Description

Technical Field

[0001] The invention relates to the technical field of glass wool board production, and in particular to automatic film pasting and packaging production equipment for glass wool boards and a production method thereof. Background Art

[0002] As a highly efficient thermal insulation material, glass wool board is widely used in the fields of construction, industrial equipment, etc. In the production process of glass wool board, applying protective film on the surface is a key process before packaging the finished product. Its function is to prevent the surface of the board from being contaminated or damaged during transportation and storage. However, in the existing technology, there are still significant technical bottlenecks in the film application and subsequent packaging process of glass wool board, which restricts the improvement of production efficiency and product consistency.

[0003] In traditional processes, the film laminating operation of glass wool boards mainly relies on manual work. Specifically, workers need to sort out individual sheets from the stacked glass wool boards one by one, and manually carry them to the film laminating station for single-sided lamination. In this process, manual loading is not only labor-intensive and inefficient, but also prone to misalignment of sheets or waste of film materials due to operational errors. It is worth noting that although existing semi-automatic equipment can realize the mobile lamination of glass wool boards through conveyor lines, it can usually only laminarize a single surface of the sheet. After the first side of the film is completed, it is necessary to manually flip the surface without the film to the processing position or add a secondary positioning mechanism before the second film lamination is performed. This step-by-step film laminating mode not only requires additional flipping processes and equipment space, but also prolongs the processing cycle due to repeated positioning, while increasing the risk of scratches on the sheet surface caused by multiple contacts.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 8 As shown, the present invention is an automatic film laminating and packaging production equipment for glass wool boards, comprising a first conveyor belt 1 and a second conveyor belt 2, a frame 3 is provided at one end of the first conveyor belt 1, a loading mechanism 5 for lifting the glass wool board 4 and pushing it onto the first conveyor belt 1 is installed on the frame 3, and a film laminating mechanism 6 is provided between the first conveyor belt 1 and the second conveyor belt 2; the film laminating mechanism 6 comprises a discharge roller 61, a guide roller 62, an upper adsorption roller 63, a lower adsorption roller 64 and a negative pressure lifting mechanism 65, the film body 10 wound on the upper discharge roller 61 is connected to the upper adsorption roller 63 after bypassing the upper guide roller 62, the film body 10 wound on the lower discharge roller 61 is connected to the lower adsorption roller 64 after bypassing the lower guide roller 62, the negative pressure lifting mechanism 65 is connected to the upper adsorption roller 63 and the lower adsorption roller 64, and the negative pressure lifting mechanism 65 is used to control the upper adsorption roller 63 and the lower adsorption roller 64 to adsorb the film body 10.

[0036] It should be noted that, when in use, the stacked glass wool boards 4 are placed on the feeding mechanism 5 by a forklift, and the feeding mechanism 5 drives the glass wool boards 4 to move horizontally to a suitable position, and then the glass wool boards 4 are lifted at equal intervals each time according to their thickness, and the corresponding glass wool boards 4 are pushed onto the first conveyor belt 1 after each lifting, so that the automatic feeding of the glass wool boards 4 can be realized;

[0037] The negative pressure lifting mechanism 65 is used to make the film body 10 on the discharge roller 61 bypass the guide roller 62 and then be adsorbed and connected with the corresponding upper adsorption roller 63 and lower adsorption roller 64, so that the film body 10 remains in a tensioned state when it is not in contact with the glass wool board 4. When the glass wool board 4 passes between the upper adsorption roller 63 and the lower adsorption roller 64, the negative pressure lifting mechanism 65 can not only make the upper adsorption roller 63 adaptively lifted, but also cancel the adsorption state of the upper adsorption roller 63 and the lower adsorption roller 64 after it is lifted, so that the film body 10 can be synchronously attached to both sides of the glass wool board 4 when passing through it.

[0038] like Figure 1-Figure 2 As shown, the loading mechanism 5 includes a feeding rack 51, a first limiting rack 52, a second limiting rack 53, a feeding roller 54, a lifting member 55, a lifting mechanism 56, a connecting rack 57, a cylinder 58 and a horizontal push rod 59. The feeding rack 51 is connected to the frame 3, and a plurality of feeding rollers 54 are rotatably installed in the feeding rack 51. The lifting member 55 is arranged in the frame 3, and the lifting member 55 is connected to the frame 3 through the lifting mechanism 56. The cylinder 58 is connected to the frame 3 through the connecting rack 57. The horizontal push rod 59 corresponds to the position of the first conveyor belt 1, and the horizontal push rod 59 is connected to the output end of the cylinder 58. The first limiting rack 52 is installed on the side wall of the feeding rack 51, and the second limiting rack 53 is installed on the side wall of the frame 3 near one end.

[0039] It should be noted that a forklift is used to place the stacked glass wool boards 4 on the feeding rack 51 and one side of the boards is fitted with the first limiting rack 52. The stacked glass wool boards 4 can be transported into the frame 3 by the rotating feeding roller 54 until the glass wool boards 4 are fitted with the second limiting rack 53. The lifting mechanism 56 is used to make the lifting member 55 drive the stacked glass wool boards 4 to rise a suitable distance so that the top glass wool board 4 and the horizontal push rod 59 are in the same horizontal plane. Then, the cylinder 58 is started to drive the horizontal push rod 59 to move forward, so that the top glass wool board 4 can be pushed onto the first conveyor belt 1. Then, the lifting is continued so that the next glass wool board 4 corresponds to the horizontal push rod 59. This cycle is repeated, so that the glass wool boards 4 can be pushed onto the first conveyor belt 1 in sequence.

[0040] like Figure 1-Figure 2As shown, the lifting mechanism 56 includes a support plate 561, a stepper motor 562, a screw rod 563, a threaded sleeve 564 and a slider 565. The support plate 561 is installed on the side wall of the frame 3 near the top, the stepper motor 562 is installed on the top of the support plate 561, the screw rod 563 is coaxially connected to the output end of the stepper motor 562, the threaded sleeve 564 is sleeved on the screw rod 563, and the threaded sleeve 564 is connected to the lifting member 55, the slider 565 is installed on one side of the lifting member 55, and the slider 565 is slidably sleeved with the second limit frame 53.

[0041] It should be noted that the stepper motor 562 is started to control the number of revolutions of the screw rod 563 to control the rising stroke (this is the prior art and will not be elaborated here). The slider 565 cooperates with the second limit frame 53 to limit the rotational freedom of the lifting member 55. Therefore, when the screw rod 563 rotates, it can drive the threaded sleeve 564 and the lifting member 55 to rise and fall synchronously.

[0042] like Figure 1-Figure 2 As shown, the first conveyor belt 1 and the second conveyor belt 2 are respectively installed with a first support frame 11 and a second support frame 21, and the first support frame 11 and the second support frame 21 are respectively installed with a limit adjustment mechanism 7 for limiting the position of the glass wool board 4, and the first support frame 11 and the second support frame 21 are both installed with a driving mechanism 8 for driving the glass wool board 4 to feed.

[0043] It should be noted that the limit adjustment mechanism 7 can be used to make corresponding adjustments according to the width of the glass wool board 4, so that the glass wool board 4 is not prone to position displacement when being transported by the first conveyor belt 1 and the second conveyor belt 2, which is beneficial to improving the stability of transportation. The two driving mechanisms 8 respectively correspond to the end of the first conveyor belt 1 and the initial end of the second conveyor belt 2, so as to facilitate the transition of the glass wool board 4 from the first conveyor belt 1 to the second conveyor belt 2.

[0044] like Figure 3-Figure 4 As shown, the negative pressure lifting mechanism 65 includes a negative pressure shell 651, a cross bar 652, a negative pressure tube 653, a conduit 654, a solenoid valve 655 and a telescopic connecting piece 656. The two negative pressure shells 651 are located at the two ends of the lower adsorption roller 64. The first support frame 11 and the second support frame 21 are respectively connected to the negative pressure shells 651 through the cross bar 652. The negative pressure tube 653 is connected to one of the negative pressure shells 651. The solenoid valve 655 is installed on the other negative pressure shell 651. The negative pressure shell 651 is connected to the inner cavity of the lower adsorption roller 64 through the conduit 654. The negative pressure shell 651 is connected to the inner cavity of the upper adsorption roller 63 through the telescopic connecting piece 656.

[0045] It should be noted that the negative pressure tube 653 is connected to an external vacuum generator (not shown in the figure). Closing the solenoid valve 655 and starting the vacuum generator can put the negative pressure shell 651, the upper adsorption roller 63 and the lower adsorption roller 64 in a negative pressure state. The negative pressure adsorption principle can be used to make the film body 10 on the discharge roller 61 bypass the guide roller 62 and be adsorbed and connected with the upper adsorption roller 63 and the lower adsorption roller 64, so that the film body 10 remains in a tensioned state. When the glass wool board 4 is transported between the upper adsorption roller 63 and the lower adsorption roller 64, the telescopic connecting piece 656 is used to facilitate the adaptive lifting of the upper adsorption roller 63. After lifting, the adsorption state of the upper adsorption roller 63 and the lower adsorption roller 64 is cancelled, so that the glass wool board 4 can be simultaneously pasted on both sides when passing through.

[0046] like Figure 4-Figure 5 As shown, the telescopic connecting piece 656 includes an L-shaped tube 6561, a cylinder 6562, a piston 6563, a spring 6564 and a branch pipe 6565. The two ends of the L-shaped tube 6561 are respectively connected to the bottom of the cylinder 6562 and the end of the upper adsorption roller 63. The piston 6563 is adapted to the inner cavity of the cylinder 6562 and fixedly mounted on the outer tube wall of the L-shaped tube 6561 near the top. The spring 6564 is installed in the cylinder 6562, and the bottom end of the spring 6564 is connected to the piston 6563. The cylinder 6562 is connected to the negative pressure shell 651 through the branch pipe 6565.

[0047] It should be noted that the glass wool board 4 (such as Figure 2 When the upper adsorption roller 63 is lifted, the L-shaped tube 6561 can drive the piston 6563 to rise along the cylinder 6562, and compress the spring 6564 during the rising process. This arrangement not only allows the upper adsorption roller 63 to be adaptively lifted, but also facilitates the control of the negative pressure state of the upper adsorption roller 63. In this embodiment, a pressure sensor that contacts the top of the spring 6564 can be installed on the lower surface of the top of the cylinder 6562. When the upper adsorption roller 63 is lifted, it is detected that the pressure becomes larger, and the external controller is used to conveniently control the solenoid valve 655 to open and close the vacuum generator, thereby automatically canceling the upper adsorption roller 63 and the lower adsorption roller 64 (as shown in the figure). Figure 3 The negative pressure adsorption state (as shown) enables the membrane body 10 to move with the glass wool board 4 and adhere to both sides thereof.

[0048] like Figure 3 and Figure 6 As shown, the roller walls of the upper adsorption roller 63 and the lower adsorption roller 64 are respectively provided with adsorption holes 9 connected to their inner cavities, and the L-shaped tube 6561 and the conduit 654 are respectively connected to the upper adsorption roller 63 and the lower adsorption roller 64 coaxially for rotation.

[0049] It should be noted that a first sealed bearing is installed between the L-shaped tube 6561 and the upper adsorption roller 63, a second sealed bearing is installed between the conduit 654 and the lower adsorption roller 64, and the many adsorption holes 9 on the upper adsorption roller 63 and the lower adsorption roller 64 are equidistantly distributed along their length direction.

[0050] like Figure 2 and Figure 7 As shown, the limit adjustment mechanism 7 includes a U-shaped shell 71, a roller 72, an L-shaped member 74 with a through slot 73, a support rod 75, a bolt 76 and a nut 77. The U-shaped shell 71 is symmetrically distributed along the length direction of the first conveyor belt 1 and the second conveyor belt 2, respectively. A number of rollers 72 are rotatably installed in the U-shaped shell 71. The U-shaped shell 71 is connected to the L-shaped member 74 through the support rod 75. The bolts 76 are respectively arranged on the first support frame 11 and the second support frame 21, and the bolts 76 are arranged through the through slot 73, and the nuts 77 are installed on the bolts 76.

[0051] It should be noted that, according to the width of the glass wool board 4, the U-shaped shell 71 is pushed so that the roller 72 can contact the side of the glass wool board 4. During the movement of the U-shaped shell 71, the L-shaped part 74 and the bolt 76 will slide relative to each other under the action of the through groove 73. After adjusting the appropriate position, tighten the nut 77 to press the L-shaped part 74, so that the position of the U-shaped shell 71 can be locked.

[0052] like Figure 2 and Figure 8 As shown, the driving mechanism 8 includes an inverted U-shaped frame 81, a roller 82, a driving motor 83, a guide sleeve 84, a guide column 85, a top plate 86 and a screw 87. The two top plates 86 are respectively connected to the top of the first support frame 11 and the second support frame 21 through the guide column 85. The inverted U-shaped frame 81 is located below the top plate 86. The roller 82 is rotatably installed in the inverted U-shaped frame 81. The driving motor 83 is arranged at one end of the inverted U-shaped frame 81 and is used to drive the roller 82 to rotate. The inverted U-shaped frame 81 is slidably connected to the guide rod through the guide sleeve 84. The screw 87 passes through the top plate 86 and is rotatably connected to the top of the inverted U-shaped frame 81.

[0053] It should be noted that the rotating screw 87 is convenient for adjusting the lifting of the roller 82, so as to adapt to glass wool boards 4 of different thicknesses. The driving motor 83 is started to drive the roller 82 to rotate, so that when the roller 82 contacts the top of the glass wool board 4, a feeding driving force is applied to the glass wool board 4 to ensure that the glass wool board 4 can be moved between the upper adsorption roller 63 and the lower adsorption roller 64 (such as Figure 3 shown) passed smoothly.

[0054] A production method of a glass wool board automatic film laminating and packaging production equipment, using the above-mentioned glass wool board automatic film laminating and packaging production equipment, comprising the following steps:

[0055] Step 1: Use the loading mechanism 5 to horizontally convey the stacked glass wool boards 4, lift them at equal distances after they are transported to the right place, and push the stacked glass wool boards 4 onto the first conveyor belt 1 in sequence;

[0056] Step 2: Pull the film 10 on the upper discharge roller 61 to make it pass through the upper guide roller 62 and then be adsorbed and connected to the upper adsorption roller 63; pull the film 10 on the lower discharge roller 61 to make it pass through the lower guide roller 62 and then be adsorbed and connected to the lower adsorption roller 64;

[0057] Step 3: When the glass wool board 4 is transported between the upper adsorption roller 63 and the lower adsorption roller 64, the upper adsorption roller 63 is automatically lifted up by the negative pressure lifting mechanism 65, and after being lifted up, the upper adsorption roller 63 and the lower adsorption roller 64 are controlled to cancel the adsorption of the film body 10;

[0058] Step 4: When the glass wool board 4 passes between the upper adsorption roller 63 and the lower adsorption roller 64, the pressure applied by the upper adsorption roller 63 can be used to make the film body 10 on the upper discharge roller 61 and the lower discharge roller 61 respectively adhere to the top and bottom of the glass wool board 4. After the film is adhered, it is sent away by the second conveyor belt 2.

[0059] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
