Description

Technical Field

[0001] This invention relates to the field of material packaging technology, and in particular to a material bagging device and material packaging equipment. Background Technology

[0002] Currently, in the sales process of bagged products, to stimulate consumption and increase sales, manufacturers often include cards inside the packaging bags during production. These cards contain prize-winning information and / or cartoon images, or other information designed to incentivize consumption. Existing technology typically involves manually inserting the cards into the packaging bags. Specifically, existing technologies often utilize automated packaging lines to package materials such as areca nuts, resulting in bagged products. These automated packaging lines are equipped with a material-feeding device that inserts an inner bag containing the material into an outer bag. Then, a person manually inserts the card into the outer bag, creating a double-layered bagged product. This satisfies the requirements for food packaging safety, airtightness, and non-toxicity, and also allows for the printing of desired designs or promotional content on the outer bag. However, manual card insertion is inefficient and cannot meet the requirements of automated packaging.

[0003] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a material bagging device and a material packaging equipment to solve the problem that manual card loading is inefficient and cannot meet the requirements of automated packaging.

The first groove extends along the first horizontal direction. The second groove is located at the end of the first groove away from the carrier along the first horizontal direction and extends downward in the vertical direction.

[0046] Example 1

[0047] This embodiment provides a material packaging device, which includes a material bag-feeding device. In this embodiment, the material bag-feeding device can insert an inner bag containing material into an outer bag, thereby forming a double-layer packaging bag. Furthermore, the material bag-feeding device can also insert a card into the outer bag during the process of inserting the inner bag into the outer bag. In this embodiment, the material is betel nut or other food products. Of course, in other optional embodiments, the material can also be other products that need to be packaged with packaging bags. This embodiment does not impose specific limitations on this.

[0048] The following text refers to Figures 1 to 18 The material bagging device in this embodiment will be described, wherein the material bagging device inserts the inner bag 300 into the outer bag through the inner bag inserting mechanism, thereby forming a double-layer packaging bag.

[0049] In this embodiment, the inner bag insertion mechanism includes a carrier 110, a first pusher 120, and a guide module 130. The carrier 110 has an internal receiving cavity 111 configured to receive an inner bag 300 containing material. A discharge port 1121 is provided on the bottom plate 112 of the carrier 110. The first pusher 120 can extend from the top of the carrier 110 into the receiving cavity 111 and push the inner bag 300 out of the discharge port 1121, thereby pushing the inner bag 300 into an outer bag placed below the carrier 110. The guide module 130 is installed at the bottom of the carrier 110 and includes a guide module along a first water... A first guide plate 131 and a second guide plate 132 are arranged opposite each other in the horizontal direction. The first guide plate 131 and the second guide plate 132 surround the outer periphery of the discharge port 1121. The end of the first guide plate 131 away from the carrier 110 and the end of the second guide plate 132 away from the carrier 110 can move away from each other and form an opening 133. When the inner bag 300 passes through the opening 133, the first guide plate 131 and the second guide plate 132 cover the outer periphery of the inner bag 300, thereby limiting the inner bag 300 to prevent the inner bag 300 from shaking in the horizontal direction, and thus ensuring that the inner bag 300 is accurately put into the outer bag.

[0050] That is, in this embodiment, the inner bag 300 is put into the outer bag through the inner bag insertion mechanism. The whole process does not require manual intervention and is highly efficient, thus meeting the requirements of automated packaging.

[0051] Based on the above description, in this embodiment, the carrier 110 includes a bottom plate 112. In addition to the bottom plate 112, the carrier 110 also includes a top plate 113 and a frame 114. The top plate 113 and the bottom plate 112 are both mounted on the frame 114. The top plate 113, the frame 114, and the bottom plate 112 together form a receiving cavity 111. The carrier 110 has a first inlet 115 on one side along the horizontal direction. In this embodiment, the first inlet 115 is opened along the first horizontal direction and is formed between the top plate 113 and the bottom plate 112. The inner bag 300 can be moved into the receiving cavity 111 through the first inlet 115. It can be understood that the inner bag 300 can be transported into the receiving cavity 111 by a robot or other conveying mechanism. This embodiment does not impose specific limitations on this.

[0052] It is worth noting that the inner bag 300 containing materials needs to be sealed first. Specifically, the top of the inner bag 300 is formed as a closed portion 310. Based on packaging requirements, the inner bag 300 needs to enter the receiving cavity 111 in an upright position. In this embodiment, the height of the first inlet 115 is less than the height of the inner bag 300, so that the closed portion 310 at the top of the inner bag 300 is bent. That is, when the inner bag 300 enters the receiving cavity 111 through the first inlet 115, the closed portion 310 at the top of the inner bag 300 bends downward due to the obstruction of the top plate 113. This prevents the closed portion 310 at the top of the inner bag 300 from being located between the sealing portion at the top of the outer bag when the inner bag 300 is subsequently pushed into the outer bag by the first pusher 120. This ensures that the sealing performance of the double-layer packaging bag formed after the outer bag is sealed meets the requirements.

[0053] Furthermore, the inner bag insertion mechanism also includes a push rod 140, which can push the top plate 113 downward in the vertical direction, thereby allowing the top plate 113 to move downward relative to the frame 114, and further bend the closing part 310 at the top of the inner bag 300 downward, thereby preventing the closing part 310 at the top of the inner bag 300 from returning to the sealing part at the top of the outer bag due to the recovery deformation when the inner bag 300 is subsequently pushed into the outer bag by the first push block 120.

[0054] Preferably, in this embodiment, a first mounting member 1141 is fixedly connected to the frame 114. The first mounting member 1141 is located below the top plate 113, and a first spring 116 is connected between the first mounting member 1141 and the top plate 113. The first spring 116 extends vertically. A first guide rod 1131 is fixedly connected to the top plate 113. The first guide rod 1131 extends vertically. The first mounting member 1141 is sleeved on the outer periphery of the first guide rod 1131. Specifically, the first mounting member 1141... Component 1141 includes a first mounting block 11411 and a first sleeve 11412. The first mounting block 11411 is fixedly connected to the frame 114, and the first sleeve 11412 is fixedly connected to the first mounting block 11411. The first sleeve 11412 is sleeved on the outer periphery of the first guide rod 1131. When the push rod 140 pushes the top plate 113 to descend in the vertical direction, the first spring 116 undergoes elastic deformation, thereby having elastic potential energy to reset the top plate 113 when the push rod 140 moves away from the top plate 113.

[0055] For example, in this embodiment, the inner bag insertion mechanism further includes a frame 150, on which a first drive unit 151 is installed. The first drive unit 151 is used to drive the first push block 120 to move in the vertical direction. A second drive unit 152 is also installed on the frame 150, which is used to drive the push rod 140 to move in the vertical direction.

[0056] It is understood that both the first drive unit 151 and the second drive unit 152 can be selected as linear drive structures such as cylinders, electric cylinders, or electric push rods, and no specific restrictions are imposed on this embodiment.

[0057] Furthermore, a pressure plate 121 is provided at the bottom of the first push block 120. The pressure plate 121 is located on the side of the first push block 120 along the horizontal direction near the first inlet 115. Specifically, in this embodiment, the pressure plate 121 is located on the side of the first push block 120 along the first horizontal direction near the first inlet 115. During the descent of the first push block 120, the pressure plate 121 can first contact the inner bag 300, and the pressure plate 121 contacts the closing part 310 of the inner bag 300. Thus, the closing part 310 of the inner bag 300 can be bent downward again before the first push block 120 pushes the inner bag 300, thereby further ensuring that after the inner bag 300 is subsequently pushed into the outer bag, the closing part 310 at the top of the inner bag will not return to the sealing part at the top of the outer bag.

[0058] Furthermore, the top plate 113 and the frame 114 form a second inlet 117. The first pusher 120 and the pressure plate 121 extend into the receiving cavity 111 through the second inlet 117. The pressure plate 121 and the first pusher 120 are provided with guide grooves 122, and the top plate 113 is provided with guide blocks 1132. The guide grooves 122 extend vertically, and the guide blocks 1132 can slide within the guide grooves 122 along the extension direction of the guide grooves 122, thereby providing guidance for the movement of the first pusher 120 and the pressure plate 121, and thus ensuring that the inner bag 300 and the card can be accurately pushed into the outer bag.

[0059] In addition, in this embodiment, the frame 114 includes a side plate 1142, a first limiting plate 1143, and a second limiting plate 1144. A third driving unit 11421 is mounted on the side plate 1142. The first limiting plate 1143 and the second limiting plate 1144 are arranged at intervals along a second horizontal direction perpendicular to the first horizontal direction. The third driving unit 11421 can drive the first limiting plate 1143 and the second limiting plate 1144 to move relative to or away from each other along the second horizontal direction. The bottom plate 112 The top plate 113, side plate 1142, first limiting plate 1143 and second limiting plate 1144 together form the receiving cavity 111. Since the first limiting plate 1143 and the second limiting plate 1144 can move relative to or away from each other along the second horizontal direction, when the inner bag 300 is placed in the receiving cavity 111, the first limiting plate 1143 and the second limiting plate 1144 can correct the position of the inner bag 300, thereby ensuring that the inner bag 300 is aligned with the discharge port 1121.

[0060] It is understandable that the inner bag 300 is placed on the base plate 112, and the bottom contour of the inner bag 300 is larger than the contour of the discharge port 1121. When the first push block 120 pushes against the inner bag 300, the inner bag 300 can undergo local deformation, thereby passing through the discharge port 1121.

[0061] It is worth noting that in this embodiment, the third drive unit 11421 is a bidirectional cylinder. Of course, in other optional embodiments, the third drive unit 11421 may also be composed of two separate linear drive structures. The two linear drive structures are used to drive the first limiting plate 1143 and the second limiting plate 1144 to move, respectively. The linear drive structure may be a cylinder, an electric cylinder, or an electric push rod, etc. This embodiment does not impose specific restrictions on this.

[0062] It should be noted that in this embodiment, the carrier 110 is provided with two or more accommodating cavities 111. In other words, the description is based on a first limiting plate 1143 and a second limiting plate 1144 as a set of limiting structures. The carrier 110 in this embodiment is provided with two or more sets of limiting structures, which are arranged at intervals along the second horizontal direction. Each accommodating cavity 111 is provided with a set of limiting structures. Similarly, each accommodating cavity 111 is provided with a first push block 120, and each accommodating cavity 111 is provided with a first driving part 151.

[0063] In addition, the vehicle 110 is equipped with only one top plate 113, one bottom plate 112 and one side plate 1142, and all limiting structures share the same top plate 113, the same bottom plate 112 and the same side plate 1142.

[0064] Based on the above, this embodiment is provided with two or more first push blocks 120 and two or more guide modules 130, and each receiving cavity 111 is provided with a first push block 120 and a guide module 130.

[0065] Furthermore, the ends of the first guide plate 131 and the second guide plate 132 that are away from the carrier 110 can approach each other and form a pointed tip 134. The inner bag insertion mechanism also includes a mounting frame 160 and a second pusher block 170. The frame 114 is slidably connected to the mounting frame 160 in the vertical direction. The second drive unit 152 can drive the push rod 140 and the second pusher block 170 to move in the vertical direction at the same time. The second pusher block 170 can push the frame 114 to descend in the vertical direction, thereby causing the carrier 110 to descend as a whole. This allows the pointed tip 134 to extend into the opening of the outer bag placed below the carrier 110. This allows the first guide plate 131 and the second guide plate 132 to open the opening of the outer bag when they are far apart and form an opening 133, thereby further ensuring that the inner bag 300 is accurately inserted into the outer bag.

[0066] Preferably, a second mounting member 161 is fixedly connected to the mounting bracket 160, and a second guide rod (not shown in the figure) is fixedly connected to the frame 114. The second mounting member 161 is sleeved on the outer periphery of the second guide rod, and a second spring 11451 is sleeved on the outer periphery of the second guide rod. The second spring 11451 abuts between the frame 114 and the second mounting member 161. Specifically, the second mounting member 161 includes a second mounting block 1611 and a second sleeve 1612. The second mounting block 1611 is fixedly connected to the mounting bracket 160, and the second sleeve 1612 is fixedly connected to the second mounting block 1611. The second sleeve 1612 is sleeved on the outer periphery of the second guide rod. When the second push block 170 pushes the frame 114 down in the vertical direction, the second spring 11451 undergoes elastic deformation, thereby having elastic potential energy to reset the frame 114 when the second push block 170 moves away from the frame 114.

[0067] Based on the foregoing, the material bagging device in this embodiment includes an inner bag bagging mechanism, which includes a carrier 110 and a first pusher 120. The first pusher 120 can push the inner bag 300 into the outer bag through the discharge port 1121, thereby pushing the material into the outer bag through the discharge port 1121. The carrier 110 has a first inlet 115 along the first horizontal direction. In addition to the inner bag bagging mechanism, the material bagging device in this embodiment also includes a hopper 210 and a material picking block 220. A stack of cards is placed in the hopper 210. The cards are used to record winning information and / or cartoon patterns and other information used to stimulate consumption. The bottom of the hopper 210 is provided with an opening 211. The material-taking block 220 has a suction nozzle 222 on its adsorption surface 221. The material-taking block 220 has a first working state where the adsorption surface 221 faces the opening 211, and a second working state where the adsorption surface 221 faces the pushing path of the first pusher block 120. In the first working state, the material-taking block 220 can extend into the opening 211 and pick up the card, and can also move the card out of the hopper 210 from the opening 211. When the material-taking block 220 is in the second working state, the material-taking block 220 passes through the first inlet 115 and extends into the receiving cavity 111, with the first end of the adsorption surface 221 facing the pushing path near the first pusher block 120. The card is tilted to the side, with the first end being the upstream end of the push path of the first push block 120 near the adsorption surface 221. This makes the push path of the first push block 120 form an angle with the card. In this embodiment, the outline of the adsorption surface 221 is smaller than the outline of the card. The part of the card located on the outer periphery of the first end is located on the push path of the first push block 120. The card can be clamped between the inner bag 300 and the first push block 120 that descends vertically. This allows the first push block 120 to push the card and the inner bag 300 simultaneously while pushing the inner bag 300 into the outer bag, thus pushing the card into the outer bag along with the inner bag 300.

[0068] Specifically, when the picking block 220 is in the first working state, the picking block 220 can pick up the card located at the bottom of the hopper 210 from the hopper 210 and remove the card from the hopper 210. When the picking block 220 is in the second working state, the picking block 220 sends the card into the receiving cavity 111 and tilts the card relative to the pushing path of the first push block 120, and the upper end of the card is located on the pushing path of the first push block 120.

[0069] Furthermore, based on the foregoing, when the inner bag 300 enters the receiving cavity 111 through the first inlet 115, the top sealing portion 310 of the inner bag 300 bends downwards due to the obstruction of the top plate 113. When the material picking block 220 feeds the card into the receiving cavity 111, the upper end of the card is wrapped between the top sealing portion 310 of the inner bag 300 and other parts of the inner bag 300. Subsequently, under the action of the push rod 140 and the pressure plate 121, the upper end of the card is further wrapped between the top sealing portion 310 of the inner bag 300 and other parts of the inner bag 300. Since the pressure plate 121 is located at the bottom of the first push block 120 and on the side of the first push block 120 that is close to the first inlet 115 in the horizontal direction, under the limitation of the pressure plate 121 on the first push block 120, the upper end of the card can be clamped between the pressure plate 121 and the inner bag 300. That is, the first push block 120 clamps the card with the inner bag 300 through the cooperation of the pressure plate 121 and the inner bag 300, so that the first push block 120 can push the card and the inner bag 300 at the same time when pushing the inner bag 300 into the outer bag, and then push the card into the outer bag together with the inner bag 300.

[0070] It is worth noting that in this embodiment, when the first push block 120 and the pressure plate 121 descend in the vertical direction, the guide groove 122 can also avoid the material taking block 220, thereby preventing the material taking block 220 from colliding with the pressure plate 121 and the first push block 120.

[0071] Based on the above, in this embodiment, the material-picking block 220 simultaneously inserts a card into the outer bag while the inner bag 300 containing the material is being inserted into the outer bag. Moreover, the entire process does not require manual intervention, thereby improving efficiency and meeting the needs of automated packaging.

[0072] In this embodiment, the material taking block 220 preferably includes a first block 223 and a second block 224. An adsorption surface 221 is formed on the side of the first block 223 away from the second block 224. A return spring 225 is connected between the first block 223 and the second block 224. The return spring 225 is disposed near the first end. The first block 223 is rotatably connected to the second block 224 through a first rotating shaft 226. The end of the adsorption surface 221 away from the first end is the second end. The first rotating shaft 226 is disposed near the second end, and the axis of the first rotating shaft 226 extends along a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. The second block 224 can move along the first horizontal direction and can rotate around the axis of the second rotating shaft 227, thereby driving the first block 223 to move along the first horizontal direction and drive the first block 223 to rotate around the axis of the second rotating shaft 227. The axis of the second rotating shaft 227 is parallel to the axis of the first rotating shaft 226.

[0073] Based on the above, the second block 224 can drive the first block 223 to rotate around the axis of the second rotating shaft 227, thereby enabling the adsorption surface 221 to switch between the first working state and the second working state. When the adsorption surface 221 switches from the first working state to the second working state, the second block 224 can drive the first block 223 to move along the first horizontal direction toward the carrier 110, thereby allowing the material taking block 220 to pass through the first inlet 115 and extend into the receiving cavity 111. When the card is pushed into the outer bag, the second block 224 can drive the first block 223 to move along the first horizontal direction toward the side away from the carrier 110, so that the material taking block 220 exits from the receiving cavity 111. Afterwards, the second block 224 can rotate around the axis of the second rotating shaft 227, thereby enabling the adsorption surface 221 to switch from the second working state to the first working state, and thus enabling the material taking block 220 to pick up the card again.

[0074] When the picking block 220 extends into the opening 211 and picks up the card, the first block 223 rotates around the axis of the first rotating shaft 226, and the return spring 225 is compressed, so that the adsorption surface 221 is attached to the bottom of the card at the bottom of the hopper 210, thereby ensuring that the picking block 220 can firmly adsorb the card. Afterwards, when the picking block 220 moves the card out of the hopper 210, the return spring 225 is reset, so that the adsorption surface 221 returns to the tilted state.

[0075] Furthermore, the material feeding device also includes a base frame 230 and a first driving member 240. The material picking block 220 also includes a third block 228, which is slidably connected to the base frame 230 along a first horizontal direction. The first driving member 240 is configured to drive the third block 228 to slide along the first horizontal direction. A second block 224 is rotatably connected to the third block 228 via a second rotating shaft 227. A connecting rod 229 is sleeved on the second rotating shaft 227. A first roller 2291 is installed at the end of the connecting rod 229 away from the second rotating shaft 227. The first roller 2291 is located on the side of the second rotating shaft 227 away from the first block 223. The axis of 2291 is parallel to the axis of the second rotating shaft 227. A slide groove 231 is provided on the base frame 230. The slide groove 231 includes a first groove 2311 and a second groove 2312. The first groove 2311 extends along a first horizontal direction. The second groove 2312 is located at the end of the first groove 2311 away from the carrier 110 along the first horizontal direction and extends downward in the vertical direction. The first roller 2291 is installed in the slide groove 231 and can roll along the extension direction of the slide groove 231. During the process of the first driving member 240 driving the third block 228 to move along the first horizontal direction, the first roller 2291 rolls in the slide groove 231.

[0076] Specifically, after the card is pushed into the outer bag, the third block 228 moves along the first horizontal direction toward the side away from the carrier 110. The first roller 2291 first rolls in the first groove 2311. At this time, the second block 224 and the first block 223 move together along the first horizontal direction toward the side away from the carrier 110. Then, the first roller 2291 moves into the second groove 2312. The third block 228 continues to move along the first horizontal direction toward the side away from the carrier 110. The first roller 2291 rolls along the second groove 2312. At this time, the second block 224 rotates around the axis of the second rotating shaft 227 and drives the first block 223 to rotate around the axis of the second rotating shaft 227, thereby switching the adsorption surface 221 from the second working state to the first working state.

[0077] After the material picking block 220 picks up the card again and removes the card from the hopper 210, the third block 228 moves along the first horizontal direction toward the side closer to the carrier 110. The first roller 2291 first rolls in the second groove 2312. At this time, the second block 224 rotates around the axis of the second rotating shaft 227, and drives the first block 223 to rotate around the axis of the second rotating shaft 227, thereby switching the adsorption surface 221 from the first working state to the second working state. After that, the first roller 2291 moves into the first groove 2311, and the third block 228 continues to move along the first horizontal direction toward the side closer to the carrier 110, while the first roller 2291 rolls along the first groove 2311.

[0078] It is understood that the first driving component 240 can be selected as a linear drive structure such as a cylinder, an electric cylinder, or an electric push rod, and no specific restrictions are made on this in this embodiment.

[0079] In order to facilitate the smooth transition of the first roller 2291 between the first groove 2311 and the second groove 2312, thereby avoiding affecting the movement of the material picking block 220, in this embodiment, the connection between the first groove 2311 and the second groove 2312 is an arc transition.

[0080] Furthermore, the material bagging device also includes a second drive member 250, which is configured to raise and lower the base frame 230 in the vertical direction, thereby raising the base frame 230 when the adsorption surface 221 is in the first working state, so that the picking block 220 extends into the opening 211 and picks up the card, and then lowers the base frame 230, so that the picking block 220 drives the card to move out of the hopper 210 from the opening 211.

[0081] It is understood that the second driving component 250 can be selected as a linear drive structure such as a cylinder, an electric cylinder, or an electric push rod, and no specific restrictions are made on this in this embodiment.

[0082] Based on the above, the bottom of the hopper 210 is provided with a second roller 212 and a third roller 213. The second roller 212 and the third roller 213 are both located inside the opening 211 and are arranged opposite each other. A stack of cards is placed on the second roller 212 and the third roller 213, so that while carrying a stack of cards, it is convenient for the material picking block 220 to pull the bottom card out of the hopper 210 through the opening 211. Specifically, when the material picking block 220 pulls the bottom card downward, the second roller 212 and the third roller 213 rotate, so that the card can be easily removed from the hopper 210 through the opening 211.

[0083] In addition, the bottom of the hopper 210 is provided with a first carrier block 214 and a second carrier block 215. The first carrier block 214 and the second carrier block 215 are both located in the opening 211 and are arranged opposite each other. A stack of cards is placed on the first carrier block 214 and the second carrier block 215 to ensure that the cards can be stably placed in the hopper 210. Preferably, the side of the first carrier block 214 facing the second carrier block 215 is beveled, and the side of the second carrier block 215 facing the first carrier block 214 is beveled to avoid affecting the material picking block 220 to move the bottommost card out of the hopper 210 through the opening 211.

[0084] Furthermore, the material bagging device also includes a pressing block 260, which can press against the topmost card in a stack of cards, thereby ensuring that the cards stacked in the hopper 210 remain flat. In addition, after the material taking block 220 takes away a card, the pressing block 260 can descend once, and the distance that the pressing block 260 descends each time is equal to the thickness of a card, thereby keeping the topmost card in the stack pressed against the material.

[0085] Based on the above, when the number of cards remaining in the hopper 210 is small, the pressing block 260 presses against the top card, that is, the pressing block 260 can limit the remaining cards, so the picking block 220 can still steadily pick up the bottom card.

[0086] It is worth noting that, based on the above, the carrier 110 is provided with two or more receiving cavities 111. Correspondingly, the material bagging device includes two or more hoppers 210 and two or more material picking blocks 220. The two or more material picking blocks 220 are arranged one-to-one with the two or more hoppers 210 and the two or more receiving cavities 111, so that cards are simultaneously fed into the two or more receiving cavities 111.

[0087] Based on the above description, the guide module 130 is used to guide the inner bag 300 during the process of pushing the inner bag 300 into the outer bag. In this embodiment, in addition to the first guide plate 131 and the second guide plate 132, the guide module 130 also includes a first rod 135 and a second rod 136. The first rod 135 and the second rod 136 are arranged opposite each other along a first horizontal direction. The first rod 135 includes a first rod portion 1351 and a second rod portion 1352. The second rod portion 1352 is located at one end of the first rod portion 1351 along a second horizontal direction perpendicular to the first horizontal direction and extends along the second horizontal direction. The second rod 136 includes a third rod portion 1361 and a fourth rod portion 1362. The fourth rod portion 1362 is located at one end of the third rod portion 1361 along the second horizontal direction and extends along the second horizontal direction. The first rod portion 1351 and the third rod portion 1361 surround the discharge port 1. On the outer periphery of 121, the second rod portion 1352 and the fourth rod portion 1362 are rotatably connected to the carrier 110. The first guide plate 131 is fixedly connected to the first rod portion 1351, and the second guide plate 132 is fixedly connected to the third rod portion 1361. After the first push block 120 pushes the inner bag 300 so that the inner bag 300 passes through the discharge port 1121 and enters between the first guide plate 131 and the second guide plate 132, under the push of the inner bag 300, the first guide plate 131 drives the first rod 135 to rotate around the axis of the second rod portion 1352, while the second guide plate 132 drives the second rod 136 to rotate around the axis of the fourth rod portion 1362. This causes the end of the first guide plate 131 away from the carrier 110 and the end of the second guide plate 132 away from the carrier 110 to move away from each other and form an opening 133, and the inner bag 300 is covered by the first guide plate 131 and the second guide plate 132.

[0088] Additionally, a first connecting block 13521 is provided on one radial side of the second rod portion 1352, and a third spring 137 is connected to the first connecting block 13521. The third spring 137 extends vertically, and the end of the third spring 137 away from the first connecting block 13521 is fixedly connected to the carrier 110. A second connecting block 13621 is provided on one radial side of the fourth rod portion 1362, and a fourth spring 138 is connected to the second connecting block 13621. The fourth spring 138 extends vertically, and the end of the fourth spring 138 away from the second connecting block 13521 is fixedly connected to the carrier 110. One end of the connecting block 13621 is fixedly connected to the carrier 110. Specifically, in this embodiment, the end of the third spring 137 away from the first connecting block 13521 and the end of the fourth spring 138 away from the second connecting block 13621 are both fixedly connected to the first mounting block 11411. A limit block 118 is provided on the carrier 110. The inner bag 300 can push the first guide plate 131 to rotate from the first working position to the second working position around the axis of the second rod 1352, and push the second guide plate 132 to rotate from the first working position to the second working position around the axis of the fourth rod 1362. When the third working position is rotated to the fourth working position, and the first guide plate 131 is in the first working position and the second guide plate 132 is in the third working position, the ends of the first guide plate 131 and the second guide plate 132 that are away from the carrier 110 approach each other and form a tip 134. When the first guide plate 131 is in the second working position and the second guide plate 132 is in the fourth working position, the ends of the first guide plate 131 and the second guide plate 132 that are away from the carrier 110 move away from each other and form a tip 134. The opening 133 is formed. The third spring 137 can elastically deform when the first guide plate 131 rotates from the first working position to the second working position. The fourth spring 138 can elastically deform when the second guide plate 132 rotates from the third working position to the fourth working position. When the first guide plate 131 is in the second working position, the first connecting block 13521 abuts against the limiting block 118. When the second guide plate 132 is in the fourth working position, the second connecting block 13621 abuts against the limiting block 118, thereby limiting the size of the opening 133.

[0089] Based on the above, after the inner bag 300 is pushed into the outer bag, the first pusher 120 resets. At the same time, since the first guide plate 131 and the second guide plate 132 lose the external force, the third spring 137 and the fourth spring 138 reset, thereby driving the first guide plate 131 to reset from the second working position to the first working position, and the second guide plate 132 to reset from the fourth working position to the third working position. That is, the end of the first guide plate 131 away from the carrier 110 and the end of the second guide plate 132 away from the carrier 110 approach each other and form a tip 134.

[0090] In this embodiment, there is no need to set up a separate driving structure for driving the first guide plate 131 and the second guide plate 132 to open or close, and the structure is simple.

[0091] Of course, in other alternative embodiments, the first guide plate 131 and the second guide plate 132 can be actuated by setting a driving structure for driving the first guide plate 131 and the second guide plate 132 to open or close, thereby forming an opening 133 or a tip 134. This embodiment does not impose specific limitations on this.

[0092] Example 2

[0093] Compared to Embodiment 1, the difference in this embodiment is that the inner bag 300 is smaller in size than the outer bag. Therefore, the closing part 310 at the top of the inner bag 300 does not need to be bent. When the inner bag 300 is pushed into the outer bag, the closing part 310 at the top of the inner bag 300 will not fall between the sealing parts at the top of the outer bag.

[0094] In this embodiment, after the material taking block 220 passes through the first inlet 115 and extends into the receiving cavity 111, the portion of the card located on the outer periphery of the first end is located on the pushing path of the first push block 120. The first push block 120 can descend to press the portion of the card located on the outer periphery of the first end against the top of the inner bag 300, thereby clamping the card between the inner bag 300 and the first push block 120 descending in the vertical direction. Thus, the first push block 120 can simultaneously push the card and the inner bag 300 while pushing the inner bag 300 into the outer bag, thereby pushing the card into the outer bag together with the inner bag 300.

[0095] Understandably, the other parts of the card can be held between the pressure plate 121 and the inner bag 300, thereby further ensuring that the card can be pushed into the outer bag along with the inner bag 300.

[0096] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
