Description

Technical Field

[0001] The present invention relates to the technical field of film laminating machines, and more particularly to a plastic film laminating device. Background Art

[0002] Online laminator is an automated equipment used in continuous production lines, mainly used to laminate products. Unlike traditional offline laminators, online laminators are usually directly integrated with the production line, which can laminate products while they are being produced, thereby improving production efficiency and reducing production costs.

[0003] Online laminating machines usually include automatic feeding system, laminating device, heating system, cooling system, cutting system, etc. Its working principle is similar to that of offline laminating machines, that is, the film material is stretched and heated from the roll, then covered on the product surface through rollers and other devices, and finally cooled and cut.

[0004] Double-sided lamination of plastic waste is a process of surface treatment of plastic waste through lamination technology, which is usually used to improve the performance, appearance or functionality of waste, thereby improving the recycling of plastic waste. Before lamination, plastic waste can usually be pre-processed into plastic plates. The laminating machine performs lamination during the transportation of the plastic plate, but the traditional laminating machine can only cover a single-sided film, and usually both sides of the plastic plate need to be protected by lamination. This requires workers to stop the plastic plate in time after the laminating machine covers one side of the film, and then either automatically or manually cut the film, and then turn the plastic plate over and pass it through the laminating machine again. This laminating method greatly increases labor costs and strength, increases the risk of errors, and each plastic plate needs to be laminated twice to complete, thereby increasing production time and reducing production efficiency. Therefore, it is necessary to propose a plastic laminating device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0035] Example 1

[0036] See also Figure 1-18 As shown, the present invention discloses a plastic film coating device, including a film coating frame 1, on which a direction-changing mechanism 5 for changing the surface of a plate body 3 is installed, and the direction-changing mechanism 5 includes a direction-changing gear 52 and a buckle 54, the direction-changing gear 52 is rotatably connected to the inner side of the film coating frame 1, and the buckle 54 is slidably connected to the inner side of the film coating frame 1, and the buckle 54 is sleeved on the outer side of the direction-changing gear 52; The inner side of the film-coating frame 1 is also provided with a receiving mechanism 6 for placing the plate body 3, and the receiving mechanism 6 includes a groove body 61, a push plate 64, a return spring 65, a connecting cavity 66, a connecting tooth plate 67, a transmission belt 69 and a propulsion block 691. One end of the groove body 61 is rotatably connected to the inner side of the film-coating frame 1 with the direction-changing gear 52 as the axis, and the plate body 3 is slidably connected to the inside of the groove body 61, the push plate 64 is slidably connected to the inner side of the groove body 61, one end of the return spring 65 is installed on the inner side of the groove body 61, and the other end of the return spring 65 is installed on the push plate 64. The connecting cavity 66 is provided at one end of the groove body 61, and the buckle 5 4 goes deep into the connection cavity 66, the connection tooth plate 67 is slidably connected to the inside of the connection cavity 66, the connection tooth plate 67 is between the buckle ring 54 and the direction-changing gear 52, and the inner side of the buckle ring 54 contacts the outer side of the connection tooth plate 67, the transmission belt 69 is rotatably connected to the inside of the groove body 61, and the push plate 64 is fixed to the bottom side of the transmission belt 69, the two pushing blocks 691 are respectively fixed to the side of the push plate 64 and the top surface of one end of the transmission belt 69, and the pushing blocks 691 on the push plate 64 and the pushing blocks 691 on the transmission belt 69 do not touch each other.

[0037] When the laminating mechanism 4 performs laminating operation on the top surface of the plate body 3, the plate body 3 is pushed into the groove body 61 by the rotation friction of the laminating roller 43. While being pushed in, the plate body 3 drives the push plate 64 to slide, and the push plate 64 stretches the return spring 65 until the push plate 64 slides to the left end of the groove body 61 (see the attached diagram). Figure 3 , the same below). During this process, the push plate 64 drives the push block 691 to move toward the direction of the direction-changing gear 52 through the transmission belt 69. When the push plate 64 moves to the left end, the push block 691 moves to the other end of the transmission belt 69, contacts and pushes the buckle ring 54 to move in the connecting cavity 66. The buckle ring 54 pushes the connecting tooth plate 67 to move, so that the connecting tooth plate 67 is meshed and connected with the direction-changing gear 52. At this point, under the pressure of the buckle ring 54, the groove body 61 is combined with the direction-changing gear 52 through the connecting tooth plate 67 to form a whole. Then the second motor 51 drives the direction-changing gear 52 to rotate, thereby driving the entire receiving mechanism 6 to rotate 180 degrees, and the receiving mechanism 6 flips the internal plate body 3. During the flipping process of the plate body 3, the film continues to cover the plate body 3. After rotating 180 degrees, the left and right ends of the groove body 61 switch directions, and the push plate 64 inside it changes to the end away from the direction-changing gear 52 (the right end of the groove body 61). Under the pulling force of the return spring 65 driving the push plate 64 to slide and the rotation friction of the coating roller 43, the push plate 64 slides in the direction close to the direction-changing gear 52 (the left end of the groove body 61), so that the plate body 3 inside the groove body 61 continues to slide to the left (according to the attached Figure 1 ), the plate body 3 slides out from the inside of the groove body 61, so that the other side of the plate body 3 is also covered with a film.

[0038] During the sliding of the push plate 64 to the left (according to the attached Figure 3 The same applies below), in the same manner as above, the push plate 64 drives another push block 691 on its side to move to the left, and at the same time drives the transmission belt 69 to rotate to the right, so that the push block 691 that originally abuts against the buckle 54 follows the transmission belt 69 away from the direction-changing gear 52, and finally the push block 691 on the side of the push plate 64 makes the receiving mechanism 6 and the direction-changing gear 52 combine into a whole again in the same manner, and the second motor 51 is started again, driving the entire receiving mechanism 6 back to the initial position through the direction-changing gear 52.

[0039] Example 2

[0040] This embodiment is an explanation based on the embodiment 1. For details, please refer to Figure 1-Figure 18 A reeling mechanism 2 is installed at one end of the laminating frame 1, and the reeling mechanism 2 includes a bracket 21, a first motor 22 and a reeling roller 23. The two brackets 21 are symmetrically installed at one end of the laminating frame 1, and the first motor 22 is installed on the surface of one of the brackets 21. The reeling roller 23 rotates between the two brackets 21, and one end of the reeling roller 23 is installed at the output end of the first motor 22.

[0041] A laminating mechanism 4 is also installed on the laminating frame 1, and the laminating mechanism 4 includes a shell 41, a laminating motor 42, a laminating roller 43, a lifting tooth 44, an adjusting gear 45, a connecting rod 46 and an empty slot 47. The two shells 41 are symmetrically installed on the laminating frame 1, and the laminating motor 42 is slidably connected inside the shell 41. A lifting tooth 44 is provided on one side of the laminating motor 42. The laminating roller 43 is rotatably connected between the two shells 41, and the two ends of the laminating roller 43 are respectively installed on the output ends of the two laminating motors 42. The adjusting gear 45 is installed on one side of the shell 41, and the adjusting gear 45 passes through the side of the shell 41 and is meshed with the lifting tooth 44. The surface of the laminating frame 1 is provided with an empty slot 47, one end of the connecting rod 46 is eccentrically connected to the adjusting gear 45, and the other end of the connecting rod 46 swings in the empty slot 47.

[0042] A lifting mechanism 7 is also installed on the inner side of the coating frame 1, and the lifting mechanism 7 includes a limiting groove 71, a rack 72, a slider 73, a locking block 74, a limiting tooth 75 and a fourth spring 76. A limiting groove 71 is provided on the inner side of the coating frame 1, and a rack 72 is provided on the bottom surface of the limiting groove 71. The slider 73 is slidably connected to the inside of the limiting groove 71, and the other end of the connecting rod 46 is rotatably connected to the side surface of the slider 73. The locking block 74 is slidably connected to the bottom of the slider 73, and the side end of the locking block 74 protrudes from the limiting groove 71. The side end of the locking block 74 cooperates and contacts with the second push block 694. A limiting tooth 75 is provided at the bottom of the locking block 74, and the limiting tooth 75 is meshed and connected with the rack 72. The fourth spring 76 is installed inside the slider 73, and one end of the fourth spring 76 is installed on the top surface of the locking block 74.

[0043] The first motor 22 drives the unwinding roller 23 to rotate, releasing the film, and one end of the film is led to the coating roller 43. The coating motor 42 drives the coating roller 43 to rotate continuously, and cooperates with the unwinding roller 23 to cover the film on the plate body 3. The film enters from the top of the coating roller 43, changes direction, and moves from the bottom to the left (according to the attached Figure 1 In order to prevent the coating roller 43 from getting stuck on the top surface of the plate body 3 during the process of the receiving mechanism 6 driving the plate body 3 to rotate around the direction-changing gear 52 as the rotation axis, a lifting mechanism 7 is provided. In a natural state, the elastic force of the fourth spring 76 inside the slider 73 causes the locking block 74 to sink, and the limiting tooth 75 on the bottom surface of the locking block 74 is always meshed and connected with the rack 72 in the limiting groove 71, so that the entire lifting mechanism 7 cannot move, and the coating mechanism 4 connected to the lifting mechanism 7 through the connecting rod 46 will not move. When the push plate 64 inside the groove body 61 slides to the left end, the second push block 694 fixedly connected to the push plate 64 just contacts the locking block 74 protruding from the inner side of the coating frame 1. Since the second push block 694 and the inclined surfaces at the ends of the locking block 74 cooperate with each other and squeeze each other, a force can be generated to make the locking block 74 move upward. The locking block 74 moves upward, and the limiting tooth 75 separates from the rack 72. Then the second push block 694 continues to move to the left, which can push the entire lifting mechanism 7 to slide to the left and pull the connecting rod 46 to swing. The connecting rod 46 is eccentrically connected to the adjusting gear 45, which can drive the adjusting gear 45 to rotate, and then the coating motor 42 is driven to rise in the shell 41 through the lifting gear 44, and finally the coating roller 43 is lifted to a certain height, thereby preventing the coating roller 43 from blocking the plate body 3 from flipping.

[0044] Example 3

[0045] This embodiment is an explanation based on the embodiment 1. For details, please refer to Figure 1-Figure 18 The direction-changing mechanism 5 also includes a second motor 51, a box body 53, a first spring 55, a connecting plate 56, a second spring 57 and a pressure head 58. The second motor 51 is installed on the outside of the laminating frame 1, and the direction-changing gear 52 passes through the laminating frame 1 and is fixedly connected to the output end of the second motor 51. The box body 53 is fixed to the inner side of the laminating frame 1, and the direction-changing gear 52 passes through the center of the box body 53. The first spring 55 is installed inside the box body 53. The buckle 54 is slidably connected to the surface of the box body 53, and one end of the first spring 55 is installed on the buckle 54. The connecting plate 56 with a mouth-shaped structure is installed inside the box body 53. Three pressure heads 58 are respectively fixed to the middle of each side of the connecting plate 56, and the buckle 54 contacts the pressure heads 58 at both ends of the connecting plate 56. A plurality of second springs 57 are installed on the back of the connecting plate 56.

[0046] The receiving mechanism 6 also includes rollers 62, slide grooves 63, third springs 68, shift blocks 692, first push blocks 693 and second push blocks 694. Several rollers 62 are installed on the inner side of the groove body 61. The plate body 3 is slidably connected to the rollers 62. A slide groove 63 is provided on the inner side of the groove body 61, and the push plate 64 is slidably connected to the inside of the slide groove 63. The third spring 68 is installed inside the groove body 61, and the third spring 68 is installed on the outer side of the connecting tooth plate 67. Shift blocks 692 are provided on the surface of the pushing blocks 691, and the shift blocks 692 resist the pressure head 58 in the middle of the connecting plate 56. The first push block 693 is fixed on the push plate 64, and the first push block 693 slides in the middle of the transmission belt 69. The second push block 694 is fixed on the top of the first push block 693.

[0047] When the plate body 3 enters the groove body 61, it pushes the push plate 64 to slide, and the push plate 64 stretches the return spring 65 until the push plate 64 slides to the left end of the groove body 61. During this process, the push plate 64 drives the transmission belt 69 to rotate in the direction of the direction-changing gear 52, and the transmission belt 69 drives the push block 691 on its top surface to move to the right. At the same time, the push plate 64 synchronously drives the first push block 693 and the second push block 694 to slide. The push plate 64 drives the push block 691 to move in the direction close to the direction-changing gear 52 through the transmission belt 69. When the push plate 64 moves to the left end, the push block 691 moves to the other end of the transmission belt 69, contacts and pushes the buckle ring 54 to move in the connecting cavity 66. The buckle ring 54 compresses the first spring 55 and pushes the connecting tooth plate 67 to move, so that the connecting tooth plate 67 is meshed and connected with the direction-changing gear 52. Before the push block 691 contacts the buckle ring 54, the shift block 692 on its surface contacts the pressure head 58 on the left side of the box body 53, pressing all the pressure heads 58 into the box body 53, thereby releasing the blocking of the pressure heads 58 on the buckle ring 54, allowing the buckle ring 54 to slide. When the buckle ring 542 completely presses the connecting tooth plate 67, the upper and lower ends of the buckle ring 54 just pass over the corresponding pressure heads 58 of the connecting plate 56. At this point, under the pressure of the buckle ring 54, the groove body 61 is combined with the direction-changing gear 52 through the connecting tooth plate 67 to form a whole.

[0048] Then the second motor 51 drives the direction-changing gear 52 to rotate, thereby driving the entire receiving mechanism 6 to rotate 180 degrees, and the receiving mechanism 6 flips the internal plate body 3; after the push block 691 that resists the buckle ring 54 inside the groove body 61 rotates, the shift block 692 on its surface releases the pressure head 58, and under the push of the fifth spring 84, the connecting plate 56 drives the pressure head 58 to pop out from the box body 53, resist the buckle ring 54, so that the buckle ring 54 cannot return, ensuring that the buckle ring 54 can always press the connecting tooth plate 67 during the rotation of the entire receiving mechanism 6. During the flipping of the plate body 3, the film continues to cover the plate body 3. When the groove body 61 is about to rotate 180 degrees, the groove body 61 will squeeze the support block 81 on the inner long rod 83 of the laminating frame 1, and press the support block 81 into the laminating frame 1, so that the groove body 61 can successfully complete the 180-degree rotation.

[0049] After rotating 180 degrees, the left and right ends of the slot body 61 switch directions, and the push plate 64 inside it changes to the end away from the direction-changing gear 52 (the right end of the slot body 61), and the shift block 692 on the push block 691 close to the direction-changing gear 52 presses all the pressure heads 58 on the right side of the buckle ring 54 into the box body 53. In this way, the buckle ring 54 is reset under the tension of the first spring 55, releasing the connecting tooth plate 67, and the connecting tooth plate 67 is no longer engaged with the direction-changing gear 52. At the same time, under the tension of the reset spring 65 driving the push plate 64 to slide and the rotation friction of the coating roller 43, the push plate 64 slides in the direction close to the direction-changing gear 52 (the left end of the slot body), causing the plate body 3 inside the slot body 61 to continue to slide to the left (according to the attached Figure 1 ), the plate body 3 slides out from the inside of the groove body 61, so that the other side of the plate body 3 is also covered with a film.

[0050] During the sliding of the push plate 64 to the left (according to the attached Figure 3 The same applies below), in the same manner as above, the push plate 64 drives another push block 691 on its side to move to the left, and at the same time drives the transmission belt 69 to rotate to the right, so that the push block 691 that originally abuts against the buckle 54 follows the transmission belt 69 away from the direction-changing gear 52, and finally the push block 691 on the side of the push plate 64 makes the receiving mechanism 6 and the direction-changing gear 52 combine into a whole again in the same manner, and the second motor 51 is started again, driving the entire receiving mechanism 6 back to the initial position through the direction-changing gear 52.

[0051] Example 4

[0052] This embodiment is an explanation based on the embodiment 1. For details, please refer to Figure 1-Figure 18 A locking mechanism 8 is installed inside the coating frame 1, and the locking mechanism 8 includes a support block 81, a release block 82, a long rod 83 and a fifth spring 84. The support block 81 is slidably connected to the inner side of the coating frame 1, and the support block 81 abuts against the groove body 61. The release block 82 is fixed to the top of the support block 81, and the release block 82 abuts against the first push block 693. A long rod 83 is installed inside the coating frame 1, and the support block 81 and the release block 82 are respectively fixed at both ends of the long rod 83. A plurality of fifth springs 84 are installed inside the coating frame 1, and the support block 81 and the long rod 83 abut against the fifth spring 84 respectively.

[0053] A supporting mechanism 9 is installed at the other end of the coating frame 1, and the supporting mechanism 9 includes a base plate 91, a supporting platform 92, a cylinder body 93, a telescopic rod 94 and a conveying frame 95. The base plate 91 is fixed to the other end of the coating frame 1, and a supporting platform 92 is fixed on the base plate 91. The top surface of the supporting platform 92 is installed with a cylinder body 93, and two telescopic rods 94 are symmetrically installed on the side of the cylinder body 93. The conveying frame 95 is installed at the end of the telescopic rod 94. The plate body 3 is slidably connected to the top surface of the conveying frame 95, and the conveying frame 95 is slidably connected in the coating frame 1.

[0054] When the receiving mechanism 6 is in a horizontal position, the supporting mechanism 8 can limit the rotation of the trough body 61, ensuring that the receiving mechanism 6 is in a horizontal position and improving stability. The receiving mechanism 6 is on the left side of the coating roller 43. When the push plate 64 moves to the left side of the trough body 61, the first push block 693 presses the release block 82 into the coating frame 1 (the first push block 693 squeezes the release block 82 directly connected to the support block 81). The release block 82 compresses the fifth spring 85 and drives the support block 81 connected thereto to enter the coating frame 1, releasing the support of the trough body 61 by the support block 81; after the receiving mechanism 6 drives the plate body 3 to flip, when the push plate 64 moves to the left side of the trough body 61, the first push block 693 thereon squeezes the release block 82 at the end of the long rod 83, and presses the support block 81 at the other end of the long rod 83 into the coating frame 1, releasing the support for the trough body 61.

[0055] The cooperation between the cylinder body 93 and the telescopic rod 94 can transport the new plate body 3 to the coating frame 1 through the conveying frame 95, so that the plate body 3 is coated by the coating mechanism 4 and provides reliable support for the plate body 3 during the coating process; when the receiving mechanism 6 drives the plate body 3 to start flipping, the telescopic rod 94 drives the conveying frame 95 to return immediately, thereby avoiding blocking the flipping of the receiving mechanism 6.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
