It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the concept of these exemplary embodiments to those of ordinary skill in the art.

[0077] The present invention provides an automatic bag folding machine 100 for linked bags, which can automatically fold various linked bags of varying numbers and sizes, and the folded linked bags can automatically enter a material box 103. It should be noted that the linked bags herein refer to strip bags formed by a plurality of independent bags connected in sequence. The quality, quantity, size, etc. of the linked bags are not restricted, and even linked bags of relatively light weight can be folded. Moreover, the hardness of the indentations between adjacent bags is not restricted, and even linked bags with relatively soft or relatively hard indentations can be folded. For the sake of brevity, the automatic bag folding machine 100 for linked bags is replaced by a bag folding machine below.

[0078] like Figure 1 to Figure 2 As shown, the bag folding machine 100 may include a support 101, a bag conveyor belt 102 and a folding mechanism. Figure 3 and Figure 4 As shown, the bag folding machine 100 also includes a material box 103 and a control device. The bag conveyor belt 102 and the folding mechanism can be arranged on the bracket 101 and supported by the bracket 101. The bag conveyor belt 102 is arranged obliquely, specifically extending obliquely upward from its feed end to its discharge end. A discharge belt 104 can be provided upstream of the feed end of the bag conveyor belt 102. At least a part of the bag can be placed on the discharge belt 104 first, and then gradually transported to the bag conveyor belt 102. The folding mechanism can be arranged on the side where the discharge end of the bag conveyor belt 102 is located, and receive the bag. The material box 103 is arranged below the folding mechanism, for receiving the folded bag. The control device can control the operation of each device, component and part of the bag folding machine 100.

[0079] The folding mechanism is used to fold the connected bag. Specifically, Figure 3 and Figure 4 As shown, the folding mechanism may include a material sorting component 110 and a folding component 120. The material sorting component 110 is arranged on the upper side of the folding component 120. Further, the material sorting component 110 is located on the side where the discharge end of the bag conveyor belt 102 is located, and the folding component 120 is located on the outlet side of the material sorting component 110. The material sorting component 110 can perform operations such as compacting and leveling the conveyed bag, so that the bag can be folded more easily. The folding component 120 can fold the leveled bag. The folded bag can automatically enter the material box 103 in sequence.

[0080] like Figure 5As shown, the material sorting component 110 can be configured to have a material sorting channel P1 for clamping the connected bags and conveying the connected bags downward. The folding component 120 can be configured to have a conveying channel P2 for clamping the connected bags and conveying the connected bags downward, and the conveying channel P2 can swing to fold the connected bags. The material sorting channel P1 can be located on the inlet side of the conveying channel P2. The connected bags from the continuous bag conveyor belt 102 first enter the material sorting channel P1, and can be pressed, leveled, etc. by the clamping action of the material receiving channel P1. Then they enter the conveying channel P2, are conveyed downward smoothly by the clamping action of the conveying channel P2, and the connected bags are folded under the action of the swing.

[0081] Specifically, the material sorting assembly 110 may include a drive shaft 111, a first material sorting belt 112, and a second material sorting belt 113. The drive shaft 111 can rotate around its own drive axis. In the illustrated embodiment, the inlet end of the first material sorting belt 112 can be arranged on the drive shaft 111, and is kept in operation by the driving action of the drive shaft 111. The drive shaft 111 provides driving force to the first material sorting belt 112. The second material sorting belt 113 can be arranged on the upper side of the first material sorting belt 112. A material sorting channel P1 can be formed between the first material sorting belt 112 and the second material sorting belt 113. When the first material sorting belt 112 is in operation, it drives the connecting bag to move together, and the second material sorting belt 113 is passively driven by the first material sorting belt 112 through the connecting bag to keep in operation.

[0082] In this embodiment, the first material stripping belt 112 is an active belt, and the second material stripping belt 113 is a passive belt. Of course, if necessary and / or desired, the drive shaft 111 can be used to drive the second material stripping belt 113, in which case the second material stripping belt 113 is an active belt and the first material stripping belt 112 is a passive belt.

[0083] The material sorting component 110 provided in this embodiment can provide a smooth and automatically pulled material sorting channel P1, which can not only keep the connected bags in a compressed and flat state to avoid accumulation and jamming of the connected bags during the transmission process; but also can adjust the transmission speed of the connected bags by adjusting the speed of the material sorting belt to meet the needs of various connected bags with different single bag lengths, as well as meet the needs of folding different numbers of single bags in a connected bag at one time, thereby improving the working efficiency of the bag folding machine 100.

[0084] The folding assembly 120 may include a swing shaft 121, a swing frame 122, a first conveyor belt 123, and a second conveyor belt 124. The swing shaft 121 can be rotatable around its own swing axis. The upper end of the swing frame 122 can be connected to the swing shaft 121. The swing frame 122 can swing with the rotation of the swing shaft 121, that is, the swing frame 122 can swing around the swing axis. The first conveyor belt 123 and the second conveyor belt 124 can both be arranged on the swing frame 122. The second conveyor belt 124 can be arranged side by side with the first conveyor belt 123 in a direction perpendicular to the swing axis, thereby forming a conveying channel P2 that is linear, and the extension direction of the conveying channel P2 is perpendicular to the direction parallel to the swing axis. A conveying channel P2 for clamping the linked bag and conveying the linked bag downward can be formed between the first conveyor belt 123 and the second conveyor belt 124. The conveying channel P2 can fold the linked bag in half when it swings with the swing frame 122, thereby forming an S-shaped stacked linked bag arranged up and down. The material box 103 can be arranged below the outlet side of the conveying passage P2. The folded connected bags can be automatically put into the box.

[0085] The folding assembly 120 provided in this embodiment can provide a smooth, automatically tractionable and swingable conveying channel P2 through the folding assembly 120, so that the folding efficiency can be greatly improved by swinging and folding the connected bags during the conveying process. During the folding process, the connected bags can be kept in a compacted and flattened state to avoid the accumulation and jamming of the connected bags during the conveying process; and the conveying speed of the connected bags can be adjusted by adjusting the speed of the conveyor belt, and the swinging speed and angle of the swing frame 122 can be adjusted to meet the needs of various connected bags with different numbers and lengths of single bags, and meet the needs of folding different numbers of single bags at a time, thereby improving the working efficiency of the bag folding machine 100 and widely adapting to customized and flexible automatic production.

[0086] Further, one end of the drive shaft 111 can be connected to the output end of the drive motor 131. The other end of the drive shaft 111 can be connected to the support plate. The first material sorting belt 112 may include a first inlet end pulley 114, a first intermediate pulley 115 and a first outlet end pulley 116, and the height of the first intermediate pulley 115 is lower than the first inlet end pulley 114, but higher than the first outlet end pulley 116. Thus, a curved material sorting channel P1 in the middle can be formed to provide a clamping force in the middle of the material sorting channel P1. The second material sorting belt 113 may include a second inlet end pulley 117, a second intermediate pulley 118 and a second outlet end pulley 119, and the height of the second intermediate pulley 118 is higher than the second inlet end pulley 117, but higher than the second outlet end pulley 119.

[0087] The first intermediate pulley 115 , the first outlet end pulley 116 , the second inlet end pulley 117 , the second intermediate pulley 118 , and the second outlet end pulley 119 may all be supported by shafts.

[0088] The material sorting assembly 110 may include at least two first material sorting belts 112 and at least two second material sorting belts 113. At least two first material sorting belts 112 are arranged side by side and at intervals in a direction parallel to the drive axis. The first material sorting belt 112 corresponds to the second material sorting belt 113 one by one. Thus, at least two material sorting channels P1 can be formed. In the illustrated embodiment, two side-by-side first material sorting belts 112 and two side-by-side second material sorting belts 113 are shown, thereby forming two material sorting channels P1. The distance between the two first material sorting belts 112 can be set according to the width of the connected bag.

[0089] One end of the swing shaft 121 can be connected to the output end of the swing motor 132, and the other end of the swing shaft 121 can be connected to the bracket 101. The folding assembly 120 may include at least two first conveyor belts 123 and at least two second conveyor belts 124. At least two first conveyor belts 123 are arranged side by side and at intervals in a direction parallel to the swing axis. The first conveyor belt 123 corresponds to the second conveyor belt 124 one by one. Thus, at least two conveying channels P2 can be formed. In the illustrated embodiment, two side-by-side first conveyor belts 123 and two side-by-side second conveyor belts 124 are shown, thereby forming two conveying channels P2. The distance between the two first conveyor belts 123 can be set according to the width of the continuous bag.

[0090] Further, the bag folding machine 100 may also include a driven shaft 133 and a linkage belt 134. The driven shaft 133 can be rotatable around its own driven axis. The outlet end of the material sorting component 110 can be arranged on the driven shaft 133 and drive the driven shaft 133 to rotate. Specifically, the pulley at the outlet end of the first material sorting belt 112 or the second material sorting belt 113 can be arranged on the driven shaft 133. The driven shaft 133 can be driven by the pulley and rotate together with the pulley. The first end of the linkage belt 134 can be arranged on the driven shaft 133, and the second end of the linkage belt 134 can be used to drive the first conveyor belt 123 or the second conveyor belt 124. The driven shaft 133 can drive the linkage belt 134 to operate, and the linkage belt 134 can drive the first conveyor belt 123 or the second conveyor belt 124 to operate.

[0091] Of course, in other embodiments not shown, a small drive motor 131 may be provided on the swing frame 122 to operate the first conveyor belt 123 or the second conveyor belt 124 .

[0092] The linkage belt 134 may include a first linkage belt 135 and a second linkage belt 136. The two ends of the first linkage belt 135 are respectively arranged on the driven shaft 133 and the swing shaft 121. The two ends of the second linkage belt 136 are respectively arranged on the swing shaft 121 and the rotation shaft of the second conveyor belt 124, and the first linkage belt 135 and the second linkage belt 136 can share a linkage pulley 137. The rotation of the linkage pulley 137 and the swing of the swing shaft 121 are independent and do not interfere; that is, the swing shaft 121 can provide support force to the linkage pulley 137, but does not affect the rotation of the linkage pulley 137.

[0093] The second linkage belt 136 can be connected to the rotating shaft of the second conveyor belt 124 at the outlet end. In this embodiment, the second linkage belt 136 drives the rotating shaft of the second conveyor belt 124, so that the second conveyor belt 124 operates. When the second conveyor belt 124 operates, it drives the linked bag to move together, and the first conveyor belt 123 is passively driven by the second conveyor belt 124 through the linked bag to keep operating.

[0094] Further, the control device can be configured to make the swing frame 122 swing once, and at least one of the linked bags is conveyed through the conveying channel P2. Thus, at least one single bag in the linked bag can be folded into a layer. For example, in the folded linked bag, each layer can include one single bag or two single bags. The number of single bags in each layer can be adjusted as needed.

[0095] The bag folding machine 100 may further include a first position sensor 141 and a second position sensor 142. Both the first position sensor 141 and the second position sensor 142 can be connected to the control device. The first position sensor 141 may be disposed at the inlet end of the folding assembly 120. The first position sensor 141 is used to feedback an entry signal of the continuous bag entering the conveying channel P2. The control device may cause the swing frame 122 to start swinging according to the entry signal. The second position sensor 142 may be disposed at the outlet end of the folding assembly 120, and the second position sensor 142 is used to feedback a departure signal of the continuous bag leaving the conveying channel P2. The control device may cause the swing frame 122 to stop swinging according to the departure signal.

[0096] Return to see Figure 3 or Figure 4 The bag folding machine 100 may further include a first barcode scanner 143. Each single bag in the continuous bag may be provided with an identification code, such as a barcode or a QR code. The first barcode scanner 143 is used to scan the continuous bags on the continuous bag conveyor belt 102. The first barcode scanner 143 may be connected to the control device. The control device retrieves the number of continuous bags in the batch according to the first scanning information from the first barcode scanner 143 to determine the number of folding times.

[0097] The bag folding machine 100 may further include a second barcode scanner (not shown). The material box 103 may be provided with an identification code, such as a barcode or a QR code. The second barcode scanner can be provided on the bracket 101, and the second barcode scanner is used to scan the material box 103. The second barcode scanner may be connected to the control device. The control device is configured to match the first scanning information from the first barcode scanner 143 with the second scanning information from the second barcode scanner. When the two scanning information match, the folding mechanism may be activated. Conversely, when the two scanning information do not match, an error message is fed back, the folding mechanism is not started, and the correct material box 103 is replaced in time. The bag folding machine 100 may be provided with an alarm 144, and error information may be fed back through the alarm 144.

[0098] In this embodiment, by automatically matching the information of the connected bag and the material box 103, it is possible to adapt to customized bag folding and box packing, and effectively reduce the occurrence of customized incorrect box packing.

[0099] like Figure 6 As shown, the bag folding machine 100 may further include a lifting mechanism 150. The lifting mechanism 150 may be provided with a lifting platform 151 that can move up and down. The material box 103 may be placed on the lifting platform 151. The height of the material box 103 may be adjusted by means of the lifting platform 151 to adapt to changes in the folding shape and folding height of the continuous bag during the folding process. During the bag folding process, as the continuous bag is gradually loaded into the material box 103, the height of the continuous bag in the material box 103 gradually increases, and the lifting platform 151 may be gradually moved downward to lower the height of the material box 103 to adapt to the folding height of the continuous bag, thereby meeting efficient and continuous production.

[0100] The lifting mechanism 150 may include a lifting motor 152, a lifting belt 153, and a lifting guide rail 154. The lifting belt 153 is arranged vertically and can be connected to the output shaft of the lifting motor 152. The lifting motor 152 drives the output shaft to rotate, driving the lifting belt 153 to operate. The lifting guide rail 154 is arranged vertically, and the lifting platform 151 can be movably mounted to the lifting guide rail 154. The lifting platform 151 can move up and down on the lifting guide rail 154. The lifting platform 151 can be connected to the lifting belt 153, and the operation of the lifting belt 153 can drive the lifting platform 151 to move up and down. Two lifting guide rails 154 are arranged side by side, and the lifting platform 151 can be connected to the two lifting guide rails 154.

[0101] like Figure 7As shown, the bag folding machine 100 may also include a material box support platform 160. The material box 103 can be placed on the material box support platform 160. The material box support platform 160 can be set on the lifting platform 151. The material box support platform 160 can be provided with a material sorting rod 171. The material sorting rod 171 can be retractable in a direction perpendicular to the folding direction of the continuous bag. The figure shows a rectangular material box 103, and the folded continuous bag is placed in the length direction of the material box 103. The material sorting rod 171 can be retractable in the width direction of the material box 103. And the material sorting rod 171 can be reciprocated along a straight line perpendicular to the telescopic direction of the material sorting rod 171 to guide the folded continuous bag into the material box 103. The material sorting rod 171 can be a piston rod of a telescopic cylinder 174. The material sorting rod 171 can be reciprocated by a material sorting actuator 175 set on the material box support platform 160. For example, the telescopic cylinder 174 is disposed on the material handling actuator 175 and is driven by the material handling actuator 175 to swing back and forth.

[0102] In this embodiment, with the help of the material sorting rod 171, the folding effect of the connected bags can be blocked and adjusted, so that the stacked connected bags after being put into the box can be more neat and beautiful, and the phenomenon of staggered placement can be effectively reduced, especially for the parts with light weight, shallow folds, and hard indentations between connected bags, which can also be automatically folded into a beautiful and neat effect.

[0103] The material sorting rod 171 may include a first material sorting rod 172 and a second material sorting rod 173 arranged at intervals. The first material sorting rod 172 can swing from the middle of the material box 103 to one end of the material box 103. The second material sorting rod 173 can swing from the middle of the material box 103 to the other end of the material box 103 opposite to one end. And the first material sorting rod 172 and the second material sorting rod 173 are alternately extended and retracted. For example, when the first bag is folded and falls into the material box 103, the first material sorting rod 172 can extend and gradually swing from the middle of the material box 103 to one end of the material box 103. At this time, the tail end of the first bag corresponds to one end of the material box 103, the first material sorting rod 172 is retracted, and the first bag falls completely into the material box 103.

[0104] Similarly, when the second bag is folded and falls into the material box 103, the second material sorting rod 173 can extend and gradually swing from the middle of the material box 103 to the other end of the material box 103. At this time, the tail end of the second bag corresponds to the other end of the material box 103, and the second material sorting rod 173 is retracted, and the second bag completely falls into the material box 103. The first material sorting rod 172 and the second material sorting rod 173 are alternately extended and retracted until the entire bag strip is folded.

[0105] The material box support platform 160 may include a material box conveyor belt 161 and a material box positioning member 181. The material box conveyor belt 161 is used to receive the material box 103 from the material box 103 conveyor belt, and the material box positioning member 181 is disposed at the end of the material box conveyor belt 161 to block the movement of the material box 103.

[0106] The material box positioning member 181 can be retracted in a direction perpendicular to the material box conveyor belt 161. The material box positioning member 181 can be arranged at the retractable end of the positioning cylinder 182, and the positioning cylinder 182 can drive the material box positioning member 181 to be retracted to the top of the material box conveyor belt 161, or to be retracted from the top of the material box conveyor belt 161. The material box positioning member 181 can be movable in a direction parallel to the material box conveyor belt 161, thereby, the material boxes 103 of different lengths can be positioned, so that the material box support platform 160 can adapt to the material boxes 103 of different lengths. The material box positioning member 181 can be moved by the positioning actuator 183 arranged on the material box support platform 160. For example, the positioning cylinder 182 is arranged on the positioning actuator 183, and is driven by the positioning actuator 183 to move.

[0107] The magazine support platform 160 may be provided with a positioning sensor (not shown) for detecting the position of the magazine 103. When the positioning sensor detects that the magazine 103 is at a predetermined position, the magazine positioning member 181 is extended to the top of the magazine conveyor belt 161 to achieve the positioning of the magazine 103.

[0108] In this embodiment, the material box 103 can automatically be put in place, tighten the positioning, automatically rise and fall, and automatically package and discharge the materials.
