Description

Technical Field

[0001] This utility model relates to the field of chip conveyor technology, and in particular to a scraper-type chip conveyor with temperature control function. Background Technology

[0002] In the field of machining, scraper-type chip conveyors are widely used for collecting and conveying machine tool cutting chips. Traditional chip conveyors use chain plates to move the chips. They also utilize cutting fluid to cool and wash the chips before finally discharging them into a receiving device.

[0003] However, when machining high-strength metals or materials with poor thermal conductivity, the intense friction between the tool and the workpiece generates a large amount of heat, causing the chip temperature to rise sharply. Even after initial cooling with cutting fluid, the discharged chips may still maintain a high temperature. High-temperature chips accumulate in the chip conveyor or receiving device, and may cause a fire if they come into contact with flammable materials. In particular, blocky chips are large in size and have difficulty dissipating internal heat, which may damage equipment during subsequent crushing or recycling. When people come into contact with the chips, they are also prone to burns. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high chip temperature, low cooling efficiency, and safety hazards in the existing technology of machine tool processing, and to propose a scraper-type chip conveyor with temperature control function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scraper-type chip conveyor with temperature control function includes a housing, a transmission assembly, and a chip conveying chain. The housing is equipped with a spray assembly for cooling the chips on the chip conveying chain. A receiving trolley is located below the discharge port of the housing, and a quantitative temperature control assembly is installed inside the receiving trolley.

[0007] In some embodiments, the spray assembly includes a first water pump, a suction pipe, a drain pipe, and a nozzle. The first water pump is connected to the interior of the housing through the suction pipe and sprays the chip conveyor chain plate through the drain pipe and the nozzle.

[0008] In some embodiments, the quantitative temperature control component includes an outer frame, a support plate, and an electric push rod. The support plate achieves lifting and lowering movement through the electric push rod, controlling the opening and closing of the support plate to the outer frame. The top two sides of the support plate are provided with inclined surfaces for debris to slide off after cooling.

[0009] The transmission assembly drives the chip conveyor chain plate to operate intermittently, thereby achieving batch cooling of the chips.

[0010] In some embodiments, a water spray pipe and a second water pump are provided on one side of the receiving trolley, and a water collection pipe is provided on the other side of the receiving trolley. The water spray pipe is connected to the first liquid storage tank to circulate and cool the debris on the support plate.

[0011] In some embodiments, the water collection pipe is connected to the second liquid storage tank, and the drainage speed of the water collection pipe is less than the liquid inlet speed of the spray pipe, so that the high-temperature debris is completely immersed in the liquid for cooling.

[0012] In some embodiments, a temperature sensor is provided inside the outer frame to detect the temperature of the debris.

[0013] In some embodiments, a liquid storage tank is provided at the bottom of the housing, and the liquid storage tank is connected to the machine tool via a first circulating water pump.

[0014] In some embodiments, the cooling liquid pre-stored in the first storage tank is cutting fluid; the receiving trolley achieves liquid return through a first connecting pipe and a second connecting pipe of the storage tank.

[0015] In some embodiments, the cooling liquid pre-stored in the first storage tank is water, and the second storage tank is connected to the first storage tank through a connecting pipe to form a circulation of cooling water.

[0016] In some embodiments, the bottom of the receiving trolley is provided with a second filter screen and a drain pipe for separating debris and liquid.

[0017] Compared with the prior art, this utility model provides a scraper-type chip conveyor with temperature control function, which has the following beneficial effects.

[0018] 1. This utility model uses a spray assembly to initially cool the chips on the chip conveyor chain, and then uses an immersion-type quantitative temperature control assembly in the receiving trolley to perform secondary deep cooling on the blocky chips, forming a graded cooling process to ensure that chips of different shapes can reach a safe temperature.

[0019] 2. This utility model uses a temperature sensor to monitor the temperature of the debris in real time, and automatically unloads the material after the electric push rod reaches the set threshold. In addition, a second water pump automatically cools the debris on the support plate, which not only ensures the cooling effect but also reduces manual intervention.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0032] Example 1

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figure 1-3 A scraper-type chip conveyor with temperature control function includes a housing 1. The housing 1 is provided with a transmission component 101 and a chip conveying chain plate 2. The transmission component 101 is used to drive the chip conveying chain plate 2 to rotate cyclically.

[0035] The transmission assembly 101 includes a drive motor 1011, a drive gear 1012, and a driven gear 1013. The rotating end of the drive motor 1011 is connected to the drive gear 1012 via a gearbox. The drive gear 1012 is located at the top of the housing 1, and the driven gear 1013 is located at one end of the housing 1. Chip conveyor plates 2 are provided on the drive gear 1012 and the driven gear 1013. The drive gear 1012 is slidably connected to the housing 1. The housing 1 is provided with a tension adjustment assembly, which controls the tension of the chip conveyor plate 2 by adjusting the horizontal position of the drive gear 1011. A guide plate 1014 is provided inside the housing 1 to guide the movement path of the chip conveyor plate 2.

[0036] A liquid storage tank 3 is provided on one side of the bottom of the housing 1. A through hole 302 is provided on one side of the liquid storage tank 3. The liquid storage tank 3 is connected to the housing 1 through the through hole 302. The liquid storage tank 3 receives the cutting fluid in the housing 1 through the through hole 302. A first circulating water pump 301 is provided on the liquid storage tank 3. The drain end of the first circulating water pump 301 returns to the machine tool through a pipeline.

[0037] Below the discharge port of the housing 1 is a receiving trolley 4, which is used to receive the debris on the chip conveyor chain plate 2.

[0038] In use, the end of the housing 1 furthest from the receiving trolley 4 receives the chips and cutting fluid from the machine tool. The cutting fluid falls through the gap between the chip conveyor chain 2 and the housing 1 to the bottom of the chip conveyor chain 2. The chips are blocked on the chip conveyor chain 2. Under the drive of the transmission component 101, the chips on the chip conveyor chain 2 are moved towards the discharge port of the housing 1. After moving to the discharge port, the chips fall through the discharge port to the receiving trolley 4.

[0039] Meanwhile, the cutting fluid located in the housing 1 enters the storage tank 3 through the through hole 302, and is then transported back to the machine tool by the first circulating water pump 301, or stored in a storage tank for recycling. Example 2

[0040] Please see Figure 1-5 As shown, this embodiment is a further improvement on the above embodiment. In actual use, operators have found that even when the machine tool uses cutting fluid to cool the workpiece and chips during machining, when the material is a high-strength metal, the tool and workpiece experience intense friction, and the plastic deformation of the material generates a large amount of heat, causing the chip temperature to rise sharply. The cooling effect of the cutting fluid on the chips cannot meet expectations. When the chips are subsequently conveyed outwards via the chip conveyor chain 2, they remain at a high temperature. If flammable materials are present near the chip conveyor chain 2, this will increase the fire hazard. The following embodiment is provided to solve the above problems:

[0041] In order to control the temperature of the debris, a spray assembly is provided on the housing 1. The spray assembly is used to cool down the debris on the chip conveyor chain plate 2.

[0042] As one embodiment of the spray assembly, the spray assembly specifically includes a first water pump 102, which is fixedly connected to the housing 1. The bottom of the first water pump 102 is provided with a suction pipe 1021, and the end of the suction pipe 1021 away from the first water pump 102 is connected to the inside of the housing 1. The first water pump 102 is connected to a drain plate 1023 through a drain pipe 1022. The bottom of the drain plate 1023 is provided with a nozzle 1024. The first water pump 102 draws cutting fluid from the bottom of the housing 1 and sprays and cools the debris on the chip conveyor chain plate 2 through the drain pipe 1022, the drain plate 1023 and the nozzle 1024.

[0043] When in use, the first water pump 102 is started, and the cutting fluid in the housing 1 is absorbed through the suction pipe 1021. Then, the fluid is sprayed downward through the drain pipe 1022, the drain plate 1023 and the nozzle 1024 to cool down the high-temperature chips on the chip conveyor chain plate 2 that receive the processing machine tool. Multiple sets of spraying components can be set on the housing 1. The cooling efficiency of high-temperature chips is improved by multiple sets of spraying components, and the temperature of the chips falling into the receiving trolley 4 for recycling is controlled.

[0044] However, the chips produced by cutting and machining include thin, ribbon-like chips as well as larger, block-shaped chips. The chips have poor thermal conductivity; for example, ceramic chips dissipate heat slowly and remain at a high temperature for a considerable time after leaving the machine tool. While the thinner chips cool down quickly after being sprayed by the aforementioned spray system, some larger chips may still retain a significant amount of heat inside. During subsequent chip processing, this can significantly raise the temperature of subsequent processing equipment, affecting its normal operation and even causing damage. If the chips in the receiving trolley 4 are manually removed, contact with the heat-stored block-shaped chips can easily burn the operator.

[0045] For this, please refer to Figure 1-9 As shown, further improvements are made to the receiving trolley 4. Specifically, a quantitative temperature control component is added inside the receiving trolley 4. The quantitative temperature control component includes an outer frame 5, which is located on the top inner side of the receiving trolley 4. A support plate 501 is provided on the inner side of the outer frame 5. An electric push rod 502 is provided on the top of the support plate 501. A fixing plate 5021 is provided on the top of the electric push rod 502. The fixed end of the electric push rod 502 is fixedly connected to the fixing plate 5021, and the movable end of the electric push rod 502 is fixedly connected to the support plate 501. The fixing plate 5021 is fixedly connected to the receiving trolley 4.

[0046] A water spray pipe 503 is provided on one side of the receiving trolley 4. A second water pump 5031 is provided at the end of the water spray pipe 503 away from the receiving trolley 4. The water spray pipe 503 is fixedly connected to the outlet end of the second water pump 5031. A first liquid storage tank 5032 is provided at the inlet end of the second water pump 5031. The first liquid storage tank 5032 is provided with a liquid inlet.

[0047] A water collection pipe 504 is provided on the other side of the receiving trolley 4, and a second liquid storage tank 505 is provided at the end of the water collection pipe 504 away from the receiving trolley 4; the top two sides of the support plate 501 are provided with inclined surfaces from the inside out; the water collection pipe 504 is inclined, and the end of the water collection pipe 504 away from the receiving trolley 4 is inclined downward. A temperature sensor is provided on the inner side of the outer frame 5.

[0048] In use, the receiving trolley 4 directly receives the debris on the chip conveyor chain plate 2, or the receiving trolley 4 receives the debris after it has been sprayed by the spraying assembly.

[0049] The transmission assembly 101 drives the chip conveyor chain 2 to intermittently convey chips into the receiving trolley 4, causing high-temperature chips on the chip conveyor chain 2 to fall into the receiving trolley 4 in batches. When the high-temperature chips fall into the receiving trolley 4, they first fall onto the support plate 501. At the same time, the second water pump 5031 delivers cooling liquid from the first liquid storage tank 5032 to the top of the support plate 501 to cool the high-temperature chips above the support plate 501. It should be noted that the drainage speed of the water collection pipe 504 is less than the liquid inlet speed of the water spray pipe 503 to the top of the support plate 501, so that the cooling liquid can cover the top surface of the chips, immersing the high-temperature chips on the support plate 501 for cooling. The cooling liquid is also supplied from the inner side of the outer frame 5. The temperature sensor detects the temperature of the debris and the cooling liquid in real time. If the temperature is still at the preset high temperature threshold, the cooling liquid is supplied to the support plate 501. The liquid that has been heated is recovered to the second storage tank 505 through the water collection pipe 504. If the temperature sensor detects that the temperature inside the outer frame 5 is lower than the preset high temperature threshold, it indicates that the debris is completely in a low temperature state and the debris has been cooled. At this time, the second water pump 5031 is temporarily turned off, so that the liquid enters the second storage tank 505 through the water collection pipe 504. Then, the electric push rod 502 drives the support plate 501 to move downward, so that the debris on the support plate 501 falls into the receiving trolley 4 through the inclined surface of the support plate 501.

[0050] It should be added that a first filter screen is provided at the end of the water spray pipe 503 and the water collection pipe 504 that connects to the inner part of the outer frame 5 to prevent debris from entering. A discharge door is provided on the receiving trolley 4 for recovering the cooled debris; a second filter screen can be installed on the inner bottom of the receiving trolley 4 to separate debris from the liquid falling into the receiving trolley 4; and a drain pipe with a valve is provided on one side of the bottom of the receiving trolley 4 to discharge any residual liquid inside the receiving trolley 4. The cooling liquid for the debris during this process can be a non-cutting fluid coolant, and the coolant can be water; and a cooling pipe can be pre-installed in the second storage tank 505, which can be cooled by a compressor to maintain the low temperature of the coolant.

[0051] Furthermore, a first connecting pipe can be provided on the receiving trolley 4, and a second connecting pipe can be provided on the liquid storage tank 3. When the receiving trolley 4 receives debris, the first and second connecting pipes are sealed together by a flange. The first and second connecting pipes are used for the return flow of cutting fluid from the receiving trolley 4 to the liquid storage tank 3. When the temperature of the liquid on the support plate 501 is lower than the preset high temperature threshold, the support plate 501 is moved downward by the electric push rod 502, so that the debris and liquid fall through the gap between the support plate 501 and the outer frame 5. The height of the first and second connecting pipes is lower than that of the second filter screen. When the cooling liquid is returned through the first connecting pipe and the second connecting pipe, the cooling liquid for the debris is the cutting fluid. That is, the cooling liquid pre-stored in the first reservoir 5032 is the cutting fluid. The first reservoir 5032 is connected to the storage tank 3 through the suction pipe. The cutting fluid in the storage tank 3 is directly sucked into the first reservoir 5032 by the negative pressure generated by the second water pump 5031. Then, it is sprayed onto the high-temperature debris through the water spray pipe 503. Afterward, it is returned to the storage tank 3 through the first connecting pipe and the second connecting pipe.

[0052] As an optional or further solution, a connecting pipe is provided on the second reservoir 505. When the first reservoir 5032 is pre-filled with water, the second reservoir 505 is connected to the first reservoir 5032 through the connecting pipe, forming a circulation of cooling water. When the first reservoir 5032 is connected to the storage tank 3, similarly to the receiving trolley 4, the second reservoir 505 is connected to the storage tank 3 through the connecting pipe, allowing the cutting fluid in the receiving trolley 4 and the second reservoir 505 to flow back into the storage tank 3.
