Description

Technical Field

[0001] The present invention relates to the technical field of carpet processing, in particular to a method and equipment for preparing a carpet tile. Background Art

[0002] Carpets are floor coverings made from materials such as cotton, wool, silk, linen, coconut coir, or chemical fibers. These include hand-tufted, machine-made, and hand-felt carpets. Broadly speaking, they also include mats, seat cushions, wall hangings, tents, saddle blankets, door curtains, and table rugs. During the Neolithic Age, people spun animal hair into yarn and wove it into thick, coarse woolen fabrics for floor coverings. Carpet fragments unearthed from Eastern Han Dynasty tombs in China are typical examples of hand-tufted carpets. During the Ming and Qing dynasties, while inheriting traditional carpet craftsmanship and incorporating the characteristics of brocade and embroidery, unique carpet designs with auspicious meanings were created, and these designs have been passed down through the ages.

[0003] Double-layer composite carpets are gradually replacing single-layer carpets due to their thickness and durability. The typical manufacturing steps for composite carpets are as follows: gluing and laminating the two layers of carpet stock; cutting the laminated carpets according to product requirements; sealing the cut carpets; and packaging the finished products. Traditional composite carpet production also has the following drawbacks:

[0004] First, when gluing and laminating double-layer carpets, the two carpet blanks may be misaligned. After lamination, the edges of the two carpet blanks are not aligned, resulting in an uneven appearance of the finished product, which ultimately reduces the production quality of the product.

[0005] Secondly, when double-layer carpets are pressed together, glue is applied, and the glue may be unevenly distributed during the spraying process. This can cause bulges and wrinkles on the upper and lower surfaces of the double-layer carpet after pressing, ultimately affecting the appearance of the finished product.

[0006] Third, if the amount of glue is too much during spraying, the glue may overflow from both sides of the double-layer carpet during pressing, causing the glue to flow on the side edges of the carpet. The glue condensed on the side edges of the carpet will affect the subsequent edge sealing process, and as the carpet is rolled up, the glue flowing on the side edges of the carpet will continue to drip onto the ground. When the glue condenses, glue marks that are difficult to remove will appear on the ground.

[0007] Therefore, it is necessary to provide a method and equipment for preparing a carpet tile to solve the above problems. Summary of the Invention

[0008] Based on this, it is necessary to provide a method and equipment for preparing a square carpet to address the existing technical problems.

[0042] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] refer to Figures 1 to 11 A method for preparing a carpet tile is shown, the method comprising the following steps:

[0044] S1, correcting the position of the carpet blank;

[0045] The finished carpet is made of two pieces of carpet blanks pressed together. In order to make the pressed carpet look neat, one of the carpet blanks is corrected before the two carpet blanks are pressed together so that the two carpets can overlap each other without misalignment.

[0046] S2, pressing the carpet blanks;

[0047] During the pressing process, glue is sprayed between the two carpet blanks to make the two carpets adhere to each other into one body. The glue spraying machine used for spraying the glue is existing technology and is not shown in the figure.

[0048] S3, flattening the pressed carpet;

[0049] In order to make the surface of the finished carpet smooth and prevent wrinkles, the carpet is flattened after pressing.

[0050] S4, removing glue from two side edges of the flattened carpet;

[0051] During the flattening process, unsolidified glue will be squeezed to both sides of the carpet blank. In order to prevent the glue from solidifying on the sides of the carpet and affecting the subsequent edge banding process, it is necessary to remove the glue from the two sides of the flattened carpet.

[0052] S5, rolling up the carpet after the above steps;

[0053] The pressed carpet is rolled up to facilitate transportation between production lines. The winding machine used for rolling up is existing technology and is not shown in the figure.

[0054] During the carpet rolling process, the carpet is corrected, pressed, flattened and the glue on the sides is removed in sequence.

[0055] S6, cutting the carpet into squares;

[0056] The rolled carpet is cut according to production requirements, and the cut scraps are collected. The cutting machine used for cutting is existing technology and is not shown in the figure.

[0057] S7, edge sealing the cut carpet.

[0058] The four edges of the cut carpet are sealed to make the carpet more beautiful and prevent the corners of the carpet from being easily broken. The edge sealing machine used in the edge sealing is existing technology and is not shown in the figure.

[0059] A square carpet preparation device includes a correction component, a pressing mechanism, a flattening mechanism and two sets of side glue removal components. The correction component includes a correction roller 1, which is used to fine-tune the position of the carpet blank located above so that the upper and lower carpet blanks completely overlap. The pressing mechanism includes two pressing rollers 2 that press the two carpet blanks together by rotating in opposite directions. The flattening mechanism includes two flattening rollers 3 that flatten the pressed carpet from the middle to the sides by rotating in opposite directions. Each set of side glue removal components includes an oblique scraper 4 and a reciprocating scraping mechanism. The oblique scraper 4 is in a fixed state and is used to scrape off glue overflowing from the corresponding side of the carpet in real time. The reciprocating scraping mechanism includes a composite scraper, a telescopic mechanism, a driving member and a collection bucket 5. The composite scraper includes a long scraper 6, a short scraper 7 and a movable scraper bar 8. The long scraper 6 and the short scraper 7 are both in an inclined fixed state. The composite scraper is driven to rise and fall back and forth by a driving member. The long scraper 6 is used to scrape the glue accumulated on the oblique scraper 4 when rising, and lead the scraped glue to the collecting bucket 5. The telescopic mechanism is used to drive the movable scraper bar 8 to retract laterally after the movable scraper bar 8 rises and falls. The movable scraper bar 8 is in a retracted state when rising, and in an extended state when descending. When the movable scraper bar 8 is extended, it is used to scrape the glue on the oblique scraper 4 downward into the collecting bucket 5. When the movable scraper bar 8 retracts, the short scraper 7 scrapes the glue on the movable scraper bar 8, and leads the scraped glue to the collecting bucket 5 through the short scraper 7.

[0060] During the process of correcting the deviation of the two carpets and then pressing them together, the carpet at the bottom passes horizontally directly through the two pressing rollers 2, while the carpet at the top first passes over the deflection-correcting roller 1 and then passes between the two pressing rollers 2. When installed, the deflection-correcting roller 1 needs to be higher than the pressing roller 2 at the top, so that there is a height difference between the deflection-correcting roller 1 and the pressing roller 2. This height difference creates an opening between the two carpets, through which the glue sprayer sprays glue into the space between the two carpets.

[0061] The upper carpet will be corrected by the correction roller 1 when passing through it, so that the upper and lower carpets are completely overlapped before pressing, preventing the two carpets from being misaligned and causing the quality of the pressed product to be substandard.

[0062] Before the two carpets pass through the pressing mechanism, the glue sprayer sprays glue between the two carpets, and then the two carpets are pressed up and down by the rotation of the two pressing rollers 2;

[0063] After the two carpets are pressed together, they pass through the flattening mechanism. At this time, the two flattening rollers 3 will flatten the upper and lower surfaces of the carpet from the middle to the sides to ensure that the carpet surface is flat;

[0064] When the carpet is flattened, the unsolidified glue will be squeezed to the sides of the carpet, causing the glue to flow on the sides of the carpet. The glue solidified on the sides of the carpet will affect the subsequent edge sealing process. As the carpet is rolled up, the glue flowing on the sides of the carpet will continue to drip onto the floor. When the glue solidifies, glue marks will be left on the floor that are difficult to remove. Therefore, the two sets of side glue removal components of this device are used to remove glue from the two sides of the carpet in real time.

[0065] First, the oblique scraper 4 is used to scrape off the glue hanging on the side of the carpet in real time, and then the reciprocating scraping mechanism of the device is used to scrape off the glue accumulated on the oblique scraper 4. During this process, the driving member drives the composite scraper to rise and fall back. Before the composite scraper falls, the movable scraper 8 is extended through the telescopic mechanism and scrapes the glue on the oblique scraper 4 downward into the collecting bucket 5 when it falls. When the composite scraper rises, the long scraper 6 will scrape off the glue on the oblique scraper 4 and pass through the long scraper 6. The scraped glue liquid is led into the collecting bucket 5. Before the composite scraper rises, the movable scraper 8 is in a retracted state through the telescopic mechanism. Then, during the retraction of the movable scraper 8, the short scraper 7 will scrape the glue liquid on the movable scraper 8, and the scraped glue liquid is led into the collecting bucket 5 through the short scraper 7. In summary, the oblique scraper 4 can realize real-time scraping of the glue liquid hanging on the side of the carpet while preventing the glue liquid from accumulating on the oblique scraper 4 and the movable scraper 8 and affecting the scraping effect of the two.

[0066] In order to show the specific installation method of the oblique scraper 4 and the collecting bucket 5 and the specific structural state of the composite scraper, the following features are specifically set:

[0067] A No. 1 support platform 9 is fixed on both sides of the carpet. Each oblique scraper 4 forms a 45° angle with the corresponding side of the carpet, and each oblique scraper 4 is fixedly connected to the No. 1 support platform 9. Each collecting bucket 5 is fixedly connected to the No. 1 support platform 9, and each collecting bucket 5 is located below the corresponding oblique scraper 4. The upper end of each long scraper 6 is formed with a No. 1 shovel-shaped surface 10 that fits the scraping surface of the oblique scraper 4. The other end of each long scraper 6 is away from the oblique scraper 4. Each movable scraper bar 8 is perpendicular to the The scraping surface of the oblique scraper 4, and one end of each movable scraper 8 is a tip that conflicts with the scraping surface of the oblique scraper 4, one end of each short scraper 7 is connected to the side of the corresponding long scraper 6 facing the oblique scraper 4, the other end of each short scraper 7 is inclined toward the oblique scraper 4, and each short scraper 7 is formed with a No. 2 shovel-shaped surface 11 at one end facing the oblique scraper 4 that fits the bottom surface of the movable scraper 8. The telescopic mechanism is arranged on the side of the oblique scraper 4, and the driving member is arranged below the telescopic mechanism.

[0068] Before the composite scraper descends, the movable scraper bar 8 is extended through the telescopic mechanism. At this time, the tip of the movable scraper bar 8 will conflict with the scraping surface of the oblique scraper 4. Then, during the descending process, the movable scraper bar 8 will scrape the glue on the oblique scraper 4 downward into the collecting bucket 5. When the composite scraper rises, the No. 1 shovel-shaped surface 10 on the long scraper plate 6 will fit the scraping surface of the oblique scraper plate 4 and slide upward to scrape the glue accumulated on the scraping surface of the oblique scraper plate 4. The scraped glue will flow downward along the long scraper plate 6 and finally flow into the collecting bucket 5. Before the composite scraper rises, the movable scraper bar 8 is retracted through the telescopic mechanism. Then, during the retraction process, the No. 2 shovel-shaped surface 11 on each short scraper plate 7 will fit the bottom surface of the movable scraper bar 8 and slide to scrape off the glue on the movable slide bar. Finally, the scraped glue will be led into the collecting bucket 5 through the end scraper.

[0069] In order to show the specific structure of the telescopic mechanism and the driving parts, the following features are set:

[0070] Each telescopic mechanism includes a connecting plate 12, a connecting bar 13, a sliding bar 14, two sets of oblique wedge interference mechanisms and two sets of magnetic fixing mechanisms. The connecting plate 12 is parallel to the corresponding oblique scraper 4, and the connecting plate 12 is arranged in parallel along the length direction of the oblique scraper 4. The connecting plate 12 is fixedly connected to the oblique scraper 4, and the connecting bar 13 is horizontally across the connecting plate 12. The two ends of the connecting bar 13 correspond to the two ends of the connecting plate 12 respectively. The connecting bar 13 is spaced from the connecting plate 12, and both ends of the connecting bar 13 are formed with end bars 15 perpendicular to it. Each end bar 15 is provided with a bar slide 16, and the length direction of each bar slide 16 is consistent with the length direction of the corresponding end bar 15. The sliding bar 14 is provided between the connecting bar 13 and the connecting plate 12, and both ends of the sliding bar 14 are formed with sliders 17. The sliders 17 slide in the two strip-shaped slide grooves 16 respectively, one end of each movable scraper 8 is fixedly connected to one of the sliders 17, and one end of each long scraper 6 is fixedly connected to one end of the corresponding connecting bar 13. The driving member is the No. 1 telescopic cylinder 18, and the No. 1 telescopic cylinder 18 is fixedly arranged on the No. 1 support platform 9 in a vertical state. The output end of the No. 1 telescopic cylinder 18 is upwardly fixed to the bottom of the connecting bar 13, and the two sets of inclined wedge interference mechanisms are used to drive the sliding bar 14 to slide away from the oblique scraper 4 at the final stage of the descent of the connecting bar 13, and to drive the sliding bar 14 to slide toward the oblique scraper 4 at the final stage of the ascent of the connecting bar 13. The two sets of magnetic fixing mechanisms are used to limit the sliding stroke of the two sliders 17, and after the sliding of the two sliders 17 is completed, each slider 17 is temporarily fixed to the corresponding end bar 15 by magnetic attraction.

[0071] The output end of the No. 1 telescopic cylinder 18 reciprocates and retracts. When the No. 1 telescopic cylinder 18 drives the connecting bar 13 to rise, the connecting bar 13 will drive the long scraper 6 connected thereto to slide upward, thereby scraping the glue on the oblique scraper 4 by sliding the long scraper 6 upward. After the connecting bar 13 rises for a period of time, the sliding bar 14 will slide toward the oblique scraper 4 through two sets of oblique wedge friction mechanisms, so that the slider 17 formed on one end of the sliding bar 14 will drive the movable scraper 8 to slide toward the oblique scraper 4 until the tip of the movable scraper 8 fits with the scraping surface of the oblique scraper 4. At the same time, after the sliding of the slider 17 is completed, it is adsorbed and fixed to the corresponding end bar 15 by the magnetic fixing mechanism. Then, when the No. 1 telescopic cylinder 18 drives the connecting bar 13 to descend, the sliding bar 14 will descend stably. At this time, the glue on the oblique scraper 4 is scraped off by the movable scraper bar 8. Since the sliding bar 14 is temporarily fixed to the end bar 15 by magnetic attraction when it descends, the movable scraper bar 8 will not slide laterally when it descends, ensuring that the movable scraper bar 8 can descend stably. After the movable scraper bar 8 has dropped to one end, the sliding bar 14 will overcome the magnetic attraction force and slide away from the oblique scraper 4 through the two sets of oblique wedge friction mechanisms, so that the movable scraper bar 8 will follow the sliding bar 14 to retract, and finally, during the retraction process of the movable scraper bar 8, the glue on the movable scraper bar 8 will be scraped off by the short scraper 7, and after the retraction of the sliding bar 14 is completed, it will be magnetically fixed to the corresponding end bar 15 again by the magnetic fixing mechanism, so that when the No. 1 telescopic cylinder 18 drives the connecting bar 13 to rise again, the movable scraper bar 8 will be in a stable rising state.

[0072] In order to show the specific structure of the wedge interference mechanism, the following features are set:

[0073] Each set of inclined wedge conflict mechanisms includes a parallelogram block 19, a No. 1 conflict bar 20, and a No. 2 conflict bar 21. The parallelogram block 19 is located outside the connecting bar 13 and the parallelogram block 19 is fixedly connected to the corresponding slider 17. The No. 1 conflict bar 20 and the No. 2 conflict bar 21 in each set of inclined wedge conflict mechanisms are fixed on the same side of the connecting plate 12, wherein the No. 1 conflict bar 20 is close to the bottom of the connecting plate 12, and the No. 2 conflict bar 21 is close to the top of the connecting plate 12. The No. 1 interference strip 20 is fixed in a vertical state on the corresponding side of the connecting plate 12, and the No. 2 interference strip 21 is L-shaped, with its vertical end facing downward and its horizontal end fixed on the corresponding side of the connecting plate 12. The upper end of the No. 1 interference strip 20 is formed with a No. 1 oblique wedge end 22 that is wedge-matched with one of the acute-angled ends of the parallelogram block 19, and the vertical end of the No. 2 interference strip 21 is formed with a No. 2 oblique wedge end 23 that is wedge-matched with the other acute-angled end of the parallelogram block 19.

[0074] When the No. 1 telescopic cylinder 18 drives the connecting bar 13 to move downward, each parallelogram block 19 will move toward the corresponding No. 1 contact bar 20. Thereafter, one of the acute-angled ends of the parallelogram block 19 will downwardly contact the No. 1 oblique wedge end 22 at the upper end of the No. 1 contact bar 20. As a result, the parallelogram block 19 will move away from the oblique scraper 4 due to the friction. Finally, the sliding bar 14 will drive the movable scraper 8 to retract. During the retraction process, the glue on the movable scraper 8 is scraped off by the short scraper 7.

[0075] When the No. 1 telescopic cylinder 18 drives the connecting bar 13 to move upward, each parallelogram block 19 will move toward the corresponding No. 2 interference bar 21. After that, the other acute-angled end of the parallelogram block 19 will upwardly conflict with the No. 2 oblique wedge end 23 on the vertical end of the No. 2 interference bar 21. As a result, the parallelogram block 19 will move toward the oblique scraper 4 due to the conflict. Finally, the sliding bar 14 will drive the movable scraper 8 to extend, so that in the subsequent descending process, the glue on the oblique scraper 4 will be scraped off by the movable scraper 8.

[0076] In order to show the specific structure of the magnetic fixing mechanism, the following features are specifically set:

[0077] Each set of magnetic fixing mechanisms includes a No. 1 magnetic block 24 and a No. 2 magnetic block 25 fixed in the strip-shaped slide groove 16, wherein the No. 1 magnetic block 24 is close to the oblique scraper 4, the No. 2 magnetic block 25 is close to the connecting bar 13, and the slider 17 is located between the No. 1 magnetic block 24 and the No. 2 magnetic block 25. Magnets 26 are fixed on both sides of each slider 17, and the two magnets 26 cooperate with the No. 1 magnetic block 24 and the No. 2 magnetic block 25 respectively.

[0078] When the parallelogram block 19 is abutted by the No. 1 beveled wedge end 22, the slider 17 will overcome the magnetic force between the magnet 26 and the No. 2 magnetic block 25 and slide toward the No. 1 magnetic block 24. After that, the slider 17 is magnetically fixed to the No. 1 magnetic block 24 through the corresponding magnet 26. At this time, the movable scraper 8 is driven out by the sliding bar 14, and the movable scraper 8 is temporarily restricted in lateral displacement. When the parallelogram block 19 is abutted by the No. 2 beveled wedge end 23, the slider 17 will overcome the magnetic force between the magnet 26 and the No. 1 magnetic block 24 and slide toward the No. 2 magnetic block 25. After that, the slider 17 is magnetically fixed to the No. 2 magnetic block 25 through the corresponding magnet 26. At this time, the movable scraper 8 is driven to retract by the sliding bar 14, and during the retraction process, the glue on the movable scraper 8 is scraped off by the short scraper 7.

[0079] In order to prevent the glue liquid on the long scraper 6 from flowing sideways, the following features are specifically set:

[0080] A plurality of guide grooves 27 evenly distributed along the length direction of each long scraper 6 are formed on a surface of each long scraper 6 facing away from the oblique scraper 4 .

[0081] The glue liquid on the long scraper 6 is directly introduced downward into the collecting hopper 5 through a number of guide grooves 27 to prevent the glue liquid from flowing sideways;

[0082] In order to further prevent the glue from flowing out from both sides of the long scraper 6, a side baffle (not shown in the figure) can be fixed on both sides of the long scraper 6 when processing the long scraper 6, and the side baffle can be used to prevent the glue from flowing out from both sides of the long scraper 6.

[0083] In order to show the specific structure of the correction component, the following features are set:

[0084] A No. 2 support platform 28 is provided at both ends of the correcting roller shaft 1. The correcting assembly also includes two sets of displacement mechanisms, each set of displacement mechanisms includes a screw slide 29 and an L-shaped connecting block 30. The screw slide 29 is fixed on the No. 2 support platform 28. The displacement direction of the output end of the screw slide 29 is at a 45° angle to the axial direction of the correcting roller shaft 1. A vertical upward fixed shaft 31 is formed on the output end of the screw slide 29. The horizontal end of the L-shaped connecting block 30 is rotatably connected to the fixed shaft 31. The two ends of the correcting roller shaft 1 are respectively axially connected to the vertical ends of the two L-shaped connecting blocks 30. A No. 2 telescopic cylinder 32 is fixed on one of the screw slides 29 for driving the output end of the current screw slide 29 to displace.

[0085] The output end of one of the screw slides 29 is displaced by the second telescopic cylinder 32, causing the axial direction of the correction roller shaft 1 to deflect, thereby changing the direction of the carpet blank located above, ultimately ensuring that the two carpet blanks completely overlap;

[0086] In order to further achieve precise control of the position of the carpet blanks, a distance sensor (not shown in the figure) is fixedly set on one of the side edges of the two carpet leathers, and the two distance sensors are on the same horizontal line. The values ​​measured by the two distance sensors are the distances from the output ends of the distance sensors to the corresponding carpet sides, so that the two sets of values ​​can be compared. If the two sets of values ​​are different, the second telescopic cylinder 32 will continue to extend and retract to fine-tune the deflection of the correction roller shaft 1 until the two sets of values ​​are consistent. At this time, the upper and lower carpet blanks are completely overlapped.

[0087] In order to show the specific structure of the pressing mechanism, the following features are set:

[0088] The axial direction of each laminating roller 2 is horizontal, and the upper and lower laminating rollers 2 are parallel to each other. Both ends of each laminating roller 2 are connected to the corresponding No. 1 support platform 9 through the No. 1 shaft seat 33. The laminating mechanism also includes two No. 1 gears 34, which are coaxially fixed to one end of the two laminating rollers 2 respectively, and the two No. 1 gears 34 are meshed with each other.

[0089] An external driving source (not shown in the figure) is connected to one end of one of the pressing rollers 2, which is used to drive the corresponding pressing roller 2 to rotate. The two pressing rollers 2 are driven towards each other through the transmission of the two No. 1 gears 34, and finally the two carpets are pressed up and down by the opposite rotation of the two pressing rollers 2.

[0090] In order to show the specific structure of the flattening mechanism, the following features are set:

[0091] The axial direction of each flattening roller 3 is horizontal, and the upper and lower flattening rollers 3 are parallel to each other. Both ends of each flattening roller 3 are connected to the corresponding No. 1 support platform 9 through the No. 2 shaft seat 38. The flattening mechanism also includes two No. 2 gears 35, which are coaxially fixed to one end of the two flattening rollers 3 respectively, and the two No. 2 gears 35 are engaged with each other. A rubber ring 36 is sleeved on the outer wall of each flattening roller 3, and two groups of threaded grooves 37 with opposite rotation directions are opened on the outer wall of the rubber ring 36.

[0092] One end of one of the flattening rollers 3 is connected to one of the pressing rollers 2 through a synchronous belt (not shown in the figure). When the pressing roller 2 rotates, one of the flattening rollers 3 rotates synchronously. Then, through the transmission of the two second gears 35, the two flattening rollers 3 will eventually rotate in opposite directions. After each flattening roller 3 rotates, the rubber ring 36 on it will also rotate, thereby flattening the carpet from the middle to the two sides through two sets of thread grooves 37 rotating in opposite directions.

[0093] Working principle:

[0094] During the process of correcting the deviation of the two carpets and then pressing them together, the carpet at the bottom passes horizontally directly through the two pressing rollers 2, while the carpet at the top first passes over the deflection-correcting roller 1 and then passes between the two pressing rollers 2. When installed, the deflection-correcting roller 1 needs to be higher than the pressing roller 2 at the top, so that there is a height difference between the deflection-correcting roller 1 and the pressing roller 2. This height difference creates an opening between the two carpets, through which the glue sprayer sprays glue into the space between the two carpets.

[0095] The upper carpet will be corrected by the correction roller 1 when passing through it, so that the upper and lower carpets are completely overlapped before pressing, preventing the two carpets from being misaligned and causing the quality of the pressed product to be substandard.

[0096] Before the two carpets pass through the pressing mechanism, the glue sprayer sprays glue between the two carpets, and then the two carpets are pressed up and down by the rotation of the two pressing rollers 2;

[0097] After the two carpets are pressed together, they pass through the flattening mechanism. At this time, the two flattening rollers 3 will flatten the upper and lower surfaces of the carpet from the middle to the sides to ensure that the carpet surface is flat;

[0098] When the carpet is flattened, the unsolidified glue will be squeezed to the sides of the carpet, causing the glue to flow on the sides of the carpet. The glue solidified on the sides of the carpet will affect the subsequent edge sealing process. As the carpet is rolled up, the glue flowing on the sides of the carpet will continue to drip onto the floor. When the glue solidifies, glue marks will be left on the floor that are difficult to remove. Therefore, the two sets of side glue removal components of this device are used to remove glue from the two sides of the carpet in real time.

[0099] First, the oblique scraper 4 is used to scrape off the glue hanging on the side of the carpet in real time, and then the reciprocating scraping mechanism of the device is used to scrape off the glue accumulated on the oblique scraper 4. During this process, the driving member drives the composite scraper to rise and fall back. Before the composite scraper falls, the movable scraper 8 is extended through the telescopic mechanism and scrapes the glue on the oblique scraper 4 downward into the collecting bucket 5 when it falls. When the composite scraper rises, the long scraper 6 will scrape off the glue on the oblique scraper 4 and pass through the long scraper 6. The scraped glue liquid is led into the collecting bucket 5. Before the composite scraper rises, the movable scraper 8 is in a retracted state through the telescopic mechanism. Then, during the retraction of the movable scraper 8, the short scraper 7 will scrape the glue liquid on the movable scraper 8, and the scraped glue liquid is led into the collecting bucket 5 through the short scraper 7. In summary, the oblique scraper 4 can realize real-time scraping of the glue liquid hanging on the side of the carpet while preventing the glue liquid from accumulating on the oblique scraper 4 and the movable scraper 8 and affecting the scraping effect of the two.
