Description

Technical Field

[0001] The utility model belongs to the field of rod body processing equipment, and particularly relates to an automatic shielding device for spraying a rod body. Background Art

[0002] During the processing of rods such as fishing rods and golf clubs, it is necessary to spray the rods to form a protective layer or decorative layer. In the existing rod spraying process, it is necessary to manually or use a dedicated tape wrapping device to wrap tape around the unpainted part of the rod. The wrapped tape plays a shielding and protective role during the spraying process, preventing the paint from being sprayed onto the parts that do not need to be painted. Although the rod can be protected by wrapping tape, there are the following defects: (1) Taping and spraying need to be completed on different equipment. After wrapping tape, the rod needs to be transported to the spraying equipment. After spraying, the tape needs to be torn off, which has low processing efficiency; (2) The tape wrapping accuracy will affect the effect and accuracy of spraying, which makes it difficult to meet the requirements of high-end rod processing. Utility Model Content

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] It should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. A person of ordinary skill in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] An automatic shielding device for spraying a rod body includes at least one set of shielding mechanisms. Setting up one set of shielding mechanisms can only spray one end of the rod body and cannot spray the middle section. In this embodiment, two sets of shielding mechanisms 100 and 200 distributed in a mirror image are set up, which can spray both ends and the middle section of the rod body, and has a wider range of applications.

[0025] The shielding mechanism includes a new tape supply mechanism 2, a waste tape winding mechanism 3, and a tape pressure roller 1 disposed between the new tape supply mechanism 2 and the waste tape winding mechanism 3. The tape on the new tape supply mechanism 2 passes under the tape pressure roller 1 and then transfers to the waste tape winding mechanism 3 for recovery. The rod body is shielded by the tape located between the tape pressure rollers 1. The number of the tape pressure rollers 1 is n, forming n-1 rod body shielding positions, where n ≥ 2. In this embodiment, there are three tape pressure rollers 1, forming two rod body shielding positions, which can shield two rod bodies at the same time. Two spray guns can simultaneously spray paint on two different rod bodies, thereby improving spraying efficiency.

[0026] The new tape supply mechanism 2 includes a tape support 21 for mounting a new tape roll 300 and a first connecting plate 24 for supporting the tape support 21. The main shaft of the tape support 21 is connected to the first connecting plate 24 via a bearing seat, and the first connecting plate 24 is connected to the first lifting mechanism 5a. A plurality of sensor plates 522 are distributed in a circular array on the back of the tape support 521, and a sensor 523 is provided on the first connecting plate 524. The tape roll is mounted on the tape support 521. When the waste tape winding mechanism 53 pulls the tape, it drives the tape support 521 and the sensor plate 522 to rotate together. The sensor 523 can sense the sensor plate 522. When the tape is exhausted, the tape support 521 and the sensor plate 522 stop rotating. The sensor 523 cannot sense the sensor plate 522, and the system prompts that the tape is exhausted, so that the tape can be replenished in time.

[0027] The waste tape winding mechanism 3 includes a taping rod 31 and a taping motor 32 that drives the taping rod 31. The taping rod 31 is connected to the main shaft of the taping motor 32 via a coupling. The taping motor 32 is connected to a second connecting plate 33, which is connected to the second lifting mechanism 5b. The taping motor 32 drives the taping rod 31 to rotate, winding the used tape around the taping rod 31 to form a waste tape roll 400.

[0028] A guide wheel 10 or a guide tube is provided between the tape wrapping rod 31 and the tape pressing wheel 1. The guide wheel 10 or the guide tube guides the tape coming out of the tape pressing wheel 1 and then wraps it around the tape wrapping rod 31, thereby ensuring that the tape under the tape pressing wheel 1 is in an unrolled state and making the tape wrapping rod 31 wrap more smoothly.

[0029] A waste box 9 is provided below the tape wrapping rod 31 , and the waste box 9 can collect paint dripping from the waste tape wrapped around the tape wrapping rod 31 .

[0030] A shielding box 11 is provided above the tape at the blocking position of the rod body. The shielding box 11 is detachably connected to the first connecting plate 24 and the second connecting plate 33. The shielding box 11 can collect paint sprayed by the spray gun, reduce the paint falling on the tape, and facilitate the winding and collection of waste tape.

[0031] The tape pressing wheel 1 is mounted on a first connecting plate 24 and a second connecting plate 33, which are connected by a limiting connecting plate 4. The tape pressing wheel 1 rises and falls with the first connecting plate 24 and the second connecting plate 33, thereby being synchronized with the new tape supply mechanism 2 and the waste tape winding mechanism 3.

[0032] In this embodiment, both the first and second lifting mechanisms 5a, 5b are linear modules, comprising a module slider 53, a lead screw 52, a module track 54, and a module motor 51. The module motor 51 rotates the lead screw 52, driving the module slider 53 on the lead screw 52 to move along the module track 54, thereby moving the first connecting plate 24 and the second connecting plate 33 connected to the module slider 53. The linear modules control the vertical movement of the new tape supply mechanism 2, the waste tape winding mechanism 3, and the tape pressure roller 1.

[0033] The first and second lifting mechanisms 5a, 5b move along the first and second translation rails 6, 7, respectively. The positions of the first and second lifting mechanisms 5a, 5b on the first and second translation rails 6, 7 can be adjusted based on the spraying position of the rod to meet the different spraying requirements of the rod. The first and second lifting mechanisms 5a, 5b utilize linear modules. The module fixing plate 55 of the linear module is connected to the shift slide 8, which moves along the first and second translation rails 6, 7.

[0034] During use, the automatic shielding device for pole spraying in the present invention adjusts the position of the shielding mechanism according to the shielding position of the pole. Specifically, the shielding mechanism is positioned on the first translation rail 6 and the second translation rail 7 so that the edge of the tape is aligned with the preset spraying end edge of the pole. After the pole is positioned below the tape, the first lifting mechanism 5a and the second lifting mechanism drive the new tape supply mechanism 2, the waste tape winding mechanism 3, and the tape pressure roller 1 to descend. Under the action of the tape pressure roller 1 and the pole, the tape forms a curved arc on both sides of the pole. The spray gun sprays paint from above the pole, and the tape provides a shielding and protective effect on the pole, ensuring that the paint is not sprayed on the shielded area of the pole. After spraying is completed, the first lifting mechanism 5a and the second lifting mechanism drive the new tape supply mechanism 2, the waste tape winding mechanism 3, and the tape pressure roller 1 to ascend. The waste tape winding mechanism 3 collects the waste tape, and the new tape in the shielded area is simultaneously in place, preparing for the next round of pole painting. The automatic shielding device for rod body spraying of the utility model has a reasonable structure and can improve the spraying efficiency and spraying accuracy when applied to the field of rod body spraying.

[0035] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
