Description

Technical Field

[0001] The invention relates to the technical field of woven bag production, and in particular discloses a finished woven bag packaging device. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. In order to facilitate the stacking and transportation of woven bags, they need to be stacked and packed into a whole after production is completed; conventional woven bags are woven and have a certain degree of air permeability, so they can be directly squeezed downward when packing to reduce their volume before bundling. However, some packaging used in agricultural and industrial fields needs to have waterproof properties, such as the packaging of seeds, fertilizers or chemical raw materials. Therefore, it is necessary to add an inner film inside the conventional woven bag, which is usually called a waterproof woven bag.

[0003] For example, the patent with announcement number CN110606231B, with announcement date of September 21, 2021, discloses a woven bag packing device, comprising a clamping slider horizontally slidably arranged on a frame, and an upper clamping jaw and a lower clamping jaw are arranged on the clamping slider, and the upper clamping jaw and the lower clamping jaw can approach and move away from each other, and the upper clamping jaw and the lower clamping jaw each include at least two parallel cantilever claws, and the cantilever claws are parallel to the sliding direction of the clamping jaw slider; a woven bag support is arranged in the direction pointed by the cantilever claws, and the height of the woven bag support satisfies that the upper clamping jaw and the lower clamping jaw can clamp the stacked woven bags and then move them laterally to the woven bag support without interfering with the cantilever claws; a clamping mechanism is arranged above the woven bag support, and the clamping mechanism descends and can press on the woven bag from the position between the cantilever claws adjacent to the upper clamping jaw, and an annular packing belt is arranged around the moving trajectory of the woven bag above the woven bag support.

[0004] The disadvantage of the existing packaging devices including the above-mentioned patent is that the stacked woven bags are directly squeezed downwards during packaging, and the waterproof woven belt can only exhaust gas outwards on one side of the bag opening. When it is squeezed downwards, part of the gas cannot be discharged in the inner membrane, which may cause the inner membrane to be damaged due to bloating. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] In the description of the present invention, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-Figure 9 As shown, a finished woven bag packaging device provided by an embodiment of the present invention includes a casing 1, wherein an extrusion plate 2 and a supporting plate 3 are arranged opposite to each other in the upper and lower parts of the casing 1, and a driving member capable of driving the extrusion plate 2 to move toward the supporting plate 3 is also arranged in the casing 1. The extrusion plate 2 is driven to move toward the supporting plate 3 and is adjusted from an inclined posture to a horizontal posture to realize the exhaust and compression of the woven bags stacked on the supporting plate 3.

[0033] Specifically, the housing 1 is the main structure of the packaging device, and a horizontal channel is arranged inside the housing, and the two ends of the channel are the feeding end and the discharging end respectively. Figure 2 In the view, the left side is the discharge end of the channel, and the right side is the feed end of the channel. An extrusion plate 2 and a bearing plate 3 are arranged inside the housing 1. The extrusion plate 2 and the bearing plate 3 are both rectangular plates, wherein the extrusion plate 2 is arranged directly above the bearing plate 3. A clearance groove 31 is opened on the bearing plate 3 along the width direction of the housing 1. Figure 2The horizontal direction is the length direction of the casing 1, the vertical direction is the height direction of the casing 1, and the direction perpendicular to the horizontal and vertical directions is the width direction of the casing 1, so that a part of the bottom of the woven bag can be exposed for bundling, and a driving member for driving the extrusion plate 2 to move toward the carrier plate 3 is also provided in the casing 1, and the driving member is an existing linear driving mechanism such as a hydraulic cylinder; what is different from the prior art is that in the process of the extrusion plate 2 being driven to move toward the carrier plate 3, in the initial stage of the extrusion plate 2 moving downward, it is in an inclined posture such as 5-10 degrees, and the side close to the bottom of the woven bag is its lowest side, and when the extrusion plate 2 moves downward During the process, this side preferentially contacts with the corresponding position on the woven bag (the side of the woven bag close to the bottom of the bag). When the extrusion plate 2 approaches the end of its stroke, that is, when the woven bag is about to reach the maximum compression, the extrusion plate 2 gradually adjusts from an inclined posture to a horizontal posture, and squeezes and discharges the air inside the woven bag from the bottom of the bag to the bag mouth. In the whole process of the extrusion plate 2 moving downward, the compression and exhaust of the woven bag are not prioritized. Obviously, the loading of the woven bag can be done manually or by setting a loading mechanism in the casing 1. It is an existing technology to use a loading mechanism to transfer the stacked woven bags from the conveyor to the supporting plate 3, which can be directly applied without further elaboration.

[0034] The packaging device provided in an embodiment of the present invention enables the extrusion plate 2 to have an inclined posture and a horizontal posture, and gradually adjusts it from an inclined posture to a horizontal posture during the downward movement of the extrusion plate 2. The air in the woven bag is guided to the bag opening through the inclined plate surface of the extrusion plate 2, thereby achieving maximum compression of the woven belt without damaging the inner membrane.

[0035] Furthermore, the driving member is at least two groups of linear drivers rotatably installed in the housing 1 , each linear driver is arranged in parallel along the length direction of the extrusion plate 2 , and each linear driver is rotatably connected to the extrusion plate 2 .

[0036] Specifically, since the extrusion plate 2 needs to be adjusted from an inclined posture to a horizontal posture during the downward movement, that is, the driving member needs to drive the extrusion plate 2 to move downward and rotate. In this embodiment, the driving member is a linear driver (such as any one of a cylinder, an electric push rod and a hydraulic cylinder). Figures 2 to 4 As shown, the upper end of each linear actuator, i.e., the fixed end, is rotatably mounted on the top of the housing 1, and the lower end of each linear actuator, i.e., the output end, is rotatably connected to the extrusion plate 2. Figure 2 The linear actuators shown in FIG. 1 are two groups, and the two linear actuators are arranged along the length direction of the extrusion plate 2, that is, Figure 2 The horizontal direction shown is staggered; in specific implementation, the state of the extrusion plate 2 can be adjusted by the different extension amounts of the two linear drives. When the extension amounts of the two linear drives are consistent, the extrusion plate 2 is in a horizontal posture, and when the extension amounts of the two linear drives are different, the extrusion plate 2 is in an inclined posture.

[0037] In another embodiment provided by the present invention, a first extrusion block 4 is provided on one side of the extrusion plate 2 in the casing 1, and a slot 41 is provided on the lower end surface of the first extrusion block 4 along its width direction. The first extrusion block 4 is driven to move downward synchronously with the lowest side of the extrusion plate 2.

[0038] Specifically, in the actual production process, in order to improve the waterproof, UV-resistant, and aging-resistant properties of the woven bag, although a waterproof film is provided inside the woven bag, it is still necessary to coat the outside of the woven bag with a waterproof material (polyurethane or acrylic coating). In the above embodiment, in the early stage of squeezing the woven bag, the squeezing plate 2 squeezes the woven bag in an inclined posture, and the squeezing force of the squeezing plate 2 on the woven bag has a component force in the horizontal direction. When the surface of the woven bag is coated with waterproof material, the friction between the upper and lower layers of the woven bag is insufficient to maintain relative stillness, resulting in the stacking cross-section of the woven bag gradually changing from a rectangle to a diamond during the squeezing process, which is not convenient for bundling. In this embodiment, a first squeezing block 4 is also provided in the casing 1, such as Figure 2 As shown, the first extrusion block 4 is arranged along the width direction of the casing 1, and another linear driver is further arranged in the casing 1 corresponding to the extrusion plate 2. The fixed end of the linear driver is fixedly connected to the top of the casing 1, and the first extrusion block 4 is fixedly connected to the lower end, i.e., the output end, of the linear driver, and the lower end surface of the first extrusion block 4 is provided with a slot 41 along its own width direction, i.e., the length direction of the casing 1, and the woven bag is also placed along the length direction of the casing 1; when the extrusion plate 2 is driven to move downward, the first extrusion block 4 is driven to move downward synchronously with the lower side of the extrusion plate 2. In the above embodiment, the lower side of the extrusion plate 2 corresponds to the woven bag The bottom of the woven bag and the first extrusion block 4 correspond to the side where the bag opening of the woven bag is located. This arrangement allows the woven bag to be squeezed, and its bag opening and both sides of the bag bottom are squeezed by the first extrusion block 4 and the lower side of the extrusion plate 2 respectively, and thus deform to a greater extent, while the middle part of the woven bag is squeezed less, and thus the deformation is smaller. At this time, the stacked woven bags will appear in a state of arching in the middle, which can prevent the woven bags from sliding in the horizontal direction. The notch 41 opened on the first extrusion block 4 prevents the bag opening from being squeezed and completely blocked, thereby ensuring that the air in the inner film can be smoothly discharged from the side where the bag opening is located.

[0039] Furthermore, a second extrusion block 5 is rotatably connected to a side of the extrusion plate 2 away from the first extrusion block 4 , and the second extrusion block 5 is driven to move downward synchronously with the first extrusion block 4 .

[0040] Specifically, in the above embodiment, since the extrusion plate 2 moves downward in an inclined posture at the initial stage of extruding the woven bag, the contact between the lower side of the extrusion plate 2 and the woven bag is close to line contact, which results in that the side where the bottom of the woven bag is located is less restricted, and the line contact is more likely to damage the top layer of the woven bag; in this embodiment, the second extrusion block 5 is rotatably installed on the side of the extrusion plate 2 away from the first extrusion block 4, such as Figures 2 to 4 As shown in the figure, the first extrusion block 4 is located on the left side of the extrusion plate 2, and the second extrusion block 5 is located on the right side of the extrusion plate 2. Another linear actuator is also fixedly connected to the top of the housing 1. The installation method of the linear actuator is the same as that of the linear actuator corresponding to the first extrusion block 4. The second extrusion block 5 is fixedly connected to the lower end of the linear actuator.

[0041] For ease of description, the two groups of linear actuators corresponding to the extrusion plate 2 are respectively the first actuator 11 and the second actuator 12, the linear actuator corresponding to the first extrusion block 4 is the third actuator 13, and the linear actuator corresponding to the second extrusion block 5 is the fourth actuator 14, wherein the first actuator 11 is installed on the side of the casing 1 close to the third actuator 13, and the second actuator 12 is installed on the side of the casing 1 close to the fourth actuator 14; in the early stage of extruding the woven bag, the third actuator 13 and the fourth actuator 14 have the same expansion and contraction amount, so as to keep the first extrusion block 4 and the second extrusion block 5 moving down synchronously and always at the same height. degree, and the elongation of the first driver 11, the second driver 12 and the third driver 13 gradually increases. In this way, the first extrusion block 4 and the second extrusion block 5 can first contact the woven bag. With the synchronous elongation of each linear driver, when the two ends of the woven bag, that is, the bag opening side and the bag bottom side, reach the set compression amount, the first driver 11 and the second driver 12 continue to extend. At this time, the expansion and contraction speed of the first driver 11 is greater than the expansion and contraction speed of the second driver 12, until the extrusion plate 2 rotates to a horizontal state with its hinge axis with the second extrusion block 5 as the central axis. At this stage, the air in the woven bag can be gradually squeezed toward the bag opening side.

[0042] In this embodiment, a second extrusion block 5 is added and a fourth driver 14 is correspondingly arranged thereto so that the second extrusion block 5 can be moved downward synchronously with the first extrusion block 4, thereby enhancing the limiting effect on the bottom side of the woven bag and further preventing the woven bag from being displaced in the horizontal direction.

[0043] Furthermore, a vertically arranged movable plate 42 is slidably mounted on a side of the first extrusion block 4 away from the extrusion plate 2 , and a vertical slot 421 is formed on the movable plate 42 .

[0044] Specifically, in the above embodiment, the extrusion plate 2 can be divided into a first stroke and a second stroke, wherein in the first stroke, the extrusion plate 2 moves down in an inclined state, and in the second stroke, the extrusion plate 2 gradually rotates from the inclined state to the horizontal state. Although the first extrusion block 4 and the second extrusion block 5 respectively squeeze and limit the bag opening side and the bag bottom side of the woven bag, in the first stroke of the extrusion plate 2, the stacked woven bags are gradually squeezed and contracted, and the extrusion force on the woven bags in the first stroke is in an increasing state. In order to further avoid horizontal displacement of the woven bags, in this embodiment, the first extrusion block 4 is away from the side of the extrusion plate 2, that is, Figure 2 A movable plate 42 is provided on the left side of the view, and the movable plate 42 is slidably connected to the first extrusion block 4, and the movable plate 42 slides along the height direction of the housing 1; in this way, when the woven bag is extruded, the lower end of the movable plate 42 can directly contact the bearing plate 3 and block the woven bag at Figure 2 On the left side of the view, as the first extrusion block 4 moves downward, the movable plate 42 slides relative to the first extrusion plate 2 because the lower end is blocked by the supporting plate 3; to prevent the exhaust of the woven bag from being blocked, a vertical groove 421 is opened on the movable plate 42, and the vertical groove 421 is opened on one side surface of the movable plate 42 corresponding to the extrusion plate 2, and the vertical grooves 421 are all opened along the height direction of the casing 1.

[0045] In another embodiment of the present invention, a bundling assembly 6 is further disposed in the housing 1 .

[0046] Specifically, in order to further improve the packaging efficiency, a strapping assembly 6 is further provided in the housing 1. The strapping assembly 6 is an existing automatic strapping machine. The strapping assembly 6 is provided with at least two groups. Since the extrusion plate 2 is an integral plate, in order to facilitate the smooth withdrawal of the extrusion plate 2 after the strapping is completed, the strapping mechanism is provided with two groups. The two strapping mechanisms are respectively provided corresponding to the bag mouth side and the bag bottom side of the woven bag, that is, Figure 2 In the view, on the left side of the extrusion plate 2 and the right side of the second extrusion block 5, two groups of strapping components 6 strap the bag opening side and the bag bottom side of the stacked woven bags respectively.

[0047] Furthermore, the extrusion plate 2 includes a first plate 21 and a second plate 22, and the first plate 21 and the second extrusion block 5 are both rotatably connected with a giveway plate 23, and the hinge shafts of the giveway plate 23 and the first plate 21 and the second extrusion block 5 are provided with torsion springs. When the torsion springs are in a natural state, the giveway plate 23 is in an inclined state, and the positions of the second plate 22 corresponding to the giveway plates 23 are provided with locking members, and the locking members lock the corresponding giveway plates 23 so that the first plate 21, the second plate 22 and the second extrusion block 5 can be a whole.

[0048] Specifically, in the above embodiment, since the extrusion plate 2 is a whole plate, and the extrusion plate 2 and the second extrusion block 5 are hinged to each other, the two groups of strapping components 6 can only be arranged on both sides of the extrusion plate 2 and the second extrusion block 5 as a whole, that is, one group of strapping components 6 is arranged at the gap between the first extrusion block 4 and the extrusion plate 2, and the other group of strapping components 6 is arranged on the side of the second extrusion block 5 away from the extrusion plate 2, so that only the bag opening side and the bag bottom side of the woven bag are strapped. When the woven bag cannot be squeezed to the maximum extent, the extrusion plate 2, the first extrusion block 4, the second extrusion block 5 and the woven bag are separated. After the woven bag is separated, the middle part of the woven bag will be inflated due to the inflation, which may easily cause the strapping belt on the bag mouth side or the bag bottom side to fall off. Assuming that the strapping position of the strapping assembly 6 corresponding to the first extrusion block 4 is the first strapping position, and the strapping position of the strapping assembly 6 corresponding to the second extrusion block 5 is the second strapping position, then only the left side of the second strapping position on the woven bag is squeezed by the second extrusion block 5, and the second strapping position will be more likely to cause the strapping belt to fall off due to loose strapping; in this embodiment, the extrusion plate 2 includes a first plate 21, a second plate 22 and two sets of give way plates 23, wherein the first plate 21 is connected to the above-mentioned first driver 11 The second plate 22 is connected to the second driver 12, and a yield plate 23 is rotatably connected to one side of the first plate 21 corresponding to the second plate 22, and the other yield plate 23 is rotatably connected to the second extrusion block 5, and a torsion spring is provided at the rotation axis of the two yield plates 23. When the torsion spring is in a natural state, the yield plate 23 corresponding to the torsion spring is in an inclined state. Preferably, the inclination angle of the yield plate 23 is greater than 70 degrees, so as to make enough space for bundling; in addition, a locking piece is provided on the second plate 22 corresponding to the yield plate 23, and the locking piece is used to lock the corresponding yield plate 23, so that The plate surfaces of the first plate 21, the second plate 22 and the two give-way plates 23 can be in the same plane, so that the first plate 21, the second plate 22 and the two give-way plates 23 can constitute a whole plate body, so as to facilitate the control of the inclination angle of the extrusion plate 2 to ensure the extrusion and exhaust effects; the locking piece can adopt magnetic locking technology, which is a prior art and can be directly applied without further elaboration; in addition, in the present embodiment, three groups of strapping components 6 are provided, one group of strapping components 6 corresponds to the gap between the first plate 21 and the first extrusion block 4, and the other two groups of strapping components 6 are respectively provided corresponding to one group of give-way plates 23.

[0049] In this embodiment, the extrusion plate 2 is divided into a first plate 21, a second plate 22 and two give-way plates 23, and the two give-way plates 23 are rotatably connected to the first plate 21 and the second extrusion block 5 respectively. During the extrusion of the woven bag, the give-way plates 23 are restricted by the locking member, so that the first plate 21, the second plate 22 and the two give-way plates 23 can constitute a whole plate member. When the extrusion is completed and bundling is required, the locking member releases the lock of the give-way plates 23, and the give-way plates 23 are driven by the torsion spring to rotate to an inclined state, leaving enough space for bundling straps, so that the middle part of the woven bag can also be bundled, and because a group of give-way plates 23 are arranged between the second plate 22 and the second extrusion plate 2, both sides of the bundling position corresponding to the bundling give-way plates 23 are in a squeezed state, which can ensure that each bundling position can be firmly bundled; on the other hand, the give-way plates 23 between the second plate 22 and the second extrusion block 5 are the hinged hubs of the extrusion plate 2 and the second extrusion block 5, so that the extrusion plate 2 can move downward synchronously with the second extrusion block 5.

[0050] Furthermore, the locking member includes a piston block 221 disposed in the second plate 22, a plug rod 222 is fixedly connected to the piston block 221, each of the yield plates 23 is provided with a socket 231 matching with the plug rod 222, and a piston cavity 223 for installing the piston block 221 is opened on the second plate 22.

[0051] Specifically, Figure 5As shown, in the above embodiment, the give-way block is locked by magnetic attraction. However, in the process of squeezing the woven bag, sufficient squeezing force is required to compress the woven bag as much as possible. It is easy to release the lock of the give-way plate 23 in advance due to excessive shear force on the magnetic attraction position. In the process of compressing the woven bag, once the give-way plate 23 is rotated in advance (normally, it is necessary to wait for the squeezing plate 2 to rotate to a horizontal state as a whole before unlocking), the air inside the woven bag cannot be discharged, but will be concentrated at the position of the give-way plate 23. In the later stage of the compression of the woven bag, the inner membrane will still be damaged due to flatulence. In this embodiment, a piston cavity 223 is provided in the second plate 22 corresponding to the give-way plate 23, and a piston block 221 is slidably installed in the piston cavity 223. When the squeezing plate 2 is in a horizontal state as a whole, the piston block 221 slides in the horizontal direction, that is, the length direction of the casing 1. The piston block 221 is fixed with an insertion rod 222, and the insertion rod 222 penetrates the second plate 22. The outside of the second plate 22 corresponds to the give way plate 23. The give way plate 23 is provided with a socket 231 that matches the plug rod 222. Each piston chamber 223 is connected to an air pump through a pipeline. The air pump is used to inflate the piston chamber 223 so that the piston block 221 slides and the plug rod 222 is plugged into the corresponding socket 231, thereby locking the give way plate 23. Obviously, in order to facilitate the resetting of the piston block 221, each piston chamber 223 on the second plate 22 is provided with a first spring 224. The first spring 224 is sleeved on the outside of the corresponding plug rod 222, and when the first spring 224 is in a natural state, the corresponding plug rod 222 is retracted into the second plate 22. When the plug rod 222 is plugged into the corresponding socket 231, the first spring 224 is in a compressed state. In the process of unlocking the give way plate 23, the first spring 224 can assist the piston block 221 to slide so that the plug rod 222 is retracted into the second plate 22 driven by the piston block 221.

[0052] Furthermore, the piston chamber 223 in the second plate 22 is connected through a small hole 225, and an air plug 7 is slidably installed on the second rod. A first hole 71 is provided at the lower part of the air plug 7, and a second hole 72 is provided at the upper part of the air plug 7. The second hole 72 connects the first hole 71 with the outside. An annular groove 73 is provided at the middle part of the air plug 7 along its own circumference. A second spring 74 is mounted on the outside of the air plug 7 to maintain the relative position of the air plug 7 and the second plate 22, and a pull rope 75 is fixed to the air plug 7.

[0053] Specifically, a gas plug 7 is slidably mounted on the second plate 22, and the cross section of the gas plug 7 is T-shaped. Figure 6 and Figure 7As shown, the gas plug 7 slides along its own axial direction on the second plate 22, an annular groove 73 is provided in the middle of the gas plug 7 along its own circumference, a first hole 71 is provided in the lower part of the gas plug 7, and a second hole 72 is provided in the middle of the gas plug 7 to connect the first hole 71 with the outside, and the two piston chambers 223 in the second plate 22 are connected through the small hole 225; in the sliding stroke of the gas plug 7, the gas plug 7 has a first position and a second position relative to the second plate 22:

[0054] When in the first position, the annular groove 73 is connected to the first hole 71. In this way, only one set of pipelines is provided, and the pipeline is connected to any piston chamber 223 to achieve the driving of the two sets of piston blocks 221.

[0055] When in the second position, the first hole 71 is connected to the small hole 225, so that the air in the two piston chambers 223 can be discharged outward through the small hole 225, the first hole 71 and the second hole 72, so that the first spring 224 can push the piston block 221 to slide in the piston chamber 223 where it is located, thereby moving the insertion rod 222 into the second plate 22.

[0056] The gas plug 7 is provided with a second spring 74, which maintains the relative position between the gas plug 7 and the second plate 22. Figure 6 and Figure 7 As shown, the upper end of the second spring 74 is fixedly connected to the gas plug 7, and the lower end of the second spring 74 is connected to the surface of the second plate 22. When the second spring 74 is in a natural state, the gas plug 7 remains in the first position. In specific implementation, the end of the pull rope 75 away from the gas plug 7 can be fixed. Figures 2 to 4 In the process, the end of the pull rope 75 away from the air plug 7 is fixed to the fixed end of the second driver 12. During the compression of the woven bag, the pull rope 75 is gradually tightened. When the extrusion plate 2 is driven to rotate to a horizontal state, the pull rope 75 pulls the air plug 7 to adjust the air plug 7 from the first position to the second position, thereby passively releasing the lock on the yield plate 23.

[0057] Furthermore, a baffle 15 is provided in the housing 1 above the extrusion plate 2 , and through grooves are provided in the baffle 15 at positions corresponding to the linear drive and the strapping assembly 6 .

[0058] Specifically, in order to facilitate the adjustment of the clearance plate 23 from the inclined state to the horizontal state, in this embodiment, Figures 2 to 4As shown, a baffle 15 is fixedly connected to the housing 1, and the baffle 15 is arranged just above the extrusion plate 2, and a through groove is opened on the baffle 15 to facilitate the installation of the first driver 11, the second driver 12, the third driver 13, the fourth driver 14 and each bundling assembly 6; in this way, after the compression of the woven bag is completed, the first driver 11, the second driver 12, the third driver 13 and the fourth driver 14 respectively drive the first plate 21, the second plate 22, the first extrusion block 4 and the second extrusion block 5 to move up, because the first plate 21 is hinged to the output end of the first driver 11, and the second plate 22 is hinged to the output end of the second driver 12 Then, there will be inclination during the upward movement, and when the first plate 21 and the second plate 22 come into contact with the baffle 15, they will be blocked by the baffle 15 and will gradually rotate to a horizontal state. Similarly, the two give-way plates 23 will also gradually rotate to a horizontal state under the blockage of the baffle 15. When the first plate 21, the second plate 22 and the two give-way plates 23 are all rotated to a horizontal state, the air pump inflates each piston cavity 223, so that the piston block 221 slides in the piston cavity 223 and inserts the insertion rod 222 into the socket 231 on the corresponding give-way plate 23, thereby connecting the first plate 21, the second plate 22 and the second extrusion block 5 into a whole.

[0059] In another embodiment provided by the present invention, a winding mechanism 8 is provided on one side of the housing 1, and the winding mechanism 8 is used to wrap a film around the outside of the woven bag after bundling.

[0060] Specifically, in the actual production process, in order to prevent the bundled woven bags from being contaminated with mud and abrasion during transportation, in this embodiment, a winding mechanism 8 is provided on one side of the casing 1. The winding mechanism 8 is an existing automatic film winding machine. This is a prior art and can be directly applied without further description. The winding mechanism 8 is provided at the outlet end of the channel in the casing 1, that is, Figures 2 to 4 On the left side of the view, the woven bag after bundling is transferred to the turntable of the winding mechanism 8, and then the film winding can be carried out.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
