Description

Technical Field

[0001] This utility model relates to the field of screw machine feeding technology, and in particular to a feeding bin for screw machines. Background Technology

[0002] A screw fastening machine is a small, automated machine for fastening screws. Its operating structure can generally be divided into two parts: a feeding section and an electric screwdriver section. The feeding section is responsible for screening and providing screws, while the electric screwdriver section is responsible for picking up and fastening the screws. The emergence of screw fastening machines has both improved work efficiency and reduced the intensity of manual labor.

[0003] The feed hopper for screw tightening machines is an important component. Its main function is to store and orderly supply screws, ensuring that the screw tightening machine can perform screw tightening operations continuously and stably. A well-designed and high-performance feed hopper can improve the production efficiency of screw tightening machines, reduce manual intervention, and lower production costs.

[0004] Chinese patent document CN214922144U discloses a feeding bin for a screw-making machine, including a feeding bin body, a rotating chamber rotatably mounted on the side of the feeding bin body, a guide plate inside the rotating chamber, a rotating rod rotatably mounted inside the feeding bin body, and a feeding plate fixedly mounted at the bottom end of the rotating rod. A discharge port is opened on the side of the feeding bin body away from the rotating chamber, and a linear guide rail runs through the discharge port. A storage trough is mounted on the linear guide rail and is located below the feeding plate. This patent document, by rotatably mounting a rotating chamber on the side of the feeding bin body, with a guide plate inside, allows screws from the feeding bin body to be guided into the storage trough by the rotation of the rotating chamber. The rotation of the rotating rod drives the feeding plate to rotate, thereby kicking out screws that are not evenly arranged in the storage trough, thus ensuring the uniformity of screw arrangement in the storage trough and preventing blockage of the machine outlet due to uneven arrangement during later discharge.

[0005] The aforementioned patent documents can avoid blockage at the machine outlet due to uneven arrangement during the later discharge process. However, they cannot stably transport screws of different sizes, which can easily cause blockage or uneven arrangement of screws that are too large or too small during the transport process, thus affecting the screw transport efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, a feeding bin for a screw feeding machine includes a feeding bin body 1. A feeding mechanism 2 is fixedly connected to the upper right end of the outer surface of the feeding bin body 1, which facilitates the feeding of screws. A conveying mechanism 3 is slidably connected to the upper right wall of the inner cavity of the feeding bin body 1, which conveys the screws. Guide mechanisms 4 are symmetrically fixedly connected to the front and rear sides of the middle of the bottom wall of the inner cavity of the feeding bin body 1, which guides the movement of the conveying mechanism 3. The left side of the conveying mechanism 3 is slidably connected to the upper part of the two guide mechanisms 4. A vibration cylinder 5 is installed and fixed in the middle of the bottom wall of the inner cavity of the feeding bin body 1, and the upper output end of the vibration cylinder 5 is rotatably connected to the lower part of the conveying mechanism 3. The left side of the conveying mechanism 3 is symmetrically fixed. The connection of the limiting mechanism 6 can limit the conveyed screws. Both limiting mechanisms 6 are fixedly installed on the left side with electric telescopic rods 7. The output ends of both electric telescopic rods 7 are fixedly connected with adjustment mechanisms 8, which can adjust the number of screws entering the inner cavity of the bearing frame 9. The lower left wall of the inner cavity of the feeding hopper 1 is fixedly connected to the bearing frame 9. The front left side of the outer surface of the bearing frame 9 is fixedly installed with a motor 10. The lower part of the inner cavity of the bearing frame 9 is fixedly installed with a conveyor belt 11, and the front left input end of the conveyor belt 11 is fixedly connected to the rear output end of the motor 10. The upper front and rear sides of the inner cavity of the bearing frame 9 are symmetrically fixedly connected with discharge mechanisms 12, which can realize the orderly discharge of screws.

[0025] For easier screw placement, please refer to... Figure 2 The feeding mechanism 2 includes a feeding sleeve 21. An expansion mask 22 is fixedly connected to the upper right side of the outer surface of the feeding sleeve 21, which can facilitate the feeding of screws through its larger opening and prevent them from scattering to the outside.

[0026] To guide the movement of the material conveying mechanism 3, see [reference needed]. Figure 2 The guide mechanism 4 includes a base plate 41. Fixed columns 42 are symmetrically fixedly connected to the upper surface of the outer surface of the base plate 41. Limiting grooves 43 are opened at the upper surface of the outer surfaces of the two fixed columns 42 that are close to each other, which can guide and limit the up and down movement of the conveyor plate 31.

[0027] To achieve the purpose of conveying screws, refer to... Figure 3The material conveying mechanism 3 includes a material conveying plate 31. Connecting blocks 1 32 are symmetrically fixedly connected to the front end and the right rear end of the outer surface of the material conveying plate 31. Guide blocks 1 33 are fixedly connected to the middle of the right end of the outer surface of the two connecting blocks 1 32. Connecting blocks 2 34 are symmetrically fixedly connected to the front end and the left rear end of the outer surface of the material conveying plate 31. Guide blocks 2 35 are fixedly connected to the middle of the left end and the right end of the outer surface of the two connecting blocks 2 34. They can cooperate with the guide blocks 1 33 to guide the movement of the material conveying plate 31 when vibration occurs. The two guide blocks 1 33 are slidably connected to the upper right wall of the inner cavity of the feeding bin 1. Several guide blocks 2 35 are slidably connected to the inner cavity of the corresponding limiting groove 1 43.

[0028] To achieve the purpose of limiting the movement of the conveyed screws, refer to... Figure 3 The limiting mechanism 6 includes a right-angle plate 61. The left and right walls of the lower inner cavity of the right-angle plate 61 are symmetrically provided with limiting grooves 62, which can limit the movement of the trapezoidal baffle 81. The outer surface of the right-angle plate 61 is fixedly connected to the inner surface of the conveying plate 31.

[0029] To achieve the goal of adjusting the number of screws entering the inner cavity of the bearing frame 9, refer to... Figure 3 The adjustment mechanism 8 includes a trapezoidal baffle 81. Guide blocks 3 82 are symmetrically fixedly connected to the left and right ends of the outer surface of the trapezoidal baffle 81, and the two guide blocks 3 82 are slidably connected to the inner cavity of the corresponding limiting groove 2 62.

[0030] When the screw size is small, the electric telescopic rod 7 is driven to push the trapezoidal baffle 81 outward, thereby making the output end opening on the left side of the conveyor plate 31 smaller, so that the screws can be discharged one by one from the left opening end of the conveyor plate 31.

[0031] To achieve the purpose of orderly arranging the screws, refer to... Figure 4 The material discharge mechanism 12 includes a step plate 121. A material discharge groove 122 is provided on the upper part of the outer surface of the step plate 121 near the middle of the inner cavity of the bearing frame 9. The side of the outer surface of the step plate 121 away from the middle of the inner cavity of the bearing frame 9 is fixedly connected to the inner surface of the bearing frame 9.

[0032] As the screws are discharged one by one from the lower opening of the conveyor plate 31 and fall into the right side of the inner cavity of the two discharge troughs 122, the threaded rod of the lower part of the screw has a smaller diameter. Therefore, the threaded rod part will fall into the gap between the two discharge troughs 122, and the upper part of the screw will be in the inner cavity of the two discharge troughs 122. At this time, the lower end of the threaded rod of the screw will contact the upper surface of the conveyor belt 11, so that the screw can be conveyed to the left in an orderly manner along the inner surface of the two discharge troughs 122.

[0033] It should be noted that the model of the vibration cylinder 5, the electric telescopic rod 7, and the motor 10 in this utility model are BVP-60S, BVP-60S, and yzs132s2-2. The specific installation methods, oil circuit connection methods, circuit connection methods, and control methods of the vibration cylinder 5, electric telescopic rod 7, and motor 10 are all conventional designs and will not be described in detail in this utility model.

[0034] The working principle of this utility model is as follows: First, a suitable number of screws of the same size are inserted into the inner cavity of the feeding sleeve 21. Under their own gravity, they will slide into the inner cavity of the conveying plate 31. At this time, the driving guide mechanism 4 is activated, causing the output end of the vibration cylinder 5 to drive the conveying plate 31 to vibrate. This causes the screws located on the bottom wall of the inner cavity of the conveying plate 31 to slide slowly downward under the vibration force. During this process, the vibrating conveying plate 31 slides with the right wall of the inner cavity of the feeding bin 1 through two guide blocks 33 and with the inner cavity of the corresponding limiting groove 43 through several guide blocks 35, until the screws in the inner cavity of the conveying plate 31 are discharged from the left opening end of the conveying plate 31 along the surface of the two right-angle plates 61. The screws inside the two discharge troughs 122 will slide along the inner cavity of the two discharge troughs 122. The bottom end of the threaded rod at the bottom will contact the upper surface of the conveyor belt 11. At this time, the conveyor belt 11 will start running under the drive of the motor 10, so that the screws in the inner cavity of the two discharge troughs 122 can slide to the left in an orderly manner. By driving the two electric telescopic rods 7, the corresponding trapezoidal baffles 81 can be pushed outward, thereby adjusting the size of the opening at the bottom of the conveyor plate 31. This allows screws of different sizes to be discharged one by one to the right side of the inner cavity of the two discharge troughs 122.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
