Description

Technical Field

[0001] This utility model relates to the field of purlin production technology, specifically a deburring device for purlin production. Background Technology

[0002] A purlin is a horizontal roof beam perpendicular to the roof truss or rafters, used to support the rafters or roofing material. Purlins are transversely bending members (usually bi-directional bending) and are generally designed as single-span simply supported purlins. Common purlin types include solid-web and light steel truss types. Purlins are typically made of wood or steel. Their function is to connect and support beams to walls, enhancing the stability of the building. Purlins bear the weight of the entire building; they are fixed to the walls, and beams can then be placed on the purlins. The purlins support the weight of the entire building by supporting the beams, and also bear the weight of the interior and exterior walls. Purlins are an important component of a building, undertaking multiple functions such as fixing, supporting, and connecting. Their importance cannot be ignored; they directly relate to the stability and safety of the building. Before purlins are used in construction, they need to be deburred to ensure they meet the requirements for use.

[0003] Existing deburring devices are inefficient when used because the purlins are too long and require clamps to hold them before grinding. In addition, the clamps are too large and have high manufacturing costs. Furthermore, manually pushing the purlins for deburring is not only inefficient but also poses a significant risk.

[0004] Based on this, a deburring device for purlin production is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide a deburring device for purlin production, so as to solve the problem in the background art that the efficiency of grinding is relatively low when the purlin is too long and is held by a clamp.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A deburring device for purlin production includes a workbench. A collection groove is provided at the center of the top of the workbench. First mounting grooves are provided on the top of the workbench and on both sides of the collection groove.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, a deburring device for purlin production includes a workbench 1. A collection groove 2 is provided at the center of the top of the workbench 1. First mounting grooves 3 are provided on the top of the workbench 1 and on both sides of the collection groove 2. Second mounting grooves 4 are provided on the top of the workbench 1 and on one side of the two first mounting grooves 3. Guide rollers 5 are rotatably mounted inside the collection groove 2 and inside the two second mounting grooves 4 via bearings. A fixing frame 6 is provided on the top of the workbench 1 and directly above the collection groove 2. A hydraulic cylinder 7 is fixedly mounted on the top of the fixing frame 6.

[0028] The output end of the hydraulic cylinder 7 is equipped with a grinding mechanism, the interior of the first mounting groove 3 is equipped with a drive mechanism 8, the exterior of the drive mechanism 8 is equipped with four conveying mechanisms 9, and a side door 15 is rotatably installed on one side of the workbench 1 via a hinge.

[0029] In this embodiment, the burrs of the concave purlin are located at the top. The purlin is placed on the top of the workbench 1, and the drive mechanism 8 drives the conveying mechanism 9 to move, so that the conveying wheel 93 of the conveying mechanism 9 contacts the outer sides of the purlin. This structure is simple and adaptable to purlins of different widths. The conveying mechanism 9 drives the conveying wheel 93 to rotate, and the rotation of the conveying wheel 93 drives the purlin to move, which has the function of automatic feeding. The purlin moves to the bottom of the grinding mechanism, and the grinding mechanism deburrs the top of the purlin. The guide roller 5 reduces the friction between the purlin and the workbench 1, making it easier for the conveying mechanism 9 to drive the purlin to move. The debris generated by deburring falls into the inside of the collection tank 2 due to gravity. After a certain amount of debris is collected, the debris is cleaned by opening the side door 15.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the drive mechanism 8 includes two positive and negative screws 81. The two positive and negative screws 81 are rotatably installed inside the two first mounting slots 3 through bearings. One end of each of the two positive and negative screws 81 passes through the workbench 1 and is connected to a synchronous pulley 82. A synchronous belt 83 is provided between the two synchronous pulleys 82. A first motor 84 is fixedly installed on one side of the workbench 1, and the output end of the first motor 84 is connected to one of the positive and negative screws 81. The first motor 84 drives one of the positive and negative screws 81 to rotate. Due to the cooperation of the synchronous pulley 82 and the synchronous belt 83, the two positive and negative screws 81 rotate together, thereby synchronously changing the position of the four conveying mechanisms 9, so that the conveying wheels 93 of the four conveying mechanisms 9 convey the purlin in the center.

[0031] In one embodiment, such as Figure 1 and Figure 3As shown, the conveying mechanism 9 includes a movable frame 91, which is threaded to the outside of the positive and negative screws 81. Two third mounting slots 92 are formed on one side of the movable frame 91. Conveying wheels 93 are rotatably mounted inside each of the two third mounting slots 92 via bearings. The top of one of the conveying wheels 93 passes through the movable frame 91 and is keyed to a first gear 94. A second motor 95 is fixedly mounted on the top of the movable frame 91. A second gear 96 is keyed to the output end of the second motor 95, and the second gear 96 meshes with the first gear 94. When all four conveying wheels 93 are in contact with the outside of the purlin, the second motor 95 drives the second gear 96 to rotate, which in turn drives the first gear 94 to rotate, which in turn drives the conveying wheels 93 to rotate, thus conveying the purlin. This greatly improves the efficiency of purlin deburring. Furthermore, each conveying mechanism 9 has two conveying wheels 93, significantly improving the stability of purlin conveying and ensuring that there is no deviation during the purlin conveying and grinding process, thus improving practicality.

[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, the grinding mechanism includes a lifting frame 10. The top of the lifting frame 10 is fixedly installed to the output end of the hydraulic cylinder 7. Two rollers 11 are rotatably installed inside the lifting frame 10 via bearings. A grinding belt 12 is provided between the two rollers 11. A third motor 13 is fixedly installed on one side of the lifting frame 10, and the output end of the third motor 13 is connected to one of the rollers 11. The hydraulic cylinder 7 drives the lifting frame 10 to move downward, so that the grinding belt 12 contacts the burrs on the top of the purlin. The third motor 13 drives the rollers 11 to rotate, thereby causing the grinding belt 12 to rotate, effectively deburring the purlin.

[0033] In one embodiment, such as Figure 4 and Figure 5 As shown, a cleaning mechanism 14 is provided on the outside of the lifting frame 10. The cleaning mechanism 14 includes two mounting sleeves 141, which are respectively located on the outer sides of the lifting frame 10. A sliding rod 142 is slidably installed inside each of the two mounting sleeves 141. A brush 143 is provided at one end of each of the two sliding rods 142. A knob 144 is threadedly connected to one side of each of the two mounting sleeves 141. After long-term use, a large amount of debris will adhere to the surface of the polishing belt 12. Loosening the knob 144 allows the sliding rod 142 to slide inside the mounting sleeve 141, thereby changing the position of the brush 143 so that the brush 143 contacts the polishing belt 12. After adjustment, the knob 144 is locked. At this time, the polishing belt 12 rotates, and the brush 143 can remove the debris from the surface of the polishing belt 12, improving the deburring effect.

[0034] The above embodiment discloses a deburring device for purlin production. The burrs of the concave purlin are located at the top. The purlin is placed on the top of the workbench 1. The first motor 84 drives one of the positive and negative screws 81 to rotate. Due to the cooperation of the synchronous pulley 82 and the synchronous belt 83, the two positive and negative screws 81 rotate together, thereby synchronously changing the position of the four conveying mechanisms 9. This allows the conveying wheels 93 of the four conveying mechanisms 9 to centrally convey the purlin. The second motor 95 drives the second gear 96 to rotate. The second gear 96 drives the first gear 94 to rotate. The first gear 94 drives the conveying wheel 93 to rotate, thereby conveying the purlin.

[0035] The hydraulic cylinder 7 drives the lifting frame 10 to move downward, so that the grinding belt 12 contacts the burrs on the top of the purlin. The third motor 13 drives the roller 11 to rotate, which in turn causes the grinding belt 12 to rotate, effectively deburring the purlin. The debris generated during deburring falls into the collection tank 2 due to gravity. After a certain amount of debris is collected, the debris is cleaned by opening the side door 15.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
