Description

Technical Field

[0001] The utility model relates to the technical field of micro powder equipment, in particular to an anti-unhooking device for a micro powder machine collecting frame. Background Art

[0002] A micro powder machine is a device for manufacturing micro powders. It can process various raw materials through a series of processes such as crushing, pulverizing, and grading to finally obtain the desired micro powder products. In the prior art, the cylinder is connected to the cylinder coupling shaft, the cylinder coupling shaft passes through the limit block, a cone pin is installed on the cylinder coupling shaft, the cone pin is locked in the spring frame, so that the cylinder coupling shaft is connected to the spring frame, the spring sleeve is arranged on the spring frame, the spring frame passes through the capture frame, when the cylinder drives the pneumatic coupling shaft to move upward, the cylinder coupling shaft pulls the spring frame to move upward, the spring is compressed upward, and the spring frame pulls the capture frame to move upward, when the cylinder drives the cylinder coupling shaft to move downward, the cylinder coupling shaft pulls the spring frame to move downward, the spring recovers, and the spring frame moves downward to the limit block and is limited. The position where the capture frame is stuck stops its downward movement, and the limit block restricts the unlimited downward movement of the capture frame. In this process, when the material is captured by the capture bag and the material in the capture bag accumulates to a certain weight, the capture frame sinks under the action of gravity, and the limit frame sinks with the capture frame. At this time, there is a gap between the limit frame and the limit block. At this time, when the capture frame shakes, the cylinder moves quickly, but due to inertia, the capture frame does not move quickly in an instant. The spring frame may shake left and right because there is no limit. When the spring frame shakes left and right, the cone pin may fall off from the groove in the spring frame, causing the cylinder connecting shaft to be decoupled from the spring frame, thereby the cylinder connecting shaft to be decoupled from the capture frame, causing the capture frame to fall, resulting in safety accidents and quality accidents.

[0003] In summary, a micro powder machine capture frame anti-unhooking device is needed to prevent the cylinder connecting shaft from being unhooked from the spring frame when the material in the capture bag is too heavy, causing the capture frame to fall off. Summary of the invention

The spring frame may shake left and right because there is no limit. When the spring frame shakes left and right, the cone pin may fall off the groove in the spring frame, causing the cylinder coupling shaft to be decoupled from the spring frame, and then the cylinder coupling shaft is decoupled from the capture frame, leading to In order to solve the problem of the collecting frame falling off, the utility model provides an anti-unhooking device for the collecting frame of a micro powder machine.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1As shown, a micro powder machine capture frame anti-unhooking device, the micro powder machine capture frame anti-unhooking device includes a hopper 1, a feed port 2, a capture bag 3, a capture frame 4, a capture chamber 5, a cylinder 6, a cylinder connecting shaft 7, a guide positioning cylinder 8, a guide block 9, a guide cylinder 10, a limit frame 11, a limit block 12, a cone pin 13, a spring frame 14, a spring 15, an exhaust pipe 17, a ball groove 18, a ball screw 19 and a U-shaped groove 20. The hopper 1 is used to temporarily store materials after being crushed by the micro powder machine, the capture bag 3 is used to collect dust and materials sucked by the exhaust pipe, the capture frame 4 can lift the bottom of the capture bag 3 so that the opening of the capture bag 3 is downward, which is convenient for capturing dust and materials. The guide positioning cylinder 8, the guide block 9 and the guide cylinder 10 are used in combination. It can ensure that the capture frame 4 will not tilt when it is active, and at the same time it can bear the weight of the capture frame 4, avoiding that the weight of the entire capture frame 4 is borne entirely by the pneumatic coupling shaft 7, causing the pneumatic coupling shaft 7 to deform. The upper end of the spring frame 14 is cylindrical, and the diameter of the lower end is larger than that of the upper end. The spring 15 can be sleeved on the upper end of the spring frame 14. The ball groove 18 and the ball screw 19 are used in conjunction. The ball screw is composed of a spring, a steel ball, and a shell. The steel ball 191 can slide in the ball groove 18. The U-shaped groove 20 can lock the cone pin 13 in the spring frame 14, connect the pneumatic coupling shaft 7 and the spring frame 14, so that the pneumatic coupling shaft 7 and the capture frame 4 are connected. A discharge port 101 is provided at the bottom of the hopper 1. The material collected in the hopper 1 can be discharged through the discharge port 101. A fixing part 102 is provided on the upper side wall of the hopper 1. The fixing part 102 is used to fix the capture bag 3. A feed port 2 is provided on the side of the hopper 1 close to the upper side. The crushed material enters the hopper 1 from the feed port 2. The upper side of the hopper 1 is connected to the capture chamber 5. The hopper 1 and the capture chamber 5 form a closed space. The upper side of the capture chamber 5 is connected to the cylinder 6. One side of the capture chamber 5 is connected to the exhaust pipe 17. The top of the capture chamber 5 is connected to the guide positioning cylinder 8. The guide positioning cylinder 8 is connected to the guide cylinder 10 through the guide block 9. The guide cylinder 10 is fixedly connected to the capture frame 4. The guide cylinder 10 can move up and down on the guide positioning cylinder 8 under the action of the guide block 9. The guide cylinder 10 and the limit frame 11 are fixedly connected to the capture frame 4, and the limit frame 11 is installed in the guide cylinder 10. The guide positioning cylinder 8, the guide cylinder 10 and the limit frame 11 are on the same axis. The limit block 12 is movably arranged on the limit frame 11. The diameter of the limit block 12 is larger than the diameter of the limit frame 11, and the diameter of the limit block 12 is smaller than the diameter of the guide cylinder 10, so that the limit frame 11 can prevent the limit block 12 from falling infinitely. The cone pin 13 is installed at the position where the cylinder coupling shaft 7 is connected to the upper end of the spring frame 14. The cone pin 13 is locked in the spring frame 14 through the U-shaped groove 20. The spring frame 14 is provided with a cylinder coupling shaft slot 141 passing through the spring frame.The other end of the cylinder coupling shaft 7 passes through the cylinder coupling shaft slot 141 and is connected to the spring frame 14. The upper end of the spring frame 14 passes through the capture frame 4 and extends into the limit frame 11. Because the spring frame 14 passes through the capture frame 4, when the pneumatic coupling shaft 7 moves up and down, the capture frame 4 can be driven to move up and down by the spring frame 14. The spring 15 is sleeved on the upper end of the spring frame 14. The ball groove 18 is set at the end where the cylinder coupling shaft 7 is connected to the spring frame 14. The ball screw 19 is set on the inner walls on both sides of the lower end of the spring frame 14. The U-shaped groove 20 is set at the upper end of the spring frame 14. One end of the cylinder coupling shaft 7 is connected to the cylinder 6. The cylinder coupling The other end of the shaft 7 passes through the guide positioning cylinder 8 and the limit block 12 in sequence. The cylinder coupling shaft 7 is locked in the U-shaped groove 20 through the cone pin 13 and passes through the cylinder coupling shaft slot 141 to connect with the spring frame 14. The ball groove 18 and the ball screw 19 are embedded, and the steel ball 191 can only slide in the ball groove 18, so that the spring frame 14 can only move up and down, and cannot shake left and right, thereby limiting the left and right shaking of the spring frame 14, thereby avoiding the capture frame 4 from being unhooked during movement. The bottom of the capture bag 3 is hoisted on the capture frame 4, and the opening of the capture bag 3 is movably connected to the fixing piece 102. The capture bag 3 can be connected to the fixing piece 102 by means of a drawstring, a clamp, etc.

[0021] A spring limit block 16 is provided on one side of the capture frame 4 close to the capture bag 3. The diameter of the spring limit block 16 is larger than the diameter of the spring 15, and the diameter of the spring limit block 16 is smaller than the diameter of the limit frame 11, so that the spring 15 is limited within the range of the spring limit block 16 without deviation. The capture bag 3 is an anti-static filter bag, the ball groove 18 is a nearly semicircular groove, and the ball screw 19 is a steel ball 191 facing the cylinder coupling shaft groove 141. The steel ball 191 moves up and down in the nearly semicircular ball groove 18 and cannot deviate left and right, thereby limiting the spring frame 14 to only move up and down, and the spring frame 14 will not deviate left and right due to shaking, thereby preventing the cone pin 13 from being unhooked in the spring frame 14.

[0022] like Figure 2 , 3As shown in , 4, and 5, before the equipment is operated, the pneumatic coupling shaft 7 is inserted into the spring frame 14, one end A of the cone pin 13 coincides with A", and the other end B of the cone pin 13 coincides with B", and the spring frame 14 is rotated, and the cone pin 13 moves in the U-shaped groove 20 opened in the spring frame 14, so that one end A of the cone pin 13 moves from A" to A'" and coincides with A', and the other end B of the cone pin 13 moves from B" to B'" and coincides with B', and the cone pin 13 is locked in the spring frame 14. When the material in the capture bag 3 is heavier, the capture frame 4 sinks under the action of gravity, driving the limit frame 11 to sink. At this time, there is a gap between the limit frame 11 and the limit block 12. If the capture rack 4 is shaken at this time, the cylinder 6 moves quickly. Under the action of inertia, the capture rack 4 does not move quickly for a moment. Due to the left and right shaking of the spring frame 14, one end A of the cone pin 13 shakes from A' to A'" position, and the other end B of the cone pin 13 shakes from B' to B''' position. When the cylinder 6 drives the cylinder connecting shaft 7 to move upward quickly, one end A of the cone pin 13 is pulled upward from A''' to A" position, and the other end B of the cone pin 13 is pulled upward from B''' to B'' position, and the cone pin 13 is unhooked from the spring frame 14, thereby unhooking from the capture rack 4, causing the capture rack 4 to fall, resulting in safety accidents and quality accidents.

[0023] A nearly semicircular ball groove 18 is provided at one end of the cylinder coupling shaft 7, and two symmetrical ball screws 19 are provided near the bottom of the spring frame 14. When the cone pin 13 locks the spring frame 14, the ball groove 18 and the ball screw 19 are engaged, and the steel ball 191 moves up and down in the nearly semicircular ball groove 18, which can limit the spring frame 14 to move up and down only along the pneumatic coupling shaft 7 at the position where the ball groove 18 is provided, and cannot swing left and right, thereby preventing the cone pin 13 from being decoupled from the spring frame 14 due to the swinging of the spring frame 14 during the movement, thereby decoupling the capture frame 4.

[0024] According to the above process, the spring frame can be prevented from shaking left and right, so that the cone pin is dislocated and separated from the groove in the spring frame, thereby preventing the capture frame from falling.

[0025] In summary, the anti-unhooking device of the micro powder machine capture frame has a simple structure. A pair of nearly semicircular ball grooves are processed at the position where the pneumatic connecting shaft contacts the spring frame, and a pair of ball screws are installed at the position where the inside of the spring frame contacts the pneumatic connecting shaft. The ball grooves and the ball screws are interlocked with each other to play a limiting role, preventing the spring frame from shaking left and right, causing the cone pin to be dislocated from the groove in the spring frame, and preventing the capture frame from falling.

[0026] It should be noted that the above is only a preferred embodiment of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments. Without departing from the spirit or basic features of the utility model, the utility model can be implemented in other specific forms. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
