Description

Technical Field

[0001] The present invention relates to the technical field of tape production, and more particularly to the storage and unwinding technology of the fabric for processing cloth-based tapes, specifically a fabric storage mechanism with automatic tension control. Background Technique

[0002] During the production process of tapes, such as cloth-based tapes and flannelette tapes, a storage mechanism is required to store the tape substrate to ensure the continuous stability of feeding, maintain the stable tension of the substrate, and play a buffering role to avoid breakage of the substrate during the feeding and processing process;

[0003] For example, a double-layer film storage device for a coater with the publication number CN 207312742 U proposes to store and release a certain length of film by controlling the up and down movement of the movable guide roller plate to achieve the purpose of film storage. The movable guide roller plate is raised to the highest position and maintained. When changing the film, the motor receives the electro-control signal of the coater, drives the lead screw to rotate, and lowers the movable guide roller plate to the required position at the required speed. Thus, the film material at the feeding end remains stationary, and while ensuring that the material receiving mechanism can complete the material receiving normally, the discharging end can still output the film material continuously at a normal coating speed to supply the subsequent stations of the coater. When adjusting the roll change and material receiving, there is no need to stop the machine or decelerate, and the roll change and material receiving can be directly carried out, which has the advantages of simple adjustment, real-time controllability, and high efficiency;

[0004] Another example is a film material storage and unwinding mechanism with the publication number CN 210084564 U, which includes a frame, a movable plate, a fixed roller group, a movable roller group, a lifting device, a tension sensor, and a PLC controller. The fixed roller group includes at least two fixed rollers rotatably connected to the frame; the movable plate is slidably fitted on the frame; the movable roller group includes at least one movable roller rotatably connected to the movable plate, and the film material is alternately connected to the fixed rollers and the movable rollers in a wave shape; the lifting device is arranged on the frame and connected to the movable plate; the tension sensor is used to collect the tension signal of the film material; the PLC controller is used to control the movable roller group to move towards the direction close to the fixed roller group to release the film material and move away from the fixed roller group to store the film material according to the tension signal of the tension sensor. The utility model can store and release the film material according to the tension of the film material, eliminate the influence of the change of the unwinding speed on the coating production, and improve the stability of the coating quality;

[0005] However, combining the existing technology and the actual application of the cloth storage device in the tape processing process, there are still certain drawbacks in the current storage mechanism, such as:

[0006] During the fabric conveying process, it is impossible to avoid the mutual adsorption caused by static electricity, and the static electricity will make the burrs in the cloth material and gauze fibers protrude, ultimately affecting the quality of tape production;

[0007] During the conveying process, it is necessary to lift and lower the upper roller to maintain the stable tension of the fabric. However, during the lifting and lowering process, the fabric may shift, resulting in wrinkles and making the fabric uneven. If these wrinkles are not processed, they will also affect the quality of the tape.

[0008] Therefore, we propose a fabric storage mechanism with automatic tension control to solve the problems mentioned above. Summary of the Invention

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0046] Please refer toFigures 1-11 , the present invention provides the following technical solutions:

[0047] A tension self - controlled fabric storage mechanism, comprising: a frame 1, a fixed mounting frame 2, a lower passing roller 3, a sleeve 4, a conductive column 5, a spring 6, a conductive chain 7, a width adjusting rod 8, a connecting frame 9, an extrusion fork head 10, a fixing plate 11, a first telescopic rod 12, a partition plate 13, a first spring 14, a chuck 15, a clamping plate 16, a driving lead screw 17, a driven lead screw 18, a transmission belt 19, a lifting mounting frame 20, an upper passing roller 21, a chute 22, a sliding frame 23, an extrusion roller 24, a sliding rod 25, a second spring 26, an adjusting nut 27, a thermostat 28, a heating tube 29, a baffle 30, a fixed gear 31, a second telescopic rod 32, a connecting plate 33, an inserting shaft 34, a connecting gear 35, a feeding roller 36 and a discharging roller 37;

[0048] Among them: as Figure 1 , Figure 2 , Figure 3 and Figure 4 In, feeding rollers 36 and discharging rollers 37 are arranged on the left and right sides of the frame 1. A lower passing roller 3 for fabric conveying is arranged at the inner bottom of the frame 1. An upper passing roller 21 which can be lifted is further arranged above the lower passing roller 3 inside the frame 1. Fixed mounting frames 2 are symmetrically installed at the inner bottom of the frame 1. The lower passing rollers 3 are installed in an equally - spaced array and roll on the top of the fixed mounting frames 2. An elastic - telescopic conductive mechanism is arranged at the bottom of the fixed mounting frame 2 for eliminating fabric static electricity. At the same time, an anti - deviation mechanism for limiting the fabric outside the lower passing roller 3 is installed inside the fixed mounting frame 2. An extrusion roller 24 for extruding the fabric outside the upper passing roller 21 is correspondingly arranged above the upper passing roller 21. The extrusion roller 24 flattens the fabric by heating based on a heating element arranged inside.

[0049] In a specific application scenario, the fabric can be stored by the fixed mounting frame 2 and the liftable upper passing roller 21, and the tension of the fabric is adjusted by the lifting of the upper passing roller 21 to ensure the stable conveying of the fabric. At the same time, the conductive mechanism is used for static electricity release to avoid fabric adhesion and attraction, prevent fabric deviation, ensure fabric flatness, which is beneficial to improving the processing efficiency of the tape and ensuring production quality.

[0050] Among them: as Figure 4 and Figure 5Among them, the bottom of the fixed mounting bracket 2 is fixedly installed between the bottom of the frame 1 through a telescopic member. The conductive mechanism is symmetrically installed on the bottom of the frame 1 from left to right. The conductive mechanism includes a sleeve 4 fixed above the bottom surface of the fixed mounting bracket 2 and a conductive column 5 installed inside the sleeve 4. The bottom end of the conductive column 5 is connected with a conductive chain 7 capable of being connected to the ground. An edge protrusion is integrally provided on the outer circumference of the middle part of the conductive column 5. The bottom of the edge protrusion is telescopically connected with the sleeve 4 through a spring 6 to ensure that the top surface of the conductive column 5 is always in contact with the bottom surface of the fixed mounting bracket 2.

[0051] In a specific application scenario, through the contact between the top end of the conductive column 5 and the bottom surface of the fixed mounting bracket 2, and the bottom end of the conductive chain 7 is connected to the ground, electrostatic discharge can be carried out. Moreover, the fixed mounting bracket 2 can be lifted and lowered on the frame 1 by means of telescopic rods, lifting frames, etc., which can assist in adjusting the height of the fixed mounting bracket 2 to adapt to different height obstructions of the subsequent working surfaces, so as to facilitate processing operations. The conductive column 5 can be telescoped inside the sleeve 4 through the spring 6, which can ensure that the top end of the conductive column 5 is always in contact with the bottom surface of the fixed mounting bracket 2 to ensure normal conductive use in the case of lifting or vibration of the fixed mounting bracket 2 during the working process.

[0052] Among them: such as Figure 1 and Figure 6 Among them, the anti-deviation mechanism includes a width adjustment rod 8 rotatably connected to the middle part inside the fixed mounting bracket 2 and a connecting frame 9 connected to the outside of the width adjustment rod 8. The top end of the connecting frame 9 is integrally fixed with a pressing fork head 10 in a "Y" shape structure. The top of the pressing fork head 10 is correspondingly in contact with the outside of the lower roller 3. The width adjustment rod 8 drives the connecting frame 9 to slide towards or away from each other through the opposite thread screwing-in structures at both ends.

[0053] In a specific application scenario, a driving motor is arranged at the end of the width adjustment rod 8 close to the outer wall of the frame 1. The driving motor is connected to the width adjustment rod 8 through an electromagnetic brake. By rotating the width adjustment rod 8, the connecting frame 9 can be driven to slide inside the fixed mounting bracket 2 by using the opposite thread structures at both ends of the width adjustment rod 8, so that the connecting frame 9 drives the pressing fork head 10 to slide and adjust on the outside of the lower roller 3 to adjust the distance between the pressing fork heads 10 according to the width of the fabric, thereby facilitating the limitation of the fabric and preventing it from deviating.

[0054] Among them: such as Figure 6 and Figure 7In the embodiment, a first linkage member that can be separated and is located between the ends of adjacent width adjustment rods 8 is provided at the middle bottom of the frame 1. The first linkage member includes a first active end and a first driven end that are respectively installed at the ends of adjacent width adjustment rods 8. The first active end includes a fixed plate 11 fixed to the outside of the width adjustment rod 8. The outside of the fixed plate 11 is telescopically connected with a partition 13 through a first telescopic rod 12. The outside of the partition 13 is connected with a clamping head 15 through a first spring 14. The first driven end includes a clamping plate 16 fixed to the end of the adjacent width adjustment rod 8. The clamping head 15 is telescopically close to the clamping plate 16 through the first telescopic rod 12 to form a linkage with the corresponding clamping head.

[0055] In a specific application scenario, the adjacent width adjustment rods 8 can be transmitted through the linkage parts, so that the two sets of cloth storage mechanisms inside the frame 1 can be used for limit adjustment at the same time, which is convenient for processing and using the same product. The partition 13 and the clamping head 15 are pushed closer to the clamping plate 16 by the extension and retraction of the first telescopic rod 12, so that the clamping head 15 and the clamping plate 16 are engaged, which can enable the width adjustment rod 8 to be transmitted. When the width adjustment rod 8 is stuck or other unexpected situations occur, the elastic action of the first spring 14 will automatically squeeze and deflect the clamping head 15 outward, so that the clamping head 15 and the clamping plate 16 are disengaged to avoid damage to the equipment.

[0056] Among them: Figure 4 , Figure 10 and Figure 11 In the embodiment, a lifting and lowering mounting frame 20 is provided at the inner top of the frame 1, and upper rollers 21 are rotatably mounted at equal intervals at the bottom of the lifting and lowering mounting frame 20, and the two sides of the top of the lifting and lowering mounting frame 20 are respectively vertically connected with a driving screw 17 and a driven screw 18 rotatably mounted inside the frame 1, and the tops of the driving screw 17 and the driven screw 18 are connected by a transmission belt 19, and a second linkage member that can be separated and located between the ends of adjacent driven screws 18 is provided at the top of the frame 1, and the second linkage member includes a second driving end and a second driven end respectively mounted on the ends of adjacent driven screws 18;

[0057] The second active end includes a second telescopic rod 32 located on the outside of the driven screw rod 18 and with the bottom embedded in the top of the frame 1. The top of the second telescopic rod 32 is fixedly connected to a connecting plate 33. The connecting plate 33 is internally rotatably connected to a plug shaft 34 that is plugged into the top of the driven screw rod 18. The top of the plug shaft 34 is integrally provided with a connecting gear 35. The cross-sectional shape of the plug shaft 34 is a polygonal structure. The second driven end includes a fixed gear 31 fixed to the end of the adjacent driven screw rod 18. The tooth end faces of the fixed gear 31 and the connecting gear 35 on the outer sides opposite to each other are chamfered. The connecting gear 35 is telescoped close to the fixed gear 31 through the second telescopic rod 32 and meshes with it to form a linkage.

[0058] In a specific application scenario, a driving motor is provided at the end of the active lead screw 17 close to the outer wall of the frame 1. The driving motor is connected to the active lead screw 17 through an electromagnetic brake. The rotation of the driven lead screw 18 drives the driven lead screw 18 to rotate by means of the transmission belt 19, so as to lift and use the lifting mounting frame 20, thereby adjusting the height of the upper roller 21 for feeding and tension adjustment of the fabric. The adjacent driven lead screws 18 are driven by the second linkage member, which is convenient for adjusting the height of the two side lifting mounting frames 20 for feeding the same product during processing. Through the telescopic movement of the second telescopic rod 32, the connecting plate 33 can be driven to lift. When the connecting plate 33 descends, the insertion shaft 34 descends synchronously, so that the connecting gear 35 at the top of the insertion shaft 34 gradually meshes with the fixed gear 31. Since the tooth end faces of the opposite outer sides of the fixed gear 31 and the connecting gear 35 are chamfered, it can avoid collision when they approach. And through the insertion connection between the insertion shaft 34 and the driven lead screw 18, using its polygonal structure, it is convenient for transmission, so as to adjust the height of the two groups of lifting mounting frames 20 for use.

[0059] Among them: as Figure 3 , Figure 4 , Figure 8 and Figure 9 In, a chute 22 is provided on the side of the lifting mounting frame 20. A sliding frame 23 is slidably connected up and down inside the chute 22. An extrusion roller 24 is rotatably mounted at the bottom of the sliding frame 23. The extrusion roller 24 is vertically aligned with the upper roller 21. A heating element composed of a thermostat 28 and a heating tube 29 is installed on the outer side of the sliding frame 23. The thermostat 28 is fixedly installed on the top of the sliding frame 23. The heating tube 29 is inserted into the inside of the extrusion roller 24. Slide rods 25 are symmetrically fixed to the top of the sliding frame 23 and slidably penetrate through the bottom surface of the lifting mounting frame 20. A height-adjusting nut 27 for adjusting the lowest sliding height of the sliding frame 23 is threadedly connected to the top end of the slide rod 25. A second spring 26 is sleeved on the outer side of the slide rod 25 and is located between the lifting mounting frame 20 and the sliding frame 23.

[0060] In a specific application scenario, the slide 23 is connected to the lifting mounting frame 20 through the second spring 26, and the slide 23 forms a sliding structure with the lifting mounting frame 20 through the slide groove 22, so that the slide 23 can automatically slide on the inner bottom of the lifting mounting frame 20, so that the squeezing roller 24 at the bottom of the slide 23 automatically fits between the upper roller 21, and the cloth wrapped around the outer side of the upper roller 21 can be squeezed and flattened, and the lower limit of the slide 23 can be adjusted by screwing the height adjustment nut 27 on the top of the slide rod 25. The lowest height position of the slide 23 is lowered, so as to avoid excessive squeezing force of the squeezing roller 24 on the cloth, which affects the tension adjustment, and the heating tube 29 is heated by the temperature controller 28, so as to heat the squeezing roller 24 in the middle, so as to iron the burrs on the surface of the cloth and improve the quality of the tape product. At the same time, the outer side surface of the slide 23 protrudes from the outside of the lifting mounting frame 20. When the lifting mounting frame 20 descends, the outer bottom surface of the slide 23 contacts the top surface of the baffle 30, which can prevent the slide 23 from continuing to slide down, so as to facilitate the feeding of the cloth.

[0061] Example 1: When storing and loading two different cloth base materials, please refer to Figures 1-11 The present invention provides the following technical solutions: a tension-controlled cloth storage mechanism, when in use, firstly, the driving motors installed on both sides of the top of the frame 1 are respectively started to drive the active screws 17 of the two cloth storage mechanisms to rotate, and the active screw 17 is transmitted between the transmission belt 19 and the driven screw 18, so that the driven screw 18 is driven to rotate by the active screw 17, and then the lifting and lowering mounting frame 20 is lifted and lowered. After the lifting and lowering mounting frame 20 is lowered to the bottom, the side of the slide 23 slidably connected inside the lifting and lowering mounting frame 20 is in direct contact with the baffle 30 fixed to the frame 1 on the outside of the fixed mounting frame 2, so that the slide 23 stops descending, and after the lifting and lowering mounting frame 20 continues to descend, the upper surface of the upper roller 21 is located between the lower surface of the lower roller 3, and the cloth is threaded and loaded through the channel between the lower roller 3 and the upper roller 21;

[0062] After the loading is completed, the active screw rod 17 and the driven screw rod 18 are reversed to adjust the height of the lifting mounting frame 20 and the upper roller 21. The lifting mounting frame 20 is raised and lowered according to the tension of the fabric to keep the tension of the fabric stable. After the lifting mounting frame 20 rises, the slide 23 automatically slides down under the elastic action of the second spring 26, so that the squeezing roller 24 at the bottom of the slide 23 is close to the upper roller 21, so that the squeezing roller 24 squeezes the fabric on the surface of the upper roller 21 to make the fabric flat. At the same time, the heating temperature of the heating tube 29 is controlled by the thermostat 28 to heat the squeezing roller 24 in the middle, so that the fabric is ironed, and the wrinkles and burrs on the surface of the fabric can be ironed flat to improve the quality of the finished product.

[0063] Among them, the bottom surface of the fixed mounting bracket 2 is in contact with the conductive column 5, and the bottom end of the conductive column 5 is connected to the ground through a conductive chain 7, enabling conduction to facilitate static elimination and reducing the generation of fuzz on the fabric.

[0064] Embodiment 2: Different from the above embodiment, this embodiment enables the same type of fabric to be stored and fed. In order to synchronize the operation of the two fabric storage mechanisms on both sides inside the frame 1;

[0065] First, use the telescopic movement of the first telescopic rod 12 to push the partition 13 and the chuck 15 closer to the clamping plate 16, so that the chuck 15 is clamped with the clamping plate 16;

[0066] Then, through the telescopic movement of the second telescopic rod 32, drive the connecting plate 33 to rise and fall. When the connecting plate 33 descends, the insertion shaft 34 descends synchronously, so that the connecting gear 35 at the top of the insertion shaft 34 gradually meshes with the fixed gear 31;

[0067] The width adjustment rods 8 of the two fabric storage mechanisms can be linked. By rotating the active lead screw 17 on one side, the two lifting mounting brackets 20 can be driven to lift simultaneously, facilitating the storage and feeding of the same type of fabric base material.
