[0002] With the development of the times, the application of packaging materials is becoming more and more extensive. As a new type of environmentally friendly packaging material, pearl cotton has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It is an ideal substitute for traditional packaging materials.

[0003] In the deep processing of pearl cotton, one of the pearl cotton is usually partially heated and melted by electric blowing or electric heating plate, and then the two pieces of pearl cotton are bonded. The above bonding method, whether using an automatic bonding machine or manual bonding, has the following problems: of the two pieces of pearl cotton to be bonded, only one is in a heated and melted state, and the other is in a normal state without preheating. In this state, the heated pearl cotton needs to melt more material to firmly bond the two, which not only increases the heating time, but also one of the pearl cotton is burned more, seriously affecting the bonding quality and effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0029] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments describe the present invention in detail.

[0030] The utility model provides a packaging material forming machine for bonding two upper and lower packaging materials. The packaging materials include but are not limited to pearl cotton, foam cotton, etc. The specific embodiment of the application is described by taking bonding two pieces of pearl cotton as an example.

[0031] See also Figures 1 to 5 The packaging material forming machine of the present application includes a machine table 1, a feeding device 2, a material taking device 3 and a hot plate device 4. The hot plate device 4 moves horizontally above the feeding device 2, and is used to heat and melt one of the pearl cotton sheets on the feeding device 2, and preheat the other pearl cotton sheet; the material taking device 3 moves up and down above the feeding device 2, and is used to extract the upper pearl cotton sheet from the feeding device 2, and press and bond the two pearl cotton sheets; the feeding device 2 includes a lifting component 21 arranged on the machine table 1 and a conveying component 22 fixed on the lifting end of the lifting component 21, and the conveying component 22 is used to convey the pearl cotton material, such as conveying the pearl cotton to be processed to the bottom of the material taking device 3, or conveying the pearl cotton after processing to the outside of the equipment; the lifting component 21 is used to drive the conveying component 22 to move up and down, and change the vertical distance between the hot plate device 4 and the conveying component 22. For example, in one embodiment, after the material taking device 3 takes away the upper piece of pearl cotton on the conveying component 22, the ironing board device 4 moves to the top of the conveying component 22. At the same time, the conveying component 22 moves upward to a preset position, so that the vertical distance between the conveying component 22 and the ironing board device 4 is shorter, and the material taking device 3 descends to place the upper piece of pearl cotton on the ironing board device 4. At this time, while the upper piece of pearl cotton is heated on the ironing board device 4, the lower piece of pearl cotton is preheated. Since the lower piece of pearl cotton is preheated before bonding, the time for the upper piece of pearl cotton to be heated, melted and softened can be appropriately shortened to reduce the depth of melting, thereby further improving the bonding quality of the packaging material.

[0032] In a preferred embodiment, Figure 5As shown, the ironing plate device 4 of the present application includes a hot plate 41, and the hot plate 41 is a double-sided hot plate, that is, the hot plate 41 can heat and melt the upper piece of pearl cotton while preheating the lower piece of pearl cotton, and can also heat and melt the lower piece of pearl cotton while preheating the upper piece of pearl cotton; when the material taking device 3 takes away the upper piece of pearl cotton on the conveying component 22, the hot plate device 4 moves to the top of the conveying component 22, and at the same time, the conveying component 22 moves upward so that the lower piece of pearl cotton on it contacts the hot plate, and at the same time, the material taking device 3 descends to shorten the distance between the upper piece of pearl cotton and the hot plate 41. At this time, the upper piece of pearl cotton is preheated while the lower piece of pearl cotton is heated on the hot plate 41. Since the upper piece of pearl cotton is preheated before bonding, the time for the lower piece of pearl cotton to be heated, melted and softened can be appropriately shortened to reduce the depth of melting, thereby further improving the bonding quality of the packaging material.

[0033] It is worth emphasizing again that when the materials or structures of the upper and lower pearl cotton are different, the material taking device 3 can be controlled to descend a certain distance according to actual needs so that the upper pearl cotton contacts the upper surface of the hot plate 41, and the upper pearl cotton is heated and melted; or the conveying component 22 can be controlled to rise a certain distance so that the lower pearl cotton contacts the lower surface of the hot plate 41, and the lower pearl cotton is heated and melted. The arrangement of the above structure expands the scope of application of the molding machine of the present application.

[0034] Specifically, the conveying component 22 of the embodiment of the present application is a belt conveying component, which realizes the conveyance of materials through a belt. The specific structure of the belt conveying component can be designed according to the existing technology and is not specifically introduced in this application.

[0035] For details, see Figure 1 and Figure 2 The conveying direction of the conveying component 22 is the same as or perpendicular to the moving direction of the ironing board device 4. When designing specifically, those skilled in the art may consider reducing the overall size of the equipment and saving costs, as long as the distance of the utility model can be achieved.

[0036] For details, see Figure 3 , Figure 4, the lifting assembly 21 includes a mounting plate 211 arranged on the machine 1, a nut seat 212 rotatably arranged on the mounting plate 211, and a screw rod 213 threadedly connected to the nut seat 212; the upper end of the screw rod 213 is connected to the lifting plate 214, and the lower end of the screw rod 213 passes through the mounting plate 211 and extends downward. When the nut seat 212 rotates, it can drive the screw rod 213 matched therewith to move up and down, thereby driving the lifting plate 214 to move up and down. Since the transmission assembly 22 is fixedly connected to the lifting plate 214, the up and down movement of the transmission assembly 22 is realized. In this embodiment, the cooperation of the nut seat 212 and the screw rod 213 is used to realize the lifting of the transmission assembly 22, which has the advantages of high precision and high efficiency. It can be understood that all lifting assemblies 21 that can realize the lifting function of the transmission assembly 22 in this application belong to the protection scope of the utility model, and the lifting assembly 21 shown in the figure is only one of the embodiments, but it is not limited to this.

[0037] Specifically, there are multiple nut seats 212 in the embodiment of the present application, and they are arranged on the outer edge of the mounting plate 211. Each nut seat 212 is provided with a synchronous wheel 215, and multiple synchronous wheels 215 are provided with a synchronous belt 216. As long as one of the nut seats 212 is driven to rotate, all the nut seats 212 can be driven to rotate synchronously, thereby realizing the lifting function of the lifting plate 214. For example, the mounting plate 211 and the lifting plate 214 are both square plates, and the nut seats 212 are arranged at the four corners of the square plate, so as to achieve a uniform support effect on the transmission component 22.

[0038] Specifically, the synchronous rotation of the nut seat 212 is driven by a first driving assembly, which includes a first motor 231 fixed on the mounting plate 211 and a driving wheel 232 installed on the first motor 231. The synchronous belt 216 is wound around the driving wheel 232 and the synchronous wheel 215. In other words, the driving wheel 232 drives the synchronous belt 216 to rotate, and then drives all the synchronous wheels 216 to rotate. Since the synchronous wheel 216 is fixedly mounted on the nut seat 212, the synchronous rotation of all the nut seats 212 is achieved.

[0039] Specifically, a guide sleeve 217 is provided on the side of each nut seat 212 of the embodiment of the present application, and a guide shaft 218 parallel to the screw rod 213 is provided in the guide sleeve 217, and the upper end of the guide shaft 218 is connected to the lifting plate 214, and the lower end of the guide shaft 218 extends downward after passing through the mounting plate 211. The guide sleeve 217 and the guide shaft 218 guide the lifting and lowering of the lifting plate 214, so as to prevent the nut seat 212 from being deflected by force during the rotation process, which causes the lifting plate 214 to be deflected, and finally affects the transmission stability and balance of the transmission assembly 22, and indirectly affects the bonding quality.

[0040] In a preferred embodiment, at least one tensioning wheel 219 is also provided inside the synchronous belt 216. The tensioning wheel 219 is rotatably provided on the fixed shaft. A movable groove corresponding to the tensioning wheel 219 is provided on the mounting plate 211. The lower end of the fixed shaft is movably provided in the movable groove. The movable groove is a strip groove. The lower end of the fixed shaft is slidably provided in the strip groove and is detachably fixed in the strip groove by a fixing member. The tensioning force of the synchronous belt 216 will decrease during long-term use, causing the synchronous belt 216 to become loose. The present application provides a movable tensioning wheel 219, which can be adjusted at any time according to the use of the synchronous belt 216, thereby ensuring the synchronous rotation of all nut seats 212 and keeping the transmission assembly 22 in a horizontal state at all times, thereby ensuring that the pearl cotton has a high bonding quality.

[0041] Specifically, there are at least two feeding devices 2 and material taking devices 3 , which are arranged in one-to-one correspondence; there is at least one ironing plate device 4 , which moves below at least two material taking devices 3 .

[0042] In an optional embodiment, Figure 1 As shown, the molding machine is a single-station molding machine, and there is one material taking device 3, one feeding device 2 and one ironing device 4 respectively, and the moving directions of the feeding device 2 and the ironing device 4 are consistent. It can be understood that in other embodiments, the moving directions of the feeding device 2 and the ironing device 4 can also be different, as long as the pearl cotton can be moved to the bottom of the material taking device 3, it falls within the protection scope of the present utility model.

[0043] like Figure 2 As shown, in another optional embodiment, the forming machine is a double-station forming machine, and there are two feeding devices 2 and two picking devices 3 respectively, the two feeding devices 2 are arranged in parallel, and the two picking devices 3 are arranged above the two feeding devices 2 respectively; there is one ironing device 4, which reciprocates below the two picking devices 3, that is, the feeding device 2 and the ironing device 4 have different moving directions, and the ironing device 4 is arranged between the two picking devices 3, and reciprocates below the two picking devices 3. In this embodiment, the ironing device 4 is arranged as one, which not only reduces the volume of the equipment, but also saves the equipment cost, which is more conducive to the promotion of the equipment. It can be understood that in other embodiments, the ironing device 4 can also be designed as two, as long as the two ironing devices 4 can be moved to the bottom of the two picking devices 3 respectively, it falls within the protection scope of the present utility model.

[0044] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
