Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tape production technology, and more specifically, it relates to an integrated coating and drying device. Background Technology
[0002] In the production of adhesive tape, a necessary step is coating. This involves applying adhesive to the pre-made tape, drying the coated tape, and finally rolling it into rolls for storage. Generally, this is done by pouring adhesive into a glue tank and then passing the tape through the tank for coating. However, this coating method has the following disadvantages:
[0003] 1. Because adhesive residue adheres to the bottom of the tape, it will drip onto the drying equipment or the ground during the subsequent drying process, and will be difficult to clean after it solidifies.
[0004] 2. As the adhesive continuously adheres to the tape, the adhesive content in the glue tank decreases, requiring frequent refilling of the glue tank to maintain continuous tape coating. Furthermore, as the adhesive in the glue tank decreases, the adhesion of the adhesive to the tape also changes, affecting the quality of the finished tape. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a coating and drying integrated device to solve the problem that the adhesive drippings from existing coating and drying integrated machines are difficult to clean.
[0006] This utility model provides an integrated coating and drying device, which is achieved by the following specific technical means:
[0007] A coating and drying integrated device includes a tension structure, a coating structure, a drying structure, a take-up and unwinding structure, and a frame. The frame includes a base plate, side plates fixedly connected to both sides of the base plate, a reinforcing plate fixedly connected in front between the side plates, and a top plate fixedly connected above between the side plates. The take-up and unwinding structure, tension structure, coating structure, drying structure, and take-up and unwinding structure are arranged sequentially from front to back between the side plates. The take-up and unwinding structure includes a geared motor, a pulley E fixedly connected to the shaft of the geared motor, a belt C wrapped around the pulley E, and belt C also wrapping around pulleys F and G. An unwinding roller is fixedly connected to one side of pulley F, and a take-up roller is fixedly connected to one side of pulley G.
[0008] Furthermore, the unwinding roller and the winding roller are connected to the fixing groove at both ends by fastening bolts. A bearing is provided on the side of the fixing groove away from the unwinding roller and the winding roller, and the bearing is rotatably connected on the two side plates of the frame.
[0009] Furthermore, the tension structure includes hydraulic cylinder A and hydraulic cylinder B, with one set of hydraulic cylinder A and one set of hydraulic cylinder B fixedly connected to the outside of the frame side plate. Each set of hydraulic cylinder A has a connecting block on its telescopic rod, and two upper tension rollers are fixedly connected between the two sets of connecting blocks. The lower tension roller is rotatably connected between the ends of the telescopic rods of hydraulic cylinder B.
[0010] Furthermore, a pulley A is provided on one side of the lower tension roller, a belt A is wrapped around the pulley A, and the belt A also wraps around the pulley B. The pulley B is fixedly connected to the rotating shaft of the motor A. The bottom of the motor A is mounted on a movable motor base, and four limiting rods are inserted through the movable motor base to form a sliding connection in the vertical direction. The bottom of the limiting rods is fixed to the frame base plate.
[0011] Furthermore, the coating structure includes bearings, with four groups of bearings in pairs. Each group of two bearings is rotatably connected to the side plates on both sides of the frame. A coating roller is connected between each group of bearings. There are four coating rollers in total. Coating cloth is wound around the middle of the coating roller. A pulley C is set on one side of the coating roller. The pulley C is wrapped around the belt B. The belt B is also wrapped around the pulley D. The pulley D is fixed on the shaft of the motor B.
[0012] Furthermore, multiple coating tubes are arranged in an array above each coating roller, with the tube openings located directly above the coating cloth. Each coating tube is connected to an injection tube, and there are four sets of injection tubes. One side of the injection tube is connected to an infusion tube, and a constant pressure pump is installed on a branch of the infusion tube. The end of the infusion tube collection tube is connected to a storage tank.
[0013] Furthermore, the drying structure includes a drying plate with closely spaced heat-conducting pipes at the bottom of the drying plate. The two ends of the heat-conducting pipes are connected to heaters, and the heaters are fixed at both ends of the bottom of the drying plate.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model completes a series of steps such as feeding, coating, drying, and winding of the tape by setting up a tension structure, coating structure, drying structure, and winding structure. The integrated processing level is high, thereby reducing the connection time of each operation and greatly improving processing efficiency.
[0016] 2. This utility model, by setting a tension structure, allows the tape to pass between the upper tension roller and the lower tension roller. The height of the upper tension roller is adjusted by hydraulic cylinder A according to the tape material, and the height of the lower tension roller is adjusted by hydraulic cylinder B. The lower tension roller is rotated by motor A to provide pre-tightening force, so that the tape is in the most suitable tension state. This avoids the tape being too loose during coating, which reduces the adhesion of the adhesive, or the tape being too tight, which causes the tape to be stretched and affects the quality of the finished product.
[0017] 3. This utility model, by setting up a coating structure, drips the adhesive stored in the storage tank onto the coating cloth through the coating tube. Then, driven by motor B, the coating roller rotates, so that the adhesive on the coating cloth is coated onto the tape passing below the coating roller. The coating tubes are distributed in a crisscross pattern, which is conducive to uniform coating. In addition, the constant pressure pump makes the flow rate of the adhesive dripping from the coating tube uniform, thus controlling the quality of the finished tape. Attached Figure Description

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0029] Example:
[0030] As attached Figure 1 To be continued Figure 8 As shown:
[0031] This utility model provides an integrated coating and drying device, including a tension structure, a coating structure, a drying structure, a take-up and unwinding structure, and a frame. The frame includes a base plate 1, side plates 2 are fixedly connected to both sides of the base plate 1, a reinforcing plate 3 is fixedly connected between the side plates 2 at the front, and a top plate 4 is fixedly connected between the side plates 2 at the top. The take-up and unwinding structure, tension structure, coating structure, drying structure, and take-up and unwinding structure are arranged sequentially from front to back between the side plates 2. The take-up and unwinding structure includes a reduction motor 31, a pulley E32 is fixedly connected to the shaft of the reduction motor 31, a belt C33 is wrapped around the pulley E32, and the belt C33 also wraps around pulleys F34 and G38. An unwinding roller 35 is fixedly connected to one side of pulley F34, and a take-up roller 39 is fixedly connected to one side of pulley G38.
[0032] Among them, such as Figure 7 and Figure 8 As shown, the unwinding roller 35 and the take-up roller 39 are connected to the fixing groove 36 at both ends by fastening bolts 37. The fixing groove 36 is provided with a bearing 16 on the side away from the unwinding roller 35 and the take-up roller 39. The bearing 16 is rotatably connected to the side plates 2 on both sides of the frame. The fastening bolts 37 can be removed to release the fixed connection between the unwinding roller 35 or the take-up roller 39 and the fixing groove 36, thereby facilitating the feeding and unloading of the tape.
[0033] Among them, such as Figure 3As shown, the tension structure includes hydraulic cylinders A5 and B8. One set of hydraulic cylinders A5 and B8 are fixedly connected to the outside of the frame side plate 2. A connecting block 6 is installed on the telescopic rod of each set of hydraulic cylinders A5. Two upper tension rollers 7 are fixedly connected between the two sets of connecting blocks 6. A lower tension roller 9 is rotatably connected between the ends of the telescopic rods of hydraulic cylinders B8. A pulley A10 is installed on one side of the lower tension roller 9, and a belt A11 is wrapped around pulley A10. Belt A11 also wraps around pulley B12. Pulley B12 is fixedly connected to the shaft of motor A13. The bottom of motor A13 is mounted on a movable... Four limiting rods 15 are inserted into the base 14 and the movable motor base 14 to form a sliding connection in the vertical direction. The bottom of each limiting rod 15 is fixed to the frame base plate 1. The tape passes between the upper tension roller 7 and the lower tension roller 9. The height of the upper tension roller 7 is adjusted by the hydraulic cylinder A5 according to the tape material, and the height of the lower tension roller 9 is adjusted by the hydraulic cylinder B8. The lower tension roller 9 is rotated by the motor A13 to provide pre-tightening force, so that the tape is in the most suitable tension state. This avoids the tape being too loose during coating, which reduces the adhesion of the adhesive, or the tape being too tight, which stretches the tape and affects the quality of the finished product.
[0034] Among them, such as Figure 4 As shown, the coating structure includes bearings 16, arranged in pairs of four groups of two bearings 16. Each group of two bearings 16 is rotatably connected to the side plates 2 on both sides of the frame. Coating rollers 17 are connected between each group of bearings 16. There are four coating rollers 17 in total, with coating cloth 18 wound around the center of each roller 17. A pulley C19 is located on one side of each roller 17, and the pulley C19 is wrapped around a belt B20. A pulley D21 is also wrapped around the belt B20 and fixed to the shaft of a motor B22. Multiple coating tubes 23 are arranged in an array above each coating roller 17, with the openings of the coating tubes 23 located directly above the coating cloth 18. The upper part of each of the coating tubes 23 is connected to the injection tube 24. There are four sets of injection tubes 24. One side of the injection tube 24 is connected to the infusion tube 25. A constant pressure pump 26 is installed on a branch of the infusion tube 25. The end of the infusion tube 25 is connected to the storage tank 27. The coating tube 23 drips the adhesive stored in the storage tank 27 onto the coating cloth 18. Then, driven by the motor B22, the coating roller 17 rotates, so that the adhesive on the coating cloth 18 is coated onto the tape passing under the coating roller 17. The coating tubes 23 are crisscrossed to facilitate uniform coating. In addition, the constant pressure pump 26 makes the flow rate of the adhesive dripping from the coating tube 23 uniform, controlling the quality of the finished tape.
[0035] Among them, such as Figure 6As shown, the drying structure includes a drying plate 28, with closely spaced heat-conducting pipes 29 at the bottom of the drying plate 28. The two ends of the heat-conducting pipes 29 are connected to heaters 30, and the heaters 30 are fixed at both ends of the bottom of the drying plate 28. The drying plate 28 is relatively wide. The tape coated by the tape is controlled by the unwinding and winding structure controlled by the geared motor 31 to be laid on the top of the drying plate 28 and slowly passed through. The drying plate 28 is heated by the heaters 30 and by the heat conduction of the heat-conducting pipes 29, thereby drying the tape on the drying plate 28.
[0036] The specific usage and function of this embodiment are as follows:
[0037] In this invention, the pre-formed adhesive tape is fed onto the unwinding roller 35, passes above the two upper tension rollers 7 and below the lower tension roller 9 of the tension structure, then passes below the coating roller 17 of the coating structure, and then passes above the drying plate 28 of the bonding and drying structure. Finally, it is wound up and unloaded on the take-up roller 39. The reduction motor 31 is started to control the operation of the take-up and unwinding structure, and the adhesive tape begins to move forward on the integrated machine. The height of the upper tension roller 7 is adjusted by the hydraulic cylinder A5 according to the material of the adhesive tape, the height of the lower tension roller 9 is adjusted by the hydraulic cylinder B8, and the lower tension roller 9 is rotated by the motor A13 to provide pre-tension force, so that the adhesive tape is tightened and in the most suitable tension state. The constant pressure pump 26 controls the coating tube 23 to drip the adhesive liquid stored in the storage tank 27 into the coating cloth 1. 8. Then, driven by motor B22, the coating roller 17 rotates, so that the adhesive on the coating cloth 18 is applied to the tape passing under the coating roller 17. The coating tubes 23 are crisscrossed to facilitate uniform coating. In addition, the constant pressure pump 26 controls the flow rate of the adhesive dripping from the coating tubes 23 to be uniform, thus controlling the quality of the finished tape. The unwinding and winding structure controlled by the geared motor 31 controls the coated tape to be placed above the drying plate 28 and slowly pass through. The drying plate 28 is heated by the heater 30 and the heat conduction tube 29, thereby drying the tape on the drying plate 28. Finally, the coated and dried tape is wound up on the winding roller 39. After winding, the fastening bolt 37 is removed to disconnect the winding roller 39 from the fixing groove 36 for winding.
