Description

Technical Field

[0001] This utility model relates to the technical field of screw conveying devices, specifically a screw arrangement and conveying device with a limiting structure. Background Technology

[0002] A screw arranging and conveying device is an automated equipment used to neatly arrange and transport scattered screws to a designated location. It typically consists of a vibratory feeder, a feed inlet, a counter, a conveyor belt, and a control system. The vibratory feeder transports the screws to the feed inlet at a specific direction and speed. The feed inlet adjusts the angle and position of the screws as they enter. The counter monitors the number of screws in real time. The conveyor belt outputs the screws to the designated location, and the control system is responsible for overall coordination and precise control.

[0003] For example, the Chinese authorized patent CN215325122U, "An Automatic Screw Feeder with Vibrating Disc," includes a vibrating feeder and a control panel installed on the outer surface of the vibrating feeder. When the motor is turned on, the rotating shaft rotates. An elastic strip is fixedly installed on the outer surface of the rotating shaft. The elastic strip is located at the upper end of the assembly, and the lower end of the assembly is inclined at the upper end of the L-shaped plate. The elastic strip rotates counterclockwise, lifting the baffle and leaving a gap at the lower end of the baffle to facilitate the passage of a group of screws. Since the rear end of the baffle is connected to the limiting plate through a support rod, and the elastic strip has a certain elasticity, the elastic strip continues to rotate and can deform under the resistance of the support rod until it passes over the surface of the baffle. During the lifting of the baffle, the support rod drives the elastic element to be stretched, that is, when the baffle no longer receives the resistance of the elastic strip, it quickly returns to its original position.

[0004] While the existing technologies can achieve the arrangement and conveying of screws, the screw screening and conveying speed is slow, which makes it difficult to meet the requirements of high-efficiency screw production. Moreover, the limiting structure adopts a fixed structure, which makes it difficult to achieve efficient and accurate arrangement of screws of different specifications. Therefore, it does not meet the current needs. In this regard, we propose a screw arrangement and conveying device with a limiting structure. Utility Model Content

[0005] The purpose of this invention is to provide a screw arrangement and conveying device with a limiting structure to solve the problems mentioned in the background art, such as slow screw screening and conveying speed and inability to accurately arrange screws of different specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screw arrangement conveying device with a limiting structure, comprising a housing, a material receiving cylinder disposed inside the housing, a fixed seat disposed at the rear end of the material receiving cylinder, and the fixed seat being fixed to the housing by bolts, a roller installed inside the fixed seat, the roller being rotatably connected to the fixed seat, and the lower end of the material receiving cylinder communicating with the opening of the roller, annularly distributed arc-shaped plates disposed inside the roller, and the arc-shaped plates being inserted and fixed to the roller, a feeding plate disposed at the upper end of the inner cavity of the roller, and the feeding plate being fixed to the fixed seat by a connecting plate, a conveying mechanism disposed at the lower end of the feeding plate, and the conveying mechanism extending to the outside of the housing, and a sweeping mechanism disposed above the conveying mechanism.

[0007] Preferably, a first motor is fixedly installed at the rear end inside the housing, and the output shaft of the first motor is connected to the shaft of the roller via a coupling.

[0008] Preferably, the sweeping mechanism includes a rotating rod, which is rotatably mounted above the front end of the fixed base. A transmission gear is installed at one end of the rotating rod inside the housing, and a torsion spring is installed between the housing and the rotating rod. A transmission rod is installed below the end of the rotating rod inside the housing. A sector gear is fixedly installed on the outside of the transmission rod, and the sector gear meshes with the transmission gear. Pulleys are installed at one end of the transmission rod and on the shaft of the first motor, and the upper and lower pulleys are connected by a belt. A sweeping brush is installed above the rotating rod on the conveying mechanism.

[0009] Preferably, the conveying mechanism includes two limiting plates, which are slidably limited by a groove on the conveying mechanism. An adjusting mechanism is provided at the middle position of the bottom of the conveying mechanism. A double-threaded transmission rod is rotatably installed inside the adjusting mechanism. Sliding blocks are symmetrically installed on both sides of the double-threaded transmission rod. The inner threaded hole of the sliding block is threadedly connected to the double-threaded transmission rod, and the upper end of the sliding block is fixed to the bottom of the limiting plate. A second motor is installed on one side of the adjusting mechanism, and the output shaft of the second motor is fixed to the double-threaded transmission rod.

[0010] Preferably, the feeding plate is inclined downwards, the cross-section of the feeding plate is a V-shaped structure, and the front end of the feeding plate is provided with a conical groove.

[0011] Preferably, the conveying mechanism is inclined downwards, and vibration motors are installed on both sides of the bottom of the conveying mechanism.

[0012] Preferably, the material receiving cylinder has an inclined structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a roller-type conveying mechanism. When the first motor is activated, its output shaft drives the roller to rotate. A matching conveyor then feeds screws into the receiving cylinder. Due to the inclined design of the receiving cylinder, the screws enter the roller's arc-shaped plate. As the roller rotates, the arc-shaped plate moves the screws upwards. When the screw reaches its apex, it falls to the feeding plate under gravity. The feeding plate has a V-shaped cross-section, feeding the screws vertically into the conveying mechanism. When the screw's end diameter is smaller than the distance between the limiting plates, the screw can be inserted longitudinally between the two limiting plates. The inclined structure, combined with the vibrating motor, outputs qualified screws to the outside of the casing. If the screw's end diameter is larger than the distance between the limiting plates or it does not correctly enter the limiting plates, it is swept back into the receiving cylinder by a sweeping brush. This process repeats, arranging and conveying qualified screws. The automatic screening and recycling of unqualified screws reduces losses caused by improper manual operation or screw quality issues, thus lowering production costs.

[0015] 2. This utility model incorporates an automatic sweeping mechanism. During the operation of the first motor, its output shaft, driven by a pulley, rotates the transmission rod, which in turn rotates the external sector gear. When the sector gear meshes with the transmission gear, it drives the rotating rod to rotate in one direction, causing the sweeping brush to swing to one side. As the sector gear continues to rotate and disengages from the transmission gear, the torsion spring causes the rotating rod to reset in the other direction, causing the brush to swing to the other side. This process repeats continuously, causing the sweeping brush to swing frequently at the upper end of the conveying mechanism, sweeping screws that have not entered between the limiting plates back into the receiving cylinder. This ensures that only screws that meet the size and position requirements can pass smoothly through the conveying mechanism, while screws that do not meet the requirements are swept back in time. This helps to ensure product quality in subsequent processing or assembly processes and reduces the defect rate caused by screw problems.

[0016] 3. This utility model has a limiting plate spacing adjustment mechanism. By turning on the second motor, its output shaft drives the double threaded transmission rod to rotate. Under the friction with the sliding block, the rotational motion is converted into linear motion, causing the two sliding blocks to move towards each other, thereby realizing the adjustment of the spacing between the two limiting plates. By adjusting the spacing of the limiting plates, it can adapt to the arrangement and conveying requirements of screws of different specifications, and has strong versatility and flexibility.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a screw arrangement conveying device with a limiting structure, comprising a housing 1, an inner housing 9 with an inclined material receiving cylinder 9, a fixed seat 2 at the rear end of the material receiving cylinder 9, the fixed seat 2 being fixed to the housing 1 by bolts, a roller 3 installed inside the fixed seat 2, the roller 3 being rotatably connected to the fixed seat 2, and the lower end of the material receiving cylinder 9 communicating with the opening of the roller 3, annularly distributed arc plates 4 inside the roller 3, the arc plates 4 being inserted and fixed to the roller 3, a feeding plate 5 at the upper end of the inner cavity of the roller 3, the feeding plate 5 being fixed to the fixed seat 2 by a connecting plate, the feeding plate 5 being inclined downwards, the cross-section of the feeding plate 5 being a V-shaped structure, and the front end of the feeding plate 5 being provided with a conical groove, a conveying mechanism 6 at the lower end of the feeding plate 5, the conveying mechanism 6 extending to the outside of the housing 1, the conveying mechanism 6 being inclined downwards, a vibrating motor 8 installed on both sides of the bottom of the conveying mechanism 6, and a sweeping mechanism above the conveying mechanism 6.

[0025] In use, the screws are fed into the receiving cylinder 9 via a matching conveyor. Due to the inclined design of the receiving cylinder 9, the screws entering the receiving cylinder 9 will enter the arc plate 4 of the roller 3. As the roller 3 rotates, the arc plate 4 moves the screws upward. When the screws reach the top, they will fall to the feeding plate 5 under the action of gravity. The feeding plate 5 has a V-shaped cross-section, which feeds the screws into the conveying mechanism 6 in a straight position. When the diameter of the screw end is smaller than the spacing of the conveying mechanism 6, the screw can be inserted longitudinally into the conveying mechanism 6. Its inclined structure, together with the vibrating motor 8, outputs qualified screws to the outside of the outer casing 1. If the diameter of the screw end is larger than the spacing of the conveying mechanism 6 or does not enter the conveying mechanism 6 correctly, it will be swept back into the receiving cylinder 9 by the sweeping mechanism. This process is repeated to arrange and convey qualified screws.

[0026] Please see Figure 2 and Figure 4 The first motor 13 is fixedly installed at the rear end inside the outer casing 1. The output shaft of the first motor 13 is connected to the shaft of the roller 3 through a coupling. The sweeping mechanism includes a rotating rod 10, which is rotatably installed above the front end of the fixed base 2. A transmission gear 15 is installed at one end of the rotating rod 10 inside the outer casing 1, and a torsion spring 18 is installed between the outer casing 1 and the rotating rod 10. A transmission rod 16 is installed below one end of the rotating rod 10 inside the outer casing 1. A sector gear 17 is fixedly installed on the outside of the transmission rod 16, and the sector gear 17 is meshed with the transmission gear 15. A pulley is installed at one end of the transmission rod 16 and on the shaft of the first motor 13, and the upper and lower pulleys are connected by a belt 14. A sweeping brush 11 is installed above the rotating rod 10 on the conveying mechanism 6.

[0027] During the operation of the first motor 13, its output shaft drives the transmission rod 16 to rotate under the transmission of the pulley, thereby driving the external sector gear 17 to rotate. When the sector gear 17 meshes with the transmission gear 15, it will drive the rotating rod 10 to rotate in one direction, thereby realizing the oscillation of the sweeping brush 11 to one side. As the sector gear 17 continues to rotate, after it loses meshing with the transmission gear 15, it will drive the rotating rod 10 to reset in the other direction under the action of the torsion spring 18, realizing the oscillation of the sweeping brush 11 to the other side. This process is repeated, causing the sweeping brush 11 to oscillate at a high frequency at the upper end of the conveying mechanism 6, sweeping the screws that have not entered between the limit plates 7 back into the receiving cylinder 9.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5The conveying mechanism 6 includes two limiting plates 7, which slide and limit the movement of the limiting plates 7 via grooves on the conveying mechanism 6. An adjusting mechanism 12 is provided at the middle position of the bottom of the conveying mechanism 6. A double-threaded transmission rod 19 is rotatably installed inside the adjusting mechanism 12. Sliding blocks 20 are symmetrically installed on both sides of the double-threaded transmission rod 19. The inner threaded hole of the sliding block 20 is connected to the double-threaded transmission rod 19 by threads, and the upper end of the sliding block 20 is fixed to the bottom of the limiting plate 7. A second motor 21 is installed on one side of the adjusting mechanism 12, and the output shaft of the second motor 21 is fixed to the double-threaded transmission rod 19. By turning on the second motor 21, its output shaft drives the double-threaded transmission rod 19 to rotate. Under the friction with the sliding block 20, the rotational motion is converted into linear motion, causing the two sliding blocks 20 to move towards each other, thereby realizing the adjustment of the distance between the two limiting plates 7. By adjusting the distance between the limiting plates 7, it can adapt to the arrangement and conveying requirements of screws of different specifications, and has strong versatility and flexibility.
