Description

TECHNICAL FIELD

[0001] The utility model is suitable for carpet production technical field, especially relates to a gluing mechanism for carpet production. BACKGROUND

[0002] At present, the carpet is the ground paving material which is made of natural fiber or chemical synthetic fiber raw materials such as cotton, hemp, wool, silk, grass yarn, etc. and is knitted, planted or woven by hand or mechanical process. In the processing of the carpet, the carpet is generally placed on the conveying mechanism, the conveying mechanism drives the carpet to move to the lower side of the gluing mechanism, the glue is sprayed to the surface of the carpet in combination with the conveying of the gluing nozzle, and then the gluing processing of the carpet is realized.

[0003] However, when the carpet is currently glued, the distance between the gluing nozzle above and the surface of the carpet cannot be adjusted in adaptability for the carpet of different thickness and size, and then once the position of the gluing nozzle is too far from the surface of the carpet, the distance of the gluing nozzle for discharging the glue is too long, the glue is randomly scattered to other positions of the carpet, and the gluing quality of the surface of the carpet is affected. Therefore, we propose a gluing mechanism for carpet production. CONTENT OF THE UTILITY MODEL

[0004] The main purpose of the utility model is to provide a gluing mechanism for carpet production, which can effectively solve the problems in the background art.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A gluing mechanism for carpet production, comprising a conveying table, a conveying drum is rotatably installed inside the conveying table, an installation frame is fixedly installed on the top surface of the outer side of the conveying table;

[0008] A feeding pipe is fixedly installed on both sides of the top of the installation frame in a vertical manner, a corrugated hose is fixedly communicated with the bottom surface of each feeding pipe, a collecting pipe is fixedly communicated in a horizontal manner between the bottoms of two groups of corrugated hoses, a fixed sleeve is fixedly sleeved on the outer side of both ends of the collecting pipe, and the bottom of the push rod is hingedly connected to the top of the outer side of the fixed sleeve through a rotating shaft.

[0009] By adopting the above technical solution, the rotational transmission of the transmission sleeve by the bidirectional screw and the conversion of the horizontal moving force of the transmission sleeve into a vertical pushing and pulling force on the fixed sleeve and the collecting pipe by the push rod, the collecting pipe and the glue spraying nozzle below it move vertically in sync. This adjusts the distance between the glue spraying nozzle and the surface of the conveying roller, preventing the distance between the carpet to be glued on the surface of the conveying roller and the glue spraying nozzle from being too large, which would cause the glue to spray too far and spread randomly, affecting the uniformity of the glue application on the carpet surface.

[0010] As an optional solution to the technical solution of this application, a servo motor is fixedly installed on the outer surface of the hollow frame, and the side of the servo motor drive shaft is fixedly connected to the outer top surface of the bidirectional lead screw through a coupling.

[0011] By adopting the above technical solution, the power source required for the rotation of the bidirectional lead screw can be provided by the drive of the servo motor.

[0012] As an optional solution to the technical solution of this application, an installation plate is slidably installed in the middle of the inner side of the installation frame, and an adhesive spray nozzle is fixedly installed on the bottom surface of the installation plate. The number of adhesive spray nozzles is several sets. The adhesive spray nozzles are located above the outer side of the conveying roller. A conveying pipe is vertically fixedly installed inside the installation plate, and the number of conveying pipes is the same as the number of adhesive spray nozzles. The bottom of the conveying pipe is connected to the feed port at the top of the adhesive spray nozzle.

[0013] By adopting the above technical solution, the corrugated hose can ensure that the glue can still be transported and used after the collection pipe moves vertically.

[0014] As an optional solution to the technical solution of this application, a limiting groove is provided at the bottom center of the hollow frame, and the connecting bracket is slidably inserted into the limiting groove.

[0015] By adopting the above technical solution, the rationality of the transmission adjustment of the entire device is ensured by the guiding and limiting effect of the limiting groove on the connecting frame.

DETAILED DESCRIPTION

[0023] As shown in Figures 1-3 , the technical scheme of the application provides a glue applying mechanism for carpet production, a servo motor 25 is fixedly installed on the outer side surface of the hollow frame 2, and the transmission shaft side of the servo motor 25 is fixedly connected with the outer side top end surface of the bidirectional screw rod 21 through a shaft coupling.

[0024] In the technical scheme (through Figure 1 , Figure 2 and Figure 3As shown, a limiting groove 4 is provided at the bottom center of the hollow frame 2, and the connecting frame 23 is slidably inserted into the limiting groove 4. The hollow frame 2 is fixedly installed on the top surface of the inner side of the mounting frame 12. A bidirectional lead screw 21 is installed inside the hollow frame 2 by rotating laterally through a bearing. Both ends of the bidirectional lead screw 21 are movably sleeved with transmission sleeves 22. A connecting frame 23 is fixedly installed on the bottom surface of the outer side of each transmission sleeve 22, and the connecting frame 23 is slidably inserted into the bottom end of the transmission frame. A push rod 24 is hinged to the bottom surface of each connecting frame 23 through a rotating shaft.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, feed pipes 26 are vertically fixedly installed on both sides of the top of the mounting frame 12. Corrugated hoses 27 are fixedly connected to the bottom surface of each feed pipe 26. A collection pipe 28 is horizontally fixedly connected between the bottoms of two sets of corrugated hoses 27. Fixed sleeves 29 are fixedly sleeved on both outer ends of the collection pipe 28. The bottom of the push rod 24 is hinged to the top of the outer side of the fixed sleeve 29 through a rotating shaft. A mounting plate 31 is slidably installed in the middle of the inner side of the mounting frame 12. A glue spray nozzle 32 is fixedly installed on the bottom surface of the mounting plate 31. There are several sets of glue spray nozzles 32. The glue spray nozzles 32 are located above the outer side of the conveying roller 11.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a conveying pipe 3 is vertically fixedly installed inside the mounting plate 31, and the number of conveying pipes 3 is the same as the number of glue spray nozzles 32. The bottom of the conveying pipe 3 is connected to the top inlet of the glue spray nozzle 32.

[0027] During operation, the carpet to be coated with adhesive is placed flat on the surface of the conveyor roller 11. Then, the servo motor 25 is turned on by the external control switch, causing it to rotate and drive the bidirectional lead screw 21 to rotate. With the guiding and limiting effect of the limiting groove 4 on the connecting frame 23, the transmission sleeve 22 sleeved on the surface of the bidirectional lead screw 21 can move synchronously towards each other. Then, under the transmission conversion effect of the push rod 24, the horizontal moving force of the transmission sleeve 22 can be converted into a vertical pushing force on the collecting pipe 28, which in turn drives the collecting pipe 28 and the adhesive spray nozzle 32 connected below it to descend vertically synchronously until the adhesive spray nozzle 32 is close to the surface of the carpet placed on the surface of the conveyor roller 11. With the deformation and connection effect of the corrugated hose 27, the adhesive to be sprayed is conveyed from the feed pipe 26 to the inside of the adhesive spray nozzle 32. Under the spraying action of the adhesive spray nozzle 32, the adhesive is evenly sprayed onto the carpet surface, completing the adhesive coating process on the carpet surface.
