Description

Technical Field

[0001] The present application relates to the technical field of screw processing, and in particular to a screw feeding device. Background Art

[0002] Screw sleeve insulating particles have multiple functions in electrical systems, such as insulation protection, prevention of current loss, reduction of galvanic corrosion, and reduction of stray current interference. They are an important part of electrical systems.

[0003] In the prior art, insulating particles need to be sleeved on the neck of the screw, and several screws are sequentially mounted in a screw feeding unit. A material tray is provided at the discharge end of the screw feeding unit, and the screws fall directly into the material tray from the discharge end of the screw feeding unit. Subsequently, the neck of the screw is squeezed into the center hole of the insulating particle through a particle sleeve device, so that the end of the screw fits with the insulating particle, thereby realizing the screw particle sleeve process.

[0004] During the feeding and conveying process of the above-mentioned screws, when the screws fall directly into the material tray, if the screws do not fall completely into the material tray, the subsequent screws are likely to be blocked at the discharge end of the screw feeding unit, making it difficult to continue feeding the subsequent screws, affecting the mechanical rhythm of the overall system, thereby reducing the efficiency of the screws in pelletizing. Summary of the invention

[0005] In order to help solve the problem that the screws are easily blocked at the discharge end of the screw feeding unit during the feeding and conveying process, resulting in low efficiency of screw grain casing, the present application provides a screw feeding device, which adopts the following technical solution: it includes a base, the base is provided with a screw feeding unit for conveying screws, a plurality of screws are placed in the screw feeding unit in sequence, a material tray is arranged at the discharge end of the screw feeding unit, and the base is provided with a pushing component for pushing the screws at the output end of the screw feeding unit to the material tray.

[0006] Through the above technical scheme, when it is necessary to feed the screws, the screws are transported along the screw feeding unit to the discharge end of the screw feeding unit, the pushing component is started, and the screws at the output end of the screw feeding unit are pushed to the material tray. The pushing component is used to push the screws in sequence for feeding, thereby reducing the possibility of the screws being blocked in the screw feeding track due to the simultaneous transportation of multiple screws, thereby improving the transportation efficiency of the screw feeding and the efficiency of the screw grain collection.

[0007] In a specific possible implementation scheme, the screw feeding unit includes a vibration plate arranged on a base, a screw feeding track is provided at the output end of the vibration plate, the feeding plate is located at the output end of the screw feeding track, a plurality of screws are sequentially mounted in the screw feeding track, and a blocking component for controlling the opening and closing of the screw feeding track is provided on the base.

[0008] Through the above technical solution, the vibration plate is started, and the vibration plate arranges the screws in an orderly manner and transports them to the screw feeding track. The pushing component and the blocking component are used to transport the screws from the screw feeding track to the feeding plate in sequence, thereby improving the conveying efficiency of the screw feeding and reducing the possibility of the screws being blocked in the screw feeding track due to the simultaneous conveying of multiple screws.

[0009] In a specific feasible implementation scheme, the pushing assembly includes a mounting seat arranged on the base, the mounting seat is provided with two limit blocks, a guide rail is provided between the two limit blocks, the guide rail is communicated with the screw feeding rail, the mounting seat is provided with a pushing cylinder, the output end of the pushing cylinder is provided with a push rod, the push rod corresponds to the guide rail, and the guide rail corresponds to the material tray.

[0010] Through the above technical solution, the pushing cylinder is started to drive the push rod at the output end of the pushing cylinder to extend, and the guide track limits the movement direction of the push rod, so that the push rod slides along the guide track to push the screw to the material tray, reducing the possibility of screws being blocked in the screw feeding track due to the simultaneous conveying of multiple screws, thereby improving the conveying efficiency of the screw feeding.

[0011] In a specific possible implementation scheme, the blocking assembly includes a paddle rotatably connected to a mounting seat, an elastic seat is provided on the mounting seat, the paddle is located between the elastic seat and the output end of the screw feeding track, an elastic member is provided between the elastic seat and the paddle, and the screw is located between the push rod and the paddle.

[0012] Through the above technical solution, when the push rod is extended under the drive of the pushing cylinder, the push rod pushes the screw located between the guide track and the screw feeding track. The screw squeezes the paddle under the drive of the push rod to drive the paddle to rotate, so that the screw feeding track is in an open state. The push rod slides along the guide track to push the screw onto the material tray. Then the push rod retracts under the drive of the pushing cylinder, and the paddle is reset under the action of the elastic member, so that the screw feeding track is in a closed state.

[0013] In a specific possible implementation scheme, the elastic member is a torsion spring, a paddle shaft is provided on the mounting seat, the torsion spring is sleeved on the outer edge of the paddle shaft and is rotatably connected to the paddle shaft, one end of the torsion spring is provided on the paddle, and the other end is provided on the elastic seat.

[0014] Through the above technical solution, when the push rod is extended under the drive of the pushing cylinder, the push rod pushes the screw located between the guide track and the screw feeding track. The screw squeezes the paddle under the drive of the push rod to drive the paddle to rotate. At this time, the torsion spring is in a compressed state and the screw feeding track is in an open state; when the push rod is retracted under the drive of the pushing cylinder, the paddle loses the force of the push rod, and the torsion spring rebounds to drive the paddle to reset, so that the screw feeding track is in a closed state.

[0015] In a specific possible implementation manner, a stopper is provided on the mounting seat, and the paddle is located between the stopper and the mounting seat.

[0016] Through the above technical solution, the block reduces the interference of external equipment on the paddle, and at the same time reduces the interference of debris and dust on the movement of the elastic member, thereby playing a protective role.

[0017] In a specific possible implementation mode, a mounting bolt is passed through the stopper, a mounting groove matching the mounting bolt is opened on the mounting seat, and the mounting bolt is threadedly connected in the mounting groove.

[0018] Through the above technical solution, the operator can remove the stopper from the mounting seat by means of bolt disassembly, which is more flexible and convenient for subsequent replacement of stoppers of different models and sizes.

[0019] In a specific feasible implementation scheme, a first limit plate is provided between the two limit blocks, the guide rail is located between the first limit plate and the mounting seat, and a second limit plate is provided at the end of the push rod facing away from the pushing cylinder; when the pushing cylinder retracts, the first limit plate contacts the second limit plate.

[0020] Through the above technical solution, when the pushing cylinder is started and the push rod at the output end of the pushing cylinder is retracted, the push rod drives the second limit plate to contact the first limit plate, and the first limit plate limits the retraction of the push rod, thereby limiting the retraction stroke of the pushing cylinder, reducing the time required for the push rod to extend again to push the screw, and improving the feeding efficiency of the screw.

[0021] In a specific possible implementation manner, an arc groove matching the screw is formed on the surface of the second limiting plate facing away from the pushing cylinder.

[0022] Through the above technical solution, the arc groove reduces the possibility of the sharp edge of the second limit plate scratching the screw, and the arc groove is used to fit the screw for pushing, thereby improving the stability of the push rod when pushing the screw.

[0023] In a specific feasible implementation scheme, a first connecting block is provided at the output end of the pushing cylinder, a second connecting block is provided on the surface of the first connecting block facing away from the pushing cylinder, the first connecting block and the second connecting block constitute a T-block, a stabilizing block is provided at one end of the push rod facing the pushing cylinder, a connecting groove matching the T-block is provided on the stabilizing block, and the T-block is inserted into the connecting groove.

[0024] Through the above technical solution, the pushing cylinder is started to drive the T-block at the output end of the pushing cylinder to extend. Since the T-block is inserted into the connecting groove on the push rod, the push rod is extended. The connecting groove limits the position of the T-block. The T-block and the stabilizing block are used to improve the stability of the push rod during extension and retraction.

[0025] To sum up, the present application has at least the following beneficial technical effects: when it is necessary to feed the screws, the screws are transported along the screw feeding unit to the discharge end of the screw feeding unit, the pushing component is started, and the screws at the output end of the screw feeding unit are pushed to the feeding tray.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses a screw feeding device.

[0034] Reference Figure 1 and Figure 2The screw feeding device includes a base 1, on which a screw feeding unit for conveying screws is arranged, a plurality of screws are placed in the screw feeding unit in sequence, a material tray 2 is arranged at the discharge end of the screw feeding unit, and a pushing component for pushing the screws at the output end of the screw feeding unit to the material tray 2 is arranged on the base 1.

[0035] Therefore, when it is necessary to feed the screws, the screws are transported along the screw feeding unit to the discharge end of the screw feeding unit, the pushing component is started, and the screws at the output end of the screw feeding unit are pushed to the material tray 2. The method of using the pushing component to push the screws in sequence for feeding reduces the possibility of the screws being blocked at the discharge end of the screw feeding track 4 due to the simultaneous transport of multiple screws, thereby improving the screw feeding transport efficiency and the screw pelletizing efficiency. In the embodiment of the present application, the base 1 is arranged at an angle, which further facilitates the transport of the screws from the screw feeding unit to the material tray 2.

[0036] Reference Figure 1 and Figure 2 The screw feeding unit includes a vibration plate 3 arranged on a base 1, a screw feeding track 4 is arranged at the output end of the vibration plate 3, the feeding end of the screw feeding track 4 corresponds to the discharging end of the vibration plate 3, the feeding plate 2 is located at the output end of the screw feeding track 4, a plurality of screws are sequentially mounted in the screw feeding track 4, and a blocking component for controlling the opening and closing of the screw feeding track 4 is arranged on the base 1.

[0037] Therefore, the vibration plate 3 is started, and the vibration plate 3 arranges the screws neatly in sequence and conveys them to the screw feeding track 4. The pushing component and the blocking component are used to convey the screws from the screw feeding track 4 to the feeding plate 2 in sequence, thereby improving the conveying efficiency of the screw feeding and reducing the possibility of the screws being blocked in the screw feeding track 4 due to conveying multiple screws at the same time.

[0038] Reference Figure 3 and Figure 4 The pushing assembly includes a mounting seat 5 bolted to the base 1, two limit blocks 6 bolted to the mounting seat 5, a guide track 7 is arranged between the two limit blocks 6, the guide track 7 is communicated with the screw feeding track 4, a pushing cylinder 8 is bolted to the mounting seat 5, a push rod 9 is installed at the output end of the pushing cylinder 8, the push rod 9 corresponds to the guide track 7, and the guide track 7 corresponds to the material tray 2.

[0039] Therefore, the pushing cylinder 8 is started, driving the push rod 9 at the output end of the pushing cylinder 8 to extend, and the guide track 7 limits the movement direction of the push rod 9, so that the push rod 9 slides along the guide track 7 to push the screw to the material tray 2, reducing the possibility of the screws being blocked in the screw feeding track 4 due to the simultaneous transportation of multiple screws, thereby improving the transportation efficiency of the screw feeding.

[0040] Reference Figure 3 and Figure 4 The blocking component includes a paddle 10 rotatably connected to the mounting seat 5, and an elastic seat 11 is fixedly connected to the mounting seat 5. The paddle 10 is located between the elastic seat 11 and the output end of the screw feeding track 4. An elastic member is provided between the elastic seat 11 and the paddle 10, and the elastic member can be a torsion spring. A paddle shaft 12 is provided on the mounting seat 5, and the torsion spring is sleeved on the outer edge of the paddle shaft 12 and rotatably connected to the paddle shaft 12. One end of the torsion spring is arranged on the paddle 10, and the other end is arranged on the elastic seat 11. The screw is located between the push rod 9 and the paddle 10.

[0041] Therefore, when the push rod 9 is extended under the drive of the pushing cylinder 8, the push rod 9 pushes the screw located between the guide track 7 and the screw feeding track 4. The screw squeezes the paddle 10 under the drive of the push rod 9 to drive the paddle 10 to rotate. At this time, the torsion spring is in a compressed state, so that the screw feeding track 4 is in an open state, and the push rod 9 slides along the guide track 7 to push the screw onto the material tray 2; then the push rod 9 retracts under the drive of the pushing cylinder 8, the paddle 10 loses the force of the push rod 9, and the torsion spring rebounds to drive the paddle 10 to reset, so that the screw feeding track 4 is reset to a closed state.

[0042] Reference Figure 3 and Figure 4 , a rectangular block 14 is provided on the mounting seat 5, and the paddle 10 is located between the block 14 and the mounting seat 5. A mounting bolt is passed through the block 14, and a mounting groove 15 matching the size of the mounting bolt is provided on the mounting seat 5. The mounting bolt is threadedly connected in the mounting groove 15. The operator can remove the block 14 from the mounting seat 5 by disassembling the bolt, which is more flexible and convenient for subsequent replacement of blocks 14 of different models and sizes. Therefore, the block 14 located above the paddle 10 reduces the interference of external equipment on the paddle 10, and reduces the interference of debris and dust on the movement of the elastic member and the paddle 10, thereby protecting the paddle 10 and the elastic member below the block 14.

[0043] Reference Figure 4 and Figure 5 The output end of the pushing cylinder 8 is bolted to a first connecting block 19, and a second connecting block 20 is fixedly connected to the surface of the first connecting block 19 facing away from the pushing cylinder 8. The first connecting block 19 and the second connecting block 20 constitute a T-block 21. A stabilizing block 13 is provided at one end of the push rod 9 facing the pushing cylinder 8. A connecting groove 23 matching the size of the T-block 21 is opened on the stabilizing block 13, and the T-block 21 is inserted into the connecting groove 23.

[0044] Therefore, the pushing cylinder 8 is started, which drives the T-block 21 at the output end of the pushing cylinder 8 to extend. Since the T-block 21 is inserted into the connecting groove 23 on the push rod 9, the push rod 9 is extended. The connecting groove 23 limits the position of the T-block 21. The T-block 21 and the stabilizing block 13 are used to improve the stability of the push rod 9 during the extension and retraction process.

[0045] Reference Figure 4 and Figure 5 , a first limit plate 16 is bolted between the two limit blocks 6, the guide track 7 is located between the first limit plate 16 and the mounting seat 5, and the end of the push rod 9 away from the push cylinder 8 is fixedly connected to the second limit plate 17; when the push cylinder 8 retracts, the first limit plate 16 contacts the second limit plate 17. In the embodiment of the present application, an arc groove 18 matching the size of the screw is provided on the surface of the second limit plate 17 away from the push cylinder 8, and the arc groove 18 reduces the possibility of the sharp edge of the second limit plate 17 scratching the screw, and the arc groove 18 is used to fit the screw for pushing, thereby improving the stability of the push rod 9 when pushing the screw.

[0046] Therefore, when the pushing cylinder 8 is started and the push rod 9 at the output end of the pushing cylinder 8 is driven to retract, the push rod 9 drives the second limit plate 17 to contact the first limit plate 16, and the first limit plate 16 limits the retraction of the push rod 9, thereby limiting the retraction stroke of the pushing cylinder 8, reducing the time required for the push rod 9 to extend again to push the screw, and improving the feeding efficiency of the screw.

[0047] The implementation principle of the embodiment of the present application is as follows: when it is necessary to feed the screws, the vibration plate 3 is started, and the vibration plate 3 arranges the screws in order and transports them to the screw feeding track 4, and the screws in the screw feeding track 4 automatically slide to the output end of the screw feeding track 4, at which time the screws are located between the guide track 7 and the output end of the screw feeding track 4 and the screws are blocked by the paddle 10, and the screw feeding track 4 is in a closed state;

[0048] The push cylinder 8 is started to drive the push rod 9 at the output end of the push cylinder 8 to extend, and the push rod 9 pushes the screw. The screw squeezes the paddle 10 under the drive of the push rod 9 to drive the paddle 10 to rotate. At this time, the torsion spring is in a compressed state, so that the screw feeding track 4 is in an open state, and the push rod 9 continues to slide along the guide track 7 to push the screw to the material tray 2. At this time, the screw is located directly above the insulating particles and the two are coaxially arranged. Subsequently, the push rod 9 retracts under the drive of the push cylinder 8, and the paddle 10 loses the force of the push rod 9. The torsion spring rebounds and drives the paddle 10 to reset, so that the screw feeding track 4 is reset to a closed state. The paddle 10 blocks the screws subsequently transported in the screw feeding track 4, reducing the possibility of mutual interference between the screws during feeding; the screws are transported to the material tray in sequence by using the pushing assembly, which reduces the possibility of the screws being blocked at the discharge end of the screw feeding track 4 due to the simultaneous transportation of multiple screws, thereby improving the conveying efficiency of the screw feeding and the efficiency of the subsequent screw pelletizing process.
