Description

Technical Field

[0001] The present invention relates to the technical field of wooden floor production, and in particular to a highly stable waterproof MGO floor production device and a production process thereof. Background Art

[0002] The processing of the floor requires multiple steps, and the hot pressing forming process is an important component, which requires the use of a forming device. A Chinese invention patent with application announcement number CN212707661 U discloses an SPC floor forming device, including a conveying frame, and a transmission roller is rotatably set between the two opposite columns of the conveying frame. Support columns are fixedly set on both sides of the top of the hot pressing workbench. The two support columns are interlaced with the movable plate. The middle part of the bottom end of the movable plate is threadedly connected to the heating plate, the bottom end of the top plate is fixedly provided with a hydraulic push rod, and the middle part of the top end of the conveying frame is fixedly provided with a roller coating mechanism. The beneficial effect of this utility model is that through the stepping motor, glue roller and feeding box, it is convenient to automatically apply glue to the floor, ensure the uniformity of the application, eliminate the need for manual application, and reduce the intensity of labor.

[0003] However, the inventors found that during the production process of the existing equipment, the glue in the feeding box of the equipment kept flowing out to the glue coating roller when the equipment was running, resulting in excessive and uneven application of glue during the gluing process; the floor directly entered the hot pressing workbench after gluing, and positional deviation was prone to occur during the pressing process, resulting in a low product qualification rate. Summary of the Invention

[0004] One of the purposes of the present invention is to address the shortcomings of the existing technology. By setting the lower end of the glue box to an arc surface with the same diameter as the glue coating roller, the glue box can fit with the glue coating roller when the glue coating stops, so that the glue will not overflow, which solves the problem that the glue in the feeding box of the above-mentioned equipment flows out to the glue coating roller when the equipment is running, resulting in excessive and uneven application of glue during the gluing process; by sliding a lifting assembly on the support platform, when the lifting assembly moves to the lifting section, the glued wooden board a is lifted up, so that it is initially pressed with the wooden board b, and then enters the pressing assembly. The left end of the pressing assembly guides and corrects the two, which solves the problem that the floor directly enters the hot pressing workbench after gluing, and is prone to position deviation during the pressing process, resulting in a low product qualification rate.

[0005] In view of the above technical problems, the technical solutions adopted by the present invention are as follows:

[0023] 2.

When it enters the pressing assembly, the left end of the pressing assembly guides and corrects the two, which is beneficial to improving the qualified rate of the product.

[0024] 3. In the present invention, by arranging top blocks on both sides of the front and rear of the support platform, the support platform lifts the push block through the top blocks during the movement, thereby driving the glue box to rise and allowing the glue to flow from the glue outlet to the glue coating roller, avoiding the glue from flowing out continuously and causing too much glue on the glue coating roller, so that the glue coating roller can apply glue more evenly.

[0025] In summary, the equipment has the advantages of uniform glue coating and improved product qualification rate, and is particularly suitable for the field of wooden floor production technology. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame a1 is provided with a rotary mechanism a3, the support frame b2 is provided with a rotary mechanism b4, the rotary mechanism a3 is provided with a plurality of support platforms 5, the support platforms 5 are slidably provided with a lifting component 6, the rotary mechanism b4 is provided with a negative pressure component 7, the support frame a1 is provided with a glue coating component 8, a placement platform 20 and a pressing component 10 from left to right, the placement A cylinder 50 for pushing the wooden board b40 is provided on the platform 20, and a guide rail 9 is provided in the middle part of the support frame a1. The rotating mechanism a3 drives the wooden board a30 to rotate, and the rotating mechanism b4 drives the wooden board b40 to rotate through the action of the negative pressure component 7. The wooden board a30 is glued under the action of the gluing component 8, and the wooden board a30 and the wooden board b40 are pressed together through the lifting action of the lifting component 6, and the wooden board a30 and the wooden board b40 are heated and pressurized by the pressing component 10 to complete the floor forming.

[0040] It is worth mentioning here that by sliding the lifting component 6 on the support platform 5, when the lifting component 6 moves to the lifting section 93, the wooden board a30 that has been coated with glue is lifted up, so that it is initially pressed together with the wooden board b40. When it enters the pressing component 10, the left end of the pressing component 10 guides and corrects the two, which is beneficial to improving the product qualification rate.

[0041] like Figure 2 As shown, the rotating mechanism a3 includes a rotating component a31 and a rotating component b32 arranged on the support frame a1, the rotating component a31 includes a motor a311 and a rotating chain a312 driven by the motor a311, the rotating component b32 includes a transmission shaft a321 and a rotating chain b322 driven by the transmission shaft a321, and the rotating component a31 and the rotating component b32 operate synchronously.

The fixed plate 81 is provided with a sliding groove 811 for the glue box 83 to slide. The diameter of the arc surface of the lower end of the glue box 83 is the same as the diameter of the glue coating roller 82. The lower end of the glue box 83 is provided with a glue outlet, and the front and rear sides of the glue box 83 are provided with pushing blocks 831 that cooperate with the top block 53.

[0051] It is worth mentioning here that by setting the lower end of the glue box 83 to an arc surface with the same diameter as the glue roller 82, the glue box 83 can fit with the glue roller 82 when the glue application stops, so that the glue material will not overflow, and the glue application of the glue roller is more uniform.

[0052] like Figure 7 As shown, the upper end portion of the guide rail 9 is provided with a glue coating section 91, a transition section 92, a lifting section 93 and a pressing section 94 in sequence from left to right.

After the wooden board a30 passes through the glue roller 82, it drives the roller to rotate and completes the gluing of the wooden board a30;

[0058] c. In the initial pressing process, when the rotary mechanism a3 drives the plank a30 to move to the transition section 92, the plank b40 is pushed to the lower end of the negative pressure plate 71 by the cylinder 50.

The lifting assembly 6 lifts the plank a30 through the lifting section 93, so that it completes the initial pressing with the plank b40.

[0065] The rotating mechanism a3 drives the wooden boards a30 and b40 to move to the pressing section 94, and the pressing of the wooden boards a30 and b40 is completed through the heating and pressurizing action of the pressing assembly 10. The wooden boards a30 and b40 moved to the right end of the rotating mechanism a3 are manually removed to complete the unloading and complete the floor forming.
