DETAILED DESCRIPTION
[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example
[0028] See also Figure 1-4The utility model provides a technical solution: a catheter press material box, including a material box body 1, a feeding device 2 and a material guide 3, the material box body 1 and the material guide 3 are made of aluminum alloy, and the feeding device 2 is made of stainless steel; the material box body 1, the feeding device 2 and the material guide 3 are connected by bolts. A cavity for containing powder is formed inside the material box body 1, and the material box body 1 includes a material box side panel 11, a first material box baffle 12, a second material box baffle 13 and a partition 14 arranged in a symmetrical structure. The two ends of the first material box baffle 12 are connected to the inner walls on both sides of one end of the two material box side panels 11, and the two ends of the second material box baffle 13 are connected to the outer walls on both sides of the other end of the two material box side panels 11. The partition 14 is evenly distributed between the two material box side panels 11 to form a channel 111; a material box first pad 15 is connected to the bottom of the material box body 1, and through grooves 151 corresponding to the number of channels 111 are evenly opened on the first material box pad 15, and a sealing pad 16 matching the structure of the through grooves 151 is connected to the bottom of the first material box pad 15; a material box push plate 17 is connected to the front outer wall of the first material box baffle 12.
[0029] It should be noted that, in this embodiment, a first pad 15 of the material box is connected to the bottom of the material box body 1. Through grooves 151 corresponding to the number of channels are evenly opened on the first pad 15 of the material box. A sealing pad 16 matching the through groove structure is connected to the bottom of the first pad 15 of the material box. This double-layer structural design can enhance the sealing performance of the material box, prevent external air and moisture from entering the interior of the material box, and thus reduce the possibility of powder agglomeration due to moisture.
[0030] Furthermore, the material box body 1 and the material guide 2 are made of aluminum alloy. Aluminum alloy has good corrosion resistance and oxidation resistance. To a certain extent, it can reduce the oxidation reaction caused by moisture inside the material box and reduce the risk of powder getting wet. At the same time, aluminum alloy has good thermal conductivity, which can help dissipate heat inside the material box and prevent powder from getting damp and clumping due to excessive temperature.
[0031] Furthermore, the partitions 14 inside the cartridge body 1 are evenly distributed between the two cartridge side plates 11 to form channels, thereby ensuring that the powder is evenly distributed in each channel when entering the cartridge, thereby reducing the segregation of the powder components during transportation.
[0032] Furthermore, a material box push plate 17 is connected to the outer wall of the front side of the first material box baffle 12. The material box push plate 17 can push the material box body 1 when needed, so that it can better connect with other equipment or workstations, facilitate the transportation of powder and the movement of the material box. At the same time, the material box push plate 17 can also support and fix the material box body 1 to a certain extent, thereby increasing the stability of the material box.
[0033] The material box body 1, the feeding device 2 and the material guide 3 are connected by bolts. This connection method is simple and reliable, and is convenient for installation, disassembly and maintenance of the equipment. At the same time, the bolt connection can also ensure the relative position accuracy between the various components and ensure the working performance of the material box.
[0034] See also Figure 2 and 3 The feeding device 2 includes a feeding fixed plate 21 and a feeding pipe 22. The feeding fixed plate 21 is evenly penetrated with through holes 211. The feeding fixed plate 21 is connected to the end of the material box side plate 11 at the top of the second material box baffle 13. The number of the feeding pipe 22 matches the number of the through holes 211. One end of the feeding pipe 22 extends and is fixed inside the through hole 211. A butterfly valve switch is connected to the inside of each feeding pipe 22; the material guide part 3 includes a material guide spacer 31, which is distributed on the inner wall of the second material box baffle 13 between multiple through grooves 151 and the through holes 211; the material guide spacer 31 is arranged in a thirty-degree inclined structure.
[0035] It should be noted that, in this embodiment, the feed fixing plate 21 is uniformly provided with through holes 211, and the discharge pipes 22 match the number of the through holes 211 and extend and are fixed therein. Such a structure can ensure that the powder can pass through the discharge pipes more smoothly into the interior of the cartridge body 1. A butterfly valve switch is provided inside each discharge pipe 22 to control the flow of the powder as needed, thereby avoiding blockage or poor flow of the powder during the conveying process, thereby increasing the falling speed of the powder.
[0036] Furthermore, the guide blocks 31 are distributed on the inner wall of the second cartridge baffle 13 between the plurality of through slots 151 and the through holes 211 and are arranged in a 30-degree inclined structure. This inclined guide block 31 can guide the powder to flow smoothly into the through slots, reducing the accumulation and blockage of powder inside the cartridge, and further increasing the falling speed of the powder.
[0037] Furthermore, the mixed powder enters the discharge pipe 22 of the feeding device 2 through the external conveying system. The butterfly valve switch inside each discharge pipe 22 can adjust the flow rate of the powder as needed to ensure that the powder can enter the material box body 1 at a suitable speed and amount. When the butterfly valve switch is opened, the powder is subjected to the action of gravity in the discharge pipe 22 and begins to fall downward into the interior of the material box body 1. Since the through holes 211 on the feeding fixing plate 21 match the number of the discharge pipe 22, and one end of the discharge pipe 22 extends and is fixed inside the through hole 211, the powder can pass through the through hole 211 smoothly. Entering the cavity of the material box body 1, when the powder enters the material box body 1, it will first fall on the material guide spacer 31 of the material guide member 3. The material guide spacer 31 is arranged in a thirty-degree inclined structure. This inclined angle can guide the powder to flow smoothly to the bottom of the material box. The material guide spacer 31 is distributed on the inner wall of the second material box baffle 13 between multiple through grooves 151 and through holes 211. They can evenly distribute the powder to each channel 111 to avoid the accumulation or segregation of powder inside the material box. As the powder continues to enter the material box body 1, the amount of powder inside the material box gradually increases. When the press moves to a fixed filling state, the powder will fill the entire cavity of the material box body 1, and enter the mold cavity through the through groove 151 at the bottom of the material box for compression molding. During the entire powder conveying and filling process, the first pad 15 of the material box and the sealing pad 16 play a key sealing role. The first pad 15 of the material box is evenly penetrated with through grooves 151 corresponding to the number of channels 111, and the sealing pad 16 matches the structure of the through grooves 151 and can fit tightly together to prevent outside air and moisture from entering the interior of the material box, thereby preventing the powder from getting damp and clumping.
[0038] The working process of this utility model:
[0039] During use, the mixed powder enters the discharge pipe 22 of the feeding device 2 through the external conveying system. The butterfly valve switch inside each discharge pipe 22 can adjust the flow of powder as needed to ensure that the powder can enter the material box body 1 at a suitable speed and amount. When the butterfly valve switch is opened, the powder in the discharge pipe 22 is acted upon by gravity and begins to fall downward into the material box body 1. Since the number of through holes 211 on the feeding fixed plate 21 matches that of the discharge pipe 22, and one end of the discharge pipe 22 extends and is fixed inside the through hole 211, the powder can pass through the through hole 211 smoothly. Entering the cavity of the material box body 1, when the powder enters the material box body 1, it will first fall on the material guide spacer 31 of the material guide member 3. The material guide spacer 31 is arranged in a thirty-degree inclined structure. This inclined angle can guide the powder to flow smoothly to the bottom of the material box. The material guide spacer 31 is distributed on the inner wall of the second material box baffle 13 between multiple through grooves 151 and through holes 211. They can evenly distribute the powder to each channel 111 to avoid the accumulation or segregation of powder inside the material box. As the powder continues to enter the material box body 1, the amount of powder inside the material box gradually increases. When the press moves to a fixed filling state, the powder will fill the entire cavity of the material box body 1, and enter the mold cavity through the through groove 151 at the bottom of the material box for compression molding. During the entire powder conveying and filling process, the first pad 15 of the material box and the sealing pad 16 play a key sealing role. The first pad 15 of the material box is evenly penetrated with through grooves 151 corresponding to the number of channels 111, and the sealing pad 16 matches the structure of the through grooves 151 and can fit tightly together to prevent outside air and moisture from entering the interior of the material box, thereby preventing the powder from getting damp and clumping.
[0040] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
