[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] On the continuous production line of carpets, it is often difficult to accurately control the distribution range of glue after coating, and glue overflow or flow is very likely to occur. These excess glues may not only directly adhere to the conveyor belt, forming stains that are difficult to remove, but long-term accumulation will seriously affect the surface flatness of the conveyor belt, increase running resistance, and even cause the conveyor belt to slip or wear, affecting production efficiency and equipment life. Although scrapers are widely designed in the prior art to scrape off foreign particles on the surface of the conveyor belt, they are often not designed for sticky materials, and therefore cannot effectively scrape off sticky glue.

[0083] Unless otherwise stated, the term "plurality" means two or more.

[0084] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0085] Combination Figure 1-4 As shown, the embodiment of the present disclosure provides a conveyor belt scraping and cleaning device for carpet production equipment, including: a frame 14, a protective plate 8, a coating roller 11, a brush roller 12, and a scraping plate 13;

[0086] The frame 14 is arranged around a part of the return section 1 of the conveyor belt; the frame 14 can be welded with high-strength steel to ensure the stability and durability of the overall structure. The frame 14 is an open frame surrounding a part of the return section 1 of the conveyor belt to facilitate the installation and maintenance of various cleaning components, and a fixed foot is provided at the bottom of the frame 14.

[0087] The protective plates 8 are arranged on both sides of the conveyor belt and connected to the frame 14. In order to prevent the splashing of the degumming agent or dirt during the cleaning process from polluting the surrounding environment, the present invention arranges the protective plates 8 on both sides of the conveyor belt. The protective plates 8 are made of corrosion-resistant and easy-to-clean stainless steel material and are tightly connected to the frame 14 by bolts or slots. The height of the protective plates 8 is slightly higher than the return section 1 of the conveyor belt, forming an effective barrier to ensure the safety and environmental protection of the cleaning operation. The protective plates 8 are provided with a number of holes for installing various cleaning components.

[0088] The coating roller 11 is arranged on the frame 14, and applies the degumming agent to the surface of the return section 1 of the conveyor belt; the surface of the coating roller 11 is covered with a soft and absorbent sponge or fiber material for evenly applying the degumming agent. The degumming agent is delivered to the coating roller 11 through a special supply system (such as a pumping device), and is evenly applied to the surface of the conveyor belt when the roller rotates. The rotation speed and position of the coating roller 11 can be adjusted according to the speed and width of the conveyor belt to ensure effective coverage of the degumming agent. In this embodiment, the coating roller 11 is tightly pressed against the return section 1 of the conveyor belt and is driven by the conveyor belt. When the conveyor belt moves, it drives the coating roller 11 to rotate synchronously.

[0089] The brush roller 12 is arranged on the frame 14, on one side of the coating roller 11 and behind the coating roller 11, and brushes the surface of the return section 1 of the conveyor belt; the bristles are made of highly elastic, wear-resistant and non-shedding materials, such as nylon or polyester fibers. The rotation direction of the brush roller 12 is opposite to the movement direction of the conveyor belt. Through the friction of the bristles, the glue remover is fully mixed with the glue residue on the surface of the conveyor belt, and the dissolving function of the glue remover is brought into play. The choice of the glue remover is determined by the type of glue used for the carpet, and the rotation speed and bristle hardness of the brush roller 12 can be adjusted according to actual cleaning needs.

[0090] The scraper plate 13 is arranged on the protective plate 8, on one side of the brush roller 12 and behind the brush roller 12, to scrape off the dirt on the surface of the return section 1 of the conveyor belt. The scraper plate 13 is made of wear-resistant materials such as metal or polyurethane to ensure stability and durability for long-term use. The edge of the scraper plate 13 forms a sharp edge, which can be close to the surface of the conveyor belt to completely scrape off the residual dirt after coating and brushing, including residual degumming agent. If it is necessary to completely wipe off the dirt on the surface of the conveyor belt, a scrubbing roller can be set behind the scraper plate 13. In the embodiment of the present application, a little residual degumming agent during the carpet production process will not affect the production, so it can be omitted.

[0091] A carpet production equipment conveyor belt scraping and cleaning device provided by an embodiment of the present disclosure is used. First, the coating roller 11 evenly coats the degumming agent on the surface of the conveyor belt return section 1. Then, the brush roller 12 loosens the glue residue and mixes it with the degumming agent through the rotating brushing action. Finally, the scraping plate 13 finely scrapes off the remaining dirt and degumming agent, and the residual glue will not stick to the scraping plate 13 and the brush roller 12, thereby achieving thorough cleaning of the conveyor belt. The entire cleaning process is continuous and efficient, and will not cause damage to the conveyor belt and the equipment.

[0092] In some embodiments, the carpet production equipment conveyor belt scraping and cleaning device further includes: a liquid storage tank 6, a main pipeline 116, a plurality of fan-shaped nozzles 115, a pump body 10, a water receiving tank 117, and a return pipe;

[0093] The liquid storage tank 6 stores the degumming agent; the position of the liquid storage tank 6 can be set according to actual needs, and the present invention does not limit this. It can be placed on the outside of the protective plate 8, or on the inside of the protective plate 8 as needed, below the water tank 117. The shape of the liquid storage tank 6 can be set according to actual needs, and the present invention does not limit this.

[0094] The main pipeline 116 is disposed below the coating roller 11; it can also be disposed on the side of the coating roller 11 according to actual needs, and the present invention does not limit this.

[0095] A plurality of fan-shaped nozzles 115 are evenly arranged on the main pipeline 116, and the nozzles are facing the coating roller 11; the nozzles can also be set to nozzles of other shapes according to actual needs. The fan-shaped nozzles 115 used in this embodiment correspond to the shape of the roller, and a small number of nozzles are used to achieve large-scale linear spraying, covering the entire surface of the coating roller 11, which is more efficient. The present invention does not limit the specifications of the nozzles.

[0096] The pump body extracts the degumming agent in the liquid storage tank 6 and transports it to the main pipeline 116; the pump body is made of a high-performance, corrosion-resistant centrifugal pump or diaphragm pump, which can stably and efficiently extract the degumming agent in the liquid storage tank 6 and transport it to the main pipeline 116.

[0097] The water receiving tank 117 is disposed below the main pipeline 116 ; the water receiving tank 117 is disposed below the main pipeline 116 and is used to collect the excess debonding agent sprayed from the fan-shaped nozzle 115 and the liquid dripping from the coating roller 11 .

[0098] The reflux pipe connects the water receiving tank 117 and the liquid storage tank 6. The reflux pipe returns the degumming agent in the water receiving tank 117 to the liquid storage tank 6, so as to realize the recycling of the degumming agent.

[0099] When glue residue appears on the conveyor belt surface, the cleaning device is started. The pump body starts to work, extracts the glue remover from the liquid storage tank 6 and transports it to the fan-shaped nozzle 115 through the main pipeline 116. The fan-shaped nozzle 115 sprays the glue remover in the form of mist evenly on the surface of the coating roller 11, and the excess glue remover and dissolved glue drip into the water receiving tank 117, and after being filtered, it returns to the liquid storage tank 6 through the reflux pipe for recycling.

[0100] In some embodiments, the degumming agent in the liquid storage tank 6 can also be pumped into the water receiving tank 117 by a pump body, and then a portion of the coating roller 11 is immersed below the degumming agent liquid level in the water receiving tank 117 to achieve coating the degumming agent on the coating roller 11.

[0101] In some embodiments, the coating roller 11 includes: a water absorbing layer 111, a mounting cylinder 112, a first rotating shaft 114, a fixed shaft 42, and a wiper 113;

[0102] The water-absorbing layer 111 can absorb and temporarily store part of the degumming agent; this layer is designed with a porous structure, which can quickly absorb and temporarily store a certain amount of degumming agent to ensure continuous and stable release during the coating process.

[0103] The installation tube 112 is installed and fixed on the inner side of the water absorbing layer 111; the installation tube 112 provides a stable support structure for the water absorbing layer 111, and fixes the water absorbing layer 111 thereon by adhesive or mechanical fastening to prevent displacement or falling off during use.

[0104] The first rotating shaft 114 is fixedly mounted inside the mounting tube 112, and both ends are rotatably connected to the frame 14;

[0105] A fixed shaft 42, arranged on the protective plate 8;

[0106] The wiper 113 is arranged on the fixed shaft 42, with one end abutting against the surface of the water-absorbing layer 111 to scrape off the excess degumming agent on the surface of the water-absorbing layer 111. The fixed shaft 42 is arranged parallel to one side of the coating roller 11, or below the side, and is fixedly connected to the protective plate 8 by bolts or other fasteners. The wiper 113 is installed on the fixed shaft 42, with one end abutting against the surface of the water-absorbing layer 111 to form a certain scraping angle. The material of the wiper 113 is selected from materials with moderate hardness and good wear resistance, such as hard rubber or special plastics, to ensure that the excess degumming agent on the surface of the water-absorbing layer 111 can be effectively scraped off, the degumming agent can be saved, and waste can be avoided, and the water-absorbing layer 111 will not be damaged. The water hanging plate is arc-shaped, and the inner concave surface 133 faces the direction below the fixed shaft 42.

[0107] In some embodiments, Figure 5 The fixed shaft 42 is connected to the protective plate 8 through the first adjusting device 4, and the first adjusting device 4 includes: a fixed rod, an adjusting plate, an adjusting hole, and a screw 43;

[0108] A first fixing rod 44, fixedly connected to the protection plate 8;

[0109] A first adjustment plate 41 is fixedly connected to a fixed shaft 42;

[0110] An adjustment hole is provided on the adjustment plate;

[0111] The screw rod 43 has one end passing through the adjustment hole and fixedly connected to the fixing rod, and the other end is sequentially sleeved with a first washer, a spring, a second washer, and a nut;

[0112] The position of the adjusting nut can adjust the pressure applied by the spring to the adjusting plate, thereby adjusting the scraping effect of the water-hanging plate on the debonding agent on the surface of the water-absorbing layer 111 .

[0113] In actual use, the user can adjust the compression of the spring by rotating the adjustment nut according to the adhesion of the degumming agent on the surface of the water-absorbing layer 111. When it is necessary to enhance the scraping effect, the compression of the spring can be appropriately increased to increase the pressure of the adjustment plate on the water-absorbing layer 111; conversely, when it is necessary to reduce the scraping force, the compression of the spring is reduced. This flexible adjustment method saves the amount of degumming agent used, ensures that the cleaning device can adapt to different working environments and cleaning needs, and improves work efficiency and cleaning quality.

[0114] In some embodiments, the carpet production equipment conveyor belt scraping and cleaning device further includes: a positioning plate 2, a slide groove 3, a slider 35, an adjustment stud 32, and a locking nut 33;

[0115] Since the coating roller 11, the brush roller 12, and the scraper plate 13 all exert an upward force on the conveyor belt, if the conveyor belt is not positioned downward, it will not be able to complete the cleaning better. The downward positioning can be performed using a roller or a baffle, and the present application does not limit this. This embodiment discloses a positioning plate 2 to play a downward positioning role, such as Figure 6 The positioning plate 2 includes: a straight section 21 and a bent section 22. The straight section 21 is arranged on the upper part of the contact portion between the return section 1 of the conveyor belt and one or more of the coating roller 11, the brush roller 12, and the scraping plate 13. Two bent sections 22 are provided and are respectively connected to the two ends of the straight section 21. The bent sections 22 are bent in the direction away from the return section 1 of the conveyor belt. The straight section 21 plays a role in positioning the conveyor belt, and the bent section 22 is used to protect the conveyor belt and enhance the overall stability of the positioning plate 2.

[0116] like Figure 7 , the slide 3 is fixedly arranged on the protective plate 8;

[0117] A slider 35, a part of which is slidably disposed in the slide groove 3, and a part of which is connected to the positioning plate 2;

[0118] The adjusting stud 32 is threadedly matched with the slider 35, one end of which is rotatably connected to the bottom of the slide slot 3, and the other end passes through the slide slot 3 and is provided with an adjusting slot 34 at the end; the adjusting slot 34 is a hexagonal slot and is used in conjunction with a hexagonal wrench.

[0119] The locking nut 33 is arranged on the adjusting stud 32 outside the slide slot 3 .

[0120] The user can move the slider 35 by rotating the adjustment slot 34 of the adjustment stud 32 according to the position requirements of the conveyor belt or cleaning component, thereby driving the positioning plate 2 to move to the desired position along the slide slot 3. After the adjustment is completed, the locking nut 33 is tightened to fix the position of the slider 35 to ensure the stability and reliability of the cleaning device during operation.

[0121] In some embodiments, the brush roller 12 includes: a second rotating shaft, a brush cylinder 122;

[0122] The second rotating shaft is rotatably arranged on the frame 14, and one end is connected to the rotating driving mechanism 5; the rotating driving mechanism 5 is the power source for driving the brush roller 12 to rotate. In this embodiment, the rotating driving mechanism 5 is connected to the other end of the second rotating shaft through a coupling to transmit the rotating power of the motor to the second rotating shaft. The rotating driving mechanism 5 includes a motor and a reducer, and a suitable motor model and reduction ratio can be selected according to the actual working conditions to ensure that the brush roller 12 runs at a suitable speed to achieve the best cleaning effect. The rotating driving mechanism 5 is fixedly arranged on the frame 14.

[0123] The brush barrel 122 is arranged on the second rotating shaft. The outside of the brush barrel 122 is covered with dense bristles. These bristles are usually made of soft and wear-resistant materials, such as nylon, polyester fiber, etc., to ensure that the conveyor belt surface will not be damaged while effectively cleaning. The brush barrel 122 is firmly set on the second rotating shaft by fasteners (such as bolts, buckles, etc.) to ensure that it will not fall off or loosen during rotation. The diameter, length, density and hardness of the brush barrel 122 and other parameters can be adjusted according to specific cleaning needs.

[0124] like Figure 8 , 9, In ​​some embodiments, the scraper plate 13 further includes: a plate body, an inner groove 134, a guide protrusion 135, an embedded body 138, a third rotating shaft 151, and a connecting frame 137;

[0125] The plate body is in the shape of a crescent, and includes: an inner concave surface 133, an assembly surface, a convex surface 132, and a friction surface 131. The inner concave surface 133 faces the direction of the conveyor belt when it returns or the direction slightly below the conveyor belt when it returns, and the convex surface 132 faces the direction of the conveyor belt when it returns. The friction surface 131 is located at the far end of the plate body and is in contact with the surface of the return section of the transmission belt; the crescent shape enables the scraping plate 13 to better fit the curvature of the conveyor belt and improve the scraping efficiency. The inner concave surface 133 faces the direction of the conveyor belt when it returns, and is used to guide and initially contact the residue on the conveyor belt; the convex surface 132 faces the direction of the conveyor belt when it returns, and improves the thickness and wear resistance of the plate body; the friction surface 131 is located at the far end of the plate body, and is closely in contact with the surface of the return section 1 of the conveyor belt, and the blade formed in cooperation with the inner concave surface 133 performs the actual scraping action.

[0126] The inner groove 134 is provided on the inner concave surface 133; the function of the inner groove 134 is that the dirt sliding down from the upper part of the inner concave surface 133 will adhere to the inner concave surface 133 and slide downward. When the dirt slides down to the inner groove 134, since the groove wall is concave toward the inner side of the inner concave surface 133, and the concave angle is greater than 90°, the general attached dirt will not continue to move toward the inner groove 134, but will gather briefly at the inner groove 134 and then fall downward under the action of gravity. Due to the orientation design of the inner groove 134, the falling dirt will not fall onto the inner concave surface 133.

[0127] The guide protrusion 135 is arranged on the inner concave surface 133 and below the inner groove 134. Since the size of the plate body is not large, the width of the inner groove 134 may not be able to prevent large attachments from attaching to the inner concave surface 133. The guide protrusion 135 is a raised structure designed on the inner concave surface 133, and its raised direction can guide the moving direction of the attachment. The extension direction of the protrusion of the present application is close to perpendicular to the direction of the inner concave surface 133, so it can play a good guiding role and prevent dirt from attaching.

[0128] The embedded body 138 is arranged on the assembly surface; the embedded body 138 is made of a material with higher strength, and includes a plurality of embedded claws 139 and a T-shaped slide groove 3. The T-shaped slide groove 3 cooperates with the connecting frame 137 and is connected by bolts. The embedded claws 139 are embedded in the plate body to realize the connection between the plate body and the embedded body 138. The embedded body 138 can be made of metal material, and the plate body is made of polyurethane material.

[0129] The third rotating shaft 151 is arranged on the protective plate 8;

[0130] The connecting frame 137 is partially connected to the embedded body 138, and partially connected to the third rotating shaft 151. The connecting frame 137 and the third rotating shaft 151 can also be connected through a square tube 136. One part of the connecting frame 137 is a slide bar connected to the slide groove 3 of the embedded body 138, and another part is a groove body for accommodating the square tube 136, and is connected to the square tube 136 by bolts. Both ends of the square tube 136 are connected to the third rotating shaft 151. The design of the connecting frame 137 and the embedded body 138 facilitates the rapid replacement of the plate body.

[0131] In some embodiments, the third rotating shaft 151 passes through the protective plate 8 and is rotatably connected to the protective plate 8. A sleeve 152 is sleeved on the portion where the third rotating shaft 151 passes through. A locking screw 153 is provided on the sleeve 152. The locking screw 153 locks the sleeve 152 and the third rotating shaft 151. The sleeve 152 is connected to the protective plate 8 through a second adjusting device, such as Fig.10 The second adjustment device includes: a second fixing rod 155, a second adjustment plate 154, an adjustment hole, and a second screw 43; by adjusting the locking screw 153, the sleeve 152 and the third rotating shaft 151 are movably locked. When the plate body is worn, the friction surface 131 cannot fit tightly on the conveyor belt, and the dirt cannot be scraped cleanly. At this time, the locking screw 153 can be loosened, the angle of the third rotating shaft 151 can be adjusted and then locked again to achieve rapid adjustment of the scraping plate 13.

[0132] A second fixing rod 155, fixedly connected to the protection plate 8;

[0133] The second adjustment plate 154 is fixedly connected to the shaft sleeve 152;

[0134] An adjustment hole is provided on the adjustment plate;

[0135] A second screw rod 43, one end of which passes through the adjustment hole and is fixedly connected to the fixing rod, and the other end of which passes through the gasket and the spring and is connected to the nut;

[0136] The position of the adjusting nut can adjust the pressure applied by the spring to the second adjusting plate 154 , thereby adjusting the contact pressure between the friction surface 131 and the return section 1 of the conveyor belt.

[0137] In some embodiments, the adjustment hole is an oblong hole.

[0138] In some embodiments, the carpet production equipment conveyor belt scraping and cleaning device further includes: a waste collection tank 9, a material blocking plate 121;

[0139] The waste collection tank 9 is arranged below the brush roller 12 and the scraper plate 13 and connected to the protection plate 8;

[0140] In some embodiments, a waste box 7 is further provided. The waste box 7 is arranged outside the protective plate 8. The protective plate 8 is provided with a discharge port connecting the waste box 7 and the waste collecting trough 9.

[0141] The baffle plate 121 is arranged on the side wall of the waste collection tank 9 close to the coating roller 11, with one end close to the return section 1 of the conveyor belt and bent toward the brush roller 12, and the other end close to the bottom of the waste collection tank 9 and bent toward the wall of the waste collection tank 9. The baffle plate 121 solves the problem of waste splashing and overflowing. One end of the baffle plate 121 is close to the return section 1 of the conveyor belt and bent toward the brush roller 12 to form a natural guiding surface. The waste scraped from the conveyor belt can slide smoothly along the guiding surface of the baffle plate 121 into the waste collection tank 9, reducing the splashing and diffusion of the waste.

[0142] The other end of the baffle plate 121 is close to the bottom of the waste collection tank 9 and is bent toward the wall of the waste collection tank 9. This design helps prevent the waste from overflowing from the side of the waste collection tank 9 during the collection process, ensuring the collection effect of the waste. At the same time, this curved design can also slow down the falling speed of the waste to a certain extent, reducing impact and noise.
