Description

Technical Field

[0001] The utility model relates to the technical field of ball pressing machines, in particular to an automatic ball pressing machine. Background Art

[0002] The ball press is mainly used to press powdered materials that are difficult to shape. It is characterized by high molding pressure, adjustable main engine speed, and a spiral feeding device. Since 2002, relevant institutes in the metallurgical industry have conducted scientific research and adopted high-pressure powder ball presses to press the powder out of the kiln into balls for smelting. Some foreign steel mills and my country's Baosteel and Ansteel have already used it.

[0003] For example, the authorization announcement number "CN219749009U" is named an automatic ball press. Although the spherical material on the baffle will gradually and slowly slide onto the output conveyor belt and then be output by the output conveyor belt, thereby avoiding the material from falling and being broken by a large impact, which greatly improves the molding success rate of the machine, the existing automatic ball press adopts a baffle that can extend to buffer the material pressed into balls to ensure the molding rate. However, the baffle is pushed out by a spring each time, and is driven by the extrusion roller inside the ball press and retracted into the extrusion roller under the friction and tight action with the guide plate for circulation. However, during the uninterrupted rotation of the extrusion roller, the end of the baffle will often contact and wear with the guide plate. Therefore, the baffle and guide plate that rub and wear against each other during the operation of the automatic ball press will produce a large working noise, and will also reduce the service life of the baffle, making the baffle easy to break or deform, thus affecting the poor use effect of the existing automatic ball press.

[0004] At the same time, the existing automatic ball press adopts the operation of pouring powdered material into the hopper at the top and pressing it into a ball through two extrusion rollers. However, the powdered material poured into the hopper lacks the operation process of screening and dehumidification. The unscreened powdered material is easily mixed with large pieces of metal residues. Therefore, during pressing, the residues with too large volume will affect the pressing effect. At the same time, if the water content of the powdered material poured into the hopper is too high, it will also cause the ball product after pressing to be not compact enough and easy to loosen, thus affecting the product quality of the automatic ball press. Utility Model Content

[0005] The utility model aims to solve the problems of poor use effect and reduced product quality of the existing automatic ball pressing machines, and proposes an automatic ball pressing machine.

[0018] The utility model provides an automatic ball press machine, which has the beneficial effect that when the air bag is compressed by the falling spherical product, the internal reset spring is squeezed to contract, and then when the falling spherical product is opposite to the discharge holes at both ends, it will slide to any direction on both sides under the action of the slope of the guide slope.

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] See also Figure 1-6 An automatic ball press machine includes a ball press machine body 1, a base 2 and a hopper 3. The ball press machine body 1 is fixedly installed above the base 2. A stable buffering structure 5 for ball pressing products is arranged inside the ball press machine body 1. The stable buffering structure 5 for ball pressing products includes a positioning seat 51, an air bag 52 and a guide slope 55. The positioning seat 51 is fixedly installed inside the ball press machine body 1. Two discharge holes 54 are fixedly provided on both sides above the positioning seat 51. Air bags 52 are fixedly installed on the inner sides of the two discharge holes 54. The air bags 52 are made of a deformable and soft rubber material. The air bags 52 can start the buffering function of the product pressed into a ball by using its own soft expansion performance.

[0029] When the airbag 52 is compressed by the falling spherical product, the internal return spring 53 will be squeezed to contract, and then until the falling spherical product is opposite to the discharge holes 54 at both ends, it will slide to any direction on both sides under the action of the slope of the guide slope 55. At this time, the return spring 53 loses its restriction and pushes the airbag 52 upward to return to its original position and continue to catch the next falling spherical product. The return spring 53 is fixedly installed inside the airbag 52, and the two guide slopes 55 are fixedly connected to the two sides of the positioning seat 51.

[0030] The interior of the ball press machine body 1 is provided with an automatic circulation ball pressing structure 6, which includes a motor 61, a ball pressing roller 63 and a rotating chamber 65. The two motors 61 are fixedly mounted on the outer wall of the ball press machine body 1. When selecting the motor 61, a motor model that meets the use requirements can be selected. The output shafts of the two motors 61 are fixedly connected to a rotating rod 62 through a reducer. Two ball pressing rollers 63 are fixedly sleeved on the outer sides of the two rotating rods 62. When the powdered material is poured into the hopper 3, the powdered material in the hopper 3 will be sieved and dehumidified and then slide into the two ball pressing rollers 63 below. The power supply is connected to start the motor 61, and the motor 6 1 will drive the rotating rod 62 to rotate, and the two rotating rods 62 rotating in opposite directions will drive the ball pressing rollers 63 to rotate in opposite directions, so that the ball pressing rollers 63 will squeeze the powdered material into a sphere through the relatively merged ball pressing grooves 64, and then the sphere-forming material is caught by the airbag 52 for buffering and then discharged. The outer walls of the two ball pressing rollers 63 are fixedly provided with a plurality of ball pressing grooves 64, and the rotating chamber 65 is fixedly provided inside the ball pressing machine body 1. The two ball pressing rollers 63 are rotatably connected to the inner side of the rotating chamber 65, and the two ball pressing rollers 63 are relatively rotatably arranged, and the plurality of ball pressing grooves 64 are movably connected to each other, and the lower ends of the plurality of ball pressing grooves 64 are arranged opposite to the top of the airbag 52;

[0031] After the powdered material is poured into the hopper 3, the powdered material in the hopper 3 will be screened and dehumidified and then slide down to the two ball pressing rollers 63 below. The power supply is connected to start the motor 61, and the motor 61 will drive the rotating rod 62 to rotate. The two rotating rods 62 rotate in opposite directions to drive the ball pressing rollers 63 to rotate in opposite directions. In this way, the ball pressing rollers 63 will squeeze the powdered material into a sphere through the relatively merged ball pressing grooves 64. The sphere-forming material is then received and buffered by the airbag 52 and discharged. The airbag 52 is made of a deformable and soft rubber material. The airbag 52 can use its own soft expansion performance to start the buffering function for the product pressed into a ball.

[0032] When the airbag 52 is compressed by the falling spherical product, the internal reset spring 53 will be squeezed to contract, and then until the falling spherical product is opposite to the discharge holes 54 at both ends, it will slide to any direction on both sides under the action of the slope of the guide slope 55. At this time, the reset spring 53 loses its restriction and pushes up the airbag 52 to reset and continue to catch the next falling spherical product. The airbag buffering and reset structure is used to replace the rotating baffle that is easily worn to perform the material discharge buffering operation, which reduces the noise during the friction of the baffle, and also reduces the wear and tear of the baffle, thereby improving the use effect of the automatic ball press machine.

[0033] See also Figure 1-6The hopper 3 is fixedly mounted on the top of the ball press body 1. A powder material screening and dehumidification structure 7 is arranged inside the hopper 3. The powder material screening and dehumidification structure 7 comprises a limit block 71, a screen 72 and a blower 74. Two blowers 74 are fixedly mounted on both sides of the outer wall of the hopper 3. Air supply pipes 75 are fixedly mounted on the ends of the two blowers 74. The blowers 74 belong to a mature prior art method. The outside air is sucked in by the blower 74 and then blown out through the air supply pipe 75 to dehumidify the metal powder material in the feeding process of the hopper 3 and reduce the water content in the metal powder material. The two limit blocks 71 are fixedly mounted above the inner wall of the hopper 3. The two limit blocks 7 1 is movably connected with a screen 72, which is made of a stainless steel metal mesh plate. The screen 72 is placed above the limit block 71 and can be lifted by a handle 73 for cleaning and replacement. The screen 72 will screen the metal powder material poured into the hopper 3 to reduce the situation where large pieces of metal residues are mixed into the material and cause the material to not be able to form a ball when pressed. Finally, the unloading plate 76 guides the fine metal powder material with low water content to fall into the two ball pressing rollers 63 for pressing into a ball. The top of the screen 72 is fixedly installed with a handle 73. The lower end of the hopper 3 is fixedly connected with two unloading plates 76, and the tops of the two unloading plates 76 are arranged opposite to the screen 72.

[0034] The outside air is sucked in by the blower 74 and then blown out through the air supply pipe 75 to dehumidify the metal powder material in the feeding process of the hopper 3, thereby reducing the water content in the metal powder material. The screen 72 is made of a stainless steel metal mesh plate. The screen 72 is placed above the limit block 71 and can be lifted up by the handle 73 for cleaning and replacement. The screen 72 will screen the metal powder material poured into the hopper 3 to reduce the large pieces of metal residue mixed into the material, which will cause the material to not be able to be balled during pressing. Finally, the discharge plate 76 guides the fine metal powder material with low water content to fall into the two ball pressing rollers 63 for pressing into balls, thereby improving the production quality of the automatic ball pressing machine.

[0035] See also Figure 1-6A ball pressing product discharge structure 8 is provided above the base 2. The ball pressing product discharge structure 8 includes a support frame 81, a discharge hole 82 and a cushion layer 84. Two support frames 81 are fixedly installed above the base 1. Two discharge holes 82 are fixedly provided on the inner sides of the two support frames 81. Two conveyor belts 83 are fixedly installed on the inner sides of the two support frames 81. Two cushion layers 84 are fixedly installed inside the ball pressing machine body 1. The front ends of the two cushion layers 84 are arranged opposite to the guide slope 55. The cushion layers 84 are made of sponge material and are blocked at the front ends of the two guide slopes 55. The guide slopes 55 will block the falling ball-shaped When the product is discharged, the spherical product will touch the cushion layer 84 to limit sliding and then fall directly to the bottom conveyor belt 83. The height of the conveyor belt 83 above the guide slope 55 is relatively small, and it is not easy to scatter the spherical product. The lower ends of the two cushion layers 84 are arranged opposite to the top of the conveyor belt 83. The outer wall of the ball press machine body 1 is fixedly installed with a controller 4, and the controller 4 is electrically connected to the motor 61 through a wire. The controller 4 adopts the existing computer control at this stage, and can use circuit wires to operate the start and stop of the conveyor belt 83 and the motor 61. The controller 4 is electrically connected to the conveyor belt 83 through a wire.

[0036] Working principle:

[0037] When using an automatic ball press to produce metal powder materials:

[0038] The ball pressing and buffer feeding structure of the automatic ball press:

[0039] When the powder material is poured into the hopper 3, the powder material in the hopper 3 will be screened and dehumidified and then slide down to the two ball pressing rollers 63 below. The power supply is connected to start the motor 61, and the motor 61 will drive the rotating rod 62 to rotate. The two rotating rods 62 rotate in opposite directions to drive the ball pressing rollers 63 to rotate in opposite directions, so that the ball pressing rollers 63 will squeeze the powder material into spheres through the relatively merged ball pressing grooves 64.

[0040] The airbag 52 is made of a deformable and soft rubber material. The airbag 52 can use its own soft expansion performance to start the buffering function for the product pressed into a ball. When the airbag 52 is compressed by the falling spherical product, it will squeeze the internal return spring 53 to shrink. Then, until the falling spherical product is opposite to the discharge holes 54 at both ends, it will slide to any direction on both sides under the action of the slope of the guide slope 55. At this time, the return spring 53 loses its restriction and pushes the airbag 52 upward to return to its original position and continue to catch the next falling spherical product.

[0041] Automatic ball press powder material screening and dehumidification structure:

[0042] The outside air is sucked in by the blower 74 and then blown out through the air supply pipe 75 to dehumidify the metal powder material in the feeding process in the hopper 3, thereby reducing the water content in the metal powder material. The screen 72 is made of a stainless steel metal mesh plate. The screen 72 is placed above the limit block 71 and can be lifted up by the handle 73 for cleaning and replacement. The screen 72 will screen the metal powder material poured into the hopper 3 to reduce the large pieces of metal residue mixed into the material, which will cause the material to fail to form a ball when pressed. Finally, the discharge plate 76 guides the fine metal powder material with low water content to fall into the two ball pressing rollers 63 for pressing into balls.

[0043] Automatic ball press machine ball product unloading and conveying structure:

[0044] The cushion layer 84 is made of sponge material and is placed at the front end of the two guide slopes 55. When the falling spherical products are discharged through the guide slopes 55, the spherical products will be restricted from sliding when they touch the cushion layer 84 and then fall directly to the top of the bottom conveyor belt 83. The height of the conveyor belt 83 from the guide slopes 55 is relatively small, and it is not easy to scatter the spherical products.
