Description

Technical Field

[0001] The invention relates to a corrugating machine, in particular to a multifunctional corrugating machine for producing flute tip to flute tip paperboard. Background Art

[0002] like Figure 1 As shown, the current corrugator for producing double-layer corrugated paper is provided with a face paper input end, a core paper input end and a double-layer corrugated paper output end; wherein, the core paper 001 is fed in from the core paper input end and processed into a corrugated shape by the corrugating roller 3, and at the same time, the face paper 101 is fed in from the face paper input end and is pressed together with the processed core paper by the pressing mechanism 5, so that the corrugated top of the core paper is bonded to the face paper to form a double-layer corrugated paper 002, as shown in FIG. Figure 8 The double-layer corrugated paper is shown in the figure. This double-layer corrugated machine uses corrugated rollers as driving power to drive the core paper to move. Under the pressure of the bonding and pressing mechanism, the core paper drives the bonding and pressing mechanism to move through the surface paper; therefore, this corrugated machine can only process a single layer of core paper and bond it with the surface paper, but it is difficult to process two layers of core paper and bond them with the surface paper to form a corrugated paper with two layers of core paper 003, as shown in FIG. Fig. 9 What is shown is corrugated paper with two layers of core paper; the reason is that the movement of the adhesive pressing mechanism between the two layers of core paper is driven by the surface paper, which will cause the two layers of core paper to be stretched and misaligned in the length direction, which may easily lead to problems such as misalignment between the core paper and the surface paper and damage to the two layers of core paper.

[0032] 2. The two layers of core paper of the present invention are initially bonded together between the bonding and pressing mechanism and the corrugated roller, and then pressed by the belt pressing mechanism and the traction belt of the bonding and pressing mechanism, so that the two layers of core paper are in contact and pressed with the surface paper for a longer time, thereby ensuring that the two layers of core paper can be more firmly bonded with the surface paper.

[0044] 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.

[0045] Example 1

[0046] Reference Figures 2 to 7 ,as well as Fig. 9The present embodiment relates to a multifunctional corrugating machine for producing flute-to-flute paperboard, including a corrugating roller 3 for processing a first core paper 1 and a second core paper 2 into a corrugated shape, a gluing mechanism 4 for brushing glue on the first core paper 1 and the second core paper 2, and a gluing mechanism 5 for gluing and pressing the two layers of core paper and a face paper 101 together; the first core paper 1 and the second core paper 2 are processed by the gluing mechanism 4 and the corrugating roller 3 to form a two-layer core paper 100 with flute tip against flute tip; the gluing mechanism 5 is provided with a power device 6, and the power device 6 drives the gluing mechanism 5 to rotate synchronously with the corrugating roller 3, so that the two layers of core paper 100 located between the gluing mechanism 5 and the corrugating roller 3 and the face paper 101 move synchronously and are gluing and pressing together.

[0047] During operation, the corrugating roller 3 and the gluing mechanism 4 process the input first core paper 1 and the second core paper 2 into corrugations and apply glue, and then the corrugated first core paper 1 and the second core paper 2 are correspondingly bonded together to form an integrated structure of two layers of core paper 100 with the corrugated tips facing each other. The present invention provides power to the gluing and pressing mechanism 5 by providing a power device 6, so that the gluing and pressing mechanism 5 drives the surface paper 101 to move, and at the same time, the corrugating roller 3 drives the two layers of core paper 100 with the corrugated tips facing each other to move. Since the present invention adopts the technical solution of synchronous movement of the sticking and pressing mechanism 5 and the corrugating roller 3, the corrugating roller 3 drives the two-layer core paper 100 and the surface paper 101 with the corrugation tips facing each other to contact and maintain synchronous movement, so that the two-layer core paper 100 and the surface paper 101 remain in a relatively static state to improve the accuracy of alignment, and ensure that there will be no mutual misalignment and stretching in the length direction between the two layers of core paper 100, thereby preventing the two layers of core paper 100 from being damaged. This solves the problem that when the existing double-layer corrugated paper corrugating machine produces corrugated paper with two layers of core paper 100, the two layers of core paper 100 are easily stretched and dislocated in the length direction, which leads to inaccurate alignment between the core paper and the surface paper 101 and damage to the two layers of core paper 100.

[0048] The gluing and pressing machine of the present invention has the same movement speed as the corrugating roller 3, and the movement speed of the two-layer core paper 100 and the face paper 101 is equal, so that the two-layer core paper 100 and the face paper 101 remain in a relatively static state. During processing, the two-layer core paper 100 and the face paper 101 move at the same speed along the length direction under the drive of the corrugating roller 3 and the gluing and pressing mechanism 5, respectively. At the same time, the gluing and pressing mechanism 5 applies pressure to the face paper 101 in the direction of the two-layer core paper 100, so that the face paper 101 and the two-layer core paper 100 are pressed against each other and bonded together, which not only ensures that the face paper 101 and the two-layer core paper 100 can be accurately aligned, but also ensures that the two-layer core paper 100 will not have the problem of misalignment and stretching, which greatly improves the product quality and stability of corrugated paper with two-layer core paper 100, thereby improving production efficiency and reducing production costs.

[0049] The bonding and pressing mechanism 5 includes a first active roller 51, a first driven roller 52, a traction belt 53 and the power device 6. The power device 6 includes a first motor 54. The traction belt 53 is wound around the first active roller 51 and the first driven roller 52. The power output end of the first motor 54 is connected to the first active roller 51 to drive the traction belt 53 to move. The traction belt 53 is close to the corrugated roller 3, and the traction belt 53 drives the face paper 101 to move, and the corrugated roller 3 drives the two-layer core paper 100 to move, so that the two-layer core paper 100 and the face paper 101 move at the same speed. The two-layer core paper 100 processed by the corrugated roller 3 to form a flute tip against a flute tip moves along the length direction driven by the traction belt 53, and at the same time, the traction belt 53 applies pressure to the face paper 101 in the direction of the two-layer core paper 100, so that the face paper 101 and the two-layer core paper 100 are pressed against each other and bonded together. The driving of the facing paper 101 by the traction belt 53 and the driving of the two layers of core paper 100 by the corrugated roller 3 moving synchronously with the traction belt 53 prevent the two layers of core paper 100 from being misaligned and stretched. The first motor 54 drives the first active roller 51 to rotate, and then drives the first driven roller 52 to rotate through the traction belt 53. By controlling the rotation speed of the first motor 54, the movement speed of the traction belt 53 is equal to the movement speed of the corrugated roller 3. Among them, the first active roller 51 is set to one, and the first driven roller 52 can be set to a plurality of first driven rollers as needed, and the positions of the plurality of driven rollers can be adaptively set and adjusted.

[0050] The output end of the corrugated roller 3 is provided with a belt pressing mechanism 7 for bonding the two layers of core paper 100 and the face paper 101. The belt pressing mechanism 7 moves synchronously with the traction belt 53. The two layers of core paper 100 and the face paper 101 bonded together output from between the bonding and pressing mechanism 5 and the corrugated roller 3 enter between the belt pressing mechanism 7 and the traction belt 53. The belt pressing mechanism 7 drives the two layers of core paper 100, and the traction belt 53 drives the face paper 101, so that the two layers of core paper 100 and the face paper 101 move at the same speed. The two layers of core paper 100 are initially bonded together between the bonding and pressing mechanism 5 and the corrugated roller 3, and then the two layers of core paper 100 are pressed together by the belt pressing mechanism 7 and the traction belt 53 of the bonding and pressing mechanism 5, so that the two layers of core paper 100 have a longer time to contact and press with the face paper 101, thereby ensuring that the two layers of core paper 100 can be more firmly bonded with the face paper 101. The movement speeds of the gluing and pressing mechanism 5, the corrugating roller 3 and the belt pressing mechanism 7 of the present structure are equal, and the gluing and pressing mechanism 5 and the corrugating roller 3 form a first group of synchronous motion mechanisms for gluing and pressing the two layers of core paper 100 and the face paper 101 together, while the gluing and pressing mechanism 5 and the belt pressing mechanism 7 form a second group of synchronous motion mechanisms, so that the entire gluing process of the two layers of core paper 100 and the face paper 101 is in a synchronous motion state, and there will be no relative movement and misalignment between the two layers of core paper 100 and the face paper 101, which ensures that the face paper 101 and the two layers of core paper 100 can be accurately aligned, and that the two layers of core paper 100 will not be damaged by misalignment and stretching. It can be seen that a set of synchronous motion devices is formed between the gluing and pressing mechanism 5, the corrugating roller 3 and the belt pressing mechanism 7 of the present invention, which can greatly improve the product quality and stability of the corrugated paper with two layers of core paper 100, reduce material loss, ensure the production efficiency and reduce production costs.

[0051] The belt pressing mechanism 7 includes a second active roller 71, a second driven roller 72, a belt pressing 73 and a second motor 74. The belt pressing 73 is sleeved on the second active roller 71 and the second driven roller 72. The power output end of the second motor 74 is connected to the second active roller 71 to drive the belt pressing 73 to move. The belt pressing 73 is close to the traction belt 53, and the belt pressing 73 drives the two layers of core paper 100, and the traction belt 53 drives the surface paper 101, so that the two layers of core paper 100 and the surface paper 101 move at the same speed. The movement speed of the belt pressing 73 along the length direction is equal to the movement speed of the traction belt 53 along the length direction, so that the two layers of core paper 100 are initially bonded together between the traction belt 53 and the corrugated roller 3, and then the two layers of core paper 100 are pressed by the belt pressing 73 and the traction belt 53, so that the two layers of core paper 100 have a longer time to contact and press with the surface paper 101, thereby ensuring that the two layers of core paper 100 can be more firmly bonded with the surface paper 101. The movement speeds of the corrugating roller 3, the traction belt 53 and the pressing belt 73 are equal, so that during the entire processing process, the two layers of core paper 100 and the surface paper 101 always remain in a relatively static state during the two bonding and pressing processes, thereby allowing the two layers of core paper 100 to maintain contact and pressure with the surface paper 101 in an accurate position for a long time, achieving a stable bonding state.

[0052] The sticking and pressing mechanism 5 also includes a first pressure adjusting mechanism 55 for adjusting the pressure applied by the traction belt 53 to the facing paper 101. The first pressure adjusting mechanism 55 includes a first tension roller 56 and a first cylinder 57. The piston rod of the first cylinder 57 is movably connected to the first tension roller 56. The first tension roller 56 presses the end of the traction belt 53 away from the corrugating roller 3 to adjust the pressure of the end of the traction belt 53 close to the corrugating roller 3 and the belt pressing mechanism 7. Figure 2 As shown, when the piston rod of the first cylinder 57 extends to press the first tension roller 56, one end of the traction belt 53 close to the corrugated roller 3 will extend outward, thereby increasing the pressure applied to the facing paper 101, increasing the pressure between the facing paper 101 and the two layers of core paper 100, and improving the compression between the two. This structure can adjust the pressure of the traction belt 53 on the facing paper 101 by driving the first tension roller 56 by the first cylinder 57 according to the different compressions required between the core paper and the facing paper 101 of different thicknesses, so as to achieve corresponding adjustment of the compression, and has the advantages of simple structure, convenient adjustment and wide range.

[0053] The belt pressing mechanism 7 further includes a second pressure regulating mechanism 75 for regulating the pressure applied by the belt pressing mechanism 73 to the two layers of core paper 100. The second pressure regulating mechanism 75 includes a second tension roller 76 and a second cylinder 77. The piston rod of the second cylinder 77 is movably connected to the second tension roller 76. The second tension roller 76 presses the end of the belt pressing mechanism 5 away from the gluing and pressing mechanism 5 to regulate the pressure of the end of the belt pressing mechanism 73 close to the gluing and pressing mechanism 5. Figure 2As shown, when the piston rod of the second cylinder 77 extends to press the second tension roller 76, one end of the pressing belt 73 close to the traction belt 53 will extend outward, thereby increasing the pressure applied to the two layers of core paper 100, increasing the pressure between the two layers of core paper 100 and the surface paper 101, and improving the compression between the two. This structure can adjust the pressure of the pressing belt 73 on the two layers of core paper 100 by driving the second tension roller 76 by the second cylinder 77 according to the different compression required between the core paper and the surface paper 101 of different thicknesses, so as to achieve the corresponding adjustment of the compression, and has the advantages of simple structure, convenient adjustment and wide range.

[0054] A heating plate 8 corresponding to the position of the belt pressing mechanism 7 is provided on the inner side of the traction belt 53; the heating plate 8 contacts the traction belt 53 to heat and support the traction belt 53. The heating plate 8 supports the traction belt 53 moved to this position, so that the two layers of core paper 100 and the surface paper 101 can be bonded together for a longer time during the process of the pressing belt 73 and the traction belt 53 pressing and bonding the two layers of core paper 100 and the surface paper 101, thereby improving the stability and effect of bonding.

[0055] In addition, the heating plate 8 at this position directly heats the traction belt 53, so that the portion of the traction belt 53 passing through the heating plate 8 is directly heated to the required temperature, so as to be suitable for the two layers of core paper 100 and the face paper 101 located between the traction belt 53 and the pressure belt 73 to have a more suitable bonding temperature, so as to improve the bonding speed and efficiency, and achieve higher bonding stability and quality in a shorter time. The heating plate 8 can be in an arc shape; of course, it can also be set to a straight line shape according to the shape of the traction belt. When the pressure belt 73 applies pressure to the two layers of core paper 100 in the direction of the traction belt 53, the heating plate 8 can support the face paper 101, so that the two layers of core paper 100 can be stably adhered to the face paper 101; and the heating plate 8 can heat the traction belt, so that the glue between the face paper 101 and the two layers of core paper 100 can be solidified more quickly, so as to achieve the purpose and effect of quickly bonding the two together.

Fig. 9As shown in the figure, the corrugated paper with two layers of core paper can be processed and produced by stopping the first corrugated roller of the first embodiment and letting the second corrugated roller work alone. Similarly, when only the second corrugated roller is used for processing, the gluing and pressing mechanism and the second corrugated roller adopt synchronous motion, and the gluing and pressing mechanism and the second corrugated roller have the same motion speed, so that the two layers of core paper 100 and the surface paper 101 can be kept in a relatively static state to improve the accuracy of alignment, and it has the advantages of diversified functions, strong versatility and easy use.

[0063] Similar to Example 1, the movement speeds of the gluing and pressing mechanism 5, the corrugated roller 3 and the belt pressing mechanism 7 of this embodiment are equal, and the gluing and pressing mechanism 5 and the corrugated roller 3 form a first group of synchronous motion mechanisms for gluing the core paper 100 and the surface paper 101 together, while the gluing and pressing mechanism 5 and the belt pressing mechanism 7 form a second group of synchronous motion mechanisms, so that the core paper 100 and the surface paper 101 are in a state of synchronous motion throughout the entire gluing process, ensuring that the surface paper 101 and the two layers of core paper 100 can be more accurately aligned during the entire processing process.

[0064] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
