Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0029] <Example>

[0030] See Figure 1 This utility model provides a multi-channel bagging device, including a frame (not shown) and a bag hanging mechanism 1 and a bag opening mechanism 2 disposed on the frame.

[0031] The frame serves as the support structure for the multi-channel bagging device and is installed on the production line. Its shape and installation position on the production line can be customized according to production needs.

[0032] The bag hanging mechanism 1 includes: wall panel 15, bag suction unit 11, main rotation unit 13, fine-tuning rotation unit 14, and forward and backward movement unit 12.

[0033] Wall panel 15 is vertically mounted and fixed to the frame. See also Figure 2 and Figure 6 The wall panel 15 has two parallel strip-shaped through holes 15a.

[0034] See Figure 1 , Figure 2 and Figure 7 The suction bag unit 11 includes two identical suction bag units, one above the other. Each suction bag unit 11 includes a distribution pipe 111 and n sets of suction blocks 112 arranged on the distribution pipe 111, where n is greater than or equal to 2. Each set of suction blocks 112 consists of two suction blocks 112, and the distance between the two suction blocks 112 is less than the width of the packaging bag. The distribution pipe 111 is connected to a suction device (not shown in the figure) to create a negative pressure inside the pipe, thereby adsorbing the packaging bag. The suction device is a commercially available product and is not an improvement of this utility model, so it will not be described in detail here. The set of suction blocks 112 of the upper suction bag unit 11 and the set of suction blocks 112 of the lower suction bag unit 11 cooperate to respectively suction the upper and lower surfaces of the same packaging bag.

[0035] In this embodiment, each suction unit 11 has two sets of suction blocks 112 on its air distribution pipe 111. Therefore, the bag hanging mechanism 1 can operate on two packaging bags simultaneously. That is, the multi-way bagging device in this embodiment is a dual-way bagging device. However, this is not a limitation. In other embodiments, each suction unit can have more sets of suction blocks on its air distribution pipe, such as three sets. In this case, the multi-way bagging device is a three-way bagging device, which can operate on three packaging bags simultaneously.

[0036] See Figures 3 to 5 The main rotating unit 13 is used to drive the two suction bag units 11 to rotate closer or further away. The main rotating unit 13 includes: a first driving cylinder 132, a guide plate 133, a sliding wheel 134, an arm 135, a connecting shaft 137, a connecting shaft connecting arm 138, a hinge link assembly 136, a limiting strip 139, and a vertical guide rail slide assembly 130.

[0037] The coupling includes two couplings 137, one above the other, which are connected to the upper and lower suction bag units 11 via coupling connecting arms 138, respectively. See also Figure 6 One end of the connecting arm 138 is fixedly connected to the connecting shaft 137.

[0038] The first drive cylinder 132 is fixed to the wall panel 15 via the cylinder mounting base 131. The guide plate 133 is connected to the first drive cylinder 132 via a connecting block, and the guide plate 133 is moved up and down by the first drive cylinder 132.

[0039] Two sets of vertical guide rail slide assemblies 130 are of the same structure, located on opposite sides of the back of the guide plate 133. Each set of vertical guide rail slide assemblies 130 includes: a vertical guide rail 130a, a slide 130b, and a guide plate mounting plate 130c. The vertical guide rail 130a is vertically mounted and fixed to the wall panel 15. The slide 130b is slidably mounted to the vertical guide rail 130a. The guide plate mounting plate 130c is fixed to the slide 130b. The guide plate mounting plate 130c is fixed to the guide plate 133. When the guide plate 133 moves up and down, the slide 130b in the two sets of vertical guide rail slide assemblies 130 slides along the vertical guide rail 130a, providing a smoothing effect for the up and down movement of the guide plate 133.

[0040] The guide plate 133 has a zigzag-shaped guide groove 133a. The sliding wheel 134 is located in 133a. One end of the arm 135 is connected to the sliding wheel 134 by bolts, and the other end of the arm 135 is fixedly connected to the connecting shaft 137 below. When the guide plate 133 moves up and down, it will drive the sliding wheel 134 to slide in the guide groove 133a, causing the arm 135 to swing. The swinging of the arm 135 will drive the connecting shaft 137 below to rotate.

[0041] The hinge linkage assembly 136 consists of three links connected sequentially via hinges. The lower link 136a is fixedly connected to the lower shaft 137 and is driven to rotate by the lower shaft 137. The middle link 136c is connected to the lower link 136a via a pin 136b, and the upper link 136e is connected to the middle link 136c via a pin 136d. The upper link 136e is fixedly connected to the upper shaft 137. When the arm 135 rotates, causing the lower shaft 137 to rotate, the hinge linkage assembly 136 causes the upper link 136e to drive the upper shaft 137 to rotate synchronously in the opposite direction to the lower shaft 137.

[0042] Rotating the two connecting shafts 137 at the top and bottom will cause the two connecting arms 138 at the top and bottom to rotate closer or further apart, thus causing the two suction bag units 11 to rotate closer or further apart. For the case where the two suction bag units 11 rotate further apart, see [link to relevant documentation]. Figure 4 The curved arrow indicates that the bag opening will be opened.

[0043] Preferably, see Figure 4 The main rotating unit 13 is equipped with a limiting plate 139, which has multiple through holes. The upper and lower connecting shafts 137 pass through different through holes in the limiting plate 139. The limiting plate 139 serves a stabilizing function.

[0044] See Figures 1 to 4 as well as Figure 7The fine-tuning rotation unit 14 is used to fine-tune the suction bag unit 11. The fine-tuning rotation unit 14 includes an upper fine-tuning rotation unit 14a and a lower fine-tuning rotation unit 14b, and the structures of the upper and lower fine-tuning rotation units are different.

[0045] The lower fine-tuning rotation unit 14b includes a fixing block 141 with a hole for the connecting shaft 137 to pass through. A bracket 142 is fixed on the fixing block 141, and a second drive cylinder 147 is fixed on the bracket 142. The second drive cylinder 147 is connected to a fisheye connecting rod 143, which is connected to a fisheye connector 144. The fisheye connector 144 is connected to the connecting arm 145.

[0046] The upper fine-tuning rotation unit 14a includes a fixing block 141 with a hole for the connecting shaft 137 to pass through. A bracket 142 is fixed on the fixing block 141, and a fisheye connecting rod 143 is fixed on the bracket 142. The fisheye connecting rod 143 is connected to a fisheye connector 144, and the fisheye connector 144 is connected to the connecting arm 145.

[0047] The connecting arms 145 in the upper fine-tuning rotation unit 14a and the lower fine-tuning rotation unit 14b are respectively connected to the air distribution pipes 111 in the upper suction bag unit 11 and the lower suction bag unit 11. (See also...) Figure 6 A rotating bearing is provided at the connection point between the connecting arm 138 and the air distribution pipe 111 of the suction bag unit 11, allowing the air distribution pipe 111 to rotate within the bearing. The lower fine-tuning rotation unit 14b is an active component, which, through the operation of the second drive cylinder 147, enables the air distribution pipe 111 in the lower suction bag unit 11 to rotate. The upper fine-tuning rotation unit 14a is not adjusted during packaging production but can be manually adjusted during maintenance or pre-production adjustments.

[0048] See Figure 1 , Figure 2 and Figure 6 The forward and backward moving unit 12 is used to drive the two suction bag units 11 to move back and forth. The forward and backward moving unit 12 includes a drive motor 121, an active synchronous pulley 122, a driven synchronous pulley 124, a belt 123, a belt connecting plate 125, a vertical plate 126, a slide table 127, and a transverse guide rail 128.

[0049] The drive motor 121 is mounted and fixed to the wall panel 15 via a motor mounting bracket. The drive motor 121 drives the active synchronous pulley 122 to rotate. A belt 123 is connected to the active synchronous pulley 122, and the belt 123 is lateral, corresponding to the front-back direction of the bag-opening mechanism 1. The belt 123 is driven to rotate by the active synchronous pulley 122. The driven synchronous pulley 124 is mounted on the wall panel 15 via a pulley mounting bracket and is connected to the belt 123. The vertical plate 126 is fixed to the belt 123 via a belt connecting plate 125 and screws. It moves back and forth driven by the belt 123.

[0050] The upper and lower fixing blocks 141 are respectively fixed to the vertical plate 126. The vertical plate 126 has multiple through holes, and the upper and lower connecting shafts 137 pass through the through holes in the vertical plate 126.

[0051] The horizontal guide rail 128 is horizontally positioned and fixed to the wall panel 15. The sliding table 127 is slidably mounted on the horizontal guide rail 128 in cooperation with it. The vertical plate 126 is fixed to the sliding table 127, and in the vertical direction of the vertical plate, the sliding table 127 is positioned between the upper and lower fixed blocks 141. When the vertical plate 126 moves back and forth, the sliding table 127 slides along the horizontal guide rail 128, providing guidance and stability.

[0052] See Figure 1 , Figures 8 to 10 The bag opening mechanism 2 includes: a door plate 24, a mold cylinder 21, an air blowing unit 22 for opening the mold cylinder 21, and a cylinder pushing unit 23 for retracting the mold cylinder 21.

[0053] The number of molded cylinders 21 is the same as the number of groups of suction blocks 112, which is two groups in this embodiment, enabling simultaneous operation on two packaging bags. However, this is not a limitation. In other embodiments, the number of molded cylinders 21 can be set to more groups according to the number of groups of suction blocks 112, enabling simultaneous operation on more packaging bags.

[0054] The air-blowing unit 22 includes an air-blowing pipe 221 and an inflation device (not shown in the figure). The inflation device is a commercially available product and is not an improvement of this utility model; therefore, it will not be described in detail here. The molded cylinder 21 is mounted on the door plate 24. The door plate 24 has air holes at positions corresponding to the molded cylinder 21, and each air hole is connected to an air-blowing pipe 221, which is connected to the inflation device. Air is blown through the air-blowing pipe 221, causing the molded cylinder 21 to open, thereby fully opening the packaging bag located on the outer periphery of the molded cylinder.

[0055] The cylinder pushing unit 23 includes a cylinder mounting bracket 231, a cylinder 232, a push plate 233, a push rod 234, an L-shaped connecting block 237, a hinge seat 236, a round bottom block 235, and an auxiliary pressure block 238.

[0056] The door panel 24 and the cylinder mounting bracket 231 are fixed to a base (not shown in the figure). The base can be mounted on the frame via a lifting device, such as a commercially available product, like a hydraulic lifting device. Therefore, the entire bag-opening mechanism 2 can rise or fall relative to the bag-hanging mechanism 1.

[0057] Cylinder 232 is fixed to cylinder mounting bracket 231. Push plate 233 connects to cylinder 232, and push rod 234 is fixed to push plate 233. Door panel 24 has through holes at the positions corresponding to rod 234 for push rod 234 to pass through. Cylinder 232 is preferably a three-axis cylinder. Hinge seat 236 is fixed to door panel 24, and L-shaped connecting block 237 is hinged to hinge seat 236 at a right angle. One end of L-shaped connecting block 237 is provided with round bottom block 235, the position of which corresponds to the through hole on door panel 24. An auxiliary pressure block 238 is fixed to the other side surface of L-shaped connecting block 237.

[0058] See Figures 9 to 11 When the shaft of cylinder 232 extends, it will drive the push plate 233 to move, thereby driving the push rod 234 into the through hole of the door plate 24. The push rod 234 pushes up the round bottom block 235, thereby causing the L-shaped connecting block 237 to be in a certain position. Figure 11 As shown in the posture, the auxiliary pressure block 238 presses down on the side of the mold cylinder 21, causing the mold cylinder 21 to be in a contracted state.

[0059] The connection methods between other components not described in detail in this embodiment are conventional connection methods such as bolt connection, welding, plug connection, and socket connection, which are adopted according to the actual situation and will not be described in detail one by one.

[0060] The working process of the multi-channel bagging device in this embodiment of the utility model is as follows:

[0061] The bag hanging mechanism 1 works as follows: the bag suction unit 11 suctions the upper and lower surfaces of the packaging bag; then, the main rotation unit 13 and the fine-tuning rotation unit 14 move to open the opening of the packaging bag; then, the forward and backward moving unit 12 moves to send the packaging bag to the position of the mold cylinder 21.

[0062] The bag-opening mechanism 2 operates as follows: The cylinder-driven unit 23 initially keeps the forming cylinder in a contracted state. When the packaging bag is delivered to the forming cylinder 21, the cylinder-driven unit 23 retracts, and the air-blowing unit 22 blows air to open the forming cylinder 21, thus fully opening the bag and completing the bag-opening process. After bag opening, the bag-opening mechanism 2 is lowered via a lifting device, and then workers or other production equipment process the packaging bag for the next step.

[0063] The multi-channel bagging device in this embodiment is a dual-channel bagging device, which can simultaneously bag two packaging bags, doubling the efficiency. Other multi-channel bagging devices, such as a three-channel bagging device, can simultaneously bag three packaging bags. Further details on other multi-channel bagging devices are omitted here.

[0064] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
