[0046] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0049] See also Figure 1 and Figure 2 An embodiment of the present invention provides a packaging device 10 of an embodiment, including a stacking and collecting device 100, a bagging device 200 and a bag sealing device 300.

[0050] It is understandable that the packaging equipment 10 may further include a frame 400 , and the stacking and collecting device 100 , the bagging device 200 and the bag sealing device 300 may all be disposed on the frame 400 .

[0051] The stacking and collecting device 100 is used to automatically stack and collect the materials to be packaged so as to facilitate the bagging device 200 to take them out. It can be understood that in some embodiments, the stacking and collecting device 100 can be omitted.

[0052] The bagging device 200 is used to open the bag opening of the packaging bag and put the materials collected by the stacking and collecting device 100 into the packaging bag with the bag opening opened.

[0053] The bag sealing device 300 is used to seal the packaging bag with the product already filled and the bag opening opened.

[0054] See also Figure 3 An embodiment of the present invention provides a stacking and collecting device 100 of an embodiment, including a loading component 110, a collecting component 120 and a sorting component 130.

[0055] The loading assembly 110 is used for loading materials.

[0056] See also Figure 5The material receiving assembly 120 includes a material receiving panel 121, a flip inclined plate 122 and a material receiving telescopic plate 123. The material receiving panel 121 is arranged on one side of the material loading assembly 110, and the material receiving panel 121 is provided with a material receiving opening. The flip inclined plate 122 is arranged below the material receiving panel 121 and corresponds to the material receiving opening (not marked in the figure). The material receiving telescopic plate 123 and the flip inclined plate 122 together constitute a material receiving space, and the material receiving telescopic plate 123 can move relative to the flip inclined plate 122, and the flip inclined plate 122 can rotate toward the side where the material receiving telescopic plate 123 is located.

[0057] See also Figure 4 The sorting component 130 has a sorting pressure plate 131, and the sorting pressure plate 131 can move relative to the feeding component 110 to press the material on the feeding component 110 and drive the pressed material to move to the receiving port of the receiving panel 121.

[0058] When the stacking and collecting device 100 is working, the material is loaded from the loading assembly 110 and moves to a position close to the collecting assembly 120. The sorting pressure plate 131 of the sorting assembly 130 moves relative to the loading assembly 110 to hold the material on the loading assembly 110 and drive the held material to move to the collecting port of the collecting panel 121. The material falls from the collecting port to the flip inclined plate 122 below, and then the flip inclined plate 122 rotates toward the side where the collecting telescopic plate 123 is located, thereby driving the material on the flip inclined plate 122 to be flipped and collected on the collecting telescopic plate 123; as the material on the collecting telescopic plate 123 increases, the collecting telescopic plate 123 moves away from the flip inclined plate 122 to ensure the collecting space, and when the material on the collecting telescopic plate 123 is taken out, the collecting telescopic plate 123 moves closer to the flip inclined plate 122 to return to its original position. In this way, the stacking and collecting device 100 can realize the automatic stacking and collecting of sheet products such as masks and towels, avoiding the problem of low efficiency of manual operation and greatly improving work efficiency.

[0059] It can be understood that the bottom of the material receiving telescopic plate 123 is set to a rough surface, and the bottom of the material receiving telescopic plate 123 has a certain friction to ensure that the sheet material can lean well on the flip inclined plate 122 without sliding on the material receiving telescopic plate 123 and becoming a flat state.

[0060] Furthermore, the initial position of the material receiving telescopic plate 123 is relatively close to the flip inclined plate 122. Figure 6 As shown, as the material on the material receiving telescopic plate 123 is collected, the material receiving telescopic plate 123 moves a preset distance relative to the flip inclined plate 122 in a direction away from the flip inclined plate 122, which is equivalent to the material receiving telescopic plate 123 extending relative to the flip inclined plate 122; this is repeated until the preset material receiving amount is reached, such as Figure 5When the preset material receiving quantity is reached, the material on the receiving telescopic plate 123 is taken out, and the receiving telescopic plate 123 moves closer to the flip inclined plate 122 to return to its original position, which is equivalent to the contraction of the receiving telescopic plate 123 relative to the flip inclined plate 122.

[0061] See also Figure 4 In some embodiments, the sorting assembly 130 further includes a first driving component 132 and a second driving component 133. The first driving component 132 is connected to the sorting platen 131 and is used to drive the sorting platen 131 to move up and down relative to the loading assembly 110 to hold the material on the loading assembly 110. The second driving component 133 is connected to the first driving component 132 and is used to drive the sorting platen 131 to move relative to the loading assembly 110 toward the side where the receiving panel 121 is located, so as to drive the held material to move to the receiving port of the receiving panel 121.

[0062] Furthermore, the first driving component 132 can be a driving component capable of realizing linear motion, such as a cylinder; the second driving component 133 can be a driving component capable of realizing linear motion, such as a linear motor. Furthermore, the second driving component 133 can be fixed to other components so that the sorting plate 131 is located above the loading assembly 110.

[0063] Furthermore, the sorting assembly 130 further includes a sorting baffle 134, which is connected to the bottom of the sorting pressure plate 131 and is located on the side of the sorting pressure plate 131 away from the material receiving panel 121. In this way, when the sorting pressure plate 131 drives the pressed material to move to the material receiving port of the material receiving panel 121, the sorting baffle 134 can play a role of limiting, preventing the material from escaping from under the sorting pressure plate 131 and facilitating the material to be moved to the material receiving panel 121, and then to the material receiving port.

[0064] See also Figure 5 , Figure 7 In some embodiments, the material receiving assembly 120 also includes a third driving component 124 and a fourth driving component 125. The third driving component 124 is connected to the material receiving telescopic plate 123 and is used to drive the material receiving telescopic plate 123 to move relative to the flip inclined plate 122. The fourth driving component 125 is connected to the flip inclined plate 122 and is used to rotate the flip inclined plate 122 toward the side where the material receiving telescopic plate 123 is located.

[0065] Further, the third driving component 124 is a turning power source, which can be realized by at least two mutually hinged cylinders. Specifically, the third driving component 124 is connected to the back side of the turning inclined plate 122, where the back side refers to a surface opposite to the surface of the turning inclined plate 122 for receiving the material dropped from the receiving port. Further, the fourth driving component 125 can be a driving component capable of realizing linear motion, such as a cylinder, a linear motor, etc. Specifically, the fourth driving component 125 is connected to the bottom of the receiving telescopic plate 123.

[0066] In some embodiments, the material receiving telescopic plate 123 includes a telescopic main board 1231 and a material receiving baffle 1232 connected to one end of the telescopic main board 1231, and the material receiving baffle 1232 is arranged opposite to the flip inclined board 122. In this way, the flip inclined board 122 transfers the material on the flip inclined board 122 to the telescopic main board 1231 and abuts against the material receiving baffle 1232 by flipping. Furthermore, the third driving component 124 is arranged at the bottom of the telescopic main board 1231. The material receiving telescopic plate 123 can move relative to the flip inclined board 122, and then adjust the distance between the material receiving baffle 1232 and the flip inclined board 122 to meet the needs of material collection and ensure the material receiving space.

[0067] Furthermore, the material receiving baffle 1232 and the flip inclined plate 122 are both inclined relative to the telescopic main board 1231, and the material receiving baffle 1232 and the flip inclined plate 122 are inclined in opposite directions relative to the telescopic main board 1231. Specifically, the angle formed between the material receiving baffle 1232 and the telescopic main board 1231 is greater than 90°.

[0068] Furthermore, when the material receiving telescopic plate 123 is in the return state, the telescopic main plate 1231 is at least partially located below the flip inclined plate 122. Figure 7 shown.

[0069] See also Figure 5 Further, the material receiving assembly 120 further includes a first material receiving side plate 126 and a second material receiving side plate 127, which are respectively arranged on both sides of the flip inclined plate 122. This prevents the material on the flip inclined plate 122 from shifting left and right.

[0070] In some embodiments, the receiving assembly 120 further includes a receiving guide plate 128, which is disposed above the flip inclined plate 122 and is respectively connected to the first receiving side plate 126 and the second receiving side plate 127, and the receiving guide plate 128 and the flip inclined plate 122 together constitute a receiving inclined plate. In this way, the material is transferred to the flip inclined plate 122 through the receiving guide plate 128.

[0071] In some embodiments, the material receiving assembly 120 further includes a first material incoming sensor 129, which is disposed on the flip inclined plate 122 and is used to sense the incoming material. The flip inclined plate 122 is used to flip when the first material incoming sensor 129 receives an incoming material signal. In addition, the first material incoming sensor 129 is also used to count the incoming material to count the amount of material collected on the material receiving telescopic plate 123. Furthermore, the flip inclined plate 122 is provided with a mounting hole for mounting the first material incoming sensor 129.

[0072] See also Figure 3 In some embodiments, the loading assembly 110 includes a conveyor belt 111 and a second incoming material sensor 112, and the second incoming material sensor 112 is arranged on the conveyor belt 111 for sensing incoming materials. The sorting plate 131 is used to perform a sorting action when the second incoming material sensor 112 receives an incoming material signal. Furthermore, the conveyor belt 111 is a belt transmission component.

[0073] See also Figure 1 One embodiment of the present invention relates to a bagging device 200 of an embodiment, including a bag opening mechanism 210, a bag holding mechanism 220 and a bagging mechanism 230.

[0074] The bag opening mechanism 210 includes a positioning adsorption component 211 and a bag opening adsorption component 212. The positioning adsorption component 211 is used to adsorb the bottom layer of the packaging bag, and the bag opening adsorption component 212 is used to adsorb the surface layer of the packaging bag on the positioning adsorption component 211 to open the bag mouth of the packaging bag.

[0075] See also Figure 8 , Fig.10 and Fig.11 The bag-opening mechanism 220 includes a bag-opening opening component 221 and a bag-opening pressing component 222. The bag-opening opening component 221 is used to act on the inner wall of the packaging bag with the bag opening opened to open the bag opening, and the bag-opening pressing component 222 is used to act on the outer wall of the packaging bag to press the packaging bag.

[0076] The bagging mechanism 230 is used to obtain the material to be packaged and put the material into the packaging bag with the bag opening opened. Fig. 9 shown.

[0077] When the bagging device is working, the positioning adsorption component 211 and the bag opening adsorption component 212 of the bag opening mechanism 210 cooperate with each other. The positioning adsorption component 211 adsorbs the bottom layer of the packaging bag to position it, and the bag opening adsorption component 212 adsorbs the surface layer of the packaging bag on the positioning adsorption component 211. The adsorption action area is large and the adsorption is stable, so that the bag mouth of the packaging bag can be smoothly opened laterally. When the bag mouth is in an open state, the bag mouth opening component 221 in the bag holding mechanism 220 works, enters the inner wall of the packaging bag and acts on the inner wall of the packaging bag to open the bag mouth of the packaging bag, and the bag mouth pressing component 222 acts on the outer wall of the packaging bag to press the packaging bag. In this way, the bag mouth opening component 221 and the bag mouth pressing component 222 keep the packaging bag in an open state and will not loosen. Further, the bagging mechanism 230 obtains the material to be packaged and puts the material into the packaging bag with the bag mouth opened. In summary, the bagging device 200 realizes the processes of bag opening, bag holding and automatic bagging, avoids the problem of low efficiency of manual operation and greatly improves work efficiency.

[0078] It can be understood that after the bag opening opening component 221 in the bag opening mechanism 220 opens the bag opening of the packaging bag, and the bag opening pressing component 222 presses the packaging bag, the positioning adsorption component 211 and the bag opening adsorption component 212 can continue to work or not work. In some examples, the positioning adsorption component 211 can continue to work to continue to position the packaging bag; the bag opening adsorption component 212 can not work to reserve operating space for the bag opening mechanism 220.

[0079] Please continue reading Figure 8 In some embodiments, the positioning adsorption component 211 has an adsorption table with adsorption holes. The bag opening adsorption component 212 includes a bag opening suction cup 2121 and a bag opening suction cup moving component 2122. The bag opening suction cup moving component 2122 is connected to the bag opening suction cup 2121 and is used to drive the bag opening suction cup 2121 to move closer to or away from the adsorption table.

[0080] Furthermore, the bag opening suction cup 2121 is arranged above the adsorption table, and the bag opening suction cup moving part 2122 is used to drive the bag opening suction cup 2121 to move up and down. In this way, the bag opening suction cup 2121 moves downward and approaches the adsorption table to adsorb the surface layer of the packaging bag, and after adsorption, drives the surface layer of the packaging bag to move upward and away from the adsorption table, so that the bottom layer of the packaging bag is separated from the surface layer, thereby opening the side opening of the packaging bag.

[0081] Furthermore, an incoming material sensor (not shown) is installed on the adsorption table to sense the incoming material.

[0082] Furthermore, the positioning adsorption assembly 211 also includes a vacuum pumping component (not shown), which is connected to the adsorption table to form a vacuum environment in the adsorption hole. Furthermore, the bag opening adsorption assembly 212 also includes a vacuum pumping component (not shown) connected to the bag opening suction cup 2121 and used for vacuuming.

[0083] Furthermore, the bag opening suction cup moving component 2122 can be a driving component such as a cylinder.

[0084] Please continue reading Fig.10 In some embodiments, the bag opening opening assembly 221 includes a first opening plate 2211 and a second opening plate 2212 that are arranged opposite to each other, and the first opening plate 2211 and the second opening plate 2212 can be close to or far away from each other. In this way, the distance between the first opening plate 2211 and the second opening plate 2212 can be adjusted according to the size of the bag opening to meet the size requirements of the bag opening.

[0085] Specifically, the first opening plate 2211 and the second opening plate 2212 are vertically arranged, so that the first opening plate 2211 and the second opening plate 2212 act on the side of the packaging bag, and the bag opening mechanism 210 absorbs the upper and lower surfaces of the packaging bag.

[0086] Please continue reading Fig.11 Furthermore, the bag opening pressing assembly 222 includes a first pressing member 2221 and a second pressing member 2222 that can move closer to or farther from each other. The first pressing member 2221 and the second pressing member 2222 are respectively arranged on the outer side of the first opening plate 2211 and the outer side of the second opening plate 2212, so that a pressing space is formed between the first pressing member 2221 and the first opening plate 2211, and between the second pressing member 2222 and the second opening plate 2212. In this way, the packaging bag is sleeved on the outer side of the first opening plate 2211 and the second opening plate 2212, and is located on the inner side of the first pressing member 2221 and the second pressing member 2222, and plays the role of opening and pressing the packaging bag at the same time.

[0087] Please continue reading Fig.10 or Fig.11 In some embodiments, the bag-opening mechanism 220 further includes a mounting plate 223, and the bag-opening assembly 221 further includes an opening power component 2213 for driving the first opening plate 2211 and the second opening plate 2212 to move closer to or away from each other, and the opening power component 2213 is connected to the mounting plate 223; the first clamping member 2221 and the second clamping member 2222 are connected to the mounting plate 223.

[0088] Further, the expansion power component 2213 is a telescopic cylinder, specifically, the first expansion plate 2211 and the second expansion plate 2212 are each connected to an expansion power component 2213, so as to move respectively under the drive of the expansion power component 2213. Specifically, the first pressing member 2221 and the second pressing member 2222 can also be a telescopic cylinder.

[0089] In some embodiments, the mounting plate 223 has a mounting notch, the first support plate 2211 and the second support plate 2212 are installed in the mounting notch, and the extension directions of the first support plate 2211 and the second support plate 2212 are perpendicular to the plane where the mounting plate 223 is located.

[0090] Specifically, the first opening plate 2211 and the second opening plate 2212 each include a first end and a second end opposite to each other. The first end is an insertion end for inserting into the bag opening of the packaging bag; the second end is connected to the opening power component 2213. More specifically, the opening power component 2213 is located on the surface of the mounting plate 223 close to the second end, and the first pressing member 2221 and the second pressing member 2222 are located on the surface of the mounting plate 223 close to the first end.

[0091] Please continue reading Fig.10 In some embodiments, the bag-supporting mechanism 220 further includes a bag-supporting moving assembly 224, which is connected to the mounting plate 223 and is used to drive the first opening plate 2211 and the second opening plate 2212 to move in a first direction and a second direction, wherein the first direction is the same as an extension direction of the first opening plate 2211, and the second direction and the first direction are perpendicular to each other and are both horizontal directions.

[0092] Furthermore, the bag-supporting moving component 224 may be a cross linear motion linear module, or a combination of two linear cylinders, or other components that can achieve movement in two directions relative to each other.

[0093] Please continue reading Fig.10 In some embodiments, the bagging device 200 further includes a bagged product moving mechanism 240, which is used to move the bagged product on the positioning and adsorption component 211. After the current packaging bag has been filled with materials, the bagged product moving mechanism 240 moves the bagged product on the positioning and adsorption component 211, so that the bagged product enters the next process and prepares for the next packaging bag to enter the positioning and adsorption component 211.

[0094] Furthermore, the bagged product moving mechanism 240 includes a moving plate 241, which can move in the third direction and the second direction relative to the positioning adsorption component 211, and the third direction is the vertical direction. When it is necessary to move the bagged product on the positioning adsorption component 211, the moving plate 241 moves vertically downward relative to the positioning adsorption component 211, moves to a preset position, and then moves in the second direction, and at the same time drives the bagged product to move in the second direction to leave the positioning adsorption component 211.

[0095] Further, the adsorption platform of the positioning adsorption assembly 211 and the bag sealing platform 310 (see Fig.13 ) are arranged in sequence in the second direction, such as Figure 2 The movable plate 241 can move relative to the positioning adsorption component 211 in the third direction to adjust the height of the movable plate 241; the movable plate 241 can move relative to the positioning adsorption component 211 in the second direction to the bag sealing platform 310 to facilitate the subsequent bag sealing process.

[0096] It is understandable that when the bagged product moving mechanism 240 is working, the positioning and adsorption component 211 is not working.

[0097] Furthermore, the bagged product moving mechanism 240 also includes a paddle driving assembly 242 , which is connected to the moving paddle 241 and is used to drive the moving paddle 241 to move in a third direction relative to the positioning adsorption assembly 211 .

[0098] Furthermore, the paddle driving assembly 242 is connected to the bag-supporting moving assembly 224, so that the moving paddle 241 can move in the first direction, the second direction and the third direction relative to the positioning adsorption assembly 211. In this way, the moving paddle 241 can move synchronously with the bag-supporting mechanism 220 in the first direction and the second direction, so that when the moving paddle 241 moves to the bag sealing platform 310, the bag opening opening assembly 221 and the bag opening pressing assembly 222 also move synchronously with the bagged product to the bag sealing platform 310, and continue to play the role of supporting the bag, so as to facilitate the product pressing mechanism 320 (see Fig.13 ) of the clamping plate 322 (see Fig.13 ) extends into the packaging bag in the sealing area and presses the product in the packaging bag.

[0099] Please continue reading Figure 8 and Fig. 9 In some embodiments, the bagging device 200 further includes a bag taking mechanism 250, which includes a bag taking lifting platform 251 and a bag taking suction component 252. The bag taking lifting platform 251 is used to carry the packaging bag and can be lifted and lowered; the bag taking suction component 252 is used to absorb the packaging bag on the bag taking lifting platform 251 and transfer the packaging bag to the positioning suction component 211.

[0100] Further, the bag taking lifting platform 251 and the adsorption table surface in the positioning adsorption component 211 are sequentially arranged in the first direction. It can be understood that the bag taking mechanism 250 also includes a lifting transmission component, and the bag taking lifting platform 251 can be lifted and lowered by the lifting transmission component.

[0101] Please continue reading Fig. 9 Further, the bag taking suction component 252 includes a bag taking suction cup 2521 and a bag taking suction cup moving component 2522. The bag taking suction cup moving component 2522 is connected to the bag taking suction cup 2521 and is used to drive the bag taking suction cup 2521 to move in the vertical direction to approach or move away from the bag taking lifting platform 251, and is also used to drive the bag taking suction cup 2521 to move in the first direction to transfer the material to the driving bag taking suction cup 2521. Specifically, the bag taking suction cup moving component 2522 can be a component that can realize movement in two directions, such as a cross linear motion linear module or a combination of two linear cylinders.

[0102] Furthermore, the bag taking mechanism 250 also includes a low-level sensor (not shown), a material sensor (not shown) and a high-level sensor (not shown) which are arranged in sequence from bottom to top in the vertical direction. The material sensor is used to sense whether there is material on the bag taking lifting platform 251, the low-level sensor is used to sense the lowest position that the material discharge plate of the bag taking lifting platform 251 can reach, and the high-level sensor is used to sense the highest position that the packaging bag stack on the material discharge plate of the bag taking lifting platform 251 can reach. In this way, as the packaging bags are taken, the bag taking lifting platform 251 is controlled to rise, so that when the packaging bags on the material discharge plate of the bag taking lifting platform 251 rise to the taking height, the bag taking adsorption component 252 works to take the bags. It can be understood that each time the bag is taken, the top packaging bag of the bag taking lifting platform 251 can be controlled to be at the same taking height.

[0103] Please continue reading Fig.12 In some embodiments, the bagging mechanism 230 includes a clamping assembly 231. The clamping assembly 231 includes a first clamping member 2311 and a second clamping member 2312 that can move closer to or farther from each other, and is used to clamp the material to be packaged and put the clamped material into the packaging bag with the bag opening opened.

[0104] Furthermore, the clamping assembly 231 also includes a clamping power component 2313 for driving the first clamping member 2311 and the second clamping member 2312 to move closer to or away from each other. Further, the clamping power component 2313 is a telescopic cylinder. Specifically, the first clamping member 2311 and the second clamping member 2312 are each connected to a clamping power component 2313 to move under the drive of the clamping power component 2313.

[0105] Specifically, the clamping power component 2313 is connected to the inner side of the first clamping member 2311 and the second clamping member 2312, and the main bodies of the two clamping power components 2313 are relatively fixed. By controlling the extension or contraction of the clamping power component 2313, the distance between the first clamping member 2311 and the second clamping member 2312 can be controlled. In a specific example, according to the distance between the first clamping member 2311 and the second clamping member 2312, there are three levels of position states between the first clamping member 2311 and the second clamping member 2312. Level 1 position state: Both clamping power components 2313 connected to the first clamping member 2311 and the second clamping member 2312 are in a retracted state, and the distance between the first clamping member 2311 and the second clamping member 2312 is the smallest. At this time, the material can be tightly clamped for transportation. Secondary position state: When the material has been fed into the packaging bag, one of the two clamping power components 2313 is in an extended state, and the distance between the first clamping component 2311 and the second clamping component 2312 is larger than the size of the material, just enough to loosen the material, but not larger than the width of the packaging bag. Third level position state: The two clamping power components 2313 are in an extended state, and the distance between the first clamping component 2311 and the second clamping component 2312 is the largest, which is convenient for clamping the material.

[0106] Furthermore, the bagging mechanism 230 also includes a gripping moving assembly 232, which drives the gripping assembly 231 to move in the first direction, the second direction and the third direction, and is flexible in movement, so as to facilitate the acquisition of the material to be packaged and drive the material to move and transfer and load it into the packaging bag with the bag opening opened. Furthermore, the gripping moving assembly 232 can be an XYZ linear module.

[0107] Specifically, the bagging mechanism 230 is disposed adjacent to the material receiving telescopic plate 123 and the adsorption platform of the stacking and receiving device 100. The clamping assembly 231, under the action of the clamping moving assembly 232, conveniently and flexibly clamps the sorted materials from the material receiving telescopic plate 123, and transfers the materials to the packaging bag with the bag opening opened on the adsorption platform, thereby bagging the materials.

[0108] See also Fig.13 An embodiment of the present invention provides a bag sealing device 300 of an embodiment, including a bag sealing platform 310, a product pressing mechanism 320 and a bag closing mechanism 330.

[0109] The bag sealing platform 310 has a bag sealing area for placing packaging bags with their openings opened. The bag sealing area is provided with a bag opening closing hole 311 and a bag sealing hole 312 .

[0110] The product pressing mechanism 320 is used to press the product in the packaging bag located in the bag sealing area. In this way, the product in the packaging bag is squeezed by the product pressing mechanism 320, and the product in the packaging bag is reduced for easy packaging.

[0111] The bag opening closing mechanism 330 includes a first bag opening press 331 and a second bag opening press 332. The first bag opening press 331 is arranged on one side of the bag sealing area of ​​the bag sealing platform 310, and the second bag opening press 332 is arranged on the side away from the bag sealing area. The second bag opening press 332 can pass through the bag opening closing hole 311 and cooperate with the first bag opening press 331 to close the bag opening at the bag opening closing hole 311.

[0112] The bag sealing mechanism 340 has a bag sealing pressing plate 341; the bag sealing pressing plate 341 is arranged on the side away from the bag sealing area, and can be turned over relative to the bag sealing platform 310 and pass through the bag sealing hole 312 to fold the end of the bag opening toward one side of the bag opening closing hole 311 to seal.

[0113] The bag sealing device 300 is used to seal a packaging bag with an open bag mouth filled with products, and further used to seal a packaging bag with an open bag mouth filled with products and opened by the bag support mechanism 220. First, the packaging bag with an open bag mouth is placed on the bag sealing area of ​​the bag sealing platform 310, and then the bag sealing device 300 starts to work. The product pressing mechanism 320 works to press the product in the packaging bag on the bag sealing area. Then the bag mouth closing mechanism 330 works, and the second bag mouth pressing member 332 can pass through the bag mouth closing hole 311 and cooperate with the first bag mouth pressing member 331, so that the bag mouth on the bag sealing area is closed at the bag mouth closing hole 311. After the bag mouth is closed, the bag sealing pressing plate 341 of the bag sealing mechanism 340 turns over relative to the bag sealing platform 310 and passes through the bag sealing hole 312, driving the end of the bag mouth on the bag sealing area of ​​the bag sealing platform 310 to fold toward one side of the mouth closing hole 311, so that the bag mouth is sealed. In this way, the bag sealing device 300 automatically realizes the processes of product compression, bag mouth closing and sealing of the packaging bag, thus avoiding the problems of high manual labor intensity and low work efficiency, and greatly improving work efficiency.

[0114] In some embodiments, the product pressing mechanism 320 includes a top plate 321 and a pressing plate 322. The top plate 321 is disposed on the bag sealing platform 310, and the bag opening closing hole 311 is located between the top plate 321 and the bag sealing hole 312. The pressing plate 322 can move relative to the top plate 321, and is used to extend from the bag opening into the packaging bag located in the bag sealing area and drive the product in the packaging bag to be pressed against the top plate 321. In this way, the product in the packaging bag is pressed between the top plate 321 and the pressing plate 322, and is preferably located between the top plate 321 and the bag opening closing hole 311, so that the bag opening of the packaging bag is located correspondingly at the bag opening closing hole 311, thereby facilitating the bag opening closing mechanism 330 to close the bag opening.

[0115] Further, the movement direction of the clamping plate 322 relative to the top plate 321 is the first direction. Further, the product clamping mechanism 320 also includes a driving component connected to the clamping plate 322 and used to drive the clamping plate 322 to move relative to the top plate 321. It can be understood that the driving component can be a driving component that can achieve linear motion, such as a cylinder, a motor, etc.

[0116] See also Fig.14 Furthermore, the pressing plate 322 and the bag sealing platform 310 are not in direct contact, but have a certain height difference.

[0117] See also Fig.14 In some embodiments, the maximum height of the second bag opening press member 332 in the bag opening closing mechanism 330 that can protrude from the bag opening closing hole 311 is not higher than the height difference between the pressing plate 322 and the bag sealing platform 310 when the pressing plate 322 is pressed on the top plate 321. In this way, while the pressing plate 322 presses the product, the second bag opening press member 332 can pass through the bag opening closing hole 311 to act on the bag opening area of ​​the packaging bag that is not filled with the product, and at the same time play a role in blocking the product in the packaging bag. At this time, the pressing plate 322 can move away from the top plate 321 to reset, and the compressed product in the packaging bag will not rebound; and the bag support mechanism 220 and the bagged product moving mechanism 240 reset for the next bagging. Afterwards, with the cooperation of the first bag opening press member 331, the upper and lower surfaces of the bag opening are squeezed and closed at the bag opening closing hole 311.

[0118] Furthermore, the second bag opening pressing piece 332 is a pressing plate with a large contact area, which is convenient for blocking the product in the packaging bag; the first bag opening pressing piece 331 is a pressing rod.

[0119] Further, the second bag opening press member 332 and the first bag opening press member 331 can independently move relative to the bag sealing platform 310 to approach or move away from the bag sealing platform 310. Further, the second bag opening press member 332 and the first bag opening press member 331 are both arranged corresponding to the bag opening closing hole 311.

[0120] Furthermore, the bag opening closing mechanism 330 further includes a first pressing drive assembly 333 and a second pressing drive assembly 334.

The second direction and the first direction are perpendicular to each other and are both horizontal directions, and the third direction is a vertical direction. The second pressing drive assembly 334 is connected to the second bag opening pressing member 332, and is used to drive the second bag opening pressing member 332 to move in the third direction relative to the bag sealing platform 310.

[0121] It is understood that the first pressing drive assembly 333 can be a cross linear motion linear module, or a combination of two linear cylinders, etc., which can realize movement in two directions. The second pressing drive assembly 334 can be a drive assembly such as a cylinder, a motor, etc., which can realize linear motion.

[0122] In some embodiments, the bag mouth closing hole 311 is connected to the bag sealing hole 312, so that the bag sealing pressing plate 341 can better act on the bag mouth position of the bag mouth closure, so that the bag mouth closure position is folded to achieve folding and sealing. Further, the extending directions of the bag mouth closing hole 311 and the bag sealing hole 312 are perpendicular to each other. Specifically, the extending direction of the bag mouth closing hole 311 is the second direction, and the extending direction of the bag sealing hole 312 is the first direction.

The bag sealing plate 341 can be turned over relative to the bag sealing platform 310 and pass through the bag sealing hole 312, so that the plate body 3411 and the bag sealing platform 310 are perpendicular to each other and the folding portion 3412 is folded toward one side of the bag opening closing hole 311 for sealing. In this way, it can be ensured that the bag opening of the packaging bag is folded up and attached to the side of the packaging bag, so as to facilitate the adhesive tape to be attached.

[0124] Furthermore, the folding portion 3412 is an arc-shaped structure.

[0125] Specifically, the pressing plate body 3411 is provided with a plurality of parallel and spaced grooves at one end close to the folding portion 3412; correspondingly, the bag sealing holes 312 on the bag sealing platform 310 are correspondingly provided with a plurality of parallel and spaced sub-bag sealing holes.

[0126] Further, the bag sealing mechanism 340 further includes a platen driving assembly 342, which is connected to the bag sealing platen 341 and is used to drive the bag sealing platen 341 to flip relative to the bag sealing platform 310.

Specifically, the bag sealing mechanism 340 further includes a fixed plate 343, the bag sealing platen 341 is hinged on the fixed plate 343, and both ends of the platen driving assembly 342 are respectively connected to the fixed plate 343 and the bag sealing platen 341, so as to drive the bag sealing platen 341 to flip relative to the fixed plate 343. Further, the fixed plate 343 is located below the bag sealing platform 310 and is parallel to the bag sealing platform 310.

[0127] Specifically, the second pressing driving assembly 334 may also be disposed on the fixing plate 343 .

[0128] Please continue reading Fig.15 In some embodiments, the bag sealing device 300 further includes a bag opening gluing mechanism 350. The bag opening gluing mechanism 350 includes a tape holder 351 for placing adhesive tape and adhesive tape cutting teeth 352 provided on the tape holder 351. The tape holder 351 can rotate relative to the bag sealing platform 310, so that the adhesive tape on the tape holder 351 that is glued to the sealing of the packaging bag is cut off. When working, the tape holder 351 is close to the sealing position of the packaging bag, so that the adhesive tape on the tape holder 351 is glued to the sealing position, and then the tape holder 351 rotates relative to the bag sealing platform 310, so that the adhesive tape glued to the sealing of the packaging bag is cut off, and one gluing is completed. When multiple gluing is required, it can be performed multiple times.

[0129] Furthermore, the bag opening gluing mechanism 350 further includes a tape holder rotating assembly 353, which is connected to the tape holder 351 and is used to drive the tape holder 351 to rotate relative to the bag sealing platform 310.

[0130] Furthermore, the bag opening gluing mechanism 350 also includes a tape holder displacement assembly 354, which is connected to the tape holder 351 and is used to drive the tape holder 351 to move in the first direction, the second direction, and the third direction. This allows the tape holder 351 to flexibly adjust its position to meet the position requirements of the packaging bag sealing. Specifically, the tape holder displacement assembly 354 can be a driving assembly such as an XYZ linear module.

[0131] Please continue reading Fig.15 In some embodiments, the bag sealing device 300 further includes a bag sealing product shifting mechanism 360. The bag sealing product shifting mechanism 360 has a material shifting push rod 361, which can move relative to the bag sealing platform 310 and is used to drive the bag sealing product on the bag sealing platform 310 to move. In this way, the bag sealing product on the bag sealing platform 310 that has been sealed is removed from the bag sealing platform 310, so that the bag sealing platform 310 can be used for the next bag sealing.

[0132] Furthermore, the material transfer push rod 361 can move in a second direction relative to the bag sealing platform 310 to drive the bagged product on the bag sealing platform 310 to move. Furthermore, the bag sealing platform 310 is provided with a material transfer hole 313, preferably, the material transfer hole 313 is located between the top plate 321 and the bag mouth closing hole 311.

[0133] Furthermore, the material transfer push rod 361 is disposed on the side away from the bag sealing area, and can move in the third direction relative to the bag sealing platform 310, and then pass through the material transfer hole 313. In this way, the bagged product on the bag sealing platform 310 can be acted on. Then, the material transfer push rod 361 moves in the second direction relative to the bag sealing platform 310, driving the bagged product on the bag sealing platform 310 to move, so as to be removed from the bag sealing platform 310.

[0134] Further, the bagging product shifting mechanism 360 also includes a material transfer push rod driving assembly 362, which is connected to the material transfer push rod 361 and is used to drive the material transfer push rod 361 to move in the second direction and the third direction.

When working, the stacking and collecting device 100 stacks and collects the materials to be packaged, and the bagging device 200 opens the bag mouth of the packaging bag and puts the materials collected on the stacking and collecting device 100 into the packaging bag with the bag mouth opened. The packaging bag with the bag mouth opened is placed on the bag sealing area 310 of the bag sealing platform, and the bag sealing device 300 starts to work. The product pressing mechanism 320 works to press the product in the packaging bag on the bag sealing area. Then the bag mouth closing mechanism 330 works, and the second bag mouth pressing member 332 can pass through the bag mouth closing hole 311 and cooperate with the first bag mouth pressing member 331, so that the bag mouth on the bag sealing area is closed at the bag mouth closing hole 311. After the bag mouth is closed, the bag sealing pressing plate 341 of the bag sealing mechanism 340 turns over relative to the bag sealing platform 310 and passes through the bag sealing hole 312, driving the end of the bag mouth on the bag sealing area of ​​the bag sealing platform 310 to fold toward one side of the mouth closing hole 311, so that the bag mouth is sealed.
