Description

Technical Field

[0001] The present invention relates to the technical field of metal product processing, and in particular to an intelligent plastic dipping device for metal products with an all-round plastic dipping function. Background Art

[0002] Dip molding, also known as hot dip molding or hot coating, is a common plastic coating process. It can be divided into liquid dip molding and powder dip molding according to the raw materials used in the dip molding. Dip molding products have been widely used in various aspects of production and life at home and abroad. Most of the liquid dip molding processes use thermoplastic dip molding liquid. Thermoplastic plastic coatings have the characteristics of preheating to soften and solidifying into films after cooling. It is mainly a physical melt plasticization film-forming process, and the processing and production are relatively simple.

[0003] When the existing plastic dipping device dips plastic into an iron chain, it is necessary to first remove the rust on the surface of the iron chain, and then hang the iron chain on a hook, and immerse the iron chain in the plastic dipping liquid through a lifting device to make the plastic dipping liquid adhere to the surface of the iron chain. However, the iron chain is composed of a plurality of rings. When the iron chain is immersed in the plastic dipping liquid in a vertical state, the rings are affected by gravity and the connection between the rings will fit together, resulting in the plastic dipping liquid not being easy to adhere to the surface of the iron chain. Summary of the invention

[0004] In order to overcome the disadvantage that an iron chain is composed of multiple rings and when the iron chain is in a vertical state and immersed in a plastic dipping liquid, the connection between the rings will fit together due to the influence of gravity, resulting in the plastic dipping liquid not easily adhering to the surface of the iron chain, the present invention provides an intelligent plastic dipping equipment for metal products with a full range of plastic dipping functions.

[0005] The technical solution is: an intelligent plastic dipping equipment for metal products with all-round plastic dipping function, including a connecting frame, a power unit, an electric gripper and a storage frame; the connecting frame is connected to several power units; each power unit is connected to an electric gripper, and the power unit is used to drive the iron chain to move; a storage frame is arranged under the connecting frame; it also includes a driving slide rail, a driving slider, a plastic dipping frame, a pump and a pipeline; each power unit is connected to a driving slide rail; each driving slide rail is slidably connected to a driving slider, and each driving slider is fixedly connected to the corresponding electric gripper; the connecting frame is fixedly connected to the plastic dipping frame; the storage frame is fixedly connected to the pump; the output end of the pump is fixedly connected and connected to a pipeline, and the pipeline is connected to the plastic dipping frame, and the input end of the pump is fixedly connected and connected to another pipeline, and the pipeline is connected to the inside of the storage frame.

[0006] As a further preferred solution, a hook is also included; the driving slide rail is slidably connected to another driving slider, and the driving slider is fixedly connected to the hook.

[0007] As a further preferred solution, the tip of the hook is provided with an extension portion, and during the dipping process, the extension portion is always higher than the liquid level of the dipping liquid.

[0008] As a further preferred solution, a liquid level detection head is also included; the liquid level detection head for detecting the liquid level height is fixedly connected to the right side of the plastic dipping frame.

[0009] As a further preferred solution, a straight rod is also included; a straight rod is slidably connected to the left side of each electric gripper.

[0010] As a further preferred solution, a rubber sleeve is provided on the surface of each straight rod.

[0011] As a further preferred scheme, it also includes round rods and electric push rods; each electric clamp is fixedly connected to an electric push rod on the left side, and each telescopic part of the electric push rod is fixedly connected to the corresponding straight rod; each electric clamp is fixedly connected to a plurality of round rods on the left side, and each electric clamp is provided with through holes of corresponding sizes to the straight rods and round rods on the right side.

[0012] As a further preferred solution, it also includes a motor and a support plate; a plurality of motors are fixedly connected to the left side of the plastic dipping frame; the rotating part of each motor is fixedly connected to a support plate, and a collection space is provided between the support plate and the bottom of the plastic dipping frame.

[0013] As a further preferred solution, the bottom of the plastic dipping frame is arranged in an inclined shape.

[0014] As a further preferred solution, a filter screen is also included; the filter screen for intercepting impurities is fixedly connected to the connection point between the plastic-impregnated frame and the pipeline.

[0015] The present invention has the following advantages: the present invention clamps one end of the iron chain through the electric clamp, and then controls the multi-stage push rod to push the corresponding driving slide rail to move slowly downward, so that the contact parts between the rings are staggered, so that the plastic dipping liquid can be fully adsorbed to the surface of each ring, and at the same time, the driving slider on the driving slide rail is controlled to synchronously drive the electric clamp and the hook to move to the rear side, so as to ensure that the plastic dipping liquid can be better adsorbed to the surface of each ring.

[0016] The present invention provides an extension portion at the tip of the hook, and during the dipping process, the extension portion is always higher than the liquid level of the dipping liquid. When the hook hooks the iron chain and puts the iron chain into the bottom of the dipping frame, the iron chain is restricted by the bottom of the dipping frame, so that the iron chain changes from an original drooping state to a straight state. When the iron chain is in a state close to being straight, if there is no restriction from the extension portion, the iron chain is easy to detach from the hook, resulting in the iron chain being unable to be hooked up normally.

[0017] The present invention arranges eight support plates, and places the support plates horizontally in the plastic dipping frame, so that when the iron chain is immersed in the plastic dipping frame, the iron chain will be plastic-dipped in the plastic dipping space formed by the support plate and the plastic dipping frame, so that impurities on the iron chain will fall onto the support plate, and when the plastic dipping of the iron chain is completed and leaves the plastic dipping frame, all motors are controlled to rotate 180 degrees clockwise from left to right, so that during the rotation of the support plate, impurities will fall downward along the surface of the support plate into the collection space, thereby avoiding the problem of impurities adhering to the surface of the next iron chain when it is dipped in plastic.

[0026] The power unit includes an electric guide rail 2, an electric slider 3 and a multi-stage push rod 4; the connecting frame 1 is bolted to the electric guide rail 2; the electric guide rail 2 is slidably connected to a plurality of electric sliders 3; each electric slider 3 is bolted to a multi-stage push rod 4, and each telescopic part of the multi-stage push rod 4 is bolted to the corresponding driving slide rail 7.

[0027] The driving slide rail 7 is slidably connected to another driving slider 8 , and the driving slider 8 is fixedly connected to the hook 9 .

[0028] An extension part 9a is provided at the tip of the hook 9, and during the dipping process, the extension part 9a is always higher than the liquid level of the dipping liquid. When the hook 9 hooks the iron chain and puts the iron chain into the bottom of the dipping frame 10, the iron chain is restricted by the bottom of the dipping frame 10, so that the iron chain will change from the original drooping state to a straight state. When the iron chain is in a state close to being straight, if there is no restriction of the extension part 9a, the iron chain will easily detach from the hook 9, resulting in the iron chain cannot be hooked up normally.

[0029] It also includes a liquid level detection head 101; the liquid level detection head 101 is bolted to the right side of the plastic dipping frame 10.

[0030] A straight rod 12 is also included; each electric clamp 5 is slidably connected to the left side with a straight rod 12 for catching the iron chain.

[0031] A rubber sleeve is provided on the surface of each straight rod 12 . By providing the rubber sleeve on the surface of the straight rod 12 , when the iron chain is hung on the straight rod 12 , the iron chain is prevented from slipping out of the straight rod 12 .

[0032] It also includes a round rod 13 and an electric push rod 14; each electric clamp 5 is bolted to an electric push rod 14 on the left side, and the telescopic part of each electric push rod 14 is fixedly connected to the corresponding straight rod 12; two round rods 13 are fixedly connected to the left side of each electric clamp 5, and a through hole corresponding to the size of the straight rod 12 and the round rod 13 is opened on the right side of each electric clamp 5.

[0033] Here is how the above example works:

[0034] First, a sufficient amount of plastic dipping liquid is poured into the storage frame 6, and the electric guide rail 2, the electric slider 3, the multi-stage push rod 4, the electric clamp 5, the drive slide rail 7, the drive slider 8, the pump 11 and the electric push rod 14 are connected to the power supply, and the input end of the pump 11 is connected to the storage frame 6. Then the operator takes out an iron chain that needs to be dipped in plastic. If it is a shorter iron chain, one end of the iron chain is placed upwards, and then the electric clamp 5 on the drive slide rail 7 is controlled to clamp one end of the iron chain. At the same time, a straight rod 12 is set on the left side of each electric clamp 5, so that the operator can first put the iron chain One end of the chain is hung on the straight rod 12, so that the operator does not need to hold the chain all the time, reducing the burden on the operator due to the heavy chain, and a rubber sleeve is arranged on the surface of the straight rod 12, so that when the chain is hung on the straight rod 12, it is prevented from sliding out of the straight rod 12. When the chain is hung on the straight rod 12, the chain is in a vertical drooping state, and the pump 11 is controlled to suck the plastic dipping liquid in the storage frame 6, and the plastic dipping liquid is pumped from the storage frame 6 to the plastic dipping frame 10 through the pipeline 18, and then the multi-stage push rod 4 is controlled to push the corresponding driving slide rail 7 to move slowly downward, so that the chain is immersed in the plastic dipping liquid. In the plastic dipping liquid in the frame 10, when the lowest ring of the iron chain contacts the bottom of the plastic dipping frame 10, the lowest ring is supported by the bottom of the plastic dipping frame 10, and counting from the bottom to the top, the ring at the second height continues to descend, and then is dislocated with the lowest ring, so that the contacting parts are staggered, so that the plastic dipping liquid can be fully adsorbed to the surface of each ring. At the same time, the driving slider 8 on the control driving slide rail 7 synchronously drives the electric clamp 5 and the hook 9 to move to the rear side, and the moving speed of the driving slider 8 is less than the pushing speed of the multi-stage push rod 4, so as to ensure that the plastic dipping liquid can be more It is well adsorbed to the surface of each ring. When the iron chain is completely fitted with the bottom of the plastic dipping frame 10, at this time, only half of the ring clamped by the electric clamp 5 is immersed in the plastic dipping liquid, and the other half is located above the plastic dipping liquid. It should be noted that the prior art only holds one end of the iron chain by a clamp so that the iron chain is immersed in the plastic dipping liquid in a vertical state, and the rings on the vertical iron chain are tightly fitted to each other. At this time, the plastic dipping liquid cannot enter the contact part between the rings. Therefore, through the above working process of the present invention, it can be seen that the present invention is superior to the prior art and makes the plastic dipping of the iron chain more complete.

[0035] When the length of the iron chain that needs to be dipped is much longer than the width in the dipping frame 10, at this time, the rightmost end of the iron chain is clamped by the electric clamp 5 located on the rightmost driving slide rail 7, and then the operator divides the iron chain into equal parts, and each equal division point closest to the dipping frame 10 is located above the dipping frame 10, and then the second equal division point from right to left is hooked on the hook 9 on the second driving slide rail 7, and then the third equal division point is hung on the hook 9 on the third driving slide rail 7, so that the iron chain is suspended in a wave shape, and then the three multi-stage push rods 4 are controlled to push the corresponding driving slide rails 7 to move slowly downward, so that the iron chain is immersed in the dipping liquid in the dipping frame 10, and when the lowest ring of the iron chain contacts the bottom of the dipping frame 10, the lowest ring is supported by the bottom of the dipping frame 10, and counting from the bottom to the top, the ring at the second height continues to descend, and then is dislocated with the lowest ring, so that the contacting parts are staggered, so that the dipping liquid can be fully absorbed Attached to the surface of each ring, at the same time, the driving slider 8 on the control driving slide rail 7 synchronously drives the electric clamp 5 and the hook 9 to move backward, and the moving speed of the driving slider 8 is less than the pushing speed of the multi-stage push rod 4, thereby ensuring that the plastic dipping liquid can be better adsorbed to the surface of each ring. When the iron chain is completely in contact with the bottom of the plastic dipping frame 10, at this time, only half of the ring clamped by the electric clamp 5 is immersed in the plastic dipping liquid, and the other half is located above the plastic dipping liquid, while the ring hooked by the hook 9 is completely immersed in the plastic dipping liquid, and the bottom of the hook 9 is in contact with the bottom of the plastic dipping frame 10. At the same time, when the iron chain is immersed in the plastic dipping frame 10, the liquid level of the plastic dipping liquid is detected by the liquid level detection head 101, so that the liquid level of the plastic dipping liquid is always flush with the upper part of the plastic dipping frame 10, avoiding the problem that the plastic dipping liquid is squeezed out of the plastic dipping frame 10 when the iron chain is immersed in the plastic dipping frame 10, and at the same time avoiding the problem that the liquid level is low when the plastic dipping liquid is adsorbed by the iron chain, affecting the plastic dipping effect of the iron chain.

[0036] In addition, the tip of the hook 9 is provided with an extension portion 9a, and during the dipping process, the extension portion 9a is always higher than the liquid level of the dipping liquid. When the hook 9 hooks the iron chain and puts the iron chain into the bottom of the dipping frame 10, the iron chain is restricted by the bottom of the dipping frame 10, so that the iron chain will change from the original drooping state to a straight state. When the iron chain is in a state close to being straight, if there is no restriction of the extension portion 9a, the iron chain is easy to detach from the hook 9, resulting in the iron chain cannot be hooked up normally.

[0037] In this way, after being spread out at the bottom of the plastic dipping frame 10, the iron chains are distributed in a wave shape, which can accommodate the iron chains to the maximum extent while not contacting each other. At the same time, since some iron chains are of different sizes, the electric clamp 5 cannot adapt well to iron chains of various sizes. Therefore, one end of the iron chain is first hung on the straight rod 12, and then the straight rod 12 is pulled upward by the electric push rod 14, so that the straight rod 12 drives one end of the iron chain to move upward synchronously, so that the upper part of the iron chain contacts the two round rods 13, and one end of the iron chain is initially clamped under the cooperation of the straight rod 12 and the two round rods 13, and then clamped by the electric clamp 5, which can adapt to iron chains of different sizes while improving the stability of the electric clamp 5 in clamping the iron chain. Example 2

[0038] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a motor 15 and a support plate 16; eight motors 15 are bolted to the left side of the plastic dipping frame 10; the rotating part of each motor 15 is fixedly connected to a support plate 16, and a collection space is set between the support plate 16 and the bottom of the plastic dipping frame 10.

[0039] The bottom of the plastic dipping frame 10 is arranged in an inclined shape. By arranging the bottom of the plastic dipping frame 10 in an inclined shape, all impurities are gathered in one corner, which is convenient for subsequent cleaning.

[0040] A filter screen 17 is also included; the filter screen 17 for intercepting impurities is fixedly connected to the connection point between the plastic dipping frame 10 and the pipeline 18.

[0041] Here is how the above example works:

[0042] When in use, the motor 15 is connected to the power supply. After a long period of plastic dipping, although the iron chain is first polished and then placed in the plastic dipping liquid for plastic dipping, a small amount of impurities will still remain on the surface of the iron chain. Therefore, after a long period of plastic dipping, a large amount of impurities will remain and accumulate in the plastic dipping frame 10, causing the plastic dipping liquid to be contaminated, affecting the plastic dipping quality of the iron chain. Therefore, by setting eight support plates 16, the support plates 16 are placed horizontally in the plastic dipping frame 10, so that when the iron chain is immersed in the plastic dipping frame 10, the iron chain will be plastic dipping in the plastic dipping space formed by the support plates 16 and the plastic dipping frame 10, so that the impurities on the iron chain will fall onto the support plates 16. When the plastic dipping of the iron chain is completed and it leaves the plastic dipping frame 10, all the motors 15 are controlled to rotate 180 degrees clockwise from left to right, so that the support plates 1 During the rotation of 6, impurities will fall downward along the surface of the support plate 16 into the collection space, avoiding the problem that impurities will adhere to the surface of the next iron chain when it is dipped in plastic; at the same time, the bottom surface of the plastic dipping frame 10 is set to be inclined, so that the impurities falling into the collection space will gather in a corner, which is convenient for subsequent cleaning; and when the motor 15 drives the support plate 16 to rotate, because there is a sufficient distance between the support plate 16 and the bottom of the plastic dipping frame 10, the impurities will not be moved to the top of the support plate 16 again during the rotation of the support plate 16. When the plastic dipping work is completed, the pump 11 is controlled to pump the plastic dipping liquid in the plastic dipping frame 10 back into the storage frame 6. When withdrawing, the impurities are intercepted by the filter screen 17 to prevent the impurities from being pumped into the storage frame 6, and then the impurities in the plastic dipping frame 10 are removed by the operator.

These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
