Description

Technical Field

[0001] The invention belongs to the technical field of base sheet material production, and in particular relates to a cooling, forming and winding device for producing easily degradable starch-based sheet materials. Background Art

[0002] Degradable starch-based materials usually use starch as the main raw material and may contain other ingredients such as polyvinyl alcohol, polyethylene glycol, glycerol and hydroxypropyl methylcellulose. These materials are prepared by specific process methods, such as adding polyvinyl alcohol and hydroxypropyl methylcellulose to prepare high-strength starch-based fully degradable film special packaging materials. The use of starch-based materials helps reduce "white pollution", that is, environmental pollution caused by non-degradable plastic waste. These materials can be fully biodegradable, thereby reducing the impact on the environment; For example, the Chinese invention patent with publication number CN110562784B relates to a cloth-based tape traction and winding device, including a mounting platform, a driving device, a winding device and a clamping device. The driving device is installed on the left side of the upper end of the mounting platform, and the right end of the driving device is connected to the winding device. The clamping device is installed in the middle of the upper end of the mounting platform by welding, and the clamping device is located above the winding device. The cloth-based tape traction and winding device provided by the invention can solve the problems of tape adhesion, folding and wrinkling caused by sliding between the inner ring of the tape and the roller when the existing cloth-based tape winding device is wound, as well as the problems of bubbles inside the wound tape and the fluffy tape body after winding.

[0003] However, there are still some problems in actual use: In the existing production process of easily degradable starch-based sheets, there is a common problem: the base sheet is very easy to deform during the processing and winding stage. This is mainly because the temperature of the base sheet is high during the production process, and the subsequent cooling step adopts the traditional water cooling method. This method has a significant temperature difference between the surface and the inside of the base sheet due to the excessively fast cooling speed. The uneven distribution of this temperature difference causes uneven stress in the base sheet during the cooling process, which in turn causes warping, deformation, and even cracks. In addition, due to the uneven temperature distribution, the temperature difference between different parts of the base sheet is obvious, resulting in inconsistent viscosity. During the winding process, this difference in viscosity will cause uneven force, thereby affecting the winding quality and even causing further deformation of the base sheet.

[0004] Based on this, the present invention designs a cooling, forming and winding device for producing easily degradable starch-based sheets to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the base sheet is very likely to be deformed during the processing and winding stage, and to propose a cooling, forming and winding device for the production of easily degradable starch-based sheets.

[0010] As a further description of the above technical solution: The swing guide mechanism includes two support pins fixedly connected to the top wall of the cooling treatment frame, a guide plate is hinged between the two support pins, a sliding connection groove is opened on the side of the guide plate, and a connection bead is slidably connected in the sliding connection groove.

[0011] As a further description of the above technical solution: The connecting bead is fixedly connected to an intermediate rod outside, the other end of the intermediate rod is fixedly connected to a screw rod, the screw rod is externally threadedly connected to a threaded cap, the threaded cap is connected to the upper surface of the cooling treatment frame through, and one end of the screw rod located outside the cooling treatment frame is fixedly connected to a rotating plate.

[0012] As a further description of the above technical solution: The spraying mechanism includes a storage box fixedly connected to the outside of the cooling treatment frame, the side of the storage box is connected to a connecting pump, the side of the connecting pump is connected to an intermediate pipe, the other end of the intermediate pipe passes through the cooling treatment frame and is connected to a horizontal pipe, and a spray head is connected under the horizontal pipe.

The control switch is electrically connected to the connecting pump.

[0015] As a further description of the above technical solution: The air blowing cooling mechanism includes a connecting pipe that passes through and is connected to the outside of the cooling treatment frame. One end of the connecting pipe located in the cooling treatment frame is connected to a connecting pipe. An air outlet is provided outside the connecting pipe. A fixed sleeve is provided outside the connecting pipe. The fixed sleeve is fixedly connected to the outside of the cooling treatment frame. The side of the connecting pipe is connected to a fan assembly, and the fan assembly is fixedly connected to the outside of the cooling treatment frame.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 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 used. 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 efficient cooling and uniform molding of easily degradable starch-based sheets. The cooling treatment frame is cleverly divided into three different temperature zones to ensure the staged implementation of the cooling process. In the cooling system, the air blown out by the fan assembly on the far right directly contacts the high-temperature base sheet, effectively realizing heat exchange between the air and the base sheet. This design avoids the base sheet from being heated to high temperature. The sheet is directly impacted by the air with the lowest temperature, thereby reducing the risk of deformation caused by rapid cooling. The air heated by the base sheet flows to the left and contacts the base sheet that initially enters the cooling treatment frame. This method of circulating hot air ensures the gentleness and uniformity of the cooling process. Through this staged, multi-temperature zone cooling method, the device can ensure that the base sheet receives a more sufficient and uniform cooling treatment throughout the entire cooling process, effectively avoiding warping, deformation or cracking problems caused by excessive temperature differences, and significantly improving the production quality and winding efficiency of the base sheet.

[0017] 2. In the present invention, the first baffle, the second baffle, the third baffle and the fourth baffle are used. Since the gap between the first baffle and the base sheet is smaller than the gap between the second baffle and the base sheet, different pressure distributions are formed on the upper and lower sides of this area of ​​the base sheet, and the gap between the third baffle and the base sheet is larger than the gap between the fourth baffle and the base sheet, which also causes a pressure difference at another position of the base sheet. This pressure difference causes the base sheet to shake slightly to the left during the cooling process. This shaking action effectively shakes off impurities and debris on the surface of the base sheet, thereby improving the cleanliness of the base sheet. Combined with the airflow flowing out from the left side of the cooling processing frame, this design further enhances the cleaning effect on the surface of the base sheet, ensuring that the surface of the base sheet is clean before winding without impurities remaining.

[0018] 3. In the present invention, a connecting pump and a guide plate are used. The connecting pump effectively extracts and sprays the anti-sticking agent in the storage box, and is evenly coated on the upper and lower sides of the base sheet through the spray head. The airflow blowing obliquely along the guide plate promotes the uniform extension of the anti-sticking agent. This design cleverly utilizes the air flowing to the left, so that it blows directly on the anti-sticking agent on the surface of the base sheet, which not only ensures 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 a layer of anti-sticking film, effectively avoiding the uneven force and deformation problems of the base sheet due to uneven bonding during the winding process.

[0019] 4. In the present invention, a screw rod, a guide plate, a connecting bead, a sliding connecting groove and a supporting pin are used. By controlling the rotation of the screw rod, the movement of the connecting bead in the vertical direction is precisely controlled, and then the rotation of the guide plate is guided by the sliding connecting groove. The rotation of the guide plate is limited by the supporting pin, 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 base sheet, ensuring that the anti-sticking agent is evenly coated on the upper and lower sides of the base sheet. By reducing the gap between the base sheet and the guide plate, the air flow rate in the gap is improved, and air with different flow rates is used to generate different degrees of impact force on the anti-sticking agent, thereby achieving 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 handle base sheets 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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Specifically, Figure 2-4 As shown, a middle hole 17 is opened on the right side of the cooling treatment frame 7, and four pin shaft assemblies 18 are fixedly connected to the right side of the cooling treatment frame 7. A guide wheel 19 is hinged between the pin shaft assemblies 18 on the upper and lower sides, and the substrate passing through the middle hole 17 can pass through the gap between the two guide wheels 19.

[0025] The pin assembly 18 supports the guide wheel 19 so that the guide wheel 19 can rotate smoothly to support and guide the base sheet. The guide wheel 19 and the middle hole 17 can be used to guide and move the base sheet out of the cooling treatment frame 7 after cooling treatment, and prevent the base sheet in the cooling treatment frame 7 from shaking to the right.

[0026] Specifically, Figure 4-5 As shown, the positions of the first baffle plate 8 and the second baffle plate 9 correspond to each other, the positions of the third baffle plate 10 and the fourth baffle plate 11 correspond to each other, the distance between the first baffle plate 8 and the substrate passing through the cooling processing frame 7 is smaller than the distance between the second baffle plate 9 and the substrate, and the distance between the third baffle plate 10 and the substrate passing through the cooling processing frame 7 is greater than the distance between the fourth baffle plate 11 and the substrate.

[0027] The first baffle plate 8, the second baffle plate 9, the third baffle plate 10 and the fourth baffle plate 11 are used in cooperation to cleverly divide the cooling processing frame 7 into three different temperature zones. Since the space between the first baffle plate 8 and the base sheet is smaller than the space between the second baffle plate 9 and the base sheet, the pressures on the upper and lower sides of the base sheet are different at this position, and the space between the third baffle plate 10 and the base sheet is larger than the space between the fourth baffle plate 11 and the base sheet. At this position, the pressures on the upper and lower sides of the base sheet are different, resulting in the base sheet shaking to the left.

[0028] Specifically, Figure 5 As shown, the first baffle 8, the second baffle 9, the third baffle 10 and the fourth baffle 11 are all inclined toward the left side, the position of the air outlet net 13 is located between the inclined angles between the first baffle 8, the second baffle 9, the third baffle 10 and the fourth baffle 11 and the cooling treatment frame 7, and the swing guide mechanism 12 is located between the leftmost spray mechanism 14 and the third baffle 10.

[0029] Specifically, Figure 4-5 and Figure 7 As shown, the swing guide mechanism 12 includes two support pins 122 fixedly connected to the inner top wall of the cooling treatment frame 7, a guide plate 121 is hinged between the two support pins 122, a sliding connection groove 123 is provided on the side of the guide plate 121, and a connecting bead 124 is slidably connected in the sliding connection groove 123.

[0030] The connecting bead 124 is fixedly connected to an intermediate rod 125 on the outside, and the other end of the intermediate rod 125 is fixedly connected to a screw rod 126. The screw rod 126 is externally threadedly connected to a threaded cap 127. The threaded cap 127 is connected to the upper surface of the cooling treatment frame 7 through penetration, and one end of the screw rod 126 located outside the cooling treatment frame 7 is fixedly connected to a rotating plate 128.

[0031] The screw rod 126 can rotate to perform vertical movement in the threaded cap 127, thereby guiding the movement of the connecting bead 124. The connecting bead 124 slides in the sliding connecting groove 123, and the connecting bead 124 can maintain the connection with the sliding connecting groove 123, thereby realizing the extrusion adjustment of the guide plate 121. The guide plate 121 is limited by the support pin 122, so that the guide plate 121 can rotate stably, and the gap between the base sheet and the guide plate 121 is adjusted. The air flow rate in the gap is adjusted, and air with different flow rates is used to generate different degrees of impact force on the anti-sticking agent, thereby realizing fine adjustment of the thickness of the anti-sticking film.

[0032] Specifically, Figure 4-5 As shown, the spraying mechanism 14 includes a storage box 141 fixedly connected to the outside of the cooling treatment frame 7, the side of the storage box 141 is connected to a connecting pump 142, the side of the connecting pump 142 is connected to an intermediate pipe 143, the other end of the intermediate pipe 143 passes through the cooling treatment frame 7 and is connected to a transverse pipe 144, and a spray head 145 is connected below the transverse pipe 144.

[0033] The connecting pump 142 effectively extracts and sprays the anti-sticking agent in the storage box 141, and evenly coats it on the upper and lower sides of the base sheet through the spray head 145.

[0034] Specifically, Figure 5-6 and Figure 8 As shown, the movable control mechanism 15 includes a movable plate 151, and 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 network 13. Two connecting sleeves 153 are connected through the movable plate 151. A vertical rod 154 is slidably connected in the connecting sleeve 153. One end of the vertical rod 154 close to the cooling treatment frame 7 is fixedly connected to the cooling treatment frame 7.

[0035] An elastic component 156 is provided on the outer sleeve of the vertical rod 154, and the two ends of the elastic component 156 are respectively fixedly connected to the cooling treatment frame 7 and the connecting sleeve 153. The other end of the vertical rod 154 is fixedly connected to the limiting plate 155. A control switch 157 is provided under the movable plate 151. The control switch 157 is fixedly connected to the outside of the cooling treatment frame 7, and the control switch 157 is electrically connected to the connecting pump 142.

[0036] The air discharged into the cooling treatment frame 7 is sucked out by the fan assembly 165 and moved out through the air outlet net 13, so as to control the movement of the contact plate 152 and the movable plate 151, so as to control the movable plate 151 to move away from the cooling treatment frame 7. The control switch 157 automatically starts the connection pump 142 after it loses the pressing force, and the elastic force of the elastic assembly 156 is used to ensure that the movable plate 151 remains stable without being subjected to external force. Specifically, Figure 3-4 As shown, the air blowing cooling mechanism 16 includes a connecting pipe 161 that passes through and is connected to the outside of the cooling treatment frame 7. One end of the connecting pipe 161 located in the cooling treatment frame 7 is connected to a connecting pipe 162. An air outlet head 163 is provided outside the connecting pipe 162. A fixing sleeve 164 is provided outside the connecting pipe 161. The fixing sleeve 164 is fixedly connected to the outside of the cooling treatment frame 7. The side of the connecting pipe 161 is connected to a fan assembly 165. The fan assembly 165 is fixedly connected to the outside of the cooling treatment frame 7.

[0037] The fan assembly 165 sucks the external air and discharges it into the cooling treatment frame 7, and blows air to the upper and lower sides of the base sheet material to achieve a blowing cooling treatment for the base sheet material.

[0038] Working principle, when using: The processed base sheet is directly passed through the cooling treatment frame 7 and wound around the rotating winding drum 5, and the fan assembly 165 and the rotating winding drum 5 are controlled to rotate at the same time. The rotating winding drum 5 rotates to wind up the base sheet, and the fan assembly 165 draws outside air and blows it into the cooling treatment frame 7 through the connecting pipe 162 and the air outlet head 163. The upper and lower sides blow air to the upper and lower sides of the base sheet along the inclined angle, and the air flows to the left along the base sheet. As the space to the left of the cooling treatment frame 7 gradually decreases, the air blown out from the rightmost side contacts the base sheet, so that the air contacts the high-temperature base sheet. The heated air flowing to the left will contact the base of the base sheet that first enters the cooling treatment frame 7, so as to avoid the high-temperature base sheet from being contacted by the air with the lowest temperature, so that the cooling process is carried out in stages, and it is avoided that the base sheet cools too fast and the temperature difference between different parts in the cooling process is large. The gas flowing to the 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 base sheet is smaller than the space between the second baffle 9 and the base sheet, the pressures on the upper and lower sides of the base sheet are different at this position, and the space between the third baffle 10 and the base sheet is larger than the space between the fourth baffle 11 and the base sheet. At this position, the pressures on the upper and lower sides of the base sheet are different, which presents a situation where the base sheet shakes to the left. The shaking will cause the debris on the surface of the base sheet to be shaken and separated, and cooperate with the gas flowing out from the left side of the cooling treatment frame 7 to achieve a full cleaning effect on the surface of the base sheet; The increased air pressure in the cooling treatment frame 7 will flow out along the air outlet net 13, and the outflowing gas drives the contact plate 152 and the movable plate 151 to move away from the cooling treatment frame 7. At this time, the push switch loses its pressure, and the connection pump 142 is controlled to work. 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 base sheet through the spray head 145, and the air flowing to the left will be blown on the surface of the base sheet due to the inclination along the guide plate 121. The air blows on the surface of the anti-sticking agent on the surface of the base sheet, 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.
