[0021] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figures 1 to 4 The dual-hopper material distribution device provided by this utility model will now be described. The dual-hopper material distribution device includes a pressing worktable 13, a material distribution fixture, a material box 1, and a discharge pipe 10; the material box 1 has two material bins, each with a discharge port; the discharge pipe 10 has two parallel discharge channels, which are connected to the two discharge ports one by one; the lower end of the discharge pipe 10 is connected to the material distribution fixture, which is movably mounted on the pressing worktable 13. The material distribution fixture moves along the length of the pressing worktable 13, causing the lower discharge port of the discharge pipe 10 to cover the pressing groove 14 opened on the pressing worktable 13.

[0023] A dual-hopper material feeding device is installed on the pressing equipment and located on one side of the pressing molding machine; it is used to supply powder to the pressing molding machine. The material box 1 is located on one side of the pressing molding machine and has two hoppers, each used to hold different powders, such as diamond-containing cutting head powder and diamond-free welding layer powder. The feeding pipe 10 is fixed to the material feeding fixture and moves back and forth with the help of the fixture. When feeding is needed, the feeding pipe 10 moves to above the pressing trough 14 with the help of the material feeding fixture, and the powder in the two hoppers falls downwards into the pressing trough 14 through two separate feeding channels. After feeding is completed, the material feeding fixture moves the feeding pipe 10 backwards to make room, and the pressing head of the pressing molding machine squeezes the powder in the pressing trough 14, achieving cold pressing molding.

[0024] Compared with the prior art, the dual-material feeding device provided by this utility model moves the feeding pipe 10 above the pressing groove 14 through the feeding fixture, and realizes the simultaneous feeding of two kinds of powder through the two dropping channels of the feeding pipe 10; thus ensuring that the two kinds of powder can be pressed and formed at the same time, and improving the pressing efficiency.

[0025] In some possible embodiments, please refer to Figure 1 The discharge pipe 10 is connected to the material box 1 via two parallel hoses 2; the upper end of the hose 2 is connected to the discharge port of the material box, and the lower end of the hose 2 is connected to the discharge channel of the discharge pipe 10.

[0026] The lower ends of the two hoppers of the material bin 1 each have a discharge outlet, and a flexible hose 2 is connected to the outlet end. The lower end of the flexible hose 2 extends to the upper end of the two discharge channels of the discharge pipe 10. The flexible hose 2 can be made of plastic.

[0027] Valves are installed at the outlets of both hoppers. The hopper outlets are opened by switching the valves on and off before releasing the powder. Hose 2 is connected to the outlet of the valve; the valves can be manual or solenoid valves.

[0028] Specifically, the discharge pipe 10 includes an inclined rectangular pipe with a partition inside, which divides the inner cavity of the rectangular pipe into two discharge channels; the upper end of the rectangular pipe has a sealing plate and two connectors 3, which are installed side by side on the sealing plate and are connected to the two discharge channels one by one. The connectors 3 are used to connect the hose 2.

[0029] The feeding pipe 10 is a rectangular pipe structure, which is inclined. When the feeding pipe 10 is installed on the fabric placement fixture, the upper end of the feeding pipe 10 is connected to the hose 2 via the connector 3, and the lower end retains a rectangular outlet. The feeding pipe 10 includes a pipe shell and an internal partition. The internal partition divides the inner cavity of the pipe shell into two feeding channels, and the internal partition is welded and fixed to the pipe shell.

[0030] The connector 3 is a circular tube. One end of it is fixedly connected to the sealing plate and extends into the material discharge channel to communicate with the material discharge channel; the other end is located on the outside of the sealing plate and is used to connect and fix the flexible hose 2.

[0031] In some possible embodiments, please refer to Figures 2 to 3 The fabric fixture includes a translation base 7 and a mounting base 5; the translation base 7 is movably located at the upper end of the pressing table 13, and the mounting base 5 is fixed at the upper end of the translation base 7. The mounting base 5 has a degree of freedom in the width direction of the pressing table 13; the feed pipe 10 is connected to the mounting base 5.

[0032] The translation base 7 of the fabric fixture is located at the upper end of the pressing table 13 and is movable along the length of the pressing table 13. The upper end of the fabric fixture is fixed with a mounting base 5, which is used to support and fix the feeding pipe 10. When the mounting base 5 moves laterally, the feeding pipe 10 moves laterally to change the width ratio of the two powders in the pressing trough 14. When the translation base 7 moves along the length of the pressing table 13, it is used to carry the feeding pipe 10 to the top of the pressing trough 14 or move it out of the top of the pressing trough 14, switching between the feeding state and the pressing state.

[0033] Specifically, such as Figure 4 As shown, the front end of the mounting base 5 has a connecting notch 20 and multiple connecting bolts, and the upper part of the feed tube 10 has a connecting portion 4 extending outward. During installation, the feed tube 10 fits into the connecting notch 20, and the connecting portion 4 covers part of the structure of the mounting base 5. The connecting portion 4 is fixedly connected to the connecting bolts to limit the position of the feed tube 10. The mounting base 5 has a plate-like structure, and a weight-reducing hole 21 can be opened in the middle of the mounting base 5.

[0034] In some possible embodiments, please refer to Figures 2 to 3 The mounting base 5 and the translation base 7 have a positioning structure, which is used to limit the mounting base 5. The positioning structure includes a longitudinal positioning element that passes through the mounting base 5 and presses the mounting base 5 onto the translation base 7.

[0035] The positioning component is a positioning bolt 19. The rear end of the mounting base 5 has an elongated hole along the width direction of the pressing worktable 13. The positioning bolt 19 passes through the elongated hole and connects to the translation base 7. The nut at the upper end of the positioning bolt 19 rests against the mounting base 5.

[0036] The front end of the mounting base 5 has an elongated hole, and the front end of the mounting base 5 is fixed to the translation base 7 by a mounting bolt 18 passing through the elongated hole. The elongated hole at the front end of the mounting base 5 is parallel to the elongated hole at the rear end. When adjustment is required, first loosen the two mounting bolts 18 at the front end and the positioning bolt 19 at the rear end, then move the mounting base 5 laterally, and after the movement is completed, tighten the mounting bolts 18 at the front end and the positioning bolt 19 at the rear end again.

[0037] Mounting base 5 drives the feeding pipe 10 to move laterally, which can change the width ratio of the two powders in the pressing groove 14.

[0038] Mounting base 5 is mounted on base by means of a transverse moving assembly. The transverse moving assembly includes a fixing block 16 and an adjusting member 17. The fixing block 16 is located at the upper end of the translation base 7 and has a transverse threaded hole. The adjusting member 17 is arranged transversely and passes through the transverse threaded hole and is rotatably connected to mounting base 5.

[0039] The transverse component is located on the base. The fixing block 16 of the transverse component is located on one side of the mounting base 5 and is spaced apart from the mounting base 5. The fixing block 16 has bolt holes, the axis of which is consistent with the width direction of the pressure table 13. The bolt holes are located on one side of the mounting base 5. The adjusting member 17 passes through the bolt holes and is threaded into the inner wall of the bolt holes. One end of the adjusting member 17 is rotatably engaged with the mounting base 5. When it is necessary to adjust the mounting base 5, simply loosen the mounting bolt 18 and the positioning bolt 19, and then rotate the adjusting member 17. The adjusting member 17 moves relative to the fixing block 16, and at the same time, it drives the mounting base 5 to move laterally. Finally, when it moves to the desired position, tighten the mounting bolt 18 and the positioning bolt 19.

[0040] Optionally, the adjusting component 17 is a screw structure, with the nut of the adjusting component 17 located on the side of the fixing block 16 away from the mounting base 5. The rotation of the adjusting component 17 causes the mounting base 5 to move laterally. During adjustment, the nut of the adjusting component 17 can be turned with a wrench.

[0041] Optionally, the upper end of the translation base 7 has a strip-shaped limiting protrusion 6, the length direction of which is consistent with the width direction of the pressing worktable 13; the lower end of the mounting base 5 has a limiting groove that matches the limiting protrusion 6.

[0042] The limiting protrusion 6 and the limiting groove cooperate to further limit the movement direction of the mounting base 5, and facilitate the positioning and installation of the mounting bolt 18 and the positioning bolt 19.

[0043] The cross-section of the limiting protrusion 6 can be rectangular, and the two ends of the limiting protrusion 6 in the length direction extend to the two side edges of the translation base 7.

[0044] The translation base 7 is movable and positioned on the upper end of the pressure table 13 via a translation assembly. Specifically, a support base 8 is fixed to the upper end of the pressure table 13, and the upper end of the support base 8 has a translation assembly connected to the translation base 7. The support base 8 has two sets of upwardly protruding support portions, symmetrically arranged along the center line of the support base 8. Each set has two support portions, located at the front and rear ends of the support base 8, respectively.

[0045] The translation assembly includes two sliding rods 9 and a driving member 12. The two sliding rods 9 are respectively connected to two sets of support portions. The two ends of each sliding rod 9 are connected to two support portions of the same set, and the sliding rods 9 are horizontally arranged along the front-rear direction of the support base 8. A sliding block 15 is sleeved and connected to each of the two sliding rods 9, and the sliding block 15 is fixedly connected to the lower end face of the translation base 7. The driving member 12 is connected to the rear end of the translation base 7. When the driving member 12 moves forward, it drives the translation base 7 to move forward. While the translation base 7 moves, the sliding block 15 slides along the length of the sliding rod 9 to limit the direction of movement of the translation base 7.

[0046] The driving component 12 can be either a push rod or a connecting rod. When the driving component 12 is a connecting rod, the middle part of the connecting rod is hinged to the frame of the pressing worktable 13, and an auxiliary rod is hinged to the upper end of the connecting rod. The auxiliary rod is connected to the translation base 7, and the lower end of the connecting rod is hinged to the output end of the linear motor. The extension and retraction of the linear motor drives the connecting rod to rotate, which in turn drives the auxiliary rod to pull the translation base 7 to move.

[0047] When the drive component 12 is a push rod, the push rod is installed on the pressure table 13 along the length of the pressure table 13, and the free end of the push rod is connected to the translation base 7. The extension and retraction of the push rod drives the translation base 7 to move horizontally. Optionally, a connecting block 11 is provided at the rear end of the translation base 7, and the free end of the push rod is rotatably connected to the connecting block 11 by means of screws or other structures.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
