Description

Technical Field

[0001] The present application relates to the technical field of glue hanging machines, and in particular to a carpet glue hanging machine. Background Art

[0002] According to the different weaving methods, woven carpets can be divided into tufted carpets, braided carpets, needle-punched carpets, etc. Each type of carpet requires a corresponding carpet adhesive to provide the required performance. Tufted carpets have a very loose structure because the pile yarn is woven into the primary base fabric by a tufting machine, without overlapping warp and weft threads as a constraint. Therefore, carpet adhesive is needed to fix the pile and bond the secondary base fabric.

[0003] Gluing machines are often used to coat tufted carpets with adhesive. At present, the gluing process adopted by most tufted carpet manufacturers in China is as follows: the carpet embryo enters the gluing machine with the back side facing downwards, and the carpet embryo is pressed onto the adhesive roller by the tension roller. The configured carpet adhesive is pumped into the adhesive tank of the gluing machine, and the carpet adhesive is brought up by the rotation of the adhesive roller and the viscosity between the adhesive roller and the latex. The adhesive roller coats the carpet adhesive on the back side of the carpet embryo, and the excess carpet adhesive is scraped off by the scraper installed above the adhesive tank. The carpet embryo after adhesive coating is bonded to the secondary base fabric before drying, compacted by the pressure roller, and then thoroughly dried in an oven.

[0004] However, since the back hair of the carpet blank is uneven, when the glue roller is gluing the carpet blank, it is easy to cause less glue where the back hair gathers and glue to gather where the back hair is sparse, thus wasting a lot of glue. Utility Model Content

[0005] In order to improve the uniformity of applying glue to the back of a carpet embryo, the present application provides a carpet glue hanging machine.

[0006] The present application provides a carpet glue hanging machine, which adopts the following technical solution:

[0007] A carpet glue-applying machine comprises a casing, wherein a feed port and a discharge port are respectively arranged on both sides of the casing, a first traction roller group and a second traction roller group for pulling a carpet embryo are arranged in the casing, a glue tank is also arranged in the casing, a glue coating roller is rotatably arranged in the glue tank, a support frame is arranged in the glue tank, a brush plate is hingedly arranged at one end of the support frame, and the support frame is provided with a swinging component for cooperating to drive the brush plate to fit the back side of the carpet embryo.

[0008] By adopting the above technical scheme, when it is necessary to apply glue to the back of the blanket embryo, first pour the glue liquid into the glue tank, and then start the first traction roller group and the second traction roller group. At this time, the blanket embryo is fed in from the feed port of the casing and sent out from the discharge port of the casing. During the transportation of the blanket embryo, the blanket embryo drives the glue coating roller to rotate, and the glue coating roller then applies the glue liquid in the glue tank to the back of the blanket embryo. Under the cooperation of the swing component, the brush plate scrapes the blanket embryo coated with glue liquid, and the excess glue liquid is collected in the glue coating roller along the brush plate, which is beneficial to improve the uniformity of glue liquid coating.

[0009] Optionally, the swing assembly includes a spring, which is arranged between the support frame and the brush plate, one end of the spring is fixedly connected to the support frame, and the other end of the spring is fixedly connected to the brush plate, and a limiting rod is arranged on the inner wall of the glue tank.

[0010] By adopting the above technical solution, in the natural state of the spring, the spring drives the brush plate to swing towards the direction close to the blanket embryo and presses against the rod wall of the limiting rod. When the blanket embryo is transported in the casing, the blanket embryo squeezes the brush plate, and the brush plate squeezes the spring. At the same time, under the reaction force of the spring, the brush plate presses against the back of the blanket embryo and scrapes the glue liquid, thereby ensuring the uniformity of the glue liquid application.

[0011] Optionally, pressure rollers are symmetrically arranged on both sides above the glue coating roller, and the housing is provided with a lifting mechanism for driving the two pressure rollers to move up and down simultaneously.

[0012] By adopting the above technical solution, in order to adapt to blankets of different thicknesses, the two pressing rollers can be driven by the lifting mechanism to adjust their heights at the same time, which is conducive to ensuring that blankets of different thicknesses are stably attached to the surface of the glue coating roller.

[0013] Optionally, the lifting mechanism includes a fixed drum frame, which is arranged on the inner top wall of the casing, a rod frame is slidably arranged in the fixed drum frame, one end of the rod frame extends outside the bottom of the fixed drum frame, the pressure roller is rotatably arranged in the rod frame, a connecting rod is arranged in the middle of the rod frame, and the casing is provided with a driving assembly for driving the connecting rod to lift and lower.

[0014] By adopting the above technical solution, when the driving assembly drives the connecting rod to rise and fall, the connecting rod simultaneously drives the rod frames on both sides to rise and fall, and the rod frames on both sides respectively drive the pressing rollers to rise and fall, thereby facilitating the simultaneous rise and fall of the pressing rollers on both sides and the stability of pressing the blanket embryo.

[0015] Optionally, the driving assembly includes a screw rod, which is rotatably connected to the top wall of the casing, the bottom end of the screw rod is threadedly connected to the connecting rod, and a hand wheel is coaxially arranged at the top end of the screw rod.

[0016] By adopting the above technical solution, when the hand wheel is turned, the hand wheel drives the screw rod to rotate, and the screw rod drives the connecting rod to rise and fall, and the connecting rod finally drives the pressure roller to rise and fall through the rod frame, which is beneficial to improve the stability of the simultaneous lifting of the pressure rollers on both sides.

[0017] Optionally, a cleaning box is provided in the casing, wiping cottons are symmetrically arranged in the cleaning box, and the casing is provided with a driving member for driving the cleaning box to rise and fall.

[0018] By adopting the above technical scheme, after the blanket embryo is coated with glue, the surface of the first group of traction rollers will be adhered to glue. When it is necessary to clean the glue on the surface of the first group of traction rollers, the cleaning box is first driven up by the driving member. At this time, the first group of traction rollers is inserted into the cleaning box and immersed in the glue cleaning agent. The first group of traction rollers continues to rotate, and under the wiping action of the wiping cotton, the glue adhered to the surface of the first traction roller is cleaned, thereby improving the cleanliness of the surface of the first traction roller.

[0019] Optionally, the driving member is a cylinder, which is arranged on the inner bottom surface of the casing, and the telescopic end of the cylinder is fixedly connected to the bottom surface of the cleaning box.

[0020] By adopting the above technical solution, when the cylinder is started, the telescopic end of the cylinder drives the cleaning box to rise, which is beneficial to improving the stability of the lifting and lowering of the cleaning box.

[0021] Optionally, a clearance hole is provided on the opposite side of the two wiping cottons.

[0022] By adopting the above technical solution, under the action of the give way hole, the first traction roller group is facilitated to be immersed in the cleaning agent, so as to clean the glue adhering to the surface.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] When it is necessary to apply glue to the back of the blanket embryo, first pour glue into the glue tank, and then start the first traction roller group and the second traction roller group. At this time, the blanket embryo is fed in from the feed port of the casing and sent out from the discharge port of the casing. During the conveying process of the blanket embryo, the blanket embryo drives the glue coating roller to rotate, and the glue coating roller then applies the glue in the glue tank to the back of the blanket embryo. Under the cooperation of the swing component, the brush plate scrapes the blanket embryo coated with glue, and the excess glue is collected in the glue coating roller along the brush plate, which is beneficial to improve the uniformity of glue coating.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Example:

[0032] See also Figure 1 and Figure 2 A carpet glue-coating machine includes a housing 1. The housing 1 is used to apply glue to the back of the carpet embryo. The side wall of the housing 1 is hinged with a door 2. The two sides of the housing 1 are symmetrically provided with a feed port 3 and a discharge port 4. The carpet embryo is fed in from the feed port 3 and then discharged from the discharge port 4. A first traction roller group 5 and a second traction roller group 6 are installed in the housing 1. The first traction roller group 5 and the second traction roller group 6 are used to pull the carpet embryo together, and the first traction roller group 5 and the second traction roller group 6 are symmetrically installed in the housing 1. A glue tank 7 is installed on the bottom wall of the housing 1. The glue tank 7 contains glue liquid, and the glue tank 7 is located between the first traction roller group 5 and the second traction roller group 6. A glue coating roller 8 is rotatably connected in the glue tank 7. The top wall of the glue coating roller 8 extends above the glue tank 7, and the glue coating roller 8 is attached to the back of the carpet embryo. A support frame 9 is fixed to the inner wall of the glue tank 7, and a brush plate 10 is hinged at one end of the support frame 9 away from the glue tank 7. The brush plate 10 is used to scrape the back of the blanket embryo so that the glue on the back of the blanket embryo is evenly applied, and the support frame 9 is installed with a swing component for cooperating with the swing of the brush plate 10.

[0033] For details, see Figure 2 and Figure 3 The swing assembly includes a spring 11. The number of springs 11 is multiple, and the multiple springs 11 are respectively installed between the support frame 9 and the brush plate 10. The included angle between the brush plate 10 and the support frame 9 is an acute angle. One end of the multiple springs 11 is respectively fixedly connected to the support frame 9, and the other end of the multiple springs 11 is respectively fixedly connected to the brush plate 10. A limit rod 12 is fixed to the inner wall of the housing 1.

[0034] When the spring 11 is in the natural state, the spring 11 drives the brush plate 10 to press against the rod wall of the limiting rod 12, and at this time, the height of the brush plate 10 is slightly higher than the height when the blanket embryo is transported. When the blanket embryo is transported in the housing 1, the blanket embryo presses the brush plate 10, and the brush plate 10 presses the multiple springs 11. Under the reaction force of the multiple springs 11, the brush plate 10 presses against the back of the blanket embryo, so as to evenly scrape the glue on the back of the blanket embryo.

[0035] See also Figure 2 and Figure 4 In order to facilitate the blanket embryo to fit the roller wall of the glue coating roller 8, pressure rollers 13 are symmetrically installed on both sides of the upper side of the glue coating roller 8, and the housing 1 is installed with a lifting mechanism that drives the two pressure rollers 13 to move up and down at the same time, and the lifting mechanism includes a fixed drum frame 14. The fixed drum frame 14 is fixed to the inner top wall of the housing 1, and a rod frame 15 slides inside the fixed drum frame 14, and the bottom end of the rod frame 15 extends outside the bottom of the fixed drum frame 14. The two pressure rollers 13 are respectively rotatably connected to the rod frame 15, and a connecting rod 16 is fixed in the middle of the rod frame 15.

[0036] See also Figure 2 and Figure 4 In order to facilitate the lifting and lowering of the connecting rod 16, the housing 1 is equipped with a driving assembly, which includes a screw 17, which is rotatably connected to the top wall of the housing 1, the bottom end of the screw 17 is threadedly connected to the connecting rod 16, and the top end of the screw 17 is coaxially fixedly connected with a hand wheel 18.

[0037] Since the blanket blank has different thicknesses, and in order to make the blanket blank fit stably on the roller wall of the glue coating roller 8, and then to coat the glue on the back of the blanket blank, the hand wheel 18 can be rotated at this time, and the hand wheel 18 drives the screw rod 17 to rotate, and under the limiting effect of the fixed cylinder frame 14 on the rod frame 15, the connecting rod 16 drives the rod frame 15 to rise and fall, and the rod frame 15 then drives the two pressure rollers 13 to rise and fall at the same time, so that the blanket blank can be stably fitted on the roller wall of the glue coating roller 8.

[0038] It should be noted that a driving device for driving the screw 17 to rotate can also be coaxially fixed on the top of the housing 1 to improve the convenience of rotating the screw 17.

[0039] For details, see Figure 2 The first traction roller group 5 and the second traction roller group 6 each include a driven roller 19 and a driving roller 20, which rotate in the housing 1 respectively, and the driven roller 19 is located above the driving roller 20, and the driven roller 19 and the driving roller 20 enclose a conveying space for the blanket embryo. The housing 1 is also equipped with a starter for driving the driving roller 20 to rotate, and the starter is a motor 21, and the driving shaft of the motor 21 is coaxially fixedly connected to one end of the driving roller 20.

[0040] It is worth noting that see Figure 2After the blanket with the glue scraped on it passes through the first traction roller group 5, part of the glue will adhere to the driving roller 20 in the first traction roller group 5. If it is not cleaned for a long time, the glue will solidify on the roller wall of the driving roller 20, thereby shortening the spacing of the conveying space, and finally making it difficult for the blanket to pass through the conveying space.

[0041] For this purpose, a cleaning box 22 is installed in the housing 1, the top of the cleaning box 22 is open, and a glue cleaning agent is stored in the cleaning box 22. Wiping cotton 23 is fixed to the symmetrical inner walls of the cleaning box 22, and the wiping cotton 23 is soaked in the glue cleaning agent.

[0042] See also Figure 2 In order to further facilitate the driving roller 20 to be immersed in the cleaning box 22, a driving member is installed in the housing 1. The driving member is a cylinder 24, which is fixed to the inner bottom wall of the housing 1, and the telescopic end of the cylinder 24 is fixedly connected to the bottom surface of the cleaning box 22.

[0043] Also, see Figure 2 In order to facilitate the wiping cotton 23 to wipe the driving roller 20, a clearance hole 25 is opened on the opposite side of the two wiping cottons 23, and the driving roller 20 is interference-fitted with the clearance hole 25.

[0044] When the cylinder 24 is started, the telescopic end of the cylinder 24 drives the cleaning box 22 to rise, so that the driving roller 20 is inserted into the clearance hole 25, and the driving roller 20 is immersed in the glue cleaning agent. When the driving roller 20 rotates, the wiping cotton 23 cleans the roller wall of the driving roller 20 through the glue cleaning agent. After the driving roller 20 is wiped dry, the traction operation is performed again.

[0045] It should be noted that a control system is also installed in the casing 1. The control system is a control system in this field, and the control system is used to control all electrical equipment in the casing 1 to ensure the stable operation of the glue hanging machine.

[0046] The working principle of a sports glue hanging machine:

[0047] When the blanket needs to be glued, firstly, glue liquid is poured into the glue tank 7, and then the blanket is pre-threaded from the feed port 3 and passed out from the discharge port 4. Then, according to the thickness of the blanket to be glued, the hand wheel 18 is turned to adjust, and the hand wheel 18 drives the screw rod 17 to rotate, and the screw rod 17 drives the rod frame 15 to rise and fall through the connecting rod 16, and the rod frame 15 drives the pressure roller 13 to rise and fall at the same time, and under the pressing action of the pressure roller 13, the back of the blanket is pressed against the glue roller 8.

[0048] Then, the two driving rollers 20 are started by the control system. Under the traction of the driving rollers 20 and the friction between the blanket embryo and the glue coating roller 8, the glue coating roller 8 applies the glue in the glue tank 7 to the back of the blanket embryo. After the glue coating is completed, the blanket embryo passes through the brush plate 10 and squeezes the brush plate 10. Under the reaction force of the spring 11, the brush plate 10 is pressed against the back of the blanket embryo and scrapes the back of the blanket embryo, so that the glue is evenly applied to the back of the blanket embryo.

[0049] In summary, the brush plate 10 scrapes the back side of the carpet blank after the glue is applied, which is beneficial to improving the uniformity of the glue application.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
