Description

Technical Field

[0001] The invention relates to the technical field of aluminum-paper composite printing and dyeing, in particular to an aluminum-paper composite printing and dyeing machine. Background Art

[0002] Aluminum foil paper refers to paper made by pasting aluminum foil backing paper and aluminum foil backing. It is soft and easy to deform, just like paper, and it does not rebound after deformation. It can be qualitative, ensure light blocking, will not fall off, is not light-transmissive, has no pollution, and is cheap. It is used for moisture-proof and decorative packaging of high-end cigarettes, candies and other foods.

[0003] After searching, Chinese patent No. CN101367277A discloses an aluminum-paper composite printing and dyeing machine, which includes: various rollers and dryers, and their positions on the frame are aluminum foil roller, glue roller, paper roller, composite roller, pressure roller, dryer, printing and dyeing roller, pressure roller, dryer and finished product roller in the following order, and each roller is supported on the frame by bearings.

[0004] Although the above-mentioned aluminum-paper composite printing and dyeing machine realizes the composite and printing and dyeing of aluminum foil and paper products, the efficiency is greatly improved, the structure is simple, and its cost is much lower than similar products, it still has the following shortcomings:

[0005] When the aluminum foil passes through the glue coating roller, a layer of glue will adhere to the surface of the aluminum foil. Therefore, when it is pressed with paper, excess glue will overflow from the gap between the aluminum foil and the paper. Since the glue has a certain viscosity, the overflowed glue will hang on the aluminum foil and then be dried when passing through the dryer. The dried glue will hang on the aluminum foil in the form of filaments.

[0006] After drying, the dried glue hangs on the edge of the aluminum foil. Since the dyeing roller is attached with wet dye, the suspended dry glue may stick to the dyeing roller under the action of the dye during the subsequent dyeing process. Although the aluminum foil has good ductility, it is very easy to tear, and the dry glue is at the edge of the aluminum foil, so the probability of damage to the aluminum foil is increased when the aluminum foil passes through the dyeing roller.

[0007] Therefore, an aluminum-paper composite printing and dyeing machine is proposed. Summary of the invention

[0008] The purpose of the present invention is to provide an aluminum-paper composite printing and dyeing machine to solve the problem raised in the above-mentioned background technology that during the lamination process, excess glue overflows from the gap between the aluminum foil and the paper, and becomes filaments hanging on the aluminum foil when drying. If not handled in time, it will be rolled into the aluminum foil during winding. When the aluminum foil is used to package food, it will stick to the wet food and be eaten by people.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A composite aluminum-paper printing and dyeing machine comprises a first bracket, on which a pressing roller and a steering roller are horizontally rotatably mounted, a dryer is fixedly mounted on the first bracket, the dryer is located below the steering roller, a box is fixedly mounted on the first bracket at a position below the dryer, a feed inlet and a discharge outlet are symmetrically provided on the top and bottom walls of the box, a first double-headed motor is fixedly mounted in the box, both output ends of the first double-headed motor are mounted with a cutter head that cooperates with the edge of aluminum foil, and a clamping mechanism for limiting the shaking of the aluminum foil is provided in the box.

[0011] During the working process, the aluminum foil and paper coated with glue are pressed together after passing through the pressing roller to form aluminum foil paper. Under the action of the steering roller, the aluminum foil paper changes from the original horizontal movement to the vertical movement. The glue of the aluminum foil paper moving in the vertical direction will be air-dried when it passes through the dryer. Since the aluminum foil and the paper are tightly attached during the pressing process, the glue on the surface of the aluminum foil will overflow from the gap between the aluminum foil and the paper. Since the glue is sticky, the overflowed glue will still stick to the glue in the interlayer between the aluminum foil and the paper, that is, the overflowed glue will hang on the gap between the aluminum foil and the paper. At the bonding point, when passing through the dryer, the overflowed glue will also be dried to form dry glue. When the aluminum foil passes through the feed port and enters the box, the first double-headed motor drives the cutter head to rotate rapidly. Since the cutter head cooperates with the edge of the aluminum foil, when the cutter head rotates rapidly, it will hit the dry glue hanging at the connection between the aluminum foil and the paper. Since the thickness of the cutter head is relatively thin, the contact area of ​​the cutter head when it contacts the dry glue is relatively small, so the pressure at the contact point is relatively large, so that the hanging dry glue can be cut off, which prevents the dry glue hanging on the edge of the aluminum foil from being rolled in when winding.

[0012] Preferably, the clamping mechanism includes a first mounting plate vertically fixedly mounted on the side walls of the feed port and the discharge port, two second mounting plates cooperating with the first mounting plate are installed in the box body, sponges are fixedly mounted on the side walls on opposite sides of the first mounting plate and the second mounting plate, and an adjustment mechanism cooperating with the second mounting plate is provided in the box body.

[0013] Since the first double-headed motor drives the cutter head to cut the dry glue on the edge of the aluminum foil, it relies on the impact force of the cutter head edge on the dry glue to cut it off, and the dry glue and the aluminum foil are connected together. Therefore, at the moment the cutter head hits the edge of the dry glue, the aluminum foil will shake slightly. When the aluminum foil shakes slightly, since the sponge is in close contact with it, the kinetic energy of the aluminum foil when shaking will be transferred to the sponge. Since the sponge is elastic, it will still fit tightly with the aluminum foil after absorbing the kinetic energy of the aluminum foil. Therefore, it can prevent the aluminum foil from shaking over a large range and prevent the aluminum foil from being damaged by the cutter head due to shaking. In addition, the sponge is relatively fluffy. Therefore, after absorbing the kinetic energy of the aluminum foil, the fibers of the sponge itself will shake, and the elastic potential energy will be converted into internal energy during the shaking process, thereby continuously absorbing the kinetic energy of the aluminum foil.

[0014] Preferably, the adjustment mechanism includes two groups of slide grooves symmetrically opened on the inner top wall and the inner bottom wall of the box body, the two second mounting plates are movably installed in one group of slide grooves respectively, the two output ends of the first double-headed motor are fixedly installed with guide rods, the guide rods are symmetrically provided with guide grooves cooperating with the cutter head, the two guide rods are fixedly installed with blocking blocks at one end away from each other, the cutter head is movably sleeved on the guide groove, the guide rods are sleeved with a first spring, the two ends of the first spring are respectively fixedly connected to the cutter head and the blocking block, and the box body is provided with a driving mechanism cooperating with the second mounting plate and the cutter head.

[0015] In the initial state, under the action of the first spring, the two second mounting plates are pushed to the end of the slide groove where they are close to each other, and under the action of the second spring, the cutter head is guided to the end of the first double-headed motor on the guide groove. Therefore, when producing aluminum foil of larger size, the two second mounting plates slide in the slide groove and move away from each other under the action of the driving mechanism, thereby changing the distance between the two second mounting plates, so that aluminum foil of different sizes can be clamped. At the same time, the two cutter heads are moved to the ends of the two guide grooves where they are away from each other through the driving mechanism, thereby changing the spacing between the two cutter heads, so that the cutter heads can always fit the edge of the aluminum foil, thereby expanding the scope of use.

[0016] Preferably, the driving mechanism comprises a first cylinder fixedly mounted in the casing, two first piston plates and a second piston plate movably provided in the first cylinder, first push rods fixedly connected to the two second mounting plates are horizontally fixedly mounted on the side walls of the two first piston plates, a second push rod extending outside the casing is horizontally fixedly mounted on the second piston plate, a second cylinder is fixedly mounted on the first double-headed motor, two third piston plates and a fourth piston plate movably provided in the second cylinder, third push rods in contact with the cutter head are horizontally fixedly mounted on the side walls of the two third piston plates, a groove is provided at one end of the third push rod in contact with the cutter head, a steel ball is movably embedded in the groove, a fourth push rod extending outside the casing is horizontally fixedly mounted on the fourth piston plate, a threaded rod is horizontally fixedly mounted on the outer wall of the casing, a nut is threadedly mounted on the threaded rod, a fixed plate is movably sleeved on a portion of the threaded rod between the nut and the casing, an end of the second push rod and the fourth push rod extending outside the casing is respectively fixedly mounted on two ends of the fixed plate, and a second spring is sleeved on a portion of the threaded rod between the casing and the fixed plate.

[0017] In the initial state, the nut is at the end of the threaded rod away from the box body, and under the action of the second spring, the fixing plate is tightly fitted with the side wall of the nut, so the first cylinder and the second cylinder are both in a negative pressure state, so the first piston plate drives the first push rod to retract, and the first push rod drives the two mounting plates to move to one end where the two slide grooves are close to each other, and when the third piston plate drives the third push rod to retract into the second cylinder, the cutter head can slide freely along the guide groove, so under the action of the first spring, the two cutter heads move to one end where the two guide grooves are close to each other.

[0018] When the distance between the two second mounting plates and the two cutter heads needs to be changed, the nut is screwed to move the nut on the threaded rod and drive the fixing plate to move toward the direction close to the box body, and the fixing plate is used to drive the second push rod and the fourth push rod to move. When the second push rod and the fourth push rod move, the second piston plate and the fourth piston plate move along the inner walls of the first cylinder and the second cylinder respectively, thereby increasing the pressure in the first cylinder and the second cylinder respectively. Therefore, the first piston plate and the third piston plate move along the inner walls of the first cylinder and the second cylinder respectively to balance the pressure. When the first piston plate and the second piston plate move, they respectively drive the first The push rod and the second push rod move, so when the first push rod extends from the first cylinder, it pushes the second mounting plate to move along the slide groove, so that the two second mounting plates move away from each other, which plays a role of changing the distance between the two second mounting plates. When the third push rod moves, it can push the two cutter heads to move along the guide groove and move to one end of the two guide grooves moving away from each other, which plays a role of changing the distance between the two cutter heads, thereby expanding the scope of use. Under the action of the steel ball, the sliding friction between the third push rod and the cutter head is converted into rolling friction between the steel ball and the cutter head, reducing the friction force, thereby making the rotation of the cutter head smoother.

[0019] Preferably, a collecting box is fixedly mounted on the bottom wall of the box body, the collecting box is filled with clean water, a conduit is fixedly mounted on the bottom wall of the box body, the conduit extends into the collecting box, the water surface in the collecting box is located above the conduit, a second double-headed motor is fixedly mounted on the top wall of the box body, an air pump is fixedly mounted on the first output end of the second double-headed motor, an air intake pipe is fixedly mounted on the air inlet of the air pump, and the air intake pipe extends into the collecting box.

[0020] During the working process, the second double-headed motor is started, and the air pump is driven by the second double-headed motor. Since the air intake pipe installed on the air inlet of the air pump extends into the collection box, and the collection box is filled with clean water, the air in the space above the water surface in the collection box will be pumped out during the working process of the air pump. When the air is pumped out, the pressure in the space decreases, so the air is absorbed from the box through the conduit to balance the pressure, so the gas in the box will enter the collection box, and the cut dry glue is suspended in the air in the box, so when the air in the box enters the collection box, the dry glue suspended in the air will also enter it with the air, thereby achieving the effect of collecting the dry glue suspended in the box.

[0021] Preferably, a fixing rod is vertically fixed on the inner bottom wall of the collection box, and the top end of the fixing rod is hinged with two hinged plates that fit tightly with the side walls of the collection box. A first magnet is fixedly installed on the fixing rod at a position below the hinged plate, and a second magnet that repel each other with the first magnet is fixedly installed on the bottom walls of the two hinged plates. An alarm mechanism is provided in the collection box.

[0022] In the initial state, the first magnet and the second magnet repel each other, and the repulsive force is greater than the gravity of the hinge plate, so the hinge plate is in a horizontal state, and the hinge plate is in a critical state about to rotate.

[0023] When the dry glue enters the collection box with the air flow, the dry glue comes into contact with water. At this time, the dry glue is suspended in the water and gradually settles to the bottom of the water. At this time, since the gas continues to enter the collection box from the catheter, the water in the collection box is easily shaken. During the shaking process, some of the dry glue that has settled at the bottom of the water is suspended again. Due to the strong attraction of the air pump, some of the glue floats to the water surface. The dry glue floating on the water surface is easily extracted by the air pump and discharged to the outside.

[0024] When the dry glue settles to the bottom of the water, it will press the hinge plate downward, and as the amount of dry glue increases, the overall weight of the hinge plate will increase. Therefore, when the hinge plate, which is already in a critical state, is subjected to downward pressure, the hinge plate begins to rotate around the hinge point. When the hinge plate rotates, it will form an angle with the horizontal plane. At this time, the dry glue on the surface of the hinge plate will move downward along the hinge plate. When the dry glue on the surface of the hinge plate falls into the space below the hinge plate, the repulsive force between the first magnet and the second magnet is greater than the gravity of the hinge plate. Therefore, the hinge plate will be in a horizontal state again, thereby preventing the dry glue in the water from being pumped out by the air pump.

[0025] Preferably, the alarm mechanism includes a warning light fixedly mounted on the outer wall of the collection box, a second bracket is movably mounted on the fixed rod, a semipermeable membrane is fixedly mounted on the second bracket, a third spring is mounted on the portion of the fixed rod below the second bracket, and a switch connected in series with the warning light is fixedly mounted on the inner bottom wall of the collection box.

[0026] In the initial state, under the action of the third spring, the second bracket will be pushed upward by the third spring. Since the water flow in the space below the hinged plate in the collection box is stable, when the dry glue falls from the hinged plate, it will directly fall onto the semipermeable membrane. Since only water can pass through the semipermeable membrane, the dry glue will gather on the surface of the semipermeable membrane, thereby increasing the weight of the entire second bracket. When the weight of the second bracket increases, the second bracket will squeeze the third spring and move downward along the fixed rod. When the third spring is squeezed, the second bracket will squeeze the switch, so that the warning light will light up, which serves to remind the staff to clean the collection box in time.

[0027] Preferably, the first output end of the double-headed motor extends into the box body and is vertically fixedly mounted with a mounting rod, and a plurality of stirring blades are evenly fixedly mounted on the mounting rod.

[0028] The stirring blades are driven by a double-headed motor to rotate, and a vortex can be generated in the box when the stirring blades rotate. Under the action of the vortex, the dry glue suspended in the air will rotate with the vortex and then rotate to the bottom of the vortex, so that the dry glue can quickly reach the conduit, thereby preventing the dry glue suspended in the box from passing through the feed port and the discharge port and dissipating to the outside.

[0029] Preferably, the installation rod passes through the conduit and extends into the collection box, and a plurality of thin rods are evenly fixedly installed on the portion of the rotating rod located below the conduit.

[0030] When the air pump is working, the gas in the box enters the collection box through the conduit. When the gas enters the water, it will float up from the bottom of the water in the form of bubbles. At this time, the bubbles are large, so the dry glue will be suspended in the bubbles. The dry glue suspended in the bubbles cannot contact the water. Therefore, when the large bubbles reach the water surface, the dry glue will reach the air in the collection box along with the bubbles, and then be discharged into the air by the air pump and easily inhaled by the staff. Therefore, by driving the thin rod to rotate through the mounting rod, the large bubbles entering the water can be broken up, so that the dry glue in the bubbles can contact the water and settle in the water, which plays a role in preventing the dry glue in the large bubbles from entering the air in the collection box along with the large bubbles and then being discharged into the air by the air pump.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. When the aluminum foil passes through the feed port and enters the box, the first double-headed motor drives the cutter head to rotate rapidly. Since the cutter head cooperates with the edge of the aluminum foil, it will hit the dry glue hanging at the connection between the aluminum foil and the paper when the cutter head rotates rapidly. Since the thickness of the cutter head is relatively thin, the contact area of ​​the cutter head when it contacts the dry glue is relatively small, so the pressure at the contact point is relatively large, so that the hanging dry glue can be cut off to prevent the dry glue hanging on the edge of the aluminum foil from being rolled in when rolling.

[0033] 2. Because the sponge is elastic, it will still fit tightly to the aluminum foil after absorbing the kinetic energy of the aluminum foil, thus preventing the aluminum foil from vibrating over a large range and preventing the aluminum foil from being damaged by the blade due to shaking. The sponge is relatively fluffy, so after absorbing the kinetic energy of the aluminum foil, the fibers of the sponge itself will vibrate, converting the elastic potential energy into internal energy during the shaking process, thus continuously absorbing the kinetic energy of the aluminum foil.

[0034] 3. The air pump is driven by the second double-head motor. Since the air inlet pipe installed on the air inlet of the air pump extends into the collection box, and the collection box is filled with clean water, the air in the space above the water surface in the collection box will be pumped out during the operation of the air pump. When the air is pumped out, the pressure in the space decreases, so the air is absorbed from the box through the conduit to balance the pressure. Therefore, the gas in the box will enter the collection box. Since the cut dry glue is suspended in the air in the box, when the air in the box enters the collection box, the dry glue suspended in the air will also enter it with the air, thereby collecting the dry glue suspended in the box.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] See also Figures 1 to 11 The present invention provides an aluminum-paper composite printing and dyeing machine, and the technical solution is as follows:

[0051] A composite printing and dyeing machine for aluminum paper comprises a first bracket 1, on which a pressing roller 2 and a steering roller 3 are horizontally rotatably mounted, a dryer 4 is fixedly mounted on the first bracket 1, and the dryer 4 is located below the steering roller 3, a box 5 is fixedly mounted on the first bracket 1 at a position below the dryer 4, a feed port and a discharge port are symmetrically provided on the top and bottom walls of the box 5, a first double-headed motor 6 is fixedly mounted in the box 5, a cutter head 7 cooperating with an edge of aluminum foil is mounted on both output ends of the first double-headed motor 6, and a clamping mechanism for limiting the shaking of the aluminum foil is provided in the box 5.

[0052] During the working process, the aluminum foil and paper coated with glue are pressed together after passing through the pressing roller 2 to form aluminum foil paper. Under the action of the turning roller 3, the aluminum foil paper changes from the original horizontal movement to the vertical movement. The glue of the aluminum foil paper moving in the vertical direction will be air-dried when it passes through the dryer 4. Since the aluminum foil and the paper are closely attached during the pressing process, the glue on the surface of the aluminum foil will overflow from the gap between the aluminum foil and the paper. Since the glue is sticky, the overflowed glue will still stick to the glue in the interlayer between the aluminum foil and the paper, that is, the overflowed glue will hang at the bonding point of the aluminum foil and the paper. When passing through the dryer 4, the overflowed glue will also be dried to form dry glue. When the aluminum foil passes through the feed port and enters the box body 5, the first double-headed motor 6 drives the cutter head 7 to rotate rapidly. Since the cutter head 7 cooperates with the edge of the aluminum foil, when the cutter head 7 rotates rapidly, it will hit the dry glue hanging at the connection between the aluminum foil and the paper. Since the thickness of the cutter head 7 is relatively thin, the contact area of ​​the cutter head 7 when in contact with the dry glue is relatively small, so the pressure at the contact point is relatively large, so that the hanging dry glue can be cut off, which prevents the dry glue hanging on the edge of the aluminum foil from being rolled in when winding.

[0053] As an embodiment of the present invention, refer to Figure 4 , Figure 5 and Figure 6 The clamping mechanism includes a first mounting plate 8 vertically fixedly mounted on the side walls of the feed port and the discharge port, two second mounting plates 9 cooperating with the first mounting plate 8 are installed in the box body 5, sponges 10 are fixedly mounted on the side walls on the opposite sides of the first mounting plate 8 and the second mounting plate 9, and an adjustment mechanism cooperating with the second mounting plate 9 is provided in the box body 5.

[0054] Since the first double-headed motor 6 drives the cutter head 7 to cut the dry glue on the edge of the aluminum foil, the dry glue is cut off by the impact force of the edge of the cutter head 7 on the dry glue, and the dry glue and the aluminum foil are connected together. Therefore, at the moment when the cutter head 7 hits the edge of the dry glue, the aluminum foil will shake slightly. When the aluminum foil shakes slightly, since the sponge 10 is in close contact with it, the kinetic energy of the aluminum foil during shaking will be transmitted to the sponge 10. Since the sponge 10 is elastic, it will still fit closely with the aluminum foil after absorbing the kinetic energy of the aluminum foil. Therefore, it can prevent the aluminum foil from shaking over a large range, and prevent the aluminum foil from being damaged by the cutter head 7 due to shaking. In addition, the sponge 10 is relatively fluffy. Therefore, after absorbing the kinetic energy of the aluminum foil, the fibers of the sponge 10 itself will shake, and the elastic potential energy will be converted into internal energy during the shaking process, thereby continuously absorbing the kinetic energy of the aluminum foil.

[0055] As an embodiment of the present invention, refer to Figure 4 The adjustment mechanism includes two groups of slide grooves symmetrically opened on the inner top wall and the inner bottom wall of the box body 5, and the two second mounting plates 9 are movably installed in one group of slide grooves respectively. Guide rods 11 are fixedly installed on the two output ends of the first double-headed motor 6, and guide grooves cooperating with the cutter head 7 are symmetrically opened on the guide rods 11. Blocks 12 are fixedly installed on the ends of the two guide rods 11 away from each other. The cutter head 7 is movably sleeved on the guide grooves, and a first spring 13 is sleeved on the guide rods 11. The two ends of the first spring 13 are fixedly connected to the cutter head 7 and the block 12 respectively. A driving mechanism cooperating with the second mounting plate 9 and the cutter head 7 is provided on the box body 5.

[0056] Since the distance between the first mounting plate 8 and the second mounting plate 9 is the same, and the side walls on the adjacent sides are fixedly mounted with sponges 10, and the sponges 10 on the side walls of the first mounting plate 8 and the sponges 10 on the side walls of the second mounting plate 9 are tightly attached together, when the aluminum foil reaches between the two sponges 10, the pressure on the two surfaces of the aluminum foil is the same, so it can be fixed.

[0057] In the initial state, under the joint action of the first spring 13 and the driving mechanism, the two cutter heads 7 are pushed and move along the two guide grooves respectively, and move to the end where the two guide grooves are close to each other. Since the edge of the cutter head 7 is in contact with the second mounting plate 9, the two second mounting plates 9 are also pushed to the end where the two slide grooves are close to each other. Therefore, when producing aluminum foil of a larger size, the two second mounting plates 9 slide in the slide groove and move away from each other under the action of the driving mechanism, thereby changing the distance between the two second mounting plates 9, so that aluminum foil of different sizes can be clamped. At the same time, the two cutter heads 7 are moved to the end where the two guide grooves are away from each other through the driving mechanism, thereby changing the spacing between the two cutter heads 7, so that the cutter heads 7 can always be in contact with the edge of the aluminum foil, thereby expanding the scope of use.

[0058] As an embodiment of the present invention, refer to Figure 2 , Figure 3 , Figure 4 ,and Figure 8 The driving mechanism includes a first cylinder 14 fixedly mounted in the box body 5, two first piston plates 15 and a second piston plate 16 are movably arranged in the first cylinder 14, first push rods 17 fixedly connected to the two second mounting plates 9 are horizontally fixedly mounted on the side walls of the two first piston plates 15, a second push rod 18 extending to the outside of the box body 5 is horizontally fixedly mounted on the second piston plate 16, a second cylinder 19 is fixedly mounted on the first double-headed motor 6, two third piston plates 20 and a fourth piston plate 21 are movably arranged in the second cylinder 19, and the side walls of the two third piston plates 20 are horizontally fixedly mounted with A third push rod 22 is provided with a groove at one end of the third push rod 22 that contacts the cutter head 7, and a steel ball 23 is movably embedded in the groove. A fourth push rod 24 extending to the outside of the box body 5 is horizontally fixedly installed on the fourth piston plate 21. A threaded rod 25 is horizontally fixedly installed on the outer wall of the box body 5, and a nut 26 is threadedly installed on the threaded rod 25. A fixing plate 27 is movably sleeved on a portion of the threaded rod 25 located between the nut 26 and the box body 5. The second push rod 18 and the fourth push rod 24 are respectively fixedly installed at two ends of the fixing plate 27 at one end extending out of the box body 5, and a second spring 28 is sleeved on a portion of the threaded rod 25 located between the box body 5 and the fixing plate 27.

[0059] In the initial state, the nut 26 is at the end of the threaded rod 25 away from the box body 5, and under the action of the second spring 28, the fixing plate 27 is tightly fitted with the side wall of the nut 26, so the first cylinder 14 and the second cylinder 19 are both in a negative pressure state, so the first piston plate 15 drives the first push rod 17 to retract, and the first push rod 17 drives the two mounting plates to move to one end where the two slide grooves are close to each other, and when the third piston plate 20 drives the third push rod 22 to retract into the second cylinder 19, the cutter head 7 can slide freely along the guide groove, so under the action of the first spring 13, the two cutter heads 7 move to one end where the two guide grooves are close to each other.

[0060] When the distance between the two second mounting plates 9 and the two cutter heads 7 needs to be changed, the nut 26 is screwed to move the nut 26 on the threaded rod 25 and drive the fixing plate 27 to move toward the direction close to the box body 5, and the fixing plate 27 is used to drive the second push rod 18 and the fourth push rod 24 to move. When the second push rod 18 and the fourth push rod 24 move, the second piston plate 16 and the fourth piston plate 21 move along the inner walls of the first cylinder 14 and the second cylinder 19 respectively, thereby increasing the pressure in the first cylinder 14 and the second cylinder 19 respectively. Therefore, the first piston plate 15 and the third piston plate 20 move along the inner walls of the first cylinder 14 and the second cylinder 19 respectively to balance the pressure. When the third push rod 22 moves, it can push the two cutter heads 7 to move along the guide groove and move to one end of the two guide grooves away from each other, thereby changing the distance between the two cutter heads 7, thereby expanding the scope of use. Under the action of the steel ball 23, the sliding friction between the third push rod 22 and the cutter head 7 is converted into rolling friction between the steel ball 23 and the cutter head 7, thereby reducing the friction force and making the rotation of the cutter head 7 smoother.

[0061] As an embodiment of the present invention, refer to Figure 6 A collecting box 29 is fixedly mounted on the bottom wall of the box body 5, and clean water is contained in the collecting box 29. A conduit 30 is fixedly mounted on the bottom wall of the box body 5, and the conduit 30 extends into the collecting box 29. The water surface in the collecting box 29 is located above the conduit 30. A second double-headed motor 31 is fixedly mounted on the top wall of the box body 5, and an air pump 32 is fixedly mounted on the first output end of the second double-headed motor 31. An air inlet pipe 33 is fixedly mounted on the air inlet of the air pump 32, and the air inlet pipe 33 extends into the collecting box 29.

[0062] During operation, the second double-headed motor 31 is started, and the air pump 32 is driven by the second double-headed motor 31. Since the air inlet pipe 33 installed on the air inlet of the air pump 32 extends into the collecting box 29, and the collecting box 29 is filled with clean water, the air in the space above the water surface in the collecting box 29 will be extracted during the operation of the air pump 32. When the air is extracted, the pressure in the space decreases, so the air is absorbed from the box 5 through the conduit 30 to balance the pressure, so the gas in the box 5 will enter the collecting box 29. Since the cut dry glue is suspended in the air in the box 5, when the air in the box 5 enters the collecting box 29, the dry glue suspended in the air will also enter it along with the air, thereby achieving the effect of collecting the dry glue suspended in the box 5.

[0063] As an embodiment of the present invention, refer to Figure 6 A fixing rod 37 is vertically fixed on the inner bottom wall of the collection box 29, and the top of the fixing rod 37 is hinged with two hinged plates 38 that fit tightly with the side walls of the collection box 29. A first magnet 39 is fixedly installed on the fixing rod 37 at a position below the hinged plate 38, and a second magnet 40 that repel each other with the first magnet 39 is fixedly installed on the bottom walls of the two hinged plates 38. An alarm mechanism is provided in the collection box 29.

[0064] In the initial state, the first magnet 39 and the second magnet 40 repel each other, and the repulsive force is greater than the gravity of the hinge plate 38, so the hinge plate 38 is in a horizontal state, and the hinge plate 38 is in a critical state of being about to rotate.

[0065] When the dry glue enters the collecting box 29 with the air flow, the dry glue comes into contact with water. At this time, the dry glue is suspended in the water and gradually settles to the bottom of the water. At this time, since the gas continues to enter the collecting box 29 from the conduit 30, the water in the collecting box 29 is easily shaken. During the shaking process, some of the dry glue that has settled on the bottom of the water is suspended again. Due to the strong attraction of the air pump 32, some of the glue floats to the water surface. The dry glue floating on the water surface is easily extracted by the air pump 32 and discharged to the outside.

[0066] When the dry glue settles to the bottom of the water, it will press the hinge plate 38 downward, and as the amount of dry glue increases, the overall weight of the hinge plate 38 will increase. Therefore, when the hinge plate 38, which is originally in a critical state, is subjected to downward pressure, the hinge plate 38 begins to rotate around the hinge point. When the hinge plate 38 rotates, an angle is formed with the horizontal plane. At this time, the dry glue on the surface of the hinge plate 38 will move downward along the hinge plate 38. When the dry glue on the surface of the hinge plate 38 falls into the space below the hinge plate 38, since the repulsive force between the first magnet 39 and the second magnet 40 is greater than the gravity of the hinge plate 38, the hinge plate 38 will be in a horizontal state again, thereby preventing the dry glue in the water from being sucked out by the air pump 32.

[0067] As an embodiment of the present invention, refer to Figure 6 The alarm mechanism includes a warning light 41 fixedly mounted on the outer wall of the collection box 29, a second bracket 42 is movably mounted on the fixed rod 37, a semipermeable membrane 43 is fixedly mounted on the second bracket 42, a third spring 44 is mounted on the portion of the fixed rod 37 below the second bracket 42, and a switch 45 connected in series with the warning light 41 is fixedly mounted on the inner bottom wall of the collection box 29.

[0068] In the initial state, under the action of the third spring 44, the second bracket 42 will be pushed upward by the third spring 44. Since the water flow in the space below the hinge plate 38 in the collection box 29 is stable, when the dry glue falls from the hinge plate 38, it will directly fall onto the semipermeable membrane 43. Since only water can pass through the semipermeable membrane 43, the dry glue will gather on the surface of the semipermeable membrane 43, thereby increasing the weight of the entire second bracket 42. When the weight of the second bracket 42 increases, the second bracket 42 will squeeze the third spring 44 and move downward along the fixing rod 37. When the third spring 44 is squeezed, the second bracket 42 will squeeze the switch 45, so that the warning light 41 will light up, which serves to remind the staff to clean the collection box 29 in time.

[0069] As an embodiment of the present invention, refer to Figure 6 The first output end of the double-headed motor extends into the box body 5 and is vertically fixedly installed with a mounting rod 34, and a plurality of stirring blades 35 are evenly fixedly installed on the mounting rod 34.

[0070] The stirring blade 35 is driven to rotate by a double-headed motor, and when the stirring blade 35 rotates, a vortex can be generated in the box 5. Under the action of the vortex, the dry glue suspended in the air will rotate with the vortex and then rotate to the bottom of the vortex, so that the dry glue can quickly reach the conduit 30, thereby preventing the dry glue suspended in the box 5 from passing through the feed port and the discharge port and being emitted to the outside.

[0071] As an embodiment of the present invention, refer to Figure 6 The mounting rod 34 penetrates the conduit 30 and extends into the collecting box 29 , and a plurality of thin rods 36 are evenly fixedly mounted on the portion of the rotating rod located below the conduit 30 .

[0072] When the air pump 32 is working, the gas in the box 5 enters the collection box 29 through the conduit 30. When the gas enters the water, it will float upward from the bottom of the water in the form of bubbles. At this time, the bubbles are relatively large, so the dry glue will be suspended in the bubbles. The dry glue suspended in the bubbles cannot contact the water. Therefore, when the large bubbles reach the water surface, the dry glue will reach the air in the collection box 29 together with the bubbles, and then be discharged into the air by the air pump 32, and it is easy to be inhaled by the staff. Therefore, by driving the thin rod 36 to rotate through the mounting rod 34, the large bubbles entering the water can be broken up, so that the dry glue in the bubbles can contact the water and settle in the water, which plays a role in preventing the dry glue in the large bubbles from entering the air in the collection box 29 together with the large bubbles and then being discharged into the air by the air pump 32.

[0073] Working principle: During the working process, the aluminum foil and paper coated with glue are pressed together after passing through the pressing roller 2 to form aluminum foil paper. Under the action of the turning roller 3, the aluminum foil paper changes from the original horizontal movement to the vertical movement. The glue of the aluminum foil paper moving in the vertical direction will be air-dried when it passes through the dryer 4. Since the aluminum foil and the paper are tightly attached during the pressing process, the glue on the surface of the aluminum foil will overflow from the gap between the aluminum foil and the paper. Since the glue is sticky, the overflowed glue will still be in the interlayer between the aluminum foil and the paper. The glue that overflows will stick together, that is, the overflowed glue will hang at the bonding place of the aluminum foil and the paper. When passing through the dryer 4, the overflowed glue will also be dried to form dry glue. When the aluminum foil passes through the feed port and enters the box body 5, the first double-headed motor 6 drives the cutter head 7 to rotate rapidly. Since the cutter head 7 cooperates with the edge of the aluminum foil, when the cutter head 7 rotates rapidly, it will hit the dry glue hanging at the connection place of the aluminum foil and the paper. Since the thickness of the cutter head 7 is relatively thin, the contact area of ​​the cutter head 7 when in contact with the dry glue is relatively small, so the contact The pressure at the point is relatively large, so that the hanging dry glue can be cut off, which plays a role in preventing the dry glue hanging on the edge of the aluminum foil from being rolled into it during winding. Since the first double-headed motor 6 drives the cutter head 7 to cut the dry glue on the edge of the aluminum foil, it relies on the impact force of the edge of the cutter head 7 on the dry glue to cut it off, and the dry glue and the aluminum foil are connected together, so at the moment when the cutter head 7 hits the edge of the dry glue, the aluminum foil will shake slightly. When the aluminum foil shakes slightly, the sponge 10 is in close contact with it, so the aluminum foil shakes The kinetic energy of the aluminum foil will be transferred to the sponge 10. Since the sponge 10 is elastic, it will still fit tightly to the aluminum foil after absorbing the kinetic energy of the aluminum foil. Therefore, it can prevent the aluminum foil from shaking over a large range, and prevent the aluminum foil from being damaged by the blade 7 due to shaking. In addition, the sponge 10 is relatively fluffy. Therefore, after absorbing the kinetic energy of the aluminum foil, the fibers of the sponge 10 itself will shake, and the elastic potential energy will be converted into internal energy during the shaking process, thereby continuously absorbing the kinetic energy of the aluminum foil.

[0074] In the initial state, the nut 26 is at the end of the threaded rod 25 away from the box body 5, and under the action of the second spring 28, the fixing plate 27 is tightly fitted with the side wall of the nut 26, so the first cylinder 14 and the second cylinder 19 are both in a negative pressure state, so the first piston plate 15 drives the first push rod 17 to retract, and the first push rod 17 drives the two mounting plates to move to one end where the two slide grooves are close to each other, and when the third piston plate 20 drives the third push rod 22 to retract into the second cylinder 19, the cutter head 7 can slide freely along the guide groove, so under the action of the first spring 13, the two cutter heads 7 move to one end where the two guide grooves are close to each other.

[0075] When the distance between the two second mounting plates 9 and the two cutter heads 7 needs to be changed, the nut 26 is screwed to move the nut 26 on the threaded rod 25 and drive the fixing plate 27 to move toward the direction close to the box body 5, and the fixing plate 27 is used to drive the second push rod 18 and the fourth push rod 24 to move. When the second push rod 18 and the fourth push rod 24 move, the second piston plate 16 and the fourth piston plate 21 move along the inner walls of the first cylinder 14 and the second cylinder 19 respectively, thereby increasing the pressure in the first cylinder 14 and the second cylinder 19 respectively. Therefore, the first piston plate 15 and the third piston plate 20 move along the inner walls of the first cylinder 14 and the second cylinder 19 respectively to balance the pressure. When the third push rod 22 moves, it can push the two cutter heads 7 to move along the guide groove and move to one end of the two guide grooves away from each other, thereby changing the distance between the two cutter heads 7, thereby expanding the scope of use. Under the action of the steel ball 23, the sliding friction between the third push rod 22 and the cutter head 7 is converted into rolling friction between the steel ball 23 and the cutter head 7, thereby reducing the friction force and making the rotation of the cutter head 7 smoother.

[0076] In the initial state, under the action of the first spring 13, the two second mounting plates 9 are pushed to the end of the slide groove where they are close to each other, and under the action of the second spring 28, the cutter head 7 is guided to the end of the first double-headed motor 6 on the guide groove. Therefore, when producing aluminum foil of larger size, the second mounting plates 9 slide in the slide groove and move away from each other, changing the distance between the two second mounting plates 9, so that aluminum foil of different sizes can be clamped. At the same time, the two cutter heads 7 move to the ends of the two guide grooves where they are away from each other, thereby changing the spacing between the two cutter heads 7, so that the cutter heads 7 can always fit the edge of the aluminum foil, thereby expanding the scope of use.

[0077] In the initial state, the first magnet 39 and the second magnet 40 repel each other, and the repulsive force is greater than the gravity of the hinge plate 38, so the hinge plate 38 is in a horizontal state, and the hinge plate 38 is in a critical state of being about to rotate.

[0078] When the dry glue enters the collecting box 29 with the air flow, the dry glue comes into contact with water. At this time, the dry glue is suspended in the water and gradually settles to the bottom of the water. At this time, since the gas continues to enter the collecting box 29 from the conduit 30, the water in the collecting box 29 is easily shaken. During the shaking process, some of the dry glue that has settled on the bottom of the water is suspended again. Due to the strong attraction of the air pump 32, some of the glue floats to the water surface. The dry glue floating on the water surface is easily extracted by the air pump 32 and discharged to the outside.

[0079] When the dry glue settles to the bottom of the water, it will press the hinge plate 38 downward, and as the amount of dry glue increases, the overall weight of the hinge plate 38 will increase. Therefore, when the hinge plate 38, which is originally in a critical state, is subjected to downward pressure, the hinge plate 38 begins to rotate around the hinge point. When the hinge plate 38 rotates, an angle is formed with the horizontal plane. At this time, the dry glue on the surface of the hinge plate 38 will move downward along the hinge plate 38. When the dry glue on the surface of the hinge plate 38 falls into the space below the hinge plate 38, since the repulsive force between the first magnet 39 and the second magnet 40 is greater than the gravity of the hinge plate 38, the hinge plate 38 will be in a horizontal state again, thereby preventing the dry glue in the water from being sucked out by the air pump 32.

[0080] In the initial state, under the action of the third spring 44, the second bracket 42 will be pushed upward by the third spring 44. Since the water flow in the space below the hinge plate 38 in the collection box 29 is stable, when the dry glue falls from the hinge plate 38, it will directly fall onto the semipermeable membrane 43. Since only water can pass through the semipermeable membrane 43, the dry glue will gather on the surface of the semipermeable membrane 43, thereby increasing the weight of the entire second bracket 42. When the weight of the second bracket 42 increases, the second bracket 42 will squeeze the third spring 44 and move downward along the fixing rod 37. When the third spring 44 is squeezed, the second bracket 42 will squeeze the switch 45, so that the warning light 41 will light up, which serves to remind the staff to clean the collection box 29 in time.

[0081] The stirring blade 35 is driven to rotate by a double-headed motor, and when the stirring blade 35 rotates, a vortex can be generated in the box 5. Under the action of the vortex, the dry glue suspended in the air will rotate with the vortex and then rotate to the bottom of the vortex, so that the dry glue can quickly reach the conduit 30, thereby preventing the dry glue suspended in the box 5 from passing through the feed port and the discharge port and being emitted to the outside.

[0082] When the air pump 32 is working, the gas in the box 5 enters the collection box 29 through the conduit 30. When the gas enters the water, it will float upward from the bottom of the water in the form of bubbles. At this time, the bubbles are relatively large, so the dry glue will be suspended in the bubbles. The dry glue suspended in the bubbles cannot contact the water. Therefore, when the large bubbles reach the water surface, the dry glue will reach the air in the collection box 29 together with the bubbles, and then be discharged into the air by the air pump 32, and it is easy to be inhaled by the staff. Therefore, by driving the thin rod 36 to rotate through the mounting rod 34, the large bubbles entering the water can be broken up, so that the dry glue in the bubbles can contact the water and settle in the water, which plays a role in preventing the dry glue in the large bubbles from entering the air in the collection box 29 together with the large bubbles and then being discharged into the air by the air pump 32.

[0083] During operation, the second double-headed motor 31 is started, and the air pump 32 is driven by the second double-headed motor 31. Since the air inlet pipe 33 installed on the air inlet of the air pump 32 extends into the collecting box 29, and the collecting box 29 is filled with clean water, the air in the space above the water surface in the collecting box 29 will be extracted during the operation of the air pump 32. When the air is extracted, the pressure in the space decreases, so the air is absorbed from the box 5 through the conduit 30 to balance the pressure, so the gas in the box 5 will enter the collecting box 29. Since the cut dry glue is suspended in the air in the box 5, when the air in the box 5 enters the collecting box 29, the dry glue suspended in the air will also enter it along with the air, thereby achieving the effect of collecting the dry glue suspended in the box 5.
