[0002] The general wood plastic floor includes four layers, which are wear-resistant layer, decorative layer, base material layer and balance layer from top to bottom. The processing of the decorative layer is to soak the colored or textured decorative paper in adhesive, and then lay it on the base material layer after it dries and solidifies. In order to improve the adhesion of the decorative layer, it is necessary to lay the decorative paper through hot pressing process. However, the general hot pressing equipment has the disadvantage of low automation, and the floor needs to be placed manually, which makes it easy for the adhesive to stick to the hands.

[0012] (III) Beneficial effects

[0013] The beneficial effects of the utility model are:

[0014] (1) During operation, the floor covered with decorative paper in the previous process is placed in the clamping unit. As the sprocket rotates, the clamping unit is driven to rotate until it rotates to the bottom of the hot pressing plate. At this time, the hot pressing plate heat-presses the floor until the floor is completely compressed. After a period of time, the hot pressing plate moves upward and leaves the floor. Then the sprocket transfers the hot-pressed floor to the next process, completing the hot pressing process of the floor decorative layer. This solves the shortcomings of low automation in general hot pressing equipment, which requires manual placement of the floor and is easy to get adhesive on the hands. In addition, due to the high temperature after hot pressing, the floor needs to be cooled before it can be transferred, which prolongs the operation time and reduces work efficiency. In addition, in order to save time, some hot pressing equipment often overlaps multiple pieces of floor and then performs hot pressing, which will cause uneven force on the upper and lower floors and cannot guarantee the uniformity of hot pressing quality.

[0015] (2) The heating controller first heats the hot pressing plate, and then the first cylinder output shaft moves downward to drive the hot pressing plate 16 to move downward to complete the hot pressing process of the floor decoration layer.

[0016] (3) When the floor is placed on the support plate, since the clamping block passes through one end of the mounting block and is formed with an arc surface above, and an L-shaped slot is opened at the bottom, the floor can be clamped by the clamping block by pressing downward at this time. When the hot pressing plate moves downward for hot pressing, the first unlocking rod also moves downward. An unlocking groove is opened on the upper surface of the clamping block, and a first inclined surface is formed on one side of the unlocking groove. The first unlocking rod is vertically fixed at a position corresponding to the unlocking groove on the lower surface of the hot pressing plate, and a second inclined surface is formed at the bottom end of the first unlocking rod. The first unlocking rod moves downward so that the first inclined surface and the second inclined surface abut against each other. At this time, the clamping block moves outward and no longer clamps the floor. At the same time, the hot pressing plate moves downward to complete the hot pressing process of the floor decoration layer, thereby preventing the clamping block from interfering with the hot pressing of the hot pressing plate.

[0017] (4) When unloading is required, the second cylinder output shaft moves upward to drive the fourth mounting plate to move upward, and the fourth mounting plate moves upward to drive the second unlocking rod to move upward. An unlocking groove is provided on the upper surface of the clamping block, and a first inclined surface is formed on one side of the inner part of the unlocking groove. A second unlocking rod is vertically fixed on the upper surface of the fourth mounting plate and at a position corresponding to the unlocking groove. A third inclined surface is formed on the top of the second unlocking rod. The second unlocking rod moves upward to make the first inclined surface and the third inclined surface abut against each other. At this time, the clamping block moves outward and no longer clamps the floor. At the same time, the floor with the completed floor decoration layer falls from the unloading chute to complete the unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model of a hot pressing device for paving a floor decoration layer is further described in conjunction with the accompanying drawings.

[0024] Combined with Figure 1-3 As shown, a hot pressing device for laying a floor decorative layer includes a frame 1 and support legs 2. The frame 1 is fixed on the support legs 2. Sprockets 3 are installed at both ends of the frame 1. A chain 4 is sleeved on the outer circumferential surface of the sprocket 3. A motor 21 for driving the sprocket 3 to rotate is fixed at one end of the frame 1. A hot pressing device 5 for hot pressing the floor decorative layer is arranged on the chain 4. The hot pressing device 5 includes a bracket 6. A hot pressing mechanism 7 is arranged on the bracket 6 and above the chain 4. A feeding mechanism 8 is arranged on the bracket 6 and below the chain 4. A support frame 9 is fixed on the frame 1 and between the hot pressing mechanism 7 and the feeding mechanism 8.

[0025] It should be noted that, during operation, the floor covered with decorative paper in the previous process is placed in the clamping unit, and as the sprocket 3 rotates, the clamping unit is driven to rotate until it rotates to the bottom of the hot pressing plate 16. At this time, the hot pressing plate 16 hot presses the floor until the floor is completely pressed. After a period of time, the hot pressing plate 16 moves upward and leaves the floor, and then the sprocket 3 transfers the hot-pressed floor to the next process, that is, the hot pressing process of the floor decorative layer is completed, which solves the shortcomings of low automation in general hot pressing equipment, requiring manual placement of the floor, and easily getting the adhesive on the hands. In addition, due to the high temperature after hot pressing, the floor needs to be cooled before being transferred, which prolongs the operation time and reduces work efficiency. In addition, in order to save time, some hot pressing equipment often overlaps multiple pieces of floor and then hot presses them, which will cause uneven force on the upper and lower floors, and the uniformity of the hot pressing quality cannot be guaranteed.

[0026] Combined with Figure 2 As shown, the hot pressing mechanism 7 includes a plurality of clamping units arranged on the chain 4, the clamping unit includes a support plate 10 fixed on the chain 4, a plurality of clamping components 11 are evenly distributed on the support plate 10, a first mounting plate 12 is fixed to the top of the bracket 6, a second mounting plate 13 is fixed to the middle of the bracket 6, a heating controller 14 is fixed to the first mounting plate 12, a pair of first cylinders 15 are vertically fixed to the second mounting plate 13, the output shaft of the first cylinder 15 passes through the second mounting plate 13 and a hot pressing plate 16 is fixed to the output shaft end of the first cylinder 15, and the hot pressing plate 16 is connected to the heating controller 14 through electric wires.

[0027] It should be noted that the heating controller 14 heats the hot pressing plate 16 first, and then the output shaft of the first cylinder 15 moves downward to drive the hot pressing plate 16 to move downward to complete the hot pressing process of the floor decoration layer.

[0028] Combined with Figure 3 As shown, the clamping assembly 11 includes a mounting block 1101 fixed on the support plate 10, a pair of slide bars 1102 are horizontally fixed on one side of the mounting block 1101, a slide plate 1103 is inserted on the slide bar 1102, a clamping block 1104 is horizontally fixed on the slide plate 1103, the clamping block 1104 passes through the mounting block 1101, and the clamping block 1104 passes through the mounting block 1101. The upper end is formed with an arc surface, and the lower end is provided with an L-shaped bayonet, and one end of the slide bar 1102 is fixed with a stopper Plate 1105, a return spring 1106 is sleeved on the slide rod 1102 and is located between the mounting block 1101 and the slide plate 1103, an unlocking groove 1107 is provided on the upper surface of the clamping block 1104, a first inclined surface is formed on one side of the inner part of the unlocking groove 1107, a first unlocking rod 1108 is vertically fixed on the lower surface of the hot pressing plate 16 and at a position corresponding to the unlocking groove 1107, a second inclined surface is formed on the bottom end of the first unlocking rod 1108, and the first inclined surface and the second inclined surface can abut against each other.

[0029] It should be noted that when the floor is placed on the support plate 10, since the clamping block 1104 passes through one end of the mounting block 1101 and has an arc-shaped surface above it and an L-shaped slot below it, pressing the floor downward at this time can cause the clamping block 1104 to clamp the floor. When the hot pressing plate 16 moves downward for hot pressing, the first unlocking rod 1108 also moves downward. An unlocking groove 1107 is provided on the upper surface of the clamping block 1104, and a first inclined surface is formed on one side of the unlocking groove 1107. A first unlocking rod 1108 is vertically fixed at a position corresponding to the unlocking groove 1107 on the lower surface of the hot pressing plate 16, and a second inclined surface is formed at the bottom end of the first unlocking rod 1108. The first unlocking rod 1108 moves downward so that the first inclined surface and the second inclined surface abut against each other. At this time, the clamping block 1104 moves outward and no longer clamps the floor. At the same time, the hot pressing plate 16 moves downward to complete the hot pressing process of the floor decorative layer, thereby preventing the clamping block 1104 from interfering with the hot pressing of the hot pressing plate 16.

[0030] Combined with Figure 2 As shown, the unloading mechanism 8 includes a third mounting plate 17 fixed to the bottom of the bracket 6, and a pair of second cylinders 18 with output shafts vertically upward are fixed on the third mounting plate 17. The output shaft of the second cylinder 18 passes through the third mounting plate 17 and a fourth mounting plate 19 is fixed to the end of the output shaft of the second cylinder 18. A second unlocking rod 22 is vertically fixed on the upper surface of the fourth mounting plate 19 and at a position corresponding to the unlocking groove 1107. A third inclined surface is formed on the top of the second unlocking rod 22, and the first inclined surface and the third inclined surface can abut against each other.

[0031] It should be noted that when unloading is required, the output shaft of the second cylinder 18 moves upward, driving the fourth mounting plate 19 to move upward, and the fourth mounting plate 19 moves upward, driving the second unlocking rod 22 to move upward. An unlocking groove 1107 is provided on the upper surface of the clamping block 1104, and a first inclined surface is formed on one side of the inner part of the unlocking groove 1107. A second unlocking rod 22 is vertically fixed on the upper surface of the fourth mounting plate 19 and at a position corresponding to the unlocking groove 1107. A third inclined surface is formed on the top of the second unlocking rod 22. The second unlocking rod 22 moves upward so that the first inclined surface and the third inclined surface abut against each other. At this time, the clamping block 1104 moves outward and no longer clamps the floor. At the same time, the floor with the completed floor decoration layer falls from the unloading chute 20, and the unloading is completed.

[0032] Combined with Figure 2 As shown, a material discharge chute 20 is provided through the third mounting plate 17 and the fourth mounting plate 19 .

[0033] Combined with Figure 1 As shown, the number of clamping units is at least four.

[0034] Working principle: during operation, the floor covered with decorative paper in the previous process is placed in the clamping unit. As the sprocket 3 rotates, the clamping unit is driven to rotate until it rotates to the bottom of the hot pressing plate 16. At this time, the hot pressing plate 16 hot presses the floor until the floor is completely pressed. After a period of time, the hot pressing plate 16 moves upward and leaves the floor. Then the sprocket 3 transfers the hot-pressed floor to the next process, that is, the hot pressing process of the floor decorative layer is completed, which solves the shortcomings of low automation in general hot pressing equipment. The floor needs to be placed manually, and the adhesive is easy to stick to the hands. In addition, due to the high temperature after hot pressing, the floor needs to be cooled before it can be transferred, which prolongs the operation time and reduces work efficiency. In addition, in order to save time, some hot pressing equipment often overlaps multiple pieces of floor and then hot presses them. This will cause uneven force on the upper and lower floors, and the uniformity of the hot pressing quality cannot be guaranteed.

[0035] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary personnel in this field should fall within the protection scope of the present invention.
