Description

Technical Field

[0001] This invention relates to the field of sealing device technology, specifically to a fully automatic high-speed bagging machine sealing device and sealing method. Background Technology

[0002] The sealing device of a bagging machine is an important component of the bagging machine. It is used to seal the bags to ensure the airtightness of the products. In the continuous high-speed sealing process, the sealing device needs to have a stable working state to ensure the efficiency and quality of automated high-speed bag sealing.

[0003] Currently, the sealing process of sealing devices mainly involves using a clamping device to deliver the packaged bag to the sealing work area, and then pressing and heat-sealing the bag opening. However, when heat-sealing the packaged bag after it has been filled with materials, the sealing quality and the stability of the continuous sealing process still need to be further improved. This is because the packaged bag will undergo certain deformation after being filled with materials, which can easily affect the shape of the bag opening. Simple clamping and fixing is not enough to maintain the stability of the bag opening shape, which in turn affects the sealing quality and the stability of the sealing process. Consequently, it will affect the working efficiency and quality of automated high-speed bag packaging. Summary of the Invention

[0004] This invention provides a fully automatic high-speed bagging machine sealing device and sealing method to solve the problem that the stability of the continuous sealing process and the stability of the sealing quality need to be improved in related technologies.

[0005] This invention provides a sealing device for a fully automatic high-speed bagging machine. The sealing device includes a pressing and sealing mechanism with a sorting part. The sorting part includes a symmetrically arranged base and a primary sorting component and a secondary sorting component arranged on the base. The secondary sorting components are symmetrically distributed and located on both sides of the primary sorting component. The symmetrical secondary sorting components open and close synchronously, while the primary sorting component reciprocates and translates. A clamping and picking mechanism for a sorting part is provided. The sorting part includes a connecting frame with a limiting component that is rotatably set. The limiting component is a plate-shaped structure and an initial suppressing component is provided between it and the connecting frame. Under the suppression of the initial suppressing component, the initial state of the limiting component is inclined.

[0006] In one possible implementation, both the primary and secondary finishing components include finishing strips and finishing rollers that are rotatably embedded in the finishing strips. The finishing strips in the primary finishing components, which are symmetrical to each other on the symmetrical base, are symmetrical to each other, and the finishing rollers on the finishing strips are staggered but parallel to each other. The finishing strips in the secondary finishing components, which are symmetrical to each other on the symmetrical base, are symmetrical to each other, and the finishing rollers on the finishing strips are staggered but parallel to each other.

[0007] In one possible implementation, a synchronization component is provided between the symmetrical secondary sorting components to control the reciprocating translation of the primary sorting component. The synchronization component includes a lifting frame with toothed segments and a rotating shaft with a toothed ring. The rotating shaft is fixedly connected to the rotation point of the secondary sorting component. The lifting frame is disposed between the primary sorting component and the base, and the lifting frame is engaged with the toothed ring through its toothed segments.

[0008] In one possible implementation, the pressing and sealing mechanism includes a front pressure plate and a rear pressure plate, which are symmetrically arranged and move synchronously in opposite directions. The finishing part also includes a linkage control component, which includes a control bar, a gear conversion assembly, and a limiting plate corresponding to the control bar. The control bar and the gear conversion assembly are both set on the base, and the limiting plate corresponds one-to-one with the control bar. At the same time, the limiting plate is correspondingly set on the front pressure plate and the rear pressure plate. During the synchronous relative movement of the front pressure plate and the rear pressure plate to perform pressing and sealing, the linkage control component automatically drives the secondary finishing part to rotate.

[0009] In one possible implementation, a top support is provided between the bases, and a limiting block is provided on the base to cooperate with the top support. The top support moves outward synchronously through the limiting block.

[0010] A sealing method for a fully automatic high-speed bagging machine, using a fully automatic high-speed bagging machine sealing device, includes the following steps: S1: Material picking, the bag is picked up by a clamping and placing mechanism, and the bag is constrained and shaped by a sorting part during the clamping process; S2: Material feeding, based on S1, the clamping and placing mechanism feeds the bag into the bag and places its opening within the working range of the pressing and sealing mechanism; S3: Pressing and sealing, based on S2, the opening of the bag is pressed and sealed, and before pressing and sealing, the bag opening is quickly sorted by a sorting part; S4: Reset and repeat the above steps.

[0011] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0012] 1. The fully automatic high-speed bagging machine sealing device and sealing method provided by the present invention, during the sealing process, utilizes a two-stage sorting unit to sort and constrain the state of the sealed bag, so that the sealed bag is in a relatively flat and uniform state. Combined with the further sorting of the bag opening before pressing and sealing by the first-stage sorting unit, the bag opening is in a relatively flat and stable state ready for sealing, which effectively improves the stability of the sealing process and the sealing quality, and is conducive to the continuous and stable completion of the sealing work of the sealed bag, thereby improving the work efficiency and work quality of integrated packaging.

[0013] 2. According to the embodiments of the present invention, a fully automatic high-speed bagging machine sealing device and sealing method are provided. During the process of limiting and shaping the packaged bag, the limiting component gradually changes from an inclined state to a vertical state, which is conducive to quickly and smoothly limiting and shaping the packaged bag, making it more neat, thereby improving the neatness of the bag opening, facilitating subsequent pressing and sealing processing, improving the quality of sealing and the stability of continuous sealing processing.

[0014] 3. The sealing device and sealing method of the fully automatic high-speed bagging machine provided by the present invention quickly sorts the bag opening through the left and right opening auxiliary sorting parts and the up and down moving positive sorting parts, effectively improving the flatness of the bag opening.

[0023] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Please see Figure 1 Figure 2 A fully automatic high-speed bagging machine sealing device includes a pressing and sealing mechanism 2 with a sorting part 1 and a clamping and picking mechanism 4 with a sorting part 3. Both the pressing and sealing mechanism 2 and the clamping and picking mechanism 4 are mounted on a frame (the structural diagram of the frame is not shown in the figure). During the sealing process, the clamping and picking mechanism 4 clamps the packaged bag containing the material and sends it to the sealing station. During the clamping process, the sorting part 3 automatically sorts and constrains the state of the packaged bag, so that the packaged bag is in a relatively flat and uniform state, which is conducive to improving the stability of the bag opening state. After that, during the sealing process at the sealing station, the sorting part 1 will further sort the bag opening before pressing and sealing, so that the bag opening is in a relatively flat and stable state before sealing, which is conducive to improving the sealing quality and the stability of the sealing process. In summary, in the process of fully automatic high-speed bagging, the sealing work of the packaged bag can be completed continuously and stably, while effectively ensuring the sealing quality and improving the efficiency and quality of fully automatic integrated sealing work.

[0025] See Figure 1 and Figure 3The clamping and placing mechanism 4 includes symmetrically arranged placing seats 401 on the left and right sides. Clamping plates 402 are symmetrically arranged on the placing seats 401, and the clamping plates 402 are rotatably connected to the placing seats 401. The sorting part 3 includes a connecting frame 302 with a limiting member 301 rotatably mounted. The connecting frame 302 corresponds one-to-one with the clamping plates 402 and is fixedly connected to them. The limiting member 301 has a plate-like structure and an initial suppressing member 303 is provided between it and the connecting frame 302. Under the suppression of the initial suppressing member 303, the initial state of the limiting member 301 is inclined. Figure 1 and Figure 3 As shown, during the process of the clamping plate 402 rotating from the unfolded state to the clamping state, the connecting frame 302 drives the limiting member 301 to rotate accordingly. During the rotation, the limiting member 301 contacts the packaging bag and limits and shapes the packaging bag, improving the flatness and uniformity of the packaging bag. In addition, considering the large deformation of the bottom of the packaging bag after the material is filled, the limiting member 301 is set to an inclined position. During the limiting and shaping process, the bottom area of ​​the limiting member 301 will first contact the bottom area of ​​the packaging bag and apply a certain force. As the clamping plate 402 rotates, the limiting member 301 continues to move towards the packaging bag to limit and shape it. As the limiting member 301 moves, the reaction force of the packaging bag will cause it to gradually change from an inclined state to a vertical state. During this process, the limiting member 301 will push the material in the packaging bag upward, which is conducive to quickly and smoothly limiting and shaping the packaging bag, making it more neat, and thus improving the neatness of the bag opening, which is convenient for subsequent pressing and sealing.

[0026] See Figure 1 , Figure 2 and Figure 4 The sorting unit 1 includes a base 101 symmetrically arranged front and back, and a main sorting component 102 and a secondary sorting component 103 disposed on the base 101, such as... Figure 2 As shown, the base 101 includes two symmetrical base blocks. The auxiliary sorting components 103 are symmetrically distributed on the left and right and are located on both sides of the positive sorting component 102. The positive sorting component 102 is slidably arranged up and down. The auxiliary sorting components 103 are rotatably connected to the corresponding base 101. The positive sorting components 102 on the symmetrical base 101 are symmetrical to each other, and the auxiliary sorting components 103 are symmetrical to each other. When the bag opening is placed in the sealing position, before the sealing is pressed, the auxiliary sorting components 103 and the positive sorting components 102 on the symmetrical base 101 will clamp the bag opening from the front and rear sides. At the same time, the symmetrical auxiliary sorting component 103 on the left rotates to the left and the symmetrical auxiliary sorting component 103 on the right rotates to the right. Meanwhile, the symmetrical positive sorting component 102 moves upward and quickly sorts the clamped bag opening, effectively improving the flatness of the bag opening and facilitating the subsequent smooth and stable sealing process.

[0027] See Figure 2 , Figure 6 and Figure 7 The finishing part 1 also includes a connecting seat 108. A base 101 is elastically and slidably connected to the connecting seat 108. A top support 106 is provided between the bases 101. The top support 106 is slidably connected to the connecting seat 108 and is a sliding block with a protruding part in the middle. A limiting block 107 is provided on the base 101 to cooperate with the top support 106. The limiting block 107 has an arc-shaped structure. Under normal conditions, the symmetrical bases 101 are in a close-fitting state, and the corresponding finishing parts 102 and 103 are also in a close-fitting state. In the process of the clamping and placing mechanism 4 clamping and feeding the sealed bag so that the bag opening enters the sealing station, the top support 106 slides upward through the limiting block 107 to open the base 101, so that the corresponding positive sorting part 102 and the secondary sorting part 103 on it are separated and maintain a certain distance for the bag opening to pass through. Then, when the protruding part on the top support 106 is misaligned with the limiting block 107, the base 101 automatically resets under the action of elastic force, and the corresponding positive sorting part 102 and the secondary sorting part 103 reset and clamp the bag opening, which facilitates the subsequent sorting work.

[0028] See Figure 2 and Figure 5 Both the primary sorting component 102 and the secondary sorting component 103 include sorting strips and sorting rollers that are rotatably embedded in the sorting strips. The sorting strips in the symmetrical primary sorting component 102 are symmetrical to each other, and the sorting rollers on the sorting strips are staggered but parallel to each other. The sorting strips in the symmetrical secondary sorting component 103 on the symmetrical base 101 are symmetrical to each other, and the sorting rollers on the sorting strips are staggered but parallel to each other. During the process of sorting the bag opening by moving the primary sorting component 102 upward, rotating the left symmetrical secondary sorting component 103 to the left, and rotating the right symmetrical secondary sorting component 103 to the right, the staggered sorting rollers help to improve the sorting effect and the convenience of sorting.

[0029] See Figure 2 , Figure 4 and Figure 6 A synchronization component 104 is provided between the symmetrical secondary sorting components 103 to control the reciprocating translation of the primary sorting component 102. The synchronization component 104 includes a lifting frame 124 with toothed segments 114 and a rotating shaft 144 with a toothed ring 134. The rotating shaft 144 is fixedly connected to the rotation point of the secondary sorting component 103. The lifting frame 124 is located between the primary sorting component 102 and the base 101. The lifting frame 124 is connected to the toothed ring 134 through the meshing of the toothed segments 114. During the rotation of the secondary sorting component 103, the meshing of the toothed ring 134 and the toothed segments 114 on the rotating shaft 144 drives the lifting frame 124 to move upward. The lifting frame 124 drives the secondary sorting component 103 upward, thus linking the sorting process of the primary sorting component 102 with the connection process of the secondary sorting component 103.

[0030] See Figure 1 , Figure 2 and Figure 6 The sealing mechanism 2 includes a front pressure plate 201 and a rear pressure plate 202, which are symmetrically arranged and move synchronously in opposite directions. A heat-sealing area is provided on the pressing surface of the rear pressure plate 202. The sealing process is achieved by pressing the bag opening through the front pressure plate 201 and the rear pressure plate 202. The finishing part 1 also includes a linkage control component 105. The linkage control component 105 automatically drives the finishing part 1 to finish the bag opening during the synchronous relative sliding of the front pressure plate 201 and the rear pressure plate 202 to seal the bag opening, thereby improving the sealing quality and the stability of the sealing process. Figure 6 As shown, the linkage control component 105 includes a control bar 115, a gear conversion assembly 125, and a limiting plate 135 corresponding to the control bar 115. The control bars 115 are respectively disposed on the base 101 and can slide elastically back and forth. The limiting plates 135 correspond one-to-one with the control bars 115. The limiting plate 135 corresponding to the control bars 115 on the front base 101 is fixedly installed on the front pressure plate 201, and the limiting plate 135 corresponding to the control bars 115 on the rear base 101 is fixedly installed on the rear pressure plate 202. The gear conversion assembly 125 is respectively disposed on the base 101 and includes two meshing bevel gears and a spur gear. One of the bevel gears is coaxial and fixedly connected to the rotating shaft. On 144, another bevel gear is coaxial with and fixedly connected to the spur gear. The spur gear meshes with the control bar 115. During the synchronous relative movement of the front pressure plate 201 and the rear pressure plate 202 for pressing and sealing, both are set on the base 101. The limiting plate 135 corresponds one-to-one with the control bar 115. At the same time, the limiting plate 135 is correspondingly set on the front pressure plate 201 and the rear pressure plate 202. During the synchronous relative movement of the front pressure plate 201 and the rear pressure plate 202 for pressing and sealing, the corresponding limiting plate 135 pushes the corresponding control bar 115 to slide. During the sliding process, the control bar 115 drives the spur gear to rotate. The spur gear drives the rotating shaft 144 to rotate through the bevel gear, thereby driving the auxiliary sorting part 103 to rotate.
