Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, specifically to an automatic adjustment device for guide rollers used in decorative paper processing. Background Technology

[0002] In the decorative paper processing, the automatic guide roller adjustment device is a key component to ensure the flat transport of the paper. Furthermore, the processing is incorporated into the transport process; however, the length specifications of existing traditional guide rollers are relatively fixed, leading to the following prominent problems with the equipment:

[0003] First, the existing guide rollers have a limited range of length adaptability. When processing ultra-wide decorative paper, specific models of long guide rollers must be replaced to meet production requirements. This rigid matching requirement not only increases equipment configuration costs but also necessitates the stockpiling of various specifications of spare guide rollers on the production line, significantly increasing the company's equipment investment and warehousing management costs. Furthermore, the replacement process requires substantial manpower and time. Second, during the transport of decorative paper, the tension of the paper must be maintained at all times. If the tension is not up to standard, it directly affects the quality of the decorative paper processing, resulting in the relatively poor practicality of automatic guide roller adjustment devices for decorative paper processing.

[0004] Therefore, in order to solve the above problems, how to design an automatic adjustment device for guide rollers in decorative paper processing is a technical problem that the industry urgently needs to solve. Utility Model Content

[0005] The purpose of this invention is to provide an automatic adjustment device for guide rollers in decorative paper processing, so as to solve the problem mentioned in the background art that the length of the guide rollers cannot be adjusted in real time.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An automatic adjustment device for guide rollers in decorative paper processing includes a set of main boxes arranged symmetrically, wherein an adjustment component is provided at the bottom of the main box and a pushing component is provided at the front end of the main box;

[0008] The main housing is equipped with a drive assembly, and the drive assembly is equipped with a rotating frame. The rotating frame is located at the rear of the main housing and above the control assembly. The rotating frame is equipped with an installation cavity and a positioning cavity. Several sets of extension assemblies are detachably connected to the rear of the rotating frame.

[0009] Preferably, the drive assembly includes a rotary motor located inside the main housing. The drive end of the rotary motor is provided with a rotary shaft located on the rear side of the main housing, and a rotary frame is provided on the outer circumference of the rotary shaft.

[0010] Preferably, the extension assembly includes a mounting frame, a sliding cavity is provided inside the mounting frame, a limiting rod is provided on the inner wall of the sliding cavity, a set of symmetrical locking blocks are provided on the outer sleeve of the limiting rod, a plurality of sets of telescopic springs are provided between the set of locking blocks, a set of symmetrical locking cavities is provided inside the mounting frame, and the locking blocks are locked into the mounting cavity and positioning cavity of the rotating frame.

[0011] Preferably, the pushing assembly includes a pushing motor located inside the main housing. The driving end of the pushing motor is provided with a pushing shaft, which is located between the driving assembly and the control assembly. The main housing is provided with a pushing rod, and the outer surface of the pushing shaft is provided with a movable guide slider. The guide slider is threadedly engaged with the pushing shaft, and the push rod passes through the guide slider. A clamping assembly is provided on the side of the guide slider.

[0012] Preferably, the clamping assembly includes a main clamping plate, which is located on one symmetrical side end face of the main housing and above the control assembly. The main clamping plate is provided with a pneumatic telescopic cylinder, and a secondary clamping frame is provided at one extended end of the pneumatic telescopic cylinder.

[0013] Preferably, the rear end of the main clamping plate is provided with an abutment plate, which is located behind the sliding cavity. An insertion frame is rotatably provided on the abutment plate, and the insertion frame is inserted into the last set of sliding cavities.

[0014] Preferably, the control component includes a base plate frame, on which a threaded motor is fixedly mounted. The drive end of the threaded motor is provided with a threaded screw, and the outer surface of the threaded screw is provided with a set of threaded sliders that can move in opposite directions. Each set of threaded sliders is respectively connected to a symmetrical set of main housings. A controller is provided on the base plate frame.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. The advantages of this utility model are as follows: Based on the width of the decorative paper, the drive motor is started, thereby driving the drive shaft to rotate, which in turn drives the guide slider to move along the drive shaft and the drive rod, thus providing sufficient space for the assembly of the rotating frame and the extension component. When a symmetrical set of locking blocks is inserted into the mounting cavity and positioning cavity of the rotating frame, the elastic force of the telescopic spring ensures the rapid assembly of the rotating frame and the extension component. The extension component also has a locking cavity, ensuring that the locking blocks of another set of extension components are inserted into the sliding cavity and the locking cavity, thus repeating the above steps. During disassembly, the extension component can be removed by pulling the symmetrical locking blocks along the limit rod, thus realizing the segmented installation of the same type of extension component, thereby ensuring the rapid disassembly of the extension component and the rotating frame. The principle is the same for the same type of extension component, thus simplifying the tedious disassembly process and ensuring the efficiency of disassembly. Furthermore, it can be adjusted in real time according to the actual width of the decorative paper on site, thus meeting the needs of decorative paper of any width. Moreover, since the extension component is small in size and occupies little space, it is easy to store and preserve.

[0017] 2. The advantages of this utility model are: the motor starts to start in reverse, thereby driving the push shaft to rotate, which in turn drives the guide slider to move along the push shaft and push rod, driving the clamping assembly, the abutment plate, and the insertion frame to move. When the insertion frame is inserted into the sliding cavity of the last set, it ensures that the two sides of the decorative paper are blocked, thereby preventing the decorative paper from deviating during the transmission process, thus ensuring the stability of subsequent processing.

[0018] 3. The advantages of this utility model are as follows: The decorative paper tube is fitted onto the outer surface of the rotating frame and extension assembly on one side, then passes between the main clamping plate and the auxiliary clamping frame, and through to the main clamping plate and the auxiliary clamping frame on the other side. The decorative paper is then manually pulled onto the rotating frame and extension assembly on the other side. Since the symmetrical set of main clamping plates and auxiliary clamping frames are kept horizontal, the decorative paper is kept horizontal, thus ensuring the horizontal alignment of the transmission and ensuring the stability during processing. Furthermore, the distance between the main clamping plate and the auxiliary clamping frame can be adjusted by controlling the pneumatic telescopic cylinder to start the telescopic movement, thereby generating resistance to the passing decorative paper and achieving the effects of deceleration and tension.

[0019] 4. The advantages of this utility model are: by starting the threaded motor, the threaded screw can be driven to rotate, thereby causing the threaded slider to move away from the main box, thus further adjusting the tension. This allows for multiple adjustments of the tension, ensuring optimal tension and improving the processing efficiency and quality of decorative paper. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0031] Example 1

[0032] See Figures 1-8This is the first embodiment of the present utility model. This embodiment provides an embodiment of an automatic adjustment device for guide rollers in decorative paper processing, including a set of main boxes 11 arranged symmetrically. The bottom of the main box 11 is provided with an adjustment component 4, and the front end of the main box 11 is provided with a push component 2.

[0033] The main housing 11 is equipped with a drive assembly 12, and the drive assembly 12 is equipped with a rotating frame 13. The rotating frame 13 is located at the rear of the main housing 11 and above the control assembly 4. The rotating frame 13 has an installation cavity 14 and a positioning cavity 15. Several sets of extension assemblies 16 are detachably connected to the rear of the rotating frame 13 to extend the installation length. By installing the extension assemblies 16 according to the length of the decorative paper, the same set of 16 can still be quickly assembled, thus ensuring that there is no need to store a large number of guide rollers, ensuring segmented installation, and further ensuring that the number of installations can be adjusted according to actual conditions, thereby ensuring adaptability.

[0034] See Figures 3-4 Specifically, the drive assembly 12 includes a rotary motor 121 located inside the main housing 11. The drive end of the rotary motor 121 has a rotating shaft 122 located at the rear of the main housing 11, and a rotating frame 13 is provided on the outer surface of the rotating shaft 122. When the rotary motor 121 is started, it drives the rotating shaft 122 and the rotating frame 13 to rotate, thereby ensuring the transmission of the decorative paper.

[0035] See Figure 4 Specifically, the extension assembly 16 includes a mounting frame 161, a sliding cavity 162 inside the mounting frame 161, a limiting rod 164 on the inner wall of the sliding cavity 162, a symmetrical set of locking blocks 165 on the outer sleeve of the limiting rod 164, a plurality of sets of telescopic springs 163 between the locking blocks 165, and a symmetrical set of locking cavities 166 inside the mounting frame 161. The locking blocks 165 are engaged into the mounting cavity 14 and positioning cavity 15 of the rotating frame 13 to achieve extended installation length. When a symmetrical set of locking blocks 165 is inserted into the mounting cavity 14 and the positioning cavity 15, the elastic force of the telescopic spring 163 ensures the rapid assembly of the rotating frame 13 and the extension assembly 16. The extension assembly 16 is provided with a locking cavity 166, which ensures that the locking blocks 165 of another set of extension assemblies 16 are inserted into the sliding cavity 162 and the locking cavity 166. By repeating the above steps, segmented installation of the same type of extension assembly 16 is achieved.

[0036] See Figure 3Specifically, the pushing assembly 2 includes a pushing motor 21 located inside the main housing 11. The driving end of the pushing motor 21 has a pushing shaft 22 located between the driving assembly 12 and the control assembly 4. The main housing 11 has a pushing rod 23. The outer surface of the pushing shaft 22 has a movable guide slider 24 threadedly engaged with the pushing shaft 22. The guide slider 24 is penetrated by the pushing rod 23, and a clamping assembly 25 is provided on the side of the guide slider 24. When the length of the rotating frame 13 needs to be extended, the pushing motor 21 is started, causing the pushing shaft 22 to rotate. This causes the guide slider 24 to move along the pushing shaft 22 and the pushing rod 23, thereby increasing the assembled length of the rotating frame 13 and the extension assembly 16.

[0037] See Figure 7 Specifically, the clamping assembly 25 includes a main clamping plate 251, which is located on one symmetrical side end face of the main housing 11 and above the control assembly 4. A pneumatic telescopic cylinder 252 is mounted on the main clamping plate 251, and a secondary clamping frame 253 is provided at one extended end of the pneumatic telescopic cylinder 252. When the pneumatic telescopic cylinder 252 begins to extend or retract, it adjusts the distance between the main clamping plate 251 and the secondary clamping frame 253, thereby ensuring that the decorative paper is kept at the same horizontal level and also providing a gradual deceleration effect.

[0038] See Figures 3-5 Specifically, the rear end of the main clamping plate 251 is provided with an abutment plate 254, which is located behind the sliding cavity 162. An insertion frame 255 is rotatably provided on the abutment plate 254, and the insertion frame 255 is inserted into the last set of sliding cavities 162.

[0039] See Figure 6 Specifically, the control component 4 includes a base frame 41, on which a threaded motor 42 is fixedly mounted. The drive end of the threaded motor 42 is provided with a threaded screw 43. The outer surface of the threaded screw 43 is provided with a set of threaded sliders 44 that can move in opposite directions. Each set of threaded sliders 44 is respectively connected to a symmetrical set of main housings 11. A controller 45 is provided on the base frame 41. By starting the threaded motor 42, the threaded screw 43 begins to rotate, thereby causing the threaded sliders 44 to move away from the main housings 11, thus further adjusting the tightness.

[0040] Optionally, controller 45 can be a Siemens PLC controller to control the motor and valve.

[0041] Specific workflow:

[0042] In use, the drive motor 21 is started according to the width of the decorative paper, which drives the drive shaft 22 to rotate. This causes the guide slider 24 to move along the drive shaft 22 and the drive rod 23, thus providing sufficient space for the assembly of the rotating frame 13 and the extension assembly 16. When a set of symmetrical locking blocks 165 are inserted into the mounting cavity 14 and the positioning cavity 15 of the rotating frame 13, the elastic force of the telescopic spring 163 ensures the rapid assembly of the rotating frame 13 and the extension assembly 16. The inner cavity is also provided with a locking cavity 166, which ensures that the locking block 165 of another set of extension components 16 is inserted into the sliding cavity 162 and the locking cavity 166, thereby repeating the above steps. When disassembling, the extension component 16 can be removed by simply pulling the symmetrical locking block 165 along the limiting rod 164. This realizes the segmented installation of the same type of extension component 16, thereby ensuring quick disassembly of the extension component 16 and the rotating frame 13. The principle is the same for the same type of extension component 16, thereby realizing the adjustment according to the width of the decorative paper.

[0043] When the drive motor 21 starts in reverse, it drives the drive shaft 22 to rotate, which in turn drives the guide slider 24 to move along the drive shaft 22 and the drive rod 23, which in turn drives the clamping assembly 25, the abutment plate 254, and the insertion frame 255 to move. When the insertion frame 255 is inserted into the last set of sliding cavities 162, it ensures that the decorative paper is blocked on both sides.

[0044] When the decorative paper tube is fitted onto the outer surface of the rotating frame 13 and extension assembly 16 on one side, it passes between the main clamping plate 251 and the auxiliary clamping frame 253, and then through to the other side between the main clamping plate 251 and the auxiliary clamping frame 253. The decorative paper is then manually pulled onto the rotating frame 13 and extension assembly 16 on the other side. Since the symmetrical set of main clamping plates 251 and auxiliary clamping frames 253 are kept horizontal, the decorative paper is kept horizontal, thus ensuring the horizontal line of transmission and the stability during processing. Furthermore, the distance between the main clamping plate 251 and the auxiliary clamping frame 253 can be adjusted by controlling the telescopic movement of the pneumatic telescopic cylinder 252, thereby generating resistance to the passing decorative paper and achieving a deceleration and tensioning effect.

[0045] Furthermore, the starting of the threaded motor 42 can drive the threaded screw 43 to start rotating, thereby causing the threaded slider 44 to start moving away from the main housing 11, thus further adjusting the tension.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
