Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production, in particular to a bubble inspection and processing device for producing electrical adhesive tape. Background Art

[0002] As an important material in daily production and life, tape is widely used in packaging, bundling, sealing and other fields. In the tape production process, since the tape needs to be wrapped around the sleeve layer by layer, a large number of bubbles will be present in the tape during the winding process, thus affecting the appearance of the product.

[0003] In actual operation, when the rewinding machine is performing the rewinding operation, the method to remove the bubbles is to use a traditional mechanical pressure roller to squeeze the tape, thereby pressing out and removing the bubbles in the tape.

[0004] However, in practical use, although the mechanical pressure roller can squeeze the bubbles, it cannot change in real time with the change in the winding diameter of the rewinding roller, resulting in the pressure of the pressure roller gradually increasing as the diameter of the rewinding roller continues to increase, which can easily cause excessive pressure to damage the tape on the rewinding roller. At the same time, the use of mechanical pressure roller squeezing alone has limited effect on removing bubbles and cannot improve the efficiency of bubble removal. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0027] Example: Figure 1 - Figure 8 As shown, a bubble inspection and processing equipment for producing electrical tapes comprises a frame 2, on which a parent roll 12 and a rewinding roll 8 are rotatably mounted in sequence, the parent roll 12 and the rewinding roll 8 are arranged correspondingly at the two sides of the frame 2 in sequence, a quick release mechanism is arranged at the connection between the parent roll 12 and the rewinding roll 8 and the frame 2, a tension group adjustment mechanism is arranged at the interval between the parent roll 12 and the rewinding roll 8 on the frame 2, a fine-tuning drive mechanism for driving the tension group adjustment mechanism is arranged on one side of the frame 2, a limiting mechanism is arranged on the fine-tuning drive mechanism, a bubble squeezing processing mechanism which can be arranged in contact with the rewinding roll 8 is arranged on the frame 2 above the rewinding roll 8, a main power driving mechanism is arranged on one side of the frame 2, and the main power driving mechanism is used to drive the bubble squeezing processing mechanism to operate simultaneously with the parent roll 12 and the rewinding roll 8;

[0028] In actual use, the mother roll 12 and the rewinding roll 8 are installed through the quick-release mechanism. After the installation is completed, the tape on the mother roll 12 is pulled out, and the tape is passed through the tension group adjusting mechanism and fixed on the rewinding roll 8. At this time, the tension group adjusting mechanism is preferentially adjusted through the fine-tuning drive mechanism to change the tension of the tape on the tension group adjusting mechanism. After the tension becomes large, the tape can be tightened, thereby avoiding the occurrence of bubbles in the loose tape during rewinding. After the adjustment is completed, the tension group adjusting mechanism is fixed through the limiting mechanism. At this time, the main power driving mechanism can be driven to cause the mother roll 12 to unwind and the rewinding roll 8 to rewind. While the rewinding roll 8 is rewinding, the bubble squeezing processing mechanism can squeeze the tape wound on the rewinding roll 8, thereby avoiding the occurrence of bubbles on the tape after rewinding.

[0029] The bubble extrusion processing mechanism includes a threaded screw 18 and a fixed frame 16. The threaded screw 18 is installed at the inner walls of both sides of the frame 2 and is located directly above the rewinding roller 8. The inner walls of both sides of the frame 2 are fixedly installed with a first protective frame 13, and the first protective frame 13 is covered on the outside of the threaded screw 18. Two groups of symmetrically arranged movable blocks 14 are threadedly installed on the threaded screw 18. The built-in threads of the two groups of movable blocks 14 are oppositely arranged. The bottoms of the two groups of movable blocks 14 are hingedly installed with connecting rods 19. The two groups of connecting rods 19 are cross-hinged and connected. The two sides of the fixed frame 16 The inner wall is rotatably mounted with a squeezing roller 17, which is fitted with the rewinding roller 8. A second slide groove 20 is provided at the top of the fixed frame 16, and slide bars 22 are fixedly mounted on the inner walls on both sides of the second slide groove 20. Two groups of second sliders 15 corresponding to the movable blocks 14 are slidably mounted on the slide bars 22, and the two groups of second sliders 15 are hingedly connected to the free ends of the connecting rods 19 in sequence. Limiting grooves are provided at the inner walls on both sides of the frame 2, located at the front and rear sides of the fixed frame 16, and guide blocks 21 are slidably mounted in the limiting grooves, and the guide blocks 21 are fixedly connected to the fixed frame 16;

[0030] After the main power driving mechanism is started, the parent roll 12 and the rewinding roll 8 rotate at the same time, and the threaded screw 18 rotates to cause the two groups of movable blocks 14 to move away from each other, causing the ends of the two groups of connecting rods 19 to separate from each other, so that the squeezing roller 17 can fit with the rewinding roll 8 in real time, thereby adapting to the situation where the rewinding roll 8 slowly becomes larger after winding the tape, and at the same time, it can also ensure that the squeezing roller 17 is always in a squeezing state to avoid the occurrence of bubbles during rewinding.

[0031] The tension group adjustment mechanism includes a fixed tension roller 10, which is installed on a side close to the mother roll 12, and the axis of the fixed tension roller 10 is lower than the axis of the mother roll 12. The inner walls of both sides of the frame 2 are provided with first slide grooves 6, and the inner top and bottom of the first slide groove 6 are rotatably installed with a second threaded rod 36, and the first slider 7 is threadedly installed on the second threaded rod 36. The corresponding side wall of the first slider 7 is rotatably installed with a movable tension roller 9, and a second protective frame 38 is fixedly installed on the frame 2, and the second protective frame 38 is connected to the first The slide groove 6 is connected, and a mounting rod 34 is rotatably installed on the inner walls on both sides of the second protective frame 38. The mounting rod 34 is located inside the first slide groove 6 and a second gear 37 is fixedly installed on the top section of the second threaded rod 36. A first gear 35 meshing with the second gear 37 is fixedly installed. The inner walls on both sides of the frame 2 are located just above the center of the fixed tension roller 10 and the movable tension roller 9 and a tension adjustment roller 11 is rotatably installed. The tension adjustment roller 11 forms a triangular structure with the fixed tension roller 10 and the movable tension roller 9.

[0032] By fine-tuning the driving mechanism, the tension adjustment roller 11 is caused to rotate, thereby pulling the tape mounted on the tension adjustment roller 11. At the same time, when the tension adjustment roller 11 rotates, the active tension roller 9 moves longitudinally, thereby pulling the tape mounted on the active tension roller 9, further changing the tension, thereby tightening the tape and preventing bubbles from forming when the loose tape is wound.

[0033] like Figure 1 , Figure 4 , Figure 7 As shown, the main force driving mechanism includes a driving sprocket 26, a driving gear 28, a driven sprocket 27 and a mounting frame 4. The driving sprocket 26 and the driving gear 28 are rotatably mounted on one side wall of the frame 2. The rotating shafts of the driving sprocket 26 and the driving gear 28 are fixedly connected to the driving shafts of the parent roll 12 and the rewinding roll 8 in sequence. A driven sprocket 27 horizontally arranged with the driving sprocket 26 is fixedly mounted on the outer side of the driving gear 28. A chain 25 is sleeved on the driving sprocket 26 and the driven sprocket 27. A mounting frame 4 is fixedly mounted on the outer side of the driving sprocket 26 on the frame 2. A motor 5 is fixedly mounted on the mounting frame 4. The output end of the motor 5 transversely penetrates the mounting frame 4 and is fixedly connected to the rotating shaft of the driving sprocket 26. A driven gear 1 is rotatably mounted on the frame 2 above the driving gear 28. The diameter of the driven gear 1 is larger than the diameter of the driving gear 28. The rotating shaft of the driven gear 1 is horizontally hooked to press the frame 2 and is fixedly connected to the threaded screw 18.

[0034] The motor 5 is driven to preferentially drive the driving sprocket 26 to rotate. At this time, the parent roll 12 rotates. At the same time, due to the chain 25 on the driving sprocket 26, the driven sprocket 27 is driven to rotate. The driven sprocket 27 also drives the driving gear 28 to rotate. The driving gear 28 drives the rewinding roll 8 to rotate for the winding operation. Since the driven gear 1 is meshed with the driving gear 28, the driven gear 1 rotates, thereby driving the threaded screw 18 to rotate.

[0035] like Figure 1 , Figure 4 , Figure 6 As shown, the fine-tuning drive mechanism includes a first pulley 23, a transmission belt 24, a second pulley 31 and a handwheel 3. The first pulley 23 and the second pulley 31 are rotatably installed on the frame 2. The rotating shafts of the first pulley 23 and the second pulley 31 transversely penetrate the frame 2 and are fixedly connected to the mounting rod 34 and the rotating shaft of the tension adjustment roller 11 in sequence. The transmission belt 24 is sleeved on the first pulley 23 and the second pulley 31. The handwheel 3 is fixedly installed on the outer wall of the second pulley 31, and the handwheel 3 and the second pulley 31 are coaxially arranged.

[0036] By rotating the second pulley 31 through the hand wheel 3, the second pulley 31 directly drives the tension adjustment roller 11 to rotate for adjustment, and at the same time causes the second pulley 31 to drive the first pulley 23 to rotate through the transmission belt 24. At this time, the first pulley 23 drives the mounting rod 34 to rotate, thereby completing the adjustment of the movable tension roller 9.

[0037] like Figure 4 and Figure 6 As shown, the limiting mechanism includes a mounting plate 29, on which a first threaded rod 32 is threadedly mounted, and a handle is fixedly mounted on one end of the first threaded rod 32 located above the mounting plate 29, and a limiting plug 33 is rotatably mounted on one end of the first threaded rod 32 located below the mounting plate 29, and teeth 30 are fixedly mounted on the outer wall of the second pulley 31, and the limiting plug 33 is meshed with the teeth 30, and the top of the limiting plug 33 is located on both sides of the first threaded rod 32 and guide rods are fixedly mounted, and the guide rods are slidably connected to the mounting plate 29.

[0038] After the fine-tuning drive mechanism is adjusted, the user rotates the first threaded rod 32 by the handle, so that the limiting plug 33 is inserted into the gap between the teeth 30 on the second pulley 31, and the second pulley 31 is fixedly limited.

[0039] like Figure 8As shown, the quick-release mechanism includes a winding roller 42 and a fixed sleeve 41. The winding roller 42 is the central axis roller of the mother winding roller 12 and the rewinding roller 8. The inner walls of both sides of the frame 2 are rotatably mounted with fixed sleeves 41. A group of fixed sleeves 41 connected to the main power driving mechanism is provided with a special-shaped slot 43. A group of fixed sleeves 41 connected to the main power driving mechanism is threadedly mounted with a limit ring 44 on the outer wall. The winding roller 42 is plug-connected with the two groups of fixed sleeves 41, and conventional plug blocks 40 and special-shaped plug blocks 39 matching the two groups of fixed sleeves 41 are fixedly mounted on both ends of the winding roller 42 in sequence.

[0040] The user places the mother roll 12 and the rewinding roll 8 in the fixing sleeve 41. At this time, the conventional plug-in block 40 is preferentially plugged into the corresponding fixing sleeve 41, and the special-shaped plug-in block 39 is slid into the special-shaped slot 43. At this time, the limiting ring 44 is rotated to move the limiting ring 44 to the outside of the special-shaped plug-in block 39, and the fixed limit can be completed.

[0041] like Figure 3 As shown, the squeezing roller 17 is made of metal and is an electromagnetic heating roller, and a temperature sensor is arranged inside the squeezing roller 17 .

[0042] During the tape production process or before use, heating can soften the tape, making it easier to adhere to the surface and remove bubbles, but it should be noted that the heating temperature and time should be moderate to avoid damage to the tape.

[0043] like Figure 2 As shown, the fixed tension roller 10 is a friction roller for placing the tape, and the outer wall of the fixed tension roller 10 is provided with a spline groove for increasing the friction force. The tension adjustment roller 11 is composed of two groups of parallel roller bodies. The initial state of the tension adjustment roller 11 is an inclined structure setting, and the initial inclination angle of the tension adjustment roller 11 is 30°.

[0044] When rewinding, increasing the tension helps the air escape, thus reducing air bubbles.

[0045] Working principle: The user places the mother roll 12 and the rewinding roll 8 in the fixing sleeve 41, and then preferentially plugs the conventional plug-in block 40 into the corresponding fixing sleeve 41, and at the same time slides the special-shaped plug-in block 39 into the special-shaped slot 43, and then rotates the limiting ring 44 so that the limiting ring 44 moves to the outside of the special-shaped plug-in block 39, and the fixed limit is completed at this time;

[0046] The motor 5 is driven to preferentially drive the driving sprocket 26 to rotate. At this time, the mother roll 12 rotates. At the same time, due to the chain 25 on the driving sprocket 26, the driven sprocket 27 is driven to rotate. The driven sprocket 27 also drives the driving gear 28 to rotate. The driving gear 28 drives the rewinding roll 8 to rotate to perform the rewinding operation. Since the driven gear 1 is meshed with the driving gear 28, the driven gear 1 rotates, thereby driving the threaded screw 18 to rotate. At this time, the mother roll 12 and the rewinding roll 8 rotate at the same time. At the same time, the rotation of the threaded screw 18 causes the two groups of movable blocks 14 to move in opposite directions, causing the ends of the two groups of connecting rods 19 to separate from each other, so that the squeezing roller 17 can fit with the rewinding roll 8 in real time, thereby adapting to the situation where the rewinding roll 8 slowly becomes larger after winding the tape, and at the same time, it can also ensure that the squeezing roller 17 is always in a squeezing state;

[0047] The second pulley 31 is rotated by the hand wheel 3, and the second pulley 31 directly drives the tension adjustment roller 11 to rotate for adjustment, and at the same time causes the second pulley 31 to drive the first pulley 23 to rotate through the transmission belt 24. At this time, the first pulley 23 drives the mounting rod 34 to rotate, and the adjustment of the active tension roller 9 is completed. The tension adjustment roller 11 rotates, thereby pulling the tape sleeved on the tension adjustment roller 11. At the same time, when the tension adjustment roller 11 rotates, the active tension roller 9 moves longitudinally, thereby pulling the tape on the active tension roller 9, further changing the tension, thereby tightening the tape and avoiding bubbles in the loose tape when winding. The user rotates the first threaded rod 32 by the handle, so that the limiting plug 33 is inserted into the gap between the teeth 30 on the second pulley 31, and the fixed limit of the second pulley 31 can be completed.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
