Description

Technical Field

[0001] The invention relates to the technical field of automatic mixing of automobile repair paints, and in particular to a conveying device and a color mixing device. Background Art

[0002] When matching the color of car repair paint before painting, one of the common methods is to compare the color of the car with the color of the color card, find the color card of the same color, and find the masterbatch ratio and weight formula of each masterbatch according to the color card number from the color matching software database in the computer. According to the formula, the required multiple masterbatches are weighed, mixed, stirred and blended manually to produce car repair paint (hereinafter referred to as car paint) with the same color as the color card. However, the manual efficiency is low, and the car repair paint blended according to the color card usually has a certain deviation from the color of the car, which requires manual further adjustment, which is time-consuming and laborious, and has high technical requirements for color blenders. Experienced blenders are required to blend car paint with the same color.

[0003] In the existing technology, there is also a method of finding the formula of spraying paint at the time of leaving the factory according to the model or paint code of the car, or using an optical instrument (spectrophotometer) to measure the surface paint of the car, and obtaining the paint formula. This method of obtaining the formula can be suitable for the analysis of most car surface paints, which is more accurate and reduces the error between the color of the car paint obtained by the formula obtained according to the car model or paint code and the actual color of the car paint. But even so, the data previously statistically shown that a considerable proportion of car surface paints still have color differences after one color matching, and further manual color matching correction is still required. Therefore, the color matching of today's car repair paint has high requirements for labor and high dependence, while the efficiency of manual color matching is low, especially some paint shops have a very large amount of color matching per day, which can reach dozens or hundreds of kinds, and one color matcher cannot complete it. Some shops even need two or four color matchers. Even so, due to the high labor intensity, poor environment (colors are stuck everywhere, even on the body), and the need for long-term accumulation of technical improvement, people are still unwilling to do the job of color matching. On the other hand, it is also very difficult to recruit an excellent color matcher, and no one will do it if the salary is low. Nowadays, color matching technicians are necessary, but for paint shops with small amounts of color matching or color matching is just an auxiliary business (such as some 4S shops), the income from paint matching cannot even cover the salary of a painter. Therefore, if there is a low-cost equipment on the market that can automatically and accurately match the amount of masterbatches of each color, it can achieve the purpose of improving efficiency, reducing the requirements for matching technology, and reducing labor costs. Such equipment has a market.

[0004] In fact, in recent years, some companies have developed automatic color mixing machines for car repair paints, but they have not been able to form a stable product and put it on the market.

[0005] We all know that the mature and common methods for color matching of automotive paints in the world all use the weight ratio method, and the masterbatch is manually poured out from the paint bucket to weigh and color match. That is, according to the weight requirements of the required color matching masterbatch, the masterbatch is manually poured out from the masterbatch bucket equipped with a slurry cover on the upper part through the slurry outlet on the slurry cover. The weight of the required color matching masterbatch is weighed on an electronic scale. The color matching masterbatch in each formula is poured out from the masterbatch bucket and weighed to reach the required weight. The color matching masterbatch is stirred and mixed to complete the color matching of the required color paint. The slurry cover has a stirring function and a manual control masterbatch pouring function. At present, the color matching formulas of manufacturers of automotive repair paint color matching masterbatch in the world (such as: Xinjin, DuPont, PPG, BASF) are all designed according to the weight ratio.

[0006] There are two benefits to using weight ratio to manually pour paint and mix colors:

[0007] 1. It is convenient to pour out the required amount of masterbatch from the masterbatch barrel, and it is also convenient to control the pouring amount: just observe that when the required weight on the weighing scale is about to be reached, manually slow down the pouring speed of the masterbatch gradually, so that it slowly approaches the required pouring weight, until it finally reaches the required masterbatch weight and stops pouring the masterbatch. Other color matching masterbatches can also be poured out and weighed in the same way;

[0008] 2. Pour several masterbatches that need to be matched into a container and stir them evenly: For example, if three masterbatches are needed to match one color, the weight of each masterbatch is 1.1 grams for masterbatch A, 2.2 grams for masterbatch B, and 3.3 grams for masterbatch C. Put an empty bucket on the electronic scale and reset the weight. Pour masterbatch A into the empty bucket until the electronic scale shows 1.1 grams; reset the electronic scale, then pour masterbatch B until the electronic scale shows 2.2 grams; reset the electronic scale again, pour color paste C until the electronic scale shows 3.3 grams. Finally, stir the three masterbatches evenly with a stirring ruler to complete the color matching.

[0009] Using weight to match colors is the first natural choice in the history of color matching. In order to avoid color matching based on experience, the ratio of color masterbatches cannot be accurately known and the required amount of masterbatches cannot be accurately controlled. Based on experience, the most convenient weight ratio method for accurate color matching was developed.

[0010] In theory, it is also valid to use volume ratio color matching. However, the volume ratio color matching method that is valid in theory is difficult to implement in practice. The main reason is that the paint residue at the paint outlet of the metering device for the volume of the repair paint will affect the actual amount injected into the vessel, thereby causing a deviation in the actual amount of the repair paint obtained. For example, there are several ways to obtain the required volume of the color masterbatch by the volume ratio color matching method: Assumption 1: Pour the masterbatch manually into the measuring cup, and control the amount of the masterbatch poured according to the position of the volume scale scale of the measuring cup. But there is a problem with this. Due to the characteristics of the paint, the human eye observes the position of the measuring cup scale to determine the volume of the masterbatch, which cannot reach the required 0.1 gram weight accuracy. In particular, when a large amount of paint is mixed, the volume of the measuring cup must be large, and the cross-sectional area of ​​the measuring cup is larger. The error of the human eye in determining whether the masterbatch reaches the specified scale position is larger, and the color matching accuracy requirement of 0.1 gram cannot be met at all. Moreover, the inaccurate volume manual color mixing method is much more difficult and cumbersome in actual operation than the weight ratio color mixing method, so it cannot achieve effective color mixing and matching; Concept 2: Using the specific gravity cup method: Because of the wall residue of the masterbatch and the discontinuity of volume measurement, it is also difficult to obtain the required volume in actual application; Concept 3: Manual syringe volumetric measurement and injection method: Due to the masterbatch hanging tape at the injection tube head for extracting the masterbatch, it will cause accuracy errors. Removing the hanging tape is both troublesome and environmentally unfriendly. If it is not cleaned, it will flow to the outlet of the syringe head and affect the error guarantee below 0.1 gram. Similarly, manually injecting viscous masterbatch requires a lot of effort, and people with less strength cannot even push it. Although reducing the diameter of the syringe can reduce the injection force and improve the accuracy of a single injection, accurate injection of large amounts of masterbatch requires multiple extractions into the masterbatch container. Each extraction requires clearing the masterbatch hanging at the injection tube mouth, and increasing the number of extractions will increase the cumulative error. At this time, an error of 0.1 gram is more difficult to control, and this is much more complicated than the currently used weight ratio method for color matching. The color matching industry will of course choose the simple and easy-to-implement weight ratio method for color matching, rather than the volume ratio method for color matching, which is both troublesome and difficult to ensure accuracy.

[0011] After the weight ratio color matching method appeared, the technicians in this industry no longer considered using volume ratio to achieve color matching. Because from the past to the present, after analyzing the above-mentioned influencing factors, the industry personnel determined that it could not replace the weight ratio color matching and color matching, which has been subtly ingrained in the minds of the industry personnel and has become a technical prejudice.

[0012] In recent years, our company has broken the technical prejudice of the industry and developed a reflux pump valve structure, so that there is basically no paint residue and dryness on the paint nozzle after the car repair paint is poured out, so that the amount of repair paint pumped out by the car repair paint volume pump can be injected into the collection container, realizing the real automatic color matching of car repair paint, and researching and developing a volumetric measurement of car repair paint automatic color matching equipment. The rack of the color matching machine is equipped with multiple masterbatch barrel installation stations. The layout of the masterbatch barrel on the rack is generally divided into two types. One is to arrange it in a divergent shape along the radius with the rotating shaft as the center, such as CN201821510123.X, and the second is to arrange it in a rectangular shape, such as 201821510138.6. Both devices have been well received and recognized by large users. However, these two masterbatch barrel layouts must be combined with complex motion mechanisms to complete the action of receiving materials. Therefore, the equipment cost is increased, and because of its large size and wide space, it is not suitable for some small and medium-sized stores to purchase and use. In addition, when the masterbatch barrel needs to be loaded and unloaded on the rack, it is necessary to move the masterbatch barrel to the assembly position and stop it, and then use a special disassembly and assembly mechanism to disassemble and assemble the masterbatch barrel, which has low loading and unloading efficiency. Small and medium-sized stores need a semi-automatic color mixing device for automobile repair paint with a simple structure, high efficiency, accurate mixing, low cost, and the ability to reduce the operator's labor cost and operating technology to solve the above problems.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figures 1 to 6 As shown, an embodiment of the present invention provides a conveying device, which includes a first guide rail 10, a clamping module 20 and a limiting structure 30. The clamping module 20 can be movably arranged on the first guide rail 10 along the first guide rail 10. The clamping module 20 includes a base 21 and a clamping assembly 22 with adjustable relative positions. The clamping assembly 22 is arranged on the base 21. There is a gap between the clamping assembly 22 and the base 21. The limiting structure 30 is used to adjust the gap between the clamping assembly 22 and the base 21, and the gap is used to accommodate the clamped portion of the clamped member. In this embodiment, the clamping module 20 has a relatively arranged state to be assembled and a clamping state. When the clamping module 20 is in the state to be assembled, the gap becomes larger to loosen the clamped member. When the clamping module 20 is in the clamping state, the gap becomes smaller to clamp the clamped member. Specifically, the first guide rail 10 includes a first section 11 and a second section 12 that are connected to each other. When the clamping module 20 moves from the first section 11 to the second section 12, the state of the clamping module 20 is switched by the limiting structure 30. When the clamping module 20 is located in the first section 11, the clamping module 20 is in a state to be assembled. When the clamping module 20 is located in the second section 12, the clamping module 20 is in a clamping state.

[0051] By applying the conveying device provided in this embodiment, a limiting structure 30 is set, and the limiting structure 30 is used to adjust the interval between the clamping assembly 22 and the base 21. During the process of the clamping module 20 moving from the first section 11 to the second section 12, the state of the clamping module 20 can be switched through the limiting structure 30, so as to facilitate the disassembly and assembly of the clamped parts. There is no need to wait for the clamped parts to move to the assembly position and stop before using a dedicated disassembly and assembly mechanism for disassembly and assembly, which can improve the disassembly and assembly efficiency.

[0052] The limiting structure only needs to be able to switch the state of the pressing module 20 when the pressing module 20 moves from the first section 11 to the second section 12 .

[0053] like Figure 5 and Figure 6As shown, the limiting structure 30 includes a second guide rail 31 and a limiting member 32. The first guide rail 10 and the second guide rail 31 are arranged in the same direction, and the clamping module 20 can slide along the extension direction of the first guide rail and the second guide rail. Among them, a first slide groove 311 is arranged on the second guide rail 31, and the limiting member 32 is arranged in the first slide groove 311. The base 21 is arranged on the first guide rail 10. The limiting member 32 is connected to the clamping assembly 22, and the limiting member 32 cooperates with the first slide groove 311 to adjust the interval between the clamping assembly 22 and the base 21. In the process of the clamping module sliding relative to the first guide rail and the second guide rail, the limiting member 32 will move in the first slide groove 311. By adjusting the position of the limiting member in the first slide groove to adjust the position of the limiting member relative to the base 21 in the height direction, the interval between the clamping assembly 22 and the base 21 can be adjusted.

[0054] In this embodiment, the first guide rail 10 and the second guide rail 31 are arranged side by side, and the clamping module 20 can slide along the extension direction of the first guide rail and the second guide rail, so that the footprint of the device can be reduced and the integration of the device can be improved. In other embodiments, the first guide rail 10 and the second guide rail 31 can be arranged in series on a line, but with this arrangement, the length of the device will become larger.

[0055] In this embodiment, the first slide groove 311 is arranged on the side wall of the second guide rail 31, and the height of the first slide groove 311 relative to the first section 11 is higher than the height of the first slide groove 311 relative to the second section 12. In the process of the clamping module sliding relative to the first guide rail and the second guide rail, since the height of the first slide groove 311 relative to the first section 11 is higher than the height of the first slide groove 311 relative to the second section 12, and the stopper is arranged on the clamping assembly, when the clamping module 20 is located in the first section 11, under the support of the stopper, the interval between the clamping assembly 22 and the base 21 will increase, and the clamping module 20 is in a state to be assembled. When the clamping module 20 is located in the second section 12, under the pulling action of the stopper, the interval between the clamping assembly 22 and the base 21 will decrease, and the clamping module 20 is in a clamping state. In this embodiment, the stopper is a bearing, so that the friction force of the stopper when sliding in the first slide groove can be reduced.

[0056] In other embodiments, the first slide groove can be set on the top wall of the second guide rail. By adjusting the groove depth of the first slide groove, it is also possible to adjust the distance between the clamping assembly 22 and the base 21 by using the limit member and the first slide groove in cooperation with each other during the sliding of the clamping module relative to the first guide rail and the second guide rail.

[0057] like Figure 3 and Figure 4As shown, the clamping assembly 22 includes a first clamping member 221, a connecting member 222 and a second clamping member 223, the first clamping member 221 is located on one side of the base 21, the second clamping member 223 is located on the other side of the base 21, the connecting member 222 is arranged on the base 21, one end of the connecting member 222 is connected to the first clamping member 221, and the other end of the connecting member 222 is connected to the second clamping member 223. In this embodiment, a through hole is provided on the base 21, the connecting member 222 is arranged in the through hole, and there is a gap between the outer wall of the connecting member 222 and the inner wall of the through hole, and the connecting member is not connected to the inner wall of the through hole. Among them, there is a gap between the first clamping member 221 and the base 21, and the gap is used to accommodate the clamped part of the clamped member, and the limiter 32 is arranged on the second clamping member 223. In the process of the clamping module sliding relative to the first guide rail and the second guide rail, as the height of the first slide groove changes, the second clamping member will use the connecting member to drive the first clamping member to move relative to the base. Specifically, when the clamping module 20 is located in the first section 11, under the support of the second clamping member and the connecting member, the first clamping member 221 will move in the direction away from the base 21, and the interval between the clamping assembly 22 and the base 21 will become larger. At this time, the clamping module 20 is in a state to be assembled. When the clamping module 20 is located in the second section 12, under the pulling action of the second clamping member and the connecting member, the first clamping member 221 will move in the direction close to the base 21, and the interval between the clamping assembly 22 and the base 21 will become smaller. At this time, the clamping module 20 is in a clamped state.

[0058] In order to improve the application range of the conveying device, an adjustment structure 23 is provided between the first pressing member 221 and the connecting member 222, and the adjustment structure 23 is used to adjust the maximum distance between the first pressing member 221 and the base 21. By adjusting the maximum distance between the first pressing member and the base, the distance can be suitable for clamped parts of different sizes.

[0059] like Figure 5 As shown, the adjustment structure 23 includes a waist-shaped hole 231, a fixing member 232 and an adjustment member 233. The waist-shaped hole 231 is arranged on the connecting member 222, and the fixing member 232 passes through the waist-shaped hole 231 and is connected to the first clamping member 221. Among them, the waist-shaped hole 231 extends along the length direction of the connecting member 222, and the waist-shaped hole 231 can provide a moving space for the fixing member 232. Specifically, the connecting member 222 has a mounting hole, and the extension direction of the mounting hole is the same as the extension direction of the connecting member 222. By inserting the adjustment member 233 into the mounting hole and making the end of the adjustment member 233 abut against the fixing member 232, the relative position of the fixing member 232 in the waist-shaped hole 231 can be limited, and then the maximum distance between the first clamping member and the base can be limited. In this embodiment, the fixing member 232 and the adjustment member 233 are both bolts, which have the advantages of simple structure, easy maintenance and low cost.

The guide wheel can be divided into a driving wheel and a driven wheel according to the power source.

[0071] Among them, the function of the first driving part 60 is to move the clamping module 20 from the assembly position to the liquid outlet position according to the program in the control mechanism and certain working conditions and procedures. Therefore, the first driving part 60 can also be a linear motion cylinder or an oil cylinder assembly, which is connected to the clamping module 20 through a cylinder rod, and the clamping module 20 is driven to move on the first guide rail 10 by the cylinder rod.

[0072] like Figure 7 , Fig.15 as well as Fig.16 As shown, in order to provide a better working environment for the paint mixing personnel, the color mixing device also includes a shell 70, and the shell 70 is covered on the platform 40. The shell can improve the protection performance of the device. The shell 70 has an operating door 71 set at a corresponding assembly position, and the operating door 71 has an open state and a closed state set relative to the shell 70. A door opening and closing state sensor is set in the operating door 71, and the sensor is connected to the control mechanism. The control mechanism judges the opening and closing state of the door by judging the electrical signal of the sensor, and then controls the working process of other electrical appliances.

[0073] The color adjusting device further includes a second driving unit 81, a rotating shaft 82 and a connecting rod mechanism 83. Specifically, the second driving unit 81 is movably disposed on the housing 70, the rotating shaft 82 is rotatably disposed on the housing 70, the rotating shaft 82 is drivingly connected to the operating door 71, one end of the connecting rod mechanism 83 is hinged to the second driving unit 81, and the other end of the connecting rod mechanism 83 is connected to the rotating shaft 82.

[0074] like Fig.15As shown, the link mechanism 83 includes a first link 831 and a second link 832 that are hinged to each other, one end of the first link 831 is hinged to the pusher 812 of the second driving part 81, and one end of the second link 832 is fixedly connected to the rotating shaft 82. When the pusher 812 of the second driving part 81 moves relative to the housing, the pusher 812 can drive the second link to rotate through the first link, and then use the second link to drive the rotating shaft to rotate.

[0075] In this embodiment, the color adjustment device further includes a third connecting rod 84, a first slide rail 85 and a first slider 86. Among them, one end of the third connecting rod 84 is fixedly connected to the rotating shaft 82, the other end of the third connecting rod 84 is hinged to the operating door 71, and the rotating shaft is drivingly connected to the operating door through the third connecting rod. By setting the first slide rail 85 on the housing 70, the first slider 86 is slidably set on the first slide rail 85. Since the first slider 86 is hinged to the operating door 71, during the movement of the operating door 71, the first slider 86 and the first slide rail 85 cooperate to limit the movement of the operating door 71 along the preset path, which can improve the stability of the operating door when moving.

[0076] like Fig.15 As shown, in this embodiment, the second driving part 81 includes a driving member, a second slide rail 811 and a pushing member 812, the driving member and the second slide rail are both arranged on the housing, and the pushing member is slidably arranged on the second slide rail. Specifically, the pushing member is hinged to the connecting rod mechanism. Among them, the second slide rail is perpendicular to the first slide rail. In this embodiment, the pushing member 812 is a slider. In other embodiments, the second driving part can be replaced by a linear driving mechanism such as a cylinder, a hydraulic cylinder, a rack, etc., as long as the second driving part can be used to drive the connecting rod mechanism to move.

[0078] like Figure 7 , Figure 8 , Fig.12 , Fig.17 as well as Fig.18As shown, the color mixing device also includes a pumping mechanism 90 and a third driving unit 100. The pumping mechanism 90 is connected to the masterbatch barrel 51. The pumping mechanism 90 is used to pump out the oil in the masterbatch barrel 51. The third driving unit 100 is arranged on one side of the platform 40. The third driving unit 100 is drivingly connected to the pumping mechanism 90. The third driving unit 100 is used to drive the pumping mechanism 90 to operate. Among them, the platform 40 has a liquid outlet window 41, and the liquid outlet window 41 is arranged corresponding to the liquid outlet position. The oil pumped out of the masterbatch barrel 51 can flow into the receiving device 120 through the liquid outlet window. In this embodiment, a hole is arranged at the liquid outlet position, and the hole forms the liquid outlet window 41. The position of the receiving device 120 is below the hole. The masterbatch discharged each time enters the receiving device 120 below through the hole.

[0079] In this embodiment, the third driving unit 100 is located at the front side of the tail of the first guide rail 10. The third driving unit 100 includes a frame, a valve motor is arranged on the frame, a lever 101 is arranged on the valve motor, and the lever and the valve body lever are located on the same horizontal plane. When the masterbatch barrel 51 is located at the liquid discharge position, the valve motor drives the lever to rotate from a vertical state to a horizontal state, and the lever is combined with the valve body lever. The lever continues to rotate to rotate the valve body lever, thereby controlling the connection or closure of the slurry outlet.

[0080] Among them, a linear drive mechanism 102 is also arranged on the frame, and a rod head baffle 103 that moves up and down is arranged on the linear drive mechanism. When the masterbatch barrel 51 moves to the liquid outlet position, the rod head baffle just catches the pull plate at the top of the volume metering pump, and the rod head baffle drives the piston rod of the volume metering pump to move up and down. The linear drive mechanism is a screw nut mechanism (a linear motion unit such as a cylinder, as long as it can complete the linear motion in a controllable manner). A screw driven by a stepper motor is arranged on the frame, a nut is arranged on the screw, and the nut is connected to the rod head baffle, and the rod head baffle includes a groove structure. When the masterbatch barrel 51 moves, the piston head of the volume metering pump leaves or enters the groove located in the groove mechanism, and the nut moves up and down to make the piston rod move up and down, thereby sucking away and beating the masterbatch from the masterbatch barrel 51.

[0081] In this embodiment, the masterbatch barrel 51 is connected to the volumetric metering pump through the valve body, a barrel cover is provided on the masterbatch barrel 51, a pouring port is provided on the barrel cover, a pouring port cover is provided on the pouring port, the pouring port cover is slidably provided on the pouring port, the pouring port cover is connected to the buckle ring, a compression spring is provided between the buckle ring and the barrel cover to keep the pouring port cover in a closed state, a connecting piece is provided between the upper part of the masterbatch barrel 51 and the volumetric metering pump so that the volumetric metering pump forms a handle of the masterbatch barrel 51, the buckle ring is located on the side of the barrel cover close to the volumetric metering pump, and a stirring device is provided in the masterbatch barrel 51. For the specific structure of the masterbatch barrel 51, please refer to patent CN209061071U.

[0082] like Figure 8As shown, in order for the control mechanism to determine the positions of the clamping module 20 and the masterbatch barrel 51, and coordinate the working order and working duration of each electrical appliance in the control device, an assembly position sensor 111, a liquid outlet position sensor 112 and a barrel detection sensor 113 are installed on the platform 40. The assembly position sensor and the liquid outlet position sensor are respectively located at the two ends of the first guide rail 10, and the barrel detection sensor is located between the above two sensors, and the barrel detection sensor is closer to the assembly position sensor. The above sensors are electrically connected to the control mechanism, respectively. The assembly position sensor is used to test whether the clamping module 20 is located at the assembly position, the liquid outlet position sensor is used to test whether the clamping module 20 is located at the liquid outlet position, and the barrel detection sensor is used to detect whether the test masterbatch barrel 51 is installed in place in the clamping module 20. In this embodiment, the barrel detection sensor is a micro switch, and a bracket is provided between the sensor and the platform 40. In other embodiments, the bracket may not be provided, and the bracket is only installed to achieve the function.

[0083] In this embodiment, the color mixing device is provided with a code scanning device, which is arranged on the frame to facilitate the identification of the label on the masterbatch barrel 51. (The code scanning device can also be arranged at other positions, and the purpose of the code scanning device is to allow the control mechanism to determine whether the masterbatch barrel 51 is the masterbatch barrel 51 required in the program). By identifying whether the masterbatch barrel 51 loaded into the device is the required masterbatch barrel 51, the control mechanism coordinates the next step.

[0084] In this embodiment, a cleaning box is provided on the platform 40, and a brush assembly is provided in the cleaning box. The brush assembly includes a brush shaft and a brush. The brush shaft is a passive shaft. The cleaning box is located between the pulp outlet and the liquid outlet position, and is a necessary place for the masterbatch barrel 51. When an injection process is completed, the first driving unit 60 drives the masterbatch barrel 51 on the clamping module 20 to move from the liquid outlet position to the assembly position, and the pulp outlet will contact the brush, and the brush cleans the pulp outlet to prevent the residual color paste from drying. (Of course, the brush shaft can also be set as a driving wheel driven by a power source. This design method will improve the cleaning effect and increase the design difficulty and manufacturing cost).

[0085] In this embodiment, the frame is also provided with a movable drip box located above the liquid outlet position and below the slurry outlet nozzle, and the drip box includes a drip receiving station located directly below the slurry outlet nozzle and an avoidance station avoiding the slurry outlet nozzle. A linear motion mechanism is provided on the frame, such as a motor driving a gear, the rotation of the gear drives the rack to move, and the drip box and the rack are connected and move together. Or a cylinder is provided on the frame, and the cylinder piston rod drives the drip box to move together. After the injection channel is closed, that is, after the slurry outlet nozzle no longer discharges slurry, there may be residual color paste. A drip box is provided, and after the injection channel is closed, the drip box moves to directly below the slurry outlet nozzle to prevent residual color paste from dripping into the receiving device and affecting the accuracy.

[0086] In this embodiment, the color adjusting device also includes an active bevel gear arranged on the top of the device, and the active bevel gear is driven by a power source, which is a motor. A stirring device is arranged in the masterbatch barrel 51, and a bevel gear is arranged on the top of the stirring device. The bevel gear extends above the barrel cover, and the active bevel gear is meshed with the bevel gear on the masterbatch barrel 51 to drive the stirring device to rotate.

[0087] Specifically, one end of the stirring device is a stirring shaft extending into the masterbatch barrel 51, and a stirring blade is arranged on the stirring shaft. One end of the stirring device located outside the masterbatch barrel 51 is connected to a bevel gear, and the bevel gear is located above the barrel cover. When the masterbatch barrel 51 is located at the liquid discharge position, the active bevel gear and the bevel gear are meshed with each other in space, and the stirring device is driven to rotate and stir in the masterbatch barrel 51 through the motor and the gear mechanism. The stirring blade is a spiral stirring blade, which is a bubble-cutting blade. During the stirring process, the masterbatch slurry can be hit against the barrel wall to knock out or break the bubbles, which is convenient for volume measurement.

[0088] The working process of the color mixing device is as follows: the masterbatches in the formula are fed one by one, and one masterbatch barrel 51 is placed in the device at a time. After one masterbatch is fed, another masterbatch barrel 51 is placed on the device for feeding, and the above steps are repeated. After the required masterbatches are fed in sequence, they are manually stirred in the color mixing barrel (receiving device) to obtain the required color of automobile paint. The specific actions of the color mixing device are as follows:

[0089] (1) Initialization action of power on: the door in the operating door 71 is closed, and after the clamping module 20 moves to the assembly position of the first guide rail 10, the assembly position sensor transmits the position information of the clamping module 20 to the control mechanism, and then the control mechanism controls the door in the operating door 71 to open, and all motors inside the device are powered off;

[0090] (2) According to the needs of the prepared automotive paint, the masterbatch barrels 51 containing different masterbatches need to be installed on the pressing module 20 in sequence. The masterbatch barrels 51 are manually installed on the pressing module 20. When the ears at the bottom of the masterbatch barrel 51 are installed on the clamping structure of the pressing module 20 (the gap between the first pressing block and the base), the barrel detection sensor is used to detect whether the masterbatch barrel 51 is installed in place. When the masterbatch barrel 51 is installed in place, the control mechanism controls the operating door 71 to close. After the door is closed, the internal interlocking switch on the door and the door frame is closed, and all motors in the device are powered on.

[0091] (3) The masterbatch barrel 51 starts to move toward the liquid outlet position along the first guide rail. When the liquid outlet position sensor detects that the clamping module 20 has moved to the liquid outlet position, at this position, the piston head enters the groove of the groove-type mechanism. At the same time, the code scanning device scans the masterbatch barrel 51 and determines that the masterbatch barrel 51 is the pigment in the formula and is not repeated with the color previously injected in the formula. Then the third drive unit 100 moves, and the valve motor drives the lever to move. The lever is combined with the valve body lever. The lever rotates to rotate the valve body lever, so that the slurry outlet is connected and the material is discharged. If the information obtained by scanning the code does not match the correct information of the program, the control mechanism reports an error, and the masterbatch barrel 51 moves back to the origin and waits for error correction.

[0092] (4) When the amount of masterbatch discharged reaches the required amount, the control mechanism drives the valve motor to reverse, and the valve motor drives the lever to move in the opposite direction. The lever rotates to cause the valve body lever to rotate in the opposite direction, thereby controlling the slurry outlet to close;

[0093] (5) After the slurry nozzle is closed, the drip box moves from the avoidance station to the drip receiving station under the drive of the linear motion mechanism. The drip box is set. After the injection channel is closed, the drip box moves to the bottom of the slurry nozzle to prevent the residual color paste from dripping into the receiving device and affecting the accuracy.

[0094] (6) After the drip box enters the drip station, the pressing module 20 moves to the assembly position of the first guide rail 10 under the traction of the first driving unit 60. During the movement, the slurry outlet of the pressing module 20 passes through the cleaning box, and the slurry outlet of the masterbatch barrel 51 contacts and rubs with the brush. The brush cleans the slurry outlet to prevent the residual color paste from drying up.

[0095] (7) Finally, the pressing module 20 returns to the assembly position, the motor in the device is powered off, the operating door 71 is opened, and the staff takes out the masterbatch barrel 51 and puts in the next masterbatch barrel 51 according to the program prompt, and repeats the above working process. When all the masterbatch barrels 51 are unloaded, the masterbatch in the color mixing barrel is stirred to obtain the required automotive paint.

[0096] The device provided by this embodiment has the following beneficial effects:

[0097] (1) The state of the pressing module 20 is switched by the limiting structure 30, so that the masterbatch barrel 51 can be easily disassembled and assembled. There is no need to wait for the masterbatch barrel 51 to move to the assembly position and stop before using a dedicated disassembly and assembly mechanism to disassemble and assemble, which can improve the disassembly and assembly efficiency.

[0098] (2) The masterbatch barrel 51 uses volumetric measurement, including a volumetric metering pump connected to the masterbatch barrel 51 to achieve fixed volume injection of the color paste, which can automatically inject the color paste. The method of volumetric injection and volumetric color matching effectively reduces costs.

[0099] (3) The single masterbatch barrel 51 is used to move linearly on the first guide rail 10, which simplifies the device structure, reduces equipment costs, and greatly reduces the size of the device. It is more suitable for use in small and medium-sized stores commercially, and therefore has a good market prospect.
