Description

Technical Field

[0001] This utility model relates to a feeding mechanism, specifically a non-contact layer feeding mechanism, belonging to the technical field of oven auxiliary equipment. Background Technology

[0002] In the industrial production process of printed sheets, the sheets after ink printing need to enter a three-dimensional baking oven to cure the ink through baking at a specific temperature and time to ensure the adhesion and stability of the printed pattern. This step is a key step to ensure the performance of printed sheet products. After the curing process is completed, a special unloading mechanism is needed to take the sheet out of the cavity of the three-dimensional baking oven and transfer it to the subsequent cutting, stacking or packaging process.

[0003] However, when current 3D oven unloading mechanisms are adapted to printed sheets, suction cup adsorption mechanisms require the suction cup to be directly attached to the printed surface for adsorption, which easily leaves adsorption marks. Improper negative pressure control can also cause ink to fall off. The gripper of the robotic arm clamping mechanism can scratch the pattern by rubbing against the printed surface, which is more damaging to high-precision halftone printing or thin sheets, resulting in a high product defect rate and failing to meet the requirements of high-quality printed sheet production. Therefore, a non-contact layer unloading mechanism is needed to ensure product quality and achieve efficient unloading. Utility Model Content

[0004] The purpose of this invention is to provide a non-contact sheet feeding mechanism to solve the above problems. By using an inserter that only contacts the non-printing surface of the sheet, the upper printing surface of the sheet is always suspended and non-contact, which completely avoids problems such as scratching, wear, and ink peeling on the printing surface during the transfer process, and effectively ensures the product quality of the printed sheet.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 As shown, a non-contact layer feeding mechanism includes a baking oven body 1, a feeding structure 2 on the baking oven body 1, a sliding block 201 on the feeding structure 2, two sliding blocks 202 slidably connected to the baking oven body 1, a crossbar 203 fixedly connected between the two sliding blocks 202, a plurality of connecting sleeves 204 fixedly connected to the crossbar 203, a handle 205 fixedly connected to the connecting sleeve 204, an inclined surface 207 on the handle 205, and a lifting structure 4 on the baking oven body 1.

[0019] As a technical optimization of this utility model, a first guide rail 206 is fixedly connected to the slide block 201. A first driving member 208 (preferably a hydraulic rod) mounted on the crossbar 203 begins operation. The driving end of the first driving member 208 pushes the slider 202 to slide along the first guide rail 206 on the slide block 201. The first guide rail 206 provides reliable guidance and limiting for the sliding of the slider 202, ensuring that the two sliders 202 drive the crossbar 203 to move smoothly. The multiple connecting sleeves 204 on the crossbar 203 move synchronously accordingly. The insert 205 on the connecting sleeve 204 moves closer to the gap below the sheet. The inclined surface 207 on the insert 205 can play a good guiding role, allowing the insert 205 to be inserted more smoothly into the gap between the sheet and the support surface of the unloading station. The multiple inserts 205 can support the sheet from different positions, ensuring the stability of the sheet when it is lifted. The slider 202 is slidably connected to the first guide rail 206. The first driving component 208 is installed on the crossbar 203. The driving end of the first driving component 208 is installed on the slide block 201.

[0020] As a technical optimization of this utility model, the lifting structure 4 includes a lifting plate 401. Multiple lifting plates 401 are slidably connected to the oven body 1, and multiple lifting columns 402 are fixedly connected to the lifting plates 401. When the third driving component 403 (preferably a hydraulic rod) installed on the oven body 1 is activated, the multiple third driving components 403 drive the multiple lifting plates 401 to slide upwards. The multiple lifting columns 402, which are linearly arrayed on the lifting plates 401, rise synchronously. The lifting columns 402 abut against the non-printing surface of the sheet and lift the sheet... The lifting columns 402, arranged in a linear array, allow for more even stress distribution on the sheet, preventing bending and deformation during the lifting process. Furthermore, the lifting columns 402 only contact the non-printed surface of the sheet, reducing the contact area and avoiding contact with the printed surface throughout the process, effectively mitigating the risk of scratches or wear on the printed surface. Multiple lifting columns 402 are arranged in a linear array on the lifting plate 401. Multiple third driving components 403 are installed on the oven body 1, and the multiple lifting plates 401 are driven by the multiple third driving components 403.

[0021] As a technical optimization of this utility model, the slide block 201 is driven by the transmission structure 3. The transmission structure 3 includes a mounting base 301. Four mounting bases 301 are mounted on the oven body 1. A mounting shaft 302 is rotatably connected to the mounting base 301. A synchronous pulley 303 is fixedly connected to the mounting shaft 302. Every two synchronous pulleys 303 are driven by a synchronous belt 304. The two slide blocks 201 are respectively fixedly connected to two synchronous belts 304. When the second driving member 306 (preferably a motor) is started, the second driving member 306 drives the mounting shaft 302 to rotate, and the synchronous pulleys 303 on the mounting shaft 302 rotate accordingly. The synchronous belt 304 is driven by the movement of the synchronous belt 304. The two slide blocks 201, which are fixedly connected to the synchronous belt 304, slide along the second guide rail 305 on the oven body 1 towards the sheet material. The second guide rail 305 can ensure the straightness and stability of the slide block 201 during movement and avoid the insertion arm 205 from being unable to be accurately aligned due to the offset of the slide block 201. The second guide rail 305 is fixedly connected to the oven body 1, and the slide block 201 is slidably connected to the second guide rail 305. The two mounting seats 301 are equipped with second driving components 306, and the two mounting shafts 302 are driven by the two second driving components 306 respectively.

[0022] In use, the sheet is first pulled out from the baking cavity of the oven body 1 to the preset unloading station. Then, the third drive unit 403 (preferably a hydraulic rod) installed on the oven body 1 is activated. Multiple third drive units 403 drive multiple lifting plates 401 to slide upward. Multiple lifting columns 402 arranged in a linear array on the lifting plates 401 rise synchronously. The lifting columns 402 abut against the non-printed surface of the sheet and lift the sheet. The linear array of lifting columns 402 can make the force on the sheet more even, avoiding bending and deformation of the sheet during the lifting process. At the same time, the contact area with the sheet is reduced by only the lifting columns 402 contacting the non-printed surface of the sheet, and the printed surface of the sheet is not touched throughout the process, effectively avoiding scratches on the printed surface. To mitigate the risk of wear and tear, after the lifting plate 401 drives the lifting column 402 to lift the sheet to a suitable height, the second drive component 306 (preferably a motor) is activated. The second drive component 306 drives the mounting shaft 302 to rotate, and the synchronous wheel 303 on the mounting shaft 302 rotates accordingly, pulling the synchronous belt 304 for transmission. The two slides 201, which are fixedly connected to the synchronous belt 304, slide along the second guide rail 305 on the oven body 1 towards the sheet. The second guide rail 305 ensures the straightness and stability of the slides 201 during movement, preventing the insert 205 from being inaccurately aligned due to the slides 201 shifting. When the slides 201 move to the preset position, the first drive component 208 (preferably a hydraulic rod) installed on the crossbar 203 begins to work. A driving component 208 pushes the slider 202 to slide along the first guide rail 206 on the slide block 201. The first guide rail 206 provides reliable guidance and limiting for the sliding of the slider 202, ensuring that the two sliders 202 drive the crossbar 203 to move smoothly. The multiple connecting sleeves 204 on the crossbar 203 move synchronously, thereby driving the inserts 205 on the connecting sleeves 204 to move closer to the gap below the sheet. The inclined surface 207 on the insert 205 can play a good guiding role, allowing the insert 205 to be inserted more smoothly into the gap between the sheet and the support surface of the unloading station. The multiple inserts 205 can support the sheet from different positions, ensuring the stability of the sheet when it is lifted. Moreover, the inserts 205 do not come into contact with the non-printing surface of the sheet, avoiding contact with the non-printing surface of the sheet. To avoid contact damage to the printed surface of the sheet, after all the inserts 205 are smoothly inserted under the sheet and firmly support it, the lifting and lowering action is performed. The third drive unit 403 drives the lifting plate 401 to slide the lifting column 402 downward and return to the initial position. At this time, the supporting force of the sheet is entirely borne by the inserts 205, which not only makes room for the subsequent transfer of the sheet by the inserts 205, but also prevents friction marks from being left on the non-printed surface of the sheet because the lifting column 402 separates from the sheet during the lowering process. Finally, the action of transferring the sheet by the inserts 205 is performed. The second drive unit 306 drives the slide 201 to move along the second guide rail 305 away from the oven body 1 through the mounting shaft 302, synchronous pulley 303 and synchronous belt 304. During the movement of the slide 201...The inserter 205 moves synchronously, supporting the sheet, until it is delivered to the designated unloading position, completing the entire unloading process. Throughout the transfer, the inserter 205 only contacts the non-printing surface of the sheet, while the printing surface remains suspended and uncontacted. This completely avoids problems such as scratching, abrasion, and ink peeling on the printing surface during transfer, effectively ensuring the product quality of the printed sheet.
