[0002] Solar water heater bracket refers to the supporting element of the solar water tank, which is an important part of the solar water heater. The bracket design of the household solar water heater should be reasonable, and should have sufficient strength and rigidity to ensure sufficient load-bearing capacity. The water heater bracket is mainly a special bracket designed for placing, installing and fixing solar panels. It is generally made of aluminum alloy, stainless steel and other materials, and is processed into a specific bracket with required specifications and shapes through bending, welding, assembly and other means; The invention with publication number CN117181870B discloses a photovoltaic bracket bending processing device, which adopts a fan-shaped rotating block as a support at the bending part of the photovoltaic bracket, which can not only improve the stability during the bending process, but also avoid direct contact between the bottom end of the bracket and the groove wall, reduce the scratches and scratches of the material, improve the processing quality, add a width adjustment mechanism and an angle adjustment mechanism, and can better position and control the bending of the parts; The invention with the publication number CN117123655B discloses a solar photovoltaic bracket production bending device, wherein a connecting column is arranged at the bottom of a workbench, the connecting column and the fixing column are arranged concentrically, a locking component is arranged on the connecting column, and a positioning rod is arranged on the top of the locking component. When bending the bracket blank, the position of the positioning rod on the forced positioning component is pre-adjusted, and then the angle of the subsequent bracket blank bending can be positioned, so that the angle of each bending of the bracket blank can be kept consistent, thereby greatly improving the bending accuracy; However, the above-mentioned bending processing device for solar photovoltaic brackets still has the following problems during actual use: although the bending processing of the photovoltaic bracket is achieved through the bending parts of the device, as a processing device for the assembly line, this type of bending mechanism can only achieve the bending of a single bracket at a time. Before and after each processing, the staff needs to manually install and take it. Frequent installation work is likely to increase the risk of injury. At the same time, the single bending processing operation cannot improve work efficiency.

[0003] Therefore, we propose a self-feeding batch type solar water heater bracket bending machine to solve the above-mentioned problems. Summary of the invention

[0014] Preferably, the bending slide plate is driven down by the lifting threaded rod, and then the positioning flip plates on the left and right sides are flipped upwards so as to lift and limit the water heater bracket, and the rising of the bending slide plate drives the positioning flip plates on the left and right sides to flip downwards, and then the batch mechanism drives the bent water heater bracket to rotate downward to realize unloading.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-unloading batch type solar water heater bracket bending machine, through the batch mechanism above the carrying platform, locks the water heater bracket and drives it to rotate to the bending station, and the bracket is positioned by the positioning mechanism and the bending arc plate, so that the bracket rotated to the bottom can realize self-unloading, without manual auxiliary operation, and improves the processing efficiency. The specific contents are as follows: 1. The rotating sleeve and the locking sleeve are sleeved on the bracket, and the driving gear drives the driving gear ring and the rotating sleeve to rotate, and then the inner end of the sliding cone rod inside the locking sleeve is fitted by the resistance cam, so that it drives the sliding cone rod to move outward, and then the resistance inclined block connected to the outer end is moved to the outside of the locking sleeve, and then it is in contact with the inside of the bracket, so as to lock and position the brackets set at equal distances to prevent them from slipping during the following rotation; Furthermore, after the bracket is bent, it continues to be driven by the rotating sleeve and the locking sleeve to rotate and move toward the bottom of the bearing platform, and then the inner end of the sliding cone rod slides toward the inside of the locking sleeve due to the change in the shape of the interference cam, so that the interference bevel block set at the same angle slides toward the inside of the locking sleeve, and then breaks away from the interference lock with the bracket, so that the bracket rotated to the bottom can realize autonomous unloading, without the need for manual auxiliary operation, thereby improving processing efficiency; 2. During the rotation process, the lifting threaded rod first drives the meshing transmission shaft to rotate through the bevel gear set, and then the transmission shaft drives the positioning flip plate fixedly connected at the front end to flip upward, and then fits into the inside of the load-bearing platform. During this process, the positioning contact plate always contacts the rear end of the bracket to ensure that the bracket will not deviate after bending; At the same time, after the batch mechanism drives the bracket to rotate to the top of the load-bearing platform, the bracket presses the arc plate on the top of the positioning base to drive the arc plate to slide downward, so that the traction cable is in a relaxed state, and then the torsion spring is connected to the pressing side plate on the top of the positioning bracket and flips inward, thereby covering the left and right sides of the top surface of the bracket to prevent the bracket from being offset and misaligned during the subsequent bending process; 3. After the first batch of brackets are bent, the lifting threaded rod rotates in the opposite direction to drive the bending slide and the bending arc plate to rise, and drives the transmission shaft and the positioning flip plate to flip downward, so that the positioning base and the pressing side plate are disconnected from the bracket, and then the batch mechanism drives the bracket to flip downward to complete the unloading of the bracket after bending, and the bracket installed on the locking sleeve outside the rotating sleeve follows the rotation and moves again to the top surface of the load-bearing platform for the next bending work.
