Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a sheet molding equipment for plastic waterproofing materials. Background Technology

[0002] Concrete-faced rockfill dams are favored for pumped-storage power stations due to their safety, economy, and adaptability. Plastic sealing materials are specifically developed for sealing joints in concrete-faced rockfill dams. Domestic construction technology for plastic sealing materials on the top of the concrete face has advanced to a mechanized and rapid construction stage. Screw extruders are used as on-site construction equipment to directly extrude the plastic sealing material onto the joint surface into bulges of the required dimensions, greatly improving construction efficiency and saving labor costs.

[0003] Currently, plastic waterproofing materials are in block or rod shape and are solid materials. At low temperatures, due to their hardness, they can easily get stuck inside the screw extruder, leading to discontinuous bulging, excessive motor load, or even burnout. Therefore, a device is needed to pre-treat the plastic waterproofing materials so that the screw extruder can process them effectively. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a plastic waterproofing material sheet forming equipment to address the above-mentioned problems.

[0005] The technical solution adopted by this utility model is: a sheet molding device for plastic waterproofing material, comprising:

[0006] The support frame has unprocessed plastic water-stop material fed on its first end. The plastic water-stop material is conveyed and processed along the support frame from the first end to the second end.

[0007] The anti-adhesive material composite mechanism, located on the support frame, is used to cover the upper and lower surfaces of the plastic waterproofing material with its own internal anti-adhesive material;

[0008] The extrusion mechanism, located at the top of the support frame, is used to extrude the plastic waterproofing material wrapped with anti-adhesive material to form a sheet-like plastic waterproofing material.

[0010] Using the above-mentioned technical means, an anti-adhesive material composite mechanism is used to cover the unprocessed plastic waterstop material with an anti-adhesive material, and an extrusion mechanism is used to extrude the plastic waterstop material covered with the anti-adhesive material into a sheet. The resulting sheet plastic waterstop material is easy to process later, and can also be directly fed into the screw extruder after the anti-adhesive material is removed on the construction site. Because the formed sheet plastic waterstop material is relatively thin, it can be quickly formed after being fed into the screw extruder and is not easy to get stuck inside the screw extruder, so as to meet the construction needs.

[0011] In some embodiments, the support frame is provided with width adjustment components on both sides near the first end, which are used to adjust the width of the sheet-like plastic waterstop material.

[0015] In some embodiments, the traction assembly includes a first auxiliary traction roller and a second auxiliary traction roller. The top of the support frame is rotatably provided with the first auxiliary traction roller located at the output end of the extrusion mechanism. The top of the support frame is equipped with a plurality of parallel-arranged second auxiliary traction rollers at intervals via bearings. The ends of the first auxiliary traction roller and the second auxiliary traction roller are both connected to the drive control mechanism for transmission, so that the sheet-like plastic waterstop material output by the extrusion mechanism is output sequentially between the top of the first auxiliary traction roller, the top of the plurality of second auxiliary traction rollers, and a pair of tail support rollers.

[0016] In some embodiments, the extrusion mechanism includes a first extrusion roller, a second extrusion roller, and a transmission assembly. The first extrusion roller and the second extrusion roller are both rotatably mounted above the support frame via angle steel. The first end of the first extrusion roller is connected to the drive control mechanism, and the second end of the first extrusion roller is connected to the end of the second extrusion roller via the transmission assembly. Both the first extrusion roller and the second extrusion roller are solid cast iron rollers. The angle between the plane containing the axes of the first extrusion roller and the second extrusion roller and the top plane of the support frame is 45°. The roller surfaces of the first extrusion roller and the second extrusion roller are covered with a rubber layer.

[0017] In some embodiments, the transmission assembly includes a first transmission gear and a transmission wheel. The first transmission gear is a double gear, with a sprocket on the outer side and a spur gear on the inner side. The first end of the first extrusion roller is connected to the drive control mechanism. The second end of the first extrusion roller is equipped with a spur gear that can mesh with the inner spur gear of the first transmission gear. A sprocket is installed on the end of the second extrusion roller near the second end of the first extrusion roller. A transmission wheel is installed on the side wall of the support frame near the second end of the first extrusion roller. The sprocket on the outer side of the first transmission gear, the sprocket on the end of the second extrusion roller, and the transmission wheel are connected by the same chain.

[0018] In some embodiments, the drive control mechanism includes a gearbox, a variable frequency motor, and a control box. The variable frequency motor and the control box are communicatively connected. The control box is installed on the side wall of the support frame. The gearbox and the variable frequency motor are connected via belt drive. The gearbox is also connected to the first end of the first extrusion roller via a drive connection.

[0019] In some embodiments, the anti-adhesive material composite mechanism includes an upper anti-adhesive material support frame, an upper anti-adhesive material support shaft, a lower anti-adhesive material support frame, a lower anti-adhesive material support shaft, and an auxiliary support roller assembly. The lower anti-adhesive material support frame is installed at the first end of the support frame. The lower anti-adhesive material support shaft is rotatably mounted on the top of the lower anti-adhesive material support frame, and the lower anti-adhesive material is wound around the lower anti-adhesive material support shaft. The top of the support frame is provided with an auxiliary support roller assembly located between the lower anti-adhesive material support shaft and the extrusion mechanism. The upper anti-adhesive material... The support frame is installed above the middle of the support frame. The top of the upper anti-adhesive material support frame is rotatably equipped with an upper anti-adhesive material support shaft. The upper anti-adhesive material is wound on the upper anti-adhesive material support shaft, so that the lower anti-adhesive material on the lower anti-adhesive material support shaft can be guided into the extrusion mechanism by the auxiliary support roller group. The upper anti-adhesive material on the upper anti-adhesive material support shaft can be inserted into the extrusion mechanism from top to bottom. Thus, the upper anti-adhesive material and the lower anti-adhesive material cooperate to cover the upper and lower surfaces of the plastic water-stopping material entering the extrusion mechanism respectively.

[0020] The beneficial effects of this utility model are:

[0021] 1. An anti-adhesive material is applied to the unprocessed plastic waterstop material using an anti-adhesive composite mechanism. The plastic waterstop material is then extruded into sheet-like plastic waterstop material using an extrusion mechanism. Because the extruded sheet-like plastic waterstop material is relatively thin, it can maintain a certain degree of flexibility even at low temperatures, improving the workability of the material under low-temperature conditions and making it less likely to get stuck in the screw extruder. By folding the sheet-like material in half on-site and inserting it into the feed inlet, rapid extrusion molding is achieved, significantly improving construction efficiency and quality while ensuring the safe operation of the screw extruder motor.

[0022] 2. Due to the high viscosity and flexibility of plastic waterproofing materials, they easily adhere to other surfaces during the molding process. By covering the surface of the plastic waterproofing material with an anti-stick material, such as release paper, unnecessary adhesion between the plastic waterproofing material and the mold can be prevented, ensuring that the material can be smoothly removed from the mold without damage. At the same time, it prevents sheet materials from sticking together or becoming contaminated during transportation, and during construction, it is simple and convenient to use—simply peel off the release paper.

[0023] 3. The thickness and width of the plastic waterproofing material can be adjusted according to specific needs through the width adjustment component and the thickness adjustment component. Then, the cutting component can be used for precise cutting to meet different specifications and ensure smooth construction of the material under low temperature conditions.

[0030] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0032] Combination Figures 1 to 2As shown, this embodiment is a sheet forming device for plastic waterstop material, including a support frame 18, an anti-adhesive material composite mechanism, an extrusion mechanism, and a drive control mechanism 10. A plastic waterstop material mold (not shown) is provided at the first end of the support frame 18. The outlet of the plastic waterstop material mold can output unprocessed plastic waterstop material. The general conveying direction of the plastic waterstop material is from the first end to the second end of the top of the support frame 18. The support frame 18 is equipped with an anti-adhesive material composite mechanism and an extrusion mechanism. The input end of the extrusion mechanism corresponds to the outlet of the plastic waterstop material mold. The anti-adhesive material composite mechanism is used to cover the upper and lower surfaces of the plastic waterstop material with its own internal anti-adhesive material. The extrusion mechanism is used to extrude the plastic waterstop material wrapped with anti-adhesive material to form a sheet-like plastic waterstop material. The drive control mechanism 10 is located inside the support frame 18 and is connected to the extrusion mechanism. The drive control mechanism 10 is used to drive the extrusion mechanism.

[0033] Furthermore, the extrusion mechanism includes a first extrusion roller 6, a second extrusion roller 9, and a transmission assembly. The first extrusion roller 6 and the second extrusion roller 9 are both rotatably mounted on the support frame 18 via angle steel. The first end of the first extrusion roller 6 is connected to the drive control mechanism 10 via transmission, and the second end of the first extrusion roller 6 is connected to the end of the second extrusion roller 9 via the transmission assembly.

[0034] Specifically, in this embodiment, both the first extrusion roller 6 and the second extrusion roller 9 are solid cast iron rollers with a diameter of 30cm to 40cm. The angle between the plane where the axis of the first extrusion roller 6 and the second extrusion roller 9 is located and the top plane of the support frame 18 is 45°. The roller surfaces of the first extrusion roller 6 and the second extrusion roller 9 are covered with a 5mm thick rubber layer.

[0035] By wrapping a rubber layer around the extrusion roller, not only is the viscoelasticity of the plastic sealing material relaxed, but it also ensures that the rubber roller and the anti-stick material still have good friction and do not slip when the plastic sealing material is continuously exposed to high temperatures of 90℃~110℃.

[0036] Furthermore, in this embodiment, the transmission assembly includes a first transmission gear 7 and a transmission wheel 8. The first transmission gear 7 is a double gear, with a sprocket on the outer side and a spur gear on the inner side. The first end of the first extrusion roller 6 is connected to the drive control mechanism 10, and the second end of the first extrusion roller 6 is equipped with a spur gear that can mesh with the inner spur gear of the first transmission gear 7. A sprocket is installed on the end of the second extrusion roller 9 near the second end of the first extrusion roller 6, and a transmission wheel 8 is installed on the side wall of the support frame 18 near the second end of the first extrusion roller 6. The sprocket on the outer side of the first transmission gear 7, the sprocket at the end of the second extrusion roller 9, and the transmission wheel 8 are connected by the same chain drive.

[0037] Specifically, in this embodiment, the fixed position of the transmission wheel 8 can be adjusted up and down, thereby appropriately adjusting the chain tension caused by the change in the gap between the first extrusion roller 6 and the second extrusion roller 9.

[0038] Furthermore, the anti-adhesive material composite mechanism includes an upper anti-adhesive material support frame 13, an upper anti-adhesive material support shaft 12, a lower anti-adhesive material support frame 4, a lower anti-adhesive material support shaft 3, and an auxiliary support roller group 5. The lower anti-adhesive material support frame 4 is installed at the first end of the support frame 18. The lower anti-adhesive material support shaft 3 is rotatably mounted on the top of the lower anti-adhesive material support frame 4. The lower anti-adhesive material 2 is wound around the lower anti-adhesive material support shaft 3. The auxiliary support roller group 5 is located between the lower anti-adhesive material support shaft 3 and the input end of the extrusion mechanism at the top of the support frame 18. The auxiliary support roller group 5 is arranged at a slope. The upper anti-adhesive material support frame 13 is installed above the middle of the support frame 18. The top of the upper anti-adhesive material support frame 13 is rotatably provided with an upper anti-adhesive material support shaft 12. The upper anti-adhesive material 11 is wound around the upper anti-adhesive material support shaft 12, so that the lower anti-adhesive material 2 on the lower anti-adhesive material support shaft 3 can be guided into the extrusion mechanism by the auxiliary support roller group 5. The upper anti-adhesive material 11 on the upper anti-adhesive material support shaft 12 can be inserted into the extrusion mechanism from top to bottom. Thus, the upper anti-adhesive material 11 and the lower anti-adhesive material 2 cooperate to cover the upper and lower surfaces of the plastic water-stopping material entering the extrusion mechanism respectively.

[0039] By feeding the lower anti-stick material 2 on the lower anti-stick material support shaft 3 into the space between the first extrusion roller 6 and the second extrusion roller 9 through the top of the auxiliary support roller group 5, the auxiliary support roller group 5 can roll freely, reducing the friction of the lower anti-stick material 2 during the forward movement and providing support for the lower anti-stick material 2, preventing the lower anti-stick material 2 from being crushed by excessive weight at the feeding position.

[0040] Specifically, in this embodiment, both the upper anti-stick material 11 and the lower anti-stick material 2 are release paper.

[0041] In some embodiments, the support frame 18 is provided with width adjustment components 1 on both sides near the first end. The width adjustment components 1 are used to adjust the width of the sheet-like plastic waterstop material. The extrusion mechanism is provided with first thickness adjustment components 19 at both ends. The first thickness adjustment components 19 are used to adjust the thickness of the sheet-like plastic waterstop material. The top of the support frame 18 is provided with a traction component corresponding to the output end of the extrusion mechanism. The traction component is used to traction and transport the sheet-like plastic waterstop material and assist in forming the finished plastic waterstop material 17. The top of the support frame 18 near the second end is provided with a pair of tail support rollers 16 corresponding to the output end of the traction component. The traction component and the tail support rollers 16 are both connected to the drive control mechanism 10. The tail support rollers 16 are also provided with second thickness adjustment components 20 at both ends. The second thickness adjustment components 20 are used to adjust the thickness of the finished plastic waterstop material 17. The second end of the support frame 18 is also provided with a cutting component 21 corresponding to the output end of the second thickness adjustment component 20. The cutting component 21 is used to cut the finished plastic waterstop material 17 into segments.

[0042] Furthermore, the width adjustment component 1 includes at least one set of baffles, which are respectively installed on both sides of the support frame 18 via angle steel. The position of the baffles corresponds to the input port between the first extrusion roller 6 and the second extrusion roller 9. The width of the sheet-like plastic waterstop material extruded into the extrusion mechanism can be adjusted by adjusting the spacing of the set of baffles.

[0043] Furthermore, the first thickness adjustment component 19 and the second thickness adjustment component 20 include an extrusion rebound structure or a hydraulic lifting structure. In this embodiment, the extrusion rebound structure adopts a bolt-spring form, and the hydraulic lifting structure can be restored using hydraulic pressure. The thickness of the sheet-like plastic waterstop material or the finished plastic waterstop material 17 can be adjusted by adjusting the center distance between the rollers.

[0044] Furthermore, the traction assembly includes a first auxiliary traction roller 14 and a second auxiliary traction roller 15. The first auxiliary traction roller 14 is rotatably mounted on the top of the support frame 18 at the output end of the extrusion mechanism, and the first auxiliary traction roller 14 is located below the upper anti-adhesive material support shaft 12. Multiple parallel second auxiliary traction rollers 15 are installed at intervals on the top of the support frame 18 via bearings. The ends of the first auxiliary traction roller 14 and the second auxiliary traction roller 15 are both connected to the drive control mechanism 10, so that the sheet-like plastic waterstop material output by the first extrusion roller 6 and the second extrusion roller 9 is sequentially output between the top of the first auxiliary traction roller 14, the tops of the multiple second auxiliary traction rollers 15, and a pair of tail support rollers 16.

[0045] The traction section formed by the traction component provides a viscoelastic recovery buffer zone for the continuous sheet, making the continuous sheet less prone to breakage and wrinkling.

[0046] Specifically, in this embodiment, the first auxiliary traction roller 14 is a solid cast iron roller with a diameter of 22cm, and the second auxiliary traction roller 15 is a solid cast iron roller with a diameter of 6cm to 18cm. The roller spacing of the second auxiliary traction roller 15 is 0.5cm to 30cm. Figure 2 As shown, in this embodiment, cast iron pressure strips 26 with a cross-section of 1 / 2 to 1 / 3 of a circular arc and a diameter of 5 mm to 20 mm are symmetrically connected to the outer walls of a pair of tail support rollers 16. The cast iron pressure strips 26 are fastened to the outer wall of the rollers by countersunk bolts. When the cast iron pressure strips 26 on the pair of tail support rollers 16 rotate to correspond to each other, they are staggered.

[0047] The finished plastic waterstop material 17 is formed into a continuous sheet with uniform thickness by a pair of tail support rollers 16. The sheet is pressed with a positioning mark by the staggered extrusion of the cast iron pressure strips 26 on the tail support rollers 16. The finished plastic waterstop material 17 at the positioning mark is compressed to be relatively thin, which can produce the following effects: (1) It is convenient to carry out subsequent cutting operations along the mark, the cutting is flat and the cutting resistance is small; (2) Through the symmetrical arrangement of the cast iron pressure strips 26, after cutting along the mark, an independent sheet with a uniform width is formed, which is convenient for subsequent packaging; (3) The thickness at the cut is thin and the independent sheets are not easy to stick together.

[0048] Furthermore, the figure only shows the location of the cutting assembly 21. The cutting assembly 21 includes a conventionally used laser cutting device, which is installed at the top of the second end of the support frame 18. The laser cutting device is used to cut the finished plastic waterstop material 17 fed by the tail support roller 16. In this embodiment, the cutting assembly 21 can also be used to cut the plastic waterstop material using a utility knife.

[0049] Furthermore, the support frame 18 includes channel steel and angle steel. The support frame 18 is a two-layer structure formed by welding channel steel and angle steel, and its strength meets the requirements of the extrusion mechanism, drive control mechanism 10, subsequent products and packaging materials such as release paper.

[0050] In some implementations, the drive control mechanism 10 includes a gearbox 24, a variable frequency motor 25, and a control box. The variable frequency motor 25 is communicatively connected to the control box. The control box is installed on the side wall of the support frame 18. The variable frequency motor 25 and the gearbox 24 are installed inside the support frame 18. The variable frequency motor 25 and the gearbox 24 are connected by belt drive. The first end of the first extrusion roller 6, the first auxiliary traction roller 14, the second auxiliary traction roller 15, and the tail support roller 16 are all drive-connected to the gearbox 24.

[0051] Furthermore, a second transmission gear 22 is rotatably mounted inside the support frame 18, and a third transmission gear 23 is mounted at the output end of the reduction gearbox 24. Both the second transmission gear 22 and the third transmission gear 23 adopt a double gear structure, and both the inner and outer sides of the second transmission gear 22 and the third transmission gear 23 are sprockets. A sprocket is mounted at the first end of the first extrusion roller 6, and the sprocket at the first end of the first extrusion roller 6 is connected to the outer sprocket of the third transmission gear 23 via chain drive. Sprockets are mounted at the ends of the first auxiliary traction roller 14, the same side ends of the second auxiliary traction roller 15, and the same side ends of the tail support roller 16 at the bottom. The sprockets at the ends of the first auxiliary traction roller 14 and the second auxiliary traction roller 15 are connected to the outer sprocket of the second transmission gear 22 via the same chain drive, and the inner sprockets of the third transmission gear 23 and the inner sprockets of the second transmission gear 22 are connected to the sprocket at the end of the tail support roller 16 via the same chain drive. The other oriented ends of the pair of tail support rollers 16 are each provided with meshing spur gears.

[0052] Specifically, in this embodiment, the variable frequency motor 25 is a three-phase asynchronous motor with a power of 3kW to 10kW.

[0053] When the control box issues a start command, the variable frequency motor 25 starts to work. The variable frequency motor 25 drives the belt-driven reduction gearbox 24, and the output end of the reduction gearbox 24 drives the third transmission gear 23 to rotate.

[0054] Taking the clockwise rotation of the third transmission gear 23 as an example, since the outer sprocket of the third transmission gear 23 is connected to the first end chain of the first extrusion roller 6, the first extrusion roller 6 and the third transmission gear 23 rotate in the same direction. Since the second end of the first extrusion roller 6 is connected to the inner sprocket of the first transmission gear 7 via a sprocket, the first extrusion roller 6 drives the first transmission gear 7 to rotate synchronously, and the rotation directions of the first extrusion roller 6 and the first transmission gear 7 are opposite to each other. Since the outer sprocket of the first transmission gear 7, the sprocket at the end of the second extrusion roller 9, and the transmission wheel 8 are connected by a chain, the second extrusion roller 9 rotates synchronously. Among them, the first extrusion roller 6 is the driving roller, the second extrusion roller 9 is the driven roller, and the rotation directions of the first extrusion roller 6 and the second extrusion roller 9 are opposite, which can squeeze the fed plastic water-stopping material.

[0055] Because the inner sprocket of the third transmission gear 23, the inner sprocket of the second transmission gear 22, and the sprocket at the end of the tail support roller 16 are connected by a chain drive, they rotate synchronously in the same direction. Because the outer sprocket of the second transmission gear 22, the sprocket at the end of the first auxiliary traction roller 14, and the sprocket at the end of the second auxiliary traction roller 15 are connected by a chain drive, driven by the second transmission gear 22, they rotate in the same direction, completing the unidirectional conveying of the finished plastic waterstop material 17 at the top. For the pair of tail support rollers 16, the first end of the bottom tail support roller 16 is driven by the third transmission gear 23, and the second ends of the pair of tail support rollers 16 are meshed by corresponding spur gears, causing the pair of tail support rollers 16 to rotate in opposite directions, enabling the extrusion and output of the finished plastic waterstop material 17.

[0056] The implementation principle of the sheet molding equipment for plastic waterproofing material in this embodiment is as follows:

[0057] By covering unprocessed plastic sealing material with release paper, the plastic sealing material wrapped with release paper passes between the first extrusion roller 6 and the second extrusion roller 9, where it is compressed into a sheet-like plastic sealing material. Because plastic sealing material has high viscosity and flexibility, it easily adheres to other surfaces during the molding process. By covering the surface of the plastic sealing material with release paper, unnecessary adhesion between the plastic sealing material and the mold can be prevented, ensuring that the material can be smoothly removed from the mold without damage.

[0058] Meanwhile, when the material is output from the extrusion roller, it has a certain temperature and viscosity, making it prone to sticking to the underlying structure. The first auxiliary traction roller 14 and the second auxiliary traction roller 15 provide an auxiliary traction section for the forming sheet-like plastic waterstop material, creating a viscoelastic recovery buffer zone for the continuous sheet. This allows the material to cool slightly, reducing its viscosity and the risk of adhesion to the underlying structure. Finally, the second thickness adjustment component 20 further adjusts the thickness of the finished plastic waterstop material 17 to meet construction requirements.

[0059] The sheet forming equipment for plastic waterstop material in this embodiment can process unprocessed plastic waterstop material into sheet plastic waterstop material with a thickness of 3mm to 15mm, a width of 33cm, and a length of 90cm. Because the sheet plastic waterstop material formed by extrusion is relatively thin, it can maintain a certain degree of flexibility under low temperature conditions, which improves the workability of the material under low temperature conditions. This allows for on-site construction by simply tearing off the release paper, folding it in half along the width direction, and directly inserting it into the feed port of the screw extruder. It is not easy for the material to get stuck in the screw extruder, and construction can be carried out smoothly under low temperature conditions.

[0060] By adjusting the feeding distance before the extrusion rollers, the size, material, and inclined arrangement of the extrusion rollers, the elastic and viscous deformation of the plastic waterstop material is accommodated, extruding it into a continuous sheet with uniform width and thickness. The distance between the subsequent extrusion rollers and the traction rollers, as well as the synergistic traction effect of the traction rollers, further relaxes the elastic deformation of the plastic waterstop material and stabilizes the viscous deformation, forming a continuous sheet with stable dimensions. It will not tear or break due to elastic contraction deformation or continuous viscous flow deformation after being stretched.

[0061] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
