[0043] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the following will combine the technical scheme in the utility model embodiment to make clear and complete description, obviously, the described embodiment is the part embodiment of the utility model, rather than all embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without paying creative labor belong to the protection scope of the utility model.

[0044] The preferable embodiment of the utility model is a kind of conveying device and processing device;As shown in Figure 1 The processing device can be used for laser cutting equipment to carry out laser cutting, laser engraving equipment to carry out laser engraving, laser marking equipment to carry out laser marking and knife cutting processing equipment to carry out knife cutting, etc., and the processed goods are conveyed after the processed goods are conveyed by conveying device 1 and processed. 1 is conveyed, then the processing head is set on conveying device 1, when the processed goods are conveyed to conveying device 1 by the processing head and then conveyed to the next process by conveying device 1, all should belong to the protection scope of the utility model patent, and the laser engraving equipment is taken as an example to be explained in the application.

[0045] Specifically, as Figures 2-5As shown, the conveying device 1 comprises a conveying platform 101, on which a feeding lug 109 can be arranged and fixedly connected with the laser equipment, and the conveying platform 101 is connected with side end covers 104 on the left and right sides, and the side end covers 104 are connected with a lifting assembly above, which comprises a lifting fixed plate 108 arranged on the upper end of the side end cover 104, and the lifting fixed plate 108 is movably connected with a lifting plate 116 below, and the lifting plate 116 is provided with a plurality of sets of compression wheel groups 118 at the lower end, and the lifting plate 116 is fixedly provided with a lifting device 115, and the lifting device 115 is rotated to lift the lifting plate 116 to drive the compression wheel groups 118 to lift, and the conveying platform 101 is provided with conveying rollers 107 corresponding to the compression wheel groups, and a gap for conveying the processed materials is left between the compression wheel groups 118 and the conveying rollers 107, and the size of the gap changes with the up-and-down movement of the compression wheel groups 118, so as to realize the clamping and conveying of the processed materials of different thicknesses. In order to keep the processed materials entering the conveying platform 101 flat, an upper pressing shaft 103 is arranged on one side of the conveying platform 101, and a supporting shaft 106 is arranged below the upper pressing shaft 103, and the supporting shaft 106 and the upper pressing shaft 103 are both fixed through the side end cover 104, and a gap is also left between the supporting shaft 106 and the upper pressing shaft 103, which can be adjusted according to the needs to ensure that the processed materials entering the conveying platform 101 remain flat, facilitating the subsequent conveying and processing of the processed materials.

[0046] Further, as shown in Figure 5 and Figure 8 In order to automatically convey the processed materials, a plurality of sets of conveying rollers 107 are connected through a conveying shaft 110, the conveying shaft 110 synchronously rotates the plurality of sets of conveying rollers, a conveying knob 114 is arranged on one side of the conveying roller 107, and a synchronous belt pulley 113 is sleeved on the conveying shaft 110, and a motor 111 and a synchronous belt 112 are arranged in the conveying platform 101 corresponding to the synchronous belt pulley 113, the synchronous belt connects the synchronous belt pulley 113 and the motor 111 to realize the rotation of the synchronous belt pulley driven by the motor. After the processed materials are compressed, the conveying knob 114 can be manually rotated to drive the conveying roller 107 on the conveying shaft 110 to rotate, and the conveying roller 107 is provided with a mesh pattern knurl, which drives the processed materials to move forward by the friction between the mesh pattern knurl and the surface of the processed materials. In order to ensure that the processed materials can be conveyed smoothly, the compression wheel groups 118 can be adjusted to move downward to change the pressure between the compression wheel groups 118 and the conveying rollers 107, so that the friction is large enough but will not damage the processed materials. After the processed materials are conveyed to the appropriate position, the motor 111 is operated to drive the synchronous belt 112 to rotate and in turn drive the synchronous belt pulley 113 to rotate, and the rotation of the synchronous belt pulley 113 drives the conveying shaft 110 to rotate to realize the rotation of the conveying roller 107, so as to automatically convey the processed materials to the laser equipment for processing, thereby improving the stability of the processed materials in the conveying and processing process.

[0047] Further, as shown in Figures 5-6 the lifting device 115 includes a lead screw 1156 connecting the lifting fixed plate 108 and the lifting plate 116, the upper end of the lead screw is provided with a lifting knob 1151, and the synchronous rotation of the lead screw is realized by connecting the lifting knob and the lead screw to rotate the lifting knob, and the lower end of the lead screw is connected with the lifting plate through a lead screw cover 122. In order to make the lead screw rotate to make the lifting fixed plate not move up and down and the lifting plate move up and down, the lifting device further includes a bearing 1152, the bearing is sleeved outside the lead screw and the lifting fixed plate is connected with the lead screw through the bearing, and the bearing is sleeved with a lifting lead screw seat 1153, the bearing 1152 and the lead screw seat 1153 limit the lead screw 1156, so that the lead screw can only rotate relative to the lifting fixed plate 108, and the lead screw 1156 is fixed with a lead screw nut 1155, which makes the lead screw rotate to drive the lifting plate 116 to rise and fall, and the lead screw 1156 is connected with a belt pulley 1154, which makes the two groups of lifting devices rotate synchronously to make the lifting plate rise and fall at the same time, avoiding the error caused by single side lifting of the lifting device 116, and at the same time, since the lifting plate 116 rises and falls on both sides at the same time, the multiple compression wheel sets 118 rise and fall at the same time, so that the distance between each compression wheel set 118 and the conveying roller 107 is the same, and the compression effect of each compression wheel set 118 is the same. It should be noted that the lifting knob can be arranged on only one group of lifting devices, since the lifting knob is arranged above the lifting fixed plate, it is also convenient to operate the lifting knob, and adjustment can be realized without walking, which is more convenient. When the conveying device is large, it is also more convenient to rotate the lifting knob. The lifting device can also be arranged in three or more groups, when the processing device is large, the length of the lifting fixed plate and the lifting plate is long, at this time, multiple lifting devices are relatively evenly distributed on the lifting fixed plate and the lifting plate and keep synchronous and same direction rotation, so that the lifting plate always keeps parallel up and down movement. At the same time, when the conveying device is small, only one group of lifting devices can be arranged, and the lifting device is arranged at the relatively middle position of the conveying device, which can also drive the lifting plate to keep parallel up and down movement. The lifting knob can also be driven by a motor to rotate multiple knobs synchronously in the same direction to make the lifting device rotate synchronously in the same direction, so as to realize the mode of motor driving or manual driving to make the lifting device rotate.

[0048] Further, as shown in Figure 7As shown, the compression wheel set 118 includes a compression plate 1181, and a double-pass stud 1182 arranged below the compression plate 1181, the lower end of the double-pass stud 1182 is connected with a roller seat 1185, a roller 1186 is installed on the roller seat 1185 and fixed by a screw, so as to realize the rotation of the roller 1186 in the roller seat 1185. The double-pass stud 1182 is externally sleeved with a spring 1184, and the spring 1184 is arranged between the lifting plate 116 and the roller seat 1185. When the lifting plate 116 is lowered to compress the material to be processed, the entire compression wheel set 118 will be upwardly moved due to the reaction force, and at the same time, the spring 1184 will be compressed. When the lifting plate 116 is raised, the spring 1184 will be reset and rebound, and at the same time, the compression wheel set 118 will be reset.

[0049] Further, as shown in Figure 1 In order to make the processing device cope with longer or infinite length of the material to be processed, the support frame 2 is arranged on both sides of the conveying device 1, and two groups of support frames are arranged on each side, which facilitates the conveying of the material. At the same time, the support frame can be connected with the conveying device in the form of plug-in, which facilitates the disassembly and installation of the support frame, and reduces the transportation volume after disassembly.

[0050] Further, as shown in Figures 9-11As shown, the support frame 2 comprises a large support frame 204 and a small support frame 205, and the large support frame and the small support frame are quickly disassembled in the way of insertion fitting. In order to realize the insertion fitting of the large support frame and the small support frame, the large support frame and the small support frame are inconsistent in size, and the small support frame 205 is partially inserted into the large support frame 204, and the large support frame and the small support frame are connected together through the V-shaped elastic piece 206. The large support frame and the small support frame are both provided with a hollow, the V-shaped elastic piece is arranged in the hollow, and the V-shaped elastic piece 206 is provided with a ball. The large support frame and the small support frame are both provided with a circular hole corresponding to the ball. When the large support frame and the small support frame need to be assembled, the V-shaped elastic piece 206 is embedded into the circular hole of the small support frame 205 by pressing the V-shaped elastic piece 206, and then the small support frame 205 is inserted into the large support frame 204. When the ball on the V-shaped elastic piece reaches the fixed position of the circular hole during the insertion process, the ball is clamped into the circular hole, so that the large support frame and the small support frame are connected together through the V-shaped elastic piece, and the relative movement of the large support frame and the small support frame is limited. When disassembly is needed, the ball is only needed to enter the circular hole by pressing the V-shaped elastic piece 206, so that the two support frames can be pulled out. In order to avoid the relative shaking of the large support frame 204 and the small support frame 205 caused by the gap between the ball on the V-shaped elastic piece and the circular hole during the insertion process, a rubber pad 207 is arranged at the ball. The rubber pad is the same height as the small support frame, so that the V-shaped elastic piece moves along the length direction of the support frame in the support frame. At the same time, the rubber pad can also avoid shaking when more support frames are inserted subsequently. The ball of the V-shaped elastic piece 206 is matched with the rubber pad 207, the V-shaped elastic piece 206 and the rubber pad 207 are tightly matched with each other, the small support frame 205 and the V-shaped elastic piece 206 are assembled together through the rubber pad 207, and the shaking of the V-shaped elastic piece 206 in the support frame is avoided, so that the shaking when more support frames are inserted subsequently is avoided, and the insertion fitting mode also ensures that the large support frame and the small support frame remain parallel. It should be noted that a limiting block can also be arranged in the large support frame or the small support frame, so that the V-shaped elastic piece is more accurately clamped into the circular hole, and the connection and disassembly of the large support frame and the small support frame are more convenient. It should be noted that the V-shaped spring in the present application is arranged in the small support frame, and it can also be arranged in the large support frame according to needs, which also belongs to the protection range of the present application. At the same time, the V-shaped spring and the large support frame or the small support frame are embedded and clamped in the way, the ball on the V-shaped spring can be replaced by other shaped clamping balls, and the circular hole on the corresponding large support frame or small support frame can be replaced by the corresponding clamping hole. The large support frame and the small support frame are connected through the clamping of the clamping ball and the clamping hole, which all belong to the protection range of the present application.

[0051] Further, as Figure 2 , Figures 9-10 and Figures 12-13As shown, the support frame 2 is connected with the conveying device 1 through the connecting block 201. The conveying device is provided with connecting plates 102 on the front and back sides, and the connecting plates are provided with insertion slots 105. The connecting block 201 is provided with an I-shaped block 2013 which is inserted into the insertion slot and is fixed with the conveying device through a locking block 2010. Due to the insertion slot, the distance between the two groups of support frames can be adjusted according to the size of the processed material, and then the locking block is connected and fixed with the conveying device through screws, so that the support frame is prevented from moving in the sliding groove when the processed material is transported. The other end of the connecting block is provided with a plurality of buckling positions, including upper and lower buckling positions 2011 and left and right buckling positions 2012. The large support frame is provided with buckling hole 2040 corresponding to the upper and lower buckling positions, so that the connecting block and the large support frame are buckled and connected in the upward and downward directions. The small support frame is provided with buckling holes corresponding to the left and right buckling positions 2012, so that the connecting block and the small support frame are buckled and connected in the left and right directions. This facilitates the buckling connection and disassembly of the connecting block with the large support frame and the small support frame, and allows the large support frame and the small support frame to be connected with the connecting block during installation, which is simple and convenient, and does not affect the use of the subsequent support frame.

[0052] Further, as shown in Figures 9-10 and Figures 14-16 , the large support frame 204 and the small support frame 205 are provided with small platforms above. The small platforms are connected with pulley blocks 203. The pulley blocks include pulley plates 2031 and sliding grooves 2032 provided on both sides of the pulley plates 2031. The pulley blocks are connected with the large support frame 204 and the small support frame 205 through the sliding grooves 2032, so as to realize the sliding of the pulley blocks in the small platforms and make the heights of the pulley blocks consistent after installation, thereby ensuring the stability of the processed material when it is conveyed to the processing equipment. The pulley blocks 2030 are provided on the pulley seats 2031 to reduce the resistance when the support frame is conveyed. The large support frame 204 and the small support frame 205 are provided with stop blocks 202 on both sides. The stop blocks are fixed with the support frame by screws. When a plurality of pulley blocks are provided on the support frame, the stop blocks can be used to limit the left and right movement of the pulley blocks, so that the pulley blocks 203, the large support frame 204 and the small support frame 205 are limited and fixed as a whole.

[0053] Further, as shown in Figures 9-10 and Figure 17 , the connecting block 201 is connected with supporting legs 208 at the lower end. The supporting legs are inserted into the connecting members through round holes or screw holes to provide support force for the support frame. The round hole connection can facilitate the installation and removal of the supporting legs, and can avoid the bending of the support frame when processing longer materials. Round holes can also be provided below the large support frame 204 and the small support frame 205 to directly connect the supporting legs 208 with the large support frame and the small support frame, so that the supporting legs directly provide support force for the support frame, thereby further avoiding the bending of the support frame and making the material conveying more stable.
