Description

Technical Field

[0001] This utility model relates to the field of veneer laminating technology, and specifically to a veneer laminating machine for processing sheet metal. Background Technology

[0002] A veneer lathe is used to process wood segments of a certain length and diameter into single-piece sheets for the production of plywood, veneer boards, and other engineered wood products. The main technical parameters of a veneer lathe are the maximum length and diameter of the wood segments it can process. The veneer lathe is one of the main pieces of equipment for plywood production. Veneer lathes are divided into cassette lathes and cassette lathes. Cassette lathes are suitable for large-diameter wood, while cassette lathes are used for small-diameter wood.

[0003] However, traditional veneer laminating machines lack thickness detection and are commonly found in older or basic models, relying solely on mechanical limits or manual sampling to control thickness. Thickness fluctuations cannot be monitored in real time due to factors such as blade wear and changes in wood moisture content, and sorting relies on manual experience, resulting in a high misjudgment rate. Furthermore, they lack data-driven quality traceability and cannot meet production demands. Therefore, this paper proposes a veneer laminating machine for board processing to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a veneer laminating machine for sheet metal processing, which aims to solve the problem that traditional veneer laminating machines lack thickness detection and rely solely on manual experience, resulting in a high misjudgment rate.

[0005] To solve the above-mentioned technical problems, this utility model provides a veneer laminating machine for sheet metal processing, including a veneer laminating machine body and a conveying device fixed to one side of the veneer laminating machine body. The veneer laminating machine body has a feeding port adapted to the conveying device, and the conveying device is equipped with a detection mechanism. The testing mechanism consists of a gantry frame, a testing component, and an adjustment component; The detection assembly includes a concave frame, with rollers mounted on the inner bearing of the concave frame, a sleeve and a telescopic rod provided on the top side of the concave frame, the telescopic rod being telescopically connected to the sleeve, and a return spring and a contact rod fixed at the top of the telescopic rod, and a pressure sensor fixed on the inner top wall of the sleeve. The adjustment assembly includes an electric telescopic rod, a slide block, and a linkage frame.

[0006] The present invention is further configured such that the gantry frame is fixed to the top side of the conveying equipment by bolts, and the detection component is located above the conveying equipment.

[0007] The present invention is further configured such that the sleeve is hollow inside, the top end of the telescopic rod extends into the sleeve, and the top side of the return spring is fixed to the top wall of the sleeve.

[0008] The present invention is further configured such that a gap is left between the contact rod and the pressure sensor, and the sleeve is detachably installed on the bottom side of the slide by bolts.

[0009] The present invention is further configured such that the slide block is composed of a connecting seat and a sliding sleeve, the connecting seat and the sliding sleeve are welded together, and the sleeve is fixed to the bottom side of the sliding sleeve by bolts.

[0010] The present invention is further configured such that there are multiple detection components and multiple slides, the multiple detection components and multiple slides are distributed laterally at equal intervals, and the connecting seat in the rightmost slide is fixed with a connecting block to the output end bracket of the electric telescopic rod.

[0011] The present invention is further configured such that all of the plurality of sliding blocks are hinged to the linkage frame, and the linkage frame is composed of a first connecting arm and a second connecting arm.

[0012] The present invention is further configured such that the number of the first connecting arms is four, the number of the second connecting arms is several, the four first connecting arms are arranged symmetrically in pairs, the several second connecting arms are arranged crosswise and hinged to the two pairs of first connecting arms, and a guide rail for guiding multiple slides is fixed on the outer wall of the gantry.

[0013] Compared with the prior art, this utility model provides a veneer laminating machine for sheet metal processing: 1. This veneer cutting machine for sheet metal processing can provide real-time feedback on the thickness changes of the sheet metal through the contact between the rollers and the sheet metal.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar parts.

[0018] Please see Figures 1 to 5 This embodiment describes a veneer laminating machine for processing sheet metal, comprising a laminating machine body 1 and a conveying device 2 fixed to one side of the laminating machine body 1. The laminating machine body 1 has a discharge port 11 adapted to the conveying device 2. The conveying device 2 is equipped with a detection mechanism 3. A material gripping structure (not shown in the figure) is located near the discharge end of the conveying device 2, which, in conjunction with the detection mechanism 3, removes defective sheet metal from the conveying device 2. The laminating machine body 1 is a conventional technology known to the public in the prior art; therefore, its specific structural composition and working principle will not be described in detail here. The conveying device 2 is equipped with a PLC control device.

[0019] The inspection mechanism 3 consists of a gantry frame 301, an inspection component 302, and an adjustment component. The inspection component 302 includes a concave frame 3021, with rollers 3022 mounted on the inner bearings of the concave frame 3021. The rollers 3022, mounted on the inner bearings of the concave frame 3021, allow free rotation and rolling contact with the surface of the sheet material, significantly reducing friction. This design effectively protects the surface of the sheet material, preventing scratches or damage caused by friction and ensuring the processing quality of the sheet material. A sleeve 3023 and a telescopic rod 3024 are provided on the top side of the concave frame 3021. The telescopic rod 3024 is telescopically connected to the sleeve 3023, and a return spring 3025 and a contact rod 3026 are fixed to the top of the telescopic rod 3024. A pressure sensor 3027 is fixed on the inner top wall of the sleeve 3023. Specifically, the gantry frame 301 is bolted to the top side of the conveying equipment 2, and the inspection component 302 is located above the conveying equipment 2. The sleeve 3023 is hollow inside, the top of the telescopic rod 3024 extends into the sleeve 3023, and the top side of the return spring 3025 is fixed to the inner top wall of the sleeve 3023.

[0020] It should be noted that a gap exists between the contact rod 3026 and the pressure sensor 3027, and the sleeve 3023 is detachably mounted to the bottom side of the slide block 304 via bolts. The contact between the roller 3022 and the plate material provides real-time feedback on the thickness changes of the plate material. When the plate material thickness is uneven, the roller 3022 will drive the concave frame 3021 and the telescopic rod 3024 to extend and retract within the sleeve 3023. The contact status between the contact rod 3026 and the pressure sensor 3027 then converts the thickness information into a pressure signal for output. This real-time feedback mechanism ensures accurate detection of the plate material thickness. The slide block 304 consists of a connecting seat 3041 and a sliding sleeve 3042, which are welded together. The sleeve 3023 is fixed to the bottom side of the sliding sleeve 3042 via bolts.

[0021] Furthermore, the telescopic connection between the sleeve 3023 and the telescopic rod 3024, along with the return spring 3025, provides excellent buffering capacity for the detection assembly 302. When the plate thickness changes, the telescopic rod 3024 can extend and retract within the sleeve 3023 to adapt to the thickness change, while the return spring 3025 ensures that the gap between the contact rod 3026 and the pressure sensor 3027 remains stable. This design effectively avoids detection errors caused by sudden changes in plate thickness, ensuring the stability of the detection.

[0022] To accommodate the inspection of plates of different sizes, the adjustment assembly includes an electric telescopic rod 303, a slide block 304, and a linkage frame 305. Multiple inspection components 302 and multiple slide blocks 304 are distributed laterally at equal intervals. The connecting seat 3041 in the rightmost slide block 304 is fixed to the output end bracket of the electric telescopic rod 303 with a connecting block 307. All slide blocks 304 are hinged to the linkage frame 305. It should be noted that the linkage frame 305 consists of first connecting arms 3051 and second connecting arms 3052. There are four first connecting arms 3051 and several second connecting arms 3052. The four first connecting arms 3051 are arranged symmetrically in pairs, and the several second connecting arms 3052 are arranged crosswise and hinged to the two pairs of first connecting arms 3051. Guide rails 306 are fixed on the outer wall of the gantry frame 301 to guide the multiple slide blocks 304. The middle slide 304 on the multiple slides 304 is fixed to the outer wall of the guide rail 306, and the remaining left and right slides 304 are slidably connected to the guide rail 306. The left and right sets of first connecting arms 3051 are hinged at opposite ends, and the left and right sets of first connecting arms 3051 are respectively hinged at the ends of the leftmost and rightmost second connecting arms 3052 among a number of second connecting arms 3052. When the electric telescopic rod 303 extends and retracts, driving the rightmost slide 304 to a certain position, the deformation of the linkage frame 305 enables the multiple detection components 302 to adjust their spacing synchronously.

[0023] The working principle of the above embodiments is as follows: When the conveyor 2 is started, the board enters the inspection area. The electric telescopic rod 303 adjusts the spacing of the inspection components 302 according to the preset board width through the linkage frame 305. When the board moves from the conveyor 2 to the veneer body 1, the rollers 3022 of the inspection components 302 contact the surface of the board. The rollers 3022 float up and down with the change of the board thickness, which drives the concave frame 3021 and the telescopic rod 3024 to extend and retract within the sleeve 3023. The return spring 3025 at the top of the telescopic rod 3024 provides cushioning. The gap between the contact rod 3026 and the pressure sensor 3027 varies with the thickness of the plate. When the plate thickness is uneven, the contact rod 3026 contacts the pressure sensor 3027 to generate a pressure signal and provide real-time feedback of the plate thickness data.

[0024] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0025] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
