[0031] Reference Figure 1 The present invention aims to provide an embodiment of the housing structure of a mixer.
[0032] The present invention relates to a mixer housing structure, referring to... Figure 1 and Figure 2 It includes a first box 100 and a second box 110, which are welded together to form a whole. The first box 100 is used to install the motor 300, and the second box 110 is used to install the transmission assembly. The motor 300 provides rotational power to the transmission assembly. It should be noted that the motor 300 and the transmission assembly are connected by belt drive.
[0033] It is understood that this utility model, by setting up a first box 100 and a second box 110, and welding the first box 100 and the second box 110 to form the box structure of the mixer, replaces the traditional one-piece casting of cast iron, greatly reduces the weight of the box, reduces the difficulty of handling and dependence on lifting equipment, and improves assembly efficiency.
[0034] Among them, reference Figure 3 and Figure 4 The first box 100 includes multiple side plates 120, a first mounting plate 130 and a second mounting plate 140.

A bearing seat 180 is provided between the first connecting plate 160 and the second connecting plate 170. The transmission assembly has a transmission shaft 190 that matches the bearing seat 180. The transmission shaft 190 is arranged parallel to the output shaft of the motor 300. It should be noted that the transmission shaft 190 can provide rotational power for the mixing structure of the mixer.
[0036] It is understood that this utility model, by setting multiple side plates 120, a first mounting plate 130, a second mounting plate 140, a semi-enclosed plate 150, a first connecting plate 160, and a second connecting plate 170, can be made of sheet metal material and manufactured into a certain shape using laser cutting and bending processes. The multiple side plates 120, the first mounting plate 130, and the second mounting plate 140 are welded to form a first box 100, and the semi-enclosed plate 150, the first connecting plate 160, and the second connecting plate 170 are welded to form a second box 110. This significantly reduces complex cutting processes, simplifies manufacturing procedures, and reduces production costs and material waste.
[0037] In some embodiments of this utility model, reference is made to Figure 1 The bearing housing 180 has a cylindrical structure, and both the first connecting plate 160 and the second connecting plate 170 are provided with mounting holes 200 that match the bearing housing 180.
[0038] It is understandable that using a cylindrical bearing housing 180 to connect the first connecting plate 160 and the second connecting plate 170 helps to improve the strength of the second box 110 and reduce the occurrence of deformation of the second box 110. At the same time, the bearing housing 180 can effectively support the drive shaft 190 and ensure that the drive shaft 190 rotates smoothly.
[0039] In some embodiments of this utility model, reference is made to Figure 1 The outer radial surface of the bearing housing 180 is provided with an external thread and a locking nut 210 that engages with the external thread.

[0046] Understandably, the abutment edge 250 abuts against the flange plate 230, limiting the axial displacement of the bearing housing 180. This eliminates the need to use bolts to fix one end of the bearing housing 180, greatly saving the installation time of the bearing housing 180.
[0047] In some embodiments of this utility model, reference is made to Figure 5 A plurality of stiffening plates 260 are connected between the first connecting plate 160 and the second connecting plate 170, and the plurality of stiffening plates 260 are distributed along the circumference of the bearing seat 180.
[0048] Understandably, the stiffening ribs 260 are distributed around the bearing housing 180, which significantly enhances the bending stiffness of the connecting plate and reduces the impact of the drive shaft 190 vibration on the housing.
[0049] In some embodiments of this utility model, bearings are fitted at both ends of the drive shaft 190, and the bearings are installed inside the bearing housing 180.
[0050] Understandably, the bearing is installed in conjunction with the bearing housing 180 to facilitate standardized procurement and replacement, shorten the maintenance cycle, and reduce the wear of the bearing housing 180.
[0051] In some embodiments of this utility model, reference is made to Figure 3 There are two first mounting plates 130, which are arranged opposite to each other. One end of the motor 300 has a connecting seat 270. The two first mounting plates 130 support the connecting seat 270. The first mounting plates 130 and the connecting seat 270 are connected by locking bolts 280.
[0052] It should be noted that the first mounting plate 130 is provided with mounting screw holes, and the connecting seat 270 is provided with a waist-shaped hole. The waist-shaped hole accommodates the locking bolt 280. The locking bolt 280 engages with the mounting screw hole, thereby facilitating the adjustment of the position of the motor 300.
[0053] In some embodiments of this utility model, reference is made to Figure 2 One of the multiple side plates 120, the one closest to the bearing housing 180, is provided with an adjusting threaded hole and an adjusting bolt 290 that engages with the adjusting threaded hole. The end of the adjusting bolt 290 abuts against the connecting seat 270 to adjust the position of the motor 300.
[0054] Understandably, the design of the adjusting bolt 290 abutting against the connecting seat 270 allows for adjustment of the motor 300's mounting position, compensation for machining or assembly errors, ensuring the parallelism of the drive shaft 190, and adjustment of the belt tension.
