Description

Technical Field

[0001] The present invention relates to the technical field of food packaging, and more specifically, to a food packaging laminated paper processing device and method. Background Art

[0002] Laminated paper is also called PE laminated paper, pe laminated paper, single plastic laminated paper, double plastic laminated paper, waterproof laminated paper, moisture-proof laminated paper, PE paper, plastic-coated paper, and oil-proof paper. It is a composite material in which plastic particles are coated on the surface of paper through a cast film machine.

[0003] Food packaging laminated paper has a layer of plastic film coated on the surface, which can effectively prevent moisture penetration and keep the inside of the food dry, thereby extending the shelf life of the food. At the same time, for oily foods, the film layer on the surface can block the penetration of grease, preventing the food from deteriorating or affecting the appearance due to grease seepage. Relying on this film layer, it can isolate the outside air, moisture and impurities to a certain extent, thereby slowing down the chemical reactions and microbial reproduction inside the food, effectively extending the shelf life of the food.

[0004] At present, in the process of processing laminated paper for food packaging, in order to facilitate the direct use of laminated paper to package food, etc., processing equipment is used to cut the laminated paper. However, when the existing processing equipment cuts the laminated paper, due to the thinness and lightness of the laminated paper, the laminated paper may float up during cutting, resulting in uneven wrinkles of the laminated paper during cutting, resulting in deviations in the size of the laminated paper after cutting, which may affect its normal use later.

[0015] As a further solution of the present invention: a method for using a food packaging laminated paper processing device, specifically comprising the following steps:

[0016] Step 1: When cutting the food packaging coated paper, clamp the new coated paper roll on the two mounting rollers in the winding direction and fix it with bolts, then pass one end of the coated paper through the three sets of limiting rollers, the driving roller and the cutting plate, and limit one end of the coated paper under the lower driving roller;

[0018] Step 3: After the laminated paper is cut, the processing mechanism continues to move toward the middle along the threaded rod. At this time, the cutting mechanism stops pressing the laminated paper. The laminated paper moves toward the cutting plate under the action of the driving roller, and external air enters through the holes on the elastic airbag. After the pressure inside and outside the elastic airbag is the same, the cut laminated paper can slide down, making room for the uncut laminated paper to continue processing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By arranging a blowing and suction mechanism, a processing mechanism and a fixed plate on one side of the driving equipment box, when the driving motor drives the laminated paper on the laminated paper roll to move to the side of the cutting plate, the processing mechanism is also driven by the belt to move along the limit groove on the fixed plate, and the elastic airbag in the blowing and suction mechanism can also be pressed. The laminated paper is flattened to both sides by two bent scrapers. Then the elastic airbag is under negative pressure, which can tightly adsorb the laminated paper on the cutting plate, ensuring that the cutting mechanism cuts the laminated paper with a smooth incision, and the size of the laminated paper cut off is more in line with the requirements.

[0021] 2. When the driving motor drives the installation roller to rotate, the belt can drive the threaded rod and the two driving rollers to rotate, and the processing mechanism rotates along the threaded rod to flatten the laminated paper to both sides, while the two driving rollers can contact the laminated paper. Relying on the friction between the laminated paper bottom paper layer, the laminated paper can be transmitted downward by a fixed length, thereby cutting the laminated paper at a fixed length. When the two bent scrapers move to both sides to flatten the laminated paper, the hair on the bottom paper layer of the inferior laminated paper can be cleaned with the cooperation of the hair absorbers on both sides.

[0022] 3. By setting a folding frame, a pressure roller and a spring in the cutting mechanism, when the electric telescopic rod drives the folding frame to move, the force of the pressure roller on the cutting plate can be controlled. When the pressure between the pressure roller and the coated paper is greater than the friction between the coated paper and the lower driving roller, the coated paper cannot continue to be transmitted downward, which is convenient for the cutting mechanism to cut the coated paper into a fixed length. When the pressure between the pressure roller and the coated paper is less than the friction between the coated paper and the lower driving roller, the lower driving roller can transmit the coated paper downward normally, which is convenient for subsequent cutting.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 8 The present invention further describes an embodiment of a food packaging laminated paper processing device and method.

[0035] A food packaging coated paper processing device, comprising a driving device box 1, a blowing and sucking mechanism 2 is fixedly installed on one side of the driving device box 1, a processing mechanism 3 is installed inside the driving device box 1, the tops of both ends of the processing mechanism 3 extend to the front and rear sides of the blowing and sucking mechanism 2 respectively and contact the blowing and sucking mechanism 2, and a cutting mechanism 4 is fixedly installed inside the driving device box 1;

[0036] The blowing and suction mechanism 2 includes a cutting plate 21, both ends of which are fixedly mounted on both sides of the inner wall of the driving device box 1, a plurality of blowing and suction holes 22 are evenly opened on the surface of the cutting plate 21, a limiting empty box 23 is installed on the back of the cutting plate 21, and elastic air bags 24 are evenly arranged on one side of the inner wall of the limiting empty box 23, and one end of the plurality of elastic air bags 24 penetrates the limiting empty box 23 and is fixed to the cutting plate 2 1, one end of the plurality of elastic air bags 24 corresponds to the position of the blowing and sucking hole 22, a pressing piece 25 is provided inside the limiting empty box 23 and on one side of the elastic air bag 24, one end of the plurality of pressing pieces 25 penetrates the limiting empty box 23 and extends to the outside of the limiting empty box 23, one end of the plurality of pressing pieces 25 is fixedly connected with an arc plate 26, when the processing mechanism 3 moves along the driving device box 1, the top of one end contacts the arc plate 26 and squeezes the elastic air bag 24, and one side of the other end of the processing mechanism 3 contacts the surface of the cutting plate 21.

[0037] Among them, the blowing and sucking mechanism 2, the processing mechanism 3, the cutting mechanism 4 and the coated paper roll to be processed are all installed inside the driving equipment box 1, and the blowing and sucking mechanism 2 cooperates with the processing mechanism 3. When the coated paper is between the two, the processing mechanism 3 can work and cooperate with the blowing and sucking mechanism 2 to flatly adsorb the coated paper on the blowing and sucking mechanism 2, so as to ensure that the position of the coated paper is flat and without wrinkles. At the same time, when the cutting mechanism 4 is cutting the coated paper, the coated paper is also tightly fitted with the cutting plate 21, and there is no gap or the gap is very small between the two, so as to ensure that the size of the coated paper is more accurate after cutting. When the coated paper contacts the cutting mechanism 4, the force is more uniform, so as to ensure that the cut of the coated paper is more uniform and no burrs appear. The cutting plate 21 is welded in the middle of the driving equipment box 1, and the bottom end of the cutting plate 21 is tilted to one end. When the coated paper is cut and slides down, it can be directly cut along the bottom of the inclined cutting plate 21. After sliding out, it can be collected by staff or machines. The number and position of the blowing and sucking holes 22 correspond to the elastic airbag 24 inside the limiting empty box 23. A small hole is opened on the elastic airbag 24 and located inside the limiting empty box 23. When the elastic airbag 24 rebounds, one end of the blowing and sucking hole 22 is stably adsorbed by the coated paper, affecting the normal entry of gas into the elastic airbag 24. Therefore, relying on this small hole, the elastic airbag 24 can slowly rebound, and the end of the blowing and sucking hole 22 is slightly smaller to avoid the blowing and sucking hole 22 being too large, directly sucking the coated paper into the blowing and sucking hole 22, resulting in uneven coating paper. Connecting holes 37 are opened on the front and back sides of the limiting empty box 23, one end of the elastic airbag 24 extends out and adheres to the cutting plate 21, and one end of the pressing piece 25 extends to the outside of the limiting empty box 23 through these connecting holes 37, and a plurality of arc plates 26 are connected to the pressing piece 25.

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the driving device box 1 includes a device box 11 and a connecting plate 12, and the device box 11 and the connecting plate 12 are rotatably connected to the opposite sides thereof with mounting rollers 13, and the coated paper roll is installed between the two mounting rollers 13 by bolts, and a plurality of limiting rollers 17 are rotatably installed between the device box 11 and the connecting plate 12 and above the device box 11, and a driving motor 14 is fixedly installed inside the device box 11 and on one side of the mounting roller 13, and one end of the output shaft of the driving motor 14 is fixedly connected to a gear 15 through a coupling, and one end of one of the mounting rollers 13 is fixedly installed with a gear 2 16, and the gear 15 is meshed with the gear 2 16.

[0039] The device box 11 has a relatively large internal cavity, and the drive motor 14 and the like can be installed inside the device box 11. One side of the device box 11 is fixed by bolts. After disassembly, the internal equipment can be repaired and replaced. The connecting plate 12 is connected to the device box 11 to provide a fixed position for the installation rollers 13 and the limit rollers 17. The two installation rollers 13 are adapted to the laminated paper rolls and are fixed by bolts. After the laminated paper is used up, the remaining laminated paper rollers can also be disassembled. The six limit rollers 17 are divided into three groups, and the limit rollers 17 are arranged in pairs. The coated paper passes through it, and the limiting roller 17 below supports the coated paper, while the limiting roller 17 above the coated paper can contact the bottom paper of the coated paper, clean the surface of the bottom paper layer of the coated paper, and deal with the lint that may exist in the bottom paper layer of the coated paper. Gear 1 15 and gear 2 16 are meshed, wherein gear 1 15 is the driving wheel and gear 2 16 is the driven wheel. When the drive motor 14 is started, it can drive a mounting roller 13 to rotate. The drive motor 14 is a servo motor, which is connected to an external power supply through a power cord.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, the bottom of one side of the connecting plate 12 is rotatably connected to a threaded rod 18, and the top of one side of the connecting plate 12 is rotatably connected to a driving roller 19. One end of the threaded rod 18 and the two driving rollers 19 penetrate the device box 11 and extend to the interior of the device box 11. The ends of the threaded rod 18 and the two driving rollers 19 are connected to the installation roller 13 by means of belts and pulleys.

[0041] Among them, one end of the threaded rod 18 and the two driving rollers 19 are all inserted into the device box 11, and pulleys are installed on the threaded rod 18, the two driving rollers 19 and the installation roller 13. The installation roller 13 and the threaded rod 18 are connected by a belt transmission, and the installation roller 13 is connected to one of the driving rollers 19 by a belt, and the two driving rollers 19 are also connected by a belt transmission. The surfaces of the two driving rollers 19 are covered with rubber sleeves, and the friction between them and the coated paper is relatively large, which can effectively convey the coated paper downward. The threads on the surface of the threaded rod 18 are symmetrically opened, and the threaded rod 18 is a reciprocating screw, which ensures that the processing mechanism 3 can reciprocate along the threaded rod 18.

[0042] like Figure 1 , Figure 3As shown, the processing mechanism 3 includes two bending scrapers 31 and a support plate 32, the bottom of one side of the two bending scrapers 31 is slidably connected with a threaded connector 33, one end of the two threaded connectors 33 is commonly threadedly connected to the threaded rod 18, the inner parts of the two bending scrapers 31 and the opposite sides of the two support plates 32 are commonly slidably connected with a limiting connector 34, the tops of one end of the two support plates 32 are fixedly connected with a pressure rod 35, and the two pressure rods 35 are in contact with the arc plate 26, the two bending scrapers 31 and the opposite sides of the bottom of the support plate 32 are fixedly connected with a slider 36, a connecting hole 37 is opened on the surface of one of the bending scrapers 31, and a pressure plate 38 is fixedly connected to the surface of the other bending scraper 31.

[0043] The two ends of the two limit connectors 34 are located in the grooves of the bending scraper plates 31 and the supporting plate 32. There is a distance difference between the positions of the two pressure rods 35 and the positions between the bending scraper plates 31 to ensure that when the pressure rods 35 press the arc plate 26 and are about to leave, the bending scraper plates 31 can contact the coating paper, thereby pushing the coating paper to both sides and flattening the coating paper. After that, when the elastic airbag 24 rebounds and inhales, the flattened coating paper can be flatly adsorbed on the cutting plate 21 to ensure that the coating paper can be flatly attached to the cutting plate 21. The connecting hole 37 corresponds to the size and position of the pressing plate 38. When the cut coating paper slides down along the cutting plate 21, it is restricted by the pressing plate 38 and can slide down along the cutting plate 21.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, a fixing plate 5 is fixedly installed between the device box 11 and the connecting plate 12 and at the bottom of the processing mechanism 3. Limiting grooves 6 are provided on all sides of the top of the fixing plate 5. The bottom ends of the four sliding blocks 36 extend to the inside of the four limiting grooves 6 respectively. Inclined blocks 7 are provided inside the four limiting grooves 6 at one end away from each other. The bottom end of the sliding block 36 can contact the inclined block 7.

[0045] Among them, the fixed plate 5 is welded between the device box 11 and the connecting plate 12, and four limit grooves 6 are symmetrically opened above the fixed plate 5. The four sliders 36 are respectively located in the four limit grooves 6. When the processing mechanism 3 moves under the drive of the threaded rod 18, it can rotate along the limit groove 6. There are two inclined blocks 7 in each limit groove 6. The two inclined blocks 7 are symmetrically arranged at the turning point of the limit groove 6. A spring 46 is arranged at the contact point between the inclined block 7 and the limit groove 6. After contacting the slider 36, it can retract downward by a certain distance to ensure that the slider 36 can pass over the inclined block 7, and ensure that when the threaded rod 18 drives the processing mechanism 3 to rotate, the slider 36 can continue to move to one end when it moves to the bending point of the limit groove 6 instead of moving back.

[0046] like Figure 1 , Figure 7 As shown, the cutting mechanism 4 includes a bracket 41, both ends of which are fixedly installed with the device box 11 and the connecting plate 12 respectively, an electric telescopic rod 42 is fixedly installed in the middle of one side of the bracket 41, and a paper cutter 43 is fixedly installed at one end of the electric telescopic rod 42. A folding frame 44 is provided on one side of the bracket 41 and at the top of the electric telescopic rod 42, a pressure roller 45 is fixedly installed in the middle of one end of the folding frame 44, and a spring 46 is sleeved on the surface of the folding frame 44 and located on one side of the bracket 41.

[0047] Among them, the two ends of the bracket 41 are welded together with the device box 11 and the connecting plate 12 to provide a support position for the electric telescopic rod 42. The electric telescopic rod 42 is connected to an external power supply through a power cord. The extended length of the electric telescopic rod 42 is controlled to ensure that the processing equipment can stably cut the coated paper. The paper cutter 43 is relatively sharp. The folding frame 44 sends the pressure roller 45 forward for a length longer than the paper cutter 43. When the pressure roller 45 contacts the coated paper on the cutting plate 21, the paper cutter 43 will not contact the coated paper. The spring 46 has good elasticity and can be compressed.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, a hair sucker 8 is fixedly installed on the opposite side of the device box 11 and the connecting plate 12 and on one side of the two bent scrapers 31, and a pressure switch 9 is fixedly installed on the opposite side of the device box 11 and the connecting plate 12 and on one side of the hair sucker 8. The two pressure switches 9 can contact one side of the two bent scrapers 31.

[0049] Among them, the hair absorber 8 can absorb the hair scraped off the surface of the two curved scrapers 31 to ensure that the curved scrapers 31 are clean. After the curved scrapers 31 come into contact with the pressure switch 9, the hair absorber 8 can be controlled to open to clean the hair on the bottom paper layer of the inferior coated paper.

[0050] Directions:

[0051] Step 1: When cutting the food packaging coated paper, first remove the coated paper winding roller from between the two mounting rollers 13, then clamp the new coated paper roll on the two mounting rollers 13 according to the winding direction of the new coated paper roll and fix it with bolts, then tear off the protective layer wrapped around the outside of the coated paper roll, pull the beginning of the coated paper roll, pass it through the three sets of limit rollers 17, and then continue to pull the coated paper. After the end of the coated paper passes between the upper driving roller 19 and the cutting plate 21, the staff can push the pressing roller 45 to one end of the folding frame 44, and the pressing roller 45 can be pressed on the coated paper, and the bottom end of the coated paper contacts the lower driving roller 19, and the pressing roller 45 and the cutting plate 21 cooperate to stably clamp the end of the coated paper;

[0052] Step 2. After the preparation work is completed, the staff can control the processing equipment to start through the control switch on the device box 11, and the drive motor 14 starts the transmission gear 15 to rotate. Since the gear 15 is meshed with the gear 2 16, it can drive one of the installation rollers 13 to rotate, and then drive the coated paper roll and the other installation roller 13 to rotate. At the same time, during the rotation of this installation roller 13, with the cooperation of the belt and the pulley, it can drive the threaded rod 18 and the two driving rollers 19 to rotate together, and the coated paper roll is loosened and transported downward with the cooperation of one of the driving rollers 19. Under the pressure of the pressing roller 45, the coated paper can be stacked between the cutting plate 21 and the two bending scrapers 31. In this process, the two bending scrapers The plate 31 also moves from the middle of the threaded rod 18 to both sides at the same time, and directly rubs against the surface of the cutting plate 21. When the two bent scrapers 31 and the support plate 32 move to the edge of the threaded rod 18, they rely on the slider 36 to move inside the limit groove 6 and away from the cutting plate 21 and the curved plate 26. At this time, the electric telescopic rod 42 quickly shrinks a certain distance, and the pressure applied to the coated paper by the pressure roller 45 is weakened, while the driving roller 19 that has been rotating below can drive the coated paper downward, so that the coated paper can be vertically located on one side of the cutting plate 21. During the process of the driving roller 19 below driving the coated paper downward, the driving roller 19 above also keeps driving the loosened coated paper on the coated paper roll downward, so that the coated paper is still in the folding notch at the two bent scrapers 31. After the scraper 31 and the support plate 32 move toward the middle along the limiting groove 6, the electric telescopic rod 42 extends a certain distance, so that the pressure roller 45 presses the coated paper onto the cutting plate 21 again. At this time, the friction between the pressure roller 45 and the coated paper is greater than the friction applied to the coated paper by the lower driving roller 19, and the coated paper can be stacked on the pressure roller 45 again. At the same time, the two bent scrapers 31 and the support plate 32 also move to the middle and approach the cutting plate 21 and the curved plate 26 along the limiting groove 6. The two pressure rods 35 first contact the curved plate 26, so that the pressure piece 25 moves toward the inside of the limiting empty box 23 to press the elastic airbag 24. At this time, the gas inside the elastic airbag 24 is blown out through the blowing and suction holes 22 to blow up the coated paper. 6, the two bending scrapers 31 also come into contact with the surface of the coated paper and press the coated paper onto the cutting plate 21, and then the two bending scrapers 31 move to both sides to scrape the coated paper to both sides, and the upper elastic airbag 24 relies on its excellent resilience to move the pressing piece 25 and the arc plate 26 on one side to one side, and during the rebound of the elastic airbag 24, it is necessary to inhale, so that the coated paper that is scraped flat by the bending scraper 31 can be relied on the blowing and suction holes 22 on the cutting plate 21. The processing mechanism 3 moves to both sides under the drive of the threaded rod 18, and the bending scraper 31 scrapes the previously blown-up coated paper flat, and then the elastic airbag 24 relies on the blowing and suction holes 22 to stably adsorb the flat coated paper on the cutting plate 21. When the two bending scrapers 31 move out of the range of the coated paper,The elastic airbag 24 can continue to absorb the laminated paper. At this time, the electric telescopic rod 42 is extended again to a certain distance, so that the paper cutter 43 fits the laminated paper and cuts the laminated paper.

[0053] Step 3, after the coated paper is cut, the processing mechanism 3 continues to rotate along the threaded rod 18. After the bending scraper 31 and the pressure rod 35 are separated from the cutting plate 21 and the arc plate 26, the external air gradually enters the elastic airbag 24 from the gap between the coating paper and the blowing and suction holes 22 on the cutting plate 21. The air pressure at the elastic airbag 24 and the elastic strong 24 is consistent with the atmospheric pressure. The cut coated paper can slide down along the cutting plate 21 under the limit of the pressure plate 38, and then it is collected by the staff or the tools used in conjunction. At the same time, the driving roller 19 below continues to convey the coated paper downward and continues to cut the coated paper uniformly.

4. A method for using the food packaging laminated paper processing equipment according to claim 3, characterized in that: The specific steps include: Step 1: When cutting the food packaging coated paper, clamp a new coated paper roll on two mounting rollers (13) in the winding direction of the coated paper roll and fix it with bolts, then pass one end of the coated paper through three sets of limiting rollers (17), a driving roller (19) and a cutting plate (21), and limit one end of the coated paper below the lower driving roller (19); Step 2: Start the driving device box (1), the driving roller (19) transfers the coated paper to the side of the cutting plate (21), and the processing mechanism (3) moves along the threaded rod (18) in the driving device box (1). When the processing mechanism (3) moves to the middle, the two pressing rods (35) first contact the two arc-shaped plates (26) located in the middle, and the elastic airbag (24) is pressed by the pressing piece (25). The gas blows the coated paper to the side of the bending scraper (31). Then, when the processing mechanism (3) continues to move along the threaded rod (18), the two bending scrapers (31 ) presses the middle of the coated paper onto the cutting plate (21), and the two pressing rods (35) move to the next arc plate (26). The upper arc plate (26) no longer squeezes the elastic airbag (24), and it needs to inhale air, so that the coated paper scraped flat by the bent scraper (31) can be tightly adsorbed on the cutting plate (21). The processing mechanism (3) applies force to each elastic airbag (24) in turn, so that it blows and inhales air, and at the same time flattens the coated paper. After the processing mechanism (3) moves to the two ends of the threaded rod (18), the cutting mechanism (4) can cut the coated paper; Step 3: After the laminated paper is cut, the processing mechanism (3) continues to move toward the middle along the threaded rod (18). At this time, the cutting mechanism (4) stops pressing the laminated paper. The laminated paper moves toward the side of the cutting plate (21) under the action of the driving roller (19). External air enters through the holes on the elastic airbag (24). After the pressure inside and outside the elastic airbag (24) is the same, the cut laminated paper can slide down, leaving space for the uncut laminated paper to continue processing.
