Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a pillow packaging line. Background Technology

[0002] Home textiles are essential items in people's lives, and pillows are indispensable in every household's bedding. Common types of pillows include: buckwheat pillows, kapok pillows, synthetic fiber pillows, latex pillows, and down pillows.

[0003] For fluffy pillow cores such as kapok pillows, synthetic fiber pillows, and down pillows, they need to be pre-compressed during packaging, then bagged and sealed, and the gas inside the packaging bag needs to be squeezed out when sealing.

[0004] Currently, many steps in pillow packaging require manual intervention. For example, people need to manually put the pillows into the open packaging bags and manually adjust the angle of the packaging bags on the conveyor line. This is time-consuming, labor-intensive, and results in low production capacity. Moreover, manual labor may soil the pillows, leading to a decline in product quality. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0062] Please see Figure 1 and Figure 2 One embodiment of this utility model provides a pillow 40 packaging line, including: a bagging conveying and compression mechanism 10, a pillow conveying mechanism 20, and a rolling and wrapping mechanism 30;

[0063] The bagging and compression mechanism 10 includes: a packaging bag conveying assembly 110, a cutting and sealing assembly 120 for cutting to form a packaging bag, a bagging assembly 130 for opening the bag opening, a compression and sealing assembly 140 for compressing the packaging bag and sealing the bag opening, and an angle adjustment assembly 150 for rotating the packaging bag by a preset angle. The cutting and sealing assembly 120, the bagging assembly 130, and the compression and sealing assembly 140 are arranged sequentially along the conveying direction of the packaging bag conveying assembly 110, and the cutting and sealing assembly 120 and the bagging assembly 130 are located on opposite sides of the packaging bag conveying assembly 110. The angle adjustment assembly 150 is located at the conveying end of the packaging bag conveying assembly 110.

[0064] The pillow conveying mechanism 20 is located on one side of the packaging bag conveying assembly 110, and on the same side as the bag-covering assembly 130, which is situated between the pillow conveying mechanism 20 and the packaging bag conveying assembly 110. The rolling mechanism 30, used for rolling the packaging bag, is located on the discharge side of the angle adjustment assembly 150. The discharge side of the angle adjustment assembly 150 refers to the side from which the packaging bag detaches from the angle adjustment assembly 150.

[0065] The cutting and sealing assembly 120 conveys the cut packaging bag to the packaging bag conveying assembly 110, which then conveys the packaging bag to the bag-covering assembly 130. The bag-covering assembly 130 opens the opening of the packaging bag, and the pillow conveying mechanism 20 conveys the pillow from the opening of the packaging bag into the packaging bag. Next, the packaging bag conveying assembly 110 conveys the packaging bag containing the pillow to the compression sealing assembly 140. The compression sealing assembly 140 compresses the packaging bag, causing the air inside the packaging bag to be expelled and the pillow to be compressed. The compression sealing assembly 140 then seals the opening of the packaging bag, thereby preventing air from entering the pillow. Gas enters the packaging bag, compressing the pillow and reducing its volume. At this point, the sealed end of the packaging bag faces the packaging bag conveying component 110. The packaging bag conveying component 110 then conveys the compressed and sealed packaging bag to the angle adjustment component 150. The angle adjustment component 150 rotates the packaging bag by a preset angle, aligning it with the orientation requirements of the rolling mechanism 30. The packaging bag then enters the rolling mechanism 30 with the correct orientation for rolling. Finally, the rolled packaging bag is placed inside a blast-proof bag, completing the pillow bagging, compression, rolling, and blast-proof bag placement process. It should be noted that the blast-proof bag is used to prevent the rolled packaging bag from bursting open and losing its rolled state.

[0066] The preset angle can be designed as needed. For example, in this embodiment, in order to better roll and reduce the volume, the packaging bag usually enters the rolling mechanism 30 parallel to the length direction of the packaging bag. The rolling mechanism 30 is located on the side of the angle adjustment component 150 away from the packaging bag conveying component 110. During the packaging bag cutting, pillowcase bag and packaging bag compression process, the length direction of the packaging bag is perpendicular to the conveying direction of the packaging bag conveying component 110. The two sealing positions of the packaging bag face the two sides of the packaging bag conveying component 110. Therefore, the preset angle is 90°. The angle adjustment component 150 rotates the packaging bag by 90° so that the sealing position of the packaging bag is in front of or behind the packaging bag in the conveying direction of the packaging bag conveying component 110. Then the packaging bag can enter the rolling mechanism 30 parallel to the length direction of the packaging bag.

[0067] Please see Figure 3 and Figure 4The specific structure of the angle adjustment component 150 can be selected according to actual needs. For example, the angle adjustment component 150 includes two sets of rotary drive rollers, each set of rotary drive rollers includes multiple rotary drive rollers, the two sets of rotary drive rollers are arranged side by side, and the two sets of rotary drive rollers can rotate in opposite directions. After the packaging bag reaches the two sets of rotary drive rollers, the rotation of the two sets of rotary drive rollers can drive the packaging bag to rotate. Alternatively, the angle adjustment component 150 includes a gripper module, which grips the packaging bag, and then the gripper module drives the packaging bag to rotate at a preset angle before putting the packaging bag down. In some optional embodiments, the angle adjustment component 150 includes a rotary support base 151 and a rotary drive module 152. The rotary support base 151 is set at the conveying end of the packaging bag conveying component 110, and the rotary drive module 152 is driven to connect with the rotary support base 151. The packaging bag conveying component 110 conveys the packaging bag to the rotary support base 151, and then the rotary drive module 152 drives the rotary support base 151 to rotate, thereby driving the packaging bag to rotate at a preset angle.

[0068] In some optional embodiments, the angle adjustment assembly 150 further includes a lifting drive module 153, a mounting bracket 154, and a plurality of auxiliary support rollers 155. The plurality of auxiliary support rollers 155 are arranged sequentially on the mounting bracket 154 along the conveying direction of the packaging bag conveying assembly 110, and the auxiliary support rollers 155 are rotatably mounted on the mounting bracket 154. A rotating support seat 151 is disposed between at least two auxiliary support rollers 155. The lifting drive module 153 is drivenly connected to the rotating support seat 151 and is capable of driving the rotating support seat 151 to rise to a position higher than the auxiliary support rollers 155. The rotating support base 151 first descends to a height no higher than the auxiliary support roller 155. The packaging bag conveying assembly 110 then conveys the packaging bag onto the auxiliary support roller 155. The packaging bag can be supported by the auxiliary support roller 155 or by both the auxiliary support roller 155 and the rotating support base 151 simultaneously. Subsequently, the lifting drive module 153 drives the rotating support base 151 to rise, so that the packaging bag is supported only by the rotating support base 151. Then, the rotating drive module 152 drives the rotating support base 151 to rotate by a preset angle so that the packaging bag rotates to a suitable angle. Next, the lifting drive module 153 drives the rotating support base 151 to descend to a height no higher than the auxiliary support roller 155, so that the packaging bag can be supported by the auxiliary support roller 155 or by both the auxiliary support roller 155 and the rotating support base 151 simultaneously. Then, the packaging bag can be conveyed to the next process. During the movement of the packaging bag, there is rolling friction between the auxiliary support roller 155 and the packaging bag. The rotation of the auxiliary support roller 155 facilitates the smooth movement of the packaging bag.

[0069] In order to ensure that the auxiliary support roller 155 can smoothly guide the packaging bag through the angle adjustment component 150, the conveying end of the packaging bag conveying component 110 and the wrapping mechanism 30 are respectively arranged on opposite sides of the angle adjustment component 150. The discharge side of the angle adjustment component 150 is the side of the angle adjustment component 150 away from the conveying end of the packaging bag conveying component 110.

[0070] The auxiliary support roller 155 can be driven to rotate by the power module, which facilitates the automatic delivery of the packaging bag to the rolling mechanism 30, or the packaging bag can be manually guided to move to the rolling mechanism 30.

[0071] The specific structure of the rotating support 151 can be selected according to actual needs. For example, in some optional embodiments, the multiple auxiliary support rollers 155 are divided into two groups, each group including multiple auxiliary support rollers 155. The multiple auxiliary support rollers 155 in the same group are arranged sequentially along the conveying direction of the packaging bag conveying assembly 110, and the two groups of auxiliary support rollers 155 are arranged side by side. The rotating support 151 includes a first rotating support member 1511 and a second rotating support member 1512. The first rotating support member 1511 and the second rotating support member 1512 are connected to each other. The rotating support 151 can be positioned relative to the auxiliary support rollers 155 at a first position. When the rotary support 151 is at the first angle, the first rotary support member 1511 can extend between the two sets of auxiliary support rollers 155, and the second rotary support member 1512 can extend between two adjacent auxiliary support rollers 155 in the same set of auxiliary support rollers 155, thus facilitating the concealment of the rotary support 151. When the rotary support 151 is at the second angle, the second rotary support member 1512 can extend between the two sets of auxiliary support rollers 155, and the first rotary support member 1511 can extend between two adjacent auxiliary support rollers 155 in the same set of auxiliary support rollers 155, thus facilitating the concealment of the rotary support 151. In this embodiment, the first angle can be 0° and 180°, and the second angle can be 90° and 270°.

[0072] In some optional embodiments, the rotating support 151 is provided with a plurality of first vacuum adsorption holes 1513. The first vacuum adsorption holes 1513 are connected to the negative pressure generating device. The first vacuum adsorption holes 1513 can adsorb the packaging bag onto the rotating support 151, thereby preventing the packaging bag from slipping between the packaging bag and the rotating support 151 when the rotating support 151 rotates, which would prevent the packaging bag from rotating to the predetermined angle correctly.

[0073] The specific structure of the lifting drive module 153 can be selected according to actual needs. For example, the lifting drive module 153 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. The specific structure of the rotary drive module 152 can be selected according to actual needs. For example, the rotary drive module 152 can use a rotary drive motor.

[0074] In this embodiment, the lifting drive module 153 may use multiple cylinders, which are connected to the transfer bracket. The rotation drive module 152 is installed on the transfer bracket, and the output shaft of the rotation drive module 152 is driven to connect to the rotation support 151. The lifting drive module 153 drives the rotation drive module 152 and the rotation support 151 to rise and fall by driving the transfer bracket to rise and fall.

[0075] Please see Figure 5 and Figure 6 In some optional embodiments, the cutting and sealing assembly 120 includes a first sealing module 121, a cutting module 122, and a feeding module 123. The first sealing module 121 and the cutting module 122 are disposed on one side of the packaging bag conveying assembly 110 and arranged sequentially in the direction close to the packaging bag conveying assembly 110. The feeding module 123 is disposed on one side of the cutting module 122. The feeding module 123 conveys the tubular bags onto the packaging bag conveying assembly 110. The tubular bags conveyed by the feeding module 123 pass through the cutting module 122 and the first sealing module 121. After the tubular bag reaches the appropriate length from the cutting module 122 to the packaging bag conveying assembly 110, the first sealing module 121 seals one end of the tubular bag, forming a welding mark. The cutting module 122 cuts the tubular bag to form a packaging bag of appropriate length. The welding mark is equivalent to sealing one end of the packaging bag, while the other end of the packaging bag is not sealed and faces the bagging assembly 130. This allows the packaging bag conveying assembly 110 to perform the bagging operation after conveying the packaging bag to the bagging assembly 130 without adjusting the angle of the packaging bag.

[0076] The feeding module 123 typically employs a winding module, which includes at least a winding roller on which the tubular bag is wound up. The winding roller can be connected to a motor to achieve active feeding. It should be noted that the packaging bag is cut from the tubular bag. Cutting the packaging bag from the tubular bag without sealing it will result in a packaging bag with openings at both ends. Therefore, one end of the packaging bag is sealed first, leaving the other end unsealed, thus creating an opening. This allows the pillow to be inserted into the opening of the packaging bag, which is then sealed again.

[0077] The first sealing module 121 can weld the upper and lower bag films of the tubular bag together, creating a weld line on the tubular bag. The cutting module 122 then cuts the tubular bag, and the cut portion becomes the packaging bag. In this embodiment, the first sealing module 121 includes a first sealing drive module 1211, a first sealing support seat 1212, and a first welding seat 1213. The first sealing drive module 1211 drives the first welding seat 1213 to move up and down on the first sealing support seat 1212. The tubular bag passes between the first welding seat 1213 and the first sealing support seat 1212. The first welding seat 1213 presses the tubular bag against the first sealing support seat 1212 and then welds it. This example is not limited to this one.

[0078] The specific structure of the cutting module 122 can be selected according to actual needs. For example, the cutting module 122 includes a cutting blade 1221 and a cutting drive module 1222. The cutting blade 1221 can be raised and lowered under the drive of the cutting drive module 1222. After the cutting blade 1221 descends, it cuts the tubular bag. In this embodiment, the first sealing drive module 1211 is also connected to the cutting drive module 1222, driving the first welding seat 1213 and the cutting drive module 1222 to rise and fall together. The cutting blade 1221 is arranged on the side of the first welding seat 1213 away from the packaging bag conveying assembly 110. To facilitate cutting, the first sealing drive module 1211 is also connected to a tubular bag pressing seat 1214. The tubular bag pressing seat 1214, the cutting blade 1221, and the first welding seat 1213 are arranged in sequence in the direction close to the packaging bag conveying assembly 110. The tubular bag pressing seat 1214 and the first welding seat 1213 together press the tubular bag onto the first sealing support seat 1212, thereby straightening the tubular bag. Then the cutting blade 1221 cuts, achieving stable and accurate cutting and avoiding cutting failure. An obstacle space 1215 can be provided on the first sealing support seat 1212 to avoid the cutting blade 1221 from passing through.

[0079] The specific structure of the first sealing drive module 1211 and the cutting drive module 1222 can be selected according to actual needs. For example, the first sealing drive module 1211 and the cutting drive module 1222 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module or a linear motor translation drive module, etc., so as to drive the first welding seat 1213 and the cutting tool 1221 to rise and fall accordingly.

[0080] In some optional embodiments, the cutting and sealing assembly 120 further includes a first upper bag film adsorption module 124, a first lower bag film adsorption module 125, a first bag film lifting drive module 126, a bag lifting component 127, and a bag lifting translation drive module 128. The first lower bag film adsorption module 125 is disposed on one side of the packaging bag conveying assembly 110, and the first upper bag film adsorption module 124 is vertically and vertically disposed above the first lower bag film adsorption module 125. The first lower bag film adsorption module 125 and the first upper bag film adsorption module 126 are connected to the first lower bag film conveying assembly 110. Each bag film adsorption module 124 is provided with several second vacuum adsorption holes, which are used to connect to a negative pressure generating device. The first bag film lifting drive module 126 is driven to connect with the first upper bag film adsorption module 124. The bag lifting component 127 is located above the packaging bag conveying assembly 110. The bag lifting translation drive module 128 is driven to connect with the bag lifting component 127. The bag lifting component 127 moves towards or away from the first sealing module 121 under the drive of the bag lifting translation drive module 128. The first lower bag film adsorption module 125 can be located on the side of the first sealing module 121 facing the packaging bag conveying assembly 110, or it can be located on the side of the first sealing module 121 away from the packaging bag conveying assembly 110. In this embodiment, the first lower bag film adsorption module 125 is located on the side of the first sealing module 121 away from the packaging bag conveying assembly 110. The direction in which the bag lifting component 127 is moved by the bag lifting translation drive module 128 is perpendicular to the conveying direction of the packaging bag conveying assembly 110.

[0081] After the tubular bag is conveyed to the end and reaches between the first lower bag film adsorption module 125 and the first bag film lifting drive module 126, the negative pressure generating device is activated, so that a negative pressure is formed at the second vacuum adsorption hole of the first lower bag film adsorption module 125 and adsorbs the lower bag film of the tubular bag. Meanwhile, the first upper bag film adsorption module 124 descends under the drive of the first bag film lifting drive module 126, so that the first upper bag film adsorption module 124 abuts against the upper bag film of the tubular bag. Then, the first bag film lifting drive module 126 drives the first upper bag film adsorption module 124 to rise, so that the upper bag film of the tubular bag is lifted, thereby initially opening the opening of the tubular bag. Then, the bag lifting component 127 extends into the tubular bag from the opening under the drive of the bag lifting translation drive module 128 and is supported by the bag lifting component 127. As the feeding module 123 conveys the tubular bag, the end of the tubular bag will move toward the packaging bag conveying assembly 110 away from the first sealing module 121. The bag lifting piece 127 also moves with the end of the tubular bag under the drive of the bag lifting translation drive module 128. When the first sealing module 121 and the cutting module 122 complete the sealing and cutting operations, the bag lifting piece 127 can detach from the tubular bag, which helps the packaging bag to be smoothly laid out on the packaging bag conveying assembly 110, avoiding wrinkles in the packaging bag, or preventing the end of the channel from bending and shifting due to friction when the end of the tubular bag moves on the packaging bag conveying assembly 110, thus preventing the posture of the packaged bag formed after cutting from not meeting the requirements on the packaging bag conveying assembly 110.

[0082] The specific structure of the first bag film lifting drive module 126 and the bag translation drive module 128 can be selected according to actual needs. For example, the first bag film lifting drive module 126 and the bag translation drive module 128 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0083] Please see Figure 7 and Figure 8The specific structure of the bagging assembly 130 can be selected according to actual needs. For example, in some optional embodiments, the bagging assembly 130 includes a second upper bag film adsorption module 131, a second lower bag film adsorption module 132, a second bag film lifting drive module 133, a first bag support component 134, a second bag support component 135, a bag support lifting drive module 136, and a bag support translation drive module 137. The second lower bag film adsorption module 132 is disposed on one side of the packaging bag conveying assembly 110, and the second upper bag film adsorption module 131 is movably disposed above the second lower bag film adsorption module 132. Both the second lower bag film adsorption module 132 and the second upper bag film adsorption module 131 are provided with a plurality of third... Vacuum adsorption hole 1311, the third vacuum adsorption hole 1311 is used to connect to the negative pressure generating device, the second bag film lifting drive module 133 is driven to connect with the second upper bag film adsorption module 131; the first bag support member 134 and the second bag support member 135 can both be lifted and lowered on one side of the packaging bag conveying assembly 110, the second bag support member 135 is located above the first bag support member 134, the bag lifting drive module 136 is driven to connect with the second bag support member 135, the bag translation drive module 137 is driven to connect with the first bag support member 134 and the second bag support member 135, the first bag support member 134 and the second bag support member 135 move closer to or away from the packaging bag conveying assembly 110 under the drive of the bag translation drive module 137.

[0084] The tubular bag is cut by the cutting and sealing assembly 120 to obtain a packaging bag with one end sealed. At this time, the sealed end of the packaging bag faces the cutting and sealing assembly 120, while the unsealed end of the packaging bag faces the bag-covering assembly 130. The packaging bag conveying module conveys the packaging bag. After the unsealed end of the packaging bag reaches between the second upper bag film adsorption module 131 and the second lower bag film adsorption module 132, the conveying stops. Then, the negative pressure generating device is activated, so that a negative pressure is formed at the third vacuum adsorption hole 1311 of the second lower bag film adsorption module 132 and adsorbs the lower bag film of the packaging bag. The second upper bag film adsorption module 131 is lowered under the drive of the second bag film lifting drive module 133, so that the second upper bag film adsorption module 131 abuts against the upper bag film of the packaging bag. Then, the second bag film lifting drive module 133 drives the second upper bag film adsorption module 131 to rise, so that the upper bag film of the packaging bag is lifted, thereby initially opening the bag opening.

[0085] Subsequently, the bag-supporting translation drive module 137 drives the first bag-supporting component 134 and the second bag-supporting component 135 to move towards the opening of the packaging bag, so that the first bag-supporting component 134 and the second bag-supporting component 135 extend into the opening of the packaging bag. At this time, the adsorption of the packaging bag by the second upper bag film adsorption module 131 and the second lower bag film adsorption module 132 can be released, and the second upper bag film adsorption module 131 is raised to avoid the subsequent movement of the second bag-supporting component 135; then the bag-supporting lifting drive module 136 drives the second bag-supporting component 135 to move towards the opening of the packaging bag. As the first support member 134 maintains the bottom of the bag opening, the second support member 135 rises and moves the top of the bag opening upward, thus opening the bag opening to a sufficient size. Then, the pillow can be stuffed into the bag. After the pillow is stuffed, the second support member 135 descends, and the second support member 135 and the first support member 134 exit from the bag opening. Subsequently, the bag conveying assembly 110 moves the bag containing the pillow to the compression sealing assembly 140.

[0086] The specific structure of the second bag film lifting drive module 133 and the bag supporting translation drive module 137 can be selected according to actual needs. For example, the second bag film lifting drive module 133 and the bag supporting translation drive module 137 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0087] Please see Figure 9 In some optional embodiments, the compression sealing assembly 140 includes a pressing seat 141, a pressing drive module 142, and a second sealing module 143. The pressing seat 141 is vertically and flexibly disposed above the packaging bag conveying assembly 110. The pressing drive module 142 is drivenly connected to the pressing seat 141. The second sealing module 143 is disposed on one side of the packaging bag conveying assembly 110 and is located on the same side of the packaging bag conveying assembly 110 as the bag-covering assembly 130. The position of the second sealing module 143 corresponds to one side of the pressing seat 141, so that when the packaging bag containing the pillow moves under the pressing seat 141, the opening of the packaging bag is also located at the second sealing module 143. The pressing drive module 142 drives the pressing seat 141 to press down, thereby compressing the packaging bag and the pillow, thereby expelling the air inside the packaging bag and reducing the thickness of the pillow. Then, the second sealing module 143 seals the opening of the packaging bag, thereby achieving the sealing of the pillow by the packaging bag.

[0088] The second sealing module 143 can weld the upper and lower bag films of the packaging bag together, forming a weld line and sealing the bag opening. In this embodiment, the second sealing module 143 includes a second sealing drive module 1431, a second sealing support seat 1432, and a second welding seat 1433. The second sealing drive module 1431 drives the second welding seat 1433 to move up and down on the second sealing support seat 1432. The packaging bag is conveyed by the packaging bag conveying assembly 110 and arrives between the second welding seat 1433 and the second sealing support seat 1432. The second welding seat 1433 presses the packaging bag against the second sealing support seat 1432 and then welds it. This example is not limited to this one. In addition, the second sealing drive module 1431 can be installed on one side of the pressure seat 141, so that the second welding seat 1433, the pressure seat 141, and the second welding seat 1433 can move up and down together under the drive of the pressure drive module 142. The structure of the second sealing module 143 can be referenced from the structure of the first sealing module 121. Its principle is also known to those skilled in the art and will not be described in detail here.

[0089] The specific structure of the pressure drive module 142 can be selected according to actual needs. For example, the pressure drive module 142 can be a lead screw drive module, a rotary motor drive module, a belt drive module, a cylinder drive module, or a linear motor drive module. In this embodiment, the pressure drive module 142 includes multiple pressure drive cylinders. The output shaft of the pressure drive cylinder is connected to the pressure seat 141, driving the pressure seat 141 to rise and fall relative to the packaging bag conveying assembly 110.

[0090] Please see Figures 10 to 12 The specific structure of the pillow conveying mechanism 20 can be selected according to actual needs. For example, in some optional embodiments, the pillow conveying mechanism 20 includes a feeding assembly 210 and a pre-compression assembly 220.

[0091] The feeding assembly 210 includes a first feeding conveying module 211, a second feeding conveying module 212, and a feeding lifting drive module 213. The second feeding conveying module 212 is disposed above the first feeding conveying module 211. The feeding lifting drive module 213 is drivenly connected to the second feeding conveying module 212 and is used to drive the second feeding conveying module 212 to lift relative to the first feeding conveying module 211. A feeding conveying space 214 is formed between the first feeding conveying module 211 and the second feeding conveying module 212. The feeding conveying space 214 extends along the conveying direction of the first feeding conveying module 211.

[0092] The pre-compression assembly 220 includes a first pre-compression conveying module 221, a second pre-compression conveying module 222, and a pre-compression lifting drive module 223. The second pre-compression conveying module 222 is disposed above the first pre-compression conveying module 221. The pre-compression lifting drive module 223 is drivenly connected to the second pre-compression conveying module 222 and is used to drive the second pre-compression conveying module 222 to lift relative to the first pre-compression conveying module 221, thereby facilitating the compression of the pillow 40 to a suitable thickness. A pre-compression space 224 is formed between the first pre-compression conveying module 221 and the second pre-compression conveying module 222. The pre-compression space 224 extends along the conveying direction of the first pre-compression conveying module 221, and the beginning of the pre-compression space 224 is correspondingly arranged at the end of the feeding conveying space 214. The bagging assembly 130 is located between the end of the pre-compression space 224 and the packaging bag conveying assembly 110.

[0093] The pillow 40 can be pre-compressed by the pillow conveying mechanism 20, allowing it to enter the packaging bag with a smaller thickness. During pre-compression, the pillow 40 first enters the first feeding conveying module 211 and is located within the feeding conveying space 214. Subsequently, the feeding lifting drive module 213 drives the second feeding conveying module 212 to descend, causing the second feeding conveying module 212 to press against the top of the pillow 40. The first feeding conveying module 211 applies force to the bottom of the pillow 40, while the second feeding conveying module 212 applies force to the top of the pillow 40, ensuring that the pillow 40 can smoothly and stably enter the pre-compression space 224, avoiding insufficient force applied to the pillow 40 and... Unevenness causes the pillow 40 to tilt and prevent it from entering the pre-compression space 224. Moreover, the second feeding conveyor module 212 can also be lowered to a suitable position to pre-compress the pillow 40 to a certain extent, reducing the thickness of the pillow 40 and making it easier for the pillow 40 to enter the pre-compression space 224. When a part of the pillow 40 enters the pre-compression space 224, the first pre-compression conveyor module 221 and the second pre-compression conveyor module 222 apply force to the pillow 40, causing the pillow 40 to gradually enter the pre-compression space 224. The pillow 40 enters the pre-compression space 224 and then detaches from the end of the pre-compression space 224 and enters the packaging bag at the bagging assembly 130.

[0094] It should be noted that the overall height of the feeding and conveying space 214 needs to be greater than the overall height of the pre-compression space 224.

[0095] Furthermore, when compressing multiple pillows 40, they need to be stacked sequentially from top to bottom in the feeding conveyor space 214. The second feeding conveyor module 212 can also be lowered to a suitable position so that the multiple pillows 40 are compressed to a thickness that allows them to smoothly enter the pre-compression space 224. Therefore, it can accommodate pre-compression of single or multiple pillows 40. Moreover, when pre-compressing multiple pillows 40, because the second feeding conveyor module 212 can be lowered and pressed, the multiple pillows 40 are less likely to tip over or become misaligned, so the multiple pillows 40 can smoothly enter the pre-compression space 224 simultaneously.

[0096] The second pre-compression conveying module 222 can be raised and lowered relative to the first pre-compression conveying module 221, thereby adjusting the height of the pre-compression space 224 and adjusting the thickness of the pre-compressed pillow 40. In particular, when multiple pillows 40 need to be pre-compressed, the height of the second pre-compression conveying module 222 usually needs to be adjusted to meet the thickness requirements of the multiple pre-compressed pillows 40.

[0097] It should be noted that the beginning of the feeding conveying space 214 refers to the rear end of the feeding conveying space 214 in the conveying direction of the first feeding conveying module 211, and the end of the feeding conveying space 214 refers to the front end of the feeding conveying space 214 in the conveying direction of the first feeding conveying module 211. The beginning of the pre-compression space 224 refers to the rear end of the pre-compression space 224 in the conveying direction of the first pre-compression conveying module 221, and the end of the pre-compression space 224 refers to the front end of the pre-compression space 224 in the conveying direction of the first pre-compression conveying module 221.

[0098] The specific structure of the loading and lifting drive module 213 can be selected according to actual needs. For example, the loading and lifting drive module 213 can adopt a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. In this embodiment, the loading and lifting drive module 213 adopts a linear motor translation drive module.

[0099] The specific structure of the pre-compression lifting drive module 223 can be selected according to actual needs. For example, the pre-compression lifting drive module 223 can adopt a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. In this embodiment, the pre-compression lifting drive module 223 adopts a cylinder translation drive module.

[0100] The specific structure of the first feeding conveyor module 211 and the second feeding conveyor module 212 can be selected according to actual needs. For example, the first feeding conveyor module 211 and the second feeding conveyor module 212 can adopt a mesh belt conveyor, a roller conveyor, a chain conveyor, or a belt conveyor.

[0101] In some optional embodiments, the second pre-compression conveying module 222 is provided with a pre-compression roller 2221 and a pre-compression drive assembly 2222. The pre-compression roller 2221 is rotatably positioned above the beginning of the pre-compression space 224. The pre-compression drive assembly 2222 is drivenly connected to the pre-compression roller 2221 to drive the pre-compression roller 2221 to rotate. The pre-compression roller 2221 can abut against and drive the pillow 40 to achieve compression. When the pre-compression roller 2221 rotates, the friction between the pre-compression roller 2221 and the pillow 40 can smoothly drive the pillow 40 into the pre-compression space 224. Moreover, the pre-compression roller 2221 itself is a horizontally arranged cylindrical roller, which can smoothly guide and compress the pillow 40.

[0102] Please see Figure 11 and Figure 13 The specific structures of the first pre-compression conveying module 221 and the second pre-compression conveying module 222 can be selected according to actual needs. For example, the first pre-compression conveying module 221 and the second pre-compression conveying module 222 can adopt a mesh belt conveyor, a roller conveyor, a chain conveyor, or a belt conveyor. In some optional embodiments, both the first pre-compression conveying module 221 and the second pre-compression conveying module 222 include a pre-compression plate 2223 and a pre-compression conveying belt 2224. The pre-compression conveying belt 2224 is arranged around the pre-compression plate 2223 and can circulate around the pre-compression plate 2223 to drive the pillow 40 to move. The pre-compression space 224 is formed between the pre-compression conveying belt 2224 of the first pre-compression conveying module 221 and the pre-compression conveying belt 2224 of the second pre-compression conveying module 222. The pre-compression plate 2223 can apply a stable supporting force to the pre-compression conveyor belt 2224, so that the pillow 40 in the pre-compression space 224 can be stably clamped by the pre-compression conveyor belt 2224 of the first pre-compression conveyor module 221 and the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222, thus preventing the pillow 40 from expanding.

[0103] Because a gap will exist between the pre-compression roller 2221 and the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222 when the pre-compression roller 2221 is positioned outside the pre-compression conveyor belt 2224, the pillow 40 may expand after passing the pre-compression roller 2221 and fail to enter the pre-compression space 224 smoothly. This gap may even cause the pillow 40 to become stuck between the pre-compression roller 2221 and the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222, affecting production. Therefore, in some optional embodiments, the second pre-compression conveyor module 222 includes a pre-compression roller 2221 and a pre-compression drive assembly 2222. The pre-compression roller 2221 is rotatably positioned above the beginning of the pre-compression space 224, and the pre-compression drive assembly 2222 is driven by the pre-compression roller 2221 to drive its rotation. The pre-compression conveyor belt 2224 of the compression conveyor module 222 is arranged around the pre-compression plate 2223 and the pre-compression roller 2221 of the second pre-compression conveyor module 222. The pre-compression roller 2221 contacts the pillow 40 through the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222. Therefore, when the pre-compression roller 2221 rotates, the pre-compression roller 2221 drives the pillow 40 smoothly into the pre-compression space 224 through the friction between the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222. Therefore, after the pillow 40 is separated from the feeding conveyor space 214, it directly contacts the pre-compression conveyor belt 2224 of the first pre-compression conveyor module 221 and the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222 and enters the pre-compression space 224 without any gaps that would cause the pillow 40 to expand and get stuck.

[0104] Furthermore, since the pre-compression roller 2221 abuts against the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222, the rotation of the pre-compression roller 2221 can drive the pre-compression conveyor belt 2224 of the second pre-compression conveyor module 222 to move, thereby eliminating the need for a separate power module to drive the pre-compression conveyor belt 2224 and simplifying the structure. Of course, when the pre-compression roller 2221 and the pre-compression drive assembly 2222 are not provided, the second pre-compression conveyor module 222 may also include a conveyor belt drive module, which is drivenly connected to the pre-compression conveyor belt 2224 to drive the pre-compression conveyor belt 2224 to move around the pre-compression plate 2223, and this example is not limited to this one. In this embodiment, the first pre-compression conveying module 221 may adopt the same structure as the second pre-compression conveying module 222; however, in some other optional embodiments, the first pre-compression conveying module 221 may not be provided with the pre-compression roller 2221 and the pre-compression drive assembly 2222, while only the second pre-compression conveying module 222 includes the pre-compression roller 2221 and the pre-compression drive assembly 2222. In this case, the first pre-compression conveying module 221 may also include a conveyor belt drive module, which is drivenly connected to the pre-compression conveyor belt 2224 and is used to drive the pre-compression conveyor belt 2224 to move around the pre-compression plate 2223.

[0105] In some optional embodiments, the second pre-compression conveying module 222 further includes a conveyor belt tensioning roller 2225. The conveyor belt tensioning roller 2225 is disposed on top of the pre-compression conveyor belt 2224 of the second pre-compression conveying module 222 and is located on the side of the pre-compression roller 2221 away from the feeding conveying space 214. The conveyor belt tensioning roller 2225 presses the pre-compression conveyor belt 2224 against the pre-compression roller 2221 and / or the pre-compression plate 2223 of the second pre-compression conveying module 222. The conveyor belt tensioning roller 2225 is used to tension the pre-compression conveyor belt 2224 of the second pre-compression conveying module 222, which helps to prevent the pre-compression roller 2221 and the pre-compression conveyor belt 2224 from slipping when the pre-compression drive assembly 2222 drives the pre-compression conveyor belt 2224 to move through the pre-compression roller 2221.

[0106] In some alternative implementations, the diameter of the pre-compression roller 2221 is greater than the thickness of the pre-compression plate 2223 of the second pre-compression conveying module 222. The curved surface of the side of the pre-compression roller 2221 can be used to guide the compression of the pillow 40. The pre-compression roller 2221 needs to have a sufficiently large diameter to better guide the compression of thicker pillows 40 or multiple stacked pillows 40.

[0107] In this embodiment, the pre-compression lifting drive module 223 is connected to the pre-compression plate 2223 of the second pre-compression conveying module 222, and the pre-compression roller 2221 of the second pre-compression conveying module 222 is rotatably mounted on the pre-compression plate 2223 of the second pre-compression conveying module 222.

[0108] Please see Figure 12 and Figure 14 In some optional embodiments, the feeding assembly 210 further includes a stacking module 215, which includes a stacking clamping drive module 2151 and two stacking clamping members 2152. The two stacking clamping members 2152 are respectively disposed on both sides of the second feeding and conveying module 212. The stacking clamping drive module 2151 is drivenly connected to the two stacking clamping members 2152 to drive the two stacking clamping members 2152 to clamp and engage. When pre-compressing multiple pillows 40, the current pillow 40 can be clamped by the stacking module 215 and placed on the pillow 40 that subsequently enters the first feeding conveyor module 211, thereby achieving automated stacking. The process of stacking two pillows 40 is described below: After the first pillow 40 enters the first feeding conveyor module 211, the feeding lifting drive module 213 drives the second feeding conveyor module 212 to descend, causing the stacking module 215 to descend as well. After the two stacking clamps 2152 are on both sides of the pillow 40, the two stacking clamps 2152 move closer to each other under the drive of the stacking clamping drive module 2151, thereby clamping the first pillow 40. Then, the loading lifting drive module 213 drives the second loading conveyor module 212 to rise, thereby causing the first pillow 40 to rise. Next, the second pillow 40 enters the first loading conveyor module 211. The loading lifting drive module 213 drives the second loading conveyor module 212 to fall, causing the first pillow 40 to reach the top of the second pillow 40. The two stacking clamps 2152 move away from each other under the drive of the stacking clamp drive module 2151, thereby releasing the first pillow 40 and placing the first pillow 40 on top of the second pillow 40, thereby realizing automated stacking operation. Then, the step of pre-compressing the two stacked pillows 40 can be carried out. When there are more than two pillows 40 to be stacked, the above steps can also be referred to. The height of the stacking clamp 2152 should be designed to be no greater than the height of a single pillow 40 so that when there is only a single pillow 40, the second feeding and conveying module 212 can descend and press against the pillow 40. Alternatively, the stacking clamp 2152 can be detachably connected to the second feeding and conveying module 212 through a screw structure, a snap-fit ​​structure or other locking structure, so that the stacking clamp 2152 can be disassembled or replaced with a suitable stacking clamp 2152 according to the number of pillows 40.

[0109] In addition, when multiple pillows 40 need to be stacked, the stacking clamp 2152 can also help guide the movement of the pillows 40 and prevent the pillows 40 from tipping over.

[0110] In addition, the structure of the stacking clamp 2152 can be designed appropriately according to the structure of the pillow 40. For example, in this embodiment, the stacking clamp 2152 includes an arc plate and a support fold. The arc plates of the two stacking clamps 2152 gradually bend towards each other from top to bottom. The support fold is provided on one side of the bottom end of the arc plate. The support fold is used to support the pillow 40 when clamping it. The arc plate is more suitable for the shape of the pillow 40, and also allows the support fold to be closer to the bottom of the pillow 40.

[0111] In some optional embodiments, the feeding assembly 210 further includes a centering module 216. The centering module 216 includes a centering drive module 2161 and two centering components 2162. The two centering components 2162 are respectively disposed on both sides of the feeding conveying space 214. The centering drive module 2161 is drivenly connected to the two centering components 2162 and is used to drive the two centering components 2162 to move closer to or away from each other. The centering module 216 is mainly used to correct the position of the pillow 40. After each pillow 40 arrives at the first feeding conveying module 211, the position of the pillow 40 can be corrected first, and then the second feeding conveying module 212 descends to press the pillow 40 and conveys it to the pre-compression space 224, so that the pillow 40 can be accurately aligned. Alternatively, after the pillow 40 is corrected, the stacking module 215 stacks the pillows 40 so that multiple pillows 40 can be stacked neatly. After the pillow 40 arrives at the first feeding and conveying module 211, the centering drive module 2161 can drive the two centering components 2162 to move closer to each other, thereby pushing the pillow 40 to the middle position or other suitable position of the first feeding and conveying module 211. Then, the two centering components 2162 move away from each other to achieve the correction operation. The specific structure of the centering drive module 2161 can be designed according to actual needs. For example, the centering drive module 2161 can be a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. In one embodiment, the centering drive module 2161 may include a centering drive motor and two gear and rack transmission mechanisms. The centering drive motor is connected to the two centering components 2162 through the two gear and rack transmission mechanisms, thereby driving the two centering components 2162 to move synchronously. Alternatively, the centering drive module 2161 may include two electric cylinders, which are connected to the two centering components 2162.

[0112] In some optional embodiments, the pre-compression assembly 220 further includes a bagging translation drive module 225, which, together with the first pre-compression conveying module 221 and the second pre-compression conveying module 222, drives the first pre-compression conveying module 221 and the second pre-compression conveying module 222 to move synchronously toward or away from the bagging assembly 130. When the pre-compressed pillow 40 needs to be bagged, the bagging translation drive module 225 can move the first pre-compression conveying module 221 and the second pre-compression conveying module 222 together toward the bagging assembly 130, so that parts of the first pre-compression conveying module 221 and the second pre-compression conveying module 222 extend into the packaging bag. Then, the first pre-compression conveying module 221 and the second pre-compression conveying module 222 transport the pre-compressed pillow 40, so that the pillow 40 leaves the pre-compression space 224 and enters the packaging bag. This ensures that the pillow 40 enters the packaging bag smoothly and avoids the pillow 40 expanding again after leaving the pre-compression space 224 and before reaching the packaging bag, which would prevent the pillow 40 from entering the packaging bag. After the pillow 40 enters the packaging bag, the first pre-compression conveying module 221 and the second pre-compression conveying module 222 are driven by the bagging translation drive module 225 to detach from the packaging bag, so that the packaging bag can enter the next compression and sealing step.

[0113] The specific structure of the bagging translation drive module 225 can be designed according to actual needs. For example, the bagging translation drive module 225 can be a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. It is not limited to this example. In this embodiment, the bagging translation drive module 225 adopts a synchronous belt translation drive module. The first pre-compression conveying module 221 and the pre-compression lifting drive module 223 can be set on the translation frame 226. The second pre-compression conveying module 222 can be lifted and lowered relative to the translation frame 226. The synchronous belt translation drive module is driven to connect with the translation frame 226. By driving the translation frame 226 to move, the first pre-compression conveying module 221 and the second pre-compression conveying module 222 move synchronously.

[0114] Please see Figure 15 The specific structure of the roll-up mechanism 30 can be selected according to actual needs. For example, the roll-up mechanism 30 includes: a switching component 310, a roll-up limiting component 320, a roll-up component 330, and a pushing component 340.

[0115] The winding limiting component 320 has a first winding limiting cavity 321 and a second winding limiting cavity 322. The switching component 310 is driven to the winding limiting component 320. The winding limiting component 320 can switch to the first posture and the second posture under the drive of the switching component 310. The winding component 330 is used to wind the packaging bag in the first winding limiting cavity 321 or the second winding limiting cavity 322. The pushing component 340 is used to push out the workpiece in the first winding limiting cavity 321 or the second winding limiting cavity 322.

[0116] When the rolling limiting component 320 is in the first posture, the first rolling limiting cavity 321 is located at the rolling component 330 and is on the discharge side of the angle adjustment component 150. The packaging bag that is detached from the discharge side of the angle adjustment component 150 will enter the first rolling limiting cavity 321. During the process of the packaging bag entering the first rolling limiting cavity 321, the rolling component 330 gradually rolls the packaging bag into a cylindrical shape, so that the packaging bag is restricted in the first rolling limiting cavity 321 in a cylindrical shape. The second rolling limiting cavity 322 is located at the pushing component 340.

[0117] When the rolling limiting component 320 is in the second posture, the second rolling limiting cavity 322 is located at the rolling component 330 and is on the discharge side of the angle adjustment component 150. The packaging bag that detaches from the discharge side of the angle adjustment component 150 will enter the second rolling limiting cavity 322. During the process of the packaging bag entering the second rolling limiting cavity 322, the rolling component 330 gradually rolls the packaging bag into a cylindrical shape, so that the packaging bag is restricted in the second rolling limiting cavity 322 in a cylindrical shape. The first rolling limiting cavity 321 is located at the pushing component 340.

[0118] The first rolling limiting cavity 321 and the second rolling limiting cavity 322 can prevent the packaged bag rolled into a cylindrical shape from unfolding or bursting.

[0119] Taking the initial position of the rolling limiting component 320 as an example, the workflow of the rolling mechanism is explained as follows: The first packaging bag enters the first rolling limiting cavity 321. The rolling component 330 rolls the first packaging bag into the first rolling limiting cavity 321, causing the first packaging bag to be rolled into a cylindrical shape. Subsequently, the switching component 310 switches the rolling limiting component 320 to the second position, so that the first rolling limiting cavity 321 is located at the push component 340. At this time, the explosion-proof bag can be placed on the end of the first rolling limiting cavity 321 away from the push component 340 by manual operation or special equipment. The push component 340 extends into the first rolling limiting cavity 321 and pushes the first packaging bag located in the first rolling limiting cavity 321 into the explosion-proof bag, completing the process. The process of packing the first packaging bag into the explosion-proof bag involves the second packaging bag entering the second rolling limiting cavity 322 and being rolled into a cylindrical shape by the rolling component 330, since the second rolling limiting cavity 322 is located at the rolling component 330. Subsequently, the switching component 310 switches the rolling limiting component 320 to the first position, so that the first rolling limiting cavity 321 returns to the rolling component 330 and the third packaging bag is rolled. The second packaging bag in the second rolling limiting cavity 322 can then be pushed into the explosion-proof bag by the pushing component 340. This cycle is repeated to achieve a fast rolling and bagging process. Since the rolling operation and the explosion-proof bag filling operation can be performed simultaneously, it is beneficial to improve work efficiency.

[0120] Please see Figure 16 and Figure 17 The specific structure of the rolling limiting component 320 can be selected according to actual needs. For example, in some optional embodiments, the rolling limiting component 320 includes two limiting modules 323, each including two limiting pressure plates 3231. A first rolling limiting cavity 321 is formed between the two limiting pressure plates 3231 of one limiting module 323, and a second rolling limiting cavity 322 is formed between the two limiting pressure plates 3231 of the other limiting module 323. The switching component 310 is driven to connect with the limiting pressure plates 3231, and the explosion-proof bag can be placed on the outside of the two limiting pressure plates 3231, so that part of the first rolling limiting cavity 321 or the second rolling limiting cavity 322 is inside the explosion-proof bag. The pushing component 340 can stably push the packaging bag into the explosion-proof bag.

[0121] In some optional embodiments, the limiting module 323 further includes a pressure plate mounting base 3232 and a pressure plate adjustment module 3233. The limiting pressure plate 3231 and the pressure plate adjustment module 3233 are mounted on the pressure plate mounting base 3232. The pressure plate adjustment module 3233 is driven to connect with at least one limiting pressure plate 3231. Under the drive of the pressure plate adjustment module 3233, the two limiting pressure plates 3231 move closer to each other or further away from each other. The switching component 310 is driven to connect with the pressure plate mounting base 3232. The pressure plate adjustment module 3233 can be simultaneously driven to connect with two limiting pressure plates 3231 of the same limiting module 323. By driving the two limiting pressure plates 3231 to move simultaneously, they can move closer to or further away from each other. The pressure plate adjustment module 3233 can also be driven to connect with one of the limiting pressure plates 3231 of the same limiting module 323. By moving one of the limiting pressure plates 3231 closer to the other limiting pressure plate 3231 of the same limiting module 323, the two limiting pressure plates 3231 can move closer to or further away from each other. By adjusting the distance between the two limiting pressure plates 3231, the size of the first rolling limiting cavity 321 or the second rolling limiting cavity 322 can be adjusted to accommodate packaging bags of different diameters formed by rolling.

[0122] The specific structure of the pressure plate adjustment module 3233 can be selected according to actual needs. For example, the pressure plate adjustment module 3233 can adopt a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. In this embodiment, the pressure plate adjustment module 3233 includes an adjustment motor, an adjustment gear, and two adjustment racks. The adjustment motor is mounted on the pressure plate mounting base 3232 and is driven and connected to the adjustment gear. The two adjustment racks are correspondingly mounted on the two limit pressure plates 3231. The adjustment racks mesh with the adjustment gear. The adjustment motor drives the adjustment gear to rotate, which in turn drives the adjustment racks to move, thereby driving the two limit pressure plates 3231 to move synchronously.

[0123] The switching component 310 drives the coiling limit component 320 to switch between the first and second postures. The appropriate design can be selected according to actual needs. The switching component 310 can drive the coiling limit component 320 to translate or rotate, thereby realizing the posture switching of the coiling limit component 320. For example, the switching component 310 may include two multi-axis translation drive modules. The multi-axis translation drive modules are driven to the pressure plate mounting base 3232 of the limit module 323, which can drive the limit module 323 to translate in multiple directions, thereby realizing the posture switching of the coiling limit component 320 by moving the limit module 323. Alternatively, the switching component 310 is a rotary motor. The rotary motor is driven to the coiling limit component 320, driving the coiling limit component 320 to rotate, thereby realizing the posture switching of the coiling limit component 320. In some optional embodiments, the coiling limiting assembly 320 further includes a rotating frame 324, a switching assembly 310 is driven to the rotating frame 324, and a limiting pressure plate 3231 is disposed on the rotating frame 324. The switching assembly 310 drives the rotating frame 324 to rotate so that the coiling limiting assembly 320 can switch to a first posture and a second posture. The coiling assembly 330 and the pushing assembly 340 can be correspondingly arranged on both sides of the rotation axis of the rotating frame 324. The switching assembly 310 can be a motor and a support shaft. The support shaft is driven to the rotating frame 324, and the motor is driven to the support shaft. The motor drives the rotating frame 324 to rotate by driving the support shaft to rotate. In this embodiment, the pressure plate mounting seat 3232 is mounted on the rotating frame 324. The pressure plate mounting seat 3232 can be integrally formed with the rotating frame 324, or the pressure plate mounting seat 3232 can be mounted on the rotating frame 324 by means of threaded connection, welding, etc., and is not limited to this example.

[0124] In some optional embodiments, at least one limiting plate 3231 in the same limiting module 323 is provided with a bag pressing module 3234. The bag pressing module 3234 is located outside the first rolling limiting cavity 321 or the second rolling limiting cavity 322. The bag pressing module 3234 on the limiting module 323 corresponding to the first rolling limiting cavity 321 is used to press the explosion-proof bag onto the limiting plate 3231 of the limiting module 323 corresponding to the first rolling limiting cavity 321. The bag pressing module 3234 on the limiting module 323 corresponding to the second rolling limiting cavity 322 is used to press the explosion-proof bag onto the limiting plate 3231 of the limiting module 323 corresponding to the second rolling limiting cavity 322.

[0125] The bag-body clamping module 3234 includes a bag-body clamping component 3235 and a clamping drive module 3236. The bag-body clamping component 3235 is movably mounted on the limiting pressure plate 3231. The clamping drive module 3236 is drivenly connected to the bag-body clamping component 3235. The bag-body clamping component 3235 moves closer to or further away from the limiting pressure plate 3231 as the clamping drive module 3236 moves. When the explosion-proof bag is outside the two limiting pressure plates 3231, the clamping drive module 3236 can drive the bag-body clamping component 3235 to move towards the limiting pressure plate 3231, thereby pressing the explosion-proof bag onto the limiting pressure plate 3231. This prevents the explosion-proof bag from shifting its position when the pushing component 340 pushes the packaging bag into the explosion-proof bag, thus avoiding bagging failure. In this embodiment, each limiting pressure plate 3231 is provided with a bag-body clamping module 3234.

[0126] The specific structure of the clamping drive module 3236 can be selected according to actual needs. For example, the clamping drive module 3236 can be a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0127] Please see Figure 18 and Figure 19 In some optional embodiments, the coiling assembly 330 includes a coiling clamping module 331, a coiling drive module 332, and an avoidance drive module 333. The coiling drive module 332 is driven to the coiling clamping module 331 and is used to drive the coiling clamping module 331 to rotate. The avoidance drive module 333 is driven to the coiling clamping module 331.

[0128] When the winding limiting component 320 is in the first posture, the first winding limiting cavity 321 is located at one end of the winding clamping module 331. The avoidance driving module 333 drives the winding clamping module 331 to move so that at least a portion of the winding clamping module 331 extends into the first winding limiting cavity 321 or the winding clamping module 331 disengages from the first winding limiting cavity 321. When the winding limiting component 320 is in the second posture, the second winding limiting cavity 322 is located on one side of the winding clamping module 331. The avoidance driving module 333 drives the winding clamping module 331 to move so that at least a portion of the winding clamping module 331 extends into the second winding limiting cavity 322 or the winding clamping module 331 disengages from the second winding limiting cavity 322.

[0129] When rolling is required, the rolling clamping module 331, driven by the avoidance drive module 333, extends into the first rolling limiting cavity 321 or the second rolling limiting cavity 322, clamping the end of the packaging bag. Then, driven by the rolling drive module 332, it rotates, causing the packaging bag to roll around the rolling clamping module 331 into a cylindrical shape. When the rolling limiting assembly 320 needs to change its posture, the rolling clamping module 331, driven by the avoidance drive module 333, disengages from the first rolling limiting cavity 321 or the second rolling limiting cavity 322, thereby preventing the rolling clamping module 331 from obstructing the translation or rotation of the rolling limiting assembly 320.

[0130] After the coiling clamping module 331 extends into one end of the first coiling limiting cavity 321 or the second coiling limiting cavity 322, the end of the coiling clamping module 331 away from the coiling drive module 332 is usually suspended. When the length of the first coiling limiting cavity 321 and the second coiling limiting cavity 322 is relatively long, the length of the coiling clamping module 331 also needs to be increased accordingly. This causes the coiling clamping module 331 to be unstable and easy to shake because the suspended end is unsupported. Therefore, in some optional embodiments, the coiling assembly 330 includes two coiling clamping modules 331 and two coiling drive modules 332. The two coiling drive modules 332 are driven connected to the two coiling clamping modules 331 respectively, avoiding the drive module 333 from being driven connected to the two coiling clamping modules 331.

[0131] When the winding limiting component 320 is in the first posture and the winding clamping module 331 is in the first winding limiting cavity 321, the two winding clamping modules 331 are arranged sequentially along the direction from one end to the other end of the first winding limiting cavity 321.

[0132] When the winding limiting assembly 320 is in the second posture and the winding clamping module 331 is in the second winding limiting cavity 322, the two winding clamping modules 331 are arranged sequentially along the direction from one end to the other end of the second winding limiting cavity 322.

[0133] By increasing the number of winding modules, the length of a single winding clamping module 331 is reduced, preventing the winding clamping module 331 from becoming too long and easily wobbling. The winding clamping modules 331 of the two winding modules can extend into the first winding limiting cavity 321 from both ends or into the second winding limiting cavity 322 from both ends, respectively, driven by the corresponding avoidance drive components. Alternatively, the winding clamping modules 331 of the two winding modules can extend into the first winding limiting cavity 321 from one side or into the second winding limiting cavity 322 from one side, etc., driven by the corresponding avoidance drive components. This is not a limitation.

[0134] The specific structure of the rolling clamping module 331 can be selected according to actual needs. For example, the rolling clamping module 331 includes two rolling rods 3311, a rolling clamping drive module 3312, and a rolling base. The two rolling rods 3311 are mounted on the rolling base and clamped together under the drive of the rolling clamping drive module 3312. After the two rolling rods 3311 clamp the packaging bag, the rolling drive module 332 drives the two rolling rods 3311 to rotate, thereby causing the packaging bag to be wound around the two rolling rods 3311, so as to realize the rolling of the packaging bag. The coiling is performed within the first coiling limiting cavity 321 or the second coiling limiting cavity 322. The coiling clamping drive module 3312 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. For example, the coiling clamping drive module 3312 includes a synchronous belt drive module, which is driven to one of the coiling rods 3311, driving one of the coiling rods 3311 to translate so as to achieve clamping and cooperation with the other coiling rod 3311. This example is not limited to this one.

[0135] The specific structure of the winding drive module 332 can be selected according to actual needs. For example, the winding drive module 332 can adopt a winding drive motor 3321 and a winding assembly base 3322. The winding drive motor 3321 is connected to the winding assembly base 3322 to drive the winding assembly base 3322 to rotate. Two winding rods 3311 are set on the winding assembly base 3322. The winding clamping drive module 3312 is connected to the winding assembly base 3322. This example is not limited to this one. In this embodiment, the coiling assembly 3322 is provided with a shaft hole, and the coiling clamping drive module 3312 includes a clamping drive motor 3313, a coiling transmission shaft, a coiling drive gear 3314, and two coiling drive racks 3315. The coiling transmission shaft passes through the shaft hole, the coiling drive gear 3314 is disposed on the coiling transmission shaft, and the coiling drive racks 3315 are respectively connected to the coiling rod 3311 and mesh with the coiling drive gear 3314. The clamping drive motor 3313 is driven by the coiling transmission shaft. Since the coiling assembly 3322 can rotate relative to the coiling transmission shaft through the shaft hole, the clamping drive motor 3313 can drive the coiling rod 3311 to move through the coiling transmission shaft without being installed on the coiling assembly 3322, and will not hinder the rotation of the coiling assembly 3322.

[0136] The combination of the coiling clamping module 331 and the coiling drive module 332 is a common technology in the field, and its structure is not limited to the above.

[0137] The specific structure of the avoidance drive module 333 can be selected according to actual needs. For example, the avoidance drive module 333 can adopt a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. The avoidance drive module 333 can drive the two coiling clamping modules 331 to move separately. For example, the avoidance drive module 333 includes two belt translation drive modules, and the two belt translation drive modules drive the coiling clamping modules 331 to move accordingly. Alternatively, the avoidance drive module 333 can drive the two coiling clamping modules 331 to move synchronously. For example, the avoidance drive module 333 includes a belt translation drive module, and the two coiling clamping modules 331 are both connected to the belt of the belt translation drive module. Since the belt moves in a cycle, the two coiling clamping modules 331 can be connected at the position where the belt moves relative to each other, so that the coiling clamping modules 331 can move synchronously in opposite directions or towards each other. In addition, in this embodiment, the coiling clamping module 331 is connected to the coiling drive module 332, and the coiling drive module 332 can be mounted on the transition movable frame 334. The transition movable frame 334 and the avoidance drive module 333 are connected so that the avoidance drive module 333 drives the coiling clamping module 331 and the coiling drive module 332 to move simultaneously through the transition movable frame 334. The transition movable frame 334 can be slidably mounted on the frame of the pillow 40 packaging line. Of course, in other embodiments, the avoidance drive module 333 can also directly drive the coiling clamping module 331 to move, and the coiling drive module 332 drives the coiling clamping module 331 and the avoidance drive module 333 to rotate together. This is not a limitation.

[0138] In some optional embodiments, the push component 340 includes a pusher 341 and a push driver module 342, wherein the push driver module 342 is drivenly connected to the pusher 341.

[0139] When the rolling limiting component 320 is in the first posture, the pusher 341 is located at one end of the second rolling limiting cavity 322. The pusher 341 can extend into or out of the second rolling limiting cavity 322 under the drive of the push drive module 342. By extending into the second rolling limiting cavity 322, the already rolled packaging bag in the second rolling limiting cavity 322 is pushed out of the second rolling limiting cavity 322. After pushing, the pusher 341 exits the second rolling limiting cavity 322, thereby avoiding affecting the switching posture of the rolling limiting component 320.

[0140] When the rolling limiting component 320 is in the second posture, the pusher 341 is located at one end of the first rolling limiting cavity 321. The pusher 341 can extend into or out of the first rolling limiting cavity 321 under the drive of the push drive module 342. By extending into the first rolling limiting cavity 321, the already rolled packaging bag in the first rolling limiting cavity 321 is pushed out of the first rolling limiting cavity 321. After pushing, the pusher 341 exits the first rolling limiting cavity 321, thereby avoiding affecting the switching posture of the rolling limiting component 320.

[0141] The specific structure of the push drive module 342 can be selected according to actual needs. For example, the push drive module 342 can be a lead screw translation drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example. In this embodiment, the push drive module 342 adopts a push cylinder, and the output shaft of the push cylinder is drivenly connected to the push member 341.

[0142] In some optional embodiments, the pushing component 340 also includes a feeding tray 343. When the rolling limiting component 320 is in the first posture, the pushing component 341 and the feeding tray 343 are respectively located at both ends of the second rolling limiting cavity 322. When the pushing component 341 pushes the already rolled packaging bag in the second rolling limiting cavity 322 out of the second rolling limiting cavity 322, the packaging bag will enter the explosion-proof bag that is wrapped outside the second rolling limiting cavity 322. After the packaging bag is completely separated from the second rolling limiting cavity 322, the explosion-proof bag containing the packaging bag can fall on the feeding tray 343. The feeding tray 343 can play a supporting role, which is convenient for the staff to operate and convenient for subsequent feeding and transfer operations.

[0143] When the rolling limiting component 320 is in the second posture, the pusher 341 and the unloading bracket 343 are respectively located at both ends of the first rolling limiting cavity 321. When the pusher 341 pushes the already rolled packaging bag out of the first rolling limiting cavity 321, the packaging bag will enter the explosion-proof bag that is wrapped outside the first rolling limiting cavity 321. After the packaging bag is completely separated from the first rolling limiting cavity 321, the explosion-proof bag containing the packaging bag can fall onto the unloading bracket 343. The unloading bracket 343 can play a supporting role, which is convenient for the staff to operate and for subsequent unloading and transfer operations.

[0144] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
