Description

Technical Field

[0001] This utility model belongs to the field of decoration and construction technology, specifically relating to a device for processing and leveling silicone PU material plastic running tracks. Background Technology

[0002] Silicon PU (SPU) plastic running tracks are a type of sports field system with silicone-modified polyurethane as the core material. SPU consists of a single-component silicone-modified polyurethane (elastic layer) and a two-component modified acrylic (wear-resistant surface layer). It is mainly used in professional sports fields (such as basketball courts and tennis courts). In the construction of SPU plastic running tracks, the paving device is used as an auxiliary equipment for material spreading and surface treatment, while the scraper is the core execution unit of the paving device. Through multiple scraping and local pressure, it gradually makes up for thickness deviations, and the shearing force of the scraper promotes material compaction and leveling.

[0003] In existing silicone PU material plastic track processing and paving devices, when using a scraper to apply and pave the material, the material often dries and solidifies, adhering to the scraper. This requires soaking and cleaning with a special solvent. However, existing scrapers are mostly one-piece or riveted, making them difficult to disassemble. The adhered material needs to be soaked for a long time to soften, requiring multiple scrapers to be prepared for replacement during cleaning, which increases costs. Furthermore, long-term solvent soaking may corrode and damage the wooden or plastic ends of the scraper. Utility Model Content

[0004] The purpose of this invention is to provide a paving device for processing silicone PU plastic running tracks. This device can quickly remove the scraper from the inside of the installation end for replacement with a new scraper, without delaying the paving work and improving work efficiency. Furthermore, the removed scraper can be soaked and cleaned, which not only saves costs but also avoids solvent corrosion damage to the installation end.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A processing and paving device for silicone PU (PU) plastic running tracks includes a handle fixedly connected to the top of an installation end. A slidable insert box is provided inside the installation end. The bottom of the insert box has an open opening. A scraper is movably embedded inside the insert box, and the bottom of the scraper extends downwards to the outside of the installation end through the open opening. A T-shaped sliding plate is fixedly connected to the top of the insert box. A transverse through groove is formed inside the installation end for sliding and matching of the scraper, insert box, and T-shaped sliding plate. Insert rods are threaded to both ends of the insert box. The top of the scraper has embedded openings at both ends for inserting the rods. The insertion hole has a pull rod fixedly connected to both ends of the T-shaped slide plate. Positioning plates are fixedly connected to the bottom of both ends of the insertion box and on both sides of the scraper. A through hole is opened in the middle of the positioning plate. Two fastening screws are symmetrically provided on one side of the installation end. Two screw holes are opened in the inner side wall of the installation end. Pre-set installation holes are symmetrically opened in the outer wall of one side of the installation end. The two fastening screws pass through the pre-set installation holes and the through holes in sequence and are threaded to the two screw holes. The outer wall of the handle is provided with a scraping mechanism that can move and be positioned along its axis to scrape off residual material on the surface of the scraper.

[0007] Both ends of the mounting end and on both sides of the positioning plate are frictionally fitted with sealing blocks, and one end of the sealing block is provided with a slot for the pull rod to pass through.

[0008] The adjustable scraping mechanism includes a collar, which is slidably sleeved on the outer wall of the handle, and a fastening screw is movably inserted into the side wall of the collar.

[0009] The side wall of the handle is provided with a threaded hole for threaded connection with the fastening screw. Limiting rings are fixedly connected to the outer wall of the handle on the upper and lower sides of the collar to limit the movement of the collar.

[0010] The collar is symmetrically fixedly connected to a plumb line on its side wall. One end of the plumb line is slidably connected to an I-shaped sliding plate. The end of the plumb line near the I-shaped sliding plate is fixedly connected to the collar via a reinforcing rod.

[0011] The top of the I-shaped sliding plate near the scraper has a T-shaped groove, and a base plate is provided on one side of the T-shaped groove. The base plate is movably engaged with the T-shaped groove by a T-shaped retaining plate on the side wall.

[0012] A flat blade is fixedly connected to the bottom of the substrate, and rake blades are fixedly connected to the bottom of the substrate and on both sides of the flat blade. An adjusting screw is threaded to one end of the bottom of the vertical rod, and a magnetic suction plate is rotatably connected to the end of the adjusting screw near the flat blade.

[0013] The technical advantages achieved by this utility model are as follows: the scraper can be removed from the inside of the mounting end relatively quickly so that a new scraper can be replaced without delaying the paving work, thus improving work efficiency. Furthermore, the removed scraper can be soaked and cleaned, which not only saves costs but also avoids solvents from corroding and damaging the mounting end. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 , Figure 7 As shown, a processing and paving device for silicone PU plastic running tracks includes a handle 1 fixedly connected to the top of an installation end 2. A box 202 is slidably disposed inside the installation end 2. The bottom of the box 202 has an open opening. A scraper 201 is movably embedded inside the box 202, and the bottom of the scraper 201 extends downwards to the outside of the installation end 2 through the open opening. A T-shaped sliding plate 205 is fixedly connected to the top of the box 202. A transverse through groove is formed inside the installation end 2 for sliding and matching the scraper 201, the box 202, and the T-shaped sliding plate 205. Insert rods 203 are threadedly connected to both ends of the box 202. Insert holes 203 are embedded at both ends of the top of the scraper 201 for inserting the insert rods 203. 4. Pull rods 206 are fixedly connected to both ends of the T-shaped slide plate 205. Positioning plates 207 are fixedly connected to the bottom of both ends of the insertion box 202 and on both sides of the scraper 201. A through hole 208 is opened through the middle of the positioning plate 207. Fastening screws 209 are symmetrically provided on one side of the mounting end 2. A screw hole 211 is opened on the inner side wall of the mounting end 2. A preset mounting hole is symmetrically opened on the outer side wall of one side of the mounting end 2. The fastening screws 209 pass through the preset mounting hole and the through hole 208 in sequence and are threadedly connected to the screw hole 211. Sealing blocks 210 are frictionally fitted at both ends of the mounting end 2 and on both sides of the positioning plate 207. A groove for the pull rod 206 to pass through is opened at one end of the sealing block 210.

[0025] According to the above structure, the sealing block 210 is made of a material with a certain deformation capacity, such as rubber or silicone. The sealing block 210 is sealed and fitted at both ends of the mounting end 2 to prevent the paint from seeping into the interior of the mounting end 2. When the scraper 201 needs to be replaced, first pry off the sealing block 210, then rotate the second fastening screw 209 to separate one end from the second screw hole 211 and pull it out. At this time, the positioning plate 207 is not fixed, and the T-shaped sliding plate 205 engages and slides with the transverse through groove inside the mounting end 2. By pulling the pull rod 206, the T-shaped sliding plate 205 and the scraper 201 can be pulled out from the interior of the mounting end 2 as a whole. Rotate the insert rod 203 to separate it from the insert box 202 and remove it from the insertion hole 204. Without the obstruction of the insert rod 203, one end of the scraper 201 can be pulled out from the insert box 202. Install the new scraper 201 into the insert box 202 in the manner described above. Then slide the insert box 202 into the interior of the installation end 2. After the second fastening screw 209 passes through the through hole 208 and is screwed into the second screw hole 211, the replacement can be completed. After the replacement, one end of the scraper 201 is restricted by the engagement of the insert box 202 and the embedding of the insert rod 203. The two sides of the middle part of the scraper 201 are also clamped by the installation end 2, which enhances its firmness.

[0026] See attached document Figures 1-4, Figure 6 The outer wall of the handle 1 is provided with a scraping mechanism that can move and be positioned along its axial direction to scrape off residual material on the surface of the scraper 201. The adjustable scraping mechanism includes a collar 101, which is slidably sleeved on the outer wall of the handle 1. A fastening screw 102 is movably inserted into the side wall of the collar 101. A screw hole 103 is provided on the side wall of the handle 1 for threaded connection with the fastening screw 102. Limiting rings 104 are fixedly connected to the outer wall of the handle 1 and on the upper and lower sides of the collar 101 to limit the movement stroke of the collar 101. A vertical rod 105 is symmetrically fixedly connected to the side wall of the collar 101. An I-beam slide is slidably connected to one end of the bottom of the vertical rod 105. Plate 107, vertical rod 105 near one end of the I-beam slide plate 107 is fixedly connected to collar 101 via reinforcing rod 106. The top of the end of the I-beam slide plate 107 near scraper 201 is provided with T-slot 114. A base plate 108 is provided on one side of the T-slot 114. The base plate 108 is movably engaged with the T-slot 114 via T-slot 113 on the side wall. A flat blade 109 is fixedly connected to the bottom of the base plate 108. A rake blade 110 is fixedly connected to the bottom of the base plate 108 and on both sides of the flat blade 109. An adjusting screw 112 is threadedly connected to one end of the bottom of the vertical rod 105. A magnetic suction plate 111 is rotatably connected to the end of the adjusting screw 112 near the flat blade 109.

[0027] According to the above structure, before removing the scraper 201, the fastening screw 102 can be rotated to separate it from the screw hole 103. Then, the lower collar 101 is slid down until it is in contact with the limiting ring 104 at the lower end of the handle 1. Then, the reinforcing rod 106 is passed through the collar 101 and screwed into the screw hole 103 on one side of the limiting ring 104. At this time, the vertical rod 105 is located on both sides of the mounting end 2 as the collar 101 moves. The substrate 108 is then placed through the T... The T-shaped card plate 113 is inserted into the T-slot 114 from top to bottom. The bottom of the T-shaped card plate 113 is in contact with the middle of the I-shaped sliding plate 107, preventing the base plate 108 from moving laterally. Then, the base plate 108 is pushed to make the I-shaped sliding plate 107 slide laterally at one end of the vertical rod 105 until the flat blade 109 and the rake blade 110 approach and are attracted by the magnetic plate 111. It should be noted that the adjusting screw 112 must be made of non-magnetic metal, such as copper or 304 stainless steel, to avoid... The remaining magnetic plates 111 attract each other. Rotating the adjusting screw 112 drives the magnetic plates 111 to move axially, which can drive the flat blade 109 and the rake blade 110 to come close to the surface of the scraper 201. When the pull rod 206 is pulled to slide the scraper 201 out from the inside of the mounting end 2, the liquid material that has not yet solidified on the surface of the scraper 201 is scraped off by the flat blade 109 and the rake blade 110. The rake blade 110 allows some paint to pass through through the gap between the teeth, and initially scrapes off large or thick paint residues. The rake blade 110 then performs a second scraping and leveling. Through its continuous cutting edge, it can apply pressure evenly, eliminate tooth marks and form a smooth surface, thereby scraping the residue on the scraper 201 to the main material area on the ground. This can save raw materials and accelerate the soaking effect of the scraper 201. After scraping, the substrate 108 is directly pulled upward to separate it from the substrate 108. The substrate 108, the flat blade 109, the rake blade 110 and the scraper 201 can be put into the soaking tank together.

[0028] This invention allows for the quick removal of the scraper 201 from the interior of the mounting end 2, facilitating the replacement of a new scraper 201 without disrupting the paving work and improving efficiency. Furthermore, the removed scraper 201 can be soaked and cleaned, saving costs and preventing solvents from corroding or damaging the mounting end 2.

[0029] The working principle of this utility model is as follows: The sealing block 210 is made of a material with a certain deformation capacity, such as rubber or silicone. The sealing block 210 is sealed and fitted at both ends of the mounting end 2 to prevent the paint from seeping into the interior of the mounting end 2. When the scraper 201 needs to be replaced, the sealing block 210 is first removed, and then the second fastening screw 209 is rotated to separate one end from the second screw hole 211 and then pulled out. At this time, the positioning plate 207 is not fixed, and the T-shaped sliding plate 205 engages and slides with the transverse through groove inside the mounting end 2. By pulling the pull rod 206, the T-shaped sliding plate 205 and the scraper 201 can be pulled out from the interior of the mounting end 2 as a whole. By rotating the insert rod 203 to separate it from the insert box 202 and remove it from the insertion hole 204, without the obstruction of the insert rod 203, one end of the scraper 201 can be pulled out from the insert box 202. The new scraper 201 is then installed into the insert box 202 in the manner described above. The insert box 202 is then slidably embedded into the interior of the installation end 2. The replacement is completed by screwing the second fastening screw 209 through the through hole 208 and screwing it into the second screw hole 211. After the replacement is completed, one end of the scraper 201 is restricted by the locking of the insert box 202 and the embedding of the insert rod 203. The two sides of the middle part of the scraper 201 are also clamped by the installation end 2, which enhances its firmness.Before removing the scraper 201, the fastening screw 102 can be rotated to separate it from the screw hole 103. Then, the collar 101 is lowered until it is in contact with the limiting ring 104 at the lower end of the handle 1. The reinforcing rod 106 is then passed through the collar 101 and screwed into the screw hole 103 on one side of the limiting ring 104. At this time, the vertical rod 105 is located on both sides of the mounting end 2 as the collar 101 moves. The substrate 108 is then placed through the T-shaped clamp 11. 3. The T-shaped slot 114 is inserted from top to bottom, and the bottom of the T-shaped plate 113 is attached to the middle of the I-shaped sliding plate 107. The base plate 108 can no longer move laterally. Then, the base plate 108 is pushed to make the I-shaped sliding plate 107 slide laterally at one end of the vertical bar 105 until the flat blade 109 and the rake blade 110 approach and are attracted by the magnetic plate 111. It should be noted that the adjusting screw 112 must be made of non-magnetic metal, such as copper or 304 stainless steel, to avoid the presence of other magnetic materials. The suction plates 111 adhere to each other. Rotating the adjusting screw 112 moves the magnetic suction plate 111 axially, causing the flat blade 109 and rake blade 110 to come close to the surface of the scraper 201. When the pull rod 206 is pulled to slide the scraper 201 out from the inside of the mounting end 2, the unsolidified liquid on the surface of the scraper 201 is scraped off by the flat blade 109 and rake blade 110. The rake blade 110 allows some paint to pass through through the gaps between its teeth, initially scraping away large or thick paint residues. The rake blade 110 then performs a second scraping, applying pressure evenly through its continuous cutting edges to eliminate tooth marks and form a smooth surface. This scrapes the residue on the scraper 201 to the main material area on the ground, saving raw materials and accelerating the soaking effect of the scraper 201. After scraping, the substrate 108 is directly pulled upwards to separate it from the scraper. The substrate 108, flat blade 109, rake blade 110, and scraper 201 are then placed into the soaking tank together.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
