Description

Technical Field

[0001] The invention relates to the field of coating processing, in particular to a mixing device and a mixing method for crack-resistant hot-melt road marking coating. Background Art

[0002] Crack-resistant hot-melt road marking paint is a high-performance road marking material, which is mainly used to improve the durability and crack resistance of road markings, ensuring that the markings maintain good visual effects and safety performance under various environmental conditions.

[0003] When mixing paint, if the volume of the mixing container is too large and the paint itself has a certain viscosity, it will be difficult for the paint to flow and mix in all directions inside the container when the paint is stirred using a horizontal stirring roller, resulting in uneven stirring of the paint and affecting the quality of the paint. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a crack-resistant hot-melt road marking paint mixing device and mixing method.

[0005] In a first aspect, the present invention provides a crack-resistant hot-melt road marking paint mixing device, comprising a mixing cylinder, a cylinder cover is installed on the top of the mixing cylinder, and further comprising:

[0006] Rotating the base to rotate the bottom installed inside the mixing cylinder;

[0007] An installation box is rotatably installed on the top of the mixing barrel and is connected to the rotating base via a plurality of connecting frames;

[0008] An inclined stirring device is installed between the rotating base and the installation box, and stirs the raw materials vertically and horizontally inside the mixing barrel simultaneously by setting an inclined stirring direction;

[0009] A feeding assembly, installed between the barrel cover and the installation box, for feeding raw materials into the interior of the mixing barrel;

[0010] A control unit installed inside the installation box, used to control the stirring speed of the inclined stirring device, so as to slow down the stirring speed of the inclined stirring device when the feeding assembly is feeding;

[0011] The staff controls the feeding component to feed the materials through the control unit. First, the feeding component is controlled to feed half of the capacity of the mixing drum. Then, the control unit controls the inclined stirring device to start. Since the stirring of the inclined stirring device is stirring in an inclined direction, the stirring of the inclined stirring device can be divided into two stirrings in the horizontal direction and the vertical direction, thereby driving the coating raw materials entering the mixing drum to flow vertically and horizontally, which is conducive to making the coating raw materials flow in all directions inside the mixing drum, thereby facilitating the uniformity of the stirring of the raw materials.

[0012] By first injecting half of the raw material into the mixing drum, the inclined stirring device reduces the resistance of the raw material to the inclined stirring device when stirring the raw material, which is conducive to repeated mixing of a small amount of raw material uniformly, and then the control unit controls the feeding assembly to continue injecting the raw material into the mixing drum, so that when the original raw material in the mixing drum has been mixed uniformly, it is conducive to improving the efficiency of mixing the raw materials uniformly;

[0013] In summary, by setting up the inclined stirring device, the mixing efficiency and mixing uniformity of the raw materials can be improved, thereby improving the quality of the raw material mixing.

[0014] Preferably, the inclined stirring device comprises:

[0015] A rotating shaft, rotatably mounted between the rotating base and the mounting box, the rotating shaft being arranged in an inclined manner;

[0016] A plurality of stirring rods are fixedly mounted in a circular array at the middle of the rotating shaft for stirring the raw materials, and the stirring rods are in a twisted shape;

[0017] A fixing plate, which is detachably fixed on the top of the installation box;

[0018] A first motor is fixed to the top of the fixing plate, and an output shaft of the first motor passes through the fixing plate and is fixed with a first gear;

[0019] A second gear is rotatably mounted on the mounting box and is coaxially fixedly connected to the rotating shaft, and the second gear is meshed with the first gear;

[0020] After the first motor is started, the output shaft drives the first gear connected to it to rotate. After the first gear rotates, it drives the second gear meshing with it to rotate. The second gear drives the rotating shaft to rotate. The rotating shaft drives the stirring rod to rotate, so that the stirring rod mixes the raw materials inside the mixing barrel. The stirring rod is in a twisted shape, so that the stirring rod can drive the raw materials in all directions, which is beneficial to uniformly disperse the raw materials inside the mixing barrel, thereby helping to improve the uniformity of raw material mixing.

[0021] Preferably, the inclined stirring device further comprises:

[0022] A second motor is fixed inside the cylinder cover via a mounting bracket;

[0023] A cross plug block is rotatably mounted on the bottom of the mounting frame and is coaxially fixedly connected to the second motor;

[0024] A cross slot, fixedly embedded in the top of the fixing plate;

[0025] When the barrel cover is opened, the second motor will not drive the installation box to rotate. When the barrel cover is closed, the second motor starts and drives the cross plug block connected to it to rotate through the output shaft, the cross plug block drives the cross slot to rotate, the cross slot drives the fixed plate to rotate, and the fixed plate drives the installation box to rotate, thereby realizing the rotation drive of the installation box, and the installation box drives the connecting frame and the rotating base to rotate, thereby driving the inclined stirring rod and the rotating shaft to revolve while rotating, which is beneficial to stirring and mixing various positions inside the mixing barrel through the stirring rod, thereby helping to improve the uniformity of mixing the coating raw materials.

[0026] Preferably, the feeding assembly comprises:

[0027] A plurality of feeding pipes are installed in a circular array through the top of the cylinder cover, and the top of the feeding pipe can be connected to an external feeding pipe;

[0028] A plurality of sealing rings are arranged corresponding to the feeding tubes and fixed inside the corresponding feeding tubes;

[0029] A plurality of first blocking mechanisms are respectively installed inside each of the feeding pipes and are used to block the inside of the sealing ring;

[0030] A connecting pipe, fixedly connected to the top of the installation box, and the bottom of the connecting pipe is connected to the interior of the mixing cylinder;

[0031] A lifting pipe is vertically inserted into the connecting pipe and driven to move vertically by a lifting mechanism;

[0032] A second blocking mechanism is installed between the lifting pipe and the connecting pipe, and is used to block the connecting pipe;

[0033] A straight rod, fixed inside the lifting tube, used to push the first blocking mechanism and the second blocking mechanism to release the blocking when moving upward;

[0034] When the lifting tube rotates to align with the feeding tube, the control unit controls the lifting mechanism to start, and after the lifting mechanism starts, the lifting tube is driven to move upward, and after the lifting tube moves upward, it is inserted into the bottom of the feeding tube. When the lifting tube moves upward, it drives the straight rod to move upward, and the straight rod moves upward to push the sealing plug to move upward and separate from the sealing ring, so that the inside of the feeding tube is unobstructed;

[0035] When the lifting tube moves upward, the second docking ring is simultaneously driven to move upward. After the second docking ring moves upward, the first docking ring is exposed, so that the first docking ring and the second docking ring blocked by the misalignment of the through opening are unblocked, so that the raw materials can pass through the lifting tube and the connecting tube from the feeding tube to enter the interior of the mixing barrel for feeding;

[0036] After the cylinder is started, the push plate is driven to move upwards through the telescopic rod, and the push plate drives the lifting tube to move upwards, thereby realizing the vertical drive of the lifting tube.

[0037] Preferably, it also includes:

[0038] A scraper is fixed between the rotating base and the mounting box, and the scraper is in contact with the inner wall of the mixing barrel, and is used to scrape the raw materials on the inner wall of the mixing barrel downwards;

[0039] When the rotating base rotates, the scraper is driven to rotate. After the scraper rotates, the paint attached to the side wall of the mixing cylinder is scraped off the side wall of the mixing cylinder, thereby helping to avoid the situation where the paint adheres to the side wall of the mixing cylinder and is difficult to stir and mix, thereby helping to improve the mixing uniformity of the paint.

[0040] Preferably, it also includes:

[0041] Two spiral blades are symmetrically fixed to the upper and lower parts of the rotating shaft, and the two rotating shafts are both arranged in a conical shape, and the wide ends are arranged opposite to each other;

[0042] When the interior of the mixing barrel is full of paint, it is difficult for the paint to flow after the scraper scrapes off the inner wall of the mixing barrel, resulting in the paint still accumulating on the side wall of the mixing barrel. Through the setting of the spiral blades, the spiral blades transport the paint at the bottom to the middle of the rotating shaft, and then the stirring rod in the middle of the rotating shaft stirs the paint to the surroundings. As a result, when the paint at the bottom of the mixing barrel is transported to the middle, a space is formed at the bottom of the mixing barrel, so that the paint on the inner wall of the mixing barrel scraped by the scraper flows downward, and then continues to be transported to the middle of the rotating shaft by the spiral blades, thereby realizing the edge flow of the paint inside the mixing barrel, which is beneficial to improve the uniformity of paint mixing.

[0043] Preferably, it also includes:

[0044] A cylinder is rotatably mounted on the bottom of the mounting box;

[0045] A torsion spring is installed inside the cylinder, and its two ends are fixedly connected to the cylinder and the installation box respectively;

[0046] A plurality of scraping strips are fixed to the side wall of the cylinder in a circumferential array, the scraping strips being in contact with the bottom of the mounting box;

[0047] A plurality of stoppers are fixed on the inner wall of the mixing barrel in a circumferential array, and the stoppers are arranged in a one-to-one correspondence with the scraping strips;

[0048] The installation box rotates and drives the scraper bar to rotate through the cylinder. When the end of the scraper bar encounters a block, the rotation of the scraper bar is blocked, causing the scraper bar to rotate relative to the installation box, thereby scraping the bottom of the installation box through the scraper bar, which is beneficial to scrape the paint attached to the bottom of the installation box and drop it to the inside of the mixing cylinder for re-mixing. When the scraper bar is blocked by the block and rotates relative to the installation box to the position of the connecting frame, the connecting frame exerts a rigid push on the scraper bar, causing the scraper bar to break through the block, thereby allowing the scraper bar to return to its natural state under the action of the torsion spring until it encounters the next block.

[0049] In a second aspect, a mixing method of a crack-resistant hot-melt road marking paint mixing device is provided, wherein a plurality of pressure sensors corresponding to the feeding pipe are fixedly mounted on the inner wall of the cylinder cover, and a push block is mounted on the side wall of the connecting pipe, and the mixing method comprises the following steps:

[0050] The control unit acquires pressure information from the pressure sensor, where the pressure information includes first position information of the corresponding pressure sensor;

[0051] The control unit generates deceleration control information according to the pressure information, and the deceleration control information is used to control the inclined stirring device to decelerate;

[0052] The control unit sends the deceleration control information to the tilting stirring device to control the tilting stirring device to decelerate;

[0053] During the loading process of the loading component, the pressure sensor generates pressure information after being pressurized, and then sends the pressure information to the control unit. After receiving the pressure information, the control unit generates deceleration control information according to the pressure information, and sends the deceleration control information to the inclined stirring device, so that the inclined stirring device decelerates after receiving the deceleration control information. Therefore, when the loading component is loading, the lifting tube can be aligned with the loading tube so that the second motor stops and the first motor slows down, so that the installation box stops revolving and the lifting tube is aligned with the loading tube for loading. At the same time, the first motor slows down to drive the stirring rod to slow down the stirring speed, which is beneficial to avoid high-speed stirring causing the raw materials in the mixing barrel to be thrown into the interior of the loading tube and cause pollution.

[0054] Preferably, the control unit includes a user terminal and further includes:

[0055] The control unit acquires material loading sequence information from the user terminal, wherein the material loading sequence information includes second position information of the material loading tube corresponding to the type of raw material;

[0056] The control unit acquires first position information of the pressure information when acquiring the pressure information;

[0057] When the first position information is equal to the second position information, the control unit generates feeding control information, and the feeding control information is used to control the start of the lifting mechanism;

[0058] When the first position information is different from the second position information, the control unit generates drive control information, and the drive control information is used to control the tilting stirring device to continue rotating;

[0059] The control unit sends the feeding control information to the lifting mechanism, or sends the driving control information to the tilting stirring device;

[0060] The staff can input the loading sequence information through the user terminal. The loading sequence information includes the loading sequence of each raw material. Each raw material corresponds to a different loading tube. Therefore, the loading sequence information includes the second position information of the loading tube corresponding to each type of raw material.

[0061] The control unit acquires the corresponding first position information contained in the pressure information when acquiring the pressure information;

[0062] When the first position information is equal to the second position information, that is, the lifting tube is aligned with the feeding tube corresponding to the raw material to be fed, the control unit generates feeding control information and sends the feeding control information to the lifting mechanism, so that the lifting mechanism starts to push the lifting tube upward to feed the raw material after receiving the feeding control information;

[0063] When the first position information is different from the second position information, that is, the loading tube aligned with the lifting tube is not the loading tube corresponding to the raw material to be loaded, the control unit generates drive control information and sends the drive control information to the inclined stirring device, so that the inclined stirring device continues to rotate after obtaining the drive control information to drive the lifting tube to the position of the next loading tube.

[0064] Preferably, it also includes:

[0065] The control unit obtains stirring time information t1 from the inclined stirring device;

[0066] The control unit obtains the standard time t2 from the user terminal;

[0067] The control unit brings the stirring time information t1 and the standard time t2 into the judgment formula t2≥t1, and when the judgment formula is met, the control unit generates reversal control information, and the reversal control information is used to control the tilt stirring device to rotate in reverse;

[0068] The control unit sends the reversal control information to the tilt stirring device;

[0069] The inclined stirring device times the stirring time to generate stirring time information t1, and then sends the stirring time information t1 to the control unit. The staff inputs the standard time t2 from the user end. The standard time t2 is the set time for a single same-direction stirring. The control unit puts the stirring time information t1 and the standard time t2 into the judgment formula t2≥t1. When the judgment formula is met, the control unit generates reversal control information and sends the reversal control information to the inclined stirring device to control the inclined stirring device to rotate in the opposite direction.

[0070] Compared with the prior art, the present invention has the following beneficial effects:

[0071] The present invention adopts the arrangement of an inclined stirring device. Since the stirring of the inclined stirring device is stirring in an inclined direction, the stirring of the inclined stirring device can be divided into two stirrings in the horizontal direction and the vertical direction, thereby driving the coating raw materials entering the mixing barrel to flow vertically and horizontally, which is beneficial for the coating raw materials to flow in all directions inside the mixing barrel, thereby facilitating the uniformity of the raw material stirring.

DETAILED DESCRIPTION

[0081] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0083] Rotate the base 102 to rotate the bottom of the mixing barrel 1;

[0084] The mounting box 205 is rotatably mounted on the top of the mixing barrel 1 and is connected to the rotating base 102 via a plurality of connecting frames 103;

[0085] The inclined stirring device is installed between the rotating base 102 and the installation box 205, and the raw materials inside the mixing drum 1 are turned vertically and horizontally at the same time by stirring in an inclined direction;

[0086] A feeding assembly is installed between the drum cover 101 and the installation box 205 and is used to feed raw materials into the mixing drum 1;

[0087] A control unit installed inside the installation box 205, used to control the stirring speed of the inclined stirring device, so as to slow down the stirring speed of the inclined stirring device when the feeding assembly is feeding;

[0088] When mixing the paint, if the volume of the mixing container is too large and the paint itself has a certain viscosity, it is difficult for the paint to flow and mix in all directions inside the container when the paint is stirred by a horizontal stirring roller, which will cause uneven stirring of the paint and affect the quality of the paint;

[0089] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the staff controls the feeding component to feed the material through the control unit. First, the feeding component is controlled to feed half of the capacity of the interior of the mixing barrel 1. Then, the control unit controls the inclined stirring device to start. Since the stirring of the inclined stirring device is stirring in an inclined direction, the stirring of the inclined stirring device can be divided into two stirrings in the horizontal direction and the vertical direction, thereby driving the coating raw materials entering the interior of the mixing barrel 1 to flow vertically and horizontally, which is conducive to making the coating raw materials flow in all directions inside the mixing barrel 1, thereby facilitating the uniformity of the raw material stirring;

[0090] By first injecting half of the raw material into the mixing drum 1, the inclined stirring device reduces the resistance of the raw material to the inclined stirring device when stirring the raw material, which is conducive to repeated mixing of a small amount of raw material, and then the control unit controls the feeding assembly to continue injecting the raw material into the mixing drum 1, so that the original raw material in the mixing drum 1 has been mixed evenly, which is conducive to improving the efficiency of mixing the raw materials evenly.

[0091] In summary, by setting up an inclined stirring device, the mixing efficiency and mixing uniformity of the raw materials can be improved, thereby improving the quality of the raw material mixing.

[0092] As an optional embodiment, the inclined stirring device includes:

[0093] The rotating shaft 201 is rotatably mounted between the rotating base 102 and the mounting box 205, and the rotating shaft 201 is tilted;

[0094] A plurality of stirring rods 2 are fixedly mounted in a circular array at the middle of the rotating shaft 201 for stirring the raw materials, and the stirring rods 2 are in a twisted shape;

[0095] A fixing plate 206 is detachably fixed on the top of the installation box 205;

[0096] The first motor 202 is fixed on the top of the fixing plate 206, and the output shaft of the first motor 202 passes through the fixing plate 206 and is fixed with the first gear 203;

[0097] The second gear 204 is rotatably mounted on the mounting box 205 and is coaxially fixedly connected to the rotating shaft 201. The second gear 204 is meshed with the first gear 203.

[0098] After the first motor 202 is started, the output shaft drives the first gear 203 connected thereto to rotate. After the first gear 203 rotates, it drives the second gear 204 meshing therewith to rotate. The second gear 204 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the stirring rod 2 to rotate, so that the stirring rod 2 mixes the raw materials inside the mixing drum 1. The stirring rod 2 is in a twisted shape, so that the stirring rod 2 can drive the raw materials in all directions, which is beneficial to uniformly disperse the raw materials inside the mixing drum 1, thereby helping to improve the uniformity of raw material mixing.

[0099] As an optional embodiment, the inclined stirring device further comprises:

[0100] The second motor 3 is fixed inside the cylinder cover 101 through a mounting bracket 301;

[0101] The cross plug block 302 is rotatably mounted on the bottom of the mounting frame 301 and is coaxially fixedly connected with the second motor 3;

[0102] A cross slot 303, fixedly embedded in the top of the fixing plate 206;

[0103] When the barrel cover 101 is opened, the second motor 3 will not drive the installation box 205 to rotate. When the barrel cover 101 is closed, the second motor 3 is started and drives the cross plug block 302 connected thereto to rotate through the output shaft, the cross plug block 302 drives the cross slot 303 to rotate, the cross slot 303 drives the fixed plate 206 to rotate, and the fixed plate 206 drives the installation box 205 to rotate, thereby realizing the rotation drive of the installation box 205, thereby driving the connecting frame 103 and the rotating base 102 to rotate through the installation box 205, thereby driving the inclined stirring rod 2 and the rotating shaft 201 to revolve while rotating, so as to facilitate the stirring and mixing of various positions inside the mixing barrel 1 through the stirring rod 2, thereby facilitating the uniformity of mixing the coating raw materials.

[0104] As an optional embodiment, the feeding assembly includes:

[0105] A plurality of feeding pipes 4 are installed in a circular array through the top of the cylinder cover 101, and the top of the feeding pipe 4 can be connected to an external feeding pipe;

[0106] A plurality of sealing rings 404 are provided corresponding to the feeding tubes 4 and fixed inside the corresponding feeding tubes 4;

[0107] A plurality of first blocking mechanisms are respectively installed inside each feeding pipe 4 and are used to block the inside of the sealing ring 404;

[0108] The connecting pipe 5 is fixedly connected to the top of the installation box 205, and the bottom is connected to the interior of the mixing cylinder 1;

[0109] The lifting pipe 503 is vertically inserted into the connecting pipe 5 and is driven to move vertically by the lifting mechanism;

[0110] A second blocking mechanism is installed between the lifting pipe 503 and the connecting pipe 5, and is used to block the connecting pipe 5;

[0111] The straight rod 504 is fixed inside the lifting tube 503 and is used to push the first blocking mechanism and the second blocking mechanism to release the blocking when moving upward;

[0112] As an optional embodiment, the first blocking mechanism includes:

[0113] A cross bar 401 is fixed inside the feeding tube 4;

[0114] Spring 402, fixed to the bottom of crossbar 401;

[0115] The sealing plug 403 is fixed to the bottom of the spring 402, and the sealing plug 403 is plugged and matched with the sealing ring 404;

[0116] As an optional embodiment, the second blocking mechanism includes:

[0117] The first docking ring 501 is fixed inside the connecting pipe 5;

[0118] The second docking ring 502 is fixed to the bottom of the lifting tube 503;

[0119] The first docking ring 501 and the second docking ring 502 are both provided with openings in a circular array, and the openings in the first docking ring 501 and the second docking ring 502 are staggered.

[0120] As an optional embodiment, the lifting mechanism includes:

[0121] Cylinder 506, fixed inside the mounting box 205;

[0122] The push plate 505 is fixed on the side wall of the connecting pipe 5;

[0123] The cylinder 506 pushes the push plate 505 to move vertically through the telescopic rod;

[0124] When the lifting tube 503 rotates to align with the feeding tube 4, the control unit controls the lifting mechanism to start, and the lifting mechanism starts to drive the lifting tube 503 to move upward. After the lifting tube 503 moves upward, it is inserted into the bottom of the feeding tube 4. When the lifting tube 503 moves upward, it drives the straight rod 504 to move upward. The straight rod 504 moves upward and pushes the sealing plug 403 to move upward and separate from the sealing ring 404, so that the inside of the feeding tube 4 is unobstructed;

[0125] When the lifting tube 503 moves upward, the second docking ring 502 is simultaneously driven to move upward. After the second docking ring 502 moves upward, the first docking ring 501 is exposed, so that the first docking ring 501 and the second docking ring 502 blocked by the misalignment of the through openings are unblocked, so that the raw materials can pass through the lifting tube 503 and the connecting tube 5 from the feeding tube 4 into the interior of the mixing barrel 1 for feeding;

[0126] After the cylinder 506 is started, it drives the push plate 505 to move upward through the telescopic rod, and the push plate 505 drives the lifting tube 503 to move upward, thereby realizing the vertical driving of the lifting tube 503.

[0127] As an optional embodiment, it also includes:

[0128] The scraper 6 is fixed between the rotating base 102 and the mounting box 205, and the scraper 6 is in contact with the inner wall of the mixing drum 1, and is used to scrape the raw materials on the inner wall of the mixing drum 1 downwards;

[0129] When the rotating base 102 rotates, the scraper 6 is driven to rotate. After the scraper 6 rotates, the paint attached to the side wall of the mixing barrel 1 is scraped off the side wall of the mixing barrel 1, thereby preventing the paint from adhering to the side wall of the mixing barrel 1 and being difficult to stir and mix, thereby helping to improve the mixing uniformity of the paint.

[0130] As an optional embodiment, it also includes:

[0131] Two spiral blades 7 are symmetrically fixed to the upper and lower parts of the rotating shaft 201. The two rotating shafts 201 are both conical in shape, and the wide ends are opposite to each other.

[0132] When the interior of the mixing drum 1 is full of paint, it is difficult for the paint to flow after being scraped off the inner wall of the mixing drum 1 by the scraper 6, so that the paint will still accumulate on the side wall of the mixing drum 1. Through the setting of the spiral blade 7, the spiral blade 7 transports the paint at the bottom to the middle of the rotating shaft 201, and then the stirring rod 2 in the middle of the rotating shaft 201 stirs the paint to the surroundings. Therefore, when the paint at the bottom of the mixing drum 1 is transported to the middle, a space is formed at the bottom of the mixing drum 1, so that the paint on the inner wall of the mixing drum 1 scraped by the scraper 6 flows downward, and then continues to be transported to the middle of the rotating shaft 201 by the spiral blade 7, so that the paint can flow at the edge of the mixing drum 1, which is beneficial to improve the uniformity of paint mixing.

[0133] As an optional embodiment, it also includes:

[0134] The cylinder 8 is rotatably mounted on the bottom of the mounting box 205;

[0135] The torsion spring 803 is installed inside the cylinder 8, and its two ends are fixedly connected to the cylinder 8 and the installation box 205 respectively;

[0136] A plurality of scraping strips 801 are fixed on the side wall of the cylinder 8 in a circumferential array, and the scraping strips 801 are in contact with the bottom of the mounting box 205;

[0137] A plurality of stoppers 802 are fixed on the inner wall of the mixing barrel 1 in a circular array, and the stoppers 802 are arranged one-to-one with the scraping strips 801;

[0138] The installation box 205 rotates through the cylinder 8 to drive the scraper bar 801 to rotate. When the end of the scraper bar 801 encounters the block 802, the rotation of the scraper bar 801 is blocked, causing the scraper bar 801 to rotate relative to the installation box 205, thereby scraping the bottom of the installation box 205 through the scraper bar 801, which is beneficial to scrape the paint attached to the bottom of the installation box 205 to the inside of the mixing cylinder 1 for re-mixing. When the scraper bar 801 is blocked by the block 802 and rotates relative to the installation box 205 to the position of the connecting frame 103, the connecting frame 103 produces a rigid push on the scraper bar 801, so that the scraper bar 801 breaks through the block 802, so that the scraper bar 801 returns to its natural state under the action of the torsion spring 803 until it encounters the next block 802.

[0139] like Figure 8 The mixing method of the crack-resistant hot-melt road marking paint mixing device shown in the figure, a plurality of pressure sensors corresponding to the feeding pipe 4 are fixedly installed on the inner wall of the cylinder cover 101, and a pushing block is installed on the side wall of the connecting pipe 5. The mixing method includes the following steps:

[0140] The control unit acquires pressure information from the pressure sensor, where the pressure information includes first position information of the corresponding pressure sensor;

[0141] The control unit generates deceleration control information according to the pressure information, and the deceleration control information is used to control the speed reduction of the inclined stirring device;

[0142] The control unit sends the deceleration control information to the tilting stirring device to control the deceleration of the tilting stirring device;

[0143] During the loading process of the loading component, the pressure sensor generates pressure information after being pressurized, and then sends the pressure information to the control unit. After receiving the pressure information, the control unit generates deceleration control information according to the pressure information, and sends the deceleration control information to the inclined stirring device, so that the inclined stirring device decelerates after receiving the deceleration control information. Therefore, when the loading component is loading, the lifting tube 503 can be aligned with the loading tube 4 so that the second motor 3 stops and the first motor 202 slows down, so that the installation box 205 stops the revolution and the lifting tube 503 is aligned with the loading tube 4 for loading. At the same time, the first motor 202 slows down to drive the stirring rod 2 to slow down the stirring speed, which is beneficial to avoid high-speed stirring causing the raw materials of the mixing barrel 1 to be thrown into the interior of the loading tube 4 to cause pollution.

[0144] As an optional embodiment, the control unit includes a user terminal and further includes:

[0145] The control unit obtains the material loading sequence information from the user end, and the material loading sequence information includes the second position information of the material loading tube 4 corresponding to the type of raw material;

[0146] The control unit acquires first position information of the pressure information when acquiring the pressure information;

[0147] When the first position information is equal to the second position information, the control unit generates feeding control information, and the feeding control information is used to control the start of the lifting mechanism;

[0148] When the first position information is different from the second position information, the control unit generates drive control information, and the drive control information is used to control the tilting stirring device to continue rotating;

[0149] The control unit sends the feeding control information to the lifting mechanism, or sends the driving control information to the tilting stirring device;

[0150] The staff can input the loading sequence information through the user terminal. The loading sequence information includes the loading sequence of each raw material. Each raw material corresponds to a different loading tube 4. Therefore, the loading sequence information includes the second position information of the loading tube 4 corresponding to each type of raw material.

[0151] The control unit acquires the corresponding first position information contained in the pressure information when acquiring the pressure information;

[0152] When the first position information is equal to the second position information, that is, the lifting tube 503 is aligned with the feeding tube 4 corresponding to the raw material to be fed, the control unit generates feeding control information and sends the feeding control information to the lifting mechanism, so that the lifting mechanism starts to push the lifting tube 503 upward to feed the raw material after receiving the feeding control information;

[0153] When the first position information is different from the second position information, that is, the loading tube 4 aligned with the lifting tube 503 is not the loading tube 4 corresponding to the raw material to be loaded, the control unit generates drive control information and sends the drive control information to the inclined stirring device, so that the inclined stirring device continues to rotate after obtaining the drive control information to drive the lifting tube 503 to the position of the next loading tube 4.

[0154] As an optional embodiment, it also includes:

[0155] The control unit obtains stirring time information t1 from the inclined stirring device;

[0156] The control unit obtains the standard time t2 from the user end;

[0157] The control unit brings the stirring time information t1 and the standard time t2 into the judgment formula t2≥t1. When the judgment formula is met, the control unit generates reversal control information, and the reversal control information is used to control the tilt stirring device to rotate in reverse;

[0158] The control unit sends the reversal control information to the tilt stirring device;

[0159] The inclined stirring device times the stirring time to generate stirring time information t1, and then sends the stirring time information t1 to the control unit. The staff inputs the standard time t2 from the user end. The standard time t2 is the set time for a single same-direction stirring. The control unit puts the stirring time information t1 and the standard time t2 into the judgment formula t2≥t1. When the judgment formula is met, the control unit generates reversal control information and sends the reversal control information to the inclined stirring device to control the inclined stirring device to rotate in the opposite direction.

[0160] Working principle of the present invention: the staff controls the feeding assembly to feed the materials through the control unit, firstly controls the feeding assembly to feed half of the capacity of the mixing drum 1, and then the control unit controls the inclined stirring device to start, because the stirring of the inclined stirring device is stirring in an inclined direction, the stirring of the inclined stirring device can be divided into two stirrings in the horizontal direction and the vertical direction, thereby driving the coating raw materials entering the mixing drum 1 to flow vertically and horizontally, which is conducive to making the coating raw materials flow in all directions inside the mixing drum 1, thereby facilitating the uniformity of the raw material stirring;

[0161] By first injecting half of the raw material into the mixing drum 1, the inclined stirring device reduces the resistance of the raw material to the inclined stirring device when stirring the raw material, which is conducive to repeated mixing of a small amount of raw material, and then the control unit controls the feeding assembly to continue injecting the raw material into the mixing drum 1, so that the original raw material in the mixing drum 1 has been mixed evenly, which is conducive to improving the efficiency of mixing the raw materials evenly.

[0162] In summary, by setting up an inclined stirring device, the mixing efficiency and mixing uniformity of the raw materials can be improved, thereby improving the quality of the raw material mixing.

[0163] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
