Description

Technical Field

[0001] The invention relates to the technical field of edge sealing of packaging bags, and in particular to automatic edge sealing and pressing equipment for aluminum-plastic composite packaging bags. Background Art

[0002] Aluminum-plastic composite bag packaging is a packaging product with low cost and exquisite printing. Aluminum-plastic composite bags are widely used in food packaging, medicinal packaging, electronic product packaging bags, UV protection daily chemical product packaging, etc. The common aluminum-plastic bag products in life are as follows: self-supporting food packaging bags, vacuum food packaging bags, self-supporting nozzle beverage bags, high temperature resistant cooking food bags, aluminum foil tea and coffee bags, anti-static shielding electronic product bags, UV protection daily chemical product bags, etc. According to the bag type, they can be divided into: three-side sealed packaging bags, self-supporting bags, self-supporting nozzle bags, special-shaped self-supporting bags, bags in boxes, special packaging bags, etc.

[0003] The following problems exist in the edge sealing and pressing process of three-side sealed aluminum-plastic composite packaging bags: 1. The packaging bags to be sealed may fall over during transportation on the conveyor belt, so the guide wheels on both sides are generally used to keep the packaging bags standing while being transported, but this will cause damage to fragile and easily deformed items in the conveyor bag; 2. The problem with the three-side sealed plastic composite packaging bags is that the guidance of tearing the seal is poor, and it takes two or even multiple tears to reach the opening size that is convenient for taking out the items in the packaging bag. In order to facilitate tearing the seal, it is necessary to process an easy-tear line at the seal. However, if the two layers of the packaging bag are not kept completely in contact during the cutting of the easy-tear line, the processed easy-tear line will be uneven, thus affecting the use effect.

The distance from the bottom side of the movable inclined slot 22 to the upper end of the loading seat 21 increases from left to right. Two rectangular receiving slots 23 are symmetrically opened on the front and rear side walls of the movable inclined slot 22. Rotating columns 24 are rotatably arranged at both left and right ends of the rectangular receiving slot 23. The outer side walls of the two rotating columns 24 are jointly sleeved with transmission belts 25 through bearings. A plurality of support plates 26 are arranged on the outer side wall of the transmission belt 25 at equal intervals along its movement direction. An L-shaped plate 27 is arranged on the right side wall of the loading seat 21 below the movable inclined slot 22.

[0033] During specific operation, the packaging bags to be sealed are first placed vertically in the moving chute 22 in sequence, and the two sides of the packaging bags to be sealed are fitted with two adjacent support plates 26 on the transmission belt 25. Then, in the moving chute 22, under the action of the packaging bag's own gravity, the packaging bag moves along the moving chute 22, thereby driving the transmission belt 25 to rotate. Under the support of the two adjacent support plates 26 on the transmission belt 25, the packaging bag always remains vertical, and the same is true for the next packaging bag, until the first packaging bag fits with the L-shaped plate 27. When the packaging bag fitted with the L-shaped plate 27 is driven away by the clamping assembly 34, the next packaging bag will continue to move along the moving chute 22 until it fits with the L-shaped plate 27.

[0034] See also Figure 1 and Figure 2 The edge pressing unit 3 includes a supporting cylinder 31, a supporting disc 32, a rotating disc 33, a clamping assembly 34, a pressing assembly 35, an easy-tear line processing assembly 36 and a blanking assembly 37.

[0035] During the specific operation, the first intermittent motor is first started, and the first intermittent motor drives the supporting disc 32 to rotate, and each rotation degree is 90 degrees, and then the clamping assembly 34 located at the automatic feeding unit 2 clamps the packaging bag, and then driven by the supporting disc 32, the clamping assembly 34 holding the packaging bag is driven to the pressing assembly 35, and the pressing assembly 35 performs hot pressure sealing on the packaging bag. At the same time, the adjacent clamping assembly 34 is also brought to the automatic feeding unit 2 and clamps the packaging bag, and then the supporting disc 32 drives the clamping assembly 34 holding the sealed packaging bag to arrive at the easy tear line processing assembly At part 36, the tear line processing component 36 processes the tear line between the sealing part and the sealing mouth. At the same time, the adjacent clamping component 34 is also brought to the pressing component 35 to seal the packaging bag. At this time, the clamping component 34 adjacent to the clamping component 34 holding the sealed packaging bag is driven to the automatic feeding unit 2 and clamps the packaging bag. Then the support disc 32 drives the clamping component 34 holding the packaging bag with the processed tear line to the unloading component 37. At this time, the clamping of the packaging bag is released, and the packaging bag falls onto the unloading component 37 for centralized collection. This cycle is repeated.

The lower end of the cylindrical sliding block 355 is located at the square receiving groove 353 and is symmetrically connected to a connecting rod 356 through a hinge. Two moving groove blocks 357 are symmetrically slidably arranged in the moving groove 354, and the lower end of the connecting rod 356 is hingedly connected to the moving groove block 357 on the same side thereof. A pressing block 358 is arranged at the lower end of the moving groove block 357, and a detachable heating strip 359 is installed on the pressing block 358.

[0039] During specific operation, by starting the second electric push rod, the second electric push rod drives the cylindrical sliding block 355 to move upward, thereby driving the movable slot blocks 357 on both sides to approach each other through the connecting rod 356, until the pressing blocks 358 on both sides are close to each other, thereby heat-pressing and sealing the packaging bag through the heating strip 359, and the cylindrical sliding block 355 is driven downward by the second electric push rod, so that the connecting rods 356 on both sides respectively drive the connected movable slot blocks 357 to move to the side away from the center of the cylindrical sliding block 355, and at this time the two pressing blocks 358 are separated.

[0040] See also Figure 8 and Fig. 9 The tear line processing component 36 includes a second support plate 361, a rectangular accommodating block 362, a rectangular accommodating cavity 363, a pushing block 364, a sliding block 365, a clamping plate 366, a triangular sawtooth 367, a triangular groove 368 and a pressing strip 369.

[0041] During specific operation, the third electric push rod drives the pushing block 364 to move upward. Due to the sliding cooperation between the two sides of the pushing block 364 and the sliding block 365, the pushing block 364 drives the connected clamping plate 366 to move toward the center of the pushing block 364. First, the pressing strips 369 on the left and right sides begin to contact the packaging bag. Through the push of the clamping plate 366, the pressing strips 369 on the left and right sides gradually press the packaging bag. At this time, the two layers of packaging skin at the processing position of the packaging bag remain close, and the clamping plate 366 continues to push, and the pressing strip 369 begins to move toward the inside of the square slide groove until multiple triangular saw teeth 367 pass through the packaging bag and are inserted into the triangular groove 368, pressing a tear line on the packaging bag, and then the pushing block 364 is driven downward by the third electric push rod, thereby driving the clamping plate 366 connected to the pushing block 364 to move to the side away from the center of the pushing block 364. At this time, the triangular saw teeth 367 are separated from the packaging bag, and the pressing strip 369 is reset under the elastic force of the spring.

[0042] See also Fig.10 and Fig.11 The unloading assembly 37 includes an inclined block 371, a baffle 372, a rectangular groove 373 and a conveying roller 374, wherein: an inclined block 371 is arranged at a position below the clamping assembly 34 on the rear side of the support disc 32, baffles 372 are arranged on both sides of the inclined block 371 along its inclination direction, rectangular grooves 373 are opened at corresponding positions on opposite sides of the two baffles 372, and a conveying roller 374 is arranged between the two rectangular grooves 373, and both ends of the conveying roller 374 slide up and down in the rectangular groove 373, and the lower end of the conveying roller 374 located in the rectangular groove 373 cooperates with the rectangular groove 373 through a spring; during specific operation, the packaging bag falls onto the conveying roller 374, and under the elastic force of the spring on the conveying roller 374, it can play a buffering role for the packaging bag that falls onto the conveying roller 374, thereby preventing the items in the packaging bag from falling onto the conveying roller 374 and being damaged. The packaging bag falls onto the conveying roller 374, and the action of the obliquely arranged conveying roller 374 and the driving force of the subsequent rolling of the packaging bag promote the packaging bag to move to the designated position.

[0043] The working process of the present invention is as follows: Step 1: During the specific operation, the packaging bags to be sealed are first placed vertically in the moving chute 22 in turn, and the two sides of the packaging bags to be sealed are in contact with the two adjacent support plates 26 on the transmission belt 25. Then, in the moving chute 22, under the action of the packaging bag's own gravity, the packaging bag moves along the moving chute 22, thereby driving the transmission belt 25 to rotate. Under the support of the two adjacent support plates 26 on the transmission belt 25, the packaging bag always remains vertical, and the same is true for the next packaging bag, until the first packaging bag is in contact with the L-shaped plate 27. When the packaging bag in contact with the L-shaped plate 27 is driven away by the clamping assembly 34, the next packaging bag will continue to move along the moving chute 22 until it is in contact with the L-shaped plate 27.

[0044] Step 2: Start the first intermittent motor, which drives the support disc 32 to rotate 90 degrees each time, and then the clamping assembly 34 located at the automatic feeding unit 2 clamps the packaging bag, and then driven by the support disc 32, the clamping assembly 34 holding the packaging bag is driven to the pressing assembly 35, and the pressing assembly 35 performs hot-pressing sealing on the packaging bag. At the same time, the adjacent clamping assembly 34 is also brought to the automatic feeding unit 2 and clamps the packaging bag, and then the support disc 32 drives the clamping assembly 34 holding the sealed packaging bag to the easy-tear line. At the working component 36, the easy-tear line processing component 36 processes the easy-tear line between the sealing part and the sealing mouth. At the same time, the adjacent clamping component 34 is also brought to the pressing component 35 to seal the packaging bag. At this time, the clamping component 34 adjacent to the clamping component 34 holding the sealed packaging bag is driven to the automatic feeding unit 2 and clamps the packaging bag. Then the supporting disc 32 drives the clamping component 34 holding the packaging bag with the processed easy-tear line to the unloading component 37. At this time, the clamping of the packaging bag is released, and the packaging bag falls onto the unloading component 37 for centralized collection.

[0045] Step 3: Repeat this cycle.
