[0064] Example 1

[0065] like Figure 1 As shown, a versatile paper bag packaging device is provided, including: a support frame 1, a conveyor belt 3, and a paper folding mechanism 2.

[0066] The support frame 1 is the basic structure of the entire equipment, used to support and fix other components. It is covered with a sheet metal shell and connected by screws to protect the entire paper bag packaging equipment.

[0067] The support frame 1 includes an inner lining support frame 12 and an outer lining support frame 11. The lower end of the outer lining support frame 11 is fixedly installed. The inner lining support frame 12 is connected to the outer lining support frame 11 through a lifting device. The lifting device allows the inner lining support frame 12 to move up and down relative to the outer lining support frame 11.

[0068] The conveyor belt 3 is located on one side of the outer liner support frame 11, and the conveyor belt 3 holds the paper bag 101 in packaging, the paper bag 100 to be packaged, and the packaged paper bag; the conveyor belt 3 adopts a common production structure, the paper bag 100 to be packaged is input into the conveyor belt 3, and the packaged paper bag is output.

[0069] The paper folding mechanism 2 is fixedly connected with the inner liner support frame 12, and is arranged above the conveying belt 3 and applies a force to the paper bag 100 to be packaged. The paper folding mechanism 2 moves up and down with the inner liner support frame 12 and changes the shape of the paper bag through physical contact.

[0070] The paper folding mechanism 2 is a key component, and the structure of the paper folding mechanism 2 is described.

[0071] The paper folding mechanism 2 comprises a transverse sliding assembly and a paper folding assembly, the transverse sliding assembly comprises a first sliding end and a second sliding end, the first sliding end and the second sliding end slide towards each other or away from each other, and the sliding direction is the same as the conveying direction of the conveying belt 3; and the two paper folding assemblies are fixedly connected with the first sliding end and the second sliding end through connecting shafts.

[0072] The first sliding end and the second sliding end can move towards each other (slide towards each other) or away from each other (slide away from each other), so as to change the distance between the two paper folding assemblies, so that the entire paper folding mechanism 2 can adapt to paper bags of different widths.

[0073] Each paper folding assembly is responsible for the folding operation of one side of the paper bag, and through the synchronous movement of the two paper folding assemblies, the folding of the opening of the paper bag is realized.

[0074] The paper folding assembly comprises a shell surface 21, a longitudinal sliding assembly, a rotating assembly, a rotating shaft 23 and a clamping plate 22.

[0075] The shell surface 21 is fixedly connected with the connecting shaft and serves as a fixed support structure of the entire paper folding assembly.

[0076] The longitudinal sliding assembly comprises a first moving end and a second moving end, the first moving end and the second moving end move towards each other or away from each other, and the moving direction is perpendicular to the conveying direction of the conveying belt 3; the principle is similar to that of the transverse sliding assembly, but the transverse sliding assembly is adapted to the width of the opening of the paper bag, and the longitudinal sliding assembly clamps the opening of the paper bag, thereby closing the paper bag.

[0077] The two rotating shafts 23 are rotatably connected with the first moving end and the second moving end respectively, the clamping plates 22 are fixedly connected with the first ends of the rotating shafts 23, and the two clamping plates 22 are arranged in parallel; the clamping plates 22 are components that directly contact and fold the paper bag, two clamping plates 22 are arranged on both sides of the opening of the paper bag, then the two clamping plates 22 are moved towards each other, and then the folding of the opening of the paper bag is realized through the rotation of the clamping plates 22.

[0078] The rotating assembly is in separable contact with the second ends of the rotating shafts 23, and the rotating assembly is used to drive the rotating shafts 23 to rotate.

[0079] The main working process is as follows:

[0080] Transverse adjustment: two sliding ends of the transverse sliding assembly move according to the width of the paper bag, so that the two folding assemblies reach the appropriate position.

[0081] Clamping: two moving ends of the longitudinal sliding assembly of each folding assembly are close to each other, so that the clamping plate 22 clamps the two sides of the paper bag.

[0082] Folding: the rotating assembly is in contact with the rotating shaft 23, which drives the rotating shaft 23 to rotate, thereby driving the clamping plate 22 to rotate, completing the folding of the paper bag.

[0083] Extraction: the two sliding ends of the transverse sliding assembly are reset, so that the clamping plate 22 is extracted from the opening of the folded paper bag.

[0084] Reset: the longitudinal sliding assembly is reset.

[0085] Example Two

[0086] As shown in Figure 1 , 3 , this embodiment explains the specific structure and working principle of the transverse sliding assembly, the longitudinal sliding assembly and the rotating assembly.

[0087] The transverse sliding assembly includes a sliding rail 24, a first sliding block 25, a second sliding block and a motor A 26.

[0088] The sliding rail 24 is arranged along the conveying direction of the conveying belt 3; the first sliding block 25 and the second sliding block are arranged in the sliding rail 24 and can slide along the sliding rail 24; the folding assembly is driven to approach or move away from the paper bag.

[0089] The motor A 26 is fixedly connected with the inner lining support frame 12 through a shaft support plate 27, and the torque output shaft of the motor A 26 is screw-connected with the first sliding block 25 and the second sliding block through a transverse rotating shaft 23, the screw rotation direction between the transverse rotating shaft 23 and the first sliding block 25 is opposite to that between the transverse rotating shaft 23 and the second sliding block; the transverse rotating shaft 23 can convert the rotary motion of the motor A 26 into the linear motion of the first sliding block 25 and the second sliding block, and by setting the screw rotation direction between the transverse rotating shaft 23 and the first sliding block 25 and the second sliding block to be opposite, when the motor A 26 rotates, the two sliding blocks can simultaneously move towards each other or in opposite directions, so as to realize the purpose of controlling the two sliding blocks with opposite directions of motion by one motor.

[0090] The upper ends of the two connecting shafts are respectively fixedly connected with the first sliding block 25 and the second sliding block perpendicularly.

[0091] The longitudinal sliding assembly includes a transmission shaft 28, a motor B 30, a first limiting block 29 and a second limiting block.

[0092] The transmission shaft 28 is fixedly connected with the shell surface 21 through the bearing seat 33 and is arranged along the direction perpendicular to the conveying direction of the conveying belt 3; the first limiting block 29 and the second limiting block are both threadedly connected with the transmission shaft 28, and the thread rotation direction between the transmission shaft 28 and the first limiting block 29 is opposite to the thread rotation direction between the transmission shaft 28 and the second limiting block; the transmission shaft 28 provides the thread basis for the movement of the first limiting block 29 and the second limiting block, and the two limiting blocks are simultaneously moved towards each other or reversely moved through the opposite thread arrangement.

[0093] The motor B30 is fixedly connected with the shell surface 21, and the torque output shaft of the motor B30 is fixedly connected with the transmission shaft 28; the transmission shaft 28 is driven by the motor B30 to change the positions of the first limiting block 29 and the second limiting block.

[0094] The first limiting block 29 and the second limiting block are both provided with a rotating hole along the conveying direction of the conveying belt 3, the rotating shaft 23 is arranged in the rotating hole and is rotatably connected with the rotating hole, the shell surface 21 is provided with a strip-shaped limiting hole parallel to the transmission shaft 28, and the first end of the rotating shaft 23 passes through the strip-shaped limiting hole and is fixedly connected with the clamping plate 22.

[0095] The rotating shaft 23 is arranged in the rotating hole and is limited by the strip-shaped limiting hole, so that the rotating shaft 23 can only move laterally in the strip-shaped limiting hole, thereby limiting the kinematic pair of the first limiting block 29 and the second limiting block to move along the axial direction of the transmission shaft 28 and cannot rotate around the transmission shaft 28, thereby forming a screw rod structure.

[0096] The rotating assembly comprises the limiting plate gear 31 and the motor C32.

[0097] The two limiting plate gears 31 are coaxially and fixedly connected with the second ends of the two rotating shafts 23, respectively;

[0098] The motor C32 is fixedly connected with the shell surface 21, and the torque output shaft of the motor C32 is connected with the driving gear 34;

[0099] When the first limiting block 29 and the second limiting block are at the minimum distance (i.e., when the clamping plate 22 completely clamps the paper bag), the two limiting plate gears 31 are engaged with the driving gear 34, and since the position of the clamping plate 22 at the fixed point is not on a horizontal line and a vertical line, the angle of 0-135 can be achieved.

[0100] The overall working process is as follows:

[0101] Lateral adjustment (adapt to the width of the paper bag): the motor A26 drives the lateral rotating shaft 23 to move the first sliding block 25 and the second sliding block on the sliding rail 24 to adjust the distance between the two paper folding assemblies.

[0102] Vertical adjustment (adapt to the height of the paper bag): the lifting device drives the inner liner support frame 12 to move downward, thereby moving the entire folding paper assembly downward, so that the height of the clamping plate 22 corresponds to the folding position.

[0103] Clamping: the motor B30 drives the transmission shaft 28, so that the first limiting block 29 and the second limiting block move towards each other, thereby driving the clamping plate 22 to clamp the two sides of the paper bag.

[0104] Folding: when the limiting block reaches the nearest position, the limiting plate gear 31 meshes with the drive gear 34 of the motor C32, and the motor C32 drives the clamping plate 22 to rotate, thereby completing the folding.

[0105] Extraction: the motor A26 drives the transverse rotating shaft 23, so that the two sliding ends (the first sliding block 25 and the second sliding block) of the transverse sliding assembly are reset, thereby driving the clamping plate 22 to be extracted from the opening of the folded paper bag.

[0106] Reset: the motor B30 reversely drives the transmission shaft 28, so that the first limiting block 29 and the second limiting block move in the opposite direction, thereby resetting the longitudinal sliding assembly and completely releasing the paper bag.

[0107] Through the control of the three motors (A, B, and C) on the three key actions (transverse adjustment, clamping, and folding), the automatic folding operation in the paper bag packaging process is realized.

[0108] Example Three

[0109] In order to improve the folding effect and prevent the creases of the paper bag from turning outward when the clamping plate 22 clamps the paper bag, the folding paper mechanism 2 further comprises a pressing rod 35, which is inclinedly arranged and fixedly connected at the lower end of the connecting shaft, and the upper end of the pressing rod 35 is arranged between the two clamping plates 22.

[0110] After the paper bag to be packaged is located on the conveying belt 3 and reaches the folding position, the folding paper mechanism 2 (including the pressing rod 35) is in the initial position (a certain height above the paper bag).

[0111] The lifting device starts to move downward, thereby driving the entire folding paper mechanism 2 to move downward. Since the pressing rod 35 is inclinedly arranged and fixed at the lower end of the connecting shaft, the lower end of the pressing rod 35 will contact the paper bag earlier than the clamping plate 22.

[0112] As the lifting device continues to move downward, the lower end of the pressing rod 35 exerts pressure on the paper bag, which will guide the creases inward along the original creases of the paper bag, so that the creases begin to bend inward, thereby forming an initial inward folding trend, and the creases will not turn outward when the clamping plate 22 is clamped.

[0113] Example Four

[0114] The paper bag packaging device further comprises a label sticking mechanism 4 fixedly connected with the inner liner support frame 12 and located at one side of the paper folding mechanism 2, and used for automatically sticking labels to the folded paper bags.

[0115] The storage form of the conventional label is usually to lay the labels on an oily paper surface, and to tear each label separately to achieve the use purpose. For this, we first use a suction cup to suck the label on the label paper, and move the label through the movement of the suction cup arm to achieve the purpose of sticking. However, it is found through practice that the label paper has a special property due to the sticking to the oily surface. When sucking the label, if the suction force is too small, the label paper cannot be taken off, and if the suction force is too large, the oily paper to which the label is stuck will also be sucked off. For this, we think of the manual tearing process of the label, and combining with the actual application, we innovatively propose a label sticking process, that is, four processes of "label edge lifting-label tearing-label positioning-label edge sticking". Through the research on these processes, we decide to adopt the idea of label tearing and sticking integration. We innovatively propose the concept of label "roll". The label is pulled out from the label roll, the label is lifted at the edge of the small cylindrical surface to achieve the process of sticking to the edge of the paper bag.

[0116] The label sticking process uses the label roll to drive the label to move, to achieve the process of self-adaptive edge lifting, edge sticking and edge sticking. When the clamping plate 22 fixes the folded edge of the paper bag, the motor D in the label sticking mechanism 4 drives the gear set 49 to rotate, to achieve the purpose of stretching the upper mechanism and tightening the lower mechanism. At the same time when the upper mechanism is stretched, the label is conveyed to the edge of the upper sticking mechanism. Through calculation and actual label movement practice, we find that when the oily surface to which the label is stuck is bent too much, the label will naturally stretch out on one side to achieve the purpose of edge lifting. After the edge lifting, the label sticking surface is stuck to the edge of the paper bag. With the continuous rotation of the motor, the label continuously moves and bends, and finally realizes the complete sticking of the label. After complete sticking, with the movement of the subsequent paper bag conveying belt 3, the label will also pass through the bristle surface to be pressed tightly to prevent the label from being stuck loosely.

[0117] The label sticking mechanism 4 comprises a rear plate 41, a label paper tape 45, a driven pulley 42, a driving pulley 43 and a convex belt assembly 44.

[0118] The rear plate 41 is fixed to the inner liner support frame 12 by screws; the driven pulley 42, the driving pulley 43 and the convex belt assembly 44 are in a triangular distribution, and the convex belt assembly 44 is arranged towards the paper bag 101 in the package; the label paper tape 45 is wound on the driven pulley 42, and one end of the label paper tape 45 is wound on the driving pulley 43 through the convex belt assembly 44, and the driving pulley 43 is driven to rotate by the motor D.

[0119] The convex belt assembly 44 comprises a convex belt bottom plate 46, a sticking convex strip 47, a tightening convex strip and a gear set 49.

[0120] The convex band base plate 46 is fixedly connected with the rear plate 41, providing a sliding platform for the pasting convex strip 47 and the tight convex strip 48.

[0121] The pasting convex strip 47 is horizontally arranged and is in sliding connection with the convex band base plate 46, and the sliding direction of the pasting convex strip 47 is horizontal and perpendicular to the label pasting position of the paper bag 101 in the package. The lower side of the pasting convex strip 47 is provided with a horizontal rack 50. The tight convex strip 48 is in sliding connection with the convex band base plate 46, and the sliding direction of the tight convex strip 48 is perpendicular to the sliding direction of the pasting convex strip 47. The tight convex strip 48 is provided with a vertical rack. The gear set 49 is in meshing with the horizontal rack 50 and the vertical rack, and is driven to rotate by the motor E.

[0122] With the intersection of the sliding directions of the pasting convex strip 47 and the tight convex strip 48 as a reference point, when the pasting convex strip 47 moves away from the reference point, the tight convex strip 48 moves towards the reference point. When the pasting convex strip 47 moves towards the reference point, the tight convex strip 48 moves away from the reference point.

[0123] The included angle between the two sections of the label paper tape 45 bypassing the pasting convex strip 47 is less than 90°, and the non-pasting surface of the label is adsorbed on the oily surface of the label paper bag. The pasting surface of the label is outwardly arranged, so that when the label paper tape 45 is pulled, the label will be separated from the oily surface due to the excessive bending angle when passing through the tip of the pasting convex strip 47.

[0124] The working process is as follows:

[0125] Initial state: The label paper tape 45 is wound on the driven pulley 42, passes through the convex band assembly 44, is wound on the driving pulley 43, and the non-pasting surface of the label is adsorbed on the oily surface of the label paper tape 45.

[0126] Pulling the label paper tape 45: the motor D drives the driving pulley 43 to rotate, and pulls the label paper tape 45.

[0127] Label separation: when the label paper tape 45 passes through the tip of the pasting convex strip 47, the label will be separated from the oily surface due to the bending angle of the label paper tape 45 being less than 90°, and the pasting surface of the label is outwardly arranged.

[0128] Pushing out the label: the motor E drives the gear set 49 to rotate, and since the gear set 49 is in meshing with the racks of the pasting convex strip 47 and the tight convex strip 48, the pasting convex strip 47 moves towards the paper bag, pushing the separated label to the paper bag. At the same time, the tight convex strip 48 moves upwards.

[0129] Pasting the label: the pasting convex strip 47 pushes the label to the designated position of the paper bag, and the pasting is completed.

[0130] Reset: the motor E reverses the drive gear 34 group 49, the sticking convex strip 47 retracts, the tight convex strip 48 moves down, keeps the tension of the label paper tape 45, and prepares for the next sticking. It needs to be particularly pointed out that the retracting action of the sticking convex strip 47 is crucial. After completing a label sticking, if the sticking convex strip 47 remains extended, it will hinder the next paper bag to be packaged into the folding paper position, or interfere with the rotating path of the clamping plate 22 in the folding paper mechanism 2, causing the folding paper action to be unable to be completed smoothly. Therefore, the timely retraction of the sticking convex strip 47 ensures the continuity and reliability of the entire packaging process, avoids interference between mechanisms, and ensures that the equipment can efficiently and smoothly perform continuous packaging operations.

[0131] In addition, in order to better realize the full-automatic packaging of the paper bag, the device is equipped with an electric control mainboard, a control unit, and a user interaction system. After the user inputs the relevant information, the interaction system converts the information into corresponding commands and transmits them to the central control system. The central control system accepts and processes the information and transmits the commands to the lifting control unit and the clamping device control unit. Each unit processes the commands into electrical signals and transmits them to the corresponding motors to achieve corresponding mechanical movements, which better cooperates to realize the full automation of the equipment.
