[0002] Floor covering is a kind of floor covering material, which is a rubber plastic product. It is one of the indispensable floor covering materials in the floor decoration of various workplaces and public places. In the past, traditional floor covering materials mostly used PVC plastic flooring, but PVC material has poor high temperature resistance and is easy to deform when working in a hot environment.

[0053] 8. The present invention provides structures such as connecting pipes, electric telescopic cylinders and extrusion plates. Since the connecting pipe is provided at the top of the first material chamber, during extrusion, the material must fill the space on the top of the extrusion plate before it can be output from the multiple connecting pipes to the second material chamber, thereby ensuring uniform supply of the material.

[0113] To improve the cleaning effect; Figure 7 As shown, a dust collecting device 31 is fixed to the top outer wall of the feeding support frame 13 by screws, and the position of the dust collecting device 31 is adapted to the containing groove 32;

[0114] By providing the dust suction device 31 , the cleaned impurities can be sucked and collected, so as to prevent the impurities from adhering to the brush head 33 and polluting the central filling layer A1 , thereby improving reliability.

[0115] In order to improve reliability; in the extrusion mechanism, the temperature of the extruder body 9 for heating the top surface layer A2 or the bottom surface layer A5 is: 130-135°C in zone 1; 135-140°C in zone 2, 140-145°C in zone 3, and 145-150°C in zone 4;

[0116] The temperature of the extruder body 9 for heating the upper adhesive layer A3 or the lower adhesive layer A4 is: 150-155°C in zone 1; 155-160°C in zone 2, 160-165°C in zone 3, and 165-170°C in zone 4;

[0117] The temperature of the head body 16 is 140-160°C.

[0118] When the present embodiment is in use, the feeding drive motor 17 drives the feeding roller 26 to rotate, feeds the center filling layer A1 coil, and delivers the raw materials to the two extruder bodies 9 through the feeding mechanism. The two raw materials are heated by the two extruder bodies 9 and delivered to the two first material chambers 20. After filling the first material chamber 20, they are evenly output to the second material chamber 22 through the connecting pipe 21, so that the two raw materials are respectively filled in the two second material chambers 22. As the extruder body 9 continues to work, the two raw materials are squeezed into the double-sided fusion channel 24 together. Since the bottom end of the partition 25 is a V-shaped structure, it can guide the materials to a certain extent, and finally the two materials can be bonded together with clear boundaries, thereby obtaining the bonded top surface layer A2 and the upper Adhesive layer A3, or bottom layer A5 and lower adhesive layer A4; the conveyed central filling layer A1 and the bonded top layer A2 and upper adhesive layer A3 or bottom layer A5 and lower adhesive layer A4 are connected at the bonding mechanism, and the top layer A2 and upper adhesive layer A3, or bottom layer A5 and lower adhesive layer A4 are bonded to one side of the central filling layer A1 through extrusion and auxiliary bonding by the bonding rollers 10 of the bonding mechanism, and the circulating water pump in the circulating water tank 5 works to cool the product being processed; the traction drive motor 8 works to pull and reel the product; after reeling, the single side of the central filling layer A1 is processed; the other side of the central filling layer A1 is processed in another floor leather production subsystem in the above manner to obtain the product. Example

[0120] By setting structures such as the connecting tube 21, the electric telescopic cylinder 39 and the extrusion plate 37, since the connecting tube 21 is set at the top of the first material chamber 20, during extrusion, the material must fill the space on the top of the extrusion plate 37 before it can be output from the multiple connecting tubes 21 to the second material chamber 22, thereby ensuring uniform supply of the material. By setting structures such as the electric telescopic cylinder 39 and the extrusion plate 37, the electric telescopic cylinder 39 can work to drive the extrusion plate 37 to extrude upward, so as to squeeze out the material in the first material chamber 20, thereby improving reliability.

[0121] Test 1:

[0122] In order to find out the difference between the floor leather of the present invention and the traditional PVC floor leather, the floor leather is processed by the production process system of the above floor leather, and the prepared floor leather is used as a test example. The common PVC floor leather on the market is selected as a control example. The two floor leathers are evaluated and the following conclusions are obtained:

[0123]

[0124] It can be seen from the above that the floor leather prepared by the present invention has obvious advantages over traditional PVC floor leather. It not only performs well in wear resistance, anti-slip property, flexibility and heat resistance, but is also more environmentally friendly. Moreover, at the same size, the production cost is lower, and it has good economic benefits.

[0125] Test 2:

[0126] In order to improve the quality of the floor leather of the present invention, the floor leather is processed by the production process system of the floor leather, and other conditions are controlled unchanged, and only the temperature of the head body is changed. The floor leather obtained is evaluated and the following conclusions are obtained:

[0127]

[0128] It can be seen from the above that the temperature of the head body has a certain influence on the product performance. Among them, when the temperature of the head body is 155°C, the product performance is optimal. Therefore, it is preferred to control the temperature of the head body at 155°C.

[0129] Test 3:

[0130] In order to improve the energy-saving and environmental protection effect of the process system of the present invention, two different methods are now used for processing;

[0131] Method 1: Processing through the above-mentioned floor leather production process system;

[0132] Method 2: Processing by traditional processing method, that is, first preparing the top surface layer A2, the upper adhesive layer A3, the bottom surface layer A5, and the lower adhesive layer A4 respectively, and then bonding and cutting;

[0133] The production costs were evaluated and the following conclusions were obtained (the higher the score, the lower the cost and the higher the benefit):

[0134]

[0135] As can be seen from the above, by adopting the process system of the present invention, the top surface layer A2 and the upper adhesive layer A3, and the bottom surface layer A5 and the lower adhesive layer A4 are directly extruded into one piece, eliminating the subsequent bonding and cutting steps of the traditional process, greatly saving production costs, and having good economic benefits.
