Description

Technical Field

[0001] This invention relates to the field of screw production equipment technology, and in particular to an oiling device for screw production. Background Technology

[0002] Screws are tools that utilize the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually tighten objects and machine parts. Screws play a vital role in industry; in fact, it could be said that as long as industry exists on Earth, the function of screws will remain important. Currently, screws are oiled according to different usage environment requirements before being weighed, packaged, and shipped.

[0003] In order to ensure that the screws are fully oiled while preventing contamination and reducing waste, existing screw oiling equipment usually uses a filtration structure to filter out and collect excess oil.

[0004] For example, Chinese Patent Publication No. CN218554575U discloses "an oiling device for screw production". Its receiving oil filter cylinder filters the oil from the screws, reducing the dripping of oil outside the oil collection tank, thereby reducing the generation of dirt on the oiling device and playing the role of oil recovery. However, in actual use, the screws after oil filtration still need to be manually removed or an additional material handling device needs to be added, which not only increases the operating cost of the equipment, but also further increases the production cost if an additional material handling device is added. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing an oiling device for screw production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an oiling device for screw production, including an oiling device, a rotating mechanism and a filter box. The rotating mechanism is rotatably mounted on the oiling device and fixedly connected to multiple filter boxes via multiple support plates. A filter screen is provided below each filter box, and one side of the filter screen is rotatably connected to the support plate.

[0008] A reset mechanism is provided between the filter screen and the support plate, and a discharge assembly for unloading is provided between the filter screen and the oiling device.

[0009] Furthermore, a connecting part is fixedly provided on one side of the filter screen plate, and the connecting part is rotatably connected to the support plate so that the filter screen plate rotates around the connecting part as the center.

[0010] Furthermore, the unloading assembly includes a protrusion fixedly disposed below the filter screen plate, and a stop bar fixedly disposed on the inner wall of the oiling device and cooperating with the protrusion.

[0011] Furthermore, the reset mechanism includes a sector gear rotatably mounted on a support plate, the connecting part is a transmission gear meshing with the sector gear, and the support plate is provided with a reset component that cooperates with the sector gear.

[0012] Furthermore, the reset assembly includes an L-shaped plate fixedly connected to the sector gear, and a U-shaped plate that cooperates with the L-shaped plate is fixedly disposed on the support plate, with a spring provided between the L-shaped plate and the U-shaped plate.

[0013] Furthermore, both the L-shaped plate and the U-shaped plate are provided with fixing posts for inserting springs.

[0014] Furthermore, a protective plate is fixedly installed at the lower end of the U-shaped plate.

[0015] Furthermore, each filter box is fixedly provided with a guide portion, the upper end of which is an inclined surface.

[0016] Furthermore, a material leakage port is provided between the lower end of the guide and the bottom of the filter box.

[0017] Furthermore, a through groove is provided on one side of the oiling device, and a conveying device that cooperates with the filter box is provided in the through groove.

[0018] The oiling equipment for screw production proposed in this invention has the following advantages:

[0019] In this invention, the unloading assembly cooperates with the filter screen plate so that when the filter box rotates to the preset position, the protrusion at its lower end contacts the stop bar, restricting the rotation of the filter screen plate so that it is misaligned with the filter box. Rotating around the connecting part as the center causes the screws inside the filter box to fall down, avoiding additional labor or new equipment costs, thereby reducing the cost of use.

[0020] Secondly, in this invention, when the protrusion contacts the baffle, the filter box will still rotate with the rotating mechanism, and the filter screen will rotate around the connecting part as the center until it separates from the baffle. Under the action of the reset mechanism, it will be reset, so that the filter box can be reused repeatedly. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-4 An oiling device for screw production includes an oiling device 1, a rotating mechanism 2, and a filter box 3. The rotating mechanism 2 is rotatably mounted on the oiling device 1 and is fixedly connected to multiple filter boxes 3 via multiple support plates 4. A filter screen plate 5 is provided below the filter box 3, and one side of the filter screen plate 5 is rotatably connected to the support plate 4.

[0028] A reset mechanism 6 is provided between the filter screen plate 5 and the support plate 4, and a discharge assembly 7 for unloading is provided between the filter screen plate 5 and the oiling device 1.

[0029] In this invention, in order to automatically remove the screws after filtering, a material unloading component 7 is provided between the filter screen plate 5 and the oiling device 1. When the filter box 3 rotates to a certain position, the material unloading component 7 will cause the filter screen plate 5 and the filter box 3 to be misaligned, and the screws in the filter box 3 will be poured out. The filter screen plate 5 will be reset by the reset mechanism 6, so as to realize the cyclic use of the filter box 3.

[0030] Furthermore, in this embodiment, a connecting part 8 is fixedly provided on one side of the filter screen plate 5. The connecting part 8 is rotatably connected to the support plate 4 so that the filter screen plate 5 rotates around the connecting part 8 as the center, and is misaligned with the filter box 3 to form a gap, so that the screw falls out from the gap to achieve automatic unloading.

[0031] Furthermore, in this embodiment, the unloading assembly 7 includes a protrusion 71 fixedly disposed below the filter screen plate 5, and a stop bar 72 fixedly disposed on the inner wall of the oiling device 1 and cooperating with the protrusion 71. When the filter box 3 rotates to the upper end of the stop bar 72, the protrusion 71 contacts the stop bar 72. As the filter box 3 continues to rotate, the filter screen plate 5 will rotate around the connecting part 8 as the center because the protrusion 71 is blocked. During this process, the protrusion 71 will gradually move toward the rotating mechanism 2 until it separates from the stop bar 72. In order to facilitate the movement of the protrusion 71, in some embodiments, the stop bar 72 can be set with an included angle greater than 90 degrees, preferably 135 degrees.

[0032] It should be noted that in some embodiments, the reset mechanism 6 includes a sector gear 61 rotatably mounted on the support plate 4, and the connecting part 8 is a transmission gear meshing with the sector gear 61. The support plate 4 is provided with a reset component that cooperates with the sector gear 61, so that when the filter screen plate 5 rotates around the connecting part 8, the connecting part 8 rotates accordingly and drives the sector gear 61 to rotate. When the filter screen plate 5 is no longer subjected to external force, the reset component resets the sector gear 61, the connecting part 8, and the filter screen plate 5.

[0033] In some embodiments, the reset assembly includes an L-shaped plate 62 fixedly connected to the sector gear 61, and a U-shaped plate 63 fixedly disposed on the support plate 4 to cooperate with the L-shaped plate 62. A spring 64 is provided between the L-shaped plate 62 and the U-shaped plate 63 so that when the filter screen plate 5 rotates around the connecting part 8, the connecting part 8 rotates accordingly and drives the sector gear 61 to rotate. When the sector gear 61 rotates, the L-shaped plate 62 will compress the spring 64 so that when the filter screen plate 5 is no longer subjected to external force, the spring 64 will have a tendency to reset, causing the sector gear 61 to rotate in the opposite direction, thereby driving the connecting part 8 and the filter screen plate 5 to rotate and reset.

[0034] In some embodiments, both the L-shaped plate 62 and the U-shaped plate 63 are provided with fixing posts 65 for inserting the spring 64 to prevent the spring 64 from falling off or popping out.

[0035] In some other embodiments, a protective plate 66 is fixedly provided at the lower end of the U-shaped plate 63 to prevent the spring 64 from falling off or popping out.

[0036] Furthermore, in one shoe embodiment, a guide part 31 is fixedly provided inside the filter box 3. The upper end of the guide part 31 is an inclined surface, which guides the screw after oiling, so that the oil falls down along the inclined surface.

[0037] In detail, in this embodiment, a discharge port 32 is provided between the lower end of the guide part 31 and the bottom of the filter box 3. When the filter screen 5 is opened due to obstruction, there will be a material discharge gap between it and the filter box 3. As the filter box 3 rotates, the gap gradually increases. When the protrusion 71 separates from the stop bar 72, the gap reaches its maximum. However, the filter screen 5 is still not completely separated from the filter box 3, resulting in some screws remaining on the filter screen 5. In order to solve this problem, a guide part 31 is provided in the filter box 3 to form a discharge port 32. The area of ​​the discharge port 32 is smaller than the area when the gap is at its maximum value. When the gap is at its maximum value, the discharge port 32 is completely contained within the gap, so that the screws all move down along the discharge port 32 without leaving any residue.

[0038] In some embodiments, in order to facilitate the conveying of the removed screws, a through groove is provided on one side of the oiling device 1, and a conveying device that cooperates with the filter box 3 is provided in the through groove. The conveying device can be a conveyor belt or the like.

[0039] Working method: During operation, the oiling device 1 applies oil to the screws. After oiling, the screws fall into the filter box 3 to filter the oil. The rotating mechanism 2 drives the filter box 3 to rotate, allowing the new filter box 3 to continue receiving material. This is existing technology and will not be elaborated further. When the rotating mechanism 2 moves the filter box 3 above the baffle 72, the protrusion 71 contacts the baffle 72. The rotating mechanism 2 continues to drive the filter box 3 to rotate, and the protrusion 71 contacts the baffle 72, causing the filter screen plate 5 to rotate around the connecting part 8 as the center, creating a gap with the filter box 3, allowing the screw to fall and unload material. The connecting part 8 rotates accordingly and drives the sector gear 61 to rotate. The L-shaped plate 62 compresses the spring 64. When the filter box 3 rotates until the protrusion 71 separates from the baffle 72, the spring 64 tends to reset, causing the sector gear 61 to rotate in the opposite direction, thereby driving the connecting part 8 and the filter screen plate 5 to rotate and reset, so that the filter box 3 can continue to receive material after unloading.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
