[0064] Example 1

[0065] See Figure 1 to Figure 14 As shown in the figure, this embodiment discloses a specific implementation of an M-bag feeding and waste edge trimming device.

[0066] M-bag feeding and waste trimming device, see Figure 1 to 1. Figure 14 As shown, the system includes a feeding assembly 1, a bag-supporting assembly 2, a transfer assembly 3, a receiving belt 4, a vacuum assembly 5, a heat-sealing assembly 6, a waste-edge trimming assembly 7, and a waste-edge recycling assembly 8. The bag-supporting assembly 2 opens the bag opening 91 of the M-bag 9, and the feeding assembly 1 loads several stacked material trays into the M-bag 9. The transfer assembly 3 transfers the M-bag 9 containing several stacked material trays to the receiving belt 4 with the bag open. The transfer assembly 3 includes a moving module 31 and a first moving plate 32 and a second moving plate 33 driven by the moving module 31. A first molding assembly 34 is provided at the first end of the first moving plate 32, and the second moving plate 33 is provided at the second moving plate 33. A second molding component 35 is provided at the first end of plate 33, and a transverse connecting plate 36 is provided at the bottom of the second end of the first moving plate 32 and the second moving plate 33. A first finger-clamping cylinder 37 is provided below the transverse connecting plate 36. When the first molding component 34 and the second molding component 35 are in the feeding position, the first finger-clamping cylinder 37 clamps one side of the heat-sealed M bag 9, and the waste edge cutting component 7 cuts off the waste edge. When the first molding component 34 and the second molding component 35 are above the receiving belt 4, the first finger-clamping cylinder 37 transfers the clamped waste edge 10 to the waste edge recycling component 8.

[0067] Specifically, referring to Figure 1, specifically Figure 1(a), the cross-sections of both sides of bag M9 are M-shaped, with two layers in the middle and four layers on both sides; Figure 1(b) is a schematic diagram of bag M9 carrying several stacked material trays in an open state; see... Figure 2The purpose of this embodiment is to place several stacked material trays into M bag 9 and transfer M bag 9 to receiving belt 4. On receiving belt 4, M bag 9 is changed, vacuumed, heat-sealed and waste edge is cut off. When transferring the next M bag 9, waste edge 10 is changed to waste edge recycling component 8. This embodiment makes full use of the transfer process of transfer component 3 to achieve efficient feeding into M bag 9, transfer of M bag and cutting off waste edge.

[0068] See Figure 6 and Figure 7 The feeding assembly 1 works as follows: The feeding assembly 1 includes a horizontal module 11 and a lifting assembly 12 that moves horizontally along the horizontal module 11; the lifting assembly 12 includes a lead screw 121, a first lifting bracket 122, a connecting block 123, and a gripper 124, wherein the lead screw 121 and the connecting block 123 are configured to cooperate; the lead screw 121 drives the first lifting bracket 122 to rise and fall along the connecting block 123, and the gripper 124 is disposed at the bottom of the first lifting bracket 122; the gripper 124 includes a clamping cylinder 1241. The clamping cylinder 1241 drives a first L-shaped clamping plate 1242 and a second L-shaped clamping plate 1243. The first L-shaped clamping plate 1242 has several anti-slip textures on its inner side, and the second L-shaped clamping plate 1243 has several anti-slip textures on its inner side. The connecting block 123 includes a vertical plate 1231, a connecting plate 1232, and a slider 1233. The vertical plate 1231 is movably mounted on the horizontal module 11 via a horizontal slide rail 111. The connecting plate 1232 is fixedly mounted on the vertical plate 1231, and the slider 1233 is fixedly mounted on... Mounted on the connecting plate 1232, the lead screw 121 passes through the slider 1233. The lead screw 121 and the slider 1233 cooperate to form a lead screw drive mechanism. The connecting plate 1232 cooperates with the first lifting bracket 122 via a vertical slide rail 125. To effectively utilize the space between the lifting assembly 12 and the horizontal module 11, the lead screw 121 and the slider 1233 are positioned behind the first lifting bracket 122 but not centered. This non-centered positioning provides installation space for the vertical slide rail 125 between the connecting plate 1232 and the first lifting bracket 122. The structure is compact. After the clamping cylinder 1241 drives the first L-shaped clamping plate 1242 and the second L-shaped clamping plate 1243 to clamp several layers of material trays, the first lifting bracket 122 is driven to rise and fall along the connecting plate 1232 under the cooperation of the lead screw 121 and the slider 1233, thereby lifting several layers of material trays. Then, the horizontal module 11 changes the horizontal position of several layers of material trays. After reaching the predetermined position, the first L-shaped clamping plate 1242 and the second L-shaped clamping plate 1243 are released, and several layers of material trays are put into the M bag at once, which is efficient and saves manpower.

[0069] See Figure 4 and Figure 14The working principle of the waste edge recycling component 8 is as follows: The waste edge recycling component 8 includes a telescopic cylinder 81, a mounting plate 82, clamping fingers 83, a V-shaped guide plate 84, and a recycling container 85; the waste edge 10 is clamped by the clamping fingers 83 after passing through the V-shaped guide plate 84. The telescopic cylinder 81 drives the clamping fingers 83 to move above the recycling container 85 through the mounting plate 82, releases the clamping fingers 83, and releases the waste edge 10 into the recycling container 85; after the waste edge of one M bag is cut off, the waste edge 10 is clamped by the first clamping finger cylinder 37. When the transfer component 3 transfers the next M bag, the waste edge 10 is guided by the V-shaped guide plate 84 and then transferred to the clamping fingers 83. The telescopic cylinder 81 drives the clamping fingers 83 to move above the recycling container 85 through the mounting plate 82, and then releases the waste edge 10. This fully utilizes the transfer process of the transfer component 3 and improves the efficiency of cutting waste edges of M bags.

[0070] See Figure 4 and Figure 14 The working principle of the bag support assembly 2 is as follows: The bag support assembly 2 includes a first bag support assembly 21 and a second bag support assembly 22; the first bag support assembly 21 includes a first horizontal telescopic cylinder 211, a first lifting cylinder 212 and a second finger-clamping cylinder 213, the second finger-clamping cylinder 213 drives the first vertical bag support plate 214 and the second vertical bag support plate 215 to move closer or further apart; the second bag support assembly 22 includes a second horizontal telescopic cylinder 221, a second lifting cylinder 222 and a third finger-clamping cylinder 223. 3. The third clamping cylinder 223 drives the third vertical bag support plate 224 and the fourth vertical bag support plate (not shown due to obstruction) to move closer or further apart from each other; the position between the first bag support assembly 21 and the second bag support assembly 22 is the feeding station of the M bag. The first vertical bag support plate 214, the second vertical bag support plate 215, the third vertical bag support plate 224 and the fourth vertical bag support plate respectively support the four corners of the bag opening 91 of the M bag 9. In this state, it is convenient for the feeding assembly 1 to put the clamped layers of stacked materials into the M bag 9.

[0071] See Figures 8 to 11The working principle of the transfer component 3 is as follows: The first molding component 34 includes a first support 341, a first cylinder 342, a first suction cup 343, a first mounting plate 344, a second cylinder 345, and a first vertical clamping plate 346; the second molding component 35 includes a second support 351, a third cylinder 352, a second suction cup 353, a second mounting plate 354, a fourth cylinder 355, and a second vertical clamping plate 356; the first cylinder 342 drives the first suction cup 343 to extend and retract, and the third cylinder 352 drives the second suction cup 353 to extend and retract, with the first suction cups 343 moving closer to or further away from the second suction cup 353. The second cylinder 345 drives the first vertical clamping plate 346 to extend and retract, and the fourth cylinder 355 drives the second vertical clamping plate 356 to extend and retract. The first vertical clamping plates 346 move closer to or further away from the second vertical clamping plate 356. The M bag 9 includes a bag opening 91 and a bag body 92. The first suction cup 343 and the second suction cup 353 respectively adhere to the outer sides of the bag opening 91 of the M bag. The first vertical clamping plate 346 and the second vertical clamping plate 356 respectively clamp the two sides of the bag body 92 of the M bag. The height of the first vertical clamping plate 346 and the second vertical clamping plate 356 is slightly smaller than that of the bag body 92 of the M bag. The height of 2 allows the first vertical clamping plate 346 and the second vertical clamping plate 356 to clamp almost the entire height range of the bag body 92; the specific working principle is as follows: the first cylinder 342 is installed inside the first bracket 341, and the third cylinder 352 is installed inside the second bracket 351; the first mounting plate 344 is installed below the first bracket 341, and the second mounting plate 354 is installed below the second bracket 351; a third slide rail 3441 is installed below the first mounting plate 344, and a fourth slide rail 3541 is installed below the second mounting plate 354; the first... Two cylinders 345 drive the first vertical clamping plate 346 to move along the third slide rail 3441; the fourth cylinder 355 drives the second vertical clamping plate 356 to move along the fourth slide rail 3541; the M bag 9 contains several layers of material; when the M bag 9 is clamped (the first vertical clamping plate 346 and the second vertical clamping plate 356 clamp it) and the bag opening 91 is suctioned (the first suction cup 343 and the second suction cup 353 respectively suction the two sides of the outside of the bag opening 91), the moving module 31 drives the first moving plate 32 and the second moving plate 33 to move synchronously, so that the M bag 9 is transferred to the receiving belt 2.

[0072] See Figure 3 , Figure 12 and Figure 15The working principle of the vacuum assembly 5 is as follows: The vacuum assembly 5 includes a third lifting cylinder 51, a fourth finger-clamping cylinder 52, a second lifting bracket 53, and a long strip-shaped vacuum suction nozzle 54. The vacuum suction nozzle 54 is installed on the second lifting bracket 53. The fourth finger-clamping cylinder 52 drives the first shaping plate 55 and the second shaping plate 56 to move closer or further apart. The vacuum suction nozzle 54 is located between the first shaping plate 55 and the second shaping plate 56, and all three are on the same vertical plane. A first suction assembly 57 and a second suction assembly 58 are respectively arranged on both sides of the vacuum assembly 5. The first suction assembly 57 includes a first telescopic module 571 and a third suction cup 572. The second suction assembly 58 includes a second telescopic module 581 and a fourth suction cup 582. The third suction cup 572 and the fourth suction cup 582 move closer to each other and suction the M bag 9. The third suction cup 572 and the first suction cup 343 are staggered in the height direction, and the fourth suction cup 582 and the second suction cup 353 are staggered in the height direction. When the M bag 9 is transferred to the receiving belt 4, the third suction cup 572 and the fourth suction cup 582 approach each other and adsorb the two sides of the bag opening 91 of the M bag 9, while the first suction cup 343 and the second suction cup 353 retract, so that the M bag 9 always remains open.

[0073] See Figure 12 and Figure 13 The heat-sealing assembly 6 includes a first telescopic cylinder 61, a first heat-sealing assembly 62, a second telescopic cylinder 63, and a second heat-sealing assembly 64. The first telescopic cylinder 61 drives the first heat-sealing assembly 62 to move, and the second telescopic cylinder 63 drives the second heat-sealing assembly 64 to move. The first heat-sealing assembly 62 includes a first heat-sealing strip 621, a second heat-sealing strip 622, and a first foam sealing strip 623. The first foam sealing strip 623 protrudes beyond the first heat-sealing strip 621 and the second heat-sealing strip 622. The second heat-sealing assembly 64 includes a third heat-sealing strip 641, a fourth heat-sealing strip 642, and a second foam sealing strip 643. The second foam sealing strip 643 protrudes beyond the third heat sealing strip 641 and the fourth heat sealing strip 642. The first heat sealing strip 621 and the third heat sealing strip 641 are paired to form a first heat seal 93, and the second heat sealing strip 622 and the fourth heat sealing strip 642 are paired to form a second heat seal 94. A gap is provided between the first heat sealing strip 621 and the second heat sealing strip 622, and the first foam sealing strip 623 is located below the second heat sealing strip 622. A gap is also provided between the third heat sealing strip 641 and the fourth heat sealing strip 642, and the second foam sealing strip 643 is located below the fourth heat sealing strip 642. See [link to relevant documentation]. Figure 2 The distance between the first heat seal 93 and the second heat seal 94 is 10mm-15mm. After heat sealing is completed, and along... Figure 2The dotted line L marks the waste edge. The waste edge cutting assembly 7 reciprocates along the top of the first heat sealing assembly 62. The waste edge cutting assembly 7 includes a cutting blade 71 and a relief groove 72 is provided above the third heat sealing strip 641. The cutting blade 71 and the relief groove 72 cooperate to cut off the waste edge 10. The heat sealing assembly 6 forms two heat seals on the M bag 5 after vacuuming and shaping by the vacuuming assembly 5.

[0074] The working process of the M-bag feeding and waste trimming device in this embodiment is as follows:

[0075] In the first step, the bag-supporting assembly 2 opens the bag opening 91 of the M bag 9, and the feeding assembly 1 loads several stacked material trays into the M bag 9.

[0076] In the second step, the transfer component 3 transfers the M bag 9, which carries several stacked material trays, to the receiving belt 4 with the bag open. The transfer component 3 then returns to its original position. Specifically, during the transfer of the M bag 9, the first suction cup 343 and the second suction cup 353 respectively adhere to the outer sides of the bag opening 91 of the M bag 9, and the first vertical clamping plate 346 and the second vertical clamping plate 356 respectively clamp the sides of the bag body 92 of the M bag 9, ensuring that the M bag is open and stably transferring the M bag 9 to the receiving belt 4. On the receiving belt 4, to ensure that the M bag is in the open state, the third suction cup 572 and the fourth suction cup 582 approach each other and adhere to the sides of the M bag 9, so that the M bag 9 is in the open state. The first moving plate 32 and the second moving plate 33 drive the first suction cup 343 and the second suction cup 353 to return to their original positions. The open state of the M bag is ensured by the third suction cup 572 and the fourth suction cup 582 after the change of hands.

[0077] In the third step, the vacuum assembly 5 vacuums the M bag 9 placed on the receiving belt 4; specifically, the third lifting cylinder 51 drives the vacuum suction nozzle 54 to insert into the open M bag 9. The vacuum suction nozzle 54 is a flat and narrow rectangle. The first shaping plate 55 and the second shaping plate 56 are respectively located at the fold line 95 of the open M bag 9, ready to fold the bag; the fourth finger-clamping cylinder 52 drives the first shaping plate 55 and the second shaping plate 56 to move closer to each other and fold the M bag 9. After folding, the third suction cup 572 and the fourth suction cup 582 return to their original positions.

[0078] In the fourth step, the M-bag after vacuumization by the heat-sealing assembly is heat-sealed; specifically, the first telescopic cylinder 61 drives the first heat-sealing assembly 62 to contact one side of the M-bag 9, and the second telescopic cylinder 63 drives the second heat-sealing assembly 64 to contact the other side of the M-bag 9. The vacuum suction nozzle 54 is clamped between the first foam cotton sealing strip 623 and the second foam cotton sealing strip 643. In order to press the vacuum suction nozzle 54 firmly, the first foam cotton sealing strip 623 and the second foam cotton sealing strip 643 deform. The vacuum suction nozzle 54 starts vacuumization to pump the air inside the M-bag 9 to a predetermined vacuum degree, such as a vacuum degree of 30%-70%. The third lifting cylinder 51 drives the vacuum suction nozzle 54 to rise and withdraw from the M-bag 9. During the withdrawal process, the first foam cotton sealing strip 623 and the second foam cotton sealing strip 643 always press the bag opening 91 tightly. The first heat-sealing assembly 62 and the second heat-sealing assembly 64 are activated to form a first heat seal 93 and a second heat seal 94 on both sides of the M-bag, and the two heat seals can effectively prevent air leakage.

[0079] In the fifth step, after the first finger clamping cylinder 37 clamps the scrap edge 10 formed after heat-sealing the M-bag, the scrap edge cutting assembly 7 cuts off the scrap edge 10; specifically, when the first M-bag completes heat-sealing, the transfer assembly 3 has already returned and received a second M-bag. The transverse connecting plate 36 and the first finger clamping cylinder 37 are located on one side of the first M-bag. Under the condition that the first finger clamping cylinder 37 clamps the scrap edge 10 on one side of the first M-bag, the scrap edge cutting assembly 7 moves along the top of the first heat-sealing assembly 62 and completes cutting off the scrap edge 10.

[0080] In the sixth step, the transfer assembly 3 transfers the next M-bag 9 carrying a plurality of stacked material trays to the receiving belt 4 in an open state, and the scrap edge 10 clamped by the first finger clamping cylinder 37 is transferred to the scrap edge recovery assembly 8. Specifically, the next M-bag 9 is the second M-bag in the seventh step. When the second M-bag is transferred to the receiving belt 4, the transverse connecting plate 36 and the first finger clamping cylinder 37 are transferred to above the clamping fingers 83. After the clamping fingers 83 clamp the scrap edge 10, the first finger clamping cylinder 37 releases the scrap edge 10, so that the scrap edge 10 is transferred to the clamping fingers 83. After the transverse connecting plate 36 and the first finger clamping cylinder 37 return, the telescopic cylinder 81 drives the clamping fingers 83 to move to above the recovery container 85 through the mounting plate 82, and then releases the scrap edge 10. This makes full use of the transfer process of the transfer assembly 3 and improves the efficiency of scrap edge cutting for M-bags.

[0081] Example 2

[0082] Refer Figure 16 As shown, this example discloses a specific embodiment of an M-bag feeding and scrap edge cutting method.

[0083] The M-bag feeding and scrap edge cutting method, refer Figure 16 As shown, adopting the M-bag feeding and scrap edge cutting device described in Example 1, includes the following steps:

[0084] Step S1: The bag-supporting assembly 2 opens the bag opening 91 of the M bag 9, and the feeding assembly 1 loads several stacked material trays into the M bag 9.

[0085] Step S2: The transfer component 3 transfers the M bag 9 carrying several stacked material trays in an open state to the receiving belt 4, and the transfer component 3 returns to its original position. Specifically, during the transfer of the M bag 9, the first suction cup 343 and the second suction cup 353 respectively adsorb the two sides of the outside of the bag opening 91 of the M bag 9, and the first vertical clamping plate 346 and the second vertical clamping plate 356 respectively clamp the two sides of the bag body 92 of the M bag 9, ensuring that the M bag is in an open state and stably transferring the M bag 9 to the receiving belt 4. On the receiving belt 4, in order to ensure that the M bag is in an open state, the third suction cup 572 and the fourth suction cup 582 approach each other and adsorb the two sides of the M bag 9, so that the M bag 9 is in an open state. The first moving plate 32 and the second moving plate 33 drive the first suction cup 343 and the second suction cup 353 to return to their original positions. The open state of the M bag is ensured by the third suction cup 572 and the fourth suction cup 582 after the change of hands.

[0086] Step S3: The vacuum assembly 5 vacuums the M bag 9 placed on the receiving belt 4; specifically, the third lifting cylinder 51 drives the vacuum suction nozzle 54 to insert into the open M bag 9. The vacuum suction nozzle 54 is a flat and narrow rectangle. The first shaping plate 55 and the second shaping plate 56 are respectively located at the fold line 95 of the open M bag 9, ready to fold the bag; the fourth finger-clamping cylinder 52 drives the first shaping plate 55 and the second shaping plate 56 to move closer to each other and fold the M bag 9. After folding, the third suction cup 572 and the fourth suction cup 582 return to their original positions.

[0087] Step S4: The M bag after vacuuming by the heat-sealing assembly is heat-sealed; specifically, the first telescopic cylinder 61 drives the first heat-sealing assembly 62 to contact one side of the M bag 9, and the second telescopic cylinder 63 drives the second heat-sealing assembly 64 to contact the other side of the M bag 9. The vacuum suction nozzle 54 is sandwiched between the first foam cotton seal 623 and the second foam cotton seal 643. To press the vacuum suction nozzle 54 firmly, the first foam cotton seal 623 and the second foam cotton seal 643 will deform; the vacuum suction nozzle 54 starts to vacuum and draws the M bag 9 to a predetermined vacuum degree, such as 30%-70% vacuum degree. The third lifting cylinder 51 drives the vacuum suction nozzle 54 to rise and pull away from the M bag 9. During the pulling process, the first foam cotton seal 623 and the second foam cotton seal 643 will always press the bag opening 91 tightly; the first heat-sealing assembly 62 and the second heat-sealing assembly 64 are activated to form a first heat seal 93 and a second heat seal 94 on both sides of the M bag. The two heat seals can effectively prevent air leakage.

[0088] Step S5: The first finger-clamping cylinder 37 clamps the waste edge 10 formed after heat sealing the M bag, and the waste edge cutting assembly 7 cuts off the waste edge 10; specifically, when the first M bag is heat sealed, the transfer assembly 3 has returned to its original position and received the second M bag, the transverse connecting plate 36 and the first finger-clamping cylinder 37 are on one side of the first M bag, and with the first finger-clamping cylinder 37 clamping one side of the first M bag, the waste edge cutting assembly 7 moves along the top of the first heat sealing assembly 62 and completes the cutting off of the waste edge 10.

[0089] Step S6: The transfer assembly 3 transfers the next M bag 9, which carries several stacked material trays, to the receiving belt 4 with the bag open. The waste edge 10 held by the first gripping finger cylinder 37 is transferred to the waste edge recycling assembly 8. Specifically, the next M bag 9 is the second M bag in step seven. When the second M bag is transferred to the receiving belt 4, the transverse connecting plate 36 and the first gripping finger cylinder 37 are transferred to the top of the gripping finger 83. After the gripping finger 83 clamps the waste edge 10, the first gripping finger cylinder 37 releases the waste edge 10, allowing the waste edge 10 to be transferred to the gripping finger 83. After the transverse connecting plate 36 and the first gripping finger cylinder 37 return to their original positions, the telescopic cylinder 81 drives the gripping finger 83 to move above the recycling container 85 through the mounting plate 82, and then releases the waste edge 10. This fully utilizes the transfer process of the transfer assembly 3 and improves the waste edge cutting efficiency of the M bag.
