Description

TECHNICAL FIELD

[0001] The utility model relates to door and window processing equipment technical field, concretely relates to synchronous material lifting device for sawing and milling workstation feeding. BACKGROUND

[0002] Sawing and milling workstation is door and window intelligent processing equipment, and mainly completes the milling and sawing of door and window profiles. At present, the working principle and overall structure layout of sawing and milling workstation are relatively mature, mainly including automatic feeding unit, four-head milling unit, sawing unit and automatic unloading unit, for example, a multifunctional profile automatic sawing and milling processing system and method (application publication number: CN117600836A) disclosed by Chinese patent.

[0003] With the popularization and application of sawing and milling workstation, especially after the user's personal experience, some new technical problems are fed back successively, for example, when the profile is fed, the mechanical hand cannot accurately clamp the profile, the main reason is that the existing lifting mechanism usually adopts two cylinder driving lifting, and the synchronization of the two cylinders is poor, and the clamping action of the mechanical hand is rapid, so that the profile is clamped in the inclined state, and the profile cannot be accurately clamped, which affects the milling and sawing process precision, and even causes the problem that the profile cannot be clamped. Therefore, it is necessary to optimize and improve the existing lifting mechanism, so as to realize synchronous lifting of the profile and ensure that the profile can be accurately clamped and fed.

[0004] It should be noted that the above content belongs to the technical cognition of the inventor and does not necessarily constitute the prior art. INVENTION CONTENTS

[0005] The utility model aims at solving the problems existing in the prior art, and provides a synchronous material lifting device for sawing and milling workstation feeding, which has the advantages of reasonable structure design, good profile lifting synchronization and the like.

[0006] The utility model realizes the above-mentioned purposes by adopting the following technical solutions:

[0007] The synchronous material lifting device for sawing and milling workstation feeding comprises a feeding rack, a plurality of bases are horizontally and interval arranged on the feeding rack, guide rails are horizontally arranged on the bases, sliding seats are arranged on the guide rails, driving rod pieces are rotatably arranged on the sliding seats, adjacent two sliding seats are connected through pull rods, at least one driving cylinder is horizontally arranged on the base, the driving cylinder is connected with the sliding seat, a plurality of lifting sliding blocks are horizontally and interval arranged on the feeding rack, lifting guide rails are vertically arranged on the lifting sliding blocks, lifting sliding seats are arranged on the lifting guide rails, the driving rod pieces are rotatably connected with the lifting sliding seats, lifting cross beams are arranged on the upper ends of the lifting sliding seats, and a plurality of material supporting rods are interval arranged on the lifting cross beams along the length direction of the lifting cross beams.

[0008] The drive rod includes a double-threaded rod, with fisheye connectors at both ends. One fisheye connector is mounted on the slide block by a screw, and the other fisheye connector is mounted on the lifting slide block by a screw.

[0009] The feeding frame is provided with two bases spaced horizontally, and a connecting seat is provided between the two bases. The two ends of the connecting seat are connected to the bases by pull rods. The feeding frame is provided with three sets of lifting sliders spaced horizontally. Each set of lifting sliders includes two lifting sliders spaced vertically. The connecting seat is connected to the middle lifting slider by a drive rod.

[0010] A drive cylinder is provided on each of the two ends of the base. The drive cylinder is mounted on the base through a cylinder seat and is connected to the slide through a cylinder connector.

[0011] The lifting beam is provided with multiple rollers spaced laterally.

[0012] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0013] By designing guide rails, slide blocks, and tie rods, all slide blocks are connected in series and move laterally synchronously. Then, the slide blocks and lifting slide blocks are linked together by drive rods. Since all slide blocks move synchronously, all lifting slide blocks also rise and fall synchronously, thus ensuring that the lifting beam is lifted synchronously. Attached image description:

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0021] Furthermore, the terms “horizontal,” “vertical,” “longitudinal,” etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "provided with," "set up," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1-2 As shown, a synchronous lifting device for loading materials in a sawing and milling workstation includes a loading frame 1 (an existing component in the loading unit of an existing sawing and milling workstation). Multiple bases 2 are horizontally spaced on the loading frame 1. Guide rails 3 are horizontally spaced on the bases 2. Slides 4 are mounted on the guide rails 3. Driving rods 5 are rotatably mounted on the slides 4. Adjacent slides 4 are connected by pull rods 6. At least one base 2 is horizontally spaced with a driving cylinder 7, which is connected to the slide 4. Multiple sets of lifting sliders 8 are horizontally spaced on the loading frame 1. Lifting guide rails 9 are vertically spaced on the lifting sliders 8. Lifting slides 10 are mounted on the lifting guide rails 9. The driving rods 5 are rotatably connected to the lifting slides 10 (initially, the driving rods 5 are inclined to facilitate lifting the lifting slides 10). A lifting beam 11 is located at the upper end of the lifting slides 10. Multiple material-supporting rollers 12 are spaced along the length of the lifting beam 11. By designing guide rail 3, slide block 4 and tie rod 6, all slide blocks 4 are connected in series and move laterally synchronously. Then, the slide blocks 4 and lifting slide blocks 10 are linked together by drive rod 5. Since all slide blocks 4 move synchronously, all lifting slide blocks 10 also lift synchronously, thereby ensuring that the lifting beam 11 is lifted synchronously.

[0024] The drive rod 5 includes a double-threaded rod 501 (with opposite thread directions at both ends, i.e., a forward and reverse thread structure). Each end of the double-threaded rod 501 is equipped with a fisheye connector 502 (also called a spherical bearing). One fisheye connector 502 is mounted on the slide block 4 via a shear screw 503, and the other fisheye connector 502 is mounted on the lifting slide block 10 via a shear screw 503. This structure not only allows for adjustable spacing but also facilitates connection, meeting the requirements for flexible rotation and power transmission.

[0025] The loading frame 1 has two bases 2 spaced horizontally, and a connecting seat 13 is provided between the two bases 2. The two ends of the connecting seat 13 are connected to the bases 2 by tie rods 6 respectively. The loading frame 1 has three sets of lifting sliders 8 spaced horizontally, and each set of lifting sliders 8 includes two vertically spaced lifting sliders 8. The connecting seat 13 is connected to the lifting slide 10 located in the middle by a drive rod 5. In practical applications, since the lifting beam is relatively long (usually greater than 6 meters), setting the drive rod 5, lifting sliders 8, lifting guide rails 9 and lifting slide 10 in the middle helps to provide structural stability, making the lifting smoother and more durable.

[0026] Drive cylinders 7 are respectively installed on the bases 2 at both ends. The drive cylinders 7 are mounted on the bases 2 via cylinder seats 14 and connected to the slide 4 via cylinder connectors 15. Two drive cylinders 7 are used for driving, typically one pulls and the other pushes, to ensure more stable and reliable driving.

[0027] The lifting beam 11 is provided with multiple rollers 16 spaced laterally. The rollers 16 are used to position the profile 17.

[0028] The working process of the synchronous lifting device for loading the sawing and milling workstation in this application is as follows:

[0029] like Figure 3 As shown, the conveyor belt 18 (existing technology) transports the profile 17 longitudinally. When it reaches the roller 16, the drive cylinder 7 is activated, which drives all the slides 4 to move laterally synchronously via the pull rod 6. While the slides 4 are moving laterally, the drive rod 5 drives all the lifting slides 10 to lift upwards synchronously, thereby driving the lifting beam 11 to lift synchronously. The material support roller 12 on the lifting beam 11 lifts the profile 17 on the conveyor belt 18 synchronously and removes it from the conveyor belt 18. Then, the material loading robot (existing technology, not shown in the figure) clamps the profile 17 for loading.

[0030] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0031] Any aspects of this utility model not described in detail are known to those skilled in the art.
