Description

Technical Field

[0001] The invention relates to the technical field of packaging printing technology, and in particular to a solvent-free laminating machine. Background Art

[0002] Solvent-free laminating machine is a method of laminating two or more substrates together using solvent-free adhesives, also known as reactive laminating. Solvent-free laminating machines used at home and abroad are mostly two-layer laminating and single-station unwinding and winding structures. Its main components are: first unwinding unit, coating unit, second unwinding unit, laminating unit, and winding unit.

[0003] After searching, the patent with publication number CN209381544U discloses a solvent-free laminating machine. The device is provided with a first coating back pressure group between the coating unit and the first correcting unit, and a second coating back pressure group between the second unwinding unit and the second correcting unit. The first coating back pressure group and the second coating back pressure group adopt coating back pressure steel rollers with water cooling. The heat is evenly reduced by water cooling, and the precision problem of the coating back pressure steel roller caused by thermal expansion and contraction is reduced, thereby accelerating the cooling effect of the composite film and improving production efficiency.

[0004] Although the existing device can effectively improve production efficiency during use, the staff needs to regularly prepare the solvent-free adhesive and add it to the device. The operation of the device must be stopped during the adding process, which will lead to a decrease in production speed. In addition, the preparation method of the solvent-free adhesive will vary depending on the production process, which will not only greatly increase the difficulty of operation, but also various raw materials must be weighed each time they are prepared, further increasing the operating burden of the staff. In view of this, we propose a solvent-free laminating machine. Summary of the invention

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0034] A solventless laminating machine comprises a solventless laminating machine body 1, a shell 2 is arranged on the left side of the solventless laminating machine body 1, the shell 2 is in an L-shaped structure, a pump body 3 is arranged between the shell 2 and the solventless laminating machine body 1, two conduits 4 are symmetrically connected at both ends of the pump body 3, the conduit 4 on the right side is connected to the solventless laminating machine body 1, and the end of the conduit 4 on the right side is connected to the input port of the component storing the solventless adhesive on the solventless laminating machine body 1, so that the solventless adhesive prepared by the device can be input into the solventless laminating machine body 1 for use through the pump body 3, and a plurality of raw material slots 5 are opened on the top surface of the left side of the shell 2 in an equidistant structure, and the raw material slots 5 is an L-shaped structure, and the staff can put various raw materials required for preparing the solvent-free adhesive into different raw material grooves 5 respectively. A roller 6 is arranged between the lower right parts of the multiple raw material grooves 5, and an inner cavity 7 is opened on the front wall of the shell 2 relative to the position of the roller 6. The roller 6 and the inner cavity 7 are rotated together, and the roller 6 can rotate in the inner cavity 7. The outer wall of the roller 6 is a linear equidistant structure and is sleeved with multiple sealing rings 8. The top surface of the roller 6 is provided with a cavity 9 relative to the position between two adjacent sealing rings 8. A material dividing barrel 10 is arranged inside the cavity 9. The positions of the multiple material dividing barrels 10 correspond to the positions of the multiple raw material grooves 5 one by one, and the raw materials in the raw material grooves 5 can enter the corresponding material dividing barrels 10.

[0035] Specifically, two discharging grooves 11 are symmetrically provided on the left and right sides of the discharging barrel 10, and the diameters of the multiple discharging grooves 11 on the same side are reduced in sequence from front to back. Through such a structure, different amounts of raw materials taken out of different discharging barrels 10 after rotating half a circle are also different, and then different raw materials are taken out in proportion according to the size ratio of each discharging groove 11, which is convenient for the staff to prepare solvent-free adhesives. A baffle 12 is fixedly provided on the top surface of the discharging barrel 10, and the outer wall of the baffle 12 is an arc surface structure with an arc equal to the outer wall of the drum 6. The outer wall of the baffle 12 is in sliding contact with the inner wall of the inner cavity 7. Under such a structure, the raw material will not leak from the gap between the top surface of the discharging barrel 10 and the inner cavity 7, and The baffles 12 fixed on each distributing barrel 10 with discharging troughs 11 of different sizes will also change in accordance with the discharging troughs 11 to prevent the baffle 12 from being too large and affecting the raw materials from entering the discharging trough 11. A connecting groove 13 is provided on the right side of the inner cavity 7 of the baffle 12 relative to the position of the discharging trough 11 on the right side. After the drum 6 drives the distributing barrel 10 to rotate half a circle, the raw materials in the discharging trough 11 will slide to the right along the connecting groove 13. A sealing groove 14 is provided on the inner wall of the inner cavity 7 relative to the position of the sealing ring 8. The sealing ring 8 rotates with the sealing groove 14 to seal the joint between the drum 6 and the inner cavity 7, thereby preventing the raw materials in the two adjacent raw material troughs 5 from mixing with each other.

[0036] Furthermore, a limit block 15 is fixedly provided in the middle part of the bottom surface of the cavity 9, and a limit groove 16 is provided on the bottom surface of the distribution barrel 10 relative to the position of the limit block 15, and the limit block 15 is plugged into the limit groove 16, and a limit rod 17 is provided between the upper parts of multiple distribution barrels 10. The limit rod 17 is a T-shaped structure, and a rod groove 18 is provided at the upper part of the distribution barrel 10 and the upper part of the roller 6 relative to the limit rod 17. The limit rod 17 is plugged into the rod groove 18, and an external thread 19 is provided at the rear end of the outer wall of the limit rod 17. A thread groove 20 is provided on the rear wall of the cavity 9 at the rear end relative to the position of the limit rod 17, and the external thread 19 is threadedly connected with the thread groove 20. Under such a design, the staff can replace the distribution barrel 10, thereby changing the size of the discharge trough 11, so that the operation of preparing solvent-free adhesives with different ratios can be completed more flexibly.

[0037] Furthermore, a gear 21 is coaxially fixedly connected to the rear end of the drum 6, and the rear part of the inner cavity 7 is arranged in a T-shaped structure relative to the position of the gear 21. A turntable 22 is arranged above the gear 21. The outer wall of the circumference of the turntable 22 is an arc-shaped structure with equal spacing and a plurality of tooth columns 23 are fixedly arranged symmetrically at the center. The tooth columns 23 are meshed and connected with the gear 21. The plurality of tooth columns 23 located on the same side can drive the gear 21 to rotate 180 degrees. Then, before the plurality of tooth columns 23 on the other side mesh with the gear 21, the gear 21 will pause for a period of time because there is no external force. In this way, the drum 6 can be rotated intermittently, and the discharge trough 11 corresponding to the raw material trough 5 can be rotated to the connecting trough 13 each time, so that the discharge trough 11 has enough time each time. The connecting groove 13 is filled with raw materials or the raw materials are unloaded into the connecting groove 13. A movable groove 24 is provided inside the outer shell 2 relative to the position of the turntable 22 and the gear column 23. The outer wall of the turntable 22 and the outer wall of the gear column 23 are in sliding contact with the inside of the movable groove 24. A motor A25 is coaxially provided at the rear of the outer shell 2 relative to the position of the turntable 22. A through hole 26 is provided on the rear wall of the outer shell 2 relative to the position of the output end of the motor A25. The output end of the motor A25 extends through the through hole 26 to the inside of the movable groove 24 and slides with the through hole 26. The output end of the motor A25 extends through the rear wall of the turntable 22 to the front side and is coaxially fixedly connected to the turntable 22. The motor A25 can drive the turntable 22 to rotate, thereby causing the gear 21 and the drum 6 to move.

[0038] Furthermore, two sliders 27 are symmetrically fixed to the front wall of the motor A25, and a slide groove 28 is provided on the rear wall of the housing 2 relative to the position of the slider 27. The slider 27 and the slide groove 28 are both L-shaped structures and slide in cooperation. Under such a structure, the motor A25 can maintain a horizontal state no matter how it moves up and down, thereby ensuring that the motor A25 can continuously drive the turntable 22 to rotate. Two guide blocks 29 are symmetrically sleeved on the output end of the motor A25 relative to the front and rear sides of the turntable 22, and a guide groove 30 is provided on the inner wall of the movable groove 24 relative to the position of the guide block 29. The guide block 29 slides in cooperation with the guide groove 30, and two connecting rods 31 are symmetrically provided between the top surface of the guide block 29 and the top surface of the guide groove 30 in an eight-shaped structure. The outer ends of the upper and lower connecting rods 31 on the same side are respectively hinged to the top surface of the guide groove 30 and the top surface of the guide block 29, and the inner ends of the two connecting rods 31 on the same side are hinged to each other through a hinge seat 32, and the hinge seat 32 is a U-shaped structure.

[0039] Furthermore, a telescopic rod 33 is provided between the two connecting rods 31 on the same side, and a compression spring 34 is sleeved on the lower end of the outer wall of the telescopic rod 33. Under the elastic force of the compression spring 34, the angle between the two connecting rods 31 will remain unchanged, and at the same time, the position of the turntable 22 will be maintained at the lowest side of the movable groove 24. A through groove 35 is provided on the right wall of the movable groove 24 relative to the right end of the hinge seat 32. The right end of the hinge seat 32 extends to the outside through the through groove 35 and slidably cooperates with the through groove 35. If the hinge seat 35 slides to the left along the through groove 35, the inner ends of the two connecting rods 31 will be pushed to the left synchronously, but the lengths of the two cannot change and the guide block 29 and the guide groove Under the restriction of 30, the turntable 22 cannot be offset, so the angle between the inner ends of the two connecting rods 31 will be reduced under the extrusion, and the telescopic rod 33 will also be shortened synchronously, so that the turntable 22 will be lifted upward, and then the tooth column 23 will be disengaged from the meshing connection with the gear 21. At this time, the motor A25 can only drive the turntable 22 to rotate and no longer affect the gear 21 and the roller 6. An extrusion plate 36 is fixed between the right ends of the two hinged seats 32. The extrusion plate 36 is an L-shaped structure. A plate groove 37 is provided on the top surface of the right side of the shell 2 relative to the lower part of the extrusion plate 36. The lower part of the extrusion plate 36 slides with the plate groove 37, and an extrusion groove 38 is provided on the top surface of the right end of the extrusion plate 36.

[0040] It is worth mentioning that a cylinder 39 is penetrated through the left part of the top surface of the right side of the shell 2. Two guide plates 40 are fixedly arranged at the upper and lower ends of the cylinder 39 in a centrally symmetrical structure. The guide plate 40 on the left side is a U-shaped structure, and the guide plate 40 on the right side is a rectangular cover-like structure with a concave surface to the left. The interiors of the two guide plates 40 are both connected to the interior of the cylinder 39. The guide plate 40 on the left side is embedded in the lower side of the interior of the shell 2. A guide groove 41 is provided in the interior of the shell 2 at a position between the open end of the guide plate 40 on the left side and the plurality of connecting grooves 13. The guide groove 41 is an isosceles trapezoidal column structure with a left-higher-and-right-lower inclined surface on the bottom surface. The raw materials entering the connecting groove 13 from the discharge groove 11 will enter the guide plate 40 along the guide groove 41 and finally merge into the interior of the cylinder 39. A rotating shaft 42 is coaxially fixedly connected to the interior of the cylinder 39. The upper end of the rotating shaft 42 penetrates The motor B50 is coaxially fixedly connected to the inner top surface of the cylinder 39 and extends to the outside. The bottom surface of the motor B50 is fixedly connected to the top surface of the cylinder 39. The outer wall of the rotating shaft 42 is sleeved with an auger blade 43. The outer wall of the auger blade 43 is in sliding contact with the inner wall of the cylinder 39. The middle part of the auger blade 43 is an annular structure with equal spacing and is evenly penetrated by a plurality of stirring plates 44. The stirring plates 44 are arranged in an inclined structure. Under the drive of the rotating shaft by the motor B50, the auger blade 43 and the stirring plate 44 will rotate synchronously. The auger blade 43 will produce the effect of a screw feeder to transport the mixture of various raw materials to the upper guide plate 40, and the multiple inclined stirring plates 44 will mix the raw materials during the rising process, so that the various raw materials are mixed evenly before entering the upper guide plate 40 to form a solvent-free adhesive.

[0041] It is worth noting that a vertical groove 45 is further provided on the top surface of the right side of the shell 2, and the rear part of the vertical groove 45 is connected to the right part of the plate groove 37. The bottom surface of the vertical groove 45 is arranged in a rectangular shape and fixed with a plurality of return springs 46. A support plate 47 is fixed between the upper ends of the plurality of return springs 46. The support plate 47 is slidably matched with the vertical groove 45, and the rear part of the bottom surface of the support plate 47 is extrusion-matched with the extrusion groove 38. A box body 48 is fixed on the top surface of the support plate 47, and a feed pipe 49 is penetrated at the left end of the top surface of the box body 48. The left end of the feed pipe 49 penetrates the right wall of the guide plate 40 located on the right and extends to the inside thereof. The mixed and prepared solvent-free adhesive will enter the inside of the box body 48 along the feed pipe 49. As the amount of solvent-free adhesive in the box body 48 increases, its weight will also suppress the reset. The spring 46 is shortened, and the weight-induced shortening effect of the return spring 46 is reduced during the gradual shortening process. Therefore, when the inside of the box body 48 is close to being fully loaded, the bottom surface of the support plate 47 will produce an extrusion effect on the extrusion groove 38, thereby causing the extrusion plate 36 to move to the left along the plate groove 37, and then the hinge seat 32 will have an impact on the connecting rod 31 and eventually cause the tooth column 23 to disengage from the gear 21. With this design, the device can automatically stop preparing the solvent-free adhesive when the inside of the box body 48 is close to being fully loaded, and there is still enough space inside the box body 48 to accommodate the residual solvent-free adhesive in the feed pipe 49. The left end of the left conduit 4 passes through the right part of the top surface of the box body 48 and extends to the lower side of the inside thereof.
