Description

Technical Field

[0001] The present invention relates to the field of cleaning racks, and specifically to a transition rack for adhesive films that is convenient for cleaning. Background Technique

[0002] In the process of adhesive film processing and use, the transition rack, as an important auxiliary tool, plays an indispensable role. It is mainly used to support and transfer the rolled adhesive film, ensuring that the adhesive film remains flat and stable during processing and transfer, and avoiding damage or contamination caused by external factors. However, with the continuous progress of adhesive film processing technology and the continuous expansion of application fields, traditional transition racks can no longer meet the needs of modern production, and there are a series of problems that need to be solved urgently.

[0003] First, during the process of conveying and conducting the adhesive film by traditional transition racks, in order to clean the guided adhesive film, a cleaning mechanism needs to be additionally installed on the transition rack, which not only makes the equipment structure cumbersome, but also the used cleaning structure needs to be disassembled and stored separately.

[0004] In addition, traditional transition racks are not convenient for moving and transferring. During the process of adhesive film processing and use, the transition rack often needs to be moved from one position to another for the next operation. However, most traditional transition racks are made of heavy materials and are very difficult to move, which not only consumes manpower and material resources, but may also damage the adhesive film.

DETAILED DESCRIPTION

[0037] In order to clearly and completely describe the objectives, technical solutions of the present invention and make its advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0038] Embodiment 1. Please refer to Figure 1-Figure 4 , the present invention provides a technical solution: a transition rack for a film that is easy to clean, including a support frame 1. A lifting frame 4 is inserted into the top of the support frame 1. A pulley 7 is installed at the bottom end of the lifting frame 4. The height of the lifting frame 4 is greater than that of the support frame 1. A connecting plate 10 is fixed on the side plate of the support frame 1. An assembly groove 11 is formed on the surface of the connecting plate 10. A clamping block 13 is inserted into the surface of the assembly groove 11. An assembly plate 14 is inserted into the interior of the assembly groove 11. The assembly plate 14 squeezes and pushes the clamping block 13 to clamp the side plate of the lifting frame 4. A guide roller 31 is rotatably connected to the side plate of the lifting frame 4. An installation sleeve 33 is inserted into the top plate of the lifting frame 4. A cleaning frame 34 is inserted into the interior of the installation sleeve 33. A pressure roller 37 and a brush plate 39 are provided at the bottom end of the cleaning frame 34.

[0039] Embodiment 2. Refer to the attached Figure 14 and Figure 15 As shown, on the basis of Embodiment 1, in order to facilitate the sliding transfer of the transition rack; the support frame 1 is in a "C"-shaped plate structure. A rubber cushion 2 is fixed on the bottom surface of the support frame 1. Side grooves 3 are formed on both of the two parallel side plates of the support frame 1. The lifting frame 4 is in an inverted "U"-shaped plate structure. The two parallel side plates of the lifting frame 4 are respectively slidably connected in the two side grooves 3; Installation grooves 1 are formed on the bottom surfaces of the two parallel side plates of the lifting frame 4. A limiting shaft 1 6 is fixed on the surface of the installation groove 1. The limiting shaft 1 6 is in a "T"-shaped cylinder. The pulley 7 is sleeved on the cylinder of the limiting shaft 1 6. Handles 28 are fixed on the top surfaces of the two parallel side plates of the support frame 1. A grasping opening is formed on the top plate of the handle 28.

[0040] When the transition rack is in use, the lifting frame 4 is adjusted to a suspended state. At this time, the rubber cushion 2 is placed between the support frame 1 and the ground to play an anti-slip role; the lifting frame 4 is clamped by the clamping block 13 to prevent it from slipping. In order to ensure the stability of the support frame 1 when placed, a counterweight can be selected to be placed on the bottom plate of the support frame 1; and a storage box 40 is installed between the two side plates of the support frame 1 for storing tools, and a support plate 41 is used for placing the rolled film.

[0041] When it is necessary to transfer the rolled film and the transition frame after use, pull the assembling plate 14 upward. When the assembling plate 14 no longer pushes the clamping block 13, the lifting frame 4 is no longer clamped by the clamping block 13, and then lift the support frame 1 until the pulley 7 at the bottom end of the lifting frame 4 touches the ground. At this time, push the assembling plate 14 to squeeze the clamping block 13 to clamp the lifting frame 4 to prevent the support frame 1 from falling. At this time, push the transition frame to slide, which not only facilitates the turnover of the transition frame, but also satisfies the load-bearing and transportation function of the rolled film.

[0042] Example 3, refer to the attached Figure 6 、 Figures 8 to 13 As shown, on the basis of embodiment 2, in order to realize the clamping and fixing of the lifting frame 4 after the position is determined; the connecting plate 10 is fixed on the two parallel side walls of the side groove 3, and the top surface of the connecting plate 10 is provided with an assembling groove 11, which is a "T"-shaped groove. The height of the assembling groove 11 is less than the height of the connecting plate 10, and the assembling plate 14 is a "T"-shaped plate. The surface of the assembling plate 14 is fixed with a slider 15, and the slider 15 is slidably connected in the slide groove 16, and the slide groove 16 is provided on the surface of the connecting plate 10; the surface of the assembling groove 11 is provided with a "T"-shaped groove. A through-hole 12 is provided on the surface, and a clamping block 13 is inserted into the through-hole 12. An inclined surface is provided on the top surface of one end of the clamping block 13 extending to the assembly groove 11, and a notch 17 is provided on the other end of the clamping block 13. A baffle 18 is inserted into the inside of the notch 17, and a rubber support block 19 is fixed between the baffle 18 and the notch 17; an installation groove 2 8 is provided on the side panel of the lifting frame 4, and a rubber strip 9 is fixed on the surface of the installation groove 2 8. The assembly plate 14 pushes the clamping block 13 to clamp the rubber strip 9. At this time, the rubber support block 19 is compressed and elastically deformed.

[0043] When the assembling plate 14 blocks one side of the clamping block 13, the clamping block 13 clamps the rubber strip 9, and the rubber strip 9 is pressed and inserted into a part of the groove 17, thereby increasing the anti-slip firmness between the clamping block 13 and the lifting frame 4, and the rubber support block 19 is deformed under pressure, and a "cross" groove is opened at one end of the clamping block 13, and a rubber block is fixed inside the clamping block 13. The thickness of the rubber block is greater than the depth of the clamping block 13. At this time, the rubber strip 9 rebounds and pushes the rubber block at the end of the clamping block 13 tightly against the surface of the assembling plate 14 to prevent the assembling plate 14 from bumping. That is, when the assembling plate 14 squeezes the clamping block 13 to limit it, the clamping block 13 reversely squeezes the assembling plate 14 to prevent bumping, that is, the assembling plate 14 and the clamping block 13 limit each other.

[0044] In order to limit the assembled plate 14, a second notch 20 is formed on the top surface of the assembled plate 14. A second limiting shaft 21 is fixed to the bottom surface of the second notch 20. The second limiting shaft 21 penetrates through the blocking bar 22. One end of the blocking bar 22 extends into the embedding groove 23. The embedding groove 23 is formed on the side wall of the assembling groove 11. The surface of the assembled plate 14 is provided with the embedding groove 23. The embedding groove 23 is in the shape of a concave groove. The embedding groove 23 is communicated with the second notch 20. A bushing 24 is inserted into the inside of the embedding groove 23. The bushing 24 is in the shape of a U-shaped plate structure. A through hole 25 is formed on the surface of the bushing 24. A guide rod 26 is inserted into the inside of the through hole 25. The guide rod 26 is fixed between the top surface and the bottom surface of the bottom groove body of the embedding groove 23. A spring 27 is sleeved on the rod body of the guide rod 26. When the spring 27 is in the initial state, the top end of the supporting bushing 24 extends out of the embedding groove 23.

[0045] In order to firmly limit the assembled plate 14, one end of the blocking bar 22 is toggled to extend into the jack 43. At this time, the blocking bar 22 blocks above the assembled plate 14 to prevent the assembled plate 14 from jolting. At this time, the two side plates of the bushing 24 respectively block on both sides of the blocking bar 22, so as to prevent the blocking bar 22 from being pulled out of the jack 43. When it is necessary to cancel the limit of the assembled plate 14 on the clamping block 13, the bushing 24 is squeezed to retract into the embedding groove 23. At this time, the bushing 24 squeezes the spring 27 to generate elastic deformation. At the same time, the blocking bar 22 is toggled to rotate around the second limiting shaft 21 into the second notch 20. At this time, the blocking bar 22 blocks above the bushing 24. The spring 27 rebounds to push the bushing 24 against the bottom surface of the blocking bar 22 to brake the blocking bar 22. At this time, the assembled plate 14 is lifted upward. The assembled plate 14 drives the slider 15 to slide along the sliding groove 16 until the slider 15 is blocked by the top surface of the sliding groove 16. At this time, the assembled plate 14 is above the clamping block 13. The clamping block 13 is no longer squeezed by the assembled plate 14, so as to no longer clamp the lifting frame 4.

[0046] Embodiment 4. Refer to the appendix Figures 16 to 18As shown, on the basis of the third embodiment, in order to realize the cleaning of the film during the conveying process of the guide roller 31, the two parallel side plates of the lifting frame 4 are provided with a mounting opening 29, the interior of the mounting opening 29 is fixed with a bearing 30, and the two ends of the guide roller 31 are respectively inserted into the inner rings of the two bearings 30; the top surface of the lifting frame 4 is provided with a mounting opening 32, and the mounting sleeve 33 is a "T"-shaped frame structure, the top plate length of the mounting sleeve 33 is greater than the slot length of the mounting opening 32, the bottom end of the mounting sleeve 33 is inserted into the mounting opening 32, and the top plate of the mounting sleeve 33 is fixed to the top surface of the lifting frame 4 by screws, and the cleaning frame 34 is inserted in In the inner ring opening of the mounting sleeve 33, an elastic belt 35 is fixed to the top surface of the cleaning frame 34, and both ends of the elastic belt 35 are fixed to the top surface of the mounting sleeve 33, and the two ends of the elastic belt 35 are distributed on both sides of the inner ring opening of the mounting sleeve 33. A receiving groove 36 is provided on the bottom surface of the cleaning frame 34, and the receiving groove 36 is an inverted "U"-shaped groove. A limiting shaft three 42 is fixed between two parallel side walls of the receiving groove 36, and a pressure roller 37 is sleeved on the rod body of the limiting shaft three 42, and the bottom end of the pressure roller 37 is below the bottom surface of the cleaning frame 34. Wing grooves 38 are provided on both sides of the cleaning frame 34, and the brush plate 39 is fixed in the wing groove 38 by screws.

[0047] When the mounting sleeve 33 is installed in the mounting port 2 32, when the winding device winds the film, the film passes between the pressure roller 37 and the guide roller 31, and the cleaning frame 34 falls, so that the bristles of the pressure roller 37 and the brush plate 39 contact the film, the pressure roller 37 flattens the film, and the brush plate 39 sweeps away the particles on the film. The pressure roller 37 and the guide roller 31 can accommodate films of different thicknesses. When the thick film passes between the guide roller 31 and the pressure roller 37, the mounting sleeve 33 is supported by the elastic belt 35 to produce elastic deformation, and the elastic belt 35 rebounds and presses down the cleaning frame 34, so that the film is clamped between the pressure roller 37 and the guide roller 31.

[0048] Example 5, based on Example 4, proposes a method for using a transition rack for an adhesive film that is easy to clean, comprising the following steps:

[0049] Step 1: When the transition frame is in use, the lifting frame 4 is adjusted to a suspended state. At this time, the rubber pad 2 is placed between the support frame 1 and the ground to prevent slipping. The lifting frame 4 is clamped by the clamping block 13 to prevent it from slipping. In order to ensure the stability of the support frame 1 when it is placed, a counterweight can be placed on the bottom plate of the support frame 1. A storage box 40 is installed between the two side plates of the support frame 1 for storing tools, and a support plate 41 is used to place the rolled film.

[0050] Step 2: When the rolled film and the transition frame after use need to be transferred, the assembling plate 14 is pulled upward. When the assembling plate 14 no longer pushes the clamping block 13, the lifting frame 4 is no longer clamped by the clamping block 13, and then the support frame 1 is lifted until the pulley 7 at the bottom end of the lifting frame 4 touches the ground. At this time, the assembling plate 14 is pushed to squeeze the clamping block 13 to clamp the lifting frame 4 to prevent the support frame 1 from falling. At this time, the transition frame can be pushed to slide, which not only facilitates the turnover of the transition frame, but also satisfies the load-bearing and transportation function of the rolled film.

[0051] Step 3: When the assembling plate 14 blocks one side of the clamping block 13, the clamping block 13 clamps the rubber strip 9. After the rubber strip 9 is compressed, it is inserted into a part of the notch 17, thereby increasing the anti-slip firmness between the clamping block 13 and the lifting frame 4, and the rubber support block 19 is deformed under pressure. A "cross" groove is provided at one end of the clamping block 13, and a rubber block is fixed inside the clamping block 13. The thickness of the rubber block is greater than the depth of the clamping block 13. At this time, the rubber strip 9 rebounds and pushes the rubber block at the end of the clamping block 13 tightly against the surface of the assembling plate 14 to prevent the assembling plate 14 from bumping. That is, when the assembling plate 14 squeezes the clamping block 13 to limit its position, the clamping block 13 reversely squeezes the assembling plate 14 to prevent it from bumping. That is, the assembling plate 14 and the clamping block 13 limit each other.

[0052] Step 4: In order to achieve a firm limit on the assembly plate 14, one end of the stop bar 22 is pushed into the insertion hole 43. At this time, the stop bar 22 blocks the upper part of the assembly plate 14 to prevent the assembly plate 14 from bumping; at this time, the two side plates of the clamping sleeve 24 are respectively blocked on both sides of the stop bar 22, thereby preventing the stop bar 22 from being withdrawn from the insertion hole 43; when it is necessary to cancel the limit of the clamping block 13 by the assembly plate 14, the clamping sleeve 24 is squeezed and retracted into the embedding groove 23. At this time, the clamping sleeve 24 squeezes the spring 27 to produce elastic deformation, and at the same time, the stop bar 2 is pushed. 2 is rotated with the second limiting shaft 21 as the central axis to the second notch 20. At this time, the stop bar 22 is blocked above the clamping sleeve 24, and the spring 27 rebounds to push the clamping sleeve 24 against the bottom surface of the stop bar 22, thereby braking the stop bar 22. At this time, the assembly plate 14 is pulled upward, and the assembly plate 14 drives the slider 15 to slide along the slide groove 16 until the slider 15 is blocked by the top surface of the slide groove 16. At this time, the assembly plate 14 is above the clamping block 13, and the clamping block 13 is no longer squeezed by the assembly plate 14, thereby no longer clamping the lifting frame 4;

[0053] Step 5: After the mounting sleeve 33 is mounted on the mounting opening 2 32, when the winding device winds up the film, the film passes between the pressure roller 37 and the guide roller 31, and the cleaning frame 34 falls, so that the bristles of the pressure roller 37 and the brush plate 39 contact the film, the pressure roller 37 flattens the film, and the brush plate 39 sweeps away the particles on the film. The pressure roller 37 and the guide roller 31 can accommodate films of different thicknesses. When the thick film passes between the guide roller 31 and the pressure roller 37, the mounting sleeve 33 is supported by the elastic belt 35 to produce elastic deformation, and the elastic belt 35 rebounds and presses down the cleaning frame 34, so that the film is clamped between the pressure roller 37 and the guide roller 31.

[0054] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
