Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be both elements in between.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to FIG. 1 , a cooling device according to an embodiment of the present invention includes a water tank 10 and a water removal device 30 . The water removal device 30 removes water from the workpiece cooled from the water tank 10 . In this embodiment, the workpiece is modified pellets 100 .

The water removing device 30 includes a conveyor belt 32, a water absorbing member 34, a driving member 36 and a water removing member 37, which are connected end to end. The driving member 36 can drive the conveyor belt 32 to circulate in one direction. 32 moves to absorb the water on the workpiece, and the water removing member 37 is arranged on the moving path of the conveyor belt 32 to squeeze the water absorbed by the water absorbing member 34 . When working, the workpiece is arranged on the moving path of the conveyor belt 32, the water absorbing member 34 is arranged on the side facing the workpiece, and the moving direction of the conveyor belt 32 is opposite to the moving direction of the workpiece, and the moving direction of the conveyor belt 32 is opposite to the moving direction of the workpiece. The water absorbing member 34 better absorbs the water on the workpiece. Specifically in this embodiment, the conveyor belt 32 is a belt.

When the workpiece comes out of the water tank 10, the water absorbing member 34 absorbs the water of the workpiece, and the water absorbing member 34 that has absorbed the water is brought to the water removing member 37 by the conveyor belt 32, the water is squeezed out, and then moves with the conveyor belt 32 to the workpiece to absorb water, so The cycle is reciprocating, so that the water can be recovered without going through other devices, avoiding the loss of water and secondary pollution.

Further, the water absorbing member 34 is provided on the outer side of the conveyor belt 32 . Specifically, the water absorbing member 34 is a sponge, and the sponge has good water absorption.

Further, the driving member 36 includes a first guide roller 361 and a second guide roller 362 arranged at intervals, the conveying belt 32 is wound around the first guide roller 361 and the second guide roller 362, and the first guide roller 361 is higher than the second guide roller 361. Roller 362. During operation, the water absorbing member 34 located at the first guide roller 361 is close to the workpiece to absorb water. Setting the first guide roller 361 higher than the second guide roller 362 can prevent the water at the second guide roller 362 from flowing to the first guide roller 361 .

Further, the line connecting the contact points of the water removing member 37 , the first guide roller 361 and the second guide roller 362 and the conveyor belt 32 forms a triangle, and the water removing member 37 is higher than the first guide roller 361 and the second guide roller 362 .

Further, the angle between the transmission belt 32 between the water removing member 37 and the first guide roller 361 and the vertical direction is greater than the angle between the conveying belt 32 and the vertical direction between the water removing member 37 and the second guide roller 362 . In this way, it can be ensured that the water squeezed by the water removing member 37 flows toward the second guide roller 362 instead of the first guide roller 361, preventing the water absorbing member 34 that has just squeezed out from absorbing the squeezed water. , reducing the water absorption capacity of the water absorbing member 34 .

Further, the water removing member 37 includes two pressing rollers 371, the two pressing rollers 371 are respectively located on both sides of the conveyor belt 32 and the water absorbing member 34, and the conveyor belt 32 and the water absorbing member 34 are sandwiched therebetween, and the minimum distance between the two pressing rollers 371 is The gap is smaller than the sum of the thicknesses of the conveyor belt 32 and the absorbent member 34 . When the water-absorbing part of the water-absorbing member 34 reaches between the two pressing rollers 371 along with the conveyor belt 32 , the pressing roller 371 squeezes the water-absorbing member 34 to squeeze out the water, so that the water can return to the water tank 10 .

Further, both of the two pressing rollers 371 can be rotated, and the rotation directions of the two pressing rollers 371 are opposite, so as to form a better squeezing of the water absorbing member 34, which is beneficial to the squeezing of water. It can be understood that the two pressing rollers 371 can also be set to not rotate, or only one of the pressing rollers 371 can be rotated.

Further, the moving direction of the conveyor belt 32 is from the first guide roller 361 to the second guide roller 362 , and the first guide roller 361 , the second guide roller 362 and the pressing roller 371 located inside the conveyor belt 32 rotate in the same direction and are located on the conveyor belt 32 . The rotation direction of the outer pressing roller 371 is opposite to the rotation direction of the first guide roller 361 and the second guide roller 362 . In this way, the water absorbing member 34 coming from the second guide roller 362 enters between the two pressing rollers 371 from the direction in which the two pressing rollers 371 are intertwined and squeezed, so that the water is squeezed out from the side close to the second guiding roller 362. Flow to the second guide roller 362 to prevent water from being squeezed out and then flow to the first guide roller 361 .

The water removing device 30 of the cooling equipment of the present invention is provided above one end of the water tank 10 . In this way, the water squeezed by the water removing member 37 flows back into the water tank 10, avoiding the loss of cooling water, and the water only passes through the water absorbing member 34 without passing through other equipment, so there is no secondary pollution.

Further, the cooling device further includes a guide member 50, and the guide member 50 can guide the workpiece upward in the moving direction. Specifically, the guide member 50 includes two rotating rollers, and the rotating rollers in the upstream and downstream in the moving direction of the workpiece are higher than the upstream rotating rollers. In this way, the workpiece can be led out of the water in the water tank 10 to the water surface to reach the first guide roller 361 for water absorption.

The water removing device 30 of the present invention can realize the automatic water absorption and automatic water removal of the water absorbing member 34, and the equipment is simple, and the removed water can be recovered in time, which not only saves the use of water, but also prevents secondary pollution.

The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
