Description

Technical Field

[0001] The utility model relates to the technical field of spray booths in painting lines, and particularly relates to a paper tape regeneration device. Background Art

[0002] In the pretreatment process of the surface treatment industry, phosphating or silane reaction is mostly required to form a phosphating film or a silane film on the surface of workpieces to provide the bonding force for subsequent treatment. During the phosphating or silane reaction, phosphating slag or silane slag will be generated in the treatment liquid. In order to avoid the accumulation of these phosphating slag or silane slag, which may cause pollution to the workpieces, slag removal equipment needs to be equipped to remove the phosphating slag or silane slag from the treatment liquid.

[0003] The paper tape filter is a common equipment for removing phosphating slag or silane slag. After the paper tape is used, phosphating slag or silane slag will adhere to the surface and in the shallow layer. If it is used for the second time, it will cause problems such as large system resistance and poor effect, and even failure. Therefore, it is necessary to clean the paper tape or directly replace it.

[0004] Due to the large volume and heavy weight of the paper tape, it is inconvenient to clean manually. Therefore, in the prior art, the paper tapes of each production enterprise can usually only be used 1 - 2 times and then need to be replaced. As a result, the replacement frequency of the paper tape is high and the cost is very high. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a paper tape regeneration device with strong cleaning ability, good effect, cost saving and compact structure, which can realize the recycling of paper tapes.

[0006] The utility model is realized by the following technical solutions: A paper tape regeneration device includes an unwinding device, a paper tape, a backwashing nozzle, a guiding roller group, a water tank, a forward washing nozzle, a water squeezing roller group, a drying device and a winding device. One end of the paper tape is wound around the unwinding device, and the other end is wound around the winding device and is tensioned by the guiding roller group. The unwinding device and the winding device can rotate around their respective rotating shafts, so as to drive the paper tape to move from the unwinding device to the winding device, thereby realizing the flow of the paper tape.

[0007] The water tank is mainly used for storing and providing cleaning liquid for the cleaning device. Since phosphating slag or silane slag is insoluble in the cleaning liquid and can settle naturally, in order to realize the recycling of the cleaning liquid in the water tank, further, a flow guiding plate and a dirt retaining plate are arranged in the water tank. The flow guiding plate is connected to the side wall of the water tank and extends obliquely into the water tank, and the dirt retaining plate is vertically arranged on the bottom surface of the water tank. The flow guiding plate and the dirt retaining plate divide the water tank into a sedimentation chamber and a reflux chamber, and the bottom surface of the water tank slopes downward towards the sedimentation chamber.

[0008] Further, a first valve, a filter, a pump, a second valve, and a check valve are successively provided on the path of the return chamber of the water tank to supply water to the following backwash nozzles and forward flush nozzles. The above-mentioned water source generally refers to a cleaning liquid. The bottom of the sedimentation chamber of the water tank leads to a wastewater treatment device and is provided with a third valve, thereby forming the supply of the cleaning liquid and the treatment of the waste liquid.

[0009] Further, the guide roller group includes two guide rollers that are horizontally arranged and spaced apart by a certain distance, and the two guide rollers are immersed in the upper part of the sedimentation chamber of the water tank.

[0010] To ensure the best cleaning effect of the paper tape, the paper tape regeneration device is designed with multiple cleaning links. Specifically, the backwash nozzles are arranged on the path between the unwinding device and the guide roller group and are located inside the paper tape, and the forward flush nozzles are arranged on the path between the guide roller group and the winding device and are located outside the paper tape. The return chamber of the water tank is communicated with the backwash nozzles and the forward flush nozzles and supplies cleaning liquid to the backwash nozzles and the forward flush nozzles.

[0011] To further improve the cleaning effect of the paper tape, the paper tape regeneration device further includes a soft hair roller. The surface of the soft hair roller is attached with cleaning soft hairs. The soft hair roller is arranged in the water tank and on the path between the two guide rollers. The soft hair roller abuts against the paper tape and can rotate around its own rotating shaft, thereby acting on the surface of the paper tape to realize the brushing of the surface or the shallow layer of the paper tape.

[0012] To realize the drying of the paper tape after cleaning, the water squeezing roller group is arranged between the forward flush nozzles and the winding device and is clamped on the paper tape, and the air drying device is arranged on the path between the water squeezing roller group and the winding device.

[0013] Further, to improve the drying effect, the air drying device includes a plurality of air drying nozzles that are equidistantly arranged on the path between the water squeezing roller group and the winding device.

[0014] The beneficial effects of the present utility model are as follows: The paper tape regeneration device, by designing a paper bag cleaning and drying device including backwash nozzles, soft hair rollers, forward flush nozzles, water squeezing roller groups, and air drying devices, and cooperating with a paper tape transmission device composed of an unwinding device, a guide roller group, and a winding device, realizes the cleaning and drying of the paper tape, thereby improving the utilization rate of the paper tape, saving costs, and improving environmental protection; by optimizing the design of the paper bag cleaning device and the drying device, the cleaning effect and drying efficiency of the paper tape are improved; in addition, the paper tape regeneration device has a compact structure and can be recycled.

[0018] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0019] As Figure 1 shown, a paper tape regeneration device includes an unwinding device 1, a paper tape 2, a backwashing nozzle 3, a guide roller group 4, a soft hair roller 5, a water tank 6, a forward flushing nozzle 7, a water squeezing roller group 8, a drying device 9 and a rewinding device 10. One end of the paper tape 2 is wound around the unwinding device 1, and the other end is wound around the rewinding device 10 and is tensioned by the guide roller group 4. The unwinding device 1 and the rewinding device 10 can rotate around their respective rotating shafts, thereby driving the paper tape 2 to be transmitted from the unwinding device 1 to the rewinding device 10.

[0020] The water tank 6 is provided with a flow guiding plate 61 and a dirt blocking plate 62. The flow guiding plate 61 is connected to the side wall of the water tank 6 and extends obliquely into the water tank 6. The dirt blocking plate 62 is vertically arranged on the bottom surface of the water tank 6. The flow guiding plate 61 and the dirt blocking plate 62 divide the water tank 6 into a settling chamber 63 and a return chamber 64. The bottom surface of the water tank 6 slopes downward towards the settling chamber 63. The return chamber 64 of the water tank 6 is communicated with the backwashing nozzle 3 and the forward flushing nozzle 7 and provides cleaning liquid for the backwashing nozzle 3 and the forward flushing nozzle 7.

[0021] As Figure 2 shown, a first valve 11, a filter 12, a pump 13, a second valve 14 and a check valve 15 are sequentially arranged on the path where the return chamber 64 of the water tank 6 provides cleaning liquid for the backwashing nozzle 3 and the forward flushing nozzle 7. The bottom of the settling chamber 63 of the water tank 6 leads to a wastewater treatment device and is provided with a third valve 16.

[0022] The guide roller group 4 includes two guide rollers 41 that are horizontally arranged and spaced apart by a certain distance. The two guide rollers 41 are immersed in the upper part of the settling chamber 63 of the water tank 6.

[0023] The backwashing nozzle 3 is arranged on the path between the unwinding device 1 and the guide roller group 4 and is located inside the paper tape 2, the forward flushing nozzle 7 is arranged on the path between the guide roller group 4 and the winding device 10 and is located outside the paper tape 2, the soft hair roller 5 is arranged inside the water tank 6 and on the path between the two guide rollers 41, the soft hair roller 5 abuts against the paper tape 2 and can rotate around its own rotating shaft, so as to act on the surface of the paper tape 2, the water squeezing roller group 8 is arranged between the forward flushing nozzle 7 and the winding device 10 and clamps the paper tape 2, and the drying device 9 is arranged on the path between the water squeezing roller group 8 and the winding device 10. The drying device 9 includes a plurality of drying air nozzles arranged at equal intervals along the path between the water squeezing roller group 8 and the winding device 10.

[0024] The process of realizing the cleaning and recycling of the paper tape by using this paper tape recycling device is as follows: Install the used paper tape roll in the paper tape filter on the unwinding device 1. The outer end of the paper tape 2 passes through two guide rollers 41 and the water squeezing roller group 8 in sequence, and finally winds around the winding device 10 and is tensioned by the guide roller group 4. Start the equipment, and the unwinding device 1 and the winding device 10 rotate around their respective rotating shafts, driving the paper tape 2 to gradually move from the unwinding device 1 to the winding device 10. On the moving path of the paper tape 2, first, the backwashing nozzle 3 backwashes the paper tape 2 from the side without phosphating slag or silane slag, and can wash out the phosphating slag or silane slag entering the gap inside the paper tape 2. Most of the phosphating slag or silane slag attached to the surface of the paper tape 2 will be washed off during backwashing. Then, the soft hair roller 5 in the water tank 6 further frictionally brushes the surface and the shallow layer of the paper tape 2. After being frictionally brushed by the soft hair roller 5, the paper tape 2 leaves the water tank 6, and the forward flushing nozzle 7 performs the last forward flushing on the paper tape 2 to achieve the effect of thorough cleaning. Finally, the cleaned paper tape 2 is dried after passing through the water squeezing roller group 8 and the drying device 9 in sequence, and enters the winding device 10 for winding, thus completing the cleaning and recycling of the paper tape 2.

[0025] During the cleaning process, since a flow guide plate 61 and a dirt retaining plate 62 are arranged in the water tank 6, the liquid containing more phosphating slag or silane slag enters the sedimentation chamber 63, and the clear liquid enters the reflux chamber 64. The clear liquid entering the reflux chamber 64 is pressurized and circulated by the pump 13 and sent to the backwashing nozzle 3 and the forward flushing nozzle 7, and the cleaning liquid can be recycled, reducing the use cost of the equipment.
