Detailed Description

Referring to fig. 1 and 2, the cold press comprises a frame 1, a base frame 2 and a pressure panel 3 driven by a pressure cylinder 4 to move up and down. The upper surface 21 of the base 2 is a work surface for placing a plate, and the middle part of the work surface that can be covered by the pressure panel 3 is a work area. The base 2 is provided with three grooves 12 parallel to each other in the longitudinal direction. The groove 12 extends from one side of the base to the other side in the width direction of the base 2. Each groove 12 is provided with a conveying chain 10, and the conveying chain 10 extends from one side of the base 2 in the width direction to a predetermined distance outside the base through the other side. The predetermined distance is sufficient to place the sheet material prior to cold pressing.

In particular, the extension of the conveyor chain 10 outside the base 2 is used for storing the slabs to be cold-pressed or the slabs already cold-pressed. The area corresponding to this extension, also called the blanking area (101 in fig. 3) of the cold press, is located on one side of the above-mentioned working area (102 in fig. 3).

Each conveyor chain 10 is looped around a corresponding elongated cross member 11. Preferably, the conveyor chain 10 is mounted within a recess of the cross beam 11. The cross beam 11 provides support and guidance for the conveyor chain 10. Every two of them are formed into a unit, and are supported by hydraulic cylinders 9 at two ends in the conveying direction, so that they can be synchronously lifted or lowered. Preferably, when the cross beam 11 moves upward to the highest point, the top surface of the conveying chain 10 is higher than the working surface 21 of the base; when the cross beam 11 moves down to the lowest point, the top surface of the conveyor chain 10 is below the working surface 21 of the base.

The driving motor 5 is disposed at a side of the base 2, and drives the driving shaft 6. The drive shaft 6 is engaged with three conveyor chains 10 at its axial upper, middle, and lower positions, respectively, to transmit a driving force.

Referring to fig. 1 and 3, the base 2 is further provided with connecting rods 7 at both sides thereof. Any one of the connecting rods 7 connects the three beams 11 together in the longitudinal direction, thereby forming a frame which intersects vertically and horizontally. Any one of the connecting rods 7 is provided with a gear 71 at any one axial end. Any one of the four gears 71 is meshed with a corresponding rack 8 arranged on the base 2, and is used for adjusting the flatness of the frame where the cross beam 11 is located, so that the top surfaces of all the conveying chains 10 are in the same plane. Therefore, six hydraulic cylinders supported below the three cross beams 11 can coordinate and uniformly bear force, and plate conveying is more stable.

For any one of the combinations of the cross beam 11 and the conveying chain 10, the liquid cylinders 9 are provided at the front end (upstream side) and the rear end (downstream side) in the plate conveying direction, respectively. The cylinder 9 on the upstream side is preferably provided in the widthwise middle of the blanking region 101, so that the blanking is more stable. The downstream cylinder 9 is preferably located laterally outwardly of the other side of the base for ease of installation and maintenance.

Figure 4 is the working principle schematic diagram of the conveying chain of the cold press of the utility model. Referring to fig. 4, the conveyor chain 10 is looped between the drive shaft 6 and an idler pulley 61 provided on the cross beam 11. When the drive shaft 6 rotates counterclockwise, the conveyor chain 10 is also brought to rotate counterclockwise. The plate member 100 is carried on the top surface of the conveyor chain 10, being conveyed in the direction toward the drive shaft 6.

Now the operating steps of the machine are introduced: firstly, the hydraulic cylinder 9 raises the conveying chain 10 to a fixed height; then, putting the whole card of the material to be cold-pressed into a position corresponding to the blanking area 101 on the conveying chain 10; then the driving motor 5 drives the driving shaft 6, and then drives the conveying chain 10 to convey the material to the working area 102; after the conveying is finished, the hydraulic cylinder 9 releases the pressure, and the conveying chain 10 and the cross beam 11 synchronously descend to the bottom of the groove 12; the pressure cylinder 4 drives the pressure panel 3 to press the material to be pressed in a heavy-duty manner, i.e. the material is pressed between the pressure panel 3 and the working surface 21 in a heavy-duty manner. After pressing, the pressure panel 3 is driven by the pressure cylinder 4 to retract to the highest safety height, and the materials subjected to cold pressing are released; secondly, the hydraulic cylinder 9 raises the conveying chain 10 to a preset height, so that the material is normally supported by the conveying chain 10; finally, the drive motor 5 drives the conveyor chain 10 to return the material to the blanking area 101.

It should be noted that the above description of the width direction, the longitudinal direction, etc. of the machine or the machine base is only used for defining coordinates to describe the orientation more clearly, and does not constitute a strict limitation on the dimensions, i.e. the width dimension is not necessarily smaller than the longitudinal dimension.

Also, there are many variations of the above embodiment, for example, the conveying chain 10 may omit the middle one, or arrange several. The conveyor chain 10 may be driven simultaneously by two drive shafts at both ends, etc.

It should be emphasized that the present invention is not limited to the above-described embodiments, but only the preferred embodiments of the invention are described above, and the present invention is not limited to the above-described embodiments, and any modifications, equivalent substitutions, improvements and the like within the spirit and principle of the present invention should be included in the scope of the present invention.
