Description

Technical Field

[0001] The invention relates to the technical field of cord dip processing, in particular to a device for scraping off colloid in the excess path after the cord dip processing. Background Art

[0002] Cord is the warp material of woven cord fabric, referred to as cord, which can be used as rubber products such as tires, conveyor belts, transmission belts, etc. It is usually divided into four categories: viscose cord, polyamide cord, polyester cord and aromatic polyamide cord. Their performance varies and is often selected based on the performance requirements of rubber products and factors such as cost.

[0003] According to the patent document with publication number CN118345575A, "through the swinging action of the swing frame, the brush plate swings with the swing frame and performs a swinging glue brushing action on the cord line. At the same time, the rotating wheel rotates through the connecting rod transmission, so that the reciprocating slider drives the brush plate to perform linear reciprocating sliding, further promoting the uniformization of the glue attached to the cord line, and also avoiding excessive glue on the cord line, which greatly improves the gluing effect of the cord line."

[0004] However, considering that the brush plate is adhered to the glue after working for a long time, the glue uniformity effect achieved on the surface of the cord is reduced as it slides and brushes the glue, which may easily cause the problem of glue blocks on the surface of the cord that is subsequently dried;

[0005] At the same time, when scraping glue on the surface of the cord, the dryness of the glue on the surface of the cord is not taken into consideration. The direct and irregular continuous scraper contact can easily cause uneven distribution of the glue on the surface of the cord, and in severe cases, cause damage to the surface of the cord.

[0006] Therefore, we propose a device for scraping off the excessive colloid after the cord is dipped in the rubber. Summary of the invention

[0007] The object of the present invention is to provide a device for scraping off the colloid in the path of a cord after the rubber dipping process, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: a device for scraping off the colloid in the diameter of a cord after dipping, comprising a dipping box, a scraping cover is fixed to one side of the dipping box by bolts, and a collecting dish is fixed to the bottom of the scraping cover and located on the dipping box by bolts;

[0009] A scraper mechanism is installed on the inner walls of both sides of the scraper cover, and the scraper mechanism includes a rotating shaft, a rotating disk and a rotating block. The inner walls of both sides of the scraper cover are movably connected with the rotating shaft through bearings, and a rotating disk is evenly sleeved and fixed on the rotating shaft. The outer wall of the rotating disk is evenly and symmetrically connected to the rotating block on the center line. A friction block is fixed to one side of the rotating block by bolts, and a spring is installed between two adjacent rotating blocks.

[0010] Furthermore, a motor is fixed to the outer wall of the scraper cover by bolts, the output end of the motor is fixed to one end of the rotating shaft, the inner walls on both sides of the scraper cover and the top of the turntable are fixedly connected with a transmission mechanism, and a special-shaped disk group is evenly and movably connected to the bottom of the transmission mechanism, and the special-shaped disk group is respectively abutted against the outer wall of the turntable side rotating block.

[0011] Furthermore, a filter cover is fixed to one side of the glue dipping box by bolts, a liquid guide tube is installed on one side of the filter cover, through holes are evenly opened on one side of the glue dipping box, and the through hole side is connected to the filter cover.

[0012] Furthermore, the bottom of the collecting dish is connected to a fluid guide mechanism, the upper connecting pipe of the fluid guide mechanism is connected to one side of the filter cover, and a filter plate is installed on the inner wall of the filter cover and at one end of the upper connecting pipe of the fluid guide mechanism.

[0013] Furthermore, guide rollers are movably connected to the inner walls of both sides of the dipping box via bearings, and movable pressing rollers are symmetrically mounted on the dipping box via bolts.

[0014] Furthermore, a top cover is fixed to the inner walls on both sides of the dipping box by bolts, a drying mechanism is fixed to the top inner wall of the top cover by bolts, an identification cover is installed inside the top cover and on the side of the drying mechanism, and a heating mechanism is fixed to the top of the top cover by bolts.

[0015] Furthermore, an electric control box is fixed to one side of the dipping box by bolts, and the identification cover is used for collecting and sending comprehensive information of cord dipping, wherein the comprehensive information of cord dipping includes a cord dipping moisture factor, a cord dipping gloss factor and a cord dipping image;

[0016] The electric control box includes a cord dip signal decision module and a controller. The cord dip signal decision module is used to obtain and process the cord dip comprehensive information. The specific processing steps are as follows:

[0017] S1: The cord glue dipping humidity factor and the cord glue dipping gloss factor obtained by the identification hood are marked as Ls and Lg;

[0018] S2: The cord glue dipping drying coefficient Y is obtained according to the formula, and the obtained cord glue dipping drying coefficient Y is compared with the cord glue dipping drying coefficient threshold y stored in the cord glue dipping signal decision module; when Y≥y, a drying adjustment signal is generated and sent to the controller; when Y<y, a cord glue dipping surface image signal is generated and sent to the identification cover to start the backlight, trigger the top camera to take pictures, and obtain the images of both sides of the cord glue dipping in real time during the movement process, and send the real-time collected images of both sides of the cord glue dipping to the image processing module in the external computer for cord surface contour comparison, and then the scraping signal generated by the computer processing is sent to the controller;

[0019] The controller actively adjusts the temperature value on the heating mechanism when receiving the drying adjustment signal, and controls the activity of the power unit in the transmission mechanism when obtaining the scraping signal, driving the special-shaped disc group to rotate. The special-shaped disc group rotates and squeezes the rotating block, causing the friction block on the rotating block to clamp the surface of the cord, thereby completing the scraping of excess colloid on the surface of the cord.

[0020] The method for scraping off the excess colloid after the cord is dipped in the glue is as follows: the cord is passed through the guide roller, the movable pressure roller and the surface of the turntable in sequence, and after the cord is tightened, the position of the movable pressure roller on the top of the dipping box is adjusted to press the cord surface to the bottom of the dipping liquid surface, and then the glue is filled into the filter cover through the liquid guide pipe, and the glue gradually flows over the cord at the bottom of the movable roller along the through hole on the surface of the dipping box;

[0021] As the cord is wound, the drying mechanism installed in the top cover starts to work, guides the hot air flow generated by the heating mechanism, and performs the cord dipping and drying operation. At the same time, the sensor in the entire identification cover identifies the dryness of the cord surface and sends the relevant monitoring signal to the electronic control box. After processing, the relevant control signal is obtained to adjust the temperature of the exhaust gas from the heating mechanism until the discharged cord shows that the dryness meets the standard. Subsequently, the roughness of the cord surface is detected, and the cord areas that do not meet the standard are marked. After the corresponding cord moves to the turntable, the transmission mechanism drives the corresponding special-shaped disc group to rotate, squeezes the rotating block on the turntable and pushes the friction block to contact the corresponding cord position, completing the colloid scraping operation on the cord surface.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the surface drying of the cord after dipping is analyzed, and the colloid information on the surface of the cord is collected through the electric control box for decision-making processing, the drying mechanism is actively controlled to adjust the temperature, and the surface image acquisition operation of the cord is triggered at the same time. The colloid adhesion conditions on the surface of the cord on multiple lines are obtained through analysis and intelligent identification, and the abnormal distribution area of ​​the colloid on the surface of the cord is marked. The power element in the transmission mechanism is controlled by the electric control box to work, and the corresponding special-shaped disc group on the turntable side is driven to work. The special-shaped disc group rotates and squeezes the rotating block, so that the friction block on the side of the rotating block contacts the abnormal distribution area of ​​the colloid on the surface of the cord, and the colloid treatment on the surface of the cord is completed, and a more uniformly coated cord is obtained. At the same time, the friction block only performs glue scraping treatment on the cord in the abnormal glue coating area, which avoids the influence of the scraping component on the regular surface area of ​​the cord and itself due to the accumulation of residual materials for a long time;

[0024] 2. In the present invention, according to the different diameters of the cords, the motor on the scraper cover rotates, driving the turntable on the entire shaft to rotate at a fixed angle, so that the friction blocks of corresponding sizes are moved to both sides of the cords, and the rotating blocks are squeezed to fully wrap the cords after gluing, thereby realizing the gluing operation of cords with different diameters, and the equipment operation is flexible;

[0025] 3. In the present invention, the excess colloid on the surface of the cord is scraped off, and a special collection dish is set to collect the colloid, and the fluid guide mechanism is used to recover the residual material. After the filter plate is filtered and cleaned in the filter cover, the colloid flows into the dipping box for reuse, thereby avoiding the waste of the cord coating colloid.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-6 , the present invention provides a technical solution:

[0035] Embodiment 1: The scraping operation of the colloid in the path after the cord is dipped in the glue is performed to avoid the problem of colloid agglomeration on the surface of the cord after the dip is dried. For the scraping operation of the entire cord, the drying degree of the colloid on the surface of the cord after the dip is completed needs to be considered. The colloid on the outer surface of the cord dries faster. If the colloid is not completely dried on the surface of the cord during the scraping, it is easy to cause the problem of colloid striping on the cord rubber surface, which seriously affects the subsequent use.

[0036] Therefore, when scraping the colloid on the surface of the cord, the colloid on the surface of the cord after dipping and drying is first detected online. Figure 1 and Figure 6 As shown, an identification cover 19 is installed on the inner wall of the top cover 6. The entire identification cover 19 is used for collecting and sending comprehensive information of the cord dipping, wherein the comprehensive information of the cord dipping includes the cord dipping humidity factor, the cord dipping gloss factor and the cord dipping image. Through online combined analysis of the colloid on the surface of the cord, the humidity sensor and the glossiness detector installed on the side of the identification cover 19 are used to obtain the colloid data on the surface of the cord, and send it to the cord dipping signal decision module in the electric control box 3;

[0037] The cord dip signal decision module is used to obtain and process the cord dip comprehensive information. The specific processing steps are as follows:

[0038] S1: Mark the cord glue dipping humidity factor and the cord glue dipping gloss factor obtained by the identification cover 19 as Ls and Lg;

[0039] S2: According to the formula The cord glue dipping drying coefficient Y is obtained by processing, wherein a1 and a2 are correction factors, and a2>a1>0, and the obtained cord glue dipping drying coefficient Y is compared with the cord glue dipping drying coefficient threshold y stored in the cord glue dipping signal decision module;

[0040] When Y≥y, a drying adjustment signal is generated and sent to the controller;

[0041] When Y<y, an image signal of the cord glue dipping surface is generated and sent to the identification cover 19 to start the backlight, triggering the side camera of the identification cover 19 to take a photo, and obtaining the images of both sides of the cord glue dipping in real time during the movement, and sending the real-time collected images of both sides of the cord glue dipping to the image processing module in the external computer for the comparison of the surface contour of the cord. For the real-time images of both sides of the cord glue dipping obtained in the external computer, a cord surface abnormality model is first established, and the cord glue dipping images are manually marked for abnormalities, such as glue marks and bubbles on the surface of the cord, and then the accumulated marked images are uniformly subjected to AI deep recognition learning, and the subsequent production images are automatically marked, and the scraping signals are automatically generated, and then the scraping signals generated by computer processing are sent to the controller;

[0042] The controller obtains the scraping signal to scrape the glue off the cord on the corresponding line, and then scrapes the glue after precise positioning. Compared with the continuous contact scraping operation, it is easy to cause damage to the cord.

[0043] The drying adjustment signal obtained by the controller indicates that the cord surface is poorly dry at this time, and only the drying mechanism 18 in the top cover 6 needs to be adjusted. The drying mechanism 18 is connected to the heating mechanism 7. The temperature of the hot air generated by the heating mechanism 7 increases, which accelerates the drying of the cord surface during the moving process.

[0044] For the cord rubber scraping operation, such as Figure 4 and Figure 5 As shown, a scraping mechanism 15 is installed at the end of the cord outlet, wherein a cord conducting turntable 152 adapted to the guide roller 4 and the movable pressure roller 5 is evenly installed on the rotating shaft 151, and a rotating block 153 is evenly rotated and connected to the outer wall of the turntable 152, and a friction block 154 is fixedly installed on one side of the rotating block 153, and a spring 155 is installed between two adjacent rotating blocks 153, and the corresponding friction block 154 is selected according to the cord wire diameter constraint;

[0045] Considering that the rubber scraping operation of the cord needs to be performed according to the required size, four groups of rotating blocks 153 are installed on a single turntable 152, and the diameters of the holes formed by the friction blocks 154 on each group of rotating blocks 153 are different, which is suitable for rubber scraping operations on cords of different sizes. Therefore, the motor 14 installed on the side of the scraper cover 8 drives the rotating shaft 151 to rotate at a fixed angle, and the rotating block 153 that meets the size is rotated to the top to start the selective rubber scraping operation;

[0046] When the cord moves along the turntable 152, according to the length of the scraping signal sent by the controller, the transmission mechanism 16 located at the top of the turntable 152 in the scraper cover 8 starts to work, driving the special-shaped disc group 17 on the corresponding line to rotate, such as Figure 5 As shown, when the two disk blocks of the special-shaped disk group 17 rotate relative to each other, they gradually contact the rotating block 153 and drive the friction block 154 to contact the surface of the cord, thereby completing the removal of excess colloid on the surface of the cord. The contact time of the friction block 154 and the cord corresponds to the scraping signal, thus achieving directional scraping of excess colloid on the surface of the cord. Compared with the continuous contact and scraping operation of the cord, it is easy to cause accumulation of residual material on the scraper side, which seriously affects the normal winding of the cord.

[0047] Embodiment 2: Considering the residual glue left over from the rubber scraping treatment on the surface of the cord, Figure 1 As shown, a collecting dish 9 is fixedly installed at the bottom of the scraper cover 8 to avoid waste of residual glue. The residual glue after secondary melting finally goes into the filter cover 2 on the side of the dipping box 1 along the fluid guide mechanism 10;

[0048] However, considering that some cord surface lines are left in the residual glue, a filter plate 13 is installed in the entire filter cover 2 to intercept impurities in the flowing colloid. The entire filter cover 2 exchanges colloid through the through hole 12 opened on the outer wall of the dipping box 1, and a liquid guide pipe 11 is also installed on the other side of the filter cover 2. When the cord surface is dipping in glue, the colloid is continuously discharged into the filter cover 2 through the liquid guide pipe 11, and finally the liquid level in the dipping box 1 rises to a specified height, so that the cord is immersed in the colloid. When the cord is dipped in glue, the colloid in the dipping box 1 can be recovered through the fluid guiding mechanism 10.

[0049] The working principle of the present invention is as follows: the cord is passed through the guide roller 4, the movable pressure roller 5 and the surface of the turntable 152 in sequence, and after the cord is tightened, the position of the movable pressure roller 5 on the top of the dipping box 1 is adjusted to press the cord surface to the bottom of the dipping liquid surface, and then glue is filled into the filter cover 2 through the liquid guide pipe 11, and the glue gradually flows over the cord at the bottom of the movable roller along the through hole 12 on the surface of the dipping box 1;

[0050] As the cord is wound, the drying mechanism 18 installed in the top cover 6 starts to work, guides the hot air flow generated by the heating mechanism 7, and performs the cord dipping and drying operation. At the same time, the sensor in the entire identification cover 19 identifies the dryness of the cord surface and sends the relevant monitoring signal to the electric control box 3. After processing, the relevant control signal is obtained to adjust the temperature of the exhaust gas from the heating mechanism 7 until the discharged cord shows that the dryness meets the standard. Subsequently, the roughness of the cord surface is detected, and the cord area that does not meet the standard is marked. After the corresponding cord moves to the turntable 152, the transmission mechanism 16 drives the corresponding special-shaped disk group 17 to rotate, squeezes the rotating block 153 on the turntable 152 and pushes the friction block 154 to contact the corresponding cord position, completing the scraping of the colloid on the cord surface.

[0051] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
