Description

[Technical field]

[0001] The invention belongs to the technical field of automatic packaging, and in particular relates to an automatic sealing and feeding mechanism for packaging bags. [Background technology]

[0002] The research and development of packaging automation equipment has always been an important means to improve production efficiency in the packaging industry. Most of the automatic packaging and sealing equipment in the existing technology adopts linear or rotary assembly line operation to achieve automatic sealing and discharging. However, whether it is a linear or rotary assembly line operation, it can only seal one or two packaging bags at the same time, and its sealing operation efficiency is low, which affects the overall rhythm of the entire automatic packaging assembly line. If two parallel linear methods are directly used to achieve the sealing operation of two groups of packaging bags, the space occupied will be greatly increased, and each equipment module will be added, which greatly increases the investment cost.

[0003] Therefore, it is necessary to provide a new automatic sealing and unloading mechanism for packaging bags to solve the above problems. [Summary of the invention]

[0004] The main purpose of the present invention is to provide an automatic sealing and unloading mechanism for packaging bags. Only by adding a sealing device and cleverly utilizing a transfer and grabbing unit, double-in and double-out functions and four groups of sealing devices on both sides can be realized to work simultaneously, thereby greatly improving the efficiency of the sealing and unloading process, shortening the cycle, and reducing costs.

[0005] The present invention achieves the above-mentioned purpose through the following technical scheme: an automatic sealing and unloading mechanism for packaging bags, which includes a first grabbing unit that performs horizontal linear motion, a diversion and transfer unit located below the end of the first grabbing unit and receiving the packaging bags on the first grabbing unit and transferring them to the left and right sides respectively, two sealing units located on both sides of the first grabbing unit, two sealing and transfer units that receive the packaging bags in the diversion and transfer units and move them into the sealing units and simultaneously move the packaging bags out of the sealing units, a converging and transfer unit that receives the packaging bags in the sealing and transfer units on the left and right sides, and a second grabbing unit that receives the packaging bags in the converging and transfer units and places them at the product output end.

[0006] Furthermore, the first grabbing unit and the second grabbing unit both include a first driving member, a first movable plate driven by the first driving member to move forward and backward, and two pairs of first clamping assemblies fixed on the first movable plate; the first clamping assembly includes a first cylinder and a clamping claw driven by the first cylinder to clamp the upper edge of the packaging bag.

[0007] Furthermore, the flow-dividing transfer unit and the flow-merging transfer unit both include a second driving member, a rotating plate driven to rotate by the second driving member, and two groups of second clamping components fixedly distributed at 90 degrees on the rotating plate.

[0029] Please refer to Figure 1-Figure 6 The present invention is an automatic sealing and unloading mechanism 100 for packaging bags, which includes a first grasping unit 1 that performs horizontal linear motion, a diversion and transfer unit 2 located below the end of the first grasping unit 1 and receiving the packaging bags on the first grasping unit 1 and transferring them to the left and right sides respectively, two sealing units 3 located on both sides of the first grasping unit 1, two sealing and transfer units 4 that receive the packaging bags in the diversion and transfer unit 2 and move them into the sealing unit 3 and simultaneously move the packaging bags out of the sealing unit 3, a converging and transfer unit 5 that receives the packaging bags in the sealing and transfer units 4 on the left and right sides, and a second grasping unit 6 that receives the packaging bags in the converging and transfer unit 5 and places them at the product output end.

[0030] The first gripping unit 1 and the second gripping unit 6 have the same structure and both include a first driving member 11, a first movable plate 12 driven by the first driving member 11 to move forward and backward, and two pairs of first clamping assemblies 13 fixed on the first movable plate 12. The first clamping assembly 13 includes a first cylinder 131 and a clamping claw 132 driven by the first cylinder 131 to clamp the upper edge of the packaging bag.

[0031] The flow-dividing and transferring unit 2 has the same structure as the flow-converging and transferring unit 5 and both include a second driving member (not shown in the figure), a rotating plate 21 driven by the second driving member to rotate, two sets of second clamping assemblies 22 fixedly distributed on the rotating plate 21 at 90 degrees, and two pairs of clamping devices are provided in the second clamping assembly 22 and include a second cylinder 221 fixed on the rotating plate 21, a first movable arm 222 and a second movable arm 223 driven by the second cylinder 221 to move relative to each other, a first clamping jaw cylinder 224 fixed on the first movable arm 222, a second clamping jaw cylinder 225 fixed on the second movable arm 223, a clamping jaw 226 driven by the first clamping jaw cylinder 224 to clamp one side of the packaging bag, and a clamping jaw 227 driven by the second clamping jaw cylinder 225 to clamp the other side of the packaging bag. A support plate 23 is provided on the rotating plate 21 below the second clamping assembly 22 to hold the bottom of the packaging bag to prevent it from falling off.

[0032] There are two sealing units 3 arranged in parallel on the same side, and they include a fixed sealing component 31, a movable sealing component 32 arranged opposite to the fixed sealing component 31 and cooperating with the fixed sealing component 31 to achieve sealing of the packaging bag, and a clamping and leveling component 33 located between the fixed sealing component 31 and the movable sealing component 32 for clamping and positioning the sealing edge of the packaging bag.

[0033] The fixed sealing assembly 31 includes a fixed plate 311 , a third cylinder 312 fixed on the fixed plate 311 , and a first sealing heating block 313 driven by the third cylinder 312 to move left and right.

[0034] The movable sealing assembly 32 includes a fourth cylinder 321, a second movable plate 322 driven by the fourth cylinder 321 to move left and right, a fifth cylinder 323 fixed on the second movable plate 322, and a second sealing heating block 324 driven by the fifth cylinder 323 to move left and right and cooperate with the first sealing heating block 313 to achieve sealing. The first sealing heating block 313 and the second sealing heating block 324 are electrically connected to a heating device 34.

[0035] The clamping and leveling assembly 33 includes a sixth cylinder 331 located below the fixed sealing assembly 31, a third movable plate 332 driven by the sixth cylinder 331 to move left and right, a seventh cylinder 333 fixed on the third movable plate 332, and a leveling module 334 driven by the seventh cylinder 333 to move relative to each other. The two leveling modules 334 are located on both sides of the packaging bag.

The leveling module 334 includes a support frame 3341 driven by the seventh cylinder 333 to slide, a leveling clamping strip 3342 located above the support frame 3341, and an elastic stabilizing cloth 3343 stretched on the support frame 3341 and used to stabilize the product inside the packaging bag to prevent shaking. When the two leveling modules 334 move relatively to each other and come closer, the leveling clamping strips 3342 clamp the sealing edge of the packaging bag, and at the same time the elastic stabilizing cloth 3343 covers the bottom of the packaging bag to prevent the packaging bag from shaking.

[0036] The sealing transfer unit 4 includes a third driving member 41, a fourth movable plate 42 driven by the third driving member 41 to move forward and backward, a fourth driving member 43 fixed on the fourth movable plate 42, a fifth movable plate 44 driven by the fourth driving member 43 to move up and down, and two pairs of third clamping components 45 fixed on the fifth movable plate 44.

The shielding piece 453 is mainly used to block the sealing heating block to prevent the packaging bag from being damaged by hitting the sealing heating block during the removal process.

[0038] The working principle of the automatic sealing and unloading mechanism 100 for packaging bags in this embodiment is as follows: the packaging bag containing the product is taken from a packaging bag opening and feeding structure by the first grabbing unit 1, and then moved to the material taking position of the diverting and transferring unit 2; it is clamped by a second clamping component 22 in the diverting and transferring unit 2 and then rotated 90° to the material taking position of the sealing and transferring unit 4; then it is moved to the sealing unit 3 through the sealing and transferring unit 4 to be clamped, and then sealed. After the sealing is completed, it is taken out by the sealing and transferring unit 4 and moved to the material taking position of the converging and transferring unit 5, and then rotated 90° to the second The grabbing unit 6 takes the material, and then it is taken away by the second grabbing unit 6 and put into the product output end; when the diversion and transfer unit 2 realizes a rotation process, one group of the second clamping components 22 completes the clamping of the packaging bag, and the other group of the second clamping components 22 completes the release of the packaging bag. The diversion and transfer unit 2 realizes the diversion and transportation of the two sides of the packaging bag, and the converging and transfer unit 5 realizes the clamping and convergence of the sealed packaging bags on both sides to the second grabbing unit 6, thereby realizing a double-in and double-out, efficient sealing and unloading mode with four packaging bags sealed on both sides at the same time, which greatly improves production efficiency.
