Description

Technical Field

[0001] The utility model relates to the field of carpet covering devices, in particular to a tufted carpet covering device. Background Art

[0002] Tufted carpet is a machine-made carpet that uses tufting machine needles to mechanically tuft pile on a chemical fiber fabric backing to form a loop pile or cut pile carpet surface. During carpet production, in order to increase the stability of the carpet, it is usually covered with a base layer. When the base layer is covered to the bottom of the carpet, it is usually rolled with a layer of glue and then connected to the bottom of the carpet.

[0003] Conventionally, a pressing method is usually adopted to connect the base layer to the tufted carpet. However, if the carpet is not flattened during direct pressing, the quality of the formed carpet will be affected.

[0004] In order to solve the above problems, this application proposes a tufted carpet bottom covering device. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] like Figure 1-3 As shown, the present invention provides a tufted carpet covering device, comprising a support platform 1, with an opening 101 formed on one side of the support platform 1;

[0024] Inside the opening 101 is provided a lifting mechanism 2 for supporting and heating the bottom layer 7;

[0025] A transmission rack 3 is fixedly mounted on the support platform 1 , a mounting frame 4 is fixedly mounted on the support platform 1 , a driving member 5 is fixedly mounted on the mounting frame 4 , and a tensioning mechanism 6 that transmits power to the transmission rack 3 is provided on the driving rod of the driving member 5 .

[0026] Specifically, the lifting mechanism 2 includes a linear actuator 21, a support plate 22 and a heating plate 23. The linear actuator 21 is fixedly installed inside the opening 101. The driving rod of the linear actuator 21 is fixedly connected to the support plate 22. The heating plate 23 is fixedly installed on the top of the support plate 22.

[0027] In order to increase the stability of the horizontal position of the support plate 22 and the smoothness of its vertical movement, balls that roll with the opening 101 are rotatably sleeved on both sides of the support plate 22 .

[0028] Specifically, the tensioning mechanism 6 includes a mounting plate 61, a rotating plate 62 and a rotating tube 63. The mounting plate 61 is fixedly mounted on the driving rod of the driving member 5. One end of the rotating plate 62 is rotatably connected to the mounting plate 61 through a torsion spring rotating shaft 65. The other end of the rotating plate 62 is rotatably connected to the rotating tube 63 through a rotating rod. The rotating rod is transmission-connected to the rack 3. A rubber sleeve is sleeved on the outer periphery of the rotating tube 63. Two symmetrically arranged threaded grooves are provided on the rubber sleeve. A transmission gear 64 is fixedly sleeved on the rotating rod, and the transmission gear 64 is transmission-connected to the rack 3.

[0029] It should be noted that the torsion spring shaft 65 includes a shaft and a torsion spring movably sleeved on the outer circumference of the shaft, and the mounting plate 61 is connected to the rotating plate 62 via the shaft and the torsion spring.

[0030] Under the action of the heating plate 23 , the bottom layer 7 is auxiliary heated so that the surface of the bottom layer is not dried, thereby facilitating the tightening of the thread groove on the rotating tube 63 .

[0031] In an optional embodiment, a roller 9 is rotatably provided on the rotating plate 62 .

[0032] It should be noted that, under the action of the rotating roller 9 , the tufted layer 8 is assisted in being laid, and at the same time, it is beneficial for the tufted layer 8 to gradually cover the bottom layer 7 .

The linear actuator 21 drives the support plate 61 upward to move so that the tufted layer 8 contacts the rotating tube 63. The linear actuator 21 moves back and the torsion spring shaft 65 recovers to drive the rotating plate 62 to gradually rotate toward the vertical downward state. The transmission gear 64 rotates to drive the rotating tube 63 to rotate, so that the rotating tube 63 rotates, so that the tufted layer 8 is tightened in the length direction of the rotating tube 63 to increase the flatness of the connection between the tufted layer 8 and the bottom layer 7.
