Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane foaming machines, in particular to a mixing device for a foaming machine with switchable directions. Background Art

[0002] Existing mixing devices for polyurethane foaming machines typically utilize a fixed vertical or horizontal mounting structure. While this design is simple, its angle and position are difficult to adjust, limiting its applicability to specific working environments and conditions. Alternatively, some mixing devices utilize electrically or hydraulically driven rotating mechanisms that can achieve certain angle adjustments. However, these mechanisms are complex, costly, and require specialized personnel for operation and maintenance.

[0003] Because the angle and position of existing foaming machine mixing devices are difficult to adjust, in actual operation, different mixing device brackets often need to be replaced to meet different production needs. This not only increases production costs but also reduces production efficiency. Secondly, during the flipping process of existing foaming machine mixing devices, the connecting hoses may twist and deform, affecting the transportation of raw materials and may even cause the hoses to rupture. Finally, the uneven distribution of the center of gravity of existing foaming machine mixing devices in different working states may cause the equipment to lose stability and affect production safety.

[0028] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention, but the present invention is not limited to the following embodiments.

[0029] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-9 As shown, a foaming machine mixing device with switchable direction includes a mixing head 1 and a fixed bracket 2 for fixing the mixing head 1. The fixed bracket 2 is rotatably connected to the main bracket 4 via a rotating shaft 3. The feed end of the mixing head 1 is connected to the fixed end of the rotating joint 6 via a connecting pipe 5, and the rotating end of the rotating joint 6 is connected to the feed pipeline. In specific use, the main bracket 4 is a component that plays a load-bearing role and has a relatively fixed position (the main bracket 4 can be connected to a ground support rod, a fixed frame, a suspension device or other fixing device), and serves as the main supporting component. As the mixing head 1 rotates, the direction of the discharge port 101 of the mixing head 1 changes accordingly, thereby realizing the switching of the foaming machine mixing device between horizontal feeding, vertical feeding or other feeding at any angle. The rotating joint 6, also known as a rotary joint, can ensure that when the mixing head 1 rotates, the feed pipeline connected to the rotating end of the rotating joint 6 always remains in the same direction, for example, in the vertical direction, and will not be twisted or deformed, thereby ensuring the stable operation of the feeding system. In the specific design, the number of connecting pipes 5 and rotating joints 6 is more than two, and unconnected pipelines can be left in actual use. Preferably, the connecting pipe 5 is a hard pipe and the feed pipeline is a hose; more preferably, the connecting pipe 5 is a steel pipeline.

[0031] In a specific embodiment of the present invention, a locking pin 201 is provided on the fixed bracket 2 for locking the rotation angle between the fixed bracket 2 and the main bracket 4. The locking pin 201 can lock the rotation angle of the fixed bracket 2 relative to the main bracket 4 by means of clamping locking or insertion locking. In the specific design, due to the gravity of the mixing head 1 itself, the horizontal and vertical fixation of the mixing head 1 can be achieved without providing the locking pin 201 or by means of binding, but providing the locking pin 201 can further increase the stability of the mixing head 1 in the operating state. In the specific design, if Figure 4 As shown, the fixing bracket 2 can be sleeved on the outside of the main bracket 4 , and a locking pin 201 can be provided on each side of the fixing bracket 2 .

[0032] In a specific embodiment of the present invention, at least two locking pin holes 401 for inserting the locking pins 201 are provided on the main bracket 4 . Figure 3 The two locking pin holes 401 in the mixing head 1 are sufficient to at least limit the mixing head 1 in the horizontal and vertical directions. In a specific design, three or more locking pin holes 401 can be provided to achieve the fixing of the mixing head 1 at a wider range of rotation angles. In actual use, after the direction of the foaming machine mixing device is adjusted, the locking pin 201 is inserted into the locking pin hole 401 to prevent the foaming machine mixing device from rotating relative to the main bracket 4.

[0033] In a specific embodiment of the present invention, the rotating shaft 3 is connected to the rotating shaft mounting hole 402 of the main bracket 4. The rotating shaft mounting hole 402 is located at the front of the main bracket 4, and the locking pin hole 401 is located proximal to the rotating shaft mounting hole 402. In a specific design, the rotating shaft 3 passes through the rotating shaft mounting hole 402 and is fixed to the fixed bracket 2 via an end plate. Preferably, a limit plate 403 is also provided at the bottom of the main bracket 4 to prevent excessive rotation of the mixing head 1.

[0034] In a specific embodiment of the present invention, the rear end of the main bracket 4 is connected to the rear end of the suspension bracket 8 through the back plate 7 .

[0035] In a specific embodiment of the present invention, an armrest 701 is installed on the rear side of the back plate 7. Preferably, there are two armrests 701, which are installed on the left and right sides of the rear side of the back plate 7, respectively, to facilitate the operator to hold the foaming machine mixing device for injection operation.

[0036] In a specific embodiment of the present invention, a cable fixing clamp 702 is installed on the back side of the back plate 7. The cable fixing clamp 702 is used to constrain and fix the electrical / sensor cables connected to the foaming machine mixing device. Preferably, the cable fixing clamp 702 is installed on the upper back side of the back plate 7.

[0037] In a specific embodiment of the present invention, the suspension bracket 8 is provided with a waist-shaped hole 801 movably connected to the bottom of the suspension member 9. The suspension member 9 is installed above the suspension bracket 8, and the suspension member 9 can be slid or tightened above the waist-shaped hole 801 by loosening or tightening the fastening bolt.

[0038] In a specific embodiment of the present invention, the top of the suspension member 9 is provided with two or more suspension holes 901, which are detachably connected to shackles 902. The shackles 902 can be installed in different suspension holes 901 of the suspension member 9. By adjusting the relative positions of the suspension member 9 and the shackles 902, the center of gravity of the foaming machine mixing device can be ensured to always be on the same vertical axis as the suspension point, thereby increasing the operational stability of the foaming machine mixing device.

[0039] In a specific embodiment of the present invention, the fixed end of the rotary joint 6 is fixed to the fixed plate 10 via a partition joint 601, and the fixed plate 10 is connected to the mixing head 1. During the switching process of the foaming machine mixing device, the rotatable end of the rotary joint 6 can ensure that the feed hose connected to the rotary joint 6 does not move significantly, thereby preventing the hose from twisting and deforming.

[0040] To sum up, the utility model can solve the problem that the angle and position of the mixing device of the polyurethane foaming machine are difficult to adjust, can solve the problem that the feeding hose connected to the mixing device of the foaming machine may be twisted and deformed during the flipping process, and can solve the problem of uneven distribution of the center of gravity of the mixing device of the foaming machine under different working conditions.
