Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically a bagging machine. Background Technology

[0002] Some disposable cups require lids, especially milk tea cups. Currently, after production, the lids are manually stacked and placed into cylindrical plastic bags. To improve packaging efficiency and reduce labor costs, mechanical packaging is also used. For example, patent CN220199723U discloses a horizontal stacking and bagging device for square cup lids. This device utilizes a push-lid mechanism and a rotary lid-collecting mechanism. The push-lid mechanism pushes the lids forward one by one, and the lid-moving mechanism pushes a stack of lids into a collecting cylinder. A third cylinder then contracts, causing the collecting cylinder to descend and all the lids to enter the bag. However, this device does not disclose how the bag is fed; that is, manual handling is still required to move the bag to the end of the collecting cylinder to ensure all the lid material is inside. Clearly, this bagging device still requires manual intervention and does not achieve fully automated bagging. Summary of the Invention

Detailed Implementation

[0016] like Figure 1 As shown, this bagging machine includes a frame 1, a feeding mechanism 2, a pushing mechanism 3, and a bagging film roll 15. The feeding mechanism 2 is used to convey stacks of horizontally arranged materials W forward (material W is not limited to cup lids; disposable bowls, plates, cups, toys, etc. are also suitable for this type of bagging packaging). The pushing mechanism 3 is used to push the materials into the bag D that comes out of the bagging film roll 15 (e.g., ...). Figure 6 (As shown).

[0017] like Figure 1 As shown, the feeding mechanism 2 includes a grid conveyor belt 20, in which a row of materials is placed in each grid slot of the grid conveyor belt 20; as Figure 3 As shown, this pushing mechanism 3 includes a pushing rod 30 and a pushing power source 31 that drives the pushing rod 30 to move back and forth. Driven by the pushing power source 31, the pushing rod 30 can push a row of materials forward.

[0018] To achieve bagging, such as Figure 2 As shown, a bagging platform 5, a front heat-sealing mechanism 6, a rear heat-sealing mechanism 7, a bag feeding mechanism 8, and a bag opening mechanism 4 are installed on the frame 1. The bagging platform 5 is located between the front heat-sealing mechanism 6 and the rear heat-sealing mechanism 7, and the bag opening mechanism 4 is located between the feeding mechanism 2 and the rear heat-sealing mechanism 7. The front heat-sealing mechanism 6 includes a cutter 61 and two front heat-sealing molds 60, and the rear heat-sealing mechanism 7 includes two rear heat-sealing molds 70. The bag feeding mechanism 8 includes a bag clamping component 80, a moving base 81, and a bag clamping power source 8. 2. The bag feeding power source (not shown) is also present. The bag clamping component 80 and the bag clamping power source 82 are both mounted on the movable seat 81. The bag clamping power source 82 can drive the bag clamping component 80 to perform the bag clamping action. The bag feeding power source can drive the movable seat 81 to move. The bag clamping component 80 can send the bag head to the bag opening mechanism 4. The bag opening mechanism 4 includes two bag opening clamping assemblies 40, one above the other. The bag opening clamping assembly 40 includes two clamping surfaces 400 and a clamping power source (not shown) that drives the two clamping surfaces 400 to clamp together.

[0019] like Figure 6 As shown, during bagging, the bag-feeding mechanism 8's clamping power source 82 drives the bag-clamping component 80 to clamp the bag D. Driven by the bag-feeding power source, the bag is then sent to the bag-opening mechanism 4 (e.g., ...). Figure 6 (From the left side), the bag opening mechanism 4's bag opening clamping assembly 40 clamps the bag opening, keeping it in the open state while simultaneously fixing it in place. Then, the bag feeding mechanism 8 moves backward to reset (as shown). Figure 6 (To the right) The pushing power source 31 of the pushing mechanism 3 drives the pushing rod 30 to push the material W into the bag D. Then the pushing rod 30 is reset, the front heat sealing mechanism 6 heat seals the front end of the bag, and at the same time the cutter 61 cuts the bag. Then the rear heat sealing mechanism 7 heat seals the rear end of the bag (i.e. the head of the bag), thus completing the material bagging work.

[0020] Of course, the above-mentioned bag feeding mechanism 8 can only achieve bag feeding when multiple bag clamping members 80 forming a ring are used to fully open the bag opening. However, this structure increases the complexity and instability of the bag feeding mechanism 8. To solve this problem, such as... Figure 2 As shown, a bag-supporting mechanism 9 is provided on the frame 1. The bag-supporting mechanism 9 is located between the bag-feeding mechanism 8 and the bag-opening mechanism 4. Figure 4 As shown, the bag-supporting mechanism 9 includes a sliding seat 90, a bag-supporting rod seat 91, and multiple bag-supporting rods 92. The multiple bag-supporting rods 92 are mounted on the bag-supporting rod seat 91 and face the bag-opening mechanism 4. The bag-supporting rod seat 91 is located on the sliding seat 90. A guide rail 11 is provided on the frame 1, and the sliding seat 90 is slidably mounted on the guide rail 11. The sliding seat 90 is connected to the bag-feeding power source. The movable seat 81 of the bag-feeding mechanism 8 is slidably mounted on the guide rail 11. The sliding seat 90 and the movable seat 81 are connected (through a connecting rod, a cylinder, or as an integral unit). Driven by the bag-feeding power source, the sliding seat 90 moves, and because the sliding seat 90 is connected to the movable seat 81, the movable seat 81 also moves accordingly.

[0021] The working principle of this bagging machine will be explained in detail below with reference to the bag-supporting mechanism 9: Figure 6 and Figure 7 As shown, during operation, the bag clamping power source 82 drives the bag clamping component 80 to clamp the bag onto the movable seat 81 (of course, other components are installed on the movable seat 81, so that the bag clamping component 80 acts on the movable seat 81; in addition, the bag clamping component 80 can also adopt other structures, as long as it can clamp the bag, it is a bag clamping component 80), while the bag supporting mechanism 9's bag supporting rod seat 91 and multiple bag supporting rods 92 are located inside the bag (before starting the machine, let the bag D be placed outside the bag supporting rod seat 91 and multiple bag supporting rods 92), and the multiple bag supporting rods 92 can open the bag (e.g. Figure 7 (at step 1 in the process), then the bag feeding power source drives the sliding seat 90 to move on the guide rail 11 in the direction of the bag opening mechanism 4 ( Figure 6(To the left of the center), since the sliding seat 90 is connected to the moving seat 81, the moving seat 81 also moves along the guide rail 11 in the direction of the bag opening mechanism 4. Figure 6 (To the left of the middle), so that the bag clamping component 80 can clamp the bag and move it to the left. When the head of the bag reaches the position of the bag opening mechanism 4, both the sliding seat 90 and the moving seat 81 stop moving. Since the multiple bag support rods 92 keep the bag opening open, the two bag opening clamping components 40 of the bag opening mechanism 4 can clamp the upper and lower sides of the bag opening (there is space between the two bag support rods 92 to allow the clamping surface 400 to clamp), keeping the bag opening open and fixing the bag opening. At this time, the bag clamping component 80 does not The bag is then clamped, and the feeding power source drives the sliding seat 90 and the moving seat 81 to move back to their original positions (as in step 2 of 7). The feeding power source 31 of the feeding mechanism 3 drives the feeding rod 30 to push the material into the bag. After that, the feeding rod 30 is reset. The front heat sealing mold 60 of the front heat sealing mechanism 6 heat seals the front end of the bag, while the cutter 61 cuts the bag. The rear heat sealing mold 70 of the rear heat sealing mechanism 7 heat seals the rear end of the bag (as in steps 4-5 of 7), thus forming a complete material bag.

[0022] like Figure 7 As shown in step 5, just after the cutter 61 cuts off the bag, the bag opening of the continuous bag section will extend beyond the front end of the support rod 92. The bag opening may retract inward, which may cause the bag opening mechanism 4 to fail to clamp the bag opening during the next bagging operation (because the edge of the bag opening needs to enter between the two clamping surfaces 400; if the edge of the bag opening retracts inward, it cannot enter). To solve this problem, the sliding seat 90 and the moving seat 81 are connected by a cylinder 83, an electric cylinder, or a hydraulic cylinder (the electric cylinder includes ordinary electric cylinders, as well as structures with motor-driven connecting rods moving back and forth). Figure 7 As shown in steps 5-6, after the cutter 61 cuts the bag, the clamping part 80 clamps the bag again, waiting for the next bagging operation. Then, the cylinder 83 drives (taking a cylinder as an example) to move the moving seat 81 forward (as shown in steps 5-6). Figure 6 (Move to the right while the sliding seat 90 remains stationary) This will cause the bag clamping component 80 to pull the bag forward a certain distance, so that the bag opening is completely on the bag support rod 92. The bag support rod 92 can open the edge of the bag opening, thus ensuring that the bag opening mechanism 4 can stably clamp the bag opening each time.

[0023] To ensure that the bag support rod seat 91 and the bag support rod 92 are inside the bag, such as Figure 4 As shown, an upper roller 98 is installed at the bottom of the bag support rod seat 91, and a lower roller 97 is installed on the sliding seat 90. The upper roller 98 contacts the lower roller 97, as shown. Figure 6As shown, the bottom edge of the bag D passes between the upper roller 98 and the lower roller 97 (roller-to-roll contact reduces friction). Two roller seats 94 are installed on the sliding seat 90, each with two rows of outer rollers 95. Inner rollers 96 are installed on both sides of the bag support rod seat 91, positioned inside the two rows of outer rollers 95 (the two rows of outer rollers 95 restrain the inner rollers 96, preventing the bag support rod seat 91 from sliding back and forth). Figure 4 As shown, the side of the bag passes between the inner roller 96 and the outer roller 95. This structure not only facilitates the passage of the bag but also reduces friction on the bag and makes it easier to place the bag support rod seat 91.

[0024] like Figure 4 As shown, the front end of the bag support rod seat 91 has a pointed tip. When the bag support mechanism 9 is reset, the front end of the bag support rod seat 91 will not scrape the inside of the bag, ensuring that the bag is not damaged.

[0025] Some materials are relatively flat (such as cup lids), and the material at the front may tip forward during the pushing process. Therefore, such as Figure 4 As shown, a baffle rod 93 is connected to the bag support rod seat 91, and the baffle rod 93 is arranged opposite to the push rod 30. When the bag support mechanism 9 approaches the push mechanism 3, the push rod 30 of the push mechanism 3 and the baffle rod 93 of the bag support mechanism 9 clamp the material, and the two move forward with the material clamped and send it into the bag, thus ensuring that the material enters the bag smoothly.

[0026] However, before heat sealing, the baffle rod 93 needs to move forward further (otherwise it will interfere with the front heat sealing mechanism 6). After the baffle rod 93 moves forward, the material may tip over. Therefore, as... Figure 6 As shown, a front bag-collecting mechanism is provided on the rear side of the front heat-sealing mechanism 6. The front bag-collecting mechanism includes two upper and lower front bag-collecting plates 12 and a front bag-collecting power source that drives the two front bag-collecting plates 12 to move relative to each other. A rear bag-collecting mechanism is provided on the front side of the rear heat-sealing mechanism 7. The rear bag-collecting mechanism includes two upper and lower rear bag-collecting plates 13 and a rear bag-collecting power source that drives the two rear bag-collecting plates 13 to move relative to each other. When the push rod 30 and the stop rod 93 clamp the material and feed it into the bag, the two front bag-collecting plates 12 gradually approach each other (not completely closed to prevent interference with the stop rod 93), so that the front end of the bag begins to contract (e.g., Figure 7 As shown in step 3), this prevents the material from tipping over; similarly, the two rear bag-collecting plates 13 gradually move closer together, causing the rear end of the bag to begin to contract (as shown in step 3). Figure 7 (As shown in step 3), this prevents the material from tipping over, thus ensuring the stability of the bag.

[0027] like Figure 5As shown, a support mechanism is provided at the location of the bag opening mechanism 4. The support mechanism includes two support rods 16 located on the left and right sides of the bag opening clamping assembly 40, and a support power source that drives the two support rods 16 to move in opposite directions. Before the post-heat sealing mechanism 7 performs heat sealing, the support power source drives the two support rods 16 to move in opposite directions, pulling the bag opening flat from left to right. This allows the upper and lower heat-sealed edges of the bag opening to fit more smoothly during the post-heat sealing mechanism 7, resulting in better sealing after heat sealing.

[0028] After the materials are bagged, the bagged products need to be removed. To enable automatic removal of the bagged products, such as... Figure 2 As shown, a feeding mechanism is provided on one side of the bagging platform 5. The feeding mechanism includes a feeding plate 10 and a feeding power source that drives the feeding plate 10 to move left and right. After the material is bagged, the feeding power source drives the feeding plate 10 to move, and the feeding plate 10 can push the bagged product out.

[0029] In order to push the material to one side (towards the bagging direction), a material handling mechanism is provided on one side of the feeding mechanism 2. The material handling mechanism includes a material handling plate 14 and a material handling power source that drives the material handling plate 14 to move back and forth. Driven by the material handling power source, the material handling plate 14 can push the material to one side, which is convenient for the subsequent pushing mechanism 3 to push.

[0030] Finally, it is worth mentioning that a baffle plate 21 is provided on one side of the grid conveyor belt 20. The material guide plate 14 pushes the material and allows it to rest against the baffle plate 21. One end of the baffle plate 21 has a discharge port 22. The push rod 30 can push the material out of the discharge port 22, thereby enabling the subsequent bagging work.
