Description

Technical Field

[0001] The utility model relates to the technical field of composite paper production, in particular to a pressing device for composite paper. Background Technique

[0002] Composite paper is a processed paper laminated by using adhesives to layer paper, cardboard and other materials (such as plastics, aluminum foils, cloth, etc.). This material not only improves the appearance performance and strength of paper and cardboard, but more importantly, improves its waterproof, moisture-proof, oil-resistant, airtight and fragrance-preserving properties. In addition, composite paper can also obtain characteristics such as heat-sealability, light-blocking property and heat-resistance. A pressing device is required during the processing of composite paper.

[0003] At present, when the existing pressing device presses composite paper, although it can press composite paper with different thicknesses, the adjustment of the pressing force is relatively troublesome. It is necessary to stop the work of the pressing device and then adjust the pressing force between the two conveyor belts. If the production models of composite paper are frequently changed, such adjustment of the pressing force is a waste of time and will delay the production efficiency of composite paper. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pressing device for composite paper to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pressing device for composite paper includes two parallel and fixed support platforms up and down. A conveying mechanism is arranged on the outer side of the support platform. Pressing mechanisms are arranged on one side surface of the two support platforms facing each other. The pressing mechanism includes a moving plate sliding between the two support platforms. Limiting plates are fixedly connected to both sides of the top surface of the moving plate. A plurality of cylindrical blocks are rotatably arranged at equal intervals between the two limiting plates at corresponding positions. A lifting plate is arranged between the moving plate and the support platform at the corresponding position. Sleeve barrels are fixedly connected to the four corners of the top surface of the lifting plate. A sleeve rod fixed to the moving plate at the corresponding position is sleeved inside the sleeve barrel. A second spring is fixed between the sleeve rod and the sleeve barrel at the corresponding position.

[0007] Furthermore: Four thread sleeves distributed in a rectangle are rotatably penetrated through the top surface of the support platform. A screw rod fixed to the lifting plate at the corresponding position is screwed inside the thread sleeve.

[0008] Furthermore, on both sides of the opposite side surfaces of the two support platforms, fixing plates are fixedly connected. On the outer wall of the threaded sleeve, a worm gear is fixedly connected. Between the two fixing plates at the same support platform, two symmetrical worms that mesh with the worm gears at the corresponding positions are rotatably connected. One end of the worm penetrates through the side surface of the fixing plate at the corresponding position and is fixedly connected with a belt pulley. Between the two belt pulleys at the relative positions, transmission is carried out through a belt. One end of one of the worms at the same support platform is fixedly connected with a rotating block.

[0009] Furthermore, at both ends of both sides of the bottom surface and the top surface of the support platform, fixing blocks are fixedly connected. Between the two fixing blocks at the relative positions, an auxiliary roller is rotatably connected. The conveying mechanism includes two symmetrical connecting plates. Between the two connecting plates at the relative positions, three circular rollers are rotatably arranged at equal intervals. A conveyor belt rolls between the six circular rollers and the four auxiliary rollers at the same support platform.

[0010] Furthermore, a connecting block is fixedly connected to one side surface of the connecting plate. On both sides of the end surface of the support platform, rectangular sleeves inserted with the connecting blocks at the corresponding positions are fixedly connected. A first spring is fixed between the connecting block and the rectangular sleeve at the corresponding position.

[0011] Furthermore, in the middle of one side surface of one of the connecting plates at the same support platform, a cushion plate is fixedly connected. On the top surface of the cushion plate, a motor is fixedly connected. The output end of the motor penetrates through the connecting plate at the corresponding position and is fixed to the circular roller at the corresponding position.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By adjusting the distance between the two lifting plates, the compression degree of the second spring can be adjusted. Therefore, the pressing force on the composite paper can be adjusted according to the requirements of composite paper production, and during the adjustment process, there is no need to stop the machine, thereby improving the efficiency of composite paper pressing, and the device is simple and convenient to operate.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a pressing device for composite paper includes two parallel and fixed support platforms 1 up and down. A conveying mechanism 2 is arranged on the outer side of the support platform 1. Pressing mechanisms 3 are arranged on the opposite side surfaces of the two support platforms 1. The pressing mechanism 3 includes a moving plate 31 that slides between the two support platforms 1. Limiting plates 32 are fixedly connected to both sides of the top surface of the moving plate 31. A plurality of cylindrical blocks 33 are rotatably arranged at equal intervals between the two limiting plates 32 at corresponding positions. A lifting plate 34 is arranged between the moving plate 31 and the support platform 1 at the corresponding position. Sleeve rods fixed to the moving plate 31 at the corresponding position are sleeved inside sleeves 35 fixedly connected to the four corners of the top surface of the lifting plate 34. A second spring is fixed between the sleeve rod and the sleeve 35 at the corresponding position.

[0021] Specifically, first, the composite paper after production is placed between two conveying mechanisms 2, and the composite paper is moved by the two conveying mechanisms 2. When the composite paper moves between the two moving plates 31, the second spring will be compressed because the composite paper has a certain thickness. Since the force is mutual, the multiple cylindrical blocks 33 will extrude the composite paper under the action of the four second springs at the corresponding positions, making the composite paper more compact. When the composite paper moves out from between the two conveying mechanisms 2, the staff can observe the pressing condition of the composite paper. If the pressed composite paper does not meet the requirements, at this time, the two lifting plates 34 can be moved closer to each other, so that the sleeve rod is retracted into the sleeve 35 at the corresponding position and the second spring is compressed. Then, the composite paper is placed between the two conveying mechanisms 2 again. When the composite paper moves between the two moving plates 31, the second spring can be compressed again. Due to the characteristics of the second spring, the more the second spring is compressed, the greater the acting force applied to the two moving plates 31. Then, the staff observes the pressing condition of the composite paper again. If it still does not meet the requirements, continue to move the two lifting plates 34 closer until the pressing degree of the composite paper meets the requirements. This device can adjust the compression degree of the second spring by adjusting the distance between the two lifting plates 34. Therefore, the pressing force on the composite paper can be adjusted according to the production requirements of the composite paper, and the device does not need to stop during the adjustment process, thus improving the pressing efficiency of the composite paper, and the device is simple and convenient to operate.

[0022] Embodiment 1

[0023] As Figure 4 shown, in this embodiment, four thread sleeves 36 distributed in a rectangle penetrate and rotate on the top surface of the support platform 1. A screw rod 361 fixed to the lifting plate 34 at the corresponding position is screwed and connected inside the thread sleeve 36. Both sides of the opposite side surfaces of the two support platforms 1 are fixedly connected with fixing plates 11. A worm gear 37 is fixedly connected to the outer wall of the thread sleeve 36. Two symmetrical worm shafts 38 meshing with the corresponding worm gears 37 are rotatably connected between the two fixing plates 11 at the same support platform 1. One end of the worm shaft 38 penetrates the side surface of the corresponding fixing plate 11 and is fixedly connected with a belt pulley 381. The two belt pulleys 381 at the relative positions are driven by a belt. One end of one of the worm shafts 38 at the same support platform 1 is fixedly connected with a rotating block 382.

[0024] In this embodiment, by rotating the rotating block 382, the two corresponding worm shafts 38 can be rotated. The rotating worm shaft 38 can make the corresponding worm gear 37 drive the corresponding thread sleeve 36 to rotate. Since the thread sleeve 36 is screwed with the screw rod 361 at the corresponding position, the rotating thread sleeve 36 can make the screw rod 361 move, and the moving screw rod 361 can drive the lifting plate 34 at the corresponding position to move, so that the compression degree of the four second springs at the corresponding positions can be adjusted.

[0025] Embodiment 1

[0026] As Figure 1 and Figure 3 shown, in this embodiment, fixed blocks 12 are fixedly connected to both ends on both sides of the bottom surface and the top surface of the support table 1. An auxiliary roller 13 is rotatably connected between two fixed blocks 12 at corresponding positions. The conveying mechanism 2 includes two symmetric connecting plates 21. Three round rollers 24 are rotatably arranged at equal intervals between two connecting plates 21 at corresponding positions. A conveyor belt rolls between the six round rollers 24 and the four auxiliary rollers 13 located at the same support table 1. A connecting block 22 is fixedly connected to one side surface of the connecting plate 21. Rectangular sleeves 23 inserted with the connecting blocks 22 at corresponding positions are fixedly connected to both sides of the end surface of the support table 1. A first spring 25 is fixed between the connecting block 22 and the rectangular sleeve 23 at the corresponding position. A cushion plate 26 is fixedly connected to the middle of the side surface of one of the connecting plates 21 at the same support table 1. A motor 27 is fixedly connected to the top surface of the cushion plate 26. The output end of the motor 27 penetrates through the connecting plate 21 at the corresponding position and is fixed to the round roller 24 at the corresponding position.

[0027] In this embodiment, the rotation of the round roller 24 at the corresponding position can be driven by the motor 27. Since a conveyor belt rolls between the six round rollers 24 and the four auxiliary rollers 13 located at the same support table 1, the rotating round roller 24 can make the conveyor belt roll outside the support table 1 at the corresponding position, so that the composite paper between the two conveyor belts can move. Since the length of the conveyor belt is fixed, when the two lifting plates 34 approach each other, a part of the side surface where the two conveyor belts approach each other will bulge, so it will pull the conveyor belt, causing the connecting block 22 to move into the rectangular sleeve 23 at the corresponding position and compress the first spring 25, enabling the conveyor belt to drive the composite paper to move normally.

[0028] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
