can realize the turning transmission of the bag. And, through such a setting method, the transmission height of the output conveying section 120 is higher than the input direction, which is convenient for the bag to fall in a free-fall manner along the vertical direction. And this layout has high flexibility, can optimize the layout of the production line, and reduce space waste. Especially, it is convenient for the bag to fall and perform bag arranging operations. And the conveying paths of the first turning section 130 and the second turning section 150 are both curved, which can further improve the flatness of the bag during the bag transmission process. Setting the curved conveying path design can reduce the friction and collision of the bag during the conveying process, thereby reducing the breakage rate and ensuring product quality.

[0097] For further reference, please see Figure 2 and Figure 3 , in one preferred implementation, at the position where the first turning section 130 is located, a first turning roller 131 is provided. The first turning roller 131 is rotatably provided on the frame 200. A first driving assembly is provided on one side of the first turning roller 131, and the first driving assembly is in transmission connection with the first turning roller 131.

[0098] At the position where the second turning section 150 is located, a second turning roller 151 is provided. The second turning roller 151 is rotatably provided on the frame 200. A second driving assembly 152 is provided on one side of the second turning roller 151, and the second driving assembly 152 is in transmission connection with the second turning roller 151. And, the diameter size of the second turning roller 151 is larger than the diameter size of the first turning roller 131.

[0099] The diameter of the second turning roller 151 is 20 - 30 cm larger than that of the first turning roller 131, such as 20 cm, 25 cm, 30 cm, etc. With this structural design, by setting the turning rollers, the transmission of the bag can be achieved with a simple structure.

[0100] In another implementation, a first turning roller assembly is provided at the position where the first turning section 130 is located. The first turning roller assembly is rotatably provided on the frame 200. The first turning roller assembly includes at least three first turning rollers, and the at least three first turning rollers are distributed in a "pin" shape. A first driving assembly is provided on one side of the first turning roller assembly, and the first driving assembly is in transmission connection with one of the first turning rollers.

[0101] A second turning roller assembly is provided at the position where the second turning section 150 is located. The second turning roller assembly is rotatably provided on the frame 200. The second turning roller assembly includes at least three second turning rollers, and the at least three second turning rollers are distributed in a "pin" shape. A second driving assembly is provided on one side of the second turning roller assembly, and the second driving assembly is in transmission connection with one of the second turning rollers. It should be noted that because the turning angle of the second turning section is small, the three second turning rollers are arranged in sequence along the arc direction.

[0102] With this structural design, the three first turning rollers are distributed in a "pin" shape, and the three first turning rollers are distributed in a "pin" shape, which can reduce the structural volume while ensuring the transmission and turning of the bag.

[0103] More specifically, for example, in one implementation, the first turning roller assembly includes three first turning rollers, and the three first turning rollers are distributed in a "pin" shape. And the diameter of the first turning roller located above the other two first turning rollers in height among the three first turning rollers is larger. The function of this setting is that the first turning roller with a larger diameter above can provide a larger turning contact area, and make the arc of the turning path larger, making the turning path more inclined to be circular arc-shaped, which is more conducive to the transmission and turning of the bag.

[0104] In another implementation, the first turning roller assembly includes 6 first turning rollers, and the 6 first turning rollers are arranged at intervals in sequence and finally present a semi-circular arc shape. Similarly, it is ensured that when the conveyor belt is wound around the 6 first turning rollers, there is a larger turning contact area, making the arc of the turning path larger and more inclined to be circular arc-shaped, and also more conducive to the transmission and turning of the bag, and avoiding problems such as wrinkles on the bag.

[0105] The implementation mode of this embodiment also discloses a bag body conveying mechanism of a bag making machine. The bag body conveying mechanism includes a first conveying component 300 and a second conveying component 400. The first conveying component 300 includes a first conveyor belt 310 and a plurality of first rotating components. The first conveyor belt 310 is wound around a plurality of first rotating components; the second conveying component 400 includes a second conveyor belt 410 and a plurality of second rotating components. The second conveyor belt 410 is wound around a plurality of second rotating components.

[0106] The plurality of first rotating components include a first input end rotating roller 320 arranged at the first input section 110, a first turning rotating roller 131 arranged at the first turning section 130, a first output rotating roller 330 arranged at the output conveying section 120, and further include a plurality of first driven rollers 340 arranged at intervals. The first conveyor belt 310 sequentially winds around the first input end rotating roller 320, the first turning rotating roller 131 group, a plurality of first driven rollers 340, and the first output rotating roller 330.

[0107] The plurality of second rotating components include a second input end rotating roller 420 arranged at the first input section 110, a second turning rotating roller 151 arranged at the second turning section 150, a second output rotating roller 430 arranged at the output conveying section 120, and further include a plurality of second driven rollers 440 arranged at intervals. The second conveyor belt 410 sequentially winds around the second input end rotating roller 420, the second turning rotating roller 151 group, a plurality of second driven rollers 440, and the second output rotating roller 430.

[0108] With this structural design, the transmission of the bag body can be realized through the cooperation of two conveyor belts and rotating rollers, and the setting of a plurality of rotating rollers can make the conveyor belt have better flatness, so that the conveyor belt can stably convey the bag body, which has the advantage of simple structure.

[0109] The implementation mode of this embodiment also discloses a bag body conveying mechanism of a bag making machine. At the output conveying section 120 of the conveying mechanism, along the height direction, the second output rotating roller 430 is lower than the first output rotating roller 330, and a bag dropping height difference is formed between the bottom ends of the first conveyor belt 310 and the second conveyor belt 410. Moreover, the width dimensions of the first conveyor belt 310 and the second conveyor belt 410 are the same, and the width dimensions of the first conveyor belt 310 and the second conveyor belt 410 are greater than the width dimension of the bag body.

[0110] Specifically, in this embodiment, the second output rotating roller 430 can be set to be 5 - 15 cm lower than the first output rotating roller 330, such as 5 cm, 10 cm, 15 cm, etc. The width dimensions of the first conveyor belt 310 and the second conveyor belt 410 can be 10 - 20 cm greater than the width dimension of the bag body, such as 10 cm, 15 cm, 20 cm, etc. This embodiment does not make specific limitations on this.

[0111] With this structural design, a bag-falling height difference is formed between the bottom end of the first conveyor belt 310 and the bottom end of the second conveyor belt 410, which is more convenient for the bag body to separate and fall, avoiding the bag body being rolled away by the conveyor belt. A bag-falling height difference is formed between the bottom end of the first conveyor belt 310 and the bottom end of the second conveyor belt 410, which can adapt to and match non-woven bags of different sizes.

[0112] An embodiment of the present utility model also discloses a bag body conveying mechanism of a bag making machine. In the input conveying section 110 of the conveying mechanism, the first conveying component 300 is located above the second conveying component 400, and an auxiliary winding part is arranged at the front end of the first conveyor belt 310. The auxiliary winding part includes two auxiliary winding rollers 500 arranged at intervals, and an auxiliary winding member 510 is wound around the two auxiliary winding rollers 500. Among them, the auxiliary winding member 510 includes any one of a conveyor belt, an elastic belt, and a spring.

[0113] With this structural design, the auxiliary winding part is provided, which is more convenient for the bag body to enter the input conveying section 110, improves the automation level and production efficiency, and reduces the friction force during the bag body transmission, so that the bag body can be evenly transmitted.

[0114] More specifically, a tension roller 450 and a regulator 460 are also arranged in the bag body conveying mechanism. The tension roller 450 can adjust the tension of the conveyor belt, and the regulator 460 can adjust the gap between the two conveyor belts in contact.

[0115] In this embodiment, please refer to Figure 4 , two adjacent workstations include a bag folding mechanism 600 and a bag arranging mechanism 700. The input end of the bag body conveying mechanism is communicated with the output end of the bag folding mechanism 600, and the output end of the bag body conveying mechanism is communicated with the input end of the bag arranging mechanism 700; and, along the height direction of the frame 200, the bag arranging mechanism 700 is located below the output end of the bag body conveying mechanism.

[0116] The bag folding mechanism 600 includes a bag folding frame 200, two groups of bag folding conveyor belts arranged on the bag folding frame 200. The two groups of bag folding conveyor belts form a "V"-shaped bag folding channel along the bag body conveying direction. Side insertion plates that can be adjusted are also arranged on both sides in the width direction of the bag folding conveyor belt; the side insertion plates gradually penetrate into the bag folding channel along the bag body conveying direction and form insertion edges; and, a bottom folding hook is also included. The bottom folding hook is arranged on both sides in the width direction of the bag folding conveyor belt, and the bottom folding hook partially penetrates into the bag folding channel to perform edge folding on the bottom of the bag body.

[0117] The bag arranging mechanism 700 is located vertically below the output end; among them, the bag arranging mechanism 700 includes a bag dropping pedestal, a bag pushing assembly, and a bag blocking assembly. The bag dropping pedestal is directly below the output end. A bag arranging space is formed among the bag dropping pedestal, the bag blocking assembly, and the bag pushing assembly. The bag body drops onto the bag dropping pedestal of the bag arranging mechanism along the output direction, and the bag pushing assembly can reciprocate within the bag arranging space.

[0118] In summary, the present utility model provides a bag body conveying mechanism of a bag making machine. The bag body conveying mechanism is arranged in the bag body conveying channel 100 of the bag making machine and is located between two adjacent workstations. The bag body conveying channel 100 includes an input conveying section 110, a first turning section 130, an intermediate conveying section 140, a second turning section 150, and an output conveying section 120, such that the conveying height of the output conveying section 120 is higher than the input direction, facilitating the bag body to drop in a free-fall manner along the vertical direction. In particular, it is convenient for the bag body to drop and perform operations at subsequent workstations. And in this application, by setting the output end of the output conveying section 120 to be switchable between a locked state and an adjusted state, the distance between the output end and the input end of the downstream workstation can be adjusted according to different requirements. For example, the bag dropping height can be adjusted according to different sizes of bag bodies, thereby improving the bag arranging efficiency when producing non-woven bags of different sizes. The bag body conveying mechanism of the bag making machine disclosed in this application can improve production efficiency. By adjusting the conveying mechanism, the precise position of the bag body on the production line can be ensured. When production requirements change, the conveying mechanism can be relatively easily adjusted, is easy to adjust, and can adapt to various bag types of different sizes. And the design of the curved conveying path in the first turning section 130 and the second turning section 150 can reduce the friction and collision of the bag body during the conveying process, thereby reducing the breakage rate and ensuring product quality.

[0119] Finally, a brief description is given to the bag body conveying path in the bag body conveying mechanism of the bag making machine disclosed in this embodiment:

[0120] The formed three-dimensional bag body is first folded in the bag folding mechanism 600, and then enters from the input conveying section 110 of the bag body conveying mechanism. The direction of entering the input conveying section 110 is the horizontal direction. Then, through the first turning section 130, the conveying direction of the bag body changes from the horizontal direction to the vertical upward conveying. Then, it is conveyed through the vertically upward intermediate conveying section 140 to the second turning section 150. The second turning section 150 changes the conveying direction of the bag body again, making the conveying direction of the bag body change from the vertical upward to the vertical downward conveying. Finally, after passing through the output conveying section 120, it falls into the bag arranging mechanism 700. The bag body conveying mechanism disclosed in this application changes the conveying direction of the bag body twice, from the horizontal direction to the vertical downward direction. While connecting and communicating the bag folding mechanism 600 and the bag arranging mechanism 700, it also raises the bag body output direction, that is, while realizing the turning, it also increases the bag dropping height, thereby facilitating the bag body to fall into the bag arranging mechanism 700 for bag arranging processing.
