Description

Technical Field

[0001] The invention belongs to the technical field related to corrugated paper production, and specifically relates to a thickness control device and a control method for corrugated paper production. Background Art

[0002] Corrugated paper boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products. Corrugated paper boxes are rigid paper containers made of corrugated cardboard through die-cutting, creasing, nailing or gluing. The height of corrugated cardboard under a certain pressure is called thickness, and the edge pressure strength will directly affect the supporting strength of the corrugated box. Therefore, the thickness of corrugated cardboard is a relatively important part of the production process.

[0003] At present, in the prior art, the gap distance between the upper roller and the lower roller can be adjusted arbitrarily by a large jack and a small jack, and the corrugated paper is fed into the gap from the gap to be pressed, so that the corrugated paper reaches a uniform thickness, and the thickness of the corrugated paper is more flexible. However, when the adjustment structure is used for adjustment, the rotation handles on both sides need to be rotated at the same time to complete the adjustment. This requires that the movement frequency of both sides of the equipment must always be kept the same during the adjustment process, which is inconvenient. Therefore, in order to solve the problem of inconvenient adjustment, a corrugated paper production thickness control device and control method are designed. Summary of the invention

[0008] By using the connecting rope and the winding roller in the adjustment component, the servo motor drives the winding roller to rotate, so that the connecting rope moves and contracts, so that the pressure roller at the lower end of the top frame can be adjusted and used at the same time, and due to the limitation of the sliding rod and the slider, the top frame can only be adjusted by vertical downward movement, thereby ensuring the smooth descent of the pressure roller and making the adjustment more convenient.

[0009] By sliding the slider and the limit block arranged on the side of the top frame close to the fixed frame in the slide groove and the through groove, and by setting the slide rod and the limit plate on the side of the top frame away from the fixed frame, the top frame can only descend vertically when it is pulled down by the connecting rope, thereby ensuring the stability of the pressure roller when it descends, and ensuring that the two ends of the pressure roller can descend synchronously.

An adjustment slot is provided in the fixed block, and a fixing component is installed in the adjusting slot. The fixing component includes a press block, one side of the press block is fixedly connected to a push rod, and the push rod is fixedly connected to a push plate away from the press block. One side of the lower end of the push plate is fixedly connected to a card block, and the card block is connected to the card slot.

[0013] Preferably, the top frame is fixedly connected to a limiting plate on one side away from the fixed frame, limiting frames are inserted into both sides of the upper end of the top frame, and the connecting rope passes through the limiting frames.

[0014] Preferably, the middle part of the limit plate is slidably connected to a slide rod, the lower end of the slide rod is fixedly connected to a support plate, a No. 1 spring is provided at the lower end of the limit plate, and the lower end of the No. 1 spring is fixedly connected to the support plate.

[0015] Preferably, the winding roller is composed of two fixed rollers, and the two fixed rollers are connected by an insertion rod.

[0016] Preferably, the front and rear parts of the winding roller are rotatably connected to the protection plate.

[0017] Preferably, one side of the two support plates is slidably connected to the protection rod, and the two support plates can fit together.

[0018] Preferably, a control method for the thickness control device of corrugated paper production based on the above-mentioned method comprises the following steps:

[0019] 1. Place the corrugated paper on the pressure roller on the bottom frame, start the servo motor in the adjustment assembly, reel and shrink the connecting rope, and drive the top frame to descend, so that the top frame drives the pressure roller to descend, so that the two pressure rollers are close to each other and press the corrugated paper;

[0020] 2. Observe the scale line and stop the top frame from descending when the thickness of the corrugated paper reaches the standard;

[0022] Compared with the existing scoring mechanism technology, the present invention provides a control method for a corrugated paper production thickness control device, which has the following beneficial effects:

[0023] First, the present invention uses the connecting rope and the winding roller in the adjustment component to make the servo motor drive the winding roller to rotate, so that the connecting rope moves and contracts, so that the pressure roller at the lower end of the top frame can be adjusted and used at the same time, and due to the limitation of the slide rod and the slider, the top frame can only be adjusted to descend vertically, thereby ensuring the smooth descent of the pressure roller, making the adjustment more convenient, and the adjustable spacing between the two support plates is conducive to adjusting and using according to the length of the corrugated paper, preventing the corrugated paper from tilting due to the equipment being too short when processing longer corrugated paper;

[0024] Second, the fixing block of the present invention adopts the method of clamping the fixing frame with the clamping block in the fixing assembly, which can facilitate the disassembly of the fixing block, thereby facilitating the disassembly and removal of the top frame, facilitating the inspection and replacement of the top frame, and facilitating the use of the equipment.

[0033] 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.

[0034] Embodiment 1

[0035] See also Figure 1-6 The present invention provides a technical solution: a corrugated paper production thickness control device and control method, comprising two support plates 1, one side of the upper end of the support plate 1 is fixedly connected to a fixed frame 2, a scale line is engraved on the surface of the front fixed frame 2, one side of the fixed frame 2 is slidably connected to a top frame 5, the middle part of the upper end of the support plate 1 is fixedly connected to a bottom frame 8, and pressure rollers 9 are installed on the bottom frame 8 and the top frame 5. In the adjustment structure used, in order to keep the two sides of the pressure roller 9 moving smoothly and no longer tilting during adjustment, the two sides are generally rotated separately and adjusted at the same time to ensure the level of the two sides. The separate adjustment method requires the two sides to keep consistent when rotating, which is difficult and not conducive to operation. Therefore, in order to effectively adjust the lifting and lowering of the pressure roller 9 and ensure the level of the two sides of the pressure roller 9, a protective groove is opened in the support plate 1, and an adjustment component 4 is installed in the protective groove.

[0036] The arranged adjustment component 4 comprises a servo motor 41, the output end of the servo motor 41 is fixedly connected to a winding roller 42, the front and rear parts of the winding roller 42 are both rotatably connected to a protective plate 421, the front and rear parts of the winding roller 42 are both fixedly wound with a connecting rope 43, the end of the connecting rope 43 away from the winding roller 42 passes through a protective groove and bypasses a fixed connecting ring 44 at the upper end of the top frame 5, and the end of the connecting rope 43 close to the winding roller 42 passes through the ring 44, and one side of the ring 44 is fixedly connected to the support plate 1.

[0037] In actual use, the servo motor 41 can be started, so that the servo motor 41 drives the winding roller 42 to rotate, and the winding roller 42 drives the two connecting ropes 43 to move. When the connecting rope 43 is pulled by the winding roller 42, the connecting rope 43 is tightened, and the limit frame 51 sliding with the connecting rope 43 is lowered, and the limit frame 51 drives the top frame 5 to descend, so that the pressure roller 9 in the top frame 5 is lowered. During the process of descending adjustment, observe the scale line. When the required value is reached, the rotation of the servo motor 41 can be stopped, and the connecting rope 43 can be fixed to adjust the distance between the two pressure rollers 9, so that the pressure roller 9 controls the thickness of the corrugated paper.

[0038] Furthermore, when the adjustment component 4 is used to drive the top frame 5 to move, in order to ensure that the connecting rope 43 stably drives the top frame 5 to move when it contracts, a limit plate 52 is fixedly connected to the side of the top frame 5 away from the fixed frame 2, and the limit frames 51 are inserted on both sides of the upper end of the top frame 5, and the connecting rope 43 passes through the limit frames 51, so that the limit frame 51 sliding with the connecting rope 43 is driven by the process of descending, so that the limit frame 51 drives the top frame 5 at the lower end to descend.

[0039] Furthermore, when the limit frame 51 is used to drive the top frame 5 to descend, in order to ensure that the top frame 5 descends vertically without tilting, a slide rod 11 is slidably connected to the middle of the limit plate 52, and the lower end of the slide rod 11 is fixedly connected to the support plate 1. A spring No. 10 is provided at the lower end of the limit plate 52, and the lower end of the spring No. 10 is fixedly connected to the support plate 1.

[0040] During the descending process, the limit plate 52 follows the top frame 5 to descend and squeezes the No. 1 spring 10 to contract. At the same time, the limit plate 52 is limited by the slide bar 11, so that the top frame 5 can only descend vertically.

[0041] Furthermore, when the adjustment component 4 is used to adjust the height of the top frame 5, in order to ensure further stable movement of the top frame 5, a through groove 21 is opened in the middle of the fixed frame 2, and slide grooves 22 are opened at the front and rear parts of the through groove 21. A slider 53 is slidably connected in the through groove 21, one side of the slider 53 is fixedly connected to the top frame 5, and the front and rear parts of the slider 53 are fixedly connected to a limit block 531, and the limit block 531 is slidably connected to the slide groove 22, so that the slider 53 and the limit block 531 slide in the slide groove 22 and the through groove 21 to limit the top frame 5, so that the top frame 5 can maintain a vertical descent when driving the pressure roller 9 to descend for adjustment.

[0042] In general, the slider 53 and the limit block 531 arranged on the side of the top frame 5 close to the fixed frame 2 slide in the slide groove 22 and the through groove 21, and the slide rod 11 and the limit plate 52 are arranged on the side of the top frame 5 away from the fixed frame 2, so that the top frame 5 can only descend vertically when it is pulled down by the connecting rope 43, thereby ensuring the stability of the pressure roller 9 when it descends, and ensuring that the two ends of the pressure roller 9 can descend synchronously.

[0043] By using the connecting rope 43 and the winding roller 42 in the adjustment component 4, the servo motor 41 drives the winding roller 42 to rotate, so that the connecting rope 43 moves and contracts, so that the pressure roller 9 at the lower end of the top frame 5 can be adjusted and used at the same time, and due to the limitation of the slide bar 11 and the slider 53, the top frame 5 can only be adjusted to descend vertically, thereby ensuring the smooth descent of the pressure roller 9 and making the adjustment more convenient.

[0044] Furthermore, the winding roller 42 used is composed of two fixed rollers, and the two fixed rollers are connected by an insertion rod 422, and one side of the two support plates 1 is slidably connected to the protection rod 3, and the two support plates 1 can fit together. When the length of the corrugated paper is long, in order to ensure that the pressing roller 9 can effectively control the thickness of the corrugated paper and ensure that the corrugated paper does not tilt and bend when passing through the pressing roller 9, the two ends of the winding roller 42 are arranged to be relatively slidable, so that the two support plates 1 can be adjusted, and the distance between the front and rear top frames 5 can be adjusted, which is convenient for thickness control of longer corrugated paper.

[0045] By setting the distance between the two support plates 1 to be adjustable, it is convenient to adjust the use according to the length of the corrugated paper, and prevent the corrugated paper from tilting due to the equipment being too short when processing longer corrugated paper.

[0046] Embodiment 2

[0047] See also Figure 1-6 , further improvements were made on the basis of Example 1:

[0048] Furthermore, when the top frame 5 and the pressure roller 9 on the top frame 5 need to be inspected and replaced, in order to ensure the convenience of inspection of the top frame 5 and the pressure roller 9, card slots 23 are opened on both sides of the upper end of the fixed frame 2, and the card slot 23 is clamped with the fixed block 6 through the fixed component 7. An adjustment slot is opened in the fixed block 6, and a fixing component 7 is installed in the adjusting slot. The fixing component 7 includes a pressing block 71, one side of the pressing block 71 is fixedly connected to a push rod 72, the side of the push rod 72 away from the pressing block 71 is fixedly connected to a push plate 73, and one side of the lower end of the push plate 73 is fixedly connected to a card block 74, and the card block 74 is clamped with the card slot 23.

[0049] Furthermore, when the fixing block 6 is used again, in order to ensure that the card block 74 can be moved out of the adjusting groove again so that the card block 74 can be engaged with the card groove 23 again, a No. 2 spring 75 is fixedly connected to the side of the push plate 73 away from the push rod 72, and the No. 2 spring 75 is fixedly connected to the inner wall of the adjusting groove. By using the No. 2 spring 75 to push the push plate 73 to move, the push plate 73 drives the card block 74 to move, so that the card block 74 can be engaged with the card groove 23 again.

[0050] By using the fixing block 6 to clamp the fixing frame 2, the fixing block 6 can be quickly removed from the fixing frame 2, so that it is easy to take out the slider 53 located at the lower end of the fixing block 6 and the fixing frame 2, thereby facilitating the disassembly of the top frame 5.

[0051] The specific disassembly process of the top frame 5 is as follows: when maintenance is needed, the two buttons 71 can be pressed to make the button blocks 71 drive the push rod 72 to move, and the push rod 72 drives the push plate 73 to move, and the push plate 73 drives the card block 74 to move, so that the card block 74 is separated from the card slot 23, and the card block 74 enters the adjustment slot, and then the fixed block 6 is separated from the fixed frame 2, and the slider 53 and the top frame 5 are removed, and then the limit frame 51 is separated from the top frame 5, so as to facilitate the replacement and maintenance of the top frame 5.

[0052] The working principle and use process of the present invention are as follows: when making adjustments, the servo motor 41 can be started, so that the servo motor 41 drives the winding roller 42 to rotate, so that the winding roller 42 drives the two connecting ropes 43 to move. When the connecting ropes 43 are pulled by the winding roller 42, the connecting ropes 43 are tightened, and the limit frame 51 sliding with the connecting ropes 43 is lowered, and the limit frame 51 drives the top frame 5 to lower, so that the pressure roller 9 in the top frame 5 is lowered. In the process of lowering, the limit plate 52 follows the top frame 5 to lower, and squeezes the No. 1 spring 10 to contract, and at the same time the limit plate 52 is limited by the slide bar 11, so that the top frame 5 can only descend vertically. During the descending adjustment process, observe the scale line. When the required value is reached, the rotation of the servo motor 41 can be stopped, and the connecting rope 43 can be fixed. Then the corrugated cardboard is passed through between the pressing rollers 9, so that the pressing rollers 9 squeeze the corrugated cardboard, thereby achieving the effect of thickness control. When the corrugated cardboard is long, the rear support plate 1 can also be pulled to separate the two support plates 1, so that the pressing rollers 9 can effectively squeeze the long corrugated cardboard to prevent the corrugated cardboard from bending.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
