Description

Technical Field

[0001] The invention relates to a novel packaging process and packaging equipment for a protective base in the household appliance industry, belonging to the technical field of household appliance packaging. Background Art

[0002] There are usually two ways to protect traditional home appliance packaging. One is a foam base with PP hollow board for protection; the other is a foam base with ordinary adhesive protective film for protection.

[0003] Both of the above packaging protection methods have defects:

[0004] The method of adding a foam base to a PP hollow board requires skilled workers to pre-form the PP hollow board, and then manually assemble it on the foam. It requires the use of a large amount of glue and tape, which is costly, inefficient, and of unreliable quality. A large amount of glue will pollute the working environment and affect the health of workers. The exposed tape also poses a safety hazard to the smooth operation of the entire production line. In addition, the material of the PP hollow board itself is unstable and easily damaged by moisture.

[0005] The method of adding a foam base with an adhesive protective film will cause a lot of dust, mosquitoes and other debris to stick to the adhesive protective film during the assembly process and product transportation due to the stickiness of the film; in addition, there is a defect that the packing tape at the four corners of the foam base can easily break the foam.

[0006] The existing packaging protection methods have a low degree of automation.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0008] In response to the deficiencies in the background technology, the present invention provides a novel packaging process and packaging equipment for protective bases in the home appliance industry, which can make the manufactured foam base products have good moisture-proof effect; can solve the problem of adherence of impurities during assembly and product transportation; can realize automatic packaging of the protective base; can reduce costs while solving the problem that the four corners of the foam base are easily torn by the packaging tape.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A novel packaging process for protective bases in the home appliance industry specifically comprises the following steps: S1: bonding the non-adhesive film and the adhesive films on the left and right sides together, and then pulling them to the bottom of the foam base;

[0011] S2: Cutting the combination of the non-adhesive film and the adhesive film and applying it to the bottom of the foam base; the longitudinal dimension of the combination of the non-adhesive film and the adhesive film is not greater than the longitudinal dimension of the bottom surface of the foam base, and the transverse dimension of the combination of the non-adhesive film and the adhesive film is greater than the transverse dimension of the bottom surface of the foam base;

[0012] S3: Fold the adhesive film that extends beyond the bottom surface of the foam base to the side of the foam base, and firmly adhere it to the side of the foam base;

[0013] S4: Apply a U-shaped adhesive film to both sides of the foam base, with the ends of the U-shaped adhesive film overlapping with the ends of the adhesive film in step S2;

[0014] S5: Fold the bottom of the U-shaped adhesive film to the bottom of the foam base, and the adhesive film adheres the foam base and the non-adhesive film to complete the wrapping of the non-adhesive film. The folded U-shaped adhesive film will form overlapping parts at the four corners of the bottom of the foam base.

[0015] Furthermore, in the step S4, the overlap size between the end portion of the U-shaped portion with the adhesive film and the end portion of the U-shaped portion with the adhesive film in the step S2 is 10 mm.

[0016] Furthermore, the bonding dimensions of the adhesive film in step S2 and the U-shaped adhesive film in step S4 on the side of the foam base are both 2 mm to 100 mm.

[0017] Furthermore, the size of the overlapping portion between the adhesive film and the non-adhesive film is 2 mm to 75 mm; and both the adhesive film and the non-adhesive film are in the form of rolls.

[0018] A new type of packaging equipment for protective bases in the home appliance industry includes an equipment bracket, on which a vertically arranged roller conveyor line and a belt conveyor line are installed. A loading combination component is provided below the initial conveying end of the roller conveyor line, a slitting and covering component is provided below the middle conveying section of the roller conveyor line, and a side clamping component is provided behind the conveying direction of the slitting and covering component; a side pushing component is provided below the conveying end of the roller conveyor line; side covering components are installed on both sides of the initial conveying end of the belt conveyor line, and a corner sweeping component and a bottom surface clamping component are provided in sequence behind the conveying direction of the side covering component.

[0019] Furthermore, the feeding assembly includes an inflation roller for placing the non-adhesive film coil, a rubber roller is provided on one side of the inflation roller, and the rubber roller synchronously completes the release of the two adhesive films, and a guide roller is provided above the inflation roller.

[0020] Furthermore, the slitting and laminating assembly includes two pressing rollers; the two ends of the pressing rollers are respectively installed on connecting plates, the connecting plates are connected to the cylinder, and the cylinder is fixed on the equipment bracket; a first cutter is provided on one side of the two pressing rollers, the first cutter is installed on the cutter base, and the cutter base is connected to the cylinder.

[0024] After adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0025] The present invention mainly divides the protective film outside the foam base into two parts: a film with adhesive and a non-adhesive film. The adhesive film is distributed around the foam base and directly contacts the foam, while the non-adhesive film is centered and exposed in the hollow of the foam base. This ensures that the protective film is reliably bonded to the foam base and that there is no glue on the exposed protective film in the hollow of the foam base, thereby preventing mosquitoes, dust and other impurities from sticking to it. The product made by the present invention is stable in material, can avoid corrosion, and is not easily damaged by moisture.

[0026] The thickness and number of layers of the adhesive film in the present invention can be selected according to the degree of tightening of the strapping tape and the density of the foam, which can reduce costs while solving the problem that the four corners of the foam base are easily broken by the strapping tape;

[0051] like Figures 1-6 As shown together, the present invention provides a new type of packaging equipment for protective bases in the home appliance industry, including an equipment bracket 1, on which are installed a vertically arranged roller conveyor line 2 and a belt conveyor line 3, and the conveying initial end of the belt conveyor line 3 is located on one side of the conveying end of the roller conveyor line 2; above the roller conveyor line 2 and the belt conveyor line 3 are respectively installed conveying components 4, and the conveying component 4 cooperates with the roller conveyor line 2 up and down, and the conveying component 4 cooperates with the belt conveyor line 3 up and down to realize clamping and conveying of the foam base.

[0052] The conveying component 4 is respectively equipped with a width adjustment component 5 and a height adjustment component 6. The width adjustment component 5 is used to adjust the conveying width of the conveying component 4 to adapt to the changes in the width of different foam bases. The height adjustment component 6 is used to adjust the conveying height of the conveying component 4 to adapt to the changes in the height of different foam bases.

[0053] A loading assembly 7 is provided below the initial conveying end of the roller conveyor line 2, a slitting and covering assembly 8 is provided below the middle conveying section of the roller conveyor line 2, and two groups of symmetrically arranged side clamping assemblies 9 are provided behind the conveying direction of the slitting and covering assembly 8; a side pushing assembly 10 is provided below the conveying end of the roller conveyor line 2.

[0054] The feeding assembly 7 includes an inflation roller 71 for placing the non-adhesive film coil, and a rubber roller 72 is provided on one side of the inflation roller 71. The rubber roller 72 synchronously completes the release of the two adhesive films, and a guide roller 73 is provided above the inflation roller 71; the non-adhesive film on the inflation roller 71 and the adhesive film on the rubber roller 72 are transported to the slitting and laminating assembly 8 through the guide roller 73, and the non-adhesive film and the adhesive film are overlapped and bonded at their edges on the guide roller 73, and the bonded assembly is transported together to the slitting and laminating assembly 8.

[0055] The slitting and laminating assembly 8 includes two pressing rollers 81, which are used to carry the combination of non-adhesive film and adhesive film to realize the transportation of the combination of non-adhesive film and adhesive film; the two ends of the pressing roller 81 are respectively installed on the connecting plate 82, the connecting plate 82 is connected to the cylinder, the cylinder is fixed on the equipment bracket 1, and the cylinder is extended and retracted to realize the lifting and lowering of the two pressing rollers 81; one side of the two pressing rollers 81 is provided with a first cutter 83, the first cutter 83 is installed on the cutter base, and the cutter base is connected to the cylinder; when the belt conveyor line 3 is on the When the photoelectric sensor detects that the foam base passes over the combination of the film without adhesive and the film with adhesive, the cylinder lifts the two pressure rollers 81, so that the adhesive surface of the combination of the film without adhesive and the film with adhesive contacts the bottom of the foam base, and the film is attached to the foam base through the traction of the foam base. When the end of the foam base passes the photoelectric sensor, the cylinder moves downward to leave a gap. At this time, the cylinder of the first cutter 83 is started, and the first cutter 83 moves obliquely upward to complete the cutting of the combination of the film without adhesive and the film with adhesive. This reciprocating motion completes each attaching action.

[0056] The side pressing assembly 9 includes six pressing brushes 91 evenly distributed around the circumference, and the pressing brushes 91 are fixed on a circular brush base 92; the bottom center of the brush base 92 is fixedly connected to the output shaft of the motor, and the motor is installed on the equipment bracket 1. The output shaft of the motor is horizontally arranged, and the motor drives the pressing brush 91 to rotate; when the foam base covered with the combination of the film and the film passes through the position of the side pressing assembly 9, the pressing brush 91 folds the film from bottom to top and covers it on the side of the foam base and brushes it firmly.

[0057] The side push assembly 10 is used to push the coated foam base from the conveying end of the roller conveyor line 2 to the conveying starting end of the belt conveyor line 3; the side push assembly 10 includes a side push plate, which is fixed to the base by screws, and the base is connected to the side push cylinder, which is fixed to the equipment bracket 1 by screws; when the foam base is photoelectrically sensed, the side push cylinder starts to drive the side push plate to push the foam base onto the belt conveyor line 3.

[0058] Side covering components 11 are installed on both sides of the initial conveying end of the belt conveyor line 3, and the two groups of side covering components 11 are symmetrically arranged. The corner sweeping components 12 and the bottom surface pressing components 13 are sequentially arranged behind the side covering components 11 in the conveying direction. There are two groups of corner sweeping components 12 and bottom surface pressing components 13, and the two groups are symmetrically arranged.

[0059] The side covering component 11 includes two covering pressure wheels 111, the center lines of the covering pressure wheels 111 are set vertically, and a second cutter 113 is set between the two covering pressure wheels 111. The covering pressure wheels 111 and the second cutter 113 are both installed in the covering base 112; the two ends of the covering pressure wheel 111 are installed on the angle iron, and the angle iron is connected to the covering base 112 through a tension spring; the second cutter 113 is connected to the covering base 112 through a tension spring; a tension shaft 114 is installed on the outside of the covering base 112, and the tension shaft 114 is used to place the film coil; when the foam base is in contact with the first covering When the pressing wheels 111 make contact, the adhesive film on the first pressing wheel 111 sticks to the side of the foam base, and the foam base continues to move. The adhesive film is continuously pulled onto the foam base and pressed by the pressing wheel 111. At this time, the second cutter 113 also slides on the surface of the foam base. When the first pressing wheel 111 presses over the end of the foam base, the second cutter 113 will quickly reset under the traction of the tension spring, and cut off the adhesive film while resetting. Then the first pressing wheel 111 resets, and the second pressing wheel 111 will continue to slide, squeezing the adhesive film to stick to the side of the foam base until the foam base leaves this area.

[0060] The corner sweeping assembly 12 includes a corner sweeping brush 121, which is fixed to a rotating cylinder 122 via a U-shaped aluminum part, and the rotating cylinder 122 is fixed to the equipment bracket 1 via bolts; when the photoelectric sensing detects the foam base, the rotating cylinder 122 is activated, causing the corner sweeping brush 121 to turn, and the corner sweeping brush 121 contacts the adhesive film at 90 degrees, and folds the adhesive film vertically downward to the bottom of the foam base and sticks it firmly.

[0061] The bottom pressing component 13 has the same specific structure as the side pressing component 9. The difference is that the side pressing component 9 folds the adhesive film and sticks it to the side of the foam base, while the bottom pressing component 13 folds the adhesive film from top to bottom and sticks it to the bottom of the foam base and brushes it firmly.
