Description

Technical Field

[0001] The utility model relates to the field of polymer material processing equipment, in particular to a drooling cooling tank for an extruder. Background Art

[0002] There are generally two types of materials for 3D printing. One is metal powder, and the other is wire made by processing plastic materials. When processing the wire, it is generally obtained by extruding, drawing, cooling and winding through an extruder. During the extrusion and drawing process, during the start-up stage and when a wire breakage fault occurs, a part of the material will flow out from the head of the machine in the form of drool. This drool usually directly falls to the ground and will be recycled and processed after the on-site personnel complete the drawing action. Because the plastic material has a slow cooling rate, usually when the on-site personnel process it, the accumulated drool is still very hot. To solve this problem, some current devices will install a special drool collection tank at the end of the cooling water tank for drawing, use the cooling water to cool and harden it, and reduce dust contamination. However, due to limited space, in actual use, sometimes because the drool accumulates too much and covers the bottom of the tank, the water flow is blocked, and even overflows to the workplace. Moreover, when the drool accumulates locally in a large amount, the temperature drops slowly, and the whole is relatively soft, making it difficult to take out from the tank. Summary of the Utility Model

[0003] The main technical problem to be solved by the utility model is to provide a drooling cooling tank for an extruder, which can change the drool receiving position according to needs and facilitate the treatment of drool.

[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a drooling cooling tank for an extruder. The drooling cooling tank for an extruder is installed on the top of the cooling water tank of the extruder and is located directly below the head of the extruder. The drooling cooling tank for an extruder includes: a tank body, a water filtering baffle and a water return structure. The tank body is surrounded by a bottom plate, two side tank plates on both sides, a front tank plate and a rear tank plate. The width of the bottom plate is 1.5 - 2 times the width of the cooling water tank of the extruder. The front tank plate is higher than the rear tank plate. The top of the front tank plate is vertically folded outward to form a buckling plate. An L-shaped plate is fixedly installed at the bottom of the cooling water tank. The L-shaped plate and the bottom of the cooling water tank enclose a chute matching the buckling plate. Baffle slots are symmetrically arranged on the inner sides of the two side tank plates facing each other. The water filtering baffle is higher than the depth of the tank at the position of the baffle slots. When the water filtering baffle is inserted into the baffle slots, the protruding part just abuts against the lower part of the end face of the cooling water tank of the extruder, and together with the L-shaped plate, it clamps the position of the tank body. The water filtering baffle divides the tank body into two parts. The area between the water filtering baffle and the front tank plate is the water return area, and the area between the water filtering baffle and the rear tank plate is the drool cooling area. An outlet is arranged at the bottom of the water return area, and a water return structure is arranged below the outlet.

[0005] In a preferred embodiment of the present utility model, the water filter baffle is 3 - 5 cm higher than the depth of the slot of the baffle slot.

[0006] In a preferred embodiment of the present utility model, the water filter baffle includes a filter plate area and a baffle area. A plurality of filter holes are provided in the filter plate area. The baffle area is located at the top of the filter plate area, and limit clamping blocks are symmetrically arranged on both sides of the top of the baffle area.

[0007] In a preferred embodiment of the present utility model, the top end of the snap - on plate is a rounded - corner structure.

[0008] In a preferred embodiment of the present utility model, the return water structure includes a communication groove, a return water joint and a return water pipe. There are multiple water outlets in total. The communication groove is installed under the bottom plate to connect all the water outlets together. A return water joint is installed at the bottom of the communication groove, and the return water joint is connected to the return water pipe.

[0009] In a preferred embodiment of the present utility model, the return water pipe is a steel wire hose.

[0010] In a preferred embodiment of the present utility model, a condenser is further provided directly above the extrusion drooling cooling tank. The condenser is located in the space between the extrusion head and the top negative - pressure air hood of the extruder, and the lowest point of the condenser is aligned with the extrusion drooling cooling tank.

[0011] The beneficial effects of the present utility model are as follows: The present utility model is a transformation of the existing drooling cooling and collecting tank structure. By changing the width of the bottom plate and changing the simple fixed - connection relationship between the tank body and the cooling water tank into a relationship that can move horizontally relative to each other, in actual use, the tank body can be pushed according to the drooling situation to change the drooling position of the bottom plate. On the one hand, the overall drooling capacity is increased, effectively preventing blockage in the tank and preventing water from overflowing outside the tank. On the other hand, it reduces the problem that the hardening speed is slow and it is not easy to take out caused by excessive local drooling accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , the embodiments of the present utility model include:

[0021] A drooling cooling tank for an extruder, the drooling cooling tank for an extruder is installed relying on the top of the cooling water tank 1 of the extruder and is located directly below the extruder head. The drooling cooling tank for an extruder includes: a tank body 2, a water - filtering baffle 3 and a water - returning structure. The tank body 2 is surrounded by a bottom plate 202, two side groove plates 204 on both sides, a front groove plate and a rear groove plate 203. The front groove plate is higher than the rear groove plate 204. The top of the front groove plate is vertically folded outward to form a snap - on plate 201. The top end of the snap - on plate 201 is a rounded - corner structure that can prevent on - site operators from touching. An L - shaped plate 4 is welded to the bottom of the cooling water tank 1. The L - shaped plate 4 and the bottom of the cooling water tank 1 enclose a chute that matches the snap - on plate 201. Baffle slots 206 are symmetrically arranged on the opposite inner sides of the two side groove plates 204. The water - filtering baffle 3 is about 3 cm deeper than the depth of the slot at the position higher than the baffle slot 206. When the water - filtering baffle 3 is inserted into the baffle slot 206, the protruding part just abuts against the lower part of the end face of the extruder cooling water tank 1, and together with the L - shaped plate, it clamps the position of the tank body. The water - filtering baffle 3 divides the tank body 2 into two parts. The area between the water - filtering baffle 3 and the front groove plate is the water - returning area, and the area between the water - filtering baffle 3 and the rear groove plate 203 is the drooling cooling area. A water outlet is provided at the bottom of the water - returning area, and a water - returning structure is arranged below the water outlet.

[0022] The width of the bottom plate 202 is 1.5 - 2 times the width of the extruder cooling water tank 1. In actual implementation, generally 2 times the width of the cooling water tank 1 is taken, so that when pushing to switch positions, it can be completely switched just right and the overall occupied space is not large.

[0023] The water filter baffle 3 includes a filter plate area 303 and a baffle area 301. The filter plate area 303 is provided with a plurality of filter holes. The baffle area 301 is located at the top of the filter plate area 303. Limiting blocks 302 are symmetrically provided on both sides of the top of the baffle area 303. The positioning of the limiting blocks 302 at the top of the water filter baffle 3 can limit the range of movement of the tank body 1, preventing the tank body 1 from moving too far during switching and avoiding the extruder head.

[0024] The return water structure includes a connecting groove 5, a return water connector 6, and a return water pipe 7. There are three water outlets 205. The connecting groove 5 is installed below the base plate 202, connecting all the water outlets together. A return water connector 6 is installed at the bottom of the connecting groove 5, which is connected to the return water pipe 7. The return water pipe 7 is a steel hose. With this structure, cooling water, after being filtered by the filtered water baffle 3, can be discharged simultaneously downward through the three water outlets 205. After being connected through the connecting groove 5, it enters the circulation tank through the return water pipe 7. This prevents water accumulation in the tank and quickly removes heat from the saliva, causing it to harden and facilitate removal. The use of a steel hose in the return water pipe 7 allows the tank body 1 to repeatedly switch its saliva connection position without changing its inner diameter.

[0025] A condenser 8 is also provided directly above the trough body 2 of the extruder drool cooling trough. The condenser 8 is located in the space between the extruder head and the top negative pressure air hood, and the lowest point of the condenser 8 is aligned with the trough body. Because a large amount of small molecule gas usually escapes from the die head due to high temperature along with the wire during the extrusion process of the extruder, a negative pressure air hood is generally installed directly above the extruder head, and a special activated carbon absorption device is connected behind the negative pressure air hood to absorb small molecule gas to prevent small molecule gas from entering the surrounding environment and causing discomfort to the staff. At the same time, due to the cooling of the wire in water, a large amount of steam will evaporate upward from the head of the water tank. The steam will be absorbed upward by the negative pressure air hood together with the small molecules. In actual operation, the amount of water vapor in the gas absorbed by the negative pressure air hood is much greater than the amount of small molecule gas. A large amount of water vapor enters the pipeline, which will occupy the absorption capacity of the activated carbon absorption device connected behind the negative pressure device, causing the activated carbon absorption device to absorb a large amount of water and fail. By adding a condenser 8 to re-condense the water vapor and then introduce it into the tank body 2 by gravity, the water vapor in the negative pressure channel can be significantly reduced, thereby significantly improving the service life of the activated carbon absorption device.

[0026] The utility model is designed for cleaning drooling of an extruder. In actual use, since the drooling cooling tank is located below the end of the cooling water tank 1, the drooling cooling area is just directly below the head of the extruder. When the extruder is started or wire breakage occurs in the middle, the drooling will fall into the drooling cooling area and be cooled by the water flowing out from the cooling water tank 1 into the drooling cooling tank. After the drooling accumulates to a certain amount, the on-site personnel horizontally push the moving tank body 1, so that the buckling plate moves horizontally along the chute, changing the position where the drooling from the head continues to fall into the drooling cooling area, facilitating the on-site personnel to take out the accumulated drooling with tools. In this way, on the one hand, it avoids the drooling from falling to the ground and getting contaminated with dust, and can be pre-hardened, facilitating subsequent recycling. On the other hand, due to the relatively large bottom plate of the tank body, the drooling receiving position can be switched according to requirements, not only increasing the drooling capacity, but also enabling segmented treatment to avoid difficult handling due to excessive accumulation at one position. Moreover, the condenser 8 at the top can re-condense the evaporated water vapor back into the tank body 2 for circulation, significantly extending the service life of the activated carbon absorption device behind the negative pressure air hood. The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
