Description

Technical Field

[0001] The present invention belongs to the technical field of substrate production, and particularly relates to a cooling, forming and winding device for the production of degradable starch-based substrates. Background Art

[0002] Degradable starch-based materials usually use starch as the main raw material and may contain other components such as polyvinyl alcohol, polyethylene glycol, glycerol, and hydroxypropyl methylcellulose. These materials are prepared by specific process methods. For example, adding polyvinyl alcohol and hydroxypropyl methylcellulose to prepare a special packaging material for high-strength starch-based fully degradable films. The use of starch-based materials helps to reduce "white pollution", that is, environmental pollution caused by non-degradable plastic waste. These materials can be completely biodegradable, thus reducing the impact on the environment;

[0003] For example, the Chinese invention patent with the publication number CN110562784B relates to a cloth-based tape traction and winding device, including an installation table, a driving device, a winding device, and a pressing device. The driving device is installed on the left side of the upper end of the installation table, and the right end of the driving device is connected to the winding device. The pressing device is installed in the middle of the upper end of the installation table by welding, and the pressing device is located above the winding device. The cloth-based tape traction and winding device provided by this invention can solve problems such as tape adhesion, folding and wrinkling caused by sliding between the inner circle of the tape and the roller column during the winding of the existing cloth-based tape winding device, as well as the appearance of air bubbles inside the wound tape and the fluffiness of the tape body after winding.

[0004] However, in actual use, there are still some problems:

[0005] In the production process of existing degradable starch-based substrates, there is a common problem: the substrate is extremely prone to deformation during the processing and winding stage. This is mainly because the substrate has a relatively high temperature during the production process, and the subsequent cooling step uses a traditional water-cooling method. Due to the too-fast cooling speed, a significant temperature difference is generated between the surface and the interior of the substrate. This uneven distribution of the temperature difference causes uneven stress in the substrate during the cooling process, which in turn leads to warping, deformation, and even cracking. In addition, due to the uneven temperature distribution, the temperature difference between different parts of the substrate is obvious, resulting in inconsistent viscosity. During the winding process, this difference in viscosity causes uneven stress, which affects the winding quality and even leads to further deformation of the substrate.

[0006] Based on this, the present invention designs a cooling, forming and winding device for the production of degradable starch-based substrates to solve the above problems. Summary of the Invention

[0007] The object of the present invention is to propose a cooling forming and winding device for producing degradable starch-based substrates in order to solve the problem that the substrate is extremely prone to deformation during the processing and winding stage.

A fan assembly is communicated with the side surface of the connection pipe. The fan assembly is fixedly connected to the outside of the cooling treatment box.

[0028] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0029] 1. In the present invention, a cooling treatment frame, a fan assembly, a first baffle, a second baffle, a third baffle and a fourth baffle are adopted. The layout design of the cooling treatment frame, the fan assembly, and the first baffle, the second baffle, the third baffle and the fourth baffle realizes the efficient cooling and uniform forming of the biodegradable starch-based sheet. The cooling treatment frame is ingeniously divided into three different temperature zones, ensuring the phased implementation of the cooling process. In the cooling system, the air blown by the fan assembly on the far right directly contacts the high-temperature sheet, effectively realizing the heat exchange between the air and the sheet. This design avoids the direct impact of the lowest-temperature air on the sheet, thereby reducing the risk of deformation caused by rapid cooling. The air heated by the sheet flows to the left and contacts the sheet that initially enters the cooling treatment frame. This way of recycling hot air ensures the mildness and uniformity of the cooling process. Through this phased and multi-temperature-zone cooling method, the device can ensure that the sheet is more fully and uniformly cooled during the entire cooling process, effectively avoiding problems such as warping, deformation or cracking caused by excessive temperature difference, and significantly improving the production quality and winding efficiency of the sheet.

[0030] 2. In the present invention, a first baffle, a second baffle, a third baffle and a fourth baffle are adopted. Since the gap between the first baffle and the sheet is smaller than the gap between the second baffle and the sheet, different pressure distributions are formed on the upper and lower sides of the sheet in this area. The gap between the third baffle and the sheet is larger than the gap between the fourth baffle and the sheet, which also causes a pressure difference at another position of the sheet. This pressure difference causes the sheet to vibrate slightly to the left during the cooling process. This vibrating action effectively shakes off the impurities and debris on the surface of the sheet, improving the cleanliness of the sheet. Combined with the airflow flowing out from the left side of the cooling treatment frame, this design further strengthens the cleaning effect on the surface of the sheet, ensuring that the surface of the sheet is clean and free of impurity residues before winding.

[0031] 3. In the present invention, a connection pump and a guide plate are adopted. The connection pump effectively extracts and sprays the anti-sticking agent in the storage tank, and evenly coats it on the upper and lower sides of the sheet through a spraying head. The airflow blowing obliquely along the guide plate promotes the uniform extension of the anti-sticking agent. This design ingeniously utilizes the air flowing to the left and directly blows it on the anti-sticking agent on the surface of the sheet, not only ensuring the uniform distribution of the anti-sticking agent, but also the action of the high-temperature gas accelerates the drying and curing process of the anti-sticking agent. The anti-sticking agent can quickly and evenly form an anti-sticking film, effectively avoiding problems such as uneven stress and deformation caused by uneven adhesion during the winding process of the sheet.

[0032] 4. In the present invention, a lead screw, a guide plate, connecting beads, a sliding connection groove, and a support pin shaft are adopted. By controlling the rotation of the lead screw, the movement of the connecting beads in the vertical direction is precisely controlled. Then, the rotation of the guide plate is guided through the sliding connection groove, and the rotation of the guide plate is limited by the support pin shaft, ensuring the stability and accuracy of the adjustment. This design enables the device to flexibly adjust the position of the guide plate according to the different thicknesses of the substrate, ensuring that the anti-sticking agent is evenly coated on both the upper and lower sides of the substrate. By reducing the gap between the substrate and the guide plate, the air flow rate in the gap is increased, and different degrees of impact forces are generated on the anti-sticking agent by the air with different flow rates, thereby realizing the fine adjustment of the thickness of the anti-sticking film. This highly flexible adjustment mechanism not only improves the adaptability of the production line and can process substrates of various specifications, but also enhances the uniformity and controllability of the anti-sticking agent coating by controlling the air flow rate and impact force.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] Please refer to the attached Figure 1 - attached Figure 8 , the present invention provides a technical solution: a cooling forming and winding device for producing degradable starch-based sheets, including a chassis 1, two side supports 2 are fixedly connected to the upper surface of the chassis 1, a support shaft seat 3 is fixedly connected to the upper surface of the side support 2, a rotating winding drum 5 is rotatably connected inside the support shaft seat 3, a rotating fastening assembly 4 is arranged outside the support shaft seat 3, an extension rod 6 is fixedly connected to the side surface of the side support 2, the other end of the extension rod 6 is fixedly connected to a cooling treatment frame 7, a first baffle 8 and a third baffle 10 are fixedly connected to the inner top wall of the cooling treatment frame 7, a second baffle 9 and a fourth baffle 11 are fixedly connected to the inner bottom wall of the cooling treatment frame 7, two air outlet nets 13 are respectively arranged through the upper surface and the lower surface of the cooling treatment frame 7, swing guiding mechanisms 12 are arranged on both the inner top wall and the inner bottom wall of the cooling treatment frame 7, spraying mechanisms 14 penetrating and connecting outside the cooling treatment frame 7 are arranged on both the inner top wall and the inner bottom wall of the cooling treatment frame 7, a blowing and cooling mechanism 16 is penetrated and connected to the upper surface and the lower surface of the cooling treatment frame 7, the blowing and cooling mechanism 16 is fixedly connected to the front surface of the cooling treatment frame 7, and activity control mechanisms 15 are fixedly connected to the positions corresponding to the two air outlet nets 13 on the left side of the upper surface and the lower surface of the cooling treatment frame 7.

[0045] Specifically, as Figures 2 - 4 shown, an intermediate hole 17 is formed in the right side surface of the cooling treatment frame 7. Four pin shaft assemblies 18 are fixedly connected to the right side surface of the cooling treatment frame 7. A guide wheel 19 is hinged between the upper and lower pin shaft assemblies 18. The substrate passing through the intermediate hole 17 can pass through the gap between the two guide wheels 19.

[0046] The pin shaft assemblies 18 support the guide wheel 19, enabling the guide wheel 19 to rotate smoothly to support and guide the substrate. By using the guide wheel 19 and the intermediate hole 17, the substrate after being cooled by the cooling treatment frame 7 can be guided out, and the substrate in the cooling treatment frame 7 can be prevented from jittering to the right.

[0047] Specifically, as Figures 4 - 5 shown, the positions of the first baffle 8 and the second baffle 9 correspond to each other, and the positions of the third baffle 10 and the fourth baffle 11 correspond to each other. The distance between the first baffle 8 and the substrate passing through the cooling treatment frame 7 is smaller than the distance between the second baffle 9 and the substrate. The distance between the third baffle 10 and the substrate passing through the cooling treatment frame 7 is greater than the distance between the fourth baffle 11 and the substrate.

[0048] By using the cooperation of the first baffle 8, the second baffle 9, the third baffle 10 and the fourth baffle 11, the cooling treatment frame 7 is cleverly divided into three different temperature regions. Since the space between the first baffle 8 and the substrate is smaller than the space between the second baffle 9 and the substrate, the pressures on the upper and lower sides of the substrate are different at this position. The space between the third baffle 10 and the substrate is greater than the space between the fourth baffle 11 and the substrate, and the pressures on the upper and lower sides of the substrate are different at this position, presenting a situation where the substrate jitters to the left.

[0049] Specifically, as Figure 5 shown, the first baffle 8, the second baffle 9, the third baffle 10 and the fourth baffle 11 all incline towards the left. The position of the air outlet net 13 is between the inclined angles between the first baffle 8, the second baffle 9, the third baffle 10, the fourth baffle 11 and the cooling treatment frame 7. The swing guiding mechanism 12 is located between the spraying mechanism 14 at the leftmost side and the third baffle 10.

[0050] Specifically, as Figures 4 - 5 and Figure 7 shown, the swing guiding mechanism 12 includes two support pin shafts 122 fixedly connected to the inner top wall of the cooling treatment frame 7. The same guide plate 121 is hinged between the two support pin shafts 122. A sliding connection groove 123 is formed in the side surface of the guide plate 121. A connection bead 124 is slidably connected in the sliding connection groove 123.

[0051] The connecting bead 124 is externally fixedly connected with an intermediate rod 125. The other end of the intermediate rod 125 is fixedly connected with a lead screw 126. The lead screw 126 is externally threadedly connected with a threaded nut 127. The threaded nut 127 is connected through the upper surface of the cooling treatment frame 7. One end of the lead screw 126 located outside the cooling treatment frame 7 is fixedly connected with a rotating plate 128.

[0052] The rotation of the lead screw 126 can perform a vertical movement within the threaded nut 127 to realize the guiding movement of the connecting bead 124. The connecting bead 124 slides within the sliding connection groove 123, and the connecting bead 124 can maintain the connection with the sliding connection groove 123 to realize the extrusion adjustment of the guide plate 121. The guide plate 121 is limited by the support pin shaft 122 to enable the guide plate 121 to perform a stable rotation process, adjust the gap between the base sheet material and the guide plate 121, adjust the air flow rate in the gap, and use the air with different flow rates to generate different degrees of impact force on the anti-adhesive agent, thereby realizing the fine adjustment of the thickness of the anti-adhesive film.

[0053] Specifically, as Figures 4 - 5 shown, the spraying mechanism 14 includes a storage tank 141 fixedly connected outside the cooling treatment frame 7. A connecting pump 142 is communicated with the side surface of the storage tank 141. An intermediate pipe 143 is communicated with the side surface of the connecting pump 142. The other end of the intermediate pipe 143 penetrates through the cooling treatment frame 7 and is communicated with a cross pipe 144. A spraying head 145 is communicated with the lower part of the cross pipe 144.

[0054] The connecting pump 142 effectively extracts and sprays the anti-adhesive agent in the storage tank 141 and evenly coats it on the upper and lower sides of the base sheet material through the spraying head 145.

[0055] Specifically, as Figures 5 - 6 and Figure 8 shown, the movable control mechanism 15 includes a movable plate 151. A contact plate 152 is fixedly connected to one side of the movable plate 151 close to the cooling treatment frame 7. The contact plate 152 is arranged outside the air outlet net 13. Two connecting sleeves 153 are connected through the movable plate 151. A vertical rod 154 is slidably connected within the connecting sleeve 153. One end of the vertical rod 154 close to the cooling treatment frame 7 is fixedly connected with the cooling treatment frame 7.

[0056] An elastic component 156 is sleeved outside the vertical rod 154. Two ends of the elastic component 156 are respectively fixedly connected with the cooling treatment frame 7 and the connecting sleeve 153. A limiting plate 155 is fixedly connected to the other end of the vertical rod 154. A control switch 157 is arranged under the movable plate 151. The control switch 157 is fixedly connected outside the cooling treatment frame 7. The control switch 157 is electrically connected with the connecting pump 142.

[0057] The air exhausted into the cooling treatment box 7 is sucked by the fan assembly 165 and removed through the air outlet net 13. The contact plate 152 and the moving plate 151 can be controlled to move, so as to control the moving plate 151 to move away from the cooling treatment box 7. After the control switch 157 loses pressure, the connection pump 142 is automatically started to work. The elastic force of the elastic component 156 is used to ensure that the moving plate 151 remains stable without external force.

[0058] Specifically, as Figures 3 - 4 shown, the blowing and cooling mechanism 16 includes a connecting pipe 161 penetrating and connected outside the cooling treatment box 7. One end of the connecting pipe 161 located inside the cooling treatment box 7 is communicated with a communicating pipe 162. An air outlet head 163 is arranged outside the communicating pipe 162. A fixed sleeve 164 is sleeved outside the connecting pipe 161. The fixed sleeve 164 is fixedly connected outside the cooling treatment box 7. A fan assembly 165 is communicated with the side surface of the connecting pipe 161. The fan assembly 165 is fixedly connected outside the cooling treatment box 7.

[0059] The fan assembly 165 sucks external air and discharges it into the cooling treatment box 7, and blows the upper and lower sides of the substrate along the upper and lower sides to realize the blowing and cooling treatment of the substrate.

[0060] Working principle, when in use:

[0061] Directly pass the processed substrate through the cooling treatment box 7 and wind it around the rotating take-up reel 5. At the same time, control the rotation of the fan assembly 165 and the rotating take-up reel 5. The rotating take-up reel 5 rotates to wind up the substrate. The fan assembly 165 sucks external air and blows it into the cooling treatment box 7 through the communicating pipe 162 and the air outlet head 163. The upper and lower sides blow the upper and lower sides of the substrate along the inclined angle. The air flows left along the substrate. And because the space on the left side of the cooling treatment box 7 gradually decreases, the air blown out on the rightmost side contacts the substrate, realizing the contact between the air and the high-temperature substrate. And the air flowing left after being heated will contact the substrate that first enters the cooling treatment box 7, avoiding the contact between the high-temperature substrate and the air at the lowest temperature, making the cooling treatment process carried out in stages, and avoiding the situation that the substrate is cooled too fast and the temperature difference between different parts during the cooling process is large;

[0062] The gas flowing left will flow through the first baffle 8, the second baffle 9, the third baffle 10 and the fourth baffle 11. Since the space between the first baffle 8 and the substrate is smaller than the space between the second baffle 9 and the substrate, the pressure on the upper and lower sides of the substrate is different at this position. The space between the third baffle 10 and the substrate is larger than the space between the fourth baffle 11 and the substrate, and the pressure on the upper and lower sides of the substrate is different at this position, presenting a situation where the substrate shakes to the left. The shaking will cause the sundries on the surface of the substrate to be shaken off, and cooperate with the gas flowing out of the left side of the cooling treatment box 7 to achieve the effect of fully cleaning the surface of the substrate;

[0063] The increased air pressure in the cooling treatment box 7 will flow out along the air outlet net 13, and the flowing gas drives the contact plate 152 and the moving plate 151 to move away from the cooling treatment box 7. At this time, the pressing switch loses the pressing, and the control connection pump 142 works. The connection pump 142 sucks the anti-sticking agent in the storage box 141 and sprays it on the upper and lower sides of the substrate through the spraying head 145. Moreover, the air flowing to the left will be blown obliquely along the guide plate 121 on the surface of the substrate. The air blows on the surface of the anti-sticking agent on the substrate surface, so that the anti-sticking agent can be fully extended. And the high-temperature gas accelerates the drying and curing of the anti-sticking agent, so that the anti-sticking agent can quickly and evenly form an anti-sticking film.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
