Description

Technical Field

[0001] The present invention relates to the field of paper bag packaging for converting horizontal paper bags into vertical paper bags for stacking and packaging, and in particular to a paper bag baling machine integrating vertical stacking and packaging of paper bags. Background Art

[0002] Square-bottom paper bags are widely popular among consumers as environmentally friendly packaging. Paper bag balers stack and pack finished paper bags for easy packaging. In industrial production, paper bags are produced in large quantities, but the collection, stacking, and packaging of paper bags are all done manually, which is labor-intensive and inefficient. Furthermore, manually collected paper bags use less space during packaging. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a paper bag baling machine that integrates vertical stacking and packaging of paper bags and realizes full-automatic collection, sorting and bundling of paper bags, thereby improving space utilization.

[0004] To solve the above technical problems, the present invention solves the problem of a paper bag baling machine with integrated vertical stacking and packaging of paper bags through the following technical solutions, which are characterized by: comprising a frame, on which a bag turning part, a bag clamping and transporting part and a movable embracing and clamping part are sequentially arranged; the bag turning part, which turns and connects between the bag input part and the vertical bag carrying platform, the feeding end of the bag input part is provided with a bag opening turning part for turning the bag opening of the horizontal paper bag alternately forward and backward, the bag turning part is provided with a first channel, and the vertical bag carrying platform is provided with a second channel, when the bag body on the bag turning part is a vertical bag body, the first channel is connected to the second channel to form an integrated channel; the bag clamping and transporting part includes a push button which enters the first channel A lifting bag pushing rod group for feeding the integrated bag body and a lifting limit rod group cooperating with the lifting bag pushing rod group to transfer the bag body, the lifting bag pushing rod group and the lifting limit rod group are arranged relatively left and right on the vertical bag body carrying platform, the lifting bag pushing rod group and the lifting limit rod group are respectively connected with the driving device, and the driving device drives the lifting bag pushing rod group and the lifting limit rod group to move in the integration channel respectively; a mobile encircling clamping part, which is connected with the bag body clamping and transfer part for transportation, the mobile encircling clamping part includes a clamping arm group for clamping a part of the bag body, the clamping arm group has a clamping power source, and the clamping arm group is connected with the longitudinal drive mechanism. When the clamping arm group is working, the vertical bag body includes a clamping area for clamping and a bundling reserved area for bundling.

[0005] The horizontal bag of the present invention is fed into the bag turning part by the bag input part after being alternately turned forward and reversely by the bag opening turning part. The bag turning part turns 90 degrees to turn the horizontal bag (horizontally placed) into a vertical bag (standing state). The vertical bag is convenient for stacking and packaging. The driving device drives the lifting bag pushing rod group and the lifting limit rod group to move toward the bag turning part. At the same time, the lifting bag pushing rod group descends and moves to the bottom of the first channel and then rises to enter. The lifting limit rod group rises and moves forward to integrate the bag body and stops moving after it is in place. The integrated bag body is limited by the movement, and then the lifting bag pushing rod group and the lifting limiting rod group in the first channel cooperate to clamp the bag body pile, and move along the integration channel toward the horizontal bag body carrying platform. The bag body clamping and transporting part pushes the integrated bag body to the handover station, and the mobile embracing clamping part moves forward to both sides of the bag body clamping and transporting part. The bag body clamping and transporting part drops as a whole to release the bag body, and then the mobile embracing clamping part clamps the bag body partially and transfers it to the next bundling process, and bundles the reserved bundling area of the bag body. The present invention integrates and bundles the bag body after the bag mouth is alternately turned, so that the overall packaging of the bag body is more flat and beautiful. At the same time, automation can reduce manual participation, reduce labor intensity, and improve work efficiency. In addition, clamping and transferring are used in the process of transferring the bag body, which reduces the volume of the bag body pile, increases the number of bag bodies bundled per unit, and improves space utilization.

[0006] Preferably, the bearing surface of the bag input portion is not lower than the feeding end surface of the bag turnover portion, so as to make the bag conveying smoother.

[0007] Furthermore, the bag opening steering unit includes a turntable and a rotating pressure block that cooperates with the turntable to steer the bag opening. The rotating pressure block is positioned above the turntable, which is in transmission connection with a rotational power source, and the rotating pressure block is in transmission connection with a lifting power source. The rotating pressure block descends to press the bag on the turntable, and then the two cooperate to rotate the bag forward and reverse, causing the bag opening to be delivered in the forward and reverse directions, ensuring that the subsequent stack of bags is overall flat, facilitating subsequent packaging.

[0008] Furthermore, the bag input section includes a horizontal bag support platform and material sorting push plates, the material sorting push plates being disposed on either side of the horizontal bag support platform. The material sorting push plates are mounted on a movable seat, which slides along a material pushing track provided transversely parallel to the frame. The movable seat is in transmission connection with a synchronous avoidance drive component that moves back and forth with the movable seat. The bags are placed on the horizontal bag support platform, and the material sorting push plates on both sides push the bags. During the return process, the synchronous avoidance drive component drives the material sorting push plates on both sides away from each other to avoid bags entering the horizontal bag support platform.

[0009] The material sorting push plate comprises a push plate portion and a side plate portion, wherein the push plate portion is arranged perpendicular to the side plate portion. The side plate portion simultaneously arranges the bags during the pushing process to ensure the bags are neat, and the push plate portion contacts the back side of the bags to push the bags.

[0010] The horizontal bag-carrying platform is equipped with a bag-pressing station, which is equipped with a vertically movable lifting platen located above the platform. The lifting platen can flatten the stacked bags to reduce their volume and perform glue lamination to further ensure bag quality.

[0011] Preferably, the bag input portion includes a conveyor belt, the bag input portion includes a conveyor belt, the bag turnover portion has at least two conveyor belts, and the conveyor belt is arranged between the bag turnover portions. The conveyor belt circulates and drives the bag to move, and the conveyor belt has high transfer efficiency.

[0012] Preferably, the bag turning part is a swing claw, or the bag turning part is a turning bracket, and the turning bracket is cross-shaped. The swing claw swings back and forth to turn the bag, and the turning bracket only needs to rotate in one direction.

[0013] As a preference, a lifting plate is provided above the bag turning part to regularize the upper side of the bag, and the lifting plate is connected to a lifting material driving device that drives it to move up and down. The lifting plate descends to flatten the upper side of the bag to ensure that the bag is neat. Preferably, the clamping arm assembly includes a left clamping arm, a right clamping arm, and a movable frame. The left and right clamping arms are symmetrically movable on the movable frame. The movable frame is connected to a longitudinal drive mechanism. The clamping arm assembly faces the bag bundling section. A pusher block is provided between the left and right clamping arms. The left and right clamping arms partially clamp the bag. The longitudinal drive mechanism drives the clamping arm assembly to carry the bag into the bag bundling section for bundling. During movement, the pusher block flattens the rear side surface, ensuring neat bag stacking and bundling quality.

[0014] On the basis of having a stop gauge, a front stop gauge lifting plate is provided between the movable encircling clamping part and the bag body bundling part, and the front stop gauge lifting plate is slidably arranged on the frame. The front stop gauge lifting plate and the stop gauge cooperate to regularize the front and back sides of the bag body.

[0015] In addition to the bag bundling unit, an auxiliary clamping plate assembly is installed in front of the bag bundling unit to cooperate with the mobile encircling clamping unit to clamp and bundle the materials. When the clamping arm assembly and auxiliary clamping plate assembly are in operation, the clamping areas of the vertical bag are located on both sides of the reserved bundling area. Because when the mobile encircling clamping unit clamps one side of the paper bag, the pressure difference between the stressed and unstressed points on the bag causes the unstressed part to expand outward, causing the bag to bend. The auxiliary clamping arm assembly ensures the flatness of the bag on the other side, facilitating bundling and further ensuring packaging quality.

[0016] The bag packaging device is equipped with a push-stop, and the inlet end of the bag bundling unit is connected to the outlet end of the bag bundling unit. The push-stop is in driving connection with the regular pushing drive component, and the push-stop can push the bundled bags out of the bag bundling unit. The bundled bags enter the bag packaging device, and are wrapped with wrapping paper to protect the bags and facilitate boxing and transportation. The push-stop can move the bags to the next process.

[0017] On the basis of the connection between the bag packaging device and the discharge end of the bag bundling part, the bag packaging device is arranged below the bag bundling part, and a lifting platform is provided between the bag packaging device and the bag bundling part. A first push plate is provided on one side of the lifting platform to push the bag into the bag packaging device, and the first push plate is transmission-connected to a packaging pushing drive device provided on a frame; alternatively, the movable encircling clamping part includes a pushing stop; the bag packaging device is arranged in front of the bag bundling part, and the regular pushing drive component drives the pushing stop to push the bag into the bag packaging device. When the bag packaging device and the bag bundling part are arranged vertically, the pushing stop pushes the bundled bag onto the lifting platform. After the lifting platform descends, the first push plate pushes the bag on the lifting platform into the bag packaging device. When the bag packaging device and the bag bundling part are on the same level, the pushing stop directly pushes the bundled bag into the bag packaging device, resulting in a simple structure and low cost.

[0028] The present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the drawings, the X-axis is the horizontal direction, i.e., the left-right direction; the Y-axis is the longitudinal direction, i.e., the front-back direction; and the Z-axis is the vertical direction, i.e., the up-down direction.

[0029] refer to Figure 1 and Figure 2The paper bag baler is used to pack and package the stacked paper bags, and then use wrapping paper to wrap the packed paper bags. A paper bag baler that integrates vertical stacking and packaging of paper bags includes a frame, on which a bag turning part 2, a bag clamping and transporting part, and a movable embracing clamping part 5 are sequentially provided; the bag turning part 2 is connected between the bag input part for conveying horizontal bags 31 and the vertical bag carrying platform 3, and the bag turning part 2 is rotatably arranged on the frame. The bag input part can convey single or small batches of unit paper bags, but in order to improve efficiency, the unit paper bags are usually conveyed one by one. The bag turning part 2 turns the horizontal bag 31 into a vertical bag 32. To solve the problem that the one-way stacking of square bottom paper bags will cause the stacked bags to tilt to one side, affecting the quality of subsequent packaging, the bag input part is provided with a bag opening turning part for turning the bag opening of the horizontal paper bag alternately forward and reverse. The bag opening turning part turns the bag opening alternately forward or reverse, and the bag input part transports the turned bags to ensure that the integrated bag stack is flat and neat. Figure 5 As shown, the bag-turning portion 2 has a first channel, and the vertical bag-supporting platform 3 has a second channel. The vertical bag-supporting platform 3 has a plurality of supporting rods, which form a supporting surface. The supporting rods are spaced apart, and the gaps between the supporting rods form the second channel. When the bag on the bag-turning portion 2 is a vertical bag 32, the first channel and the second channel are connected to form an integrated channel. In this embodiment, the bag-turning portion 2 is turned inside the second channel. After the bag-turning portion 2 turns the horizontal bag 31 into a vertical bag 32, the vertical bag 32 is directly placed on the vertical bag-supporting platform 3. Horizontal bags 31 can only be stacked upwards, and the number of stacks is limited. If too many are stacked, the height will be too high, which will easily collapse and hinder subsequent bundling and packaging. However, after the bag-turning portion 2 turns the vertical bags 32, stacking them horizontally will only increase their length. In a single stacking package, the number of vertical bags 32 stacked is greater than that of horizontal bags 31, which is beneficial for improving work efficiency. There are many implementation methods of the bag body turning part 2, such as the rotating part being a swing claw (such as Figure 7 and Figure 8 ) or the rotating part is a flip bracket (such as Figure 9 ), the flip bracket is cross-shaped as a whole, which can realize continuous flipping.

[0030] like Figure 5As shown, the bag body clamping and transferring part includes a lifting bag pushing rod group 41 that enters the first channel to push the integrated bag body and a lifting limiting rod group 42 that cooperates with the lifting bag pushing rod group 41 to transfer the bag body. The lifting bag pushing rod group 41 and the lifting limiting rod group 42 are arranged relatively to the left and right of the vertical bag body carrying platform 3. The lifting bag pushing rod group 41 and the lifting limiting rod group 42 can be arranged above or below the vertical bag body carrying platform 3. In this embodiment, the lifting bag pushing rod group 41 and the lifting limiting rod group 42 can be arranged below the vertical bag body carrying platform 3, and the lifting bag pushing rod group 41 and the lifting limiting rod are respectively connected to the lifting driving device. The lifting bag pushing rod group 41 includes a first moving frame, a bag pushing rod and a first lifting driving member, which are lifted and slid up and down on the first moving frame. The first lifting driving member drives the bag pushing rod to move up and down relative to the vertical bag body carrying platform 3. The first lifting driving member drives the bag pushing rod to rise and enter the first channel of the bag body turning part 2, pushing the vertical bag 32 out of the bag body turning part 2. The lifting and limiting rod group 42 includes a second moving frame, a limiting rod and a second lifting drive member. The limiting rod is slidably arranged on the second moving frame. The second lifting drive member drives the limiting rod to move up and down relative to the vertical bag body supporting platform 3. The limiting rod rises to prevent the vertical bag body 32 from collapsing. The lifting bag pushing rod group 41 and the lifting and limiting rod group 42 are respectively connected to the driving device, and the driving device drives the lifting bag pushing rod group 41 and the lifting and limiting rod group 42 to move in the integrated channel. In this embodiment, the driving device includes two power sources, which are respectively connected to the first moving frame and the second moving frame to drive the first moving frame and the second moving frame to move respectively. The driving device drives the bag body clamping and transporting part to reciprocate between the bag body turning part 2 and the vertical bag body supporting platform 3. The driving device can be a linear driving device such as a cylinder or a ball screw.

[0031] like Figure 6As shown, the mobile encircling clamping part 5 is connected with the bag body clamping and transporting part, and the mobile encircling clamping part 5 is arranged behind the bag body clamping and transporting part. The mobile encircling clamping part 5 includes a clamping arm group 51 for clamping a part of the bag body. The clamping arm group 51 of the mobile encircling clamping part 5 has a clamping cavity that can accommodate the bag body. The forward movement of the clamping arm group 51 can make the lifting bag pushing rod group 41 and the lifting limit rod group 42 enter the clamping cavity. The specific clamping arm group 51 includes a left clamping arm, a right clamping arm and a movable frame. The left clamping arm and the right clamping arm can move symmetrically on the movable frame. The movable frame has a slide rail. The left and right clamping arms are slidably arranged on the slide rail. The clamping arm group 51 has a clamping power source. Cylinders are respectively provided on both sides of the movable frame to drive the left and right clamping arms to move symmetrically. The power source can also be a motor. When the clamping arm group 51 is working, the vertical bag body includes a clamping area for clamping and a bundling reserved area for bundling. The clamping arm group 51 clamps the bag body when the bag body clamping and transporting part moves to the handover station, that is, the front part of the bag body is exposed to facilitate subsequent bundling. The clamping arm group 51 is connected to the longitudinal drive mechanism in a transmission manner. The movable frame in the clamping arm group 51 is connected to the longitudinal drive mechanism. The longitudinal drive device is fixedly arranged on the frame. The movable frame is connected to the drive rod of the longitudinal drive device to drive the left and right clamping arms to move back and forth. The clamping arm group 51 is toward the bag body bundling part 6. The clamped bag is moved forward. There is a pusher gauge 52 between the left clamping arm and the right clamping arm. The pusher gauge 52 can regularize the rear side of the bag to ensure that the bag is neatly stacked. The encircling transfer mechanism makes the overall paper bag movement path at a right angle, shortening the length of the overall equipment. How the bag strapping part 6 straps the bag is a conventional technique that is easily known to those skilled in the art. The bag strapping part 6 is arranged in front of the mobile encircling clamping part 5. The bag strapping part 6 continues to strap the reserved strapping area of the bag. The bag strapping and packing are convenient for subsequent packaging and subsequent boxing.

[0032] The working principle of the present invention is as follows: the bag turning section 2 rotates the bag opening of the square-bottom paper bag alternately forward or reverse, and the bag input section alternately delivers the horizontal bag 31 with the bag opening facing forward and the horizontal bag 31 with the bag opening facing reverse to the bag turning section 2. Subsequently, the bag turning section 2 turns 90 degrees around its axis, turning the horizontal bag 31 into a vertical bag 32. The lifting and pushing rod group 41 and the lifting and limiting rod group 42 move to the bottom of the bag turning section 2. The lifting and limiting rod group 42 rises to position the bag to prevent it from collapsing. The bag pushing rod of the lifting and pushing rod group 41 rises and enters the first channel of the bag turning section 2. The lifting and pushing rod group 41 moves to the right. The lifting and pushing rod group 41 and the lifting and limiting rod group 42 cooperate to clamp the bag and move it toward the vertical bag supporting platform 3. After the horizontal bag 31 is flipped into a vertical bag 32, the bag clamping and transporting unit clamps the bag and moves it toward the bag flipping unit 2. Then, the lifting and pushing rod group 41 moves down to avoid it. The lifting and limiting rod group 42 continues to move toward the bag flipping unit 2 in the integration channel to integrate the bags. The lifting and limiting rod group 42 moves into the first channel of the bag flipping unit 2 and rises. In cooperation with the lifting and limiting rod group 42, the integrated bag stack is transferred to the transfer station. The number of integrations can be adjusted according to the number of bags packaged.

[0033] The longitudinal drive mechanism drives the clamping arm group 51 forward, allowing the lifting and pushing bag rod group 41 and the lifting and limiting rod group 42 to enter the clamping cavity. Then, the lifting and pushing bag rod group 41 and the lifting and limiting rod group 42 descend to release the bag stack for easy reception by the clamping arm group 51. The clamping arm group 51 clamps the clamping area of the bag stack and carries the bag stack forward, using the bag bundling part to bundle the reserved area of the bag stack. The bags are flipped from horizontal to vertical for collection. Compared with conventional horizontal paper bag stacking and packaging, more bags can be packaged and the structure is more reasonable. After the bags are collected and integrated, they are all moved by clamping to reduce the volume of the bag stack. The compact bag stack can improve the space utilization rate of subsequent packaging.

[0034] There are many implementation methods for the bag mouth steering part, such as the bag mouth steering part being a manipulator, which is placed on the bag body input part after steering the bag body, or the bag mouth steering part including a rotating turntable 81 and a rotating pressure block that cooperates with the turntable 81 to steer the bag body, the turntable 81 is connected to the rotating power source, and the rotating power source drives the turntable 81 to rotate alternately in forward and reverse directions, so that the bag mouth of the bag body rotates alternately to the left and right in turn to ensure that the subsequent stacked bag body is flat as a whole, which is convenient for subsequent packaging. The rotating pressure block is connected to the lifting power source, and the rotating pressure block descends and cooperates with the turntable 81 to clamp and rotate the bag body. For unit bags, it can prevent the bag body from flying out due to inertia. In addition, in order to prevent the bottom bag body from wearing out during the rotation process, the turntable 81 can be raised and lowered.

[0035] In order to make the bag conveying smoother, the bearing surface of the bag input part is not lower than the feeding end surface of the bag turning part 2. There are many implementation methods of the bag input part, such as Figure 3 As shown, the bag input part includes a horizontal bag supporting platform 1 and a material sorting push plate 12. The material bearing surface of the horizontal bag supporting platform 1 is not lower than the feeding end surface of the bag turning part 2, so that the conveying is smoother. The material sorting push plates 12 are arranged on both sides of the horizontal bag supporting platform 1, and the material sorting push plates 12 are arranged on the moving seat 11. A single set of push plates can be arranged on the moving seat 11, or multiple sets of material sorting push plates 12 can be arranged to improve the bag conveying efficiency. A pushing track is arranged horizontally and parallel on the frame, and the moving seat 11 is slidably arranged on the pushing track. The moving seat 11 is connected to the bag input driving component that drives it to move left and right. The bag input driving component can be a belt driving device or a screw driving device that drives the moving seat 11 to move left and right; the material sorting push plate 12 is also connected to the avoidance driving component that drives it to move forward and backward. The avoidance driving component makes the material sorting push plates 12 on both sides move symmetrically back and forth. The specific avoidance driving component can be arranged on the moving seat 11 and the material sorting push plate 12. A guide rod 111 is provided between the material pushing plates 12, or between the movable seats 11 on both sides. The guide rod 111 has a fixed plate 14 and a movable mounting plate 13. Multiple groups or a single group of material pushing plates 12 are fixedly set on the movable mounting plate 13. The fixed plate 14 is between the movable seat 11 and the movable mounting plate 13. The fixed plate 14 is fixedly set on the guide rod 111. The movable mounting plate 13 is slidably set on the guide rod 111. The avoidance driving component is set on the fixed plate 14 to drive the movable mounting plate 13 to move back and forth on the guide rod 111.

[0036] In order to ensure the quality of the bag stack packaging, the material sorting push plate 12 includes a push plate portion 122 and a side plate portion 121, and the push plate portion 122 is arranged perpendicular to the side plate portion 121. When the avoidance driving component drives the material sorting push plates 12 on both sides to be relatively close, the side plate portion 121 of the material sorting push plate 12 can regularize the two sides of the bag body to ensure the quality of subsequent packaging. The push plate portion 122 pushes the bag body, and the push plate portion 122 and the side plate portion 121 are arranged perpendicularly to facilitate regularization of the bag body. In order for the horizontal bag body supporting platform 1 to have a bag pressing station, the bag pressing station is equipped with a lifting and lowering pressure plate 9 that can move up and down, and the lifting and lowering pressure plate 9 is arranged above the horizontal bag body supporting platform 1. In order to ensure the flatness of the bag body, reduce the volume of the bag body and facilitate subsequent processing operations, the horizontal bag body supporting platform 1 has a bag pressing station, and the bag pressing station is equipped with a lifting pressure plate 9 that can move up and down. The lifting pressure plate 9 is connected to the cylinder. The lifting pressure plate 9 is arranged above the horizontal bag body supporting platform 1. The lifting pressure plate 9 descends to compact the bag body and can also glue the bag body to ensure product quality.

[0037] Another embodiment of the bag body input part, the bag body input part includes a conveyor belt, the conveyor belt is arranged in a ring, the bag body turning part 2 has at least two, the conveyor belt is arranged between the bag body turning part 2, the conveying plane of the conveyor belt is not lower than the feeding end face of the bag body turning part 2, which can ensure that all the bags enter the bag body turning part 2. When the bag mouth turning part is a robot, the robot can directly place the turned bag on the conveyor belt. When the bag mouth turning part is a turntable 81, the conveyor belt can be arranged on both sides of the turntable 81.

[0038] In order to further ensure the neatness of the bag body, a lifting and patting plate 10 for regularizing the upper side of the bag body is provided above the bag body turning part 2. The lifting and patting plate 10 is connected to the lifting and sorting driving device that drives it to move up and down. The lifting and sorting driving device drives the lifting and patting plate 1010 to descend, flattening the upper side of the bag body, further ensuring the packaging quality of subsequent bags.

[0039] To further ensure neat stacking of the assembled bags, in addition to the pusher block 52, a front block lift plate 40 is installed between the movable encircling clamping portion 5 and the bag bundling portion 6. The front block lift plate 40 is mounted on the frame and slides up and down. The left and right clamping arms grip the bag and deliver it forward, bringing the front side of the bag into contact with the front block lift plate 40. The pusher block 52 cooperates to straighten the back side of the bag, ensuring neat stacking when bundling.

[0040] When the mobile encircling clamping part 5 clamps a part of the bag body, the pressure difference between the stressed point and the unstressed point on the bag body will cause the unstressed part to expand outward, causing the paper bag to bend. In order to ensure the quality of the bag body and the subsequent bundling effect, an auxiliary splint group 10 is provided in front of the bag body bundling part 6 to cooperate with the mobile encircling clamping part 5 to clamp and bundle the materials. The auxiliary splint group 10 includes a left auxiliary splint 201 and a right auxiliary splint 202. The left auxiliary splint 201 and the right auxiliary splint 202 can move symmetrically. The left auxiliary splint 201 and the right auxiliary splint 202 are slidably set on the frame, and the two are respectively connected to a power source to drive their relative movement. When the clamping arm group and the auxiliary splint group are working, the clamping area of the vertical bag body is set on both sides of the bundling reserved area. The movable encircling clamping unit 5 partially clamps the bag, while the auxiliary clamping arm assembly clamps the other side of the bag. A gap exists between the two. This gap leaves an unclamped portion of the bag (i.e., a reserved area for bundling) for the bag bundling unit 6 to perform bundling. Furthermore, the movable encircling clamping unit 5 and the auxiliary clamping arm assembly 20 each clamp the bag, compressing the bag and reducing its volume. This facilitates subsequent packaging and transportation, improving space utilization.

[0041] In order to protect the bag and facilitate subsequent transportation of the bag, the feeding end of the bag packaging device 7 is connected to the discharging end of the bag bundling part 6, and the pushing stop 52 is connected to the regular pushing driving component that drives it to move back and forth. The pushing stop 52 can push the bundled bag out of the bag bundling part 6. The bag packaging device 7 is a prior art, which includes a paper feeding mechanism, a pressing mechanism, a folding mechanism and a finished product output mechanism; the pushing gauge 52 pushes the bag into the paper feeding mechanism, and the cutting component of the paper feeding mechanism cuts the packaging paper into the required specifications, and then the two enter the pressing mechanism. The pressing mechanism folds the front end of the packaging paper backward and the rear end of the packaging paper forward to wrap the packaging paper. At this time, the packaging paper is a flat rectangular parallelepiped, similar to the shape of the stacked bags, and the two sides of the packaging paper are longer than the bag body. After pressing, the edges are folded, and the ears are folded before folding. The front end of the packaging paper is folded backward along the vertical edge of the bag body, and the rear end of the packaging paper is folded forward along the vertical edge of the other end of the bag body, and then the upper end of the packaging paper is folded downward and the lower end is folded upward to completely wrap the large paper and send it out after packaging is completed.

[0042] There are many ways to connect the bag packaging device 7 with the bag bundling part 6. For example, the bag packaging device 7 is arranged below the bag bundling part 6, and a lifting platform is provided between the bag packaging device 7 and the bag bundling part 6. One side of the lifting platform is provided with a first push plate for pushing the bag into the bag packaging device 7. The first push plate is transmission-connected with the packaging pushing drive device provided on the frame. After the bag is bundled, it is sent to the lifting platform by the pushing gauge 52. The lifting platform carries the bag down to the front of the first push plate. The packaging pushing drive device drives the first push plate to push the bag into the bag packaging device 7. While pushing in, the bag enters the packaging paper. There is a rubber strip on the side of the packaging paper. The pressing mechanism causes the packaging paper to package the main body of the bag stack into a flat rectangular parallelepiped. Then the folding mechanism folds the ears and folds the edges of the packaging paper. The packaged bag is convenient for transportation, and the packaging paper can provide protection for the bag. Alternatively, the conveying path of the bag packaging device 7 is on the same horizontal plane as the conveying path of the movable embracing clamping part 5, that is, the bag packaging device 7 is arranged in front of the bag bundling part 6, and the regular pushing driving component drives the pushing gauge 52 to push the bag into the bag packaging device 7 for the above-mentioned packaging. The multifunctional performance of the pushing gauge 52 reduces costs and has a simple structure.
