[0002] With the development of logistics, the requirements for product packaging are constantly increasing. For products such as tissue boxes, beverages, and sanitary napkins, before leaving the factory, a high-strength plastic film needs to be wrapped around the stacked multiple small packages (4, 6, 8, 12, 16, or 24 packs) of tissue boxes or sanitary napkins to prevent dust, water, and loosening, so as to facilitate product transportation and shelf display.

[0003] Currently, the sheet material is first folded in half, then heated on both sides to form a tubular bag. Next, multiple stacked products are moved into the tubular bag. Finally, the tubular bag is heat-cut to complete the packaging. Many steps in the entire packaging process require manual intervention.

[0019] The following is in conjunction with the appendix Figure 1-18 This application will be described in further detail.

[0020] Reference Figure 1This application discloses a packaging device, including a storage mechanism 110, a covering device 120, a cutting mechanism 130, and a pushing mechanism 140. The storage mechanism 110 stores products. The covering device 120 is disposed on one side of the storage mechanism 110 and uses sheet material to form a tubular bag covering the product. The cutting mechanism 130 is disposed on the side of the covering device 120 away from the storage mechanism 110 and is used to cut the tubular bag to form a bag-shaped product. The pushing mechanism 140 is disposed on the common side of the storage mechanism 110, the covering device 120, and the cutting mechanism 130, and is used to transfer the product from the storage device to the covering device 120, and to transfer the tubular bag along with the product from the covering device 120 to the cutting mechanism 130 for cutting. Overall, it can replace or assist manual packaging of tissues or sanitary napkins, reducing reliance on manual labor and improving production cycle time.

[0021] Reference Figure 1 , Figure 2 and Figure 3In one embodiment, the storage mechanism 110 includes a first support 111, a second support 112, an interception grid 113, a first support 114, a first position adjustment component 115, a first height adjustment component 116, two first baffles 117, and two first spacing adjustment components 118. The first support 111 supports the interception grid 113 and the first position adjustment component 115. The second support 112 is mounted above the first support 111 and supports the first support 114, the first height adjustment component 116, and the first spacing adjustment component 118. The interception grid 113 is vertically oriented and used to intercept products. The interception grid 113 is slidably mounted on the first support 111 laterally. The first support 114 is horizontally oriented, with its top surface used to support products. Guide holes for the interception grid 113 to pass through are formed on the first support 114. Each guide hole extends laterally. The first support 114 is slidably mounted on the second support 112. The first position adjustment component 115 is mounted on the first bracket 111 and connected to the intercepting grid 113. It drives the intercepting grid 113 to move laterally, allowing more rows of products to be accommodated above the top of the first support 114 to meet different packaging needs and enhance the versatility of the storage mechanism 110. The first height adjustment component 116 is mounted on the second bracket 112 and connected to the first support 114. It drives the first support 114 to move vertically, allowing more layers of products to be stacked on the first support 114 to meet different packaging needs and enhance the versatility of the storage mechanism 110. Two first baffles 117 are slidably mounted on the top of the first support 114, facing each other or back to back. Two first spacing adjustment components 118 are respectively mounted on opposite sides of the first support 114. One first spacing adjustment component 118 is connected to one of the first baffles 117, and the other first spacing adjustment component is connected to the other first baffle 117. The two first spacing adjustment components 118 are used to drive the corresponding first baffles 117 to move, so as to adjust the regularity of the products after palletizing. The two first spacing adjustment components 118 are independent of each other, so that the movement of the two first baffles 117 is independent of each other, ensuring the flexibility of the position adjustment of each first baffle 117.

[0022] The working principle of the storage mechanism 110 is as follows: First, the first position adjustment component 115 drives the intercepting grid 113 to move laterally, reserving space above the top of the first support seat 114 to accommodate multiple rows of products. The feeding mechanism 150 continuously feeds rows of products onto the first support seat 114, while the intercepting grid 113 intercepts them. Then, the first height adjustment component 116 drives the first support seat 114 downwards, and the feeding mechanism 150 continuously feeds rows of products above the next layer of products. Simultaneously, the intercepting grid 113 intercepts the products. Next, the two first spacing adjustment components 118 respectively drive the corresponding first baffles 117 to move, using the two first baffles 117 to clamp multiple rows and layers of products, adjusting the regularity of the stacked products for easier packaging. Next, with the position of the intercepting grid 113 remaining unchanged, the first height adjustment component 116 drives the first support 114 to move upward, thereby moving the two first baffles 117, the first spacing adjustment component 118, and the multi-row multi-layer products upward. When the top surface of the first support 114 is higher than the top surface of the intercepting grid 113, the multi-row multi-layer products can be transferred to the covering device 120.

[0023] Preferably, the first position adjustment assembly 115 includes a first drive motor 1151, a first drive wheel 1152, a first driven wheel 1153, a first transmission belt 1154, and a first follower block 1155. The first drive motor 1151 is mounted on one end of the first bracket 111. The first drive wheel 1152 is sleeved on the output shaft of the first drive motor 1151. The first driven wheel is rotatably mounted on the other end of the first bracket 111. The first transmission belt 1154 is wound around the first drive wheel 1152 and the first driven wheel. The first follower block 1155 is fixed to the first transmission belt 1154 and is fixedly connected to the bottom end of the intercepting gate 113. The first drive motor 1151 drives the first drive wheel 1152 to rotate, thereby driving the first transmission belt 1154 to rotate, which in turn drives the first follower block 1155 and the intercepting gate 113 to move laterally, ensuring the efficiency of the position adjustment of the intercepting gate 113.

[0024] Preferably, the first height adjustment assembly 116 includes a second drive motor 1161, a first reduction gearbox 1162, a first transmission rod 1163, two second drive pulleys 1164, two second driven pulleys 1165, two second transmission belts 1166, and two second follower blocks 1167. The input shaft of the first reduction gearbox 1162 is fixedly connected to the output shaft of the second drive motor 1161, and the output shaft is fixedly connected to the first transmission rod 1163. The two second drive pulleys 1164 are respectively sleeved on opposite ends of the first transmission rod 1163. The two second driven pulleys 1165 are rotatably mounted on opposite sides of the second bracket 112. One second transmission belt 1166 is wound around one of the second drive pulleys 1164 and one of the second driven pulleys 1165, and the other second transmission belt 1166 is wound around the other second drive pulley 1164 and the other second driven pulley 1165. Two second follower blocks 1167 are fixedly attached to two second transmission belts 1166 in a one-to-one correspondence. The two second follower blocks 1167 are fixedly connected to opposite sides of the first support seat 114. The second drive motor 1161 drives the first transmission rod 1163 to rotate via the first reduction gearbox 1162, thereby rotating the two second drive wheels 1164, which in turn drives the two second transmission belts 1166 to rotate. This, in turn, causes the two second follower blocks 1167 and the first support seat 114 to move up and down, ensuring the efficiency of height adjustment of the first support seat 114.

[0025] Preferably, each first pitch adjustment assembly 118 includes a first lead screw 1181, a first nut 1182, a first follower seat 1183, a first operating wheel 1184, and a first electric push rod 1185. The first lead screw 1181 is rotatably mounted on the bottom end of the first support seat 114. The first nut 1182 is sleeved on the first lead screw 1181. The first follower seat 1183 is longitudinally movable and mounted on the first support seat 114, and is fixedly connected to the first nut 1182. The first operating wheel 1184 is fixed to one end of the first lead screw 1181 to drive the first lead screw 1181 to rotate. The first electric push rod 1185 is fixed to the top end of the first follower seat 1183, and its output shaft is fixedly connected to the outer wall of the first baffle 117. Before production, the user's hand drives the first operating wheel 1184 to rotate, which in turn drives the first lead screw 1181 to rotate. This, in turn, drives the first lead nut 1182, the first follower seat 1183, the first electric push rod 1185, and the first baffle 117 to move longitudinally for coarse adjustment of the position of the first baffle 117. During production, the first electric push rod 1185 is used to drive the first baffle 117 to move longitudinally for fine adjustment of the position of the first baffle 117. In this way, the efficiency and accuracy of the position adjustment of each first baffle 117 are ensured.

[0026] It should be noted beforehand that the sheet material is first folded in half, so that the opposite two sides of the sheet overlap, forming a fold line in the middle of the sheet material, which extends along the extension direction of the sheet material. Then, the folded sheet material is wound onto the storage roller 1223 of the sheet material feeding mechanism 122 to facilitate subsequent processes. Therefore, the sheet material released from the storage roller 1223 of the sheet material feeding mechanism 122 should have a double-layer structure.

[0027] Reference Figure 1 and Figure 4 In one embodiment, the covering device 120 includes a forming mechanism 121, a sheet feeding mechanism 122, and a heat sealing mechanism 123. The forming mechanism 121 adjusts the sheet after folding the opposite sides into a cylindrical shape and overlaps the two sides of the sheet after folding. The sheet feeding mechanism 122 is located below the forming mechanism 121 and feeds the folded sheet to the forming mechanism 121. The heat sealing mechanism 123 is located above the forming mechanism 121 and heats the overlapping sides of the sheet, connecting the two sides to form a cylindrical bag covering the product. Compared to existing covering devices, the process of forming the sheet into a cylindrical bag is smoother, avoiding excessive tension or looseness of the sheet during the forming process, thus preventing damage during the formation of the cylindrical bag. This results in a more regular appearance of the formed cylindrical bag, ensuring production efficiency and reducing waste of packaging materials.

[0028] Reference Figure 1 , Figure 4 and Figure 5 In one embodiment, the forming mechanism 121 includes a third support 1211, a forming cylinder 1212, a second spacing adjustment component 1213, and two support components 1214. The third support 1211 supports the forming cylinder 1212, the second spacing adjustment component 1213, and the two support components 1214. The forming cylinder 1212 is mounted on the top of the third support 1211, with an inlet at one end for attaching and folding sheet material, and an outlet at the other end for outputting a tubular bag; its interior is a guide cavity. The sheet material, after being folded at both sides, is folded into a tubular bag through the inlet, making the process of forming the sheet material into a tubular shape smoother, preventing breakage of the sheet material during forming, resulting in a more regular tubular shape, ensuring production efficiency, and reducing waste of packaging materials. The second spacing adjustment component 1213 is mounted on the third bracket 1211 and connected to the opposite sides of the forming cylinder 1212. It is used to adjust the spacing between the opposite sides of the forming cylinder 1212, thereby facilitating the formation of tubular bags of different widths to meet diverse packaging needs and enhancing the versatility of the forming mechanism 121. Two support components 1214 are mounted on the opposite sides of the second spacing adjustment component 1213 and connected to the corresponding sides of the forming cylinder 1212, providing enhanced support and reducing the possibility of sagging at the inlet.

[0029] Preferably, such as Figure 5 and Figure 6 As shown, the forming cylinder 1212 includes a base plate 12121, a first side plate 12122, a second side plate 12123, and a top plate 12124. The base plate 12121 has a first base plate segment 121211, a second base plate segment 121212, and a third base plate segment 121213 arranged longitudinally. The bottom surface of the second base plate segment 121212 near the discharge port is fixedly connected to the top of the third support 1211 and cannot move relative to the third support 1211. The bottom surface of the first base plate segment 121211 near the discharge port is slidably connected to the top of the third support 1211 via a slider and a slide rail. The bottom surface of the third base plate segment 121213 near the discharge port is slidably connected to the top of the third support 1211 via a slider and a slide rail. The bottom end of the first side plate 12122 is fixedly connected to the side of the first base plate segment 121211 away from the second base plate segment 121212. The bottom end of the second side plate 12123 is fixedly connected to the side of the third bottom plate segment 121213 away from the second bottom plate segment 121212. The top plate 12124 is longitudinally provided with a first top plate segment 121241 and a second top plate segment 121242. The side of the first top plate segment 121241 away from the second top plate segment 121242 is fixedly connected to the top end of the first side plate 12122. The side of the second top plate segment 121242 away from the first top plate segment 121241 is fixedly connected to the top end of the second side plate 12123. A first folding rod 1212411 is formed at the end of the first top plate segment 121241 near the feed inlet, through which one side of the sheet material is passed. A second folding rod 1212421 is formed at the end of the second top plate segment 121242 near the feed inlet, through which the other side of the sheet material is passed. The second folding rod 1212421 intersects with the first folding rod 1212411 and is positioned vertically.

[0030] The working principle of forming cylinder 1212 is as follows: Figure 10The direction of the middle arrow indicates the sheet movement direction. One side of the sheet from the sheet feeding mechanism 122 moves along the outer wall of the first side plate 12122 and the top surface of the first top plate section 121241 towards the first folding rod 1212411, and after passing the first folding rod 1212411, moves along the guide cavity towards the discharge port. The other side of the sheet moves along the outer wall of the second side plate 12123 and the top surface of the second top plate section 121242 towards the second folding rod 1212421, and after passing the second folding rod 1212421, moves along the guide cavity towards the discharge port. The two sides overlap after folding, which is beneficial for subsequent heat sealing. Simultaneously, the middle portion of the sheet is folded at the ends of the first side plate 12122 near the inlet, the second side plate 12123 near the inlet, the first bottom plate segment 121211 near the inlet, the second bottom plate segment 121212 near the inlet, and the third bottom plate segment 121213 near the inlet, and moves along the guide cavity towards the outlet. This forms the folded sheet into a cylindrical shape. It should be noted that a first adjustment gap is provided between the adjacent sides of the first bottom plate segment 121211 and the second bottom plate segment 121212. A second adjustment gap is provided between the third bottom plate segment 121213 and the second bottom plate segment 121212. On the one hand, the adjustable gap allows for easy adjustment of the distance between the inner walls of the first side plate 12122 and the second side plate 12123 at any time; on the other hand, the adjustable gap serves as a tolerance gap during forming, preventing the sheet from being too tight or too loose, thus avoiding damage to the sheet and ensuring the forming effect.

[0031] Preferably, the second pitch adjustment assembly 1213 includes two second follower seats 12131, two second lead screws 12132, two second lead screw nuts 12133, a first coupling (not shown in the figure), and a second operating wheel 12134. The two second follower seats 12131 are slidably mounted on the top of the third bracket 1211, facing each other or back to back. One of the second follower seats 12131 is fixedly connected to the outer wall of the first side plate 12122. The other second follower seat 12131 is fixedly connected to the outer wall of the second side plate 12123. The axes of the two second lead screws 12132 are aligned on the same straight line and are rotatably mounted on the top of the third bracket 1211. The two second lead screw nuts 12133 are sleeved on the second lead screws 12132 in a one-to-one correspondence. The two second lead screw nuts 12133 are fixedly connected to the two second follower seats 12131 in a one-to-one correspondence. The two opposite ends of the first coupling are fixedly connected to the adjacent ends of the two second lead screws 12132, respectively, to connect the two second lead screws 12132 and enable them to rotate synchronously. A second operating wheel 12134 is mounted on one end of one of the second lead screws 12132 for easy operation by the user's hand. The user's hand can drive the second operating wheel 12134 to rotate, thereby causing the two second lead screws 12132 to rotate synchronously, which in turn causes the two second lead screw nuts 12133 and the two second follower seats 12131 to move towards or away from each other, thus adjusting the distance between the inner walls of the first side plate 12122 and the second side plate 12123. Overall, this improves the efficiency and accuracy of distance adjustment.

[0032] Preferably, each support assembly 1214 includes a third follower seat 12141, a support plate 12142, a fourth follower seat 12143, a third lead screw 12144, a third lead screw nut 12145, and a third operating wheel 12146. The third follower seat 12141 is mounted on the corresponding side of the second follower seat 12131 and moves with the second follower seat 12131. The support plate 12142 is obliquely mounted on the top of the third follower seat 12141. The bottom end of the fourth follower seat 12143 is slidably connected to the top surface of the support plate 12142 via a slider and a slide rail. The fourth follower seat 12143 of one support assembly 1214 is fixedly connected to the outer wall of the first side plate 12122. The fourth follower seat 12143 of the other support assembly 1214 is fixedly connected to the outer wall of the second side plate 12123. The third lead screw 12144 is rotatably mounted on the top surface of the support plate 12142. The third lead nut 12145 is sleeved on the third lead screw 12144 and fixedly connected to the fourth follower seat 12143. The third operating wheel 12146 is mounted on one end of the third lead screw 12144. A human hand can drive the third operating wheel 12146 to rotate, thereby driving the third lead screw 12144 to rotate, which in turn drives the third lead nut 12145 and the fourth follower seat 12143 to move obliquely. In this way, the position of the fourth follower seat 12143 can be adjusted as needed, making the fourth follower seat 12143 suitable for supporting forming cylinders 1212 of different lengths and heights.

[0033] Reference Figure 4 , Figure 7 and Figure 8In one embodiment, the sheet feeding mechanism 122 includes a fourth support 1221, two clamping seats 1222, a storage roller 1223, an unwinding assembly 1224, a third spacing adjustment assembly 1225, two second height adjustment assemblies 1226, a fifth support 1227, two flattening rollers 1228, and a directional roller 1229. The fourth support 1221 is disposed on the common side of the second support 112 and the third support 1211, and supports the two clamping seats 1222, the storage roller 1223, the unwinding assembly 1224, the third spacing adjustment assembly 1225, and the two second height adjustment assemblies 1226. The two clamping seats 1222 are rotatably mounted on the fourth support 1221 and are used to clamp the storage roller 1223. One of the clamping seats 1222 can move toward or away from the other clamping seat 1222 to adjust the clamping force and adapt to storage rollers 1223 of different lengths, ensuring clamping effect and improving the versatility of the sheet feeding mechanism 122. Each clamping seat 1222 can move up and down. The storage roller 1223 is clamped between the two clamping seats 1222 and is used to store the rolled material after the opposite sides are folded, moving up and down with the two clamping seats 1222. The unwinding assembly 1224 is rotatably mounted on the fourth bracket 1221 and located below the storage roller 1223, used to release the sheet wound on the storage roller 1223, ensuring sheet release efficiency. The third spacing adjustment assembly 1225 is mounted on the fourth bracket 1221 and connected to one of the clamping seats 1222, used to drive the corresponding clamping seat 1222 to move toward or away from the other clamping seat 1222, ensuring the efficiency of spacing adjustment between the two clamping seats 1222. One of the second height adjustment components 1226 is mounted on the third spacing adjustment component 1225 and connected to one of the clamping seats 1222. The other second height adjustment component 1226 is mounted on the fourth bracket 1221 and connected to the other clamping seat 1222. The two second height adjustment components 1226 are used to drive the corresponding clamping seats 1222 to move up and down, ensuring the efficiency of the up and down movement of the clamping seats 1222. A fifth bracket 1227 is located below the third bracket 1211. Two flattening rollers 1228 are arranged side-by-side and rotatably mounted on the fifth bracket 1227, forming a sheet material channel between their sidewalls for flattening the rolled material after folding at opposite edges. The axis of the directional roller 1229 is parallel to the axis of the flattening roller 1228, fixed on the fifth support 1227, and located above the two flattening rollers 1228. This causes the opposite sides of the sheet to move towards the opposite outer sides of the forming cylinder 1212, and the middle of the sheet to move towards the feed inlet of the forming cylinder 1212. The cooperation between the two flattening rollers 1228 and the directional roller 1229 is more conducive to forming, ensuring forming effect and forming efficiency.

[0034] The sheet feeding mechanism 122 works as follows: The third spacing adjustment component 1225 drives the corresponding clamping seat 1222 to move toward or away from another clamping seat 1222 to clamp the storage roller 1223. The unwinding component 1224 contacts the outer side of the sheet on the storage roller 1223, and the rotating unwinding component 1224 gradually releases the sheet on the storage roller 1223. As the sheet on the storage roller 1223 decreases, the two second height adjustment components 1226 drive the two clamping seats 1222 to gradually move downwards, so that the unwinding component 1224 always maintains good contact with the outer side of the sheet, thereby ensuring the efficiency of the roll release. The roll released from the storage roller 1223 moves toward the feed port of the forming cylinder 1212 after passing through the sheet channel and the directional roller 1229.

[0035] Preferably, the unwinding assembly 1224 includes a third drive motor 12241, a drive roller 12242, a driven roller 12243, a drive sprocket 12244, a driven sprocket 12245, and a transmission chain 12246. The third drive motor 12241 is mounted on a fourth bracket 1221. One end of the drive roller 12242 is fixedly connected to the output shaft of the third drive motor 12241, and its sidewall can contact the outer side of the sheet. The driven roller 12243 is arranged side-by-side with the drive roller 12242 and is rotatably mounted on the fourth bracket 1221, with its sidewall also capable of contacting the outer side of the sheet. The drive sprocket 12244 is sleeved on the end of the drive roller 12242 away from the third drive motor 12241. The driven sprocket 12245 is sleeved on the end of the driven roller 12243 away from the third drive motor 12241. The drive chain 12246 is wound around the drive sprocket 12244 and the driven sprocket 12245. The third drive motor 12241 drives the drive roller 12242 to rotate, which in turn drives the driven roller 12243 to rotate via the drive sprocket 12244, drive chain 12246, and driven sprocket 12245, thereby gradually releasing the sheet material on the storage roller 1223. This ensures the smoothness and efficiency of the sheet material release.

The fourth operating wheel 12254 is fixedly connected to one end of the first gear 12253. The human hand drives the fourth operating wheel 12254 to rotate, thereby driving the first gear 12253 to rotate, which in turn drives the fifth follower seat 12252, the corresponding second height adjustment assembly 1226, and the corresponding clamping seat 1222 to move longitudinally, ensuring the efficiency and accuracy of the spacing adjustment of the two clamping seats 1222.

[0037] Preferably, each second height adjustment component 1226 is a rodless cylinder with a transmission block 12261. The transmission block 12261 is rotatably connected to the corresponding clamping seat 1222 to drive the corresponding clamping seat 1222 to move up and down.

[0038] Reference Figure 4 and Figure 9 In one embodiment, the heat-sealing mechanism 123 includes a sixth support 1231, a hot air welder 1232, a support plate 1233, and a third height adjustment assembly 1234. The sixth support 1231 is positioned above the third support 1211 and supports the hot air welder 1232, the support plate 1233, and the third height adjustment assembly 1234. The hot air welder 1232 is movably mounted on the sixth support 1231, blowing hot air onto both sides of the sheet to heat the sides and connect them. This non-contact heating method achieves continuous heat sealing, ensuring production cycle time. The support plate 1233 is positioned below the hot air welder 1232 and within the guide cavity. Its top surface supports the folded sides of the sheet and is movably mounted on the sixth support 1231. During the heat sealing process, the support plate 1233 supports both sides of the sheet material, ensuring the heat sealing effect. The third height adjustment component 1234 is installed on the sixth bracket 1231 and is connected to the hot air welder 1232 and the support plate 1233 respectively. It is used to drive the hot air welder 1232 and the support plate 1233 to move up and down, so as to adjust the height of the hot air welder 1232 and the support plate 1233 in the vertical direction, which helps to ensure the heat sealing effect and heat sealing efficiency.

[0039] Preferably, the third height adjustment assembly 1234 includes a sixth follower seat 12341, a fourth lead screw 12342, a fourth lead screw nut 12343, and a fifth operating wheel 12344. The sixth follower seat 12341 is movably mounted on the sixth bracket 1231, and a hot air welder 1232 is fixed to its bottom end. The axis of the fourth lead screw 12342 is vertically arranged and rotatably mounted on the sixth bracket 1231. The fourth lead screw nut 12343 is sleeved on the fourth lead screw 12342 and fixedly connected to the sixth follower seat 12341. The fifth operating wheel 12344 is fixedly connected to the bottom end of the fourth lead screw 12342. The human hand can drive the fifth operating wheel 12344 to rotate, thereby driving the fourth lead screw 12342 to rotate, which in turn drives the fourth lead screw nut 12343 and the sixth follower seat 12341 to move up and down, thus driving the hot air welder 1232 and the support plate 1233 to move up and down, ensuring the efficiency and accuracy of the position adjustment of the hot air welder 1232 and the support plate 1233. The end of the support plate 1233 near the feed port of the forming cylinder 1212 is bent upward to form a limiting part 12331. The limiting part 12331 is fixedly connected to one end of the sixth follower seat 12341. When the sheet passes around the first folding rod 1212411 / second folding rod 1212421, the limiting part 12331 plays a limiting role, allowing the sheet to pass around the first folding rod 1212411 / second folding rod 1212421 more smoothly.

[0040] Preferably, such as Figure 9 As shown, the heat sealing mechanism 123 also includes a second electric push rod 1235, a seventh follower seat 1236, a pressure roller 1237, and a magnet 1238. The second electric push rod 1235 is mounted on the bottom of the sixth follower seat 12341 at the end away from the limiting part 12331, with its output shaft facing downwards. The seventh follower seat 1236 is fixedly connected to the output shaft of the second electric push rod 1235. The pressure roller 1237 is rotatably mounted on the bottom of the seventh follower seat 1236, and its sidewall can press against the top surface of the support plate 1233. The magnet 1238 is mounted on the seventh follower seat 1236 and moves up and down with the seventh follower seat 1236 to attract the end of the support plate 1233 away from the feed port of the forming cylinder 1212. The second electric push rod 1235 can drive the seventh follower seat 1236 to move up and down, thereby driving the pressure roller 1237 and the magnet 1238 to move up and down. The pressure roller 1237 reduces the friction between the sheet and the bottom of the seventh follower seat 1236, preventing damage to the sheet and ensuring the sheet's moving efficiency. The magnet 1238 attracts the end of the support plate 1233 away from the feed inlet, preventing excessive sag at that end and ensuring a good heat-sealing effect.

The resistance heating component 135 is mounted on the top of the second support seat 1321 and moves up and down with the second support seat 1321, used to heat the cylindrical bag. Two first pressure plates 136 are positioned opposite each other and installed at the bottom of the pressure base 1322. They move up and down with the pressure base 1322 to press the tubular bag against the top of the resistance heating component 135, ensuring a tight fit between the tubular bag and the resistance heating component 135 and guaranteeing the heating effect. Two second pressure plates 1371 are positioned between the two first pressure plates 136 and are movably installed at the bottom of the pressure base 1322. Before cutting the tubular bag, the bottom ends of the two second pressure plates 1371 press against the tubular bag, effectively preventing the bag from shifting during the cutting process and ensuring the cutting effect. A cutting blade 1372 is positioned between the two second pressure plates 1371 and is movably installed at the bottom of the pressure base 1322 to cut the heated tubular bag. The sixth height adjustment component 138 is mounted on the pressure base 1322 and connected to the two second pressure plates 1371.

The seventh height adjustment component 139 is mounted on the pressure base 1322 and connected to the cutting blade 1372. It is used to drive the cutting blade 1372 to move up and down, ensuring the efficiency and accuracy of the up and down movement of the cutting blade 1372.

[0042] The cutting mechanism 130 operates as follows: When the tubular bag moves to the cutting mechanism 130 along with the product, the fourth height adjustment component 133 drives the second support seat 1321 upward, thereby moving the resistance heating component 135 upward. Simultaneously, the fifth height adjustment component 134 drives the pressure seat 1322 downward, thereby moving the two first pressure plates 136, the two second pressure plates 1371, the cutting blade 1372, the sixth height adjustment component 138, and the seventh height adjustment component 139 downward. The two first pressure plates 136 ensure close contact between the tubular bag and the top of the resistance heating component 135, guaranteeing the heating effect. Then, the sixth height adjustment component 138 drives the two second pressure plates 1371 downward, causing their bottom ends to press against the tubular bag to prevent movement during the cutting process. Next, the seventh height adjustment component 139 drives the cutting blade 1372 downward to cut the tubular bag. Overall, it can cut the cylindrical bag covering the product into segments to form individual bag-shaped products.

The third pressure plate 163 is disposed between the two second baffles 162 and is movably mounted on the tenth support 161, forming a product channel with the two second baffles 162. When the product passes through the product channel, the third pressure plate 163 and the two second baffles 162 cooperate with each other, improving the regularity of the product after stacking, facilitating smooth packaging, and ensuring packaging effectiveness. The fourth spacing adjustment component 164 is mounted on the tenth bracket 161 and connected to the two second baffles 162. It is used to drive the two second baffles 162 to move towards or away from each other, ensuring the efficiency and accuracy of the movement of the second baffles 162. The eighth height adjustment component 165 is mounted on the fourth spacing adjustment component 164 and connected to the third pressure plate 163.

The axes of the two fifth lead screws 1642 are aligned on the same straight line and are rotatably mounted on the bottom of the tenth bracket 161. The two fifth lead screw nuts 1643 are sleeved on the fifth lead screws 1642 in a one-to-one correspondence. The two fifth lead screw nuts 1643 are fixedly connected to the two tenth follower seats 1641 in a one-to-one correspondence. The two opposite ends of the second coupling 1644 are fixedly connected to the adjacent ends of the two fifth lead screws 1642, respectively, to connect the two fifth lead screws 1642 and enable them to rotate synchronously. A sixth operating wheel 1645 is mounted on one end of one of the fifth lead screws 1642 for easy operation by the user's hand. The user's hand can drive the sixth operating wheel 1645 to rotate, thereby causing the two fifth lead screws 1642 to rotate synchronously, which in turn causes the two fifth lead screw nuts 1643 and the two tenth follower seats 1641 to move towards or away from each other, thus adjusting the distance between the two second baffles 162. Overall, this improves the efficiency and accuracy of distance adjustment.

[0057] Preferably, the third pressing plate 163 has two pressing sections 1631 arranged longitudinally. The eighth height adjustment assembly 165 includes four adjusting plates 1651.

[0058] Reference Figure 1 , Figure 17 and Figure 18In one embodiment, the discharging mechanism 170 includes an eleventh bracket 171, a twelfth bracket 172, two third baffles 173, a fourth pressure plate 174, two insert plates 175, two fifth spacing adjustment components 176, and a ninth height adjustment component 177. The eleventh bracket 171 supports the bag-shaped product. The twelfth bracket 172 is disposed above the eleventh bracket 171 and supports the two third baffles 173, the fourth pressure plate 174, the two insert plates 175, the two fifth spacing adjustment components 176, and the ninth height adjustment component 177. The two third baffles 173 are slidably mounted on the twelfth bracket 172 facing each other or back to back. The fourth pressure plate 174 is disposed between the two third baffles 173 and is movably mounted on the twelfth bracket 172, forming a product outlet with the two third baffles 173. Two insert plates 175 are slidably mounted on the twelfth bracket 172, facing each other or back to back, to form grooves on opposite sides of each end of the bag-shaped product. When the bag-shaped product passes through the product outlet, the fourth pressure plate 174 cooperates with the two third baffles 173 to improve the regularity of the bag-shaped product. Two fifth spacing adjustment components 176 are respectively mounted on the twelfth bracket 172. One fifth spacing adjustment component 176 is connected to one of the third baffles 173 and one insert plate 175. The other fifth spacing adjustment component 176 is connected to the other third baffle 173 and the other insert plate 175. The two fifth spacing adjustment components 176 are used to drive the corresponding third baffle 173 and the corresponding insert plate 175 to move, so as to ensure the moving efficiency and accuracy of the third baffle 173 and the insert plate 175, thereby ensuring the regularization efficiency and regularization effect. The two fifth spacing adjustment components 176 are independent of each other, so that the movements of the two third baffles 173 and the two inserts 175 are independent of each other, ensuring the flexibility of position adjustment for each third baffle 173 and each insert 175. The ninth height adjustment component 177 is mounted on the twelfth bracket 172 and connected to the fourth pressure plate 174. It is used to drive the fourth pressure plate 174 to move up and down, so as to ensure the efficiency and accuracy of the up and down movement of the fourth pressure plate 174, thereby ensuring the leveling efficiency and leveling effect.

[0059] The working principle of the discharge mechanism 170 is as follows: The first pusher plate 143 of the pushing mechanism 140 pushes the bag-shaped product laterally to the product outlet. Just before the bag-shaped product enters the product outlet, the two fifth spacing adjustment components 176 respectively drive the corresponding insert plates 175 to move, forming grooves on opposite sides of one end of the bag-shaped product. After the bag-shaped product enters the product outlet, the two fifth spacing adjustment components 176 respectively drive the corresponding insert plates 175 to move, forming grooves on opposite sides of the other end of the bag-shaped product. Simultaneously, the ninth height adjustment component 177 drives the fourth pressure plate 174 downwards, so that the fourth pressure plate 174 presses against the top of the bag-shaped product.

[0060] Preferably, each fifth pitch adjustment assembly 176 includes a second rack 1761, an eleventh follower seat 1762, a second gear 1763, a seventh operating wheel 1764, and a fifth electric push rod 1765. The second rack 1761 is fixed to the twelfth bracket 172. The eleventh follower seat 1762 is slidably mounted on the twelfth bracket 172 in the longitudinal direction and is fixedly connected to the outer wall of the third baffle 173. The second gear 1763 is rotatably mounted on the eleventh follower seat 1762, and its side wall is meshed with the second rack 1761. The seventh operating wheel 1764 is fixedly connected to one end of the second gear 1763. The fifth electric push rod 1765 is fixed to the eleventh follower seat 1762, and its output shaft is fixedly connected to the insert plate 175. Before production, the user's hand drives the seventh control wheel 1764 to rotate, which in turn drives the second gear 1763 to rotate. This, in turn, moves the eleventh follower seat 1762, the third baffle 173, the fifth electric push rod 1765, and the insert plate 175 longitudinally to coarsely adjust the positions of the two third baffles 173 and the two insert plates 175. During production, the fifth electric push rods 1765 of the two fifth spacing adjustment components 176 drive the corresponding insert plates 175, causing the two insert plates 175 to move towards each other to finely adjust their positions. This ensures the effective formation of the grooves on both sides.

[0061] Preferably, each ninth height adjustment assembly 177 includes a twelfth follower seat 1771, a sixth electric push rod 1772, a sixth lead screw 1773, a sixth lead screw nut 1774, and an eighth operating wheel 1775. The twelfth follower seat 1771 is slidably mounted on the twelfth bracket 172. The sixth electric push rod 1772 is fixed to one side of the twelfth follower seat 1771, with its output shaft facing downwards. The output shaft of the sixth electric push rod 1772 is fixedly connected to the top end of the fourth pressure plate 174. The axis of the sixth lead screw 1773 is vertically arranged and rotatably mounted on the twelfth bracket 172. The sixth lead screw nut 1774 is sleeved on the sixth lead screw 1773 and fixedly connected to the twelfth follower seat 1771. The eighth operating wheel 1775 is mounted on the bottom end of the sixth lead screw 1773. Before production begins, the operator's hand drives the eighth control wheel 1775 to rotate, which in turn rotates the sixth lead screw 1773. This, in turn, drives the sixth lead screw nut 1774, the twelfth follower seat 1771, the sixth electric push rod 1772, and the fourth pressure plate 174 to move up and down, thus coarsely adjusting the vertical height of the fourth pressure plate 174. During production, the sixth electric push rod 1772 drives the fourth pressure plate 174 downwards, thus finely adjusting its vertical height. This ensures both efficiency and accuracy in adjusting the position of the fourth pressure plate 174.

[0062] In one embodiment, the packaging equipment also includes a controller. The controller is electrically connected to each drive motor and each electric push rod, respectively, to control their operation, thereby increasing the level of automation.

[0063] The implementation principle of this embodiment is as follows: A covering device 120 is disposed on one side of the storage mechanism 110, using sheet material to form a tubular bag covering the product. A cutting mechanism 130 is disposed on the side of the covering device 120 away from the storage mechanism 110, used to cut the tubular bag to form a bag-shaped product. A feeding mechanism 150 is disposed on the common side of the storage mechanism 110 and the covering device 120, used to feed the product from the conveyor line onto the first support seat 114 of the storage mechanism 110 for stacking. A regularity adjustment mechanism 160 is disposed between the first support seat 114 of the storage mechanism 110 and the forming mechanism 121 of the covering device 120, used to regularize the stacked product. A discharge mechanism 170 is disposed on the side of the cutting mechanism 130 away from the forming mechanism 121, used to regularize the bag-shaped product. The pushing mechanism 140 transfers the palletized products from the first support seat 114 of the storage device to the regularity adjustment mechanism 160 for regularization. The regularized products are then transferred from the regularity adjustment mechanism 160 to the forming mechanism 121 of the covering device 120. The tubular bags are then transferred along with the products from the forming mechanism 121 to the cutting mechanism 130 for cutting. Finally, the bagged products are transferred to the discharging mechanism 170. Before packaging, the regularity adjustment mechanism 160 improves the regularity of the palletized products, which facilitates packaging and ensures a smooth production cycle. It also helps ensure the packaging effect. After packaging, the discharging mechanism 170 improves the regularity of the packaged products, ensuring the packaging appearance. Overall, this method can replace or assist manual packaging of tissues or sanitary napkins, reducing reliance on manual labor, increasing production cycle time, and ensuring packaging efficiency and effect.
