Packaging bags play a vital role in modern commerce, as they not only protect goods from damage, but also enhance brand image, attract consumer attention through design, printing and material selection.

[0003] Taking a paper bag as an example, paper bags have the characteristics of environmental protection and practicality, and have been widely promoted and used in recent years, thereby promoting the rapid development of paper bag automatic forming technology. Common automatic forming machines for paper bags generally stamp sheet material into a three-dimensional bag shape through a forming die. During the forming process, the sheet material is stamped into a three-dimensional bag shape by the forming die, and then the side edges of the sheet material are squeezed by a side insertion mechanism, so that the side edges of the sheet material are attached to the side edges of the forming die, and the side edges of the sheet material are glued together. However, the existing forming die and side insertion mechanism are made of metal material, and the side insertion mechanism and the forming die are in rigid contact during the paper bag forming process, which produces a rigid impact during the paper bag forming process, affecting the quality of the side edge glue of the paper bag and the forming die or the side insertion mechanism is easily damaged.

[0063] Packaging bags are bags used to package goods. They vary in material, shape, size, and purpose to meet the protection, storage, transportation, and sales needs of different products. Most existing packaging bags are made by pressing or stamping sheet material into a three-dimensional shape using forming molds. Taking paper bags as an example, paper bags are environmentally friendly and practical, and have been widely promoted and used in recent years, thus prompting the rapid development of fully automated paper bag forming technology. Common automatic paper bag forming machines generally stamp sheet material into a three-dimensional bag shape using forming molds. During the forming process, the forming mold presses the sheet material into a three-dimensional bag shape, and then a side-insertion mechanism squeezes the sides of the sheet material, causing the sides of the sheet material to adhere to the sides of the forming mold. Adhesive is then used to bond the sides of the sheet material together. However, existing forming molds and side-insertion mechanisms are made of metal, resulting in rigid contact between the side-insertion mechanism and the forming mold during the paper bag forming process. This rigid impact affects the quality of the adhesive bonding on the sides of the paper bag, and the forming mold or side-insertion mechanism is easily damaged.

[0064] To solve the above-mentioned technical problems, this utility model discloses a side insertion structure for a bag forming machine. The structure of the bag forming machine is improved by setting a flexible extrusion part on the side of the side insertion plate of the side insertion mechanism facing the side panel of the forming mold. This has good surface shape adaptability, and the extensibility of the flexible structure increases the extrusion pressure, ultimately avoiding rigid impact between the side insertion mechanism and the forming mold during the paper bag forming process, and improving the forming effect of the paper bag.

[0065] See Figure 1 Before explaining the side insertion structure 300 of the bag forming machine disclosed in this embodiment, the structure of the forming mold 100, sheet holder 200, and sheet 700 related to the bag forming machine will be described first.

Figure 5 It is to be noted that the sheet material 700 comprises a handle 740 and is provided with a side edge 710 and a wrapping edge 720 on both sides, the wrapping edge 720 is shorter than the side edge 710, when the sheet material 700 is in a "U" shape, the wrapping edge 720 is located at the bottom of the sheet material 700, the side edge 710 further has a wider edge, the edge part of the wider edge is provided with a glue-coated edge 730, and the sheet material 700 is formed into a bag body, and the handle 740 is located in the interior of the bag body.

[0067] Next, the specific structure of the side insertion structure 300 of the bag body forming machine is explained.

[0068] The embodiment discloses a side insertion structure 300 of a bag body forming machine, referring to Figure 1 and Figure 2 , the bag body forming machine comprises a forming mold 100 in a cuboid shape, the forming mold 100 is provided below with a sheet material rack 200 for placing the sheet material 700, the forming mold 100 has a bottom plate 110 for pressing the sheet material 700, front side plates 120 and side plates 130, the front side plates 120 and the side plates 130 are erected around the bottom plate 110 and are connected with the end of the bottom plate 110. The bag body forming chamber 201 is arranged below the sheet material rack 200, the side insertion structure 300 is arranged in the bag body forming chamber 201 and is located at the side of the forming mold 100 in the vertical direction.

[0069] The side insertion structure 300 comprises an adhesive insertion plate 310, which is arranged in the side of the forming mold 100 and is arranged in the side of the corresponding side panel 130 of the forming mold 100 in a spaced manner. The side panel 130 of the corresponding side of the forming mold 100 has a bonding effect part 160 corresponding to the side part of the bag body to be bonded, and the adhesive insertion plate 310 is aligned with the bonding effect part 160 of the side panel 130 of the corresponding side of the forming mold 100 in the horizontal direction, and the width size of the adhesive insertion plate 310 is equal to or greater than the width size of the bonding effect part 160, and the height size of the adhesive insertion plate 310 is equal to or greater than the height size of the side panel 130 of the corresponding side. The bonding effect part 160 is part of the side of the side panel 130 of the corresponding side of the forming mold 100.

[0070] For example, the width size of the adhesive insertion plate 310 can be equal to or greater than the width size of the bonding effect part 160, such as 20 mm, 25 mm, 30 mm, etc., and the height size of the adhesive insertion plate 310 can be equal to or greater than the height size of the side panel 130 of the corresponding side, such as 20 mm, 25 mm, 30 mm, etc. Those skilled in the art can design according to actual needs, and the present embodiment does not make specific limitations.

[0071] It should be noted that the volume of the bag body forming chamber 201 needs to be slightly larger than the volume of the forming mold 100, so that the forming mold 100 can punch the sheet material 700 into a "U" shape. The adhesive insertion plate 310 can be a flat plate, or can be a "convex" plate according to the needs, or can be a plate structure of other shapes according to the needs, and the present embodiment does not make specific limitations.

[0072] Next, referring to Figure 1 , Figure 3 and Figure 5 the side part of the bag body to be bonded and the bonding effect part 160 are explained and described: first, referring to Figure 5 , the side part of the bag body to be bonded at least includes the side edge 710, the edge 720 and the glue coating edge 730 of the sheet material 700. When the forming mold 100 presses the sheet material 700, the glue coating edge 730 is sprayed with glue through the glue nozzle, and a line-shaped glue is formed on the glue coating edge 730. When the forming mold 100 presses the sheet material 700 into a "U" shape, the side edge 710, the edge 720 and the glue coating edge 730 are located at the side panel 130 of the forming mold 100, and the side edge 710, the edge 720 and the glue coating edge 730 of the sheet material 700 are the side part to be bonded. The bonding effect part 160 of the forming mold 100 can be seen from Figure 3When the forming mold 100 presses the sheet material 700 into a "U" shape, the side edge 710, the edge 720 and the glue edge 730 need to be pressed and adhered by glue to form the side edge 710 of the bag body. During the process of adhering the side edge 710, the edge 720 and the glue edge 730 together, the side edge 710 of the forming mold 100 needs to provide a planar action part for the sheet material 700 to adhere the side edge 710, the edge 720 and the glue edge 730 together. Therefore, the side edge 710 of the forming mold 100 has a bonding action part 160. The bonding action part 160 is pushed against and makes the side edge 710, the edge 720 and the glue edge 730 adhere to one side of the bonding action part 160 by the adhesive insert plate 310, so that the two side edges 710 and the two edges 720 are overlapped together, and the glue edge 730 and the side edge 710 are overlapped together, and the edge 720 is located inside, and then adhered together by glue.

[0073] The flexible extrusion part 320 is arranged on one side of the adhesive insert plate 310 and extends opposite and parallel to the side panel 130 on one side. When the forming mold 100 presses the sheet material 700 into the bag body forming chamber 201 and makes the sheet material 700 into a "U" shape, the adhesive insert plate 310 can move towards one side of the side panel 130, and the flexible extrusion part 320 presses one side of the sheet material 700 and the sheet material 700 is clamped between the flexible extrusion part 320 and the corresponding side panel 130 on one side of the forming mold 100. Specifically, in this embodiment, the flexible extrusion part 320 needs to cover at least the side panel 130 towards one side of the side panel 130. The flexible extrusion part 320 is a flexible pad with a certain thickness arranged on one side of the adhesive insert plate 310.

[0074] With the structure disclosed in this embodiment, the forming mold 100 presses and punches the sheet material 700 into a "U" shape, and then the side insertion structure 300 pushes and adheres the side edges 710 of the sheet material 700 together. The side panel 130 on one side of the forming mold 100 has a bonding action part 160 for providing a bonding plane for the side of the sheet material 700. The adhesive insert plate 310 is accurately aligned with the bonding action part 160 of the side panel 130 of the forming mold 100 in the horizontal direction, which ensures that the bonding position between the side of the bag body and the side panel 130 of the mold is accurate. The increased bonding area helps to disperse stress, improve the carrying capacity and anti-deformation ability of the entire structure, and the bonding action part 160 can provide an adhesive position for bags of different sizes and different volumes.

[0075] Further, the adhesive insert plate 310 disclosed in the embodiment is provided with a flexible extrusion part 320 near the side of the side panel 130, which can first increase the contact area, and through the flexible and elastic properties, ensure sufficient contact and close bonding between the adhesive insert plate 310 and the sheet material 700 of the side panel 130. When the flexible extrusion part 320 is subjected to external force, it can absorb and disperse stress and enhance the load-bearing capacity of the entire structure, thereby protecting the bonding site from damage. The flexible extrusion part 320 has certain plasticity and deformation ability, and can adapt to the bonding action part 160 on the side panel 130 of different shapes and sizes, and due to the presence of the flexible extrusion part 320, the bonding process of the side of the sheet material 700 is more efficient and fast.

[0076] In summary, the design of the adhesive insert plate 310 provided with the flexible extrusion part 320 near the side of the side panel 130 has significant advantages in improving the bonding effect, enhancing the structural strength, adapting to different shapes and sizes, simplifying the operation process, improving the production efficiency, and protecting the bonding site.

[0077] The embodiment also discloses a side insertion structure 300 of a bag body forming machine, please refer to Figure 2 and Figure 4 The adhesive insert plate 310 comprises a first abutting part 311 and a second abutting part 312 opposite to the corresponding side panel 130 and integrally formed, the first abutting part 311 is located above the second abutting part 312, and the width of the first abutting part 311 is smaller than that of the second abutting part 312. When viewed in the horizontal direction, the adhesive insert plate 310 is in the shape of “convex”. The first abutting part 311 and the second abutting part 312 near the side of the forming mold 100 are both provided with a flexible extrusion part 320 in the shape of a plane. And the thickness of the flexible extrusion part 320 is in the range of 10-30mm.

[0078] It should be noted that when the forming die 100 presses and stamps the sheet 700 into a "U" shape, the side edge 710, the edge 720 and the rubberized edge 730 of the sheet 700 are located on one side of the side panel 130 of the forming die 100, and the edge 720 is adsorbed by the adsorption hole of the side edge 710 of the forming die 100 and is attached to the side panel 130, when the adhesive insert plate 310 pushes the side edge 710 of the sheet 700, the first abutting portion 311 corresponds to the position where the rubberized edge 730 of the side edge 710 of the sheet 700 is pushed, therefore the first abutting portion 311 is provided to be long but narrow in width, the second abutting portion 312 corresponds to the position where the side edge 710 and the edge 720 of the sheet 700 are pushed and abutted, and ensures that the edge 720 of the sheet 700 is located inside the side edge 710 each time it is formed, therefore the abutting area of the second abutting portion 312 is larger, and the width of the second abutting portion 312 is greater than that of the first abutting portion 311. Finally, the adhesive insert plate 310 is in the shape of "convex", which not only reduces the material, but also can ensure that the side edge 710 of the sheet 700 is pressed well.

[0079] The thickness of the flexible extrusion portion 320 can be 10mm, 15mm, 20mm, 30mm or any value within the range of 10-30mm, which is not limited in the utility model.

[0080] Further preferably, in the side insertion structure 300 of the bag forming machine disclosed by the utility model, the material of the flexible extrusion portion 320 comprises any one of rubber, foam, foam, polyvinyl alcohol and polyester fiber.

[0081] By adopting the above technical scheme, the flexible extrusion portion 320 is preferably made of flexible and elastic material, for example, when it is made of rubber material, it has good elasticity and damping effect, can effectively absorb and disperse stress, is resistant to wear and corrosion, is suitable for various harsh environments, and has strong plasticity and is easy to process into various shapes and sizes. For example, when it is made of foam or foam material, it has the advantages of light weight, easy carrying and installation, good sound absorption and damping performance, and good heat preservation and insulation performance. For example, when it is made of polyvinyl alcohol or polyester fiber, it has high strength and toughness, can withstand greater pressure, and has good wear resistance and chemical corrosion resistance. In summary, the material selection of the flexible extrusion portion 320 can be considered comprehensively according to the specific application scene and requirements. Different materials have different properties and characteristics, and selecting appropriate materials can ensure that the flexible extrusion portion 320 has excellent performance, stability and durability.

[0082] Further preferably, in the side insertion structure 300 of the bag forming machine disclosed by the utility model, please see Figure 3 and 4The side of the auxiliary pushing part 330 away from the bonding plug-in plate 310 is provided with an auxiliary pushing part 330. The auxiliary pushing part 330 comprises a pushing plate 332, the pushing plate 332 is further provided with a weight-reducing hole 331, and the pushing plate 332 comprises two parts, one part is located at the upper part and connected with the first abutting part 311, and the other part is located at the lower part and connected with the second abutting part 312. The part of the pushing plate 332 close to the first abutting part 311 is in a trapezoidal shape, the part away from the first abutting part 311 is in a square shape, and the middle is further provided with a square and circular weight-reducing hole 331.

[0083] And referring to Figure 3 The side of the auxiliary pushing part 330 away from the bonding plug-in plate 310 is further provided with an adjusting guide rail 333, and the position of the bonding plug-in plate 310 can be adjusted through the adjusting guide rail 333.

[0084] In another embodiment of the utility model, the auxiliary pushing part 330 is plate-shaped, is arranged opposite to the bonding plug-in plate 310 and has a plurality of elastic members between the auxiliary pushing part 330 and the bonding plug-in plate 310. Wherein, one end of each elastic member is connected with the auxiliary pushing part 330, and the other end is connected with the side of the bonding plug-in plate 310 away from the forming die 100. For example, the elastic member can be a spring, and the spring can be uniformly and spacedly arranged in three, four, five, six or even more numbers. The embodiment does not make specific limitation to this, and it needs to be explained that the plurality of elastic members can also play the same role as the flexible extruding part 320. When the bonding plug-in plate 310 pushes the side edge 710 of the sheet material 700 and contacts the side panel 130 of the forming die 100, elastic contact is first carried out to avoid rigid impact, and when the pushing force is continuously provided, the elastic member will be elastically deformed, and the bonding plug-in plate 310 and the side panel 130 are more closely abutted, so that the bonding of the side edge 710 of the sheet material 700 is more firm.

[0085] Next, the specific structure of the driving mechanism 340 of the side plug-in structure 300 of the bag body forming machine disclosed in the embodiment will be described:

[0086] In a preferred implementation, the driving mechanism 340 comprises a driving motor 341, a rotating wheel 342, a transmission connecting rod 343 and an auxiliary pushing part 330. The driving motor 341 is located on the outer side of the bonding plug-in plate 310 away from the forming die 100. The rotating wheel 342 is rotatably connected with the driving motor 341. One end of the transmission connecting rod 343 is movably connected with the part close to the circumferential edge of the rotating wheel 342, and the other end is movably connected with the auxiliary pushing part 330. The side of the auxiliary pushing part 330 away from the transmission connecting rod 343 is fixedly connected with the bonding plug-in plate 310. When the driving motor 341 drives the rotating wheel 342 to rotate, the transmission connecting rod 343 can drive the auxiliary pushing part 330 and the bonding plug-in plate 310 to reciprocate relative to the forming die 100.

[0087] With the above structure, the driving motor 341, the rotating wheel 342, the transmission connecting rod 343 and the auxiliary pushing part 330 actually form a crank slider mechanism. With such a structure, the driving motor 341 only needs to drive the rotating wheel 342 to rotate continuously in one direction, and the transmission connecting rod 343 will drive the auxiliary pushing part 330 to slide reciprocatingly continuously, so that the rotation of the motor is finally converted into the movement of the auxiliary pushing part 330. This has the advantages of high movement stability, small vibration and impact during operation, and can improve mechanical efficiency, enhance structural strength and simplify mechanical structure.

[0088] It should be noted that the driving mechanism 340 can also adopt other forms, for example, it can be a driving motor 341 plus a gear and rack mechanism, the driving motor 341 drives the gear, the gear drives the rack to move reciprocatingly, and the rack drives the bonded insert plate 310 to move reciprocatingly. It can also be a driving motor 341 plus a lead screw and slider mechanism, in which the motor drives the lead screw to rotate reciprocatingly, and the slider moves reciprocatingly along the lead screw, so that the bonded insert plate 310 can also move reciprocatingly. Those skilled in the art can also set other driving structures, which will not be described here in detail.

[0089] Further preferably, the auxiliary pushing part 330 is provided at the bottom with a moving seat 344 and a guide slide rail 345, the guide slide rail 345 is arranged in the horizontal direction and has the same extension direction as the movement direction of the bonded insert plate 310; and the length dimension of the guide slide rail 345 is greater than the movement dimension of the bonded insert plate 310.

[0090] With such a structure, the moving seat 344 and the guide slide rail 345 can play a guiding and auxiliary moving role. Since the friction between the moving seat 344 and the guide slide rail 345 is small, the energy loss is reduced. Further, the length dimension of the guide slide rail 345 is greater than the movement dimension of the bonded insert plate 310, and preferably the length dimension of the guide slide rail 345 is less than the thickness dimension of the flexible extrusion part 320, so as to avoid excessive rigid impact.

[0091] Specifically, for example, when the thickness dimension of the flexible extrusion part 320 is 30 mm, the length dimension of the guide slide rail 345 can be set to be greater than the movement dimension of the bonded insert plate 310 by 15 mm, 20 mm or 25 mm, but not more than 30 mm. If the length dimension of the guide slide rail 345 exceeds 30 mm, the bonded insert plate 310 will contact and bond with the bonding part 160 of the side edge 710 of the forming mold 100 when the flexible extrusion part 320 is pushed, which will cause excessive travel and rigid impact, damaging the side edge 710 of the forming mold 100 or the bonded insert plate 310.

[0092] In another preferred implementation not shown in the drawings, the adhesion plug-in plate 310 is further provided with a driving mechanism 340 on the side away from the bag body forming chamber 201, the driving mechanism 340 comprising a driving cylinder, a driving rod and an auxiliary pushing part 330. The driving cylinder is located on the outer side of the adhesion plug-in plate 310 away from the forming mold 100, the power output end of the driving cylinder is fixedly connected with the driving rod, and the auxiliary pushing part 330 is fixedly arranged on the outer surface of the adhesion plug-in plate 310 and fixedly connected with the end of the driving rod away from the driving cylinder. Moreover, the auxiliary pushing part 330 is provided with a moving seat 344 and a guide slide rail 345 at the bottom, the guide slide rail 345 is arranged along the horizontal direction and has the same extending direction as the moving direction of the adhesion plug-in plate 310.

[0093] With the above structure, the driving cylinder can drive the adhesion plug-in plate 310 to reciprocate, which has the advantages of simple structure and convenient control.

[0094] The embodiment also discloses a side plug-in structure 300 of a bag body forming machine, and the two sides of the forming mold 100 are symmetrically provided with a pair of adhesion plug-in plates 310, which correspond to the two side panels 130 of the forming mold 100 respectively. Moreover, the outer side of each adhesion plug-in plate 310 away from the forming mold 100 is provided with a driving mechanism 340.

[0095] With the above structure, the two sides of the forming mold 100 are symmetrically provided with a pair of adhesion plug-in plates 310, which can stamp and press the side edge 710 of the two side portions of the bag body. In the foregoing embodiment, one side of the bag body forming machine is provided with one plug-in structure, and one adhesion plug-in plate 310 on one side can stamp one side portion of the bag body or the sheet material 700, which can meet the requirement of stamping only one side of the packaging bag.

[0096] Next, the side plug-in plate 400 of the side plug-in structure 300 of the bag body forming machine is described in detail.

[0100] When the sheet material 700 is pressed by the forming die 100 and enters the bag body forming cavity 201 to form a "U" shape, the two side inserting plates 400 translate and push the side edge 710 of the sheet material 700 to fold the side edge 710 of the sheet material 700 towards one side of the side panel 130 of the forming die 100 and bond together through the extrusion of the bonding inserting plate 310 and the side panel 130.

[0101] With the structure, the two side inserting plates 400 can first push the side edge 710 of the sheet material 700 to fold towards one side of the side panel 130 of the forming die 100, and finally bond together through the extrusion of the bonding inserting plate 310 and the side panel 130, so that the forming rate of the bag body is improved.

[0102] The embodiment of the utility model discloses a side inserting structure 300 of bag body forming machine, one side of side inserting plate 400 is provided with side inserting drive mechanism, and side inserting drive mechanism drives side inserting plate 400 to reciprocate in the gap between bonding inserting plate 310 and forming die 100.

[0105] In summary, the utility model discloses a kind of side insertion structure 300 of bag body forming machine, first, the side panel 130 of the forming mold 100 of the present application has the bonding effect part 160 opposite to the side of bag body The bonding part 160 is used to provide bonding plane to the side of sheet material 700, and can provide bonding site or bonding effect plane for bag body of different size and different volume.
