Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a bag opening sorting device for packaging. Background Technology

[0002] In modern packaging processes, mechanical devices are often used to open and clamp the bag opening, then various materials are poured into the bag. After that, the mechanical devices are removed from opening the bag, and a bag opening straightening device is used to smooth out any wrinkles or folds before sealing the bag.

[0003] This type of bag-mouth finishing device causes the lower half of the bag to spread out due to the material expanding the bag body after filling. It also pulls the bag mouth to straighten and separate, resulting in unevenness on the upper and lower sides of the bag, which affects the finishing and sealing of the bag mouth. Utility Model Content

[0004] This utility model provides a bag opening straightening device for packaging, which, after the packaging bag is filled, straightens and aligns the top and bottom ends of the bag, helping the filler to be evenly distributed inside the bag and keeping the top and bottom of the bag in a neat state before sealing. This solves the problems mentioned in the background art, namely:

[0005] After the filling is completed, the bottom of the packaging bag is stretched and spread out by the material, which at the same time pulls the bag opening to straighten and separate it, making the top and bottom of the packaging bag uneven, thus affecting the bag opening arrangement and sealing.

[0006] To achieve the above objectives, this utility model provides a bag opening sorting device for packaging, including a base, a lifting mechanism, and a sealing assembly. The lifting mechanism is located at the bottom inner side of the base, and the sealing assembly is located at the middle inner side of the base, with the sealing end of the sealing assembly facing the lifting path of the lifting mechanism.

[0007] A bag opening straightening mechanism includes a lifting component, a mounting base, and a bag opening stretching assembly. The lifting component is located at the top of the base, the mounting base is located at the lifting end of the lifting component, and the bag opening stretching assembly is located on the mounting base with its sides facing the sealing end of the sealing assembly. This allows the bag opening stretching assembly to stretch and straighten the sides of the bag opening, facilitating sealing by the sealing assembly.

[0008] Based on this, the bag opening assembly includes a driving component, a guide shaft, and a bag opening bracket. The driving components are arranged in pairs and horizontally on both sides of the mounting base. The guide shaft is horizontally located at the bottom of the mounting base. The bag opening brackets are slidably mounted on the guide shaft in pairs, and the two bag opening brackets are respectively connected to the output ends of the two driving components, so that the two bag opening brackets maintain a tendency to move in opposite directions.

[0009] The support frame is an L-shaped frame, and its vertical frame is located above the sealing end of the sealing assembly.

[0010] In this technical solution, the vertical frames of two opening supports are separated from each other to open the bag opening. When the two opening supports are taut, the vertical frames of the two opening supports are located on both sides of the sealing end of the sealing component to prevent interference with the sealing component's sealing of the bag.

[0011] As a further embodiment of this utility model, the lifting mechanism includes a lifting base, a flattening component, and a sorting and pressing component. The lifting base is located at the bottom of the inner side of the base. The lifting base includes a lifting platform directly facing the sealing component. The flattening component is located on both sides of the lifting platform. The sorting and pressing component is located on both sides and is positioned above the flattening component.

[0012] Based on this, the flattening component includes a drive cylinder and a pressing plate. The drive cylinder is located on one side of the lifting platform, and the pressing plate is located on the output end of the drive cylinder. The pressing plates of the two flattening components are vertically distributed on both sides of the lifting platform, so that the drive cylinder can drive the pressing plates to move in opposite directions. At this time, after the packaging bag is filled on the lifting platform, it is flattened in opposite directions using the pressing plates.

[0013] The sorting and extrusion component includes a control component and a sorting frame. The control component is located at one end of the lifting platform, and the sorting frame is connected to the output end of the control component.

[0014] The two sorting racks have interlocking frames, which, when brought close together, can press the bag together to form a wavy cross-section at the bag opening, thus sorting the bag opening.

[0015] In this technical solution, the packaging bag placed on the lifting platform, after being filled with material, can be flattened by the flattening component pressing both sides of the packaging bag, thereby flattening the entire packaging bag and the internal material, preventing the material from accumulating at the bottom of the packaging bag. In addition, after flattening the packaging bag and the material, the sorting and squeezing component can press the bag body part above the material and below the bag opening, sorting the bag body into a close fit, which is convenient for subsequent opening and sealing of the bag opening.

[0016] Compared with the prior art, the present invention provides a bag opening sorting device for packaging, which has the following beneficial effects:

[0017] This invention uses a driving cylinder to move a pressing plate in opposite directions and squeeze the material piled up at the bottom of the packaging bag, eliminating the bottom accumulation. Then, a control unit controls the sorting frame to move in opposite directions, using the staggered sorting frame to squeeze the packaging bag to form a wave-shaped cross section, reshaping the bag's structure. Finally, a driving unit drives L-shaped opening support frames to move away from each other, precisely opening the bag opening, forming a progressive packaging bag sorting process. This process aligns the top and bottom of the packaging bag, helping the filler to be evenly distributed inside the bag, keeping the top and bottom of the bag neat and completing the sealing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 5As shown, in order to tidy up and level the top and bottom sides of the packaging bag, and to evenly distribute the filler inside the packaging bag, preventing the filler from accumulating in the lower half of the packaging bag and affecting the bag opening and sealing, a base 1, a lifting mechanism 2, and a sealing assembly 3 are provided. The lifting mechanism 2 is located at the bottom inside the base 1, and the sealing assembly 3 is located at the middle inside the base 1, with the sealing end of the sealing assembly 3 facing the lifting path of the lifting mechanism 2.

[0026] The bag opening sorting mechanism 4 includes a lifting component 41, a mounting base 42, and a bag opening spreading component 43. The lifting component 41 is located at the top of the base 1, the mounting base 42 is located at the lifting end of the lifting component 41, and the bag opening spreading component 43 is located on the mounting base 42. The bag opening spreading component 43 is directly opposite to both sides of the sealing end of the sealing component 3, so that the bag opening spreading component 43 can spread and straighten the two sides of the bag opening, and facilitate the sealing component 3 to seal.

[0027] The bag opening assembly 43 includes a drive member 431, a guide shaft 432, and a bag opening bracket 433. The drive members 431 are arranged in pairs and horizontally on both sides of the mounting base 42. The guide shaft 432 is horizontally located at the bottom of the mounting base 42. The bag opening brackets 433 are slidably mounted on the guide shaft 432 in pairs. The two bag opening brackets 433 are respectively connected to the output ends of the two drive members 431, so that the two bag opening brackets 433 maintain a tendency to move in opposite directions.

[0028] Reference Figure 3 and Figure 4 As shown, the mouth support frame 433 is an L-shaped frame, and its vertical frame is located above the sealing end of the sealing component 3. This allows the vertical frames of the two mouth support frames 433 to separate and open the bag opening. When the two mouth support frames 433 are taut, their vertical frames are located on both sides of the sealing end of the sealing component 3, preventing interference with the sealing component 3's sealing of the bag. This creates a spatially staggered layout between the vertical frames of the mouth support frame 433 and the sealing component 3, ensuring that the bag opening is fully opened while also ensuring zero interference between the opening mechanism and the sealing component 3.

[0029] Reference Figure 2 and Figure 5As shown, the lifting mechanism 2 includes a lifting base 21, a flattening component 22, and a sorting and squeezing component 23. The lifting base 21 is located at the bottom inner side of the base 1. The lifting base 21 includes a lifting platform 211 facing the sealing component 3. The flattening component 22 is located on both sides of the lifting base 21 and the sorting and squeezing component 23 is located on both sides and above the flattening component 22. This allows the packaging bag placed on the lifting platform 211 to be squeezed against both sides of the packaging bag by the flattening component 22 after the material filling is completed, thereby flattening the entire packaging bag and the internal material. This prevents the bottom of the packaging bag from becoming taut due to the accumulation of material at the bottom of the packaging bag, which would affect the sealing of the bag opening. In addition, after flattening the packaging bag and the material, the sorting and squeezing component 23 can squeeze the bag body part above the material and below the bag opening, and sort the bag body part into a close-fitting state. At this time, it is convenient to open and seal the bag opening.

[0030] Reference Figure 2 and Figure 5 As shown, the flattening component 22 includes a drive cylinder 221 and a pressing plate 222. The drive cylinder 221 is located on one side of the lifting platform 211, and the pressing plate 222 is located on the output end of the drive cylinder 221. The pressing plates 222 of the two flattening components 22 are vertically distributed on both sides of the lifting platform 211, so that the drive cylinder 221 can drive the pressing plate 222 to move in opposite directions. At this time, after the packaging bag is filled on the lifting platform 211, it is flattened in opposite directions by the pressing plate 222.

[0031] Reference Figure 2 and Figure 5 As shown, the sorting extrusion component 23 includes a control component 231 and a sorting frame 232. The control component 231 is located at one end of the lifting platform 211, and the sorting frame 232 is connected to the output end of the control component 231.

[0032] The frame parts of the two sorting racks 232 are interlocked, so that when the frames of the two sorting racks 232 are close together, the sorting racks 232 can squeeze the bag body together and form an interlocked state, forming a wavy cross section of the bag opening, thus completing the sorting of the bag opening.

[0033] It needs to be clarified that the bottom accumulation is eliminated by the horizontal bidirectional extrusion of the flattening component 22, the bag structure is reshaped by the wavy cross section formed by the staggered sorting frame 232, and finally the bag opening is precisely opened by the L-shaped opening support frame 433, forming a progressive bag sorting process.

[0034] Working principle: The packaging bag is placed on the lifting platform 211 to complete the filling process. After filling, the packaging bag is filled with material and its bottom is expanded. At this time, two drive cylinders 221 are activated to drive two pressing plates 222 to move in opposite directions and squeeze the sides of the packaging bag, thereby flattening the entire packaging bag and the internal material. This prevents the packaging bag from expanding due to material accumulation at the bottom. Then, two control components 231 drive two sorting frames 232 to move in opposite directions. The two sorting frames 232 squeeze the part of the bag body above the material and below the bag opening, allowing this part of the bag body to... The bags are then joined together in an interlaced manner, forming a wavy cross-section at the bag opening, thus completing the bag opening preparation. At this point, the lifting mechanism 2 is activated, using the lifting platform 211 to lift the entire packaging bag, allowing the bag opening to be inserted into the sealing end of the sealing component 3. Then, the lifting component 41 is activated, causing the mounting base 42 to move down and be positioned directly above the bag opening. At this point, the driving component 431 is activated, driving the two support frames 433 to move in opposite directions. The vertical frame of the support frame 433 is used to open both sides of the bag opening, straightening the bag opening. Finally, the sealing component 3 completes the sealing of the packaging bag.
