[0002] The packaging of materials such as silicon wafers is an important process in the production of silicon wafers. It is of great significance in the production process of silicon wafers. Traditional manual packaging requires manual placement of silicon wafers into packaging bags and the packaging of materials through manual operation, resulting in low packaging efficiency of silicon wafers. In addition, there is a probability of damaging the silicon wafers when manually taking the wafers out of the bags and packing them in boxes, which seriously affects production efficiency. Summary of the invention

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In the first aspect, the present application provides a bag folding device, including a load-bearing component, a transfer component, a feeding component and a folding component; the load-bearing component includes a load-bearing platform for placing packaging bags, the transfer component is located on one side of the load-bearing platform, the transfer component is used to grab the packaging bags and transport them to the load-bearing platform; the feeding component is located upstream of the load-bearing component, and is used to grab materials and transport them into the packaging bags; the folding component is located on one side of the load-bearing component, the folding component includes a first folding plate, a second folding plate and a rotating drive mechanism, the first folding plate and the second folding plate The first folding plate and the second folding plate are able to move toward each other in the height direction to clamp the bag opening of the packaging bag. There is a certain interval between the first folding plate and the second folding plate in the direction of the bag opening of the packaging bag, and the extension directions of the two are parallel to the horizontal plane and perpendicular to the direction of the bag opening of the packaging bag. When the two clamp the bag opening of the packaging bag, the first folding plate is clamped between the second folding plate and the packaging bag. The second folding plate is installed on the rotating drive mechanism, and the second folding plate can rotate around the first folding plate under the action of the rotating drive mechanism, so that the bag opening of the packaging bag is folded to the bottom of the packaging bag driven by the second folding plate.

[0006] Furthermore, the bag folding device also includes a smoothing assembly and a clamping assembly. The smoothing assembly is arranged downstream of the supporting assembly, and the clamping assembly is arranged between the smoothing assembly and the supporting assembly and can move between the smoothing assembly and the supporting assembly. The supporting platform has a accommodating portion with an opening direction toward the smoothing assembly. When the clamping assembly moves to a side close to the supporting platform, at least part of the clamping assembly is in the accommodating portion; when the material is transported to the packaging bag, the clamping assembly drives the packaging bag containing the material to move to the folding station between the smoothing assembly and the supporting assembly, and at the folding station, the bag mouth of the packaging bag is folded to the bottom of the packaging bag by the folding assembly.

[0007] Furthermore, the clamping assembly includes a first clamping unit and a second clamping unit arranged along the height direction, and the second clamping unit is arranged above the first clamping unit. The second clamping unit cooperates with the first clamping unit to clamp the packaging bag containing the material, and the second clamping unit can move synchronously with the first clamping unit; when the material is transported to the packaging bag, the first clamping unit can lift the packaging bag containing the material from bottom to top, so that the packaging bag containing the material leaves the surface of the supporting platform.

[0008] Furthermore, the supporting platform is basically U-shaped. When the first clamping unit is in the accommodating portion, the first clamping unit is basically located in the middle of the supporting platform, so that when the first clamping unit lifts the packaging bag containing the material, the first clamping unit is against the middle of the packaging bag containing the material.

[0009] Furthermore, the clamping assembly also includes a top block that can move in the height direction. When the bag opening of the packaging bag is folded to the bottom of the packaging bag, the top block can press the bag opening of the packaging bag from bottom to top. The second folding plate has a notch. When the top block presses the bag opening of the packaging bag, the top block is located in the notch, so that the second folding plate can be pulled away from the bottom of the packaging bag in a direction away from the notch.

[0013] Furthermore, the transfer assembly includes a first adsorption component and a moving mechanism. The first adsorption component is installed on the moving mechanism. The first adsorption component is used to grab the packaging bag and, under the action of the moving mechanism, transport the packaging bag to the supporting platform. The surface of the supporting platform has a second adsorption component. The upper and lower surfaces of the bag opening are respectively sucked by the first adsorption component and the second adsorption component, and the first adsorption component is driven by the moving mechanism to move to the side away from the supporting platform to open the bag opening of the packaging bag.

[0014] In a second aspect, the present application further provides a bagging and folding method, which is applied to any bagging and folding device in the first aspect, and the method comprises:

[0015] Grab the packaging bag by the first suction member and transport the packaging bag to the carrying platform;

[0016] The upper surface of the packaging bag is sucked by the first suction member, and the lower surface of the packaging bag is sucked by the second suction member arranged on the surface of the supporting platform. The first suction member moves away from the supporting platform under the action of the moving mechanism to open the bag mouth of the packaging bag;

[0017] The feeding component grabs the material and transports it into the packaging bag;

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0031] like Figure 1 As shown, the present application provides a bagging and folding device 100, which is a part of the tooling of a silicon wafer cartoning machine, and is used to move materials into packaging bags and package the materials. It can reduce material damage caused by manual bagging and improve the efficiency of silicon wafer bagging, wherein the materials can be silicon wafers.

[0032] The bagging and folding device 100 includes a carrying component 11, a transfer component 12 and a feeding component 13. The carrying component 11 includes a carrying platform 111. The carrying platform 111 is used to place packaging bags. The transfer component 12 is located at one side of the carrying platform 111. The transfer component 12 is used to grab the packaging bags and transport them to the carrying platform 111. The feeding component 13 is located upstream of the carrying component 11. The feeding component 13 is used to grab materials and transport them to the packaging bags on the carrying platform 111.

[0033] like Figure 2 As shown, specifically, a silo assembly 14 is provided next to the transfer assembly 12, and unused packaging bags are placed in the silo assembly 14. The transfer assembly 12 includes a first adsorbent 121 and a moving mechanism 122, the first adsorbent 121 is installed on the moving mechanism 122, the first adsorbent 121 is used to adsorb the packaging bag, and the first adsorbent 121 can also transport the packaging bag to the carrying platform 111 under the action of the moving mechanism 122.

[0034] Exemplarily, the first adsorbent 121 is configured as a suction cup, and the number of the first adsorbents 121 is set to four, and the four first adsorbents 121 are respectively adsorbed on the four corners of the packaging bag, thereby improving the stability of the transfer component 12 when grasping. The first adsorbent 121 is connected to an external vacuum machine through a pipeline, so that the first adsorbent 121 adsorbs the packaging bag by vacuum adsorption.

[0035] Furthermore, the moving mechanism 122 can drive the first adsorbent 121 to move in the height direction, so that the first adsorbent 121 can move into the silo assembly 14 to adsorb the packaging bag and remove the packaging bag from the silo assembly. The moving mechanism 122 can also drive the first adsorbent 121 to move in the horizontal direction, so that the first adsorbent 121 can move the packaging bag to the carrier 111.

[0036] Exemplarily, the moving mechanism 122 includes a transverse cylinder and a lifting module arranged on the transverse cylinder. The lifting module is connected to the first adsorption component 121 and drives the first adsorption component 121 to move in the height direction. The transverse cylinder drives the lifting module and the first adsorption component 121 to move in the horizontal direction, so that the packaging bag moves to the supporting platform 111 under the joint action of the lifting module and the transverse cylinder.

[0037] A second adsorption component 112 is provided on the surface of the supporting platform 111. When the packaging bag is placed on the supporting platform 111, the second adsorption component 112 adsorbs the lower surface of the packaging bag from below the packaging bag, and the moving mechanism 122 drives the first adsorption component 121 to move to the side away from the supporting platform 111 to open the bag mouth of the packaging bag.

[0038] Exemplarily, the second adsorbent 112 is a through hole opened on the carrier 111. When the packaging bag is located on the carrier 111, the second adsorbent 112 is located below the bag opening of the packaging bag. The second adsorbent 112 is connected to an external vacuum machine through a pipeline, so that the second adsorbent 112 can adsorb the packaging bag by vacuum adsorption. Optionally, the second adsorbent 112 can also be set as a suction cup, and the adsorption surface of the suction cup is parallel to the bearing surface of the carrier 111, so that the packaging bag can be laid flat on the carrier 111.

[0039] like Figure 3 As shown, the feeding assembly 13 includes a clamping cylinder 131, a first transverse module 132, and a pair of upper clamping jaws 133 and lower clamping jaws 134 arranged opposite to each other. The clamping cylinder 131 is configured to drive the upper clamping jaw 133 and the lower clamping jaw 134 to move relative to each other in the up-down direction, and the first transverse module 132 is configured to drive the upper clamping jaw 133 and the lower clamping jaw 134 to move synchronously in the horizontal direction. The upper clamping jaw 133 and the lower clamping jaw 134 are respectively located above and below the material. The upper clamping jaw 133 and the lower clamping jaw 134 can clamp the material under the action of the clamping cylinder 131, and move in the horizontal direction under the action of the first transverse module 132 to feed the material from the bag opening of the packaging bag into the packaging bag, thereby realizing the preliminary packaging of the material.

[0040] like Figure 4 As shown, as an implementation, the carrying assembly 11 further includes an expansion mechanism 113, and the expansion mechanism 113 is located on one side of the carrying platform 111 close to the feeding assembly 13 (see Figure 1 ), at least a portion of the expansion mechanism 113 can extend into the bag opening of the packaging bag and laterally expand the bag opening of the packaging bag.

[0041] Specifically, the expansion mechanism 113 includes a pair of expansion brackets 1131 and a second transverse module 1132 arranged opposite to each other, the second transverse module 1132 is connected to the two expansion brackets 1131, and the second transverse module 1132 is configured to drive the two expansion brackets 1131 to move relative to each other in the horizontal direction. When the bag opening of the packaging bag is opened, the second transverse module 1132 can drive the two expansion brackets 1131 to extend from the bag opening of the packaging bag into the packaging bag, and drive the two expansion brackets 1131 to move back in the horizontal direction, so that the bag opening of the packaging bag is laterally opened by the two expansion brackets 1131. The second transverse module 1132 includes but is not limited to a cylinder or a linear motor. Through the above arrangement, the bag opening can be fully expanded so that the feeding assembly 13 can put the material into the packaging bag, and avoid the situation where the material collides with the bag opening of the packaging bag when entering the packaging bag, causing the packaging bag to be pushed open and unable to package the material, thereby improving the packaging efficiency and safety during the material packaging process.

[0042] Exemplarily, taking any expansion bracket 1131 as an example, the expansion bracket 1131 includes two rod-shaped structural members arranged along the height direction, and the maximum distance between the two structural members is substantially consistent with the thickness of the packaging bag, so that the bag mouth of the packaging bag can be evenly opened.

[0043] Optionally, the expansion mechanism 113 includes a pair of expansion brackets 1131 arranged opposite to each other. Taking any one of the expansion brackets 1131 as an example, the expansion bracket 1131 is configured as a plate-shaped structural member.

[0044] like Figure 5 As shown, as an implementation, the bagging folding device 100 further includes a folding assembly 15, and the folding assembly 15 is located on one side of the carrying assembly 11 (see Figure 1 ), after the initial packaging (laying paper on the upper and lower surfaces of the material) is completed, the material is transported into the packaging bag, so that the folding component 15 can fold the packaging bag.

[0045] Specifically, the folding assembly 15 includes a first folding plate 151, a second folding plate 152 and a rotating drive mechanism 153, the second folding plate 152 is installed on the rotating drive mechanism 153, and the first folding plate 151 and the second folding plate 152 can move relative to each other in the height direction. It should be noted that the first folding plate 151 and the second folding plate 152 are arranged in the height direction, and the first folding plate 151 is located below the second folding plate 152, and the two can move toward each other to clamp the bag mouth of the packaging bag; after completing the folding of the packaging bag, the two can move back to each other, so that the first folding plate 151 and the second folding plate 152 can perform the next folding process.

[0046] The first folding plate 151 and the second folding plate 152 are spaced apart from each other in the direction of the bag opening of the packaging bag (see Figure 6), and their extension directions are parallel to the horizontal plane and perpendicular to the direction of the bag opening of the packaging bag. Based on this design, the first folding plate 151 can move upward to lift the bag opening of the packaging bag, so that a first crease is generated at the bag opening of the packaging bag. Since there is a certain interval 101 between the second folding plate 152 and the first folding plate 151, the second folding plate 152 can pass through the first folding plate 151 when moving downward, and press down the bag opening of the lifted packaging bag, so that a second crease is generated at the bag opening of the packaging bag. At this time, the first folding plate 151 and the second folding plate 152 clamp the bag opening of the packaging bag. When the two clamp the bag opening of the packaging bag, the first folding plate 151 is clamped between the second folding plate 152 and the packaging bag, or the first folding plate 151 is between the first crease and the second crease.

[0047] In the embodiment of the present application, the second folding plate 152 is installed on the rotating drive mechanism 153. When the first folding plate 151 and the second folding plate 152 clamp the bag mouth of the packaging bag, the second folding plate 152 can rotate around the first folding plate 151 under the action of the rotating drive mechanism 153, so that the bag mouth of the packaging bag is folded to the bottom of the packaging bag under the drive of the second folding plate 152, so as to realize the folding of the packaging bag. The rotating drive mechanism 153 includes but is not limited to a rotating cylinder or a motor.

[0048] In the prior art, materials are usually put into packaging bags manually, and the materials are packaged by manual operation, which results in low material packaging efficiency. In addition, there is a probability of damaging the materials during manual bagging, thereby affecting the material packaging efficiency. The present application provides an automatic packaging folding component 15, which improves the material packaging efficiency while avoiding material damage caused by manual bagging, thereby improving the material packaging efficiency.

[0049] like Figure 5 As shown, as an implementation, the hemming assembly 15 includes a first driving mechanism 154 and a second driving mechanism 155. The first hemming plate 151 is installed on the first driving mechanism 154, and the first driving mechanism 154 can drive the first hemming plate 151 to move in the up-down direction. The second hemming plate 152 is installed on the second driving mechanism 155, and the second driving mechanism 155 can drive the second hemming plate 152 to move in the up-down direction, thereby realizing the relative movement of the first hemming plate 151 and the second hemming plate 152.

[0050] In the embodiment of the present application, the first driving mechanism 154 and the second driving mechanism 155 are configured as lifting cylinders or linear motors.

[0051] like Figure 5As shown, specifically, the folding assembly 15 further includes a third driving mechanism 156, the first driving mechanism 154 and the second driving mechanism 155 are both installed on the third driving mechanism 156, and the third driving mechanism 156 is arranged on a corresponding guide rail extending in the horizontal direction, so that the third driving mechanism 156 can drive the first driving mechanism 154 and the second driving mechanism 155 to move synchronously in the horizontal direction, and the first folding plate 151 and the second folding plate 152 are controlled to approach the packaging bag or be withdrawn from the packaging bag under the action of the third driving mechanism 156. Among them, the third driving mechanism 156 includes but is not limited to a cylinder or a linear motor.

[0052] like Figure 5 As shown, as an implementation, the bagging folding device 100 further includes a hemming assembly 16 and a clamping assembly 17, the hemming assembly 16 is arranged downstream of the carrying assembly 11, and the clamping assembly 17 is arranged between the hemming assembly 16 and the carrying assembly 11 (see Figure 1 ), and can move between the hemming assembly 16 and the carrying assembly 11. Specifically, the carrying platform 111 has a receiving portion 114 (see Figure 2 ), when the clamping assembly 17 moves to a side close to the supporting platform 111, at least a portion of the clamping assembly 17 is in the accommodating portion 114.

[0053] It should be noted that in order to avoid interference between the second folding plate 152 and the supporting platform 111 when the second folding plate 152 rotates, when the material is transported into the packaging bag, the clamping assembly 17 clamps the packaging bag containing the material and drives the packaging bag containing the material to move to the folding station between the hemming assembly 16 and the supporting assembly 11, and at the folding station, the bag mouth of the packaging bag is folded to the bottom of the packaging bag through the folding assembly 15.

[0054] like Figure 7 As shown, as an implementation method, the clamping assembly 17 includes a first clamping unit 171 and a second clamping unit 172 arranged in the height direction, and the second clamping unit 172 is arranged above the first clamping unit 171, and the packaging bag containing the material is clamped by the cooperation of the second clamping unit 172 and the first clamping unit 171. The clamping assembly 17 also includes a transverse movement mechanism 173, and the first clamping unit 171 and the second clamping unit 172 are both installed on the transverse movement mechanism 173. The transverse movement mechanism 173 can drive the first clamping unit 171 and the second clamping unit 172 to move synchronously in the horizontal direction, so as to move the packaging bag containing the material to the folding station between the hemming assembly 16 and the bearing assembly 11.

[0055] It should be noted that after the folding of the current packaging bag is completed, the first folding plate 151 and the second folding plate 152 need to be separated from the packaging bag to facilitate folding the next packaging bag. In order to prevent the bag opening of the packaging bag from sliding due to separation and thus causing the folding of the packaging bag to fail, the clamping assembly 17 is also provided with a top block 174 that can move in the height direction. The top block 174 is arranged below the first clamping unit 171 and is located on the side of the first clamping unit 171 facing the support platform 111. When the second folding plate 152 presses the bag opening of the packaging bag under the packaging bag, the top block 174 can move from bottom to top to press the bag opening of the packaging bag so that the bag opening of the packaging bag will not slide when the second folding plate 152 is recovered. The second folding plate 152 has a notch 1521 (see Figure 5 ), the notch 1521 is connected to the outside, and when the top block 174 presses the bag opening of the packaging bag, the top block 174 is located in the notch 1521, so that the second folding plate 152 can be pulled away from the bottom of the packaging bag along the opening direction away from the notch 1521.

[0056] In some examples, the carrier 111 is substantially U-shaped, and when the first clamping unit 171 is in the accommodating portion 114, the first clamping unit 171 is substantially located in the middle of the carrier 111, so that when the first clamping unit 171 lifts up the packaging bag containing the material, the first clamping unit 171 abuts against the middle of the packaging bag containing the material. Based on this, when the second folding plate 152 folds the bag opening of the packaging bag to the bottom of the packaging bag, the second folding plate 152 will not interfere with the first clamping unit 171, and the top block 174 will not interfere with the first clamping unit 171.

[0057] like Figure 5 As shown, as an implementation, the bagging folding device 100 further includes a hemming assembly 16 and a conveying mechanism 18, and the hemming assembly 16 is arranged on both sides of the conveying mechanism 18. The hemming assembly 16 is located downstream of the carrying assembly 11 (see Figure 1 ), after the material is put into the packaging bag, it is transported to the edge smoothing component 16.

[0058] The edge smoothing assembly 16 includes edge smoothing plates 161 distributed on both sides of the conveying mechanism 18, and the edge smoothing plates 161 on both sides can move relatively. The edge smoothing plates 161 on either side include a first plate 1611 and a second plate 162 distributed up and down, and the first plate 1611 and the second plate 162 form an inclination angle greater than 0° and less than 180° toward the surface of the packaging bag.

[0059] When the transverse movement mechanism 115 transports the packaging bag to the smoothing assembly 16, the two smoothing pressing plates 161 are respectively located on the left and right sides of the packaging bag containing the material, and the first pressing plate 1611 is located above the packaging bag, and the second pressing plate 162 is located below the packaging bag. The smoothing pressing plates 161 on both sides can move in the direction close to the packaging bag containing the material. When the first pressing plate 1611 pushes the packaging bag to abut against the upper edge of the material, and the second pressing plate 162 pushes the packaging bag to abut against the lower edge of the material, the first pressing plate 1611 and the second pressing plate 162 can press the packaging bag and the material on both sides. In addition, after the two smoothing pressing plates 161 abut against the edge of the material, the smoothing pressing plates 161 on both sides can move in the direction away from the material, and the two sides of the packaging bag can be smoothed under the action of the first pressing plate 1611 and the second pressing plate 162. Through the above arrangement, it can be avoided that the packaging bag on both sides will be warped when the packaging bag is folded, thereby affecting the packaging of the material.

[0060] It should be noted that there is a gap between the first pressing plate 1611 and the second pressing plate 162 in the height direction, so as to prevent the first pressing plate 1611 and the second pressing plate 162 from clamping the packaging bag and causing damage to the packaging bag or dragging the packaging bag when the edge pressing plates 161 on both sides are away from the material.

[0061] Furthermore, the smoothing assembly 16 further includes a distance adjustment mechanism 162, and the smoothing plates 161 on both sides are mounted on the distance adjustment mechanism 162, and the distance mechanism is configured to be able to drive the two smoothing plates 161 to move in a direction close to the material, or to drive the two smoothing plates 161 to move in a direction away from the material, so as to adjust the distance between the two smoothing plates 161. The distance adjustment mechanism 162 includes but is not limited to a transverse cylinder or a linear motor.

[0062] As an implementation method, the smoothing assembly 16 includes an angle adjustment mechanism 163, and the first pressure plate 1611 and / or the second pressure plate 162 are installed on the angle adjustment mechanism 163. The angle adjustment mechanism 163 is configured to drive and adjust the relative rotation of the first pressure plate 1611 and / or the second pressure plate 162, thereby adjusting the inclination angle between the first pressure plate 1611 and the second pressure plate 162.

[0063] When the first pressing plate 1611 and the second pressing plate 162 are in contact with the packaging bag, the angle adjustment mechanism 163 can increase or decrease the inclination angle between the first pressing plate 1611 and the second pressing plate 162, thereby adjusting the pressure of the first pressing plate 1611 and the second pressing plate 162 on the packaging bag, thereby making the packaging bag and the material fit more closely. In addition, since the thickness of each material is different, by changing the inclination angle between the first pressing plate 1611 and the second pressing plate 162, the hemming assembly 16 can be applied to materials of different thicknesses, thereby improving the applicability of the bagging and folding device 100.

[0064] In the embodiment of the present application, the angle adjustment mechanism 163 is two motors, which are respectively connected to the first pressing plate 1611 and the second pressing plate 162 , so that the angle adjustment mechanism 163 can adjust the inclination angle between the first pressing plate 1611 and the second pressing plate 162 .

[0065] like Figure 5 As shown, as an implementation method, the conveying mechanism 18 includes two conveyor belts arranged opposite to each other, and there is a space between the two conveyor belts for the first clamping unit 171 to pass through. When the packaging bag containing the material completes the folding process, the clamping assembly 17 drives the packaging bag containing the material to move toward the conveying mechanism 18, and the first clamping unit 171 moves to the space between the two conveyor belts, so that the packaging bag containing the material is above the conveying mechanism 18. The first clamping unit 171 moves downward until the packaging bag containing the material is placed on the conveying mechanism 18, and the packaging bag containing the material is transported to the next node through the conveying mechanism 18.

[0066] Through the above arrangement, the automatic packaging, smoothing and folding processes of the materials are realized, the damage of the materials caused by manual bagging is reduced, and the efficiency of material bagging is improved.

[0067] The present application also provides a bagging and folding method, which is applied to the aforementioned bagging and folding device 100, and comprises the following steps:

[0068] S101 , grabbing a packaging bag by the first suction component 121 and transporting the packaging bag to the carrying platform 111 .

[0069] Illustratively, the first adsorption component 121 moves into the silo assembly 14 under the action of the moving mechanism 122 and grabs the packaging bag in the silo assembly 14. After the first adsorption component 121 grabs the packaging bag, the moving mechanism 122 drives the first adsorption component 121 to move toward the supporting platform 111 until the packaging bag is transported to the surface of the supporting platform 111.

[0070] S102, the upper surface of the packaging bag is sucked by the first adsorbent 121, and the lower surface of the packaging bag is sucked by the second adsorbent 112 arranged on the surface of the supporting platform 111. The first adsorbent 121 moves away from the supporting platform 111 under the action of the moving mechanism 122 to open the bag mouth of the packaging bag.

[0071] Exemplarily, when the packaging bag is transported to the surface of the carrier 111, the second adsorbent 112 adsorbs the lower surface of the packaging bag to fix the packaging bag on the carrier 111. At this time, the first adsorbent 121 moves away from the carrier 111 under the action of the moving mechanism 122. Since the lower surface of the packaging bag is adsorbed and fixed by the second adsorbent 112, when the upper surface of the packaging bag is lifted upward by the first adsorbent 121, the bag mouth of the packaging bag is opened.

[0072] Furthermore, when the bag opening of the packaging bag is opened, the expansion mechanism 113 located on the side of the support platform 111 close to the feeding assembly 13 extends into the packaging bag and opens a pair of expansion brackets 1131 in the horizontal direction, so that the bag opening of the packaging bag is opened.

[0073] S103, the feeding component grabs the material and transports the material into the packaging bag.

[0074] S104, controlling the first folding plate 151 and the second folding plate 152 to move close to the bag opening of the packaging bag, and move toward each other along the height direction to clamp the bag opening of the packaging bag.

[0075] Exemplarily, when the material is delivered into the packaging bag, the first clamping unit 171 and the second clamping unit 172 cooperate to clamp the upper and lower surfaces of the packaging bag containing the material, and the first clamping unit 171 moves upward and lifts the packaging bag containing the material, so that the packaging bag containing the material leaves the surface of the support platform 111. The first clamping unit 171 and the second clamping unit 172 move synchronously in the horizontal direction under the action of the transverse movement mechanism 173 to move the packaging bag containing the material to the folding station between the hemming assembly 16 and the support assembly 11. Further, the first folding plate 151 and the second folding plate 152 move toward the bag opening of the packaging bag under the action of the third driving mechanism 156, so that the first folding plate 151 moves below the bag opening of the packaging bag, and the second folding plate 152 moves above the bag opening of the packaging bag. The first folding plate 151 can move upward to lift the bag opening of the packaging bag, so that the first folding mark is generated at the bag opening of the packaging bag. The second folding plate 152 can pass through the first folding plate 151 when moving downward, and press down the bag opening of the lifted packaging bag, so that the bag opening of the packaging bag produces a second fold. At this time, the first folding plate 151 and the second folding plate 152 clamp the bag opening of the packaging bag.

[0076] S105. The second folding plate rotates around the first folding plate under the action of the rotary drive mechanism, so that the bag opening of the packaging bag is folded to the bottom of the packaging bag driven by the second folding plate.

[0077] Exemplarily, when the first folding plate 151 and the second folding plate 152 clamp the bag opening of the packaging bag, the second folding plate 152 can rotate around the first folding plate 151 under the action of the rotating drive mechanism 153, so that the bag opening of the packaging bag is folded to the bottom of the packaging bag driven by the second folding plate 152.

[0078] In the implementation manner of the present application, before executing step S104, the following steps are also included:

[0079] S201 , the first clamping unit 171 and the second clamping unit 172 move synchronously in the horizontal direction under the action of the transverse movement mechanism 173 to move the packaging bag containing the material to the edge smoothing component 16 .

[0080] S202, the two edge-smoothing pressing plates 161 move toward each other until they abut against the side edges of the packaging bag containing the material.

[0081] S203, after the two smoothing pressing plates 161 abut against the side edges of the packaging bag containing materials, the smoothing pressing plates 161 on both sides move away from the packaging bag containing materials, and the two side edges of the packaging bag containing materials can be smoothed under the action of the first pressing plate 1611 and the second pressing plate 162.

[0082] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be executed in an order different from that shown or described here.

[0083] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
