Description

Technical Field

[0001] This utility model relates to the field of screw feeding technology, and in particular to a dustproof air-blowing type screw feeding misalignment mechanism. Background Technology

[0002] Air-blown screw feeding is a technology that uses positive pressure compressed air to transport screws from a storage device through a screw feeding tube to the tightening module head. The core of this feeding method lies in using the power of high-pressure airflow to ensure that the screws do not flip or jam during the feeding process, thereby achieving efficient and stable feeding.

[0003] In the prior art, after the screw enters the feeding device, its surface is in contact with the air. This causes the screw to pick up dust from the air. The dust adheres to the screw surface and may transfer to the product surface, resulting in an unclean product appearance and affecting the overall quality of the product. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a dustproof air-blowing screw feeding misalignment mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof air-blowing screw feeding misalignment mechanism includes a base, a groove on one side of the base, a feed inlet on one side of the base, the feed inlet being connected to the groove, a flow channel at the bottom of the base being connected to the groove, and a horizontal material transfer device installed on one side of the base for pushing the product entering from the feed inlet into the flow channel. The base has side plates on both sides and a top plate on the top. The side plates and top plate prevent dust from coming into contact with the products on the horizontal transfer device.

[0006] Preferably, the top plate includes a top plate body mounted on the top of the base, and an opening is provided on one side of the top plate body, in which an installation plate is installed.

[0007] Preferably, the feed inlet is provided with a stepped portion, the top of the stepped portion is higher than the height of the base, the mounting plate is positioned corresponding to the stepped portion, and the thickness of the mounting plate is less than the thickness of the top plate body, so that the height difference between the stepped portion and the base is eliminated by the thickness difference between the mounting plate and the top plate body.

[0008] Preferably, the horizontal material transfer device includes a cylinder disposed on one side of one of the side plates, a material transfer block slidably disposed in a groove, and a material transfer groove disposed on one side of the material transfer block. The driving end of the cylinder movably passes through the side plate and is connected to one side of the material transfer block. The material transfer groove is connected to the feed inlet, and the flow channel is connected to the material transfer groove.

[0009] Preferably, the top of the transfer block is provided with a moving groove, and a misalignment block is slidably installed in the moving groove. One side of the misalignment block is provided with a clamping groove for clamping the product that enters the limiting groove. The top of the misalignment block is provided with a horizontal moving component for moving the misalignment block.

[0010] Preferably, the clamping groove is U-shaped, and the top of the step portion is flush with the top of the misalignment block, which facilitates moving the product in the feed port into the clamping groove of the misalignment block.

[0011] Preferably, the horizontal moving component includes an inclined guide groove formed on the top plate body and a guide rod fixedly installed on the top of the misaligned block. The top of the guide rod extends into the guide groove, and the misaligned block is moved by the guidance of the guide groove.

[0014] Preferably, mounting holes are provided on both side plates, the top plate body, and the mounting plate to allow bolts to pass through the mounting holes and connect the side plates and the top plate body to the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the set base, can be installed on one side of the corresponding equipment, allowing the product to enter the feed inlet through the equipment, and then enter the horizontal transfer device in the groove through the feed inlet. The horizontal transfer device then moves the product to the top of the flow channel, allowing the product to enter the next process through the flow channel. After the product enters the base, the top plates set on both sides and the top, together with the equipment installed on one side, can make the base completely sealed. This can prevent the product entering the base from getting dusty and affecting the quality of the product. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1 to 5 A dustproof air-blowing screw feeding misalignment mechanism includes a base 1, a groove 2 on one side of the base 1, a feed inlet 3 on one side of the base 1, the feed inlet 3 being connected to the groove 2, a flow channel 4 connected to the groove 2 at the bottom of the base 1, and a horizontal material transfer device installed on one side of the base 1 for pushing the product entering from the feed inlet 3 into the flow channel 4. Side plates 5 are provided on both sides of the base 1, and a top plate is installed on the top of the base 1. The side plates 5 and the top plate prevent dust from coming into contact with the products on the horizontal transfer device.

[0020] When using this device, the base 1 can be installed on one side of the corresponding equipment, allowing the product to enter the feed inlet 3 through the equipment (e.g., a precision vibratory screw feeder of model VA-06-VBH). The product then enters the horizontal transfer device in the groove 2 through the feed inlet 3, and is then moved to the top of the flow channel 4 by the horizontal transfer device, allowing the product to enter the next process through the flow channel 4. After the product enters the base 1, the top plates on both sides and the top, along with the equipment installed on one side (which, through the discharge port of VA-06-VBH, can cooperate with the feed inlet 3 to form a seal), can make the base 1 completely sealed. This prevents the product entering the base 1 from being contaminated with dust, thus affecting the product quality.

[0021] Furthermore, the top plate includes a top plate body 6 installed on the top of the base 1. An opening is provided on one side of the top plate body 6, and an installation plate 7 is installed in the opening. Through the top plate body 6 and the installation plate 7, the top of the base 1 can be sealed to prevent dust from entering the groove 2, causing the product to absorb dust and affecting its quality.

[0022] Furthermore, a step 8 is provided inside the feed inlet 3. The top of the step 8 is higher than the height of the base 1. The mounting plate 7 is positioned corresponding to the step 8, and the thickness of the mounting plate 7 is less than the thickness of the top plate body 6. The difference in thickness between the mounting plate 7 and the top plate body 6 eliminates the height difference between the step 8 and the base 1, allowing the mounting plate 7 to be installed on the step 8 and the top plate body 6 to be installed on the base 1. This makes the tops of the mounting plate 7 and the top plate body 6 flush during installation, increasing the sealing effect. With the step 8, when the product enters the groove 2 through the feed inlet 3, the product is placed on the step 8 and moves along the step 8, allowing the product to enter the groove 2 in an orderly manner, increasing the feeding efficiency.

[0023] Furthermore, the horizontal material transfer device includes a cylinder 9 disposed on one side of one of the side plates 5, a material transfer block 10 slidably disposed in the groove 2, and a material transfer groove 11 disposed on one side of the material transfer block 10. The driving end of the cylinder 9 movably passes through the side plate 5 and is connected to one side of the material transfer block 10. The material transfer groove 11 is connected to the inlet 3, and the flow channel 4 is connected to the material transfer groove 11. A moving groove 12 is opened on the top of the material transfer block 10, and a misalignment block 13 is slidably installed in the moving groove 12. A clamping groove 14 is opened on one side of the misalignment block 13 for clamping the product entering the limiting groove. A horizontal moving component is provided on the top of the misalignment block 13 for moving the misalignment block 13. The clamping groove 14 is U-shaped, and the top of the step portion 8 is flush with the top of the misalignment block 13, which facilitates moving the product in the inlet 3 to the misalignment. Within the clamping groove 14 of block 13, the product can enter the transfer groove 11 through the step 8. Since the misaligned block 13 is flush with the step 8, the product can be directly confined within the transfer groove 11 by the clamping groove 14 when it enters. Then, the cylinder 9 pushes the transfer block 10 to move, thereby moving the product within the transfer groove 11. Simultaneously, the horizontal moving component pushes the misaligned block 13 backward. When the transfer groove 11 moves above the flow channel, the misaligned block 13 also moves outside the transfer groove 11, allowing the product to fall into the flow channel 4 through the guide of the transfer groove 11. The flow channel 4 then transports the product to the next process. In this way, only one product enters the flow channel 4 at a time, reducing the occurrence of product abnormalities in the flow channel 4, avoiding blockages, and ensuring smooth conveying.

[0024] Furthermore, the horizontal moving assembly includes an inclined guide groove 15 formed on the top plate body 6 and a guide rod 16 fixedly installed on the top of the misalignment block 13. The top of the guide rod 16 extends into the guide groove 15. The misalignment block 13 is moved by the guide of the guide groove 15. During the movement of the moving block, the guide rod 16 is moved backward by the guide of the guide groove 15, so as to move the misalignment block 13 connected to the guide rod 16 to the side away from the transfer groove 11. When the misalignment block 13 is completely moved out of the transfer groove 11, the clamping groove 14 will no longer clamp the product, and the transfer groove 11 moves above the flow channel 4, so that the product can fall into the flow channel 4.

[0025] Furthermore, a bracket 17 is installed above the top plate body 6, and a positioning detection component 18 is installed on the bracket 17 to detect whether the product is located in the limiting groove. Through the positioning detection component 18, it can be detected whether the product is located in the clamping groove 14 of the misalignment block 13. When a product is detected in the clamping groove 14, the cylinder 9 can be activated to push the transfer block 10 to move, so that the product falls into the flow channel 4.

[0026] The positioning detection component 18 is a proximity switch, which can detect objects without contact and has a fast response speed. The proximity switch is existing technology and will not be described in detail here.

[0027] Furthermore, the flow channel 4 includes a mounting head 19 installed at the bottom of the base 1 and a pipe 20 installed on the mounting head 19. One end of the pipe 20 passes through the mounting head 19 and is connected to the base 1 and the groove 2. The top of the pipe 20 corresponds to the position of the transfer groove 11. Through the mounting head 19, the pipe 20 can be installed below the base 1, and the position of the pipe 20 corresponds to the position of the transfer groove 11, which facilitates the product to fall into the pipe 20 through the transfer groove 11.

[0028] One side of the pipeline 20 can also be connected to an external vacuum generator via a connecting pipe. This external vacuum generator produces negative pressure at its vacuum port. This vacuum port is connected to the product flow channel 4 (pipeline 20) via a connecting pipe, thus creating a continuous negative pressure within the flow channel 4. Ambient air (carrying the freely falling screw) is drawn into the reserved cavity (connected to the vacuum port of the vacuum generator) from the inlet of the flow channel 4. Then, the operation of the vacuum generator is stopped, and air is released through a valve. The screw loses pressure and can be transported to a designated location (not shown in the figure) through the reserved cavity. It should be noted that using a vacuum generator to generate negative pressure within the product flow channel 4 for screw transport is not a technical feature of this invention, but rather an application of this device. Furthermore, the vacuum generator is existing technology and will not be elaborated upon further here.

[0029] Furthermore, mounting holes 21 are provided on both side plates 5, the top plate body 6, and the mounting plate 7, for bolts to pass through the mounting holes 21 to connect the side plates 5 and the top plate body 6 to the base 1.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
