DETAILED DESCRIPTION

[0036] The present invention is further described in conjunction with the following examples.

[0037] Example 1

[0038] One of the specific embodiments of the present invention is suitable for the automatic double-top bagging equipment of kraft paper, see Figure 1 The equipment includes a bag loading conveyor belt 3, a double bag loading device 1, a bag holding and clamping device 2 and a pushing device 5 arranged in sequence along the bag loading conveying direction, and a bag opening device is arranged above the bag holding and clamping device 2. It should be noted that the bag loading conveyor belt 3 is a conveyor belt with a negative pressure adsorption function, which can adsorb the paper bags transferred to the bag loading conveyor belt 3 to ensure that the entire paper bag will not be sucked up during the bag opening process.

[0039] In this embodiment, combined with Figure 2The double bagging device 1 includes a silo 12 for loading paper bags. In order to reduce the labor intensity of workers and improve the smoothness of bagging, two silos 12 are provided, and each silo 12 is installed on a base 11. Each silo 12 can slide relative to the base 11 in the longitudinal direction. The base 11 is provided with a first longitudinal moving mechanism for driving each silo 12 to move in the longitudinal direction. It should be noted that the first longitudinal moving mechanism can adopt a screw transmission mechanism composed of a screw, a nut, a slider fixed to the nut, a slide rail slidably matched with the slider, and a motor. The screw transmission mechanism has high structural precision, thereby improving the working smoothness of the equipment. By providing two silos 12, the problem of stopping the machine to replenish the silo 12 can be avoided. This is because, if only one silo 12 is provided, when the kraft paper bags in the silo 12 are used up, the machine needs to be stopped to fill the silo 12 with kraft paper bags, which undoubtedly reduces production efficiency. By providing two silos 12, when the paper bags in one of the silos 12 are used up, the first longitudinal moving mechanism can control the movement of the silo 12, so that the empty silo 12 is moved out of the working station, while the other silo 12 can continue to supply materials, which undoubtedly improves production efficiency and solves the problem of needing to stop the machine for bagging in the past.

[0040] In this embodiment, combined with Figure 2 Each silo 12 includes a bottom plate 14 and a first lifting mechanism 13 for driving the bottom plate 14 to move up and down in the vertical direction. It should be noted that the first lifting mechanism 13 can be a screw transmission mechanism consisting of a screw, a nut, a slider fixed to the nut, a slide rail slidably matched with the slider, and a motor. The screw transmission mechanism has high structural precision, thereby improving the working smoothness of the equipment. Of course, transmission mechanisms such as cylinders can also be used, as long as the bottom plate 14 can be lifted and lowered. Figure 3 A side plate 15 is fixedly installed on the side of each silo 12, and a U-shaped separator 16 placed laterally is fixedly connected to the end of the side plate 15. The U-shaped separator 16 can separate the two paper bags. Because the paper bags may be adhered to each other, and the upper bag suction mechanism may suck two bags when sucking them, the U-shaped separator 16 can be used to scrape the sides of the two paper bags, so that the paper bags located below fall back into the silo 12, ensuring the normal movement of the work.

[0041] In this example, see Figure 2The double bagging device 1 also includes a bagging suction mechanism for conveying the paper bags in the silo 12 to the bagging conveyor belt 3. The bagging suction mechanism includes a plurality of suction nozzles (not shown in the figure), and the plurality of suction nozzles are fixedly mounted on the mounting plate 17. The bagging suction mechanism also includes a second lifting mechanism for driving the mounting plate 17 to rise and fall in the vertical direction, and a synchronous belt mechanism 19 for driving the second lifting mechanism to reciprocate in the lateral direction. The synchronous belt mechanism 19 is a conventional synchronous belt mechanism 19 on the market, and the mounting plate 17 and the suction nozzle are both conventional mounting plates 17 and suction nozzles on the market, and the second lifting mechanism includes a bag taking cylinder 18. The bag taking cylinder 18 is set as a driving source to drive the plurality of suction nozzles to perform up and down lifting and reciprocating motion in the vertical direction. As long as the paper bags in the silo 12 can be sucked and transferred, the number of suction nozzles can be set according to actual needs.

[0042] In this embodiment, combined with Figure 4 and Figure 5 The bag opening device includes a bag opening suction mechanism for sucking the side of the paper bag and located above the upper bag conveyor belt 3. Specifically, the bag opening suction mechanism includes two bag opening cylinders 21 located above the upper bag conveyor belt 3 and arranged at intervals in the transverse direction. Of course, three or more bag opening cylinders 21 can also be set, and the specific setting can be selected according to actual needs. A suction cup 22 is fixedly installed at the end of the telescopic rod of each bag opening cylinder 21.

[0043] The working process of the combination of the double bag loading device 1 and the bag opening device is as follows: first fill the paper bags in the two silos 12, then start the equipment, the first longitudinal moving mechanism drives one of the silos 12 to move to the bottom of the bag loading suction mechanism, and the telescopic rod of the bag taking cylinder 18 moves, thereby driving the mounting plate 17 and multiple suction nozzles to move in the vertical direction into the silo 12 to suck the paper bags. After the suction is completed, the bag taking cylinder 18 returns to its original position, and then the synchronous belt mechanism 19 drives the mounting plate 17, multiple suction nozzles and paper bags to move to the bottom of the bag loading mechanism. The bag is transferred to the starting end of the upper bag conveyor belt 3, and then the bag taking cylinder 18 reciprocates again to place the paper bag on the upper bag conveyor belt 3, and then the negative pressure mechanism of the upper bag conveyor belt 3 adsorbs the bottom surface of the paper bag, and then under the action of the upper bag conveyor belt 3, the paper bag is transported to the station of the bag opening device, and then each bag opening cylinder 21 drives its telescopic rod to move downward, so that the suction cup 22 is on the side of the paper bag facing upward, and then the telescopic rod returns to its position to open the opening of the paper bag, thereby completing the bagging and bag opening processes.

[0044] Combination Figure 6The bag support and clamping device 2 includes a material conveyor belt 4 vertically arranged with the upper bag conveyor belt 3. The material conveyor belt 4 is a conventional conveyor belt on the market, and as an improvement, the top surface of the material conveyor belt 4 is provided with a pair of limit strips 41 that can move toward or away from each other, so as to adjust the distance between the two limit strips 41, so as to be suitable for conveying materials of various specifications. As another improvement, combined with Figure 7 At least one guide block 42 is provided at the end of the material conveyor belt 4. The top surface of the guide block 42 is a guide slope inclined upward. By setting the guide slope, the conveying direction of the material can be guided. Moreover, since the guide slope is set obliquely upward, it can make the material separate from the conveyor belt during the pushing process, thereby forming a certain pushing gap between the material and the material conveyor belt 4, getting rid of the friction between the material conveyor belt 4 and the material, so that the material is smoother during the pushing process and bagging is more convenient.

[0045] Combination Figure 8 The bag-opening and bag-clamping device 2 includes a bag-opening mechanism 6 for opening the paper bag on the upper bag conveyor belt 3. Specifically, Fig. 9 The bag-supporting mechanism 6 includes a pair of duckbill pieces 51 located above the end of the material conveyor belt 4, and a pushing channel 52 is formed on the inner side of the duckbill piece 51 for inserting the pusher 77. The bag-supporting mechanism 6 also includes a second longitudinal moving mechanism that drives the duckbill piece 51 to move in the longitudinal direction, and the second longitudinal moving mechanism includes a rotatable transmission shaft 53, and a cam 54 is sleeved and fixed on the outer peripheral side of the transmission shaft 53. The transmission shaft 53 is rotatably mounted on a machine base, and the machine base has a top plate 60, wherein the attached Fig. 9 The top plate 60 is hidden. The side of the duckbill 51 is fixed to the transmission rod 56 through the connecting member 55. The bottom end of the transmission rod 56 is fixedly connected to the first bearing 50. The side of the first bearing 50 abuts against the inner wall of the base. The outer peripheral side of the transmission rod 56 is sleeved and fixed with a second linear slide 561. The inner side of the base is fixedly installed with a second linear slide rail 57. The second linear slide rail 57 is slidably matched with the second linear slide 561. The bottom end of the second linear slide 561 is installed with a second bearing 59. The outer peripheral side of the second bearing 59 abuts against the outer peripheral side surface of the cam 54. Of course, the bottom end of the transmission rod 56 can also directly abut against the outer peripheral side surface of the cam 54.

[0046] The working process of the bag-holding mechanism 6 is as follows: if the bag needs to be held, the transmission shaft 53 rotates, and the transmission shaft 53 rotates and drives the cam 54 to rotate. The cam 54 rotates, and its changing trajectory drives the second bearing 59 to reciprocate in the longitudinal direction. The reciprocating motion of the second bearing 59 is converted into the sliding of the second linear slide 561 relative to the second linear slide rail 57, thereby indirectly converted into the reciprocating motion of the duckbill 51 in the longitudinal direction, thereby realizing the insertion of the duckbill 51 into the opening of the paper bag or removal of the paper bag.

[0047] The bag-stretching and bag-clamping device 2 further comprises a bag-clamping mechanism 7 for cooperating with the bag-stretching mechanism 6 to clamp the paper bag. Fig.10 The bag clamping mechanism 7 includes a clamping member 61 located on the side of the duckbill member 51, the clamping member 61 is fixedly mounted on the front end of the rotating member 62, the rotating member 62 is rotatably mounted on the base 58 through a rotating shaft, and the rear end of the rotating member 62 is provided with a bag clamping cylinder 64 for driving the rotating member 62 to rotate, and the bag clamping cylinder 64 is fixedly connected to the rear end of the rotating member 62 through a second connecting rod assembly 63.

[0048] The working process of the bag holding and clamping device 2 is as follows: if bag clamping is required, the bag clamping cylinder 64 drives its telescopic rod to extend, thereby driving the rotating member 62 to rotate. When the rotating member 62 rotates, the clamping member 61 on the rotating member 62 moves close to the duckbill member 51 and cooperates with the duckbill member 51 to clamp the paper bag.

[0049] Combination Fig.11 and Fig.12 The pushing device 5 includes a pushing mechanism for pushing the material on the material conveyor belt 4 into the paper bag on the upper bag conveyor belt 3. Specifically, the pushing mechanism includes first linear slides 71 arranged in pairs on both sides of the material conveyor belt 4, each first linear slide 71 is provided with a first linear slide 72 that is slidably matched therewith, and a pushing shaft 73 is passed through the two first linear slides 72, and the pushing shaft 73 can rotate relative to each first linear slide 72, and a vertical and inverted pushing cylinder 75 is fixedly installed on one of the first linear slides 72, and the telescopic rod of the pushing cylinder 75 extends downward, and the end of the telescopic rod is connected to the pushing shaft 73 through the first connecting rod assembly 76, so that the movement of the telescopic rod of the pushing cylinder 75 drives the pushing shaft 73 to move, and two pushers 77 for pushing materials and located above the material conveyor belt 4 are fixedly installed on the outer peripheral side of the pushing shaft 73. The beginning of the push handle 77 is fixedly connected to the push shaft 73, and the end of the push handle 77 extends downward to form a push portion 78. The area from the beginning of the push to the end of the push handle 77 is an inclined portion arranged obliquely downward, and the inclined portion is provided with a plurality of hollow holes, which can reduce weight and save materials. The push mechanism also includes a crank connecting rod mechanism 79 that drives one of the first linear slides 72 to reciprocate.

[0050] The working process of the pushing device 5 is as follows: before pushing is needed, the telescopic rod of the pushing cylinder 75 is retracted, and the rotating shaft is rotated to lift the push handle 77 to avoid contacting the material on the material conveyor belt 4. If pushing is needed, the telescopic rod of the pushing cylinder 75 is extended to drive the rotating shaft to rotate, so that the push handle 77 lowers its head, and the pushing part 78 of the push handle 77 contacts the material conveyor belt 4. Then the crank connecting rod structure moves, driving the first linear slide 72 to make a reciprocating motion along the first linear slide rail 71, thereby indirectly causing the push handle 77 to push the material into the paper bag and then retract, completing a material pushing process. In addition, since the duckbill 51 is provided with a pushing channel 52, and the push handle 77 can be inserted into the pushing channel 52, the two duckbill pieces 51 can only limit the material, and can also limit the displacement of the push handle 77 during pushing, thereby improving the smoothness and stability of bagging.

[0051] The working process of the automatic double bagging equipment for kraft paper in this embodiment is as follows: first, the paper bag is placed in the silo 12, the bag suction mechanism transfers the paper bag in the silo 12 to the bag conveyor belt 3, the bag conveyor belt 3 transfers the paper bag to the station of the bag support and clamping device 2, then the bag opening suction mechanism absorbs the side of the paper bag and opens the paper bag, then the bag support mechanism 6 is inserted into the paper bag and opens the opening of the paper bag, while opening, the bag clamping mechanism 7 clamps the paper bag, and finally, the pushing mechanism pushes the material on the material conveyor belt 4 into the paper bag, completing the bagging of the kraft paper bag, the bag support and clamping device 2 is reset, the bag opening device is reset, and the bag conveyor belt 3 continues to convey the paper bag to the next station, completing the entire bagging process. Compared with the prior art, its structure is simple and compact, and it can automatically complete the bagging and bagging work, replacing the previous manual filling method, improving work efficiency, saving labor costs, reducing the labor intensity of workers, and improving the quality of filled products.

[0052] The upper bag suction mechanism includes a rotating shaft rotatably mounted above the upper bag conveyor belt 3, a rotating plate being fixedly connected to the end of the rotating shaft, and a driving assembly for driving the rotating shaft to rotate is provided at the other end of the rotating shaft; at least two telescopic cylinders are fixedly mounted on the outward side of the rotating plate, and each telescopic cylinder is arranged on the rotating plate at intervals along the circumference of the rotating shaft, a first suction nozzle is fixedly mounted on the end of the telescopic rod of the first telescopic cylinder, and a second suction nozzle is fixedly mounted on the end of the telescopic rod of the second telescopic cylinder, and both the first suction nozzle and the second suction nozzle are connected to an external negative pressure device.

[0053] The silo 12 is fixedly mounted above the upper bag suction mechanism.

[0058] It should be noted that the material bin can be arranged above the casing 10 .
