Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a feeding mechanism for screw fasteners. Background Technology

[0002] A screw is a type of fastener. Its main function is to connect two workpieces together and fasten them. During the processing, screws are fed by a feeding track mechanism. In actual use, screws need to be placed on the feeding track one by one and then transported by the feeding track. If the screws are not placed accurately, they may tip over, which can easily cause the conveying to get stuck.

[0003] The existing technology CN221215793U discloses a feeding track mechanism for screw processing, including a feeding frame. The feeding frame has transmission rollers installed inside, and a conveyor rail is provided on the outer side of the transmission rollers. A screw body is mounted on the top of each conveyor rail. A fixing plate is provided on one side of each end of the feeding frame, and a guide plate is fixed to the top of the fixing plate. Servo motors are installed on both sides of the rear end of the feeding frame. A pre-drilled slot is provided at the top of the inner side of the feeding frame, and a ball bearing is installed inside the pre-drilled slot. By placing the fixing plate at the front and rear ends of the feeding frame, and inserting a positioning bolt through the pre-drilled hole into the inside of the feeding frame, the fixing plate is fixed to the feeding frame, thus fixing the guide plate. Screw bodies can be placed sequentially into the inside of the feeding frame and transported by the conveyor rail. During placement, the inclined guide plate acts as a guide, accurately guiding the screw body into the inside of the feeding frame.

[0004] However, when the screw body is placed on the conveyor rail for conveying using the above method, the head of the screw body will be on the rolling ball at the top of the feeder. The rolling ball supports the screw body for conveying. However, since the distance between the top of the feeder and the conveyor rail is fixed, it can only feed screw bodies of fixed length, which has a limited range of applications.

[0023] This utility model provides a feeding mechanism for screw fasteners, including a motor 101 and a feeding assembly 102. The feeding assembly 102 includes two transmission rollers 103, a conveyor belt 104, and two guide components 105. The guide component 105 includes a feeding frame 106, a slider 107, a screw 108, a guide plate 109, multiple balls 110, a knob 112, and two stabilizing members 113. The stabilizing member 113 includes a bracket 114, a threaded post 115, an anti-slip plate 116, and a guide rod 117. The aforementioned solution can feed screws 118 of different lengths, thus improving its applicability.

[0024] In this specific embodiment, the conveyor belt 104 is sleeved on the sides of the two drive rollers 103; two guide components 105 are located on both sides of the conveyor belt 104, and each guide component 105 includes a feeding frame 106, a slider 107, a screw 108, a guide plate 109, and a plurality of balls 110; the feeding frame 106 is rotatably connected to the two drive rollers 103 and is located on the sides of the two drive rollers 103; the slider 107 is slidably connected to the feeding frame 106 and is located inside the feeding frame 106; the screw 108 and the feeding frame 109 are also connected. 6. A rotatable connection is made to the slider 107 and threadedly connected to it, and located on the side of the feeder 106; a guide plate 109 is fixedly connected to the slider 107 and located on top of the slider 107; the guide plate 109 has multiple receiving grooves 111, which are evenly distributed on the top of the guide plate 109; multiple balls 110 are respectively located in the multiple receiving grooves 111; the motor 101 is fixedly connected to the feeder 106, and the output end of the motor 101 is fixedly connected to the transmission roller 103 and located on the side of the feeder 106. When feeding the screw 118, which is used as a fastener, the screw 118 is placed on the conveyor belt 104 with its head positioned above the ball bearing 110. The motor 101 drives the transmission roller 103 to rotate, and the two transmission rollers 103 drive the conveyor belt 104 to rotate, thus conveying the screw 118. The ball bearing 110 can roll within the receiving groove 111, allowing the screw 118 to be smoothly conveyed. The inner side of the slider 107 is provided with a threaded groove that matches the screw 108. When feeding screws 118 of different lengths, the operator rotates the screw 108. The rotation of the screw 108 causes the slider 107 to move longitudinally along the feeding frame 106. The slider 107 drives the guide plate 109 to move longitudinally, thereby adjusting the height of the guide plate 109 and the ball bearings 110. According to the length of the screw 118 to be fed, the distance between the ball bearings 110 and the conveyor belt 104 is adjusted, thus accommodating screws 118 of different lengths and enabling feeding of screws 118 of different lengths, thereby improving the applicability.

[0025] The knob 112 is fixedly connected to the screw 108 and is located at the bottom of the screw 108. The operator can easily rotate the screw 108 by holding the knob 112.

[0026] Secondly, the two stabilizing members 113 are mirror-arranged on both sides of the guide plate 109. The two stabilizing members 113 can stabilize the position of the guide plate 109 and prevent the guide plate 109 from moving.

[0027] Meanwhile, the bracket 114 is fixedly connected to the guide plate 109 and is located on the side of the guide plate 109; the threaded post 115 is threadedly connected to the bracket 114 and passes through the bracket 114; the anti-slip plate 116 is rotatably connected to the threaded post 115 and is located on the side of the threaded post 115. The bracket 114 is used to support the threaded post 115. By rotating the threaded post 115, the threaded post 115 rotates on the bracket 114 and moves simultaneously. The threaded post 115 drives the anti-slip plate 116 to approach the feed rack 106 until the anti-slip plate 116 abuts against the feed rack 106. The anti-slip plate 116 can prevent the guide plate 109 from moving, thereby improving the stability of the guide plate 109.

[0028] Furthermore, the guide rod 117 is slidably connected to the bracket 114 and fixedly connected to the anti-slip plate 116, and is located on the side of the bracket 114. The guide rod 117 is used to guide the anti-slip plate 116, preventing the anti-slip plate 116 from rotating, thereby improving the stability of the guide plate 109.

[0029] When using this invention to feed screws 118 as fasteners, the screws 118 are placed on the conveyor belt 104, with the head of the screws 118 positioned above the balls 110. The motor 101 drives the transmission rollers 103 to rotate, and the two transmission rollers 103 drive the conveyor belt 104 to rotate, thus conveying the screws 118. The balls 110 can roll within the receiving groove 111, allowing the screws 118 to be smoothly conveyed. The inner side of the slider 107 is provided with a fitting that is compatible with the screw 108. The threaded groove allows for feeding screws 118 of different lengths. By rotating the screw 108, the operator moves the slider 107 longitudinally along the feeding frame 106. The slider 107 then moves the guide plate 109 longitudinally, allowing adjustment of the height of the guide plate 109 and the ball bearings 110. The distance between the ball bearings 110 and the conveyor belt 104 is adjusted according to the length of the screw 118 to be fed, thus accommodating screws 118 of different lengths and improving the applicability of the feed. After the guide plate 109 is positioned, the threaded post 115 is rotated, causing it to move while rotating on the bracket 114. The threaded post 115 drives the anti-slip plate 116 to approach the feeding rack 106 until the anti-slip plate 116 is pressed against the feeding rack 106. The anti-slip plate 116 can prevent the guide plate 109 from moving, thus improving the stability of the guide plate 109.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
