[0031] A lower track 203 intersecting the upper track 202 is provided inside the upper fixed seat 201 below the upper track 202. The lower track 203 is in a "W"-shaped structure, and two downward arc-shaped areas of the lower track 203 match the sizes of the pickling tank 102 and the water washing tank 103 respectively.

[0032] A second slide groove 2013 is provided inside the upper fixing seat 201 at the bottom of the upper track 202 and penetrates to the bottom of the upper fixing seat 201. The T-shaped slide bar 204 penetrates to the bottom of 201 through the second slide groove 2013 and is connected to the storage assembly 3;

[0033] The bottom wall of the upper fixing seat 201 is located above the conveyor belt 104 and is fixedly connected with a drying device 2010 for drying the galvanized workpieces;

[0034] The storage component 3 includes:

[0035] A storage box 301 is fixedly connected to the bottom wall of the T-shaped slide bar 204, and a storage slot 302 is provided inside the storage box 301. A spring 303 is fixedly connected to the upper wall of the storage slot 302, and a third baffle 304 is fixedly connected to the bottom end of the spring 303. Solid blocks 305 are fixedly connected to the outer walls of both sides of the third baffle 304;

[0036] A limiting groove 308 is provided at the bottom of the storage groove 302 inside the storage box 301, and the length and width of the limiting groove 308 match the length and width of the third baffle 304 respectively;

[0037] A third sliding groove 306 is provided on the outer wall of the storage box 301 at the solid block 305 , and the height of the third sliding groove 306 matches the sliding track of the solid block 305 .

[0038] In this embodiment: when the hot-dip galvanizing pretreatment device is actually used, first open the door panel of the outer wall of the storage box 301 to put the galvanized workpiece to be processed into the storage box 301, and then close the door panel, then start the electric push rod 208, the electric push rod 208 drives the slider 207 to move along one side of the column block 209, the slider 207 drives the fixed rod 205, the T-shaped slide bar 204, and the storage box 301 to slide synchronously along the inside of the upper track 202 until the T-shaped slide bar 204 moves to the intersection of the upper track 202 and the lower track 203. At this time, under the action of gravity, the fixed rod 205, the T-shaped slide bar 204, and the storage box 301 move downward synchronously and start to move along the lower track 203 toward the side of the column block 209. In this process, the storage box 301 passes through the upper track 202 in sequence. The galvanized workpieces are pickled and washed by acid pickling tank 102 and water washing tank 103 until the solid block 305 contacts the extrusion block 106. At this time, as the storage box 301 moves, the extrusion block 106 starts to squeeze the solid block 305, so that the solid block 305 drives the third baffle 304 to move and shrink along the inside of the storage tank 302 until the third baffle 304 is completely retracted to the inside of the storage tank 302. At this time, the outer wall of the storage box 301 is not blocked. At this time, the galvanized workpieces in the storage box 301 begin to transfer along the discharge hole 307 to the upper end of the conveyor belt 104. At this time, the drying equipment 2010 dries the galvanized workpieces at the upper end of the conveyor belt 104, and the dried galvanized workpieces are conveyed to the upper end of the storage table 105 through the conveyor belt 104;

[0039] After the unloading is completed, the electric push rod 208 is started again, and the electric push rod 208 starts to drive the T-shaped slide bar 204 to move along the lower track 203 to the inside of the upper track 202 and along the side away from the column block 209. The slider 207 drives the fixed rod 205, the T-shaped slide bar 204, and the storage box 301 to slide synchronously along the inside of the upper track 202 until the T-shaped slide bar 204 moves to the second intersection of the upper track 202 and the lower track 203. The reset second baffle 2012 blocks the groove at the intersection of the upper track 202 and the lower track 203 The plug makes it easy for the T-shaped slide bar 204 to slide smoothly inside the upper track 202. When the T-shaped slide bar 204 contacts the first baffle 2011, the T-shaped slide bar 204 pushes the first baffle 2011 to block the groove at the intersection of the upper track 202 and the lower track 203. Therefore, the slider 207 drives the fixed rod 205, the T-shaped slide bar 204, and the storage box 301 to slide synchronously along the upper wall of the first baffle 2011 and reset to the initial end of the upper track 202. Through the cooperation of the above parts, the pickling, washing and drying operations of the galvanized workpiece are completed quickly and conveniently.

[0040] Please refer to Figure 6 An outer wall of the storage box 301 is provided with a discharge hole 307 at the third baffle 304 , and the size of the discharge hole 307 is larger than the size of the workpiece placed inside the storage box 301 .

[0041] In this embodiment: this structure can facilitate the complete discharge operation of the workpiece, avoiding the situation where the workpiece remains inside the storage box 301.

[0042] Please refer to Figures 1-2 The inner wall of the upper fixed seat 201 is located at the intersection of the upper track 202 and the lower track 203, and is rotatably connected with the first baffle 2011 and the second baffle 2012 in sequence. The length of the first baffle 2011 and the second baffle 2012 is greater than the length of the groove at the intersection of the upper track 202 and the lower track 203, and the width of the first baffle 2011 and the second baffle 2012 are both smaller than the distance from the inner wall of the upper fixed seat 201 to the outer wall of the T-shaped sliding bar 204 away from the fixed rod 205.

[0043] In this embodiment: it is necessary to supplementally explain that: the bottom end of the inner wall of the upper track 202 is formed with a storage rotating groove for accommodating the first baffle 2011 and the second baffle 2012. When the first baffle 2011 and the second baffle 2012 are horizontal, the surfaces of the first baffle 2011 and the second baffle 2012 are flush with the bottom of the inner wall of the upper track 202. The first baffle 2011 and the second baffle 2012 are formed with a rotating shaft rotatably connected to the inner wall of the upper fixed seat 201 on both sides, and a torsion spring is sleeved on the outer side of the rotating shaft. The two ends of the torsion spring are respectively engaged with the surfaces of the first baffle 2011 and the second baffle 2012 and the inner wall of the upper fixed seat 201. The first baffle 2011 is initially in an upward tilted state, and it does not block the port of the lower track 203. The second baffle 2012 is initially in a horizontal state, and the other port of the lower track 203 is blocked.

[0044] In order to enable the fixed rod 205, the T-shaped slide bar 204, and the storage box 301 to synchronously slide along the inside of the upper rail 202 and reset to the initial end of the upper rail 202, a first baffle 2011 and a second baffle 2012 that are larger than the length of the groove at the intersection of the upper rail 202 and the lower rail 203 are set, so that the T-shaped slide bar 204 can push the first baffle 2011 and the second baffle 2012 to block the groove during the sliding process, thereby facilitating the smooth sliding of the T-shaped slide bar 204.

[0045] Please refer to Figures 4 to 6 The upper wall of the base 101 is located at the front end of the conveyor belt 104 and is fixedly connected with an extrusion block 106 . The height of the extrusion block 106 is greater than the height from the upper wall of the base 101 to the solid block 305 .

[0046] In this embodiment: In order to achieve the purpose of automatic unloading of the galvanized workpieces inside the storage box 301, an extrusion block 106 is set at the upper end of the base 101, so that when the solid block 305 contacts the extrusion block 106, the extrusion block 106 squeezes the solid block 305 so that the solid block 305 drives the third baffle 304 to move and shrink along the inside of the storage groove 302, and the third baffle 304 shrinks and moves upward so that the galvanized workpiece can be discharged from the discharge hole 307, thereby achieving the purpose of automatic unloading.
