Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, and in particular relates to a foil cleaning device for sintered foil production. Background Technology

[0002] Currently, the main processes for producing sintered foil include foil cleaning, slurry forming, slurry compaction, and sintering. In existing technologies, when cleaning the foil, sometimes an unwinding mechanism is set up to unwind the foil, and another winding mechanism is set up opposite to the unwinding mechanism to wind the foil. The cleaning mechanism is set up in the foil conveying direction.

[0003] However, with the above setup, the distance between the foil and the liquid outlet of the cleaning mechanism will change during the foil conveying process. For example, before conveying, there are more foils on the unwinding mechanism than on the winding mechanism. At this time, the foils located between the unwinding and winding mechanisms are distributed at an angle, and the higher side of the foils is closer to the unwinding mechanism. As the foils are continuously conveyed and cleaned, the angle of inclination of the foils will change when the foils on the unwinding mechanism are continuously transferred to the winding mechanism, which will cause the distance between the foils and the liquid outlet of the cleaning mechanism to change. In order to ensure the cleaning effect, the position of the liquid outlet of the cleaning mechanism needs to be constantly adjusted, which is inconvenient. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a foil cleaning device for sintered foil production, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A foil cleaning device for sintered foil production includes foil and a worktable. A winding mechanism for winding and unwinding the foil is installed on the worktable. The winding mechanism includes a winding shaft and an unwinding shaft that are horizontally opposite to each other and can rotate synchronously in opposite directions. The winding shaft is located above the unwinding shaft, and a drive mechanism is connected to the winding shaft.

[0007] On the workbench located on one side of the winding mechanism, two supports are installed in sequence. The two supports are vertically opposite to each other and spaced apart. Each support has two guide rollers that are rotatably connected from top to bottom and are parallel to the take-up or unwinding shaft. A drying mechanism is installed between the tops of the two supports, and an acid washing mechanism is installed between the bottoms of the two supports. A water washing mechanism is also installed on the support located away from the winding mechanism. The end of the foil away from the unwinding shaft passes around the four guide rollers in sequence and is wound onto the take-up shaft. The foil passes through the acid washing mechanism, the water washing mechanism and the drying mechanism in sequence.

[0008] Furthermore, the pickling mechanism includes two first diversion boxes symmetrically arranged on both sides of the foil. Each first diversion box is connected to a support on both sides via a first connecting rod. Each first diversion box is connected to several first spray nozzles on the side closest to the foil. A second diversion box located outside the foil is also connected between the two first diversion boxes. A first infusion pump is connected to the second diversion box via a first infusion pipe. The first infusion pump is connected to an pickling tank installed in the workbench.

[0009] Furthermore, the washing mechanism includes two third diversion boxes symmetrically arranged on both sides of the foil. Both third diversion boxes are connected to the support, and each third diversion box is connected to several second spray nozzles on the side near the foil. A second infusion pipe located outside the support is also connected between the two third diversion boxes, and a second infusion pump is connected to one of the third diversion boxes through the third infusion pipe. A water tank installed in the workbench is connected to the second infusion pump.

[0010] Furthermore, a support plate is installed between the tops of the two supports, located below the foil. There are two sets of drying mechanisms, which are located on both sides of the foil and staggered. The drying mechanism located above the foil is located near the washing mechanism. Each set of drying mechanisms includes a fourth diversion box, which is connected to the support plate. Several drying nozzles are connected to the side of the fourth diversion box near the foil. A hot air blower is also connected to each fourth diversion box.

[0011] Furthermore, the winding mechanism also includes an inverted U-shaped support base. The take-up shaft and the unwind shaft are both located inside the inverted U-shaped support base and are rotatably connected to the inverted U-shaped support base. One end of the take-up shaft and the unwind shaft pass through the inverted U-shaped support base and are connected by gear transmission. The take-up shaft and the drive mechanism are connected by a chain transmission mechanism.

[0012] Furthermore, the take-up shaft includes two horizontally opposite first rotating shafts, one end of which is rotatably connected to an inverted U-shaped support base. A second rotating shaft is coaxially arranged between the two first rotating shafts. A horizontally slidable connecting sleeve is provided between both ends of the second rotating shaft and the first rotating shaft. The two ends of the connecting sleeve are connected to the first rotating shaft and the second rotating shaft respectively by bolt connections. The unwinding shaft has the same structure as the take-up shaft.

[0013] Furthermore, the workbench is equipped with horizontally distributed U-shaped baffles. The U-shaped openings of the U-shaped baffles are far away from the winding mechanism, and the U-shaped baffles are located on the side of the winding mechanism closer to the support. A U-shaped guide plate is installed on the workbench on the opening side of the U-shaped baffles. The U-shaped openings of the U-shaped guide plate face upwards, and a waste liquid collection box is provided below the U-shaped guide plate.

[0014] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0015] In use, this invention features a winding and unwinding shaft that rotate synchronously in opposite directions. When the foil is being wound up, it can be unwound simultaneously for easy transport. Four guide rollers guide the foil during transport, ensuring the foil remains angularly aligned between the rollers. Furthermore, the inclusion of an acid-washing mechanism, a water-washing mechanism, and a drying mechanism sequentially performs these processes to complete the cleaning. The arrangement of these mechanisms ensures that the distances between the foil and the outlets of the acid-washing, water-washing, and drying mechanisms remain constant, thus facilitating foil cleaning compared to existing technologies.

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, this utility model provides a foil cleaning device for sintered foil production, including a foil 14 and a worktable 8. The foil 14 is a prior art material, and the foil 14 is usually a rolled structure with a central through hole. A winding mechanism 3 for winding and unwinding the foil 14 is installed on the worktable 8. The winding mechanism 3 includes a winding shaft 31 and an unwinding shaft 32 that are horizontally opposite to each other and can rotate synchronously in opposite directions. The winding shaft 31 is located above the unwinding shaft 32, and a drive mechanism 12 is driven to the winding shaft 31. The drive mechanism 12 can drive the winding shaft 31 to rotate. In use, the rolled foil 14 is sleeved and fixed on the unwinding shaft 32 in the same way as in the prior art. Since the winding shaft 31 and the unwinding shaft 32 can rotate synchronously in opposite directions, the foil 14 can be unwound synchronously when it is being wound up, so as to facilitate the conveying of the foil 14.

[0024] On the workbench 8 located on one side of the winding mechanism 3, two supports 1 are sequentially installed. The two supports 1 are vertically opposite each other and spaced apart. Each support 1 has two guide rollers 2 rotatably connected from top to bottom, which are parallel to the take-up shaft 31 or the unwind shaft 32. The four guide rollers 2 are positioned opposite each other. A drying mechanism 6 is installed between the tops of the two supports 1, and an acid washing mechanism 4 is installed between the bottoms of the two supports 1. A washing mechanism 5 is also installed on the support 1 located away from the winding mechanism 3. The end of the foil 14 away from the unwind shaft 32 passes around the four guide rollers 2 in sequence and is then wound onto the take-up shaft 31. Specifically, the specific manner in which the foil 14 passes around the four guide rollers 2 is as follows: Figure 1 As shown, this allows the foil 14 to be guided during the conveying process, while the foil 14 located between the guide rollers 2 will not change in angle.

[0025] Furthermore, the foil 14 passes sequentially through the pickling mechanism 4, the washing mechanism 5, and the drying mechanism 6. In this way, during use, the foil 14 can be pickled, washed, and dried in sequence to complete the cleaning process of the foil 14. Moreover, the positional distribution of the pickling mechanism 4, the washing mechanism 5, and the drying mechanism 6 does not change the distance between the foil 14 and the liquid outlet of the pickling mechanism 4, the liquid outlet of the washing mechanism 5, and the air outlet of the drying mechanism 6. Therefore, compared with the prior art, it is easier to clean the foil 14.

[0026] The specific setup of pickling mechanism 4 is as follows: Figure 1 and Figure 2As shown, the pickling mechanism 4 includes two first diversion boxes 41 symmetrically arranged on both sides of the foil 14, so as to... Figure 1 For example, one first diversion box 41 is located above the foil 14 and parallel to the foil 14, and the other first diversion box 41 is located below the foil 14 and parallel to the foil 14. The two first diversion boxes 41 are arranged between two guide rollers 2 located at the bottom of the support 1. Both sides of each first diversion box 41 are connected to the support 1 through a first connecting rod 42. Each first diversion box 41 has several first spray nozzles 43 connected to the side of the first diversion box 41 closest to the foil 14. The side of the first spray nozzle 43 away from the first diversion box 41 is the liquid outlet. The spray range of the liquid nozzle 43 can cover the width of the foil 14; a second diversion box 44 located outside the foil 14 is also connected between the two first diversion boxes 41, so that the second diversion box 44 does not affect the conveying of the foil 14; a first infusion pump 46 is connected to the second diversion box 44 through a first infusion pipe 45, and an acid pickling tank 47 installed in the workbench 8 is connected to the first infusion pump 46. The acid pickling tank 47 contains acid pickling solution. When in use, after the first infusion pump 46 is started, acid pickling operations can be performed on both sides of the foil 14 simultaneously through the first spray nozzle 43.

[0027] The specific configuration of the water washing mechanism 5 is as follows: Figure 1 and Figure 3 As shown, the washing mechanism 5 includes two third diversion boxes 51 symmetrically arranged on both sides of the foil 14. Both third diversion boxes 51 are connected to the support 1. Specifically, one third diversion box 51 is directly connected to the support 1, and the other third diversion box 51 is connected to the support 1 through a second connecting rod 52. Furthermore, with... Figure 1 For example, one third diversion box 51 is located on the right side of the foil 14 and parallel to the foil 14, and the other third diversion box 51 is located on the left side of the foil 14 and parallel to the foil 14. The two third diversion boxes 51 are arranged between two guide rollers 2 located away from the winding mechanism 3. Each third diversion box 51 is connected to several second spray nozzles 53 on the side near the foil 14. The side of the second spray nozzles 53 away from the third diversion box 51 is the liquid outlet, and the spray range of the several second spray nozzles 53 can cover the width of the foil 14. In addition, the third diversion box 51 is equipped with... Multiple second spray nozzles 53 can be installed at the top to completely clean the pickling solution on the foil 14; a second infusion pipe 54 located outside the support 1 is also connected between the two third diversion boxes 51, so that the second infusion pipe 54 does not affect the delivery of the foil 14; and a second infusion pump 56 is connected to one of the third diversion boxes 51 through a third infusion pipe 55. The second infusion pump 56 is connected to a water tank 57 installed in the workbench 8. Specifically, when the second infusion pump 56 is started, the foil 14 can be washed simultaneously on both sides through the second spray nozzles 53.

[0028] The specific configuration of the drying mechanism 6 is as follows: Figure 1 and Figure 4 As shown, a support plate 11 is installed between the tops of the two supports 1, located below the foil 14. There are two sets of drying mechanisms 6, located on both sides of the foil 14 and staggered, to... Figure 1 For example, one set of drying mechanisms 6 is located above the foil 14, and the other set of drying mechanisms 6 is located below the foil 14. The two sets of drying mechanisms 6 are arranged between the two guide rollers 2 located at the top of the support 1. The drying mechanism 6 located above the foil 14 is arranged close to the washing mechanism 5, so that the top surface of the foil 14 can be dried first. Each set of drying mechanisms 6 includes a fourth diversion box 61, and the fourth diversion box 61 is connected to the support plate 11. Specifically, one fourth diversion box 61 is directly installed on the support plate 11, and the other fourth diversion box 61 is connected to the support plate 11. The support plates 11 are connected by pillars 64. In use, the foil 14 passes through the four pillars 64. Several drying nozzles 62 are connected to the side of the fourth distribution box 61 near the foil 14. The side of the drying nozzles 62 away from the fourth distribution box 61 is the air outlet. The spray range of the several drying nozzles 62 can cover the width of the foil 14. A hot air blower 63 is also connected to each fourth distribution box 61. Specifically, in use, when the hot air blower 63 is started, both sides of the foil 14 can be dried simultaneously through the drying nozzles 62.

[0029] The specific arrangement for the take-up shaft 31 and the unwind shaft 32 to rotate synchronously in opposite directions is as follows: Figure 1 As shown, the winding mechanism 3 also includes an inverted U-shaped support base 33. The take-up shaft 31 and the unwind shaft 32 are both located inside the inverted U-shaped support base 33 and are rotatably connected to the inverted U-shaped support base 33. One end of the take-up shaft 31 and the unwind shaft 32 passes through the inverted U-shaped support base 33 and is connected by two meshing gears 34. The take-up shaft 31 is connected to the drive mechanism 12 by a chain drive mechanism 13. Specifically, the drive mechanism 12 can be configured as a drive motor with a reducer. By setting the chain drive mechanism 13, slippage will not occur.

[0030] Furthermore, such as Figure 5As shown, the take-up shaft 31 includes two horizontally opposite first rotating shafts 311. One end of each first rotating shaft 311 is rotatably connected to an inverted U-shaped support 33. A second rotating shaft 312 is coaxially arranged between the two first rotating shafts 311. Both ends of the second rotating shaft 312 are provided with horizontally sliding connecting sleeves 313 between them and the first rotating shafts 311. The two ends of the connecting sleeves 313 are connected to the first rotating shafts 311 and the second rotating shafts 312 respectively by bolt connections. Specifically, the bolt connection includes a connecting bolt and a locking nut. In use, the threaded end of the connecting bolt passes through the connecting sleeve 313, the first rotating shaft 311 or the second rotating shaft 312 in sequence and then the locking nut is fitted on it. This facilitates the installation and removal of the second rotating shaft 312 between the two first rotating shafts 311, thereby facilitating the removal of the foil 14 after winding. Secondly, the unwinding shaft 32 has the same structure as the take-up shaft 31, which facilitates the mounting and fixing of the rolled foil 14 onto the unwinding shaft 32.

[0031] Furthermore, such as Figure 1 As shown, horizontally distributed U-shaped baffles 7 are installed on the workbench 8. The U-shaped opening of the U-shaped baffles 7 is away from the roller mechanism 3, and the U-shaped baffles 7 are located on the side of the roller mechanism 3 closer to the support 1, so that the pickling liquid and water will not flow to the roller mechanism 3. A U-shaped guide plate 9 is installed on the open side of the U-shaped baffles 7 on the workbench 8. The U-shaped opening of the guide plate 9 faces upward, and a waste liquid collection tank 10 is installed below the guide plate 9. Specifically, during use, the sprayed pickling liquid and water can fall onto the workbench 8 located inside the U-shaped baffles 7, and then the pickling liquid and water can fall into the waste liquid collection tank 10 through the U-shaped guide plate 9 to facilitate the recovery of pickling liquid and water.
