[0050] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0051] like Figures 1 to 4 As shown, an embodiment of this application provides a material-fixing and flange-flanging mechanism for a bag-opening machine, which includes a material-fixing component and a pressing component. It is understood that the material-fixing component and the pressing component can be mounted on the overall frame of the bag-opening machine.

[0052] The material positioning assembly includes: a base 101, a limiting plate disposed on the base 101, a first driving member disposed on the base 101 for driving the limiting plate to move horizontally, an auxiliary plate disposed on the base 101 below the limiting plate, a second driving member disposed on the base 101 for driving the auxiliary plate to move horizontally, a panel 110 disposed on the base 101 above the limiting plate, a first lifting assembly 111 disposed on the base 101, and a pressure frame 1125 assembly 112 connected to the first lifting assembly 111 and located above the panel 110. The first lifting assembly 111 may consist of a cylinder, a lifting platform 1111 connected to the cylinder and mounted on a guide rail, and a support arm 1112 connected to the lifting platform 1111. The support arm 1112 is connected to the pressure frame 1125 assembly 112. The base 101 is provided with a rectangular slot 1011, and the panel 110 is provided with an opening corresponding to the slot 1011. There are four limiting plates arranged circumferentially around the slot 1011. The four limiting plates include two long-side limiting plates 102 and two short-side limiting plates 103. Each limiting plate is equipped with a first driving component. There are also four auxiliary plates arranged circumferentially around the slot 1011. The four auxiliary plates include two long-side auxiliary plates 104 and two short-side auxiliary plates 105. Each auxiliary plate is equipped with a second driving component. The four auxiliary plates correspond one-to-one with the four limiting plates. The first driving component includes a first linear slide rail 106 and a first cylinder 107. The limiting plate is set on the first linear slide rail 106 and connected to the first cylinder 107. The second driving component includes a second linear slide rail 108 and a second cylinder 109. The auxiliary plate is set on the second linear slide rail 108 and connected to the second cylinder 109. The pressing head 220 assembly includes a second lifting assembly 210 and a pressing head 220 connected to the second lifting assembly 210.

[0053] Specifically, this application includes four limiting plates and four auxiliary plates. Each limiting plate is equipped with an independent driving component, which is located on the outer side of the limiting plate. A first cylinder 107 drives the corresponding limiting plate to move linearly along its corresponding first linear slide rail 106. Each auxiliary plate is also equipped with an independent driving component, located on its outer side. A second cylinder 109 drives the corresponding auxiliary plate to move linearly along its corresponding second linear slide rail 108. Because the limiting plates and auxiliary plates are not interconnected and are driven by their own independent driving components, any malfunction can be detected promptly. Only the faulty auxiliary plate or limiting plate, or the corresponding driving component, needs to be replaced.

[0054] Based on the above, in one embodiment, such as Figure 8 and Figure 4As shown, the limiting plate corresponding to the short side of the slot 1011 includes a first extension 1031 and a first limiting part 1032. The first extension 1031 is connected to two first cylinders 107. The auxiliary plate corresponding to the short side of the slot 1011 includes a second extension 1051 and a first auxiliary part 1052. The second extension 1051 is connected to two second cylinders 109. The auxiliary plate corresponding to the long side of the slot 1011 includes a third extension 1041 and a second auxiliary part 1042. The third extension 1041 is connected to two second cylinders 109. The limiting plate corresponding to the long side of the slot 1011 includes a fourth extension 1021 and a second limiting part 1022. The fourth extension 1021 is connected to one first cylinder 107 through a transmission component.

[0055] In one embodiment, such as Figure 2 As shown, the second lifting assembly 210 includes a bracket 216, a lifting motor 211 mounted on the bracket 216, a drive gear 212 connected to the lifting motor 211, a rack 213 meshing with the drive gear 212, and a first lifting plate 214 connected to the rack 213. The first lifting plate 214 is mounted on a first vertical guide rail assembly. A second lifting plate 215 is provided on one side of the first lifting plate 214. The second lifting plate 215 is mounted on a second vertical guide rail assembly. Both the first vertical guide rail assembly and the second vertical guide rail assembly are mounted on the bracket 216.

[0056] Specifically, the lifting motor 211 drives the aforementioned drive gear 212 to rotate, the drive gear 212 drives the rack 213 to move up and down, and the rack 213 drives the first lifting plate 214 to move up and down. The pressing head 220 generally includes a support frame 221, which is connected to the first lifting plate 214 and the second lifting plate 215 respectively. The up and down movement of the first lifting plate 214 will also drive the support frame 221 and the second lifting plate 215 to move up and down together.

[0057] In one embodiment, such as Figures 2 to 4As shown, the pressing head 220 includes a support frame 221 connected to the first lifting plate 214 and the second lifting plate 215, an intermediate block 222 disposed below the support frame 221 and connected to the support frame 221, and insert plate driving cylinders 223 disposed on both sides of the intermediate block 222 and connected to the support frame 221. Each insert plate driving cylinder 223 is connected to a short side insert plate 224. Long side insert plates 225 are respectively disposed on both sides of the lower end of the intermediate block 222. The four auxiliary plates include two oppositely disposed short side auxiliary plates 105 and two oppositely disposed long side auxiliary plates 104. The two short side auxiliary plates 105 correspond one-to-one with the two short side insert plates 224, and the two long side auxiliary plates 104 correspond one-to-one with the two insert plates. The short side auxiliary plates 105 are provided with a slit for the short side of the bag opening to be inserted, and the long side auxiliary plates 104 are provided with a slit for the long side of the bag opening to be inserted.

[0058] The above describes the first embodiment of the pressing head 220. In this embodiment, the pressing head 220 is equipped with two short-side insert plates 224 and two long-side insert plates 225. First, the two short-side insert plates 224 are retracted under the action of the insert plate drive cylinder 223. Then, the pressing head 220 descends, pressing the two long sides of the bag opening into the gaps 400 of the corresponding long-side auxiliary plates 104 below through the two long-side insert plates 225. Then, the pressing head 220 rises, and the short-side insert plates 224 extend under the action of the insert plate drive cylinder 223. Then, the pressing head 220 descends, pressing the two short sides of the bag opening into the gaps 400 of the corresponding short-side auxiliary plates 105 below through the two short-side insert plates 224. Next, the pressing head 220 rises and resets, and the long side auxiliary plate 104 and the short side auxiliary plate 105 move laterally under the action of their respective driving components, so that the long side and short plate of the bag opening can be folded and positioned.

[0059] The following is a second embodiment of the pressure head 220. In one embodiment, such as Figure 5 and Figure 6As shown, the pressing head 220 includes a support frame 221 and an intermediate block 222 disposed below and connected to the support frame 221. The intermediate block 222 is used to open the long and short sides of the pocket downwards. The four auxiliary plates include two oppositely arranged short side auxiliary plates 105 and two oppositely arranged long side auxiliary plates 104. The short side auxiliary plates 105 are used to cooperate with the corresponding limiting plates to clamp and position the short side of the folded pocket. The long side auxiliary plates 104 are used to cooperate with the corresponding limiting plates to clamp and position the long side of the folded pocket. In addition to the above, a folding mechanism 300 disposed below the auxiliary plates is also included. The folding mechanism 300 includes: a base 301, a first lead screw drive assembly 302, two X-direction material pushing plates 303, and a main lifting mechanism 304. The main lifting mechanism 304 may be a lead screw mechanism, etc. The first lead screw drive assembly 302 is mounted on the base 301. Two X-axis material-pushing plates 303 are mounted on the first lead screw drive assembly 302. The two X-axis material-pushing plates 303 move closer or further apart synchronously. The main lifting mechanism 304 is connected to the base 301 and is used to drive the base 301 to rise or fall. A first bracket 305 and a second bracket 306 are respectively mounted on both sides of the base 301. The first bracket 305 is equipped with a first lifting mechanism 311, which can be a cylinder or similar mechanism. The second bracket 306 is equipped with a second lifting mechanism 312, which can also be a cylinder or similar mechanism. It also includes a first Y-axis material-pushing plate 308 and a second Y-axis material-pushing plate 310. The first Y-axis material-pushing plate 308 is mounted on a first Y-axis lead screw drive assembly 307, which is driven by a first lifting mechanism 311 for lifting and lowering. Specifically, the first Y-axis lead screw drive assembly 307 can be mounted on a platform, and the first lifting mechanism 311 is connected to the platform. Similarly, the second Y-axis material-pushing plate 310 is mounted on a second Y-axis lead screw drive assembly 309, which is driven by a second lifting mechanism 312 for lifting and lowering.

[0060] Specifically, in the second embodiment of the aforementioned pressing head 220, after the pressing head 220 descends, it can fold the long and short sides of the bag opening, which are in a horizontal state, downwards at a certain angle. Then, the main lifting mechanism 304 of the folding mechanism 300 rises, and the two long sides of the bag opening are folded outwards by two X-direction material pushing plates 303. Next, the two short sides of the bag opening are folded outwards by two Y-direction material pushing plates. Then, the auxiliary plates extend, and the long and short sides of the bag opening can be supported by the corresponding auxiliary plates, that is, the long and short sides are clamped between the corresponding auxiliary plates and the limiting plates. Then, the main lifting mechanism 304 of the folding mechanism 300 descends, and the X-direction material pushing plates and Y-direction material pushing plates reset.

[0061] The first lifting mechanism 311 and the second lifting mechanism 312 are designed to prevent interference between the Y-direction material pusher plate and the X-direction material pusher plate 303.

[0062] Based on the above, in one embodiment, such as Figure 8 and Figure 9 As shown, the end of the short-side auxiliary plate 105 is provided with multiple insert teeth 1041, and the end of the long-side auxiliary plate 104 is also provided with multiple insert teeth 1041. Correspondingly, the top of the X-direction feeding push plate 303 and the top of the Y-direction feeding push plate are both provided with multiple feeding teeth 313. The insert teeth 1041 can be inserted into the gap between two feeding teeth 313.

[0063] In one embodiment, such as Figure 7 As shown, the pressure frame 1125 assembly 112 includes a pressure frame 1125, two oppositely arranged long side pressure strips 1121, and two oppositely arranged short side pressure strips 1122. The ends of the long side pressure strips 1121 and the short side pressure strips 1122 are provided with pressure teeth. The long side pressure strips 1121 and the short side pressure strips 1122 are mounted on the pressure frame 1125 through a hinge structure. The pressure frame 1125 is provided with four cylinder mounting brackets 1126. Each cylinder mounting bracket 1126 is hinged to a pressure strip driving cylinder 1123. The long side pressure strips 1121 are hinged to the adjacent pressure strip driving cylinders 1123, and the short side pressure strips 1122 are hinged to the adjacent pressure strip driving cylinders 1123. Both the long side pressure strips 1121 and the short side pressure strips 1122 are used to press the fabric.

[0064] Specifically, the pressure frame 1125 of the pressure frame 1125 assembly 112 can be connected to the support arm 1112 of the first lifting assembly 111.

[0065] This application allows for adjustment of the pressure of the corresponding pressure strip by adjusting the air pressure of the pressure strip drive cylinder 1123. This facilitates flexible adjustment of the pressure value according to different fabric specifications. It helps protect the fabric from damage and also ensures reliable pressing of fabrics of different specifications.

[0066] In one embodiment, the long side pressure strip 1121 includes a long side L-shaped main body, and the ends of the long side L-shaped main body are provided with toothed structures. The short side pressure strip 1122 includes a short side L-shaped main body, and the ends of the short side L-shaped main body are provided with toothed structures.

[0067] In one embodiment, such as Figure 1 As shown, it also includes a housing 113 connected to the base 101, with the first and second driving members located inside the housing 113. The housing 113 helps to protect the internal driving members.

[0068] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
