[0022] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-4This embodiment provides an automatic packaging machine 1, comprising a material storage and feeding assembly 10, a bag cutting assembly 20, a bag pulling assembly 30, a bag moving assembly 40, and a machine platform 50. The bag pulling assembly 30 and the bag moving assembly 40 are mounted on the machine platform 50. The bag pulling assembly 30 and the bag moving assembly 40 constitute a bag transfer module of this embodiment.

[0025] The material storage and feeding assembly 10 is used to store and convey the material bags 11. The automatic packaging machine 1 is used to package products using the material bags 11 as packaging materials. The material bags 21 are two-layer film structures, which are formed by folding a single layer of film along the center line.

[0026] The bag 11 is heat-severed and sealed at its first edge by the bag cutting assembly 20. The bag pulling assembly 30 then grips and hooks the first edge, pulling the bag 11 to the desired length. The bag cutting assembly 20 then heat-severes and seals the second edge, forming a packaging bag of the desired size. The bag now has a single-sided opening. The bag is then gripped by the bag handling assembly 40, transporting the bag to the next process for subsequent product packaging.

[0027] The bag pulling assembly 30 includes a first clamping assembly 31, a second clamping assembly 32, a hook and pull assembly 33, a longitudinal translation slide 35, a longitudinal mounting plate 36, a horizontal transverse slide 34 and a power assembly 37. The first clamping assembly 31, the second clamping assembly 32 and the hook and pull assembly 33 are all installed on the longitudinal translation slide 35 in an adjustable manner. Therefore, the longitudinal position of the first clamping assembly 31, the second clamping assembly 32 and the hook and pull assembly 33 is adjustable and can be adapted to bags of different specifications.

[0028] The first clamping assembly 31 includes a first clamping jaw 311 and a first clamping jaw mounting base 312. The second clamping assembly 32 includes a second clamping jaw 321, a clamping jaw lifting cylinder 322, and a second clamping jaw mounting base 323. The hooking and pulling assembly 33 includes a hook 331, a hook lifting cylinder 332, and a hook mounting base 333. The first clamping jaw 311 and the second clamping jaw 321 are used to clamp the bag edge and also pull the bag. The hook 331 is used to hook and pull the bag edge. The first clamping jaw 311, the second clamping jaw 321, and the hook 331 cooperate to continuously pull the bag out of the material storage and feeding assembly 10. This has a simple structure and is easy to operate.

[0029] The first clamping jaw 311 is mounted on the first clamping jaw mounting base 312, the second clamping jaw 321 is mounted on the second clamping jaw mounting base 323 via a clamping jaw lifting cylinder 322, and the hook member 331 is mounted on the hook member mounting base 333 via a hook member lifting cylinder 332. The first clamping jaw mounting base 312, the second clamping jaw mounting base 323, and the hook member mounting base 333 are all mounted on the longitudinal translation rail 35 in an adjustable manner. Thus, the longitudinal positions of the first clamping jaw 311, the second clamping jaw 321, and the hook member 331 are adjustable, allowing them to accommodate bags of different sizes.

[0030] The first clamping jaw mounting seat 312, the second clamping jaw mounting seat 323, and the hook member mounting seat 333 are all provided with a locking structure. For example, the first clamping jaw mounting seat 312 has a locking screw 3121. The locking structure can lock the first clamping jaw mounting seat 312, the second clamping jaw mounting seat 323, and the hook member mounting seat 333 in the position of the longitudinal translation slide rail 35.

[0031] The longitudinal translation rail 35 is mounted on a longitudinal mounting plate 36, which is laterally displaceably mounted on two horizontal transverse rails 34. A power assembly 37 is connected to the longitudinal mounting plate 36, thereby driving the longitudinal mounting plate 36 to move laterally. This in turn drives the first clamping jaw 311, the second clamping jaw 321, and the hook member 331 to move laterally, thereby pulling the material bag out of the material storage and feeding assembly 10. This provides good operational synchronization and a simple and reliable structure.

[0032] The bag moving assembly 40 is arranged in a direction facing the bag opening and includes two sets of bag moving clamping mechanisms, each set of bag moving clamping mechanisms including an upper bag moving clamping mechanism 410 and a lower bag moving clamping mechanism 420 .

[0033] The upper bag-handling clamping mechanism 410 includes an upper claw 411, an upper pressure block 412, an upper cylinder 413, and an upper mounting base 414. The lower bag-handling clamping mechanism 420 includes a lower claw 421, a lower extension block 422, a lower cylinder 423, a lower mounting base 424, and a lower pressure block 425. The upper cylinder 413 is mounted on the upper mounting base 414 and is connected downwardly to the upper pressure block 412. The upper claw 411 is located directly below the upper pressure block 412. The lower cylinder 423 is mounted on the lower mounting base 424. The lower extension block 422 is an L-shaped structure. The lower cylinder 423 is connected to one end of the lower extension block 422, and the other end of the lower extension block 422 is connected to the lower pressure block 425. The lower claw 421 is located directly above the lower pressure block 425. The upper claw 411 and the lower claw 421 are arranged opposite and aligned. The bag moving assembly 40 also includes a bag moving power component 43, which includes a bag moving lateral displacement component 431 and a bag moving longitudinal displacement component (not shown), so that the upper mounting seat 414 and the lower mounting seat 424 can be mounted on the machine 50 in a longitudinal and transverse displacement manner; the bag moving lateral displacement component 431 is, for example, a motor belt drive structure.

[0034] After the bag pulling assembly 30 pulls out the packaging bag and completes bag making, the bag moving assembly 40 is displaced longitudinally, and the upper claw 411 and the lower claw 421 of the bag moving assembly 40 are inserted into the bag opening. The upper claw 411 and the lower claw 421 are located between the two layers of film of the packaging bag. The upper cylinder 413 and the lower cylinder 423 respectively push the upper pressure block 412 and the lower pressure block 425 to compress the two layers of film of the packaging bag. Thereafter, the first clamping jaw 311 and the second clamping jaw 321 are released, and the hook member 331 is simultaneously separated from the bag opening. The piston rods of the clamping jaw lifting cylinder 322 and the hook member lifting cylinder 332 are retracted, and the second clamping jaw 321 and the hook member 331 are lowered. The bag pulling assembly 30 also includes two laterally parallel support rods 38, and the two laterally parallel support rods 38 are arranged on the machine platform 50. The second clamping jaw 321 and the hook member 331 can be lowered to below the support rod 38 through the clamping jaw lifting cylinder 322 and the hook member lifting cylinder 332 respectively, so that the support rod 38 lifts the packaging bag upward, which is conducive to the bag moving assembly 40 to drive the packaging bag to move horizontally more smoothly, thereby moving the packaging bag to the next workstation.

[0035] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
