Description

Technical Field

[0001] The present invention relates to the field of screw production, and specifically to a screening and blanking device for screw production. Background Art

[0002] Screw production is a process involving multiple processes and strict quality control. Through cold heading forming, tapping and thread rolling, heat treatment, surface treatment, and quality inspection, etc., it can ensure the product quality and production efficiency of screw production. Affected by the production process during screw production, screws of different models and specifications are mixed, and a screening and blanking structure (vibrating feeding and multi-stage screening technology) needs to be used for screening.

[0003] Common screening and blanking devices for screw production usually use a vibrator for feeding and cooperate with multiple inclined sieves with different mesh hole diameters, which can achieve accurate screening and blanking. However, the vibrating screen relies on unidirectional linear or high-frequency vibration, resulting in material accumulation and an increase in the leakage rate of fine particles, affecting the screening accuracy.

[0004] Therefore, a screening and blanking device for screw production is proposed to solve the problems that the vibrating screen relies on unidirectional linear or high-frequency vibration, resulting in butt joints of screw materials and being easily stuck in the mesh holes of the filter screen, affecting the screening efficiency and accuracy.

Specific embodiments

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] During the process of screw screening and blanking, promoting the movement of screw materials through unidirectional linear or high-frequency vibration will increase the risk of screw materials getting stuck in the through holes, resulting in low screening and blanking efficiency.

[0026] Please refer to Figures 1-5The present embodiment provides a screening and unloading device for screw production, including a bottom plate 1, a bracket 2, a connecting gear 3 and a gear ring plate 5, wherein a first motor is arranged on one side of one connecting gear 3, two annular enclosure plates 8 are arranged on the inner side of the gear ring plate 5, a synchronization rod 4 is fixedly connected between the two opposite connecting gears 3, and the synchronization rod 4 increases the stability between the two relative brackets 2, and a support plate 6 is fixedly connected to the side opposite to the annular enclosure plate 8 of the gear ring plate 5, and the support plate 6 is rotatably connected to a spring telescopic rod 7 through a rotating shaft, and the spring telescopic rod 7 cooperates with the support plate 6 to connect the gear ring plate 5 and the annular enclosure A preliminary connection structure can be formed between the plates 8. A sieve drum 9 is fixedly connected between the two annular enclosures 8. A feeding port is provided on one side of the sieve drum 9. The feeding port is connected to the sieve drum 9 by rotating the rotating shaft. At the same time, a buckle is provided on the other side of the feeding port. The feeding port of the sieve drum 9 corresponds to the baffle 28, and the feeding can be realized by manually opening. The sieve drum 9 is connected to the annular enclosure 8 by screws, which can be easily disassembled and replaced. A connecting ring 14 is provided in the annular enclosure 8, and an elastic support rod 10 is provided between the two opposite brackets 2. The elastic support rod 10 includes a groove provided on the bracket 2, which cooperates with a fixed rod, a spring and a movable The column can cause the connecting plate 11 to move up and down in the middle position of the bracket 2, while the gear ring plate 5 remains stable. At this time, when the second motor drives the rotating rod 12 and the arc-shaped columnar protrusion 13 to contact the connecting ring 14, the annular enclosure 8 will vibrate longitudinally and transversely, and the gear ring plate 5 drives the annular enclosure 8 to rotate, which can make the rotation of the screen drum 9 present a composite movement. The screen drum 9 rotates counterclockwise, thereby realizing dynamic layered screening of screws of different sizes and promoting the screening and feeding efficiency of the screws. At the same time, when the screen drum 9 rotates, when the screw is knocked down and stuck in the screen hole area, it can be automatically pulled up by gravity when the screw gradually moves up. Falling off, one end of the elastic support rod 10 is fixedly connected with a connecting plate 11, one side of the connecting plate 11 is fixedly connected with a second motor, and the output end of the second motor is fixedly connected with a rotating rod 12, and the upper and lower sides of the rotating rod 12 are fixedly connected with arc-shaped columnar protrusions 13, and the arc-shaped columnar protrusions 13 correspond to the connecting ring 14. The annular enclosure 8 is rotatably connected with a rotating plate 15 through a bearing, and the rotating plate 15 is fixedly connected to the connecting plate 11, so it is convenient to feed stably and clean the screws with water. A material guide groove 16 is fixedly connected to one of the rotating plates 15, and the material guide groove 16 is fixedly connected to one of the connecting plates 11;

[0027] The toothed ring plate 5 is fixedly connected to one side opposite to the annular enclosure plate 8 with a fixed ring. The fixed rings are provided in several groups and correspond to each other. A telescopic spring 18 is fixedly connected between two opposite fixed rings. By providing multiple groups of telescopic springs 18, it is convenient to stably receive materials.

[0028] Arc-shaped clamping blocks are in contact with both sides of the telescopic spring 18. The arc-shaped clamping blocks are fixedly connected to the toothed ring plate 5 and the annular enclosing plate 8 respectively. A number of sieve hole areas are evenly arranged in the sieve cylinder 9. The sieve holes in the sieve hole areas are arranged in a beautiful array. Triangular plates 20 arranged at equal distances are provided between two adjacent sieve hole areas. The triangular plates 20 are fixedly connected to the inner side of the sieve cylinder 9. The outer side of the outermost sieve cylinder 9 is in contact with a support column 19. The support column 19 is fixedly connected to the annular enclosing plate 8. By evenly arranging the triangular plates 20 in the sieve cylinder 9, non-piled-up movement of the material can be generated, the contact frequency between the screw material and the sieve cylinder 9 can be increased, the slipping phenomenon can be reduced, and the rolling and sliding alternating movement of the screw material can be promoted;

[0029] A water pump 24 is fixedly connected to another connecting plate 11. The output end of the water pump 24 is fixedly connected to a conduit 25. Nozzles 26 are evenly fixedly connected to the bottom end of the conduit 25. The water pump 24 extracts external water source and can wash the screws through the conduit 25 and the nozzles 26.

[0030] Wherein, arc-shaped guide blocks 21 are fixedly connected to two sides of the connecting ring 14 away from each other. The arc-shaped guide blocks 21 correspond to the rotating rod 12. By arranging the arc-shaped guide blocks 21, the vibration effect is increased and the screening efficiency is improved.

[0031] Wherein, a buffer pad 22 is adhesively connected to the rotating rod 12. The buffer pad 22 is made of rubber material. The buffer pad 22 is in an arc-shaped structure and is in contact with the inner side of the connecting ring 14. By arranging the buffer pad 22, an energy release effect can be provided when the connecting ring 14 contacts the rotating rod 12.

[0032] Wherein, both ends of the connecting ring 14 are fixedly connected to the rotating plate 15. Buffer guide plates 23 are evenly fixedly connected to one side of the rotating plate 15. By arranging the buffer guide plates 23, when the sieve cylinder 9 rotates counterclockwise, the screw material rotates upward and part of it falls on the buffer guide plates 23 at the higher point. Through the multi-layer buffer guide plate 23 structure, the layering of the screw material can be realized and the screening effect can be improved.

[0033] Working principle: Screw materials are put in from the material guiding groove 16, then the first motor and the second motor are started. Then the first motor drives the connecting gear 3 and the toothed ring plate 5 to rotate, and the second motor drives the rotating rod 12 to rotate. The arc-shaped columnar protrusions 13 promote the up-and-down and lateral vibration of the annular enclosure 8. Under the action of the telescopic spring 18 and the spring telescopic rod 7, the vibration feeding effect can be promoted. At the same time, the continuous rotation of the sieve cylinder 9 can prevent the screw materials from getting stuck in the sieve holes in the sieve hole area. During the screening process, structures such as the arc-shaped guide block 21, the triangular plate 20, and the buffer guide plate 23 can increase the asymmetric movement track, promote dynamic stratification, and improve the screening efficiency. Then after the screening is completed, the motor is stopped, and the baffle 28 is controlled to be at the bottom side. At this time, the feeding port of the outer sieve cylinder 9 is first opened to facilitate the collection of the screw materials in the outer sieve cylinder 9. After the collection is completed, the feeding port of the inner sieve cylinder 9 can be opened for feeding, which can significantly improve the screening efficiency and prevent the screw materials from getting stuck in the sieve hole area.

[0034] The flexible connection between the toothed ring plate 5, the annular enclosure 8, and the sieve cylinder 9 will cause a fracture between the toothed ring plate 5 and the sieve cylinder 9, affecting the screening and feeding.

[0035] Please refer to Figures 1-5 , and further improvements have been made on the basis of Embodiment 1.

[0036] The spring telescopic rod 7 is composed of a fixed end and a moving end. A reinforcing ring 17 is fixedly connected to one side of the fixed end. The reinforcing ring 17 is made of metal material. By setting the reinforcing ring 17, the stiffness of the spring telescopic rod 7 is increased.

[0037] Convex strips are evenly fixedly connected to the moving end. The convex strips are movably inserted into the fixed end. By setting the convex strips, the contact surface between the fixed end and the moving end of the spring telescopic rod 7 is increased, and the stability of the spring telescopic rod 7 during telescoping is improved.

[0038] After screening, it is necessary to take the screws. When taking the materials, the toothed ring plate 5 will block the removal of the materials, affecting the feeding efficiency.

[0039] Please refer to Figure 1 and 5 , and further improvements have been made on the basis of Embodiment 1.

[0040] A guide ring 27 is fixedly connected to the inner side of the toothed ring plate 5. The cross-section of the guide ring 27 is in a triangular structure. By setting the guide ring 27, the materials can be on both sides of the guide ring 27 when the materials fall.

[0041] Both sides of the tooth ring plate 5 are fixedly connected with baffle plates 28. The baffle plates 28 are located above the bottom plate 1. The tooth ring plate 5 partially overlaps with the bracket 2. By arranging the baffle plates 28, when the baffle plates 28 are adjusted to be closest to the bottom plate 1 after screening is completed, the material discharge port can be opened, so that the material is located between the baffle plates 28 and the guide ring 27.

[0042] One side of the bracket 2 close to the connecting gear 3 is fixedly connected with a limiting rod 29. A supporting ball 30 is rotatably embedded on the limiting rod 29. By arranging the limiting rod 29 and the supporting ball 30, it is convenient to provide support for the tooth ring plate 5 and improve the stability of the connecting gear 3 driving the tooth ring plate 5 to rotate.

[0043] A recess is formed at the upper end of the bracket 2. The recess is in contact with the synchronous rod 4. A pressure strip is in contact with the upper side of the recess. A positioning rod is inserted into one side of the pressure strip and the positioning rod is threadedly connected to the bracket 2. By arranging the pressure strip, positioning rod and bracket 2 with adjustable height, the upper connecting gear 3 can be kept in contact with the tooth ring plate 5.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
