Description

Technical Field

[0001] This utility model relates to the field of sheet coating technology, specifically a buffer conveying mechanism for sheet coating discharge. Background Technology

[0002] During sheet processing, various functional materials are typically coated onto the substrate sheet to achieve specific functions through curing into a film or layer. In this process, the freshly coated sheet requires a buffer period to allow the surface material time to cure. This process usually takes about 40 seconds, but can be longer or shorter. After this resting period, the sheet can be transported normally to the next process.

[0003] Currently, this process is completed through long conveying distances, which not only takes up space but also makes it difficult to adjust the buffer time. If the time required for material curing is short, it results in waste; if the curing time is extended due to material adjustments, it cannot be adjusted based on production needs. Utility Model Content

[0004] The purpose of this invention is to provide a buffer conveying mechanism for sheet coating discharge. Its conveying layout after sheet coating allows the coated material to have sufficient and adjustable curing buffer time, thereby improving film quality.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A buffer conveying mechanism for sheet coating discharge includes two parallel support frames. A positioning roller, a guide roller, an adjusting roller, and a flipping roller are sequentially installed between the two support frames based on the sheet's winding sequence. The positioning roller is installed on the top of the support frame, and the guide roller is installed on the bottom of the support frame and is vertically corresponding to the positioning roller. The adjusting roller is lower than the flipping roller, and the flipping roller is positioned between the adjusting roller and the guide roller. The horizontal distance between the adjusting roller and the flipping roller is adjustable.

[0007] The support frame includes an upright frame and a base frame connected in an L-shape. The positioning roller is installed at the top of the upright frame, the guide roller is installed at the bottom of the upright frame, and an intermediate roller is also installed in the middle of the upright frame.

[0008] The support frame includes an upright frame and a base frame connected in an L-shape. The positioning roller is installed at the top of the upright frame, and a receiving roller is also installed at the top of the upright frame. The guide roller is installed at the bottom of the upright frame. The receiving roller is installed on the side of the material receiving direction relative to the positioning roller. The lower circumferential surface of the receiving roller is used to bypass the sheet material, and the lower circumferential surface of the receiving roller is lower than the upper circumferential surface of the positioning roller.

[0009] The adjusting roller and the turning roller have opposite displacements in the horizontal direction.

[0010] The support frame includes an upright frame and a base frame connected in an L-shape. A vertically extending mounting plate is fixed on the base frame. A first sliding groove and a second sliding groove are fixed on the mounting plate and are arranged in the same direction and parallel to each other. The first sliding groove and the second sliding groove are both horizontally extended. The first sliding groove is positioned above the second sliding groove in terms of height. The first sliding groove and the second sliding groove are staggered. A first slider is provided in the first sliding groove and is slidably connected thereto. The two ends of the turning roller are rotatably connected to the first slider on the same side. A second slider is provided in the second sliding groove and is rotatably connected to the second slider on the same side. A first fixing member is fixed on the first slider and a second fixing member is fixed on the second slider. Two pulleys are also installed at the same height on the mounting plate. A loop-shaped transmission belt is wound between the pulleys. The first fixing member and the second fixing member are fixed to the top and bottom surfaces of the transmission belt, respectively.

[0011] Above the adjusting roller, there is a lifting roller that can be raised and lowered. At both ends of the roller, there are lifting grooves. Lifting sliders are slidably fitted in the lifting grooves. Both ends of the roller are rotatably connected to the lifting sliders on the same side. A lead screw is installed through the lifting slider. A motor-driven lead screw is vertically and rotatably installed in the lifting groove. The lead screw cooperates with the lead screw.

[0012] The support frame is enclosed by a barrier.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This device is used to guide the freshly coated sheet after coating is completed. By utilizing the downward folding space, it provides ample buffer curing time for the coated surface of the sheet. Furthermore, the adjustable gap between the adjusting roller and the flipping roller allows for the extension of the buffer time, giving the sheet sufficient curing time and ensuring the coating quality.

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0020] Example:

[0021] The main structure of this example includes a support frame, which consists of two symmetrically arranged supports. Each support frame includes an upright frame 1 and a base frame 2. The upright frame 1 is set upright, and one end of the base frame 2 is vertically fixedly connected to the upright frame 1, forming an L-shaped support structure.

[0022] The top of the support frame corresponds to the extrusion process, which coats the surface of the sheet.

[0023] Between the two support frames, in the order in which the sheet passes, there are sequentially arranged receiving roller 3, positioning roller 4, intermediate roller 5, guide roller 6, adjusting roller 7, flipping roller 8, and support roller 9, all of which are arranged in parallel.

[0024] The layout and function of each roller are described in detail below:

[0025] The positioning roller 4 is installed at the top of the stand 1, and the guide roller 6 is installed at the bottom of the stand 1. The axes of the positioning roller 4 and the guide roller 6 are vertically aligned. The positioning roller 4 is used for coating (in conjunction with the coating head). The coating process is completed between the positioning roller 4 and the base head by passing the sheet material through the positioning roller 4. Therefore, the sheet material passes around the circumference of the positioning roller 4 away from the base 2, and also passes around the circumference of the guide roller 6 away from the base 2, forming an upward and downward stretching distance for the sheet material to unfold. Furthermore, by passing the sheet material around on the same side, the coated surface is always on the outer side (e.g., ...). Figure 1 As shown, it will not be damaged by contact.

[0026] The receiving roller 3 is mounted on the top of the support frame. It is positioned relative to the positioning roller 4 on the side facing the material in the feeding direction. The lower circumferential surface of the receiving roller 3 is used to wrap around the sheet material. Since the lower circumferential surface of the receiving roller 3 is lower than the upper circumferential surface of the positioning roller 4, the sheet material, after passing under the receiving roller 3 and wrapping around the positioning roller 4, can be effectively unfolded and tensioned from the upper circumferential surface of the positioning roller 4, allowing the sheet material to fully expand. Therefore, the receiving roller 3 plays a crucial role in receiving the incoming sheet material and cooperating with the positioning roller 4 to expand the sheet material.

[0027] The intermediate roller 5 is installed in the middle of the upright 1 to prevent the sheet from swaying. It mainly plays an auxiliary role. The side of the intermediate roller 5 away from the base frame 2 is coplanar with the side of the receiving roller 3.

[0028] The adjusting roller 7 and the flipping roller 8 are installed in a linkage manner, specifically:

[0029] A vertically extending mounting plate 12 is fixed on the base frame 2. A first sliding groove 10 and a second sliding groove 11, arranged parallel to each other in the same direction, are fixed on the mounting plate 12. The first sliding groove 10 and the second sliding groove 11 extend horizontally. The first sliding groove 10 is positioned above the second sliding groove 11 in height, thus the installation height of the adjusting roller 7 is lower than that of the flipping roller 8. The first sliding groove 10 and the second sliding groove 11 are staggered, with the first sliding groove 10 positioned closer to the upright frame 1. The other end of the first sliding groove 10 is close to the end of the second sliding groove 11 that is close to the upright frame 1, thereby ensuring that the staggered adjustment ranges of the adjusting roller 7 and the flipping roller 8 do not interfere with each other.

[0030] The first slide groove 10 is provided with a first slider 13 that is slidably connected thereto. The two ends of the flipping roller 8 are respectively rotatably connected to the first slider 13 on the same side, so that the flipping roller 8 has a displacement stroke in the horizontal direction.

[0031] The second slide groove 11 is provided with a second slider 14 that is slidably connected thereto. The two ends of the adjusting roller 7 are respectively rotatably connected to the second slider 14 on the same side, so that the adjusting roller 7 has a displacement stroke in the horizontal direction.

[0032] Based on the above structure, the spacing between the adjusting roller 7 and the flipping roller 8 can be adjusted in the horizontal direction at different heights, with the adjusting roller 7 at the bottom and the flipping roller 8 at the top.

[0033] In terms of distance control, a first fixing member 15 is fixed on the first slider 13, and a strip-shaped hole 16 for the first fixing member 15 to pass through is provided at the bottom of the first slide groove 10. A second fixing member is fixed on the second slider 14, and a strip-shaped hole 16 for the second fixing member to slide through is also provided at the bottom of the second slide groove 11. Two pulleys 18 are also mounted at the same height on the mounting plate 12. A spiral-shaped transmission belt 17 is wound between the pulleys 18. One of the pulleys 18 is driven by a motor. The transmission belt 17 is spirally wound around the two pulleys 18 and has an upper belt surface 19 and a lower belt surface 20. The first fixing member 15 is fixed on the upper belt surface 19, and the second fixing member is fixed on the lower belt surface 20. Thus, the relative distance between the flipping roller 8 and the adjusting roller 7 is controlled by the rotation of the transmission belt 17, allowing them to move away from each other to lengthen the buffer transition time, or move closer to each other to reduce the buffer transition time. This makes the time adjustable and extendable, avoiding the problem of insufficient surface material settling due to insufficient time.

[0034] The sheet material is wound from below the guide roller 6 to the adjusting roller 7, and after passing around the side of the adjusting roller 7 away from the stand 1, it is wound above the adjusting roller 7 to the flipping roller 8 (the side close to the stand 1), and is flipped for the first time when passing the flipping roller 8, so that the side coated with material comes into contact with the flipping roller 8.

[0035] The idler roller 9 is installed above the flipping roller 8 to support the guide sheet upwards, allowing the sheet to continue being fed to subsequent processes. Since the aforementioned buffered conveying process is a sunken structure, the high-position installation of the last idler roller 9 enables connection with other processes. Due to the different connection heights with other processes, lifting grooves 21 are provided at both ends of the idler roller 9. The bottom end of the lifting groove 21 is fixedly installed at the end of the base frame 2 away from the upright frame 1. A lifting slider 22 slides vertically within the lifting groove 21, and both ends of the idler roller 9 are rotatably connected to the lifting slider 22 on the same side. A lead screw 23 is installed through the lifting slider 22, and a lead screw 23 is vertically and rotatably installed within the lifting groove 21. The lead screw 23 cooperates with the lead screw nut and is driven by a motor. The motors on both sides are synchronized, making the height of the idler roller 9 adjustable and corresponding to the height of the conveying rollers in subsequent processes.

[0036] like Figure 1 As shown (the sheet is represented by a dashed line), the sheet first passes under the receiving roller 3, then passes over the positioning roller 4, and then passes the positioning roller 4, the intermediate roller 5 and the guide roller 6 in sequence on the side away from the base frame 2. After passing under the guide roller 6 and around the adjusting roller 7 (the side away from the upright frame 1), the sheet is flipped over after passing over the flipping roller 8, and finally supported and conveyed away from the mechanism by the support roller 9.

[0037] Based on the aforementioned structure and conveying mechanism, the roller layout mounted on the L-shaped support frame, through the folding utilization of downward space, provides ample buffer curing time for the coated surface of the sheet. This allows the sheet to receive buffer time during conveying without contact with the coated surface, up to the flipping roller 8. Furthermore, the adjustable distance between the adjusting roller 7 and the flipping roller 8 allows for further adjustment of the buffer time, providing sufficient curing time for the sheet and ensuring the coating quality.

[0038] Since the conveyor rollers described above are all sunkenly distributed and mounted on an L-shaped support frame, the rectangular three-dimensional space is utilized. To prevent contamination from dust and airborne impurities, a barrier can be further installed outside the support frame. This barrier covers the support frame, shielding the internal conveying process, thus preventing wind and dust, avoiding airflow interference with the sheet material, and preventing contamination of the freshly coated surface material. A cover or a transparent glass window can be installed on the top of the barrier to completely cover the coating and conveying process.

[0039] The enclosure can be made of rigid material or a frame with a flexible curtain (such as a transparent film) hanging on it, which facilitates observation of the interior, is easy to replace, and has a lower cost.
