[0024] The inner rotating disc rotating drive mechanism is relatively common, such as disclosed in the patent document CN221758877U double-station collecting device, which will not be repeated here.

[0025] The base 1 is provided with a collecting station, a discharging station and an intermediate station, the collecting station is connected with a punch, the discharging mechanism 6 is arranged at the discharging station, and the intermediate station can be used for threading copper pipes and positioning needles for the fin stack, so that the space is large and manual operation is convenient, each station is provided with a set of fin collector assembly, each set of fin collector assembly is connected with the fin collector moving mechanism, and the fin collector assembly is converted in position between the base 1 and the inner rotating disc 2 through the fin collector moving mechanism.

[0026] The discharging mechanism 6 is the same as or similar to the discharging mechanism in the patent document CN221758877U fin storage and retrieval machine, which will not be repeated here.

[0027] The fin collector assembly includes a fin collector (collecting rack) 4 and a fin collector lifting mechanism 5.

[0028] The fin collector (collecting rack) 4 can adopt the fin collector in the patent document CN221758877U fin storage and retrieval machine, and the fin collector (collecting rack) 4 adopted in the embodiment includes a bottom plate 401, a collecting needle mounting plate 402, a lifting plate (lower supporting plate) 403, a turnover frame (upper supporting plate) 404, a guide rod 405, a righting plate 406, a lifting plate guide mechanism and a collecting needle 30.

[0029] A plurality of collecting needles 30 are vertically and spacedly mounted on the collecting needle mounting plate 402, and such a collecting needle mounting structure is relatively common in existing collecting racks, which will not be described in detail.

[0030] A plurality of equal-height limiting blocks 4011 are arranged on the bottom plate 401 to limit the lowest position of the lifting plate 403, and a hole 4012 for limiting the fin collector 4 is also arranged, and the position of the hole 4012 should correspond to the rotating shaft 705.

[0031] The aggregate needle mounting plate 402 is at least two or more in number, and is selected according to the length of the fin. In this embodiment, two aggregate needle mounting plates are parallelly mounted on the base plate 401 through respective adjusting plates 4021. A plurality of positioning holes 4022 are provided on the adjusting plate 4021, and the two ends of the aggregate needle mounting plate 402 are fixed on the positioning holes 4022 through screws 4023. Thus, the relative position between the two aggregate needle mounting plates 402 can be changed by mounting the aggregate needle mounting plate 402 at different positioning holes 4022, so as to change the distance between the aggregate needles 30 mounted on the aggregate needle mounting plate 402, to adapt to different lengths of the fin.

[0032] In order to conveniently adjust the position of the aggregate needle mounting plate 402, a sliding block sliding rail guide mechanism is further mounted between the aggregate needle mounting plate 402 and the adjusting plate 4021. The sliding block 4024 is mounted on the aggregate needle mounting plate 402, and the sliding rail 4025 is mounted on the adjusting plate 4021.

[0033] The lifting plate 403 is movably placed above the base plate 401.

[0034] The two ends of the righting plate 406 are placed on the lifting plate 403, and the righting plate 406 is provided with through holes 4061 through which the aggregate needles 30 pass. The diameter of the through holes 4061 is slightly larger than the diameter of the aggregate needles 30.

[0035] In order to better right the aggregate needles 30, especially when the aggregate needles are relatively long, an upper righting plate 4062 is further provided. The upper righting plate 4062 is parallelly arranged above the righting plate 406, and is also provided with through holes 4061 through which the aggregate needles 30 pass. The upper righting plate 4062 and the righting plate 406 are kept at a certain distance by a plurality of equal-height columns 4063 arranged between the upper righting plate 4062 and the righting plate 406, with the upper ends of the equal-height columns 4063 connected to the upper righting plate 4062 and the lower ends connected to the righting plate 406.

[0036] A lower righting plate 4064 can also be provided. The lower righting plate 4064 is parallelly arranged above the aggregate needle mounting plate 402, and is also provided with through holes 4061 through which the aggregate needles 30 pass. The lower righting plate 4064 and the aggregate needle mounting plate 402 are kept at a certain distance by a plurality of equal-height columns 4065 arranged between the lower righting plate 4064 and the aggregate needle mounting plate 402, with the upper ends of the equal-height columns 4065 connected to the lower righting plate 4064 and the lower ends connected to the aggregate needle mounting plate 402.

[0037] The lower end of the aggregate needle 30 is mounted on the aggregate needle mounting plate 402, and sequentially passes through the through holes 4061 of the lower righting plate 4064, the through holes 4061 of the righting plate 406, the through holes 4061 of the upper righting plate 4062, and passes through the lifting plate 403 and the turnover frame 404.

[0038] In order to move the lifting plate 403 smoothly, a lifting plate guiding mechanism is also provided, which includes a guide rod 405, the lower end of which is installed on the aggregate needle mounting plate 402, and the upper end of which passes through the lifting plate 403, the righting plate 406 and the turnover frame 404 in turn, so that when the lifting plate 403 moves up and down, it can be guided by the guide rod 405.

[0039] In this way, the lifting plate 403 can move up and down smoothly through the guide of the guide rod 405 and the sliding block 505 and the sliding rail 504 of the guiding mechanism of the above-mentioned sheet lifting mechanism 5.

[0040] The turnover frame 404 is placed on the lifting plate 403, and both sides thereof are provided with plug-in holes 4041 which can be movably connected by being inserted by the turnover plug-in rod of the turnover mechanism 6. The turnover frame 404 is also provided with a plurality of reinforcing rib plates 4042, the installation positions of which are determined according to the principle of not interfering with the aggregate needle 30 and the guide rod 405, so as to increase the strength of the turnover frame 404 and ensure the smooth lifting and turnover of the finned sheet pile.

[0041] In order to facilitate the unloading of the finned sheet pile, several positioning steel needles (not shown in the figure) are generally inserted into each column of fins after the collection of the aggregate, so several installation positions of the plurality of reinforcing rib plates 4042 are consistent with the positions of the inserted positioning steel needles, and the upper parts of these reinforcing rib plates 4042 are provided with non-through grooves 40421, so that the steel needles pass through the upper part of the finned sheet pile and are located in the grooves 40421 at the lower part, and are dragged by the bottom surface of the reinforcing rib 4042, so as not to fall to the bottom plate 401.

[0042] The turnover frame 404 and the lifting plate 403 are combined into one through a positioning mechanism, the specific structure of which in this embodiment is that positioning pins 409 are arranged on both sides of the lifting plate 403, and corresponding positioning pin holes (not shown in the figure) are arranged on the corresponding positions of the turnover frame 404, so that when the turnover frame 404 is lowered onto the lifting plate 403, the positioning pins 409 on the lifting plate 403 are inserted into the positioning pin holes of the turnover frame 404, thereby ensuring the combination accuracy of the two.

[0043] In order to prevent the upper part of the higher finned sheet pile from tilting, a baffle plate 410 is also provided, which is installed on the adjusting plate 4021 through a supporting guide rod 4101 and a supporting plate 4102, both ends of the supporting plate 4102 are also installed on the adjusting plate 4021, so as to facilitate the adjustment of the position of the baffle plate 410 in the horizontal direction, the lower end of the supporting guide rod 4101 is installed on the supporting plate 4102, and the upper part passes through the lifting plate 403 and the turnover frame 404 in turn, both ends of the baffle plate 410 are supported by the supporting guide rod 4101 and are movably connected with the supporting guide rod 4101, so as to facilitate the adjustment of the height of the baffle plate 410.

[0044] The bottom surface of the bottom plate 401 is also provided with a guide shaft 4014, which cooperates with the steering groove 102 on the base and the turntable guide groove 202 on the turntable, cooperates with the guide groove 103 on the base and the turntable guide groove 202 on the turntable, and is always located in the groove communicated with the steering groove 102 and the turntable guide groove 202, and the groove communicated with the guide groove 103 and the turntable guide groove 202. In this embodiment, the steering groove 102 is arranged at the unloading station, the guide groove 103 is arranged at the collecting station and the intermediate station, and during the movement of the collector 4 from the base 1 to the inner turntable 2 by the collector moving mechanism 7 of the collecting station, the collector 4 rotates around the rotating shaft 705, the guide shaft 4014 moves along the steering groove 102 to the turntable guide groove 202, and when the collector moving mechanism 7 stops moving the collector 4, the collector 4 is moved from the base to the inner turntable, and at the same time, rotates 90 degrees clockwise around the rotating shaft 705, and the guide groove 103 of the unloading station only plays a role in smoothly moving the collector 4 from the inner turntable 2 to the base 1.

[0045] In order to ensure that the collector 4 successfully collects materials at the collecting station, two positioning holes 4013 are arranged on the bottom plate 401, and a positioning mechanism is used for positioning, which includes a gas cylinder 801 and a positioning column 802. The gas cylinder 801 is installed on the base 1 and connected with the positioning column 802. Each positioning hole 4013 corresponds to a positioning mechanism, and the positioning column 802 can be inserted into or withdrawn from the positioning hole 4013 by the extension and retraction of the piston rod of the gas cylinder 801. During the collecting process, the positioning column 802 is inserted into the positioning hole 4013, and after the collection is completed, the positioning column 802 is withdrawn from the positioning hole 4013.

[0046] The collector lifting mechanism 5 includes a motor 501, a lead screw 502, and a lead screw nut 503. The motor 501 is installed on a lifting frame 5011, and the output shaft is connected with the lead screw 502. The lifting frame 5011 is installed on the bottom plate 401 of the collector 4. The upper and lower ends of the lead screw 502 are rotatably supported by the lifting frame 5011. The lead screw nut 503 is sleeved on the lead screw 502 and is fixedly connected with the lifting plate 403 of the collector 4. In this way, the rotation of the lead screw 502 driven by the motor 501 causes the lifting plate 403 to move up and down.

[0047] In order to move the lifting plate 403 up and down smoothly and increase the strength of the lifting plate 403, a lifting plate guide mechanism is also provided, which includes a sliding rail 504 and a sliding block 505. The sliding rail 504 is installed on the lifting frame 5011, and the sliding block is installed on the lifting plate 403. In this way, the lifting plate 403 can move smoothly relative to the lifting frame 5011 through the sliding block 505 and the sliding rail 504.

[0048] The base 1 is provided with a sliding groove 101, and the inner rotating disc 2 is provided with a rotating disc sliding groove 201 communicating with the sliding groove 101.

[0049] The sheet collector moving mechanism comprises a cylinder 701, a push rod 702 and a rotating shaft 705. The cylinder 701 is installed on the inner rotating disc 2, and the piston rod thereof is connected with the push plate 702. The rotating shaft 705 is installed on the push rod 702 and is always located in the hole on the bottom plate 401 of the sheet collector 4. Thus, when the piston rod of the cylinder 701 is extended or retracted, the push plate 702 is moved along the rotating disc sliding groove 201 and the sliding groove 101, and the rotating shaft 705 drives the sheet collector 4 to move to the base 1 or the inner rotating disc 2.

[0050] In order to make the sheet collector 4 move stably when changing the position between the inner rotating disc 2 and the base 1, and to make the sheet collector 4 rotate at a set angle during the changing process, the base 1 is further provided with a turning groove 102 and a guide groove 103. The turning groove 102 is provided at the unloading station and is designed as a curve to ensure the sheet collector 4 to rotate at a required angle around the rotating shaft 705. The guide groove 103 is provided at the material collecting station and the intermediate station and is a straight groove. If the sheet collector at the unloading station does not need to rotate at a certain angle, the turning groove 102 can also be designed as a straight groove like the guide groove 103. The inner rotating disc 2 is provided with a rotating disc guide groove 202 connected with the turning groove 102 and the guide groove 103 respectively.

[0051] The sheet collector moving mechanism moves the sheet collector 4 full of fins from the material collecting station to the inner rotating disc 2. The inner rotating disc 2 rotates at a set angle through the inner rotating disc rotating driving mechanism, and then the sheet collector moving mechanism moves the sheet collector 4 to the intermediate station. After the related operation is completed at the intermediate station, the sheet collector moving mechanism moves the sheet collector 4 to the inner rotating disc 2 again. The inner rotating disc 2 rotates at a set angle through the inner rotating disc rotating driving mechanism, and then the sheet collector moving mechanism moves the sheet collector 4 to the unloading station. Then the fins on the sheet collector 4 are unloaded through the unloading mechanism 6.

[0052] The inner rotating disc 2 drives the sheet collector 4 to rotate during the rotating process, and also drives the sheet collector lifting mechanism 5 to rotate. Thus, during the process of pushing the sheet collector 4 back to the material collecting station after the unloading is completed, the lifting mechanism 5 can start to work to lift the lifting plate 403 and the turnover frame 404 to a set height. After the sheet collector 4 is pushed to the position, the material collecting can be directly started. Thus, the pushing stroke does not need to be set very long, and waiting is not needed, so a lot of time is saved.

[0053] The left and right uprights 6011 and 6012 of the above-mentioned unloading mechanism 6 are movable relative to the base 1, thus preventing collision with the rotating gatherer 4. When the gatherer 4 is to be brought to the unloading station or to be removed from the unloading station, the left and right uprights 6011 and 6012 are both moved away, away from the gatherer.

[0054] The present access machine further comprises a partition 9, which separates the three stations, thus ensuring the safety of the operator when working at the intermediate station and the unloading station.
