In use, the steel belt is first released by the material releasing machine, then leveled by the leveling machine, and then conveyed by the feeding machine. The steel belt is then stamped and formed into a workpiece by the stamping device, and then the workpiece is conveyed out by the feeding device. However, after the workpiece is conveyed out by the feeding device, the workpiece conveyed out by the feeding device needs to be manually stacked together by the operator in a top-to-top manner to form a stacking unit, and then the stacking unit is sent into and stacked in a material loading box to save the space for storing the workpiece. However, when mass production is carried out, the manual stacking of the workpiece by the operator and the sending and stacking of the stacking unit into the material loading box often cause a large workload for the operator, which cannot meet the industry demand.

[0026] In the following, the application will be further described in conjunction with the drawings and the specific embodiments. It should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments without conflict.

[0027] As Figures 1-8As shown, a cooling tower structural member production line comprises a feeding machine 101, a leveling machine 102, a feeding machine 103, a punching device 110, and a feeding device 104 arranged in sequence; the cooling tower structural member production line further comprises a carrying box 120, a downward driving device 130 for driving the carrying box 120 to descend, a carrying table 140 for carrying workpieces 310, a pushing rod mechanism 150 for pushing the workpieces 310 along the length direction of the carrying table 140 from the carrying table 140 to the carrying box 120, a pushing moving device 160 for driving the pushing rod mechanism 150 to move along the width direction of the carrying table 140, and a stacking device 200; the stacking device 200 is used for overturning one of the two adjacent workpieces 310 on the carrying table 140 and stacking it on the other workpiece 310 of the two adjacent workpieces 310; and the feeding device 104 is used for transferring the workpieces 310 punched and formed by the punching device 110 to the end of the carrying table 140 away from the carrying box 120 one by one.

[0028] In work, the steel strip coil is wound on the feeding machine 101, and the steel strip is released from the feeding machine 101, then leveled by the leveling machine 102, conveyed by the feeding machine 103, punched and formed into the workpieces 310 by the punching device 110, and transferred to the carrying table 140 one by one by the feeding device 104, and then pushed from the carrying table 140 to the carrying box 120 along the length direction of the carrying table 140 by the pushing rod mechanism 150; in the process, the two adjacent workpieces 310 on the carrying table 140 can be stacked together and formed into a stacking unit by the stacking device 200, and after the two workpieces 310 to be stacked together and formed into a stacking unit are sent into the carrying box 120, the carrying box 120 is driven to descend by the downward driving device 130 for the height of a group of stacking units, so that the next group of stacking units can be stacked on the previous group of stacking units when they are sent into the carrying box 120, so that the stacking units in the carrying box 120 are placed in a stacked manner, which can save space, and then the work continues in the above-mentioned manner, so that the cooling tower structural member production line provided by the application can stack the two adjacent workpieces 310 together, send the stacking units into and stack them in the carrying box 120, so that the workpieces 310 do not need to be manually stacked by the operator, and the stacking units do not need to be manually sent into and stacked in the carrying box 120 by the operator, which can reduce the participation of the operator and reduce the workload of the operator.

[0029] The pushing rod mechanism 150 comprises a linkage seat 151 extending along the length direction of the bearing table 140, a plurality of pushing rods 152 arranged in sequence on the linkage seat 151 along the length direction of the bearing table 140 and used for pushing the workpieces 310, and a translation driving part 153 used for driving the linkage seat 151 to move along the length direction of the bearing table 140. When the translation driving part 153 drives the linkage seat 151 to move along the length direction of the bearing table 140 towards the loading box 120, the workpieces 310 on the bearing table 140 can be pushed forward by the plurality of pushing rods 152 on the linkage seat 151.

[0030] The translation driving part 153 is a first driving cylinder, and the linkage seat 151 is connected with the piston rod of the first driving cylinder. By using the first driving cylinder as the translation driving part 153, the installation can be facilitated.

[0031] The cooling tower structural member production line further comprises a machine shell 161, the pushing device 160 comprises a moving seat 162 movably mounted on the machine shell 161, and a longitudinal driving component 163 for driving the moving seat 162 to move along the width direction of the bearing table 140; the linkage seat 151 is movably mounted on the moving seat 162, and the cylinder body of the first driving cylinder is fixed on the moving seat 162. In the embodiment, the table top of the bearing table 140 can be defined as a plurality of feeding areas arranged in sequence along the length direction of the bearing table 140, the number of the feeding areas corresponds to the number of the poking rods 152, the feeding area closest to the material loading box 120 is formed as a last first feeding area, and the feeding area adjacent to the last first feeding area is formed as a last second feeding area. When the translational driving component 153 drives the linkage seat 151 to move along the length direction of the bearing table 140 towards the material loading box 120, each poking rod 152 can be driven to move from above the current feeding area to above the next feeding area, so as to push the workpieces 310 in the current feeding area to the next feeding area through the poking rod 152. Then, the longitudinal driving component 163 drives the moving seat 162 to move leftwards along the width direction of the bearing table 140, so that the linkage seat 151 and the poking rods 152 move away from the bearing table 140 together with the moving seat 162. Then, the translational driving component 153 drives the linkage seat 151 to move along the length direction of the bearing table 140 away from the material loading box 120, so that each poking rod 152 moves back to the position of the previous feeding area. Then, the longitudinal driving component 163 drives the moving seat 162 to move rightwards along the width direction of the bearing table 140, so that the poking rods 152 move rightwards to above the bearing table 140. Then, the translational driving component 153 drives the linkage seat 151 to move along the length direction of the bearing table 140 towards the material loading box 120, so as to drive each poking rod 152 to move from above the current feeding area to above the next feeding area, so as to push the workpieces 310 in the current feeding area to the next feeding area through the poking rod 152. In this way, the workpieces 310 on the bearing table 140 are gradually pushed towards the material loading box 120 along the length direction of the bearing table 140 through the feeding device 104. By adopting the above structure of the poking rod mechanism 150 and the pushing device 160, the workpieces 310 can be gradually pushed forward, the stability of the stacking unit can be improved, and the stacking device 200 can be conveniently matched with the stacking unit.

[0032] The longitudinal driving component 163 is a second driving cylinder, and the moving seat 162 is connected with the piston rod of the second driving cylinder. By adopting the second driving cylinder as the longitudinal driving component 163, the installation can be facilitated.

The stacking device 200 further comprises a lifting driving device 240 for driving the fixing device 210 to lift. When the linkage seat 151 and the pushing rod 152 move away from the bearing table 140 together with the moving seat 162, the fixing device 210 is driven to descend by the lifting driving device 240, and is driven to move towards the workpiece 310 in the second feeding area by the in-out device 220, so as to make the fixing device 210 enter the inner cavity 311 of the workpiece 310. When the fixing device 210 is fixed in the inner cavity 311 of the workpiece 310, the fixing device 210 is rotated by 180° by the rotating device 230, so that the workpiece 310 is rotated to have a top end downwardly, and then the workpiece 310 with the top end downwardly is stacked on the top end of the workpiece 310 in the first feeding area. Thus, the stacking of the two workpieces 310 adjacent to each other and closest to the loading box 120 on the bearing table 140 can be completed. Of course, in addition thereto, in the actual working process, the stacking device 200 can also be used to stack the two workpieces 310 adjacent to each other at other positions on the bearing table 140, but the stacking of the two workpieces 310 adjacent to each other and closest to the loading box 120 on the bearing table 140 by the stacking device 200 is the preferred embodiment of the present application, which can facilitate the subsequent stacking unit to be moved into the loading box 120.

[0046] Of course, in addition to this, the punching device 110 can also use any existing punching device on the market, as long as it can be punched and formed into a workpiece 310 according to the processing requirements.

[0047] Among them, the feeding device 104 can use any existing feeding device on the market, as long as it can be used to transfer the workpiece 310 punched and formed by the punching device 110 to the bearing table 140, for example, a push plate and a push cylinder that drives the push plate to move.

[0048] The end of the loading box 120 facing the loading platform 140 is provided with an inlet extending along the height direction of the loading box 120, and the top end of the loading box 120 is provided with a top opening. The downward driving device 130 comprises a side seat 131, a second screw rod 132 rotatably installed on the side seat 131 and vertically arranged, a fourth driving motor 133 for driving the second screw rod 132 to rotate, a second screw rod nut 132 matchedly sleeved on the second screw rod 132, and a supporting frame 134 liftably installed on the side seat 131 and used for supporting the loading box 120. The second screw rod nut is fixed on the supporting frame 134, and the side of the loading platform 140 facing the inlet of the loading box 120 is formed into a limiting surface. The workpiece 310 in the loading box 120 lowered below the surface of the loading platform 140 can be limited by the limiting surface. In use, after a group of stacked units are moved into the loading box 120, the fourth driving motor 133 drives the second screw rod 132 to rotate forward, so as to drive the second screw rod nut to lower the supporting frame 134 and the loading box 120 by a height distance of a group of stacked units, so that the next group of stacked units can be pushed and stacked on the previous group of stacked units in the loading box 120. By using the above structure of the downward driving device 130, the supporting frame 134 and the loading box 120 can be lowered step by step, so that the groups of stacked units can be sequentially stacked in the loading box 120 along the height direction of the loading box 120. After the loading box 120 is filled with workpieces 310, the movable side plate of the loading box 120 can be inserted into the loading box 120 to close the inlet, and the top cover is installed. At this time, the loading box 120 can be removed from the supporting frame 134. After the supporting frame 134 is raised to the top, another loading box 120 can be placed on the supporting frame 134 to load workpieces 310.

[0049] In the actual working process of the cooling tower structural member production line, after the pushing rod mechanism 150 pushes a plurality of workpieces 310 into the plurality of feeding areas respectively, one of the stacking devices 200 can be moved to the position corresponding to the last second feeding area by the moving device 170. The stacking device 200 turns over the workpieces 310 in the last second feeding area by 180° and stacks them on the workpieces 310 in the last first feeding area to form a stacking unit. Through the pushing of the pushing rod mechanism 150 and the moving of the moving device 170, the stacking unit enters the loading box 120. Then the loading box 120 is lowered by the lowering driving device 130 by a height of one stacking unit. Through the continuous working of the pushing rod mechanism 150 and the moving device 160, the subsequent plurality of workpieces 310 are pushed into the plurality of feeding areas by the pushing rod mechanism 150, and at the same time, the next stacking device 200 is moved to the position corresponding to the last second feeding area by the moving device 170. The next stacking device 200 turns over the workpieces 310 in the last second feeding area by 180° and stacks them on the workpieces 310 in the last first feeding area to form the next stacking unit. Through the pushing of the pushing rod mechanism 150 and the moving of the moving device 170, the next stacking unit enters the loading box 120 and is stacked on the previous stacking unit. Then the above-mentioned mode is continuously worked to complete the stacking of the workpieces 310.
