Description

Technical Field

[0001] The utility model relates to the field of pole piece electroplating, and in particular to a composite material multi-stage electroplating device. Background Art

[0002] In the process of battery processing and production, it is necessary to process the coils of composite sheet materials such as metal foil, such as electroplating. Existing sheet processing usually adopts an automated processing method, which discharges the material through the coil, immerses the coil in the electroplating solution to form an electroplating layer, and then dries and collects the material through the coil. However, in the actual processing process, it is found that since the sheet is loaded in the form of coils, a new coil needs to be replaced every time a coil is processed. The newly replaced coil needs to be re-leaded out so that the sheet passes through each processing component in turn, which leads to slow processing connection speed and affects processing efficiency.

[0003] In addition, after electroplating, some electrolyte will adhere to the upper and lower surfaces of the sheet. If it is directly rolled up, the formed coil will become damp and affect the forming quality. Therefore, the sheet needs to be dried before rolling up. The existing drying method is usually to directly pass the sheet through an oven for drying. However, this method has low drying efficiency, and usually natural cooling is used for cooling. After cooling, it is rolled up, which further reduces the processing efficiency. Utility Model Content

[0048] Please refer to Figure 1 , Figure 2 , Figure 6 and Fig. 9 The present embodiment provides a composite material multi-stage electroplating equipment, comprising: an unwinding device 1, a plurality of electroplating devices 2, a drying device 3 and a winding device 4, wherein the unwinding device 1 is used to store the material roll and convey the sheet on the material roll, and comprises an unwinding seat 11, and an unwinding rack 12 slidably arranged on the unwinding seat 11, and a film connection component 16 is provided on the unwinding rack 12, and the film connection component 16 is used to connect the sheets of different material rolls; the plurality of electroplating devices 2 are arranged in sequence along the conveying direction of the sheet, and are used to electroplate the opposite sides of the sheet; the drying device 3 comprises a drying rack 31, and an oven 32, a hot air mechanism 33 and a cooling mechanism 34 sequentially installed on the drying rack 31 along the conveying direction of the sheet; the winding device 4 is used to recycle the electroplated sheet, and comprises a winding seat 41, and a winding rack 42 slidably arranged on the winding seat 41, and a film pressing component 43 is movably provided on the winding rack 42, and the film pressing component 43 is used to extrude the surface of the material roll.

[0049] In the present embodiment, when electroplating is performed, the coil is mounted on an unwinding rack 12. After the sheet is led out, it passes through a plurality of electroplating devices 2, drying devices 3 and winding devices 4 in sequence to achieve multiple electroplating thickening of the sheet, making the thickness of the conductive layer of the sheet more uniform. The sheet can also be dried and wound, thereby realizing automated electroplating operations of the coil.

[0050] Among them, the film splicing assembly 16 provided on the unwinding rack 12 can connect sheets of different rolls, effectively reducing the downtime during roll change and improving production efficiency. The oven 32, hot air mechanism 33 and cooling mechanism 34 on the drying rack 31 work in sequence to ensure that the sheets can be dried promptly and effectively after electroplating. The use of secondary drying can effectively improve the drying efficiency, and after drying, the cooling mechanism 34 can be used to quickly cool the sheets to meet the winding requirements, thereby further improving the processing efficiency. In addition, the film pressing assembly 43 provided on the winding rack 42 can extrude and shape the surface of the roll during the sheet winding process, making the roll more compact, thereby effectively improving the processing quality.

[0051] Therefore, the composite material multi-stage electroplating equipment of this embodiment can achieve uniform and sufficient electroplating treatment on both sides of the sheet through multiple electroplating, thereby ensuring the quality of electroplating; the film splicing component 16 allows for rapid film splicing when replacing the material roll to shorten downtime, and the drying mechanism ensures that the sheet can be quickly dried and cooled after electroplating for rapid reeling, thereby not only ensuring the quality of the electroplating process, but also effectively improving the efficiency of the electroplating process.

[0052] Please refer to Figure 2 In this embodiment, the unwinding frame 12 is provided with an unwinding shaft 13, an unwinding driving member 14, and a plurality of feeding roller shafts 15. The unwinding shaft 13 is rotatably mounted on the unwinding frame 12, the output end of the unwinding driving member 14 is connected to one end of the unwinding shaft 13, and the plurality of feeding roller shafts 15 are arranged on the unwinding frame 12 at intervals. Among them, the unwinding driving member 14 is a rotating driving member such as a motor or a rotating cylinder.

[0053] When the unwinding device 1 is unwinding, the sheet is placed on the unwinding shaft 13, so that the sheet passes through the film splicing assembly 16 and different feeding rollers 15 and then docks with the electroplating device 2, and then the unwinding drive 14 drives the unwinding shaft 13 to rotate to realize the automatic unwinding function. In addition, since the unwinding frame 12 is slidably arranged on the unwinding seat 11, the position of the unwinding frame 12 is adjustable, and the position of the unwinding frame 12 can be adjusted according to actual conditions to correct the deviation, thereby improving the flexibility of operation and facilitating the precise alignment of the sheet.

[0054] Please refer to Figure 3 The film splicing assembly 16 of this embodiment includes a film pad 161 and two sets of pressing units 162. The film pad 161 is mounted on the unwinding frame 12. The two sets of pressing units 162 are mounted on the film pad 161 and are spaced apart along the conveying direction of the sheet. A knife groove can be provided on the film pad 161. The knife groove is located between the two sets of pressing units 162. The knife groove allows the cutter 444 to pass through, so as to facilitate the cutting of the sheet.

[0055] When the film splicing assembly 16 is replacing the coil, the end of the old coil is pressed by the pressing unit 162 located at the rear end of the sheet conveying direction to stop it from being conveyed, and the front end of the new coil is pressed by the pressing unit 162 located at the front end of the sheet conveying direction. At this time, the overlapping part of the new coil and the old coil is cut by the cutter 444, and then the waste is removed. Then, the end of the old coil and the front end of the new coil are attached by tape to achieve the connection of the sheets. It should be noted that the processes of cutting and attaching tape can be operated manually.

[0056] Please continue to refer to Figure 3 Specifically, the sheet pressing unit 162 includes a sheet pressing driver 1621, a connection block 1622 and a film pressing plate 1623. The sheet pressing driver 1621 is mounted on the film pad 161, the film pressing plate 1623 can be placed on the film pad 161 in contact, and the connection block 1622 is used to connect the output end of the sheet pressing driver 1621 and the film pressing plate 1623. The sheet pressing driver 1621 is a cylinder, the sheet pressing driver 1621 is mounted on the lower surface of the film pad 161, the output shaft of the sheet pressing driver 1621 extends to the upper surface of the film pad 161, the film pressing plate 1623 can contact the upper surface of the film pad 161, and press the sheet material between the film pressing plate 1623 and the upper surface of the film pad 161.

[0057] The structural design of the tablet pressing unit 162 of this embodiment is compact and efficient. The tablet pressing drive 1621 is directly installed on the film pad 161, which ensures stability and saves space. The connecting block 1622 serves as a bridge between the tablet pressing drive 1621 and the pressing plate, ensuring efficient power transmission. At the same time, the structure is simple and convenient for installation and maintenance. The tablet pressing drive 1621 accurately controls the lifting action of the pressing plate through the connecting block 1622 to achieve accurate pressure on the new and old sheets. The contactable design of the pressing plate ensures that it can fit closely with the sheet when pressurizing, achieving a good film bonding effect.

[0058] In addition, the sheet pressing driving member 1621 and the connecting block 1622 are two groups arranged opposite to each other, which can respectively drive the two ends of the film pressing plate 1623 to move. The two groups of sheet pressing driving members 1621 and the connecting block 1622 are symmetrically arranged. This structural design ensures the stability and uniformity of the film pressing process, so that the pressure applied to the sheet is evenly distributed, avoiding the film connection quality problem caused by uneven pressure.

[0059] It should be noted that both ends of the film pad 161 are detachably mounted on the unwinding frame 12 through the fixing bracket 163. Through the detachable connection between the fixing bracket 163 and the unwinding frame 12, the operator can quickly complete the installation of the film pad 161, and can also conveniently remove it when necessary for replacement or maintenance, which greatly improves the use efficiency and flexibility of the equipment and reduces the time and labor costs caused by the difficulty of installation and disassembly.

[0060] Please refer to Figure 4 and Figure 5 In this embodiment, the electroplating device 2 includes a plating rack 21, a plating box 22, two plating rollers 23, a plurality of guide rollers 24 and a plurality of pressure rollers 25 arranged on the plating rack 21, and wire threading grooves 26 are arranged near the two ends of the plating roller 23 and near the two ends of the guide roller 24. The wire threading grooves 26 are arranged around the plating roller 23 or the guide roller 24. Specifically, the plating box 22 is arranged on the plating rack 21, and the plating box 22 contains the plating liquid; two plating rollers 23 are rotatably installed on the plating rack 21, arranged at intervals and located at the front end of the sheet conveying direction; multiple guide rollers 24 are rotatably installed on the plating rack 21, located at the rear end of the sheet conveying direction and arranged at intervals and staggered along the sheet conveying direction, and at least two guide rollers 24 are in contact with the plating liquid in the plating box 22; multiple pressure rollers 25 are movably installed on the plating rack 21, and can abut against the plating rollers 23 or the guide rollers 24 to press the sheet.

[0061] It should be noted that the plating roller 23 and the guide roller 24 are arranged in parallel and staggered manner along the conveying direction of the sheet, the plating roller 23 is located above the plating box 22, and the threading groove 26 is close to the two end edges of the plating roller 23 or the guide roller 24, that is, an annular groove structure is provided on the roller surface of the plating roller 23 or the guide roller 24 as the threading groove 26.

[0062] When the electroplating device 2 is performing the electroplating operation of the sheet, the upper surface and the lower surface of the sheet are passed through two electroplating rollers 23 in sequence, and under the guidance of multiple guide rollers 24, they enter the electroplating box 22 and contact the electroplating solution, thereby realizing double-sided electroplating of the sheet. Among them, the electroplating roller 23 and the guide roller 24 are both provided with threading grooves 26. When the sheet is first threaded through the film, threading wires can be pasted on both sides of the sheet. By passing the threading wires through the threading grooves 26 to drive the sheet through the electroplating roller 23 or the guide roller 24, the film threading operation of the sheet is greatly facilitated, and the accuracy and stability of the electroplating are improved. In addition, at least two guide rollers 24 are in contact with the electroplating solution, ensuring that the sheet can fully contact the electroplating solution during the transportation process, and achieving a uniform electroplating effect. Through the coordinated use of multiple guide rollers 24 and the clamping roller 25, the sheet can be effectively guided and clamped to prevent it from being offset or wrinkled during the electroplating process, thereby ensuring the quality of electroplating and ensuring the stability of sheet transportation.

[0063] Please refer to Figure 4 In this embodiment, the pressing roller 25 is movably connected to the electroplating rack 21 through a roller lifting mechanism 27. The roller lifting mechanism 27 is two groups arranged on the electroplating rack 21, and the two groups of roller lifting mechanisms 27 are respectively connected to the two ends of the pressing roller 25. The two groups of roller lifting mechanisms 27 are symmetrically arranged on the electroplating rack 21, and are respectively used to drive the two ends of the pressing roller 25, so that the movements of the two ends of the pressing roller 25 can be kept synchronous.

[0064] The setting of the roller lifting mechanism 27 enables the pressing roller 25 to be flexibly raised and lowered, which is convenient for the film-passing operation of the sheet and the adjustment of the electroplating process. When film-passing is required, the roller lifting mechanism 27 can lift the pressing roller 25 so that the sheet can easily pass between the electroplating roller 23 and the guide roller 24; and when the electroplating process is in progress, the roller lifting mechanism 27 can lower the pressing roller 25 so that it abuts against the electroplating roller 23 or the guide roller 24 to achieve the pressing of the sheet. This method is very flexible to operate, greatly improves work efficiency, and reduces the difficulty of operation.

[0065] Specifically, the roller lifting mechanism 27 includes a roller lifting cylinder 271 and a linkage 272. The roller lifting cylinder 271 is installed on the electroplating rack 21. The linkage 272 is rotatably installed on the electroplating rack 21. The two ends of the linkage 272 are rotatably connected to the output shaft of the roller lifting cylinder 271 and one end of the pressing roller 25. The linkage 272 includes a first connecting plate 2721, a transfer shaft 2722 and a second connecting plate 2723. The transfer shaft 2722 is rotatably installed on the electroplating rack 21, and its two ends are fixedly connected to one end of the first connecting plate 2721 and one end of the second connecting plate 2723 respectively. The other end of the first connecting plate 2721 is rotatably connected to the output shaft of the roller lifting cylinder 271, and the other end of the second connecting plate 2723 is connected to the end of the pressing roller 25.

[0066] The linkage part 272 of this embodiment adopts a split design, which makes the manufacture and assembly of each component more convenient. The setting of the adapter shaft 2722 is the main component. Its function is to install the first connecting plate 2721 and the second connecting plate 2723 on the inner and outer sides of the plating rack 21 respectively, so as to facilitate the connection between the clamping roller 25 and the roller lifting cylinder 271. That is, by installing the roller lifting cylinder 271 and the clamping roller 25 in different areas, the roller lifting cylinder 271 is avoided from interfering with the conveying of the sheet, and the installation space on the plating rack 21 is reasonably utilized, thereby improving the space utilization rate and facilitating the position layout of the roller lifting mechanism 27.

[0073] The two connecting seats 3241 are respectively connected to one end of multiple heating tubes 3242, which is convenient for the installation of the heating tubes 3242 and is conducive to maintaining the consistency of the horizontality of the heating tubes 3242. The heating mechanism 324 can also be suspended inside the box body 321 to avoid direct contact between the heating mechanism 324 and the upper box cover 322 or the lower box cover 323, thereby avoiding the heating mechanism 324 from affecting the upper box cover 322 or the lower box cover 323.

[0074] In addition, please refer to Figure 8, guide mechanisms 325 are provided at the material guide ports 3211 on both sides of the box body 321, and the length of the guide mechanisms 325 is slightly longer than the length of the material guide ports 3211, and the guide mechanisms 325 are used to guide the materials to be processed into the interior of the box body 321. Specifically, the guide mechanisms 325 include an upper guide piece 3251 and a lower guide piece 3252 that are arranged opposite to each other, and both the upper guide piece 3251 and the lower guide piece 3252 are "L"-shaped structures, and the upper guide piece 3251 and the lower guide piece 3252 are respectively located at the upper and lower sides of the material guide port 3211, and a gap is left between the upper guide piece 3251 and the lower guide piece 3252 for the materials to be processed to pass through, and both the upper guide piece 3251 and the lower guide piece 3252 extend along the length direction of the material guide port 3211.

[0076] Please refer to Figure 6 In this embodiment, the hot air mechanism 33 includes two hot air pipes 331 arranged opposite to each other, and a plurality of air holes 332 are arranged on opposite sides of the two hot air pipes 331; the cooling mechanism 34 includes a heat sink 341 and two groups of heat dissipation fans 342, and the two groups of heat dissipation fans 342 are arranged opposite to each other in the heat sink 341, and opposite sides of the heat sink 341 are provided with material passing ports, and the material passing ports are located between the two groups of heat dissipation fans 342. Among them, the two hot air pipes 331 and the heat sink 341 can be fixed on the drying rack 31 by a bracket. The two hot air pipes 331 and the two groups of heat dissipation fans 342 are arranged vertically at intervals, and the channel left between the two hot air pipes 331 and the channel for outflow between the two groups of heat dissipation fans 342 are opposite to the material guide port 3211.

[0077] Two opposing hot air pipes 331 can blow out hot air from a plurality of air holes 332 on opposing surfaces to form an air curtain, and the sheet passes through between the two hot air pipes 331 to complete the second drying, which is beneficial to reducing energy consumption and improving heat utilization rate; the cooling mechanism 34 has two groups of cooling fans 342 relatively arranged inside the heat dissipation box 341, which is beneficial to uniform cooling of the front and back sides of the sheet and improving the cooling efficiency. At the same time, a feeding port is provided to facilitate the positioning of the sheet.

[0078] It should be noted that the multiple air holes 332 on the two hot air pipes 331 can be staggered relative to each other, and the blowing angles between the air holes 332 on the two opposite hot air pipes 331 can be symmetrical, so that the wind forces on the front and back sides of the sheet can be similar or the same when passing between the hot air pipes 331, thereby reducing possible shaking of the sheet.

[0079] Please refer to Fig. 9 and Fig.10 In this embodiment, the winding frame 42 is provided with a winding shaft 421, a winding drive 422 for driving the winding shaft 421 to rotate, and a plurality of winding rollers arranged at intervals on the winding frame 42. The winding drive 422 is a motor, which can be fixed to the winding frame 42 through a support mechanism such as a bracket, and the output shaft of the motor can be fixedly connected to one end of the winding shaft 421 through a coupling. In addition, the plurality of winding rollers can be installed on the winding frame 42 in a certain arrangement according to actual needs, and their function is to tension the sheet and guide the sheet smoothly to the winding shaft, and the specific arrangement can be flexibly designed.

[0080] Please continue to refer to Fig. 9 In this embodiment, the film pressing assembly 43 includes a rotating rod 431, a connecting rod 432 and a pressure roller 433. The rotating rod 431 is rotatably mounted on the winding frame 42. The connecting rod 432 is fixedly connected to the rotating rod 431. The pressure roller 433 is rotatably connected to the connecting rod 432 and can abut against the winding shaft 421. Specifically, the winding frame 42 of this embodiment is a "U"-shaped structure as a whole, which can facilitate the installation of shaft parts. Shaft parts, such as the rotating rod 431 and the movable roller shaft, are all installed on the "U"-shaped structure.

[0081] The pressure roller 433 can swing relative to the rotating rod 431 through the connecting rod 432, that is, when the rotating rod 431 rotates, the pressure roller 433 can synchronously rotate with the rotating rod 431 as the rotation axis, and the pressure roller 433 can abut against the winding shaft 421. Therefore, when the winding shaft 421 is winding, the pressure roller 433 can always press against the winding shaft 421, that is, the material roll can be squeezed and exhausted, so that the sheet can be effectively flattened and compacted during the winding process, avoiding problems such as looseness and wrinkling of the sheet after winding, thereby improving the overall quality and aesthetics of the wound sheet.

[0082] In addition, the film pressing assembly 43 also includes a film pressing driving member 434, the output end of which is connected to the rotating rod 431 and is used to drive the rotation of the rotating rod 431. Specifically, the film pressing driving member 434 is installed on the outside of the winding frame 42, and one end of the rotating rod 431 extends out of the winding frame 42 and is connected to the output end of the film pressing driving member 434. The film pressing driving member 434 includes a film pressing cylinder 4341 and a crank 4342. The film pressing cylinder 4341 is arranged on the winding frame 42, and the output shaft of the film pressing cylinder 4341 is provided with a transfer block 4343, one end of the crank 4342 is rotatably connected to the transfer block 4343, and the other end is fixedly connected to the rotating rod 431. The design of the crank 4342 ingeniously converts the linear motion of the film pressing cylinder 4341 into the rotational motion of the rotating rod 431, so that the rotation of the pressing roller 433 is more stable and uniform, avoiding the problem of sheet damage or uneven compaction caused by uneven force.

[0083] Please refer to Fig.10In this embodiment, a film cutting assembly 44 and a waste recovery assembly 45 are also provided on the winding frame 42. The film cutting assembly 44 is divided into two groups that are spaced apart and arranged opposite to each other. The two groups of film cutting assemblies 44 are respectively used to cut the opposite side edges of the sheet material; the waste recovery assembly 45 is two groups that match the film cutting assembly 44 and are used to recover the waste of the sheet material after cutting.

[0084] The film cutting component 44 of this embodiment can accurately cut the opposite side edges of the slice material, ensure the neatness and consistency of the sheet material, improve the qualified rate of the product, and cooperate with the waste recovery component 45 to recover the cut sheet waste in real time, avoiding the scattering and accumulation of waste material and keeping the production environment clean and hygienic.

[0085] In this embodiment, the film cutting assembly 44 includes a support seat 441 disposed on the winding frame 42, a mounting frame 442 disposed on the support seat 441, a film cutting motor 443 disposed on the mounting frame 442, and a cutter 444 disposed on the output shaft of the film cutting motor 443, and the cutter 444 is close to one of the winding roller shafts. The support seat 441 can slide relative to the winding frame 42, so that the position of the cutter 444 can be adjusted to meet different product requirements.

[0086] Through the coordinated use of the support seat 441 and the mounting frame 442, the film cutting motor 443 and the cutter 444 are firmly mounted on the winding frame 42, ensuring stability and accuracy during the film cutting process. In addition, the cutter 444 is close to one of the guide rollers, and the guide roller is used as a support, so that the sheet can be quickly cut by the cutter 444 after passing through the guide roller 23, reducing the deviation and deformation of the sheet during the transmission process.

[0087] Please continue to refer to Fig.10 In this embodiment, the waste recovery assembly 45 includes a mounting plate 451 disposed on the winding frame 42, a recovery motor 452 disposed on the mounting plate 451, and a waste shaft 453 connected to the output end of the recovery motor 452, and stop blocks 454 are disposed at both ends of the waste shaft 453. By winding the waste on the waste shaft 453, the waste shaft 453 is driven to rotate by the recovery motor 452 to achieve waste recovery. In addition, stop blocks 454 are disposed at both ends of the waste shaft 453, which can not only prevent the waste from slipping or scattering during the recovery process, ensure the smooth recovery of the waste, but also protect the waste shaft 453 from being damaged during the rotation process.

[0088] Please refer to Figure 2 and Fig. 9In this embodiment, both the unwinding seat 11 and the winding seat 41 are provided with an adjustment component 17, and the adjustment component 17 includes an adjustment block 171, an adjustment rod 172 and a handle 173. The adjustment block 171 is fixed to the unwinding seat 11 or the winding seat 41, and the adjustment rod 172 is threadedly connected to the adjustment block 171. One end of the adjustment rod 172 is connected to the handle 173, and the other end is connected to the unwinding frame 12 or the winding frame 42 through an extension plate.

[0089] The adjustment component 17 plays a locking and adjusting role. By rotating the handle 173, the adjustment rod 172 is rotated. Since the adjustment rod 172 is threadedly connected to the mounting block and is connected to the unwinding frame 12 or the winding frame 42 through an extension plate, the adjustment rod 172 will synchronously drive the unwinding frame 12 or the winding frame 42 to move when rotating, thereby realizing the position adjustment of the unwinding frame 12 or the winding frame 42. The structure is simple and easy to use.

[0090] Please refer to Fig.11 and Fig.12 It should be noted that the feed roller 15 and the take-up roller of this embodiment are both mounted on the unwinding frame 12 or the take-up frame 42 through a fixing assembly 5. Taking the unwinding frame 12 as an example, the two ends of the feed roller 15 are respectively mounted through a fixing assembly 5. The fixing assembly 5 includes a fixing seat 51, a clamping member 52 and an adjusting member 53. The fixing seat 51 is mounted on the unwinding frame 12, the clamping member 52 is movably mounted on the fixing seat 51, and the adjusting member 53 is disposed on the fixing seat 51 and is used to adjust the position of the clamping member 52 on the fixing seat 51. Among them, the two ends of the feed roller 15 are respectively mounted on two clamping members 52, one of the adjusting members 53 is used to adjust the horizontal position of one end of the feed roller 15, and the other adjusting member 53 is used to adjust the vertical position of the other end of the feed roller 15.

[0091] The movable clamping member 52 arranged on the fixed seat 51 can clamp one end of the roller shaft, and the position of one end of the roller shaft is changed by adjusting the adjusting member 53, so as to achieve the position adjustment of one end of the roller shaft. Among them, the installation directions of the two relatively arranged fixing components 5 are different, so that the horizontal or vertical positions of the two ends of the roller shaft can be adjusted. For example, one of the fixing components 5 adjusts the horizontal position of one end of the roller shaft, and the other fixing component 5 adjusts the vertical position of the other end of the roller shaft. Through the two-way adjustment, the position and angle of the roller shaft can still be adjusted after installation, ensuring that the horizontality and verticality of the roller shaft can meet the use requirements, reducing the vibration and wear of the roller shaft, and improving the stability and durability of the roller shaft, thereby improving the stability and accuracy of the equipment operation.

[0092] The clamping member 52 includes a first clamping block 521 and a second clamping block 522. The second clamping block 522 is in an "L"-shaped structure. The first clamping block 521 and the second clamping block 522 are detachably connected. A slot for placing the bearing of the feed roller shaft 15 is formed between the first clamping block 521 and the second clamping block 522. In addition, a slide slot is provided on the fixed seat 51, and the second clamping block 522 is slidably installed in the slide slot. The adjusting member 53 is a screw rod, which is passed through the fixed seat 51 and is threadedly connected to the second clamping block 522. When the screw rod rotates, it can drive the second clamping block 522 and synchronously drive the clamping member 52 to move, thereby achieving the purpose of adjusting the end position of the feed roller shaft 15.
