Technical Field

[0001] The utility model relates to the technical field of dosing equipment welding, in particular to a hopper welding device for flocculant dosing equipment. Background Art

[0002] In the water treatment industry, flocculation and sedimentation are commonly used to purify sewage and sludge. Flocculants are added to the sewage or sludge to aggregate and precipitate solid particles in the sewage and denser impurity particles in the sludge, achieving the purpose of separation and purification. Since sewage or sludge is generally in a flowing state during water treatment, the flocculant addition process also needs to be continuous. Hopper-type dosing equipment used to store flocculants is an important component of the equipment.

[0003] When welding a hopper, the assembled hopper needs to be fixed to a clamping tool and the seam welded using a welding torch. The clamping plate on traditional welding equipment often uses bolts to secure the hopper. However, due to the fixed position of the bolt holes on the clamping plate, when assembling a wider hopper, the bolts on the clamping plate are often concentrated in one place. This makes the hopper prone to loosening when adjusting the welding angle, resulting in poor stability. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a hopper welding device for flocculant dosing equipment, including a welding robot arm 1 and a hopper assembly bracket, and the hopper assembly bracket is placed in front of the welding robot arm 1;

[0022] The hopper assembly bracket consists of two support bases 2, with an assembly frame 3 positioned between them. Two positioning plates 5 are located within the assembly frame 3. Clamps are located on the front of the positioning plates 5 to secure the hopper, and a spacing adjustment mechanism is located on the outside of the assembly frame 3 to adjust the distance between the two positioning plates 5. The hopper to be welded is secured directly in front of the positioning plates 5 using the two clamps, and a welding robot 1 welds the hopper joints. During the hopper assembly process, the spacing adjustment mechanism adjusts the distance between the two positioning plates 5, allowing the clamps on the positioning plates 5 to automatically adjust their spacing to accommodate hoppers of varying widths. This provides a wide range of applications and high reliability.

[0023] Assembly frame 3 is provided with rotating posts 4 at both ends. The end of rotating posts 4, remote from assembly frame 3, is rotatably connected to support base 2. Support base 2 includes an angle adjustment mechanism for controlling the rotation of rotating posts 4. Assembly frame 3 can rotate between the two support bases 2. Controlling the rotation of assembly frame 3 through the angle adjustment mechanism enables welding robot 1 to weld the back and bottom of the hopper, providing enhanced flexibility.

[0024] Regarding the angle adjustment mechanism: the angle adjustment mechanism includes a rotating shaft 17, a worm wheel 18, and a worm 19 provided in the support base 2. One end of the rotating shaft 17 passes through the support base 2 and is fixedly connected to one of the rotating columns 4. The worm wheel 18 is fixedly connected to the other end of the rotating shaft 17. The worm 19 is placed on one side of the worm wheel 18 and meshes with the worm wheel 18. A motor 20 is provided in the support base 2, and the output end of the motor 20 is fixedly connected to one end of the worm 19. The mounting end of the motor 20 is fixed to the inner side wall of the support base 2. When controlling the assembly frame 3 to flip, the motor 20 will control the rotation of the worm 19. During the rotation, the worm 19 will mesh with the worm wheel 18, thereby driving the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, the rotating column 4 and the assembly frame 3 will also flip accordingly.

[0025] The worm gear transmission has a self-locking property. When the worm 19 stops rotating, the worm 19 will limit the rotation of the assembly frame 3 and the rotating column 4 through the teeth engagement between the worm 19 and the worm wheel 18, so that the welding robot arm 1 can perform smooth welding.

[0026] Regarding the spacing adjustment mechanism: the spacing adjustment mechanism includes a second fixing frame 9 provided at the lower end of the assembly frame 3. A double-threaded screw 13 is provided within the second fixing frame 9. A first motor 12 is provided outside the second fixing frame 9. The output end of the first motor 12 is fixedly connected to the double-threaded screw 13. Two mating blocks 7 are provided on the outer sleeve of the double-threaded screw 13. The mating blocks 7 are threadedly connected to the double-threaded screw 13. The mating blocks 7 are slidably connected to a second slide groove 14 provided at the lower end of the assembly frame 3. The two mating blocks 7 are respectively fixedly connected to the lower ends of the two positioning plates 5. The outer sleeve of the double-threaded screw 13 has two threads, one in front and one in the back. The mating blocks 7, which are sleeved on the outer sleeve of the double-threaded screw 13, respectively mate with the two threads. When the first motor 12 drives the double-threaded screw 13 to rotate, the two mating blocks 7 move along the shaft of the double-threaded screw 13. Since the two threads have opposite thread directions, the two mating blocks 7 move synchronously in opposite directions. When the mating blocks 7 move, the positioning plates 5 also move accordingly, thereby completing the spacing adjustment of the two positioning plates 5.

[0027] The hopper is fixed in front of the two positioning plates 5 by two clamps. The use of double clamps for fixation has good reliability. The clamps include a clamping plate 15 provided on the front of the positioning plate 5. The lower end of the clamping plate 15 is fixedly connected to the positioning plate 5. The upper end of the clamping plate 15 is provided with a slot allowing the side of the hopper to be inserted. A bolt tightening member is provided on the front of the clamping plate 15 to prevent the hopper from detaching.

[0028] Specifically, the bolt tensioner includes a plurality of fastening bolts 16 mounted on the front of the clamping plate 15. Each fastening bolt 16 is evenly arranged along the length of the clamping plate 15. The fastening bolts 16 penetrate the clamping plate 15 and are threadedly connected to the clamping plate 15. When the hopper is fixed to the two positioning plates 5 for welding, one side wall of the hopper is inserted upside down into the slot provided at the upper ends of the two clamping plates 15. Then, the fastening bolt 16 is rotated to adjust the tension between the fastening bolt 16 and the inner wall of the hopper to complete the welding fixation of the hopper.

[0029] In order to improve the stability of the two positioning plates 5 when moving within the assembly frame 3, a first fixing frame 8 is provided at the upper end of the assembly frame 3. A limiting rod 10 is provided within the first fixing frame 8. Both ends of the limiting rod 10 are fixedly connected to the first fixing frame 8. Two sliders 6 are provided on the outer body of the limiting rod 10. The sliders 6 are slidably connected to the limiting rod 10. The sliders 6 are slidably connected to the first sliding groove 11 provided at the upper end of the assembly frame 3. The two sliders 6 are respectively fixedly connected to the upper ends of the two positioning plates 5. When the matching block 7 drives the positioning plate 5 to move from the lower end of the positioning plate 5, the slider 6 fixed to the upper end of the positioning plate 5 will also slide along the first sliding groove 11 and the limiting rod 10 at the same time. The upper and lower ends of the positioning plate 5 are both limited, and the positioning plate 5 will not deviate when the position is adjusted.

[0030] Working Principle: The hopper to be welded is secured to the front of a positioning plate 5 using two clamps. A welding robot 1 welds the hopper's seams. An angle adjustment mechanism controls the rotation of the assembly frame 3, enabling the welding robot 1 to weld the back and bottom of the hopper, providing enhanced flexibility. During the hopper clamping process, a spacing adjustment mechanism adjusts the distance between the two positioning plates 5. This allows the clamps on the plates 5 to automatically adjust their spacing to accommodate hoppers of varying widths, ensuring a wide range of applications and high reliability.
