Abstract
Description
Technical Field
[0001] This utility model relates to the field of impregnated paper technology, and in particular to an impregnated paper alignment device. Background Technology
[0002] Impregnated paper is made from a mixture of non-woven wood pulp, PE, and plant fibers. It has super absorbency and resistance to dissolution. It is also a very economical low-particle-leaking paper towel. It is widely used in cabinets, wardrobes, and laminate flooring. The paper used for the veneer is impregnated with melamine glue and some additives to become melamine impregnated paper. It is then hot-pressed with the board and steel plate in a hot press to become the veneer.
[0003] In the processing and production of impregnated paper, alignment mechanisms are frequently used. For example, in the cutting device, the impregnated paper needs to be aligned to minimize cutting errors, and in the gluing device, it needs to be aligned to minimize uneven gluing at the edges. However, existing alignment mechanisms have the following problems:
[0004] 1. Most existing alignment devices are located inside other devices (such as cutting devices, gluing devices, etc.). Therefore, in the production process of impregnated paper, an alignment mechanism needs to be installed in each device. When the alignment mechanism wears out after long-term use, the operation of the device needs to be stopped for overall maintenance, which will affect the production efficiency of the device.
[0005] 2. After the impregnated paper shifts, some devices use limiting components to clamp and move the impregnated paper to adjust its deviation. Other devices use guiding components to adjust the impregnated paper. However, in actual operation, the limiting components need to stop the impregnated paper from being conveyed before the paper can be adjusted. If the impregnated paper is only guided by the guiding components, it will rub against the guiding components when the paper shifts significantly, thus damaging the paper and affecting the quality of the finished product. Utility Model Content
[0006] To address the aforementioned problems, the present invention aims to provide an impregnated paper alignment device that reduces wear on the impregnated paper while enabling alignment without the need for a stop device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An impregnated paper alignment device, covering the outside of an apparatus, includes a mounting plate covering the top of the apparatus, a pair of limiting components slidably disposed on the left and right sides of the lower surface of the mounting plate and sandwiched between the left and right sides of the apparatus, a pair of alignment components respectively disposed on opposite sides of the two limiting components, and an indicator component disposed between the two alignment components and extending above the mounting plate after passing through the mounting plate at its upper part; each alignment component includes a U-shaped mounting frame fixed to the inner side of the limiting component and extending in the front-rear direction, a push plate slidably disposed laterally within the U-shaped mounting frame, and a space between the U-shaped mounting frame and the push plate. The first reset spring and the arc-shaped guide plate fixed to the front end of the push plate; each set of limiting components includes a second slide rail laterally embedded on one side of the lower surface of the mounting plate, a limiting plate whose upper part is slidably connected to the second slide rail and whose lower part abuts against the outer side of the device on the corresponding side, a linear actuator fixed to the inner side of the limiting plate and abutting against the upper surface of the device, a plug fixed to the driving end of the linear actuator, and a control sub-assembly for controlling the locking or unlocking between the limiting plate and the second slide rail; the plug in each set of limiting components is inserted into the U-shaped mounting frame in the corresponding side adjustment assembly.
[0009] More preferably, the control sub-assembly includes a plurality of first limiting holes spaced apart on the upper surface of the second slide rail along the extension direction of the second slide rail, a plurality of second limiting holes spaced apart on the mounting plate and communicating with the corresponding first limiting holes, and a plug rod that passes through the second limiting holes and the first limiting holes in sequence at the bottom and is inserted into the limiting plate.
[0010] More preferably, the indicating component includes a first slide rail horizontally embedded in the middle of the lower surface of the mounting plate, a slider slidably disposed in the middle of the first slide rail, a pair of connecting rods symmetrically disposed on the left and right sides of the slider and whose upper parts are slidably connected to the first slide rail and whose lower parts are fixedly connected to the corresponding U-shaped mounting frames, a pair of second return springs respectively disposed on both sides of the slider and located between the slider and the connecting rods, and an indicating rod vertically fixed to the top of the slider and whose upper part passes through the first slide rail and the mounting plate in sequence and extends to the top of the mounting plate; a first channel that allows the indicating rod to pass through is provided through the first slide rail, a second channel communicating with the first channel is provided through the mounting plate, and the upper part of the indicating rod passes through the first channel and the second channel in sequence and extends to the top of the mounting plate.
[0011] More preferably, a first anti-wear layer is provided on one side of each of the two push plates, and a second anti-wear layer is fixed on one side of each of the two arc-shaped guide plates.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, the impregnated paper is placed in two U-shaped mounting frames on both sides, and the sides abut against the push plates on the corresponding sides. When the impregnated paper has a slight deviation, the first reset spring in the adjustment component on the offset side is squeezed and will push the push plate to move the impregnated paper in the opposite direction under the action of elastic force, thereby realizing the automatic adjustment of the impregnated paper. However, when the impregnated paper has a large deviation, the elastic force of the first reset spring alone cannot realize the adjustment of the impregnated paper. At this time, the linear driver on the offset side is activated. The extension of the driving end of the linear driver drives the insert block, U-shaped mounting frame and push plate to move in the opposite direction, thereby realizing the adjustment of the impregnated paper. Through the cooperation of the limiting component and the adjustment component, the friction between the impregnated paper and the guide component is avoided as much as possible without stopping the impregnated paper conveying, thereby improving the production efficiency of impregnated paper and reducing the impact on the quality of the finished impregnated paper.
[0014] 2. In this utility model, the device is mounted above other devices (such as cutting devices or gluing devices) by the cooperation of the limiting plates on both sides and the linear actuators on the corresponding sides. When not in use, the device can be lifted upwards to separate the alignment device from other devices. When the alignment device wears out after long-term use, there is no need to stop the operation of the production device, which can improve the production efficiency of the device.

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] An impregnated paper alignment device, covering the outside of a device, includes a mounting plate 1 covering the top of the device, a pair of limiting components 2 slidably disposed on the left and right sides of the lower surface of the mounting plate 1 and sandwiched between the left and right sides of the device, a pair of alignment components 3 respectively disposed on opposite sides of the two limiting components 2, and an indicator component 4 disposed between the two alignment components 3 and extending above the mounting plate 1 after passing through the mounting plate 1. Each alignment component 3 includes a U-shaped mounting frame 31 fixed to the inner side of the limiting component 2 and extending in the front-rear direction, a push plate 32 slidably disposed in the U-shaped mounting frame 31, and a first return spring 3 disposed between the U-shaped mounting frame 31 and the push plate 32. 3 and an arc-shaped guide plate 34 fixed to the front end of the push plate 32; each set of limiting components 2 includes a second slide rail 21 horizontally embedded on one side of the lower surface of the mounting plate 1, a limiting plate 22 whose upper part is slidably connected to the second slide rail 21 and whose lower part abuts against the outer side of the device on the corresponding side, a linear actuator 23 fixed to the inner side of the limiting plate 22 and abutting against the upper surface of the device, a plug 24 fixed to the driving end of the linear actuator 23, and a control sub-component 25 for controlling the locking or unlocking between the limiting plate 22 and the second slide rail 21; the plug 24 in each set of limiting components 2 is inserted into the U-shaped mounting frame 31 in the corresponding side adjustment component 3.
[0024] In this device, the impregnated paper is placed in two U-shaped mounting frames 31 on both sides, with its sides abutting against the push plates 32 on the corresponding sides. When the impregnated paper deviates slightly, the first return spring 33 in the offset component 3 on the offset side is compressed and, under the action of elastic force, pushes the push plate 32 to push the impregnated paper to move in the opposite direction, thereby realizing automatic offset adjustment of the impregnated paper. However, when the impregnated paper deviates significantly, the elastic force of the first return spring 33 alone cannot achieve offset adjustment of the impregnated paper. At this time, the linear actuator 23 on the offset side is activated, and the extension of the driving end of the linear actuator 23 drives the insert block 24, the U-shaped mounting frame 31, and the push plate 32 to move in the opposite direction. This allows for the alignment of the impregnated paper. The cooperation of the limiting component 2 and the alignment component 3 minimizes friction between the impregnated paper and the guide components without stopping the paper conveying process, thereby improving the production efficiency of the impregnated paper while reducing the impact on the quality of the finished product. In this device, the cooperation of the limiting plates 22 on both sides and the linear actuator 23 on the corresponding side allows the device to be mounted above other devices (such as cutting devices or gluing devices). When not in use, the device can be lifted upwards to separate the alignment device from other devices. Even when the alignment device wears out after long-term use, the production process can be continued without stopping the operation of the production device, thus improving the production efficiency of the device.
[0025] As a possible implementation of this solution, preferably, the control sub-assembly 25 includes a plurality of first limiting holes 211 spaced apart on the upper surface of the second slide rail 21 along the extension direction of the second slide rail 21, a plurality of second limiting holes 12 spaced apart on the mounting plate 1 and communicating with the corresponding first limiting holes 211, and a plug rod 251 that passes through the second limiting holes 12 and the first limiting holes 211 in sequence at the bottom and is inserted into the limiting plate 22. By inserting the plug rod 251 through the corresponding second limiting holes 12 and the first limiting holes 11 and into the limiting plate 22 on the corresponding side, the limiting plate 22 can be limited, and the left and right movement of the limiting plate 22 can be avoided as much as possible. This avoids the situation where the limiting plates 22 on both sides move when the device is mounted on other devices, causing the device to fall downward, thereby improving the safety of the device.
[0026] As a possible implementation of this solution, preferably, the indicating component 4 includes a first slide rail 41 horizontally embedded in the middle of the lower surface of the mounting plate 1, a slider 42 slidably disposed in the middle of the first slide rail 41, a pair of connecting rods 43 symmetrically disposed on the left and right sides of the slider 42 with their upper parts slidably connected to the first slide rail 41 and their lower parts fixedly connected to the corresponding side of the U-shaped mounting frame 31, a pair of second return springs 44 respectively disposed on both sides of the slider 42 and located between the slider 42 and the connecting rods 43, and a vertically fixed component on the top of the slider 42 with its upper part passing through the first slide rail 41 and the mounting plate 1 and extending to the mounting plate. The indicator rod 45 is located above the first slide rail 41. A first channel 411 is provided through the first slide rail 41 to allow the indicator rod 45 to pass through. A second channel 11 is provided through the mounting plate 1 to communicate with the first channel 411. The upper part of the indicator rod 45 passes through the first channel 411 and the second channel 11 in sequence and extends to the top of the mounting plate 1. The offset of the impregnated paper can be judged by the indication of the indicator rod 45. When the indicator rod 45 is offset, that is, the impregnated paper is offset for a long time, the extension of the driving end of the linear actuator 23 on both sides is adjusted to reduce the wear of the impregnated paper.
[0027] As a possible implementation of this solution, preferably, the push plate 32 is covered with a first anti-wear layer 321 on one side, and the two arc-shaped guide plates 34 are fixed with a second anti-wear layer 341 on one side; by setting the first anti-wear layer 321 and the second anti-wear layer 341, the wear between the push plate and the impregnated paper during the guiding of the impregnated paper is reduced as much as possible.
[0028] The working principle of this device is as follows:
[0029] First, adjust the distance between the two limiting plates 22 according to the width of the other devices. Slide the limiting plates 22 along the corresponding second slide rail 21, and then insert the insertion rod 251 through the corresponding second limiting hole 12 and second limiting hole 11 into the limiting plate 22. Then, mount the device onto the other devices so that the two limiting plates 22 abut against the outer walls of the other devices on both sides, and the lower surfaces of the two linear actuators 23 abut against the upper surfaces of the other devices.
[0030] The second step is to drive the linear actuators 23 on both sides to move closer to each other, so that the two sides of the impregnated paper are located in the two U-shaped mounting frames 31 respectively, and the two sides abut against the push plate 32 respectively.
[0031] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
